The present application relates to the field of solar energy utilization technologies, and in particular, to an automatic tracking solar device.

Background technique

To use solar energy efficiently, the normal of the polyabsorber should be aligned with the sun, that is, the normal of the polyabsorber parallel to the direct rays of the sun; because the earth revolves around the sun on the ecliptic plane, forming a declination angle ±23 ^G 27 'changes; and the earth rotates around the earth's axis, forming a solar time angle that varies between ±180° per day, equivalent to a rotation of 15° per hour, so the polyabsorber should be slowly rotated to make its normal time The quasi-sun can use solar energy efficiently. The Chinese patent No. 03113205.7 discloses a large-scale wind-proof automatic tracking solar illuminating device, and the main points of the scheme are: declination angle tracking: the motor drives the nut screw or the ejector rod of the hydraulic cylinder through the deceleration to connect the frame through the moving pair; Sun-time angle tracking: Two motors drive the rotating shaft through deceleration, and synchronously drive the concentrating module, ie, the absorbing material, through the sprocket, pulley and transition gear; the structure is simple, suitable for large-scale solar concentrating equipment, but due to its concentrating module It is necessary to rotate at a speed of 15° per hour, or its frame should be rotated at a speed of 23 ^Q 27 ' per half year, and the speed of the motor is more than 1,000 revolutions per minute. Obviously, the speed reduction device is more complicated. That is, the rotational speed is relatively large; it uses the hydraulic cylinder to drive the frame: The hydraulic cylinder has a large force, but it is not an easy task to accurately control its stroke; its sprocket and pulley drive connection are soft connections, and its transmission accuracy is relatively rigid. The connection is poor, the transmission chain of the transition gear transmission is too long, and the transmission error is large; the sprocket, pulley and transition gear synchronous drive are not said.

Chinese Patent Application No. 89221656.5 discloses a solar energy tracking device with controllable potential energy. The main points of the scheme are: elastic force or gravity driving the movement of the polyabsorber, photoelectric control of the electromagnet, and the release of the movable tooth. The scheme is simple, but the moving tooth piece can only be rotated to the left. How does the polyabsorber reverse the automatic reset? When the wind is large, the collecting light absorber is easy to swing. Chinese Patent Application No. 91211146.1 discloses a self-tracking device for a differential solar cooker. The main points of the scheme are: Horizontal (ie, solar time angle?) The tracking mechanism is engaged by the electromagnet of the tooth with a fixed tooth; (ie, declination angle?) Tracking by the motor to drive the bevel tooth, the conical tooth and the nut conjoined body, the nut to drive the lead screw, and the rocker arm to drive the solar cooker; the characteristics of the scheme are most similar to the features of the present application, but I am not sure The horizontal tracking is how to track the sun. The longitudinal tracking is driven by a motor. The motor is non-intermittent and has a large rotating speed. The bevel gear transmission has a small reduction ratio, so the tracking accuracy is slightly smaller than the screw ratchet scheme of the present application. difference. Application number is

Chinese Patent Application No. 200520079018.1 discloses a tunable reflector of a horizontal row of solar collector tubes, the main points of which are: The main shaft is connected by a connecting rod to connect the same row of multiple reflectors; which saves many trackers, but Obviously, the problem that the thermal expansion and contraction of the main axis of the sun directly affects the angle of each reflector is not considered; from the abstract drawing, the main shaft is sleeved on the bracket, and the main shaft can only slide back and forth, but cannot move up and down. Bring two problems: 1. The main shaft articulated link is not specified. If the main shaft and the connecting rod are welded, the reflector cannot rotate. 2. If the main shaft is an articulated connecting rod, the reflector can only rotate at a small angle. .

The automatic tracking solar device (hereinafter referred to as a tracking device) according to claim 1 is characterized in that the controller controls the pusher mounted on the bracket to intermittently drive the ratchet device, and the ratchet device connects and drives the polyabsorber to rotate and track the sun, that is, by the control The device is mainly controlled by time, adjusted by light sensing control, and precisely controls the push-pull device mounted on the bracket, and the push-pull device drives the push-pull member to reciprocate intermittently at a fixed distance. The ratchet device is driven by a large reduction ratio to make the ratchet output. The fixed angle or fixed distance movement is accurately transmitted by the connecting transmission member, driving the polyabsorber to rotate and track the sun, so that the normal of the polyabsorber is always parallel to the direct light of the sun or the direct light of the sun is reflected by the mirror. Quasi-absorber, even if the absorber acquires the maximum amount of solar radiation. Because the Earth's revolution forms a declination angle that varies between ±23 ^Q 27 '; and the Earth's rotation forms a solar time angle that varies between ±180° per day, equivalent to a rotation of 15° per hour, both of which change slowly.

Deceleration, so that the pusher can drive the feed condenser to rotate only a few degrees or less on average, and use the connecting transmission to prevent thermal expansion and contraction to reduce the tracking error and control the tracking error. Even higher requirements are met within a few tenths of a millimeter.

The pusher is a machine that drives the push-pull piece to reciprocate intermittently at a fixed distance by electric energy or mechanical energy or potential energy; the push-pull member is a terminal part of the power output of the push-pull device, and may be a push-pull rod, a slider, an armature, a piston The rod, the push rod, the connecting member, etc., may be the armature of the electromagnet, or the push-pull rod of the connecting rod mechanism, or the push-pull rod of the cam mechanism, or the push rod of the airbag, or the piston rod of the cylinder or the cylinder, It acts to transmit torque and connection; The fixed distance is that each stroke of the motion is equal, that is, a length, and the main function of the pusher is to provide a sufficient driving force for the tracking device. The electromagnet pusher is composed of a power source, an excitation coil, a core, and an armature. The power source may be an alternating current supplied by a commercial power supply, or a direct current supplied by a photovoltaic battery or a battery, and the armature is connected to the rocker in the ratchet set. Install a block on the chassis, limit the stroke of the armature and the rocker, make the reciprocating stroke of the armature a fixed distance, and install a return spring on the rocker or armature; the core of the electromagnet is connected to the bracket or the chassis, when the controller is powered The excitation coil and the excitation coil of the electromagnet generate a magnetic field, that is, a feed force is generated, and the suction armature moves the rocker to move toward the iron core, thereby rotating the ratchet by a certain angle, that is, a ratchet circumference corresponding to the ratchet The center angle, that is, the ratchet rotates one tooth. When the controller cuts off the power supply of the electromagnet, the armature is reset by the tension or thrust of the return spring or under the action of gravity, that is, the armature moves with the rocker in the direction of the block. The claw is disengaged from the ratchet or slides on the ratchet, that is, the ratchet does not move, thereby implementing the pusher intermittently driving the ratchet; the electromagnet is pushed Simple structure, but the smaller the suction generated by the excitation coil, which is more suitable for driving the tracking light in a single cohesive attraction. The connecting rod pusher is composed of an electric motor, a flywheel, a clutch and a connecting rod mechanism. The connecting rod mechanism has many types, and can be mounted on the crank shaft by a crank, a crank hinge connecting rod, a connecting rod of the connecting rod, and a push rod. The guide sleeve can be slid and the guide sleeve is fixed to the chassis. This is called a crank slider mechanism, which is driven by a crank to drive the connecting rod, and the connecting rod drives the push-pull rod to reciprocally push and pull in the guide sleeve; or can be cranked Mounted on the crankshaft, the crank slides to connect the rocking lever: that is, the crank can be hinged to the rocker guide sleeve, the rocker guide sleeve, the hollow sleeve swinging rod, or the crank is mounted with a sliding shaft, and the sliding shaft can be mounted with a rolling sleeve or a roller, the swinging rod A sliding slot is opened at one end, and a sliding shaft or a rolling sleeve or a roller is installed in the sliding slot and can be slid or rolled. The rocking rod is hinged at one end or connected to the chassis by a bearing, the hinged slider at the other end, and the slider is installed in the sliding slot. The sliding slot is fixedly connected with the push-pull rod, the push-pull rod is installed in the guide sleeve and can be slid, and the guide sleeve is fixed to the chassis. This is called a swinging guide rod mechanism, and the crank rod drives the rocker guide sleeve or The sliding shaft rotates, thereby causing the swinging rod to swing, the swinging rod drives the slider to move the sliding slot, and the push-pull rod is reciprocally pushed and pulled in the guiding sleeve, thereby showing that the function of the link mechanism is to change the rotating motion into a linear reciprocating motion, and The crank axis is a fixed distance from the hinge or the axis of the slide shaft, so the reciprocating stroke of the push rod is a fixed distance. The cam pusher is composed of an electric motor, a flywheel, a clutch and a cam mechanism. The cam mechanism has various types, and the cam can be mounted on the cam shaft, and the cam end surface has an annular cam groove. The push rod is mounted in the guide sleeve and can slide. The guide sleeve is fixed to the chassis, the one end of the push-pull rod is connected to the roller, the other end is connected to the rocker in the ratchet set, or the pawl in the articulated or sliding connection ratchet pair, and the roller sleeve can be installed with a rolling sleeve or a roller, a roller or a rolling sleeve Or the roller is mounted in the cam groove and slides along the cam groove. The rotation of the cam causes the roller or the rolling sleeve or the roller to slide or roll along the cam groove, and the push-pull rod is reciprocally pushed and pulled in the guide sleeve. This is called a geometrically closed cam mechanism. The cam may be mounted on the camshaft, the push-pull rod is mounted in the guide sleeve and slidable, and the guide sleeve is fixed to the chassis.

Keeping in contact with the cam profile, the cam rotation causes the push-pull rod to reciprocally push-pull and slide in the guide sleeve. This is called a force-closed cam mechanism, so that the function of the cam mechanism is to change the rotary motion into a linear reciprocating motion, and the cam groove Or the highest point to the lowest point of the cam profile is a fixed distance, so the reciprocating stroke of the push-pull rod is a fixed distance. The motor of the connecting rod or the cam pusher is controlled by a controller, and the motor is mounted on the bracket or the chassis to provide torque. The flywheel mounted on the motor shaft functions to store torque by inertia and make the low-power motor intermittent. The high-power ratchet, the motor shaft, the crank shaft or the cam shaft may be the same shaft, the flywheel is connected to the clutch, and the other end of the clutch is connected to the crank or the cam, and the function is to make the continuous rotation of the motor change intermittently. Therefore, the motor is frequently started. The clutch is generally controlled by an electromagnetic friction clutch, which is controlled by the controller. When the controller energizes the excitation coil of the clutch, the clutch engages, and the motor drives the flywheel, clutch, crank or cam to rotate for one week, the clutch is controlled. The clutch power supply is disconnected, the clutch is disengaged, the crank or the cam stops rotating. Because the connecting rod or cam mechanism has the motion inertia, in order to make the push rod stroke accurate, a brake can be installed at the crank or cam, and the clutch can be braked immediately. , the brake is generally made The electromagnetic friction brake is controlled by the controller. Generally, the clutch and the brake are de-energized at the same time. When the brake is powered off, the spring immediately drives the brake pad to brake; the crank or the cam rotates once, and the push-pull rod is driven to reciprocate and push once, thereby driving the connection ratchet. The rocker in the group or the hook of the hinged or sliding connection ratchet pair reciprocates once, thereby rotating the ratchet by a certain angle by the pawl, and the pawl is detached from the ratchet or slides on the ratchet, that is, the ratchet does not move, during resetting, Thereby, the pusher is intermittently driven to drive the ratchet. The reciprocating motion of the connecting rod or the cam push-pull push-pull rod is continuous motion, which is more suitable for tracking the reverse reset of the poly-absorber in the east-west direction, that is, the solar time angle.

The airbag pusher is composed of a gas pump or a gas compressor, a gas tank, a solenoid valve, and an air bag for airbags. The airbag is connected to the bracket or the chassis at one end, the push rod is connected at one end, and the rocker is connected to the rocker in the ratchet group. For the soft body, when the driving air pressure is different, the stroke of the push rod is not a fixed distance, so install a block on the chassis, limit the stroke of the push rod, make the reciprocating stroke of the push rod a fixed distance, in the rocker or putter A return spring can be mounted on it. The cylinder push-pull device is composed of a gas pump or a gas compressor, a gas cylinder, a solenoid valve, and a cylinder air tube, and the cylinder is connected to a bracket or a chassis. The cylinder has a piston and a piston connected to the piston rod, and the cylinder chamber is divided into a piston by a piston. Cavity and reset chamber, the end of the piston rod is the reset chamber, the other end is the feed chamber, the piston rod is connected to the rocker in the ratchet set, or the pawl in the ratchet set is hinged or slidably connected, on the rocker or the piston rod A return spring can be installed. The cylinder push-pull device is composed of a fuel tank, an oil pump, a oil tank, a solenoid valve and a cylinder oil pipe. The oil cylinder is connected to a bracket or a chassis. The cylinder has a piston and a piston connected to the piston rod. The cylinder chamber is divided into a feed chamber by the piston and The reset cavity, the end of the piston rod is a reset cavity, The other end is a feed chamber, the piston rod is connected to a rocker in the ratchet set, or the pawl in the ratchet pair is hinged or slidably connected, and a return spring can be mounted on the rocker or the piston rod. Since the stroke of the cylinder or the cylinder piston is a fixed distance, the reciprocating stroke of the piston rod is a fixed distance. The function of the air pump, gas compressor and oil pump is to provide pressure, that is, to convert mechanical energy into potential energy. When the system pressure is lower than the rated pressure, the air pump or the gas compressor or the oil pump operates, when the system pressure reaches the rated pressure, the air pump or The gas compressor or oil pump stops running; the function of the gas tank and the oil tank is to store and stabilize the pressure, so as to avoid frequent starting of the air pump, the gas compressor and the oil pump, and the gas pump, the gas compressor, the oil pump, the gas tank and the oil tank are collectively referred to as the power source. The function of the solenoid valve is to switch the direction. Generally, two-position three-way or two-position four-way solenoid valve is used, that is, one in one out, one closed, three-way, two-in and two-out, four-way, one straight in and out, one bit The oblique in and out is two digits, and the transposition is realized by the reversing electromagnet and the return spring or the two reversing electromagnets driving the spool; the two-way three-way solenoid valve connecting pipe scheme is: air tank, airbag Or the cylinder feed chamber, the atmosphere, or the oil tank, the cylinder feed chamber, the oil tank, such as when the solenoid valve is in the feed position, the gas tank is connected to the air bag or the cylinder feed chamber, or the oil tank is connected to the cylinder feed chamber, and The mouth of the atmosphere or the mouth of the fuel tank is connected to the closed port. When the push rod or the piston rod is pushed forward by the pressure, the solenoid valve is in the reset position, the gas tank or the tank port is connected to the closed port, the air bag or the cylinder feed chamber is connected to the atmosphere, or The cylinder feed chamber communicates with the fuel tank, and the push rod or the piston rod is reset by the tension or thrust of the return spring or under the action of gravity. The two-way four-way solenoid valve connection piping scheme is: air tank, cylinder feed chamber, cylinder reset chamber, atmosphere, or oil tank, cylinder feed chamber, cylinder reset chamber, fuel tank; eg solenoid valve at feed position The gas tank communicates with the cylinder feed chamber, or the oil tank communicates with the cylinder feed chamber, and the cylinder reset chamber communicates with the atmosphere, or the cylinder reset chamber communicates with the oil tank, and the piston rod advances under pressure pushing; then the solenoid valve is in the reset position The gas tank is connected to the cylinder reset chamber, or the oil tank is connected to the cylinder reset chamber, the cylinder feed chamber is connected to the atmosphere, or the cylinder feed chamber is connected to the oil tank, and the piston rod is reset under pressure. The role of airbags, cylinders and cylinders is to convert pressure into push-pull force, which is to convert potential energy into mechanical energy. Airbags, cylinders and cylinders are collectively referred to as actuators; the role of fuel tank is to store liquid medium, to recycle medium, liquid medium oil Non-corrosive liquid such as water. When the controller sends a feed signal, the commutating electromagnet causes the solenoid valve to be in the feed position, and the push rod or the piston rod is pushed forward under the pressure push, thereby rotating the ratchet by a certain angle by the pawl; When the reset signal is issued, the return spring or the reversing electromagnet keeps the solenoid valve in the reset position, and the push rod or the piston rod pushes the rocker or the pawl together under the pressure push or under the tension or thrust of the return spring or under the action of gravity. Reset, at this time the pawl is disengaged from the ratchet or slides on the ratchet, that is, the ratchet does not move, thereby realizing the pusher intermittently driving the ratchet. Since the power source of the airbag or the cylinder or the cylinder pusher can be separated by a long distance and then connected by a pipe, it is particularly suitable for square array tracking of multiple condensers in different directions, such as a tower solar boiler requiring each mirror. A set of trackers, so that a large number of actuators can use a power source. The push-pull members of the above six types of pushers are all intermittent motion controlled by the controller, and are set as a distance The reciprocating push-pull movement, that is, the stroke distance of each push and pull is equal, which makes the ratchet wheel or ratchet pair ratchet rotate at the same angle every time, that is, the ratchet rotates intermittently at a fixed angle, each time is rotated one Tooth, which lays the foundation for the tracking device to accurately track the sun; and because the push-pull member is subjected to a large enough magnetic field suction or torque generated by the push-pull force or pressure or pressure during the movement and at the point of going back and forth The generated push-pull force or spring force or the action of gravity or braking friction can effectively prevent the influence of the wind on the tracking angle when the wind is large or provide the braking force to prevent the wind from being affected, that is, the various forces described above Both play a braking role, so they can be collectively referred to as braking force.

The ratchet device is driven by a large reduction ratio transmission of the intermittent transmission mechanism, and a driving angle of the driving output member, or a large reduction ratio of the intermittent transmission mechanism, and a fixed distance or a fixed angle is transmitted through the continuous transmission mechanism and the driving output member. The intermittent transmission mechanism is a transmission mechanism that changes the continuous motion into an intermittent motion, that is, the active member of the motion pair performs intermittent motion when the active member performs continuous motion, and the continuous motion includes reciprocating continuous motion; The output member is the terminal part of the transmission, and the fixed rotation angle is equal to the central angle of each rotation. The continuous transmission mechanism is a transmission mechanism for continuous motion, that is, when the active part of the motion pair is continuously moving. The follower also performs continuous motion. The main function of the ratchet is to minimize the feed rate and make the transmission more precise with a large reduction ratio transmission. The core components are the ratchet set, the ratchet pair and the ratchet string. The ratchet set is composed of a rocker with one end empty sleeve or a bearing mounted on a ratchet shaft or a transmission shaft or a screw, and a ratchet that is hinged or slidably coupled to the pawl and the pawl on the rocker; The ratchet pair consists of a ratchet or a ratchet that is hinged or slidably coupled to the push-pull member of the push-pull device (excluding the electromagnet and the airbag pusher); that is, the ratchet pair is composed of a pawl and a ratchet, and the ratchet set is composed of a ratchet pair Composition with a rocker. The rocker in the ratchet group functions to amplify the torque by using the principle of the lever and simultaneously accelerate the deceleration. The rocker is sleeved at one end or mounted on the ratchet shaft or the transmission shaft or the screw with the bearing, and the other end is connected with the push-pull member due to The connection point is an arc swing around the axis of the ratchet in a certain angle range, and the push-pull member of the pusher is linearly reciprocating at a certain distance, so the connection between the push-pull member and the rocker is as follows: It can be a push-pull device Hinged bracket or chassis, push-pull hinged rocker, that is, push-pull device, rocker are all swinging; also can be a push-pull member hinged a top rod, a top rod hinged rocker, that is, push-pull fixed, ejector and rocker swing; The push-pull can be fixed, and the push-pull member is slidably connected with the rocker: a sliding shaft is mounted on the end of the push-pull member, a rolling sleeve or a roller is mounted on the sliding shaft, and a sliding slot is opened at one end of the rocker, the sliding shaft or the rolling sleeve or The roller is installed in the sliding slot and can slide or roll; or the rocker guide sleeve can be hinged at the end of the push-pull member, the rocker sleeve is sleeved in the rocker guide sleeve and can slide. Since the armature of the electromagnet pusher and the iron core are loosely engaged, the armature and the rocker can be hinged or fixedly connected or integrated; since the airbag is a soft body, the push rod and the rocker of the airbag pusher can be hinged or fixedly connected. Or one; the above six connection schemes can well solve the problem that the rocker and the pusher are different in motion. The ratchet wheel or the ratchet wheel or the ratchet wheel in the ratchet string may be a typical acute-angled ratchet or a moment. The toothed ratchet can also be an involute ratchet, that is, an involute gear is used as a ratchet. The ratchet tooth can be made on the outer edge of the wheel, or can be made on the end face, and can be a full round ratchet, or Is a semi-circular ratchet, or it can be a central angle

^47° arc ratchet, the ratchet can be a key connection or an empty sleeve mounted on the ratchet shaft or the transmission shaft, or the ratchet and the nut can be the same body, and the nut is screwed to the screw, that is, the ratchet is supported on the screw by the nut, The ratchet end face may be bolted or riveted or welded to the end face of the polyabsorber. The ratchet shaft or the drive shaft or both ends of the screw are mounted on the chassis or the bracket by bearings. The main function of the ratchet is to reduce the speed ratio, if the ratchet is The number of teeth is 2, and each push or pull of the push-pull piece rotates only one tooth, that is, only rotates 1/Z circle, which is much simpler than the structure of the gear reducer, and its reduction ratio is similar to that of the worm gear, but Worm gears are much easier to machine. The pawl in the ratchet set or the ratchet pair or the ratchet string may be a straight claw or a claw or a double claw or a pin or a claw or a claw or a pin, and the straight or the claw is engaged with the acute ratchet. The claw is shaped like an acute angle with the ratchet end, the one side of the angle is a straight side, the other side is a circular side, the straight side is engaged with the ratchet tooth surface as an engaging edge, the arc side is in contact with the tooth top as a sliding side, and the straight claw is pushing The ratchet and the claw are pull ratchets, the claws of which are hinged on the rocker or the push-pull member or the swing rod, the swing rod is a swing rod in the ratchet string; the pawl engaged with the rectangular tooth ratchet is hinged or slidably connected to the rocker Or a push-pull member or a swinging rod, wherein the hinged pawl has an acute angle with the ratchet engaging end claw, the one side of the corner is a straight side, the other side is a concave arc side, and the straight side is engaged with the ratchet tooth surface, the circle The arc edge is in contact with the tooth tip as a sliding edge, and the claw is generally formed as a bilateral claw, that is, a symmetrical structure and two sharp angles with symmetry. The motor drives the pawl to reverse in both directions, so the claw is called a bilateral claw; The pawl of the rocker or push-pull or swinging lever is mounted on the slide The slot slides in the sliding slot, and the sliding slot is fixed on the rocker or the push-pull member or the swinging rod. The claw is engaged with the ratchet end claw shape: a trapezoidal claw mixed with the ratchet rectangular tooth, and a trapezoidal shape The two waists can respectively engage the ratchet tooth surface, so the claw must be disengaged from the ratchet when the rocker or the push-pull member or the swing rod is reset, and must be inserted between the ratchet teeth when the rocker or the push-pull member or the swing rod is fed. The clutch is controlled by an electromagnet and a spring. When the electromagnet is energized, the pawl is sucked away from the ratchet. When the electromagnet is de-energized, it is engaged with the ratchet under the spring compression, so the claw is called a pin claw; the other is a triangular claw, which is always The ratchet tooth surface is engaged as a meshing edge, and the straight edge is in contact with the tooth tip as a sliding edge. The claw can not only slide in the sliding groove but also rotate 180°, so the claw is called a rotating claw; The friction block is hinged to the other end of the pawl, and the pawl is hinged on the rocker or the push-pull member or the swing rod. When the ratchet rotates clockwise, the friction block acts to cause the pawl to engage with the ratchet by lever action. When the ratchet rotates counterclockwise, Friction block through the bar The action causes the pawl to move away from the ratchet and over the top of the tooth. Here, the forward and counterclockwise rotation is only a hypothesis, the two can be reversed, this is called the claw; the pin tooth is the pawl that meshes with the involute ratchet. The claw shape is an involute, but slightly smaller than the involute gear tooth, that is, the gap between the involute tooth ratchet is slightly larger, and other features, connections, functions, principles, and the like are the same as the pin claws, so The claws are called pin teeth. All pawls without special instructions are by gravity or mounted on the rocker Or the spring force of the spring on the push-pull member or the swing rod keeps the pawl engaged with the ratchet, the spring force cannot be too large, and the pawl resets without sliding the ratchet wheel when sliding on the ratchet tooth tip; except for the pin claw and the latch tooth If all the pawls outside the pawl are engaged with the ratchet during the feed, they will slide on the ratchet tip when resetting, that is, the sliding edge of the pawl contacts and slides with the ratchet tip; for convenience, the following ratchet pair The ratchet group and the reversal scheme are named after the pawl, such as the hook ratchet pair: the pawl is the claw and the ratchet is the acute ratchet. It can be seen that each push-pull movement of the push-pull device pushes the ratchet group or the ratchet wheel in the ratchet wheel to reciprocate, and the pawl and the ratchet tooth surface engage, push or pull the ratchet to rotate a certain angle, that is, the ratchet rotates one tooth. When the push-pull member is reset, the pawl is disengaged from the ratchet or slides on the ratchet tooth tip, and the ratchet wheel is not moved, and the ratchet wheel is intermittently rotated; since the push-pull member pushes and pulls each time, the ratchet wheel rotates only one tooth, so the ratchet set or the ratchet wheel The main function of the secondary is to achieve large ratio reduction, intermittent feed, and precise transmission with a simple structure.

The ratchet string is a transmission mechanism driven by a multi-stage intermittent transmission mechanism with a large reduction ratio; the multi-stage is two or more stages, and the intermittent transmission mechanism may be a ratchet or a sheave or a partial gear mechanism. The ratchet is typical and the most familiar intermittent transmission mechanism. It is the representative of the intermittent transmission mechanism. The string is a number of consecutive lines. Therefore, the multi-stage intermittent transmission mechanism is called a ratchet string in series, such as a ratchet group driving the ratchet group. Driving the ratchet set; the ratchet string in the ratchet is composed of a ratchet set or a ratchet pair driving a single or multi-stage ratchet or sheave or a partial gear mechanism, ie the first stage of the ratchet string is designated as a ratchet mechanism. The said sheave mechanism is composed of a dial and a sheave, wherein the dial is a driving wheel, the sheave is a driven wheel, the dial has a round pin, and the outer edge is composed of a large arc and a small concave arc. There are Z radial grooves on the wheel and a Z-shaped concave arc on the outer edge. When the concave arc of the groove is caught by the convex arc of the dial, the groove is stationary, so the concave arc of the groove is called In order to lock the arc, the function is to accurately align the round pin with the radial groove. When the round pin just enters the radial groove, the intersection of the convex arc and the concave arc of the dial is just aligned with the midpoint of the locking arc. The W lock arc just starts to be loosened, after which the round pin drive sheave rotates 1/Z turn, the round pin leaves the radial groove, the lock arc is stuck again, the sheave is stationary, and the movement is repeated; the dial rotates One turn of the groove wheel rotates 1/Z circle, and the groove wheel stops when it is moving, so the sheave mechanism is an intermittent transmission mechanism. The incomplete gear mechanism is an intermittent transmission mechanism evolved from a gear mechanism, that is, one or a few teeth on the driving wheel and one tooth in the ratchet string, so it is called a single-toothed gear. And the driven wheel makes a tooth that meshes with the driving wheel teeth, that is, the driven wheel can be a complete gear or an incomplete gear between the locking arc and the tooth; for example, only one tooth on the driving wheel, the tooth Hereinafter, the single tooth, the driven wheel has z teeth, the driving wheel rotates one turn, the driven wheel rotates 1/Z circle, that is, the driven wheel stops when the time is moving, so the incomplete gear mechanism is the intermittent transmission mechanism; the tracking device has the brake The incomplete gear mechanism may not have a lock-up arc, otherwise a lock-up arc should be made. The ratchet string has a driving wheel and a driven wheel in each stage, and the teeth or grooves on all the driven wheels are evenly distributed. The driven wheel of the latter stage is called the terminal wheel. In the ratchet mechanism, the ratchet is the driven wheel, the pawl is the active part, and the wheel that drives the pawl movement is the driving wheel; the driven wheel and the driving wheel of the adjacent two stages, that is, the upper wheel The primary driven wheel and the primary driving wheel can be coaxial or the same body. The coaxial connecting body means that the two are connected by bolts or bolted or riveted or welded on the same axis, and the same body is integrated. It means that the same material is processed into two, and the two axes are the same, or the single tooth can be fixedly connected to the driven wheel of the upper stage; if the stage is a ratchet mechanism, the swing rod can be slidably connected to the upper stage. On the driven wheel, that is, a sliding shaft is mounted on the driven wheel of the upper stage, and a rolling sleeve or a roller is mounted on the sliding shaft, and a sliding groove is opened at one end of the swinging rod, and the sliding shaft or the rolling sleeve or the roller is installed in the sliding groove. When the driven wheel of the upper stage rotates, the sliding shaft or the rolling sleeve or the roller is driven to slide or roll in the sliding groove to drive the swinging rod to swing; or the swinging rod guide sleeve is hinged on the driven wheel of the upper stage, The pendulum rod is placed in the swing rod guide sleeve The sliding wheel of the upper stage is rotated by the swinging guide sleeve, and the swinging rod is driven to swing; the swinging rod and the rocking rod in the ratchet set and the swinging rod in the connecting rod mechanism are the same type. It is only for the purpose of not causing confusion and different names in different mechanisms. The structure, function, and installation connection are equivalent to those described above. The ratchets to which the pendulum is connected and the ratchets to which the pawls are engaged are also the same as described above. The main function of the ratchet string is to realize the large reduction ratio transmission with a simple structure to minimize the feed amount and make the transmission more precise. For example, the ratchet group drives the ratchet group to drive the ratchet string of the ratchet group, and if the number of teeth of the three-stage ratchet is Z , the reduction ratio of the ratchet string is the cubic ratio of Z, that is, the first-stage driving wheel rotates Z ³ turns, and the third-stage ratchet rotates once; thus, the ratchet string can be realized with a very short transmission chain. The small feed rate, which is the inevitable result of the large reduction ratio, lays the foundation for solving the technical problem of short transmission chain and accurate tracking angle.

The circumferential ratchet is a rotary output ratchet, which is mostly used for the concentrating and tracking of the concentrating body. The transmission precision can be divided into three-stage transmission precision: The transmission precision consisting of the ratchet group or the ratchet pair is low, and the gear is driven by the ratchet mechanism. Or the worm gear mechanism is centered in the transmission precision, and the transmission precision composed of the ratchet string is high. They are suitable for different precision tracking. The connection between the ratchet mechanism and the gear or worm gear mechanism can be: ratchet and gear in the ratchet mechanism The first driving gear of the mechanism is coaxially connected or the same body, or the ratchet in the ratchet mechanism is coaxial with the worm and is connected by a key to the rack or the screw or the connecting rod ratchet as a line output ratchet, that is, its output The parts are for linear motion (except for the double crank connecting rod ratchet), which are suitable for all movement modes of the polyabsorber; the line output ratchet has many combinations, which can evolve a variety of transmission precisions and are suitable for different tracking. Precision requirements. The rack ratchet device is composed of a ratchet mechanism or a ratchet string driving rack, wherein the ratchet wheel of the ratchet mechanism is an involute ratchet wheel or the terminal wheel of the ratchet string can directly mesh the driving rack when the terminal wheel of the ratchet string is a gear, the ratchet of the ratchet mechanism Or the ratchet wheel or the sheave of the ratchet string can be coaxially connected or coaxial with a gear, and the gear meshes to drive the rack. The above involute tooth ratchet, terminal gear, coaxial joint or the same body gear is called gear one. Of course, it is also possible to add a gear set to the gear set by the gear set after the gear one; The rack slides in the guide rail, and the rail is fixedly mounted to the chassis or the bracket. The screw ratchet device is composed of a ratchet mechanism or a ratchet string drive nut and a screw. The ratchet wheel of the ratchet mechanism or the terminal wheel of the ratchet string is coaxially connected or the same with the nut, and the inner diameter of the ratchet or the terminal wheel can be made into a nut. The nut is screwed to the screw, and the nut is connected to the chassis or the bracket through the bearing connection. When the nut rotates, the screw is linearly moved, and the screw does not rotate relative to the bracket. The connecting rod ratchet is composed of a ratchet string driving link mechanism, and the connecting rod mechanism is of various types, which may be an articulated connecting rod on the ratchet string terminal wheel, a connecting rod hinge push-pull rod, a push-pull rod installed in the guide sleeve and sliding The guide sleeve is fixed to the chassis, which is called a crank slider mechanism, which is driven by the terminal wheel to rotate the connecting rod, and the connecting rod drives the push-pull rod to reciprocately slide and slide in the guide sleeve; or the push-pull rod is hinged at the terminal wheel at one end. The other end is hinged on the concentrating body or the frame, and the distance from the axis of the terminal wheel to the axis of the hinge is smaller than the distance from the center of rotation of the absorbing body or frame to the center of the hinge. This is called a double crank mechanism and is driven by the rotation of the terminal wheel. Push-pull rod push-pull movement, push-pull rod forward, poly-absorber or frame forward rotation, push-pull rod pull back, poly-absorber or frame reverse; push-pull rod in double crank mechanism is actually connecting rod, but in order to The name of the output member is unified, so it is called a push-pull rod. The ratchet string terminal wheel of the connecting rod ratchet rotates one turn, and the polyabsorber or frame is reversed once. Since the push-pull member of the push-pull device reciprocates at a fixed distance, and the ratchets of the ratchet mechanism and the teeth or grooves on all the driven wheels of the ratchet string are uniformly distributed, the output of the rotary output ratchet is a fixed angular movement due to the teeth. The pitch of the strips is equal everywhere, the lead of the screw is equal everywhere, the distance between the axis of the terminal wheel and the axis of the hinge in the link mechanism is a certain number, that is, the radius of the crank is a certain number, so the output of the wire output ratchet is determined Distance sports.

In order to solve the technical problem described in the present application, the automatic tracking solar device according to claim 4 of the present application is composed of a polyabsorber, a controller, a motor mounted on the bracket, a ratchet column connected to the motor, and a connecting transmission member. The mounting on the bracket includes direct and indirect mounting on the bracket, and the ratchet row is driven by a multi-stage intermittent transmission mechanism, a large reduction ratio transmission, a driving output member, or a multi-stage intermittent transmission mechanism. The gear with a large reduction ratio after the transmission is driven by the continuous transmission mechanism and the driving output member; it may be a circumference or a rack or a screw or a connecting rod ratchet column, wherein the circumferential ratchet is arranged as a rotating output ratchet column, a rack or a screw or The connecting rod ratchet is arranged as a line output ratchet train; the circumferential ratchet row is composed of a ratchet string, the rack ratchet row is composed of a ratchet string driving rack, and the screw ratchet row is composed of a ratchet string driving nut and a screw. The connecting rod ratchet column is composed of a ratchet string driving link mechanism; the collecting and absorbing body, the connecting transmission member, the intermittent transmission mechanism, the output member, Corner, continuous transmission, are the same as given distance 1. The claims, said ratchet string specified as a first-order non-ratchet mechanism, other structure, principle, and so the same effect in 1 of the claims. The circumferential ratchet train is both a ratchet string, but the first stage of the ratchet string of the ratchet train is not designated as a ratchet mechanism. If the first stage is a sheave or a partial gear mechanism, the dial or the single tooth The gear is connected to the motor shaft by a key. If the first stage is a ratchet mechanism, a flywheel is connected to the motor shaft by a key, and the flywheel is slidably connected to the swing lever. The sliding connection and the flywheel function are equivalent to the above; the rack and the rack are The screw ratchet row is the same as the rack or screw ratchet driven by the ratchet string. Of course, the first stage of the ratchet string is a non-designated ratchet mechanism; the connecting rod ratchet column is the same as the connecting rod ratchet, but here the ratchet string The first stage is a non-designated ratchet mechanism; the rotary output ratchet train refers to a ratchet train whose output member is a rotary motion, and the line output ratchet train refers to a ratchet train whose output member is a linear motion. Since the motor is rotated at a constant speed and the teeth or grooves on all the driven wheels of the ratchet row are evenly distributed, the output shaft of the rotary output ratchet is a fixed angular movement, since the pitch of the rack is equal everywhere, the guide of the screw The distance is equal everywhere, and the distance between the axis of the terminal wheel and the axis of the hinge in the link mechanism is a certain number, that is, the radius of the crank is a certain number, so the output of the line output ratchet column is a fixed distance movement. Since the polyabsorber operates very slowly, and the angle of the collected light absorbers is not equal due to the equal stroke of the output of the line output ratchet train or the device, in order to improve the tracking accuracy, the ratchet train should be provided with a clutch; the clutch can be controlled by the electromagnet in the ratchet mechanism. The ratchet clutch is realized by the ratchet wheel. Some of the pawls are equipped with electromagnets, such as pin claws, pin teeth, rotary claws, etc., and pawls without self-contained electromagnets such as straight claws and claws can be controlled by electromagnets, electromagnet mounting On the pendulum rod; that is, when the polyabsorber needs to be operated, the electromagnet is de-energized, and under the action of gravity or spring force, the pawl engages the ratchet, and the spring force cannot be too large, and the pawl resets without sliding the ratchet when sliding on the ratchet tooth tip. As a matter of course, when the polyabsorber does not need to be operated, the electromagnet is energized to draw the pawl away from the ratchet, thereby playing a cooperative role; since the number of the ratchet cascade is larger and the speed is lower, the clutch is preferably located in the middle of the ratchet string. Or the last stage; if there is no ratchet mechanism in the ratchet row, the electromagnetic friction clutch can be installed in the ratchet row; the clutch is controlled by the controller, and its function is to make the continuous rotation of the motor By intermittent rotation of the controller, thereby avoiding frequent start the motor, the output line is equal to solve or column output ratchet member polyethylene suction stroke angle unequal light technical problem, to improve tracking accuracy. The automatic tracking solar device according to claim 4 of the present application is controlled by a controller to control a motor mounted on the bracket and a clutch of a ratchet train, the motor drives a ratchet train, and the ratchet row is connected and intermittently drives the polyabsorber to rotate and track the sun; The time control is mainly used, the light sensing control is used as the adjustment, and the clutch of the motor and the ratchet row mounted on the bracket is precisely controlled. The motor drives the ratchet train, and the ratchet train has a large reduction ratio and intermittent transmission, so that the ratchet train output member is fixed at an angle or a fixed angle. Distance movement, accurate transmission through the connecting transmission, driving the suction body to rotate the sun. The ratchet train has a short drive chain, simple structure and high transmission accuracy. It is especially suitable for focusing concentrated light absorbers and tower solar boiler mirrors. The tracking error can be controlled within a few tenths of a millimeter or even more. High requirements, so the main role of the ratchet train is to minimize the feed rate and make the drive more accurate. The difference between the overall solutions of claims 4 and 1 is: First, the basic features are different, the power mechanism of claim 4 is simple, the power mechanism is an electric motor, and the power mechanism of claim 1 is a push-pull device, and the electromagnet is pushed and pulled in the push-pull device. The device is simpler, the rest They are all more complicated, so the basic characteristics are different. Secondly, the functional relationship is different: one is continuous rotation drive intermittent transmission, the other is intermittent reciprocating drive intermittent transmission; the tracking accuracy range is different: the former is narrower and the latter is wider The common technical features of the two are: intermittent transmission mechanisms, specifically ratchet strings.

Since the north-south direction, that is, the declination angle tracking, requires the polyabsorber to rotate between ±23 ^Q 27 ', and the east-west direction, that is, the solar-time angle tracking, requires the poly-absorber to rotate between 150° and 210° per day, that is, tracking 10 per day. It takes 14 hours, so it is necessary to reverse the reset when the polyabsorber is rotated to a fixed point. If the east-west direction is rotated in one direction, there will be 10 to 14 hours of rotation, which is a waste of energy. Therefore, the tracking device should be able to Realize the forward and reverse conversion to solve the above problem. The forward and reverse conversion can be realized in the ratchet mechanism: when the controller sends a reverse signal: the electrosurgical magnet mounted on the rocker or the push-pull member or the swing rod energizes the pawl from the ratchet, Or the device with the motorized claws can brake the brakes to release the brakes, and install the coil springs on the ratchet end faces or the end faces of the collectors, that is, the disc springs or the pulley weights, and drive the concentrated absorbers by potential energy (elastic or gravity). For quick reset, this solution must be equipped with a flexible stop or limit switch at the beginning of the polyabsorber. This scheme is suitable for east-west tracking. It is also possible to use a rectangular tooth ratchet engagement pin or an involute ratchet engagement pin gear, since the polyabsorber is rotated forward: when the pin or the tooth is engaged with the ratchet during feeding, and the pin or the tooth is removed from the ratchet when resetting, The said feed means that the push-pull member feeds or the swing rod swings forward, and the reset refers to the push-pull member reset or the swing rod swings backward. For the convenience of the description, the following three schemes are also used as the convention, that is, the light absorption. When the body is rotating forward: When the pawl is engaged with the ratchet, the pawl slides on the ratchet tip when resetting, so when the controller sends a reverse signal, the controller changes the control line of the electromagnet so that the feed is made. The electromagnet has the electric pin or the tooth to be disengaged from the ratchet, the electromagnet is powered off, the pin or the tooth is engaged with the ratchet, so that the polyabsorber can be reversed; or the rectangular tooth ratchet can be used to engage the rotary claw, when the controller reverses When the signal is received, the electromagnet mounted on the rocker or the push-pull member or the swing rod is powered to suck the pawl away from the ratchet, and the motor rotates the rotary claw by 180°, so that the rotary pawl slides on the ratchet tooth tip during feeding. At reset The rotating claw engages with the ratchet to reverse the concentrated light absorbing body. It is also possible to use a rectangular tooth ratchet to engage the double-sided claw. When the controller sends a reverse signal, the motor drives the double-sided claw to reverse, so that the bilateral claw is at the ratchet during feeding. When the tooth is slid on the top of the tooth and the double-sided claw is engaged with the ratchet during the reset, the poly-absorber is reversed, and the bilateral claw is held by the gravity to keep the pawl in contact with the ratchet without a spring; or the rectangular tooth ratchet can be used to engage the positive and negative double-claw. That is, the two pawls are hinged or slidably connected to the rocker or the push-pull member or the swing rod, and are respectively controlled by two electromagnets mounted on the rocker or the push-pull member or the swing rod, and the poly-absorber is rotated forward. The controller feeds the positive electromagnet to suck up the reverse pawl, and the forward rotation pawl engages with the ratchet or slides on the ratchet tooth tip. When the concentrated light absorber is reversed, the controller feeds the reverse electromagnet to be positive. The pawl is sucked up, and the reverse pawl is engaged with the ratchet or slides on the ratchet tooth tip, thereby realizing the forward/reverse transition. Due to the above scheme of adopting a rectangular tooth or an involute ratchet, the positive and negative reversal speeds of the polyabsorber are equal, Therefore, it is more suitable for tracking in the north-south direction; for example, the push-pull device is a connecting rod or a cam push-pull device, and the reciprocating motion of the push-pull rod can be utilized as a continuous motion, and the poly-absorber that tracks the east-west direction can be quickly reverse-reset, such as using the above. One of the rotary claws, the double-sided claws, one of the positive and negative double-claw reversal schemes, and the clutches are continuously engaged during the entire reversal process, so that the push-pull rods are continuously pushed and pulled, and the poly-absorbent body is quickly reversed and reset. The ratchet train tracking device performs the forward and reverse conversion of the north-south direction tracking, and can be controlled by the controller to control the motor forward and reverse; if there is no ratchet mechanism in the ratchet row and is tracked in the east-west direction, the controller and the brake can be controlled by the controller at the same time. On, that is, the clutch is de-energized, the brake is energized, a coil spring or a pulley weight device is mounted on the end face of the collector, and the poly-absorber is reversed by the potential energy (elastic force or gravity). This solution must be at the beginning of the polyabsorber. A flexible block is placed. It can also realize forward and reverse conversion in other transmission mechanisms: such as rack ratchet or column, gear can be engaged with normal rotation gear 2 and counter gear 3, gear three mesh reverse gear 4, gear 2 and gear 4 Each slides on its axis and respectively meshes with the racks. They cannot mesh with the racks at the same time. Their engagement and disengagement with the racks are controlled by the controller through the electromagnet. When the controller sends a forward rotation signal, the forward-rotating gears are meshed with the racks. The gear drives the gear two to drive the rack to advance straight forward and push the collector to rotate forward; when the controller sends a reverse signal, the reverse gear is meshed with the rack, and the gear drives the gear three to drive the gear to rotate. The four-wheel drive rack of the rotating gear is linearly reset backward, and the poly-absorber is reversed, thereby realizing forward-reverse switching. Such as a connecting rod ratchet or column, the distance from the axis of the ratchet string terminal wheel to the hinge axis of the hinged link is equal to half of the one-way travel of the push-pull rod and the collecting point of the collecting light when the collecting light is rotated, or the terminal is made The distance from the axle center to the hinge axis of the hinged push-pull rod is equal to half of the one-way stroke of the connection point between the push-pull rod and the poly-absorber when the poly-absorber rotates. When the push-pull rod advances, the poly-absorber rotates forward, and the push-pull rod When pulling back, the polyabsorber is reversed, that is, the terminal wheel rotates once, and the polyabsorber rotates once and for all.

Since the wind can blow the absorbing body and affect the tracking angle when the wind is large, the tracking device should be required to have a self-locking or braking function; since the concentrating body is subjected to a sufficient driving force when it is rotated forward or reversed. The driving time is short, the wind direction does not affect the direction of the polyabsorber, and the wind force is less when the direction is the same. Therefore, only the stop of the filter pawl reset and the polyabsorber stop rotating. Braking; that is, the brake can be mounted on the ratchet or column or the polyabsorber. The brake can be controlled by the controller using an electromagnetic friction brake. When the polyabsorber is driven by the driving force, the brake is loose. On, when the polyabsorber stops rotating, when the pawl is reset, the controller cuts off the brake power, and the spring immediately drives the brake pad to brake; the brake can also be a ratchet or a tantalum with a rectangular tooth ratchet, in the chassis or A pin claw is mounted on the bracket, and the claw is controlled by an electromagnet and a spring controlled by the controller, and the polyabsorber is driven by the driving force. When turning, the plug electromagnet gets the electric plug claw out of the ratchet. When the polyabsorber stops rotating, when the pawl is reset, the controller cuts off the power, and the pin is in the spring. The force is inserted into the ratchet teeth to brake; if the tracking device is a screw ratchet or a column, because the nut is screwed to the screw, and the screw connection has self-locking property, that is, when the spiral angle is less than or equal to the friction angle, No matter how much force the screw shaft is subjected to, the screw can not drive the nut to rotate. That is, the screw mechanism of the present application has a self-locking function, and no brake is required.

The polyabsorber is a substance capable of directly absorbing solar energy or absorbing or reflecting solar energy or reflecting or transmitting solar energy to other light absorbing bodies after focusing or reflecting; for example, a photovoltaic panel for absorbing solar energy, a solar cooker, and a flat plate collecting heat Parabolic mirrors, hemispherical mirrors, flat mirrors, compound parabolic mirrors, composite mirrors, Fresnel lenses, Fresnel mirrors, such as reflective or transmissive solar energy, are all polyabsorbers. Since the polyabsorber supported on the bracket must rotate and track the sun to efficiently utilize the solar energy, the tracking device of the present application has the following connection method for the connection of the polyabsorber to the bracket: One type of connection is the symmetric ends of the polyabsorber Each of the transmission shafts is connected to the transmission shaft, and the transmission shaft is supported on the two side brackets through the bearing connection, and the polyabsorbent body rotates around the axis of the transmission shaft. This connection method is mostly used for east-west direction tracking, so it is simply referred to as east-west screw connection, which is particularly suitable for multiple The wire-focusing poly-absorber is connected in series, and the east-spinned poly-absorber can be driven by the tracking device of any one of the solutions of the present application; a connecting method is a hinged bracket at the center of the back-yang surface of the poly-absorber, and the bracket is a single The column, or the hinged bracket at the center line of the back side of the polyabsorber, the bracket is two or more columns, and the plurality of columns are arranged in a straight line, and the collecting body swings around the center line thereof, and the connection mode is mostly used in the north-south direction. Tracking, so this is abbreviated as the north-south hinge, which is especially suitable for the poly-absorber as a composite anti-theft without east-west direction tracking. Tracking of the mirror, the north-south hinged polyabsorber can be driven by a line output ratchet or column; a connection method is that the bracket is divided into two parts: a frame and a column, and the symmetric ends of the polyabsorber are connected to the drive shaft, the drive shaft Supported on the frame by a bearing connection, a plurality of poly-absorber strings can be connected in parallel to be supported on the frame, and a plurality of poly-absorbers are connected and driven by the connecting transmission member, and a single column is hinged at the center of the back-yang surface of the frame, or The center line of the back side of the frame is hinged to two or more uprights, and the plurality of uprights are arranged in a straight line. The polyabsorber can be rotated about the axis of the drive shaft and driven by a rotating or line output ratchet or column mounted on the frame. At the same time, it can be oscillated with the frame around the center line of the frame, and can be realized by swinging the wire output ratchet or column drive frame mounted on the column. This connection mode can simultaneously track four directions from east to west and north and south, which is simply referred to as a square joint, which is special. It is suitable for square array tracking of multiple poly-absorbers in series and parallel; one connection method is that the bracket is divided into two parts: frame and column, and the absorption of the light is The two ends are respectively connected to the transmission shaft, and the transmission shaft is supported on the frame through the bearing connection. The plurality of poly-absorbent bodies can be connected in series and supported on the frame in parallel, and the plurality of poly-absorbers are connected and driven by the connecting transmission member, and the frame is driven. The north and south end of each connection line outputs a ratchet or column output member, a line output ratchet or a column connection column, and the frame swings around the center line of the frame by the up and down movement of the output member, and the line output ratchet or column linkage at the north and south ends , that is, when one end moves upward The other end moves downward, and the absorbing light body can be rotated around the axis of the transmission shaft and driven by a rotating or linear output ratchet or column mounted on the frame. The connection mode can simultaneously track four directions from east to west and north and south, which is simply referred to as Four-way connection, which is especially suitable for the short north-south end of the frame, the parallel connection of the poly-absorber, and the inability of the column to connect to the middle of the frame due to the rigidity of the frame; a connection method is the center of the back-positive surface of the poly-absorber through the spherical bearing connection The column, the east-west direction and the north-south direction are respectively installed with one or two symmetrical line output ratchets or column tracking devices. If the symmetrical two tracking devices are installed, the two tracking devices must be linked, that is, one is extended and the other is retracted. The movement makes the poly-absorber swing around its center, and realizes tracking in four directions from east to west, referred to as quadrilateral ball joint. It is especially suitable for tracking of spot-focusing dish-shaped polyabsorbers such as solar cookers and different positions of multiple polyabsorbers. The square array is tracked, such as the tracking of tower solar boiler mirrors. In summary: There are two main ways of collecting light-absorbing body. One is that the symmetrical ends of the poly-absorber are connected to the drive shaft, and the poly-absorber rotates around the axis of the drive shaft. This method is mostly used for east-west tracking. Therefore, it is simply referred to as east-west rotation. One is that the center of the back side of the polyabsorber or frame is connected to the column, and the poly-absorber or frame swings around its center line, so it is simply referred to as the center swing. The five types of connection methods described above each have their applicable scope, and can be said to be the main way of integrating all the absorption and absorption connections of the existing solar tracking device. Therefore, the tracking device of the present application has a wide application range.

The connecting transmission member refers to a connecting transmission member between the output member of the ratchet or the column and the collecting and absorbing body, and the output member is rotated or linearly moved, and the output member of the rotating output ratchet or the column can be directly connected to the absorbing light. The body, such as a polyabsorber, rotates for something, and the output member can be connected to the drive shaft by a key, that is, a ratchet or a column drive output member mounted on the bracket or the chassis, and the output member drives the polyabsorber to rotate through the drive shaft; The output member is bolted or riveted or welded on the end face of the polyabsorber, and the output member directly drives the polyabsorber to rotate. The above connection is called a fixed connection, and the transmission chain is short and has no gap; if it is a plurality of polyabsorber strings When connected in parallel, a plurality of collecting bodies of the same axis may be firstly connected in series by a longitudinal rod, and a sprocket or a toothed belt pulley is mounted on the end face of the first collecting body of each axis, and a chain is also mounted on the output member. a wheel or a toothed belt pulley, the output member and the poly-absorber of the same end face are connected by a chain or a toothed belt, and all the light absorbing bodies are driven to rotate synchronously by the output member; When the light body is connected in series, the output member is connected with a vertical axis by a key, and each group is provided with a sprocket or a toothed belt pulley on each of the vertical axes, and each group is connected with a group of the same end face of the light absorbing body by a chain or a toothed belt. The output shaft drives the longitudinal axis and the vertical axis to drive all the polyabsorber rotation; the connection is a chain or a toothed belt linkage, which is called a tooth connection, and is characterized in that the tooth connection has no slipping connection with respect to the flat belt and the pulley rope connection, so The transmission is relatively accurate and is suitable for series and parallel connection of parallel axes but not in one plane. For example, the support bracket of the polyabsorber or frame is the center swing of two or more columns, and may be a rotary output ratchet or column mounted on the column, the output member of which is mounted at one end of the polyabsorber or the frame and its axis of rotation and convergence Rotation axis of the light absorbing body or frame Coincident, the output member drives the polyabsorber or the frame to rotate and oscillate. Since the output member of the rotary output ratchet or the column is rotated at a fixed angle and is fixedly connected or toothed or rigidly connected to the polyabsorber, the driven absorbing body is also rotated at a fixed angle.

In order to solve the technical problem described in the present application, the connecting transmission mechanism according to claim 5 of the present application is composed of a polyabsorber, a hinge and a parallel link; the connecting transmission mechanism, that is, the parallel linkage mechanism, is a parallel connecting rod. A plurality of parallel polyabsorbers are hinged in parallel, that is, when a plurality of parallel polyabsorbers are connected in series, a plurality of polyabsorbers of the same axis are sleeved in series by a longitudinal rod, and a plurality of parallel polyabsorbers are hinged and connected in parallel by a parallel link. That is, the parallel connecting rod is hinged at the bottom of the first end face of the first collecting end of the same end face, such as a rotating output ratchet or column, the axis of the mounting output member is parallel to the axis of the collecting body, and the end face of the parallel connecting member of the connecting rod is The output member drives all the absorbing materials for synchronous rotation; if it is a wire output ratchet or column, the output member is hinged to a push rod, the push rod is hinged parallel link, and all the absorbing materials are driven by the output member for synchronous rotation; For example, the linkage mechanism of the train wheel, its scientific name is a parallelogram linkage mechanism, so its connecting rod is called a parallel connecting rod, and its mechanism is called a parallel connecting rod mechanism. The sleeve is a small end sleeve which is sleeved in the big end and can slide axially to prevent thermal expansion and contraction. The longitudinal rod is installed at the highest position of the polyabsorber; the bottom refers to the polyabsorber normal line. The lowest position of the back face, the normal line is perpendicular to the polyabsorber and the line passing through the axis is the normal, such as the line perpendicular to the opening of the parabolic mirror and the line passing through the axis is the normal, the intersection of the normal and the frame is At the bottom of the parabolic mirror, a crossbar is fixedly connected to the normal plane of the back surface of the flat collector, and the lowest end of the crossbar is the bottom of the flat collector; the hollow steel such as square steel is used for the parallel connecting rod. Manufactured by a circular tube or the like, the parallel connecting rod end is connected to the cooling water tank by a hose, and the cooling connecting rod is circulated in the parallel connecting rod cavity by a cooling medium, and the cooling medium may be a liquid such as water or oil, and the cooling is performed. The water tank is filled with a sufficient amount of cooling water; or the parallel link cavity is drawn into a vacuum and filled with a small amount of pentane as a phase change working medium, and the connecting rod is thermostated by a heat pipe principle to prevent the parallel connecting rod from expanding and cooling. Reduce the tracking angle. The parallel connecting rods are rigidly connected and have a constant temperature device, so the transmission is accurate. It is suitable for series-parallel connection of parallel axes and on one plane. It omits many trackers, so the structure is simple. Since the tooth connection is a soft connection, the connecting member changes in straightness and bending when the driving force changes, which affects the accuracy of the transmission. However, the rigid connection does not have this phenomenon, so the parallel link connection is not only much simpler than the tooth connection, and The transmission is more accurate, so the short transmission chain, simple structure and accurate transmission are the main technical problems to be solved in this application, and also the main technical problems that the parallel linkage mechanism should solve and can solve.

Since the output of the wire output ratchet or the column is linear, and the polyabsorber or frame is for rotary motion, the two are preferably slidably connected or hinged by the intermediate member, and may be a hinge of the output member. The slider slides in the sliding slot, or a sliding shaft is mounted on the end of the output member, a roller or a rolling sleeve can be mounted on the shaft, a sliding shaft or a roller or The rolling sleeve slides or rolls in the sliding groove, and the sliding groove is fixedly connected to the back surface of the collecting body or the frame; the sliding groove is a groove, that is, the sliding member can push and pull the sliding groove, and the sliding member only Sliding or rolling, and the sliding groove is mounted in a direction perpendicular to the axis of rotation of the polyabsorber or frame. It is also possible that the output member is hinged to a push rod, and the push rod is hinged on the central end surface or the back side surface of the polyabsorber or the frame; whether it is a sliding connection or a hinge, the direction of the pushing force of the output member is perpendicular to the polyabsorber or the frame. The axis of rotation does not intersect with it, said middle portion being half of the bottom to the axis. The sliding connection or articulation is a rigid connection, which is characterized by a linear motion into a rotary motion, which is suitable for both the east and west rotations and the center swing. The output member of the line output ratchet column or device is linearly moved at a fixed distance, that is, each movement stroke is equal, and the angles of the collected light absorbing bodies are not equal, and the sliding connection is when the connection points of the two are close to the axis of the absorbing light absorber. The angle of rotation is large and the distance is small. The hinge is the angle between the output member and the push rod. When the angle of the absorption body is large, the angle of rotation is small when the angle is large. Since the rain and sun will cause the chain device to rust and the toothed belt to age, the dust will accelerate the wear of the chain device. Therefore, a protective cover should be added to the tooth connecting device to prevent rain, dust and sun.

It is known from the above that: The characteristics of the circumferential ratchet or column are: Simple structure, the driven polyabsorber rotates at a fixed angle, and is especially suitable for east-west rotation tracking; the characteristics of the rack ratchet or column are: rack It is in surface contact with the guide rail and has large contact surface and good rigidity. It is suitable for the support transmission of the frame. The characteristics of the screw ratchet or column are: large reduction ratio, self-locking function, which can omit the braking device and shorten the transmission chain; The characteristics of the rod ratchet or column are: one rotation of the terminal wheel, the polyabsorber or the frame are reversed once, this feature can omit the reversing device; its rotation and line output both have a wide range of uses.

The controller is a controller equipped with a microcomputer or a chip such as a single-chip microcomputer or a programmable PLC, or a strong electric controller; since the earth is slow and continuous with respect to the sun, and the solar radiation is sometimes absent, Therefore, the controller used in the tracking device of the present application is mainly based on time control and responds to the continuous operation of the sun, so as to solve the problem that when the cloud blocks the sun and the sensor does not sense the light to cause the collector to pause for a long time, the sensor light sensing control is Adjustment, to improve the accuracy of tracking, also solve the problem of steering in the winter and summer seasons such as declination tracking, to solve the problem that the output of the line output ratchet or column is equal and the angle of the absorption of the light is not equal, ie the ratchet or column The feed rate of the second time is very small, that is, the feed amount is minimized. If the sensor senses that the tracking is not in the position, the feed is not re-adjusted before the reverse reset point, and only the forward adjustment is made, and the rotation is not reversed; The device or column tracking device can be controlled without adjustment, that is, controlled by a clock chip.

Since the ratchet string is multi-axis transmission, in order to facilitate the manufacture and installation of the tracking device, the chassis should be provided: the push-pull device and the ratchet device can be combined into one chassis, or the push-pull device and the ratchet device can be used separately. The ratchet column is generally used alone. A chassis, the chassis should be easy to repair and heat; the connecting drive is protected by a protective cover. Chassis to fixed tracking It can be installed with lubricating oil to lubricate rotating parts, and it can protect against rain, dust and sun.

The automatic tracking solar device of the present application is precisely controlled by the controller, is driven by the pusher intermittently or the motor is driven at a constant speed, and is driven by a ratchet or a ratchet wheel to reduce the ratio of the fixed angle or the fixed distance to the small feed. Through the parallel link or fixed connection with anti-thermal expansion and contraction, the transmission is driven to drive the poly-absorber to track the sun. When the poly-absorber stops rotating, the brake is braked or the self-locking function of the screw is used to prevent the wind from affecting the tracking angle. And to ensure the consistency of each feed, so the tracking angle is accurate; intermittent drive or transmission, large reduction ratio of the intermittent transmission mechanism, parallel linkage linkage, so the transmission chain is short, simple and reliable structure; The solution or the different combinations: Lists a variety of different types of rattles or columns with different types of poly-absorbers and brackets, different driving force and characteristics, and a variety of ratchets or columns with large range of transmission reduction ratios. Pieces, so the scope of application is wide; the chassis or protective cover is rainproof, dustproof and sun-proof.

The present application will be further described below in conjunction with the embodiments.

The first embodiment is an embodiment of a solar boiler parabolic mirror tracking the sun. Figure 1 is a front view of a mirror support. Figure 2 is a side view of the mirror support. A heat absorbing tube 9 is installed at the focal line of the parabolic mirror 1 (hereinafter referred to as a mirror), and the heat absorbing tubes 9 are connected in series and in parallel to the heat exchange place; the mirror 1 is composed of the panel 11, the frame 2, and the struts 3 The bearing block 4, the flange 5, and the longitudinal rod 6 are composed. The panel 11 is fixed by the frame 2, and the longitudinal rod 6 is welded integrally with the frame 2. The frame 2 is connected to the bearing shell 4 by the tension strut 3, and a bearing bush is arranged in the bearing shell 4, Mounted on the sleeve shaft 10, the bearing seat 4. The bearing bushes are both upper and lower structures. The bearing shell 4 has a pair of flanges 5. The flanges 5 have screw holes, and the upper and lower tile seat pieces are fastened by bolts. The sleeve shaft 10 is welded on the bracket 7, that is, the mirror 1 is symmetric. The sleeve shafts 10 are connected at both ends, and the sleeve shafts 10 are respectively welded on the two side brackets 7, and the heat absorption tube 9 is sleeved in the sleeve shaft 10; the axis of the sleeve shaft 10 and the axis of the heat absorption tube 9 and the focal line of the mirror 1 are the same The mirror 1 is rotatable about its axis. The weight of the lower part of the axis of the mirror 1 is equal to the weight of the upper part, so that the mirror 1 is statically balanced with respect to the axis to reduce the driving torque; the plurality of mirrors 1 of the same axis are connected in series by the longitudinal rod 6 and connected by a parallel link. 8 A plurality of parallel mirrors 1 are hingedly connected in parallel, that is, a hinge is mounted on the bottom of the end face of the first mirror 1 on each axis of the same end face, and the hinge is composed of a round pin 12, a pin sleeve 13, and a pin seat 14, and the pin sleeve 13 Soldering at the bottom of the frame 2, the pin holder 14 is welded to the parallel link 8, and the pin sleeve 13 is connected to the pin holder 14 by a round pin 12 to form a hinge. The round pin 12 and the pin sleeve 13 and the pin seat 14 are all in a dynamic fit. This parallel link 8 hinges a plurality of mirrors 1 in parallel into one unit.

Figure 3 is a schematic diagram of a square array of mirrors. The sleeve is sleeved in the big end, can slide axially with each other to prevent thermal expansion and contraction, and the longitudinal rod 6 is installed at the highest position of the mirror 1; the bottom refers to the mirror 1 normal The lowest position of the upper back face, that is, the line perpendicular to the opening of the mirror 1 and passing through the axis is the normal, the intersection of the normal and the frame 2 is the bottom of the mirror 1; the parallel link 8 is made of hollow square steel The one end of the end is connected to the cooling water tank 15 by the hose 16, and the cooling water tank is filled with a sufficient amount of cooling water, and is naturally circulated and cooled in the cavity of the parallel connecting rod 8 by the cooling water to prevent the parallel connecting rod 8 from expanding and contracting. The illumination angle of the mirror 1 is affected, and the output of the circumferential ratchet 17 is hinged at the other end: the end face of the ratchet wheel 30, the circumferential ratchet 17 is mounted, the axis of the ratchet wheel 19 is parallel to the axes of the mirror 1, and the parallel link 8 is to each axis. Equal to each other, all mirrors 1 are driven by ratchets 30 to rotate synchronously. Since the parallel link is rigidly connected and has a thermostat, the matching clearance between the round pin 12 and the pin sleeve 13 and the pin seat 14 is small, and the thrust of the parallel link 8 to the mirror 1 is always one direction when tracking the sun. Therefore, the parallel link transmission is accurate.

Figure 4 is a schematic diagram of a circular ratchet drive. Since the concentrating light of the mirror 1 is relatively large and requires precise tracking in the east-west direction, the mirror 1 is driven by a circumferential ratchet 17 composed of a three-stage ratchet string; the three-stage ratchet string uses a ratchet group, that is, a ratchet group drives the ratchet group. The ratchet set is driven again, and the swinging rod structure and installation of the three-stage ratchet set are the same, that is, a sliding slot 23 is opened at one end of the swinging rod. (For convenience, all the parts of the same structure are marked with the same icon, and the number of stages is followed by For example, the sliding groove 23 represents a three-stage sliding groove, and the sliding groove 23-2 represents a second-stage sliding groove), and the other end is sleeved or mounted on the ratchet shaft 18 by a bearing; the third-stage pawls are straight claws, The claw is shaped like an acute angle with the ratchet end, the one side of the angle is a straight side, and the other side is a circular side. The straight side engages with the ratchet tooth surface to push the ratchet as the meshing edge, and the arc edge and the tooth tip contact the sliding edge. The two-stage pawl 26 has the same claw shape, and the spring force of the spring 27 keeps the pawl 26 engaged with the ratchet 28, the spring force thereof cannot be excessively large, and the pawl 26 is reset and does not drag when sliding on the tooth top of the ratchet 28 The ratchet wheel 28 is prevailing, and the pawl is hinged on the swing rod 22; the first and second stages are typical acute angle tooth ratchets 28, the third stage: the ratchet wheel 19 is a rectangular tooth ratchet, and the number of teeth of the three-stage ratchet wheel is respectively, Z ₂ Z ₃ , the ratchet is mounted on the ratchet shaft 18 by a key connection, and the ends of the ratchet shaft 18 are mounted on the chassis by bearings. The cam push-pull push-pull rod 29-end-mounted sliding shaft 24-1, the sliding shaft 24 of the three-stage ratchet set can be mounted with a rolling sleeve or a roller, and the sliding shaft 24-1 is mounted on the sliding groove of the first-stage swinging lever 22-1. In 23-1, the pawl 26-1 hinged on the first stage swinging lever 22-1 engages the ratchet 28-1; the first stage ratchet 28-1 is mounted with the sliding shaft 24-2, and the sliding shaft 24-2 is mounted on the first In the sliding groove 23-2 of the secondary pendulum 22-2, the pawl 26-2 hinged on the second stage pendulum 22-2 engages the second stage ratchet 28-2; the second stage ratchet 28-2 is mounted for sliding The shaft 24-3 and the sliding shaft 24-3 are installed in the sliding groove 23-3 of the third stage swinging rod 22-3, and the third stage swinging rod 22-3 is hinged with one positive and one opposite two pawls, and two are installed. The electromagnet, the forward rotation electromagnet 35 corresponds to the reverse pawl 36, the reverse electromagnet 21 corresponds to the forward rotation pawl 20, and the forward rotation pawl 20 or the reverse rotation pawl 36 meshes with the ratchet wheel 30 19 or on the ratchet wheel 30 The top of the tooth is slid, the positive and reverse pawls cannot simultaneously engage the ratchet wheel 30 19, and the ratchet wheel 30 19 articulates the parallel link 8 . When the push-pull rod 29 drives the slide shaft 24-1 to perform a reciprocating push-pull movement, the slide shaft 24-1 slides in the sliding groove 23-1 of the swing rod 22-1, thereby driving the swing rod 22-1 to swing back and forth, and the swing rod When the 22-1 swings to the left, the pawl 26-1 hinged on the swinging lever 22-1 engages the ratchet 28-1, thereby driving the ratchet 28-1 to rotate counterclockwise; when the swinging lever 22-1 swings to the right, the pawl 26-1 slides on the top of the ratchet 28-1, and the ratchet 28-1 does not move; the push-pull rod 29 is pushed and pulled once every time, and the ratchet 28-1 rotates one tooth. The ratchet 28-1 rotationally drives the swing lever 22-2 to swing, the ratchet 28-2 drives the ratchet 28-2 to rotate counterclockwise, the ratchet 28-2 rotationally drives the swing lever 22-3 to swing, and the pawl 20 or 36 drives the ratchet three. 19 rotation, the three-stage ratchet group has the same movement principle. When the mirror 1 is rotating forward, the controller supplies the forward rotation electromagnet 35 to suck the reverse pawl 36 away from the ratchet wheel 30 19, and the forward rotation pawl 20 meshes with the ratchet wheel 30 19 under gravity or the ratchet wheel 30 19 teeth. Sliding on top, when the mirror 1 is reversed, the controller supplies the electric reversing electromagnet 21 to suck the forward rotation pawl 20 away from the ratchet wheel 30 19, and the reverse rotation pawl 36 meshes with the ratchet wheel 30 19 under the action of gravity or The ratchet wheel 30 19 slides up on the top, thereby realizing the forward and reverse conversion. The brake 37 is mounted on the ratchet wheel 30, i.e., the brake 37 is fixed to the chassis and the ratchet wheel 30 is connected by a brake pad. The brake 37 is an electromagnetic friction brake and is controlled by the controller. A small hole 25 is drilled in the ratchet 28-2, and a set of light source and photodiode sensor are respectively mounted on the left and right symmetrical points of the corresponding small hole 25; when the mirror 1 tracks the sun, when the right side sensor senses the light When the clutch 39 is energized, that is, when the sliding shaft 24-3 is in the upper half of the ratchet 28-2 and the clutch 39 is energized, the brake 37 is electrically released, and when the left group sensor senses the light, the sliding shaft 24-3 In the lower half of the ratchet 28-2, and the sliding shaft 24-3 is in the upper half of the ratchet 28-2 but the clutch 39 is de-energized, the controller cuts off the power of the brake 37, and the spring immediately drives the brake pad. Braking is performed, thereby preventing wind from affecting the tracking angle. Figure 5 is a schematic view of a cam pusher. The cam pusher is composed of an electric motor 41, a flywheel 40, a clutch 39, and a cam mechanism. The cam 33 of the cam mechanism is mounted on the transmission shaft 38 through a bearing, and an annular cam groove 34 is formed on the end surface of the cam 33. The push-pull rod 29 is mounted in the guide sleeve 30 and slidable, and the guide sleeve 30 is fixed to the chassis, and the axis of the push-pull rod 29 and the transmission shaft The 38 axes are on the same plane and perpendicular to each other, the push-pull rod 29 is connected to the roller 31, the roller 31 is mounted on the roller 32, the roller 32 is mounted in the cam groove 34 and can be rolled along the cam groove, and the other end of the push-pull rod 29 is mounted with a sliding shaft. 24-1, connecting the swing rod 22-1; the cam 33 - the driven piece of the end face connecting clutch 39, that is, the follower piece of the cam 33 and the clutch 39 are connected by the bearing to the drive shaft 38 without being driven by the drive shaft 38, and the clutch 39 is activated. The plate and the flywheel 40 are keyed to the drive shaft 38. The clutch 39 and the flywheel 40 may be mounted adjacent to each other or may be mounted separately from the motor 41. The clutch 39 is an electromagnetic friction clutch controlled by the controller and energized by the controller 39. The exciting coil and the clutch 39 are engaged, the driving shaft 38 drives the driving piece of the clutch 39, the driving piece drives the driven piece, and the driving cam 33 rotates, and the controller cuts off the power of the clutch 39 and the active of the clutch 39. The blade is separated from the driven piece, and the cam 33 stops rotating; the function of the clutch 39 is to make the continuous rotation of the motor 41 into intermittent rotation, thereby avoiding frequent start of the motor 41, and the flywheel 40 functions to store the torque by inertia; The motor 41 is connected, that is, the rotation shaft of the motor 41 is integrated with the transmission shaft 38, and the motor 41 is mounted on the base. After the mirror 1 starts to track the sun, the controller starts the motor 41 to rotate and feeds the forward rotation electromagnet 35 to suck the reverse pawl 36 away from the ratchet wheel 30 19, and the motor 41 drives the flywheel 40 and the clutch 39 to rotate; the controller is controlled by time. The main light is adjusted by the light sensing control to precisely control the engagement of the clutch 39, the controller power supply clutch 39 engages the clutch 39, and the clutch 39 drives the cam 33 to rotate one revolution; the rotation of the cam 33 causes the roller 32 to roll along the cam groove 34, so that the push rod 29 After reciprocating push-pull and slide in the guide sleeve 30, the controller cuts off the power of the clutch 39 and the brake 37, the clutch 39 is disengaged, the brake 37 is simultaneously braked, and the ratchet wheel 30, the parallel link 8, and the mirror 1 stop moving; the push-pull rod 29 reciprocating push-pull movement, driving the swing rod 22-1 to reciprocate by the sliding shaft 24-1, thereby driving the ratchet 28-1 to rotate counterclockwise by the pawl 26-1; the ratchet 28-1 rotates one turn, passes the sliding shaft 24-2 The driving swing lever 22-2 swings back and forth once, and the ratchet wheel 28-2 drives the ratchet wheel 28-2 to rotate one tooth counterclockwise, the ratchet wheel 28-2 rotates one turn, and the swing shaft 24-3 drives the swing rod 22-3 to reciprocately swing. Once the pawl 20 drives the ratchet wheel 19 rotates counterclockwise a three teeth, driven by parallel links 8 all the mirrors 1 synchronously rotates counterclockwise, thereby achieving an accurate mirrors track the sun. When the mirror 1 is operated to the tracking dead point, the controller sends a reverse signal, the controller continuously supplies the electric clutch 39 and the brake 37, and supplies the electric reverse electromagnet 21 to suck the forward rotation pawl 20 away from the ratchet three 19, the clutch 39 engages and drives the cam 33 to continuously rotate, so that the push-pull rod 29 continuously reciprocates the push-pull movement, the ratchet wheel 19 is driven to rotate clockwise by the reverse pawl 36, and the mirror 1 starts to reverse the reset quickly until the mirror 1 rotates to the tracking start point. The controller simultaneously cuts off the motor 41, the clutch 39, The brake 37 power supply, that is, the cam pusher and the circumferential ratchet 17 are powered off, and the mirror 1 stops rotating. It can be seen that the function of the cam mechanism is to change the rotary motion into a linear reciprocating motion, and since the highest point to the lowest point of the cam groove 34 is a fixed distance, the reciprocating stroke of the push-pull rod 29 is a fixed distance, and since the clutch 39 is intermittently engaged, Therefore, the push-pull rod 29 is an intermittent reciprocating motion controlled by the controller, and the three-stage intermittent motion of the circumferential ratchet device 17 causes the mirror 1 to intermittently rotate to realize slow tracking of the sun; the large reduction ratio of the three-stage ratchet string: X Z2 X Z3: 1 The ratchet wheel 30 19 drives the parallel link 8 with a small feed angle, and is accurately driven by the parallel link 8 with anti-thermal expansion and contraction, and drives the mirror 1 to rotate and track the sun. When the mirror 1 stops rotating, the brake is used. 37 brake anti-winding affects the tracking angle and ensures the consistency of each feed, so the tracking angle is accurate.

Set the number of teeth of the three-stage ratchet, Z ₂ and Z ₃ are 25, then the reduction ratio of the ratchet string is 25 X 25 X 25: 1=15625: 1, that is, the push-pull rod 29 reciprocating feed 15625 times ratchet three 19 rotation one Circle, the mirror 1 rotates 360 times, that is, the push-pull rod 29 feeds once equal to the mirror 1 rotates 360° + 15625=0. 02304°; since the mirror 1 rotates 15° every hour, that is, the push-pull rod 29 The hour is to feed 15. ÷0. 02304° = 651 times, equivalent to feeding once every 5.9 seconds. When the mirror 1 is reversely reset, the mirror 1 is reversed by 180°, that is, the push-pull rod 29 is reciprocatingly fed 15526 + 2=7812. 5 times, the mirror 1 is reversed from the tracking stop point to the tracking start point, and the motor 41 speed is set. For 1500 rpm, that is, the push-pull rod 29 is fed 1500 times per minute, then 7812. 5 ÷ 1500 = 5. 2. That is, 5. 2 minutes mirror 1 is reversed from the tracking stop point to the tracking start point. The motor is 1500 rpm, that is, 1500 X 60 = 90,000 rev / h, and the mirror 1 solar time tracking is 15 ° per hour, that is, 1 / 24 rev / hr, the difference between the two is 2.16 million times; In the example, the motor is driven by deceleration to drive the polyabsorber tracking, how many stages of deceleration is required? In this application, the pusher is intermittently driven, so that the ratchet device can achieve accurate tracking with only three stages of deceleration. It can be seen that the mirror 1 only rotates a few degrees at a time when tracking the sun, and can meet the precision required for the parabolic mirror to track the sun with the largest concentration ratio. Currently, the maximum concentration ratio of the parabolic mirror is 50, and Mirror 1 reset takes only a few minutes, the drive chain has only three stages of deceleration, the drive chain is short, and the structure is simple and reliable.

The second embodiment is an embodiment of a tower solar boiler mirror that tracks the sun. Figure 6 is a square diagram of a tower solar boiler mirror. The tower type solar boiler is composed of a mirror 42, a boiler 43, and a heat transfer device for transferring, storing and using heat. The plurality of mirrors 42 of different orientations and different inclinations reflect the solar radiation to the boiler 43, and are absorbed by the boiler 43 and converted into Thermal energy. Since the orientation or inclination of each mirror 42 in the mirror square is different, each mirror 42 is required to perform precise tracking in four directions from east to west, so that the mirror 42 of the embodiment is connected to a single column by a square ball connection. Figure 7 is a schematic view of a mirror support. The center of the back surface of the mirror 42 is connected to the bracket by a spherical bearing 45: a column 44, a tracking device for mounting a wire output screw ratchet row 48 in the east-west direction and the north-south direction. Through the output member: the up-and-down telescopic movement of the screw 47 causes the mirror 42 to swing around its center to realize tracking in four directions from east to west; FIG. 8 is a schematic diagram of the screw ratchet column. For the convenience, the east-west direction and the north-south direction use the same screw ratchet train 48 transmission, they are only different in control, so only one screw ratchet train schematic is shown in Fig. 8; because the north-south direction is slow to track, only a few feeds per day Second, the east-west direction tracking needs to be fed every few seconds, so the motor 59 tracked in the north-south direction is jogged by the controller, that is, the brake is stopped immediately after starting, so that each jog motor 59 is only One or two revolutions, the motor 59 has its own brake, and the east-west tracking motor 59 rotates continuously after starting; here the brake is only used to ensure the consistency of each feed, so its power is better than the first implementation. The brake 37 in the example is much less powerful. The end of the screw 47 is hinged to a slider 49 via a hinge 50. The slider 49 is mounted in the sliding groove 46 and slidable. The sliding groove 46 is fixedly coupled to the back surface of the mirror 42 and is perpendicular to the axis of rotation of the mirror 42. The sliding groove 46 is a groove, that is, the slider 49 can push and pull the sliding groove 46, and the slider 49 can only slide and cannot rotate, so the screw 47 can only swing relative to the mirror 42 and cannot rotate; the screw 47 Parallel to the column 44 for the up and down push and pull motion, that is, the direction of the pushing and pulling force of the screw 47 is perpendicular to the axis of rotation of the mirror 42 and does not intersect with it; that is, the screw 47 and the mirror 42 are slidably connected, and the connecting member - the hinge 50, the slider 49. The sliding groove 46 changes the linear motion of the screw 47 into the rotational motion of the mirror 42. The screw 47 is linearly moved at a fixed distance, that is, the stroke of each feed is equal, and the angles of the mirrors 42 driven by the screws 47 are not equal. The connection point, that is, the slider 49 is close to the axis of the mirror 42, the angle is large and far. The corner angle is small. The terminal wheel of the ratchet string is a rectangular tooth ratchet, which is the same as the nut, that is, the inner diameter of the ratchet is made into a nut, which is called a nut ratchet 52; the nut ratchet 52 is screwed to the screw 47, and the screw angle is smaller than the friction angle, and the nut ratchet 52 It is connected to the chassis through the bearing 53. The nut ratchet 52-end is locked to the bearing 53 by the snap ring 54 or the retaining nut so as not to move up and down with respect to the chassis, and the chassis is fixedly mounted on the column 44; therefore, the nut ratchet 52 When rotating, the driving screw 47 is moved up and down parallel to the column 44, that is, the screw 47 moves up and down linearly with respect to the column 44 without rotating.

Figure 9 is a schematic diagram of a ratchet string. The swing rod 51 is sleeved on the screw 47 and the other end is sleeved in the swing rod guide sleeve 58 and slidable. The swing rod guide sleeve 58 is hinged on the end surface of the incomplete gear 62, and the incomplete gear 62 is guided by the swing rod. When the sleeve 58 rotates, the swing lever 51 is swung back and forth. A latching claw 55 is slidably coupled to the swinging lever 51, that is, the latching claw 55 is mounted in the latching groove 56 and slides in the latching groove 56, and the latching groove 56 is fixed to the swinging lever 51. The latching pawl 55 is engaged with the nut ratchet 52, and the claw is engaged. The trapezoidal claws which are mixed with the rectangular teeth of the nut ratchet 52, and the trapezoidal two waists thereof respectively mesh with the tooth surface of the nut ratchet 52, so the latch claw 55 must be disengaged from the nut ratchet 52 when the swing lever 51 is reset, and the swing lever 51 is The feed must be inserted between the teeth of the nut ratchet 52. Therefore, the trapezoidal claws 55 are smaller than the two waists of the nut ratchet 52, that is, the meshing gap is large, and the acute angle between the claw and the tooth is rounded, so that The pin claw 55 is inserted into the screw The female ratchet 52 is disposed between the teeth; therefore, an electromagnet 57 is attached to the top end of the latching claw 55. The electromagnet 57 is fixed to the swinging rod 51, and the clutch 57 is controlled by the electromagnet 57 and the spring. When the electromagnet 57 is energized, the pin is inserted. The suction nut ratchet 52 is meshed with the nut ratchet 52 under the compression of the spring when the power is off, and the spring force thereof cannot be excessively large, and the nut ratchet 52 is not dragged when the pin claw 55 is inserted to slide on the tooth top of the nut ratchet 52. Prevail. A trip switch is mounted on each of the upper and lower maximum rotation or swing positions of the swing rod guide sleeve 58 or the swing rod 51. Here, the upper and lower left and right sides are referred to as FIG. 9, and the stroke switch is only a signal element, which can be used as in the first embodiment. The sensor on the ratchet 28-2 is replaced; if the incomplete gear 62 is rotated clockwise, when the upper stroke switch is activated, that is, when the swing rod guide sleeve 58 starts the right half arc stroke, the electromagnet 57 is given by the controller. The electromagnet 57 is energized to suck the pin claw 55 away from the nut ratchet 52, and the swing lever 51 swings downward to reset; when the lower stroke switch is activated, that is, when the swing rod guide sleeve 58 starts the left half arc stroke, the electromagnetic device is broken by the controller. The iron 57 power supply, the pin claw 55 is engaged with the nut ratchet 52 under the pressing of the spring, and the swing lever 51 drives the nut ratchet 52 to rotate clockwise by the pin claw 55. This convention is called a forward rotation line; if the incomplete gear 62 is a smooth When the hour hand is rotated, when the upper stroke switch is touched, the controller cuts off the power of the electromagnet 57, the pin claw 55 engages with the nut ratchet 52, and the swing lever 51 drives the nut ratchet 52 to rotate counterclockwise; when the lower stroke switch is touched, The magnet 57 is energized to suck the pin claw 55 away from the nut ratchet 52, and the swing lever 51 is swung up and reset; this convention is called reverse line, and the two lines are the controller switching control line when the motor 59 is rotating forward, and the control pin is passed. The method in which the claws 55 are engaged to realize the forward and reverse conversion of the mirror 42. The latching pawl 55 also functions as a clutch, that is, the electromagnet 57 is de-energized when the mirror 42 needs to be operated, and the latching pawl 55 engages the nut ratchet 52 under the action of the spring force; the electromagnet 57 is energized when the mirror 42 does not need to be operated. 55 sucks the nut ratchet 52, thereby causing the continuous rotation of the motor 59 to become intermittently controlled by the controller, thereby avoiding frequent start of the motor and improving tracking accuracy. It is of course also possible to mount an electromagnetic friction clutch between the rotating shaft 60 and the single-toothed gear 61, which mounts and controls the clutch 39 as in the first embodiment. The incomplete gear 62 is keyed to the gear shaft 63. The gear shaft 63 is mounted on the casing via a bearing 64. The incomplete gear 62 is an incomplete gear that locks the arc and the gear teeth; the driving wheel that meshes with the incomplete gear 62 Only one tooth is formed, which is called a single-toothed gear 61. The function of the lock-up arc is to accurately align the single-toothed gear 61 between the teeth of the incomplete gear 62, and the single-toothed gear 61 is keyed to the rotating shaft 60 of the motor 59. The motor 59 is mounted on the chassis; the incomplete gear 62 is formed between the teeth that mesh with the single teeth of the single-toothed gear 61. If the incomplete gear 62 is made as a single tooth, the single-toothed gear 61 rotates one turn of the incomplete gear. 62 rotation 1 / turn, that is, the intermittent transmission mechanism when the incomplete gear is stopped. The controller of the embodiment is mainly controlled by time, and is controlled by the sensor light sensing control, and precisely controls the motor 59 and the pin claw 55 acting as a clutch; that is, the screw ratchet row 48 tracked in the north-south direction is: the mirror 42 starts to track the sun. When the tracking device is powered on, when the controller receives the feed signal, the controller jog the motor. 59. After the start, the motor 59 rotates one or two times and then the brake stops. The motor 59 drives the single-toothed gear 61 to rotate, and the single-toothed gear 61 drives the incomplete gear 62 to rotate with the swinging rod guide sleeve 58. 58 drive swing rod 51 reciprocatingly swings, in this case is a forward rotation line, the controller controls the clutch pin 55 and the nut ratchet 52 to disengage, the drive nut ratchet 52 rotates clockwise, and the nut ratchet 52 drives the screw 47 to intermittently feed straight. The drive mirror 42 is driven to rotate the sun by connecting the transmission members. When the sensor senses the light commutation, that is, after the winter and summer seasons are turned, the controller switches the control line to the reverse line, the controller obtains the reset signal, the controller drives the motor 59, drives the single-toothed gear 61 to drive the incomplete gear 62 to drive the swing rod. 51 swinging, by controlling the clutch pin 55, the driving nut ratchet 52 rotates counterclockwise, the driving screw 47 is intermittently linearly reset, and the driving mirror 42 reversely tracks the sun; thereby realizing the mirror 42 tracking the sun in the north-south direction throughout the year. . During this movement, the single-toothed gear 61 rotates once, the partial gear 62 rotates one tooth, the partial gear 62 rotates one turn, the nut ratchet 52 rotates one tooth, the nut ratchet 52 rotates one turn, and the screw 47 pushes or pulls Feed or reset a lead; that is, after three stages of intermittent drive three-stage deceleration. The east-west direction tracking screw ratchet row 48 has the same transmission as the north-south direction tracking. They are only different in control. When the mirror 42 starts to track the sun in the east-west direction, the controller switching control line is a forward rotation line, and after the controller receives the feed signal, The starter motor 59 continuously rotates, and the driving ratchet column drives the mirror 42 to rotate the sun to track the sun. When the up-and-down stroke switches are each triggered once, the controller short-circuits the down-stroke switch line, so that the electromagnet 57 is continuously energized, and the pin claws 55 are sucked. From the nut ratchet 52, the mirror 42 stops rotating; until the controller receives the feed signal again, the controller recovers the short circuit, and the up and down stroke switches are each triggered again, so that the mirror 42 intermittently rotates the sun until tracking Stop. When the mirror 42 starts the reverse reset, the controller switches the control line to the reverse line, and the starter motor 59 rotates continuously, and the driving ratchet column drives the mirror 42 to reverse rapidly until the tracking start point; in this embodiment, the rotary claw and the positive and negative double are used. The claws replace the latch jaws 55 to achieve forward and reverse conversion and disengagement. Since the motor 59 is rotated at the hook speed, the teeth on all the driven wheels of the ratchet row are uniformly hooked, and since the lead of the screw 47 is equal everywhere, the screw 47 is moved at a fixed distance. Since the nut ratchet 52 is screwed to the screw 47 and has a helix angle smaller than the friction angle, it has self-locking property, and the mirror 42 does not need to be mounted with a brake. .

The incomplete gear 62 is 10 teeth, and the nut ratchet 52 is 20 teeth. The reduction ratio of the ratchet string is 200, that is, the motor 59 rotates once, the nut ratchet 52 rotates 1/200 circle, and the lead of the screw 47 is 6 imn. The 0. 0057°, that is, the rotation of the motor 59 is rotated by 0. 0057°, that is, the rotation of the motor 59 is rotated by 0. 0057°. The reduction ratio of the screw ratchet train 48 is 360 ° ÷ 0. 0057 ° = 63157: 1, how many stages of deceleration is required for tens of thousands of times of deceleration with gears? The use of the ratchet column can be achieved only by three stages of deceleration, and the transmission chain of the ratchet train is short and the structure is simple and reliable. Tracking and countering in the north-south direction The mirror 42 needs to rotate ±23 7 ', 23°27 ' ÷0. 0057° -4123 times per year, which is equivalent to 22 times per day; generally no such precise tracking is required, so the north-south tracking controller is jogged every time. The motor 59 is turned two or three times. Since the controller is based on time control and adjusted by sensor light sensing control, the tracking error is less than or equal to the feed amount, so the tracking error of the mirror 42 can be controlled within a few tenths of a millimeter or even more demanding. The east-west tracking mirror 42 is rotated by 7.5° per hour. If the electromagnetic friction clutch is mounted on the rotating shaft 60, the clutch should be engaged with the feed 7.5 ° +0. 0057 ° =1316 times per hour, which is equivalent to every 2. 7 The second feed is performed once; since the mirror 42 of the present embodiment does not need such precise tracking, the pin claw 55 is used as the clutch, and the pin claw 55 is fed once for each engagement, the nut ratchet 52 is rotated 1/20 turn, and the screw 47 is advanced 6 +20=0.3 mm, the mirror 42 is rotated by 0. 057°; the feed is a theoretical value, in fact there is a certain gap in the drive chain, and when the swing lever 51 is reset, the pin claw 55 and the nut ratchet 52 have a small section. Contact, the nut ratchet 52 brake or small angle reversal, so the actual feed amount is the setting value after the installation and commissioning, it is smaller than the theoretical value; the pin claw 55 should be meshed with the feed 7.5 ° +0. 057 ° = 131 times, equivalent to feeding every 27 seconds. It can be seen that the mirror 42 only rotates a few degrees at a time when tracking the sun, which can meet the accuracy required for the tower solar boiler mirror to track the sun. The general boiler 43 is about 100 meters away from the mirror 42. The characteristics of the screw ratchet or column are: large reduction ratio, self-locking function, which can omit the brake device and shorten the transmission chain.
