Referring to fig. 1-4, a preferred embodiment of the present invention is shown.

Profile lift system for an offshore buoy, comprising:

an instrument bar 100 for placing monitoring instruments;

a winding roll 200, the winding roll 200 being substantially cylindrical, having a groove of a certain depth around a cylindrical surface of the cylinder, for winding a wire;

a motor for driving the winding roll 200 to rotate; the motor is powered by a storage battery in the offshore buoy, and the storage battery can be charged periodically and replaced periodically or powered by a solar panel on the offshore buoy or a wind driven generator on the offshore buoy; the rotation of the motor is controlled by a control circuit on the offshore buoy;

one end of the cable 300 is connected to the instrument fence 100, and the other end of the cable 300 is connected to the winding drum 200;

when the monitoring instrument needs to be placed in seawater to a certain depth, the motor drives the winding roller 200 to rotate, the cable 300 is released, and the instrument column 100 descends to a required position along with the release of the cable 300 under the action of gravity;

when the monitoring instrument needs to be lifted, the motor drives the winding roller 200 to rotate reversely, the cable 300 is collected, and the instrument bar 100 is lifted.

A section operating system for marine buoy drives the rotation or the antiport of spiral cylinder 200 through the motor, will settle and stretch into the sea water certain degree of depth or promote from the sea water at monitoring instrument in instrument fence 100 to the monitoring instrument can all monitor the marine environment of the different degree of depth, and is very convenient.

The profile lifting system further comprises an outer frame 400 and a cable tensioner 500, the cable tensioner 500 being arranged on top of the outer frame 400 for keeping the cable 300 in a tight state at all times.

The cable tensioner 500 includes an upper platform 510, a tension spring 520, a bottom plate 530, and a pulley 540, the upper platform 510 being fixedly attached to the top of the outer frame 400, the tension spring 520 being disposed between the upper platform 510 and the bottom plate 530, and the pulley 540 being disposed at the lower portion of the bottom plate 530. The number of the tension springs 520 may be 4, each tension spring 520 has a length of 60mm and an outer diameter of 20mm, and the 4 tension springs 520 are arranged in two sides, and each side is provided with 2 springs. One end of the cable 300 is attached to the instrumentation bar 100 and the cable 300 passes over a pulley 540 on the cable tensioner 500 causing the instrumentation bar 100 to move up and down relative to the cable arrangement.

During the swinging process of the offshore buoy, when the cable 300 changes from a tight state to a loose state, the tension spring 520 is automatically tightened, so that the cable 300 changes from the loose state to the tight state, and the cable 300 is not easy to be locked when being folded. When the toolbar 100 is impacted by sea waves and pulled downwards, the tension spring 520 is stretched to be longer, so that a part of the cable 300 is automatically released, and the cable tensioning device 500 has an automatic adjusting function, so that the cable 300 is not easy to be pulled out.

A tension sensor may be provided on the upper platform 510 of the cable tensioner 500 to coordinate the use of the tension spring 520.

The tension sensor is based on the principle that: the elastic body generates elastic deformation under the action of external force, so that the resistance strain gauge adhered to the surface of the elastic body also generates deformation along with the elastic deformation, after the resistance strain gauge is deformed, the resistance value of the resistance strain gauge is changed, and the resistance change is converted into an electric signal through a corresponding measuring circuit, so that the process of converting the external force into the electric signal is completed.

The tension sensor can monitor the deformation of the tension spring 520, and thus the condition of the instrumentation bar 100 suspended below the cable tensioner 500, for example, if the cable 300 is broken, the cable tensioner 500 is empty and no load. When the suspended instrumentation rail 100 is in a static state, the tension of the cable 300 on the instrumentation rail 100 is equivalent to the gravity of the instrumentation rail itself, and the buoyancy on the instrumentation rail 100 is relatively small and can be ignored; the tension spring 520 receives a force equivalent to twice the tension of the cable 300. When the cable is paid out and the instrumentation rail is accelerated down, the force experienced by the tension spring 520 is less than twice the tension of the cable 300. When the cable is folded and the boom is lifted up, the force applied to the tension spring 520 is greater than twice the tension of the cable 300.

The offshore buoy can swing along with waves at sea, and the tight state of the cable 300 can be influenced by the heaving of the buoy in the swinging process of the buoy, and the loose cable 300 is easy to block when being folded, so that the influence of the heaving force of the buoy on the cable 300 is reduced by adopting the tension spring 520 or the tension spring 520 to be matched with the tension sensor, and the cable 300 is always kept in the tight state.

The profile lifting system further comprises a wire arranging device 600 and a transmission member 700, wherein the wire arranging device 600 is used for arranging and gathering the cables 300, and the wire arranging device 600 is connected with the wire winding roller 200 through the transmission member 700. Through the connection of the transmission member 700, the wire arranger 600 is driven to move along with the rotation of the wire winding drum 200, so that the cable 300 is not messed when being folded or unfolded, and the cable 300 is in a proper position in the wire winding drum 200.

The driving member 700 of the profile lifting system comprises a first sprocket 710, a chain 730 and a second sprocket 720. The first chain wheel 710 is connected with the wire winding drum 200, for example, the rotating shaft of the first chain wheel 710 and the rotating shaft of the wire winding drum 200 are the same, when the motor drives the wire winding drum 200 to rotate, the first chain wheel 710 rotates synchronously; or the rotating shaft of the wire winding roller 200 is in meshed transmission connection with the rotating shaft of the first chain wheel 710 through a pair of gears or gear boxes. The second chain wheel 720 is connected with the wire arranging device 600, for example, the second chain wheel 720 is fixedly connected with one end of the reciprocating screw 630 of the wire arranging device 600, or the rotating shaft of the first chain wheel 710 is in meshing transmission connection with the reciprocating screw 630 through a pair of gears or gear boxes. The first sprocket 710 and the second sprocket 720 are drivingly connected by a chain 730. When the motor drives the winding drum 200 to rotate, the first chain wheel 710 rotates synchronously, and the chain 730 drives the second chain wheel 720 to rotate, so that the wire arranging device 600 moves, and the wire arrangement of the cable 300 is convenient to gather.

To facilitate the transmission of the chain 730, the first sprocket 710 has the same module as the second sprocket 720. When the number of teeth of the first sprocket 710 is the same as that of the second sprocket 720, the angular speeds of the two rotations are also the same. When the number of teeth of the first sprocket 710 is less than that of the second sprocket 720, the outer diameter of the first sprocket 710 is less than that of the second sprocket 720, and since the chain 730 travels over the same length on the first sprocket 710 and the second sprocket 720, the angular velocity of the first sprocket 710 is greater than that of the second sprocket 720, that is, the sprocket of the wire arranger 600 has to rotate at a slower speed, which makes the cable 300 get closer on the wire winding drum 200 due to the movement of the wire arranger 600.

The wire arranging device 600 comprises a pulley 610, a wire arranging frame 620, a reciprocating screw 630, a limiting shaft 640 and a base 650, wherein the base 650 is fixedly connected to the external frame 400, the pulley 610 is arranged on the wire arranging frame 620, the reciprocating screw 630 is connected with the base 650 through a bearing, two ends of the limiting shaft 640 are fixedly connected with the base 650, or two ends of the limiting shaft 640 can also be fixedly connected to the external frame 400; the reciprocating screw 630 is arranged in parallel with the limit shaft 640. The wire arrangement frame 620 is sleeved on the reciprocating screw rod 630 and the limiting shaft 640, a through hole matched with the limiting shaft 640 is formed in the wire arrangement frame 620, a threaded hole matched with the reciprocating screw rod 630 is formed in the wire arrangement frame 620, and the wire arrangement frame 620 is in threaded connection with the reciprocating screw rod 630. One end of the reciprocating screw 630 is connected with the second chain wheel 720, the reciprocating screw 630 is in a reciprocating thread type, and the thread forms in two spiral directions are rectangular or trapezoidal. When the motor drives the winding drum 200 to rotate, the first chain wheel 710 rotates along with the winding drum, and the chain 730 drives the second chain wheel 720 to rotate together, so that the reciprocating screw 630 is driven to rotate; when the reciprocating screw 630 rotates, due to the limiting effect of the limiting shaft 640, the creel stand 620 matched with the reciprocating screw 630 makes reciprocating motion on the reciprocating screw 630, so that the cables 300 can be uniformly wound on the winding drum 200 back and forth, and the cables can be reasonably wound.

The profile lifting system further comprises a wire presser 900, the wire presser 900 being hinged to the top of the outer frame 400, a spring being provided at the hinge of the wire presser 900 for pressing the wire presser 900 to the groove of the winding drum 200, and the wire 300 being pressed by the wire presser 900 to the winding drum 200 for preventing the wire 300 from being laterally deviated. Longitudinal restraint is applied to the cable 300, and abnormal conditions that the cable 300 is folded due to transverse deviation caused by excessive longitudinal freedom degree of the cable 300 are prevented.

The position that wire presser 900 and cable 300 contact can be with the optical axis of the recess of spiral cylinder 200 with wide, also can overlap on the optical axis of wire presser 900 and establish a sleeve, this sleeve can freely rotate on the optical axis, like this when wire presser 900 goes up the sleeve and is pressing cable 300, along with the drawing in of cable 300, the sleeve rotates on the optical axis, sliding friction becomes rolling friction, frictional force between cable 300 and wire presser 900 becomes littleer like this, prevent that wire presser 900 from producing wearing and tearing to cable 300, produce fine abrasionproof and decrease effect.

The cable 300 of the profile lifting system can be a steel wire cable wrapped with a rubber layer, has good strength, is not easy to deform and break, and simultaneously avoids the corrosion of seawater. Preferably, the cable 300 includes a cable, one end of the cable 300 is electrically connected to the monitoring device in the device housing 100, from the end of the device housing 100, the cable 300 sequentially passes through the pulley 540 of the cable tensioning device 500, the pulley 610 of the wire arranger 600, the wire pressing device 900, the surface wire hole in the groove of the wire winding drum 200, and the inside of the wire winding drum 200, the cable 300 is electrically connected to the conductive slip ring inside the wire winding drum 200, and the conductive slip ring is electrically connected to the collecting device.

The inside of the winding drum 200 is a closed cavity, which has a good waterproof function, and is suitable for the electrical connection of relevant instruments in the marine environment, and the conductive slip ring can be arranged inside the winding drum 200. The motor for driving the winding roll 200 to rotate may be disposed inside the winding roll 200, or may be disposed outside the winding roll 200, so that a waterproof measure is taken.

The motor may be disposed inside the winding roll 200, and drives the winding roll 200 to rotate by engagement of the driving gear with the rotation shaft of the winding roll 200. The inside of the winding roll 200 can be conveniently made into a cavity with good waterproof performance, and the components related to the electrical connection can be arranged inside the winding roll 200. The motor can be controlled by the control circuit, and the rotation of the motor can be controlled in a remote control mode; or the offshore buoy can send and receive radio signals, and related operations of the monitoring instrument are remotely realized through the radio signals, for example, the monitoring instrument is lowered to a certain depth in seawater for monitoring; the related data measured by the monitoring instrument is remotely transmitted to the user, and the user can obtain the related monitoring data in real time and obtain the first-hand data.

The conductive slip ring is an electronic component which is connected to a rotating body by special equipment to transmit energy and signals, and consists of a rotating part and a static part, wherein the rotating part uses a rotating structure of the equipment and operates together with the rotating structure, and is called a rotor; the stationary part is connected to the stationary structure of the device and is called the stator. The cable 300 rotates with the take-up drum 200 while the cable 300 is also electrically connected to the conductive slip ring. Due to the formation of the channels between the stator and the rotor, there must be a contact between them, which is a functional part of the whole conductive slip ring, which is a carrier of various properties. Therefore, a stable and reliable rotary connection system (matching material selection, reasonable design and precise production of parts) is formed, and the required signals can be transmitted through the rotation of the two ends of the slip ring. The principle of operation of conductive slip rings is that in order to maintain electrical contact between two electrical circuits on two structures with relative motion, some type of sliding contact may be used to connect the circuits.

The outer surface of the cable 300 can be provided with scales so as to clearly know how deep the monitoring instrument is lowered to the sea surface in real time, and how long the cable 300 is correspondingly lowered for monitoring the environment deep below the sea surface, which is relatively simple and convenient.

The motor driving the winding drum 200 to rotate may be a stepping motor, and the descending distance of the monitoring instrument may be precisely controlled by controlling the rotation of the stepping motor, for example, the transmission ratio may be designed in advance, and the number of revolutions of the stepping motor corresponding to the descending of the monitoring instrument may be designed, so that how deep the monitoring instrument is descended below the sea surface may be intelligently controlled. The intelligent control can also be carried out by adopting a form searching mode, a field verification mode is adopted, the stepping motor rotates too many circles when the monitoring instrument descends by one meter, and a search form is correspondingly established. And the depth of the monitoring instrument carried by the offshore buoy under the sea surface can be remotely controlled by sending and receiving radio signals.

The profile lifting system further comprises an instrumentation bar fixture 800, the instrumentation bar fixture 800 being disposed on the outer frame 400 for holding the instrumentation bar 100 in place when the instrumentation bar 100 is lifted up.

The bottom end of the long rod 120 may be detachably coupled to the bottom connection member 130. When the bottom end of the elongated rod 120 is disengaged from the bottom attachment member 130, the elongated rod 120 may be rotated open to position the monitoring instrument in the instrument bar 100 defined by the plurality of elongated rods 120. The long rod 120 of the instrument fence 100 not only serves to fix the monitoring instrument, but also serves to protect the monitoring instrument, thereby preventing the monitoring instrument from being damaged by large fish or being damaged by external objects.

The outer side of the long rod 120 of the instrument bar 100 is provided with a stop block 122, and the instrument bar fixing device 800 is in a hollow round table shape with a wide lower part and a narrow upper part; a small gap may be left in the truncated-cone-shaped sidewall of the instrumentation rail fixture 800 to allow the instrumentation rail fixture 800 to have a certain adjustability and be expanded a little to accommodate a slightly larger instrumentation rail.

When the instrumentation bar 100 is lifted to the instrumentation bar fixture 800, the stopper 122 abuts against the inner sidewall of the instrumentation bar fixture 800, so as to prevent the instrumentation bar 100 from being lifted all the time and colliding against the cable tensioner 500 and the outer frame 400, and simultaneously, since the stopper 122 abuts against the inner sidewall of the instrumentation bar fixture 800, the instrumentation bar 100 is prevented from being suspended by the cable 300 to swing greatly and from colliding against other parts on the offshore buoy.

The inner sidewall of the toolbar holder 800 may have a rigid flange, and the stop 122 of the toolbar 100 may be a resilient latch, and the stop of the toolbar 100 is normally in an extended state. When the tool crib 100 is lifted to a certain height so that the stopper of the tool crib 100 contacts the flange of the inner sidewall of the tool crib fixing device 800, the stopper 122 is compressed and contracted, and the stopper 122 can be expanded again through the flange, so that the tool crib 100 can be supported and fixed. When the instrumentation bar 100 is about to be removed from the flange and lowered into the sea, the instrumentation bar 100 may be first raised a distance to trigger the switch that retracts the stop 122 so that the instrumentation bar may be lowered smoothly to a depth into the sea.
