Regarding the aforementioned floating body queue, some of the floating bodies are the floating bodies of wave generators, and the front and back of the queue are buoys (not the floating bodies of the wave generator). The wave generator can adopt the anchor technology, which is briefly introduced. A hanging anchor is a gravity anchor suspended in the water. See patent application CN107255060A. Here is a brief introduction to the hanging anchor scheme, as follows:

Hanging in the water, the WECS floating body is in the middle of the two buoys;

The two ropeways are combined into one strand on the left side of the gravity anchor and go around a pulley. The pulley frame and the left side of the pulley are used for suspending gravity. The cable connection of the anchor is also the same on the right side, symmetrical. Pulleys on both sides equally divide the pulling force of the buoy on the cable into the two ropeways, and the two ropeways provide upward pulling force to the pulleys that pass through and are installed at the apex of the gravity anchor, thereby suspending the gravity anchor in the water.

At both ends of the frame, the bottom end of the V-shaped rope is connected to the suspension rope. The suspension cables on both sides provide upward pulling force to the two rigid straight rods, and the rigid straight rods give upward lifting force to the gravity anchor. Similar to a stretcher, the gravity anchor can slide left and right with the rigid straight rod as a guide rail.

The above is the solution X2-4-3 -1. The connection between a certain end of the cross/bell-shaped cover/ball seat and the buoy is preferably an active connection.

Or the circuit connector is a rotary type, and the middle part of the outer tube is fixedly connected with one end of a straight connecting rod to form a T-shaped structure. The connecting rod is a conductor and is electrically connected to the outer tube. The bottom end) serves as the first mechanical & circuit connection point between the circuit connector and the outside, connecting the rope and the single-core cable (a part of the circuit) on one side of the buoy; the inner tube of the circuit connector The two ends of the first U-shaped frame are respectively fixed in the holes at the left and right ends of a first U-shaped frame.

For scheme X, scheme X2-5 is preferred: the floating body queue is arranged in a circular (such as a clock scale) queue; in order to maintain the circular shape, some of the floating bodies are moored with anchors, and there are multiple (≥3) in the queue The floating body of the wave generator, the generators of the wave generators are all direct current generators, or alternating current generators whose output is rectified, and the positive and negative output circuits of the generators float from floating in two opposite directions, respectively. The drill is drawn out from the body and continues to extend along the rope in respective directions. The generators of the wave generators are connected in series through the circuit in the sequence of the queue, but the generators of the first and last wave generators are connected in series. Without direct connection, a total power supply is formed, and the output voltage is equal to the sum of the voltages of the generators.

The advantages of this solution are: the circuit can adopt a single-core cable, the energy collection is simple, the voltage is automatically boosted, and the cost is low.

Stretching, and when seawater impacts the cable, the rope can provide supporting force to prevent the cable from being broken. The rotating/universal/spherical joint circuit connector passing through the cable extension avoids the breakage caused by the frequent bending of the cable; and the circular array series scheme of the wave generator allows the electric energy of multiple generators to be single The core cable collection eliminates the need for a booster station, and the cost is low.

Detailed ways

The following further description is provided in conjunction with the accompanying drawings. All the embodiments here are intended to help understand the representative examples of the present invention, and are not the only form, and are not intended to limit the protection scope of the present invention.

Section I: Power transmission scheme based on water surface floating body queue

Since the schemes X-1, 2, 3, 4, and 5 are similar to X2-1, 2, 3, 4, and 5, only specific examples of the X2 series of power transmission schemes based on the water surface floating body queue are introduced here.

Scheme X: There is a row of floating bodies on the sea. The floating bodies at the beginning and the end of the queue are moored. In the queue, adjacent floating bodies are connected by ropes, that is to say, the entire row of floating bodies is connected in series by multiple ropes; Among them, some floating bodies are the floating bodies of wave generators. After the electric circuits drawn by the generators of the wave generators are drilled out of the floating bodies, they are attached to the rope and extend along it.

For scheme X, it is preferred: see Figure 2. The cable 12 initiated from the WECS generator is drilled out of the floating bodies B and D, and then attached to the rope 44 to extend; this circuit goes from the left to the right of the figure, two generators In series. There are three types of attachments: 1) The cable on the right side of the floating body is tied to the rope by a number of spaced apart strings, one end of the string is tied to the cable, the other end is tied to the rope, two The cable length between adjacent strings is longer than the rope; 2) the cable 12 on the right side of the floating body B is spirally wound on the rope 44; 3) the left side of the floating body B is the spiral cable 121 sheathed on the rope 44.

Principle: Since the rope between the floating bodies will expand and contract under pulsed tension, the two ends of the cable 12 must be able to adapt to this expansion, and the spiral cable can meet this requirement. For the other two, the cable should also be loose. In addition, when seawater impacts the cable 12, the rope 44 can provide a supporting force for the cable 12 to prevent it from being broken by bending.

For the power transmission scheme X, it is preferable: as shown in Figure 2 floating body B, the circuit passes through the universal joint/spherical joint circuit connector at the point where the floating body is drilled out; see Figure 3: as a part of the circuit, by The single-core cable 12 from the generator G is connected to the A terminal of a universal joint circuit connector 151, and the A terminal is fixed on the floating body shell 152 (if the floating body shell is conductive, the A terminal should be insulated from the floating body shell Processing), and the other end B of the universal joint circuit connector is connected to one end of a single-core cable 12 extending along the rope 44.

Principle: The floating body B fluctuates with the waves on the seashore, causing the rope 44 connected to it to swing relatively. If the output cable of the generator is simply drilled and extended from the floating body shell, it will soon be caused by frequent Bending causes fracture. With the universal connection characteristics of the universal joint circuit connector 151 in this solution, the bending movement of the cable 12 can be eliminated, thereby protecting the cable.

Preferably, the circuit connector 151 and the connection between the circuit connector 151 and the cable 12 are sealed on the floating housing 152 with a hemispherical flexible insulating cover 150 to prevent it from contacting seawater, and the cable 12 connected to the B end is removed from the flexible insulating cover Drill in the hole on the top and seal the hole. It is further preferred that the rope 44 is connected to the B end through an insulating connecting rod 153.

Principle: The rope 44 and the end of the cable 12 are connected at the same position, which avoids the relative movement of the rope and the cable, and improves the reliability. In addition, the insulating connecting rod 153 passes through the hole on the insulating cover 150, and the hole needs to be sealed.

For the power transmission scheme X, it is preferable: see Figure 2 at the weight 51 between the floating body D and the buoy C, and the circuit extends through the ball hinge circuit connector 149 at the weight tied in the middle of the rope 44, Look again at Figure 4: In the middle of the rope 44 between a certain floating body, a weight 51 is connected by a short rope 49. Due to the weight of the weight, the connection point between the short rope 49 and the rope 44 is the tie point, The rope 44 will have an included angle of <180°; the A end of a spherical hinge circuit connector is fixed on the rope 44 on the left side of the tie point by a fixing frame 154, and is connected to a section of single core on the left side. The other end B of the cable 12 (a part of the circuit) is fixed to the rope 44 on the right side of the tie point by another fixing frame 154, and is connected to a section of the single-core cable 12 on the right side (the circuit Part of); through the tie point and perpendicular to the plane on which the ropes on both sides of the tie point are located to make a straight line OO', the straight line coincides with the center of the spherical hinge circuit connector 149.

Principle: The rope 44, the fixing frame 154, and the A/B end on both sides of the tie point are like on both sides of a virtual hinge. The elements on both sides can rotate relative to each other around 00'. In the real sea conditions, the angle of the rope 44 is constant. The change, the ball hinge circuit connector is driven by the fixing frame 154 to make corresponding changes. During this process, the cable 12 will not be stressed and will not move relative to the rope 44 on the same side, thereby avoiding the cable 12 from bending and swinging.

Preferably, a flexible insulating sleeve 150 is used to wrap and seal the spherical hinge circuit connector 149 and the connection with the cable to prevent contact with seawater and prevent electric leakage. The fixing frame 154 is insulated, and the fixing frame, The cable 12 needs to be sealed at the hole drilled from the flexible insulating sleeve 150.

For the power transmission scheme X, it is preferable: as shown in FIG. 2, a weight 51 is provided in the middle of the rope 44 between the buoy A and the buoy B, and the circuit extends through the rotary circuit connector 148 at the weight while extending. Here it can be understood that the rope 44 is disconnected, and the two end points formed after the disconnection are respectively connected to the two ends of the rotary circuit connector through the insulating connecting rod 153. Please see Figure 5, the lower right corner of the figure is the rotary circuit connection The structure diagram of the device + connecting rod + first U-shaped frame + mandrel + second U-shaped frame, the two ends of the inner tube are fixed in the holes at both ends of the U-shaped frame A, and the outside of the middle part of the U-shaped frame A is used as the first The mechanical & electrical connection point connects the rope 44 and the single-core cable 12 on the left; the inner tube is fixed with a connecting rod B in the middle of the outer tube, and the connecting rod B is perpendicular to the axis of the outer tube, forming T-shaped, the end of the connecting rod B is used as the second mechanical & circuit connection point to connect the rope 44 and the single-core cable 12 on the right; the two ends of the mandrel 159 in the inner tube are fixed on the two ends of the U-shaped frame C In the hole, the outside of the middle of the U-shaped frame C is used as a third mechanical connection point to be connected to a weight 51 through an insulating connecting rod 153. The U-shaped frame at end A and the connecting rod B are both conductors, and the current can flow from one end to the other.

Principle: Under the impact of sea water and sea breeze in real sea conditions, the distance between the floating bodies mentioned in Scheme X often changes, resulting in frequent changes in the angle between the ropes 44 on both sides, and the angle between the two ends of the rotary circuit connector also follows. Variety. The rotary circuit connector 148 is responsible for the circuit connection and the connection of the rope at the same time. Its two ends follow the rope 44 to swing accordingly while maintaining the circuit connection. The cable 12 on each side and the rope 44 on that side do not move relative to each other. The damage caused by frequent bending of the cable 12 is avoided.

Preferably (see FIG. 5): the circuit connector 148, the conductive U-shaped frame A and the connecting rod B are sealed with a flexible insulating sleeve 150 (such as a rubber sleeve) to isolate the seawater and prevent electric leakage. The insulating connecting rod 153 connected by the rope 44 passes through the hole of the flexible insulating sleeve 150, and the hole needs to be sealed. The other end of the insulating connecting rod 153 is connected to the end of the connecting rod B/outside the middle of the U-shaped frame A . The weight is located outside the flexible insulating sleeve, and the weight is connected to one end of an insulating connecting rod 153. The other end of the insulating connecting rod is drilled into the hole on the flexible insulating sleeve 150 and connected to the U Frame C, the hole should be sealed and waterproof.

For scheme X, it is preferable that one of the floating bodies is not a floating body of a wave generator, and is named a buoy here (A, C, E in Figure 2), and there are three ways for the circuit to pass through the buoy. kind:

1) As shown in Figure 2, a universal joint circuit connector 151 is installed on the left and right sides of the buoy C; the installation method of the circuit connectors on the left and right sides is the same as that in Figure 3, except that the generator G is replaced with a single core The cable (the dotted line in buoy C in Figure 2) connects the A ends of the two circuit connectors on the left and right sides.

Principle: The buoy C bumps in the waves, the rope 44 on the left and right sides swings relative to the buoy C, and the cable 12 on the rope 44 also swings accordingly. With the help of the universal connection feature of the circuit connector 151, the buoy The inner cable of C can be connected with the outer cable of buoy C in 120,000 directions, thereby avoiding the damage caused by the bending of the cable.

Preferably (refer to Figure 3): the circuit connector 151 and its connection with the single-core cable 12 are sealed on the shell of the buoy C with a hemispherical flexible insulating cover 150 to avoid contact with seawater, connect to B The cable at the end is drilled into the hole on the flexible insulating cover, and the hole should be sealed; on the left side of the buoy C in Figure 2, the rope 44 is connected to the buoy C through an insulating connecting rod 153, details Refer to Fig. 3: One end of the rope 44 and the insulating connecting rod 153 is connected outside the hemispherical flexible insulating cover 150, and the other end of the insulating connecting rod 153 is drilled into the hole on the insulating cover 150, And connect with the B end of the circuit connector, and the hole should be sealed. The effect of this is that both the left side rope 44 and the left side cable 12 are connected to the B end of the left circuit connector, which avoids the relative movement of the rope 44 and the cable 12, thereby improving reliability.

2) At buoy E in Fig. 2, the rope is connected in parallel with the circuit connector. For details, please refer to Fig. 4, but the weight 51 in Fig. 4 needs to be assumed as a buoy, and Fig. 4 is turned upside down. The ends of the ropes 44 on the left and right sides of the buoy E are connected together. The connection point O is named as the tie point. The bottom of the buoy E is connected to the tie point O; due to the buoyancy of the buoy, the tie point O is left and right. The ropes on both sides will have an included angle of <180°; the arm 156 of the A end of the ball-hinge circuit connector 149 is fixed to the rope 44 on the left side of the tie point through a fixing frame 154, and is connected to the left side A section of single-core cable 12, its B-end arm is fixed to the rope 44 on the right side of the tie point through another fixing frame, and is connected to a section of single-core cable 12 on the right side; passes through the tie point O and Draw a straight line perpendicular to the plane where the ropes 44 on both sides of the tie point are located, and the straight line should coincide with the center of the spherical hinge circuit connector 149.

Principle: With the aid of the universal connection feature of the ball hinge circuit connector 154, the cables 12 on both sides of the tie point are connected. The cables 12, the fixing frame 154, and the rope 44 on both sides of the tie point are like being on both sides of a virtual hinge. The shaft of the hinge is on OO'. The cables 12, the fixing frame 154, and the rope 44 on each hinge are , No relative movement occurs, thereby avoiding bending damage to the cable 12 when the rope 44 swings.

Preferably, a flexible insulating sleeve 150 is used to wrap and seal the circuit connector 149 and the connection with the cable to prevent water leakage and current leakage. The fixing frame 154 is insulated, and the fixing frame 154, The cable 12 needs to be sealed at the hole drilled from the flexible insulating sleeve.

3) At buoy A in Fig. 2, the rotary circuit connector 148 is connected in series in the rope 44. Please refer to Fig. 5 for details, but imagine the weight 51 in Fig. 5 as a buoy 59, and refer to Fig. 5. Flip up and down.

Principle: In this example, the circuit connector is connected to both the rope and the cable. The buoy A fluctuates with waves on the sea, and the angle between the ropes 44 on both sides often changes. For the cables 12 attached to the ropes, if the cables on both sides are directly connected, they must be broken due to frequent bending and rotation. After the modular circuit connector 148, the angle change of the cables 12 on both sides is completely completed by the circuit connector 148, and the cables 12 and the rope 44 on each side will not move relative to each other, thereby protecting the cables.

Preferably, a flexible insulating sleeve 150 (such as a rubber sleeve) is used to seal the circuit connector 148 and its conductive U-shaped frame A and connecting rod B to isolate the seawater and prevent electric leakage. The buoy A is located outside the flexible insulating sleeve 150 (see FIG. 2), the connected insulating connecting rod 153 is drilled from the hole on the flexible insulating sleeve 150, and the other end of the insulating connecting rod is connected to the core On the U-shaped frame C to which the shaft 159 is fixed, the hole must be sealed and waterproof.

For scheme X, it is preferable that: see Figure 6, the floating bodies are arranged in a circular (for example, clock numbers) queue; in order to maintain the circular shape, part of the floating bodies are moored by the ground anchor 46 (star) in the queue A floating body with multiple wave generators. The generators G of the wave generators are all DC generators/alternators whose output is rectified. In the sequence of the queue, all the wave generators are passed through the circuit (dotted line) Connected in series, but there is no direct electrical connection between the first generator G1 and the last generator G5 to form a total power source. The output voltage at the open loop is equal to the sum of the voltages of the generators. The advantages of this scheme are: a single-core cable can be used, energy collection is simple, a booster station is eliminated, and the cost is low. In this embodiment, it is preferable that when the circuit extends along the rope 44 (black solid line), solution X2-1 is adopted, and solution X2-2 is adopted for the circuit from the generator to the floating body. When passing the heavy block (black square) tied in the middle of the rope, the solution X2-3 is adopted, and when the circuit passes the buoy (hexagon), the solution X2-4 is adopted.

Section II: The anchor technology has been introduced in CN107255060A, and there are the following types:

1) Directly connected hanging anchor: see figure 1, mooring a buoy A, C on each side of the floating body B, each buoy is tied to a cable 57, the other end of the two cables is connected to the gravity anchor of the WECS 17 on; the gravity anchor 17 below the floating body D in Figure 2 is also a directly connected hanging anchor.

2) Pulley anchor: see Figure 1. A buoy 59 is moored on each side of the floating body D. The two ends of a cable 57 are tied to the two buoys 59. The pulley 56 of the anchor 17, and the bottom end of the pulley frame of the pulley 56 is connected to the top surface of the gravity anchor 17 of WECS, and the energy collection cable 30 that was originally to be connected to the gravity anchor 17 from above is connected to the top of the pulley frame 56 instead, The gravity anchor below the WECS floating body G and the gravity anchor below the WECS floating body B in Figure 2 are both pulley anchors.

3) Double ropeway anchor: The gravity anchor is a flat cube, and the top four vertices of the gravity anchor are respectively equipped with a pulley, so that there are two pulleys on the two opposite sides of the top surface of the gravity anchor, and the pulleys (two) on each opposite side are in each A ropeway rolls, the two ropeways merge into one strand on the left side of the gravity anchor and wind around a pulley. The pulley frame of the pulley is connected with the cable used for suspending the gravity anchor on the left side. The same is true on the right side, symmetrical. . Pulleys on both sides equally divide the pulling force of the buoy on the cable into the two ropeways, and the two ropeways provide upward pulling force to the pulleys installed on both sides of the gravity anchor through which the gravity anchor is suspended in the water.

4) Side winding anchor: The gravity anchor is a flat cube. A fairlead is installed on the front and back of the gravity anchor. Two guide pulleys are installed on the two vertical edges of the right side of the gravity anchor. The cable passes through the rear guide in turn. The cable guide, the guide pulley that bypasses the right rear edge, the guide pulley of the right front edge, and the front fairlead pass through. The two fairleads and the two guide pulleys are at the same distance from the top surface of the gravity anchor. The suspension cable is equivalent to bypassing one side of the gravity anchor, and the force application point is on the fairleads on both sides. Obviously, with the help of fairleads and guide pulleys, the gravity anchor can slide along the cable.

5) Stretcher anchors: Two straight rigid rods are parallel and aligned with their ends respectively passing through the gravity anchor and two transverse through holes separated by a certain distance. The left ends of the two rigid straight rods are fixed to a steel frame, and the right ends of the two rigid straight rods It is fixedly connected to another steel frame, and the suspension cables on both sides are connected to the steel frames on both sides by V-shaped ropes, that is, the two vertices of the V-shaped ropes are connected to the two ends of the steel frame, and the bottom ends of the V-shaped ropes are connected to the suspension cables. . The suspension cables on both sides provide upward pulling force to the two rigid straight rods, and the rigid straight rods give upward lifting force to the gravity anchor, similar to a stretcher. The gravity anchor can slide left and right with a hard straight rod as a guide rail.

In the above 3), 4), and 5) three kinds of anchoring schemes, the other ends of the suspension cables on both sides of the gravity anchor are connected to two buoys moored at a certain distance on the water surface, and the floating body of the wave generator is in the two buoys. In the middle of the buoy, this is the same as 1) and 2). For the above five anchoring schemes, the wet weight of the gravity anchor (gravity minus the buoyancy) is greater than the upward pulling force of the WECS when doing work, and the maximum buoyancy provided by the two buoys is greater than the wet weight of the gravity anchor, and it is best to have sufficient redundancy Reserve buoyancy.

Preferably: in the above various anchoring solutions, the floating body and the buoy are connected by a rope 44 (as shown in Figures 1 and 2). In this way, they are mutually involved as a whole, and when the floating body moves, it will be pulled by the buoys on both sides, so as to prevent the floating body from deviating too much. So as to prevent the movement of the gravity anchor below the floating body from reaching the limit. It is further preferred that a weight 51 is tied in the middle of the rope 44 to provide cushioning.

The above is the anchoring plan. For WECS's pre-tightening hydraulic system, if the suspended gravity anchor, which is a reference for relative underwater movement, is unstable, it will not be conducive to the WECS's pre-tightening hydraulic system's MCU to better judge the working status of WECS, because The relative motion in which both the WECS floating body and the gravity anchor are moving is more complicated than the relative motion in which only the WECS floating body is moving and the gravity anchor is stable. For example, sometimes the floating body is falling with the waves and the gravity anchor is falling at a faster speed. At this time, the floating body actually rises relative to the gravity anchor, and the hydraulic cylinder is in a working state. At this time, it is difficult for the MCU to determine which state the WECS is in, so it is necessary to keep the suspension anchor (the suspended gravity anchor) as stable as possible , The following are three specific measures for the improvement of anchoring technology.

For the hanging anchor scheme, it is preferable: as shown in Figure 2, the buoys (A, C, E) are in the shape of a slender capsule, and the connection point of the buoy is located on the outer center point of one end of the capsule. For the slender capsule shape and flat buoy of the same volume, the buoyancy change caused by the ups and downs of waves must be small in the former. This makes the anchor more stable.

Preferably (see Fig. 1): a horizontal damping plate 97 is fixed at the bottom of the gravity anchor 17 in the suspension anchor system, and the gravity anchor is located above the center of the damping plate. The function is to use the resistance of the water encountered by the damping plate to move in the water to make the gravity anchor relatively stable in the vertical direction.

Preferably, the middle part of the cable 57 suspending the gravity anchor 17 is replaced with the second tension spring 104 (as shown in Figures 1 and 2). The suspended buoys can be asynchronous, and the spring acts as a buffer. Supplement: If the suspension cable itself has good elasticity, such as nylon rope, it can also be equivalent to adding a spring.

In the case of only the damping plate 97 without the second tension spring 104 on the suspension cable for buffering, if the suspension cable 59 is too rigid, then the movement of the gravity anchor with the damping plate will be subjected to huge resistance from water. The buoy will be impacted by waves on the sea surface, which will cause a very large impact force on the suspension cable. To solve this problem, it is further preferred: the anchor technology uses the aforementioned second tension spring and damping plate at the same time. , This can greatly reduce the impact force on the suspension cable.

Section III: Wave generator using wave buoyancy to do work in one direction

The wave generator that uses wave buoyancy to do work in one direction is introduced below. It uses wave buoyancy to generate power when the wave rises, and resets when the wave falls. The core is the wave energy collection and conversion system, that is, the Wave Energy Convert System, referred to as WECS (not Including rope control device), which includes sea surface components, energy harvesting cables 30, and underwater relative motion reference objects (such as gravity anchor 17/hanging anchor/vacuum suction anchor/pile). The sea surface component refers to the wave generator close to the sea surface That part is the part that converts relative motion into electrical energy, including the floating body, components that move relative to the floating body, hydraulic systems, and generators. The components that move relative to the floating body use energy cables and the underwater relative motion reference object Connect, or through the energy cable 30 of the rope control device 79.

The inverted L type WECS, to be precise, belongs to the single floating body pressure difference type B, as shown in Figure 7, including the floating body 1, the inverted L rigid frame 19, the closed hydraulic system, and the upper and lower fairleads 11 acting as guide rails. The structure of the floating body 1 is a fully enclosed hollow shell with a cylindrical shape with a through hole on the axis, and the rotation section of the axis is a rectangle; an inverted L rigid frame 19 with a tube section, and its vertical side is spaced from the upper and lower sides. The four-roller fairlead 11 of the distance passes through, the upper fairlead is installed at the upper end of the through hole, the lower fairlead is installed at the bottom of the straight tube 63, the straight tube 63 is upright, and the top end is fixed At the bottom of the floating body, the inner diameter of the straight cylinder 63 is larger (or less than or equal to) the through hole on the floating body, and the central axis coincides with the through hole axis of the floating body; the four sides of the vertical side of the inverted L rigid frame are respectively The four rollers of the two fairleads are in close contact with the four rollers one by one. The fairlead functions as a guide rail that guides the up and down movement of the inverted L rigid frame 19. The straight tube 63 here is equivalent to the bracket, of course, there is no straight tube 63, and the lower fairlead 11 is installed at the bottom of the through hole of the floating body 1.

The end of the horizontal side of the inverted L rigid frame 19 is connected to the end of the plunger rod 3 of a vertical plunger cylinder, which can be fixed/hinge/earring. The rear end of the plunger cylinder 138 is connected to the top surface of the floating body 1. The connection can be fixed connection/hinge axis/earring. Of course, the plunger cylinder 138 can also be inverted and connected to the end of the horizontal side of the inverted L rigid frame and the top surface of the floating body 1; the plunger cylinder 138 can also have a certain inclination It is best to be in the plane where the inverted L rigid frame is located; the effect is: when the inverted L rigid frame presses the hydraulic cylinder, the pressure in the hydraulic cylinder can be driven higher at the end of the work than the initial stage, because with the inverted L rigid frame The drop of the plunger cylinder 138 will increase the inclination of the plunger cylinder 138, and the component force required to compress the plunger cylinder 138 in the vertical direction is reduced, which is beneficial to make full use of the remaining net buoyancy of the floating body 1 when the wave rises. Of course, for the inclined installation of the plunger cylinder 138, the connection between the inverted L rigid frame and the top of the floating body 1 cannot be fixed.

Preferably: the bottom end of the inverted L rigid frame 19 is connected to the casing of the rope control mechanism 79, and the universal connection 84 is adopted. The advantage is that the casing of the rope control mechanism 79 can swing with the swing of the energy cable 30, which can reduce The pressure of the fairlead 11 of the rope 30 on the rope control mechanism 79, when the rope 30 swings along the axial direction of the pair of rollers at the bottom of the rope guide, by means of the following movement of the rope control mechanism 79 It can greatly reduce the wear of the energy cable 30 on the fairlead 11. Preferably, the flexible/universal connection is a cross universal joint/double lock ring connection, which can prevent the rotation of the rope control mechanism 79 and avoid the use of The entanglement of the energy cable and the reset cable.

Preferably: the limit block 106 is fixed on the upper part of the vertical side of the inverted L rigid frame. When the plunger rod 3 moves downward and approaches the bottom of the plunger cylinder 138, the limit block 106 first collides with the top surface of the floating body 1 to protect the plunger. Cylinder 138.

The hydraulic system is a closed cycle, and the circulation route is the plunger cylinder cavity, the quasi-out check valve, the high-pressure accumulator, the hydraulic motor, the low-pressure accumulator, the access check valve, and the plunger-cylinder cavity. The motor drives the generator to generate electricity; the hydraulic pipe connected to the oil inlet and outlet at the bottom end of the plunger cylinder 138 is drilled from the top cover of the floating body, and the drilled hole needs to be sealed. The generator and the hydraulic system except the plunger cylinder are in Floating body cavity.

Principle: The principle is basically the same as the aforementioned single floating body pressure difference reset B type. When the hydraulic cylinder 138 does not exceed the stroke and does not trigger the rope control device, the floating body 1 fluctuates with the waves, and the bottom end of the inverted L rigid frame is connected to the The length of the rope 30 between the gravity anchors is locked, so the maximum height of the top of the plunger rod 3 is also locked, and the bottom end of the plunger cylinder 138 moves up and down with the floating body 1. When the floating body 1 rises, the plunger cylinder 138 It is compressed to output high-pressure hydraulic oil. Because the access check valve cannot go through, the hydraulic oil can only reach the high-pressure accumulator through the check-out valve (compared to the plunger cylinder). The pressure of the accumulator>the pressure of the low-pressure accumulator>atmospheric pressure. Under the action of the pressure difference between the high-pressure accumulator and the low-pressure accumulator, the hydraulic motor is driven to rotate to drive the generator to generate electricity, and the hydraulic oil also flows from the high-pressure accumulator To the low-pressure accumulator. When the floating body 1 falls, the pulling force of the energy cable 30 is rapidly reduced. At this time, the pressure in the plunger cylinder cavity is also rapidly reduced. At this time, under the action of the pressure difference between the low-pressure accumulator and the atmospheric pressure, the plunger is pushed up. Thus, the reset of the plunger cylinder is realized. Preferably: add oil filter 5.

Preferably, the plunger rod 3 is sheathed with a protective cover 10 (preferably made of soft rubber), one end of the protective cover 10 is butted and sealed with the plunger rod shaft, and the other end is butted and sealed with the outside of the plunger cylinder 108.

Preferably: the generator is a brushless permanent magnet generator; preferably: an overflow valve is connected in parallel beside the motor. Once the motor stops for some reason, the high-pressure oil of the high-pressure accumulator can pass through the overflow valve Enter the low-pressure accumulator to avoid excessive pressure in the high-pressure accumulator. Preferably, the motor is an axial piston motor with end face distribution.

Preferably, with regard to the oil supplement system: a cover is added to the top of the cylinder body of the plunger cylinder 138, and the cover and the top surface of the cylinder body form a sealed cavity for collecting and draining oil, and the plunger rod 3 is sealed from the top hole of the cavity The drain pipe 115 is led out from the sealed cavity, and then extends downwards, and is drilled into the cavity from the top cover of the floating body 1 (sealing treatment is required at the drilling site to not destroy the full sealing of the floating body), Finally enter a fuel tank.

Preferably: the electric charge pump 73 driven by the wave generator extracts hydraulic oil from the oil tank and injects it into the closed hydraulic circulation system; further preferably: a single-chip microcomputer and an auxiliary power supply circuit are added. According to the signal sent by the liquid level sensor 144 of the oil tank/the hydraulic pressure sensor on the closed-cycle hydraulic system, the electric charge pump 73 is started and stopped. When the liquid level sensor 144 detects that there is too much oil in the oil tank or the hydraulic pressure When the sensor detects that the pressure in the closed hydraulic circulation system is too low, the MCU will turn on the motor to drive the charge pump to pump oil from the oil tank into the closed hydraulic circulation.

Preferably: the cable 12 of the rope control device starts from the cavity of the floating body, drills upward from the top surface of the floating body (the outlet is to be sealed), and then becomes a spiral shape and extends upward, and finally a horizontal steel pipe 71 is drilled in, and the steel pipe 71 is inverted L The side of the rigid frame 19 is welded and the two cavities are connected. The cable 12 extends horizontally along the steel pipe 71, enters the vertical square tube of the inverted L rigid frame and extends downward, and finally drills out from the bottom side of the inverted L rigid frame , And finally enter the rope control rack cabinet 79. If the inverted L rigid frame 19 and the rope control mechanism casing 79 are fixedly connected, the cable 12 can directly enter the rope control frame casing from the bottom exit of the inverted L rigid frame, but the entrance must be sealed. Function: The spiral shape of the cable 12 part is to adapt to the change of the relative distance between the inverted L rigid frame and the top surface of the floating body. The cable 12 can be protected in the inverted L rigid frame square tube.
