Description

Floating body rope wheel wave power collecting device

Technical field

The present invention relates to a wave power collecting device, and more particularly to a wave energy collecting device that converts wave power into rotational power using a floating body, a rope, and a reel.

Background technique

Ocean wave energy is an endless renewable energy resource. How to use such abundant energy resources to serve human beings is an important topic that has been studied by predecessors and modern people. The use of wave energy to generate electricity is one of the major issues.

To use wave energy, first of all, there must be a wave energy collecting device. For the moment, the wave energy collecting device mainly has an oscillating water column, a pendulum plate, a rocker arm, a squat type using two floating body angle changes, and two in the vertical direction. The relative motion of the floating body oscillates the float and so on.

There is also a wave power collecting device that uses a floating body, a rope, and a reel as a wave power collecting device. The principle is that one end of a rope is attached to the anchor base, and the other end is wound on the reel of the floating body, in the floating body. When the wave rises, the distance between the floating body and the anchor base increases continuously, so that the rope is driven to rotate the reel, and the reel drives the downstream transmission system to drive the generator to run. When the floating body follows the wave, the distance between the floating body and the anchor base is continuously reduced. Because there is an overrunning clutch mechanism between the reel and the downstream drive system, the downstream drive system has a check pawl or the check valve of the hydraulic system cannot be reversed, so that the reverse force of the downstream drive mechanism cannot be reversed, so the reel and the reel The downstream transmission mechanism is disengaged, so that the reel only reverses the rope collection under the action of the rope collecting device. Patent application CN 101963125 A floating body based rope wheel wave power generation system, patent application CN 2099205U wave power generation original device belongs to this category, but these technical solutions are mainly about the transmission and conversion of wave energy, but for the collection part, it is only Conceptualized, principle-level, and does not give the specific structure of the collection device, without considering the complexity and the harshness of the sea state, it is still a short distance from the practical.

The chain barrel is hung under the floating body. One end of the chain is attached to the anchor base or the fixed platform, and the other end is stacked in the chain barrel through the guide wheel set, the guide chain wheel, the sprocket and the guide chain wheel; only one guiding wheel set is located below the center of the floating body. At the same time, the diagonal stays are symmetrically distributed at the center point. The reel drives the downstream drive train through an overrunning clutch connected to its shaft.

The invention has the following advantages:

1) The floating body, that is, the collecting part of the wave energy, and the outer casing of the whole device, are used in a single object, so that the cost is reduced, and all the core members are in the floating body cavity, which is easy to maintain. Because the floating wheel hangs the guide wheel set, the direction of the rope entering the reel is stable, and the rope is not inclined at a large angle, which increases the stability and reliability of the work. The guide wheel set is designed under the floating body so that the floating body has the ability to automatically correct when tilted. Because the diagonal tie rod is used, the force of the wave can be concentrated on the bracket of the guide wheel set through the diagonal tie rod, so that the floating body is not subjected to a very large bending moment, stress concentration is avoided, and the impact resistance of the floating body is enhanced, and at the same time When the floating body is tilted, the diagonal pull rod causes the guide wheel set bracket to bear only the pressure and is not bent by the overturning moment.

3) Only one guide wheel set is located below the center of the floating body. The diagonal tie rods are symmetrically distributed at the center point, which can balance the floating body. If one guide wheel set is placed at each end of the floating body, the center of the floating body will be subjected to bending moment.

4) A vertical tube is connected to the opening of the floating body to seal part of the air, thereby minimizing the intrusion of seawater into the sealing ring.

5) The main shaft is directly supported by the groove or convex wall. The bracket of the guide wheel set is directly connected with the groove or the convex wall, which makes the force transmission path the shortest, thus enhancing the reliability.

6) The tensioner on the diagonal tie rod makes the production process easy to adjust and easy to adjust after use. Figure 7) The guide wheel set uses two pairs of fixed pulley sets. The length of the lower part is longer than that of using only a pair of fixed sets of pulleys, so that the floating rope ropes are statically locked and submerged. Anchoring the long-throw hanging pipe vertical guide cable does not cause axial pressure on the lower pulley block.

detailed description

The invention does not relate to the transmission and power generation of the collected power, and is limited to the acquisition of wave power.

It is also possible to erect the diagonal pull rod on the bottom of the guide wheel set and the floating body, that is, one end of the diagonal pull rod is connected with the bottom keel of the floating body, and the other end is connected with the bottom end of the bracket of the guide wheel set. In addition, the rope can also be replaced by a chain. The reel is replaced by a sprocket. It also includes a guide sprocket, which is pressed at the place where the chain enters and exits the sprocket. The floating body is hung under the chain barrel. One end of the chain is attached to the anchor base or the fixed platform, and the other end is passed. The guide wheel set, the guide chain wheel, the sprocket and the guide chain wheel are stacked in the chain barrel; only one guide wheel set is located below the center of the floating body, and the diagonal tie rod is symmetrically distributed at the center point. The reel drives the downstream drive train through an overrunning clutch connected to its shaft. There are grooves or two convex hulls on the floating body shell, and both ends of the main shaft pass through the groove wall or two protrusions to enter the floating body cavity; optionally, a vertical tube is pressed under the groove or convex hull of the floating body shell, The vertical tube accommodates the groove or convex hull in the vertical direction. The groove wall or the convex wall is connected to the upper end of the bracket of the guide wheel set, and the main shaft has a groove wall or a convex wall as a bracket, and a bearing is sleeved at the sealing ring at the insertion hole. There is a tightener on the diagonal tie rod. The guide wheel set is two pairs of fixed pulleys placed axially perpendicular to each other, and the lower pair of fixed pulleys have a larger length; the reel can slide axially on the main shaft, and the retractable bellows on both sides of the reel, connecting the shaft and the coil The end of the barrel; the rope wound around the reel is sandwiched between the press roll and the rope groove of the reel, and the support of the press roll can slide on two guide rails or a single non-circular cross-section guide. The part of the rope that never wraps from the anchor base to the surface of the water is replaced by a chain. The bottom end of the chain is connected to the anchor base, the upper end is bound to the submerged float, the upper end of the chain has a hanging loop, and the lower end of the rope of the wave collecting unit is hooked. The chain can also be replaced by a long pole. A plurality of collecting devices are operated in series, and the floating body and the floating body are connected by a hanging ring or a cross universal joint shaft, and a hole is formed in the middle of the cross, and a hydraulic pipe or a wire, a communication cable, etc. pass through the middle. The following is further described in conjunction with the drawings.

6 and 8, the wave power collecting device comprises a floating body shell 1, a drum 3, an anchor base 57 or a fixed platform, a rope 2, and the floating body is a fully enclosed casing; the main shaft 4 of the drum passes through the floating body shell 1 The upper hole enters the floating body cavity, and has a sealing ring 43 at the penetration; and further comprises a rope collecting mechanism, a guiding wheel set 27 and a bracket 25 thereof;

Referring to Fig. 1, the guide wheel set is two tight grooved pulleys 80 (see Fig. 3), the rope 2 is sandwiched between them, and the guide wheel set 27 is fixed at a certain distance below the floating body, and is fixed to the floating body 1 by the bracket 25. Upper

See Fig. 8, the rope 2 - end is attached to the anchor base 57 or the fixed platform, and the other end is wound on the reel 3 through the guide wheel set 27; the reel 3 and the rope collecting mechanism are connected through the main shaft 4 shaft;

Here, the structure of the rope collecting mechanism is a worm spring 86 (see Fig. 6). One end of the worm is fixed on the main shaft, and the other end is fixed on the frame. The worm spring generates the same torque direction on the main shaft as the rope collecting direction.

For a more detailed construction of the rope collecting mechanism, reference is made to the patent application CN 101963125 A.

As shown in Fig. 2, because the floating body hangs the guide wheel set 27, the direction in which the rope 2 enters the reel 3 is restricted, thereby avoiding the occurrence of the rope 2 obliquely pulling the reel 3 at a large angle, which increases the stability and reliability of the work. And the design of the guide wheel set at a certain distance below the floating body makes the floating body 1 have the ability to automatically correct when tilted. When the floating body 1 is tilted, the rope 2 is bent, and the rope 2 exerts a pressure on the guide wheel set 27, which pressure is generated by the bracket 26 to generate a correcting torque, so that the floating body shell 1 can be corrected, which is important. Because in the rolling waves, because the stability of the floating shell 1 is related to the reliability of power generation.

As shown in Fig. 1, it is also possible to add a diagonal tie rod 26, one end of which is connected to the bottom keel 82 of the floating body, and the other end is connected to the bottom end of the bracket 25 of the guide wheel set 27.

Thus, the force of the waves acts on the floating body casing 1, and then the transfer is concentrated on the keel 82, and the keel 82 exerts a pulling force on the diagonal tie rod 26, and the plurality of diagonally-drawn rods 26 concentrate the pulling force on the guide wheel set 27 (see 6), the rope 2 exerts a downward pulling force on the main shaft 4, and the main shaft passes the groove wall 44 and the bracket 25 to press the guide wheel set 27 downward, thus achieving a balance of forces. The diagonal tie rods 26 are preferably symmetrically distributed, which is advantageous for balancing the force distribution of the keel on the bottom surface of the floating body. Because the area of the floating body tends to be large in actual operation, and the impact force of the wave is large, and the center of the floating body shell 1 is pulled down by the rope 2 in the work, if there is no diagonal rod 26, the keel 82 must have a large The bending moment, the edge of the floating body 1 is upturned. The triangular structure is formed by the diagonal rod 26, the keel 82, and the bracket 27, so that the keel 82 only needs to bear the horizontal pressure, and the diagonal rod can bear the tensile force, which greatly enhances the impact resistance of the floating body 1. When the floating body 1 is tilted (see Fig. 2), the rope 2 is bent at a bend, and a pressure is applied to the guide wheel set 27, which causes the left diagonal pull rod 26 to increase the tensile force, and the right diagonal pull rod 26 receives the tensile force decrease. , the bracket 25 is only under pressure and will not be bent by the overturning moment.

In addition, the rope can also be a chain 30 (see Fig. 5), the drum is a sprocket 77, and a guide sprocket 79 is pressed at a place where the chain 30 enters and exits the sprocket 77, and the chain barrel 78 is suspended from the floating body, and the chain 30 is terminated. On the anchor 57 or fixed platform, the other end passes through the guide The wheel set, the guide sprocket 79, the sprocket 77, and the guide sprocket 79 are stacked in the chain barrel 78; because the chain is stronger and wearable than the rope, the wave collecting ability, durability and reliability are greatly enhanced.

It can be seen from Fig. 1 that the collecting device has only one guiding wheel set located below the center of the floating body, and the diagonal pulling rods are symmetrically distributed at the center point, so that the floating body can be balanced by force, if one guiding wheel set is placed at each end of the floating body, It will cause the center of the floating body to be bent and easily broken.

As shown in FIG. 4, the floating body shell 1 has a groove 44 or two convex hulls 85. The two ends of the main shaft pass through the groove wall 44 or the two protrusions 85 into the floating body cavity, and the groove 44 or the convex hull 85 may be a part in which the floating body shell is separated, but a sealing pad 83 or a sealing glue is attached to the surface of the groove or the convex end of the convex body and the floating body; the groove 44 or the convex bag 85 and the floating body 1 are separate parts, Conducive to production and assembly.

Referring to FIG. 1 and FIG. 6, a vertical tube 73 may be closely attached below the floating body shell groove or convex hull, and the vertical tube accommodates the groove 44 or the convex hull 85 in the vertical direction, and has a gasket 83 at the fitting place or The sealant is filled, and the groove 44 or the convex hull 85, the floating body casing 1, and the standpipe 73 are fixed together by bolts. This has the advantage that part of the air can be sealed in the riser 73, thereby minimizing the intrusion of seawater into the seal 43.

Referring to Fig. 6, the groove wall 44 or the convex wall 85 is connected to the upper end of the bracket 25 of the guide wheel set 27. The main shaft 4 is provided with a groove wall 44 or a convex wall 85 as a support, and a bearing 84 is inserted inside the seal ring 43 at the insertion hole. . The bracket 25 of the guide wheel set 27 is directly connected to the recess 44 or the convex wall 85, so that the force transmission path is minimized, thereby enhancing reliability.

Referring to Fig. 3, the tension rod 26 has a retractor 76; the production process is easy to adjust, and it is easy to adjust in use after assembly. The guide wheel set 27 is two pairs of fixed pulleys placed axially perpendicular to each other, and the lower pair of fixed pulleys 81 have a larger length; the advantages of the two pairs of fixed pulley sets than the use of only one pair of fixed pulley sets are: The rope 2 does not generate the pulley block The axial pressure, while the length of the lower part is long, in order to make the rope 2 deflect in the axial direction along the lower pulley block, the rope 2 does not touch the lower pulley block, and does not generate axial pressure on the lower pulley block. The bend is at the upper pulley block, and the task of resisting the bias is transferred to the upper pulley block.

Referring to Fig. 6, the reel 3 is axially slidable on the main shaft 4, and both sides of the reel have telescopic bellows 42, connecting the end faces of the shaft 4 and the reel 3; the rope 2 wound on the reel 3 is clamped to the pressing roller Between 38 and the rope groove of the reel 3, the support of the pressure roller 38 can slide on two guide rails 37 or a single non-circular cross-section rail.

The reel 3 can slide axially on the main shaft 4, so that the reel 3 can automatically adjust the deflection angle of the rope 2 to avoid too much axial deflection, and the pressure roller 38 can prevent the rope 2 from being removed from the rope groove of the reel 3. Get rid of.

Referring to Fig. 8, the part of the rope from the anchor base 57 to the water surface that is never wound is replaced by a chain 30. The bottom end of the chain 30 is connected to the anchor base 57, the upper end is bound to the submerged float 32, and the upper end of the chain 30 has a loop 36. , the hook of the lower end of the rope 2 of the wave collecting unit is engaged; the chain 30 can also be replaced by the long rod 33 (Fig. 7).

The underwater rope portion is chained 30 and pulled up by the submersible float, which increases the rigidity of the rope 30 and reduces creep. The hook 36 hook 35 design allows the floating body 1 to be removed from the anchor and is easy to maintain.

Referring to Fig. 9, a plurality of collecting devices are operated in series, and the floating body 1 and the floating body 1 are connected through a hanging ring 36 or a cross cardan shaft 74, a hole is formed in the middle of the cross, and a pipeline 72 such as a hydraulic pipe or a wire or a communication cable passes through the middle. . The cross-over connection between the floats allows the pipeline to be protected from exposure to the outside of the float and is damaged in the event of a collision.

See also Figure 7, which is a way of hanging the power cabin under the floating body. In this case, it is equivalent to hanging the above device under a large floating body. Here, the rope 2 is a thread 34 for collecting the power of the wave. Because of the way of hanging down, the upper and lower floating bodies are connected by ropes, and the function of automatically adjusting the direction of the force is provided, so that the guide wheel set 27 can be omitted.

The process of converting wave power into rotational power according to the present invention is as follows (see Figs. 1, Fig. 6): When the wave rises, under the action of buoyancy and wave pushing force, the floating body 1 also rises, and then the floating body 1 and The distance between the anchors 57 is increased, so that the rope 2 pulls the reel 3 to rotate, and the reel 3 drives the downstream transmission system and the generator through the overrunning clutch 85. The power of the waves is transformed into rotational power. In this process, the rope collecting device is also driven by the main shaft 4 to accumulate energy (such as tightening the spring or raising the weight and compressing the gas spring);

When the wave falls, the floating body 1 follows the wave surface under the action of gravity, and the distance between the floating body 1 and the anchor base 57 is shortened. The wave no longer pushes the floating body 1 up and disappears. Since the overrunning clutch 85 and the retracting pawl mechanism 86 (see Fig. 6) are provided between the reel 3 and the downstream transmission system, the function of the one-way detent mechanism 86 is to prevent the downstream transmission system from acting on the reaction torque. Inverted by the action, the function of the overrunning clutch 85 is such that the reel can be disengaged from the downstream transmission system when it is reversed, otherwise it cannot be reversed because of the action of the retracting detent mechanism 86. Therefore, during the falling of the floating body 1, the reel only reverses the rope collection under the action of the rope collecting device worm spring 86.

It is also possible to adopt a hydraulic method (see Fig. 4), that is, the reel 3 is connected to the plunger pump 89 through the overrunning clutch, and the check valve 90 of the plunger pump 89 is added with a check check valve 90, so that the pumped high pressure hydraulic oil is It is impossible to reverse drive the plunger pump 89 to reverse, and the plunger pump 89 cannot reverse itself because it is impossible to draw the output into a vacuum. With the one-way non-transmission function of the overrunning clutch 87, the reel 3 and the plunger pump 89 are now separated. Thus, when the wave drops the float, the rope 2 becomes slack, and under the reverse torque of the rope collecting device worm 86, the drum reverses to retract the rope 2, and for the chain, the sprocket 77 is The reverse torque of the worm spring 86 is reversed, and the chain is retracted into the chain barrel 78 (Fig. 9).

Then the wave rises again, the rope 2 pulls the reel 3 again, then falls, then retracts, and so on.
