Description

Technical Field

[0001] This utility model relates to the field of new energy power generation technology, specifically to a tidal wave power generation device. Background Technology

[0002] In bays or tidal estuaries, the sea or river water rises and falls twice a day; the morning tide is called high, and the evening tide is called low. As a natural phenomenon, tides facilitate human navigation, fishing, and salt production. This phenomenon is mainly caused by the tidal forces of the moon and sun, as well as the Earth's rotation. During high tide, a large amount of seawater surges in with great kinetic energy; simultaneously, the water level gradually rises, converting kinetic energy into potential energy. During low tide, the seawater rushes back, the water level gradually drops, and potential energy is converted back into kinetic energy. The kinetic and potential energy possessed by seawater during its movement is collectively called tidal energy.

[0003] Tidal power generation devices and wave power generation devices are mostly designed independently, occupying separate spaces and difficult to coordinate. For example, CN 111878297 B discloses a reciprocating tidal power generation device, including a device body, anchor bolts, drive structure, buoy, traction rope, meshing balls, transmission wheel, first shaft, second shaft, winding wheel, rotating structure, and generator body. When the sea level rises with the tide, the buoy at the top of the traction rope pulls the rope using the buoyancy of the seawater. Several meshing balls, evenly spaced along the traction rope, mesh with the transmission wheel inside the device body. As the traction rope is pulled by the buoy, it drives the transmission wheel to rotate. The transmission wheel is connected to the generator body via the first shaft, and the rotation of the transmission wheel generates electricity. The other end of the traction rope is fixedly connected to the winding wheel. As the tide recedes, in conjunction with the rotating structure connected to the other end of the second shaft, the energy of the receding tide's flow is used to wind up the traction rope, simultaneously converting the energy of the receding tide's flow into electrical energy.

[0004] Another announcement, CN206419157U, discloses a floating wind and wave integrated power generation device, including a fairing device for absorbing waves and converting them into electrical energy; an anchor connected to the fairing device via an anchor chain to fix the entire device; a support platform connected above the fairing device to provide support for the wind power generation device, and an energy control cabinet installed inside the support platform to store electrical energy; a wind power generation device fixed on the support platform to absorb wind energy and convert it into electrical energy. This power generation device uses a float to provide buoyancy for the integrated power generation device, while the tail rudder of the wind turbine and fairing enables the device to adapt to the correct wind and current direction to obtain maximum energy.

[0005] Besides the fact that the tidal power generation device and the wind and wave power generation device are designed independently, existing tidal power generation devices suffer from an imbalance in the driving torque on both sides, causing the generator shaft to rotate unstablely, resulting in steering conflicts or speed fluctuations. In view of this, this utility model proposes a tidal wind and wave power generation device. Utility Model Content

[0006] This invention proposes a tidal wave power generation device, which solves the problem of independent design of tidal power generation and wave power generation and the balance of driving torque on both sides in the prior art.

[0007] The technical solution of this utility model is as follows: A tidal wave power generation device includes a pipe pile vertically inserted into the seabed. The pipe pile is close to the shore. A water inlet is opened on the side of the bottom of the pipe pile facing away from the shore. A top cover is fixed to the top of the pipe pile. A frame is fixed on the top cover. A floating mechanism that rises and falls with the change of sea level with the tide and a first power device that generates electricity by rising and falling with the floating mechanism are arranged on the frame. A movable component that swings back and forth under the action of wind and waves is arranged on the side of the pipe pile facing the shore. A second power device that generates electricity by swinging the movable component is arranged above the water inlet of the pipe pile.

[0008] Preferably, the floating mechanism includes a floating disc, which is slidably disposed inside the pipe pile. A double-sided toothed rod is fixed to the top of the floating disc by a support, and the double-sided toothed rod is vertically slidably connected to the frame.

[0009] Preferably, the first power unit includes a first device box and a first generator fixed inside the first device box. The first device box is fixed to a frame. A first gear is fixed on the motor shaft of the first generator. A first transmission shaft is provided on one side of the first gear, and a second transmission shaft is provided on the other side of the first gear. The first transmission shaft and the second transmission shaft are rotatably connected to the frame through bearings. The first transmission shaft and the second transmission shaft are axially parallel to the motor shaft of the first generator. A second gear that meshes with a double-sided rack is fixed on both the first transmission shaft and the second transmission shaft. A third gear is fixed on the first transmission shaft. The third gear drives in the same direction as the first gear through a synchronizing element. A fourth gear is fixed on the second transmission shaft. The fourth gear drives in the opposite direction to the first gear.

[0010] Preferably, the first gear includes an internal gear disk, and external gear disks are symmetrically arranged at both ends of the internal gear disk.

[0011] Preferably, the third gear is connected to the internal gear disc via a synchronous belt.

[0012] Preferably, the fourth gear meshes with both external gear discs simultaneously.

[0013] Preferably, the transmission ratio between the third gear and the internal gear disk is the same as the transmission ratio between the fourth gear and the external gear disk.

[0014] Preferably, the movable component includes an arc-shaped plate adapted to the curvature of the pipe pile, with wing plates fixed on both sides of the arc-shaped plate, and a first hinge seat hinged to the lower end of the arc-shaped plate, the first hinge seat being fixed to the outside of the pipe pile.

[0015] Preferably, the second power unit includes a second device box and a second generator fixed inside the second device box. The second device box is fixed outside the pipe pile. The motor shaft of the second generator is a central through-type shaft with pulleys fixed at both ends. A fixing frame is rotatably connected to the outside of the pulleys, and the fixing frame is fixed outside the pipe pile.

[0016] Preferably, the second power device further includes a traction rope, one end of which is connected to the wing plate, and the other end of which passes over the pulley and is connected to a spring support rod. The end of the spring support rod away from the traction rope is hinged to a second hinge seat, which is fixed to the lower end of the arc-shaped plate.

[0017] The working principle and beneficial effects of this utility model are as follows: 1. The bottom of the pipe pile has a water inlet on the side facing away from the coast. The internal floating plate rises and falls with the tides, and the floating mechanism drives the first power unit to generate electricity. The pipe pile has a movable component on the side facing the coast, which swings back and forth under the action of wind and waves. The second power unit converts the kinetic energy of the swing into electrical energy. Both share the same pipe pile. The top cover and frame provide support for the tidal energy system, and the outside of the pipe pile provides the installation foundation for the wind and wave energy system. This compact design integrates the two energy utilization systems into the same pipe pile structure, realizes the synchronous recovery of tidal energy and wind and wave energy, and improves the energy utilization efficiency per unit space.

[0018] 2. The floating roof is connected to a double-sided toothed rod via a support. The toothed rod slides vertically with the floating roof and simultaneously meshes with the second gears on both sides. When the floating roof rises, it drives the first drive shaft to rotate, which drives the inner toothed disc via a synchronous belt, causing the motor shaft to rotate in the forward direction. The second drive shaft rotates in the reverse direction, driving the outer toothed disc via the fourth gear, causing the motor shaft to rotate in the forward direction. The transmission ratio between the third gear and the inner toothed disc is equal to the transmission ratio between the fourth gear and the outer toothed disc, ensuring that the driving torque on both sides is balanced when the floating roof rises / falls, and that the generator motor shaft rotates stably, avoiding steering conflicts or speed fluctuations.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 and Figure 2This utility model discloses a tidal wave power generation device, including a vertically inserted pipe pile 1 on the seabed. The pipe pile 1 is close to the shore, and a water inlet 11 is opened on the side of the bottom of the pipe pile 1 facing away from the shore. A top cover 2 is fixed to the top of the pipe pile 1, and a frame 3 is fixed on the top cover 2. A floating mechanism 4 that rises and falls with the tide level is provided on the frame 3, and a first power device 5 that generates electricity by rising and falling with the floating mechanism 4 is provided. A movable component 6 that swings back and forth under the action of wind and waves is provided on the side of the pipe pile 1 facing the shore. A movable component 6 is provided above the water inlet 11 of the pipe pile 1. The second power unit 7 generates electricity by swinging the movable component 6, and drives the first power unit 5 to generate electricity through the floating mechanism 4. The movable component 6 is located on the side of the pipe pile 1 facing the coast. It swings back and forth under the action of wind and waves. The second power unit 7 converts the swing kinetic energy into electrical energy. The two share the same pipe pile 1. The top cover 2 and the frame 3 provide support for the tidal energy system. The outside of the pipe pile 1 provides the installation foundation for the wind and wave energy system. The compact design integrates the two energy utilization systems into the same pipe pile 1 structure, realizes the synchronous recovery of tidal energy and wind and wave energy, and improves the energy utilization efficiency per unit space.

[0024] Please see Figure 3 The floating mechanism 4 includes a floating plate 41, which is slidably disposed inside the pipe pile 1. A double-sided toothed rod 43 is fixed to the top of the floating plate 41 by a support 42. The double-sided toothed rod 43 is vertically slidably connected to the frame 3. When the tide rises, seawater enters the pipe pile 1 and pushes the floating plate 41 to rise. When the tide falls, seawater is discharged from the floating plate 41 and it descends.

[0025] Please see Figure 3 and Figure 4 The first power unit 5 includes a first device box 51 and a first generator 52 fixed inside the first device box 51. The first device box 51 is fixed to the frame 3. A first gear 53 is fixed on the motor shaft of the first generator 52. A first transmission shaft 54 ​​is provided on one side of the first gear 53, and a second transmission shaft 55 is provided on the other side of the first gear 53. The first transmission shaft 54 ​​and the second transmission shaft 55 are rotatably connected to the frame 3 through bearings. The first transmission shaft 54 ​​and the second transmission shaft 55 are axially parallel to the motor shaft of the first generator 52. A second gear 56 that meshes with a double-sided rack 43 is fixed on both the first transmission shaft 54 ​​and the second transmission shaft 55. A third gear 57 is fixed on the first transmission shaft 54. The third gear 57 drives in the same direction as the first gear 53 through a synchronizing element. A fourth gear 58 is fixed on the second transmission shaft 55. The fourth gear 58 drives in the opposite direction to the first gear 53.

[0026] Please see Figure 4 and Figure 5The first gear 53 includes an internal gear disk 531, with external gear disks 532 symmetrically arranged at both ends of the internal gear disk 531. The third gear 57 is connected to the internal gear disk 531 via a synchronous belt 59. The fourth gear 58 meshes with both external gear disks 532 simultaneously. When the floating disk 41 rises, it drives the first transmission shaft 54 ​​to rotate, which drives the internal gear disk 543 via the synchronous belt 59, causing the motor shaft to rotate in the forward direction. The second transmission shaft 55 rotates in the reverse direction, which drives the external gear disks 532 via the fourth gear 58, causing the motor shaft to rotate in the forward direction. The transmission ratio between the third gear 57 and the internal gear disk 531 is equal to the transmission ratio between the fourth gear 58 and the external gear disk 532, ensuring that the driving torque on both sides is balanced when the floating disk 41 rises / falls, and that the generator motor shaft rotates stably, avoiding steering conflicts or speed fluctuations.

[0027] Please see Figure 1 and Figure 6 The active component 6 includes an arc-shaped plate 61, which is adapted to the curvature of the pipe pile 1. Wing plates 62 are fixed on both sides of the arc-shaped plate 61. A first hinge seat 63 is hinged to the lower end of the arc-shaped plate 61. The first hinge seat 63 is fixed to the outside of the pipe pile 1. The wing plates 62 on both sides increase the wind / wave area. The lower end is hinged to the pipe pile 1 through the first hinge seat 63 and can swing back and forth around the first hinge seat 63.

[0028] Furthermore, the second power unit 7 includes a second device box 71 and a second generator fixed inside the second device box 71. The second device box 71 is fixed outside the pipe pile 1. The motor shaft of the second generator is a central through-type shaft with pulleys 72 fixed at both ends. A fixing frame 76 is rotatably connected to the outside of the pulleys 72. The fixing frame 76 is fixed outside the pipe pile 1. The outside of the pulleys 72 is limited by the fixing frame 76 to ensure rotational stability.

[0029] Furthermore, the second power unit 7 also includes a traction rope 73. One end of the traction rope 73 is connected to the wing plate 62, and the other end of the traction rope 73 passes around the pulley 72 and is connected to a spring support rod 74. The end of the spring support rod 74 away from the traction rope 73 is hinged to a second hinge seat 75, which is fixed to the lower end of the arc plate 61. One end of the traction rope 73 is connected to the wing plate 62, and the other end passes around the pulley 72 and is connected to the spring support rod 74. The other end of the spring support rod 74 is connected to the lower end of the arc plate 61 through the hinged second hinge seat 75, forming an elastic closed loop. When the wind and waves push the arc plate 61 to swing, the traction rope 73 pulls the pulley 72 to rotate (driving the generator), while simultaneously stretching / compressing the spring support rod 74. When the wind and waves weaken, the elastic force of the spring support rod 74 drives the arc plate 61 to reset, and pulls the pulley 72 to rotate in the opposite direction again, realizing the full-cycle energy recovery of reciprocating swing.

[0030] The working principle and specific process of this utility model are as follows: In the initial state, the floating plate 41 is sunk to the lowest position inside the pipe pile 1. When the tide rises, the sea level rises, and seawater enters the pipe pile 1 through the inlet 11, causing the floating plate 41 to gradually rise, thereby driving the double-sided toothed rod 43 to rise synchronously. The double-sided toothed rod 43, through meshing with the second gears 56 on both sides, drives the first transmission shaft 54 ​​and the second transmission shaft 55 to rotate synchronously. The third gear 57, through the synchronous belt 59 and the internal gear disk 531, drives the motor shaft of the first generator 52 to rotate, while the fourth gear 58... The meshing with the external gear disk 532 drives the motor shaft of the first generator 52 to rotate in the opposite direction. Since the transmission ratio of the third gear 57 to the internal gear disk 531 is the same as the transmission ratio of the fourth gear 58 to the external gear disk 532, the motor shaft is driven by the force on both sides to maintain the stable operation of the first generator 52. When the tide recedes, the sea level drops and the seawater is discharged from the pipe pile 1 through the inlet 11, causing the floating plate 41 to gradually descend. Through the mutual transmission of each gear set, the motor shaft is driven again. Through the tidal effect of the seawater, the first generator 52 can output AC power. On the side of the pipe pile 1 facing the coast, a movable component 6 is installed. The wind and waves cause the wing plate 62 and the arc plate 61 to swing back and forth outside the pipe pile 1. The traction rope 73 swings back and forth under the elastic pull of the spring support rod 74, and the pulley 72 rotates back and forth. This causes the central through-type shaft to drive the second generator to work. With the back and forth push of the waves, the second generator can output another part of the AC power, thereby realizing the synchronous utilization of tidal energy and wind and wave energy.

[0031] The core innovation of this utility model lies in the synergistic utilization of multiple energy sources and the balanced torque design of the transmission mechanism: by integrating tidal and wind wave energy to improve energy utilization efficiency, by using a special gear set to solve the problem of power generation stability during tidal rise and fall, and by using an elastic reset mechanism to enhance the recovery efficiency of wind wave energy, it has significant improvements in efficiency, stability and compactness compared to existing single energy devices or simple integrated devices.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the technical principles of the present utility model should be included within the protection scope of the present utility model.
