Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving power generation, and in particular to a power generation ship with a circulating power storage function. Background Art

[0002] At present, the kinetic energy brought by the water flow in the river channel has not been fully utilized, especially at the outlet of the hydropower station, the water flow energy is completely wasted and not utilized. Moreover, hydropower generation must build a hydropower dam to generate electricity, and hydropower generation cannot be carried out anywhere in the river channel.

[0003] In the prior art, power generation ships use the propeller blades of the hull to convert water flow energy into mechanical energy and then drive the generator to generate electricity. However, the propeller blades of the power generation ship are arranged under the hull. When the hull is used in the water, the propeller blades below have no effect. However, when the hull needs to be landed for maintenance and overhaul, the blades below cannot be retracted. The hull needs to be flipped over or lifted by lifting equipment for maintenance and overhaul, which makes the maintenance operation difficult. At the same time, when the power generation ship drives the generator rotor shaft to rotate by the rotation of the blades in the water to generate electricity, the water flow in different directions will cause the propeller blades to rotate in different directions. Therefore, it is necessary to use an expensive and complex bidirectional generator for power generation, which increases the equipment cost and maintenance cost, and is not conducive to large-scale market promotion and use.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example: See Figure 1-Figure 9As shown, the present invention provides a technical solution: a power generation ship with a cyclic power storage function, comprising a hull 1, a transmission assembly 2 is arranged at a position near the rear surface of the top of the hull 1, a rotation direction conversion assembly 3 is arranged below the transmission assembly 2, and a blade assembly 4 is arranged below the rotation direction conversion assembly 3, the transmission assembly 2 comprises a mounting frame 201, a first connecting plate 204 is fixedly connected to a position near the top of the rear surface of the mounting frame 201, an electric push rod 207 is installed at a position near the front side of the bottom of the first connecting plate 204, and the telescopic end of the electric push rod 207 is fixedly connected to a second connecting rod 207. The connecting plate 208, the outer surface of the first connecting plate 204 is rotatably connected to the transmission shaft 205, the outer surface of the second connecting plate 208 is rotatably connected to the transmission sleeve 209, the inner surface wall of the transmission sleeve 209 is slidably connected to the outer surface of the transmission shaft 205, the rear surface of the mounting frame 201 is fixedly connected to the first slide rail 210 near the edges on both sides, the rear surface of the first slide rail 210 is slidably connected to the sliding sleeve 211, the rotation direction conversion component 3 includes a U-shaped frame 301, the outer surfaces of both sides of the U-shaped frame 301 are fixedly connected by brackets and two sliding sleeves 211, and the blade assembly 4 is used to transfer water The flow energy is converted into mechanical energy, including a third connecting plate 401. When the device is used, the hull 1 is moved to a place where the water flow is turbulent, and the hull 1 is fixed on the water surface using an anchor. After the water flow energy impacts the blade assembly 4, the propeller 405 is driven to rotate to generate mechanical energy, and then the mechanical energy is transmitted to the rotor shaft of the generator 202 to drive the generator 202 to generate electricity. It can be applied to any water area such as rivers, lakes, and oceans with turbulent water flow, and has the effect of energy-saving power generation. At the same time, under the action of the transmission assembly 2, the blade assembly 4 located below the hull 1 can maintain good stability when working, and can be moved to a height higher than the bottom of the hull 1 when not working, so as to facilitate the landing maintenance and overhaul of the hull 1 in the later stage. Under the action of the rotation direction conversion assembly 3, the rotational force in any direction provided by the forward or reverse propeller 405 in the blade assembly 4 can be converted into the same direction rotational force, and then the rotor shaft of the generator 202 is driven to generate electricity. Therefore, the generator 202 can use conventional unidirectional power generation equipment, and there is no need to use bidirectional power generation equipment with high price and high maintenance cost, which reduces the equipment cost and maintenance cost, and is conducive to large-scale market promotion and use.

[0023] The mounting frame 201 is fixedly connected to the top of the hull 1 near the rear side, and a generator 202 is installed on the top of the mounting frame 201. The rotor shaft of the generator 202 is fixedly connected to the first bevel gear 203, and the top of the transmission shaft 205 is fixedly connected to the second bevel gear 206. The first bevel gear 203 and the second bevel gear 206 are meshed and connected. A power distribution device 11 is installed near the middle of the top of the hull 1. The power distribution device 11 and the generator 202 are electrically connected through a line. A second slide rail 212 is fixedly connected to the rear surface of the mounting frame 201 near the middle, and the rear surface of the second connecting plate 208 is slidably connected to the second slide rail 212. When in use, when the transmission sleeve 209 rotates, it will drive the transmission shaft 205 slidably connected thereto to rotate, thereby driving the second bevel gear 206 to rotate. When the second bevel gear 206 rotates, it will transmit the rotational force to the rotor shaft of the generator 202 through the first bevel gear 203. When the rotor shaft of the generator 202 rotates, the mechanical energy is converted into electrical energy under the action of electromagnetic induction and the electrical energy is transmitted through the line to the distribution equipment 11 for storage and distribution, thereby achieving the effect of converting water flow energy into electrical energy. The second slide rail 212 serves to limit the second connecting plate 208, so that the electric push rod 207 drives the second connecting plate 208 to rise and fall more stably.

[0024] The top of the U-shaped frame 301 is rotatably connected to the third bevel gear 302, the top of the third bevel gear 302 is fixedly connected to the bottom of the transmission sleeve 209, the front and rear inner walls of the U-shaped frame 301 are rotatably connected to the connecting sleeve 303 through the bearing, the opposite ends of the two connecting sleeves 303 are fixedly connected to the fourth bevel gear 305, the two fourth bevel gears 305 are meshed and connected with the third bevel gear 302, and the fourth bevel gear 305 forms a free rotation state through the connecting sleeve 303 and the U-shaped frame 301. When in use, the third bevel gear 302 installed at the top of the U-shaped frame 301 rotates clockwise, which drives the fourth bevel gear 305 on the rear side to rotate clockwise and drives the front side at the same time The fourth bevel gear 305 rotates counterclockwise, and vice versa, when the third bevel gear 302 rotates counterclockwise, it will drive the fourth bevel gear 305 on the rear side to rotate counterclockwise and the fourth bevel gear 305 on the front side to rotate clockwise, and when any one of the three bevel gears rotates, the other two bevel gears will rotate. At the same time, the rotation directions of the two fourth bevel gears 305 on the front and rear sides are always opposite. The third bevel gear 302 is in a driven rotation state, and the rotational force is provided by one of the fourth bevel gears 305. The two fourth bevel gears 305 are in an active rotation and a driven rotation state, and the rotational force is generated by the blade assembly 4, which is mainly used to drive the third bevel gear 302 to drive the transmission sleeve 209 to rotate.

[0025] The inner surfaces of the two connecting sleeves 303 are rotatably connected with an installation shaft 307 through a bearing, and both ends of the installation shaft 307 are fixedly connected with a connecting wheel 308, and the outer surface of the connecting wheel 308 is provided with a wheel groove 309, and the inner surface of the wheel groove 309 near the center of the connecting wheel 308 is rotatably connected with two pins 310, and the outer surface of the pin 310 is rotatably connected with an arc rod 311, and a spring 313 is fixedly connected between the outer surface of the arc rod 311 and the inner surface wall of the wheel groove 309, and the outer surfaces of the two arc rods 311 are fixedly connected with a baffle 312 at a position away from the pin 310, and the outer surfaces of the two connecting sleeves 303 on the opposite sides are fixedly connected with an annular plate 304, and the outer surfaces of the two annular plates 304 on the opposite sides are fixedly connected with a limit rod 306 near the edge, and the limit rod 311 is fixedly connected with the limit rod 306. 06 and baffle plate 312 cooperate, wherein one end of the two arc rods 311 away from the pin shaft 310 extends clockwise toward the installation shaft 307, and the other two arc rods 311 away from the pin shaft 310 One end extends counterclockwise toward the installation shaft 307, and the outer surface of the arc rod 311 is fixedly connected with a resistance block 314 near the pin shaft 310, and the resistance block 314 is in conflict with the inner wall of the wheel groove 309. The wheel groove 309 is used to install the pin shaft 310 and accommodate the arc rod 311. When in use, when the installation shaft 307 rotates forward, it will drive the connecting wheels 308 at the front and rear ends to rotate at the same time. At this time, the arc rod 311 on the surface of the rear pin shaft 310 will rotate outward under the action of the spring 313, and the baffle plate 311 on the surface of the arc rod 311 will rotate and expand during the rotation. 2 will form a conflict with the limiting rod 306 on the surface of the annular plate 304, so that the rear annular plate 304 follows the rear connecting wheel 308 to rotate forwardly. At this time, the forwardly rotating annular plate 304 will drive the fourth bevel gear 305 on the rear side to rotate forwardly through the connecting sleeve 303. During the rotation of the fourth bevel gear 305, the third bevel gear 302 above will be driven to rotate, and under the action of the third bevel gear 302, the fourth bevel gear 305 on the front side will be driven to rotate reversely. When the fourth bevel gear 305 rotates reversely, it will drive the front annular plate 304 to rotate reversely through the front connecting sleeve 303. At this time, the arc rod 311 inside the front connecting wheel 308 is rotating forward, and the front arc rod 311 and the rear arc rod 311 are moving towards The front side ring plate 304 rotates in the opposite direction, so the limiting rod 306 on the surface of the front rotating ring plate 304 will squeeze the outer inclined surface of the front arc rod 311 and make it close to the inside of the wheel groove 309, while the squeezing spring 313 will shrink. Therefore, when the mounting shaft 307 rotates forward, the front side ring plate 304, the connecting sleeve 303 and the fourth bevel gear 305 will not be actively pushed by the front side arc rod 311 but will follow the third bevel gear 302 to rotate in the opposite direction. When the propeller 405 rotates in the opposite direction under the action of the water flow energy and drives the mounting shaft 307 to rotate in the opposite direction, the arc rod 311 in the connecting wheel 308 on the front side of the mounting shaft 307 will be squeezed and closed to the inside of the wheel groove 309 when its outer surface passes through the limiting rod 306 on the surface of the ring plate 304.However, when the arc rod 311 in the connecting wheel 308 on the front side of the mounting shaft 307 rotates in the reverse direction following the annular plate 304, the spring 313 will prop up the arc rod 311 outward and cause the baffle 312 on the surface of the arc rod 311 to conflict with the limiting rod 306. In this state, when the mounting shaft 307 rotates in the reverse direction, it will drive the annular plate 304, the connecting sleeve 303 and the fourth bevel gear 305 on the front side to rotate in the reverse direction synchronously. The rotational force exerted on the third bevel gear 302 above is provided by the fourth bevel gear 305 rotating in the reverse direction on the front side, while the fourth bevel gear 305 on the rear side will be driven by the third bevel gear 302 and rotate forward. In short, when the propeller 405 transmits the forward rotational force, the fourth bevel gear 305 on the rear side will actively drive the third bevel gear 302 to rotate, and the fourth bevel gear 305 on the front side is in a driven state driven by the third bevel gear 302. , the front fourth bevel gear 305 will actively drive the third bevel gear 302 to rotate while the rear fourth bevel gear 305 is in a driven state, so the propeller 405 is in any state, the front and rear third bevel gears 302 are in an active and a passive rotation state, and the front third bevel gear 302 can only rotate in the reverse direction, and the rear third bevel gear 302 can only rotate in the forward direction, so that the rotation direction of the third bevel gear 302 driven by the two is not affected by the propeller 405. During the rotation of the arc rod 311 with the pin 310, after it expands outward to the position of matching with the limit rod 306, the resistance block 314 on the surface of the arc rod 311 will resist the inner wall of the wheel groove 309, limiting its maximum outward rotation range. When the arc rod 311 is squeezed by the pin 310 and turns to the inside of the wheel groove 309, when the resistance block 314 flips outward, it will not conflict with the pin 310 due to its short length. ,

[0026] The third connecting plate 401 is fixedly connected to a position near the rear side of the bottom of the U-shaped frame 301, and a connecting shaft 404 is rotatably connected and penetrates the position near the bottom of the rear surface of the third connecting plate 401, and a propeller 405 is fixedly connected to the rear end of the connecting shaft 404. When in use, when the propeller 405 rotates due to the action of the water flow, it will also drive the connecting shaft 404 to rotate. The third connecting plate 401 is used to install the connecting shaft 404 under the U-shaped frame 301, so that the propeller 405 can be submerged in water while the rotation direction conversion assembly 3 is located above the water surface.

[0027] A large pulley 403 is fixedly connected to the front end of the connecting shaft 404, and a small pulley 402 is arranged above the large pulley 403. The outer surfaces of the large pulley 403 and the small pulley 402 are connected by a transmission belt. The small pulley 402 is fixedly connected to the outer surface of the mounting shaft 307 near the middle. When the connecting shaft 404 rotates, the large pulley 403 is driven to rotate, and when the large pulley 403 rotates, the small pulley 402 is driven to rotate through the transmission belt. Since the small pulley 402 is installed on the surface of the mounting shaft 307, the mounting shaft 307 will rotate synchronously when the small pulley 402 rotates.

[0028] The diameter of the large pulley 403 is larger than that of the small pulley 402. Since the diameter of the large pulley 403 is larger than that of the small pulley 402, the small pulley 402 will rotate multiple times for every rotation of the large pulley 403, thereby increasing the number of rotations of the rotor shaft of the generator 202 and improving the power generation efficiency.

[0029] The effect and working principle achieved by the device are as follows: when the device is used, the hull 1 is moved to a place where the water flow is turbulent, and the hull 1 is fixed on the water surface using an anchor. After the water flow energy impacts the blade assembly 4, the propeller 405 is driven to rotate to generate mechanical energy, and then the mechanical energy is transmitted to the rotor shaft of the generator 202 to drive the generator 202 to generate electricity. It can be applied to any water area such as rivers, lakes, and oceans with turbulent water flow, and has the effect of energy-saving power generation. At the same time, under the action of the transmission assembly 2, the blade assembly 4 located below the hull 1 can maintain good stability when working, and can be moved to a height higher than the bottom of the hull 1 when not working, so as to facilitate the landing maintenance and overhaul of the hull 1 in the later stage. Under the action of the rotation direction conversion assembly 3, the rotation force of any direction provided by the forward or reverse propeller 405 in the blade assembly 4 can be converted into the same direction rotation force, and then the rotor shaft of the generator 202 is driven to generate electricity. Therefore, the generator 202 can use conventional unidirectional power generation equipment, and there is no need to use bidirectional power generation equipment with high price and high maintenance cost, which reduces the equipment cost and maintenance cost, and is conducive to large-scale market promotion and use; When in use, when the hull 1 travels to a turbulent area in the water and then uses an anchor to fix the hull 1 on the water surface, the water flow energy generated by the turbulent water flow can drive the underwater propeller 405 to rotate, and when the propeller 405 rotates, it drives the large pulley 403 to rotate through the connecting shaft 404, and when the large pulley 403 rotates, it drives the small pulley 402 to rotate through the transmission belt, and when the small pulley 402 rotates, it drives the installation shaft 307 to rotate. During this process, the small pulley 402 and the installation shaft 307 rotate in the same direction as the propeller 405. When the installation shaft 307 rotates forward, it drives the connecting wheels 308 at the front and rear ends to rotate at the same time. At this time, the arc rod 311 on the surface of the rear pin shaft 310 will rotate outward under the action of the spring 313 and unfold, and rotate. During this process, the baffle plate 312 on the surface of the arc rod 311 will conflict with the limiting rod 306 on the surface of the annular plate 304, so that the rear annular plate 304 follows the rear connecting wheel 308 to rotate forwardly. At this time, the forwardly rotating annular plate 304 will drive the fourth bevel gear 305 on the rear side to rotate forwardly through the connecting sleeve 303. During the rotation of the fourth bevel gear 305, the third bevel gear 302 above will be driven to rotate, and under the action of the third bevel gear 302, the fourth bevel gear 305 on the front side will be driven to rotate reversely. When the fourth bevel gear 305 rotates reversely, it will drive the front annular plate 304 to rotate reversely through the front connecting sleeve 303. At this time, the arc rod 311 inside the front connecting wheel 308 is rotating forwardly, and The front arc rod 311 and the rear arc rod 311 face opposite directions, so the limiting rod 306 on the surface of the front rotating annular plate 304 will squeeze the outer inclined surface of the front arc rod 311 and make it close to the inside of the wheel groove 309 while squeezing the spring 313 to contract. Therefore, when the mounting shaft 307 rotates forward, the front annular plate 304, the connecting sleeve 303 and the fourth bevel gear 305 will not be actively pushed by the front arc rod 311 but will follow the third bevel gear 302 to rotate in the reverse direction. When the propeller 405 rotates in the reverse direction under the action of the water flow energy and drives the mounting shaft 307 to rotate in the reverse direction, the arc rod 311 in the connecting wheel 308 on the front side of the mounting shaft 307 rotates in the reverse direction, and its outer surface passes through the limiting rod on the surface of the annular plate 304. When the mounting shaft 307 rotates in the reverse direction, the spring 313 will prop up the arc rod 311 and make the baffle plate 312 on the surface of the arc rod 311 and the limit rod 306 form a conflict. In this state, when the mounting shaft 307 rotates in the reverse direction, the front annular plate 304, the connecting sleeve 303 and the fourth bevel gear 305 will be driven to rotate in the reverse direction synchronously. The rotational force on the third bevel gear 302 at the top is provided by the fourth bevel gear 305 rotating in the reverse direction at the front side, and the fourth bevel gear 305 at the rear side will be driven by the third bevel gear 302 and rotate in the forward direction. In short, when the propeller 405 transmits the forward rotational force,The fourth bevel gear 305 on the rear side will actively drive the third bevel gear 302 to rotate, and the fourth bevel gear 305 on the front side will be in a driven state driven by the third bevel gear 302. When the propeller 405 transmits reverse rotation force, the fourth bevel gear 305 on the front side will actively drive the third bevel gear 302 to rotate while the fourth bevel gear 305 on the rear side will be in a driven state. Therefore, in any state of the propeller 405, the front and rear third bevel gears 302 are both in an active and a passive rotation state, and the third bevel gear 302 on the front side can only rotate in the reverse direction, and the third bevel gear 302 on the rear side can only rotate in the forward direction, so that the rotation direction of the third bevel gear 302 driven by the two together is not affected by the propeller 405. When the third bevel gear 302 rotates, it will drive the transmission sleeve 209 to rotate, and when the transmission sleeve 209 rotates, it will drive the transmission shaft 205 to rotate. When the transmission shaft 205 rotates, it will drive the second bevel gear 206 to rotate. When the second bevel gear 206 rotates, it will transmit the rotational force to the rotor shaft of the generator 202 through the first bevel gear 203. When the rotor shaft of the generator 202 rotates, it converts mechanical energy into electrical energy under the action of electromagnetic induction and transmits the electrical energy through the line to the distribution equipment 11 for storage and distribution, thereby achieving the effect of converting water flow energy into electrical energy, and can be applied to any turbulent water areas such as rivers, lakes, oceans, etc. with turbulent water flow, with the effect of energy-saving power generation, thereby generating economic value, and when the rotation direction of the propeller 405 that converts water flow energy into mechanical energy changes underwater, the transmission sleeve 209 will keep rotating in the same direction under the action of the rotation direction conversion component 3 and transmit mechanical energy to the rotor shaft of the generator 202. This design allows the generator 202 to use only a unidirectional power generation device with a relatively simple structure and low use cost, effectively reducing equipment cost and maintenance cost, which is conducive to large-scale market promotion and use; When the hull 1 needs to be landed for maintenance, the electric push rod 207 is started to retract and drive the second connecting plate 208 to move upward. At this time, the second connecting plate 208 will drive the transmission sleeve 209 to move upward. Since the transmission shaft 205 is slidably inserted into the transmission sleeve 209 through the spline and the spline groove, the transmission sleeve 209 moving upward will not affect the cooperation between the transmission shaft 205 and the transmission sleeve 209. When the transmission sleeve 209 moves upward, it will drive the rotation direction conversion assembly 3 and the blade assembly 4 at the bottom to move upward. During this process, the sliding sleeve 211 connected to the surface of the U-shaped frame 301 through the connecting plate will slide upward on the surface of the first slide rail 210 on the rear surface of the mounting frame 201, thereby ensuring the stability of the U-shaped frame 301 during movement. When the electric push rod 207 is fully retracted, the blade assembly 4 will rise from the bottom of the hull 1 to the top, thereby facilitating the landing of the hull 1 and reducing the difficulty of maintenance and overhaul operations.
