Description

Technical Field

[0001] The present invention belongs to the technical field of green energy-saving power generation, and in particular relates to a green energy-saving power generation device. Background Art

[0002] Hospitals are special public buildings with large electricity loads, so the application of energy-saving and consumption-reducing measures has become an inevitable trend. In addition to using solar power generation systems to save energy, the effect of energy saving only through solar power generation is not ideal. Therefore, we can save energy and reduce consumption by using wave power generation. Wave power generation is a renewable energy technology that converts the energy of water waves into electricity. It can effectively utilize the energy of the water surface, reduce dependence on traditional energy, achieve the purpose of energy conservation and emission reduction, and greatly reduce the impact on the environment.

[0003] The oscillating float wave power generation device is one form of wave power generation. It utilizes the contact between the float and the water surface. The float moves up and down with the waves, thereby converting the mechanical energy of the float into a form of electrical energy. However, since a single float cannot completely absorb the wave energy on the wave surface within the width of the float, it causes the loss and waste of wave energy.

[0004] In order to solve the above problems, a high-efficiency combined double-float wave energy power generation device is proposed in the Chinese patent with announcement number CN112576432A. Under the action of the incident wave, the oscillating float oscillates up and down, and the wave energy not absorbed by the oscillating float will continue to propagate backward through the oscillating float. Since the waves cannot pass through the wave baffle, the unused waves will gather in front of the swinging float and form a reflected wave. The reflected wave and the incident wave will form a superposition at the oscillating float, which can further improve the energy absorption efficiency of the oscillating float; the waves gathered in front of the swinging float will also cause the swinging float to swing left and right, and the oscillating float and the swinging float will respectively drive the second hydraulic piston and the first hydraulic piston to move, and the hydraulic pistons will then respectively push the second hydraulic cylinder and the first hydraulic cylinder to do work, converting the wave energy into hydraulic energy; the hydraulic energy enters the hydraulic motor and drives the hydraulic motor to rotate, and the hydraulic motor then drives the generator to rotate, realizing the conversion of wave energy into electrical energy.

[0005] The above patent also has the following disadvantages: the wave baffle intercepts the waves and forms energy waves in different directions between the two floats. The energy waves drive the swing float to swing left and right and front and back, causing the first hydraulic piston to be unable to slide stably and coaxially in the first connecting shaft, which not only reduces the kinetic energy conversion efficiency, but also accelerates the damage to the conversion device structure.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0035] Embodiment 1:

[0036] See also Figure 1-Figure 4The present application provides a green energy-saving power generation device, including a mounting plate 100, the bottom wall of the mounting plate 110 is symmetrically fixedly connected with four supporting legs 120, and also includes an oscillation component 200, the oscillation component 200 is provided with two groups, and the two groups of oscillation components 200 are symmetrically arranged below the mounting plate 100, for initially absorbing wave energy; a swing component 300, the swing component 300 is provided with two groups, and the two groups of swing components 300 are symmetrically arranged below the mounting plate 100, for further absorbing the wave energy not absorbed by the oscillation component 200; a conversion component 400, which is arranged above the mounting plate 100, and is used to convert the wave energy absorbed by the oscillation component 200 and the swing component 300 into mechanical energy.

[0037] Each group of swing components 300 includes a fixed block 310 fixedly mounted on the mounting plate 100, a rotating rod 320 is rotatably mounted on the fixed block 310, a swing float 330 in a cylindrical shape is rotatably mounted on one end of the rotating rod 320 away from the fixed block 310, a plurality of movable chambers 350 are symmetrically opened on the top of the swing float 330 with the rotating rod 320 as the center, a rotating block 360 is rotatably connected to the inside of each movable chamber 350, and a baffle 340 is fixedly mounted on one end of the rotating block 360 away from the movable chamber 350, and a torsion spring 370 for resetting the baffle 340 is sleeved on the outer side of the rotating block 360, the swing component 300 also includes a fixed rod 380 fixedly mounted on the bottom wall of the mounting plate 100, a second hydraulic cylinder 390 is fixedly mounted on one end of the fixed rod 380 away from the mounting plate 100, a second actuating rod 311 is slidably mounted on the second hydraulic cylinder 390, and an end of the second actuating rod 311 away from the second hydraulic cylinder 390 is hinged to the rotating rod 320.

[0038] In this embodiment, each group of oscillation components 200 includes a connecting block 210 fixedly mounted on the bottom wall of the mounting plate 100, a transmission rod 220 is rotatably mounted on the connecting block 210, and an oscillation float 230 is rotatably mounted on the end of the transmission rod 220 away from the connecting block 210. It should be noted that the oscillation float 230 needs to be placed on the water surface to swing, while the float 330 is placed below the water surface, and the initial height of the swinging float 330 is lower than the oscillation float 230, so that the wave can first hit the oscillation float 230, and then interact with the swinging float 330 through the guidance of a plurality of baffles 340.

[0039] In this embodiment, each group of oscillation components 200 also includes a first hydraulic cylinder 240 which is inclined and fixedly installed on the mounting plate 100. A first actuating rod 250 is slidably installed on the first hydraulic cylinder 240. The end of the first actuating rod 250 away from the first hydraulic cylinder 240 is hinged to the transmission rod 220. A pressure supply pipe 260 is installed on the end of the first hydraulic cylinder 240 away from the first actuating rod 250. An oil supply pipe 312 is installed on the end of the second hydraulic cylinder 390 away from the second actuating rod 311. The conversion assembly 400 includes a hydraulic motor 410 fixedly installed on the top wall of the mounting plate 100. Two pressure supply pipes 260 and two oil supply pipes 312 are both connected to the hydraulic motor 410. An output shaft 420 is provided on the hydraulic motor 410, and the hydraulic motor 410 and the generator 430 provided on the top wall of the mounting plate 100 are detachably installed.

[0040] Specifically, first, the staff can place the mounting plate 100 in the artificial lake of the hospital, and place the oscillating float 230 on the water surface, and the swinging float 330 below the water surface. When the waves on the lake surface approach the overall device, the waves first hit the oscillating float 230 and make it swing up and down. The oscillating float 230 swinging up and down will repeatedly push the first actuating rod 250 to squeeze the hydraulic oil in the first hydraulic cylinder 240. The hydraulic oil in the first hydraulic cylinder 240 is pressurized and enters the hydraulic motor 410 through the pressure supply pipe 260. The hydraulic motor 410 with liquid inflow works to generate electricity through the rotation of the output shaft 420, so that the generator 430 generates electricity. The waves that pass over the oscillating float 230 will be blocked by a number of baffles 340 and collide with the waves behind in the opposite direction, thereby causing the waves between the oscillating float 230 and the swinging float 330 to overlap each other, so that the swinging float 330 swings left and right following the waves and drives the second actuating rod 311 to repeatedly The hydraulic oil in the second hydraulic cylinder 390 is squeezed, and the squeezed hydraulic oil enters the hydraulic motor 410 through the oil supply pipe 312. The hydraulic motor 410 with liquid in it works, and the generator 430 obtains more power through the rotation of the output shaft 420, thereby improving the power generation efficiency; the wave that passes over the oscillating float 230 is blocked by a plurality of baffles 340 and collides with the rear wave in the opposite direction, and the impact force generated is dispersed to all sides. When the baffle 340 is subjected to an oblique shock wave, it will drive the rotating block 360 to rotate in the active chamber 350, and the oblique impact force is offset by the torsion spring 370 sleeved on the outer periphery of the rotating block 360, thereby reducing the possibility of the second actuating rod 311 tilting and sliding in the second hydraulic cylinder 390, avoiding the wear and structural damage of the second actuating rod 311 under the force of the second hydraulic cylinder 390, thereby improving the service life of the swing device 300, and also improving the energy conversion efficiency of the wave energy conversion structure.

[0041] Embodiment 2:

[0042] Based on the above examples, please refer to Figure 5 and Figure 6Each set of swing components 300 also includes energy absorption grooves 313 respectively opened on multiple baffles 340, and each of the multiple baffles 340 is provided with a sliding groove 314 which is through-connected with the energy absorption groove 313, and a sliding plate 315 is slidably installed inside the sliding groove 314, and the sliding plate 315 is made of elastic metal plate.

[0043] Specifically, when encountering a situation where the waves are large, the waves pass over the oscillating float 230 and approach the baffle 340, and the energy absorption groove 313 can concentrate and guide the wave energy to the swing float 330, thereby improving the energy transfer efficiency; the wave enters the energy absorption groove 313 and pushes the sliding plate 315 in the sliding groove 314 to slide upward, which can increase the swing amplitude of the swing float 330, thereby increasing the hydraulic oil flow of the second hydraulic cylinder 390 and the rotation speed of the hydraulic motor 410, and improving the power generation efficiency; the sliding sliding plate 315 can rise more in the sliding groove 314 when the waves are large to fully absorb the wave energy; when the waves are small, the rising amplitude of the sliding plate 315 is small, but it can still maintain a certain energy conversion efficiency, which not only improves the adaptability sensitivity of the swing device 300, but also improves the use stability of the wave energy conversion structure; the design of the sliding groove 314 and the sliding plate 315 can disperse the impact force of the wave on the baffle 340 to a larger area, reducing the impact force on a single point, thereby reducing the risk of damage to the baffle 340 and other structural components, and further improving the service life of the conversion structure.

[0044] Embodiment three:

[0045] Based on the above embodiments, the difference is that, see Figure 7 The swing device 300 is also provided with a power chamber 316 and an electromagnet 317. The power chamber 316 is provided in the baffle 340, and the power chamber 316 is located directly below the sliding groove 314. The electromagnet 317 is fixedly connected in the power chamber 316, and the electromagnet 317 is externally connected to a power source and a processing control element; the sliding plate 315 is provided with an inner chamber near the power chamber 316, and a magnet is fixedly connected in the inner chamber. The electromagnet 317 has opposite magnetic properties to the magnet in the sliding plate 315. Specifically, when the wind and waves on the water surface are small, the processing control element controls the power supply to energize the electromagnet 317. After being energized, the electromagnet 317 and the magnet with opposite magnetic properties and the sliding plate 315 repel each other. The sliding plate 315 is forced to slide upward in the sliding groove 314, thereby increasing the contact area between the baffle 340 and the wave, thereby enhancing the ability of the swing device 300 to capture wave energy, and further improving the adaptability and energy conversion efficiency of the swing device 300 in a low-energy environment.
