Description

Technical Field

[0001] The invention belongs to the field of solar power generation, in particular to a solar power generation component. Background Art

[0002] The main structure of solar power generation components includes solar panels and mounting brackets. Using the photovoltaic effect, when sunlight shines on the solar panels, the solar panels convert light energy into electrical energy. Solar power generation components are generally used outdoors. Dust will accumulate on the surface of the solar panels, reducing the light transmittance of the components. If dust accumulates for a long time, it will block sunlight in serious cases, making the components unable to generate electricity normally. Therefore, the panels need to be cleaned. The cleaning cycle depends on the dust situation. In areas with severe dust, it may need to be cleaned once a week or even more.

[0003] A patent document with publication number CN116633251A discloses a windproof photovoltaic power generation device with high sand removal efficiency, which includes a solar panel, a support base and a sand removal unit. The sand removal unit includes a sand blowing roller. After the wind fan is started, the sand blowing roller blows away the sand and dust on the solar panel, thereby removing the sand and dust on the solar panel.

[0004] There are still some problems in the practical application of the above technical solution. It adopts the method of blowing air to clean and remove sand. Although the surface of the solar panel is provided with protective glass, the sand and dust particles will rub against the glass when the wind blows, which may cause wear and tear and affect the service life of the components. For some areas with special environments, such as the northwest region and plateau areas, these places not only have a large temperature difference between day and night, but also a lot of sand and dust. Sand removal work is more frequent, which will further aggravate this problem. Therefore, the actual use effect of the above technical solution is poor.

[0005] To this end, the present invention provides a solar power generation component. Summary of the invention

[0012] Preferably, the control mechanism further comprises a plurality of temperature-changing components arranged in the support for driving the ratchet plate to move, and the temperature-changing components are connected to the ratchet plate.

[0013] Preferably, the control mechanism also includes: a plurality of rotating wheels rotatably arranged in the support; driven rods evenly distributed in an annular manner on the circumference of the rotating wheel; a baffle and a pressure plate fixedly connected to the rotating wheel, a gap being left between the baffle and the pressure plate, and a slope being provided at the end of the baffle, so that after the rotating wheel rotates, the control plate is driven to approach the ratchet plate through the pressure plate, and the baffle is blocked from moving back through the baffle; a reset spring arranged in the support for driving the control plate away from the ratchet plate; a paddle plate rotatably arranged on the ratchet plate for pushing the driven rod, and during the movement of the ratchet plate, the cooperation between the paddle plate and the driven rod drives the rotating wheel to rotate unidirectionally intermittently.

[0014] Preferably, the control mechanism further includes: two impact plates slidably arranged in the support, the impact plates are used to push the suction plate to move, and the two impact plates are respectively located at both ends of the slide rail; and an energy storage spring arranged in the support for pushing the impact plates.

[0015] Preferably, the control mechanism also includes: a protruding rod fixedly connected to the impact plate; two pushing plates arranged on the control plate for driving the protruding rod to move, the protruding rod and the control plate are staggered, and after the control plate moves, the impact plate is driven away from the suction plate through the cooperation between the pushing plates and the protruding rod.

[0016] Preferably, a slide groove for guiding the air suction plate is provided inside the slide rail, and both ends of the slide groove are provided with a sinking section.

This component saves the trouble of setting up an additional electrical system, saves electricity, simplifies the structure, and is more suitable for power generation components.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Embodiment 1: Figure 1-9 As shown, a solar power generation assembly according to an embodiment of the present invention includes a solar panel 1 and a bracket 2, and also includes a sand removal mechanism 3; The sand removal mechanism 3 includes: a slide rail 31 fixedly connected to the bracket 2; an air suction plate 32 slidably arranged on the slide rail 31, and the air suction plate 32 passes through the surface of the solar cell panel 1 after moving; a support 33 fixedly connected to the bracket 2; a suction pump assembly 34 and a collection bin 35 arranged in the support 33, and the suction pump assembly 34 is used to provide suction force to the air suction plate 32, and the air suction plate 32 sucks sand on the surface of the solar cell panel 1 into the collection bin 35.

[0024] The bracket 2 is provided with an inverter and other devices matching the solar panel 1, and a window for taking out the collection bin 35 is provided on the support 33. Specifically, the X-axis is the front-to-back direction, the Z-axis is the left-to-right direction, and the Y-axis is the up-and-down direction. When each structure moves, the movement along the positive direction of the X-axis is forward movement, and the reverse direction is backward movement; the slide rails 31 are respectively arranged on the front and rear sides of the solar panel 1, and the air intake plate 32 can slide left and right. The air intake plate 32 is located above the solar panel 1, and a hose is provided on the air intake plate 32. The bottom of the air intake plate 32 is provided with an air intake port, and the support 33 is located on the rear side of the solar panel 1. The front side end of the support 33 is provided with an opening for the air intake plate 32 to move; of course, the support 33 can also be arranged at the front side end of the solar panel 1. The structure of the suction plate 32 , the suction pump assembly 34 and the collection bin 35 can adopt the relevant structure of a vacuum cleaner. The suction pump is used to provide suction force to the suction plate 32 . The suction plate 32 sucks away impurities such as sand on the surface of the solar panel 1 and stores them in the collection bin 35 .

[0025] The solar power generation assembly is set up for use outdoors. Initially, Figure 1 As shown, the air suction plate 32 is located on the outside of the solar panel 1 to avoid hindering the contact between the solar panel 1 and the sunlight. After the component has worked outdoors for a period of time, impurities such as sand and dust are attached to the solar panel 1, and it needs to be cleaned. During cleaning, the suction pump component 34 is started, and the air suction plate 32 is moved. In the process of moving from one end of the solar panel 1 to the other end, the air suction plate 32 sucks away impurities such as sand and dust attached to the surface of the solar panel 1, and the impurities sucked away are stored in the collection bin 35. By setting a suction method to clean the solar panel 1, the sand and dust are directly sucked away, which improves the problem of sand and dust rolling on the surface of the solar panel 1 and causing large friction loss in the sand blowing method, thereby extending the service life of the component.

[0026] like Figure 2-6 As shown, the suction pump assembly 34 includes: a pump body 341 fixedly connected to the support 33; and a piston member 342 slidably disposed in the pump body 341.

[0027] Specifically, the suction pump assembly 34 adopts a mechanical suction pump structure, and the piston 342 generates suction force when it reciprocates in the pump body 341. The mechanical suction pump does not require electric drive, thereby saving the electric energy generated by the solar power generation assembly and is more suitable for power generation assemblies.

[0028] like Figure 2-6 As shown, the end of the piston member 342 is fixedly connected to a frame plate 343, and the suction pump assembly 34 is provided with a plurality of groups, and a plurality of the piston members 342 are distributed side by side.

[0029] Specifically, the piston member 342 can move up and down, and the frame plate 343 is arranged at the top of the piston member 342. By arranging multiple groups of suction pump assemblies 34 and performing suction work at the same time, a stronger suction force can be generated, further improving the suction and sand removal effect.

[0030] like Figure 2-6 As shown, it also includes a control mechanism 4, which includes: a plurality of spring assemblies 41 arranged in the support 33; a cam 411 fixedly connected to the output end of the spring assembly 41, and the cam 411 is inserted into the frame plate 343. After the cam 411 rotates, it drives the piston member 342 to reciprocate in the pump body 341 through the frame plate 343.

[0031] Specifically, a plurality of spring assemblies 41 are arranged in a row along the left-right direction, and an anti-overtightening device is provided on the spring assembly 41. After the tightened spring assembly 41 releases energy, it drives the cam 411 to rotate. During the rotation of the cam 411, the piston 342 is driven to move up and down, thereby continuously generating suction force.

[0032] like Figure 2-8 As shown, the control mechanism 4 also includes: a control plate 42 slidably arranged in the support 33; a ratchet 412 fixedly connected to the input end of the spring assembly 41; a plurality of ratchet plates 43 slidably arranged on the control plate 42, the ratchet plates 43 are meshedly connected with the ratchet 412, and after the ratchet plates 43 move back and forth, they drive the ratchet 412 to rotate unidirectionally to tighten the spring assembly 41.

[0033] Specifically, the control panel 42 is located between the solar panel 1 and the clockwork assembly 41, the ratchet plate 43 is arranged on the back of the control panel 42, the control panel 42 does not contact the ratchet 412, the control panel 42 can move forward and backward, the ratchet plate 43 can move up and down relative to the control panel 42, the ratchet plate 43 and the ratchet 412 form a unidirectional rotation mechanism, and the ratchet 412 drives the ratchet plate 43 to rotate unidirectionally after moving up and down, thereby tightening the clockwork assembly 41 to store energy.

[0034] When the control plate 42 is located at the rear end of its moving range, the ratchet plate 43 is in contact and meshing with the ratchet wheel 412. The ratchet plate 43 is always in contact with the ratchet wheel 412 during the up and down movement, which can drive the ratchet wheel 412 to rotate and prevent the ratchet wheel 412 from rotating, thereby preventing the clockwork assembly 41 from rotating and releasing energy.

[0035] After the control plate 42 is moved forward, the ratchet plate 43 and the ratchet wheel 412 are offset from each other, and the ratchet plate 43 and the ratchet wheel 412 are no longer in contact with each other. The non-return function of the ratchet plate 43 is lost, and the clockwork assembly 41 releases energy and drives the cam 411 to rotate.

[0036] like Figure 2-8As shown, the control mechanism 4 further includes a plurality of temperature-changing components 44 disposed in the support 33 for driving the ratchet plate 43 to move, and the temperature-changing components 44 are connected to the ratchet plate 43 .

[0037] Specifically, the temperature-changing component 44 is located above the ratchet plate 43. The temperature-changing component 44 is a material that automatically deforms and recovers due to temperature changes. The temperature-changing component 44 is preferably, but not limited to, a bimetallic strip. The two ends of the bimetallic strip are fixedly mounted on a certain supporting member inside the support 33. A vertical rod is provided on the inner top wall of the bimetallic strip, and the vertical rod is connected to the ratchet plate 43. The installation method of the temperature-changing component 44 is selected according to the situation. One method is: the two ends of the bimetallic strip are fixedly connected to the top of the control board 42, and the vertical rod is fixedly connected to the ratchet plate 43. The other method is: the two ends of the bimetallic strip are directly fixedly connected to the support 33, and the vertical rod is slidably connected to the ratchet plate 43. Other structures that can satisfy the requirement that the temperature-changing component 44 can drive the ratchet plate 43 to move up and down after being deformed with temperature, and the ratchet plate 43 can move forward and backward at the same time, are suitable for the manufacture of the temperature-changing component 44 and the ratchet plate 43.

[0038] During the operation of the power generation component, the temperature variable element 44 will be deformed by the change of external temperature, and drive the ratchet plate 43 to move up and down, thereby tightening the spring component 41, realizing the function of automatically tightening the spring component 41, eliminating the trouble of manual operation, and using the temperature difference as power to drive the automatic operation of the solar cell panel 1 cleaning work, without the need to set up an additional electric drive system, thus saving electricity. For areas such as the northwest region and plateau areas, these areas are not only dusty, but also have a large temperature difference between day and night. The use effect of the temperature variable element 44 is better, and therefore, it is also more suitable for automated sand removal work.

[0039] In addition, by providing multiple groups of suction pump assemblies 34 and spring assemblies 41, multiple spring assemblies 41 are tightened and then released at the same time, which can generate a stronger driving force, thereby driving the suction pump assembly 34 as a whole to generate a stronger suction force, thereby improving the suction and sand removal effect.

[0040] like Figure 2-8As shown, the control mechanism 4 also includes: a plurality of rotating wheels 45 rotatably arranged in the support 33; a driven rod 451 evenly distributed in an annular manner around the rotating wheel 45; a baffle 452 and a pressure plate 453 fixedly connected to the rotating wheel 45, a gap is left between the baffle 452 and the pressure plate 453, and a slope is provided at the end of the baffle 452. After the rotating wheel 45 rotates, the control plate 42 is driven to approach the ratchet plate 43 through the pressure plate 453, and the baffle 452 is blocked from moving back through the baffle 452; a reset spring 421 arranged in the support 33 for driving the control plate 42 away from the ratchet plate 43; a paddle 431 rotatably arranged on the ratchet plate 43 for pushing the driven rod 451, and during the movement of the ratchet plate 43, the cooperation between the paddle 431 and the driven rod 451 drives the rotating wheel 45 to rotate unidirectionally intermittently.

[0041] Specifically, the rotating wheel 45 is located above the control plate 42, and a return torsion spring is provided on the rotating shaft of the dial plate 431, and the return spring 421 is used to pull the control plate 42 forward; during the forward and backward movement of the control plate 42, the dial plate 431 can always be in contact with the driven rod 451, which can be achieved by designing the length of the dial plate 431 or the driven rod 451; Figure 8 As shown, the baffle 452 is in an arc shape, and the back side of the upper end of the pressing plate 453 is provided with a slope, and the back side of the pressing plate 453 is flush with the back side of the baffle 452 .

[0042] In the initial state, if Figure 7 As shown, the ratchet plate 43 is in contact and meshing with the ratchet wheel 412, and the baffle plate 452 blocks the front of the control plate 42 to prevent the control plate 42 from moving forward, so as to ensure that the ratchet plate 43 is in contact with the ratchet wheel 412, and the reset spring 421 is in a stretched state; in the process of the ratchet plate 43 moving up and down, the dial plate 431 drives the rotating wheel 45 to rotate unidirectionally clockwise, and in the process of the rotating wheel 45 rotating, the arc-shaped baffle plate 452 will block the front of the control plate 42 for a period of time, which provides time for the ratchet plate 43 and the ratchet wheel 412 to cooperate with the clockwork assembly 41, and as the rotating wheel 45 continues to rotate, all the baffle plates 452 are separated from the control plate 42, and the pressure plate 453 has not yet been separated from the control plate 42. The control plate 42 contacts the control plate 42. At this time, the return spring 421 drives the control plate 42 to move forward. After the control plate 42 moves forward, the ratchet plate 43 separates from the ratchet wheel 412, and the spring assembly 41 releases energy, driving the piston member 342 to move back and forth to perform suction work; after the control plate 42 moves forward, the ratchet plate 43 will also drive the rotating wheel 45 to rotate unidirectionally. After the spring assembly 41 releases all energy, as the rotating wheel 45 continues to rotate, the pressure plate 453 contacts the control plate 42 and pushes the control plate 42 to move backward, so that the ratchet plate 43 contacts and meshes with the ratchet wheel 412 again, and the spring assembly 41 continues to be tightened. This cycle can automatically alternate between tightening and releasing the spring assembly 41.

[0043] There may be errors in the movement of multiple temperature-changing components 44, and complete synchronization cannot be guaranteed. By setting the control board 42 to prevent the spring assembly 41 from releasing energy, it will not affect the tightening action of each spring assembly 41. In addition, when the pressure plates 453 on all the rotating wheels 45 are rotated to separate from the control board 42, the control board 42 moves forward, all the ratchet plates 43 are separated from all the ratchet wheels 412 at the same time, and all the spring assemblies 41 release energy at the same time. The driving force generated by the multiple spring assemblies 41 can be better integrated, thereby providing a larger and more stable driving force for the suction work, improving the suction intensity and stability of the suction work, and thereby improving the automatic cleaning effect of the solar cell panel 1.

[0044] Embodiment 2: Figure 2-10 As shown, compared with Example 1, another implementation of the present invention is: the control mechanism 4 also includes: two impact plates 46 slidably arranged in the support 33, the impact plates 46 are used to push the suction plate 32 to move, and the two impact plates 46 are respectively located at both ends of the slide rail 31; an energy storage spring 461 arranged in the support 33 for pushing the impact plates 46.

[0045] Specifically, the two ends of the energy storage spring 461 are connected to the support 33 and the striker 46 respectively. Fig.10 Taking an example for explanation, the air suction plate 32 is parked at the left end of the slide rail 31 and rests on the left impact plate 46; when removing sand and cleaning, the impact plate 46 is moved to the left, so that the energy storage spring 461 is compressed, and then the impact plate 46 is released, the energy storage spring 461 releases energy and pushes the impact plate 46 to move right quickly. Under the action of inertial force, the rightward movement range of the impact plate 46 exceeds the initial position. After the impact plate 46 moves to the right, it hits the air suction plate 32, thereby pushing the air suction plate 32 to move right, so that the air suction plate 32 moves from one end of the slide rail 31 to the other end, thereby performing comprehensive sand removal and cleaning on the solar panel 1. Similarly, the impact plate 46 on the right can push the air suction plate 32 to move left; by providing a movable air suction plate 32, the air suction plate 32 moves along the surface of the solar panel 1, and the sand removal effect is better and more comprehensive.

[0046] like Figure 2-11 As shown, the control mechanism 4 also includes: a protruding rod 462 fixedly connected to the impact plate 46; two pushing plates 47 arranged on the control plate 42 for driving the protruding rod 462 to move, and the protruding rod 462 is staggered with the control plate 42. After the control plate 42 moves, the impact plate 46 is driven away from the suction plate 32 through the cooperation between the pushing plates 47 and the protruding rod 462.

[0047] Specifically, the push plate 47 can be a one-way deflection structure, and a cross bar for supporting the push plate 47 is provided on the top of the control plate 42. The collision plate 46 and the protruding rod 462 only contact the push plate 47 during the movement, and do not contact the control plate 42. Fig.10 The second form of the protruding rod 462 and the push plate 47 is that the protruding rod 462 and the cross bar are staggered up and down, and the cross bar is provided with a step for preventing the push plate 47 from rotating clockwise. The two ends of the energy storage spring 461 are respectively connected to the striker 46 and the support 33, and a return torsion spring is provided on the rotating shaft of the push plate 47.

[0048] by Fig.10 For example, initially, the push plate 47 is located behind the protruding rod 462. After the control plate 42 moves forward, the push plate 47 on the left pushes the strike plate 46 on the left to move leftward. As the control plate 42 continues to move forward, the push plate 47 moves to the front of the strike plate 46 and separates from the strike plate 46. Then the strike plate 46 quickly moves rightward and pushes the suction plate 32 to move rightward. When the control plate 42 moves backward, the push plate 47 does not push the strike plate 46 to move. When the control plate 42 moves forward again, the right push plate 47, i.e., the strike rod, cooperates to drive the suction plate 32 to move leftward. In this cycle, after the control plate 42 moves forward, it can automatically drive the suction plate 32 to move back and forth, eliminating the need for an electric system for driving the suction plate 32 to move, simplifying the structure, and saving electricity.

[0049] It should be noted that Fig.11 This is the third form of the push plate 47, which can also be fixed on the cross bar. The front and rear side walls of the push plate 47 are both provided with slopes. After the control plate 42 moves forward and backward, it can drive the impact rod away from the suction plate 32, thereby driving the suction plate 32 to move back and forth.

[0050] like Fig. 9 As shown, a slide groove 311 for guiding the air suction plate 32 is provided inside the slide rail 31 , and both ends of the slide groove 311 are provided with a sinking section.

[0051] Specifically, the air suction plate 32 automatically falls into the sinking section when it moves to the end of the slide groove 311. The sinking section serves to position the air suction plate 32 to prevent the air suction plate 32 from shaking left and right, thereby ensuring that the collision plate 46 can smoothly hit the air suction plate 32.

[0052] Working principle: The solar power generation assembly is used in areas with large temperature differences between day and night and strong winds and sandstorms. Initially, the air intake plate 32 is located outside the solar panel 1 to avoid hindering the contact between the solar panel 1 and the sunlight, and the ratchet plate 43 is in contact and meshing with the ratchet wheel 412; Affected by the external temperature change, the temperature-changing element 44 will continuously deform and recover its deformation, thereby driving the ratchet plate 43 to move up and down. The ratchet plate 43 is always in contact with the ratchet wheel 412 during the up and down movement, thereby driving the ratchet wheel 412 to rotate in one direction, tightening the clockwork assembly 41 to store energy, and at the same time, the ratchet plate 43 can prevent the ratchet wheel 412 from rotating, thereby preventing the clockwork assembly 41 from rotating to release energy; During the up and down movement of the ratchet plate 43, the dial plate 431 drives the rotating wheel 45 to rotate clockwise in one direction. During the rotation of the rotating wheel 45, the arc-shaped baffle plate 452 blocks the front of the control plate 42 for a period of time, providing time for the ratchet plate 43 and the ratchet wheel 412 to cooperate and drive the clockwork assembly 41. As the rotating wheel 45 continues to rotate, when all the baffles 452 are separated from the control plate 42 and the pressure plate 453 has not yet contacted the control plate 42, the return spring 421 drives the control plate 42 to move forward. After the control plate 42 moves forward, all the ratchet plates 43 are separated from the ratchet wheel 412 at the same time, and the multiple clockwork assemblies 41 release energy at the same time, driving the multiple pistons 342 to reciprocate synchronously in the pump body 341, thereby generating a stronger suction force; After the control plate 42 moves forward, the push plate 47 pushes the strike plate 46 to move and then separates from the strike plate 46, and the energy storage spring 461 releases energy and pushes the strike plate 46 to move quickly, hitting the suction plate 32, pushing the suction plate 32 to move from one end of the slide rail 31 to the other end. During the suction plate 32 moving on the surface of the solar cell panel 1, the dust and other impurities attached to the surface of the solar cell panel 1 are sucked away, and the sucked away impurities are stored in the collection bin 35; After the clockwork assembly 41 releases the energy, as the wheel 45 continues to rotate, the pressure plate 453 contacts the control board 42 and pushes the control board 42 to move backward, so that all the ratchet plates 43 contact and engage with the ratchet wheel 412 again, and the work of tightening the clockwork assembly 41 continues; after repeating the above actions, the solar panel 1 can be continuously cleaned.

[0053] When the component is in use, the solar panel 1 is cleaned by setting a suction method to directly suck away the dust, thereby improving the problem of large friction loss caused by dust rolling on the surface of the solar panel 1 in the sand blowing method, extending the service life of the component, and utilizing the temperature difference in the working environment to drive the cleaning work to run continuously. No manual operation is required, and the degree of automation is high. It is more suitable for use in areas with large temperature differences between day and night and much dust. In addition, the power generation component itself is to generate more electricity. If an electrical drive system is set to drive the suction pump component 34 and the suction plate 32 to move, it will undoubtedly consume the electricity generated by the power generation component, thereby reducing the power generation effect. The component saves the trouble of setting up an additional electrical system, saves electricity, simplifies the structure, and is more suitable for power generation components.
