Description

Technical Field

[0001] The present invention relates to the field of solar energy technology, and in particular to an assembled solar photovoltaic bracket. Background Art

[0002] Solar energy is a clean and renewable energy source that converts light energy directly into electrical energy through solar photovoltaic panels. During use, solar photovoltaic panels usually need to be fixed with brackets to maintain their own stability and to adapt to various usage scenarios. Brackets can be of two types: fixed and tracking. Fixed brackets have a simple structure and are easy to install; tracking brackets can automatically adjust the angle to improve power generation efficiency. In order to extend the service life of the bracket, the bracket material is usually steel or aluminum alloy, which needs to be corrosion-resistant, wind-resistant and snow-resistant.

[0003] During the operation of existing solar photovoltaic panels, due to the influence of the external environment, especially the accumulation of obstructions such as fallen leaves, dust, and bird droppings, the photovoltaic panels may be partially or completely blocked. This not only reduces the photovoltaic panels' ability to receive light, but may also cause a hot spot effect, further damaging the performance of the photovoltaic panels and ultimately leading to low power generation efficiency. Especially in outdoor camps where it rains frequently, the above-mentioned obstruction will further reduce the power generation efficiency of the photovoltaic panels. In addition, traditional bracket designs lack flexibility and are difficult to respond quickly to emergencies or environmental changes. To address the above problems, this application proposes an assembled solar photovoltaic bracket. Summary of the Invention

Detailed implementation mode

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, an assembled solar photovoltaic bracket is proposed to solve the problem that in the use process of existing solar photovoltaic panels, affected by the external environment, the photovoltaic panels are blocked (such as blocked by fallen leaves), resulting in low power generation efficiency. It includes: a chassis 1, the chassis 1 is provided with rollers, and the angle between the chassis 1 and the ground can be changed; a sliding block 2, slidably connected to the chassis 1; a scraping member 301, fixedly connected to the sliding block 2, the scraping member 301 is in contact with the chassis 1, and the scraping member 301 is used to scrape the photovoltaic panel 101; a counterweight 302, slidably connected to the chassis 1, a connecting rope is fixedly connected between the counterweight 302 and the scraping member 301, and the rollers on the chassis 1 are used to guide the connecting rope; a transmission mechanism, arranged on the chassis 1, for making the scraping member 301 and the chassis 1 move relative to each other.

[0028] In the above solution, the chassis 1 is assembled by section steel, which is used to facilitate the transfer on the premise of ensuring the stability of the present invention during the working process, thereby increasing the applicable range. The upper side surface of the chassis 1 is inclined to increase the amount of light received by the photovoltaic panel 101. The weight of the counterweight 302 is slightly greater than that of the scraping member 301, which facilitates the downward sliding of the scraping member 301 along the chassis 1, so as to scrape the fallen leaves on the photovoltaic panel 101. During use, first assemble the chassis 1, and then install the photovoltaic panel 101 on it. The sunlight shines on the photovoltaic panel 101 to generate electricity. In a rainy environment, since the light intensity is originally lower than normal, and fallen leaves often accompany the rainfall process (the leaves fall due to the impact of rain), the fallen leaves will adhere to the photovoltaic panel 101, reducing the light reception degree of the photovoltaic panel 101. At this time, through the transmission mechanism, the scraping member 301 and the chassis 1 perform relative movement (the scraping member 301 moves downward along the chassis 1), and during the process, the counterweight 302 moves upward along the chassis 1, so as to scrape the fallen leaves on the photovoltaic panel 101 by the scraping member 301, thereby ensuring the light reception degree of the photovoltaic panel 101, and further ensuring that the power generation efficiency of the photovoltaic panel 101 in a rainy environment remains at a relatively high level.

[0029] As Figure 1 , Figure 3 and Figure 4 shown, the transmission mechanism includes: a water storage tank 401, fixedly connected to the chassis 1. An inlet is provided on the upper side of the water storage tank 401, and an intercepting net is fixedly connected to the inlet of the water storage tank 401. The intercepting net is inclined to facilitate the separation of impurities; a water pipe 402, fixedly connected and communicated with the water storage tank 401; a rotating member 403, rotatably connected to the chassis 1. The rotating member 403 is provided with a turbine, and the turbine is located in the water pipe 402. The rotating member 403 is located below the water storage tank 401; a rotating shaft 404, rotatably connected to the chassis 1; a first rope 405, wound between the rotating member 403 and the rotating shaft 404; a second rope 406, arranged between the rotating shaft 404 and the sliding block 2; an opening and closing assembly, arranged on the chassis 1, used to block the water pipe 402.

[0030] In the above solution, the axis of the turbine on the rotating member 403 is spatially perpendicular to the axis of the water flow passing through the water pipe 402, which is used to cause the rotating member 403 to rotate relative to the chassis 1. The degree of interception of impurities (such as fallen leaves) by the interception net can be adaptively changed according to the actual application environment. During use in a rainfall environment, rainwater enters from the water inlet on the water storage tank 401, and the rainwater gradually accumulates in the water storage tank 401. When the opening and closing assembly loses the blockage of the water pipe 402, the accumulated rainwater in the water storage tank 401 is discharged after passing through the water pipe 402. During the process of the rainwater flowing in the water pipe 402, when the rainwater contacts the turbine on the rotating member 403, the turbine starts to drive the rotating member 403 to rotate counterclockwise under the action of the impact force of the rainwater (such as Figure 1 the front view direction), the rotating member 403 starts to wind up the first rope 405, the first rope 405 drives the rotating shaft 404 to rotate counterclockwise, the rotating shaft 404 winds up the second rope 406 again, and the second rope 406 drives the scraping member 301 to start moving downward along the chassis 1 through the sliding block 2, so as to scrape the fallen leaves on the photovoltaic panel 101. After the scraping is completed, the scraping member 301 resets under the action of the gravity of the counterweight 302.

[0031] As Figures 3 - 7 shown, the opening and closing assembly includes: a support shell 501, fixedly connected to the chassis 1, the support shell 501 truncates the water pipe 402, and the water pipe 402 is fixedly connected and communicated with the support shell 501; a baffle 502, slidably connected in the support shell 501, the baffle 502 is provided with through holes and grooves arranged at intervals, the baffle 502 is used to block the water pipe 402, and there is an angle between the baffle 502 and the horizontal plane; a float 503, connected to the baffle 502 by a thin rope, the float 503 is located in the water storage tank 401, a first elastic element 504 is fixedly connected between the baffle 502 and the support shell 501, a spring block 505 is installed in the support shell 501, and the grooves on the baffle 502 are used to limit the spring block 505; a trigger assembly, arranged on the chassis 1, used to change the blocking state of the baffle 502 on the water pipe 402, and the trigger assembly includes: a transmission shell 601, fixedly connected to the chassis 1; a piston plate 602, slidably connected in the transmission shell 601, and the sliding block 2 is used to squeeze the piston plate 602; a first pipe 603, fixedly connected between the transmission shell 601 and the support shell 501, the first pipe 603 is communicated with the transmission shell 6, and both of them are filled with a transmission medium; a sliding member 604, slidably connected in the first pipe 603, both the sliding member 604 and the spring block 505 are provided with inclined surfaces, and the inclined surface on the sliding member 604 is used to squeeze the inclined surface on the spring block 505.

[0032] In the above solution, the diameter of the float 503 is greater than the inner diameter of the water pipe 402, and the thin rope on the float 503 is initially in a loose state. The baffle 502 slopes upward from back to front, so that the upward force exerted by the float 503 on the baffle 502 can cause the baffle 502 to slide relative to the support shell 501. The first elastic element 504 is a spring, which is used to reset the baffle 502. The transmission media in both the first pipe 603 and the transmission shell 601 are hydraulic oil. During the process of rainwater accumulating in the water storage tank 401, the liquid level in the water storage tank 401 gradually rises, and the float 503 gradually moves upward under the action of buoyancy. After the thin rope on the float 503 is straightened during the upward movement of the float 503, the float 503 pulls the baffle 502 upward through the thin rope. At this time, the spring block 505 is located in the groove on the front side of the baffle 502, and the baffle 502 is in a limited state. When the force exerted by the float 503 on the baffle 502 is greater than the resistance of the spring block 505 to the baffle 502 (the spring block 505 retracts upward), the baffle 502 begins to slide obliquely upward along the support shell 501 under the action of the pulling force, the first elastic element 504 is compressed, and the through hole on the baffle 502 gradually communicates with the water pipe 402 (that is, the baffle 502 gradually loses the blockage of the water pipe 402). The rainwater accumulated in the water storage tank 401 begins to flow downward through the water pipe 402, and the rainwater finally impacts the turbine on the rotating member 403, causing the rotating member 403 to rotate relative to the chassis 1.

[0033] During the process of the sliding block 2 moving downward along the chassis 1, after the sliding block 2 moves downward to contact the piston plate 602, the sliding block 2 drives the piston plate 602 to move downward together. The piston plate 602 squeezes the hydraulic oil in the transmission shell 601, and the hydraulic oil in the transmission shell 601 enters the first pipe 603. The hydraulic oil in the first pipe 603 squeezes the sliding member 604, and the sliding member 604 moves to the right (taking the direction shown in the figure as an example) and squeezes the spring block 505. The spring block 505 retracts upward and loses the limit on the baffle 502. Subsequently, the baffle 502 resets under the action of the elastic force of the first elastic element 504 and re-blocks the water pipe 402. At this time, the turbine on the rotating member 403 loses the power source, that is, the scraping member 301 begins to move upward (reset) along the chassis 1 under the action of the gravity of the counterweight 302, thereby reducing the degree of intervention of the staff in the present invention and reducing the work intensity of the staff.

[0034] As Figures 6 - 9As shown, it further includes: a discharge housing 701 fixedly connected to the chassis 1. The discharge housing 701 is provided with a water outlet. The width of the water outlet of the discharge housing 701 on the horizontal plane is greater than its height in the vertical direction. The rotating shaft 404 is fixedly connected to one end of the second rope 406, and the second rope 406 is slidably connected to the sliding block 2; an intermediate housing 702 fixedly connected and communicating between the discharge housing 701 and the water storage tank 401; a cross plate 703 slidably connected to the discharge housing 701. The cross plate 703 blocks the water outlet on the discharge housing 701, and a spring is fixedly connected between the cross plate 703 and the discharge housing 701; a second pipe 704 fixedly connected between the sliding block 2 and the discharge housing 701, and a transmission medium is filled in the second pipe 704; an extrusion member 705 slidably connected to the sliding block 2, the extrusion member 705 is fixedly connected to the other end of the second rope 406, and a second elastic element 706 is fixedly connected between the extrusion member 705 and the sliding block 2; a first extrusion block 707 and a second extrusion block 708, both slidably connected to the second pipe 704; a connecting rod 709 fixedly connected to the cross plate 703. The extrusion member 705, the first extrusion block 707, the second extrusion block 708 and the connecting rod 709 are all provided with inclined surfaces. The inclined surface on the extrusion member 705 is used to limit the inclined surface on the first extrusion block 707, and the inclined surface on the second extrusion block 708 is used to limit the inclined surface on the connecting rod 709.

[0035] In the above solution, the cross-section of the middle shell 702 is rectangular, which is used to accelerate the transfer speed of rainwater in the water storage tank 401 into the discharge shell 701. The spring between the cross plate 703 and the discharge shell 701 is used to reset the cross plate 703. The transmission medium in the second pipe 704 is hydraulic oil. The second elastic element 706 is a tension spring, which is used to apply a pulling force to the sliding block 2. There is a gap between the inclined surface on the extrusion member 705 and the inclined surface on the first extrusion block 707. During the process of the rotating shaft 404 winding the second rope 406, the second rope 406 drives the extrusion member 705 to move together (the extrusion member 705 does not contact the first extrusion block 707 during the process), and at the same time, the second rope 406 drives the sliding block 2 to move together by stretching the second elastic element 706 (the extrusion member 705 and the sliding block 2 remain relatively stationary during the process), that is, the scraping member 301 moves downward along the chassis 1 to scrape the fallen leaves on the photovoltaic panel 101. When the scraping member 301 contacts the stubborn impurities on the photovoltaic panel 101, the rotating shaft 404 continues to wind the second rope 406, but the sliding block 2 stops moving. At this time, the second elastic element 706 is further stretched, and the extrusion member 705 continues to move with the second rope 406, and then the extrusion member 705 contacts and squeezes the first extrusion block 707. The first extrusion block 707 starts to move downward and squeezes the hydraulic oil in the second pipe 704. The hydraulic oil in the second pipe 704 starts to squeeze the second extrusion block 708. The second extrusion block 708 moves backward and squeezes the connecting rod 709. The connecting rod 709 drives the cross plate 703 to move upward. The cross plate 703 gradually loses the blockage of the water outlet on the discharge shell 701, and then the rainwater in the discharge shell 701 is discharged from the water outlet thereon to wash the stubborn impurities on the photovoltaic panel 101, so as to reduce the adhesion strength of the stubborn impurities on the photovoltaic panel 101, and further improve the scraping effect of the scraping member 301 on the stubborn impurities.

[0036] As Figures 6 - 8 shown, it further includes: a third pipe 801, fixedly connected between the first pipe 603 and the sliding block 2. The third pipe 801 is filled with a transmission medium and is communicated with the first pipe 603; a third extrusion block 802, slidably connected to the third pipe 801. The third extrusion block 802 is provided with an inclined surface; a limiting block 803, fixedly connected to the extrusion member 705. The limiting block 803 is provided with an inclined surface, and the inclined surface on the limiting block 803 is used to squeeze the inclined surface on the third extrusion block 802.

[0037] In the above solution, the transmission medium in the third pipe 801 is hydraulic oil. There is a gap between the inclined surface of the third extrusion block 802 and the inclined surface of the limit block 803, and this gap is larger than the gap between the inclined surface of the extrusion member 705 and the inclined surface of the first extrusion block 707, which is used to change the blocking state of the baffle 502 on the water passing pipe 402. When stubborn impurities still cannot allow the scraping member 301 to pass after being washed by rainwater, the second rope 406 continues to pull the extrusion member 705 to move together. The extrusion member 705 drives the limit block 803 to move together. After the limit block 803 contacts the third extrusion block 802, the limit block 803 starts to extrude the third extrusion block 802. The third extrusion block 802 starts to extrude the hydraulic oil in the third pipe 801. The hydraulic oil in the third pipe 801 enters the first pipe 603. The hydraulic oil in the first pipe 603 starts to extrude the sliding member 604. The sliding member 604 slides relative to the first pipe 603. At the same time, the inclined surface on the sliding member 604 extrudes the inclined surface on the spring block 505. The spring block 505 retracts and loses the limit on the groove on the baffle 502. Subsequently, the baffle 502 resets under the action of the spring force. In this way, the baffle 502 blocks the water passing pipe 402. Subsequently, the rotating member 403 loses the power source. Then, the scraping member 301 starts to reset under the pulling action of the counterweight 302. In this way, it is avoided that the interaction force between the scraping member 301 and the stubborn impurities is too large, resulting in damage to the surface of the photovoltaic panel 101 due to the adhesion force, thus affecting its normal operation. As the rainwater in the water storage tank 401 accumulates again, the scraping member 301 cleans the photovoltaic panel 101 again. In this way, the cleanliness of the surface of the photovoltaic panel 101 is ensured, and the normal progress of the power generation work is ensured.

[0038] As Figure 7 and Figure 9 shown, it further includes: a one-way plate 901, installed on the sliding block 2; a limiting member 902 is slidably connected to the second pipe 704. The one-way plate 901 is used to extrude the limiting member 902. There is an included angle between the axis of the sliding region of the limiting member 902 in the second pipe 704 and the moving direction of the one-way plate 901, which is used to enable them to be separated smoothly.

[0039] In the above solution, the one-way plate 901 is a spring plate and can be deformed, which is used to be separated from the limiting member 902 smoothly. The passing direction of the one-way plate 901 is from left to right (taking the direction shown as an example). During the reset process of the scraping member 301, the sliding block 2 resets together. The sliding block 2 drives the one-way plate 901 to move together. After the one-way plate 901 contacts the limiting member 902, the one-way plate 901 drives the limiting member 902 together (as Figure 9 shown). Figure 9As shown, when moving to the right), the limiting member 902 squeezes the hydraulic oil in the second pipe 704. The hydraulic oil in the second pipe 704 starts to squeeze the second extrusion block 708. The second extrusion block 708 moves backward and squeezes the connecting rod 709. The connecting rod 709 drives the cross plate 703 to move upward. The cross plate 703 gradually loses the blockage of the water outlet on the discharge housing 701. Then the rainwater in the discharge housing 701 is discharged from its water outlet, thereby finally flushing the photovoltaic panel 101, preventing traces (such as mud marks, etc.) from appearing on the surface of the photovoltaic panel 101 due to the scraping of the scraping member 301, which affects the normal reception of light by the photovoltaic panel 101 and reduces the power generation efficiency.

[0040] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
