Description

Technical Field

[0001] This utility model relates to the field of photovoltaic operation and maintenance technology, specifically to a photovoltaic power generation operation and maintenance device based on solar energy. Background Technology

[0002] Photovoltaic power generation is a clean and renewable energy technology that utilizes the photovoltaic effect of semiconductor materials to directly convert sunlight into electricity. A photovoltaic power generation system includes photovoltaic panels, a controller, and an inverter. Photovoltaic power generation requires outdoor sunlight. When photovoltaic panels are shaded by bird droppings, leaves, dust, etc., the shaded area cannot generate electricity and instead acts as a "resistor" in the circuit, consuming electrical energy and generating a large amount of heat. Therefore, during routine maintenance, it is necessary to clean foreign objects from the surface of the photovoltaic panels regularly.

[0003] In the process of realizing this utility model, the inventors discovered that: When there is bird droppings on the surface of photovoltaic panels, if it is a floor-mounted photovoltaic panel, maintenance personnel can directly use cleaning supplies to clean it manually. However, if it is a raised photovoltaic panel, maintenance personnel cannot directly reach the area that needs to be cleaned, so a cleaning device is required. Currently, there are cleaning devices for photovoltaic panels, but these devices are designed to clean dust from the entire surface of the photovoltaic panel. Generally, all photovoltaic panels in the array are cleaned periodically, so these devices are large and heavy. However, for cleaning bird droppings in a single point or limited area, it is not necessary to clean the entire photovoltaic panel. Only the bird droppings location and the surrounding area need to be cleaned. Large cleaning devices that are large and heavy are not convenient to use in daily maintenance. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, this utility model provides a photovoltaic power generation operation and maintenance device based on solar energy.

[0005] Therefore, the technical solution of this utility model is as follows: a photovoltaic power generation operation and maintenance device based on solar energy, including a box body, a rag fixed to the bottom of the box body, a slider fixed to the top of the box body, a threaded hole on the slider body, a lead screw threadedly connected to the threaded hole, a bearing seat installed at both ends of the lead screw, a motor installed on the bearing seat at one end of the lead screw, the output end of the motor fixedly connected to the lead screw, connecting rods fixed on the bearing seats at both ends of the lead screw, the ends of the two connecting rods fixed to a threaded sleeve, and a fixing rod threadedly connected to the threaded sleeve.

[0006] Furthermore, a limiting sleeve is fitted onto the bottom of the housing, which is placed over a cloth at the bottom of the housing. Multiple fasteners are installed between the limiting sleeve and the housing. The limiting sleeve is used to secure the cloth, ensuring that the cloth does not come off when wiping the photovoltaic panel surface, thus preventing further wiping. The limiting sleeve is connected to the housing via fasteners, allowing for quick and convenient replacement of the cloth by unfastening the fasteners.

[0007] Furthermore, the bottom of the box is provided with dense drainage holes, and a water inlet pipe is installed at the top of the front of the box. The water inlet pipe is connected to the inside of the box, and a plug is inserted at the opening of the water inlet pipe. During cleaning, the cleaning water or cleaning agent inside the box can seep through the drainage holes onto the wiping cloth, so that the wiping cloth can effectively clean the surface of the photovoltaic panel.

[0008] Furthermore, the fixing rod is composed of multiple sections, with the ends of adjacent fixing rods connected by threads; the multi-section fixing rod can be freely assembled and disassembled according to the required cleaning distance, and the detachable multi-section design of the fixing rod also facilitates carrying.

[0009] Furthermore, the bottom of the housing and the limiting sleeve are both designed in a conical shape. The conical structure facilitates the fixing of the cloth with the limiting sleeve and can fix cloths of different thicknesses, ensuring flexibility in use.

[0010] Furthermore, the slider has a through hole through which a positioning rod passes. The two ends of the positioning rod are welded and fixed to the bearing seat. The bearing seats at both ends of the lead screw have holes, and the two ends of the lead screw are sleeved with the holes. The positioning rod ensures that when the lead screw rotates, the slider can move linearly along the lead screw, rather than rotating around the lead screw.

[0011] Furthermore, a fixed seat is provided directly below the bearing seat, and the bearing seat is fixed to the top of the fixed seat. A shaft is fixed on the bearing seat at the middle position of the inner side of the photovoltaic panel, and a roller is sleeved on the shaft. The roller is located on the top surface of the photovoltaic panel and provides rolling support. The roller contacts the surface of the photovoltaic panel. When holding the fixed rod, the roller shares the force of holding the hand, reducing the operating burden. The roller makes rolling contact with the surface of the photovoltaic panel, which facilitates movement on the surface of the photovoltaic panel.

[0012] Furthermore, a battery pack is inserted into the end of the fixing rod, and the battery pack is electrically connected to the motor through a wire, with a switch connected in series on the wire; the battery pack is used to supply power, and can be set in relative position to the housing to form a lever structure when the fixing rod is operated by hand, thereby reducing the operating burden.

[0013] Beneficial Effects: This utility model provides a lightweight solar photovoltaic power generation operation and maintenance device. By setting up a single box and a cloth fixed to the box, the box can move along the direction of the lead screw. The overall structure is compact, controlling weight and making it easy to carry. During cleaning, the motor drives the lead screw to rotate, which in turn moves the box and the cloth to clean bird droppings from the photovoltaic panels, making it convenient to use. The box can be filled with cleaning water or detergent, which seeps into the cloth through the seepage holes during cleaning, ensuring the cloth carries water or detergent for continuous and effective cleaning of the photovoltaic panels, ensuring cleaning results. The cloth is fixed to the box by a limiting sleeve, making cloth replacement convenient and simple. The limiting sleeve and the bottom of the box have a conical structure, which is beneficial for fixing cloths of different thicknesses. Rollers are provided to roll and contact the surface of the photovoltaic panels, reducing the burden of operation and facilitating movement to the cleaning location, further simplifying use.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings, but this embodiment should not be construed as a limitation of this utility model.

[0022] It should be noted that the photovoltaic power generation operation and maintenance device based on solar energy of this utility model mainly solves the problem that the current equipment for centralized cleaning of photovoltaic arrays is large in size and inconvenient for local use in daily operation and maintenance.

[0023] This utility model is as follows Figures 1 to 6 As shown: A photovoltaic power generation operation and maintenance device based on solar energy includes a box 1, a limiting sleeve 3 on the bottom of the box 1, a rag 2 on the bottom of the box 1 between the limiting sleeve 3 and the box 1, and multiple buckles 4 are bolted to the limiting sleeve 3 and the box 1. The buckles 4 include male buckles and female buckles. The female buckles are installed with the limiting sleeve 3 and the male buckles are installed with the box 1. The bottom of the box 1 has dense drainage holes 7. A water supply pipe 5 is welded and installed at the top of the front of the box 1. The water supply pipe 5 is connected to the inside of the box 1. A pipe plug 6 is plugged at the opening of the water supply pipe 5. A connecting rod 18 is fixed to the side of the housing 1. A threaded sleeve 19 is welded to the end of the connecting rod 18 away from the housing 1. A fixing rod 20 is threadedly connected to the threaded sleeve 19. The fixing rod 20 is composed of multiple sections, and the ends of adjacent fixing rods 20 are threadedly connected. When bird droppings are found on the surface of photovoltaic panel 22 during routine maintenance and inspection, first wet the cloth 2 with water, then cover the bottom of the box 1. Hold the limiting sleeve 3 and put it on the bottom of the box 1, so that the limiting sleeve 3 is pressed against the cloth 2, and the cloth 2 is pressed against the box 1, thus fixing the cloth 2. Then fasten the snap fastener 4 to fix the limiting sleeve 3 on the box 1. At this time, open the pipe plug 6 and pour cleaning water or cleaning agent into the water pipe 5, and then put the pipe plug 6 back. Connect the fixing rod 20 to the threaded sleeve 19. Then, hold the fixing rod 20 and extend the box 1 to the bird droppings on the surface of the photovoltaic panel 22. At the same time, place the rag 2 on the surface of the photovoltaic panel 22 to be cleaned. Hold the fixing rod 20 to move the rag 2 back and forth. The rag 2 will wipe the bird droppings on the surface of the photovoltaic panel 22 back and forth. During wiping, the cleaning water or cleaning agent in the box 1 seeps into the rag 2 through the seepage hole 7 to continuously replenish the rag 2 with water or cleaning agent, ensuring the cleaning effect of the rag 2 on the bird droppings.

[0024] In this embodiment, the bottom of the box 1 and the limiting sleeve 3 are both set in a conical structure; The conical structure facilitates the fixing of the rag 2 by the limiting sleeve 3. If both the box 1 and the limiting sleeve 3 are vertical plane features, the distance between the outer wall of the box 1 and the inner wall of the limiting sleeve 3 is always fixed. However, under the conical shape, the distance between the inner walls of the box 1 and the limiting sleeve 3 depends on the distance between the box 1 and the limiting sleeve 3. The limiting sleeve 3 is located below the box 1, and the farther away from the box 1 it is, the greater the distance between the inner wall of the limiting sleeve 3 and the outer wall of the box 1. When the limiting sleeve 3 is fitted onto the box 1 and continuously moves upward, the distance between the inner wall of the limiting sleeve 3 and the outer wall of the box 1 increases. The spacing between the outer walls gradually decreases until the inner wall of the limiting sleeve 3 completely abuts against the outer wall of the box 1. Different inner wall spacings can accommodate the fixing of cloths 2 of different thicknesses. In this way, when cleaning, a wet cloth 2 can be used first for cleaning, and then a dry cloth 2 can be used to wipe away residual water (the water can be poured out or a set of devices without water can be used to replace the dry cloth). This prevents dust or sand in the environment from being absorbed by the water before the residual water evaporates completely, and eventually accumulating on the surface of the photovoltaic panel 22, causing local shading.

[0025] In this embodiment, a slider 8 is welded and fixed to the top of the housing 1. The slider 8 has a threaded hole 9 and a through hole 10. The through hole 10 is located directly above the threaded hole 9. A lead screw 11 is threaded into the threaded hole 9. A positioning rod 12 passes through the through hole 10. The lead screw 11 and the positioning rod 12 are parallel to each other. The positioning rod 12 and the fixing rod 20 are perpendicular to each other. A bearing seat 13 is welded and fixed to both ends of the positioning rod 12. Holes are opened on the bearing seats 13 at both ends of the lead screw 11. The holes coincide with the axis of the lead screw 11. The two ends of the lead screw 11 are sleeved with the holes. A motor 17 is bolted to the bearing seat 13 at one end of the lead screw 11. The motor 17 is a stepper motor. The output end of the motor 17 is fixedly connected to the lead screw 11. Two connecting rods 18 are provided. The two connecting rods 18 are fixed to the bearing seats 13 at both ends of the lead screw 11. The two connecting rods 18 and the fixing rod 20 are arranged in a Y-shape. When holding the fixed rod 20 and extending the rag 2 to the cleaning position, the motor 17 is turned on. The motor 17 rotates, driving the fixed lead screw 11 to rotate. The rotation of the lead screw 11 drives the threaded slider 8 to rotate. The through hole 10 of the slider 8 is sleeved with the positioning rod 12. The positioning rod 12 prevents the slider 8 from rotating, so that when the lead screw 11 rotates, the slider 8 moves linearly along the lead screw 11. The movement of the slider 8 will drive the box 1 fixed to the slider 8 to move, and then drive the rag 2 fixed to the box 1 to move. The motor 17 reciprocates, driving the rag 2 to clean the cleaning position in a reciprocating cycle. There is no need to manually hold the fixed rod 20 to wipe, which has a labor-saving effect.

[0026] In this embodiment, a fixed seat 14 is provided directly below the bearing seat 13. The bearing seat 13 is welded and fixed to the top of the fixed seat 14. A shaft 15 is welded and fixed to the bearing seat 13 at the middle position of the inner side of the photovoltaic panel 22. A roller 16 is sleeved on the shaft 15. The roller 16 is located on the top surface of the photovoltaic panel 22 for rolling support. The ends of the two connecting rods 18 away from the threaded sleeve 19 are fixed to the fixed seats 14 below the two bearing seats 13 by bolts. When holding the fixed rod 20, place the roller 16 on the top surface of the photovoltaic panel 22. At this time, you can hold the fixed rod 20 and push the roller 16 to roll on the surface of the photovoltaic panel 22. The frictional resistance of the rolling contact is low, so as to facilitate the movement of the entire box 1 on the photovoltaic panel 22.

[0027] In this embodiment, a battery pack 21 is inserted into the end of the fixing rod 20 away from the threaded sleeve 19. The battery pack 21 is electrically connected to the motor 17 through a wire, and a switch is connected in series on the wire. The battery pack 21 is used to power the switch. At the same time, the battery pack 21 is located at the end of the fixed rod 20. When operating by holding the fixed rod 20, the housing 1 and the battery pack 21 are located at the two ends of the fixed rod 20 respectively. The hand position is located between the housing 1 and the battery pack 21. The battery pack 21 is equivalent to a counterweight, which can reduce the operating pressure when holding the fixed rod 20.

[0028] Any aspects not described in detail in this specification are techniques well-known in the art.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
