Technical Field

[0001] This utility model relates to the field of photovoltaic engineering cleaning technology, specifically a surface cleaning device for photovoltaic engineering. Background Technology

[0002] Solar cells, connected in series and then encapsulated for protection, can form large-area solar cell modules. Combined with components such as power controllers, this constitutes a photovoltaic (PV) power generation device. Solar power generation usually refers to solar photovoltaic (PV) power generation. PV power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. The key component of this technology is the solar cell. Solar cells, connected in series and then encapsulated for protection, can form large-area solar cell modules. Combined with components such as power controllers, this constitutes a photovoltaic power generation device. Photovoltaic engineering encompasses the research and development of a system engineering project for solar power generation; another meaning of photovoltaic engineering refers to the equipment engineering that utilizes solar power generation.

[0003] During the installation and production testing of photovoltaic projects, the top of photovoltaic solar panels will accumulate debris and dust due to various environmental factors. Since most linearly arranged photovoltaic panels have a certain tilt angle, the cleaning work is labor-intensive for operators. Furthermore, traditional cleaning methods such as wiping or direct water jetting have certain problems of inconvenience and low cleanliness. Based on this, a surface cleaning device for photovoltaic projects is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a surface cleaning device for photovoltaic engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface cleaning device for photovoltaic engineering, comprising a mounting frame, with extension frames fixedly mounted on the outer sides of both ends of the mounting frame, and support bearings sleeved on the inner sides of both ends of the mounting frame. A hollow tube is movably sleeved on the inner side of each support bearing, and a cleaning motor is drivenly connected to one end of the hollow tube. The hollow tube has several water-permeable holes in its wall, and a sealing bearing is sleeved on the inner side of the hollow tube away from the cleaning motor. A sealing ring is provided on one side of the sealing bearing, and a water inlet connector is movably sleeved on the inner side of the sealing bearing. Two connecting seats are fixedly installed on the top of the frame, and a pull frame is movably installed on the top of the two connecting seats. A push-pull rod is fixedly installed at the front end of the pull frame. A support column is fixedly installed on the opposite side of the extension frame. A rolling bearing is movably sleeved on the outside of the support column. A rubber support wheel is sleeved on the outside of the rolling bearing. A connecting bolt is threaded to the outer end of the support column. A cotton cloth sleeve is fixedly sleeved on the outside of the hollow tube. A cleaning roller sleeve is fixedly sleeved on the outside of the cotton cloth sleeve. Support rods are fixedly installed on the top of both the front and back sides of the mounting frame. Two positioning support wheels are movably installed on the end of the support rod away from the support rod.

[0006] Preferably, the end of the cleaning motor away from the hollow tube is fixedly installed on the inner side of the extension frame, and one end of the hollow tube is open and the other end is sealed.

[0007] Preferably, the water-permeable holes are evenly distributed in a circular linear pattern inside the hollow tube, and the cleaning roller sleeve is made of combed cotton flannel.

[0008] Preferably, the sealing ring is movably sleeved on the inner side of the hollow tube, the sealing ring is fixedly sleeved on the outer side of the water inlet connector tube, and the water inlet connector tube is fixedly inserted through the extension frame and extends to the top of the extension frame.

[0009] Preferably, the pull frame is installed through the top of the connecting seat by a bolt, one end of which is threaded into the interior of the extension column.

[0010] Preferably, the support rod is located in the middle of the mounting frame, and the positioning support wheels are symmetrically and evenly distributed on both sides of the support rod and the mounting frame. The bottom of the positioning support wheel and the bottom of the rubber support wheel are on the same plane.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this device, the user connects the water pump output pipe to the outside of the water inlet connector pipe, then holds the push-pull rod and places the installation frame on top of the photovoltaic panel to be cleaned. At this time, the external power supply starts the cleaning motor to rotate, which drives the hollow tube to rotate. The hollow tube remains stable under the support of the support bearing. The rotation of the hollow tube drives the cotton cloth sleeve and the cleaning roller sleeve to rotate. The cleaning roller sleeve contacts the surface of the photovoltaic panel. Water flows into the interior of the hollow tube through the water inlet connector pipe and is wetted by the cotton cloth sleeve under the guidance of the water permeable holes. It is then sprayed onto the inside of the cleaning roller sleeve. Thus, after the cleaning roller sleeve absorbs water, it rotates and wipes the top of the photovoltaic panel for cleaning. With the guidance of the water flow, the cleaned debris and dust are washed away. The operator holds the push-pull rod to push and pull the installation frame on top of the photovoltaic panel, which is convenient for moving and cleaning on top of the photovoltaic panel. The effect of use is good.

[0012] This invention uses positioning support wheels and rubber support wheels to move on top of the photovoltaic panel and maintain the same support plane, which facilitates the movement and stabilization of the wiping position of the cleaning roller sleeve. This reduces the labor intensity of the operators, who only need to push and pull the push-pull rod back and forth, and coordinate with the up and down pushing and pulling action of the upper arm, which reduces the fatigue of the operators, increases convenience, and makes the operation more convenient.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a surface cleaning device for photovoltaic engineering, including a mounting frame 1, with extension frames 2 fixedly installed on the outer sides of both ends of the mounting frame 1, and support bearings 12 sleeved on the inner sides of both ends of the mounting frame 1. A hollow tube 11 is movably sleeved on the inner side of the support bearing 12, and a cleaning motor 10 is connected to one end of the hollow tube 11. Several water-permeable holes 13 are opened in the tube wall of the hollow tube 11. A sealing bearing 16 is sleeved on the inner side of the hollow tube 11 away from the cleaning motor 10, and a sealing ring 20 is provided on one side of the sealing bearing 16. A water inlet connector 7 is movably sleeved on the inner side of the sealing bearing 16. The top of the mounting frame 1... Two connecting seats 14 are fixedly installed on the main body. A pull frame 3 is movably installed on the top of the two connecting seats 14. A push-pull rod 4 is fixedly installed on the front end of the pull frame 3. A support column 17 is fixedly installed on the opposite side of the extension frame 2. A rolling bearing 18 is movably sleeved on the outside of the support column 17. A rubber support wheel 8 is sleeved on the outside of the rolling bearing 18. A connecting bolt 19 is threaded on the outer end of the support column 17. A cotton cloth sleeve 15 is fixedly sleeved on the outside of the hollow tube 11. A cleaning roller sleeve 9 is fixedly sleeved on the outside of the cotton cloth sleeve 15. Support rods 5 are fixedly installed on the top of both the front and back sides of the mounting frame 1. Two positioning support wheels 6 are movably installed on the end of the support rod 5 away from the support rod 5.

[0020] The working principle of the above technical solution is as follows: During use, the user connects the water pump output pipe to the outside of the water inlet connector pipe 7, and then holds the push-pull rod 4 and places the mounting frame 1 on top of the photovoltaic panel to be cleaned. At this time, the external power supply starts the cleaning motor 10 to rotate. The cleaning motor 10 drives the hollow tube 11 to rotate. The hollow tube 11 is kept stable under the support of the support bearing 12. The rotation of the hollow tube 11 drives the cotton cloth sleeve 15 and the cleaning roller sleeve 9 to rotate. The cleaning roller sleeve 9 contacts the surface of the photovoltaic panel. The water flow is introduced into the interior of the hollow tube 11 through the water inlet connector pipe 7, and is soaked by the cotton cloth sleeve 15 under the guidance of the water permeable hole 13, and sprayed to the inside of the cleaning roller sleeve 9. Thus, the cleaning roller sleeve 9 absorbs water and rotates to wipe and clean the top of the photovoltaic panel. With the guidance of the water flow, the cleaned debris and dust are washed away. The operator holds the push-pull rod 4 to push and pull the mounting frame 1 on the top of the photovoltaic panel, which is convenient for moving and cleaning the top of the photovoltaic panel. The effect is good.

[0021] In another implementation scheme, such as Figures 1-4As shown, the end of the cleaning motor 10 away from the hollow tube 11 is fixedly installed on the inner side of the extension frame 2. One end of the hollow tube 11 is open, and the other end is sealed.

[0022] After the cleaning motor 10 is fixed, it provides a rotation support position for the hollow tube 11. The opening and sealing of the hollow tube 11 facilitate the introduction of water flow and guide the flow within a specific range, which helps to limit the water flow and water pressure.

[0023] In another implementation scheme, such as Figures 1-4 As shown, the water-permeable holes 13 are evenly distributed in a circular linear pattern inside the hollow tube 11, and the cleaning roller sleeve 9 is made of combed cotton flannel.

[0024] The uniform distribution of the permeable holes 13 facilitates the even discharge of water flowing into the hollow tube 11, thereby stabilizing the jetting and seepage of water. The flexible combed cotton cloth material of the cleaning roller sleeve 9 will not scratch the top of the photovoltaic panel when it comes into contact with the top of the photovoltaic panel. It also helps to increase the flow of water and the cleanliness of the wipe, indirectly reducing the number of cleaning times and further increasing the convenience of wiping and cleaning.

[0025] In another implementation scheme, such as Figures 1-4 As shown, the sealing ring 20 is movably sleeved on the inner side of the hollow tube 11, and the sealing ring 20 is fixedly sleeved on the outer side of the water inlet connector tube 7. The water inlet connector tube 7 is fixedly inserted through the extension frame 2 and extends to the top of the extension frame 2.

[0026] The sealing ring 20 blocks water on the opposite side of the mounting frame 1 and the water inlet connector pipe 7, increasing the sealing performance. Together with the rotation support of the sealing bearing 16, the water flow is discharged through the water permeable hole 13 inside the mounting frame 1, which facilitates the stable fit of the structure and the introduction of water.

[0027] In another implementation scheme, such as Figures 1-4 As shown, the pull frame 3 is installed on the top of the connecting seat 14 by bolts, and one end of the connecting bolt 19 is threaded to the inside of the extension column 17.

[0028] The pull frame 3 is bolted through itself and threaded into the connecting seat 14, thereby installing the pull frame 3 on the top of the connecting seat 14, which facilitates the stable connection of the structure. With the fixed connection of the push-pull rod 4, when the operator is cleaning the top of the linearly arranged and tilted photovoltaic panels, the arm pushes and pulls back and forth and moves up and down in a tilted motion. This arm movement trajectory will reduce the discomfort of the operator being in one position for a long time and reduce the labor intensity of the operation.

[0029] In another implementation scheme, such as Figures 1-3As shown, the support rod 5 is located in the middle of the mounting frame 1, and the positioning support wheels 6 are symmetrically and evenly distributed on both sides of the support rod 5 and the mounting frame 1. The bottom of the positioning support wheel 6 and the bottom of the rubber support wheel 8 are on the same plane.

[0030] The positioning support wheel 6 and rubber support wheel 8 move on the top of the photovoltaic panel and maintain the same support plane, which facilitates the movement and stabilization of the wiping position of the cleaning roller sleeve 9. This reduces the labor intensity of the operators, who only need to push and pull the push-pull rod 4 back and forth and coordinate with the up and down pushing and pulling action of the upper arm. This reduces the fatigue of the operators, increases convenience, and makes the operation more convenient.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
