Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, specifically a frame for cleaning photovoltaic panels. Background Technology

[0002] A photovoltaic panel cleaning frame is a device specifically designed to support and protect photovoltaic panels and to work with cleaning equipment to clean their surfaces. Its main purpose is to improve the power generation efficiency and maintenance convenience of photovoltaic systems, while also reducing the frequency of manual cleaning and safety hazards. It is especially suitable for large power plants or high-altitude installation scenarios.

[0003] Chinese patent CN220368682U discloses a frame for cleaning photovoltaic panels, comprising: a frame body, at least one alignment member installed at the bottom of each end, the alignment member having an alignment groove suitable for the photovoltaic panel to pass through, the opening of the alignment groove at one end of the frame body facing the other end of the frame body, all alignment grooves being located within a first plane, and an elastic protective member provided within the alignment groove, the elastic protective member being adapted to provide elastic support for the photovoltaic panel when the side of the photovoltaic panel moves into the alignment groove, and the frame body having a connecting part adapted to install a cleaning component. The photovoltaic panel cleaning frame provided by this utility model ensures a relatively accurate distance between the photovoltaic panel and the connecting part through the alignment member, guaranteeing a stable cleaning effect of the cleaning component. Simultaneously, the elastic protective member within the alignment groove provides elastic support for the photovoltaic panel, reducing damage to the photovoltaic panel surface caused by the cleaning component.

[0004] The aforementioned frame ensures the stability of the cleaning components. However, the existing frame uses a fixed installation for the components that can clean the photovoltaic panels, which limits the cleaning range of the photovoltaic panels. Furthermore, centralized cleaning of the photovoltaic panels can damage the surface of the photovoltaic panels. In addition, photovoltaic panels are usually installed at an angle, so the compatibility of the frame needs to be addressed. Therefore, a frame for cleaning photovoltaic panels is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a frame for cleaning photovoltaic panels, so as to solve the problems of limited cleaning range and damage to photovoltaic panels caused by existing fixed frame cleaning, as well as the compatibility of the frame with photovoltaic panels.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a frame for cleaning photovoltaic panels, comprising a telescopic tube, on which a spray pipe is fixedly installed, and on which a conveying mechanism is provided; the conveying mechanism comprises four fixed frames and a support base, on which a plurality of conveying shafts are rotatably installed, and on which a track is sleeved and installed, and on which fasteners are fixedly installed on both sides of the track, a connecting rod is fixedly installed on one side of one fixed frame, a drive shaft is rotatably installed on the connecting rod, a support plate is rotatably installed on the drive shaft, a pressure shaft is rotatably installed on the support plate, and a limit seat is fixedly installed in the middle of the support plate, a pull shaft is rotatably installed on the limit seat, and a pressure nut is threaded on the pull shaft, a plurality of assembly shafts are fastened and installed between the two drive shafts, and a bidirectional motor is fixedly installed on the connecting rod.

[0007] Preferably, the spray pipe is fixedly connected to the two tracks by two fasteners, and the spray pipe is perpendicular to the two tracks respectively, with the tracks resting on the support.

The four top seats are respectively fixedly installed on the lower side of the four fixed frames and two support seats. Two limit bolts are fixedly installed side by side on each of the four bases. A rotating plate is fixedly installed on the two limit bolts. Several limit grooves are opened side by side on the rotating plate.

[0011] Preferably, the distance between the two limiting bolts is the same as the distance between the limiting grooves, and the limiting bolts are fixedly connected to the rotating plate through the limiting grooves.

[0012] Preferably, one end of the rotating plate is rotatably mounted on a fixed frame, and the heights of the fixed frames on both sides are not the same.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The frame for cleaning photovoltaic panels connects the drive shafts on both sides by controlling several assembly shafts, and fixes the spray pipes to the tracks on both sides through two fasteners. When in use, ensure that the tracks on both sides are parallel, and then control the bidirectional motor to make the drive shafts rotate back and forth, so that the tracks move back and forth under the action of the drive shafts and the pressure shafts, thereby driving the spray pipes to move back and forth, so as to achieve the effect of reciprocating spray cleaning of photovoltaic panels.

[0017] 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. Example

[0018] Combination Figures 1-4A frame for cleaning photovoltaic panels includes a telescopic pipe 1, a spray pipe 2 fixedly mounted on the telescopic pipe 1, and a conveying mechanism 3 provided on the spray pipe 2. The conveying mechanism 3 includes four fixed frames 301 and support bases 302. A plurality of conveying shafts 303 are rotatably mounted on the four fixed frames 301, and tracks 304 are sleeved on the plurality of conveying shafts 303. Fasteners 305 are fixedly mounted on both sides of the tracks 304. A connecting rod 306 is fixedly mounted on one side of one fixed frame 301 for connecting... A drive shaft 307 is rotatably mounted on the rod 306. A support plate 308 is rotatably mounted on the drive shaft 307. A pressure shaft 309 is rotatably mounted on the support plate 308. A limit seat 310 is fixedly mounted in the middle of the support plate 308. A pull shaft 311 is rotatably mounted on the limit seat 310. A pressure nut 312 is threaded onto the pull shaft 311. Several assembly shafts 313 are fastened between the two drive shafts 307. A bidirectional motor 314 is fixedly mounted on the connecting rod 306.

[0019] The spray pipe 2 is fixedly connected to the two tracks 304 via two fasteners 305, and the spray pipe 2 is perpendicular to the two tracks 304 respectively, ensuring that the spray pipe 2 moves back and forth on the photovoltaic panel when the tracks 304 reciprocate. The tracks 304 are mounted on the support 302, which supports the tracks 304 and prevents them from sagging. The tracks 304 are clamped between the drive shaft 307 and the pressure shaft 309. The pull shaft 311 is mounted on the limit seat 310 via a ball-and-socket fastener. By controlling the pressure nut 312, the distance between the ball on the pull shaft 311 and the support plate 308 changes, thereby changing the distance between the support plate 308 and the limit seat 309. 08 rotates around the pressure shaft 309, thereby supporting the track 304 with the pressure shaft 309, which in turn increases the friction between the track 304 and the pressure shaft 309, ensuring that the track 304 is driven when the drive shaft 307 rotates. The drive shaft 307 is fixedly installed on the output end of the bidirectional motor 314, which is used to support the reciprocating rotation of the drive shaft 307. The assembly shaft 313 is composed of a quadrangular prism and a hollow tube, and the quadrangular prism is adapted to the hollow tube. The number of assembly shafts 313 is increased according to the width of the photovoltaic panel, so that the tracks 304 on both sides are always located on both sides of the photovoltaic panel. In use, the length of the spray pipe 2 can be controlled. Example

[0020] See Figure 5 A support mechanism 4 is provided on the lower side of the four fixed frames 301. The support mechanism 4 includes four bases 401 and four top seats 402. The four top seats 402 are respectively fixedly installed on the lower side of the four fixed frames 301 and the two support seats 302. Two limit bolts 403 are fixedly installed side by side on each of the four bases 401. A rotating plate 404 is fixedly installed on the two limit bolts 403. Several limit grooves 405 are opened side by side on the rotating plate 404.

[0021] The spacing between the two limit bolts 403 is consistent with the spacing between the limit grooves 405, ensuring that the two limit bolts 403 can be embedded in the two limit grooves 405 at the same time. The limit bolts 403 are fixedly connected to the rotating plate 404 through the limit grooves 405. One end of the rotating plate 404 is rotatably mounted on the fixed frame 301, so that the fixed frame 301 is still supported when the height of the rotating plate 404 changes. The heights of the two fixed frames 301 are not consistent.

[0022] In actual operation, by controlling several assembly shafts 313 to connect the two drive shafts 307, and fixing the spray pipe 2 to the two track belts 304 through two fasteners 305, when in use, ensure that the two track belts 304 are parallel, and then control the bidirectional motor 314 to make the drive shaft 307 reciprocate, so that the track belt 304 reciprocates under the action of the drive shaft 307 and the pressure shaft 309, thereby driving the spray pipe 2 to reciprocate, so as to achieve the effect of reciprocating spray cleaning of photovoltaic panels; By controlling the spacing between the two limit bolts 403 to be consistent with the spacing between the limit grooves 405, it is ensured that the two limit bolts 403 can be embedded in the two limit grooves 405 at the same time, and the limit bolts 403 are fixedly connected to the rotating plate 404 through the limit grooves 405. One end of the rotating plate 404 is rotatably mounted on the fixed frame 301, so that the fixed frame 301 is still supported when the height of the rotating plate 404 changes. Then, the position of the two rotating plates 404 on the base 401 is modified according to the tilt requirements of the photovoltaic panel, so as to achieve the matching connection between the spray pipe 2 and the photovoltaic panel.

[0023] 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 the 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.
