Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning equipment technology, and in particular to a photovoltaic cell module cleaning device. Background Technology

[0002] Photovoltaic module cleaning devices, especially automated cleaning robots, are crucial for maintaining the power generation efficiency of photovoltaic power plants. As a core component that directly contacts the photovoltaic panels, the cleaning roller brush wears down due to frequent use and requires periodic replacement. Currently, the connection and fixation between the cleaning roller brush and the machine body mostly rely on traditional bolts or screws. This structure has revealed significant shortcomings in actual maintenance operations.

[0003] When roller brushes need to be replaced, maintenance personnel must carry specialized tools such as wrenches and screwdrivers to operate in the complex outdoor power plant environment. The disassembly and installation of bolts is time-consuming and labor-intensive, and they are prone to jamming or loss in dusty and muddy environments, significantly reducing maintenance efficiency. Especially in large-scale photovoltaic power plants, the workload of replacing roller brushes in batches is enormous, and this cumbersome disassembly and assembly method severely impacts equipment turnover rate and the operation and maintenance costs of photovoltaic power plants.

[0004] Therefore, this utility model proposes a photovoltaic cell module cleaning device to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a photovoltaic cell module cleaning device, which aims to improve the problems of some existing photovoltaic cell module cleaning devices where the cleaning roller brush relies on bolt fixing, resulting in inconvenient assembly, cumbersome disassembly, and low replacement and maintenance efficiency.

[0006] This invention provides a photovoltaic cell module cleaning device, comprising: a body and a cleaning roller brush, wherein the cleaning roller brush is detachably connected to the body.

[0007] It also includes a disassembly mechanism for quickly detaching and installing the cleaning roller brush from the body.

[0012] The locking assembly includes a locking lever and a spring. The locking lever is inserted into the rotating end of the cleaning roller brush, and the spring is used to push the locking lever into the extended and locked position.

[0013] The pull rod is used to abut against the external base block and drive the central main rod to move outward against the elastic force of the spring, so as to drive the clamping rod to retract and separate from the cleaning roller brush.

[0014] Preferably, it also includes a cable and an anti-detachment mechanism, wherein the cable is fixedly connected to the anti-detachment mechanism, and the anti-detachment mechanism is rotatably connected to the machine body to prevent the cable from getting tangled or falling off when the machine body moves.

[0015] Preferably, the anti-fall mechanism includes: a base column fixedly connected to the top of the machine body, and a rotating component rotatably disposed on the base column.

[0016] Preferably, the rotating assembly includes: a turntable rotatably disposed inside the base column, and a connecting plate fixedly connected to the top of the turntable, the top of the connecting plate having a limiting hole for fixing the cable.

[0017] Preferably, the connecting plate is disposed outside the base column, and the turntable and the connecting plate are fixedly connected by a connecting shaft, which is rotatably disposed within the through hole of the base column.

[0018] Preferably, the spring is sleeved on the outer periphery of the central main rod, and the spring is located between the external base block and the locking rod.

[0019] Preferably, the pull rod is rotatably connected to the outer end of the central main rod, and the pull rod has a cam profile, which abuts against the outer surface of the external base block when the pull rod rotates.

[0022] 1. This utility model, by setting up a disassembly mechanism, utilizes the synergistic effect of the pull rod, the central main rod, the external base block and the clamping assembly to solve the problem that the existing technology of cleaning roller brushes are mostly fixed with bolts, which leads to the need to carry tools and the operation being cumbersome and time-consuming when replacing and maintaining them. It achieves the technical effect of quickly disassembling and locking the cleaning roller brush without tools, greatly improving maintenance efficiency and reducing operation and maintenance costs.

[0023] 2. This utility model, by setting an anti-drop mechanism, utilizes a rotatable limiting structure composed of a base column, a turntable, and a connecting plate to solve the problem in the prior art where cables are easily pulled and tangled when the cleaning device moves, leading to connector detachment or fatigue fracture at the cable root, affecting the safe operation of the equipment. It achieves the technical effect of enabling the cable to adapt to the body's movement and rotate, releasing torsional stress, effectively preventing cable detachment and damage, and improving the reliability of equipment operation.

[0034] 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.

[0035] Example:

[0036] Reference Figures 1 to 4This utility model provides a photovoltaic cell module cleaning device, which aims to solve the problems in the prior art where the cleaning roller brush is fixed with bolts, resulting in cumbersome and time-consuming disassembly and assembly, and the cables are prone to tangling or falling off during movement.

[0037] like Figures 1 to 3 As shown, the device includes a body 1 and a cleaning roller brush 2 detachably connected to the front end of the body 1. The body 1 serves as a platform for moving on the surface of a photovoltaic panel. The cleaning roller brush 2 removes dust and dirt from the surface of the photovoltaic panel through rotation. The device also includes a disassembly mechanism 3, located at the front end of the body 1 and used for quick disassembly and assembly of the cleaning roller brush 2 and the body 1. The disassembly mechanism 3 includes an external base block 33 fixedly connected to the outer side of the front end of the body 1. The disassembly mechanism 3 also includes a central main rod 32 axially slidably inserted inside the external base block 33. A pull rod is movably connected to the outer end of the central main rod 32. 31. A clamping assembly 34 is fixedly connected to the inner end of the central main rod 32. The clamping assembly 34 includes a clamping rod 341 and a spring 342. The clamping rod 341 is configured to be inserted into the end of the rotating shaft of the cleaning roller brush 2. The spring 342 is disposed between the outer base block 33 and the clamping rod 341 and is used to push the clamping rod 341 to always maintain the extended locking position to keep the axial limit of the cleaning roller brush 2. The pull rod 31 is configured to rotate to abut against the outer wall of the outer base block 33 and drive the central main rod 32 to move outward against the elastic force of the spring 342, thereby driving the clamping rod 341 to retract synchronously and separate from the cleaning roller brush 2.

[0038] Reference Figure 1 and Figure 4 The anti-detachment mechanism 4 has a base column 41 fixedly connected to the top of the body 1, and a rotating assembly rotatably fitted onto the base column 41. The rotating assembly consists of a turntable 42, a connecting plate 43, and a connecting shaft. The turntable 42 is rotatably disposed in the internal cavity of the base column 41, and the connecting plate 43 is disposed on the upper outer surface of the base column 41. The connecting shaft passes through a through hole at the top of the base column 41 to fix the turntable 42 and the connecting plate 43 together. The anti-detachment mechanism 4 is located at the center of the top of the body 1, and its function is to provide a flexible connection fulcrum for the cable 5 that can move freely in 360 degrees.

[0039] Meanwhile, the connecting plate 43 is correspondingly provided with a limiting hole 44 that penetrates its plate body. In the assembled state, the cable 5 is threaded through and fixed in the limiting hole 44 of the connecting plate 43. This rotating structure of the turntable connecting plate and the base column ensures that when the machine body 1 moves back and forth on the photovoltaic panel for cleaning, the lateral tension on the cable 5 can be converted into the adaptive rotational motion of the connecting plate 43, thereby effectively releasing the torsional stress at the root of the cable 5 and preventing the cable 5 from getting tangled or falling off the machine body 1.

[0040] The diameter of the turntable 42 is designed to be larger than the diameter of the through hole at the top of the base post 41. The inner wall of the top of the base post 41 forms an axial abutment with the upper surface of the turntable 42, thus creating an I-shaped anti-detachment structure. The spring 342 is sleeved on the outer circumferential surface of the central main rod 32, and is located between the outer base block 33 and the locking rod 341. One end of the spring 342 abuts against the inner side wall of the outer base block 33, and the other end abuts against the inner end face of the locking rod 341. The end of the pull rod 31... The part is designed with a cam profile. The pull rod 31 is rotatably connected to the outer end of the central main rod 32 through a pin. When the pull rod 31 is rotated, the cam profile gradually presses against the outer surface of the outer base block 33. Through the squeezing action, the central main rod 32 is forced to move outward. The end of the rotating shaft of the cleaning roller brush 2 is provided with a rotating hole. The diameter of the rotating hole is adapted to the outer diameter of the locking rod 341. When the locking rod 341 extends under the action of the spring 342, the locking rod 341 is tightly inserted into the rotating hole to lock the cleaning roller brush 2.

[0041] The implementation principle of this application embodiment is as follows: When it is necessary to disassemble the cleaning roller brush 2, the operator pulls the pull rod 31, the pull rod 31 rotates and abuts against the external base block 33, the abutting action of the pull rod 31 drives the central main rod 32 to move outward against the elastic force of the spring 342, the central main rod 32 drives the locking rod 341 to retract synchronously and disengage from the cleaning roller brush 2, the cleaning roller brush 2 is unlocked and can be removed, the installation is carried out in reverse, the locking rod 341 is automatically locked under the action of the spring 342, through this cooperative action of the disassembly mechanism 3, this utility model solves the problem of cumbersome and time-consuming disassembly caused by bolt fixing in the prior art.

[0042] When the body 1 moves, the cable 5 will be under tension. Since the cable 5 is fixed to the limiting hole 44 of the connecting plate 43, the tension will drive the connecting plate 43 and the turntable 42 to rotate around the bottom column 41. Through this follow-up rotation of the anti-drop mechanism 4, the torsional stress of the cable 5 is effectively released, preventing the cable 5 from getting tangled or falling off, thus solving the problem of unstable cable connection and easy damage in the prior art.
