Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaner manufacturing technology, and in particular to a highly waterproof and highly stable photovoltaic panel roller brush. Background Technology

[0002] Because photovoltaic panels are exposed to the external environment for extended periods, dust and grime easily accumulate on their surfaces, requiring regular cleaning and maintenance to maintain their performance and effectiveness. Currently, manual cleaning of photovoltaic panels typically uses electric roller brushes, as they generally offer advantages such as good cleaning effect, fast cleaning speed, and relatively simple operation. However, due to their inherent design structure, commercially available photovoltaic panel roller brushes generally suffer from problems such as unstable brush head operation, excessive vibration, poor internal dust and water resistance, and a high failure rate. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a highly waterproof and highly stable photovoltaic panel roller brush to overcome the defects and shortcomings of existing similar products as described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a high-waterproof and high-stability photovoltaic panel roller brush, including a roller brush head, a brush head support frame, a brush rod, a power cord, and a battery. The roller brush head is installed at the head end of the brush head support frame, and the tail end of the brush head support frame is sleeved and fixed to the brush rod. The power cord enters the brush rod from the battery terminal and then enters the brush head support frame. The roller brush head includes a roller and brush strips provided on the surface of the roller. The roller is composed of two symmetrically arranged sub-rollers. An external rotor motor and a fixed sub-shaft tube are coaxially arranged in each sub-roller. At the same time, a radial motor enclosure is integrally formed in each sub-roller. The rotor of the external rotor motor and the motor... The stator of the external rotor motor is fixedly connected to the tail end of the stator shaft tube, and a shaft tube bearing is installed between the stator shaft tube and the inner wall of the sub-roller through a bearing bracket. The brush head support frame has a flat connector, and the head ends of the stator shaft tubes in the two sub-rollers face each other, clamping the flat connector of the brush head support frame between them. The three are fixedly connected by bolts. The power line in the brush head support frame enters the stator shaft tubes in the two sub-rollers through the flat connector and is electrically connected to the stator of the external rotor motor. An inner cover is provided at the inner end of each sub-roller, and the inner cover fits tightly with the inner wall of the sub-roller and the head end of the stator shaft tube.

[0005] Furthermore, the outer wall of the outer rotor of each outer rotor motor is in contact with the inner wall of the sub-roller it is located in.

[0006] To elaborate further, each sub-roller is provided with an outer cover at its outer end, and the outer cover fits tightly with the inner wall of the sub-roller.

[0007] Furthermore, in addition to the flat plate connector, the brush head support frame also has a shock-absorbing and stabilizing cylinder and a tail tube.

[0017] A highly waterproof and highly stable photovoltaic panel roller brush, such as Figures 1 to 5 As shown, it includes a roller brush head 1, a brush head support frame 2, a brush rod 3, a power cord 4, and a battery 5. The roller brush head 1 is installed at the head end of the brush head support frame 2, and the tail end of the brush head support frame 2 is sleeved and fixed to the brush rod 3. The power cord 4 enters the brush rod 3 from the terminal of the battery 5 and then enters the brush head support frame 2. The roller brush head 1 includes a roller and brush strips 1-8 arranged on the surface of the roller. The roller is composed of two symmetrically arranged sub-rollers 1-1. An external rotor motor 1-2 and a stator shaft tube 1-3 are coaxially arranged in each sub-roller 1-1. At the same time, a radial motor enclosure 1-1-1 is integrally formed in each sub-roller 1-1. The rotor of the external rotor motor 1-2 is fixedly connected to the motor enclosure 1-1-1. The stator of the external rotor motor 1-2 is connected to the stator of the external rotor motor 1-2. The tail end of the shaft tube 1-3 is fixedly connected, and the shaft tube bearing 1-5 is installed between the stator shaft tube 1-3 and the inner wall of the sub-roller 1-1 through a bearing bracket 1-4; the brush head support frame 2 has a flat connector 2-1, the head ends of the stator shaft tubes 1-3 in the two sub-rollers 1-1 are opposite each other, and the flat connector 2-1 of the brush head support frame 2 is clamped in it, and the three are fixedly connected by bolts; the power line 4 in the brush head support frame 2 enters the stator shaft tubes 1-3 in the two sub-rollers 1-1 through the flat connector 2-1, and is electrically connected to the stator of the external rotor motor 1-2; an inner cover 1-6 is provided at the inner end of each sub-roller 1-1, and the inner cover 1-6 fits tightly with the inner wall of the sub-roller 1-1 and the head end of the stator shaft tube 1-3.

[0018] Each of the two sub-rollers 1-1 of the roller brush head 1 is driven to rotate by a high-precision coaxially arranged external rotor motor 1-2. The outer wall of the outer rotor of each external rotor motor 1-2 is in close contact with the inner wall of the sub-roller 1-1 it belongs to. This facilitates the improvement of the coaxiality between the sub-roller 1-1 and the external rotor motor 1-2, and also improves the heat conduction (heat transfer to the sub-roller 1-1) performance of the external rotor motor 1-2. The stators of the two external rotor motors 1-2 are securely connected to the flat plate connector 2-1 of the brush head support frame 2 through a precision-machined stator shaft tube 1-3. The (symmetrical) docking, along with the precise placement of the shaft tube bearing 1-5 between the stator shaft tube 1-3 and the sub-roller 1-1, further improves the smoothness of the sub-roller 1-1's rotation around the stator shaft tube 1-3, thereby greatly reducing vibration during operation and minimizing mechanical failures. The motor enclosure 1-1-1 and the precision-machined inner cover 1-6 create a highly dustproof and waterproof internal environment for the sub-roller 1-1, ensuring the stability and reliability of the operation of components such as the outer rotor motor 1-2 and the shaft tube bearing 1-5, and greatly reducing mechanical and electrical failures.

[0019] To further improve the waterproof and dustproof performance of the inside of the roller brush head 1, an outer cover 1-7 is provided at the outer end of each sub-roller 1-1, and the outer cover 1-7 fits tightly with the inner wall of the sub-roller 1-1.

[0020] To further reduce the vibration of the brush head 1 on the brush rod 3 during operation and improve the stability and comfort of the hand grip, the brush head support frame 2, in addition to the flat connector 2-1, also has a shock-absorbing and stabilizing cylinder 2-2 and a tail tube 2-3. The shock-absorbing and stabilizing cylinder 2-2 is located between the flat connector 2-1 and the tail tube 2-3. The tail tube 2-3 is used to connect and fix the brush rod 3. The shock-absorbing and stabilizing cylinder 2-2 to the flat connector 2-1 and the shock-absorbing and stabilizing cylinder 2-2 to the tail tube 2-3 are all fixedly connected by bolts through pre-welded flange rings 2-4, and shock-absorbing sealing gaskets 2-5 are provided between the two flange rings 2-4 of each connection. The shock-absorbing and stabilizing gaskets 2-5 at the connection of the two ends of the shock-absorbing and stabilizing cylinder 2-2 can effectively alleviate and absorb the vibration caused by the operation of the brush head 1, and at the same time play a role in preventing static electricity and preventing dust and sewage from entering the brush head support frame 2.

[0021] See Figure 5 Several sets of axial brush bristle positioning fin pairs 1-1-2 are uniformly formed on the surface of the sub-roller 1-1. Each set of brush bristle positioning fin pairs 1-1-2 consists of 2 fins. The 2 fins of each brush bristle positioning fin pair 1-1-2 cooperate with each brush bristle strip 1-8 to position each brush bristle strip 1-8 by forming a snap-fit ​​with the root of each brush bristle strip 1-8. The purpose and effect of this solution are as follows: First, currently, the brush strips on the surface of the roller are only fixed by adhesive, which is not stable enough. During use, the brush strips are prone to tilting, falling over, or even falling off. Therefore, by forming brush positioning fins 1-1-2 on the surface of the sub-roller 1-1 to interlock with the root of the brush strip 1-8, the stability and long-term uprightness of the brush strip 1-8 on the surface of the sub-roller 1-1 are greatly improved, thereby improving the performance and service life of the brush strip 1-8. Second, forming brush positioning fins 1-1-2 on the surface of the sub-roller 1-1 can improve the mechanical strength of the sub-roller 1-1 and the heat dissipation performance of the surface (increased heat dissipation area), thereby protecting the outer rotor motor 1-2 inside the cavity (the motor needs a lot of heat dissipation during long-term operation).

[0022] The above embodiments are only used to explain the present utility model and are not intended to limit the protection of the present utility model. Any non-substantial modifications made based on the essential solution of the present utility model shall fall within the protection scope of the present utility model.
