Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic panel cleaning equipment, and in particular to a handheld circular photovoltaic panel cleaning device. Background Art

[0002] In the more humid southern regions, due to factors such as natural rainfall, the amount of dust accumulated on the surface of photovoltaic panels is generally less than in the arid northern or western regions. Therefore, in these areas, manually operated handheld cleaning devices are often used to clean photovoltaic panels. Typically, handheld cleaning devices are designed with telescopic handles to improve portability and adapt to different work scenarios, allowing users to adjust the length according to actual conditions.

[0003] However, while this telescopic handle design brings convenience to portability and use, it also comes with certain problems. Specifically, as the handle extends from one end to the other, its diameter tends to gradually decrease. Therefore, the position with the smallest diameter may become the weak link in the entire structure. During actual use, this smaller handle section is prone to greater stress and may bend, deform, or even break. This not only affects cleaning efficiency but also shortens the overall service life of the device. Utility Model Content

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way.

[0031] In the more humid southern regions, due to factors such as natural rainfall, the amount of dust accumulated on the surface of photovoltaic panels is generally less than in the arid northern or western regions. Therefore, in these areas, manually operated handheld cleaning devices are often used to clean photovoltaic panels. Typically, handheld cleaning devices are designed with telescopic handles to improve portability and adapt to different work scenarios, allowing users to adjust the length according to actual conditions.

[0032] However, while this telescopic handle design brings convenience to portability and use, it also comes with certain problems. Specifically, as the handle extends from one end to the other, its diameter tends to gradually decrease. Therefore, the position with the smallest diameter may become the weak link in the entire structure. During actual use, this smaller handle section is prone to greater stress and may bend, deform, or even break. This not only affects cleaning efficiency but also shortens the overall service life of the device.

[0033] Based on this, an exemplary embodiment of the present application provides a handheld circular disc photovoltaic panel cleaning device, which includes a roller brush, a roller brush holder and a handle assembly, and the handle assembly includes multiple groups of detachably connected handle units; in this way, each section of the handle unit can maintain a consistent or nearly consistent diameter, which not only ensures that the entire handle assembly has sufficient rigidity and bending resistance at any length, but also reduces the risk of bending deformation or breakage caused by local diameter being too small, thereby greatly improving the overall life of the equipment; when in use, different numbers of handle units can be freely combined according to actual needs to achieve the ideal total length. With a modular design, the cleaning device can easily adapt to changes in various working environments and conditions, enhancing the flexibility and convenience of use; it is easy to maintain and replace. When a handle unit is worn or otherwise damaged, only that part needs to be replaced instead of the entire handle assembly, which reduces maintenance costs while simplifying the maintenance process.

[0034] An exemplary embodiment of the present application provides a handheld disk photovoltaic panel cleaning device, such as Figure 1As shown, the cleaning device includes a roller brush assembly 100, a roller brush holder 200, and a handle assembly 300. The roller brush assembly 100 is arranged on the roller brush holder 200, and one end of the handle assembly 300 is hinged to the roller brush holder 200. The handle assembly 300 includes multiple groups of detachably connected handle units. In this way, each section of the handle unit can maintain a consistent or nearly consistent diameter, which not only ensures that the entire handle assembly 300 has sufficient rigidity and bending resistance at any length, but also reduces the risk of bending deformation or breakage caused by a local diameter that is too small, thereby significantly improving the overall life of the device. When in use, different numbers of handle units can be freely combined according to actual needs to achieve the ideal total length. With a modular design, the cleaning device can easily adapt to various working environments and changes in conditions, enhancing flexibility and convenience of use. It is easy to maintain and replace. When a handle unit is worn or otherwise damaged, only that part needs to be replaced instead of the entire handle assembly 300, which reduces maintenance costs and simplifies the maintenance process.

[0035] In one embodiment, if Figure 2 As shown, the cleaning device includes two roller brush assemblies 100, which are symmetrically arranged on a roller brush bracket 200. The roller brush assembly 100 includes a bristle fixing plate 101 and a drive unit 102; the drive unit 102 is transmission-connected to the bristle fixing plate 101; the drive unit 102 is preferably a motor, which can realize forward and reverse rotation; in order to prevent dust or moisture from entering the interior of the drive unit 102 during cleaning, the outer cover of the drive unit 102 is provided with a protective cover; bristles are fixedly provided at the bottom of the bristle fixing plate 101. During operation, the two roller brushes rotate in opposite directions. Of course, one roller brush assembly 100 or more than two roller brush assemblies 100 can also be provided to adapt to different working conditions.

[0036] In one embodiment, if Figure 1As shown, the handle assembly 300 includes a first handle unit 301, a second handle unit 302 and a third handle unit 303, and the first handle unit 301, the second handle unit 302 and the third handle unit 303 are connected in sequence; of course, it can also include a fourth handle unit, a fifth handle unit, etc., so as to extend the handle assembly 300. One end of the first handle unit 301 is hinged to the roller brush holder 200 so that the angle between the handle assembly 300 and the roller brush holder 200 can be adjusted during operation to facilitate operation. A first connecting portion 304 is provided on the other end. A second connecting portion 305 is provided on the end of the second handle unit 302 connected to the first handle unit 301, and a first connecting portion 304 is provided on the end connected to the third handle unit 303. A second connecting portion 305 is provided on the end of the third handle unit 303 connected to the second handle unit 302. The first connecting portion 304 and the second connecting portion 305 are threadedly connected. For example, the first connecting portion 304 can be provided with an internal thread, and the second connecting portion 305 can be provided with an external thread. In this way, the first connecting portion 304 and the second connecting portion 305 can be threadedly connected, which facilitates disassembly and installation. When in use, different numbers of handle units can be freely combined according to actual needs. The modular design enables the cleaning device to easily adapt to changes in various working environments and conditions, enhancing flexibility and convenience of use.

[0037] To facilitate control of the drive unit 102, the first handle unit 301, the second handle unit 302, and the third handle unit 303 are each internally provided with mutually compatible plugs or sockets at their connection points, so as to establish an electrical connection with the drive unit 102 via a cable or the like. For example, the first handle unit 301 is internally connected to the drive unit 102 via a cable. A socket is provided at the connection point between the first handle unit 301 and the second handle unit 302, a plug is provided at the corresponding point on the second handle unit 302, and a socket is also provided at the other end of the second handle unit 302. A plug is provided at the connection point between the third handle unit 303 and the second handle unit 302, and the end of the third handle unit 303 is connected to an external power source. When the first, second, and third handle units 301, 302, and 303 are connected in sequence, electrical energy is provided to the drive unit 102. In one embodiment, to facilitate control of the drive unit 102, the third handle unit 303 is provided with control buttons 306, which include forward and reverse rotation buttons and a power switch. During use, the power switch is turned on and the drive unit 400 can be controlled to rotate forward or reverse through the control button 306 .

[0038] An emergency stop button is also provided on the cable near the handle assembly 300. This button can be used to stop the device in an emergency. For example, during use, the operator may hold the extension rod close to the brush head. In this case, the operator's hands are far from the control button 306. In an emergency, the power switch cannot be used to shut off the device. In this case, the emergency stop switch can be used to shut off the device. This provides dual protection between the emergency stop switch and the power switch, allowing the operator to easily turn the device off and on in any situation.

[0039] In one embodiment, if Figure 2 and 3 As shown, the roller brush holder 200 is also equipped with a water pipe assembly, which includes a water inlet 201 and a water outlet 202 located at the top of the roller brush assembly 100. A pipe clamp 307 is detachably mounted on the handle unit. The pipe clamp 307 can clamp the water pipe, which is connected to the water inlet 201 to provide cleaning water to the water pipe assembly. The bristle retaining plate 101 is provided with multiple through slots 103 around its rotation center. Water flowing out of the water outlet 202 can enter the bristles through the through slots 103, thereby improving the cleaning effect.

[0040] In one embodiment, if Figure 4 As shown, the cleaning device also includes a hot spot detection module 400. The hot spot detection module 400 is detachably mounted on the roller brush holder 200, without affecting the cleaning function. The module can detect hot spot damage to the photovoltaic panels by detecting the temperature difference between the photovoltaic panels. When hot spot detection is not required, the hot spot detection module 400 can be removed. When hot spot detection is required, the hot spot detection module 400 can be installed on the roller brush holder 200. When a hot spot is detected, the hot spot detection module will illuminate an alarm light and a buzzer will sound, alerting the operator that there is a problem with the photovoltaic panel, allowing the photovoltaic panel to be repaired in a timely manner.
