Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning, and in particular to a rotating brush head and photovoltaic panel cleaning device. Background Technology
[0002] Dirt on photovoltaic panels can negatively impact the efficiency and performance of photovoltaic power generation systems. Specific hazards include:
[0003] 1. Reduced power generation efficiency: Pollutants such as dust, bird droppings, and leaves can block sunlight from reaching the surface of photovoltaic cells, thereby reducing light absorption and directly leading to a decrease in power generation efficiency. Depending on the degree of pollution, this impact can be quite significant.
[0004] 2. Hot Spot Effect: When parts of a photovoltaic panel are shaded or dirty, a difference in current occurs between these areas and other unaffected areas, causing some cells to overheat and forming so-called "hot spots." This not only further reduces efficiency but can also permanently damage the photovoltaic panel.
[0005] 3. Shortened service life: Long-term exposure to dirty environments may cause photovoltaic panel materials to be corroded or otherwise damaged, thus shortening their normal service life.
[0006] Existing rotating brush heads for cleaning photovoltaic panels use bristles to sweep the panels. The rotating bristles strike the dirt, resulting in a strong ability to remove it. However, using bristles alone cannot completely remove dirt, especially stubborn dirt such as bird droppings. Utility Model Content
[0007] The present invention aims to solve the above problems by providing a rotating brush head and a photovoltaic panel cleaning device, which solves the above problems.
[0008] A rotating brush head includes: a rotating disk, a cleaning disk, and bristles. The cleaning disk is located at the center below the rotating disk and is fixed to the rotating disk. The bristles are fixedly connected to the rotating disk, and multiple clusters of bristles are arranged circumferentially around the axis of the rotating disk and surround the cleaning disk.
[0009] Furthermore, it also includes a connecting device located between the bottom of the rotating disk and the top of the cleaning disk, the cleaning disk being fixedly and detachably connected to the rotating disk via the connecting device.
[0010] Furthermore, the connecting device includes a hook and loop side and a loop side, the hook and loop side being fixedly connected to the bottom of the rotating disk, the loop side being fixedly connected to the top of the cleaning disk, and the hook and loop side being bonded together.
[0011] Furthermore, the cleaning disc is ring-shaped, and the cleaning disc is a scouring pad or fabric.
[0012] Furthermore, multiple clumps of bristles are evenly arranged in a circle around the axis of the rotating disk, with gaps between adjacent clumps of bristles.
[0013] Furthermore, the lower ends of the bristles are inclined in a direction away from the axis of the rotating disk.
[0014] Furthermore, the rotating disk has multiple through holes formed in its center for connection.
[0015] A photovoltaic panel cleaning device using the aforementioned rotating brush head includes: a mounting frame and a motor, wherein the housing of the motor is fixedly connected to the mounting frame, and the output shaft of the motor drives a rotating disk to rotate relative to the mounting frame.
[0016] Furthermore, it also includes a gripping rod, which is fixedly or rotatably connected to the mounting bracket.
[0017] Furthermore, it also includes a pipe having an outlet and an inlet, the outlet of which is located on the front and / or rear side of the rotating disk, and the pipe is fixedly connected to the mounting bracket.
[0018] This utility model has the following advantages:
[0019] 1. Using a combination of brush bristles and a cleaning disc, the brush bristles pre-treat the dirt to break it down and thin it out, and then the cleaning disc polishes it. The combination of the two results in less dirt on the surface of the photovoltaic panel after cleaning, thus improving the cleaning effect.
[0020] 2. The cleaning disc is detachable from the rotating disc. It can be removed and replaced when the cleaning disc gets dirty, which prevents the dirty cleaning disc from contaminating the surface of the photovoltaic panel and also makes it easier to clean the cleaning disc.
[0021] 3. Spraying water or cleaning solution onto the surface of the photovoltaic panel using a pipe can improve the cleaning effect and remove some of the dirt that needs to be dissolved before it can be peeled off. Attached Figure Description

[0031] Example 1:
[0032] like Figures 1 to 3 As shown, a rotating brush head includes: a rotating disk 1, a cleaning disk 2, and bristles 3. The cleaning disk 2 is located in the middle of the lower part of the rotating disk 1. The cleaning disk 2 is fixed to the rotating disk 1. The bristles 3 are fixedly connected to the rotating disk 1. Multiple clusters of bristles 3 are arranged in a circle around the axis of the rotating disk 1 and surround the cleaning disk 2.
[0033] Furthermore, it also includes a connecting device 4, which is located between the bottom of the rotating disk 1 and the top of the cleaning disk 2. The cleaning disk 2 is fixed to and detachably connected to the rotating disk 1 via the connecting device 4. When the cleaning disk 2 becomes dirty, it can be removed from the rotating disk 1 for cleaning or replaced with a new cleaning disk 2.
[0034] Optionally, the connecting device 4 includes a hook and loop fastener 41 and a loop fastener 42. The hook and loop fastener 41 is fixedly connected to the bottom of the rotating disk 1, and the loop fastener 42 is fixedly connected to the top of the cleaning disk 2. The hook and loop fastener 41 and the loop fastener 42 are attached together.
[0035] Optionally, the connecting device 4 includes a clamp head and a clamp seat, which are fixedly connected to the bottom of the rotating disk 1 and the top of the cleaning disk 2, respectively, and are clamped and fixed.
[0036] Furthermore, the cleaning disc 2 is ring-shaped, and the cleaning disc 2 is a scouring pad or fabric. It should be noted that scouring pads have stronger resistance to dirt and are therefore preferred.
[0037] Furthermore, the multiple clumps of bristles 3 are evenly arranged in a circle around the axis of the rotating disk 1, with gaps formed between adjacent clumps of bristles 3.
[0038] Furthermore, the lower end of the bristles 3 is inclined away from the axis of the rotating disk 1, thereby expanding the coverage area of the bristles 3 during cleaning.
[0039] Furthermore, the rotating disk 1 has a plurality of through holes in the middle for connection, the through holes being used to connect with the rotating shaft flange.
[0040] During operation, the rotating disk 1 rotates around its axis, with the lower ends of the cleaning disk 2 and brush bristles 3 both in contact with the photovoltaic panel. As the rotating disk 1 moves radially to clean the photovoltaic panel, the outer brush bristles 3 first sweep away larger contaminants such as dust, while simultaneously breaking up contaminants (such as bird droppings) into smaller pieces through impact, facilitating the subsequent cleaning action of the cleaning disk 2. During the rotation of the brush bristles 3, centrifugal force flings the already detached contaminants out of the cleaning area.
[0041] Afterwards, the inner cleaning disc 2 breaks down the dirt, and the rotating cleaning disc 2 repeatedly polishes the dirt, completely peeling off the small pieces of dirt or the dirt that has been processed or thinned off the surface of the photovoltaic panel.
[0042] The brush bristles 3 and the cleaning disc 2 work together. The brush bristles 3 pre-treat the dirt to break it down and thin it out. Then the cleaning disc 2 polishes it, resulting in a better cleaning effect.
[0043] Example 2:
[0044] like Figure 4As shown, a photovoltaic panel cleaning device using the rotating brush head described in Embodiment 1 includes: a mounting frame 5 and a motor 6. The housing of the motor 6 is fixedly connected to the mounting frame 5, and the output shaft of the motor 6 drives a rotating disk 1 to rotate relative to the mounting frame 5. The output shaft of the motor 6 can be directly fixedly connected to the rotating disk 1; alternatively, the output shaft of the motor 6 can drive a connecting shaft rotatably connected to the mounting frame 5, and the connecting shaft is fixedly connected to the rotating disk 1.
[0045] The motor 6 is powered by a battery or wire that is fixedly connected to the mounting bracket 5.
[0046] Furthermore, it also includes a gripping rod 7, which is fixedly or rotatably connected to the mounting frame 5. The gripping rod 7 (only part of the structure is shown in the figure) is used for hand gripping, and the hand drives the gripping rod 7 to move, thereby driving the mounting frame 5 and the rotating disk 1 to move for cleaning.
[0047] Furthermore, it also includes a pipe 8, which has an outlet and an inlet. The outlet of the pipe 8 is located on the front side and / or rear side of the rotating disk 1, and the pipe 8 is fixedly connected to the mounting bracket 5.
[0048] During the radial movement of the rotating brush head, water or cleaning solution is sprayed from pipe 8. The cleaning disc 2 rotates and polishes the photovoltaic panel with water or cleaning solution attached, completely removing dirt and improving the cleaning effect. It can remove some dirt that needs to be dissolved before it can be peeled off (such as bird droppings).
[0049] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
