Description

Technical Field

[0001] This application relates to the field of photovoltaic panel cleaning technology, and in particular to a photovoltaic panel cleaning device and cleaning robot. Background Technology

[0002] A photovoltaic (PV) panel is a device that converts solar energy into electrical energy. It is mainly composed of photovoltaic cells made of semiconductor materials (such as silicon). When sunlight shines on a PV panel, the semiconductor materials absorb the light energy, excite electrons to generate current, and thus convert the light energy into electrical energy. This electrical energy can be transmitted to the power grid through wires or stored in batteries.

[0003] Because photovoltaic panels are exposed to the outdoors for extended periods, their surfaces often accumulate dust, bird droppings, and other debris, severely affecting their contact with sunlight and consequently impacting their power generation efficiency. Therefore, it is necessary to clean photovoltaic panels.

[0004] Existing cleaning methods mainly involve rinsing with cleaning solutions and brushing. These methods often wash dust and bird droppings from the photovoltaic panels onto the surrounding ground, causing environmental pollution. To avoid this, it is necessary to collect the dust, bird droppings, and other debris from the photovoltaic panels for centralized treatment. Some existing cleaning methods also use vacuum cleaners to collect dust and debris. However, existing vacuum cleaners mainly rely on negative pressure for suction. If the negative pressure is too low, the suction effect is poor; if the negative pressure is too high, the vacuum cleaner may stick to the photovoltaic panels, potentially damaging them. Therefore, a photovoltaic panel cleaning device and a cleaning robot are needed to solve the above problems. Utility Model Content

[0005] The main purpose of this application is to propose a photovoltaic panel cleaning device and cleaning robot, which aims to solve the problem that existing cleaning methods usually cannot collect debris or have poor collection effects.

[0006] To achieve the above objectives, the photovoltaic panel cleaning device and cleaning robot proposed in this application include: a cleaning disc, a first side of which is connected to a drive assembly via a rotating shaft, the drive assembly driving the cleaning disc to rotate, a channel being provided inside the rotating shaft, a first end of which is connected to a suction device, a second end of which extends to a second side of the cleaning disc, the suction device being used to suction dust through the channel, and a plurality of inclined scrapers being provided on the second side of the cleaning disc, the first end of which extends to the channel, the second end of which extends to the edge of the second side of the cleaning disc, the direction in which the second end of the scraper points is the rotation direction of the cleaning disc.

[0007] Optionally, the scraper has an inclined arc-shaped structure, with the concave side of the scraper biased towards the direction of the channel.

[0008] Optionally, a number of bristles are provided on the second surface of the cleaning disc, away from the scraper.

[0009] Optionally, the length of the bristles is greater than the height of the scraper.

[0010] Optionally, an arc-shaped empty area is formed between the concave side of the scraper and the bristles, and the empty area is used for the accumulation and movement of debris.

[0011] Optionally, a plurality of the scraper strips are evenly distributed around the circumference of the channel.

[0012] Optionally, the plurality of the scrapers are detachably connected to the cleaning disc.

[0013] Optionally, the scraper is divided into a connecting part and a cleaning part. An installation groove is formed on the second surface of the cleaning disc corresponding to the scraper. The cross-section of the installation groove and the connecting part is trapezoidal. The connecting part is installed in the installation groove, and the cleaning part is used to clean and guide debris.

[0014] Optionally, notches are provided on the side of the cleaning tray corresponding to the mounting groove, and a fixing part is integrally formed on the second end of the scraper, and the fixing part is fixedly connected to the notch by screws.

[0015] A photovoltaic panel cleaning robot includes a robot body and a photovoltaic panel cleaning device. The robot body includes a moving structure and a robotic arm structure. The photovoltaic panel cleaning device is mounted on the robotic arm structure. The moving structure is used to drive the robot to move, and the robotic arm structure is used to drive the photovoltaic panel cleaning device to move.

[0016] This application's technical solution involves setting up a cleaning disc, with its first surface connected to a drive assembly via a rotating shaft. The drive assembly rotates the cleaning disc. A channel is formed inside the rotating shaft; the first end of the channel is connected to a suction device, and the second end extends to the second surface of the cleaning disc. The suction device is used to remove dust through the channel. Multiple inclined scrapers are arranged on the second surface of the cleaning disc, with the first end of each scraper extending into the channel and the second end extending to the edge of the second surface. The direction pointed to by the second end of the scraper is the rotation direction of the cleaning disc. In use, the rotating cleaning disc will drive the multiple inclined scrapers... The rotating scraper cleans dust and debris from the photovoltaic panel by scraping it. As the scraper rotates, the dust and debris move along its side into the channel and are eventually collected by the suction device, thus preventing dust and debris from polluting the environment. This device collects and guides dust and debris to the channel by rotating the scraper, allowing the suction component to pick up and collect dust and debris with only a small amount of suction. This effectively increases the suction range and effect of the suction component, while also preventing damage to the photovoltaic panel caused by excessive suction. Attached Figure Description

[0029] Existing cleaning methods mainly involve rinsing with cleaning solutions and brushing. These methods often wash dust and bird droppings from the photovoltaic panels onto the surrounding ground, causing environmental pollution. To avoid this, it is necessary to collect the dust, bird droppings, and other debris from the photovoltaic panels for centralized treatment. Some existing cleaning methods also use vacuum cleaners to collect dust and debris. However, existing vacuum cleaners mainly rely on negative pressure for suction. If the negative pressure is too low, the suction effect is poor; if the negative pressure is too high, the vacuum cleaner may stick to the photovoltaic panels, potentially damaging them. Therefore, a photovoltaic panel cleaning device and a cleaning robot are needed to solve the above problems.

[0030] In view of this, this application proposes a photovoltaic panel cleaning device and a cleaning robot.

[0031] In the embodiments of this application, reference is made to Figures 1 to 3 The aforementioned photovoltaic panel cleaning device and cleaning robot include: a cleaning disc 1, the first side of which is connected to a drive assembly (not shown in the figure) via a rotating shaft 2. The drive assembly may specifically include a drive motor and a transmission component. The drive assembly is used to drive the cleaning disc 1 to rotate. A channel 3 is provided inside the rotating shaft 2. The first end of the channel 3 is connected to a suction device (not shown in the figure). The second end of the channel 3 extends to the second side of the cleaning disc 1. The suction device is used to suck up dust through the channel 3. Multiple inclined scrapers 4 are provided on the second side of the cleaning disc 1 (the side opposite to the first side). The first end of the scraper 4 extends to the channel 3, and the second end of the scraper 4 extends to the edge of the second side of the cleaning disc 1. The direction pointed to by the second end of the scraper 4 is the rotation direction of the cleaning disc 1.

[0032] Specifically, when this device is in use, the rotating cleaning disc 1 drives multiple inclined scrapers 4 to rotate. The rotating scrapers 4 can scrape and clean dust and debris on the photovoltaic panel. As the scrapers 4 rotate, the dust and debris will move along the side of the scrapers 4 towards the channel 3, and finally be collected together by the suction device, thus avoiding dust and debris from polluting the environment. This device collects and guides dust and debris to the channel 3 by rotating the scrapers 4, so that the suction component only needs to use a small suction force to suck up and collect the dust and debris. It can effectively increase the dust suction range and effect of the suction component, and at the same time avoid damage to the photovoltaic panel caused by excessive suction force.

[0033] refer to Figure 1 The scraper 4 has an inclined arc-shaped structure, with the concave side of the scraper 4 biased towards the direction of the channel 3. When the scraper 4 rotates, the arc-shaped structure can better guide and push dust and debris to the position of the channel 3.

[0034] refer to Figure 1 and Figure 2On the second surface of the cleaning disc 1, away from the scraper 4, there are several bristles 5. When the cleaning disc 1 rotates or moves, the bristles 5 can clean the surface of the photovoltaic panel, making the cleaning effect of this device better.

[0035] refer to Figure 2 The length of the bristles 5 is greater than the height of the scraper 4. The height of the scraper 4 refers to the distance from the side of the scraper 4 that is in contact with the surface of the photovoltaic panel to the second side of the cleaning disc 1. When the cleaning disc 1 moves toward the surface of the photovoltaic panel, the bristles 5 will first come into contact with the photovoltaic panel. When the scraper 4 comes into contact with the surface of the photovoltaic panel, the bristles 5 will be in a bent and charged state. The bent bristles 5 can better clean the surface of the photovoltaic panel by pressing against the photovoltaic panel.

[0036] refer to Figure 1 and Figure 2 An arc-shaped empty area 6 is formed between the concave side of the scraper 4 and the bristles 5. The empty area 6 is used for the collection and movement of debris. The setting of the empty area 6 can prevent the bristles 5 from obstructing the dust and debris, so that the dust and debris can smoothly pass through the empty area 6 and enter the channel 3.

[0037] refer to Figure 1 Multiple scraper blades 4 are evenly distributed around the channel 3, so that the area between adjacent scraper blades 4 is the same size, that is, the area to be cleaned by each scraper blade 4 is the same, and the dust and debris scraped off are also similar, so that the force on each scraper blade 4 and the cleaning disc 1 is more uniform, thereby extending the service life of the device.

[0038] refer to Figure 2 and Figure 3 Multiple scraper blades 4 are detachably connected to the cleaning disc 1. When a scraper blade 4 is damaged, the corresponding scraper blade 4 can be easily removed and replaced.

[0039] refer to Figure 2 and Figure 3 The scraper 4 is divided into a connecting part 430 and a cleaning part 420. An installation groove 7 is opened on the second surface of the cleaning disc 1 corresponding to the scraper 4. The cross-section of the installation groove 7 and the connecting part 430 is a trapezoidal structure (dovetail groove structure). The connecting part 430 is installed in the installation groove 7. Specifically, one end of the scraper 4 can be inserted into the installation groove 7 from one end, which facilitates the separate installation and removal of the scraper 4. The cleaning part 420 is used to clean and guide debris.

[0040] refer to Figure 3 Notches 8 are provided on the side of the cleaning disc 1 corresponding to the mounting groove 7. The second end of the scraper 4 is integrally formed with a fixing part, which is fixedly connected to the notch 8 by screws 9. When the cleaning disc 1 rotates, it can prevent the scraper 4 from sliding out along the mounting groove 7, making the connection between the scraper 4 and the cleaning disc 1 more stable and reliable.

[0041] For details, please refer to Figure 3 The scraper 4 is made of rubber. In order to make the scraper 4 have good strength, a metal elastic support strip 440 is set in the middle of the scraper 4, so that the scraper 4 has the comprehensive performance of replacement.

[0042] A photovoltaic panel cleaning robot includes a robot body and a photovoltaic panel cleaning device. The robot body includes a moving structure and a robotic arm structure. The photovoltaic panel cleaning device is mounted on the robotic arm structure. The moving structure is used to drive the robot to move, and the robotic arm structure is used to drive the photovoltaic panel cleaning device to move. The robotic arm structure can drive the cleaning device to move in all directions, thereby enabling all-round cleaning of the photovoltaic panel.

[0043] This application's technical solution involves setting up a cleaning disc, with its first surface connected to a drive assembly via a rotating shaft. The drive assembly rotates the cleaning disc. A channel is formed inside the rotating shaft; the first end of the channel is connected to a suction device, and the second end extends to the second surface of the cleaning disc. The suction device is used to remove dust through the channel. Multiple inclined scrapers are arranged on the second surface of the cleaning disc. The first end of each scraper extends into the channel, and the second end extends to the edge of the second surface of the cleaning disc. The direction pointed to by the second end of the scraper is the rotation direction of the cleaning disc. The rotating cleaning disc drives the multiple inclined scrapers to rotate. The rotating scraper can scrape and clean dust and debris from the photovoltaic panel. As the scraper rotates, the dust and debris move along the side of the scraper towards the channel and are finally collected by the suction device, thus preventing dust and debris from polluting the environment. This device collects and guides dust and debris to the channel by rotating the scraper, so that the suction component only needs to use a small amount of suction to pick up and collect the dust and debris. It can effectively increase the dust collection range and effect of the suction component, while also avoiding damage to the photovoltaic panel caused by excessive suction.
