Description

Technical Field

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

[0002] Solar photovoltaic panels are a widely used new type of energy device that converts light energy into electrical energy. Due to their working characteristics, they must be installed outdoors to receive sunlight around the clock. At the same time, they also absorb a large amount of dust from the air. Especially in the northwest region, where sandstorms are frequent, snow and dust gradually accumulate, which seriously affects the solar photovoltaic panels' absorption rate of sunlight, thus affecting the efficiency of power generation. Therefore, it is necessary to clean the solar photovoltaic panels regularly. A photovoltaic panel cleaning robot is used to clean the surface of the photovoltaic panels.

[0003] Existing technologies, such as patent CN210253244U, disclose a cleaning device for an automatic photovoltaic panel cleaning robot. This patent employs a first cleaning device and a second cleaning device arranged in parallel. The first cleaning device includes a primary cleaning brush and a scraper. The primary cleaning brush includes a first rotating shaft and at least two sections of roller brush sleeved around the outer periphery of the first rotating shaft. The outer surface of the roller brush is provided with two roller brush strips distributed in a double helix shape. The first rotating shaft is connected to a first driving device. The second cleaning device includes a cylindrical secondary cleaning brush with a second rotating shaft. This utility model device solves the problem that existing photovoltaic panel cleaning robots only use a single, ordinary brush roller, which results in poor cleaning effect when there is a lot of dust on the photovoltaic panel surface or snow accumulation.

[0004] In daily operation, when the equipment is used to clean photovoltaic panels, water stains are easily left on the surface of the panels when the nozzles spray water jets. This can prevent the photovoltaic panels from fully receiving sunlight and reduce their power generation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where equipment is difficult to thoroughly clean water stains, and to propose a cleaning device for a photovoltaic panel cleaning robot.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cleaning device for a photovoltaic panel cleaning robot includes a main body, a transmission head, a connecting frame, a cleaning wheel, and a nozzle. The transmission head is fixedly connected to the upper end of the main body. The connecting frame is located at one end of the main body. The cleaning wheel is located inside the connecting frame. The nozzle is located at the front end of the cleaning wheel. A cleaning device is located inside the connecting frame. The cleaning device includes a connecting head and a connecting block. The connecting block is fixedly connected to the surface of the connecting frame. The connecting head is located below the connecting frame. A cleaning cotton is fixedly connected to the lower end of the connecting head. A connecting rod is fixedly connected to the upper end of the connecting head. A connecting arm is slidably connected to the surface of the connecting rod. A positioning block is fixedly connected to the end of the connecting rod away from the connecting head. A first spring is sleeved on the surface of the connecting rod. The two ends of the first spring are fixedly connected to the surface of the connecting arm and the lower surface of the positioning block, respectively. The connecting arm is engaged with the interior of the connecting block. A locking hole is opened at the end of the connecting arm away from the connecting rod.

[0008] Furthermore, the connecting block has a pull hole inside, and a locking rod is slidably connected inside the pull hole. By setting the locking rod, the connecting arm can be limited, reducing the possibility that the connecting arm may move easily during use, making it difficult to position the connecting rod.

[0009] Furthermore, one end of the lever engages with the inside of the locking hole, and a pull rod is fixedly connected to the end of the lever away from the locking hole. The pull rod facilitates the movement of the lever.

[0010] Furthermore, a second spring is sleeved and connected to the surface of the pull rod. The two ends of the second spring are fixedly connected to the surface of the lever and the inside of the pull hole, respectively. The second spring facilitates the application of a restoring force to the lever.

[0011] Furthermore, a replacement device is provided on the side of the cleaning wheel. The replacement device includes a pressure groove and a pressure hole. The pressure groove is formed on the side of the cleaning wheel, and the pressure hole is formed on the side of the connecting frame.

[0012] Furthermore, a rotating rod is slidably connected inside the pressure groove, and one end of the rotating rod is rotatably connected to the inner wall of the pressure hole. The rotating rod is provided to facilitate the limited rotation of the cleaning wheel.

[0013] Furthermore, a third spring is fixedly connected to the end of the rotating rod away from the pressure hole, and the end of the third spring away from the rotating rod is fixedly connected to the inside of the pressure groove. The third spring is provided to facilitate the application of a restoring force to the rotating rod.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when using the equipment, the user places the equipment on the surface of the photovoltaic panel and then starts the equipment. The main body drives the lower track to move, and water enters the nozzle through the transmission head to spray the surface of the photovoltaic panel. Then, the cleaning wheel cleans the surface of the photovoltaic panel after spraying. Before using the equipment, the user pulls the lever, and the lever moves, causing the locking lever to move. When the locking lever moves, it causes the second spring to deform and generate elastic force, which then locks the connecting arm into the connecting block. Then, the lever is released, and the second spring returns to its original position, fixing the locking lever and the connecting arm. Inside the connecting block, as the equipment moves, the cleaning cotton drives the connecting head to clean the surface of the photovoltaic panel. By setting up a cleaning device, water stains are effectively removed after cleaning, which also serves to remove residual water stains from the surface of the photovoltaic panel by the cleaning nozzle. When the equipment cleans the photovoltaic panel, the nozzle sprays water jets onto the photovoltaic panel, which can easily leave water stains on the surface of the photovoltaic panel, making it difficult for the photovoltaic panel to fully receive sunlight and reducing the power generation of the photovoltaic panel. The cleaning device can effectively remove the residual water stains on the surface of the photovoltaic panel, improving the practicality of the equipment.

[0016] 2. In this utility model, by setting a replacement device, when the cleaning wheel is replaced, the user presses the rotating rod, and the rotating rod moves, causing the third spring to deform and generate elastic force. Then the rotating rod disengages from the inside of the pressure hole, and the cleaning wheel is unrestrained and can be replaced. By setting a replacement device, the cleaning wheel can be replaced quickly, which reduces the need for tools to install and remove the cleaning wheel from the equipment. The cleaning wheel is usually installed with bolts to the connecting frame. The use of tools is too cumbersome and causes low work efficiency for the replacement personnel. The replacement device can quickly replace the cleaning wheel and improve the practicality of the equipment. Attached Figure Description

[0024] The specific structure and function of the cleaning device 6 and the replacement device 7 will be described in detail below.

[0025] In this embodiment: a cleaning device 6 is provided inside the connecting frame 3. The cleaning device 6 includes a connector 61 and a connecting block 67. The connecting block 67 is fixedly connected to the surface of the connecting frame 3. The connector 61 is located below the connecting frame 3. A cleaning cotton 62 is fixedly connected to the lower end of the connector 61. A connecting rod 63 is fixedly connected to the upper end of the connector 61. A connecting arm 66 is slidably connected to the surface of the connecting rod 63. A positioning block 64 is fixedly connected to the end of the connecting rod 63 away from the connector 61. A first spring 65 is sleeved and connected to the surface of the connecting rod 63. The two ends of the first spring 65 are fixedly connected to the surface of the connecting arm 66 and the lower surface of the positioning block 64, respectively. The connecting arm 66 is engaged with the inside of the connecting block 67. A locking hole 69 is opened at the end of the connecting arm 66 away from the connecting rod 63.

[0026] Specifically, the connecting block 67 has a pull hole 68 inside, and a locking rod 610 is slidably connected inside the pull hole 68.

[0027] In this embodiment: by setting the locking rod 610, the connecting arm 66 can be limited, which reduces the possibility that the connecting arm 66 may move easily during use, making it difficult for the connecting arm 66 to be positioned by the connecting rod 63.

[0028] Specifically, one end of the locking rod 610 is engaged with the inside of the locking hole 69, and the end of the locking rod 610 away from the locking hole 69 is fixedly connected to a pull rod 612. The pull rod 612 is provided to facilitate the movement of the locking rod 610.

[0029] Specifically, a second spring 611 is sleeved and connected to the surface of the pull rod 612. The two ends of the second spring 611 are fixedly connected to the surface of the clamp rod 610 and the inside of the pull hole 68, respectively. The second spring 611 is provided to facilitate the application of a reset force to the clamp rod 610.

[0030] In this embodiment: a replacement device 7 is provided on the side of the cleaning wheel 4. The replacement device 7 includes a pressure groove 71 and a pressure hole 72. The pressure groove 71 is opened on the side of the cleaning wheel 4, and the pressure hole 72 is opened on the side of the connecting frame 3.

[0031] Specifically, a rotating rod 73 is slidably connected inside the pressure groove 71. One end of the rotating rod 73 is rotatably connected to the inner wall of the pressure hole 72. The rotating rod 73 is provided to facilitate the limited rotation of the cleaning wheel 4.

[0032] Specifically, a third spring 74 is fixedly connected to the end of the rotating rod 73 away from the pressure hole 72. The end of the third spring 74 away from the rotating rod 73 is fixedly connected to the inside of the pressure groove 71. The third spring 74 is provided to facilitate the application of a restoring force to the rotating rod 73.

[0033] Working principle: When using the equipment, the user places it on the surface of the photovoltaic panel and starts the equipment. The main body 1 moves the lower track, and water enters the nozzle 5 through the transmission head 2 to spray the surface of the photovoltaic panel. Then, the cleaning wheel 4 cleans the surface of the photovoltaic panel after spraying. Before using the equipment, the user pulls the lever 612, which moves the locking lever 610. When the locking lever 610 moves, it causes the second spring 611 to deform and generate elastic force, which then locks the connecting arm 66 into the connecting block 67. Then, the user releases the lever 612, and the second spring 611 returns to its original position, moving the locking lever 610. 10 is fixed inside the connecting arm 66 and the connecting block 67. When the equipment moves, the cleaning cotton 62 drives the connecting head 61 to clean the surface of the photovoltaic panel. By setting the cleaning device 6, the water stains after cleaning are effectively removed, which plays the role of cleaning the water stains left on the surface of the photovoltaic panel by the cleaning nozzle 5. When the equipment cleans the photovoltaic panel, the nozzle 5 sprays water jets onto the photovoltaic panel, which can easily leave water stains on the surface of the photovoltaic panel. This can make it difficult for the photovoltaic panel to fully receive sunlight and reduce the power generation of the photovoltaic panel. The cleaning device 6 can effectively clean the water stains left on the surface of the photovoltaic panel, improving the practicality of the equipment.

[0034] When replacing the cleaning wheel 4, the user presses the rotating rod 73, which moves and causes the third spring 74 to deform and generate elastic force. The rotating rod 73 then disengages from the pressure hole 72, and the cleaning wheel 4 is released from its restraint, allowing for replacement. The replacement device 7 effectively and quickly replaces the cleaning wheel 4, reducing the inefficiency caused by the fact that the cleaning wheel 4 is typically bolted to the connecting frame 3, requiring tools for installation and removal. The replacement device 7 allows for rapid replacement of the cleaning wheel 4, improving the equipment's practicality.
