Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic panel cleaning equipment, and in particular relates to an adaptive water circulation negative pressure cleaning robot. Background Art

[0002] Photovoltaic panels are in outdoor environments all year round. Dust is easily adsorbed on the surface of the photovoltaic panels to form a dust layer, which affects the working efficiency of the photovoltaic panels. Therefore, the surface of the photovoltaic panels needs to be cleaned to ensure the working efficiency of the photovoltaic panels.

[0003] During the surface cleaning process of photovoltaic panels, due to the photovoltaic panel body and the use of frames to support the photovoltaic panels during installation, the cleaning vehicle will press the photovoltaic panels to a certain arc when moving on the photovoltaic panels for cleaning. When the cleaning vehicle moves to the junction of two photovoltaic panels, the weight of the cleaning vehicle will cause the junction of the two photovoltaic panels to be staggered, forming a step. When the cleaning vehicle passes by, the cleaning components are likely to collide with the next photovoltaic panel to be cleaned.

[0004] The patent application with application number CN202310793880.1 proposes a photovoltaic panel cleaning device. By reading the application, it can be concluded that it mainly cleans the photovoltaic panel by changing the position of the middle brush roller. During cleaning, the cleaning device is located on the photovoltaic panel. When the cleaning device moves between the two photovoltaic panels, the two photovoltaic panels will be staggered due to gravity, and the brush roller will collide with the photovoltaic panel during the cleaning process, affecting the rotation of the brush roller, thereby causing the cleaning device to jump, causing damage to the cleaning device or making the cleaning work impossible.

[0005] The patent application with application number CN202310608248.5 proposes a photovoltaic panel cleaning device and a method for cleaning photovoltaic panels using the photovoltaic panel cleaning device. By reading the application text and drawings, it can be seen that the application mainly performs cleaning by rotating a cleaning roller, and the vehicle body that drives the cleaning roller to move for cleaning is located on the photovoltaic panel during operation. When cleaning multiple connected photovoltaic panels, misalignment between the photovoltaic panels may occur. The cleaning roller is located at the front end of the vehicle body in the direction of travel, which causes the cleaning roller or the cover on the cleaning roller to first collide with the misalignment between the photovoltaic panels, causing the cleaning work to stop or the cleaning equipment to be damaged. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an adaptive water circulation negative pressure cleaning robot to solve the problem of collision between the cleaning components and the photovoltaic panels during the cleaning process of the connected photovoltaic panels in the current photovoltaic panel cleaning equipment.

[0007] In order to solve the above problems, the present invention adopts the following technical solutions:

[0008] An adaptive water circulation negative pressure cleaning robot includes a body, an adaptive component arranged on the body, and a cleaning component arranged on the adaptive component for cleaning photovoltaic panels. The adaptive component includes a first frame arranged on the body and a guide rod vertically slidably connected to the first frame. The cleaning component is arranged at the bottom end of the guide rod and is located in front of the body.

[0009] Furthermore, the cleaning assembly includes a second frame, a cleaning roller rotatably connected to the second frame, and a driving motor for driving the cleaning roller to rotate. The second frame is connected to the bottom end of the guide roller.

[0010] Furthermore, a spring is sleeved on the guide rod, and the spring is located between the first frame and the second frame.

[0011] Furthermore, the cleaning component also includes a clean water tank, a filter box, a water supply pump, a return water pump and a recovery fan arranged on the vehicle body. A water spray pipe connected to the clean water tank is provided at the front end of the first frame. The clean water tank and the water spray pipe are connected through the water supply pump, and the filter box and the clean water tank are connected through the return water pump. The air inlet of the recovery fan is connected to the second frame and is located above the cleaning roller, and the air outlet of the recovery fan is connected to the water inlet of the filter box.

[0012] Furthermore, the air inlet of the recovery fan is connected to the second frame through a telescopic pipe.

[0013] Furthermore, the outlet of the water spray pipe is provided with a duckbill nozzle, which is arranged at the front end of the first frame.

[0014] Furthermore, there are four guide rods distributed in a rectangular shape, the bottom ends of the four guide rods are connected to the cleaning assembly, and the upper ends of the two guide rods located on the same side of the vehicle body are connected.

[0015] Furthermore, there are two cleaning rollers which rotate relative to each other, the two cleaning rollers are connected by transmission, and the air inlet of the recovery fan is located above the middle of the two cleaning rollers.

[0016] The significant beneficial effects achieved by this utility model are:

[0017] 1. In this application, an adaptive component is installed on the vehicle body to provide the cleaning component with space to move up and down. When the cleaning component encounters an obstacle, it can move upward under the guidance of the adaptive component and automatically fall back after passing the obstacle, effectively solving the problem of the cleaning component colliding with the next photovoltaic panel when passing the junction of two photovoltaic panels.

[0018] 2. The setting of the spring on the guide rod can provide a certain elastic force when the cleaning component moves up, making it easier for the cleaning component to return to its original position.

[0019] 3. The setting of clean water tank, filter box, water supply pump, return water pump, recovery fan and water spray pipe can enable the vehicle to carry water to work, without the need for additional water supply or pre-spraying water. At the same time, the water can be recycled to save water resources.

[0020] 4. The setting of the duckbill nozzle on the water spray pipe can spray water evenly in front of the vehicle body. The duckbill nozzle is installed on the first frame to avoid moving up and down with the cleaning component, which affects the spraying effect.

[0021] 5. There are four guide rods to increase the stability of the cleaning component when it is lifted up and down.

[0022] 6. There are two cleaning rollers that rotate relative to each other, which can throw the sewage upward to the air inlet of the recovery fan for easy recovery. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. 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.

[0029] Example 1

[0030] like Figures 1-4As shown, an adaptive water circulation negative pressure cleaning robot includes a vehicle body 1, an adaptive component installed on the vehicle body 1, and a cleaning component installed on the adaptive component for cleaning photovoltaic panels. The adaptive component includes a first frame 2 installed on the vehicle body 1 and a guide rod 3 vertically slidably connected to the first frame 2. The cleaning component is fixedly installed at the bottom end of the guide rod 3, and the cleaning component is located in front of the vehicle body 1.

[0031] In this embodiment, the cleaning assembly includes a second frame 4, a cleaning roller 5 rotatably connected to the second frame 4, and a drive motor 6 for driving the cleaning roller 5 to rotate. The upper end of the second frame 4 is fixedly connected to the bottom end of the guide roller 3, and the outer circumference of the cleaning roller 5 is surrounded by bristles.

[0032] A spring 7 is sleeved on the guide rod 3, and the spring 7 is located between the bottom end of the first frame 2 and the upper end of the second frame 4. The setting of the spring 7 generates a certain elastic force on the second frame 4 when the second frame 4 moves upward, so that the second frame 4 is in contact with the surface of the photovoltaic panel.

[0033] Working principle: the staff places the vehicle body 1 on the photovoltaic panel that needs to be cleaned, sprays water in front of the vehicle body 1, operates the vehicle body 1 to move and the cleaning roller 5 to rotate to clean the photovoltaic panel. When the vehicle body 1 passes the junction of two photovoltaic panels, the cleaning roller 5 abuts against the next photovoltaic panel to generate an upward force to move the cleaning component upward. The guide rod 3 guides the upward movement of the cleaning component to avoid collision between the cleaning component and the photovoltaic panel, making it convenient for the vehicle body 1 to move between the two photovoltaic panels.

[0034] In combination with the above, in this application, an adaptive component is installed on the vehicle body 1 to provide the cleaning component with space to move up and down. When the cleaning component encounters an obstacle, it can move upward under the guidance of the adaptive component and automatically fall back after passing the obstacle, effectively solving the problem of the cleaning component colliding with the next photovoltaic panel when passing the junction of two photovoltaic panels.

[0035] Example 2

[0036] like Figures 1-4 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. In order to facilitate the movement of the vehicle body 1 on the photovoltaic panel for cleaning, the cleaning assembly also includes a clean water tank 8, a filter box 9, a water supply pump 10, a return water pump 11 and a recovery fan 12 installed on the vehicle body 1. A water spray pipe 13 connected to the clean water tank 8 is installed at the front end of the first frame 2. The water outlet of the clean water tank 8 and the water spray pipe 13 are connected through the water supply pump 10, and the water outlet of the filter box 9 and the clean water tank 8 are connected through the return water pump 11. The air inlet of the recovery fan 12 is connected to the second frame 4 and is located above the cleaning roller 5. The air outlet of the recovery fan 12 is connected to the water inlet of the filter box 9;

[0037] In this embodiment, the water inlet of the water spray pipe 13 is connected to the water outlet of the clean water tank 8, and the water outlet of the water spray pipe 13 is installed with a duckbill nozzle 15, which is installed at the front end of the first frame 2;

[0038] The clean water in the clean water tank 8 is sprayed to the front of the vehicle body 1 through the water supply pump 10 through the water spray pipe 13 and the duckbill nozzle 15 to wet the photovoltaic panel. The vehicle body 1 drives the rotating cleaning roller 5 to move forward to clean the photovoltaic panel. During the rotation of the cleaning roller 5, the sewage is thrown to the air inlet of the recovery fan 12 and is sucked into the filter box 9 by the recovery fan 12. The filtered water in the filter box 9 is returned to the clean water tank 8 through the return pump 11 for recycling. While carrying water for cleaning, the water circulation increases the endurance and saves water resources.

[0039] The duckbill nozzle 15 is installed on the first frame 2 to avoid moving up and down with the cleaning component and affecting the spraying effect.

[0040] Example 3

[0041] like Figures 1-4 As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. In this embodiment, the air inlet of the recovery fan 12 is connected to the second frame 4 through a telescopic pipe 14. The setting of the telescopic pipe 14 can make the recovery fan 12 and the second frame 4 in a flexible connection, avoiding the up and down movement of the second frame 4 affecting the connection with the recovery fan 12.

[0042] There are four guide rods 3 distributed in a rectangular shape. The bottom ends of the four guide rods 3 are connected to the cleaning assembly, and the upper ends of the two guide rods 3 located on the same side of the vehicle body 1 (left and right sides) are connected. The arrangement of the four guide rods 3 increases the stability of the cleaning assembly in lifting and lowering.

[0043] There are two cleaning rollers 5 and they rotate relative to each other. The two cleaning rollers 5 are transmission connected. The drive motor 6 is transmission connected to one of the cleaning rollers 5 to drive the two cleaning rollers 5 to rotate relative to each other. The air inlet of the recovery fan 12 is located above the middle of the two cleaning rollers 5. The relative rotation of the two cleaning rollers 5 can throw the sewage upward to the air inlet of the recovery fan 12, which is convenient for the recovery fan 12 to recover the sewage.
