Technical Field

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

[0002] Currently, there are three major pain points in cleaning photovoltaic carports:

[0003] Traditional robots rely on onboard power supplies, resulting in excessive weight.

[0004] Existing cleaning components are not efficient enough at cleaning stubborn stains such as bird droppings and asphalt.

[0005] Large equipment cannot fit into the narrow space of the carport. Utility Model Content

[0006] The purpose of this invention is to provide a photovoltaic cleaning robot to solve the cleaning problem of photovoltaic power stations, such as photovoltaic carports, which are small in area, located high in the ground, and heavily polluted.

[0007] To achieve the above objectives, the present invention provides a photovoltaic cleaning robot, comprising a body, a walking device, a cleaning mechanism, and a driving mechanism. The walking device drives the body to move, and the driving mechanism drives the cleaning mechanism to change position for cleaning operations. The cleaning mechanism is a hydrodynamic disc brush, comprising an impact turbine, a reduction gear transmission device, and a disc brush connected sequentially from top to bottom. The reduction gear transmission device is located on one side of the reducer housing, and at least two nozzles are located on the other side of the reducer housing. The at least two nozzles are sequentially arranged along the semi-circular edge of the impact turbine. The nozzles can drive the rotation of the impact turbine with high-pressure water. The impact turbine drives the disc brush to rotate through the reduction gear transmission device. The reducer housing is connected to the driving mechanism. The hydrodynamic disc brush consumes more than 2 liters and less than 35 liters of water per minute.

[0008] Furthermore, the other side of the reducer housing is provided with an inlet and at least two outlets, the inlet and the outlet are connected, and the nozzle is mounted on the outlet; the positions of the at least two nozzles are all located outside the semi-circular edge of the same side of the impulse turbine near the inlet.

[0009] Furthermore, the number of nozzles on the reducer housing is two or four, the water inlet is located outside between the two or four nozzles, and the water inlet is located on the symmetrical center line between the two or four nozzles.

[0010] Furthermore, the machine body is also equipped with a high-pressure water inlet pipe, which is connected to the water inlet, and the water inlet is connected to the water outlet through an embedded pipe.

[0011] Furthermore, the drive mechanism is an electric push rod, and a lifting block is provided on the top of the drive mechanism, which is connected to the reducer housing.

[0012] Furthermore, the lifting block is connected to the water inlet via a quick connector, and the high-pressure water inlet pipe is connected to the quick connector so that the high-pressure water inlet pipe and the water inlet are connected via the quick connector.

[0013] Furthermore, the cleaning mechanism is located at one or both ends of the front and rear ends of the machine body, and the number of the cleaning mechanism is one, two or four, with the water inlet of two adjacent cleaning mechanisms connected to the same quick connector.

[0014] Furthermore, the cleaning mechanism is located at the front end of the machine body, and a squeegee is provided at the rear end of the machine body.

[0015] Furthermore, the machine body is provided with the walking device at both the left and right ends, and the walking device is a track driven by a motor.

[0016] Furthermore, the photovoltaic cleaning robot is operated by a remote control, and the impact turbine is equipped with a cover on top.

[0017] In summary, the application of the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonable. (1) By setting the body, the body is equipped with a walking device, a cleaning mechanism, and a driving mechanism. The walking device drives the body to walk, and the driving mechanism drives the cleaning mechanism to change position to carry out cleaning operations. Thus, the walking device can be used to drive the body to walk, thereby realizing the walking of the photovoltaic cleaning robot. When the photovoltaic cleaning robot has not reached the area that needs to be cleaned (such as a photovoltaic carport), the driving mechanism can drive the cleaning mechanism to lift up so as to facilitate walking. When the photovoltaic cleaning robot reaches the area that needs to be cleaned (such as a photovoltaic carport), the driving mechanism can drive the cleaning mechanism to descend for cleaning work. (2) By setting the cleaning mechanism as a hydrodynamic disc brush, the cleaning mechanism includes an impact turbine, a reduction gear transmission device, and a disc brush connected sequentially from top to bottom. The reduction gear transmission device is located on one side of the reducer housing, and at least two nozzles are provided on the other side of the reducer housing. At least two nozzles are arranged sequentially along the semi-circular edge of the impact turbine. The nozzles can drive the rotation of the impact turbine through high-pressure water. The impact turbine drives the disc brush to rotate through the reduction gear transmission device. The reducer housing is connected to the drive mechanism. The hydrodynamic disc brush consumes more than 2 liters and less than 35 liters of water per minute. Thus, high-pressure water can be sprayed onto the edge of the impact turbine using at least two nozzles, thereby driving the rotation of the impact turbine. The impact turbine then sequentially drives the reduction gear transmission device and the disc brush. Moreover, at least two nozzles are located on the same side (i.e., on the other side of the reducer housing and located at the semi-circular edge of the impact turbine), thereby reducing the length of the water pipe, making the structure compact, and simplifying the processing technology and structure. As can be seen from the above analysis, this utility model reduces the battery weight of the photovoltaic cleaning robot itself (the cleaning mechanism is driven by high-pressure water power), and the cleaning mechanism has high cleaning efficiency and compact structure, solving the problem of photovoltaic systems on carport roofs being high in location, small in area, heavily polluted, and difficult to clean.

[0027] See Figures 1 to 6This embodiment provides a photovoltaic cleaning robot, including a body 1, a walking device 2, a cleaning mechanism 3, and a drive mechanism 4. The walking device 2 drives the body 1 to move, and the drive mechanism 4 drives the cleaning mechanism 3 to change position to perform cleaning operations. The cleaning mechanism 3 is a water-powered disc brush, which includes an impact turbine 301, a reduction transmission device 302, and a disc brush 303 connected sequentially from top to bottom. The reduction transmission device 302 is located on one side of the reducer housing 304, and at least two nozzles 305 are provided on the other side of the reducer housing 304. The at least two nozzles 305 are arranged sequentially along the semi-circular edge of the impact turbine 301. The nozzles 305 can drive the rotation of the impact turbine 301 through high-pressure water. The impact turbine 301 drives the disc brush 303 to rotate through the reduction transmission device 302. The reducer housing 304 is connected to the drive mechanism 4. The water-powered disc brush consumes more than 2 liters and less than 35 liters of water per minute. Function: (1) By setting the body, the body is equipped with a walking device, a cleaning mechanism, and a drive mechanism. The walking device drives the body to walk, and the drive mechanism drives the cleaning mechanism to change position to perform cleaning operations. Thus, the walking device can be used to drive the body to walk, thereby realizing the walking of the photovoltaic cleaning robot. When the photovoltaic cleaning robot has not reached the area that needs to be cleaned (such as a photovoltaic carport), the drive mechanism can drive the cleaning mechanism to lift up to facilitate walking. When the photovoltaic cleaning robot reaches the area that needs to be cleaned (such as a photovoltaic carport), the drive mechanism can drive the cleaning mechanism to descend for cleaning work. (2) By setting the cleaning mechanism as a hydrodynamic disc brush, the cleaning mechanism includes an impact turbine, a reduction gear transmission device, and a disc brush connected sequentially from top to bottom. The reduction gear transmission device is located on one side of the reducer housing, and at least two nozzles are provided on the other side of the reducer housing. At least two nozzles are arranged sequentially along the semi-circular edge of the impact turbine. The nozzles can drive the rotation of the impact turbine through high-pressure water. The impact turbine drives the disc brush to rotate through the reduction gear transmission device. The reducer housing is connected to the drive mechanism. The hydrodynamic disc brush consumes more than 2 liters and less than 35 liters of water per minute. Thus, high-pressure water can be sprayed onto the edge of the impact turbine using at least two nozzles, thereby driving the rotation of the impact turbine. The impact turbine then sequentially drives the reduction gear transmission device and the disc brush. Moreover, at least two nozzles are located on the same side (i.e., on the other side of the reducer housing and located at the semi-circular edge of the impact turbine), thereby reducing the length of the water pipe, making the structure compact, and simplifying the processing technology and structure. As the above analysis shows, this invention reduces the battery weight of the photovoltaic cleaning robot (the cleaning mechanism is driven by high-pressure water power), and the cleaning mechanism has high cleaning efficiency and a compact structure, solving the problem of difficult cleaning of photovoltaic systems on carport roofs, which are located high, have a small area, are heavily polluted, and are difficult to clean. Calculations show that under suitable working pressure, the flow rate of each nozzle is best between 1 and 3 liters. Therefore, the water consumption of the photovoltaic robot is approximately between 2 and 32 liters.

[0028] Specifically, the other side of the reducer housing 304 is also provided with an inlet 306 and at least two outlets 307. The inlet 306 and the outlets 307 are connected, and nozzles 305 are mounted on the outlets 307. The positions of the at least two nozzles 305 are all located on the outer side of the semi-circular edge of the impulse turbine 301 near the inlet 306. Function: With this arrangement, high-pressure water can enter from the inlet 306 and be uniformly transmitted to multiple outlets 307, and then enter the nozzles 305 from the outlets 307. Moreover, the nozzles of the hydrodynamic brush are all located on the same side near the inlet.

[0029] Specifically, the reducer housing 304 has two or four nozzles 305, and the inlet 306 is located outside between the two or four nozzles 305, on a symmetrical center line between the two or four nozzles 305. Function: See [link / reference] Figure 5 The number of nozzles 305 on each reducer housing 304 is two, see [reference]. Figure 6 Each reducer housing 304 has four nozzles 305. With such a number and distribution, the high-pressure water transmission path can be divided into two, and each transmission path can supply water to one or two nozzles 305, resulting in a compact structure.

[0030] Specifically, the body 1 is also equipped with a high-pressure water inlet pipe 5, which is connected to the water inlet 306. The water inlet 306 is connected to the water outlet 307 through an embedded pipe. Function: The high-pressure water inlet pipe 5 provides high-pressure water, which passes through the water inlet 306 and the water outlet 307 in sequence to reach the nozzle 305. The embedded pipe facilitates water flow.

[0031] Specifically, the drive mechanism 4 is an electric push rod, and a lifting block 401 is provided on the top of the drive mechanism 4. The lifting block 401 is connected to the reducer housing 304. Function: The electric push rod drives the lifting block 401 to move up and down, and the lifting block 401 carries the reducer housing 304 up and down, ultimately realizing the cleaning mechanism lifting up and lowering to perform cleaning work.

[0032] Specifically, the lifting block 401 is connected to the water inlet 306 via a quick connector 6, and the high-pressure water inlet pipe 5 is connected to the quick connector 6, so that the high-pressure water inlet pipe 5 and the water inlet 306 are connected via the quick connector 6. Function: By setting up the quick connector, the cleaning mechanism can be easily disassembled and assembled quickly.

[0033] Specifically, the cleaning mechanism 3 is located at one or both ends of the front and rear of the machine body 1. The number of cleaning mechanisms 3 can be one, two, or four. The water inlets 306 of two adjacent cleaning mechanisms 3 are connected to the same quick connector 6. Function: When multiple cleaning mechanisms 3 are set, more photovoltaic module areas can be cleaned. The specific number and location can be selected according to actual needs.

[0034] Specifically, the cleaning mechanism 3 is located at the front end of the machine body 1, and the rear end of the machine body 1 is equipped with a squeegee 7. Function: The cleaning mechanism 3 cleans at the front, while the squeegee 7 at the rear scrapes away wastewater during forward movement. In practice, four cleaning mechanisms are located at the front end of the machine body, and each cleaning mechanism has 2 to 4 nozzles on the same side. (See [reference]). Figure 5 , Figure 6 .

[0035] Specifically, the left and right ends of the machine body 1 are respectively equipped with a walking device 2, which is a track driven by a motor. Function: The left and right track motors rotate fast / slowly to achieve forward movement, turning, etc.

[0036] Specifically, the photovoltaic cleaning robot is operated by a remote control, and a cover 308 is provided above the impact turbine 301. Functions: The remote control allows for convenient remote control of the photovoltaic cleaning robot's status; the cover 308 serves to guide the water after it has been used down onto the photovoltaic panels and also provides protection.

[0037] Taking the charging carport as an example, its working principle is as follows:

[0038] 1. Remote control signal transmission: When a button or joystick is pressed, the remote control converts the action into a wireless signal and transmits it.

[0039] 2. The vehicle receives the signal: After receiving the signal, the receiver on the vehicle transmits it to the control board.

[0040] 3. Control track movement: The control board adjusts the speed of the left and right track motors according to the signal to achieve forward movement, turning, etc.

[0041] 4. After remote start, the electric push rod adjusts the brush to contact the photovoltaic glass surface. The ground water pump provides a 5MPa high-pressure water flow, which is delivered to the nozzle through the high-pressure water inlet pipe 5. The walking device moves along the surface of the photovoltaic module to complete the cleaning, with a water output of 4 liters per minute (the water-powered brush consumes more than 2 liters of water per minute).

[0042] In summary, this utility model discloses a small and efficient photovoltaic cleaning robot, mainly used to solve the cleaning problems of photovoltaic power stations such as photovoltaic carports, which are small in area, high in location, and heavily polluted. It is a lightweight and expandable remote-controlled vehicle, characterized by having more than one disc brush, operated by a remote control. The disc brush is driven by high-pressure water power, and a high-pressure water pump supplies water and power to the brush head through pipes on the ground. This reduces the battery weight of the remote-controlled vehicle itself and effectively solves the problem of cleaning photovoltaic systems on carport roofs, which are high in location, small in area, heavily polluted, and difficult to clean.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
