[0002] Photovoltaic panels are power generation devices that convert light energy into direct current using semiconductor materials. Their core principle is based on the photovoltaic effect, achieving stable power generation through a solid-state structure with no moving parts. They are a crucial component of large-scale photovoltaic (PV) systems. PV panels have a long lifespan and low maintenance costs; once installed, they can operate stably for extended periods, providing a stable power output to the grid. However, PV panels are constantly exposed to the outdoor environment, and their surfaces easily accumulate pollutants such as dust and bird droppings. These pollutants can block sunlight, reduce the power generation efficiency of the PV panels, and in severe cases, even cause overheating, shortening their lifespan. Therefore, regular cleaning of PV panels is essential. Currently, PV panel cleaning relies on spraying water from nozzles set at the factory on a water truck. However, these nozzles cannot reach the top and bottom edges of the PV panels, resulting in insufficient cleaning range and spray pressure. This requires at least two people to work, which is labor-intensive and poses certain safety hazards. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a water truck for cleaning photovoltaic panels. It solves the problems of existing technologies, where the cleaning of photovoltaic panels is carried out by spraying water from nozzles set at the factory. However, the nozzles cannot reach the upper and lower edges of the photovoltaic panels, resulting in unsatisfactory cleaning range and spray pressure. This also requires at least two people to work together, which is labor-intensive and poses certain safety hazards.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In existing technologies, the cleaning of photovoltaic panels is carried out by spraying water from the nozzles set at the factory of the water truck. However, the nozzles cannot reach the upper and lower edges of the photovoltaic panels, and the cleaning range and spray pressure cannot achieve the desired effect. The work requires at least two people, which is labor-intensive and poses certain safety hazards.

[0017] In view of this, the present invention provides a water truck for cleaning photovoltaic panels. Through the cooperation of the vehicle body, water storage tank, extension platform, water outlet pipe, first water supply pipe, first connecting tee, second water supply pipe, first pneumatic ball valve, connecting seat, limit seat, connecting ball head, locking bolt, duckbill nozzle, and camera, and by setting duckbill nozzles on both sides of the rear of the water truck, the cleaning water is sprayed out in a fan shape from the sides of the water truck, ensuring that the cleaning water can evenly cover the surface of the photovoltaic panel, providing a larger cleaning range. The increased spray pressure also covers the upper and lower edges of the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel. Furthermore, there is no need for personnel to control the water flow direction at the rear of the vehicle; the driver can operate the entire cleaning operation from the cab, improving the safety and efficiency of photovoltaic panel cleaning operations.

[0018] Depend on Figure 1-3It is known that a water sprinkler truck for cleaning photovoltaic panels includes a vehicle body 1, a water storage tank 2 fixedly connected to the top of the vehicle body 1, an extension platform 3 located behind the water storage tank 2 on the vehicle body 1, a water outlet pipe 4 located at the bottom of the water storage tank 2, a first water supply pipe 5 located on one side of the extension platform 3, the first water supply pipe 5 being connected to the water outlet pipe 4 via a first connecting tee 6, a second water supply pipe 7 located on the side of the extension platform 3 away from the first water supply pipe 5, the second water supply pipe 7 being connected to the first connecting tee 6, a first pneumatic ball valve 8 installed on the outer wall of both the first water supply pipe 5 and the second water supply pipe 7, and a connecting seat 9 connected to the top of both the first water supply pipe 5 and the second water supply pipe 7. A limiting seat 10 is provided on the side away from each other. The limiting seat 10 is fixedly connected to the connecting seat 9 by locking bolts 12. The inner walls of the connecting seat 9 and the limiting seat 10 are movably connected with connecting ball heads 11. The two connecting ball heads 11 are respectively connected to the first water supply pipe 5 and the second water supply pipe 7. The side of the connecting ball head 11 away from the connecting seat 9 is connected to the duckbill nozzle 13. Cameras 14 are provided on both sides of the top of the water storage tank 2. The cameras 14 are installed on the rear sides of the water storage tank 2 and are connected to the center console in the cab. This allows the operator to see the real-time situation of the cleaning site intuitively through the display screen, so as to react quickly according to the situation and adjust the cleaning strategy.

[0019] In the specific implementation process, it is worth noting that the main structure of the photovoltaic panel cleaning sprinkler truck is formed by the cooperation between the vehicle body 1, the water storage tank 2, and the extension platform 3. The vehicle body 1 is used to carry and support the water storage tank 2 and other cleaning equipment. The water storage tank 2 is used to store the water resources required for cleaning the photovoltaic panels, ensuring that the sprinkler truck has a sufficient water source when carrying out photovoltaic panel cleaning operations. In addition, a water pump system is installed at the bottom of the water storage tank 2 to provide stable water pressure and flow for the cleaning operation. Through the cooperation between the vehicle body 1, the water storage tank 2, the extension platform 3, the water outlet pipe 4, the first water supply pipe 5, the first connecting tee 6, the second water supply pipe 7, and the first pneumatic ball valve 8, the first water supply pipe 5 and the second water supply pipe 7 are located on both sides of the rear of the photovoltaic panel cleaning sprinkler truck. The tee 6 is connected to the outlet pipe 4, and both the first water supply pipe 5 and the second water supply pipe 7 are equipped with a first pneumatic ball valve 8. The first pneumatic ball valve 8 is connected to the vehicle's pneumatic control system and can be independently controlled via a manual controller in the vehicle's cab. The operator can open or close the first pneumatic ball valve 8 via the manual controller in the cab as needed, thereby controlling the water output status of the first water supply pipe 5 and the second water supply pipe 7. This allows for control of the water output status of the first water supply pipe 5 and the second water supply pipe 7 based on the vehicle's driving direction and the layout of the photovoltaic panels, improving the flexibility and efficiency of the cleaning operation. The system includes the first water supply pipe 5, the second water supply pipe 7, the connecting seat 9, the limit seat 10, the connecting ball head 11, the locking bolt 12, and the duckbill spray nozzle. The connection between the heads 13 is achieved by mounting the connecting seat 9 at the top of the first water pipe 5 and the second water pipe 7. The connecting seat 9 and the limiting seat 10 are fixed to the internal connecting ball head 11 by locking bolts 12, thereby fixing the duckbill nozzle 13 at the top of the first water pipe 5 and the second water pipe 7. This allows the cleaning water to be sprayed out in a fan shape, and the angle and direction can be adjusted. The duckbill nozzle 13 can flexibly adjust the spray direction and angle according to the layout and tilt angle of the photovoltaic panel, ensuring that the cleaning water can evenly cover the surface of the photovoltaic panel. Compared with the spray nozzles of the water truck at the factory, it has a larger cleaning range, covering the upper and lower edges of the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel. The camera 14 is installed on both sides of the rear of the water storage tank 2. Connected to the center console in the driver's cab, the system allows operators to visually monitor the real-time situation at the cleaning site via a display screen. This enables them to react quickly and adjust cleaning strategies accordingly. Through the coordination of the vehicle body 1, water tank 2, extension platform 3, water outlet pipe 4, first water supply pipe 5, first connecting tee 6, second water supply pipe 7, first pneumatic ball valve 8, connecting seat 9, limit seat 10, connecting ball head 11, locking bolt 12, duckbill nozzle 13, and camera 14, the system utilizes duckbill nozzles 13 installed on both sides of the rear of the water truck to spray cleaning water in a fan shape from the sides. This ensures that the cleaning water evenly covers the surface of the photovoltaic panels, providing a wider cleaning range. Furthermore, the increased spray pressure ensures coverage of the upper and lower edges of the photovoltaic panels.This improves the cleaning effect of photovoltaic panels, and eliminates the need for personnel to control the water flow direction at the rear of the vehicle. The driver can operate the entire cleaning operation from the cab, improving the safety and efficiency of photovoltaic panel cleaning. The specific models of the first pneumatic ball valve 8 and camera 14 are not limited, as long as they meet the usage requirements.

[0020] Furthermore, a second connecting tee 15 is fixedly connected to the outer wall of the water outlet pipe 4. The top end of the second connecting tee 15 is connected to a third water supply pipe 16. A second pneumatic ball valve 17 is installed on the outer wall of the third water supply pipe 16. The second pneumatic ball valve 17 is used to control the opening and closing of the third water supply pipe 16, thereby controlling the water output of the remote-controlled high-pressure water gun 18. The top end of the third water supply pipe 16 is equipped with a remote-controlled high-pressure water gun 18.

[0021] In the specific implementation process, it is worth noting that the second pneumatic ball valve 17 is connected to the vehicle's pneumatic control system and can be remotely controlled via a manual controller in the vehicle's cab to control the opening and closing of the third water supply pipe 16, thereby controlling the water output of the remote-controlled high-pressure water gun 18. Through the cooperation between the water storage tank 2, the water outlet pipe 4, the second connecting tee 15, the third water supply pipe 16, the second pneumatic ball valve 17, and the remote-controlled high-pressure water gun 18, a remote-controlled high-pressure water gun 18 capable of manual remote control is installed on the top of the extended platform 3 of the water sprinkler truck. The manual controller is located in the vehicle's cab, and the operator can adjust the water pressure and water direction of the remote-controlled high-pressure water gun 18 through the manual controller, so that the operator can use a more concentrated water flow to precisely clean the photovoltaic panels without leaving the cab. This allows the operator to complete the cleaning work more efficiently when encountering stubborn stains or hard-to-reach areas, improving the flexibility and efficiency of cleaning. The specific model of the second pneumatic ball valve 17 is not limited, as long as it meets the usage requirements.

[0022] Furthermore, a water inlet 19 is provided on the top of the water storage tank 2, and an inlet and outlet pipe 20 is connected to the bottom of one side of the water storage tank 2. A first manual ball valve 21 is installed on the outer wall of the inlet and outlet pipe 20.

[0023] In the specific implementation process, it is worth noting that through the cooperation between the water storage tank 2, the water inlet 19, the inlet and outlet pipes 20 and the first manual ball valve 21, the water sprinkler truck can add water to the water storage tank 2 through the water inlet 19 or the inlet and outlet pipes 20. At the same time, the inlet and outlet pipes 20 can also drain water from the water storage tank 2, which makes it convenient for users to flexibly adjust the water volume in the water storage tank 2 according to actual needs, thereby improving the practicality and convenience of the sprinkler truck.

[0024] Furthermore, the bottom of the second water supply pipe 7 is connected to a flexible hose connection pipe 22, and a second manual ball valve 23 is installed on the outer wall of the flexible hose connection pipe 22;

[0025] In the specific implementation process, it is worth noting that, through the cooperation between the second water supply pipe 7, the hose connection pipe 22, and the second manual ball valve 23, by connecting the water supply hose to the hose connection pipe 22, it is convenient for staff to clean the cleaning dead corners of the water sprinkler truck by holding the water supply hose. The water flow of the water supply hose can be controlled by the second manual ball valve 23, which improves the flexibility and convenience of photovoltaic panel cleaning.

[0026] Furthermore, a radar level gauge 24 is installed on the top of the water storage tank 2. The radar level gauge 24 is used to measure the liquid level in the water storage tank 2 and transmit the measurement signal to the control system in the cab in real time.

[0027] In the specific implementation process, it is worth noting that the radar level gauge 24 is used to measure the liquid level in the water storage tank 2 and transmit the measurement signal to the control system in the cab in real time. When the liquid level reaches the preset upper limit or falls below the preset lower limit, it can issue a warning to the operator so that the operator can replenish water or stop the water filling operation in a timely manner according to the liquid level in the water storage tank 2. The specific model of the radar level gauge 24 is not limited, as long as it meets the usage requirements.
