Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in FIG. 1 and FIG. 2 , a variable flow rate spraying device on a solar panel includes a mounting frame 1, which is long and has a groove-shaped clamping frame 2 fixed thereon; because the clamping frame 2 is groove-shaped, it can be mounted on the frame of a solar panel 3, so that other devices on the mounting frame 1 can directly correspond to the solar panel 3. The mounting frame 1 is mounted on the long side of the solar panel 3 through the clamping frame 2; the clamping frame 2 or the mounting frame 1 and the frame of the solar panel 3 can be connected by bolts or blocks.

One or more nozzles 4 are installed on the mounting frame 1, and the nozzles 4 face the solar panel 3. The nozzles 4 are commercially available variable flow nozzles 4, so that the flow of the nozzles 4 can be changed. A water pipe 5 is connected to the nozzle 4, and water pipe holes 6 are opened on the front and side of the mounting frame 1. The water pipe 5 enters the interior of the mounting frame 1 through the water pipe holes 6 at the nozzles 4, and passes out from the water pipe holes 6 on the side of the mounting frame 1, so that the water pipe 5 can be piped inside the mounting frame 1, thereby keeping the exterior of the mounting frame 1 clean and tidy.

The mounting frame 1 is also provided with a swing mechanism 7, which drives and connects to a wiper 8; the wiper 8 is placed on the surface of the solar panel 3. The swing mechanism 7 drives the wiper 8 to move back and forth on the surface of the solar panel 3, and cooperates with the nozzle 4 to spray clean water or washing liquid on the solar panel 3, so as to wipe off the stains on the solar panel 3. In actual use, the mounting frame 1 equipped with the wiper 8 and the swing mechanism 7 and the nozzle 4 are both installed on the upper side of the solar panel 3.

The other end of the water pipe 5 is connected to the transfer box 9, in which a water tank 10 and a centrifugal pump 11 are arranged. A water inlet pipe 12 is installed on the water tank 10, and the water inlet pipe 12 passes through the transfer box 9 to connect to the water source, and fills the water tank 10 with external water. The inlet of the centrifugal pump 11 is connected to the water tank 10 through a pipeline, and the outlet of the centrifugal pump 11 is connected to the water pipe 5. The centrifugal pump 11 pumps the water in the water tank 10 into the water pipe 5 and transports it to the nozzle. In order to reduce the burden on the solar panel 3, the transfer box 9 is installed close to the ground, and the front of the transfer box 9 is rotatably connected to the box door 13, which is convenient for inspection and maintenance of the transfer box 9.

The motor of the centrifugal pump 11 is equipped with a frequency converter and is signal-connected to a programmable logic controller. The frequency converter and the motor speed of the centrifugal pump 11 are controlled by the programmable logic controller to change the flow rate of the centrifugal pump 11. A dirt detection system is installed on the solar panel 3, and the dirt detection system is signal-connected to the programmable logic controller; the programmable logic controller is signal-connected to the swing mechanism 7. When it is detected that the dirt on the solar panel surface reaches the set value, the programmable logic controller drives the swing mechanism 7 and the centrifugal pump 11 to work, and adjusts the swing rate and spray flow rate according to the real-time dirt detection results to achieve the effect of saving water and energy. The dirt detection system can be implemented through a color sensor or machine vision.

It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
