Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a photovoltaic de-icing and snow removal spray device. Background Technology

[0002] During daily operation, a large amount of dust accumulates on the surface of photovoltaic panels, causing the surface of the photovoltaic panels to be obscured and seriously affecting the working efficiency of the photovoltaic panels. Therefore, cleaning equipment is used to clean the surface of the photovoltaic panels.

[0003] For example, Chinese patent CN106824883A discloses a photovoltaic module dust removal device, comprising a body, a water tank, a control box, and a remote control panel. The water tank is located at one end of the body, with an inlet pipe on top. A pump base is located inside the water tank, and a pressurized water pump is mounted on the pump base. A water suction pipe connector is located at one end of the pressurized water pump, and a water delivery pipe is located at the other end of the pressurized water pump. A spray pipe with nozzles is located at the end of the water delivery pipe. Mounting frames are located at both ends of the lower part of the body, and drive wheels are mounted on the mounting frames. The advantages are: this dust removal device moves back and forth on the photovoltaic panel via the drive wheels; the pressurized water pump pressurizes the cleaning water, which is then sprayed out through the nozzles to clean the dust on the photovoltaic panel; and the device is remotely controlled via wireless signal, eliminating the need for on-site operator operation, making it convenient and reducing worker workload.

[0004] However, the above-mentioned structure cannot quickly melt snow and ice by spraying water, resulting in a decrease in the power generation capacity of the photovoltaic panels.

[0005] Based on this, this utility model designs a photovoltaic de-icing and snow removal spray device to solve the above problems. Utility Model Content

[0016] Beneficial effects

[0017] When clearing snow and ice, the electric heating wire of the snow and ice removal spray assembly heats the water in the liquid filling assembly. The liquid filling assembly draws the heated water into the spraying assembly and sprays it out to form a mist. At the same time, the moving frame moves the spraying assembly to spray liquid, and the spraying assembly sprays along the surface of the photovoltaic panel. The mist melts the snow and ice on the surface of the photovoltaic panel, which is beneficial for the photovoltaic panel to generate electricity. If there is no water in the liquid filling assembly, the air filling assembly drives air into the liquid filling assembly. The electric heating wire heats the air, and the heated air enters the spraying assembly through the liquid filling assembly and is sprayed out. At the same time, the moving frame moves the spraying assembly to spray hot air, which sprays hot air along the surface of the photovoltaic panel. The hot air melts the snow and ice on the surface of the photovoltaic panel, which is beneficial for the photovoltaic panel to generate electricity. When cleaning dust, the liquid filling assembly draws water into the spraying assembly and sprays it out. At the same time, the moving frame moves the spraying assembly to spray liquid, spraying water along the surface of the photovoltaic panel. The water blows away the dust on the surface of the photovoltaic panel, reducing the impact of dust on the photovoltaic panel's power generation. In summary, this invention is beneficial for de-icing or cleaning photovoltaic panels. Attached Figure Description

[0028] The present invention will be further described below with reference to the embodiments.

[0030] Please refer to the instruction manual appendix. Figure 1-6 A photovoltaic de-icing and snow spraying device includes a movable frame 1 for moving along a photovoltaic panel 3;

[0031] The mobile frame 1 is connected to a snow and ice removal spray assembly 2 for cleaning photovoltaic panels 3 and for snow and ice removal spraying;

[0032] The snow and ice removal spray assembly 2 includes a spraying assembly 21, an air filling assembly 22, a liquid filling assembly 23, and an electric heating wire 24. The liquid filling assembly 23 is fixedly installed at one end of the top of the mobile frame 1. The liquid filling end of the liquid filling assembly 23 is connected to the air filling assembly 22 for air heating. The liquid storage end of the liquid filling assembly 23 is equipped with an electric heating wire 24 for water or air heating. The output end of the electric heating wire 24 is fixedly connected to the spraying assembly 21 for spraying water or air. The spraying assembly 21 is fixedly connected to the mobile frame 1, and the spraying end of the spraying assembly 21 is set towards the photovoltaic panel 3.

[0033] When clearing snow and ice, the electric heating wire 24 of the snow and ice spray component 2 heats the water in the liquid filling component 23. The liquid filling component 23 draws the heated water into the spraying component 21 and sprays it out to form a spray. At the same time, the moving frame 1 moves the spraying component 21 to spray liquid. The spraying component 21 sprays along the surface of the photovoltaic panel 3. The spray melts the snow and ice on the surface of the photovoltaic panel 3, which is beneficial for the photovoltaic panel 3 to generate electricity. If there is no water in the liquid filling component 23, the air filling component 22 drives air into the liquid filling component 23. The electric heating wire 24 heats the air. The heated air enters the spraying component 21 through the liquid filling component 23 and is sprayed out. At the same time, the moving frame 1 moves the spraying component 21 to spray hot air along the surface of the photovoltaic panel 3. The hot air melts the snow and ice on the surface of the photovoltaic panel 3, which is beneficial for the photovoltaic panel 3 to generate electricity.

[0034] When cleaning dust, the liquid filling component 23 draws water into the spraying component 21 and sprays it out. At the same time, the moving frame 1 drives the spraying component 21 to move and spray liquid, spraying water along the surface of the photovoltaic panel 3. The water blows away the dust on the surface of the photovoltaic panel 3, reducing the impact of dust on the power generation of the photovoltaic panel 3.

[0035] In summary, this facilitates the de-icing or cleaning of photovoltaic panel 3;

[0036] The spraying assembly 21 includes a spray hole 211, a mounting base 212, and a U-shaped tube 213. The mounting base 212 is fixedly installed in the bottom of the movable frame 1. The U-shaped tube 213 is installed in the mounting base 212. The bottom of the U-shaped tube 213 has spray holes 211 at equal intervals, and the spray holes 211 are set facing downwards towards the photovoltaic panel 3. The U-shaped tube 213 is connected to the liquid adding assembly 23.

[0037] Hot water enters the U-shaped tube 213 and is then sprayed out from the nozzle 211 to form a mist. At the same time, the moving frame 1 moves the nozzle 211 to spray liquid. The nozzle 211 sprays along the surface of the photovoltaic panel 3, and the mist melts the ice and snow on the surface of the photovoltaic panel 3.

[0038] Hot air enters the U-shaped tube 213 and is then ejected from the nozzle 211. At the same time, the moving frame 1 moves the nozzle 211 to spray hot air. The nozzle 211 sprays hot air along the surface of the photovoltaic panel 3, and the hot air melts the ice and snow on the surface of the photovoltaic panel 3.

[0039] The liquid guide pipe 233 includes a water tank 231, a water pump 232 and a liquid guide pipe 233. The water tank 231 and the water pump 232 are fixedly installed on the top of the mobile frame 1. The output end of the water pump 232 is fixedly connected to the liquid guide pipe 233, and the liquid guide pipe 233 is connected to the U-shaped pipe 213. The water tank 231 is fixedly connected to the input end of the water pump 232 through a pipe. An air filling component 22 is fixedly connected to the water inlet hole opened on the top of the water tank 231.

[0040] The bottom of the pipe connecting the water tank 231 and the water pump 232 is flush with the bottom of the water tank 231.

[0041] The electric heating wire 24 is fixedly installed inside the water tank 231;

[0042] When clearing ice and snow, the electric heating wire 24 of the snow and ice removal spray assembly 2 heats the water in the water tank 231 of the liquid addition assembly 23, and the water pump 232 draws the water in the water tank 231 into the liquid guide pipe 233, and then into the U-shaped pipe 213.

[0043] The gas filling assembly 22 includes a blower 221, a first pipe 222, a support plate 223, a control valve 224, and a second pipe 225. The second pipe 225 is fixedly connected to the water inlet of the water tank 231. The control valve 224 is installed on the second pipe 225. The first pipe 222 is fixedly connected to the top of the second pipe 225. The support plate 223 is fixedly connected to the inner wall of the first pipe 222. The blower 221 is fixedly connected to the support plate 223.

[0044] When the mobile frame 1 is not moving, the control valve 224 is closed to prevent the water in the water tank 231 from evaporating outward through the second pipe 225, which is beneficial for water preservation in the water tank 231;

[0045] When spraying, the control valve 224 opens to facilitate the balancing of air pressure in the water tank 231 and reduce the driving pressure of the water pump 232;

[0046] When adding water, the control valve 224 is opened, and water is added into the first pipe 222, and then enters the water tank 231 along the second pipe 225, which facilitates water addition.

[0047] When the water in the water tank 231 is used up, the control valve 224 opens, the fan 221 drives the outside air into the first pipe 222, and then into the water tank 231 through the second pipe 225. The electric heating wire 24 heats the air flowing in the water tank 231, and the heated air enters the U-shaped pipe 213 through the liquid guide pipe 233.
