Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power station equipment, and in particular to a household power station cleaning and spraying system. Background Technology

[0002] Due to the unique installation method of residential solar power stations and the fact that they generally lack independent cleaning systems, cleaning is difficult to perform on them. Furthermore, some residential solar power stations have limited rooftop installation space, making regular manual or machine cleaning impossible. Therefore, the cleaning of these stations relies heavily on natural rainwater, often resulting in untimely cleaning and consequently, unsatisfactory power generation.

[0003] Chinese utility model patent CN217363012U discloses a rooftop photovoltaic panel spraying system. This utility model includes a water spray pipe and an air spray pipe mounted on the upper part of the photovoltaic panel. The water spray pipe and air spray pipe are arranged in parallel. The water spray pipe is evenly equipped with several water nozzles, and the air spray pipe is evenly equipped with several air nozzles. The water nozzles and air nozzles are staggered. To achieve the functions of cleaning dust and stains on the panel and temperature control, a water mist spraying system is composed of water pipes and specially designed nozzles at a certain spacing; an air blowing system is composed of air pipes and specially designed nozzles at a certain spacing. The water mist spraying system is responsible for spraying water mist with adjustable flow rate and atomization degree onto the panel surface to achieve cleaning and cooling purposes. The air blowing system is responsible for blowing air onto the panel surface; the air pressure is adjustable, and the airflow can assist the water flow in rinsing the panel surface, enhancing the cleaning and cooling effects. The two systems can be used simultaneously or independently. Although the water spray pipe and air jet pipe of this utility model can clean and cool photovoltaic panels, they are fixed installations and cannot be moved during actual cleaning. The cleaning area and cleaning capacity are limited, and they cannot clean the photovoltaic panels in all directions. It is easy to leave cleaning blind spots, which will reduce the working efficiency of the photovoltaic panels that are not effectively cleaned over time. Increasing the number of pipes will increase the difficulty and cost of installation. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a household power station cleaning spray system that offers strong cleaning power, a wide cleaning range, and high work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] This residential power station cleaning spray system includes photovoltaic panels, a mounting plate, and a spray device. The photovoltaic panels are laid on the mounting plate. The spray device includes a motor and two brackets. One end of the motor is connected to a rotating shaft with a gear. A rack, which meshes with the gear, is located on the back of the mounting plate along its length. The two brackets are symmetrically positioned on the left and right sides of the mounting plate. One end of each bracket is rotatably connected to the motor and the rotating shaft, respectively. Each bracket has a limit ring at its other end, within which a spray pipe is fitted. The spray pipe is positioned above the surface of the photovoltaic panel and has spray holes and nozzles. The motor rotates, driving the rotating shaft, which in turn drives the gear and rack to mesh and move the spray device back and forth along the length of the mounting plate. The overall structure is ingeniously designed. By using a motor to drive the gear along the length of the mounting plate and meshing with the rack, the spray pipe moves back and forth above the photovoltaic panel, achieving comprehensive cleaning of the entire photovoltaic panel over a large area.

[0007] Preferably, a spray nozzle is installed inside the spray hole, and a spray nozzle is installed inside the spray shower hole. The spray nozzles and spray shower nozzles are evenly and alternately arranged on the spray pipe, with the spray nozzles located above the spray shower nozzles. The spray pipe has a simple structure, and the alternating arrangement of the spray nozzles and spray shower nozzles can simultaneously flush away stubborn stains on the photovoltaic panel and rinse the surface of the photovoltaic panel, effectively improving cleaning efficiency.

[0008] Preferably, the opening of the spray nozzle gradually decreases to an inverted funnel shape, while the opening of the shower nozzle gradually increases to a funnel shape. This can further improve the cleaning power of the spray nozzle and the shower nozzle.

[0009] Preferably, the limiting ring has a threaded hole, and a limiting bolt is installed in the threaded hole. One end of the limiting bolt is located outside the limiting ring, and the other end abuts against the spray pipe. The limiting ring can limit the spray pipe, and the limiting bolt can further fix the spray pipe, making it easy to adjust the spray angle according to cleaning needs.

[0010] Preferably, the spray pipe includes a spray section and a movable section. The spray section is a rigid pipe, and the movable section is a flexible pipe. The rigid material of the spray section facilitates the use of a limiting ring to limit its movement and prevent misalignment or bending that could affect the water output. The flexible pipe allows the spray pipe to move back and forth along the length of the mounting plate during cleaning.

[0011] Preferably, the sprinkler pipe includes a fixed installation section, which is a PPR pipe covered with insulation cotton. The insulation cotton can insulate the sprinkler pipe in the fixed installation section.

[0012] Preferably, the mounting plate has grooves on both sides, and the bracket has a slider that mates with the groove on the side closest to the mounting plate. When the gear meshes with the rack along the length of the mounting plate, the slider slides along the length of the groove. The sliding fit between the groove and the slider increases the stability of the overall structure, making the spray pipe move more smoothly and steadily when cleaning back and forth along the length of the mounting plate, and preventing jamming.

[0013] Preferably, a water tank is installed at the lower end of the mounting plate, and a filter plate is installed on the upper surface of the water tank. The filter plate is arranged parallel to the photovoltaic panel and located below the photovoltaic panel. A water outlet pipe is connected to the bottom of the water tank. The water tank can collect the dirty water after washing, the filter plate can filter out debris such as leaves that fall on the photovoltaic panel, and the water outlet pipe facilitates the centralized discharge of the dirty water after washing.

[0014] Preferably, the lower end of the spray pipe is equipped with a main valve, a booster pump, a flow regulating valve, and a vent valve in sequence. The booster pump and flow regulating valve can effectively adjust the water flow to achieve the spray range and cleaning intensity, making it highly adaptable.

[0015] This utility model designs a household power station cleaning spray system with an ingenious overall structure. A motor drives a gear along the length of the mounting plate, meshing with a rack and pinion to move the spray pipe back and forth above the photovoltaic panel, thus achieving comprehensive cleaning of the entire photovoltaic panel over a large area. The sliding cooperation between the sliding groove and the slider increases the stability of the overall structure. The alternating arrangement of spray nozzles and scrubbing nozzles further enhances the cleaning intensity. A booster pump and a flow regulating valve effectively adjust the water flow to achieve the desired spray range and cleaning intensity, making it highly adaptable. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] Household power station cleaning sprinkler systems, such as Figure 1-3 As shown, the system includes a photovoltaic panel 1, a mounting plate 2, and a spraying device 3. The photovoltaic panel 1 is laid on the mounting plate 2. The spraying device 3 includes a motor 31 and two brackets 32. One end of the motor 31 is connected to a rotating shaft 33, and a gear 34 is provided on the rotating shaft 33. A rack 21 that meshes with the gear 34 is provided on the back of the mounting plate 2. The rack 21 is arranged along the length of the mounting plate 2. The gear 34 meshes with the rack 21. The two brackets 32 are symmetrically arranged on the left and right sides of the mounting plate 2. One end of the two brackets 32 is rotatably connected to the motor 31 and the rotating shaft 33, respectively. The other end of each of the two brackets 32 is provided with a limit ring 321. A spray pipe 4 is sleeved inside the limit ring 321. The spray pipe 4 is located above the surface of the photovoltaic panel 1. The spray pipe 4 is provided with spray holes and spray nozzles. The rotation of the motor 31 drives the rotating shaft 33 to rotate. The rotation of the rotating shaft 33 drives the gear 34 to mesh with the rack 21 and drives the spraying device 3 to move back and forth along the length of the mounting plate 2. The overall structure is ingeniously designed. The motor 31 drives the gear 34 to mesh with the rack 21 along the length of the mounting plate 2, thereby driving the spray pipe 4 to move back and forth above the photovoltaic panel 1, thus achieving a comprehensive cleaning of the entire photovoltaic panel 1 with a large cleaning range.

[0023] A spray nozzle 41 is installed inside the spray hole, and a spray nozzle 42 is installed inside the spray hole. The spray nozzles 41 and 42 are evenly and alternately arranged on the spray pipe 4, with the spray nozzle 41 located above the spray nozzle 42. The spray pipe 4 has a simple structure, and the alternating arrangement of the spray nozzles 41 and 42 can simultaneously flush away stubborn stains on the photovoltaic panel 1 and rinse the surface of the photovoltaic panel 1, effectively improving cleaning efficiency.

[0024] The opening of the spray nozzle 41 gradually decreases to an inverted funnel shape, while the opening of the spray nozzle 42 gradually increases to a funnel shape. This further enhances the cleaning power of the spray nozzle 41 and the spray nozzle 42.

[0025] The limiting ring 321 has a threaded hole, and a limiting bolt 322 is installed in the threaded hole. One end of the limiting bolt 322 is located outside the limiting ring 321, and the other end abuts against the spray pipe 4. The limiting ring 321 can limit the spray pipe 4, and the limiting bolt 322 can further fix the spray pipe 4, making it easy to adjust the spray angle according to cleaning needs.

[0026] The spray pipe 4 includes a spray section 43 and a movable section 44. The spray section 43 is a rigid pipe, and the movable section 44 is a flexible pipe. The spray section 43 is made of a rigid material, which allows the limiting ring 321 to limit its movement and prevent misalignment or bending that could affect the water output. The movable section 44 is a flexible pipe, which allows the spray pipe 4 to move back and forth along the length of the mounting plate 2 during cleaning. The flexible pipe can be a common telescopic flexible pipe available on the market.

[0027] Both sides of the mounting plate 2 are provided with sliding grooves 22. The bracket 32 ​​is provided with a slider 323 that cooperates with the sliding groove 22 on the side near the mounting plate 2. When the gear 34 meshes with the rack 21 along the length of the mounting plate 2, the slider 323 slides along the length of the sliding groove 22. The sliding cooperation between the sliding groove 22 and the slider 323 increases the stability of the overall structure, making the movement of the spray pipe 4 back and forth along the length of the mounting plate 2 more stable and smooth, and less prone to jamming.

[0028] The lower end of the spray pipe 4 is equipped with a main switch valve 46, a booster pump 47, a flow regulating valve 48, and a vent valve 49 in sequence. The booster pump 47 and the flow regulating valve 48 can effectively adjust the water flow to achieve the spray range and cleaning intensity, making it highly adaptable.

[0029] The working principle of this utility model is as follows: when cleaning of the household power station is required, the main valve 46, the booster pump 47, and the motor 31 are opened. The motor 31 rotates, driving the spray pipe 4 to move back and forth above the photovoltaic panel 1. The spray pipe 4 effectively cleans the photovoltaic panel 1 through the spray nozzles 41 and 42. The spray pipe 4 can also be rotated and fixed by the limit bolt 322 as needed to adjust the spray cleaning angle, or the water volume can be adjusted by adjusting the flow regulating valve 48, thereby adjusting the spray cleaning intensity.

[0030] Example 2

[0031] The difference from Embodiment 1 is that the sprinkler pipe 4 includes a fixed installation section 45, which is a PPR pipe covered with insulation cotton. The insulation cotton can insulate the sprinkler pipe 4 in the fixed installation section 45. The fixed installation section 45 is fixedly installed on the exterior wall of the building.

[0032] Example 3

[0033] The difference from Example 1 is that, as Figure 1 As shown, a water tank 35 is also provided at the lower end of the mounting plate 2, and a filter plate 36 is provided on the upper surface of the water tank 35. The filter plate 36 is arranged parallel to the photovoltaic panel 1 and located below the photovoltaic panel 1. A water outlet pipe 37 is connected to the bottom of the water tank 35. The water tank 35 can collect the dirty water after washing, the filter plate 36 can filter out debris such as leaves that fall on the photovoltaic panel 1, and the water outlet pipe 37 facilitates the centralized discharge of the dirty water after washing.
