Description

Technical Field

[0001] The utility model relates to the technical field of solar panel cleaning devices, and in particular to a solar panel cleaning device. Background Art

[0002] Solar panels are the most important component of solar power generation systems. For large-scale solar panels, in order to better obtain solar energy, the solar panels will be directly exposed. Large-scale solar panels are usually arranged in relatively dry areas with flying sand and dust. After the solar panels have been used for a long time, dust will fall on their surface. The accumulated dust will cause the energy collection rate of the solar panels to decrease, which will directly lead to a decrease in power generation and affect the power generation of the solar panels.

[0003] Solar panels are mostly cleaned manually, which is slow and ineffective. In addition, most solar panels are spliced ​​together and supported diagonally on roofs or in the wild, making them difficult to clean. Existing cleaning devices still leave a lot of water after cleaning, which easily causes secondary dust collection. Utility Model Content

[0004] The utility model provides a solar panel cleaning device to solve the problem that the existing solar panel cleaning device has a poor cleaning effect and residual water easily causes secondary dust collection.

[0005] To achieve the above purpose, the utility model provides the following solutions:

[0006] A solar panel cleaning device comprises a mobile device installed on one side of the solar panel and a cleaning device installed on the mobile end of the mobile device. The cleaning device comprises a brush assembly, a spray assembly and a water absorption assembly respectively located on both sides of the brush assembly.

[0007] The utility model completes the operation process of spraying water, brushing and absorbing attached water at one time through the spray component, the brush component and the water absorption component, which is quick and convenient to clean, improves work efficiency, and at the same time reduces the amount of residual water and reduces the situation of secondary dust collection.

[0008] Furthermore, the moving device includes a driving motor, a screw pair drivingly connected to the output shaft of the driving motor, and a moving connection seat mounted on the screw pair, and the cleaning device is mounted on the moving connection seat. The screw pair has stable transmission and large transmission torque, which can enable the cleaning device to operate stably.

[0009] Furthermore, the moving device also includes a rack arranged parallel to the screw pair, and the moving connecting seat is provided with a transmission gear for meshing with the rack, a first bevel gear coaxial with the transmission gear, and a second bevel gear meshing with the first bevel gear, and the second bevel gear is connected to the brush assembly.

[0010] Through the relative movement of the mobile connecting seat and the rack, the kinetic energy of the mobile connecting seat is transferred to the gear transmission, so that a rotational torque is generated on the second bevel gear, causing the brush assembly to rotate, thereby brushing the surface of the solar panel, making the cleaning effect stronger, and at the same time, there is no need to set up an additional drive motor, reducing the cost of the device.

[0011] Furthermore, the brush assembly includes a first rotating shaft and a brush roller fixedly mounted on the first rotating shaft, the second bevel gear is fixedly mounted on the first rotating shaft, the first rotating shaft and the movable connecting seat are connected via a bearing, and the brush roller contacts the surface of the solar panel.

[0012] The first rotating shaft receives the rotational torque on the second bevel gear, so that the brush roller rotates to achieve the purpose of brushing the surface of the solar panel. The bearing can reduce the friction between the first rotating shaft and the movable connecting seat.

[0013] Furthermore, the movable connecting seat is provided with a through hole for the rack to pass through, the side wall of the through hole is provided with a wedge-shaped groove, the width of the wedge-shaped groove is smaller than the width of the groove bottom, and the side wall of the rack is provided with a wedge block matching the wedge-shaped groove.

[0014] By passing the rack through the inside of the mobile connecting seat and using the wedge groove and the wedge block to cooperate and connect, not only the mobile connecting seat is prevented from rotating, but also shaking between the mobile connecting seat and the rack is prevented to affect the meshing between the gears.

[0015] Furthermore, the transmission gear, the first bevel gear and the second bevel gear are all arranged inside the movable connecting seat, so as to reduce the contact area between each gear and the outside world and increase its service life.

[0016] Furthermore, the first rotating shaft is arranged perpendicularly to the lead screw pair, so that the first rotating shaft sweeps a larger area driven by the movable connecting seat, thereby increasing the cleaning area of ​​the device.

[0017] Furthermore, the spray assembly includes a water pipe with one end fixedly connected to the mobile connecting seat, and a plurality of spray heads installed on the water pipe. A quick connector for connecting to a water source is provided on the end of the water pipe away from the mobile connecting seat, and the spray head is arranged toward the surface of the solar panel.

[0018] The sprinkler head sprays water evenly onto the surface of the solar panel, which not only cleans it but also cools it down and improves its energy conversion efficiency.

[0019] Furthermore, the water absorption component includes a second rotating shaft with one end fixedly connected to the movable connecting seat and a water absorption cotton roller rotatably mounted on the second rotating shaft, and the water absorption cotton roller is in contact with the surface of the solar panel.

[0020] The second rotating shaft moves above the surface of the solar panel under the drive of the movable connecting seat, so that the water-absorbing cotton roller rolls on the surface of the solar panel to absorb the residual water stains.

[0021] Furthermore, the brush assembly, the spray assembly and the water absorption assembly are arranged in parallel in pairs, and are all arranged parallel to the surface of the solar panel.

[0022] One or more technical solutions provided by the utility model have at least the following technical effects or advantages:

[0023] (1) The utility model uses a spraying component, a brush component and a water absorbing component to complete the operation process of spraying water, brushing and absorbing attached water at one time, which is quick and convenient to clean, improves work efficiency, and reduces the amount of residual water and secondary dust collection;

[0024] (2) Through the relative movement of the mobile connecting seat and the rack, the kinetic energy of the translation of the mobile connecting seat is transferred to the gear transmission, so that a rotational torque is generated on the second bevel gear, so that the brush assembly rotates, thereby brushing the surface of the solar panel, making the cleaning effect stronger, and at the same time, no additional drive motor is required, thereby reducing the cost of the device;

[0025] (3) Spraying water in the form of mist onto the solar panel through a sprinkler head can not only improve the cleaning effect of the device, but also cool the solar panel and improve the conversion efficiency of the solar panel;
