A dry and wet self-cleaning photovoltaic module is provided in this example embodiment. Referring to fig. 1 and 2, the photovoltaic module may include a frame 100, a cleaning device 200, a driving device 300, and a control circuit. The frame 100 is used for mounting the photovoltaic module 400, and two opposite sides of the frame 100 are respectively provided with a guide rail 500, wherein one end of the guide rail 500 is bent downwards and extends for a preset length to form a bending section 510. The cleaning device 200 is disposed on the guide rail 500 and above the photovoltaic module 400. The driving device 300 is disposed on the cleaning device 200, and is used for driving the cleaning device 200 to move on the guide rail 500. The control circuit is electrically connected to the driving device 300, and is used for controlling the number of times and duration of operation of the driving device 300 in a preset time period, and controlling the driving device 300 to stop or operate in the bending section 510.
Through the above-mentioned device, the cleaning device 200 moves on the guide rail 500 under the driving of the driving device 300 to clean the foreign dust on the surface of the photovoltaic module 400. On one hand, since one end of the guide rail 500 is bent downwards to extend for a preset length to form the bending section 510, when the cleaning device 200 moves to the bending section 510, the impurity and dust on the photovoltaic module 400 can be conveniently cleaned out, and when the cleaning is completed, the control circuit can control the driving device 300 to stop the cleaning device 200 at the bending section 510, so that the photovoltaic module is prevented from being influenced to receive the sunlight, and the power generation efficiency of the photovoltaic module is further improved; on the other hand, the control circuit can control the operation times and duration of the driving device 300 in a preset time period, which is equivalent to setting the cleaning time and cleaning times of the cleaning device in advance, thereby reducing the probability of manual operation. Therefore, the dry and wet self-cleaning photovoltaic module provided by the embodiment improves the power generation efficiency, reduces the manual consumption and saves the cost.
Next, each part of the above-described dry and wet self-cleaning photovoltaic module in the present exemplary embodiment will be described in more detail with reference to fig. 1 to 3.
In one embodiment, the photovoltaic module 400 is rectangular and is detachably mounted on the frame 100, and the frame on which the photovoltaic module 400 is mounted is also rectangular. The horizontal position of the guide rail 500 disposed on the frame 100 is higher than the horizontal installation position of the photovoltaic module 400, so that the cleaning device 200 is located above the photovoltaic module 400 and can contact the light receiving surface of the photovoltaic module 400 when the cleaning device cleans the surface of the photovoltaic module 400. The guide rails 500 may be disposed on both longer sides of the frame 100 or on both shorter sides of the frame 100, for example, in fig. 1, the guide rails are disposed on both longer sides of the frame 100.
In one embodiment, the bent section 510 of the guide rail 500 is located outside the body of the photovoltaic module 400, so that the cleaning device 200 moving thereto can sweep away the impurity and dust on the photovoltaic module 400, and when the cleaning is stopped, the cleaning device 200 can be stopped at the bent section 510, thereby preventing the photovoltaic module 400 from receiving the sunlight. For example, as shown in fig. 2, the frame 100 is provided with two sides of the guide rail longer than the side length of the photovoltaic module 400, and accordingly, the length of the horizontal section of the guide rail 500 is greater than or equal to the side length of the photovoltaic module 400, so that the bending section 510 is located outside the body of the photovoltaic module 400. In addition, the present disclosure does not limit the bending angle of the bending section 510, and can ensure that the cleaning device 200 moves normally in the section. The predetermined length of the bent section 510 is related to the size of the cleaning device 200, i.e. the length of the bent section 510 is enough to accommodate the cleaning device 200 and ensure that the cleaning device 200 is outside the body of the photovoltaic module 400.
Optionally, in some embodiments, the track 500 is provided with an annular rack 520, and the cleaning device 200 can move along the rack 520. In the present embodiment, as shown in fig. 2, the shape of the ring-shaped rack 520 is similar to the contour shape of the guide rail 500. The cleaning device 200 rotates on the annular rack in a clockwise or counterclockwise direction, when the cleaning device 200 moves to the upper part of the annular rack 520, the cleaning device 200 is not in contact with the light receiving surface of the photovoltaic module 400, when the cleaning device 200 moves to the upper part of the annular rack 520, the cleaning device 200 is in contact with the light receiving surface of the photovoltaic module 400, and simultaneously, the cleaning of the light receiving surface of the photovoltaic module 400 is completed in the process of the movement of the cleaning device 200.
In one embodiment, the cleaning device 200 includes a gear 210 and a cleaning portion 220. The gears 210 are symmetrically disposed on the two guide rails 500, and engaged with the racks 520, and the gears 210 are driven to rotate by the driving device 300. Specifically, the driving device may be a motor, and a rotating shaft of the motor is connected to the gear, and when the rotating shaft rotates, the gear is driven to rotate. The cleaning part 220 is connected between the gears 210 on the two guide rails 500 and moves with the rotation of the gears 210.
In another example, the cleaning part 220 may be located below the driving device 300 and be engaged with the driving device 300. For example, the cleaning part 220 is provided with a latch plate for latching the driving device 300. When the cleaning part 220 is damaged or needs to be replaced for a long time, the cleaning part can be directly taken down without moving the rest parts, so that the cleaning part is convenient and quick.
In one example, at least one water bar 221 is disposed on the cleaning portion 220. The photovoltaic module is usually placed outdoors, and the water bar 221 helps the cleaning part 220 to accumulate a small amount of rainwater or dew, so as to wet the cleaning part 220 more sufficiently, so that the cleaning part 220 can clean the photovoltaic module more cleanly.
Exemplarily, the cleaning portion 220 is made of a water absorbing material, so that external rainwater or dew can be absorbed, the photovoltaic module can be cleaned without additionally providing a water supply device, and the cost is reduced to a certain extent. Specifically, the cleaning portion 220 may be a sponge, a collodion, or the like.
In one embodiment, the control circuit is electrically connected to the driving device 300 for controlling the number and duration of operations of the driving device 300 in a preset time period, and controlling the driving device 300 to stop or operate in the bending section 510. The preset time period and the operation times and duration of the driving device 300 can be set according to actual conditions. For example, in a certain photovoltaic module installation area, the sun can shine on the photovoltaic module at seven morning points, so that the worker can set the preset time period to six to seven points, and the cleaning device works in the time period, so that dew is fully absorbed and the photovoltaic module is not influenced to absorb sunlight. Correspondingly, cleaning is selected once or twice according to the cleaning degree of the photovoltaic module. Therefore, the cleaning device can automatically run and automatically stop within a set time period, and manual operation is saved.
In one embodiment, the photovoltaic module further comprises a battery and another photovoltaic module. The battery is electrically connected with the control circuit and used for providing electric energy for the control circuit, and the other photovoltaic module is electrically connected with the battery and used for charging the battery. Specifically, the battery may be a lithium battery. Therefore, the battery is only needed to be replaced manually under the condition that the lithium battery is damaged, the problem of battery power consumption is not needed to be worried about, and the labor and material cost is further saved.
