Description

Technical Field

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

[0002] The utility model patent application number is 202323305843.6, which discloses a self-cleaning device for photovoltaic panels. The device comprises a frame, a photovoltaic panel is mounted within the frame, and supports are fixed at the four corners of the frame. A screw is mounted between one set of supports, one end of the screw is connected to a motor, a screw block is sleeved on the screw, and a guide rod is mounted between another set of supports. The beneficial effect is that the utility model is provided with an electrostatic generator, an electrostatic adsorption plate, a vibrator, a damping rod, and a spring. The electrostatic generator causes the surface of the electrostatic adsorption plate to carry static electricity, thereby adsorbing and transferring dust on the surface of the photovoltaic panel. This not only achieves self-cleaning of the photovoltaic panel, but also adopts a contactless cleaning method, which can effectively protect the surface of the photovoltaic panel and ensure its service life. At the same time, the vibrator can achieve self-cleaning of the electrostatic adsorption plate. The combination of the damping rod and the spring can reduce the impact on the moving mechanism during vibration, which can effectively improve the use effect of the device.

[0003] The above device has the following disadvantages: the electrostatic adsorption plate is always oriented toward the photovoltaic panel, which means that when the electrostatic adsorption plate is damaged and needs maintenance, the operator needs to bend over and look up to maintain the electrostatic adsorption plate, which increases the difficulty of maintenance.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "embodiment" as used herein refers to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example

[0030] Reference Figure 1-Figure 5This embodiment provides a photovoltaic device panel cleaning device, including a bracket 1, which is provided with a photovoltaic panel 2; a moving mechanism is provided on one side of the top of the bracket 1, and the output end of the moving mechanism is a slider 3, which is rotatably connected to a rotating shaft 1 4, and the rotating shaft 1 4 is fixedly connected to one end of a cleaning box 5, and the other end of the cleaning box 5 is fixed to a rotating shaft 2 6, and the rotating shaft 1 4 and the rotating shaft 2 6 are coaxially arranged, and the rotating shaft 2 6 is fixed to one end of an extension rod 7, and an electrostatic adsorption plate 8 is provided at the bottom of the cleaning box 5;

[0031] A fixing plate 9 is provided on the other side of the top of the bracket 1. The fixing plate 9 has a guide hole. The guide hole includes a straight line segment 10 parallel to the photovoltaic panel 2 and a straight line segment 2 11 perpendicular to the straight line segment 10. The straight line segment 10 is connected to the straight line segment 2 11. The other end of the extension rod 7 slides along the guide hole, and the straight line segment 2 11 is above the straight line segment 10. Figure 1 and Figure 2 As shown, the other end of the extension rod 7 is tilted upward, and correspondingly, the end of the second straight segment 11 away from the first straight segment 10 is tilted upward;

[0032] In this embodiment, when the photovoltaic panel 2 needs to be cleaned, the moving mechanism is operated to move the slider 3 and the cleaning box 5 along the photovoltaic panel 2. During this process, the other end of the extension rod 7 slides along the straight segment 10 of the guide hole. Since the straight segment 10 is parallel to the photovoltaic panel 2, it will not affect the angle of the cleaning box 5. The electrostatic adsorption plate 8 always faces the photovoltaic panel 2 to adsorb impurities. When the electrostatic adsorption plate 8 needs to be cleaned, the moving mechanism is operated to move the other end of the extension rod 7 to the straight segment 2 11. Since the straight segment 2 11 is perpendicular to the straight segment 10, the cleaning box 5 rotates counterclockwise while continuing to move. When the cleaning box 5 rotates, the other end of the extension rod 7 slides along the straight segment 2 11; when the cleaning box 5 reaches the appropriate angle, the moving mechanism is stopped. At this time, the electrostatic adsorption plate 8 can face the operator, and the operator can perform maintenance in a more comfortable posture, thereby improving maintenance efficiency.

[0033] As a preferred solution of the present invention, a guide shaft 12 is fixed to the other end of the extension rod 7, and the guide shaft 12 passes through the guide hole, and a bearing is fixed to the guide shaft 12, and the outer ring of the bearing is in contact with the inner wall of the guide hole. Through the above method, the other end of the extension rod 7 is slidably connected to the guide hole, and under the action of the bearing, the wear on the guide shaft 12 is reduced.

[0034] As a preferred solution of the present invention, the moving mechanism includes a screw rod 13 rotatably connected to the bracket 1, and the screw rod 13 is threadedly connected to the slider 3; the slider 3 is slidingly connected to the track 14 on the bracket 1, and a motor is installed at the end of the screw rod 13, which drives the screw rod 13 to rotate. Since the screw rod 13 and the slider 3 are threadedly connected, the slider 3 is slidingly connected to the track 14 on the bracket 1, so when the motor drives the screw rod 13 to rotate, it can drive the slider 3 to move.

[0035] As a preferred solution of the present invention, the cleaning box 5 is hollow inside and has an opening at the bottom, the electrostatic adsorption plate 8 is slidably connected to the inner cavity of the cleaning box 5, and connecting plates 15 are fixed on both sides of the electrostatic adsorption plate 8. Figure 1 As shown, the single-sided connecting plate 15 is composed of two pieces, one side of the connecting plate 15 contacts the side of the cleaning box 5, an electrostatic generator 18 is installed in the cleaning box 5, and a vibration motor 19 is installed in the cleaning box 5; it also includes a clamping mechanism for clamping the position of the connecting plate 15, more specifically, the clamping mechanism includes a bearing seat fixedly connected to the cleaning box 5, there are two bearing seats, and the bearing seat is rotatably connected to a screw rod 2 16. In order to make the two screw rods 2 16 rotate synchronously, the two screw rods 2 16 are connected by a chain and a sprocket. The screw rod 2 16 has positive and negative threads, and the positive and reverse threads are both threadedly connected to a clamping plate 17; the bearing seat is fixed with an optical axis, and the optical axis is slidably connected to the clamping plate 17; when the above device is in use, the screw rod 2 16 is rotated, and with the cooperation of the optical axis, the two clamping plates 17 are driven to move in the opposite direction, thereby releasing the connecting plate 15, and the distance between the electrostatic adsorption plate 8 and the photovoltaic panel 2 can be manually adjusted to achieve the best adsorption performance;

[0036] The static electricity generator 18 controls whether the static electricity adsorption plate 8 generates static electricity. After the adsorption is completed, the vibration motor 19 can be turned on to make the impurities separate from the static electricity adsorption plate 8.

[0037] As a preferred solution of the present invention, the connection between the straight line segment 10 and the straight line segment 2 11 is chamfered to prevent jamming.

[0038] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made.
