Abstract
Description
Technical Field
[0001] The utility model relates to the field of photovoltaic cell texturing technology, in particular to a photovoltaic cell texturing tank self-cleaning cover plate. Background Art
[0002] In the production process of photovoltaic cells, for wet texturing equipment, crystallization is easy to occur inside the machine because of the presence of alkaline gas and acidic gas at the same time. Generally, trough machines use robotic arms to lift and place flower baskets above each trough body, which will inevitably cause the reaction liquid to drip on the trough cover. The long-term accumulation of alkaline salt crystals, complexes and reaction liquid on the trough cover is very difficult to clean, and the weight of the cover is increased. In addition to affecting the quality of the battery cells, there are also safety hazards. Therefore, the machine must be shut down regularly for cleaning or replacement, which increases costs and affects production efficiency. Utility Model Content
[0003] The purpose of the utility model is to provide a photovoltaic cell texturing slot self-cleaning cover plate, which can keep the surface of the slot cover plate clean in real time, reduce the generation of surface crystallization, and improve product quality and safety.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a self-cleaning cover plate of a photovoltaic cell cashmere trough, comprising a cover plate and a stretching mechanism and a brush arranged on the cover plate, the stretching mechanism comprising a stretching drive unit and a traction rope, one end of the brush is hinged to the side of the stretching drive unit, and the other end of the brush is connected to the movable end of the stretching drive unit through the traction rope, and the brush can rotate around the hinge under the drive of the movable end of the stretching drive unit to brush the surface of the cover plate.
[0005] As a further improved technical solution of the utility model, a return spring is further provided at the side hinge between the brush and the stretching drive unit.
[0006] As a further improved technical solution of the utility model, two brushes are symmetrically arranged on the side of the stretching drive unit, and the two brushes brush in opposite directions under the pulling force of the traction rope and the stretching drive unit.
[0007] As a further improved technical solution of the utility model, a water pipe is arranged above the brush, and a water discharge hole is opened on the side wall of the water pipe.
[0008] As a further improved technical solution of the utility model, the diameter of the water outlet hole is 2 mm.
[0009] As a further improved technical solution of the utility model, at least two groups of the stretching mechanisms and brushes are arranged on each cover plate.
[0010] The photovoltaic cell cashmere trough self-cleaning cover plate of the utility model can automatically brush the cover plate to keep the surface clean and reduce the cost of manpower cleaning by arranging a stretching mechanism, a brush and a return spring on the cover plate. A water pipe is also arranged to flush water on the surface of the cover plate to further effectively improve the cleaning ability, prevent crystal formation and enhance safety.

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. For ease of description, the accompanying drawings only show parts related to the utility model rather than all structures.
[0016] Ginseng Figure 1 and Figure 2 As shown, a self-cleaning cover plate of a photovoltaic cell texturing trough of the present embodiment includes a cover plate 1 and a stretching mechanism 2 and a brush 3 arranged on the cover plate 1. The cover plate 1 is opened and closed on the trough body 4. The stretching mechanism 2 includes a stretching drive unit 21 and a traction rope 22. One end of the brush 3 is hinged to the side of the stretching drive unit 21, and the other end of the brush 3 is connected to the movable end 211 of the stretching drive unit 21 through the traction rope 22. Driven by the movable end 211 of the stretching drive unit, the traction rope 22 pulls one end of the brush 3, so that the brush 3 can rotate around the hinge to brush the surface of the cover plate 1. At the same time, a reset spring 5 is also arranged at the hinge between the brush 3 and the side of the stretching drive unit 21. When the stretching mechanism 2 releases the traction rope 22, the brush 3 automatically returns to its position under the restoring force of the reset spring 5, thereby realizing the repeated brushing action of the brush 3.
[0017] The stretching drive unit 21 can use the existing technology, and will not be described here to prevent understanding. For example, the stretching drive unit 21 can use the telescopic cylinder in the existing technology as a driving force, and the traction rope is pulled by the movable end of the stretching drive unit 21 to drive the brush to rotate.
[0018] Furthermore, two brushes 3 are symmetrically arranged on the side of the stretching drive unit 21, and the two brushes 3 perform brushing in opposite directions under the pulling force of the traction rope 22 and the stretching drive unit 21. Figure 3 The tracks a and b in the drawing are shown in FIG. 1 , and at least two sets of stretching mechanisms 2 and brushes 3 are arranged on each cover plate 1 to ensure that the brushing range of the brush 3 can cover all the cover plates.
[0019] In addition, refer to Figure 4 A water pipe 6 is arranged above the brush 3. The water pipe 6 is not longer than the brush 3. A water outlet hole 61 is arranged on the side wall of the water pipe 6. Water in the water pipe 6 flows out from the water outlet hole 61. The water in the water pipe 6 is matched with the brush 3 to clean the surface of the cover plate, and the effect is better. The diameter of the water outlet hole is 2mm.
[0020] The utility model can keep the surface of the cover plate clean by automatically sweeping the brush, and simultaneously a water pipe is arranged to flush water on the surface of the cover plate, thereby further effectively improving the cleaning ability and preventing the formation of crystals.
