Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a sealing mechanism and a photovoltaic panel anti-falling device. Background Art

[0002] Photovoltaic modules are mainly composed of photovoltaic panels and brackets. Photovoltaic panels are also commonly known as solar panels. They are devices that use solar energy to convert into electrical energy. Photovoltaic panels are mainly composed of cells and protective covers that protect the cells. Photovoltaic panels convert light energy into direct current through the photoelectric effect, and then convert it into alternating current through an inverter for use in homes, businesses, industries and other fields.

[0003] In reality, photovoltaic panels may age due to prolonged exposure to ultraviolet rays and high temperatures, causing the edge packaging materials of the photovoltaic panels to age. Aged packaging materials may cause moisture to penetrate into the photovoltaic panels, leading to problems such as cell corrosion and decreased power output. Photovoltaic panels and photovoltaic brackets are usually connected with bolts. In reality, the threads connecting the photovoltaic panels and photovoltaic brackets may become loose due to the influence of wind, causing the photovoltaic panels to shift or even fall off.

[0038] Reference Figure 5-Figure 6, which is the second embodiment of the present utility model. It is different from the previous embodiment in that: the adjusting member 201 includes a connecting plate 201a fixedly connected to the top of the movable plate 102b, and a first threaded rod 201b rotatably connected to the connecting plate 201a, the connecting plate 201a is used to receive the first threaded rod 201b, and the first threaded rod 201b is used to drive the opening member 202 to open and tighten.

[0042] Operation process: When the length of the telescopic plate 102d needs to be adjusted, the first threaded rod 201b is rotated, and the driving plate 202a on the first threaded rod 201b moves on the first threaded rod 201b, and the two connecting rods 202b connected thereto are rotated to drive the two bases 202c to move forward and reversely, so that the two ends of the telescopic plate 102d are telescoped, and the rubber sheet 102e is replaced to adapt to photovoltaic panels 101c of different sizes. When the length of the telescopic plate 102d is adjusted and the corresponding rubber sheet 102e is replaced, the second threaded rod 203c is rotated, and the second vertical plate 203b drives the movable plate 102b to retract on the L-shaped plate 102a as the second threaded rod 203c rotates, so that the receiving plate 102c drives the telescopic plate 102d and the rubber sheet 102e to move, so that the rubber sheet 102e is tightly fitted to the edge packaging of the photovoltaic panel 101c.

[0043] Example 3

[0044] Reference Figure 7, which is the third embodiment of the present utility model. Different from the above embodiments, this embodiment provides a photovoltaic panel anti-falling device, including the above-mentioned sealing mechanism, and also includes a locking assembly 300, including an insert 301 provided on the mounting member 101, inserted into the snap member 302, so that the photovoltaic panel 101c is installed on the bracket 101b, and a snap member 302 provided on the insert 301, which snaps and locks the insert 301.

[0045] Specifically, the insert 301 includes a side panel 301a fixedly connected to one side of the photovoltaic panel 101c, a slot 301b opened on the side panel 301a, a locking box 301c fixedly connected to the bracket 101b, and a second spring 301d fixedly connected to the locking box 301c. The side panel 301a is elastically retractable, and the size of the side panel 301a is adapted to the size of the opening of the locking box 301c. The slot 301b is used to receive the fastener 302. The locking box 301c is fixedly connected to the bracket 101b. The locking box 301c is used to accommodate the fastener 302. The second spring 301d provides thrust for the side panel 301a. There are two side panels 301a, the slot 103b, the locking box 301c and the second spring 301d, and they are symmetrically arranged.

[0046] Furthermore, the latch 302 includes a block 302a rotatably connected to the locking box 301c, a third spring 302b fixedly connected to the locking box 301c, and a pressing rod 302c slidably connected to the locking box 301c. The end of the block 302a is set in the slot 301b, and the other end of the block 302a is fixedly connected to the third spring 302b. The third spring 302b provides thrust for the block 302a, and the pressing rod 302c presses the block 302a to drive the block 302a to rotate. There are two blocks 302a, three springs 302b and pressing rods 302c, and they are symmetrically arranged.

[0047] The rest of the structure is the same as that of Example 2.

[0048] Operation process: When the side plate 301a is tightened and aligned with the opening on the locking box 301c, the side plate 301a is loosened and inserted into the locking box 301c. The insertion of the side plate 301a squeezes the arc surface of the end of the card block 302a, causing the card block 302a to rotate counterclockwise. The second spring 301d is tightened and the third spring 302b is opened. When it is squeezed to a certain extent, under the thrust of the third spring 302b, the card block 302a is stuck in the card slot 301b on the side plate 301a, and the photovoltaic panel 101c is locked through the side plate 301a. The buckle locking effectively improves the stability of the installation of the photovoltaic panel 101c, and the structure inside 301c is not affected by the external environment, preventing the photovoltaic panel 101c from being offset due to wind, thereby causing it to fall off. When it is necessary to cancel the buckle locking of the photovoltaic panel 101c, the pressing rod 302c is pressed, and the pressing rod 302c pushes the block 302a to rotate counterclockwise, the third spring 302b is tightened, and the block 302a cancels the buckle of the slot 301b, and under the thrust of the second spring 301d, the side panel 301a is pushed out.
