Further, as shown in Figures 6 and 7, support structures 5 are slidably installed on both sides of the bottom of the inverter box 1. A pressure block 502 is slidably installed at the top of the support structure 5. The bottom of the inner cavity of the support structure 5 A pair of supporting legs 503 are installed symmetrically. The tops of the supporting legs 503 are overlapped with bumps 505. Return springs 504 are provided on both sides of the bottom of the bump 505. The return springs 504 support the bumps 505. The inverter box 1 A pair of support plates 501 and blocking rods 506 are symmetrically installed in the middle of the bottom end. The side of the pressure block 502 is slidably connected to the blocking rods 506 and is located outside the supporting plate 501. When the heat dissipation structure 3 moves outward, it will pull the supporting structure. 5 moves outward simultaneously. When the heat dissipation structure 3 is completely pulled out, the pressure block 502 inside the support structure 5 is blocked by the gear rod 506 and will squeeze the bump 505 downward. At this time, the support leg 503 will extend downward. , thereby supporting the ground, and further supporting the heat dissipation structure 3, so that when the seat plate 301 is under pressure, both its inner and outer ends have stress points, thereby preventing the seat plate 301 from bending, and at the same time preventing the equipment from being When pressed, the inner end of the pressure block 502 is supported by the support plate 501 when retracted.

The bottom of the transmission rod 703 is fixedly connected to a cam 704. The cam 704 is attached to the outside of the positioning structure 8. During the process of pulling the heat dissipation structure 3 outward, when the limit rod 206 drops into the support leg 503, the side plate 2 will automatically rotate under the action of the torsion spring and pull the driving gear 701 to rotate, thereby causing the transmission The gear 702 pulls the cam 704 to rotate. During the rotation of the cam 704, the positioning structure 8 will move outward under the support of the support spring 801. At this time, the connecting rod 303 has been fully deployed and the limiting column 304 is stuck to the limit. At the outermost side of the chute 601 , when the positioning structure 8 loses its extrusion and moves outward, the positioning post 803 will be stuck into the positioning hole in the middle of the limiting post 304 , thereby fixing the connecting rod 303 .

beneficial effects.

The usage process of a photovoltaic centralized inverter power generation system and device provided by the invention is as follows:

Pull the heat dissipation structure 3 and the support structure 5 outward by pulling the handle 4. At this time, the seat plate 301 on the top of the heat dissipation structure 3 will move outward simultaneously, and the connecting rod 303 will slide open inside the limiting chute 601. When the overlapping limit rod 206 on the top of the seat plate 301 enters the relief groove 305, the limit rod 206 will automatically descend. At this time, the side plate 2 will lose its restriction, and the side plate 2 will automatically rotate under the action of the torsion spring. The outside is opened, thereby exposing the electrical components 203 inside the side panel 2 to the outside world, making it convenient for the staff to inspect and repair. When the heat dissipation structure 3 is completely pulled out, the pressure block 502 inside the support structure 5 is restricted by the gear rod 506, so that the The pressing block 502 presses the convex block 505 downward, so that the supporting leg 503 moves downward from the inside of the supporting structure 5 to support the ground, so that the supporting structure 5 can support the outer end of the heat dissipation structure 3. The connecting rod 303 supports the inner end of the seat plate 301 to ensure the stability of the heat dissipation structure 3. When the heat dissipation structure 3 is completely pulled out, the side plate 2 drives the driving gear 701 to rotate, thereby causing the transmission gear to rotate. 702 The traction cam 704 rotates, so that the positioning structure 8 is supported by the support spring 801, and the top of the limiting column 304 is limited and clamped through the positioning column 803, thereby ensuring the stability of the heat dissipation structure 3;

When the heat dissipation structure 3 is retracted, by pressing the ejector pin 802, the ejector pin 802 will squeeze the entire positioning structure 8 inward. At this time, the positioning column 803 will be separated from the middle positioning hole of the limiting column 304. At this time, the positioning will be limited. The column 304 loses its restriction, so that the heat dissipation structure 3 can move, thereby facilitating the storage of the heat dissipation structure 3. At the same time, the support structure 5 moves inward, and the inner end of the pressure block 502 is blocked by the support plate 501, so that the pressure block 502 moves from the protrusion The top of the block 505 is detached, and the support legs 503 are retracted into the support structure 5 for storage under the support of the return spring 504. When the heat dissipation structure 3 is completely retracted, the baffle 302 in the middle of the heat dissipation structure 3 is tilted. Under the support of the rod 308, it will open to the outside, and the support frame 307 will be propped up by the air bag 306, thereby supporting the warping rod 308 and ensuring that the baffle 302 is opened. In cold weather and windy and rainy days, the baffle 302 will be in the wind. It will close when it is blown to prevent rainwater from entering. At the same time, the helium gas in the cold weather bag 306 shrinks when it is cold. At this time, the baffle 302 loses support and will also close the heat dissipation structure 3 and the heat dissipation port, thereby protecting the equipment. effect.
