Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically a photovoltaic grid-connected switchgear with a protective structure. Background Technology

[0002] In the field of photovoltaic grid-connected switchgear technology, switchgear plays a crucial role in the stable operation of power systems. Its internal wiring is complex and precise, requiring proper protection.

[0003] A search of Chinese Patent Publication No. CN221978438U reveals a centrally located switchgear with a protective structure. This switchgear includes a cabinet body and multiple equally spaced slots near the bottom of its rear side. Fixed protective plates are installed below these slots, and movable protective plates slide above them. This invention utilizes the arc-shaped rubber blocks of the fixed protective plates to protect the bottom of the cables. The movable protective plates descend, and a rotating screw lowers the arc-shaped silicone blocks to clamp and surround the top of the cables. This accommodates cables of different diameters and seals the slots to prevent rodents from entering. Simultaneously, fumigation pills in the fumigation cylinder release odors that deter rodents and snakes from approaching the slots, improving the protective effect and effectively preventing dust and rodents from entering the cabinet through the slots and damaging the internal wiring.

[0004] However, its structure still has shortcomings. For example, it uses a combination of fixed and movable protective plates to fix cables and seal slots for rodent prevention. This method cannot be adapted to different cable sizes, but in actual use, the switchgear needs to connect multiple devices, resulting in varying cable sizes. Therefore, the above structure cannot meet the requirements. Furthermore, in terms of insect control, it uses fumigation pills in an external fumigation cylinder to repel rodents and snakes, which can easily lead to the fumigation pills evaporating too quickly and being ineffective, significantly reducing the protective effect. Therefore, we propose a photovoltaic grid-connected switchgear with a protective structure. Utility Model Content

[0007] Preferably, the adjusting mechanism includes a slide rod, a top ring, a connecting hole, and a spring, the top ring is threadedly connected to the mounting block, the top ring is a circular ring structure, and the outer diameter of the top ring gradually decreases away from the switch cabinet body, one end of the top ring close to the L-shaped linkage piece is located between the L-shaped linkage piece and the mounting block, four slide rods are fixedly connected to the outer wall surface of the mounting block corresponding to the four L-shaped linkage pieces, connecting holes are formed in the L-shaped linkage pieces corresponding to the positions of the slide rods, the slide rods extend to the outside of the L-shaped linkage pieces through the connecting holes, springs are sleeved on the slide rods, and the springs are located outside the L-shaped linkage pieces.

[0008] Preferably, the top ring is fixedly connected to the side wall surface close to the switch cabinet body, the outer wall surface of the auxiliary ring has a roughness of 300 mesh, and the side wall surface of the mounting block away from the switch cabinet body is fixedly connected with a sliding block corresponding to the positions of the four L-shaped linkage pieces.

[0009] Preferably, the four fixed baffles are each in the form of a sector, and the four fixed baffles are connected together in a circular ring structure.

[0010] Preferably, the outer wall surface of the mounting block is provided with a connecting groove at one end close to the switch cabinet body, a placing groove is formed in the side wall surface of the connecting groove away from the switch cabinet body, the insecticide package is movably connected in the placing groove, a plurality of exhausts are formed in the inner wall surface of the placing groove, and the exhausts communicate with the inside of the mounting block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By incorporating an adjustable fixing baffle and its corresponding adjustment mechanism (including a slide bar, top ring, connecting hole, and spring), the system effectively accommodates and secures cables of various sizes. This structure allows for the opening, closing, and clamping of the fixing baffle by rotating the top ring, based on the actual cable thickness. This ensures smooth installation of cables of different specifications while preventing rodents from entering the switch cabinet and damaging the wiring. This significantly improves the equipment's compatibility and practicality with different cables, reduces usage limitations caused by cable size differences, and effectively guarantees the safe and stable operation of the switch cabinet's internal wiring.

[0014] 2. By incorporating an insect repellent packet, placement slot, vent, and sealing ring within the mounting block, highly efficient insect repellency and an extended lifespan of the repellent packet are achieved. The insect repellent packet, placed in the placement slot, releases its odor through the vent into the mounting block and switch cabinet, effectively repelling insects. The sealing ring, along with the limiting ring and limiting slot, facilitates the replacement of the insect repellent packet. Simultaneously, the mounting block prevents the odor from dissipating too quickly, ensuring the packet's continuous and stable effectiveness. This reduces the manpower and material costs associated with frequent packet replacements, further enhancing the switch cabinet's protective performance and lowering the risk of insect damage to internal wiring.

[0015] 3. By setting an auxiliary ring on the top ring with an outer surface roughness of 300 mesh, the adjustment mechanism is made easier for operators to operate. The rough surface of the auxiliary ring increases the frictional resistance with the operator's hand, allowing for easier and more precise force application when rotating the top ring to control the opening and closing of the fixed baffle. This improves the convenience and efficiency of operation, reduces the difficulty of operation, and significantly saves time and effort, especially during repeated cable installation or maintenance, thus enhancing the user experience during equipment use and maintenance.

[0016] 4. By setting sliding rods, sliders, connecting holes, and sliding grooves to limit the movement of the L-shaped linkage block, the stable operation of the equipment adjustment mechanism is ensured. During the adjustment of the fixed baffle position, these limiting structures ensure that the L-shaped linkage block can only move in a specific direction, avoiding displacement deviations caused by external interference or component wear. This makes the opening and closing action of the fixed baffle more accurate and reliable, thereby ensuring the normal operation of the entire protective structure, reducing the probability of equipment failure caused by component misalignment, improving the stability and durability of equipment operation, and reducing maintenance costs and downtime.
