DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution: a waterproof top plate of a high-voltage switch cabinet, comprising a switch cabinet 1, having a cabinet body 1-1 and a cabinet door 1-2; a fixed top plate 2 is arranged on the top of the switch cabinet 1; an inclined top plate 3 is arranged on the fixed top plate 2 and is located above the cabinet door 1-2; the upper end of a C-shaped baffle 4 is rotatably mounted on the bottom of the inclined top plate 3, and its lower end can be movably connected with the cabinet body 1-1 by snapping; a limiting structure 5 is arranged on the inclined top plate 3, and is used to limit the C-shaped baffle 4. In rainy weather, the top of the high-voltage switch cabinet is rainproofed by the fixed top plate 2 and the inclined top 3. The C-shaped baffle 4 is used to block the door gap between the cabinet door 1-2 and the cabinet body 1-1, preventing rainwater from easily entering the cabinet body 1-1 through the door gap formed between the cabinet body 1-1 and the cabinet door 1-2. The components inside the cabinet body 1-1 are prone to leakage due to water. When maintenance personnel repair the high-voltage switch cabinet on rainy days, they can rotate the C-shaped baffle 4 and limit it through the limiting structure 5. The maintenance personnel can block the rain through the C-shaped baffle 4, avoiding rainwater from easily entering the interior of the high-voltage switch cabinet when the cabinet door 1-2 is opened, which is convenient for maintenance personnel to repair the device on rainy days.

[0026] Specifically, the limiting structure 5 includes a fixed block 5-1 arranged at the bottom of the inclined top plate 3 and located on the outside of the C-shaped baffle 4, a first groove 5-2 is provided on the side where the two fixed blocks 5-1 are close to each other, the groove bottom spring of the first groove 5-2 is connected to the connecting block 5-3, the side wall of the connecting block 5-3 is provided with a limiting block 5-4 with a triangular cross-section, the side wall of the C-shaped baffle 4 is provided with a limiting groove 5-5 adapted to the limiting block 5-4, an L-shaped opening 5-6 is provided on the side wall of the fixed block 5-1, and a hand handle 5-7 extending out of the L-shaped opening 5-6 is provided on the side wall of the connecting block 5-3, and the L-shaped opening 5-6 includes a long side portion for the hand handle 5-7 to slide and a side portion for limiting the hand handle 5-7 When the C-shaped baffle 4 is used for rain protection, the C-shaped baffle is pulled upward to contact the inclined surface of the limit block 5-4, and the limit block 5-4 drives the connecting block 5-3 to move into the first groove 5-2, and the spring is compressed. When it moves to the limit groove 5-5, the compressed spring drives the connecting block 5-3 and the limit block 5-4 to move, so that the limit block 5-4 is connected to the limit groove 5-5 to achieve limitation. After use, the maintenance personnel pushes the handheld handle 5-7 to drive the connecting block 5-3 and the limit block 5-4 to move, and move to the short side of the L-shaped channel 5-6 to cancel the limitation. The limit structure 5 is set to achieve the limitation of the opened C-shaped baffle 4.

[0027] Specifically, a rubber stopper 9 matched with the C-shaped baffle 4 is provided at the bottom of the inclined top plate 3. By providing the rubber stopper 9, the C-shaped baffle 4 contacts the rubber stopper 9 after opening, thereby effectively preventing splashing rainwater from entering the interior of the cabinet 1-1 through the gap between the inclined top plate 3 and the C-shaped baffle 4, thereby preventing the components in the cabinet 1-1 from leaking due to splashing rainwater.

[0028] Specifically, an annular rubber stopper 10 is provided on the C-shaped baffle 4 close to the side wall of the cabinet 1-1 and located on the outer side of the cabinet door 1-2. The annular rubber stopper 10 can effectively prevent humid air from entering the cabinet 1-1 through the door gap between the cabinet 1-1 and the cabinet door 1-2 on rainy days, thereby preventing the components in the cabinet 1-1 from leaking due to the humid air.

[0029] Specifically, a second groove 6 is provided on the side wall of the cabinet 1-1, and the bottom spring of the second groove 6 is connected to an arc-shaped clamping block 7. A V-shaped clamping groove 8 is provided on the inner wall of the C-shaped baffle 4. The arc-shaped clamping block 7 on the cabinet 1-1 is movably clamped with the V-shaped clamping groove 8 to ensure the stability of the annular rubber block 10 and the cabinet 1-2.

[0030] Specifically, a handle 11 is provided on the side wall of the C-shaped baffle 4 away from the cabinet 1 - 1 . The handle 11 is provided to facilitate maintenance personnel to hold the handle 11 to drive the C-shaped baffle 4 to rotate.

[0031] Working principle: When the utility model is working, in rainy weather, the fixed top 2 and the inclined top plate 3 protect the top of the high-voltage switch cabinet from rain, and the C-shaped baffle 4 is movably connected to the cabinet body 1-2 to block the door gap between the cabinet door 1-2 and the cabinet body 1-1. During maintenance, the C-shaped baffle 4 is rotated to open and limited by the limiting structure 5. The maintenance personnel use the C-shaped baffle 4 to block rainwater, thereby preventing rainwater from entering the interior of the high-voltage switch cabinet.
