Description
Technical Field
[0001] This utility model is a waterproof structure for the top of a cabinet, belonging to the field of power distribution cabinet technology. Background Technology
[0002] Waterproofing the top of the distribution cabinet is crucial to prevent rainwater, moisture, or other water sources from entering the cabinet, thus avoiding damage to electrical equipment or safety accidents. Installing a rain cap on the top of the distribution cabinet is a common waterproofing measure. To facilitate lifting the cabinet, at least four lifting lugs need to be welded to the top of the rain cap. To improve lifting safety, the rain cap needs to be sufficiently thick. However, using a thicker rain cap increases production costs. Therefore, it is necessary to design a waterproof structure for the top of the cabinet that minimizes the thickness of the rain cap while ensuring lifting safety. Summary of the Invention
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof structure for the top of the box to solve the problems mentioned in the background. This utility model reduces the thickness of the rain cap as much as possible while ensuring lifting safety, thereby reducing production costs.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for the top of a box, comprising a box body, a rain cap with a gap between the top of the box body and the top of the box body, the four sides of the rain cap extending below the top of the box body, and multiple evenly arranged louvered ventilation holes processed on the four sides of the rain cap, a fan mounting port opening at the center of the top of the box body, a baffle on the outer side of the fan mounting port, the baffle being installed on the top of the box body, four connecting rods evenly installed on the top of the box body, the upper ends of the connecting rods being connected and fixed to the rain cap, two connecting plates on the upper side of the rain cap, two lifting lugs installed on the upper surface of the connecting plates, L-shaped plates installed on the opposite sides of the two connecting plates, the lower ends of the vertical parts of the L-shaped plates extending to the lower part of the side of the box body, a support plate at the bottom of the box body, two supports symmetrically installed on the lower surface of the support plate, and the vertical parts of the L-shaped plates being connected to the supports by multiple connecting bolts.
[0005] Furthermore, a cabinet door is hinged to one side of the cabinet body, and an operation opening is provided at the upper part of the front of the cabinet door. A U-shaped cover is provided on the upper side of the operation opening, and the U-shaped cover is connected to the cabinet door. A transparent door panel for sealing the operation opening is hinged to one edge of the operation opening, and a limiting member for restricting the position of the cabinet door and the transparent door panel is installed on the vertical part of the L-shaped panel.
[0006] Furthermore, the limiting component includes a screw rod, and a detachable screw rod is installed on the vertical part of the L-shaped plate. The screw rod is arranged vertically. A limiting plate is provided on the side of the cabinet door away from the cabinet body. The limiting plate has an L-shaped structure. A vertical hole is opened on the side of the limiting plate near the screw rod. The screw rod passes through the vertical hole. Nuts that are threadedly connected to the screw rod are provided on the upper and lower sides of the vertical hole. Multiple screw holes are evenly opened on the side of the limiting plate facing the cabinet door. A clamping screw is threaded into the screw hole. The end of the limiting plate with the vertical hole slides in contact with the vertical part of the L-shaped plate.
[0007] Furthermore, both ends of the screw are equipped with lugs, which are connected to the L-shaped plate by screws.
[0008] Furthermore, a reinforcing plate is provided between the two connecting plates, and a first connecting ear is fixedly connected to both ends of the reinforcing plate. A second connecting ear that fits into the first connecting ear is installed at the middle position of the upper surface of the connecting plate, and the first connecting ear is connected to the second connecting ear by bolts.
[0009] Furthermore, the four sides of the rain cap are all bent inward to form a bottom edge that contacts the side of the box, and a strip-shaped ventilation opening is provided on the lower surface of the bottom edge.
[0010] The beneficial effects of this utility model are:
[0011] 1. Extend the four sides of the rain cap to below the top of the box, and bend all four sides of the rain cap inward to contact the side of the box. Then, set a baffle on the outside of the fan installation port. With the rain cap and the baffle working together, rainwater is prevented from entering the box through the fan installation port.
[0012] 2. L-shaped plates are installed on both sides of the container, and a structure formed by a support plate and a bracket is placed at the bottom of the container. The L-shaped plates are then connected to the brackets using connecting screws. At this time, the connecting plate with the lifting lugs is on the upper side of the rain cap, completing the assembly of the lifting lugs and the rain cap. When the container is started, the structure formed by the brackets, support plates, L-shaped plates, connecting plates, and lifting lugs bears the force, so that the rain cap is not stressed. This achieves the goal of minimizing the thickness of the rain cap while ensuring lifting safety and reducing production costs. After the container is hoisted, the support plates, connecting plates, etc. are separated for easy recycling and reuse.
[0013] 3. Install a reinforcing plate between the two connecting plates to improve the stability of their relative positions.
[0014] 4. Adjust the position of the limiting plate along the screw according to the height of the transparent door panel, so that the limiting plate is opposite to the transparent door panel. Then use two nuts to restrict the relative position of the limiting plate and the screw, so as to facilitate the adjustment of the position of the limiting plate. Tighten the clamping screws into some of the screw holes so that the clamping screws are in contact with the transparent door panel. Thus, the limiting plate, clamping screws and other components work together to restrict the position of the transparent door panel and cabinet door, preventing the transparent door panel or cabinet door from opening at will during the lifting process.
