[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0022] The present application provides a box-type substation door sealing structure, which is mainly used to solve the problem that after the door of some box-type substations is closed, the sealing performance between the box door and the box body is poor, which easily causes dust and other impurities to enter the inner side of the substation through the gap between the door panel and the substation, affecting the normal operation of the equipment in the substation and affecting the service life of the equipment, and provides the following technical solutions, which will be combined with Figure 1-Figure 4 Make a detailed description:

[0023] A box-type substation door sealing structure mainly includes a box body 1 and a box door 2. One side of the box door 2 is hinged to the box body 1. A mounting frame 3 is fixed on the inner wall of the box body 1. The mounting frame 3 is close to the opening of the box body 1. A sealing sleeve 4 that is the same as the mounting frame 3 is installed on the side of the mounting frame 3 close to the opening of the box body 1. It should be noted that the sealing sleeve 4 is made of rubber material. When the box door 2 is closed, one side of the sealing sleeve 4 fits with one side of the box door 2 to achieve a sealing effect and prevent dust and impurities from entering. A accommodating groove 41 is constructed on the side of the sealing sleeve 4 close to the mounting frame 3. A plurality of evenly distributed springs 42 are connected between the mounting frame 3 and the inner wall of the sealing sleeve 4. Under the elastic force of the plurality of springs 42, one side of the sealing sleeve 4 can be tightly fitted with the box door 2, so that the sealing is higher, the sealing performance is improved, and the sealing structure has a certain elasticity, which can adapt to the deformation of the box body 1 and the influence of environmental factors, and maintain the stability of the sealing performance. The box door 2 and the box body 1 are fixed by a fixing buckle 5.

[0024] In this example, see Figure 3 and Figure 4 A fitting plate 43 is fixed to one end of the spring 42, and one side of the fitting plate 43 fits with the inner wall of the sealing sleeve 4. The arrangement of several fitting plates 43 can make one side of the sealing sleeve 4 smoother, so that one side of the sealing sleeve 4 fits better with the box door 2, and the sealing performance is higher.

[0025] For further information, see Figure 1 and Figure 3 A sealing gasket 21 identical to the mounting frame 3 is fixed to one side of the box door 2. The sealing gasket 21 corresponds to the sealing sleeve 4. The sealing gasket 21 is made of rubber and has a certain deformation ability. It can better fit with one side of the sealing sleeve 4, and the dust and moisture proof effect is better.

[0026] For details, please refer to Figure 3 The longitudinal section of the box door 2 is larger than the longitudinal section of the opening of the box body 1. The sealing gasket 21 is movably inserted in the opening of the box body 1 and the outer side wall of the sealing gasket 21 fits with the inner side wall of the box body 1. When the box door 2 is closed, the sealing gasket 21 fits with the sealing sleeve 4, and the outer side wall of the sealing gasket 21 fits with the inner side wall of the box body 1 to form a complete sealing structure. This sealing gasket 21 can fill the gap between the box door 2 and the box body 1 and improve the sealing performance.

[0027] For further information, see Figure 1 A number of evenly distributed magnets 11 are embedded on the opening side of the box body 1, and an iron sheet 22 corresponding to the number of magnets 11 is embedded on one side of the box door 2. When the box door 2 is closed, the magnets 11 and the iron sheet 22 attract each other, thereby enhancing the fit between the box door 2 and the box body 1, further improving the sealing performance, and preventing the fixing buckle 5 from loosening while still ensuring the sealing performance.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
