Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 4, a box-type substation includes an outer box and several groups of function cabinets 8 placed in the outer box. The function cabinets 8 include high and low voltage power distribution rooms, capacitor rooms and transformer rooms. The structure is determined according to the needs of the substation, and the conventional design is adopted, which will not be repeated here.

The outer box includes a top cover 1, a box body 2, and a base 5 that are connected in sequence from top to bottom. The box body 2 is provided with several separate chambers. The four sides of the top cover 1 and the base 5 are opposite to the four sides of the box body 2. Extending outward, the upper and lower areas of the box body 2 are smaller than the corresponding top cover 1 and base 5 , so that the box body 2 is placed in the protection of the two, and the functional cabinet 8 is placed in the cabinet inside the box body 2 .

In order to facilitate the function cabinet 8 to be loaded into and removed from the chamber of the box body 2, a bracket 7 is installed at the bottom of each chamber, and the bracket 7 is connected to the bottom of the chamber through several sets of sliding assemblies 6. The sliding assemblies 6 include fixedly installed in the chamber The fixed rail at the bottom and the moving rail fixedly installed at the bottom of the bracket 7, the fixed rail and the moving rail match each other. In the specific implementation, the function cabinet 8 is placed in the bracket 7, and the moving rail drives the bracket 7 to move along the fixed rail inside and outside. , so that the function cabinet 8 can be loaded and removed quickly, conveniently and efficiently. Since the weight of the functional cabinets 8 is not small, in order to improve the service life of the brackets 7, several groups of support rods 4 are also arranged at the bottom of each cabinet. The support rods 4 are located between the two sliding assemblies 6. Shelf 7 is offset. The sliding assembly 6 is electrically controlled, and is also equipped with a self-locking structure, all of which are of conventional design, and will not be repeated here.

In order to make the process from the function cabinet 8 to the bracket 7 more convenient, the bracket 7 includes a frame 701 and a pedal 702 on the outside of the frame 701 through hinged installation. Enclosing a frame with an opening on the outside, two sets of side plates 701b extend outward relative to the bottom plate 701a to form a cavity, both ends of the pedal 702 are hinged with the extension of the two sets of side plates 701b, and there are also tightening clamps on the pedal 702 and the side plates 701b. The fastening connection member includes the connection hole 703 on the side plate 701b and the plug 704 installed on the pedal 702 that matches the connection hole 703. When the pedal 702 is closed, the plug 704 is inserted into the connection hole 703, so that the pedal 702 is tightly connected with the side plate 701b, as shown in Figure 4(b); when the pedal 702 needs to be unfolded, pull out the plug 704 from the connection hole 703, and release the two to complete the separation of the pedal 702 from the side plate 701b, as shown in Figure 4 (a).

When the functional cabinet 8 needs to be moved in from the bracket 7, the pedal 702 is unfolded, and the pedal 702 forms a bridge between the ground and the inside of the frame 701, which can reduce the difficulty of operation. The functional cabinet 8 is pushed into the frame 701 through the pedal 702, and then The pedal 702 is closed, so that the frame 701 is sealed around, and finally the moving rail is slid to move the bracket 7 into the chamber. In the process of removing the function cabinet 8, the above steps can be reversed.

The top cover 1 includes a top beam 101 in the middle, a peripheral eaves 103, and a cover plate 102 between the top beam 101 and the peripheral eaves 103. The cover plate 102 slopes downward from the top beam 101 to the peripheral eaves 103 to facilitate rainwater drainage. The outer peripheral eaves 103 and the cover plate 102 form a concave surrounding groove 105. Since the box body 2 is mostly a cube, the top cover 1 is also a rectangle when viewed from the top, and the surrounding groove 105 is a frame-shaped groove. The four corners of the surrounding groove 105 are provided The drain port 104, the end of the drain port 104 is connected to the drain pipe 3, the top of the drain pipe 3 is connected to the drain port 104, the end is connected to the outside through the base 5, and the end of the drain pipe 3 is a water outlet. It falls into the enclosing groove 105 along the cover plate 102 , and is then discharged out through the drain port 104 and the drain pipe 3 , so that the rainwater will not fall on the base 5 and splash into the box 2 . In the specific implementation, the roof beam 101 , the cover plate 102 , the outer peripheral eaves 103 , and the surrounding groove 105 are integrated into one structure.

In a preferred structure, the cover plate 102 is a corrugated plate, which has a stable structure, strong compressive performance and makes the rainwater more fluid.

In order to facilitate drainage, the bottom surface of the surrounding ditch 105 slopes downward toward the drainage opening 104 . For example, the height of the bottom surface of the surrounding ditch 105 between the two drainage openings 104 is gradually reduced from the middle to the two drainage openings 104 , so that a surface facing the drainage opening 104 is formed. The inclined uneven surface is convenient to accelerate the flow of the water body to the water outlet 104 and avoid water accumulation.

The upper parts of the four corners of the outer peripheral eaves 103 are provided with overflow ports 106 to prevent excess water from being discharged from the ditch 105 from the overflow port 106 when the rainwater is too large.

The above descriptions only represent the preferred embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as limiting the scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications, improvements and substitutions can be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for this utility model shall be subject to the appended claims.
