It organically combines the functions of transformer step-down and low-voltage distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box. In order to avoid serious heat accumulation inside the box-type substation and cause damage to the equipment, cooling equipment is installed on the box-type substation. The cold air outside the box is sucked in by the fan, and then enters the box through the protective plate, so that air flows inside the box, thereby achieving cooling.

[0003] Existing patent: CN210092667U, discloses a box-type substation, which can ensure the heat dissipation effect in the transformer box when the weather is hot, so that the transformer box maintains a suitable temperature, thereby improving the service life of the transformer device, including a transformer box, two groups of cooling fans and a transformer device, a transformer cavity is arranged inside the transformer box, a transformer port is arranged on the front side of the transformer box, a cover plate is arranged inside the transformer port, two groups of heat dissipation ports are respectively arranged on the left and right sides of the transformer box, two groups of cooling fans are respectively installed in the two groups of heat dissipation ports, the transformer device is installed inside the transformer box, and also includes a support plate, a storage box, a cooling pump, a heat exchanger and a heat exchange plate, the support plate is fixed to the bottom inside the transformer box, the left front side, the right front side, the left rear side and the right rear side of the support plate are respectively connected to the left front side, the right front side, the left rear side and the right rear side of the inner wall of the transformer box, and there is a certain gap between the support plate and the bottom of the transformer box.

[0004] The above patent or existing box-type substation cooling equipment has the following problems:

[0005] The protective plate of the existing cooling equipment is used to prevent animals such as insects and mice from entering the box body, and it also plays a role in reducing the dust from entering the inside of the box body. Therefore, the aperture of the protective plate is relatively small.

DETAILED DESCRIPTION

[0022] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0023] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a cooling device for a box-type substation, including a box plate 1, which is a plate of a box-type substation. The box plate 1 is equipped with a protective plate 2 for preventing mosquitoes, mice and other animals or dust from entering when a fan 3 absorbs external air. The fan 3 is installed on the surface of the box plate 1, and the position of the fan 3 corresponds to the protective plate 2. A protective plate disassembly assembly component 4 is provided on the box plate 1, and the protective plate 2 is connected to the protective plate disassembly assembly component 4.

[0024] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a cooling device for a box-type substation. The protective plate disassembly assembly 4 includes a mounting box 41, which is fixed to the rear surface of the box plate 1 by bolts. A pressing block 42 is arranged at the middle end of the inner part of the mounting box 41. The pressing block 42 protrudes from the top of the mounting box 41, and the pressing block 42 is vertically connected to the top of the mounting box 41 by sliding up and down. The pressing block 42 is integrally formed on the top surface of the push block 43. A pressing rebounder 44 is assembled at the middle lower end of the mounting box 41, and the push block 43 is connected to the pressing rebounder 44.

[0025] Slide plates 45 are installed at both left and right ends of the installation box 41. The structures of the slide plates 45 at both ends are the same and symmetrical, and the slide plates 45 are in contact with the surface of the push block 43. At the same time, the surfaces of the slide plates 45 and the push block 43 in contact are inclined. The slide plates 45 slide along the surface of the fixed plate 46 fixed inside the installation box 41. A spring 47 is installed between the fixed plate 46 and the slide plates 45. One end of the spring 47 is fixed to the surface of the fixed plate 46, and the other end is fixed to the surface of the slide plates 45. A cross bar 451 is integrally formed in the middle of the slide plates 45. The cross bar 451 runs through the middle of the fixed plate 46, and the cross bar 451 will follow the slide plates 45. The slide plate 45 is moved and slides along the inner wall of the fixed plate 46. The cross bar 451 can effectively prevent the spring 47 from bending, and at the same time, the slide plate 45 is not easy to warp, so that the slide plate 45 can maintain parallel sliding. A positioning rod 452 is fixed to the inner side of the installation box 41 by bolts. The positioning rod 452 penetrates into the interior of the slide plate 45, and the slide plate 45 slides along the surface of the positioning rod 452 when sliding, effectively preventing the end of the slide plate 45 from shaking. The lower end of the slide plate 45 is integrally formed with a limiting plate 48, and the surface of the protective plate 2 is provided with an inserting plate 49. When the inserting plate 49 is inserted into the interior of the installation box 41, it can be limited by inserting the limiting plate 48 therein;

[0026] The push block 43 is internally equipped with a roller 431, which contacts the inclined surface of the slide plate 45, so that the slide plate 45 is affected by the spring 47 to better push the push block 43 to slide, while reducing friction, so that the push block 43 slides downward to better push the slide plate 45 to slide;

[0027] When it is necessary to dismantle the protective plate 2 for cleaning, the staff presses the pressing block 42 downwards to push the pushing block 43. At this time, the pushing block 43 pushes the pressing rebounder 44. After the pressing rebounder 44 is pressed by force, the limit of the pushing block 43 is released. Then the spring 47 pushes the slide plate 45 to slide. At the same time, the slide plate 45 pushes the pushing block 43 to slide upwards, and also drives the limiting plate 48 to slide out of the plug plate 49, thereby releasing the limit of the plug plate 49. Then the staff can remove the protective plate 2 for disassembly and cleaning. When installing, it is only necessary to dock the protective plate 2 on the box plate 1. Then the plug plate 49 will be inserted into the installation box 41, and then the pressure block 42 will be pressed to push the push block 43, and the push block 43 will slide downward to push the slide plate 45, so that the limit plate 48 is inserted into the plug plate 49, and then the push block 43 is fixed by pressing the rebounder 44, thereby completing the limitation of the plug plate 49 to achieve the installation and fixation of the protective plate 2, so as to achieve convenient disassembly or installation of the protective plate 2, so that it is convenient to maintain when the protective plate 2 is blocked and affects the cooling effect, and at the same time, after removing the protective plate 2, the inside of the fan 3 can also be maintained, which improves convenience.
