Spring slide rods are arranged on both the upper and lower sides of the buffer frame, and support rods are slidably installed on the surfaces of the spring slide rods. One end of the support rod away from the spring slide rod is connected to an energy absorption plate, and damping buffer columns are symmetrically installed at both the upper and lower ends of the energy absorption plate.

The utility model, through the use of the filter, when the compressor fan is in operation, when the external air is drawn in by the air inlet pipe, the impurities in the gas can be effectively filtered, so as to avoid adverse effects on the transformer unit installed inside the entire substation box group.

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] like Figures 1 to 5As shown, a heat dissipation and ventilation component and a prefabricated cabin substation include a substation box group 1 and an air intake component 6, a protective frame group 2 is symmetrically installed on the left and right sides of the substation box group 1, and an explosion-proof door 3 is installed on the front and side facades of the substation box group 1, and a top frame component 4 is symmetrically installed on the top of the substation box group 1, and a transformer unit 5 is installed inside the substation box group 1, the air intake component 6 is installed at the top center of the substation box group 1, and the exhaust component 7 is symmetrically arranged on the left and right sides of the air intake component 6, the air intake component 6 includes a filter 601, an air inlet pipe 602, a compression fan 603 and a movable air duct 604, the air inlet pipe 602 is symmetrically installed on the top of the filter 601, and the bottom of the filter 601 is connected to the compression fan 603, and the bottom of the compression fan 603 is symmetrically installed with an movable air duct 604, the exhaust component 7 includes a centrifugal fan 701, a fixing frame 702, a purification box 703 and an exhaust port 704. A fixing frame 702 is installed on one side of the centrifugal fan 701 close to the inner wall of the transformer substation box group 1, and a purification box 703 is connected above the centrifugal fan 701, and an exhaust port 704 is provided on the purification box 703. Through the use of the filter 601, when the compression fan 603 is in operation, when the external air is drawn in through the air inlet pipe 602, the impurities in the gas can be effectively filtered. At the same time, under the operation of the compression fan 603, the air transported in from the outside will be compressed and cooled, and blown to the interior of the entire transformer substation box group 1 with the transmission of the movable air duct 604, so as to provide heat dissipation and cooling for the transformer unit 5. In addition, under the operation of the centrifugal fan 701, part of the heat generated by the transformer unit 5 will be cooled with the operation of the compression fan 603, and the other part will be extracted by the centrifugal fan 701, and filtered by the purification box 703 and transported to the outside through the exhaust port 704, thereby reducing the impact on the outside.

[0025] The substation box group 1 includes an electromagnetic sound insulation chamber 101, a display light strip 102, a collision prevention frame 103, a warning light 104 and a platform 105. The display light strips 102 are symmetrically installed on the left and right sides of the outside of the electromagnetic sound insulation chamber 101, and the collision prevention frames 103 are installed on both the upper and lower sides of the outside of the electromagnetic sound insulation chamber 101. Moreover, the warning lights 104 are installed on both the left and right sides of the top collision prevention frame 103 of the electromagnetic sound insulation chamber 101, and the platform 105 is installed on the side of the bottom collision prevention frame 103 of the electromagnetic sound insulation chamber 101 close to the ground. The collision prevention frame 103 is arranged in a "U" - shaped structure. The display light strip 102 is vertically installed on the side of the electromagnetic sound insulation chamber 101. The protection frame group 2 includes a buffer frame 201, a spring slide rod 202, a support rod 203, an energy absorption plate 204 and a damping buffer column 205. The spring slide rods 202 are arranged on both the upper and lower sides of the buffer frame 201, and the support rod 203 is slidably installed on the surface of the spring slide rod 202. Moreover, one end of the support rod 203 far from the spring slide rod 202 is connected to the energy absorption plate 204, and the damping buffer columns 205 are symmetrically installed at both the upper and lower ends of the energy absorption plate 204. The energy absorption plate 204 is parallel to the buffer frame 201, and the damping buffer columns 205 are horizontally installed between the buffer frame 201 and the energy absorption plate 204. The top frame assembly 4 includes a top plate 401, a telescopic column 402 and a support rotating shaft 403. The telescopic column 402 is installed on one side of the bottom of the top plate 401 close to the vertical central axis of the substation box group 1, and the support rotating shaft 403 is installed at one end of the bottom of the top plate 401 far from the telescopic column 402. By arranging the collision prevention frames 103 on both the upper and lower sides of the electromagnetic sound insulation chamber 101, the corners of the electromagnetic sound insulation chamber 101 can be prevented from being damaged due to collision. The use of the display light strip 102 and the warning light 104 can provide an effective position hint for the whole device at night. When the energy absorption plate 204 receives an external force, it will simultaneously push and compress the damping buffer columns 205 at both the upper and lower ends and the middle - section connecting support rod 203. The support rod 203 will be structurally extruded along the surface of the spring slide rod 202 on the buffer frame 201. By using the structural elastic expansion and contraction of the spring slide rod 202 and the damping buffer column 205, the buffer protection can be achieved. In addition, with the structural expansion, contraction and support adjustment of the telescopic column 402 and the support rotating shaft 403, the inclination angle of the top plate 401 can be adjusted within a certain range, so as to play a role in hydrophobic shielding for the top of the electromagnetic sound insulation chamber 101 in rainy weather.

[0026] In summary, as Figures 1 to 5As shown, when the heat dissipation and ventilation components and the prefabricated cabin transformer substation are used, first, after the entire equipment is set at the designated position, the operating personnel can enter and exit through the explosion-proof door 3 set on the front and side facades of the transformer substation box group 1, so as to facilitate the maintenance and inspection of the internal equipment. When the transformer unit 5 inside the electromagnetic soundproof cabin 101 is in operation, the air intake component 6 and the exhaust component 7 will also operate synchronously. After the compression fan 603 is started, the external air is drawn in with the assistance of the air inlet pipe 602. After the external air is purified by the filter 601, it is compressed and refrigerated by the compression fan 603, and then continuously transported to the interior of the electromagnetic soundproof cabin 101 by the movable air duct 604, thereby providing a cooling effect for the transformer unit 5;

[0027] In this process, the centrifugal fan 701 installed on the upper end of the inner wall of the electromagnetic soundproof chamber 101 by the fixing frame 702 will transport the air inside the electromagnetic soundproof chamber 101 to the inside of the purification box 703, and then be discharged to the outside from the exhaust port 704 after being filtered in the purification box 703, thereby forming a circulation operation for heat dissipation and ventilation inside the entire substation box group 1;

[0028] When the whole device is operated at night, the display light strips 102 on the left and right sides of the electromagnetic soundproof chamber 101 and the warning light 104 will provide effective night warning lighting to prevent vehicles from colliding with it, and the platform 105 will lift the whole substation box group 1 from the ground structure to prevent rainwater from invading the interior of the electromagnetic soundproof chamber 101 in rainy weather as much as possible, thereby damaging the transformer unit 5;

[0029] If the side of the substation box group 1 is subjected to external force, the energy absorbing plate 204 will first resist and absorb the force, and at the same time, the damping buffer columns 205 at the upper and lower ends and the middle connecting support rod 203 will be structurally pushed and compressed. The support rod 203 will be structurally squeezed along the surface of the spring slide bar 202 on the buffer frame 201, and the structural elasticity of the spring slide bar 202 and the damping buffer column 205 is utilized to achieve buffering protection. When falling objects occur from high altitude, with the structural expansion and contraction of the telescopic column 402 and the support shaft 403 and the support adjustment, the inclination angle of the top plate 401 can be adjusted within a certain range, which can not only alleviate the impact damage of the falling objects, but also have the effect of hydrophobic shielding on the top of the electromagnetic sound insulation chamber 101 in rainy weather.
