[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a type of high-voltage switchgear, distribution transformer and low-voltage distribution device. For example, patent number CN106992452A discloses a substation that integrates primary and secondary equipment. The prefabricated substation has great practical significance in speeding up the construction cycle, reducing construction costs, reducing land occupation and resource consumption, and protecting the ecological environment.

[0003] At present, many box-type substations are located on the upper part of a fixed platform and are fixedly connected to the platform. However, the drainage pipes and drainage equipment in many places are aging or imperfect. Therefore, many times, especially in summer, when heavy rains occur, the water in the city is serious and waterlogging occurs. When waterlogging occurs, the substation is often flooded or flooded. Therefore, whether it is the water that floods the substation or the water that floods the substation enters the substation, and the drifting objects that follow the flood hit the substation, it will cause damage to the substation. For this reason, a primary and secondary integrated prefabricated substation is proposed. Summary of the Invention

[0004] In order to solve the shortcomings of the prior art, the present invention proposes a primary-secondary integrated prefabricated substation.

[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please refer to Figures 1-9 The present invention provides a technical solution: a primary-secondary integrated prefabricated substation, including a substation body 1, a cabinet door 11 is provided on the substation body 1, and a heat dissipation hole 12 is opened on the cabinet door 11. A support base 2 is provided at the bottom of the substation body 1, and the support base 2 includes a fixedly connected bottom plate 1 21 and a bottom plate 2 22. The four sides of the bottom plate 2 22 are flush with the four sides of the substation body 1. A protective component 3 is installed on the top of the bottom plate 1 21 to protect the substation body 1 and prevent rainwater from entering the inside of the substation body 1 through the heat dissipation holes 12. Two guide limit components 4 are connected between the two sides of the substation body 1 and the substation body 1.

[0029] Furthermore, each component on the substation body 1 is sealed with a seal or seals. When the cabinet door 11 is closed, the heat dissipation holes 12 allow the air inside and outside the substation body 1 to circulate alternately.

[0030] The protective component 3 includes a frame 1 31 fixedly installed on the top of the base plate 1 21 and a square frame 1 32 fixedly sleeved on the outside of the base plate 2 22. The outer sliding sleeve of the square frame 1 32 is provided with a square frame 2 33, and the top of the frame 2 33 is fixedly installed with a frame 2 34.

[0031] An airbag 35 is fixedly installed on the bottom of frame 2 34, and a bellows 36 is fixedly installed on the bottom of the airbag 35. The bottom of the bellows 36 is fixedly connected to the top of frame 1 31. A valve plug 38 is fixedly installed through frame 2 34. The valve plug 38 passes through the top of the airbag 35 and is sealed and fixedly connected to the airbag 35.

[0032] Furthermore, when the airbag 35 is in an expanded state, when drifting objects following the flood hit the airbag 35, the airbag 35 can reduce the impact force, thereby preventing the drifting objects from causing damage to the substation body 1. In daily life, the airbag 35 can reduce the impact of vehicles on the substation body 1, and because the airbag 35 and the bellows 36 have a certain height, the rubber airbag 35 and the bellows 36 have better corrosion resistance than metal materials, and vehicles passing by the substation body 1 can be effectively protected. When the dog defecates, its excrement falls on the airbag 35 and the bellows 36, which can prevent the excrement from directly contacting the substation body 1 and preventing the substation body 1 from being corroded by the excrement. When the airbag 35 is inflated, the second frame 33 and the second frame 34 are outside the cabinet door 11, thereby preventing the cabinet door 11 from being opened from the outside. After that, when the air in the airbag 35 is exhausted, the second frame 34 and the second frame 33 will fall and be under the cabinet door 11, and the cabinet door 11 can be opened at this time.

[0033] When the inflated airbag 35 is moved upward by the buoyancy of the airbag, the previously contracted bellows 36 will be pulled upward by the upward-moving airbag 35 and expanded.

[0034] The valve plug 38 can both perform inflation and exhaust.

[0035] A flexible sealing strip 39 is fixedly mounted on the top of the second frame 34 . The inner side of the flexible sealing strip 39 is slidably connected to the outer side of the substation body 1 . A slope 391 is provided on the top of the flexible sealing strip 39 .

[0036] A water bag 37 is fixedly installed at the bottom of the flexible sealing strip 39, and the inner side of the water bag 37 is slidably connected to the outer side of the substation body 1. A water storage tank 392 is provided on the slope 391, and a plurality of inclined flow channels 1 393 are provided at equal intervals on the inner wall of the bottom of the water storage tank 392. A plurality of flow channels 2 394 connected to the plurality of flow channels 1 393 are provided on the flexible sealing strip 39, and a plurality of water inlet holes 371 are provided on the top of the water bag 37, and the plurality of water inlet holes 371 are respectively connected to the corresponding flow channels 2 394.

[0037] The guide limit assembly 4 includes a screw 41 fixedly mounted on the top of the frame 2 34, a nut 42 is provided on the top threaded sleeve of the screw 41, a mounting seat 43 is provided on the outer sliding sleeve of the screw 41, the mounting seat 43 is fixedly connected to the outer side of the substation body 1, a limiting mechanism 44 is installed on the bottom of the mounting seat 43, and an annular block 45 is provided on the outer fixed sleeve of the screw 41.

[0038] The limiting mechanism 44 includes two supports 441 fixedly installed at the bottom of the mounting base 43, two guide rods 442 fixedly installed between the two supports 441, two clamping blocks 443 are provided between the two supports 441, the two guide rods 442 pass through the two clamping blocks 443 and are slidably connected to the two clamping blocks 443, two springs 444 are provided on the sliding sleeve of the guide rod 442, and the two ends of the spring 444 are respectively fixedly connected to the corresponding supports 441 and the clamping blocks 443, and a semicircular hole 445 is provided on the side where the two clamping blocks 443 are close to each other.

[0039] Arc-shaped slopes 446 are provided on the top and bottom edges of the semicircular hole 445 , and a guide ring 451 with a semicircular cross section is fixedly sleeved on the outer side of the annular block 45 .

[0040] Furthermore, when the annular block 45 is in contact with the clamping block 443, the guide ring 451 will be tangent to the adjacent guide ring 451. With the cooperation of the guide ring 451 and the arc slope 446, when the annular block 45 rises or falls, the two clamping blocks 443 can be pushed away from each other under the elastic force of the corresponding springs 444, so that the annular block 45 can easily pass over the two clamping blocks 443. When the annular block 45 passes over the two clamping blocks 443, the reset elastic force of multiple compressed springs 444 will push the two clamping blocks 443 closer to each other and fit together.

[0041] In this embodiment, when in use, when the multiple cabinet doors 11 on the substation body 1 are in a closed state, air is inflated into the airbag 35 through the valve plug 38, so that the airbag 35 is in an expanded state. During the expansion process of the airbag 35, the second frame 34 and the second box 33 are pushed up, and the four screws 41 pass through the corresponding mounting seats 43. When the air pressure in the airbag 35 is within a certain range, the four nuts 42 can be screwed onto the corresponding screws 41 respectively. At this time, the bottoms of the four nuts 42 will respectively rest on the tops of the corresponding mounting seats 43, and the second frame 34 is located below the heat dissipation hole 12 and between the bottom of the cabinet door 11. At this time, due to the obstruction of the second box 33 and the second frame 34, the cabinet door 11 will not be able to be opened.

[0042] During heavy rain, rainwater falling on the outside of the substation body 1 will flow along the outer wall of the substation body 1 onto the slope 391, then fall into the water storage tank 392 and into the plurality of flow channels 1 393, and then enter the water bag 37 through the flow channel 2 394 and the water inlet hole 371 to be stored.

[0043] When heavy rain continues and flooding occurs, the flood first covers the bottom plate 21 and then gradually rises. The airbag 35 rises due to the buoyancy of the water, and the airbag 35 then pushes the frame 2 34 to rise. The frame 2 34 then pushes the four screws 41 to rise. When the screws 41 drive the annular block 45 to rise, the annular block 45 pushes the two clamping blocks 443 away from each other. When the annular block 45 passes over the two clamping blocks 443, the two clamping blocks 443 will move closer to each other. At the same time, the frame 2 34 drives the flexible sealing strip 39 to rise and pass over the heat dissipation holes 12 on the cabinet door 11. By blocking the heat dissipation holes 12, flood water can be prevented from entering the interior of the substation body 1 through the heat dissipation holes 12.

[0044] When the flood gradually recedes, the force of the screw 41 falling is unable to push the two clamping blocks 443 away from each other. At this time, the liquid level of the flood will be below the frame 2 34. As the flood continues to recede, the buoyancy received by the airbag 35 will continue to decrease. Under the arrangement of the frame 2 33, the frame 2 34, the airbag 35, the flexible sealing strip 39 and the water bag 37, as well as the clean water accumulated in the water bag 37, the four screws 41 will be pulled downward. When the downward pulling force on the screw 41 increases, it will push the two clamping blocks through the annular block 45. 443 move away from each other. When the annular block 45 passes over the two clamping blocks 443, the square frame 2 33, the frame 2 34 and the flexible sealing strip 39 will fall and squeeze the water bag 37. When the water bag 37 is squeezed, the water inside will enter the flow channel 2 394 through the water inlet hole 371 and finally spray out from the flow channel 1 393 and spray obliquely on the outside of the substation body 1. The sprayed clean water can clear the mud attached to the outer surface of the substation body 1, thereby ensuring the cleanliness of the outside of the substation body 1 after the flood.

[0045] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
