[0002] In the basic field of electric power, a box-type substation is a common device. Most modern box-type substations are composed of a rectangular metal box. Box-type substations are usually placed outdoors. Since the heat in the box-type substation needs to be conducted to the outside in time, otherwise, damage will be caused to the power transformation components due to excessive heat accumulation, and then the box-type substation will be in a paralyzed state, making it unable to perform the power distribution work normally.

Detailed implementation manners

[0030] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the following further details the present invention in conjunction with specific embodiments.

[0031] A box-type substation proposed in this embodiment, as Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, includes a box-type substation body 1. A base 2 is fixedly connected to the bottom of the box-type substation body 1. An exhaust structure is provided at the top of the box-type substation body 1. A plurality of groups of intake air filtering components are provided at the bottom end of the box-type substation body 1. Each group of intake air filtering components includes a sealing cover 7 disposed below the box-type substation body 1. Above the sealing cover 7, there are two intake pipes 3 located inside the box-type substation body 1;

[0032] At the top of the intake pipe 3, an intake fan 4 is in contact. The box-type substation body 1 is equipped with a fixing unit respectively adapted to the intake pipe 3 and the intake fan 4. A plurality of avoidance holes 5 adapted to the intake pipe 3 are opened on the bottom inner wall of the box-type substation body 1. A first filter screen 6 is provided in the avoidance hole 5, and the number of the first filter screens 6 and the intake pipes 3 is the same. The intake pipe 3 is equipped with an elastic support member adapted to the first filter screen 6. The box-type substation body 1 is equipped with an adjustment structure for changing the position of the sealing cover 7. The sealing cover 7 is equipped with a pushing member for driving the first filter screen 6 to shake in the vertical direction; when the intake fan 4 is started, the air outside the box-type substation body 1 is pumped into the box-type substation body 1 through the first filter screen 6 and the intake pipe 3 by the intake fan 4. The original air in the box-type substation body 1 is discharged through the exhaust structure. When it is necessary to clean the dust on the first filter screen 6, the sealing cover 7 is driven to move through the adjustment structure. The sealing cover 7 drives the pushing member to move to the lower side of the first filter screen 6. The first filter screen 6 is pushed by the pushing member to slide from the avoidance hole 5 into the intake pipe 3. Then, the pushing member no longer supports the first filter screen 6. The elastic support member drives the first filter screen 6 to move down to the lowest position and stop, so that the dust at the bottom of the first filter screen 6 shakes off. When it is not necessary to perform air exchange and heat dissipation in the box-type substation body 1, the sealing cover 7 is driven to move through the adjustment structure, so that the sealing cover 7 seals the avoidance hole 5, and the dust adsorbed on the first filter screen 6 can be cleaned, avoiding affecting the air exchange efficiency and ensuring that the heat dissipation efficiency is within the preset range.

[0033] In some optional specific embodiments, such as Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown in the figure, the adjustment structure includes a rotating shaft 8 fixedly installed on the top of the sealing cover 7. A rotating sleeve 9 located inside the box-type substation body 1 is sleeved outside the rotating shaft 8. The bottom end of the rotating sleeve 9 is rotatably connected to the inner wall of the bottom of the box-type substation body 1. Two guiding grooves 10 are formed on the inner wall of the rotating sleeve 9. Two guiding strips 11 are fixedly connected to the rotating shaft 8, and the guiding strips 11 penetrate through the corresponding guiding grooves 10. The box-type substation body 1 is equipped with a driver for driving the rotation of the rotating sleeve 9, and the box-type substation body 1 is equipped with a supporting unit for driving the vertical movement of the rotating shaft 8. The driver includes a supporting part 12 fixedly installed inside the box-type substation body 1. A hydraulic telescopic rod 13 is fixedly installed on the supporting part 12. The telescopic end of the hydraulic telescopic rod 13 is fixedly connected with a toothed plate 14. A gear 15 is fixedly sleeved outside the rotating sleeve 9, and the toothed plate 14 meshes with the gear 15. The supporting unit includes a rotating plate 16 fixedly installed at the top end of the rotating shaft 8. At least one first supporting column 17 is fixedly connected to the bottom of the rotating plate 16. A supporting ring 18 located below the rotating plate 16 is arranged inside the box-type substation body 1. The supporting ring 18 and the inner wall of the box-type substation body 1 are connected by a plurality of first connecting columns 19. A plurality of bumps 20 adapted to the first supporting columns 17 are fixedly connected to the top of the supporting ring 18, and arc-shaped surfaces adapted to the first supporting columns 17 are respectively arranged on both sides of the bumps 20. Two sealing gaskets 29 adapted to the avoidance holes 5 are fixedly connected to the top of the sealing cover 7. The pushing member includes two rotating frames 21 fixedly installed at the bottom of the sealing cover 7. An active frame 23 is arranged above the rotating frames 21. A plurality of second supporting columns 24 are fixedly connected to the top of the active frame 23. A fixed block 22 is fixedly connected to the bottom of the rotating frame 21. A first sliding groove 25 is formed on the top of the fixed block 22. A first sliding block 26 is slidably arranged in the first sliding groove 25. The bottom of the first sliding block 26 and the inner wall of the bottom of the first sliding groove 25 are connected by a plurality of first compression springs 27. The top of the first sliding block 26 and the bottom of the active frame 23 are connected by a second connecting column 28. The elastic supporting member includes a plurality of supporting blocks 30 fixedly installed in the air inlet pipe 3. A groove 31 is formed on the bottom of the supporting block 30. A prism 32 is arranged in the groove 31. The bottom end of the prism 32 is fixedly connected to the top of the first filter screen 6. The top end of the prism 32 and the inner wall of the top of the groove 31 are connected by a second compression spring 33. Second sliding grooves 34 are respectively formed on the inner walls of both sides of the groove 31. Second sliding blocks 35 are slidably arranged in the second sliding grooves 34, and the second sliding blocks 35 are fixedly connected to the corresponding prisms 32;

[0034] The hydraulic telescopic rod 13 drives the movement of the toothed plate 14. The toothed plate 14 drives the rotation of the rotating sleeve 9 through the gear 15. The rotating sleeve 9 drives the rotation of the rotating shaft 8 and the sealing cover 7 through the guide bar 11. The sealing cover 7 drives the rotation of the rotating frame 21. When the rotating frame 21 drives the movable frame 23 to rotate to the lower part of the first filter screen 6, with the continuous movement of the rotating shaft 8, the rotating shaft 8 drives the bottom end of the first support column 17 to slide from the top of the support ring 18 to the arc surface of the convex block 20 through the rotating plate 16. The convex block 20 supports the upward movement of the first support column 17, the rotating plate 16 and the rotating shaft 8. The rotating shaft 8 drives the guide bar 11 to slide relative to the guide groove 10 and the rotating sleeve 9, and the rotating shaft 8 drives the rotating frame 21 and the movable frame 23 to move upward. The movable frame 23 supports the upward movement of the first filter screen 6 relative to the air inlet pipe 3 through the second support column 24. The prism 32 slides relative to the groove 31. The second compression spring 33 is in a compressed state, and the second slider 35 slides in the second chute 34. When the first filter screen 6 moves upward to the preset position, the hydraulic telescopic rod 13 drives the toothed plate 14 to move in the reverse direction, so that the rotating shaft 8 drives the rotating plate 16 to rotate in the reverse direction. The bottom end of the first support column 17 contacts the top of the support ring 18 again. The movable frame 23 and the second support column 24 no longer support the first filter screen 6. The second compression spring 33 drives the prism 32 and the first filter screen 6 to move downward. When the first filter screen 6 descends to the lowest position, the bottom of the second slider 35 contacts the inner wall of the bottom of the second chute 34, so that the dust located at the bottom of the first filter screen 6 shakes off. The first filter screen 6 slides into the avoidance hole 5 again. When heat dissipation is not required, the hydraulic telescopic rod 13 drives the toothed plate 14 to rotate continuously, so that the sealing cover 7 rotates to the lower part of the avoidance hole 5. With the continuous rotation of the sealing cover 7, the bottom end of the first support column 17 slides from the top of the support ring 18 to the arc surface of another convex block 20. The rotating shaft 8 drives the sealing cover 7 to move upward, so that the sealing gasket 29 is closely attached to the bottom of the box-type substation body 1. The avoidance hole 5 is sealed by the sealing gasket 29 and the sealing cover 7. During the upward movement of the sealing cover 7, the top end of the second support column 24 first contacts the bottom of the box-type substation body 1. The movable frame 23, the second support column 24, the first slider 26 and the second connecting column 28 remain stationary relative to the box-type substation body 1. With the continuous upward movement of the sealing cover 7, the sealing cover 7 drives the rotating frame 21 and the fixed block 22 to move upward relative to the second connecting column 28 and the first slider 26. The first compression spring 27 is in a compressed state.

[0035] In some optional specific embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, the fixing unit includes first mounting plates 36 fixedly installed on both sides of the intake pipe 3 respectively. Second mounting plates 37 are fixedly connected to both sides of the intake fan 4 respectively. A number of positioning plates 38 are fixedly connected to the bottom inner wall of the box-type substation body 1. Positioning holes 39 adapted to the positioning plates 38 are respectively formed on the first mounting plates 36 and the second mounting plates 37, and the positioning plates 38 respectively penetrate through the positioning holes 39 on the first mounting plates 36 and the second mounting plates 37. Fixing plates 40 are respectively arranged on both sides of the intake pipe 3. The bottom ends of the fixing plates 40 are fixedly connected to the bottom inner wall of the box-type substation body 1. Movable plates 42 are respectively arranged on the sides of the two fixing plates 40 away from each other. The movable plates 42 and the fixing plates 40 are connected by a number of tension springs 43. Two baffle plates 41 penetrate through the fixing plates 40, and the baffle plates 41 are fixedly connected to the corresponding movable plates 42. The bottoms of the two baffle plates 41 are respectively in contact with the tops of the first mounting plate 36 and the second mounting plate 37. A handle 44 is fixedly connected to the side of the movable plate 42 away from the fixing plate 40. The exhaust structure includes a shielding cover 47 arranged above the box-type substation body 1. The shielding cover 47 and the box-type substation body 1 are connected by a number of third connecting columns 48. A number of exhaust pipes 45 located below the shielding cover 47 are arranged at the top end of the box-type substation body 1, and a second filter screen 46 is fixedly connected inside the exhaust pipes 45;

[0036] When the staff needs to remove the intake pipe 3, the first filter screen 6 and the intake fan 4, the staff drives the movable plate 42 and the baffle plate 41 to move relative to the fixing plate 40 through the handle 44, so that the bottoms of the two baffle plates 41 are no longer in contact with the tops of the first mounting plate 36 and the second mounting plate 37 respectively, and the tension springs 43 are in a stretched state, releasing the limitation of the positions of the first mounting plate 36 and the second mounting plate 37. The staff drives the intake fan 4 to move upward, so that the positioning hole 39 on the second mounting plate 37 is separated from the positioning plate 38, and the removal of the intake fan 4 is completed. Then the staff drives the intake pipe 3 to move upward, the positioning hole 39 on the first mounting plate 36 is separated from the positioning plate 38, and the first filter screen 6 is withdrawn from the avoidance hole 5, and the removal of the intake pipe 3 and the first filter screen 6 can be completed. The air in the box-type substation body 1 is discharged through the exhaust pipe 45 and the second filter screen 46. Through the design of the shielding cover 47 and the third connecting columns 48, the second filter screen 46 can be shielded.

[0037] Working principle: Start the intake fan 4. The air outside the box-type substation body 1 is pumped into the box-type substation body 1 through the first filter screen 6 and the intake pipe 3 by the intake fan 4. The original air in the box-type substation body 1 is discharged through the exhaust structure. When it is necessary to clean the dust on the first filter screen 6, the adjustment structure is used to drive the sealing cover 7 to move. The sealing cover 7 drives the pushing member to move to the lower part of the first filter screen 6. The first filter screen 6 is pushed by the pushing member to slide from the avoidance hole 5 into the intake pipe 3. Then, the pushing member no longer supports the first filter screen 6, and the elastic support member drives the first filter screen 6 to move down to the lowest position and stop, so that the dust at the bottom of the first filter screen 6 shakes off. When it is not necessary to ventilate and dissipate heat in the box-type substation body 1, the adjustment structure is used to drive the sealing cover 7 to move, so that the sealing cover 7 seals the avoidance hole 5, and the dust adsorbed on the first filter screen 6 can be cleaned to avoid affecting the ventilation efficiency and ensure that the heat dissipation efficiency is within the preset range;

[0038] The hydraulic telescopic rod 13 drives the tooth plate 14 to move. The tooth plate 14 drives the rotating sleeve 9 to rotate through the gear 15. The rotating sleeve 9 drives the rotating shaft 8 and the sealing cover 7 to rotate through the guide bar 11. The sealing cover 7 drives the rotating frame 21 to rotate. When the rotating frame 21 drives the movable frame 23 to rotate to the lower side of the first filter screen 6, with the continuous movement of the rotating shaft 8, the rotating shaft 8 drives the bottom end of the first support column 17 to slide from the top of the support ring 18 to the arc surface of the convex block 20. The convex block 20 supports the first support column 17, the rotating plate 16 and the rotating shaft 8 to move upward. The rotating shaft 8 drives the guide bar 11 to slide relative to the guide groove 10 and the rotating sleeve 9, and the rotating shaft 8 drives the rotating frame 21 and the movable frame 23 to move upward. The movable frame 23 supports the first filter screen 6 to move upward relative to the air inlet pipe 3 through the second support column 24. The prism 32 slides relative to the groove 31. The second compression spring 33 is in a compressed state, and the second slider 35 slides in the second chute 34. When the first filter screen 6 moves upward to the preset position, the hydraulic telescopic rod 13 drives the tooth plate 14 to move in the reverse direction, so that the rotating shaft 8 drives the rotating plate 16 to rotate in the reverse direction. The bottom end of the first support column 17 contacts the top of the support ring 18 again. The movable frame 23 and the second support column 24 no longer support the first filter screen 6. The second compression spring 33 drives the prism 32 and the first filter screen 6 to move downward. When the first filter screen 6 descends to the lowest position, the bottom of the second slider 35 contacts the inner wall of the bottom of the second chute 34, so that the dust located at the bottom of the first filter screen 6 shakes off. The first filter screen 6 slides into the avoidance hole 5 again. When heat dissipation is not required, the hydraulic telescopic rod 13 drives the tooth plate 14 to rotate continuously, so that the sealing cover 7 rotates to the lower side of the avoidance hole 5. With the continuous rotation of the sealing cover 7, the bottom end of the first support column 17 slides from the top of the support ring 18 to the arc surface of another convex block 20. The rotating shaft 8 drives the sealing cover 7 to move upward, so that the sealing gasket 29 is closely attached to the bottom of the box-type substation body 1. The avoidance hole 5 is sealed by the sealing gasket 29 and the sealing cover 7. During the upward movement of the sealing cover 7, the top end of the second support column 24 first contacts the bottom of the box-type substation body 1. The movable frame 23, the second support column 24, the first slider 26 and the second connecting column 28 remain stationary relative to the box-type substation body 1. With the continuous upward movement of the sealing cover 7, the sealing cover 7 drives the rotating frame 21 and the fixed block 22 to move upward relative to the second connecting column 28 and the first slider 26. The first compression spring 27 is in a compressed state;

[0039] When the staff needs to remove the intake pipe 3, the first filter screen 6 and the intake fan 4, the staff drives the movable plate 42 and the baffle plate 41 to move relative to the fixed plate 40 through the handle 44, so that the bottoms of the two baffle plates 41 no longer contact the tops of the first mounting plate 36 and the second mounting plate 37 respectively, and the tension spring 43 is in a stretched state, releasing the limitation on the positions of the first mounting plate 36 and the second mounting plate 37. The staff drives the intake fan 4 to move upward, so that the positioning hole 39 on the second mounting plate 37 disengages from the positioning plate 38, completing the removal of the intake fan 4. Then the staff drives the intake pipe 3 to move upward, the positioning hole 39 on the first mounting plate 36 disengages from the positioning plate 38, and the first filter screen 6 is withdrawn from the avoidance hole 5, and the removal of the intake pipe 3 and the first filter screen 6 can be completed. The air in the box-type substation body 1 is discharged through the exhaust pipe 45 and the second filter screen 46. Through the design of the shielding cover 47 and the third connecting column 48, the second filter screen 46 can be shielded.
