Description

Technical Field

[0001] The present application relates to the technical field of substations, and in particular to a high and low voltage prefabricated box-type substation. Background Art

[0002] The substation is a place in the power system where current and voltage are converted. It can also receive and distribute electrical energy, which is of great significance to power transmission. In the related technology, when the substation is in operation, a large amount of heat will be generated inside. In order to ensure the normal operation of the substation, an air inlet is often opened at the bottom of the substation and an air outlet is opened at the top. In this way, the outside air can enter the substation through the air inlet to cool the components inside the substation. At the same time, the air after cooling the components inside the substation comes out from the air outlet at the top, so as to achieve heat dissipation inside the substation. However, when it rains, rainwater gathers quickly on one side of the substation. When the rainwater overflows the air inlet, the rainwater will enter the substation through the air inlet, causing damage to the inside of the substation. Summary of the invention

[0003] In order to improve the waterproof capability of the substation and prevent the substation from being damaged due to rainy days, the present application provides a high and low voltage prefabricated box-type substation.

[0004] The present application provides a high and low voltage prefabricated box-type substation, which adopts the following technical solutions: A high and low voltage prefabricated box-type substation, the substation includes a substation body, a sealing mechanism, a power mechanism, and a drainage mechanism; the substation body has a heat dissipation groove, and the heat dissipation groove has a plurality of heat dissipation holes; the sealing mechanism includes a sealing screw, a sealing slide bar, a sealing block and a sealing bag; the sealing screw is rotatably connected to the side wall of the heat dissipation groove; the sealing slide bar is arranged on the other side wall of the heat dissipation groove, and is symmetrically arranged with the sealing screw about the width direction of the heat dissipation groove; one side of the sealing block is threadedly connected to the sealing screw, and the other side is slidably connected to the sealing slide bar; the substation body also has a liquid inlet, which is used for rainwater to enter, and the liquid inlet is arranged near the bottom of the substation body; the power mechanism is arranged on the substation body, and under the action of rainwater, drives the sealing screw to rotate, and can make the sealing bag expand so as to seal the heat dissipation holes; the drainage mechanism can discharge excess rainwater entering and in the power mechanism.

[0005] By adopting the above technical solution, when it rains, rainwater gathers near the substation body, and the rainwater contacts the power mechanism through the liquid inlet. Under the action of rainwater, the power mechanism is driven to move, and the movement of the power mechanism drives the sealing screw to rotate, and the rotation of the sealing screw drives the sealing block to move, and the sealing block moves on the sealing slide bar. The movement of the sealing block drives the sealing bag to move, and the sealing bag covers the heat dissipation hole. At the same time, the power mechanism blows air into the sealing bag to seal the heat dissipation hole to isolate the rainwater and prevent the rainwater from entering the substation body. After the heat dissipation hole is sealed, the drainage mechanism is opened, and the drainage mechanism can drain the excess rainwater that contacts the power mechanism.

[0006] Optionally, the power mechanism includes a driving assembly and an air blowing assembly; the driving assembly includes a driving block, a blocking block, a rebound member and a driving member; the substation body has a first channel and a second channel; the first channel, the second channel and the liquid inlet are connected, and the driving block is slidably connected in the first channel; the blocking block is arranged on the driving block; wherein, the driving assembly has a sealing state and a driving state; in the sealing state, the blocking block is tightly pressed against the side wall of the second channel; in the driving state, there is a gap between the blocking block and the second channel for rainwater to pass through; the driving member is arranged in the second channel, for driving the sealing screw to rotate; the air blowing assembly is connected to the second channel, for blowing air into the sealing bag.

[0007] By adopting the above technical solution, rainwater enters the first channel through the liquid inlet, and the movement of rainwater drives the driving block to move, and the movement of the driving block drives the blocking block to move. Under the action of rainwater, the driving block continues to move. At this time, there is a gap between the blocking block and the second channel, and rainwater enters the second channel through the gap. Rainwater moves in the second channel, and the movement of rainwater drives the driving member to move. The movement of the driving member drives the sealing screw and the air blowing assembly to move. The movement of the sealing screw causes the sealing block to move, and the movement of the sealing block drives the sealing bag to move, thereby covering the heat dissipation holes. At the same time, the movement of the air blowing assembly causes the sealing bag covering the heat dissipation holes to gradually expand, thereby sealing the heat dissipation holes.

[0008] Optionally, the liquid inlet gradually shrinks from one side away from the first channel to the other side thereof.

[0009] By adopting the above technical solution, rainwater enters the first channel through the liquid inlet. Since the volume from one side of the liquid inlet away from the first channel to the other side thereof continuously decreases, rainwater enters the first channel with a certain pressure, thereby increasing the speed of sealing the heat dissipation hole.

[0010] Optionally, the driving member includes a driving block, a fixed ring, a driving rod, a driving gear ring, a driving gear, a driving ring, a first bevel gear and a second bevel gear; the driving block is slidably connected in the second channel; the side wall of the second channel has a first liquid outlet and a second liquid outlet; the first liquid outlet is used to discharge rainwater; the second liquid outlet is connected to the air blowing component; the fixed ring is connected to the substation body; the driving gear ring is coaxially arranged in the fixed ring; the driving ring is rotatably coaxially arranged in the fixed ring; one end of the driving rod is connected to the driving block; the driving gear is rotatably connected to the other end of the driving rod, and the driving gear is fixedly connected to the driving ring and meshed with the driving gear ring; the first bevel gear is fixedly connected to the side of the driving ring away from the driving gear; the second bevel gear is arranged on the sealing screw, and the first bevel gear is meshed with the second bevel gear.

[0011] By adopting the above technical solution, rainwater enters the second channel through the first channel. At this time, the rainwater has a certain pressure. The rainwater with pressure drives the driving block to move, the movement of the driving block drives the driving rod to move, and the driving of the driving rod drives the gear to move. When the driving block moves to a certain position in the second channel, the first liquid outlet and the second liquid outlet are exposed. At this time, the rainwater can be discharged on one side of the substation body through the first liquid outlet, and the rainwater can also be discharged through the second liquid outlet. The rainwater passing through the second liquid outlet contacts the inflation assembly, and the rainwater causes the inflation assembly to move, and then the sealing bag can be inflated to achieve the sealing of the heat dissipation hole.

[0012] Optionally, the rebound member includes a return spring and a rebound plate; the rebound plate is arranged on a side of the driving block away from the liquid inlet; one end of the return spring is connected to the rebound plate, and the other end is connected to the side wall of the first channel, wherein the movement direction of the return spring is the same as the movement direction of the driving block.

[0013] By adopting the above technical solution, when rainwater enters the first channel through the liquid inlet, the driving block moves in the first channel, and the driving block drives the return spring to be in a compressed state. When rainwater enters the second channel through the first channel and flows out of the second channel, the pressure of rainwater in the first channel decreases, the return spring stretches, and the driving block moves toward the liquid inlet position. At this time, the pressure of rainwater in the second channel also decreases, driving the block to fall back, and the blocking block gradually approaches the second channel. When the blocking block contacts the second channel, rainwater can continue to push the driving block to move, and rainwater enters the second channel through the first channel until the heat dissipation hole is completely blocked. At this time, the drainage mechanism is driven, and excess rainwater in contact with the power mechanism is discharged.

[0014] Optionally, the air inflation assembly includes an air inflation block, a sealing block, an air inflation spring, an air inflation rod, an air inflation plate and an air inflation pipe; the substation body has a third channel, a fourth channel and a fifth channel; the third channel is connected to the second channel; the air inflation block is slidably connected in the third channel; the air inflation plate is slidably connected in the fourth channel, one end of the air inflation rod is connected to the air inflation block, and the other end is connected to the air inflation plate; the sealing block is arranged on the air inflation block; so that the air inflation assembly has a moving state and a returning state; wherein, in the moving state, the air inflation spring contracts; in the returning state, the air inflation spring extends, and the third channel is connected to the fifth channel; one end of the air inflation pipe is connected to the fourth channel, and the other end is connected to the sealing bag.

[0015] By adopting the above technical scheme, rainwater enters the second channel, driving the movement of the block to expose the second liquid outlet, and rainwater enters the third channel through the second channel. The rainwater moves in the third channel, and the movement of the rainwater drives the air inflation block to move. The movement of the air inflation block drives the air inflation rod and the blocking block to move. When the air inflation block drives the air inflation rod to move, the air inflation rod drives the air inflation plate to move, and the air inflation plate moves in the fourth channel. When the air inflation assembly is in a recovery state, the third channel is connected with the fifth channel, and rainwater enters the fifth channel through the third channel. At this time, the air inflation block recovers under the action of the air inflation spring, and the recovery movement of the air inflation block drives the air inflation rod to move, and the movement of the air inflation rod drives the air inflation plate to move, so that the air inflation plate reciprocates in the fourth channel. The gas generated by the reciprocating movement of the air inflation plate enters the sealing bag through the air inflation pipe, so as to realize the inflation of the sealing bag and then realize the sealing of the heat dissipation hole.

[0016] Optionally, the substation also includes a drainage mechanism; the drainage mechanism includes a first drainage member and a second drainage member; the first drainage member includes a first drainage pipe and a first control valve; the first drainage pipe is connected to the second channel and extends out of the substation body; the first control valve is arranged on the first drainage pipe; the second drainage member includes a second drainage pipe and a second control valve; the second drainage pipe is connected to the third channel and extends out of the substation body; the second control valve is arranged on the second drainage pipe.

[0017] By adopting the above technical solution, when the rainwater flow rate is high (or the heat dissipation hole is sealed), and it is necessary to slow down the rainwater (or drain the excess rainwater), the driving block moves in the second channel, and the movement of the driving block exposes the first liquid outlet and the second liquid outlet. At this time, the first control valve is opened, and the rainwater can be discharged through the first drainage pipe to prevent the rainwater flow rate from being too high; similarly, when the rainwater flow rate is too low, the first control valve can be closed, and at this time, all the rainwater flows out through the second liquid outlet, and the heat dissipation hole can be quickly sealed. At the same time, when the air pressure inside the sealing bag is sufficient (re-inflation may cause the risk of explosion), the second control valve can be opened. When the second control valve is opened, the rainwater entering the third channel can be quickly discharged through the second drainage pipe.

[0018] Optionally, the substation further includes a blocking mechanism; the blocking mechanism includes a blocking plate and a power assembly; the blocking plate is movably disposed at the liquid inlet through the power assembly; the blocking plate is used to block the liquid inlet.

[0019] By adopting the above technical solution, the power component is turned on, and the power component drives the sealing plate to move. The power component drives the sealing plate to move, and the sealing plate can be opened quickly to allow rainwater to contact the power mechanism to achieve sealing of the heat dissipation hole.

[0020] Optionally, the power assembly includes a power plate, a power gear, a power rack, a power roller, a traction rope, a power motor and an elastic member; the top of the substation body is provided with a water collecting trough; the power plate is arranged in the water collecting trough through the elastic member; the power rack is connected to the power plate; the power roller is rotatably connected to the substation body; the power gear is arranged on the power roller and meshes with the power rack; the traction rope is wound around the power roller, and the sealing plate is connected to the traction rope.

[0021] By adopting the above technical solution, when it rains, rainwater falls into the water collection tank, and the force of the falling rainwater drives the power plate to move, the movement of the power plate drives the movement of the power rack, the movement of the power rack drives the movement of the power gear, the movement of the power gear drives the movement of the power roller, the power roller drives the movement of the traction rope, the traction rope drives the blocking plate to move, at this time the blocking plate is opened, the rainwater contacts the power mechanism, and the heat dissipation hole is blocked. After the rain, the elastic member resumes movement, at this time the power plate drives the movement of the power rack, the movement of the power rack drives the movement of the power gear, the movement of the power gear drives the movement of the power roller, the power roller drives the movement of the traction rope, the traction rope drives the movement of the blocking plate, and at this time the blocking plate is closed.

[0022] Optionally, the sealing bag has a protrusion; when the sealing bag is inflated, the protrusion extends into the heat dissipation hole and has an interference fit with the side wall of the heat dissipation hole.

[0023] By adopting the above technical solution, when the sealing bag covers the heat dissipation hole, the protrusion corresponds to the heat dissipation hole, and the air blowing component blows air into the sealing bag. At this time, the protrusion expands and extends into the heat dissipation hole, thereby achieving better sealing of the heat dissipation hole and preventing rainwater from entering the interior of the substation body and causing damage to the device.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The power mechanism is driven to move under the action of rainwater, and the movement of the power mechanism drives the sealing screw to rotate, and the rotation of the sealing screw drives the sealing block to move, and the sealing block moves on the sealing slide bar, and the movement of the sealing block drives the sealing bag to move, and the sealing bag covers the heat dissipation hole. At the same time, the power mechanism blows air into the sealing bag to seal the heat dissipation hole to isolate the rainwater and prevent the rainwater from entering the substation body. After the heat dissipation hole is sealed, the drainage mechanism is opened, and the drainage mechanism can drain the excess rainwater that contacts the power mechanism.

[0025] 2. The movement of rainwater drives the driving block to move, and the movement of the driving block drives the blocking block to move. Under the action of rainwater, the driving block continues to move. At this time, there is a gap between the blocking block and the second channel, and the rainwater enters the second channel through the gap. The rainwater moves in the second channel, and the movement of rainwater drives the driving member to move. The movement of the driving member drives the sealing screw and the air blowing assembly to move. The movement of the sealing screw causes the sealing block to move, and the movement of the sealing block drives the sealing package to move, thereby covering the heat dissipation holes. At the same time, the movement of the air blowing assembly causes the sealing package covering the heat dissipation holes to gradually expand, thereby sealing the heat dissipation holes.

[0026] 3. The driving block is driven to move by the pressurized rainwater, and the movement of the driving block drives the driving rod to move, and the driving of the driving rod drives the gear to move. When the driving block moves to a certain position in the second channel, the first liquid outlet and the second liquid outlet are exposed. At this time, the rainwater can be discharged on one side of the substation body through the first liquid outlet, and the rainwater can also be discharged through the second liquid outlet. The rainwater passing through the second liquid outlet contacts the inflation assembly, and the rainwater causes the inflation assembly to move, thereby inflating the sealing bag to achieve sealing of the heat dissipation holes.

[0027] 4. By opening the first control valve, rainwater can be discharged through the first drainage pipe to prevent the phenomenon of excessive rainwater flow rate; similarly, when the rainwater flow rate is too low, the first control valve can be closed, and at this time, all the rainwater flows out through the second liquid outlet, which can quickly seal the heat dissipation hole. At the same time, when the air pressure inside the sealing bag is sufficient (re-inflation may cause the risk of explosion), the second control valve can be opened, and the second control is opened. At this time, the rainwater entering the third channel can be quickly discharged through the second drainage pipe. BRIEF DESCRIPTION OF THE DRAWINGS

With such a configuration, on the one hand, it can prevent rainwater from entering the substation body 1 and causing damage to the substation, and on the other hand, the heat dissipation hole 12 is closed by rainwater self-driving, which helps to reduce energy consumption.

[0043] See also Figures 3 to 5 In some embodiments of the present disclosure, the power mechanism 3 includes a driving assembly 31 and an air blowing assembly 32; the driving assembly 31 includes a driving block 311, a blocking block 312, a rebound member 313 and a driving member 314; the substation body 1 has a first channel 14 and a second channel 15; the first channel 14, the second channel 15 and the liquid inlet 13 are connected, wherein the length direction of the first channel 14 is perpendicular to the length direction of the second channel 15, and the driving block 311 is slidably connected in the first channel 14; the blocking block 312 is arranged on the driving block 311; in the embodiment of the present disclosure, the driving assembly 31 has a sealing state and a driving state; in In the sealed state, the blocking block 312 is pressed against the side wall of the second channel 15, so that when rainwater enters the first channel 14 through the liquid inlet 13, the rainwater will not immediately enter the second channel 15, but push the driving block 311 to move; so that the driving component 31 changes to the driving state, when the driving component 31 is in the driving state, there is a gap between the blocking block 312 and the second channel 15 for rainwater to pass through, so that rainwater can enter the second channel 15; the driving member 314 is installed in the second channel 15, used to drive the sealing screw 21 to rotate; the air blowing component 32 is connected to the second channel 15, and is used to blow air into the sealing bag 24.

[0044] See also Figure 5In some embodiments of the present disclosure, the liquid inlet 13 gradually shrinks from one side away from the first channel 14 to the other side thereof. In this way, when rainwater enters the first channel 14 through the liquid inlet 13, the path of the rainwater changes, and the rainwater has a certain pressure, so that the heat dissipation hole 12 can be quickly sealed.

[0045] See also Figures 3 to 6 In some embodiments of the present disclosure, the driving member 314 includes a driving block 3141, a fixed ring 3142, a driving rod 3143, a driving gear ring 3144, a driving gear 3145, a driving ring 3146, a first bevel gear 3147 and a second bevel gear 3148; the driving block 3141 is slidably connected to the second channel 15; the side wall of the second channel 15 has a first liquid outlet 151 and a second liquid outlet 152; the first liquid outlet 151 is used to discharge rainwater; the second liquid outlet 152 is connected to the air blowing assembly 32. It can be understood that when rainwater enters the second channel 15, the rainwater can drive the driving block 3141 to move, and the driving block 3141 moves in the second channel 15. When the driving block 3141 moves to a certain position, the first liquid outlet 151 and the second liquid outlet 152 can be exposed. The fixed ring 3142 is connected to the substation body 1; the driving ring gear 3144 is coaxially arranged in the fixed ring 3142; the driving ring 3146 is rotatably coaxially arranged in the fixed ring 3142; one end of the driving rod 3143 is connected to the driving block 3141, wherein the axial direction of the driving rod 3143 is the same as the length direction of the second channel 15; the driving gear 3145 is rotatably connected to the other end of the driving rod 3143, the driving gear 3145 is fixedly connected to the driving ring 3146, and the driving gear 3145 is meshed with the driving ring gear 3144; the first bevel gear 3147 is fixedly connected to the side of the driving ring 3146 away from the driving gear 3145; the second bevel gear 3148 is installed on the sealing screw 21, and the first bevel gear 3147 is meshed with the second bevel gear 3148.

[0046] Specifically, when the driving block 3141 moves in the second channel 15, the driving block 3141 drives the driving rod 3143 to move, the movement of the driving rod 3143 drives the driving gear 3145 to move in an annular manner on the driving gear ring 3144, the movement of the driving gear 3145 drives the driving ring 3146 to rotate, the rotation of the driving ring 3146 drives the first bevel gear 3147 to rotate, the rotation of the first bevel gear 3147 drives the second bevel gear to rotate, thereby driving the rotation of the sealing screw 21, and the sealing of the heat dissipation hole 12 is achieved through the sealing bag 24. It can be understood that the reciprocating movement of the driving block 3141 in the second channel 15 can achieve the reciprocating movement of the driving rod 3143, the driving rod 3143 is connected to the driving gear 3145 through a connecting rod, so that the driving gear 3145 can be rotated in one direction, and then the driving ring 3146 can drive the first bevel gear 3147 to rotate in the same direction until the sealing bag 24 covers the heat dissipation hole 12.

[0047] See also Figure 5 In some embodiments of the present disclosure, the resilient member 313 includes a return spring 3131 and a resilient plate 3132; the resilient plate 3132 is installed on the side of the driving block 311 away from the liquid inlet 13; one end of the return spring 3131 is connected to the resilient plate 3132, and the other end of the return spring 3131 is connected to the side wall of the first channel 14, wherein the movement direction of the return spring 3131 is the same as the movement direction of the driving block 311. In this way, the reciprocating movement of the driving block 311 in the first channel 14 can be achieved, and rainwater can intermittently enter the second channel 15, so as to achieve the reciprocating movement of the driving block 3141 in the second channel 15.

[0048] See also Figures 3 to 5 In some embodiments of the present disclosure, the air blowing assembly 32 includes an air blowing block 321, a blocking block 322, an air blowing spring 323, an air blowing rod 324, an air blowing plate 325 and an air blowing pipe 326; the substation body 1 has a third channel 16, a fourth channel 17 and a fifth channel 18; wherein the third channel 16 is connected to the second channel 15; the air blowing block 321 is slidably connected to the third channel 16; the air blowing plate 325 is slidably connected to the fourth channel 17, and the air blowing rod 324 is connected to the fourth channel 17. One end of the air inflation rod 324 is connected to the air inflation block 321, and the other end of the air inflation rod 324 is connected to the air inflation plate 325; the blocking block 322 is installed on the air inflation block 321; so that the air inflation component 32 has a moving state and a return state; wherein, in the moving state, the air inflation spring 323 contracts; in the return state, the air inflation spring 323 extends, and the third channel 16 is connected to the fifth channel 18; one end of the air inflation pipe 326 is connected to the fourth channel 17, and the other end is connected to the sealing bag 24.

[0049] It can be understood that the rainwater in the second channel 15 enters the third channel 16, and the rainwater pushes the air-inflating block 321 to slide in the third channel 16. At this time, the air-inflating spring 323 is gradually in a compressed state, and the movement of the air-inflating block 321 drives the air-inflating rod 324 to move, and the movement of the air-inflating rod 324 drives the air-inflating plate 325 to move; at the same time, the movement of the air-inflating block 321 drives the blocking block 322 to move. When the blocking block 322 moves to a certain position, the third channel 16 is connected to the fifth channel 18. At this time, the rainwater flows from the fifth channel 18 to the third channel 18. The air spring 323 is in an extended state at this time, and the air block 321 moves in the opposite direction. The movement of the air block 321 drives the air rod 324 to move, and the movement of the air rod 324 drives the air plate 325 to move. In this way, the air plate 325 moves back and forth in the fourth channel 17, and then can generate air pressure in the fourth channel 17 to expand the sealing bag 24. The air pressure generated in the fourth channel 17 enters the sealing bag 24 through the air pipe 326, thereby expanding the sealing bag 24 and sealing the heat dissipation hole 12.

[0050] See also Figures 3 to 5 In some embodiments of the present disclosure, the drainage mechanism 4 includes a first drainage member 41 and a second drainage member 42; the first drainage member 41 includes a first drainage pipe 411 and a first control valve 412; the first drainage pipe 411 is connected to the second channel 15 and extends out of the substation body 1, and the first control valve 412 is arranged on the first drainage pipe 411.

[0051] It is understandable that when the sealing bag 24 is already in a sealed state for the heat dissipation hole 12 (but there is a phenomenon that rainwater from the outside contacts the power mechanism 3 through the liquid inlet 13, which may cause the sealing bag 24 to swell and be damaged), the first control valve 412 can be opened, and when rainwater enters the second channel 15 through the first channel 14, part of the rainwater can be discharged through the first drainage pipe 411. The second drainage member 42 includes a second drainage pipe 421 and a second control valve 422. The second drainage pipe 421 is connected to the third channel 16 and extends out of the substation body 1; the second control valve 422 is arranged on the second drainage pipe 421.

[0052] It is understandable that part of the rainwater is discharged through the first drainage pipe 411, and part of the rainwater enters the third channel 16. At this time, the second control valve 422 is opened, and when the rainwater enters the third channel 16, the rainwater can be quickly sent out through the second drainage pipe 421, so that the air blowing component 32 will no longer generate related gas. This allows the sealing bag 24 to be protected while the heat dissipation hole 12 is sealed.

[0053] See also Figure 1 , Figure 7 ,as well as Fig. 9In some embodiments of the present disclosure, the blocking mechanism 5 includes a blocking plate 51 and a power assembly 52; the blocking plate 51 can be movably installed at the liquid inlet 13 through the power assembly 52; the blocking plate 51 is used to block the liquid inlet 13.

[0054] It should be noted that the sealing plate 51 described in the embodiment of the present disclosure is in a closed state on a sunny day. It can be understood that on a sunny day, the liquid inlet 13 is blocked by the sealing plate 51, thereby preventing foreign objects from entering the substation body 1 through the liquid inlet 13 and causing damage to the substation body 1.

[0055] See also Figure 1 , Figure 2 , Fig. 9 In some embodiments of the present disclosure, the power assembly 52 includes a power plate 521, a power gear 522, a power rack 523, a power roller 524, a traction rope 525 and an elastic member 526; the top of the substation body 1 has a water collecting trough 19; as an example, the water collecting trough 19 can be inclined, and the power plate 521 is arranged on the lower side of the water collecting trough 19 through the elastic member 526; the power rack 523 is connected to the power plate 521; the power roller 524 is rotatably connected to the substation body 1; the power gear 522 is arranged on the power roller 524, and the power gear 522 is meshed with the power rack 523; the traction rope 525 is wound around the power roller 524, and the connection between the sealing plate 51 and the traction rope 525 is blocked.

[0056] As an example, the elastic member 526 can be set as a spring (not specifically marked in the drawings of the present application); wherein one end of the spring is fixedly connected to the side wall of the water collecting trough 19, and the other end is connected to the power plate 521, and the movement direction of the spring is the same as the height direction of the substation body 1.

[0057] Furthermore, in other disclosed embodiments, the substation is also provided with a pointed cone (not specifically marked in the drawings of the present application). Specifically, when it rains, rainwater slides down the pointed cone into the water collecting trough 19, and the rainwater contacts the power plate 521, and the power plate 521 moves, and the movement of the power plate 521 drives the movement of the power rack 523, and the movement of the power rack 523 drives the movement of the power gear 522, and the power gear 522 drives the movement of the power roller 524, and the traction rope 525 moves, and the movement of the traction rope 525 drives the blocking plate 51 to move, and the blocking plate 51 opens to facilitate the contact of rainwater with the power mechanism 3, so that the heat dissipation hole 12 is sealed by the action of rainwater on the power mechanism 3.

[0058] See also Figure 8Further, as an example, the sealing bag 24 has a protrusion 241; when the sealing bag 24 is inflated, the protrusion 241 extends into the heat dissipation hole 12, and the protrusion 241 and the side wall of the heat dissipation hole 12 are interference-fitted. In this way, the isolation effect of the heat dissipation hole 12 and rainwater can be further improved.
