Description

Technical Field

[0001] The invention relates to the field of flood prevention in power distribution stations, and in particular to a power distribution station flood prevention device applied to the power distribution station. Background Art

[0002] At present, flood control in power distribution stations mostly uses waterproof baffles, and the waterproof baffles are generally temporarily installed. Before the flood season arrives, manual labor is used to install waterproof baffles at the bottom of the access door of the power distribution station, and waterproof strips need to be set between the bottom of the waterproof baffle and the ground, and between the side of the waterproof baffle and the side wall of the access door, so that the bottom of the waterproof baffle is sealed with the ground, and the side of the waterproof baffle is sealed with the side wall of the access door. After the flood season, manual labor is required to remove it on site. At present, this kind of temporarily installed waterproof baffle is not only inconvenient to install and disassemble, but also easy to cause rainwater to enter the power distribution station due to problems such as missing waterproof strips or improper installation, and the equipment is short-circuited due to water ingress. If the waterproof baffle is set as a permanent baffle, it will affect the daily inspection and maintenance work of the staff, especially causing great inconvenience when carrying equipment. Summary of the invention

[0003] The purpose of the present invention is to provide a power distribution station anti-flooding device which can effectively prevent rainwater from entering the power distribution station when the flood season comes without affecting the daily inspection and maintenance work and equipment handling of the staff.

[0004] The technical solution of the present invention is:

[0005] A flood control device for a power distribution station comprises an air pump, an outer rotating flood control baffle arranged at the bottom of an inlet and outlet door of the power distribution station by rotating through a first rotating shaft, an inner rotating flood control baffle arranged at the bottom of the inlet and outlet door of the power distribution station by rotating through a second rotating shaft, a connecting rope connecting the outer rotating flood control baffle and the inner rotating flood control baffle, a flood control isolation air bag bag accommodating groove and an auxiliary support air bag bag accommodating groove arranged on the ground of the inlet and outlet door of the power distribution station, a flood control isolation air bag bag arranged in the flood control isolation air bag bag accommodating groove, and an auxiliary support air bag bag arranged in the auxiliary support air bag bag accommodating groove, the first rotating shaft and the second rotating shaft are located between inner and outer door frames of the inlet and outlet door, the first rotating shaft is close to the outer door frame of the inlet and outlet door, the second rotating shaft is close to the inner door frame of the inlet and outlet door, the flood control isolation air bag bag accommodating groove is located between the first rotating shaft and the second rotating shaft, the auxiliary support air bag bag accommodating groove and the flood control isolation air bag bag accommodating groove are located on both sides of the second rotating shaft, and the air pump is connected with the flood control isolation air bag bag and the auxiliary support air bag bag through an air supply pipeline;

[0006] When the inner rotating flood prevention baffle and the outer rotating flood prevention baffle are both in a lying state, the inner rotating flood prevention baffle is located below the outer rotating flood prevention baffle, and the inner rotating flood prevention baffle blocks the notch of the auxiliary support airbag bag accommodating slot, and the outer rotating flood prevention baffle blocks the notch of the flood isolation airbag bag accommodating slot.

[0007] When the air pump inflates the flood control isolation airbag bag and the auxiliary support airbag bag through the air supply pipeline, during the process of expanding the flood control isolation airbag bag and the auxiliary support airbag bag, the auxiliary support airbag bag will push the inner rotating flood control baffle to rotate upward around the second rotation axis, and the inner rotating flood control baffle will push the outer rotating flood control baffle to rotate upward around the first rotation axis; the flood control isolation airbag bag will be inflated between the inner rotating flood control baffle and the outer rotating flood control baffle; when the flood control isolation airbag is inflated, the connecting rope is in a straight state, the inner rotating flood control baffle and the outer rotating flood control baffle are both extended up and down, and the flood control isolation airbag fills the space between the inner rotating flood control baffle, the outer rotating flood control baffle and the two side walls of the door.

[0008] When the flood control device for the power distribution station of this scheme is not in use, the flood control isolation airbag bag and the auxiliary support airbag bag are in a contracted state, and the inner rotating flood control baffle and the outer rotating flood control baffle are both in a flat state, which will not affect the daily inspection and maintenance work of the staff and the entry and exit of the equipment in and out of the power distribution station. When the flood season arrives, the air pump inflates the flood control isolation airbag bag and the auxiliary support airbag bag through the air supply pipeline to expand the flood control isolation airbag bag and the auxiliary support airbag bag. During this process, the auxiliary support airbag bag will push the inner rotating flood control baffle to rotate upward around the second rotating axis, and the inner rotating flood control baffle will push the outer rotating flood control baffle to rotate upward around the first rotating axis, so that the flood control isolation airbag can be smoothly inflated between the inner rotating flood control baffle and the outer rotating flood control baffle; the flood control isolation airbag bag will be inflated between the inner rotating flood control baffle and the outer rotating flood control baffle. When the flood-proof isolation airbag is inflated, the connecting rope is in a straight state, the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both extended up and down, and the flood-proof isolation airbag fills the space between the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the two side walls of the door, thereby setting a sealed isolation formed by the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the flood-proof isolation airbag at the bottom of the door; it is easy to operate and effectively prevents rainwater from entering the power distribution station. At the same time, the inflated auxiliary support airbag can support the inner rotating flood-proof baffle on the inner side of the inner rotating flood-proof baffle to prevent it from being crushed by the water outside the power distribution station.

[0009] Preferably, the air supply pipeline includes a first pipeline connecting the air pump and the auxiliary support airbag bag and a second pipeline connecting the auxiliary support airbag bag and the flood control isolation airbag bag. In this way, when the air pump is working, it will first inflate the auxiliary support airbag bag through the first pipeline, so that the auxiliary support airbag bag is inflated and expanded first, and then inflate the flood control isolation airbag bag through the second pipeline. In this way, the auxiliary support airbag bag can first push the inner rotating flood control baffle to rotate upward around the second rotating axis, so that the inner rotating flood control baffle will push the outer rotating flood control baffle to rotate upward around the first rotating axis. Thereafter, the flood control isolation airbag bag is inflated again, so that the flood control isolation airbag can be smoothly inflated and expanded between the inner rotating flood control baffle and the outer rotating flood control baffle.

[0010] Preferably, the second pipeline is provided with an electromagnetic switch valve or a pressure switch valve, and when the air pressure in the auxiliary support airbag bag is greater than the set value, the electromagnetic switch valve or the pressure switch valve is opened. In this way, when the air pump is working, the auxiliary support airbag bag can be inflated first, and when the air pressure in the auxiliary support airbag bag is greater than the set value, the flood control isolation airbag bag is inflated through the second pipeline. In this way, it can be ensured that the auxiliary support airbag bag is inflated first, pushing the inner rotating flood control baffle to rotate upward around the second rotating shaft, so that the inner rotating flood control baffle will push the outer rotating flood control baffle to rotate upward around the first rotating shaft to the right position, and then the flood control isolation airbag bag is inflated again, so that the flood control isolation airbag can be smoothly inflated between the inner rotating flood control baffle and the outer rotating flood control baffle.

[0011] Preferably, an outer baffle plate receiving groove is provided on the ground of the access door of the power distribution station, and the outer baffle plate receiving groove is used to receive the outer rotating flood-proof baffle, the first rotating shaft is located in the outer baffle plate receiving groove, an inner baffle plate receiving groove is provided on the bottom surface of the outer baffle plate receiving groove, and the second rotating shaft is located in the inner baffle plate receiving groove; when the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a lying state, the inner rotating flood-proof baffle is located in the inner baffle plate receiving groove, and the outer rotating flood-proof baffle is located in the outer baffle plate receiving groove. In this way, when the anti-waterlogging device of the power distribution station is not used at ordinary times, and the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a lying state, the inner rotating flood-proof baffle is located in the inner baffle plate receiving groove, and the outer rotating flood-proof baffle is located in the outer baffle plate receiving groove, thereby further ensuring that it will not affect the daily inspection and maintenance work of the staff and the transportation of equipment in and out of the access door of the power distribution station.

[0012] Preferably, the flood control isolation airbag bag accommodating groove is arranged on the bottom surface of the outer baffle plate accommodating groove, and the auxiliary support airbag bag accommodating groove is arranged on the bottom surface of the inner baffle plate accommodating groove.

[0013] Preferably, the first rotating shaft is located on one side of the outer rotating flood-proof baffle, and the second rotating shaft is located on one side of the inner rotating flood-proof baffle. When the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a lying state, the other side of the outer rotating flood-proof baffle opposite to the first rotating shaft is located on the inner side of the inner door frame of the entrance and exit door, and the other side of the inner rotating flood-proof baffle opposite to the second rotating shaft is also located on the inner side of the inner door frame of the entrance and exit door. Since the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both tilted and laid flat toward the inside of the power distribution station, and the other side of the outer rotating flood-proof baffle opposite to the first rotating shaft is located on the inner side of the inner door frame of the door, and the other side of the inner rotating flood-proof baffle opposite to the second rotating shaft is also located on the inner side of the inner door frame of the door, when the air pump works, the flood-proof isolation airbag bag and the auxiliary support airbag bag are inflated, and the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are rotated upward and extended upward and downward, the height of the inner rotating flood-proof baffle and the outer rotating flood-proof baffle can be effectively increased, thereby effectively increasing the height of the sealed isolation formed by the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the flood-proof isolation airbag, which is conducive to preventing rainwater with higher water levels from entering the power distribution station. On the other hand, when the anti-flooding device in the power distribution station is not used at ordinary times, it will not affect the daily inspection and maintenance work of the staff and the transportation of equipment in and out of the power distribution station.

[0014] Preferably, a limit block is provided on the outer door frame of the door, and when the outer rotating flood-proof baffle rotates upward around the first rotating shaft and abuts against the limit block, the outer rotating flood-proof baffle is in a vertical state. In this way, the limit block is used to limit the rotation angle of the outer rotating flood-proof baffle, thereby improving the stability of the sealed isolation formed by the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the flood-proof isolation airbag after the flood-proof isolation airbag bag and the auxiliary support airbag bag are inflated.

[0015] As a preferred method, a water level monitoring device is also included, which includes a first water level sensor arranged at the bottom of the access door of the power distribution station. When the water level outside the power distribution station reaches the first water level sensor, the air pump starts to work and inflate the flood control isolation airbag bag and the auxiliary support airbag bag through the air supply pipeline. In this way, after the water level outside the power distribution station reaches the set position, the air pump can be rotated to expand the flood control isolation airbag bag and the auxiliary support airbag bag, and a sealed isolation formed by the inner rotating flood control baffle, the outer rotating flood control baffle and the flood control isolation airbag is set at the bottom of the access door to effectively prevent rainwater from entering the power distribution station.

[0016] As a preference, it also includes a power-off mechanism for a distribution station house, which is used to control the power on and off of the electrical equipment in the distribution station house. The water level monitoring device includes a second water level sensor arranged outside the access door of the distribution station house, and the second water level sensor is higher than the first water level sensor. When the water level outside the distribution station house reaches the second water level sensor, the power-off mechanism for the distribution station house controls the power off of the electrical equipment in the distribution station house. In this way, after the water level outside the distribution station house reaches the set height, the power off mechanism for the distribution station house can be used to control the power off of the electrical equipment in the distribution station house, thereby avoiding damage to the equipment caused by a short circuit due to water ingress.

[0017] Preferably, one end of the connecting rope is connected to one side of the outer rotating flood-proof baffle, and the other end of the connecting rope is connected to one side of the inner rotating flood-proof baffle, and one end of the connecting rope and the first rotating shaft are located on opposite sides of the outer rotating flood-proof baffle, and the other end of the connecting rope and the second rotating shaft are located on opposite sides of the inner rotating flood-proof baffle.

[0038] Specific embodiment 1: Figure 1 , Figure 2 As shown, a flood prevention device for a power distribution station includes an air pump, an outer rotating flood prevention baffle 3 arranged at the bottom of an access door 1 of the power distribution station by rotating through a first rotating shaft 2, an inner rotating flood prevention baffle 5 arranged at the bottom of the access door of the power distribution station by rotating through a second rotating shaft 4, a connecting rope 6 connecting the outer rotating flood prevention baffle and the inner rotating flood prevention baffle, a flood prevention isolation air bag bag receiving groove 7 and an auxiliary support air bag bag receiving groove 8 arranged on the ground of the access door of the power distribution station, a flood prevention isolation air bag bag 9 arranged in the flood prevention isolation air bag bag receiving groove, and an auxiliary support air bag bag 10 arranged in the auxiliary support air bag bag receiving groove. The first rotating shaft and the second rotating shaft are located between the inner and outer door frames of the access door, and the first rotating shaft is close to the outer door frame of the access door, and the second rotating shaft is close to the inner door frame of the access door. The outer rotating flood prevention baffle is parallel to the first rotating shaft, and the inner rotating flood prevention baffle is parallel to the second rotating shaft. The first rotating shaft is parallel to the second rotating shaft, and the first rotating shaft is parallel to the width direction of the access door. The width of the outer rotating flood-proof baffle and the inner rotating flood-proof baffle are both smaller than the width of the door. In this embodiment, the width of the outer rotating flood-proof baffle and the inner rotating flood-proof baffle are the same, and the difference between the width of the door and the outer rotating flood-proof baffle is 1-5 cm. The flood-proof isolation airbag bag and the auxiliary support airbag bag are both rubber airbag bags.

[0039] The flood control isolation airbag bag receiving slot is located between the first rotating shaft and the second rotating shaft. The auxiliary support airbag bag receiving slot and the flood control isolation airbag bag receiving slot are located on both sides of the second rotating shaft, and the air pump is connected to the flood control isolation airbag bag and the auxiliary support airbag bag through an air supply pipeline. In this embodiment, the slot width of the flood control isolation airbag bag receiving slot is the same as the width of the entrance door, and the auxiliary support airbag bag receiving slot is located in the power distribution station room.

[0040] When the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a flat state, the inner rotating flood-proof baffle is located below the outer rotating flood-proof baffle, and the inner rotating flood-proof baffle blocks the notch of the auxiliary support airbag bag receiving slot, and the outer rotating flood-proof baffle blocks the notch of the flood-proof isolation airbag bag receiving slot. In this embodiment, the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both tilted and laid flat toward the power distribution station room, and when the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a flat state, the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a horizontal state.

[0041] When the air pump inflates the flood control isolation airbag bag and the auxiliary support airbag bag through the air supply pipeline, causing the flood control isolation airbag bag and the auxiliary support airbag bag to expand, the auxiliary support airbag bag will push the inner rotating flood control baffle to rotate upward around the second rotating axis, and the inner rotating flood control baffle will push the outer rotating flood control baffle to rotate upward around the first rotating axis; the flood control isolation airbag bag will be inflated between the inner rotating flood control baffle and the outer rotating flood control baffle.

[0042] like Figure 3 As shown, when the flood-proof isolation airbag is inflated, the connecting rope is in a stretched state, the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both extended up and down, and the flood-proof isolation airbag fills the space between the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the two side walls of the door; thereby, a sealed isolation formed by the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the flood-proof isolation airbag is set at the bottom of the door.

[0043] In this embodiment, the door frame of the access door of the distribution station room includes an outer door frame located on the outer side wall of the wall where the access door is located, an inner door frame located on the inner side wall of the wall where the access door is located, and a door frame plate connecting the inner and outer door frames.

[0044] When the flood control device for the power distribution station of this embodiment is not in use, the flood control isolation airbag bag and the auxiliary support airbag bag are in a contracted state, and the inner rotating flood control baffle and the outer rotating flood control baffle are both in a flat state, which will not affect the daily inspection and maintenance work of the staff and the entry and exit of the equipment in and out of the power distribution station. When the flood season comes, the air pump inflates the flood control isolation airbag bag and the auxiliary support airbag bag through the air supply pipeline to expand the flood control isolation airbag bag and the auxiliary support airbag bag. During this process, the auxiliary support airbag bag will push the inner rotating flood control baffle to rotate upward around the second rotating axis, and the inner rotating flood control baffle will push the outer rotating flood control baffle to rotate upward around the first rotating axis, so that the flood control isolation airbag can be smoothly inflated between the inner rotating flood control baffle and the outer rotating flood control baffle; the flood control isolation airbag bag will be inflated between the inner rotating flood control baffle and the outer rotating flood control baffle. When the flood-proof isolation airbag is inflated, the connecting rope is in a straight state, the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both extended up and down, and the flood-proof isolation airbag fills the space between the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the two side walls of the door, thereby setting a sealed isolation formed by the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the flood-proof isolation airbag at the bottom of the door; it is easy to operate and effectively prevents rainwater from entering the power distribution station. At the same time, the inflated auxiliary support airbag can support the inner rotating flood-proof baffle on the inner side of the inner rotating flood-proof baffle to prevent it from being crushed by the water outside the power distribution station.

[0045] Specifically, one end of the connecting rope 6 is connected to one side of the outer rotating flood-proof baffle, and the other end of the connecting rope is connected to one side of the inner rotating flood-proof baffle, and one end of the connecting rope and the first rotating shaft are located on opposite sides of the outer rotating flood-proof baffle, and the other end of the connecting rope and the second rotating shaft are located on opposite sides of the inner rotating flood-proof baffle. In this embodiment, there are multiple connecting ropes, and the multiple connecting ropes are sequentially distributed along the axial direction of the first rotating shaft.

[0046] Further, such as Figure 1 As shown, the flood prevention device of the power distribution station also includes a water level monitoring device. The water level monitoring device includes a first water level sensor 11 arranged at the bottom of the access door of the power distribution station. When the water level outside the power distribution station reaches the first water level sensor, the air pump works to inflate the flood control isolation airbag bag and the auxiliary support airbag bag through the air supply pipeline. In this way, after the water level outside the power distribution station reaches the set position, the air pump can be rotated to expand the flood control isolation airbag bag and the auxiliary support airbag bag, and a sealed isolation formed by an inner rotating flood control baffle, an outer rotating flood control baffle and a flood control isolation airbag is set at the bottom of the access door to effectively prevent rainwater from entering the power distribution station.

[0047] Further, such as Figure 1As shown, the power distribution station building flood prevention device also includes a power-off mechanism for the power distribution station building. The power-off mechanism for the power distribution station building is used to control the power on and off of the electrical equipment in the power distribution station building. The water level monitoring device includes a second water level sensor 12 arranged on the outside of the access door of the power distribution station building, and the second water level sensor is higher than the first water level sensor. When the water level outside the power distribution station building reaches the second water level sensor, the power-off mechanism for the power distribution station building controls the power supply of the electrical equipment in the power distribution station building to be disconnected. In this way, after the water level outside the power distribution station building reaches the set height, the power-off mechanism for the power distribution station building can be used to control the power supply of the electrical equipment in the power distribution station building to be disconnected, thereby avoiding damage to the equipment caused by a short circuit due to water ingress.

[0048] Further, such as Figure 1 , Figure 3 As shown, a stop block 1.1 is provided on the outer door frame of the door, and when the outer rotating flood-proof baffle rotates upward around the first rotation axis and abuts against the stop block, the outer rotating flood-proof baffle is in a vertical state. In this way, the stop block is used to limit the rotation angle of the outer rotating flood-proof baffle, thereby improving the stability of the sealed isolation formed by the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the flood-proof isolation airbag after the flood-proof isolation airbag bag and the auxiliary support airbag bag are inflated.

[0049] Furthermore, the air supply pipeline includes a first pipeline connecting the air pump and the auxiliary support airbag bag and a second pipeline connecting the auxiliary support airbag bag and the flood control isolation airbag bag. In this way, when the air pump is working, it will first inflate the auxiliary support airbag bag through the first pipeline, so that the auxiliary support airbag bag is inflated and expanded first, and then inflate the flood control isolation airbag bag through the second pipeline. In this way, the auxiliary support airbag bag can first push the inner rotating flood control baffle to rotate upward around the second rotating axis, so that the inner rotating flood control baffle will push the outer rotating flood control baffle to rotate upward around the first rotating axis. Thereafter, the flood control isolation airbag bag is inflated again, so that the flood control isolation airbag can be smoothly inflated and expanded between the inner rotating flood control baffle and the outer rotating flood control baffle.

[0050] The second pipeline is provided with an electromagnetic switch valve or a pressure switch valve, and when the air pressure in the auxiliary support airbag bag is greater than the set value, the electromagnetic switch valve or the pressure switch valve is opened. In this way, when the air pump is working, the auxiliary support airbag bag can be inflated first, and when the air pressure in the auxiliary support airbag bag is greater than the set value, the flood control isolation airbag bag is inflated through the second pipeline. In this way, it can be ensured that the auxiliary support airbag bag is inflated first, and the inner rotating flood control baffle is pushed to rotate upward around the second rotating shaft, so that the inner rotating flood control baffle will push the outer rotating flood control baffle to rotate upward around the first rotating shaft to the right position, and then the flood control isolation airbag bag is inflated again, so that the flood control isolation airbag can be smoothly inflated between the inner rotating flood control baffle and the outer rotating flood control baffle.

[0051] Further, such as Figure 1 , Figure 2As shown, an outer baffle plate receiving groove 13 is provided on the ground of the access door of the power distribution station, and the outer baffle plate receiving groove is used to receive the outer rotating flood-proof baffle. The first rotating shaft is located in the outer baffle plate receiving groove. An inner baffle plate receiving groove 14 is provided on the bottom surface of the outer baffle plate receiving groove. The second rotating shaft is located in the inner baffle plate receiving groove. When the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a flat state, the inner rotating flood-proof baffle is located in the inner baffle plate receiving groove, and the outer rotating flood-proof baffle is located in the outer baffle plate receiving groove. The flood-proof isolation airbag bag receiving groove is provided on the bottom surface of the outer baffle plate receiving groove, and the auxiliary support airbag bag receiving groove is provided on the bottom surface of the inner baffle plate receiving groove. In this embodiment, when the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a flat state, the outer rotating flood-proof baffle is in a horizontal state, and the upper surface of the outer rotating flood-proof baffle is flush with the ground of the access door of the power distribution station. In this way, when the anti-flooding device of the distribution station is not in use, the inner rotating flood baffle and the outer rotating flood baffle are in a lying state, the inner rotating flood baffle is located in the inner baffle accommodating groove, and the outer rotating flood baffle is located in the outer baffle accommodating groove, thereby further ensuring that it will not affect the staff's daily patrol and operation and maintenance work and the entry and exit of equipment in and out of the distribution station.

[0052] Further, such as Figure 1 As shown, the first rotating shaft is located on one side of the outer rotating flood-proof baffle, and the second rotating shaft is located on one side of the inner rotating flood-proof baffle. When the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both in a lying state, the other side of the outer rotating flood-proof baffle opposite to the first rotating shaft is located on the inner side of the inner door frame of the entrance and exit door, and the other side of the inner rotating flood-proof baffle opposite to the second rotating shaft is also located on the inner side of the inner door frame of the entrance and exit door. Since the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are both tilted and laid flat toward the inside of the power distribution station, and the other side of the outer rotating flood-proof baffle opposite to the first rotating shaft is located on the inner side of the inner door frame of the door, and the other side of the inner rotating flood-proof baffle opposite to the second rotating shaft is also located on the inner side of the inner door frame of the door, when the air pump works, the flood-proof isolation airbag bag and the auxiliary support airbag bag are inflated, and the inner rotating flood-proof baffle and the outer rotating flood-proof baffle are rotated upward and extended upward and downward, the height of the inner rotating flood-proof baffle and the outer rotating flood-proof baffle can be effectively increased, thereby effectively increasing the height of the sealed isolation formed by the inner rotating flood-proof baffle, the outer rotating flood-proof baffle and the flood-proof isolation airbag, which is conducive to preventing rainwater with higher water levels from entering the power distribution station. On the other hand, when the anti-flooding device in the power distribution station is not used at ordinary times, it will not affect the daily inspection and maintenance work of the staff and the transportation of equipment in and out of the power distribution station.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
