The beveled surfaces can increase the contact area and at the same time can more effectively transmit force to make it move, making it more convenient to use.

[0033] The lever mechanism includes a lever plate 61, which is rotatably mounted on the ground of the distribution station building 1. The lever plate 61 contacts the bottom of the limit frame 8. A floating block 62 is fixedly mounted on the end of the bottom of the lever plate 61 away from the limit frame 8. A limiting block 64 is fixedly mounted on the end of the lever plate 61 close to the limit frame 8. A lever 63 is fixedly mounted on the bottom of the lever plate 61. Both ends of the lever 63 are rotatably mounted on the ground of the distribution station building 1. The lever 63 is fixedly mounted on one side of the bottom of the lever plate 61 close to the flood prevention mechanism. The floating block 62 will float up and down under the action of the water level. When the water level exceeds the limit, the floating block 62 will float up.

The movement of the floating block 62 will drive the lever plate 61 to rotate on one side close to the distribution machine 7, and at the same time, the other side will rotate in the opposite direction under the action of the lever principle.

[0034] The lever plate 61 is rotatably connected to the T-shaped guide rod 85, and a chamfered surface is provided at one end of the bottom of the limit block 2 64 close to the limit block 6 810, and the chamfered surface at the bottom of the limit block 2 64 contacts the chamfered surface of the limit block 6 810, and the limit block 2 64 moves downward to squeeze the limit block 6 810 to move to the side away from the limit block 2 64 to release the limit on the limit block 3 86.

[0035] The gas storage mechanism is fixedly installed on the ground of the power distribution station room 1, and the gas storage mechanism includes a gas storage tank 44, which is fixedly installed on the ground of the power distribution station room 1, and the gas storage tank 44 is fixedly installed with a gas pipe 1 48, and the gas pipe 1 48 is fixedly installed on the surface of the gas valve 41, and a gas valve switch 45 is rotatably installed on the surface of the gas valve 41, and a gas pipe 2 42 is fixedly installed on the surface of the gas valve 41, and a card groove 2 49 is provided on the inner wall of the power distribution station room 1, and a limit block 1 43 is slidably installed inside the card groove 2 49, and the gas pipe 2 42 is connected with the rubber bag 47, and a chamfer is provided on the end of the limit block 1 43 close to the guide rod 811, and the upper part of the limit block 1 43 is connected with the card groove 2 49 The rubber bag 47 is connected by a spring, and a pressure relief valve is installed inside the rubber bag 47. The rubber bag 47 is connected to the jet pipe 46. The cylinder 44 is filled with carbon dioxide. The valve switch 45 will be opened during the rising process of the T-shaped baffle 82, so that the carbon dioxide inside the gas tank 44 will inflate the rubber bag 47. The rubber bag 47 is inflated to fill the gap between the limit frame 8 and the door 2, thereby improving the sealing performance of the flood prevention mechanism and preventing water from further penetrating into the interior of the distribution station building 1. At the same time, excess carbon dioxide will be discharged into the interior of the distribution station building 1 through the jet pipe 46, thereby reducing the oxygen content inside, avoiding short circuit of the distribution machine 7, and reducing the risk of fire caused by the distribution machine 7.

[0036] A switch 9 is fixedly installed on the inner wall of the distribution station building 1, and a water pump 5 is fixedly installed on the ground inside the distribution station building 1. The switch 9 is electrically connected to the water pump 5. When the T-shaped guide rod 85 moves to open the switch 9, the water pump 5 will extract the accumulated water in the water collection tank 3 inside the distribution station building 1 and discharge it outward, thereby reducing the accumulated water inside the distribution station building 1, avoiding short-circuit corrosion of the distribution machine 7 due to excessive humidity inside the station building, increasing the service life of the distribution machine 7, and reducing maintenance costs.

[0037] During operation, when the water level outside rises, water enters the water collection tank 3 inside the power distribution station room 1 through the gap of the door 2. When the water level in the water collection tank 3 inside the power distribution station room 1 rises, the rising water level causes the floating block 62 to float up. The floating block 62 pushes the lever plate 61 close to the power distribution machine 7 to rotate upward. The lever plate 61 rotates upward to drive the lever 63 to rotate. The lever 63 rotates to drive the lever plate 61 at the other end of the lever 63 to rotate downward. The lever plate 61 rotates downward to drive the limit block 2 64 to move downward. The limit block 64 moves downward. The chamfered surface of the second block 64 contacts the chamfered surface of the sixth limit block 810, and the second limit block 64 moves downward to squeeze the sixth limit block 810 to move to the side away from the second limit block 64, and the sixth limit block 810 moves to release the limit on the third limit block 86. After the limit is released, the T-shaped baffle plate 82 moves upward under the action of the tension spring 81, and the upward movement of the T-shaped baffle plate 82 can improve the sealing effect between the door 2 and the power distribution station room 1, so as to prevent water from entering the interior of the power distribution station room 1 from the position of the door 2;

[0038] At the same time, the lever plate 61 rotates downward to drive the T-shaped guide rod 85 to move downward, and the T-shaped guide rod 85 moves downward and contacts and limits the beveled surface of the limit block 5 88, and the contact causes the limit block 5 88 to move to the side away from the T-shaped guide rod 85, and the limit block 5 88 is connected to the limit block 4 87 through a spring, and the limit block 5 88 moves to squeeze the spring to move the limit block 4 87 to the side away from the spring, and the limit block 4 87 moves to limit the T-shaped baffle 82, so that the T-shaped baffle 82 cannot be pressed down to reset, and it can also play a blocking role when the door 2 is opened, avoiding improper operation to open the waterlogging prevention mechanism when there is water outside the distribution station room 1, thereby causing damage to the distribution machine 7;

[0039] The T-shaped guide rod 85 moves downward, driving the guide rod 811 to move downward. The guide rod 811 moves downward to squeeze the limit block 43 to move to the side away from the guide rod 811. After the limit block 43 moves to release the limit, it moves downward under the action of the spring. The limit block 43 moves downward to drive the gas valve switch 45 to rotate. The gas valve switch 45 rotates to open the gas valve 41 for ventilation. The gas valve 41 opens to allow the carbon dioxide inside the gas storage tank 44 to enter the rubber bag 47 through the gas pipe 1 48 and the gas pipe 2 42, so that the rubber bag 47 expands. The rubber bag 47 is inflated to fill the gap between the limit frame 8 and the door 2, thereby improving the sealing performance of the flood prevention mechanism and preventing water from further penetrating into the distribution station room 1.

[0040] A pressure relief valve is arranged inside the rubber bag 47. When the rubber bag 47 is full, the carbon dioxide is sprayed toward the power distribution machine 7 through the air jet pipe 46 through the pressure relief valve, thereby reducing the oxygen content inside the power distribution station 1, avoiding a short circuit in the power distribution machine 7, and reducing the risk of fire in the power distribution machine 7. The T-shaped guide rod 85 moves downward to contact and open the switch 9, which is electrically connected to the water pump 5. When the switch 9 is turned on, the water pump 5 starts to work and discharges the accumulated water inside the water collection tank 3 to the outside, thereby reducing the accumulated water inside the power distribution station 1, increasing the service life of the power distribution machine 7, and reducing the maintenance cost.

[0041] When the water level in the sump 3 inside the distribution station building 1 drops, the drop in water level causes the floating block 62 to sink, and the sinking of the floating block 62 drives the lever plate 61 to rotate downward, and the downward rotation of the lever plate 61 drives the lever 63 to rotate, and the rotation of the lever 63 drives the lever plate 61 at the other end of the lever 63 to rotate upward, and the upward rotation of the lever plate 61 pushes the T-shaped guide rod 85 to move upward, and the T-shaped guide rod 85 moves upward to contact the limit of the limit block five 88, and the limit block five 88 releases the limit and moves to the side close to the T-shaped guide rod 85, and the limit block five 88 moves through the spring to drive the limit block four 87 to move to the side close to the spring, and the limit block four 87 moves to release the limit on the T-shaped baffle 82, so that the maintenance personnel can reset the T-shaped baffle 82 by pressing down to perform equipment maintenance.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
