Description

Technical Field

[0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to a multifunctional high and low voltage switch power distribution cabinet. Background Art

[0002] High and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. For example, a centrally mounted high and low voltage switch distribution cabinet is proposed in patent announcement number CN109494586A.

[0003] After long-term use, the rubber strip inside the cabinet door will lose its original sealing performance due to aging and other problems. External dust and other impurities will penetrate into the cabinet through the gaps, which not only greatly increases the risk of short circuit inside the cabinet, but also reduces its heat dissipation efficiency. In addition, the distribution cabinets used outdoors will generate heat due to the operation of the equipment inside the distribution cabinet, causing the internal temperature to be higher than the external temperature. When the distribution cabinet is set near a landfill, animals such as rats in the landfill like warm environments, especially in cold seasons, and will look for heat sources to keep warm. Once the rats set their sights on a heat source, they will bite the dust net of the distribution cabinet, and then break into the interior and gnaw on the lines inside the distribution cabinet, seriously affecting the normal operation of the distribution cabinet.

[0021] The filtering assembly 30 is arranged at the air inlet end of the high-pressure air pump 7 and is used for filtering gas. The filtering assembly 30 includes an installation cover 301 fixedly connected and communicated with the air inlet end of the high-pressure air pump 7. A cylinder 302 is placed below the installation cover 301. The cylinder 302 and the installation cover 301 are connected by bolts.

[0022] A sewage discharge pipe 38 is fixedly connected to the side wall of the collection cover 201. A sewage discharge valve 39 is arranged in the sewage discharge pipe 38, which can discharge the impurities inside the collection cover 201. An air discharge pipe 43 is fixedly connected to the side wall of the lifting cavity 401. An opening and closing valve 44 is arranged in the air discharge pipe 43, which can discharge the gas inside the lifting cavity 401.

[0023] The operating principle of the present invention is described as follows: When the operator finishes the maintenance of the high and low voltage switch distribution cabinet and closes the cabinet door 2, the controller 4 will first control the high-pressure air pump 7 to work and control the blocking valve 46 to open (other valves are in the closed state). The high-pressure air pump 7 conveys the externally filtered gas to the lifting cavity 401 through the elbow 45, increasing the air pressure above the piston plate 402. Under the action of the air pressure, the piston plate 402 will drive the sealing plate 41 to move downward, causing the sealing plate 41 to extend out of the lifting cavity 401 and insert into the sealing groove 42 (structures such as sealing gaskets are provided in the sealing groove 42 to ensure the sealing performance of the sealing plate 41), thus blocking the heat dissipation port 5 and making the cabinet body 1 in a sealed state. Then, the controller 4 controls the blocking valve 46 to close and controls the first control valve 9 to open. The high-pressure air pump 7 will convey external gas into the cabinet body 1, increasing the internal air pressure of the cabinet body 1. After the air pressure sensor 10 detects that the internal air pressure of the cabinet body 1 reaches the set threshold value (1.5 standard atmospheric pressures), the air pressure sensor 10 will control the high-pressure air pump 7 to stop working and control the first control valve 9 to close through the controller 4, keeping the internal of the cabinet body 1 in a high-pressure state for 30 minutes. When the air pressure sensor 10 detects a decrease in the internal air pressure of the cabinet body 1 within 30 minutes, it indicates that the rubber sealing strip 3 has lost its sealing performance due to aging or other reasons. The air pressure sensor 10 will send this information to the operator through the wireless communication module inside the controller 4, reminding the operator to replace the rubber sealing strip 3 in time, thus ensuring the sealing performance of the cabinet body 1. Subsequently, the controller 4 will control the opening and closing valve 44 to open, discharging the gas inside the lifting cavity 401 through the discharge pipe 43. Under the action of the upward spring tension above, the piston plate 402 will move upward into the lifting cavity 401, discharging the gas inside the cabinet body 1; When animals such as rats outdoors bite through the dust-proof net 6 and enter the cabinet body 1, the rat will first pass through multiple blocking rods 14. The blocking rods 14 will drive the connecting sleeve 13 and the conductive block 16 to rotate together. During the rotation of the conductive block 16, it will contact the arc-shaped conductive plate 17. The conductive block 16 is electrically connected to an external power source, and the arc-shaped conductive plate 17 is electrically connected to the controller 4. When the conductive block 16 contacts the arc-shaped conductive plate 17, an electrical signal will be sent to the controller 4. After receiving this electrical signal, the controller 4 will control the electric shock plate 19 to be electrically connected to the external power source, making the electric shock plate 19 charged (the current is less than 15 mA and will not electrocute the rat to death), and will control the electromagnetic block 37 to lose its magnetic force for one minute. Since the rat will fall into the guiding cylinder 18 after passing through the blocking rods 14 and will be above the electric shock plate 19, the electric shock plate 19 will make the rat feel pain and look for an exit everywhere. When the rat pushes open the magnetic baffle 36, it will leave the cabinet body 1 through the discharge port 35, thus avoiding the problem of rats biting the wires; When the power distribution cabinet is used outdoors and it is raining outdoors, the rainwater is collected by the collection cover 201. And within the initial twenty minutes, the sewage pipe 38 is in an open state. Dust and other impurities inside the collection cover 201 will be discharged through the sewage pipe 38 under the flushing of the rainwater. After the rain sensor (not shown in the figure) outside the cabinet 1 detects that it has been raining for twenty minutes, the rain sensor will control the sewage valve 39 to close through the controller 4 and control the second control valve 22 to open. Then the rainwater will be conveyed into the water tank 202 through the water inlet pipe 21. After the liquid level sensor (not shown in the figure) inside the water tank 202 detects that the liquid in the water tank 202 reaches the set position, the liquid level sensor will control the second control valve 22 to close through the controller 4 and control the high-pressure air pump 7 to work. At the same time, the third control valve 24 and the fourth control valve 26 are controlled to open, so that the rainwater pressurized by the gas is conveyed to the water delivery cavity 28 through the vertical pipe 25 and the horizontal pipe 27 and sprayed out through the spray holes 29 inclined towards the dust-proof net 6 to wash the impurities on the surface of the dust-proof net 6, thus ensuring the permeability of the dust-proof net 6.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
