[0002] In the power system of a substation, a switch cabinet, as one of the core devices, undertakes important functions such as power distribution, control and protection.

[0036] As an embodiment of the present application, the inner top space of the hollow column 25 is communicated with the outside through the second exhaust pipe 26, the whistle 27 and the first electromagnetic valve 28 are installed on the second exhaust pipe 26, the hollow strip 20 is installed on the rear wall of the cabinet 1, the air outlet 21 is formed on the front wall of the hollow strip 20, the inner top space of the hollow column 25 is communicated with the hollow strip 20 through the first exhaust pipe 22, the second electromagnetic valve 29 and the third electromagnetic valve 30 are installed on the first exhaust pipe 22, the temperature sensor 12 cooperates with the first electromagnetic valve 28 and the second electromagnetic valve 29, when the internal temperature rises to be higher than the set temperature, the processor will control the driving motor 7 to be closed for a period of time, and the first electromagnetic valve 28 and the second electromagnetic valve 29 are opened for a period of time, the first electromagnetic valve 28 is opened, the second exhaust pipe 26 releases gas, the whistle 27 alarms to remind the surrounding people to start cleaning operation, a plurality of groups of conductive parts are sequentially arranged on the inner wall of the hollow column 25 from top to bottom, each group of conductive parts is composed of two power connection blocks 39 embedded on the inner wall of the hollow column 25, the second piston plate 41 has conductivity, and the plurality of groups of conductive parts cooperate with the third electromagnetic valve 30, that is, the third electromagnetic valve 30 is electrified after each time the conductive part is electrified, when the third electromagnetic valve 30 and the second electromagnetic valve 29 are both electrified, the first exhaust pipe 22 releases gas, in this way, the first exhaust pipe 22 releases gas intermittently, and during the heat dissipation process, due to the continuous right-to-left gas flow generated at the plurality of ventilation grooves 3, the filter screen 4 moves rightward and compresses the first spring 42, when the subsequent heat dissipation mechanism stops running, the filter screen 4 is shaken multiple times under the elastic action of the first spring 42 and the inertial action of the filter screen 4, and finally stops moving, the shaking can make the accumulated dust fall off, when the two first piston plates 18 reciprocate left and right, a plurality of one-way valves can be used to generate continuous one-way gas flow in the cabinet 1, the piston cylinder 43, the main pipeline 24 and the hollow column 25, the one-way gas flows out of the cabinet 1, the cabinet 1 replenishes gas from the filter screen 4, so as to achieve the purpose of gas flow heat dissipation, and the gas finally enters the hollow column 25 and accumulates at the top of the hollow column 25, so as to drive the second piston plate 41 to move downward, so that the second spring 38 is compressed, when the second piston plate 41 moves to below the discharge hole 37, the gas is discharged from the discharge hole 37, so that the second piston plate 41 is maintained at this position, facilitating subsequent release.

[0037] In the application, the driving motor 7 is started, and the output shaft drives the incomplete gear 16 to rotate. The incomplete gear 16 intermittently engages with the racks 15 on the top and bottom of the frame 14, so that the frame 14 reciprocates left and right under the cooperation of the guide bars 23 and the guide grooves. The connecting rods 17 on both sides of the frame 14 drive the first piston plate 18 to slide left and right in the piston cylinder 43. When the first piston plate 18 slides to the left, the space on the opposite side of the piston cylinder 43 draws air from the inside of the cabinet 1 through the one-way channel 13; when the first piston plate 18 slides to the right, the gas in the space on the opposite side of the piston cylinder 43 is discharged into the main pipeline 24 through the one-way pipe 8, and then into the top space of the hollow column 25. In this way, a continuous one-way airflow is generated in the cabinet 1, the piston cylinder 43, the main pipeline 24 and the hollow column 25, the gas in the cabinet 1 is drawn away, and the cabinet 1 replenishes the gas from the filter screen 4 at the ventilation slot 3, realizing the gas flow heat dissipation;

[0038] When the output shaft of the driving motor 7 rotates, it drives the first bevel gear 33 to rotate, and the first bevel gear 33 engages with the second bevel gear 34 to make the rotating shaft 32 rotate. The third bevel gear 35 on the right end of the rotating shaft 32 engages with the fourth bevel gear 36 on the upper end of the reciprocating screw rod 10 to drive the reciprocating screw rod 10 to rotate. The reciprocating screw rod 10 is threadedly connected with the lifting block 11, so that the lifting block 11 drives the temperature sensor 12 to reciprocate up and down in the cabinet 1, thereby expanding the temperature detection range. The temperature sensor 12 transmits the detected temperature signal to the processor for processing;

[0039] During the operation of the heat dissipation mechanism, if the temperature is low, it indicates that part of the filter screen 4 is not blocked; if the temperature continues to rise and eventually exceeds the set value, it indicates that part of the filter screen 4 is in a blocked state. When the internal temperature rises above the set temperature, the processor controls the driving motor 7 to be turned off for a period of time, and the first electromagnetic valve 28 and the second electromagnetic valve 29 are opened. After the first electromagnetic valve 28 is opened, the gas in the top space of the hollow column 25 is released through the second exhaust pipe 26, and the whistle 27 emits an alarm to remind people around to start cleaning operation;

[0040] During the heat dissipation process, continuous left-to-right gas flow is generated at the multiple ventilation slots 3, and the filter screen 4 moves to the right and compresses the first spring 42. When the subsequent heat dissipation mechanism stops running, under the elastic action of the first spring 42 and the inertial action of the filter screen 4, the filter screen 4 is shaken multiple times to shake off the accumulated dust. During the heat dissipation process, after the gas enters the top space of the hollow column 25, it pushes the second piston plate 41 to move downward, so that the second spring 38 is compressed. When the second piston plate 41 moves to below the discharge hole 37, the gas will be discharged from the discharge hole 37, so that the second piston plate 41 is maintained at this position;

[0041] In the second exhaust pipe 26 continues to exhaust process (i.e. cleaning process), the second piston plate 41 is constantly moving up, when the second piston plate 41 up with different height of the electrically conductive contact, the electrically conductive member energized, each time the electrically conductive member energized will make the third solenoid valve 30 energized, when the third solenoid valve 30 and the second solenoid valve 29 are energized, the first exhaust pipe 22 release gas, gas through the hollow strip 20 front wall on the air jet 21 jet, let the cabinet 1 inside the gas pressure increases, so that a plurality of ventilation slots 3 from right to left air flow, the gas flow can be backflush cleaning filter screen 4, and will shake off the dust away from the filter screen 4, the first exhaust pipe 22 can be intermittent release of gas, to ensure the cleaning effect, because of the intermittent exhaust, in the exhaust, by the effect of the air flow, let the filter screen 4 left, when not exhaust, in the first spring 42 elastic effect and filter screen 4 inertia effect, the filter screen 4 will be more than once shaking, the whole cleaning process, the filter screen 4 will be more than once in the state of shaking, with the gas backflush, the overall cleaning effect is better;

[0042] It is worth mentioning that, in the above cleaning process, because the first exhaust pipe 22 is intermittent release of gas, so, in the hollow column 25 inside the top gas through the second exhaust pipe 26 release gas is also constantly changing the amount, resulting in the flow rate of the gas is constantly changing, the sound of the whistle 27 is small, the effect is better.

[0043] The above, only for the preferred embodiments of the present application, but the scope of protection of the present application is not limited to this, any skilled in the art of the technical personnel in the technical range of the present application disclosed, according to the technical solution of the present application and the invention concept of equivalent replacement or change, should be covered in the scope of protection of the present application.
