[0004] With respect to the above-mentioned related technologies, the inventors believe that when the vibration device vibrates the dustproof net, the dust on the dustproof net will fly around in the ring network cabinet, and some of the dust will be absorbed by the equipment in the ring network cabinet, which will affect the operation of some more precise equipment. Summary of the invention

[0005] In order to reduce the impact of dust on equipment in a ring main unit, the present application provides a dustproof and heat-dissipating ring main unit.

[0006] In the first aspect, the dust-proof heat dissipation type ring main unit provided in the present application adopts the following technical solution:

[0007] A dustproof and heat-dissipating ring network cabinet comprises a cabinet body, a dustproof net, a vibration device and a dust collecting box, and also comprises a dust barrier. The side wall of the cabinet body is provided with heat dissipation holes. The dustproof net and the vibration device are both installed on the inner wall of the cabinet body. The dustproof net covers the heat dissipation holes. The vibration device abuts against the dustproof net. The dust barrier and the dust collecting box are both installed on the inner wall of the cabinet body. The dust collecting box is located between the dust barrier and the dustproof net. The dust barrier comprises a flexible expansion bag, an air conveying piece and an exhaust piece. The flexible expansion bag and the air conveying piece are both installed on the inner wall of the cabinet body. The exhaust piece is installed on the flexible expansion bag. The air conveying piece and the exhaust piece are both connected to the flexible expansion bag.

[0008] By adopting the above technical solution, when the exhaust component empties the gas in the flexible expansion bag, the flexible expansion bag contracts, and the hot air in the cabinet can pass through the dustproof net and the heat dissipation holes and be discharged outside the cabinet, so that the cabinet can dissipate heat normally. When the air delivery component inflates the flexible expansion bag, the flexible expansion bag expands and isolates the dustproof net from the equipment in the cabinet. When the vibration device vibrates the dustproof net, dust floats between the flexible expansion bag and the dustproof net and finally falls into the dust collection box. The flexible expansion bag can reduce the dust on the dustproof net from falling on the equipment in the cabinet, thereby helping to reduce the impact of dust on the equipment in the cabinet.

[0009] In a specific feasible implementation scheme, the exhaust component includes an air jet pipe, an elastic plug, an exhaust pipe and an exhaust control valve, there are several air jet pipes, the air jet pipe is fixedly connected to the surface of the flexible expansion bag facing the dustproof net, the air jet pipe is communicated with the flexible expansion bag, the elastic plug is arranged in the air jet pipe, one side wall of the elastic plug is fixedly connected to the inner wall of the air jet pipe, the other side wall of the elastic plug abuts against the inner wall of the air jet pipe, the exhaust pipe is fixedly connected to the flexible expansion bag, and the exhaust control valve is installed on the exhaust pipe.

[0010] By adopting the above technical solution, when the pressure in the flexible expansion bag is high, the elastic plug is deformed under the pressure of the air pressure, and the gas in the flexible expansion bag is sprayed on the dustproof net through the air jet pipe, which can not only reduce the damage of the flexible expansion bag due to excessive pressure, but also blow off the dust on the dustproof net, which is helpful for cleaning the dust. When the exhaust control valve is opened, the gas in the flexible expansion bag can be discharged, and when the exhaust control valve is closed, the flexible expansion bag can be expanded.

[0011] In a specific feasible implementation scheme, the gas delivery component includes an air pump, an air delivery pipe and a gas delivery control valve. The air pump is installed on the inner wall of the cabinet, one end of the air delivery pipe is connected to the gas delivery end of the air pump, and the other end of the air delivery pipe is connected to the flexible expansion bag. The air valve is installed on the air delivery pipe.

[0012] By adopting the above technical solution, when the gas supply control valve is opened, the air pump inflates the flexible expansion bag through the gas supply pipe, and when the gas supply control valve is closed, the gas can remain in the flexible expansion bag, so that the flexible expansion bag can maintain an expanded state.

[0013] In a specific feasible implementation scheme, the flexible expansion bag includes a flexible airbag and a rolling strip for rolling up the flexible airbag. There are several flexible airbags, and the flexible airbags are fixedly connected to the inner wall of the cabinet. Several flexible airbags are connected in sequence, and two adjacent flexible airbags are connected. The rolling strip is fixedly connected to the flexible airbag, and the air delivery component and the exhaust component are both connected to the flexible airbag.

[0014] By adopting the above technical solution, a plurality of flexible airbags are used to form a flexible expansion bag, so that the flexible expansion bag is still relatively flat after expansion, and the space between the flexible expansion bag and the dustproof net is large, which is convenient for dust to fall into the dust collection box. The reel is a long strip in the shape of a measuring tape, which is in a spiral winding state under normal conditions. When the flexible airbag is inflated, the reel straightens with the expansion of the flexible airbag, so that the entire flexible expansion bag can form a barrier wall. When the gas in the flexible airbag is discharged, the reel automatically reels and drives the flexible airbag to reel, which is convenient for storing the flexible airbag and reduces the impact on the heat dissipation of the cabinet.

[0015] In a specific possible implementation manner, the flexible expansion bag further comprises a dust sticking film, and the dust sticking film is adhered to the surface of the flexible airbag facing the dustproof net.

[0016] By adopting the above technical solution, the dust-sticking film can adhere to the dust close to the flexible airbag, and when the flexible airbag is rolled up, the problem of dust on the flexible airbag flying again can be reduced.

[0017] In a specific feasible implementation scheme, a plurality of side sealing blocks are provided on the inner wall of the cabinet, the flexible expansion bag is located between two opposite side sealing blocks, a clamping groove is provided on the side wall of the side sealing block facing the flexible expansion bag, the flexible expansion bag is inserted into the clamping groove, and the flexible expansion bag abuts against the groove wall of the clamping groove.

[0018] By adopting the above technical solution, the side sealing block helps to press against the flexible expansion bag in an expanded state, thereby reducing the dust from passing through the gap between the flexible expansion bag and the inner wall of the cabinet.

[0019] In a specific possible implementation manner, a blocking rod is installed on the inner wall of the cabinet, and the blocking rod is located between the flexible airbag and the equipment in the cabinet.

[0020] By adopting the above technical solution, during the expansion of the flexible airbag, the blocking rod can prevent the flexible airbag from expanding in the direction close to the device, reducing the collision between the flexible airbag and the device, thereby helping to reduce the impact on the device. In addition, the blocking rod occupies a small space, which helps to reduce the impact on the flow of hot air.

[0021] In a specific feasible implementation scheme, the dust box includes a pull-out box body and a guide card plate, the guide card plate is fixedly connected to the pull-out box body, the upper surface of the pull-out box body is provided with an opening, the cabinet body is provided with a pull-out groove, the groove wall of the pull-out groove is provided with a guide groove, the pull-out box body is inserted in the pull-out groove, the guide card plate is inserted in the guide groove, and the pull-out box body is located below the dustproof net.

[0022] By adopting the above technical solution, the drawer box body can be pulled out from the drawer slot, which makes it easy to pour out the dust in the drawer box body, and the guide card plate helps to reduce the shaking of the drawer box body.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] This application can reduce the dust on the dustproof net from falling on the equipment in the cabinet, thereby helping to reduce the impact of dust on the equipment in the cabinet, and at the same time, can reduce the impact on the heat dissipation of the cabinet, so that the cabinet can dissipate heat normally;

[0025] The present application can reduce the damage of the flexible expansion bag due to excessive pressure by providing an air jet pipe, an elastic plug, an exhaust pipe and an exhaust control valve, and can also blow off the dust on the dustproof net, which is helpful for cleaning the dust;

[0026] The present application provides a flexible airbag and a rolling strip so that the flexible expansion bag remains relatively flat after expansion, which helps dust fall into the dust collection box, and the flexible expansion bag can automatically shrink after exhausting.
