Detailed Description
Referring to fig. 1, the tremble dust-removing type power transformation cabinet provided by the invention comprises: an air inlet pipe 1, an air outlet pipe 2, a first hose 3, a second hose 4, a fan 5 and a cabinet 6.
The first hose 3 is arranged on the cabinet 6 and communicated with the air inlet, and the air inlet pipe 1 is arranged on the cabinet 6 through a spring 7. The air inlet pipe 1 has a first end connected to and communicating with the first hose 3 and a second end disposed lower than the first end. A dust adsorption mechanism 8 is arranged in the air inlet pipe 1. In this way, the air inlet pipe 1 is elastically installed through the spring 7 and is in soft connection with the air inlet. When the spring 7 stretches out and draws back, the air inlet pipe 1 can be driven to vibrate, and therefore dust adsorbed by the dust adsorption mechanism 8 is desorbed.
The air outlet pipe 2 is arranged on the cabinet body 6 and communicated with the air outlet, and the second end of the air inlet pipe 1 is positioned in the air outlet direction of the air outlet pipe 2. The second hose 4 is connected between the air inlet pipe 1 and the air outlet pipe 2, and one end of the second hose 4 connected with the air inlet pipe 1 is sealed. The spring 7 and the second hose 4 are positioned at two opposite sides of the air inlet pipe 1, and the second hose 4 is bent in an original length state of the spring 7. I.e. the second hose 4 compresses the spring 7 in a straightened state.
The fan 5 is installed at the air inlet or the air outlet. The electromagnetic valve 9 is arranged in the air outlet pipe 2, and the electromagnetic valve 9 is positioned at one side of the second hose 4 away from the air outlet along the air flow direction in the air outlet pipe 2. Under the closed state of the electromagnetic valve 9, the air outlet pipe 2 is blocked, so that the air pressure in the air outlet pipe 2 and the second hose 4 is increased along with the continuous operation of the fan 5, and when the air pressure in the second hose 4 reaches a preset value, the second hose 4 is straightened.
The cabinet 6 is also provided with a delay switch 10, the fan 5 and the electromagnetic valve 9 are connected with a power supply through the delay switch 10, and in the closed state of the delay switch 10, the fan 5 is opened and the electromagnetic valve 9 is closed, so that the air inlet pipe 1 is used for air inlet and exhaust to the air outlet pipe 2, and the air pressure in the air outlet pipe 2 and the second hose 4 is increased. In the off state of the delay switch 10, the fan 5 is stopped and the electromagnetic valve 9 is opened, so that the air flow in the air outlet pipe 2 and the second hose 4 is discharged, the pressure is reduced, and the second hose 4 returns to the soft state.
In this embodiment, the delay switch 10 is a normally closed switch, which is installed on the swing track of the air inlet pipe 1, when the second hose 4 is straightened, the touch delay switch 10 of the air inlet pipe 1 is opened, and the delay switch 10 is automatically closed after being opened. Specifically, in the present embodiment, the selection of the delay switch 10 is based on the prior art.
In the embodiment, when the delay switch 10 is closed, the cabinet body is subjected to air inlet through the air inlet pipe 1 under the action of the fan 5, and the dust adsorption mechanism 8 performs dust removal and purification on the air flow entering the cabinet body through the air inlet pipe 1, so that dust pollution in the cabinet body is avoided; meanwhile, the air flow exhausted by the cabinet body stays in the air outlet pipe 2; when the second hose 4 is straightened, the spring 7 is extruded, the delay switch 10 is turned off within a certain time, and when the delay switch 10 is turned off, the fan 5 is turned off, so that the air inlet pipe 1 stops air inlet, and meanwhile, the air inlet pipe 1 starts to tremble under the rebound effect of the spring 7 to carry out dust removal of the dust adsorption mechanism 8; and the electromagnetic valve 9 is opened, the air outlet pipe 2 starts to exhaust air and blows dust discharged from the inlet section of the air inlet pipe 1, so that dust is prevented from accumulating at the inlet end of the air inlet pipe 1 and being secondarily adsorbed after the fan 5 is started.
Specifically, in this embodiment, the fan 5 is installed at the air outlet, so that the equipment inside the cabinet body can be prevented from operating under high air pressure.
In a further embodiment of the invention, the air inlet pipe 1 is arranged on the cabinet 6 through at least two springs 7, and the springs 7 are distributed along the axial direction of the air inlet pipe 1. Thus, the stable installation of the air inlet pipe 1 can be further improved, and the air inlet pipe 1 is prevented from falling off. Specifically, in this embodiment, in order to facilitate dust discharge of the air inlet pipe 1, the air inlet pipe 1 is a linear pipe.
In a further embodiment of the invention, the time delay switch 10, the fan 5 and the solenoid valve 9 are connected in series to ensure the synchronous action of the fan 5 and the solenoid valve 9.
In this embodiment, the air outlet sets up at cabinet body 6 top, and the air intake is close to cabinet body 6 bottom setting to guarantee that the inside air current of cabinet body 6 flows comprehensively, improve ventilation effect. Further, the air outlet is far away from the side wall of the cabinet body 6 where the air inlet is.
In this embodiment, the second end of the air inlet pipe 1 faces the ground, and the air inlet pipe 1 is vertically installed to facilitate dust removal. In the present embodiment, the dust adsorbing mechanism 8 is composed of a plurality of layers of filter screens.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to apply equivalents and modifications to the technical solution and the inventive concept thereof within the scope of the present invention.
