Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, for the utility model discloses a stable in structure's insulating switch board, including inside cavity and be used for depositing the cabinet body 1 of electrical component. Two opposite side walls of the cabinet body 1 are symmetrically provided with two ventilation holes 11, and the ventilation holes 11 penetrate through the side walls of the cabinet body 1 along the length direction of the cabinet body 1. An exhaust fan 111 is fixedly arranged at one end of the ventilation hole 11 close to the cabinet body 1, and the air inlet directions of the two rows of fans 111 are opposite. The non-woven fabric 2 covering the end part of the vent hole 11 is fixedly arranged on the outer side wall of the cabinet body 1, the temperature sensor 12 is fixedly arranged in the cabinet body 1, and the temperature sensor 12 is electrically connected with the controller of the exhaust fan 111.
When the temperature sensor 12 detects that the temperature inside the cabinet 1 is too high, the temperature sensor 12 sends a signal to the controller of the exhaust fan 111, and the two rows of fans 111 start to operate. One of the exhaust fans 111 drives the air outside the cabinet body 1 to enter the cabinet body 1, the other exhaust fan 111 drives the air inside the cabinet body 1 to leave the cabinet body 1, and the two rows of the fans 111 effectively increase the flow speed and the flow of air convection at the air vent 11, so that the internal temperature of the cabinet body 1 can be effectively reduced, and the overheating load of the electric elements inside the cabinet body 1 can be avoided. The non-woven fabrics 2 effectively intercept dust outside the cabinet body 1, dust is not easy to adhere to the electric elements in the cabinet body 1, and the heat dissipation effect of the cabinet body 1 is good. When the temperature sensor 12 detects that the temperature in the cabinet 1 is reduced to a normal value, the exhaust fan 111 stops working due to the signal of the temperature sensor 12, so that the heat dissipation energy consumption is low, and the environmental protection performance is good.
Referring to fig. 1, a fixing frame 3 surrounding a ventilation hole 11 is provided on an outer side wall of a cabinet body 1, and the fixing frame 3 is slidably connected to the cabinet body 1 along a depth direction of the ventilation hole 11. The upper and lower parts of the fixed frame 3 are respectively provided with a releasing shaft 51 and a winding shaft 52, and the axes of the releasing shaft 51 and the winding shaft 52 are parallel to the width direction of the cabinet 1. The releasing shaft 51 and the winding shaft 52 are both rotationally connected with the cabinet body 1, and two ends of the non-woven fabric 2 are respectively connected with the releasing shaft 51 and the winding shaft 52. The cabinet body 1 is fixedly provided with a dustproof box 55 corresponding to the release shaft 51, and the release shaft 51 and the non-woven fabric 2 on the release shaft 51 are both covered by the dustproof box 55. The displacement of the non-woven fabrics 2 is realized in the rotation of user's accessible release axle 51 and rolling axle 52, compresses tightly non-woven fabrics 2 on the cabinet body 1 lateral wall through the slip of fixed frame 3 to can be when adhering to too much dust on non-woven fabrics 2, can conveniently change non-woven fabrics 2.
Referring to fig. 2 and 3, the cabinet 1 is provided with a fixing mechanism 4 for a user to fix a sliding position of the fixing frame 3, and the fixing mechanism 4 includes a locking spring 41, an electromagnet 42, and a metal sheet 43. Both ends of the locking spring 41 are respectively connected with the fixed frame 3 and the cabinet body 1, and the elastic force of the locking spring 41 drives the fixed frame 3 to slide towards the non-woven fabric 2. The electromagnet 42 and the metal sheet 43 are oppositely arranged, and the electromagnet 42 and the metal sheet 43 are respectively fixed on the cabinet body 1 and the fixed frame 3. The elastic force of the locking spring 41 normally keeps the fixing frame 3 pressed against and fixed to the nonwoven fabric 2. When the non-woven fabric 2 needs to be replaced, the power-on state of the electromagnet 42 is changed, the fixed frame 3 is driven to slide away from the cabinet body 1 through the magnetic repulsion force between the electromagnet 42 and the metal sheet 43, so that a gap for the non-woven fabric 2 to move exists between the fixed frame 3 and the outer side wall of the cabinet body 1.
Referring to fig. 4, the winding shaft 52 is connected with a micro motor 54 in a transmission manner, and a tension torsion spring 53 is fixedly arranged on the cabinet 1 corresponding to the releasing shaft 51. Both ends of the tension torsion spring 53 are respectively connected with the release shaft 51 and the cabinet 1, and the elasticity of the tension torsion spring 53 prevents the release shaft 51 from rotating to release the non-woven fabric 2. The user accessible micro motor 54 drives the rolling axle 52 rotatory, and the non-woven fabrics 2 that the dust is attached to in the winding of rolling axle 52 winding rolling, and the elasticity of tensioning torsional spring 53 makes the tensioning of non-woven fabrics 2 to realize the displacement under the non-woven fabrics 2 tensioning state.
Referring to fig. 1, an air speed sensor 112 is fixedly disposed in the ventilation hole 11, the air speed sensor 112 is electrically connected to both the exhaust fan 111 and the controller of the micro-motor 54, and the controller of the micro-motor 54 is electrically connected to the controller of the electromagnet 42. The user accessible air velocity transducer 112 detects the wind speed in the ventilation hole 11, works when exhaust fan 111 and the wind speed is less than specified numerical value, explains that too much dust has been attached to on the non-woven fabrics 2 and has influenced exhaust fan 111 and accelerate the effect of air convection, and the on state of electro-magnet 42 changes and micro motor 54 begins to work, and fixed frame 3 slides and non-woven fabrics 2 displacement to realize the automatic change of non-woven fabrics 2, it is more convenient to use.
The implementation principle of the embodiment is as follows: prevent through non-woven fabrics 2 that the outer dust of the cabinet body 1 gets into the cabinet body 1 in, effectively reduce the cabinet body 1 in because of the low possibility of dust heat dissipation efficiency that gathers, exhaust fan 111's heat dissipation burden is little, simultaneously through the rotation of release axle 51 and rolling axle 52 to and the automatic change of non-woven fabrics 2 is realized in sliding of fixed frame 3, the non-woven fabrics 2 is changed untimely not influence the possibility of this cabinet body 1 radiating effect low.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
