Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, it being understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
Referring to fig. 1-2, the present invention provides a novel drawer type switch cabinet, including a cabinet body 1 and a drawer cabinet 11 located inside the cabinet body, wherein the drawer cabinet 11 is slidably connected to the cabinet body 1, and each drawer cabinet 11 is provided with a handle switch 12; the cabinet body 1 is connected with a plurality of drawer cabinets 11 in a sliding mode, an independent control unit is arranged in each drawer cabinet 11, and each control unit can realize independent control over the drawer cabinets 11 through handle switches 12 on the drawer cabinets 11. The air duct comprises an air inlet duct 13 and an air outlet duct 17, the air outlet duct 17 is respectively positioned at the left side and the right side of the cabinet body 1, and the air inlet duct 13 is positioned in the middle of the cabinet body 1; the drawer cabinet 11 is hollow and is provided with an exhaust fan and a temperature control assembly, the temperature control assembly is electrically connected with the exhaust fan, the exhaust fan is positioned on one side of the air outlet channel, the front end of the exhaust fan is provided with a check valve, and a wind shield 14 at the upper end of the check valve is hinged with the inner wall of the air outlet channel 17. The operating principle of check valve is fairly simple, and the quality of deep bead 14 is lighter, can upwards lift when being blown by wind, and after airing exhaust, deep bead 14 can automatic the drooping to realize one-way ventilation's effect, dust particle can not the reverse entering drawer cabinet 11 like this. The two sides of the cabinet body 1 are provided with air outlet channels 17, the middle part of the cabinet body 1 is provided with an air inlet channel 13, the air inlet channel 13 introduces external natural air, and the external air passes through the check valve of the drawer cabinet 11 and then is discharged from the air outlet channels 17 under the action of the exhaust fan, so that the purpose of heat dissipation is realized.
Preferably, the cabinet 1 of the present invention is provided with a waterproof board 18 at the upper end thereof, and the waterproof board 18 is triangular. The use place of part cabinet body 1 is comparatively harsh, utilizes waterproof board 18 can reduce the entering of moisture, and the apex angle of waterproof board 18 needs to set up lewis hole 15, and lewis hole 15 except can being used for hoist and mount cabinet body 1, can also be used for fixing. When a plurality of cabinets body 1 placed side by side, can utilize nut component to connect fixedly with lifting eye 15 on the adjacent cabinet body 1, can reduce and rock to increase overall equipment stability.
In addition, the middle part of the waterproof board 18 of the utility model is provided with a blower which is respectively connected with an air outlet channel. When a plurality of air discharge fans work together, the noise is great, the vibration that still can produce, when actual installation, if the integral sealing of air-out duct 17 is than higher in the cabinet body 1, can also utilize the powerful suction of air-blower, form half negative pressure state in air-out duct 17, the air can directly get into drawer cabinet 11 from air inlet duct 13 this moment, then 17 discharges in the air-out duct, forms a natural formula exhaust and radiating effect.
Further, the two side end faces of the waterproof board 18 of the present invention are covered with the dust-proof net 3. The middle of the flashing 18 should be relatively high in order to facilitate drainage, and both sides of the flashing 18 need to be covered with dust screens 3 in order to reduce the ingress of insects and dust.
Preferably, each drawer cabinet 11 of the present invention is provided with a smoke alarm device. When the electrical elements are overloaded or short-circuited for a long time, open fire is easy to appear, at the moment, the power is cut off as soon as possible and the fire is immediately saved, and the smoke alarm device can detect the fire and give an alarm in time.
