The first embodiment is as follows:
referring to fig. 1-3, a self-drying outdoor power distribution cabinet comprises a cabinet body 1, wherein a plurality of electric elements 2 are installed in the cabinet body 1, a plurality of through holes 3 are formed in the side wall of the cabinet body 1, a circular groove 4 communicated with the through holes 3 is formed in the side wall of the cabinet body 1, and a rotating disc 5 is connected in the circular groove 4 in a sealing and rotating mode.
It should be noted that the rotating disc 5 is made of two materials, namely, heat conducting material and heat insulating material, and the distribution of the heat insulating material portion 52 can refer to fig. 2 and 3 in the actual manufacturing process, that is, the heat insulating material portion 52 blocks the heat transfer between the plurality of material storage tanks 51.
A plurality of stock chutes 51 have been seted up along its circumference equidistant to the lateral wall of rolling disc 5, and the intussuseption 51 is filled with the silica gel granule, and a plurality of gas holes 511 have all been seted up to two relative lateral walls on the horizontal direction of stock chute 51.
It should be noted that, the number of the air holes 511 is large, and the aperture of the air holes 511 is smaller than the diameter of the silica gel particles, so that the air can be ensured to smoothly pass through the material storage tank 51, and the silica gel particles can be prevented from falling off from the air holes 511, and although the aperture of the air holes 511 is small, the number of the air holes 511 is large, the total ventilation area is considerable, and the original ventilation effect of the power distribution cabinet is not affected.
Fixedly connected with heat conduction rubber strip 21 on the inner wall of circular slot 4, and the one end and the electric elements 2 fixed connection of circular slot 4 are kept away from to heat conduction rubber strip 21, and exhaust hole 6 has been seted up to the interior bottom of circular slot 4, seted up the venthole 512 with the feed bin 51 intercommunication on the circumference lateral wall of rolling disc 5.
In this embodiment, the air outside the cabinet 1 can only flow along the through holes 3 when entering the cabinet 1. In this process, moist air will be at first got into the stock chest 51 that is arranged in through-hole 3, and moist air will be by the silica gel granule in the stock chest 51 after absorbing moisture, reentrant cabinet body 1 to guarantee to get into the air drying of cabinet body 1, in order to prevent to take place the condensation phenomenon in cabinet body 1.
When the silica gel particles in the storage tank 51 in the through hole 3 absorb a certain amount of moisture and the water absorption rate thereof begins to decrease, the mass in the storage tank 51 increases, as shown in fig. 3, the rotating disc 5 is forced to rotate clockwise until the storage tank 51 absorbing a large amount of moisture is vertically downward, and the air outlet 512 of the storage tank 51 is communicated with the air outlet 6. Meanwhile, the heat conducting rubber strip 21 continuously guides the heat generated by the electric element 2 into the inner bottom of the circular groove 4, so that the silica gel particles absorbing a large amount of moisture can be rapidly heated, the absorbed moisture can be rapidly evaporated, the silica gel particles are discharged out of the cabinet body 1 along the exhaust hole 6, and meanwhile, the quality of the silica gel particles in the storage tank 51 is recovered as before.
When the rotating disc 5 rotates, the other material storage tank 51 is conveyed into the through hole 3, the air passing through the through hole 3 is dried, and after sufficient moisture is adsorbed in the material storage tank 51, the rotating disc 5 is pushed to rotate clockwise under the action of gravity. So recycling, on the one hand, can guarantee that the air through-hole 3 all is carried out the drying by the silica gel granule adsorbed moisture in each stock chest 51, and on the other hand can guarantee all the time that the silica gel granule in individual stock chest 51 has good water absorption rate, makes this device can long-term recycle, and need not the manual maintenance.
In addition, it is worth mentioning that the energy for absorbing the water and evaporating in the silica gel particles is forced to be provided by the heat generated by each electrical element 2, so that the device can continuously consume the heat generated by each electrical element 2 when in use, and can accelerate the heat dissipation efficiency of the electrical elements 2, thereby ensuring that the device also has good heat dissipation performance.
Example two:
referring to fig. 4-5, the difference from the first embodiment is that a plurality of electromagnets 7 are embedded on the circumferential side wall of the rotating disc 5, and two wiring terminals of each electromagnet 7 are respectively and fixedly connected to two opposite inner walls of the adjacent material storage tanks 51, a strip-shaped groove 8 is formed in the side wall of the cabinet body 1, and an iron sliding plug 9 is slidably connected in the strip-shaped groove 8.
It should be noted that, the cabinet body 1 in this embodiment is made of engineering plastics, and compared with the conventional iron power distribution cabinet, the power distribution cabinet has the advantages of low density, light weight, impact resistance and good insulating property, and more importantly, the movement of the electromagnet 7 is not affected.
The side wall of the sliding plug 9 is in close contact with the inner wall of the strip-shaped groove 8, the sliding plug 9 is provided with a one-way air hole 91, the inner wall of the cabinet body 1 is provided with a one-way air groove 82 communicated with the strip-shaped groove 8, and the outer wall of the cabinet body 1 is provided with an air outlet groove 81 communicated with the strip-shaped groove 8.
In this embodiment, after the silica gel particles in the storage tank 51 in the through hole 3 absorb a certain amount of moisture, the terminals disposed on two opposite inner walls of the storage tank 51 and the water in the storage tank 51 form a closed loop, so that the power supply circuit of the electromagnet 7 is turned on.
Then, the electromagnet 7 will generate magnetic force after being energized, and will be attracted by the iron sliding plug 9 in the strip-shaped groove 8, and will push the rotating disc 5 to rotate, so that the material storage tank 51 absorbing moisture is vertically downward, and at the same time, the electromagnet 7 will also attract the sliding plug 9 to move upward. After the storage tank 51 is dried, the power supply circuit of the electromagnet 7 is disconnected, and the sliding plug 9 loses the attraction of the magnetic force and naturally falls under the action of gravity.
As in the first embodiment, after the rotating disc 5 rotates, another material storage tank 51 is also arranged in the through hole 3, so that the continuous recycling of the device is ensured.
Through the magnetic force with electro-magnet 7 drive rolling disc 5 and rotate, the silica gel granule in the stock chest 51 only needs to absorb a small amount of moisture just can make electro-magnet 7 circular telegram and promote rolling disc 5 and rotate, compares the drive mode of gravity in the embodiment one, and the required absorbent moisture content greatly reduced of silica gel granule can make rolling disc 5's rotation cycle shorten greatly. On the one hand, can keep the lower moisture content of each stock chest 51 silica gel granule, improve silica gel granule's water absorption rate greatly to further promote the degree of dryness that gets into the internal air of cabinet 1, on the other hand, the silica gel granule that the moisture content is lower is when the heat absorption, and the moisture evaporation time is short, fast, thereby improves the work efficiency of whole device.
And when the rolling disc 5 rotates, the process that each electromagnet 7 is switched on and off, the sliding plug 9 also moves up and down in the strip-shaped groove 8 in a reciprocating manner, and the air inside the cabinet body 1 can be continuously pumped out under the current limiting effect of the one-way air hole 91 and the one-way air groove 82, so that the interaction of the air inside and outside the cabinet body 1 is greatly promoted, and the heat dissipation efficiency of the device is further improved.
The above description is only for the 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 considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
