working principle:

First, the device is transported to the work site, and the device is dismounted, because a rotating block 32 is provided in the limiting block 31 , so that the threaded sleeve 33 is rotatably connected with the limiting block 31 . First, rotate the threaded sleeve 33, so that the threaded rod 30 slowly rotates into the threaded sleeve 33, so that the two connecting plates 29 slide in the two sliding grooves 28, so that the mounting plate 27 moves together, and then the drum 36 leaks out of the concave Slot 24.

When all the threaded rods 30 enter the threaded sleeve 33, the bottom end of the drum 36 is in contact with the ground, and the support block 34 is separated from the ground. At this time, the shock-absorbing spring 26 on the connecting rod 25 recovers due to the elastic force, which helps The operator reduces the resistance when rotating the threaded sleeve 33, so that the operator can push the device to move, which solves the problem that the traditional power distribution cabinet needs to rely on auxiliary equipment for transportation, and the operation is simple, convenient and labor-saving.

When the device is moved to the base 1 on the work site, align the device, and then rotate the threaded sleeve 33 again, so that the drum 36 is slowly retracted into the groove 24. After rotating several times, the support block The bottom end of 34 is in contact with the top end of the base 1 to provide support for the housing 2 and continue to rotate the threaded sleeve 33 .

When the drum 36 is completely retracted into the groove 24 and stops rotating, the handling process is completed. At this time, the bottom end of the damping pad 37 is fitted with the top end of the base 1, and the bolts on the two limit blocks 31 are rotated to pass the limit The block 31 fixes the base 1 and the housing 2, so that the installation of the device is completed.

In this way, when the device vibrates, both the shock-absorbing pad 37 and the shock-absorbing spring 26 can provide shock-absorbing and buffering for the device, so that the device can operate better. This device is officially put into use.

Turn on the power of the fan 4, the wind generated in this way is blown into the casing 2 through the blowing hole 5 for heat dissipation, and the cooling hole 6 is installed with a screen to prevent dust from entering the interior, so that a part of the hot air will blow along the through hole 20. into the groove 24, which can prevent moisture from entering the casing 2 to a certain extent.

And two filter screens 22 are arranged in the through hole 20 , and activated carbon particles 23 are filled between the two filter screens 22 . In this way, the activated carbon particles 23 can absorb the moisture in the groove 24, and the third one-way valve 21 can prevent moisture from entering the casing 2 along the through hole 20, which can prevent the accumulation of more and more moisture.

In addition, a small part of the hot air is blown into the groove 24 at all times to reduce the generation of moisture, thereby avoiding potential safety hazards and indirectly increasing the service life of the internal components.

When the internal heat is too much and the fan 4 is exhausting, the power supply of the two vibrators 39 is activated at this time, so that the two reinforcing plates 9 vibrate back and forth, so that the piston cylinder 13 will continuously move left and right, and the piston 14 passes through the fixed rod. 18 is fixed, so that when the piston cylinder 13 moves, the hot air is sucked into the piston cylinder 13 along the first L-shaped cannula 11, and then discharged to the outside through the second L-shaped cannula 16.

The first one-way valve 12 and the second one-way valve 17 ensure the normal operation of the device, which can help the device to dissipate heat, thereby increasing the heat dissipation rate of the device and preventing the device from causing safety hazards due to overheating.

In addition, the device is provided with two reinforcing plates 9, the thickness of the reinforcing plate 9 is one-third of the traditional wall thickness, and the wall thicknesses on both sides of the housing 2 are also equivalent to one-third of the original, and the two are fixed by fixing The compression spring 19 on the rod 18 is used for buffering, so that the protective effect of the original wall thickness can be achieved, and the material and the production cost can be saved.
