Referring to fig. 1 to 7, the power distribution cabinet is widely used, and is usually installed outdoors, after the power distribution cabinet operates for a long time, a large amount of dust and impurities can be covered in the heat dissipation holes in the box body, generally, in order to prevent external rainwater from entering the inside of the box body, the heat dissipation holes in the box body are generally made into a flat and long D shape with a downward opening, and the heat dissipation holes in the box body and the box body are designed in an integrated manner, for the power distribution cabinet operating for a long time, a large amount of dust and impurities are covered in the heat dissipation holes, and therefore, the cleaning from the inside of the box body is very troublesome;
in order to overcome the defects, the invention provides a detachable power distribution cabinet for power equipment.
The detachable design (the existing integrated design) is adopted between the power distribution cabinet main body 1 and the heat dissipation part 2:
the installation and the disassembly of the heat dissipation part 2 are realized by clamping a middle groove inside the anti-seepage box 3 on the inner wall of the through hole 12, then manually holding the lower pressure rod 146 on the power distribution cabinet main body 1 and pressing downwards to drive the square rod 142 to slide downwards along the inner wall of the outer connecting tube 141, the reset spring 144 is pressed to generate elastic deformation to drive the inner sliding rod 143 and the connecting rod 145 to synchronously move downwards (the inner sliding rod 143 is composed of thick and thin rods, the thin rods are positioned in the outer connecting tube 141 and are limited by the thick rods), until the limiting plate on the square rod 142 contacts the outer connecting tube 141, the lower pressure rod 146 stops moving, at the moment, the frame 22 on the heat dissipation part 2 is aligned with the installation frame 13 and pushed inwards, the sealing strip inside the installation frame 13 generates elastic deformation, then the lower pressure rod 146 is loosened, the inner sliding rod 143, the connecting rod 145 and the lower pressure rod 146 are reset under the elastic action of the reset spring 144, the square rod 142 slides along the inner wall of the outer connecting tube 141 until the connecting rod 145 completely slides into the connecting rod 145, until the connecting rod 145 completely slides into the sleeve 211 (at the connecting rod 211 is still in a compressed state, the horn-shaped opening is designed, and the connecting rod 145 is embedded with the sleeve 145, and the heat dissipation part 2, and the heat distribution cabinet main body can be simply disassembled by the simple operation (the simple and the simple operation of the heat dissipation part 211).
The detachable design has the advantages that: firstly, the heat dissipation plate 23 on the heat dissipation part 2 is designed to be consistent with the shape of a flat and long part D with a downward opening made of heat dissipation holes on a traditional box body, and the box body and the heat dissipation part 2 are made into a detachable type by virtue of the mounting frame 13, the combining piece 14 and the sleeve 211 during cleaning, so that the heat dissipation part 2 can be directly taken down (preferably washed) during cleaning; secondly, the clamping hole of the mounting frame 13 faces outwards, and when the frame 22 on the panel 21 is clamped into the mounting frame 13, external rainwater can be effectively prevented from permeating into the box body 11 by matching with the sealing strip; thirdly, when external rainfall and the amount of wind are great, rain and fog easily drop into the box body 11 on the heat dissipation plate 23, at the moment, the anti-seepage box 3 plays a good collecting role, the accumulated rainwater in the anti-seepage box 3 can also collect dust falling off from the heat dissipation plate 23, the box body 11 and the heat dissipation part 2 are made into a detachable type, the anti-seepage box 3 can be conveniently taken out and cleaned quickly, in addition, after the anti-seepage box is installed, the panel 21 plays a fixing and limiting role for the anti-seepage box 3, and the phenomenon that the rainwater in the anti-seepage box 3 is too much turned on the side is avoided.
Meanwhile, in some remote areas, the heat dissipation part 2 after being disassembled is inconvenient to clean quickly, and the invention is also provided with a dust removal part 25:
the fixing base 24 of dust removal piece 25 and panel 21 surface passes through thread group demountable installation (the condition allows, panel 21, heating panel 23 also can separately independent washing with dust removal piece 25), when whole, pull rod 258 on the dust removal piece 25 is held to the manual, drive reciprocating block 252 along the inside pull-back slip of slide rail 251 (during the beginning, the magnetic design of reciprocating block 252 adsorbs slide rail 251 inner wall top), it rolls (the two closely laminates) along panel 21 surface to drive friction pulley 254, drive axostylus axostyle 253 around reciprocating block 252 inside rotation, drive hard pole 255 and brush 256 synchronous revolution (the length of brush 256 can extend to heating panel 23 inner wall), and then brush 256 can incessantly carry out quick clearance to heating panel 23 inner wall dust impurity etc..
Advantage one, the tip of bull stick 255 and the installation of friction pulley 254 tip off-center department, when brush 256 is rotatory to clearing up fast heating panel 23 inner wall dust impurity etc. brush 256 changes constantly, the extrusion degree that brush 256 received heating panel 23 changes, the vibration of cooperation bull stick 255 is favorable to the inside dust impurity that adsorbs of brush 256 to break away from fast, brush 256's irregular contact heating panel 23 inner wall simultaneously, make and to fully contact between heating panel 23 inner wall and the brush 256, be favorable to improving the cleaning effect.
The second advantage, friction wheel 254 and panel 21 rely on frictional force, drive the synchronous revolution of stiff pole 255 and brush 256, because pull 258 slides the rate and changes constantly (manual operation), so when pull 258 slides very fast, there is the rolling condition of relative short distance (skidding) between friction wheel 254 and the panel 21, and then the brush 256 that passes through same position on the heating panel 23 is different (brush 256 deformation volume and bending angle are different), avoids the unable circumstances of clearing up of heating panel 23 dead angle. Meanwhile, the screw thread group in the slide rail 251 is rotated by the screwdriver, the distance between the slide rail 251 and the panel 21 is adjusted, and the friction force between the friction wheel 254 and the panel 21 is changed (the distance is small, the resistance is large, the fast pulling is realized, the distance is large, the resistance is small, the slow pulling is needed, and the continuous slipping is avoided).
Three of the advantage, surface fixedly connected with and the crisscross bullet board 259 that distributes of brush 256 outside the circumference of wand 255, bullet board 259 and panel 21 contactless, when wand 255 and brush 256 synchronous revolution, drive a plurality of groups bullet board 259 synchronous revolution, blow that bullet board 259 produced, the clearance of heating panel 23 inner wall accelerates, improve the cleaning effect, bullet board 259 can take place light and little elastic deformation simultaneously, the vibration of wand 255 accelerates, the cooperation is bloied, the inside adsorbed dust impurity of brush 256 breaks away from with higher speed, bullet board 259 separates brush 256, avoid the winding of brush 256 side by side together.
The above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present invention.
