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 impurities and the like can be covered in the heat dissipation holes in the box body, generally in order to prevent external rainwater from entering the box body, the heat dissipation holes in the box body are usually made into a rectangular D shape with downward openings, the heat dissipation holes in the box body and the box body are integrally designed, and for the power distribution cabinet operating for a long time, the heat dissipation holes are covered with a large amount of dust impurities and the like, so that the cleaning from the box body is very troublesome;
in order to overcome the defects, the invention designs a detachable power distribution cabinet for power equipment.
The power distribution cabinet main body 1 and the heat dissipation part 2 adopt a detachable design (the existing design as a whole):
the installation and the dismantlement of radiating part 2 at first will prevent seepage case 3 inside interval groove block on the through-hole 12 inner wall, then manual holding down the depression bar 146 on the switch board main part 1 and push down, drive square bar 142 and slide down along outer tube 141 inner wall, reset spring 144 receives the elastic deformation, drive interior slide bar 143 and combined rod 145 synchronous downstream (interior slide bar 143 adopts thick and thin pole to constitute, thin pole is located outer tube 141, thick pole carries out the spacing), until limiting plate contact outer tube 141 on square bar 142, the depression bar 146 stop motion down, this moment aligns the frame 22 on the radiating part 2 and inwards bulldozes in installing frame 13, the inside sealing strip of installing frame 13 takes place elastic deformation, then loose down depression bar 146, interior slide bar 143, combined rod 145 and down depression bar 146 all receive reset spring 144's elastic action, square bar 142 slides along outer tube 141 inner wall, until combined rod 145 is complete slide into the sleeve pipe (reset spring 144 still is in the compressed state this moment, the sleeve pipe lower port adopts horn mouth design sleeve pipe, the combined rod is located in the sleeve pipe, this moment, the frame is held down by force down) and the frame 22 is in line with the time with the installation frame 211 is in the place with the help of the frame 211, can be combined into the whole with the following the easy operation of the inside operation of the installation frame 13 and then can be combined into the whole with the sealing strip 211 simply when the radiating part is combined with the inside the 2 (the inside part is easy to be combined with the frame 145) and easy to have been combined with the fact 1 and easy piece's 211 has been just to follow's time's easy's operation.
Detachable design advantage: firstly, the design of the radiating plate 23 on the radiating part 2 is consistent with that of the radiating hole on the traditional box body, which is made into a prolate D shape with a downward opening, the cleaning is carried out from the inside of the box body, which is very troublesome, and the box body 11 and the radiating part 2 are made to be detachable by means of the mounting frame 13, the combining piece 14 and the sleeve 211, and the radiating part 2 is directly taken down (preferably water washing) during cleaning; secondly, the clamping holes of the mounting frame 13 face outwards, and when the frame 22 on the panel 21 is clamped into the mounting frame 13, the sealing strips are matched, so that external rainwater can be effectively prevented from penetrating into the box 11; thirdly, when outside rainfall and amount of wind are great, rain fog drops into box 11 on heating panel 23 easily, and prevention of seepage case 3 plays fine collecting action this moment, and the accumulated rainwater in prevention of seepage case 3 can also collect the dust that drops on heating panel 23, makes box 11 and radiating part 2 detachable, makes things convenient for prevention of seepage case 3 to take out the clearance fast to after the installation, panel 21 plays fixed limiting action to prevention of seepage case 3, avoids the inside rainwater of prevention of seepage case 3 too much to take place to turn on one's side.
Meanwhile, in some remote areas, the disassembled heat dissipation part 2 is inconvenient to clean quickly, and the invention is also designed with a dust removal part 25:
the dust removing piece 25 and the fixing seat 24 on the outer surface of the panel 21 are detachably mounted through the thread group (the condition allows the panel 21 and the heat dissipation plate 23 to be separated from the dust removing piece 25 and washed independently), when the dust removing piece is integrally held by a pull rod 258 on the dust removing piece 25, the reciprocating block 252 is driven to slide back along the inner part of the sliding rail 251 (initially, the magnetic design of the reciprocating block 252 adsorbs the top of the inner wall of the sliding rail 251), the friction wheel 254 is driven to roll along the outer surface of the panel 21 (the two are tightly attached), the shaft 253 is driven to rotate around the inner part of the reciprocating block 252, the hard rod 255 and the brush 256 are driven to synchronously rotate (the length of the brush 256 can be extended to the inner wall of the heat dissipation plate 23), and then the brush 256 can continuously clean dust impurities and the like on the inner wall of the heat dissipation plate 23 quickly.
First, the tip of hard pole 255 and the non-center department installation of friction pulley 254 tip, when the brush 256 is rotatory to clear up fast of heating panel 23 inner wall dust impurity etc. and the brush 256 receives the extrusion degree of heating panel 23 and changes constantly, cooperates the vibration of hard pole 255, is favorable to the inside absorption dust impurity of brush 256 to break away from fast, and the irregular contact heating panel 23 inner wall of brush 256 makes can fully contact between heating panel 23 inner wall and the brush 256 simultaneously, is favorable to improving the cleaning performance.
The second advantage is that the friction wheel 254 and the panel 21 rely on friction force to drive the hard rod 255 and the brush 256 to rotate synchronously, and because the sliding speed of the pull rod 258 is changed (manual operation), when the pull rod 258 slides fast, the friction wheel 254 and the panel 21 have a relatively short-distance rolling condition (sliding), and then the brush 256 passing through the same position on the heat dissipation plate 23 is different (the deformation amount and the bending angle of the brush 256 are different), so that the dead angle of the heat dissipation plate 23 can not be cleaned. Meanwhile, the screw thread group in the sliding rail 251 is rotated by the screw driver, the interval between the sliding rail 251 and the panel 21 is adjusted, and the friction force between the friction wheel 254 and the panel 21 is changed (the interval is small, the resistance is large, the quick pulling can be realized, the interval is large, the resistance is small, the quick pulling is required, and the continuous sliding is avoided).
The advantage three, hard pole 255 circumference surface fixedly connected with and brush 256 crisscross elastic plate 259 that distributes, elastic plate 259 and panel 21 contactless, when hard pole 255 and brush 256 synchronous revolution, drive the synchronous revolution of a plurality of groups of elastic plates 259, the blowing that elastic plate 259 produced accelerates heating panel 23 inner wall clearance, improves the cleaning performance, and elastic plate 259 can take place slight elastic deformation simultaneously, accelerates the vibration of hard pole 255, the cooperation is bloied, accelerates the inside absorptive dust impurity of brush 256 and breaks away from, elastic plate 259 and separates the brush 256, avoids the brush 256 winding together side by side.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; these modifications or substitutions do not depart from the essence of the corresponding technical solutions from the protection scope of the technical solutions of the embodiments of the present invention.
