Further, the cabinet 20 further includes a door 26 disposed between the two side veneers 21, and a door frame of the door 26 is detachably connected to the adjacent side veneers 21, and the door frame is rotatably connected to the door leaf.
The principle and the beneficial effects of the invention are as follows:
according to the specification of the required power distribution cabinet, different numbers of side single plates 21 and stand columns 22 are used for being spliced to obtain power distribution cabinets with different length and width specifications, when the power distribution cabinet is assembled, a first splicing strip 212 on the side single plate 21 is spliced with a first splicing groove 211 on the other side single plate 21 in sequence to form a side plate group in the length direction or a side plate group in the width direction, a door 26 is fixedly connected on the side plate group in the length direction or the side plate group in the width direction according to requirements, each side plate group is spliced with 4 stand columns 22 in sequence to form a square cabinet 20, when the side single plates 21 and the stand columns 22 are spliced, the lower ends of a first screw 2113 and a second screw 2213 are contacted with a first clamping block 2112 or a second clamping block 2212, and as the first splicing strip 212 and the second splicing strip 222 are in clearance fit with the first splicing groove 211 and the second splicing groove 221, therefore, when the side veneers 21 and the upright posts 22 are spliced together, the friction force between the side veneers 21 and the upright posts 22 is small, the side veneers 21 and the upright posts 22 can be conveniently and quickly spliced together, after the cabinet body 20 is formed by splicing, the first screw 2113 and the second screw 2213 are enabled to move downwards by rotating the first screw 2113 and the second screw 2213 through tools, the lower ends of the first screw 2113 and the second screw 2213 squeeze the first clamping blocks 2112 and the second clamping blocks 2212, so that the first clamping blocks 2112 and the second clamping blocks 2212 are clamped into the corresponding first clamping grooves 2121 and the second clamping grooves 2221, further the adjacent side veneers 21 and the upright posts 22 are clamped together, the cabinet body 20 with a stable square frame body is prevented from being formed by moving between the adjacent side veneers 21 and the upright posts 22 in the plane direction, and the 4 upright posts 22 are fixedly connected with the bottom plate 10 through bolts, and then the upper end of the cabinet body 20 is connected with a top plate 30, and the cabinet body 20 is connected with an electric component mounting plate according to the requirement, so that the required power distribution cabinet can be obtained.
When the temperature in the cabinet 20 is at low temperature or normal temperature, the elastic air bag 242 is in a contracted state or has low expansion degree, and can not push the sliding block 241 to drive the rack 243 to move, at this time, the baffle 247 is used for sealing the air vent 232, so that the air circulation rate in the cabinet 20 is reduced, and the temperature emitted by the electric components can be increased in lower temperature environments such as winter, so that the electric components are prevented from working in lower temperature environments for a long time. When the ambient temperature increases to raise the temperature in the cabinet 20, the elastic air bag 242 is heated and expanded to push the sliding block 241 to drive the rack 243 to move, the gear 246 meshed with the rack 243 rotates to enable the stop block to follow the rotation to open the air discharge window 232, and the higher the temperature is, the larger the thermal expansion of the elastic air bag 242 is, so that the larger the stop block rotation angle is, the larger the air discharge window 232 is opened, the air exchange rate inside and outside the cabinet 20 is accelerated, and the heat dissipation rate is accelerated to effectively cool the cabinet 20.
Compared with a power distribution cabinet with fixed size formed by welding and the like in the prior art, the invention has at least the following beneficial effects:
1, this scheme just can splice out the switch board of different specifications fast as required through stand and different quantity side veneer, and the assembly is simple, and scalability is strong.
2, the specifications of the side veneers and the stand columns are fixed, raw materials with different specifications do not need to be manufactured in advance, and the side veneers and the stand columns are convenient to process and high in replaceability.
3, clearance fit is between the adjacent connecting pieces of this scheme, and frictional force is little when pegging graft the concatenation, and grafting and dismantlement are fast.
4, this scheme is through setting up locking mechanism, through the shape closed mode that the physics blockked limiting between adjacent component in the horizontal direction removal, structural strength is high, and stability is good.
5, this scheme still has according to the circulation rate in the inside air current of switch board temperature automatically regulated switch board in order to keep warm or accelerate the heat dissipation, makes the electrical component in the switch board keep at suitable operating temperature, is favorable to prolonging the life of electrical component.
The foregoing is merely exemplary of the present invention, and specific structures and features that are well known in the art are not described in detail herein. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present invention, and these should also be considered as the scope of the present invention, which does not affect the effect of the implementation of the present invention and the utility of the patent. The protection scope of the present application shall be subject to the content of the claims, and the description of the specific embodiments and the like in the specification can be used for explaining the content of the claims.
