Detailed Description

The present invention will be further explained with reference to the drawings and examples.

The utility model discloses a temporary power distribution cabinet for outdoor construction, as shown in fig. 1 to 5, including a cabinet body 1, a rectangular bottom plate 2 is arranged below the cabinet body 1, rollers 3 are arranged at two ends of the bottom plate 2, through holes are arranged at four corners of the bottom plate 2, a grounding stud 4 in clearance fit with the through holes is arranged in the through holes, and a first locking nut 5 in threaded fit with the grounding stud 4 is arranged on the grounding stud 4 above the bottom plate 2; the cabinet body 1 is arranged on the bottom plate 2, and a damping mechanism is arranged between the cabinet body 1 and the bottom plate 2.

The cabinet body 1 includes metal casing and inside electrical equipment, and electrical equipment sets up according to the construction demand can. The cabinet body 1 is rectangular, so the bottom plate 2 is a rectangular bottom plate and is matched with the cabinet body 1 in shape. The bottom plate 2 is made of a metal plate, such as an iron plate, having a thickness of not less than 12mm to ensure sufficient strength.

For the convenience of promoting the removal of interim switch board, the both ends of bottom plate 2 bottom are provided with a pair of gyro wheel 3 respectively, and gyro wheel 3 can adopt the universal wheel to turn round when removing. The roller 3 is arranged below the bottom plate 2 through a bracket. In addition, one end of the bottom plate 2 is provided with a hand push rod 13, and the bottom plate 2 can be pushed to move by the hand push rod 13, so that the cabinet body 1 is driven to move. Of course, power equipment such as a motor can be adopted to drive the rotating shaft to rotate, the cabinet body 1 can be moved more laborsavingly, the structural complexity of the temporary power distribution cabinet can be increased, and the manufacturing cost is higher.

At the in-process that uses interim switch board, if only rely on gyro wheel 3 to support whole interim switch board, because gyro wheel 3 rolls easily, stability is relatively poor. Therefore, the utility model discloses set up a vertical ground connection double-screw bolt 4 respectively at four angles of bottom plate 2, remove interim switch board to the destination after, can squeeze into the underground with ground connection double-screw bolt 4 to utilize first lock nut 5 with bottom plate 1 and ground connection double-screw bolt 4 fastening connection, can guarantee the stability of bottom plate 2 and the cabinet body 1, prevent interim switch board automatic movement, improve the security.

In addition, ground stud 4 adopts electrically conductive metal material, like the iron prop etc. first lock nut 5 and bottom plate 2 also electrically conduct, and the cabinet body 1 is connected the back with bottom plate 2, and cabinet body 1 is promptly indirect and ground stud 4 electrically conductive connection, and when the electric leakage appeared in the cabinet body 1, the electric current can be transmitted to ground stud 4 to there is ground stud 4 to lead to underground, prevents that the staff from electrocuting. In addition, after installation, the grounding stud 4 can be connected with the shell of the cabinet 1 by adopting a conducting strip.

It can be seen that, the utility model discloses an after interim switch board installation is fixed, need not additionally to set up the earth connection, improved the convenience of using. In order to ensure the effectiveness of grounding, the length of the grounding stud 4 is 1.2-1.5 m, and insulating paint can be coated on the upper part of the grounding stud 4, wherein the length of the coated insulating paint is about 1/3 of the total length of the grounding stud 4, so that electric charge is ensured to be introduced into the ground, and workers on the ground are prevented from getting electric shock.

The cabinet body 1 can be mounted on the bottom plate 2 in various conventional manners, preferably, as shown in fig. 5, the bottom of the cabinet body 1 is provided with a plurality of vertical supporting legs 10, the upper ends of the supporting legs 10 can be welded on the bottom of the cabinet body 1, the lower ends of the supporting legs 10 penetrate through the bottom plate 2, and the lower ends of the supporting legs 10 are provided with third locking nuts 11. This kind of mounting means, after the construction is accomplished, can pull down the cabinet body 1 from bottom plate 2 fast to in with cabinet body 1, bottom plate 2 and ground connection stud 4 transport to other construction sites and use again.

In order to prevent that the in-process cabinet body 1 that removes interim switch board from producing great vibrations, the utility model discloses set up damper between the cabinet body 1 and bottom plate 2, specifically, damper is spring 12, and the supporting legs 10 of bottom plate 2 top is set up to the 12 covers of spring is outer. In addition, the springs 12 may also be multiple, and are not sleeved on the supporting feet 10, but are uniformly arranged between the cabinet body 1 and the cabinet body 1.

Because the cabinet body 1 height of interim switch board generally is 1.5 to 1.8m, highly great, the focus is higher, is difficult to the steadiness at the in-process that removes, consequently, in order to improve the security of the cabinet body 1, as shown in fig. 1 and fig. 2, the utility model discloses intermediate position at 2 edges of bottom plate is provided with vertical bumping post 6, and the top of bumping post 6 is provided with the constant head tank, is provided with horizontally crossbeam 7 in the constant head tank, and crossbeam 7 is run through to the upper end of ground connection double-screw bolt 4, and is equipped with on the ground connection double-screw bolt 4 of crossbeam 7 top and below with ground connection double-screw bolt 4 screw-thread fit's second lock nut 8.

The bumping post 6 adopts the metal cylinder, such as section bar such as channel-section steel, and 6 lower extremes of bumping post can weld on bottom plate 2. The cross beam 7 can also adopt sectional materials such as channel steel, and the two ends of the cross beam 7 are provided with positioning holes. When the temporary power distribution cabinet needs to be moved, the grounding stud 4 is upwards pulled out of the ground, the crossbeam 7 is placed into the positioning groove, the upper end of the grounding stud 4 penetrates through the positioning hole in the end part of the crossbeam 7, the crossbeam 7 and the grounding stud 4 are locked by the second locking nut 8, meanwhile, the lower end of the grounding stud 4 is provided with a fourth locking nut, and the fourth locking nut is matched with the first locking nut 5, so that the lower end of the grounding stud 4 is stably connected with the bottom plate 2. The cross beam 7 can be used as a guardrail to protect the cabinet body 1.

In order to improve the protection effect, the lateral surface of the crossbeam 7 facing the cabinet body 1 is provided with an elastic pad 9, and the elastic pad 9 can be made of elastic materials such as rubber and silica gel, has larger thickness and can be best pressed and contacted with the cabinet body 1.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
