[0109] In summary, a more specific implementation manner of the present utility model is as follows:

[0110] Before using a new type of convenient plug-and-play temporary power switch box with the above design structure, it needs to be installed for standby.

[0111] Installation steps of the support frame 1:

[0112] Step 1, the operator places the reverse side of the support frame 13, which is the side to be installed with the switch box, horizontally on the ground at any position within a radius of 3 meters from the power-consuming equipment at the construction site; Step 2, place the upper end of the vertical support leg 11 at the inner edge of the short side direction of the support frame 13 so that the connecting holes and the corresponding through holes are aligned; Step 3, connect the aligned sets of connecting holes and through holes through the locking assembly 14 and tighten the bolts; Step 4, place the reinforcing cross bar 12 in the middle of the support frame 1, align the mounting holes at both ends of the reinforcing cross bar 12 with the connecting holes of the second connecting rod, and then connect them through the locking assembly 14 and tighten the bolts; Step 5, turn the entire support frame 1 over so that the front side of the support frame 13 faces up. At this time, the installation of the support frame 1 is completed.

[0113] Installation of the switch box 2

[0114] Step 1, the operator places the bottom of the box body 21 on the upper surface of the support frame 13; Step 2, the operator aligns the reserved nuts at the bottom of the box body with the oblong connecting holes of the support frame rectangular frame; Step 3, the operator passes the connecting piece 3 through the oblong connecting hole and tightens it with the reserved nut 22, and the installation of the switch box 2 and the support frame 1 is completed.

[0115] Connect the power supply

[0116] Step 1: The operator passes the main cable upward through the inside of the support frame 1 and the bottom of the box body 21 and into the box body 21 to connect with the main switch breaker of the breaker group 23. Step 2: The operator closes the main switch breaker. At this time, it can be judged whether there is power supply through the working indicator light 6. Step 3: The operator inserts the plug of the electrical equipment end into the corresponding numbered socket of the socket group 24. Step 4: The operator closes the corresponding numbered branch breaker. At this time, it can be judged whether there is power supply through the power-on indicator light 28, so that the equipment can be powered on and used.

[0117] After specific use, if removal is required, the specific removal steps are as follows:

[0118] The entire disassembly process repeats the above installation process in reverse and follows the principle of "the last installed is the first to be removed, and the first installed is the last to be removed".

[0119] During use, when the operator is using electricity, the operator does not need to open the normally closed box door 25. Just insert the electrical wire at the power-using end into the corresponding socket on the socket group 24 to use. At the same time, when operations such as power-on and power-off are required, just open the self-locking protective cover 26 to operate. To a certain extent, it avoids the leakage and electric shock safety risks of unauthorized wiring and ensures that the electrical equipment meets the regulations of one machine, one switch, and one leakage protector. The outer shells of the sockets are all coated with corresponding color paints, which can visually distinguish the rated voltage, clearly mark the specific parameters, and at the same time are provided with corresponding power indicator lights to accurately judge whether the socket is in a live state through the indicator lights.

[0120] During the use process, after the operator opens the normally closed box door 25, the operator can view or record the daily inspection record form in the data box 5 or store inspection documents.

[0121] At the same time, during the above implementation operation process, in order to solve the technical problems of being light and easy to carry and saving materials to reduce costs, the thickness of the above box body can be optimized from the original 200 mm to 160 mm, achieving two goals: one is to save production materials and reduce costs; the other is to reduce the self-weight and facilitate manual handling during the use process. At the same time, the opening and closing direction of the box door is set at the position of the power cable inlet on the left side of the box body, so that the protruding structure inside the door lock shares the same space with the cable, effectively solving the collision problem. The purpose of this design change in the position of the box body is to solve the technical problem that due to the compression of the external dimensions of the box body, the internal space is compact, resulting in a collision between the internal structure of the door lock and the electrical components inside the box and the inability to effectively close.

[0122] The above has introduced in detail what the present utility model provides. The principle of the present utility model has been described herein. The description of the above working principle is only used to help understand the core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
