DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1 The utility model provides a prefabricated substation, including a substation body 1 and a quick assembly structure 2. The quick assembly structure 2 is arranged at the bottom of the substation body 1.

[0023] See also Figure 2-6The quick assembly structure 2 in the utility model includes a base 21, an installation slot 22, a connecting frame 23, a No. 1 installation hole 24, a notch 25, a threaded hole 26, a receiving through hole 27, a connecting frame 28, a screw 29, a nut 210, a positioning pin 211 and a No. 2 installation hole 212. The substation body 1 is centrally arranged on the top of the base 21. The top surface of the base 21 is provided with an installation slot 22. The installation slots 22 are connected end to end to form a rectangular shape. A connecting frame 23 is welded at the bottom end of the substation body 1, and the connecting frame 23 can be longitudinally inserted into the inner side of the installation slot 22, so that the substation body 1 and the base 21 are initially connected and fixed. The left and right side walls of the connecting frame 23 are horizontally penetrated with No. 1 installation holes 24, and the left and right side walls of the base 21 are provided with notches 25. The side wall of the notch 25 is provided with a threaded hole 26 in the middle, and the side wall of the notch 25 is symmetrically provided with receiving through holes 27 at the front and rear ends. The threaded holes 26 and the receiving through holes 27 The screw 29 is rotatably mounted on the middle of the inner side of the connecting frame 28, and the head end of the screw 29 penetrates the outer side of the connecting frame 28 and is connected and fixed with the nut 210. The rotation of the screw 29 is controlled by the nut 210. The front and rear ends of the inner side of the connecting frame 28 are symmetrically distributed and fixed with positioning pins 211. The left and right side walls of the installing slot 22 are provided with No. 2 installing holes 212. The screw 29 passes through the inner side of the threaded hole 26 and is threadedly connected thereto, and the screw 29 can be linearly inserted through the No. 1 installing hole 24 and then inserted into the inner side of the No. 2 installing hole 212. The positioning pin 211 is slidably inserted into the inner side of the receiving through hole 27, and the positioning pin 211 can be linearly inserted through the No. 1 installing hole 24 and then inserted into the inner side of the No. 2 installing hole 212, thereby locking the connecting frame 23 to the inner side of the installing slot 22, thereby realizing the connection and fixation between the substation body 1 and the base 21.

[0024] To further explain, no less than four positioning pins 211 are installed on the connection frame 28 , and all the positioning pins 211 are symmetrically distributed at the front and rear parts of the connection frame 28 to ensure the connection strength between the substation body 1 and the base 21 .

[0025] To further illustrate, when the connecting frame 23 is fully inserted into the inner side of the installation slot 22, the No. 1 installation hole 24 will be directly opposite to the location of the No. 2 installation hole 212, which is quick to locate and facilitates rapid subsequent operations.

[0026] It is further explained that the depth of the installation slot 22 is greater than the height of the connection frame 23 to ensure that the substation body 1 can be completely placed on the top of the base 21, so that the base 21 provides stable support for the substation body 1.

[0027] To further illustrate, the maximum plug-in length between the positioning pin 211 and the second mounting hole 212 is not less than 5 cm, so as to ensure that the positioning pin 211 and the second mounting hole 212 have sufficient connection length to ensure the stability of the connection.

[0028] Further explanation: a rubber pad is laid on the edge of the top surface of the base 21, and the thickness of the rubber pad is not less than 1 cm. The rubber pad can fill the gap between the substation body 1 and the base 21, so that the substation body 1 is stably installed and not easy to shake.

[0029] Here’s how it works:

[0030] First, before installing the substation body 1, first use a wrench to reversely turn the nut 210 to control the rotation of the screw 29, so that the screw 29 is screwed outward along the threaded hole 26 until the positioning pin 211 leaves the installation slot 22 and retracts into the inner side of the receiving through hole 27, so that the connecting frame 23 can be inserted into the inner side of the installation slot 22 without hindrance, thereby completing the pre-installation preparation work.

[0031] Second, when installing the substation body 1, the substation body 1 is lifted and placed on the top of the base 21 by external lifting equipment, and the connecting frame 23 is longitudinally inserted into the inner side of the installation slot 22, so that the substation body 1 and the base 21 are initially connected and fixed, and then the nut 210 is turned forward with a wrench to control the rotation of the screw 29, so that the screw 29 is screwed inward along the threaded hole 26 into the inner side of the installation slot 22 until the connecting frame 28 is completely engaged with the inner side of the slot 25. During this process, the screw 29 and the positioning pin 211 will pass through the No. 1 installation hole 24 in a straight line and then be inserted into the inner side of the No. 2 installation hole 212, thereby locking the connecting frame 23 on the inner side of the installation slot 22, thereby completing the installation and fixation of the substation body 1 and the base 21, which is convenient to install and reduces repeated operation processes to improve work efficiency.

[0032] Third, when the substation body 1 needs to be disassembled, use a wrench to reversely turn the nut 210 to control the rotation of the screw 29 until the screw 29 and the positioning pin 211 leave the inner side of the installation slot 22 to release the lock on the connecting frame 23. Then, the substation body 1 can be lifted off the top of the base 21 by an external lifting device, thereby completing the disassembly of the substation body 1 and the base 21. The disassembly is convenient, and repeated operation processes are reduced to improve work efficiency.

[0033] The utility model provides a prefabricated substation, which is provided with a quick assembly structure 2 at the bottom of the substation body 1, and the substation body 1 is lifted and placed on the top of the base 21 by an external lifting device, so that the connecting frame 23 is longitudinally inserted into the inner side of the installation slot 22, and then the nut 210 is turned forwardly by a wrench to control the rotation of the screw rod 29, so that the screw rod 29 and the positioning pin 211 are inserted through the No. 1 installation hole 24 and then inserted into the inner side of the No. 2 installation hole 212, and then the connecting frame 23 is locked in the inner side of the installation slot 22, thereby completing the installation and fixation of the substation body 1 and the base 21. When disassembling the substation body 1, the nut 210 is turned in the opposite direction by a wrench to control the rotation of the screw rod 29 to release the lock of the connecting frame 23, and then the substation body 1 can be lifted off from the top of the base 21 by an external lifting device, thereby completing the disassembly of the substation body 1 and the base 21, and the disassembly and assembly are convenient, and repeated operation processes are reduced to improve work efficiency.
