Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, and in particular to a high- and low-voltage electrical cabinet which is easy to install. Background Art

[0002] High and low voltage electrical cabinets are power distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets. Low voltage distribution cabinets are then led to distribution boards, control boxes and switch boxes for each power user. The equipment inside is a distribution device that is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.

[0003] In some fields, due to installation scenario or space limitations, high and low voltage electrical cabinets cannot be installed on the ground, so the high and low voltage electrical cabinets need to be fixed on the building surface at a certain distance from the ground.

[0004] Patent No. CN117458288B discloses a wall-mounted high and low voltage electrical cabinet that is easy to install. A mounting mechanism is arranged on the back of the electrical cabinet body, a synchronization mechanism is arranged on one side of the mounting mechanism, a clamping mechanism is arranged on one side of the synchronization mechanism, and the mounting mechanism includes an insertion frame, which is fixedly connected to the back of the electrical cabinet body, and an insertion seat is inserted into the inner side of the insertion frame. The present invention has the characteristics of strong practicality and easy installation. By providing a mounting mechanism, during the rotation connection process of the long screw rod, since the long screw rod and the second threaded block are threadedly connected, it will not be easily pulled out. Under the mutual sliding cooperation of the moving block and the convex slider, the moving block can be limited, and the stability of the moving block during movement is further improved. In the installation process, the staff does not need to use external tools to realize the installation of the device, which improves the operating efficiency of the electrical cabinet body during the installation process and enhances the practicality of the device.

[0051] Taking into account the complexity of the use environment of the electrical cabinet body 1, for example, when the electrical cabinet body 1 is used in a mine or a tunnel, since there is an inclination angle between the internal section or the installation surface of the mine or the tunnel and the ground, before installation, the auxiliary frame 2, the first installation and fixing component 3 and the second installation and fixing component 5 are still rotated 180 degrees with the first rotating shaft 14 as the axis, and then the first installation and fixing component 3 and the second installation and fixing component 5 are rotated clockwise by a corresponding angle with the second rotating shaft 32 as the axis, so that the first installation and fixing component 3 and the second installation and fixing component 5 can be parallel to the internal section or the installation surface of the mine or the tunnel, and have the characteristics of a wide range of applications.

[0052] See also Figure 7 and Fig.10, in an embodiment of the present invention, a sunken platform 15 is provided on the surface of the cabinet body 11, a semi-circular hole 17 is provided on the surface of the sunken platform 15, a limiting component 4 is arranged in the semi-circular hole 17, the limiting component 4 includes a limiting rod 41, a cam cover 42 and a return spring 43, the cam cover 42 is fixedly connected with the limiting rod 41, the return spring 43 is connected between the cam cover 42 and the semi-circular hole 17, and the limiting rod 41 penetrates through the semi-circular hole 17.

[0053] Please refer to Figure 6 , Figure 8 and Fig.10 , further, the first installation and fixing component 3 further includes a fixing frame 33 and a second limiting hole 34, the annular frame 31 is fixedly connected with the fixing frame 33, the fixing frame 33 is provided with the second limiting hole 34 on its surface, the first C-shaped frame 21 is provided with a first limiting hole 23 on its surface, and the centers of the limiting rod 41, the first limiting hole 23 and the second limiting hole 34 are aligned.

[0054] In the embodiment of the present invention, when the convex part of the cam cover 42 overlaps on the surface of the sunken platform 15, the limiting rod 41 disengages from the first limiting hole 23 and the second limiting hole 34. By rotating the cam cover 42, the convex part of the cam cover 42 is separated from the surface of the sunken platform 15. At this time, the cam cover 42 is located in the semi-circular hole 17, and the elastic force of the return spring 43 drives the limiting rod 41 to be located in the first limiting hole 23 and the second limiting hole 34.

[0055] Working principle: Step 1, taking the vertical building surface 7 as an example, first refer to Appendix Fig.11 and 12 , while pulling and rotating the cam cover 42 and the limiting rod 41, so that the convex part of the cam cover 42 overlaps on the surface of the sunken platform 15. At this time, the limiting rod 41 disengages from the first limiting hole 23 and the second limiting hole 34;

[0056] Step 2, refer to Appendix Fig.13 and 14 , rotate the auxiliary frame 2, the first installation and fixing component 3 and the second installation and fixing component 5 by 180 degrees with the first rotating shaft 14 as the axis, and adjust the heights of the first installation and fixing component 3 and the second installation and fixing component 5 according to the height of the skeleton 6 by the relative sliding between the first C-shaped frame 21 and the second C-shaped frame 22;

[0057] Step 3, refer to Appendix Fig.15 and 16 , rotate the first installation and fixing component 3 and the second installation and fixing component 5 clockwise by 180 degrees with the second rotating shaft 32 as the axis, so that the main fixing bolt 35 and the installation table 57 are facing the installation surface of the skeleton 6;

[0058] Step 4, refer to Appendix Fig.17, by moving the main body 1 of the electrical cabinet on the ground, the main fixing bolt 35 is aligned with the threaded hole at the center position of the skeleton 6, and by threading the main fixing bolt 35 on the surface of the skeleton 6, the pre-installation of the annular frame 31 is achieved, which is also convenient for the staff to carry out the next installation;

[0059] Step Five. To further improve the firmness of the installation, refer to the appendix Fig.18 , by rotating the adjusting gear 512 through the knob 511, the rotating adjusting gear 512 drives the transmission ring 52 to rotate around the axis of the fixed pin 37 through the toothed ring 53. The rotating transmission ring 52 uses the arc-shaped guide rail 54 to slidably connect with the movable pin 55 to control the movement rod 56 and the mounting table 57 to slide along the radial guide rail 36, so as to quickly align the three or four mounting tables 57 with the threaded holes at the remaining positions on the surface of the skeleton 6. The staff can fix the mounting table 57 to the skeleton 6 by using bolts or screws;

[0060] Step Six. Refer to the appendix Fig.19 and 20 , lift the main body 1 of the electrical cabinet upward. During this process, the first C-shaped frame 21 and the second C-shaped frame 22 can not only slide relative to each other, but also rotate around the second rotating shaft 32 and the first rotating shaft 14 respectively. Stop when the limit component 4 installed on the main body 1 of the electrical cabinet is aligned with the first limit hole 23 and the second limit hole 34. At this time, just gently rotate the cam cover 42 and the limit rod 41 to make the protruding part of the cam cover 42 disengage from the surface of the sunk platform 15. At this time, the elastic force of the return spring 43 can control the limit rod 41 to insert into the first limit hole 23 and the second limit hole 34, so as to fix the main body 1 of the electrical cabinet to the fixed frame 33, and then the main body 1 of the electrical cabinet can be installed at the skeleton 6 on the building surface 7, with good firmness.

[0061] When disassembly or maintenance is required, only need to move the limit rod 41 out of the first limit hole 23 and the second limit hole 34 by using the above operation method, and the main body 1 of the electrical cabinet can be easily and quickly placed on the ground stably.

[0062] In summary, through the structural design of matching the cabinet body 11 with the first rotating shaft 14, the auxiliary frame 2, the first installation and fixing component 3 and the second installation and fixing component 5, (1) by the relative sliding between the first C-shaped frame 21 and the second C-shaped frame 22 and rotating the auxiliary frame 2, the first installation and fixing component 3 and the second installation and fixing component 5 by 180 degrees around the first rotating shaft 14, the main fixing bolt 35 can be quickly adjusted to the specified installation height. Compared with the traditional method of using lifting equipment or manual lifting to the specified height for installation, it has the characteristics of not being restricted by the installation space and being convenient and labor-saving;

[0063] (2) After the main fixing bolts 35 are pre-installed on the frame 6, the staff can use the adjustment part 51 and the transmission ring 52 to simultaneously align the three or four groups of mounting platforms 57 with the threaded holes at other positions on the surface of the frame 6, which has the characteristic of being easy to quickly adjust the position of the mounting platform 57 according to the installation point;

[0064] (3) After the first mounting and fixing component 3 and the second mounting and fixing component 5 are fixed to the frame 6, the staff only needs to lift the electrical cabinet body 1 upwards. During the lifting process of the electrical cabinet body 1, the first U-shaped frame 21 and the second U-shaped frame 22 can slide relative to each other and rotate around the second rotating shaft 32 and the first rotating shaft 14 respectively. Therefore, it is easy to adjust the electrical cabinet body 1 to a vertical state. At this time, the first U-shaped frame 21 and the second U-shaped frame 22 can support the electrical cabinet body 1. Before further fixing the electrical cabinet body 1, there is no need to worry about the electrical cabinet body 1 tilting or falling. It has the characteristics of easy installation and good firmness.
