Description

Technical Field

[0001] The utility model relates to the technical field of power boxes, and more specifically, to a power box for electric power engineering. Background Art

[0002] The power box is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the terminal equipment of the power distribution system. Distribution cabinet is also the general term for motor control center. Distribution cabinet is used in the occasions with dispersed load and fewer circuits, and motor control center is used in the occasions with concentrated load and more circuits. They distribute the electric energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load, which is collectively referred to as power distribution center. The terminal distribution equipment is collectively referred to as lighting power distribution box. They are far away from the power supply center and are dispersed small-capacity distribution equipment. At present, the small distribution boxes used for power engineering management are mainly installed on the wall.

[0003] For example, a power box for electric power engineering with publication number CN215911787U belongs to the technical field of power boxes. A power box for electric power engineering includes a cabinet, and also includes: a first terminal and a second terminal, which are fixedly connected in the cabinet; an outer shell, which is fixedly connected to the inner wall of the cabinet; the outer shell is symmetrically designed, and the two outer shells are respectively placed at the lower end of the first terminal and the lower end of the second terminal, and a clamping mechanism is provided on the outer shell, and a box body is provided between the first terminal and the second terminal, and a line changing mechanism is provided in the box body; the utility model has a simple structure and is easy to operate. The power-on direction is changed by turning the dial head to turn the dial, which is convenient for replacing damaged electrical components. The power box does not need to be powered off, ensuring that other electrical components can work normally.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device can be operated conveniently to a certain extent, in actual use, some large power boxes may be difficult to adjust their position and height during installation due to their large size and weight, which may affect the installation efficiency to a certain extent.

[0005] Therefore, in view of the above problems, a power box for electric power engineering is proposed. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a power box for electric power engineering, which has the advantages of convenient height adjustment and replacement of installation position.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric power box for electric power engineering, comprising a support frame, a fixed plate fixedly connected to the bottom of the support frame, a hydraulic cylinder fixedly installed in the middle position of the bottom of the fixed plate, a fixed box movably connected to the bottom of the hydraulic cylinder, a movable roller movably installed inside the fixed box, ear plates fixedly installed on both sides of the fixed box, a limit rod movably connected to the inner side of the ear plate, a lower touch plate fixedly installed on the bottom of the limit rod, jacks fixedly installed at the four corners of the bottom of the fixed plate, the output end of the jack is movably connected to the lower touch plate, and a stabilizing plate is fixedly installed on the top of the jack.

[0008] As a preferred technical solution of the utility model, a cabinet is fixedly installed on the inner side of the top of the support frame, and a protective door is movably installed on the front of the cabinet.

[0009] As a preferred technical solution of the utility model, a transparent window is provided on the surface of the protective door, and a pull ring is fixedly installed on one side of the transparent window.

[0010] As a preferred technical solution of the utility model, an insulating bottom plate is installed at the bottom of the inner cavity of the cabinet through insulating pins, and a main power switch is fixedly installed on the surface of the insulating bottom plate.

[0011] As a preferred technical solution of the utility model, short-circuit protectors are fixedly installed on both sides of the main power switch, and a conductive bus is fixedly installed on the bottom of the main power switch.

[0012] As a preferred technical solution of the utility model, a shunt circuit breaker is fixedly installed at the bottom of the conductive busbar, and a contactor is fixedly installed at the bottom of the shunt circuit breaker.

[0013] As a preferred technical solution of the present utility model, a junction box is fixedly installed at the bottom of the inner cavity of the cabinet, and a wire harness tube is fixedly installed on the front of the junction box.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model facilitates the lifting and fixing of the overall power box cabinet by setting a support frame, and facilitates the provision of an installation site for the hydraulic cylinder and the jack by setting a fixed plate. The hydraulic cylinder can control the up and down movement of the fixed box, and the jack facilitates the user to adjust the installation height of the overall power box. When the installation position of the power box needs to be changed, the fixed box can be controlled to descend by the hydraulic cylinder so that the moving roller inside it contacts the ground. At this time, the stabilizing plate is controlled to separate from the ground by the jack, thereby greatly reducing the friction between the overall device and the ground, so that the device has the ability to move. When the position of the overall device needs to be fixed, the above operation can be performed in reverse. The lower touch plate and the limit rod can ensure that the jack rises and the fixed box falls with a certain threshold, thereby preventing them from falling too much and causing the integrity of the overall device to be reduced.

[0016] 2. The utility model provides an installation site for the insulating base plate and its related structures through the setting of the cabinet, provides appropriate protection for the cabinet through the setting of the protective door, and facilitates users to observe the relevant conditions inside the cabinet from the outside through the setting of the transparent window. The setting of the pull ring facilitates users to open the protective door. The setting of the insulating base plate can enhance the safety of the overall power box. The short-circuit protector is an integral protection structure that provides power-on and power-off protection for the overall power box. The setting of the branch circuit breaker facilitates separate protection of the wiring related to a single contactor. The setting of the contactor facilitates the connection between the overall power box and external equipment. The setting of the wire bundle tube facilitates the proper bundling of internal wires to prevent them from being too messy. BRIEF DESCRIPTION OF THE DRAWINGS
