Description

Technical Field

[0001] The utility model belongs to the technical field of power supply boxes, and in particular relates to an emergency maintenance power supply box for electrical equipment. Background Art

[0002] The power supply box mainly provides operating power for vacuum circuit breakers and other high-voltage switches. The power supply box uses an input voltage of 220V or 380V, which is rectified by a thyristor voltage regulator, and outputs DC. It has the characteristics of outputting DC voltage with multiple gears and large current, or AC voltage, and performs single-open and single-close operations. During emergency maintenance of electrical equipment, the power supply box is often used to provide power because it is far away from the power supply or there is no available power supply.

[0003] After searching, the patent with authorization publication number CN218828647U discloses an outdoor portable mobile power box, including a power box, a control knob, an indicator light, a switch and a handle. A control knob is provided at the front end of the power box, an indicator light is provided on one side of the control knob, and a switch is provided on one side of the indicator light. A waterproof jacket is installed on the outer wall of the power box, a handle is installed on the top of the power box, a movable plate is provided at the bottom of the power box, and a movable wheel is connected to the bottom of the movable plate. A groove is provided inside the waterproof jacket, and a fan protective shell is installed on the outer wall of the back of the power box. The inner layer of the power box includes a metal explosion-proof outer shell, filling foam and an anti-static inner shell.

[0004] The above patent has the following shortcomings: although the power box has the function of being easy to move, the height of the power box is close to the ground and the chassis height cannot be adjusted. When driving on roads with stones or uneven surfaces, the device is easily stuck by obstacles, making it difficult to push and not convenient to move. At the same time, the device lacks a fixing mechanism for the power cord. When supplying power to other electrical equipment, a power cord is required to connect the two devices. If the power cord is accidentally pulled out during operation, the power supply will be disconnected, maintenance work will be affected, and work efficiency will be reduced. Utility Model Content

[0005] The utility model aims to provide an emergency maintenance power supply box for electrical equipment to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A fixed component is arranged on the outside of the box body near the power supply interface. The fixed component includes a fixed plate fixedly installed on one side of the power supply interface, a movable plate is movably installed on one side of the fixed plate, and a plurality of arc plates are fixedly installed on one side of the fixed plate and the movable plate, and the arc plates are arranged corresponding to the power supply interface.

[0011] Preferably, two adjustment frames are symmetrically installed on both sides of the bottom plate, a threaded rod is movably installed inside the adjustment frame through a bearing, a threaded block is installed on the outer side of the threaded rod through threaded engagement, and the threaded block is slidably fitted with the inner wall of the adjustment frame.

[0012] Preferably, a servo motor is installed on the top of the adjusting frame through a fixed seat, the output end of the servo motor is connected to the shaft of the threaded rod through a coupling, the threaded block is fixedly connected to the side away from the adjusting frame with an L-shaped rod, and the end of the L-shaped rod away from the threaded block is movably installed with a universal wheel through a bearing.

[0013] Preferably, a fixed plate is fixedly installed on the outside of the box body near the power supply interface, and a movable plate is movably installed on the outside of the box body near the fixed plate. The movable plate and the fixed plate are located on both sides of the power supply interface. Several arc plates are fixedly installed on the fixed plate and the movable plate near the power supply interface, and the arc plates are arranged corresponding to the power supply interface.

[0015] Preferably, a pull block is fixedly mounted on a side of the movable plate away from the fixed plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model provides adjustment frames on both sides of the bottom plate, and provides threaded blocks that can move up and down inside the adjustment frames. The threaded blocks are used to drive the L-shaped rod to move up and down, and then drive the universal wheels to move synchronously, so as to change the height of the bottom plate from the ground. When encountering stones or uneven roads, the bottom plate can be raised to prevent the bottom plate from hitting obstacles and causing the device to be unable to move forward. After the bottom plate is raised, the device can pass smoothly and move more conveniently. At the same time, the bottom plate drives the box to rise and fall, and can also supply power to electrical equipment at different heights. The device has wider adaptability and strong practicality.

[0018] (2) The utility model provides a fixed plate and a movable plate at the power supply interface. After the power cord is inserted into the power supply interface, the arc-shaped plates on both sides can be used to clamp the ends of the power cord, thereby achieving the purpose of limiting the position and preventing the power cord from moving away from the power supply interface. In this way, even if the power cord is pulled by mistake, it can prevent the power cord from being easily pulled out, thereby ensuring the stability of the power supply work, avoiding the power supply work from being affected, and ensuring work efficiency.

A universal wheel 26 is movably installed on one end of the L-shaped rod 25.

[0028] The fixing component 3 is arranged on the outside of the box body 1 near the power supply interface 11. The fixing component 3 includes a fixing plate 31 fixedly installed on one side of the power supply interface 11, and a movable plate 32 is movably installed on one side of the fixing plate 31. A plurality of arc plates 33 are fixedly installed on one side of the fixing plate 31 and the movable plate 32, and the arc plates 33 are arranged corresponding to the power supply interface 11.

[0029] Specifically, two adjustment frames 21 are symmetrically installed on both sides of the base plate 12, a threaded rod 22 is movably installed inside the adjustment frame 21 through a bearing, a threaded block 23 is installed on the outer side of the threaded rod 22 through threaded engagement, the threaded block 23 is slidably fitted with the inner wall of the adjustment frame 21, a servo motor 24 is installed on the top of the adjustment frame 21 through a fixed seat, the output end of the servo motor 24 is connected to the shaft transmission of the threaded rod 22 through a coupling, an L-shaped rod 25 is fixedly connected to the side of the threaded block 23 away from the adjustment frame 21, and a universal wheel 26 is movably installed on the end of the L-shaped rod 25 away from the threaded block 23 through a bearing.

[0030] As can be seen from the above, a threaded rod 22 is set inside the adjustment frame 21, and the threaded rod 22 is used to drive the threaded block 23 to move up and down inside the adjustment frame 21, thereby synchronously driving the L-shaped rod 25 and the universal wheel 26 to move, so as to change the height of the base plate 12 from the ground, and the servo motor 24 provides power output for the rotation of the threaded rod 22.

[0031] When in use, the servo motor 24 is started first, and the servo motor 24 drives the threaded rod 22 to rotate, and then the threaded block 23 is driven by the threaded rod 22 to move inside the adjustment frame 21 until the L-shaped rod 25 pushes the universal wheel 26 to lift the entire device. In this way, after the base plate 12 is raised, the device can pass smoothly and move more conveniently.

[0032] Embodiment 2:

[0033] See also Figure 1 and Figure 3As shown, a fixed plate 31 is fixedly installed on the side of the outside of the box body 1 close to the power supply interface 11, and a movable plate 32 is movably installed on the side of the outside of the box body 1 close to the fixed plate 31.
