Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, and in particular to a movable switch cabinet. Background Technology

[0002] Switchgear is a key piece of equipment in power installations used for power distribution, control, protection, and measurement. In many applications, such as construction sites, mines, or temporary power facilities, switchgear is required for flexible deployment and relocation according to construction progress or power demand. One of the core components of switchgear is the circuit breaker, which is responsible for circuit switching and fault protection. Because circuit breakers are high-frequency mechanical and electrical components, they inevitably require regular inspection, maintenance, or replacement after long-term operation to ensure the safety and stability of the entire power installation.

[0003] In existing switchgear, circuit breakers are typically mounted on internal mounting plates. When maintenance is required, personnel must penetrate deep into the cabinet and use tools to disassemble the numerous bolts or fasteners securing the mounting plates one by one. This disassembly and assembly method is not only cumbersome and time-consuming, but also extremely difficult, especially in the confined space and poor lighting of the cabinet. Furthermore, small parts such as bolts removed are easily lost.

[0004] This significantly reduces the maintenance efficiency of the switchgear and prolongs the power outage time. Especially in emergency repair scenarios, this slow maintenance method causes great inconvenience and makes it difficult to meet the flexible and efficient use requirements pursued by mobile switchgear. Therefore, a mobile switchgear is proposed to solve the above problems. Utility Model Content

[0005] In view of the problems of cumbersome, time-consuming and labor-intensive disassembly of the fixing plate during the inspection and maintenance of the internal circuit breaker in existing mobile switchgear, this utility model aims to provide a mobile switchgear with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a movable switch cabinet, including: a housing; a fixing plate, the fixing plate being detachably installed inside the housing; a circuit breaker, the circuit breaker being fixed to the fixing plate; and a quick-release mechanism.

[0007] The quick-release mechanism includes a base, which is fixed inside the housing; the quick-release mechanism also includes a sliding plate, which is slidably mounted on the base; the quick-release mechanism also includes a latch, which is fixed to the bottom of the fixed plate. When the latch is in the locked position, it is clamped by the base and the sliding plate together, thereby locking the fixed plate.

[0008] Furthermore, the quick-release mechanism also includes a spring, which is elastically disposed between the base and the sliding plate, and the spring tends to push the sliding plate to the unlocked position; the quick-release mechanism also includes a guide rod, which is fixed to the base, and a spring is sleeved on the guide rod, which provides guidance for the movement of the spring; the quick-release mechanism also includes a screw, which is threadedly connected to the base and abuts against the sliding plate, and the screw is used to overcome the elastic force of the spring and restrict the movement of the sliding plate when it is in the locked position.

[0009] Preferably, a movable switch cabinet further includes a base plate and a lifting mechanism. The lifting mechanism is disposed between the base plate and the outer casing. The lifting mechanism includes a lifting plate, which is movably disposed on the base plate. The outer casing is fixed on the lifting plate. The lifting mechanism is used to drive the outer casing and the lifting plate to lift as a whole.

[0010] Preferably, the lifting mechanism further includes a drive assembly for providing power to the lifting mechanism. The drive assembly includes a motor and a support plate, with the motor fixed to the base plate via the support plate.

[0011] Preferably, the drive assembly further includes a rotating shaft and a support base. The rotating shaft is driven to rotate by a motor, and the support base is used to provide stable and rotatable support for the rotating shaft to ensure smooth operation of the rotating shaft.

[0012] Preferably, the drive assembly further includes a connecting rod, a connecting column, and a connecting seat. The connecting rod is fixedly connected to the rotating shaft, the connecting column is rotatably connected to the connecting rod, the connecting seat is rotatably connected to the connecting column, and the connecting seat is fixedly connected to the bottom of the lifting plate. The structural combination is used to convert the rotational motion of the rotating shaft into the vertical lifting motion of the lifting plate.

[0013] Preferably, the lifting mechanism further includes a slide rail and a slider. The slide rail is vertically fixed to the base plate, and the slider is fixed to the lifting plate. The slider is slidably connected inside the slide rail, and the slide rail guides the movement of the slider to ensure that the lifting plate is raised and lowered smoothly.

[0014] Preferably, the slide rail is stably connected to the base plate by a fixing seat, which enhances the rigidity of the connection between the slide rail and the base plate.

[0015] Preferably, the lifting mechanism further includes a limiting plate, which is fixed to the top of the slide rail. The limiting plate is used to limit the slider when the lifting plate moves to the highest position, so as to prevent the slider from falling off the slide rail.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of cumbersome, time-consuming and labor-intensive disassembly of the internal fixing plate of the switch cabinet in the prior art by setting a quick-release mechanism consisting of a base, a sliding plate, a buckle, a spring and screws. It achieves the technical effect of quickly disassembling the circuit breaker fixing plate by the operator only needing to loosen the screws, and the sliding plate can move under the action of the spring to release the buckle, which greatly improves the convenience and flexibility of maintenance.

[0017] 2.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Reference Figures 1 to 5 This utility model provides a movable switch cabinet, which aims to solve the problem of difficulty in adjusting the height of the switch cabinet when it is moved to an uneven site in the prior art.

[0023] A movable switchgear includes a base plate 26, a lifting mechanism 2 mounted on the base plate 26, and a housing 1 fixed to the lifting mechanism 2. A fixing plate 4 is detachably installed inside the housing 1, and a circuit breaker 3 is fixed on the fixing plate 4. The movable switchgear also includes a quick-release mechanism 5 for quickly removing the fixing plate 4. The quick-release mechanism 5 includes: a base 51 fixed inside the housing 1; a sliding plate 52 slidably mounted on the base 51; and a latch 54. The buckle 54 is fixed to the bottom of the fixed plate 4, and the buckle 54 is held by the base 51 and the sliding plate 52 when it is locked; the spring 55 is elastically disposed between the base 51 and the sliding plate 52, and the spring 55 tends to push the sliding plate 52 to the unlocked position; the guide rod 56 is fixed to the base 51, and the spring 55 is sleeved on the guide rod 56; and the screw 53 is threaded to the base 51 and abuts against the sliding plate 52, and the screw 53 is used to restrict the movement of the sliding plate 52 in the locked position.

[0024] The lifting mechanism 2 includes a lifting plate 21, and the outer shell 1 is fixed to the lifting plate 21. The lifting mechanism 2 also includes a slide rail 23, which is vertically fixed to the base plate 26. The slide rail 23 is stably connected to the base plate 26 through a fixing seat 25. The lifting mechanism 2 also includes a slider 22, which is fixed to the lifting plate 21 and slidably connected to the slide rail 23. Through the sliding cooperation structure between the slider 22 and the slide rail 23, it is ensured that the lifting plate 21 can only move stably in the vertical direction during the lifting process. The lifting mechanism 2 also includes a limiting plate 24, which is fixed to the top of the slide rail 23 to prevent the slider 22 from falling off the slide rail 23.

[0025] The lifting mechanism 2 also includes a drive assembly 27, which is used to drive the lifting plate 21 to rise and fall. The drive assembly 27 includes a motor 271 and a support plate 272. The motor 271 is fixed to the base plate 26 through the support plate 272. The drive assembly 27 also includes a rotating shaft 274 and a support seat 273. The rotating shaft 274 is driven to rotate by the motor 271, and the support seat 273 is used to rotate and support the rotating shaft 274. The drive assembly 27 also includes a connecting rod 275, a connecting column 276, and a connecting seat 277. The connecting rod 275 is fixedly connected to the rotating shaft 274. The connecting column 276 is rotatably connected to the connecting rod 275. The connecting seat 277 is rotatably connected to the connecting column 276 and is fixedly connected to the bottom of the lifting plate 21. When the motor 271 drives the rotating shaft 274 to rotate, it causes the connecting rod 275 to swing. The connecting rod 275 pushes the lifting plate 21 to rise and fall vertically along the slide rail 23 through the connecting column 276 and the connecting seat 277.

[0026] In a preferred embodiment, a movable switch cabinet further includes a base plate 26 and a lifting mechanism 2; the lifting mechanism 2 includes a lifting plate 21, which is movably mounted on the base plate 26, and the outer casing 1 is fixed on the lifting plate 21. The lifting mechanism 2 also includes a drive assembly 27, which includes a motor 271 and a support plate 272. The motor 271 is fixed on the base plate 26 via the support plate 272. The drive assembly 27 also includes a rotating shaft 274 and a support base 273. The rotating shaft 274 is driven to rotate by the motor 271, and the support base 273 is used to rotate and support the rotating shaft 274.

[0027] In a preferred embodiment, the lifting mechanism 2 further includes: a slide rail 23, which is vertically fixed on the base plate 26; and a slider 22, which is fixed on the lifting plate 21 and slidably connected to the slide rail 23. The slide rail 23 is stably connected to the base plate 26 through a fixing seat 25.

[0028] The implementation principle of this application embodiment is as follows: The movable switch cabinet is composed of a fixed plate 4 installed inside the housing 1, a quick-release mechanism 5, a circuit breaker 3, and a lifting mechanism 2 installed at the bottom of the housing 1 in sequence. The lifting mechanism 2 can adjust the height of the housing 1, and the fixed plate 4 can be disassembled through the quick-release mechanism 5, which facilitates the maintenance of the circuit breaker 3 by the staff.

[0029] On an uneven mountainous construction site, the switchgear needs to be adjusted to a suitable height to meet the connection requirements of electrical equipment. Motor 271 is fixed to base plate 26 via support plate 272. When the operator activates drive assembly 27, motor 271 drives shaft 274 connected to its output end to rotate. Two support seats 273 provide stable support for shaft 274. A connecting rod 275 is fixedly connected to shaft 274, rotatably connected to connecting column 276. Connecting column 276 is rotatably connected to connecting seat 277, which is fixedly connected to the bottom of lifting plate 21. The rotation of shaft 274 causes connecting rod 275 to rotate around the axis. This, in turn, drives the connecting column 276, increasing the angle between the connecting column 276 and the connecting rod 275, thereby lifting the connecting seat 277 and the lifting plate 21. Simultaneously, sliders 22 are connected to the four corners of the lifting plate 21, and the four sliders 22 move up and down on the slide rail 23. The limiting plate 24 limits the movement to prevent the lifting plate 21 from detaching. The slide rail 23 is stably connected to the base plate 26 through the fixed seat 25, thereby ensuring the stability of the lifting plate 21 in the horizontal direction. In various complex terrains and workplaces, the lifting mechanism 2 can quickly and conveniently realize the height adjustment of the switchgear, meet different installation and use requirements, and expand the application range of the switchgear.

[0030] After a period of use, the circuit breaker 3 inside the switchgear needs to be inspected. Workers can disassemble the fixing plate 4 via the quick-release mechanism 5 to facilitate inspection of the circuit breaker 3. In the initial state, the base 51 is fixed inside the outer casing 1 and works with the sliding plate 52 to stably clamp the buckle 54. The buckle 54 is fixed to the bottom of the fixing plate 4. In this position, the screw 53 is tightened, and the spring 55 between the sliding plate 52 and the base 51 is compressed and sleeved on the guide rod 56. Workers only need to gently twist the screw 53 to release the restriction. The sliding plate 52 moves under the action of the spring 55, and the originally locked buckle 54 loosens. Then, the fixing plate 4 can be pulled out, allowing for convenient inspection and maintenance of the circuit breaker 3. The operation is simple and quick, greatly improving the flexibility of switchgear maintenance and operation, reducing maintenance difficulty and cost, making maintenance work more convenient and faster, reducing the time and labor costs required for maintenance, and improving equipment availability.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
