Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet devices, in particular to a power control cabinet for power engineering. Background Art

[0002] Power control cabinets are common power distribution equipment in power engineering. The interior of the power control cabinet is mostly modules with various electronic components. To ensure the safe use of these modules, the cabinet generally needs to be sealed and protected by a cabinet door.

[0003] However, during the current installation of power projects, the locks of the distribution cabinet doors are generally exposed to the outside, or the lock holes are exposed to the outside. The power project installation site is crowded with people, and the component modules inside the power control cabinet are of high value, which makes it easy for idle people in society to covet them and destroy the locks for theft. In addition, the power project construction site is relatively complex, and if the locks of the distribution cabinet are exposed to the outside and opened by accidental collision, there will be certain safety risks. Therefore, this application specially proposes a power control cabinet for power projects to solve the above problems. Utility Model Content

[0007] Preferably, a support rod is fixedly connected to the inner wall of the cabinet, and a clamping sleeve for clamping the mounting sleeve is integrally arranged on the support rod.

[0008] Preferably, a limit plate used in conjunction with the cabinet door is fixedly connected to the inner wall of the cabinet body, and a handle is fixedly connected to the front end of the cabinet door.

[0009] The beneficial effects of the utility model are:

[0010] When the present application is in use, the internal locking device and the limit sleeve are built into the cabinet body, and the controller can be operated by the remote control switch to control the power on and off of the electromagnet. When the electromagnet is in the power-on state, it has a strong magnetism and is adsorbed with the armature, so that the lock rod is plugged into the limit sleeve, and the cabinet door is restricted and cannot be opened; when the electromagnet is in the power-off state, the electromagnet loses its magnetism and separates from the armature, and the lock rod will also be separated from the limit sleeve, so that the cabinet door can be opened normally. The internal locking device and the limit sleeve of the present application are built into the cabinet body, and there is no need to be equipped with a key or to open a lock hole on the cabinet door, which avoids the risk of the lock and the lock hole being exposed to the outside and being stolen by social idlers, and avoids the risk of the lock being exposed to the outside and being damaged when the working conditions on the construction site are complex.

[0018] The following is combined with Figure 1-5 The specific implementation methods of the present invention are further described in detail.

[0019] In the embodiment 1, the technical solution is that when the present application is in use, the internal locking device 9 and the limiting sleeve 6 are built into the cabinet 1, and the controller 7 can be operated by the remote control switch to control the power on and off of the electromagnet 15. When the electromagnet 15 is in the power-on state, it has a strong magnetism and is attracted to the armature 8, so that the locking rod 11 is inserted into the limiting sleeve 6, and the cabinet door 4 is restricted and cannot be opened; when the electromagnet 15 is in the power-off state, the electromagnet 15 loses its magnetism and separates from the armature 8, and the locking rod 11 will also be separated from the limiting sleeve 6, so that the cabinet door 4 can be opened normally. The internal locking device 9 and the limiting sleeve 6 of the present application are built into the cabinet 1, and no key is required or a lock hole is opened on the cabinet door 4, which avoids the risk of the lock and the lock hole being exposed to the outside and being stolen by social idlers, and avoids the risk of the lock being exposed to the outside and being damaged when the work site is complex.

[0020] Example 2, based on Example 1, specifically, when in use, the remote control switch can remotely control the controller 7 from a certain distance, thereby energizing or de-energizing the electromagnet 15. The specific principle of this invention can be based on existing technology and will not be described in detail in this application. The remote control switch is controlled by the relevant personnel responsible for factory power to ensure safety.

[0021] Under normal circumstances, as shown in the accompanying drawings Figure 2 As shown, the controller 7 controls the electromagnet 15 to be in an energized state and to have a strong magnetism, so that the electromagnet 15 and the armature 8 on the short rod 5 are in an adsorption state. At this time, the locking rod 11 is inserted into the limiting sleeve 6, and the cabinet door 4 is restricted to the door opening 2 of the cabinet body 1 and cannot be opened. The spring 13 is also in a stretched state. The cabinet door 4 of the present application is mounted on the cabinet body 1 via the hinge 3 to facilitate opening and closing.

[0022] When it is necessary to open the cabinet door 4 for maintenance work, the controller 7 is operated by the remote control switch to cut off the power to the electromagnet 15 on the support plate 14, so that the electromagnet 15 loses its magnetism. The electromagnet 15 loses its magnetism and will no longer have an adsorption effect with the armature 8, and the spring 13 will automatically contract and drive the locking rod 11 to move downward along the installation sleeve 10, so that the locking rod 11 will be separated from the limit sleeve 6. When the locking rod 11 is separated from the limit sleeve 6, the cabinet door 4 loses its restriction and can be opened normally; when the maintenance is completed and the cabinet door 4 is locked again, the cabinet door 4 is closed first, and the cabinet door 4 is closed so that the cabinet door 4 is pressed against the limit plate 20 to ensure that the cabinet door 4 is closed in place. The operator operates the controller 7 through the remote control switch, so that the controller 7 controls the electromagnet 15 to be energized and has a strong magnetism. The electromagnet 15 has magnetism and will be attracted by the armature 8, so that the electromagnet 15 moves upward together with the support plate 14, and then the locking rod 11 in the installation sleeve 10 will also move upward with the support plate 14. The locking rod 11 moves upward to insert into the limit sleeve 6. The upper end of the locking rod 11 is provided with a large rounded corner 12 to facilitate its insertion into the limit sleeve 6. When the electromagnet 15 moves upward until the electromagnet 15 is tightly combined, it stops moving. At this time, the locking rod 11 and the limit sleeve 6 are matched, and the cabinet door 4 is restricted. At this time, the spring 13 is also stretched as shown in the accompanying drawings of the specification. Figure 2 The mounting sleeve 10 of the present application is fixed to the inner wall of the cabinet 1 through a clamping sleeve 19 and a support rod, and a handle 21 is provided to facilitate the opening and closing of the cabinet door 4.

[0023] In the third embodiment, based on the second embodiment, the mounting sleeve 10 and the locking rod 11 are vertically connected via the vertical groove 16 and the slider 17 , so as to ensure that the locking rod 11 can move vertically along the axis of the mounting sleeve 10 .
