Description

Technical Field

[0001] This utility model belongs to the field of substation technology, specifically relating to a locking device for a substation. Background Technology

[0002] Substations play a vital role in the power system, controlling and protecting its operation to ensure its safe and stable operation. Equipped with various switching devices, relay protection devices, and automation systems, substations can monitor and control parameters such as current, voltage, and power. When a fault or abnormality occurs, they can promptly disconnect the faulty circuit to protect equipment and personnel.

[0003] In substations, the locking device of the box-type substation door is a crucial component for ensuring the safety of internal equipment. Existing technology, such as the locking device for a box-type substation with patent publication number CN221546691U, includes a base, a box body, a positioning rod, and a positioning mechanism. The positioning mechanism includes a locking box, a moving plate, two springs, a U-shaped frame, and an unlocking rod. However, this device has significant drawbacks. Frequent insertion and disengagement of the positioning rod with the positioning hole on the moving plate generates friction. Long-term use may cause wear on the edges of the positioning rod and the positioning hole, leading to decreased fitting accuracy and affecting the stability of the lock. When the positioning rod is inserted into the positioning hole, if it is subjected to external impact or the box door shakes, the friction and collision between the positioning rod and the positioning hole will increase, accelerating wear and reducing the reliability of the box door lock, thus increasing substation equipment maintenance costs and safety hazards.

[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. Example

[0022] Please see Figures 1-4 This is the first embodiment of the present invention, which provides a locking device for a substation, including...

[0023] The base 1 has a box 2 mounted on top of it. The base 1 provides support for the box 2. The front surface of the box 2 is hinged with a door 21, which can be opened to maintain the interior of the box 2.

[0024] The locking assembly includes a plate 3 mounted on the front surface of the door 21, which can be fixed with screws or bolts to increase the stability of the plate 3. A threaded groove 31 is formed in the center of the front surface of the plate 3. A stabilizing seat 4 is mounted on the top of the base 1 and located on one side of the housing 2. A slot 41 is formed on the front surface of the stabilizing seat 4 for the threaded groove 31 to be inserted. When the door 21 is opened and rotated 180 degrees, the plate 3 is inserted into the slot 41. The locking assembly also includes a slot 41 formed on the rear surface of the stabilizing seat 4. The threaded hole 42 is connected to the threaded hole 42, and the threaded rod 6 is threadedly connected to the threaded hole 42. One end of the threaded rod 6 can be threadedly connected to the threaded groove 31. Rotating the threaded rod 6 and tightening it in the threaded groove 31 fixes the insert plate 3 in the slot 41, thus stabilizing the opened box door 21. Compared with the existing technology of the positioning rod and positioning hole, this effectively avoids the friction and wear problem caused by frequent insertion and removal, improves the locking stability of the box door 21, and ensures the safety of substation equipment maintenance and other operations.

[0025] In this embodiment, preferably, a knob 8 is also installed at the other end of the threaded rod 6, and the knob 8 is located behind the stabilizing base 4, thereby increasing the convenience of rotating the threaded rod 6.

[0026] In this embodiment, preferably, it also includes a fastener 7 that is fixed to the side surface of the stabilizing base 4 by screws, so that the fastener 7 is installed securely, and the fastener 7 is fixed to the bottom of the base 1 by bolts. The fastener 7 has an "L" shaped structure, and the height of the fastener 7 is one-third of the height of the stabilizing base 4. The secure fastener 7 increases the installation performance of the stabilizing base 4.

[0027] In this embodiment, preferably, a handle 210 is installed on the front surface of the door 21, and the handle 210 has a "U" shaped structure. The "U" shaped handle 210 increases the stability of the door 21 installation.

[0028] In this embodiment, preferably, an indicator light 22 is installed on the front surface of the enclosure 2. The power to the enclosure substation is turned off, and the power to the enclosure substation is determined by observing the indicator light 22. A top plate is installed on the top of the enclosure 2 to protect the top of the enclosure 2. Example

[0029] Please see Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0030] It also includes upright plates 5 symmetrically installed on the inner side of the slot 41 by screws, so that the upright plates 5 are installed firmly. The baffles 51 set on the side surface of the upright plates 5 and can be pressed against the insert plate 3. The upright plates 5 increase the support for the baffles 51. The insert plate 3 is inserted into the slot 41 and pressed against the two symmetrical baffles 51 brackets, which provides reinforcement.

[0031] It should be noted that the specific structure and working principle of the indicator light 22 in this application have been disclosed in a box-type substation locking device with patent publication number CN221546691U.

[0032] The working principle and usage process of this utility model: Before use, observe the indicator light 22 on the box 2 to confirm that the box-type substation has been de-energized and ensure safe operation; at the same time, check whether the installation of components such as the base 1, the stabilizing seat 4, and the fastener 7 is secure, and check whether components such as the insert plate 3, the threaded rod 6, and the knob 8 are damaged, and ensure that all components of the locking device are in good condition.

[0033] Hold the "U"-shaped handle 210 on the front surface of the door 21, pull it outward and rotate the door 21 so that it rotates around the hinge and opens until the door 21 rotates 180 degrees. At this time, the insert plate 3 on the door 21 is aligned with the slot 41 on the front surface of the stabilizing base 4.

[0034] Insert the insert plate 3 smoothly into the slot 41, so that the insert plate 3 is pressed against the baffles 51 symmetrically arranged on the upright plate 5 on the inner side of the slot 41, and use the upright plate 5 and the baffles 51 to initially reinforce the insert plate 3.

[0035] Hold the knob 8 located behind the stabilizer 4 and turn the knob 8 clockwise to drive the threaded rod 6 to screw down into the threaded hole 42 on the rear surface of the stabilizer 4 until one end of the threaded rod 6 is screwed into the threaded groove 31 in the center of the front surface of the insert plate 3. Tighten the threaded rod 6 to firmly fix the insert plate 3 in the slot 41, thereby achieving a stable lock on the open box door 21 and facilitating maintenance operations inside the box 2.

[0036] After the maintenance operation is completed, turn the knob 8 counterclockwise to unscrew the threaded rod 6 out of the threaded groove 31 of the insert plate 3, then hold the handle 210 and push the door 21 to rotate around the hinge and close it, so that the door 21 fits against the front surface of the box body 2.

[0037] After closing the door 21, check again whether all parts are in place, whether the fasteners 7, the insert plate 3 and other parts are securely connected, and ensure that the locking device is in normal condition, so as to prepare for the next use.

[0038] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
