Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, and specifically to an operating switch protection structure. Background Technology

[0002] Switchgear is a crucial piece of equipment in power systems used for the distribution, control, and protection of electrical energy. It integrates various switching devices, measuring instruments, protection devices, and auxiliary equipment. Typically installed in power plants, substations, industrial facilities, and commercial buildings, it ensures the safe, reliable, and efficient operation of the power system. The switchgear door houses multiple sets of operating switches for controlling the internal structure, such as circuit breaker operating switches, disconnecting switches, and safety control switches. For ease of operation, these switches often lack external covers. This means that when the switchgear is installed in a humid environment, external moisture easily adheres to the switches and enters the interior through gaps. The confined internal environment hinders airflow, making it difficult for moisture to dissipate. Over time, this can lead to aging and damage to internal components, compromising stable operation.

[0003] In view of this, a design or technical improvement is proposed to solve the above problems.

[0004] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figure 1-13 The illustrated operating switch protection structure includes a switch cabinet body 1, a cabinet door 11, and an operating switch 12 mounted on the cabinet door 11. A fixed cover 2, fixed to the cabinet door 11, is provided outside the operating switch 12. A sliding door 21, which can slide up and down, is provided on the fixed cover 2. A locking pin assembly is provided between the sliding door 21 and the fixed cover 2 for locking. When the sliding door 21 is pushed downwards, the locking pin assembly automatically opens, allowing the sliding door 21 to slide freely. When the sliding door 21 slides upwards to the top position, the locking pin assembly automatically locks, fixing the sliding door 21 relative to the fixed cover 2. By providing the fixed cover 2 and the sliding door 21 on the outside of the operating switch 12, the operating switch 12 is isolated from the outside environment. Therefore, when the operating environment is humid, the sliding door 21 can effectively prevent moisture from entering the interior of the operating switch 12 and causing component aging. At the same time, the convenient opening method of the sliding door 21 does not reduce the immediate operating efficiency of the operator.

[0034] In one embodiment, the fixed cover 2 has limiting grooves 22 on both sides, and the sliding door 21 has limiting sliders 23 on both sides that limit the sliding within the limiting grooves 22. The upper end of the sliding door 21 has a first receiving cavity 3, and the fixed cover 2 has a slot 31. The pin lock assembly includes a locking plate 32 that moves back and forth relative to the slot 31 within the first receiving cavity 3, a pin 33 that is disposed on the locking plate 32 and moves through the sliding door 21 and is adapted to be inserted into the slot 31, and a pin rod 33 that is disposed below the locking plate 32 and is connected to the locking plate 32. A control plate 35 with a first wedge-shaped surface 34 that is mutually adapted to each other and a pull rod 37 that is limited to sliding within a limiting sliding hole 36 opened on the side wall of the first receiving cavity 3 on the control plate 35 are provided. A first return spring 4 is provided at the end of the locking plate 32 away from the pin 33. The end of the first return spring 4 away from the locking plate 32 is connected to the inner wall of the first receiving cavity 3. A second receiving cavity 5 is opened on the side wall of the first receiving cavity 3 opposite to the locking plate 32. A limiting plate 51 is provided inside the second receiving cavity 5. The limiting plate 51 and the... A second return spring 52 is provided between the inner walls of the second receiving cavity 5. A side plate 53 corresponding to the limiting plate 51 is provided on the side wall of the locking plate 32. At the same time, the side of the limiting plate 51 opposite to the side plate 53 is set as an arc surface. A third receiving cavity 6 is also provided on the side of the second receiving cavity 5 away from the first receiving cavity 3, which is isolated from it. A connecting rod 61 is provided on the limiting plate 51, which is provided through the second receiving cavity 5 and the third receiving cavity 6. A rear abutment is provided on the part of the connecting rod 61 located in the third receiving cavity 6. 62; A limiting cavity 63 communicating with the side end of the third accommodating cavity 6 is provided. A trigger rod 64 that slides relative to the side of the fixed cover 2 is provided in the limiting cavity 63. A second wedge-shaped surface 65 that cooperates with the trigger rod 64 and the rear abutment block 62 is provided. A relief groove 7 is provided on the side of the limiting cavity 63 away from the third accommodating cavity 6 and communicating with it. The end of the trigger rod 64 extends from the limiting cavity 63 into the relief groove 7. A wedge plate 71 that is adapted to the end of the trigger rod 64 is provided on the fixed cover 2.

[0035] With the sliding door 21 completely covering the fixed cover 2, the pin 33 is inserted into the first receiving cavity 3, locking the sliding door 21 onto the fixed cover 2. When it is necessary to open the sliding door 21, the operator can manually pull down the pull rod 37, causing the control plate 35 inside the first receiving cavity 3 to move down synchronously. Then, the control plate 35 is pushed backward by the first wedge surface 34, and the pin 33 is pulled out from the first receiving cavity 3. During the process of the pin 33 being pulled out, the side plate 53 at the side end of the locking plate 32 will abut against the limiting plate 51, thereby pushing the limiting plate 51 towards the first receiving cavity 32. The movement within the second accommodating cavity 5 contracts until the locking plate 32 moves to the point where it disengages from the side plate 53 and the limiting plate 51. At this point, the limiting plate 51 rebounds under the action of the second return spring 52, and its back abuts against the side plate 53 to lock the locking plate 32, preventing it from rebounding. This ensures that the rebound force of the first return spring 4 will not push the locking plate 32 to reset, thus preventing the pin 33 from getting stuck on the inner wall of the fixed cover 2 and interfering with the movement of the sliding door 21 when it moves upward. At this point, if the pull rod 37 is pulled down further, the pin 33 will drive the sliding door 21 downward synchronously, thereby opening it. Inside the fixed cover 2, when the sliding door 21 needs to be closed, the pull rod 37 is pushed upwards, which in turn moves the control plate 35 upwards, causing the first wedge-shaped surface 34 between the control plate 35 and the locking plate 32 to disengage. The control plate 35 then abuts against the upper part of the locking plate 32, causing it to move synchronously. The locking plate 32, through the pin 33, moves the sliding door 21 upwards as a whole. When the pin 33 aligns with the first receiving cavity 3, the trigger rod 64 at the side end of the pin 33 is retracted by the wedge plate 71, causing the rear end of the trigger rod 64 to abut against the wall. Block 62 pushes the limiting plate 51 to retract, thereby disengaging the limiting plate 51 from the side plate 53 again. This causes the locking plate 32 to rebound under the action of the first return spring 4, and then the pin 33 is locked into the first receiving cavity 3. Through the coordinated action of the above structure, the operator only needs to pull the lever 37 up and down to realize the up and down movement, opening and closing of the sliding door 21. While protecting the internal operating switch 12, it does not produce troublesome opening and closing actions, and does not occupy too much external space, providing an efficient and convenient protection function.

[0036] In one embodiment, the bottom of the fixed cover 2 is provided with a V-shaped groove 8, and a water receiving groove 81 connected to the lower surface of the fixed cover 2 is provided below the V-shaped groove 8. The V-shaped groove 8 is provided so that when moisture enters the fixed cover 2, it can be discharged into the water receiving groove 81. At the same time, in order to accelerate the downward flow of moisture, a sponge block 82 is placed inside the water receiving groove 81 to absorb moisture. Meanwhile, a baffle 83 is provided at the front end. The baffle 83 is fixed to the water receiving groove 81 by screws 84, and the sponge block 82 is replaced regularly.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
