Description

Technical Field

[0001] This utility model relates to the field of grounding switch technology, and in particular to a grounding switch anti-misoperation mechanism. Background Technology

[0002] The 72.5kV grounding switch arose from the power system's demand for safety and reliability. As grid voltage levels rise to medium and high voltage (such as 72.5kV), the safety risks during equipment maintenance and repair also increase. Reliable grounding via a grounding switch prevents residual charge or accidental energization, ensuring the safety of personnel and equipment. Early grounding switches were primarily manually operated, with simple structures but reliant on manual operation. With technological advancements, modern grounding switches utilize high-strength materials and insulation technology, support electric operation and remote control, and are equipped with mechanical interlocking devices to ensure coordinated operation with circuit breakers. International standards (such as IEC) and industry specifications have further promoted the standardization of its design and performance, making it an indispensable safety device in high-voltage power systems and widely used in substations, transmission lines, and power plants. However, current grounding switches are usually installed outdoors, which makes it easy for unauthorized personnel to accidentally open the control box and operate it. This not only affects the normal use of electricity but also poses certain safety hazards. In the prior art, the cabinet door of the grounding switch operating mechanism is locked by a mechanical lock. However, mechanical locks may fail to lock or open over time, or they may not be locked at all. To solve the above problems, this application proposes a grounding switch anti-misoperation mechanism.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-3 As shown, a grounding switch anti-misoperation mechanism includes a support rod 1, an insulator 2 fixedly connected to the top of the support rod 1, an operating box 3 fixedly connected to the outer wall of the support rod 1, a door 4 hinged to one side of the operating box 3, and an alarm system including an alarm 5 installed on the top of the operating box 3. A contact switch button 6 connected to the alarm 5 is provided on the inner wall of the operating box 3, and a triggering component is provided on the side of the switch button 6 on the inner wall of the operating box 3. The door 4 can cooperate with the triggering component and triggers the alarm via the switch button 6. In this embodiment, the door 4 and the operating box 3 are hinged together, and a conventional mechanism can be used. The alarm system is fixed and locked by a mechanical locking structure. The alarm system specifically includes an alarm 5, which is a prior art device. It can be a combination of sound alarm and light alarm. In this application, the alarm 5 is activated and deactivated by a contact switch button 6. When in use, the door 4 is closed and fixed by a limit component, which can effectively prevent the door 4 from being opened accidentally. The alarm 5 is fixedly connected to the top of the control box 3. A wireless signal transmission module is fixedly installed inside the alarm 5. When the alarm 5 is powered on, it can quickly send an electrical signal to the receiving end through the wireless signal transmission module. When the personnel at the receiving end are aware that the door 4 of the control box 3 has been opened accidentally, they can quickly go to check.

[0019] Preferably, the side of the control box 3 is provided with a limiting component for fixing the box door 4. The limiting component includes a fixing block 7 disposed on the side of the control box 3. A connecting rod 8 is rotatably connected to one side of the fixing block 7. A limiting block 9 is fixedly connected to one end of the connecting rod 8 away from the fixing block 7. An L-shaped locking block 10 matching the limiting block 9 is fixedly connected to the box door 4. In this embodiment, when the box door 4 is closed, the connecting rod 8 is rotated to drive the limiting block 9 to lock into the L-shaped locking block 10, which can effectively fix the box door 4. When it is necessary to open the box door 4, the limiting block 9 is rotated in the opposite direction to disengage it from the L-shaped locking block 10, and then the box door 4 can be rotated to open it, thereby facilitating the maintenance of the inside of the control box 3 by the staff.

[0020] Preferably, the triggering component includes a fixed housing 11 disposed on the inner wall of the operation box 3 on one side of the switch button 6. A movable block 12 is slidably connected inside the fixed housing 11. One end of the movable block 12 extends out of the fixed housing 11, and a spring 13 is fixedly connected to the other end. The end of the spring 13 away from the movable block 12 is connected to the inner wall of the fixed housing 11. In this embodiment, as shown... Figure 3-5 As shown, a fixed housing 11 is installed on the side of the switch button 6. A movable block 12 is slidably connected inside the fixed housing 11. One end of the movable block 12 is elastically connected to the inner wall of the fixed housing 11 through a spring 13. When in use, when the spring 13 is in a relaxed state, one end of the movable block 12 extends outward to the outside of the box 3. At this time, the movable block 12 will contact the switch button 6 and trigger an alarm.

[0021] Preferably, the side of the movable block 12 extending from one end of the fixed shell 11 is set as an inclined surface. The inclined surface of the movable block 12 contacts the switch button 6 when the spring 13 is relaxed. In this embodiment, when an unauthorized person accidentally opens the door 4 on the control box 3, the movable block 12 will pop out under the action of the spring 13. The inclined surface at the top of the movable block 12 will press the switch button 6, thereby causing the alarm 5 to sound an alarm, thus alerting unauthorized personnel. When the door 4 is closed, the door 4 will press the movable block 12 to slide into the fixed shell 11. When the movable block 12 is disengaged from the switch button 6, the alarm 5 will stop sounding an alarm. Then, the door 4 will be fixed by the limiting component, and the device can operate normally. In this embodiment, the inclined surface of the movable block 12 can better press the switch button 6 when it contacts it.

[0022] Preferably, the movable block 12 is fixedly connected to a symmetrical slider 14 on its side inside the fixed housing 11, and the inner wall of the fixed housing 11 is provided with a groove 15 that matches the slider 14. For example, in this embodiment...

When in use, the movable block 12 can slide in the groove 15.

[0023] Preferably, a wireless signal transmission module is fixedly installed inside the alarm 5. When the alarm 5 is powered on, it can send an electrical signal to the receiving end through the wireless signal transmission module. The alarm 5 is fixedly connected to the top of the control box 3. The wireless signal transmission module is fixedly installed inside the alarm 5. When the alarm 5 is powered on, it can quickly send an electrical signal to the receiving end through the wireless signal transmission module. After the staff at the receiving end learns that the door 4 of the control box 3 has been accidentally opened, they can quickly go to check.

[0024] Preferably, a camera 16 is fixedly installed on the top of the control box 3 on one side of the alarm 5. The camera 16 is connected in series and electrically with the alarm 5. When the alarm 5 is activated, the camera 16 will simultaneously capture images of the surrounding environment, which can effectively prevent criminals from stealing the electronic components inside the control box 3.

[0025] Preferably, a battery is fixedly installed inside the alarm 5, which is used to power the alarm 5 and the camera 16.

[0026] Preferably, the movable block 12 extends from one end of the fixed shell 11 and is rotatably connected to two sets of balls 17, which are symmetrically arranged on the movable block 12.

[0027] Preferably, the surface of the box door 4 is provided with a handle, which is used to facilitate the staff to open the box door 4.

[0028] The specific working method of this application is as follows: When the grounding switch is in use, if an unauthorized person accidentally opens the door 4 on the control box 3, the moving block 12 will pop out under the action of the spring 13. The inclined surface at the top of the moving block 12 will press the switch button 6, thereby causing the alarm 5 to sound an alarm, thus alerting unauthorized personnel. When the alarm 5 is powered on, it can quickly send an electrical signal to the receiving end through the wireless signal transmission module. After the staff at the receiving end learns that the door 4 of the control box 3 has been accidentally opened, they can quickly go to check. The camera 16 will simultaneously capture the surrounding environment, which can effectively prevent criminals from stealing the electronic components inside the control box 3. After closing the door 4, rotating the limit block 9 so that it is locked inside the L-shaped locking block 10 can provide a good fixing effect on the door 4, and the device can then operate normally. When the staff needs to perform maintenance on the inside of the control box 3, they can rotate the limit block 9 in the opposite direction to disengage it from the L-shaped locking block 10, and then rotate the door 4 to open it. Since the alarm 5 is connected to a wireless controller, the wireless controller can control the alarm 5 to stop sounding, thus facilitating the staff to inspect the inside of the control box 3.
