In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] Example 1

[0042] The present invention provides an emergency tripping device, such as Figure 1-8 As shown, the emergency tripping device includes a fixed bracket and a tripping assembly, and the tripping assembly includes a shell 1, a rotating member, a push rod, a locking member 3 and an elastic member 5, and the shell 1 is fixedly connected to the fixed bracket; the push rod is slidably arranged on the shell 1 along the axial direction of the push rod, and the push rod is slidably arranged on the shell 1 and has an energy-stored position and an energy-unstored position. When the push rod is in the energy-unstored position, the push rod presses the tripping button of the switch cabinet; the rotating member is rotatably arranged on the shell 1 along the circumferential direction of the push rod, and the rotating member is rotatably arranged on the shell 1 and has a locked position and a ready position. The rotating member is configured so that the rotating member rotates from the ready position to the locked position to push the push rod to slide from the energy-unstored position to the energy-stored position to compress the elastic member 5; the locking member 3 is fixedly arranged on the shell 1, and the locking member 3 can be remotely controlled to lock or unlock the push rod in the energy-stored position; the elastic member 5 can drive the push rod to slide from the energy-stored position to the energy-unstored position.

[0043] In the emergency tripping device, the rotating member can push the push rod to slide from the non-energy storage position to the energy storage position to compress the elastic member 5 during the process of rotating from the ready position to the locked position, and the rotating member is rotated from the ready position to the locked position to store energy in the elastic member 5. The elastic member stores energy due to being compressed. When the rotating member is in the locked position, the push rod slides to the energy storage position. At this time, the locking member 3 locks the push rod in the energy storage position, and then the rotating member is rotated from the locked position to the ready position. When the tripping button needs to be pressed, the locking member 3 only needs to unlock the push rod in the energy storage position. Under the action of the elastic member 5, the push rod slides from the energy storage position to the non-energy storage position until it slides to the non-energy storage position to press the tripping button. Since the locking member 3 in the emergency tripping device can be remotely controlled to lock or unlock the push rod in the energy-storing position, the operation and maintenance personnel do not need to approach the switch cabinet to press the tripping button. When the switch cabinet is working normally, the rotating member is rotated to push the push rod to the energy-storing position and locked with the locking member 3. When the rotating member is rotated to the ready position, when the tripping button needs to be pressed, the operation and maintenance personnel can remotely control the locking member 3 to unlock the push rod, so that the push rod slides to the non-energy-storing position under the action of the elastic member 5 to press the tripping button. The emergency tripping device enables the operation and maintenance personnel to remotely perform emergency tripping of the faulty switch cabinet at a safe distance, ensuring the safety of the operation and maintenance personnel, and has a simple structure, convenient operation, and low cost.

[0044] Alternatively, if Figure 4-7 As shown, the push rod includes a rod body 41 and a guide seat 42 connected to the rod body 41, and the guide seat 42 is provided with an abutment block 43; the rotating member includes a rotating sleeve 21, the rotating sleeve 21 is rotatably arranged in the housing 1, the push rod is arranged in the rotating sleeve 21, and the rotating sleeve 21 is provided with a guide surface 211, and the guide surface 211 is configured so that the abutment block 43 abuts against the guide surface 211 so that the rotating member can push the push rod to slide from the non-energy storage position to the energy storage position. Through the abutment block 43 abutting against the guide surface 211, the rotating sleeve 21 rotates along the circumferential direction of the push member to push the push rod to slide along the axial direction of the push rod, which can make the structure more compact and save operating space, and facilitate the operation and maintenance personnel to exert force. According to the principle of leverage, compared with pushing the push rod in the axial direction of the push rod, rotating the rotating sleeve 21 along the circumferential direction of the push rod can make the operation and maintenance personnel more labor-saving.

[0045] Optionally, the rotating sleeve 21 is provided with an annular groove 212, and the inner wall of the housing 1 is provided with an annular boss, which is located in the annular groove 212. The annular boss rotates in the annular groove 212, so that the rotating sleeve 21 can only rotate relative to the housing 1 along the circumferential direction of the push rod, and cannot move along the axial direction of the push rod, thereby limiting the position of the rotating sleeve 21.

[0046] Optionally, the rotating member further includes a handle 22, and the handle 22 is fixedly connected to the rotating sleeve 21. The operation and maintenance personnel can rotate the rotating sleeve 21 by pressing the handle 22, which is convenient for the operation and maintenance personnel.

[0047] Optionally, the locking member 3 is an electromagnetic push rod 31, and the abutment block 43 can abut against the side of the push rod 31 of the electromagnetic push rod away from the opening button. The push rod 31 of the electromagnetic push rod can be extended or retracted. When the push rod 31 of the electromagnetic push rod is extended, it abuts against the abutment block 43 of the push rod located at the energy-storing position, and the abutment block 43 is relatively far away from the opening button of the push rod 31. At this time, the electromagnetic push rod locks the push rod in the energy-storing position. When the push rod 31 of the electromagnetic push rod is retracted, the electromagnetic push rod unlocks the position of the push rod, and the push rod can slide in the non-energy-storing direction. The extension or retraction of the push rod 31 of the electromagnetic push rod can be controlled by remote control. Optionally, the electromagnetic push rod includes a coil and a push rod 31. In this embodiment, the push rod 31 retracts when the coil is energized; the push rod 31 extends when the coil is de-energized. In other embodiments, the push rod 31 extends when the coil is energized; the push rod 31 retracts when the coil is de-energized.

[0048] Optionally, the rod body 41 is provided with a baffle 412 , the elastic member 5 is a spring, the spring is sleeved on the rod body 41 , and two ends of the spring respectively abut against the baffle 412 and the rotating sleeve 21 .

[0049] Optionally, the rod body 41 is provided with a screw connection portion 411, and the guide seat 42 is screwed to the screw connection portion 411; along the axial direction of the push rod, the length of the screw connection portion 411 is greater than the length of the guide seat 42. Since along the axial direction of the push rod, the length of the screw connection portion 411 is greater than the length of the guide seat 42, the position of the guide seat 42 screwed to the screw connection portion 411 can be adjusted to adjust the compression amount of the elastic member 5 when the push rod is in the energy-storing position, so as to adapt to the situation where the force required to press the opening button of different switch cabinets is different. For different types of switch cabinets, the force of pressing the opening button is adjusted by adjusting the position of the guide seat 42 on the screw connection portion 411 to ensure that the emergency opening device can reliably and smoothly open the switch.

[0050] Alternatively, if Figure 1-3 As shown, the housing 1 is provided with a first elongated hole 11 extending along the axial direction of the push rod, and the first bolt 6 passes through the first elongated hole 11 and is screwed with the locking member 3. Loosen the first bolt 6, and the locking member 3 can slide along the first elongated hole 11. When the locking member 3 slides to a suitable position, tighten the first bolt 6 to fix the position of the locking member 3. The position of the locking member 3 along the axial direction of the push rod can be adjusted. By adjusting the position of the locking member 3, the stroke between the energy-storing position and the non-energy-storing position of the push rod can be adjusted to adapt to the situation that the stroke required for pressing the opening button of different switch cabinets is different. This ensures reliable and smooth opening of different types of switch cabinets.

[0051] Optionally, the housing 1 is provided with a second elongated hole 12 extending along the axial direction of the push rod, and the second bolt 8 passes through the second elongated hole 12 and is screwed to the fixing bracket. The distance between the fixing bracket and the switch cabinet can be adjusted to adapt to different environmental conditions around the switch cabinet.

[0052] Optionally, the fixing bracket includes a first bracket 72 and a second bracket 71, the second bracket 71 is connected to the housing 1, the second bracket 71 is penetrated in the first bracket 72, the second bracket 71 is provided with a third long hole extending in the vertical direction, the first bracket 72 is provided with a connecting hole, the third bolt 9 penetrates the third long hole and the connecting hole, and is screwed with a nut. The height of the fixing bracket can be adjusted to adapt to switch cabinets with different heights of the opening buttons.

[0053] Optionally, the housing 1 is provided with a first logo 13 at a position corresponding to the locked position of the rotating part, and the housing 1 is provided with a second logo 14 at a position corresponding to the ready position of the rotating part. In this embodiment, the first logo 13 is "locked" and the second logo 14 is "ready". Optionally, a third logo 421 is provided on the guide seat 42. The third logo 421 is "energy stored". When the push rod is in the energy stored position, the third logo 421 on the guide seat 42 will be exposed. It is convenient for operation and maintenance personnel to intuitively understand the status of the emergency trip device.

[0054] Example 2

[0055] The difference between this embodiment and the first embodiment is that the locking member 3 is different, and the other parts are the same.

[0056] In this embodiment, the locking member 3 is an electric push rod. The electric push rod includes a motor and a push rod. The motor and the push rod are in transmission connection, and the motor can drive the push rod to extend or retract to lock or unlock the position of the push rod. The electric push rod 31 can be controlled by remote control.

[0057] Among them, the specific structure of the electric push rod belongs to the existing technology and will not be repeated here.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
