[0003] The traditional isolating switch mechanism is not so stable in terms of remote tripping. After the tripping is completed, the current position is generally located by an electromagnet. However, when the electromagnet is accidentally powered off, the current position cannot be locked. At this time, the isolating switch may be closed, which may cause a safety accident. In addition, the existing isolating switch has a long closing time when performing a closing operation, and an arc may be generated during the closing process.

[0015] As a preferred embodiment of the present invention, a first auxiliary block is installed on the sliding seat, a second auxiliary block is installed on the bottom of the flat plate, the first auxiliary block and the second auxiliary block are adapted to each other, a slider is installed on the base, the slider and the limit rod installed on the bottom cover are plugged into each other, and a spring is installed between the slider and the bottom cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When the present invention is performing the gate opening operation, the operator can manually rotate the rotating rod, and the rotating rod can drive the turntable to rotate, and the connecting sleeve at the bottom of the turntable rotates synchronously, and at this time the first torsion spring and the second torsion spring on the connecting sleeve are twisted synchronously to perform a force storage operation. When the turntable drives the card plate to rotate, the card plate can contact the extrusion inclined surface on the seesaw. At this time, the entire seesaw is squeezed and slides downward. The magnet at the bottom of the seesaw can be adsorbed on the electromagnet body at this time, and the push rod on the first torsion spring can eventually push the extrusion block to move. Until the push rod moves to the back of the extrusion block at this time, the push rod at this time is limited and fixed by the force storage spring, thereby increasing its stability, ensuring that no accidental gate closing will occur in the later stage, and increasing safety. In the above process, the protrusion and the lifting block are squeezed, and at this time the lifting block is squeezed and moves downward, driving the base and the circuit control contact to move downward, ultimately achieving the purpose of remote tripping, and the reliability of use is stronger.

[0017] When the present invention is closing the gate, the operator can replace the positive and negative poles of the circuit passed through the electromagnet body. At this time, the electromagnet will repel the magnet in the fixed position. At this time, the magnet and the seesaw rotate synchronously in opposite directions. After the seesaw is lifted, the seesaw squeezes the baffle plate to move up. At this time, the baffle plate will drive the squeezing block to move up. At this time, the top rod limit on the first torsion spring is released. At this time, the first torsion spring and the second torsion spring drive the rotating rod to reset as a whole. The first torsion spring and the second torsion spring are in a force storage state during the gate opening process. Therefore, when closing the gate, the force-storing torsion spring can accelerate the rotation of the rotating rod to quickly close the gate, further reducing the time for arc generation and the operation. More specifically, when the card plate moves to the back of the seesaw, the position of the seesaw is repelled by the magnet, so the position of the seesaw is fixed, and the card plate will rotate, and the tension spring can be pulled during the rotation of the card plate, and finally the card plate will be separated from the seesaw, and the tension spring can synchronously drive the card plate to reset. The card plate and the seesaw are set in such a way that they can only be locked in one direction, reducing the possibility of incorrect use, and the rotating rod is always rotating, and finally the rotating rod can reset the base, thereby achieving the effect of closing the gate. In the above process, the closing operation can be completed only by controlling the electromagnet, and then it can be controlled at a long distance, and the operation is more convenient.

[0018] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

A protrusion 612 is installed at the bottom of the flat plate 51, and the protrusion 612 rotates to squeeze the lifting block 611, thereby driving the base 6 with the lifting block 611 installed to move vertically. At this time, the circuit control contact at the bottom can move synchronously, thereby achieving the purpose of closing the gate.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, in a specific embodiment, four positioning posts 121 are installed on the bearing plate 12, and the tops of the four positioning posts 121 are adapted to the positioning holes opened at the bottom of the upper cover 11, and locking bolts 122 are screwed between the upper cover 11 and the positioning posts 121. The installation between the bearing plate 12 and the upper cover 11 is completed by the locking bolts 122, and a mounting seat 111 is welded on the top of the upper cover 11. A connecting rod 21 is installed movably through the inside of the mounting seat 111, and the bottom of the connecting rod 21 is connected to the rotating rod 2.

[0027] Embodiment 2:

[0028] The difference between the above embodiment and this embodiment is that: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig.13 As shown, an electromagnet contact 321 is installed at the output end of the electromagnet body 322, and the electromagnet contact 321 is adapted to each other.

A reset slope 311 is provided on the seesaw 3, and a rotating shaft 331 is installed at the rotation center of the seesaw 3. A positioning seat 33 is installed at the end of the rotating shaft 331, and the positioning seat 33 is welded on the supporting plate 12, wherein the rotating shaft 331 limits the rotation center of the seesaw 3.

[0029] like Figure 5 and Figure 6As shown, in a specific embodiment, an auxiliary rod 411 is installed on the extrusion block 41, and an auxiliary sleeve 412 is installed on the auxiliary rod 411. The auxiliary sleeve 412 is installed at the bottom of the upper cover 11. The auxiliary rod 411 is movable through the inner cavity of the locking cover 4, and the force storage spring 413 is clamped at the end of the auxiliary rod 411 and the inner cavity of the auxiliary sleeve 412, and the force storage spring 413 is always in a compressed state. The end of the push rod 521 slides to the bottom of the extrusion block 41. With the extrusion of the two, the extrusion block 41 will move upward at this time, so that the push rod 521 moves to the back of the extrusion block 41. However, when the extrusion block 41 moves upward, the extrusion block 41 drives the auxiliary rod 411 to slide inside the auxiliary sleeve 412, which plays a guiding role, and the force storage spring 413 inside the auxiliary sleeve 412 is compressed synchronously, so after the push rod 521 moves to the back of the extrusion block 41, the force storage spring 413 will push the extrusion block 41 to reset, and then the entire push rod 521 is limited.

[0030] like Figure 3 , Figure 5 and Figure 8 As shown, further, a through slot 421 is provided on the side wall of the locking cover 4, and the through slot 421 is communicated with the extrusion block 41, and the baffle 42 is slidably arranged in the through slot 421, and a pressing block 422 is installed on the baffle 42 located outside the through slot 421, and an anti-slip groove is provided at the bottom of the pressing block 422, and the pressing block 422 and the surface of the rocker 3 are located on the same vertical plane, and the pressing block 422 is attached to the rocker 3. When the rocker 3 rotates upward, the rocker 3 can squeeze the pressing block 422 on the surface, and at this time, the pressing block 422 slides upward along the through slot 421, and the baffle 42 on the pressing block 422 drives the extrusion block 41 to move upward synchronously.

[0031] Embodiment 3:

[0032] The difference between the above embodiment and this embodiment is that: Figure 8 , Fig. 9 , Fig.10 and Fig.12 As shown, a through hole is provided at the center of the carrier plate 12, and the flat plate 51 rotates on the through hole. An annular guide rail 123 is provided on the outside of the through hole, and a notch 124 is provided at one end of the annular guide rail 123. A clamping rod 522 is clamped inside the notch 124. The clamping rod 522 is connected to the end of the first torsion spring 52 away from the top rod 521. A side plate 511 is installed on the flat plate 51, and a protrusion 512 is installed on the side plate 511. A moving rod 531 is installed at one end of the second torsion spring 53, and the moving rod 531 is clamped to the protrusion 512 at the bottom. A fixing rod 532 is installed at the other end of the second torsion spring 53, and a positioning block 62 is connected to the end of the fixing rod 532. The end of the positioning block 62 is connected to the base 6. The above structure can locate the installation positions of the first torsion spring 52 and the second torsion spring 53.

[0033] like Fig.10 As shown, further, a first auxiliary block 613 is installed on the slide 61, and a second auxiliary block 614 is installed at the bottom of the flat plate 51. The first auxiliary block 613 and the second auxiliary block 614 are adapted to each other. A slider 63 is installed on the base 6. The slider 63 and the limit rod installed on the bottom cover 14 are plugged into each other, and a spring is installed between the slider 63 and the bottom cover 14. The limit rod and the spring are prior art, so they are not drawn in the figure. The main purpose of the spring is to ensure that the first auxiliary block 613 and the second auxiliary block 614 can fit. When the flat plate 51 rotates, the positions of the protrusion 612 and the second auxiliary block 614 at the bottom of the flat plate 51 change synchronously. The final protrusion 612 and the second auxiliary block 614 will squeeze each other with the lifting block 611 and the first auxiliary block 613, thereby driving the slide 61 installed with the lifting block 611 and the first auxiliary block 613 to move downward, and the slide 61 drives the base 6 to move downward synchronously, and the circuit control contact at the bottom of the base 6 moves downward synchronously, and finally the purpose of opening the gate can be achieved.

[0034] The implementation principle of a disconnector with remote tripping in this embodiment is as follows: When the gate opening operation is required, the operator can first turn the knob 211, and the knob 211 can drive the connecting rod 21 to rotate on the mounting seat 111 and the upper cover 11, and the connecting rod 21 can drive the rotating rod 2 to rotate, and the rotating rod 2 can rotate clockwise to close the gate. Figure 3 As a benchmark.

[0035] When the rotating rod 2 rotates clockwise, the connecting sleeve 5 on the rotating rod 2 rotates synchronously, and the connecting sleeve 5 drives the flat plate 51 to rotate. At this time, the relative positions between the flat plate 51 and the supporting plate 12 change, and then the protrusions 512 on the upper and lower sides can drive the first torsion spring 52 and the second torsion spring 53 to twist, and the first torsion spring 52 and the second torsion spring 53 are used to facilitate the subsequent resetting operation.

[0036] When the plate 51 rotates, the positions of the protrusion 612 and the second auxiliary block 614 at the bottom of the plate 51 change synchronously, and finally the protrusion 612 and the second auxiliary block 614 will squeeze each other with the lifting block 611 and the first auxiliary block 613, thereby driving the slide 61 on which the lifting block 611 and the first auxiliary block 613 are installed to move downward, and the slide 61 drives the base 6 to move downward synchronously, and the circuit control contacts at the bottom of the base 6 move downward synchronously, and finally the purpose of opening the gate can be achieved.

[0037] And during the clockwise rotation of the rotating rod 2, the rotating rod 2 drives the rotating disk 22 at the bottom to rotate clockwise, and the rotating disk 22 drives the connecting seat 221 and the synchronous bracket 223 on the surface to start rotating, wherein the card plate 224 on the synchronous bracket 223 can move toward the seesaw 3, and the card plate 224 fits with the extrusion slope 31 on the seesaw 3, and finally the entire seesaw 3 rotates along the rotating axis 331, so that the card plate 224 can move above the seesaw 3.

[0038] After the seesaw 3 rotates, the magnet 32 ​​at the bottom of the seesaw 3 can be adsorbed on the energized electromagnet body 322 to ensure that the position of the seesaw 3 does not move.

[0039] And when the first torsion spring 52 is twisted, the push rod 521 on the first torsion spring 52 also rotates clockwise, and the end of the push rod 521 can eventually slide to the bottom of the extrusion block 41. With the extrusion of the two, the extrusion block 41 will move upward, causing the push rod 521 to move to the back of the extrusion block 41. However, when the extrusion block 41 moves upward, the extrusion block 41 drives the auxiliary rod 411 to slide inside the auxiliary sleeve 412, playing a guiding role, and the force storage spring 413 inside the auxiliary sleeve 412 is compressed synchronously, so after the push rod 521 moves to the back of the extrusion block 41, the force storage spring 413 will push the extrusion block 41 to reset, and then the entire push rod 521 is limited, and the first torsion spring 52 is locked at this time, and then the rotating rod 2 will not reset at this time, and finally the current state can be positioned.

[0040] When a quick closing operation is required later, the operator can replace the positive and negative poles of the circuit connected to the electromagnet body so that the electromagnet contact 321 has the same magnetic properties as the contact surface of the magnet 32, thereby repelling the magnet 32. At this time, the magnet 32 ​​can drive the seesaw 3 to rotate in the opposite direction. When the seesaw 3 rotates upward, the seesaw 3 can squeeze the pressing block 422 on the surface. At this time, the pressing block 422 slides upward along the through groove 421, and the baffle 42 on the pressing block 422 drives the squeezing block 41 to move up synchronously, and then the top rod 521 is unlocked. At this time, the first torsion spring 52 and the second torsion spring 53 facilitate the reverse movement of the rotating rod 2, pushing the flat plate 51 to rotate to the initial state. At this time, the lifting block 611 and the protrusion 612 are separated and reset to the initial state, and finally the closing operation is completed.

[0041] During the counterclockwise rotation and reset process of the rotating rod 2, the rotating disk 22 on the rotating rod 2 starts to rotate synchronously, and the card plate 224 on the rotating disk 22 will first contact and block the reset inclined surface 311, and at this time the rocker 3 will not be squeezed and rotated downward. At this time, as the rotating disk 22 continues to move, the card plate 224 rotates around the rotation center, and the tension spring 222 is stretched. Until the card plate 224 rotates to a certain extent, the surface of the card plate 224 will fit the surface of the rocker 3, and finally the rocker 3 will separate from the card plate 224, and at this time it will be restored to the initial state through the tension spring 222.

[0042] When the turntable 22 rotates clockwise, the card plate 224 will press the seesaw downward. When it rotates counterclockwise, the card plate 224 will become a movable part and can rotate counterclockwise when encountering an obstacle. After avoiding it, the tension spring 222 will reset it, finally achieving the purpose of one-way locking.
