Description

Technical Field

[0001] The invention relates to the technical field of electric isolation, in particular to a mechanism device of an electric isolation segmentation device. Background Art

[0002] In the prior art, an isolation segmentation device is provided at the switch position of the power equipment, and the switching of the circuit connection and the grounding is realized by opening and closing the switch, so as to facilitate the subsequent maintenance work.

[0003] The existing patent CN118116767A discloses a locking mechanism of an electric isolation segmentation device, including: a limit assembly, the limit assembly is connected to the first rotating shaft; a positioning assembly, the positioning assembly is installed on a mounting frame; a limit wheel, the limit wheel is connected to the second rotating shaft; a positioning wheel, the positioning wheel is installed on the first rotating shaft; the limit assembly is located on one side of the limit wheel, and the limit assembly is used to limit the position of the limit wheel. The locking mechanism of the electric isolation segmentation device inserts the lock link on the limit assembly into the limit hole on the limit wheel, so that the second rotating shaft cannot rotate and the grounding switch cannot be closed. The grounding switch can be limited. The guide rod on the positioning assembly is fixed above the positioning baffle, so that the positioning wheel cannot rotate clockwise and the isolation switch cannot be closed. The isolation switch can be limited to avoid accidental closure of the isolation switch, thereby ensuring the safety of electrical workers.

[0004] In the prior art, circuit opening and closing and grounding are mostly completed by two independent operations, which require the knife to be opened and then grounded. This is very likely to cause errors in subsequent operations, especially when using electric equipment for automatic drive. Once the subsequent operation is not completed or the opening and closing is forgotten, the circuit is in an ungrounded state, which is prone to safety accidents. The common knife rotation switching is very likely to cause loose connections, thereby affecting the connectivity of the circuit.

[0032] By arranging the cooperation between the electric rotating shaft 8 and the insulating support arm 10, the purpose of electrically driving the knife switch 7 for rotation and switching is achieved. By arranging the knife switch 7 between the output terminal 13 and the grounding terminal 12, the opening and closing switching of the circuit and the grounding operation can be realized by rotating the knife switch 7. The two processes are combined, thereby greatly avoiding operational errors and improving the safety of switching.

[0033] Embodiment 2: On the basis of embodiment 1, a pair of grounding side frames 3 are provided on both sides of the support frame 2, and a grounding beam 4 located directly above the electric shaft 8 is provided at the upper end of the grounding side frame 3, and a plurality of grounding terminals 12 are installed on the grounding beam 4, and the circuit connection terminal 5, the power supply terminal 6, the output terminal 13 and the input terminal 16 are all fixed to the support frame 2 through the insulator support assembly 9, and a connecting rod 15 is provided on the support frame 2. The electric shaft 8 is installed in the support frame 2 for transverse rotation, and the middle section of the electric shaft 8 rotates through the connecting rod 15. An electric drive assembly is provided on one end of the electric shaft 8, and the other end of the electric shaft 8 extends to the outside of the support frame 2, and a socket for plugging in a hand crank handle is provided at the end.

[0034] The connecting rod 15 is provided to realize the rotation installation of the electric rotating shaft 8 on the supporting frame 2, and the grounding connection of the grounding terminal 12 is realized by utilizing the grounding beam 4 and the grounding side frame 3. The electric driving assembly and the socket are respectively provided at both ends of the electric rotating shaft 8 to realize the switching between electric driving and manual driving.

[0035] The knife gate 7 is composed of a first gate plate 71 and a second gate plate 72 arranged at an interval. One end of the first gate plate 71 and the second gate plate 72 is provided with a second rotating shaft 20 rotatably connected to the input terminal 16, and the middle section of the first gate plate 71 and the second gate plate 72 is provided with a first rotating shaft 19 rotatably connected to one end of the insulating support arm 10. A rotating seat 11 is fixedly sleeved on the electric rotating shaft 8, and the other end of the insulating support arm 10 is rotatably connected to the rotating seat 11. The other ends of the first gate plate 71 and the second gate plate 72 are plugged with an adjusting component with adjustable interval width, and the adjusting component includes an insert rod 18 inserted through the ends of the first gate plate 71 and the second gate plate 72. The distance between the insert rod 18 and the end of the knife gate 7 is greater than the height of the output terminal 13, and the two ends of the insert rod 18 extend to the outside of the first gate plate 71 and the second gate plate 72 respectively, and the two end ends of the insert rod 18 are threadedly rotatably installed with adjusting nuts 14, and a first spring 24 is pressed between the adjusting nut 14 and the knife gate 7, and the first spring 24 is sleeved on the insert rod 18.

[0036] The adjusting nut 14 in the adjusting assembly is used to squeeze the first spring 24, thereby controlling the gap between the first gate plate 71 and the second gate plate 72, and realizing the adaptation of the rotational card connection between the output terminal 13 and the grounding terminal 12. The reset elastic force of the first spring 24 is used to keep the knife 7 in an elastically pressed state at the connection position with the terminal, thereby ensuring the card connection stability and avoiding the occurrence of gaps that may cause disconnection.

[0037] Example 3: On the basis of Example 2, a double-headed swivel arm 17 is fixedly sleeved on the electric shaft 8, and a fixed ring 26 fixedly sleeved on the outer wall of the electric shaft 8 is provided in the middle of the double-headed swivel arm 17. Both ends of the double-headed swivel arm 17 extend to both sides of the electric shaft 8, and the angle between the two end extension arms of the double-headed swivel arm 17 is greater than 135 degrees, and the ends of a pair of extension arms extend to the upper and lower sides of the electric shaft 8 respectively, and the extension arms are elastically pressed against the inner wall of the support frame 2.

[0038] By providing the double-headed rotating arm 17, elastic support is provided on both sides of the electric rotating shaft 8, so that the electric rotating shaft 8 is subjected to the elastic supporting force in the rotating direction.

[0039] The front and rear side walls of the support frame 2 are provided with stepped through holes 27 corresponding to the double-headed rotating arm 17, and an extrusion rod 22 is slidably inserted on the side of the stepped through hole 27 close to the double-headed rotating arm 17. A limiting seat 21 is provided on the side of the stepped through hole 27 located outside the support frame 2, and one end of the extrusion rod 22 is provided with a rotating head 28 rotatably connected to the extension arm on the double-headed rotating arm 17, the middle section of the extrusion rod 22 is sleeved with a second spring 25 and a baffle 23, a rotating rod is rotatably installed on the limiting seat 21, and the other end of the extrusion rod 22 slides through the rotating rod, the baffle 23 is pressed on the inner side of the rotating rod, and the second spring 25 is pressed between the rotating head 28 and the baffle 23.

[0040] During the rotation adjustment process of the knife switch 7, when the electric shaft 8 rotates in the forward direction and drives the knife switch 7 to rotate until it contacts the output terminal 13, the extension arm on the double-headed rotating arm 17 on the side opposite to the forward rotation direction of the electric shaft 8 moves to the upper end of the electric shaft 8 under the action of the reset elastic force of the second spring 25. Therefore, under the reset elastic force of the second spring 25, the extrusion rod 22 squeezes the extension arm, so that the electric shaft 8 has a tendency to continue to rotate in the forward direction, thereby ensuring the stability of the connection and avoiding the problem of reverse deflection or falling off.

[0041] Similarly, when the electric shaft 8 rotates in the reverse direction and the free end of the driving knife 7 contacts the ground terminal 13, the extension arm on the other side moves to the upper end of the electric shaft 8 under the reset action of the second spring 25, so that the electric shaft 8 maintains the tendency of reverse rotation.

[0042] Embodiment 4: On the basis of Embodiment 3, a telescopic inner cavity 29 is provided on the opposite side of the first gate plate 71 and the second gate plate 72, and the telescopic inner cavity 29 is located between the end of the plug rod 18 and the gate knife 7. A conductive plate 32 is elastically installed in the telescopic inner cavity 29, and one end of the conductive plate 32 is located in the telescopic inner cavity 29, and the other end of the conductive plate 32 extends to the gap between the first gate plate 71 and the second gate plate 72. An insulating pad 33 is provided on the inner wall of the telescopic inner cavity 29, and the insulating pad 33 is located on the side close to the gap between the first gate plate 71 and the second gate plate 72. The width of the insulating pad 33 is greater than the thickness of the conductive plate 32. A side plate 30 is provided on the side of the telescopic inner cavity 29 away from the conductive plate 32, and an insulating adhesive plate 34 is provided on the conductive plate 32. A pair of plug posts 31 that slide through the side plate 30 are provided on the insulating adhesive plate 34, and a third spring 35 is sleeved on the plug posts 31.

[0043] By setting a pair of plug posts 31, the extension of the plug posts 31 can be used to determine whether the switch 7 is completely locked in place with the terminal. By setting an insulating pad 33, under the action of the third spring 35, the end of the conductive plate 32 is against the insulating pad 33. When it is not squeezed into contact with the terminal, it is in an open circuit state. When it is just squeezed into contact with the terminal, it is still in an open circuit state, thereby avoiding contact sparks. With continuous rotation, the conductive plate 32 squeezes the third spring 35, causing it to slide in the telescopic inner cavity 29, and then contacts the gate to form an electrical connection.

[0044] Example 5: Based on Example 4, the electric drive assembly is completely wrapped in the inner cavity on the side of the support frame 2, and the electric drive assembly includes a motor 38, a driven gear 36 and an insulating driving gear 37. The driven gear 36 is fixedly sleeved on the end of the electric shaft 8, and the output end of the motor 38 is connected to the insulating driving gear 37. The insulating driving gear 37 is meshed with the driven gear 36, and the motor 38 is fixed by an insulating lining 39 attached to the inner wall of the support frame 2.

[0045] By completely wrapping the electric drive assembly on the support frame 2, when a short circuit or other fault occurs in the circuit, causing the support frame 2 to be energized as a whole, the purpose of insulation protection is achieved due to the effect of the insulating lining 39. By completely wrapping, a Faraday cage is formed to protect the motor 38 inside from the influence of voltage and magnetic field.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
