When the isolating switch is disconnected, the maximum relative distance between the two abutment plates and the position stability of the conductive rod after deflection are guaranteed. On the other hand, by releasing the elastic potential energy, the abutment plate can be actively and quickly driven to move, thereby suppressing the generation of electric arc and avoiding overheating of the connection between the abutment plate and the conductive rod.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0030] See also Figure 1 to Figure 11 In an embodiment of the present invention, a disconnector drive structure includes: a support frame 2, a conductive rod 4, an abutment structure, a rotating disk 13, a driven shaft 15 and a storage assembly, so that during the movement of the follower sleeve 16, the first protrusion 1601 and the first arc groove 2101, the second protrusion 1602 and the second arc groove 2201 cooperate to enable the abutment plate 7 and the conductive rod 4 to move alternately, so that when the disconnector is disconnected, the two abutment plates 7 can move first and the conductive rod 4 moves later, and when the disconnector is connected, the conductive rod 4 moves first and the abutment plate 7 moves later, thereby effectively avoiding the friction between the abutment plate 7 and the conductive rod 4 when the disconnector is operated to generate scratches, reducing the risk of hot melting at the connection between the abutment plate 7 and the conductive rod 4 when the line is connected, and improving the stability of the power supply system, as follows: The support frame 2 is provided with an inclined mounting surface 201, and the insulators 3 arranged in pairs are mounted on the inclined mounting surface 201; The conductive rod 4 is rotatably connected to a connecting member 5 provided on one of the insulators 3, wherein a limiting rod 501 is provided on the connecting member 5, and when the limiting rod 501 abuts against the conductive rod 4, the conductive rod 4 is in a state of being deflected toward the support frame 2; It should be noted that, due to the presence of the inclined mounting surface 201, the conductive rod 4 can have a tendency to move toward the abutment structure under the action of its own gravity without external interference, so that when the conductive rod 4 is connected to the abutment structure, the connection state is more stable, and when the conductive rod 4 abuts the limit rod 501, the isolating switch is in a disconnected state. At this time, the conductive rod 4 is still in a state of tilting toward the support frame 2, so that when the isolating switch is turned on, the conductive rod 4 can move first under the action of its own weight, thereby realizing the priority of the conductive rod 4 in position and then the abutment structure. It is prevented that in the process of turning on the isolating switch, friction between the end of the conductive rod 4 and the abutment structure causes scratches on the conductive rod 4, and reduces the frequency of turning on the isolating switch, causing deeper scratches on the conductive rod 4 and causing hot melting after power is turned on.

[0031] See also Figure 5~Figure 7 The abutment structure is arranged on another group of the insulators 3, and two groups of abutment plates 7 adapted to the ends of the conductive rods 4 are arranged on the abutment structure. The abutment structure comprises a bracket 6 detachably mounted on the insulator 3, and two groups of transverse rods 8 are symmetrically slidably mounted on the bracket 6, one end of the transverse rod 8 is connected to the abutment plate 7, and the other end is rotatably mounted with a groove wheel 9. Further, the abutment plates 7 and transverse rods 8 are made of conductive materials, such as iron and steel; An engaging groove is provided on the side plate 10 that is slidably connected to the bracket 6, and the groove wheel 9 can roll in the engaging groove to make the two groups of transverse rods 8 approach or move away from each other. Specifically, the side plate 10 is provided with a guide groove 1001 along its length direction, and the guide groove 1001 is slidably connected to the sliding connection part 601 provided on the bracket 6. The engaging groove includes a vertical groove 1002 and an inclined groove 1003 provided on the side plate 10, and the vertical groove 1002 is connected to the inclined groove 1003. When the groove wheel 9 rolls in the inclined groove 1003, the two groups of transverse rods 8 can approach or move away from each other.

[0032] When the groove wheel 9 is at one end of the inclined groove 1003 away from the vertical groove 1002 (the groove wheel 9 has not moved to the end of the inclined groove 1003), the transverse rod 8 can drive the corresponding two sets of abutment plates 7 to abut against the conductive rod 4. At this time, the isolating switch is in the on state. Due to the existence of the storage assembly, the side plate 10 has a tendency to continue to move away from the support frame 2, and the transverse rod 8 has a tendency to drive the two sets of abutment plates 7 to continue to move closer, thereby ensuring the fit between the abutment plates 7 and the conductive rod 4 to prevent the gap between the two from causing electric shock. Arcing causes the abutment plate 7 or the conductive rod 4 to melt. When the groove wheel 9 is in the vertical groove 1002, the two groups of abutment plates 7 are in a state of moving away from each other and separated from the conductive rod 4. At this time, the isolating switch is disconnected. Since the length direction of the transverse rod 8 is perpendicular to the length direction of the vertical groove 1002, when the isolating switch is disconnected, the transverse rod 8 has no possibility of driving the abutment plate 7 to move, thereby improving the position stability between the abutment plate 7 and the conductive rod 4 and preventing the distance between the abutment plate 7 and the conductive rod 4 from being too small, which causes arcing.

[0033] Specifically, when the isolating switch is disconnected, under the guidance of the guide groove 1001 and the sliding connection part 601, the side plate 10 will move toward the support frame 2. At this time, the groove wheel 9 can move toward the vertical groove 1002 along the length direction of the inclined groove 1003, and the groove wheel 9 can drive the transverse rod 8 to move away from the conductive rod 4 along the length direction of the transverse rod 8, so that the two abutment plates 7 can move away from each other. At this time, the abutment plate 7 can be separated from the conductive rod 4. Since the abutment plate 7 moves perpendicular to the conductive rod 4, it is ensured that when the abutment plate 7 moves, no friction will occur between the abutment plate 7 and the conductive rod 4, and thus no scratches will be caused on the fitting surface of the abutment plate 7 and the conductive rod 4.

[0034] When the isolating switch is turned on, the side plate 10 will move in the opposite direction, and the transverse rod 8 will drive the two abutment plates 7 to move closer to each other until the two abutment plates 7 abut against the conductive rod 4. Similarly, no scratches will be generated on the contact surfaces of the abutment plates 7 and the conductive rod 4.

[0035] Through the above-mentioned arrangement, when the side plate 10 moves toward or away from the support frame 2, the groove wheel 9 can drive the abutment plate 7 to move perpendicular to the conductive rod 4 by cooperating with the vertical groove 1002 and the inclined groove 1003, thereby avoiding relative friction between the abutment plate 7 and the conductive rod 4, reducing the speed of oxidation and rust between the contact surfaces of the abutment plate 7 and the conductive rod 4 due to friction and the risk of hot melting between the two.

[0036] See also Figure 4 , Figure 7The abutment structure further comprises a deflection rod 12 rotatably mounted on the support frame 2, one end of the deflection rod 12 is connected to the side plate 10 via a sleeve assembly, the sleeve assembly comprises a first straight groove 1201 arranged along the length direction of the deflection rod 12, the first straight groove 1201 is slidably fitted with a first convex shaft 11 rotatably mounted on the side of the side plate 10, and the other end is provided with the connecting groove; The rotating disk 13 is rotatably mounted on the support frame 2. In detail, the rotating disk 13 is connected to the vertical plate arranged on the support frame 2. A second cam 1301 is installed on the rotating disk 13. The second cam 1301 cooperates with a connecting groove arranged on the abutment structure, so that the abutment structure can drive the two groups of abutment plates 7 to approach or move away from each other. The connecting groove includes a second straight groove 1202 arranged on the deflection rod 12 and an arc groove 1203 connected to the second straight groove 1202. The circumferential radius of the arc groove 1203 is the same as the radius of the circular motion of the second cam 1301.

[0037] In the initial state, the second convex shaft 1301 is located at the end of the second straight groove 1202 away from the arc groove 1203, and in this state, due to the existence of the storage assembly, the second convex shaft 1301 still has the ability to follow the rotating disk 13 to make a circular downward movement (see Figure 7 ), at this time, one end of the deflection rod 12 is pressed downward, while the other end is pushed upward, so that the side plate 10 has a tendency to move upward. Under this tendency, the two abutment plates 7 can maintain a close fit with the conductive rod 4, thereby improving the connection stability between the two.

[0038] When the rotating disk 13 moves in the reverse direction, the second protruding shaft 1301 will make a circular motion in the reverse direction. At this time, the second protruding shaft 1301 will move along the length direction of the second straight groove 1202, and make the deflection rod 12 move toward one end of the rotating disk 13 away from the support frame 2. At this time, the other end of the deflection rod 12 will move toward the support frame 2, and the deflection rod 12 can drive the side plate 10 to move toward the support frame 2 through the cooperation between the first protruding shaft 11 and the first straight groove 1201, so that the two abutment plates 7 can move away from each other.

[0039] When the groove wheel 9 moves into the vertical groove 1002, the maximum relative distance between the two abutment plates 7 is reached. At this time, the second cam 1301 just moves to the end of the second straight groove 1202. In this state, the center of the arc groove 1203 is coaxial with the center of the rotating shaft of the rotating disk 13, so that when the rotating disk 13 continues to rotate, the second cam 1301 can move in the arc groove 1203, so that one end of the deflection rod 12 is locked, thereby improving the position stability between the abutment plate 7 and the conductive rod 4 in this state.

[0040] See also Figure 8~Figure 11The driven shaft 15 is rotatably mounted on the support frame 2. Specifically, the driven shaft 15 is rotatably connected to the connecting plate 20 connected to the vertical plate. The driven shaft 15 is respectively connected to the rotating shafts of the rotating disk 13 and the conductive rod 4 through a differential structure. When the driven shaft 15 rotates, the abutment plate 7 and the conductive rod 4 can be driven to alternately move. Further, one end of the driven shaft 15 is connected to the operating rod 14. The differential structure comprises a follower sleeve 16 coaxially connected to the driven shaft 15, a first driven wheel 21 is coaxially rotatably mounted on the follower sleeve 16, and the first driven wheel 21 is connected to the rotating shaft of the conductive rod 4 via a second connecting belt 24; The differential structure further includes a second driven wheel 22 rotatably connected to the driven shaft 15, wherein the second driven wheel 22 is connected to the rotating shaft of the rotating disk 13 via a first connecting belt 23, wherein the first connecting belt 23 and the second connecting belt 24 are preferably toothed belts; A first arc groove 2101 is provided on the side of the first driven wheel 21, and a second arc groove 2201 is provided on the side of the second driven wheel 22. The first protrusion 1601 and the second protrusion 1602 provided on the follower sleeve 16 are slidably matched with the first arc groove 2101 and the second arc groove 2201 respectively. It is worth noting that the central angle of the first arc groove 2101 is greater than the central angle of the second arc groove 2201. In the initial state, the first protrusion 1601 abuts against one side wall of the first arc-shaped groove 2101, and the second protrusion 1602 abuts against one side wall of the second arc-shaped groove 2201, so that in this state, the end of the conductive rod 4 can abut against the bracket 6, and the abutment plate 7 can abut against the conductive rod 4. At this time, the isolating switch is in the on state, and in the process of storing energy in the storage component, the driven shaft 15 will move and drive the follower sleeve 16 to move. At this time, the first protrusion 1601 will move along the first arc-shaped groove 2101, and the second protrusion 1602 will move along the second arc-shaped groove 2201. When the storage component actively drives the driven shaft 15 to move, since the central angle of the first arc-shaped groove 2101 is greater than the central angle of the second arc-shaped groove 2201, the second protrusion 1602 will first abut against the other side wall of the second arc-shaped groove 2201, and the second driven wheel 22 will be driven to rotate through the first connecting belt 23 The disk 13 rotates, and the two abutment plates 7 will move away from each other until the distance between the two abutment plates 7 is the largest, and the second cam 1301 moves to the end of the second straight groove 1202, and the first protrusion 1601 abuts against the other side wall of the first arc groove 2101, so that in the process of the follower sleeve 16 continuing to move, it can drive the first driven wheel 21 to rotate, and use the second connecting belt 24 to drive the conductive rod 4 to deflect. At the same time, in this process, the second cam 1301 moves in the arc groove 1203, so that the distance between the two abutment plates 7 is constant. Based on the above principle, in the process of disconnecting the isolating switch, the two abutment plates 7 will move away from each other and separate from the conductive rod 4, and then the conductive rod 4 deflects, that is, the staggered movement of the abutment plates 7 and the conductive rod 4 is realized, thereby effectively preventing the relative sliding between the abutment plates 7 and the conductive rod 4 and generating friction, thereby avoiding the generation of scratches.

[0041] After the conductive rod 4 is deflected to a certain angle, the conductive rod 4 will abut against the limit rod 501. At this time, the position of the conductive rod 4 is locked, and the conductive rod 4 is still in a state of deflection toward the support frame 2. At this time, if the isolating switch needs to be turned on, the storage component needs to be controlled to move. In the process of storing energy in the storage component, as the driven shaft 15 rotates, the conductive rod 4 can deflect in the opposite direction under the action of its own gravity, until the storage component actively drives the driven shaft 15 to move, so that the conductive rod 4 can first abut against the bracket 6, and then the two abutment plates 7 move close to each other, thereby realizing the first positioning of the conductive rod 4 and the second positioning of the abutment plate 7, and also preventing the abutment plate 7 and the conductive rod 4 from sliding relative to each other.

[0042] Through the above-mentioned arrangement, during the movement of the follower sleeve 16, the cooperation between the first protrusion 1601 and the first arc groove 2101, and the second protrusion 1602 and the second arc groove 2201 can make the abutment plate 7 and the conductive rod 4 move alternately, so that when the isolating switch is disconnected, the two abutment plates 7 can move first and the conductive rod 4 moves later, and when the isolating switch is connected, the conductive rod 4 moves first and the abutment plate 7 moves later, thereby effectively avoiding scratches caused by friction between the abutment plate 7 and the conductive rod 4 when the isolating switch is operated, reducing the risk of hot melting at the connection between the abutment plate 7 and the conductive rod 4 when the line is connected, and improving the stability of the power supply system.

[0043] It should be supplemented that in order to improve the position stability of the two abutment plates 7 when the driven shaft 15 moves to store energy in the storage assembly, a damping sleeve can be provided at the rotating shaft of the deflection rod 12 and at the connection between the side plate 10 and the sliding connection part 601. When the driven shaft 15 moves to store energy in the storage assembly, the position state between the two abutment plates 7 is more stable, thereby avoiding excessive resistance to relative movement between the second driven wheel 22 and the driven shaft 15 and the follower sleeve 16, which causes the second driven wheel 22 to directly follow the movement of the follower sleeve 16. On the one hand, it can prevent the generation of electric arcs, and on the other hand, it can avoid interference between the conductive rod 4 and the abutment plate 7 when it is reset.

[0044] See also Figure 8~Figure 9 The storage assembly is connected to the driven shaft 15, and the storage assembly can actively drive the driven shaft 15 to rotate by storing energy. The storage assembly includes two spiral grooves 1501 symmetrically arranged on the driven shaft 15, and the two spiral grooves 1501 are connected, and a protrusion 1502 is formed at the position where the two spiral grooves 1501 are connected; The driven shaft 15 is slidably sleeved with a connecting sleeve 17, and a third convex shaft 1701 is arranged in the connecting sleeve 17. The third convex shaft 1701 can slide in the two spiral grooves 1501; The storage assembly also includes an elastic telescopic rod connected to the connecting sleeve 17, and the elastic telescopic rod includes a guide shaft 1702 connected to the connecting sleeve 17 and a guide sleeve 19 slidably fitted with the guide shaft 1702, and a spring 18 is arranged between the guide shaft 1702 and the guide sleeve 19, wherein the end of the guide sleeve 19 away from the connecting sleeve 17 is connected to the connecting plate 20.

[0045] In the initial state, the spring 18 is in a stretched state, and the third cam 1701 is at one end (not the end) of one of the spiral grooves 1501 away from the protrusion 1502, so that the driven shaft 15 has a tendency to continue to rotate in one direction. Under this tendency, when the isolating switch is in the on state, it can ensure the force of the abutment plate 7 on the conductive rod 4 and the force of the conductive rod 4 on the bracket 6, so that the abutment plate 7 and the conductive rod 4 are more closely fitted, and the position of the conductive rod 4 is more stable. When the isolating switch is disconnected, it can ensure the maximum relative distance between the two abutment plates 7 and the position stability of the conductive rod 4 after deflection (in this state, one end of the conductive rod 4 is in abutment with the limit rod 501).

[0046] When the driven shaft 15 is driven to rotate by the operating rod 14, the spiral groove 1501 will rotate relative to the connecting sleeve 17, so that the third cam 1701 can move along the length direction of the spiral groove 1501. At this time, the connecting sleeve 17 moves away from the connecting plate 20, and the spring 18 is further stretched to store elastic potential energy. In this process, although the follower sleeve 16 rotates with the driven shaft 15, the first protrusion 1601 will slide in the first arc groove 2101 (this will only happen when the disconnecting switch is disconnected), and the second protrusion 1602 will slide in the second arc groove 2201, that is, in the energy storage stage, the first driven wheel 21 and the second driven wheel 22 will not rotate (the first driven wheel 21 will not rotate only when the disconnecting switch is disconnected).

[0047] After the third cam 1701 moves past the protrusion 1502, the spring 18 can release elastic potential energy and drive the follower sleeve 16 to actively move, thereby quickly driving the second driven wheel 22 to rotate, so that the two groups of abutment plates 7 can quickly perform relative movement. Through faster movement speed, the generation of arcs is reduced, avoiding overheating of the connection between the abutment plate 7 and the conductive rod 4.

[0048] Through the above arrangement, on the one hand, the position stability between the abutment plate 7 and the conductive rod 4 can be improved when the isolating switch is in the disconnected and connected states, so that when the isolating switch is connected, the abutment plate 7 and the conductive rod 4 are more closely fitted, and at the same time the position state of the conductive rod 4 is more stable. When the isolating switch is disconnected, the maximum relative distance between the two abutment plates 7 and the position stability of the conductive rod 4 after deflection are ensured. On the other hand, the elastic potential energy can be released to actively and quickly drive the abutment plate 7 to move, thereby suppressing the generation of arcs and avoiding overheating at the connection between the abutment plate 7 and the conductive rod 4.

[0049] As an embodiment of the present invention, a switch cabinet is also proposed, comprising the isolating switch driving structure as described above, and also comprising a switch cabinet body 1.
