[0001] The present invention relates to the technical field of opening and closing of wind power high-voltage switches, in particular to a double-action transmission device for opening and closing of wind power high-voltage switches. Background Art

[0002] Wind power high-voltage switches are key devices used to control and protect high-voltage circuits in wind power generation systems. They are primarily used for grid connection, disconnection, and fault protection of wind turbines. Currently, most existing transmission devices for opening and closing wind power high-voltage switches utilize a single-power linkage transmission method to implement opening and closing operations. This limits the control of opening and closing operations at a single wind power high-voltage switch, hindering the synchronous opening and closing operations of multiple wind power high-voltage switches and resulting in a complex distribution of the overall opening and closing transmission structure. Therefore, to address these issues, a dual-action transmission device for opening and closing wind power high-voltage switches is proposed. Summary of the Invention

[0003] The purpose of the present invention is to provide a double-acting transmission device for opening and closing a wind power high-voltage switch in order to solve the above-mentioned problem.

[0004] The present invention achieves the above-mentioned object through the following technical solutions: a double-action transmission device for opening and closing a wind power high-voltage switch, comprising two rotary disks for respectively linking an opening and closing transmission rod and an opening and closing transmission tube, a power storage assembly placed between the two rotary disks, a hexagonal rod and a clutch, a knocking hole block is installed on the annular surface of each of the two rotary disks, and a gear ring block located on one side of the rotary disk is meshedly connected with a gear, and an end of the shaft located on one side of the gear is connected to the clutch, a force-exerting portion is formed between one of the knocking hole blocks and a linkage member 1 located at the end of the opening and closing transmission rod, and another force-exerting portion is formed between the other knocking hole block and a linkage member 2 located at the end of the opening and closing transmission tube;

[0005] The force storage assembly includes a torsion spring and a follower circular plate. The same hexagonal rod is slidably installed between the hexagonal holes in the middle of the two follower circular plates. One end of the hexagonal rod is connected to a worm gear drive. One side of each follower circular plate is connected to the turntable on the same side through the torsion spring. The two torsion springs are in a mutually opposite force storage state in the same twisting and compression direction.

[0006] Preferably, the force storage assembly also includes four guide holes, guide rods and springs respectively distributed on the two follower circular plates. Each guide rod slides into two guide holes located at opposite positions, and springs are installed at both ends of the guide rod. A displacement spacing space is left between the two follower circular plates.

[0007] Preferably, the convex ring on the other side of the turntable is rotatably connected to the side plate through a bearing, and a hexagonal rod portion is inserted into the hole structure located in the middle of the turntable.

[0008] Preferably, most of the opening and closing transmission rod is located inside the opening and closing transmission tube, and a plurality of arc-shaped holes are distributed on the surface of the opening and closing transmission tube, and the opening and closing transmission rod portion exposed at each arc-shaped hole and the opening and closing transmission tube surface are distributedly installed with opening push-pull rod connecting parts.

[0009] Preferably, the bottom end portion of the linkage member 1 and the bottom end portion of the linkage member 2 are both T-shaped, and a circular hole is provided on the circular surface of one side of the linkage member 2, and the opening and closing transmission rod portion is inserted into the circular hole.

[0010] Preferably, the clutch is one of a manual clutch and an electromagnetic clutch, and the clutch controls the switching of the gear state.

[0011] Preferably, the knocking hole block rotates to the back side of the first linkage member to apply force to push, and the other knocking hole block rotates to the back side of the second linkage member to apply force to push.

[0012] The beneficial effects of the present invention are:

[0013] 1. The worm gear drive drives the hexagonal rod and the two torsion springs connected to the hexagonal rod to rotate synchronously.

It has a power source for double-acting transmission to implement opening and closing operations, and the opening and closing operations controlled by each do not interfere with each other, greatly simplifying the overly complex opening and closing transmission structure.

[0014] Second, by connecting the clutch, the restraint of the gear on the gear ring block is released, and the two torsion springs are prompted to change from the spinning and storing force state to the instantaneous spinning and expanding state, so as to achieve the effect of driving the two rotary disks to rotate instantly, which is beneficial for the two knocking hole blocks located on the two rotary disks to instantly push the linkage part 1 and the linkage part 2 respectively.

[0025] See also Figure 1-5As shown, a double-action transmission device for opening and closing a wind power high-voltage switch comprises two rotary discs 1 for respectively linking an opening and closing transmission rod 7 and an opening and closing transmission tube 8, a power storage assembly 2, a hexagonal rod 3 and a clutch 6 placed between the two rotary discs 1, a knocking hole block 120 is installed on the annular surface of each of the two rotary discs 1, and a gear ring block 110 located on one side of the rotary disc 1 is meshedly connected with a gear 5, and an end of the shaft located on one side of the gear 5 is connected to the clutch 6, a force-applying pushing portion is formed between one of the knocking hole blocks 120 and a linkage member 1 710 located at the end of the opening and closing transmission rod 7, and another force-applying pushing portion is formed between the other knocking hole block 120 and a linkage member 2 810 located at the end of the opening and closing transmission tube 8;

[0026] The force storage assembly 2 includes a torsion spring 210 and a follower circular plate 220. The same hexagonal rod 3 is slidably installed between the hexagonal holes 221 in the middle of the two follower circular plates 220. One end of the hexagonal rod 3 is connected to a worm gear drive 4. One side of each follower circular plate 220 is connected to the turntable 1 on the same side through the torsion spring 210. The two torsion springs 210 are in a mutually opposite force storage state in the same screwing and compression direction.

[0027] The power storage assembly 2 further includes four guide holes 222, guide rods 230, and springs 240, which are respectively distributed on the two follower circular plates 220. Each guide rod 230 slides through two guide holes 222 located at opposite positions, and springs 240 are mounted on both ends of the guide rods 230. A displacement spacing space is left between the two follower circular plates 220.

[0028] Combine Figure 3 As shown, when the torsion spring 210 is in a twisted compression or reset reverse rotation state, the torsion spring 210 pulls the connected follower circular plate 220 outward or pushes it inward, and at the same time, the follower circular plate 220 moves along the hexagonal rod 3 through the hexagonal hole 221.

[0029] The convex ring on the other side of the turntable 1 is rotatably connected to the side plate 10 through a bearing, and a portion of the hexagonal rod 3 is inserted into the hole structure located in the middle of the turntable 1 to prevent the hexagonal rod 3 from affecting the rotation of the turntable 1.

[0030] Most of the opening and closing transmission rod 7 is located inside the opening and closing transmission tube 8, and a plurality of arc-shaped holes 820 are distributed on the surface of the opening and closing transmission tube 8. The part of the opening and closing transmission rod 7 exposed at each arc-shaped hole 820 and the surface of the opening and closing transmission tube 8 are both distributedly installed with opening push-pull rod connectors 9, which can meet the opening and closing operation requirements of multiple wind power high-voltage switches.

[0031] Combine Figure 5As shown, the bottom end portion of the linkage member 1 710 and the bottom end portion of the linkage member 2 810 are both T-shaped, and a circular hole is provided on the circular surface of one side of the linkage member 2 810, and a portion of the opening and closing transmission rod 7 is inserted into the circular hole. The bottom end portion of the linkage member 1 710 and the bottom end portion of the linkage member 2 810 are in a T-shape, so that after the hole block 120 is knocked in its original position and does not move, the hole structure thereon touches one end of the bottom portion of the T-shape.

[0032] The clutch 6 is a manual clutch or an electromagnetic clutch, and the clutch 6 controls the switching of the state of the gear 5. The knocking hole block 120 rotates to the back of the linkage member 710 to apply force, and the other knocking hole block 120 rotates to the back of the linkage member 810 to apply force;

[0033] When the torsion spring 210 is in a twisting and storing force state and needs to drive the turntable 1 to rotate instantaneously, the clutch 6 releases the constraint on the gear 5, so that the gear 5 and the gear ring block 110 located on one side of the turntable 1 are in an unconstrained meshing connection state, and at the same time, the torsion spring 210 is turned from the twisting and storing force state to the reverse rotation state, so that the two turntables 1 are in a mutually opposite instantaneous rotation state, so as to achieve the effect of instantly applying force to the knocking hole blocks 120 located on the two turntables 1 to push the linkage part 1 710 and the linkage part 2 810 to rotate sideways, and the knocking hole blocks 120 do not move at this time to prevent the linkage part 1 710 and the linkage part 2 810 from being pushed to reset.

[0034] The specific operation steps are as follows:

[0035] Step 1: Run the worm gear drive 4 to drive the connected hexagonal rod 3 to rotate. At the same time, the gear 5 connected to the gear ring block 110 is restrained by the clutch 6. The rotation of the hexagonal rod 3 can be used to rotate the follower circular plate 220 connected via the hexagonal hole 221, so that the torsion spring 210 located between the follower circular plate 220 and the rotary disk 1 is in a twisted, compressed and force-storing state.

[0036] Step 2: Since the two torsion springs 210 are in a state of storing force in opposite directions in the same direction of rotation and compression, when the clutch 6 releases the constraint on the connected gear 5, the gear 5 no longer stops the gear ring block 110. At this time, the two torsion springs 210 in a state of storing force in opposite directions turn to a state of rotation and expansion, the hexagonal rod 3 does not move in its original position, and the two rotary disks 1 rotate in opposite directions instantly, so that the knocking hole blocks 120 on the two rotary disks 1 rotate to the back of the linkage part 1 710 and the back of the linkage part 2 810 respectively, and further drive the opening and closing transmission rod 7 and the opening and closing transmission tube 8 to rotate, respectively completing the opening of one wind power high-voltage switch and the closing of the other wind power high-voltage switch;

[0037] Step three: when it is necessary to turn one wind power high-voltage switch from open to closed and the other wind power high-voltage switch from closed to open, according to the method of storing force of the torsion spring 210 in step one, the worm gear drive 4 drives the hexagonal rod 3 in a reverse rotation state, so that the two torsion springs 210 are then turned from a free state to a twisted and compressed force storing state, wherein the twisted and compressed force storing state of the two torsion springs 210 at this time is opposite to the effect of step two. When the restraining state of the two torsion springs 210 is released, the two turntables 1 start to rotate in the opposite direction, so that the knocking hole blocks 120 located on the two turntables 1 are respectively rotated to the linkage part 1 710 to apply force to the relative back side and rotated to the linkage part 2 810 to apply force to the relative back side, thereby completing the conversion and adjustment task of turning one wind power high-voltage switch from open to closed and the other wind power high-voltage switch from closed to open.

[0038] Compared with the existing technology, the differences are:

[0039] First, the worm gear drive 4 drives the hexagonal rod 3 and the two torsion springs 210 connected to the hexagonal rod 3 to rotate synchronously, and the two torsion springs 210 are installed and distributed in opposite action states, which is conducive to the two torsion springs 210 being in a mutually opposite force storage state in the same twisting and compression direction, providing a power source for double-action transmission to implement the opening and closing actions, and the torsion spring 210 force storage operation is efficient and convenient;

[0040] Second, by connecting the clutch 6, the gear 5 releases the restraint on the gear ring block 110, prompting the two torsion springs 210 to rotate from the spinning and storing force state to the instantaneous spinning and expanding state, thereby achieving the effect of driving the two rotary disks 1 to rotate instantly. This is conducive to the two knocking hole blocks 120 located on the two rotary disks 1 to instantly push the linkage member 1 710 and the linkage member 2 810 respectively. At the same time, the opening and closing transmission rod 7 and the opening and closing transmission tube 8 rotate in different states, completing the structural function of realizing the alternating opening and closing between the two wind power high-voltage switches.
