Description

Technical Field

[0001] The utility model relates to the technical field of energy storage devices, in particular to an energy storage device for a column-mounted switch mechanism. Background Art

[0002] Pole-mounted switches are commonly found in 10kV distribution lines and are used to disconnect and connect lines. They play an important role in the power system. The reliable operation of their operating mechanisms is crucial to ensuring the stability of the power system. The energy storage device used in the pole-mounted switch mechanism utilizes the principle of mechanical transmission. It compresses the spring through rotational motion to store energy so that it can be released when needed to drive the pole-mounted switch to close or open. When storing energy, the energy storage device usually drives the energy storage handle to rotate, using a reciprocating motion within a certain range, storing energy in the clockwise direction and idling in the counterclockwise direction.

[0003] Chinese patent publication number CN215417984U discloses an energy storage device for a column-mounted switch mechanism. The device comprises a support plate, an energy storage handle, a transmission gear shaft assembly, and a first gear. The transmission gear shaft assembly includes a rotating main shaft and a second gear. The main shaft is rotatably mounted on the support plate, and the energy storage handle is used to drive the main shaft. The device features a simple structural design, easy mounting, and efficient installation, reducing production costs.

[0004] In the above-mentioned patent document, a socket is provided at one end of the energy storage handle. When the energy storage handle needs to be rotated, a support rod is usually used to insert one end of the support rod into the socket, and then the energy storage handle is rotated back and forth. However, during the rotation process, the stability between the support rod and the energy storage handle is poor, which may cause the support rod to separate from the energy storage handle, affecting the rotation of the energy storage handle, and it needs to be reinserted into the socket multiple times. Utility Model Content

[0005] The purpose of the present utility model is to solve the following shortcomings in the prior art: during the rotation process, the stability between the support rod and the energy storage handle is poor, which may cause the support rod to separate from the energy storage handle, affecting the rotation of the energy storage handle, and requiring multiple reinsertions into the socket. A column-mounted switch mechanism is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An energy storage device for a column-mounted switch mechanism includes a housing, an energy storage shaft rotatably mounted on the housing, an energy storage handle fixedly sleeved on the energy storage shaft, an insertion hole formed on an end of the energy storage handle away from the energy storage shaft, a torsion spring sleeved on the energy storage shaft, and two ends of the torsion spring fixedly connected to the housing and the energy storage handle, respectively;

[0008] A rotating ring is rotatably installed in the jack. On one side of the rotating ring close to the body shell, a plurality of elastic rods are fixedly installed obliquely. The plurality of elastic rods are arranged equidistantly in a circumferential manner on one side of the rotating ring. A conical ring is installed in the inner ring of the rotating ring through a sliding assembly. The conical ring is in sliding contact with the plurality of elastic rods. A transmission assembly is provided on the body shell for driving the conical ring to move towards the body shell.

[0009] Preferably, the sliding assembly includes a plurality of fixing blocks fixedly installed on the inner ring wall of the rotating ring, a plurality of moving rods fixedly installed at one end of the conical ring, and a plurality of stoppers respectively fixedly installed at one end of the plurality of moving rods. A moving hole is formed in the fixing block, and the moving rod is slidably inserted into the moving hole.

[0010] Preferably, the transmission assembly includes an arc-shaped fixed seat fixedly installed on the body shell, an L-shaped top block fixedly installed on the arc-shaped fixed seat, and an inclined plate fixedly installed obliquely on the conical ring.

[0011] Preferably, an arc-shaped groove is formed in the arc-shaped fixed seat. The center of the arc-shaped groove coincides with the axis of the energy storage shaft. A slider is slidably installed in the arc-shaped groove. An L-shaped connecting block is fixedly installed on the slider. One end of the connecting block is fixedly connected to the energy storage handle. A positioning groove is formed in the slider.

[0012] Preferably, resistance blocks are fixedly installed at one ends of the plurality of elastic rods, and anti-slip pads are fixedly installed on the plurality of resistance blocks.

[0013] Preferably, the L-shaped top block is located on the moving path of the inclined plate, and the elastic potential energy of the torsion spring is greater than the elastic potential energy of the elastic rod.

[0014] In the present utility model, the beneficial effects are as follows:

[0015] 1. When it is necessary to rotate the energy storage handle, insert one end of the support rod into the jack, and then through the mutual cooperation of the rotating ring, the transmission assembly, the sliding assembly, the conical ring and the elastic rod, the support rod is clamped and limited, ensuring the stability between the support rod and the energy storage handle, effectively preventing one end of the support rod from disengaging from the jack, enabling it to stably drive the energy storage handle to rotate, and eliminating the need to repeatedly insert one end of the support rod into the jack.

[0016] 2. When one end of the support rod is inserted into the jack, it is simultaneously inserted into the positioning groove formed in the slider. When the support rod drives the energy storage handle to rotate, through the mutual cooperation of the arc-shaped fixed seat, the arc-shaped groove and the slider, the one end of the support rod can be supported, reducing the shaking of the support rod during rotation, thereby further improving the stability between the support rod and the energy storage handle.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Referring to Figures 1 - 5 , an energy storage device for a pole-mounted switch mechanism includes a body housing (1), an energy storage shaft (2) is rotatably installed on the body housing (1), an energy storage handle (3) is fixedly sleeved on the energy storage shaft (2), a jack is provided at one end of the energy storage handle (3) away from the energy storage shaft (2), a torsion spring (4) is sleeved on the energy storage shaft (2), and both ends of the torsion spring (4) are fixedly connected to the body housing (1) and the energy storage handle (3) respectively.

[0025] When storing energy, one end of the support rod is inserted into the jack, the support rod is pulled downward to drive the energy storage handle (3) to rotate clockwise for energy storage. Then, when the support rod moves upward, under the action of the torsion of the torsion spring (4), the energy storage handle (3) automatically rotates counterclockwise.

[0026] A rotating ring 5 is rotatably installed inside the jack. On one side of the rotating ring 5 close to the body shell 1, multiple elastic rods 6 are fixedly installed obliquely. The multiple elastic rods 6 are arranged circumferentially and equidistantly on one side of the rotating ring 5. A conical ring 7 is installed inside the inner ring of the rotating ring 5 through a sliding assembly. The sliding assembly includes multiple fixing blocks 8 fixedly installed on the inner ring wall of the rotating ring 5, multiple moving rods 9 fixedly installed at one end of the conical ring 7, and multiple stoppers 10 respectively fixedly installed at one end of the multiple moving rods 9. A moving hole is formed in the fixing block 8, and the moving rod 9 is slidably inserted into the moving hole. The conical ring 7 is in sliding contact with the multiple elastic rods 6. A transmission assembly is provided on the body shell 1 for driving the conical ring 7 to move towards the body shell 1.

[0027] The conical ring 7 is slidably installed on the rotating ring 5 through the fixing blocks 8, moving rods 9 and stoppers 10. The axis of the conical ring 7 coincides with the axis of the rotating ring 5.

[0028] In the initial state, the end of the energy storage handle 3 with the jack is located at the uppermost position. At this time, under the action of the transmission assembly, the conical ring 7 has a tendency to move towards the body shell 1. The conical ring 7 contacts the multiple elastic rods 6, causing one end of the elastic rods 6 to deform and bend away from the conical ring 7. When one end of the support rod is inserted into the jack, one end of the support rod passes through the conical ring 7 and also passes through the multiple elastic rods 6. Then, the support rod is pulled downward, driving the energy storage handle 3 to rotate clockwise. When the energy storage handle 3 rotates clockwise, the tendency of the conical ring 7 to move towards the body shell 1 disappears. At this time, under the elastic force of the elastic rods 6, the ends of the multiple elastic rods 6 away from the rotating ring 5 approach the support rod and contact the support rod, playing a role of clamping and limiting the support rod, ensuring the stability between the support rod and the energy storage handle 3. At the same time, a large frictional force is generated with the support rod. Under the action of the frictional force, the end of the support rod can be prevented from being pulled out of the jack, enabling it to stably drive the energy storage handle 3 to rotate without repeatedly inserting the end of the support rod into the jack.

[0029] The transmission assembly includes an arc-shaped fixed seat 11 fixedly installed on the body shell 1, an L-shaped top block 12 fixedly installed on the arc-shaped fixed seat 11, and an inclined plate 13 fixedly installed obliquely on the conical ring 7. The L-shaped top block 12 is located on the moving path of the inclined plate 13. The elastic potential energy of the torsion spring 4 is greater than the elastic potential energy of the elastic rod 6. Under the action of the torsion of the torsion spring 4, the energy storage handle 3 drives the conical ring 7 to have a tendency to rotate counterclockwise. As a result, one end of the L-shaped top block 12 installed on the arc-shaped fixed seat 11 will contact the inclined plate 13. Under the action of the inclined plate 13, the conical ring 7 has a tendency to move towards the body shell 1. When the energy storage handle 3 rotates clockwise, the L-shaped top block 12 separates from the inclined plate 13. At this time, the elastic rods 6 will approach the support rod under the action of the elastic force.

[0030] An arc-shaped fixed seat 11 is provided with an arc-shaped groove 14. The center of the arc-shaped groove 14 coincides with the axis of the energy storage shaft 2. A slider 15 is slidably installed in the arc-shaped groove 14. An L-shaped connecting block 16 is fixedly installed on the slider 15. One end of the connecting block 16 is fixedly connected to the energy storage handle 3. A positioning groove is provided on the slider 15. The slider 15 can slide in the arc-shaped groove 14. When the energy storage handle 3 rotates, the slider 15 can be driven by the connecting block 16 to rotate around the energy storage shaft 2 in the arc-shaped groove 14. When one end of the support rod is inserted into the jack, at the same time, one end of the support rod is inserted into the positioning groove provided on the slider 15, which can play a supporting role for one end of the support rod, reduce the shaking of the support rod during the rotation process, and thus further improve the stability between the support rod and the energy storage handle 3.

[0031] One end of each of a plurality of elastic rods 6 is fixedly installed with a resistance block 17, and anti-slip pads are fixedly installed on the plurality of resistance blocks 17. When one end of the elastic rod 6 contacts the support rod, the resistance block 17 will further increase the frictional force between the elastic rod 6 and the support rod.

[0032] In the present utility model, in the initial state, the conical ring 7 has a tendency to move towards the body shell 1. The conical ring 7 contacts the plurality of elastic rods 6, causing one end of the elastic rod 6 to deform and bend away from the conical ring 7. When one end of the support rod is inserted into the jack, one end of the support rod passes through the conical ring 7 and at the same time passes through the plurality of elastic rods 6, and then the support rod is pulled downward to drive the energy storage handle 3 to rotate clockwise. When the energy storage handle 3 rotates clockwise, the tendency of the conical ring 7 to move towards the body shell 1 disappears. At this time, under the elastic force of the elastic rod 6, the ends of the plurality of elastic rods 6 away from the rotating ring 5 approach the support rod and contact the support rod, playing a role of clamping and limiting the support rod, ensuring the stability between the support rod and the energy storage handle 3, and at the same time generating a large frictional force with the support rod. Under the action of the frictional force, it can prevent one end of the support rod from being pulled out of the jack, enabling it to stably drive the energy storage handle 3 to rotate without having to insert one end of the support rod into the jack again multiple times.

[0033] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
