An integrated high-voltage GIS shell support cylinder assembly

Abstract

This invention relates to the field of high-voltage GIS equipment technology and discloses an integrated high-voltage GIS shell support cylinder assembly, including a support rod. A bolt is fixedly connected to the inner wall of the support rod, and a screw is threaded onto the inner wall of the bolt. When the GIS shell vibrates, the vibration frequency forces the screw to rotate, as shown in Figure 7. If the screw rotates from right to left, the screw will cause the vertical surface of the second inclined ring to press against the vertical surface of the first inclined ring, while the first inclined ring is fixed, thus restricting the rotation of the second inclined ring and the screw. When the screw drives the second inclined ring to rotate from left to right, the angle between the contact points of the second and first inclined rings is N, and the rotation tilt angle of the screw's own thread is M. This causes the screw to withstand torsional forces at two different angles during rotation, resulting in a "seizing" phenomenon, effectively preventing the screw and bolt from loosening due to external vibration.

Description

Technical Field

[0001] This invention relates to the field of high-voltage GIS equipment technology, specifically to an integrated high-voltage GIS housing support assembly. Background Technology

[0002] GIS is short for Gas Insulated Substation. In a gas insulated substation, most of the electrical equipment is sealed in a pipe tree composed of metal pipes and bushings. The inside of the pipe tree uses sulfur hexafluoride gas as the insulating medium and seals all the high-voltage electrical components inside. This is a device used in ultra-high voltage power transmission and transformation systems.

[0003] The high-voltage GIS shell primarily serves a sealing function within the substation to prevent the escape of sulfur hexafluoride gas. The support cylinder assembly used in the GIS shell contains a bolt structure, which is typically used for fine-tuning the shell's horizontal height. During high-voltage electricity transmission, the alternating magnetic field generated by the alternating current causes magnetostriction in ferromagnetic materials (such as the shell and support components), inducing vibration. This vibration can loosen the bolt structure between the support cylinder assembly and the wall, leading to downward bending of the pipes in certain areas. This bending significantly increases the pressure between the shell gaps, causing leakage at the connection joints. To address these issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an integrated high-pressure GIS shell support cylinder assembly, including a support rod, a bolt fixedly connected to the inner wall of the support rod, and a screw threadedly connected to the inner wall of the bolt, and further including:

[0005] The limiting mechanism is fixedly connected to the top of the screw and is used to clamp the outer wall of the housing;

[0006] The positioning mechanism is fixedly connected to the outer wall of the limiting mechanism and is used to limit the bolts and screws when they are subjected to vibration.

[0007] An auxiliary mechanism is fixedly connected to the inner wall of the positioning mechanism to restrict the movement of the positioning mechanism.

[0008] Before use, the support rod should be fixed to the ground, and the limiting mechanism should be fixed to the housing, ensuring that the housing is parallel to the ground.

[0009] Preferably, the limiting mechanism includes:

[0010] A rotating assembly, which is rotatably connected to the top of the screw via a support member;

[0011] The support includes a rotating groove formed in the inner wall of the screw, and a rotating rod is rotatably connected to the inner wall of the rotating groove;

[0012] The telescopic component is fixedly connected to the outer wall of the screw by a limiting member;

[0013] The limiting component includes a disc fixedly connected to the outer wall of the screw, and five slide rails fixedly connected to the bottom of the disc;

[0014] When it is necessary to adjust the level of the equipment, the operator can turn the screw, forcing the screw to rotate along the inner wall of the bolt, and the screw will drive the rotating rod to move up and down synchronously.

[0015] Preferably, the positioning mechanism includes:

[0016] The obstruction assembly is fixedly connected to the outer wall of the bolt by a limiting member;

[0017] The limiting component includes a first inclined ring fixedly connected to the outer wall of the bolt, and a second inclined ring placed on top of the first inclined ring;

[0018] The snap-fit ​​assembly is fixedly connected to the side wall of the telescopic assembly;

[0019] After the equipment is leveled, the operator can pull down the telescopic component, which will cause the inclined ring two to fit tightly against the inclined ring one.

[0020] Preferably, the auxiliary mechanism includes:

[0021] The sliding component is slidably connected to the side wall of the slide rail;

[0022] The reset assembly is fixedly connected to the outer wall of the slide rail;

[0023] When the telescopic component extends, the auxiliary mechanism will restrict the telescopic component to ensure that it can only extend outward and cannot retract.

[0024] Preferably, the rotating assembly includes a metal hoop rotatably connected to the outer wall of the rotating rod;

[0025] When using the equipment, it is necessary to ensure that the housing is inside the metal hoop and that the rotating rods at both ends are at the first level.

[0026] Preferably, the telescopic assembly includes a slide rod slidably connected to the inner wall of five slide rails, with the end of the slide rod away from the disc fixedly connected to the top of the inclined ring two;

[0027] After the second inclined ring moves downward, the screws on both sides need to be adjusted to ensure that the bottom of the second inclined ring is in close contact with the top of the first inclined ring.

[0028] Preferably, the obstruction assembly includes a retaining ring fixedly connected to the outer wall of the bolt, the outer wall of the retaining ring being fixedly connected to the bottom of the inclined ring;

[0029] When the first inclined ring and the second inclined ring are tightly attached to each other, under vibration, if the screw tends to rotate due to vibration, the screw will cause the second inclined ring to rotate clockwise through the telescopic component. The concave position of the fixed ring will restrict the rotation of the second inclined ring. When the second inclined ring rotates counterclockwise, the difference between the inclined angle of the first and second inclined rings and the screw thread angle is large, which again restricts the rotation of the second inclined ring.

[0030] Preferably, the buckle assembly includes several protruding blocks fixedly connected to the side wall of the slide bar, and the outer wall of the protruding blocks is provided with an arc-shaped groove;

[0031] When the slide bar moves the protruding block downwards, the arc-shaped groove will cause the auxiliary mechanism to deform.

[0032] Preferably, the sliding assembly includes a plurality of sliding plates slidably connected to the side wall of the slide rail, and the side wall of the sliding plates is provided with a sloping groove;

[0033] As the arc-shaped groove moves downward, the outer wall of the arc-shaped groove will press against the outer wall of the inclined groove, forcing the slide plate to move outward along the inner wall of the slide rail.

[0034] Preferably, the reset assembly includes a pull strap fixedly connected to the outer wall of the slide rail, and the end of the slide plate away from the inclined groove is fixedly connected to the inner wall of the pull strap;

[0035] The tension band is made of rubber and will accumulate potential energy after being stretched; when the arc groove presses down on the outer wall of the inclined groove, the inclined groove will extend and accumulate potential energy.

[0036] The present invention has the following beneficial effects:

[0037] (1) This invention addresses the problem that the magnetic field generated during GIS power transmission causes the housing to vibrate, leading to loosening of bolts and screws. An obstruction component is installed inside the device. After the device is leveled, the operator can pull down the second inclined ring, forcing the second inclined ring to fit tightly against the first inclined ring, resulting in the following... Figure 6 The state; where, when the GIS housing vibrates, the frequency of the vibration will force the screws to rotate, such as Figure 7 As shown, if the screw rotates from right to left, the screw will cause the vertical surface of the second inclined ring to press against the vertical surface of the first inclined ring, as... Figure 7 The T-shaped section is positioned such that the first inclined ring is fixed, thus restricting the rotation of the second inclined ring and the screw; while the screw drives the second inclined ring to rotate from left to right, as... Figure 7The angle between the two inclined rings and the first inclined ring is N, while the rotational tilt angle of the screw thread is M. This means that the screw needs to withstand torsional forces at two different angles when rotating, which can cause the screw to "get stuck". By using the above components, the screw and bolt can be effectively prevented from loosening due to external vibration.

[0038] (2) In the above application, the screw drives the inclined ring two to rotate through the telescopic component. An auxiliary mechanism is provided inside the device. When the inclined ring two moves downward, the slide rod will move downward along the inner wall of the slide rail, and the slide rod will drive the protruding block to move downward synchronously. At this time, as Figure 10 As shown, when the protruding block moves downward, the arc groove will squeeze the side wall of the inclined groove, forcing the slide plate to slide along the inner wall of the slide rail, forcing the tension belt to be in an extended state to accumulate potential energy. As the slide rod continues to move downward, after losing the push of the arc groove, part of the slide plate will be completely reset under the push of the tension belt and contact the plane of the protruding block, limiting the contraction of the slide rod. Through the application of the above components, the contraction of the slide rod due to vibration is avoided, which would affect the fit between the inclined ring two and the inclined ring one.

[0039] (3) This invention utilizes the feature of the sliding component restricting the movement of the slide rod through the buckle component, and sets the sliding component in a V-shape on the side wall of the slide rail, presenting as follows: Figure 9 In the state of R, the protruding block is elongated, which means that the protruding block will contact the sliding component at different positions during the downward movement. The protruding blocks are irregularly distributed on the outer wall of the slide bar, which means that when the protruding block slides down, one or more sliding plates will always be on top of the protruding block, restricting the return of the protruding block and the slide bar. Through the application of the above components, stepless adjustment of the equipment is achieved, and gaps between the protruding block and the sliding plate are prevented from causing internal damage due to subsequent vibration.

[0040] (4) This invention utilizes the aforementioned stepless adjustment feature by incorporating a tension belt inside the device. When the tension belt deforms, it generates potential energy, forcing multiple sliding plates to press against the protruding block, thus ensuring the inclined groove completely integrates with the outer wall of the arc-shaped groove, resulting in a shape resembling... Figure 10 At this point, multiple sliding plates will force the slide bar to move upward. The application of the above components prevents the internal parts from deforming due to the gaps in the connection when the worker pulls the slide bar downward, which would affect the equipment's ability to restrict bolts and screws.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1, please refer to Figure 1 - Figure 7 This invention relates to an integrated high-pressure GIS shell support assembly, comprising a support rod 13, a bolt 14 fixedly connected to the inner wall of the support rod 13, and a screw 15 threadedly connected to the inner wall of the bolt 14, and further comprising:

[0056] Restriction mechanism 1 is fixedly connected to the top of screw 15 and is used to clamp the outer wall of the housing;

[0057] Positioning mechanism 2 is fixedly connected to the outer wall of limiting mechanism 1 and is used to limit bolt 14 and screw 15 when they are subjected to vibration.

[0058] Auxiliary mechanism 3 is fixedly connected to the inner wall of positioning mechanism 2 and is used to restrict the movement of positioning mechanism 2;

[0059] Before use, the support rod 13 is fixed to the ground, and the limiting mechanism 1 is fixed to the housing, ensuring that the housing is parallel to the ground.

[0060] Restricted agency 1 includes:

[0061] Rotating assembly 11 is rotatably connected to the top of screw 15 via a support member;

[0062] The support includes a rotating groove 111 formed in the inner wall of the screw 15, and a rotating rod 112 is rotatably connected to the inner wall of the rotating groove 111.

[0063] Telescopic component 12 is fixedly connected to the outer wall of screw 15 by a limiting member;

[0064] The limiting component includes a disc 121 fixedly connected to the outer wall of the screw 15, and five slide rails 122 fixedly connected to the bottom of the disc 121.

[0065] When it is necessary to adjust the horizontal height of the equipment, the operator can turn the screw 15, forcing the screw 15 to rotate along the inner wall of the bolt 14, and the screw 15 will drive the rotating rod 112 to move up and down synchronously.

[0066] Positioning mechanism 2 includes:

[0067] Obstruction component 21 is fixedly connected to the outer wall of bolt 14 by a limiting member;

[0068] The limiting component includes a beveled ring 211 fixedly connected to the outer wall of bolt 14, and a beveled ring 212 is placed on top of the beveled ring 211.

[0069] The snap-fit ​​assembly 22 is fixedly connected to the side wall of the telescopic assembly 12;

[0070] To address the issue that the magnetic field generated during GIS power transmission can cause the casing to vibrate, leading to the loosening of bolts 14 and screws 15, an obstruction component 21 is installed inside the equipment. After the equipment is leveled, the operator can pull down the inclined ring 212, forcing it to fit tightly against the inclined ring 211, resulting in a state as shown in the image. Figure 6 The state.

[0071] Auxiliary mechanism 3 includes:

[0072] Sliding component 31 is slidably connected to the side wall of slide rail 122;

[0073] Reset component 32 is fixedly connected to the outer wall of slide rail 122;

[0074] When the GIS housing vibrates, the frequency of the vibration will force screw 15 to rotate, such as... Figure 7 As shown, if screw 15 rotates from right to left, screw 15 will cause the vertical surface of the inclined ring 212 to press against the vertical surface of the inclined ring 211, as... Figure 7 The T-position is maintained, while the inclined ring 211 is fixed, thus restricting the rotation of the inclined ring 212 and the screw 15; and when the screw 15 drives the inclined ring 212 to rotate from left to right, as... Figure 7 The angle between the contact position of the inclined ring 212 and the inclined ring 211 is N, while the rotation tilt angle of the screw 15's own thread is M. This means that when the screw 15 rotates, it needs to bear torsional forces at two different angles, causing the screw 15 to "get stuck". Through the application of the above components, the screw 15 and bolt 14 can be effectively prevented from loosening due to external vibration.

[0075] Example 2, please refer to Figure 3 - Figure 10 The present invention is an integrated high-pressure GIS shell support cylinder assembly. Based on Example 1, the rotating assembly 11 includes a metal hoop 113 rotatably connected to the outer wall of the rotating rod 112.

[0076] When the horizontal height of the equipment needs to be adjusted, the operator can turn screw 15, forcing screw 15 to rotate along the inner wall of bolt 14. Screw 15 will then drive rotating rod 112 and metal clamp 113 to move up and down synchronously, thus supporting the GIS housing, as shown in the figure. Figure 1 The status of G in China.

[0077] The telescopic assembly 12 includes a slide rod 123 slidably connected to the inner wall of five slide rails 122, and the end of the slide rod 123 away from the disc 121 is fixedly connected to the top of the inclined ring 212.

[0078] After the inclined ring 212 moves downward, the screws 15 on both sides need to be adjusted to ensure that the bottom of the inclined ring 212 is in close contact with the top of the inclined ring 211.

[0079] The obstruction assembly 21 includes a retaining ring 213 fixedly connected to the outer wall of the bolt 14, and the outer wall of the retaining ring 213 is fixedly connected to the bottom of the inclined ring 211.

[0080] When the first inclined ring 211 and the second inclined ring 212 are tightly attached to each other, under vibration, if the screw 15 is vibrated and tends to rotate, the screw 15 will drive the second inclined ring 212 to rotate clockwise through the telescopic component 12. The recessed position of the fixed ring 213 will restrict the rotation of the second inclined ring 212. When the second inclined ring 212 rotates counterclockwise, the angle of the inclined surface of the first inclined ring 211 and the second inclined ring 212 is significantly different from the thread angle of the screw 15, which again restricts the rotation of the second inclined ring 212.

[0081] The buckle assembly 22 includes several protruding blocks 221 fixedly connected to the side wall of the slide bar 123, and the outer wall of the protruding blocks 221 is provided with an arc-shaped groove 222;

[0082] Utilizing the aforementioned stepless adjustment feature, a tension belt 321 is installed inside the device. When the tension belt 321 deforms, it generates potential energy, forcing multiple sliding plates 311 to press against the protruding block 221. This causes the inclined groove 312 to completely engage with the outer wall of the arc-shaped groove 222, resulting in a shape resembling... Figure 10 At this time, multiple slide plates 311 will force the slide bar 123 to move upward. Through the application of the above components, it is prevented that after the worker pulls the slide bar 123 downward, the internal connecting gap will cause the protruding block 221 to hit the slide plate 311 during subsequent vibration, resulting in deformation of the internal parts and affecting the equipment's restriction of the bolt 14 and screw 15.

[0083] The sliding assembly 31 includes a plurality of slide plates 311 slidably connected to the side wall of the slide rail 122, and the side wall of the slide plate 311 is provided with a sloping groove 312.

[0084] Utilizing the feature that the sliding component 31 restricts the movement of the slide rod 123 through the latching component 22, the sliding component 31 is arranged in a V-shape on the side wall of the slide rail 122, presenting as follows: Figure 9 In the state of R, the protruding block 221 is elongated, which means that the protruding block 221 will contact the sliding component 31 at different positions during the downward movement. The protruding blocks 221 are irregularly distributed on the outer wall of the slide bar 123. This means that when the protruding block 221 slides downward, there will always be one or more slide plates 311 on top of the protruding block 221, which restricts the resetting of the protruding block 221 and the slide bar 123. Through the application of the above components, stepless adjustment of the equipment is achieved, and gaps between the protruding block 221 and the slide plate 311 are prevented from causing internal damage due to subsequent vibration.

[0085] The reset assembly 32 includes a pull belt 321 fixedly connected to the outer wall of the slide rail 122, and the end of the slide plate 311 away from the inclined groove 312 is fixedly connected to the inner wall of the pull belt 321.

[0086] In this application, the screw 15 rotates the inclined ring 212 via the telescopic assembly 12. An auxiliary mechanism 3 is installed inside the device. When the inclined ring 212 moves downwards, the slide rod 123 moves downwards along the inner wall of the slide rail 122, and the slide rod 123 drives the protruding block 221 to move downwards simultaneously. At this time, as... Figure 10 As shown, when the protruding block 221 moves downward, the arc groove 222 will squeeze the side wall of the inclined groove 312, forcing the slide plate 311 to slide along the inner wall of the slide rail 122, forcing the tension belt 321 to be in an extended state to accumulate potential energy. As the slide rod 123 continues to move downward, after losing the push of the arc groove 222, part of the slide plate 311 is completely reset under the push of the tension belt 321 and contacts the plane of the protruding block 221, restricting the contraction of the slide rod 123. Through the application of the above components, the contraction of the slide rod 123 due to vibration is avoided, which would affect the fit between the inclined ring 212 and the inclined ring 211.

[0087] One specific application of this embodiment is: before use, fix the support rod 13 to the ground to ensure that the GIS shell is inside the metal hoop 113 and that the rotating rods 112 at both ends are at the same level and the GIS shell is parallel to the ground.

[0088] When the equipment needs to be leveled, the operator can turn screw 15, forcing it to rotate along the inner wall of bolt 14. Screw 15 will then drive rotating rod 112 and metal clamp 113 to move up and down synchronously, thus supporting the GIS housing. Figure 1 The state of G in China;

[0089] To address the issue that the magnetic field generated during GIS power transmission can cause the casing to vibrate, leading to the loosening of bolts 14 and screws 15, an obstruction component 21 is installed inside the equipment. After the equipment is leveled, the operator can pull down the inclined ring 212, forcing it to fit tightly against the inclined ring 211, as shown in the image. Figure 6 The state; where, when the GIS housing vibrates, the frequency of the vibration will force screw 15 to rotate, such as Figure 7 As shown, if screw 15 rotates from right to left, screw 15 will cause the vertical surface of the inclined ring 212 to press against the vertical surface of the inclined ring 211, as... Figure 7 The T-position is maintained, while the inclined ring 211 is fixed, thus restricting the rotation of the inclined ring 212 and the screw 15; and when the screw 15 drives the inclined ring 212 to rotate from left to right, as... Figure 7 The angle between the contact position of the inclined ring 212 and the inclined ring 211 is N, while the rotation tilt angle of the screw 15's own thread is M. This means that when the screw 15 rotates, it needs to bear torsional forces at two different angles, causing the screw 15 to "get stuck". Through the application of the above components, the screw 15 and bolt 14 can be effectively prevented from loosening due to external vibration.

[0090] When utilizing the above application, the screw 15 drives the inclined ring 212 to rotate via the telescopic component 12. An auxiliary mechanism 3 is provided inside the device. When the inclined ring 212 moves downwards, the slide rod 123 moves downwards along the inner wall of the slide rail 122, and the slide rod 123 drives the protruding block 221 to move downwards synchronously. At this time, as... Figure 10 As shown, when the protruding block 221 moves downward, the arc groove 222 will squeeze the side wall of the inclined groove 312, forcing the slide plate 311 to slide along the inner wall of the slide rail 122, forcing the tension belt 321 to be in an extended state to accumulate potential energy. As the slide rod 123 continues to move downward, after losing the push of the arc groove 222, part of the slide plate 311 will be completely reset under the push of the tension belt 321 and contact the plane of the protruding block 221, limiting the contraction of the slide rod 123. Through the application of the above components, the contraction of the slide rod 123 due to vibration is avoided, which would affect the fit between the inclined ring 212 and the inclined ring 211.

[0091] Taking advantage of the feature that the sliding component 31 restricts the movement of the slide rod 123 through the snap-fit ​​component 22, the sliding component 31 is arranged in a V-shape on the side wall of the slide rail 122, presenting as follows: Figure 9In the state of R, the protruding block 221 is elongated, which means that the protruding block 221 will contact the sliding component 31 at different positions during the downward movement. The protruding blocks 221 are irregularly distributed on the outer wall of the slide bar 123. This means that when the protruding block 221 slides downward, there will always be one or more sliding plates 311 on top of the protruding block 221, which restricts the resetting of the protruding block 221 and the slide bar 123. Through the application of the above components, stepless adjustment of the equipment is achieved, and gaps between the protruding block 221 and the sliding plate 311 are prevented from causing internal damage due to subsequent vibration.

[0092] Utilizing the aforementioned stepless adjustment feature, a tension belt 321 is installed inside the equipment. When the tension belt 321 deforms, it generates potential energy, forcing multiple sliding plates 311 to press against the protruding block 221. This causes the inclined groove 312 to completely engage with the outer wall of the arc-shaped groove 222, resulting in a shape resembling... Figure 10 At this time, multiple slide plates 311 will force the slide bar 123 to move upward. Through the application of the above components, it is prevented that after the worker pulls the slide bar 123 downward, the internal connecting gap will cause the protruding block 221 to hit the slide plate 311 during subsequent vibration, resulting in deformation of the internal parts and affecting the equipment's restriction of the bolt 14 and screw 15.

The telescopic assembly (12) includes a slide rod (123) slidably connected to the inner wall of five slide rails (122), and one end of the slide rod (123) away from the disc (121) is fixedly connected to the top of the inclined ring (212); After the inclined ring 2 (212) moves downward, the screws (15) on both sides need to be adjusted to ensure that the bottom of the inclined ring 2 (212) and the top of the inclined ring 1 (211) are in close contact. The obstruction assembly (21) includes a retaining ring (213) fixedly connected to the outer wall of the bolt (14), the outer wall of the retaining ring (213) being fixedly connected to the bottom of the inclined ring (211); When the first inclined ring (211) and the second inclined ring (212) are in close contact with each other, under vibration, if the screw (15) is vibrated and has a tendency to rotate, the screw (15) will drive the second inclined ring (212) to rotate clockwise through the telescopic component (12). The recessed position of the fixed ring (213) will restrict the rotation of the second inclined ring (212). When the second inclined ring (212) rotates counterclockwise, the angle of the inclined surface of the first inclined ring (211) and the second inclined ring (212) is much different from the thread angle of the screw (15), which again restricts the rotation of the second inclined ring (212).

2. The integrated high-pressure GIS shell support assembly according to claim 1, characterized in that: The rotating assembly (11) includes a metal hoop (113) that is rotatably connected to the outer wall of the rotating rod (112). When using the equipment, it is necessary to ensure that the GIS housing is inside the metal hoop (113) and that the rotating rods (112) at both ends are at the first level.

3. The integrated high-pressure GIS shell support assembly according to claim 2, characterized in that: The buckle assembly (22) includes a plurality of protruding blocks (221) fixedly connected to the side wall of the slide bar (123), and an arc-shaped groove (222) is provided on the outer wall of the protruding blocks (221). When the slide bar (123) drives the protruding block (221) to move downward, the arc groove (222) will push the auxiliary mechanism (3) to deform.

4. The integrated high-pressure GIS shell support assembly according to claim 3, characterized in that: The sliding assembly (31) includes a plurality of sliding plates (311) slidably connected to the side wall of the slide rail (122), and the side wall of the sliding plate (311) is provided with a sloping groove (312). When the arc groove (222) moves downward, the outer wall of the arc groove (222) will squeeze the outer wall of the inclined groove (312), forcing the slide plate (311) to move outward along the inner wall of the slide rail (122).

5. The integrated high-pressure GIS shell support assembly according to claim 4, characterized in that: The reset assembly (32) includes a pull strap (321) fixedly connected to the outer wall of the slide rail (122), and the end of the slide plate (311) away from the inclined groove (312) is fixedly connected to the inner wall of the pull strap (321); Among them, the tension band (321) is made of rubber material, which will accumulate potential energy after being stretched; when the arc groove (222) presses down on the outer wall of the inclined groove (312), the inclined groove (312) will extend and accumulate potential energy.
