Description

[0003] In existing overhead transmission lines, the connection between conductors and insulators commonly uses traditional clamps with bolt fastening as the core structure. In practical applications, the bolt fastening structure relies on regular manual maintenance and tightening. Over long-term operation, factors such as wind vibration and mechanical loads can cause the bolts to loosen, leading to a gradual decrease in conductor clamping force. When the clamping force falls below a critical value, relative slippage can occur between the conductor and the clamp, directly compromising the connection reliability. If the conductor detaches from the clamp, it can cause serious accidents such as short circuits and line breaks, directly threatening the stable power supply of the power system and the safety of surrounding facilities.

[0053] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0054] See also Figure 1 and Figure 2 As shown, according to an embodiment of this application, a locking windproof wire clamp is provided, including a support part 1, a fixing part 2, and a locking part 3; the support part 1 is fixedly mounted on an insulator 6; the fixing part 2 is fixed relative to the support part 1 and is located on the side of the support part 1 away from the insulator 6, the fixing part 2 is disposed opposite to the support part 1, and a through hole 21 is provided on the fixing part 2, the through hole 21 penetrating the fixing part 2 in the direction toward the support part 1; the locking part 3 is disposed in the through hole 21 and can move along the extension direction of the through hole 21, wherein: when no external force is applied, the locking part 3 has a tendency to move in the direction toward the support part 1 along the fixing part 2, so as to clamp the wire located between the two by the cooperation of the locking part 3 and the support part 1; under the action of external force, the locking part 3 can move away from the support part 1 to release the wire.

[0055] The locking windproof clamp provided in this embodiment automatically moves the locking part 3 to the support part 1 and clamps the conductor when there is no external force, eliminating the need for manual tightening of bolts. This avoids the loosening problem caused by vibration in traditional bolt tightening and can maintain a constant clamping force for a long time, preventing the conductor from slipping or falling off. This effectively reduces accidents such as short circuits and line breaks, ensures the safe and stable operation of the power system, and reduces the threat to surrounding facilities and personnel.

[0056] The locking windproof wire clamp provided in this embodiment can actively counteract external interference such as wind vibration and mechanical load by moving the locking part 3, so that the conductor is always in a stable clamped state, which is especially suitable for complex power transmission environments with high wind speed and multiple vibrations.

[0057] The locking windproof wire clamp provided in this embodiment allows the locking part 3 to quickly move away from the support part 1 to release the wire under external force. There is no need to repeatedly adjust the bolt torque during installation, making the operation convenient and efficient and shortening the construction time.

[0058] The locking windproof clamp provided in this embodiment eliminates easily worn parts such as bolts, thus eliminating the need for manual maintenance and bolt tightening, reducing operation and maintenance costs, and is suitable for power transmission lines in high-altitude and remote areas.

[0059] The locking windproof clamp provided in this embodiment transmits load through the rigid cooperation between the locking part 3 and the supporting part 1, resulting in a more compact structure, stronger fatigue resistance, and extended service life of the clamp.

[0060] Among them, the support part 1 serves as the base fixing part 2 of the wire clamp, which is used to connect the insulator 6 and bear the installation support function of the entire wire clamp.

[0061] Specifically, in practical applications, the support part 1 can be rigidly fixed to the top or side of the insulator 6 by means of bolts, clips or welding to ensure that the clamp and the insulator 6 form a stable whole.

[0062] In this embodiment, the fixing part 2 is fixed relative to the supporting part 1 and is located on the side of the supporting part 1 away from the insulator 6, forming a symmetrical clamping space. In this embodiment, the supporting part 1 is below and the fixing part 2 is above.

[0063] Specifically, in practical applications, the fixing part 2 can be a plate-shaped or block-shaped structure, which is fixed to the support part 1 by welding, bolting, or other methods to ensure that the relative position remains unchanged. Furthermore, a through hole 21 is provided in the middle of the fixing part 2. The axis of the through hole 21 is vertically downward and points towards the support part 1. It is used to provide a moving track for the locking part 3 and restrict its lateral displacement to ensure that the locking part 3 moves only along the axis of the through hole 21.

[0064] Among them, the locking part 3 clamps and releases the wire by moving up and down, and is the core actuator of the wire clamp.

[0065] Specifically, the locking part 3 can be a cylindrical part with a diameter slightly smaller than the inner diameter of the through hole 21, allowing it to slide freely within the through hole 21. In practical applications, when not subjected to external force, the locking part 3 can automatically move towards the support part 1 via a spring, gravity, or elastic structure. Its bottom surface and the top surface of the support part 1 together compress the wire, forming a clamping force. Since the support part 1 remains stationary, the continuous downward movement of the locking part 3 keeps the clamping force constant, counteracting external loads such as wind vibration and preventing the wire from slipping. Furthermore, when the top surface of the locking part 3 is pulled upward to overcome the spring force or gravity, causing the locking part 3 to move upward along the through hole 21, the locking part 3 moves away from the support part 1, increasing the distance between them. The wire is no longer compressed, allowing for easy removal or installation of a new wire. After the external force is removed, the locking part 3 automatically resets under the action of the spring, gravity, or elastic structure, entering the next clamping state. It is understood that, to facilitate lifting the locking part 3, a hanging ring is provided on the top surface of the locking part 3. The hanging ring can be a closed circular structure, facilitating quick hooking of tools. For example, the tool could be a hook or a wrench.

[0066] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the locking part 3 includes a locking member 31 and a first elastic member 32; the locking member 31 is inserted into the through hole 21; the first elastic member 32 is connected to the locking member 31 and is used to apply a first elastic driving force toward the support part 1 to the locking member 31 so that the locking member 31 has a tendency to move along the fixing part 2 toward the support part 1, thereby cooperating with the support part 1 to clamp the wire.

[0067] In this embodiment, by providing the first elastic element 32, an elastic driving force can be continuously provided to the locking element 31 toward the support part 1, so that the locking element 31 always maintains the tendency to move toward the support part 1. Dynamic adaptive clamping is achieved by using elastic force, avoiding the attenuation of clamping force due to factors such as vibration.

[0068] Among them, the locking member 31 is used to directly perform the clamping and releasing action of the wire and is the terminal for the transmission of mechanical force.

[0069] Specifically, the locking member 31 can be a cylinder or prism with a diameter slightly smaller than the inner diameter of the through hole 21 of the fixing part 2, and can slide freely along the axis of the through hole 21, that is, slide freely in the vertical direction. In practical applications, the locking member 31 changes the distance between itself and the supporting part 1 by moving up and down, thereby clamping or releasing the wire.

[0070] The first elastic member 32 is used to provide a continuous first elastic driving force. The direction of the first elastic driving force is towards the support part 1 of the locking member 31, so that the locking member 31 always has a downward tendency to ensure that the wire is clamped.

[0071] Specifically, see Figure 2As shown, the first elastic element 32 is a first compression spring, which is sleeved on the locking element 31. A first spring groove 211 is formed on the inner wall of the through hole 21, and a first push plate 33 is provided on the outer peripheral surface of the locking element 31. The first end of the first compression spring is fixedly connected to the first push plate 33, and the second end is fixedly connected to the bottom of the first spring groove 211 away from the support part 1. The first compression spring is used to release elastic potential energy to push the first push plate 33, causing the locking element 31 to move along the fixed part 2 towards the support part 1. Here, automatic clamping is achieved by utilizing the elastic potential energy of the first compression spring. In practical applications, when the locking element 31 is not subjected to external force, the first compression spring continuously applies a pushing force towards the support part 1 to the locking element 31 by releasing elastic potential energy, ensuring that the locking element 31 and the support part 1 always clamp the wire.

[0072] The first push plate 33 is used to receive the first elastic driving force of the first compression spring and push the locking member 31 to move.

[0073] Specifically, the first push plate 33 is annular or disc-shaped, and its surface intersects perpendicularly with the axis of the locking member 31, forming a force-bearing plane extending radially along the locking member 31. A first spring groove 211 is formed on the inner wall of the through hole 21 of the fixing part 2. This first spring groove 211 is a cylindrical groove extending axially along the through hole 21, and its axis coincides with the axis of the locking member 31. The first push plate 33 is embedded in the first spring groove 211 and slides against the inner wall of the first spring groove 211, thus limiting the movement trajectory of the first push plate 33 within the axial range of the first spring groove 211, thereby guiding the locking member 31 to move linearly along the axial direction of the through hole 21.

[0074] The first compression spring refers to a compression spring, which is sleeved on the outside of the locking member 31 to form a coaxial drive structure.

[0075] Specifically, the first end of the first compression spring is fixedly connected to the first push plate 33 of the locking member 31, such as by welding or snap-fitting, to ensure that the first elastic driving force can be effectively transmitted to the locking member 31 through the first push plate 33. The second end of the first compression spring is fixedly connected to the bottom of the first spring groove 211 on the inner wall of the through hole 21, away from the support part 1. For example, if a limiting boss or a fixing buckle is provided at the bottom of the groove, it provides a reverse support force for the first compression spring. Here, the first spring groove 211 is located inside the through hole 21 to accommodate the first compression spring and restrict its radial movement, ensuring that the first elastic driving force is transmitted axially. In practical applications, when installing the locking member 31, the locking member 31 needs to be manually pulled upward to put the first compression spring in a pre-compressed state and store elastic potential energy. At this time, the locking member 31 is away from the support part 1, and a wire installation gap is formed between the locking member 31 and the support part 1, which facilitates the insertion of the wire into the space between them. After the locking member 31 is released, the first elastic driving force generated by the pre-compression of the first compression spring is converted into an axial thrust, which pushes the first push plate 33 to move the locking member 31 toward the support part 1. At this time, the lower end face of the locking member 31 or the working surface in contact with the wire forms a clamping surface with the upper end face of the support part 1, gradually squeezing the wire until it is clamped.

[0076] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 As shown, the locking windproof clamp also includes a limiting part 4, and a limiting hole 22 is also provided on the fixing part 2. The limiting hole 22 penetrates the side wall of the fixing part 2 and communicates with the through hole 21. The limiting part 4 passes through the limiting hole 22 and can move along the extension direction of the limiting hole 22. When no external force is applied, the limiting part 4 has a tendency to move toward the locking part 3 so as to restrict the movement of the locking part 3 in the through hole 21 by cooperating with the locking part 3. Under the action of external force, the limiting part 4 can move away from the locking part 3 to release the limitation on the locking part 3, so that the locking part 3 can move along the through hole 21.

[0077] In this embodiment, when the limiting part 4 is not subjected to external force, such as in its natural state or initial installation state, its tendency to move toward the locking part 3 allows it to come into close contact with the locking part 3. At this time, the limiting part 4 restricts the movement of the locking member 31 within the through hole 21 by mechanical blocking, preventing the locking member 31 from sliding on its own due to environmental loads such as vibration and wind, thereby preventing the wire clamping force from weakening or loosening.

[0078] The limiting part 4 can be a columnar part or a block structure, with a diameter / width slightly smaller than the inner diameter of the limiting hole 22, and can slide along the axis of the limiting hole 22.

[0079] The limiting hole 22 is opened on the side wall of the fixing part 2. The axis of the limiting hole 22 intersects perpendicularly with the axis of the locking member 31. The limiting hole 22 passes through the side wall of the fixing part 2 and communicates with the through hole 21, so that the limiting part 4 can be inserted laterally into the through hole 21.

[0080] The end of the limiting part 4 near the locking part 3 can be provided as a bevel, a toothed surface or an arc-shaped surface to facilitate cooperation with the locking part 3; the other end can be provided as an operating plane, a boss or a pull ring to facilitate the application of external force.

[0081] When no external force is applied, the limiting part 4 can be driven by the elastic structure to have a tendency to move toward the locking part 3, so that the limiting part 4 automatically abuts against the locking part 3 when there is no external force.

[0082] Specifically, see Figure 2 As shown, the limiting part 4 includes a limiting member 41 and a second elastic member 42. The limiting member 41 passes through the limiting hole 22. The second elastic member 42 is connected to the limiting member 41 and applies a second elastic driving force toward the locking part 3 to the limiting member 41, so that the limiting member 41 tends to move along the limiting hole 22 toward the locking part 3, thereby cooperating with the locking part 3 and restricting the movement of the locking part 3 in the through hole 21 when no external force is applied. Under the action of external force, the second elastic member 42 is compressed, and the limiting member 41 moves away from the locking part 3 to release the limitation on the locking part 3. Here, the second elastic member 42 can continuously provide the limiting member 41 with a second elastic driving force toward the locking part 3, so that the limiting member 41 always maintains close contact with the locking part 3, and avoids the locking part 3 from loosening or mis-locking.

[0083] The limiting member 41 can be a cylindrical pin or a square pin, which passes through the limiting hole 22 of the fixing part 2 and can slide along the extending direction of the limiting hole 22. In practical applications, the end of the limiting member 41 that mates with the locking part 3 may have a bevel, groove or protrusion for mechanical engagement.

[0084] The second elastic element 42 can be a compression spring. The second elastic element 42 is used to provide a continuous second elastic driving force. The direction of the second elastic driving force is the direction of the limiting element 41 toward the locking part 3, so that the limiting element 41 always has a tendency to move toward the locking part 3, so as to achieve the purpose of restricting the movement of the locking part 3 in the through hole 21 when no external force is applied.

[0085] Specifically, see Figure 2As shown, the second elastic element 42 is a second compression spring, which is sleeved on the limiting element 41. A second spring groove 221 is formed on the inner wall of the limiting hole 22, and a second push plate 43 is provided on the outer peripheral surface of the limiting element 41. The first end of the second compression spring is fixedly connected to the second push plate 43, and the second end is fixedly connected to the bottom of the second spring groove 221 away from the locking part 3. The second compression spring is used to release elastic potential energy to push the second push plate 43, causing the limiting element 41 to move along the limiting hole 22 towards the locking part 3, so as to cooperate with the locking part 3 to restrict its movement. Here, the locking function of the limiting element 41 relies on the elastic potential energy of the second compression spring, rather than an externally applied force. Therefore, under normal working conditions, i.e., without external unlocking force, the locking part 3 is always reliably fixed by the limiting element 41, reducing the risk of unlocking due to human error or mechanism failure, and is especially suitable for long-term stable operation in outdoor high-pressure environments.

[0086] The second push plate 43 is used to receive the second elastic driving force of the second compression spring and push the limiting member 41 to move.

[0087] Specifically, the second push plate 43 is annular or disc-shaped, and its surface intersects perpendicularly with the axis of the limiting member 41, forming a force-bearing plane extending radially along the limiting member 41. A second spring groove 221 is provided on the inner wall of the limiting hole 22 of the fixing part 2. This second spring groove 221 is a cylindrical groove extending axially along the limiting hole 22, and its axis intersects perpendicularly with the axis of the locking part 3. The second push plate 43 is embedded in the second spring groove 221 and slides against the inner wall of the second spring groove 221, thus limiting the movement trajectory of the second push plate 43 within the axial range of the second spring groove 221, thereby guiding the limiting member 41 to move linearly along the axial direction of the limiting hole 22.

[0088] The second compression spring refers to a compression spring, which is sleeved on the outside of the limiting member 41 to form a coaxial drive structure.

[0089] Specifically, the first end of the second compression spring is fixedly connected to the second push plate 43 of the limiting member 41, such as by welding or snap-fitting, to ensure that the second elastic driving force can be effectively transmitted to the limiting member 41 through the second push plate 43. The second end of the second compression spring is fixedly connected to the bottom of the second spring groove 221 on the inner wall of the limiting hole 22, away from the bottom of the groove of the locking part 3. For example, if the bottom of the groove is provided with a limiting boss or a fixing buckle, it provides a reverse support force for the second compression spring. Here, the second spring groove 221 is located inside the limiting hole 22 to accommodate the second compression spring and restrict its radial movement, ensuring that the second elastic driving force is transmitted axially. In practical applications, in the initial state, the second compression spring releases the second elastic driving force, generating a thrust along the axial direction of the limiting hole 22, pushing the second push plate 43 and the limiting member 41 toward the locking part 3. At this time, the front end of the limiting member 41 engages with the limiting structure of the locking part 3, such as a groove or stepped surface, to prevent the locking part 3 from moving within the through hole 21. In the unlocked state, the limiting member 41 is pulled outward to compress the second compression spring. At this time, the limiting member 41 moves away from the locking part 3 along with the second push plate 43, and its front end disengages from the limiting structure of the locking part 3, restoring the locking part 3's ability to move freely. It can be understood that after the external force is removed, the second compression spring returns to its original deformation, pushing the limiting member 41 axially back to its original position along the limiting hole 22. At this time, the front end of the limiting member 41 re-engages with the limiting structure of the locking part 3, restoring its limiting effect on the locking part 3. Furthermore, to facilitate pulling the limiting member 41, a hanging ring is provided on the end face of the limiting member 41 away from the locking part 3. The hanging ring can be a closed circular structure, facilitating quick hooking of tools. For example, the tool can be a hook or a wrench.

[0090] In some specific examples, the limiting structure of the locking part 3 is a groove, which is set on the outer peripheral wall of the locking part 3. The front end of the limiting member 41 can be embedded in the groove. The thrust of the second compression spring makes the two lock firmly, preventing the locking part 3 from sliding or loosening in the through hole 21 due to vibration, external impact or other factors, and ensuring the connection stability of the clamp in the power transmission line.

[0091] In other specific examples, the limiting structure of the locking part 3 is a limiting tooth 311, and the front end of the limiting member 41 is provided with a stop tooth 411. See also Figure 2As shown, when the locking part 3 includes the locking member 31, the outer peripheral surface of the locking member 31 is provided with continuous limiting teeth 311 along the axial direction; the limiting teeth 311 include a first tooth surface and a second tooth surface, wherein: the first tooth surface is perpendicular to the axial direction of the locking member 31, and the second tooth surface is inclined relative to the axial direction of the locking member 31; the limiting part 4 is provided with a stop tooth 411 near the locking member 31, the stop tooth 411 includes a stop surface and a relief surface, wherein: the stop surface is perpendicular to the axial direction of the locking member 31, and is used to abut against the first tooth surface of the limiting tooth 311 when the limiting part 4 moves toward the locking part 3, so as to restrict the locking member 31 from moving away from the support part 1; the relief surface is arranged parallel to the second tooth surface, and is used to allow the locking member 31 to move along the fixing part 2 toward the support part 1 when the stop surface abuts against the first tooth surface, at which time the relief surface of the stop tooth 411 slides along the second tooth surface to avoid the movement path of the limiting tooth 311. Here, when the locking member 31 moves towards the support part 1 under the action of the first compression spring to clamp the wire, the second tooth surface of the limiting tooth 311 engages with the relief surface of the stop tooth 411, allowing them to slide relative to each other. At this time, the locking member 31 can automatically tighten progressively until the wire is fully clamped. If the wire tends to loosen due to vibration or thermal expansion and contraction, the locking member 31 tends to move away from the support part 1. At this time, the first tooth surface of the limiting tooth 311 rigidly abuts against the stop surface of the stop tooth 411, preventing the locking member 31 from moving in the opposite direction, thereby maintaining a constant clamping force and preventing the wire from loosening.

[0092] In this embodiment, the limiting member 41 cooperates with the locking member 31 to achieve one-way locking of the locking member 31.

[0093] The locking member 31 has continuous limiting teeth 311 along its length on its outer periphery. Each limiting tooth 311 includes a first tooth surface and a second tooth surface. The first tooth surface is perpendicular to the axial direction of the locking member 31 and is a horizontal plane. The second tooth surface is inclined at a certain angle relative to the axial direction of the locking member 31 and is an inclined plane.

[0094] The limiting part 4 has a stop tooth 411 on one end face near the locking member 31. The stop tooth 411 includes a stop surface and a relief surface. The stop surface is perpendicular to the axial direction of the locking member 31 and parallel to the first tooth surface. The relief surface is parallel to the second tooth surface of the limiting tooth 311, i.e., it is also inclined. The stop tooth 411 moves with the limiting member 41 within the limiting hole 22 and is driven by the second elastic member 42 to maintain contact with the locking member 31.

[0095] Specifically, in practical applications, the second elastic member 42, through a second elastic driving force, pushes the limiting member 41 towards the locking member 31, causing the stop surface of the stop tooth 411 to tightly abut against the first tooth surface of the locking member 31. When the locking member 31 attempts to move away from the support portion 1, the first tooth surface of the limiting tooth 311 generates vertical resistance against the stop surface. Since the stop surface is perpendicular to the axial direction, the two abut against each other, forming a rigid barrier that completely restricts the reverse movement of the locking member 31, achieving a one-way locking effect. When it is necessary to move the locking member 31 towards the support portion 1, the first elastic member 32, through a first elastic driving force, pushes the locking member 31 towards the support portion 1. At this time, the limiting tooth 311 of the locking member 31 moves axially, and the second tooth surface of the limiting tooth 311 contacts the relief surface of the stop tooth 411 in parallel. Since the relief surface is an inclined plane, the thrust of the locking member 31 is decomposed into a component perpendicular to the inclined plane and a component along the axial direction. The vertical component of the force compresses the second elastic element 42, causing the limiting element 41 to briefly move away from the locking element 31; the axial component of the force pushes the locking element 31 smoothly through the stop tooth 411, allowing the positioning surface to slide along the second tooth surface and avoid the movement path of the limiting tooth 311. Thus, the purpose of allowing the locking element 31 to slide freely in one direction and approach the support part 1 is achieved.

[0096] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the locking part 3 has a first fixed support surface 312 on the side surface facing the support part 1; the support part 1 has a second fixed support surface 11 on the side surface facing the locking part 3; the first fixed support surface 312 and the second fixed support surface 11 are arranged opposite to each other so that when the locking part 3 and the support part 1 are engaged, the wire is fixed by the clamping force of the first fixed support surface 312 and the second fixed support surface 11.

[0097] In some specific examples, the first fixed support surface 312 of the locking part 3 and the second fixed support surface 11 of the support part 1 are both rigid planes and are arranged relatively parallel to each other. When the two are engaged, the direct compression between the planes forms a surface contact clamping force, which can fix the wire evenly and stably, avoiding deformation or damage to the wire due to single-point force or local compression.

[0098] In other specific examples, see Figure 1 and Figure 2 As shown, the first fixed support surface 312 and the second fixed support surface 11 are curved surface structures adapted to the shape of the conductor. Compared with the planar structure, the curved surface structure can increase the contact area and avoid the insulation layer from being damaged or the conductor from being deformed due to local high voltage.

[0099] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 1As shown, the locking windproof clamp also includes a connecting part 5, which is disposed between the supporting part 1 and the fixing part 2, and is used to fix the supporting part 1 and the fixing part 2 relative to each other; wherein: one end of the connecting part 5 is fixedly connected to the supporting part 1, and the other end is fixedly connected to the fixing part 2, so as to form a clamping space for the supporting locking part 3 to move.

[0100] In this embodiment, the structure formed by the connecting part 5, the supporting part 1, and the fixing part 2 effectively defines a moving track for the locking part 3. For example, if the connecting part 5 is a rod-shaped structure, the locking part 3 can slide along the axial direction of the rod-shaped structure, that is, the depth direction of the clamping space, to ensure that when it cooperates with the supporting part 1, it only generates clamping force along the radial direction of the guide wire, thus avoiding deviation.

[0101] The connecting part 5 can be rigidly connected to the supporting part 1 and the fixing part 2 by means of welding, bolts, snaps, etc., to ensure that the supporting part 1 and the fixing part 2 will not be relatively displaced from the connecting part 5 when subjected to force.

[0102] Specifically, in practical applications, the connecting part 5, as a rigid component, can evenly transmit the force received by the supporting part 1 to the fixing part 2, preventing the supporting part 1 from deforming due to individual force, while ensuring that the moving direction of the locking part 3 is precise and controllable.

[0103] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.
