Anti-slip distribution network line supporting fitting with bidirectional self-locking function and self-checking method of anti-slip distribution network line supporting fitting

Abstract

The invention discloses an anti-slip distribution network line supporting fitting with a bidirectional self-locking function and a self-checking method of the anti-slip distribution network line supporting fitting. The support fitting comprises a mounting structure and a self-locking device; the mounting structure comprises a tetrahedral base, and the self-locking device is used for self-locking the insulated wire when the distribution network line has a broken line fault. When the insulated wire is broken, the broken wire retracts towards one side under the action of residual tension, the insulated wire drives the eccentric wheel to rotate through friction force, and the broken wire is locked through the combined action of strong clamping force and friction force by utilizing the geometrical characteristic of the eccentric wheel and generating a self-reinforcement effect in the rotating process. The binding-free insulator can effectively solve the problem that the binding-free insulator does not have a locking function, so that a broken wire cannot be locked and fixed in a span.

Description

Technical Field

[0001] This invention belongs to the field of power transmission line technology, and in particular to a bidirectional self-locking anti-slip distribution network line support fitting and its self-verification method. Background Technology

[0002] In 10kV distribution lines, the conventional post-insulating porcelain insulators currently in use have shallow top slots, and insulated conductors are secured with binding wires. However, large-section insulated conductors are prone to detachment under various external loads, seriously threatening operational safety. To address this safety hazard of conductors detaching from the insulator slots, a structural redesign has been implemented. While ensuring the insulator's structural strength and insulation performance, an anti-detachment structure is incorporated into the insulator's structure itself, eliminating the need for binding. This binding-free insulator effectively solves the problem of insulated conductors detaching.

[0003] During the operation of overhead transmission lines, conductors may break due to severe weather, material fatigue, or external damage. However, because un-tied insulators lack an automatic locking function, the conductor may swing uncontrollably, bounce violently, or even detach from the insulator string and fall to the ground. If there are roads, farmland, buildings, or pedestrians below the line, the broken conductor could cause electric shock, posing a serious threat to human life. Summary of the Invention

[0004] The purpose of this invention is to address the deficiencies or shortcomings of the existing technology by providing a support fitting for anti-slip distribution network lines with bidirectional self-locking and self-testing functions. When an insulated conductor breaks, the broken conductor will retract to one side under residual tension. The insulated conductor drives the eccentric wheel to rotate through friction. Utilizing the geometric characteristics of the eccentric wheel, a self-amplifying force effect is generated during rotation. Through the combined action of strong clamping force and friction, the broken conductor is locked in place. This effectively solves the problem that tie-free insulators cannot lock and fix the broken conductor within a span due to the lack of locking function.

[0005] The technical solution to achieve the purpose of this invention is as follows: On the one hand, a bidirectional self-locking anti-slip distribution network line support hardware is provided, the support hardware including an installation structure and a self-locking device; the installation structure includes a tetrahedral base, and the self-locking device is used to self-lock the insulated conductor when a line breakage fault occurs in the distribution network line, the self-locking method including: immediately and continuously clamping the broken insulated conductor along the axial direction of the insulated conductor to achieve locking.

[0006] Furthermore, the self-locking device is a dual-slider mechanism, comprising a central slider and at least a pair of self-locking units;

[0007] The central slider is mounted on the tetrahedral base and can slide along the surface of the tetrahedral base, with the sliding direction along the axial direction of the insulated wire.

[0008] An insulated wire is placed on the central slider. Two self-locking units are located on both sides of the insulated wire and are in contact with it. When the insulated wire breaks, the two self-locking units clamp it immediately and continuously to achieve locking.

[0009] Each self-locking unit includes an eccentric wheel, a connecting rod, a spring, and a small slider. The eccentric wheel is mounted on the central slider and contacts the insulated wire. The small slider is mounted in a groove on a tetrahedral base and can slide within the groove. The sliding direction of the small slider is perpendicular to the sliding direction of the central slider, i.e., perpendicular to the axial direction of the insulated wire. One end of the connecting rod is connected to the eccentric wheel, and the other end is connected to the small slider via a rotatable device. The spring is mounted in the groove and is positioned along the sliding direction of the small slider. One end of the spring is connected to the small slider, and the other end is connected to the inner wall of the groove. The spring is in a compressed state and can continuously provide thrust to the small slider so that the outer surface of the eccentric wheel can maintain continuous contact with the outer surface of the insulated wire.

[0010] When the support fitting is in normal operation, the self-locking device is inactive, and the connecting rod is perpendicular to the insulated wire. When the insulated wire breaks and causes axial displacement, the friction force drives the eccentric wheel to rotate, which in turn drives the central slider to slide. At the same time, the driving force is transmitted to the connecting rod, which drives the small slider to slide along the groove through the rotatable device. The eccentric wheel generates a self-amplifying force effect during rotation, which can continuously clamp the insulated wire, thereby firmly locking the broken insulated wire.

[0011] Furthermore, the mounting structure also includes a positioning device for limiting the self-locking device, which is disposed on the upper surface of the tetrahedral base.

[0012] Furthermore, the positioning device includes at least one pair of positioning bosses, which respectively position their respective locking units.

[0013] Furthermore, the central slider slides along the first groove on the surface of the tetrahedral base, or along the second groove on the positioning boss, or simultaneously along the first groove and the second groove.

[0014] Furthermore, the support fitting also includes a first monitoring device mounted on a tetrahedral base for monitoring the displacement of the dual slider mechanism. The first monitoring device includes: a first detection unit for detecting the sliding displacement of the small slider; and a second detection unit for detecting the sliding displacement of the central slider.

[0015] Furthermore, the first detection unit includes a first displacement sensor and a first signal display device. The first displacement sensor is used to detect the sliding displacement of the small slider and transmit it to the first signal display device for display.

[0016] The second detection unit includes a second displacement sensor and a second signal display device. The second displacement sensor is used to detect the sliding displacement of the central slider and transmit it to the second signal display device for display.

[0017] Furthermore, the support fitting also includes a second monitoring device for monitoring the pressure between the eccentric wheel and the insulated wire.

[0018] Furthermore, the support fitting also includes a third monitoring device for monitoring the pressure between the small slider and the groove.

[0019] On the other hand, a self-verification method for anti-slip distribution network line support hardware is provided, the self-verification method comprising:

[0020] Multiple sets of experimental tests were conducted on the first monitoring device, and it was determined whether the sliding displacement of the small slider and the sliding displacement of the central slider satisfied the following function:

[0021]

[0022]

[0023] In the formula, y is the sliding displacement of the central slider, and x is the sliding displacement of the small slider. For the rotation angle of the eccentric wheel, It is the length from the rotatable device at one end of the connecting rod to the center of rotation of the eccentric wheel;

[0024] If the above function is satisfied, it indicates that the current support hardware meets the requirements for locking the wire; otherwise, it indicates that the current support hardware does not meet the requirements for locking the wire.

[0025] Compared with the prior art, the present invention has the following significant advantages:

[0026] (1) By utilizing the structural design of tetrahedral base, double slider mechanism, pressure sensor and displacement sensor working together, when the conductor breaks, due to the geometric characteristics of the eccentric wheel, its outline is not concentric with the rotation center. Therefore, during the rotation, the clamping force of the eccentric wheel rim on the conductor is a dynamic increasing process. By relying on the continuous rotation of the eccentric wheel to tighten and lock the conductor within a span, the strong locking force ensures that the conductor will not slip in the insulator slot, so that it is always suspended at a safe height, thus ensuring the safety of personnel and equipment below the line.

[0027] (2) This device is a purely mechanical self-locking device based on an eccentric wheel. It responds quickly, does not rely on an external power source, has strong environmental adaptability, and can operate reliably under extreme climatic conditions.

[0028] (3) The device has a self-verification function to determine whether the current manufacturing and assembly process of the device is reasonable, whether it can meet the requirements of locking the wire, and whether it needs to be remanufactured and reassembled.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0042] Furthermore, if the embodiments of this invention involve descriptions of "springs," "screws," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "springs" or "screws" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination should be considered non-existent and not within the scope of protection claimed by this invention.

[0043] In one embodiment, combined Figure 1 A bidirectional self-locking anti-slip distribution network line support hardware is provided. The support hardware includes an installation structure and a self-locking device. The installation structure includes a tetrahedral base 2. The self-locking device is used to self-lock the insulated conductor 11 when a line breakage fault occurs in the distribution network line. The self-locking method includes: clamping the broken insulated conductor 11 immediately and continuously along the axial direction of the insulated conductor 11 to achieve locking.

[0044] Furthermore, in one embodiment, combined with Figure 2 The self-locking device is a dual-slider mechanism, comprising a central slider 10 and at least a pair of self-locking units;

[0045] The central slider 10 is mounted on the tetrahedral base 2 and can slide along the surface of the tetrahedral base 2, with the sliding direction along the axial direction of the insulated wire 11.

[0046] An insulated wire 11 is placed on the central slider 10. Two self-locking units are located on both sides of the insulated wire 11 and are in contact with the insulated wire 11. When the insulated wire 11 breaks, the two self-locking units clamp it immediately and continuously to achieve locking.

[0047] Each self-locking unit includes an eccentric wheel 4, a connecting rod 5, a spring 7, and a small slider 9. The eccentric wheel 4 is mounted on the central slider 10 and contacts the insulated wire 11. The small slider 9 is mounted in a groove on the tetrahedral base 2 and can slide in the groove. The sliding direction of the small slider 9 is perpendicular to the sliding direction of the central slider 10, that is, perpendicular to the axial direction of the insulated wire 11. One end of the connecting rod 5 is connected to the eccentric wheel 4, and the other end is connected to the small slider 9 through a rotatable device. The spring 7 is mounted in the groove and is arranged along the sliding direction of the small slider 9. One end of the spring 7 is connected to the small slider 9, and the other end is connected to the inner wall of the groove. The spring 7 is in a compressed state and can continuously provide a thrust to the small slider 9 so that the outer surface of the eccentric wheel 4 can continuously contact the outer surface of the insulated wire 11.

[0048] When the support fitting is in normal operation, the self-locking device is inactive, and the connecting rod 5 is perpendicular to the insulated wire 11. When the insulated wire 11 breaks and causes axial displacement, the friction force drives the eccentric wheel 4 to rotate, which in turn drives the central slider 10 to slide. At the same time, the driving force is transmitted to the connecting rod 5, and the connecting rod 5 drives the small slider 9 to slide along the groove through the rotatable device. The eccentric wheel 4 generates a self-amplifying force effect during rotation, which can continuously clamp the insulated wire 11, thereby firmly locking the broken insulated wire 11.

[0049] Preferably, there are four self-locking units, which are distributed in a completely axially symmetrical manner with the central slider 10 as the center.

[0050] Preferably, the rotatable device adopts, but is not limited to, a hinged connection such as hinge 6.

[0051] Preferably, the other end of the spring 7 is connected to a baffle 8 that can be detachably installed in the groove, which facilitates the disassembly and installation of the spring, small slider, etc.

[0052] Furthermore, in one embodiment, the mounting structure further includes a positioning device for limiting the self-locking device, the positioning device being disposed on the upper surface of the tetrahedral base 2.

[0053] Preferably, the positioning device includes at least one pair of positioning bosses, which respectively position their respective locking units.

[0054] Preferably, the central slider 10 slides along the first groove on the surface of the tetrahedral base 2, or along the second groove 3 on the positioning boss, or simultaneously along both the first and second grooves. However, it is not limited to grooves; guide rails or other sliding structures can also be used.

[0055] Furthermore, in one embodiment, the support fitting further includes a first monitoring device mounted on the tetrahedral base 2 for monitoring the displacement of the dual slider mechanism. The first monitoring device includes: a first detection unit for detecting the sliding displacement of the small slider 9; and a second detection unit for detecting the sliding displacement of the central slider 10.

[0056] Preferably, the first detection unit includes a first displacement sensor and a first signal display device. The first displacement sensor is used to detect the sliding displacement of the small slider 9 and transmit it to the first signal display device for display.

[0057] The second detection unit includes a second displacement sensor and a second signal display device. The second displacement sensor is used to detect the sliding displacement of the central slider 10 and transmit it to the second signal display device for display.

[0058] Preferably, the first displacement sensor is installed on the inner wall of the groove where the small slider 9 is located, and the first signal display device is installed in the slot on the upper surface of the tetrahedral base 2.

[0059] Preferably, the second detection unit is installed in a slot on the upper surface of the tetrahedral base 2.

[0060] More preferably, the first displacement sensor and the second displacement sensor are capacitive displacement sensors. Combined with Figure 3 The first displacement sensor includes a first upper electrode plate 13 and a first lower electrode plate 14, which are respectively connected to two pins 15 of the first signal display device 12 via data lines 16. Figure 4 The second displacement sensor includes a second upper electrode plate 20 and a second lower electrode plate 21, which are respectively connected to two pins 18 of the second signal display device 17 via a data line 19.

[0061] Here, the main structure of the capacitive displacement sensor consists of two plates, upper and lower, connected to a signal processing and display device via a data cable. The capacitor plates have a length of L, a width of W, and a distance d between them. When the slider moves a distance x, the dielectric inside the capacitor splits into two parts: one part is air of length x with a dielectric constant of . The other part is a slider guide of length Lx, with a dielectric constant of... According to the parallel plate capacitance formula:

[0062] The capacitance of the air section is:

[0063]

[0064] The capacitance of the guide rail section is:

[0065]

[0066] The total capacitance is:

[0067]

[0068] After transformation, we can obtain:

[0069]

[0070] The above formulas show the functional relationship between the slider displacement x and the capacitor capacitance. Based on this relationship, the slider displacement can be calculated by detecting changes in capacitance.

[0071] Furthermore, in one embodiment, the support fitting also includes a second monitoring device for monitoring the pressure between the eccentric wheel 4 and the insulated wire 11.

[0072] Here, preferably, in combination Figure 5 The second monitoring device includes a first pressure sensor 22 mounted on the eccentric wheel 4, a first display terminal 25, and a first battery box 26. The first pressure sensor 22 is used to monitor the pressure between the eccentric wheel 4 and the insulated wire 11. The first display terminal 25 is used to output the pressure value in real time. The first battery box 26 is used to provide power to the first pressure sensor 22. The first pressure sensor 22 has two pins 23 at its end. One end of the pins 23 is connected to the first display terminal 25 via a data line 24, and the other end is connected to the first battery box 26.

[0073] When the central slider 10 slides, it transmits the driving force to the connecting rod and drives it to rotate synchronously. The eccentric wheel 4 at the end of the connecting rod will also rotate synchronously at a certain angle. Since the center of the eccentric wheel is not concentric with the center of rotation, the eccentric wheel exerts a squeezing effect on the insulated wire during rotation. The first display terminal 25, which is connected to the first pressure sensor 22, can output the pressure value between the eccentric wheel and the insulated wire in real time.

[0074] Furthermore, in one embodiment, the support fitting also includes a third monitoring device for monitoring the pressure between the small slider 9 and the groove.

[0075] Here, preferably, in combination Figure 6The third monitoring device includes a second pressure sensor 31 installed on the inner wall of the groove where the small slider 9 is located, a second display terminal 27, and a second battery box 29. The second pressure sensor 31 is used to monitor the pressure between the small slider 9 and the groove, the second display terminal 27 is used to output the pressure value in real time, and the second battery box 29 is used to provide power to the second pressure sensor 31. Two pins 30 are arranged above the second pressure sensor 31. One end of the pins 30 is connected to the second display terminal 27 through a data line 28, and the other end is connected to the second battery box 29.

[0076] When the central slider slides, the central slider and the connecting rod rotate. The rotatable device at one end of the connecting rod will drive the small slider to slide in the groove. When the small slider slides above the second pressure sensor 31, the second display terminal 27 displays the pressure value between the small slider and the groove.

[0077] More preferably, each pressure sensor uses a Flexiforce pressure sensor. The Flexiforce sensor is an ultra-thin and flexible printed circuit with a paper-thin structure and bendable force-measuring characteristics. It can be used to measure pressure between two surfaces, and its characteristics, linearity, hysteresis, drift, and temperature sensitivity are better than other thin-film force-measuring products, making it suitable for various installation environments. Its specific parameters are: thickness 0.208mm, length 208mm, width 14mm, accuracy 0.01N, and a maximum measurable pressure of approximately 400N.

[0078] In one embodiment, a self-verification method for anti-slip distribution network line support hardware is provided, the self-verification method comprising:

[0079] Multiple sets of experimental tests were conducted on the first monitoring device, and it was determined whether the sliding displacement of the small slider 9 and the sliding displacement of the central slider 10 satisfy the following function:

[0080]

[0081]

[0082] In the formula, y is the sliding displacement of the central slider 10, and x is the sliding displacement of the small slider 9. The angle of rotation of eccentric wheel 4, The length from the rotatable device at one end of the connecting rod 5 to the center of rotation of the eccentric wheel 4;

[0083] If the above function is satisfied, it indicates that the current support hardware meets the requirements for locking the wire; otherwise, it indicates that the current support hardware does not meet the requirements for locking the wire.

[0084] The working principle of the support fitting of the present invention will be explained below.

[0085] Combination Figure 7 Under normal operating conditions, the self-locking device is inactive, and the connecting rod is perpendicular to the insulated wire.

[0086] Combination Figure 8 When a wire break occurs above the insulated conductor, the broken conductor will retract to one side under the action of residual tension. The conductor drives the eccentric wheel to rotate through friction. Utilizing the geometric characteristics of the eccentric wheel, a self-amplifying force effect is generated during the rotation, which continuously clamps the conductor and firmly locks the broken conductor in place.

[0087] Combination Figure 9 When a wire breaks below the insulated conductor, the broken conductor will retract to one side under the action of residual tension. The conductor drives the eccentric wheel to rotate through friction. Utilizing the geometric characteristics of the eccentric wheel, a self-amplifying force effect is generated during the rotation, which continuously clamps the conductor and firmly locks the broken conductor in place.

[0088] It should be noted that for components without specific structural limitations, any component that can achieve the corresponding function in existing technology is acceptable. It should also be noted that the aforementioned settings, installations, connections, and fixations can be achieved using, but are not limited to, bolts, threads, etc. Any existing fixed or movable connection scheme can be adapted, as long as it achieves the corresponding function.

[0089] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
