Description

Technical Field

[0001] The utility model relates to the technical field of power transmission lines, in particular to an anti-vibration hammer. Background Art

[0002] Transmission lines erected at high altitudes are prone to mechanical vibration due to the influence of air currents, and the most frequent mechanical vibration is caused by breezes. This vibration can cause fatigue breakage of the conductors, and in severe cases, it can cause line breakage accidents, affecting the operating life of overhead transmission lines. To solve the above problems, vibration dampers are usually used to suppress breeze vibrations of conductors. The use of vibration dampers can effectively reduce the amplitude and maximum dynamic bending strain of the conductors, and improve the operating safety and service life of transmission lines. The western region of my country is located on a plateau. With the increase in altitude, the high-altitude corona problem is very prominent, and the corona effect such as corona loss caused by corona discharge will affect the safe and economic operation of transmission lines. Therefore, it is necessary to prevent corona discharge and corona noise in transmission lines in high-altitude areas.

[0003] In the prior art, the anti-vibration hammer is mainly composed of parts such as hammer head, steel strand, casing, wire clamp and bolt. Among them, the hammer head, steel strand and casing are all made of rigid materials, which are prone to corona, rust and shedding. According to a large amount of test data, the corona discharge phenomenon of conventional anti-vibration hammers is more prominent at an altitude of 1000m to 4000m, and the corona starting parts of the anti-vibration hammer are mainly concentrated at both ends of the hammer head. With the increase of altitude, its discharge intensity and corona noise also increase.

[0004] At present, the method of preventing and controlling corona in high-altitude areas of 1000m to 4000m is mainly achieved through special structural design. For example, by smoothing the arc surface of the hammer body and designing a dumbbell-shaped structure, the corona voltage is increased, the tip discharge is reduced, the overall performance is improved, and the dirty flashover is reduced. However, the two hammer heads in the dumbbell-shaped hammer head structure are one large and the other small, resulting in a larger difference in the radius of curvature of the hammer heads, which will cause the maximum field strength on the surface of the smaller hammer head to exceed the working field strength limit of the hardware surface in high-altitude areas, resulting in corona discharge; the anti-vibration hammer material is also optimized and designed, and the wire clamp material is made of austenitic non-magnetic steel. Since the wire clamp material is made of non-magnetic steel, the magnetic circuit is isolated, eliminating or reducing the power loss, but the anti-vibration hammer is only an improvement in electromagnetic loss, and does not involve the anti-corona performance and anti-vibration performance of the anti-vibration hammer.

[0005] In summary, the conventional anti-vibration hammer structure has been optimized in the prior art so that it can be used in areas with an altitude of 1000m to 4000m. However, the optimization effect is not good, and the corona problem still exists. As the altitude increases, the high-altitude corona problem becomes more prominent. Thus, the existing anti-vibration hammers (conventional anti-vibration hammers and anti-vibration hammers suitable for altitudes of 1000m to 4000m) are prone to corona problems when used in high-altitude areas above 4000m.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] In the prior art, the hammer head material of the anti-vibration hammer used for conventional lines is mostly made of gray cast iron, which has the advantages of low price and good wear resistance. However, the smoke generated during the casting process will have a serious impact on the surrounding air; the hammer head material of the anti-vibration hammer used in UHV projects is generally made of cast steel or carbon steel to improve the strength of the hammer head. In order to improve the corrosion resistance of cast iron hardware, in actual use, the above-mentioned hammer heads are all hot-dip galvanized to achieve the anti-corrosion effect. Among them, hot-dip galvanizing is a method of removing rust from iron-based metals and immersing them in high-temperature molten liquid zinc to obtain a coating. However, the hot-dip galvanizing industry is a highly polluting industry, and the plating waste liquid generated during the hot-dip galvanizing process seriously pollutes the environment; in addition, the thickness of the galvanized layer is often thin and easily damaged and falls off under the action of external mechanical forces, which easily exposes the underlying cast iron matrix, thereby reducing the corrosion resistance of the hardware.

[0033] The existing anti-vibration hammers are made of cast iron, carbon steel or cast steel, all of which are ferromagnetic materials, and they will form a closed loop around the wire. When an alternating current is passed through the wire, an alternating magnetic field will be generated around the wire, and the ferromagnetic hardware material will be repeatedly magnetized in the alternating magnetic field. Since the change of magnetic induction intensity always lags behind the change of magnetic field intensity, a hysteresis effect will be generated. Due to the repeated turning of the magnetic domain, the molecular friction inside the ferromagnetic hardware generates heat, causing hysteresis energy loss. At the same time, the alternating magnetic field generates induced electromotive force and induced current, i.e. eddy current, inside the hardware, which will further generate power loss, i.e. eddy current loss. According to research data, the power loss generated by hysteresis loss and eddy current loss in ferromagnetic hardware accounts for about 0.01% to 0.03% of the transmission capacitor. The serious power loss of traditional steel anti-vibration hammers not only brings huge energy waste and economic losses, but also the heat generated by it increases the temperature of the wire inside the anti-vibration hammer, thereby reducing its mechanical strength, thereby reducing the safety, reliability and durability of the anti-vibration hammer in long-term service.

[0034] like Figures 1 to 4 As shown, an embodiment of the utility model provides an anti-vibration hammer. The anti-vibration hammer includes a wire clamp structure 10, a stranded wire structure 20 and two hammer head structures. The stranded wire structure 20 is connected to the wire clamp structure 10; the two hammer head structures are respectively connected to the two ends of the stranded wire structure 20, and the connection position between the stranded wire structure 20 and the wire clamp structure 10 is located between the two hammer head structures. The hammer head structures are made of aluminum alloy material, and each hammer head structure includes a hammer head body 31 connected to the stranded wire structure 20 and two hemispherical hammer heads 32 connected to the hammer head body 31. The two hemispherical hammer heads 32 are respectively located on opposite sides of the stranded wire structure 20, and the curvature radius of each hemispherical hammer head 32 is greater than 50 mm.

[0035] In the above technical solution, on the one hand, the radius of curvature of the hemispherical hammer head 32 is set to be above 50 mm, the radius of curvature of the hemispherical hammer head 32 is optimized, and the surface electric field distribution of the hemispherical hammer head 32 is improved, so as to improve the anti-corona effect of the anti-vibration hammer, thereby effectively preventing the anti-vibration hammer from generating corona loss and corona noise in high-altitude areas above 4000 meters and ultra-high voltage transmission lines, so as to achieve the purpose of energy saving and environmental protection, and thus make the anti-vibration hammer meet the use of high-altitude areas above 4000 meters and ultra-high voltage transmission lines, and the test verifies that the anti-vibration hammer can On the other hand, on the basis of increasing the radius of curvature of the hemispherical hammer head 32, if the material (cast iron or cast steel) of the vibration-proof hammer in the prior art is used, it will cause the steel strand to be difficult to bear the weight of the hammer head structure, thus making it difficult to meet the breeze vibration, further leading to the failure of the vibration-proof hammer. This embodiment sets the hammer head structure to an aluminum alloy material, which can effectively reduce the weight of the hammer head structure while meeting the corona requirements of the 4,000-meter high-altitude line, thereby avoiding serious deformation of the stranded wire structure, and thus ensuring the vibration-proof performance of the vibration-proof hammer. In this way, the problem that the vibration-proof hammer in the prior art is difficult to use in high-altitude areas can be solved.

[0036] Preferably, the hammer head structure in this embodiment is made of high-strength aluminum alloy material. On the one hand, since the high-strength aluminum alloy material has excellent corrosion resistance, its corrosion resistance is much higher than that of the traditional steel hot-dip galvanized hammer head. In this way, there is no need to perform additional anti-corrosion treatment on the surface of the hammer head structure, thereby avoiding the environmental pollution caused by the hot-dip galvanizing of the traditional anti-vibration hammer; on the other hand, the hammer head is made of high-strength aluminum alloy material with low material density, which effectively reduces the weight of the anti-vibration hammer while ensuring the curvature radius of the hemispherical hammer head 32.

[0037] Specifically, in the embodiment of the utility model, the hammer head can increase the arc curvature radius of the hemispherical hammer head 32 by adopting the forging process, and in the present embodiment, the hemispherical hammer heads 32 of the two hammer head structures have the same size. In this way, the arc surface with a small curvature radius in the prior art can be removed, thereby improving the field strength and avoiding the problem of corona discharge in a smaller hammer head structure due to different sizes of the hammer head structures, thereby enhancing the anti-corona performance of the anti-vibration hammer and solving the discharge problem of the existing anti-vibration hammer in high-altitude areas above 4,000 meters.

[0038] Specifically, in the embodiment of the utility model, the wire clamp structure is made of aluminum alloy material. Since aluminum alloy material is a non-magnetic material, it can effectively reduce the line eddy current loss and further reduce the energy loss caused by the line induced current, thereby effectively reducing the energy loss during the line transmission process.

[0039] It should be noted that in order to improve the strength and wear resistance of the anti-vibration hammer, this embodiment applies the aluminum forging process to the anti-vibration hammer, and the hammer head structure adopts the solid die forging process, specifically: the aluminum rod is heated and forged into shape, thereby eliminating the casting defects such as pores and sand holes caused by the casting process of the hammer head structure of the anti-vibration hammer in the prior art, and avoiding the problems of weak plasticity, easy cracking and breakage of the cast iron anti-vibration hammer. After forging and forming, the hammer head structure is subjected to T6 and other heat treatment processes to ensure the strength and wear resistance of the hammer head structure.

[0040] Specifically, in the implementation of the present invention, the stranded wire structure is a steel stranded wire, and when the line vibrates, the hammer head structure can be vibrated, further causing the steel stranded wire to generate friction.

[0041] like Figure 3 As shown, in the embodiment of the present invention, a mounting groove is provided on the hammer body 31, and the anti-vibration hammer further includes a magnet 33 arranged in the mounting groove.

[0042] In the above technical solution, a magnet 33 is arranged in the hammer head body 31, and a magnetic field can be formed in the magnet 33. When the wire vibrates in a breeze, the anti-vibration hammer is driven to vibrate together. The anti-vibration hammer cuts the magnetic lines of force in the magnetic field. At this time, the magnetic flux in the circuit will definitely change, and an induced electromotive force will be generated in the closed circuit, thereby generating an induced current. Due to the resistance of the anti-vibration hammer, the vibration energy of the wire can be dissipated in the form of heat energy, thereby absorbing more vibration energy of the wire and improving the anti-vibration performance of the anti-vibration hammer.

[0043] Specifically, in the embodiment of the present invention, the magnet 33 is embedded in the hammer body 31 .

[0044] Preferably, in the embodiment of the present invention, the magnet 33 is a magnet or a copper rod.

[0045] like Figure 3 As shown, in the embodiment of the present invention, magnets 33 are provided on both sides of the stranded wire structure 20. In this way, the anti-vibration hammer can more effectively absorb the vibration energy of the wire, thereby effectively improving the anti-vibration performance of the anti-vibration hammer.

[0046] like Figures 3 to 8 As shown, in the embodiment of the utility model, a mounting through hole is provided on the hammer body 31, and the anti-vibration hammer further comprises a mounting cylinder 34 connected to the outer periphery of the stranded wire structure 20, and the mounting cylinder 34 is mounted in the mounting through hole. In this way, the hammer structure can be mounted on the stranded wire structure.

[0047] like Figure 3As shown, in an embodiment of the utility model, along the axis of the stranded wire structure 20, from the direction close to the wire clamp structure 10, the mounting cylinder 34 includes a first cylinder section 341, a second cylinder section 342 and a third cylinder section 343 connected in sequence, and the outer diameter of the first cylinder section 341 and the outer diameter of the third cylinder section 343 are both larger than the outer diameter of the second cylinder section 342.

[0048] Through the above-mentioned arrangement, the second barrel section 342 is mainly used for installing the stranded wire structure, and the first barrel section 341 and the third barrel section 343 can limit the second barrel section 342 to prevent the second barrel section 342 from escaping from the hammer head body 31 along the axis of the stranded wire structure, thereby making the connection between the stranded wire structure and the hammer head structure more stable, solving the problem in the prior art that the anti-vibration performance of the anti-vibration hammer is reduced due to the change in power characteristics caused by the displacement of the hammer head during the vibration of the anti-vibration hammer, thereby enabling the anti-vibration performance of the anti-vibration hammer to remain stable for a long time.

[0049] Specifically, in an embodiment of the utility model, the hammer head structure also includes a limiting portion filled in one end of the mounting through hole, and the limiting portion is located on the side of the hammer head body 31 away from the hemispherical hammer head 32. In this way, the displacement of the mounting cylinder 34 can be limited, further preventing the mounting cylinder 34 from escaping from the hammer head body 31, and also preventing the stranded wire structure 20 from extending out of the hammer head body 31.

[0050] like Figure 3 As shown, in the embodiment of the present invention, along the axis of the stranded wire structure 20, the outer diameter of the first barrel section 341 gradually decreases from the direction close to the wire clamp structure 10; and / or the outer diameter of the third barrel section 343 gradually increases. In this way, the mounting barrel 34 can be connected to the hammer body 31 in a conical shape, thereby effectively preventing the hammer structure from falling off during use.

[0051] Specifically, in the embodiment of the present invention, the installation tube 34 is riveted to the hammer body 31 to prevent the installation tube 34 from falling off the hammer body 31 .

[0052] like Figures 5 to 8 As shown, in the embodiment of the present invention, the installation cylinder 34 is riveted to the stranded wire structure 20 to prevent the stranded wire structure 20 from falling out of the installation cylinder 34 .

[0053] Preferably, in the embodiment of the present invention, the stranded wire structure and the mounting tube 34 are riveted in a regular hexagonal crimping manner. Figure 7 The middle installation cylinder 34 is a pre-crimping structure. Figure 8 The middle installation cylinder 34 is a crimped structure to hold the installation cylinder 34 tightly around the outer periphery of the stranded wire structure. In this way, the gripping force between the installation cylinder 34 and the steel strands can be enhanced to prevent the stranded wire structure 20 from escaping from the installation cylinder 34 .

[0054] like Figures 4 to 6As shown, in the embodiment of the utility model, an assembly hole connected to the mounting through hole and arranged at an angle is provided on the hammer head body 31, a positioning through hole 35 is provided on the mounting tube 34, and the anti-vibration hammer also includes a crimping member 50, one end of the crimping member 50 is located in the assembly hole, and the other end of the crimping member 50 passes through the positioning through hole 35 and abuts against the stranded wire structure 20.

[0055] Through the above-mentioned arrangement, the gripping force of the hammer head structure on the twisted wire structure can be increased. At the same time, the crimping component 50 is passed through the positioning through hole 35, which can play a positioning role and effectively prevent the hammer head structure from falling off and shifting during use, thereby solidifying the natural frequency of the anti-vibration hammer, and solving the problem in the prior art that the power characteristics of the anti-vibration hammer are changed due to the displacement of the hammer head during the vibration of the anti-vibration hammer, thereby reducing the anti-vibration performance of the anti-vibration hammer, thereby enabling the anti-vibration performance of the anti-vibration hammer to remain stable for a long time.

[0056] Specifically, in the embodiment of the utility model, an anti-dropout structure is filled in the end of the assembly hole away from the stranded wire structure, and the anti-dropout structure is located on the side of the crimping component 50 away from the stranded wire structure, so that the crimping component 50 can be prevented from falling off from the assembly hole.

[0057] like Fig. 9 and Fig.10 As shown, in the embodiment of the utility model, the wire clamp structure 10 includes: a wire clamp body 11; a wire clamp pressure cover 12, which is pivotally connected to the wire clamp body 11, one end of the wire clamp pressure cover 12 and one end of the wire clamp body 11 jointly define a clamping space for clamping the wire harness, and the other end of the wire clamp body 11 is connected to the outer periphery of the twisted wire structure 20; a clamping member 13, one end of the clamping member 13 is clamped and matched with the other end of the wire clamp pressure cover 12, and the other end of the clamping member 13 is pivotally connected to the wire clamp body 11, and the clamping member 13 has a clamping position for clamping and matching with the wire clamp pressure cover and a disengagement position detached from the wire clamp pressure cover; a first elastic member 14, which is arranged on the clamping member 13, one end of the first elastic member 14 abuts against the wire clamp body 11, and the other end of the first elastic member 14 abuts against the clamping member 13, so that the clamping member 13 is maintained in the clamping position.

[0058] Through the above arrangement, the wire clamp gland 12 and the wire clamp body 11 can be clamped together on the wire harness, and the stranded wire structure can be installed on the wire clamp structure 10 through the wire clamp body 11 to suppress breeze vibration of the wire through the anti-vibration hammer.

[0059] The wire clamp body and wire clamp cover of the vibration damping hammer in the prior art adopt a separate structure and are connected by bolts during installation. They are prone to falling during high-altitude construction, which increases the difficulty of construction. The hinge structure adopted in this embodiment connects the wire clamp cover and the wire clamp body through a hinge pin, solving the problem of easy falling of parts during high-altitude operations.

[0060] Preferably, in the embodiment of the present invention, the first elastic member 14 is a torsion spring.

[0061] Specifically, in the embodiment of the present invention, the clamping member 13 and the wire clamp body 11 are connected by bolts and nuts.

[0062] Specifically, during installation, the clamping member 13 is pressed downward, so that the clamping member 13 and the hook structure of the wire clamp gland 12 are locked and fixed, and the locking is achieved by the force of the first elastic member 14 .

[0063] like Fig. 9 and Fig.10 As shown, in the embodiment of the utility model, the anti-vibration hammer also includes: a limiting member 15, which is rotatably connected to the clamping member 13, and the limiting member 15 has a locking position that cooperates with the wire clamp pressure cover and an unlocking position that releases the cooperation with the wire clamp pressure cover; a second elastic member 16, one end of the second elastic member 16 is connected to the clamping member 13, and the other end of the second elastic member 16 is connected to the limiting member 15, so as to keep the limiting member 15 in the locked position.

[0064] Through the above arrangement, a double locking effect can be achieved, thereby improving the locking reliability of the wire clamp structure. In this way, when the clamping member 13 fails, the limiting member 15 can lock the wire clamp cover 12 to prevent the wire clamp cover 12 from falling off.

[0065] Specifically, in the embodiment of the present invention, the limiting member 15 and the clamping member 13 are connected by bolts and nuts.

[0066] Preferably, in the embodiment of the present invention, the second elastic member 16 is a torsion spring.

[0067] In high altitude, cold and oxygen-deficient areas, the installation and use of bolt-type wire clamps in the prior art requires a lot of manpower, which brings great inconvenience to the construction and increases the degree of construction danger. In this embodiment, during installation, no construction tools are needed, and the anti-vibration hammer can be quickly installed by simply depressing the clamping member 13, which greatly improves the construction and installation efficiency.

[0068] It should be noted that the embodiment of the utility model provides an anti-vibration hammer suitable for high-altitude areas above 4000m, with good anti-sickness performance and good energy-saving performance.

[0069] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: on the one hand, the curvature radius of the hemispherical hammer head is set to be above 50 mm, the curvature radius of the hemispherical hammer head is optimized, and the surface electric field distribution of the hemispherical hammer head is improved, which can improve the anti-corona effect of the anti-vibration hammer, thereby effectively preventing the anti-vibration hammer from generating corona loss and corona noise in high-altitude areas above 4000 meters and in ultra-high voltage transmission lines, so as to achieve the purpose of energy saving and environmental protection, and thus make the anti-vibration hammer meet the use of high-altitude areas above 4000 meters and ultra-high voltage transmission lines, and The test verified that the anti-vibration hammer can meet the corona and radio requirements; on the other hand, if the material (cast iron or cast steel) of the anti-vibration hammer in the prior art is used, the steel strand will be difficult to bear the weight of the hammer structure, which will make it difficult to meet the breeze vibration, and further cause the anti-vibration hammer to fail. This embodiment sets the hammer structure to an aluminum alloy material, which can effectively reduce the weight of the hammer structure while meeting the 4000-meter high-altitude line corona requirements, thereby avoiding serious deformation of the stranded wire structure, and thus ensuring the anti-vibration performance of the anti-vibration hammer. In this way, the problem that the anti-vibration hammer in the prior art is difficult to use in high-altitude areas can be solved.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
