Description

Technical Field

[0001] The present invention relates to the technical field of vibration damping hammers, and specifically to an energy-saving vibration damping hammer that is easy to install. Background Technique

[0002] In the field of power transmission, overhead conductors often face vibration problems caused by factors such as wind. During the installation process of traditional vibration damping hammers, operators often need to use a variety of complex tools and spend a lot of time and energy on cumbersome debugging and fixing. The installation efficiency is low, and the installation effect is greatly affected by human factors. Moreover, conventional vibration damping hammers have relatively single functions, only focusing on suppressing conductor vibration and having no relevant considerations for energy conservation. With the continuous improvement of the requirements for high efficiency and energy conservation in the power industry, it is urgent to develop a vibration damping hammer that is both easy to install and has energy-saving characteristics. Currently, there is an urgent need in the market for a vibration damping hammer product that can simplify the installation process, reduce installation costs, and at the same time achieve the purpose of energy conservation on the basis of suppressing conductor vibration to meet the growing needs of the power system.

[0003] A vibration damping hammer that is easy to install with the patent publication number CN108599071A achieves the purpose of more conveniently and quickly clamping the wire through a slider and a baffle. However, the energy-saving vibration damping hammer has the following defects in addition to the installation convenience.

[0004] First of all, while the energy-saving vibration damping hammer is easy to install, it also needs to have an anti-loosening effect. After being fixed and installed by bolts, the existing vibration damping hammer is prone to loosening under vibration; secondly, the energy-saving vibration damping hammer has high requirements for energy conservation. Energy conservation can be achieved by improving the elasticity and lifespan of the vibration damping hammer, or by strengthening the utilization of the vibration energy of the vibration damping hammer.

A vibration power generation device is provided in the sliding grooves of the hanging rod and the top rod. The vibration power generation device includes piezoelectric ceramics and a power source;

[0010] When the cable is static, the spring provides an upward elastic force for the top plate, thereby increasing the clamping force on the cable.

An electromagnetic device is also arranged in the sliding grooves of the hanging rod and the top rod. The electromagnetic device is connected to the power source. When the current sensor detects that the current exceeds a preset value, the electromagnetic device is started to repel or attract the magnetic block to slide downward, that is, to increase the elastic force of the spring on the hanging rod when the vibration amplitude is too large.

[0012] Preferably, a base is arranged at the top of the sliding grooves of the hanging rod and the top rod. The top of the base supports the bottom of the top plate.

Internal threads are arranged in the through holes of the upward sliding block and the downward sliding block. The upper threaded section is threadedly connected to the upward sliding block, and the lower threaded section is threadedly connected to the downward sliding block. The threads on the upper threaded section and the lower threaded section have opposite directions. When the double-headed screw is rotated, the pressing plate and the base move in opposite directions, and at the same time, the tightness of the spring is automatically adjusted according to the radius of the cable.

[0013] Preferably, the piezoelectric ceramics are arranged at any at least one of the contact surface between the spring and the hanging rod, the contact surface between the spring and the top rod, or the middle internal position of the spring.

[0014] Preferably, the thread pitch of the upper threaded section is greater than that of the lower threaded section. When the double-headed screw is rotated, the moving speed of the pressing plate is greater than that of the base. The opening position of the locking groove is set at a position slightly above the side surface of the main clamp body, so that when the pressing plate and the top plate clamp the cable, the cable is located at a position lower than the opening of the locking groove.

[0016] Preferably, the main clamp body and the vertical plate are made of aluminum alloy, the hammer head is made of zinc alloy, and the elastic connecting rod is a steel cable.

The control circuit controls the magnitude and direction of the energizing current of the electromagnet according to the change in the current detected by the current sensor, so as to precisely adjust the magnitude of the repulsive force or attractive force on the magnetic block, and realize the stepless adjustment of the spring force.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides an energy-saving anti-vibration hammer that is easy to install and has the following beneficial effects:

[0022] 1. For the installed energy-saving anti-vibration hammer, by arranging a pressing plate for clamping the cable downward above the locking groove, a top plate for pressing the cable upward below, a hanging rod with its top sliding in the main clamp body above the vertical plate, and a top rod with its bottom sliding in the main clamp body at the bottom of the top plate, and connecting the end of the hanging rod and the top rod with a spring, the double adjustment of the clamping force on the cable and the spring force of the hammer head is realized. When the cable is static, the spring provides an upward spring force for the top plate, so that the top plate tightly presses against the cable and works together with the upper pressing plate above to effectively enhance the clamping force on the cable, preventing the anti-vibration hammer from displacing or falling off under static conditions. When the cable vibrates, the spring provides a downward elasticity for the vertical plate, and the vertical plate drives the hammer head to move, indirectly increasing the spring force of the hammer head, enabling the hammer head to more powerfully suppress the vibration of the cable. At the same time, when the hanging rod bounces up and down, it reciprocally presses the vibration power generation device to generate electric energy, realizing the recycling of energy, achieving multiple effects of improving the working stability of the anti-vibration hammer, enhancing the anti-vibration effect, and saving energy.

[0023] 2. The installed energy-saving vibration damper realizes automatic adjustment of the spring elasticity according to the vibration amplitude by fixedly connecting a magnetic block to the spring, arranging a current sensor on the transmission wire between the piezoelectric ceramic and the power supply, and arranging an electromagnetic device in the sliding groove where the hanging rod and the top rod slide. The electromagnetic device is connected to the power supply. When the current sensor detects that the current exceeds the preset value, which indicates that the vibration amplitude of the cable is too large, the electromagnetic device is activated. By repelling or attracting the magnetic block to slide downward, the elastic coefficient of the spring is changed, thereby increasing the elastic force of the spring on the hanging rod. This design can automatically enhance the supporting force of the spring on the vertical plate and the hammer head during severe vibration, enabling the hammer head to more effectively suppress excessive vibration and prevent the cable from being damaged due to excessive vibration, achieving the effects of adaptive adjustment, precise vibration prevention, and cable protection, and greatly improving the working performance of the vibration damper under different vibration conditions.

[0024] 3. The installed energy-saving vibration damper realizes automatic adjustment of the spring tightness according to the cable radius by arranging a base at the top of the sliding groove where the hanging rod and the top rod slide, supporting a top plate on the top of the base, fixedly connecting a lower slider to the base, fixedly connecting an upper slider to the pressing plate, arranging a clamping device on the outer side of the main clamp body, arranging a vertical double-headed screw on the clamping device, with the upper half of the double-headed screw being an upper threaded section passing through the upper slider and the lower half being a lower threaded section passing through the lower slider, and the thread directions of the upper threaded section and the lower threaded section being opposite. When the double-headed screw is rotated, due to the opposite thread directions of the upper threaded section and the lower threaded section, the upper slider and the lower slider will move in opposite directions, thereby driving the pressing plate and the base to move in opposite directions. In this way, the distance between the pressing plate and the top plate in the locking groove can be flexibly adjusted according to cables of different radii, and at the same time, the tightness of the spring can also be adjusted accordingly. It achieves the effects of improving the versatility of the vibration damper, facilitating installation, and optimizing the vibration prevention performance, enabling the vibration damper to better adapt to various specifications of cables and improving the working efficiency.

[0042] Embodiment 1:

[0043] This embodiment provides an energy-saving anti-vibration hammer that is easy to install and has the following technical features.

[0044] Please refer to Figures 1-10 , an energy-saving anti-vibration hammer that is easy to install, including a main clamp body 1. A locking groove 11 for clamping a cable 9 is provided on the main clamp body 1. A vertical plate 2 is connected below the main clamp body 1. Two hammer heads 4 are connected at both ends of the vertical plate 2 through an elastic connecting rod 3. Above the locking groove 11, a pressing plate 12 for clamping the cable 9 downward is provided. Below the locking groove 11, a top plate 13 for supporting the cable 9 upward is provided. Above the vertical plate 2, a hanging rod 21 with its top end sliding inside the main clamp body 1 is provided. At the bottom of the top plate 13, a top rod 131 with its bottom end sliding inside the main clamp body 1 is provided. A spring 22 is provided between the end of the top rod 131 and the hanging rod 21. A vibration power generation device is provided in the sliding chute of the hanging rod 21 and the top rod 131. The vibration power generation device includes piezoelectric ceramics and a power source;

[0045] When the cable 9 is static, the spring 22 provides an upward elastic force to the top plate 13, thereby increasing the clamping force on the cable 9. When the cable 9 vibrates, the spring 22 provides a downward elasticity to the vertical plate 2, thereby indirectly increasing the elastic force of the hammer head 4. And when the hanging rod 21 bounces up and down, it reciprocally presses the vibration power generation device to generate electric energy.

[0046] It should be noted that the power source is a rechargeable battery. The electric energy generated by the vibration power generation device is charged to the rechargeable battery through a charging management circuit. The charging management circuit has overcharge protection and over-discharge protection functions to extend the service life of the rechargeable battery.

[0047] Furthermore, a magnetic block 23 is fixedly connected to the spring 22. The magnetic block 23 is arranged at the middle position in the vertical direction of the spring 22. A current sensor is provided on the power transmission wire between the piezoelectric ceramics and the power source. An electromagnetic device is also provided in the sliding chute of the hanging rod 21 and the top rod 131. The electromagnetic device is connected to the power source. When the current sensor detects that the current exceeds a preset value, the electromagnetic device is activated to repel or attract the magnetic block 23 to slide downward, that is, to increase the elastic force of the spring 22 on the hanging rod 21 when the vibration amplitude is too large.

[0048] It should be noted that when the magnetic block 23 slides downward, the upper half of the spring 22 is stretched and the lower half is compressed. The hanging rod 21 is connected to the lower half of the spring 22. Therefore, the elastic force on the hanging rod 21 can be increased, so that when the vibration amplitude of the cable 9 is too large, the increasing speed of the vibration amplitude of the hanging rod 21 can be reduced, and the piezoelectric ceramics can be prevented from being damaged due to the too large amplitude of the hanging rod 21.

[0049] Furthermore, a base 14 is arranged at the top inside the chute where the hanging rod 21 slides with the ejector rod 131. The top of the base 14 supports the bottom of the top plate 13. A lower slider 141 is fixedly connected to the base 14, and an upper slider 121 is fixedly connected to the pressing plate 12. A clamping device 15 is arranged outside the main clamp body 1. A vertical double-headed screw 151 is arranged on the clamping device 15. The upper half of the double-headed screw 151 is an upper threaded section 1511 passing through the upper slider 121, and the lower half is a lower threaded section 1512 passing through the lower slider 141. External threads are arranged on the upper threaded section 1511 and the lower threaded section 1512, and internal threads are arranged in the through holes on the upper slider 121 and the lower slider 141. The upper threaded section 1511 is threadedly connected to the upper slider 121, and the lower threaded section 1512 is threadedly connected to the lower slider 141. The thread directions of the upper threaded section 1511 and the lower threaded section 1512 are opposite. When the double-headed screw 151 is rotated, the pressing plate 12 and the base 14 move in opposite directions, and the tightness of the spring 22 can be automatically adjusted according to the radius of the cable 9 at the same time.

[0050] It should be noted that anti-slip rubber pads are arranged on the surfaces of the pressing plate 12 and the top plate 13 in contact with the cable 9. A plurality of protruding patterns are arranged on the surface of the anti-slip rubber pad to increase the friction with the cable 9 and prevent the cable 9 from displacing during the operation of the vibration damper.

[0051] Furthermore, the piezoelectric ceramics are arranged at any at least one of the contact surface between the spring 22 and the hanging rod 21, the contact surface between the spring 22 and the ejector rod 131, or the middle internal position of the spring 22.

[0052] Furthermore, the thread pitch of the thread on the upper threaded section 1511 is greater than the thread pitch of the thread on the lower threaded section 1512. When the double-headed screw 151 is rotated, the moving speed of the pressing plate 12 is greater than the moving speed of the base 14. The opening position of the locking groove 11 is arranged at a position slightly above the side surface of the main clamp body 1. Thus, when the pressing plate 12 and the top plate 13 clamp the cable 9, the cable 9 is located at a position lower than the opening of the locking groove 11.

[0053] Furthermore, at least one guide rail 152 passing through the upper slider 121 and the lower slider 141 is also arranged on the clamping device 15.

[0054] Furthermore, the main clamp body 1 and the vertical plate 2 are made of aluminum alloy, the hammer head 4 is made of zinc alloy, and the elastic connecting rod 3 is made of steel cable.

[0055] Further, both ends of the double-headed screw 151 are rotatably connected to the fixed plates, and the two fixed plates are detachably connected to the main clamp body 1 by bolts. At least one end of the double-headed screw 151 is provided with a polygonal hole or a handle for rotating the double-headed screw 151.

[0056] It should be noted that scale marks are provided on the fixed plates of the clamping device 15, and the scale marks correspond to different rotation angles of the double-headed screw 151, so as to intuitively display the current tightness of the spring 22 and facilitate the installer to adjust according to the actual situation of the cable 9.

[0057] Further, a warning light is provided on the main clamp body 1, and the electricity generated each time the piezoelectric ceramic vibrates supplies the warning light to flash once, so that the vibration frequency of the vibration damping hammer can be clearly seen on the ground.

[0058] Further, the electromagnetic device includes an electromagnet and a control circuit. The control circuit controls the magnitude and direction of the energizing current of the electromagnet according to the change in the amount of current detected by the current sensor, so as to accurately adjust the magnitude of the repulsive force or attractive force on the magnetic block 23 and realize stepless adjustment of the elastic force of the spring 22.

[0059] Further, a wear-resistant coating is provided on the surface of the hammer head 4, and the wear-resistant coating is a tungsten carbide coating or a ceramic coating to improve the wear resistance of the hammer head 4 during long-term vibration and extend its service life.

[0060] Further, the vibration damping hammer further includes a remote monitoring module. The remote monitoring module is connected to the power supply of the vibration power generation device and is used to collect the power data generated by the vibration power generation device, the vibration frequency data of the cable 9, etc., and transmit the data to the monitoring center through the wireless communication module so that the staff can understand the working state of the vibration damping hammer in real time.

[0061] Further, an included angle is provided between the hammer head 4 and the elastic connecting rod 3, and the inner side of the hammer head 4 is inclined downward by 10-30 degrees.

[0062] Working principle: The main clamp body 1 clamps the cable 9 through the pressure plate 12 and the top plate 13 in the locking groove 11. When the cable 9 is static, the spring 22 provides an upward elastic force for the top plate 13 to enhance the clamping force on the cable 9. When the cable 9 vibrates, the spring 22 provides a downward elasticity for the vertical plate 2, thereby indirectly enhancing the elastic force of the hammer head 4. At the same time, the hanging rod 21 bounces up and down, squeezing the vibration power generation device, and the piezoelectric ceramics inside generate electric energy and store it in the power rechargeable battery. The charging management circuit has overcharge and over-discharge protection functions to extend the battery life. When the vibration amplitude is too large, the current sensor detects that the current generated by the piezoelectric ceramics exceeds the preset value, and the electromagnetic device is activated. The electromagnetic device includes an electromagnet and a control circuit, which can control the magnitude and direction of the current passing through the electromagnet according to the change of the current amount, and precisely adjust the elastic force of the spring 22 by repelling or attracting the magnetic block 23 to achieve stepless adjustment. When the double-headed screw 151 is rotated, the pressure plate 12 and the base 14 move in opposite directions, and at the same time, the tightness of the spring 22 is automatically adjusted according to the radius of the cable 9.

[0063] In summary, for the energy-saving anti-vibration hammer of this installation, by arranging a pressure plate 12 for clamping the cable 9 downward above the locking groove 11, a top plate 13 for clamping the cable 9 upward below, a hanging rod 21 with its top sliding in the main clamp body 1 above the vertical plate 2, and a top rod 131 with its bottom sliding in the main clamp body 1 at the bottom of the top plate 13, and connecting the end of the hanging rod 21 and the top rod 131 with the spring 22, the dual adjustment of the clamping force on the cable and the elastic force of the hammer head is realized. When the cable 9 is static, the spring 22 provides an upward elastic force for the top plate 13, making the top plate 13 tightly press against the cable 9 and working together with the upper pressure plate 12 to effectively enhance the clamping force on the cable 9 and prevent the anti-vibration hammer from shifting or falling off under static conditions. When the cable 9 vibrates, the spring 22 provides a downward elasticity for the vertical plate 2, and the vertical plate 2 drives the hammer head 4 to move, indirectly increasing the elastic force of the hammer head 4, enabling the hammer head 4 to more powerfully suppress the vibration of the cable 9. At the same time, when the hanging rod 21 bounces up and down, it reciprocally squeezes the vibration power generation device to generate electric energy, realizing the recycling of energy, achieving multiple effects of improving the working stability of the anti-vibration hammer, enhancing the anti-vibration effect, and saving energy.

[0064] The installed energy-saving anti-vibration hammer realizes automatic adjustment of the spring elasticity according to the vibration amplitude by fixedly connecting a magnetic block 23 to a spring 22, arranging a current sensor on the transmission wire between the piezoelectric ceramic and the power supply, and arranging an electromagnetic device in the sliding chute where a hanging rod 21 and a top rod 131 slide. The electromagnetic device is connected to the power supply. When the current sensor detects that the current exceeds a preset value, that is, when it indicates that the vibration amplitude of the cable 9 is too large, the electromagnetic device is activated. By repelling or attracting the magnetic block 23 to slide downward, the elastic coefficient of the spring 22 is changed, thereby increasing the elastic force of the spring 22 on the hanging rod 21. This design can automatically enhance the supporting force of the spring 22 on the vertical plate 2 and the hammer head 4 during severe vibration, enabling the hammer head 4 to more effectively suppress excessive vibration, avoiding damage to the cable 9 due to excessive vibration, achieving the effects of adaptive adjustment, precise anti-vibration, and cable 9 protection, and greatly improving the working performance of the anti-vibration hammer under different vibration conditions.

[0065] The installed energy-saving anti-vibration hammer sets a base 14 at the top of the sliding chute where the hanging rod 21 and the top rod 131 slide. The top of the base 14 supports a top plate 13. A lower slider 141 is fixedly connected to the base 14, and an upper slider 121 is fixedly connected to a pressing plate 12. A clamping device 15 is arranged outside the main clamp body 1. A vertical double-headed screw 151 is arranged on the clamping device 15. The upper half of the double-headed screw 151 is an upper thread section 1511 passing through the upper slider 121, and the lower half is a lower thread section 1512 passing through the lower slider 141. The thread directions of the upper thread section 1511 and the lower thread section 1512 are opposite. This realizes automatic adjustment of the tightness of the spring according to the cable radius. When the double-headed screw 151 is rotated, due to the opposite thread directions of the upper thread section 1511 and the lower thread section 1512, the upper slider 121 and the lower slider 141 will move in opposite directions, thereby driving the pressing plate 12 and the base 14 to move in opposite directions. In this way, the distance between the pressing plate 12 and the top plate 13 in the locking groove 11 can be flexibly adjusted according to cables 9 of different radii, and at the same time, the tightness of the spring 22 can be adjusted accordingly. It achieves the effects of improving the versatility of the anti-vibration hammer, facilitating installation, and optimizing the anti-vibration performance, enabling the anti-vibration hammer to better adapt to cables 9 of various specifications and improving the working efficiency.
