AI Technical Summary
The existing anti-vibration hammers are prone to freezing when the temperature is low in rainy and snowy weather, resulting in the failure of the anti-vibration function and may be frozen with the wire, losing the anti-vibration and vibration absorption function.
An automatic temperature-controlled anti-icing and vibration-proof hammer is designed, using a wire clamp body and a wire clamp cover plate, with built-in heating resistors and temperature-controlled resistors. The temperature is detected by the temperature-controlled resistance. When it is lower than the set temperature, the energy storage battery pack supplies power to the heating resistors to keep the temperature of the anti-vibration hammer exceeding the set temperature and preventing icing.
Ensure that the anti-vibration hammer is always effective under low temperature conditions, prevents freezing with the wires, maintains anti-vibration function, and ensures the stable operation of overhead lines.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibration damping hammers, in particular to an automatic temperature control ice-proof and vibration damping hammer. Background Technique
[0002] The vibration damping hammer is provided to reduce the vibration of the wire caused by the wind. The high-voltage overhead line poles are at a relatively high position and the span is relatively large. When the wire is affected by the wind, vibration will occur. When the wire vibrates, the working conditions at the wire suspension are the most unfavorable. Due to multiple vibrations, the wire will undergo fatigue failure due to periodic bending. When the span of the overhead line is greater than 120 meters, a vibration damping hammer is generally used for vibration prevention.
[0003] For the existing vibration damping hammer, when the temperature is relatively low in rainy and snowy weather, ice is likely to form around the vibration damping hammer, which cannot ensure that the vibration damping hammer is always in a working state, and it is easy to freeze into a whole with the wire, thus losing the function of vibration prevention and absorption. Content of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a vibration damping hammer with automatic temperature control and ice prevention is proposed.
[0005] The utility model adopts the following technical scheme: an automatic temperature control ice-proof and vibration damping hammer, including a wire clamp body and a wire clamp cover plate. The wire clamp body and the wire clamp cover plate are used for installing a wire. A steel strand is penetrated through the bottom end of the wire clamp body. Hammer heads are penetrated through both ends of the steel strand. A heating resistor is arranged on the steel strand between the wire clamp body and the hammer head.
[0006] In the middle of the inner wall of the hammer head, an energy storage battery pack is arranged, and a spring is arranged on the outer wall of the energy storage battery pack. One end of the spring is connected with a piezoelectric ceramic sheet. A temperature control resistor is arranged on the outer side wall of one end of the hammer head; the temperature control resistor is connected to a control unit, the control unit is connected to the energy storage battery pack, and the energy storage battery pack is connected to the heating resistor.
[0007] As a further description of the above technical scheme: a fixed sleeve is arranged on one side of the inner wall of the hammer head, and the steel strand is fixedly installed with the fixed sleeve.
[0008] As a further description of the above technical scheme: bolt through holes are formed in the inner wall of the wire clamp body, and water leakage grooves are formed at the bottom ends of the bolt through holes.
[0009] As a further description of the above technical scheme: the heating resistor is a thermal resistance spring.
[0010] As a further description of the above technical scheme: the surface of the piezoelectric ceramic sheet is attached to both sides of the inner wall of the hammer head.
[0011] As a further description of the above technical solution: the energy storage battery pack is annular.
[0012] In the operation of the present utility model, through the temperature control resistor, when the detected air temperature is lower than the set temperature, the energy storage battery pack in the middle of the hammer head acts to supply power to the heating resistor, and through the heat, the temperature of the anti-vibration hammer is ensured to exceed the set temperature, ensuring that ice does not form around the anti-vibration hammer, ensuring that the anti-vibration hammer always works, and preventing it from freezing into a whole with the wire and thus losing the anti-vibration and vibration absorption functions.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Referring to Figures 1-4 , an automatic temperature control anti-icing and anti-vibration hammer provided by the present utility model includes a clamp body 1 and a clamp cover plate 5. The clamp body 1 and the clamp cover plate 5 are used to install a wire. A steel strand 4 penetrates through the bottom end of the clamp body 1, and both ends of the steel strand 4 penetrate through a hammer head 7. A heating resistor 6 is provided on the steel strand 4 between the clamp body 1 and the hammer head 7.
[0021] In the middle of the inner wall of the hammer head 7, there is an energy storage battery pack 9, and on the outer wall of the energy storage battery pack 9, there is a spring 10. One end of the spring 10 is connected to a piezoelectric ceramic sheet 11, and on the outer side wall of one end of the hammer head 7, there is a temperature control resistor 12; the temperature control resistor 12 is connected to a control unit, the control unit is connected to the energy storage battery pack 9, and the energy storage battery pack 9 is connected to a heating resistor 6.
[0022] The temperature is collected by the temperature control resistor, transmitted to the control unit, and compared with the temperature threshold to obtain a start or stop instruction.
[0023] The control unit is used to process the collected data for subsequent control. The control unit is a conventional device. In the application, the control unit is placed inside the hammer head 7.
[0024] On one side of the inner wall of the hammer head 7, there is a fixed sleeve 8, and the steel strand 4 is fixedly installed with the fixed sleeve 8. In this way, the connection reliability is improved.
[0025] In the inner wall of the wire clamp body 1, there are bolt through holes 2, and at the bottom end of the bolt through holes 2, there are water leakage grooves 3 to avoid water accumulation.
[0026] The heating resistor 6 is a thermal resistance spring. In this way, it is convenient for sleeving and the installation is reliable.
[0027] The spring 10 is spiral. There are multiple groups of springs 10, and the spring 10 is made of brass components. The surface of the piezoelectric ceramic sheet 11 is attached to both sides of the inner wall of the hammer head 7.
[0028] The energy storage battery pack 9 is annular. In this way, it is convenient for the steel strand 4 to pass through; at the same time, several springs 10 can be arranged on the annular surface.
[0029] Working principle: Through the temperature control resistor 12, when the detected air temperature is lower than 5 degrees, the energy storage battery pack 9 in the middle of the hammer head 7 acts to supply power to the heating resistor 6. Through heat transfer, it is ensured that the temperature of the vibration damping hammer exceeds 5 degrees, ensuring that ice does not form around the vibration damping hammer, ensuring that the vibration damping hammer always works and will not freeze into a whole with the wire, thus losing the function of vibration damping and vibration absorption.
[0030] When the hammer head 7 is running normally, the hammer head 7 will generate slight vibrations to absorb the vibration energy of the wire through the steel strand 4. The hammering of the hammer head 7 will drive the energy storage battery pack 9 installed inside the hammer head 7 to move in different directions. The energy storage battery pack 9 will transfer the gravitational energy to the piezoelectric ceramic sheet 11 on the surface through the spring 10, causing the piezoelectric ceramic sheet 11 to be squeezed to generate electric energy, and then the electric energy will be transferred to the energy storage battery pack 9 for storage. Since the vibration damping hammer is working, the hammer head 7 of the vibration damping hammer will move together, causing the piezoelectric energy storage inside the hammer head 7 to always work to ensure that the line always generates electric energy.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
