Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of fluid pressure actuators, and in particular to a liquid damping shock absorber for transmission lines. Background Art

[0002] With the acceleration of the global industrialization and urbanization processes, the demand for energy continues to grow. As one of the core energies in modern society, the stability and reliability of power supply are directly related to the sustainable development of the economy and the normal operation of society. In recent years, extreme weather events have occurred frequently, such as strong winds, heavy rains, ice disasters, etc., posing severe challenges to the safe operation of power infrastructure. At the same time, with the rise of smart grids and energy Internet, the requirements for the intelligence, efficiency, and safety of transmission lines are getting higher and higher. Therefore, developing efficient and reliable anti-vibration technologies for transmission lines has become an important topic for ensuring the stable operation of the power system.

[0003] Under the trend of increasing transmission line lengths and diverse complex terrains, the vibration problem of transmission lines in natural disasters has become increasingly prominent. Multiple factors such as wind force, ice coating, and mechanical vibration can cause transmission line oscillations, leading to fatigue damage, fracture, or even collapse of the transmission lines, posing a serious threat to the safe operation of the power system. Modern society highly relies on power supply, and any power outage event caused by transmission line failures may cause huge losses to economic activities. Therefore, ensuring the safe operation of transmission lines and reducing failures caused by vibration are important measures for maintaining social and economic stability.

[0004] Traditional transmission line shock absorbers, such as vibration dampers, detuned pendulums, phase spacers, etc., although can suppress the galloping of transmission lines to a certain extent, most of these devices are developed for specific excitation mechanisms, and their anti-galloping and shock-absorbing effects have limitations. For example, the vibration damper has poor effect in low-frequency galloping, and the phase spacer cannot fully exert its anti-galloping potential under complex working conditions such as strong winds or ice coating.

However, it is obvious to those skilled in the art that the technical solutions provided by the present utility model can be implemented without one or more of these details.

[0048] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present utility model. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form.

[0049] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present utility model is thorough and complete, and the concept of these exemplary embodiments is fully communicated to those of ordinary skill in the art.

[0050] Such as Figures 1 to 6As shown in the figure, an embodiment of the present utility model provides a liquid damping shock absorber for a transmission line, which includes: a main chamber 110, a receiving space is formed in the main chamber 110 for storing damping liquid; a liquid supplement chamber 120, the liquid supplement chamber 120 is located below the main chamber 110 and is connected to the main chamber 110 through an inlet pipe and an outlet pipe; a fixing component 130, the fixing component 130 is arranged on both sides of the main chamber 110, and the fixing component 130 includes a plurality of connecting pieces 131, and the fixing component 130 is used to connect two adjacent cables.

[0051] The liquid damping shock absorber for a transmission line provided by the embodiment of the present utility model includes a main chamber 110, a liquid supplement chamber 120 and a fixing component 130. Based on this, during the use of the liquid damping shock absorber for a transmission line, the liquid damping shock absorber for a transmission line can be connected between two adjacent cables through the fixing component 130. When the cables dance due to external environmental reasons, the damping liquid in the main chamber 110 is subjected to vibration excitation, generating flow and stirring, thereby generating a damping force. This damping force is opposite to the vibration direction of the cable, and can effectively absorb and dissipate vibration energy, reducing the dancing amplitude of the transmission line. At the same time, through the setting of the liquid supplement chamber 120, the amount of damping liquid in the main chamber 110 can be changed based on external environmental factors, thereby adjusting the shock absorption capacity of the main chamber 110, enabling the liquid damping shock absorber for a transmission line to be applicable to different wind force levels and weather environments, increasing the application range of the liquid damping shock absorber. Further, the liquid supplement chamber 120 is arranged below the main chamber 110, and the liquid supplement chamber 120 can also act as a hammer body, and can also play a role in suppressing the dancing of the cable, and can better control the dancing range of the cable.

[0052] It can be understood that the volume of the main chamber 110 is larger than the volume of the liquid supplement chamber 120, and the liquid supplement chamber 120 is also used to store damping liquid to facilitate the replenishment of damping liquid to the main chamber 110. Through the setting of the inlet pipe and the outlet pipe, in addition to replenishing damping liquid into the main chamber 110, the damping liquid in the main chamber 110 can also be transported to the liquid supplement chamber 120 through the outlet pipe, so that the liquid damping shock absorber for a transmission line can be applicable to different vibration frequencies of the cable, and can achieve a better suppression effect on dancing.

[0053] The liquid damping shock absorber for transmission lines provided by the embodiments of the present utility model adopts the liquid damping technology, utilizes the viscosity and inertia of the liquid to dissipate the vibration energy of the transmission line, thereby significantly reducing the dancing amplitude of the transmission line. The device can adjust the damping parameters according to the vibration conditions of the transmission line, realize intelligent adjustment, and adapt to complex and changeable working conditions. At the same time, the structural design of the device is optimized to make it more concise and light, facilitate installation and maintenance, and reduce the safety risks of high-altitude operations. In addition, the device is applicable to various complex working conditions and long-span transmission lines, effectively solves the problem that the energy consumption effect of traditional damping devices is not obvious in long-span lines, and improves the safety and stability of transmission lines.

[0054] In some examples, in order to ensure that the main chamber 110 of the liquid damping shock absorber for transmission lines should be made of high-strength materials with good impact resistance and corrosion resistance. At the same time, the liquid chamber and the damping piston inside the shock absorber body are precisely processed to ensure their stability and reliability during long-term operation.

During use, the main chamber 110 can be located in the middle of multiple cables, and can achieve a better shock absorption effect.

[0059] As Figures 5 to 6 shown, in a feasible implementation, the connecting member 131 includes: a support rod 1311, and the support rod 1311 is rotatably connected to the fixed bracket 132 through a first connecting rod 133; a fastener 1312, the fastener 1312 is arranged at one end of the support rod 1311 away from the fixed bracket 132, and the fastener 1312 is used for fastening on the cable.

By arranging the support rod 1311, a certain distance can be provided between the fastener 1312 and the fixed bracket 132 to ensure that the fastener 1312 can be connected to the cable. By arranging the fastener 1312, it is convenient for the liquid damping shock absorber to establish a connection relationship with the cable.

[0061] As Figures 5 to 6 shown, in a feasible implementation, the fastener 1312 includes: a fixed part 13121, the fixed part 13121 is fixedly connected to the support rod 1311 or is an integral structure with the support rod 1311; a movable part 13122, the movable part 13122 is rotatably connected to the support rod 1311 through a second connecting rod 134, and a clamping space is formed between the fixed part 13121 and the movable part 13122.

[0062] In this technical solution, the structural composition of the fastener 1312 is further provided. The fastener 1312 may include a fixed part 13121 and a movable part 13122. During use, the movable part 13122 can rotate relative to the support rod 1311 through the second connecting rod 134 to open the clamping space, and then the fastener 1312 can be hung on the cable. After that, closing the movable part 13122 can complete the connection between the fixing component 130 and the cable, which is convenient for fixing the fixing component 130, especially for connecting the fixing component 130 to a cable with a certain bend, replacing the bolt fixing method in the traditional technology, and facilitating the connection between the liquid damping shock absorber and the cable.

[0063] As Figures 5 to 6 shown, in a feasible implementation, the outer edge contour of the fixed bracket 132 is quadrilateral, and there are four connecting members 131, which are arranged at the corners of the fixed bracket 132.

[0064] In this technical solution, the style of the fixing bracket 132 is further provided. The fixing bracket 132 can be quadrilateral, and there are four connecting members 131 arranged at the corners of the fixing bracket 132. Based on this, the four connecting members 131 are arranged at the corners of the fixing bracket 132. The four connecting members 131 can be connected to four cables, and the main chamber 110 can be arranged in the middle of the four cables, which can achieve a better anti-galloping effect.

[0065] In a feasible implementation manner, the liquid damping shock-absorbing device for a transmission line further includes: a partition plate, which is arranged in the main chamber 110 and is used to divide the accommodating space into multiple shock-absorbing spaces; a damping piston, which is connected to the main chamber 110 and is arranged in the shock-absorbing space.

[0066] In this technical solution, the specific style of the main chamber 110 is further provided. A partition plate can be arranged within the main chamber 110. Through the partition plate, the main chamber 110 can be divided into multiple shock-absorbing spaces, and then a damping piston is arranged within the shock-absorbing spaces, which can further improve the shock-absorbing effect of the main chamber 110.

[0067] In a feasible implementation manner, the liquid damping shock-absorbing device for a transmission line further includes: a vibration sensor, which is arranged on the main chamber 110; a proximal controller, which is arranged on the main chamber 110 and is connected to the vibration sensor, and is used to control the replenishing chamber 120 to replenish damping liquid to the main chamber 110 or convey damping liquid from the main chamber 110 to the replenishing chamber 120 based on the detection result of the vibration sensor.

[0068] In this technical solution, the liquid damping shock-absorbing device for a transmission line further includes a vibration sensor and a proximal controller. Based on this, the vibration condition of the cable can be detected through the vibration sensor, and then the proximal controller can control the replenishing chamber 120 to replenish damping liquid to the main chamber 110 or convey damping liquid from the main chamber 110 to the replenishing chamber 120 based on the detection result of the vibration sensor. Based on the setting of the vibration sensor and the proximal controller, the total amount of damping liquid in the main chamber 110 can be dynamically adjusted, so that the liquid damping shock-absorbing device for a transmission line can adapt to different galloping conditions of the cable and can achieve a better anti-galloping effect.

[0069] In some examples, the replenishing chamber 120 can also be manually controlled to replenish damping liquid into the main chamber 110. For example, a person can control the opening or closing of the liquid inlet pump 140 and the liquid outlet pump 150 based on the wind force level of the environment where the cable is located, and then adjust the amount of damping liquid in the main chamber 110. Similarly, galloping can be better suppressed.

[0071] In this technical solution, the liquid damping shock absorber for the power transmission line may further include a host computer, which is connected to the vibration sensor and the proximal controller. The host computer obtains the detection result of the vibration sensor and determines whether to supplement the damping liquid into the main chamber 110 or output the damping liquid to the liquid supply chamber 120 via the main control chamber based on the detection result of the vibration sensor. Then, the host computer sends a control signal to the proximal controller, and the specific action of the liquid supply chamber 120 can be controlled. By setting the host computer in this way, the operation work can be arranged in the host computer, which is beneficial to the miniaturization of the proximal controller, making the liquid damping shock absorber for the power transmission line more energy-saving and facilitating the remote control of the liquid damping shock absorber for the power transmission line.
