Description

Technical Field

[0001] This utility model belongs to the technical field of tightening devices, and specifically relates to a tightening device for power transmission lines. Background Technology

[0002] The use of tensioning devices for transmission lines is crucial for ensuring the safe, stable, and efficient operation of power transmission systems. If the conductors are too slack, excessive sag can affect the safe distance to the ground or objects below, especially when crossing highways, railways, or other important facilities. If the conductor tension is too high, it may break under extreme weather conditions (such as strong winds or snow) due to the inability to withstand the additional load, causing power outages. Therefore, it is necessary to use tensioning devices to adjust the tension of transmission lines.

[0003] Existing transmission line tightening devices typically tighten the transmission line by installing a tightening component inside a mounting frame and driving the frame to move back and forth. While this method can meet the need for tightening the transmission line, it also means that a lot of dust often adheres to the transmission line, preventing it from being cleaned. The accumulation of dust, salt, or other impurities forms an insulating layer on the conductor surface, increasing the conductor's resistance. As the resistance increases, more electrical energy is converted into heat during transmission, causing unnecessary energy loss and reducing the overall energy transmission efficiency of the power grid. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a tightening device for power transmission lines. It can not only tighten and untighten the power transmission lines, but also clean the power transmission lines with a cleaning brush to effectively remove dust and other impurities, restore the conductors to their optimal conductivity, and collect the impurities in a timely manner through a collection box, thus simplifying the maintenance process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a tightening device for transmission lines, including a fixing plate, a groove is provided at the upper end of the fixing plate, a slider is slidably arranged inside the groove, a mounting frame is provided at the upper end of the slider, a driving component for driving the slider to slide is provided on the fixing plate, a fixing column is provided at the front end of the mounting frame, a cleaning box is provided at the upper end of the fixing column, a cleaning brush is provided inside the cleaning box, a cleaning component is provided at the bottom of the cleaning box, and a tightening component is provided at the rear end of the mounting frame.

[0006] As a further improvement of this utility model, the cleaning component includes a telescopic push rod 1 set on the right side wall of the cleaning box. The telescopic end of the telescopic push rod 1 extends into the interior of the cleaning box and is connected to a cleaning plate. A through hole 1 is opened at the bottom left end of the cleaning box, and a collection box is detachably installed at the lower end of the through hole 1.

[0007] As a further improvement of this utility model, through holes adapted to power transmission lines are provided on both the front and rear side walls of the cleaning box.

[0008] As a further improvement of this utility model, the driving component includes a threaded rod rotatably disposed inside the slide groove, the slider is threadedly connected to the threaded rod, and a servo motor is disposed at the front end of the fixed plate, the output end of the servo motor being connected to the threaded rod via a coupling.

[0009] As a further improvement of this utility model, the tightening component includes a support frame 1 located at the bottom of the rear end of the mounting frame. A rotating wheel 1 is rotatably arranged inside the support frame 1. A telescopic push rod 2 is provided at the upper end of the mounting frame. The output end of the telescopic push rod 2 extends into the interior of the mounting frame and is connected to the support frame 2. A rotating wheel 2 that is adapted to the rotating wheel 1 is rotatably arranged inside the support frame 2.

[0010] As a further improvement of this utility model, anti-slip protrusions are provided on both the first and second rotating wheels.

[0011] As a further improvement of this utility model, motor 2 is provided at the right end of both support frame 1 and support frame 2.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, by setting up a cleaning box, which contains cleaning brushes, dust and other impurities can form an insulating layer on the surface of the wires, increasing resistance and reducing power transmission efficiency. Cleaning the surface of the wires with the cleaning brushes can effectively remove these impurities and restore the wires to their optimal conductivity.

[0014] Secondly, by setting up a collection box, the telescopic end of the telescopic push rod pushes the cleaning plate to move, thereby pushing the dust and other impurities cleaned by the cleaning brush to the left end of the cleaning box, and falling into the collection box through the through hole, making it convenient to clean and collect the dust in a timely manner.

[0015] Thirdly, both the first and second rotating wheels are equipped with anti-slip protrusions. These protrusions increase the contact area and friction coefficient between the wheel surface and the wire, effectively preventing the wire from slipping during tightening or loosening, thus ensuring the accuracy of the operation.

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 2 As shown in Figure 3, a tightening device for a power transmission line includes a fixing plate 101. A groove is provided at the upper end of the fixing plate 101, and a slider is slidably disposed inside the groove. A mounting bracket 103 is provided at the upper end of the slider. A driving component for driving the slider to slide is provided on the fixing plate 101. A fixing post 104 is provided at the front end of the mounting bracket 103. A cleaning box 105 is provided at the upper end of the fixing post 104. A cleaning brush 106 is provided inside the cleaning box 105. Dust and other impurities will form an insulating layer on the surface of the conductor, increasing resistance and causing a decrease in power transmission efficiency. By cleaning the surface of the conductor with the cleaning brush 106, these impurities can be effectively removed, restoring the conductor to its optimal conductivity. A cleaning component is provided at the bottom of the cleaning box 105, and a tightening component is provided at the rear end of the mounting bracket 103.

[0024] like Figure 2 , 3As shown, the cleaning component includes a telescopic push rod 201 mounted on the right side wall of the cleaning box 105. The telescopic end of the telescopic push rod 201 extends into the interior of the cleaning box 105 and is connected to a cleaning plate 202. A through hole 204 is provided at the bottom left end of the cleaning box 105. A collection box 203 is detachably mounted at the lower end of the through hole 204. When the telescopic push rod 201 is activated, the telescopic end of the push rod pushes the cleaning plate 202 to move, thereby pushing the dust and other impurities cleaned by the cleaning brush 106 to the left end of the cleaning box 105 and falling into the collection box 203 along the through hole 204, facilitating timely cleaning and collection of the dust.

[0025] like Figure 2 , 3 As shown, the front and rear side walls of the cleaning box 105 are provided with through holes 205 that are compatible with the power transmission lines.

[0026] like Figure 1 As shown, the driving component includes a threaded rod 301 rotatably disposed inside the slide groove. The slider is threadedly connected to the threaded rod 301. A servo motor 302 is disposed at the front end of the fixed plate 101. The output end of the servo motor 302 is connected to the threaded rod 301 through a coupling. When the servo motor 302 is started, the threaded rod 301 can be rotated. The rotation of the threaded rod 301 drives the slider to move along the slide groove, thereby causing the slider to drive the mounting bracket 103 to move back and forth through the fixed column 104. In turn, the power transmission line can be tightened or loosened by the tightening component.

[0027] like Figure 1 , 2 As shown in Figure 4, the tightening component includes a support frame 303 located at the bottom rear end of the mounting frame 103. A rotating wheel 304 is rotatably mounted inside the support frame 303. A telescopic push rod 305 is located at the upper end of the mounting frame 103. The output end of the telescopic push rod 305 extends into the mounting frame 103 and connects to a support frame 306. A rotating wheel 307, which is adapted to the rotating wheel 304, is rotatably mounted inside the support frame 306. When the telescopic push rod 305 is activated, the telescopic end of the telescopic push rod 305 drives the support frame 306 to move downward. The support frame 306 drives the rotating wheel 307 to move downward, thereby slightly squeezing the transmission line to prevent it from moving. Then, the tightening component moves backward to tighten the transmission line.

[0028] like Figure 1 , 2 As shown in Figure 4, motor 2 309 is installed at the right end of both support frame 1 303 and support frame 2 306.

[0029] In use, the two ends of the power transmission line are passed through the through holes 205 at both ends of the cleaning box 105. The motors 309 on the support frame 303 and 306 are then turned on. The motors 309 drive the rotating wheels 304 and 307 to rotate through their output ends, allowing the power transmission line to be laid. During the laying process, dust and other impurities will adhere to the power transmission line. Dust and other impurities will form an insulating layer on the surface of the conductor, increasing resistance and reducing power transmission efficiency. The cleaning brush 106 can effectively remove these impurities and restore the conductor to its optimal conductivity. Then, the telescopic push rod 201 is activated. The telescopic end of the push rod pushes the cleaning plate 202 to move, which in turn pushes the dust and other impurities cleaned by the cleaning brush 106 to the left end of the cleaning box 105. They then fall into the collection box 203 through the through hole 204, facilitating timely cleaning and collection of the dust.

[0030] When it is necessary to tighten the transmission line, the telescopic push rod 305 is activated. The telescopic end of the telescopic push rod 305 drives the support frame 306 to move downward. The support frame 306 drives the rotating wheel 307 to move downward, thereby slightly compressing the transmission line to prevent it from moving. Then, the servo motor 302 is activated, which makes the threaded rod 301 rotate. The rotation of the threaded rod 301 drives the slider to move backward along the slide groove, thereby causing the slider to drive the mounting frame 103 to move backward through the fixed column 104, thereby tightening the transmission line.

[0031] According to another embodiment of the present invention, such as Figure 1 , 2 As shown in Figure 4, both the first rotating wheel 304 and the second rotating wheel 307 are provided with anti-slip protrusions 308. The anti-slip protrusions 308 increase the contact area and friction coefficient between the rotating wheel surface and the wire, effectively preventing the wire from slipping during tightening or loosening, and ensuring the accuracy of operation.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
