Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] This utility model provides a dynamic sensing and monitoring device for power transmission lines. It clamps the cable using an elastic clamping method, enabling rapid cable clamping and monitoring, thus ensuring work efficiency. Please refer to [link / reference needed]. Figure 1 , Figure 4 and Figure 6 It includes a base 100, a spring buckle 200, a fixing mechanism 300, a cable 400, a drive mechanism 500, and a locking device 600;

[0046] Example 1

[0047] Please see Figure 1 The spring clip 200 is detachably mounted on the top of the base 100;

[0048] The fixing mechanism 300 is rotatably mounted on the top of the base 100 via the spring buckle 200, and the spring buckle 200 is connected to the fixing mechanism 300;

[0049] The fixing mechanism 300 is secured by the spring buckle 200, which covers the cable 400 to fix it. When disassembly is required, the fixing mechanism 300 is manually moved to overcome the elasticity of the spring buckle 200, so that the fixing mechanism 300 is away from the cable 400, and the base 100 can be removed from the cable. The cable is clamped by the elastic clamp, which can quickly clamp the cable and monitor the cable, ensuring work efficiency.

[0050] Example 2

[0051] Please see Figure 1-3 The inner cavity of the base 100 can be detachably equipped with a high-precision inertial measurement unit (IMU), a high-sensitivity accelerometer, a tilt sensor, a three-dimensional attitude sensor, and a high-precision contact temperature sensor.

[0052] The high-precision inertial measurement unit (IMU) can acquire three-dimensional motion data of the conductor in real time and accurately measure the amplitude, frequency and trajectory of the galloping. It has a galloping early warning function and automatically alarms when the galloping amplitude exceeds the set threshold.

[0053] High-sensitivity accelerometers monitor the frequency and amplitude of aerodynamic vibrations and subspan oscillations to assess the impact of vibrations on conductor fatigue life;

[0054] Real-time calculation of conductor sag changes based on tilt sensors and temperature compensation algorithms, combined with meteorological data to predict sag development trends;

[0055] Three-dimensional attitude sensors accurately measure conductor offset angles and combine wind speed and direction data to assess wind deviation risk, providing a basis for line design and modification.

[0056] High-precision contact temperature sensors monitor the operating temperature of conductors in real time and combine this with current data to assess the current carrying capacity of the line, in conjunction with specialized auxiliary installation tools;

[0057] There are two spring clips 200, and each spring clip 200 includes a mounting shaft 210 and a coil spring 220.

[0058] Mounting shaft 210 is longitudinally mounted at both ends of the top of base 100;

[0059] The coil spring 220 is sleeved on the outer circumferential wall of the mounting shaft 210 and is movably connected to the mounting shaft 210;

[0060] The end of the coil spring 220 is integrally formed with a fixed end 221, which is inserted into the side wall of the base 100.

[0061] The other end of the coil spring 220 is integrally formed with a connecting end 222, and the end of the connecting end 222 is integrally formed with a working end 223. The working end 223 is located on the top of the base 100 but does not contact the base 100.

[0062] There are two fixing mechanisms 300, each including a top plate 310, a side plate 320, and a pressure plate 330.

[0063] The top plate 310 covers the top of the base 100 and is positioned at the lower end of the working end 223;

[0064] There are two side panels 320, which are integrally formed on the bottom front and rear sides of the top plate 310, one in front and one in back. The side walls of the side panels 320 are provided with connecting holes 321.

[0065] The connecting hole 321 matches the mounting shaft 210. The side plate 320 is sleeved on both ends of the outer circumferential wall of the mounting shaft 210 through the connecting hole 321, and is set on the inner side of the coil spring 220 and contacts the end of the coil spring 220.

[0066] The pressure plate 330 is integrally formed and extends obliquely upward at the end of the top plate 310, and is disposed at the lower end of the working end 223 in contact with the working end 223.

[0067] The working end 223 is driven by the elastic force of the coil spring 220 to generate a downward force. The downward force of the working end 223 causes the pressure plate 330 to flip downward around the mounting shaft 210 and press down on the cable 400, fixing the cable 400 between the pressure plate 330 and the base 100. When disassembly is required, the pressure plate 330 can be manually moved to overcome the elastic force of the coil spring 220. Under manual drive, the pressure plate 330 flips upward around the mounting shaft 210 and detaches from the cable 400, allowing the base 100 to be removed from the cable 400. The cable is clamped by the elastic clamping method, which can quickly clamp and monitor the cable, ensuring work efficiency.

[0068] Example 3

[0069] Please see Figure 1-5 To ensure clamping force, the spring 220 generally has a high tension, and manually turning the pressure plate 330 requires a large force, resulting in high labor intensity. Therefore, in order to reduce the labor intensity of the workers, this equipment is also equipped with a drive mechanism 500, which saves force and reduces the labor intensity of the workers.

[0070] The mounting shaft 210 is detachably connected to the side plate 320 via a spline or a key;

[0071] The drive mechanism 500 includes a first gear 510, a drive shaft 520, and a second gear 530;

[0072] The first gear 510 is detachably mounted on the outer circumferential wall of the mounting shaft 210 via a spline or a flat key and is located at the bottom of the top plate 310 but does not contact the top plate 310.

[0073] The drive shaft 520 is movably mounted on the end of the base 100 via a bearing and is positioned at the lower end of the mounting shaft 210 and parallel to the mounting shaft 210.

[0074] The end of the drive shaft 520 is provided with a connecting groove 521, which is an internal hexagonal groove. The drive shaft 520 can be rotated by using an electric drill to hold an internal hexagonal wrench. The selection can be made according to the work needs.

[0075] The second gear 530 is detachably mounted on the outer circumferential wall of the drive shaft 520 via a spline or flat key and is located at the lower end of the first gear 510 to mesh with the first gear 510.

[0076] The drive shaft 520 drives the second gear 530 to rotate, which in turn drives the first gear 510 to rotate. The first gear 510 then drives the mounting shaft 210 to rotate, which in turn drives the side plate 320 to rotate. The side plate 320 then drives the pressure plate 330 to flip upwards. The upward flipping of the pressure plate 330 overcomes the elasticity of the coil spring 220 and releases the cable 400 from its fixation. The rotational force generated by the electric drill is used to flip the pressure plate 330, eliminating the need for manual operation and effectively reducing the labor intensity of the workers.

[0077] Example 4

[0078] Please see Figure 1-8 The coil spring 220 has a limited service life. Repeatedly flipping the pressure plate 330 will cause the spring force of the coil spring 220 to decrease, thereby affecting the clamping force. The base 100 is at risk of falling off the cable. Therefore, in order to ensure the clamping force of the pressure plate 330 and ensure the safety of the equipment, this device is also equipped with a locking device 600.

[0079] Electromagnets 110 are embedded in the four corners of the top of the base 100, such as... Figure 7 As shown, the top plane of the electromagnet 110 is flush with the top plane of the base 100, and the contact part between the electromagnet 110 and the base 100 is treated to prevent electromagnetic interference.

[0080] The inner cavity of the base 100 is also equipped with a current transformer power supply device, which is connected to a cable to draw power from the cable to supply power to the electromagnet 110.

[0081] The locking device 600 includes a connecting plate 610, a mounting plate 620, and a magnetic metal sheet 630;

[0082] The connecting plate 610 is fixed to the bottom of the outer side wall of the side plate 320 by bolts or welding;

[0083] The mounting plate 620 is welded to the connecting plate 610 at one end away from the side plate 320, which corresponds to the electromagnet 110.

[0084] The magnetic metal sheet 630 is detachably mounted on the mounting plate 620 by bolts on the side away from the connecting plate 610 and in contact with the electromagnet 110.

[0085] When the pressure plate 330 is in the closed state to clamp and fix the cable 400, the magnetic metal sheet 630 comes into contact with the electromagnet 110. The electromagnet 110 is energized and generates magnetism, attracting the magnetic metal sheet 630. The side plate 320 is fixed by electromagnetic attraction, thereby fixing and restricting the movement of the pressure plate 330. Even after the coil spring 220 fails, the cable 400 can still be clamped and fixed, preventing the base 100 from falling off and ensuring the safety of the equipment. When the cable 400 is released, the power supply to the electromagnet 110 is disconnected. The electromagnet 110 is de-energized and loses its magnetism, releasing the attraction of the magnetic metal sheet 630, thereby releasing the restriction on the pressure plate 330. The pressure plate 330 is flipped over to release the fixation on the cable 400, and the base 100 is removed from the cable 400.

[0086] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
