Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage line fault detection equipment, in particular to a high-voltage transmission line positioning device. Background Art

[0002] High-voltage transmission line locating devices, also known as high-voltage transmission line fault locators, are used to monitor the status of transmission lines in real time and accurately locate the fault point when a fault occurs. When locating high-voltage transmission line faults in the field, due to the harsh environment, the fault locator is typically placed elevated to prevent moisture and dirt from contaminating it.

[0003] However, the legs of the existing placement rack are fixed on the placement box and cannot be folded and stored, which is extremely inconvenient to use. In addition, the height of the placement rack cannot be adjusted, and the legs of the placement rack cannot be directly inserted into the field operation site for fixation, which brings great inconvenience to the installation and use of the line fault detector. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a high-voltage transmission line positioning device to solve the technical problems in the prior art that the placement rack cannot be folded and stored, the height cannot be adjusted, and the device cannot be directly inserted into a field operation site for fixation.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-voltage transmission line positioning device, comprising a support, a bracket provided at the lower end of the support, an instrument box provided at the upper end of the support, a line fault locator placed in the instrument box, the support comprising three legs, the legs comprising a sleeve and a foot, one end of the sleeve being movably connected to the support, an internal threaded hole being provided on the inner wall of the other end of the sleeve, an external thread matching the internal thread being provided at one end of the foot, the foot being screwed into the sleeve, an adjusting nut being fixed on the foot, the other end of the foot being processed into a conical structure, and a pedal being provided on the end of the foot close to the conical structure.

[0006] Furthermore, the support includes an adapter plate, a support column is installed on the adapter plate, a support plate is installed at one end of the support column, and the support plate is detachably connected to the instrument box by a first bolt.

[0007] Furthermore, three hinge seats are evenly distributed on the outer wall of the adapter plate.

[0008] Furthermore, the hinge seat and the sleeve are rotatably connected via a hinge shaft.

[0009] Furthermore, a non-slip and wear-resistant layer is provided on a side of the pedal away from the conical structure.

[0021] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0022] like Figure 1-2 As shown, a high-voltage transmission line positioning device includes a support 1, a bracket 2 is provided at the lower end of the support 1, an instrument box 3 is provided at the upper end of the support 1, and a line fault locator 4 is placed in the instrument box 3. The support 2 includes three legs 21, each of which includes a sleeve 211 and a foot 212. One end of the sleeve 211 is rotatably connected to the support 1 to facilitate the folding and storage of the support 2. When in use, one of the legs 21 is supported on the ground, and then the other two legs 21 are held by both hands to open them to a suitable angle. After use, the legs 21 can be folded and stored by holding them. Please refer to Figure 2 The other end of the sleeve 211 has an internally threaded hole formed in its inner wall. One end of the leg 212 is provided with an external thread that mates with the internal thread. The leg 212 is threaded into the sleeve 211. An adjusting nut 213 is also fixed to the leg 212. By turning the adjusting nut 213, the threaded length of the leg 212 in the sleeve 211 can be adjusted, allowing the leg 21 to be extended or retracted to the desired length, thereby positioning the bracket 2 at an appropriate height to meet the monitoring height of the line fault locator 4. Furthermore, the threaded assembly prevents relative displacement between the leg 212 and the sleeve 211, ensuring the stability of the bracket 2 and improving the monitoring accuracy of the line fault locator 4. The other end of the leg 212 is machined into a tapered structure. A pedal 214 is provided on the end of the leg 212 near the tapered structure. By stepping on the pedal 214, the leg 212 is inserted into the soil, allowing the bracket 2 to be directly fixed to the field work site, greatly facilitating the installation and use of the line fault locator 4.

[0023] As a further improvement, see Figure 1 and Figure 2 The support 1 includes an adapter plate 11, on which a support column 13 is mounted. A support plate 12 is mounted at one end of the support column 13. The support plate 12 is detachably connected to the instrument box 3 via a first bolt 5. When in use, after installing the support 1, align the bolt holes at the bottom of the instrument box 3 with the bolt holes on the support plate 12, and tighten the first bolt 5 to fasten the instrument box 3 to the support plate 12. After monitoring is completed, loosen the first bolt 5 to disassemble and store the instrument box 3. A protective shell 7 is also provided on the inner wall of the instrument box 3 to protect the line fault locator 4. Please refer to Figure 2Three hinge seats are evenly distributed on the periphery of the adapter plate 11, and the hinge seats are rotatably connected to one end of the sleeve 211 through the hinge shaft 6.

[0024] As a further improvement, see Figure 3 A non-slip and wear-resistant layer is also provided on the side of the pedal 214 away from the conical structure of the support leg 212, which is used to increase the friction between the pedal 214 and the sole of the foot, increase the speed at which the support leg 212 is inserted into the soil layer, and thereby improve the installation efficiency of the line fault locator 4.
