Description

Technical Field

[0001] The invention relates to the technical field of electric power instrument installation tools, and in particular to an installation tool for a fault indicator. Background Art

[0002] Most 10kV overhead lines are erected outdoors in a harsh operating environment, with a high rate of failures caused by external forces such as lightning, strong winds, and heavy rain. When a single-phase grounding fault occurs in an overhead line, it is difficult to locate the fault section, which endangers the safety of people and animals and greatly reduces the reliability of regional power supply.

[0003] To solve this problem, fault indicators are usually installed on overhead lines. Once a fault occurs in the line, the fault indicator will flash different indicator lights to indicate the type of fault. Because fault indicators are installed manually, installers need to step on a ladder to get close to the line, open the upper shell of the fault indicator, place the line between the upper shell and the lower shell, and then snap the upper shell and the lower shell together. The installation process requires the installer to operate with both hands, which can easily cause danger of falling from the ladder, and the installation efficiency is low.

[0004] In view of the above problems, it is necessary to develop an installation tool for a fault indicator to solve the above problems. Summary of the invention

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0036] Most 10kV overhead lines are erected outdoors in a harsh operating environment, with a high rate of failures caused by external forces such as lightning, strong winds, and heavy rain. When a single-phase grounding fault occurs in an overhead line, it is difficult to locate the fault section, which endangers the safety of people and animals and greatly reduces the reliability of regional power supply.

[0037] To solve this problem, a fault indicator 100 is usually installed on an overhead line. Once a line fault occurs, the fault indicator 100 will flash different indicator lights to indicate the type of fault. Figure 1 As shown, the fault indicator 100 includes an upper shell 101 and a lower shell 102 which are rotatably connected, and the upper shell 101 can be buckled with the lower shell 102. A torsion spring is arranged between the upper shell 101 and the lower shell 102, and the torsion spring can drive the upper shell 101 to rotate in the direction of buckling with the lower shell 102. When the upper shell 101 and the lower shell 102 are buckled, there is a through hole 103 between the upper shell 101 and the lower shell 102 for the circuit to pass through. However, different circuits have different diameters. In order to improve the applicability of the fault indicator 100, the lower shell 102 is rotatably connected to two clamping springs 104, and the rotation directions of the two clamping springs 104 are opposite. The two clamping springs 104 have a tendency to rotate toward the other clamping spring 104, so as to clamp the circuit between the two clamping springs 104 and the lower shell 102.

[0038] Because the fault indicator 100 is installed manually, the installer needs to step on a ladder to get close to the line, open the upper shell 101 of the fault indicator 100, place the line between the upper shell 101 and the lower shell 102, and then snap the upper shell 101 and the lower shell 102 together. The installation process requires the installer to operate with both hands, which may cause danger of falling from the ladder, and the installation efficiency is low.

[0039] Embodiment 1

[0040] To solve the above problems, this embodiment provides a tool for installing a fault indicator 100, such as Figure 2 to Figure 4 As shown, the installation tool includes a bracket 1 and a push-up assembly 2, the bracket 1 is provided with a first buckle 11, the first buckle 11 is configured to snap into the opened upper shell 101 of the fault indicator 100, the push-up assembly 2 includes a base 21 and an elastic member 22, the base 21 is slidably connected to the bracket 1, and the two ends of the elastic member 22 respectively abut the base 21 and the bracket 1.

[0041] The installation tool can use the first buckle 11 to buckle the opened upper shell 101 of the fault indicator 100, and clamp the fault indicator 100 between the first buckle 11 and the base 21 to keep it stable. The installer can hold the installation tool close to the line, make the line abut against the lower shell 102 of the fault indicator 100, and then continue to push the installation tool to make the line pass through the fault indicator 100 to drive the base 21 to compress the elastic member 22. At this time, the distance between the base 21 and the first buckle 11 increases, so that the upper shell 101 of the fault indicator 100 is separated from the first buckle 11 and buckled with the lower shell 102, and the installation of the fault indicator 100 is completed.

[0042] The installation tool can be installed with one hand, has high safety, is easy to operate, and improves installation efficiency.

[0043] Specifically, the elastic member 22 is a spring.

[0044] like Figure 2 to Figure 4 As shown, the installation tool also includes a second buckle 3, which is rotatably arranged on the bracket 1, and the second buckle 3 is configured to clamp the edge of the lower shell 102 of the fault indicator 100, and at this time, the clamping direction of the second buckle 3 is downward. Because the installation tool places the fault indicator 100 on the base 21 before installing the fault indicator 100, and the base 21 is supported by the elastic member 22 and is not stable enough, the second buckle 3 can press the fault indicator 100 against the base 21 by clamping the edge of the lower shell 102 of the fault indicator 100. At this time, the base 21 compresses the elastic member 22, which is equivalent to the elastic member 22 elastically pressing the base 21 and the fault indicator 100 against the second buckle 3, so that the fault indicator 100 is in a stable state. When the line abuts the lower shell 102, the fault indicator 100 presses the elastic member 22 downward to make the second buckle 3 detach from the edge of the lower shell 102, thereby ensuring that the fault indicator 100 can be detached from the installation tool. In order to further improve the stability of the fault indicator 100 inside the bracket 1 , the installation tool includes a plurality of second buckles 3 .

[0045] like Figure 2 to Figure 4As shown, the installation tool also includes a third buckle 4, which is rotatably arranged on the bracket 1, and the third buckle 4 is configured to clamp the open spring 104 of the fault indicator 100. The third buckle 4 can make the spring 104 of the fault indicator 100 in an open state, so that the operator can place the circuit between the spring 104 and the lower shell 102. When the circuit abuts the lower shell 102, the fault indicator 100 compresses the elastic member 22 downward, and the third buckle 4 is disengaged from the spring 104, so that the spring 104 can press the circuit against the lower shell 102. It can be understood that the installation tool is provided with at least two third buckles 4, and each third buckle 4 clamps a spring 104. In order to ensure the stability of the spring 104 when being clamped by the third buckle 4, in this embodiment, the installation tool includes four third buckles 4, and each spring 104 is clamped by two third buckles 4.

[0046] However, since the retaining spring 104 is rotationally connected to the lower shell 102, that is, when the fault indicator 100 moves downward, the retaining spring 104 may rotate relative to the lower shell 102, causing the third buckle 4 to be unable to disengage from the retaining spring 104, resulting in the installation tool ultimately being unable to disengage from the fault indicator 100, and the operator is required to manually disengage the third buckle 4 from the retaining spring 104, which reduces efficiency and increases danger.

[0047] like Figure 3 and Figure 4 As shown, to solve this problem, the installation tool also includes an unlocking member 5, which is rotatably arranged on the bracket 1, and is transmission-connected with the third buckle 4. When the base 21 moves toward the direction of the compression elastic member 22, it can abut against the unlocking member 5 and drive the third buckle 4 to rotate to unlock the retaining spring 104. The unlocking member 5 can ensure that when the fault indicator 100 moves downward to compress the elastic member 22, the third buckle 4 will definitely be separated from the retaining spring 104, so that the retaining spring 104 can press the circuit against the lower shell 102, and the installation tool can be separated from the fault indicator 100.

[0048] like Figure 3 and Figure 4 As shown, the installation tool further includes a transmission member 6, and both ends of the transmission member 6 are respectively pivotally connected to the unlocking member 5 and the third buckle 4. When the unlocking member 5 rotates under the drive of the base 21, the unlocking member 5 drives the transmission member 6 to move, so that the third buckle 4 rotates in a direction away from the clip 104, thereby ensuring that the third clip 4 is unlocked from the clip 104.

[0049] Specifically, in this embodiment, when the base 21 abuts against the unlocking member 5 to rotate one end of the unlocking member 5 downward, the other end of the unlocking member 5 drives the transmission member 6 to move upward, and the transmission member 6 pushes the third buckle 4 to rotate upward, thereby disengaging the third buckle 4 from the retaining spring 104.

[0050] like Figure 3 and Figure 4 As shown, the base 21 is provided with a receiving groove 211, and the receiving groove 211 is arranged in the same shape as the fault indicator 100. The bottom of the fault indicator 100 is a hemispherical shell made of transparent plastic or glass, and the receiving groove 211 of the base 21 is also a hemispherical groove, and the inner diameter of the receiving groove 211 is equal to the outer diameter of the hemispherical shell of the fault indicator 100. The hemispherical shell of the fault indicator 100 can fit with the inner wall of the receiving groove 211, thereby ensuring the stability of the fault indicator 100.

[0051] Preferably, the bracket 1 includes a sleeve 12 and at least two support members 13, at least two support members 13 are arranged at intervals along the outer circumference of the sleeve 12, the base 21 is slidably arranged in the sleeve 12, and the first buckle 11 is rotatably arranged on the top of one of the support members 13. The sleeve 12 can guide and protect the fault indicator 100 and the base 21, and the support member 13 is used to set the first buckle 11, the second buckle 3 and the third buckle 4. Specifically, each support member 13 is provided with two second buckles 3 and three buckles 4.

[0052] Furthermore, a plurality of linear bearings are arranged at intervals along the circumferential direction on the inner wall of the sleeve 12, and when the fault indicator 100 enters the sleeve 12, the outer wall of the fault indicator 100 rolls against the plurality of linear bearings. The linear bearings can not only guide the fault indicator 100, but also prevent the outer tube of the fault indicator 100 from being damaged due to friction between the fault indicator 100 and the inner wall of the sleeve 12.

[0053] Embodiment 2

[0054] This embodiment improves the structure of the bracket 1 on the basis of the first embodiment.

[0055] In this embodiment, a mounting portion 14 is provided at the bottom of the bracket 1, and the mounting portion 14 is used to install a support rod. It is understandable that the line is generally installed at a higher position, and when the operator uses the support rod to support the installation tool, he can stand on the ground to install the fault indicator 100, eliminating the process of climbing a ladder, which can improve efficiency and reduce risks.

[0056] Furthermore, the support rod is an insulating rod, and the support rod is threadedly connected to the mounting portion 14. The insulating rod can further improve the safety of the operator and reduce the safety risk of line leakage to the operator's work.

[0057] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
