DETAILED DESCRIPTION

[0018] The application will be described in detail below in combination with the drawings and examples: As Figures 1 to 5 shown, the foreign matter removing device of the multi-functional section combination of the overhead line distribution network of the application comprises an insulating rod 1, the insulating rod 1 is of a detachable split structure, so as to adjust the length according to the work requirement, wherein the split insulating rod 1 is preferably connected by threads; the top of the insulating rod 1 is coaxially provided with a support seat 2, the support seat 2 is provided with a support arm 3, the support arm 3 can be adjusted by rotating relative to the support seat 2, so as to facilitate the workers to flexibly adjust the working posture of the tool according to the position and angle of the foreign matter on the overhead line, and improve the convenience of operation, preferably, the support arm 3 is hingedly arranged with the support seat 2, and in the initial state, the support arm 3 and the support seat 2 are arranged in a vertical state; the support arm 3 is provided with a mounting seat 4 on one side, the mounting seat 4 is provided with a mounting groove, wherein the distance of the mounting groove is adjustable, so as to enable the device to adapt to various types and different specifications of the obstacle removing tool, including the application range of the application. In addition, the insulating rod 1 and the support seat 2 in the application are connected by a quick connector 5, the support seat 2 and the insulating rod 1 are split, so as to improve the convenience of tool connection and eliminate the operation obstacles of the integral structure. The quick connector 5 adopts the existing technology of the wrench type quick connector.

[0019] Further, the lower part of the insulating rod 1 is slidably provided with an adjusting handle 6, and the adjusting handle 6 is provided with a rotatable adjusting winding wheel 7, and the winding wheel 7 is wound with a pull rope 8, and the free end of the pull rope 8 extends upward along the length direction of the insulating rod 1 and is reversely connected with the supporting arm 3; the setting of the winding wheel 7 can release or wind the pull rope 8 by rotating the winding wheel 7 when the insulating rod 1 of different lengths needs to be replaced, so as to adjust the moving length of the pull rope 8, and then adapt to the length change of the insulating rod 1, avoid the pull rope 8 being too loose or too tight due to the length adjustment of the insulating rod 1, and ensure that the pull rope 8 can always effectively control the supporting arm 3. This design effectively solves the obstruction of the length adjustment of the insulating rod 1 to the operation of the supporting arm 3, ensures the stable operation of the device under different specifications of the insulating rod 1 combination, and further enhances the versatility and adaptability of the equipment. In addition, the sliding setting of the adjusting handle 6 cooperates with the winding wheel 7 and the pull rope 8 to build a set of efficient angle adjusting mechanism of the supporting arm 3. The worker does not need to interrupt the work or approach the supporting arm 3, but only needs to pull down the adjusting handle 6 at the lower part of the insulating rod 1 to drive the pull rope 8 to move, and then pull the supporting arm 3 to rotate along the hinge point, so as to realize the real-time adjustment of the angle of the supporting arm 3. This online adjustment method saves the cumbersome steps of stopping, reassembling or manually adjusting the angle of the supporting arm 3 of the traditional tool, so that the worker can optimize the tool working posture at any time according to the position and angle change of the foreign matter, and the operation is more flexible and convenient, which greatly reduces the operation difficulty in the operation process. At the same time, the online adjustment function enables the worker to quickly adjust the angle of the supporting arm 3 to adapt to the operation demand when removing different positions and different types of foreign matters, which reduces the time of repeatedly moving the equipment or replacing the tool due to the inadaptability of the angle. At the same time, the precise adjustment of the length of the pull rope 8 by the winding wheel 7 ensures the stability and accuracy of each angle adjustment, avoids the shaking or inaccurate positioning of the supporting arm 3 due to the improper length of the pull rope 8, and improves the accuracy of the obstacle removal operation. The combination of the two significantly optimizes the obstacle removal operation process, shortens the single operation time, and thus effectively improves the overall efficiency of the obstacle removal operation of the distribution network overhead line.

[0020] Further, the support seat 2 is provided with a guide wheel 9, and the pull rope 8 is fixedly connected with the support arm 3 after winding around the guide wheel 9. The guide wheel 9 can provide clear and stable path guidance for the reversing of the pull rope 8. In the process of adjusting the angle of the support arm 3, the pull rope 8 needs to extend upward along the length direction of the insulating rod 1 and then be connected with the support arm 3. The arrangement of the guide wheel 9 can make the reversing process more smooth and orderly, avoiding the problems such as deviation, winding or jamming of the pull rope 8 due to reversing. This precise guidance ensures that the pull rope 8 can always move along the preset trajectory under stress, so that the pulling force applied by the adjusting handle 6 can be stably and efficiently transmitted to the support arm 3, ensuring the accuracy and reliability of the angle adjustment of the support arm 3. In addition, through the rotation of the guide wheel 9, the sliding friction between the pull rope 8 and the support seat 2 is converted into rolling friction, greatly reducing the friction resistance and the degree of wear of the pull rope 8. The pull rope 8 is effectively protected, the service life is prolonged, the equipment failure and replacement frequency caused by the damage of the pull rope 8 are reduced, and the maintenance cost is reduced.

[0021] Further, the sliding sleeve 10 of the adjusting handle 6 is provided with a support plate 11, the support plate 11 is of L-shaped structure, a positioning pin 12 is movably arranged on the support plate 11, and a positioning tooth 13 is arranged at the end of the positioning pin 12; a rotating shaft 14 is fixedly arranged on the sliding sleeve 10, and the winding wheel 7 is rotatably connected with the rotating shaft 14 through a bearing; wherein the winding wheel 7, the rotating shaft 14 and the sliding sleeve 10 are all provided with through holes for the positioning pin 12 to pass through, the insulating rod 1 is vertically provided with a positioning groove 15 which can be engaged with the positioning tooth 13; the part of the positioning pin 12 located inside the support plate 11 is further provided with a positioning disc 16, and the end surface of the positioning disc 16 in contact with the winding wheel 7 is provided with a tooth groove 17 which can be engaged with each other. After the worker adjusts the position of the sliding sleeve 10 (i.e. the angle of the supporting arm 3 is adjusted to the right position), the positioning pin 12 is inserted into the through holes of the sliding sleeve 10, the rotating shaft 14 and the winding wheel 7, and the positioning tooth 13 at the end of the positioning pin 12 is precisely engaged with the vertical positioning groove 15 on the insulating rod 1, so as to firmly lock the position of the sliding sleeve 10 on the insulating rod 1. The problem that the worker needs to continuously apply pressure to the adjusting handle 6 to maintain the angle of the supporting arm 3 during work can be solved, and the mechanical positioning is used to replace the manual support, so as to greatly reduce the operation strength of the worker, avoid the angle deviation of the supporting arm 3 caused by hand fatigue, ensure that the supporting arm 3 always maintains the preset posture during the operation process, and provide a stable tool operation basis for foreign matter removal operation. In addition, when the positioning pin 12 is inserted in place, the tooth groove 17 of the positioning disc 16 is engaged with the tooth groove 17 of the winding wheel 7, and the mechanical locking action of the tooth surface can effectively limit the rotation of the winding wheel 7 around the rotating shaft 14. This design avoids the accidental rotation of the winding wheel 7 caused by external force vibration, self-weight or operation collision, prevents the pull rope 8 from being accidentally released or tightened, ensures that the length of the pull rope 8 always matches the angle of the supporting arm 3 after adjustment, further consolidates the stability of the position of the supporting arm 3, and eliminates the risk of angle deviation from the driving end of the pull rope 8. The positioning pin 12 can simultaneously realize the double positioning of the sliding sleeve 10 and the winding wheel 7 through the insertion action, and the operation steps are simplified and the operation convenience is improved without separately operating two sets of positioning mechanisms. In the present application, in order to ensure the neatness of the whole device, the support base 2, the quick connector 5 and the insulating rod 1 are all hollow structures, and through holes 18 are arranged on the support base 2 and the insulating rod 1 at the bottom to allow the pull rope 8 to pass in and out, so as to avoid the pull rope 8 from being exposed and entangled with other components during work, and ensure the safety of use.

[0022] Further, a fixed handle 19 is arranged on the lower part of the insulating rod 1 of the adjusting handle 6, so as to facilitate the worker to hold the handle with hands and improve the convenience of pulling and adjusting the adjusting handle 6. In addition, the positioning pin 12 is preferably elastically arranged on the support plate 11 by a spring 20 to realize self-resetting, while ensuring the stability of the positioning pin 12; the supporting arm 3 and the support base 2 are elastically connected through a torsional spring, and the supporting arm 3 can be reset under the elastic restoring force of the torsional spring after the positioning is released.
