Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0050] In the description of this embodiment, the terms "upper," "lower," "left," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and are therefore not to be construed as limitations on the present invention. Furthermore, the terms "first," "second," and the like are used solely for descriptive purposes and have no special meaning.

[0051] like Figures 1 to 5 As shown, this embodiment provides an overhead conductor grounding device, including a line clamp mechanism 100, a pulley 200, a ground wire connector female sleeve 300, a ground wire connector male connector 400 and a wire retracting and releasing mechanism 500.

[0052] The line clamp mechanism 100 can be moved into the air with the help of a drone and clamp the overhead wire 1;

[0053] The pulley 200 is fixed to one side of the line-parking clamp mechanism 100 along the first direction, and the rotation axis of the pulley 200 extends along the first direction.

[0054] The ground wire connector female sleeve 300 is fixed to one side of the line clamp mechanism 100 where the pulley 200 is installed and is located obliquely below the pulley 200 .

[0055] The ground wire connector male connector 400 can be snap-fitted with the ground wire connector female connector 300 , and the ground wire connector male connector 400 is used to connect the pull rope 2 and the ground wire 3 .

[0056] The wire retraction and release mechanism 500 is used to retract and release the pull rope 2 and the ground wire 3. The end of the ground wire 3 away from the pull rope 2 is grounded. The end of the pull rope 2 away from the ground wire connector male head 400 passes through the ground wire connector female sleeve 300 and passes around the pulley 200 to be connected to the counterweight 600. The pull rope 2 is used to pull the ground wire connector male head 400 upward until it is engaged with the ground wire connector female sleeve 300 to achieve grounding of the overhead wire 1.

[0057] In this embodiment, the pull rope 2 is connected to the ground wire 3, the pulley 200 and the ground wire connector female sleeve 300 are fixed on the line clamp mechanism 100, the pull rope 2 passes through the ground wire connector female sleeve 300 and bypasses the pulley 200 to be connected to the counterweight 600. With the cooperation of the counterweight 600 and the retractable wire mechanism 500, the ground wire connector male head 400 can be clamped with the ground wire connector female sleeve 300 through the pull rope 2, thereby realizing the grounding treatment of the overhead wire 1.

[0058] Compared with the prior art, the overhead conductor grounding device of this embodiment can replace manual tower climbing for conductor grounding operations, solving the high risk and low efficiency problems of manual tower climbing operations.

[0059] Further, as shown in Figure 2 The wire retaining clamp mechanism 100 includes a mounting plate 110, a hanging part 120, and an elastic clamp 130. The pulley 200 and the ground wire connector female sleeve 300 are installed on one side of the mounting plate 110 along a first direction. The hanging part 120 is connected to the mounting plate 110 and is used for hanging on the unmanned aerial vehicle. The elastic clamp 130 includes a downward-opening U-shaped frame 131, a clamping plate 132, and a first elastic part 133. The U-shaped frame 131 is fixed to the bottom of the mounting plate 110. Two clamping plates 132 are arranged in a second direction in the U-shaped frame 131. Each clamping plate 132 is connected to the side plate of the U-shaped frame 131 along the second direction through a first elastic part 133. The first direction is perpendicular to the second direction (the second direction is the left-right direction). Figure 2 When the overhead conductor 1 is clamped between the two clamping plates 132, the first elastic part 133 causes the clamping plate 132 to always have a tendency to move towards the overhead conductor 1.

[0060] It can be understood that the hanging part 120 is used for hanging on the unmanned aerial vehicle. The clamping plate 132 is arranged between the two side plates of the U-shaped frame 131. The first elastic part 133 is arranged between the clamping plate 132 and the side plate. The elastic clamping groove can be formed between the two clamping plates 132. When the overhead conductor 1 is opposite to the elastic clamping groove, the unmanned aerial vehicle releases the overhead conductor grounding device, and the overhead conductor 1 can be clamped with the elastic clamping groove by extruding the clamping plate 132.

[0061] Further, the lower end of the two clamping plates 132 can be arranged as a guide inclined surface inclined towards the side plate of the U-shaped frame 131, so that the overhead conductor 1 can be smoothly clamped between the two clamping plates 132.

[0062] In this embodiment, the overhead conductor grounding device further includes a counterweight hanging and pushing assembly 700, as shown in Figure 2 and Figure 3 The counterweight hanging and pushing assembly 700 is connected to the wire retaining clamp mechanism 100 and is used for hanging the counterweight 600 and pushing the counterweight 600 out to make the counterweight 600 hang in the air when the overhead conductor 1 is clamped between the two clamping plates 132. When the unmanned aerial vehicle pulls the overhead conductor grounding device to rise, the counterweight 600 can be hung on the counterweight hanging and pushing assembly 700. When the overhead conductor 1 is clamped between the two clamping plates 132, the counterweight 600 is automatically pushed out to make the counterweight 600 hang in the air. This facilitates the subsequent release of the pull rope 2 to be in a tensioned state, thereby improving the operation convenience.

[0063] Further, as shown in Figure 2As shown, the two sides of the hanging part 120 are connected with the mounting plate 110 and extend downward to the outside of the U-shaped frame 131; the first elastic part 133 includes a guide rod 1331 and a first spring 1332, one end of the guide rod 1331 is fixedly connected with the clamping plate 132, the other end penetrates through the side plate of the U-shaped frame 131 and is fixedly connected with the hanging part 120, the first spring 1332 is sleeved on the guide rod 1331, and the two ends of the first spring 1332 are respectively abutted with the clamping plate 132 and the side plate of the corresponding U-shaped frame 131; the counterweight hanging and pushing assembly 700 includes a pushing rod 710 and a supporting part 720, the pushing rod 710 is fixed on one side of the hanging part 120, the supporting part 720 is fixed on one side of the mounting plate 110 and is adjacent to the pushing rod 710, and the counterweight 600 is hung on the supporting part 720; when the overhead conductor 1 is clamped between the two clamping plates 132, the clamping plate 132 extrudes the first spring 1332 to drive the guide rod 1331 to push the two sides of the hanging part 120 to move in a direction away from the mounting plate 110, the hanging part 120 pushes the pushing rod 710 to push the counterweight 600 away from the supporting part 720, so that the counterweight 600 is in a suspended state.

[0064] Wherein, before the unmanned aerial vehicle releases the overhead conductor grounding device, the counterweight 600 connected with the pull rope 2 is always hung and placed on the supporting part 720, so as to avoid that the counterweight 600 affects the flight stability of the unmanned aerial vehicle during the flight process of the unmanned aerial vehicle. The pushing rod 710, the supporting part 720 and the line retaining clamp mechanism 100 cooperate with each other, when the unmanned aerial vehicle releases the overhead conductor grounding device, the clamping of the overhead conductor 1 and the line retaining clamp mechanism 100 can automatically trigger the separation of the counterweight 600 and the supporting part 720, without manual operation, and the convenience of the overhead conductor 1 grounding operation is improved.

[0065] Further, as shown in the figure, Figure 4 The counterweight 600 includes a lead hammer 610, an intermediate connecting part 620, a connecting rod 630 and a hanging ring 640, the lead hammer 610 is connected with the connecting rod 630 through the intermediate connecting part 620, the hanging ring 640 is fixed on the side of the connecting rod 630 away from the lead hammer 610, the supporting part 720 includes a fixed plate 721 and a supporting plate 722 which are connected vertically, the fixed plate 721 is fixedly connected with one side of the mounting plate 110 along the second direction, the hanging ring 640 is connected with the pull rope 2, the connecting rod 630 is hung on the supporting plate 722, and the pushing rod 710 is used to selectively push the connecting rod 630 away from the supporting plate 722.

[0066] In order to improve the suspension stability of the counterweight 600 of the unmanned aerial vehicle when the overhead ground wire grounding device is flying, the structure of the supporting part 720 can be improved. For example, the supporting plate 722 includes two supporting blocks arranged in an upper and lower interval, and the two supporting blocks are vertically connected with the fixed plate 721. When the connecting rod 630 is located between the two supporting blocks, the two supporting blocks have a certain clamping effect on the connecting rod 630, and when the push rod 710 can overcome the clamping force to push the connecting rod 630 away from the supporting plate 722.

[0067] In the embodiment, the number of the supporting plate 722 is two, and the two supporting plates 722 are arranged at intervals and are respectively used for suspending the two ends of the connecting rod 630, which can further improve the suspension stability of the counterweight 600.

[0068] Exemplarily, the distance between the two supporting blocks decreases first, then gradually increases, and finally remains stable in the direction from the entrance to the fixed plate 721, which can further improve the suspension stability of the counterweight 600 and the smoothness of the separation of the counterweight 600 from the supporting plate 722.

[0069] As shown in FIG. 8, Figure 2 , the overhead ground wire grounding device further includes a first pull rope guide part 800 and a second pull rope guide part 900 fixed on the mounting plate 110. The ground wire connecting part female sleeve 300 and the first pull rope guide part 800 are inclined in the same direction. One end of the first pull rope guide part 800 is connected with the ground wire connecting part female sleeve 300, and the other end extends to the adjacent pulley 200. The second pull rope guide part 900 is inclinedly arranged. The first pull rope guide part 800 and the second pull rope guide part 900 are arranged at an included angle of not more than 90°. One end of the pull rope 2 is connected with the ground wire connecting part male head 400, and the other end passes through the ground wire connecting part female sleeve 300 and the first pull rope guide part 800, winds around the pulley 200, and then passes through the second pull rope guide part 900 and is connected with the counterweight 600. The entrance end of the ground wire connecting part female sleeve 300 and the second pull rope guide part 900 respectively extend to the outside of the mounting plate 110.

[0070] By arranging the first pull rope guide part 800 and the second pull rope guide part 900, the movement of the pull rope 2 can be guided, and the phenomenon of knotting caused by the too close distance between the one end of the pull rope 2 and the other end of the pull rope 2 when the counterweight 600 descends can be avoided. The first pull rope guide part 800 and the second pull rope guide part 900 can be a tubular structure or a U-shaped groove structure.

[0071] Further, the elastic wire clamp 130 further comprises two arc-shaped pressing plates 134, which are symmetrically arranged between the two clamping plates 132. When the overhead conductor 1 is clamped between the two clamping plates 132, the convex surface of the two arc-shaped pressing plates 134 and the opposite surface of the two clamping plates 132 are in contact with the outer periphery of the overhead conductor 1, so that the clamping stability of the overhead conductor 1 and the elastic wire clamp 130 can be further improved.

[0072] In order to improve the grounding stability, the outlet end of the ground wire connector female sleeve 300 is designed as a tapered structure, the inlet end of the ground wire connector female sleeve 300 is designed as a cylindrical structure, a plurality of circular mounting holes are arranged on the inner wall of the inlet end of the ground wire connector female sleeve 300 at intervals, a second spring and a ball are mounted in the mounting hole, the diameter of the ball is smaller than the diameter of the mounting hole, the ball partially protrudes from the mounting hole, a plugging cover is arranged on the outer wall of the inlet end of the ground wire connector female sleeve 300, the plugging cover is fixed to the outer wall of the inlet end of the ground wire connector female sleeve 300 to block the end of the mounting hole away from the ball, and the two ends of the second spring are in abutment with the ball and the plugging cover, respectively; the end of the ground wire connector male head 400 connected to the pull rope 2 is designed as a tapered structure matched with the outlet end of the ground wire connector female sleeve 300, and the end of the ground wire connector male head 400 connected to the ground wire 3 is designed as a cylindrical structure, and a clamping groove is arranged on the outer periphery of the cylindrical structure corresponding to the ball, and when the ground wire connector male head 400 is inserted into the ground wire connector female sleeve 300, the ball is clamped in the clamping groove.

[0073] In the embodiment, the end of the ground wire connector male head 400 connected to the pull rope 2 is designed as a tapered structure, the inlet end of the ground wire connector female sleeve 300 is designed as a cylindrical structure, when the pull rope 2 pulls the ground wire connector male head 400 to be quickly inserted into the ground wire connector female sleeve 300, the ground wire connector male head 400 will extrude the ball during the insertion process, so that the ball moves away from the ground wire connector male head 400 against the force of the second spring, and when the ground wire connector male head 400 moves to the position where the ball is just located in the clamping groove on the outer periphery of the ground wire connector male head 400, the ground wire connector male head 400 is clamped and fixed with the ground wire connector female sleeve 300, and the grounding operation of the overhead conductor 1 is realized.

[0074] The mounting hole, the second spring, the ball and the clamping groove in the embodiment are not shown in the figure, and those skilled in the art can directly and meaninglessly obtain them according to the description of the embodiment, which will not be described here.

[0075] The take-up and pay-off mechanism 500 has two take-up and pay-off wheels 510, and the two take-up and pay-off wheels 510 are arranged on the same axis. Figure 5As shown, each take-up reel 510 has two spaced take-up grooves 520 along its axial direction, and the pull rope 2 and the ground wire 3 are respectively wound in one of the take-up grooves 520 on one of the take-up reels 510. By arranging two take-up reels 510 and designing two spaced take-up grooves 520 on each take-up reel 510, independent take-up operations of the pull rope 2 and the ground wire 3 are facilitated.

[0080] In the embodiment, the grounding of the ground wire 3 refers to connecting the ground wire 3 with the angle steel near the bottom of the tower 4.

[0081] Further, the take-up reel mechanism 500 includes a first take-up reel and a second take-up reel Figure 1 、 Figure 6 and Figure 7 not shown in the above embodiment, and can refer to Figure 5 , the first take-up reel has a first take-up groove and a second take-up groove spaced along its axial direction, the second take-up reel has a third take-up groove and a fourth take-up groove spaced along its axial direction, the pull rope 2 includes a pilot rope 21 and a load-bearing rope 22, and the overhead conductor grounding method specifically includes the following steps:

[0082] (1), winding the load-bearing rope 22 in the first take-up groove along the A direction, winding the ground wire 3 in the third take-up groove along the A direction after grounding, and connecting one end of the load-bearing rope 22 with the pilot rope 21 and the other end of the load-bearing rope 22 with the ground wire 3 through the ground wire connector male head 400;

[0083] (2), connecting the pilot rope 21 away from the load-bearing rope 22 with the counterweight 600 through the ground wire connector female sleeve 300 and the pulley 200.

[0084] (3), the unmanned aerial vehicle is used to suspend the line clamp mechanism 100, the pulley 200 and the ground wire connector female sleeve 300 to the upper of the overhead conductor 1, the unmanned aerial vehicle is lowered to release the line clamp mechanism 100, and the line clamp mechanism 100 is clamped on the overhead conductor 1 through its own gravity;

[0085] (4), as Figure 1 , the first take-up reel is rotated to release the pilot rope 21, the counterweight 600 is removed after falling to the ground, the pilot rope 21 is wound in the second take-up groove in the B direction, the A direction is opposite to the B direction, at this time, the first take-up reel tightens the pilot rope 21 while releasing the load-bearing rope 22;

[0086] (5), as Figure 6 , when the end of the load-bearing rope 22 connected with the pilot rope 21 moves to the ground, the load-bearing rope 22 is wound in the fourth take-up groove in the B direction, the second take-up reel tightens the load-bearing rope 22 while releasing the ground wire 3 Figure 7 )(the second take-up reel also performs the take-up operation on the pilot rope 21), so that the male head 400 of the ground wire connector is clamped and fixed with the female sleeve 300 of the ground wire connector.
