DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to solve the problem of snow and ice crust treatment during the maintenance of power transmission lines, this embodiment provides a power line ice and snow cleaning device. Figure 1 As shown, the power line snow and ice clearing device comprises a drone body 1, a power line knocking mechanism 2 and an ice melting structure 3 mounted on the drone body 1. The drone body 1 adopts a commercially available multi-rotor drone, and the bottom of the drone body 1 is provided with a first fixed box 4 and a second fixed box 5 for installing the power line knocking mechanism 2 and the ice melting structure 3, as well as a landing support frame for landing support.

[0023] like Figure 1 and Figure 2As shown, the power line knocking mechanism 2 in this embodiment includes a rope winding assembly 6 and a knocking rod 7 installed in the first fixed box 4, and the knocking rod 7 can be raised and lowered relative to the drone body 1 through the rope winding assembly 6. Specifically, the rope winding assembly 6 includes a first winding box 11 fixedly installed inside the first fixed box 4, and a second winding roller 12 is rotatably connected inside the first winding box 11, and a rope 13 is wound around the second winding roller 12. One end of the rope 13 is fixedly installed on the second winding roller 12, and the other end passes through the first winding box 11 and the first fixed box 4 and is fixedly connected to the knocking rod 7; a first servo motor 14 is fixedly installed on one side of the first winding box 11, and the output end of the first servo motor 14 is fixedly connected to one end of the second winding roller 12.

[0024] When the drone body 1 flies above the power line, the first servo motor 14 is remotely started, and the second winding roller 12 is driven to rotate by the first servo motor 14, so that the suspension rope 13 is released, and the knocking rod 7 is lowered to the same level as the power line. Then, the drone body 1 flies left and right relative to the power line, so that the knocking rod 7 swings relative to the drone body 1, so that the knocking rod 7 knocks the power line below the drone body 1 to remove the snow on the power line. After the snow on the power line is removed, the first servo motor 14 drives the second winding roller 12 to rotate in the opposite direction, and the knocking rod 7 is reset by rewinding the suspension rope 13.

[0025] like Figure 1 and Figure 3 As shown, the ice melting structure 3 in this embodiment includes a hot air pipeline assembly 8 installed in a first fixed box 4, a multi-stage electric telescopic rod 9, and a cable ring sleeve 10; the cable ring sleeve 10 is an annular structure that can be opened or closed, which is moved to the power line 44 through the multi-stage electric telescopic rod 9 and is mounted on the power line 44.

[0026] Specifically, Figure 3 and Figure 4 As shown, the cable ring sleeve 10 includes an upper semicircular ring sleeve 20 and a lower semicircular ring sleeve 21. An arc-shaped piston cylinder 22 is fixedly installed on the outer wall of the upper semicircular ring sleeve 20, and a sliding cavity that matches the lower semicircular ring sleeve 21 is provided inside one side of the upper semicircular ring sleeve 20; the outer cylinder body wall of the arc-shaped piston cylinder 22 is fixedly connected to the multi-stage electric telescopic rod 9. One side of the lower semicircular ring sleeve 21 extends into the upper semicircular ring sleeve 20 and is slidably connected to the upper semicircular ring sleeve 20. The arc-shaped piston cylinder 22 is equipped with an arc-shaped piston rod 23, which is located on the outside of the sliding cavity of the lower semicircular ring sleeve 21, and the end of the arc-shaped piston rod 23 is fixedly connected to the other side of the sliding cavity of the lower semicircular ring sleeve 21. Figure 4 and Figure 5As shown, the left side of the upper semicircular ring sleeve 20 and the lower semicircular ring sleeve 21 is a sliding connection side, and the right side can form an opening 24 for the power line 44 to enter through the contraction of the arc-shaped piston rod 23.

[0027] Further, such as Figure 4 and Figure 5 As shown, the arc piston cylinder 22 in this embodiment is a hydraulic oil cylinder, and the arc piston cylinder 22 is provided with an oil pump 25 and an oil storage tank 26 on the side away from the sliding connection. When the oil pump 25 injects the oil in the oil storage tank 26 into the arc piston cylinder 22, the arc piston rod 23 extends relative to the arc piston cylinder 22, and the arc piston rod 23 drives the lower semicircular ring sleeve 21 to slide relative to the upper semicircular ring sleeve 20 toward the outside of the upper semicircular ring sleeve 20, forming a closed state of the cable ring sleeve 10. On the contrary, when the oil pump 25 sucks the oil in the arc piston cylinder 22 back to the oil storage tank 26, the arc piston rod 23 shrinks relative to the arc piston cylinder 22, and the arc piston rod 23 drives the lower semicircular ring sleeve 21 to slide relative to the upper semicircular ring sleeve 20 toward the inside of the upper semicircular ring sleeve 20, forming an open state of the cable ring sleeve 10, so that the power line 44 enters the cable ring sleeve 10 through the opening 24.

[0028] The function of the hot air pipeline assembly 8 is to heat the external air and transport it to the cable ring 10 so that the hot air is blown toward the power line 44. Figure 1 and Figure 3 As shown, the hot air pipeline assembly 8 includes a fan 27 disposed in the second fixed box 5, a heating pipe 28 connected to the fan 27, a gas hose 29 connected to the heating pipe 28, and an annular air ring 30 connected to the gas hose 29 and installed on the inner edges of the upper semicircular ring sleeve 20 and the lower semicircular ring sleeve 21. The fan 27 delivers external air to the annular air ring 30 through the heating pipe 28 and the gas hose 29; in order to cooperate with the cable ring 10 of the annular structure that can be opened or closed, as shown in FIG. Figure 4 and Figure 5 As shown, the annular air ring 30 in this embodiment includes an upper semicircular arc-shaped blind tube 31 installed on the inner edge of the upper semicircular ring sleeve 20, and a lower semicircular arc-shaped blind tube 32 installed on the inner edge of the lower semicircular ring sleeve 21; the upper semicircular arc-shaped blind tube 31 and the lower semicircular arc-shaped blind tube 32 adopt hard tube bodies of unequal diameters; one end of the upper semicircular arc-shaped blind tube 31 is connected with one end of the lower semicircular arc-shaped blind tube 32 by sliding sleeve, and the blind end of the lower semicircular arc-shaped blind tube 32 is fixedly connected with the end of the other side of the lower semicircular ring sleeve 21, which does not affect the expansion and contraction of the lower semicircular arc-shaped blind tube 32 relative to the upper semicircular arc-shaped blind tube 31, and realizes the installation of the lower semicircular arc-shaped blind tube 32 relative to the lower semicircular ring sleeve 21. A plurality of nozzles 33 are arranged at equal intervals in the annular direction on the upper semicircular arc-shaped blind tube 31 and the lower semicircular arc-shaped blind tube 32. As shown Figure 3 and Figure 6 As shown, considering the problem of air heating, a plurality of heating wires 34 are installed inside the heating tube 28 in this embodiment.

[0029] Since the upper semicircular arc-shaped blind tube 31 and the lower semicircular arc-shaped blind tube 32 use hard tubes of unequal diameters, when the cable ring 10 is opened or closed, the lower semicircular arc-shaped blind tube 32 is synchronously extended and retracted relative to the upper semicircular arc-shaped blind tube 31. The air is powered by the fan 27, and is heated to form hot air when passing through the heating tube 28, and finally blown to the power line 44 through the nozzles 33 circumferentially arranged on the upper semicircular arc-shaped blind tube 31 and the lower semicircular arc-shaped blind tube 32, so as to melt ice on the power line 44.

[0030] It should be noted that the power line de-icing function needs to be carried out in cooperation with the drone body 1 flying along the power line 44; specifically, after the drone body 1 flies above the power line 44, it first removes the snow on the power line 44, and then starts the multi-stage electric telescopic rod 9 to adjust the position of the cable ring 10; then, by controlling the arc piston cylinder 22 of the cable ring 10, the drone body 1 is cooperated to make the power line 44 enter the cable ring 10 and then start the de-icing operation. The hot air pipeline assembly 8 heats the external air and then transports it to the cable ring 10 to blow toward the power line 44; the de-icing structure 3 flies along the power line 44 through the drone body 1 to de-ice the power line 44. After the de-icing is completed, the power line 44 is moved out of the cable ring 10, and each mechanism is reset.

[0031] In the above process, the position of the cable ring 10 is adjusted by the multi-stage electric telescopic rod 9. In order to avoid the influence caused by the hose being too long or too short during the adjustment process, Figure 3 and Figure 7 As shown, the ice melting structure 3 in this embodiment also includes a hose reeling assembly 35 installed in the second fixed box 5, and the structure of the hose reeling assembly 35 is similar to that of the rope reeling assembly 6. Specifically, the hose reeling assembly 35 includes a second reeling box 36 fixedly installed in the two fixed boxes, the second reeling box 36 is rotatably connected with the first reeling roller 37, one side of the second reeling box 36 is fixedly connected with the third servo motor 38, and the output end of the third servo motor 38 is fixedly connected with one end of the first reeling roller 37. The difference is that: a rotary joint 39 is installed on one side of the second reeling box 36; a fixed pipe 40 is fixedly connected inside the first reeling roller 37, a gas hose 29 is wound around the first reeling roller 37, one end of the fixed pipe 40 is connected with one end of the gas hose 29, the other end of the fixed pipe 40 is connected with one end of the rotary joint 39, and the other end of the rotary joint 39 is fixedly connected with the heating pipe 28; one end of the gas hose 29 passes through the second reeling box 36 and the second fixed box 5 and is connected with the upper semicircular arc blind pipe 31. The rotary joint 39 can realize the function of retracting and extending the air delivery hose 29 without affecting the hot air delivery of the heating pipe 28.

[0032] Furthermore, as a preferred technical solution of this embodiment, in order to prevent the power line knocking mechanism 2 and the ice melting structure 3 from affecting the take-off and landing of the drone body 1, as Figure 1 , Figure 2 and Figure 3 As shown, the power line knocking mechanism 2 in this embodiment also includes a knocking rod storage assembly 15, and the ice melting structure 3 also includes a telescopic rod storage assembly 41. Among them, the knocking rod storage assembly 15 includes a group of second servo motors 17 symmetrically installed on both sides of the bottom of the first fixed box 4 through a first fixed block 16, and a first electric telescopic rod 18 installed on the output shaft of the second servo motor 17, and the telescopic end of the first electric telescopic rod 18 is installed with a first clamping block 19 capable of clamping the knocking rod 7. The telescopic rod storage assembly 41 includes a group of fourth servo motors 43 symmetrically installed on both sides of the bottom of the second fixed box 5 through a second fixed block 42, and the output end of the fourth servo motor 43 is fixedly connected to both sides of the multi-rod electric telescopic rod.

[0033] When the power line knocking mechanism 2 and the ice melting structure 3 are in a non-operating state, such as Figure 8 As shown, the first electric telescopic rod 18 extends to clamp the top two sides of the knocking rod 7, and the second servo motor 17 drives the first electric telescopic rod 18 to rotate, so that the knocking rod 7 is stored in a horizontal state, so as to avoid its length being greater than the landing support frame and affecting the landing of the drone body 1. Similarly, the fourth servo motor 43 drives the multi-rod electric telescopic rod and the cable ring 10 to rotate and store in a horizontal state, so as to avoid affecting the landing of the drone body 1.

[0034] In summary, the power line ice and snow cleaning device combines the power line knocking mechanism 2 and the ice melting structure 3, which can not only remove the accumulated snow by the knocking rod 7 by oscillation and knocking, but also melt the ice shell by the hot air pipeline assembly 8, thereby achieving a double cleaning effect, and significantly improving the efficiency and thoroughness of the power line ice and snow removal. The knocking rod 7 of the power line ice and snow cleaning device can be raised and lowered by the hanging rope winding assembly 6, and the cable ring 10 can be adjusted in position by the multi-stage electric telescopic rod 9, so that the device can adapt to power lines of different heights and types, and has strong versatility and adaptability.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
