Description

Technical Field

[0001] The utility model belongs to the technical field of deicing devices, and in particular relates to a deicing device for a high-voltage line. Background Art

[0002] Drones have shown significant advantages in deicing high-voltage lines. Compared with traditional manual deicing methods, drone deicing not only improves work efficiency but also reduces the safety risks of operators.

[0003] At present, the operation process of drone deicing usually involves the use of special drones, mounted with insulating rods or other deicing equipment, and precisely maneuvering these equipment to hit the ice-covered wires to achieve the deicing effect. In this process, the high flexibility and efficiency of drones are fully demonstrated, which can quickly respond to various emergencies and conduct comprehensive inspections and deicing operations on transmission lines under severe weather conditions.

[0004] When using drones to de-ice high-voltage lines, it is necessary to control the drone's movement and ensure that the insulating rod can shake and hit the high-voltage line. This process requires high operation, and the insulating rod will inevitably vibrate after contacting the high-voltage line during the movement, which will cause the drone to fly unsteadily; if the control is not good, it is very easy to crash. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a high-voltage line deicing device, which does not require the movement of the drone to cause the knocking rod to collide with the high-voltage line; instead, it uses an elastic release method to achieve knocking.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A high-voltage line deicing device comprises a support frame, a knocking elastic rod and a winch device, wherein one end of the support frame is fixedly connected to a connecting sleeve, and one end of the knocking elastic rod can extend into the connecting sleeve and be connected to the support frame; the winch device is arranged at the other end of the support frame, and the other end of the knocking elastic rod is connected to a rope in the winch device, and the knocking elastic rod can be driven to bend through the winch device.

[0008] The hoisting device includes a driving motor and a winding drum, on which a rope is wound; the winding drum is rotatably connected to a support frame; a housing of the driving motor is fixedly connected to the support frame, and an output shaft of the driving motor is connected to the winding drum through a gear mechanism, so as to drive the winding drum to rotate and wind the rope.

[0009] The gear mechanism includes a sliding gear and a driving gear, wherein the driving gear is fixedly connected to the winding drum; the sliding gear is slidingly connected to the output shaft of the driving motor and can mesh with the driving gear; the sliding gear is connected to a pushing mechanism, through which the sliding gear can be driven to move axially along the output shaft.

[0010] The pushing mechanism includes a push-pull electromagnet and a shift fork. The shell of the push-pull electromagnet is fixedly connected to the support frame; the shift fork is rotationally connected to the sliding gear, and the sliding gear is provided with a corresponding connecting groove; the moving iron core of the push-pull electromagnet is fixedly connected to the upper end of the shift fork.

[0011] The lower end of the connecting sleeve is in a bell-mouth shape.

[0012] One end of the knocking elastic rod is connected to the support frame through an elastic rope or a tension spring.

[0013] A pair of connecting components are arranged on the support frame; the connecting components include a connecting seat and a connecting pipe, the connecting seat is slidably connected to the support frame, and a top screw is arranged on the connecting seat; the connecting pipe is fixedly connected to the connecting seat; the connecting pipe is connected to a pressure plate by bolts.

[0014] A rubber bellows connected to the connecting pipe is fixed on the connecting seat.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The other end of the knocking elastic rod is connected to the rope in the winch device, and the winch device can drive the knocking elastic rod to bend, so that it generates elastic potential energy. The drone moves to the high-voltage line, and the drone does not need to move at this time. By knocking the elastic rod, the elastic potential energy is released to contact and collide with the high-voltage line to de-ice. Therefore, the requirements for drone control can be effectively reduced.

[0017] At the same time, one end of the striking elastic rod is connected to the support frame through an elastic rope or a tension spring; that is, a "soft" connection is adopted between the striking elastic rod and the support frame, thereby reducing the impact on the drone during the striking process.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] like Figure 1-9 As shown, a high-voltage line deicing device includes a support frame 1, a striking elastic rod 2 and a winch device 3, and the support frame 1 is used to be fixed on the tripod of a drone.

[0030] A connecting sleeve 4 is fixedly connected to one end of the support frame 1, and one end of the knocking elastic rod 2 can be inserted into the connecting sleeve 4 and connected to the support frame 1; the hoisting device 3 is arranged at the other end of the support frame 1, and the other end of the knocking elastic rod 2 is connected to the rope 5 in the hoisting device 3. When the hoisting device 3 is wound around the rope 5, since one end of the knocking elastic rod 2 is located in the connecting sleeve 4, it will be gradually bent and elastically deformed. The material of the knocking elastic rod 2 can be made of an insulating material with relatively high elasticity or can be composed of a cylindrical spring outer shell with a rubber sleeve; the specific structure can be adjusted and selected according to actual conditions.

[0031] The specific operation process is as follows: the device is brought to the top of the required deicing line by a drone; then the rope 5 is released by the winch device 3, and the elastic rod 2 is knocked to release the elastic potential energy to knock on the line for deicing. In this process, the drone does not need to be moved for knocking, thus greatly reducing the difficulty of operation.

[0032] Furthermore, the hoisting device 3 includes a driving motor 6 and a winding drum 7, and the rope 5 is wound on the winding drum 7; the winding drum 7 is rotatably connected to the support frame 1; and the housing of the driving motor 6 is fixedly connected to the support frame 1. When the rope 5 needs to be wound, the driving motor 6 is turned on, and the output shaft of the driving motor 6 drives the winding drum 7 to rotate through the gear mechanism 8 to wind the rope 5. When release is required, the driving motor 6 is turned off; and the power is disconnected through the gear drive mechanism. At this time, under the action of knocking the elastic rod 2 to release the elastic potential energy, the winding drum 7 is driven to rotate in the opposite direction to release the rope 5. Specifically: a through hole is provided on the support frame 1, and the rope 5 can pass through the through hole and be wound on the winding drum 7.

[0033] Furthermore, the gear mechanism 8 specifically includes a sliding gear 9 and a driving gear 10, wherein the driving gear 10 is fixedly connected to the winding drum 7; the sliding gear 9 is slidably connected to the output shaft of the driving motor 6 and can mesh with the driving gear 10; and the sliding gear 9 is connected to a pushing mechanism. The output shaft can specifically be a spline shaft.

[0034] When winding is required, the sliding gear 9 is driven by the push mechanism to move axially along the output shaft, so that the sliding gear 9 meshes with the driving gear 10 to drive the winding drum 7 to rotate, and the rope 5 is wound on the winding drum 7. When releasing is required, the sliding gear 9 is driven by the push mechanism to move in the opposite direction along the axial direction of the output shaft, so that the sliding gear 9 does not mesh with the driving gear 10, and the winding drum 7 is driven to rotate in the opposite direction under the action of knocking the elastic rod 2.

[0035] Furthermore, the pushing mechanism includes a push-pull electromagnet 11 and a shift fork 12. The outer shell of the push-pull electromagnet 11 is fixedly connected to the support frame 1; the shift fork 12 is rotatably connected to the sliding gear 9, and the sliding gear 9 is provided with a corresponding connection groove 13; the moving iron core of the push-pull electromagnet 11 is fixedly connected to the upper end of the shift fork 12. The shift fork 12 and the sliding gear 9 are driven to move by the telescopic movement of the moving iron core of the push-pull electromagnet 11, thereby realizing the engagement or disconnection of the sliding gear 9 and the driving gear 10.

[0036] Specifically: when the push-pull electromagnet 11 is energized, the moving iron core moves (and compresses the return spring provided thereon) so that the shift fork 12 pushes the sliding gear 9 to engage with the driving gear 10; conversely, when the push-pull electromagnet 11 is de-energized, the return spring thereon releases its elastic potential energy, driving the moving iron core to move in the reverse direction, so that the shift fork 12 pushes the sliding gear 9 in the reverse direction, and the sliding gear 9 does not engage with the driving gear 10.

[0037] Furthermore, one end of the knocking rod can be fixedly connected, but this will cause a large shake during the knocking process, which is easy to affect the flight stability of the drone. To this end, one end of the knocking elastic rod 2 is connected to the support frame 1 through an elastic rope or tension spring 14; the two ends of the elastic rope or tension spring 14 are fixedly connected to the knocking elastic rod 2 and the support frame 1 respectively.

[0038] Taking the tension spring 14 as an example, during the release process, the shaking caused by the knocking elastic rod 2 is first transmitted to the drone through the tension spring 14, and the tension spring 14 will be stretched and swing, realizing a "soft" connection between the knocking elastic rod 2 and the support frame 1; therefore, the tension spring 14 can play a certain buffering role to prevent the shaking from being directly transmitted to the drone. At the same time, after the knocking contact, the tension spring 14 resets to ensure that one end of the knocking elastic rod 2 can extend into the connecting sleeve 4 (that is, one end of the knocking elastic rod 2 is restricted), so as to ensure that the knocking elastic rod 2 can be driven to bend when winding and stretching.

[0039] Furthermore, the lower end of the connecting sleeve 4 is preferably in a bell-mouth shape, which is conducive to the knocking elastic rod 2 being driven by the tension spring 14 to enter the connecting sleeve 4 to achieve reset. Of course, this is a setting made to prevent one end of the knocking elastic rod 2 from exceeding the connecting sleeve 4 too much. The length of the connecting sleeve 4 can be set as needed to ensure that after the tension spring 14 is stretched, one end of the knocking elastic rod 2 is still located in the connecting sleeve 4 or extends a small distance from the connecting sleeve 4.

[0040] Furthermore, the support frame 1 and the drone tripod can be connected by bolts 21 or by clamping. The following structure is preferably used:

[0041] A pair of connecting components 15 are provided on the support frame 1; each connecting component 15 includes a connecting seat 16 and a connecting pipe 17, the connecting seat 16 is slidably connected to the support frame 1, and the connecting seat 16 is connected to a top screw 18 through a threaded through hole. The position of the connecting seat 16 can be slidably adjusted according to the distance of the drone tripod, and the top screw 18 can be tightened to fix it after adjustment, and the top screw 18 passes through the threaded through hole and abuts against the support frame 1.

[0042] The connection tube 17 and the connection seat 16 can be fixedly connected; the connection tube 17 is connected to the pressure plate 19 by bolts 21. During installation, one of the UAV tripods is placed between the connection tube 17 and the pressure plate 19, and then the bolts 21 are tightened so that the connection tube 17 and the pressure plate 19 clamp the UAV tripod. The connection tube 17 and the pressure plate 19 are both provided with semicircular grooves that match the UAV tripod. Another connection assembly 15 is connected to another UAV tripod in the same installation method as above.

[0043] The tension spring 14 is used to achieve buffering between the connecting frame and the striking elastic rod 2; in order to further improve the buffering effect; a rubber bellows 20 connected to the connecting tube 17 is fixed on the connecting seat 16, and the two ends of the rubber bellows 20 are respectively fixedly connected to the connecting seat 16 and the connecting tube 17. The setting of the rubber bellows 20 can achieve buffering between the connecting seat 16 and the connecting tube 17.

[0044] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
