Abstract
Description
Technical Field
[0001] The invention relates to the field of live hanging installation of warning devices for high-voltage equipment of cables and wires-related electrical components, and in particular to a live hanging device and method for warning lights on overhead power transmission lines. Background Art
[0002] Affected by factors such as early planning, technical limitations, and urban construction, the insufficient distance between overhead transmission lines and the ground poses a safety hazard. Passing vehicles with excessive cargo or large-scale mechanical construction are prone to line collision accidents. In response to this phenomenon, hanging warning lights on transmission lines to alert passing vehicles is an effective preventive measure. However, the insufficient distance between overhead transmission lines and the ground only applies to large vehicles. For manual construction, the distance between warning lights and the ground is much higher than the manual operation range.
[0003] Patent CN115854304A discloses a method for installing a warning light for a power transmission and distribution line used in conjunction with a drone. The principle of this patent is to fix the warning light in the lampshade base above the drone. After the drone flies under the power line, the warning light wire clip hook is hung on the power line by controlling the drone to rise. Since the warning light and the drone are rigidly connected, although the rigid connection has high strength and stability, it is very easy for the drone to shake and deviate from the preset flight position due to strong winds and the pilot's operating skills and experience. Once the drone wing accidentally touches the wire, a crash will occur. This warning light hanging method requires a high level of pilot skill, is difficult to operate technically, and has a high risk of bombing. Summary of the invention
[0004] In view of the above problems, the present invention provides a device and method for hanging a warning light on an overhead power transmission line. The device and method can overcome the technical difficulties in the prior art that when a drone is mounted with a warning light, the wing is too close to the wire, and due to strong winds and the pilot's operating skills and experience, the wing of the drone is easily prone to accidentally touch the wire and cause a crash after the drone deviates from the preset position.
[0005] A device for hanging a warning light on an overhead power transmission line while it is energized, comprises an equipment mounting frame, a warning light bracket is connected to the lower part of the equipment mounting frame, the warning light is embedded in the upper surface of the warning light bracket, a lifting mechanism is arranged inside the equipment mounting frame, and the warning light bracket can be lifted and lowered along the equipment mounting frame under the drive of the lifting mechanism to realize the installation of the warning light.

[0010] Preferably, the auxiliary positioning mechanism comprises a positioning ring with a side opening, the positioning ring is provided with a guide tube penetrating from top to bottom, and the adjustable connecting line passes through the guide tube. Preferably, the lower end of the guide tube is lower than the lower end of the positioning ring, and the upper end of the guide tube is higher than the upper end of the positioning ring.
[0011] Preferably, a guide column is provided at the upper end of the warning light bracket, and the diameter of the guide column is smaller than the inner diameter of the guide tube.
[0012] Preferably, there are two groups of adjustable connecting lines, and the two groups of adjustable connecting lines are symmetrically arranged on both sides of the horizontal rotating shaft.
[0013] The present application also discloses a method for hanging a warning light on an overhead transmission line using the above device, which is as follows: Step 1: Install the warning light in the warning light bracket, adjust the height of the warning light bracket under the free hanging condition, and stop adjusting when the height of the warning light wire clamp is lower than the lower end of the guide tube; Step 2: The drone drives the entire device to fly above the power line, and the positioning ring is inserted into the power line; Step 3, control the motor to rotate forward, the adjustable connecting wire drives the warning light bracket to rise, and the warning light wire clamp is triggered by the external force of the power line to clamp the power line; Step 4: Control the motor to reverse, and adjust the connecting wire to drive the warning light bracket to descend until the warning light is detached. The drone drives the equipment to detach from the power line, and the installation is completed.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Different from the traditional solution of first controlling the drone to fly under the power line and then raising it to hang the warning light wire clip on the power line, this technical solution is to fly the drone above the power line, establish a flexible connection between the drone and the warning light, and control the forward and reverse rotation of the motor to drive the warning light to move, thereby realizing the hanging and detachment of the warning light from the power line.
[0015] 2.

DETAILED DESCRIPTION
[0018] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0019] The present invention discloses a device and method for hanging a warning light on an overhead power transmission line. Figure 1-3 As shown, it includes an equipment mounting frame 2, a lifting mechanism installed inside the equipment mounting frame 2, a warning light bracket 4 installed below the equipment mounting frame 2 through an adjustable connecting line 27, and an auxiliary positioning mechanism 3 installed directly below the equipment mounting frame 2 through a fixed connecting line 29. The installation height of the auxiliary positioning mechanism 3 is lower than the equipment mounting frame 2 but higher than the warning light bracket 4.
[0020] The mounting frame 2 is mounted under the belly of the drone. The equipment mounting frame 2 is a rectangular frame composed of an upper plate 21, a lower plate 28 and four vertical support rods, and a lifting mechanism is installed in the rectangular frame. The lifting mechanism includes a motor 26, and the motor here is a DC reduction motor. The motor 26 is mounted on the upper surface of the lower plate, and the motor 26 is connected to a gear transmission mechanism, which is a mutually meshing bevel gear, wherein the passive bevel gear 24 is sleeved on the outside of the horizontal shaft 22. The horizontal shaft 22 is rotatably mounted in the support seat 23 through a bearing. The support seat 23 is composed of two pieces, and the two support seats 23 are distributed in a left-right symmetrical manner about the center of the equipment mounting frame 2. The upper ends of the two support seats 23 are connected to the upper plate 21. The two ends of the horizontal shaft 22 protrude from the corresponding support seat 23, and each protruding part is installed with a set of wire drums 25, on which an adjustable connecting wire 27 is installed. The adjustable connecting wire 27 is made of soft, insulating material and has an adjustable length. The adjustable connecting line 27 passes through the lower plate 28 and the guide tube 33 downwards, and is connected to the guide posts 41 on the fixing plates at both ends of the warning light supporting seat 42 .
[0021] The auxiliary positioning mechanism 3 includes a positioning ring 31 with a side opening, which is a C-shaped structure and is used to clamp the power line 6 from the side. In order to enhance stability, two positioning rings 31 are provided, and the two positioning rings 31 are connected as a whole through a supporting connecting rod 32. Each positioning ring 31 is connected to the side of the lower plate 28 through a fixed connecting line 29. The fixed connecting line 29 is also made of insulating and flexible material, and the length is not adjustable. A guide tube 33 is provided on the back of the C-shaped positioning ring, which runs through the upper and lower ends. The lower end of the guide tube 33 is lower than the lower end of the positioning ring 31, and the upper end of the guide tube 33 is higher than the upper end of the positioning ring 31. A guide column 41 is provided at the upper end of the warning light bracket 4, and the diameter of the guide column is smaller than the inner diameter of the guide tube 33. The motor 26 drives the horizontal shaft 22 to rotate through gear transmission, thereby driving the adjustable connecting line 27 to rise and shorten, and the guide column 41 at the lower end of the adjustable connecting line 27 extends into the guide tube 33.
[0022] The operation steps of installing the warning light of the live hanging device of the present invention are as follows: 1) The load slot on the UAV 1 is tightly engaged with the slot on the equipment mounting frame 2, the warning light 5 is placed in the warning light supporting seat 42, and the length of the adjustable connecting wire 27 is adjusted so that the warning light wire clamp 51 is slightly lower than the lower end of the guide tube 33 of the auxiliary positioning mechanism 3.
[0023] 2) First, the drone is controlled to drive the equipment mount 2, the auxiliary positioning mechanism 3, the warning light bracket 4 and the warning light 5 to fly above the power line 6. Next, the drone is controlled to descend so that the positioning ring 31 of the auxiliary positioning mechanism 3 cooperates with the power line 6 and then the drone is controlled to rise. When the lifting force of the drone on the auxiliary positioning mechanism 3 is balanced with the gravity of the power line 6 itself, the fixed connection line 29 will be in a straight and tight state, and a relatively stable flexible connection relationship between the drone and the power line 6 is established.
[0024] 3) The motor 26 is controlled to rotate forward by means of a remote control transmitter. The motor 26 can provide a relatively low rotation speed and a relatively large torque to drive the horizontal shaft 22 and the wire drum 25 to rotate forward through the transmission gear, thereby adjusting the length of the adjustable connecting wire 27 to drive the warning light bracket 4 to move upward.
[0025] 4) When the warning light bracket 4 approaches the auxiliary positioning mechanism 3, since the outer diameter of the guide column 41 is slightly smaller than the inner diameter of the guide tube 33, the guide column 41 will be inserted into the guide tube 33, thereby controlling the moving direction of the warning light bracket 4 to guide the warning light wire clamp 51 to clamp on the power line 6.
[0026] 5) After the warning light is hung, the motor 26 is controlled to reverse, so that the warning light bracket 4 moves down, the warning light bracket 4 and the warning light 5 are separated, and then the drone is controlled to separate the device from the wire. The above process can realize the live hanging of the warning light.
[0027] Figure 4 This is a control circuit diagram of the overhead transmission line warning light live hanging device in the present invention. The switch module in the figure controls the circuit on and off, the power input module is the peripheral charging port, the battery module stores electrical energy, and the wireless remote control module receives the remote control transmitter signal to control the forward and reverse rotation of the DC reduction motor. The switch, power input, battery, and wireless remote control module are uniformly connected to the charging board.
[0028] The warning light 5 mainly includes two parts: a warning light cover and a warning light wire clamp 51. There is an external force triggering device on the warning light wire clamp 51, and the warning light wire clamp 51 can be clamped on the power line 6 after being triggered by external force. This structure and principle are prior art.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
