[0010] In addition, after the rocket engine is started in the present scheme, the flame generated by the rocket engine is upwardly injected, and at the same time, a downward thrust is generated to the cabin cylinder, the thrust is transmitted to the power transmission cable through the hanging plate, so that the instantaneous tension generated by the rocket engine can pull the power transmission cable (i.e. the ground wire) to do instantaneous work downwardly, and the ice on the ground wire is removed.

[0011] Further, the extension nozzle and the hanging plate are detachably connected.

[0012] In this way, the extension nozzle can be conveniently installed or replaced, and the assembly is more flexible and convenient.

[0020] In the scheme, the circular arc clamping groove can adapt to the shape of the ground wire, enhance the fit between the cable and the clamping groove, and reduce the friction and wear between the cable and the clamping groove. In addition, the sliding block with the circular arc surface and the circular arc clamping groove can increase the area of mutual cooperation with the cable, so that the cable is more stable in the clamping groove during the deicing process and is not easy to slide out of the clamping groove.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0039] Example 1

[0040] like Figures 1-2 As shown, this embodiment 1 provides a self-destructing conductor de-icing device for power transmission lines, including a hook-up mechanism, a nacelle 6, and an electrical box 8. The nacelle 6 is equipped with a rocket engine 10, and the electrical box 8 is equipped with electronic components for controlling the start of the rocket engine 10.

[0041] The nacelle cylinder 6 is located between the hanging mechanism and the electrical box 8, and the hanging mechanism and the electrical box 8 are located above and below the nacelle cylinder 6 respectively and are connected to the nacelle cylinder 6; in this embodiment, a screw 13 is provided between the hanging plate 2 and the nacelle cylinder 6. One end of the screw 13 is threadedly connected to the hanging plate 2, and the other end of the screw 13 extends into the nacelle cylinder 6 and is threadedly connected to the nacelle cylinder 6. Two nuts are threadedly connected to the upper part of the screw 13, which further enhances the connection strength and connection stability of the screw 13.

[0042] like Figure 2 As shown, the hanging mechanism includes a hanging plate 2, on which a cable passage 14 is provided. The cable passage 14 extends through both sides of the hanging plate 2 (i.e., Figure 2 In this embodiment, the cable channel 14 includes a first channel 141 and a second channel 142 that are interconnected. The first channel 141 is inclined downwards, and one end of the first channel 141 is connected to the second channel 142. The other end of the first channel 141 passes through one side of the mounting plate 2 (i.e., the front and back sides). Figure 2 (on the right side of the middle), in this embodiment, the second groove 142 is a vertically arranged vertical groove structure.

[0043] In this embodiment, an extension nozzle 4 is connected to the mounting plate 2. The extension nozzle 4 is located on one side of the first groove 141 and extends downward along the inclined direction of the first groove 141. In this embodiment, the end of the extension nozzle 4 away from the mounting plate 2 is located on its lower side with a rounded arc. This can reduce friction with the power transmission cable and also guide the power transmission cable or ground wire into the first groove 141.

[0044] by Figure 2 Taking the orientation as an example, the extension nozzle 4 is connected to the upper side of the first groove 141, and the extension nozzle 4 is detachably connected to the hanging plate 2. Specifically, in this embodiment, the extension nozzle 4 and the hanging plate 2 are detachably fixedly connected by fasteners 401. In this embodiment, the fasteners 401 are hexagonal screws.

[0045] Combination Figure 3 and Figure 4 As shown, two locking rods 11 are vertically slidably connected on the hanging plate 2. One of the locking rods 11 can pass through the first groove 141, thereby making the first groove 141 closed. A handle 1 is fixedly connected between the top ends of the two locking rods 11. In this embodiment, the handle 1 is U-shaped, and the two ends of the handle 1 are connected by fixing parts 12 respectively. In this embodiment, the fixing parts 12 are also hexagonal screws. After the handle 1 is connected to the two locking rods 11, an inverted U-shaped structure is formed.

[0046] The mounting plate 2 has two vertically arranged sliding holes 16. One of the sliding holes 16 passes through the first groove 141. Two locking rods 11 are located in the two sliding holes 16 respectively and slide vertically with the sliding holes 16. Each locking rod 11 includes a thick rod and a thin rod connected coaxially. The diameter of the thick rod is larger than the diameter of the thin rod. One end of the thin rod can pass through the top of the mounting plate 2 and is fixed to the handle 1 by screws. Specifically, the top of the mounting plate 2 has a through hole communicating with the sliding hole 16. The diameter of the through hole is smaller than the diameter or width of the sliding hole 16. The thin rod can pass through the through hole, but the thick rod cannot pass through the through hole. This can prevent the entire locking rod 11 from being pulled out of the sliding hole 16 and falling off the mounting plate 2.

[0047] In this embodiment, a spring 9 is sleeved on the outside of the thin rod, and the two ends of the spring 9 abut against the top of the thick rod and the top wall of the sliding hole 16, respectively.

[0048] Combination Figure 1 , Figure 3 and Figure 4 As shown, a slider 3 is connected inside the second groove 142. A slot 301 is provided at the bottom of the slider 3. Specifically, the slider 3 is fixed to the hanging plate 2 by inserting a mandrel 15, which is threadedly connected to the hanging plate 2. The bottom of the slider 3 is an arc surface, and the slot 301 is an arc-shaped slot 301 set along the arc surface of the slider 3.

[0049] like Figure 3 As shown, in this embodiment, the bottom of the slider 3 is an arc surface, the two sides of the slider 3 are parallel vertical planes, and the top of the slider 3 is a horizontal plane. The horizontal plane at the top of the slider 3 and the vertical planes on both sides of the slider 3 are connected by a slope transition, so that the slider 3 as a whole is a block structure with the same width as its arc surface. In this embodiment, the width of the slider 3 is greater than the thickness of the hanging plate 2, which makes the arc groove 301 on the slider 3 larger and the contact area between it and the inserted power cable larger, which can further ensure the stability of the power cable during the de-icing process.

[0050] like Figure 4As shown, a plurality of mounting positions are arranged in the cabin barrel 6 in the embodiment, and the rocket engine 10 is arranged in the cabin barrel 6 in the embodiment, and the plurality of rocket engines 10 are arranged in the mounting positions in a circumferential direction, so that the single engine starting mode or the multiple engine starting mode can be realized according to the actual situation.

[0051] The rocket engine 10 is connected with a remote triggering system which can be remotely controlled and triggered, and the electronic elements related to the remote triggering system are arranged in the electric box 8. The remote triggering system mainly includes a control power supply, a signal receiving and sending device, a rocket automatic starting device and the like, and the rocket engine 10 can be started by remote control of an operator, and the single engine starting mode or the multiple engine starting mode can be selected according to the required deicing force.

[0052] The starting control signal can be sent by a remote control mode or a communication system such as a Beidou satellite, and the starting control signal can be sent by a terminal such as a mobile phone or a computer, because the remote triggering system allows the operator to remotely control the rocket engine 10 in a safe area, so that the risk of high-altitude operation in adverse weather or dangerous conditions can be avoided. The principle of the remote triggering system in the embodiment is the same as that of the remote triggering system in the utility model patent with the publication number CN119362331A, and details are not repeated here.

[0053] The rocket engine 10 in the embodiment is a small rocket engine 10, and the instantaneous impact force of the small rocket engine 10 is used to drive the iced ground wire to swing, so that the deicing effect is achieved, and the rocket engine 10 used in the embodiment can generate an impact force of 80-200 kg in 0.3 s. The principle of the rocket engine 10 is the existing technology, and the rocket engine 10 has been widely used in the field of aerospace and the like.

[0054] The specific implementation process is as follows:

[0055] The hanging mechanism in the embodiment is mainly responsible for mounting the device on the ground wire of the power transmission line by the unmanned aerial vehicle carrier, such as Figure 1 and Figure 2As shown, when the drone is attached, the drone's hook grips the top of the handle 1 on the mounting plate 2. Under the action of gravity, the spring 9 is compressed, and the locking rod 11 moves upward, thus opening the first slot 141. When the drone flies to the vicinity of the ground wire attachment point, the video device on the drone shows that the ground wire passes through the extension nozzle 4 into the first slot 141 and the second slot 142, and then slides into the slot 301 on the slider 3. At this time, the drone's hook is released from the device. The spring 9 releases its elastic force, and the locking rod 11 moves downward under the elastic force of the spring 9 and its own gravity. The opening of the extension nozzle 4 and the first slot 141 is locked again by the locking rod 11, and the installation of the device suspended on the ground wire is completed.

[0056] During the de-icing operation of the grounding conductor, the rocket engine 10 inside the remote control cabin 6 is started, and the generated flames are sprayed upward. When the rocket engine 10 explodes, it generates a downward instantaneous thrust on the cabin 6. The thrust is transmitted to the grounding conductor of the power transmission line through the hanging plate 2 and the slider 3. The instantaneous thrust is used to pull the grounding conductor, causing it to swing, thereby causing the ice on the grounding conductor to fall off.

[0057] When the device in this embodiment needs to be retrieved from the grounding wire after de-icing is completed, the drone flies to the attachment point, grabs the top of the handle 1, and lifts it upward. At this time, the locking rod 11 moves upward in sync, thereby opening the extension nozzle 4 and the opening of the first groove 141. The drone continues to rise, allowing the grounding wire to pass through the first groove 141 and the extension nozzle 4, thereby detaching the entire device from the grounding wire and completing the recovery of the entire device.

[0058] Example 2

[0059] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the rocket engine 10 in this embodiment is tilted outward from bottom to top, which can reduce the damage of the flame generated by the rocket engine 10 to the grounding wire.

[0060] Example 3

[0061] The difference between this embodiment and Embodiment 1 is that, in practice, a tension sensor is installed on the ground wire itself, such as... Figure 6 As shown, the remote triggering system in this embodiment includes a power module, an MCU control module, a 4G communication module, and a relay. The MCU control module is electrically or communicatively connected to the tension sensor, the 4G communication module, the power module, and the relay. The 4G communication module is used to receive and send signals.

[0062] The working principle of the whole remote triggering system is that the MCU control module runs, the data of the tension sensor are listened to in real time, and the tension is converted into the ice thickness according to the algorithm model in the MCU control module, the 4G communication module is communicated with the remote monitoring system, the ice thickness is transmitted in real time, and the administrator can also set the detonation ice thickness of the device.

[0063] When the ice thickness reaches the set threshold value, the MCU control module issues a control instruction, which is delivered to the relay module, the relay opens the control circuit, the rocket engine 10 is connected with the power module circuit, and the channel is greater than 0.5A current, so that the rocket engine 10 can be detonated. When multiple rocket engines 10 need to be detonated simultaneously, the remote monitoring end can be set.

[0064] The device in the utility model makes full use of the tension sensor on the conductive wire, establishes the model parameters of the tension sensor and the ice, monitors the ice thickness of the ground wire in real time, reaches the ice threshold value, the device can automatically control the rocket engine 10, drives the ground wire to swing, and achieves the purpose of adaptive control.

[0065] The device of the utility model mainly has two application scenes, one is that according to the icing condition and weather forecast in previous years, the device is installed in advance in the key icing section, the ice thickness is monitored through the tension sensor on the conductive wire, and the device is started automatically or controlled remotely to implement ice removal. This method can prevent serious icing conditions of critical line safety by starting multiple times for preventive ice removal in the early stage of ice formation; the other is that for the serious icing section that occurs suddenly, the ice removal device is laid out on site through the unmanned aerial vehicle to carry out emergency ice removal operation. Compared with the unmanned aerial vehicle carrying the ice removal rod to knock ice, the device has small operation difficulty, high ice removal efficiency and can guarantee the safety of on-site operation.

[0066] It should be noted that the above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
