Description

Technical Field

[0001] This utility model relates to the field of blasting de-icing technology, specifically to a guide cylinder structure that uses blasting de-icing. Background Technology

[0002] The principle of vibration de-icing for overhead cables is explained, including methods such as drone knocking or blasting de-icing. The principle of blasting de-icing is explained by using drone equipment to fix a blasting structure at the overhead cable. The impact force generated by the blasting action causes the cable to vibrate, thereby achieving the de-icing effect.

[0003] It should be noted that the impact force in the blasting action is only released momentarily. If the release force is insufficient, it will be difficult to make the cable swing and achieve the effect of vibration de-icing. However, if the release force is large, the instantaneous impact force will directly act on the cable, which may cause irreversible damage to the cable. Furthermore, it is necessary to ensure that the blasting structure and the cable are "fixed" during the release of the blasting impact force, which makes the recovery of the blasting structure relatively difficult. This utility model proposes a solution to this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a guide cylinder structure that adopts the blasting de-icing method. For blasting de-icing operations, the main reliance is on the instantaneous release of blasting impact force. The blasting impact force affects the vibration de-icing effect and can also cause irreversible damage to overhead cables. Furthermore, the recovery of the blasting structure in the later stage is relatively difficult.

[0005] The purpose of this utility model can be achieved through the following technical solution: a guide tube structure using blasting de-icing method, applied in overhead cable blasting de-icing operations, including a clamping component and a blasting component, wherein the clamping component consists of an upper clamping frame and a lower clamping frame, and the blasting component includes an electric ignition structure and a blasting guide tube;

[0006] The blasting guide tube is installed at one end of the lower clamping frame, and the lower end of the blasting guide tube is open. The blasting guide tube is filled with deflagration filler. The electric ignition structure is provided with an ignition structure corresponding to the deflagration filler. A lower buffer protective pad is installed at the position of the lower clamping frame corresponding to the blasting component. A V-shaped groove is opened on the lower buffer protective pad.

[0007] The configuration is further defined as follows: a coil spring assembly is provided on the upper clamping frame, and a self-breaking component is provided between the coil spring assembly and the blasting guide cylinder. The self-breaking component includes a pull rope, an end cap, and a self-destructing ignition plate. The end cap is located on the lower side of the blasting guide cylinder, and a protrusion is provided on the lower side of the blasting guide cylinder. The self-destructing ignition plate is located on the protrusion, and the pull rope is connected to one end of the protrusion located on the coil spring assembly.

[0008] The upper and lower clamping frames are further configured such that the other ends of the upper and lower clamping frames are rotatably connected.

[0009] The configuration is further defined as follows: the upper end of the blasting guide cylinder is closed, and the upper end of the blasting guide cylinder is in contact with the lower buffer protective pad.

[0010] Further configuration: the midpoint of the bottom end of the V-groove and the center point of the overhead cable are on the same vertical axis, and the axis of the center point of the blasting guide cylinder along the vertical direction is offset from the axis of the midpoint of the bottom end of the V-groove along the vertical direction.

[0011] This utility model has the following beneficial effects:

[0012] The de-icing operation for overhead cables, based on the explosive impact force generated during the blasting action, essentially involves using an upper and lower clamping frame to hold and support the overhead cable. The key is the use of a high-strength explosive guide cylinder as a foundation. The impact force released instantaneously during the combustion of the deflagration filler serves as the driving force for the vibration de-icing of the overhead cable. A lower buffer protective pad acts as the initial protective structure for the overhead cable. Specifically, a V-shaped groove is optimized and improved within the lower buffer protective pad to fully clamp the overhead cable. The crucial aspect lies in the staggered clamping position between the explosive guide cylinder and the overhead cable. This position serves two purposes: firstly, to prevent direct damage to the overhead cable from the explosive impact force, and secondly, to facilitate the separation process between the explosive guide cylinder and the overhead cable, thereby improving de-icing efficiency.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1: For blasting de-icing operations, since they mainly rely on the instantaneous release of blasting impact force, the blasting impact force affects the vibration de-icing effect and can also cause irreversible damage to overhead cables. Furthermore, the subsequent recovery of the blasted structure is relatively difficult. The following technical solution is proposed to address these issues:

[0022] Reference Figures 1-5 In this embodiment, a guide tube structure using blasting de-icing method is applied in overhead cable blasting de-icing operations. It includes a clamping component and a blasting component. The clamping component consists of an upper clamping frame 1 and a lower clamping frame 2. The blasting component includes an electric ignition structure 4 and a blasting guide tube 5.

[0023] The blasting guide tube 5 is installed at one end of the lower clamping frame 2, and the lower end of the blasting guide tube 5 is open. The blasting guide tube 5 is filled with deflagration filler, and the electric ignition structure 4 is equipped with an ignition structure corresponding to the deflagration filler. A lower buffer protective pad 3 is installed on the lower clamping frame 2 at the position corresponding to the blasting component. The lower buffer protective pad 3 has a V-shaped groove. A coil spring assembly 6 is installed on the upper clamping frame 1. A self-destructing component is installed between the coil spring assembly 6 and the blasting guide tube 5. The self-destructing component includes a pull rope 8, an end cap 7, and a self-destructing ignition plate. The end cap 7 is located on the lower side of the blasting guide tube 5. The blasting guide cylinder 5 has a raised section on its lower side, and a self-destruct ignition plate is located on the raised section. The pull rope 8 is connected to one end of the raised section located on the coil spring assembly 6. The upper clamping frame 1 and the lower clamping frame 2 are rotatably connected at their other ends. The upper end of the blasting guide cylinder 5 is closed, and the upper end of the blasting guide cylinder 5 is in contact with the lower buffer protective pad 3. The midpoint of the bottom end of the V-groove and the center point of the overhead cable are on the same vertical axis. The vertical axis of the center point of the blasting guide cylinder 5 is offset from the vertical axis of the midpoint of the bottom end of the V-groove.

[0024] Solution Description: Based on Figure 1The coil spring assembly 6 is used as an elastic element. The elasticity of the coil spring assembly 6 brings the upper clamping frame 1 and the lower clamping frame 2 closer together, ensuring that the local position of the overhead cable is clamped and fixed on the V-shaped groove in the lower buffer protective pad 3. The specific structure between the upper clamping frame 1 and the lower clamping frame 2 is not described in this embodiment.

[0025] Specific reference Figure 3 and Figure 4 To explain, during the operation, after the entire blasting assembly is fully mounted on the overhead cable, because the blasting guide cylinder 5 is filled with deflagration filler, and although its lower end is open, it is temporarily sealed by the end cap, and a pull rope 8 is provided between the end cap and the coil spring assembly 6. The purpose of the pull rope 8 is to temporarily act as a "temporary locking structure" for the upper clamping frame 1 and the lower clamping frame 3 to cooperate with the elastic action of the coil spring assembly 6.

[0026] Therefore, during the blasting operation, the electric ignition structure 4 is used for remote ignition, which causes the deflagration packing inside the blasting guide tube 5 to be ignited quickly and release a large amount of gas. For this, it is necessary to ensure that the material of the blasting guide tube 5 has the characteristic of high strength. Only by ensuring that a large amount of gas is released from its lower side during combustion will an upward impact force be generated on the lower buffer protection pad 3. In this process, the end cap 7 is blown open. It can be understood that the "temporary locking structure" between the upper clamping frame 1 and the lower clamping frame 3 is lost and is naturally released based on the blasting impact force. It should also be noted that the pull rope 8 is not connected to the end cap 7, but is fitted on the protrusion below the blasting guide tube 5. There is a self-destructing ignition plate on the inner side of the protrusion below the blasting guide tube 5. When the deflagration filler fails to ignite, the entire deflagration assembly needs to detach from the cable and fall for easy recovery. When a failure occurs, the self-destruct ignition plate can be heated remotely to melt the pull rope 8, causing the coil spring group 6 to lose its reset stress, the device to lose its clamping force, and the clamping force to be released and fall freely. The entire structure in this utility model naturally detaches from the overhead cable, eliminating the need for personnel to carry out fixed-point recovery and eliminating its own impact on the overhead line.

[0027] The key points to note regarding the above are: the vertical axis of the center point of the blasting guide cylinder 5 is offset from the vertical axis of the midpoint of the bottom of the V-groove; the center point of the blasting guide cylinder 5 is misaligned with the center point of the overhead cable. Specifically... Figure 4For example, because the blasting guide cylinder 5 is positioned to the right relative to the overhead cable, the blasting impact force generated by the blasting action will also be applied to the overhead cable during this process. However, it is not a "complete impact." The purpose is to ensure that the impact force is large enough to damage the overhead cable. However, the blasting impact force will still act on the overhead cable and cause vibration. The key is that because the overall lower buffer protective pad 3 is asymmetrical about the impact force direction of the blasting guide cylinder 5, the overall structure rotates counterclockwise based on the center point of the overhead cable. Conversely, if the blasting guide cylinder 5 is positioned to the left relative to the overhead cable, it rotates clockwise. This aims to ensure that the blasting impact force is released to achieve the de-icing effect, and to cause the overall blasting component to fall off naturally by driving the directional rotation of the upper clamping frame 1 and the lower clamping frame 2.

[0028] In summary: Based on a high-strength blasting guide cylinder, the impact force released instantaneously during the combustion of the deflagration filler is used as the driving force for vibration de-icing of overhead cables. The lower buffer protective pad serves as the initial protective structure for the overhead cables. Specifically, a V-shaped groove is optimized and improved in the lower buffer protective pad to fully clamp the overhead cables. The key lies in the staggered clamping position between the blasting guide cylinder and the overhead cables. On the one hand, this avoids direct damage to the overhead cables from the blasting impact force, and on the other hand, it facilitates the separation process between the blasting guide cylinder and the overhead cables, thereby improving de-icing efficiency.
