Description

Technical Field

[0001] The invention relates to the technical field of deicing of overhead cables, and in particular to a blasting deicing device with a guide cylinder and a deicing method. Background Art

[0002] To address the problem of icing on cables of overhead transmission and distribution lines, current measures include manual / robot / UAV de-icing and DC ice melting. The former is essentially de-icing by blasting, and the latter is essentially high-temperature ice melting. For details, please refer to the relevant content in publication numbers CN110492422A and CN113783056A.

[0003] Manual deicing is to remove ice by knocking on the tower manually after the power outage. It is a high-altitude operation with high operation risks. Robot / drone deicing is to install the deicing robot on the ground wire by hanging it on the tower manually or hoisting it by drone. The personnel on the ground can automatically control the robot by remote control / robot to remove ice along the line. The disadvantage is that it needs to be transferred to the ice-covered line at the other end or hoisted to the ground by manual / large-load drone. The deployment is difficult and the efficiency is relatively low during the operation. The robot / drone deicing method is limited by the battery capacity and there is a risk of being stranded on the overhead line due to low power or mechanism jamming. The knocking action in the drone deicing method is to hang an insulating rope under the large-load drone, suspend the deicing stick under the rope, and control it to lift into the air so that the deicing device hits the ice-covered wire several times, causing the wire to vibrate and remove ice. This method requires a skilled drone operator to operate a heavy-load drone. It is difficult to implement on site. There may be problems such as failure to knock the drone or operating errors that cause the drone to crash. It cannot handle dense ice. Drones cannot handle ice covering live wires. There is a discharge distance limit between phases of overhead lines, and it is difficult to carry out ice knocking with heavy objects hanging below in this limited space.

[0004] In summary, considering the large size and weight of large-load UAVs and their difficulty in carrying, and the problem that the above-mentioned deicing methods all require power outages to operate, this application proposes a solution. Summary of the invention

[0017] It is further configured as follows: the guide foot support consists of a mounting plate and two guide plates, the mounting plate is used to install the hanging basket control assembly, the guide plates are symmetrically installed on the mounting plate along the width direction of the mounting plate, and the guide plates are provided with guide notches corresponding to the overhead cables.

[0018] A deicing method for a blasting deicing device with a guide cylinder, wherein the deicing operation of an overhead cable includes the following process:

[0019] On-site installation and hoisting steps: Select the installation direction of the guide plate and the blasting filler according to the thickness of the ice layer in the on-site overhead cable, install the upper clamp frame and the lower clamp frame in the guide leg support through the mounting separation unit, and hoist the guide leg support to the overhead cable through the drone equipment;

[0020] Mounting separation step: The transmission assembly is driven to rotate in a directional manner through the hanging basket control assembly and the actuator rod.

[0026] 1. The high-altitude operation method for deicing overhead cables is based on drone equipment, and the impact force generated during the blasting action is used as the basic power for blasting deicing. During the overall process, the overhead cables are independently fixed by the upper clamping frame, the lower clamping frame and the lower buffer pad, and the instantaneous impact force generated when the blasting filler is ignited is applied to the overhead cables, so that the ice covering the overhead cables is shattered and falls off. The difference from the conventional operation method is that the operation process does not require power outage processing, and the operation difficulty is relatively low;

[0027] 2. Based on the above content, the clamping process in the mounting process is further improved during the overall operation process. First, the separation action performed during the blasting action of the overall clamping process is optimized. The purpose is to avoid damage to the UAV equipment caused by the impact force generated in the blasting action. Secondly, the eccentricity between the V-groove in the lower buffer pad and the guide tube is optimized. The purpose is to change the impact direction of the blasting force. When the overhead cable is self-swayed by the impact of the blasting force, the lower clamp frame and the upper clamp frame will also perform a small rotation in a directional manner. The purpose is to ensure that the lower clamp frame and the upper clamp frame are quickly separated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0037] Embodiment 1: For the cable deicing process of overhead power transmission and distribution lines, the conventional deicing process requires power outage operation, which will affect the operation of the overall high-voltage circuit. In addition, the conventional deicing method has problems such as high operation risk, low operation efficiency and high operation difficulty. The following technical solutions are proposed:

[0038] Reference Figures 1 to 6 In this embodiment, a blasting deicing device with a guide cylinder is used in the deicing operation of an overhead cable, and includes a blasting power unit, a hoisting and mounting unit, and a mounting and separation unit. The blasting power unit is arranged on the hoisting and mounting unit, and the blasting power unit performs a blasting action on the overhead cable;

[0039] The hoisting and mounting unit is used to hoist the blasting power unit to the overhead cable and perform a clamping action on the blasting power unit and the overhead cable;

[0040] The mounting separation unit is arranged in the hoisting mounting unit, and the mounting separation unit performs the mounting separation action before the blasting action is performed.

[0041] The de-icing operation of overhead cables includes the following processes:

[0042] On-site installation and hoisting steps: select the installation direction of the guide plate and the blasting filler according to the thickness of the ice layer in the on-site overhead cable, and install the upper clamping frame 5 and the lower clamping frame 9 in the guide leg support 1 through the mounting separation unit, and hoist the guide leg support 1 to the overhead cable through the drone equipment;

[0043] Mounting separation step: The transmission assembly is driven to rotate in a directional manner through the hanging basket control assembly 7 and the actuator rod 8. When the lower roller 1102 is separated from the lower blocking plate 13, the lower clamping frame 9 is rotated in a directional manner close to the upper clamping frame 5 through the elastic action of the coil spring 6, and the overhead cable is clamped through the lower buffer pad 2;

[0044] When the blasting action is performed, the transmission assembly is driven to rotate in a directional manner again to separate the middle stop shaft 1101 from the middle stop plate 12, and the mounting separation action is completed between the guide foot support and the upper clamping frame 5 and the lower clamping frame 9;

[0045] Explosive impact step: After the mounting separation action is completed, the deflagration filler inside the guide tube 3 is ignited by the electric ignition assembly 4, and the combustion process of the deflagration filler generates an upward blasting force on the overhead cable, driving the overhead cable to perform a self-swinging action, and the following actions are included at the moment when the blasting force is generated:

[0046] Action 1: The impact direction of the blasting power is separated through the V-shaped groove, which drives the upper clamping frame 5 and the lower clamping frame 9 to deflect at an angle;

[0047] Action 2: The blasting force pushes the end cover downward, and the upper clamping frame 5 and the lower clamping frame 9 lose the elastic effect of the coil spring 6, and the upper clamping frame 5 and the lower clamping frame 9 fall off naturally from the overhead cable.

[0048] Solution description: The overall solution is aimed at the high-altitude de-icing of overhead cables. Its essence is the de-icing method of blasting. The specific solution is based on the blasting action. By limiting the blasting method, the overhead cables can be provided with blasting power. Its purpose is to drive the overhead cables to swing themselves, so that the ice on the overhead cables falls off due to the vibration. Based on this, the overhead cables are hoisted to the designated area of ​​the overhead cables through the hoisting and mounting unit. For details, please refer to the above-mentioned on-site installation and hoisting steps, mounting separation steps and blasting impact steps.

[0049] Embodiment 2: The operation process and clamping process of the blasting power unit in Embodiment 1 are described as follows:

[0050] The hoisting and mounting unit includes a guide leg support 1, an upper clamping frame 5 and a lower clamping frame 9, and the upper clamping frame 5 and one end of the lower clamping frame 9 are rotatably connected. The blasting power unit includes an electric ignition assembly 4 and a guide cylinder 3. The guide cylinder 3 is hollow inside and is provided with a deflagration filler inside, and an end cover is provided at the lower side of the guide cylinder 3. The electric ignition assembly 4 performs a remote ignition action on the guide cylinder 3, and the V-shaped groove and the center point of the guide cylinder 3 are not colinear along the axis of the vertical direction. The mounting and separation unit includes a hanging basket control assembly 7, an actuator 8, a lower block plate 13, a middle block plate 12, a connecting frame 1103, a coil spring 6 and a transmission assembly. The hanging basket control assembly 7 is installed on the guide leg support 1, and the upper end of the connecting frame 1103 is installed on the hanging basket control assembly 7, and the lower end of the connecting frame 1103 is rotatably connected to the center point of the lower block plate 13;

[0051] A pull rope 10 is connected between one end of the coil spring 6 and the end cover, the upper end of the transmission assembly is rotatably connected to the connecting frame 1103, and a middle block shaft 1101 and a lower roller 1102 are respectively arranged at the middle section and the lower section of the transmission assembly, and the setting positions of the middle block shaft 1101 and the lower roller 1102 correspond to the upper end positions of the middle block plate 12 and the lower block plate 13, respectively. One end of the actuator rod 8 is arranged at the output end position of the hanging basket control assembly 7, and the actuator rod 8 is arranged at the output end position of the hanging basket control assembly 7. One end is rotationally connected to the lower roller 1102, the middle resistance plate 12 is installed on the upper surface of the upper clamping frame 5, and the middle resistance plate 12 is set on the upper surface of the upper clamping frame 5, the lower resistance plate 13 is set on the lower surface of the lower clamping frame 9, the guide foot support 1 is composed of a mounting plate and two guide plates, the mounting plate is used to install the hanging basket control assembly 7, the guide plate is symmetrically installed on the mounting plate along the width direction of the mounting plate, and the guide plate is provided with a guide notch corresponding to the overhead cable.

[0052] The following description is based on the basic content in Example 1:

[0053] S1: During the on-site installation process, the drone only lifts the guide foot support. For this purpose, the hanging basket control assembly 7 is first installed on the installation plate, and the lower clamping frame 9 is separated from the upper clamping frame 5. In this process, the setting position of the transmission assembly is adjusted to ensure that the middle stop shaft 1101 is set at the upper end of the middle stop plate 12 and the lower roller 1102 is set on the lower stop plate 13. The purpose is to ensure that a certain angle is opened between the upper clamping frame 5 and the lower clamping frame 9, because the coil spring 6 is set on the upper clamping frame 5, and after the coil spring 6 is pulled to a certain length, the coil spring 6 has a sufficient strength of elastic potential energy, and the pull rope 10 is used to connect the coil spring 6 and the upper end cover of the guide cylinder 3. The purpose is to ensure that the upper clamping frame 5 and the lower clamping frame 9 are fully opened;

[0054] S2: Explain the contents of S1. After reaching the specified location, refer to Figure 5 , by driving the lower roller 1102 to perform directional rotation, the lower roller 1102 is slowly separated from the lower blocking plate 13. For this purpose, it is necessary to further limit the inclination angle of the lower blocking plate 13 corresponding to the side position of the lower roller 1102. After the lower roller 1102 is separated from the lower blocking plate 13, the lower clamping frame 9 loses the supporting force from the lower roller 1102, so that under the elastic action of the coil spring 6, the lower clamping frame 9 is close to the upper clamping frame 5, and the lower buffer pad 2 cooperates with the upper clamping frame 5 to complete the clamping action of the overhead cable;

[0055] S3: When performing the blasting action, the deflagration filler inside the guide tube 3 is ignited by the electric ignition assembly 4. However, in order to prevent the blasting power generated in the blasting action from affecting the drone setting, it is necessary to ensure that the transmission assembly rotates further to make the middle block shaft 1101 separate from the middle block plate 12. This can be understood as: there is no direct connection between the upper clamping frame 5, the lower clamping frame 9 and the guide leg support 1, so that the drone equipment drives the guide leg support 1 away from the upper clamping frame 5 and the lower clamping frame 9;

[0056] S4: The essence of the deflagration material in the blasting action is gunpowder material. After the deflagration material is ignited, refer to Figure 6 To explain, because the upper end of the guide cylinder 3 is closed and the lower end is provided with an end cover, the deflagration impact force generated by the combustion of the deflagration filler first pushes out the end cover. This process can be understood as: the elastic effect of the coil spring 6 is lost between the upper clamping frame 5 and the lower clamping frame 9, making it difficult to continue to maintain the action of clamping the clamping frame cable. However, it should also be explained that the deflagration impact force mainly impacts upward, so that the clamped clamping frame cable has a position to withstand the deflagration impact force and self-swings, and the vibration generated by the self-swinging action is used to remove the ice on the cable;

[0057] However, it should be noted that: because a V-shaped groove is provided in the lower cushion 2, and the center line B in the V-shaped groove and the center line A in the guide tube 3 are not on the same vertical axis, when the explosion impact force acts on the lower cushion 2, Figure 6 The eccentric direction of the center line A and the center line B in the structure will drive the lower clamp frame 9 and the upper clamp frame 5 to rotate counterclockwise when the impact force of the explosion hits the lower buffer pad 2. The purpose of this method is: on the one hand, to avoid accidental damage to the cable caused by excessive impact force of the explosion, and on the other hand, to ensure that the lower clamp frame 9 and the upper clamp frame 5 are quickly detached from the overhead cable through counterclockwise rotation.

[0058] Embodiment 3: Based on Embodiment 2, the overall lifting process is described:

[0059] Reference Figure 2 and Figure 3 To explain, the guide plate in the integral guide foot support 1 is essentially provided with two guide notches, and in the clamping process by the upper clamping frame 5 and the lower clamping frame 9, specifically, the lower clamping frame 9 is close to the upper clamping frame 5, so in the lifting process, the guide notch plays a guiding role for the overhead cable, so as to Figure 2 For example, the specific purpose is to ensure that the overhead cable is "slid into" the corresponding position of the upper clamp frame 5 along the structural shape of the guide notch. It should be noted that if the ice layer is thick, in order to ensure that the upper clamp frame 5 and the lower clamp frame 9 just clamp the overhead cable, another guide notch can be selected. The difference between the guide notches in the guide plate of the present invention lies in the difference in the inclination angle. Figure 2Take the guide gap in as an example.

[0060] In summary: improvements are made to the de-icing operation of overhead cables. Specifically, the impact force generated during the blasting action is used as the basic power for blasting de-icing, which is manifested in: optimizing the upper clamp frame and the lower clamp frame to independently fix the overhead cables, and using the instantaneous impact force generated when the blasting filler is ignited and applied to the overhead cables to make the overhead cables self-swing. The purpose is to naturally shake off the ice on them. The overall process can quickly de-ice a single overhead cable in the same section. The operation difficulty is relatively low and no power outage is required. On this basis, the eccentricity between the V-groove in the lower buffer pad and the guide cylinder is further optimized, and the overall installation method and the linkage between the lifting and mounting actions are changed in combination with the thickness of the ice layer, aiming to improve the de-icing effect and simplify the operating steps through adaptability.
