Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, specifically to a device for removing icing from power transmission lines. Background Technology

[0002] In the field of power transmission, transmission lines are exposed to the natural environment for extended periods and are susceptible to the effects of severe weather. Especially in winter or in cold and humid regions, ice often forms on the surface of transmission lines. Accumulated ice increases the weight of the lines, alters their mechanical and electrical properties, and poses a serious threat to the safe and stable operation of the power system. For example, excessively thick ice can lead to increased line sag, causing accidents such as line galloping, line breaks, and tower collapses, resulting in large-scale power outages and disrupting normal electricity use for social production and residents' lives. Therefore, timely and effective removal of ice from transmission lines is crucial.

[0003] Traditional manual de-icing methods require workers to climb power line towers to install mechanical de-icing equipment onto the power lines. Some equipment requires complex manual installation processes, necessitating extensive operations and adjustments on the lines. This is not only time-consuming and labor-intensive but also demands a high level of technical skill from the workers. Furthermore, installation may be hampered by factors such as the terrain and environment of the power lines, increasing the difficulty of installation. Existing mechanical de-icing equipment may also be limited in its de-icing methods, such as simply using tapping or rolling, which is insufficient for removing ice of varying thicknesses and shapes, failing to quickly and effectively complete de-icing tasks and thus failing to meet the needs of practical engineering projects. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing icing from power transmission lines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for removing icing from power transmission lines, including a mounting base, and further comprising:

[0007] The knocking and ice-crushing components for removing ice from cables are both mounted on a mounting base, which is also equipped with an adjustment component for driving the movement of the ice-crushing components.

[0008] Preferably, the two ends of the connecting shaft are rotatably connected to two connecting plates respectively, and one end of the connecting shaft passes through one of the connecting plates and extends to the outside.

[0009] Preferably, the striking assembly includes a motor fixedly installed inside the mounting base, the output end of the motor being fixedly connected to a connecting rod, and a striking rod being rotatably mounted on the connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, the mounting base is equipped with a handle on top, which can be connected to a hoisting drone. The drone can then move the device above the power line for installation, eliminating the need for manual climbing and greatly improving work efficiency. Simultaneously, it ensures operator safety and reduces the risks of working at heights. The device employs a striking component and an ice-crushing component working in tandem.

[0024] It should be noted that: the two connecting plates 2 are symmetrically fixedly installed at the bottom of the mounting base 1, forming a triangle with an open bottom, which allows for quick installation onto the line. After the mounting base 1 is installed, the pulley 4 is located at the top of the line, allowing the entire device to slide on the line. The striking component 7 and the ice-crushing component 10 are used to remove the ice from the line. The two connecting plates 2 and the various devices installed on their outer sides are calculated to maintain a balanced weight on both sides of the mounting base 1 as much as possible, so that the mounting base 1 can remain balanced on the line. After the mounting base 1 is installed on the line, the hydraulic rod 5 drives the limit ring 6 to adjust to... Figure 1 As shown, the device is limited to prevent it from tipping over and falling off the line due to strong winds or other factors.

[0025] The two ends of the connecting shaft 3 are rotatably connected to the two connecting plates 2 respectively, and one end of the connecting shaft 3 passes through one of the connecting plates 2 and extends to the outside. The connecting shaft 3 is used to connect an external drive motor to drive the connecting shaft 3 and the pulley 4 to rotate, so that the entire device can move on the line to remove ice. The top of the mounting base 1 is fixedly connected to a handle 8 to connect it to the hoisting equipment. The hoisting equipment can be a drone. By using the connecting hook on the drone to connect with the handle 8, the entire device can be moved above the line without manual installation, which not only improves work efficiency but also enhances safety.

[0026] The striking assembly 7 includes a motor 71 fixedly installed inside the mounting base 1. A connecting rod 72 is fixedly connected to the output end of the motor 71, and a striking rod 73 is rotatably installed on the connecting rod 72. The motor 71 drives the connecting rod 72 to rotate, and the connecting rod 72 drives the striking rod 73 to swing, thereby striking and breaking up the ice on the line.

[0027] The adjustment assembly 9 includes a support plate 91 fixedly mounted on the mounting base 1. A second motor 92 is fixedly mounted on the top of the support plate 91. A rotating wheel 93 is fixedly connected to the output end of the second motor 92. Two intersecting rotating rods 94 are rotatably connected to the bottom of the support plate 91. A protrusion 95 is fixedly connected to one end of each rotating rod 94. A spring 96 is fixedly connected between the two rotating rods 94. The two rotating rods 94 intersect in an X-shape and rotate relative to each other through a shaft in the middle. The rotating wheel 93 is elliptical. The ice crushing assembly 10 includes a connector fixedly connected to the rotating rods 94. Block 101, with several breaking teeth 102 fixedly installed on it; the rotating wheel 93 is driven to rotate by the motor 92, and the rotating wheel 93 contacts the protrusions 95 on the two rotating rods 94. Since the rotating wheel 93 is elliptical and a spring 96 is fixedly installed between the two rotating rods 94, the two rotating rods 94 will continuously open and close. The opening and closing of the rotating rods 94 drives the connecting block 101 and the breaking teeth 102 on its outer side to open and close, breaking the ice on the line as a whole, so that the ice falls off or breaks into pieces, which is convenient for secondary processing by the knocking component 7 and improves the de-icing efficiency.

[0028] Mounting housings 11 are fixedly installed on both connecting plates 2. A storage battery 12 is installed inside the mounting housing 11. The storage battery 12 is used to supply power to the various electrical devices mentioned above and is connected to the electrical devices through a guide. The connection is insulated.

[0029] Working Principle: It should be noted that in this solution, motor 71, motor 92, and hydraulic rod 5 are all electrically connected to the control terminal via wires. The control terminal can be mounted on the mounting base 1 and can be configured as a PLC programmable logic controller to control the aforementioned electrical equipment. Remote control operation is possible. This should be considered prior art. The specific structure, working principle, and possible control methods and spatial arrangements of these technical features can be conventionally chosen in this field. This technical solution will not elaborate further. A handle 8 is fixedly connected to the top of the mounting base 1, which can be connected to a hoisting drone. The device is moved above the line using the connecting hook on the drone, eliminating the need for manual installation and improving work efficiency and safety. Two connecting plates 2 are symmetrically fixedly installed at the bottom of the mounting base 1, forming a triangular structure with an open bottom, facilitating quick installation onto the line. After installation, the pulley 4 is located at the top of the line, allowing the device to slide on the line. By calculating the weight of the connecting plates 2 and the equipment on their outer sides, the mounting base 1 is kept as balanced as possible to ensure the device remains balanced on the line. The hydraulic rod 5 drives the limit ring 6 to adjust to a suitable state (e.g., Figure 1 As shown, the device is limited to prevent it from tipping over and falling off the line due to strong winds or other conditions. Motor 2 92 drives the rotating wheel 93 to rotate. The rotating wheel 93 contacts the protrusions 95 on the two rotating rods 94. Since the rotating wheel 93 is elliptical and a spring 96 is fixedly installed between the two rotating rods 94, the two rotating rods 94 will continuously open and close. The opening and closing of the rotating rods 94 drives the connecting block 101 and the breaking tooth 102 to open and close, breaking the ice on the line as a whole, so that the ice falls off or breaks into pieces, making it easier for the striking component 7 to perform secondary processing and improve the de-icing efficiency. Motor 1 71 drives the connecting rod 72 to rotate, and the connecting rod 72 then drives the striking rod 73 to swing, striking and breaking the ice on the line.
