[0002] During the operation of high-voltage transmission lines, due to the influence of the natural environment, especially in cold temperate climate areas or high altitude areas, transmission lines often encounter serious icing problems. Icing can cause serious accidents such as increased weight of transmission lines, conductor dancing, and even line breakage and tower collapse, posing a great threat to the safe and stable operation of the power system. Therefore, timely and effective deicing operations are one of the important measures to ensure the safety of the power grid.

[0003] Existing deicing technologies mainly include mechanical deicing, thermal ice melting, chemical coating and electromagnetic field deicing. However, these technologies have some problems in practical applications. For example, when using mechanical hammering or heating of wires to remove ice, ice will fall directly from high altitude, which may cause damage to buildings and equipment below, or even worse, may injure pedestrians and pose a hidden danger to public safety. Therefore, we propose a high-voltage transmission line deicing device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0024] The present application provides a high-voltage transmission line deicing device, which is mainly used to solve the problem that in the prior art, when using mechanical knocking or heating of the wire to make the ice fall off, ice will fall directly from a high altitude, which may cause damage to the buildings and equipment below, or even more seriously, may injure pedestrians and bring hidden dangers to public safety, and provides the following technical solutions, which will be combined with Figure 1-Figure 3 Make a detailed description:

[0025] A deicing device for a high-voltage power transmission line comprises: a hopper 1 for receiving crushed ice;

[0026] An ice-breaking mechanism 2 is arranged on the upper side of the hopper 1 and is used for breaking ice cubes;

[0027] An operating rod 3 is arranged at the bottom of the hopper 1, and the length of the operating rod 3 is adjustable;

[0028] The connecting seat 4 is arranged between the bottom of the hopper 1 and the operating rod 3 , and the connecting seat 4 is used to adjust the angle of the hopper 1 .

[0029] The working process of the device is described as follows:

[0030] In the first step, the operator carries the high-voltage transmission line deicing device of the present invention to the bottom of the tower that needs deicing or to an appropriate position, and ensures that the hopper 1 is in the correct ice receiving position;

[0031] In the second step, the operator holds the operating lever 3 and controls the ice-breaking mechanism 2 to knock the ice-covered wire to break and fall off the ice. With the action of the ice-breaking mechanism 2, the broken ice will fall into the hopper 1;

[0032] In the third step, after the de-icing operation is completed, the operator safely moves the crushed ice in the hopper 1 to a designated location for melting or processing. After emptying the hopper 1, the de-icing device should be cleaned and maintained as necessary in preparation for the next use.

[0033] The de-icing device for high-voltage transmission lines uses the physical and mechanical action of the ice-breaking mechanism 2 on the ice-covered conductor to cause the ice to crack and fall off. At the same time, a hopper 1 for receiving crushed ice is provided to receive the ice removed from the conductor, thereby reducing the safety hazard caused by the direct fall of ice and protecting the safety of the buildings, equipment and pedestrians below.

[0034] like Figure 3 As shown, in some embodiments, the hopper 1 is a transparent plastic hopper 1, and the diameter gradually decreases from the upper end to the bottom. More specifically, the transparent plastic hopper 1 allows the operator to intuitively monitor the collection of ice cubes and timely understand the amount of ice cubes in the hopper 1 to avoid overflow or overload. The diameter is larger at the top and smaller at the bottom to better receive the falling crushed ice and prevent it from falling from the upper end of the hopper 1.

[0035] like Figure 3 As shown, in some embodiments, the ice-breaking mechanism 2 includes a first ice-breaking rod 201 fixedly arranged on the inner wall of one side of the hopper 1 at intervals, the first ice-breaking rod 201 is used to break ice on the top of the transmission line, and a second ice-breaking rod 202 is fixedly arranged between the middle of the inner wall of the hopper 1, and the second ice-breaking rod 202 is used to break ice on the bottom of the transmission line. The first ice-breaking rod 201 is hook-shaped, and the second ice-breaking rod 202 is M-shaped. Spherical protrusions 203 are evenly distributed on the surfaces of the first ice-breaking rod 201 and the second ice-breaking rod 202. More specifically, when the de-icing operation begins, the operator uses the handheld operating rod 3 to control the ice-breaking mechanism 2. Due to the special design of the ice-breaking rod, When external force acts on the ice-breaking mechanism 2 through the operating rod 3, the first ice-breaking rod 201 and the second ice-breaking rod 202 respectively hit the ice on the top and bottom of the transmission line. The hook design of the first ice-breaking rod 201 cooperates with the M-shaped middle groove design on the top of the second ice-breaking rod 202. When in use, the wire is inserted into the inner circle of the first ice-breaking rod 201 and is limited by the second ice-breaking rod 202 to prevent it from being separated from the wire during the up and down knocking process. The spherical protrusion 203 enters the ice during the ice-breaking process and breaks the ice through physical pressure, thereby increasing the grip and destructive power of the ice-breaking mechanism 2 on the ice surface, thereby improving the de-icing efficiency.

[0036] like Figure 2 As shown, in some embodiments, the operating rod 3 includes a connecting tube 301, and extension rods 302 are threadedly connected at two ends of the connecting tube 301, and one of the extension rods 302 is connected to the connecting seat 4. More specifically, the operating rod 3 includes a connecting tube 301, which serves as the main body of the operating rod 3 and is used to stabilize and support the structure of the entire operating rod 3. When in use, the total length of the operating rod 3 can be changed by rotating the connecting tube 301 and adjusting the length of the extension rod 302 protruding from the connecting tube 301 to adapt to de-icing operations at different heights and distances.

[0037] like Figure 2 As shown, in some embodiments, the extension rod 302 and the connecting tube 301 are both insulating plastic parts, and a rubber sleeve 303 is provided on the end of one of the extension rods 302. More specifically, the use of insulating plastic parts can effectively isolate the current and reduce the risk of electric shock caused by accidental contact with live parts during de-icing operations, thereby improving the safety of the operation.

[0038] like Figure 2As shown, in some embodiments, the connecting seat 4 includes a mounting block 401 fixed to the bottom of the hopper 1, and a ball groove 4011 is constructed at the bottom of the mounting block 401. A ball block 402 is slidably embedded in the ball groove 4011. One end of the operating rod 3 is connected to the ball block 402, and a locking bolt 403 is threadedly connected to one side of the mounting block 401. More specifically, the ball block 402 is slidably embedded in the ball groove 4011. This design allows the ball block 402 to rotate or slide freely within a certain range in the ball groove 4011, thereby providing multiple degrees of freedom, so that the operating rod 3 can be flexibly operated at different angles. When the operating rod 3 is adjusted to an appropriate position and angle, the position of the ball block 402 can be fixed by tightening the locking bolt 403, thereby ensuring the stability of the operating rod 3 during operation and the accurate control of the ice-breaking mechanism 2. When the operating rod 3 is adjusted to an appropriate position and angle, the position of the ball block 402 can be fixed by tightening the locking bolt 403, thereby ensuring the stability of the operating rod 3 during operation and the accurate control of the ice-breaking mechanism 2.
