Description

Technical Field

[0001] The present invention relates to the technical field of power equipment maintenance, and particularly to a snow removal device for power transmission lines. Background Art

[0002] In cold regions or winter, snow easily accumulates on power transmission lines. The accumulated snow increases the weight of the transmission lines, causing the lines to sag and dance, and even leading to accidents such as line breakage and tripping, seriously affecting the safe and stable operation of the power system. Traditional methods for removing snow from transmission lines mainly include manual snow removal and some simple mechanical snow removal tools. Manual snow removal is inefficient and poses safety risks. Operators need to climb poles or use insulated poles to operate on the ground, with high labor intensity and difficulty in dealing with large areas of snow accumulation.

[0003] In the prior art, such as the "snow removal device for power maintenance" with the patent application number: CN202122297272.0, it includes a base. A support frame is fixedly installed at the top of the base and in the middle position. An upper support wheel is rotatably installed on the inner wall of the support frame through a bearing. For this snow removal device for power maintenance, the left support wheel drives the transmission gear to rotate. The snow attached to the surface is cleared by the contact between the tooth heads on the surface of the transmission gear and the surface of the transmission line. The transmission gear drives the rotating shaft to rotate. The rubber cleaning strip sleeved outside the rotating shaft contacts the surface of the transmission line to clean the snow. At the same time, the snow removal strip also rotates. The snow removal strip rotates while sticking to the outside of the transmission line to clean the snow and ice slag on the surface of the transmission line. By pressing the transmission lines on both sides of the small motor downward to bend the wires, the connection stability is improved. At the same time, bending the wires can break the ice on the wire surface, thereby improving the cleaning effect.

[0004] Existing snow removal devices for transmission lines are prone to damage to the power grid lines during use due to their single structural design, and are not convenient for adjusting and using according to the height of the power transmission lines, resulting in poor use effects. In view of the above problems, a snow removal device for power transmission lines is proposed. Summary of the Invention

It is beneficial to heat and remove snow from the power line by the high-temperature hot air when the snow removal mechanism 1 is close to the cable line, avoiding the problem of damage to the cable line caused by scraping or cutting operations. The air inlet 106 can provide the function of air inlet, facilitating the formation of air circulation inside and ensuring the snow removal effect. The mounting seat 201 provides installation support. The steering motor 202 is arranged on the top of the mounting seat 201, facilitating the installation support for the support rod 203 and realizing the rotation function.

[0025] In this embodiment, during the snow removal process, rough ground is easily encountered. If stable support is not provided for this type of ground, the equipment is likely to tip over during snow removal. Therefore, during the snow removal process, the extension member 403 is rotated and unfolded by the side support block 401 in cooperation with the connecting member 402, and then effective angle adjustment is provided through the telescopic cooperation of the first hydraulic telescopic rod 404 and the second hydraulic telescopic rod 405, facilitating the unfolding of the side support leg 406, so that the support pad 407 stably supports on the ground, thereby being beneficial to providing a stable operation function when operating on rough ground.

[0026] Embodiment 3: As Figure 8 shown, the moving mechanism 5 includes a bottom support frame 501. Side support frames 502 are provided on both sides of the bottom support frame 501. Driving wheels 503 are movably installed at both ends of the side support frames 502. A crawler wheel 504 is wound and connected to the outside of the driving wheel 503. The crawler wheels 504 are arranged on both sides of the bottom support frame 501.

[0027] In this embodiment, the bottom support frame 501 cooperates with the side support frames 502 to provide connection and installation for the driving wheels 503 and achieve driving rotation, thereby being beneficial to driving the crawler wheels 504 to achieve the transmission function, effectively improving the cleaning effect, further being beneficial to achieving the function of high-efficiency movement, thus ensuring the snow removal efficiency, realizing the function of large-scale snow removal, and ensuring the safety of the operator. The crawler has a large contact area with the snow, which can effectively disperse the weight of the equipment, and its special pattern design can increase the friction between the crawler and the snow, so as to drive smoothly in areas with deep snow. The crawler-type moving device has strong obstacle-crossing ability. It can adjust the movement posture of the crawler, such as lifting the front end of the crawler to cross small obstacles, or using the flexibility of the crawler to fit the shape of larger obstacles and climb through. When climbing slopes or crossing uneven sections close to power transmission lines, the crawler can automatically adjust the fit with the ground and the driving posture according to the terrain, so that the snow removal mechanism of the snow removal device can always be kept within a suitable operating height range, facilitating snow removal operations on power transmission lines at different heights, reducing the need for frequent adjustment of the device or additional auxiliary operations due to height adaptation problems, and improving the continuity and smoothness of the snow removal operation.

[0028] In the present invention, when the snow removal device for the power transmission line is in use, first, the side support block 401 cooperates with the connecting member 402 to rotate and unfold the extension member 403, and then the first hydraulic telescopic rod 404 and the second hydraulic telescopic rod 405 cooperate with each other to extend and retract to provide effective angle adjustment, facilitating the unfolding of the side support leg 406, so that the support pad 407 stably supports on the ground. Furthermore, it is beneficial to provide a stable operation function during operation in the case of rough ground. The mounting seat 201 provides mounting support, and the steering motor 202 is arranged on the top of the mounting seat 201, which facilitates providing mounting support for the support rod 203 and realizing the rotation function. Through the telescopic control of the pneumatic telescopic rod 204, it is convenient to make the adjusting rod 205 realize the functions of angle and height adjustment.

The lifting platform 301 on the lifting mechanism 3 is connected to the mounting seat 201 and supported by the lifting folding frame 302 at the bottom. At the same time, it cooperates with the motor 308 on the base 303 to drive the lead screw 306 to rotate, and then the sliding member 304 cooperates with the connecting shaft to slide and adjust inside the chute 305, which is beneficial to control the lifting folding frame 302 to realize the lifting adjustment function, and thus can be quickly adjusted according to the requirements of the operation height, effectively expanding the operation range and ensuring the snow removal effect. The heating wires 105 are distributed inside the heating frame 101, and the heating wires 105 are heated by electric control. At the same time, the fan 103 drives the fan blade 104 to rotate, and then it is convenient to discharge the heat generated by the heating of the heating wires 105 from the ventilation slot 102 through the fan blade 104. It is beneficial to heat and remove snow from the power line by high-temperature hot air with the snow removal mechanism 1 approaching the cable line, avoiding the problem of damage to the cable line caused by scraping or cutting operations. The air inlet 106 can provide the function of air intake, facilitating the internal air to circulate and ensuring the snow removal effect.
