Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power transmission lines, and particularly relates to an overhead power transmission line ice removal device. BACKGROUND

[0002] The power transmission line is an important part of the power system, which not only undertakes the heavy task of power transmission, but also the safety and reliability in the operation process are directly related to the stable development of national economy and the stable use of the public.

[0003] Due to the wide distribution of the power transmission line, especially in the complex terrain and harsh natural environment, the power transmission line is exposed in the wild for a long time, and the line on the power transmission tower is easy to freeze in harsh weather. After freezing, the weight of the power transmission line will increase, and in severe cases, the power transmission line will be broken, so it is necessary to use the power transmission line surface deicing device to remove the ice.

[0004] The patent with the authorized announcement number CN213547078U breaks and shears the ice layer and the sagging ice on the surface of the power transmission line through the upper cutting blade and the lower cutting blade, thereby playing the role of deicing, and without damaging the power transmission line. Since the deicing device is driven by the guide wheel, the guide wheel is arranged on the power transmission line, and when the guide wheel rotates, it can drive the power transmission line deicing device to move on the power transmission line, thereby deicing the power transmission line. However, the guide wheel adopts a fixed structure, which cannot adapt to power transmission lines of different sizes, resulting in a small contact area between the wheel groove and the power transmission line, and unable to generate enough friction, which easily causes the guide wheel to slip on the power transmission line, and it is difficult to stably push the deicing device to move on the power transmission line.

[0005] Therefore, in order to solve the above problems, it is necessary to design an overhead power transmission line ice removal device to stably move on the power transmission line. SUMMARY

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and design an ice removal device for overhead transmission lines, comprising a device body, wherein ice removal blocks and heating elements are provided on the side of the device body, and both the ice removal blocks and heating elements are in contact with the overhead transmission line. The device body is provided with a first moving element, a second moving element, an ice removal element and an ice scraping element, and the overhead transmission line is fixed between the first moving element and the second moving element. Both the ice removal element and the ice scraping element are in contact with the overhead transmission line. The device employs a combination of de-icing blocks, heating elements, and ice scraping components to remove ice from power lines. The de-icing blocks initially remove large ice blocks, preventing interference with the normal movement of the de-icing device. The reciprocating de-icing components remove ice from the power lines, while the ice scraping components remove any remaining ice after the initial impact. The heating elements evaporate any residual moisture on the power lines, preventing refreezing and improving de-icing efficiency. The guide wheels are adaptive to the size of the power lines, increasing the contact area between the guide wheel grooves and the power lines to prevent slippage. This allows the device to move stably on the power lines for subsequent de-icing operations, addressing the challenge of stable guide wheel movement on power lines in existing de-icing devices.

[0117] As Figures 1-5As shown, the present application provides an overhead power transmission line ice removal device, comprising a device main body 1, the device main body 1 adopts a square rectangular structure to cover the outside of the overhead power transmission line, wherein the weight and size structure of any two sides of the device main body 1 are basically the same, which ensures the stability of the ice removal device when moving on the overhead power transmission line.

The two cooperate to remove the ice blocks on the surface layer of the overhead power transmission line, so as to avoid affecting the normal movement of the device main body 1 on the surface of the overhead power transmission line.

[0121] In addition, the tip of the ice removal block 2 can be provided with a sawtooth shape to facilitate breaking the ice, or a heating wire is arranged on the side of the ice removal block 2 in contact with the overhead power transmission line to preliminarily ablate the ice layer, which cooperates with the device main body 1 to ensure efficient ice removal.

[0123] The first heating pipe 3-1 is fixed on the side of the first shell 1-1 through the first support rod 3-3, and the second heating pipe 3-2 is fixed on the side of the second shell 1-2 through the second support rod 3-4. The support rod can be a straight rod directly connected to the device body 1 and the first heating pipe 3-1, or an L-shaped pipe with two ends fixed on the device body 1 and the heating pipe respectively.

[0124] The device body 1 covers the outside of the overhead transmission line, and the device body 1 comprises a first shell 1-1 and a second shell 1-2, which are matched and connected by bolts. The overhead transmission line is fixed between the first shell 1-1 and the second shell 1-2. When in use, the first shell 1-1 and the second shell 1-2 are fixed on the upper and lower sides of the overhead transmission line, and then fixed by bolts.

The first moving part in the first shell 1-1 is provided with two guide wheels arranged at both ends inside the device body 1 to prevent the device body 1 from tilting during movement and ensure the stability of the device body 1 during movement.

[0129] The structures of the first guide wheel 1-1-2 and the second guide wheel 1-1-4 are consistent, which ensures the stability of the device body 1 during walking. The first guide wheel 1-1-2 comprises a support seat 1-1-2-1, a rotating shaft 1-1-2-2 and a wheel body 1-1-2-3. The rotating shaft 1-1-2-2 connects the support seat 1-1-2-1 and the wheel body 1-1-2-3. The wheel body 1-1-2-3 is sleeved outside the rotating shaft 1-1-2-2. The rotating shaft 1-1-2-2 is fixed by a fixing seat, and the wheel body 1-1-2-3 is fixed by the rotating shaft 1-1-2-2. When the device body 1 is walking, the compression resistance of the wheel body 1-1-2-3 and the rotating shaft 1-1-2-2 under pressure is ensured.

[0130] The output shaft of the first servo motor 1-1-1 is connected with the rotating shaft 1-1-2-2 of the first guide wheel 1-1-2. The rotation walking of the first guide wheel 1-1-2 is controlled by the first servo motor 1-1-1. The output shaft of the second servo motor is connected with the rotating shaft 1-1-2-2 of the second guide wheel 1-1-4. The rotation walking of the second guide wheel 1-1-4 is controlled by the second servo motor. The first servo motor 1-1-1 and the first guide wheel 1-1-2 are fixed on one side, and the second servo motor and the second guide wheel 1-1-4 are fixed on the other side.

[0131] After the first servo motor 1-1-1 and the second servo motor are started, the rotating shafts 1-1-2-2 of the first guide wheel 1-1-2 and the second guide wheel 1-1-4 can be driven to rotate, thereby driving the first guide wheel 1-1-2 and the second guide wheel 1-1-4 to rotate along the surface of the overhead transmission line.

[0132] The wheel bodies 1-1-2-3 of the first guide wheel 1-1-2 and the second guide wheel 1-1-4 are adapted to the overhead transmission line, avoiding the risks of derailment and slipping, and allowing uniform wear, prolonging the service life of the wheel bodies 1-1-2-3 and the overhead transmission line, and reducing maintenance costs.

[0133] The guide wheels involved in the prior art adopt a fixed structure and cannot adapt to transmission lines of different sizes, resulting in a small contact area between the wheel groove and the transmission line and insufficient friction, which easily leads to slipping of the guide wheel on the transmission line. Therefore, the second moving part comprises a first telescopic rod 1-2-1 and a second telescopic rod arranged in the second housing 1-2. The end of the first telescopic rod 1-2-1 is provided with a third guide wheel 1-2-3, and the end of the second telescopic rod is provided with a fourth guide wheel 1-2-4. The third guide wheel 1-2-3 and the fourth guide wheel 1-2-4 are fixed by the first telescopic rod 1-2-1 and the second telescopic rod, and the distance between the wheel body 1-1-2-3 in the first moving part and the wheel body 1-1-2-3 in the second moving part is adjusted, so as to adapt to overhead transmission lines of different sizes.

[0134] The structures of the third guide wheel 1-2-3 and the fourth guide wheel 1-2-4 are consistent with the structure of the first guide wheel 1-1-2, the wheel bodies 1-1-2-3 of the third guide wheel 1-2-3 and the fourth guide wheel 1-2-4 are adapted to the overhead transmission line, the first guide wheel 1-1-2 and the third guide wheel 1-2-3 are fixed on the outside of the overhead transmission line in cooperation, and the second guide wheel 1-1-4 and the fourth guide wheel 1-2-4 are fixed on the outside of the overhead transmission line in cooperation. The first guide wheel 1-1-2 and the third guide wheel 1-2-3 are arranged on one side in the device main body 1, and the second guide wheel 1-1-4 and the fourth guide wheel 1-2-4 are arranged on the other side in the device main body 1, so that two groups of walking members are arranged in the device main body 1, and the stability of the device main body 1 in the walking process is ensured.

[0135] Preferably, a plurality of groups of walking wheels can be arranged according to the actual situation on the site, or a corresponding group of walking wheels can be arranged between the first guide wheel 1-1-2 and the second guide wheel 1-1-4 and between the third guide wheel 1-2-3 and the fourth guide wheel 1-2-4, which is determined according to the size of the wheel body 1-1-2-3 and the length ratio of the device main body 1, and can ensure the stability of the device main body 1 in the walking process.

[0136] The outer side of the first telescopic rod 1-2-1 is provided with a first reset spring 1-2-5, and the outer side of the second telescopic rod is provided with a second reset spring 1-2-6. The first reset spring 1-2-5 is connected to the second housing 1-2 and the support seat 1-1-2-1 of the third guide wheel 1-2-3, and the first reset spring 1-2-5 is connected to the second housing 1-2 and the support seat 1-1-2-1 of the fourth guide wheel 1-2-4. The third guide wheel 1-2-3 and the fourth guide wheel 1-2-4 are fixed by the first reset spring 1-2-5, the second reset spring 1-2-6, the first telescopic rod 1-2-1 and the second telescopic rod.

[0137] When the telescopic rod is stretched, the reset spring is synchronously stretched and stores elastic potential energy. When the external force is released, the reset spring can drive the telescopic rod to automatically retract to the initial state without manual pushing back. Conversely, the same applies. In addition, the reset spring can absorb the impact force in the telescopic process of the telescopic rod, reduce the wear and deformation risk of the rod body connection, and increase the friction between the guide wheel and the outer surface of the overhead transmission line.

[0142] Through the cooperation between the first fixed plate 4-1, the second fixed plate 4-2, the first sliding rod 4-3, the second sliding rod 4-4, the deicing plate 4-5, the third servo motor 4-8, the first protrusion 4-6 and the second protrusion 4-7, the ice on the power transmission line is removed through the reciprocating knocking of the deicing plate 4-5.

[0143] In addition, the protrusion can also be connected with the first gear arranged in the first protrusion 4-6 and the second protrusion 4-7, the outer side of the first sliding rod 4-3 and the second sliding rod 4-4 is provided with a tooth corresponding to the first gear, and the length of the tooth satisfies the meshing requirement in the transmission process. The transmission process is completed through meshing.

[0144] In another embodiment,

[0145] The side of the deicing plate 4-5 contacting the overhead power transmission line is provided with deicing teeth. The teeth can concentrate stress and efficiently break hard ice layer and attached ice and snow on the overhead power transmission line, thereby improving deicing efficiency. Meanwhile, the sharp teeth can precisely act on the ice layer, reducing direct impact and wear on the body of the power transmission line, thereby protecting the insulation layer and structure of the power transmission line. In addition, the gaps between the teeth can accommodate broken ice, thereby avoiding secondary attachment of ice and snow and ensuring safe operation of the power transmission line.

[0146] In another embodiment,

[0147] The ice scraping part comprises a third telescopic rod 5-1 and a fourth telescopic rod 5-2 arranged in the first housing 1-1, and the end of the third telescopic rod 5-1 and the end of the fourth telescopic rod 5-2 are provided with an ice scraping plate 5-3 which is tightly attached to the surface of the overhead power transmission line. The position of the ice scraping plate 5-3 is controlled by the telescopic rods, so as to ensure that the ice scraping plate 5-3 is tightly attached to the overhead power transmission line and ensure the working effect of the snow removal work.

[0148] In another embodiment,

[0149] The inside of the first heating pipe 3-1 and the inside of the second heating pipe 3-2 are provided with heating wires. The heat is generated directly in the core area inside the heating pipe, reducing heat transfer loss and greatly improving heating efficiency. The heating wires are uniformly distributed in the pipe, so that the temperature of each part of the heating pipe is more balanced, avoiding local overheating or uneven heating. Meanwhile, the heating wires are wrapped inside the heating pipe, which can prevent direct contact with the overhead power transmission line and ensure that the overhead power transmission line will not be damaged during the heating process.

[0150] In another embodiment,

[0152] By arranging the return spring outside the sliding rod, the sliding rod can automatically return to the initial position by the elastic potential energy of the spring after completing the operation, without the need for manual resetting.

[0153] When the slide rod is moved downward by external force, the reset spring is compressed under the obstruction of the fixed plate, and the reset spring is elastically deformed. When the slide rod is not subjected to external force, the slide rod is returned to the initial position under the reset action of the reset spring. At the same time, the reset spring can also buffer the impact force generated during the movement of the slide rod, reduce the rigid collision of the slide rod and other components, and reduce the wear and failure probability.

[0154] In another embodiment,

[0155] The ice scraping plate 5-3 adopts an arc-shaped plate that fits the overhead transmission line. The ice and snow on the overhead transmission line are ensured to be cleaned, and the ice and snow removal effect is ensured.

[0157] The outer side of the third telescopic rod 5-1 and the outer side of the fourth telescopic tube are sleeved with the fifth reset spring 5-4. The effect of the fifth reset spring 5-4 is the same as that of the reset spring, which is to assist the corresponding telescopic rod or slide rod to complete the telescopic work. In this embodiment, the reset spring is in a compressed state, and under the reset action thereof, the ice scraping plate 5-3 tends to move in the direction of the overhead transmission line, so that the ice scraping plate 5-3 is closely fitted with the overhead transmission line, thereby scraping the residual ice on the overhead transmission line after knocking.

[0158] In another embodiment,
