[0002] With the development of society, electric energy has become one of the indispensable energy sources in people's daily life, providing a strong guarantee for people's high-quality life. As a common outdoor transmission line, high-voltage lines are likely to form ice outside the high-voltage lines in the cold winter when it rains or snows. Line icing is a serious natural disaster for the power supply system. Icing can cause the line towers to collapse or break due to the pressure they cannot withstand. In severe cases, it can cause the entire power grid to be paralyzed and cause power outages. Severe icing can make the towers unable to support the weight and collapse.

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0024] Example:

[0025] like Figure 1-Figure 4 As shown, this embodiment provides a high-voltage line deicing device, including an inverted U-shaped mounting seat 1, in which two vertical movable plates 2 parallel to each other are arranged, and the inverted U-shaped mounting seat 1 is also equipped with a first driving mechanism for driving the two vertical movable plates 2 to move toward or away from each other. Before installation, the two vertical movable plates 2 are respectively located on both sides of the high-voltage line 3. When the high-voltage line deicing device is set on the high-voltage line 3, the two vertical movable plates 2 are brought closer together to realize the installation of the high-voltage line deicing device on the high-voltage line 3.

[0026] Specifically, the two vertical movable plates 2 are rotatably connected to one side close to each other with multiple driving wheels 4 that cooperate to clamp the high-voltage line 3. In practice, when the high-voltage line deicing device is installed, the driving wheels 4 are arranged on both sides of the high-voltage line 3. When the two vertical movable plates 2 are controlled to move in the direction close to each other, all the driving wheels 4 can cooperate to clamp the high-voltage line 3 to ensure the overall stability. At the same time, the driving wheels 4 can also roll along the high-voltage line 3 when rotating, thereby driving the entire high-voltage line deicing device to move on the high-voltage line 3, so that the high-voltage line deicing device can de-ice along the high-voltage line 3. A second driving mechanism for driving all the driving wheels 4 to roll on both sides of the high-voltage line 3 is installed on the inverted U-shaped mounting seat 1. When all the driving wheels 4 clamp the high-voltage line 3, they can realize transmission connection with the second driving mechanism, and then rotate under the control of the second driving mechanism to realize the entire movement.

[0027] During the entire movement process, the surface of the high-voltage line 3 needs to be de-iced, and the de-icing structure is as follows:

[0028] Semicircular deicing plates 5 are fixed on one side of the two vertical movable plates 2 close to each other to ensure the stability of the semicircular deicing plates 5. The two semicircular deicing plates 5 cooperate to form a first deicing ring that is sleeved outside the high-voltage line 3. The inner diameter of the first deicing ring is larger than the diameter of the high-voltage line 3, so as to remove a layer of ice outside the high-voltage line 3; the two vertical movable plates 2 are rotatably connected to one side of the two vertical movable plates 2 close to each other, and a second deicing ring is formed between the two deicing wheels 6. The inner diameter of the second deicing ring is smaller than the inner diameter of the first deicing ring. In practice, preliminary deicing can be performed by the first deicing ring first, and then secondary deicing can be performed by the second deicing ring, so as to remove most of the accumulated ice outside the high-voltage line 3. A third driving mechanism for driving the two deicing wheels 6 to rotate is installed on the inverted U-shaped mounting seat 1. The deicing wheels 6 rotate to de-ice during deicing, which can make its deicing effect better.

[0029] When installing the present invention, the whole is first set above the high-voltage line 3, and then the high-voltage line deicing device moves downward so that the high-voltage line 3 is located between all the driving wheels 4. At this time, the first driving mechanism can be turned on to move the two vertical movable plates 2 in a direction close to each other, so that all the driving wheels 4 cooperate to clamp the high-voltage line 3 to ensure the stability of the whole on the high-voltage line 3. The first deicing ring and the second deicing ring are also sleeved outside the high-voltage line 3. At this time, the second driving device can be turned on to make all the driving wheels 4 start to rotate, and then the friction between the driving wheels 4 and the high-voltage line 3 drives the entire high-voltage line deicing device to slide along the high-voltage line 3. At this time, the first deicing ring performs the first deicing on the ice layer on the high-voltage line 3, and then the second deicing ring performs the second deicing. Most of the ice outside the high-voltage line 3 is removed by two deicings, thereby reducing or even avoiding the harm of ice accumulation to the high-voltage line 3, and ensuring the stability of the power grid operation. Moreover, the high-voltage line deicing device does not require workers to perform continuous operation during actual operation, which reduces labor intensity and improves the safety of operators.

[0030] It should be noted that, when installing the high-voltage line deicing device, the installation position can be adjusted according to the actual situation, so that the first deicing ring and the second deicing ring can better de-ice. It should be further noted that in practice, there is no specific restriction on whether the drive wheel 4 is located in the middle of the whole or at one end, and it can be adjusted according to the actual situation.

[0031] As a preferred technical solution in the present invention, the first driving mechanism includes a driving rod 7, a limiting rod 8 and a first motor 9. The driving rod 7 is two threaded rod sections with opposite thread directions at both ends. The two threaded rod sections are respectively threadedly connected to the two vertical movable plates 2. One end of the driving rod 7 is rotatably connected to one side of the inverted U-shaped mounting seat 1, and the other end of the driving rod 7 passes through the other side of the inverted U-shaped mounting seat 1 and is connected to the motor shaft of the first motor 9. The first motor 9 is installed on the outer wall of the other side of the inverted U-shaped mounting seat 1. In practice, the first motor 9 can drive the driving rod 7 to rotate, and when the driving rod 7 rotates, the two vertical movable plates 2 can be driven to move in the direction of approaching or moving away from each other; the limiting rod 8 is a smooth round rod, and the two ends of the limiting rod 8 respectively penetrate the two vertical movable plates 2 and are fixedly connected to the two sides of the inverted U-shaped mounting seat 1 to ensure the stability of the limiting rod 8. In this way, when the driving rod 7 drives the two vertical movable plates 2 to move, the limiting rod 8 can be used to ensure that the two vertical movable plates 2 are stably sliding when moving.

[0032] As a preferred technical solution in the present invention, a first nut 10 is fixed on one side of the two vertical movable plates 2 close to each other, and the two threaded rod sections of the driving rod 7 are respectively threadedly connected to the two first nuts 10, so that the driving rod 7 is more stable when driving the two vertical movable plates 2 to move; one end of the driving rod 7 is rotatably connected to one side of the inverted U-shaped mounting seat 1 through a ball bearing to ensure its flexibility; the two vertical movable plates 2 are slidably connected to the limit rod 8 through a linear bearing to ensure that the friction of the two vertical movable plates 2 is smaller when sliding relative to the limit rod 8.

[0033] As a preferred technical solution in the present invention, two vertical movable plates 2 are rotatably connected to one another on one side thereof and close to each other. Each driving wheel 4 is provided with an arc-shaped inner groove arranged in a ring shape. The high-voltage line 3 is clamped between the arc-shaped inner grooves of the driving wheels 4 on both sides thereof. Therefore, when the driving wheels 4 rotate, the high-voltage line 3 is always restricted in the arc-shaped inner grooves thereof, thereby ensuring the stable movement of the whole on the high-voltage line 3. Two first horizontal mounting plates 11 are installed on one side thereof and close to each other. Both ends of the central axis of the driving wheel 4 are rotatably connected to the corresponding two first horizontal mounting plates 11 through ball bearings, thereby ensuring the stability and flexibility of the driving wheel 4.

[0034] As a preferred technical solution in the present invention, the second driving mechanism includes a first gear 12, a second gear 13, a third gear 14 and a second motor 15. The upper ends of the central axes of the four driving wheels 4 are each equipped with a third gear 14 located above the first horizontal mounting plate 11. The first gear 12 is respectively meshed with two third gears 14 corresponding to a vertical movable plate 2, and the second gear 13 is respectively meshed with two third gears 14 corresponding to another vertical movable plate 2. The second motor 15 is installed at the upper end of the inverted U-shaped mounting seat 1 and is connected to the central axis of the first gear 12. The second gear 13 is rotatably connected to the inverted U-shaped mounting seat 1. In practice, the second motor 15 can drive the first gear 12 to rotate after being started, and then cooperate with the second gear 13 to drive all the third gears 14 to rotate. For example, the second motor 15 drives the first gear 12 to rotate forward, and the rotation directions of the second gear 13 and the four third gears 14 are as follows: Figure 4 As shown, the rotation of the four third gears 14 on both sides of the high-voltage line 3 enables all the driving wheels 4 to drive the high-voltage line de-icing device as a whole to move in the same direction, thereby ensuring the stability of the high-voltage line de-icing device during movement, and through the forward or reverse rotation of the motor, the high-voltage line de-icing device can be moved back and forth on the high-voltage line 3.

[0035] As a preferred technical solution in the present invention, the number of teeth of the first gear 12 is equal to the number of teeth of the second gear 13, and the number of teeth of the first gear 12 is less than the number of teeth of the third gear 14, and the central axis of the third gear 14 is rotatably connected to the inner top surface of the inverted U-shaped mounting seat 1 through a ball bearing; a reduction box 16 is installed on the upper end of the inverted U-shaped mounting seat 1, and the second motor 15 is connected to the central axis of the first gear 12 through the reduction box 16. The rotation speed of the second motor 15 is adjusted by changing the number of teeth of the first gear 12, the second gear 13 and the third gear 14, and the cooperation of the reduction box 16, so that the overall sliding is relatively slow when the high-voltage line 3 is spread, thereby ensuring the stability of the overall sliding and the deicing effect during sliding.

[0036] As a preferred technical solution in the present invention, the outer wall of the first de-icing ring is a conical structure, and the outer diameter of the first de-icing ring gradually decreases from one end away from the de-icing wheel 6 to the other end, so that the ice can be shoveled to the outside; the de-icing wheel 6 includes a vertical center rod and a plurality of de-icing pieces evenly distributed outside the vertical center rod, each de-icing piece has a semicircular groove in the middle, and the semicircular grooves of the two de-icing wheels 6 cooperate to form the second de-icing ring; two second horizontal mounting plates 17 are installed on one side of the two vertical movable plates 2 close to each other, and the two ends of the vertical center rods of the two de-icing wheels 6 are rotatably connected to the corresponding two second horizontal mounting plates 17 through ball bearings, so that the de-icing wheel 6 de-ices in a rotating manner, which can reduce its resistance during de-icing and make the overall movement easier.

[0037] As a preferred technical solution in the present invention, the third driving mechanism includes a first bevel gear 18, a second bevel gear 19 and a third motor 20. The upper ends of the vertical center rods of the two deicing wheels 6 are both installed with second bevel gears 19 located above the second horizontal mounting plate 17. The first bevel gear 18 is installed between the two second bevel gears 19, and the lower ends of both sides of the first bevel gear 18 are respectively meshed with the two second bevel gears 19; the central axis of the first bevel gear 18 passes through the two vertical movable plates 2, and one end of the first bevel gear 18 is connected to the inverted U-shaped mounting plate 17 through a ball bearing. One side of the seat 1 is rotatably connected, and the other side of the first bevel gear 18 is connected to the motor shaft of the third motor 20. The third motor 20 is installed on the outer wall of the other side of the inverted U-shaped mounting seat 1. In practice, the position of the first bevel gear 18 will not change. When the driving wheel 4 cooperates to clamp the high-voltage line 3, the second bevel gear 19 also happens to mesh with the first bevel gear 18. Then, by starting the third motor 20, the first bevel gear 18 can be driven to rotate by the third motor 20, and the first bevel gear 18 drives the second bevel gear 19 to rotate, and the second bevel gear 19 drives the de-icing wheel 6 to rotate to remove ice.

[0038] As a preferred technical solution in the present invention, the two vertical movable plates 2 are each installed with an arc heating plate 21 on one side close to each other, and the two arc heating plates 21 are installed with an arc heating belt on one side close to each other. The two arc heating plates 21 are connected to the corresponding vertical movable plates 2 via an elastic telescopic rod 22 on one side away from each other. In practice, the surface of the high-voltage line 3 can be heated by the arc heating belt, and after heating the ice that has not been cleaned up, the ice can melt and fall off faster.

[0039] As a preferred technical solution in the present invention, the elastic telescopic rod 22 includes an outer sleeve and an inner sliding rod, the outer sleeve is fixed on the arc heating plate 21, one end of the inner sliding rod is slidably connected to the outer sleeve, and the other end of the inner sliding rod is connected to a spring, and the two ends of the spring are respectively abutted against the outer sleeve and the arc heating plate 21; the vertical movable plate 2 is provided with a first through hole for facilitating one end of the inner sliding rod to pass through the vertical movable plate 2, the first through hole is provided with an annular limiting groove at one end near the outer side of the vertical movable plate 2, and a battery compartment with a built-in battery is provided at one end of the inner sliding rod for powering the arc heating belt through the battery; a sealing cover is threadedly connected at the port of the battery compartment, and the edge of the sealing cover matches and abuts against the annular limiting groove, thereby limiting the arc heating plate 21 to prevent the arc heating plate 21 from falling off. In practice, the spring is set to a compressed state, thereby allowing the arc heating belt to fit more closely to the surface of the high-voltage line 3, so that the heating effect of the arc heating belt is better.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
