Description

Technical Field

[0001] The invention relates to the technical field of cable deicing, and in particular to a cable ice removal device. Background Art

[0002] In winter, low temperature, rain and snow pose a severe challenge to the stable operation of power lines. Although power lines are designed to have a certain degree of "anti-freeze" ability, they are still prone to icing when exposed to low temperature for a long time. Icing not only causes the weight of transmission lines to increase significantly and cause them to bend and sag, but in severe cases it can also exceed the critical value that the wires can withstand, leading to serious accidents such as line breakage and power outages. In addition, cable icing may also cause problems such as overload, uneven icing, insulator flashover or line dancing, posing a huge threat to the safety and stability of the power system.

[0003] Currently, the methods for removing ice from cables mainly include natural deicing, mechanical deicing and thermal deicing, but each method has significant limitations and shortcomings.

[0004] Natural de-icing methods rely on natural conditions and are only suitable for sporadic rain and snow weather. They have limited effects and can only be used as an auxiliary means and cannot cope with large-scale or continuous icing problems.

[0005] Although mechanical deicing technology has improved deicing efficiency to a certain extent, there are many challenges. Although the deicing method of human traction equipment is simple to implement and low-cost, it has high safety risks, low efficiency, and is easy to damage wires and insulators. Although autonomous walking deicing robots have made improvements in reducing work intensity and improving safety, when the mechanical device is in direct contact with the cable, a large force is required to remove the ice, which can easily lead to risks such as damage, pits, and cracks on the cable surface. In addition, mechanical deicing is not effective for thin ice layers after removal and cannot achieve complete deicing.

[0006] Thermal deicing methods, including AC thermal deicing and DC thermal deicing, are fast and effective, but they require power outages of power lines, consume a lot of energy, require many external devices, and have high requirements on equipment performance. This method not only affects the continuity and stability of power supply, but also increases operating costs and maintenance difficulties.

[0007] In summary, the existing cable ice removal methods have limitations and deficiencies to varying degrees, and it is difficult to meet the power system's demand for efficient, safe, and reliable deicing. Therefore, developing an efficient, safe, and reliable cable ice removal technology has become a technical problem that needs to be solved urgently in the current power industry.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a cable ice removal device to solve the problems existing in the prior art. During the deicing process, a mechanical deicing mechanism is first used for mechanical deicing, and then a thermal deicing mechanism is used for heating deicing. While heating deicing, a blowing device is used for air drying. By combining mechanical, thermal, blowing and other technical means, the ice can be removed quickly, safely and completely, ensuring the stable operation of power lines under extreme weather conditions.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 to Figure 8 As shown, the present invention provides a cable ice removal device, including a walking mechanism 1, the walking mechanism 1 can adopt a rolling or sliding contact cable, and the power mode can adopt a direct drive walking wheel 12, or adopt a jet or blowing mode. The cable refers to a power supply cable erected at high altitude, mainly located in mountainous areas or open areas, where the population is relatively sparse, and there will be no personnel or buildings under the cable during the deicing process; it can also be a low-altitude cable, or other non-powered cables with deicing requirements. For the latter case, during deicing, a safe area can be set to prevent people from entering. In addition, since it is a low-altitude cable, it has little impact on the building and no measures need to be taken. The walking mechanism 1 is used to walk along the length direction of the cable to drive the entire cable ice removal device to move on the cable to achieve gradual deicing. The walking speed can also be controlled by a control device, that is, the walking speed can be changed according to the ice covering and deicing conditions. For example, the speed can be slowed down when the deicing effect is poor, and the speed can be increased when the deicing effect is good. It also includes a thermal deicing mechanism 2, which includes a heating device and a blowing device. The heating device has a heating channel for the cable to pass through. The heating device is used to heat the heating channel, thereby melting the ice on the surface of the cable in the heating channel. The heating device can use known microwave heating, electromagnetic heating, resistance heating and other methods. The blowing device is used to blow air into the heating channel to dry the melted water layer or water vapor to avoid re-freezing. It also includes a mechanical deicing mechanism 3, which removes the ice by beating, cutting, vibration and other methods. In the walking direction of the walking mechanism 1, the mechanical deicing mechanism 3 is located in front of the thermal deicing mechanism 2, that is, in the deicing process, mechanical deicing is performed first, and then thermal deicing and air drying are performed.

[0036] In summary, the present invention includes a mechanical deicing mechanism 3, a thermal deicing mechanism 2 and a blowing device. The mechanical deicing mechanism 3 is located in front of the thermal deicing mechanism 2. During the deicing process, the mechanical deicing mechanism 3 can be used for mechanical deicing first, and then the thermal deicing mechanism 2 can be used for heating deicing. In addition, the blowing device can be used for air drying while heating deicing. By combining mechanical, thermal, blowing and other technical means, the ice can be removed quickly, safely and completely, ensuring the stable operation of power lines and other cables under extreme weather conditions.

[0037] In one embodiment, the heating device includes a top plate 21 and a cover plate 22 rotatably connected to both sides of the top plate 21. It should be noted that: Figure 6The specific structure of the rotational connection between the cover plate 22 and the top plate 21 is not shown, which can be realized by a pin shaft or a hinge structure. The cover plate 22 is connected with an opening and closing structure, and the opening and closing of the cover plate 22 can be controlled by the opening and closing structure. After the cover plate 22 is opened, a path for the cable to enter and exit radially can be formed. After the cover plate 22 is closed, a heating channel for the cable to pass axially and heat the cable can be formed between the cover plates 22. In addition, since the cable is not a completely straight line, but has a certain curvature, for this reason, the cover plate 22 can be set to a concave curve, which can be a semicircle, an ellipse or other forms.

[0038] In one embodiment, the opening and closing structure may include a first telescopic mechanism 23, the movable end of the first telescopic mechanism 23 is connected to the cover plate 22 through a connecting rod mechanism 24, and the fixed end of the first telescopic mechanism 23 is connected to the top plate 21. When the first telescopic mechanism 23 is extended, the cover plate 22 falls and is buckled. When the first telescopic mechanism 23 is shortened, the cover plate 22 is pulled open to achieve the opening of the cover plate 22. The first telescopic mechanism 23 can adopt an electric telescopic rod, a screw nut structure or an electromagnetic structure. When the electromagnetic structure is adopted, the following control method can be adopted: when the electromagnetic structure is not powered on, it is in an extended state, that is, the cover 22 remains buckled; when the electromagnetic structure is powered on, it is in a shortened state, that is, the cover 22 is pulled open. Under this control method, when the cable ice removal device is performing de-icing work on the cable, the electromagnetic structure does not consume electricity, and only consumes electricity when placing and retrieving the cable ice removal device, thereby reducing energy loss; of course, the opposite control method can also be adopted, that is, when the electromagnetic structure is not powered on, the cover 22 is open, and when the electromagnetic structure is powered on, the cover 22 is buckled.

[0039] In one embodiment, the cover plate 22 includes an inner wall surface and an outer wall surface, and there is a sandwich between the inner wall surface and the outer wall surface, and an electromagnetic heater 26 is arranged in the sandwich. The electromagnetic heater 26 generates heat after being energized. Since the electromagnetic heater 26 is located inside the sandwich of the cover plate 22, the electromagnetic heater 26 does not directly contact the ice. Therefore, on the one hand, the cover plate 22 can be used to contact the ice to achieve ice melting, and on the other hand, the heat for melting the ice can be accumulated in the heating channel to achieve ice melting. Regarding the selection of the electromagnetic heater 26, considering that the surface of the overhead cable is an aluminum cable, if microwave heating is used for deicing, it is easy to generate an arc to break down the equipment or other safety accidents, and electromagnetic heating does not have this risk. In addition, if laser heating is used for deicing, considering that the surface of the ice layer is close to a smooth mirror, the efficiency of laser heating for deicing is greatly reduced. Therefore, the use of the electromagnetic heater 26 can eliminate the above risks and achieve a higher ice melting efficiency. When the electromagnetic heater 26 is set, the heating coil can be spirally wound on the iron core, and a threaded hole is set at the end of the iron core, and the iron core is fixed on the cover plate 22.

[0040] In one embodiment, the blowing device includes a blower 25 disposed on the top plate 21, and the top plate 21 is provided with a blowing port 211. The air outlet of the blower 25 blows air into the heating channel through the blowing port 211, and the water vapor in the heating channel and on the cable surface is accelerated by blowing. The blower 25 can be a warm air blower or a cold air blower. The warm air blower can further increase the supply of warm air, so as to better remove the water vapor. Even if a cold air blower is used, the cold air blown by the cold air blower can be heated by the existing electromagnetic heater 26, and the cold air is heated into hot air, thereby achieving efficient removal of water vapor.

[0041] In one embodiment, the mechanical deicing mechanism 3 includes a cantilever bracket 31 and a slicing motor 321 connected to the free end of the cantilever bracket 31, and the slicing motor 321 is connected to a rotating slicer 32, and the slicing motor 321 drives the rotating slicer 32 to rotate to achieve the removal of the hanging large ice cone, thereby clearing obstacles for the normal operation of the subsequent thermal deicing mechanism 2. The fixed end of the cantilever bracket 31 is connected to the walking mechanism 1, for example, connected to the walking bracket 11 of the walking mechanism 1, and the walking mechanism 1 drives the cantilever bracket 31 and then drives the rotating slicer 32 to move, thereby achieving the gradual advancement of mechanical deicing.

[0042] In one embodiment, the mechanical deicing mechanism 3 further includes a second telescopic mechanism 33, the movable end of the second telescopic mechanism 33 is connected to the fixed end of the cantilever bracket 31, and the fixed end of the second telescopic mechanism 33 is connected to the walking mechanism 1. The second telescopic mechanism 33 can drive the cantilever bracket 31 to move, thereby driving the rotating slice 32 to move closer to or away from the cable, thereby achieving effective removal of ice of different sizes. In addition, the mechanical deicing mechanism 3 can be arranged in a central symmetrical manner, which can not only achieve the center of gravity balance of the cable ice removal device, but also can work together up and down to achieve the removal of ice from different parts of the cable.

[0043] In one embodiment, the traveling mechanism 1 includes a traveling support 11, a traveling wheel 12 and a clamping wheel 13. The traveling support 11 may be U-shaped so as to have a space for accommodating cables, and the cables can enter and exit through the U-shaped opening. The traveling wheel 12 is rotatably connected to the traveling support 11 and driven to rotate by the traveling motor 121. The clamping wheel 13 is connected to the third telescopic mechanism 131, the movable end of the third telescopic mechanism 131 is connected to the clamping wheel 13, and the fixed end of the third telescopic mechanism 131 is connected to the traveling support 11. Through the extension and contraction of the third telescopic mechanism 131, the clamping wheel 13 can be controlled to move closer to or away from the traveling wheel 12. A traveling channel through which the cable passes is formed between the traveling wheel 12 and the clamping wheel 13. Before the cable enters the traveling channel, the distance between the traveling wheel 12 and the clamping wheel 13 can be expanded by the third telescopic mechanism 131, and after the cable enters the traveling channel, the distance between the traveling wheel 12 and the clamping wheel 13 can be reduced by the third telescopic mechanism 131. When crossing obstacles, the clamping wheel 13 can be lowered to enhance the obstacle crossing capability of the cable ice removal device. Through the action of the clamping wheel 13, on the one hand, it can cooperate with the travel wheel 12 to increase the friction of walking after lightly compressing the cable, which is conducive to walking; on the other hand, it can cooperate with the travel wheel 12 to significantly increase the friction after heavily compressing the cable, thereby restricting walking. The third telescopic mechanism 131 can adopt a structure in the form of an electric push rod, a lead screw nut, etc. In addition, if Figure 5 As shown, the travel wheels 12 and the pressure wheels 13 may be arranged in an interval arrangement, that is, the pressure wheels 13 correspond to the spaces between adjacent travel wheels 12, so as to achieve a better compression state for the cables and avoid slipping when the travel mechanism 1 is traveling.

[0044] In one embodiment, the front and rear sides of the thermal deicing mechanism 2 are respectively connected to a front traveling mechanism and a rear traveling mechanism, and both the front traveling mechanism and the rear traveling mechanism adopt the traveling mechanism 1 described above. The arrangement of the traveling mechanism 1 at both the front and rear sides can make the cable ice removal device more stably clamped on the cable, and the wheel system composed of the traveling wheel 12 and the clamping wheel 13 can be used to limit and correct the cable passing through the thermal deicing mechanism 2, so as to ensure that the cable passes through the heating channel smoothly and avoids ice obstruction. In addition, the front traveling mechanism and the rear traveling mechanism can be arranged axially symmetrically or centrally symmetrically. When the centrally symmetrical arrangement is adopted, the wheel system composed of the traveling wheel 12 and the clamping wheel 13 will be distributed on both sides of the cable. In this way, the center of gravity distribution of the cable ice removal device can be balanced, and the running stability of the entire device can be maintained.

[0045] In one embodiment, a battery 4 for supplying electric energy is arranged on the top of the cable ice removal device, the battery 4 spans the thermal deicing mechanism 2, and both ends of the battery 4 are respectively connected to the traveling bracket 11 of the front traveling mechanism and the traveling bracket 11 of the rear traveling mechanism. The entire cable ice removal device is adjusted and arranged with the center of gravity to ensure that the center of gravity is located in the lower middle part to ensure stable operation on the cable.

[0046] In one embodiment, the first camera 6, the second camera 7 and the speed sensor 5 are included. The first camera 6 can be installed on the front walking mechanism to monitor the deicing of the mechanical deicing mechanism 3. By monitoring the specifications of the front ice cone, the lifting and lowering of the rotating slice 32 can be remotely controlled to ensure the efficiency of ice cone removal and avoid jamming during the walking of the cable ice removal device. In addition, the first camera 6 can also be used to observe the front working conditions. During the downward process, the walking motor 121 stops supplying power to reduce power loss and increase the robot's endurance; during the climbing process, the walking motor 121 is restarted to provide power for the walking of the cable ice removal device. The second camera 7 can be set at the bottom of the top plate 21, that is, located inside the heating channel, to monitor the deicing of the thermal deicing mechanism 2. By monitoring the melting of thin ice on the cable, the power of the walking mechanism 1 is reduced for the position where the ice is not fully melted. The braking can be achieved by increasing the pressing force of the upward pressing wheel 13, extending the thermal ice melting time, and thus ensuring that there is no thin ice residue. The speed sensor 5 can be set on the front traveling mechanism or the rear traveling mechanism to monitor the traveling speed of the traveling mechanism 1. When the speed is too fast, the ice melting efficiency will be reduced. At this time, the third telescopic mechanism 131 is controlled in linkage to lift the clamping wheel 13 upward to increase the friction between the traveling mechanism 1 and the cable and reduce the running speed to ensure the ice melting efficiency.

[0047] In one embodiment, a cable ice removal device is hoisted by a drone, so that the cable is placed between the walking wheel 12 and the clamping wheel 13, the first telescopic mechanism 23 is actuated, the cover plate 22 of the thermal deicing mechanism 2 buckles the cable in the heating channel, the mechanical deicing mechanism 3 is started, so that the rotating slice 32 starts to remove the larger ice cone, and then the walking mechanism 1 is started to drive the cable ice removal device to start walking. At the same time, the heating device and the blowing device in the thermal deicing mechanism 2 are started to heat the heating channel, and the blowing device is used to air dry the water vapor on the cable surface and in the heating channel. Through intelligent devices such as the speed sensor 5, the first camera 6, and the second camera 7, the walking mechanism 1 and the heating power, heating time, heating power, and other technical parameters that affect power consumption and deicing efficiency of the thermal deicing mechanism 2 are linked to control the walking of the walking mechanism 1, and the heating power, heating time, and heating power of the thermal deicing mechanism 2, so as to better achieve the integration of efficient deicing and intelligent control, energy saving and emission reduction.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
