Description

Technical Field

[0001] The present invention relates to the technical field of power grid deicing, and in particular to a power grid deicing device for electric power environmental protection and energy saving. Background Art

[0002] Icing on the power grid has a significant impact on normal power transmission. Ice covering the cables may cause them to bear greater tension. If the ice layer is too thick, the cables may sag more severely or even break, especially in areas with a large span between two poles. In this case, the structural integrity of the cables will be threatened, which may cause power outages or require emergency repairs. The ice layer may contain conductive impurities or form conductive channels after melting, resulting in reduced insulation performance, causing discharge, leakage or even short circuit. Ice coverage may cause uneven electric field distribution, local discharge (corona) accelerates insulation aging, and may break through the insulation layer in the long term, causing property damage and safety accidents. The power grid needs to be de-iced.

[0003] Traditionally, manual de-icing of power grids poses a great safety hazard in cold environments. With the development of technology, power grid de-icing devices are gradually being used for automatic de-icing. Current power grid de-icing devices usually use mechanical mechanisms that can move along the cables. As the de-icing device moves, the ice and snow on the cable surface are scraped off. This de-icing method requires the equipment to be installed on the cables, which further increases the stress on the cables and makes the cables prone to breakage. Therefore, we propose a power grid de-icing device for power environmental protection and energy saving, which can reduce the pressure of the device itself on the cables, reduce the stress on the cables, and de-ice the power grid more safely. Summary of the Invention

[0004] The present invention proposes a power grid deicing device for electric power environmental protection and energy saving, which solves the problem in the prior art that the device is installed on the cable, increasing the stress on the cable and increasing the risk of cable breakage.

DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making any creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 7As shown, this embodiment proposes a power grid de-icing device for electric power environmental protection and energy saving, including a movable seat 1, a cable 2 located inside the movable seat 1, and also including a heating component, a connecting frame, an aircraft 3 and a walking mechanism. Compared with the power grid de-icing device in the prior art, the present invention uses the aircraft 3 to enable the movable seat 1 and the heating chamber 101 to apply an upward force to the cable 2, so as to avoid the weight of the de-icing device itself increasing the risk of sagging and breaking of the cable 2. The movable seat 1 is moved along the cable 2 by rotating the roller 302 and the anti-slip pad 303, and the hot air at the heating chamber 101 is diffused by the fan blades 502 to improve the de-icing efficiency. At the same time, the reaction force of the fan blades 502 blowing air can assist the movement of the movable seat 1, and the blowing direction of the fan blades 502 is changed by rotating the conversion shaft 503 to adapt to the reciprocating movement of the movable seat 1, so as to heat and de-ice different areas of the cable 2.

[0022] The heating component is arranged on the mobile base 1 and is used to heat the power grid. The heating component includes a heating chamber 101 and a heater 102. The heating chamber 101 is fixedly connected to the mobile base 1. The heater 102 is installed inside the heating chamber 101. There are two heating chambers 101, which are fixedly connected to both ends of the mobile base 1. The heating chamber 101 is a hollow structure. The heater 102 can be an electric heating wire. The heater 102 is located inside the heating chamber 101. A battery is installed on the mobile base 1 for mobile power supply to the electric heating wire. When the heater 102 is powered on, The temperature is raised, and the heating chamber 101 is heated. The cable 2 is located inside the heating chamber 101. The heating chamber 101 can heat the ice and snow on the surface of the cable 2 to melt it, thereby realizing de-icing of the power grid. The heating chamber 101 is in a circular shape, which reduces the friction between it and the cable 2, thereby reducing the damage to the cable 2 and reducing the resistance to the movement of the mobile seat 1 and the heating chamber 101. A plurality of drainage holes are provided at the bottom of the mobile seat 1, and the melted water from the ice and snow can drip through the drainage holes, thereby preventing the melted water from accumulating inside the mobile seat 1, increasing the weight of the device and causing the mobile seat 1 to cool down.

[0023] There are multiple movable seats 1, and the connecting frame is used to connect multiple movable seats 1. The aircraft 3 is installed on the connecting frame, and the inner bottom wall of the heating chamber 101 is in contact with the cable 2. The connecting frame is a retractable structure. The connecting frame includes a fixed frame 201 and a sliding frame 202. The aircraft 3 is installed on the fixed frame 201, and the sliding frame 202 is fixedly connected to the movable seat 1. The sliding frame 202 and the fixed frame 201 are in sliding cooperation. The distance between the two movable seats 1 can be adjusted through the sliding cooperation between the fixed frame 201 and the sliding frame 202, so that the movable seat 1 can be set on the outside of the cable 2 at different distances. At the same time, the multiple movable seats 1 can be moved synchronously through the connecting frame. The aircraft 3 can use a drone to provide an upward power for the connecting frame, thereby reducing the downward pressure of the movable seat 1 and the heating chamber 101 on the cable 2, because the accumulation of ice and snow on the surface of the cable 2 has already created a pressure on the cable 2. The downward pressure causes the cable 2 to sag and bear a large tensile force. The aircraft 3 drives the heating chamber 101 to apply an upward force to the cable 2. While reducing the downward force on the cable 2, the pressure caused by ice and snow is relieved to a certain extent, and the cable 2 is lifted to a certain extent. At the same time, the heating chamber 101 heats and melts the ice and snow on the surface of the cable 2, reducing the risk of breakage of the cable 2. The diameters of the movable seat 1 and the heating chamber 101 are both larger than the diameter of the cable 2. There is a certain distance between the upper part of the movable seat 1 and the heating chamber 101 and the cable 2. Under the action of the aircraft 3, the inner bottom wall of the heating chamber 101 is in contact with the bottom end of the cable 2, further avoiding the downward force on the cable 2. The lift of the aircraft 3 is set in advance, which can counteract the dead weight of the power grid deicing device for energy saving or be slightly larger, to avoid the upward bending of the cable 2 caused by excessive lift.

[0024] The walking mechanism is arranged inside the mobile seat 1, and is used for driving the mobile seat 1 to move along the cable 2. The walking mechanism includes a walking frame 301, a roller 302 and an anti-skid pad 303. The walking frame 301 is connected to the inside of the mobile seat 1 through a compression spring 304 and a telescopic rod. The roller 302 is rotatably arranged on the walking frame 301, and the anti-skid pad 303 is fixedly sleeved on the outside of the roller 302. The anti-skid pad 303 is in contact with the cable 2. In order to realize the rotation of the roller 302, a walking drive component is also included. The walking drive component includes a motor 401, a driving gear 402, a transmission gear 403 and a driven gear 404. The motor 401 is installed on the walking frame 301, the driving gear 402 is fixedly connected to the output end of the motor 401, and the transmission gear 403 is rotatably connected to the walking frame 301. 403 is meshed with the driving gear 402, and the driven gear 404 is fixedly connected to the roller 302. The transmission gear 403 is located between the driving gear 402 and the driven gear 404. The driven gear 404 and the transmission gear 403 are meshed, and the compression spring 304 drives the walking frame 301 to press the anti-slip pad 303 against the surface of the cable 2. The anti-slip pad 303 is made of elastic material and there is a large sliding damping between the anti-slip pad 303 and the cable 2. The driving gear 402 is rotated by the motor 1 401, and the driven gear 404 and the roller 302 are rotated under the transmission action of the transmission gear 403. The roller 302 drives the anti-slip pad 303 to rotate, driving the movable seat 1 to move along the cable 2. The movable seat 1 can be moved back and forth along the cable 2 by the forward and reverse rotation of the motor 1 401, and different positions of the cable 2 are heated and de-iced.

[0025] In order to improve the heating effect of the heating component on the cable 2, a hot air diffusion component is also included. The hot air diffusion component includes a driving rod 501 and a fan blade 502. The driving rod 501 is rotatably set on the mobile seat 1. The fan blade 502 is fixedly connected to the driving rod 501. The blowing direction of the fan blade 502 is in the opposite direction of the moving direction of the mobile seat 1. There are two fan blades 502, which are fixedly connected to the two ends of the driving rod 501. A conversion shaft 503 is rotatably connected to the mobile seat 1. The driving rod 501 is rotatably connected to the conversion shaft 503. In order to realize the rotation of the fan blade 502, The hot air drive assembly includes a second motor 601, a driving gear 602 and a driven gear 603. The second motor 601 is mounted on the conversion shaft 503. The driving gear 602 is fixedly connected to the output end of the second motor 601. The driven gear 603 is fixedly sleeved on the outside of the driving rod 501. The driven gear 603 and the driving gear 602 are engaged. In order to realize the rotation of the conversion shaft 503, a rotation drive assembly is also included. The rotation drive assembly includes a driven gear ring 701 and a driving rack 702. The driven gear ring 701 is fixedly sleeved on the outside of the conversion shaft 503. The driving rack 702 is movably arranged on the mobile base 1, and an electric cylinder 703 is installed on the mobile base 1. The driving rack 702 is fixedly connected to the output end of the electric cylinder 703. The driving rack 702 is engaged with the driven gear ring 701. The motor 2 601 can drive the active gear 602 to rotate, thereby driving the passive gear 603 and the driving rod 501 to rotate. The driving rod 501 drives the fan blades 502 at both ends to rotate. The two fan blades 502 are located on both sides of the mobile base 1, and the blowing directions of the two fan blades 502 are the same. The hot air at the heating chamber 101 and the mobile base 1 can be blown by the fan blades 502. It blows to a wider range, thereby improving the de-icing effect on the cable 2. At the same time, the reaction force generated by the fan blades 502 can assist the movement of the mobile seat 1. The blowing direction is in the opposite direction of the movement of the mobile seat 1. Therefore, the direction of the reaction force generated by the fan blades 502 is the same as the moving direction of the mobile seat 1, thereby assisting the movement of the mobile seat 1. The electric cylinder 703 can drive the driving rack 702 to move, thereby driving the driven gear ring 701 and the conversion shaft 503 to rotate, and adjusting the blowing direction of the fan blades 502 to make it opposite to the moving direction of the mobile seat 1, so as to adapt to the reciprocating movement of the mobile seat 1 on the cable 2.

[0026] It should be noted that the battery on the mobile base 1 can power electrical components such as motor 1 401, motor 2 601, aircraft 3, heating wire and electric cylinder 703, so that the power grid de-icing device for power environmental protection and energy saving can generate heat during movement to de-ice the cable 2. A distance sensor can be installed on the mobile base 1 to sense the proximity to the utility pole, and can control the motor 1 401 to reverse and control the electric cylinder 703 to drive the conversion shaft 503 to rotate 180 degrees.

[0027] The working principle or use process of the power grid deicing device for power environmental protection and energy saving is as follows: The movable base 1 is mounted on the outside of the cable 2 and connected to the movable base 1 through the connecting frame. When de-icing is required, the aircraft 3 is turned on. The aircraft 3 provides a lifting force to the connecting frame and the movable base 1, so that the inner bottom wall of the heating chamber 101 contacts the cable 2. The motor 401 drives the roller 302 and the anti-slip pad 303 to rotate, so that the movable base 1 moves along the cable 2. The heater 102 is powered on to generate heat, causing the heating chamber 101 to heat the ice and snow on the surface of the cable 2 to melt it. At the same time, the second motor 601 drives the driving rod 501 and the fan blade 502 to rotate, providing a force to assist the moving base 1 in moving forward, while blowing the hot air generated by the heating chamber 101 to other locations, thereby improving the de-icing effect on the cable 2. After moving to one side of the cable 2, the motor 401 reverses, and the electric cylinder 703 drives the conversion shaft 503 to rotate 180 degrees, so that the fan blades 502 blow air in the opposite direction, and the roller 302 rotates in the opposite direction, so that the movable base 1 moves in the opposite direction to perform reciprocating deicing on the cable 2.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
