Description

Technical Field

[0001] The invention belongs to the technical field of power transmission, and in particular relates to a high-altitude protective device for erecting high-voltage lines. Background Art

[0002] In the high-voltage transmission line erection project, the line often needs to cross over existing high-voltage power lines, high-speed railways, highways, etc., and it is necessary to carry out the construction of the spanning line. The spanning line construction technology can be divided into conventional steel pipe or bamboo spanning frames, suspension spanning, and mechanical spanning frames. The spanning frame is built to provide support for the insulation net to ensure that a safe distance is maintained between the erected line and the object being crossed; the suspension spanning hangs the protective insulation net on the cross arm or false cross arm of the iron tower, and uses the iron tower support to complete the sealing of the object being crossed. There is a great safety risk in the live spanning frame for the 110kV and above lines being crossed, especially when the height of the line being crossed exceeds 30 meters, the difficulty of using the ground support to build the spanning frame will increase significantly, and the safety risk level will also increase. When adopting the bamboo spanning frame erection scheme, a large amount of materials (bamboo, wire, drill pile, insulation rope, safety net, wire, etc.) and manpower are required, the cost is high, and the erection time is long. For the spanning frame with a height of about 30 meters, the erection time is about one week. Therefore, the plan of erecting a crossing frame performed poorly in terms of safety, economy and progress.

[0003] In addition, the newly built iron towers and poles on both sides of the crossed lines can be used to set up crossbars for network sealing operations. However, before closing the network, the power lines must be shut down, the guide ropes must be deployed, and the load-bearing ropes must be pulled. When using poles to set up crossbars to seal the network, although the cost and construction period are reduced compared to setting up a spanning frame, the poles are relatively heavy and difficult to transport, set up, and adjust. At the same time, the required materials (poles, wire ropes), machinery (motorized winches), and manpower are still relatively large.

[0004] Whether it is a spanning frame or a suspended cable spanning closure, power outage or suspension is required to cooperate with the closure, and power outage is also required during the deployment of the conductor to reduce safety risks. This is because during the deployment of the conductor, if the traction rope breaks or other unexpected situations occur, the conductor will fall and impact the closure frame, which may damage the closure and cause an accident. The main reason is that the vertical distance between the closure and the conductor is large, and it is a soft cable. The impact force generated after the conductor breaks is very large, which can easily cause the closure to fail.

[0005] Therefore, there is an urgent need for a high-altitude protective device for the installation of high-voltage lines to solve the problems of poor safety and economy and long installation time in the existing technology of erecting a crossing frame and using newly built iron towers and poles on both sides of the crossed line to set up cross bars for network sealing operations.

[0040] Embodiment 1: A specific embodiment of the present invention, as Figure 1 and Figure 2As shown, a high-altitude protective device for high-voltage line erection (hereinafter referred to as the protective device) is disclosed, including a suspension mechanism 1, a power mechanism 2 and a control mechanism 3. The power mechanism 2 is arranged on the suspension mechanism 1, and the control mechanism 3 is connected to the power mechanism 2. The suspension mechanism 1 can float in the air to isolate the newly erected transmission line from the existing transmission line or surface facilities to perform crossing construction. The control mechanism 3 is used to control the power mechanism 2, and the power mechanism 2 is used to drive the suspension mechanism 1 to make the suspension mechanism 1 move and remain in the construction airspace.

[0041] Preferably, the suspension mechanism 1 includes a skin and helium, and the skin can be filled with helium, so that the suspension mechanism 1 can be suspended in the air. When laying the line, it is only necessary to fill the suspension mechanism 1 of the protective device of this embodiment with helium, and the protective device can be deployed and laid, with high safety and economy, simple operation, and short deployment time.

[0042] Preferably, the control mechanism 3 includes a controller 31, a pipeline 32 and a wind speed sensor (not shown in the figure). The wind speed sensor is arranged on the suspension mechanism 1. The wind speed sensor and the power mechanism 2 are both connected to the controller 31 through the pipeline 32. The wind speed sensor can sense the wind direction and wind speed in the airspace where the suspension mechanism 1 is located, and transmit them to the controller 31 through the pipeline 32. The pipeline 32 includes an air pipe and an electric wire.

[0043] Preferably, if Figure 3 As shown, the power mechanism 2 includes a first power module 21, a second power module 22, a third power module 23 and a fourth power module 24, which are respectively arranged on the skins at both ends of the suspension mechanism 1, and the structures of the first power module 21, the second power module 22, the third power module 23 and the fourth power module 24 are the same. The first power module 21 includes a motor and a driver, the motor is used to drive the driver to rotate and generate power to drive the movement of the protective device of this embodiment, and the driver is a blade driver or a ducted fan driver. The motor is connected to the controller 31. The power mechanism 2 can make the protective device of this embodiment move autonomously, so that the suspension mechanism 1 moves to the construction airspace.

[0044] According to the provisions of the "Safety Work Regulations for Power Construction", high-altitude operations are not allowed in winds of level 6 or above. Therefore, the permissible meteorological conditions for the design of the protective device in this embodiment are: maximum working wind speed of 13.8m / s (10m above the ground, 10min average wind speed).

[0045] The wind load calculation of the protective device in this embodiment is based on the basic design parameters and requirements of the "Crane Design Code" (GB / T3811):

[0046] The calculation formula for wind pressure is:

[0047] P=0.5ρV S 2 ;

[0048] Where P is wind pressure, unit is N / m 2 ; V S is the wind speed, in m / s; ρ is the air density, in kg / m³.

[0049] The calculation formula for wind load is:

[0050] P W =PA

[0051] Among them, P W is the wind load acting on the suspension mechanism 1, in N; A is the equivalent windward area of ​​the suspension mechanism 1 perpendicular to the wind direction, in m 2 The suspension mechanism 1 includes a first side wall and a second side wall, wherein the first side wall is a side wall between the first power module 21 and the second power module 22, and the second side wall is a side wall between the second power module 22 and the third power module 23. A1 is the area of ​​the first side wall, and A2 is the area of ​​the second side wall.

[0052] The angle between the wind direction and the first side wall is α; there are two cases of α, namely, α= 90° and α< 90°.

[0053] Case 1: The wind load is applied vertically to the first side wall, the power mechanism 2 only turns on the first power module 21 and the second power module 22, the controller 31 controls the driver to turn in the upwind direction, and generates power to drive the protective device of this embodiment to move;

[0054] A=A2;

[0055] F1=F2=P W / 2=PA1 / 2;

[0056] Wherein, F1 is the driving force provided by the first power module 21, and F2 is the driving force provided by the second power module 22, both in N.

[0057] Case 2: The wind load is applied to the first side wall and the second side wall, the power mechanism 2 only turns on the first power module 21, the second power module 22 and the third power module 23, the controller 31 controls the driver to turn in the upwind direction, and generates power to drive the protective device of this embodiment to move;

[0058] A = A1Sinα + A2Cosα;

[0059] F1=F2=F3=P W / 3=P(A1Sinα+A2Cosα) / 3;

[0060] Among them, F1 is the driving force provided by the first power module 21, F2 is the driving force provided by the second power module 22, and F3 is the driving force provided by the third power module 23, and the unit is N.

[0061] Preferably, if Figure 2 As shown, the protective device of this embodiment further includes a sliding mechanism 4, which is arranged on the skin. The sliding mechanism 4 includes a plurality of rotating rods, which can rotate and are used to support the transmission line to prevent the transmission line from generating sliding friction with the suspension mechanism 1, thereby protecting the transmission line and the suspension mechanism 1 and facilitating the installation of the transmission line.

[0062] Preferably, the protective device of this embodiment further includes a pulling mechanism 5, which includes four pulling modules, and the four pulling modules are respectively arranged on the skins at both ends of the suspension mechanism 1. The pulling mechanism 5 is used to connect the suspension mechanism 1 to the ground, so that the suspension mechanism 1 maintains a suspended posture, which facilitates the construction of the transmission line.

[0063] According to calculations, the lift that helium can provide is: 1 cubic meter of helium can provide about 10N of lift in the atmosphere.

[0064] For a newly built 500kV line crossing a 220kV or lower operating line, the size of the suspension mechanism 1 can be designed to be 35×6×6 meters, a total of 1260 cubic meters. For a line crossing 220kV or higher, the size of the suspension mechanism 1 can be designed to be about 55×5×5 meters, a total of 1375 cubic meters. The specific size can be adjusted according to needs. The suspension mechanism 1 carries about 10kN and mainly plays a bearing role. In the disconnected state, the deadweight of the conductor is not entirely borne by the floating device, and the specific calculation is based on the actual working conditions. If the conductor load is large, it can be deployed in batches; 630 conductors are deployed across a span of 300 meters, two conductors are pulled at a time, and the full load after the line is dropped is 1.26 tons; 1250 conductors are deployed across a span of 300 meters, one conductor is pulled at a time, and the full load after the line is dropped is 1.26 tons. The buoyancy of the suspension mechanism 1 meets the engineering requirements. If the span exceeds 300 meters, the length, width and height of the suspension mechanism 1 can be increased to increase the volume to meet the buoyancy requirements.

[0065] Compared with the prior art scheme of erecting a crossing frame and using newly built iron towers and poles on both sides of the crossed line to set up cross bars for network sealing operations, it is only necessary to fill the suspension mechanism 1 of the protective device of this embodiment with helium, and the protective device can be deployed and laid out with high safety and economy, simple deployment operation and short deployment time; the power mechanism 2 can enable the protective device of this embodiment to move autonomously, so that the suspension mechanism 1 moves to the construction airspace, and the controller 31 can send a control signal to the power module according to the wind direction and wind speed, and provide the suspension mechanism 1 with a driving force in the direction of the wind by controlling the switches and speeds of the four power modules respectively, so as to keep the suspension mechanism 1 stationary and prevent the suspension mechanism 1 from changing its position and affecting the construction of the transmission line.

[0066] Embodiment 2: After the helium is exhausted, the volume and weight of the suspension mechanism 1 are still large, which is not conducive to transportation. Therefore, the embodiment 2 provided by the present invention, such as Figure 1 As shown, the suspension mechanism 1 of embodiment 1 is improved so that the suspension mechanism 1 becomes a modular suspension mechanism.

[0067] Preferably, the suspension mechanism 1 includes a buoyancy component 11 and a connecting plate 12, and the connecting plate 12 is used to connect two buoyancy components 11.

A plurality of inflated first airbags 111 provide rigid support for the suspension module to prevent the suspension mechanism 1 from deforming in a direction perpendicular to the connecting plate 12. The suspension mechanism 1 can provide hard support for the transmission line, facilitating the line stringing operation.

[0069] When assembling the suspension mechanism 1, the user inflates it twice. The first inflation fills all the first airbags 111 with helium, so that the suspension mechanism 1 can float in the air and complete the operation of crossing the existing high-voltage power lines, high-speed railways, and highways. After that, the suspension mechanism 1 is anchored by the pulling mechanism 5, and then the second inflation is performed to fill the second airbags 112 with helium. The buoyancy provided by the second airbags 112 enables the suspension mechanism 1 to lift the transmission line and complete the transmission line hypothetical work.
