Description

Technical Field

[0001] The invention belongs to the technical field of power transmission, and in particular relates to a floating line crossing support device. Background Art

[0002] In the transmission line erection project, the line often needs to cross 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 erecting a spanning frame for 110kV and above lines under power, 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 floating line crossing support device to solve the problems of poor safety and economy and long deployment 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 closing operations.

The floating unit 1 is a concave-shaped floating unit, and the floating unit 1 includes a bearing body and a guard wall, and the guard wall is arranged at both ends of the bearing body; a recessed portion is formed between the bearing body and the guard wall, and the recessed portion can support the power transmission line, and the guard wall is used to prevent the power transmission line from escaping from the recessed portion and falling under the floating unit 1. When laying the line, it is only necessary to fill the floating unit 1 of the supporting device of this embodiment with helium, and the supporting device can complete the deployment and layout, with high safety and economy, simple operation, and short deployment time.

[0041] Preferably, the control unit 3 includes a main control module 31, a connection module 32 and a wind speed sensor (not shown in the figure). The wind speed sensor is arranged on the floating unit 1. The wind speed sensor and the driving unit 2 are both connected to the main control module 31 through the connection module 32. The wind speed sensor can sense the wind direction and wind speed in the airspace where the floating unit 1 is located, and transmit them to the main control module 31 through the connection module 32.

The driver is a blade driver or a ducted fan driver. The motor is connected to the main control module 31. The drive unit 2 can make the support device of this embodiment move autonomously, so that the floating unit 1 moves to the construction airspace.

[0043] According to the provisions of the "Safety Work Regulations for Electric 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 supporting device in this embodiment are: maximum working wind speed of 13.8m / s (10m above the ground, 10min average wind speed).

[0044] The wind load calculation of the supporting device in this embodiment is based on the basic design parameters and requirements of the "Crane Design Code" (GB / T3811):

[0045] The calculation formula for wind pressure is:

[0046] P=0.5ρV S 2 ;

[0047] 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.

[0048] The calculation formula for wind load is:

[0049] P W =PA

[0050] Among them, P W is the wind load acting on the floating unit 1, in N; A is the equivalent windward area of ​​the floating unit 1 perpendicular to the wind direction, in m 2 The floating unit 1 includes a first side wall and a second side wall, wherein the first side wall is a side wall between the first driving module 21 and the second driving module 22, and the second side wall is a side wall between the second driving module 22 and the third driving module 23. 1 is the area of ​​the first side wall, A 2 is the area of ​​the second side wall.

[0051] 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°.

[0052] Case 1: The wind load is applied vertically to the first side wall, the driving unit 2 only turns on the first driving module 21 and the second driving module 22, the main control module 31 controls the driver to turn in the upwind direction, and generates power to drive the supporting device of this embodiment to move;

[0053] A=A 2 ;

[0054] F 1 =F 2 =P W / 2=PA 1 / 2;

[0055] Among them, F 1 The driving force provided by the first driving module 21, F 2 The driving force provided by the second driving module 22, the unit is N;

[0056] Case 2: The wind load is applied to the first side wall and the second side wall, the driving unit 2 only turns on the first driving module 21, the second driving module 22 and the third driving module 23, the main control module 31 controls the driver to turn in the upwind direction, and generates power to drive the supporting device of this embodiment to move;

[0057] A=A 1 Sinα+A 2 Cosα;

[0058] F 1 =F 2 =F 3 =P W / 3=P(A 1 Sinα+A 2 Cosα) / 3;

[0059] Among them, F 1 The driving force provided by the first driving module 21, F 2 The driving force provided by the second driving module 22, F 3 The driving force provided for the third driving module 23 is in N.

[0060] Preferably, if Figure 2 As shown, the supporting device of this embodiment further includes a sliding unit 4, which is arranged on the skin. The sliding unit 4 includes a plurality of rotating rods, which are rotatably connected to the retaining wall, and the rotating rods can rotate and are used to support the transmission line to prevent the transmission line from generating sliding friction with the floating unit 1, thereby protecting the transmission line and the floating unit 1 and facilitating the installation of the transmission line.

[0061] Preferably, the supporting device of this embodiment further includes a counterweight unit 5, which includes four counterweight modules, and the four counterweight modules are respectively arranged on the skins at both ends of the floating unit 1. The counterweight module includes a water tank and a water pump, and the water tanks of the four counterweight modules are interconnected through a water channel, and the water pumps of the four counterweight modules are connected to the main control module 31 through a circuit. The main control module 31 can fill water into the water tank through the water channel, and can control the water pumps of the four counterweight modules through the circuit to distribute the water in the water tanks of the four counterweight modules. By adjusting the water storage volume of the four counterweight modules, the posture of the floating unit 1 of this embodiment is adjusted and the floating posture is maintained, which is convenient for the installation of the transmission line.

[0062] According to calculations, the lift that helium can provide is: 1 cubic meter of helium can provide about 10N of lift in the atmosphere.

[0063] For a newly built 500kV line crossing a 220kV or lower operating line, the size of the floating unit 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 floating unit 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 floating unit 1 carries about 10kN and mainly plays a bearing role. In the broken 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 floating unit 1 meets the engineering requirements. If the span exceeds 300 meters, the length, width and height of the floating unit 1 can be increased to increase the volume to meet the buoyancy requirements.

[0064] Helium is expensive, so it can be recycled by the manufacturer. By collecting and releasing helium on the vehicle, the overall equipment price can be reduced; at the same time, the impact of helium on the atmospheric environment can also be reduced. Theoretically, the time for filling and recovering gas can be controlled within 2 hours.

[0066] The overall cost of the equipment is controllable and can adapt to most cross-construction environments across the country. The floating device controls the overall size and lift through modularization.

[0067] Compared with the prior art scheme of erecting a spanning frame and using the newly built iron towers and poles on both sides of the spanned line to set up crossbars for network sealing operations, it is only necessary to fill the floating unit 1 of the supporting device of this embodiment with helium, and the supporting device can complete the deployment and deployment, with high safety and economy, simple deployment operation and short deployment time; the driving unit 2 can make the supporting device of this embodiment move autonomously, so that the floating unit 1 moves to the construction airspace, and the main control module 31 can send a control signal to the driving module according to the wind direction and wind speed, and provide the floating unit 1 with a driving force in the direction of the wind by controlling the switches and speeds of the four driving modules respectively, so that the floating unit 1 remains stationary and prevents the floating unit 1 from changing its position and affecting the erection of the transmission line; the main control module 31 can fill the water tank with water through the waterway, and can control the water pumps of the four counterweight modules to distribute the water in the water tanks of the four counterweight modules, and adjust the posture of the floating unit 1 of this embodiment by adjusting the water storage capacity of the four counterweight modules, and maintain the floating posture, which is convenient for the erection of the transmission line.
