Arresting device and method for laying stress along slope surface

Abstract

The invention provides an arresting device and method for laying stress along a slope surface. The arresting device comprises a main cable, auxiliary cables, branch cables, buoys, anchoring parts, a cable guide mechanism and an anti-blocking and resistance-reducing wheel; the auxiliary cables and the branch cables are connected to the two ends of the main cable correspondingly, the auxiliary cable and the branch cable at one end of the main cable are connected with one side of the vertical slope surface of a channel, and the auxiliary cable and the branch cable at the other end of the main cable are connected with one side of the slope surface of the channel; the buoys and the anti-blocking and resistance-reducing wheel are connected to the auxiliary cables and the branch cables, the buoys are connected to the main cable in series, and the branch cable on one side of the vertical slope surface is further connected with the cable guide mechanism; a cable force detecting device is further arranged on the auxiliary cable on one side of the slope surface, when the main cable floats up and down to drive the auxiliary cables and the branch cables to swing, the buoys and the anti-blocking and resistance-reducing wheel located on the auxiliary cables and the branch cables do not make contact with a basic surface; and when floating and accident ships are arrested, the cable force detecting device feeds back signals to conduct accurate identification, the situation that a steel wire cable is abraded and consequently is broken and loses efficacy is avoided, intercepted objects are identified and accurately judged, timely response is achieved, safety and reliability are achieved, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of dam navigation, and relates to a force-bearing arresting device and method for laying along a slope. Background technique [0002] Steel wire ropes are widely used in various engineering construction and traffic operations, especially in the construction and operation of hydropower projects. As an important force-transmitting and force-bearing structure, steel wire ropes are widely used. The construction and operation of hydropower stations are mostly located on the river channel. Many of the river channel slopes and the construction surfaces of buildings are not vertical structures, so the steel wire ropes are often in contact with the structural surfaces. Many factors are affected in the force process. As the water level fluctuates up and down, the force is uneven, and the steel wire rope swings back and forth frequently rubs against the vertical slope or slope surface or structural surface, causing th...

AI Technical Summary

Problems solved by technology

As the water level fluctuates up and down, the force is uneven, and the steel wire rope swings back and forth frequently rubs against the vertical slope or slope surface or structural surface, causing the wire rope to wear out, reducing the service life and increasing the operation and maintenance cost. The bearing capacity is reduced, and even lead to fracture failure; the channel is relatively far away from the hollow chamber, and when it is affected by rain and fog, it cannot be seen visually, resulting in the inability to accurately identify and judge intercepted objects, and cannot respond in time, posing safety hazards
