Description

[0002] The hydrological cableway is used to obtain hydrological data more accurately. Tower structures are arranged on both banks of a river, high-strength steel wires are arranged between the tower structures as bearing cables, the bearing cables bear the weight of lead fish (a weight used to carry measuring instruments), trolleys (devices that can move along the bearing cables and are connected to other components) and auxiliary measuring equipment, and ensure that they can be safely and stably suspended above the river to perform flow measurement operations.

[0003] In the prior art, the height of the tower structure is fixed, and the position of the bearing cable is also fixed. Correspondingly, the trolley moves back and forth in the same plane to drive the lead fish to measure hydrological data in the water flow.

In addition, the water depth of the river is constantly changing, so the length of the steel wire connected between the lead fish and the trolley also needs to be adjusted according to the water conditions. This not only affects the work efficiency, but also increases the measurement data deviation with the change in the length of the steel wire. SUMMARY
