A small lever-type energy-saving ship lift and its operation method

Abstract

The invention discloses a small lever type energy-saving ship lift and an operation method thereof. The small lever type energy-saving ship lift is applicable to ship navigation of small water retaining structures. The ship lift comprises an upstream approach channel, an upper lock head, a ship chamber section, a lower lock head and a downstream approach channel which are sequentially intercommunicated with one another from upstream to downstream. The ship lift is characterized in that the ship chamber section comprises a lever, a transmission shaft and two cylindrical type ship bearing chambers, wherein the transmission shaft is of a driving braking structure, and two ends of the transmission shaft are connected to a dam body or a firm foundation rock; the transmission shaft is rigidly connected to the middle part of the lever; the two cylindrical ship bearing chambers are correspondingly connected to two ends of the lever. The ship lift is applicable to one-way navigation or two-waynavigation of a ship, so that the ship navigation efficiency is improved; moreover, the gravitational potential energy of ships at the upstream and the downstream can be converted with each other based on the lever principle, so that the transferring energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a small lever type energy-saving ship lift and its operation method. Background technique [0002] A large number of water-retaining structures such as dams have been built in the mountainous rivers of my country. In order to solve the navigation problem of ships upstream and downstream of the water-retaining structures, navigation structures (ship locks or ship lifts) need to be built. The operation of the lock consumes a lot of water, and the transportation efficiency is low. Compared with ship locks, ship lifts can adapt to higher water heads, consume less water, and have higher navigation efficiency. However, the investment is high and the technology is difficult. The traditional ship lift consumes a lot of energy for a single lift, and it is not economical for small projects with low water head. [0003] Ship lifts are mainly divided into vertical shi...
