Two-way inclined ship lift

Abstract

A two-way inclined ship lift comprises a retaining dam and track sections having certain gradients relative to upstream and downstream water levels of the retaining dam, wherein the track sections and a dam body are connected through a connecting section adopting a reinforced concrete structure, ship chambers are arranged at the track sections, positioning holes are formed in the ship chambers, ships can be connected with chamber bodies through ropes, an upstream side chamber door and a downstream side chamber door which can be opened outwards are arranged at upstream and downstream ends of each ship chamber respectively, limiting pulleys are mounted at bottoms of the ship chambers, limiting pull rings are arranged on upstream sides of the ship chambers, the ship chambers can be connected with the dam body through safety ropes, a cavity is formed in the connecting section, a guide pulley block is mounted in the cavity and matched with the ship chambers through a wire rope penetrating through a reserved hole of the connecting section, and ascending and descending of the ship chambers are realized. The two-way inclined ship lift has the effects that the inclined ship lift is based on a small low-flow river channel, the dam passing requirement of small ships such as small boats, bamboo rafts, drift ships and the like can be met, the project investment is effectively reduced, manpower and electric power are saved, and the dam passing efficiency of the ships is improved.

Description

technical field [0001] The invention relates to a new type of two-way slope ship lift in the field of water conservancy engineering, which can make small boats and rafts pass through river dams simply and safely. Background technique [0002] my country has superior natural conditions for the development of shipping, with a coastline of more than 18,000 kilometers and numerous rivers and lakes. Many rivers have plenty of water and are not frozen all year round, so they can be navigated in all seasons. Water transport has the advantages of less investment in construction, quick results, and large transport volume. Therefore, the development of inland waterway shipping is of great significance to serving industrial and agricultural production, facilitating material exchange and improving people's lives. After decades of construction and development, water conservancy dams have been established on many navigable rivers. In order to ensure the smooth navigation of water trans...

AI Technical Summary

Problems solved by technology

However, for small rivers with a flow rate of less than ten cubic meters per second, the ships crossing the dam are usually small boats, bamboo rafts, drifting boats, etc., and the tonnage is very small. Investment has increased substantially, and resources have not been fully utilized

At the same time, traditional ship locks or ship lifts occupy a large area and have certain requirements for topographic and geological conditions. These limiting factors make some small rivers unsuitable for the establishment of traditional navigation facilities
