Self-adjusting water intake device

Abstract

The invention relates to the field of ecological water intake engineering and discloses a water intake device, which comprises a main gate, big wells, small wells, big water tanks, small water tanks, small gates and a low weir. The device is characterized in that the main gate is connected with big water tanks by a wire rope through fixed pulleys on a cross beam, the big water tanks are arranged in the big wells, the low weir is arranged under the main gate, each of the big wells and each of the small wells are arranged on each side of the main gate, the small gates in the big wells are connected with the small water tanks in the small wells through a wire rope and fixed pulleys on adjoining walls of the small wells, a high hole and a low hole are arranged on adjoining walls of the small wells and the big wells and the small wells are connected with water body through a catchment channel. Based on buoyancy and lever principles, by using the water tanks which rise and sink freely with water to control switches of the gates through the fixed pulleys and coordinating with the low weir, the device can meet the requirement of ecological water use of landscapes. Moreover, the device has the advantages of no energy consumption, full automation, few investment, simple structure, low operation cost and high safe performance. Simultaneously, the device is capable of integrating with the surroundings so as to embody a low-carbon ecological concept.

Description

technical field [0001] The invention relates to a self-regulating water intake device. The device of the invention is applicable to the field of ecological water intake engineering. Background technique: [0002] "Hydrophilicity" is one of the mainstream elements of modern urban construction in my country. In the process of urban landscape construction, the construction of landscape water bodies is often an indispensable part. Due to the growth needs of landscape plants and the display of comprehensive landscape effects, the water level of landscape water needs to be kept within a reasonable range all year round. Therefore, certain control measures need to be taken at the water intake. At present, multi-purpose gates are used for control. When the landscape water level is lower than the minimum water level, the gates will be opened to release water. When the water level reaches the normal water storage level, the gates will be closed. The opening and closing of the gate ...

AI Technical Summary

Problems solved by technology

The opening and closing of the gate is generally opened and closed by electric or flashlight dual-purpose hoist, and the intelligent opening and closing of the gate also adopts the remote control method. This control method not only requires manpower or electric operation, but also sometimes requires special instruments and special Management, there are disadvantages such as troublesome operation, large investment, high operating cost, and certain hidden safety hazards in manual operation

In order to solve the above shortcomings, Chinese patents "200920115264.6" and "CN200910097011.5" respectively announced a jacking-type hydraulic self-control gate and a louver-type hydraulic self-control gate, which can realize the comprehensive utilization of tidal hydropower resources in coastal areas along the river. China Patent "200810025345.9" discloses a hydraulic self-control gate, which can realize the function of venting excess flood in reservoirs and rivers; however, none of the above patents can meet the requirement of always controlling the water level within a certain range under the condition that the water level of the outer channel is constantly changing
