Automatic telescopic water control spur dike

Abstract

The invention discloses an automatic telescopic water control spur dike. The automatic telescopic water control spur dike comprises a dike body, wherein the overall dike body is vertically arranged. The automatic telescopic water control spur dike is characterized in that an outer end section of the dike body extends out of a river way; an inner end section of the dike body is concavely arranged on a river bank through a sliding chute and is connected with a telescopic transmission mechanism; the telescopic transmission mechanism is connected with a power machine, then the outward telescopic movement of the dike body is implemented. The automatic telescopic water control spur dike has the advantages that the channel water level can be automatically adjusted, the navigation and flood control requirements of the rivers can be effectively met, the flood control protection of the dike body can be implemented, and the dike is applicable to the rivers with great water level change in flood and drought periods.

Description

technical field [0001] The invention belongs to the field of river management, and in particular relates to a retractable automatic water control groyne. Background technique [0002] A groyne is a hydraulic structure used for river regulation, because one end of it is connected to the river bank, and the other end extends into the water, forming a "D" shape with the embankment, so it is called a groyne. The main function of the spur dike is to protect the river bank from erosion caused by the direct erosion of the incoming flow. At the same time, it also plays an important role in improving the channel, maintaining the river facies and protecting the diversity of water ecology. In the 2014 government work report of the State Council, the development strategy of "relying on the golden waterway and building the Yangtze River Economic Belt" was put forward, which brought great opportunities for the development of my country's inland shipping industry. With the development of ...

Problems solved by technology

Although this form of spur dam has the advantages of simple structure and convenient construction, it also has the following disadvantages: (1) The navigation and flood control functions of the river often have certain contradictions. Structures are also vulnerable to flood damage

(2) The spur dam is a fixed building structure, which has limited function of water level adjustment, lacks self-adaptive adjustment ability, and cannot adjust the applicable water level according to the size of incoming flow
