Abstract

The invention discloses a door-in-door type gate in the field of gates, which comprises a gate body blocked on a river channel, a bottom sill is provided under the gate body, gate grooves are provided on both sides of the gate body, and the backwater side of the gate body is provided with There is a beam, and a hydraulic cylinder for lifting the door body is installed upright under the beam. A plurality of diversion pipes are arranged at intervals in the door body. The lower end of the diversion pipe is connected with an electric control valve, and the inlet of the electric control valve is located on the water-facing side. ; The outlet at the upper end of the draft pipe is located on the backwater side. The door body can be lifted or lowered by the hydraulic cylinder to realize the function of blocking and discharging water. When necessary, the electric control valve can also be opened to make the water flow from the upstream side through the diversion pipe to the backwater side. Under certain circumstances, the water spray on the backwater side can form a landscape effect. The device is easy to open and close, has fewer auxiliary buildings and is easy to maintain, and has a landscape effect.

Description

technical field [0001] The invention relates to a water conservancy facility, in particular to a lifting gate. Background technique [0002] With the expansion of city scale and the sudden increase of urban population, water consumption is increasing, and the uneven distribution of water resources in our country requires comprehensive dispatching and management; with the increase of comprehensive environmental management and water environment improvement, and urban construction In order to meet the needs of the landscape, various new gates have emerged as the times require, such as lying doors, flap doors, one-word doors, rising doors, bottom pivoted flap doors, etc. The above-mentioned first four kinds of doors all need hoist buttresses, and the amount of civil work is large, while the lifting door also needs a working bridge and a hoist room, and the civil work load is even greater. Difficult to maintain. The existing gates do not have a landscape function when transferr...
