Detailed Description

The following is combined with the attached drawings. The present invention is further explained.

Before the scheme is installed, two civil engineering bases 1 are constructed at the closure position of a river channel or a pipe duct; the two civil engineering bases 1 are respectively positioned at two sides of a river channel or a pipe canal, and the sinking gate is arranged on the civil engineering base 1.

As shown in fig. 1, the sink gate includes a door frame 2, a cover plate 3, a hydraulic cylinder 4, and a door panel 5. Wherein, the door frame 2 is in a concave shape, has an upward opening, and is fixed on the civil engineering base 1. The cover plate 3 is fixed on the top of the doorframe 2.

With reference to fig. 1 and 2, a hydraulic cylinder 4 and a door plate 5 are arranged in the door frame 2; and the hydraulic cylinder 4 is connected with the door panel 5 and can drive the door panel 5 to slide up and down.

The specific structure in the door frame 2 is shown in fig. 3-5, and the door frame 2 includes a side cover plate 21, a supporting framework 22, a bottom frame 23 and a panel 24; the bottom frame 23 is rectangular, and the door panel 5 passes through the bottom frame 23. The side cover plates 21 are vertically arranged at two ends of the bottom frame 23; the two panels 24 are vertically installed in the middle of the front and rear surfaces of the bottom frame 23. The supporting framework 22 is installed in the side cover plate 21, and the supporting framework 22 is arranged in parallel from top to bottom in an equidistant manner. The hydraulic cylinder 4 penetrates the support frame 22 in the side cover 21 from top to bottom. The hydraulic cylinder 4 comprises a cylinder body 41 and a piston push rod 42, and the bottom of the cylinder body 41 is fixed on the cover plate 3; the piston push rod 42 is fixedly connected with the side surface of the door panel 5.

A longitudinal sliding groove 7 is formed in the door frame 2, the longitudinal sliding groove 7 is fixed on the supporting framework 22, and the door plate 5 is arranged in the longitudinal sliding groove 7; so that the piston rod 42 can pull the door panel 5 to slide up and down along the longitudinal sliding groove 7, and when the piston rod 42 is retracted into the cylinder 41, the door panel 5 just blocks the concave-shaped opening of the door frame 2.

As shown in fig. 6, a hydraulic cylinder avoiding opening 221 is formed in the middle of the support frame 22, and the hydraulic cylinder 4 passes through the hydraulic cylinder avoiding opening 221.

In addition, a plurality of design openings 222 are further formed in the support frame 22, and the design openings 222 can reduce the weight of the support frame 22.

In addition, as shown in fig. 1 to 5, in order to maintain the door panel 5 in a vertical state after installation; the inventor is provided with a plurality of perpendicularity adjusters 6 on the door frame 2, and by adjusting these perpendicularity adjusters 6 are equidistantly distributed along the opening edge of the door frame 2.

In addition, the cover plate 3 at the top of the door frame and the door frame 2 are both internally provided with sealing gaskets, thereby realizing the function of throttling sealing.

The working process of the invention is as follows:

when the hydrological conditions in the river channel or the pipe canal meet the flushing conditions, the electric control system acquires signals and gives corresponding instructions to the hydraulic station. The hydraulic station is started to drive the hydraulic cylinder which is in an extending state for a long time (ensuring that a waterway of a river channel or a pipe canal is smooth) to retract, so that the gate plate rises to cut off the waterway to start water storage. When the water demand is enough, the electric control system gives an instruction, the electromagnetic valve of the hydraulic station is reversed, and the hydraulic cylinder extends out. The river or canal is flushed.

The invention can also realize the function of throttling and sealing the pipe duct with the closed top.
