[0002] With the rapid development of my country's water conservancy, more and more river management and river landscape projects have emerged. In order to solve the contradiction between blocking the river and river navigation, the research of small ship lifts is imperative. The traditional ship lift has a cumbersome structure, more equipment, high cost, and more complicated operation. It is a waste for waterways with small drop. Therefore, if there is a gate system that can effectively cut off the water and can be filled with water by itself, the structure of the ship lift can be simplified and replace the traditional ship lift. While meeting functional requirements, it can maximize cost savings and simplify operation, which is of great significance to the construction of a large number of river management and river landscape projects.

The gate has a simple structure, can effectively block the upstream and downstream water flows, and can reduce the scouring of civil engineering foundations during water filling by filling itself and the flushing energy dissipation during water filling, and can meet the task of lifting and passing ships in small-drop waterways.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See Figure 1-6 A gate that can be used for flushing and filling with water includes a waterway 1. Both sides of the middle part of the waterway 1 are concave structures. A door frame 2 is fixed between the two concave structures. The bottom of the door frame 2 is a convex structure facing upstream. A gate 3 is rotatably connected to the door frame 2. Water level monitors 4 are respectively provided on the waterway 1 on both sides of the gate 3. The two water level monitors 4 are used to monitor the water level difference on both sides of the gate 3. A hydraulic gate hoist 5 for controlling the opening and closing of the gate 3 is provided at the top of the waterway 1. A control room 6 is provided on one side of the top of the waterway 1. A controller 7 is provided in the control room 6. The driving circuits of the two water level monitors and the hydraulic gate hoist 5 are respectively connected to the controller 7. Water passing mechanisms 8 are provided on both gates 3.

[0021] The preferred door frame 2 includes a bottom frame 22 of a V-shaped structure and two side frames 21 vertically arranged at both ends of the bottom frame 22. The bottom frame 22 and the side frames 21 are provided with ribs 24 and tie bars 25 on the downstream sides. The ribs 24 and tie bars 25 can be used to better fix the bottom frame 22 and the side frames 21 to the bottom and two side surfaces of the waterway 1. The bottom and top of the two side frames 21 are respectively provided with a bottom support seat 27 and a bolt seat 26. The bottom support seat 27 is fixed to the bottom surface of the waterway 1. One end of the bolt seat 26 is fixed to the side of the waterway 1 and the other end is fixedly connected to the side frame 21. The side of the gate 3 is rotatably connected to the bottom support seat 27 and the bolt seat 26.

[0022] Preferably, the door frame 2 is welded with a water-stop seat plate 23 toward the upstream side, and the bottom end and the opposite side of the gate 3 are connected with a water-stop sealing structure 9, so that when the gate 3 is closed, it can be in a sealed state, thereby sealing the water flow upstream and downstream.

[0023] The preferred gate 3 is composed of an upstream panel 31, a downstream panel 32 and a beam structure 33. The side walls of the gate 3 are provided with a bolt 34 and a bottom support 35. The bolt 34 and the bottom support 35 are rotatably connected to the bolt seat 26 and the bottom support seat 27 respectively. A lifting ear structure 36 is provided on the top of the gate 3. The piston rod of the hydraulic opening and closing machine 5 is rotatably connected to the lifting ear structure 36. A water hole 37 is horizontally opened on the upstream panel 31 and the downstream panel 32.

[0024] The preferred water flow mechanism 8 includes a water filling pipe 81 and an electric valve 82. The water filling pipe 81 is arranged in the water flow hole 37, and the electric valve 82 is arranged in the water filling pipe 81. The driving circuit of the electric valve 82 is connected to the controller 7 through an electric wire. The opening and closing of the electric valve 82 is controlled by the controller 7 so that the upstream water flow can fill the downstream.

[0025] The working principle of the present invention is as follows: when a ship needs to pass downstream, the controller 7 first controls the electric valve 82 to open the water filling pipe 81 to unblock the water filling pipe and fill the downstream with water. As the water level in the downstream gradually rises, when the water level monitors 4 on both sides of the gate 3 detect that the upstream and downstream water levels are consistent, the two hydraulic gate operators 5 on the top of the waterway 1 are controlled by the controller 7 to work, wherein the piston rods of the two hydraulic gate operators 5 respectively pull the gate 3 to open the gate 3, so that the upstream and downstream are connected, and the ship can pass through at this time. After the ship passes, the controller 7 controls the hydraulic gate operator 5 to start and close the gate 3, and then controls the electric valve 82 to close the water filling channel 81. Among them, the two sides of the middle part of the waterway 1 are set as a concave structure and the door frame 2 is set as a convex structure facing upstream. When filling with water, the jet water can be used to offset and dissipate energy, which can reduce the scouring of the civil engineering foundation during filling with water.
