Problems solved by technology

[0002] Most of the sluices of traditional rivers, reservoirs and irrigation canals are concrete components with lifting gates, and a large device for pulling and lifting the gates is installed on the bridge deck, occupying the bridge deck passage; The combination angle of the gate is 180°, the gate driving mechanism is complex, and the power consumption is large; there is also a gate that translates in the horizontal direction like a sliding door, but the number of gate holes must not exceed 2
All of the above types of sluices have high manufacturing costs, are inconvenient to use, and only have a single function of damming

Embodiment 1

[0015] Let M 1 water level above M 2 At water level:

[0016] 1. Request to open the gate. Close the pilot valves 3a, 3c, open the pilot valves 3b, 3d, at this time the abdominal cavity is connected to M 2 low water level, M 1 The water level is higher than the water level of the abdominal cavity, so that the main gates 1a, 1c are opened, and the hydraulic force pushes the folding plates 2c, 2d, 2g, 2h to move, so that the main gates 1b, 1d are opened until they are fully opened. Controlling the closing degree of the pilot valves 3a and 3c can also change the opening degree of the main ram.

[0017] 2. Request to close the gate. Close the pilot valves 3b, 3d, open the pilot valves 3a, 3c, then M 1 The high water level in the direction enters the abdominal cavity, so that the main rams 1a and 1c are automatically closed until the two main rams are butted to seal the water.

Embodiment 2

[0019] Let M 2 water level above M 1 During the water level: its operation steps are opposite to embodiment one.

Embodiment 3

[0021] Directional non-return is required. The initial setting is to close the pilot valves 3a, 3c, and open the pilot valves 3b, 3d. Then M 1 The ram opens automatically when the water level is high; M 2 When the water level is high, the gate is automatically closed, which acts as a one-way check. If it is reversed, the result is opposite.

Abstract

The invention relates to a waterpower automatic bi-direction flat-revolving water brake made up of two controllable unidirectional check valves oppositely equipped. It mainly includes four rectangle main gate boards which make the two ends at the inside of the pier as the fixed revolving pivot, and flat-revolving between the center of sluice opening and the side of the pier. Four or more rectangle folded boards are revolving connected to the boarder of moving brake of the two main gate boards on each side of the pier. Two topless variable quantity containers are formed at the base plate of water gate by two main gate boards, plural folded boards and one side of pier. The water brake has the function of bi-direction controllable non-return, and sharply decreases the construction height of the water brake. Brake and bridge joined together widens the passage of the bridge floor. No matter whether it has the driving condition can be conveniently to be operated. And the performance price ratio of the water brake manufacturing is increased.

Description

technical field [0001] The invention relates to a sluice for water conservancy projects and urban water supply and drainage, in particular to a new type of sluice which utilizes the pressure formed by the water level difference to drive the main ram to move horizontally to realize interception and automatic non-return. Background technique [0002] Most of the sluices of traditional rivers, reservoirs and irrigation canals are concrete components with lifting gates, and a large device for pulling and lifting the gates is installed on the bridge deck, occupying the bridge deck passage; The combination angle of the gate is 180°, the gate driving mechanism is complex, and the power consumption is large; there is also a gate that translates in the horizontal direction like a sliding door, but the number of gate holes must not exceed 2. The above several sluices all have high manufacturing cost, inconvenient use, and only have a single function of damming. Contents of the inven...
