Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] As shown in the embodiment shown here,

[0023] By setting on the river channel and temporarily closed, the liquid level in the dam can be effectively controlled, so that when the ship passes through, the liquid level can be appropriately reduced by means of diversion, so that the ship can pass through the liquid stably. In places with a large height difference, the hull can smoothly pass through the river sections with large slopes; at the same time, through the diversion control of the pump body, the liquid between the descending section and the discharge section in the dam can flow with each other. During the opening and closing, the liquid can be effectively regulated, which is convenient for the rapid passage of the hull; at the same time, through the control of the upper and lower gate valves, the passage of the hull can be effectively matched wi...

Abstract

The invention relates to the field of water conservancy construction, in particular to an automatic lifting retaining dam utilizing hydraulic power, which comprises a river coastal bank, a capital construction dam body seat and a plurality of gate baffle frames, the capital construction dam body seat is arranged in the river coastal bank, and the gate baffle frames are uniformly arranged in the capital construction dam body seat. And the plurality of gate baffle frames form a descending section and a discharging section on the infrastructure dam body seat. The descending interval is close to a high liquid level, and the discharging interval is close to a low liquid level; an operation table convenient to operate is fixed in the infrastructure dam body seat, and two switching circulation holes allowing liquid to flow are formed in the operation table; the descending intervals are communicated with each other through the switching circulation holes; the discharge sections are communicated with each other through the switching circulation holes. Two combined pipeline gate valves for preventing backflow are fixed in the operation table, and two combined pipeline gate valves are fixed on the switching circulation hole; the ship has the beneficial effect that the ship body can stably and safely pass through a high-fall section of a river channel.

Description

technical field [0001] The invention relates to the field of water conservancy construction, in particular to the automatic lifting and lowering of a dam by hydraulic power. Background technique [0002] It is usually convenient for the application of water conservancy in the position with a large river drop, and the corresponding dam is built for the implementation of the water conservancy project. At the same time, the corresponding dam is built to facilitate the passage of the hull; The latitude-to-high-latitude river section is an environmentally friendly dam. In view of the problem that the traditional thick ice layer near the dam cannot be bombed, it will cause secondary ice to block the river again when the night comes. The following solutions are now proposed, including liquid level and arc The side of the dam body close to the liquid surface is close to the top end with an extension plate fixed by bolts, and the middle of the upper surface of the extension plate is ...
