Embodiment Construction

[0017] In order to make the technical means, creative features, goals and functions achieved by the present invention clearer and easier to understand, the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments:

[0018] This embodiment describes a normally open overflow drain gate structure for medium and small flows, which mainly includes a base 12 for drainage and a gate valve inserted into the base 12 in a cut-off manner. The base 12 can be poured with concrete to form a similar The prefabricated part of the channel steel structure can also be made of steel, of course, a structural cavity similar to a cabin should be arranged at the bottom of the base 12 due to the need for structural strength. According to needs, it is installed somewhere in the drain outlet, and the receiving beam 13 is fixed on the top of the base 12 along its width direction. The space below the receiving beam 13 is the aforementioned st...

Abstract

The invention provides a normally open overflow drainage sluice structure for small and medium flows. A sluice valve comprises a central flashboard and two sliding flashboards installed on the two sides of the central flashboard, the bottoms of the central flashboard and the sliding flashboards are provided with a plurality of comb-shaped fixed sluice pieces arranged at intervals. the sides, facing the central flashboard, of the sliding flashboards each are provided with a strip-shaped inserting part, and the other sides of the sliding flashboards are inserted into guide grooves; the insertingparts are inserted into inserting holes in a sliding fit mode, the two sliding flashboards each extend out in the width direction of a base so that sliding sluice pieces which extend out of the inserting holes and in the inserting parts can be automatically popped up downwards; and a friction ring of a winding device is connected to the other end of a traction rope, a circle of friction groove isformed in the inner wall of the friction ring in the circumferential direction thereof, the end, with abrasive resistance, of a friction piece is located in the friction groove and is in close contact with the friction groove, and the other end of the friction piece is fixedly connected to the surface of an air bag. According to the structure, rapid installation and construction of a drainage sluice of a river channel water outlet can be realized, the water drainage amount can be adjusted, and the adaptability is strong.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and more specifically relates to a normally open overflow drainage sluice structure for medium and small flows. Background technique [0002] Drainage sluices are used for flood discharge and drainage in water conservancy projects, and some of the river outlets are usually opened so that water can flow out freely during the rainy season and flood season to avoid embankment bursting and other situations. Most of the current drainage sluices use one or several rams to cut off the water outlet, and select to open or close some rams according to needs to adjust the flow for normal water storage, and each ram can work independently , they are all installed independently during installation, and installed one by one at the water outlet of the channel, river or lake. It needs to be customized from time to time, and its versatility is weak. At present, in the small and micro water conservanc...
