Embodiment Construction

[0015] 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:

[0016] This embodiment describes a normally open overflow drain gate structure, such as figure 1 As shown, it 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 prefabricated part similar to a channel steel structure, and of course it can also be made of steel. For the sake of structural strength, it is preferable to arrange a structural cavity similar to a cabin at the bottom of the base 12 . 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 aforementio...

Abstract

The invention provides a normally-open overflow drainage sluice structure. A sluice valve of the normally-open overflow drainage sluice structure comprises a central sluice plate and two sliding sluice plates disposed on the two side of the central sluice plate. The two sliding sluice plates extend out in the width direction of a base respectively. A rod shaped like a walking stick is horizontallydisposed in each sliding sluice plate and is in horizontal sliding fit in the sliding sluice plate. A handle section of each rod inclines towards the upper side of one side of the central sluice plate and is connected with a traction rope. The two traction ropes on the two sides are each wound around a tensioning wheel to be tied onto a reset mechanism that is disposed at the upper end of the central sluice plate. A rope winding device of each reset mechanism comprises two friction rings, a plurality of friction pieces and an air bag, wherein the friction rings are connected with the corresponding traction rope, and when sluice pieces are completely pulled into installing holes where the sluice pieces are located, the friction rings and the air bag rotate relatively. The normally-open overflow drainage sluice structure can be rapidly installed and constructed at a riverway outfall to resist large water flow impact, and the normally-open overflow drainage sluice structure has flexibleand selectable working mechanism and high adaptability.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and more specifically relates to a normally open overflow drainage gate structure. 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 the versatility is weak. However, in the current drainage and flood discharge based on the main river bas...
