Abstract

The invention provides a foldable gate. The foldable gate is flexible in operation and easy to operate. The foldable gate is composed of a plurality of foldable gate leaves, a gate pier, a gate starting device and a gate storing device, wherein the gate leaves, the gate pier, the gate starting device and the gate storing device are hinged to one another. The gate is formed by connecting the multiple gate leaves in a hinged mode. When the gate is opened and does not stop water, the gate is folded and placed in the gate storing device which is arranged in a gate bottom plate, the gate is not exposed in a river and water can flow smoothly and freely. When the gate stops water, the gate starting device lifts up the gate, the gate leaves are unfolded from the folded state, so that an integrated water-stopping gate is formed, and the water level is increased. The foldable gate is easy and convenient to operate.

Description

Folding gate

Technical field

The present invention relates to a kind of water conservancy projects, belong to hydraulic engineering-sluice.

Technical background

In China's middle and small river, reservoir and irrigated area prior art, widely used have panel turnover sluice gate, convenient steel dam and a common gate installed, and panel turnover sluice gate dash can meet the demands, but the phenomenon that also blocks water after opening flood period, and alluvial and winter be freezing also has impact to gate; When rotation steel dam is freezing in the north dry season, together with steel dam can freeze with river bed; Common gate can be avoided the shortcoming of front two engineerings, but it is large after gate opening, to take up room, and opens and closes framed bent attractive in appearance not in landscape engineering.

Folding gate both sides arrange gate pier, consistent with common gate effect while closing dash, gate is not placed in the gate storing unit in gate floor after folding when dash, and position of strobe is lower than river bed, even if take up room, be also little ice period below ice sheet, avoid gate freeze with river bed together with phenomenon.

Fold after gate dash operation a period of time, have alluvial before lock, while needing starting gate, can first will carry unlatching certain altitude flood period on gate, and sand washing is opened gate storing unit after becoming silted up again, and gate is folding to be taken in it.After gate opening, in river course, can't see gate, current are unimpeded arbitrarily, effectively solve the front alluvial of lock and the phenomenon that blocks water flood period.

Summary of the invention

Folding gate takes up room after greatly dwindling gate opening, reduces the tall and big keying facility of common gate, improves the freezing impact on view lock in the north.

Folding gate is made up of the folding gate flap being articulated and connected, gate pier, gate starting drive, gate storing unit.When folding gate opening, hinged gate flap folds, minimizing takes up room, and be placed in gate floor inner gate storing unit, there is with bottom gate flap the transverse axis being connected with gate starting drive at folding gate top, starting drive is mentioned after gate, affected gate is flattened by upper and lower two transverse axis, gate forms sealing with left and right and the bottom waterstop of doorframe after slideway moves to permanent position, starts gate slot place steel arm and is fixed gate.

Gate dash a period of time, pocket floor forms certain alluvial, when gate is packed up, should first unclamp steel arm, upwards starts gate opening certain altitude, pocket floor alluvial is washed away, then open pocket floor gate storing unit and pack up folding gate.

Gate storing unit is positioned at gate floor, has taken gate floor certain space, should suitably thicken gate floor for ensureing that gate floor is stable.

Folding lock gate leaf is arranged in upstream, doorframe sealing is arranged in downstream, and after gate starts expansion, upper water pressure energy plays the effect of power-assisted sealing sealing, and steel arm is to gate externally applied forces by gate pier, ensure that the gate after launching is open and flat indeformable, and play the effect of fixed gate reinforcement sealing.

The folding hinged gate flap of gate is hinged not to be required airtightly, only rise and connect turning effort, but sealing must be installed in the hinged limit of gate flap, ensure folding gate launch after between every fan gate flap in conjunction with tight, be complete dash facility.And sealing is installed detachable.

Folding gate installation is between gate pier, and gate doorframe, slideway, steel arm are arranged in gate pier, and gate pier height is that normal water retaining position adds superelevation, and meeting gate has and necessarily upwardly open height, facilitates sand washing.

Folding lock not used time hinged door leaf folds, and minimizing takes up room, and in northern low water frost region, even if freeze river bed, gate is embedded in also can be comparatively safe under ice sheet.If the more river of silt particle, gate is folding to be placed in gate storing unit, can reduce silt particle infringement.

At the folding gate of reservoir and irrigated area application, can regulate and control more flexibly water level, can avoid that overproof flood occurred common gate in the past time, open and close the obstruction of facility to high water level, to the adverse effect of engineering.
