Abstract

The utility model relates to a hydraulic automatic bidirectional swinging water gate comprising two controllable non-return valves which are oppositely installed. The non-return valve mainly comprises four rectangular main block plates which respectively make both inner ends of two piers of a water gate hole as the fixed rotation fulcrum and horizontally rotate between the center of the water gate hole and the lateral of the piers. The moveable sluice side of the two main block plates at the side of every pier can make rotatable connection with four or more blocks rectangular folded sheets. Two non top variable quantity containers formed on the soleplate of the water gate hole by two main block plates, more folded sheets, and a flank of the pier are two variable quantity abdominal cavities. The water gate has the two-way controlled non-return function, which decreases water gate building height by leaps and bounds. The unification of water gate and bridge broadens the deck channel, and the utility model can be conveniently operated with kinetic condition or not and raise the manufactured price ratio of the water gate.

Description

The flat sluice that revolves of waterpower automatic bidirectional

Technical field

The utility model relates to the sluice of a kind of hydraulic engineering, urban water supply and sewerage, relates in particular to a kind of pressure that utilizes water-head to form and impels that main gate-board is flat to be revolved mobilely, realizes damming and the novel sluice of automatic braking.

Background technology

The sluice overwhelming majority of traditional river, reservoir and feed ditch adopts the concrete component of landing gate, and the large-scale plant of traction gate lifting is installed on bridge floor, takies the bridge floor passage; The Ge Zhou Ba has been adopted to put down and has been revolved the gate of structure, and unidirectional two gates are 180 ° in conjunction with the angle, its gate driving mechanism complexity, and power consumption is big; Also having a kind of gate is to move as push-and-pull gate-type Horizon in the horizontal direction, but the lock hole count must not be greater than 2 holes.More than several sluice all have the manufacturing cost height, use inconvenience, only have the simple function that dams.

Summary of the invention

In order to overcome the shortcoming that prior art exists, the purpose of this utility model is in order to simplify the driving mechanism of sluice, reduce manufacturing cost, make things convenient for control water level, do not take bridge floor space, lock top, beautify the sluice contour structures, provide a kind of opposite opened two-way sluice, utilize waterpower to make that flashboard is automatically flat to be revolved mobilely, have the controllable bidirectional check function, be worthy of popularization.

The technical solution adopted in the utility model is: the flat sluice that revolves of waterpower automatic bidirectional is made up of two controlled one way stop peturn valves of installing relatively, mainly comprise four main rectangular flashboards, they are fixed rotary fulcrum with the inboard two ends of two gate piers of a hole sluice gate respectively, between center, lock hole and gate pier side, horizontally rotate, the rotatable connection done respectively with between four or the polylith rectangle folded sheet again in the mobile lock limit of two main gate-boards of each gate pier side, on the base plate of sluice gate, form by two main gate-boards, the polylith folded sheet, two no top variable containers, i.e. two variable abdominal cavities that gate pier one side is formed.

When two variable abdominal cavity volumes increase, order about two groups of corresponding main gate-boards and move until joining into two water shutoffs pushing up " people " font (less than 180 °) to flat the revolving in center, lock hole; When the abdominal cavity volume dwindles, order about two groups of corresponding main gate-boards and move until pressing close to the gate pier side full open to flat the revolving in gate pier side.

Two variable abdominal cavities are intercommunications, and two variable abdominal cavities all control whether need to connect the upper pond level or the level of tail water by pilot valve, realize the unlatching of main valve plate or close, and promptly upper pond level is connected in the abdominal cavity during barrier gate, cuts off the level of tail water; The level of tail water is connected in the abdominal cavity when opening a sluice gate, and cuts off upper pond level.Both had the function of damming, unidirectional check function had been arranged again simultaneously.

After adopting above technical scheme, the beneficial effect that the utility model reaches is: sluice has two-way controlled check function; Reduced the sluice building height significantly, the bridge floor passage has been widened in the unification of lock bridge; Have or not dynamic condition all to be convenient to operation, reduce energy consumption; Improved the cost performance that sluice is made.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

A kind of waterpower automatic bidirectional is flat to revolve sluice, comprises that mainly 2-4 pilot valve on four main rectangular flashboards, eight rectangle folded sheets and the both sides gate pier formed.Four main rectangular flashboards are fixed rotary fulcrum with the inboard two ends of both sides gate pier respectively also perpendicular to the pocket floor, between center, lock hole and gate pier side, horizontally rotate, two flashboards are the water shutoff of " people " font when damming, two flashboards move to the gate pier inside edge during unlatching, are that standard-sized sheet is logical until pressing close to abdomen border.2 rectangle folded sheets all are rotatably connected between the mobile lock limit of every main gate-board and gate pier medial surface.On the sluice gate base plate, form the variable abdominal cavity of forming by main gate-board 1a, folded

sheet

2a, 2b, 2c, 2d, main gate-board 1b and gate pier 6 sides, a no top 8, another variable abdominal cavity, no top variable abdominal cavity, 9, two no

tops

sheet

2e, 2f, 2g, 2h, main gate-board 1d and gate pier 7 sides.The fulcrum of every main gate-board, folded sheet and gate pier medial surface junction is fixed axis point of

rotation

4a, 4b, 4c, 4d, 4e, 4f, but the joint shaft of junction is translation point of

rotation

5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h between every main gate-board and folded sheet junction, the folded sheet, so main gate-board 1a, 1b with fixedly point of rotation 4a, 4b be the center of circle to 4e point direction translation rotation, same main gate-

board
