Abstract

The present invention relates to an automatic hydraulic bidirectional swinging water gate which is composed of two controllable one-way non-return valves which are oppositely installed. The water gate mainly comprises four rectangular main gate plates which respectively use both inner ends of two gate piers of a hole gate opening as fixed rotation fulcrums and horizontally rotate between the center of the gate hole and the side surface of each gate pier, wherein the moveable gate sides of the two main gate plates at the side surface of each gate pier can are rotationally connected with four or a plurality of rectangular folding plates. Two containers with variable quantity and without tops, which are two abdominal cavities with variable quantity, are formed on a soleplate of the gate opening by two main gate plates, the folding plates, and one side surface of the gate pier. The water gate has a non-return function in a two-way controlling mode, and has the advantages that the building height of the water gate is decreased greatly, a passage on the bridge surface is widened because of the combination of the water gate and a bridge, and the water gate can be conveniently operated no matter whether the kinetic condition is provided or not. Thus, the manufactured price ratio of the water gate is improved.

Description

The flat sluice that revolves of waterpower automatic bidirectional

Technical field

The present invention relates to the sluice of a kind of hydraulic engineering, urban water supply and sewerage, relate in particular to a kind of pressure that utilizes water-head to form and impel that main gate-board is flat to be revolved mobilely, realize 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 objective of the invention 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 used in the present invention 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 the folded sheet that is made of four or polylith rectangular slab 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 rectangular slab, 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 present invention 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 invention will be further described 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 8,9 bottom intercommunications of forming by main gate-board 1c, folded 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 1c, 1d are so that fixedly point of rotation 4c, 4d are that the center of circle rotates to the translation of 4f point direction.

Embodiment one

If M ₁Water level is higher than M ₂During water level:

1, requires to open sluice gate.Close pilot valve 3a, 3c,

open pilot valve

3b, 3d, at this moment M is connected in the abdominal cavity ₂Low water stage, M ₁Water level is higher than the abdominal cavity water level, and main gate-board 1a, 1c are opened, and waterpower promotion folded sheet 2c, 2d, 2g, 2h move, and main gate-

board

1b, 1d are opened until opening fully.Control the turndown ratio of pilot valve 3a, 3c, also can change the open degree of main gate-board.

2, require to close sluice gate.

Close pilot valve

3b, 3d, open pilot valve 3a, 3c, at this moment M ₁The high water level of direction enters the abdominal cavity, and main gate-board 1a, 1c are closed automatically, until two main gate-boards butt joint water shutoff.

Embodiment two

If M ₂Water level is higher than M ₁During water level: its operating procedure is opposite with embodiment one.

Embodiment three

Require directed non-return.Just set and close pilot valve 3a, 3c, open pilot valve 3b, 3d.M then ₁Flashboard is opened automatically during high water level; M ₂Flashboard cuts out automatically during high water level, plays unidirectional non-return effect.If anti-the setting, then the result is opposite.
