Description
Technical field
The present invention relates to a kind of valve system, in particular to a kind of valve system for rotating water blocking.
Background technique
A kind of bidirectional turning gates of segmental shape is disclosed in Chinese patent database library, application number:
CN201320472037.5；The applying date: 2013-08-02；Publication number: CN203420260U；Publication date: 2014-02-05,
Structure includes civil engineering structure, arc gate door body, supporting mechanism, hydraulic cylinder and ground sill, and civil engineering structure is set to the arc gate door body
Arranged on left and right sides, ground sill is set to the lower section of the arc gate door body, and supporting mechanism is fixedly connected with the arc gate door body, and
Hinged with the civil engineering structure, the hydraulic cylinder level is fixed on the civil engineering structure, piston rod and the supporting mechanism
Hingedly.Sluice gate body in the device can downwardly turn over unlatching under the driving of hydraulic cylinder, open rear arc sluice gate body and be located at the water surface
Hereinafter, without any equipment or structures above the water surface, and ensure that the water surface is penetrating, do not influence landscape and navigation；It can also basis
It needs to be flipped up unlatching, opens rear arc sluice gate body and expose the surface, easy access maintenance.Disadvantage is that: the device
Ground sill on be provided with arc groove with gate mates, which be easy to cause sediment siltation in the bottom in river, leads
It causes knife switch to be obstructed, or even directly results in gate deformed damaged.
Summary of the invention
The object of the present invention is to provide a kind of anti-silting rotation backwater gate, allows to avoid sediment siltation, guarantee gate
Using relatively reliable.
The object of the present invention is achieved like this: a kind of anti-silting rotation backwater gate, the lock wall including the setting of river two sides,
Bottom of river channel is provided with bottom plate, and river at least side is provided with headstock gear, the sluice gate body for blocking water, sluice gate body are equipped in river
Both ends are equipped with rotating arm, and rotating arm is rotatably supported on lock wall through shaft, the piston rod extension end of headstock gear and the rotating arm
It is hinged, the bottom plate includes high plane and low level face, and arcwall face, arcwall face and lock are equipped between the high plane and low level face
Door body matches, and the least significant end of the arcwall face is not less than plane where low level face.
When the invention works, sluice gate body can be driven to rotate by headstock gear, realizes that sluice gate body rise is blocked water and fallen and discharges water,
Silt, stone, trees in the incoming flow of upstream etc., can be directed across sluice gate body bleed downstream, will not be in the arc on bottom plate
Shape face position is accumulated, so as to avoid gate card resistance.Compared with prior art, the present invention, which has, uses reliably, can be voluntarily
The technical effect of dredging.
As a further improvement of the present invention, at least one support pier can be set in the middle part of river, and support pier is equipped with
Free bearing is supported, support arm is correspondingly provided on sluice gate body, is hinged between support arm and support free bearing.By multi-point support, so that
The device can be used for broader river.Certainly, for relatively narrow river, support pier can also be not provided with.
To be further reduced a possibility that product is become silted up, it is connected between the arcwall face and low level face through inclined surface.Mud can be with
It trickles for the downstream along inclination, thus siltation can be further reduced.
To guarantee that manufacturing cost is low, stress is more scientific, the sluice gate body sail shape narrow in bottom wide upper portion.Its into
The improvement of one step is that the back side of the sluice gate body is a flat surface, and when sluice gate body is preferably minimized position, the back side of sluice gate body is from leaning on
Nearly high one lateral low level face side of plane inclination.The structure, which may further ensure that, will not accumulate silt at the sluice gate body back side.
To prevent leak, it is respectively equipped with only between the sluice gate body bottom and arcwall face, between sluice gate body both ends and lock wall
Watertight seal.
In order to which sluice gate body is fixed on specific position, the rotating arm is equipped with for locking rotating arm and lock wall
Lock hole.Rotating arm and the fixture on lock wall or lock wall can mutually be fixed by lock hole, to reach locking sluice gate body
Purpose.
A further improvement of the present invention is that the front of the sluice gate body is the cambered surface to match with arcwall face.The two it
Between can form mutually matched face, it is possible to reduce sediment siltation space guarantees that movement is reliable.Certainly, sluice gate body does not limit to
In the shape, it is also possible to the face of other shapes.
It is as a further improvement of the present invention, gear silt plate is equipped between the high plane and sluice gate body bottom, it can be with
It is connected by the articulation piece that high plane side is arranged with the gear silt plate.It keeps off silt plate to be arranged along river width direction, in sluice gate body
When standing, the sundries such as mud, rubble, branch in water flow can be blocked in high plane side, and when sluice gate body fell, this
A little sundries can cross sluice gate body and downstream flow away, and the program can effectively avoid sundries and be caught between sluice gate body and arcwall face.Lock
When door body normal switch, gear silt plate will not influence the normal rotation of sluice gate body.
