Description
Technical field
The utility model is related to a kind of urban underground water drainage pipe current-limiting mechanisms, belong to Municipal water-proof drainage system engineering
Field.
Background technology
In present Chinese city underdrainage system, generally spliced using many drainpipes, it is multiple to be formed
Miscellaneous Buried Pipeline Network Systems；And there are countless branch branches in pipe network system, after rainwater enters Buried Pipeline Network Systems, due to
The water flow upper limit all same of each branch, therefore flow, when reaching at shunting, rainwater is often more to geographical location
Lower side branch shunts, rather than enters the branch shunting in river to faster outflow Buried Pipeline Network Systems；It is easy to cause in this way
The low branch hydraulic pressure in geographical location is excessive, and then reversely sprays water after the low inspection shaft in part geographical location.
Utility model content
The purpose of this utility model is that solving the above problems, the utility model is devised, passes through restricted part buried pipe
The branch line flow of road system, makes the water flow in branch line after reaching a certain level, to the water in the branch line
Flow is limited, to make flow flow into the low pipeline in geographical location from preferred path outflow pipe-line system is non-preferential
In.
Technical solution adopted by the utility model to solve its technical problems is：
The utility model discloses a kind of urban underground water drainage pipe current-limiting mechanism, frame body and movable part, and frame body is fixed on draining
On pipe madial wall, movable part is hinged at the top of movable part；Movable valence includes current limiting plate and clump weight；Current limiting plate and clump weight difference
Positioned at the both sides of hinged place and the center of gravity of movable part is positioned at close to the side of clump weight, and the influent side that current limiting plate is located at drainpipe makes
It can increase the area met to flow under the promotion of flow.
Using above structure, when the water level in drainpipe is reached at current limiting plate, water jet propulsion current limiting plate moves down, to make
The flow into the drainpipe is hindered using flowing plate, and then influences the previous branch crossing shunting of this section of drainpipe, reducing should
The water flow of section drainpipe excessively causes the probability that the water of rear side is overflowed from catch pit port.
Further, it is provided at least a horizontal lever, lever on frame body and is used to support the back side of current limiting plate.The knot
Structure can reinforce the supportive of current limiting plate by lever, and then improve the structural strength of the service life and the present apparatus of current limiting plate.
Further, it is equipped with rotation seat at the top of frame body, rotation seat is equipped with rotatable rotation axis；Clump weight and current limliting
Plate passes through counterweight connecting rod and connecting rod and rotation axis connection respectively.By rotation axis in the structure, the freedom of structure can be realized
Rotation when not up to, can utilize the structure to realize limiting plate to the memory flow current limliting when water flow reaches setting value
Reset.
Further, when lever support current limiting plate, current limiting plate is perpendicular to water (flow) direction.By the design in vertical water conservancy direction,
The area that can make full use of current limiting plate realizes maximum water flow limitation.
Further, the counterweight connecting rod and connecting rod are in 90 degree of angles.The structure can fully realize clump weight and limit
The cooperation of plate ensures the optimization of the two relative position.
Further, the frame body is the ring-type of lower opening；The madial wall of frame body fitting drainpipe simultaneously passes through fixing screws
It is fixed.For the structure due to the structure using split ring, being frame body has certain shrinkage, can be convenient in insides of pipes
Installation, while the structure being made more to be bonded the side wall of drainpipe；Improve structural strength and service life.
Further, the area of the current limiting plate end face is a quarter of drainpipe area of section to 1/6th.It should
Structure needs to calculate required limitation flow when current limliting plate suqare is chosen, at the same will also in pipe network system everywhere
Shunt position is calculated, and to select shunt volume appropriate, the rainwater pressure to ensure this section of rear end is relatively low.
Further, when non-water flow pushes, on the downside of current limiting plate away from four that the distance at the top of drainpipe be draining pipe diameter/
1/1st to five.The need of the height of the current limiting plate are by calculating, and by depending on actual demand.
Further, the current limiting plate is rectangular, round or arc-shaped.
The beneficial effects of the utility model are：
1, the branch line flow by restricted part subterranean pipe line system of the present apparatus, makes the water flow in branch line
After reaching a certain level, the water flow in the branch line is limited, to make flow be flowed out from preferred path
Pipe-line system and non-preferential flow into the low pipeline in geographical location；
2, this structure is simple in structure, easy to install and use, can be transformed, push away to existing Urban Buried Pipeline Network Systems
Wide property is good, and this is simple in structure, of low cost, can effectively reduce the problem hair that hydraulic pressure is too strong in the low pipeline in geographical location
It is raw.
