Description
Technical field
This utility model belongs to hydraulic engineering field, specifically a kind of Suction Type Shaft spillway.
Background technology
Affected by many factors such as geological conditions, surroundings, for the medium and small reservoirs irrigating, generate electricity often by excessive flood
Road is designed to shaft spillway, and when in storehouse, water level exceedes design flood level, water flows through shaft spillway and no presses flood discharge, lets out
Big vast speed is slower, and when running into check flood, reservoir area is carried out the water yield and is more than letdown flow, and water level continues to rise close to check flood level,
Although check flood level belongs to interim design water level, utilize the storage capacity water-retention to check flood level for the design flood level, water
Storehouse is still safe, and when the water yield is carried out less than letdown flow in reservoir area, water level falls after rise to design flood level, i.e. reservoir maximum effective storage
For the following storage capacity of design flood level.If vertical shaft water inlet absolute altitude is carried to check flood level, when reservoir area water is more than lower earial drainage
During amount, water level continues to rise, and because conventional shaft spillway is overflow flood discharge, flood discharge speed is slow, there is unrestrained dam and collapses the danger in storehouse
Danger, for conventional shaft spillway, this by improving vertical shaft water inlet absolute altitude, using design flood level to check flood level it
Between storage capacity water-retention method inadvisable.Design flood level to check flood phase difference is not very big, but cuts open because reservoir area is vertical
Face is gentle slope funnel-form, and it is even up to a million that the storage capacity between design flood level to check flood level is likely to be breached tens of thousands of, hundreds of thousands
Cubic meter, this Partial security storage capacity is not utilized effectively, and causes very big waste.
Utility model content
In order to solve above-mentioned technical problem present in prior art, this utility model provides a kind of Suction Type Shaft and overflows
Big vast road, by curved under curved cylinder under basis, hoistway wall, vertical shaft, flood-discharge tunnel, flood-discharge tunnel wall, flood-discharge tunnel tail lock, siphon, siphon
Cylinder horn mouth, curved cylinder dome, bracing frame composition under siphon, curved under curved cylinder horn mouth under curved cylinder under described siphon, siphon, siphon
Cylinder dome is fixedly installed for one integrally, is made of stainless steel.
Further, described bracing frame one end is fixedly installed with cylinder curved under siphon, and the other end is fixedly installed with hoistway wall,
Bracing frame is shaped steel.
Further, curved cylinder under described siphon, the flow section that formed between curved cylinder dome and hoistway wall under siphon are equal
More than more than 9 times of vertical shaft flow section.
Further, it is provided with trash rack at curved cylinder horn mouth under described siphon.
Further, under described siphon, curved cylinder dome medial roof absolute altitude is identical with check flood level, curved cylinder loudspeaker under siphon
Mouth lower end absolute altitude is identical with flood control.
Suction Type Shaft spillway disclosed in this utility model, when running into big heavy showers, when in storehouse, water level reaches design
During flood level, Suction Type Shaft spillway not flood discharge, when in storehouse, water level reaches check flood level, Suction Type Shaft spillway
Under siphon vacuum condition of negative pressure, quickly reservoir level can be down to design flood to exceed nearly 9 times of flow velocity high speed flood discharge than overflow
Water level, ensures reservoir safety.Run into general rainfall, in storehouse water level reach design flood level and not up to check flood level when, rainbow
Suction shaft spillway not flood discharge, water level continues to rise, as long as water level does not reach check flood level, Suction Type Shaft spillway
All without flood discharge, terminate to rainfall, this part libraries water exceeding design flood level is saved, and improves effective profit of reservoir
With rate, reservoir safety can be ensured, take full advantage of design flood level again and hold water to the security vault between check flood level, can
Obtain very big economic benefit.
Brief description
Fig. 1 is Suction Type Shaft spillway schematic diagram；
Fig. 2 is a-a generalized section.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1=2, Suction Type Shaft spillway of the present utility model, by basis 1, hoistway wall 2, vertical shaft 3, flood discharge
Tunnel 4, flood-discharge tunnel wall 5, flood-discharge tunnel tail lock 6, curved cylinder 7 under siphon, curved cylinder horn mouth 8 under siphon, curved cylinder dome under siphon
9th, bracing frame 10 forms, under curved cylinder horn mouth 8 under curved cylinder 7 under described siphon, siphon, siphon curved cylinder dome 9 be fixedly installed for
One is overall, is made of stainless steel, described bracing frame 10 one end is fixedly installed with cylinder 7 curved under siphon, and the other end is solid with hoistway wall 2
Fixed setting, bracing frame 10 is shaped steel.
The flow section being formed between curved cylinder dome 9 and hoistway wall 2 under curved cylinder 7 under described siphon, siphon is all higher than erecting
More than 9 times of well 3 flow section, is provided with trash rack at curved cylinder horn mouth 8 under siphon, curved cylinder dome 9 medial roof absolute altitude under siphon
Identical with check flood level, under siphon, curved cylinder horn mouth 8 lower end absolute altitude is identical with flood control.
When Suction Type Shaft spillway of the present utility model uses, run into big heavy showers, when in storehouse, water level reaches design
During flood level, Suction Type Shaft spillway not flood discharge, when in storehouse, water level reaches check flood level, Suction Type Shaft spillway
Under siphon vacuum condition of negative pressure, quickly reservoir level can be down to design flood to exceed nearly 9 times of flow velocity high speed flood discharge than overflow
Water level, ensures reservoir safety.Because curved cylinder horn mouth lower end absolute altitude is identical with flood control under siphon, check flood when running into
During water, Suction Type Shaft spillway i.e. can high speed flood discharge to design flood level close flood-discharge tunnel tail lock, again can according under
Trip flood control needs to continue to sluice at a high speed to turn off flood-discharge tunnel tail lock to normal pool level or flood control.Run into general fall
Rain, when in storehouse, water level reaches design flood level, Suction Type Shaft spillway not flood discharge, water level continues to rise, if water level reaches
Less than check flood level, Suction Type Shaft spillway all without will not flood discharge, terminate to rainfall, exceed this portion of design flood level
Point storehouse water is saved, and improves the effective rate of utilization of reservoir, can ensure reservoir safety, takes full advantage of design flood again
The security vault to check flood level for the position holds water, can obtain very big economic benefit.
