Abstract

The utility model discloses a hydraulic linkage valve device for water collection wells of a ventilating shaft set. The hydraulic linkage valve device is installed on a pipe orifice of a drainage linkage pipe of the water collection wells of a subway tunnel. The hydraulic linkage valve device comprises a float bowl insertion board and an insertion board framework, wherein the float bowl insertion board is a square insertion board with a float bowl; the insertion board framework is a framework with a U-type insertion groove; the square insertion board is inserted into the U-type insertion groove of the insertion board framework and vertically moves inside the U-type insertion groove. The length of one side of the float bowl insertion board is equal to the diameter of the pipe orifice of the drainage linkage pipe, and the height of the insertion board framework is twice as much as the diameter of the pipe orifice of the drainage linkage pipe. When no rainwater flows into the water collection wells, the float bowl insertion board of the hydraulic linkage valve device falls on the bottom of the insertion board framework along the insertion groove under the action of gravity, and drainage pipe orifices of the water collection wells are blocked; when rainwater flows into the water collection wells, the float bowl insertion board of the hydraulic linkage valve device floats in the water, the drainage pipe orifices are exposed out, and accumulated water is gathered through drainage pipes to the water collection well provided with a lift pump to be drained out. The hydraulic linkage valve device not only can prevent the water collection wells from being tainted by other odor in the ventilation process, but also can lower expenses for engineering construction, operation and maintenance.

Description

Ventilating shaft group sump waterpower coupling cock device
Technical field
The utility model relates to subway tunnel equipment, particularly relates to subway tunnel sump equipment.
Background technique
At present, subway tunnel generally will arrange ventilating shaft, with ventilation, for passenger and staff provide the suitable environment of an activation.In underground station, the ventilating shaft concentrated setting of dispersion, composition ventilating shaft group.Ventilating shaft group is generally made up of 1 air draft well, 1 new ventilating shaft and 2 piston vents.Air draft well arranges air draft machinery, if desired gas in tunnel is extracted out discharged to atmosphere.New ventilating shaft arranges exhausting machinery, if desired by fresh air suction tunnel.Piston vent, mainly relies on the piston action by train in tunnel, and gas in tunnel is discharged or inhale fresh air.
Subway tunnel ventilating shaft group is generally outdoor form, and in order to get rid of rainwater and percolating water, each ventilating shaft arranges respectively rainwater sump and draining elevator pump equipment thereof.Each ventilating shaft arranges respectively 1 sump and 2 cover elevator pump equipment, and in the finite region of a ventilating shaft group, 4 sumps need be established 8 cover elevator pump equipment altogether, invest relatively large., sump is connected by draining cross over pipe for this reason, only in a bite sump, elevator pump is set, the water of 4 sumps of ventilating shaft group is concentrated and discharged.But draining cross over pipe connects sump, easily makes each ventilating shaft ventilation taint of odour, can not meet the ring control requirement of ventilation.
Model utility content
For existing subway tunnel ventilating shaft group sump, the draining of draining elevator pump equipment independence need to be set respectively, have the problem that investment is relatively large, management maintenance is numerous and diverse; And the central drainage of sump draining cross over pipe is set, can not meet again the ring control problem of each ventilating shaft ventilation.The utility model arranges waste pipe and at the mouth of pipe, waterpower coupling cock device is installed in sump, utilizes sump water level buoyancy, automatically closes or open waterpower coupling cock device, just can solve the problem of above existence.
The waterpower coupling cock device that the utility model relates to, being installed on sump draining cross over pipe discharges on the mouth of pipe, comprise floating drum plate, plate framework, floating drum plate is the square plate with floating drum, plate framework is the framework of band " U " type slot, and the square plate of floating drum plate inserts in " U " type slot of plugboard frame frame and moves up and down in slot.Plate framework peripheral band bolt hole, bolt is fixed on plate framework on the flange plate of the draining cross over pipe mouth of pipe.The length of side of floating drum plate equals draining cross over pipe mouth of pipe footpath, and the height of plate framework equals twice draining cross over pipe mouth of pipe footpath.When sump has the time of catchmenting, water buoyancy holds up floating drum plate, and sump draining is discharged by pipeline; When nothing is catchmented, floating drum plate falls and blocks the draining cross over pipe mouth of pipe under self-gravity action, thereby avoids each ventilating shaft by draining cross over pipe ventilation taint of odour.Only realize, in a sump, elevator pump has been set, just the draining of 4 sumps of ventilating shaft group can have been concentrated and discharged, and do not affected the ring control requirement of ventilation.
The waterpower coupling cock device that the utility model relates to, substantially non-maintaining, energy-conservation.Waterpower coupling cock device, has optimized the drainage system facility of ventilating shaft group: draining connecting tube is set between sump, in other sump waste pipe imports, this device is installed, only in 1 sump, elevator pump equipment being set can concentrate discharge.Drainage system after optimization, both met the ring control requirement of not taint of odour of ventilation, can hydraulic automatic machinery part substitute electric power elevator pump equipment again, reduce the specification that arranges of other sumps, the former requirement condition that two elevator pumps are set, be the condition that arranges of a valving now, the utility model reduces engineering construction and operation maintenance expense.

Embodiment
By reference to the accompanying drawings the technical solution of the utility model is further illustrated, Fig. 1 and Fig. 2 have shown the basic structure of ventilating shaft group sump waterpower coupling cock device and situation have been set.As shown in the figure, the waterpower coupling cock device that the utility model relates to, being installed on sump draining cross over pipe discharges on the mouth of pipe, comprise floating drum plate, plate framework, floating drum plate is the square plate with floating drum, and plate framework is the framework of band " U " type slot, and the dual-side of framework and base are with " U " type slot, the opening of " U " type slot is towards the center of framework, and the square plate of floating drum plate inserts in " U " type slot of plugboard frame frame and moves up and down in slot.Plate framework peripheral band bolt hole, bolt is fixed on plate framework on the flange plate of the draining cross over pipe mouth of pipe.The length of side of floating drum plate equals draining cross over pipe mouth of pipe footpath, and the height of plate framework equals twice draining cross over pipe mouth of pipe footpath.When sump has the time of catchmenting, water buoyancy holds up floating drum plate, and sump draining is discharged by pipeline; When catchmenting, floating drum plate falls and blocks the draining cross over pipe mouth of pipe under self-gravity action.
