Description
Technical field
The utility model relates to a kind of gate of hydropower station shaft intake structure.
Background technology
The air vent of hydro water inlet except the function be vented when tonifying Qi and water-filling when meeting tunnel drainage, when tunnel after gate have maintenance to require and without other available access paths time, also should have the function of tunnel for overhaul passage.Air vent cross dimensions should meet the ventilation requirement current with maintenance, and has corresponding safety prevention measure.
In prior art, the operating platform of gate shaft formula water inlet structure is generally furnished with hydraulic structure and the relevant opening and closing devices such as headstock gear bent columns (containing headstock gear), gate slot, access bridge, air vent.Because whole gate shaft structure is arranged in massif, air vent generally can only take the arrangement of direct mode operation table top.Service work personnel in power station pass in and out air vent and tunnel by the cat ladder climbing be arranged in air vent.When air vent adopts the arrangement of direct mode operation table top, be usually provided with the cover plate of band grid in air vent exit.The high velocity air produced when air vent tonifying Qi and exhaust, certainly will produce considerable influence to the personal safety of operating platform traffic and field personnel, there is certain potential safety hazard.
Particularly for the intake of hydropower station of boreal climate severe cold area, for preventing gate slot from freezing, affect the normal keying of gate, headstock gear framed bent is made closed usually, the outlet of air vent is also enclosed in a confined space.Though closed bent structure is conducive to gate slot warming, cannot meet the normal tonifying Qi of air vent and exhaust requirements, the strenuous vibration of bent structure and the badly damaged of door and window are usually caused in airtight space; Otherwise to meet air vent tonifying Qi and exhaust requirements, closed bent structure door and window certainly will will adopt blinds or paling form, and this cannot meet again the warming requirement of gate slot.If air vent turns round in distance operating platform a distance, obliquely to stretch out, make it export to be arranged in the outside of closed framed bent, and exceed operating platform certain altitude.Though the high velocity air that produces is on the impact of operating platform traffic and field personnel when this arrangement can avoid air vent tonifying Qi and exhaust effectively, but for requiring to double as the air vent of tunnel for overhaul enter hole, this arrangement pole is unfavorable for that maintainer goes into the well maintenance, exists certain potential safety hazard to maintainer's personal safety.
In addition, hold concurrently for water inlet air vent and overhaul enter hole, method the most frequently used in engineering is that anchor bar (or other materials), as cat ladder, is climbed up and down for maintainer on hole wall.Large hydropower station water inlet air vent usual tens meters even darker, maintainer climbs up and down wastes time and energy, and greatly reduces service work efficiency; In addition be anchored at the cat ladder of hole wall or handrail owing to getting rusty, the reason such as corrosion exist come off enter tunnel may, affect the safe operation in power station.
From the current analysis to prior art, existing gate of hydropower station shaft intake structure can not meet ventilation safety and overhaul efficiency these two technical requirementss high simultaneously.
Utility model content
For the problems referred to above, the utility model aims to provide and a kind ofly can ensure ventilate safety and the high gate of hydropower station shaft intake structure of overhaul efficiency simultaneously.
The technical scheme that the utility model is dealt with problems is: a kind of gate of hydropower station shaft intake structure, comprise gate shaft, be positioned at the operating platform of gate shaft upper end, air vent is had below operating platform, in gate shaft, on air vent top, Proximity operation table top position bifurcated has bifurcated pipe, bifurcated pipe is communicated with air vent, and bifurcated pipe extends to operating platform top, this bifurcated pipe is as the exit passageway of air vent; Air vent upper end extends the enter hole being provided with direct mode operation table top straight up;
Described bifurcated pipe exit is provided with airflow guiding device;
Described bifurcated pipe outlet is arranged at outside headstock gear framed bent;
Enter hole import department is provided with can by complete for enter hole's import totally enclosed seal cover board.
In technique scheme, the air vent outlet non-traffic be arranged on outside framed bent requires side, eliminates air vent exit flow for the impact of closed framed bent and vibrations harm.Seal cover board is only opened for tunnel for overhaul in the tunnel for overhaul phase, and non-turn(a)round cover plate closedown also secure lock, to resist surge during air vent exhaust.
Described airflow guiding device be build by laying bricks or stones in bifurcated pipe exit export the identical pipeline of bore with bifurcated pipe, this pipeline is arranged perpendicular to operating platform.Because pipeline exceeds the certain safe altitude of operating platform, eliminate the impact of air vent air-flow for operating platform building, traffic and staff.
Further, cat ladder is not established in described air vent and enter hole.Adopt hanging basket or interim gin pole etc. to open the mode of hanging vertically to transport maintainer and arrive at tunnel inside, efficiency is high, eliminate because of cat ladder because of getting rusty, the reason such as corrosion comes off and enters tunnel, the potential safety hazard of threat power plant safety.
Preferably, the pre-buried anchor ring of described enter hole aperture surrounding.When fixing the interim lifting appliances such as gin pole for turn(a)round.
Remarkable result of the present utility model is:
1. air vent and enter hole are staggeredly arranged, and air vent outlet are arranged in outside headstock gear framed bent, eliminate air vent air-flow for the impact of closed framed bent and vibrations harm.Meanwhile, the setting of airflow guiding device also eliminates the impact of air-flow for operating platform traffic and staff.
2. air vent is vertically communicated with enter hole, and the cat ladder or handrail climbed for maintainer are not established in inside, vertically can transport maintainer and arrive at tunnel inside.Greatly reduce the difficulty that tunnel for overhaul personnel enter air vent, improve service work efficiency; And eliminate cat ladder because getting rusty, the reason such as corrosion enters tunnel after coming off, and threatens the unfavorable factor of power plant safety.
