Abstract
The utility model discloses a tower water inlet structure of power station bank, including the tower body, be located the top of the tower platform that has a bracket of encorbelmenting in succession of tower body upper end, it has at least one fall L shape air vent to open in the tower body, vent is located the tower body side, it has into manhole to link up perpendicularly downwards to open on the bracket of encorbelmenting of top of the tower platform, should advance the manhole and be located air vent one side, advances the manhole export near vent, vent and advance manhole export under be equipped with the maintenance of encorbelmenting and advance people's platform, this examines and repair into that people's platform becomes the walking passageway of connecting vent and advancing the manhole export. The utility model discloses the influence of air vent air current to top of the tower platform building, traffic and staff has not only been eliminated to greatly reduced the tunnel maintainer degree of difficulty that gets into the air vent. On guaranteeing to ventilate and examine and repair two major basic function's of people into basis, the safety reliability of air vent operation has greatly been improved.
Description
Technical field
The utility model relates to a kind of power station bank tower intake structure.Be applicable to the bank tower intake that continuous bracket established by power station or water-control project inlet gate tower top platform.
Background technology
Bank tower intake due to comparatively wide to landform geological conditions compliance, and is widely used.Air vent after its gate 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, bank tower intake structure tower top 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, and tower top size is usually less, limited space.Air vent after bank tower intake gate arranges the mode usually adopting straight-through tower top, or adopts in the distance tower top certain distance mode that turns out of level from the side.
When air vent adopts the arrangement of straight-through tower top, be usually provided with the cover plate of band grid at tower top air vent place.The high velocity air produced when air vent tonifying Qi and exhaust, certainly will produce considerable influence to the personal safety of tower top 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, water inlet tower top 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 is arranged in outside closed framed bent, because vent size is comparatively large, and tower body self structure size is less, arranges and is often difficult to by space constraint realize.
When air vent adopts when arranging apart from the tower top certain distance mode that level turns out from the side, though the high velocity air that produces is on the impact of tower top traffic and field personnel when effectively can avoid air vent tonifying Qi and exhaust, 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.Because tower top platform is with bracket of encorbelmenting continuously, is suspended in aerial time under maintainer's lifting rope near air vent, cannot air vent be entered, certain potential safety hazard is existed to maintainer's personal safety.
From the current analysis to prior art, existing power station bank tower intake structure can not meet ventilation safety simultaneously and maintenance facilitates this two technical requirementss.
Utility model content
For the problems referred to above, the utility model aims to provide one and can ensure ventilation safety simultaneously and overhaul power station bank tower intake structure easily.
The technical scheme that the utility model is dealt with problems is: a kind of power station bank tower intake structure, comprise tower body, be positioned at the tower top platform with bracket of encorbelmenting continuously of tower body upper end, at least one inverted L-shaped air vent is had in tower body, air vent outlet is positioned at tower body side, throughly vertically downward on the bracket of encorbelmenting of tower top platform have enter hole, this enter hole is positioned at air vent side, and enter hole exports near air vent outlet;
Be provided with the maintenance of encorbelmenting immediately below described air vent outlet and enter hole export and enter people's platform, this overhauls becomes into people's platform the walking passageway connecting air vent outlet and enter hole's outlet.
In technique scheme, enter hole and air vent not at grade, but are staggeredly arranged, and the exhaust of air vent and tonifying Qi are all carried out from tower body side, away from tower top platform, can not affect tower top building, traffic and staff.During maintenance, staff enters from enter hole, entering air vent and overhauls, conveniently can enter air vent through overhauling into people's platform.
Further, the enter hole import department of tower top platform be provided with can by complete for enter hole's import totally enclosed movable sealing cover plate.This cover plate was opened in turn(a)round, arrives overhaul into people's platform for maintainer, and non-turn(a)round closes, and guarantees tower top traffic safety.Because enter hole and air vent adopt plane to be staggeredly arranged mode, therefore do not have stream pressure in enter hole, this deck design is simple and easy, the well lid on similar common road, as long as quality meets traffic and relevant load requirement.And traditional air vent double maintenance enter hole aperture cover plate needed to open in turn(a)round, want secure lock in non-turn(a)round, complex structure, performance requirement is higher.
For convenience of maintainer's walking, described enter hole is exported to the tower body sidewall overhauled between people's platform and is provided with cat ladder.
Preferably, described maintenance is provided with protective guard into people's platform, ensures maintainer's personal safety.
Remarkable result of the present utility model is:
1. air vent and enter hole are staggeredly arranged, and enter hole is imported and exported and is separated with air vent Way out, eliminate air vent air-flow for the impact of tower top platform and vibrations harm, eliminate the impact of air-flow for tower top platform vehicle and staff.
2. overhaul and connect air vent and enter hole into people's platform, greatly reduce the difficulty that tunnel for overhaul personnel enter air vent.
Ensureing ventilation and overhauling on the basis of the large basic function of people two, drastically increase the safety reliability that air vent runs.
