Background technology
Power station steel-slag sand gate slot is installed and is all as dam civil engineering progress and carries out, and bottom diversion outlet lock chamber or flood scouring lock chamber often dam because of cofferdam or pass the flood period needs flood season and carried out water in advance.Owing to the water of flowing containing substantial amounts of silt and foreign material, in the most mounted gate recess, easily form alluvial and block, cause have a strong impact on to closing smoothly steel-slag sand under follow-up dynamic water or hydrostatic state, make steel-slag sand to close and put in place, cause and leak or steel-slag sand is stuck.Accordingly, it would be desirable to first the silt in slag every groove and foreign material are cleared up.But, there is presently no special equipment and can apply to this workplace.
Summary of the invention
The goal of the invention of the present invention is: for the workplace of above-mentioned existence, it is provided that a kind of the most manned exploration door being exclusively used in cleaning power station steel-slag sand gate slot, for all kinds of large, medium and small Hydraulic and Hydro-Power Engineerings.Dirver utilizes the present invention front lower under water in steel-slag sand closure, operation track, bottom side sill and the top side sealing seat of steel-slag sand is carried out desilting, mud and other foreign material and clears up.
The technical solution used in the present invention is such that
A kind of the most manned exploration door being exclusively used in cleaning power station steel-slag sand gate slot, including box main body, trailing flank on length direction is upstream face plate, leading flank is downstream panel, described downstream panel is provided with mandoor, side bearing, main supporting and some concora crush inlet openings, described box body top is provided with lifting hanger and is communicated to the logical spool of inside, on the side column at described box main body two ends, concora crush inlet opening is set, described upstream face plate inwall in the vertical direction arranges some longerons, it is horizontally disposed with U-shaped girder between adjacent two longerons, described U-shaped kingpost baseplate is fixedly connected on upstream face plate inwall, the described box body interior half side service aisle that through left and right is set downstream, offer some holes bottom service aisle and safe fence is set near hole.
Concora crush hole is to ensure that exploration door, when entering high-velocity flow, makes exploration door water flow inside tend to backwater state slowly, it is ensured that underwater operation personnel do not impacted by current, makes exploration door inside and outside consistent by water pressure, it is ensured that to sound out door and run safety simultaneously.
Offer hole bottom service aisle, staff can be made in box body interior, the foreign material in steel-slag sand gate slot to be cleared up.Safe fence is set near hole, can fall in hole with staff's imprudence under prevention of water and have an accident.
Logical spool facilitates the oxygen supplying tube of staff and the cable of underwater camera to pass through.
The setting of lifting hanger, facilitates the present invention to be connected realization lifting with hoisting machinery.
Owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, manufacture, easy for installation；
2, may be used in all kinds of large, medium and small Hydraulic and Hydro-Power Engineering, steel-slag sand gate slot, after flood is interrogated the phase and crossed water and after upstream cofferdam demolition blasting, utilizes the present invention can effectively solve steel casement door groove and carries out underwater camera inspection, cleaning and strobe track total travel by the key technical problem checked；
3, the present invention is safe and reliable, enters water and goes out water steadying, shake little under the conditions of the most dynamically current, diver feels good, the most very convenient to the cleaning of steel casement door groove and inspection under water, it is ensured that steel-slag sand descends water smoothly and once closes a success, and its sealing property meets industry acceptance specification requirement.
As preferably, it is arranged on the downstream panel left end of box main body including mandoor.
As preferably, described main supporting and collateral support are distributed in panel left and right, downstream end.Main supporting and side be supported on when the present invention enters steel-slag sand gate slot play spacing, buffer and transmit the effect of flowing pressure, meanwhile, gate is run track gauge little progress row by checking.
As preferably, described concora crush air inlet is distributed in the left end of downstream upper panel, middle part, right-hand member.Concora crush air inlet is arranged on the side column at downstream upper panel and box main body two ends, the present invention can be made slowly to enter water logging when being less than top, water enters into box body interior by the hole of each concora crush inlet opening at downstream panel and side column and bottom, in making box main body, external water pressure is equal, concurrently form backwater zone slowly, diver can be made in the walking under water of geo-stationary and work.
As preferably, the biside plate end of described U-shaped girder is respectively provided with the baffle plate vertical with side plate and forms T-shaped structure.The structure of upstream can be reinforced by U-shaped girder, and T-shaped structure makes the end safety of U-shaped girder higher, both ensure that the intensity and toughness souning out door, and in turn ensure that diver's trouble free service in the confined space.
