Description
Technical field
A kind of buoyancy aid door that the utility model relates to, relates in particular to a kind of screw and drives buoyancy aid door.
Background technology
Suzhou River is Huangpu River tributary, is the tidal river of a moderate strength, is often subject to typhoon.Suzhou River river mouth is affected by Huangpu River and Suzhou River bimodal current, streamflow regime complexity.2005, in Suzhou River river mouth, outer white transfer bridge downstream built up can " two-way water blocking; open and close flexibly " new sluice (be lower horizontal steel lock), substitute Wusong switch bridge defence Suzhou River area and suffer the function of off-lying sea morning and evening tides invasion and attack, and be that the water environment of improving this area has played key effect.But, because newly-built Suzhou River river mouth sluice is positioned at Suzhou River and enters the river mouth of Huangpu River, this place is sitting at Huangpu River bend, shipping is busy, and the operation condition of adding Suzhou River river mouth sluice is special, and underway ship be can't see gate sometimes, block ship's rigging and warning mark although be provided with before lock, but once ship's navigation is out of control or navigation in mishandling, still likely bump against newly-built Suzhou River river mouth sluice, so that badly influence safe, moistureproof, water supply and the navigation etc. of this area.
Consider importance and the particularity of engineering, the armamentarium of Suzhou River river mouth lock is arranged in the water surface or below ground (3.5m is following), and original view, style and features are not had a negative impact.River mouth lock span is large, close to river mouth, underwater portion, by maintenance-free design in 30 years, is not established access door, therefore once accident, not only maintenance difficulty is large and maintenance lasts long (3 months at least, 1 year semi-load at most).Consider that sluice is positioned at the bustling location in Shanghai, gate when maintenance river can not stop, stop navigation, and can not build cutout cofferdam, meets with wind, sudden and violent, tide three is met and discussed if happen astronomical spring tide, Suzhou River has just lost important defensive barrier, is badly in need of building the transition of emergency power tide-block sluice.Gear Chaoan in order to ensure Shanghai Central Urban Area, Suzhou River two sides is complete, prevents the adverse consequences that accident causes and reduces people's life and property loss.
The main task of Suzhou River river mouth emergency power tide-block sluice engineering is emergent gear tide,, in the time suffering off-lying sea storm tide invasion and attack, once there is accident or fault and can not normally bring into play its defensive barrier effect in newly-built Suzhou River river mouth sluice, can enable Suzhou River river mouth emergency power tide-block sluice, promptly forms second defence line, resist and within 200 years one, meet high water mark, play the effect of the damp mitigation of gear, ensure the safety of this area, but do not bear water resource scheduler task.
In addition, because engineering is located in the Main Scenic Spots, source, outbeach being formed by mansion, Shanghai, park, outbeach, Wai Bai transfer bridge UNICOM, the park, source, outbeach being connected with source, outbeach public green space will be formed along riverfront, Suzhou light greenly, therefore Suzhou River river mouth emergency power tide-block sluice engineering need with near scenic spot harmony, incorporation engineering carries out supporting landscape design.

Detailed description of the invention
For technological means, technical characterictic, utility model object and technique effect that the utility model is realized are easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in figure 1: a kind of screw drives buoyancy aid door 100, comprise ballasting 101 and with the described ballasting 101 cabin body 102 being integrated that joins, be provided with first post 1021 and stern post 1022 at the two ends of described cabin body 102, in described cabin body 102, be provided with fixing water tank 103.Above this fixing water tank 103, be provided with pump equipment cabin 104, at the symmetrically arranged deck layer 105 in the two ends in this pump equipment cabin 104, be provided with hydraulic power unit 107 at the deck layer 105 on first post 1021 and the left side.The height of cabin body 102 is less than or equal to the height of first post 1021 and stern post 1022.
The utility model middle deck layer 105 is symmetricly set in cabin body 102 with the vertical center line of cabin body 102, and this deck layer 105 comprises the upper deck 1051, middle deck 1052 and the lower decks 1053 that set gradually from top to bottom.
Hinged-support for joining with gate pier door pillar is installed on the vertical plane of first post 1021 in the utility model.The utility model comprises two screws, and the screw using in the utility model is groove-type screw, comprises that 202, one, the first screw 201 and the second screw use another as for subsequent use.A screw in use also can be installed separately.
Offer two is vertically arranged in through-flow mouthful 300 through through-flow mouth 300, the first screws 201 and second screw 202 of cabin body 102 in one end of cabin body 102.Two-port at through-flow mouthful 300 is provided with trashrack 302, and in anti-sealing, foreign material damage screw, normally use and affect it.At cabin body 102 through-flow mouthful of 300 places of a side near a river, be provided with flap valve (not shown), be used for preventing the trend leakage after buoyancy aid door is closed.
In the utility model, the axle center distance of the first screw 201 and the second screw 202 is greater than the diameter of twice screw; The slurry axle center of the first screw 201 and the second screw 202 to the distance of ballasting soffit is greater than one times of airscrew diameter.
With reference to figure 2,3, also comprise an overhead door 400, this overhead door 400 is installed along the length direction of cabin body 102, be provided with pull bar 401 in the inner side of overhead door 400, if the insufficient height of cabin body 102 in use, can boost overhead door by pull bar, to increase the height of whole cabin body 102.
Be the schematic diagram of the utility model in concrete use procedure with reference to figure 4:
(1) the groove-type screw that the utility model uses is positive and negative transition.In the time that buoyancy aid Men Gangcong warehouse compartment starts, screw is just transferring thrust makes buoyancy aid door shift out warehouse compartment, produce the impact to gate pier 500 along with the effect buoyancy aid door of current closes to close automatically, now screw starts reversion and sends pulling force, finally with the less impact buoyancy aid door 100 that closes.
(2) two screw equipment of the utility model buoyancy aid door assembling, the using and the reserved; The axle center distance of two screws is not less than twice airscrew diameter, to reduce by two interference between screw; The depth of immersion (oar axle center is to water surface distance) of screw is not less than one times of airscrew diameter and prevents the screw air-breathing negative consequence of bringing of when work;
(3) buoyancy aid door rotation angle degree.Rotate to 0 °～10 ° positions at buoyancy aid door, screw low speed forward, while rotating to 10 ° of left and right, screw quits work, during to 20 °, screw reversion slows down closing velocity, continuation with the anglec of rotation increases, and screw pulling force also constantly increases, and reaches maximum value at buoyancy aid door turn-off transient pulling force.
Be only the utility model preferred embodiment in sum, be not used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should belong to technology category of the present utility model.
