Description

The invention relates to hydraulic engineering and can be used to block the openings of large spans, mainly in ice conditions with fluctuations in the level of the upstream, with large wind and wave loads.

The purpose of the invention is to simplify the design, increase reliability, stability and simplify maneuvering.

FIG. 1 shows a diagram of closing the shutter in the presence of an ice field, front view; in fig. 2 is a diagram of the opening of the shutter, front view; in fig. 3 — shutter, front view, at the intermediate position of the span; in fig. 4 shows section A-A in FIG. 3, when closing the shutter; in fig. 5 is the same section BB in FIG. 3; in FIG. 6 6 - section A-A in FIG. 3, when the shutter is opened; in fig. 7 is the same, section BB in FIG. 3; in fig. 8 shutter, in axonometry; in fig. 9 is a section bb of FIG. 2; in fig. 10 shows a section of YYY in FIG. 2

The shutter includes a span structure consisting of two sections 1 and 2, equipped with hermetic weighing compartments 3, located in their lower part, and ballast compartments 4 in the upper part. Each section 1 and 2 of the superstructure is equipped with vertical support units with wheels 5 and mounted on track 6 with the possibility of oncoming movement to the middle of span 7. Each section

1 and 2 of the superstructure are provided with horizontal support-traveling parts | 8 parts, mating with additional inclined paths 9 for them. Sections 1 and 2 of the span are made of a wedge-shaped form in the plane of the span 7 and face large side edges 10 towards each other. The tracks b are made with a slope to the middle of the span 7. The horizontal support chassis 8 are made in the form of wheels mounted on the vertical uprights 11 of the support wheels 5. The base plate 12 is equipped with a set of cantilever ledges 13 along the tracks 6, on which the tracks 6 are fastened parallel to the tracks 6 support beams 14.

The beams 14 are made with additional paths 9 and 15 on the lateral edges and lower fans for support-running parts 8 and wheels 5.

The inclined paths 6 of the support wheels 5 are made on the slab 12 of the base of the span 7 and continue beyond the span of 7 on the slab 16 of the bottom of the dock chambers 17, designed to repair and inspect sections 1 and

2 span structure. In thicker slabs 12 and

16 can accommodate transport and operational tunnels.

The bottom edges 10 of sections 1 and 2 of the superstructure on the side of the overlapped

the holes are made in the form of a wedge ice-breaking edge 18 (Fig. 8) in height within the limits of possible contact with an ice field or cables.

The projections 13 and the beams 14 are located from

the middle part of span 7 at a length equal to

h

In tga

where B is the width of the span of 7, m; h - the height of the protrusion 13, m; and - the angle of inclination of the paths to the horizon. Shields 19 are attached to the doors 1 and 2 on the upper side.

If necessary, quickly block span 7 in difficult ice conditions, both sections 1 and 2 of the superstructure, which were so far outside span 7 in the dock chambers 17, begin their movement along an inclined path 6 towards each other. For this purpose, the hermetic weighing compartments 3 are filled with water or, when compartments 3 are pre-filled, they relieve the braking force from sections 1 and 2. To overcome the powerful ice accumulations

force generated by weight

sections 1 and 2, directed along the paths,

can be increased by filling the compartments 4.

With a possible wave oscillation and

a surge in the water level in the upper .biefe within the span 7 of the overlapping aperture creates powerful currents of water, turbulent swirling of the flow throughout the water column. However, section 1 and

2, loaded with their own weight, are in a stable position on the track x 6. with which the support wheels 5 interact. And with the horizontal displacements prevent the path 9, with which the horizontal support-chassis 8 interact. When the shutter gate is closed, the water surge rises in span 7, from the upstream side, it is perceived by the upholstery 3aTBop k and transmitted through the gate construction further through the pillars 11, through the horizontal supporting chassis 8 on the track 9, and the tilting moment through the supporting wheels 5 to the top Chow Ways 15 and Grassroots Ways 6.

If it is necessary to open the shutter, the compartments 3 are emptied of water and they create a weighing force acting on the shutter sections 1 and 2, exceeding their weight. There is a slight magnitude

the ascent of sections 1 and 2 of the superstructure

up to the bearing of the wheels 5 on the additional tracks 15. The horizontal support parts 8 at the same time remain in cooperation with the tracks 9, which are made with the appropriate width.

Sections 1 and 2 of the gate span rise along inclined tracks 15, resting on the wheels 5. beyond the span of the opening 7 to the dock chambers 17, being in a stable position, taking into account that when opening the horizontal loads are reduced to a minimum.
