Description

The invention relates to the field of hydraulic engineering.

Known sliding gates, consisting of a water-retaining structure based on a flutbet with support-running parts. However, these gates have a complex span structure, since the overturning moment from the hydrostatic load is balanced by the own weight of the structure and the weight of the ballast.

Consider a retractable shutter according to A.S. No. 387079. The purpose of this invention is to ensure the operation of the shutter with a two-sided pressure. Its water-retaining superstructure is made with support-running parts mounted on guides located in the flutebet groove. With a double-sided pressure, the water-retaining superstructure is made with additional support-running parts mounted on guides located in the groove of the flute, to which the shields overlapping the groove are pivotally attached.

The disadvantage of the considered shutter - analogue is the bulkiness of the structure, unreasonably inflated dimensions, high consumption of building materials and metal. Increased cost and certain difficulties in operation.

As a prototype, we take A.S. No. 949056 - Sliding gate, which consists of a water-retaining superstructure, made in the form of a shield, mounted on rails and in the presence of seals. The shutter has a traction cable and movement mechanisms. Moreover, the span structure (shield) is divided into sections. When opening and closing the lock, the shutter-shield moves along the axis of the gate along the flutber and the rail.

The disadvantage of the considered gate - the prototype is the bulkiness of the design, unreasonably inflated dimensions, high consumption of building materials and metal. Unilateral water restriction and appropriate waterproofing. Increased cost and certain difficulties in operation.

The purpose of the invention. Shutting off the two-way water pressure, increasing energy efficiency and reliability during operation, reducing the size and consumption of structural materials, reducing capital investments when creating the design of the proposed sliding gate (OS) for blocking hydraulic structures according to Fig. one.

The O3 shield consists of several plates-1, 2-wheels, 3-loops, 4-rails that guide and hold the wheels, a 5-base lower shutter beam rigidly fixed to the bottom of the flutber-7, and the most lower plate of the OZ, 6-pit for folded gate plates, 7-flutber design, 8-movement mechanism of the OZ, 9-drum for the cable, 10-cable, 11-base upper beam, to which the cables and the upper plate of the OZ are attached, 13- butt seals, 14-inclined flutber railings, 15-fastening of cables 10 to the beam-11. The developed sliding gate (OZ) in the form of a shield, divided into sections and mounted on guide rails-4 in the presence of seals 13-20, has a traction cable-10 and movement mechanisms-8 on wheels-2 along rails-4 located on a flutber- 7. Plates-1 are used as sections of the shield (a composite structure is assumed to provide rigidity from transverse bending), interconnected by hinges-3, and for waterproofing, butt-13 and side-20 seals are installed on the plates. The lower plate of the shield is hinged to the base lower beam-5, rigidly fixed at the bottom of the flutber-7, and the upper plate of the shield is attached through hinges-3 to the base upper beam-11, which is connected to the corresponding mechanism through the fastening of cables-15 and cables-10 movement-8 through the drum-9 for the cable, Resistance to water pressure is created by stretched cables, They carry out the tension of the shield plates, and to move the shield plates parallel to the inclined railings-14 of the flutber-7 and hold them on the guide rails-4, wheels-2 are provided, hinged to odd plates. Shield waterproofing in the mode - U-turn and bilateral water retention - is provided by butt 13 and side-20 seals fixed on plates-1.

The movement mechanism-8 according to Fig. 2 includes a 16-electric drive, a 17-unit for synchronizing electric drives with speed and position sensors of these electric drives, which provides protection for the shield plates from distortions, jamming in the 2nd and 3rd operating modes of the OZ, 18-couplings, 19-reduction gear, shafts-12. OZ has 3 modes of operation:

1. Folding condition. The structure of the OZ shield is in pit-6 in a folded state without water or under water. At the same time, with the help of cable-10, communication is carried out with electric drives-16 from the movement mechanism-8 through drums-9 and fastening of cables-15 to the base upper beam-11.

2. Turning and bilateral retention of water by a shield OZ - an inclined plane at an angle-L. Electric drives-16 are switched on from the movement mechanism-8 and in the mode of coordinated rotation by the synchronization unit-17 provide a step-by-step (for each regular plate) lifting of the shield from the pit-6 and further lifting with the help of two cables-10 fixed on the base upper beam-11 along Fig. 3. At the end of this mode, a full turn of the plates-1 of the shield of the OZ is carried out and, reinforced by electric drives-16 from the movement mechanism-8 with cables-10, the tension of the shield structure, which resists the pressure of water under it. Waterproofing is carried out by seals 13, 20. If, after turning the shield OZ, water is above it, the edges of the plates-1 are pressed by side seals-20 according to Fig. 5 to the inclined railing-17 flutber-7. In addition, when the shield structure is tensioned, butt seals-13 on plates-1 according to Fig. 4 provide waterproofing relative to the space under its structure in the absence of water there. Thus, the proposed OZ provides a two-way overlap of water.

3. Folding of the OZ shield plates. This mode can be carried out in water and in its absence. When the tension of the cables-10 is weakened under the own weight of the upper beam-11 and plates-1, the shield OZ is folded with the help of loops-3, the plates are alternately shifted down the inclined railings-14 of the flutber-7 at an angle-L, for example, 75 degrees, and electric drives-16 operate in generator mode, setting the limited speed of lowering plates-1 on wheels-2 along rails-4 installed in the design of the flybet-7 next to its railing-14. The design of the rails-4, guiding and holding wheels-2, fixed on the odd plates-1 with the help of loops-3 according to Fig. 6 prevents bulging of individual plates and their chaotic lowering down in the mode - Folding - to the pit-6 and keeping these wheels engaged with the rails until the end of this mode. Uniform synchronous operation of both electric drives in this mode is provided by the synchronization unit of electric drives-17. At the end of this mode, the plates-1 of the shield of the OZ are pressed against each other and fit into the pit-6.

The principle of operation of the lock is as follows: after filling the chamber with water, the entrance gate-shield of the OZ is first opened (mode - Folding plates), and the vessel enters the chamber and moors to the bollards. The OZ Entry Gate is then closed (Turn Mode) and the bypass valve is opened, causing the water level in the chamber containing the ship to fall or rise. This is achieved by overflowing or pumping water from an adjacent reservoir in the direction of the vessel. When the water reaches the required level, equal to that which is available behind the exit gate-shield of the OZ chamber, the latter are opened (mode - Folding plates of the second OZ shield), and the vessel leaves the lock. During the operation of the gateway, all 3 main modes of operation of the OZ are used. The developed OZ can be widely used in shipping channels, especially when using new durable materials for seals and plates.
