Description

This invention relates to the further development of floating gate valves for dry-dock gates, made in the shape of rectangular w; having waterproof compartments and moving, afloat in the niche of the gate. To this end, the invention provides for the creation of a primary seal the supply of the gates of the docks with hydraulic jacks that can be moved by means of a winch in vertical directions on the walls of the gate niche. The jacks are located on the foundations of the gate near the supports for the gate and serve to bring it to the embedded parts.

In FIG. 1 shows a schematic longitudinal section (along the AB in FIG. 2) along the axis of the niche and the shutter in its working position; FIG. 2 - top view of the shutter (with a cut along the ballast and; ikam); FIG. 3 is a cross section (according to CD in FIG. 2); FIG. 4 and 5 - installation of hydraulic jacks in two projections.

The proposed floating sliding slide is a metal rectangular chic fitted with plating (both on the sea and on the dock side) with waterproof compartments that allow the shutter to keep afloat when diverted to niche 1 or to be immersed at the threshold of the dock gate when it is filled with water. .

In the drawing, the chic is divided by four decks into three parts in height (FIG. 1) and three transverse bulkheads into four parts in length (FIG. 2). The space between the middle decks, along the entire length of the gate, is used to arrange twelve compartments 2, which are formed by setting within, the middle decks of one longitudinal bulkhead and five transverse ones. In addition, the entire space bounded by the upper deck and the middle deck that follows it and with single transverse bulkheads is also used to place four ballast chines 3, which mainly serve to create a smooth fit for the slide when it is immersed. All deck bulkheads and exterior plating to create strength and stability of structures, supported by the corresponding frame frames, stiffeners and pilers.

For a more even distribution of the load between the upper and second decks, a waterproof half-board 4 is arranged, capable of supporting the hydrostatic pressure of water that comes to it. In the two extreme diagonally arranged waterproof buoyancy boxes (compartments) 5, duplicated electron-axial installations are installed to pump the boxes. The regulation of the pumping out of each of the boxes, as well as their filling, is carried out with the help of clinkers 6, placed in each compartment on a special ballast and filling pipeline laid in all of the boxes of buoyancy. The management of the blades was made by the iBepxHroro deck. The pumps are powered using a flexible hose from a plug column on the head to: ka .. When the gate is opened (the entrance to the dock). The lock is retracted to "ish 1, fuse: hitting it from damage by vessels when entering the dock and the wind and waves, as well as creating a reliable sp-rvlenie when moving the shutter. The saTieopa relocation is carried out with the help of the electrochips mounted on the dock's head. Moving the lock in the transverse direction, and mainly keeping it in a certain position and adjusting this position is carried out using the tie-rods on the walls of the dock and canifas blocks 7 (Fig. 2). For the landing of the bolt on the bottom, on the end of its walls there are onorner shoes. Accordingly, at the threshold of the dock laid in the body of concrete o (nof№, on which the shutter sits. The shutter can be placed on supports when it is in any position, including in a twisted position, or in a position where the sealing bars are. Far away , from such parts that the pumps of the central doyouya station during pumping can not create the difference between the horizons of water in the dock chamber and the bay required for pressing the shutter. To determine the position of the lock and initial pressure of the dock, two hydraulic hoses are installed Typical construction (Fig. 4 and; 5). Households are located on the head of the dock in the area of the rotor support. To maintain the operation, the jacks are lifting and are stored on the head of the dock in a raised position from the water, which makes it possible to inspect them before starting work. Lifting the jacks out of the water and lowering them to the gate supports is carried out by the docking spiers closest to the jack by means of cables 8 slung over blocks 9 mounted on metal racks (Fig. 4 and 5). The jacks are powered from the pump 10 through two flexible hoses 11, supplying fluid in the cavity of the forward and reverse strokes of the jack plunger. When jacks are lifted, the Depuyuk equipment hoses on the drums 12, automatically set in motion, simultaneously with the jack lifting, loads 13. The installation of the jack under water is ensured by vertical guides 14, embedded in the concrete of the dock, in which the tail part of the jack is moved. In order to exploit valves in the winter, heating of steam gates of the valves themselves and their Niš may be provided. Steam may be supplied by flexible hoses from the factory network. To reduce heat losses, the valves from the sides and on the upper Deck are sheathed with wooden flooring, and the gate niche itself is covered with a light wooden floor.
