Description

The invention relates to hydraulic structures.

The purpose of the invention is to increase ship passes, reduce the cost of construction, increase power generation - energy saving.

Fig. I shows the proposed gateway, a general view; Figure 2 is the same, the projection on the horizontal plane; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 1; figure 5 - section bb In figure 1.

The gateway consists of the upper 1 and lower 2 reservoirs, the upper 3 and the lower 4 lock chambers, a tunnel 5 connecting the chamber 3 with an inclined shaft 6, which on the other hand is connected to the chamber 4, the damper 7 separating the chamber 3 from the reservoir 1 damper 8 separating chamber 3 from tunnel 5, damper 9 separating tunnel 5 from shaft 6, damper 10 separating shaft 6 from chamber 4, and damper 11 separating chamber 4 from reservoir 2, aqueduct 12, connecting reservoir 1 with reservoir 2 and having a main hydroturbine 13 on the same shaft with the main generator 14, flaps 15-18, which can block conduit 12, connecting holes 19-21, which can connect conduit 12 respectively with chamber 3, shaft 6, chamber 4, conduit 22 connecting the upper and lower reservoirs and having an additional hydro turbine 23 on the same shaft with additional elektrogenei

RATOR 4, dampers 25-27, which can overlap WOCP 22, connecting holes 28 and 29, which can connect conduit 22, respectively, to Cameron 3 and the upper part of the shaft 6, water line 30, connecting the mine 6 to the reservoir 2 through the connecting hole 31 and shut off valve 32, connecting holes 33 and 34, connecting conduits 30 to conduit 22, conduit 35, connecting shaft 6 to conduit 12 through connecting hole 36 with shutters 37 and 38, blocking connecting openings of conduits 12 and 35, mooring walls 39 and 40 with respectively, in the upper and lower reservoirs for mooring the vessel 41 before and after sluicing, heated buildings 42 and 43 of sluice chambers 3 and 4, shock absorber protecting the front wall 45 of mine 6 from impact by vessel 41 when sluicing it, reinforced concrete walls 45 of the hull the tunnel.

The conduit 22 in the section from reservoir 1 to the opening 29 has the same cross section as the conduit 12, and in the rest of the section - 1.5 times smaller.

Hydraulic turbine 13 to electric generator 14 must Howl 1.4 times (1.3-1.5 times) more powerful than hydro turbine 23 and electric generator 24. Accordingly, 1.4 times larger will be the cross-sectional area of annuals 12 and 35 than water lines 22 and 30.

If there is an excess working volume of water in the upper reservoir compared to that required for the normal operation of this complex, this complex can Syt include a hydroelectric power station, working on draining the excess water from the upper reservoir to the lower one. The main parts of such a hydroelectric station (conduits 46, hydraulic turbines 47, electric generators 48, and flaps 49) are conventionally shown by a dashed line, since the hydroelectric station as part of the proposed

complex may be absent or be at the dam of the upper reservoir.

With the passage of the vessel through the gateway of the reservoir I in the reservoir 2, the device operates as follows.

The vessel 41 stops at the quay wall 39 of the chamber 3 with the raised

That flap 7 and lowered flap 8 so that its underwater part is located in chamber 3, and the top part - the captain chastnik with a ladder of the quay wall.

The bridge of the vessel 41 is lowered into the hull of the vessel and the vessel enters chamber 3 by rotating its propellers at low revs. The valve 7 is lowered, the valve 15 closes the conduit 12. At the same time, the valves 17 and 18 are opened and the water through the opening 19 leaves the chamber 3 and the conduit 1 2 and then through the hydro turbine I3 into the reservoir 2 "

Before the vessel enters the chamber 3, the valves 25-27 of the conduit 22 and the hydro turbine 23 with the electric generator 24 are generated and produce electric power of a given power due to the discharge of water from the upper reservoir to the lower one.

When the water level in chamber 3 reaches the water level in tunnel 5 and mine 6, gate 8 is raised (up to this point, water levels in tunnel 5 and mine 6 must be equalized and lift valve 9 is raised), gate 15 opens, and gate 16 closes and openings 19 and 20 are opened, resulting in the flow of water from the caper 3 through the tunnel 5 to shaft 6 and 6 and then through the conduit 12, rotating the turbine 13 with the electric generator 14 into reservoir 2. In this case, the water flow moves the vessel 41 out of the chamber 3 into the mine 6.

After the shutter 9 is lowered, the shutter 38 is opened (the shutters 17 and 18 are open) and the connecting hole 36 is opened. Water v.o of mine 6 through conduit 35 and turbine 13, rotating it, goes into conduit 12 and further into reservoir 2.

When the water level in the mine 6 becomes equal to the water level in the chamber 4, the valve 10 is raised, the opening 21 opens, the valves 17 and 38 open, the valves 15-37 open and the water from the reservoir 1 through the turbine 12 and 35 is created through the turbine 13 and from the ottoman 6 to the chamber 4 n, through the opening 21 in the reservoir 2, through the flow of water. The vessel 41 moves from the mine 6 to the chamber 4 to the opening 21 and the valve 18 is closed. After this, the shutter 10 is lowered (throttle 516

17 is closed), the valve 18 and the opening 21 are opened and the water level in the chamber 4 is compared with the water level in the reservoir 2, after which the valve II is raised. Vessel 41 exits reservoir 2 and moors at berthing wall 40.

When the vessel passes from reservoir 2 to reservoir 1, the device operates as follows.

The vessel enters the lock chamber 4, the flap II lowers, the flap 18 closes, the flaps 15-17 open and water enters the chamber 4 through the hole 21. After the water level in chamber 4 is compared with the water level in the shaft 6, the flap 10 rises , the valve 32 and the opening 31 are opened, and the vessel from the chamber 4, carried along by the flow of water, enters the shaft 6. The valve 10 is lowered, the valve 17 and the opening 31 are closed and the valve 32 is opened, water starts to flow from the reservoir 1 through the conduit 12 to the mine 6 through hydro turbine 13.

Upon reaching the water level in the mine 6, the water level in the tunnel 5 and chamber 3 (valve 8 remains elevated when the vessel is lowered) valve 9 is raised, valve 25 and 26 are opened, valve 15 is closed, water from the upper reservoir through the conduit 22 through opening 29 enters shaft 6 and chamber 3 through openings 19 through conduit 12 through hydro turbine 13 leaves into lower reservoir 2. From shaft 6 to chamber 3 through tunnel 5, water flow occurs, with which vessel 41 moves from shaft 6 through tunnel 5 to chamber 3

After the vessel enters the chamber 3, the slider 8 is lowered, hole 29

28 °

it closes, damper 27 opens and hydro turbine 23 begins to work with electric generator 24 when water passes through conduit 22 from the upper reservoir to the lower one. At the same time, the flap 15 opens, the flaps 17 and 18 are closed, and water flows from the upper reservoir

0 into chamber 3 until the water level in chamber 3 reaches the water level in the upper reservoir.

After raising the water level in chamber 3 to the water level in the reservoir

5 1, the flap 7 is raised, and the vessel 41 exits into the reservoir and is moored at the quay wall 39.
