For reasons that impede the achievement of specified following technical result when using the known device, taken as a prototype, is that in the known device the increased energy loss due to the large length of the inlet pipe water intake-water outlet chamber. In addition, the upper and lower faces of the input end of the pressure conduit is comprised of a large number of moving parts, which significantly reduces the reliability and lifetime of the whole structure.

The invention consists in the following.

In most cases, the receiving-water outlet chambers PSP and NA increased loss of energy flowing due to long water intake-water outlet chamber and a significant loss of energy due to friction of flow on the walls of this chamber. The proposed construction of water intake-discharge will significantly reduce the length of the water intake-water outlet chamber by increasing the angle of her astronote. Reducing the length of intake-water outlet chamber will reduce material consumption and cost of water intake-discharge, and all PSP or NA, and this miskitia the recipient will avoid device of a large number of moving parts, that will provide a solution to the problem of increasing the reliability and durability of the whole structure.

Effect: reduce the length of intake-water outlet chamber and due to this reduction of material consumption and cost of construction; energy loss reduction of flow in the receiving - water outlet chamber; reducing failures and downtime for repair; improving the reliability and durability of the whole structure.

This technical result in the implementation of the invention is achieved in that in the known device the recipient of the discharge, including water intake-water outlet chamber, a transition section and a penstock, a feature is that the penstock is equipped with photocontrolled plates, axes, thrust plates and locating lugs, and photocontrolled the pterygoid plates are made of profile material providing neutral buoyancy, and is provided with an axial hinges placed on one of the edges, through which photocontrolled plates are fixed on the axes, and photocontrolled plate placed on the axis on the side opposite to the receiving-water outlet chamber, and axis placement is pornoho conduit and the other party in the center of the pressure conduit between themselves, with the bearing plate secured to the wall of the pressure conduit and placed in areas touching the corners loose sides photocontrolled plates. Photocontrolled plate can be performed with bevel one corner loose side, forming a hard edge. Inside photocontrolled plate is made hollow, and the cavity provide neutral buoyancy. The bearing plate can be made in the form of a single ring, placed on the wall of the pressure conduit.

In the study of the distinctive features of the described water intake-discharge does not identify any known similar decisions regarding the use of the traditional design of water intake-discharge operating in the pumping mode.

The positive effect from the use of the invention is to avoid the generation of separation of the water flow from the walls of the water intake-water outlet chamber by providing a spin flow in the water-the water outlet chamber when operating in the pumping mode using photocontrolled plates. Moreover, in order to automatically turn on in the work (lifting) photocontroller. The proposed construction of water intake-discharge will reduce the energy losses of flow in water-the water outlet chamber at its work in the pumping mode, to reduce the length of the chamber and hence to reduce the material and construction costs, as well as to reduce the failure rate and downtime for repair, improve reliability and durability of the whole structure.

The drawings show: Fig. 1 shows the proposed receiving water-outlet, a longitudinal section; Fig. 2 is a longitudinal section of a plot of pressure conduit when working pumped in the pumping mode, and Fig. 3 is a plot of pressure conduit, a top view; Fig. 4 - section a-a in Fig. 2.

The water intake-discharge includes water intake-water outlet chamber 1, the transitional part 2, penstock 3, photocontrolled plates 4, 5, 6, and 7 wing-shaped profile made of material providing neutral buoyancy or from a heavier material, but with cavities. Photocontrolled plates 4, 5, 6 and 7 are provided with axial hinges 8, placed on one of the edges, through which photocontrolled plate placed on the axis 9, and the axes lie in a plane coincident with the plane of the cross-section e pressure conduit between them. Photocontrolled plates 4, 5, 6 and 7 is made with a bevel one corner loose side, thereby forming a thrust rib 12. In places touch the thrust rib 12 photocontrolled plates to the wall of the pressure conduit 3 posted by the bearing plate 11. In addition, in order to prevent the spread photocontrollable plate 5 in the lower working position, in the wall of the pressure conduit 3 is mounted locking the stop 10.

The recipient-outlet operates as follows.

When the water intake-water outlet in the turbine mode, water from the reservoir enters the water intake-water outlet chamber 1, the transition section 2, and then into the discharge conduit 3. Under the action of water flow 13 (13 - direction of water flow at the turbine mode), movably mounted on the axles 9 photocontrolled plates 4, 5, 6 and 7 wing-shaped profile are in a floating position in the direction of flow. Because photocontrolled plates have streamlined profile, they create favorable hydraulic conditions under which the pressure loss in the receiving waters-outlet least.

When the water intake-water outlet in the pump mode photocontrolled plates 4, 5, 6 and 7 under the action of a stream is a of Fig. 4 and the dotted line in Fig. 3. Free movement photocontrolled plates on the axles 9 provides axial hinges 8. Fixed position photocontrolled plates is achieved by the presence of the thrust plate 11, secured to the wall of the pressure conduit 3 places touch the thrust rib 12.

The presence of the locking stop 10 prevents rotation of the plate 5 in the lower non-operating position.

The device movably fixed photocontrolled plates provides a swirling flow, and this prevents the separation of the water flow from the walls of the water intake-water outlet chamber 1.

When the water intake-water outlet in the turbine mode photocontrolled plates 4, 5, 6 and 7 again automatically returned to the position indicated in Fig. 1.

The proposed solution is the recipient of the culvert does not allow separation of the water flow from the walls of the water intake-water outlet chamber by providing a spin flow that provides the energy loss reduction of flow in the chamber. This construction of water intake-discharge also allows you to shorten the length of the chamber and hence to reduce the consumption of expensive materials for manufacture and cost. Chrome is the durability of water intake-discharge chamber during operation.
