Description

The invention relates to hydraulic engineering and relates to the discharge of hydroelectric devices.

The mine drainage is known, in which the water intake tunnels are located at different levels in case of deposition of bottom holes with sediment or for the possibility of drawing water from different layers of the reservoir as it is used up (£ 1).

However, in this drainage device is not provided for quenching the energy of the flow, which reduces its efficiency.

Also known is the mine spillway containing the water supply channel, the shaft of the vertical shaft, divided. height-adjustable shelves, provided with holes and guides for dividing the flow of £ 2].

1 However, in the well-known mine spillway, the energy of the flow is not efficiently extinguished.

The purpose of the invention is to increase the efficiency of the quenching of the energy discharged childbirth.

This goal is achieved by the fact that in the mine spillway, including the water supply channel, the shaft of a vertical shaft, divided by height ²

Those shelves, equipped with holes 1 and guides for dividing the flow, made a dead-end tunnel, located on the same level with the water supply channel and equipped with a flow divider installed with the formation of tunnel-dampers connected with. vertical shaft inclined galleries with the provision of tangential flow inlet to it.

In addition, with a multi-tiered arrangement of water supply channels, the quenching tunnels of adjacent tiers are connected by vertical channels.

four

Calling tunnel-dampers 9. Tunnel-dampers 9 are connected to the vertical shaft 3 by inclined galleries 10 with the provision of a tangential supply of flow to it. With a multi-tiered arrangement of power supply channels 5, 1 tunnel extinguishers 9 of the adjacent tiers are connected by vertical channels 111 Shelves 4 are made in the form of a tray 12 · with sloping walls that block the shaft to the holes 5 for drainage in No. da. Water supply channels 1 are equipped with adjustable valves 13 ..

Spillway works as follows.

At different levels of water in the reservoir-15 Nilishche, the water enters the intake canals 1, located at different levels, then goes to the shelves 4. Here the molasses is divided. Part of the flow through the holes) 5 goes to the bare shelves, which can be made several times in the shaft of the shaft between the receiving holes. This part of the flow passes through all the shelves 4 and enters the drainage channel 14.

The second part of the flow passes from the water intake channels 1 to the dead-end tunnels 7, then to the tunnel-dampers ’

9, and through inclined galleries 10 enters the shaft of the shaft, and along the vertical "channels 11 - into the lower tier. This part of the flow also enters the shaft of the shaft and enters the drainage channel 14.

With the passage of water flows, they are collided, discharged, developed ’’

mouth, due to what is effective quenching of the energy discharged water.

Claims (2)

Claim 1. Mine spillway, including ^; water supply channel, vertical shaft, divided by height by shelves, provided with holes and guides for dividing the flow, characterized by the fact that, in order to increase efficiency, a dead-end tunnel is installed in the mine spillway, flush with the water supply channel and supplied a flow divider installed to form tunnel dampers connected to a vertical shaft by inclined galleries with the provision of a tangential supply of flow to it. 2 "Spillway pop. 1, which is different from the fact that, in order to increase efficiency with the multi-layered arrangement of water supply channels, the damper tunnels of adjacent tiers are connected by vertical channels.
