Water intake structure on debris flow rivers

 

(57) Abstract:

The invention relates to hydraulic engineering and relates to a device for collecting water from the debris flow rivers. Water intake structure on debris flow rivers contains spillway retaining wall with steep drainage, the target of which is the water intake hole. River gate is made with beveled relative to the horizontal plane of the lower part placed in the line of the steepest part of the work of the dam, and the construction is done with proryvnym hole and overlying the flat valve gate connected a flexible shaft with a float and placed in the lower part of the river gate. On the surface of the cool work provided by cycloidal conductors. The water intake hole is made in the form of a cone, on the inner surface of which is provided with a curvilinear spiral grooves, longitudinally placed from highest to its lower section and connected with the annular groove in the smaller section. The construction provides reliable operation in all weather conditions due to the separation of a multiphase environment and clarification thread. 3 Il.

The invention relates to the field of hydraulic engineering and touches the device is 03 B 1/00, Bull. N 16, 1972), including the recipient and shutter balances, the recipient is made in the form of a rectangle of constant width and slope of the tray, the walls of which are formed openings, and the gate is made in the form of movable shutters supplied to the receiving trays curvilinear forms that are installed with the possibility of rotation around the vertical axis.

The disadvantage of this abstraction is the silting of the water intake gallery after the passage of the debris flow and the need for additional cleanup costs and incomplete automation.

Known water intake structure on debris flow rivers (see and.with. N 549552, MKI E 03 B 1/00, bull. N 9, 1977), containing spillway retaining wall with steep work, the target of which is a water-intake hole, river gate, made with beveled relative to the horizontal plane of the lower part and is placed in alignment with the steepest part of the work of the dam, and the construction is done with proryvnym hole and overlying the flat valve gate connected a flexible shaft with a float and placed in the lower part of the river gate.

The disadvantage of this diversion structure is a fence unclarified them water after the invention, is to increase reliability and ensure the fence most of the clarified water from the river.

The technical result is achieved by the fact that water intake structure on debris flow rivers containing spillway retaining wall with steep work, the target of which is a water-intake hole, river gate, made with beveled relative to the horizontal plane of the lower part and is placed in alignment with the steepest part of the work of the dam, and the construction is done with proryvnym hole and overlying the flat valve gate connected a flexible shaft with a float and placed in the lower part of the river gate, is on the surface of the cool work posted by cycloidal conductors in the form of a flexible spiral guide, and the water intake hole is made in the form of a cone, on the inner surface of which is formed a curved spiral grooves, longitudinally placed from its highest to its smaller cross-section and connected with the annular groove made in the smaller base.

In Fig. 1 shows the proposed water intake structure on debris flow rivers, longitudinal section, Fig. 2 - view from downstream, and Fig. 3 - times what ukami and the annular groove.

Water intake structure includes spillway retaining wall with steep work 1, the receiving hole 2 located in the abutment of the dam at the site cool work, river gate-machine 3, is made with beveled relative to the horizontal plane of the lower part and is placed in alignment with the steepest part of the work of the dam, washing hole 4 located in the lower part of the river shutter 3 and filled his flat valve shutter 5. River gate 3 via truck rod 6 fixed to the axle 7. Flat valve shutter 5 leaching hole 4 is connected to the float 8 flexible shaft 9. On the steep surface of the work 1 posted by cycloidal conductors 10 in the form of a flexible spiral guides. The water intake hole 2 is made in the form of the diffuser 11, on the inner surface of which is formed a curved helical grooves 12, placed longitudinally from its highest to its smaller cross-section and connected with the annular groove 13 made in smaller sections. Annular groove 13 is communicated with the lower water through pipe 14, the end of which a valve 15.

Water intake structure operates as follows.

With the passage of the river flow iget additional load, under the influence of the river which the shutter 3 is opened by rotation about the axis 7 in the direction downstream, passing mud flow. After the passage of the flow, in the presence of water with a low saturation, sediment, river shutter 3 is closed (automatically or involuntarily), and the water level in front of him will rise to the settlement, providing for the withdrawal of water through the water intake port 2. River water through the water intake port 2 enters the diffuser 11, on the inner surface of which is formed a curved helical grooves 12, in which it is twisted, acquiring a helical movement. When this solid particles, failed to pass through the river gate 3 in the transitional periods are discarded to the periphery, twisted into a curved helical grooves 12, escalated face abraded, coagulated and down in the annular groove 13. Accumulating in the annular groove 13 of the solid particles on the pipe 14 when the open valve 15 is discharged in the form of pollution in the lower reach. Located on the steep surface of the work 1 cycloidal conductors 10, made in the form of a flexible spiral guides ensure the formation of the initial spin of the incident it pookalam and due to the flexible properties of the material.

With the increase of the calculated water level opens flat valve shutter 5 leaching holes 4 by means of the float 8 and the flexible rod 9. It involves dropping unnecessary costs of the water and transported (due to bevel the lower part of the river gate 3) to promiseme hole 4 of the sediment. With further increase in water level river reopens the shutter 3.

Water intake structure proposed design creates a storage volume upstream of the dam for the deposition of sediment during the first period of the reformation channel, reaching a steep drainage downstream, providing a full wash load at the site of the location of the bolt-machine, thereby increasing reliability in combination with intense swirling flow of water in a centrifugal vibratory field, effectively ensuring the separation of a multiphase environment under varying hydrodynamic characteristics of the river flow at variable Ladispoli and climatic conditions.

The originality of the proposed technical solution is to use the effect of swirl flow of river water to create a centrifugal vibratory field, provide agnosti water in any weather and climatic conditions.

Water intake structure on debris flow rivers containing spillway retaining wall with steep work, the target of which is a water-intake hole, river gate, made with beveled relative to the horizontal plane of the lower part and is placed in alignment with the steepest part of the work of the dam, and the construction is done with proryvnym hole and overlying the flat valve gate connected a flexible shaft with a float and placed in the lower part of the river gate, characterized in that on the surface of the cool work posted by cycloidal conductors in the form of a flexible spiral guide, and the water intake hole is made in the form of a cone, on the inner surface of which is formed a curved spiral grooves, longitudinally placed from its highest to its smaller cross-section and connected with the annular groove made in smaller sections.

Sump chamber bottoms are inclined in flow direction. Through section is located near the flushing check lock from lower pool side. The through section has inclination angle exceeding or equal to that of sump chamber bottom. Water accumulation tray is arranged upstream of flushing check lock transversely to water flow direction.
