The method of regulating the hydraulic flow pattern of the water and the device for its implementation

 

The invention relates to hydraulic engineering, namely to remedy various intakes, for example, from the river to the city of lunawada, from the ingress of debris, sediment and floating debris. To implement the method for controlling hydraulic flow patterns of water while reducing turbidity and the number of floating particles in the stream increase the angle of attack dynamic axis of flow regulators flow pattern by rotating in a vertical plane about the rotation axis, while increasing the turbidity and the number of floating particles in the flow to reduce the angle of attack. The device for implementing the method includes receiving the camera, the shutter and controls the flow patterns made with the possibility of rotation of the actuator, namely, in the form of filters that are installed with possibility of vertical movement about their axes located at the beginning of the filters in the water flow. The invention allows to adjust the hydraulic flow pattern of water in all water intake structure, not turbulizer advanced flow, eliminating unnecessary secondary flow, and extends the control range. 2 S. p. f-crystals, 2 Il.

The invention relates to gerot is dropping them in the garbage, sediment and floating debris.

A known method of regulating the hydraulic flow patterns of water, including accommodation for the circulation threshold vertical parallel threshold wall when the water level increase before the circulation threshold vertical wall move in the direction of the circulation threshold (A. C. of the USSR №1562395, MKI E 02 In 8/02, B. I. No. 17, 1990).

The disadvantage of this method is that in many hydraulic structures due to the large variability of hydraulic regimes, such as storm water conduits, there is no possibility to create a sustainable circulation before the threshold, also this method is unacceptable for streams with a high content of floating objects, preventing or eliminating altogether the movement thresholds relative to each other.

Closest to the proposed invention the technical essence is a way to automatically adjust the hydraulic flow patterns at the water intake, when decreasing the turbidity of waste water and increase the intensity of circulation of the thread before the threshold, and increasing the turbidity of waste water and reduce the intensity of the circulation flow at the threshold by turning the threshold relative to horizontally patterns of water flow, that in any situation, whether it is the established mode of construction or improvement of a perturbation on it, the water in the recipient gets only from the upper layers, which are most heavily saturated with driftwood and debris.

Known apparatus for implementing a method for controlling hydraulic flow patterns of water containing circulating threshold set at an angle to the axis of the watercourse, and the threshold is made of sections that are installed with the possibility of rotation of the actuator relative to the horizontal axis, located in the lower part of the section (A. C. of the USSR №1114730, MKI E 02 In 8/02, B. I. No. 35, 1984).

The disadvantage of this device is that it creates a sustainable circulation flow only at certain speeds it unhealthy in high turbulence in the flow and at low energy in the flow, which significantly limits the scope of its application.

The closest in technical essence is the device controlling hydraulic flow patterns containing circulating threshold of river water intake and a vertical wall that is installed with the possibility of vertical and horizontal movement perpendicular to the circulation threshold (A. C. the USSR No. 1562 the e sediment and floating inclusions in flow is possible only in low range cost changes speeds and accordingly the water level upstream of the structure. In other cases, or formation of a stable vortex or channel between the door and the wall is so great that drifts freely fall into the recipient cell. Also a very complex kinematic diagram of the device must ensure vertical and horizontal, perpendicular to the circulation threshold, the movement may not be executed at all if the jamming of the fin.

The technical solution of the present invention is to expand the range of regulation and improving efficiency by reducing the inflow of sediment and floating impurities from the stream to the receiving chamber of the diversion structure, as well as increased reliability.

The task is achieved by the fact that according to the method of regulating the hydraulic flow pattern mainly in the collection of water from a watercourse, while reducing turbidity and the number of floating particles in the stream increase the angle of attack dynamic axis of flow regulators flow pattern by rotating in a vertical plane about the rotation axis, while increasing the turbidity and the number of floating particles in the flow and consequently reduced, and the device for implementing the method, including vodopriveda filters, installed with possibility of vertical movement about their axes located at the beginning of the filters at a flow of water.

The method is characterized by the fact that when water from a watercourse, when reduced turbidity and the amount of floating particles in the flow, increase the angle of attackdynamic flow axis, the filters by rotating in a vertical plane, while increasing the turbidity and the number of floating particles in the flow, on the contrary, reduce the angle of attack that allows you to extend the range and simplify the regulatory process.

Thus, the claimed method meets the criterion of “novelty”. Comparative analysis of the proposed method with other decisions in this area failed to reveal any sign that distinguish the claimed solution to the prototype. This allows to make a conclusion about its compliance with the criterion of “inventive step”.

Comparative analysis of the claimed device with the prototype shows that it controls flow pattern made in the form of filters that are installed with the possibility of vertical movement and the rotation axis of each filter set at the beginning of it, the current of the water. Thus, the claimed device implementing other solutions in this area failed to reveal any sign, distinguish the claimed solution to the prototype that allows to make a conclusion about its compliance with the criterion of “inventive step”. It is used as a device when the withdrawal of water from watercourses filters that are installed with the possibility of vertical movement when the axis of rotation of each filter installed at the beginning, current water, allowing you to reach controls all water intake structure at the expense of adequate response to the change of process input parameters, such as turbidity flow and the amount of floating particles in it.

The invention is illustrated by drawings, Fig.1 shows a water intake structure with a device for regulating the hydraulic flow patterns, longitudinal section; Fig.2 - section a - a of Fig.1.

The device comprises a water-receiving chamber 1, which represents a rectangular gallery of variable height, which is below the natural bottom of the stream or channel. Water-intake chamber 1 has an elongated shape, is located along the axis of the stream and is used for accumulation of purified water. Filters 2 made in the form of plates, as an example of porous concrete that overlap the receiving chamber 1 and serve simultaneously is the beginning of each filter is set to axis 3, and the end plate of the filter is in the upper part of the rod 4 with the actuator 5, carried out from the bridge 6, and at the bottom - skimming wall 7, preventing the flow of water past the filter. Inclined flat shield 8 is used to regulate the flow of water from the water intake chamber 1.

A device for controlling hydraulic flow patterns of water works as follows: water, moving along the bed of a natural or artificial watercourse, full of sediment and floating debris. The principle of the construction based on the use of filtration, inertial properties of the flow. To increase the filter by transferring the kinetic energy of mastrodicasa flow into potential energy of pressure fluid filter plate 2 on the axis 3 by means of the rod 4 and the actuator 5, carried out from the bridge 6 will be elevated, increasing the angle of attack dynamic axis of flow to the filter 2, and skimming the wall 7 will prevent the flow of water past the filters. Decreasing the filter, on the contrary, the angle of attackdynamic axis of flow to the filter 2 must be reduced. Changing the position of the filter 2 to the dynamic flow axis, the absence of any obstacles in the flow contributes to the innite is of such factors and adequate exposure of the device to these changes. Purified from sediment and floating impurities water from the water intake chamber 1, having an inclined flat shield 8, enters the water.

The proposed method of regulating hydraulic flow patterns of water is as follows: at steady state hydraulic parameters within the water body, such as the level of water on the structure, the speed of movement of the water, the turbidity and the amount of floating inclusions, naturally, will be established technological parameters of the structures, such as the angle of attack of the filter 2 to the dynamic flow axis and, as a consequence, the actuators 5 and the amount of opening of the flat of the shield 8. With decreasing water level on the structure and, consequently, reduce the amount of sediment and floating particles in the stream in order to maintain the preset parameters on the water it is necessary to increase the angle of attackdynamic axis of flow to the filter 2, which is achieved by raising the rod 4 by means of the actuator 5, carried out from the bridge 6, one end of the filter 2 in relation to the other, attached to the axis 3. When the water level increase in the construction of all actions it must be the opposite of the above. When any mode is Yat to work out these perturbations and provide planned water supply through a flat shield 8.

The proposed method of regulating hydraulic flow patterns of water, including changes in the level upstream of the hydraulic structures and carried out by adequately changing the angle of attackdynamic axis of flow of water to the filter 2, when the change of turbidity and floating particles in the flow, allows you to extend the range and simplify the regulatory process, to prevent floating particles in the water intake chamber 1, and to increase the reliability of the entire structure, since the flow does not create any obstacles and it can without resistance to transport any inclusion of transit.

A device for controlling hydraulic flow patterns of water, including the water intake chamber, the shutter and controls the flow pattern, made in the form of filters, and the filters are installed with the possibility of vertical movement, as the axis of rotation of each filter is located at the beginning of it, current water, simply by design, reliable in operation, allows you to reach controls all water intake structure, not turbulizer advanced flow, eliminating unnecessary secondary flow, is required when blood circulation to the:2mm;">Claims
