Definitions

  • the invention relates to hydraulic engineering and can predominantly be used in hydrotechnical dust structures with a large width of a passage opening, e.g. are used in protective dikes that are built near large port cities to protect against flooding.
  • a special feature of such hydrotechnical structures is that several bluff bodies have to be attached to the width of the passage opening and work independently of one another.
  • a hydro-technical dam structure (DE-A-3433966) with vertical weir pillars spaced apart from one another by the width of a passage opening, extended baffles, which are connected in the middle to bearings and are arranged rotatably about a vertical axis with respect to these bearings, and with means for holding each Bluff body compared to the storage in its working position, which is perpendicular to the axis of the passage opening, and in its non-operating position, which is pivoted by 90 ° relative to the working position.
  • a disadvantage of this hydrotechnical structure is the presence of the bluff bodies distributed across the width of a passage opening in their opening position, which complicate the shipping conditions in such a passage opening in that these bluff bodies can be rammed by ships.
  • a hydro-technical dam structure (US-A-3756032) with a passage opening and at least one bluff body for closing off the passage opening, which contains an internal cavity, on its base with the aid of a horizontally extending axis with a bearing arranged below the water level, specifically connected to the weir base and rotatably arranged about said axis, as well as with a means for supplying air into said inner cavity for swinging out the bluff body and with a niche in the weir base for accommodating the bluff body.
  • a bluff body does not interfere with navigation through the passage opening, because when the passage opening is open, it is accommodated in a niche in the weir base.
  • the niche has relatively large dimensions in plan view. This is due to the fact that the dimensions of the niche depend on the dimensions of the baffle wall of a bluff body, which in turn depends on the depth of a passage opening; that reach 20 m and more, and are caused by the angle of inclination of a bluff body (approx. 45 °) in its working position. These relatively large dimensions of the niche increase the costs for the hydrotechnical structure, which are associated with the manufacture of the niche, as well as its operating costs, which are due to the fact that a relatively large area of the niche has to be cleaned of alluviums.
  • this hydrotechnical structure has a relatively high metal expenditure. This is associated with the fact that a hydrostatic load on the bluff body, which is caused by a water level gradient between the upper and lower water and is absorbed by the bluff body, is compensated for by immersing this bluff body as a result of its swinging out towards the underwater.
  • the angle of rotation of the bluff body is increased, the vertical distance of its top edge from the bearing (the weir base) is significantly reduced, the amount of the reduction in said distance being directly dependent on the height of the bluff body, i.e. on the distance from the base surface of the bluff body and its edge opposite the base.
  • the bluff body should have a height reserve in order to ensure a necessary locking height of the passage opening, so that a reduction in the said distance when swiveling out is compensated for, ie it has an increased metal expenditure.
  • the invention has for its object to provide a hydro-technical dam structure, in which the storage is carried out and connected to the weir sole so that the dimensions of the niche are reduced in plan view, thereby reducing the construction and operating costs of the hydrotechnical structure and the metal cost of the hydrotechnical structure can be reduced.
  • This task is in a hydrotechnical dust structure with a passage opening, a bluff body to block the passage opening, which contains a cavity connected to the water medium and on its base with the help of a horizontal axis with a storage located below the water level and connected to the weir bottom in connection stands and is pivotally mounted about said axis, a means for supplying air to said inner cavity for pivoting the bluff body and with a niche in the weir sole for accommodating the bluff body according to the invention solved in that the storage is designed as an additional bluff body, which with the Weir sole connected via an intermediate frame by means of a joint arranged on the underwater side in order to pivot said joint in a vertical plane and with the possibility of being accommodated in said niche in the weir sole and of the S
  • the center of gravity of said bluff body which has an internal cavity, is offset from said horizontally arranged axis towards the underwater, the hydrotechnical accumulation device providing a means for rotating the additional bluff
  • the additional bluff body picks up in the position extended from the niche and held in relation to the weir base and transmits via the intermediate frame to the joint that part of a hydrostatic pressure which, in the case of a water level gradient between the upper and lower water, is arranged horizontally below the arrangement level Axis works.
  • the additional bluff body remains immobile.
  • said bluff body which has an internal cavity, absorbs that portion of the hydrostatic pressure which acts above the arrangement level of the horizontally arranged axis.
  • this bluff body is significantly smaller than the height of the bluff body described in the technical solution from which the invention is based, the bluff body can have a smaller height reserve, as a result of which its metal expenditure and the metal expenditure for the entire hydrotechnical structure are reduced .
  • Reducing the required dimensions of a niche lowers the construction costs of a hydrotechnical structure, which are connected with the manufacture of the niche, and its operating costs, which result from the fact that the niche has to be cleaned of alluvial deposits.
  • the distance of the base surface of the bluff body having an inner cavity from the edge of this bluff body opposite this base surface is not less than the distance of this base surface from the joint.
  • This distance ratio ensures full coverage of the niche in the arrangement of additional bluff body, intermediate frame and actual bluff body accommodated therein, thereby leading into the niche when the passage opening is open no precoat can reach.
  • the buoyancy of the bluff body having an inner cavity in the air-filled cavity exceeds the total mass of the additional bluff body and the intermediate frame, the bluff body having said cavity having a cavity and a means for supplying air as a means for pivoting out the additional bluff body serve this cavity.
  • This structural design of the hydrotechnical structure is the simplest, because it does not require a separate means for pivoting out the additional bluff body.
  • the additional bluff body is provided with a buoyancy means, the buoyancy of which is smaller than the total mass of the additional bluff body and the intermediate frame.
  • This buoyancy means allows a buoyancy of the bluff body having an inner cavity to be reduced, which is necessary to ensure that the additional bluff body is pivoted out and consequently prevent the volume of this cavity or the metal expenditure of the bluff body.
  • the hydro-technical dam structure comprises a bluff body 2 arranged in a through opening 1 (FIG. 1), which has an inner cavity 3, and an additional bluff body 4.
  • the bluff body 4 has a curvilinear shape in vertical cross section, its convex surface facing the headwater 5 is, and is connected via an intermediate frame 6 to a weir sole 7 by means of a joint 8, which is offset from the bluff body 4 towards the underwater 9 is.
  • the bluff body 4 can also have a different shape in vertical cross section.
  • the joint 8 is designed such that it ensures that the bluff body 4 swings out into an operating position in a vertical plane.
  • the bluff body 4 has a cavity 10 which is filled with a medium (not shown), the specific weight of which is smaller than the specific weight of water, for example with polystyrene or air.
  • a volume of the cavity 10 and a medium filling this cavity 10 are chosen so that the total buoyancy of this cavity 10 and said medium is a little less than the total weight in water of the bluff body 4 and the intermediate frame 6.
  • the bluff body 4 can also have no cavity 10.
  • the additional bluff body 4 is a storage for the bluff body 2, which is connected to it at its base 11 by means of a horizontally arranged axis 12 so that the two bluff bodies 2 and 4 about the axis 12 and the joint 8 in the same vertical plane are rotatable.
  • an opening 13 is made, past which the inner cavity 3 communicates with the surrounding medium.
  • a distance "a" between the base surface 11 of the bluff body 2 and the edge of this bluff body 2 opposite this base surface 11 exceeds a distance "b" between this base surface 11 and the joint 8.
  • a niche 14 is designed for accommodation the bluff body 2 and 4 is determined.
  • the dimensions, geometric shapes and mutual position of the bluff body 2 and 4 are based on known calculation methods based on the fact that the center of gravity "c" of the bluff body 2 remains at any pivoting angle of this bluff body from the axis 12 to the underwater 9, and under the condition of their compact accommodation in the niche 14 calculated.
  • In the lower part of the bluff body 4 there is an extension 15 which engages with a stop 16 on the weir sole 7 when the bluff body 4 is in a position extended from the recess 14.
  • the approach 15 and the stop 16 together form a means for holding the bluff body 4 relative to the weir sole 7 in its position extended from the niche 14.
  • the hydrotechnical structure contains a means (not shown) of a generally conventional construction for supplying compressed air to the inner cavity 3 of the bluff body 2 to ensure its pivoting about the axis 12.
  • the maximum buoyancy of the bluff body 2 in the cavity 3 filled with compressed air exceeds the total weight in water of the bluff body 4 and the intermediate frame 6, whereby the bluff body 2 can serve as means for pivoting the bluff body 4 around the joint 8.
  • a means for pivoting the bluff body 4 around the joint 8 can be e.g. hydraulic, pneumatic or other drive can be used.
  • the hydrotechnical accumulation works as follows.
  • the bluff bodies 2 and 4 and the intermediate frame 6 are located in the recess 14. Since the distance "a" between the base surface 11 of the bluff body 2 and the edge opposite the base surface 11 is the distance "b" between this base area 11 and the joint 8, the niche 14 is completely covered from above by the bluff body 2, as a result, practically no precoat will get into the recess 14.
  • the inner cavity 3 of the bluff body 2 is filled with water. If it is necessary to seal off the passage opening, for example in the event of a risk of flooding, compressed air is fed into the inner cavity 3 of the bluff body, which displaces the water out of the cavity 3 through the opening 13.
  • the bluff body 2 begins to rotate about the horizontally arranged axis 12. The more compressed air is introduced into the cavity 10, the greater the buoyancy of the bluff body 2, it begins to emerge and takes the additional bluff body 4 with it, which rotates together with the intermediate frame 6 around the joint 8.
  • the bluff body 4 is pivoted about the joint 8 and gradually moves out of the niche 14 until the extension 15 on the lower part of the bluff body 4 against the stop 16 on the weir base 7. As a result, the passage opening is blocked off. Since the cavity 10 is provided with a buoyancy in the additional bluff body 4, buoyancy of the bluff body 2, which is required for lifting the bluff body 4, is substantially reduced.
  • the bluff body 4 With the blocked passage 1 (Fig. 1) and with a water level gradient between the upper water 5 and the lower water 9, the bluff body 4 remains immobile and absorbs that portion of the hydrostatic pressure which acts below the arrangement level of the axis 12 and transmits it via the Intermediate frame 6 on the joint 8. The bluff body 2 absorbs only that portion of the hydrostatic pressure which acts above this arrangement level of the axis 12.
  • the passage opening 1 is opened when there is no water level gradient between the upper water 5 and the lower water 9.
  • air is allowed to escape into the atmosphere from the inner cavity 3, as a result of which the surrounding water penetrates into this cavity via the opening 13; the bluff bodies 2 and 4 rotate around the ashes 12 or the joint 8, fold up and lie in the recess 14.
