Protective oil barrier
(57) Abstract:Usage: hydraulic construction, in particular hydraulic structures, moored vessels or other floating objects as a protective device against extreme impacts of solid ice fields. Protective oil barrier contains Bons, located in the middle of the ice on the surface of the water, the boom is made of two elements in contact with each other on an inclined platform through the gasket, which is destroyed when the load of the ice reaches the value at which the device should "work", followed by a shift of the elements of the boom on an inclined platform relative to each other. The area of the strip prior to the installation of fences or in the course of its operation can be changed. The coefficient of friction on the contact surfaces of the elements of booms and pads can be changed. Can be changed the angle of inclination of the contact surfaces of the elements of booms and pads. In addition, to reduce the magnitude of the impact on the protected structure (object) at loads from ice, not exceeding the limit of the "operation" of the device, the elements of the boom can be made malleable. In connection with the provision of the ruin is on the impact of solid ice fields of a thickness exceeding 0,8-1,0 m The device enables a strict definition and regulation of the load from the ice in which the device "works" (is the destruction of the ice). Regulation limit operation can be performed by changing the angle or square pads, and replacing it with another with a different ultimate strength in compression. 4 C. p. F.-ly, 1 Il. The invention relates to hydraulic construction and can be used for hydraulic structures, moored vessels or other floating objects as a protective device against extreme impacts of solid ice fields.The known device for the protection of hydraulic structures from the effects of ice made in the form of vertical or inclined ice-cutters (Peschansky, I. C. Lagoudera and hladotehnika / Ed. 2nd, supplementary and processed, Leningrad Hydrometeorological publishing house, 1967,S. 404-407). After a slight indentation of ice-cutter to the edge of the ice appears ahead of the crack. As further advancement of the ice is breaking consoles in the form of triangular maps. In case of considerable thickness or the low strength of ice fracture may result from deformation of the slice. These devices on the s solid construction or for protection from the effects of ice fields less effective and in cases when according to the technological requirements invalid protrusions from the plane of the structure (object),not possible, for example, for moored vessels, berthing facilities, floating docks, etc., in Addition, these devices due to their high cost is not - it is advisable to use for temporary protection structures (objects).Another known way of protection is the use of inclined walls (the Impact of ice on marine structures shelf /Ed. by A. I. Korchagina/. M VINITI, 1988, S. 8-9). This event allows by changing the mechanism of destruction of ice (the ice breaks from the bend) to reduce load on structures (objects). However, for some structures (objects) using an inclined front faces unacceptable.It is known that in some cases, to protect structures (objects) from exposure to solid ice fields along the front surface is arranged polynya (Maina) (Michelle B. Ice loads on hydro-technical constructions / Per. s angl. M. Transportation, 1978,S. 26). But at the same time polynya forms a free surface in the ice box. This provoked the movement of ice in the side of the building (object). If a specific configuration of the hole is to the m to the structure (object). In addition,the event loses its effectiveness when there is ice movement greater than the width of the hole and has high maintenance costs.Known protective device containing a strip of foam or rubber placed between the outer surface of the structure (object) and ice perceiving deformation without transferring significant effort on the building (object) (ibid., S. 26). However, these pads also lose their effectiveness when the quantities of ice movement exceeding the maximum deformation of the strips.Known oil fence, containing bills in the form of logs, located on the surface of the water within the ice, which is the protective device from exposure to solid ice fields (ibid,s 26). Booms act as hinges and contribute to the destruction of the ice from buckling. Load protected structures (objects) are greatly reduced. This unit is adopted for the prototype.When the ice thickness in excess of 0.8-1.0 m, the decay of buckling does not occur and the use of booms of logs becomes impractical. Another disadvantage of the prototype is that the value navruzname definition and regulation.The present invention is the expansion of the scope of the protective device on the ice thickness of more than 0.8-1.0 m and enabling strict definition and regulation of the load from the ice in which the device "works" (is the destruction of the ice).To solve this problem in the known protective containment fence containing the boom is located in the middle of the ice on the surface of the water, these booms are made of two elements in contact with each other on an inclined platform through the gasket, which is permitted when the load of the ice reaches the value at which the device should "work", followed by a shift of the elements of the boom on an inclined platform relative to each other.The area of the strip prior to the installation of fences or in the course of its operation can be changed.The coefficient of friction on the contact surfaces of the elements of booms and pads can be changed.Can be changed the angle of inclination of the contact surfaces of the elements of booms and pads.In addition, to reduce the magnitude of the impact on the protected structure (object) at loads from ice, not exceeding the limit "creation cross section of the boom. Protective oil barrier contains Bons 1, located on the surface of the water in the ice 2. The boom consists of two elements: the top 3 and bottom 4, in contact with each other on an inclined platform through the gasket 5, the area of which can be changed, for example, by introducing new or additional padding.Can be modified coefficient of friction on the surface of the contact elements of the boom 3 or 4 and gasket 5, for example, by coating the contacting surfaces with special structures or by introducing between the elements of the boom 3 or 4 and spacers 5 plates or films 6 of the other material.To change the angle of inclination of the contact surfaces of the elements of the boom 3 or 4 gasket 5 may be provided with a regulating device 7. In addition, the tilt angles can be reversed by reversal of the boom 1 180o.Protective oil barrier works as follows. Before installing booms between the elements of the boom 3 and 4 introduces the strip 5 so that the friction elements of the boom 3 and 4 on the strip crown-rump length was:
where the angle of the strip 5 to the vertical;
And the area of contact ETL its inclination to the vertical line are chosen so that to
RSGA = Ncos(),
where N critical power transmitted on Bon 1 ice 2, in which the device is expected to work" (damage ice) limit "operation".In addition, the gasket material 5 is selected so that the coefficient of friction elements of the boom 3 and 4 on the destroyed gasket KhfTrphwas
Before installation and during operation, if necessary, for changes in these coefficients of friction of the contact surface can be coated with a special composition, as well as between them can be entered plates or film 6 of the other material.In addition, if the adjusting device 7 can be changed the angle of inclination of the contact surfaces of the elements of the boom 3 and 4 gasket 5.In accordance with the characteristics of protected structures (object) the boom 1 can be installed with an inclination of the strip 5 in the side of the building (facility), and from him.Protective oil barrier is installed on the surface of the waters, as a rule, prior to ice formation, thus, to be uniform marzenie boom 1 in the ice 2.Por the deposits are situated in the original position, or, if the elements of the boom pliable, they can warp and consequently reducing the load on the structure (object).When the load of the ice reaches the "trigger", is the destruction of the strip 5, and the top element bona 4 together with ice, behind, starts to hang on the lower element 3. Is the thrust of the ice. The ice located between the protective side rails and the protected structure (object), turn off from work and will not produce a significant impact on the protected structure (object).In connection with the provision of ice breaking from the vertical slice, followed by the thrust of the ice offer protective oil barrier provides protection from exposure to solid ice fields, including thickness of about 0.8-1.0 m the Design of the device enables a strict definition and regulation of the load from the ice in which the device "works" (is the destruction of the ice). Regulation limit operation can be performed by changing the angle or square pads, and replacing it with another with a different ultimate strength in compression.The proposed protective Bonobo osdate solid ice fields for such structures (objects), as the jetty moored ships, floating docks, floating nuclear power plants, etc., That barrier has low operating costs and cost, and high mobility. 1.
