    专利说明:

    The invention relates to hydraulic engineering and can be used to protect offshore structures from being destroyed by ice.
    A device is known for protecting 5 hydraulic structures from destruction by ice, including pile supports and a grid made of vertical chains, one end rigidly mounted on the bottom console of pile supports, and the other connected to shock absorbing devices mounted on the upper arms of the H0X pile supports Q.
    The disadvantage of this device is that it only allows to reduce the dynamic loads on the structure from the effects of ice, without destroying it.
    It is also known a device for storing a structure against ice breaking, including a mechanism installed on a support for breaking ice.
    The mechanism for breaking ice is designed as a flow former with
    nozzles, capturing the bottom warm layers of water and supplying water with a powerful jet to crushable ice fzj.
    The disadvantage of this device lies in its considerable cost and power consumption of breaking ice.
    The purpose of the invention is to reduce the cost of the device and energy consumption.
    The goal is achieved by the fact that the device is equipped with a cart mounted in horizontal guides, and the mechanism for breaking the ice is mounted on the cart and is designed as a milling cutter, the axis of which is placed vertically
    The guide can be made in the form of a ring mounted on a support with the possibility of vertical movement.
    FIG. 1 shows a drilling rig, equipped with devices to protect it from destruction by ice, axonometrics; in fig. 2 - mechanism for the destruction of ice, side view; FIG. 3, section A-A in FIG. 2; in fig. 4 — support of the drilling rig with a mechanism for breaking ice mounted on a support with the possibility of vertical displacement; axonometrics in FIG. 5 support of a drilling rig with a mechanism for breaking ice, having a jet drive, axonometrics; in fig. 6 is a top view of the mechanism for breaking the ice, made in the form of a chain with teeth; in fig. 7 view B in FIG. 6; in fig. 8 - the mechanism for the destruction of ice, mounted on a support with the possibility of vertical movement by means of a rail pair; in fig. 9 - a drilling rig with a mechanism for breaking ice mounted on a guide placed around the supports of the drilling rig, axonometrics; in fig. 10 a device to protect the buoy and the tanker from exposure to ice, axonometrics; in fig. 11 — A device for protecting a moored vessel is exposed to ice. The device (Fig.) Contains the mechanisms 3 installed on the supports 1 of the drilling rig 2 for breaking the ice k. Mechanism 3 Sfig. 2 and 3) made in the form of a sleeve 5 with flanges 6 installed by a key 7 on the support 1 with the possibility of vertical movement by some drive (not shown) interacting with the sleeve 5 through the rods 8. A sleeve 9 is fitted with a sleeve 9 s Flanges 10 with the possibility of rotation by the electric motor 1; The liner 5 is a rotation guide for the sleeve 9. Between the flanges 10 there are mounted cutters 12 with electric motors 13. Made in the form of cylinders with teeth It. A milling cutter 15 is installed under the lower flange 10. The device operates as follows. In the ice period, an electric motor -11 is turned on, which provides rotation of the sleeve 9. At the same time, the sleeve 5 is driven by KOTOpoj-o the sleeve 5 with the sleeve 9 is lowered, cutting the ice cutter 15 around the support 1 by the cutter 15 electric motors 13 cutters 12 are turned on. The cutters 12 teeth 1 destroy ice i, forming a body of water around support 1. When ice 4 moves to the drilling rig 2, the cutters 12 cut a track k in the ice field and the ice k passes by the support 1 without any force effect on it. The mechanism 3 of FIG. l may be made in the form of a sleeve 16 with a spiral groove 17 mounted on the support 1 by means of a pin 18. Between the flanges 19 (the lower one is not shown of the sleeve 16, the milling cutters 12 with electric motors 13 are mounted. The sleeve 16 is connected by rods 8 with its vertical movement ( not shown;). When vertically moving the sleeve 16, it rotates around the support 1 due to the interaction of the pin 18 with the groove 17. Otherwise, the operation of the device does not change. Mechanism 3 (Fig. S) can be made in the form of two cutters 12 installed between rings 20 and i | t their nozzles 21 are directed in different directions. The tooth 1 of the cutters 12 can be fixed obliquely. Under the action of the working medium emanating from the nozzles 21 of the cutter 12 rotates to the cutting side, destroying the ice k around the support 1. Mechanism 3 (Fig. 6 and 77) be made in the form of a roller chain 22 with teeth 1A mounted on the supporting element 23 by means of a driving pulley 2t placed on the axis 25 and driven (not shown). Teeth 1 have different height and length and are placed along the chain 22 alternately. Ice k is struck alternately, then with long, then short teeth 1. High and short teeth destroy the ice, and long and low teeth remove ice from the hole. Cutter 12 (Fig. 8 can be mounted on support 1 by means of a toothed rack 26 fixed to support 1 and a ring 27 with a gear wheel (not shown) The cutter can have a tooth 1 located both on its cylindrical surface and on the face ones. from cutter 12 moves reciprocally along support 1 to produce ice breaking. To protect multi-support drilling rig 2, cutter 12 can be placed on a carriage 28 mounted in guides 29 which are fixed to unit 2 around its perimeter. Rotary cutter 12 moves around installation 2 by means of guides 29 and carts 28 and destroys ice, forming a body of water around installation 2.
    The mechanism 3 (Fig. 10 can be mounted on the mooring barrel 30 having guides 29. The carriage 28 is connected with the guides 29 with the boom 31. At the end of which the milling cutters 12 are mounted. The carriage 28, and with it the boom 31, oscillate , cutting through the cutters 12 in the field of Ice 4, moving to the mooring barrel 30, the track 4, thereby protecting the mooring barrel 30, as well as the vessel 32 moored to it from the impact of ice k on them,
    Mechanism 3 (Fig. 11) can be mounted on vessel 32 and protected from the effects of ice 4 on the crust. For this purpose, 32 are fixed on the bow of the vessel (control 29 with trolley 28, on which cutters 12 are mounted. When moving cart 28 along guides 29 cutters 12, crush ice k, forming an open water path in the field of moving ice.
    Such an embodiment of the device allows reducing its cost and energy consumption.
