    A shield for protecting a well head and functional modules in an under sea station comprising a composite cushion formed from a floor 6 made from a material less dense than water, such as a plastic material or treated wood, and resting on a perforated metal sheet or grid 7, removably fixed by means of deformable feet 4 to a horizontal plate 1 mounted at the top of the module to be protected and having at the position where the guide column 2 passes an opening in which is welded a sleeve 14 capable of sliding along said guide columns 2. In a shield for protecting a module provided with a central connector, said plate has a central cage with vertical lateral wall for housing said connector, radial arms being fixed to the bodies of several shock absorbers spaced apart on said plate and to said wall of the cage for transmitting shock absorbing forces.

Moreover, the PC 7 by means of eight deformable supports (TO) 4 ,. placed along the periphery, mounted on a horizontal plate (GP) 1, in the central hole of which a central case 9 is fixed with a bearing axis. Each TO 4 is made of two racks installed at an angle to each other, the lower of which has a stiffening element 5. When the object falls, the conical caps 3 direct it to the pillow. Moving the pillow, overcoming the effect of shock absorbers 16, which are installed symmetrically on GP 1, causes bending of UP 4 and is regulated by guides 2.

    The tubes 14 with the elements 15 slide along the guides 2 supporting the parallelism of the feeder relative to the GP I. The hydrodynamic braking of the composite cushion is carried out by pushing the floor 6 with the pressure of water passing through the holes of the PC 7. The GP 1 has a peripheral skirt 20 with gas leakage detection and warning, attached to the module and forming an airtight container to trap gas. The initial air cleaning is carried out by the transport cartridge 12 located in the central housing 9 and connected to the central disconnector. 9 h. P . f - ly. 2 Il.

    The invention relates to a protective shield for the shtai head and the functional modules of the underwater station for the purpose of protecting against the fall of objects from the surface or in: during the operation from the bottom or from the surface.
    The aim of the invention is to increase reliability by preventing the occurrence of significant hydrodynamic forces.
    FIG. 1 shows the proposed shield, vertical section; in fig. 2 is the same, top view (upper half) and top view in section (bottom half).
    A horizontal plate 1, approximately rectangular in shape, covering the entire surface of the module, is attached to the top of the connection module (not shown), which has two guide pillars 2 and supporting conical caps 3 that serve as deflectors. eight deformable supports 4, which bend and form a recess directed towards the inner part of the module, while the corner posts mounted on the plate are provided with a stiffening element 5 not rigidly connected to the support supported by it a.

    The supports 4 carry a composite pole, made of a flooring of polypropylene 6, mounted on a perforated sheet 7 or a steel grille, while the restraint 8 ensures the installation of flooring 6 on a sheet 7.
    Plate 1 has a central housing 9 with vertical side posts 10, which is used to install a blocked disconnector, x: a collection that is connected to the cartridge. The pad has also a corresponding hole 11 for the passage of the axial cartridge 12 connected to the disconnector. A cartridge that allows the passage of hydraulic circuits necessary for blocking or opening the disconnector can itself be protected by a deformable deflector cap 13.
    In the section of the passage of the two guide columns 2, the pillow has two holes in which the tubes 14, fixedly attached to the sheet 7 and having the slip segments 15 at their ends, are fixed by welding. At the corners of the shield, four shock absorbers 16 of a hydraulic shock type are installed, the cylinder bodies of which are attached to plate 1, and the upper end sections reach sheet 7. Four radial struts 17 of rigidity

    connect the housing of the shock absorbers 16 with the wall 10 of the housing 9.
    Two mounting shock absorbers 18, fed by compressed fluid from reservoir 19, are mounted on plate 1 and serve to absorb possible shocks at the time of installation of cartridge 12,
    In its lower part, plate 1 is equipped with a skirt 20, which forms an airtight container that serves as a gas trap and which, in the event of a leak, allows this to be detected with the help of appropriate detection devices. An initial purification of trapped air is carried out by a cartridge 12.
    When the object falls, the deflector 3 directs the object in the direction of the pillow
    sinks in spite of braking
    .-
    under the action of shock absorbers 16, causing bending of the supports 4. The pillow movement is regulated by guide columns 2, while the tubes 14 / i slide along the columns and maintain a certain parallelness of the pillow's position relative to the plate 1, respectively, the load is distributed. water through the holes of the perforated sheet 7 causes the ejection of the flooring 8, made of a material less dense than water.
    The fuse boards of the connection modules (FSU), the peripheral monitoring and control modules (CSU) and the main monitoring modules are interchangeable, since they all have
    two identical guide pillars.
    The safety shield for the shaft head has only one central hole for the passage of the central bearing axis, through which the shaft head equipment is immersed by means of a rod string. In addition, its design is similar to the design of the shield described in relation to functional modules.
