Definitions

  • the present invention relates to marine barrage installations and, in particular, to installations used for temporarily blocking the communicating channels between a lagoon and the open sea whenever the water level in the lagoon tends to rise above a maximum acceptable limit.
  • Italian Patent No. 906 937 by the same Applicant describes and illustrates an installation with sluice gates which can be lowered to protect a lagoon from the open sea, in which each sluice gate is hollow and is articulated to the sea bed about a horizontal axis, and can be pivoted about its articulation axis simply by making use of its buoyancy which is adjusted by varying the quantity of water filling the internal cavity of the sluice gate. This is achieved by admitting air to or expelling air from the sluice gate so as to empty it or fill it with water respectively.
  • the sluice gate In its fully lowered position, the sluice gate is housed in a recess formed in the sea bed so as not to project above the profile thereof (the depth of the communicating channel between a lagoon and the open sea may be quite small).
  • the sluice gate When the sluice gate is in a raised position corresponding to the presence of a certain volume of air within it, however, it is free, as can be inferred from the text of the aforementioned patent, to oscillate as a result of the variable thrust exerted on it by the sea and, at any time, to find the equilibrium position in which the various forces to which it is subject balance each other.
  • this solution minimises the mechanical stresses to which the hinges used for its articulation to the sea bed are subject during the operation of the sluice gate.
  • each hinge must have a releasable coupling for fixing it to the bed.
  • This coupling must enable the coupling and release operations to be carried out easily and at the same time must provide the necessary precision of mounting.
  • the coupling must enable the quick connection of compressed air, hydraulic and/or electrical supplies to the systems on the sluice gate and of any mechanical transmission used for detecting the angle of pivoting of the sluice gate at any time.
  • the object of the present invention is to improve the hinge device described in the Italian Patent Application No. 20666-A/87 cited above by improving its precision and reliability.
  • the subject of the invention is a hinge device comprising: - a first hinge element connected to the sluice gate, - a second hinge element articulated to the first hinge element and connected to a releasable coupling for fixing it to the bed, in which the releasable coupling comprises: - a conical female element anchored to a fixed base located on the bed, - a male element which can be coupled to the female element and connected to the second element of the hinge, and - a tie-rod which can be coupled to the male element from below when the latter is in its coupled position in the female element and can be pulled downwardly in order to lock the coupling in its coupled condition, the hinge device being characterised in that:
  • FIGs 1 and 2 of the appended drawings show three sluice gates 1 forming part of an installation of the type described in the introduction of the present description, in the raised position and in the lowered position respectively.
  • each sluice gate 1 is articulated by means of at least two hinge devices 2 to a fixed concrete base 3 sunk into the sea bed 4 and defining a recess 5 which houses the sluice gates 1 in the lowered position so that the sluice gates do not project above the profile of the bottom in that position (Fig. 2).
  • the base 3 includes a gallery 6 which is hermetically isolated from the sea bed for persons employed in the control and maintenance of the installation. The gallery 6 provides access to the control and connection equipment (described in detail below) associated with the hinge devices 2.
  • each sluice gate 1 has a hollow sheet-steel structure which can be filled to a greater or lesser extent with water (the holes for the passage of the water are not visible in the drawings) by the control of the quantity of air admitted to its interior through pipes 7 connected to the two hinge devices 2.
  • each hinge device 2 includes a first hinge element 8 constituted by a plate welded to the structure of the sluice gate 1 and provided with bracing 9.
  • the second hinge element, indicated 10, is fork-shaped and is articulated to the element 8 by means of a pin 11 (Fig. 6).
  • the hinge unit is connected releasably to the base 3 by means of a male-and-female coupling 12.
  • the coupling 12 comprises an upwardly-divergent, conical female element 13 anchored to the base 3 and a male element 14 which can be coupled to the element 13 and is fixed to the second hinge element 10.
  • the male element is constituted by two superposed and spaced-apart plates 15, 16 connected by an axial tube 17 which is eccentric with respect to the axis of the cone 13 (with reference to the coupled condition of the coupling) and by means of radial flanges 18. The eccentric position of the tube 17 leaves the necessary space within the cone 13 for electrical, hydraulic and mechanical connection means which will be described in detail below.
  • the eccentric positioning of the tube 17 is only necessary in embodiments which involve a large number of connections and a system of small bulk.
  • the lower plate 16 (Fig. 6) has a convex circumferential edge provided, as is the plate 15, with a sealing ring for a perfect fit in a cylindrical end part of the female element 13.
  • the lower end of the cylindrical part 19 has a welded flange to which a horizontal plate 20 is fixed by screws.
  • a tube 21 with radial flanges 22 projects below the plate 20 and communicates with the space inside the cone 13.
  • the spaces within the cone 13 and the cylinder 21 communicate with pipes 23 for the intake of water as provided for in the prior patent application No. 20666-A/87.
  • a shut-off valve 24 is associated with each pipe 23 and is kept closed as long as the element 14 is not housed in the cone.
  • the lower end of the tube 21 supports the upper end of the body of a fluid cylinder 25.
  • the piston 26 of the cylinder 25 is fixed to a tubular rod 27 constituting a tie-rod which can be used to lock the element 14 in the cone 13.
  • the internal duct of the tie-rod 27 communicates with the space inside the cone 13 and a shut-off valve 28 associated therewith is kept closed as long as the element 14 is not housed in the element 13.
  • the internal duct of the tie-rod 27 communicates with the respective air-supply pipe 7 (Fig. 3) through a duct 29 formed in the element 10 (Fig. 6), a box 30 fixed to the outside of the element 10, a rotary joint 31 and an elbow pipe 32 (see also Fig. 7).
  • the upper end of the tie-rod 27 is provided with radial appendages 33 which cooperate with a seat 34 in the plate 20 in the manner of a bayonet coupling.
  • the tie-rod 27 can be raised by means of the cylinder 25 and made to pass through the seat 34.
  • the element 14 can then be pulled into or locked within the cone 13 by the rotation and subsequent lowering of the tie-rod.
  • the rotation of the tie-rod 27 necessary to engage it with the seat 34 is achieved by an auxiliary cylinder 35 carried by a horizontal plate 36 fixed to the body of the cylinder 25.
  • the cylinder 35 has a piston 36 engaged with a nib 37 which projects radially from a plate 38 fixed to the tie-rod 27.
  • Each sluice gate 1 has on-board auxiliary equipment requiring an electrical supply (indicator light, pump for accelerating the fitting of the sluice gate, etc.). Some of this equipment (for example the pumps) may require a lubrication circuit. Moreover, any rotatable mechanical shaft on the side of the base must be connected to the sluice gate by means of a transmission to enable the capture of data relating to the angle of pivoting of the sluice gate at any time. In short, the coupling 12 must be provided with releasable electrical, hydraulic and mechanical connection means. For this purpose, three cylindrical guide pillars 39 extend between the plates 20 and 36 (see Figs. 4, 6, 8) and a horizontal plate 40 is mounted for sliding thereon (by means of a bush 41 and rollers 42 - Fig. 8). The plate 40 is moved vertically by a jack 43 fixed to the plate 36.
  • the releasable connection means comprise a first set of vertical terminal rods (four rods 44a for the electrical lines, one rod 45a for the mechanical connection) projecting downwardly from the male element 14 of the coupling 12 (see also Figures 10, 11, 12) and a second set of vertical terminal rods 44b, 45b, 46b anchored in seats 47 in the plate 40 and projecting upwardly.
  • the free ends of the two sets of rods are provided with quick coupling means.
  • these means are of any known type and have therefore not been shown in detail in the appended drawings.
  • the terminal rods 44a, 45a, 46a are fixed to the plate 15 of the element 14 and have free ends which partially engage bushes 48 carried by the plate 16.
  • the upper ends of the rods 44b, 45b and 46b are guided in tubular appendages 49 projecting below the plate 20 and each provided with a shut-off valve 50 (with a control lever 51) which is kept closed as long as the element 14 is not housed in the cone 13.
  • the terminal rods 44b, 45b, 46b are also provided with means for their micrometric axial displacement in order to effect the final travel for coupling with the upper rods. More specifically, each lower rod has a rotatable ring nut 52 (fixed axially) which is screwed onto an end part of the respective appendage 49 to effect the final travel.
  • the two rods 46a, 46b have internal rotatable shafts 53 with coupling ends 53a, 53b having the shapes shown in Figure 14.
  • the electrical lines and the hydraulic conduits are connected to a first manifold 54 which is connected by means of flexible tubes to a second manifold 55 carried by the sluice gate (Fig. 5).
  • the shafts 53 are connected to a gearbox 56 (Fig. 12) whose output shaft is on the axis of the pin and is connected to an element fixed to the sluice gate by means of a lever 57.
  • the male element is constituted by two superposed and spaced-apart plates 15, 16 connected by an axial tube 17 which, unlike the embodiment shown in Figure 6, is coaxial with the cone 13 (with reference to the coupled condition of the coupling).
  • the two plates 15, 16 are joined by a plurality of radial flanges 18.
  • the lower plate 16 has a convex circumferential edge for a perfect fit in the cylindrical end part 19 of the female element 13.
  • the lower end of the cylindrical part 19 has a welded flange to which a horizontal plate 20 is fixed by screws.
  • a tube 21 projects below the plate 20 and has radial flanges 22 which communicate with the space inside the cone 13.
  • the spaces within the cone 13 and the cylinder 21 communicate with pipes 183 which are used both for the admission of air to the sluice gate through valves 188 connected to a compressor (not shown) and for withdrawing air, together with any water present in the sluice gate, through valves 184 connected to a suction pump (not shown).
  • a shut-off valve 24 is associated with each pipe 23 and is kept closed as long as the element 14 is not housed in the cone 13.
  • the lower end of the tube 21 supports the upper end of the cone of a fluid cylinder 25.
  • the piston 26 of the cylinder 25 is fixed to a rod 27 constituting a tie-rod which can be used to lock the element 14 in the cone 13.
  • the upper end of the tie-rod 27 is provided with radial appendages 33 which cooperate with a respective seat 34 in the plate 20 in the manner of a bayonet coupling.
  • the tie-rod 27 can be raised by means of the cylinder 25 and made to pass through the seat 34.
  • the element 14 can then be pulled into or locked within the cone 13 by the rotation and subsequent lowering of the tie-rod.
  • auxiliary cylinder 35 carried by a horizontal plate 36 fixed to the body of the cylinder 25.
  • the cylinder 35 has a piston engaged with a nib 37 which projects radially from a plate fixed to the tie-rod 27.
  • the tie-rod 27 has a threaded lower end 27a which can be engaged by a nut 27b which bears against the lower end of the cylinder.
  • the tie-rod 27 can thus be locked in its lowered position, enabling the pressure in the chamber of the cylinder to be released.
  • the tie-rod 27 is not hollow and is not used for the supply of air.
  • the male element on the other hand, has two axial air ducts 29a which communicate with the interior of the sluice gate through ducts 29 formed in the element 10 of the hinge, ducts 29c formed in two boxes 30 associated with two opposite faces of the element 10, respective rotary joints 31, and elbow pipes 32 which communicate at one end with the ducts 29c through the rotary joints and at the other end with the internal cavity of the sluice gate.
  • the lower ends of the ducts 29a communicate with two holes 29b formed in the lower plate 16 of the male element 14.
  • Two rubber bushes 80 are mounted beneath the plate 16 coaxially with the holes 29b (see Figure 6) and each is reinforced with a steel spiral 80a which is sealingly housed in a respective hole 29d formed in the plate 20.
  • Stainless-steel rings 80b are welded in correspondence with the walls of the holes 29d and house the bushes 80.
  • the holes 29d communicate with the ducts 18.
  • the seal between the plate 15 and the cone 13 is ensured by a flat sealing ring 15b which has a cross-section like the symbol for a musical note and is fitted in a recessed annular region of the plate 15.
  • the peripheral wall of the plate is also provided with a stainless-steel sheathing ring 15a.
  • the plate 15 is provided with a radial pin 100 which is intended to engage a recess 101 in the cone 13 (see also Figure 3).
  • the coupling of the hinge to the sea bed must also effect the electrical connection of sensor devices which are mounted on the sluice gate, as well as a mechanical connection which serves to detect the angle of pivoting of the sluice gate at any time.
  • a bush 48 is associated with the plate 16 and a terminal 120 mounted therein is connected electrically by means of a line 121 to a further terminal contact 122 intended to be connected to the devices on board the sluice gate by means of a further flexible connecting line (not shown).
  • the terminal contact 120 is adapted to engage a further rod-shaped contact element 123 housed slidably in the bush 48.
  • the contact rod 123 is carried by a sleeve 124 which can be screwed manually, like a ring nut, onto an end part 125 of the body of a valve 126 associated with a vertical tubular duct 127 which passes through the plate 20.
  • the valve 126 serves to discharge the water between the plate 16 and the plate 20 during the coupling operation.
  • the plate 16 is provided with a further bush 48 in which a first coupling element 53a connected by a Cardan shaft 128 to the input shaft 129 of a gearbox 56 associated with the upper plate 15 of the male element is mounted rotatably by means of bearings.
  • the box 56 contains a pair of bevel gears connecting the shaft 129, which has a vertical axis, to a horizontal shaft 130 one end of which projects from the box 56 and has a gear 131 keyed thereto.
  • This gear meshes with a larger-diameter gear 132 which is connected to the sluice gate by a shaft 133 (shown only schematically in broken outline).
  • the pivoting of the sluice gate about the hinge therefore causes a rotation of the gear 132 which is transmitted to the coupling element 53a by means of the gear 131, the box 56 and the shafts 129, 128.
  • the element 53a is adapted to be coupled for rotation, in the same way as that shown in Figure 14, to a further coupling element 53b carried by a shaft 53 and mounted rotatably in a tubular rod 46b by means of bearings.
  • the rod can be inserted through the body 134 of a shut-off valve which is fixed beneath the plate 20 and communicates with a through-hole 135 in the plate.
  • the valve 134 is used to eliminate the water retained between the plate 20 and the plate 16 during the coupling stage, after which the tubular rod 46b can be inserted through the valve 134 of the hole 135 until it causes the engagement of the coupling elements 53a, 53b.
  • This operation can be carried out manually, the means being locked by the screwing of a ring nut 136 onto the body of the valve.
  • the lower end of the tubular rod 46b carries a measuring device (for example an encoder) for detecting the angle of pivoting of the sluice gate which is transmitted by the mechanical transmission described above to the sensor device 137 by means of the shaft 53.
  • the mechanical and electrical coupling operation may be effected automatically with the use of a vertically movable plate as shown in Figure 6.
  • Figure 21 shows a variant of Figure 15, in which the connection for the air-supply between the male element and the sluice gate is effected by means of flexible tubes 150.
  • Figures 22, 23 and 24 show views which correspond to those of Figures 15, 16 and 18 and relate to an embodiment in which the axes of the bushes 48 for the electrical and mechanical service connections lie in a plane containing the central axis of the cone 13, whilst the axes of the air-holes 29b are spaced from that plane.
  • the two boxes 30 may, in an alternative embodiment, be connected to flexible tubes, as in Figure 21.
