Definitions
- the present invention relates to a barrier gate with overflow, of the type comprising at least one panel tilting flap forming a rectangular shape, articulated by its lower base on the ground so that the panel can move in rotation between a horizontal folded position and a raised position, by through training means including at minus a member articulated by its free end on the side of the panel opposite the ground, said panel comprising stiffening means, in particular in bending see p. ex. CH-A-640 289.
- Dam doors known of this type are designed to withstand the strong pressures of water, in raised position of the valve panel. They for this purpose have reinforcing elements and / or stiffening on their downstream face (opposite to the reservoir).
- This layout has at least two major drawbacks.
- the stiffening elements welded in general on the downstream side entail a high cost of manufacturing and transportation.
- the known doors present in consequently a large thickness, for example of the order 500 mm or more. So in the folded position horizontal, the door already forms in itself a restraint at least this height, very significant, which greatly reduces the difference in useful height of the dam, corresponding to the difference between the levels of water respectively corresponding to the raised positions and folded down from the barrier door.
- the invention proposes to remedy these disadvantages and relates to a barrier gate tilting, thin, while presenting a adequate resistance to water pressure.
- the barrier gate overflow of the type comprising at least one panel tilting flap forming, of articulated rectangular shape by one of the sides on the ground, along a horizontal axis, of so that the panel can rotate in rotation between a horizontal folded position and a position relieved, by means of drive or of traction articulated directly or indirectly on said panel, the latter comprising means for stiffening, especially in bending
- the stiffening means comprise at least one longitudinal element (transverse to the flow of water) and having a relatively high rigidity (in a direction transverse to the panel), said element being hinged either on the panel or on a member connected to said panel, so that a share the forces due to the push of the water and applied to the panel are transmitted to said stiffening element, notably in the substantially upper part of said panel (opposite the ground), and on the other hand, said element of stiffening presents its direction of greater flexural strength, in a direction substantially perpendicular to said panel, at least in the part of the
- the stiffening element is consisting of a flat, longitudinal beam.
- the beam is articulated on the horizontal side of the panel opposite the ground, and the drive means are articulated at their ends free on the upstream part of said stiffening element according to a horizontal axis offset upstream relative to the axis of articulation of the stiffening element on the panel.
- the stiffening element is hinged nearby from the upper part (side opposite to the ground) of the panel.
- the beam stiffening is mounted articulated at the end of a series of connecting rods, the other ends of which are themselves hinged mounted on the upper side of the panel (opposite the ground), said beam resting on the ground in downstream of the panel, the drive means being mounted articulated on said beam.
- the drive means include a cable, tie rod, arm, jack or the like, of which the end opposite to the panel is fixed to means motor, at a height such that, in the raised position of the panel, the stiffening element forms a substantially angle right with said panel.
- the stiffening beam is articulated by a set pins attached to the beam and / or panel, aligned along the same horizontal axis, each associated with a ring fixed on the panel and the beam respectively stiffening.
- supports are provided at the lateral ends of said beam, said supports being attached to the structure of the dam.
- FIG. 1 there is shown so schematic in side view a first form of realization of the device of the invention, forming a dam tilting.
- the structure of the dam itself, the piers and reinforcements, were not represented.
- a hinged door On the ground, forming the base of the dam, and bearing the general reference 1, a hinged door is hinged dam referenced 2, forming a valve.
- Gate 2 articulated on the ground along an axis of articulation A-A, is consisting of at least one sheet metal panel or plate metallic, rectangular in shape and elongated in a direction transverse to the flow of water, symbolized by the arrow f. So, gate 2 is susceptible, in its rotational movement around the axis A-A, to take several positions between a first extreme horizontal position substantially parallel to the ground, and a second raised extreme position where it bears the reference 20, corresponding to a maximum water retention position in the dam upstream of the gate.
- the beam of stiffening consists of a metal plate longitudinal, in the transverse direction to the water flow (arrow f).
- the beam of stiffening 3 has a length (direction transverse to the flow) substantially equivalent or very close to the length in the same direction, the door 2.
- the stiffening beam 3 is mounted articulated on door 2 along a longitudinal axis X-X with respect to the door 2 and beam 3, and transverse to the flow some water. More particularly, the beam is articulated on panel 2 so that the upstream side 4 of the beam 3 is located near the upper side 5 (opposite the floor) of door 2.
- the beam 3 in its position 30, is substantially perpendicular to the plane of door 2.
- Door 2 is likely to be driven in rotation about the horizontal axis A-A by through any known means, such as by example one, and preferably two cables, of which only the cable 6 is visible in FIG. 1.
- two cables are provided, references 6 and 7 (figure 4), of which the free end of each is fixed in rotation, according to an axis Y-Y, on the stiffening beam 3.
- the end of cables 6 and 7 (figure 4) is attached to the upstream end of reinforcements transverse, respectively 8 and 9 provided on the beam 3.
- the reinforcements 8 and 9 are arranged at lateral ends of the stiffening beam 3 (see figure 4). The side reinforcements 8 and 9 protrude by relative to the upstream side 4 of the stiffening beam 3.
- the Y-Y axis of articulation of the cable on the reinforcements side 8 and 9 (and therefore on beam 3) is shifted towards upstream with respect to the axis of articulation X-X of the beam 3 on door 2 (see figures 1 and 4).
- the cable 6 is shown in position 60 in raised position 20 of the door 2, and in respective positions 61 and 62 for the intermediate positions 21 and 22 of door 2.
- Cable 6 goes over a pulley 10 rotatably mounted, for example on a pile the dam (not shown); the end of cable 6 is associated with drive motor means known in themselves but not described further in detail, and symbolized by the functional block 11.
- the double arrow g symbolizes the movement of the cable at the outlet of the means motor 11 to the pulley 10.
- actuation motor means 11 in the direction of cable traction 6 in a direction opposite to the flow of water (arrow f), causes the lifting of door 2, and therefore its rotation around the horizontal axis A-A.
- Door 2 therefore forms an acute angle with the ground.
- the cable pull on the beam also causes the rotation of the beam 3 relative at door 2.
- the beam 3 and door 2 form, in horizontal lowered position of door 2, an angle substantially 180 °; then as the lifting from door 2, the angle becomes less than 180 °.
- the beam 31 In the intermediate position 21, 31 and 61 of the door, beam, cable assembly, the beam 31 has a obtuse angle (between 90 and 180 °) with door 2.
- door 2 continues its rotational movement to reach the raised position 20 where it is substantially vertical or at an angle close to 90 ° with the ground.
- the beam 3 is preferably arranged so that it forms a substantially right angle with door 2.
- beam 3 is intimately associated with door 2, and presents precisely in this transverse direction a very great rigidity. Indeed, the beam 3 being constituted of a planar element, is very little deformable, even undeformable in its plan, that is to say in the direction of the buckling and bending forces to which door 2 is subjected.
- FIG. 2 shows a detailed view schematic on an enlarged scale of the means of secured in rotation of door 2 on the ground 1.
- a rigid metal rod bearing the reference 13 is placed parallel to the ground, close to it, and in a direction transverse to the flow of water, parallel to door 2 and substantially the same length as door 2.
- Rod 13 materializes axis A-A of rotation of the door 2 relative to the ground.
- Rod 13 is maintained relative to the ground through hoops 14 and 15 preferably arranged in pairs, so that the space between each hoop 14-15 of each couple can allow to have a hoop 16 shaped of U inside which the rod 13 is arranged, the arch 16 itself being made integral (by welding for example) from door 2.
- FIG. 3 also shows schematically and on an enlarged scale, a view of detail of the means for rotationally fixing the door 2 relative to beam 3.
- the pin 19 materializes the axis of rotation X-X of beam 3 with respect to door 2. It is planned as much of hoop assemblies 17, 18, trunnion 19 and hoop 25 that necessary along sides 4 and 5 opposite door 2 and beam 3 respectively.
- Figure 4 shows a top view of beam 3 and door 2, in the raised position of door 2, where finds the elements described above, bearing the same references.
- the number and spacing of triplets roll bar 17, 18 and 19 ( Figure 3) is a function of mechanical stresses and general dimensions of the beam and door.
- FIG 5 there is shown a schematic view side of the dam and in particular the structure comprising a pile 26, a buttress 27 resting on the ground 1.
- the cable 6 fixed to the beam 3 itself articulated on door 2.
- a support 28 is provided on the reinforcement 27 of stack 26, and capable of serving as support for beam 3, in the raised position of the door 2, i.e. in position for which the beam 3 is substantially horizontal or slightly oblique. support 28 thus makes it possible to avoid or minimize the effects of vibrations to which beam 3 could be subjected, due to spillage of water in the retaining position (corresponding to the raised position of door 2).
- Figures 6A and 6B show in cross section a variant implementation of the invention, where the elements of the same or similar nature include the same references, with an A index for the raised position of door 2 (figure 6A) and of an index B for the lowered position of door 2 ( Figure 6B).
- a index for the raised position of door 2
- Figure 6B for the lowered position of door 2
- a series of connecting rods 35A (of which only one is shown in FIGS. 6A and 6B).
- the other end of the connecting rod 35A is articulated, along a C-C axis, a beam 36A.
- the C-C axis is horizontal and close to the ground. Note that the axes of articulation A-A, B-B and C-C are materialized by trunnions, rods, cables or the like, so known, and / or as described above and shown in Figures 2 and 3.
- Cable 6A is fixed at its free end (downstream) to beam 36A.
- This has a shape similar to the beam 3 of Figures 1 and 4 and preferably includes a longitudinal rib 37, so that the beam seen in cross section (in a plane parallel to the flow of water) forms a sort of L.
- the beam 36A thus rests on the ground by its upstream part (on the side of the axis joint C-C with the connecting rod 35A) and by the edge lower of rib 37.
- the cable 6A is associated with a return pulley 10, and its other end is connected to means symbolized by a functional block 11. Only the cable 6A is visible in FIGS. 6A and 6B; two cables are provided, at each lateral end of beam 36, similarly to the shape of embodiment shown in Figures 1 to 5.
- downstream of doors 2 is arranged to present a slight slope downstream, from the axis of articulation A-A.
- door 2 is thus allowed to pivot around the axis A-A until taking an extreme position lowered 2B shown in Figure 6B, for which it is substantially horizontal.
- the connecting rod 35B then has a substantially horizontal direction and slightly oblique, parallel to the sloping raft marked 40.
- the beam 36 slides on the downstream raft 40.
- the latter can be fitted out to be fitted with metal rods forming rails, regularly distributed on the raft in a direction parallel to the flow of water.
- metal rods or rails of sliding can also be provided in the form of embodiment shown in Figure 1, thus allowing the downstream end 12 of the beam 3 to slide on these rails.
- the latter have the advantage of allowing to avoid wear and damage to the downstream raft 40.
- downstream ends of cables 6 and 7 can be joined together on the upper side of the door 2 (on the side of the joint B-B of the connecting rods 35).
- Height / length transverse to the flow of water from the door 100 to 300 cm.
- Beam width (in the direction of water flow): 300-500 mm.
- Cables 6 and 7 are capable, as a variant, of pass through the slots provided on door 2, and associated with lips made of flexible material for sealing said slots.
