Definitions

  • the present invention relates to an overflow dam with a tilting panel.
  • a tilting panel comprising at least one panel serving as a valve, articulated at its base on the ground along a horizontal axis transverse to the flow, between two extreme positions, one raised opposing the flow, the other folded down substantially horizontal, by means rotary drive comprising at least one articulated link by a first end on the panel around a horizontal axis transverse to the flow, and the second end of which is capable of being move in contact with the ground in the axis of the flow, by through translation means comprising at least one cable able to drive the second end of the link by means traction.
  • this element stiffens the tilting panel and, folded down, the assembly offers only a slight opposition to the flow since the stiffener, by pivoting, is placed downstream in the axis of the panel.
  • the difference in useful height at the dam i.e. the difference in water level between the raised and lowered positions of the panel.
  • these stiffening elements cause technical complications and additional costs and in addition, the lifting such a panel requires either the use of cylinders, which are expensive to install and use, i.e. at least two cables per panel.
  • the invention proposes to remedy these drawbacks by having for object a tilting overflow dam using at least one thin panel, activated by a simple lifting system, inexpensive, easy to install and maintain. Furthermore, in the case of several panels, the system is able to actuate them from a single cable to modulate the flow easily and in one single operation, without having to handle each panel individually.
  • the device of the invention is capable of being quickly adapted to existing dams without incurring significant costs.
  • the overflow dam with tilting panel comprising at least one panel forming a valve, articulated on the ground by its following base a horizontal axis transverse to the flow, between two positions extremes, one raised substantially vertical, the other folded substantially horizontal, by means of rotational drive comprising at least one link fixed by a first end to the panel around a horizontal axis transverse to the flow, and the second of which end is able to move in contact on the ground in the axis of the flow by means of translation means, comprising at less a cable able to drive the second end of the link thanks to traction means, is characterized in that said means of traction include at least one return member secured to the second end of the link.
  • this return member gives the cable a U shape or of V, the two strands of which are located upstream of said member in a general direction substantially parallel to the flow.
  • the link is arranged downstream of the panel.
  • the return member comprises at least one pulley linked to the second end of the link.
  • the tilting panel dam comprises at least one second deflection member, fixed and capable of deflecting the two strands of the cable.
  • the second fixed member is composed of two elements located between the base of the panel and the end of the rod which rests at floor when the panel is in the raised position, and these two elements are able to deflect the two strands of the cable perpendicular to the flow.
  • At least one end of the cable is associated with traction means.
  • Another possibility of realization consists in aligning several panels capable of being actuated by a single cable, in order to achieve in one single operation the successive lifting of said panels.
  • two rods are associated with each panel in order to to provide better rigidity.
  • the two rods delimit, with the free edge of the panel, a triangle or a trapeze.
  • FIG. 1 is shown in cross section a first embodiment of the invention forming a panel dam tilting.
  • a panel 2 On the ground 1, having a slope of approximately 10 to 15 ° and forming the raft of the dam, is hinged a panel 2 forming a gate of the dam.
  • This panel made of metallic material, has a rectangular shape and elongated in the vertical direction and very thin compared to to its other dimensions. It is movable in rotation around a horizontal axis X-X ', on the ground, transverse to the flow symbolized by the arrow f. This articulation on the ground is achieved by all means of securing known, not shown, such as a metal rod materializing the axis X-X 'and U-shaped arches fixed on the panel 2.
  • the strike off has a slope of approximately 10 to 15 °.
  • Panel 2 can take a multitude of positions between two positions extremes, one raised, substantially vertical, opposing the flow water, as shown in Figure 1, and a second completely folded down, substantially horizontal, allowing the water to flow freely.
  • the slope made in the raft accommodates the panel 2 in folded position which therefore does not have any projection which would slow the flow some water.
  • the panel 2 made with the ground 1 at an angle between 60 ° and 80 °, preferably close to 70 °.
  • the panel 2 On the panel 2 is articulated at least one connecting rod carrying the reference 3 and generally elongated. It is rotated on panel 2 around an axis YY ', parallel to the axis of rotation X-X' of panel 2, located approximately two thirds of the latter in relation to the ground and in the middle in the direction parallel to the axis XX '.
  • the articulation around the axis YY ', not shown, uses all known means.
  • Two other pulleys 5 and 6 (of which only pulley 5 is visible in the figure 1), called return pulleys, are fixed to the downstream raft, on either side of the rod 3 seen from above, and substantially perpendicular to the axis YY ' when the panel 2 is in the raised position. So the return pulleys 5 and 6 form with the movable pulley 4 and for each position of this last, an equilateral triangle.
  • a cable 7 passes through the return pulleys 5 and 6 and into the movable pulley 4 so that at least one of its ends, and preferably the two, are connected on a bank to known traction motor means (not shown).
  • a block bearing the reference 8, and whose role will be specified later, is fixed to the face of the panel located downstream, substantially at middle in the direction of the axis X-X ', and under the axis YY'.
  • Figure 2 a schematic top view of a variant where several panels 2, 2 'are associated in series and 2 "as described in FIG. 1 but in the folded position.
  • Each 2, 2 'and 2 "panel is associated with a link respectively 3, 3 'and 3 "and the corresponding movable pulleys 4, 4' and 4" secured to the links.
  • two fixed return pulleys are associated with each panel, referenced 5 and 6 for the panel 2, 5 'and 6' for the panel 2 ', and finally 5 “and 6" for the 2 "panel.
  • Each pair of fixed pulleys (5, 6), (5 ', 6') and (5 ", 6" is protected from waterborne debris by a parallelepiped housing (not shown) fixed to the downstream raft. Seen face when flowing, this case has a general shape of an inverted U and the front panel is open.
  • the long side of the parallelepiped is parallel to the axis XX 'and is located between the latter and the fixed pulleys.
  • the side parts of the housing are parallel to the flow and have recesses to let the cable pass 7.
  • the different panels are aligned along the axis X-X 'which is common to them and are contiguous, so as to form a watertight door in position noted.
  • a traction motor means such as winch 9 and 9 'respectively, connected by cable 7 which passes through each of the fixed and mobile pulleys.
  • only one winch can be used and the other end of cable 7 is then attached to the other bank.
  • these strands parallel to the flow limits the risks of lateral tilting of the 3, 3 'and 3 "links during their ascent.
  • the friction inherent in the system induces displacements of the 3, 3 'and 3 "rods offset in time and therefore progressive lifting of each panel 2, 2 'and 2 ".
  • the first panel 2 can be completely raised when the second panel 2 'is at 80% of its raised position and the third, 3 ", at 50 or 60% raised.
  • the wedge 8a while resting on the ground, prevents the panel 2a from pressing on return pulleys 5 and 6 of which only pulley 5 is visible on all of Figures 3A, 3B and 3C.
  • the wedge 8a is suitable for transmit to the raft 1 the force of the water exerted on the panel 2a. Then, as mentioned above, blocking one of the means of traction and act on the second causes the tension of the cable 7 which creates a force on the pulley 4 via the return pulleys 5 and 6. This force, parallel to the flow and in the opposite direction, displaces the pulley 4 which pulls on the link 3 of which it is integral.
  • these means of sliding include on the rod a roller or a coating with low coefficient of friction, cooperating with a fixed metal plate on the downstream raft.
  • the raft does not deteriorate when traveling of the link 3.
  • the rod 3 then begins to rise to reach the intermediate position 3b of FIG. 3B, and by pushing acts on the panel 2 which pivots along the axis XX 'and lifts (position 2b).
  • the panel rotations 2 along the axis X-X 'and the rod 3 along the axis Y-Y' are done in opposite senses.
  • the link 3 continues to run on the write off 1 until reaching the raised position 3c, visible in FIG. 3C. In this position, the panel 2c opposes the flow f of the water.
  • a stop (not shown) is capable of holding the link 3 in its position raised 3c, transmitting to the raft the efforts of the water retention on panel 2.
  • This retractable stop fixed for example on the plate metallic (not shown) associated with the raft, does not interfere with the ascent of the rod 3 and is capable of projecting with this same plate immediately after the passage of the rod 3 preventing it from coming back down.
  • This stop may consist for example of a flat iron articulated on the ground around an axis Z-Z 'parallel to X-X' and Y-Y ', downstream of Y-Y'. This iron flat, transverse to the flow and as long as the dam, is actuated by known lifting means such as a jack for example.
  • the stop is thus able to have a raised position where it retains the end of each link such as the link 3 and a horizontal position, placed on the raft, leaving the rod 3 and the panel 2 to descend.
  • a hook (not shown) is provided at the horizontal free edge opposite the axis X-X 'of panel 2 in order to maneuver it using any means known, mechanical or manual.
  • FIG. 4 Another possible embodiment is shown in FIG. 4.
  • the device top view schematically in the folded position, includes two rods 3 and 3 'associated in pairs with a single panel 2. This arrangement gives excellent rigidity to the assembly, in particular in raised position of panel 2.
  • the two links 3 and 3 ' are arranged in a V (case of Figure 4) or trapezoid with respect to panel 2.
  • the effort of thrust of the rods is thus better distributed on the panel 2 in phase lifting.
  • the force exerted on the latter by the water retention is collected by two elements, instead of only one in the configuration in Figure 2, ensuring better overall stability.
