Definitions

  • My invention relates to locks and more particularly sluice constructions.
  • the water discharge ports are usually provided in the sluice gate, which arrangement, howeverhas the drawback that the energy ofthe Water flow arriving fromV the headwater can strike the vessels in the sluice chamber and can cause a lively surging or turbulent motion of the water inthe sluice chamber subjecting the hawsers to strong jerky strains which can become so great that the hawsers are liable to snap. It is, therefore, not possible in such cases to hold the vessels securely, and besides, the hawser holding devices provided on the banks can stand the strong jerky strain only for a comparatively short time making it necessary to substitute new ones for them.
  • the object of the present invention is to ⁇ obviate such bye-passes by the discharge ports in the sluice gates being so designed that they will reduce very considerably, and in fact, annihilate the energy of iiow of the water flowing through them.
  • This object I attain by providing in front of the inlet aperture as well as close behind the outlet aperture of the discharge ports close to said apertures a guide element for dividing the water now both while entering and leaving the ports into currents of opposite directions, so that the entering currents will impinge upon another and the leaving currents will flow away from one another, in both cases ltransversely with respect to the longitudinal direction of the sluice chamber.
  • the above-mentioned guide-elements are held in proper position by means of rigid members of preferably such a shape as to assist in reducing the energy of ow of the streaming water.
  • the holding members may be formed, for instance, by rods of double-T-irons or the like.
  • the guide-elements themselves may be flat or curved in a manner suited to the particular purpose.
  • Figure 1 is a vertical section through a sluice gate provided with water discharge ports and guide-elements designed according to this invention.
  • Figure 2 is a frontview (head-water side) of a portion of the gate, drawn to a considerably reduced scale while Figure 3 is a horizontal section along the line A-B in Fig. 2, the scale being the same as that of Fig. 1.
  • V Figure 4 is a front-view of one of the guide-elements shown on the left-hand side of Fig. 3.
  • a denotes the sluice gate which is open at its ends and for the sake of diminishing its weight may be and preferably is provided with one or two air-chambers (not shown), at b are shown the discharge ports.
  • c denotes a shutting-off slide provided in each of said ports b and guided between vertical ledges shown at d.
  • a short distance away from the inlet openings and from the outlet discharge openings of the ports b are provided vertical guide elements which may be at plates as shown at f, or curved plates as shown at f'.
  • the two guiding elements near the inlet and outlet opening of one of the ports b may be flat plates, while the guiding elements near the inlet and outlet opening of the other port may be curved, or all the guiding elements may be iiat or all curved plates.
  • the plate on the tail-water side is, preferably, always curved so as to conduct the water towards the adjacent surface of the gate.
  • the flow of the water is indicated by the arrows in Figs. 1 and 3. 'I'he number of the discharge ports and the size of their cross-sectional area depends, of course, Von the individual circumstances of each case and also depends on the shape and sizeV ow of the water entering into', and leaving, the
  • Vand means provided o-n the gate structure for supporting said guide elements in position.
  • sluice gates having passageways transversely extending therethrough, in combination with the outer walls of the gate, curved guideplates disposed a. short distance away from said outer walls in front of the ends of said passageways for transversely'defiecting the flow of water while entering, and emerging from, said passageways, and rigid members projecting from the inner walls of said passageways, holding said guide-plates in position.
  • sluice gates having passageways trans- Versely extending therethrough, in combination with the outer walls of the gate, guide-plates having two curves meeting in a central line and rdisposed a short distance away from said outer walls in front of the outlet of said passageways for transversely deflecting the flow of water while emergingfrom said outlets, and profile irons secured'to the gate structure for holding said guide-plates in position.
