Embodiment 1
Simulate the groynes of multi-form and various combination to the model test apparatus of current and influence to sediment effect---multifunction combined groynes model, general structure as shown in Figure 1, this invention mainly is comprised of two main parts: top test section and bottom water-stored section.This device comprises that energy dissipating plate 2, groove with holes 4, clamp bar with holes 5, triangular-notch weir 6, grid 7, arch cross water gallery 8, water pump 11.Energy dissipating plate 2 the place aheads are the ground sill that is installed in the high 13cm in bottom, and 10cm receives the top but the baffle plate of bottom hollow out 3cm behind the ground sill, forms one section interim reservoir 1, can effectively cut down the flow energy of water pump suction, steadily current.
The high 37cm of described test section, long 81cm, two upper lateral part mounting strap hole clamp bars, groove with holes is installed in the bottom, and groove 4 with holes is inserted in groynes sheet bottom, and the upper end is fixed with clamp bar 5 with holes and screw, can adjust according to the test needs size and the angle of groynes sheet, carry out any combination.
Triangular-notch weir 6 is positioned at the afterbody of test section, and the baffle plate that is positioned at triangular-notch weir 6 places can lift adjustment flow out the water yield and test section flow rate of water flow.The water of carrying drogue secretly flows through triangular-notch weir by grid 7, and the drogue of carrying secretly is trapped, and current enter arch by grid 7 and cross water gallery 8, realize system's water body self-loopa.
The course of work of this device: before the test, at first according to the test needs, groynes sheet 3 is installed, is made up adjustment; Secondly, in test section, put into water, connect water pump and corresponding water guide pipeline.Start water pump, partly extract water out from the water storage that is positioned at the bottom, send into the interim reservoir on top.Current are through the energy dissipating plate, and energy reduction enters test section after tending to be steady.Put into an amount of white drogue in the test section end, float floats on waterborne, with water movement, simulates the interaction situation of groynes and current, silt.From the motion of float, can observe streamflow regime, such as whirlpool, backflow, flow path etc., also can reflect washing away, depositing of simulation silt.Finally, current are being carried drogue secretly and are being crossed the diffluence of water gallery through grid 7 to arch, and drogue is trapped on the grid, do not enter arch and cross the water gallery and do not affect current.So far, the bottom water body can be again by water pump suction top, so circulation.
