Wherein, the bottom of described small box is higher than the water surface of reservoir water in big casing.Described small box be the cross section being made of metal be the oblique type dead slot of triangle.Described flat faucet is provided with the small sircle hole being prone to simulate Ba Shui.Above the water surface of the reservoir water that described small box is supported in big casing by the runners of four root post structures.Described flat faucet is that to be that the expansion trumpet type of 45 ° of inclined planes is flat cross water-bound to upper surface, is slab construction bottom its water side, and small sircle hole in a row gathers on this flat board.
Test model of the present utility model can be in the lab simulation process of experiment lab simulation dam spillwag chute erosion.By test can draw dam spillwag chute variation characteristic and and injuring relation, can also be by the current in test model, analyze water quality, draw the isoionic content of SO42-, HCO3-, Ca2+, Mg2+ and the data such as pH value, electrical conductivity in seepage proof curtain body, provide the data foundation close to reality for the process and change analyzing the erosion of dam spillwag chute.Macroscopically, the minute surface analysis on spillwag chute can be carried out, analyze the erosion condition on surface.It addition, after erosion a period of time, the storehouse water in big casing can be carried out distillation and be dried, finally draw weight eroded, analyze the composition of weight eroded.
Accompanying drawing explanation
Fig. 1 is device schematic perspective view of the present utility model；
Fig. 2 is device front view of the present utility model；
Fig. 3 is the flat faucet part drawing of device of the present utility model.
The big casing of description of reference numerals: 1-, 2-reservoir water, 3-small box, 4-spillwag chute, 5-runners, 6-water pump, 7-plastic water pipe, the flat faucet of 8-, 9-small sircle hole, the 10-hourglass string bag.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1:
As it is shown in figure 1, this device of the present utility model mainly includes big casing 1, reservoir water 2(needs to illustrate herein: the reservoir water 2 natural storehouse water including various media), small box 3, spillwag chute 4, runners 5, water pump 6, plastic water pipe 7, flat faucet 8, small sircle hole 9 and the hourglass string bag 10.
Can be seen that in conjunction with Fig. 2 (omitting the parts such as plastic water pipe 7, flat faucet 8 and the hourglass string bag 10 in Fig. 2), small box 3 is oblique type dead slot structure that cross section is triangle, small box 3 is supported in big casing 1 by runners 5, small box 3 fills concrete and forms the spillwag chute 4 of simulation, equipped with reservoir water 2 in big casing 1, the water surface of reservoir water 2 is positioned at below the bottom of small box 3, and therefore reservoir water 2 will not submerged overflow face 4.
As it is shown on figure 3, flat faucet 8 is upper surface, to be that the expansion trumpet type of 45 ° of inclined planes is flat cross water-bound, and the front end of its water outlet is positioned at the opening part of trumpet type expansion, and the bottom of water side is slab construction, and small sircle hole 9 in a row gathers on this flat board.The rear end of flat faucet 8 connects plastic water pipe 7, being provided with water pump 6 bottom plastic water pipe 7, water pump 6 is positioned in the hourglass string bag 10, extracts reservoir water 2 by water pump 6, water is flowed through and is come down in torrents to spillwag chute 4 by small sircle hole 9 after plastic water pipe 7 enters flat faucet 8, forms simulation.
Embodiment 1:
As it is shown in figure 1, this device of the present utility model can simulate the whole process that dam spillwag chute suffers erosion.When being embodied as, look for the small box 3 that a metal material is made, be an oblique type dead slot, the concrete of mix is put into wherein, forms spillwag chute 4, entirety is put in big casing 1, supported by four runners 5, adding reservoir water 2 in big casing 1, the water surface is less than small box 3, opens water pump 6, reservoir water 2 in big casing 1 through water pump 6 through plastic water pipe 7, flat faucet 8, flow out finally by small sircle hole 9, flow through spillwag chute 4, circulate with this.Water pump 6 is externally provided with a hourglass string bag 10, and it act as the impurity after preventing physics erosion or the blocking water pump of the sand in water.
