Description
Technical field
A kind of hydrology adjustable-height of the utility model sediment sampling device, relate to the sediment sampling device used in a kind of hydrologic survey, belong to field of environment protection equipment, evacuated collection differing heights water sample can be utilized in particular to one, and the device that thief hatch is subject to the silt sample of water hammering effects can be reduced.
Background technology
Water body suspended sediment characteristic, not only comprises the quantative attribute of silt, and comprises grain size characteristic and the chemical feature of silt.The grain size characteristic of silt, it is the important factor determining River Sediment Carrying Capacity, the change of sediment size feature will cause the change of middle and lower reaches alluvial channel alluvial state, and meanwhile, the chemical substance of moving with silt such as nutritive salt and pollutant will cause the change of middle and lower reaches water quality.Carry out the sampling research of water body suspended sediment, not only may be used for the source differentiating silt and chemical contamination, be also analyze downstream river course erosion and deposition to amass and the important means of water pollution simultaneously.The sampling research of current suspended sediment, the main horizontal type sampling thief that adopts is sampled.Horizontal type sampling thief is made up of thin-wall steel tube, and volume 0.5 ~ 2.0 liter, there is lid at two ends, and Gai Yuan is equipped with tension spring.During sampling, open cover, current flow through from cylinder, then master cock, are closed by cover by means of spring tension, gather water sample.The shortcoming of this instrument is: need a dead lift instrument during sampling, waste of manpower, and sampling amount is little, do not possess representativeness, sediments sample under water can only be got simultaneously, be difficult to obtain deep layer sample, sample is difficult to accurate location under water, repeatedly stratified sampling reaches the object gathering different depth silt sample and cannot realize, and serious by silt pulsations affect, the representativeness of single-point sampling achievement is poor.
Summary of the invention
In order to solve the problem, a kind of hydrology adjustable-height of the utility model sediment sampling device provides one and can utilize evacuated collection differing heights water sample, and can reduce the device that thief hatch is subject to the silt sample of water hammering effects.Structure is simple, easy to use, effectively can improve the efficiency of sampling operation.
A kind of hydrology adjustable-height of the utility model sediment sampling device is achieved in that a kind of hydrology adjustable-height of the utility model sediment sampling device is made up of regulating device and water storage device.Regulating device is by bracing frame, the sampling mouth of pipe, gravitation ball, sampling pipe, be rotatably connected frame, scale label, pointer, flexible pipe and drum composition, drum is placed on bracing frame, pointer is placed in drum side, five sampling pipe one end are uniformly distributed to be placed in and are rotatably connected on frame, the sampling mouth of pipe is placed in the sampling pipe other end, five gravitation balls respectively correspondence are placed on the sampling pipe other end, flexible pipe one end is placed in and is rotatably connected on frame, the other end curls on drum, scale label is placed on flexible pipe, water storage device is by exhaust tube, vacuum pump, abutment ring, reserve tank, liquid reserve tank, filter screen, sampling cabinet, diaphragm seal, water pipe and sealing-plug composition, bracing frame is placed in liquid reserve tank side, reserve tank and sampling cabinet are placed in liquid reserve tank respectively, filter screen is equipped with between reserve tank and sampling cabinet, diaphragm seal is placed on filter screen, the flexible pipe other end is connected with water pipe one end, the water pipe other end is deep in sampling cabinet through the diaphragm seal on liquid reserve tank and the diaphragm seal on filter screen successively.Vacuum pump is placed on liquid reserve tank, and is connected with exhaust tube, and the exhaust tube other end is connected with the reserve tank in liquid reserve tank by sealing-plug.
During use, when needs carry out silt collection time, only need the frame that be rotatably connected be positioned in water, by the scale on flexible pipe, observe the height of flexible pipe in water, the sampling of differing heights water can be carried out as required, the described collection tube be rotatably connected on frame, when running into current and being larger, can rotate around the frame that is rotatably connected, effectively can reduce the impact that thief hatch is subject to water impact, then vacuum pump is opened, exhaust tube constantly extracts the air of liquid reserve tank inside, the pressure of liquid reserve tank inside is made to be less than outside pressure, water can under the effect of outside pressure, water passes through flexible pipe successively, water pipe enters in the sampling cabinet of liquid reserve tank bottom, silt impermeable filter screen and be present in sampling cabinet, water then can be pressed in the reserve tank of top, thus carry out silt initial gross separation, reach and can gather differing heights, reduce the object that thief hatch is subject to the sediment load sampling of water hammering effects.
Beneficial effect
One, the efficiency of sampling operation can effectively be improved
Two, structure is simple, easy to use.
Three, with low cost, be easy to promote.
