Embodiment
With reference to accompanying drawing, this device is provided with sampling cabinet 1, is provided with sampling jar 2 and water diversion disk in the sampling cabinet 1, and water diversion disk is utilized hollow central siphon 5 to form with lower wall 4 to be in the same place by the dish 3 of going up of equal diameters.Lower wall 4 is fixing, along the periphery in the lower wall 4 a plurality of lower walls hole 6 is set, and the quantity in lower wall hole 6 is identical with the water intaking number of times that needs, and lower wall hole 6 is connected through flexible pipe 7 with sampling jar 2, and is corresponding one by one.Last dish 3 is provided with one and goes up dish hole 8, on coil hole 8 and the corresponding setting in the position in lower wall hole 6.Last dish hole 8 is connected with water pump 12 through connection hard tube 9, rotary faucet 10, hollow central siphon 5, upper hose 11.The periphery of last dish 3 is provided with dish tooth 13, and dish tooth 13 is meshed with the driven wheel 15 of stepper motor 14, under the drive of stepper motor 14, on coil 3 and can rotate around hollow central siphon 5.Said lower wall 4 is installed together through hollow central siphon 5 with last dish 3 with one heart, and through nut 16 and bearing 17 dish 3 and lower wall 4 is closely linked, and realizes the water shutoff purpose.Said lower wall 4 is arranged on the support 18.Stepper motor 14 is fixed on the fixed head 19.Said lower wall hole 6 can evenly be provided with 24 at the periphery in the lower wall 4, realizes at a distance from sampling in a hour once.Water pump 12 is placed on the position that requires sampling.Pipeline and cable are connected on the sampling cabinet 1.Drive through microcomputer controller control step motor 14 and to go up dish 3 rotations, on coil 3 the lower wall hole of going up dish hole 8 and lower wall 46 relatively the time, start water pump 12, water gets into sampling jar 2.Through after the time that requires, on coil 3 rotation and lower wall hole 6 start water pump 12 samplings relatively the time again.Go round and begin again the water sample in the moment that can obtain requiring.Set time is fetched water sample, the replacing sampling jar gets final product.Owing to be to work in the open air, the net electricity is inconvenient, and desired power is less, adopts wind light mutual complementing power generation equipment to add accumulator as kinetic energy.
The course of work of the present invention is following:
