Detailed Description
The specific technical solution of the present invention is explained with reference to the drawings.
As shown in fig. 1, the sewage detection sampling device comprises a sampling cylinder 1, wherein the sampling cylinder 1 can be made of transparent pvc material, a sampling outlet is formed in the side wall of the sampling cylinder 1, a valve is arranged at the sampling outlet, and the sampling outlet is used for transferring a water sample in the sampling cylinder 1 into a container after sampling is finished; the top of the sampling cylinder 1 is also provided with a lifting rope 2, and the lifting rope 2 can be provided with a length mark for controlling the depth of the sampling cylinder 1 in the water body; the top of the sampling tube 1 is sealed, the bottom of the sampling tube is provided with a first through hole 8, and an elastic air bag 5 is arranged in the sampling tube 1; the elastic air bag 5 is mutually isolated from the interior of the sampling tube 1, a water pump 4 is arranged in the elastic air bag 5, a water inlet 3 of the water pump 4 is arranged at the top of the sampling tube 1, and the water pump 4 is connected with a rechargeable battery; the water pump 4 is controlled by a remote control system, and the water pump 4 is controlled to drain water or intake water into the elastic air bag 5;
first through-hole 8 on be equipped with first flip 9, first flip 9 one side articulate on the bobbin base inner wall of sampling tube 1.
The top of the sampling tube 1 is provided with a second through hole 6.
And a second flip cover 7 is arranged on the second through hole 6, and one side of the second flip cover 7 is hinged on the outer wall of the top of the sampling tube 1.
During the sample, put into the water with the sampler barrel 1, as shown in fig. 2, open water pump 4, fill water in the elasticity gasbag 5, elasticity gasbag 5 inflation, discharge water and air in the sampler barrel 1, because the expansion of elasticity gasbag 5 volume, withhold first flip 9 on the first through-hole 8 of bottom, seal first through-hole 8, gas and water in the sampler barrel 1 jack-up second flip 7, gas and water are discharged from second through-hole 6. The water and air in the sampling tube 1 are discharged as much as possible. Then under the dead weight of the water in the sampling cylinder 1 and the elastic air bag 5, the water sinks to reach the preset depth, as shown in figure 3, the water pump 4 is started again to discharge the water in the elastic air bag 5 from the water inlet 3, the internal pressure of the sampling cylinder 1 is reduced along with the reduction of the volume of the elastic air bag 5, the second flip cover 7 is propped by the external water pressure to seal the second through hole 6, the first flip cover 9 is propped open towards the sampling cylinder 1 under the external water pressure, the water enters the sampling cylinder 1, and because the water inlet 3 is arranged at the top and the first through hole 8 is arranged at the bottom, the influence of the water discharge of the elastic air bag 5 on the water intake of the sampling cylinder 1 can be ignored. After the water in the elastic air bag 5 is discharged, the water sample in the sampling tube 1 is fed, the water pressure inside and outside the sampling tube 1 is consistent, as shown in fig. 4, the first flip cover 9 falls down under the action of the self weight to seal the first through hole 8, the sampling tube 1 is lifted, and in the process, the second flip cover 7 at the top also seals the second through hole 6 under the water pressure, so that the water cannot enter the sampling tube 1.
