Water quality sampler for collecting water at different water depths
The invention relates to the technical field of water quality samplers, and discloses a water quality sampler for collecting water at different water depths, the water quality sampler comprises an adjusting box, and a support shaft is fixedly connected between the front side and the rear side of the middle part of an inner cavity of the adjusting box. The sampling head is arranged in sampling water, the micro air pump is started, so that high-pressure air is sprayed out of the high-pressure air spraying head to form airflow on the outer side of the sampling head, the sampling head is rotated in the water, and impurities around a sampling point can be blown away by the airflow; then the micro negative pressure pump is started to discharge air in the sampling head to generate negative pressure in the sampling head, so that the sampling water enters the sampling head through the suction pipe and the one-way valve, the sampling head can be prevented from being blocked by a large amount of impurities in the sampling water, and the accuracy of water quality detection is further improved; and the first rack is pulled up and down to drive the second rack to move up and down to adjust the handheld rods with different lengths, so that the sampling depth can be adjusted, water samples can be obtained at different depths, and the water quality detection result is improved.
本发明涉及水质取样器技术领域，公开了一种采集不同水深的水质取样器，包括调节盒，所述调节盒内腔中部的前后两侧之间固定连接有支撑轴。本发明通过将取样头置于取样水的内部，启动微型气泵，从而从高压喷气头内喷出高压气体在取样头的外侧形成气流，在水的内部转动取样头，从而气流能够将取样点周围的杂质吹走，然后启动微型负压泵将取样头内的空气排出使取样头内产生负压，从而取样水通过吸管和单向阀进入取样头内，从而能够避免取样水内有大量杂质和杂质将取样头堵塞，进一步的提高水质检测的准确性，并且上下拉动第一齿条能够带动第二齿条上下移动调节不同长度的手持杆，从而能调节取样深度，能在不同深度获取水样，从而提高水质检测结果。
