A handle is arranged at the top end of the motor, hand shanks arearranged on two sides of the motor, antiskid sleeves sleeve the hand shanks, the LED lamps are arranged on the side wall of the motor, the timer is arranged on the motor, the level gauge is arrangedon the motor, the motor is connected with the rotating shaft through a connecting part, the damping spring is arranged in the connecting part, the drilling bit is arranged at the bottom end of the rotating shaft, the water taking heads are arranged on two sides of the bottom end of the rotating shaft, through holes are formed in the water taking heads, the filtering screens are arranged in the water taking heads, the water conveying pipe is arranged in the rotating shaft, one end of the water conveying pipe is connected with the water taking heads, the other end of the water conveying pipe isconnected with the water collection bottle, the air bag is arranged on the water conveying pipe, scales are arranged on the rotating shaft, and the sampling spoon is arranged on the side wall of the bottom end of the drilling bit. The device is convenient in detection, simple in structure and convenient to use, and popularization is facilitated.

Description

technical field [0001] The invention relates to the field of water quality detection, in particular to a safe water quality detection and sampling device. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water (river, river, lake, sea and groundwater) and various industrial drainages. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand etc.; the other category is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. In order ...

AI Technical Summary

Problems solved by technology

With the increasing environmental pollution, water resources are becoming more and more tense. Water resources are an essential part of human life. Therefore, more and more attention has been paid to the control of water pollution recently. Water quality testing. Due to the complexity of the monitored area and geological environment, water quality testing is time-consuming, labor-intensive, and low-efficiency. It cannot meet a wide range and it is difficult to extract samples.
