Description

Technical Field

[0001] The invention relates to the field of river water clarity detection, and in particular to a water sample collection device based on river water clarity detection. Background Art

[0002] Water sampling equipment has many advantages, which make it play an important role in water quality monitoring and environmental management. Traditional water quality sampling methods usually require manual operation, which is time-consuming and laborious. The portable water quality automatic sampler can automatically complete the sampling process, greatly improving the sampling efficiency and reducing labor costs. Some water quality samplers can realize the three-in-one functions of water collection, pretreatment and water supply, which makes them more flexible and efficient in practical applications. The fully automatic water quality sampler has an automatic circulation sampling function. Through the built-in intelligent control system, the water sample can be automatically circulated inside the sampler, which not only reduces the frequency and intensity of manual operation, but also improves the monitoring efficiency. The intelligent water sampling equipment of drones can realize remote beyond-line-of-sight water sampling in the process of handling sudden environmental events, quickly respond to emergencies, and improve the emergency practical level and joint prevention and control capabilities of the ecological environment department. The portable water quality automatic sampler supports a variety of sampling methods and modes, which can meet the needs of different monitoring scenarios and provide more comprehensive and accurate water quality data support. These advantages make water sampling equipment increasingly important in modern water quality monitoring and environmental protection.

[0013] The present invention provides a water sample collection device based on river water clarity detection. It has the following beneficial effects: 1) The water sampling equipment based on river water clarity detection is provided with a telescopic sampling device. When in use, a suitable location is selected for water sampling. When collecting water samples, the staff first adjusts the distance between the sampling bottle and the floating plate. When adjusting the distance, reasonable adjustments are made according to the depth at which the staff needs to collect water samples. When adjusting, the staff first fixes one end of the rope on the first hanging ring, and the rope passes through the floating plate, the fixed plate and the limit mechanism in turn, and then passes the rope through the second hanging ring, passes through the appropriate length, and adjusts the maximum distance between the sampling bottle and the floating plate at the same time. After adjustment, the rope is directly tied to the second hanging ring, and the sampling depth of the sampling bottle is changed by changing the distance at which the rope is tied to the second hanging ring. 2) The water sampling equipment based on river water quality detection can also adjust the sampling depth of the sampling bottle by setting a limit mechanism.

When clamping, the bolt and the nut are directly tightened. At this time, the clamp clamps the rope. The two clamps are located above the limit plate and will not fall off. Therefore, the length of the rope is limited. At this time, the sampling depth of the sampling bottle is also limited. When sampling, other ropes can be used to fix the second lifting ring. After fixing it on the second lifting ring, the user directly pulls it on the shore. When sampling, the operator opens the solenoid valve through an external switch, and water can be taken at this time; 3) The water sample collection equipment based on river water clarity detection is provided with a heating device. After water is taken, the water sample enters the water collecting box through the liquid inlet pipe and is injected into the sampling tube through the water injection pipe. Under the action of the spring and the slider, the sampling tube remains stable to prevent leakage. At the same time, the water temperature is detected and compared with the temperature in the collection box through the display screen. If the temperature in the collection box is higher than the outside, the heating wire in the heating device is started, and the heating wire heats the air and blows it to the top of the heating box through the heating fan. Then, the hot air is discharged into the collection box through the exhaust pipe to achieve the purpose of heating; if the temperature in the collection box is higher than the outside, the cooling fan is started to cool the inside of the collection box.

[0014] 4) The water sample collection equipment based on river water purity detection sets up a water sample detection device. The staff places six sampling tubes containing water samples on the test tube rack, starts the cylinder to drive the fixed frame at the bottom of the piston rod to descend, so that the stirring rod and the stirring plate are extended into the sampling tube, and then the rotating motor is started to drive the driving wheel on the main shaft to rotate, and the driven wheel is driven by the transmission of the synchronous belt to rotate, thereby driving the stirring rod and the stirring plate to rotate, and stirring the water sample in the sampling tube. Finally, the water pump is started to extract the water sample in the test tube, and then the drive motor is started to drive the screw to rotate, thereby driving the two adjustment frames to move horizontally, and then the liquid inlet tube is moved horizontally to the top of the detection tank, and then the water pump is started to inject the water sample into the detection tank, so that the water sample in the detection tank is detected by the detection probe.
