Description

Technical Field

[0001] The invention relates to the technical field of water quality analysis equipment, in particular to a water quality sampling device for a multi-channel water quality analysis instrument. Background Art

[0002] Multi-channel water quality analyzers are used to analyze the water quality of multiple water samples. The water source and the analyzer are connected through a sampling device. A simple traditional sampling device is a plurality of sampling water pipes, which can transmit different water samples to the inlet of the analyzer. A more complex traditional sampling device has a filtering function, that is, a water filter is installed on each sampling water pipe to filter out impurities in the water sample to prevent impurities from entering the instrument and clogging it, resulting in the adverse consequences of reducing the accuracy of water quality analysis or damaging the analyzer.

[0003] After filtering water samples through the filter for a long time, the existing water quality sampling device is prone to clogging inside, which not only easily affects the efficiency of subsequent filtering of water samples, but also reduces the amount of water samples entering the multi-channel water quality analyzer, thereby reducing the accuracy of water quality detection. At the same time, since different water samples are generally stored in different sample bottles, when the water quality sampling device is used to collect water samples in multiple sample bottles at the same time, the water samples located at the bottom of the inner wall of the sample bottle are difficult to be completely collected, affecting the efficiency of water sample collection.

At this time, due to the shortening of the extended end of the cylinder, the first lever drives the flip rod to rotate, so that the second lever and the transmission rod move downward, and the first piston slides downward, so that the first piston is separated from the input ends of the two L-shaped tubes, and the clean water in the water tank will enter the two U-shaped tubes respectively along the water injection pipe and the two L-shaped tubes, and the clean water entering the U-shaped tube enters the regulating pipe and enters the two corresponding filtering tools along the two water inlet pipes respectively, and the sewage carrying impurities is discharged through the water suction pipe, so as to prevent the residual impurities in the filtering tool from affecting the efficiency of subsequent filtration of water samples, thereby ensuring the amount of water samples entering the multi-channel water quality analyzer, and making the accuracy of water quality detection more accurate.

Due to the action of the second thrust spring, the push-pull rod moves toward the lifting block, so that the second piston and the third piston are separated from the input ends of the two connecting tubes respectively. At this time, the fourth piston is located between the two water inlet pipes. At the same time, due to the extension of the extended end of the cylinder, the connecting rod provides a downward pressing force to the pressing rod, so that the lifting plate moves downward, and the two L-shaped frames are simultaneously provided with a flipping power, so that the push roller pushes the support plate to rise, so that the four water suction pipes are respectively extended into the bottom of the inner wall of the corresponding sample bottle, which is convenient for collecting water samples in multiple sample bottles at the same time, ensuring that the water samples at the bottom of the inner wall of the sample bottle are completely collected, and preventing the efficiency of water sample collection from being affected.
