Water quality sampler with long-distance multi-fixed-depth function

Abstract

The invention discloses a water quality sampler with a long-distance multi-fixed-depth function. The sampler comprises an underwater gliding piece and fixed-depth collecting pieces; the underwater gliding piece comprises an active gliding piece and an auxiliary gliding piece; each fixed-depth collecting piece is connected to the active gliding piece, the auxiliary gliding piece is connected to the fixed-depth collecting piece, the fixed-depth collecting piece comprises a collecting shell, a sinking collecting part, a floating collecting part and a pipe collecting part, the collecting shell is connected to the active gliding piece, and the sinking collecting part, the floating collecting part and the pipe collecting part are all arranged on the collecting shell; the active gliding piece and the auxiliary gliding piece are used for converting buoyancy and gravity into power for forward movement so as to drive the plurality of sets of fixed-depth collecting pieces to move to a preset position to collect a plurality of water samples at the same cross section at the same time. The water quality sampler is reasonable in design, long in moving distance, low in energy consumption, safe in moving and water sample collection process, and capable of carrying out multi-fixed-depth multi-point water sample collection on the same section so as to improve the water quality detection accuracy.

Description

technical field [0001] The invention relates to the technical field of water quality samplers, more specifically, the invention relates to a water quality sampler with long-distance multiple depth-fixing functions. Background technique [0002] With the rapid development of urban and rural economies, chemical and chemical products are widely used in industrial and agricultural production processes, and toxic and harmful substances such as waste water, waste gas, and solid waste are discharged in large quantities, making surface water pollution such as rivers and lakes a very severe environment. question. At present, the water quality sampler usually uses a rope to tie the sampling bottle and throw it into the water for water sample collection. Since the bottle is filled after being submerged in the water, it can only collect shallow water samples, and it is difficult to apply to deep and wide waters. Sampling is not conducive to the smooth progress of environmental monitori...

AI Technical Summary

Problems solved by technology

However, at present, the water quality sampler requires workers to go to the water collection place to take water one by one at different depths and locations on the same end face, which makes the water collection process complicated, the water collection frequency is high, and it is dangerous. work has brought great inconvenience
