Water sample collector provided with response acceleration mechanism

Abstract

The invention relates to a water sample collector and solves a problem of inconvenient opening of a sampling bottle. The water sample collector provided with a response acceleration mechanism includes a sampling bottle, an inhaul cable, a weight and the response acceleration mechanism, the response acceleration mechanism comprises a vertical cylinder, an upper driving rod and a lower driving rod, the top wall of the sampling bottle is provided with an upper one-way valve, the bottom wall of the sampling bottle is provided with a lower one-way valve, the upper one-way valve and the lower one-way valve respectively comprises a channel and a valve core arranged in the channel, the weight is arranged at the bottom of the sampling bottle, the cylinder comprises a cylinder body and a piston connected to the inside of cylinder body in a sliding seal manner, a sealed gas cavity is formed between the cylinder body and the piston, the cylinder body is fixedly connected with the sampling bottle, the lower end of the lower driving rod traverses through the gas cavity and then is connected with the piston, the upper end of the lower driving rod is connected with the valve core of the lower one-way valve, the upper end of the upper driving rod is connected with the valve core of the upper one-way valve, and the lower end of the upper driving rod is connected with the valve core of the lower one-way valve. The water sample collector has the advantages of automatic opening and closing of the sampling bottle, and short response time of the opening and closing.

Description

technical field [0001] The invention relates to a water sample sampler, in particular to a water sample collector provided with a response acceleration mechanism. Background technique [0002] In the testing of water quality, it is one of the important links to ensure that the water samples taken are representative, and the representativeness of the samples depends on the sampling technique and the preservation of the samples. Water sampling is done with a water sampler. A water sampler is disclosed in the Chinese patent application No. 2008100567581, the publication date being July 16, 2008, and the patent document titled "A Lake and Reservoir Layered Water Sampler". Existing water samplers all include a sampling bottle, a cable for pulling sampling and a weighted block for sinking the sampling bottle. When in use, the sampling bottle is lowered to the corresponding depth through the weight block, and then the water enters the sampling bottle, and then the sampling bottle...

AI Technical Summary

Problems solved by technology

[0003] The first purpose of the present invention is to provide a water sample collector with a response acceleration mechanism that can automatically open and close the sampling bottle and has a short opening and closing response time, which solves the problem of opening the sampling bottle by pulling the rope The problem of the inconvenience of combining the sampling bottle

[0004] The second purpose of the present invention is to provide a water sample collector that can conveniently make the sampling bottle located at the required water depth position and is provided with a response acceleration mechanism, which solves the problem of adding a weight block to the existing water sample sampler. The laborious problem of using the weight to make the actual depth of the sampling bottle equal to the desired depth
