Support type water sample collecting device

Abstract

The invention relates to a support type water sample collecting device which comprises a sampler, a telescopic rod, a rotating joint, a rotating wheel and a tripod; the sampler is connected with the first telescopic rod through a rotating wheel and a first rope, and the depth of the sampler in water is controlled by adjusting the length of the first rope through a handle; the tripod and the first telescopic rod are fixed through the rotary interface and the second telescopic rod; the first telescopic rod and the second telescopic rod stretch out and draw back to the needed length through the buckles. Sampling personnel can rotate the first telescopic rod to control the direction; The second rope provides supporting force for the first telescopic rod to reinforce the device. The device is suitable for collecting water samples of small rivers, ditches and the like with the width within 10m, and can effectively avoid water flow disturbance caused by ship movement of shallow rivers, ditches and the like. The device is convenient to disassemble, assemble and carry, simple and easy to operate, and ensures smooth collection of water samples.

Description

technical field [0001] The invention relates to the technical field of environmental sampling, in particular to a water sample collection device. Background technique [0002] The water quality sampling instrument that generally uses now has the manual water sampling form, the electric pump water sampling form and the pneumatic pump water sampling form. Since the latter two forms of water collection equipment are more complicated, costly, and complicated to operate, many universities and companies use manual water collection for collection. [0003] The general manual sampling process needs to reach the sampling point by boat or other equipment, but for some narrow or shallow rivers, boats cannot enter, or the water quality changes in a short time due to the entry of boats, resulting in the collection of water samples. not representative. In the actual operation process of the present invention, it can effectively prevent the upturning of the bottom mud and the change of t...
