Abstract

The invention discloses an underground water invertebrate net capturing sampler and a manufacture method thereof. The underground water invertebrate net capturing sampler comprises a frustum filter net, a cylindrical filter net, sleeve I, sleeve II, an internal-thread connector and a sample bottle; the lower portion of the frustum filter net is fixedly connected with the upper portion of the cylindrical filter net through the sleeve I, the sleeve II is connected inside the lower portion of the cylindrical filter net, the internal-thread connector is connected inside the bottom of the sleeve IIand is connected with the sample bottle, the frustum filter net is equal to the cylindrical filter net in pore diameter, an upper opening of the frustum filter net is greater than its lower opening in diameter, a plurality of ropes are connected to the upper portion of the frustum filter net, ends of the ropes are tied via locks. The underground water invertebrate net capturing sampler is simplein structure, can provide sampling analysis for underground invertebrate condition with no disturbances and can guarantee sampling randomness; underground animal species can be judged accurately to reflect underground water eco-environments, and the manufacture method is simple and low in cost.

Description

technical field [0001] The invention relates to the technical field of hydrogeological exploration, and more specifically relates to a groundwater invertebrate netting sampler and a manufacturing method thereof. Background technique [0002] Due to the presence of certain cracks and pores in the underground aquifer, especially the bedrock aquifer with calcareous conglomerate and karst fractures, there are large crack channels and spaces, plus the infiltration and recharge of precipitation and surface water, and the existence of artificial drilling. The connectivity makes the groundwater have a certain amount of dissolved organic matter and dissolved oxygen, which can accommodate the survival of groundwater invertebrates and maintain their growth and development. This kind of groundwater biological population is usually small in size, about a few millimeters, with slow metabolism and low reproduction rate, but has a long life span. Together with protists, bacteria, archaea, a...
