A cultured seawater sampler

Abstract

The invention discloses a sampler for aquaculture seawater, which comprises a base, a cylinder body arranged on the base, a cylinder cover and a sealing cap adapted to the cylinder body, filter holes are arranged on the cylinder cover, and a counterweight is provided at the bottom of the base , the upper part of the cylinder is provided with a handle, the handle is connected with a pull rope, the lower part of the cylinder is provided with a spout, the outlet of the spout is provided with a spout cap, and the upper part of the inner wall of the cylinder is provided with a limiting convex ring along the circumference to limit The gap between the position convex rings forms the water inlet, the spring seat is fixed under the limit convex ring, the spring seat is covered with a spring, the bottom surface of the sealing cap is provided with a spring limit groove, and the upper end of the spring is located in the spring limit groove and is connected with the seal cap. Fixed connection, the lower end of the spring is fixedly connected with the spring seat, when the spring is in a natural state, the sealing cap is located in the water inlet, and the side of the sealing cap is sealingly matched with the water inlet. The invention has a novel and ingenious structure, is convenient to use and carry, has good flexibility in use, is convenient and quick to collect water, and is not easy to spill water samples after collecting water.

Description

technical field [0001] The invention relates to a water quality sampler, in particular to a cultured seawater sampler. Background technique [0002] When carrying out marine aquaculture, the detection of water chemical indicators of aquaculture seawater is an important way to evaluate the quality of aquaculture seawater. Aquaculture must be within the range of reasonable water chemical indicators to survive normally. Therefore, it is of great significance to detect the water chemical indicators of aquaculture seawater. [0003] At present, a sampler is required when sampling aquaculture seawater. For example, the Chinese patent with the authorized notification number CN207600796U discloses a sea water quality sampler. The seawater quality sampler includes a water sample pipeline, a power pump and a sample bottle. The two ends of the power pump are respectively connected with a water sample pipeline, and the water sample pipeline at one end is respectively connected with a ...

AI Technical Summary

Problems solved by technology

This sampler has the following disadvantages: (1) external power equipment (power pump) and power supply are required during use, which is inconvenient to operate and carry, and has poor flexibility in use; (2) water samples can only be transported through water sample pipes, and can only be fixed There are great limitations in the use of water samples in the area; (3) If there are sundries, it is easy to block the water sample pipes
