Sampler for aquaculture seawater

Abstract

The invention discloses a sampler for aquaculture seawater, which comprises a base, a cylinder arranged on the base, a cylinder cover matched with the cylinder body and a sealing cap. The cylinder cover is provided with a filtration pore in the bottom, a counterweight block is arranged at the bottom of the base, the cylinder body is provided with a handle at the upper portion, and the handle is connected to a lifting rope, the cylinder body is further provided with a water outlet nozzle at the lower part of the cylinder body, a water outlet nozzle cap is arranged at an outlet of the water outlet nozzle; a limiting convex ring is arranged on the upper portion of the inner wall of the cylinder in a circumferential direction, a water inlet is formed in the gap formed at the middle of the limiting convex ring, the limiting convex ring is fixedly provided with a spring seat below, which is sleeved with a spring, a spring limiting groove is formed in the bottom surface of the sealing cap, the upper end of the spring is located in the spring limiting groove and fixedly connected with the sealing cap, and the lower end of the spring is fixedly connected with the spring seat. The sealing cap is located in the water inlet when the spring is in a natural state, and the side surface of the sealing cap is in sealed fit with the water inlet. The sampler for aquaculture seawater is novel andingenious in structure, convenient to use and carry, good in flexibility of use, convenient and fast in water collection, and water samples collected are difficult to spilled out.

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
