Seawater quality sampling device with different depths for ocean monitoring

Abstract

The invention discloses a seawater quality sampling device with different depths for ocean monitoring. The device comprises a mounting plate; a mounting bracket is fixedly connected to the mounting plate; a cable take-up roller is rotationally connected to the mounting bracket; a power mechanism is arranged between the cable take-up roller and the mounting plate; a supporting frame is fixedly connected to the mounting bracket; the free end of the cable is fixedly connected with a connecting block; the other end, away from the cable, of the connecting block is fixedly connected with a sampler;six sampling grooves are formed in the upper end of the sampler in a penetrating mode, plugging mechanisms are arranged in the six sampling grooves, four connecting rods are fixedly connected to the bottom of the sampler, a balancing weight is fixedly connected to the bottoms of the four connecting rods jointly, and standby power equipment connected with the cable take-up roller is arranged on themounting plate. The seawater sampling device is reasonable in structure, capable of sampling seawater at different depths at a time, lower in production cost, better in practicability and safer.

Description

technical field [0001] The invention relates to the technical field of seawater sampling, in particular to a seawater quality sampling device with different depths for ocean monitoring. Background technique [0002] The total area of ​​the earth's surface ocean is about 360 million square kilometers, accounting for about 71% of the earth's surface area. The deep sea area is rich in oil, natural gas and other oil and gas resources. It is the largest potential strategic resource base on the earth that has not been fully understood and utilized by humans. With the intensification of energy problems, the importance of deep-sea energy development and research has become increasingly prominent. Seawater sampling is the first step in finding and exploring marine oil and gas resources and microbial resources. Seawater quality sampling is also the basis for marine pollution detection. [0003] Seawater pressure refers to the force exerted by a seawater column of a certain height on ...

Problems solved by technology

[0004] However, when the existing seawater quality sampling devices on the market are used, it is impossible to sample seawater at different depths at one time. It is necessary to put the sampler into the sea for sampling many times. The sampling efficiency is low, and the loss of the sampler is relatively large.

[0005] The prior art discloses a seawater quality sampling device with the application number CN201910244419.4. Although it solves the problem of one-time sampling of seawater at different depths, the sampling control of seawater is controlled by electromagnetic valves, etc., and the water pressure is relatively high in deep seawater. Special protection or processing is required for the solenoid valve, which increases the production cost and difficulty of the sampling device, and there is no spare power equipment to replace the drive motor after it is damaged. It is time-consuming, laborious and dangerous to turn the cable take-up roller manually. Therefore, We designed a seawater quality sampling device with different depths for ocean monitoring to solve the above problems
