Near-shore ocean water quality detection sampling device capable of collecting water sources of different depths

Abstract

The invention discloses a near-shore marine water quality detection sampling device capable of collecting water sources of different depths, the near-shore marine water quality detection sampling device comprises a floating platform, a storage battery, a servo motor, a third bevel gear and a discharge pipe, the bottom of the floating platform is fixedly provided with an outer box body, the outer box body is internally provided with the storage battery and the servo motor, and the front side of a vertical plate is provided with a limiting block; and a sealing plug is arranged at the bottom of the vertical plate, the other end of the steel wire rope is connected with the second rotating shaft, and the inner box body is arranged in the outer box body. According to the near-shore marine waterquality detection sampling device capable of collecting water sources of different depths, the screw rod is in threaded connection with the three connecting plates, and the connecting blocks made of rubber are arranged on the outer sides of the connecting plates, so that when the screw rod rotates, the connecting plates can be driven to move together, and water sampled in the earlier stage is pushed; sample water in different depths is stored in a classified mode, subsequent detection and comparison are facilitated, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field related to oceans, in particular to a sampling device for detecting water quality in coastal oceans that can collect water sources at different depths. Background technique [0002] There are many species in the ocean, not only fish, but also plants and minerals, and the ocean can be divided into offshore and deep sea according to its depth. Whether it is offshore or deep sea, people pay special attention to changes in the marine ecological environment. In order to better To understand marine water resources, seawater is usually sampled, tested through the water samples taken, and judged based on the test results. Therefore, the use of sampling devices is essential in the detection of marine ecological environments. [0003] But existing marine water quality sampling device still has some deficiencies in use, for example: [0004] 1. When in use, it is not convenient to sample seawater at different depths a...

Problems solved by technology

[0006] The object of the present invention is to provide a kind of near-shore marine water quality detection sampling device that can collect water sources of different depths, so as to solve the problem that the current sampling devices on the market proposed by the above-mentioned background technology are not convenient for sampling seawater of different depths according to the detection requirements, that is, It is inconvenient to adjust the sampling range of the sampling device, which leads to certain limitations in the use of the sampling device, and also reduces the detection effect of water quality. The water is classified and stored, so it is not convenient to detect and compare water at different depths, which reduces the detection efficiency, and the algae in the ocean will be encountered during the sampling process, so when sampling near the algae, it is easy to cause the algae and seawater to flow from the device together. If the inlet enters, it will cause the water inlet pipe to be blocked, so that the normal sampling cannot be performed, which reduces the practicality of the sampling device.
