Embodiment
[0047] Such as Figure 1-4 As shown, the present invention provides a ballast water sample collection device and a depth control sampling method to solve the shortcomings of traditional ballast water collection devices for intelligently collecting surface or fixed area water samples. The purpose of the present invention is achieved by the following technologies:
[0048] 1. Use flexible pipes to realize multi-region water sample collection facing the zigzag cabin;
[0049] 2. Realize the underwater movement of the pipeline through four propellers installed at the end of the pipeline;
[0050] 3. Complete the video monitoring of the ballast water detection area through the underwater camera installed at the end of the pipeline;
[0051] 4. Through the conical hollow net body installed on the top side of the pipe end, the blocking of large aquatic animals and plants in the water body is realized;
[0052] 5. The cleaning of the net body attachments is realized through the opti...

The present invention relates to a ballast water sample collection device and a depth regulation sampling method, the device comprises: a centralized control cabinet composed of an operation platformand a water storage cabin, wherein the operation platform comprises a core controller and a water storage cabin water collection assembly, and the water storage cabin is provided with a water sample extraction port connected to a ballast water quality analysis device; an electric control water suction end which is in water communication with the water storage cabin in the centralized control cabinet and is in collection control communication with the operation platform so that posture regulation and control and multi-area water sample collection in the zigzag cabin body are achieved; the rotating shaft is connected with the centralized control cabinet through a first flexible pipeline and connected with the electric control water suction end through a second flexible pipeline, and the second flexible pipeline is wound on the outer surface of the rotating shaft and is released and recycled through rotation of the rotating shaft. Compared with the prior art, the invention has the advantages that the water suction end is self-cleaned, the water sampling area is freely controlled, space is saved, and winding is prevented.
Description
technical field [0001] The invention relates to the field of ship ballast water treatment, in particular to a ballast water sample collection device and a depth control sampling method. Background technique [0002] Ballast water is water specially injected to maintain the balance of the ship, and it is an important guarantee for the safe navigation of the ship, especially for ships that do not carry an appropriate amount of cargo. Hull vibrations are minimized and propulsion efficiency is maintained. [0003] However, with the continuous development of the ocean shipping market, the volume and scale of ballast water discharge before ships enter and leave ports are also gradually expanding. This long-distance man-made interaction with water bodies has led to the spread of marine harmful organisms to a certain extent. Therefore, how to inspect, identify, test and certify whether the ballast water of relevant ships meets the standards of relevant ballast water management conv...
