Embodiment Construction

[0029] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0030] Such as figure 1 , figure 2 and image 3 Shown, a kind of portable seawater sampling bag that is used for fishery research, comprises: the sample plastic film bag 1 of spherical structure, and sample plastic film bag 1 is connected with cable 3 and counterweight 4, is characterized in that, sample plastic film bag 1 includes an inner membrane 6 and an outer membrane 7 nested together. The outer wall of the inner membrane 6 is spirally wound with a plastic film tube 5. The plastic film tube 5 is connected to the pump body through the pump tube 2. The pump body can pump seawater into the plastic film Inside the tube 5; by using plasti...

Abstract

The invention discloses a portable seawater sampling bag for fishery study. The portable seawater sampling bag comprises a sample plastic film bag with spherical structure, the sample plastic film bagis connected with a cable and a counter weight, the sample plastic film bag comprises the inner film and the outer film which are sleeved together, the outer wall of the inner membrane is spirally wound with a plastic film tube, the plastic film tube is connected with a pump body through a pump tube, and the pump body can pump the seawater into the plastic film tube; two ends of the diameter of the sample plastic film bag with spherical structure are respectively a first end and a second end, the outer film, near the first end, is provided with a first through hole, the inner film, near the second end, is provided with a second through-holes; when the plastic film pipe is fully filled with seawater, a plastic film tube with a tight saturate state which is supported by seawater in the plastic film tube is formed, the plastic film tube can open up the sample plastic film bag in the saturate state.

Description

technical field [0001] The invention relates to a seawater sampling technology, in particular to a portable seawater sampling bag used for fishery research. Background technique [0002] Seawater sampling is required for marine research, especially marine fisheries research. Throw the seawater sampling device down in the sea at a certain depth, control the depth of the seawater sampling device in the water by releasing the cable to control the length of the cable, and then load the seawater at the corresponding depth position. However, in the prior art, the overall components of the seawater sampling device are complicated and cumbersome, and it is difficult to move on a ship and requires multiple people to operate to complete the sampling work. The seawater taken out by the sampling device of the prior art also needs to be packed into special containers for storage so as to be tested ashore. The sampling device is not disposable, and the seawater sampled at multiple point...
