Embodiment 1

[0021] The cylindrical side wall 9 of this embodiment is transparent and can be used for supporting structures, such as plexiglass, with an inner diameter of 350 mm, a side wall thickness of 15 mm, and a height of 500 mm. Base plate 14, flange 7, top plate 5 and tee pipe material are materials with pressure-resistant support structure and anti-seawater corrosion, such as common commercially available PVC (polyvinyl chloride); the diameter of base plate 14 is 470mm, thickness is 25mm, The pressure regulating hole 11 and the water inlet and outlet hole 12 are symmetrically opened at a distance of 100mm from the center of the bottom plate 14; the inner diameter of the flange 7 is 380mm, the outer diameter is 450mm, and the thickness is 25mm; the O-shaped sealing ring 6 is non-toxic and seawater-proof Corroded materials, such as rubber, have an inner diameter of 380mm, an outer diameter of 400mm, and a thickness of 2mm; the top plate 5 has a diameter of 470mm and a thickness of 25m...

Embodiment 2

[0024] The difference between this embodiment and embodiment 1 is:

[0025] Such as figure 1The visual pressure regulating water tank shown in the experiment is used to test the waterproof performance of the waterproof casing of the underwater camera. Put the color-changing silica gel that has been dried for 24 hours into the waterproof casings of three underwater cameras of the same specification, put the waterproof casings into the observation room fixed on the bottom plate 14, cover the flange 7 with the O-ring 6, and then cover it The top plate 5 closes the observation room, and then tightens the nut 4 on the stud bolt 8; after sealing the laboratory observation room safely, open the water inlet switch 17 and the pressure relief valve 3, and inject water into the laboratory observation room through the water inlet and outlet holes 12 Sea or fresh water required. When water flows out of the pressure relief valve 3, close the water inlet and the pressure relief valve, obse...

Abstract

The invention relates to simulation experiment devices, in particular to an observable pressure-regulating water case for experiments. The observable pressure-regulating water case comprises a pressure-regulating device and an observation room. The observation room comprises a top plate, a flange, a cylindrical side wall and a bottom plate. Two ends of the cylindrical side wall are connected with the flange and the bottom plate in a sealing manner respectively. The flange is connected with the top plate in a sealing manner. A water inlet and a pressure-regulating hole are reserved on the bottom plate respectively, the water inlet is communicated with a water source, and the pressure-regulating hole is communicated with the pressure-regulating device. A first pressure gauge and a pressure relief valve which are communicated with the observation room are mounted on the top plate respectively. By the observable pressure-regulating water case, pressure at 60 meters depth in water can be simulated indoors, experiments of associated marine lives and physical materials can be performed, and the observable pressure-regulating water case has the advantages of visibility, simple structure, convenience in operating, low cost, high safety, wide application range and the like.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a visual pressure regulating water tank for experiments. Background technique [0002] Mariculture activities in my country are usually carried out within 15m offshore, and have begun to expand to 50m water depth in recent years. However, with the increase of water depth, the water pressure has increased significantly. The corresponding growth conditions of aquaculture objects and the supporting application of aquaculture equipment need to be studied urgently. Carrying out traditional field experiments out to sea for research in this area requires ship support, multi-person participation, high cost, inability to observe in time, difficulty in recovery, poor stability, and weak anti-risk ability; while indoor experiments, it is difficult to simulate the pressure environment at a water depth of 50m. The results are less reliable. It is difficult to carry out aquaculture experiment...
