Description
Technical field
The invention belongs to aquatic science experimental provision field, specially refer to the hydrostatic test device.
Background technology
Pressure is one of physical agent very important in the water environment, and size is according to Pascal's formula p=ρ gh gained, and habituation is also referred to as hydraulic pressure.Pressure is with the relation between the vertiginous characteristics of the depth of water and gas volume and the pressure in the water, in the process of the evolution of the transformation of fish proportion regulation mechanism and air bladder, plays an important role.
At present, realize that both at home and abroad the several method analysis of pressure is following: Gui Jianfang (1990) experiment belongs to the molecule experiment to fish-egg, and the hydrostatic pressure device adopts industrial booster, has utilized the good pressure transmission property of water, in confined space, carries out; Liao Xiaodong (1995) does not adopt pressurizer only to rely on the water body height change under nature, in laboratory containers, simulates variation in water pressure, pressure receptor effect of altitude, and difference in height has only realized the cms magnitude; The experimental technique of Kim (2011) has been realized the automatic sink-float of net cage, and purpose of design is to hide wave, guarantees net cage safety; Above method has practicality in field separately.But; Current international at home water power utilizes the aspect; Because of the river pressure that effect causes of building a dam changes hydrobiological influence, the influence (especially demersal fishes) that various fish is distributed like the hydraulic pressure that increases, the change of fish behavior under the influence that the fish glue fish are arranged, heavy property fish-egg (the comprising the mandarin sturgeon ovum) nature problems such as hatching, then can't realize through above-mentioned instrument; Reason is following: the hydrostatic pressure device is aspect structure; Water body is strict airtight, and for living body biological, bait that organism is required and oxygen can't get into; And water body can not obtain exchange, and water body is rotten, is unfavorable for live body is launched long-term experiment, therefore is not suitable for experiment made on the living; In addition, confined space is limited, and is inapplicable for the large-scale fish of most adults.
Do not adopt pressurizer under the nature, laboratory containers is aspect the change of water body pressure, and the numerical value interval is narrow and small, influences experiment effect.
Rely on and realize in the water body that there is following shortcoming in the pressure change:
A tests biological behavior and changes difficult the observation and record under water body
B is at the deep water body that has than high current speed, and net cage is wayward.
Summary of the invention:
The object of the present invention is to provide a kind of device that uses law of connected vessels to realize the aquatile hydrostatic test; And utilize this device to carry out aquatile hydrostatic test method; This invention can realize building a dam effect to the hydrobiological influence experiment of live body in the land; Be convenient to bait throwing in and keep water quality good,, be beneficial to the bigger pressure of realization and change interval for long-term experiment can supply possibility.
For realizing above-mentioned purpose, technical scheme of the present invention is:
The present invention includes: water inlet, water inlet pipe, inlet valve, water inlet pipe screen pack, pressure gage, resistance to compression carrier case, perspective window, outlet pipe screen pack, discharge outlet, outlet pipe, serial apopore; Wherein the dual-side of resistance to compression carrier case is equipped with water inlet pipe and outlet pipe; Have the perspective window on the resistance to compression carrier case, on the perspective window pressure gage is housed, resistance to compression carrier case bottom has discharge outlet; Have the serial apopore of a row on the outlet pipe, water inlet pipe is equipped with inlet valve near the inside of resistance to compression carrier case.
Water inlet pipe is equipped with the water inlet pipe screen pack with the position that resistance to compression carrier case contacts.
Outlet pipe is equipped with the outlet pipe screen pack with the position that resistance to compression carrier case contacts.
Utilize this device to carry out aquatile hydrostatic test method, the steps include:
One, preparation before the experiment: water inlet, delivery port, valve are in closed condition, and carry out the data acquisition that biology is measured, biochemical sample is sampled to testing biology;
Two, experimentize: open inlet valve; After water inlet injects the depth of water greater than the organism height, close inlet valve, open the perspective window on the resistance to compression carrier case, put into the experiment biology; Shut the perspective window, open in the corresponding serial delivery port of experiment desired height h 11
i, serial delivery port below this height h is Close All then, calculates pressure P by P=ρ gh; Open inlet valve; Be filled to experiment desired height h, height is series delivery port 11 places mark at the outlet pipe place, from pressure gage, reads actual pressure at the bottom of the resistance to compression carrier case; Adjustment water inlet water intake velocity makes it to go out water speed less than serial delivery port maximum;
Three experimental data collections: bait gets into resistance to compression carrier case by water inlet with current, through the adaptive behavior of perspective window observation experiment biology to pressure, after experiment finishes; Close inlet valve; Open the little discharge outlet of serial delivery port lowest order, when water level reaches this discharge outlet height, regulate once more the casing depth of water to organism highly quite after; It is biological to take out experiment, image data.
The clean system of cleaning politics, economics, organization, and ideology: water inlet stops into water, opens inlet valve and discharge outlet, and with the water emptying, cleaning resistance to compression carrier case is closed water inlet, serial delivery port, inlet valve then, uses in order to experiment next time.
Good effect of the present invention is:
1, the utilization law of connected vessels realizes that on land water body pressure changes, and the effect that realizes building a dam is to the hydrobiological influence experiment of live body.
2, the change of realization water body pressure helps in bait throwing in and keeps water quality good the utilization law of connected vessels on land, for long-term experiment made on the living realizes providing adequate condition.
3, the utilization law of connected vessels realizes that on land water body pressure changes, and it is interval to help realizing that bigger pressure changes.
4, the utilization law of connected vessels realizes that on land water body pressure changes, and helps ethological observation.
