1 hydrostatic pressure device is aspect structure, and 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 2 natures, laboratory containers is aspect the change of water body pressure, and the numerical value interval is narrow and small, influences experiment effect.
3 rely in the water body and to realize that pressure changes and have following shortcoming:
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 purpose of the utility model is to provide a kind of law of connected vessels that utilizes; Regulate the aquatile hydrostatic test device of the pressure of resistance to compression carrier case through outlet pipe delivery port height; This device can realize that water body pressure changes on land, for long-term experiment made on the living realizes providing adequate condition.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
The utility model comprises: 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, has the serial apopore of a row on the outlet pipe, and 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.
The good effect of the utility model is:
1, this device realizes building a dam effect to the hydrobiological influence experiment of live body in the land.
2, be convenient to bait throwing in and keep water quality good, for long-term experiment can supply possibility.
3, it is interval to help realizing that bigger pressure changes.
4, the experiment in the land helps ethological observation.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing 1.
The utilization law of connected vessels realizes that the device of aquatile hydrostatic test comprises: water inlet 1, water inlet pipe 2, inlet valve 3, water inlet pipe screen pack 4, pressure gage 5, resistance to compression carrier case 6, perspective window 7, outlet pipe screen pack 8, discharge outlet 9, outlet pipe 10, serial apopore 11; Wherein the dual-side of resistance to compression carrier case 6 is equipped with water inlet pipe 2 and outlet pipe 10; Have perspective window 7 on the resistance to compression carrier case 6; On the perspective window 7 pressure gage 5 is housed; Resistance to compression carrier case 6 bottoms have discharge outlet (9), have the serial apopore 11 of a row on the outlet pipe 10, and water inlet pipe 2 is equipped with inlet valve 3 near the inside of resistance to compression carrier case 6.
Water inlet pipe 2 is equipped with water inlet pipe screen pack 4 with the position that resistance to compression carrier case 6 contacts.Outlet pipe 10 is equipped with outlet pipe screen pack 8 with the position that resistance to compression carrier case 6 is connected.
This each junction of device, apopore and the maintenance of valve seal property are good.
Water inlet pipe 2 and outlet pipe 10, for compression-resistant material is processed, diameter 0.3 ~ 1m, sealing is good.Current and bait flow into water inlet pipe 2 through water inlet 1, guaranteed in the resistance to compression carrier case 6 that the experiment biology can be ingested and in long term survival and the casing water quality good.Open and close the water level of controlling water inlet pipe 2 through inlet valve 3.Water inlet pipe screen pack 4 is processed for the iron wire material with outlet pipe screen pack 8, is installed in the junction of water inlet pipe 2 and outlet pipe 10 and resistance to compression carrier case 6 respectively, is to test biological water inlet pipe 2 and the outlet pipe 10 of getting into for preventing respectively, guarantees the accuracy of testing.The mesh designing requirement of screen pack is less than fish body width with greater than the bait diameter, and assurance experiment biology can not get into water inlet pipe and blow water pipe while bait and can pass through mesh.
Pressure gage 5 is connected on the perspective window 7, the convenient pressure of pressure gage position of accurately reading.Resistance to compression carrier case 6 usefulness compression-resistant materials are processed, and sealing is good.Perspective window 7 possesses out and closes function, is used for the observation experiment material to the reaction of hydraulic pressure and putting into of experiment material, can all be provided with all around.Discharge outlet 9 is positioned at bottom half, is used for the casing draining, the effect of leaking water when playing clean box body.Series apopore 11 links to each other with outlet pipe and communicates, and with outlet pipe junction good seal.Be provided with at a distance from 1m or 2m vertical height along outlet pipe is every, indicate height, be numbered 111,112,113 from low to high ... 11i plays and regulates depth of water effect, regulates the pressure in the resistance to compression carrier case with this, and other has drainage.Series apopore 11 is installed on the outlet pipe outside, leans on the casing far-end.Whenever at a distance from 1 ~ 2m an apopore is installed from outlet pipe and casing junction, until delivery port.Apopore diameter 12 ~ 15cm is connected in outlet pipe, is opened on the outlet pipe both sides, and the outlet pipe current are discharged through apopore, and when operation experiment water inlet discharge less than the apopore water yield.Bait gets into casing from water inlet with water inlet pipe under current and action of gravity.
200 ~ 300m or higher vertical height can adopt the mode of rising from the level ground and setting up the stage.But from angle economic and safety; 200 ~ 300m or higher vertical height do not adopt the mode of rising from the level ground; Can lay along the mountain through the steel pipe that 0.3 ~ 1m is thick, from the foot of the hill to the mountain top, no matter broken line or straight line; As long as vertical range is 200 ~ 300m, so but this covering device sets up the mountain of high about a 200 ~ 500m of addressing for relying on.For the purpose of resistance to compression and safety, resistance to compression carrier case can be selected to be built in underground, and casing removes perspective outside window, and the barrier resistance to compression is all arranged all around, alleviates the pressure that resistance to compression carrier case bears.
