Description
Technical field
The present invention relates to a kind of tank system, and in particular to one kind is applied to the research of fish-egg motion hydraulic characteristic, reservoir
Dispatching influences the fish-egg exercise test tank system of research, the research of fish early stage calculation of natural resources etc. on fish, belongs to ecological waterpower
Learn experimental technique field.
Background technology
Fish-egg drifting motion is the important stage of fish early development, and the successful hatching and resource for being related to fish ovum seedling are mended
Fill.In natural river, how fish-egg is moved, how fish-egg density is distributed, river topography and hydrodynamic condition are moved such as to fish-egg
What is acted on, all by the defeated shifting for influenceing fish-egg and final home to return to.Therefore, it is appreciated and understood by hydrodynamic force of the fish-egg in natural river course special
Property and the characteristics of motion, the protection of fish resources, spawning ground are repaired and the work such as ecological dispatching effect assessment is most important, meanwhile,
Also theoretical foundation is provided by the science estimation for the accurate supposition of fish spawning ground position and early stage stock number.
At present, traditional hydraulics test tank (Tang Mingying, Huang Delin, Huang Li are used the experimental study of fish-egg motion more
The such as chapter grass, green grass or young crops, silver carp, bighead ovum hydraulic characteristic are tested and its in reservoir area of Three Gorges incubation condition tentative prediction water conservancy related fisherieses,
1989,4:26-30；Drift characteristic research aquatic life of the two kinds of sturgeon ovum of the such as Luo Jia, Shi little Tao, Liu Defu in uniform flow field
Thing journal, 2013,37 (5):978-981).
But found through practice, there is following defect in traditional hydraulics test tank：

Button, electromagnetic flowmeter 14, frequency conversion centrifugal pump 15 and magnet valve of pipe 16 are automatically turned on, and frequency conversion centrifugal pump 15 is transported in low frequency
Turn.
Then, the flow parameter 0.054m inputted in tank intelligent switch operating platform interface needed for experiment3/ s, and point
ACK button is hit, the frequency of frequency conversion centrifugal pump 15 slowly will adjust frequency corresponding to corresponding discharge.
Finally, by clicking on the open and close button of Spiralism type tail-gate 7, the aperture of slow regulation Spiralism type tail-gate 7 treats tank
When interior water level rises to experiment preset water level 0.9m, stop the switching manipulation of Spiralism type tail-gate 7, terminate the tune of tank stage-discharge
Control.
Step3：Fish-egg delivers flow and time-controllable
Fish-egg is delivered into the most upstream side that slide rail 5 of the track sled 21 along sink top is moved to Rectangular Water Trough groove body 6, adjusted
The putting position of whole fish-egg conveyer 18 at different levels, it is ensured that do not fallen off in fish-egg transmit process onto ground.
The lifting button that fish-egg delivers elevating lever 19 is clicked on, the hopper outlet that L-type fish-egg is delivered into funnel 20 rises to the water surface
Place, adds quantitative fish-egg (500ml, about 20000 fish-eggs), then in tank intelligent switch operating platform interface in the sink
The frequency 800Hz and duration 5h of the motor of fish-egg conveyer belt 180 are inputted, the flow (individual/second) for delivering fish-egg reaches pre-
If being worth (500 ± 50/second), after after operation 20 minutes, fish-egg circulates the stability of flow of input and reaches preset value.
Step4：Fish-egg exercise test is measured
Complete tank stage-discharge and fish-egg is delivered after flow and the regulation and control of time, section 10m downstream is delivered in distance
Position, sets fish-egg measuring frequency section, and acoustic Doppler velocimetry (ADV) is set up on the slide rail 5 of sink top, in tank side
Slide rail 5 on set up high-speed camera, measurement tank flow field gathers fish-egg motion trace data, and research fish-egg particles populations exist
The characteristics of motion under the conditions of low flow velocity.
Fish-egg quiescent sedimentation experiment is carried out, process of the test and operating procedure are as follows：
Step1：Preparation before experiment
Check flexible filter net 11, fish-egg conveyer belt 180, fish-egg baffle plate 181 flexible screen cloth it is whether damaged, if any broken
Damage, change in time.
Check that L-type fish-egg reclaims funnel 10 and L-type fish-egg delivers whether funnel 20 has by foreign matters from being blocked, if any blocking, use
Clear water rinses funnel, excludes foreign matter.
Check whether L-type fish-egg dispensing funnel 20 and the connection of fish-egg dispensing elevating lever 19 loosen, if any loosening, tighten.
Clear water is filled in cistern 13, the hose 185 of fish-egg conveyer 18 is connected to running water pipe, in case examination
Test.
Before the exercise test of different fish fish-eggs or different materials model fish-egg is carried out, calibration fish-egg flow and transmission are needed
Relation between translator frequency.
Step2：Tank water level management
Enter tank intelligent switch operating platform, activation intelligence in remote terminals such as desktop computer, tablet personal computer or mobile phones
Switching system.
First, smooth water test pattern is selected, upstream backwater gate 4 is automatically turned on, downstream backwater gate 8 is closed automatically, point
Hit into water button, electromagnetic flowmeter 14, frequency conversion centrifugal pump 15 and magnet valve of pipe 16 are automatically turned on, and frequency conversion centrifugal pump 15 is in
Low frequency is operated, and slowly the clear water in cistern 13 is evacuated in Rectangular Water Trough groove body 6.
When water level in tank rises to experiment preset water level 0.9m, the X button of frequency conversion centrifugal pump 15 is clicked on, is clicked on
The X button of upstream backwater gate 4, forms smooth water test condition, terminates the regulation and control of tank water level.
Step3：Fish-egg hydrostatic settling velocity is measured
Fish-egg is delivered into slide rail 5 of the track sled 21 along sink top and is moved to Measure section, the slide rail 5 in tank side
Upper erection high-speed camera.
The lifting button that fish-egg delivers elevating lever 19 is clicked on, the hopper outlet that L-type fish-egg is delivered into funnel 20 rises to the water surface
Place, quantitative fish-egg (50ml, about 2000 fish-eggs) is added in L-type fish-egg delivers funnel 20.
High-speed camera is opened, the track data of fish-egg quiescent sedimentation is gathered, research fish-egg particles populations are in hydrostatic condition
Under settlement law.
As can be seen here, by setting L-type fish-egg to deliver, funnel 20, L-type fish-egg reclaim funnel 10 to the present invention and fish-egg is transmitted
(fish-egg that L-type fish-egg recovery funnel 10 is reclaimed can be sent to L-type fish-egg and deliver funnel 20 device 18 by fish-egg conveyer 18
In), the automatic cycle that fish-egg is delivered, reclaims and transmitted not only is realized, and realizes fish-egg and delivers flow and lasting dispensing
Time it is adjustable controllable, while also effectively reducing the damage ratio of fish-egg.
In addition, the present invention is by setting movable fish-egg to deliver track sled 21 and multistage fish-egg conveyer 18,
Realize dispensing of the fish-egg in the laterally-distinct position of tank, during experiment can by change deliver between section and measuring frequency section away from
From metastable motion process after the diffusion process and uniform diffusion before observation fish-egg unsteady motion.
It should be noted that the invention is not limited in any way for above-described embodiment, all use equivalent substitutions or equivalent change
The technical scheme that the mode changed is obtained, all falls within protection scope of the present invention.
