Specific embodiment
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
Such as Fig. 1-2, in a kind of plane, fish swims the measuring equipment of resistance, including tank 1, floating ball tank 2, little ball 3, lightweight
Aluminium chassis 4, scalable stiff shaft 5, strain gauge 6, fish body model 7 to be measured and bed course 8.Wherein, floating ball tank 2 is two, point
Tank 1 both sides are not positioned over, and 4 two ends of lightweight aluminium chassis are respectively connected by sucker 13 with two little balls 3 respectively, horizontal positioned
On tank 1, little ball 3 is floated in floating ball tank 2, is played a supporting role；4 central part of lightweight aluminium chassis is connected with can be stretched
Contracting stiff shaft 5, rod member hardness are sufficiently high, and sufficiently fine, therefore measurement result are affected less.5 bottom of scalable stiff shaft
Portion connects fish body model 7 to be measured by bolt, as rod member has scalability, therefore, it is possible to measure the resistance of different water depth
Power；3 strain gauges 6 are placed horizontally on tank 1 and two floating ball tanks 2 respectively, are connected with lightweight aluminium chassis 4 by cord
Connect, strain gauge 6 and lightweight aluminium chassis 4 is in same level by bed course 8.
Further, the scalable stiff shaft 5 can be carried out slidably on lightweight aluminium chassis 4.
Further, 4 side of lightweight aluminium chassis is equipped with angulation equipped with rule 12 with 6 connection of strain gauge
Device 10, movable beam centre are equipped with air-bubble level 11.
Further, three sides of the lightweight aluminium chassis 4 are connected with strain gauge 6 by cord, can both ensure measurement knot
Really, the stability of whole measurement apparatus can be maintained again.
Further, the floating ball tank 2, little ball 3, lightweight aluminium chassis 4, scalable stiff shaft 5 are all independent parts
Part, with detachability, can be used to carry out drag measurement on the tank of different types.
Further, the side of the floating ball tank 2 is provided with pipeline valve 9, can connect two by pipeline and float
Ball water tank 2 has identical water level to ensure two water tanks.
Further, when fish body model 7 to be measured is in irregular shape or deviates the centre of lightweight aluminium chassis 4, gently
Matter aluminium chassis 4 now can manually be slowly increased water in lower end floating ball tank 2 in Transverse to the flow direction run-off the straight
Amount, by observing air-bubble level 11 come leveling framework.
Further, in a kind of plane, fish swims the method for measurement of resistance, sets up fish body model by 3D scannings, in conjunction with video recording
The different shape of fish body on the movement locus of extraction, using 3D printing technique, produces the fish body model 7 to be measured of different attitudes,
It is fixed on framework, is then placed in measuring in tank 1, quantifies the fish trip resistance on different motion track.
The course of work of the present utility model and operation principle are：
This example specific embodiment is：The floating ball tank of 1 both sides of tank, before experimental trough 1 discharges water, is installed first
2, water tank is installed to and is close to 1 side wall position of tank, then connect the pipeline valve 9 of both sides water tank by external hose, used
Law of connected vessels makes two cistern water levels equal.After the water surface stablize static after, turn off valve, remove flexible pipe.According to fish body to be measured
The weight of model 7, the little ball 3 of 4 specification identicals being of moderate size of selection, the standard of selection is to be put in ball float when little ball 3
When supporting lightweight aluminium chassis 4 and fish body model 7 to be measured in water tank 2, it is desirable to which four little balls are as far as possible little by water flooding volume.So
Discharge water in backward tank 1, when the water surface stably after, fish body model to be measured is put in water.By rule 12 and scalable hard
Matter thin bar 5 is determining the position of fish body model to be measured.When fish body mould shapes to be measured rule is symmetrically and positioned at lightweight aluminium chassis 4
During centre, as both sides cistern water level is equal, now lightweight aluminium chassis 4 are already up to the standard state, when fish body mould to be measured
Type is in irregular shape or during centre that is deviateing lightweight aluminium chassis 4, lightweight aluminium chassis 4 incline in Transverse to the flow direction
Tiltedly, the water yield is manually slowly increased in now needing to a floating ball tank 2 of lower end, observes air-bubble level 11, until level
Then stop adding water after bubble is placed in the middle, now lightweight aluminium chassis 4 are in horizontality.Connection strain gauge 6 and lightweight aluminium chassis 4, lead to
Crossing increases the bed course 8 of different-thickness, makes strain gauge 6 with lightweight aluminium chassis 4 in same level.Above-mentioned preparation is completed
Afterwards, you can carry out the measurement that fish in plane swims resistance, the reading and strain gauge 6 and lightweight aluminium chassis 4 of three strain gauges 6 are write down
Line deviation angle planar, is obtained the trip resistance of the fish in plane in conjunction with vector calculus.
By above-mentioned description, those skilled in the art completely can be without departing from this utility model technological thought
In the range of, carry out various change and change all within protection domain of the present utility model.Of the present utility model most
Matters, belong to the common knowledge of those skilled in the art.
