Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, embodiment of the present invention is made below further
Ground detailed description.
Embodiment 1
In order to realize that quick, easy target, the embodiment of the present invention devise a kind of measure for the husky turbulent flow of water and provide implementation
The device of environment, main body include: bracket 1, sampling apparatus 2 and stirring pool 3.
Wherein, guide rail 4, motor 5 and its driver 6, the shaft and crank rocker device 7 of motor 5 are placed in the top of bracket 1
Crank section be fixedly connected；The main rod end of crank rocker device 7 is connected with grid fixed plate 8.Specific effect can be detailed in Fig. 2.
When specific implementation, grid sets 9 are deep into stirring pool 3, and the shifting of grid sets 9 can be adjusted in real time according to testing result
Dynamic speed, reduces the movement speed of grid sets 9 when turbulent flow is too fast, grid sets 9 are accelerated when having sediment siltation in the bottom of stirring pool 3
Movement speed；The bottom opening of stirring pool 3；Sampling apparatus 2 is placed on the top of stirring pool 3 when using, for detecting stirring knot
The length of fruit, the crank section that motor 5 is connected with crank rocker device 7 is adjustable.
When specific implementation, crank rocker device 7 is made of crank and rocking bar two parts, and rocking bar is in when moving to left and right pole
Horizontality.
Further, guide rail 4 is matched with sliding block 10, and integrated model is preferably HGH30CA, and sliding block 10, which is placed in, leads
One-dimensional free movement can be carried out on rail 4.The both sides of guide rail 4 are fixed by screw with bracket 1.
Further, the model that motor 5 is selected is the model DM542 of 57BYG113-360A, driver 6.
Further, grid fixed plate 8 is made of upper stationary plane and a series of baffles vertical with upper stationary plane, upper fixation
Face is fixed by screw and sliding block 10, and baffle is fixedly connected with grid sets 9 using screw, and grid sets 9 can be removed, be replaced.
Further, the material of grid sets 9 is preferably aluminium alloy, and thickness is adjusted according to the actual needs of oneself, and hole is in grid
It is evenly distributed in lattice group 9, hole it is conveniently of circular shape, the area accounting in hole is 60 or so percent, specific every grid
Fig. 3 is shown in design.
Further, the material of stirring pool 3 is transparent acrylic material, bottom opening.
Further, it to be sampled respectively at the center of stirring pool 3 and four corners when sampling apparatus 2 uses.
In the husky turbulent flow metering preparation device of entire water, bracket 1 plays the role of fixed other devices.After stirring starts
Stirring pool 3 can shake under the impact of water flow inside, in addition can there is a situation where pool walls to rupture, therefore using bracket 1 will
Stirring pool 3 be fixed up be very it is necessary to.Bracket 1 can also provide fixed platform for motor 5 and guide rail 4 simultaneously, make
The relative position of whole device is fixed.
The rotation of motor 5 is converted the translation for horizontal direction by crank rocker device 7 and the cooperation of guide rail slide unit.In electricity
Machine 5 imparts the component of rocking bar horizontal movement during driving crank rotation, and constrains vertical direction by guide rail slide unit
Freedom degree, retention level direction freedom degree, thus by motor 5 rotation conversion in order to horizontal direction translation.
Wherein, grid sets 9 will be 60 or so percent as the area accounting in its hole of element of stirring silt water, this
Sample can guarantee silt aqueous mixtures stir evenly under the premise of, and will not make silt aqueous mixtures periphery of inner wall formed compared with
Big vortex causes big influence to sampling and experimental result.Due to being fixed by screw between grid sets 9 and grid fixed plate 8
Connection, when the accounting of silt in the mixture changes, the quantity of adjustable grid sets 9, changes the power of stirring, avoids out
Existing sediment siltation is in the bottom of stirring pool 3.
Embodiment 2
Below with reference to Fig. 1-Fig. 3, and specific calculation formula further introduces the scheme in embodiment 1,
It is described below:
Driving motor 5 rotates first when use, and the rotation of motor 5 can be converted into level by crank connecting rod apparatus 7 and guide rail 4
The connecting-rod head of the movement in direction, crank connecting rod apparatus 7 is connected with grid fixed plate 8, and grid fixed plate 8 is fixed on sliding block 10,
The simple harmonic motion in horizontal direction is done under the drive of crank connecting rod apparatus 7, the grid sets 9 being immersed in water at this time can in water
It swings back and forth to come water agitation.
Grid sets 9 will be moved in the form of SIN function in the horizontal direction:
L=Asin (f2 π t) (1)
In formula, A is that amplitude (cm) is related with crank length, and f is that vibration frequency (Hz) is related with motor rotation frequency, and t is
Time (s), L are grid positions (cm).
By formula it can be seen that after mechanical condition determines, the movement of grid is only related with vibration frequency, this is by motor
Rotational frequency determine.Therefore, the movement of grid sets 9 can be changed by adjusting the rotation of motor.
Due to being tightly connected between grid sets 9 and grid fixed plate 8, do not need to place under normal circumstances complete
The grid sets 9 in portion, when need to stir the accounting of silt in the mixture it is excessive when, the quantity of grid sets 9 can be increased to improve
The power of stirring avoids the occurrence of sediment siltation in the bottom of stirring pool 3, causes to stir non-uniform situation, simultaneously because grid
There are a large amount of holes can make grid sets 9 again can be to avoid the appearance of vortex while providing stirring power in group 9.
When range estimation uses the sampling drying at four corners of stirring pool 3 and center respectively of sampling apparatus 2 after mixing evenly
Weighing, weighing results are recorded and are handled, stirred evenly, and can carry out the operation of the experiment of the husky turbulent flow metering of corresponding water.
After the completion of the experimental implementation of the husky turbulent flow metering of all water, the piston (not shown) for opening bottom can will be stirred
Mix silt aqueous mixtures discharge useless in pond 3.It is clean for mixture to be discharged, it can star grid sets 9 to mixture
It is stirred.
The embodiment of the present invention to the model of each device in addition to doing specified otherwise, the model of other devices with no restrictions,
As long as the device of above-mentioned function can be completed.
It will be appreciated by those skilled in the art that attached drawing is the schematic diagram of a preferred embodiment, the embodiments of the present invention
Serial number is for illustration only, does not represent the advantages or disadvantages of the embodiments.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
