The effect of embodiment
Diving mixer impeller testboard longitudinal direction mechanism involved by the present embodiment, because the testboard is longitudinal
It includes sprocket wheel unit, the first lead screw unit and the second lead screw unit that mechanism, which has moving portion and measurement portion, moving portion, by the
Two lead screw units enable to measurement portion to be moved on vertical direction (directions z), are enabled to by the first lead screw unit
Second lead screw unit carries out mobile in the second horizontal direction (directions y) and then measurement portion is driven to be carried out in the second horizontal direction
It is mobile, enable to the first leading screw unit, the second lead screw unit and measurement portion in first level direction (x by sprocket wheel unit
Direction) it is moved, therefore measurement portion moving freely in three directions, Jin Erzhi can be realized as by entire moving portion
Connect the flow velocity measured on three dimensions different location so that the result of measurement is more accurate, and measurement efficiency significantly improves.This
Outside, entire testboard longitudinal direction mechanism structure is simple, significantly reduces measurement cost.
Further, sprocket wheel unit carries out driving by decelerating motor and carries out chain drive by chain kit, then
First movement component is driven to be moved on first level direction by driving mass block.Decelerating motor so that reduction of speed is same
Shi Tigao output torques and the inertia for reducing load, chain drive and the setting of mass block make total more adduction
Reason, so that first movement component can carry out the movement of relatively long distance under the impact of flow on first level direction,
And mobile process is highly stable.
Further, the setting of anti-off-axis is so that the movement of first movement component is limited in the first track and the second track
Groove in, and then the stability moved under water impact is improved, to improve the stability and reliability of measurement.
Further, the number of the constant gap of two movable plates, the second lead screw unit is two, and measurement portion includes two
Current meter, two current meters are mounted on by the second lead screw unit unit on two movable plates respectively, so current meter can be
It is spaced fixed different location and carries out flow velocity measurement.
Further, Hall switch and magnet enable to first movement component from one end of the first track and the second track
(initial end) returns to initial end immediately after moving to the other end (tail end), improves the operation effect of entire testboard longitudinal direction mechanism
Rate.
Further, control unit is the computer equipped with control program, therefore can be believed by driving by control unit
Number come control decelerating motor, the first stepper motor and the second stepper motor so that control sprocket wheel unit, the first lead screw unit with
And second lead screw unit movement to realize that the flow velocity on three dimensions different location measures, high degree of automation improves
Measurement efficiency, and save manpower consumption.
The above embodiment is the preferred case of the present invention, is not intended to limit protection scope of the present invention.
For example, in embodiment, the number of the second lead screw unit is two, and measurement portion includes two current meters, two flow velocitys
Instrument is installed on two movable plates, to be spaced fixed different location progress flow velocity measurement.But in the present invention, in order to
Measurement data as much as possible is obtained at the same time to improve the follow-up accuracy for calculating three-dimensional flow field figure, second
The number of bar unit can also be four, and measurement portion can also include four current meters, and two flow velocitys are installed on each movable plate
Instrument, the two current meters are separately positioned on the vertical position corresponding to the both ends of movable plate, so as to obtain first simultaneously
Position in horizontal direction, in the second horizontal direction and on vertical direction is all different but the flow velocity of alternate constant position.
In embodiment, support portion is supporting rack, come to moving portion in such a way that supporting rack is fixed on the cover board of pond
It is supported.But in the present invention, support portion can also be column, and column is fixed on bottom of pond, and setting fixed structure is used on column
Come to moving portion the first track and the second track be fixed, support.
