Description
Technical field
The utility model is related to Hydraulic Engineering Survey equipment more particularly to a kind of current speed measuring devices.
Background technology
Flow velocity refer to gas or liquid flow particle within the unit interval by distance.Current in channel and river are each
The flow velocity of point is different, and the flow velocity at river (canal) bottom, river bank is smaller, and the flow velocity at the heart approximately level of korneforos is maximum, is
It calculates easy, the speed of the section current is usually represented with cross section mean flow rate.During construction of hydro project, example
If bridge construction is required to measure the flow velocity in local waters, so as to design the impact resistance of bridge.
Existing flow velocity measurement is generally based on electronic chip calculating, and this kind of instrument cost is higher, and to the waterproof of instrument
It is more demanding.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of current speed measuring device, and the apparatus structure is simple, operation side
Just, it is and relatively low to waterproof requirement.
The utility model solves above-mentioned technical problem by following technological means：
A kind of current speed measuring device, including first baffle, second baffle and connection first baffle, the horizontal stroke of second baffle
Beam, the first baffle, the spacing of second baffle are known fixed range, are connected between the first baffle, second baffle
There is a guide rail, a float is movably installed on the guide rail, collision block is fixed on the float；The collision block is using magnetic material
Material is made, and the second baffle is equipped with electromagnet, timer and control switch, and the electromagnet, timer are by control
Switch control, the first baffle are equipped with the travel switch that control timer terminates timing, and the float makes with current movement
Obtain collision block impact stroke switch.
As being further improved for this programme, level meter is installed on the crossbeam.
As being further improved for this programme, the first baffle, second baffle bottom are both provided with inserted link.
As being further improved for this programme, the float is provided with through hole, and passes through the through hole on guide rail.
As being further improved for this programme, the diameter of the through hole is far longer than the diameter of guide rail.
The beneficial effects of the utility model：This programme uses the guide rail of known length as measuring route, by current band
Dynamic float drift hits the travel switch of timer, so as to measure the time that float moves in fixed range, further according to distance
With the calculated relationship of time, so as to calculate water velocity, while the electronic equipments such as timer are mounted on crossbeam, so as to save
Waterproof is gone, whole device is and simple to operate without waterproof.

2 bottom of plate is both provided with inserted link 9；The float 4 is provided with through hole, and passes through the through hole on guide rail L；The through hole
Diameter is far longer than the diameter of guide rail L.
Operation principle explanation：When being measured using the present apparatus, second baffle is inserted in upstream, first baffle is inserted in down
Trip, makes buoys float in the water surface, and keeps guide rail horizontal by level meter, presses control switch, electromagnet power-off timing simultaneously
Device starts timing, and float drifts about so that collision block impact stroke switch, timing terminates, so as to calculate water velocity.
Above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to preferred embodiment pair
The utility model is described in detail, it will be understood by those of ordinary skill in the art that, it can be to the technology of the utility model
Scheme is modified or replaced equivalently, and without departing from the objective and scope of technical solutions of the utility model, should all be covered
Among the right of the utility model.
