Description
Technical field
The utility model relates to a kind of auxiliary locators that current meter tests the speed.
Background technique
Current meter is the instrument for measuring flow velocity.Current meter measurement is common basic skills in discharge measurement.One
Under fixed condition, this method precision is higher, frequently as the standard for identifying other flow measurement methods.Currently, current meter on the market has electromagnetism
Current meter, acoustic Doppler velocimetry, outstanding paddle current meter etc..Wherein, current meter be more widely water conservancy hydrometric station,
The unit of the profession water conservancy hydrologic research flow rate such as environmental protection tests station, Experimental Study College and Bureau of Water Resources.
Although existing current meter measurement is accurate, simple using easy and maintenance, main to the test of water velocity
It is tested by manually current meter is held, current meter is unable to fixation measuring, can not accurately measure the flow velocity of different water depth, people
Work can not bear to hold for a long time, so cause measurement data inaccurate, and measurement work is caused to make troubles.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of raising measurement data accuracys, saving manpower
The auxiliary locator to test the speed with current meter easy to use.
To achieve the above object, the auxiliary locator that a kind of current meter provided by the utility model tests the speed, wherein including
The pulley table that is equipped on the water surface is equipped with the sliding block slid against in pulley table in pulley table, is equipped on sliding block to pulley table
The arc bracket of outer extension, arc bracket end be equipped with it is with a scale and can oscilaltion elevating lever, on elevating lever bottom end
Equipped with the supporting plate for placing current meter, and the position-limit mechanism limited to lifter rod lifting is equipped on arc bracket.
In some embodiments, position-limit mechanism includes in arc bracket end equipped with the body for being placed on elevating lever, and
Body is equipped with and penetrates the ejector pin that set withstands elevating lever in vivo in vitro from set.
In some embodiments, the circular hole for placing current meter is provided on supporting plate.
Measurement data accuracy is improved the utility model has the beneficial effects that having, saves manpower and effect easy to use
Fruit.Due to overcome in the prior art current meter be not capable of fixing, by man-hour manually hand-held, and cannot accurately measure the stream of different water depth
Speed causes measurement data inaccurate, and artificial laborious disadvantage has developed one kind and tested without manually holding current meter, and
And can be convenient by current meter fix and also can oscilaltion correspond to the different depth of water, to improve the water of measurement accuracy
Water speed fixed equipment is surveyed using current meter, causes measurement data is inaccurate to lack by manual testing's water speed in the prior art to overcome
Point.In application, sliding block can slidably reciprocate, row conveniently rides on the both sides boundary for the water surface to be measured, sliding block in pulley table
It is fixed on arc bracket, installation can sound the depth of the water with graduated elevating lever on arc bracket；The installation of elevating lever end
There is supporting plate, supporting plate has a circular hole, for putting current meter.When carrying out water conservancy measurement, current meter is placed on supporting plate, if mobile sliding block
To at different active cross-section, elevating lever is inserted into the bottom, data is write down, elevating lever is then being mentioned the water surface, is writing down data,
Two data differences are the depth of water, by calculating, can be calculated such as 0.2h, and the position of elevating lever, puts elevating lever when 0.6h, 0.8h
To corresponding position, current meter is run, so that it may the flow velocity of the section different water depth is measured, to obtain the flow velocity point of the section
Cloth.In this way, being tested without manually holding current meter, and the depth of water is also relatively more accurate, to easily be surveyed to flow velocity
Amount.It realizes and improves measurement data accuracy, save manpower and effect easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of auxiliary locator that current meter tests the speed, including be equipped on the water surface pulley table 1, in cunning
Luntai 1 be equipped with slide against sliding block 2 in pulley table 1, be equipped on sliding block 2 arc bracket 3 extended to outside pulley table 1,
3 end of arc bracket be equipped with it is with a scale and can oscilaltion elevating lever 4, be equipped on 4 bottom end of elevating lever and place current meter
Supporting plate 5, and be equipped on arc bracket 3 and the position-limit mechanism 6 limited is gone up and down to elevating lever 4.Position-limit mechanism 6 is included in arc
3 end of bracket is equipped with the body 61 for being placed on elevating lever 4, and is equipped with to penetrate to cover in vitro from set on body 61 and withstands elevating lever in vivo
4 ejector pin 62.The circular hole for placing current meter is provided on supporting plate 5.
In application, sliding block 2 can slidably reciprocate, row is in the both sides boundary in pulley table 1, conveniently riding over the water surface to be measured
On, sliding block 2 is fixed on arc bracket 3, and installation can sound the depth of the water with graduated elevating lever 4 on arc bracket 3；It rises
Drop 4 end of bar is equipped with supporting plate 5, and supporting plate 5 has a circular hole, for putting current meter.When carrying out water conservancy measurement, current meter is placed on support
On plate 5, if elevating lever 4 is inserted into the bottom, data is write down, then elevating lever by mobile sliding block 2 at different active cross-sections
4 mention the water surface, write down data, and two data differences are the depth of water, by calculating, can calculate such as 0.2h, and when 0.6h, 0.8h goes up and down
Elevating lever 4 is put into corresponding position, runs current meter by the position of bar 4, so that it may the flow velocity of the section different water depth is measured,
To obtain the velocity flow profile of the section.In this way, tested without manually holding current meter, and the depth of water is also relatively more accurate,
To easily be measured to flow velocity.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical new
The protection scope of type.
