Firstly, each section telescopic bar by depth measurement bar body 1 is fully extended when measurement, in the section part for requiring flow measurement, will survey
Deep bar body 1 tilts into the water, until the level tray 5 of 1 bottom end of depth measurement bar body arrives at point position, tilt rotation depth measurement
The obliquity is kept after bar body 1, reads the length scale value L being located at the water surface in depth measurement bar body 1 at this time, i.e. Sounding Rod
Ontology 1 submerges the length in water；Apex angles instrument 2 and levelling by level meter is adjusted later, reads depth measurement bar body 1 at this time
Angle degree α between the 21 place straight line of flat-top of axis, i.e. Sounding Rod axial direction graduation mark 4 and apex angles instrument 2, apex angles
The 21 place straight line of flat-top of instrument 2 is parallel with horizontal plane 7 or is overlapped；Followed by, which is detected according to the angle degree α of reading
Corresponding sine function sin α.
Last basisIt is found that depth of water h=sin α L.
In measurement process, angle α is preferably adjusted to 30 °, the corresponding SIN function of angle α is 0.5 at this time, i.e. the depth of water is
Depth measurement bar body 1 enters the half of water length, can be quickly obtained accurate depth of water h without tabling look-up.
It can be seen that depth measurement rod structure of the invention is simple, using the telescopic structure of intussusception, it is not only convenient for carrying, and
And length is adjustable, suitable for the water-depth measurement of a variety of depth, while also ensuring that depth measurement bar body is not easy to be rolled over when deep water measures
It is disconnected, be conducive to improve measurement accuracy.The present invention utilizes the definition of SIN function simultaneously, by being arranged at Sounding Rod bodies top angle
Degree instrument accurately measures the axis of depth measurement bar body and the angle of horizontal plane, and finds out SIN function, then by the SIN function with
The water length that enters of depth measurement bar body can be obtained the accurate measurements of the depth of water as product, and it is lesser to solve measurement water surface width
When river, the problem that can not be paddled, the measurement process of the entire depth of water need to only be completed on the coast, easy to operate, and be not necessarily to
The person is paddled, and measurement accuracy and safety coefficient are improved, and practicability is extremely strong.

As shown in figure 3, the present embodiment provides a kind of measurement method based on Sounding Rod described in embodiment one, the Sounding Rod
Structure and working principle be discussed in detail in example 1, details are not described herein.Measurement method mainly includes as follows
Step:
Step 1: each section telescopic bar of depth measurement bar body 1 is fully extended, in the section part for requiring flow measurement, by Sounding Rod
Ontology 1 tilts into the water, until the level tray 5 of 1 bottom end of depth measurement bar body arrives at point position, tilt rotation Sounding Rod sheet
The obliquity is kept after body 1, reads the length scale value L being located at the water surface in depth measurement bar body 1 at this time, i.e. depth measurement bar body
1 submerges the length in water；
Step 2: adjustment apex angles instrument 2 is simultaneously levelling by level meter, reads the axis of depth measurement bar body 1 at this time, that is, surveys
Angle degree α between deep bar axial direction graduation mark 4 and the 21 place straight line of flat-top of apex angles instrument 2, wherein apex angles instrument 2
21 place straight line of flat-top is parallel with horizontal plane 7 or is overlapped；
