Further, it is provided with retainer ring in the support arm front of motor.
The utility model has the advantages that, carry out, similar to Yangtze River Gorges section water-depth measurement, overcoming using single beam echosounding instrument
Existing use wave beam sounding instrument is carried out similar to the low problem of Yangtze River Gorges section water-depth measurement precision.
Existing single beam echosounding instrument measures value method, is after single beam echosounding instrument is surveyed and sends test signal, to incite somebody to action
The echo signal values for receiving at first are used as the water depth value for measuring（See D1 points pointed location in Fig. 1, what Fig. 1 was formed is using existing
There is the image that method is formed）, this is also that the deep method of water intaking is generally acknowledged in depth measurement industry, sees Harbin Engineering University's Y1436571 engineerings
Master thesis " double frequency digital sounding instrument signal transacting design of hardware and software and realization " paper, I also has been used up this side at unit
Method is operated, but its precision has problem always, later by compare repeatedly find its precision be mainly by the Yangtze River Gorges
The influence of topography, original value method at first is changed to the most intensity values method described in this patent, i.e., is sent out by single beam echosounding instrument by us
After going out depth measurement signal, most strong echo signal values as the water depth value of measurement will be received（See D2 points pointed location, Fig. 2 shapes in Fig. 2
Into be using this patent method formed image）.
Simultaneously also in the Xiling Gorge Dou Shantuo sections in the Yangtze River Gorges, contrast test is done, test method is that use can be produced
Field angle is that 1.5 degree of multibeam echosounders of transducer carry out a depth measurement, then it is 4 degree of lists of transducer that use can produce field angle
Wave beam sounding instrument（Existing method, is worth method at first）Method carries out a depth measurement, with production field angle is again afterwards 4 degree of transducers
Single beam echosounding instrument（This patent method, peak method）Method carries out a depth measurement, is compared afterwards, can produce field angle
For the result of 1.5 degree of multibeam echosounders of transducer is reference（Compared with traditional single beam echosounding, multibeam sounding system
Field angle it is smaller, depth measurement theoretical precision is higher.Test data shows, between narrow deep river course such as two dams, the section of reservoir area of Three Gorges valley,
To same river cross-section, the cross-sectional area of simple beam measurement is less than normal, system deviation nearly 5%）, concrete outcome is shown in Fig. 3（Have chosen it
In a section contrast schematic diagram）, hence it is evident that the method for this patent measures depth value and measures depth value more relative to existing method
Close to multibeam echosounder measurement result.
In narrow deep river course（As between two dams, reservoir area of Three Gorges valley section）, single beam echosounding data are using most strong echo-signal amount
When taking, close, the average deviation nearly 1% of the shape, area and multi-beam measurement of same section.
