Description
Technical field
The present invention relates to the technical field of bathymetric survey, particularly relate to a kind of method of in the echo bathymetric survey, the device difference of sonic echo depth finder being proofreaied and correct and special-purpose than surveying device.
Background technology
It is an extremely important job in bathymetric survey work that the device difference of sonic echo depth finder is proofreaied and correct, and it is a measure that improves and guarantee the bathymetric survey quality.
Carry out bathymetric survey in different pools (sea area) with sonic echo depth finder, all will be before operation begins and operation to carry out correcting device than survey after finishing poor; In same pool (sea area), sonic echo depth finder uses continuously, also to be no more than within 3 days, just must be poor with carrying out once correcting device than survey than the survey device, this is because the motor speed of sonic echo depth finder stability and gear train precision are also failed to reach long-time use and do not produced deviation.
At present, in bathymetric survey, the ratio survey device that the device difference of sonic echo depth finder is corrected has measuring staff comparator and water top comparator, employing measuring staff comparator comes: be subjected to the restriction of the length of measuring staff, can only survey with shallow work ratio 5m, be deeper than 5m and just be difficult to carry out, even can't carry out than survey than survey; Adopt water top comparator to carry out to be than the weak point of surveying: water-bed situation complexity, can't see the situation after the water top is put in the water, can't judge accurately whether the water top just is in the surface in seabed or enters the degree of depth in the earth.The method that also has the employing thermohaline to correct is carried out water deep correction, but adopt this method not only to need the thermohaline distribution data of this pool (sea area) during bathymetric survey, also need to carry out a large amount of interior industry arrangement correction work, not so, can't obtain this and distinguish the depth of water accurately.
Summary of the invention
Purpose of the present invention proposes a kind of new method that can proofread and correct the device difference of fathometer at the operation field of bathymetric survey, and for implementing the bathymetric survey comparator of the special use that this method designs, it is poor to cooperate sonic echo depth finder to use to proofread and correct fathometer with this bathymetric survey comparator, can effectively overcome above-mentioned various comparators and than the existing weak point of survey method.
Operation field fathometer difference correcting method proposed by the invention, its technical scheme is as follows:
Has echo interception sheet metal under the tether of length scale mark as the bathymetric survey comparator with a kind of by horizontally suspending one, be engaged in the device difference correction that operation field carries out sonic echo depth finder with fathometer and transducer thereof, its aligning step is as follows:
Earlier install sonic echo depth finder and transducer thereof by the requirement that sounds the depth of the water, then the echo interception sheet metal of described bathymetric survey comparator is successively put into several degree of depth of water, determine the accurate numerical value of each degree of depth by the length scale on the echo interception sheet metal tether, tackle the sound wave that transducer sends in each degree of depth by echo interception sheet metal, and by adjusting the velocity of sound of sonic echo depth finder, the degree of depth that makes the indicated degree of depth of its register or display panel and corresponding echo tackle sheet metal reaches consistent and is stable, promptly finishes the ratio of sonic echo depth finder is surveyed correction.
In the process of the velocity of sound of above-mentioned adjustment sonic echo depth finder, because the school zero line of its record may produce mobile, for guaranteeing the accuracy of the degree of depth that register or display panel are indicated, also need when adjusting the velocity of sound of sonic echo depth finder, adjust the record school zero line of fathometer simultaneously.Promptly adjust the velocity of sound on one side,, make it to keep stable Yi Bian adjust the school zero line.
For implementing the present invention better, the applicant has designed the bathymetric survey comparator of the special use that can be used with fathometer, its structure comprises the depth survey rope, echo interception sheet metal and weight, has the length scale mark on the said depth survey rope, the lower end of depth survey rope retracts sound interception sheet metal by at least 3 stay cord equilibrium systems, make echo interception sheet metal be in the horizontal equilibrium state, weight is drawn the below that is suspended on echo interception sheet metal by at least 3 tether equilibrium systems, the gravity of weight is concentrated on the center of gravity that acts on echo interception sheet metal, said echo interception sheet metal has enough areas, evenly have a plurality of permeable holes on the plate, one of them permeable hole is positioned at the centre of gravity place of echo interception sheet metal.
Said weight also can add again and is connected to a center tether, and the permeable hole that this center tether passes echo interception sheet metal centre of gravity place is connected the lower end of depth survey rope, to strengthen the stable and balance of comparator.
Said being shaped as of sheet metal of echo interception generally can be circle or regular polygon, preferably adopts circle, and the area of plate is with 700～3000cm
2Be advisable.
The approrpiate wts of said weight is 10～20kg.
Said depth survey rope can be decided according to investigation depth, and suitable length is 20～30m.
The present invention has following beneficial technical effects:
The present invention can conveniently proofread and correct the device difference of sonic echo depth finder exactly at the operation field of bathymetric survey, can pass through to adjust the velocity of sound of sonic echo depth finder at the operation field of bathymetric survey, makes it to reach the actual water depth information that accurately measures this district.Also can survey by ratio to the depth of water at all levels, understand the situation of measured zone water body, promptly whether there are temperature and halocline, needn't carry out a large amount of correction of depth work of temperature and salinity as before, like this, not only alleviated the housekeeping of interior industry, and can avoid because of numerous and diverse mistake that is easy to generate of working.Therefore, in bathymetric survey work, adopt the present invention that the device difference of sonic echo depth finder is proofreaied and correct, convenient, accurate, easy operating can overcome other in order to the comparator of correction fathometer difference with than the existing weak point of survey method.
