Description
Technical field
The utility model relates to a kind of ratio of in the echo bathymetric survey device difference of sonic echo depth finder being corrected and surveys device.
Background technology
It is an extremely important job that the device difference of sonic echo depth finder is corrected in bathymetric survey work, 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
The purpose of this utility model proposes a kind of novel bathymetric survey comparator, and this bathymetric survey comparator cooperates sonic echo depth finder to use, and can effectively overcome above-mentioned various comparators and than the existing weak point of survey method.
The bathymetric survey comparator that the utility model is designed, comprise 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 using method of this bathymetric survey comparator is as follows:
Earlier install sonic echo depth finder and transducer by the requirement that sounds the depth of the water, then the echo interception sheet metal of this 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 depth survey rope of bathymetric survey comparator, 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 the indicated degree of depth of its register or display panel and comparator are tackled reaches consistent and is stable, promptly finishes the ratio of sonic echo depth finder is surveyed correction.
Be used with this bathymetric survey comparator and sonic echo depth finder, can make things convenient for exactly the device difference of sonic echo depth finder is corrected, promptly, make it to reach the actual water depth information that accurately measures this district by adjusting the velocity of sound of sonic echo depth finder.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 this bathymetric survey comparator to carry out, than other comparator and better than survey method than survey.
Description of drawings
Fig. 1 is the structural representation of bathymetric survey comparator embodiment
Embodiment
Be described in further detail below in conjunction with the CONSTRUCTED SPECIFICATION of accompanying drawing the utility model embodiment:
Embodiment
As shown in Figure 1, the structure of this bathymetric survey comparator comprises: depth survey rope 1, echo interception sheet metal 2 and weight 3, depth survey rope 1 length has 30m, rope is marked with the length scale mark, echo interception sheet metal 2 is the circular slab of diameter 40cm, drawing by three isometric stay cords 4 in the lower end of depth survey rope 1 is echo interception sheet metal 2, the lower end of these three stay cords 4 is respectively to be connected on three end points that the circumference one that is positioned at echo interception sheet metal 2 connects equilateral triangle, make echo interception sheet metal 2 be in the horizontal equilibrium state, evenly have a plurality of permeable holes 6 on the echo interception sheet metal 2, one of them permeable hole is positioned at center of gravity (being the center of circle of the plate) position of this plate, weight 3 draws the below that is suspended on echo interception sheet metal 2 by a center tether 7 and three isometric tether 5 equilibrium systems, wherein, center tether 7 passes echo interception sheet metal 2 centers of gravity (being the center of circle of the plate) permeable hole of position and is connected the lower end of depth survey rope, article three, the upper end of isometric tether 5 is respectively that to be connected on echo interception sheet metal 2 bottoms be that to draw position, the weight of weight 3 be 20kg corresponding to three stay cords 4 on the plate.
