Embodiment
As shown in Figure 1, Figure 2 and a kind of simple to operate, the measurement result shown in Fig. 3 being that the utility model provides accurately for the Simple measurement device of underwater topography under complicated flow condition, and the method for operating that the Simple measurement device described in adopting is measured the underwater topography in above-mentioned situation.Described Simple measurement device comprises falling body 1, driving mechanism 2 and measuring mechanism 3, and described driving mechanism 2 is fixedly connected with described falling body 1 respectively with the lower end of described measuring mechanism 3; In measuring process, described falling body 1 is moved along needing the underwater topography 7 measured by described driving mechanism 2, and the underwater topography situation of different parts is measured by described measuring mechanism 3.And in order to simplify the structure of described Simple measurement device, facilitate the measurement of production scene to operate, realize real summary, described driving mechanism 2 is a soft pulling rope, and the lower end of described soft pulling rope is fixedly connected with described falling body 1; Described measuring mechanism 3 is the fine wire of a quality softness or is the thin tree lace of a quality softness or is the thin nylon rope of a quality softness, and the lower end of described fine wire or thin tree lace or thin nylon rope is fixedly connected with described falling body 1; Described falling body 1 is steel ball or the shot that a weight is not less than 1.5 pounds, described steel ball or shot are provided with two connecting holes 4, and described driving mechanism 2 is fixedly connected with described steel ball or shot respectively by described two connecting holes 4 with the lower end of described measuring mechanism 3; And in order to improve the security of measurement operation, described Simple measurement device also comprises support frame 6, described support frame 6 is fixed on the bank base 8 beyond underwater topography 7 along needing the bearing of trend of the underwater topography 7 measured, and described in the upper end edge of described driving mechanism 2 and described measuring mechanism 3, support frame 6 length direction is movably connected on described support frame 6.And the falling body 1 in order to avoid being done to make by steel ball or shot, in the drawing process measured, there is rolling and accuracy that impact is measured, the reverse direction of described steel ball or shot movement is also provided with the anti-rolling steel framework 5 be fixed on described steel ball or shot.
Due to the Simple measurement device having said structure, like this, when concrete measurement operates, just operation can be entered according to the step of lower step, first make the Simple measurement device containing support frame 6, steel ball or shot, driving mechanism 2 and measuring mechanism 3, and measure the entire length determining described measuring mechanism 3; Then described support frame 6 is fixed on the bank base 8 beyond described underwater topography 7 along needing the bearing of trend of the underwater topography 7 measured; Then be connected on described support frame 6 by the movable upper end of described driving mechanism 2 and described measuring mechanism 3, the lower end of described driving mechanism 2 and described measuring mechanism 3 is fixedly connected on described steel ball or shot; Subsequently described steel ball or shot being thrown in water, pulling described steel ball or shot by described driving mechanism 2 along needing the bearing of trend of the underwater topography 7 measured; Then stop according to designing requirement respectively and hold described driving mechanism 2 needing to measure each particular location of underwater topography 7, by externally measured chi measure described measuring mechanism 3 surface part length, eventually pass simple computation and draw result of calculation figure, completing once the surveying work of described underwater topography.During owing to adopting described Simple measurement device to measure underwater topography, the falling body 1 used is steel ball or shot, and in the whole process surveying reason, all use same described steel ball or shot, and driving mechanism 2 and measuring mechanism 3 are set respectively on described steel ball or shot realize falling body 1 respectively and pull and the function of linear measure longimetry under water, then through simply calculating and draw the surveying work that result of calculation figure finally completes described underwater topography, thus make measurement operation become very simple, make the result of measurement comparatively accurate.
Except the upper Simple measurement device adopting said structure, structurally to ensure to measure outside the security of operation and the accuracy of measurement result as far as possible, when adopting above-mentioned measuring method to measure, also have following some should be noted that, to ensure the accuracy of the security that measurement operates and measurement result to greatest extent, namely, when being pulled described steel ball or shot by described driving mechanism 2, be pull along the direction of water (flow) direction from downstream toward upstream; Stop and holding described driving mechanism 2 by externally measured chi measure described measuring mechanism 3 surface part length time, at least respectively measure a point at each concrete near sites determined along front and back, then average as the measured value of this measurement point position; Measure described measuring mechanism 3 surface part length time, the measuring mechanism 3 described in tension, makes described measuring mechanism 3 keep linear state to measure at water surface boundary 9 again.
The another one restitution adopting the Simple measurement device described in the application comparatively accurate and safe is because being, it is thicker that the driving mechanism of the Simple measurement device of the application's structure is a soft pulling rope, being connected on support frame 6 of movable upper end, thus ensure that soft pulling rope can not be broken or slip out of the hand in the drawing process of steel ball or shot; The thin nylon rope that the measuring mechanism of the Simple measurement device of the application's structure is the fine wire of a quality softness or the thin tree lace of quality softness or quality softness is superfine, upper end identical movement be connected on support frame 6, thus ensure that measuring mechanism is comparatively large at flow velocity, current are disorderly, and to strive resistance in fast current less, stretching when being convenient to measure, to ensure the accuracy measured.
