Description
Technical field
The utility model relates to a kind of land surveying gradiometer, belongs to surveying instrument technical field.
Background technology
In land surveying, measure the gradient fast and accurately, effectively can save the activity duration, alleviate the manual labor of mapping worker.The instrument of current measurement grade of side slope is a lot, especially coarse measurement grade of side slope, can select comparatively simple instrument or hand computation.
In existing, the slope requirement of most of side slope is coarse, but the gradient on road surface is less, require accurately, mostly be difficult to measure, especially through the road surface of bridge, the gradient is little, and road surfaces is often with some radians, therefore, general gradiometer is all difficult to reach measurement requirement, and measurement data detects by an unaided eye, accuracy is low, cannot tackle the slope measuring of region, a certain road surface with microradian.
Utility model content
The purpose of this utility model is to provide a kind of in land surveying, measure the gradiometer of the gradient rapidly and accurately, there is structure simple, easy to operate, highly sensitive, the advantage such as to be convenient for carrying, to reduce work difficulty during mapping worker operation outside, also mitigate the manual labor of staff simultaneously.
For achieving the above object, the utility model is achieved through the following technical solutions:
Land surveying gradiometer described in the utility model, comprise dial plate, dial plate is provided with bank pointer, horizonal base plate to be fixedly connected base by spring, base is provided with leveling bolt, leveling bolt connects horizonal base plate through the internal cavities of spring, base upper surface is provided with circular horizontal meter, free air temperature gauge and compass, be fixedly connected above base gauge dial bracket, gauge dial bracket is fixedly connected dial plate, the bottom of dial plate is provided with stopwatch and height indicator, and dial plate top is provided with gradient scale mark, indicates value of slope inside gradient scale mark.When carrying out land surveying operation, the compass on gradiometer helps operating personnel to take one's bearings, the sea level elevation that height indicator display is local, and the temperature of free air temperature gauge record locality is simple to operate, convenient and practical.
The center of bank pointer is fixed on needle pivot, and bank pointer top is set to hollow, and bank pointer bottom is set to solid.The center of gravity of such bank pointer is in bank pointer bottom, and bank pointer, all the time perpendicular to surface level, improves the sensitivity of gradiometer, more accurate during the measurement gradient.
Leveling bolt quantity is 3 ~ 4, and leveling bolt is identical with the quantity of spring.
The utility model compared with prior art, has following beneficial effect:
The utility model structure is simple, easy to operate, highly sensitive, the advantage such as to be convenient for carrying, to reduce work difficulty during mapping worker operation outside, also mitigate the manual labor of staff simultaneously.
Accompanying drawing explanation
Fig. 1, the utility model one embodiment front-view schematic diagram;
Fig. 2, the utility model one embodiment schematic top plan view.
In figure: 1, needle pivot, 2, stopwatch, 3, leveling bolt, 4, gradient scale mark, 5, dial plate, 6, bank pointer, 7, height indicator, 8, gauge dial bracket, 9, base, 10, horizonal base plate, 11, spring, 12, circular horizontal meter, 13, free air temperature gauge, 14, compass.
Embodiment
Below in conjunction with embodiment, the utility model is further described.
As shown in the figure, a kind of land surveying gradiometer described in the utility model, comprise dial plate 5, dial plate 5 is provided with bank pointer 6, horizonal base plate 10 to be fixedly connected base 9 by spring 11, base 9 is provided with leveling bolt 3, leveling bolt 3 connects horizonal base plate 10 through the internal cavities of spring 11, base 9 upper surface is provided with circular horizontal meter 12, free air temperature gauge 13 and compass 14, be fixedly connected above base 9 gauge dial bracket 8, gauge dial bracket 8 is fixedly connected dial plate 5, the bottom of dial plate 5 is provided with stopwatch 2 and height indicator 7, dial plate 5 top is provided with gradient scale mark 4, value of slope is indicated inside gradient scale mark 4, the center of bank pointer 6 is fixed on needle pivot 1, bank pointer 6 top is set to hollow, bank pointer 6 bottom is set to solid, leveling bolt 3 quantity is 3 ~ 4, leveling bolt 3 is identical with the quantity of spring 11.
When using gradiometer to carry out land surveying, first gradiometer is put in the horizontal plane, circular horizontal meter 12 bubble is made to be positioned at center by regulating leveling bolt 3, then gradiometer is placed on slope to be measured along the gradient, scale indicated by bank pointer 6 is ramp slope to be measured, the sea level elevation in this place can be observed out by height indicator 7 simultaneously, taken one's bearings easily by compass 14, free air temperature gauge 13 shows temperature at that time, the human oriented design of gradiometer is fitted reality more, convenient and practical, be more suitable for promoting the use of.
In sum, the utility model structure is simple, easy to operate, highly sensitive, the advantage such as to be convenient for carrying, to reduce work difficulty during mapping worker operation outside, also mitigate the manual labor of staff simultaneously.
