Description

Angle self-adaptation gradient measurer

Technical field

The utility model belongs to topographical surveying instrument field, specifically a kind of surface slope measuring instrument.

Background technology

The measurement of the gradient is the important means of obtaining topography and geomorphology information, ground inclination is engineering construction, agricultural production, soil erosion assessment and the important parameter of administering, utilize traditional total powerstation, transit that the gradient is measured, though precision is higher, but the instrument heaviness, complex operation, it is lower to measure efficient, and domatic measurement that can only be bigger to area, measurement result can't reflect domatic details.Though and it is more convenient to utilize measurement means such as compass, surveyor's staff to carry, measuring error is bigger, influenced by external environments such as magnetic field, humidity.

The utility model content

In order to overcome the deficiency of traditional slope measuring equipment and method, the utility model provides a kind of slope measuring instrument of inclined-plane, and this instrument can not only carry out slope measuring rapidly, but also have easy and simple to handle, can adapt to advantages such as various environment.

The purpose of this utility model is realized by following design: device mainly comprises fixed bar, circular bubble, connection bearing, 4 parts of measurement cross bar, and circular bubble is connected the top of fixed bar, and connection bearing is connected and fixed bar simultaneously and measures cross bar.When carrying out field survey, to measure cross bar is adjacent to be measured domatic, realize that by physical construction instrument is to the self-adaptation of surface slope, after circular bubble on the adjustment fixed bar makes fixed bar perpendicular to surface level, with fixed bar place straight line as hypotenuse, measure on the cross bar pointer place straight line as the right-angle triangle of right-angle side just and inclined-plane triangle formation similar triangles, according to similar triangle theory, the angle that surface slope just equals to measure cross bar place straight line and measures the pointer place straight line on the cross bar, the size of this angle can directly read out by the angle dial on the connection bearing.

Compared with prior art, the beneficial effects of the utility model are:

(1) simple in structure, dismounting, easy to carry.

(2) measure convenient and efficient, precision is reliable.Domatic angle self-adaptation, fixed bar is vertical after, the gradient has just shown at index dial, direct reading gets final product, error is less, a people gets final product complete operation.

(3) be subjected to external conditions such as magnetic field, weather to influence less.

(4) ninor feature can be adapted to, domatic detailed information can be recorded.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

As shown in Figure 1, angle self-adaptation gradient measurer mainly is made up of fixed bar (1), circular bubble (2), connection bearing (3), (4) four parts of measurement cross bar, circular bubble (2) is connected the top of fixed bar (1), and connection bearing (3) is connected and fixed bar (1) simultaneously and measures cross bar (4).

As shown in Figure 2, fixed bar (1) mainly is made up of cross bar and montant, and cross bar provides to be controlled, and montant guarantees vertical, and the montant lower end is taper, is convenient to insert soil.

As shown in Figure 3, a circular bubble (2) is fixed in fixed bar (1) middle and upper part, and the circular bubble plane is vertical with fixed bar, and when the circular bubble bubble was placed in the middle, fixed bar was vertical with level surface, for slope measuring provides benchmark.

As shown in Figure 4; connection bearing (3) is a hollow bushing; the sleeve pipe aperture is slightly larger than fixed bar; make connection bearing can be on fixed bar free movable; to guarantee measuring cross bar (4) energy close proximity to ground, sleeve pipe one side index dial (3b) maximum range is 90 degree, and index dial lower-left side has the high-frequency orientation protector (3a) of a projection; to guarantee that instrument is reported to the police automatically under the reverse situation of installation.

As shown in Figure 5, measuring cross bar (4) is the light aluminum alloy quality, length 120cm, and the top has a vertical pointer (4b) to be used to indicate reading, and cross bar links to each other with connection bearing by bolt (4a).

The principle of angle self-adaptation gradient measurer as shown in Figure 6, when carrying out field survey, to measure cross bar and be adjacent to ground, after being adjusted to fixed bar vertically with circular bubble, sounding rod place straight line a is parallel with the normal b of geoid surface, then can release ∠ β=∠ γ, ∠ α+∠ β=90 ° again, ∠ θ+∠ γ=90 °, then ground inclination angle θ equals the angle α that sounding rod pointer and fixed bar form, and measures the gradient size that angle α both can obtain the inclined-plane.

The use step of angle self-adaptation gradient measurer is: at first connection bearing and the measurement cross bar that links together placed on will measure domatic, then fixed bar is passed the sleeve pipe of connection bearing, insert domatic, adjust circular bubble, make the circular bubble bubble placed in the middle, measure that the indicated index dial number of degrees of pointer are the domatic gradient to be measured on the cross bar this moment.
