Abstract
Things, such as a flagpole, a tower top, a high building, etc., are required to be measured in real life. The utility model provides a laser altimeter. When the height of a measured object is measured, the laser altimeter is placed on a horizontal ground surface which is away from the measured object in a certain distance; a power supply of a number 1 laser pen is switched on, a red laser spot is aligned to the vertex of the measured object by adjusting a rotating shaft; the degree on a degree meter can be read when the red laser spot can be observed on the vertex of the measured object, and the degree is the degree of an angle a1; a power supply of a number 2 laser pen is switched on then, and the degree which can be read with the same method is the degree of an angle a2; a datum which can be calculated according to a formula of computation h (height) = tg a1*tg a2/tg a1-tg a2 (meter) is the height of the measured object. The utility model can be implemented conveniently.
Description
One, technical field
The utility model relates to a kind of laser ceilometer, relates in particular to a kind ofly can measure the very laser ceilometer of high object height fast.
Two, background technology
In the actual life, need measure the very height of high object, for example: cloud-kissing flagpole, cat head, high building etc., they are unattainable, have no idea to measure with conventional method, as use surveying instrument with the sight check and correction after mathematical computations again, then very loaded down with trivial details, workload is very big, and the error of sight is also big.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of laser ceilometer is provided, when measuring the height of testee 4, apparatus subject plate 1 is placed on the level ground 3 of testee 4 certain distances, very high as testee 4, then this distance wants far away, otherwise can be closely.Open the power supply of No. 1 laser pen 7, regulate rotating shaft 2, make red laser point aim at measured object summit 5, in the time of seeing red laser point on measured object summit 5, read the number of degrees of top number of degrees table, these number of degrees are exactly the number of degrees of angle a1.Open the power supply of No. 2 laser pens 8 again, regulate rotating shaft, make red laser point aim at measured object summit 5, in the time of seeing red laser point on measured object summit 5, read the number of degrees of number of degrees table 6, these number of degrees are exactly the number of degrees of angle a2.Then by computing formula h (highly)=tga1 * tga2/tga1-tga2 (rice).The data unit that draws is a rice, is exactly the height of the object of surveying.
Four, description of drawings
Below in conjunction with drawings and Examples, further specify the structure and the characteristics of the utility model laser ceilometer, in the accompanying drawing:
Fig. 1 is the structural drawing of embodiment one of the present utility model.
As shown in Figure 1, in embodiment one of the present utility model, comprise apparatus subject plate 1, rotating shaft 2, number of degrees table 6,7, No. 2 laser pens 8 of No. 1 laser pen, it is characterized in that No. 1 laser pen 7 and No. 2 laser pens 8 are installed on the apparatus subject plate 1, distance between them is 1 meter, rotating shaft 2 is installed on the apparatus subject plate 1, and laser pen 7 is fixed on the axle center of rotating shaft 2, indicates number of degrees table 6 in the upper right side of No. 1 laser pen 7 and No. 2 laser pens 8.
According to the laser ceilometer that the utility model provides, it is characterized in that described apparatus subject plate 1 can make of various nonmetal or metal materials.No. 1 laser pen 7 and No. 2 laser pens 8 can be with the laser pens of any model that can send red laser point.Rotating shaft 2 can be with the bearing and the axle center of various models and specification.
Five, embodiment
Implement laser ceilometer of the present utility model, can be used to measure the very height of high object such as flagpole, cat head, high building, because the light beam of laser is concentrated and penetrate farly, if the top of object is invisible to the naked eye, can be by telescope.Can also be with a counter programmed tga1 * tga2/tga1-tga2, writing on the apparatus subject plate 1 behind the pairing data lookup table of the different number of degrees of tga1 and tga2, like this when measuring, read the number of degrees and just found corresponding data, data input counter has just been obtained the height of object.Implement the utility model easily, very practical, effect is fine.
Claims (4)
1, a kind of laser ceilometer, comprise apparatus subject plate (1), rotating shaft (2), number of degrees table (6), No. 1 laser pen (7), No. 2 laser pens (8), it is characterized in that No. 1 laser pen (7) and No. 2 laser pens (8) are installed on the apparatus subject plate (1), distance between them is 1 meter, rotating shaft (2) is installed on the apparatus subject plate (1), laser pen (7) is fixed on the axle center of rotating shaft (2), indicates number of degrees table (6) in the upper right side of No. 1 laser pen (7) and No. 2 laser pens (8).
