Embodiment
As shown in Figure 1, laser leveler of the present invention, it includes optical splitter, the light outlets of described laser leveler is located at by described optical splitter, described optical splitter includes multiple laser instrument 11 and motor 12, described motor 12 is provided with rotating shaft 13, and multiple described laser instrument 11 is located on the conglobate lasing light emitter of shape in described rotating shaft 13 uniformly, and the light that the light that described lasing light emitter sends sends with described laser leveler overlaps.Motor 12 drives circular lasing light emitter to rotate, and enables lasing light emitter send the lasing area of planar.
Wherein, the time that described motor 12 rotates a circle is less than most short reaction time of human eye.Because the most short reaction time of human eye is 1/24 second, therefore, the rotating speed of this preferred embodiment motor 12 is 24 turns per second, and it is the lasing area got that human eye cannot be differentiated, or the face that real laser is formed, visually forming surface light source.
As shown in Figure 1, described optical splitter also includes light-blocking structure 14, described light-blocking structure 14 is fixed on the light transmition direction of the described laser instrument of part, and the light making described light-blocking structure 14 can block section laser to send, enables described laser leveler send the lasing area of arc.Described light-blocking structure 14 is installed on described laser leveler body slidably, or described light-blocking structure 14 is fixed in the rotating shaft 13 of described motor 12 rotationally.The radian of the lasing area that the position changing described light-blocking structure 14 can regulate laser leveler to send, can also regulate the transmit direction of sub-horizontal light beam, is that left side is luminous or right side is luminous, the radian of the radian of left side light beam, right side light beam.
In the present embodiment, described light-blocking structure 14 includes positive baffle plate 15, two side shields 16 and two web joints 17, two described side shields 16 are fixedly connected on the both sides of described positive baffle plate 15, and two described web joints 17 are individually fixed in the upper and lower side of described positive baffle plate 15 and described side shield 16; One end of connecting link 18 is connected with the rotating shaft 13 of motor 12 is rotating, and the other end is connected with described web joint 17, and as shown in Figure 1, preferred described web joint 17 is arc near the side of described connecting link 18.Described light-blocking structure 14 can be placed on the periphery of described lasing light emitter, and can rotate around described lasing light emitter, preferred described light-blocking structure 14 can block the light of 180 degree that described lasing light emitter sends, namely user can rotate described light-blocking structure 14 as required, makes described light-blocking structure 14 can block the left side of described optical splitter 10 or the light of right side 0-180 degree.
In another embodiment, preferred described light-blocking structure 14 also can be curved baffle, the upper and lower side of described curved baffle is respectively in rotating rotating shaft 13 of being fixed on described motor 12, the radian of preferred described curved baffle 14 is 180 degree, make described curved baffle 14 can be blocked in the periphery of described lasing light emitter, thus the left side of described optical splitter 10 or the light of right side 0-180 degree can be blocked.
When installing electronic curtain, first, the position of combination determination steelframe is being installed, i.e. the position of height, width, up and down edge.
As shown in Figure 2, then, utilize high-precision digital-display altimeter 20, determine the altitude datum point A installing edge of combination, wherein, SD is oblique distance, and HD is horizontal range, and VD is vertical height, and INC is angle of inclination, and HT is absolute altitude.Utilize the method for high-precision digital-display altimeter measuring height reference point to belong to prior art, the present invention does not repeat them here.。
As shown in Figure 3, then, with height A point for reference point, described laser leveler 100 is utilized to determine the position of combination edge line AC, left hand edge vertical line AB on the whole.At this, because wall is arcwall face, therefore straight line AC is traditional horizontal line, instead of the actual water horizontal line on arc wall, now, as shown in Figure 4, needs the true arcwall face AC determined on radian wall
1, AC
2, AC
3etc. a series of datum line.Like this, along line segment AC
1, AC
2, AC
3deng the C on datum line
1, C
2, C
3connect into line Deng reference point, can determine that combination is at arcwall face upper horizontal line position (the horizontal line AC namely arcwall face being really).
As shown in Figure 5, utilize stadimeter to find range along pedal line AB, so just determine the position reference point of the lower limb of combination, utilize the above-mentioned actual position of method determination horizontal line BD on arc wall determining horizontal line AC.With A, B two reference points and straight line AC, BD, utilize high-precision digital-display stadimeter, thus determine C, D two reference points, now, reference point A, B, C, D of corner determine all, namely determine the precise mounting position of combination.Like this, even if combination is installed in segmentation, as long as four reference points are constant, whether every section of corner reference point using laser leveler to calibrate each sectionally smooth join wall before installing just can determine on straight line AC, BD whether each combination in batches installed has deviation at every turn.
The above embodiment only have expressed this several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to book patent of invention scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
