At this time, the lower body 311 has an opening (not shown in the figure) is opened so that the support 410 is inserted and rotated on the outer surface. In addition, the lower body 311 forms a lower coupling jaw (311a) spaced apart from each other on the bottom surface protrudes upward.

The gear handle 320 is rotatably formed between the upper body 312 and the lower body 311, and preferably further includes a handle 321 of the gear handle 320 protrudes outward.

In addition, the gear handle 320 is a toothed gear is formed on the inner surface is fixed to mesh with the sub-gear means 330. That is, when the handle 321 is drawn out and rotated, the gear handle 320 transmits the force to the sub gear means 330, and the rotational force of the sub gear means 330 is vertically up and down of the central gear means 340. It is transmitted by exercise power.

The sub gear means 330 is fixed in the upright direction about the center gear means 340, and the sub gear means 330 is linked to the rotation of the gear handle 320 to the center gear means 340. To power). The bearing gears 350 and 360 are pivotally installed on the upper body 312 and the lower body 311 at regular intervals from the sub-gear means 330 around the center gear means 340, and the bearing gears 350 and 360 are rotated. ) Functions to support the side surface so that the central gear means 340 can be rotated in the center of the upper body 312 and the lower body 311 without being pushed to one side by the sub-gear means 330.

At this time, the sub-gear means 330 is fixed to the bearing 334 provided on the bottom surface of the lower body 311 and the rear surface of the upper body 312 and fixed with a screw 335 fixed shaft 331, A drive worm gear 332 fixed at an outer surface of the fixed shaft 331 and engaged with the central gear means 340, and a pinion gear engaged with an inner surface of the gear handle 320 at an upper end of the fixed shaft 331; 333.

The fixed shaft 331 is fixed to the rear surface of the upper body 312, the lower side is fixed by a screw 335 on the bottom surface of the lower body 311.

The drive worm gear 332 is rotatably fixed at the fixed shaft 331 to be engaged with the central gear means 340 to transmit the rotational force transmitted from the pinion gear 333 to the central gear means 340.

The pinion gear 333 is rotatably fixed at the upper end of the fixed shaft 331 to be engaged with the inner surface of the gear handle 320. The pinion gear 333 is an integral type extending upward from the drive worm gear 332 to transmit the rotational force of the gear handle 320 to the drive worm gear 332.

The sub gear means 330 and the bearing gears 350 and 360 are fixed around the central gear means 340, respectively. However, the sub-gear means 330 transmits the rotational force of the gear handle 320 to the central gear means 340, and the other bearing gears 350 and 360 are interlocked as the center gear means 340 is rotated. And rotate.

The central gear means 340 is fixed so that the upper and lower sides are rotatable by the upper bearing 341 and the lower bearing 345 respectively fixed at the upper locking jaw 312a and the lower locking jaw 311a. A central rack 344, a driven rack gear 342 meshing with the drive worm gear 332 of the sub-gear means 330 above the central shaft 344, and a lower side of the driven rack gear 342 A circular rack gear 343 meshes with the half moon gear 413.

The upper bearing 341 and the lower bearing 345 are respectively fixed at the upper catching jaw 312a and the lower catching jaw 311a to fix the upper and lower ends of the fixed shaft 331 to be rotatable.

Here, the spaced spaces between the upper locking jaws 312a of the upper body 312 form an upper path 314 that serves as a passage through which the central axis 344 is raised, and the upper path 314. The spaces spaced apart between the lower engaging jaw 311a of the lower body 311 as a lower portion of the lower body 311 form a lower path 313 serving as a passage when the central axis 344 is downward.

The central shaft 344 is fixed by the upper bearing 341 and the lower bearing 345, respectively, and is moved up and down in accordance with the rotation direction of the drive worm gear 332. That is, since the central shaft 344 is engaged with each other when the driving worm gear 332 is rotated to the left side, for example, the driven rack gear 342 follows the upper path 314 according to the rotation of the driving worm gear 332. Is elevated through. On the contrary, the driving worm gear 332 is lowered through the lower path 313 by the force transmitted by being rotated in the opposite direction.

The circular rack gear 343 is integrally formed with the central shaft 344 and is formed to engage the vandal gear 413. Here, the circular rack gear 343 transmits a force to the half moon gear 413 as the central shaft 344 is moved up and down to rotate the support 410 in the vertical direction. Here, the thread of the circular rack gear 343 is formed in a horizontal direction, and the half moon gear 413 is engaged with the thread of the circular rack gear 343 in the horizontal direction in a vertical direction. Accordingly, the horizontally applied force transmitted by the circular rack gear 343 is converted vertically by the half moon gear 413 to rotate the support 410 in the vertical direction.

The driven rack gear 342 is formed integrally with the central shaft 344 on the upper side of the circular rack gear 343 and is formed to engage the drive worm gear 332. The driven rack gear 342 raises and lowers the central shaft 344 because the driven rack gear 342 is moved in one direction by the force transmitted by the driving worm gear 332.

The present invention includes the configuration as described above, in the following will be described in detail with reference to Figures 6 to 8 the effect achieved through the configuration as described above.

Referring to FIGS. 6 and 7, the worker first climbs to the rooftop of a neighboring building to install the light emitting light emitting device 10 and places the light emitting light emitting material 10 around the drain hole 500. And the operator rotates the gear handle 320 in one direction to manipulate the support 410 was gathered in the center to spread outward.

To explain this in detail, first, the operator pulls the handle 321 of the gear handle 320 from the outer surface of the gear handle 320 and then applies the force in one direction to rotate the gear handle 320.

Therefore, a force is transmitted to the pinion gear 333 of the sub gear means 330 engaged with the inner surface of the gear handle 320. As the drive worm gear 332 is integrally formed with the pinion gear 333, the driving worm gear 332 is rotated in the same direction simultaneously with the rotation of the pinion gear 333 to lower the driven rack gear 342 of the central gear means 340. Let's do it.

In this case, the driven rack gear 342 may be rotated along the driving worm gear 332, which is to prevent friction heat and wear from occurring between the driven rack gear 342 and the driving worm gear 332.

The center gear means 340 is lowered along the upper path 314 between the upper locking jaw (312a). In addition, since the circular rack gear 343 is descended while the driven rack gear 342 is rotated, the circular rack gear 343 simultaneously transmits a force to the half moon gear 413 that is lowered and engaged.

In this case, the half moon gear 413 is rotated by the force transmitted from the circular rack gear 343 to rotate the support 410 upward.

Therefore, when the supporter 410 is rotated and spread outward through the above process, the worker lifts the light emitting device and positions the upper portion of the drain hole 500. And the operator rotates the gear handle 320 to rotate the support 410 upwards. At this time, if the pressing rubber 431 of the locking foot 430 is in close contact with the inner surface of the drain hole 500, and the locking jaw 432 is caught on the upper end of the drain hole 500, the gear handle 320 The pressing rubber 431 strongly presses the inner surface of the drain hole 500 by the force transmitted through the half moon gear 413 by the manipulation. In addition, the catching foot 430 is rotated by the catching hinge 420 as the force is continuously transmitted, and the catching jaw 432 is rotated until the rotation is prevented by the coupler 414.

Therefore, the surface light emitter 10 according to the present invention is firmly fixed at the upper side of the drain port 500 by the crimping force of the pressing rubber 431 and the locking step 432 at the upper end of the drain port 500. Can be.

Thereafter, when the fixing operation of the light emitting device to the upper end of the drain hole 500 is completed, the operator manipulates the ball fixing handle 220 to adjust the horizontal degree of the light irradiator 110. At this time, the operator adjusts the direction of the ball 230 to maintain the horizontal through the horizontal system 120 so that the light irradiator 110 is fixed in a horizontal state.

Here, the light emitting device is connected to a separate control device to which the communication device for communication with the position coordinates and the aircraft (A) is added. Here, the control device is generally applied to a known device, and thus a detailed description thereof will be omitted. In addition, hereinafter, the aerial image photographing process using the aircraft (A) will be briefly described.

8 to 9, the aircraft A is equipped with an aerial photographing camera 20 that can collect photographed images of various directions and angles during one flight. At this time, a plurality of cameras dedicated to aerial photography are arranged at various angles, and the plurality of cameras arranged as described above may perform ground shooting in various directions at one point.

Preferably, the aerial photographing-only camera 20 may be enough to check and photograph the laser light of relatively low power emitted from the surface light emitter 10 even at a high altitude.

The surface light emitter 10 is installed at a specific point on the ground to irradiate the laser light toward the camera 20 installed in the aircraft A during aerial photography. The laser light irradiated from the surface light emitter 10 is irradiated at a low power within 1 to 20 W for safety, and the surface light emitter 10 is irradiated with a plurality of laser lights at once to increase the photographing probability of the camera 20. Controlled.

The surface light emitter 10 is designated through accurate positioning and verification, and the designated position is used as a ground reference point during geodetic surveying. In the present invention, to install the surface light emitter 10 on the roof of the building, but in order to reduce the occupancy of the space to install in the top of the drain port 500 can prevent the problem due to unauthorized possession in the private building, rooftop It is possible to install without limit of space even in narrow space by structure inside.

Therefore, the worker can arrange a large number in a specific area, such as downtown, and can use various ground control points in a complex urban area, thereby increasing the accuracy and reliability of geodetic surveying.

On the other hand, the surface light emitting device 10 may be connected to a power supply unit for supplying power, and a control device configured with various devices for irradiating laser light.

Accordingly, the surface light emitter 10 determines the irradiation of the laser light by checking the position with the aircraft A in the control device, and the light irradiator 110 is driven to output the laser light.

Therefore, the aerial image taken by the aircraft (A) is photographed by the laser light irradiated from the light emitting emitter 10 for the surface, and the laser light image thus captured can be confirmed through the position coordinates of the light emitting device for the pavement Therefore, the aerial image synthesis can be performed as the ground reference point.

When the aerial photographing work of the aircraft (A) is completed, the worker collects a plurality of surface emitting light l9 (10) installed in various places in the city. The operator grasps the handle 321 and rotates the gear handle 320 in a direction opposite to the direction in which it was first rotated by the pinion gear 333 and the driving worm gear 332. Raise (344). Then, as the half-gear gear 413 engaged with the circular rack gear 343 is rotated by the force transmitted by the central shaft 344, the support 410 is rotated inward, thereby supporting all the supports 410 at the center side. Are gathered.

And the operator is to be stored in the carrying case (not shown in the figure) to move in the state in which the support 410 is folded as described above.
