Description

Technical Field

[0001] The invention relates to the technical field of measuring equipment, and in particular to a measuring equipment for space planning. Background Art

[0002] Aerial photogrammetry refers to the process of taking continuous images of the ground with aerial photographic instruments on an airplane, combining ground control point measurement, mapping and stereo mapping to draw a topographic map. Aerial photography is the use of airplanes or other aircraft (such as balloons, satellites and spacecraft, etc.) with special cameras mounted on them to photograph the ground to obtain photos. Aerial photography using airplanes is called aerial photography. The cost of using airplanes for aerial photography and measurement is relatively high. With the continuous development of drone technology, the use of drones for aerial photography and measurement can effectively reduce the measurement cost.

[0003] Most of the existing drones used for shooting use fixed connections when connected to the shooting and measuring components, which is not conducive to the rapid replacement of the shooting and measuring components and their maintenance. At the same time, after the drone hovers, it can only be adjusted slightly under the control of the adjustable gimbal, and cannot be adjusted over a large range. In order to solve the above technical problems, the patent document of the authorization announcement number CN116625321B discloses an aerial photogrammetry device and a measurement method, wherein, after flying to a specified position and hovering at a height, the staff can control the extension of the electric telescopic rod: when the electric telescopic rod is extended to make the wheel part and the ring part collide, the circular ring part can drive the connecting block to make the frame drive the shooting and measuring component to swing with the axis of the worm as the center of the circle; when the electric telescopic rod is contracted to make the wheel part and the contact plate part collide, the worm drives the worm wheel to rotate with the circular rod as the center of the circle to better align the shooting and measuring position; the photography of the shooting and measuring component can be driven to adjust at multiple angles, and the geographic information can be collected, photographed and measured through the photography of the shooting and measuring component. The aerial photogrammetry device has a complex structure for adjusting the angle of the photography and measurement components, a high failure rate, and a high production cost.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] like Figure 1-Figure 8 As shown, a measuring device for space planning includes a photographing and measuring component detachably fixedly connected to the lower end of a drone 1.

[0033] The lower end of the drone 1 is provided with a plurality of supporting legs 2. When the drone 1 lands, the supporting legs 2 are in contact with the ground, and when the drone 1 lands, the photographing and measuring components can be prevented from contacting the ground.

[0034] The photographic measurement assembly includes a mounting tube 3, which is made of engineering plastic material. Specifically, a plurality of mounting seats 4 are fixed to the upper end of the mounting tube 3, and the mounting seats 4 are fixed to the lower end of the drone 1 by screws.

[0035] The lower end of the installation tube 3 is coaxially rotatably connected with a rotating ring 5. Specifically, the lower end of the installation tube 3 is coaxially provided with an annular groove, in which a snap ring 6 is slidably clamped, and the rotating ring 5 is coaxially fixedly connected with the snap ring 6.

[0036] The rotating ball 7 is rolled and clamped in the lower end of the installation tube 3 and the rotating ring 5, and the rotating ball 7 is concentric with the installation tube 3. The interior of the rotating ball 7 is hollow. Specifically, the inner edge of the lower end of the installation tube 3 and the inner edge of the rotating ring 5 form an arc surface 20, and the outer edge of the rotating ball 7 contacts the arc surface 20.

[0037] A fixed ring 9 is concentrically fixed to the rotating ball 7 below the rotating ring 5 . The fixed ring 9 is connected to the rotating ring 5 via a plurality of springs 8 . A measuring instrument 10 is concentrically installed in the lower part of the rotating ball 7 .

[0038] An inner rod 15 is fixed inside the upper end of the installation tube 3, and an electric telescopic rod 16 is fixed at the lower end of the inner rod 15. The electric telescopic rod 16 is concentric with the installation tube 3. A connecting plate 17 is fixed at the lower end of the electric telescopic rod 16, and motors 18 are fixed at both ends of the connecting plate 17. The two motors 18 are symmetrically arranged according to the axis of the installation tube 3, and the axis of the motor 18 is perpendicular to the axis of the electric telescopic rod 16. Rollers 19 are concentrically fixed on the output shafts of the motors 18. Specifically, the rollers 19 are rubber wheels.

[0039] The electric telescopic rod 16 and the motor 18 are electrically connected to the controller and the power supply of the drone 1 , and the measuring instrument 10 is wirelessly connected to the handheld terminal that controls the drone 1 .

[0040] After the drone 1 is lifted off and hovers, the measuring instrument 10 can be started to take pictures and measure the position below it.

[0041] When the shooting angle of the measuring instrument 10 needs to be changed, the electric telescopic rod 16 is extended through the handheld terminal, and the electric telescopic rod 16 makes the two motors 18 and the two rollers 19 move downward through the connecting plate 17. When the electric telescopic rod 16 is extended, the two rollers 19 are in contact with the rotating ball 7. Since the rotating ball 7 is concentric with the mounting tube 3, the electric telescopic rod 16 is concentric with the mounting tube 3, and the two motors 18 are symmetrically arranged according to the axis of the mounting tube 3, the two motors 18 are symmetrical according to the vertical axis of the rotating ball 7, as shown in FIG. Figure 7 As shown, the two motors 18 are started simultaneously so that the two rollers 19 rotate in the same direction. The rollers 19 can drive the lower end of the rotating ball 7 to move forward or backward. During the process of the lower end of the rotating ball 7 rotating forward or backward, the measuring instrument 10 in the rotating ball 7 rotates accordingly, and the lower end of the measuring instrument 10 deflects toward the front or rear side, thereby adjusting the shooting angle of the measuring instrument 10.

[0042] When the lower end of the rotating ball 7 rotates toward the front or rear, the fixed ring 9 rotates accordingly. When the lower end of the rotating ball 7 rotates toward the front, the spring 8 on the front is compressed and the spring 8 on the rear is stretched. Conversely, when the lower end of the rotating ball 7 rotates toward the rear, the spring 8 on the rear is compressed and the spring 8 on the front is stretched.

[0043] When the lower end of the measuring instrument 10 is deflected to the front or rear side and still cannot meet the shooting measurement angle requirement, the lower end of the measuring instrument 10 can be kept deflected to the front or rear side, and then the two motors 18 are started and the output shafts of the two motors 18 rotate in opposite directions. At this time, the rotating ball 7, the rotating ring 5, the clamping ring 6, the fixing ring 9, the spring 8 and the measuring instrument 10 rotate in the circumferential direction of the mounting tube 3, thereby further changing the shooting measurement angle of the lower end of the measuring instrument 10, so that the lower end of the measuring instrument 10 can be aligned with the shooting measurement position. After shooting and measuring, the measuring instrument 10 wirelessly transmits the measurement information of the shooting measurement position to the handheld terminal controlling the drone 1.

[0044] After the measuring instrument 10 has finished shooting and measuring, the motor 18 is rotated and restored. At the same time, under the elastic force of the spring 8, the rotating ball 7, the fixing ring 9 and the measuring instrument 10 are restored.

[0045] The lower end of the fixing ring 9 is detachably fixedly connected with an arc-shaped transparent cover 13, which is concentric with the fixing ring 9. A plurality of limit blocks 12 are fixed on the upper end of the transparent cover 13, and a limit groove 11 corresponding to the limit block 12 is opened on the lower end of the fixing ring 9. A magnet is fixed in the limit groove 11. The limit block 12 is made of iron. The limit block 12 is inserted into the limit groove 11 and is magnetically attracted by the magnet. A rubber pad 14 is fixed on the upper end of the transparent cover 13, and the transparent cover 13 is in sealing contact with the fixing ring 9 through the rubber pad 14.

[0046] By providing the transparent cover 13 , the measuring instrument 10 can be effectively dustproof and protected.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
