The following describes a detection device for detecting the radius of a ball curtain structure according to an embodiment of the present invention with reference to the drawings.

Referring to fig. 1 to 3, according to the utility model discloses a detection device for detecting spherical curtain structure radius, it includes base 1, first rotary mechanism, second rotary mechanism, distancer 2. The first rotating mechanism is rotatably connected with the base 1. The distance measuring instrument 2 is arranged on the first rotating mechanism through the second rotating mechanism and can rotate relative to the first rotating mechanism.

In this embodiment, the first rotating mechanism includes a rotating member 3 having a generally cylindrical shape, and the base 1 is provided with a circular guide rail 4 engaged with a lower end opening of the rotating member 3. The rotating member 3 can rotate relative to the circular guide rail 4, i.e. the base 1, under the driving of a driving mechanism, such as a motor, or an external force.

The second rotating mechanism includes two brackets 5 fixed to opposite sides of the rotating member 3, for example, the two brackets 5 are fixed to opposite outer walls of the rotating member 3 through bolts. The second rotating mechanism further comprises a rotating frame which is rotatably arranged on the two brackets 5, and the distance measuring instrument 2 is fixed on the rotating frame. The measuring instrument or the rotating frame can rotate relative to the rotating part 3 under the driving of a driving mechanism, such as a motor, or external force.

The rotating frame comprises two rotating shafts 6 which are oppositely arranged, and the two rotating shafts 6 are respectively and rotatably arranged on the two brackets 5; and the connecting piece 7 is fixedly connected with the two rotating shafts 6, and the distance measuring instrument 2 is fixed on the connecting piece 7. The support 5 comprises a supporting platform 8 for supporting one end of the rotating shaft 6 and a cover body 9 abutting against the outer peripheral wall of the rotating shaft 6, and the cover body 9 forms an arc-shaped groove matched with the rotating shaft 6. Supporting platform 8 retrains pivot 6 with lid 9 jointly, can form the resistance to the rotation of pivot 6, rotating turret, makes distancer 2 can stop at the position that needs at any time. Preferably, the middle of the distance measuring instrument 2 is connected with the connecting piece 7, and the force distances from the parts of the distance measuring instrument 2 positioned at the two sides of the connecting piece 7 to the axis of the rotating shaft 6 are equal.

The distance meter 2 comprises a transmitting unit 10 for transmitting the measuring radiation in the direction of the measuring object, and a receiving unit 11 for receiving the measuring radiation reflected by the measuring object. When the transmitting unit 10 rotates relative to the first rotating mechanism, the plane of the motion locus passes through the rotating shaft of the first rotating mechanism, namely the rotating shaft of the rotating part 3, and the rotating center of the transmitting unit 10 is located on the rotating shaft of the first rotating mechanism; the straight line where the measuring ray emitted by the emitting unit 10 is located passes through the rotation center of the emitting unit 10.

When detection device was used for detecting the spherical curtain structure radius, adjustment detection device's position made the rotation center of emission unit 10 be located the centre of sphere position of spherical curtain structure, rotated piece 3 and distancer 2 through the rotation, can realize the radius detection of spherical curtain structure optional position, arbitrary angle promptly. If the measuring ray emitted by the emitting unit 10 does not pass through the rotation center of the emitting unit 10, the radius of the measuring point of the spherical screen structure is equal to the length measured by the distance meter 2 plus the rotation radius of the emitting unit 10. If the measuring ray emitted by the emitting unit 10 passes through the rotation center of the emitting unit 10, the radius of the measuring point of the spherical screen structure is equal to the length measured by the distance meter 2 minus the rotation radius of the emitting unit 10. The detection device does not need to be subjected to position adjustment again in the detection process, so that the detection time of the spherical curtain structure construction process is saved, and the spherical curtain radius detection precision is improved.

Specifically, the base adjusting system comprises three adjusting bolts 12 distributed in an annular array, and the adjusting bolts 12 are matched with three screw holes formed in the base 1 and can be abutted against a support, such as the ground, a supporting platform and the like. The height, the inclination angle, the inclination direction, and the like of the base 1 can be adjusted by rotating the adjusting bolt 12, thereby adjusting the positions of the base 1 and the support.

In practical applications, if the center of the dome screen structure is located at a higher position, a supporting platform with a proper height can be added below the base 1 to increase the height of the position of the adjusting system, and then the base adjusting system is used to adjust the positions of the base 1 and the supporting platform, so that the rotation center of the launching unit 10 falls on the center of the dome screen structure.

In this embodiment, the base 1 is provided with a small circular hole 13 on the rotating shaft of the first rotating mechanism to assist in positioning the detection device.

In an application mode, the detection device is horizontally arranged, that is, a rotating shaft of the first rotating mechanism is perpendicular to a horizontal plane, the small circular hole 13 is moved to be located on the same plumb line with the center of a sphere of a spherical screen structure, and the distance meter 2 is adjusted to enable the transmitting unit 10 to vertically transmit the measuring ray upwards, because in this embodiment, the measuring ray transmitted by the transmitting unit 10 does not pass through the rotating center of the transmitting unit 10, the base adjusting system is adjusted according to the length measured by the distance meter 2 and the length value after the rotating radius of the transmitting unit 10, until the length value after the length measured by the distance meter 2 and the rotating radius of the transmitting unit 10 is equal to the radius of the spherical screen structure, at this moment, the rotating center of the transmitting unit 10 falls on the center of the sphere of the spherical screen structure, and the detection device is positioned. Of course, if the measurement ray emitted by the emitting unit 10 passes through the rotation center of the emitting unit 10, the base adjustment system needs to be adjusted according to the length value obtained by subtracting the rotation radius of the emitting unit 10 from the length measured by the distance meter 2 until the length value obtained by subtracting the rotation radius of the emitting unit 10 from the length measured by the distance meter 2 is equal to the radius of the spherical screen structure, and at this time, the rotation center of the emitting unit 10 falls on the spherical center of the spherical screen structure, and the positioning of the detecting device is completed.

In an alternative embodiment, the base 1 is provided with a marker on the axis of rotation of the first rotation mechanism instead of the small circular hole 13.
