[0032] Please see Figures 1 to 5 This utility model provides a technical solution: a calibration device for displaying a flame gauge detection range diagram, comprising: an instrument positioning base 5, a gimbal motor 16, an inner turntable 17, a laser ranging module 12, a mounting plate 14, a camera module 7, a flat needle roller bearing 18, a first fixed housing 1, a second fixed housing 3, an outer turntable 4, and a controller.

[0033] The instrument positioning base 5 is fixedly connected to the housing of the flame detector by multiple screws;

[0034] The stator of the gimbal motor 16 is fixedly installed in the groove inside the instrument positioning seat 5;

[0035] The inner turntable 17 is fixedly connected to the rotor of the gimbal motor 16 by four hexagonal screws 6. The inner turntable 17 has a hole in the center. The wires of the camera module 7 and the laser rangefinder module 12 pass through the hole and the slip ring of the gimbal motor 16, and then lead out to the controller through the wire hole of the instrument positioning seat 5.

[0036] The laser ranging module 12 is fixedly mounted on the inner turntable 17 via the mounting plate 14. The laser ranging module 12 is fixed to the mounting plate 14 via the second cross screw 8 and the second nut 9. The mounting plate 14 is then fixed to the inner turntable 17 via the third cross screw 2.

[0037] The camera module 7 is fixedly located at the center of the entire device and inside the first fixed housing 1. The camera module 7 is fixedly installed inside the first fixed housing 1 by the first cross screw 10 and the first nut 11. The first fixed housing 1 is located at the center of the calibration device.

[0038] A flat needle roller bearing 18 is disposed between the instrument positioning seat 5 and the inner turntable 17. The flat needle roller bearing 18 is interference-fitted in the groove on the inner side of the instrument positioning seat 5. The bottom of the inner turntable 17 is provided with a protrusion, which is pressed against the flat needle roller bearing 18.

[0039] The outer turntable 4 is fixedly installed on the outer ring of the instrument positioning seat 5. The outer turntable 4 is fixed on the outer ring of the instrument positioning seat 5 by the fourth cross screw 13.

[0040] The second fixed housing 3 is mounted on the outer turntable 4 by multiple fifth cross screws 15.

[0041] The controller is electrically connected to the gimbal motor 16, the camera module 7, and the laser ranging module 12.

[0042] The specific usage and function of this embodiment are as follows: Based on the traditional method of estimating the working range of the instrument, automatic rotation, laser ranging, and on-site photography are added, so that the instrument's detection range can be directly displayed on the computer, which greatly reduces the risk factor for on-site construction personnel and reduces the difficulty of adjusting the instrument's detection angle to ensure full coverage.

[0043] The laser rangefinder is fixed as a module on the inner turntable 17, which is in turn fixed to the rotor of the gimbal motor 16. The camera module is fixed on the outer turntable 4, which is fixed to a turntable positioning seat to ensure that the camera module does not move and affect the image capture. The turntable positioning seat is fixed to the instrument surface to ensure concentricity, and the stator of the gimbal motor 16 is fixed in the groove inside the positioning seat. The rotation of the gimbal motor 16 drives the inner turntable 17 to rotate the laser rangefinder module 12. The camera module remains at the center and stable. It takes a picture after each rotation angle. The pictures containing the laser and the corresponding distance are combined into one image, and the detection range picture is output. After the operation is completed, the gimbal motor 16 will automatically return to its original position to ensure that no rotational torque is applied to the data cable, which could lead to the data cable breakage.

[0044] The inner turntable 17 is provided with a boss that presses on the needle roller bearing to ensure uniform pressure on the circumferential motion plane of the turntable, smooth rotation, and no derailment from the track. It is simple and reasonable. The laser ranging module 12 has an unobstructed emission window, which ensures more stable adjustment of the laser ranging module 12 during normal operation. It is simple and reliable.
