[0012] 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 of the embodiments.

[0013] Please also see Figure 1 and Figure 2 , are schematic diagrams of the structures of the towing unit 1 and the plug connector 31 in the tunnel illumination detection device provided by the present invention.

[0014] The tunnel illumination detection device comprises a traction unit, a trailer unit 1, a distance measuring unit 2, an illuminometer 3 and a controller 4.

[0015] The traction unit is a motor vehicle with a towing hook at its rear. The traction unit is a commonly used prior art, and will not be described in detail here, nor will any drawings be drawn.

[0016] The trailer unit 1 is composed of a longitudinal rod 11 and two cross rods, which are welded to form a "S"-shaped structure. For ease of description, the two cross rods are respectively recorded as a front cross rod 12 and a rear cross rod 13. A hook 111 is provided at the end of the longitudinal rod 11 for connecting with the towing hook of the towing unit, so that the towing unit tows the trailer unit 1 and various components of its load to move together.

[0017] A front cross bar 12 is provided in the middle of the longitudinal bar 11, and a roller 121 is installed at both ends of the front cross bar 12 through a bearing, which is used to carry the trailer unit 1. A distance measuring unit 2 is provided near both ends of the front cross bar 12, which is used to measure the number of rotations of the roller 121, and then calculate the moving distance of the trailer unit 1, thereby realizing the distance measurement function.

[0018] The rear cross bar 13 is provided at the tail of the longitudinal rod 11, and an inverted "T"-shaped through slot 131 is provided on the upper surface of the rear cross bar 13 along its axial direction and passes through both ends thereof. The illuminometer 3 is an existing part and will not be described in detail here. A plug connector 31 is provided at the bottom of the illuminometer 3, and the illuminometer 3 is installed in the through slot 131 using the plug connector 31.

[0019] The plug connector 31 includes a cover 311, a spring 312 and a base 313 which are arranged in sequence. The upper end of the cover 311 is connected to the bottom of the illuminometer 3, the diameter of the connecting part is slightly smaller than the width of the upper opening of the through slot 131, the length is slightly larger than the thickness of the upper opening of the through slot 131, the diameter of the cover 311 is slightly smaller than the inner width of the through slot 131, and the length is smaller than the inner height of the through slot 131.

[0020] The lower end of the cover 311 is provided with a groove, in which the spring 312 and the base 313 are both accommodated. The side wall of the base 313 abuts against the inner wall of the groove of the cover 311. When the spring 312 is in a relaxed state, the base 313 will not be pushed out of the cover 311; when the spring 312 is in a compressed state, the base 313 can be completely received in the groove of the cover 311.

[0021] After the base 313 is pressed into the rear cover 311, the plug connector 31 can be inserted into the through slot 131 from the end thereof. Under the action of the spring 312, the base 313 and the cover 311 are respectively pressed against the upper and lower inner walls of the through slot 131 to fix the illuminometer 3. After being inserted into the through slot 131, the illuminometer 3 can be pushed to a suitable position.

[0022] A controller 4 is fixedly arranged above the intersection of the longitudinal bar 11 and the front cross bar 12, and the controller 4 is connected to the distance measuring unit 2 and the illuminance meter 3 through a circuit. The controller 4 should have the functions of controlling the distance measuring unit 2 and the illuminance meter 3 to open and close, and reading and storing the data measured by the distance measuring unit 2 and the illuminance meter 3.

[0023] When in use, multiple illuminometers 3 are installed at designated positions on the rear crossbar 13, and the trailer unit 1 is connected to the towing hook of the traction unit. The distance measuring unit 2 and the illuminometer 3 are controlled to start, and the traction unit is controlled to start and travel along the tunnel. During the travel, the distance measuring unit 2 sends a distance signal to the controller 4, and the controller 4 records and stores the readings of each illuminometer 3 at designated intervals based on the distance signal, and detects the illuminance value at a designated position on the travel lane at high speed.
