[0047] The working principle of the utility model is:

[0048] When the detection equipment is used, in the non-working state, the detection equipment is in the moving or storage mode, at this time, the pressure plate 12 in the control member is in the low position under the action of gravity, the main pressure plate 15 at the bottom continuously presses on the inclined pressure plate 10 at the top of the protective plate 8, the pressing force forces the multiple triangular plate-shaped protective plates 8 to rotate around the outer wall of the microwave detection equipment 7, finally makes each protective plate 8 rotate and fold, completely covers the detection end below the microwave detection equipment 7, forms protection, when it is needed to start detection, the operator pulls the pull handle 5 in the inner ring of the handrail 4, the pull handle 5 pulls the hook 16 connected with the pressure plate 12 upward through the two pull ropes 6 penetrating the push rod 3 and the base 2, so as to lift the pressure plate 12 and the main pressure plate 15, makes them separate from the pressure plate 10 on the protective plate 8, after the pressure is removed, each protective plate 8 naturally rotates downward and opens under the action of its own gravity, exposes the detection end of the microwave detection equipment 7, then, the operator can push the detection equipment, uses the microwave detection equipment 7 to emit microwaves to the road surface and receives the reflected signals, judges the internal diseases of the road surface by analyzing the signals, after the detection is completed, the pull handle 5 is loosened, the pressure plate 12 is lowered again under the action of its own gravity and the reset spring 14, the main pressure plate 15 presses the pressure plate 10 again, drives the multiple sets of protective plates 8 to rotate and fold, protects the detection end again, completes a working cycle, in the process, the surrounding ropes 11 on the outer wall of the protective plate 8 can block the small stones splashing when the protective plate 8 is opened, provide additional buffer protection;

[0049] When working, corresponding working mode selection can be carried out according to the needs, when the buckle member buckles and fixes the pull handle 5, the multiple sets of protective plates 8 are all opened, so that the detection end of the microwave detection equipment 7 is always in the opened state, can continuously detect and work;

[0050] According to the working area condition, the buckle member can not be used to fix the pull handle 5, at this time, the user always pulls the pull handle 5 by fingers, so as to drive the multiple sets of protective plates 8 to open, when the user's fingers are half loosened or completely loosened, the multiple sets of protective plates 8 can be closed or completely closed, so that the microwave detection equipment 7 can be protected at any time when working, this mode is more suitable for bad weather, road sections with many vehicles and road sections with frequent data recording, so that the detection end of the microwave detection equipment 7 can be effectively protected in real time when working.

[0051] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
