[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a towed rotary sweep array three-dimensional roadbed radar device, comprising a trailer bracket 1, a rotating platform mechanism 2 is installed on one side of the upper surface of the trailer bracket 1, a first geological radar 3 is installed in the middle of the upper surface of the trailer bracket 1, and two second geological radars 4 are symmetrically installed on the other side of the upper surface of the trailer bracket 1;

[0035] The rotating platform mechanism 2 is used to drive the radar to rotate and cooperate with the movement of the trailer bracket 1 to form a spiral scanning section;

[0036] The rotating platform mechanism 2 includes a platform bracket 201, a connecting frame 205 and two third geological radars 206;

[0037] The platform bracket 201 is installed on one side of the upper surface of the trailer bracket 1, the connecting frame 205 is arranged in the middle of the inner side of the platform bracket 201, and two third geological radars 206 are symmetrically installed at both ends of the connecting frame 205;

[0038] Among them, the frequency bands of the two third geological radars 206, the first geological radar 3 and the second geological radar 4 are all different.

[0039] In one embodiment, the rotating platform mechanism 2 further includes a storage cylinder 202, a motor frame 203 and a driving motor 204;

[0040] Among them, the top of the storage barrel 202 is rotatably connected to the top of the inner wall of the platform bracket 201, the upper surface of the connecting frame 205 is fixedly connected to the bottom of the storage barrel 202, the motor frame 203 is installed at the bottom of the inner wall of the platform bracket 201, the driving motor 204 is installed inside the motor frame 203, the output shaft of the driving motor 204 passes through the motor frame 203 and is fixedly connected to the bottom of the connecting frame 205, the outer wall of the platform bracket 201 is fixedly connected with a lead frame 7, one end of the lead frame 7 is installed with a connector 9, and a collector ring 8 is installed on the top of the inner wall of the storage barrel 202, and the connector 9 is adapted to the collector ring 8;

[0041] The collector ring 8 and the connector 9 are provided so as to connect the two third geological radars 206 , and ensure that the data detected by the third geological radar 206 can be fed back normally under the condition that the third geological radar 206 can rotate with the connecting frame 205 .

[0042] In one embodiment, the speed of the drive motor 204 is 100-500 rpm;

[0043] The output shaft of the driving motor 204 drives the connecting frame 205 and the two third geological radars 206 to rotate at 100-500 rpm.

[0044] In one embodiment, the first geological radar 3 is a fixed 400M geological radar, which is used for covering scanning 1-3 meters underground, the two second geological radars 4 are 300M geological radars, with a detection depth of 3-10 meters, and the two third geological radars 206 are 100M geological radars, with a detection depth of 10-30 meters;

[0045] By utilizing five geological radars and arranging them in arrays of different frequency bands, a high-density coverage scan of the roadbed is formed from the surface to the depth. The lower the frequency of the geological radar, the deeper the detection depth and the lower the near-ground resolution; the higher the frequency, the shallower the detection depth and the higher the resolution; combining this characteristic of geological radar, using radars of different frequency bands and distributed arrays for simultaneous detection, high-resolution three-dimensional imaging technology from the surface to the depth is achieved.

[0046] In one embodiment, a trailer frame 6 is installed at the bottom of one side of the trailer bracket 1, and a wheel 5 is installed at the middle of the lower surface of the trailer bracket 1;

[0047] The trailer frame 6 is provided to connect the trailer bracket 1 to the vehicle.

[0048] When the present invention is working, the trailer bracket 1 is towed to the rear of a vehicle by using the trailer frame 6, and then the vehicle is used to drive the roadbed radar device to move as a whole.

[0049] When it is necessary to scan the roadbed, the output shaft of the driving motor 204 drives the connecting frame 205 and the two third geological radars 206 to rotate at 100-500rpm, and during the rotation, the third geological radar 206 is used to detect the roadbed to form a spiral scanning section, providing high-density geological information for the later three-dimensional imaging data processing; at the same time, the first geological radar 3 is used to perform a covering scan of 1-3 meters underground to form an intermediate layer geological imaging in accordance with the vehicle speed; the two second geological radars 4 are used to perform a 3-10 meter deep scan, so that five geological radars can be arranged in arrays of different frequency bands to form a high-density covering scan of the roadbed from surface to depth. The lower the frequency of the geological radar, the deeper the detection depth and the lower the near-ground resolution. The higher the frequency, the shallower the detection depth and the higher the resolution. Combined with this characteristic of the geological radar, radars of different frequency bands are used, and the array is distributed for simultaneous detection to achieve high-resolution three-dimensional imaging technology from surface to depth, so as to quickly check for roadbed safety hazards.

[0050] The collector ring 8 and the connector 9 are provided so as to connect the two third geological radars 206 , and ensure that the data detected by the third geological radar 206 can be fed back normally under the condition that the third geological radar 206 can rotate with the connecting frame 205 .

[0051] When the third geological radar 206, the first geological radar 3 and the second geological radar 4 detect geological information data, the data is collected through the terminal equipment, and the geological information is integrated and analyzed using data processing software, so as to utilize the characteristics of radars in different frequency bands to achieve high-resolution three-dimensional imaging from surface to depth, and then by analyzing the three-dimensional imaging results, roadbed safety hazards can be quickly checked.
