[0039] In this embodiment, the mobile device includes a mobile car 1 and a lifting frame 2 arranged on the mobile car 1. The bottom of the lifting frame 2 is connected to the mobile car 1 through a shock-absorbing spring bracket to prevent vibration during movement from causing damage to components in each module on the lifting frame 2.

When the mobile car 1 moves to the designated location, the wheel is limited by the wheel brake to stop the device from moving, so that the ground penetrating radar device 100 can work conveniently.

[0042] In this embodiment, the ground-penetrating unit 3 includes a transmitting antenna, a receiving antenna and a host. There is a certain distance between the transmitting antenna and the receiving antenna. The transmitting antenna is used to transmit high-frequency pulse electromagnetic wave signals underground, and the receiving antenna is used to receive reflected electromagnetic wave signals. The transmitting antenna, the receiving antenna and the host are all packaged in the packaging box of the ground-penetrating unit 3, which greatly reduces the influence of the peripheral equipment of the ground-penetrating unit 3 on its transceiver signals. A shockproof spring is arranged between the packaging box of the ground-penetrating unit 3 and the lifting frame 2, and preferably, a shockproof spring is arranged at the four corners of the bottom of the packaging box of the ground-penetrating unit 3.

[0043] In this embodiment, the battery module 4 is electrically connected to the ground-penetrating unit 3, the GNSS positioning module 5 and the master control module 6, and the battery module 4 can provide stable power output to meet the power requirements of other modules. The battery module 4 includes batteries of multiple modules such as the ground-penetrating unit 3, the GNSS positioning module 5, the master control module 6, etc., has strong environmental adaptability, can work normally under different temperature and humidity conditions, and is suitable for various application scenarios.

[0044] In this embodiment, the GNSS positioning module 5 is connected to the main control module 6 by communication, thereby realizing the signal connection with the ground-penetrating unit 3. The GNSS positioning module 5 and the ground-penetrating unit 3 are set at the same time, and the cooperation between the two can locate the detection position more accurately, especially for pipeline leak detection, the positioning accuracy directly affects the subsequent excavation and detection engineering quantity. The GNSS positioning system set in the GNSS positioning module 5 can usually provide high-precision positioning at the level of several meters to sub-meters, which is suitable for various applications that require accurate location information. At the same time, the GNSS positioning module 5 is packaged in a separate packaging box, which improves the anti-interference ability of the GNSS positioning module 5 to cope with the influence of weather, buildings and other factors on the signal.

[0045] In this embodiment, the master control module 6 is communicatively connected with each module such as the ground penetrating unit 3, the battery module 4, the GNSS positioning module 5, etc., and plays the overall control, coordination and scheduling functions in the device to ensure that each module works in coordination to achieve the optimization of the overall performance of the system.

[0046] In this embodiment, considering the compatibility of the detection radar device as a whole with additional functions or accessories, the detection device is also provided with an expandable module 7, which includes an expandable module packaging box. The expandable module packaging box is used for the subsequent installation of additional modules as needed, so as to facilitate the expansion of the functions of the detection radar device 100 and improve the flexibility and wide applicability of the detection radar device 100.

[0047] In this embodiment, the packaging boxes of the ground penetrating unit 3, GNSS positioning module 5, master control module 6 and battery module 4 and the expandable module packaging box are preferably embedded boxes, which are convenient for disassembly and assembly, and convenient for inspection and maintenance at any time when internal hardware fails.

[0048] In this embodiment, Figure 1 As shown, preferably, the GNSS positioning module 5 , the battery module 4 and the expandable module 7 are all arranged above the ground penetrating unit 3 .

[0049] In this embodiment, the detection device is also equipped with a human-machine interaction interface 61, and the human-machine interaction interface 61 is communicatively connected with the main control module 6. The human-machine interaction interface 61 has a display screen and a control panel. The control panel is provided with four buttons, which respectively control the opening and closing of the ground detection unit 3, the GNSS positioning module 5, the human-machine interaction interface 61 and the expandable module 7. The display screen on the human-machine interaction interface 61 can interact with the device by touch. The display interface includes real-time collected images and real-time location of data, and the image can also be optimized by performing data processing. In actual applications, the human-machine interaction interface 61 can be provided on the main control module 6, that is, the human-machine interaction interface 61 and the main control module 6 are integrated into a whole. Figure 1 As shown, the mobile cart 1 is provided with a liftable cart handle 11, and the master control module 6 and the human-machine interaction interface 61 are arranged on the cart handle 11 as a whole. Specifically, the two ends of the master control module 6 are rotatably connected to the cart handle 11 through a bracket, and an adjustment knob 8 is arranged between the two ends of the master control module 6 and the bracket, and the adjustment knob 8 is used to adjust the inclination angle of the master control module 6 relative to the bracket. In practical applications, the height of the master control module 6 can be adjusted by adjusting the height of the cart handle 11, and the inclination angle of the display screen on the human-machine interaction interface 61 can be adjusted by adjusting the adjustment knobs 8 at both ends of the master control module 6. By controlling the bracket to rotate relative to the cart handle 11, the master control module 6 and the human-machine interaction interface 61 are rotated relative to the cart handle 11 as a whole. Through the above-mentioned height adjustment, inclination angle adjustment and rotation adjustment of the master control module 6 and the human-machine interaction interface 61 as an integrated whole, the direction of the human-machine interaction interface 61 on the master control module 6 can be accurately controlled to adapt to the collection process in different environments.

[0050] In this embodiment, Figure 1As shown, the chassis of the mobile vehicle 1 is a frame structure with a hollow center. Since the lifting frame can drive the detection device to rise and fall relative to the ground, the chassis design with a hollow center allows roads with different terrains to enter the chassis, making it convenient for the ground detection unit 3 to detect different roads.

[0051] Furthermore, in this embodiment, the aforementioned lifting frame includes a mounting frame body, which is mounted on the chassis of the mobile vehicle 1. A lifting mechanism is provided below the mounting frame body to connect with the packaging box of the ground-penetrating unit 3. The lifting mechanism can drive the packaging box of the ground-penetrating unit 3 to rise and fall in the hollow space of the chassis of the mobile vehicle 1, thereby driving the GNSS positioning module 5, the battery module 4 and the expandable module 7 on the ground-penetrating unit 3 to rise and fall. The above-mentioned lifting mechanism can be an electric telescopic rod, an electric slide, a spiral lift, a cylinder or a hydraulic cylinder, etc. The lifting frame drives the ground-penetrating unit 3, the GNSS positioning module 5, the battery module 4 and the expandable module 7 to rise and fall, which is convenient for adjusting the detection position of the ground-penetrating unit 3 according to the terrain, so that the device can flexibly adapt to different working conditions.

[0052] When the ground penetrating radar device 100 needs to work outdoors, the staff first adjusts the height of the master control module 6 so that the display screen is flush with the line of sight, and then adjusts the distance between the ground penetrating unit 3 and the ground through the lifting mechanism of the lifting frame, so that the device can reach the best performance under the specified detection occasion. After the distance is determined, click the start button of the battery module 4 on the human-machine interaction interface 61, and the master control module 6, the ground penetrating unit 3, etc. are powered on and start working. Press the switch button of the GNSS positioning module 5 and the ground penetrating unit 3 in the master control module 6, and the ground penetrating radar device 100 starts working. Then the staff pushes the mobile car 1 to let the device move forward slowly for detection. While the device is pushed forward, the odometer is also measuring the distance the device has moved forward. Whenever it moves forward to a specified distance, the host of the ground penetrating unit 3 sends a signal to make the transmitting antenna emit high-frequency pulse electromagnetic waves underground. When electromagnetic waves pass through different substances, the electromagnetic waves are reflected due to the difference in dielectric constants. The receiving antenna collects the signal transmitted back from the underground, and transmits the signal to the human-machine interaction interface 61 through the host, so that the collected signal is displayed on the display screen.

[0053] As can be seen from the above, the ground-penetrating radar device 100 of the utility model integrates detection, control and display functions, realizes highly integrated functions, is easy to carry, is more suitable for outdoor exploration, and is conducive to improving work efficiency. At the same time, the ground-penetrating unit 3, the GNSS positioning module 5, the master control module 6, the battery module 4 and the expandable module 7 are respectively packaged by a packaging box, which realizes the grouping of each module of the ground-penetrating unit 3, the GNSS positioning module 5, the master control module 6, the battery module 4 and the expandable module 7. Each module can be debugged through the master control module 6, thereby solving the problems of the existing detection radar being inconvenient to carry and difficult to debug.

[0054] In addition, the positioning function of the ground-penetrating unit 3 is difficult to implement, and it is difficult to determine the detection position using only the odometer. Integrating the ground-penetrating unit 3 with the GNSS positioning module can effectively improve the positioning accuracy during radar detection, and can provide more accurate location information, thus facilitating the positioning of water leaks in urban pipe networks.

[0055] The setting of the human-computer interaction interface 61 can interact with the device by touch, and the display interface includes real-time acquisition images and real-time data positions, and the image can be optimized by performing data processing. The human-computer interaction interface 61 can process the acquired data in real time, which helps to improve work efficiency.

[0056] The master control module 6 calls each module to ensure that each submodule or component works in coordination to optimize the overall performance of the system. In actual applications, the master control module 6 can call several modules individually for viewing and processing according to needs.

[0057] Embodiment 2

[0058] like Figure 2 As shown, this embodiment provides a ground penetrating radar device 100, which is different from the first embodiment only in that the human-machine interaction interface 61 and the master control module 6 are separately arranged, for example, the master control module 6 is arranged on the mobile cart 1, and the human-machine interaction interface 61 is arranged on the above-mentioned cart handle 11. Specifically, the human-machine interaction interface 61 is a separate structure, and its two ends are rotatably connected to the cart handle 11 through a bracket, and an adjustment knob 8 is arranged between the two ends of the human-machine interaction interface 61 and the bracket, and the adjustment knob 8 is used to adjust the inclination angle of the human-machine interaction interface 61 relative to the bracket. In actual applications, the height of the human-computer interaction interface 61 can be adjusted by adjusting the height of the cart handle 11, and the inclination angle of the display screen on the human-computer interaction interface 61 can be adjusted by adjusting the adjustment knobs 8 at both ends of the human-computer interaction interface 61. The human-computer interaction interface 61 can be rotated relative to the cart handle 11 by controlling the bracket to rotate relative to the cart handle 11. Through the above-mentioned height adjustment, inclination angle adjustment and rotation adjustment of the human-computer interaction interface 61, the orientation of the human-computer interaction interface 61 can be accurately controlled to adapt to the collection process in different environments.

[0059] Except for the above differences, other structures of this embodiment are the same as those of the first embodiment and will not be described again.
