It includes a movable base 11, which provides stable support and convenient mobility for the entire device, thus expanding its working range. A lifting bracket is mounted on the movable base 11, comprising an outer sleeve 12 and an inner sleeve 13. The inner sleeve 13 and outer sleeve 12 enable stable telescopic adjustment, improving the smoothness of the lifting action. The outer sleeve 12 is fixedly connected to the movable base 11, and the inner sleeve 13 passes through it. An electric push rod 14 is located inside the outer sleeve 12, with its movable rod connected to the inner sleeve 13. The electric push rod 14 provides lifting power, improving the controllability of the lifting operation.

[0024] like Figure 2 As shown, a rotating platform is provided below the lifting bracket. The rotating platform includes a turntable 15 and a drive motor 16. The drive motor 16 is located at one end of the inner sleeve 13, and the turntable 15 is sleeved on the output shaft of the drive motor 16. The rotating platform enables omnidirectional horizontal detection, improving the detection coverage of the device. The drive motor 16 provides stable rotational power, enhancing the reliability of the rotational action.

[0025] like Figure 2 , 3As shown, the turntable 15 has multiple mounting slots on its side. The thermal infrared imager 17, the visible light camera 18, and the laser rangefinder 19 are mounted in these slots. The controller 23 is electrically connected to the thermal infrared imager 17, the visible light camera 18, and the laser rangefinder 19. By using multiple detection instruments, multi-dimensional detection data can be acquired, improving the accuracy of the device's detection. The mounting slots also allow for the installation of detection instruments, enhancing their stability during operation.

[0026] The mobile base 11 has a protective housing 21 on top, which protects the internal equipment from external environmental influences, improving the device's durability and stability. The lifting bracket and rotating platform are located inside the protective housing 21. A display screen 22 and a controller 23 are located on the top of the protective housing 21. These components display the detection results and facilitate operation, enhancing the device's human-machine interface. A temperature sensor array 24 is located at the bottom of the rotating platform, providing additional detection data and improving the accuracy of leakage assessment. The controller 23 is electrically connected to the display screen 22 and the temperature sensor array 24. This electrical connection ensures rapid data transmission and processing, improving the device's operating efficiency.

[0027] like Figure 2 , 3 As shown in Figure 4, a protective cover 25 is fitted onto the turntable 15, and the temperature sensor array 24 is located at the bottom of the turntable 15. The protective cover 25 protects the testing instrument from damage and improves its service life.

[0028] The protective casing 21 houses an energy storage battery 26, and the controller 23 houses a wireless transmission module. The controller 23 is electrically connected to the energy storage battery 26 and the wireless transmission module. The energy storage battery 26 ensures the device can operate normally without an external power source, thus improving its battery life. The wireless transmission module enables remote data transmission and monitoring.

[0029] The mobile base 11 has multiple sets of casters 27 at its bottom, and a fixed bracket 28 is provided on one side of the protective shell 21. A lighting device 29 is mounted on the fixed bracket 28. The casters 27 enable the device to move, improving its mobility. The fixed bracket 28 and lighting device 29 provide illumination in low-light environments, ensuring normal operation of the testing work and enhancing the device's ability to function in various environments.

[0030] The thermal infrared imager 17 can be a FLIRE54 model thermal infrared imager; the visible light camera 18 can be a MarkIV model camera; the laser rangefinder 19 can be a DISTOD2 model laser rangefinder; the display screen 22 can be a 27UL850 model display screen; the temperature sensor array 24 can be an array composed of DS18B20 model temperature sensors; the lighting device 29 can be a JW7622 model lighting device; the controller 23 can be a TMS320 series controller; and the wireless transmission module can be an ME909s-821 model wireless transmission module.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In use, the device is first moved to the foundation area to be inspected using the multiple sets of casters 27 at the bottom of the movable base 11. Once in the designated position, the casters 27 are locked to ensure stability. The extension and retraction of the inner sleeve 13 are adjusted using the electric push rod 14 of the lifting bracket, thereby adjusting the rotating platform and the inspection instruments mounted on it to a suitable height. The drive motor 16 rotates the turntable 15, enabling the thermal infrared imager 17, visible light camera 18, and laser rangefinder 19 to scan the foundation from all directions. During the inspection, the thermal infrared imager 17 captures the temperature distribution on the foundation surface, the visible light camera 18 acquires an image of the foundation's appearance, the laser rangefinder 19 measures the distance between the device and various points on the foundation, and the temperature sensor array 24 collects the foundation's temperature data. These multi-source data are transmitted to the controller 23 for comprehensive processing and analysis.

[0033] The display screen 22 shows the detection images and analysis results, allowing operators to intuitively understand the leakage situation of the foundation. The energy storage battery 26 inside the protective casing 21 provides continuous power support to the equipment, ensuring normal operation for a period of time without an external power source. The wireless transmission module transmits the detection data to a remote monitoring terminal for convenient remote monitoring and data analysis. After the detection work is completed, the equipment height is lowered again using the lifting bracket, and the casters 27 are unlocked to move the equipment away.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
