[0030] Reference Figure 1-6 ,
[0031] A truck unloading pump assembly includes: a drive pump body 1, a first connecting pipe 2, a second connecting pipe 3, and a pressure relief pipe 4. The first connecting pipe 2 is connected to the tank body of a tanker truck, and the second connecting pipe 3 is connected to a storage container, which is a box used to store liquid leaking from the tanker truck. The inlet of the drive pump body 1 is connected to the first connecting pipe 2, and the outlet of the drive pump body 1 is connected to the second connecting pipe 3. The pressure relief pipe 4 is connected to the second connecting pipe 3 and is used to connect to an external pressure relief tank. A control valve 5 is installed on the pressure relief pipe 4. The pressure relief tank is a container; the pressure relief tank and the pressure relief pipe 4 prevent overflow after the liquid in the storage container is full, thereby avoiding liquid overflow and making the unloading process more stable and reliable.
[0032] Specifically, it also includes a thermal imager 6, which is used to detect temperature changes in the first connecting pipe 2 and the second connecting pipe 3. When a leak occurs in either the first connecting pipe 2 or the second connecting pipe 3, the leaking liquid will have a significant temperature difference with the surrounding gas, allowing for timely detection and repair. The tanker truck is transporting liquid nitrogen.
[0033] Specifically, it also includes a driving component 8, which is used to move the thermal imager 6 so that the thermal imager 6 can detect the temperature changes of the first connecting pipe 2 and the second connecting pipe 3 at different positions. The driving component 8 is used to drive the thermal imager 6 to rise, fall, and rotate.
[0034] Specifically, the driving component 8 includes: a mounting bracket 7, a drive motor 81, a first electric push rod 82, and a connecting plate 83; the mounting bracket 7 is used to mount the drive motor 81 and the first electric push rod 82; the thermal imager 6 is mounted on the connecting plate 83; the drive motor 81 is used to drive the connecting plate 83 to rotate, and the first electric push rod 82 is used to drive the connecting plate 83 to rise and fall.
[0035] Specifically, a circular groove 84 is formed on the connecting plate 83. A slider 85 is provided at the output end of the first electric push rod 82. The slider 85 is slidably connected to the circular groove 84, and the first electric push rod 82 can drive the connecting plate 83 to rise and fall through the slider 85. A telescopic rod is provided at the output end of the drive motor 81, and the output end of the drive motor 81 is connected to the connecting plate 83 through the telescopic rod. This realizes the rotation and raising and lowering of the connecting plate 83, enabling the thermal imager 6 to be used in different positions, with a wider detection range and relatively more accurate detection results.
[0036] Specifically, a movable carrier is provided below the mounting frame 7. In this application, the movable carrier is a movable trolley, which facilitates the relocation of the mounting frame 7 and allows for easy switching to different positions when multiple tank trucks are unloading at different locations.
[0037] Specifically, a rotational power structure 9 is provided on the connecting plate 83. This structure drives the thermal imager 6 to rotate along a first axis; the drive motor 81 drives the thermal imager 6 to rotate along a second axis; the first axis is perpendicular to the second axis. Specifically, the rotational power structure 9 includes a second electric push rod 91 and a hinge seat 92. The thermal imager 6 is mounted on the hinge seat 92, which is mounted on the connecting plate 83. One end of the second electric push rod 91 is hinged to the connecting seat, and the other end is connected to the thermal imager 6. Thus, the extension and retraction of the second electric push rod 91 drives the rotation of the thermal imager 6.
[0038] Specifically, the mounting bracket 7 has two layers, each forming a support surface. The first electric push rod 82 is set on the upper support surface, and the drive motor 81 push rod is set on the lower support surface. Thus, the drive motor 81 and the first electric push rod 82 are installed in a staggered manner, which can better reduce the space occupied.
[0039] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
