[0002] This application claims priority to Chinese Patent Application No. 2024226953510, filed on November 6, 2024, entitled "A Detachable and Retractable Vehicle-Mounted Concrete Mixture Monitoring Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of vehicle-mounted concrete mixture monitoring technology, and in particular to a retractable vehicle-mounted concrete mixture monitoring device that is easy to disassemble. Background Technology

[0004] Concrete has become one of the most widely used building materials, playing an irreplaceable role in the construction industry. Ready-mixed concrete has the most applications, ranging from civil and rural buildings to urban infrastructure projects such as railways, highways, bridges, and tunnels. It plays a significant role in today's rapidly developing modern cities and the resettlement of large populations, making the quality of ready-mixed concrete particularly important. However, ready-mixed concrete requires a significant amount of transportation time from production to pouring. As the cement hydration reaction progresses, the concrete's workability gradually decreases, a phenomenon known as slump loss over time. Therefore, most batching plants use retarders to reduce performance loss during transportation.

[0005] Currently, some companies have developed remote vehicle-mounted monitoring devices. These devices, combined with admixture addition systems, allow technicians to monitor the concrete mix in the concrete mixer truck in real time from their mobile devices, and add admixtures according to actual construction needs. However, since concrete mix inevitably sprays onto the camera during use, the installation method and structural design make disassembly of the internal structure difficult, resulting in significant maintenance challenges later on.

[0006] To address the above issues, a retractable vehicle-mounted concrete mixture monitoring device that is easy to disassemble was designed.

[0056] In one embodiment of this disclosure, the drive device 3 is connected to the cover plate 2 and the camera protective cover 5 by any one of screw fastening, pin structure or glue bonding.

[0057] In one embodiment of this disclosure, the angle of the camera protective cover 5 is adjustable.

[0058] In one embodiment of this disclosure, the driving device 3 is either a cylinder or an electric telescopic rod. This allows for convenient longitudinal movement of the camera protective cover 5 within the housing 1, improving the stability of the movement of the camera 54 and the supplementary light 53.

[0059] In one embodiment of this disclosure, the camera 54 is any one of a detachable pinhole network camera, a miniature network camera, a tiny network camera, or a stabilized action camera. This improves the monitoring performance of the camera 54.

[0060] In one embodiment of this disclosure, the power supply voltage of the supplementary light 53 is 12-24V. This ensures stable supplementary lighting from the supplementary light 53, improves the monitoring effect of the camera 54, and facilitates technicians in assessing the state of the concrete mixture.

[0061] In one embodiment of this disclosure, referring to Figures 5 and 6, the housing 1 is installed outside the feed hopper 6, and the housing 1 is located within the gap 7 between the feed hopper 6 and the mixing drum 8. This ensures that the monitoring device is unaffected by splashing concrete mixture, while also preventing the monitoring device from interfering with the concrete feeding.

[0062] Optionally, the housing 1 is mounted on the outer plane of the feed hopper 6.

[0063] Optionally, the bottom opening of the housing 1 is connected to the discharge port of the feed hopper 6.

[0064] In one embodiment of this disclosure, referring to Figures 1 to 6, the operation of the easily detachable, retractable vehicle-mounted concrete mixture monitoring device is briefly described as follows:

[0065] In use, the remote monitoring device, i.e., the housing 1, is first installed outside the feed hopper 6 and within the gap 7 between it and the mixing drum 8, preferably on the outer surface of the feed hopper 6. The drive unit 3 and the camera protective cover 5, mounted on the cover plate 2, are then inserted into the housing 1 via the handle 4. The cover plate 2 is then installed on the opening of the housing 1, sealing the opening so that during the loading process of the mixer truck, when the concrete mixture enters the mixing drum 8 through the feed hopper 6, the monitoring device is not affected by the splashing of the concrete mixture, resulting in better protection. The camera 54 and the supplementary light 53 are installed inside the camera protective cover 5 and fixed to the camera by screws using the mounting bracket 57. On the protective cover 5, the power cord and network cable of the camera 54 and the fill light 53 are passed out through the side wire hole 55 of the camera protective cover 5. A glass plate 58 is installed on the front cover 52 of the camera protective cover 5 to protect the internal structure of the camera protective cover 5 from mud, water and other contaminants. A black opaque sleeve 59 is also installed on the front cover 52 to prevent the fill light 53 from interfering with the imaging of the camera 54. The front cover 52 and the rear cover 51 are connected by threads, with a waterproof ring 56 in the middle. The front cover 52 is a replaceable structure. When the glass plate 58 is dirty and cannot be cleaned with water, the front cover 52 can be unscrewed and replaced. The old cover can be reused after cleaning or replacing the glass plate 58.

[0066] In practical use, when it is necessary to observe the state of the concrete mixture inside the mixing drum 8, the drive device 3 drives the camera protective cover 5 and the supplementary light 53 and camera 54 inside the housing 1 to move downwards, so that the camera 54 faces the concrete mixture directly. When observation is not required, the drive device 3 drives the camera protective cover 5 and the supplementary light 53 and camera 54 inside the housing 1 to move upwards, which can adjust the position of the camera 54 and prevent concrete from splashing or backflowing when the camera 54 does not need to observe the inside of the mixing drum 8, thus avoiding damage to the structure of the camera protective cover 5.

[0067] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
