Description

Technical Field

[0001] This utility model relates to the field of data acquisition technology, and in particular to an underwater multi-sensor data acquisition device. Background Technology

[0002] Currently, in the field of underwater object detection, it is often necessary to use multiple types of sensors simultaneously to obtain comprehensive information. For example, optical cameras are used to acquire visible light images, lidar is used to acquire distance and depth data, or infrared cameras are used to detect temperature differences.

[0003] However, existing underwater detection equipment often struggles to integrate multiple sensors into a single device, typically requiring multiple sets of equipment to operate separately, resulting in cumbersome and difficult data acquisition procedures. Furthermore, the harsh operating environment of underwater equipment demands extremely high levels of sealing and waterproofing performance. Traditional equipment often relies on a single sealing structure, making it susceptible to water ingress and damage if the seal fails, leading to insufficient reliability. In particular, for underwater infrared cameras, if ordinary glass windows are still used, the water environment and stray light can interfere with infrared imaging, causing the infrared sensors to malfunction.

[0004] In summary, there is an urgent need for a data acquisition device that integrates multimodal sensors and has a highly reliable seal in an underwater environment. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, one objective of this invention is to provide an underwater multi-sensor data acquisition device that integrates multiple sensors to synchronously acquire underwater data. It also incorporates an infrared interference-proof window and a double-waterproof redundant slot structure for the infrared sensor, thereby improving the diversity, reliability, and ease of use of the data acquisition.

[0006] To achieve the above objectives, this utility model provides an underwater multi-sensor data acquisition device, comprising: a main body shell defining a housing and multiple viewing windows; a multi-sensor device disposed within the housing and corresponding to each of the multiple viewing windows, wherein the multi-sensor device includes an infrared camera, which is positioned opposite to a germanium glass window among the multiple viewing windows; a water storage tank disposed at the bottom of the main body shell and connected to the main body shell; and a first cover plate covering the top of the main body shell to seal the multi-sensor device within the housing.

[0007] The underwater multi-sensor data acquisition device proposed in this utility model, through the integrated design of multi-modal sensors, enables the device to simultaneously acquire multiple data such as laser point clouds, visible light, event vision, and infrared thermal imaging, thereby improving the information richness and data synchronization of underwater detection. The application of germanium glass windows avoids the spectral interference of ordinary glass materials on infrared cameras, ensuring that infrared sensors can still produce clear images in complex underwater optical environments. The water storage tank structure at the bottom of the tank provides two waterproof barriers. Even if one seal fails and leaks, residual water will be stored in the water storage tank and will not directly enter the interior, greatly improving the sealing reliability of the device during long-term underwater operation.

[0008] In addition, the underwater multi-sensor data acquisition device proposed above according to this utility model may also have the following additional technical features:

[0009] Optionally, the multi-sensor device may also include a solid-state LiDAR, a high-speed camera, an RGB camera, and an event camera.

[0010] Optionally, the main housing is provided with multiple mounting bases, each for mounting each multi-sensor device.

[0011] Optionally, a second cover plate is also included, which covers the germanium glass window.

[0012] Optionally, it also includes a mounting bracket, which is fixedly mounted on the outside of the main body housing.

[0013] Optionally, it also includes a three-way pagoda-head wire harness outlet, which is welded and sealed onto the main body housing. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1 As shown in the figure, the underwater multi-sensor data acquisition device proposed in this embodiment of the present invention includes a main body shell 10, a multi-sensor device 20, a water storage tank 30, and a first cover plate 40.

[0022] The main body shell 10 defines a container and multiple viewing windows; a multi-sensor device 20 is disposed within the container cavity and is arranged correspondingly to each of the multiple viewing windows. The multi-sensor device 20 includes an infrared camera 205, which is arranged opposite to the germanium glass window 501 in the multiple viewing windows; a water tank 30 is disposed at the bottom of the main body shell 10 and connected to the main body shell 10; a first cover plate 40 is placed on the top of the main body shell 10 to seal the multi-sensor device 20 within the container cavity.

[0023] It should be noted that the main body shell 10 is made of stainless steel. The stainless steel shell is a sealed cavity structure with robust pressure resistance and corrosion resistance, used to house the various sensor devices inside.

[0024] Specifically, one end of the main housing 10 is closed by a removable first cover plate 40; the first cover plate 40 is fixed to the main housing 10 by bolts. A germanium glass window 501 is provided on one side of the main housing 10, serving as the observation window for the infrared camera 205; the germanium glass window 501 is located on the side of the infrared camera 205. The material properties of the germanium glass window 501 allow infrared light to pass through, but shield visible light and stray infrared interference, specifically for the internal infrared camera 205 to perform infrared imaging detection of the underwater environment. Other sensor devices also have corresponding viewing windows at their front ends to ensure that each sensor acquires the corresponding signals from the water area in front.

[0025] As one embodiment, the multi-sensor device 20 also includes a solid-state lidar 201, a high-speed camera 202, an RGB camera 203, and an event camera 204.

[0026] In other words, the main body shell 10 is equipped with five sensor devices: solid-state lidar 201, high-speed camera 202, RGB camera 203, event camera 204, and infrared camera 205.

[0027] As one embodiment, the main housing 10 is provided with a plurality of mounting bases 101, each mounting base 101 being used to mount each multi-sensor device 20.

[0028] In other words, these sensors are fixed in the inner cavity of the main body shell 10 by the mounting base 101 and integrated in a predetermined layout to achieve synchronous acquisition of multimodal data.

[0029] It should be noted that, as Figure 2 As shown, the five sensor devices are arranged and installed sequentially along the inner sidewall of the main housing 10.

[0030] As one embodiment, the underwater multi-sensor data acquisition device also includes a second cover plate 60, which covers the germanium glass window 501.

[0031] Specifically, such as Figure 4 As shown, the second cover plate 60 is flange-connected to the main body shell 10 and secured with bolts. The second cover plate 60 is made of stainless steel, with the same thickness and strength as the main body shell 10, ensuring underwater pressure resistance. An infrared camera 205 and its supporting structure are installed inside the second cover plate 60: the infrared camera 205 is fixed to the inner surface of the second cover plate 60 near the center, aligned with the germanium glass window 501 at the front end of the main body 10. When disassembling the second cover plate 60, the infrared camera 205 can be removed together from the main body shell 10, facilitating the inspection and replacement of the infrared camera 205 and other internal components.

[0032] As one embodiment, the underwater multi-sensor data acquisition device also includes a mounting bracket 70, which is fixedly installed on the outer shell 10 of the main body.

[0033] In other words, a metal mounting bracket 70 is fixed to the outside of the main body shell 10 by welding or screws, which is used to securely install the underwater multi-sensor data acquisition equipment on the underwater body or platform.

[0034] As an example, the underwater multi-sensor data acquisition device also includes a three-way pagoda-head wiring harness outlet 80, which is welded and sealed onto the main body housing 10.

[0035] In other words, the side wall of the main body housing 10 is provided with three pagoda head wire harness outlets 80, which serve as outlet interfaces for the signal cables of each sensor. The pagoda head wire harness outlets 80 are welded and sealed on the main body housing 10, which can connect to external cables and support quick disassembly and assembly, ensuring that the cable is led out while maintaining the housing seal.

[0036] Specifically, such as Figure 3 As shown, the wire harness outlet uses three trapezoidal tapered pagoda-shaped connectors, used for leading out power lines, data signal lines, and other wire harnesses, respectively. The wire harness outlet is fixed to the outer casing wall by welding. The connector has threads and a lock nut structure on the outside for connecting external waterproof cables and allows for quick assembly and disassembly.

[0037] In summary, the underwater multi-sensor data acquisition device of this application integrates multiple sensors through a stainless steel sealed housing, enabling unified acquisition of underwater multimodal data; the germanium glass window ensures the effective operation of the infrared camera without affecting the data acquisition of other optical sensors; the dual water tank structure combined with waterproof rubber rings improves the sealing reliability of the device; the pagoda-shaped cable harness outlet provides a reliable and quick underwater cable connection solution; and the metal mounting bracket facilitates the fixed installation of the device. This device has a compact structure, is easy to install and maintain, and is suitable for underwater detection, remote sensing monitoring, and other applications requiring multi-sensor collaborative operation.
