Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture engineering technology, specifically to a multifunctional integrated monitoring device for marine aquaculture cages. Background Technology

[0002] As an important part of the global protein supply, marine aquaculture is affected by water quality and aquaculture management technology. In the marine aquaculture environment, monitoring fish and real-time monitoring of water quality parameters are crucial to ensuring healthy fish growth, preventing disease outbreaks, and optimizing feeding strategies. Currently, fish observation in marine HDPE gravity aquaculture cages mainly relies on underwater cameras, while water quality monitoring requires additional multi-parameter water quality monitors. Existing monitoring solutions usually combine underwater cameras and multi-parameter water quality monitors and fix them in a custom-made iron frame, which is then fixed to the aquaculture cage by ropes. However, this combination method has several problems: (1) Weight problem: The combination of the iron frame and multiple independent devices is heavy, increasing the burden on the cage and also increasing the difficulty and risk of operation. (2) Space occupation and interference: Multiple independent devices occupy the limited space inside the cage, increasing the risk of collision or entanglement with the netting and cultured organisms. (3) Cumbersome operation: Each instrument has its own cable, which leads to complicated wiring and requires multiple people to cooperate in the handling and placement operations, increasing labor intensity and time costs. (4) Impact of severe weather: The sea area is often exposed to severe weather such as typhoons. Heavy equipment is easily loosened in strong winds and waves, and may even damage the net cages. (5) Safety issues: The sharp edges of traditional iron frames may hit the net cages in severe weather, causing the netting to break and leading to the escape of farmed fish, increasing the risk of aquaculture losses.

[0003] (6) Difficult maintenance: Due to the weight of the equipment and the complexity of the wiring, daily maintenance and data collection become difficult, requiring multiple people to operate, which affects the frequency and efficiency of monitoring. (7) Data fragmentation: Camera images and water quality data come from different locations and different time points, making it difficult to establish a direct spatial correlation analysis.

[0004] To address the aforementioned issues and improve the efficiency and safety of marine aquaculture, a new type of integrated monitoring device is needed. This device should be able to tightly integrate water quality sensors and underwater cameras, simplify wiring, reduce weight, improve equipment stability and ease of operation, and minimize the impact on fish cages.

[0069] See Figures 1 to 7 This utility model provides a multifunctional integrated monitoring device for marine aquaculture cages, including a protective shell 1, a visual inspection mechanism 2, and a water quality inspection mechanism 3. The protective shell 1 has a sealed cavity, and the visual inspection mechanism 2 is set in the sealed cavity, including a camera 21, a supplementary light 22, and a visual control unit 23. The camera 21 and the supplementary light 22 are both connected to the visual control unit 23. The water quality inspection mechanism 3 has a water quality sensor 31 and a water quality inspection control unit 32. The water quality sensor 31 is fixedly installed on the protective shell 1, and the detection end of the water quality sensor 31 that is in contact with water is located outside the sealed cavity. The water quality inspection control unit 32 is set in the sealed cavity and is connected to the protective shell 1. The protective shell 1 has an external interface 4, which can be used for communication and power connection. The visual control unit 23 is connected to the external interface 4, and the water quality inspection control unit 32 is connected to the external interface 4.

[0070] The main working principle of the multifunctional integrated monitoring device involved in this utility model is as follows: The protective shell 1 serves as the mounting base for the visual inspection mechanism 2 and the water quality detection mechanism 3, providing a sealed cavity for the installation of components such as the visual inspection mechanism 2 and the water quality detection control unit 32 that do not come into contact with seawater. The sealed cavity can ensure internal airtightness through various suitable existing methods, playing a waterproof protection role to ensure the safety of various electronic components for long-term use. The detection end of the water quality sensor 31 is located outside the sealed cavity and comes into contact with seawater during use. During installation, the protective shell 1 of the multifunctional integrated monitoring device can be suspended and placed into the aquaculture cage and connected to the marine aquaculture cage. The multifunctional integrated monitoring device utilizes the external interface 4 to quickly connect to the external cable. The external cable can be a composite cable, which has both signal transmission and power transmission functions. In this way, the visual inspection mechanism 2 and the water quality detection mechanism 3 can communicate and be powered by the external environment through the external interface 4 and a single external cable. The entire device only requires one cable connection, simplifying wiring. During operation, the vision control unit 23 in the vision inspection mechanism 2 is communicatively connected to the camera 21 and the supplementary light 22. It can control the camera 21 to capture images and control the supplementary light 22 to provide supplementary illumination. The image data captured by the camera 21 is transmitted to the vision control unit 23 for data processing and then transmitted out via an external cable. The water quality sensor 31 in the water quality testing mechanism 3 contacts seawater and measures the data, transmitting it to the water quality testing control unit 32 for processing and transmission out via a cable. Furthermore, remote signal transmission can be achieved through the external cable and external interface 4, enabling remote control of the multi-functional integrated monitoring device. This multi-functional integrated monitoring device combines visual monitoring and water quality monitoring functions into one unit. Its integrated installation and use effectively simplify installation and wiring, is portable, occupies little space, minimizes the impact on the net cages, and reduces the risk of collision or entanglement with netting and aquatic organisms.

[0071] See Figures 1 to 7 The present invention will be further described below with reference to specific embodiments:

[0072] In this embodiment, see Figure 1 and Figure 4As a preferred design, external interface 4 is used for signal transmission and power supply. It adopts a standard interface for easy integration or interfacing with third-party applications. Specifically, it can use an interface compatible with a 4-electrical-8-optical composite cable. The external cable is a 4-electrical-8-optical composite cable. This enables the power supply and external communication of the multi-functional integrated monitoring device. Through the wired connection of the external cable, stable high-bandwidth Ethernet / RS485 data transmission is provided. In this application, the power supply for the visual inspection mechanism 2 and the water quality testing mechanism 3 can be directly transmitted from external interface 4 to the visual control unit 23 and the water quality testing control unit 32. That is, the connection between the visual control unit 23 and external interface 4, and the connection between the water quality testing control unit 32 and external interface 4, both include communication and circuit connections, thus combining communication and power supply functions. The vision control unit 23 then supplies power to the camera 21 and the supplementary light 22, while the water quality detection control unit 32 supplies power to the water quality sensor 31. This means the connection between the vision control unit 23 and the camera 21 and the supplementary light 22 includes both communication and electrical connections, and the connection between the water quality detection control unit 32 and the water quality sensor 31 includes both communication and electrical connections. Furthermore, in other embodiments, in certain situations, a built-in battery can be used to power the vision detection mechanism 2 and the water quality detection mechanism 3. Here, the battery can be directly connected to the vision control unit 23 and the water quality detection control unit 32 to provide power. The battery is connected to the external interface 4 via a circuit, and is externally connected (e.g., a solar panel) to charge the battery.

[0073] In this embodiment, see Figure 2 , Figure 4 , Figure 6 and Figure 7As a preferred design, the protective housing 1 includes a first housing 11 and a second housing 12, with a detachable connection structure 13 between the first housing 11 and the second housing 12 for fixed connection or separation; the sealed accommodating cavity includes a first accommodating chamber located in the first housing 11 and a second accommodating chamber located in the second housing 12, with the visual inspection mechanism 2 disposed in the first accommodating chamber; the water quality sensor 31 of the water quality detection mechanism 3 is installed in the second housing 12, and the water quality detection control unit 32 is disposed in the second accommodating chamber; a quick-connect connection mechanism 5 is provided between the first housing 11 and the second housing 12, the quick-connect connection mechanism 5 including a first quick-connect interface 51 and a second quick-connect interface 52 respectively disposed on the first housing 11 and the second housing 12, the first quick-connect interface 51 and the second quick-connect interface 52 being able to be plugged into or separated from each other; an external interface 4 is disposed on the first housing 11, at which time the water quality detection control unit 32 is connected to the second quick-connect interface 52 through a line, enabling communication and power transmission, and the first quick-connect interface 51 is connected to the external interface 4 through a line, enabling communication and power transmission. This design allows the first housing 11 and the visual inspection mechanism 2 mounted thereon to be considered as a single unit, namely the visual inspection component, while the second housing 12 and the water quality inspection mechanism 3 mounted thereon can be considered as a single unit, namely the water quality inspection component. These two components can be quickly connected and disconnected via the detachable connection structure 13, and the wiring can be quickly connected or disconnected via the quick-connect mechanism 5. This allows for quick replacement or assembly of the visual inspection component or the water quality inspection component based on actual damage or operational needs, without requiring a complete replacement, making it more flexible and convenient. When the visual inspection component and the water quality inspection component are assembled, the connection path between the water quality inspection mechanism 3 and the outside is: water quality inspection control unit 32—second quick-connect interface 52—first quick-connect interface 51—external interface 4—external cable. The circuit connection path of the visual control unit 23 is: visual control unit 23—external interface 4—external cable. Of course, in other embodiments, the external interface 4 can also be located on the second housing 12. In this case, the vision control unit 23 is connected to the first quick-connect interface 51 via a line, and the second quick-connect interface 52 is connected to the external interface 4 via a line. The principle is the same in both cases. In this case, the circuit connection path between the vision detection mechanism 2 and the outside is: vision control unit 23—first quick-connect interface 51—second quick-connect interface 52—external interface 4—external cable. The circuit connection path of the water quality control unit is: water quality detection control unit 32—external interface 4—external cable. When the water quality detection control unit 32, vision control unit 23, external interface 4, first quick-connect interface 51, and second quick-connect interface 52 are connected to each other via lines, the communication lines can be fiber optic signal lines or wire signal lines.

[0074] In this embodiment, the first quick-connect interface 51 and the second quick-connect interface 52 of the quick-connect mechanism 5 also have communication and power transmission functions. A composite interface with 2 electrical and 2 optical functions can be used. Through the conversion between the first quick-connect interface 51 and the second quick-connect interface 52, communication connection between the water quality detection and control unit 32 and the external interface 4 can be realized.

[0075] In this embodiment, see Figure 1 , Figure 2 and Figure 6 As a preferred design, the detachable connection structure 13 further includes a connecting tube 131, a fastening sleeve 132, and a sealing gasket 133. The connecting tube 131 is fixed on the first housing 11, and the first quick-connect interface 51 is located in the connecting tube 131. The second housing 12 has a plug portion 1211 that is inserted into the connecting tube 131. The second quick-connect interface 52 is disposed on the plug portion 1211. The sealing gasket 133 is fixed on the outer surface of the plug portion 1211. The fastening sleeve 132 is fitted over the plug portion 1211, and a pressing surface 1321 is provided in the inner hole of the fastening sleeve 132. The fastening sleeve 132 is fitted over the connecting tube 131 and the two are fixedly connected, so that the pressing surface 1321 presses the sealing gasket 133 against the end face of the connecting tube 131, and the first quick-connect interface 51 and the second quick-connect interface 52 are connected to each other. Preferably, the fastening sleeve 132 and the connecting pipe 131 are connected by a thread, that is, the fastening sleeve 132 is provided with an internal thread and the connecting pipe 131 is provided with an external thread. In this way, the fastening sleeve 132 can be easily fixedly connected to the connecting pipe 131 and can be easily disassembled. Other suitable detachable methods can also be used to connect the fastening sleeve 132 and the connecting pipe 131. With the above design, during installation, simply insert the plug portion 1211 of the second housing 12 into the connection hole. At this time, the first quick-connect interface 51 and the second quick-connect interface 52 are quickly connected. Then, rotate the fastening sleeve 132 to screw it onto the connecting tube 131, and press the pressing surface 1321 against the sealing gasket 133 on the plug portion 1211. This makes the sealing gasket 133 tightly pressed against the end face of the connecting tube 131, thus fixing the first housing 11 and the second housing 12 together and achieving a sealing effect. This creates a sealed space inside the connecting tube 131, preventing seawater from entering and ensuring the waterproofness of the first quick-connect interface 51 and the second quick-connect interface 52 during operation.

[0076] See Figure 1 and Figure 5In this embodiment, as a preferred design, the second housing 12 of the protective housing 1 is further provided with a water inlet chamber. The detection end of the water quality sensor 31 is located in the water inlet chamber, which is used to protect the water quality sensor 31 and allow seawater to enter without affecting the normal operation of the water quality sensor 31. Specifically, the second housing 12 includes a second housing body 121 for connection with the first housing 11, and a water inlet protection tube 122 screwed and fixed to the second housing body 121. The second quick-connect interface 52 and the water quality sensor 31 are both mounted on the second housing body 121. The water inlet protection tube 122 can be detached from the second housing body 121, that is, the water inlet protection tube 122 can be detached from the protective housing 1 when the device is assembled. The water inlet protection tube 122 is provided with a water inlet hole 1221 communicating with its inner cavity, and the inner cavity of the water inlet protection tube 122 constitutes the water inlet chamber. In this manner, before installing the water quality sensor 31, the inlet protection tube 122 is first removed to facilitate the installation of the water quality sensor 31 onto the second housing body 121. Then, the inlet protection tube 122 is fitted over the water quality sensor 31 and screwed into the second housing body 121, ensuring that the water quality sensor 31 is located within the inlet protection tube 122, thus protecting it. Seawater can enter the inlet chamber within the inlet protection tube 122 through the inlet hole 1221, contacting the detection end of the water quality sensor 31 without affecting its normal detection operation.

[0077] In this embodiment, see Figure 1 , Figure 3 and Figure 4 As a preferred design, the visual inspection mechanism 2 employs a binocular camera 21. The binocular camera 21 uses a 5-megapixel 2 / 3″ independent imaging CMOS image sensor 212, equipped with an underwater-specific wide-angle lens 211 and an image acquisition card 213, achieving high-precision imaging. The supplementary lighting 22 uses multiple LEDs to ensure effective illumination. The visual control unit 23 performs functions such as image data collection, processing, signal transmission, and control. Specifically, it includes a control processing module 231, a storage medium 233, and a power and signal conversion configuration module 232. The control processing module 231 is used for image data collection... The image acquisition card 213 collects and processes image data, storage medium 233 stores the image data, and power and signal conversion configuration module 232 is used for signal conversion and transmission, as well as power conversion and transmission. When the external interface 4 is connected to a power source via an external cable, the power and signal conversion configuration module 232 can supply power to the entire vision control unit 23, the supplementary light 22, and the camera 21. The acquired and processed data is transmitted out through the power and signal conversion configuration module 232. The vision control unit 23 can also adopt other existing suitable structures that can achieve the above-mentioned functions.

[0078] In this embodiment, see Figure 4 As a preferred design, the first housing 11 is provided with a transparent window, which can be made of sapphire crystal. The lens 211 of the camera 21 faces the transparent window and takes pictures outward through it. The supplementary light 22 faces the transparent window, and its light shines out through the transparent window. The transparent window ensures that the camera 21 and the supplementary light 22 are completely located within the first receiving chamber of the first housing 11, ensuring watertightness. In other embodiments, without a transparent window, the lens 211 of the camera 21 and the supplementary light 22 can be embedded in the outer wall of the first housing 11, ensuring the watertightness of the embedding area to prevent seawater from entering the first receiving chamber, thus ensuring the watertightness of the first receiving chamber. Preferably, the waterproof rating of the first housing 11 reaches IP68, adapting to various marine environments.

[0079] In this embodiment, see Figure 1 and Figure 5 As a preferred design, there are multiple water quality sensors 31, each of which can be used to measure one or more parameters. Preferably, multiple water quality sensors 31 are used to measure water quality parameters such as dissolved oxygen, temperature, conductivity, pH, turbidity, chlorophyll a, and cyanobacteria / algae density. The water quality sensors 31 can all adopt existing mature design structures, and their specific structural principles are not limited in this application.

[0080] In this embodiment, see Figure 1 and Figure 7 As a preferred design, the water quality detection and control unit 32 includes a water quality signal acquisition module 321, a control processing module 322, a buffer module 323, and a communication module 324. The water quality signal acquisition module 321 acquires data signals from each water quality sensor 31, which are then processed and calculated by the control processing module 322. The buffer module 323 buffers the data, and the communication module 324 transmits data and signals to external systems. Alternatively, the water quality detection and control unit 32 can employ other suitable structures that achieve the aforementioned functions. The water quality detection and control unit 32 is housed in the second receiving chamber within the second housing body 121 of the second housing 12. The second housing body 121 preferably has a waterproof rating of IP68 to adapt to various marine environments.

[0081] In this embodiment, see Figure 1 and Figure 7As a preferred design, the multifunctional integrated monitoring device also includes a cleaning mechanism 6 installed in the second housing 12, which, during normal use, is located in the inlet protection pipe 122 along with the water quality sensors 31. The cleaning mechanism 6 includes a cleaning brush 61 and a cleaning blocking assembly. The cleaning blocking assembly drives the cleaning brush 61 to move, causing it to contact and brush the detection ends of each water quality sensor 31. Furthermore, the multiple water quality sensors 31 are arranged in a ring array. The cleaning blocking assembly includes a rotating shaft 62 and a motor 63 connected to the rotating shaft 62. The cleaning brush 61 is fixed on the rotating shaft 62 and contacts the detection ends of the water quality sensors 31. The rotating shaft 62 coincides with the center of the ring array of water quality sensors 31. The motor 63 drives the rotating shaft 62 to rotate, causing the cleaning brush 61 to rotate. The movement path of the cleaning brush 61 passes through the detection ends of each water quality sensor 31, thereby cleaning the detection ends of each water quality sensor 31, removing any adhering substances in a timely manner, and ensuring the normal detection operation of the water quality sensors 31. In other embodiments, the multiple water quality sensors 31 can also be arranged in a straight line or other arrangements, and the cleaning blocking component can also adopt other suitable structures. The cleaning brush 61 can be driven to move along a trajectory that matches the arrangement of the water quality sensors 31.

[0082] In this embodiment, see Figure 1 and Figure 7 As a preferred design, the multi-functional integrated monitoring device also includes a suspension component 7 fixed to the protective housing 1. The suspension component 7 can specifically be a hook and is fixed to the first housing 11. The top of the first housing 11 is provided with a perforated disc, which is connected to the suspension component 7. The multi-functional integrated monitoring device is hoisted into the aquaculture net cage through the suspension component 7, and the device position is fixed by the suspension component 7, which facilitates rapid deployment and retrieval, reducing operation time and labor intensity.

[0083] In this embodiment, the protective shell 1 is made of titanium alloy, which is high in strength, lightweight, and resistant to seawater corrosion, and can be used for long-term deployment in marine monitoring and aquaculture.

[0084] As can be seen from the above, the multifunctional integrated monitoring device of this utility model has the following beneficial effects:

[0085] 1. Integrating visual and multiple water quality detection functions, it is easy to install and use. Only one external cable is needed to realize the signal transmission and power connection between the device and the outside world, which can effectively simplify installation and wiring. It is portable and the entire device structure can be compact, small in size, occupy little space, and have little impact on the net cage, effectively reducing the risk of collision or entanglement with the net and aquatic organisms, thus improving safety. Moreover, the image data and water quality data come from the same location and the same time point, which can establish a direct and spatially corresponding correlation analysis.

[0086] 2. The protective housing 1 is provided with a separable first housing 11 and a second housing 12, which are used for the installation of the visual inspection mechanism 2 and the water quality inspection mechanism 3 respectively, thereby forming a visual monitoring part and a water quality inspection part that can be freely disassembled and assembled. One part can be flexibly maintained and replaced according to actual needs, which is convenient to use and maintain and reduces maintenance costs.
