Description

Technical Field

[0001] This application relates to the field of hydrological observation and data transmission technology, and in particular to a bottom-mounted hydrological observation real-time transmission system. Background Technology

[0002] Ocean hydrological observation plays a crucial role in marine research. Long-term ocean hydrological data are key to confirming the characteristics of elements such as waves, currents, salinity, and temperature, as well as their seasonal variations. This data helps researchers better understand the marine environment and provides important evidence for many aspects, including marine resource development, marine engineering construction, marine environmental protection, marine disaster early warning, and even military security needs. As marine research continues to deepen, the requirements for the accuracy and completeness of ocean hydrological observation data are becoming increasingly stringent.

[0003] Currently, buoy observation equipment and seabed observation equipment are mainly used to obtain marine hydrological data. Buoy observation equipment is set on the water surface and has the advantage of being able to transmit signals in real time, allowing for the real-time transmission of some observation data. Seabed observation equipment, on the other hand, is placed on the seabed for data observation. It typically uses acoustic transducers to convert electrical signals into sound waves, which are then transmitted through the water and bounced back to the seabed. The data is stored within the seabed observation equipment.

[0004] However, existing hydrological observation equipment has significant shortcomings when conducting long-term (unattended) observations. Buoy observation equipment is easily damaged by extreme weather and sea conditions, fishing vessels, etc., and legal buoys require registration with the maritime authorities, which is cumbersome and expensive. While bottom-mounted observation equipment is low-cost and quick to deploy, it cannot detect data loss in a timely manner without real-time data transmission. Severe weather or fishing vessel anchors can disturb the instrument's attitude, leading to data anomalies and instrument damage. Regularly retrieving and checking the seabed instruments cannot guarantee the continuity and stability of observation data, and it is impossible to know if the instrument is damaged or the data is invalid until the instrument is retrieved and the long-sequence data loss is discovered, which is then irreversible. Utility Model Content

[0005] To address the issue of low continuity and stability of observation data from existing hydrological observation equipment, this application provides a bottom-mounted hydrological observation real-time transmission system.

[0006] This application provides a bottom-mounted hydrological observation real-time transmission system, which adopts the following technical solution: A bottom-mounted hydrological observation real-time transmission system includes a user terminal, a data acquisition device, a data transmission terminal, and a power module mounted on a semi-submersible marine structure. The data acquisition device is mounted on the seabed, and a protective cover is installed on the top of the exposed pile of the semi-submersible marine structure. The power module is housed inside the protective cover. The power module is electrically connected to the data acquisition device and the data transmission terminal. The data acquisition device and the data transmission terminal are connected via a cable. The data transmission terminal is communicatively connected to the user terminal. The cable is covered with a protective sleeve, and a counterweight is detachably fixed to the cable to secure it to the side of the semi-submersible marine structure.

[0007] By adopting the above technical solution, the power module can power the system equipment, enabling long-term observation. The data acquisition device observes hydrological data in real time and transmits the observation data in real time through a cable connection to the data transmission terminal. This allows the data transmission terminal to transmit the observation data to the user terminal in real time, thus enabling timely detection in case of force majeure damage to the instrument and shortening the data loss time. The protective cover installed on the semi-submersible marine structure can protect the power module, preventing damage to the power module from affecting the power supply of the entire system. At the same time, using counterweights to fix the cable and covering the cable with a protective sleeve can enhance the cable's anti-interference ability in the marine environment, preventing damage from waves, fishing nets, or wear on the seabed. This lays the foundation for continuous and stable data transmission, thereby improving the continuity and stability of the system's observation data.

[0008] Preferably, the data acquisition device includes a base set on the seabed and a current meter fixed on the base. The current meter is electrically connected to a power module, and the current meter is connected to a data transmission terminal via a cable. An anti-pollution device is also fixed on the base, and the anti-pollution device is electrically connected to the power module.

[0009] By adopting the above technical solutions, the base, placed on the seabed, provides a stable support foundation for the current meter and the anti-pollution device, allowing them to operate steadily on the seabed. The power module provides power to the current meter, enabling it to accurately collect oceanographic data such as current velocity for extended periods without battery replacement. The collected data is then transmitted in real time to the data transmission terminal via cable, allowing the terminal to transmit the observation data to the user terminal in real time. The anti-pollution device, fixed to the base, effectively prevents fouling organisms from adhering to the surface of the current meter and other equipment, thus ensuring normal instrument operation and improving the continuity and stability of the observation data.

[0010] Preferably, it also includes a solar panel for charging the power module. A support rod is fixed to the top of the pile of the semi-submersible marine structure that protrudes above the sea surface, and a horizontal mounting plate is fixed to the support rod. The solar panel is fixed to the side of the horizontal mounting plate away from the semi-submersible marine structure, and the solar panel is electrically connected to the power module.

[0011] By adopting the above technical solution, the support rods and horizontal mounting plates on the semi-submersible marine structure provide a support foundation for the solar panels. The solar panels charge the power modules, which can provide a continuous and stable power supply for the system, avoid data loss due to power outages, and improve the integrity and reliability of the system's observation data.

[0012] Preferably, it also includes a mooring release and recovery device; the mooring release and recovery device includes a surface control unit and an underwater recovery unit, and the surface control unit and the underwater recovery unit are connected by underwater wireless communication via a hydrophone, and a cable is provided between the underwater recovery unit and the data acquisition device, and a fixed anchor embedded in the seabed is provided on the cable.

[0013] By adopting the above technical solution, when the equipment needs maintenance or is damaged, the surface control unit of the mooring release and recovery device can send a recovery command signal to the underwater recovery unit. Upon receiving the command signal, the underwater recovery unit of the mooring release and recovery device can release a buoy to recover all the equipment on the seabed, so as to carry out equipment maintenance and data export. This reduces the potential losses caused by retrieving data acquisition equipment from the cable (which may snag the cable or drag the instrument), and improves the maintainability of the system. Furthermore, the underwater recovery unit of the mooring release and recovery device is connected to the data acquisition device by a cable, and a fixed anchor embedded in the seabed is set on the cable to further secure the data acquisition device and prevent it from being damaged and causing data loss.

[0014] Preferably, a safety rope is installed between the data acquisition device and the top of the pile of the semi-submersible marine structure that protrudes above the sea surface, and a number of counterweight stones are installed on the cable between the data acquisition device and the data transmission terminal to fix the cable to the seabed.

[0015] By adopting the above technical solution, a safety rope is installed between the data acquisition device and the top of the semi-submersible marine structure's exposed pile. This strengthens the connection between the data acquisition device and the semi-submersible marine structure, preventing the entire data acquisition device from being dragged away by the anchor. At the same time, several counterweight stones are installed on the cable between the data acquisition device and the data transmission terminal to fix the cable to the seabed, preventing the cable from shifting or being damaged by external forces. This further improves the stability of the connection between the data acquisition device and the data transmission terminal, thereby ensuring the continuity and stability of the observation data transmission.

[0016] Preferably, the device also includes a camera and an audible and visual alarm, both of which are fixed on the side of the horizontal mounting plate away from the solar panel. The camera and the audible and visual alarm are electrically connected to the power module, the camera is communicatively connected to the data transmission terminal, and the camera is electrically connected to the audible and visual alarm.

[0017] By adopting the above technical solution, the camera can monitor the surrounding environment of the system in real time. When an abnormal situation is detected, the camera can process the image data to generate alarm information and transmit the image and alarm information to the data transmission terminal in real time. The data transmission terminal can then transmit the image and alarm information to the user terminal in real time, thereby reminding the user to check for abnormal situations in a timely manner. At the same time, when the camera detects an abnormal situation, it can control the audible and visual alarm to emit audible and visual signals for warning, which can effectively improve the system's response capability to emergencies, ensure that relevant personnel are aware of the surrounding situation of the system in a timely manner, and further guarantee the stable operation of the system and the continuous and stable transmission of data.

[0018] Preferably, a bend-resistant sleeve is provided at the corner of the top of the pile of the semi-submersible marine structure that is exposed above the sea surface, and the cable passes through the bend-resistant sleeve and is connected to the data transmission terminal.

[0019] By adopting the above technical solution, the anti-bend sleeve can prevent the cable from bending and abrading at the top corner of the semi-submersible marine structure, ensuring the integrity of the cable and the stability of data transmission, thereby ensuring that the observation data can be stably transmitted from the data acquisition device to the data transmission terminal.

[0020] Preferably, the counterweight and the cable are detachably fixed together by a cable tie. The counterweight has a clearance groove for placing the cable and an annular groove for preventing the cable tie from shifting.

[0021] By adopting the above technical solution, the clearance groove facilitates the positioning and placement of the cable and the counterweight, and the annular groove can prevent the binding strap from shifting. The clearance groove, the annular groove and the binding strap work together to achieve detachable fixing of the counterweight and the cable, which not only ensures the stable fixing of the counterweight to the cable, but also allows for flexible adjustment of the number or position of the counterweight according to the marine environment, improving the convenience of installation and maintenance, while ensuring the stability of the cable during data transmission.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Using solar panels to charge the power module provides a continuous and stable power supply to the system, preventing data loss due to power outages. The underwater data acquisition device is connected to the data transmission terminal above the water surface via a cable, and the data transmission terminal then transmits data to the user terminal in real time. This allows for timely detection of damage to the instrument due to force majeure, thus shortening the duration of data loss. At the same time, using counterweights to fix the cable and covering the cable with a protective sleeve enhances the cable's anti-interference ability in the marine environment, preventing damage from waves, fishing nets, and abrasion on the seabed, thereby improving the continuity and stability of the system's observation data. 2. Set up a mooring release and recovery device and connect it to the data acquisition device to recover the data acquisition device. When the underwater recovery unit of the mooring release and recovery device receives the recovery command signal from the nearby surface control unit, it can release the float to recover all the equipment on the seabed, so as to carry out equipment maintenance and data export, reduce the loss caused by hooking the equipment from the cable end, reduce the risk of equipment damage, and improve the maintainability of the system. 3. The camera can monitor the surrounding environment of the system in real time and process abnormal image data to generate alarm information. The image and alarm information are then transmitted to the data transmission terminal in real time, so that the data transmission terminal can transmit the image and alarm information to the user terminal in real time, thereby reminding the user to check for abnormal situations in time. At the same time, the camera can control the sound and light alarm to emit sound and light signals for warning, further ensuring the stable operation of the system and the continuous and stable transmission of data.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0026] This application discloses a bottom-mounted hydrological observation real-time transmission system.

[0027] Reference Figure 1 and Figure 3 A bottom-mounted hydrological observation real-time transmission system includes a user terminal 3 and a data acquisition device 1, a data transmission terminal 2, a power module 4, a solar panel 5, a camera 6, an audible and visual alarm 7, and a mooring release and recovery device 8, all mounted on a semi-submersible marine structure. The data acquisition device 1 is embedded in the seabed by its own weight. A protective cover 9 and a support rod 10 are fixed to the top of the exposed pile of the semi-submersible marine structure. A horizontal mounting plate 101 is fixed to the end of the support rod 10 away from the semi-submersible marine structure. The power module 4 is located inside the protective cover 9. The solar panel 5 is fixed to the side of the horizontal mounting plate 101 away from the semi-submersible marine structure. The camera 6 and the audible and visual alarm 7 are also mounted on the semi-submersible marine structure. The underwater mooring release and recovery device 8 is fixed on the side of the horizontal mounting plate 101 away from the solar panel 5. The device includes a surface control unit 81 and an underwater recovery unit 82. The surface control unit 81 and the underwater recovery unit 82 are connected to each other via underwater wireless communication through a hydrophone. The underwater recovery unit 82 is connected to the data acquisition device 1 by a cable 13. A fixed anchor 131 embedded in the seabed is fixed on the cable 13. In this embodiment, there are two fixed anchors 131, which are located on both sides of the underwater recovery unit 82. The fixed anchor 131 closer to the underwater recovery unit 82 is a 100kg anchor, and the fixed anchor 131 farther away from the underwater recovery unit 82 is a 50kg anchor. Reference Figure 1 and Figure 3The solar panel 5 is electrically connected to the power module 4, which is electrically connected to the data acquisition device 1, the data transmission terminal 2, the camera 6, and the audible and visual alarm 7. The camera 6 is communicatively connected to the data transmission terminal 2 and the audible and visual alarm 7. The data acquisition device 1 and the data transmission terminal 2 are connected via a cable 14. The data transmission terminal 2 and the underwater glider release and recovery device 8 are communicatively connected to the user terminal 3. In this embodiment, the user terminal 3 may include a smart interactive flat panel, mobile phone, tablet computer, laptop computer, desktop computer, all-in-one computer, vehicle multimedia, server, or workstation. The data transmission terminal 2 transmits data to the onshore user terminal 3 via 4G+BeiDou communication. 4G is the basic communication method. When the 4G signal cannot transmit data for more than 24 hours, BeiDou communication will be activated to transmit the most important data to the user terminal 3. The cable 14 is covered with a protective sleeve, and a counterweight 15 is detachably fixed to the cable 14 for fixing the cable 14 to the side of the semi-submersible marine structure.

[0028] In practical use, the support rod 10 and horizontal mounting plate 101 on the semi-submersible marine structure provide a supporting foundation for the solar panel 5. The solar panel 5 receives sunlight and converts it into electrical energy, which is stored in the power module 4 on the semi-submersible marine structure. The power module 4 stores enough electricity to power the data acquisition device 1, data transmission terminal 2, camera 6, and audible and visual alarm 7 even under 15 consecutive days of cloudy and rainy weather in the current sea area. At the same time, the power module 4 transmits voltage data to the user terminal 3 via the data transmission terminal 2 so that the user terminal 3 can check the power supply status of the power module 4 and avoid data loss due to power outages. The data acquisition device 1 conducts real-time observation on the seabed. Hydrological data is transmitted in real time via cable 14 to data transmission terminal 2. Then, data transmission terminal 2 transmits the observation data to user terminal 3 in real time, so that the loss of data can be detected in time when the instrument is damaged by force majeure. The protective cover 9 on the semi-submersible marine structure provides protection for the power module 4, preventing damage to the power module 4 from sun exposure, heavy rain, and waves, which would affect the power supply of the entire system. The counterweight 15 fixes the cable 14 to prevent it from being damaged by waves, fishing nets, or worn on the seabed. At the same time, the cable 14 is covered with a protective sleeve to enhance the anti-interference ability of the cable 14 in the marine environment, laying the foundation for continuous and stable data transmission. Camera 6 monitors the surrounding environment of the system in real time and transmits the images to user terminal 3 through data transmission terminal 2. When an abnormal situation is detected, camera 6 processes the image data to generate alarm information and transmits both the image and alarm information to user terminal 3 through data transmission terminal 2 to remind the user to check the abnormal situation in time. At the same time, camera 6 controls the sound and light alarm 7 to emit sound and light signals to warn relevant personnel to be aware of the surrounding situation of the system in time, and to ensure the stable operation of the system and the continuous and stable transmission of data. A fixed anchor 131 is installed on the cable 13 between the underwater recovery unit 82 of the mooring release and recovery device 8 and the data acquisition device 1. The fixed anchor 131 uses its own weight to drive the anchor claws into the seabed, further securing the data acquisition device 1 and preventing damage that could lead to data loss. When the user terminal 3 experiences an interruption in receiving data, the surface control unit 81 of the mooring release and recovery device 8 moves closer to the area where the underwater recovery unit 82 is located. When the surface control unit 81 moves within 300 meters, it can send a recovery command signal to the underwater recovery unit 82. Upon receiving the command signal, the underwater recovery unit 82 will release a buoy to recover all the equipment on the seabed, so that the equipment can be inspected and the data can be exported. This reduces the potential losses caused by retrieving the data acquisition equipment from the cable 14 and improves the maintainability of the system.

[0029] Reference Figure 1 , Figure 2 as well as Figure 3 A safety rope 16 is connected between the data acquisition device 1 and the top of the semi-submersible marine structure's exposed pile. Several counterweight stones 17 are fixed to the cable 14 between the data acquisition device 1 and the data transmission terminal 2 via ropes to secure the cable 14 to the seabed. In this embodiment, the safety rope 16 is a steel cable. Several clamps 19 are installed on the semi-submersible marine structure to secure the downward-extending cable 14 and the safety rope 16. The cable 13 between the underwater recovery unit 82 of the mooring release and recovery device 8 and the data acquisition device 1 is connected to the same... The system is fixed with counterweight stones 17. In actual use, the safety rope 16 strengthens the connection between the data acquisition device 1 and the semi-submersible marine structure, preventing the entire data acquisition device 1 from being dragged away by the anchor. The clamp 19 prevents the cable 14 and safety rope 16 from being damaged by continuous impacts on the semi-submersible marine structure. At the same time, the counterweight stones 17 fixed on the cable 14 and cable 13 press and fix the cable 14 and cable 13 underwater to the seabed, preventing the cable 14 and cable 13 from shifting or being damaged by external forces, thereby ensuring the continuity and stability of the system's observation data.

[0030] Reference Figure 1 and Figure 4The counterweight 15 is detachably fixed to the cable 14 by a cable tie. The counterweight 15 has a clearance groove 151 for placing the cable 14 and an annular groove 152 for preventing the cable tie from shifting. In this embodiment, four counterweights 15 are provided, and the weight of any one of the counterweights 15 is 50 kg. In actual use, the cable tie enables detachable fixing, allowing the number or position of the counterweights 15 to be flexibly adjusted according to the marine environment, improving the convenience of installation and maintenance. The clearance groove 151 facilitates the positioning of the cable 14 under the counterweight 15 and prevents the counterweight 15 from pressing against and damaging the cable 14. The annular groove 152 prevents the cable tie from shifting, thereby ensuring that the counterweight 15 and the cable 14 are firmly fixed, and thus ensuring the stability of the cable 14 during data transmission.

[0031] Reference Figure 1 and Figure 3 The data acquisition device 1 includes a base 11 embedded in the seabed by its own weight and a current meter 12 fixed on the base 11. The current meter 12 is electrically connected to the power module 4, and the current meter 12 is connected to the data transmission terminal 2 through a cable 14. An anti-pollution device 111 is also fixed on the base 11, and the anti-pollution device 111 is electrically connected to the power module 4. In this embodiment, the current meter 12 is a "Langlong" acoustic wave profile current meter 12, and the anti-pollution device 111 is an optical anti-biocontamination device.

[0032] In practical use, the base 11 is embedded in the seabed by its own weight, providing a stable support foundation for the current meter 12 and the anti-pollution device 111. The current meter 12 accurately collects data such as the current velocity of the ocean and transmits the observation data, the internal voltage of the instrument, the voltage input to the instrument from the power module 4, and the attitude data of the instrument to the data transmission terminal 2 via the cable 14. The data transmission terminal 2 then transmits the data to the user terminal 3 in real time, so that the user terminal 3 can view the observation data and the status of the instrument operation. The anti-pollution device 111 is fixed on the base 11, effectively preventing fouling organisms in the marine environment from adhering to the surface of the current meter 12 and other equipment, thereby affecting the normal observation of the instrument, ensuring the normal operation of the equipment, and thus improving the continuity and stability of the observation data.

[0033] Reference Figure 1A bend-resistant sleeve 18 is fixed at the corner of the top of the pile of the semi-submersible marine structure that protrudes above the sea surface. The cable 14 passes through the bend-resistant sleeve 18 and is connected to the data transmission terminal 2. In this embodiment, the bend-resistant sleeve 18 is arc-shaped. In actual use, the cable 14 passes through the bend-resistant sleeve 18 and is connected to the data transmission terminal 2. This can prevent the cable 14 from bending and wearing at the corner of the top of the semi-submersible marine structure after long-term use, thereby ensuring the integrity of the cable 14 and the stability of data transmission, and thus ensuring that the observation data can be stably transmitted from the data acquisition device 1 to the data transmission terminal 2.

[0034] The implementation principle of this application embodiment is as follows: The power module 4 is powered by the solar panel 5 and stores electrical energy to continuously power the entire system. At the same time, the power module 4 transmits voltage data to the user terminal 3, so that the user terminal 3 can check the power supply status of the power module 4 and avoid data loss due to power interruption. The base 11 in the data acquisition device 1 is embedded and fixed on the seabed by its own gravity, providing stable support for the current meter 12 (using the "Langlong" acoustic wave profile current meter 12) and the anti-pollution device 111 (using an optical anti-biofouling device). The current meter 12 accurately collects data such as the current velocity of the ocean hydrology, and transmits the observation data, the internal voltage of the instrument, the voltage input to the instrument from the power module 4, and the attitude data of the instrument to the data transmission terminal 2 through the cable 14. Then, the data transmission terminal 2 transmits the data to the user terminal 3 in real time, so that the user terminal 3 can check the observation data and the instrument operation status. The anti-pollution device 111 prevents fouling organisms in the marine environment from attaching to the surface of the current meter 12 and other equipment, thereby affecting the normal observation of the instrument, ensuring the normal operation of the equipment, and improving the continuity and stability of data. Camera 6 monitors the surrounding environment in real time. When an anomaly is detected, it controls the audible and visual alarm 7 to issue an audible and visual signal for warning. At the same time, it transmits the image and the alarm information generated after image processing to the user terminal 3, so that relevant personnel can grasp the situation in time and ensure the stable operation of the system. The underwater mooring release and recovery device 8 includes a surface control unit 81 and an underwater recovery unit 82. Fixed anchors 131 (50kg and 100kg respectively) are set on the cables 13 on both sides of the underwater recovery unit 82. Each fixed anchor 131 uses its own weight to drive the anchor claw into the seabed to further fix the data acquisition device 1 and prevent it from being damaged and causing data loss. When the user terminal 3 is interrupted in receiving data, the surface control unit 81 can approach the area where the underwater recovery unit 82 is located and send a recovery command signal to the underwater recovery unit 82 to trigger it to release the float to recover the underwater equipment, so as to inspect the equipment and export the data, reducing the possible loss caused by retrieving the data acquisition equipment from the cable 14. The cable 14 is wrapped with a protective sleeve to enhance its anti-interference capability. At the same time, the anti-bending sleeve 18 can prevent the cable 14 from bending and wearing at the corners of the semi-submersible marine structure, ensuring the integrity of the cable 14. The counterweight 15 is detachably fixed to the cable 14 by a binding strap. The number and position of the counterweight 15 can be flexibly adjusted according to actual needs, improving the convenience of installation and maintenance. The clearance groove 151 on the counterweight 15 facilitates the positioning of the cable 14 and prevents damage to the cable 14, while the annular groove 152 can prevent the binding strap from shifting, thus ensuring that the counterweight 15 and the cable 14 are firmly fixed. The safety rope 16 strengthens the connection between the data acquisition device 1 and the semi-submersible marine structure, preventing the entire data acquisition device 1 from being dragged away by the anchor. At the same time, the counterweight stone 17 presses and fixes the cable 14 and cable 13 underwater, which can effectively prevent displacement or damage caused by external forces and ensure stable data transmission. The whole system achieves continuous, stable and reliable observation and real-time transmission of hydrological data through closed-loop cooperation of acquisition, power supply, transmission, monitoring, fixing and recovery.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
