Description

[0002] The research, development and utilization of the ocean cannot be separated from a variety of marine instruments and equipment. Among them, the seabed-based monitoring system is an important type of marine instrument and equipment. As an underwater platform, the seabed-based monitoring device can be equipped with various sensors for monitoring according to the needs of the mission. Existing seabed-based monitoring devices, when recovered after completing monitoring tasks, directly break the float from the platform base, using the float to lift the monitoring instruments. As a result, the upper surface of the float forms a large trapezoidal structure during ascent. While rising in the water, the large contact area still creates resistance, making it difficult to reduce resistance and buoyancy. This reduces the effectiveness of the recovery process and affects the convenience of increasing buoyancy and reducing resistance during recovery of the seabed-based monitoring device. Therefore, this utility model proposes a new seabed-based monitoring device. Utility Model Content

The large contact area still has a certain resistance when rising in the water, which makes it difficult to reduce the resistance and reduce its buoyancy, thereby reducing the rising effect during recovery.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 6 This utility model provides a technical solution: a seabed-based monitoring device, including a platform base 101. A main float 102 is disposed on the upper surface of the platform base 101, and a float frame 107 is fixed to the bottom end of the main float 102. The float frame 107 matches the structure of the upper surface of the platform base 101. Acoustic release devices 104 are fixed on both sides of the main float 102. The acoustic release device 104 can also be installed individually, such that one end of the parallel chain 1043 is connected to the release block 1041 at the end of the acoustic release device 104, and the other end is directly connected to the hanging point on the lower surface of the main float 102. An underwater battery compartment 105 is installed inside the main float 102 on one side of the acoustic release device 104. A lifting ring is fixed at the corner of the upper surface of the main float 102. A water outlet alarm is installed on the side of the upper surface of the main float 102. Observation instruments 106 are installed at both ends of the upper surface of the main float 102. The observation instruments 106 can be replaced with different instruments for monitoring according to the monitoring task, and are not limited to monitoring with one instrument. A buoyancy-increasing mechanism is installed on the upper surface of the main float 102. A recovery pulling mechanism is installed at the middle position between the platform base 101 and the upper surface of the main float 102. The buoyancy enhancement mechanism includes a buoyancy enhancement component installed on the upper surface of the main float 102. An inflation component is installed at the top of the buoyancy enhancement component, and a sealing and fixing component is installed at the bottom of the buoyancy enhancement component and the surface of the main float 102. When the device monitors the main float 102 and it is being recovered, the buoyancy enhancement mechanism can stably move the main float 102 upward and reduce water resistance for smooth recovery and reuse.

[0015] In order to facilitate the effective ascent of the main float 102 during recovery by increasing the buoyancy component, in this embodiment, preferably, the buoyancy-increasing component includes a trapezoidal airbag seat 1022 disposed on the upper surface of the main float 102. The bottom end of the trapezoidal airbag seat 1022 is fixed with a base frame 1025 by industrial waterproof adhesive. After the trapezoidal airbag seat 1022 is installed through the base frame 1025, the buoyancy is increased by the trapezoidal airbag seat 1022, while the resistance generated by contact with water is reduced from the top, so the recovery is smooth. In addition, the observation instruments 106 used for monitoring are all sensors and are embedded in the water inside the main float 102, so they are in contact with the water. The trapezoidal airbag seat 1022 is at the top and will not affect the monitoring results.

[0016] In order to facilitate the inflation of the trapezoidal airbag seat 1022 to increase buoyancy through the inflation assembly, in this embodiment, preferably, the inflation assembly includes an inflation port 1024 disposed at the top of the trapezoidal airbag seat 1022. The outer surface of the inflation port 1024 is threaded with a sealing cap 1023, which can be used to inflate the interior of the trapezoidal airbag seat 1022 through the inflation port 1024, and the sealing cap 1023 is rotated to seal and fix it.

[0017] To facilitate the sealing and securing of the bottom end of the bottom frame 1025 to the inner surface of the fixed frame 1021 using a sealing and fixing assembly, in this embodiment, preferably, the sealing and fixing assembly includes a fixed frame 1021 integrally disposed at the edge of the upper surface of the main float 102. The inner surface of the fixed frame 1021 is closed with a sealing gasket 1026. The outer surface of the bottom frame 1025 and the interior of the fixed frame 1021 are sealed and installed by the sealing gasket 1026. The sealing gasket 1026 can be used to tightly press and seal the bottom frame 1025 and the fixed frame 1021, facilitating the fixed installation. The edge of the fixed frame 1021 is threaded with a screw 1027. The surface of the bottom frame 1025 is provided with an internal thread hole that matches the screw 1027. The screw 1027 is rotated again to insert into the internal thread hole for reinforcement.

[0018] The retrieval pulling mechanism includes release components located at the bottom of two acoustic release devices 104. A retrieval pulling component is located at the middle position between the platform base 101 and the main float 102. After monitoring, the retrieval pulling mechanism can detach the platform base 101 from the main float 102 and retrieve it again, which is convenient for operation.

[0019] To facilitate detachment of the bottom of the acoustic release device 104 from the platform base 101 during retrieval via a release assembly, in this embodiment, preferably, the release assembly includes a release block 1041 disposed at the bottom of the acoustic release device 104, a parallel ring 1042 disposed at the middle position inside the platform base 101, and a parallel chain 1043 fixed at the connection point of the two release blocks 1041, with the parallel chain 1043 penetrating the interior of the parallel ring 1042. After monitoring, the acoustic release device 104 can open to detach the release block 1041, thereby detaching the parallel chain 1043, allowing the main float 102 to rise conveniently.

[0020] In order to facilitate the retraction of the platform base 101 by means of the retrieval pulling component, in this embodiment, preferably, the retrieval pulling component includes a rope chamber 103 located at the middle position of the upper surface of the platform base 101 and extending to the middle position inside the main float 102. A rope reel 108 is fixed inside the rope chamber 103. A cable is wound around the outer surface of the rope reel 108 and the end is fixed to the middle position of the lower surface of the main float 102 by bolts. When the main float 102 is raised for retrieval, the top of the cable can be opened and the cable can be wound up again by an external winch to retrieve the platform base 101.

[0021] In this utility model, the instruments used for task monitoring and the acoustic release device 104 are both existing technologies and will not be described in detail here.

[0022] The working principle and usage process of this utility model: When using this seabed-based monitoring device, the main float 102 is first closed to the upper surface of the platform base 101 by the float frame 107. After the platform base 101 and the main float 102 are closed and installed and put into the ocean for monitoring, various sensors are directly mounted according to the needs of the task. The acoustic release device 104's observers, such as physical oceanographic observation sensors, geophysical observation instruments, biochemical oceanographic observation sensors, and other sensors, are used to realize long-term and continuous monitoring of various hydrological parameters of the target sea area, so that the monitoring device can be used to monitor the ocean according to the task. Then, after the seabed-based monitoring device completes its mission and monitoring, it opens the acoustic release device 104, causing the release block 1041 to detach from the bottom of the acoustic release device 104, thereby causing the parallel chain 1043 to detach. After the parallel chain 1043 detaches, the main float 102 is lifted by buoyancy, and as the main float 102 rises, the cable opens from the outer surface of the rope reel 108 inside the rope compartment 103 until the main float 102 is lifted and retrieved. At the top of the main float 102, the cable is slowly retrieved from the winch on the external ship. When the cable is pulled, The platform base 101 is retrievable, making it convenient to retrieve during use. Meanwhile, the main buoy 102 can monitor in either deep or shallow waters. Therefore, the length of the cable reel 108 is determined by whether the monitoring area is in shallow or deep water. This prioritizes the retrieval of instruments and equipment, ensuring data and equipment safety. Furthermore, the platform base 101 can be retrieved from the seabed via cable for reuse, avoiding equipment loss and reducing operating costs. Additionally, by replacing cables of different specifications and lengths, different mission requirements can be met, further reducing procurement costs. Finally, before use, the bottom end of the bottom frame 1025 is embedded into the inside of the fixed frame 1021 and sealed by the sealing gasket 1026. Then, the screw 1027 is rotated to insert into the internal threaded hole on the surface of the bottom frame 1025 to fix the bottom frame 1025 and the trapezoidal airbag seat 1022. After installation, air is injected into the inside of the trapezoidal airbag seat 1022 through the air inlet 1024. The sealing cover 1023 is rotated to seal the air inlet 1024. Therefore, when the main float 102 is recovered after monitoring, the area of ​​the top of the trapezoidal airbag seat 1022 in contact with the water surface is reduced. At the same time, the buoyancy of the main float 102 is increased by the trapezoidal airbag seat 1022, which effectively makes the main float 102 rise and recover without being obstructed. This improves the convenience of the seabed-based monitoring device in rising and recovering the main float 102 after monitoring, increasing buoyancy and reducing resistance.
