Description

Technical Field

[0001] This application relates to the field of instrument observation platform technology, and more specifically, to an automated control device for a bottom-mounted tidal current observation platform. Background Technology

[0002] Seabed tidal current observation is an important method of ocean observation. It uses observation equipment installed on the seabed to monitor tidal currents for a long time and continuously. A seabed tidal current observation platform is usually a device fixed on the seabed to house various observation instruments and equipment. The automated control device of the seabed tidal current observation platform is the core part to realize the platform's automated observation, data acquisition, processing and transmission. This device usually integrates the technologies of various industrial automated control systems to ensure that the observation platform can conduct tidal current observations for a long time, stably and accurately.

[0003] In related technologies, to address the problem of instruments being easily lost or damaged by trawling fishing vessels during operation, for example, patent CN212340245U provides a portable stainless steel bottom-mounted wave and current observation platform. This device uses a hollow steel structure welded from stainless steel plates, making it lightweight and easy to transport. The platform's weight in air is approximately 150 kg, while a reinforced concrete platform weighs over 1.5 tons. Before deployment, fine sand is filled into the opening to increase the platform's weight, ensuring it sits stably on the seabed after being lowered. After observation, divers remove the sand underwater, allowing the platform to be retrieved and reused. It is lightweight and easy to move. Placing the instrument inside the platform avoids damage to the internal instruments caused by trawling operations. In summary, this invention is lightweight, durable, portable, easy to move, convenient to deploy, reusable, and safe and reliable.

[0004] Although the existing technical solutions mentioned above use hollow steel structures welded from stainless steel plates, which are lightweight and can overcome the disadvantages of prefabricated platforms being bulky, having long prefabrication times, and being non-reusable, resulting in certain limitations in their use, the openings restrict the divers' ability to manually excavate the fine sand from the equipment. In complex seabed conditions, such as low visibility, strong currents, and seabed obstacles, the difficulty and time of the divers' sand excavation work will be increased. Not only is the sand excavation efficiency low, but prolonged diving operations may also increase the divers' fatigue, thereby further increasing safety risks.

[0005] In view of this, we propose an automated control device for a bottom-mounted tidal current observation platform. Utility Model Content

[0006] The purpose of this application is to provide an automated control device for a bottom-mounted tidal current observation platform, which can effectively solve the problems in the prior art, such as low sand dredging efficiency and the fact that long-term diving operations may increase the fatigue of divers, thereby further increasing safety risks.

[0007] This application provides an automated control device for a bottom-mounted tidal current observation platform, including a conical body, the top of which has an installation groove, and an observation instrument is installed inside the installation groove;

[0008] The storage bin is located in the middle of the outer side of the conical body. A feed inlet is provided on one side of the outer side of the conical body, and the feed inlet is connected to the inner cavity of the storage bin. A bottom groove is provided at the bottom end of the conical body. An opening and closing component is provided on the surface of the conical body. The opening and closing component includes four opening and closing arc plates. A connecting block is fixedly connected to the top of the outer side of the opening and closing arc plates. The storage bin is provided with an auxiliary unloading component.

[0009] As an optional solution to the technical solution of this application, the connecting block is rotatably connected to the outer side of the conical body through a damping shaft, and the four opening and closing arc plates are distributed in a ring array. The opening and closing of the inner cavity of the storage bin is controlled by the four opening and closing arc plates surrounding the storage bin.

[0010] As an optional solution to the technical solution of this application, the auxiliary feeding component includes a movable bottom ring that is slidably connected to the inner cavity of the storage bin. The top surface of the movable bottom ring is set as an inclined surface. Four fixed plates are fixedly connected to the top of the movable bottom ring. The four fixed plates are arranged in a ring array. A pulley is installed at one end of the fixed plates. The auxiliary feeding component is used in conjunction with the opening and closing component to realize the feeding of the counterweight fine sand in the inner cavity of the storage bin.

[0011] As an optional solution to the technical solution of this application, the conical body is provided with a driving component inside. The driving component includes a movable groove and a built-in groove. The movable groove is opened in the middle of the conical body, and the built-in groove is opened in the bottom of the conical body, so as to allow the auxiliary unloading part to perform lifting and lowering movements, and provide driving force for the opening and closing of the opening and closing part.

[0012] As an optional solution to the technical solution of this application, the inner cavity of the movable groove is slidably connected to a movable disc, and both sides of the inner cavity of the built-in groove are provided with connecting plates. The top of the movable groove is rotatably connected to a threaded rod, the movable disc is threadedly connected to the threaded rod, and the bottom end of the threaded rod slides through the bottom end of the inner wall of the movable groove to the inner cavity of the bottom groove, and is fixedly connected to a turntable.

[0013] As an optional solution to the technical solution of this application, one end of the two connecting plates slides through the inner wall of the built-in groove and is fixedly connected to the bottom end of the movable plate. A top ring is fixedly connected to one side of the two connecting plates, and the top end of the top ring slides through the inner wall of the built-in groove and is fixedly connected to the bottom end of the movable bottom ring.

[0014] As an optional solution to the technical solution of this application, a closing member is provided at the top of the surface of the conical body. The closing member includes a rotating ring that is rotatably connected to the conical body. A through hole is provided on the outer side of the rotating ring. Four abutments are fixedly connected to the bottom edge of the rotating ring to control the opening and closing of the feed inlet.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0016] This application incorporates an opening and closing mechanism, an auxiliary unloading mechanism, and a driving mechanism. When divers retrieve the equipment, rotating the turntable moves the movable disc upward within the movable trough, ultimately causing the movable bottom ring to move upward within the storage bin. Simultaneously, using fixed strips and pulleys, the opening and closing arc plate is pushed upward, opening most of the storage bin's interior. This allows the counterweight material inside to be quickly discharged from the equipment, reducing the diver's time on the seabed, effectively lowering the difficulty, avoiding the tediousness and uncertainty of manual sand dredging, improving operational reliability, and thus increasing sand dredging efficiency.

[0017] This application utilizes a closure mechanism that allows the rotating ring to be rotated after fine sand enters the inner cavity of the storage bin, causing the through-hole and feed inlet to be staggered. This facilitates the opening and closing of the feed inlet by operators, preventing fine sand from leaking out through the through-hole while the equipment is submerged on the seabed. Simultaneously, the staggered positions allow the four abutment blocks and four connecting blocks to overlap, thus preventing the opening and closing mechanism from overturning and discharging sand when not manually operated.

Detailed Implementation

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1-4 This application discloses an automated control device for a bottom-mounted tidal current observation platform, including a conical body 1, with an installation groove 2 at the top of the conical body 1, and an observation instrument 3 installed inside the installation groove 2.

[0025] The storage bin 4 is located in the middle of the outer side of the conical body 1. A feed inlet is provided on one side of the outer side of the conical body 1, and the feed inlet is connected to the inner cavity of the storage bin 4. A bottom groove 5 is provided at the bottom end of the conical body 1. An opening and closing component 6 is provided on the surface of the conical body 1. The opening and closing component 6 includes four opening and closing arc plates 61. A connecting block 62 is fixedly connected to the top of the outer side of the opening and closing arc plates 61. The storage bin 4 is provided with an auxiliary feeding component 7. The connecting block 62 is rotatably connected to the outer side of the conical body 1 through a damping rotating shaft. The four opening and closing arc plates 61 are arranged in a ring array. The opening and closing of the inner cavity of the storage bin 4 is controlled by the four opening and closing arc plates 61 surrounding the storage bin 4.

[0026] The observation instrument 3 is installed at the top of the conical body 1 through the mounting slot 2, ensuring that the observation instrument 3 can work stably and collect accurate data. Sufficient counterweight fine sand is stored in the storage bin 4 to ensure the stability of the observation platform on the seabed. The discharge of counterweight fine sand in the storage bin 4 is controlled by opening and closing the arc plate 61. The design of the connecting block 62 and the damping shaft allows the arc plate 61 to rotate stably and flexibly. The four arc plates 61 form a baffle plate around the storage bin 4 to cover its inner cavity and prevent fine sand from flowing out. When necessary, it can be opened to facilitate material discharge.

[0027] Reference Figure 3 and Figure 4The auxiliary feeding component 7 includes a movable bottom ring 71 that is slidably connected to the inner cavity of the storage bin 4. The top surface of the movable bottom ring 71 is set as an inclined surface. Four fixed strips 72 are fixedly connected to the top of the movable bottom ring 71. The four fixed strips 72 are arranged in a ring array. A pulley 73 is installed at one end of the fixed strips 72. The auxiliary feeding component 6 is used to feed the counterweight fine sand into the inner cavity of the storage bin 4.

[0028] The inclined design of the movable bottom ring 71 facilitates the discharge of fine sand from the gap between the movable bottom ring 71 and the opening and closing arc plate 61 at the moment the opening and closing arc plate 61 is opened. Through the lifting and lowering movement of the movable bottom ring 71, combined with the assistance of the fixed strip 72 and the pulley 73, the counterweight fine sand can be discharged quickly and smoothly.

[0029] Reference Figure 3 and Figure 4 The conical body 1 is equipped with a driving component 8, which includes a movable groove 81 and an internal groove 82. The movable groove 81 is located in the middle of the conical body 1, and the internal groove 82 is located at the bottom of the conical body 1, so as to allow the auxiliary feeding component 7 to move up and down and provide driving force for the opening and closing of the opening and closing component 6. The inner cavity of the movable groove 81 is slidably connected to a movable disc 83. Both sides of the inner cavity of the internal groove 82 are provided with connecting plates 84. The top of the movable groove 81 is rotatably connected to a threaded rod 85. The movable disc 83 is threadedly connected to the threaded rod 85. The bottom end of the threaded rod 85 slides through the bottom end of the inner wall of the movable groove 81 to the inner cavity of the bottom groove 5, and is fixedly connected to a turntable 86. One end of the two connecting plates 84 slides through the inner wall of the internal groove 82 and is fixedly connected to the bottom end of the movable disc 83. One side of the two connecting plates 84 is fixedly connected to a top ring 87. The top end of the top ring 87 slides through the inner wall of the internal groove 82 and is fixedly connected to the bottom end of the movable bottom ring 71.

[0030] The movable groove 81 provides space for the movable disc 83 to move. By rotating the turntable 86, the threaded rod 85 and the movable disc 83 are driven to rise and fall, ultimately realizing the rise and fall of the movable bottom ring 71. The connecting plate 84 and the top ring 87 play a transmission role. Therefore, by the rising and falling movement of the driving component 8, the rising and falling of the auxiliary feeding component 7 is realized, thereby controlling the discharge of the counterweight fine sand.

[0031] Reference Figure 1 and Figure 2 A closing member 9 is provided at the top of the surface of the conical body 1. The closing member 9 includes a rotating ring 91 that is rotatably connected to the conical body 1. A through hole 92 is provided on the outer side of the rotating ring 91. Four abutments 93 are fixedly connected to the bottom edge of the rotating ring 91 to control the opening and closing of the feed port.

[0032] The relative position of the through hole 92 and the feed inlet is controlled by rotating the rotating ring 91, thereby opening and closing the feed inlet. When the rotating ring 91 is rotated to the closed position, the stop block 93 overlaps with the position of the connecting block 62 to prevent the opening and closing arc plate 61 from rotating upwards accidentally.

[0033] In summary, when using the automated control device of the bottom-mounted tidal current observation platform disclosed in this application, the operator first rotates the rotating ring 91 to align the position of the through hole 92 with the position of the feed inlet. At this time, fine sand is poured into the inner cavity of the storage bin 4 from this point. After the inner cavity of the storage bin 4 is filled to a certain extent, the rotating ring 91 can be rotated again to position the four abutment blocks 93 above the four connecting blocks 62 respectively. At this time, the position of the through hole 92 is offset from the position of the feed inlet, completing the closure of the feed inlet. Then, the observation instrument 3 is installed on the mounting slot 2, and the equipment is placed at the designated observation location on the sea surface. Under the weight of the fine sand inside the equipment and its own weight, it sinks into the sea. While observing the seabed location, when staff dived to retrieve the equipment, they first rotated the rotating ring 91 to offset the position of the abutment block 93 from that of the connecting block 62. Then, they flipped the equipment to an inclined position, exposing the bottom groove 5. At this time, they manually rotated the turntable 86, causing the threaded rod 85 to rotate. The movable disc 83 then moved upward within the cavity of the movable groove 81. Through the connecting plate 84 and the top ring 87, they applied an upward force to the movable bottom ring 71. The fixed strip 72 and the pulley 73 first pushed the four opening and closing arc plates 61 upward, causing them to flip and exposing the storage bin 4, allowing the fine sand inside to be quickly discharged from the equipment. Subsequently, the staff retrieved the equipment.
