Description

Technical Field

[0001] This invention relates to the field of underwater topographic observation technology, and in particular to an underwater topographic observation device with attitude sensing and automatic retraction functions. Background Technology

[0002] Topographic observation equipment around the floating piles mainly uses marine buoys or floating platforms, such as observation buoys of specific sizes (e.g., 3-meter monitoring buoys). These devices are fixed to the sea area near the piles by anchoring. Using sensors such as sonar, multibeam echo sounders, and underwater cameras mounted on the floating body, they monitor changes in seabed topography, sediment distribution, and water flow dynamics around the piles in real time. Combined with satellite communication technology, the data is transmitted to the shore-based center to achieve continuous tracking and early warning of seabed stability. This floating solution has both dynamic flexibility and multi-parameter monitoring capabilities, can adapt to complex sea conditions, and provides key support for the safety of marine engineering. Traditional offshore topographic observation equipment often uses buoys floating on the sea surface, with various observation devices fixed below them. When encountering special sea conditions or schools of fish, the observation devices cannot be protected in time and are easily damaged by impacts under special circumstances. When encountering seaweed or schools of fish, traditional observation devices cannot be effectively separated from seaweed or driven away from schools of fish, requiring manual underwater cleaning, which is complicated and time-consuming. Summary of the Invention

[0004] The present invention adopts the following technical solution: An underwater topographic observation device with attitude sensing and automatic retraction functions includes a buoy and a first slide cylinder slidably connected within the buoy. A second slide cylinder is slidably connected to the first slide cylinder, and a placement assembly is installed on the second slide cylinder. A dual-axis motor is fixedly connected to the buoy, and a reciprocating screw is fixedly connected to the output end of each of the dual-axis motors. A threaded sleeve is fixedly connected to the first slide cylinder, and the threaded sleeve and the reciprocating screw are threadedly connected. A first bevel gear is rotatably fitted onto the threaded sleeve. A groove is formed on the reciprocating screw, and the first bevel gear and the reciprocating screw are slidably connected through the groove.

[0006] Preferably, the reciprocating screw is connected through a third slide cylinder, a second rack is fixedly connected to the first slide cylinder, a fourth gear is rotatably connected to the inner wall of the buoy, the fourth gear meshes with the second rack, a fifth gear is fixedly connected to the fourth gear, a third rack and a slide rail are fixedly connected to the inner wall of the third slide cylinder, the third rack and the fifth gear mesh, a connecting plate is slidably connected to the slide rail, a small spring is fixedly connected between the connecting plate and the third slide cylinder, a rotating rod is rotatably connected inside the third slide cylinder, a telescopic sleeve is fixedly connected to the rotating rod, one end of the telescopic sleeve is rotatably connected to the connecting plate, the other end of the telescopic sleeve abuts against the top of the reciprocating screw, and a wind gauge is fixedly connected to the connecting plate.

[0007] Preferably, the circular plate is fixedly connected to a first rack, the inner wall of the buoy is rotatably connected to a third gear, the inner wall of the buoy is slidably connected to a slide plate, and the slide plate meshes with the third gear through a long rack, with the first rack and the third gear being matched.

[0008] Preferably, the buoy has a groove on its upper side, a solar panel is rotatably connected to one side of the groove, a telescopic sleeve is rotatably connected between the solar panel and the groove, and a telescopic connecting plate is fixedly connected to the third sliding cylinder, with the telescopic connecting plate and the solar panel being rotatably connected.

[0009] Preferably, the buoy has a groove on its inner side, and an inclinometer is fixedly connected in the groove. The inclinometer and the dual-axis motor are electrically connected through a controller via sensors.

[0010] Preferably, a rotating cylinder is rotatably connected to the inner wall of the second sliding cylinder, a cam is fixedly connected to the rotating cylinder, a plurality of protrusions are fixedly connected to the reciprocating lead screw, a long groove is opened on the rotating cylinder, the shape of the long groove is opposite to the plurality of protrusions at the lower end of the reciprocating lead screw, and a stop plate is fixedly connected to the upper side of the sliding sleeve.

[0011] The beneficial effects of this invention are: 1. First, when the topographic observation equipment is observing the topography around the marine piles, it can detect when extreme weather causes extreme sea conditions by using an inclinometer to sense that the waves on the sea surface exceed the observation conditions that the equipment can accept, thereby triggering a protection mechanism. Through the setting of multiple sliding cylinders, it not only ensures that the observation equipment can effectively go deep into the sea below the sea level for effective observation, but also can slide and retract into the buoy at the same time, effectively dealing with the damage that extreme sea conditions may cause to the observation equipment. 2. Secondly, during the retraction of the multiple sliding cylinders back to the buoy, while actively protecting the observation equipment from collisions, extreme sea conditions may cause underwater seaweed to float and become entangled, preventing unnecessary impact on the subsequent retraction of the observation equipment and future observations. During the retraction process, when the convex strip and the long groove inside the rotating cylinder slide and connect, the rotating cylinder rotates under the rotation of the reciprocating screw, causing the cam to continuously abut against the abutment plate, thereby causing the lower base to be continuously flung, removing any seaweed that may be entangled on the observation equipment. At the same time, the flung movement can also drive away fish in the surrounding area during the observation process, creating better conditions for effective observation. Meanwhile, the retraction process removes the influence of seaweed, and the operation is simple and requires no manual intervention. 3. Furthermore, in extreme sea conditions, the anemometer on the upper side of the buoy may suffer unnecessary damage from violent collisions caused by extreme waves due to the high precision of the components. When the inclinometer detects that the conditions for overdue testing have been exceeded, the sensor activates the dual-axis motor, which drives the reciprocating screw to rotate. Under the rotation of the reciprocating screw, the fourth sliding cylinder on the upper side of the buoy retracts into the buoy. During the retraction process, the components retract into the fourth sliding cylinder, thereby providing timely and effective protection for the precision components, ensuring normal use during subsequent observations, and saving the cost of replacing damaged components. 4. Immediately following, as the multiple sliding cylinders on the lower side retract, when the first rack and the third gear mesh, the third gear drives the sliding plate to slide, closing the opening on the lower side of the buoy. When the first and second sliding cylinders are completely retracted into the buoy, the sliding plate also completely seals the opening on the lower side of the buoy. In extreme sea conditions, this further promotes the protection of the observation equipment, preventing marine debris from entering after retraction and causing unnecessary collision damage to the detection equipment. Closing the opening on the lower side of the buoy completely prevents debris from entering, which is beneficial for data preservation and equipment protection. 5. Finally, during the process of the third sliding tube retracting into the buoy, the solar panel can also be driven by the telescopic connecting plate. The telescopic sleeve retracts, and the solar panel is laid flat. In extreme sea conditions, the solar panel is also protected to prevent unnecessary collision damage to the supported solar panel. Laying it flat can effectively reduce the possibility of damage to the solar panel caused by extreme sea conditions. While protecting the solar panel, it also ensures a continuous energy supply during the overall testing of the equipment. Attached Figure Description

Detailed Implementation

[0014] See Figures 1-8An underwater topographic observation device with attitude sensing and automatic retraction functions includes a buoy 1 and a first slide cylinder 2 slidably connected inside the buoy 1. A second slide cylinder 3 is slidably connected to the inner side of the first slide cylinder 2. A mounting assembly for fixing the observation equipment is installed on the lower side of the first slide cylinder 3. The observation equipment includes sonar, multibeam echo sounder, and underwater camera. Sonar is primarily used in topographic observation to detect seabed features and sediment distribution through sound waves. The multibeam echo sounder, through wide-sector sound wave transmission and multi-channel reception technology, simultaneously acquires data from hundreds of depth points to achieve three-dimensional seabed topographic modeling. The underwater camera provides real-time visual monitoring, directly observing the seabed environment around the piles, the location of the caisson, and sediment dynamics. Sonar, multibeam echo sounder, and underwater camera are all existing technologies and will not be elaborated upon further. The buoy 1 has a groove on its inner side, and an inclinometer 7 is fixedly connected in the groove. The inclinometer 7 measures the angle by detecting the movement of an air bubble in the sealed cavity due to tilting. Since the dielectric constants of the air bubble and the surrounding liquid are different, the change in its position will change the capacitance value between the internal electrodes. Finally, the tilt angle is accurately calculated by measuring the change in capacitance. The inclinometer 7 is existing technology and will not be described in detail. Inclinometer 7 is used to monitor the tilt angle of buoy 1 in real time. When the tilt angle exceeds a certain preset value, the probability of the observation equipment being damaged by an impact will be greatly increased. At this time, inclinometer 7 will send a signal to the controller through the sensor, and the controller will start the dual-axis motor 5. Inclinometer 7 and dual-axis motor 5 are electrically connected through the controller via the sensor. A dual-axis motor 5 is fixedly connected to the inner wall of buoy 1. A reciprocating screw 6 is fixedly connected to the output end of the dual-axis motor 5. A threaded sleeve 8 is fixedly connected to the inner wall of the first slide cylinder 2. The threaded sleeve 8 and the reciprocating screw 6 are threaded together. A first bevel gear 9 is rotatably connected to the lower side of the threaded sleeve 8. A sliding groove is opened on the reciprocating screw 6. The first bevel gear 9 and the reciprocating screw 6 are slidably connected through the sliding groove. A second bevel gear 10 and a second pulley 13 are rotatably connected to the inner wall of the first slide cylinder 2. The first bevel gear 9 and the second bevel gear 10 mesh with each other. A first pulley 11 is fixedly connected to one side of the second bevel gear 10. The first pulley 11 and the second pulley 13 are connected by a belt 12. A fixing block 14 is fixedly connected to one side of the second slide cylinder 3. The fixing block 14 and the belt 12 are fixedly connected. When the dual-axis motor 5 is started, the output end of the dual-axis motor 5 drives the reciprocating screw 6 to rotate. The reciprocating screw 6 drives the threaded sleeve 8 to move upward along the reciprocating screw 6. At the same time, the reciprocating screw 6 drives the first bevel gear 9 to rotate. The first bevel gear 9 rotates and slides upward along the reciprocating screw 6. The first bevel gear 9 drives the second bevel gear 10 to rotate. The second bevel gear 10 drives the first pulley 11 to rotate. The first pulley 11 drives the second pulley 13 to rotate through the belt 12. The rotation of the belt 12 drives the fixed block 14 to move. The movement of the fixed block 14 drives the second slide cylinder 3 to slide upward along the inner wall of the first slide cylinder 2. The start of the dual-axis motor 5 causes the first slide cylinder 2 and the second slide cylinder 3 to retract back into the buoy 1. The simultaneous retraction of the two slide cylinders greatly improves the retraction efficiency and ensures that the observation equipment is retrieved in time, providing timely protection for the observation equipment. The multi-stage slide cylinder setting also ensures that the observation equipment can be observed at a deeper sea level when observing the terrain. At a deeper sea level, the seawater is more stable, which is conducive to the stable operation of the observation equipment. The placement assembly includes a circular plate 20 fixedly connected to the lower side of the second slide cylinder 3. A threaded rod 15 rotatably passes through the circular plate 20, and the threaded rod 15 is threadedly connected to both the first slide cylinder 2 and the second slide cylinder 3. A sliding rod 16 is fixedly connected to the upper side of the circular plate 20, and the sliding rod 16 slides through the first slide cylinder 2. A first gear 19 is fixedly connected to one side of the threaded rod 15. An arc-shaped slide rail 24 is formed on the circular plate 20, with the threaded rod 15 as its center. A sliding sleeve is slidably connected inside the arc-shaped slide rail 24, and the sliding sleeve and the arc-shaped slide rail 24 are fixedly connected by an arc-shaped spring 25. A connecting rod is rotatably connected inside the sliding sleeve, and a second gear 21 is fixedly connected to the lower side of the connecting rod. A base 22 is fixedly connected to the lower side of the connecting rod, and multiple observation devices are fixedly connected to the lower side of the base 22. A rotating cylinder 17 is rotatably connected to the inner wall of the second sliding cylinder 3. A cam 18 is fixedly connected to the lower side of the rotating cylinder 17. Multiple protrusions 33 are fixedly connected to the lower end of the reciprocating lead screw 6. A long groove is opened on the rotating cylinder 17, which matches the multiple protrusions 33 at the lower end of the reciprocating lead screw 6. A stop plate 23 is fixedly connected to the upper side of the sliding sleeve. The second sliding cylinder 3 slides upward, causing the threaded rod 15 to rotate. The threaded rod 15 drives the first gear 19 to rotate, which in turn drives the second gear 21 to rotate. The second gear 21 then drives the base 22 and the observation equipment fixed to the lower side of the base 22 to rotate. When the second sliding cylinder 3 moves upward and slides into the long groove inside the rotating cylinder 17 and the protrusion 33 at the bottom of the reciprocating screw 6, the rotation of the reciprocating screw 6 drives the rotating cylinder 17 to rotate. The rotating cylinder 17 drives the cam 18 to rotate, and the cam 18 continuously abuts against the abutment plate 23. The abutment plate 23 drives the connecting rod to move along the arc-shaped slide rail 24, and the connecting rod drives the second gear 21 to rotate. The wheel 21 moves along the arc-shaped slide rail 24. Since the arc-shaped slide rail 24 is set with the center of the threaded rod 15, the second gear 21 always maintains meshing with the first gear 19 during the movement. The second gear 21 drives the base 22 and the observation equipment on the base 22 to move, thereby achieving the effect of swinging the observation equipment. The rotation and swinging of the observation equipment can remove the water plants that may be entangled on the observation equipment. At the same time, the swinging can also drive away the fish around during the observation process, creating better conditions for effective observation. Meanwhile, the contraction process removes the influence of water plants. The operation is simple and does not require manual operation. A third slide cylinder 4 is connected through the upper side of the reciprocating screw 6. This "through" means that the third slide cylinder 4 does not contact the reciprocating screw 6. A second rack 29 is fixedly connected to the first slide cylinder 2. A fourth gear 30 is rotatably connected to the inner wall of the buoy 1. The fourth gear 30 meshes with the second rack 29. A fifth gear 31 is fixedly connected to one side of the fourth gear 30. A third rack 32 and a slide rail 37 are fixedly connected to the inner wall of the third slide cylinder 4. The third rack 32 and the fifth gear 31 mesh. A connecting plate 36 is slidably connected to the slide rail 37. A small spring 38 is fixedly connected between the connecting plate 36 and the third slide cylinder 4. An internal rotating rod 35 is connected, and a telescopic sleeve 34 is fixedly connected to the rotating rod 35. The large middle sleeve of the telescopic sleeve 34 is fixedly connected to the rotating rod 35, and the small sleeves on both sides are slidably connected to the large sleeve, with the large middle sleeve providing outward force. One end of the telescopic sleeve 34 is rotatably connected to the connecting plate 36, and the other end of the telescopic sleeve 34 abuts against the top of the reciprocating screw 6. A wind gauge is fixedly connected to the upper side of the connecting plate 36. The wind gauge measures wind speed and wind direction via a rotatable arrow and a fan, thereby assisting the inclinometer in determining whether the sea conditions are suitable for continued observation. This is existing technology and will not be elaborated further. A groove is opened on the upper side of buoy 1, and a solar panel 40 is rotatably connected to one side of the groove. A telescopic sleeve rod 41 is fixedly connected between the solar panel 40 and the groove. A telescopic connecting plate 39 is rotatably connected to the third sliding cylinder 4, and one side of the telescopic connecting plate 39 is rotatably connected to the solar panel 40. The reciprocating screw 6 rotates, causing the first slide cylinder 2 to move upward. The first slide cylinder 2 then drives the second rack 29 to move upward. The second rack 29 drives the fourth gear 30 to rotate, which in turn drives the fifth gear 31 to rotate. The fifth gear 31 then drives the third rack 32 to move downward. The third rack 32 drives the third slide cylinder 4 to move downward. As the third slide cylinder 4 moves downward, the reciprocating screw 6 abuts against the telescopic sleeve 34, which rotates along the rotating rod 35. The telescopic sleeve 34 then drives the connecting plate 36 to slide downward along the slide rail 37. The connecting plate 36 then retracts the anemometer into the third slide cylinder 4, thus providing timely and effective protection for these precision components of the anemometer, ensuring normal operation during subsequent observations, and saving the cost of replacing damaged components. The third sliding cylinder 4 moves downward, causing the connecting plate 39 to rotate. The connecting plate 39 causes the solar panel 40 to rotate along one side of the plate groove, while simultaneously causing the telescopic sleeve 41 to retract, flattening the solar panel 40. In extreme sea conditions, the solar panel 40 is also protected, preventing unnecessary collision damage to the supported solar panel 40. Flattening can effectively reduce the possibility of damage to the solar panel 40 caused by extreme sea conditions, protecting the solar panel 40 while ensuring continuous energy replenishment during the overall testing process of the equipment. A first rack 26 is fixedly connected to the upper side of the circular plate 20. A third gear 27 is rotatably connected to the inner wall of the buoy 1. A sliding plate 28 is slidably connected to the inner wall of the buoy 1. The sliding plate 28 meshes with the third gear 27 through a long rack. The first rack 26 and the third gear 27 are matched and can mesh when in contact. When the second sliding cylinder 3 moves upward, it drives the first rack 26 to move upward. When the first rack 26 moves to mesh with the third gear 27, the first rack 26 drives the third gear 27 to rotate. The third gear 27 drives the sliding plate 28 to slide. When the second sliding cylinder 3 is completely retracted into the buoy 1, the sliding plate 28 completely closes the opening under the buoy 1. The radius of the third gear 27 is greater than the length of the sliding plate 28 and the first rack 26. Therefore, during the movement, the first rack 26 will not hinder the movement of the sliding plate 28. In the event of extreme sea conditions, this further promotes the protection of the observation equipment, preventing sea debris from entering after retraction and causing unnecessary collision damage to the detection equipment. Closing the opening under the buoy completely prevents debris from entering, which is beneficial for data preservation and equipment protection.

[0015] In this invention, when encountering special sea conditions, if the tilt angle exceeds a certain preset value, the probability of the observation equipment being damaged by an impact will be significantly increased. At this time, the inclinometer 7 will activate the dual-axis motor 5 via sensor control. Once activated, the output of the dual-axis motor 5 drives the reciprocating screw 6 to rotate. The reciprocating screw 6 drives the threaded sleeve 8 to move upwards along the reciprocating screw 6. Simultaneously, the reciprocating screw 6 drives the first bevel gear 9 to rotate. As the first bevel gear 9 rotates, it slides upwards along the reciprocating screw 6. The first bevel gear 9 drives the second bevel gear 10 to rotate, and the second bevel gear 10 drives the first pulley 11 to rotate. The pulley 11 drives the second pulley 13 to rotate via the belt 12. The rotation of the belt 12 drives the fixed block 14 to move. The movement of the fixed block 14 causes the second slide cylinder 3 to slide upward along the inner wall of the first slide cylinder 2. The start of the dual-axis motor 5 causes the first slide cylinder 2 and the second slide cylinder 3 to retract back into the buoy 1. The simultaneous retraction of the two slide cylinders greatly improves the retraction efficiency and ensures that the observation equipment is retrieved in a timely manner, providing timely protection for the observation equipment. The multi-stage slide cylinder design also ensures that the observation equipment can be used for observation at a deeper sea level when observing the terrain. The deeper sea level is also more stable, which is conducive to the stable operation of the observation equipment. The second sliding cylinder 3 slides upward, causing the threaded rod 15 to rotate. The threaded rod 15 drives the first gear 19 to rotate, which in turn drives the second gear 21 to rotate. The second gear 21 drives the base 22 and the observation equipment fixed to the lower side of the base 22 to rotate. When the second sliding cylinder 3 moves upward, and the long groove inside the rotating cylinder 17 slides into contact with the protrusion 33 at the bottom of the reciprocating screw 6, the rotation of the reciprocating screw 6 drives the rotating cylinder 17 to rotate. The rotating cylinder 17 drives the cam 18 to rotate, and the cam 18 rotates, continuously abutting the abutment plate 23. The abutment plate 23 drives the connecting rod to move along the arc-shaped slide rail 24, and the connecting rod drives the second... Gear 21 moves along the arc-shaped slide rail 24. Since the arc-shaped slide rail is set around the center of the threaded rod 15, the second gear 21 always remains engaged with the first gear 19 during its movement. The second gear 21 drives the base 22 and the observation equipment on the base 22 to move, thereby achieving the effect of swinging the observation equipment. The rotation and swinging of the observation equipment removes any aquatic plants that may be entangled on it. At the same time, the swinging also drives away fish in the surrounding area during the observation process, creating better conditions for effective observation. The retraction process also removes the influence of aquatic plants. The operation is simple and requires no manual intervention. The reciprocating screw 6 rotates, causing the first slide cylinder 2 to move upward. The first slide cylinder 2 then drives the second rack 29 to move upward. The second rack 29 drives the fourth gear 30 to rotate, which in turn drives the fifth gear 31 to rotate. The fifth gear 31 then drives the third rack 32 to move downward. The third rack 32 drives the third slide cylinder 4 to move downward. As the third slide cylinder 4 moves downward, the reciprocating screw 6 abuts against the telescopic sleeve 34, which rotates along the rotating rod 35. The telescopic sleeve 34 then drives the connecting plate 36 to slide downward along the slide rail 37. The connecting plate 36 then retracts the anemometer into the third slide cylinder 4, thus providing timely monitoring of these precision components. Effective protection ensures normal operation during subsequent observations and saves the cost of replacing damaged components. The downward movement of the third sliding cylinder 4 drives the connecting plate 39 to rotate, which in turn drives the solar panel 40 to rotate along one side of the groove. Simultaneously, it causes the telescopic sleeve 41 to retract, flattening the solar panel 40. This also protects the solar panel 40 in extreme sea conditions, preventing unnecessary collisions that could damage the supported solar panel 40. Flattening the panel effectively reduces the possibility of damage from extreme sea conditions, protecting the solar panel 40 while ensuring a continuous energy supply throughout the overall equipment testing process. When the second slide cylinder 3 moves upward, it drives the first rack 26 to move upward. When the first rack 26 moves to mesh with the third gear 27, the first rack 26 drives the third gear 27 to rotate, and the third gear 27 drives the slide plate 28 to slide. When the second slide cylinder 3 is completely retracted into the buoy 1, the slide plate 28 completely closes the opening under the buoy 1. In the event of extreme sea conditions, this further promotes the protection of the observation equipment, preventing debris from entering the sea after retraction and causing unnecessary collision damage to the detection equipment. Closing the opening on the lower side of the buoy completely prevents debris from entering, which is beneficial for data preservation and equipment protection.
