Description
Technical Field
[0001] This application relates to the technical field of marine engineering equipment, and in particular to a deep-sea position sensor. Background Technology
[0002] Deep-sea positioning sensors are core equipment for deep-sea exploration and operations, used to achieve precise positioning in high-pressure, dark, and complex hydrodynamic environments. These sensors acquire three-dimensional coordinate information of underwater objects through various technical means, and are key tools for deep-sea exploration, marine resource development, seabed engineering, and scientific research.
[0003] Deep-sea positioning sensors primarily operate based on the following technical principles: Acoustic positioning systems utilize the propagation characteristics of sound waves in water. They measure the time difference and phase difference of sound waves through ultra-short baseline (USBL) or long baseline (LBL) transducer arrays to calculate the relative position of the target. The effective range can reach kilometers, but it is affected by changes in sound speed caused by water temperature and salinity stratification.
[0004] For example, a marine surveying and positioning device with application number CN202510162762.X relates to the field of marine surveying and mapping technology. This prior art includes a support plate with a waterproof cover installed at the top. One end of a rotating rod is fixedly connected to multiple helical blades at equal angles through the top and rear side walls of a first cavity. A second cavity is opened in the inner wall of the load-bearing block, and a positioning component is installed inside the second cavity. A crushing component is installed on the side wall of the rotating rod, and a repair component is installed on the side wall of the helical blades. By setting the positioning component, the rotating rod and helical blades are rotated by a motor. The thrust generated by the rotation of the helical blades is used to move the device towards the seabed, and the device is pushed down by the helical blades.
[0005] However, the aforementioned existing technologies still have some shortcomings when it comes to deep-sea positioning:
[0006] The aforementioned prior art generates thrust by driving the propeller blades to rotate using an electric motor. However, in actual applications, the thrust of the propeller blades is affected by the water flow in the ocean, resulting in deviations. When the propeller is working, the surrounding water flow forms vortices, which leads to a reduction in propulsion efficiency. At the same time, the water flow around the propeller blades creates a pressure difference, thereby affecting the stability of the thrust.
[0007] Furthermore, when performing positioning and detection in the deep sea, the thrust of the propeller blades cannot guarantee that it will remain at the predetermined depth. This is because the magnitude of the thrust depends on factors such as the propeller's rotational speed, the shape and number of blades, and the density and velocity of the fluid. These factors are constantly changing in the deep-sea environment, making it difficult to precisely control the thrust generated by the propeller. During the rotation of the propeller blades, even minute differences in the mass distribution of the blades can cause periodic oscillations, which can lead to irregular displacement of the device in the depth direction.
[0008] Meanwhile, the velocity change of the fluid discharged from the propeller will cause large-scale flow of the surrounding environment fluid. The gas upstream of the propeller has a suction effect and a blowing effect downstream. This pressure difference resistance and the phenomenon of slower exhaust velocity will also cause the device to be unstable in the depth direction.
[0009] Based on this, and given the above viewpoints, there is still room for improvement in existing technologies for deep-sea positioning. Summary of the Invention
[0010] To address the aforementioned technical problems, this application provides a deep-sea position sensor, employing the following technical solution:
[0011] A deep-sea position sensor includes a column with a hollow internal structure and a traction machine mounted on the column.
[0012] The towing machine includes a turntable rotatably mounted on the upper end of a column, a boom mounted on one side of the turntable, traction wheels rotatably mounted on both ends of the boom, a winding wheel rotatably mounted inside the hollow structure of the column, a traction cable rotatably mounted on the winding wheel, and a deep-sea submersible mounted on one end of the traction cable.
[0013] The deep-sea submersible includes an outer shell at one end of a towing cable, an annular cavity inside the outer shell, and a water inlet pipe connected to the annular cavity passing through the bottom of the outer shell.
[0014] Preferably, the submersible further includes a piston plate that is slidably disposed within an annular cavity, and a threaded rod that is rotatably disposed within the annular cavity and threadedly connected to the piston plate.
[0015] Preferably, a plurality of guide cylinders are slidably connected to the piston plate inside the annular cavity, and both ends of the guide cylinders penetrate the outer shell. A propeller blade is rotatably installed inside the guide cylinder.
[0016] Preferably, a position measuring element is provided inside the housing;
[0017] The position measuring component includes a receiving hole in the center of the housing, with a top plate and a bottom plate respectively provided at both ends of the receiving hole. A winding shaft is rotatably passed between the top plate and the bottom plate, and a guide rope is wound on the winding shaft.
[0018] A guide groove is provided at the top of the top plate.
[0019] Preferably, sliding grooves are symmetrically provided on both sides of the guide groove, and sliding blocks are slidably arranged in the sliding grooves, with guide wheels rotatably arranged between the two sliding blocks.
[0020] Preferably, a return spring is provided between one end of the sliding block and the sliding groove.
[0021] Preferably, a buoy is slidably mounted on the traction cable, and one end of the guide rope passes around the guide wheel and is connected to the buoy.
[0022] Preferably, a reciprocating screw corresponding to the guide groove is rotatably provided between the top plate and the bottom plate, a bracket threadedly connected to the reciprocating screw is slidably provided in the receiving hole, and a winding wheel is rotatably provided on the bracket;
[0023] The guide rope is connected to the buoy after passing around the winding reel and the guide reel.
[0024] Preferably, the buoy includes a buoy base that is slidably mounted on the towing cable;
[0025] The base has a receiving slot, and an airbag is installed in the receiving slot.
[0026] Preferably, the receiving tank is provided with an elastic mesh rope to wrap the airbag.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. This invention utilizes pressure sensors to monitor the diving depth in real time, combines sonar data to calculate the actual diving speed, and the submersible automatically adjusts the thrust distribution according to the water flow direction. The threaded rod continuously rotates to control the water intake, ensuring that the submersible dives to the target operating depth at a stable and controllable speed.
[0029] 2. In this invention, the guide rope connects to the buoy after passing around the winding wheel and the guide wheel. The reset spring pushes the sliding block to make the guide wheel push the guide rope to tighten. At the same time, the winding wheel moves gradually as the guide rope is released, ensuring synchronization with the release of the guide rope and ensuring smooth release of the guide rope.
[0030] When the winding reel moves, the guide wheel compensates in the opposite direction, dynamically maintaining the tension of the guide rope. The V-grooves of the guide wheel and the winding reel form a self-centering structure to prevent rope deviation. This mechanism achieves precise synchronous release and tension maintenance of the guide rope through the combined action of mechanical transmission and elastic pre-tensioning, allowing the buoy to rise along the traction cable.
[0031] 3. When the outer shell of the present invention is submerged in water, the two helical blades rotate simultaneously, which can make the outer shell move to one side. Conversely, the two helical blades rotate in opposite directions, which can make the outer shell rotate, thereby changing the orientation of the two helical blades. Then, the two helical blades rotate in the same direction to change the position of the outer shell in the sea. Attached Figure Description

[0045] The following is in conjunction with the appendix Figures 1 to 12 This application will be described in further detail.
[0046] This application discloses a deep-sea position sensor, which uses a traction device to control the winding reel to extend and retract the traction cable to achieve precise adjustment of the deep-sea submersible's depth; the buoy uses an airbag to inflate and deflate to achieve buoyancy adjustment; the bottom of the outer shell is equipped with a protective cover, a propeller blade, and a main propeller blade, and achieves omnidirectional maneuvering through vector thrust coordinated control to accurately locate the deep-sea position.
[0047] Example 1:
[0048] Reference Figure 1 and Figure 2 As shown, a deep-sea position sensor includes a column 1 with a hollow internal structure. A tractor 2 is mounted on the column 1 and moves with the vessel during operation. When locating a position in the deep sea, the tractor 2 controls the deployment and retraction of a steel cable to precisely adjust the depth of the underwater sensor. The sensor can be sent to different depth layers in the target sea area. By measuring the length and angle of the steel cable deployment and combining it with the shipborne positioning data, the three-dimensional coordinates of the underwater sensor can be calculated, thus realizing deep-sea position monitoring.
[0049] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the traction machine 2 includes a turntable 21 rotatably mounted on the upper end of the column 1, a boom 22 mounted on one side of the turntable, and traction wheels 23 rotatably mounted on both ends of the boom 22.
[0050] When locating the deep-sea position, the motor first drives the winding wheel 24, which is installed in the hollow structure of the column 1, to rotate. The winding wheel 24 will tighten the traction cable 25 wound on it, lifting the deep-sea submersible 3 at one end of the traction cable 25. Then, the motor drives the turntable 21 to rotate and move the lifted deep-sea submersible 3 out of the cabin.
[0051] Upon reaching the target sea area, the motor drives the winding reel 24 to rotate and release the traction cable 25 wound on it, and the deep-sea submersible 3, which is attached to one end of the traction cable 25, is deployed on the sea surface. The winding reel 24 continues to release the traction cable 25, and the length of the traction cable 25 gradually increases. The deep-sea submersible 3 begins to slowly descend by relying on its own weight and the difference in buoyancy of the seawater.
[0052] By dynamically adjusting the speed of the motor of the winding wheel 24 according to the preset diving trajectory, the release rate of the traction cable 25 is precisely controlled to ensure that the deep-sea submersible 3 descends to the target depth at a controllable speed and finally hovers in the predetermined sea area to carry out exploration operations.
[0053] Reference Figure 4 , Figure 5 and Figure 6 As shown, specifically, the deep-sea submersible 3 includes a shell 31 provided at one end of the towing cable 25, an annular cavity 32 provided inside the shell 31, a water inlet pipe 33 connected to the annular cavity 32 passing through the bottom of the shell 31, and a piston plate 34 slidably provided inside the annular cavity 32.
[0054] When the motor drives the winding wheel 24 to rotate and release the traction cable 25, the outer shell 31 at one end of the traction cable 25 is dropped onto the sea surface. Then, the motor drives the threaded rod 35, which is rotatably installed in the annular cavity 32, to rotate. The threaded rod 35 drives the piston plate 34 to move upward through the threaded connection with the piston plate 34. At this time, seawater will enter the annular cavity 32 through the water inlet pipe 33.
[0055] When the weight increment reaches a preset threshold, the outer shell 31 begins to descend steadily as the tow cable 25 is released. The descent depth of the outer shell 31 is controlled by the length of the tow cable 25 release. The descent depth is monitored in real time using pressure sensors, and the actual descent speed is calculated by combining data from existing sonar technology. The submersible 3 automatically adjusts the thrust distribution according to the water flow direction, and the threaded rod 35 continuously rotates to control the water intake, ensuring that the submersible 3 descends to the target operating depth at a stable and controllable speed.
[0056] An air supply pipe (not shown in the figure) is provided on the traction rope and connected to the annular cavity 32. One end of the air supply pipe is connected to the annular cavity 32, and the other end is set on the column 1. When the detection is completed and the outer shell 31 rises, the motor drives the threaded rod 35 to reverse. The threaded rod 35 is driven to move downward through the threaded connection with the piston plate 34, so that the seawater in the annular cavity 32 is discharged from the water inlet pipe 33, and at the same time, air enters the annular cavity 32 through the air supply pipe.
[0057] At this time, the buoyancy of the outer shell 31 increases, and with the contraction of the traction cable 25, the outer shell 31 floats up. The motor drives the winding wheel 24 to rotate in the opposite direction to retract the traction cable 25, and slowly floats up to the predetermined recovery point until the traction cable 25 lifts the outer shell 31 from the sea surface to complete the recovery.
[0058] The annular cavity 32 is equipped with multiple guide tubes 36 that are slidably connected to the piston plate 34. Both ends of the guide tubes 36 penetrate the outer shell 31. When the outer shell 31 submerges, seawater enters the guide tubes 36 and then the propeller blades 37 inside the guide tubes 36 are rotated by the motor, thereby accelerating the submersion speed of the outer shell 31.
[0059] Conversely, when the detection is complete and the outer shell 31 rises, the motor drives the propeller blade 37 to reverse, and the propeller blade 37 pushes the seawater downward, generating a reaction thrust to assist in buoyancy. This, combined with the buoyancy adjustment in the annular cavity 32, precisely controls the rate of ascent.
[0060] Example 2:
[0061] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, based on Embodiment 1, when continuing to locate the deep-sea position, the towing cable 25 is first released to place the outer shell 31 on the sea surface. Then, after the outer shell 31 submerges into the seabed, the position measuring device 4 installed inside the outer shell 31 is activated. The position measuring device 4 rises along the towing cable 25 until it reaches the target position. During the ascent, the position measuring device 4 continuously collects depth, pressure, and acoustic positioning data at various points along the way, and transmits this data in real time to the shipboard control unit for data fusion processing. When the position measuring device 4 reaches the preset target position, the coordinates of that point are locked and recorded as a reference point, completing the precise positioning of the deep-sea position.
[0062] Specifically, the position measuring component 4 includes a receiving hole 41 in the center of the outer shell 31, with a top plate 42 and a bottom plate 43 respectively provided at both ends of the receiving hole 41, and a winding shaft 44 rotatably passing between the top plate 42 and the bottom plate 43.
[0063] A guide groove 46 is provided at the upper end of the top plate 42.
[0064] The guide groove 46 has symmetrical sliding grooves 461 on both sides. Sliding blocks 462 are slidably arranged in the sliding grooves 461. A guide wheel 47 is rotatably arranged between the two sliding blocks 462. A return spring 463 is arranged between one end of the sliding block 462 and the sliding groove 461. A buoy 5 is slidably arranged on the traction cable 25.
[0065] When continuing to locate the deep-sea position, the tow cable 25 is first released to place the outer shell 31 on the sea surface. Then, after the outer shell 31 submerges into the seabed, the motor drives the winding shaft 44 to rotate and release the guide rope 45 wound on it. One end of the guide rope 45 passes around the guide wheel 47 and connects to the buoy 5. As the guide rope 45 is released, the buoy 5 rises along the tow cable 25 under the action of buoyancy until the buoy 5 moves to the target position.
[0066] Buoy 5 integrates a high-precision acoustic positioning module and pressure sensor. During its ascent, it continuously collects depth, pressure, and acoustic positioning data at various points and transmits them in real time to the shipboard control unit via a waterproof signal line for data fusion processing. When buoy 5 moves to the preset target position, it is recorded as the reference point, thus completing the precise positioning of the deep-sea location.
[0067] Among them, a reciprocating screw 48 corresponding to the guide groove 46 is rotatably passed between the top plate 42 and the bottom plate 43, and a bracket 49 threadedly connected to the reciprocating screw 48 is slidably arranged in the receiving hole 41, and a winding wheel 491 is rotatably arranged on the bracket 49.
[0068] When the guide rope 45 is released, the winding shaft 44 and the reciprocating screw 48 are connected by a belt drive. When the winding shaft 44 rotates, it will drive the reciprocating screw 48 to rotate synchronously through the belt drive. The reciprocating screw 48 will drive the winding wheel 491 to reciprocate through the threaded connection with the bracket 49.
[0069] Since the guide rope 45 is connected to the buoy 5 after passing around the winding wheel 491 and the guide wheel 47, the return spring 463 will push the sliding block 462 to make the guide wheel 47 push the guide rope 45 to tighten. At the same time, the winding wheel 491 will gradually move as the guide rope 45 is released, ensuring that it is synchronized with the release of the guide rope 45 and ensuring the smooth release of the guide rope 45.
[0070] When the winding wheel 491 moves, the guide wheel 47 compensates in the opposite direction, dynamically maintaining the tension of the guide rope 45. The guide wheel 47 and the winding wheel 491 form a traction force to prevent the rope from deviating. This mechanism achieves precise synchronous release and tension maintenance of the guide rope 45 through the coordinated action of mechanical transmission and elastic pre-tensioning, and the buoy 5 rises along the traction cable 25.
[0071] Conversely, after positioning is completed, the motor drives the winding shaft 44 to reverse. At this time, the guide rope 45 will wind around the winding shaft 44. Moving the guide rope 45 shortens it, pulling the buoy 5 along the traction cable 25 towards the outer casing 31, thus continuing to retrieve the buoy 5. During this process, the winding shaft 44 will drive the reciprocating screw 48 to reverse through belt drive. The reciprocating screw 48 is driven to continue reciprocating through the threaded connection with the bracket 49 and drives the winding wheel 491. The winding wheel 491 guides the guide rope 45 to gradually wind around the winding shaft 44.
[0072] The threaded connection between the reciprocating screw 48 and the bracket 49 converts the reversing motion into the reciprocating motion of the bracket 49, which drives the winding wheel 491 to move along the guide groove 46, precisely guiding the guide rope 45 to gradually and regularly wind around the winding shaft 44. This avoids uneven winding or knotting of the rope, ensuring that the buoy 5 recovery process is as precise and controllable as the deployment process. It is particularly suitable for fine equipment recovery operations in complex sea conditions.
[0073] Reference Figure 11 As shown, specifically, the buoy 5 includes a buoy base 51 that is slidably mounted on the towing cable 25. The buoy base 51 has a receiving groove 52, an airbag 53 is installed in the receiving groove 52, and an elastic net rope 54 that wraps the airbag 53 is installed in the receiving groove 52.
[0074] When buoy 5 needs to rise, air is supplied to airbag 53 through the air supply pipe. The airbag 53 expands and expands the elastic net rope 54. The airbag 53 generates buoyancy and drives the buoy seat 51 to rise along the traction cable 25. The air supply pipe is connected to the air supply equipment on the hull.
[0075] Conversely, by extracting air from the airbag 53 through the air supply pipe, the airbag 53 contracts, and the elastic net rope 54 tightens simultaneously, drawing the airbag 53 into the receiving slot 52. The buoyancy rapidly decreases until it disappears completely. At this point, the marker 51 loses buoyancy under its own weight and steadily descends along the traction cable 25 for recovery.
[0076] Example 3:
[0077] Reference Figure 12 As shown, based on Embodiment 1 and Embodiment 2, a protective cover 6 is provided at the bottom of the outer shell 31, and symmetrically distributed through holes 61 are provided on the protective cover 6. Spiral blades 62 are provided inside the through holes 61.
[0078] When the outer shell 31 is submerged in water, the two helical blades 62 rotate simultaneously, which can make the outer shell 31 move to one side. Conversely, the two helical blades 62 rotate in reverse, which can make the outer shell 31 rotate, thereby changing the orientation of the two helical blades 62. Then, the two helical blades 62 rotate in the same direction to change the position of the outer shell 31 in the sea.
[0079] The bottom of the protective cover 6 has a groove 63, and the main propeller 64 is rotatably mounted in the groove 63. By driving the main propeller 64 to rotate, the speed of diving and surfacing is increased. The outer shell 31 has an opening 65 to allow seawater flow and ensure the normal operation of the main propeller 64.
[0080] The implementation principle of this invention is as follows:
[0081] (1): When positioning the deep-sea location, the winding wheel 24, which is installed in the hollow structure of the column 1, is first rotated by the motor. The winding wheel 24 will tighten the traction cable 25 wound on it, and lift the deep-sea submersible 3 at one end of the traction cable 25. Then the motor drives the turntable 21 to rotate and move the lifted deep-sea submersible 3 out of the cabin.
[0082] (2): After reaching the target sea area, the motor drives the winding wheel 24 to rotate and release the traction cable 25 wound on it. The deep-sea submersible 3, which is set at one end of the traction cable 25, is launched on the sea surface. The winding wheel 24 continues to release the traction cable 25, and the length of the traction cable 25 gradually increases. The deep-sea submersible 3 begins to slowly descend by relying on its own weight and the difference in buoyancy of the seawater.
[0083] (3): When the motor drives the winding wheel 24 to rotate and release the traction cable 25, the outer shell 31 at one end of the traction cable 25 is placed on the sea surface. Then the motor drives the threaded rod 35, which is rotated in the annular cavity 32, to rotate. The threaded rod 35 drives the piston plate 34 to move upward through the threaded connection with the piston plate 34. At this time, seawater will enter the annular cavity 32 through the water inlet pipe 33.
[0084] When the weight increment reaches a preset threshold, the outer shell 31 begins to descend steadily as the traction cable 25 is released. The depth of descent of the outer shell 31 is controlled by the length of the traction cable 25 released.
[0085] (4): A connecting air supply pipe (not shown in the figure) is provided on the guide rope 45. One end of the air supply pipe is connected to the annular cavity 32, and the other end is set on the column 1. When the outer shell 31 rises after the detection is completed, the motor drives the threaded rod 35 to reverse. The threaded rod 35 is driven to move downward through the threaded connection with the piston plate 34, so that the seawater in the annular cavity 32 is discharged from the water inlet pipe 33, and at the same time, air enters the annular cavity 32 through the air supply pipe.
[0086] (5): When continuing to locate the deep-sea position, first release the tow rope 25 to place the outer shell 31 on the sea surface. Then, after the outer shell 31 is submerged into the seabed, the motor drives the winding shaft 44 to rotate and release the guide rope 45 wound on it. One end of the guide rope 45 passes around the guide wheel 47 and connects to the buoy 5. As the guide rope 45 is released, the buoy 5 rises along the tow rope 25 under the action of buoyancy until the buoy 5 moves to the target position.
[0087] (6): When the buoy 5 needs to rise, it is inflated by the air supply pipe into the airbag 53. The airbag 53 increases in size and expands the elastic net rope 54. The airbag 53 generates buoyancy and drives the buoy seat 51 to rise along the traction cable 25.
[0088] Conversely, by extracting air from the airbag 53 through the air supply pipe, the airbag 53 contracts, and the elastic net rope 54 tightens simultaneously, drawing the airbag 53 into the receiving slot 52. The buoyancy rapidly decreases until it disappears completely. At this point, the marker 51 loses buoyancy under its own weight and steadily descends along the traction cable 25 for recovery.
[0089] (7): When the outer shell 31 is submerged in water, the two spiral blades 62 rotate simultaneously, which can make the outer shell 31 move to one side. Conversely, the two spiral blades 62 rotate in reverse, which can make the outer shell 31 rotate, thereby changing the orientation of the two spiral blades 62. Then the two spiral blades 62 rotate in the same direction to change the position of the outer shell 31 in the sea.
