Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ocean engineering equipment, and in particular to a deep-sea position sensor. BACKGROUND

[0002] The deep-sea position sensor is a core device for deep-sea exploration and operation, used to achieve accurate positioning in high-pressure, darkness, and complex hydrodynamic environments. This type of sensor obtains three-dimensional coordinate information of underwater objects through various technical means, and is a key tool for deep-sea exploration, ocean resource development, seabed engineering, and scientific research.

[0003] The deep-sea position sensor mainly works based on the following technical principles: the acoustic positioning system utilizes the propagation characteristics of sound waves in water, measures the time difference and phase difference of sound waves through an ultra-short baseline (USBL) or long baseline (LBL) transducer array, calculates the relative position of the target, and the effective distance can reach kilometers, but is affected by the change of sound velocity caused by water temperature and salinity stratification, For example, the ocean surveying and mapping positioning device with the application number CN202510162762.X relates to the technical field of ocean surveying and mapping, and the prior art comprises a bearing plate, a waterproof cover is installed at the top end of the bearing plate, a plurality of spiral vanes are fixedly connected at equal angles on the first cavity inner top wall rear side wall through a rotating rod, a second cavity is formed in the inner wall of the weight block, a positioning assembly is installed inside the second cavity, a crushing assembly is installed on the side wall of the rotating rod, and a repairing assembly is installed on the side wall of the spiral vane. By setting the positioning assembly, the rotating rod and the spiral vane are driven to rotate by the motor, the thrust generated by the rotation of the spiral vane is used to drive the device to move towards the seabed, and the device is moved downward by the spiral vane.

[0004] However, the above-mentioned prior art still has some defects when positioning in deep sea: The above-mentioned prior art drives the spiral vane to rotate by a motor to generate thrust, but in actual application, the thrust of the spiral vane will be affected by the water flow in the ocean and will deviate, and the water flow around the propeller will form a vortex when the propeller is working, which will reduce the propulsion efficiency, and the water flow around the propeller blade will form a pressure difference, thereby affecting the stability of the thrust.

[0005] In addition, when positioning and detecting the deep-sea position, the thrust of the spiral vane cannot guarantee that it stays at the predetermined depth, because the size of the thrust depends on the rotation speed of the propeller, the shape and number of the blades, and the density and speed of the fluid, etc. These factors will change constantly in the deep-sea environment, making it difficult to accurately control the thrust generated by the propeller. During the rotation of the spiral vane, a slight difference in the mass distribution of the blade will cause periodic oscillation during rotation, and this oscillation will cause irregular displacement of the device in the depth direction.

[0006] At the same time, the change of the speed of the fluid discharged by the propeller will cause large-scale flow of the surrounding fluid, the gas upstream of the propeller has a suction effect, and the gas downstream has a blowing effect, and the pressure difference resistance and the slow speed of the exhaust wake will also cause the device to be unstable in the depth direction.

[0007] Based on this, in the light of the above-mentioned points, the existing technology for deep-sea positioning still has room for improvement. SUMMARY

[0008] In order to solve the above technical problems, the present application provides a deep-sea position sensor, which adopts the following technical scheme: A deep-sea position sensor, comprising a stand column, the stand column is configured as a hollow structure, and a traction machine is arranged on the stand column; The traction machine comprises a rotating table rotatably arranged at the upper end of the stand column, a boom is arranged on one side of the rotating table, traction wheels are rotatably arranged at both ends of the boom, a winding wheel is rotatably arranged in the hollow structure of the stand column, a traction cable is rotatably arranged on the winding wheel, and a deep-sea submersible is arranged at one end of the traction cable.

[0012] Preferably, a sliding groove is symmetrically formed in both sides of the guide groove, a sliding block is slidably arranged in the sliding groove, and a guide wheel is rotatably arranged between the two sliding blocks.

[0013] Preferably, a return spring is arranged between one end of the sliding block and the sliding groove.

[0014] Preferably, a float is slidably arranged on the traction cable, and one end of the guide rope is connected with the float through the guide wheel.

[0015] Preferably, a reciprocating screw corresponding to the guide groove is rotatably arranged between the top disc and the bottom disc, a bracket threadedly connected with the reciprocating screw is slidably arranged in the receiving hole, and a winding wheel is rotatably arranged on the bracket.

[0017] Preferably, the receiving groove is provided with an elastic net rope wrapping the air bag.

[0018] In summary, the present application comprises at least one of the following beneficial technical effects: 1. The present application uses a pressure sensor to monitor the diving depth in real time, calculates the actual diving speed in combination with the data of sonar technology, and automatically adjusts the thrust distribution of the deep submergence vehicle according to the water flow direction.

DETAILED DESCRIPTION

[0035] The present application is further described below in conjunction with the accompanying drawings. Figures 1 to 12 The present application is further described below in conjunction with the accompanying drawings.

[0036] The present application discloses a deep-sea position sensor, which realizes accurate depth adjustment of a deep-sea submersible by controlling a traction cable to be wound on and off by a winding wheel through a traction device; a buoy realizes buoyancy adjustment by air charging and discharging of an air bag; a protective cover, a spiral blade and a main blade are arranged at the bottom of a shell, and omnidirectional maneuvering and accurate positioning of a deep-sea position are realized through vector thrust cooperative control.

[0037] Embodiment One Reference Figure 1 and Figure 2 ​​As shown in the drawings, a deep sea position sensor comprises a column 1, the column 1 is configured as a hollow structure, a traction machine 2 is arranged on the column 1, the traction machine 2 is installed on a working ship and moves with the ship, when the deep sea position is positioned, the traction machine 2 realizes accurate depth adjustment of the underwater sensor by controlling the steel cable winding and unwinding, the sensor can be sent to different depth layers of the target sea area, the three-dimensional coordinates of the underwater sensor can be calculated by measuring the length and angle of the steel cable unwinding, combined with the ship-borne positioning data, and the deep sea position monitoring is realized.

[0038] Referring to Figure 1 , Figure 2 and Figure 3 , specifically, the traction machine 2 comprises a rotating table 21 rotatably arranged at the upper end of the column 1, a boom 22 is arranged on one side of the rotating table 21, traction wheels 23 are rotatably arranged at both ends of the boom 22.

[0039] When the deep sea position is positioned, first, the motor drives the winding wheel 24 rotatably arranged in the hollow structure of the column 1 to rotate, the winding wheel 24 tightens the traction cable 25 wound thereon, and lifts the submersible 3 arranged at one end of the traction cable 25, and then the motor drives the rotating table 21 to rotate to move the lifted submersible 3 out of the ship cabin.

[0040] After reaching the target sea area, the motor drives the winding wheel 24 to rotate to release the traction cable 25 wound thereon, and the submersible 3 arranged at one end of the traction cable 25 is thrown into the sea, the winding wheel 24 continuously releases the traction cable 25, the length of the traction cable 25 gradually increases, and the submersible 3 begins to slowly dive relying on the difference between its weight and the buoyancy of seawater.

[0041] Through the preset diving trajectory, the motor rotating speed of the winding wheel 24 is dynamically adjusted, the release rate of the traction cable 25 is accurately controlled, the submersible 3 can be controlled to dive to the target depth at a controllable speed, and finally hovers in the predetermined sea area to carry out detection operation.

[0042] Referring to Figure 4 , Figure 5 and Figure 6 , specifically, the submersible 3 comprises a shell 31 arranged at one end of the traction cable 25, an annular cavity 32 is arranged in the shell 31, a water inlet pipe 33 connected with the annular cavity 32 is arranged at the bottom of the shell 31, and a piston plate 34 is slidably arranged in the annular cavity 32.

[0043] When the motor drives the winding wheel 24 to rotate to release the traction cable 25, the shell 31 at one end of the traction cable 25 is thrown into the sea, then the motor drives the threaded rod 35 rotatably arranged 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 enters the annular cavity 32 through the water inlet pipe 33.

[0044] When the weight increment reaches the preset threshold, the release shell 31 begins to dive steadily with the release of the traction cable 25, the depth of the dive of the shell 31 is controlled by the length of the release of the traction cable 25, the diving depth is monitored in real time by using the pressure sensor, and the actual diving speed is calculated by combining the data of the existing sonar technology. The deep-sea submersible 3 automatically adjusts the thrust distribution according to the water flow direction, the threaded rod 35 continuously rotates to control the water inflow, and the deep-sea submersible 3 is ensured to dive to the target operating depth at a stable and controllable speed.

[0045] A gas supply pipe (not shown in the figure) connected with the annular cavity 32 is arranged on the traction rope, one end of the gas supply pipe is connected with the annular cavity 32, and the other end is arranged on the stand column 1. When the shell 31 rises after detection is completed, the motor drives the threaded rod 35 to reverse, the threaded rod 35 drives the piston plate 34 to move downward through the threaded connection with the piston plate 34, and 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 gas supply pipe.

[0046] At this time, the buoyancy of the shell 31 increases, and the shell 31 is lifted by the contraction of the traction cable 25, the motor drives the winding wheel 24 to rotate in reverse to retract the traction cable 25, and the shell 31 is slowly lifted to a predetermined recovery point until the traction cable 25 lifts the shell 31 from the sea surface to complete the recovery.

[0047] Among them, a plurality of guide cylinders 36 slidably connected with the piston plate 34 are arranged in the annular cavity 32, both ends of the guide cylinder 36 penetrate the shell 31, seawater will enter the guide cylinder 36 when the shell 31 dives, and then the motor drives the propeller blade 37 rotatingly arranged in the guide cylinder 36 to rotate, thereby accelerating the diving speed of the shell 31.

[0048] Conversely, when the shell 31 rises after detection is completed, the motor drives the propeller blade 37 to reverse, the propeller blade 37 pushes the seawater downward to generate a reaction thrust to assist the lifting, and the lifting rate is accurately controlled in cooperation with the buoyancy in the annular cavity 32.

[0049] Example two: Referring to Figure 7 , Figure 8 , Figure 9 and Figure 10 , on the basis of example one, when the deep-sea position is continuously positioned, the shell 31 is first placed on the sea surface by releasing the traction cable 25, then the position measuring element 4 arranged in the shell 31 is started after the shell 31 dives into the seabed, the position measuring element 4 rises along the traction cable 25 until it reaches the target position, the position measuring element 4 continuously collects the depth, pressure and acoustic positioning data of each point along the way during the rising process, and the data is fused and processed by real-time transmission to the shipborne control unit. When the position measuring element 4 reaches the preset target position, the point coordinates are locked and recorded as the reference point, and the accurate positioning of the deep-sea position is completed.

[0050] Specifically, the position measuring member 4 comprises a centrally configured accommodating hole 41 in the shell 31, and a top disc 42 and a bottom disc 43 are arranged at two ends of the accommodating hole 41 respectively, and a winding shaft 44 is rotatably arranged between the top disc 42 and the bottom disc 43.

[0051] A guide groove 46 is formed in the upper end of the top disc 42.

[0052] Two symmetrical sliding grooves 461 are formed in the guide groove 46, a sliding block 462 is slidably arranged in the sliding groove 461, a guide wheel 47 is rotatably arranged between the two sliding blocks 462, a reset spring 463 is arranged between one end of the sliding block 462 and the sliding groove 461, and the buoy 5 is slidably arranged on the traction cable 25.

[0053] When the deep sea position is continuously positioned, the shell 31 is first placed on the sea surface by releasing the traction cable 25, and then the shell 31 is submerged to the seabed, and the winding shaft 44 is driven to rotate by the motor to release the guide rope 45 wound thereon, one end of the guide rope 45 passes through the guide wheel 47 and is connected with the buoy 5, and as the guide rope 45 is released, the buoy 5 rises along the traction cable 25 under the action of buoyancy until the buoy 5 moves to the target position.

[0054] The buoy 5 is internally integrated with a high-precision acoustic positioning module and a pressure sensor, continuously collects depth, pressure and acoustic positioning data of each point during the rising process, and transmits the data to the shipborne control unit in real time through a waterproof signal line for data fusion processing, and records the preset target position as a reference point when the buoy 5 moves to the target position, thereby completing the accurate positioning of the deep sea position.

[0055] The top disc 42 and the bottom disc 43 are rotatably arranged with a reciprocating screw 48 corresponding to the guide groove 46, a bracket 49 is slidably arranged in the accommodating hole 41 and is threadedly connected with the reciprocating screw 48, and a winding wheel 491 is rotatably arranged on the bracket 49.

[0056] When the guide rope 45 is released, the winding shaft 44 and the reciprocating screw 48 are connected by a belt transmission mode, and when the winding shaft 44 rotates, the reciprocating screw 48 is driven to rotate synchronously by the belt transmission, and the reciprocating screw 48 drives the winding wheel 491 to reciprocate through the threaded connection with the bracket 49.

[0057] Since the guide rope 45 is connected with the buoy 5 after passing through the winding wheel 491 and the guide wheel 47, the reset spring 463 pushes the sliding block 462 to make the guide wheel 47 push the guide rope 45 to be taut, and at the same time, the winding wheel 491 gradually moves with the release of the guide rope 45, ensuring synchronization with the release of the guide rope 45 and ensuring smooth release of the guide rope 45.

[0058] The guide wheel 47 compensates reversely when the winding wheel 491 moves, dynamically maintains the tension of the guide rope 45, and the guide wheel 47 and the winding wheel 491 form a traction force to prevent the rope body from deviating. Through the cooperation of mechanical transmission and elastic pre-tightening, the mechanism realizes the precise synchronous release and tension maintenance of the guide rope 45, and the buoy 5 rises along the traction cable 25.

[0059] Conversely, after positioning is completed, the motor drives the winding shaft 44 to reverse, at which time the guide rope 45 will be wound on the winding shaft 44, moving the guide rope 45, and the guide rope 45 shortens to pull the buoy 5 to move along the traction cable 25 to the shell 31, thereby continuing to recover the buoy 5. In this process, the winding shaft 44 drives the reciprocating screw 48 to reverse through belt transmission, and the reciprocating screw 48 drives the support 49 to continue reciprocating motion and drive the winding wheel 491 through the threaded connection with the support 49, and the winding wheel 491 guides the guide rope 45 to gradually wind on the winding shaft 44.

[0060] The threaded connection of the reciprocating screw 48 and the support 49 converts the reverse motion into the reciprocating motion of the support 49, drives the winding wheel 491 to move along the guide groove 46, and accurately guides the guide rope 45 to gradually and regularly wind on the winding shaft 44, avoiding uneven winding or knotting of the rope body, ensuring that the buoy 5 recovery process and lowering process are also precisely controllable, and being particularly suitable for fine equipment recovery operation in complex sea conditions.

[0061] Referring to Figure 11 Specifically, the buoy 5 includes a marker base 51 slidingly arranged on the traction cable 25, the marker base 51 is provided with a receiving groove 52, the receiving groove 52 is provided with an air bag 53, and the receiving groove 52 is provided with an elastic net rope 54 wrapping the air bag 53.

[0062] When the buoy 5 needs to float up, the air bag 53 is inflated through the air supply pipe, the elastic net rope 54 is expanded by the air bag 53, the buoy 5 is driven to rise along the traction cable 25 by the buoyancy of the air bag 53, and the air supply pipe is connected with the air supply equipment on the ship body.

[0063] Conversely, the air in the air bag 53 is extracted through the air supply pipe, at which time the air bag 53 contracts, the elastic net rope 54 synchronously tightens, the air bag 53 is retracted into the receiving groove 52, the buoyancy rapidly decreases until completely disappears. At this time, the marker base 51 loses buoyancy under the action of its own weight and stably moves downward along the traction cable 25 for recovery.

[0064] Example three: Referring to Figure 12 On the basis of example one and example two, the shell 31 is provided with a protective cover 6 at the bottom, the protective cover 6 is provided with through holes 61 symmetrically distributed horizontally, and the through holes 61 are provided with spiral blades 62.

[0065] When the shell 31 is submerged in water, the two spiral blades 62 rotate simultaneously, which can make the shell 31 move to one side, and vice versa, the two spiral blades 62 are reversed, which can make the shell 31 rotate, so as to change the orientation of the two spiral blades 62, and then the two spiral blades 62 rotate in the same direction to change the position of the shell 31 in the sea.

[0066] The bottom of the protective cover 6 is provided with a groove 63, and the main paddle 64 is rotatably arranged in the groove 63. The rotation of the main paddle 64 increases the speed of submersion and floating. The shell 31 is provided with an opening 65, which is used for seawater flow to ensure the normal work of the main paddle 64.

[0067] The implementation principle of the present application is: (1) When the deep sea position is positioned, the motor drives the winding wheel 24 rotatably arranged in the hollow structure of the stand column 1 to rotate, the winding wheel 24 tightens the traction cable 25 wound thereon, and one end of the traction cable 25 is arranged on the deep submergence vehicle 3, and then the motor drives the rotating platform 21 to rotate to move the deep submergence vehicle 3 out of the cabin.

[0068] (2) After reaching the target sea area, the motor drives the winding wheel 24 to rotate to release the traction cable 25 wound thereon, and one end of the traction cable 25 is arranged on the deep submergence vehicle 3, and the winding wheel 24 continuously releases the traction cable 25, and the length of the traction cable 25 gradually increases, and the deep submergence vehicle 3 starts to slowly submerge by relying on the difference between the self weight and the buoyancy of seawater.

[0069] (3) When the motor drives the winding wheel 24 to rotate to release the traction cable 25, the shell 31 at one end of the traction cable 25 is placed on the sea surface, and then the motor drives the threaded rod 35 rotatably arranged in the annular cavity 32 to rotate, and 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 enters the annular cavity 32 through the water inlet pipe 33.

[0070] When the weight increment reaches the preset threshold value, the shell 31 starts to stably submerge with the release of the traction cable 25, and the length of the traction cable 25 is released to control the depth of the shell 31.

[0071] (4) The guide rope 45 is provided with a gas supply pipe (not shown in the figure) connected thereto, one end of the gas supply pipe is connected with the annular cavity 32, and the other end is arranged on the stand column 1. When the shell 31 rises after detection is completed, the motor drives the threaded rod 35 to reverse, and the threaded rod 35 drives the piston plate 34 to move downward through the threaded connection with the piston plate 34, so as to discharge seawater in the annular cavity 32 from the water inlet pipe 33, and at the same time, air enters the annular cavity 32 through the gas supply pipe.

[0072] (5): When the deep-sea position is continuously positioned, the traction cable 25 is released to place the shell 31 on the sea surface, and then the shell 31 is submerged to the sea bottom, and the winding shaft 44 is driven to rotate by the motor to release the guide rope 45 wound thereon, one end of the guide rope 45 is wound around the guide wheel 47 and connected with the buoy 5, and as the guide rope 45 is released, the buoy 5 is lifted along the traction cable 25 under the action of the buoyancy until the buoy 5 moves to the target position.

[0073] (6): When the buoy 5 needs to be lifted, the gas-filled tube is used to inflate the air bag 53, the air bag 53 increases the elastic net rope 54 to be stretched out, the air bag 53 generates the buoyancy to drive the marker base 51 to ascend along the traction cable 25.

[0074] Conversely, the air in the air bag 53 is extracted through the gas-filled tube, at this time, the air bag 53 is contracted, the elastic net rope 54 is synchronously tightened, the air bag 53 is put into the containing groove 52, the buoyancy is rapidly reduced until completely disappears. At this time, the marker base 51 loses the buoyancy under the action of its own weight and stably moves downward along the traction cable 25 to be recovered.

[0075] (7): When the shell 31 is submerged in the water, the two spiral blades 62 rotate simultaneously, which can make the shell 31 move to one side, and conversely, the two spiral blades 62 are reversed to rotate, which can make the shell 31 rotate, so as to change the orientation of the two spiral blades 62, and then the two spiral blades 62 rotate in the same direction to change the position of the shell 31 in the sea.

[0076] The embodiments of the specific implementation are the preferred embodiments of the present application, and are not limited to the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
