Description

Technical Field

[0001] The invention relates to the field of ocean surveying and mapping, and more specifically to a floating positioning device for ocean surveying and mapping. Background Art

[0002] Marine surveying and mapping is a general term for the measurement and expression of marine spatial geographic information. It is a specialized discipline that studies the collection, processing, representation, management and application of various geometric, physical, cultural and other geographic spatial information of oceans, rivers, lakes and adjacent land areas. It is an important branch of surveying and mapping and the basis of all marine military, marine scientific research and marine development and utilization activities. The existing technology is to use a float, then install a surveying and mapping component at the bottom of the float, then drop the float into the sea, and then drive the surveying and mapping component to survey the ocean.

[0003] However, during the movement of the float, seaweed plants floating on the sea surface may entangle themselves on the surface of the surveying and mapping components, making the float unable to move, thereby reducing the efficiency of ocean surveying and mapping.

[0004] The prior art has also proposed some solutions. For example, a Chinese patent with authorization announcement number CN220187697U discloses a floating positioning device for ocean surveying. The device uses a rotating blade to cut seaweed plants entangled on the surface of the surveying component, thereby improving the efficiency of the surveying component in surveying the ocean. However, in actual use, the positioning device will not only be entangled by seaweed plants, but will also often encounter severe weather such as storms and rough seas, which will cause the positioning device to fluctuate with the waves on the sea surface, easily causing the positioning device to capsize and making it impossible for the positioning device to survey.

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0044] See also Figures 1 to 10A floating positioning device for ocean surveying and mapping includes a floating body 1, a base 2 is fixedly connected to the lower surface of the floating body 1, a level sensor 5 is fixedly connected to the middle of the upper surface of the base 2, a glass cover 4 is fixedly connected to the lower surface of the base 2, a surveying and mapping device 6 is fixedly connected to the inner top of the glass cover 4, an information processor for receiving signals is fixedly connected to the inner top of the floating body 1, and a floating component 3 for improving the stability of the positioning device is connected to the outer surface of the floating body 1.

[0045] like Figure 1 - Figure 4 As shown, the floating component 3 includes four fixed plates 31 fixed on the outer surface of the float body 1 and an air pump 313 fixed on the middle of the upper surface of the base 2, the interior of the fixed plate 31 is connected with a first rotating joint 32, the top of the first rotating joint 32 is connected to a hollow plate 35, one side of the lower surface of the hollow plate 35 is connected with an air bag 36, the other end of the first rotating joint 32 is connected with an air intake pipe 33, the other ends of the four air intake pipes 33 are connected with the output end of the air pump 313, the input end of the air pump 313 is rotatably connected with a second rotating joint 314, a driving component for driving the hollow plate 35 to rotate is fixedly connected at the diagonal top of the float body 1, counterweight components 37 are fixedly connected on both sides of the inner surface of the float body 1, and a power generation component 38 is rotatably connected to the top of the float body 1.

[0046] The driving component includes a transmission shaft 34 fixed on the upper surface of the hollow plate 35 and two first servo motors 312 fixed at the top diagonal positions inside the float body 1. The output end of the first servo motor 312 is fixedly connected to the fourth gear 311. The top of the transmission shaft 34 is fixedly connected to the third gear 39. The outer surfaces of the four third gears 39 are sleeved with a first synchronous belt 310. The fourth gear 311 is meshed with the third gear 39. The transmission shaft 34 and the first rotary joint 32 are located on the same axis. The first rotary joint 32, the air intake pipe 33, the hollow plate 35 and the airbag 36 are interconnected. The outer surface of the glass cover 4 is connected to a cleaning component 7 for cleaning dirt on the surface of the glass cover 4.

[0047] When encountering stormy weather, the sea is turbulent, driving the float body 1 to tilt left and right with the fluctuation of the sea water. At this time, when the horizontal sensor 5 detects that the tilt angle of the device reaches the set value inside the float body 1, the first servo motor 312 will be started to work and drive the fourth gear 311 to rotate. The fourth gear 311 drives the third gear 39 meshing with it to rotate. Through the transmission of the first synchronous belt 310, the four third gears 39 rotate synchronously, and the hollow plate 35 is driven by the transmission shaft 34 to rotate ninety degrees around the transmission shaft 34, so that the four hollow plates 35 are fully unfolded. At the same time, the air pump 313 work synchronously to deliver gas to the four air inlet pipes 33. The air inlet pipes 33 deliver gas to the inside of the hollow plate 35 through the first rotating joint 32 and finally to the inside of the air bag 36 to make it expand and contact with the sea water to generate buoyancy. The four air bags 36 support the float body 1, so that the contact area between the float body 1 and the sea surface is enlarged and the buoyancy is increased. If rollover occurs, one side needs to be rotated 180 degrees into the water as a whole, and the air bag 36 on one side needs enough force to rotate in the water, which increases the force causing the overall rollover of the device, effectively improves the stability of the device, and reduces the probability of the device rolling over on the sea surface.

[0048] like Figure 4 and Figure 5 As shown, the counterweight assembly 37 includes a water pump 371 fixed on both sides of the inner surface of the float body 1 and a water storage cylinder 375 fixed at the four corners of the lower surface of the base 2. The input end of the water pump 371 is connected to the second conduit 373, the other end of the second conduit 373 is fixedly connected to the filter frame 374, and the output end of the water pump 371 is fixedly connected to the first conduit 372.

[0049] The other end of the first conduit 372 is inserted into the interior of the water storage cylinder 375 and is close to the bottom of the water storage cylinder 375. The upper surface of the water storage cylinder 375 is provided with an air valve for air inlet and outlet.

[0050] When encountering heavy rain, the airbag 36 is promptly deployed and inflated to generate buoyancy, which can increase the force required to ensure that the device rolls over. However, the overall weight of the device is light, and the buoyancy of seawater is naturally small. The part exposed above the water is large, and the center of gravity is higher than the sea surface.

[0051] The water pump 371 is turned on to work, seawater is extracted through the second conduit 373 and the filter frame 374, and the seawater is transferred to the inside of the water storage cylinder 375 through the first conduit 372. The seawater inside the water storage cylinder 375 gradually increases, and the weight of the entire device will also increase accordingly, causing the device to gradually sink, and the airbag 36 is partially submerged in the sea, so that the center of gravity of the entire device is located below the sea surface, thereby ensuring that the device is more difficult to capsize.

[0052] like Figure 4 and Figure 6As shown, the power generation assembly 38 includes a hollow tube 386 rotatably connected to the top of the float body 1, a mounting tube 381 fixed on the upper surface of the float body 1, a generator 388 fixed to the front and rear sides of the upper surface of the base 2, and two other diagonal power sources 389 fixed to the top of the float body 1, the input end of the generator 388 is fixedly connected to the second gear 3810, the outer surface of the hollow tube 386 is fixedly connected to the first gear 387 near the bottom, the outer surface of the hollow tube 386 is fixedly connected to the first bevel gear 382 near the top, one side of the mounting tube 381 is rotatably connected to the rotating shaft 384, one side of the rotating shaft 384 is fixedly connected to the power generation fan blade 385, and the other side of the rotating shaft 384 extends to the interior of the mounting tube 381 and is fixedly connected to the second bevel gear 383.

[0053] The first bevel gear 382 and the rotating shaft 384 are meshed with each other, the first gear 387 and the two second gears 3810 are meshed with each other, the generator 388 is electrically connected to the power source 389 through a wire, and the bottom of the hollow tube 386 is connected to the second rotary joint 314.

[0054] Since the air pump 313 is connected to the hollow tube 386 via the second rotary joint 314, the opening of the hollow tube 386 faces upward, and waves and rainwater can easily enter the interior of the hollow tube 386, causing damage to the air pump 313. At the same time, the abundant wind resources on the sea surface cannot be effectively utilized.

[0055] When strong winds occur on the sea, the power generation fan blades 385 are blown to rotate. The power generation fan blades 385 drive the hollow tube 386 to rotate synchronously through the cooperation of the second bevel gear 383 and the first bevel gear 382. The hollow tube 386 synchronously drives the first gear 387 to rotate. The first gear 387 drives the two second gears 3810 meshing with it to rotate, thereby providing power for the generator 388 to generate electricity. The electricity generated by the generator 388 is transmitted to the power supply 389 through a wire for storage, which can provide electrical energy for the electrical components inside the device, ensuring that the device can work overseas for a long time. At the same time, the top of the hollow tube 386 is located inside the mounting tube 381, thereby ensuring that rainwater and seawater cannot enter the interior of the hollow tube 386, ensuring the safety of the air pump 313 during operation.

[0056] like Figure 7As shown, the cleaning assembly 7 includes a support shaft 76 connected to the outer surface of the glass cover 4 in uniform rotation, a second servo motor 71 fixed to one side of the inner surface of the glass cover 4, and a ring 74 slidably connected to the outer surface of the glass cover 4 near the top, one side of a support shaft 76 is fixedly connected to the fifth gear 72, the other side of a support shaft 76 is fixedly connected to the output end of the second servo motor 71, the outer surfaces of the two support shafts 76 are fixedly connected to the second cleaning brushes 77, the lower surface of the ring 74 is fixedly connected to the third annular rack 75, and the outer surface of the ring 74 is fixedly connected to the anti-blocking assembly 73.

[0057] The second cleaning brush 77 is arc-shaped, one side of the second cleaning brush 77 is in close contact with the outer surface of the glass cover 4 , the fifth gear 72 and the third annular rack 75 are meshed with each other, and the front and rear sides of the lower surface of the base 2 are fixedly connected with an expelling assembly 78 .

[0058] When working overseas, some seabed organisms may adhere to the surface of the glass cover 4, which may hinder the accuracy of the seabed mapping by the mapping device 6. The device needs to be salvaged and cleaned regularly, which increases the workload.

[0059] After working for a certain period of time, the second servo motor 71 is turned on to work, and the fifth gear 72 is driven to rotate forward and reversely through the support shaft 76. The support shaft 76 drives the second cleaning brush 77 to rotate forward and reverse around the support shaft 76. The second cleaning brush 77 can effectively remove the microorganisms attached to the surface of the glass cover 4. At the same time, the glass cover 4 can store the surveying and mapping device 6 inside it, avoiding the surveying and mapping device 6 from directly contacting the seawater, and avoiding rust and corrosion on the contact surface of the surveying and mapping device 6 with the seawater, thereby effectively increasing the service life of the surveying and mapping device 6.

[0060] like Figure 8 As shown, the anti-clogging component 73 includes a second annular rack 733 fixed on the outer surface of the ring 74 and a turntable 731 rotatably connected to the outer surface of the second conduit 373, the outer surface of the turntable 731 is fixedly connected to the first annular rack 732, the outer surfaces of the first annular rack 732 and the second annular rack 733 are jointly sleeved with a second synchronous belt 735, the lower surface of the turntable 731 is fixedly connected to the first cleaning brush 734, and the first cleaning brush 734 is in contact with the surface of the filter frame 374.

[0061] There are various types of seabed microorganisms, which will also adhere to the surface of the filter frame 374, causing clogging of the filter holes inside the filter frame 374. If they are not cleaned in time, the flowability of the filter frame 374 will be affected;

[0062] While the second cleaning brush 77 rotates to clean the surface of the glass cover 4, the fifth gear 72 drives the ring 74 to rotate back and forth on the surface of the glass cover 4 through the third annular rack 75, thereby driving the second annular rack 733 to rotate back and forth. The second annular rack 733 drives the first annular rack 732 to rotate back and forth through the transmission of the second synchronous belt 735, and drives the two first cleaning brushes 734 to wipe the surface of the filter frame 374 through the turntable 731 to clean the dirt attached to the surface of the filter frame 374, so that the filter frame 374 is cleaned synchronously while the glass cover 4 is cleaned, effectively reducing the use of driving components and improving work efficiency.

[0063] like Fig. 9 and Fig.10 As shown, the expulsion assembly 78 includes a mounting plate 781 fixed to the lower surface of the base 2, a sixth gear 782 is rotatably connected to one side of the lower surface of the mounting plate 781, a push rod 783 is fixedly connected to the lower surface of the sixth gear 782, a swing rod 787 is rotatably connected to the middle of the lower surface of the mounting plate 781, a coil spring 784 is fixedly connected to the connection between the swing rod 787 and the mounting plate 781, impact blocks 785 are fixedly connected to both sides of the swing rod 787, two metal sheets 786 are fixedly connected to both sides of the lower surface of the mounting plate 781 away from the sixth gear 782, and the sixth gear 782 is meshed with the second annular rack 733.

[0064] In the ocean, when fish gather around the equipment and swim, they will collide with and overturn the equipment, which will accelerate the damage of the equipment. At this time, the second servo motor 71 is turned on to drive the fifth gear 72 to rotate, and the second annular rack 733 is driven to rotate forward and reverse through transmission. The second annular rack 733 drives the sixth gear 782 to rotate forward and reverse, and the sixth gear 782 drives the push rod 783 to rotate forward and reverse. The push rod 783 pushes the swing rod 787 to rotate around the coil spring 784, so that the swing rod 787 rotates a certain angle and twists the coil spring 784. When the push rod 783 passes through the swing rod 787, the swing rod 787 loses its driving force. Under the action of the coil spring 784, it quickly approaches the metal sheet 786 on one side and hits the metal sheet 786, so that the metal sheet 786 makes a sound. At the same time, the second cleaning brush 77 is constantly rotating forward and reverse. The sound of the metal sheet 786 and the swing of the second cleaning brush 77 can effectively drive away the fish, avoid the appearance of a large number of fish around the equipment, and prevent the equipment from overturning.

[0065] Instructions for use: In case of stormy weather, the airbag 36 can be quickly inflated and expanded to improve the overall stability of the float body 1, effectively preventing the float body 1 from tipping over. At the same time, the overall weight of the device can be adjusted through the counterweight assembly 37, and the center of gravity of the device can be adjusted to a height below the sea level to ensure that the device is more stable. At the same time, the power generation assembly 38 can generate wind power to provide electrical energy for the electrical components on the device. At the same time, the installation cylinder 381 can prevent rainwater and seawater from entering the interior of the hollow tube 386, ensuring the safety of the air pump 313.

[0066] Then, the surface of the glass cover 4 can be wiped by the cleaning component 7 to ensure that the surveying and mapping device 6 can more accurately map the seabed when working. At the same time, the glass cover 4 can provide certain protection for the surveying and mapping device 6 to prevent the surveying and mapping device 6 from being soaked and corroded in seawater. The anti-clogging component 73 cleans the filter frame 374 to ensure the fluidity of the filter frame 374. The expulsion component 78 can make a sound to drive away the fish.

[0067] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
