Description

Technical Field

[0001] This invention relates to the field of marine surveying equipment technology, and in particular to a floating marine surveying device with seawater detection function. Background Technology

[0002] Marine surveying is the collective term for surveying and charting work conducted on ocean waters and the seabed. It is both an important branch of surveying science and a comprehensive discipline involving many related sciences. It represents the application and development of terrestrial surveying methods in the ocean, focusing on surveying and charting work on ocean waters and the seabed. All marine activities, whether economic, military, or scientific research, require marine surveying to provide various types of marine geographic information elements, data, and basic maps. This mainly includes hydrographic surveying, marine geodetic surveying, seabed topographic surveying, marine thematic surveying, and the compilation of nautical charts, seabed topographic maps, various marine thematic maps, and marine atlases.

[0003] In existing technologies, marine surveying typically only maps and detects the surface seawater, and cannot extract seawater at different depths for secondary detection. During the detection process, the marine surveying device floats on the sea surface. Small-sized marine surveying devices need to be fixed to prevent them from deviating. They can only extract and detect seawater in local sea areas, leading to inaccurate detection and affecting the detection results. Therefore, this invention proposes a floating marine surveying device with seawater detection function. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a floating marine mapping device with seawater detection capabilities. This invention can detect seawater at different depths in the ocean and store the seawater during detection for secondary detection, thereby improving detection accuracy. It can also locate the mapping device's position in real time and automatically adjust its position without the need for fixing, thus improving the accuracy of marine mapping. By setting floating devices on four sides and balancing blocks at the bottom, it prevents the mapping device from tipping over, improving stability during seawater detection. The device has a simple structure and is easy to operate.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A floating marine mapping device with seawater detection function includes a marine mapping frame, a transparent sealing cover, and buoyancy expansion bags. The transparent sealing cover, made of a light-transmitting material, is sealed at the top of the marine mapping frame. A solar panel is installed on the top inner wall of the transparent sealing cover, and the solar panel is connected to a battery panel installed inside the transparent sealing cover. The marine mapping frame has a hollow internal structure, and its surface is square. Two pairs of symmetrical buoyancy expansion bags are installed on the sides of the marine mapping frame. Multiple sets of buoyancy expansion bags are of the same size, and each set of buoyancy expansion bags contains an air pressure sensor. The buoyancy expansion bags are connected to a diversion valve via air guide pipes, and the diversion valve is connected to an inflation device installed inside the marine mapping frame. An air inlet check valve is installed between the air duct and the buoyancy expansion bag. An electrically controlled check valve for venting is installed on the buoyancy expansion bag. A position sensor is installed inside the marine surveying frame. An adjustment component for adjusting its position is provided on the marine surveying frame. A connecting rod is installed at the middle of the bottom of the marine surveying frame. A seawater collection component is provided on the connecting rod. A balance block is installed at the other end of the connecting rod. The balance block is made of solid rust-proof metal. A depth sensor and a water quality sensor are installed on the balance block. The air pressure sensor, air inflator, electrically controlled check valve, position sensor, depth sensor, and water quality sensor are all connected to a PLC controller. The PLC controller is connected to the battery panel and is installed inside a transparent sealed cover.

[0007] By adopting the above technical solution, this invention converts solar energy into electrical energy through solar panels and stores it through battery panels. Buoyancy expansion bags are installed on the four sides of the marine mapping rig, and pressure sensors are installed inside the expansion bags to detect the air pressure in real time. Based on the air pressure information, the PLC controller controls the air inflator to allow air intake and the electrically controlled one-way valve to allow air exhaust, thus controlling the marine mapping rig to float on the sea surface or sink into the ocean. Position information is transmitted to the PLC controller via a position sensor to detect the position of the marine mapping rig in real time. The depth sensor measures the sinking depth of the marine mapping rig, the water quality sensor detects parameters of compounds in the seawater, and the seawater is collected by a seawater collection device for secondary analysis.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the adjusting component includes a rotary motor, an angle adjusting shaft, a toggle impeller, and a transmission motor; the rotary motor is installed inside the marine surveying frame; a fixed mounting frame is fixed to the bottom of the marine surveying frame; the rotary motor is connected to an angle adjusting shaft that passes through the fixed mounting frame; an adjusting frame is connected to the other end of the angle adjusting shaft; a toggle impeller that can rotate along the adjusting frame is installed inside the adjusting frame via a transmission shaft; an angle sensor is installed on the adjusting frame; a sealing platform is fixed to one end of the adjusting frame; a transmission motor connected to the transmission shaft is installed inside the sealing platform; and the rotary motor, angle sensor, and transmission motor are all connected to a PLC controller.

[0009] By adopting the above technical solution, the present invention receives angle information from the angle sensor through a PLC controller, converts the angle information into data information and sends it to the PLC controller. The PLC controller controls the rotation of the rotary motor, which drives the angle adjustment shaft to rotate inside the fixed mounting frame. The rotation of the angle adjustment shaft drives the adjustment frame to adjust the angle. After the adjustment is completed, the PLC controls the drive motor to work. The drive motor drives the agitator to rotate through the drive shaft. The rotation of the agitator drives the marine surveying frame to move, thereby adjusting the position of the marine surveying frame.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the seawater collection component includes a collection rack, a sealing plug, and a buoyancy plate. The collection rack is mounted on a connecting rod via a disassembly component. Multiple collection tanks are formed inside the collection rack. Each set of collection tanks is sealed by a sealing plug. An elastic sealing hose is provided between the sealing plug and the collection tank. A tension spring is installed inside the elastic sealing hose. Both ends of the tension spring are connected to the collection rack and the sealing plug, respectively. The tension spring force is different in each set of collection tanks. A buoyancy plate is placed at the bottom of the collection tank. A powerful magnetic block is fixed at the top of the collection tank. An attractive iron plate is installed on the buoyancy plate directly below the powerful magnetic block. A liquid level sensor is installed inside the collection tank and is connected to a PLC controller.

[0011] By adopting the above technical solution, when the marine surveying frame reaches a certain depth, the tension of the spring is less than the pressure of the seawater, and the sealing plug moves into the collection tank. Seawater enters the collection tank, and the liquid level sensor detects the liquid level information and transmits it to the PLC controller. The PLC controller controls the water quality sensor to perform water quality detection. When seawater enters a set of the collection tanks, the buoyancy plate floats upward, driving the attracting iron plate to move upward. When the liquid inside the collection tank gradually fills up, the strong magnetic block attracts the attracting iron plate, pushing the sealing plug upward to seal the set of collection tanks. By using different tensions of the spring, seawater at different depths and pressures can be collected and detected, improving the accuracy of the detection.

[0012] In a preferred embodiment, the present invention may be further configured such that: the disassembly component includes a disassembly bolt and a disassembly cover plate, the mounting end of the disassembly cover plate is configured as a concave arc shape, and the arc surface is provided with anti-slip teeth, the disassembly cover plate is embedded inside the liquid collection rack and fits against the connecting rod, and the disassembly bolt passes through the disassembly cover plate and is connected to the liquid collection rack by threads.

[0013] By adopting the above technical solution, the present invention connects the disassembly cover plate and the liquid collection rack by disassembly bolts, which enables convenient disassembly of the liquid collection rack and facilitates subsequent testing of the seawater inside the liquid collection rack.

[0014] In a preferred embodiment, the present invention can be further configured such that: the outer wall of the buoyancy plate is attached to the inner wall of the liquid collection tank, the middle part of the buoyancy plate has a hollow structure, and the buoyancy of the buoyancy plate is much greater than the pressure of the attracting iron sheet.

[0015] By adopting the above technical solution, the present invention makes it easy to lift the attracting iron sheet by using buoyancy greater than the pressure of the attracting iron sheet, and the hollow structure in the middle reduces the weight and facilitates the entry of seawater into the bottom of the collection tank.

[0016] In a preferred embodiment, the present invention can be further configured such that: an electrically controlled power-off switch is installed inside the transparent sealing cover; the electrically controlled power-off switch is located between the solar panel and the battery panel; the battery panel is connected to a power detector; the power detector is connected to a PLC controller; and the PLC controller is wirelessly connected to a control terminal.

[0017] By adopting the above technical solution, the present invention detects the power of the solar panel through a power detector. When the solar panel is fully charged, the PLC controller controls the power-off switch to cut off the power. When the power is lower than the set value, the PLC controller controls the inflator to blow air into the buoyancy expansion bag to make the marine surveying frame float and store electricity through the solar panel.

[0018] In a preferred embodiment, the present invention can be further configured such that: an embedding groove is provided on the marine mapping frame, the transparent sealing cover is embedded in the embedding groove, and the embedded end of the transparent sealing cover is sealed with the embedding groove by a waterproof adhesive.

[0019] By adopting the above technical solution, the present invention improves the stability of the connection by setting an embedded slot.

[0020] In a preferred embodiment, the present invention can be further configured such that: the connecting rod has a hollow structure inside, the inner wall of the connecting rod is fixed with reinforcing ribs, and the connecting rod is provided with wiring for connecting the depth sensor and the water quality sensor.

[0021] By adopting the above technical solution, the present invention uses a hollow structure for the connecting rod to facilitate circuit connection, while also providing effective waterproofing.

[0022] In summary, the present invention has at least one of the following beneficial technical effects:

[0023] 1. This invention can detect seawater at different depths in the ocean and can store seawater during detection for secondary detection, thereby improving the accuracy of detection. At the same time, it can locate the position information of the surveying device in real time and automatically adjust the position of the surveying device without fixing it, thus improving the accuracy of marine surveying. By setting floating devices on four sides and setting balance blocks at the bottom, it prevents the surveying device from overturning, thereby improving the stability of seawater detection. The structure is simple and the operation is convenient.

[0024] 2. This invention increases the center of gravity of the marine surveying frame by using counterweights, and improves the stability of the marine surveying frame by using buoyancy forces acting on the sides of the frame, effectively preventing the marine surveying frame from tipping over during surveying.

[0035] The adjusting components include a rotary motor 19, an angle adjusting shaft 22, a toggle impeller 24, and a drive motor 26. The rotary motor 19 is installed inside the marine surveying rig 1. A fixed mounting bracket 21 is fixed to the bottom of the marine surveying rig 1. The rotary motor 19 is connected to an angle adjusting shaft 22 that passes through the fixed mounting bracket 21.

[0036] The seawater collection system includes a collection rack 6, a sealing plug 31, and a buoyancy plate 30. The collection rack 6 is mounted on a connecting rod 7 via a disassembly mechanism. Multiple collection tanks are located inside the collection rack 6, each sealed by a sealing plug 31. An elastic sealing hose 32 is installed between the sealing plug 31 and the collection tank. A tension spring 33 is installed inside the elastic sealing hose 32, with its two ends connected to the collection rack 6 and the sealing plug 31 respectively. The tension spring 33 has a different elastic force in each collection tank. A buoyancy plate 30 is placed at the bottom of the collection tank, and a strong magnetic block 28 is fixed at the top of the collection tank. An attractive iron plate 29 is installed on the buoyancy plate 30 directly below the strong magnetic block 28. A liquid level sensor 34 is installed inside the collection tank, and the liquid level sensor 34 is connected to a PL... When the marine surveying frame 1 reaches a certain depth, the tension of the spring 33 is less than the pressure of the seawater, and the sealing plug 31 moves into the collection tank. Seawater enters the collection tank, and the liquid level sensor 34 detects the liquid level information and transmits it to the PLC controller 10. The PLC controller 10 controls the water quality sensor 13 to perform water quality detection. When seawater enters a set of collection tanks, the buoyancy plate 30 floats upward, driving the magnetic iron plate 29 to move upward. When the liquid in the collection tank gradually fills up, the strong magnetic block 28 attracts the magnetic iron plate 29, pushing the sealing plug 31 to move upward and sealing the set of collection tanks. By varying the tension of the spring 33, seawater at different depths and pressures can be collected and detected, improving the accuracy of the detection.

[0037] The collection tank is divided into a first collection tank, a second collection tank, a third collection tank, and a fourth collection tank. The volume of liquid in the first collection tank is 10-60 ml, the volume in the second collection tank is 10-60 ml, the volume in the third collection tank is 10-60 ml, and the volume in the fourth collection tank is 10-60 ml. The tension spring 33 is also divided into a first tension spring, a second tension spring, a third tension spring, and a fourth tension spring. The first tension spring is installed inside the first collection tank, the second tension spring is installed inside the second collection tank, the third tension spring is installed inside the third collection tank, and the fourth tension spring is installed inside the fourth collection tank. Springs are installed inside the fourth collection tank. The first tension spring has a greater force than the second tension spring, the second tension spring has a greater force than the third tension spring, the third tension spring has a greater force than the fourth tension spring, the fourth tension spring has the same force as the pressure experienced by the fourth collection tank at a seawater depth of 50m, the third tension spring has the same force as the pressure experienced by the third collection tank at a seawater depth of 150m, the second tension spring has the same force as the pressure experienced by the second collection tank at a seawater depth of 250m, and the first tension spring has the same force as the pressure experienced by the first collection tank at a seawater depth of 500m.

[0038] The disassembly components include disassembly bolts 12 and disassembly cover plates 11. The mounting end of the disassembly cover plate 11 is set in a concave arc shape, and the arc surface is provided with anti-slip teeth. The disassembly cover plate 11 is embedded inside the liquid collection rack 6 and fits against the connecting rod 7. The disassembly bolts 12 pass through the disassembly cover plate 11 and are connected to the liquid collection rack 6 by threads. The disassembly cover plate 11 and the liquid collection rack 6 are connected by the disassembly bolts 12, which allows for easy disassembly of the liquid collection rack 6, facilitating subsequent testing of the seawater inside the liquid collection rack 6. The outer wall of the buoyancy plate 30 fits against the inner wall of the liquid collection tank. The middle part of the buoyancy plate 30 has a hollow structure. The buoyancy of the buoyancy plate 30 is much greater than the pressure of the attracting iron plate 29. The buoyancy is greater than the pressure of the attracting iron plate 29, which makes it easier to lift the attracting iron plate 29. The hollow structure in the middle reduces weight and facilitates the entry of seawater into the bottom of the liquid collection tank.

[0039] An electrically controlled power-off switch is installed inside the transparent sealing cover 2. The electrically controlled power-off switch is located between the solar panel 3 and the battery panel 4. The battery panel 4 is connected to a power detector, which is connected to a PLC controller 10. The PLC controller 10 is wirelessly connected to a control terminal. The power detector detects the power of the battery panel 4. When the battery panel 4 is fully charged, the PLC controller 10 controls the electrically controlled power-off switch to cut off the power. When the power is lower than the set value, the PLC controller 10 controls the air inflator 18 to blow air into the buoyancy expansion bag 5 to make the marine surveying frame 1 float and store electricity through the solar panel 3.

[0040] The marine surveying frame 1 has an embedded groove, and the transparent sealing cover 2 is embedded in the embedded groove. The embedded end of the transparent sealing cover 2 and the embedded groove are sealed with waterproof glue. The embedded groove improves the stability of the connection. The connecting rod 7 has a hollow structure inside, and the inner wall of the connecting rod 7 is fixed with reinforcing ribs. The connecting rod 7 has a circuit for connecting the depth sensor 9 and the water quality sensor 13. The hollow structure of the connecting rod 7 facilitates the connection of the circuit and also provides effective waterproofing.

[0041] The implementation principle of the above embodiment is as follows: When mapping seawater, the PLC controller 10 first controls the air inflator 18 to intake air. The air enters the buoyancy expansion bag 5 through the air guide pipe 16 and the one-way valve 15. The buoyancy expansion bag 5 expands and rises. The air pressure information is detected by the air pressure sensor 14. When the air pressure is within the set range, the PLC controller 10 controls the air inflator 18 to cut off the power and place the marine mapping frame 1 on the sea surface. When it floats to a certain position, the PLC controller 10 controls the electric one-way valve 35 to exhaust air and control the marine mapping frame 1 to sink deeper into the ocean. The position information is transmitted to the PLC controller 10 through the position sensor 20 so that the position of the marine mapping frame 1 can be detected in real time. The sinking depth of the marine mapping frame 1 is measured by the depth sensor 9.

[0042] When the marine surveying rig 1 sinks to a certain depth, the tension of the spring 33 becomes less than the pressure of the seawater, causing the sealing plug 31 to move into the collection tank. Seawater enters the collection tank, and the level sensor 34 detects the level information and transmits it to the PLC controller 10. The PLC controller 10 then controls the water quality sensor 13 to perform water quality detection. When seawater enters a set of collection tanks, the buoyancy plate 30 floats upward, causing the attracting iron plate 29 to move upward. As the collection tank gradually fills with liquid, the strong magnetic block attracts the attracting iron plate 29, pushing the sealing plug 31 upward and sealing the collection tank. By varying the tension of the spring 33, seawater at different depths and pressures can be collected and detected. The position of the marine surveying rig 1 is detected by the position sensor 20. When the position deviates from the set range, the PLC controller 10 receives the angle information from the angle sensor, converts the angle information into data information and sends it to the PLC controller 10. The PLC controller 10 controls the rotary motor 19 to rotate. The rotation of the rotary motor 19 drives the angle adjustment shaft 22 to rotate inside the fixed mounting frame 21. The rotation of the angle adjustment shaft 22 drives the adjustment frame 23 to adjust the angle. After the adjustment is completed, the PLC controls the drive motor 26 to work. The drive motor 26 drives the agitator impeller 24 to rotate through the drive shaft 27. The rotation of the agitator impeller 24 drives the marine surveying rig 1 to move, thereby adjusting the position of the marine surveying rig 1.
