Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric field and magnetic field measurement, and particularly relates to a multifunctional ship electric field and magnetic field measuring device. BACKGROUND

[0002] Electric field is a special matter existing in the space around electric charge and changing magnetic field. This matter is different from the usual matter, and it is a special matter existing objectively, although it is not composed of molecules and atoms. The electric field has the force and energy of the usual matter. The force of the electric field is the force acting on the electric charge in the electric field, which is called electric field force. The energy of the electric field is that the electric field force does work on the electric charge when the electric charge moves in the electric field, which shows that the electric field has energy.

[0003] Magnetic field is a physical concept, which refers to the field transmitting the magnetic force between objects. The magnetic field is composed of moving small particles, which cannot be seen and touched under the existing conditions. The magnetic field has the radiation characteristics of particles. There is a magnetic field around the magnet, and the interaction between the magnets is mediated by the magnetic field, so the two magnets can act without physical contact. Since the magnetism of the magnet comes from the electric current, and the electric current is the movement of electric charge, in general, the magnetic field is the strength and speed of the electric field of the moving electric charge relative to the observation point, which brings about the change of the force on the electric charge at the observation point.

[0004] When the ship sails in the sea, it will cause abnormal signals of the surrounding electric field and magnetic field. In order to break through the bottleneck problem of the development of ship detection technology, it is urgent to obtain a large amount of ship physical field signals.

[0005] The existing device has the following disadvantages:

[0006] 1. Since there are many marine organisms in the sea, when the device is located in the sea for a long time, the marine organisms are easy to adhere to the surface of the electric field sensor and the magnetic field sensor, which affects the monitoring performance of the two, that is, the accuracy of the measurement data, for example, some algae.

[0007] 2. The electric field and the magnetic field generated when the ships with different draft depths pass are different, and the overall height of the existing device cannot be adjusted, which reduces the flexibility and accuracy of the measurement.

[0008] 3. Only the bottom plate is in contact with the sea bottom, and the device is easy to shake or overturn at will under the impact of the sea current, which affects the measurement work.

[0009] 4. The structure of the positioning device is not designed, and the device is not designed to automatically rise, which needs to rely on the ship, increasing the cost of deployment and salvage. SUMMARY

The cross-sectional shape of each insert is consistent with that of one clearance notch. The miniature electric push rod is electrically connected to the controller.

[0026] The beneficial effects of this invention are:

[0027] 1. This invention, through the design of a support plate, a waterproof linear motor, a pull block, a swing arm, a top rod, a scraper, a limiting ring, and a buffer spring, addresses the issue that marine life, such as algae, can easily adhere to the surfaces of the electric and magnetic field sensors when the device is submerged in seawater for extended periods, affecting monitoring performance. A pre-set timer program is incorporated within the controller. When the program is activated, the waterproof linear motor is started, causing its output to pull the pull block away from the swing arm. Since the bottom of the swing arm is hinged to the wing plate, the top of the swing arm abuts against one end of the top rod, and the lower half of the swing arm is hinged to the pull block... The top rod is inserted into the support plate, and the top of the scraper is fixedly connected to the end of the top rod away from the swing arm. The two side walls of the scraper are slidably connected to two guide rails respectively, and the bottom of the scraper contacts the top surfaces of the electric field sensor and the magnetic field sensor, thereby causing the scraper to scrape the surfaces of the two sensors and remove the marine organisms attached to them, achieving an automatic cleaning function. This ensures that the electric field sensor and the magnetic field sensor always operate normally and will not have problems with insensitivity, thereby improving the accuracy of the measurement data and the service life of the device. The buffer spring ensures that the scraper slides slowly and prevents excessive force from damaging the surfaces of the electric field sensor and the magnetic field sensor.

[0028] 2. This invention, through the design of an adjustment mechanism, namely a rotating component and two telescopic rods, allows for the detection of electric and magnetic fields of ships with different drafts when it is necessary to detect them. By manually rotating a handwheel, which is fixedly connected to the outer wall of the lead screw, the lead screw is rotated. The lower half of the lead screw is threadedly connected to a sleeve, and the top of the lead screw is rotatably connected to a support sleeve via an insert. Furthermore, the top of the support sleeve is fixedly connected to the bottom of the hull, and the bottom of the sleeve is fixedly connected to the top of the installation compartment. This causes the lead screw to rise and rotate simultaneously, thereby lifting the bottom of the hull. Additionally, the hull is fixedly connected to the tops of the two telescopic rods, allowing the hull to rise synchronously with the two telescopic rods. This adjusts the overall height of the installation compartment and its internal detection mechanism, enabling the detection of electric and magnetic fields of ships with different drafts in the same sea area, thus enhancing the flexibility of the device.

[0029] 3. This invention employs a fixed mechanism, namely a telescopic component and four conical inserts. When the device is deployed on the seabed, i.e., after the circular chassis contacts the seabed, the servo motor is activated by the controller, thereby driving the turntable to rotate. Because the cross rod and the guide rod are slidably connected, and the four conical inserts are fixedly connected to the bottom of the cross rod, and because the outer wall of the turntable and the top of the cross rod are respectively hinged to the two ends of the connecting rod, the cross rod and the four conical inserts at its bottom descend and insert into the seabed soil to achieve a gripping effect. This enhances the stability of the chassis and prevents the device from drifting with the waves and affecting the measurement work.

[0030] 4. This invention, through the design of a partition, a miniature electric push rod, an inverted trapezoidal push block, a mounting rod, a sliding rod, a wedge, inserts, a return spring, and insert strips, addresses the issue that, due to the smooth outer wall of the conical insert, the device is vulnerable to displacement or even pull-out by the turbulent currents in some seabed areas. Therefore, relying solely on four conical inserts is insufficient to secure the chassis. In such cases, after the conical insert penetrates the seabed soil, the controller activates the miniature electric push rod, causing its output end to extend downwards. This, in turn, causes the inverted trapezoidal push block on its output end to slide towards the center of the two inclined blocks. Each insert strip slides along a groove, and each wedge is slidably connected to the mounting rod via two sliding rods. Furthermore, the ends of every two sliding rods furthest from the wedges are connected to three inserts. The device is fixedly connected, and the downward movement of the inverted trapezoidal pusher causes the two wedges to move away from each other, which in turn causes the six inserts to move away from each other and extend from the six clearance notches. A secondary limit is then applied at the part of the conical rod that inserts into the seabed soil. The interpenetration of the conical rod and the six inserts with the seabed soil enhances the grip, preventing instability in areas with strong currents and further improving stability. When retrieving the device, simply retract the output end of the micro-electric pusher via the controller, and the six inserts will retract under the action of the return spring, facilitating the removal of the rod from the seabed soil and enabling the device to be retrieved quickly and easily. This improved grip does not affect subsequent retrieval, enhancing the device's flexibility.

[0031] 5. This invention designs monitoring components, namely magnetic field sensors and electric field sensors, which are used to measure the electric and magnetic fields generated by passing ships and transmit the data to the PC terminal of the control center through the controller, so that the inspection personnel can view and record the measurement data in a timely manner.

[0032] 6. This invention, by designing four thrusters, allows the device to be vertically placed in seawater before measurement work begins. Then, the four thrusters are activated by the controller, ensuring the device maintains a stable descent after entering the water, preventing it from shaking or even flipping. This improves the sinking efficiency and thus the deployment efficiency. Furthermore, by incorporating a GPS sensor, the device is first located during subsequent retrieval. Then, the fans within the four thrusters reverse direction, causing the device to rise from the seabed, further enhancing retrieval efficiency. Attached Figure Description

[0055] Reference Figure 6 As shown, the installation cabin 3 includes a top shell 30 and a bottom shell 31. The bottom shell 31 is fixed between the tops of the two telescopic rods 61. The top shell 30 is fixed to the top of the bottom shell 31 by several bolts. Four thrusters 310 are fixed on the outer wall of the bottom shell 31.

The electrical components contained in the detection mechanism 4 are all installed inside the top shell 30 and the bottom shell 31. The installation cabin 3 has excellent sealing performance, which can effectively prevent seawater from entering and damaging the electrical components. The telescopic assembly 50 and the monitoring assembly 43 are connected to the controller 2 inside the installation cabin 3 through watertight cables. Before the measurement work begins, the device is first placed vertically in the seawater. Then, the four thrusters 310 are activated by the controller 2 to ensure that the device maintains a stable attitude and sinks steadily after entering the water, preventing the device from shaking or even flipping. This helps to improve the sinking efficiency of the device and thus improve the deployment efficiency.

[0056] Reference Figure 7 As shown, the monitoring component 43 includes a magnetic field sensor 430 and an electric field sensor 431. The magnetic field sensor 430 and the electric field sensor 431 are respectively fixed on two wing plates 300 located on the outer wall of the bottom shell 31.

[0057] Reference Figure 5As shown, the power supply assembly 41 includes a battery 410 and a power manager 411. Both the battery 410 and the power manager 411 are fixedly mounted on the top of the mounting plate 40. The battery 410 is electrically connected to the power manager 411, and both the battery 410 and the power manager 411 are electrically connected to the controller 2. The battery 410 supplies power to the power manager 411, and the power manager 411 supplies power to the controller 2. The controller 2 controls the stable operation of each electrical component, thereby ensuring the stable operation and battery life of the entire device.

[0058] Reference Figure 5 As shown, the data processing component 42 includes a sensor signal conditioner 420 and a data acquisition and conversion memory 421. Both the sensor signal conditioner 420 and the data acquisition and conversion memory 421 are fixedly mounted on the top of the mounting plate 40.

[0059] Reference Figure 2 As shown, the telescopic assembly 50 includes a servo motor 500, a connecting rod 501, a turntable 502, and a crossbar 503. The servo motor 500 is fixedly installed inside the sealed chamber 10. The turntable 502 is fitted onto its output end. A guide rod is fixedly installed inside the sealed chamber 10. The crossbar 503 is slidably mounted on the outer wall of the guide rod. The connecting rod 501 is hinged between the outer wall of the turntable 502 and the top of the crossbar 503. Four tapered inserts 51 are fixedly connected to the bottom of the crossbar 503. The servo motor 500 is electrically connected to the controller 2. When this device is deployed to the seabed... After the circular chassis 1 contacts the seabed, the servo motor 500 is started by the controller 2, which drives the turntable 502 to rotate. Since the cross rod 503 is slidably connected to the guide rod, and the four conical rods 51 are fixedly connected to the bottom of the cross rod 503, and since the outer wall of the turntable 502 and the top of the cross rod 503 are respectively hinged to the two ends of the connecting rod 501, the cross rod 503 and the four conical rods 51 at its bottom are driven to descend and insert into the seabed soil to achieve a gripping effect, thereby improving the stability of the chassis and preventing the device from drifting with the waves and affecting the measurement work.

[0060] Reference Figure 4As shown, the rotating assembly 60 includes a sleeve 600, a lead screw 601, a handwheel 602, and a support sleeve 603. The sleeve 600 is fixedly mounted on the top of the sealed chamber 10, and the support sleeve 603 is fixedly mounted on the bottom of the bottom shell 31. The lead screw 601 is threadedly connected to the inside of the sleeve 600. An insert 604 is fixedly mounted on the top of the lead screw 601, and the insert 604 is rotatably connected to the inner wall of the support sleeve 603. The handwheel 602 is fixedly mounted on the outer wall of the end of the lead screw 601 near the support sleeve 603. When it is necessary to detect the electric and magnetic fields of ships with different drafts, the handwheel 602 is manually rotated. Since the handwheel 602 is fixedly connected to the outer wall of the lead screw 601, it drives the lead screw 601 to rotate. The lower half of the rod 601 is threadedly connected to the sleeve 600. The top of the screw 601 is rotatably connected to the support sleeve 603 via the insert 604. Since the top of the support sleeve 603 is fixedly connected to the bottom of the bottom shell 31 and the bottom of the sleeve 600 is fixedly connected to the top of the sealed chamber 10, the screw 601 is driven to rise and rotate, thereby lifting the bottom of the bottom shell 31. In addition, the bottom shell 31 is fixedly connected to the top of the two telescopic rods 61, so that the bottom shell 31 rises synchronously with the two telescopic rods 61. This adjusts the overall height of the installation chamber 3 and its internal detection mechanism 4, so as to detect the electric and magnetic fields of ships with different drafts in the same sea area, thus improving the flexibility of the device.

[0061] Reference Figure 5 As shown, a GPS sensor 400 is also fixedly installed on the top of the mounting plate 40. The GPS sensor 400 is electrically connected to the controller 2. The GPS sensor 400 provides the real-time location of the device, which facilitates subsequent searching and retrieval.

[0062] Reference Figure 9As shown, each wing plate 300 located on the outer wall of the bottom shell 31 has a support plate 311 fixedly installed on its top. A waterproof linear motor 312 is inserted into the support plate 311, and a pull block 313 is fixedly installed on its output end. A swing rod 314 is also hinged to the top of the wing plate 300. The end of the pull block 313 away from the waterproof linear motor 312 is hinged to the lower half of the swing rod 314. A top rod 315 is also slidably installed on the top of the support plate 311. Two guide rails are also fixedly installed on the top of the wing plate 300. A scraper 316 is slidably installed between the two guide rails. The top of the scraper 316 is connected to the top rod 315. One end of the push rod 315 is fixedly connected, and the other end of the push rod 315 abuts against the top of the swing rod 314. A limiting ring 317 is fixedly provided on the outer wall of the end of the push rod 315 near the swing rod 314. A buffer spring 318 is provided between the limiting ring 317 and the support plate 311. The buffer spring 318 is sleeved with the outer wall of the push rod 315. The waterproof linear motor 312 is electrically connected to the controller. Since there are many marine organisms in the ocean, when this device is in seawater for a long time, marine organisms can easily adhere to the surface of the electric field sensor and the magnetic field sensor, affecting the monitoring performance. For example, some algae In this class, a timer program is preset inside the controller 2. When the program starts, the controller 2 starts the waterproof linear motor 312, which in turn drives the pull block 313 to pull away from the end of the swing arm 314. Since the bottom of the swing arm 314 is hinged to the wing plate 300, and the top of the swing arm 314 abuts against one end of the top rod 315, and since the lower half of the swing arm 314 is hinged to the pull block 313, the top rod 315 is inserted into the support plate 311, and the top of the scraper 316 is fixedly connected to the end of the top rod 315 away from the swing arm 314, the two side walls of the scraper 316 are respectively The scraper 316 is slidably connected to two guide rails, and its bottom contacts the top surfaces of the electric field sensor 431 and the magnetic field sensor 430. This allows the scraper 316 to scrape the surfaces of the two sensors, removing marine organisms attached to them. This ensures that the electric field sensor 431 and the magnetic field sensor 430 always operate normally and do not experience any issues with insensitivity. This improves the accuracy of the measurement data and extends the lifespan of the device. The buffer spring 318 ensures that the scraper 316 slides slowly, preventing excessive force from damaging the surfaces of the electric field sensor 431 and the magnetic field sensor 430.

[0063] Working principle: Before the measurement work begins, the device is first placed vertically into the seawater. Then, the four thrusters 310 are activated by the controller 2 to ensure that the device maintains a stable attitude and sinks steadily after entering the water, so as not to shake or even flip the device. This helps to improve the sinking efficiency of the device and thus improve the deployment efficiency.

[0064] Once the device is deployed to the seabed, i.e., after the circular chassis 1 contacts the seabed, the servo motor 500 is activated by the controller 2, thereby driving the turntable 502 to rotate. Since the cross rod 503 is slidably connected to the guide rod, and the four conical insertion rods 51 are all fixedly connected to the bottom of the cross rod 503, and since the outer wall of the turntable 502 and the top of the cross rod 503 are respectively hinged to the two ends of the connecting rod 501, the cross rod 503 and the four conical insertion rods 51 at its bottom are driven to descend and insert into the seabed soil to achieve a gripping effect, thereby improving the stability of the chassis and preventing the device from drifting with the waves and affecting the measurement work.

[0065] When it is necessary to detect the electric and magnetic fields of ships with different drafts, the handwheel 602 is manually rotated. Since the handwheel 602 is fixedly connected to the outer wall of the lead screw 601, the lead screw 601 is rotated. The lower half of the lead screw 601 is threadedly connected to the sleeve 600, and the top of the lead screw 601 is rotatably connected to the support sleeve 603 through the insert 604. Since the top of the support sleeve 603 is fixedly connected to the bottom of the bottom shell 31, and the bottom of the sleeve 600 is fixedly connected to the top of the sealed chamber 10, the lead screw 601 is driven to rise and rotate simultaneously, thereby lifting the bottom of the bottom shell 31. In addition, the bottom shell 31 is fixedly connected to the top of the two telescopic rods 61, so that the bottom shell 31 rises synchronously with the two telescopic rods 61. This adjusts the overall height of the installation chamber 3 and its internal detection mechanism 4, so as to detect the electric and magnetic fields of ships with different drafts in the same sea area, thus improving the flexibility of the device.

[0066] The top shell 30 and the bottom shell 31 are fixedly connected by several bolts, which facilitates disassembly and assembly. The electrical components contained in the detection mechanism 4 are all installed inside the top shell 30 and the bottom shell 31. The installation compartment 3 has excellent sealing performance, which can effectively prevent seawater from entering and damaging the electrical components. The telescopic assembly 50 and the monitoring assembly 43 are both connected to the controller 2 inside the installation compartment 3 through watertight cables.

[0067] The magnetic field sensor 430 and the electric field sensor 431 are used to measure the electric and magnetic fields generated by passing ships and transmit them to the PC terminal of the control center through the controller 2, so that the inspection personnel can view and record the measurement data in a timely manner.

[0068] Because the ocean contains many marine organisms, when this device is submerged in seawater for extended periods, these organisms can easily adhere to the surfaces of the electric and magnetic field sensors, affecting monitoring performance. For example, algae can cause this. A pre-set timer program is installed inside the controller 2. When the program is activated, the controller 2 starts the waterproof linear motor 312, causing its output to pull the block 313 away from the swing arm 314. Since the bottom of the swing arm 314 is hinged to the wing plate 300, and the top of the swing arm 314 abuts against one end of the top rod 315, and the lower half of the swing arm 314 is hinged to the block 313, The top rod 315 is inserted into the support plate 311. The top of the scraper 316 is fixedly connected to the end of the top rod 315 away from the swing rod 314. The two side walls of the scraper 316 are slidably connected to the two guide rails respectively. The bottom of the scraper 316 is in contact with the top surfaces of the electric field sensor 431 and the magnetic field sensor 430, thereby causing the scraper 316 to scrape the surfaces of the two sensors, removing the marine organisms attached to the surfaces. This ensures that the electric field sensor 431 and the magnetic field sensor 430 always operate normally and will not have the problem of insensitivity, thereby improving the accuracy of the measurement data and the service life of the device.

[0069] The sensor signal conditioner 420 is used to condition the measured electric and magnetic field signals, while the data acquisition and conversion memory 421 is used to acquire and store the measured electric and magnetic field signals to improve the accuracy of the measurement data.

[0070] Battery 410 is used to supply power to power manager 411, which in turn supplies power to controller 2. Controller 2 controls the stable operation of various electrical components, thereby ensuring the stable operation and battery life of the entire device.

[0071] The GPS sensor 400 provides the real-time location of the device, which, in conjunction with the four thrusters 310, facilitates the subsequent positioning and retrieval of the device.

[0072] Example 2

[0073] Reference Figure 11 and Figure 12As shown, to improve the grip of the four insert rods and further enhance the stability of the chassis, each tapered insert rod 51 has an internal mounting hole. A partition 7 is fixedly installed on the inner wall of the mounting hole. A miniature electric push rod 70 is inserted into the top of the partition 7, with its output end passing through the partition 7 and an inverted trapezoidal push block 71 fixedly installed on its output end. Two mounting rods 72 are symmetrically arranged on the inner wall of the mounting hole. Two sliding rods 73 are inserted into each mounting rod 72. A wedge block 74 is fixedly installed at one end of the two sliding rods 73, and three insert pieces 75 are fixedly installed at the other end of the two sliding rods 73. A return spring 76 is sleeved on the outer wall of each sliding rod 73. The mounting rods 72 and the wedge blocks 74 are... 4. Each wedge 74 abuts against both ends of each return spring 76. Two inserts 77 are fixedly provided at both ends of the inverted trapezoidal push block 71. Each wedge 74 has a groove on the outer wall near the end of the inverted trapezoidal push block 71 for the inserts 77 to slide. Six clearance notches are symmetrically arranged on the outer wall of the mounting rod 72 in the circumferential direction. Each insert 75 has the same cross-sectional shape as one clearance notch. The miniature electric push rod 70 is electrically connected to the controller 2. Since the outer wall of the tapered insert 51 is smooth, when deploying this device in some sea areas with strong currents, the strong currents may cause the insert to shift or even be pulled out. Therefore, relying solely on four tapered inserts 51 is far from sufficient to fix the chassis. When this situation occurs, after the conical insert 51 penetrates the seabed soil, the micro electric push rod 70 is activated by the controller 2, causing its output end to extend downwards. This causes the inverted trapezoidal push block 71 on its output end to slide towards the middle position of the two inclined blocks. Since each insert 77 slides with a groove, and each wedge 74 is slidably connected to the mounting rod 72 via two sliding rods 73, and since the ends of each pair of sliding rods 73 away from the wedge 74 are fixedly connected to three insert pieces 75, the opposing force of the inverted trapezoidal push block 71 on the two wedges 74 when it descends causes the two wedges 74 to move away from each other, thereby causing the six insert pieces 75 to move away from each other. Six clearance notches extend out to further limit the position of the tapered rod 51 when it is inserted into the seabed soil. The tapered rod 51 and the six inserts 75 interpenetrate with the seabed soil to improve the gripping effect and prevent the device from being unstable in the sea with strong currents. This further improves the fixation effect. When the device is removed, the controller 2 simply drives the output end of the micro electric push rod 70 to retract. Under the action of the return spring 76, the six inserts 75 are retracted, making it easy to pull the rod out of the seabed soil and retrieve the device. This is convenient and quick. While improving the gripping effect of the device, it does not affect the subsequent retrieval of the device, thus improving the flexibility of the device.
