Description

Technical Field

[0001] This invention relates to the field of marine surveying technology, specifically to a marine engineering marine surveying device with positioning function. Background Technology

[0002] As humanity has entered an industrialized society, industrial development has led to an increasingly severe dependence on non-renewable resources. The depletion of non-renewable resources on land has become a growing problem, making the need for resource development urgent. People have begun to focus on the ocean, which covers the vast majority of the Earth's surface, indicating its extremely rich resources. Before developing these abundant marine resources, marine environmental exploration is a crucial preparatory step. During marine environmental exploration, personnel use various equipment to collect seabed soil samples, seawater samples, monitor ocean current changes, and monitor marine species. Long-term, continuous, and fixed-point detection of the marine hydrological environment, especially the real-time detection of a series of marine hydrological parameters such as seabed depth, seawater density, and ocean current velocity, is a challenging, complex, and significant task. Seawater current velocity is a crucial aspect of marine surveying engineering. Understanding the patterns of seawater flow not only serves national defense, maritime transportation, fisheries, and port construction, but it is also closely related to research in other fields of marine science.

[0003] However, existing marine engineering surveying products still have many shortcomings in use. Most are only suitable for shallow water environments, and in the ocean, they are easily pushed away from the surveying location by the water flow caused by ocean currents, making it difficult to perform positioning operations and thus affecting the final surveying data. Therefore, it is necessary to propose a new marine engineering surveying device with positioning function. Summary of the Invention

[0004] The purpose of this invention is to provide a marine engineering waterborne surveying device with positioning function, in order to solve the problem that most existing marine engineering waterborne surveying products mentioned in the background art are only applicable to shallow water environments, and are easily pushed away from the surveying location by the water flow fluctuations generated by ocean currents, making it difficult to perform positioning operations, which in turn easily affects the final surveying data.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a marine engineering waterborne surveying device with positioning function, comprising a waterproof shell, laser beam emitters spaced apart on the outer periphery of the waterproof shell, a color-developing coating on the top outer wall surface of the waterproof shell, and a GPRS chip installed on the top wall surface of the waterproof shell; wherein, a driving power supply is installed inside the waterproof shell, a microprocessor is electrically connected to the top output terminal of the driving power supply, a current meter is electrically connected to the side of the microprocessor via a line, a signal transmitter is connected to the surface of the microprocessor via a line, a filter is connected to the side of the signal transmitter via a line, a coordinator is electrically connected to the side of the filter via a line, a radio transmitter is electrically connected to the side of the coordinator via a line, a receiver is connected to the side of the radio transmitter via a line, and a capacitor is electrically connected to the side of the driving power supply via a line; the connection terminals of the driving power supply and the capacitor are connected in series. A positive feedback circuit is electrically connected to an oscillator, and the side end of the oscillator is plugged into the connection terminal of the microprocessor. A voltage regulator is connected to the left side surface of the microprocessor via a circuit, and the voltage regulator is electrically connected to the drive power supply via a circuit. A shielding mounting bracket is securely mounted on the top surface of the waterproof housing. A signal amplifier is installed inside the bottom end of the shielding mounting bracket. An aluminum ring plate is welded to the top wall surface of the shielding mounting bracket, and a microwave antenna is installed at the center end of the shielding mounting bracket. The microwave antenna is connected to the radio transmitter. A buoyancy sensor is installed on the outer periphery of the bottom connecting pipe of the waterproof housing.

A self-driving adjustment component is installed inside the water-proof cover.

[0006] Preferably, the self-driven adjustment assembly includes a brushless motor, a fixed mounting plate is tightly fastened to the outside of the brushless motor, a first connecting joint is externally connected to the output shaft of the brushless motor, a second connecting joint is connected to the front end of the first connecting joint, a connecting block is connected to the front end of the second connecting joint, a swivel joint is connected to the side end of the connecting block, a swing frame is installed inside the connecting block, a connecting shaft is fastened to the inner wall of the front end of the swing frame's fish-ring mounting seat, a movable adjustment block is externally connected to the connecting shaft, a connecting short shaft is provided at the surface axial center end of the movable adjustment block, and the connecting short shaft is connected and installed with the swivel joint. A carbon fiber swing fin is installed at the connection end of the movable adjustment block and the connecting shaft. The adjustment is started by the speed of the brushless motor. In conjunction with the first and second connecting sections, the shaft joint drives the movable adjustment block and the connecting short shaft to swing back and forth inside the swing frame. This facilitates the driving of the carbon fiber swing fin for swinging operation. When the overall device is deviated by the potential energy of ocean currents, the swinging property of the carbon fiber swing fin can be used to control the swinging of the overall device to the opposite position of the deviated direction. The swinging force and the force of the water potential energy are canceled out, which facilitates the static operation of the overall device at the survey position.

[0007] Preferably, a timing controller is installed inside the self-driving housing. The timing controller is connected to the brushless motor control via a circuit, and is also electrically connected to the microprocessor via a circuit. When the brushless motor needs to be used for operation, a control signal can be sent to the timing controller with the cooperation of the microprocessor, so that the timing controller can control and adjust the start of the four sets of brushless motors.

[0008] Preferably, the bottom of the floating disc is connected to a chamber, inside which a miniature high-pressure submersible pump is installed. A high-pressure regulating port is located on the outer periphery of the chamber. The opening and closing of the high-pressure regulating port is controlled by an electric butterfly valve. The miniature high-pressure submersible pump facilitates the discharge of water through the regulating port. Simultaneously, the potential energy generated by the discharge is directed in the opposite direction to the water flow, further ensuring the stability of the overall device's measurement. Furthermore, the high-pressure regulating port allows for control and adjustment of the water depth within the chamber, preventing excessive water intake that could cause the overall device's weight to exceed its buoyancy, resulting in sinking and damage.

[0009] Preferably, a water inlet regulating port is provided on the bottom surface of the chamber. The water inlet regulating port is connected to the micro high-pressure submersible pump. With the cooperation of the water inlet regulating port, it is convenient to carry out water intake into the chamber and ensure the stability of the whole device when operating on the water surface.

[0010] Preferably, the bottom end of the miniature high-pressure submersible pump is connected to a center-of-gravity rod, and the bottom end of the center-of-gravity rod is connected to a sampling and mapping head. With the cooperation of the center-of-gravity rod, it is easy to ensure the center-of-gravity position of the whole device during operation and prevent the whole device from tipping over during operation.

[0011] Preferably, a rotating shaft seat is fastened to four ends of the outer wall of the waterproof housing. A micro angle adjustment motor is mounted on the outside of the rotating shaft seat. A damping rotating shaft column is installed at the center end of the rotating shaft seat. The output shaft of the micro angle adjustment motor is connected to the damping rotating shaft column. The micro angle adjustment motor facilitates the adjustment of the angle of the damping rotating shaft column within the rotating shaft seat when the liquid level of the entire device is below the liquid level rod.

[0012] Preferably, a liquid level rod is hinged to the outer circumference of the damping shaft column, and a solar photovoltaic panel is embedded in the front end of the liquid level rod. The bottom end of the solar photovoltaic panel is electrically connected to the drive power supply through a photovoltaic inverter. The use of the solar photovoltaic panel effectively ensures the continuous operation of the entire device.

[0013] Preferably, low-frequency signal generators are installed on both sides of the outer side of the waterproof cover, and the low-frequency signal generators are electrically connected to the capacitors through lines. With the cooperation of the low-frequency signal generators, the whole device can transmit low-frequency signals in a timely manner after the surveying work, which further ensures the signal positioning work during the surveying of the whole device.

[0014] Preferably, a rotary valve overflow end is installed on the four sides of the self-driving housing. The bottom of the rotary valve overflow end is connected to a check pipe. The bottom end of the check pipe passes through the float and the chamber. With the cooperation of the rotary valve overflow end and the check pipe, when the water level is higher than the rotary valve overflow end, the rotary valve opens and draws water into the chamber, further ensuring that the weight and buoyancy are proportional when the whole device is in operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, by coordinating a signal transmitter, filter, coordinator, radio transmitter, GPRS chip, and microwave antenna, radio skywave and groundwave transmissions are achieved. Furthermore, the combination of a signal amplifier and an aluminum ring plate enhances the stability of the signal transmission band, preventing interference from surrounding signal sources and improving signal positioning accuracy. Simultaneously, a self-oscillating circuit is formed by a capacitor, positive feedback circuit, and oscillator to generate pulse signals, further strengthening positioning accuracy. Additionally, the low-frequency signal generator allows the entire device to periodically transmit low-frequency signals after surveying operations, further ensuring signal positioning during surveying. Subsequently, a laser beam emitter can be used to create periodic laser beam illumination at night. Furthermore, the use of a color-developing coating facilitates more accurate positioning of the entire device by surveyors, resulting in higher retrieval efficiency. This reduces the risk of the device being easily shifted from its surveying location by ocean currents, hindering positioning operations and preventing impact on the final survey data.

[0017] 2. In this invention, with the cooperation of the self-driven adjustment component, when encountering a large water flow, a conversion signal is sent to the microprocessor in conjunction with the flow meter. This causes the microprocessor to send a control signal to the timing controller, which then controls and adjusts the start-up of the four brushless motors. After receiving the control signal, the brushless motors start and adjust using their rotational speed. In conjunction with the first and second connecting sections, the shaft joint drives the movable adjustment block and the connecting short shaft to perform reciprocating swinging operation inside the swing frame. This facilitates the driving of the carbon fiber swing fins for swinging operations. When the overall device shifts due to the potential energy of ocean currents, the swinging property of the carbon fiber swing fins can be used to control the device to swing in the opposite direction of the shift. The swinging force and the force of the water potential energy cancel each other out, thus facilitating the static operation of the overall device at the surveying location.

[0018] 3. In this invention, by using a high-pressure regulating port, a miniature high-pressure submersible pump, a buoyancy sensor, a water inlet regulating port, and a rotary valve overflow end, the miniature high-pressure submersible pump facilitates the discharge of water through the high-pressure regulating port. Simultaneously, the potential energy generated by the discharge is directed in the opposite direction to the water flow potential energy, further ensuring the stability of the overall device measurement. Furthermore, the high-pressure regulating port facilitates the control and adjustment of the water depth within the chamber, preventing excessive water intake that could cause the overall device weight to exceed buoyancy, resulting in sinking and damage. Additionally, with the assistance of the buoyancy sensor, the overall device, under the control of the microprocessor, ensures that the liquid level during placement and operation remains within the safety threshold.

[0019] 4. In this invention, the combination of a miniature ultrasonic sonar, a miniature angle adjustment motor, a damping shaft column, and a solar photovoltaic panel facilitates the driving of fish, preventing collision damage to the overall device caused by the fish's movement. Furthermore, the miniature angle adjustment motor allows the damping shaft column to be angled within the shaft seat, simultaneously extending the liquid level rod and the solar photovoltaic panel. This enables the solar photovoltaic panel to better perform solar energy conversion, ensuring the overall device's operational sustainability. Finally, a sampling and mapping head is used for sampling and mapping operations. Attached Figure Description

[0032] according to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the self-driven adjustment assembly 17 includes a brushless motor 171.

[0034] according to Figure 1 and Figure 4 As shown, a chamber is installed at the bottom of the floating plate 19. A miniature high-pressure submersible pump 27 is installed inside the chamber, and a high-pressure regulating port 20 is opened on the outer wall of the chamber. The opening and closing of the high-pressure regulating port 20 is controlled by an electric butterfly valve. The miniature high-pressure submersible pump 27 facilitates the discharge of water through the high-pressure regulating port 20. At the same time, the potential energy generated by the discharge is in the opposite direction to the driving direction of the water flow potential energy, which further ensures the stability of the overall device measurement. The high-pressure regulating port 20 also facilitates the control and adjustment of the water depth inside the chamber, avoiding excessive water intake, which would cause the weight of the overall device to exceed the buoyancy, resulting in the overall device sinking and being damaged.

[0037] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a rotating shaft seat 2 is fastened to the four ends of the outer wall of the waterproof housing 1. A micro angle adjustment motor 3 is mounted on the outside of the rotating shaft seat 2. A damping rotating shaft column 4 is installed at the center end of the rotating shaft seat 2. The output shaft of the micro angle adjustment motor 3 is connected to the damping rotating shaft column 4.

The appropriate model should be selected based on actual use. Therefore, the control methods and wiring layouts of the following components will not be explained in detail: miniature angle adjustment motor 3, laser beam emitter 7, signal amplifier 9, microwave antenna 11, buoyancy sensor 12, rotary valve overflow terminal 14, low frequency signal generator 16, brushless motor 171, miniature ultrasonic sonar 18, GPRS chip 24, miniature high-pressure submersible pump 27, microprocessor 28, capacitor 30, signal transmitter 31, filter 32, coordinator 33, oscillator 34, voltage regulator 35, receiver 36, and timing controller 37.

[0042] The usage and working principle of this device are as follows: First, when conducting marine engineering surveying operations, surveyors can deploy the entire device at a fixed point. After deployment, the miniature high-pressure submersible pump 27 starts, facilitating water intake into the chamber with the help of the water inlet regulating port 23. This initially ensures the stability of the device on the water surface, making the weight and buoyancy of the device proportional. Then, with the help of the miniature angle adjusting motor 3, the damping shaft column 4 is driven to adjust its angle within the shaft seat 2. Simultaneously, the liquid level rod 5 and the solar photovoltaic panel 6 are extended, allowing the solar photovoltaic panel 6 to better perform solar energy conversion and ensuring the continuous operation of the entire device. Next, the sampling and mapping head 22 is used to collect samples. In the mapping operation, when encountering significant water flow, a conversion signal is sent to the microprocessor 28 in conjunction with the current meter. This microprocessor 28 then sends a control signal to the timing controller 37, which controls and adjusts the starting of the four brushless motors 171. Upon receiving the control signal, the brushless motors 171 adjust their speed, coordinating with the first connecting joint 173 and the second connecting joint 174 to cause the shaft joint 178 to drive the movable adjusting block 179 and the connecting short shaft 1790 in a reciprocating swing motion within the swing frame 175. This facilitates the driving of the carbon fiber swing fin 1791 for swinging operations. This allows for adjustments when the overall device shifts due to the potential energy of ocean currents. The oscillating property of the carbon fiber oscillating fin 1791 controls the oscillation of the entire device in the opposite direction of offset. The oscillation force and the water potential energy cancel each other out, facilitating static operation at the surveying location. Simultaneously, a miniature high-pressure submersible pump 27 facilitates water discharge through the high-pressure regulating port 20. The potential energy generated by the discharge further opposes the pushing direction of the water flow potential energy, ensuring the stability of the overall surveying operation. The high-pressure regulating port 20 also allows for control and adjustment of the water depth within the chamber, preventing excessive water intake that could cause the device's weight to exceed buoyancy, resulting in sinking and damage. Furthermore, with the assistance of the buoyancy sensor 12, the entire device, under the control of the microprocessor 28, ensures the overall stability of the surveying operation. When the liquid level in the device is placed during operation, it is within the safety threshold. After sampling and mapping, radio skywaves and groundwaves are transmitted in conjunction with the signal transmitter 31, filter 32, coordinator 33, radio transmitter, GPRS chip 24, and microwave antenna 11. The signal amplifier 9 and aluminum ring plate 10 enhance the stability of the signal transmission band, preventing interference from surrounding signal sources and improving signal positioning accuracy. Simultaneously, a self-oscillating circuit is formed with the capacitor 30, positive feedback circuit, and oscillator 34 to generate pulse signals, further enhancing positioning accuracy. Furthermore, the low-frequency signal generator 16 allows the entire device to periodically transmit low-frequency signals after mapping operations.To further ensure signal positioning during the overall device surveying, the laser beam emitter 7 can then be used to create phased laser beam illumination at night. Combined with the color-developing paint, this facilitates more accurate positioning of the overall device and improves retrieval efficiency. Furthermore, during the overall device surveying process, the installed miniature ultrasonic sonar 18 can be used to drive away schools of fish, preventing them from colliding and damaging the device.
