Description

Technical Field

[0001] The present invention relates to the technical field of marine ecological monitoring, and specifically, to an automatic online monitoring buoy system for marine profiles. Background Art

[0002] With the increasing maturity of profiling technologies, combined with data acquisition and telemetry marine buoy systems and marine environmental water resource management monitoring platform software, it is possible to achieve automatic online monitoring of water quality profiles in different water bodies such as the ocean, estuaries, and coastal waters, effectively and real-time monitoring various changes in the water body, and providing reliable analysis and monitoring for the effective management of water ecology, water environment, and water safety.

[0003] Traditional water quality observations rely on hanging a string of expensive instruments on moored subsurface buoys or surface buoys, which are costly, complex to deploy, and the data can generally only be retrieved and downloaded after several months, with relatively high risks. In recent years, due to reasons such as the complexity of the system, high construction costs, great technical difficulties, and high operation and maintenance costs, it has been rather difficult to carry out large-scale site construction for water quality vertical profile automatic online monitoring buoy systems.

[0004] The main function of the water quality vertical profile measurement system platform is to control the instrument to move up and down in the water and conduct autonomous underwater profile measurements, capable of long-term, continuous, multi-layer, and multi-element collection of marine environmental data. It can carry a variety of sensors, including CTD, current meters, multi-parameter sensors, fluorometers, turbidity meters, and various chemical sensors.

[0005] Existing automatic online monitoring buoy systems for marine profiles use instrument brackets to carry instruments and lower the instrument brackets into the sea through winches and cables. The instrument brackets will rotate, swing, etc. under the influence of ocean currents, causing great stress on the cables. Additionally, how to reduce the influence of ocean currents is also an important issue.

[0006] Existing instrument brackets will swing or rotate, etc. under the sea surface under the influence of ocean currents, causing great torsion on the cables. Especially when rising, the existence of great torsion often easily causes the cables to break, resulting in problems such as instrument loss.

[0007] When existing automatic online monitoring buoy systems for marine profiles retrieve the cables, due to some large turning angles on the equipment, when the cables come into contact with the turning angles, a great deal of friction is formed, and it is difficult for the motor to pull the cables.

[0008] Existing automatic online monitoring buoy systems for marine profiles only use solar power supply. In winter or on rainy and cloudy days, due to insufficient sunlight, the system power is low, and it may even be unable to work. Summary of the Invention

[0009] The technical problem solved by the present invention is to overcome the defects of the prior art and provide an automatic online monitoring buoy system for ocean profiles.

[0010] The purpose of the present invention is achieved through the following technical solutions:

[0011] An automatic online monitoring buoy system for ocean profiles comprises a floating body, a wind power generation system, and an instrument bracket for carrying instruments, wherein the instrument bracket is connected to a winch start-stop device via a cable;

[0012] The instrument bracket comprises a shuttle-shaped frame composed of 2 to 4 brackets, a guard plate is provided at the upper end of the shuttle-shaped frame, and the guard plate is connected to the counterweight block on the cable; a tensile member is provided on the shuttle-shaped frame, and the cable is fixed on the tensile member in an S-shaped arrangement;

[0013] The winch start-stop device comprises a winch bracket arranged vertically, a drive shaft arranged on the winch bracket through a bearing, a drum for winding up the cable is arranged on the drive shaft, and the drive shaft is driven by a winch motor;

[0014] A magnetic induction sensor is arranged below the drum, and a permanent magnet is arranged on the cable. When the permanent magnet approaches the magnetic induction sensor, a control signal is sent out to control the start and stop of the winch motor;

[0015] The floating body is provided with a through hole for installing instruments and / or storing and releasing instruments, and the through hole is provided with a chamfer.

[0016] By setting the chamfer, the friction can be reduced when the cable contacts the corner, so that the cable can be pulled easily.

[0017] By placing the cable in an S-shape on the tension-resistant piece, the outer sheath of the cable is tightly held with the conductor, and the tension is dispersed throughout the line segment, avoiding the outer sheath or conductor being stressed and causing the core to separate, or even causing the cable to break. By clamping the counterweight on the cable through the guard plate, the gravity of the instrument and other counterweights is also dispersed to the cable, avoiding the cable and instrument joints from breaking.

[0018] The magnetic induction sensor is used as a signaling device for the travel position, and the permanent magnet on the cable is used as a moving part. Once it approaches the magnetic induction sensor, it can attract and send a signal. The signal line connected to the magnetic induction sensor is connected to the controller. When the magnetic sensor signal is received, the winch motor is directly controlled to start and stop. It overcomes the lag time (1~2 seconds) brought by the existing start-stop control scheme, and the problem of the motor driving the instrument bracket to hit the equipment and cause damage. It has the advantages of fast response time and reliable control scheme.

[0019] Furthermore, the tensile member is connected to the shuttle-shaped frame through a U-shaped member; the open end of the U-shaped member is connected to the tensile member, and the bottom is connected to the mounting plate of the shuttle-shaped frame through a screw.

[0020] Furthermore, the tensile member is composed of two plates symmetrically provided with S-shaped grooves, forming an S-shaped channel for clamping the cable.

[0021] Furthermore, a hoop for fixing the instrument is provided on the shuttle-shaped frame; an ocean current guide plate is provided at the lower part of the shuttle-shaped frame, and a weight hanging hole is provided at the bottom end.

[0022] Furthermore, the magnetic induction sensor is provided with a through hole through which the permanent magnet on the cable can pass. The cable passes through the through hole. On the one hand, it can ensure that the permanent magnet can contact the magnetic induction sensor, and on the other hand, it adds a limiting function, increasing the stability of the cable retracting and releasing process.

[0023] The depth of the instrument being lowered is monitored by a pressure sensor. When lowering or recovering, the water depth and so on are continuously detected. If the water depth does not change, the instrument is stopped from being lowered.

[0024] However, due to the action of ocean currents, the instrument support may tilt or deviate from the vertical position without actually reaching the corresponding water depth. Therefore, the inclination angle of the instrument is monitored by an inclination sensor to analyze whether it deviates from the position, etc.

[0025] Furthermore, the chamfer size of the through hole is 30° - 45°. Preferably, the chamfer is an arc chamfer.

[0026] Furthermore, the wind power generation system includes a wind blade, a mounting seat for mounting the wind blade, and a vertical axis wind turbine. The electricity generated by the wind power generation system is incorporated into the storage battery of the power supply system to ensure that the equipment operates normally when the voltage is above 12V or 24V.

[0027] Furthermore, it also includes a safety marking device integrating a radar reflector, a lightning rod, and an X mark. Through integration, the space waste on the equipment is avoided.

[0028] Furthermore, it also includes a support frame arranged at the bottom of the floating body, and an anchor chain is connected to the support frame. Through the support frame, the damage to the buoy system caused by collision can be effectively prevented. On the other hand, the support frame plays a role in counterweight, making the buoy system more stable and improving the anti-wind and wave resistance.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] In the present invention, the cable is arranged in an S shape on the tensile resistance member, so that the outer sheath of the cable is tightly held against the conductor, and the tensile force is dispersed over the entire line segment, avoiding the separation of the outer sheath or the conductor due to the applied force, and even the breakage of the cable. The counterweight on the cable is clamped by the guard plate, which also disperses the gravity of the instrument and other counterweights onto the cable, avoiding the breakage at the joint between the cable and the instrument.

[0031] With the magnetic induction sensor as the signal sending device for the travel in place, and the permanent magnet on the cable as the moving part, once it approaches the magnetic induction sensor, it can make it attract and send a signal. The signal wire connected to the magnetic induction sensor is connected to the controller, and when receiving the signal from the magnetic induction sensor, it directly controls the start and stop of the winch motor. This overcomes the problems such as the damage caused by the instrument bracket driven by the motor hitting the equipment during the lag time (1 - 2 seconds) brought by the existing start and stop control schemes. It has the advantages of fast response time and reliable control scheme.

[0032] The wind power generation system is incorporated into the storage battery of the power supply system to ensure the normal operation of the equipment at voltages above 12V or 24V, forming a wind-solar complementary power supply system. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment 1

[0040] As Figures 1 to 5As shown, an automatic online monitoring buoy system for ocean profiles includes a floating body 6, a wind power generation system 7, and an instrument bracket for carrying instruments, wherein the instrument bracket is connected to a winch start-stop device via a cable 13;

[0041] The instrument support comprises a shuttle-shaped frame composed of 2 to 4 supports 4, a guard plate 41 is provided at the upper end of the shuttle-shaped frame, and the guard plate 41 is connected to the counterweight block 132 on the cable; a tensile member 5 is provided on the shuttle-shaped frame, and the cable 13 is fixed on the tensile member 5 in an S-shaped arrangement;

[0042] The winch start-stop device comprises a winch bracket 1 arranged vertically, a drive shaft 12 arranged on the winch bracket 1 through a bearing 11, a drum 14 for winding up a cable 13 is arranged on the drive shaft 12, and the drive shaft 12 is driven by a winch motor 15;

[0043] A magnetic induction sensor 2 is provided below the drum 14, and a permanent magnet 131 is provided on the cable 13. When the permanent magnet 131 approaches the magnetic induction sensor, a control signal is sent to control the start and stop of the winch motor 15;

[0044] The floating body 6 is provided with a through hole 61 for installing instruments and / or storing and releasing instruments, and the through hole is provided with a chamfer 62 .

[0045] By providing the chamfer 62 , when the cable 13 contacts the corner, the friction force can be reduced, so that the cable can be easily pulled.

[0046] By arranging the cable 13 in an S-shape on the tension-resistant member 5, the outer sheath of the cable 13 is tightly held with the conductor, and the tension is dispersed in the entire line segment, avoiding the outer sheath or conductor being stressed and causing the core to separate, or even causing the cable to break. The counterweight 132 on the cable is clamped by the guard plate 41, and the gravity of the instrument and other counterweights is also dispersed to the cable, avoiding the cable and the instrument from breaking at the joint.

[0047] The magnetic induction sensor 2 is used as a signaling device for reaching the travel position, and the permanent magnet 131 on the cable 13 is used as a moving part. Once it approaches the magnetic induction sensor 2, it can attract and send a signal. The signal line connected to the magnetic induction sensor 2 is connected to the controller. When the magnetic sensor signal is received, the winch motor 15 is directly controlled to start and stop. It overcomes the lag time (1 to 2 seconds) brought by the existing start-stop control scheme, and the problem of the motor driving the instrument bracket to hit the equipment and cause damage. It has the advantages of fast response time and reliable control scheme.

[0048] The tensile resistance member 5 is connected to the shuttle-shaped frame through the U-shaped member 42. The open end of the U-shaped member 42 is connected to the tensile resistance member 5, and the bottom is connected to the mounting plate of the shuttle-shaped frame through a screw. Fixing the tensile resistance member through the U-shaped member 5 can, on the one hand, cleverly avoid the rotation of the tensile resistance member under the influence of factors such as ocean currents, so as to prevent the cable from being subjected to torsion; on the other hand, it adds a tensile force bearing point between the protective plate and the instrument, dispersing the gravity of the instrument and the instrument bracket.

[0049] The tensile resistance member 5 is composed of two plates symmetrically provided with S-shaped grooves, forming an S-shaped channel for clamping the cable.

[0050] The shuttle-shaped frame is provided with a hoop 43 for fixing the instrument; the bottom end is provided with a counterweight hanging hole 44 or a counterweight. The instrument is installed through at least one hoop to achieve a stable installation.

[0051] The lower part of the shuttle-shaped frame is provided with an ocean current guide plate 45. Through the ocean current guide plate 45, the instrument bracket can well overcome the irregular swinging or rotation caused by ocean currents under the sea surface, reducing the torsion force on the cable.

[0052] The magnetic induction sensor 2 is provided with a through hole, and the permanent magnet 131 on the cable 13 can pass through the through hole. The cable passing through the through hole can, on the one hand, ensure that the permanent magnet can contact the magnetic induction sensor, and on the other hand, add a limiting function, increasing the stability of the cable during the winding and unwinding process.

[0053] The magnetic induction sensor 2 is circular ring-shaped, and a groove 21 is provided on the outer circumference of the circular ring. Since the cable 13 will move left and right during the process of winding and unwinding the cable, the magnetic induction sensor 2 should also be able to move left and right. Through the circular ring design and the cooperation of the groove 21 on the outer circumference of the circular ring and the slotted plate 22, during the left and right movement of the cable, the bending angle of the cable can be reduced, thereby reducing the frictional resistance and the stress of the cable, etc., so as to prevent the cable from breaking.

[0054] The magnetic induction sensor 2 is limited in movement by a horizontally arranged slotted plate 22, the groove 21 is adapted to the slotted plate 22, and the slotted plate 22 is provided with a long strip U-shaped groove, and a limiting baffle 23 is provided at the open end of the U-shaped groove.

[0055] The slotted plate 22 is arranged on the winch bracket 1 through the side plate 24. The slotted plate 22 and the side plate 24 are connected at 90°, and a reinforcing rib 25 is provided between the two.

[0056] Buffer blocks 26 are provided on the upper and lower surfaces of the magnetic induction sensor 2. Through the buffer blocks 26, on the one hand, the magnetic induction sensor can be protected, and on the other hand, the bending degree of the cable can be reduced.

[0057] A guiding lead screw 3 is arranged between the lower part of the reel 14 and above the magnetic induction sensor 2, and the guiding lead screw 3 is arranged on the winch bracket 1 through bearings 31 at both ends.

[0058] The guiding lead screw 3 is provided with a slip ring pulley assembly 32 and a cross bar 33. The slip ring pulley assembly 32 is driven by the guiding lead screw 3 to move left and right. The cooperation of the guiding lead screw 3, the slip ring pulley assembly 32 and the cross bar 33 realizes the function of guiding the cable.

[0059] One end of the driving shaft 12 is provided with a first synchronous pulley 16, and one end of the guiding lead screw 3 is provided with a second synchronous pulley 17. The first synchronous pulley 16 and the second synchronous pulley 17 move synchronously through a belt.

[0060] A belt tensioning device 18 is provided on the winch support 1. The belt tensioning device 18 is provided with a long strip through hole passing through the belt, and a tensioning pulley is arranged on the through hole, and the tensioning pulley is adjusted along the horizontal direction.

[0061] The depth of the instrument lowered is monitored by a pressure sensor. When lowering or recovering, the water depth and the like are continuously detected. If the water depth does not change, the instrument is stopped from being lowered.

[0062] However, due to the action of ocean currents, the instrument support may tilt or deviate from the vertical position without actually reaching the corresponding water depth. Therefore, the inclination angle of the instrument is monitored by an inclination sensor to analyze whether it deviates from the position and the like.

[0063] The size of the chamfer of the through hole 61 is 30° - 45°. Preferably, the chamfer 62 is an arc chamfer.

[0064] The wind power generation system 7 includes a wind blade 71, a mounting seat for mounting the wind blade, and a vertical axis wind turbine. The electricity generated by the wind power generation system is incorporated into the storage battery of the power supply system to ensure that the equipment works normally when the voltage is above 12V or 24V.

[0065] It also includes a safety marking device integrating a radar reflector 81, a lightning rod 82 and an X mark 83. Through integration, the space waste on the equipment is avoided.

[0066] It also includes a support frame 9 arranged at the bottom of the floating body 6, and an anchor chain 91 is connected to the support frame 9. Through the support frame 9, the damage to the buoy system caused by collision can be effectively prevented. On the other hand, the support frame plays a role of counterweight, making the buoy system more stable and improving the anti-wind and wave ability.

[0067] Obviously, the above embodiments are only examples for clearly explaining the technical solutions of the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
