Description

Technical Field

[0001] This utility model specifically relates to a self-stabilizing monitoring buoy, belonging to the field of shipping monitoring. Background Technology

[0002] In shipping monitoring, monitoring buoys are multifunctional devices with crucial functions. Equipped with a GPS module, they can locate a vessel's latitude and longitude coordinates in real time and transmit this location information back to the monitoring center. Simultaneously, they record the vessel's navigation trajectory, helping to optimize routes and trace accident paths. Furthermore, the buoy can sense the approach of the vessel to other ships or dangerous areas, combining this information with speed and heading to assess collision risks and issue warnings. It can also monitor changes in the marine environment, such as weather conditions and pollutant leaks, issuing timely early warning signals.

[0003] In ship condition monitoring, buoys can connect to critical ship equipment, collect operational data, determine whether the equipment is functioning properly, and monitor the status of special cargoes, such as the pressure and temperature of storage tanks on liquefied natural gas carriers, ensuring cargo safety. In emergency rescue, buoys can automatically transmit last known location information when a ship is in distress, providing a target for rescue efforts, and act as relay devices to transmit emergency information when communication is interrupted, ensuring timely initiation of rescue operations. In short, monitored buoys play a crucial role in shipping monitoring, enhancing shipping safety, efficiency, and emergency response capabilities.

[0004] Monitoring floats will face the following problems in actual use:

[0005] 1. Marine organism attachment: Marine organisms such as barnacles, shellfish, and algae can attach to the surface of the float. Over time, this attachment increases the float's weight, and its varied distribution affects its buoyancy and circumferential stability. Furthermore, the attachment may cover the float's sensors, causing them to lose basic functionality and malfunction.

[0006] 2. Impact of severe weather: In severe weather conditions at sea, strong winds, large waves, heavy rain, hail, and other weather phenomena affect the normal operation of the buoy. In particular, when the buoy is constantly swaying due to the waves, the monitoring equipment it carries may not function properly, its stability is severely compromised, and it lacks self-rescue and self-adjustment capabilities, thus affecting the smooth execution of shipping monitoring tasks. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, a self-stabilizing monitoring float is provided to solve the above problems.

Detailed Implementation

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0026] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8This embodiment describes a self-stabilizing monitoring float comprising a base frame 1, a centrally located self-stabilizing component 2, a camera 3, and multiple propellers 5. The base frame 1 is a circular hollow frame. Multiple propellers 5 are hinged to the bottom of the base frame 1 along its circumference. The centrally located self-stabilizing component 2 is located on the top of the base frame 1, and the camera 3 is detachably connected to the centrally located self-stabilizing component 2. The centrally located self-stabilizing component 2 includes a connecting seat 2-1, a connecting rod 2-2, a counterweight 2-3, an inner ring component 2-4, a middle ring component 2-5, an outer ring component 2-6, two first connecting rods 2-7, and two first bearings. 2-8, two second connecting rods 2-9, two second bearings 2-10, and multiple inclined support rods 2-11; the inner ring 2-4, middle ring 2-5, and outer ring 2-6 are coaxially arranged from the inside to the outside; the connecting rod 2-2 passes through the inner ring 2-4; the upper end of the connecting rod 2-2 is detachably connected to the bottom of the connecting seat 2-1; the camera 3 is installed on the top of the connecting seat 2-1; the camera 3 is detachably connected to the connecting seat 2-1; the lower end of the connecting seat 2-1 is detachably connected to the upper end of the connecting rod 2-2; the lower end of the connecting rod 2-2... A counterweight 2-3 is provided. An inner ring 2-4 is provided on the outer wall of the connecting rod 2-2. The inner ring 2-4 has two inner holes 2-4-1 machined along its thickness direction, and the two inner holes 2-4-1 are coaxially arranged. A second bearing 2-10 is installed in each inner hole 2-4-1. A second connecting rod 2-9 is correspondingly arranged with each second bearing 2-10. One end of each second connecting rod 2-9 passes through its corresponding second bearing 2-10, and the other end of each second connecting rod 2-9 is located on the inner wall of the middle ring 2-5. The middle ring 2-5 extends along its thickness direction... Two external holes 2-5-1 are machined in the degree direction. The two external holes 2-5-1 are coaxially arranged. A first bearing 2-8 is installed in each external hole 2-5-1. The first bearing 2-8 is arranged in a one-to-one correspondence with the first connecting rod 2-7. One end of each first connecting rod 2-7 passes through its corresponding first bearing 2-8. The other end of each first connecting rod 2-7 is set on the inner wall of the outer ring 2-6. Multiple inclined support rods 2-11 are arranged along the circumference of the outer wall of the outer ring 2-6. The lower end of the inclined support rod 2-11 is set on the upper end of the base frame 1.

[0027] The length direction of the first connecting rod 2-7 is horizontal and perpendicular to the length direction of the second connecting rod 2-9. For ease of description, the length direction of the first connecting rod 2-7 is the X-axis and the length direction of the second connecting rod 2-9 is the Y-axis. When the present invention shakes with the swaying of the water surface, under the action of the gravity of the counterweight 2-3, the connecting seat 2-1, the connecting rod 2-2 and the counterweight 2-3 always tend to be close to the vertical horizontal plane, ensuring the stability of the camera 3. At this time, the inner ring 2-4 tilts accordingly with the shaking about the Y-axis, and the middle ring 2-5 tilts accordingly with the shaking about the X-axis. By tilting the inner ring 2-4 and the middle ring 2-5 accordingly with the shaking, the camera 3 only produces slight shaking, thereby achieving the purpose of stable operation of the camera 3.

[0028] Specific Implementation Method 2: This implementation method is a further limitation of Specific Implementation Method 1. The base frame 1 includes an annular cage 1-1, a cage cover 1-2 and a plurality of floats 1-3. The cage cover 1-2 is detachably connected to the annular cage 1-1. The annular cage 1-1 and the cage cover 1-2 enclose an annular cavity 4. The annular cavity 4 has a plurality of floats 1-3 inside it along its circumference.

[0029] When the present invention sways with the fluctuations of the water surface and the base frame 1 tilts to one side, one end sinks and the other end rises. The float 1-3 at the raised end moves along the channel of the annular cavity 4 to the sinking end, thereby increasing the buoyancy of the sinking end and enabling the sinking end to float up, so as to achieve the purpose of the present invention to quickly restore balance.

[0030] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. The outer wall of the connecting rod 2-2 is machined with multiple threaded holes 2-2-1 along its length direction. The inner ring 2-4 is provided with two positioning screws 2-12 along its thickness direction. The two positioning screws 2-12 are coaxially arranged. The positioning screws 2-12 are arranged in a one-to-one correspondence with the threaded holes 2-2-1. The end of the positioning screw 2-12 is threadedly connected to one of the threaded holes 2-2-1.

[0031] Remove the positioning screw 2-12, adjust the positional relationship between the connecting rod 2-2 and the inner ring 2-4 to adjust the height of the counterweight 2-3, and then fix the position of the connecting rod 2-2 with the positioning screw 2-12.

[0032] When the counterweight is at position 2-3, it will enhance the anti-tipping ability to a certain extent. When the counterweight is at position 2-3, it will be more stable in a stationary state and less prone to shaking. The corresponding adjustment can be made according to the actual situation.

[0033] Specific Implementation Method Four: This implementation method further defines Specific Implementation Methods One, Two, or Three. Multiple propellers 5 are arranged circumferentially at the lower end of the cage cover 1-2. Each propeller 5 includes a hinge shaft 5-1 and multiple blades 5-2. The hinge shaft 5-1 is arranged circumferentially with multiple blades 5-2. One end of each blade 5-2 is detachably connected to the circumferential outer wall of the hinge shaft 5-1. The top side of each blade 5-2 is clearance-fitted with the bottom of the cage cover 1-2. The top and bottom sides of each blade 5-2 are both blade edges, and the other end of each blade 5-2 is a blade tip. In this implementation method, the circumferential bottom arrangement of the multiple propellers 5 allows them to rotate with the seawater fluctuations, achieving the function of removing attached materials during rotation.

[0034] In this embodiment, the propeller 5 does not have a separate power source. It only needs the seawater to drive the propeller 5 to rotate when it is flowing. Since the blades 5-2 of the propeller 5 are fitted with the lower end face of the cage 1-2 with a gap, the size of the gap can ensure that the probability of sessile organisms entering is reduced. It ensures that the seawater can smoothly drive the propeller 5 to rotate at the corresponding position when it is flowing, thereby achieving timely and effective cutting performance at the circumferential local position or the overall position. Therefore, when the propeller 5 rotates with the seawater, it scrapes off the organisms attached to the lower end face of the cage 1-2, reducing the probability of marine organism attachment.

[0035] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3 or 4. The upper end of the connecting rod 2-2 is machined with a telescopic cavity 2-2-2 along its length direction. A telescopic rod 6 is inserted into the telescopic cavity 2-2-2. The upper end of the telescopic rod 6 is detachably connected to the connecting seat 2-1. The telescopic rod 6 is machined with multiple threaded holes 6-1 along its length direction. The threaded holes 6-1 are blind holes. An adjusting screw 7 is inserted into the connecting rod 2-2 along its thickness direction. The end of the adjusting screw 7 is threadedly connected to one of the threaded holes 6-1.

[0036] Remove the adjusting screw 7 and move the telescopic rod 6 outward along the length of the telescopic cavity 2-2-2, thereby extending the length of the exposed end of the telescopic rod 6 and increasing the height of the connecting seat 2-1, thus achieving the purpose of adjusting the height of the camera 3.

[0037] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four or Five. The outer surfaces of the annular cage 1-1 and the cage cover 1-2 are provided with an anti-corrosion coating. The anti-corrosion coating can effectively prevent the annular cage 1-1 and the cage cover 1-2 from being eroded by seawater.

[0038] Specific Implementation Method Seven: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four, Five, or Six. Camera 3 is a camera with an existing axisymmetric structure, specifically a dual-head camera. The dual-head camera includes two cameras, which are arranged side by side on the camera base. Each camera structure mainly includes optical components, sensors, processing chips, and circuit systems. One camera is an existing laser night vision camera, and its working principle is the same as that of an existing laser night vision camera. The other camera is an existing low-light night full-color camera, and its working principle is the same as that of an existing low-light night full-color camera. It can provide stable and clear image quality at night, thereby providing favorable conditions for forming stable and effective image data.

[0039] Working principle:

[0040] The present invention is placed in the designated water area according to the predetermined requirements. The base frame 1 provides buoyancy to ensure that the present invention can float on the water. When the present invention shakes with the movement of the water, the circumferential bottom arrangement of the multiple propellers 5 can rotate with the seawater fluctuations, forming a dynamic disturbance structure at multiple positions on the bottom, reducing the probability of marine organism attachment. The middle ring 2-5 tilts accordingly with the first connecting rod 2-7 as the axis, and the inner ring 2-4 tilts accordingly with the second connecting rod 2-9 as the axis, so that the connecting seat 2-1, the connecting rod 2-2 and the counterweight 2-3 are always close to the vertical horizontal plane, thereby ensuring the durability and stability of the camera 3 on the connecting seat 2-1. The camera 3 itself can always be in a relatively stable state on the water surface, which is conducive to obtaining image data with a standard viewing angle.
