Description

Technical Field

[0001] This invention relates to the field of marine environmental monitoring technology, and specifically to a marine noise monitoring device. Background Technology

[0002] Ocean noise, also known as ocean background noise, includes marine environmental noise and technical noise. Marine dynamic noise and biological noise are collectively referred to as marine environmental noise. Generally speaking, marine dynamic noise is generated by waves, ocean currents, and wind, while biological noise is generated by various marine organisms such as fish, shrimp, and mammals. Technical noise is caused by the machinery of ships and the technical equipment in ports. Research on ocean noise is essential for the design and use of underwater acoustic equipment, as well as the improvement of underwater weapons such as mines and torpedoes, and for reducing the noise of ships. Furthermore, in marine ranching—a production sector that utilizes large-scale fisheries facilities and systematic management systems to gather artificially released economically valuable marine organisms, similar to grazing cattle and sheep on land, and for the planned and purposeful release of marine resources such as fish, shrimp, shellfish, and algae—ocean noise detection is also extremely important.

[0003] Existing marine noise monitoring devices mostly employ sound monitoring equipment, typically consisting of only a floating structure and monitoring devices. However, most of these floating structures are relatively simple and are easily affected by air currents when floating in seawater, resulting in large-scale displacement and impacting the stability of the monitoring. Summary of the Invention

[0004] The purpose of this invention is to provide a marine noise monitoring device to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a marine noise monitoring device, comprising a main buoy box, a float cone fixedly connected to the bottom of the main buoy box, both the float cone and the receiving groove being hollow plastic structures to ensure buoyancy in seawater, a lifting rod installed inside the float cone, a probe head fixedly connected to the bottom of the lifting rod, an underwater noise monitoring instrument installed in the probe head, a concave receiving groove provided around the float cone, an outward-folding rod installed in the receiving groove, the end of the outward-folding rod rotatably installed inside the receiving groove, a drive rod rotatably installed on the main buoy box at positions corresponding to the outward-folding rods, a push-pull rod rotatably connected to the end of the drive rod away from the main buoy box, the end of the push-pull rod away from the drive rod rotatably connected to the top of the outward-folding rod, and a fin fixedly connected between the outward-folding rod and the receiving groove. The main buoy is equipped with a drive assembly that drives a drive rod to swing downwards. This drive assembly, through a push-pull rod connection, pushes the outward-opening rods to extend the fins, forming a structure similar to fish fins. When all the outward-opening rods are fully extended, multiple sheet-like structures are formed on the outside of the main buoy and the receiving tank, creating resistance against the seawater. This prevents the device from drifting or rotating when blown by the wind, thus reducing the device's mobility and improving its stability during testing. Driving the drive rod upwards to swing the outward-opening rods allows the fins to be stored in the receiving tank, reducing the resistance between the device and the seawater and facilitating the movement and towing of the device by ships, greatly improving the equipment's practicality.

[0006] Preferably, the drive assembly is a worm gear, with a worm wheel fixedly connected to one end of the drive rod near the main buoy. The number of worm gears corresponds to the number of drive rods. The worm gears are rotatably installed inside the main buoy, and the worm gears mesh with each other. Each worm gear is driven to rotate by a separate drive motor, thereby allowing individual control of each outward-turning rod to improve the actual adaptability of the device.

[0007] Preferably, the monitoring device also includes auxiliary buoy boxes, and multiple auxiliary buoy boxes are configured. The external of each auxiliary buoy box is rotatably connected to a connecting cable. The end of the connecting cable away from the auxiliary buoy box is rotatably connected to the connection point of the push-pull rod and the outward flapping rod. Thus, when the drive rod is clustered and stored, the auxiliary buoy box can be pulled onto the main buoy box for storage. When the drive rod expands and drives the outward flapping rod to open, the auxiliary buoy box can also be pushed into the water. The auxiliary buoy boxes are distributed in a circumferential manner, which can increase the buoyancy of the entire device. In addition, the distribution diameter of the auxiliary buoy boxes is increased, which increases the contact area between the device and the sea surface, making the device float more stably and less prone to swaying from side to side.

[0008] Preferably, a surface noise monitoring instrument is fixedly installed inside the auxiliary buoy. The surface noise monitoring instrument is located on the top of the auxiliary buoy, which can add a noise detection module to the device, so that it can effectively detect surface noise while monitoring underwater noise.

[0009] Preferably, a searchlight is fixedly installed inside the auxiliary buoy, located at the bottom of the auxiliary buoy and pointing downwards. A video acquisition device is fixedly installed on the outer wall of the probe head, recording horizontally. The video acquisition device can be a commonly used camera device and is waterproofed. By illuminating the seawater with the searchlight and cooperating with the video acquisition device, the light intensity and conditions in the water are recorded and identified below the water surface. This allows for the detection of turbidity and floating objects in the seawater, enhancing the detection capabilities of the seawater and further improving the functionality of the device.

[0010] Preferably, the lifting mast is slidably installed inside the float cone. A connecting rod is connected to the top of the lifting mast. The top of the connecting rod passes through the main float box and is connected to a plug. The connecting rod and the lifting mast, as well as the connecting rod and the plug, are threaded together. In use, the plug is located at the top of the main float box to support the lifting mast. The circuit cables of each device in the probe can be led out along the connecting rod. A battery can be installed in the main float box, or a longer cable can be installed to connect it to a power supply location on the ship or shore to power the equipment.

[0011] Preferably, the connecting rod is a multi-section unit rod, and the unit rods are threaded together. This allows for the selection of an appropriate number of connecting rods for combination and connection according to the required monitoring depth, thereby changing the extension depth of the probe and further improving the practicality of the device.

[0012] Preferably, a shielding cloth is provided on the top of the main buoy, and a fixing ring is fixedly connected to the center of the shielding cloth. A connecting rod passes through the fixing ring, and a plug is located above the fixing ring. The plug is fixed to the main buoy by pulling down the probe. The outer periphery of the shielding cloth is fixedly connected to the push-pull rod. Thus, by opening the drive rod, the shielding cloth can be unfolded over a large area to form a large shielding cloth to protect the device, further improving the safety of the device.

[0013] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0014] 1. This invention, by combining a main buoy and a float cone, makes the device more stable when floating in seawater. The float cone increases buoyancy, and by driving the drive rod to swing downward, it pushes the outward-opening rod to extend the fins, forming a structure similar to fish fins. This creates resistance with the seawater, making it less prone to drifting or rotating when blown by the wind, thus reducing the device's mobility and improving its stability during detection. Driving the drive rod to swing upward collects the outward-opening rod, or alternatively, the fins can be stored in the receiving groove, reducing the resistance between the device and the seawater, making it easier for ships to move and tow the device, greatly improving the practicality of the equipment.

[0015] 2. This invention adds an auxiliary buoy to the connection point of the drive rod and the push-pull rod. When the drive rod expands, it pushes the auxiliary buoy into the water. The auxiliary buoys are distributed in a circular pattern, which increases the buoyancy of the entire device. The increased distribution diameter of the auxiliary buoys makes the device float more stably and less prone to swaying. At the same time, the device can also add a water noise detection module. By using a searchlight to illuminate the seawater and cooperating with a video acquisition device to record and identify the light intensity and conditions in the water below the surface, the device can detect the turbidity and floating objects in the seawater, enhancing the detection capabilities of the seawater and further improving the functionality of the device.

[0016] 3. This invention connects the lifting rod to the main float box via a connecting rod and fixes it with a plug. The appropriate number of connecting rods can be combined to change the depth of the probe, thus improving the device's practicality. Furthermore, a shielding cloth is placed on top of the main float box. When the drive rod opens, the shielding cloth can be fully extended to form a large shielding cloth to protect the device, further enhancing its safety. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] This invention provides, for example Figure 1-2 The illustrated marine noise monitoring device includes a main buoy 1, with a float cone 11 fixedly connected to the bottom of the main buoy 1. Both the float cone 11 and the receiving groove 12 are hollow plastic structures to ensure buoyancy in seawater. A lifting rod 2 is installed inside the float cone 11, and a probe 3 is fixedly connected to the bottom of the lifting rod 2. An underwater noise monitoring instrument 31 is installed in the probe 3. A concave receiving groove 12 is provided around the float cone 11, and an outward-folding rod 4 is installed in the receiving groove 12. The end of the outward-folding rod 4 is rotatably installed inside the receiving groove 12. A drive rod 5 is rotatably installed on the main buoy 1 at a position corresponding to the outward-folding rod 4. A push-pull rod 6 is rotatably connected to the end of the drive rod 5 away from the main buoy 1, and the end of the push-pull rod 6 away from the drive rod 5 is rotatably connected to the top of the outward-folding rod 4. The outward-folding rod 4 is fixedly connected to the receiving groove 12. The fin cloth 41 is provided on the main float box 1, which is equipped with a drive assembly that drives the drive rod 5 to swing downward. This drive assembly drives the drive rod 5 to swing downward, and through the connection of the push-pull rod 6, pushes the outward-opening rod 4 to open outward, and pulls out the fin cloth 41 to form a structure similar to a fish fin. That is, when all the outward-opening rods 4 are fully open, multiple sheet-like structures will be formed on the outside of the main float box 1 and the receiving tank 12, which will create resistance with the seawater. Therefore, when blown by the wind, it is not easy to drift around or rotate, thereby reducing the mobility of the device and improving the stability of the device during detection. Driving the drive rod 5 to swing upward can collect the outward-opening rods 4 and store the fin cloth 41 in the receiving tank 12, reducing the resistance between the device and the seawater, so as to facilitate the movement and towing of the device by ships, which greatly improves the practicality of the equipment.

[0029] Furthermore, in the above technical solutions, such as Figure 4As shown, the drive assembly is a worm gear 13. A worm wheel 51 is fixedly connected to one end of the drive rod 5 near the main float box 1. The number of worm gears 13 corresponds to the number of drive rods 5. The worm gears 13 are rotatably installed inside the main float box 1, and the worm gears 13 and worm wheels 51 mesh with each other. Each worm gear 13 is driven to rotate by a separate drive motor 14, so that each outward turning rod 4 can be individually controlled to improve the actual adaptability of the device.

[0030] Working Principle: By combining the main buoy 1 and the float cone 11, the device becomes more stable when floating in seawater. The float cone 11 increases buoyancy, stabilizing the center of gravity of the drooping probe 3, making the overall equipment more stable. Multiple sets of outward-folding rods 4 are installed on the float cone 11. In actual use, the drive rod 5 can be driven downward to open the outward-folding rods 4, pulling out the fin cloth 41 to form a structure similar to a fish fin. When all the outward-folding rods 4 are fully open, multiple sheet-like structures are formed on the outside of the main buoy 1 and the receiving trough 12, creating resistance with the seawater. This prevents the device from drifting or rotating when blown by the wind, reducing its mobility and improving its stability during detection. Alternatively, the drive rod 5 can be driven upward to collect the outward-folding rods 4, or the fin cloth 41 can be stored in the receiving trough 12, reducing the resistance between the device and the seawater, facilitating movement and towing by ships, greatly improving the practicality of the equipment.

[0031] Example 2

[0032] Based on Embodiment 1, a marine noise monitoring device, such as Figures 1 to 3 As shown, it also includes auxiliary buoy boxes 7, of which multiple auxiliary buoy boxes 7 are configured. The external of the auxiliary buoy box 7 is rotatably connected to a connecting cable 71. The end of the connecting cable 71 away from the auxiliary buoy box 7 is rotatably connected to the connection point of the push-pull rod 6 and the outward flapping rod 4. Thus, when the drive rod 5 is clustered and stored, the auxiliary buoy box 7 can be pulled onto the main buoy box 1 for storage. When the drive rod 5 is spread out, causing the outward flapping rod 4 to open, the auxiliary buoy box 7 can also be pushed into the water. The auxiliary buoy boxes 7 are distributed in a circular pattern, which can increase the buoyancy of the entire device. In addition, the distribution diameter of the auxiliary buoy boxes 7 is increased, which increases the contact area between the device and the sea surface, making the device float more stably and less prone to swaying from side to side.

[0033] Furthermore, in the above technical solutions, such as Figure 2 and Figure 6 As shown, a surface noise monitor 72 is fixedly installed inside the auxiliary buoy 7. The surface noise monitor 72 is located on the top of the auxiliary buoy 7, which can add a noise detection module to the device, so that it can effectively detect surface noise while monitoring underwater noise.

[0034] Furthermore, in the above technical solutions, such as Figure 2 and Figure 6 As shown, a searchlight 73 is fixedly installed inside the auxiliary buoy 7. The searchlight 73 is located at the bottom of the auxiliary buoy 7 and shines downwards. A video acquisition device 32 is fixedly installed on the outer wall of the probe head 3. The video acquisition device 32 records horizontally. The video acquisition device 32 can be a commonly used camera device and is waterproofed. The searchlight 73 illuminates the seawater, and the video acquisition device 32 records and identifies the light intensity and conditions in the water below the surface. This allows for the detection of turbidity and floating objects in the seawater, enhancing the detection capabilities of the seawater and further improving the functionality of the device.

[0035] Working principle: By connecting and installing an auxiliary buoy 7 at the connection point of the drive rod 5 and the push-pull rod 6, and installing a water noise monitoring instrument 72 and a searchlight 73 in the auxiliary buoy 7, the auxiliary buoy 7 can be pulled onto the main buoy 1 for storage when the drive rod 5 is clustered and stored. When the drive rod 5 expands and drives the outward flapping rod 4 to open, the auxiliary buoy 7 can also be pushed into the water. The auxiliary buoy 7 is distributed in a circular pattern, which can increase the buoyancy of the entire device. The increased distribution diameter of the auxiliary buoy 7 increases the contact area between the device and the sea surface, making the device float more stably and less prone to swaying. At the same time, a noise detection module is added to the device, which can effectively detect surface noise while monitoring underwater noise. The searchlight 73 illuminates the seawater, and the video acquisition device 32 records and identifies the light intensity and conditions in the water below the surface, thereby detecting the turbidity and floating objects in the seawater, enhancing the detection of seawater and further improving the functionality of the device.

[0036] Example 3

[0037] Based on the marine noise monitoring device of Embodiment 2, further, in the above technical solution, such as Figures 1 to 3 As shown, the lifting rod 2 is slidably installed inside the float cone 11. The top of the lifting rod 2 is connected to a connecting rod 21, the top of the connecting rod 21 passes through the main float box 1, and is connected to a plug 22. The connecting rod 21 and the lifting rod 2, as well as the connecting rod 21 and the plug 22, are all threadedly connected. In use, the plug 22 is located at the top of the main float box 1 to support the lifting rod 2. The circuit cables of each device in the probe head 3 can be led out along the connecting rod 21. A battery can be installed in the main float box 1, or a longer cable can be installed to connect it to a power supply site on the ship or shore to power the equipment.

[0038] Furthermore, in the above technical solution, the connecting rod 21 is a multi-section unit rod, and the unit rods are threaded together. Thus, according to the required monitoring depth, an appropriate number of connecting rods 21 can be selected for combination and connection, which can change the downward extension depth of the probe head 3 and further improve the practicality of the device.

[0039] Furthermore, in the above technical solutions, such as Figure 3 and Figure 4 As shown, a shielding cloth 8 is provided on the top of the main float box 1. A fixing ring 81 is fixedly connected to the center of the shielding cloth 8. A connecting rod 21 passes through the fixing ring 81. A plug 22 is located above the fixing ring 81. By pulling down the probe head 3, the plug 22 fixes the fixing ring 81 to the main float box 1. The outer periphery of the shielding cloth 8 is fixedly connected to the push-pull rod 6. Thus, by opening the drive rod 5, the shielding cloth 8 can be unfolded over a large area to form a large shielding cloth to shield and protect the device, further improving the safety of the device.

[0040] Working principle: The lifting rod 2 is connected to the connecting rod 21 and passes through the main float box 1. It is fixed by the plug 22. Then, according to the required monitoring depth, the appropriate number of connecting rods 21 can be selected for combination connection, which can change the extension depth of the probe 3, further improving the practicality of the device. In addition, a shielding cloth 8 is set on the top of the main float box 1. When the drive rod 5 is opened, the shielding cloth 8 can be unfolded over a large range to form a large shielding cloth to protect the device, further improving the safety of the device.

[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
