Description

Technical Field

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

[0002] The development of the marine ecological environment is related to human survival. Therefore, paying attention to the marine environment is also one of our actions to practice environmental protection. In addition to plastic waste, the destruction of the marine ecosystem also includes noise pollution. Usually, marine noise is generated by waves, ocean currents and wind, as well as by various marine organisms such as fish, shrimp and mammals. With the rapid development of the social economy and the shortage of land resources, the number of underwater projects is increasing, such as cross-sea bridges, undersea tunnels and offshore oil and gas extraction platforms. Underwater engineering operations involve underwater blasting, pile driving, drilling and dredging, which will cause serious noise pollution.

[0003] Buoys are important technical equipment for acquiring information on marine environmental noise. At the same time, buoy platforms can carry or mount a variety of sensor modules and underwater detection equipment to measure various parameters continuously, at fixed points and at multiple depths over a long period of time. Therefore, buoys have been widely used in many fields of marine scientific research.

[0004] Marine noise monitoring equipment is not very resistant to waves. Currently, most of the methods used to improve this are to lower the center of gravity, that is, to lower the center of gravity when the waves are large and to raise the center of gravity when the waves are small. This method is not only structurally complex, but also impractical. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a floating marine noise monitoring device that can have strong wave resistance without lowering the center of gravity of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A floating marine noise monitoring device includes a buoy and a connecting rod installed at the bottom of the buoy. The bottom end of the connecting rod is provided with a housing 1 and a housing 2 that are installed on each other. Multiple turntables are rotatably connected to the side wall of the housing 2 in the circumferential direction. Mounting plates are installed on the turntables, and hydrophone arrays are installed on the turntables.

[0008] It also includes a drive mechanism, which drives multiple turntables to rotate, thereby changing the angle at which seawater impacts the mounting plate.

[0009] Preferably, the rotation angle of the turntable is within the range of 0-80°.

[0010] Preferably, the drive mechanism includes a main shaft located in the middle of the housing and a power component for driving the main shaft to move along the axis of the housing. Each turntable is fixedly connected to an eccentric shaft at one end of the inner side of the housing. Each turntable is provided with a connecting arm, and the two ends of the connecting arm are respectively hinged to the end of the eccentric shaft and the outer side of the main shaft.

[0011] Preferably, the axis of the spindle is located on the center plane of the connecting arm.

[0012] Preferably, the power assembly includes an electric telescopic rod and a lever fixedly installed at the output end of the electric telescopic rod. An annular groove is provided on the outer side of the main shaft, and the lever is inserted into the annular groove.

[0013] Preferably, the drive mechanism further includes a stabilizing shaft that is fixedly mounted on the end wall of the housing and movably inserted into the inner side of the spindle end.

[0014] Preferably, it also includes a power generation device, which includes a generator and an output shaft mounted on the generator shaft. The output shaft is inserted inside the end of the main shaft and can move along the main shaft axis. When the main shaft rotates, it can drive the output shaft to rotate. The ends of housing one and housing two are sleeved on each other and housing two can rotate relative to housing one. The bottom end of the connecting rod is fixedly connected to housing one.

[0015] Preferably, the buoy is equipped with an attitude adjustment motor, which drives the housing to rotate around the connecting rod via a drive link, and the axis of the connecting rod is perpendicular to the axis of the housing.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. By setting the mounting plate to be rotatable and adjustable, and by setting multiple mounting plates, the range of noise monitoring can be expanded. On the other hand, by adjusting the angle of the mounting plate, the contact surface of the mounting plate with the waves can be reduced, and the impact angle can be reduced, thereby making the equipment more stable. There is no need to lower the center of gravity. Compared with the method of lowering the center of gravity, the stability is improved by a factor of two.

[0018] 2. When the waves impact the mounting plate, they can cause the housing and the main shaft to rotate. The power of the main shaft is output to the output shaft, which then transmits the power to the generator, thus generating electricity. A battery is installed inside the buoy to store electrical energy and supply power to the devices inside the equipment that require electricity, in order to prevent the equipment from losing power and becoming disconnected.

[0019] 3. By adjusting the orientation of the second shell by the attitude adjustment motor, when the waves are large, the front end of the second shell is oriented towards the direction of the seawater flow. Compared with the side facing the direction of the seawater flow, the impact force is smaller, thereby further improving stability. In addition, when generating electricity, the front end of the second shell can also be oriented towards the waves, at which time the power generation efficiency is higher.

[0029] Example

[0030] like Figures 1 to 5As shown, this embodiment provides a floating marine noise monitoring device, including a buoy 1 and a connecting rod 2 installed at the bottom of the buoy 1. The bottom end of the connecting rod 2 is provided with a housing 3 and a housing 4 that are installed on each other. Multiple turntables 5 are rotatably connected to the side wall of the housing 4 in the circumferential direction. A mounting plate 51 is installed on each turntable 5, and a hydrophone array 52 is installed on each turntable 5. Figure 1 and Figure 2 As shown, there are four turntables 5 and four mounting plates 51, which are evenly distributed on the outside of the housing 4.

[0031] It also includes a drive mechanism 6, which drives multiple turntables 5 to rotate, thereby changing the angle at which seawater impacts the mounting plate 51 when it flows.

[0032] Furthermore, the rotation angle of turntable 5 is within the range of 0-80°.

[0033] like Figure 1 The diagram shows the state during use. The mounting plate 51 is unfolded towards the front end of the housing 4, and the hydrophone array 52 monitors ocean noise. This configuration is suitable for situations with relatively small waves. Depending on the wave size, the drive mechanism 6 rotates the turntable 5 and the mounting plate 51, thereby changing the angle at which the seawater impacts the mounting plate 51. Figure 2 As shown, this is the state when the mounting plate 51 is subjected to large waves. In this state, the waves impact the rear end of the housing 4 from the front end. At this time, the contact area between the waves and the surface of the mounting plate 51 is small, the impact angle is small, and the flow direction is almost parallel to the surface of the mounting plate 51, thereby reducing the impact and improving the stability of the equipment. If the waves impact the equipment from other directions, the impact force can also be reduced by appropriately adjusting the angle of the mounting plate 51.

[0034] In other words, by setting the mounting plate 51 to be rotatable and adjustable, and by setting multiple mounting plates 51, the range of noise monitoring can be expanded. On the other hand, by adjusting the angle of the mounting plate 51, the contact surface of the mounting plate 51 with the waves can be reduced, and the impact angle can be reduced, thereby making the equipment more stable. There is no need to lower the center of gravity. Compared with the method of lowering the center of gravity, the stability is improved many times over.

[0035] In this embodiment, as Figures 3-5 As shown, the drive mechanism 6 includes a main shaft 61 located in the middle of the housing 2 4 and a power assembly 64 for driving the main shaft 61 to move along the axis of the housing 2 4. Each turntable 5 is fixedly connected to an eccentric shaft 62 at one end of the inner side of the housing 2 4. Each turntable 5 is provided with a corresponding connecting arm 63. The two ends of the connecting arm 63 are respectively hinged to the end of the eccentric shaft 62 and the outer side of the main shaft 61.

[0036] Furthermore, the axis of the main shaft 61 is located on the center plane of the connecting arm 63.

[0037] The power assembly 64 can drive the main shaft 61 to move along the axis of the housing 2 4. Since the eccentric shaft 62 is located at the edge of the end, the main shaft 61 can drive the turntable 5 to rotate through the connecting arm 63 and the eccentric shaft 62, thereby causing the mounting plate 51 to rotate to achieve the purpose of adjusting the angle.

[0038] Furthermore, the power assembly 64 includes an electric telescopic rod 642 and a lever 641 fixedly installed at the output end of the electric telescopic rod 642. An annular groove 611 is provided on the outer side of the main shaft 61, and the lever 641 is inserted into the annular groove 611. That is, the electric telescopic rod 642 drives the main shaft 61 to move via the lever 641. The upper end of the lever 641 is U-shaped and inserted into the annular groove 611. The rotation of the main shaft 61 will not affect the installation and fit between the lever 641 and the annular groove 611.

[0039] Furthermore, the drive mechanism 6 also includes a stabilizing shaft 65, which is fixedly mounted on the end wall of the housing 4 and movably inserted into the inner side of the end of the main shaft 61. Figure 5 As shown, the spindle 61 has a certain length. The stabilizing shaft 65 can support the spindle 61, thereby improving the stability of the spindle 61.

[0040] In this embodiment, as Figures 3-5 As shown, a power generation device 7 is also provided. The power generation device 7 includes a generator 71 and an output shaft 72 mounted on the rotating shaft of the generator 71. The output shaft 72 is inserted into the inner side of the end of the main shaft 61 and can move axially along the main shaft 61. When the main shaft 61 rotates, it can drive the output shaft 72 to rotate. The ends of housing 1 3 and housing 2 4 are sleeved together, and housing 2 4 can rotate relative to housing 1 3. The bottom end of the connecting rod 2 is fixedly connected to housing 1 3. The generator 71 and the electric telescopic rod 642 are fixedly installed inside housing 1 3. A spline groove is opened at the end of the main shaft 61. The output shaft 72 is a spline shaft. The spline shaft and the spline groove are matched, and the two can move relative to each other.

[0041] By installing the power generation device 7, power generation can be achieved to prevent equipment from losing power and becoming disconnected. Specifically, during power generation, in... Figure 1 In this state, the mounting plate 51 is rotated by an angle, such as 20°. The waves impact the mounting plate 51, which causes the housing 2 4 to rotate relative to the housing 1 3, that is, the main shaft 61 rotates. The power of the main shaft 61 is output to the output shaft 72, and the output shaft 72 transmits the power to the generator 71, thereby generating electricity. A battery is installed inside the buoy 1 to store electrical energy and supply power to the devices inside the equipment that require electricity.

[0042] In addition, a braking device can be installed inside the housing 4 for braking the spindle 61. When it is necessary to adjust the angle of the mounting plate 51 or to generate electricity, the braking of the spindle 61 can be released. When it is not necessary to adjust the angle or generate electricity, the spindle 61 can be braked. The braking device can be achieved by using friction pads to hold the spindle 61.

[0043] In this embodiment, the buoy 1 is equipped with an attitude adjustment motor, which drives the housing 3 to rotate around the connecting rod 2 via the driving link 2. The axis of the connecting rod 2 is perpendicular to the axis of the housing 3.

[0044] The attitude adjustment motor drives the connecting rod 2 to rotate the housing 3 and the housing 4 together, thereby adjusting the direction of the housing 4. When the waves are large, the front end of the housing 4 faces the direction of the seawater flow, which reduces the impact force compared to facing the side of the seawater flow, thus further improving stability. In addition, when generating electricity, the front end of the housing 4 can also face the waves, which results in higher power generation efficiency.

[0045] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
