AI Technical Summary
When existing shipborne multibeam detection devices operate in nearshore waters, they suffer from poor stability due to the shallow water depth, large topographical variations, and complex hydrodynamic environment of coastal zones, islands, and reefs. This results in unstable attitude of the multibeam transducers, making it difficult to conduct large-scale measurements.
A damping stabilization device is adopted, including a housing, a sliding shaft, and a damping assembly. Flexible belts and elastic buffers are used to absorb the kinetic energy of the hull's swaying. The relative position of the sliding shaft and the housing is changed through guide wheels and sliding grooves to maintain the stable attitude of the multi-beam detection device.
This improves the installation stability and operational reliability of the multibeam detector, ensures measurement accuracy, and meets the near-shore measurement needs in complex hydrodynamic environments.

Abstract
Description
Technical Field
[0001] This application relates to the field of underwater measurement device technology, and in particular to a damping stabilization device and a multi-beam detection device mounting platform. Background Technology
[0002] Multibeam echo sounders are the mainstream equipment for water depth measurement, characterized by high measurement accuracy, large measurement area, fast measurement speed, and real-time three-dimensional high-density water depth point output. They are widely used in seabed topography and geomorphology surveying. Currently, the integrated planning, management, and protection of coastal zones (islands and reefs) requires increasingly robust underground topographic information. However, water depth measurement technology faces bottlenecks due to the influence of sea conditions, topography, and environment in coastal zones (islands and reefs). For example, UAV mapping can only be conducted at low tide in the intertidal zone, requiring specific working windows and limiting large-area mapping capabilities; airborne LiDAR measurement has high requirements for water quality and depth, and laser point clouds are difficult to penetrate in turbid nearshore waters; GNSS real-time dynamic differential positioning (RTK) and post-processing differential positioning (GNSS PPK) require on-site personnel, resulting in low measurement efficiency, high labor intensity, and inability to operate in water depths exceeding 1 meter.
[0003] In related technologies, shipborne multibeam echo sounders can be used for water depth measurement. Multibeam transducers are typically vertically fixed, with the probe emitting downwards. To adapt to the unfavorable factors caused by the shallow waters, varied topography, and complex hydrodynamic environment of nearshore waters such as coastal zones and island reefs, vessels carrying multibeam echo sounders can be small and highly maneuverable, such as small boats or small-tonnage vessels. However, such vessels are prone to instability; the hull rolls significantly due to the seawater, leading to instability in the underwater multibeam transducer's attitude, making it difficult to conduct large-scale measurements in the complex hydrodynamic environment of nearshore areas.

When the sliding shaft moves relative to the housing along its own axial direction, it can drive the first elastic buffer to stretch or change the position of the guide wheels in the flexible belt.
[0006] In some embodiments of this application, the damping component further includes a bracket, the bracket including a top wall, a bottom wall and a side wall, the housing having a top cover and a bottom cover along its own axial direction, the top wall being fixedly connected to the top cover, the bottom wall being fixedly connected to the bottom cover, and the two ends of the flexible strip being fixed to the top wall and the bottom wall respectively;
[0007] The sidewall is connected to the top wall and the sidewall. The sidewall is provided with a first sliding groove, which extends along the axial direction of the housing. The shaft of the guide wheel is slidably connected in the first sliding groove.
[0008] In some embodiments of this application, the damping assembly further includes a fixed steering wheel and a sliding steering wheel. The fixed steering wheel is fixedly disposed on one of the top wall or the bottom wall, and the sliding steering wheel is movably disposed on the other of the top wall or the bottom wall. The first elastic buffer is connected to the sliding steering wheel, and the flexible belt is connected to the first elastic buffer through the sliding steering wheel. The flexible belt is sequentially wound around one of the guide wheels, the fixed steering wheel, the sliding steering wheel, and the other guide wheel.
[0009] In some embodiments of this application, the bottom wall of the bracket is spaced apart from the bottom cover of the housing and forms an installation space, the first elastic buffer is housed in the installation space, one end of the first elastic buffer is fixedly connected to the bottom cover, and the other end is connected to the sliding steering wheel.
[0010] In some embodiments of this application, a second sliding groove is further provided on the side wall, the second sliding groove is arranged parallel to the first sliding groove, and the shaft of the sliding steering wheel is slidably connected in the second sliding groove.
[0011] In some embodiments of this application, the damping assembly is provided in multiple sets, and the multiple sets of damping assemblies are arranged at equal intervals along the circumference of the housing.
[0012] In some embodiments of this application, the sliding shaft includes a shaft and a mounting ring. The first end of the shaft passes through the housing, and the mounting ring is sleeved on the outer periphery of the first end of the shaft. The mounting ring has multiple supports protruding radially, and each support is correspondingly arranged with multiple sets of damping components. Two guide wheels in each set of damping components are rotatably mounted on the support. The mounting ring has a receiving cavity, and a second elastic buffer is provided in the receiving cavity.
[0013] In some embodiments of this application, the slide shaft is provided with a cable groove for the cable to pass through, and the cable groove, the slide shaft and the housing are coaxially arranged.
[0014] In some embodiments of this application, the damping stabilizing device is further provided with a conduit, one end of which is connected to the cable groove and the other end is connected to the bottom cover of the housing and connected to the outside of the housing through the bottom cover. The sliding shaft is slidable relative to the conduit. The conduit is used to connect the cable to the outside of the bottom cover. The outside of the bottom cover is used to install a multi-beam detection device.
[0015] Secondly, this application also provides a multi-beam detection device mounting platform, including a connecting component and the damping stabilizing device provided in the first aspect.

The connecting component and the damping stabilizing device are detachably connected.
[0016] The embodiments of this application have at least the following beneficial effects: When the work vessel operates in water, it is impacted by the water flow, resulting in hull swaying. This swaying is transmitted to the damping stabilization device via a sliding shaft, causing relative movement between the sliding shaft and the housing. Since the flexible belt is wrapped around the outer periphery of the first elastic buffer and the two guide wheels, and both ends of the flexible belt are fixed to the inner walls at both ends of the housing, the total length of the flexible belt is constant. Due to the hull swaying, the sliding shaft can move relative to the housing along its own axis, thereby causing the guide wheels to slide within the flexible belt and change their position. Therefore, by utilizing the buffering effect of the damping component, the kinetic energy of the sliding shaft can be absorbed and converted into a change in the relative position between the sliding shaft and the housing, thus keeping the housing essentially stationary. In this situation, the multi-beam detector mounted on the housing can obtain a stable operating environment, ensuring that the multi-beam detector maintains a good posture during operation, thereby improving the reliability and accuracy of the multi-beam detector operation.

[0034] Firstly, please refer to Figure 1This application provides a multi-beam detection device mounting platform 200, including a connecting assembly 210 and a damping stabilizing device 100. One end of the connecting assembly 210 is fixedly connected to the ship's side 400, and the other end is connected to the damping stabilizing device 100. The connecting assembly 210 and the damping stabilizing device 100 are detachably connected. Using the connecting assembly 210, the damping stabilizing device 100 can be connected to the ship's side 400, and the multi-beam detection device 300 is mounted on the housing 10 of the damping stabilizing device. Therefore, the connection between the multi-beam detection device 300 and the working vessel is realized. The water flow impact experienced by the working vessel in the water is transmitted to the damping stabilizing device 100 through the connecting assembly 210. The damping stabilizing device 100 absorbs the vibration, thereby providing a stable installation environment for the multi-beam detection device 300 and providing conditions for its smooth operation. The damping stabilizing device 100 is detachably connected to the connecting component 210. This allows for flexible selection of different specifications of the connecting component 210 based on various factors such as the height of the work vessel and the target depth of the work position, thus enabling the damping stabilizing device 100 to be installed adaptably.
[0035] The specific structure of the damping stabilizing device 100 will be further described below.
[0036] Please see Figures 2 to 4 The first aspect of this application provides a damping stabilization device 100. A multi-beam detector 300 can be installed on the hull 400 of a work vessel through the damping stabilization device 100. By navigating the work vessel to the target area, the multi-beam detector 300 can carry out measurement operations in the corresponding water area. The damping stabilization device 100 can achieve stable installation of the multi-beam detector 300 and improve the stability of the multi-beam detector 300 during operation.
[0037] The damping stabilization device 100 includes a housing 10, a sliding shaft 20, and a damping assembly 30. The outer periphery of the housing 10 is used to mount a multi-beam detector 300. The first end of the sliding shaft 20 passes through the housing 10, and the second end of the sliding shaft 20 is used to connect to the ship's side 400. The damping assembly 30 is disposed in the housing 10 and includes a flexible belt 31, a first elastic buffer 32, and at least two guide wheels 33. The two guide wheels 33 are disposed at the first end of the sliding shaft 20. The first elastic buffer 32 is disposed on the inner wall of one end of the housing 10. One end of the flexible belt 31 is fixed to the inner wall of one end of the housing 10, and the flexible belt 31 is wrapped around the outer periphery of the first elastic buffer 32 and the two guide wheels 33. The other end of the flexible belt 31 is fixed to the inner wall of the other end of the housing 10. The total length of the flexible belt is constant. When the sliding shaft 20 moves relative to the housing 10 along its own axial direction, it can drive the first elastic buffer 32 to stretch or change the position of the guide wheels 33 in the flexible belt 31.
[0038] When the work vessel operates in the water, it is impacted by the water flow, resulting in hull swaying. This swaying is transmitted to the damping stabilizing device 100 via the sliding shaft 20, causing relative movement between the sliding shaft 20 and the housing 10. Since the flexible belt 31 is wrapped around the outer periphery of the first elastic buffer 32 and the two guide wheels 33, and both ends of the flexible belt 31 are fixed to the inner walls at both ends of the housing 10, the total length of the flexible belt 31 is constant. Due to the swaying of the hull, the sliding shaft 20 can move relative to the housing 10 along its own axis, thereby causing the guide wheels 33 to slide within the flexible belt 31, changing their position within the flexible belt 31. Therefore, by utilizing the buffering effect of the damping component 30, the kinetic energy of the sliding shaft 20 can be absorbed and converted into a change in the relative position between the sliding shaft 20 and the housing 10, thereby keeping the housing 10 basically stationary. At this time, the multi-beam detection device 300 installed on the housing 10 can obtain a stable operating environment, ensuring that the multi-beam detection device 300 can maintain a good posture during operation, thereby improving the reliability and accuracy of the multi-beam detection device 300 operation.
[0039] Furthermore, the impact of water flow on the damping stabilization device 100 can manifest as either violent shaking or slight, slow shaking. The first elastic buffer 32 can exhibit different functions in these two different situations. Specifically, when the sliding shaft 20 is subjected to a large instantaneous impact force, the guide wheel 33 causes the flexible belt 31 to tighten, pulling the first elastic buffer 32 to undergo tensile deformation. Thus, the large kinetic energy transmitted from the sliding shaft 20 is converted into the deformation potential energy of the first elastic buffer 32. When the kinetic energy of the sliding shaft 20 disappears, the first elastic buffer 32 gradually returns to its original position. In this way, the large impact force of the sliding shaft 20 can be simultaneously converted into the deformation of the first elastic buffer 32 and a change in the relative position between the sliding shaft 20 and the housing 10, keeping the housing 10 generally stable. When the sliding shaft 20 is subjected to a slow and smooth force, such as a slight vibration of the hull, the acceleration of the sliding shaft 20 is small. Therefore, the tension of the flexible belt 31 on the first elastic buffer 32 is small, and the first elastic buffer 32 hardly deforms. The slight impact is eliminated by the relative sliding between the sliding shaft 20 and the shell 10.
[0040] For example, the flexible belt 31 can be a rope, chain or other structure, and the first elastic buffer 32 can be a tension spring or other structure.
[0041] In some embodiments, the damping assembly 30 further includes a bracket 34, which includes a top wall 341, a bottom wall 342, and a side wall 343. The housing 10 is provided with a top cover 11 and a bottom cover 12 along its own axial direction. The top wall 341 is fixedly connected to the top cover 11, and the bottom wall 342 is fixedly connected to the bottom cover 12. The two ends of the flexible belt 31 are respectively fixed to the top wall 341 and the bottom wall 342. The side wall 343 is connected to the top wall 341 and the side wall 343. The side wall 343 is provided with a first sliding groove 3431, which extends along the axial direction of the housing 10. The rotating shaft of the guide wheel 33 is slidably connected in the first sliding groove 3431. The top wall 341, bottom wall 342, and side wall 343 can be mutually enclosed to form a certain space, thereby housing the flexible belt 31, the first elastic buffer 32, and other structures within this space. On the one hand, this ensures that the damping assembly 30 provides an independent environment for the guide wheel 33, flexible belt 31, etc., during use, preventing them from becoming entangled or interfering with other structures within the housing 10, thus improving the independence and reliability of the damping assembly 30. On the other hand, this allows the damping assembly 30 to form an independent structure, facilitating its initial installation before being fully integrated into the housing 10. The first sliding groove 3431 provides guidance for the sliding of the guide wheel 33, making its sliding smoother and more stable.
[0042] In some embodiments, the damping assembly 30 further includes a fixed steering wheel 35 and a sliding steering wheel 36. The fixed steering wheel 35 is fixedly mounted on one of the top wall 341 or the bottom wall 342, while the sliding steering wheel 36 is movably mounted on the other. A first elastic buffer 32 is connected to the sliding steering wheel 36. A flexible belt 31 is connected to the first elastic buffer 32 via the sliding steering wheel 36. The flexible belt is sequentially wound around one guide wheel 33, the fixed steering wheel 35, the sliding steering wheel 36, and the other guide wheel 33. By providing the fixed steering wheel 35 and the sliding steering wheel 36, the flexible belt 31 can be wound around it and its direction can be achieved. The rolling action of the steering wheels helps reduce the friction and resistance of the flexible belt 31, improving its smoothness. When the tension of the flexible belt 31 is small, the first buffer elastic member hardly deforms, and the position of the sliding steering wheel 36 hardly changes; that is, the sliding steering wheel 36 acts as a fixed pulley. When the tension of the flexible belt 31 is large, the first buffer elastic element will be stretched and deformed. At this time, the sliding steering wheel 36 will act as a movable pulley.
[0043] As an alternative implementation, the fixed steering wheel 35 can also be replaced by a hook, pull ring, or other structure, with the flexible belt 31 threaded through the hook or pull ring to achieve the steering function of the flexible belt 31. In an implementation without the sliding steering wheel 36, the flexible belt 31 can also be directly slidably threaded through the first elastic buffer 32, for example, the flexible belt 31 can be threaded through a spring, and the spring can undergo tensile deformation under the tension of the flexible belt 31.
[0044] In some embodiments, the bottom wall 342 of the bracket 34 is spaced apart from the bottom cover 12 of the housing 10, forming an installation space 13. The first elastic buffer 32 is housed in the installation space 13, with one end of the first elastic buffer 32 fixedly connected to the bottom cover 12 and the other end connected to the sliding steering wheel 36. By providing the installation space 13, the first elastic buffer 32 can be housed therein, and sufficient space is provided for the deformation and repositioning of the first elastic buffer 32.
[0045] In some embodiments, a second sliding groove 3432 is further provided on the side wall. The second sliding groove 3432 is arranged parallel to the first sliding groove 3431, and the shaft of the sliding steering wheel 36 is slidably connected in the second sliding groove 3432. The second sliding groove 3432 can provide guidance for the movement of the sliding steering wheel 36, thereby improving the sliding stability and smoothness of the sliding steering wheel 36.
[0046] In some embodiments, please refer to Figure 5 Multiple sets of damping components 30 are provided, and these sets of damping components 30 are equally spaced along the circumference of the housing 10. Providing multiple sets of damping components 30 can offer multiple buffers against the impact of the sliding shaft 20, further improving the buffering and stabilizing effect of the damping stabilizing device 100. The equal spacing of the damping components 30 along the circumference of the housing 10 can improve the force balance of the sliding shaft 20 relative to the housing 10 during movement, further improving the smoothness of the sliding of the sliding shaft 20.
[0047] In some embodiments, please refer to Figure 6 The sliding shaft 20 includes a shaft 21 and a mounting ring 22. The first end of the shaft 21 passes through the housing 10, and the mounting ring 22 is sleeved on the outer periphery of the first end of the shaft 21. The mounting ring 22 has multiple radially protruding supports 221, which are correspondingly arranged with multiple sets of damping components 30. Two guide wheels 33 in each set of damping components 30 are rotatably mounted on the supports 221. The mounting ring 22 has a receiving cavity 222, and a second elastic buffer 223 is provided in the receiving cavity 222. By using the protruding supports 221, the guide wheels 33 can be mounted on the supports 221, and the guide wheels 33 are correspondingly arranged with the damping components 30.
[0048] In some embodiments, the sliding shaft 20 is provided with a cable groove 23 for cables to pass through, and the cable groove 23, the sliding shaft 20, and the housing 10 are coaxially arranged. The cable groove 23 allows cables to pass through, enabling electrical and communication connections between the multi-beam detection device 300 and equipment on the work vessel, thereby supplying power to the multi-beam detection device 300, sending commands, and transmitting data detected by the multi-beam detection device 300 back to the work vessel. By concealing the cables in the cable groove 23 of the sliding shaft 20, exposed cables are avoided, reducing the risk of interference between the cables and other structures in the housing 10, and improving the reliability of cable use. The coaxial arrangement of the cable groove 23, the sliding shaft 20, and the housing 10 improves the coaxiality of multiple components, thereby enhancing the balance of the damping stabilization device 100.
[0049] In some embodiments, the damping stabilizing device 100 further includes a conduit 40, one end of which is connected to the cable tray 23, and the other end is connected to the bottom cover 12 of the housing 10, and connected to the outside of the housing 10 through the bottom cover 12. The sliding shaft 20 is slidable relative to the conduit 40. The conduit 40 is used to connect the cable to the outside of the bottom cover 12, and the outside of the bottom cover 12 is used to install the multi-beam detection device 300. By providing the conduit 40, on the one hand, the conduit 40 can provide support and guidance for the sliding of the sliding shaft 20, improving the stability of the sliding shaft 20 during movement. On the other hand, the conduit 40 can accommodate the cable in the area outside the sliding shaft 20, thereby ensuring that the portion of the cable inside the entire housing 10 is isolated from other structures.
[0050] In some embodiments, the damping stabilizing device 100 further includes a stop plate 50. A mounting groove 51 is circumferentially provided on the outer periphery of the housing 10. The stop plate 50 is disposed within the mounting groove 51 and protrudes radially from the outer periphery of the housing 10. The surface of the stop plate 50 forms a stabilizing plane, which is perpendicular to the sliding shaft 20. By providing the stop plate 50, the contact area between the damping stabilizing device 100 and the seawater is increased, i.e., the force-bearing area between the damping stabilizing device 100 and the seawater is increased. Thus, the sloshing effect from the seawater can act more directly on the damping device. Utilizing the buffering and shock-absorbing effect of the damping device, the impact of seawater sloshing on the multi-beam detector 300 is eliminated or weakened, enhancing the stabilizing effect of the damping device. The mounting groove 51 on the outer periphery of the housing 10 allows the edge of the stop plate 50 to be engaged within the mounting groove 51, improving the connection strength between the stop plate 50 and the housing 10. Optionally, the stop plate 50 can be further connected to the mounting groove 51 using bolts, thereby enhancing the connection strength between the stop plate 50 and the mounting groove 51.
[0051] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
