Description

Technical Field

[0001] The present application relates to the technical field of underwater measurement devices, and in particular to a multi-beam detection device installation platform and detection equipment. Background Art

[0002] Multi-beam bathymetry systems are the mainstream equipment for depth measurement. They offer high accuracy, a large measurement area, fast measurement speed, and real-time, high-density three-dimensional depth point output. They are widely used in seabed topography and geomorphology surveys. The integrated planning, management, and protection of coastal zones (islands and reefs) is increasingly driven by the demand for subsurface topographic information. However, due to the influence of sea conditions, topography, and environmental factors in coastal zones (islands and reefs), depth measurement technology faces bottlenecks. For example, drone-based mapping can only be performed in intertidal zones at low tide, which imposes a strict operating window and limits the ability to map large areas. Airborne LiDAR measurements have strict requirements for water quality and depth, making laser point clouds difficult to penetrate nearshore areas with turbid water. GNSS RTK / PPK requires on-site personnel, resulting in low efficiency and high labor intensity. Furthermore, they cannot be used in areas with water depths exceeding one meter.

[0003] In related technologies, ship-borne multi-beam detection devices can be used to measure water depth. Multi-beam transducers are often fixed vertically, and the probes are emitted downward. In order to adapt to the unfavorable factors caused by the shallow water depth, large terrain changes, and complex hydrodynamic environment in coastal areas, islands and reefs, work vessels equipped with multi-beam detection devices can use small and highly flexible hulls such as small boats and small-tonnage workboats. However, this type of workboat is prone to poor stability. The hull shakes greatly due to the action of seawater, which causes the underwater multi-beam transducer to be in an unstable state, making it difficult to carry out large-scale measurements near the shore with a complex hydrodynamic environment.

[0040] The present application provides a detection device 500, which includes a multi-beam detection device 300 and a multi-beam detection device mounting platform 200. The multi-beam detection device 300 is disposed at the bottom of a housing 110. The detection device 500 utilizes the multi-beam detection device mounting platform 200 (hereinafter referred to as the mounting platform 200) to stably mount the multi-beam detection device 300 on a ship's side 400, thereby providing a reliable operating environment for the multi-beam detection device 300.

[0041] The structure of the installation platform 200 will be further introduced below.

[0042] See also Figures 2 to 4 The present application provides a multi-beam detection device mounting platform 200. This mounting platform 200 can be used to mount a multi-beam detection device 300 on an operating vessel, thereby enabling water depth measurement using the vessel-borne multi-beam detection device 300. The mounting platform 200 can provide a stable mounting environment for the multi-beam detection device 300, thereby improving the stability of the multi-beam detection device 300 during operation.

[0043] The installation platform 200 includes a connection assembly 210 and a damping stabilization device 100 . The connection assembly 210 includes a connection rod 211 , one end of which is connected to the ship's side 400 . The damping stabilizer 100 includes a housing 110, a sliding shaft 120, and a damping assembly 130. The first end of the sliding shaft 120 extends through the housing 110, and the second end of the sliding shaft 120 is connected to the other end of the connecting rod 211. The damping assembly 130 is disposed within the housing 110 and includes a flexible belt 131, a first elastic buffer 132, and at least two guide wheels 133. The two guide wheels 133 are disposed at the first end of the sliding shaft 120. The first elastic buffer 132 is disposed on the inner wall of one end of the housing 110. One end of the flexible belt 131 is fixed to the inner wall of one end of the housing 110. The flexible belt 131 is wound around the first elastic buffer 132 and the two guide wheels 133, and the other end of the flexible belt 131 is fixed to the inner wall of the other end of the housing 110. When the sliding shaft 120 moves axially relative to the housing 110, it can cause the first elastic buffer 132 to stretch or change the position of the guide wheels 133 within the flexible belt 131.

[0044] When the workboat is operating in the water, it will be impacted by the water flow, which manifests as the swaying of the hull. The swaying effect of the hull is transmitted to the sliding shaft 120 through the connecting rod 211, and then transmitted to the damping stabilization device 100 by the sliding shaft 120. At this time, relative movement will occur between the sliding shaft 120 and the shell 110. Since the flexible belt 131 is wound around the outer periphery of the first elastic buffer 132 and the two guide wheels 133, and the two ends of the flexible belt 131 are fixed to the inner walls of the two ends of the shell 110, this means that the total length of the flexible belt 131 is constant. Due to the swaying effect of the hull, the sliding shaft 120 can move along its own axial direction relative to the shell 110, thereby driving the guide wheels 133 to slide in the flexible belt 131, changing the position of the guide wheels 133 in the flexible belt 131. Therefore, by utilizing the buffering effect of the damping assembly 130, the kinetic energy of the sliding shaft 120 can be absorbed and converted into a change in the relative position of the sliding shaft 120 and the shell 110, so that the shell 110 remains basically stationary. At this time, the multi-beam detection device 300 installed on the shell 110 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 operation of the multi-beam detection device 300.

[0045] Furthermore, the impact of water flow on the damping stabilization device 100 can manifest as violent shaking or slight, slow shaking. In response to these two different situations, the first elastic buffer 132 can exhibit different effects. Specifically, when the sliding shaft 120 is subjected to a large instantaneous impact force, the guide wheel 133 drives the flexible belt 131 to tighten and pulls the first elastic buffer 132 to produce tensile deformation, thereby converting the large kinetic energy transmitted from the sliding shaft 120 into the deformation potential energy of the first elastic buffer 132. When the kinetic energy of the sliding shaft 120 disappears, the first elastic buffer 132 gradually returns to its original position. In this way, the large impact force of the sliding shaft 120 can be simultaneously converted into the deformation of the first elastic buffer 132 and the change in the relative position between the sliding shaft 120 and the housing 110, so that the housing 110 remains generally stable. When the sliding shaft 120 is subjected to a slow and smooth force, such as a slight vibration of the hull, the acceleration of the sliding shaft 120 is small. Therefore, the pulling force generated by the flexible belt 131 on the first elastic buffer 132 is small, and the first elastic buffer 132 hardly deforms. The relative sliding between the sliding shaft 120 and the shell 110 is used to eliminate slight impact effects.

[0046] For example, the flexible belt 131 may be a structure such as a rope or a chain, and the first elastic buffer 132 may be a tension spring or the like.

[0047] In some embodiments, the damping assembly 130 also includes a bracket 134, the bracket 134 includes a top wall 1341, a bottom wall 1342 and a side wall 1343, the shell 110 is provided with a top cover 111 and a bottom cover 112 along its own axis, the top wall 1341 is fixedly connected to the top cover 111, the bottom wall 1342 is fixedly connected to the bottom cover 112, and the two ends of the flexible belt 131 are respectively fixed to the top wall 1341 and the bottom wall 1342; the side wall 1343 is connected to the top wall 1341 and the side wall 1343, and a first sliding groove 13431 is provided on the side wall 1343, the first sliding groove 13431 is extended along the axial direction of the shell 110, and the rotating shaft of the guide wheel 133 is slidably connected to the first sliding groove 13431. The top wall 1341, bottom wall 1342, and side walls 1343 can be enclosed to form a certain space, thereby accommodating structures such as the flexible belt 131 and the first elastic buffer 132 within the space. On the one hand, this ensures that the damping assembly 130 provides an independent environment for the guide wheel 133, the flexible belt 131, etc. during use, preventing them from being entangled or interfering with other structures in the housing 110, thereby improving the independence and reliability of the damping assembly 130. On the other hand, this allows the damping assembly 130 to form an independent structure, making it easier to install the damping assembly 130 first and then install the entire assembly into the housing 110. The first sliding groove 13431 can provide guidance for the sliding of the guide wheel 133, making the sliding of the guide wheel 133 smoother and more stable.

[0048] In some embodiments, the damping assembly 130 further includes a fixed steering wheel 135 and a sliding steering wheel 136. The fixed steering wheel 135 is fixedly provided on one of the top wall 1341 or the bottom wall 1342, and the sliding steering wheel 136 is movably provided on the other of the top wall 1341 or the bottom wall 1342. The first elastic buffer 132 is connected to the sliding steering wheel 136, and the flexible belt 131 is connected to the first elastic buffer 132 via the sliding steering wheel 136. The flexible belt is sequentially wound around one of the guide wheels 133, the fixed steering wheel 135, the sliding steering wheel 136, and the other guide wheel 133. The provision of the fixed steering wheel 135 and the sliding steering wheel 136 allows the flexible belt 131 to be wound around and steered. The rolling action of the steering wheel helps reduce the friction and resistance of the flexible belt 131, thereby improving the sliding smoothness of the flexible belt 131. When the tension of the flexible belt 131 is small, the first elastic buffer member is hardly deformed, and the position of the sliding steering wheel 136 is hardly changed, that is, the sliding steering wheel 136 acts as a fixed pulley. When the tension of the flexible belt 131 is large, the first elastic buffer member is stretched and deformed, and the sliding steering wheel 136 acts as a movable pulley.

[0049] As an alternative embodiment, the fixed steering wheel 135 can also be replaced by a hook, a pull ring, or other structures, and the flexible belt 131 is inserted into the hook or the pull ring to achieve the steering effect of the flexible belt 131. In an embodiment where the sliding steering wheel 136 is not provided, the flexible belt 131 can also be directly slidably inserted into the first elastic buffer 132. For example, the flexible belt 131 is inserted into a spring, and the spring can be stretched and deformed under the tension of the flexible belt 131.

[0050] In some embodiments, the bottom wall 1342 of the bracket 134 is spaced apart from the bottom cover 112 of the housing 110 and defines a mounting space 113. The first elastic buffer 132 is accommodated in the mounting space 113. One end of the first elastic buffer 132 is fixedly connected to the bottom cover 112, and the other end is connected to the sliding steering wheel 136. The provision of the mounting space 113 allows the first elastic buffer 132 to be accommodated therein and provides sufficient space for deformation and resetting of the first elastic buffer 132.

[0051] In some embodiments, the side panel further includes a second sliding groove 13432, which is arranged parallel to the first sliding groove 13431. The rotating shaft of the sliding steering wheel 136 is slidably connected to the second sliding groove 13432. The second sliding groove 13432 can provide guidance for the movement of the sliding steering wheel 136, thereby improving the sliding stability and smoothness of the sliding steering wheel 136.

[0052] In some embodiments, see Figure 5Multiple groups of damping assemblies 130 are provided, and these groups are evenly spaced along the circumference of the housing 110. Providing multiple groups of damping assemblies 130 can provide multiple buffers for the impact of the sliding shaft 120, further improving the buffering and stabilizing effect of the damping stabilization device 100. The evenly spaced arrangement of the damping assemblies 130 along the circumference of the housing 110 can improve the force balance of the sliding shaft 120 when it moves relative to the housing 110, further enhancing the smoothness of the sliding of the sliding shaft 120.

[0053] In some embodiments, see Figure 6 The sliding shaft 120 includes a shaft 121 and a mounting ring 122. The first end of the shaft 121 is inserted into the housing 110, and the mounting ring 122 is sleeved around the outer circumference of the first end of the shaft 121. The mounting ring 122 is provided with a plurality of radially projecting supports 1221. The supports 1221 correspond to the plurality of damping assemblies 130. The two guide wheels 133 in each damping assembly 130 are rotatably mounted on the supports 1221. The mounting ring 122 has a receiving cavity 1222 disposed therein, and a second elastic buffer member 1223 is disposed therein. The projecting supports 1221 allow the guide wheels 133 to be mounted on the supports 1221, so that the guide wheels 133 are positioned correspondingly to the damping assemblies 130.

[0054] In some embodiments, the damping stabilization device 100 further includes a stop plate 150. A mounting groove 151 is circumferentially provided on the outer periphery of the housing 110. The stop plate 150 is disposed within the mounting groove 151. The stop plate 150 protrudes radially from the outer periphery of the housing 110. The surface of the stop plate 150 forms a stabilization plane perpendicular to the sliding shaft 120. The provision of the stop plate 150 increases the contact area between the damping stabilization device 100 and the seawater, thereby increasing the force-bearing area between the damping stabilization device 100 and the seawater. This allows the sloshing effect of the seawater to act more directly on the damping device. The damping device's buffering and shock-absorbing effect eliminates or weakens the impact of seawater sloshing on the multi-beam detection device 300, thereby enhancing the stabilization effect of the damping device. The mounting groove 151 provided on the outer periphery of the housing 110 allows the edge of the stop plate 150 to be snapped into the mounting groove 151, thereby increasing the connection strength between the stop plate 150 and the housing 110. Optionally, the stop plate 150 may be further connected to the mounting groove 151 using bolts, thereby enhancing the connection strength between the stop plate 150 and the mounting groove 151 .

[0055] In some embodiments, the sliding shaft 120 is provided with a first cable trough 123 for passing cables, and the connecting rod 211 is provided with a second cable trough 2111. One end of the connecting rod 211 is coaxially disposed with the sliding shaft 120 and detachably connected, and the first cable trough 123 and the second cable trough 2111 are arranged in communication. The connecting assembly 210 includes a connecting plate 212, which is disposed perpendicular to the connecting rod 211 and includes a first connecting segment 2121 and a second connecting segment 2122. The first connecting segment 2121 has a larger area than the second connecting segment 2122. The first connecting segment 2121 is used to connect to the ship's side 400, and the second connecting segment 2122 has a locking hole 2123, into which the other end of the connecting rod 211 is connected. By hiding the cables in the first and second cable troughs 123 and 2111, the cables are prevented from being exposed, the risk of interference between the cables and other structures in the housing 110 is reduced, and the reliability of the cables is improved. The coaxial arrangement of the connecting rod 211 and the sliding shaft 120 can improve the coaxiality of multiple components, thereby improving the balance of the damping stabilizer 100. By providing two connecting sections on the connecting plate 212, and setting the area of ​​the first connecting section 2121 to be larger than that of the second connecting section 2122, the contact area between the connecting plate 212 and the ship's side 400 can be increased when the first connecting section 2121 is connected to the ship's side 400, thereby improving the connection strength. Since the second connecting section 2122 only needs to be connected to the connecting rod 211, the area can be reduced, saving materials and reducing the weight of the connecting plate 212. By connecting the connecting rod 211 to the locking hole 2123, the connecting rod 211 and the connecting plate 212 can be fixed to each other, and the cable can pass through the locking hole 2123 and establish an electrical or communication connection with the equipment on the workboat.

[0056] The damping stabilizer 100 and the connecting assembly 210 are detachably connected. This allows for flexible selection of connecting assemblies 210 of varying specifications based on the height of the workboat, the target depth of the work location, and other factors, enabling adaptable installation of the damping stabilizer 100. Alternatively, the connecting rod 211 can be connected using multiple sections or a retractable structure, allowing the length of the connecting rod 211 to be flexibly adjusted based on the target depth of the work location, thereby enhancing assembly convenience.

[0057] Optionally, the damping stabilization device 100 further includes a conduit 140. One end of the conduit 140 is connected to the first cable trough 123, and the other end is connected to the bottom cover 112 of the housing 110. The conduit 140 is connected to the exterior of the housing 110 through the bottom cover 112. The sliding shaft 120 is slidable relative to the conduit 140. The conduit 140 is used to connect the cables to the exterior of the bottom cover 112. The exterior of the bottom cover 112 is used to mount the multi-beam detection device 300. The provision of the conduit 140 not only supports and guides the sliding of the sliding shaft 120, but also improves the stability of the sliding shaft 120 during movement. Furthermore, the conduit 140 can accommodate the cables in an area outside the sliding shaft 120, thereby ensuring that the portion of the cables within the entire housing 110 is isolated from other structures.

[0058] In some embodiments, see Figure 7 and Figure 8 The connecting assembly 210 also includes a locking structure 220, which includes two locking blocks 221. The two locking blocks 221 are respectively formed with locking grooves 2211. When the two locking blocks 221 are connected to each other, the two locking grooves 2211 enclose a locking hole 2123. The two locking blocks 221 are used to clamp and fix the other end of the connecting rod 211 in the locking hole 2123; the end of the locking block 221 away from the locking groove 2211 is also provided with a first hook 222, and the second connecting section 2122 of the connecting plate 212 is provided with a first groove 2124, and the first hook 222 and the first groove 2124 are matched and linked. By connecting the two locking blocks 221 to each other, the locking groove 2211 can be enclosed to form a locking hole 2123, and the connecting rod 211 can be clamped in the locking hole 2123. On the one hand, this achieves the fixation of the connecting rod 211; on the other hand, the way the two locking blocks 221 are connected to each other helps reduce the difficulty of installation and improve the installation efficiency of the connecting rod 211. For example, the two locking blocks 221 can be locked to each other by bolts. In this way, the two locking blocks 221 can provide sufficient clamping force for the connecting rod 211. The first hook 222 and the first slot 2124 are connected to each other by mutual cooperation. That is, the first slot 2124 is adapted to the shape of the first hook 222. In this way, the first hook 222 can be pushed into the first slot 2124 along the opening of the first slot 2124, thereby connecting the locking block 221 to the connecting plate 212. The use of a hook and slot engaging with each other not only improves the connection strength between the locking block 221 and the connecting plate 212, but also provides for convenient connection of the locking block 221. Optionally, after the first hook 222 is engaged with the first slot 2124, the locking block 221 can be further secured with a bolt to prevent the first hook 222 from slipping out of the first slot 2124.

[0059] In some embodiments, the connection assembly 210 further includes a socket 230 and a latch 240. The socket 230 includes a base 231 and a second hook 232 disposed on one side of the base 231. The second hook 232 is configured to engage with an edge of the ship's side 400. A side of the base 231 facing away from the second hook 232 forms a mounting surface 2311. The first connecting section 2121 of the connecting plate 212 is connected to the mounting surface 2311. The connecting plate 212 is provided with a through-hole 2125. The latch 240 is inserted into the hole 2125, with one side surface of the latch 240 abutting against the outer side of the socket 230 and the ship's side 400. By providing the socket 230 and utilizing a side surface of the base 231 of the socket 230 as the mounting surface 2311 for connection to the connecting plate 212, the contact area between the socket 230 and the connecting plate 212 is increased, thereby improving the connection strength and thereby enhancing the installation stability of the connecting plate 212. The second hook 232 of the holder 230 can adapt to the edge shape of the ship's side 400, allowing the connecting plate 212 to be stably connected to the ship's side 400. For example, the top of the ship's side 400 has a flange structure 410, and the second hook 232 of the holder 230 can precisely engage with the flange structure 410. That is, the flange structure 410 of the ship's side 400 snaps into the second hook 232, and the two engage with each other, thereby stably mounting the holder 230 on the ship's side 400. For example, the holder 230 and the connecting plate 212 can be fixedly connected by bolts. The plugging action of the pin 240 and the socket 2125 further provides positioning and anti-rotation for the connecting plate 212 and the holder 230, preventing the connecting plate 212 from rotating relative to the holder 230 on the plane of the mounting surface 2311, thereby improving the stability and installation accuracy of the connection between the connecting plate 212 and the holder 230.

[0060] In some embodiments, see Figure 9The multi-beam detection device mounting platform 200 also includes an angle adjustment assembly 250, which includes a first driving member 251, a second driving member 252, a third driving member 253, a rocker arm 254 and a connecting rod 255. The first driving member 251 is installed on the outside of the bottom cover 112 of the shell 110, one end of the rocker arm 254 is connected to the first driving member 251, and the other end is connected to the second driving member 252. The first driving member 251 drives the rocker arm 254 to rotate in a plane perpendicular to the axial direction of the shell 110, one end of the connecting rod 255 is connected to the second driving member 252, and the other end of the connecting rod 255 is connected to the third driving member 253. The second driving member 252 is used to adjust the angle between the rocker arm 254 and the connecting rod 255. The third driving member is used to connect the multi-beam detection device 300, and the third driving member 253 drives the multi-beam detection device 300 to rotate with the third driving member 253 as the axis. The first drive member 251 drives the rocker arm 254 to rotate, giving the multi-beam detection device 300 a first degree of freedom of movement with the rotation axis of the first drive member 251 as the center. The second drive member 252 changes the angle between the rocker arm 254 and the connecting rod 255, giving the multi-beam detection device 300 a second degree of freedom of movement with the rotation axis of the second drive member 252 as the center. The third drive member 253 drives the multi-beam detection device 300 to rotate, allowing the multi-beam detection device 300 to rotate around the rotation axis of the third drive member 253, thus giving it a third degree of freedom of movement. Therefore, by using the angle adjustment assembly 250 to mount the multi-beam detection device 300 on the housing 110 of the damping device, the multi-beam detection device 300 can have three degrees of freedom of movement, meeting detection requirements at different angles and positions, thereby improving the flexibility of the multi-beam detection device 300.

[0061] Exemplarily, the first driving member 251 , the second driving member 252 , and the third driving member 253 may all be motors.
