Description

Technical Field

[0001] This application relates to the technical field of underwater measurement devices, and particularly to a mounting platform for a multi-beam detection device and a detection device. Background Art

[0002] The multi-beam sounding system is the mainstream equipment for water depth measurement, with characteristics such as high measurement accuracy, large measurement area, fast measurement speed, and real-time three-dimensional high-density water depth point output, and is widely used in submarine topography and geomorphology measurement work. Currently, the demand for underground topographic information in the integrated planning, management, and protection work of the coastal zone (island reef) is increasing day by day. However, due to the influence of sea conditions, topography, environment, etc. in the coastal zone (island reef) area, there are technical bottlenecks in water depth measurement. For example, UAV mapping can only carry out intertidal zone mapping at low tide, which has requirements for the operation window and limits the large-area mapping ability; while airborne LiDAR measurement has high requirements for water quality and water depth, and it is difficult for laser point clouds to penetrate in areas with turbid nearshore water quality; GNSS RTK / PPK requires on-site operation by personnel, with low measurement operation efficiency, high labor intensity, and inability to operate in areas with a water depth exceeding 1 meter.

[0003] In related technologies, an on-board multi-beam detection device can be used for water depth measurement. The multi-beam transducer is often vertically fixedly installed with the probe facing downward. To adapt to the adverse factors caused by the relatively shallow water depth, large terrain changes, and complex hydrodynamic environment in coastal waters such as the coastal zone and island reefs, the operation ship carrying the multi-beam detection device can use a hull with a small volume and high flexibility, such as a small boat or a small-tonnage operation ship. However, such an operation ship is prone to the problem of poor stability, and the hull shakes greatly under the action of seawater, resulting in an unstable attitude of the underwater multi-beam transducer and making it difficult to carry out large-scale measurements in the nearshore with a complex hydrodynamic environment.

The shaking of the hull is transmitted to the sliding shaft through the connecting rod, and then to the damping and stabilizing device by the sliding shaft. At this time, relative movement will occur between the sliding shaft and the housing. Since the flexible belt is wound around the outer circumference of the first elastic buffer member and the two guide wheels, and both ends of the flexible belt are fixed on the inner walls at both ends of the housing, this means that the total length of the flexible belt is constant.

Therefore, by using 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, so that the housing basically remains stationary. At this time, the multi-beam detection device installed on the housing can obtain a stable working environment, ensuring that the multi-beam detection device can maintain a good posture during operation, thereby improving the reliability and accuracy of the multi-beam detection device during operation.

[0024] 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 the housing 110. The detection device 500 uses 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 the ship's side 400, thereby providing a reliable working environment for the multi-beam detection device 300.

[0025] The structure of the mounting platform 200 will be further introduced below.

[0026] Please refer to Figures 2 to 4 , the present application provides a multi-beam detection device mounting platform 200, which can be used to mount the multi-beam detection device 300 on a workboat, so as to perform water depth measurement using the on-board multi-beam detection device 300. The mounting platform 200 can provide a stable mounting environment for the multi-beam detection device 300 and improve the stability of the multi-beam detection device 300 during operation.

[0027] The mounting platform 200 includes a connection component 210 and a damping and stabilizing device 100. The connection component 210 includes a connecting rod 211, and one end of the connecting rod 211 is connected to the ship's side 400. The damping and stabilizing device 100 includes a housing 110, a sliding shaft 120, and a damping component 130. The first end of the sliding shaft 120 penetrates through the housing 110, the second end of the sliding shaft 120 is connected to the other end of the connecting rod 211, the damping component 130 is disposed in the housing 110, the damping component 130 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 outer circumferences of 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. Wherein, when the sliding shaft 120 moves axially relative to the housing 110, it can drive the first elastic buffer 132 to stretch or change the position of the guide wheels 133 in the flexible belt 131.

[0028] When the workboat is operating in water, it will be impacted by the water flow and show as the hull's swaying. The swaying of the hull is transmitted to the sliding shaft 120 through the connecting rod 211, and then from the sliding shaft 120 to the damping and stabilizing device 100. At this time, relative movement will occur between the sliding shaft 120 and the housing 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 both ends of the flexible belt 131 are fixed on the inner walls at both ends of the housing 110, this means that the total length of the flexible belt 131 is constant. Due to the swaying of the hull, the sliding shaft 120 can move axially relative to the housing 110, thereby driving the guide wheels 133 to slide in the flexible belt 131 and changing the positions of the guide wheels 133 in the flexible belt 131. Therefore, by using the buffering effect of the damping component 130, the kinetic energy of the sliding shaft 120 can be absorbed and converted into the change of the relative position between the sliding shaft 120 and the housing 110, so that the housing 110 basically remains stationary. At this time, the multi-beam detection device 300 installed on the housing 110 can obtain a stable operating environment, ensuring that the multi-beam detection device 300 can maintain a good attitude during operation, thereby improving the reliability and accuracy of the operation of the multi-beam detection device 300.

[0029] Furthermore, the impact of the water flow on the damping and stabilizing device 100 can be manifested as violent swaying or slight and slow swaying. For these two different situations, the first elastic buffer 132 can show different effects. Specifically, when the sliding shaft 120 is subjected to an instantaneous large impact force, the guide wheel 133 drives the flexible belt 131 to be tightened, and pulls the first elastic buffer 132 to produce tensile deformation. Thus, the large kinetic energy transmitted from the sliding shaft 120 is converted 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 of the relative position between the sliding shaft 120 and the housing 110, making the housing 110 generally maintain a stable state. When the sliding shaft 120 is subjected to a slow and smooth force, such as a weak vibration of the hull, that is, the acceleration of the sliding shaft 120 is small at this time, so 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 slight impact is eliminated by the relative sliding between the sliding shaft 120 and the housing 110.

[0030] Exemplarily, the flexible belt 131 can be structures such as ropes and chains, and the first elastic buffer 132 can be a tension spring, etc.

[0031] In some embodiments, the damping assembly 130 further includes a bracket 134. The bracket 134 includes a top wall 1341, a bottom wall 1342, and a side wall 1343. The housing 110 is provided with a top cover 111 and a bottom cover 112 along its own axial direction. The top wall 1341 is fixedly connected to the top cover 111, and the bottom wall 1342 is fixedly connected to the bottom cover 112. 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. A first sliding groove 13431 is provided on the side wall 1343. The first sliding groove 13431 extends along the axial direction of the housing 110. The rotating shaft of the guide wheel 133 is slidably connected in the first sliding groove 13431. By using the top wall 1341, the bottom wall 1342, and the side wall 1343, a certain space can be enclosed with each other, so as to accommodate structures such as the flexible belt 131 and the first elastic buffer 132 in this space. On the one hand, it can ensure that the damping assembly 130 provides an independent environment for the guide wheel 133, the flexible belt 131, etc. during use, avoiding entanglement or interference with other structures in the housing 110, and improving the independence and reliability of the damping assembly 130 in use. On the other hand, this can enable the damping assembly 130 to form an independent structure, facilitating the installation of the damping assembly 130 as a whole into the housing 110 after the damping assembly 130 is installed first. By using the first sliding groove 13431, a guiding effect can be provided for the sliding of the guide wheel 133, making the sliding of the guide wheel 133 smoother and more stable.

[0032] In some embodiments, the damping assembly 130 further includes a fixed steering wheel 135 and a sliding steering wheel 136. One of the top wall 1341 or the bottom wall 1342 is fixedly provided with the fixed steering wheel 135, and the other of the top wall 1341 or the bottom wall 1342 is movably provided with the sliding steering wheel 136. The first elastic buffer 132 is connected to the sliding steering wheel 136. The flexible belt 131 is connected to the first elastic buffer 132 through the sliding steering wheel 136. The flexible belt sequentially winds around one of the guide wheels 133, the fixed steering wheel 135, the sliding steering wheel 136, and the other guide wheel 133. By providing the fixed steering wheel 135 and the sliding steering wheel 136, it can be used to wind the flexible belt 131 and realize the steering of the flexible belt 131. The rolling effect of the steering wheel helps to reduce the friction and resistance of the flexible belt 131 and improve the sliding smoothness of the flexible belt 131. When the pulling force of the flexible belt 131 is relatively small, the first buffer elastic member hardly deforms, and at this time, the position of the sliding steering wheel 136 hardly changes, that is, the sliding steering wheel 136 functions as a fixed pulley. When the pulling force of the flexible belt 131 is relatively large, the first buffer elastic member will be stretched and deformed, and at this time, the sliding steering wheel 136 functions as a movable pulley.

[0033] As an alternative embodiment, the fixed steering wheel 135 can also be replaced with structures such as hooks and rings. The flexible belt 131 is threaded through the hook or ring, thereby realizing the steering function of the flexible belt 131. In the embodiment without the sliding steering wheel 136, the flexible belt 131 can also directly slide through the first elastic buffer 132. For example, the flexible belt 131 is threaded through a spring, and the spring can be stretched under the pulling force of the flexible belt 131.

[0034] In some embodiments, the bottom wall 1342 of the bracket 134 is spaced from the bottom cover 112 of the housing 110 and forms an installation space 113. The first elastic buffer 132 is received in the installation 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. By providing the installation space 113, the first elastic buffer 132 can be accommodated therein, and sufficient space is provided for the deformation and reset of the first elastic buffer 132.

[0035] In some embodiments, a second sliding groove 13432 is further provided on the side plate. The second sliding groove 13432 is arranged in parallel with the first sliding groove 13431. The rotating shaft of the sliding steering wheel 136 is slidably connected in the second sliding groove 13432. The second sliding groove 13432 can provide a guiding effect for the movement of the sliding steering wheel 136, improving the sliding stability and smoothness of the sliding steering wheel 136.

[0036] In some embodiments, please refer to Figure 5 that multiple sets of damping components 130 are provided in the damping assembly 130, and the multiple sets of damping components 130 are arranged at equal intervals along the circumferential direction of the housing 110. By providing multiple sets of damping components 130, multiple buffers can be provided for the impact of the sliding shaft 120, further improving the buffering and stabilizing effect of the damping stabilizing device 100. The damping components 130 are arranged at equal intervals along the circumferential direction of the housing 110, which can improve the force balance when the sliding shaft 120 moves relative to the housing 110, and further improve the smoothness of the sliding of the sliding shaft 120.

[0037] In some embodiments, please refer to Figure 6 that the sliding shaft 120 includes a shaft rod 121 and a mounting ring 122. The first end of the shaft rod 121 penetrates through the housing 110, and the mounting ring 122 is sleeved on the outer periphery of the first end of the shaft rod 121. A plurality of supports 1221 protrude radially from the mounting ring 122, and the supports 1221 are arranged in one-to-one correspondence with the multiple sets of damping components 130. Two guide wheels 133 in each set of damping components 130 are rotatably mounted on the supports 1221; a receiving cavity 1222 is provided inside the mounting ring 122, and a second elastic buffer 1223 is provided in the receiving cavity 1222. By using the protruding supports 1221, the guide wheels 133 can be mounted on the supports 1221 and the guide wheels 133 can be arranged corresponding to the damping components 130.

[0038] In some embodiments, the damping and stabilizing device 100 further includes a stop plate 150. An installation groove 151 is circumferentially provided on the outer periphery of the housing 110. The stop plate 150 is disposed in the installation groove 151. The stop plate 150 protrudes radially from the outer peripheral side surface of the housing 110. A stability maintaining plane is formed on the surface of the stop plate 150, and the stability maintaining plane is perpendicular to the sliding shaft 120. By providing the stop plate 150, the contact area between the damping and stabilizing device 100 and seawater can be increased, that is, the force-bearing area between the damping and stabilizing device 100 and seawater can be increased. In this way, the swaying action from seawater can more directly act on the damping device, and by using the buffering and shock-absorbing effect of the damping device, the influence of seawater swaying on the multi-beam detection device 300 can be eliminated or weakened, and the stabilizing effect of the damping device can be enhanced. By providing the installation groove 151 on the outer peripheral side surface of the housing 110, the edge of the stop plate 150 can be clamped in the installation groove 151, thereby improving the connection strength between the stop plate 150 and the housing 110. Optionally, the stop plate 150 and the installation groove 151 can be further connected by bolts, so as to enhance the connection strength between the stop plate 150 and the installation groove 151.

[0039] 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.

[0040] 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.

[0041] Optionally, the damping and stabilizing device 100 is further provided with a conduit 140. One end of the conduit 140 communicates with the first cable trough 123, and the other end is connected to the bottom cover 112 of the housing 110 and communicates with the outside 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 cable to the outside of the bottom cover 112, and the outside of the bottom cover 112 is used to install the multi-beam detection device 300. By providing the conduit 140, on the one hand, the conduit 140 can provide support and guidance for the sliding of the sliding shaft 120, improving the stability of the sliding shaft 120 during movement. On the other hand, the conduit 140 can accommodate the cable in the area outside the sliding shaft 120, thus ensuring that the part of the cable inside the entire housing 110 is isolated from other structures.

[0042] In some embodiments, referring to Figure 7 and Figure 8 , the connecting assembly 210 further includes a locking structure 220. The locking structure 220 includes two locking blocks 221. Locking grooves 2211 are respectively formed on the two locking blocks 221. When the two locking blocks 221 are connected to each other, the two locking grooves 2211 enclose to form 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; a first hook 222 is further provided at one end of the locking block 221 away from the locking groove 2211, and a first card slot 2124 is provided on the second connecting section 2122 of the connecting plate 212. The first hook 222 and the first card slot 2124 are cooperatively linked. By connecting the two locking blocks 221 to each other, the locking grooves 2211 can be enclosed to form the locking hole 2123, and the connecting rod 211 can be clamped in the locking hole 2123. On the one hand, the fixing of the connecting rod 211 is realized; on the other hand, the way of docking the two locking blocks 221 with each other helps to reduce the installation difficulty and improve the installation efficiency of the connecting rod 211. Exemplarily, 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. By using the first hook 222 and the first card slot 2124 to be cooperatively connected, that is, the shape of the first card slot 2124 is adapted to the first hook 222. In this way, the first hook 222 can be pushed into the first card slot 2124 along the opening of the first card slot 2124 to realize the connection between the locking block 221 and the connecting plate 212. The way of clamping the hook and the card slot not only can improve the connection strength between the locking block 221 and the connecting plate 212, but also can take into account the connection convenience of the locking block 221. Optionally, after the first hook 222 is inserted into the first card slot 2124, bolts can be used to further fix the locking block 221 to prevent the first hook 222 from slipping out of the first card slot 2124.

[0043] In some embodiments, the connecting component 210 further includes a card seat 230 and a plug pin 240. The card seat 230 includes a substrate 231 and a second hook 232 disposed on one side of the substrate 231. The second hook 232 is used for snap-connecting with the edge of the ship's side 400. The side of the substrate 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. A through hole 2125 is provided on the connecting plate 212. The plug pin 240 is inserted into the through hole 2125, and one side surface of the plug pin 240 abuts against the outer side surfaces of the card seat 230 and the ship's side 400. By providing the card seat 230 and using one side surface of the substrate 231 of the card seat 230 as the mounting surface 2311 and connecting the mounting surface 2311 with the connecting plate 212, the contact area between the card seat 230 and the connecting plate 212 can be increased, the connection strength can be improved, and thus the mounting stability of the connecting plate 212 can be improved. The second hook 232 of the card seat 230 can adapt to the edge shape of the ship's side 400, so that the connecting plate 212 can be stably connected to the ship's side 400. Exemplarily, the top end of the ship's side 400 has a flanging structure 410, and the second hook 232 of the card seat 230 can just snap-connect with the flanging structure 410, that is, the flanging structure 410 of the ship's side 400 is snapped into the second hook 232, and the two are engaged with each other, so that the card seat 230 is stably mounted on the ship's side 400. Exemplarily, the card seat 230 and the connecting plate 212 can be fixedly connected by bolts. Through the insertion action of the plug pin 240 and the through hole 2125, the connecting plate 212 and the card seat 230 can be further positioned and anti-rotated, preventing the connecting plate 212 from rotating relative to the card seat 230 on the plane of the mounting surface 2311, thereby improving the connection stability and mounting accuracy between the connecting plate 212 and the card seat 230.

[0044] In some embodiments, please refer to Figure 9, the installation platform 200 of the multi-beam detection device further includes an angle adjustment component 250. The angle adjustment component 250 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 outer side of the bottom cover 112 of the housing 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 axis of the housing 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 point driving member is used to connect the multi-beam detection device 300. The third driving member 253 drives the multi-beam detection device 300 to rotate about the axis of the third driving member 253. By driving the rocker arm 254 to rotate with the first driving member 251, the multi-beam detection device 300 has a first-degree-of-freedom of movement centered on the rotation axis of the first driving member 251; by using the second driving member 252 to change the included angle between the rocker arm 254 and the connecting rod 255, the multi-beam detection device 300 has a second-degree-of-freedom of movement centered on the rotation axis of the second driving member 252; by using the third driving member 253 to drive the multi-beam detection device 300 to rotate, at this time, the multi-beam detection device 300 can rotate about the rotation axis of the third driving member 253, that is, it has a third-degree-of-freedom of movement. Therefore, by using the angle adjustment component 250 to install 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 the detection requirements at different angles and positions, thereby improving the flexibility of the movement of the multi-beam detection device 300.

[0045] Exemplarily, the first driving member 251, the second driving member 252, and the third driving member 253 can all be motors.
