Description

Technical Field

[0001] This invention relates to the field of marine monitoring, and more particularly to a water area mapping device for marine engineering surveying. Background Technology

[0002] In recent years, with the rapid development of marine resource development and marine engineering construction, the demand for accurate mapping and long-term monitoring of underwater topography, geological structures, and artificial facilities (such as artificial reefs, pipelines, and cables) has been increasing. Traditional marine mapping devices mostly adopt the method of direct deployment to the seabed and data acquisition using camera units or sensors. Such devices typically include a platform on which monitoring equipment (such as panoramic cameras, sonar, and water quality sensors) is installed to achieve observation and data recording of the seabed environment or specific targets.

[0003] An investigation revealed that Chinese invention patent CN117915170A discloses a real-time automatic detection device for underwater artificial reefs, comprising: a platform on which a monitoring and surveillance equipment assembly is mounted; the monitoring and surveillance equipment assembly includes a panoramic camera assembly; a cleaning brush head vertically mounted on the platform is positioned above the top spherical surface of the panoramic camera assembly; a drive rod rotatably connected to the platform is mounted on the cleaning brush head; and a flow guide pipe positioned above the cleaning brush head, with an adsorption cover opening towards the cleaning brush head connected to its bottom. This invention achieves real-time automatic monitoring by using the monitoring and surveillance equipment assembly mounted on the platform to monitor data from seabed monitoring points. It also enables long-term monitoring of marine ranches and can transport cleaned debris to a location away from the automatic detection device, preventing debris from falling back onto the platform and affecting cleaning efficiency.

[0004] However, due to the unevenness of the seabed surface and the presence of complex geological conditions such as mud, gravel, and reefs, if the base of the device does not make sufficient contact with the seabed or sinks into soft sediments when it lands, the platform may tilt or even collapse. Local undulations in the seabed topography may also cause the device to be in an unstable state. This physical imbalance will directly cause the monitoring equipment to deviate from the preset orientation. Even slight tilting will accumulate errors during long-term monitoring, resulting in data distortion and, in severe cases, even equipment failure. On the other hand, the speed and direction of seabed currents are complex and variable, especially in reef areas and slopes where eddies or impingement currents are easily formed. When the device is placed on the seabed, the current will exert continuous or uneven thrust on the device, causing it to shift or tilt. If the platform cannot maintain horizontal stability, the observation angle and coverage of the monitoring equipment (such as panoramic cameras and sonar probes) on it will deviate, thus affecting the consistency and accuracy of the data.

[0005] Therefore, a water area surveying device for marine engineering surveying was designed. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a marine surveying device for marine engineering surveying. It solves the problems of existing devices having poor resistance to water flow and uneven seabed, and being prone to tilting, displacement, or even tipping over during long-term static monitoring, which leads to data distortion, equipment damage, or mission interruption, seriously affecting the reliability of high-precision surveying and long-term observation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A marine engineering surveying device includes a support platform, multiple slots on the support platform, a mounting frame fixedly mounted on the top of the support platform, monitoring equipment mounted on the mounting frame, support legs fixedly mounted at the four corners at the bottom of the support platform, contact seats located at the bottom of the support legs, and electric push rods installed inside or on one side of the support legs for individually adjusting the height of the corresponding contact seats to adapt to different seabed conditions.

[0008] Preferably, a control terminal is provided on the mounting bracket, and a pressure sensor is fixedly provided at the bottom of the contact seat. The pressure sensor and the electric push rod are electrically connected to the input and output terminals of the control terminal, respectively.

[0009] Preferably, the contact seat is provided with a plurality of stable legs arranged in a circumferential array on its exterior, and one end of the plurality of stable legs is hinged to the same fixed plate.

[0010] Preferably, each of the plurality of stabilizing legs is provided with a connecting rod, and a movable sleeve is provided above the pressure sensor. The two ends of the connecting rod are respectively hinged to the stabilizing leg and the movable sleeve.

[0011] Preferably, the fixed plate is provided with a drive mechanism for driving the movable sleeve to move up and down to adjust the position of the contact seat.

[0012] Preferably, the drive mechanism includes a threaded rod fixedly disposed at the top center of the contact seat and threadedly connected to the movable sleeve, and a motor fixedly disposed at the top of the threaded rod and fixedly connected to the fixed plate; the motor is fitted with a protective cover fixedly connected to the fixed plate, and the top of the protective cover is fixedly connected to the support leg.

[0013] Preferably, the threaded rod is rotatably connected to the fixed disc, and telescopic sleeve rods are fixedly provided on both the top and bottom sides of the movable sleeve. The telescopic sleeve rods are sleeved on the outside of the threaded rod to protect the threaded rod and prevent it from getting stuck on the seabed.

[0014] Preferably, a connecting mesh for increasing the contact area with the ground is provided on the side of the plurality of stabilizing legs away from the fixed plate. The connecting mesh is made of a flexible polymer material resistant to seawater corrosion, preferably woven from nylon or polyester fiber. A plurality of fixing sleeves are fixedly provided on the connecting mesh, and the plurality of fixing sleeves are respectively fixedly fitted on the plurality of stabilizing legs. A circular groove is provided at the center of the fixing sleeve for accommodating the contact seat, so that the pressure sensor can be exposed and in direct contact with the ground.

[0015] Preferably, multiple sealing covers are fixedly installed on the outer wall of the mounting frame. The sealing covers are made of transparent acrylic material, which are used to protect the monitoring equipment while allowing it to monitor the seabed conditions and transmit the monitoring data to the control terminal for water area mapping. A hook is fixedly installed on the top of the mounting frame to facilitate the slinging of the entire device to the seabed. Stable frames are fixedly installed around the mounting frame and fixedly connected to the four corners of the top of the support legs to enhance the structural stability of the entire device.

[0016] Preferably, the motor is electrically connected to the output of the control terminal. When the control terminal detects that the pressure value of the pressure sensor at the bottom of any contact seat is greater than a preset threshold, it controls the motor at the top of the contact seat to run, driving the moving sleeve to move downwards. This causes the stable legs around the contact seat on the side in contact with the ground to open outwards via the connecting rod. For the remaining contact seats that do not detect a valid pressure value, the control terminal controls the electric push rod at the top of the contact seat to run, pushing the contact seat downwards until it contacts the ground and the pressure value reaches the threshold. Then, it controls the motor at that location to run, causing the stable legs around it to open and simultaneously unfold the connecting net to enhance the overall stability of the device.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a pressure sensor in conjunction with an electric push rod to achieve independent and automatic adjustment of the length of each support leg. The pressure sensor can detect the undulations of the seabed topography in real time and actively adjust the support posture to ensure that the support platform can quickly reach and maintain a horizontal state in complex sea conditions. This solves the problems of monitoring equipment perspective deviation and observation data distortion caused by platform tilt in traditional devices, and improves the accuracy, consistency and reliability of underwater mapping data. Based on the precise leveling, the device further forms a large-area adsorption support surface on the seabed by using deployable stable legs in combination with a high-performance flexible connecting net. This increases the contact area between the device and the seabed substrate, which not only enhances the device's resistance to water flow impact and overturning stability, but also effectively disperses the pressure exerted by the device on the seabed. This significantly reduces the risk of sinking on silt or soft seabeds, ensuring the structural stability and data continuity of the equipment during long-term continuous monitoring missions. The sealing cover, made of high-transmittance acrylic material, provides reliable pressure protection for underwater monitoring equipment while offering a good field of view, effectively improving monitoring quality and enhancing overall environmental adaptability. It is especially suitable for high-precision, long-cycle marine engineering surveying and ecological monitoring tasks. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0025] Please see Figure 1-7 A marine engineering surveying device includes a support platform 1, multiple slots 11 opened on the support platform 1, a mounting frame 2 fixedly installed on the top of the support platform 1, a monitoring device 3 installed on the mounting frame 2, support legs 4 fixedly installed at the four corners at the bottom of the support platform 1, contact seats 5 located at the bottom of the support legs 4, and an electric push rod 6 installed inside or on one side of the support legs 4 for individually adjusting the height of the corresponding contact seats 5 to adapt to different seabed conditions. The mounting bracket 2 is equipped with a control terminal 24. A pressure sensor 51 is fixedly installed at the bottom of the contact seat 5. The pressure sensor 51 and the electric push rod 6 are electrically connected to the input and output ends of the control terminal 24, respectively. Multiple stable legs 52 arranged in a circular array are provided on the outside of the contact seat 5. One end of the multiple stable legs 52 is hinged to the same fixed plate 53. Each of the multiple stable legs 52 is equipped with a connecting rod 54. A movable sleeve 55 is provided above the pressure sensor 51. The two ends of the connecting rod 54 are hinged to the stable legs 52 and the movable sleeve 55, respectively. The fixed plate 53 is equipped with a drive mechanism 7 for driving the movable sleeve 55 to move up and down to adjust the position of the contact seat 5. The water mapping device is lowered to the seabed by the hook 22 at the top of the mounting frame 2. Under the action of gravity, the contact seats 5 at the ends of the four support legs 4 successively contact the uneven seabed. The pressure sensor 51 at the bottom of each contact seat 5 transmits the sensed pressure signal to the control terminal 24 in real time. The readings of each sensor are different. If some readings are zero, it means that the leg is suspended. The control terminal 24 receives the data from the four pressure sensors 51 and performs analysis and judgment. For support leg 4 whose pressure value does not reach the preset threshold, i.e., does not effectively contact the ground, the control terminal 24 will issue a command to drive the electric push rod 6 on that side to extend and push the contact seat 5 below it to move downward until the pressure sensor 51 on that side also detects an effective pressure signal, thus achieving the initial horizontal leveling of the device and ensuring that all four support points have reliably contacted the seabed, laying the foundation for subsequent stable operation. Once a contact seat 5 confirms contact with the ground, if the pressure value of the pressure sensor 51 at its bottom exceeds the threshold, the control terminal 24 will activate the drive mechanism 7 on that side to enhance stability. Example

[0026] The drive mechanism 7 includes a threaded rod 71 fixedly disposed at the top center of the contact seat 5 and threadedly connected to the movable sleeve 55, and a motor 72 fixedly disposed at the top of the threaded rod 71 and fixedly connected to the fixed plate 53. The motor 72 is fitted with a protective cover 721 fixedly connected to the fixed plate 53. The top of the protective cover 721 is fixedly connected to the support leg 4. The threaded rod 71 is rotatably connected to the fixed plate 53. Telescopic sleeve rods 73 are fixedly disposed on both the top and bottom sides of the movable sleeve 55. The telescopic sleeve rods 73 are fitted on the outside of the threaded rod 71 to protect the threaded rod 71 and prevent the threaded rod 71 from getting stuck on the seabed. A connecting net 8 is provided on the side of the multiple stable outriggers 52 away from the fixed plate 53 to increase the contact area with the ground. The connecting net 8 is made of a flexible polymer material that is resistant to seawater corrosion, preferably nylon or polyester fiber. Multiple fixing sleeves 81 are fixedly installed on the connecting net 8. The multiple fixing sleeves 81 are respectively fixedly installed on the multiple stable outriggers 52. A circular groove 82 is opened in the center of the fixing sleeve 81 to accommodate the contact seat 5, so that the pressure sensor 51 can be exposed and directly contact the ground. After the device is initially leveled, the local stability is further enhanced by the combined use of the drive mechanism 7 and the stabilizing legs 52. When the pressure sensor 51 at the bottom of a certain support leg 4 detects effective pressure and that it has contacted the ground, the signal is uploaded to the control terminal 24. The terminal then sends a start command to the motor 72 on that side. The motor 72 starts, and its output shaft drives the threaded rod 71 to rotate. Since the threaded rod 71 and the movable sleeve 55 are threadedly connected, and the movable sleeve 55 is restricted from rotating by the telescopic sleeve rod 73, the rotational motion is converted into linear motion, driving the movable sleeve 55 to move smoothly downward along the threaded rod 71. As the movable sleeve 55 moves downward, it pushes the stabilizing legs 52 through the connecting rod 54 that is hinged to it. One end of the stabilizing legs 52 is hinged to the fixed plate 53. Therefore, under the thrust of the connecting rod 54, multiple stabilizing legs 52 unfold outward. As the stabilizing legs 52 unfold, the connecting net 8 fixedly sleeved on them... It is opened synchronously, like an inverted umbrella, and laid flat or covered on the seabed. The circular groove 82 in the center of the fixing sleeve 81 ensures that when the connecting net 8 is unfolded, the contact seat 5 and the pressure sensor 51 still maintain direct contact with the ground, without affecting the initial leveling sensing function. It greatly enhances the ability to resist lateral water flow impact. After the connecting net 8 is unfolded, the contact form with the seabed changes from point to surface. The net surface woven by high-strength fibers can cover and fit the uneven seabed to the maximum extent. Its flexible nature allows the net wires to be embedded in the tiny gaps of mud and sand, generating friction and effectively resisting the impact of ocean currents from all directions. The telescopic sleeve 73 completely encloses the key threaded rod 71 and threaded pair, forming a robust barrier that effectively isolates seawater, silt, and marine life from direct contact and interference, reducing the risk of jamming and corrosion.

[0027] In some embodiments, multiple sealing covers 21 are fixedly installed on the outer wall of the mounting frame 2. The sealing covers 21 are made of transparent acrylic material, which are used to protect the monitoring equipment 3 while allowing it to monitor the seabed conditions and transmit the monitoring data to the control terminal 24 for water area mapping. A hook 22 is fixedly installed on the top of the mounting frame 2 to facilitate the hoisting of the entire device to the seabed. Stable frames 23 are fixedly installed around the mounting frame 2 and are fixedly connected to the four corners of the top of the support legs 4 to enhance the structural stability of the entire device. The motor 72 is electrically connected to the output of the control terminal 24. When the control terminal 24 detects that the pressure value of the pressure sensor 51 at the bottom of any contact seat 5 is greater than the preset threshold, it controls the motor 72 at the top of the contact seat 5 to run, drives the moving sleeve 55 to move down, and causes the stable support legs 52 around the contact seat 5 on the side in contact with the ground to open outward through the connecting rod 54. For the remaining contact seats 5 that do not detect a valid pressure value, the control terminal 24 controls the electric push rod 6 on its top to move, pushing the contact seat 5 down until it contacts the ground and the pressure value reaches the threshold. Then, it controls the motor 72 at that location to open the stable support legs 52 around it and drive the connecting net 8 to unfold synchronously to enhance the overall stability of the device.

[0028] Through the design of deployable stabilizing outriggers 52 and connecting net 8, a huge, flexible adsorption support surface can be formed after leveling. The connecting net 8 covers the bottom material below, increasing frictional resistance and vacuum adsorption effect, enhancing the ability to resist water flow and overturning, and ensuring the continuity and stability of long-term monitoring tasks. The acrylic sealing cover 21 provides protection while offering a good field of view for the monitoring equipment 3; the top hook 22 and the stabilizing frame optimize the ease of deployment and the overall structural strength, respectively. These designs enable the device to integrate multiple functions such as protection, observation, stabilization, and deployment within a limited space, resulting in higher overall reliability.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
