Description

Technical Field

[0001] This utility model relates to the field of marine surveying equipment technology, specifically a fixed bracket for marine surveying equipment. Background Technology

[0002] Multibeam sonar is an advanced marine mapping and detection device. It transmits and receives multiple sound beams to achieve high-precision, full-coverage measurement of the underwater environment. It can quickly acquire large-area seabed topography, water depth data, and target information. In order to ensure the stability of the equipment during operation, a fixed support is required for multibeam sonar.

[0003] A Chinese patent with authorization announcement number CN111976889A discloses a mounting frame for a marine surveying device, including a mounting mechanism. The mounting mechanism extends out of the hull of the surveying vessel. The mounting mechanism includes a mounting shaft mounted on the main frame, a swing plate arranged radially along the mounting shaft and rotatably connected to the mounting shaft, connecting plates fixed at both ends of the swing plate, and a mounting plate arranged between the two connecting plates for mounting the surveying device. Rotating shafts are fixed at both ends of the mounting plate, and the rotating shafts are rotatably connected to the two connecting plates respectively. A counterweight is provided below the mounting plate, and the center of gravity of the counterweight and the intersection point of the axis of the mounting shaft and the axis of the rotating shaft are located on the same vertical line. This application has the effect of reducing the impact of the surveying vessel's swaying on the verticality of the surveying device.

[0004] However, the aforementioned mounting bracket still has some problems. In practical applications, ships sway due to waves during navigation. The existing fixed bracket cannot adjust the angle in real time to counteract the ship's movement. The transducer plane of the multibeam sonar will deviate from the horizontal plane, resulting in a deviation in the angle of the emitted sound beam and reducing the accuracy of the surveying equipment. Therefore, a fixed bracket for marine surveying equipment is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a fixed bracket for marine surveying equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A fixed support for marine surveying equipment, comprising a ship, wherein a fixed rod is installed inside the ship, a mounting plate is installed at the top of the fixed rod, and an angle adjustment component is installed directly below the mounting plate. The angle adjustment component comprises a fixed frame, with rotating shafts rotatably mounted inside both sides of the fixed frame, and a mounting frame fixedly connected between the two sides of the rotating shafts. A connecting cavity is connected to one side of the fixed frame, and a servo motor is installed inside one side of the connecting cavity. The output end of the servo motor... A connecting shaft is installed, and a worm gear is mounted on the outer side of the connecting shaft. One end of one of the rotating shafts passes through the interior of the connecting cavity and is equipped with a worm wheel. The worm wheel meshes with the worm. A servo motor drives the connecting shaft and the worm to rotate, and the worm then meshes with the worm wheel at one end of one of the rotating shafts, realizing the angle adjustment of the marine surveying equipment. The worm gear transmission method has self-locking properties, which can ensure the stability after angle adjustment. The maximum angle adjustment range is 60 degrees, which allows the marine surveying equipment to flexibly adjust the angle according to different marine environments and measurement needs, thereby effectively improving the measurement accuracy.

[0007] Preferably, a drive motor is mounted on the top side of the mounting plate, and a lead screw is mounted on the output end of the drive motor. A support plate is mounted on one end of the top side of the vessel. The lead screw is rotatably mounted inside the support plate. A guide rod is fixed between the support plate and the mounting plate. A movable plate is movably mounted on the outer side of the guide rod and the lead screw in cooperation. The fixed frame is mounted on the bottom side of the movable plate. When the drive motor starts, the lead screw rotates. Under the guidance of the guide rod, the movable plate can perform stable lifting and lowering movements along the lead screw and the guide rod, thereby driving the fixed frame and marine surveying equipment to achieve lifting and lowering operations. The height of the marine surveying equipment can be quickly adjusted according to actual measurement needs to meet marine surveying work at different depths.

[0008] Preferably, threaded rods are threadedly connected to the interior of both sides of the mounting frame, and a handle is installed at one end of each threaded rod. Two sliding rods are symmetrically and slidably installed on both sides of the mounting frame, and a fixing plate is installed at one end of each sliding rod. One end of each threaded rod is rotatably installed inside one side of the fixing plate. By rotating the handle, the threaded rods can be rotated, thereby pushing the fixing plate to slide along the sliding rods, thus clamping and fixing the marine surveying equipment. This allows for adjustment according to marine surveying equipment of different sizes, ensuring the stability of the equipment during surveying operations, avoiding the impact of equipment shaking on measurement accuracy, and improving the reliability and accuracy of surveying work.

[0009] Preferably, a limit ring is installed on one side of the mounting frame. The limit ring has a screw hole inside, through which the threaded rod is movably installed. A locking screw is rotatably installed inside the limit ring. One end of the locking screw abuts against the threaded rod. After the position of the fixing plate is adjusted and the marine surveying equipment is fixed by the threaded rod, the locking screw is rotated so that one end abuts against the threaded rod, which can effectively lock the threaded rod and prevent it from loosening due to vibration or other reasons during equipment operation, thereby avoiding instability of the surveying equipment.

[0010] Preferably, the fixing clamp is L-shaped, and the inner wall of the fixing clamp is equipped with rubber anti-slip pads. The rubber anti-slip pads have good elasticity and friction, which can effectively increase the friction between the fixing clamp and the marine surveying equipment, prevent the equipment from sliding during the fixing process, and further improve the firmness of the equipment fixing.

[0011] Preferably, the vessel is equipped with an engine inside, a support rod is installed on the outside of the fixed rod, and a control panel is installed at one end of the support rod. The control panel is electrically connected to the electrical components inside the device. The control panel is used to operate and control the electrical components inside the device. The engine provides power support for the entire device. The operator of the control panel can conveniently start or stop the drive motors and servo motors, and adjust the angle and height of the device from one position.

[0012] The advantages of this utility model are:

[0013] 1. In this utility model, the servo motor drives the connecting shaft to rotate, causing the outer worm to rotate. The worm meshes with the worm wheel, driving the worm wheel to rotate. The rotation of the worm wheel drives the rotating shaft to rotate within the fixed frame. Because the rotating shaft is fixedly connected to the mounting frame, the angle of the mounting frame and the surveying equipment can be adjusted. The self-locking property of the worm gear transmission ensures that the angle of the mounting frame and equipment remains stable after the servo motor stops running, preventing deviation during measurement. This structure can be adjusted up to 60 degrees, allowing for flexible adjustment according to the marine environment and measurement needs, effectively improving measurement accuracy.

[0014] 2. This utility model places the marine surveying equipment between two fixed clamps in the mounting frame. By rotating the handle, the threaded rod rotates on both sides of the mounting frame, pushing the fixed clamps to slide symmetrically along the slide bar until the equipment is clamped. At this time, the rubber anti-slip pads on the inner wall of the fixed clamps prevent the equipment from sliding due to elasticity and friction. After the equipment is fixed, the locking screw in the limiting ring is rotated to press against the threaded rod, effectively locking the position and preventing the threaded rod from loosening due to vibration. This ensures that the surveying equipment is stably fixed and meets the needs of marine surveying operations. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5As shown, a fixed support for marine surveying equipment includes a vessel 1. A fixed rod 2 is installed inside the vessel 1, and an mounting plate 3 is installed at the top of the fixed rod 2. An angle adjustment component is installed directly below the mounting plate 3. The angle adjustment component includes a fixed frame 4. Rotating shafts 5 are rotatably installed inside both sides of the fixed frame 4. A mounting frame 6 is fixed between the two sides of the rotating shafts 5. A connecting cavity 7 is connected to one side of the fixed frame 4. A servo motor 8 is installed inside one side of the connecting cavity 7. A connecting shaft 9 is installed at the output end of the servo motor 8. A worm gear 10 is installed on the outside of the connecting shaft 9. One end of one of the rotating shafts 5 passes through the interior of the connecting cavity 7 and is equipped with a worm wheel 11. The worm wheel 11 meshes with the worm gear 10.

[0024] A drive motor 12 is installed on the top side of the mounting plate 3, and a lead screw 13 is installed at the output end of the drive motor 12. A support plate 14 is installed at one end of the top side of the ship 1. The lead screw 13 is rotatably installed inside the support plate 14. A guide rod 15 is fixedly connected between the support plate 14 and the mounting plate 3. A movable plate 16 is movably installed on the outer side of the guide rod 15 and the lead screw 13 in cooperation. The fixing frame 4 is installed on the bottom side of the movable plate 16.

[0025] The vessel 1 is internally equipped with an engine 23. A support rod 24 is mounted on the outside of the fixed rod 2. A control panel 25 is mounted on one end of the support rod 24. The control panel 25 is electrically connected to the electrical components inside the device and is used to control the operation of the electrical components inside the device. During operation, in practical applications, the vessel 1 sways due to waves during navigation. In the existing technology, the fixed bracket cannot adjust the angle in real time to counteract the hull movement. The transducer plane of the multibeam sonar will deviate from the horizontal plane, resulting in a deviation in the angle of the emitted sound beam, which reduces the accuracy of the surveying equipment. When it is necessary to adjust the angle of the marine surveying equipment, the operator starts the servo motor 8 through the control panel 25. The servo motor 8 drives the connecting shaft 9 to rotate, and the worm gear 10 on the outside of the connecting shaft 9 rotates accordingly. Since the worm gear 10 and the worm wheel 11 mesh with each other, the rotation of the worm gear 10... The worm gear 11 is driven to rotate, which in turn drives the rotating shaft 5 to rotate inside both sides of the fixed frame 4. The rotating shaft 5 is fixed to the mounting frame 6, thereby realizing the angle adjustment of the mounting frame 6 and the marine surveying equipment fixed on it. The worm gear 11 and worm 10 transmission has self-locking property. When the angle is adjusted to the required position, the servo motor 8 stops running. Under the self-locking action, the angle of the mounting frame 6 and the surveying equipment is stably maintained, ensuring that the angle will not deviate during the measurement process. Moreover, this structure can achieve a maximum angle adjustment of 60 degrees, which can meet the angle adjustment under different marine environments and measurement needs, and improve the measurement accuracy. It should be noted that the center point of the hull in the vessel 1 will be equipped with an inclination sensor. The servo motor 8 adjusts the angle of the marine surveying equipment by cooperating with the inclination sensor. The specific model of the inclination sensor is SiliconSensing-CRS03A.

[0026] Based on actual measurement needs, the operator starts the drive motor 12 through the control panel 25. The lead screw 13 at the output end of the drive motor 12 starts to rotate. During the rotation of the lead screw 13, the guide rod 15 plays a guiding role, so that the movable plate 16 can move up and down stably along the lead screw 13 and the guide rod 15. Because the fixed frame 4 is installed on the bottom side of the movable plate 16, the lifting and lowering of the movable plate 16 drives the fixed frame 4 and the marine surveying equipment fixed on the fixed frame 4 to achieve lifting and lowering operations. The height of the marine surveying equipment can be quickly adjusted to meet the needs of marine surveying work at different depths.

[0027] The fixed bracket is powered by an engine 23, which is a Cummins QSB series engine.

[0028] Please see Figure 1-5As shown, threaded rods 17 are threadedly connected to both sides of the mounting frame 6. A handle 18 is installed at one end of each threaded rod 17. Two sliding rods 19 are symmetrically slidably installed on both sides of the mounting frame 6. A fixing plate 20 is installed at one end of each sliding rod 19. One end of each threaded rod 17 is rotatably installed inside one side of the fixing plate 20.

[0029] Each side of the mounting frame 6 is equipped with a limiting ring 21. The limiting ring 21 has a screw hole inside. The threaded rod 17 is movably inserted through the screw hole. A locking screw 22 is rotatably installed inside the limiting ring 21. One end of the locking screw 22 abuts against the threaded rod 17.

[0030] The fixing clamp 20 is L-shaped, and the inner wall of each fixing clamp 20 is equipped with rubber anti-slip pads. During operation, the multibeam sonar in the marine surveying equipment is affected by wave impact and ship vibration during the navigation of the ship 1. The positional deviation of the sonar equipment will directly affect the angle of its transmitted and received sound waves. Insecure equipment fixation will lead to measurement data deviation. The marine surveying equipment is placed between the two fixing clamps 20 in the mounting frame 6. The handle 18 is turned, which drives the threaded rod 17 to rotate inside the mounting frame 6 on both sides. Therefore, the movement of the threaded rod 17 will push the fixing clamp 20 along the slide rod 19. The mounting frame 6 slides symmetrically on both sides until the two fixing plates 20 clamp the marine surveying equipment. At this time, the rubber anti-slip pads on the inner wall of the fixing plates 20 come into contact with the equipment. The good elasticity and friction of the rubber anti-slip pads increase the friction between the equipment and prevent the equipment from sliding during the fixing process. After the fixing plates 20 are adjusted and the equipment is fixed, the locking screw 22 inside the limiting ring 21 is rotated so that one end of it abuts against the threaded rod 17, thereby effectively locking the threaded rod 17 and preventing it from loosening due to vibration or other reasons during the operation of the equipment, thus ensuring the stable fixing of the surveying equipment.

[0031] Working principle: The marine surveying equipment is placed between two fixed clamps 20 inside the mounting frame 6. The handle 18 is turned, which drives the threaded rod 17 to rotate inside both sides of the mounting frame 6. Therefore, the movement of the threaded rod 17 will push the fixed clamps 20 to slide symmetrically along the slide rod 19 on both sides of the mounting frame 6 until the two fixed clamps 20 clamp the marine surveying equipment. At this time, the rubber anti-slip pad on the inner wall of the fixed clamp 20 contacts the equipment. The good elasticity and friction of the rubber anti-slip pad increases the friction between the equipment and the equipment, preventing the equipment from sliding during the fixing process. After the fixed clamps 20 are adjusted and the equipment is fixed, the locking screw 22 inside the limiting ring 21 is rotated so that one end of it abuts against the threaded rod 17, thereby effectively locking the threaded rod 17 and preventing it from loosening due to vibration or other reasons during the operation of the equipment, ensuring the stable fixing of the surveying equipment.

[0032] When the angle of the marine surveying equipment needs to be adjusted, the operator starts the servo motor 8 via the control panel 25. The servo motor 8 drives the connecting shaft 9 to rotate, and the worm gear 10 on the outside of the connecting shaft 9 rotates accordingly. Since the worm gear 10 and the worm wheel 11 mesh with each other, the rotation of the worm gear 10 drives the worm wheel 11 to rotate. The rotation of the worm wheel 11 drives the rotating shaft 5 to rotate inside both sides of the fixed frame 4. The rotating shaft 5 is fixed to the mounting frame 6, thereby realizing the angle adjustment of the mounting frame 6 and the marine surveying equipment fixed on it. The worm gear 11 and worm wheel 10 transmission has self-locking property. When the angle is adjusted to the required value... After positioning, the servo motor 8 stops running. Under the self-locking action, the angle of the mounting frame 6 and the surveying equipment is stably maintained, ensuring that the angle will not shift during the measurement process. Moreover, this structure can achieve a maximum angle adjustment of 60 degrees to meet the angle adjustment requirements under different marine environments and measurement needs, thereby improving measurement accuracy. It should be noted that the center point of the hull in the vessel 1 is equipped with an inclination sensor. The servo motor 8 adjusts the angle of the marine surveying equipment by cooperating with the inclination sensor. The specific model of the inclination sensor is SiliconSensing-CRS03A.

[0033] Based on actual measurement needs, the operator starts the drive motor 12 through the control panel 25. The lead screw 13 at the output end of the drive motor 12 starts to rotate. During the rotation of the lead screw 13, the guide rod 15 plays a guiding role, so that the movable plate 16 can move up and down stably along the lead screw 13 and the guide rod 15. Because the fixed frame 4 is installed on the bottom side of the movable plate 16, the lifting and lowering of the movable plate 16 drives the fixed frame 4 and the marine surveying equipment fixed on the fixed frame 4 to achieve lifting and lowering operations. The height of the marine surveying equipment can be quickly adjusted to meet the needs of marine surveying work at different depths.

[0034] The fixed bracket is powered by an engine 23, which is a Cummins QSB series engine.
