Description

Technical Field

[0001] This utility model relates to the field of mounting bracket design, and in particular to an auxiliary mounting bracket for marine surveying equipment. Background Technology

[0002] Mounting brackets are structural components used to support and secure equipment or cables. They are typically made of metal (such as angle steel) or composite materials (such as fiberglass) and must meet requirements for strength, corrosion resistance, and insulation. They are widely used in cable laying, power systems, and engineering equipment installation. Auxiliary mounting brackets for marine surveying equipment are installation devices specifically designed for marine environments.

[0003] However, conventional supports lack an active leveling mechanism. When the hull experiences rolling or tilting, the installation platform is prone to angular displacement due to wave impacts. This causes the detection axes of precision equipment such as sonar and depth sounders to deviate from the preset azimuth angle, resulting in an increased error rate in survey data acquisition. Especially during multibeam bathymetric surveys, such deviations can cause misalignment of adjacent scan strips, requiring significant post-processing time for correction. Furthermore, the installation plane of traditional supports forms a fixed angle with the base, making it impossible to quickly switch between horizontal placement (deck installation mode) and vertical hoisting (overboard operation mode) according to operational needs. When performing tasks such as seabed geological sampling that require equipment to be suspended, operators must disassemble and reassemble the support structure, a time-consuming process that limits the effective utilization of the oceanographic research vessel's operational window.

[0004] Therefore, there is an urgent need to propose an auxiliary mounting bracket for marine surveying equipment. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an auxiliary mounting bracket for marine surveying equipment.

[0006] The technical implementation scheme of this utility model is as follows: an auxiliary installation bracket for marine surveying equipment, comprising a support plate, a flap plate, a support base, a rotating shaft, a limiting plate, an electric push rod, an electric gripper, a worm gear, a limiting plate, a worm, a rocker arm, and a drive assembly. The top of the support plate is connected to the flap plate, and the top of the flap plate is provided with a support base. The rotating shaft is connected inside the support base. The bottom of the flap plate is rotatably connected to the limiting plate, and the bottom of the limiting plate is equipped with an electric push rod. An electric gripper is connected to the telescopic end of the electric push rod. One end of the rotating shaft is connected to the worm gear. Symmetrical limiting plates are provided on one side of the flap plate corresponding to the worm gear. A worm is rotatably connected between the two limiting plates. The worm meshes with the worm gear above. Both ends of the worm are connected to rockers. A drive assembly is provided at the bottom of the limiting plate.

[0007] Preferably, the lower part of the joystick extends vertically, and one end of the vertical extension is provided with a handle.

[0008] Preferably, it also includes an anti-slip sleeve, with the grip at the bottom of the joystick having an anti-slip sleeve attached to the outside.

[0009] Preferably, it also includes a toothed disc, a servo motor, and gears. The toothed disc is connected to the lower part of the limiting disc, and a servo motor is installed on one side of the bottom of the flip plate. A gear is connected to the output shaft of the servo motor, and the gear meshes with the adjacent toothed disc.

[0010] Preferably, it also includes a protective disc, which limits the external rotation of the device.

[0011] Preferably, a protective shell is also included, with the upper side of the support plate connected to the protective shell, which covers the outside of the worm gear and worm.

[0012] The beneficial effects of this utility model are as follows: 1. By using the meshing transmission of the worm gear and worm wheel in conjunction with the damping constraint of the limiting plate, the mechanical self-locking function of adjusting the horizontal tilt angle of the support seat is realized. Even under the condition of hull turbulence, the attitude of the surveying equipment installation platform can still be kept stable, solving the problem of angle displacement caused by the impact of waves in traditional supports; the support plate and the flip plate are connected by a hinge, and the installation platform can be flipped and unfolded in conjunction with the rotating shaft drive, which not only meets the requirements of deck plane installation, but can also be quickly converted into a vertical hoisting mode, breaking through the limitation of traditional fixed supports that cannot be adapted to multiple deployment scenarios.

[0013] 2. The gripper is driven by an electric push rod to extend and retract radially along the limiting plate. Its front end adaptive curved surface can match the outer shape of different models of surveying equipment. The clamping force is fed back in real time by a pressure sensor, avoiding the risk of equipment falling off due to deformation of the equipment shell or insufficient clamping force caused by manual locking.

[0014] 3. Through a closed-loop control system consisting of a gear plate and a servo motor gear, the gear transmission automatically corrects the limit plate rotation angle error, keeping the equipment installation plane level error within a suitable range, thereby improving the accuracy of deep-water mapping data acquisition.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example: An auxiliary mounting bracket for marine surveying equipment, such as... Figures 1-6 As shown, the device includes a support plate 1, a flip plate 2, a support base 3, a rotating shaft 4, a limiting plate 5, an electric push rod 6, an electric gripper 7, a worm gear 8, a limiting plate 9, a worm 10, a rocker arm 11, and a drive assembly. The support plate 1 serves as the base of the mounting bracket, bearing the load and providing stability to the overall structure. The top of the support plate 1 is connected to the flip plate 2, which acts as the main support for the equipment installation platform, enabling switching between horizontal and vertical installation modes. The top of the flip plate 2 is equipped with a support base 3, inside which a rotating shaft 4 is connected. The bottom of the flip plate 2 is rotatably connected to a limiting plate 5, and an electric push rod is installed at the bottom of the limiting plate 5. The electric push rod 6 has an electric gripper 7 connected to its telescopic end. The electric gripper 7 adaptively clamps surveying equipment of different shapes. The electric push rod 6 drives the electric gripper 7 to extend and retract radially along the limiting plate 5. One end of the rotating shaft 4 is connected to a worm gear 8. The flip plate 2 is provided with symmetrical limiting plates 9 on one side corresponding to the worm gear 8. The two limiting plates 9 are rotatably connected to a worm 10. The worm 10 rotates and meshes with the worm gear 8 above. Both ends of the worm 10 are connected to rockers 11. The lower part of the rocker 11 extends vertically, and one end of the vertical extension is provided with a handle. The lower part of the limiting plate 5 is provided with a drive assembly.

[0024] like Figure 1 and Figure 4 As shown, it also includes an anti-slip sleeve 17. The handle at the bottom of the joystick 11 is connected to the outside of the anti-slip sleeve 17 to increase the friction of the joystick 11 handle and prevent slippage caused by seawater or oil.

[0025] like Figure 5 and Figure 6As shown, it also includes a gear disk 12, a servo motor 13, and a gear 14. The gear disk 12 is connected to the lower part of the limiting disk 5. The servo motor 13 is installed on one side of the bottom of the flip plate 2. The servo motor 13 provides the driving power for the rotation of the gear disk 12. The gear 14 is connected to the output shaft of the servo motor 13. The gear 14 meshes with the adjacent gear disk 12. The meshing of the gear 14 and the gear disk 12 forms a closed-loop control transmission chain to achieve high-precision angle correction.

[0026] like Figures 1-4 As shown, it also includes a protective disc 15, which limits the external rotation of the protective disc 15.

[0027] like Figure 2 As shown, it also includes a protective shell 16. The protective shell 16 is connected to one side of the upper part of the support plate 1. The protective shell 16 covers the outside of the worm wheel 8 and the worm 10, thereby sealing the transmission cavity of the worm wheel 8 and the worm 10.

[0028] In use, the operator first fixes the support plate 1 to the ship's deck or underwater base, then activates the drive assembly to slowly extend the electric push rod 6, pushing the limit plate 5 to unfold to a horizontal position along the bottom rotation axis of the flip plate 2. At this time, the operator shakes the rocker arms 11 extending from both ends of the worm gear 10 by gripping the handle. The worm gear 10 and the worm wheel 8 form a meshing transmission, driving the rotating shaft 4 to drive the support base 3 and the upper flip plate 2 to rotate synchronously, realizing the horizontal tilt angle adjustment of the equipment installation platform. During the rotation of the worm gear 10, the limit plate 9 suppresses the vibration caused by asymmetrical loads through an internal damper, ensuring the stability of the angle adjustment. When the surveying equipment is hoisted to the support base 3, the electric gripper 7 extends radially along the limit plate 5 under the drive of the electric push rod 6. The adaptive curved surface of the gripper front end fits against the equipment shell, and then is adjusted by external sensors. The clamping force is adjusted to prevent the equipment from slipping. At this time, the servo motor 13 starts and meshes with the gear plate 12 through the output shaft gear 14, driving the limit plate 5 to rotate slightly, eliminating the installation platform offset error caused by the hull swaying. The protective plate 15 rotates synchronously with the limit plate 5, and its edge can divert the impact water flow, reducing the erosion of precision transmission components by ocean turbulence. When conducting deep-water mapping, the protective shell 16 prevents seawater from seeping into the transmission cavity of the worm gear 8 and worm 10. When it is necessary to adjust the observation angle of the equipment, the operator shakes the rocker arm 11 again to drive the worm 10, and the worm gear 8 drives the rotating shaft 4 to rotate precisely, and the equipment on the support base 3 changes its pitch angle accordingly. After the equipment installation is completed, the electric push rod 6 retracts and pulls the limit plate 5 to reset, and the gear plate 12 disengages from the servo motor 13 and gear 14 to save energy.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
