Description

Technical Field

[0001] This utility model relates to the field of underwater measurement technology, and in particular to a support for a mobile multibeam underwater measurement device. Background Technology

[0002] A multibeam underwater measurement device is a high-precision acoustic measurement device used for underwater topography, landform and target detection. It achieves efficient and full-coverage measurement of underwater areas by simultaneously emitting multiple sound beams (usually dozens to hundreds) and receiving reflected signals.

[0003] Existing multibeam underwater measurement devices are typically fixed by binding the instrument pole with steel cables. While this method is simple, it has obvious drawbacks. Due to the lack of specially designed adapters and fixing brackets, the positioning of the instrument pole relies entirely on the restraint of the steel cables, resulting in insufficient equipment stability, limited adjustment angles, and low operational flexibility during the measurement process. It is particularly difficult to achieve accurate measurements in complex underwater environments, affecting data acquisition quality and work efficiency.

[0004] Therefore, in view of the problem that existing multibeam underwater measurement devices typically use steel cables to bind the instrument pole and rely on the steel cables for positioning, lacking suitable fixed supports and having low flexibility during measurement, there is an urgent need to design a new type of mobile multibeam underwater measurement device support. Utility Model Content

[0005] To overcome the problem that existing multibeam underwater measurement devices typically use steel cables to bind the instrument pole and rely on the steel cables for positioning, lacking suitable fixed supports and thus having low flexibility during measurement.

[0006] The technical solution of this utility model is as follows: a mobile multibeam underwater measurement device support, including a mounting bracket, an adjustment component, a connecting shaft, a positioning roller, a ball seat, fixing bolts, a steel ball, and a placement frame. There are two mounting brackets arranged symmetrically on the left and right sides. An adjustment component for adjusting the distance is arranged between the two mounting brackets. Two connecting shafts are installed at the upper and lower ends of the interior of the two mounting brackets. Two positioning rollers are rotatably connected around the connecting shafts. A ball seat is arranged at the top center of the left mounting bracket. Six fixing bolts are arranged in a circular pattern near the upper edge of the ball seat. The ball seat is fixed to the left mounting bracket by the fixing bolts. A steel ball is movably connected inside the ball seat. A placement frame is installed on the top of the steel ball.

[0007] Preferably, by setting an adjustment component, the distance between the two mounting supports can be adjusted to adapt to the railing of the hull. After the mounting supports are positioned, the positioning rollers on both sides are in contact with the sides of the railing, allowing the mounting supports to slide along the railing. The instrument rod is mounted inside the placement frame, and the steel ball can rotate inside the ball seat, allowing the placement frame to drive the instrument rod to make multi-angle adjustments, improving the flexibility during measurement. This solves the problem that existing multibeam underwater measurement devices usually use steel cables to bind the instrument rod and rely on the steel cables to position the instrument rod, lacking a suitable fixed support and having low flexibility during measurement.

[0008] Preferably, the adjustment assembly includes a lead screw and a knob; the lead screw is rotatably connected to the upper right side of the right mounting bracket, the left end of the lead screw is rotatably connected to the left mounting bracket, and the right end of the lead screw is provided with a knob.

[0009] Preferably, the adjustment assembly also includes a limit rod and a limit piece; the right surface of the left mounting bracket is equipped with limit rods at both ends of the lead screw, and the right end of the limit rod passes through the right mounting bracket and connects to the limit piece.

[0010] Preferably, the bottom of the opposite surfaces of the two mounting supports are provided with mounting grooves, and the front and rear ends of the opposite surfaces of the two mounting grooves are rotatably connected to damping shafts.

[0011] Preferably, the damping shaft is fixed with positioning rods around its perimeter, and weight reduction grooves are opened through the right side of each of the four positioning rods.

[0012] Preferably, a screw is installed at the bottom center of the placement rack, and a positioning screw hole is opened at the top center of the steel ball, with the screw matching the positioning screw hole.

[0013] Preferably, the adjustment component also includes anti-slip texture; the knob is machined with anti-slip texture all around, and the positioning roller is conical.

[0014] The beneficial effects of this utility model are:

[0015] 1. The adjustable mounting bracket achieves the desired spacing with the ship's railing. With the help of positioning rollers, the mounting bracket can slide smoothly along the railing track. The instrument rod is assembled in the inner cavity of the placement frame. Through the rotation mechanism of the ball seat and steel ball, the placement frame can drive the instrument rod to achieve multi-degree-of-freedom azimuth adjustment, which significantly improves the mobility and adaptability of the measurement operation. This allows the measurement equipment to quickly adapt to complex working environments and greatly enhances the coverage and accuracy of the measurement angles. The overall structure combines rigidity and flexibility, effectively overcoming the interference of ship swaying. This results in a breakthrough improvement in the mobility and adaptability of underwater measurement operations, while reducing the labor intensity of manual adjustments.

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

[0023] Please see Figures 1-5This utility model provides an embodiment of a mobile multibeam underwater measurement device support, comprising a mounting base 1, an adjustment assembly, a connecting shaft 3, positioning rollers 4, ball seats 5, fixing bolts 6, steel balls 7, and a placement frame 8. Two mounting bases 1 are symmetrically arranged on the left and right sides, and an adjustment assembly for adjusting the distance is provided between the two mounting bases 1. Two connecting shafts 3 are installed at the upper and lower ends of each of the two mounting bases 1, and two positioning rollers 4 are rotatably connected to the circumference of the connecting shafts 3. A ball seat 5 is located at the top center of the left mounting base 1, and six circumferentially distributed fixing bolts 6 are located near the upper edge of the ball seat 5. The ball seat 5 is fixed to the mounting bracket 1 on the left side by fixing bolts 6. The ball seat 5 has a steel ball 7 movably connected inside, and the top of the steel ball 7 is equipped with a placement frame 8. By setting an adjustment component, the distance between the two mounting brackets 1 can be flexibly adjusted to adapt to different widths of the ship's railing. After the mounting bracket 1 is positioned and fixed, the positioning rollers 4 on both sides will be close to the sides of the railing to ensure that the mounting bracket 1 can slide smoothly along the railing. The instrument rod is installed in the placement frame 8, and the rotation function is realized through the cooperation of the steel ball 7 and the ball seat 5, so that the placement frame 8 can drive the instrument rod to make multi-angle orientation adjustments, which significantly improves the flexibility and adaptability of the measurement operation.

[0024] Please see Figures 1-4 In this embodiment, the adjustment assembly includes a lead screw 21 and a knob 22; the lead screw 21 is rotatably connected to the upper right side of the right mounting bracket 1, the left end of the lead screw 21 is rotatably connected to the left mounting bracket 1, and the right end of the lead screw 21 is provided with a knob 22. By providing the knob 22, rotating the knob 22 can drive the lead screw 21 to rotate. When the lead screw 21 rotates, it can drive the right movable seat with its threaded engagement to move left and right, so that the positioning rollers 4 on both sides can fit against the ship's railing. The adjustment assembly also includes a limit rod 24 and a limit piece 25; the left mounting bracket... Limiting rods 24 are installed on both the front and rear ends of the lead screw 21 on the right surface of the seat 1. The right end of the limiting rod 24 passes through the right mounting bracket 1 and connects to the limiting piece 25. By setting the limiting rod 24 and the limiting piece 25, the right mounting bracket 1 can be positioned to avoid the problem of the lead screw 21 driving the right mounting bracket 1 to rotate synchronously when rotating, which would reduce the transmission efficiency. The bottom of the opposite surfaces of the two mounting brackets 1 are provided with mounting grooves 9. The front and rear ends of the opposite surfaces of the two mounting grooves 9 are rotatably connected to the damping shaft 10. The mounting grooves 9 are used to install the damping shaft 10.

[0025] Please see Figures 2-5In this embodiment, positioning rods 11 are fixed around the damping shaft 10. Weight reduction grooves 12 are provided through the right side of each of the four positioning rods 11. By setting the positioning rods 11 and cooperating with the damping shaft 10, the positioning rods 11 can rotate downward to a vertical angle, thereby fitting against the fence and achieving the purpose of auxiliary positioning. A screw 13 is installed at the bottom center of the placement frame 8, and a positioning screw hole 14 is provided at the top center of the steel ball 7. The screw 13 and the positioning screw hole 14 are compatible. By setting the screw 13 and the screw hole, it is easy to quickly connect and position the placement frame 8 and the steel ball 7. The adjustment component also includes anti-slip texture 23. The knob 22 is machined with anti-slip texture 23 around its body. The positioning roller 4 is conical. By setting the anti-slip texture 23, the friction of the knob 22 surface can be improved. The conical positioning roller 4 has the function of self-correction and self-centering, which can improve the stability of the two mounting supports 1 when moving.

[0026] During operation, the ball seat 5 is installed on the top of the left mounting bracket 1 using the fixing bolt 6. Then, the placement frame 8 is installed by the cooperation of the screw 13 and the positioning screw hole 14, and the entire device is mounted on the upper part of the ship's railing. The knob 22 is turned to drive the lead screw 21 to rotate, thereby adjusting the distance between the two mounting brackets 1 so that the positioning roller 4 is in contact with the side of the railing. Then, the four positioning rods 11 are rotated downwards by 90 degrees to assist in positioning the entire device and prevent it from tipping over. During measurement, the instrument rod can achieve multi-angle rotation while moving laterally through the action of the positioning roller 4 and the ball seat 5.

[0027] Through the above steps, by setting the adjustment component, the distance between the two mounting supports 1 can be adjusted to adapt to different widths of the ship's railing. After positioning, the positioning rollers 4 on both sides fit tightly with the railing, ensuring that the mounting supports 1 can slide stably along the railing. The instrument rod is mounted inside the placement frame 8. Through the rotational cooperation of the steel ball 7 and the ball seat 5, the multi-angle adjustment function is realized, so that the placement frame 8 can drive the instrument rod to flexibly adjust its orientation, thereby improving the adaptability and ease of operation during measurement. This solves the problem that existing multibeam underwater measurement devices usually use steel cables to bind the instrument rod and rely on the steel cables to position the instrument rod, lacking suitable fixed supports and having low flexibility during measurement.
