Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shallow seismic profiling measurement technology, and in particular relates to a measuring device for a shallow seismic profiling instrument. Background Technology
[0002] A seismic profiler is an instrument that uses sound waves to probe the profile structure of shallow seabed strata, providing a cross-sectional view of the bottom strata of oceans, rivers, and lakes. In use, the seismic profiler is mounted on a ship via a rod-shaped measuring device; one end of the measuring device is attached to the hull, and the other end is fitted with the seismic profiler, which must extend underwater. In existing technology, the measuring rod of a seismic profiler can only move the profiler longitudinally, resulting in a limited functionality. Furthermore, if the profiler is close to the hull or propeller blades in the water, the forces exerted by the hull or propeller blades on the water during movement can easily be transmitted to the seismic profiler and the longitudinally mounted measuring rod, thus affecting the installation stability of both the measuring rod and the profiler. Utility Model Content
[0003] In view of this, the present invention aims to overcome the shortcomings of the above-mentioned problems in the prior art and proposes a measuring device for a shallow seismic profiler.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A measuring device for a shallow seismic profiler includes a mounting base, a first connecting frame fixed to the front side of the mounting base, a first connecting seat movable along the length of the first connecting frame in the first connecting frame, a second connecting frame fixed to the bottom of the first connecting frame and inclined downward from back to front, a second connecting seat movable along the length of the second connecting frame in the second connecting frame, and a first mounting component fixed to the rear side of the second connecting seat.
[0006] Furthermore, the mounting base is a clamp structure and includes two semi-circular clamping plates that are joined together. Each clamping plate has a mounting plate integrally formed with the corresponding clamping plate on both sides, and the two mounting plates on the same side are joined together and fixed together by U-bolts and nuts.
[0007] Furthermore, a first through groove is provided on the upper side of the first connecting frame along the length direction of the first connecting frame. A first screw rod is connected in the first through groove along the length direction of the first connecting frame. A first motor is fixedly connected to the front end of the first connecting frame. The output shaft of the first motor is fixedly connected to the first screw rod. The left and right side walls of the upper part of the first connecting seat are in contact with the inner wall of the first through groove and are screwed together with the first screw rod.
[0008] Furthermore, the bottom of the first connecting seat has a connecting plate extending beyond the left side of the first connecting frame, and the connecting plate is inclined downward from front to back. The second connecting frame is fixed to the front side of the front wall of the connecting plate. The front side of the second connecting frame has a second through groove along the length of the second connecting frame. A second screw along the length of the second connecting frame is connected in the second through groove. A second motor is fixed to the rear side of the connecting plate, and the output shaft of the second motor is fixed together with the second screw. The upper left and right side walls of the second connecting seat are in contact with the inner wall of the second through groove and are screwed together with the second screw.
[0009] Furthermore, a fixed shaft is fixedly connected to the right side of the first connecting frame near the mounting base, a pull rope is wound around the fixed shaft, and the other end of the pull rope is connected to a second mounting component.
[0010] Furthermore, both the first and second mounting components are clamp structures, and a lifting lug is fixed to the second mounting component, with the pull rope attached to the lifting lug.
[0011] Furthermore, multiple evenly distributed connecting blocks are fixed to the right end of the fixed shaft along the circumferential surface, and an auxiliary ring is fixed together between the ends of the multiple connecting blocks.
[0012] Compared with the prior art, this utility model has the following advantages:
[0013] When using the shallow seismic profiler measuring device described in this utility model, the shallow seismic profiler is fixed to the first mounting component, and the mounting base is fixed to the railing of the ship's side, so that the first connecting frame extends out of the hull. Then, the first connecting base is moved forward, driving the second connecting frame forward and downward, thus extending the shallow seismic profiler into the water. This device adjusts the position of the shallow seismic profiler in the water by adjusting the positions of the first and second connecting bases. Furthermore, by tilting the second connecting frame downward from back to front, the shallow seismic profiler can move forward to a farther position, thereby increasing the distance between it and the hull. This reduces the impact of the force exerted by the hull and the propeller blades on the water flow on the shallow seismic profiler and the second connecting frame. Attached Figure Description

[0024] Mounting base 1 is a clamp structure, and includes two semi-circular clamping plates that are joined together. Each clamping plate has a mounting plate integrally formed with the corresponding clamping plate on both sides, and the two mounting plates on the same side are joined together and fixed together by U-bolts and nuts.
[0025] A first through groove 201 is provided on the upper side of the first connecting frame 2 along its length. A first screw 3, also along the length of the first connecting frame 2, is connected within the first through groove 201. A first motor 4 is fixedly connected to the front end of the first connecting frame 2, and the output shaft of the first motor 4 is fixedly connected to the first screw 3. The upper left and right side walls of the first connecting seat 5 are in contact with the inner wall of the first through groove 201 and are screwed together with the first screw 3. When the first motor 4 drives the first screw 3 to rotate, the first connecting seat 5 moves along the first screw 3 under the limiting and guiding action of the first through groove 201. In this embodiment, the rear end of the first connecting frame 2 is welded and fixed to the outer side of one of the first clamping plates.
[0026] The bottom of the first connecting seat 5 has a connecting plate 501 extending beyond the left side of the first connecting frame 2, and the connecting plate 501 is inclined downwards from front to back. The second connecting frame 6 is fixed to the front side of the front wall of the connecting plate 501.

In this embodiment, the connecting plate 501 and the first connecting seat 5 are integrally formed structures.
[0027] A fixed shaft 12 is fixedly connected to the right side of the first connecting frame 2 near the mounting base 1. A pull rope (not shown in the figure) is wound around the fixed shaft 12, and the other end of the pull rope is connected to the second mounting component 11.

Before lowering the shallow seismic profiler 13, the pull rope is first loosened from the fixed shaft 12 and the end of the pull rope is held to prevent the pull rope from falling into the water. Then, the shallow seismic profiler 13 is lowered. After it is placed in place, the operator wound the excess pull rope back around the fixed shaft 12. After the winding is completed, the end of the pull rope is fixed on the auxiliary ring 1202 to prevent the pull rope from being placed randomly, causing it to detach from the fixed shaft 12 or even fall apart and become entangled with other equipment. The pull rope and the second connecting seat 8 are used together to fix the shallow seismic profiler 13, effectively improving the installation stability of the shallow seismic profiler 13 in the water.
[0030] The working process of this embodiment is as follows:
[0031] The shallow seismic profiler 13 is fixed in the first mounting component 10 and the second mounting component 11. The mounting base 1 is fixed to the railing on the ship's side by U-bolts and nuts, so that the first connecting frame 2 extends out of the hull. In the initial state, the first connecting seat 5 is located on the side close to the mounting base 1, and the second connecting seat 8 is located on the side close to the second motor 9. The operator releases the pull rope from the fixed shaft 12, starts the first motor 4 to move the first connecting seat 5 forward, which drives the second connecting frame 6 to move forward. The second motor 9 is started to move the second connecting seat 8 forward and downward along the second screw 7, and finally the shallow seismic profiler 13 is put into the water. Finally, the excess pull rope is wound around the fixed shaft 12 and the end of the pull rope is tied to the auxiliary ring 1202.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
