[0019] In order to make the purpose, technical solutions and advantages of the utility model clearer and more understandable, the technical solutions of the utility model will be further described in detail below in conjunction with the drawings in the embodiments of the utility model.

[0020] Refer to Figures 1 to 5, a foldable and convenient disassembly and assembly multi-beam fixed bracket of the present utility model includes a connecting rod 2, a fixed bracket, a bracket back plate 4, a rotation adjustment connection assembly, a connecting rod positioning device, and two outer chucks 29. The bracket back plate 4 is fixedly installed on the hull. The two outer chucks 29 are symmetrically fixedly installed on the hull and are located above the bracket back plate 4. The connecting rod 2 is rotatably connected to the outer chuck 29 through the rotation adjustment connection assembly. A multi-beam device 16 is installed at the bottom end of the connecting rod 2. The fixed bracket is detachably installed at the top end of the connecting rod 2 and is used to connect a GNSS receiver. The connecting rod positioning device is installed on the bracket back plate 4 to fix the connecting rod 2 when it is in a vertical state.

[0021] The rotation adjustment connection assembly includes an adjustment plate 30, a buckle 5, and a sector connecting plate 31. The buckle 5 is arranged at the top end of the adjustment plate 30. A rolling shaft 33 is embedded at the bottom of the adjustment plate 30. One end of the buckle 5 is rotatably connected to the adjustment plate 30 and the other end can be fixed on the adjustment plate 30 through a tightening screw 14. There are two sector connecting plates 31 which are respectively fixedly installed on both sides of the bottom end of the adjustment plate 30. The two sector connecting plates 31 are respectively rotatably connected to the two outer chucks 29 through a rotation shaft 11. Through holes 24 for inserting a clamping post 18 are correspondingly formed on the sector connecting plate 31 and the outer chuck 29.

[0022] During installation, pass the connecting rod 2 through the buckle 5 and fix the connecting rod 2 by tightening the tightening screw 14. Then, the adjustment plate 30 can be rotated through the rotation shaft 11. The rotation of the adjustment plate 30 can drive the connecting rod 2 to rotate, thereby changing the angle of the connecting rod 2. When transporting the entire device, since the measurement position has not been reached, the connecting rod 2 can be lifted to a horizontal state. At this time, the clamping post 18 can be inserted into the through hole 24, so that the connecting rod 2 always remains in a horizontal state until the measurement position is reached. After that, take out the clamping post 18, rotate the connecting rod 2 to a vertical state for measurement. After the measurement is completed, place the adjustment plate 30 horizontally and loosen the buckle 5 to take out the connecting rod 2.

[0023] Since the rolling shaft 33 is arranged at the bottom of the adjustment plate 30, when inserting or taking out the connecting rod 2, the rolling shaft 33 can reduce the friction with the connecting rod 2 and is more labor-saving.

[0024] The fixed bracket includes an adjustable support rod 6, a fixed support rod 1 and a positioning disk 19. The adjustable support rod 6 and the fixed support rod 1 are symmetrically arranged on both sides of the positioning disk 19. The fixed support rod 1 is fixedly connected to the positioning disk 19, while the adjustable support rod 6 is rotatably installed on the positioning disk 19. The adjustable support rod 6 and the fixed support rod 1 can be connected to the GNSS receiver through a connecting screw 17. An insertion pin 8 that can pass through the adjustable support rod 6 is inserted into the positioning disk 19. At the top end of the connecting rod 2, two self-return spring pins are symmetrically arranged. The self-return spring pin includes a top plate 7, a movable plate 10, a column 21 and a telescopic spring 9. The bottom end of the column 21 is rotatably connected to the connecting rod 2. The top plate 7 is fixedly installed at the top end of the column 21. The movable plate 10 is slidably sleeved on the column 21. One end of the telescopic spring 9 is fixedly connected to the top plate 7 and the other end is fixedly connected to the movable plate 10. An embedding groove 32 adapted to the column 21 is formed on the positioning disk 19. Positioning holes 22 are arranged on both sides of the embedding groove 32 on the positioning disk 19. A tapered pin 20 adapted to the positioning holes 22 is arranged on the bottom surface of the movable plate 10.

[0025] When connecting the fixed bracket to the connecting rod 2, first pull the top plate 7 to make the column 21 open outward. Then place the positioning disk 19 at the top end of the connecting rod 2. Subsequently, hold the top plate 7 and hook the finger on the movable plate 10 to move the movable plate 10 upward. The telescopic spring 9 is compressed. At the same time, push the top plate 7 to make the column 21 gradually move to the vertical state and embed into the embedding groove 32 on the positioning disk 19. Then release the movable plate 10. Under the action of the telescopic spring 9, the movable plate 10 moves downward and abuts against the positioning disk 19. At the same time, the tapered pin 20 on the movable plate 10 embeds into the positioning holes 22. In this way, the positioning disk 19 can be fixed at the top end of the connecting rod 2.

[0026] The adjustable support rod 6 can rotate relative to the positioning disk 19. When transporting the equipment, the adjustable support rod 6 can be rotated so that it is on the same side as the fixed support rod 1, which can save space and facilitate transportation. During use, just unfold the adjustable support rod 6, then pass the insertion pin 8 through the adjustable support rod 6 to fix it, and then the GNSS receiver can be installed through the connecting screw 17.

[0027] The connecting rod positioning device includes a rope 23 and two groups of positioning components. The two groups of positioning components are symmetrically installed on the support back plate 4. The positioning component includes a conduit 15, a protective shell 3, a pulley 25, a torsion spring 12, a linkage shaft 26, a limit block 27, a limit plate 13 and a support column 28. The protective shell 3 is fixedly installed on the support back plate 4. The pulley 25 is rotatably installed in the protective shell 3. One end of the linkage shaft 26 is fixedly connected to the axle of the pulley 25 and the other end is rotatably inserted into the limit block 27. One end of the support column 28 is fixedly connected to the limit block 27 and the other end is fixedly connected to the protective shell 3. The torsion spring 12 is installed between the linkage shaft 26 and the protective shell 3. The tail end of the limit plate 27 is slidably inserted into the limit block 27 and is located between the support column 28 and the linkage shaft 26. The linkage shaft 26 and the limit plate 3 are connected by tooth engagement. The conduit 15 is fixed on the support back plate 4. Both ends of the rope 23 pass through two conduits 15 respectively and then extend into the corresponding protective shells 3 and are wound around the pulleys 25.

[0028] During measurement, the connecting rod 2 needs to be rotated to the vertical state. During this process, the user needs to first pull the rope body of the rope 23 between the two conduits 15, thereby synchronously driving the rotation of the two pulleys 25. Since the linkage shaft 26 is fixed to the axle of the pulley 25, when the pulley 25 rotates, the linkage shaft 26 will also rotate. Also, because the linkage shaft 26 and the limit plate 13 are connected by tooth engagement, the rotation of the linkage shaft 26 can drive the limit plate 13 to move outward, that is, the two limit plates 13 gradually open. Until the connecting rod 2 rotates to the vertical state, the connecting rod 2 is exactly between the two limit plates 13. At this time, only need to release the rope 23. Under the action of the torsion spring 12, the pulley 25 rotates in reverse, thereby driving the limit plate 13 to move inward, that is, the two limit plates 13 gradually close and clamp the connecting plate 2, and the fixing of the connecting rod 2 can be completed.
