[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Underwater surveying unmanned surface vessel placement rack, such as Figure 1 As shown, it includes two parallel and symmetrically arranged square frames, which are connected by two crossbars 22. Each crossbar 22 is fixedly connected to the corresponding square frame at both ends by splicing components. Each of the two square frames has an arc plate 25 on the same side. Each arc plate 25 is connected to a support rod 43 by two buffer components. The two support rods 43 are connected by two U-shaped rods 44. The U-shaped rods 44 are used to connect the support rods 43 on the left and right sides, which can prevent the unmanned boat from tilting to one side when it is placed.

[0026] The square frame includes two uprights 1 and two connecting rods 24. The two uprights 1 are symmetrically arranged, and the two connecting rods 24 are symmetrically arranged. The two uprights 1 and the two connecting rods 24 are connected end to end to form a closed square frame. Adjacent uprights 1 and connecting rods 24 are connected by connecting components.

[0027] like Figure 2 As shown, the connecting component includes a connecting block 23, which is bent. Both ends of the connecting block 23 pass through the ends of the connecting rod 24 and the upright 1, respectively. The connecting block 23 is fixedly connected to the connecting rod 24 and the upright 1 by a number of second fixing bolts 33. During operation, the connecting block 23 can be connected to the upright 1 and the connecting rod 24 by the second fixing bolts 33. After use, the upright 1 and the connecting rod 24 can be disassembled for easy storage and movement.

[0028] like Figure 3As shown, the splicing assembly includes a three-way sleeve 21, which is fixedly sleeved onto the middle part of the corresponding upright 1 by a first fixing bolt 31. During installation, the upright 1 can be inserted into the three-way sleeve 21. One side of the three-way sleeve 21 has an opening to facilitate the insertion of the crossbar 22. The two ends of the crossbar 22 are respectively sleeved into the two corresponding three-way sleeves 21. The two ends of the crossbar 22 are respectively fixedly connected to the two three-way sleeves 21 by quick-release bolts 32. The upright 1 and the crossbar 22 are set perpendicularly, and the crossbar 22 can be quickly disassembled by the first fixing bolt 31 and the quick-release bolt 32. The quick-release bolt 32 is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case.

[0029] The arc-shaped plate 25 is fixedly mounted on the connecting rod 24 by the third fixing bolt 34, which facilitates disassembly and installation.

[0030] like Figure 4 , 5 As shown, the buffer assembly includes two sealing tubes 41, which are vertically mounted on the arc-shaped plate 25. Each sealing tube 41 is hollow. A sliding rod 42 is slidably fitted inside the end of the sealing tube 41 away from the arc-shaped plate 25. The end of the sliding rod 42 away from the sealing tube 41 is connected to a support rod 43. A sealing gasket 46 is connected to the end of the sliding rod 42 inside the cavity of the sealing tube 41. The outer diameter of the sealing gasket 46 is equal to the inner diameter of the sealing tube 41. Several circular holes 401 are formed on the sealing gasket 46. The diameter of the circular holes 401 is small, which restricts the flow rate of the fluid. A compression spring 45 is fitted over the sliding rod 42. One end of the compression spring 45 is connected to the sealing tube 41, and the other end is connected to the support rod 43. A limiting ring is provided at the upper end of the cavity of the sealing tube 41. The inner diameter of the limiting ring is smaller than the outer diameter of the sealing gasket 46. This design prevents the sliding rod 42 from detaching from the sealing tube 41.

[0031] Working principle: Before use, it needs to be assembled. First, insert the upright 1 into the tee sleeve 21. When the tee sleeve 21 moves to the middle position of the upright 1, use the first fixing bolt 31 to fix the tee sleeve 21 to the upright 1. Then, use the second fixing bolt 33 to fix the connecting block 23 to the upper and lower ends of the upright 1, and use the second fixing bolt 33 to fix the connecting rod 24 to the connecting block 23. In the same way, multiple uprights 1, tee sleeves 21, connecting blocks 23 and connecting rods 24 can be assembled into two rings.

[0032] Then, insert both ends of the crossbar 22 into the tee sleeve 21 and fix them with quick-release bolts 32 to complete the frame assembly. Finally, use the third fixing bolt 34 to fix the arc plate 25 to the connecting rod 24 to complete the assembly of the device.

[0033] When the device is in use, the unmanned ship is directly placed on the support rod 43, the gravity makes the support rod 43 move downward, the compression spring 45 is compressed, the compression spring 45 generates a reaction force, slows down the descending speed of the unmanned ship, and plays a preliminary buffering role. At the same time, the sealing pad 46 in the sealing tube 41 moves downward with the sliding rod 42, the circular hole 401 on the sealing pad 46 limits the flow rate of the fluid, generates a damping effect, further buffers the impact force of the unmanned ship, avoids damage to the device and the unmanned ship, and the U-shaped rod 44 connects the left and right two support rods 43 to prevent the unmanned ship from tilting when placed, and ensures stable placement.
