The setting of the water baffle 7 can block the flow of water when the water sampling bottle body 51 absorbs water samples to the inside, so as to prevent the water flow from driving underwater debris into the water sampling bottle body 51 when the water sampling bottle body 51 absorbs water samples.

[0044] like Figure 6 , Figure 7 and Figure 8 As shown, the retaining assembly 8 includes a retaining plate 81 and a sliding support plate 84, both ends of the retaining plate 81 are fixedly connected with a gear shaft 82 and a locking rod 83, one end of the sliding support plate 84 located inside the support frame 3 is fixedly connected with a pair of tooth plates 85, and a spring plate 86 is fixedly connected inside the sliding support plate 84. The retaining plate 81 is hinged to the support frame 3, and the retaining plate 81 matches the hole specifications at the bottom of the first bracket 41. The gear shaft 82 is meshed with the tooth plate 85, and the sliding support plate 84 is slidably connected to the inside of the support frame 3, and the end of the sliding support plate 84 away from the tooth plate 85 extends to the outside of the support frame 3, and one end of the spring plate 86 is fixedly connected to the support frame 3.

[0045] The above scheme is adopted: by setting up a soil retaining assembly 8, the soil retaining plate 81 blocks the bottom of the soil sampling tube 44 after the soil sampling tube 44 completes soil sampling to prevent the soil sample from falling, the gear shaft 82 and the tooth plate 85 are set to drive the soil retaining plate 81 to flip, and the elastic piece 86 pulls the sliding support plate 84 to move, so that the sliding support plate 84 drives the gear shaft 82 to rotate through the tooth plate 85, so that the soil retaining plate 81 is flipped to the bottom of the soil sampling tube 44, and the locking rod 83 set at one end of the gear shaft 82 can lock the locking rod 83 to fix the soil retaining plate 81 and prevent it from flipping, so that the soil retaining plate 81 is fixed to the bottom of the soil sampling tube 44 to block the bottom of the soil sampling tube 44.

[0046] like Figure 6 , Figure 7 and Figure 8 As shown, the locking assembly 9 includes a first sliding plate 91 and a fixed base 96, the first sliding plate 91 is slidably connected with a second sliding groove 92, the second sliding groove 92 is slidably connected with a locking push plate 93, the first sliding plate 91 has a pair of elastic blocks 94 hinged at the bottom, the locking push plate 93 is fixedly connected with a pair of rotating blocking rods 95 at the lower end, and the fixed base 96 is slidably connected with an inclined blocking block 97. The first sliding plate 91 and the fixed base 96 are located at both ends of the support frame 3, the second sliding groove 92 penetrates the support frame 3 and extends to the upper end of the support frame 3, the top of the second sliding groove 92 is bent and abuts against the raised block outside the water collection bottle body 51, the second sliding groove 92 is located inside the blocking rod 83, the elastic block 94 abuts against the blocking rod 83, the rotating blocking rod 95 abuts against the support frame 3, the fixed base 96 is located inside the blocking rod 83, the inclined blocking block 97 abuts against the blocking rod 83 and limits the blocking rod 83.

[0047] The above scheme is adopted: by setting a locking assembly 9 to lock and unlock the retaining assembly 8, the second slide groove 92 locks the elastic block 94, and the elastic block 94 limits the positioning rod 83. When the water sampling bottle body 51 moves upward to collect water samples, the water sampling bottle body 51 pushes the second slide groove 92 to move upward synchronously through the raised block, so that the rotating block rod 95 is squeezed over the support frame 3 and moves to the upper side of the support frame 3. At the same time, the elastic block 94 contacts the positioning rod 83 and is squeezed and turned over. At this time, the rotating block rod 95 is squeezed by the support frame 3 to be retracted into the second slide groove 92, so that the locking push plate 93 is unlocked. The elastic card block 94 is synchronously unlocked and can be turned over, so that the locking rod 83 is unlocked, but at this time the bottom of the support frame 3 is in contact with the bottom of the water, and the retaining plate 81 cannot be turned over. After the soil sample is taken, the retaining plate 81 is released from the contact with the bottom of the water after the submersible body 1 rises, so that the retaining plate 81 is turned over. When the retaining plate 81 is turned over to the fixed base 96, the inclined locking block 97 will be squeezed inward to tighten, and then the locking rod 83 moves to the top of the inclined locking block 97, and the inclined locking block 97 limits the locking rod 83, so that the retaining plate 81 is turned over to the bottom of the first bracket 41 to block the soil sample and prevent it from falling.

[0048] The working principle and use process of the present invention are as follows: during operation, the submersible body 1 drives the support frame 3 to move to the bottom of the water, and then waits for a certain period of time to allow the floating mud to be taken away by the water flow, and then the reel-in machine arranged inside the submersible body 1 reels in the traction rope 64 to pull the sliding pressure rod 61 upward, and the sliding pressure rod 61 drives the water sampling bottle body 51 upward through the limit stop rod 62, so that the openings at the bottom and top of the water sampling bottle body 51 are opened, so that the air inside the water sampling bottle body 51 is discharged from the top of the water sampling bottle body 51, and at the same time, the water sampling bottle body 51 sucks the water sample into the water sampling bottle body 51 from the bottom, and then releases the traction rope 64, so that the spring 63 pulls the sliding pressure rod 61 downward, so that the sliding pressure rod 61 presses the water sampling bottle body 51 downward, so that the water sampling bottle body 51 contacts the rubber plug 53, and at the same time, the sealing ring 56 enters the sealing groove inside the water baffle 7, thereby completing the collection of water samples;

[0049] Then, soil samples are collected, and the hydraulic telescopic rod 43 pushes the soil sampling tube 44 downward to collect underwater soil samples. Then, the hydraulic telescopic rod 43 pulls the soil sampling tube 44 back into the first bracket 41, and then the submersible body 1 drives it to float up. At this time, the retaining plate 81 is freed from the conflict with the underwater soil, and the sliding support plate 84 is pulled by the spring piece 86 to drive the tooth plate 85 to move, so that the tooth plate 85 drives the gear shaft 82 to drive the retaining plate 81 to flip. When the retaining plate 81 flips to the fixed base 96, the inclined surface blocking block 97 is squeezed inward to tighten, and then the blocking rod 83 moves to the top of the inclined surface blocking block 97, and the inclined surface blocking block 97 limits the blocking rod 83, so that the retaining plate 81 is fixed to the bottom of the first bracket 41, and the bottom of the first bracket 41 is blocked to prevent the soil sample from falling.
