Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 As shown:

[0023] An underwater soil sampling device for water conservancy geological survey includes a sampling tube 101 and handles 102 symmetrically arranged on the top of the outer side of the sampling tube 101.

[0024] In this implementation plan: In order to solve the technical problems existing in the prior art, such as the above-disclosed background technology, "when the current underwater soil sampling is carried out, river water can easily enter the sampling tube 101. The presence of water will dilute the soil sample, causing the concentration of soil components to change, thereby affecting the accurate determination of the content of various substances in the soil. For example, the assessment of the content of minerals, organic matter, etc. may be biased, reducing the effectiveness of the equipment." In combination with the use, this problem is obviously a real and difficult problem to solve.

[0025] Furthermore:

[0026] like Figures 1-4 As shown:

[0027] Based on the above: a sealing disc 104 is slidably installed inside the sampling tube 101, which is used to seal the port of the sampling tube 101;

[0028] A pull rod 103 is fixed to the top of the sealing disc 104, and a strip plate 106 is welded to the surface of the pull rod 103;

[0029] The top end of the sampling tube 101 is equipped with a locking mechanism 2 for locking the position of the strip plate 106;

[0030] The locking mechanism 2 includes a mounting block 201 fixed to the top of the sampling tube 101, an L-shaped rod 204 sliding inside the mounting block 201, and a fixing plate 203 fixed to the surface of the L-shaped rod 204.

[0031] A spring 202 is wound around the surface of the L-shaped rod 204. The two ends of the spring 202 are fixedly connected to the mounting block 201 and the fixing plate 203, respectively. The surface of the strip plate 106 has multiple sets of equidistantly arranged locking holes 205 that are adapted to the L-shaped rod 204. The L-shaped rod 204 is inserted into one set of locking holes 205. The interior of the mounting block 201 has a moving hole adapted to the L-shaped rod 204. The L-shaped rod 204 and the mounting block 201 are slidably connected through this moving hole.

[0032] The top of the sampling tube 101 is provided with a sliding hole that is adapted to the pull rod 103 and the strip plate 106. The pull rod 103 and the strip plate 106 are slidably connected through the sliding hole provided in the sampling tube 101.

[0033] In this implementation plan: When using the underwater soil sampling equipment for water conservancy geological surveys, firstly, the L-shaped rod 204 is pulled, causing it to slide within the mounting block 201. The L-shaped rod 204 drives the fixed plate 203 to move, which in turn stretches the spring 202, causing the L-shaped rod 204 to disengage from the locking hole 205 and releasing the position lock on the strip plate 106. The design of the strip plate 106 limits the movement of the pull rod 103, preventing it from rotating on the sampling tube 101. Then, the pull rod 103 is pushed, which in turn moves the sealing plate 104 until it is moved to the desired position. At the bottom of the sampling tube 101, release the L-shaped rod 204, allowing the L-shaped rod 204 to be reinserted into the locking hole 205, thereby locking the strip plate 106 and locking the pull rod 103. This prevents the sealing disc 104 from moving inside the sampling tube 101. Then, hold the handle 102 and insert the sampling tube 101 into the water. During this process, river water will not enter the interior of the sampling tube 101. When the bottom of the sampling tube 101 is in the soil at the bottom of the river, pull the L-shaped rod 204 again to release the position lock of the strip plate 106. Then, pull the pull rod 103 upward and move the sealing disc 104 upward simultaneously.

[0034] After the pull rod 103 pulls the sealing plate 104 a certain distance, the L-shaped rod 204 is released to lock the strip plate 106 again. While pulling the pull rod 103, the sampling tube 101 is pressed down by the handle 102, so that the sampling tube 101 is inserted into the soil in the water, allowing the soil to enter the interior of the sampling tube 101. Then the sampling tube 101 is taken out, thus completing the soil sampling. Through this operation, when sampling the soil, the sampling tube 101 effectively reduces the amount of river water entering the interior of the sampling tube 101, thereby avoiding water dilution of the soil sample and changes in the concentration of soil components. This does not affect the accurate determination of the content of various substances in the soil, reduces the deviation of the substance content assessment, improves the use effect of the equipment, and meets the actual use needs.

[0035] Furthermore;

[0036] In an optional embodiment, the surface of the strip plate 106 is provided with a strip groove, and the surface of the strip plate 106 is provided with scale lines 107 located in the strip groove.

[0037] In this embodiment: then the L-shaped rod 204 is pulled again to release the position lock of the strip plate 106, and then the pull rod 103 is pulled up, which in turn drives the sealing plate 104 to move up synchronously;

[0038] By observing the scale line 107 on the bar plate 106, the height to which the pull rod 103 is pulled can be better seen, thus enabling the determination of a certain depth for subsequent soil sampling. Since the scale line 107 is within the groove of the bar plate 106, the scale line 107 will not be scratched due to friction when the bar plate 106 slides on the top of the sampling tube 101, further improving the effectiveness of this structure.

[0039] Furthermore;

[0040] In an optional embodiment, a sealing ring 105 is fixed to the outer surface of the sealing disc 104 to enhance the seal between the sampling tube 101 and the sealing disc 104.

[0041] In this embodiment, the sealing ring 105 can increase the sealing between the sampling tube 101 and the sealing plate 104, preventing water from entering the interior of the sampling tube 101 through the gap between the sampling tube 101 and the sealing plate 104.

[0042] Furthermore;

[0043] In an optional embodiment, a limiting and fixing mechanism 3 is installed on the locking mechanism 2. The limiting and fixing mechanism 3 includes a rotating ring 301 rotatably connected to the outer surface of the fixed disk 203 via a bearing, an abutting rod 302 fixed to the surface of the mounting block 201, and a sliding groove 304 formed on the surface of the rotating ring 301. The rotating ring 301 slides on the abutting rod 302 through the sliding groove 304. An abutting groove 303 is formed on the side of the rotating ring 301 near the sliding groove 304. One end of the abutting rod 302 is inserted into the interior of the abutting groove 303 to limit and fix the position of the rotating ring 301.

[0044] In this embodiment: while the L-shaped rod 204 is pulled, the fixed plate 203 and the rotating ring 301 move synchronously, so that the groove 304 of the rotating ring 301 slides on the abutting rod 302. When the rotating ring 301 disengages from the abutting rod 302, the rotating ring 301 is then rotated, so that the abutting groove 303 of the rotating ring 301 is locked at one end of the abutting rod 302. This allows the positions of the rotating ring 301 and the fixed plate 203 to be temporarily locked, eliminating the need to continuously pull the L-shaped rod 204 by hand, and further improving the practicality and flexibility of the equipment.

[0045] The working principle and usage process of this utility model: When using this underwater soil sampling device for water conservancy and geological surveys, firstly, pull the L-shaped rod 204, causing it to slide within the mounting block 201. The L-shaped rod 204 drives the fixed plate 203 to move, which in turn stretches the spring 202, causing the L-shaped rod 204 to disengage from the locking hole 205 and releasing the position lock on the strip plate 106. The design of the strip plate 106 limits the position of the pull rod 103, preventing it from rotating on the sampling tube 101. Then, push the pull rod 103, which in turn pushes the sealing plate 101. 04. Move the sealing disc 104 until it reaches the bottom of the sampling tube 101. Then, release the L-shaped rod 204, allowing it to re-insert into the locking hole 205, thereby locking the strip plate 106 and the pull rod 103. This prevents the sealing disc 104 from moving within the sampling tube 101. Then, holding the handle 102, insert the sampling tube 101 into the water. During this process, river water will not enter the sampling tube 101. When the bottom of the sampling tube 101 is in the soil at the bottom of the river, pull the L-shaped rod 204 again to release the strip plate 106. Lock the lever 103, then pull it upwards, causing the sealing plate 104 to move upwards simultaneously. By observing the scale line 107 on the strip plate 106, the height to which the lever 103 is pulled can be better determined, thus allowing for the assessment of the appropriate soil sampling depth. Since the scale line 107 is within the groove of the strip plate 106, friction will not scratch the scale line 107 when the strip plate 106 slides on top of the sampling tube 101, further improving the effectiveness of this structure. After pulling the lever 103 and extending the sealing plate 104 a certain distance, release the L-shaped rod 204 and reposition the strip plate 106. Locking is achieved by simultaneously pulling the lever 103 and pressing down the sampling tube 101 with the handle 102, causing the sampling tube 101 to be inserted into the soil in the water, allowing soil to enter the interior of the sampling tube 101. The sampling tube 101 is then removed, thus completing the soil sampling. Through this operation, the sampling tube 101 effectively reduces the amount of river water entering the interior of the sampling tube 101 during soil sampling, thereby avoiding water dilution of the soil sample and changes in the concentration of soil components. This does not affect the accurate determination of the content of various substances in the soil, reduces the deviation in the evaluation of substance content, improves the effectiveness of the equipment, and meets the actual use requirements.While the L-shaped rod 204 is pulled, the fixed plate 203 and the rotating ring 301 move synchronously, causing the groove 304 of the rotating ring 301 to slide on the abutment rod 302. When the rotating ring 301 disengages from the abutment rod 302, the rotating ring 301 is then rotated, causing the groove 303 of the rotating ring 301 to engage with one end of the abutment rod 302. This temporarily locks the positions of the rotating ring 301 and the fixed plate 203, eliminating the need to continuously pull the L-shaped rod 204, further improving the practicality and flexibility of the equipment.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
