It investigates and studies the geological conditions such as rocks, strata, structures, minerals, hydrology, and landforms in a certain area. When sampling the soft soil of the river foundation, underwater soft soil sampling equipment will be used for sampling, but it still has the following disadvantages in actual use:

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figure 1-5 As shown, the utility model is a geological survey underwater soft soil sampling device, comprising a main rod body 1, a mounting opening 102 is provided at the circumferential position of the lower end of the main rod body 1, a sampling tube 4 is arranged inside the mounting opening 102, sampling openings 402 are provided on both sides of the sampling tube 4 extending out of the mounting opening 102, an inclined plate 404 is fixed to the inner side wall of the sampling tube 4 below the sampling opening 402, the interior of the sampling tube 4 is blocked by the inclined plate 404, so as to avoid the loss of soft soil, an assembly rod 2 is arranged just above the main rod body 1, a T-shaped round block 3 is fixed to the upper ends of the main rod body 1 and the assembly rod 2, two symmetrically arranged limit openings 302 are provided on the circumferential side of the T-shaped round block 3, and an assembly block 6 is provided inside the limit opening 302, and the lower end of the assembly rod 2 is sleeved in the inner position of the adjacent T-shaped round block 3 through the sleeve opening 201.

[0027] Among them Figure 1 , 2 As shown in , 4, a screw barrel 401 is fixed inside the sampling barrel 4 located above the sampling port 402, and a screw hole 103 connected to the inside of the screw barrel 401 is opened on the circumferential side of the main rod body 1, and a locking screw 5 is spirally connected to the inside of the screw barrel 401 and the screw hole 103. When the sampling barrel 4 is taken out from the inside of the installation port 102, the locking screw 5 is rotated and the locking screw 5 is screwed out from the internal position of the screw barrel 401 and the screw hole 103. At this time, the sampling barrel 4 can be taken out from the inside of the installation port 102. A plurality of water flow holes 403 distributed in an array are opened on the circumferential side of the sampling barrel 4 directly below the sampling port 402. When the main rod body 1 is drawn out under water, water in the sampling barrel 4 will flow out from the water flow holes 403. A conical head 101 is fixed on the lower end surface of the main rod body 1, and the conical head 101 can facilitate the movement of the main rod body 1 in soft soil.

[0028] Among them Figure 2 , 3 As shown in Figures 5 and 6, the circumferential side of the assembly rod 2 is provided with an insertion port 202 at the position corresponding to the assembly block 6, and the assembly block 6 is slidably inserted in the adjacent internal position of the insertion port 202, and the interior of the T-shaped round block 3 is provided with a movable opening 301 connected to the interior of the limiting opening 302, and the opposite sides of the two adjacent assembly blocks 6 are fixed with a movable plate 601 that slides in the internal position of the movable opening 301, and the width of the movable opening 301 is greater than the width of the limiting opening 302. Therefore, when the movable plate 601 is in the internal position of the movable opening 301, the limiting opening 302 limits the movable plate 601, so that the movable plate 601 cannot move from the limiting opening 302. The internal position of the positioning port 302 is disengaged to ensure that the assembly block 6 is stably assembled with the T-shaped round block 3, and an assembly spring 602 is fixed between the sides of the two movable plates 601 located in the internal position of the movable port 301. When the two assembly blocks 6 move toward the inside of the movable port 301, the assembly block 6 will drive the movable plate 601 to move inside the movable port 301, and the two movable plates 601 compress the assembly spring 602. Therefore, when the assembly block 6 is located in the internal position of the plug-in port 202, the assembly spring 602 will push the movable plate 601, so that the assembly block 6 can be stably located in the internal position of the plug-in port 202.

[0029] A specific application of this embodiment is: through the arrangement and use of the above structure, when it is necessary to sample the soft soil on the bottom of the water, the main rod body 1 is inserted into the bottom of the water, and the main rod body 1 is rotated, so that the main rod body 1 drives the cone head 101 to rotate, and the cone head 101 facilitates the main rod body 1 to be transferred into the soft soil, and the soft soil flows from the position of the sampling port 402 to the internal position of the sampling tube 4, so as to achieve the sampling effect in turn. At the same time, when the main rod body 1 is taken out, the main rod body 1 drives the sampling tube 4 to shake, and at this time, the inclined plate 404 below the sampling port 402 is used to shake the sampling tube 4. The soft soil inside the sample tube 4 is blocked to prevent the soft soil from being lost. At the same time, when the length of the main rod body 1 needs to be increased, the sleeve 201 at the lower end of the assembly rod 2 can be sleeved on the circumferential side of the T-shaped round block 3, so that the assembly block 6 is also located inside the sleeve 201. At this time, the assembly rod 2 is rotated to rotate the plug interface 202 to the position of the assembly block 6, and the assembly block 6 is pushed by the assembly spring 602 to be inserted into the inside of the plug interface 202, so that the assembly rod 2 can be assembled and connected with the main rod body 1 to increase the length of the main rod body 1.
