Detailed Description

The invention is further described below with reference to the accompanying drawings:

the embodiment provides a hydraulic engineering detects sampling device, as shown in fig. 1, including mounting bracket 1, base 2, spacing seat 3, depression bar 4 and sampling tube 5, the one end of depression bar 4 is articulated (as shown in fig. 4) with the articulated thick stick 11 on the upper portion of mounting bracket 1, and the other end of depression bar 4 is equipped with handle 41, and the middle part of depression bar 4 is equipped with spacing groove 42 and lets a through-hole 43, and spacing groove 42 all sets up along the length direction of depression bar 4 with letting a through-hole 43. In this embodiment, the middle of the pressing rod 4 is provided with four rod bodies parallel to each other, two first rod bodies 44 parallel to each other are located on the upper portion of the pressing rod 4, two second rod bodies 45 parallel to each other are located on the lower portion of the pressing rod 4, a cavity between the first rod bodies 44 and the second rod bodies 45 is the limiting groove 42, and a cavity between the four rod bodies except the limiting groove 42 is the abdicating through hole 43.

The limiting seat 3 is fixedly connected with the middle part of the mounting frame 1, the limiting seat 3 is provided with a first limiting through hole 31, the base 2 is fixedly connected with the lower part of the mounting frame 1, the base 2 is provided with a second limiting through hole 21, and the limiting seat 3 is arranged between the pressing rod 4 and the base 2; as shown in fig. 5, the high-position end of the sampling tube 5 is provided with a limiting block 51, the high-position end of the sampling tube 5 extends into the abdicating through hole 43, the limiting block 51 is clamped in the limiting groove 42, and the low-position end of the sampling tube 5 passes through the first limiting through hole 31 and extends into the second limiting through hole 21.

When a user holds the handle 41 and presses down, the distance between the handle 41 and the hinge point is greater than the distance between the limiting block 51 and the hinge point, so that the pressure rod 4 can generate a large downward pressure on the sampling tube 5, and the sampling tube 5 can be conveniently inserted into hard soil for sampling. Although the pressure lever 4 applies two component forces in the vertical and horizontal directions to the sampling tube 5 at the same time when the sampling tube 5 is just pressed down, the sampling tube 5 is subjected to small resistance by soil, and the applied downward pressure is small, so that the pressure lever 4 and the limiting block 51 cannot be locked. Along with the further downward rotation of depression bar 4, the depression bar 4 reduces to sampling tube 5 pressure direction and the contained angle of sampling tube 5 length direction gradually, and when depression bar 4 was horizontal, depression bar 4 only applyed vertical decurrent effort to sampling rod 5. The friction force between the limiting block 51 and the pressing rod 4 can be reduced by smearing lubricating oil on the middle part of the pressing rod 4. In-process is mentioned to depression bar 4, and depression bar 4 can exert great pull up to sampling tube 5 equally, is convenient for overcome the frictional force between 5 periphery walls of sampling tube and the soil, easily pulls out sampling tube 5 from soil. After sampling, a discharging rod is inserted into the sampling pipe 5 from the top or the bottom of the sampling pipe, and soil samples in the sampling pipe are pushed to be discharged from the bottom or the top.
