Description

Technical Field

[0001] This utility model relates to the field of geotechnical testing technology and belongs to a geotechnical permeability coefficient tester for geotechnical engineering. Background Technology

[0002] The soil permeability tester is mainly used to determine the permeability of soil and rock under different hydraulic gradients. By applying a head difference, it simulates the hydraulic gradient of soil and rock under actual engineering conditions, and calculates the permeability coefficient of soil and rock by measuring the flow rate and head loss.

[0003] Before the experiment, soil and rock samples need to be placed in a permeability container, and after the test, they need to be removed. However, the permeability container is generally of a certain depth, making placement and retrieval inconvenient and time-consuming. Furthermore, after completing a soil and rock permeability test, a large amount of mud remains inside the soil and rock sample analyzer, especially in the sample placement area. This mud adheres to the sample placement tank, the inner walls of the pipes, and other parts, requiring timely cleaning to ensure the smooth progress of subsequent experiments. Conventional cleaning methods not only consume a lot of manpower and time but are also difficult to completely remove the mud, which seriously affects the efficiency of subsequent soil sample replacement and installation, thus slowing down the overall testing progress.

[0023] See Figure 2 Specifically, the permeation assembly 4 further includes a supporting base plate 42, and the permeation tank 41 has a plurality of travel grooves 411 inside. The supporting base plate 42 has a plurality of mating mounting blocks 412 corresponding to the travel grooves 411 on its periphery. The mating mounting blocks 412 and the travel grooves 411 are slidably connected.

[0024] See Figure 2Specifically, the linkage component 5 includes a connecting clamp 51, the permeation tank 41 is connected to the connecting clamp 51, a sliding block 52 is connected to the other side of the connecting clamp 51, a slide rail 53 is connected to the middle of the support frame 2, the sliding block 52 and the slide rail 53 are slidably connected, the sliding block 52 is provided with an internal threaded hole 54, a transmission screw 55 is connected to the internal threaded hole 54 by a threaded engagement, the transmission screw 55 is movably connected to the support frame 2, and one end of the transmission screw 55 is connected to a first motor 56 through a coupling.

[0025] See Figures 3-4 Specifically, the flipping assembly 6 further includes a second motor 61, which is connected to the top of the support frame 2 via a motor mount. The second motor 61 is connected to a first transmission shaft 62 via a coupling, and the first transmission shaft 62 is fixedly connected to the mounting plate 63.

[0026] See Figures 3-4 Specifically, the cleaning assembly 8 includes a third motor 81, which is connected to the output end of the bidirectional cylinder 64. The output end of the third motor 81 is connected to a second drive shaft 82 via a coupling, and a cleaning brush 83 is connected to the second drive shaft 82.

[0027] See Figure 3 Specifically, the lifting assembly 9 includes a lifting cylinder 91, which is connected to the base 1, and the output end of the lifting cylinder 91 is connected to a lifting plate 92.

[0028] The working principle of this utility model:

[0029] Before the initial test, the permeation tank 41 is first moved to the top of the lifting assembly 9 via the linkage component 5. The first motor 56 is started, driving the transmission screw 55 to rotate. Through the threaded transmission, the sliding block 52, which is threaded with the transmission screw 55, moves along the slide rail 53, thereby causing the permeation tank 41 to move synchronously until it is above the lifting assembly 9. Then, the lifting cylinder 91 is started, lifting the lifting plate 92 upward. During the upward movement of the lifting plate 92, it first contacts the bottom of the support base plate 42 and continues to push outward. The support base plate 42 is pushed upward along the stroke groove 411 until it moves to the top of the permeation tank 41. At this time, the sample is placed on the support base plate 42. Then, the lifting cylinder 91 retracts, and the lifting plate 92 moves downward until it returns to the initial position. Then, the permeation tank 41 is moved to the top of the water collection tank 3 and the bottom of the tank cover 7 through the linkage component 5. The bidirectional cylinder 64 is activated to drive the tank cover 7 to press down onto the permeation tank 41, and then the permeation test is carried out.

[0030] After an experiment is completed, the bidirectional cylinder 64 moves the barrel cover 7 upward, and through the linkage component 5, it drives the permeation barrel 41 above the lifting component 9. The lifting component 9 performs the same action, and the lifting cylinder 91 lifts up the lifting plate 92, which in turn lifts the support base plate 42, making it easier to remove the sample. Then, the linkage component 5 moves the permeation barrel 41 back to its original position. The flipping component 6 drives the cleaning component 8 and the barrel cover 7 to flip. The second motor 61 drives the first drive shaft 62 to rotate. The first drive shaft 62 drives the mounting plate 63 to flip, which in turn drives the bidirectional cylinder 64 to flip in the same direction. The cleaning component 8 moves above the permeation barrel 41. The bidirectional cylinder 64 is activated, driving the cleaning component 8 into the permeation barrel 41. The third motor 81 is activated, driving the second drive shaft 82 to rotate, which in turn drives the cleaning brush 83 to rotate, thus completing the cleaning treatment of the inner wall of the permeation barrel 41.

Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
