According to the design of the retaining wall for blocking loose soil, as shown in fig. 1 and 2, after detection, the device can take out internal components through the outer wall body, and blocks the pressing plate sliding groove 11, the pressure detection port 12 and the cleaning rod sliding port 13 through the blocking blocks, so that the phenomenon that the appearance is lowered due to the exposure of the rocking handle 2 is avoided.
First, a first advantageous point of the present invention is explained by the following:
when the operation starts, as shown in fig. 3, the soil pressure wall surface to be measured is selected for detection, at this time, the rocking handle 2 starts to rotate, as shown in fig. 5, the rocking handle 2 drives the pressure detection rod 21 to rotate simultaneously in the rotating process, at this time, due to the rotation of the pressure detection rod 21 and the threaded connection between the pressure detection rod 21 and the pressure detection port 12, the pressure detection rod 21 starts to extend and extrude towards the soil inside the retaining wall, at this time, the soil pressure can arch towards the upper end due to the loosened soil, and the numerical value displayed on the pressure numerical value display instrument 5 is not a real numerical value;
at this time, the swing handle 2 is rotated continuously, as shown in fig. 6, due to the rotation of the swing handle 2 and the engagement between the first bevel gear 32 and the pressure detection rod 21, the first bevel gear 32 starts to rotate, thereby driving the second bevel gear 33 to rotate, during the rotation of the connection rod 3, due to the engagement between the second bevel gear 33 and the sliding rod 41, the sliding rod 41 moves downwards, thereby driving the pressing plate 44 to slide downwards, when the pressing plate 44 moves to be parallel to the soil surface, at this time, the swing handle 2 is rotated continuously, due to the effect that the soil at the end where the swing handle 2 is extended out of the rotation is pressed downwards, the soil can only spread towards both ends, at this time, due to the wide plate length of the pressing plate 44, the soil spreads towards both ends very slowly, at this time, the rotation is continued, the value displayed at the end of the pressure value display 5 at each rotation tends to be the same, at the moment, the numerical value is recorded, so that the accuracy in detection is guaranteed.
From what is described herein, it can be seen that: according to the soil detection device, the handle 2, the pressure detection rod 21, the pressure numerical value display instrument 5 and the soil compacting precision measurement device are shaken, the manual force effect and the wall body arrangement are utilized, the soil is detected by enclosing the soil inside the retaining wall, meanwhile, the soil at the measuring end is stabilized by utilizing the driving effect, and the precision of the measured numerical value is guaranteed.
Secondly, a second advantageous point of the present invention is explained by the following:
after the detection is finished, as shown in fig. 3, because the elastic force of the abutting spring 24 is greater than the thread resistance between the pressure detection rod 21 and the pressure detection port 12, the rocking handle 2 is released, because the abutting spring 24 is always in a compressed state, the pushing plate 23 starts to be pushed to move towards the outer wall end, meanwhile, because the pushing plate 23 is in sliding connection with the pressure detection rod 21, the pushing block 22 is fixedly connected with the pressure detection rod 21, the pushing block 22 is kept in abutting but not fixedly connected with the pushing plate 23, when the pushing plate 23 moves outwards, the pushing block 22 is pushed to move, because the thread structure between the pressure detection rod 21 and the pressure detection port 12 is arranged, the pressure detection rod 21 starts to rotate outwards quickly, and thus the centrifugal cleaning function of the measurement end of the pressure detection rod 21 is realized under the centrifugal action;
meanwhile, as shown in fig. 4, the pushing plate 23 moves towards the soil blocking end in the manual pushing process of the rocking handle 2 before measurement, so as to drive the cleaning rod 25 to move towards the soil blocking end, at this time, as the cleaning rod 25 moves outwards, the air inlet valve 27 starts to perform an air suction process, when the pushing plate 23 performs a return motion, the cleaning rod 25 starts to extrude the air inside the cleaning air pipe 26, and as the plurality of air outlet valves 28 correspond to the pressure detection rod 21, the air extruded during the return motion is released through the air outlet valves 28 and acts on the threaded end of the pressure detection rod 21, so that the pneumatic cleaning function of the second layer is realized.
From what is described herein, it can be seen that: according to the invention, through the elastic force action of the abutting spring 24 and the structural arrangement of the self-resetting cleaning device, the automatic resetting function of the rod body of the pressure detection rod 21 is realized, and meanwhile, the primary centrifugal cleaning and the subsequent pneumatic cleaning functions of the measuring end of the pressure detection rod 21 are realized by utilizing the pneumatic pressure action and the centrifugal action.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
