[0036] This utility model provides a device for measuring the moisture content of cohesive soil used in dike filling.

[0037] Please see Figures 1-4 The device includes a main control component 1, with a handle 6 fixedly connected to the bottom of the main control component 1. The surface of the handle 6 is treated with friction. A switch for controlling the rotation of the servo motor 5 is installed on the handle 6, making it convenient for testing personnel to use the device.

[0038] A servo motor 5 is externally fixedly installed on the main control component 1. The measuring positioning cylinder 2 is fixedly connected to the output shaft of the servo motor 5. When the user controls the servo motor 5 to start through the switch on the handle 6, the output shaft of the servo motor 5 can drive the measuring positioning cylinder 2 to rotate, thereby providing drilling power for the measuring positioning cylinder 2.

[0039] Please see Figure 1 and Figure 2 The measurement main control component 1 has a display screen 7 fixedly installed inside. The measurement main control component 1, servo motor 5 and display screen 7 are all existing technologies. In this application, their installation method and working principle will not be described in detail. The measurement main control component 1 can connect the various components of the device and provide support for the operation of other components. The display screen 7 can display the soil moisture content detected by the soil moisture content probe 404, which is convenient for the testing personnel to observe.

[0040] Please see Figure 1 , Figure 2 and Figure 3 The outer surface of the main control component 1 is rotatably connected to the measuring positioning cylinder 2. The surface of the measuring positioning cylinder 2 is engraved with scale lines, which makes it convenient for users to drill holes at the corresponding depths of soil according to the requirements of the soil to be tested. A conical drill bit is installed at the end of the measuring positioning cylinder 2. When the measuring positioning cylinder 2 rotates, the resistance of the measuring positioning cylinder 2 can be reduced by the drill bit, thereby reducing the workload of using this device.

[0041] Please see Figure 3 The measuring positioning cylinder 2 is equipped with a measuring mechanism 4. The measuring mechanism 4 includes a transmission rod 401 that slides inside the measuring positioning cylinder 2. The end of the transmission rod 401 is rotatably connected to a rotating disk 408. A lever 409 is fixedly connected to the outer surface of the rotating disk 408. A groove is opened on the outer surface of the measuring positioning cylinder 2. The lever 409 slides inside the groove. The user can move the lever 409 to control the sliding of the transmission rod 401. When the lever 409 slides inside the groove, it can drive the transmission rod 401 to slide through the rotating disk 408. The two ends of the groove have slots. The testing personnel can rotate the lever 409 and lock the lever 409 into the slots to keep the lever 409 stable, thereby preventing the transmission rod 401 from sliding on its own.

[0042] A spring 410 is provided on the outside of the rotating disk 408. The two ends of the spring 410 are fixedly connected to the rotating disk 408 and the measuring positioning cylinder 2, respectively. The elastic potential energy of the spring 410 is sufficient to pull the transmission rod 401 to reset, thereby giving the lever 409 a pulling force, so that the lever 409 can be stably locked in the slot, preventing the lever 409 from falling out of the slot on its own. The small amplitude of shaking caused by the characteristics of the spring 410 itself is within the acceptable range of this application and will not affect the stability of the lever 409.

[0043] Please see Figure 3 and Figure 4 A connecting rod 405 is fixedly connected to the end of the transmission rod 401, and a fixing rod 406 is fixedly connected to the end of the connecting rod 405. A protective collar 3 is slidably connected to the outer surface of the measuring positioning cylinder 2. Both ends of the fixing rod 406 are fixedly connected to the protective collar 3. The protective collar 3 serves to protect the soil moisture content probe 404 and prevent soil from entering the sliding groove 407 during drilling, which would affect the accuracy of the soil moisture content probe 404. The diameter of the protective collar 3 is smaller than the diameter of the drill bit so that the protective collar 3 will not experience greater resistance when the measuring positioning cylinder 2 is drilling.

[0044] The end of the transmission rod 401 is hinged to a hinge rod 402 via a pin, and the end of the hinge rod 402 is hinged to a sliding column 403 via a pin. A sliding groove 407 is provided on the outer surface of the measuring positioning cylinder 2, and the sliding column 403 slides inside the sliding groove 407. The sliding groove 407 can provide a limiting and supporting effect for the sliding of the sliding column 403 to ensure the sliding stability of the sliding column 403. The hinge rod 402, the sliding column 403, the soil moisture probe 404, and the sliding groove 407 are symmetrically distributed inside the measuring positioning cylinder 2 to facilitate the simultaneous detection of different positions of the soil at a specified depth by the two sliding columns 403, thereby improving the measurement accuracy of the device.

[0045] A soil moisture content probe 404 is fixedly installed at the end of the sliding column 403. The soil moisture content probe 404 is a sensor used to measure the moisture content in the soil. When the soil moisture content probe 404 extends out of the measuring positioning cylinder 2, its end will contact the soil at that location to detect the moisture content of the soil and display the detection result on the display screen 7. The soil moisture content probe 404 is prior art and will not be described in detail in this application.

[0046] When the transmission rod 401 moves, it can drive the sliding column 403 to slide inside the sliding groove 407 through the hinge rod 402, thereby changing the position of the soil moisture content probe 404. This allows the soil moisture content probe 404 to extend out of the measuring positioning cylinder 2 to detect the moisture content of the soil, and to retract back into the measuring positioning cylinder 2 after the detection is completed, thus avoiding damage to the soil moisture content probe 404 caused by external factors.

[0047] When the transmission rod 401 slides inside the measuring positioning cylinder 2, it can drive the protective collar 3 to slide on the surface of the measuring positioning cylinder 2 through the connecting rod 405 and the fixing rod 406, thereby removing the protective collar 3 from obstructing the sliding groove 407; there is a certain distance between the soil moisture probe 404 and the top of the sliding groove 407, so that the protective collar 3 has been removed from the sliding groove 407 before the soil moisture probe 404 protrudes out of the sliding groove 407, avoiding the protective collar 3 from hindering the extension and retraction of the soil moisture probe 404.

[0048] By setting up the measuring mechanism 4, it is convenient to extend the soil moisture content probe 404 out of the measuring positioning cylinder 2 after it has penetrated to a certain depth in the soil, so as to detect the moisture content of the cohesive soil material used for filling the dike at that location. This reduces the steps of changing the drill bit and enables rapid detection of soil at different depths, greatly improving the ease of use of the device.

[0049] Working principle: When the testing personnel use this device to measure the moisture content of the cohesive soil used for dike filling, they first move the device to a suitable measurement position, then press the control switch on handle 6 to start the servo motor 5 and drive the measuring positioning cylinder 2 to rotate. As the measuring positioning cylinder 2 rotates, it drills holes in the dike filling soil. The user precisely controls the drilling depth of the measuring positioning cylinder 2 by referring to the scale lines on the surface of the measuring positioning cylinder 2 according to the actual depth of the soil being tested. After drilling to the desired position, the switch is released, and then the lever 409 is moved to the other end of the slide. The movement of the lever 409 is controlled by the spring 41. The transmission rod 401 slides inside the measuring positioning cylinder 2. The sliding of the transmission rod 401 can move the protective collar 3 away from the sliding groove 407 through the connecting rod 405 and the fixing rod 406. At this time, the soil moisture content probe 404 will extend out of the sliding groove 407 under the push of the hinge rod 402 and the sliding column 403, thereby detecting the soil moisture content at this position and displaying the detection result on the display screen 7. After the detection is completed, the soil moisture content probe 404 can be retracted into the measuring positioning cylinder 2 simply by resetting the lever 409, which improves the convenience of detecting the moisture content of deep soil.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
