However, the existing base compaction material moisture content testing device still has shortcomings. Specifically, after the test, a large amount of soil will adhere to the outer wall of the probe, and the cleaning operation is time-consuming and laborious.

[0003] Therefore, a device for real-time detection of moisture content of compacted substrate based on dielectric constant is needed to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a device for real-time detection of the moisture content of a compacted substrate based on its dielectric constant, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A real-time detection device for the moisture content of a base compacted material based on dielectric constant includes a detection cylinder, a detection mechanism is provided inside the detection cylinder, a storage battery is installed inside the detection cylinder, and a controller is fixedly connected to the front of the detection cylinder.

[0007] The detection mechanism includes a soil moisture meter fixedly connected inside the detection cylinder. A cleaning plate is slidably connected inside the detection cylinder and to the outer wall of the probe of the soil moisture meter. A connecting block is fixedly connected to the outer wall of the cleaning plate. A piston rod is slidably connected to the outer wall of the connecting block inside the detection cylinder. Electromagnets are fixedly connected inside the piston rod, both above and below the connecting block. A fixing sleeve is fixedly connected to the outer wall of the piston rod inside the detection cylinder. A return spring is fixedly connected to the outer wall of the piston rod inside the fixing sleeve. A guide tube is fixedly connected to the top of the fixing sleeve. A miniature air pump is fixedly connected to the outer wall of the guide tube at the end away from the fixing sleeve. A data transmission antenna is installed inside the detection cylinder to the right of the miniature air pump.

[0008] As a preferred embodiment of this utility model, the detection cylinder is made of stainless steel, and the battery is connected to the controller by electrical connection.

[0009] As a preferred embodiment of this utility model, the cleaning plate and piston rod are both made of ABS plastic, the piston rod and the guide tube are both T-shaped structures, and the connection between the reset spring and the fixed sleeve, and the connection between the micro air pump and the detection cylinder are all fixed connections.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs a real-time detection device for the moisture content of a subgrade compacted material based on its dielectric constant. The device utilizes a detection mechanism to detect the moisture content of the subgrade compacted material. The detection cylinder is placed on the subgrade compacted material, and pressing the cylinder causes the probe of a soil moisture meter to insert into the soil. The controller activates the soil moisture meter, which measures the dielectric constant of the soil and calculates the moisture content based on this constant. The data transmission antenna transmits the data measured by the soil moisture meter to the monitoring center. After detection, pulling the detection cylinder causes the soil moisture meter to move upwards, pulling it out of the subgrade compacted material. The controller then activates a micro air pump, which sends air into a fixed sleeve through a guide tube. The air entering the fixed sleeve pushes a piston rod downwards. The downward-moving piston rod, through a connecting block, moves a cleaning plate downwards. The downward-moving cleaning plate scrapes off the soil adhering to the probe of the soil moisture meter, making the cleaning operation convenient. This solves the problem of existing subgrade compacted material moisture content detection devices having a large amount of soil adhering to the probe's outer wall after detection, making cleaning time-consuming and labor-intensive.

[0024] A real-time detection device for the moisture content of a base compacted material based on dielectric constant includes a detection cylinder 1, a detection mechanism 2 is installed inside the detection cylinder 1, a storage battery 3 is installed inside the detection cylinder 1, and a controller 4 is fixedly connected to the front of the detection cylinder 1.

[0025] The detection cylinder 1 is made of stainless steel, and the battery 3 is connected to the controller 4 by electrical connection.

[0026] In this embodiment, reference Figure 2 and Figure 3 The detection mechanism 2 includes a soil moisture meter 201 fixedly connected inside the detection cylinder 1. A cleaning plate 202 is slidably connected inside the detection cylinder 1 and to the outer wall of the probe of the soil moisture meter 201. A connecting block 203 is fixedly connected to the outer wall of the cleaning plate 202. A piston rod 204 is slidably connected to the outer wall of the connecting block 203 and inside the detection cylinder 1. An electromagnet 205 is fixedly connected to the inside of the piston rod 204 and above and below the connecting block 203. A fixing sleeve 206 is fixedly connected to the outer wall of the piston rod 204 and inside the detection cylinder 1. A return spring 207 is fixedly connected to the outer wall of the piston rod 204 and inside the fixing sleeve 206. A guide tube 208 is fixedly connected to the top of the fixing sleeve 206. A miniature air pump 209 is fixedly connected to the outer wall of the guide tube 208 and at the end away from the fixing sleeve 206. A data transmission antenna 210 is installed inside the detection cylinder 1 and to the right of the miniature air pump 209.

[0027] The cleaning plate 202 and piston rod 204 are both made of ABS plastic. The piston rod 204 and the guide tube 208 are both T-shaped structures. The reset spring 207 is fixedly connected to the fixed sleeve 206, and the micro air pump 209 is fixedly connected to the detection cylinder 1. The connecting block 203 is made of stainless steel and extends through and to the outside of the piston rod 204. The piston rod 204 is slidably connected to the detection cylinder 1. The guide tube 208 extends through and to the outside of the fixed sleeve 206. There are two sets of piston rod 204, fixed sleeve 206 and connecting block 203. There are multiple sets of reset spring 207 and electromagnet 205. The soil moisture meter 201, electromagnet 205, micro air pump 209 and data transmission antenna 210 are electrically connected to the controller 4.

[0028] The working process of this utility model is as follows: When using the real-time detection device for the moisture content of the subgrade compacted material based on the dielectric constant designed in this scheme, the detection cylinder 1 is placed on the subgrade compacted material. Pressing the detection cylinder 1 will cause the probe of the soil moisture meter 201 to be inserted into the soil. The controller 4 starts the soil moisture meter 201, which measures the dielectric constant of the soil and calculates the moisture content based on the measured dielectric constant. The data transmission antenna 210 transmits the data measured by the soil moisture meter 201 to the monitoring center. After the detection is completed, pulling the detection cylinder 1 will cause the soil moisture meter 201 to move upward, pulling the soil moisture meter 201 out of the subgrade compacted material. The controller 4 starts the micro air pump 209, which sends air into the fixed sleeve 206 through the guide pipe 208. The air entering the fixed sleeve 206 will push the piston rod 204 downward. The downward moving piston rod 204 drives the cleaning plate 202 downward through the connecting block 203. The downward-moving cleaning plate 202 scrapes off the soil attached to the probe of the soil moisture meter 201. After cleaning, the cleaning plate 202 moves below the probe of the soil moisture meter 201. The controller 4 turns off the electromagnet 205, and the electromagnet 205 no longer attracts the connecting block 203. The cleaning plate 202 is pulled and removed. The connecting block 203 on the new cleaning plate 202 is aligned with the piston rod 204. The new cleaning plate 202 is pushed and the connecting block 203 on the new cleaning plate 202 is inserted into the piston rod 204. The controller 4 starts the electromagnet 205. The electromagnet 205 attracts the connecting block 203 on the new cleaning plate 202 and installs the new cleaning plate 202 on the piston rod 204. The micro air pump 209 draws air from the fixed sleeve 206 through the guide tube 208. The reset spring 207 drives the piston rod 204 and the new cleaning plate 202 back to their original positions.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
