The PLC 42 is fixedly connected with one side of the fixed seat 1 far away from the water injection pit through a bolt. The electromagnetic valve 43 is provided on the outer peripheral surface of the water pipe 23. The PLC controller 42 is electrically connected to the solenoid valve 43 and the contact switch 41 to form a closed circuit. When the float rod 34 touches the contact switch 41, the contact switch 41 sends an electric signal to the PLC controller 42, the PLC controller 42 sends an electric signal to the electromagnetic valve 43, the flow passage of the electromagnetic valve 43 inside the water pipe 23 is closed, and the water inside the water storage tank 22 cannot flow into the water filling pit. When the floating rod 34 is separated from the contact switch 41, the contact switch 41 sends an electric signal to the PLC controller 42, the PLC controller 42 sends an electric signal to the electromagnetic valve 43, the flow passage of the electromagnetic valve 43 located inside the water pipe 23 is opened, and the water inside the water storage tank 22 flows into the water filling pit through the water pipe 23, so as to ensure that the water level in the water filling pit is not changed. The implementation principle of the above embodiment is as follows: the operator connects the power supply to start the PLC controller 42, the solenoid valve 43, and the contact switch 41.

The operator first places the experimental device above the soil layer, placing the placement frame 31 inside the water injection pit. The operator then pours fresh water into the interior of the storage tank 22. At this time, since the contact switch 41 is not in contact with the float 34, the flow path of the electromagnetic valve 43 located inside the water pipe 23 is opened, and the fresh water inside the water tank 22 flows into the water injection pit through the water pipe 23.

Along with the gradual rising of the horizontal plane in the water injection pit, the horizontal plane drives the kickboard 5 to move upwards, and the kickboard 5 drives the floating rod 34 to move upwards along the straight line direction of the fixed rod 33. When the float lever 34 touches the contact switch 41, the contact switch 41 sends a signal to the PLC controller 42, the PLC controller 42 sends a signal to the electromagnetic valve 43, and the electromagnetic valve 43 receives the signal to close the flow passage of the water pipe 23.

Along with in the inside water infiltration of water injection hole soil, the inside water reduction in water injection hole leads to the inside horizontal plane of water injection hole to reduce, along with the reduction of horizontal plane, because the gravity of kickboard 5 self again, kickboard 5 can drop downwards automatically when not receiving buoyancy to support, kickboard 5.

The floating plate 5 drives the floating rod 34 to move downwards, the floating rod 34 is separated from the contact of the contact switch 41, at the moment, the contact switch 41 sends a signal to the PLC 42, the PLC 42 sends a signal to the electromagnetic valve 43, the electromagnetic valve 43 opens a flow passage of the water service pipe 23, and water flows into the water injection pit through the water service pipe 23.

When the water level inside the water filling pit is restored to the initial height and the float 34 touches the contact switch 41, the water storage tank 22 will not fill the water filling pit.

When the floating rod 34 moves upward, the floating rod 34 first touches the rubber protection block 37, the floating rod 34 continues to move upward, the floating rod 34 drives the rubber protection block 37 to deform, the floating rod 34 touches the contact switch 41, and the rubber protection block 37 prevents the contact switch 41 from contacting water.

The floating rod 34 moves inside the hollow tube 32, and the hollow tube 32 also limits the moving path of the floating rod 34, so that the floating rod 34 is corresponding to the position of the contact switch 41, and when the floating rod 34 moves upwards, the floating rod 34 touches the contact switch 41.

In addition, when water flows in the water through pipe 23, when the water flows out of the water through pipe 23, the water flows firstly touch the splash proof block 6, the impact force of the water flows is relieved, and the water flows into the water injection pit from the water flowing hole 61 of the splash proof block 6.

It is noted that, in the present invention, the model of the electromagnetic valve 43 is: LD51, model number of PLC controller 42 is: s7-2, the model of the contact switch 41 is: a contact switch H4.5; the placement frame 31 is a rectangular parallelepiped without a top cover and a bottom plate.

The operator can derive the permeability of the soil from the amount of water flow reduction within the storage tank 22.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
