[0023] Example 1:
[0024] See also Figures 1 and 2The utility model is a secondary force simulation device for buried pipelines after repair, comprising a three-axis platform 1, a sliding plate 2 is slidably connected to the top of the front-rear moving part of the three-axis platform 1, a detection mechanism 3 is provided at the top right end of the sliding plate 2, a knocking block 4 is fixedly connected to the bottom of the lifting mechanism in the three-axis platform 1, and a rainwater simulation mechanism 5 is fixedly connected to the top of the left-right moving part in the three-axis platform 1;
[0025] The detection mechanism 3 includes a first slide groove 31. The first slide groove 31 is provided at the top right end of the sliding plate 2. Eight groups of first electromagnetic blocks 32 are fixedly connected to the rear end of the first slide groove 31. The first electromagnetic blocks 32 are convenient for driving the sliding block 33 to move.
[0026] A sliding block 33 is slidably connected in the first slide groove 31, and the top of the sliding block 33 is fixedly connected to the bottom of the piston rod in the piston cylinder 34. A solenoid valve 35 is fixedly connected to the delivery port of the connecting pipe at the left end of the piston cylinder 34, which facilitates the control of gas inlet and outlet.
[0027] The left end of the connecting pipe at the left end of the piston cylinder 34 is fixedly connected to an air bag 36, the top of the air bag 36 is fixedly connected to a placement plate 37, and the top of the placement plate 37 is fixedly connected to a second electromagnetic block 38, which facilitates magnetic adsorption of the buried pipeline.
[0028] The first electromagnetic block 32 and the second electromagnetic block 38 are both electrically connected to an external current output device. The first electromagnetic block 32 is magnetically attracted to the sliding block 33 , and the bottom of the airbag 36 is fixedly connected to the top of the sliding plate 2 .
[0029] The working principle of the secondary stress simulation device for buried pipeline repair based on the first embodiment is as follows:
[0030] First, when using this device, first place the device in the working area, then connect the device to an external power source to provide the power required for the device to work;
[0031] Second, the staff places the buried pipeline above the second electromagnetic block 38, and then drives the second electromagnetic block 38 to work through the external current output device, so that the second electromagnetic block 38 magnetically attracts the buried pipeline. When the knocking block 4 knocks on the buried pipeline, the electromagnetic valve 35 is started, and then the buried pipeline is affected by the knocking force to drive the placement plate 37 to move downward, so that the placement plate 37 squeezes the airbag 36, so that the gas in the airbag 36 is transported to the piston cylinder 34 through the connecting pipe at the left end of the piston cylinder 34, and then the piston rod in the piston cylinder 34 moves to the right, and the piston rod in the piston cylinder 34 drives the sliding block 33 to move to the right in the first slide groove 31. Then the staff judges the degree of squeezing of the airbag 36 by observing which group of the first electromagnetic block 32 the sliding block 33 moves to in the first slide groove 31, and thus indirectly judges the knocking force of the knocking block 4, to prevent large deviations in the simulated stress distribution and affect subsequent calculation and analysis results;
[0032] Third, when the airbag 36 needs to be inflated, the eight groups of first electromagnetic blocks 32 are energized step by step through the external current output device, so that the sliding block 33 is affected by the electromagnetic block of the first electromagnetic block 32 and moves to the left. The sliding block 33 drives the piston rod in the piston cylinder 34 to move to the left, so that the gas in the piston cylinder 34 is transported to the airbag 36 through its left end connecting pipe, completing the inflation of the airbag 36.

[0039] In this embodiment:
[0040] When rain simulation is required, the motor 52 is started, and the motor 52 drives the screw 53 to rotate. The movable plate 54 is driven to move backward through the rotation of the screw 53 and the sliding connection between the movable plate 54 and the U-shaped frame 51.
