When in use, in the first step, as shown in fig. 1-5, oil used in an experiment is added into the oil storage bin 101, and the oil return valve 403 is opened to ensure that gas in the device can be smoothly discharged in the oil adding process; because the oil storage bin 101 is communicated with the oil groove 1021 in the transmission case 102, oil enters the oil groove 1021; because the sealing ring 104 is arranged at one end of the transmission case 102, the transmission shaft 103 is rotationally connected with the sealing ring 104, the sealing effect of the oil groove 1021 is realized, and the oil liquid is ensured not to leak in the experimental process; as the oil in the oil groove 1021 increases, the oil flows into the first oil passage 2045 communicated with the oil inlet 2044 on the oil feed rod 2052;

one end of the first spring 2048 is fixedly connected with the fixed sleeve 2049, the other end of the first spring is fixedly connected with the first top ball 2050, and the diameter of the first top ball 2050 is larger than that of the first oil duct 2045 and smaller than that of the second oil duct 2051; therefore, when the first spring 2048 in the natural state is in this state, the first top bead 2050 completely blocks the first oil passage 2045; when oil continues to be added, the oil pressure in the first oil passage 2045 increases; at this time, the oil presses the first spring 2048 to contract by pressing the first top bead 2050; when the first spring 2048 contracts, the first top ball 2050 is driven to move, and oil flows into the second oil duct 2051; because the first oil through hole 2054 on the first positioning column 2053 penetrates through the fixed sleeve 2049, the oil continues to flow into the slideway 203 from the second oil passage 2051;

because the third oil duct 3011 is internally threaded with the spacer sleeve 302, the middle of the spacer sleeve 302 is provided with the second oil passage hole 3021; when the second spring 304 is in a natural state, the second oil passing hole 3021 is completely blocked by the second knock bead 303; similarly, the oil presses the second spring 304 to contract by pressing the second top bead 303; when the second spring 304 contracts, the second top ball 303 is driven to move, and oil flows into the third oil duct 3011 and flows into a fourth oil duct 3012 communicated with the third oil duct 3011;

with the increase of oil in the fourth oil duct 3012, the oil pressure of the slide ways 203 and the third oil duct 3011 on the two sides of the second top ball 303 is smaller and smaller, and the second spring 304 is changed from a contraction state to an extension state; when the second spring 304 extends, the second ejecting ball 303 is driven to move until the second ejecting ball 303 completely blocks the second oil passing hole 3021; at the moment, oil in the slide way 203 starts to increase, and similarly, the oil pressure of the first oil passage 2045 and the second oil passage 2051 on two sides of the first top ball 2050 is smaller and smaller, and the first spring 2048 is changed from a contraction state to an extension state; when the first spring 2048 extends, the first top bead 2050 is driven to move until the first top bead 2050 completely blocks the first oil passage 2045;

and stopping adding the oil liquid when the oil liquid level in the oil storage bin 101 reaches the experimental requirement.

Step two, as shown in fig. 1-5, when the motor 6 is started, the shaft head of the motor 6 drives the transmission shaft 103 connected with the shaft head to rotate through the coupling 5; a fixed shaft 1034 at one end of the transmission shaft 103 is connected with the middle part of the pressurizing case 201 in a rotating way; the boss 1032 at the middle part of the transmission shaft 103 is connected with the bearing 105 in the transmission case 102 in a rotating manner, so that the transmission shaft 103 is stably connected, and the stability and safety of the device during operation are ensured; when the transmission shaft 103 rotates, the swash plate 1033 is driven to synchronously rotate;

because the reset spring 2046 is arranged in the positioning hole 202 on the pressurizing case 201, the oil feed rod 2052 in the reset spring 2046 is matched with the slide way 203 in a rotating shaft way; one end of the guide block 2041 is in friction fit with the swash plate 1033, and the guide groove 2042 at the other end is in friction fit with the spherical surface of the movable shaft 2043 on the oil feed rod 2052; along with the rotation of the swash plate 1033, the contact surface between the guide block 2041 and the swash plate 1033 is changed from a low point to a high point, at the moment, the guide block 2041 drives the oil feeding rod 2052 to move through the guide groove 2042, and the limit table 2047 on the oil feeding rod 2052 synchronously moves and compresses the return spring 2046 to contract; when the contact surface of the guide block 2041 and the swash plate 1033 is the highest point, the oil feed rod 2052 stops moving; the swash plate 1033 continues to rotate, the contact surface between the guide block 2041 and the swash plate 1033 is changed from a high point to a low point, at the moment, the return spring 2046 begins to extend, the oil supply rod 2052 is driven to displace through the limiting table 2047, and meanwhile, the oil supply rod 2052 supports one end of the guide block 2041 through the guide groove 2042 and is always attached to the swash plate 1033; when the contact surface of the guide block 2041 and the swash plate 1033 is the lowest point, the oil feed rod 2052 stops moving; in conclusion, along with the transfer of the turntable, the oil feed rod 2052 makes a reciprocating linear motion in the slide 203;

because a plurality of oil feed rods 2052 are arranged in the pressurizing case 201, as the swash plate 1033 rotates, when one part of the oil feed rods 2052 moves along with the fact that the contact surface between the guide block 2041 and the swash plate 1033 changes from a low point to a high point, the other part of the oil feed rods 2052 moves along with the fact that the contact surface between the guide block 2041 and the swash plate 1033 changes from a high point to a low point;

when a part of the oil feed rod 2052 moves along with the 'the contact surface between the guide block 2041 and the swash plate 1033 changes from a low point to a high point', the oil feed rod 2052 linearly moves in the slide way 203 in the direction of compressing the return spring 2046; at this time, the oil in the second oil passage 2051 and the slide 203 is compressed, and pressure is generated to force the first top ball 2050 to completely block the first oil passage 2045, and simultaneously, the second top ball 303 is squeezed to press the second spring 304 to contract; at this time, oil in the second oil passage 2051 and the slide 203 flows into the third oil passage 3011, the oil in the third oil passage 3011 is increased, and the oil pressure is increased;

meanwhile, the other part of the oil feeding rod 2052 moves along with the fact that the contact surface between the guide block 2041 and the swash plate 1033 is changed from a high point to a low point, and the oil feeding rod 2052 linearly moves in the extension direction of the return spring 2046 in the slide way 203; at this time, the oil pressure in the second oil passage 2051 and the slide 203 is reduced, and the oil in the first oil passage 2045 generates pressure to press the first top ball 2050 to displace, so as to press the first spring 2048 to contract; at this time, the oil in the first oil passage 2045 flows into the second oil passage 2051 and the slide 203; in addition, at this time, the second tip bead 303 opposing thereto is affected by the increase of the oil in the third oil passage 3011, so that the second tip bead 303 completely blocks and completely blocks the second oil passage hole 3021.

In summary, the swash plate 1033 rotates to drive the oil supply rod 2052 to supply oil to the third oil passage 3011 in the oil discharge assembly 3, so that oil in the fourth oil passage 3012 in the oil discharge assembly 3 is more and more, and the oil pressure is increased; the oil flows along the oil pipe 404 through the oil discharge port under the action of oil pressure, and presses the air in the device to be discharged through the exhaust valve of the ground hole, so that the test safety is ensured; oil continuously flows back to the oil storage bin 101 through the oil pipe 404, so that the oil is recycled, and waste is avoided; at this time, the pressure value on the pressure gauge 401 is read; the motor 6 drives the transmission shaft 103 to rotate the swash plate 1033, so that the oil feeding rod 2052 is driven to supply oil to the oil discharging assembly 3, and the experimental effect of simply, conveniently and quickly simulating the oil reservoir pressure is achieved.
