Description

Technical Field

[0001] The utility model belongs to the technical field of seismic exploration, in particular to a seismic exploration simulation experimental device. Background Art

[0002] Seismic exploration is an important means of surveying oil and natural gas resources before drilling. It is also widely used in coalfield and engineering geological exploration, regional geological research and crustal research. Seismic exploration uses the differences in elasticity and density of underground media to infer the properties and morphology of underground rock formations through observation and analysis.

[0003] Most of the existing earthquake exploration simulation experimental devices insert simulation boards of different soil or rock layers into a simulation box, then irradiate the simulation inward through a wave frequency generator above it, and then install wave frequency sensing lights on the side walls of the box to visually observe earthquakes by observing the changes in light. However, most of the simulation boards of different soil or rock layers in the existing earthquake exploration simulation experimental devices are directly inserted into the box without any limiting devices. Therefore, they may slip out and fall during actual use or transportation, thereby causing damage to them.

[0004] For example, the existing Chinese patent publication number is: CN211236266U, a seismic exploration simulation experimental device, including a box, a wave frequency transmitter and three simulation boxes; the interior of the box is divided into three simulation box spaces from top to bottom by two partitions, the top surface of the partition and the bottom surface of the inner wall of the box are both slidably connected with pulleys, and the front and back surfaces of the inner wall of the box are fixedly connected with slide rails in each simulation box space.

[0005] It can be seen that the patent documents cited above also have the same problem. Although the device can simulate different rock environments by changing the position between the simulation boxes and the height of different simulation boxes, the tempered glass allows people to directly observe the distribution of rock layers in the box, and the indicator light can gradually change with the emission of the wave frequency, and the simulation results are closer to reality and more intuitive. However, the multiple simulation boxes in the device are all slidably plugged into the box, so there is a risk of slipping out and falling during transportation or use, thereby causing damage to them.

[0006] The utility model aims to provide a seismic exploration simulation experimental device to solve the problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a seismic exploration simulation experiment device, comprising a box for installing the seismic exploration simulation experiment device, a soil layer simulation plate is fixedly connected to the upper part of the interior of the box, a telescopic cylinder is fixedly connected to the outer wall of the box, an L-shaped plate is slidably connected in the telescopic cylinder, a wave frequency generator is fixedly connected to the lower end of the L-shaped plate, a plurality of rectangular holes are opened on the side wall of the box, rectangular blocks are clamped in the rectangular holes, a geological layer simulation plate is fixedly connected to one end of the rectangular block close to the interior of the box, a cavity is opened in the rectangular block, and the cavity A push plate is symmetrically and slidably connected inside, and a winding roller is connected to the cavity for transverse rotation. The two push plates are fixedly connected to the side away from the winding roller. A plurality of through holes are provided on the side wall of the rectangular block. The insert rod slides through the through holes and extends to the outside of the rectangular block. A pull rope is fixedly connected to the opposite side of the two push plates, and the two pull ropes are fixedly connected to the winding roller. A spring is slidably sleeved on the rod wall of the insert rod, and one end of the spring is fixedly connected to the push plate, and the other end is fixedly connected to the inner wall of the cavity. The inner wall of the rectangular hole is symmetrically provided with card slots, and the insert rod is inserted into the inside of the card slot.

[0008] Preferably, the rotating shaft of the winding roller rotates and extends to the outside of the rectangular block and is fixedly connected to a rotating rod.

[0009] Preferably, a limiting block is symmetrically fixedly connected to the rod wall of the insertion rod, and a limiting groove is symmetrically provided in the through hole provided on the side wall of the rectangular block.

[0010] Preferably, the two limiting blocks are slidably connected to the inside of the two limiting grooves respectively.

[0011] Preferably, fixing blocks are symmetrically fixedly connected to the side walls of the two push plates, and strip grooves are symmetrically opened on the inner wall of the cavity.

[0012] Preferably, the two fixing blocks are slidably connected to the inside of the two strip grooves respectively.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The earthquake exploration simulation experimental device, when it is necessary to install the rectangular block and the geological layer simulation plate, first the geological layer simulation plate is plugged into the inside of the rectangular hole, when the rectangular block is close to the rectangular hole, first the rotating rod is rotated to drive the winding roller fixedly connected to it to rotate, and the pull ropes on the two push plates are wound by the winding roller, and at the same time the two push plates and the plugging rods on the push plates are retracted into the cavity in the rectangular block by the pull ropes, and at the same time the spring is stretched until the plugging rod is retracted into the cavity, and then the rectangular block is continued to be pushed, when the plurality of plugging rods are relatively parallel to the slots on the inner wall of the rectangular hole, the spring will pull the push plate to restore to the initial state after the rotating rod is released, and at the same time the plugging rod is pushed by the push plate to be plugged into the inside of the slot, so as to fix and limit the rectangular block and the geological layer simulation plate, thereby preventing them from slipping during transportation, and when it is necessary to disassemble them, only the rotating rod needs to be rotated again to drive the plugging rod to retract into the cavity again until the plugging rod is moved out to the inside of the slot, and at this time the rectangular block and the geological layer simulation plate can be pulled out. Compared with the prior art, the device can effectively fix the rectangular blocks and the geological layer simulation plate, and is convenient for disassembly, thereby effectively preventing the geological layer simulation from slipping out and falling and causing damage.

The two push plates 10 are fixedly connected with pull ropes 12 on the opposite sides, and the two pull ropes 12 are fixedly connected to the winding roller 13. The rotating shaft of the winding roller 13 rotates and extends to the outside of the rectangular block 8 and is fixedly connected with a rotating rod 14.

[0028] How it works

[0029] When the earthquake exploration simulation experimental device is used, the geological layer simulation plate 9 is first inserted into the rectangular hole 6 provided on the side wall of the box body 1. When the rectangular block 8 is close to the rectangular hole 6, the rotating rod 14 is first rotated to drive the winding roller 13 fixedly connected thereto to rotate, and the pulling rope 12 on the two push plates 10 is wound by the winding roller 13. At the same time, the two push plates 10 and the insertion rod 11 on the push plates 10 are retracted into the cavity in the rectangular block 8 by the pulling rope 12, and the spring 15 is stretched at the same time until the insertion rod 11 is retracted. It shrinks into the cavity, and then continues to push the rectangular block 8 to move into the rectangular hole 6. When the multiple insertion rods 11 are relatively parallel to the slots on the inner wall of the rectangular hole 6, the spring 15 will pull the push plate 10 to return to its initial state after releasing the rotating rod 14. At the same time, the push plate 10 pushes the insertion rod 11 to be inserted into the slots, so as to fix and limit the rectangular block 8 and the geological layer simulation board 9 to prevent them from slipping during transportation. Then, the wave frequency generator 5 can be used to emit wave frequencies into the box 1, and the earthquake situation can be observed through the lights on the side walls of the box 1.
