DETAILED DESCRIPTION

[0021] The embodiment of the utility model will be further described in detail below in combination with the drawings and examples, and the following examples are used to illustrate the technical scheme of the utility model, but cannot be used to limit the protection scope of the utility model.

[0022] Embodiment:

[0023] As Figure 1 , Figure 2 shown, the utility model provides a kind of simulation device for regulating and controlling sludge stratum shield floating, including support 1, control box 4 is arranged in one side of support 1, control box 4 is equipped with transmission assembly inside, and the transmission assembly plays a role in entire system, and the inside of support 1 is placed model box 7, and simulation assembly is arranged in model box 7, and simulation assembly is connected with transmission assembly, and both work cooperatively, ensure the operation of system, on the same side of support 1, pressure barrel 3 and slurry barrel 2 are also arranged, and pressure barrel 3 is connected with simulation assembly and slurry barrel 2 by conduit, and such connecting mode makes slurry be able to be transported to simulation assembly by conduit under the action of pressure barrel 3, carries out corresponding simulation operation, and the cooperation between each component provides guarantee for the operation of entire system.

[0024] As Figure 2 , Figure 3The transmission assembly mainly includes a screw rod 12, which is arranged in the model box 7. At one end of the model box 7, a screw rod fixing seat 8 is arranged, and a bearing is arranged on the screw rod fixing seat 8. One end of the screw rod 12 is clamped in the bearing. Inside the model box 7, a pushing plate 17 is further arranged. After passing through the model box 7, the one end of the screw rod 12 is sleeved with a second gear 13. The pushing plate 17 is parallel to the second gear 13 and is sleeved on the screw rod 12. The pushing plate 17 is in contact with one end of the simulation assembly. When the transmission assembly starts to work, the screw rod 12 starts to rotate under the drive of the second gear 13. Since the pushing plate 17 is sleeved on the screw rod 12, with the rotation of the screw rod 12, the pushing plate 17 will move along the axial direction of the screw rod 12. This movement can generate a pushing force on one end of the simulation assembly, so as to promote the simulation assembly to perform corresponding actions. The screw rod fixing seat 8 provides support for the screw rod 12, and the bearing reduces the friction of the screw rod 12 during rotation. The parallel arrangement of the pushing plate 17 and the second gear 13 and the combination with the screw rod 12 play a role in the system.

[0025] The transmission assembly further includes a motor pad 15 and a motor 18. The motor pad 15 is inside the control box 4 and is installed on the support 1. The motor pad 15 provides a mounting basis for the motor 18, ensuring that the motor 18 does not shake or displace during operation. The motor 18 is installed on the motor pad 15 to achieve optimal cooperation with other transmission components. The shaft end of the motor 18 is sleeved with a first gear 14. The first gear 14 is connected to the second gear 13 through a belt 19, which can effectively transmit power between the two gears. When the motor 18 starts, the shaft of the motor 18 drives the first gear 14 to rotate. Since the first gear 14 is connected to the second gear 13 through the belt 19, the rotation of the first gear 14 will be transmitted to the second gear 13 through the belt 19, thereby causing the second gear 13 to start rotating. The rotation of the second gear 13 further drives the screw rod 12 to rotate, thereby pushing the pushing plate 17 to move, realizing the transmission effect on the simulation assembly. During the entire transmission process, the motor pad 15, the motor 18, the first gear 14, the belt 19 and the second gear 13 cooperate with each other to form a transmission system.

[0026] As Figure 2 , Figure 4As shown, the simulation component mainly consists of a model shell 6, which is fitted onto the spiral rod 12. Inside the model shell 6, multiple sets of pipe segments 10 are installed. These pipe segments 10 are spliced ​​together to form a long cylindrical structure. The splicing design of multiple sets of pipe segments 10 allows the simulation component to better simulate the pipe structure in actual engineering. Multiple sets of sealing rings 21 are installed between the multiple sets of pipe segments 10. The presence of the sealing rings 21 effectively prevents liquid leakage. In addition, multiple sets of laser rangefinders 20 (such as S656501L laser rangefinders) are installed inside the multiple sets of pipe segments 10. The laser rangefinders 20 can measure the distance and position changes inside the pipe segments 10. Inside the model shell 6, a fixed tube 11 is also installed. The fixed tube 11 is also fitted onto the spiral rod 12. Multiple sets of total reflection prisms 16 are installed on the fixed tube 11.

[0027] Inside the model shell 6, a rubber ring 9 is provided. This rubber ring 9 is fitted over multiple sets of tube segments 10 and is located between the tube segments 10 and the model shell 6. It can play a buffering role. When the model is subjected to external impact or vibration during operation, the rubber ring 9 can absorb some energy, thereby protecting the tube segments 10 and the model shell 6 from damage. The rubber ring 9 can also enhance the sealing performance and prevent external impurities or liquids from seeping into the tube segments 10. Multiple sets of pulleys 22 are provided on the rubber ring 9. These pulleys 22 are in contact with the model shell 6 and the tube segments 10. They can reduce the friction between the tube segments 10 and the model shell 6.

[0028] Inside the model shell 6, a rubber sealing brush 23 is also provided. The outer diameter of the rubber sealing brush 23 is equal to the inner diameter of the model shell 6, ensuring that the rubber sealing brush 23 can be locked inside the model shell 6. The rubber sealing brush 23 contacts the push plate 17. When the push plate 17 moves under the action of the transmission component, the rubber sealing brush 23 can prevent external impurities from entering the model and also prevent the material inside the model from leaking out, ensuring the reliability of the simulation process. Multiple sets of notches are opened on the rubber ring 9, and the conduit can pass through these notches and extend into the model shell 6. One end of the conduit is connected to the simulation component inside the model shell 6, and the other end is connected to the pressure tank 3. The material in the pressure tank 3 can be transported into the model shell 6 through the conduit when needed to participate in the simulation process.

[0029] like Figure 2 , Figure 3 As shown, the control box 4 is connected to the bracket 1 by bolts. On the control box 4, there is a switch 5. This switch 5 plays a control role. It is electrically connected to the motor 18. When the operator presses the switch 5, the current will be conducted to the motor 18 through the connection line, thereby starting the motor 18 and making it start running, driving the entire transmission assembly to work, and then driving the simulation assembly to perform the corresponding simulation operation.

[0030] The specific use mode and role of the embodiment:

[0031] The user first puts the soil into the model box 7, then the user opens the switch 5 of the control box 4, the motor 18 starts to rotate, the rotation of the motor 18 drives the first gear 14 to rotate, the second gear 13 is connected with the first gear 14 through the belt 19, under the driving of the first gear 14, the second gear 13 also starts to rotate at the same time, with the rotation of the gear, the advancing plate 17 starts to move forward slowly, the advancing plate 17 pushes the simulation assembly to move in the process of movement, the model shell 6 and the pipe piece 10 are installed in the simulation assembly, under the action of the advancing plate 17, the pipe piece 10 gradually exposes the model shell 6; The slurry in the slurry barrel 2 flows into the gap between the pipe piece 10 and the model shell 6 under the action of the pressure barrel 3; In order to more conveniently measure the displacement of each pipe piece 10, the total reflection prism 16 is installed on the fixed pipe 11 corresponding to the position of the pipe piece 10, in the subsequent measurement work, the total reflection prism will always be aligned with the corresponding laser range finder 20, so that the data collection and arrangement are greatly facilitated, and the work efficiency is effectively improved.
