Description

Technical Field

[0001] The invention belongs to the research field of the collision characteristics between particles and a riser in the process of deep-sea mining, and in particular is a pneumatic deep-sea mining particle rotary launcher. Background Art

[0002] In the field of deep-sea mining technology, there is a general lack of dedicated and controllable particle launch experimental equipment for the study of the collision characteristics of seabed mineral particles and lifting pipes. Traditional research methods mainly rely on two technical routes. The pipeline pumping simulation method directly uses the hydraulic lifting pipe of the mining system to observe particle collisions, but there are problems such as uncontrollable flow rate, large randomness of particle trajectories, and inability to reproduce specific collision parameters, resulting in low confidence in experimental data; the throwing method grabs and ejects particles, but its ejection speed cannot be fixed, the error is large, the angle adjustment accuracy is poor, and it is difficult to control variables to meet the needs of collision experiments.

[0003] There are three key defects in the existing technology in the particle launch experimental device, which seriously limits the simulation research on the collision behavior of particles under deep-sea mining conditions. First, in terms of the control of the initial velocity of particles, it is difficult to achieve fine adjustment with traditional devices. The simple ejection structure usually causes the initial velocity of particles to fluctuate greatly during the launch process, which cannot meet the simulation requirements of different speed conditions. Secondly, in terms of particle size adjustment, the existing equipment often lacks a multi-particle size adaptation mechanism. The particle size used in the experiment is limited, which makes it difficult to cover the complex situation of coarse and fine particles mixed in the actual deep-sea slurry, reducing the representativeness and applicability of the experiment. Third, in terms of collision angle control, due to the lack of adjustable guidance or trajectory control mechanism, the angle of particles during flight is uncontrollable or limited, and it is impossible to achieve a systematic study of collision characteristics under different incident angles. The above three key defects: initial velocity, particle size and collision angle are the core variables that affect particle collision behavior, which directly determine the repeatability and scientific value of the experiment. However, traditional devices have significant deficiencies in all three aspects, resulting in a clear mismatch between experimental conditions and the actual deep-sea mining environment, and making it particularly difficult to carry out variable separation analysis and law exploration, which requires further improvement. Summary of the invention

[0023] The embodiment of the present invention provides a pneumatic deep-sea mining particle rotary launcher, which provides a reliable experimental platform for the optimization design of deep-sea mining systems and the verification of pipeline anti-collision performance by controlling the particle launch speed, particle size and collision angle. The launcher is used to study the particle collision behavior in the riser, analyze its collision characteristics, and propose relevant conclusions based on the experimental results.

[0024] like Figure 1 As shown, a pneumatic deep-sea mining particle rotary launch device includes an air pump 1, a pressure regulating valve 2, a solenoid valve 3, two quick exhaust valves 4, an SC cylinder 5, a particle placement device 6 and an angle adjustment device 7.

[0025] Figure 2 , Figure 3 and Figure 4 Combination Figure 1The air pump 1 is connected to the second air inlet 15 of the pressure regulating valve 2 through a pipeline, and the third air outlet 16 of the pressure regulating valve 2 is connected to the first air inlet 13 of the solenoid valve 3 through a pipeline; the first air outlet 11 of the solenoid valve 3 is connected to the first exhaust end 8 interface of the SC cylinder 5 through a pipeline and a quick exhaust valve 4; the second air outlet 12 of the solenoid valve 3 is connected to the second exhaust end 9 interface of the SC cylinder 5 through a pipeline and a quick exhaust valve 4; and the two quick exhaust valves 4 are arranged on the first exhaust end 8 and the second exhaust end 9 of the SC cylinder 5, which are used to accelerate the exhaust process and quickly release the gas, thereby increasing the flow speed of the air inside the SC cylinder 5 and improving the speed and distance of the particle emission.

[0026] The SC cylinder 5 is installed on the angle adjustment device 7, and the particle placement device 6 is installed on the right end face of the SC cylinder 5. The particle placement device 6 is used to place the particles on the front end of the telescopic rod 10 of the SC cylinder 5. The particle launch is achieved by controlling the extension and retraction of the SC cylinder 5. The movement of the telescopic rod 10 can adjust the initial launch velocity of the particles according to different air pressures, and realize the rotation of the particles by hitting different parts of the particles.

[0027] Specifically, in this embodiment, compressed air is provided by an air pump 1, a pressure regulating valve 2 adjusts the output pressure, a solenoid valve 3 controls the air flow interruption, and an SC cylinder 5 realizes the rapid emission of particles. The telescopic rod 10 of the SC cylinder 5 hits different parts of the particles to generate a rotational motion. The launch device is equipped with a quick exhaust valve 4 to speed up the exhaust speed. The particle placement device 6 is used to place the particles to be launched in front of the telescopic rod 10 to ensure the launch accuracy. The angle adjustment device 7 is used to control the emission direction of the particles to achieve the launch requirements of different collision angles. The device has a simple structure and flexible control, and can be widely used in the research of deep-sea mining particle collision experiments.

[0028] The air pump 1 serves as a power source and provides energy through air compression. The working principle of the air pump 1 is to compress the gas and transmit it to the SC cylinder 5 in a high-pressure state, thereby promoting the particle launch. The function of the SC cylinder 5 is to launch the particles. A telescopic rod 10 is equipped inside the cylinder, and the particle launch is achieved by controlling the expansion and contraction of the cylinder. The movement of the telescopic rod 10 can adjust the initial launch velocity of the particles according to different air pressures, and realize the rotation of the particles by hitting different parts of the particles, that is, the length and moving speed of the telescopic rod 10 of the SC cylinder 5 can be controlled by adjusting the air pressure, thereby controlling the speed of the particle launch.

[0029] The application of the quick exhaust valve 4 makes the gas discharge more rapid, thereby effectively improving the emission efficiency and range of the particles. The quick exhaust valve is used to accelerate the exhaust speed, quickly release the gas, and increase the emission speed and distance of the particles. This design can reduce the lag time of gas release, so that the particles can reach a farther distance. The particle placement device 6 can fix the particles and accurately place them at the emission point of the cylinder telescopic rod through the clamping structure to ensure the stability and accuracy of the position of the particles during the emission process. The particle placement device 6 can adapt to particles of different sizes and shapes, and can cooperate with the cylinder telescopic rod. The angle adjustment device 7 can adjust the emission angle in the horizontal plane and the vertical plane respectively, and is used to adjust the emission angle of the particle placement device 6, so as to realize the emission of particles at different collision angles. The emission angle of the particles can be changed according to the experimental requirements to simulate different collision angles and analyze the motion trajectory and collision behavior of the particles at different angles.

[0030] The pressure regulating valve 2 is arranged in the air path between the air pump 1 and the solenoid valve 3, the second air inlet 15 of the pressure regulating valve 2 is connected to the air pump 1, the third air outlet 16 of the pressure regulating valve 2 is connected to the first air inlet 13 of the solenoid valve, and a knob 14 is arranged on the top of the pressure regulating valve 2, which is used to adjust the pressure of the gas flowing into the SC cylinder 5. The pressure regulating valve 2 controls the emission speed of the particles by adjusting the pressure value to meet different experimental requirements. By adjusting the pressure regulating valve 2, the particle emission speed can be accurately controlled, so that the particles are emitted at different speeds and produce different motion trajectories under different pressures, which is suitable for a variety of experimental conditions.

[0031] The solenoid valve 3 is arranged in the gas circuit, and is used to control the on and off of the compressed air, and is used to accurately control the flow direction of the airflow, so as to ensure that the particle launch device can launch particles according to the predetermined parameters and time. The solenoid valve 3 can realize the rapid start and stop of the cylinder, and the first air inlet 13 of the solenoid valve 3 is connected to the third air outlet 16 of the pressure regulating valve 2, and the first air outlet 11 and the second air outlet 12 of the solenoid valve 3 are respectively connected to the first exhaust end 8 and the second exhaust end 9 interface of the SC cylinder 5. The solenoid valve 3 is located between the pressure regulating valve 2 and the SC cylinder 5, and cooperates with the pressure regulating valve 2 and the solenoid valve 3. The solenoid valve 3 can accurately control the launch time of the particles, so that the entire launch process can be flexibly adjusted, and can be timed controlled or remotely operated.

[0032] The telescopic rod 10 of the SC cylinder 5 can achieve the rotational movement of the particles by hitting different positions of the particles. By hitting different parts of the particles with the telescopic rod 10, the particles can produce a rotation effect while being launched, which is of great significance for studying the collision behavior of particles in deep-sea mining experiments.

[0033] The quick exhaust valve 4 is a quick exhaust valve with a quick exhaust function, which increases the speed and distance of the emitted particles. The quick exhaust valve 4 is used to avoid the gas from being discharged through the pipeline, so that the gas is directly discharged into the air, thereby exhausting more quickly and effectively improving the emission efficiency and range of the particles.

[0034] The particle placement device 6 is used to place the particles in front of the telescopic rod 10 to ensure that the particles can accurately enter the launch position. The particle placement device 6 has a replaceable positioning slot structure, which is suitable for placing particles of different sizes or shapes. By adjusting the size or shape of the slot of the particle placement device 6, it is ensured that the particles can be accurately hit by the telescopic rod 10 before launching.

[0035] like Figure 1 and Figure 5 As shown, the angle adjustment device 7 includes a plurality of telescopic legs 17, a frame platform 18, a connecting pipe 19 and a support bar 20. The tops of the plurality of telescopic legs 17 are connected to the connecting pipe 19 through the frame platform 18, the bottom of the connecting pipe 19 is hinged to the middle of the telescopic legs 17 through the support bar 20, and the SC cylinder 5 is fixedly installed on the top of the connecting pipe 19.

[0036] The launch device is installed as a whole on a rigid base, and the bottom of the rigid base is equipped with a vibration-damping pad to reduce the impact vibration caused by the movement of the SC cylinder 5. This design can effectively reduce the impact of the vibration generated during the cylinder movement on the experimental results, ensure the stability of particle launch, and improve the reliability of experimental data.

[0037] Precisely adjust and control the particle emission parameters. Specifically: adjust the pressure regulating valve to control the pressure of the gas in the SC cylinder, thereby controlling the particle emission speed. When adjusting the pressure, the greater the gas pressure, the higher the particle emission speed, and vice versa. The solenoid valve plays a role in accurately controlling the airflow during the particle emission process. By adjusting the switch state of the solenoid valve, the direction and rate of gas flow inside the cylinder can be accurately controlled, thereby affecting the timing of particle emission. The design of the angle adjustment device enables the cylinder to adjust the particle emission angle during the emission process. The device can achieve precise angle adjustment through an electric drive system to ensure that the angle of particle emission can be adjusted from 0° to 90° to meet the needs of different collision experiments. Control the rotation of the particle by controlling the contact point between the telescopic rod and the particle. The telescopic rod of the SC cylinder realizes the rotation emission of the particle by hitting different parts of the particle. When the telescopic rod of the cylinder moves, the contact position of the particle is different, and the collision angle is also different, resulting in the effect of particle rotation. Check the key parameters of the main components such as the cylinder, air pump, pressure regulating valve, solenoid valve, quick exhaust valve, etc. to ensure that the equipment can operate normally without leakage or mechanical jamming. During the test, the accuracy and stability of particle launch also need to be analyzed to ensure that the distance, speed and rotation angle of particle launch meet the predetermined requirements under different experimental conditions. During the experiment, the launch angle, speed and particle rotation are adjusted according to different experimental conditions, and the experimental data are recorded in real time. Through data analysis, the performance and parameter settings of the launch device are further optimized to better simulate the particle collision characteristics in the actual deep-sea mining environment.

[0038] The present invention provides a method for using a pneumatic deep-sea mining particle rotary launcher, which specifically comprises the following steps:

[0039] Step 1, design and assemble a pneumatic deep-sea mining particle rotation launcher. First, the present invention is a multifunctional launch system composed of an air pump 1, a pressure regulating valve 2, a solenoid valve 3, two quick exhaust valves 4, an SC cylinder 5, a particle placement device 6 and an angle adjustment device 7; the air pump 1 provides compressed gas to drive the telescopic rod 10 in the SC cylinder 5 to move. The telescopic rod 10 of the SC cylinder 5 realizes the launch of particles by contacting with particles, and controls the rotation of particles according to different positions of the impact particles. By controlling the output pressure by the pressure regulating valve 2, the SC cylinder 5 can launch particles with different initial velocities to simulate the collision behavior of particles and pipelines during deep-sea mining. At the same time, the quick exhaust valve 4 is used to accelerate gas discharge and increase the speed of particle launch. The solenoid valve 3 is used to control the launch time of the particles, the particle placement device 6 can accurately place the particles in front of the telescopic rod 10 of the SC cylinder 5, and the angle adjustment device 7 allows the particles to be launched at different angles.

[0040] Step 2, adjust the parameters of the pneumatic deep-sea mining particle rotation launcher. First, adjust the working pressure of the air pump 1, and adjust the pressure regulating valve 2 as needed to control the pressure of the airflow to ensure that the particles can be launched at the set initial velocity. Adjust the angle of the angle adjustment device 7 to ensure that the particles can be launched at different collision angles. The particle placement device 6 ensures that the particles can be correctly placed in front of the telescopic rod 10 of the SC cylinder 5 to avoid improper placement of particles. Before each launch experiment, adjust the parameters of all equipment to meet different experimental requirements. Through these steps, the launch speed, angle and rotation of the particles can be controlled to simulate the collision characteristics of particles and pipelines in actual deep-sea environments.

[0041] Step 3, carry out the experiment and data collection of particle rotation emission. In order to realize the particle rotation emission, it is necessary to control the impact position of the telescopic rod 10 of the SC cylinder 5 and the particle so that the particle rotates during the emission process. The impact particle center is slightly above for upward rotation, and the impact particle center is slightly below for downward rotation. During the experiment, the initial velocity of the particle emission is changed by controlling the pressure output by the air pump 1, and the angle adjustment device 7 is adjusted to realize the emission of particles at different collision angles. Under the control of the telescopic rod 10 of the SC cylinder 5, the particles will be launched into a predetermined target area, and the emission speed, angle and rotation angle of the particles will be recorded. A high-speed camera is used to capture the trajectory and motion state of the particles, and the motion trajectory of the particles is analyzed by image processing technology to extract parameters such as the velocity and rotation angle of the particles.

[0042] Experimental results show that in the test, by adjusting the different settings of the pressure regulating valve 2, the quick exhaust valve 4 and the solenoid valve 3, the initial velocity of the particles can be accurately controlled from 0.5m / s to 5m / s, and the rotation angle and collision angle of the particles can also be adjusted from 0° to 90° through the angle adjustment device. The experimental data are obtained through high-precision sensors and image recognition technology, which provide strong support for the subsequent research on particle collision characteristics of deep-sea mining systems.

[0043] As described above, the pneumatic deep-sea mining particle rotating launch device of the present invention can provide a stable, controllable and precise experimental platform for the study of the collision characteristics of deep-sea mining particles and pipelines, solving the problems of insufficient particle launch accuracy and difficulty in simulating deep-sea environment in the prior art, and providing reliable data support for the optimization design and anti-collision performance verification of deep-sea mining systems.
