Description

Technical Field

[0001] The present invention belongs to the technical field of deep - sea mining equipment, and specifically relates to a deep - sea mining particle collision and launching device for underwater operation. Background Art

[0002] In the field of deep - sea mining technology, for the research on the collision characteristics of seabed mineral particles and the lifting pipeline, there is currently a general lack of dedicated and controllable particle emission experimental equipment. Traditional research methods mainly rely on two technical routes. The pipeline pumping simulation method directly uses the hydraulic lifting pipeline of the mining system to observe particle collisions, but there are problems such as uncontrollable flow velocity, large randomness of particle trajectories, and inability to reproduce specific collision parameters, resulting in low confidence in experimental data; the throwing method grabs and throws particles through an underwater manipulator, with poor angle adjustment accuracy and difficulty in meeting research requirements.

[0003] The existing technology has insufficient parameter control accuracy. It is difficult for traditional devices to achieve fixed and adjustable initial particle velocities, resulting in a significant mismatch between experimental conditions and the actual mining environment. Secondly, there are shortcomings in underwater adaptability. The pressure - resistant performance of traditional sealing structures is insufficient, prone to seal failure or mechanical jamming. In addition, the disordered particle trajectories caused by open - type launching have large lateral deviations, making it difficult to effectively capture collision characteristics. These technical bottlenecks jointly restrict the optimization and verification process of deep - sea pipeline anti - collision design.

[0004] Therefore, it is necessary to develop an underwater particle collision and launching device that can operate stably underwater and support multi - parameter regulation, providing a reliable experimental platform for studying particle collision behavior in the lifting pipe.

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0025] The embodiment of the present invention is an underwater particle launcher based on the collaborative drive of dual motors. It solves the problem of studying the collision characteristics of particles in traditional deep-sea mining without corresponding launch equipment through a high-speed reverse friction wheel group, a slide rail particle size adaptation mechanism and an angle adjustment system. The collision behavior of particles in the lifting tube is experimentally studied, and its collision characteristics are systematically analyzed to put forward relevant conclusions.

[0026] like Figure 1As shown in the figure, an embodiment of the present invention provides a deep - sea mining particle collision and emission device for underwater work, which includes a high - speed dual - drive module, a particle size adjustment module, a particle placement module, and an angle control module. The high - speed dual - drive module includes a 220V power supply 6, two speed regulators 7, two waterproof motors 1, and two friction wheels 2. The 220V power supply 6 is electrically connected to the two waterproof motors 1 through the two speed regulators 7 respectively. The output shafts of the two waterproof motors 1 are tightly connected with the two friction wheels 2, so that the friction wheels 2 have a more stable power output during operation, and at the same time, the contact efficiency between its surface and the particles is improved. The two friction wheels 2 are symmetrically distributed reverse - rotating friction wheels. The particle size adjustment module includes a linear slide rail 3. The two waterproof motors 1 are installed on the linear slide rail 3, and the adaptation for the emission of particles with a particle size of 5 - 50mm is achieved by adjusting the distance between the two waterproof motors 1. The particle placement module includes a particle placement groove 5. The particle placement groove 5 is arranged to align with the engagement area of the two friction wheels 2. This design ensures that the particles can accurately enter the emission area, improves the reliability and efficiency of the system, and uses the self - weight of the particles to achieve natural sliding, ensuring that the particles smoothly enter the emission area. The angle control module includes a rotatable bracket 4. The linear slide rail 3 is fixed on the rotatable bracket 4. The rotation adjustment range of the rotatable bracket 4 is 0° - 90°, which is used to adjust the emission angle of the two friction wheels 2. The selection of the inclination angle can be optimized according to actual needs to adapt to particles of different sizes and shapes.

[0027] As Figure 1 and Figure 4 shown, in the high - speed dual - drive module, the two waterproof motors 1 are waterproof motors with a rotational speed of 3000 - 8000r / min, and are installed on both sides of the device. Two symmetrically distributed reverse - rotating friction wheels 2 are installed on the output shafts of the two waterproof motors 1. The surface of the friction wheel 2 is specially treated with spiral grooves to increase the friction force, ensuring that the particles can be efficiently emitted from the engagement area of the friction wheel. The purpose of increasing the friction force is to enhance the stability and persistence of the force on the particles in the device, prevent them from slipping or shifting during contact, so that the particles can obtain a greater linear velocity when passing through the friction wheel 2, thus realizing a more efficient and stable emission process. This structural design effectively improves the adaptability of the device in complex environments such as high humidity and high pressure, and is an important part for realizing the precise and rapid emission of particles in deep - sea or special environments.

[0028] The rotation speeds of two waterproof motors 1 are adjusted by two independent speed governors 7 to achieve continuously adjustable initial particle velocity. The output shaft of the waterproof motor 1 adopts a composite sealing structure, which can effectively block the intrusion of water under high-speed rotation conditions. The two waterproof motors 1 in this embodiment adopt a closed-loop control system, and the encoder is used to feedback the motor rotation speed in real time to ensure that the two waterproof motors 1 can operate synchronously, thereby improving the firing accuracy and stability of the entire launch system. In order to adapt to various complex working environments, the output shafts of the two waterproof motors 1 adopt a composite sealing structure, including multiple layers of rubber sealing rings and mechanical seals, which can effectively prevent the intrusion of water and other impurities, and ensure the reliability and long life of the module under harsh conditions.

[0029] As Figure 1 and Figure 3 shown, in the particle size adjustment module, the linear slide rail 3 is made of corrosion-resistant stainless steel, has excellent corrosion resistance, and is suitable for various harsh working environments. A ball screw drive mechanism is arranged inside the linear slide rail 3, and the ball screw drive mechanism is driven by a servo motor to realize the bidirectional synchronous movement of the linear slide rail 3 on the cross beam of the rotatable bracket 4. The ball screw drive mechanism in this embodiment has the characteristics of high precision, low friction and long life, ensuring the smooth operation and high-precision adjustment of the linear slide rail. The waterproof motor 1 is fixed on the movable seat of the linear slide rail 3, and the distance between the two motors is adjusted to adapt to particles of different particle sizes. Scale marks are provided on the surface of the linear slide rail 3, which cooperate with a laser distance sensor to form a closed-loop adjustment system, ensuring that the particle size control accuracy is ±1 mm, which is convenient for operators to directly read and adjust the motor distance. Antirust oil is regularly injected into the linear slide rail 3 to ensure that the linear slide rail 3 remains smooth during long-term operation, effectively reducing the wear of the slide rail, extending its service life, reducing maintenance costs, and the antirust oil also has good rust prevention performance, further enhancing the corrosion resistance and reliability of the linear slide rail 3.

[0030] In the angle control module, the rotatable bracket 4 is made of a lightweight titanium-aluminum alloy frame, which has the advantages of high strength and low weight, is suitable for application scenarios that require high precision and lightness, ensures that the angle positioning deviation is less than 1°, and provides high-precision angle control. A locking mechanism is used to fix the linear slide rail 3 to the rotatable bracket 4, and the launch angle can be adjusted to prevent deviation during launch, ensuring that the angle positioning deviation is less than 1 degree. The linear slide rail 3 realizes stepless adjustment of the launch angle of the friction wheel 2 from 0° to 90° through transmission, which can meet the requirements of various launch angles and improve the flexibility and applicability of the system. After the launch angle is preset and adjusted in this embodiment, it is fixed, and the angle positioning deviation of the rotatable bracket 4 < 1°.

[0031] As Figure 1 and Figure 2As shown, a material guiding groove 8 is provided at the discharge end of the particle placement groove 5. The material guiding groove 8 is used to accurately align the adjustable guiding pipe with the biting area of the two friction wheels 2, and the particles slide down by their own weight to ensure that the particles enter the launching area. The design of the material guiding groove 8 ensures that the particles can smoothly slide into the biting area of the two friction wheels. The design of the bottom inclination angle utilizes the self-weight of the particles to ensure that the particles can smoothly enter the launching area and improve the launching efficiency.

[0032] In the waterproof design, a fully enclosed waterproof structure is equipped with a multiple sealing protection system. The multiple sealing protection system adopts the design of a fully enclosed waterproof structure, and each functional module is equipped with a multiple sealing protection system to ensure that moisture can be effectively prevented from invading during underwater operations and the internal components are protected from damage. A customized waterproof motor is selected, and its output shaft adopts a composite sealing structure to effectively block the intrusion of water. The rail adjustment mechanism and the angle rotation device continuously move in water and adopt a multi-layer sealing design.

[0033] The fully enclosed waterproof structure ensures the normal operation of the entire device in the underwater environment. The customized waterproof motor and the composite sealing structure ensure that the core power unit can still effectively block the intrusion of water under the condition of high-speed rotation. The multi-layer sealing design of the moving parts ensures long-term stable operation in the underwater environment. The potting process of the control unit and the cable interface of the launching device further improves the waterproof performance of the system and ensures the stable execution of the particle launching task in complex underwater conditions. The composite sealing structure includes but is not limited to multiple sealing measures such as rubber sealing rings and labyrinth seals to ensure the reliability of the motor in harsh environments.

[0034] In the modular design, the dual-driving system adopts 2 waterproof motors and their control units. The multi-dimensional adjustment mechanism includes a rail adjustment mechanism and an angle rotation device. The control unit is used for real-time monitoring and intelligent control to ensure that the system can quickly respond in case of abnormalities. The control unit and the cable interface are fully sealed and protected through the potting process. The potting process can completely wrap the control unit and its connection parts in the sealing material to prevent moisture penetration. The entire system has been verified by continuous operation in a simulated deep-sea environment, proving that it can stably execute the particle launching task in complex underwater conditions and ensure the long-term reliable operation of the system.

[0035] The launching device adopts the design of a fully enclosed waterproof structure, and each functional module has a waterproof effect; the core power unit selects a customized waterproof motor, and its output shaft adopts a composite sealing structure, which can still effectively block the intrusion of water under the condition of high-speed rotation; the moving parts include a rail adjustment mechanism and an angle rotation device, which can continuously move in water; the control unit and the cable interface are fully sealed and protected through the potting process; the entire system has been verified by continuous operation in a simulated deep-sea environment and can stably execute the particle launching task in complex underwater conditions.

[0036] The overall launch device adopts a modular design, integrating a dual-drive system, a multi-dimensional adjustment mechanism, and a control unit. It is waterproofed to meet the requirements of underwater experiments. The launch efficiency is ≥30 grains / minute, and the effective range can reach 6m. It is applicable to the study of the collision characteristics between particles and the riser during deep-sea mining.

[0037] The modular design enables each part of the system to be independently replaced and adjusted, facilitating installation and maintenance. Users can quickly replace or adjust different modules according to specific experimental requirements to achieve personalized configuration of the system. The control unit ensures that the system responds promptly in case of anomalies through real-time monitoring and intelligent control, reducing the occurrence of accidents.

[0039] Install the high-speed dual-drive module, multi-dimensional adjustment mechanism, and control unit on the experimental platform. Ensure that the multi-layer sealing structure of all components is intact to prevent moisture intrusion.

[0040] Set the speeds of the two waterproof motors through an independent speed regulator to achieve the required initial particle velocity.
