Description

Technical Field

[0001] The present invention belongs to the technical field of deep - sea mining equipment, and particularly relates to a deep - sea mining particle collision and emission device and a control method based on the principle of motor friction drive. Background Art

[0002] In the field of deep - sea mining technology, the research on the collision characteristics between seabed mineral particles and the lifting pipeline is the key foundation for ensuring the efficient transportation of minerals and the safe operation of equipment. Due to the complexity and particularity of the deep - sea environment, the motion behavior of particles under the action of high pressure and multiphase flow media is significantly different from that in terrestrial or shallow - sea scenarios. However, the current experimental research methods for this problem are severely lagging behind. Most rely on theoretical models or simplified devices for deduction, making it difficult to truly reproduce the dynamic interaction process between particles and the pipe wall under extreme deep - sea working conditions, resulting in a lack of reliable basis for obtaining key collision parameters.

[0003] Existing experimental technologies face multiple bottlenecks: First, the environmental simulation ability of conventional equipment is limited, and it cannot effectively reproduce the influence of deep - sea high pressure and complex fluid conditions on the particle motion trajectory, resulting in a large deviation between experimental results and actual working conditions; Second, the stability and controllability of particle emission devices are insufficient, making it difficult to accurately control the initial velocity, attitude, and particle size distribution of particles, resulting in poor experimental repeatability and low data credibility; In addition, traditional monitoring means are limited by hardware performance and are difficult to capture the mechanical response and energy transfer characteristics during the transient collision process, restricting the in - depth analysis of collision mechanisms. Although some patents and literatures have attempted to improve experimental accuracy by modifying the emission mechanism or integrating multiple sensors, these solutions generally have problems such as weak environmental adaptability and limited control ability, and cannot meet the requirements of deep - sea mining engineering for high - fidelity experimental data.

[0004] Therefore, it has become an urgent need to develop a set of particle emission and collision analysis systems dedicated to deep - sea mining scenarios. This system needs to solve the above - mentioned deficiencies of existing technologies, realize the adjustable control of particle motion parameters, thereby providing a reliable experimental platform for revealing the particle - pipe wall collision law and optimizing the pipeline structure design, and promoting the development of deep - sea mining technology towards high - efficiency and intelligent directions. Summary of the Invention

[0005] The present invention provides a deep - sea mining particle collision and emission device and a control method. This device can effectively solve the problem that existing technologies cannot study the particle motion trajectory and collision mechanical characteristics in the context of deep - sea mining, and provide a new experimental scheme for the subsequent optimization design of deep - sea mining pipeline structures and the research and development of high - reliability equipment.

[0006] To solve the above problems, the technical solutions provided by the present invention are as follows:

The 220V power supply (8) is electrically connected to the motors (1) through the speed regulators (7). The output shaft of the motor (1) is connected to the friction wheel (2). The working surfaces of the two friction wheels (2) are arranged in a coplanar and parallel manner, and through the speed regulators (7), they perform rotational movements in opposite directions with synchronized speeds, forming a two - way clamping and accelerating structure for the particles; the slide rail distance - adjusting mechanism (4) is connected to the two motors (1) and steplessly adjusts the distance between the two friction wheels (2) according to the size of the particles to be emitted; the feeding system is located directly below the contact area of the two friction wheels (2). The feeding system includes a particle storage cavity (6), a feeding channel (5), and a servo motor (3).

The servo motor (3) controls the opening and closing of the feeding channel (5) to achieve directional particle feeding, and the particle storage cavity (6) is docked with the contact area of the two friction wheels (2).

[0008] In a preferred embodiment of the present invention, the particle storage cavity (6) is a circular metal structure. The circular metal structure is provided with a slide rail facing the contact area of the two friction wheels (2), and the slide rail is docked with the contact area of the two friction wheels (2).

[0009] In a preferred embodiment of the present invention, the feeding channel (5) is a long - strip structure, and the long - strip structure is provided with a guide rail.

[0010] In a preferred embodiment of the present invention, the surface of the friction wheel (2) is coated with a functional coating. The functional coating is a rubber - based nanocomposite with high elasticity and wear resistance, or a metal functional layer treated by sandblasting, which is used to effectively increase the friction coefficient with the particle surface, without causing damage to the particle surface while ensuring the clamping force, and helps to improve the stability of the particle acceleration process.

[0011] In a preferred embodiment of the present invention, the slide rail distance - adjusting mechanism (4) includes a precision slide rail assembly and a drive adjustment system. The precision slide rail assembly is rigidly connected to the drive units at both ends through a linear guiding mechanism. The drive adjustment system is composed of a rotary power source, a screw drive mechanism, a displacement locking device, and an electromagnetic braking component, which can continuously adjust the distance between the two friction wheels (2) according to the external dimensions of the target particles. Among them, the electromagnetic braking component can achieve gap - free fixation at any adjusted position.

[0013] Step 1: The dual-wheel reverse drive module consists of two independent drive units arranged symmetrically. Each unit includes a motor (1) and a friction wheel (2) coaxially assembled with its output shaft. The working surfaces of the two friction wheels (2) are arranged coplanarly and parallel, and through a speed governor (7), they achieve reverse rotational motion with synchronized speeds, forming a bidirectional clamping and accelerating structure for the particles.

[0023] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a particle collision emission device for deep-sea mining, including a double-wheel reverse drive module, a slide rail distance adjustment mechanism 4, and a feeding system. The double-wheel reverse drive module includes a 220V power supply 8, two speed regulators 7, two motors 1, and two friction wheels 2. The 220V power supply 8 is electrically connected to the motor 1 through the speed regulator 7. The output shaft of the motor 1 is connected to the friction wheel 2. The working surfaces of the two friction wheels 2 are arranged in a coplanar and parallel manner, and rotate in opposite directions with synchronous speeds through the speed regulator 7 to form a two-way clamping and accelerating structure for the particles. The slide rail distance adjustment mechanism 4 is connected to the two motors 1 and steplessly adjusts the distance between the two friction wheels 2 according to the size of the particles to be emitted. The feeding system is located directly below the contact area of the two friction wheels 2. The feeding system includes a particle storage cavity 6, a feeding channel 5, and a servo motor 3. The particle storage cavity 6 and the servo motor 3 are respectively connected to the two ends of the feeding channel 5. The servo motor 3 controls the opening and closing of the feeding channel 5 to achieve directional particle feeding, and the particle storage cavity 6 is docked with the contact area of the two friction wheels 2.

[0024] The particle storage cavity 6 is a circular metal structure. The circular metal structure is provided with a slide rail facing the contact areas of the two friction wheels 2, and the slide rail is in contact with the contact areas of the two friction wheels 2. The feeding channel 5 is a strip-shaped structure, and the strip-shaped structure is provided with a guide rail.

[0025] The slide rail distance adjustment mechanism 4 of this embodiment includes a precision slide rail assembly and a drive adjustment system. The precision slide rail assembly is rigidly connected to the drive units at both ends through a linear guiding mechanism, and the drive unit is preferably a servo motor. The drive adjustment system consists of a rotary power source, a screw transmission mechanism, a displacement locking device, and an electromagnetic braking assembly, and can continuously adjust the distance between the two friction wheels 2 according to the external dimensions of the target particles. Among them, the electromagnetic braking assembly can achieve gapless fixation at any adjusted position. The displacement locking device can keep the distance between the friction wheels stable after the adjustment is completed.

[0026] Each functional subsystem of a particle collision emission device for deep-sea mining is integrated through electrical and mechanical interfaces, and cooperates to achieve high-precision, adjustable-speed, and directional emission operations of particles with different sizes and different forms. The double-wheel reverse drive module includes two motors and friction wheels coaxially installed with them. The two friction wheels are arranged symmetrically, driven by their respective motors, and set to rotate in reverse, ensuring that the particles are subjected to symmetric and balanced clamping and acceleration effects after entering the emission area. This arrangement not only ensures the stable emission of particles along the predetermined direction, but also significantly improves the stability of attitude maintenance and reduces the risk of deviation during the movement process.

[0027] Furthermore, to enhance the force coupling relationship between the particles and the friction wheels, improve the acceleration efficiency and reduce the probability of particle slipping. The surface of the friction wheel 2 in this embodiment is coated with a functional coating, and the functional coating is a rubber-based nanocomposite with high elasticity and wear resistance, or a metal functional layer treated by sandblasting, which is used to effectively increase the friction coefficient with the particle surface, and does not cause damage to the particle surface while ensuring the clamping force, which helps to improve the stability of the particle acceleration process. Further, to meet the high-precision emission requirements of particles with different diameters, the slide rail distance adjustment mechanism 4 is arranged above the friction wheel base, and its function is to steplessly adjust the distance between the two friction wheels and accurately adjust the width of the clamping channel.

[0028] The embodiment of the present invention provides a particle collision emission control method for deep-sea mining, including:

[0029] Step 1, the double-wheel reverse drive module consists of two independent drive units arranged symmetrically. Each unit includes a motor 1 and a friction wheel 2 coaxially assembled with its output shaft; the working surfaces of the two friction wheels 2 are arranged coplanarly and parallelly, and through a speed regulator 7, a reverse rotational movement with synchronous speed is realized, forming a two-way clamping and acceleration structure for the particles;

[0030] Step 2: The slide rail distance adjustment mechanism 4 is connected to the two motors 1, and the distance between the two motors 1 is steplessly adjusted according to the size of the particles to be launched, so as to adjust the distance between the two friction wheels 2.

[0031] Step 3: The feeding system is driven and controlled by the servo motor 3 to achieve feeding. The servo motor 3 precisely controls the opening and closing of the feeding channel 5 to realize the single-particle orderly release of the particles, thus avoiding the problems of jamming or uneven acceleration caused by multiple particles entering the contact area between the two friction wheels 2 at the same time.

[0032] Step 4: The two friction wheels 2 are respectively driven by the two motors 1 and rotate in opposite directions to form a pair of friction wheel pairs rotating in reverse. When the particles are sent into the contact area between the two friction wheels by the feeding system, the surface of the friction wheel contacts the particles and applies tangential forces in opposite directions, so as to clamp and accelerate the particles, and finally launch the particles at a high speed along the set direction.

[0033] Step 5: According to the physical property parameters of the target particles, first set the preset wheel distance of the two friction wheels through the slide rail distance adjustment mechanism 4. The feeding system conveys the particles to the contact area of the two friction wheels at a set frequency. The friction wheel pair rotating in reverse forms an instantaneous collision acceleration for the particles, so as to realize the launch of particles of different sizes.

[0034] Step 2 specifically includes: The slide rail distance adjustment mechanism 4 includes a precision slide rail assembly and a drive adjustment system. The slide rail assembly is rigidly connected to the two end drive units through a linear guiding mechanism. The drive adjustment system is composed of a rotary power source, a screw transmission mechanism, a displacement locking device and an electromagnetic braking assembly, and can continuously adjust the distance between the two friction wheels 2 according to the external dimension of the target particles. Among them, the electromagnetic braking assembly can achieve gapless fixation at any adjustment position.

[0035] Step 5 specifically includes: According to the size of the particles to be launched, adjust the distance between the friction wheels through the slide rail distance adjustment mechanism; control the feeding system by the servo motor to place the particles between the two friction wheels in turn and orderly; start the two high-speed motors to make the friction wheels rotate at high speed in opposite directions to form a reverse acceleration channel; the particles obtain the required initial velocity when passing through the friction wheels to realize directional launch, which is used to study the collision behavior with the pipe wall surface.

[0036] Example 1:

[0037] To more clearly illustrate the working principle and implementation effect of the present invention, the following is combined with the actual structure and operation process. The particle collision emission device in Example 1 is applied to a deep-sea mining experimental system. Particles with a diameter of 10 mm are selected to carry out directional emission tests. After the implementation starts, a single particle is precisely released through the control of a servo motor. After the particle enters between the friction wheels, it is quickly accelerated under the high friction force of the functional coating and finally emits from the device with an initial velocity of about 5 m / s, completing a stable directional emission. The key parameters of the particle collision movement are extracted through experiments, indicating that the emission device of the present invention can achieve high-precision attitude maintenance and direction control.

It is not necessary and impossible to enumerate all the implementation manners here.
