Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water surface cleaning, in particular to a front-end pretreatment device for sucking and cleaning of clustered marine organisms and floating objects. BACKGROUND

[0002] Every summer, a large number of disaster-causing materials such as Enteromorpha, Chlorella, Potamogeton, and Laminariae are generated in some nuclear power plants. The nuclear power plants generally use a suction device combined with a pipeline to clean them. A horn-shaped design is used at the front end of the pipeline to connect with the tail pocket of the intercepting net, which can increase the suction range and improve the cleaning efficiency.

[0003] Although the horn-shaped design can increase the suction range by enlarging the inlet diameter, it becomes a shortcoming during the outbreak of disaster-causing materials. The large inlet causes a large number of clusters to be sucked in at the same time, which exceeds the instantaneous processing capacity of the pipeline. The tail pocket of the intercepting net accumulates clustered and dense disaster-causing materials. The clustered disaster-causing materials enter the pipeline, reducing the flowability of the medium in the pipeline, and causing the pipeline and the suction device to be blocked, thereby increasing the workload of the workers for maintenance.

DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0022] Embodiment one, refer to Figures 1-5 A leading pretreatment device for sucking and cleaning of clustered marine organisms and floating objects, comprising a buoyancy platform 1, a docking structure 6, a controller, and a dispersion assembly 9, the middle part of the buoyancy platform 1 is provided with a processing cabin 7, the buoyancy platform 1 and the processing cabin 7 provide a stable offshore operation base and form a centralized material processing space, the processing cabin 7 serves as the core channel of the entire cleaning operation, the buoyancy platform 1 is fixedly installed with a guardrail assembly 2 and a waterproof cabin 3, the waterproof cabin 3 is provided with a cutting device 4, the buoyancy platform 1 is composed of a steel framework and a buoy, ensuring the buoyancy and structural strength of the platform, the front end of the processing cabin 7 is provided with a chute 71, the docking structure 6 is installed on the buoyancy platform 1 through cooperation with the chute 71, the tail end of the processing cabin 7 is provided with a connecting flange 72 and is connected with a suction pipe, and the dispersion assembly 9 is composed of a turbulence triggering assembly and a liquid spraying assembly. The turbulence triggering assembly is arranged in the processing cabin 7 and corresponds to the center of the inlet of the processing cabin 7. The liquid spraying assembly is arranged inside the turbulence triggering assembly.

[0023] In this embodiment, the device adopts a modular design, which is convenient for manufacturing, transportation, and on-site assembly; the processing cabin 7 regularizes the chaotic suction flow field, providing a stable and controllable working environment for the dispersion assembly 9 and the cutting device 4 installed inside.

[0024] Further, the dispersion assembly 9 is located at the front side of the inner cavity of the treatment cabin 7, and the cutting device 4 is located at the rear side of the inner cavity of the treatment cabin 7. The dispersion assembly 9 serves as a primary treatment unit and is placed at the most front end of the material flow (the front side of the treatment cabin 7). When the compacted disaster-causing materials (mainly compacted marine organisms and floating objects) are sucked into the treatment cabin 7, they first encounter the combined action of rotation, vibration and impact, which can break down the large, entangled clumps into smaller, loose individuals. Subsequently, these pre-processed materials continue to flow backward with the water flow to the cutting device 4 located at the rear side of the treatment cabin 7. At this time, the cutting device 4 is not faced with stubborn large clumps that are difficult to cut directly, but with materials that have been loosened and greatly reduced in size. This avoids direct contact between the cutting device 4 and the large clumps of difficult-to-handle materials, significantly improving the processing efficiency and smoothness of the entire system. The front-mounted dispersion assembly 9 effectively protects the relatively precise cutting device 4, reducing the risk of overload, jamming or wear, thereby prolonging the service life of the entire equipment. This hierarchical processing mode fundamentally avoids the instantaneous blockage caused by insufficient single-stage processing capacity, ensuring the sustained stability of the medium flow in the suction pipeline.

[0025] The cutting device 4 is provided with two groups in parallel. After setting the spacing, the cutting device 4 can effectively cut the disaster-causing materials. The cutting device 4 is composed of two sawtooth blades that are attached together. The cutting function is achieved through the reciprocating motion of the blades. The reciprocating motion (similar to the motion of scissors or electric hair clippers) has a unique advantage in cutting long fibers and tough materials. Its shearing action is more labor-saving and efficient than the rotating cutting action, especially good at handling materials such as seaweed and ropes that are prone to winding around the rotating shaft. It can effectively prevent the material from winding around the shaft, maintaining the ability of the device to work continuously. The sawtooth blades of the cutting device 4 extend into the treatment cabin 7.

[0026] It should be noted that the buoyant platform 1 corresponding to the dispersion assembly 9 is provided with a treatment window. The buoyant platform 1 corresponding to the treatment window is hingedly installed with a cover plate 5. The dispersion assembly 9, as a front-line component that directly contacts with the debris, is an area that needs to be observed and maintained. By opening the cover plate 5, the working staff can directly observe the working state of the dispersion assembly 9 and the pre-processing effect of the material. In the case of abnormal blockage (such as the suction of large foreign objects), the cover plate 5 can be quickly opened for manual cleaning without the need to lift the entire device out of the water, achieving non-stop or rapid recovery. This facilitates the daily inspection and maintenance of the components in this area, ensuring the continuous and efficient performance of the cleaning operation. The front side of the docking structure 6 is sleeved and clamped with an interception net bag 61. The interception net bag 61 can preliminarily gather and intercept the disaster-causing materials before they enter the treatment cabin 7, preventing them from drifting away from both sides of the platform and ensuring the suction efficiency. The top of the docking structure 6 is provided with a lifting handle part, which provides a clear force point for the working staff, making the operation of lifting, aligning and plugging the docking structure 6 labor-saving, accurate and safe.

[0027] In the embodiment, the application mainly consists of a buoyant platform 1, a guardrail assembly 2, a waterproof cabin 3, a cutting device 4, a cover plate 5, a treatment cabin 7, a dispersion assembly 9 and a docking structure 6. The buoyant platform 1 is composed of a steel framework and a buoy, which can ensure the safety of the docking of the staff device and the interception net bag 61. The modular design is adopted, the treatment cabin 7 is arranged in the middle, the dispersion assembly 9 and the cutting device 4 are carried to cut and separate the disaster-causing objects in the treatment cabin 7, the sliding groove 71 is arranged at the front end of the treatment cabin 7 for the installation of the docking structure 6, the connecting flange 72 is arranged at the tail end for the docking of the suction pipeline, and the buoyant platform 1 serves as a carrier for the installation of the guardrail assembly 2, the waterproof cabin 3, the cutting device 4, the cover plate 5, the treatment cabin 7 and the docking structure 6.

[0028] The guardrail assembly 2 is composed of iron chains and guardrails, which protects the safety of the staff in the sea operation, and the guardrail assembly 2 is installed on the buoyant platform 1. The waterproof cabin 3 protects the cutting device 4 from being wetted by rain, so that the cutting device 4 can work normally in rainy days, and also plays a protective role to prevent the staff from being cut by touching the cutting device 4. The waterproof cabin 3 is installed on the buoyant platform 1. The cutting device 4 is installed and fixed on the buoyant platform 1, and relies on the waterproof cabin 3 to play a rainproof role. The cover plate 5 is installed on the buoyant platform 1 and can be opened to observe whether the water grass is cut. The docking structure 6 is installed in the front end sliding groove 71 of the buoyant platform 1 in a plug-in manner, which is stable and firm in installation, as shown in Figures 2-3 .

[0029] A field implementation step of a leading pretreatment device for suction cleaning of clustered marine organisms and floating objects: The buoyant platform 1 adopts a modular design, and the guardrail assembly 2, the waterproof cabin 3, the cutting device 4, the cover plate 5, the treatment cabin 7, the dispersion assembly 9 and the docking structure 6 can be installed. After being installed with the suction pipeline, the buoyant platform 1 is hoisted into the water, the staff walks onto the buoyant platform 1 from the guardrail assembly 2, lifts the docking structure 6 from the sliding groove 71 at the front end, lifts the interception net bag 61 and puts it into the docking structure 6, tightens the cable after putting it in, and then disassembles it into the front end sliding groove 71 of the buoyant platform 1, as shown in Figure 4 . The suction device (provided in the application, prior art, not described again) is started, the suction force drives the water flow in the middle treatment cabin 7 of the buoyant platform 1 to flow faster, the disaster-causing objects are sucked from the interception net bag 61, treated by the dispersion assembly 9 first, and then cut by the cutting device 4. After the cutting device 4 is started, the disaster-causing objects are cut and separated and sucked into the pipeline, and then transported to the collection site.

[0030] Example two, refer to Figures 5-12The turbulence triggering assembly comprises two fixed discs 8, a speed reducer 91 and a cylinder 92. The two fixed discs 8 are symmetrically arranged on the inner wall of the processing cabin 7, and the two fixed discs 8 are connected through a connecting pipe 81. The cylinder 92 is sealingly sleeved on the two fixed discs 8 and is rotationally connected with the two fixed discs 8. A plurality of conical columns 93 are equidistantly arranged on the cylinder 92. The speed reducer 91 is fixedly arranged on the outside of the processing cabin 7. The output end of the speed reducer 91 penetrates through the side wall of the processing cabin 7 and the fixed disc 8 and extends to the inside of the cylinder 92. A gear 911 is fixedly connected to the output end of the speed reducer 91 located inside the cylinder 92. A gear ring 912 meshing with the gear 911 is fixedly connected to the inner wall of the cylinder 92 corresponding to the gear 911. A plurality of mounting discs 97 are fixedly connected to the inner wall of the cylinder 92. A plurality of mounting rods 971 are fixedly connected between the mounting discs 97. The output shaft of the speed reducer 91 extends into the inside of the cylinder 92 to drive the gear 911 to rotate. The power is transmitted to the entire cylinder 92 through the meshing with the gear ring 912 fixedly connected to the inner wall of the cylinder 92, so that the cylinder 92 slowly rotates around the axis of the fixed connecting pipe 81. The power source is arranged outside the cabin, which is convenient for maintenance and ensures the integrity of the structure in the cabin. When the cylinder 92 rotates, the conical columns 93 continuously impact, pull and comb the clustered disaster-causing objects sucked into the processing cabin 7.

[0031] It should be noted that the disaster-causing objects entering the processing cabin 7 are separated by the cylinder 92 and the conical columns 93, so that the disaster-causing objects can be dispersed to the upper and lower areas of the processing cabin 7. Under the action of the suction force at the connecting flange 72 in the middle part, the disaster-causing objects can be dispersed to different parts of the cutting knife, improving the cutting effect of the clustered disaster-causing objects and avoiding the blockage of the suction pipeline.

[0032] It should be noted that the rotation of the cylinder 92 and the arrangement of the conical columns 93, combined with the suction force and the vibration force of the cylinder 92, can easily cause the long strip of seaweed and other disaster-causing objects to fall off.

[0033] Further, the mounting disc 97 is sealingly and rotationally connected between the connecting pipe 81, which can prevent liquid leakage. The inner cavity of the cylinder 92 is divided into a plurality of chambers by the mounting disc 97. A supporting arm 94 is fixedly connected to the outer side wall of the connecting pipe 81 corresponding to each chamber. A limiting sleeve 98 is rotationally connected to the mounting rod 971 corresponding to the supporting arm 94. Eccentric blocks 981 are fixedly connected to the two sides of the limiting sleeve 98. The supporting arm 94 is arranged towards the inlet direction of the processing cabin 7, so that the action direction of the sharp conical part 962 is opposite to the flow direction of the disaster-causing objects. On the basis of the original conical column 93, the dispersion effect is further improved.

[0034] With the rotation of the barrel 92, the mounting rod 971 mounted on the inner wall mounting disc 97 of the barrel 92 will drive the limiting sleeve 98 on it to sweep the stationary support arm 94 in turn. Since the limiting sleeve 98 has eccentric blocks 981 fixed on both sides, when the support arm 94 scratches the outer anti-skid pattern of the limiting sleeve 98, it will exert a transient impact force on it. This impact force will force the limiting sleeve 98 with the eccentric blocks 981 to rotate. During the rotation of the eccentric blocks 981, the long arm end of the eccentric blocks 981 will exert a transient impact force on the inner wall of the barrel 92. The vibration caused by this impact is transmitted to the entire barrel 92 through the mounting rod 971 and the mounting disc 97, finally making the barrel 92 and all the conical columns 93 in a high-frequency, small-amplitude vibration state. This high-frequency vibration makes it difficult for the fiber to adhere stably on the surface of the conical column 93, and the suction force of the auxiliary suction pipe is also increased, achieving the active self-cleaning effect of timely vibration and ensuring that the equipment always maintains high efficiency in long-term operation. The vibration itself also helps to shake off the internal bonding force of the material clumps, complementing the rotational impact and improving the pretreatment effect.

[0035] It should be noted that the conical column 93 has a receiving cavity 931 inside, and a magnetic block 96 is slidably connected in the receiving cavity 931. The side of the magnetic block 96 away from the connecting pipe 81 is fixedly connected with a connecting rod 961, the end of the connecting rod 961 penetrates through the end of the conical column 93 and is fixedly connected with a pointed cone part 962 thereon. The magnetic block 96 and the receiving cavity 931 are elastically connected by a spring 963. The end of the support arm 94 is provided with a magnetic force area 941, and the magnetic force area 941 has the same magnetism as the opposite side of the magnetic block 96. Inside each conical column 93, there is a vibration system composed of a magnetic block 96 and a spring 963. The magnetic block 96 and the magnetic force area 941 at the end of the support arm 94 are opposite poles, generating a repulsive force.

[0036] Further, the outer side of the speed reducer 91 is provided with a waterproof cover, the end of the support arm 94 is arc-shaped, and the outer side wall of the limiting sleeve 98 is provided with an anti-skid pattern, ensuring that the contact between the support arm 94 and the limiting sleeve 98 is smooth and non-rigid collision, effectively transmitting the excitation force and reducing impact noise and wear. When the barrel 92 rotates, the support arm 94 can intermittently contact different limiting sleeves 98. The distance between the central axis of the mounting rod 971 and the long arm end of the eccentric block 981 is equal to the distance between the central axis of the mounting rod 971 and the inner wall of the barrel 92, ensuring that the excitation force generated by the eccentric block 981 when vibrating can be most effectively transmitted to the inner wall of the barrel 92, maximizing the vibration effect.

[0037] In this embodiment, when the speed reducer 91 starts, the driving cylinder 92 rotates stably around the fixed connecting pipe 81 axis through the meshing transmission of the gear 911 and the gear ring 912, the conical columns 93 equidistantly distributed on the outer wall of the cylinder 92 rotate with it, forming a dynamic mechanical barrier, the rotating cylinder 92 and conical columns 93 physically divide and guide the concentrated disaster material flow, and forcibly make it dispersed to the upper and lower space of the processing cabin 7. This structure changes the traditional pipeline material concentrated in the middle of the flow field distribution, so that the subsequent cutting device 4 can make full use of its entire working area, avoids local overload, and significantly improves the overall cutting efficiency and uniformity.

[0038] The continuous rotation of the conical columns 93 mechanically impacts and combs the material lumps, achieving preliminary crushing, and the conical design makes it easier for the winding material to slip off under the action of rotating centrifugal force and subsequent vibration, laying the foundation for anti-winding.

[0039] Inside the cylinder 92, the supporting arm 94 fixed on the connecting pipe 81 acts as a static trigger point. When the cylinder 92 rotates, the limiting sleeve 98 on the mounting rod 971 sweeps across the supporting arm 94 in turn. The eccentric blocks 981 on both sides of the limiting sleeve 98 make its mass distribution uneven. The scraping of the supporting arm 94 generates a momentary torque on the eccentric blocks 981 through the limiting sleeve 98, forcing them to rotate and vibrate in inertia, and making them contact with the inner wall of the cylinder 92 to produce high-frequency micro-amplitude vibration. It makes it difficult for materials, especially long strip seaweed, to form stable adhesion with the equipment surface, combined with suction force, realizes the initiative self-cleaning effect of "winding and vibration falling", ensures that the equipment is free from blockage in long-term continuous operation, and the vibration wave is transmitted to the inside of the material lump, which can effectively destroy the bonding force between the fibers, play a role in loosening, and form mechanical complementation with rotation impact, greatly reducing the energy consumption and load of subsequent cutting.

[0040] Inside each conical column 93, there is an impact system composed of a magnetic block 96 and a spring 963. When the conical column 93 rotates to the point where the magnetic block 96 inside it and the magnetic force area 941 at the end of the supporting arm 94 are same-pole and coincide, the strong magnetic repulsion instantly pushes the magnetic block 96 and the sharp cone part 962 connected with it to stretch out. When the magnetic block 96 is out of the magnetic force area 941, the magnetic force weakens and the restoring force of the spring 963 acts together to make the sharp cone part 962 retract rapidly. This process is repeated every time the cylinder 92 rotates one revolution, making each sharp cone part 962 produce high-frequency, small-stroke reciprocating impact motion. The shock force generated when the sharp cone part 962 returns to its original position and the shock force generated by the eccentric block 981 act on the dispersion assembly 9. This composite vibration ensures that the dispersion assembly 9 at the front end of the processing cabin 7 always maintains extremely high smoothness. The disaster material is rapidly dispersed and transported backward at this point, almost eliminating the possibility of structural blockage in the preprocessing stage, providing a fundamental guarantee for the stable operation of the rear-end cutting device 4 and the entire suction system.

[0041] The arm 94 and the magnetic force area 941 thereon are arranged towards the entrance direction of the treatment cabin 7, and the purpose is to ensure the high-frequency micro-impact movement of the sharp cone part 962 excited thereby, and the action direction is opposite to the main flow direction of the disaster-causing object. When the disaster-causing object flows forward under the action of the suction force, the sharp cone part 962 is high-frequency punctured against the flow direction, and the impact speed of the sharp cone part 962 is superimposed with the flow speed of the disaster-causing object in the vector, so that the instantaneous force of the micro-impact is significantly amplified, and the breaking strength far exceeds that in the static state or in the same direction, and the structure of the disaster-causing object mass can be more easily cut in and torn. The strong instantaneous impact force can effectively overcome the overall inertia of the material, and start to resist and disintegrate it from the front end, destroy the integrity of the mass, and create extremely favorable conditions for subsequent vibration loosening and rotary crushing, and the dispersion effect is much better than that of only relying on the rotary scraping of the conical column 93. This design skillfully converts the flow resistance that must be overcome into a breaking driving force, and the kinetic energy of the disaster-causing object flow is not wasted, but is used to enhance the destruction effect of the micro-impact, realizes efficient use of fluid energy, and makes the pretreatment process more energy-saving and intense.

[0042] Embodiment three, with reference to Figures 12-14 The liquid injection assembly includes a plurality of impellers 83 and volutes 95, wherein the impellers 83 are fixedly connected to the outer side wall of the connecting pipe 81, the volutes 95 are fixed to the side wall of the mounting disc 97, and the side of the volute 95 away from the corresponding mounting disc 97 is connected with a liquid guide ring 951 in a penetrating manner. The side wall of the connecting pipe 81 corresponding to the liquid guide ring 951 is provided with a liquid guide hole 82 downward, so that the liquid in the connecting pipe 81 can smoothly enter the liquid guide ring 951 through the liquid guide hole 82. The volute 95 is eccentrically arranged between the volute 95 and the impeller 83, and the volute 95 is rotatably sleeved outside the corresponding impeller 83. The outlet of the volute 95 penetrates the side wall of the cylinder 92, and the two ends of the connecting pipe 81 are fixedly provided with sealing plugs 84. One of the sealing plugs 84 is connected with the liquid supply system of the buoyant platform 1 through a pipeline, and the liquid supply system is used for conveying working liquid into the connecting pipe 81. The working liquid can be seawater.

[0043] It should be noted that there is a gap between the inner cavity of the liquid guide ring 951 and the blades of the impeller 83, which not only ensures that the liquid can smoothly enter the pumping cavity, but also avoids contact and wear between rotating and fixed parts, and runs stably and reliably. The liquid guide ring 951 and the connecting pipe 81 are sealingly and rotatably connected, the inside of the outlet of the volute 95 is provided with a drainage groove 952 for the last flow guiding and flow straightening of high-speed fluid, so as to ensure smooth flow and reduce vortex loss, and further optimize the pumping efficiency. The outlet end of the volute 95 is provided with a spray port 953, which is unidirectionally arranged. It can prevent the sewage and sundries in the treatment cabin 7 from flowing backward when the machine is stopped or the pressure is insufficient, effectively protect the internal flow channel, and ensure the immediate response when the system starts and the internal cleaning during long-term operation.

[0044] In this embodiment, when the cylinder 92 rotates, the volute 95 rotates at high speed. The working fluid located in the gap between the impeller 83 and the volute 95 is subjected to the combined action of strong viscous shear force and centrifugal force from the inner wall of the rotating volute 95. The blades of the fixed impeller 83 efficiently convert this chaotic tangential flow into axial flow pointing towards the outlet of the volute 95. The kinetic energy of the liquid is converted into pressure energy in this process, and finally a high-pressure jet is ejected from the nozzle 953. As the outlet of the volute 95 rotates with the cylinder 92, the pumped liquid is thrown out by centrifugal force, instantly forming a dynamic annular liquid curtain covering the entire inlet cross-section of the treatment chamber 7.

[0045] The clumps of hazardous materials being drawn into the treatment chamber 7 must first pass through this high-speed rotating annular liquid curtain. Utilizing the kinetic energy of the water jet, the dense clumps of hazardous materials are directly impacted and loosened. Simultaneously, a water film is formed on the surface of the materials and equipment, effectively reducing friction and entanglement. In addition, the rotational shear force of the liquid curtain and the forward movement of the hazardous materials create intense turbulence. The shear force of the water flow assists in conveying the broken materials backward, preventing local accumulation. This significantly reduces the entanglement and overall strength of the hazardous materials, making it easier for them to be broken up by the subsequent conical column 93 and cut by the cutting device 4. This means that the working resistance of the mechanical components is greatly reduced, the driving energy consumption of the entire system is reduced, and the wear of the equipment is also slowed down, extending the service life of key mechanical components.

[0046] In Example 4, preferably, a flexible thin-film pressure sensor can be embedded in the inner key node of the interception net 61 and electrically connected to the controller. When the system is running unloaded, the initial value of the sensor (mainly the weight of the tail bag and the impact force of the water flow) is recorded, and the sensor value is continuously monitored. When the hazard accumulates in the tail bag, the weight of the tail bag and the force-bearing area increase, causing the sensor reading to rise continuously. When the sensor value exceeds the preset first-level threshold, the control system automatically starts the dispersion component 9 and the spray component to begin pretreatment. If the blockage continues to worsen and the value exceeds the second-level threshold, the power of the dispersion component 9 and the spray component is increased to the highest level. When the pressure sensor value falls back to near the initial baseline, it is determined that the cleaning is complete, and the components are automatically shut down after a delay. Through the above settings, the equipment is prevented from running unloaded when there is no hazard, saving energy, and at the same time, it can prevent equipment overload damage caused by forced start-up under extreme blockage.

[0047] Furthermore, a current sensor is installed on the drive motor of the cutting device 4 and electrically connected to the controller. A flow meter is installed near the connecting flange 72 of the suction pipe. The greater the motor load, the higher the current. Under good conditions, the motor current of the cutting device 4 is stable within a medium range and accompanied by regular small fluctuations (indicating continuous and stable material cutting). The flow rate in the pipe is stable at a high level, which indicates that the pre-dispersion and current-stage cutting effects are good, the material size is appropriate, and the pipe is unobstructed.

[0048] When the effect is poor (possibly due to a malfunction of the dispersion component 9 or excessive material intake), the motor current of the cutting device 4 remains extremely high, or even triggers an overload alarm, and the pipeline flow rate drops significantly. This indicates that large, stubborn pieces of material are directly impacting the cutting device 4, resulting in poor dispersion and a risk of blockage.

[0049] When the effect is poor (the cutting device 4 is worn or its efficiency is reduced), the motor current of the cutting device 4 is abnormally low, the pipeline flow rate is reduced, and the size of the material being drawn back is significantly larger. This indicates that the blade of the cutting device 4 may be worn and dull, and cannot effectively cut the material. It needs to be repaired or replaced.

[0050] When the system determines that the effect is not good, it can automatically trigger adjustments. For example, when it detects that the motor current of the cutting device 4 is too high, it can automatically increase the speed and vibration intensity of the front dispersion component 9, or increase the flow rate of the spraying component to solve the problem at the front end.

[0051] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
