[0002] In many water delivery systems and hydropower projects at home and abroad, moor mud bivalve (commonly known as freshwater shellfish) has become a widely existing fouling organism, which attaches to the inner wall of the pipeline at high density, causing serious fouling, blockage and corrosion. In view of this biofouling problem, the magnetic heat clam cleaner has great potential and broad application prospects. It generates a strong alternating magnetic field by electromagnetic induction to heat superparamagnetic nanoparticles (SMNP), thereby killing moor mud bivalve larvae or adult shellfish. However, the magnetic heat clam cleaner usually acts on the inside of the water delivery pipeline and is prone to violent collision with the water delivery pipeline during operation, which may cause damage to the magnetic heat clam cleaner itself and the water delivery pipeline. In particular, in the case of large water flow fluctuations or complex water delivery pipeline environments, the magnetic heat clam cleaner itself and the water delivery pipeline are more likely to be damaged.

[0003] Existing magnetic heat clam cleaners are designed with hard structures and lack anti-collision protection measures. In addition, mechanical impact during pressure changes inside the water delivery pipeline or external equipment maintenance may also adversely affect the device structure. SUMMARY

[0044] In some embodiments, the outer buffer layer module 11 comprises, in sequence from outside to inside in the radial direction, an anti-friction layer 111, an outer buffer layer 112, and an impact-resistant layer 113. The outer periphery of the anti-friction layer 111 is used to abut against the inner wall of the water conveying pipeline, has very strong wear resistance, and is mainly used to prevent wear caused by long-term friction with the inner wall of the water conveying pipeline; the outer buffer layer 112 can not only absorb greater impact energy, disperse pressure, and slow down the impact of external force on the magnetic heat clam clearing device and the water conveying pipeline, but also can withstand greater mechanical impact and can resist greater mechanical collisions, thereby protecting the magnetic heat clam clearing device and the water conveying pipeline from being damaged under severe vibration or strong external force; the impact-resistant layer 113 has high elasticity, is mainly used to absorb the initial impact energy when the impact occurs for the first time, can play a shock-absorbing role when the magnetic heat clam clearing device collides with the water conveying pipeline, and can also adapt to changes in external temperature and maintain elasticity.

[0045] In some embodiments, the anti-friction layer 111 is a polyethylene anti-friction layer or a ceramic reinforced material anti-friction layer. The polyethylene anti-friction layer is composed of ultra-high molecular weight polyethylene material (UHMWPE), which can greatly reduce the friction coefficient and maintain smooth operation between the device and the inner wall of the water conveying pipeline. The ceramic reinforced material anti-friction layer is composed of ceramic reinforced material. The thickness of the anti-friction layer 111 is 1-3 mm. The anti-friction layer 111 has very strong wear resistance and can effectively prevent wear caused by long-term friction with the inner wall of the water conveying pipeline.

[0046] In some embodiments, the outer buffer layer 112 comprises a semi-hard buffer layer 1121 and a foam buffer layer 1122 arranged in the radial direction. The semi-hard buffer layer 1121 is located between the anti-friction layer 111 and the foam buffer layer 1122, and the foam buffer layer 1122 is located between the semi-hard buffer layer 1121 and the impact-resistant layer 113. The semi-hard buffer layer 1121 has a certain hardness, can withstand greater mechanical impact, is used to resist greater mechanical collisions, and protects the magnetic heat clam clearing device and the water conveying pipeline from being damaged under severe vibration or strong external force. The foam buffer layer 1122 has the characteristics of light weight and impact resistance, has good water resistance and corrosion resistance, can effectively absorb greater impact energy, disperse pressure, and slow down the impact of external force on the device.

[0047] In some embodiments, the semi-hard buffer layer 1121 is a polycarbonate material buffer layer or a reinforced fiber composite material buffer layer, i.e., the polycarbonate material buffer layer is composed of polycarbonate material, and the reinforced fiber composite material buffer layer is composed of reinforced fiber composite material. Such materials have a certain degree of hardness and can withstand a large mechanical impact. The thickness of the semi-hard buffer layer 1121 is 2-4 mm. The semi-hard buffer layer 1121 can resist a large mechanical impact and protect the magnetic heat clamshell device and the water delivery pipeline from being damaged under severe vibration or strong external force. The high impact resistance of polycarbonate material can ensure that it will not break under severe impact.

Such materials have the characteristics of light weight, impact resistance, good water resistance, and corrosion resistance. The thickness of the foam buffer layer 1122 is about 5-10 mm. The foam buffer layer 1122 can effectively absorb a larger impact energy, disperse the pressure, and reduce the impact of external force on the equipment.

[0049] In some embodiments, the impact-resistant layer 113 is a rubber layer or a silicone layer, the rubber layer is made of high-strength rubber material, and the silicone layer is made of high-strength silicone material.

The impact-resistant layer 113 has high elasticity and can absorb the impact when the pipeline collides slightly. It can also adapt to changes in external temperature and maintain elasticity.

[0050] The above-mentioned external buffer layer module 11 adopts a multi-layer structure design and mainly uses high-strength rubber, polyurethane, or other impact-resistant materials. When the anti-collision structure 1000 is distributed at both ends of the magnetic heat clamshell device solenoid 22, the external buffer layer 112 can absorb external impact force and vibration. The thickness and material selection of the external buffer layer module 11 are adjusted according to the water delivery pipeline environment and the use conditions of the equipment. By optimizing the material ratio, it is ensured that the buffer layer 112 can effectively absorb energy and reduce direct damage to the equipment under strong water impact or external mechanical impact.

[0051] In some embodiments, the elastic buffer layer module 12 comprises a metal spring support layer 121, an air bag buffer layer 122 and a flexible shock absorbing pad layer 123 arranged in sequence from outside to inside. The metal spring of the metal spring support layer 121 can be compressed and absorb impact energy when subjected to external force, and then release energy by restoring to its original shape, avoiding hard collision of the magnetic heat clam clearer with the water conveying pipeline, and suitable for main protection under large impact force. The air bag buffer layer 122 can buffer by air pressure inside the air bag, suitable for large amplitude vibration and impact absorption, and the air bag buffer layer 122 has good elastic recovery, and can quickly recover to its original shape after the impact disappears. The inner periphery of the flexible shock absorbing pad layer 123 abuts against the outer periphery of the framework 21 of the magnetic heat clam clearer body 2000, mainly plays a shock absorbing role, can relieve the impact force of the magnetic heat clam clearer and the water conveying pipeline under light vibration, can softly disperse instantaneous vibration or slight impact, and reduces damage to the magnetic heat clam clearer and the water conveying pipeline.

[0052] In some embodiments, the metal spring support layer 121 is a spiral compression spring support layer or a leaf spring support layer, wherein the spiral compression spring support layer is composed of a spiral compression spring, and the leaf spring support layer is composed of a leaf spring. The metal spring support layer 121 usually uses high-strength steel material, and the stiffness and diameter of the metal spring are adjusted according to the environment of the water conveying pipeline. The metal spring support layer 121 can be compressed and absorb impact energy when subjected to external force, and then release energy by restoring to its original shape, avoiding hard collision of the equipment with the pipeline. The design of this layer is suitable for main protection under large impact force.

[0053] In some embodiments, the air bag buffer layer 122 is a flexible air bag buffer layer 122 or an inflatable shock absorbing pad, and the thickness of the air bag buffer layer 122 is 5-8 mm. The air bag buffer layer 122 can buffer by air pressure inside the air bag, suitable for large amplitude vibration and impact absorption, and the air bag buffer layer 122 has good elastic recovery, and can quickly recover to its original shape after the impact disappears.

[0054] In some embodiments, the flexible shock absorbing pad is a rubber pad, and the thickness of the flexible shock absorbing pad is 2-3 mm. The inner periphery of the flexible shock absorbing pad layer 123 abuts against the outer periphery of the framework 21 of the magnetic heat clam clearer body 2000, mainly plays a shock absorbing role, can relieve the impact force of the magnetic heat clam clearer and the water conveying pipeline under light vibration, can softly disperse instantaneous vibration or slight impact, and reduces damage to the magnetic heat clam clearer and the water conveying pipeline.

[0055] The elastic buffer layer module 12 is located between the magnetic heat clam cleaner skeleton 21 and the external buffer layer module 11, and effectively absorbs the vibration and impact force generated during operation by using components such as springs, shock pads or air bags. The elastic buffer layer module 12 ensures that the magnetic heat clam cleaner and the water pipeline can relieve the impact through elastic displacement or deformation when subjected to external impact, thereby avoiding damage to the magnetic heat clam cleaner and the water pipeline. The stiffness and elastic coefficient of the elastic buffer layer module 12 can be adjusted according to the impact strength in different water pipeline environments to ensure stable operation of the magnetic heat clam cleaner and the water pipeline.

[0056] The anti-collision structure 1000 of the utility model has the comprehensive performance of the multi-layer protection structure. Specifically, on the one hand, it has the synergistic effect of the multi-layer structure: each layer of material forms a layer-by-layer energy absorption buffer system according to its different physical properties. When the magnetic heat clam cleaner hits the pipe wall of the water pipeline, the impact-resistant layer 113 of the external buffer layer module 11 first absorbs part of the energy, while the foam buffer layer 1122 continues to absorb and disperse the remaining impact, and the semi-hard buffer layer 1121 and the anti-friction layer 111 further provide mechanical strength and wear resistance protection; the layers of materials in the elastic buffer layer module 12 form a complete anti-seismic and anti-collision system through the combination of air bags, shock pads and springs; on the other hand, it has multi-working-condition adaptability: the multi-layer buffer design can effectively cope with various impacts in water flow fluctuations, mechanical vibrations and external maintenance operations, ensuring that the magnetic heat clam cleaner and the water pipeline system remain stable in complex working conditions, especially in high-impact environments, the energy absorption and dispersion capacity of the multi-layer structure can prevent the magnetic heat clam cleaner and the water pipeline from being damaged due to excessive vibration.

[0057] The installation process of the anti-collision structure 1000 of the utility model is simple, and the modular design of the external buffer layer module 11 and the elastic buffer layer module 12 facilitates quick installation in existing water pipeline systems. The magnetic heat clam cleaner does not need frequent maintenance after installation, and the material of the elastic buffer layer module 12 is durable and can be used for a long time without failure. Regular inspection and replacement of buffer materials can ensure the continuous protection effect of the magnetic heat clam cleaner and the water pipeline. In addition, by monitoring the operating state of the magnetic heat clam cleaner and the water pipeline, potential collision or damage problems can be found and solved in time, prolonging the service life of the magnetic heat clam cleaner and the water pipeline.
