Description

Technical Field

[0001] The present invention belongs to the field of pipeline vibration control, and in particular relates to a penetrating pipeline vibration reduction device based on particle damping and an installation method thereof. Background Art

[0002] With the development of society and advancements in science and technology, many buildings and equipment are now inseparable from piping systems. However, the use of piping systems also presents numerous challenges. The operation of large-scale equipment can easily cause vibration and noise in the pipes. For example, the operation of water pumps can cause water pulsation in the pipes, resulting in "water hammer" at pipe bends. Furthermore, the vibration and noise generated by the equipment itself are transmitted to the piping system. Pipes are often installed throughout a building, often intersecting between floors. Vibration and noise from these pipes are then transmitted through the structures they pass through, disrupting people's work and daily lives. In particular, the use of piping systems in underground energy station rooms, where pipes are routed through walls and underground to the outside, presents a conflict between waterproofing and vibration and noise reduction. Existing pipe vibration dampers rarely offer both vibration reduction and waterproofing and fireproofing. Pipe installation in underground energy station rooms typically involves pre-determined holes in the walls during the civil engineering phase. Later, after the pipes are routed through the walls, they are sealed with cement concrete. After vibration and noise problems occur, even after vibration and noise reduction measures are taken inside the computer room, vibration and noise are still transmitted through the pipes to the walls and radiate outward, which is the "pipe noise" phenomenon.

[0044] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0046] Example 1:

[0047] like Figures 1 to 4As shown, the object 200 penetrated is an outdoor wall. Taking the basement energy room as an example, a particle damping-based penetrating pipe vibration reduction device provided in this embodiment includes: two damping flexible vibration reduction brackets 1, which are respectively sealed and fixedly sleeved at both ends of the penetrating pipe 100 through the wall, a connecting sleeve 2, which surrounds the wall-penetrating section of the penetrating pipe 100, and the two ends are respectively sealed and fixedly connected to the two damping flexible vibration reduction brackets 1, and the space between the connecting sleeve 2 and the outer wall of the penetrating pipe 100 is filled with fireproof material 3 to play a fire prevention role. The fireproof material 3 is surrounded by the connecting sleeve 2, the left and right damping flexible vibration reduction brackets 1 and the outer wall of the penetrating pipe 100 to ensure that the fireproof material 3 will not fall out, and through the sealed connection between the penetrating pipe 100 and the damping flexible vibration reduction bracket 1, the damping flexible vibration reduction bracket 1 and the connecting sleeve, the fireproof material 3 is prevented from being damp and affecting its performance, and moisture or water is also prevented from passing through the vibration reduction device, which has good waterproof performance. The interior of the connection section between the damping flexible vibration-damping bracket 1, the penetrating pipe 100 and the connecting sleeve 2 is filled with damping particles 14. The vibration reduction principle of the damping particles 14 can effectively solve the problem of high-frequency standing waves caused by vibration isolation. Particle damping vibration reduction technology is a new type of passive vibration control technology. Its main feature is to fill an appropriate number of metal or non-metallic tiny particles in the original cavity in the vibrating structure or the cavity formed by processing on the vibrating structure. When the structure vibrates, the particles and the particles and the hole walls continuously collide and rub, exchange momentum, and consume the energy of the structure. Adding damping particles 14 to the vibration transmission path will have a good effect on reducing the vibration amplitude of the structure. Reasonable filling of damping particles 14 in the cavities of the first base 11 and the second base 13 of the vibration reduction device can, on the one hand, effectively reduce the outward transmission of pipeline vibration, and on the other hand, effectively eliminate the high-frequency standing wave effect caused by the pipeline after vibration isolation. It has a wide range of applicability.

[0048] Furthermore, the damping flexible vibration-isolating bracket 1 includes a first base 11, a conical ring-shaped damping vibration isolator 12, and a second base 13. The first base 11 and the second base 13 are sealed and fixedly connected via the conical ring-shaped damping vibration isolator 12. The first base 11 is sealed and fixedly connected to the outer wall of the penetrating pipe 100, and the second base 13 is sealed and fixedly connected to the end of the damping flexible vibration-isolating bracket 1. The conical ring-shaped damping vibration isolator 12 is a shear-type, and the material of the conical ring-shaped damping vibration isolator 12 is rubber, silicone, an organic polymer elastic material, or an organic polymer composite elastic material. The first base 11 and the second base 13 are fixed to the conical ring-shaped damping vibration isolator 12 by vulcanization, bonding, riveting, or bolting. The surface of the conical ring-shaped damping vibration isolator 12 is smooth and / or non-smooth. The shear-type conical ring damping vibration isolator 12 is used as the main vibration isolation component, which has good vibration isolation, sound insulation and buffering effects. It can withstand multi-directional stress in conjunction with the first base 11 and the second base 13, and can effectively reduce the axial and radial low-frequency vibrations caused by pipeline vibration from being transmitted to the outside world through the object 200 passed through.

[0049] Furthermore, the first base 11 and the second base 13 each have at least two horizontal and / or vertical isolation cavities (not shown), and each isolation cavity is filled with damping particles 14 of the same and / or different characteristics, wherein the characteristics are the material, shape and size of the damping particles 14. The damping particles 14 are binary or multi-component particles formed by a mixture of one or more of iron-based particles, aluminum-based particles, nickel-based particles, tungsten-based particles, chromium-based particles, sodium-based particles, magnesium-based particles, manganese-based particles, calcium-based particles, copper-based particles, zinc-based particles, scandium-based particles, titanium-based particles, glass particles, oxide ceramic particles, carbide ceramic particles or glass ceramic particles. Specifically, the surface friction factor of the damping particles 14 is 0.01 to 0.99, the surface restitution coefficient is 0.01 to 1, and the density is 0.1 to 30 g / cm 3 The filling rate is 10% to 100%. The specific selection can be made according to actual needs, and the characteristics of each damping particle 14 can be the same or different to maximize the effect.

[0050] Furthermore, the insertion pipe 100 and the connecting sleeve 2 are fixed to the damping flexible vibration-isolating bracket 1 by welding, bonding, threaded connection, or expansion connection. In this embodiment, the insertion pipe 100 is fixed to the damping flexible vibration-isolating bracket 1 by welding, and the connecting sleeve 2 is fixed to the damping flexible vibration-isolating bracket 1 by threaded connection. The damping flexible vibration-isolating bracket 1 and the connecting sleeve 2 are fitted with one of smooth, friction, concave-convex, or stepped groove types. In this embodiment, the stepped groove type is used.

[0051] Furthermore, a waterproof vibration-damping pad 4 is provided between the mating surfaces of the flexible damping vibration-damping bracket 1 and the connecting sleeve 2. The flexible damping vibration-damping bracket 1 and the connecting sleeve 2 are fastened together by a fastener 5. Specifically, the fastener 5 is a bolt fastener, a pin fastener, a rivet fastener, or a glue fastener. In this embodiment, bolt fasteners are used for fastening. The waterproof vibration-damping pad 4 not only provides vibration damping but also waterproofing, further improving waterproof performance.

[0052] Furthermore, when the damping flexible vibration-isolating bracket 1 and the penetrable pipe 100 are sealed and fixed by welding, both damping flexible vibration-isolating brackets 1 are fully welded and sealed to the outer wall of the penetrable pipe 100 along the circumference of the penetrable pipe 100. The full welding ensures the sealing. In this embodiment, the welding points are all located on the right side of the first base 11.

[0053] Furthermore, the inner cavity of the first base 11 is cylindrical or polyhedron to adapt to penetrable pipes 100 of different shapes.

[0054] Furthermore, the materials of the first base 11 and the second base 13 are each selected from metal, metal composite material, or non-metallic material. Specifically, the metal is an aluminum alloy, titanium alloy, iron alloy, copper alloy, nickel alloy, lead alloy, manganese alloy, cobalt alloy, or tungsten alloy; the metal composite material is a multicomponent alloy of the aforementioned alloys; and the non-metallic material is a hard plastic or a hard organic material. This ensures that the first base 11 and the second base 13 have high load capacity and deformation resistance, thereby improving their lifespan.

[0055] like Figures 5 to 12 As shown, this embodiment also provides a method for installing a penetrating pipeline vibration reduction device based on particle damping, comprising the following steps:

[0056] S1: An elastic support 6 for supporting the penetrable pipe 100 is set. An elastic support 6 for supporting the penetrable pipe 100 is set at a certain distance from the wall through which the original penetrable pipe 100 passes. The elastic support 6 is located indoors to ensure that after the original penetrable pipe 100 is cut off, except for the cut-off part, the rest of the penetrable pipe 100 can remain in place.

[0057] S2: Drill a through hole 7, expand the wall around the penetrable pipe 100 and make the hole pass through the wall. Specifically, expand the hole along the circumference of the penetrable pipe 100. The diameter of the through hole 7 is 1.5 times the outer diameter of the penetrable pipe 100.

[0058] S3: Cutting off a specific length of the penetrable pipe 100. The cutting position is between the wall and the elastic support 6. The length of the cut penetrable pipe 100 depends on the on-site construction conditions.

[0059] S4: Install the vibration damping device and seal and fix the vibration damping device at the perforation.

[0060] Specifically, the following steps are included:

[0061] S41: Insert one of the damping flexible vibration-isolating brackets 1 from the cut end into the penetrable pipe 100 to the left side of the wall, and seal and fix the damping flexible vibration-isolating bracket 1 on the outer wall of the penetrable pipe 100 along the circumference of the penetrable pipe 100.

[0062] S42: Insert the connecting sleeve 2 into the penetrable pipe 100 and seal and fix the left end to the damping flexible vibration-damping bracket 1 located on the left side of the wall. Specifically, the left end of the connecting sleeve 2 is matched with the second base 13 of the damping flexible vibration-damping bracket 1 in a stepped groove, and a waterproof vibration-damping pad 4 is provided in the middle of the matching surface. Then, the second base 13 of the damping flexible vibration-damping bracket 1 and the connecting sleeve 2 are fastened by bolt fasteners 5.

[0063] S43: Fill fireproof material 3 between the connecting sleeve 2 and the outer wall of the penetrated pipe 100, then insert another damping flexible vibration-damping bracket 1 into the penetrated pipe 100 from the truncated end and seal and fix it with the right end of the connecting sleeve 2. The damping flexible vibration-damping bracket 1 is located on the right side of the wall. Specifically, the left end of the second base 13 of the damping flexible vibration-damping bracket 1 is matched with the right end of the connecting sleeve 2 in a stepped groove, and a waterproof vibration-damping pad 4 is provided in the middle of the matching surface. Then, the second base 13 of the damping flexible vibration-damping bracket 1 and the connecting sleeve 2 are fastened by bolt fasteners 5. Finally, the damping flexible vibration-damping bracket 1 is fully welded and sealed along the circumference of the penetrated pipe 100 and fixed on the outer wall of the penetrated pipe 100.

[0064] S5: Reconnecting and restoring the cut penetrable pipe 100. The restoration can be achieved by fully welding the cut penetrable pipe 100 to its original location, or by using a sealing connection method such as a flange to ensure pipe connectivity.

[0065] S6: Fill and seal the space between the vibration damping device and the perforation 7, fill the perforation 7 with cement concrete 8 until it is restored to its original state to ensure waterproof requirements.

[0066] Example 2:

[0067] like Figure 13 As shown, the difference between this embodiment and the first embodiment is that the object 200 penetrated is an indoor partition wall, and two elastic supports 6 for supporting the penetrating pipe 100 are set at a certain distance from the partition wall penetrated by the original penetrating pipe 100. The two elastic supports 6 are respectively located indoors and outdoors. After installing the vibration reduction device, the sealing material 9 is used for filling and leveling. In this embodiment, sealing foam is used for filling.

[0068] After the installation of the particle damping-based penetrating pipeline vibration reduction device of the present invention, a vibration test is performed on the pipeline and the object 200 through which the pipeline is penetrated to obtain the vibration spectrum curves before and after the vibration reduction. Figure 14 , curve a in the figure is the vibration spectrum curve before the vibration damping device is installed, and curve b in the figure is the vibration spectrum curve after the vibration damping device is installed. Therefore, it can be seen that the particle damping-based penetrating pipe vibration damping device of the present invention can effectively reduce the axial and radial low-frequency vibrations caused by pipeline vibration and transmitted to the outside world through the object 200 passed through. After the installation of the vibration damping device, the vibration is almost 0. Utilizing the vibration damping principle of the damping particles 14, the problem of high-frequency standing waves caused by vibration isolation can be effectively solved, and it has a good vibration damping effect; and it can effectively solve the problem of conflict between waterproofing and vibration and noise reduction of indoor and outdoor object penetrating pipes 100. It has a wide range of applicability.
