Description

Technical Field

[0001] The utility model belongs to the technical field of protective devices, and in particular relates to a pipeline entity protective device. Background Art

[0002] In modern industry and urban construction, pipeline systems are an important part of infrastructure, involving multiple fields such as electricity, communications, water supply and drainage. These pipelines not only need to stably transmit energy and information in a complex and changing environment, but also have to face the challenges of natural disasters, human factors and wear and tear caused by long-term operation. Therefore, the physical protection device of the pipeline is particularly important. It not only affects the safe operation of the system, but also affects the maintenance cost and service life. Traditional pipeline protection devices mostly focus on the durability of materials and the stability of structures, such as using metal casings, hard plastic casings, etc. to resist physical impact, corrosion and environmental erosion. However, with the advancement of technology and the improvement of safety standards, the requirements for pipeline protection have far exceeded the scope of simple physical protection, especially for those high-level transmission systems that are sensitive to vibration, such as high-voltage cables, fiber-optic communication lines, etc., traditional protection methods have shown their limitations.

[0003] In the design of traditional protective devices, the focus is often on the strength and durability of materials, such as the use of shells or casings made of metal, hard plastic and other materials, which are designed to resist physical damage such as collision, extrusion and environmental erosion. Although these protective measures perform well in static protection, they are powerless in the face of dynamic impact. Mechanical vibration, whether it comes from the vibration of running mechanical equipment, vehicles, or natural factors such as wind, can produce continuous stress fluctuations inside the pipeline. This long-term low-frequency vibration will cause cumulative damage to internal components such as wires and cables, induce metal fatigue, accelerate material aging, and ultimately may cause wire breakage, signal attenuation and even system failure. In extreme cases, such as earthquakes, this defect is even more fatal. The strong instantaneous impact force is enough to make traditional protective devices that lack effective shock absorption design fail, causing direct damage to the pipeline and large-scale service interruption.

[0004] In addition, the shortcomings of traditional protection methods are also reflected in the static nature of their design. In actual applications, pipeline laying environments are diverse, with different terrain and geological conditions, and traditional protection devices often lack targeted shock-absorbing designs and cannot adapt well to the needs of different scenarios. For example, on soft soil foundations, pipelines are more likely to be damaged by surface liquefaction caused by earthquakes; pipelines on elevated roads or bridges face greater risks of wind vibration. These situations require protective devices to have higher dynamic adaptability and flexibility, which traditional methods often fail to take into account. Utility Model Content

[0005] In view of this, the utility model provides a pipeline entity protection device, which increases the contact area through a spiral structure, solves the problem of limited shock absorption capacity of traditional protection means, and protects the pipeline from earthquakes or mechanical vibrations.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a pipeline entity protection device, including a pipeline, wherein a cushion body is wrapped on the outside of the pipeline support point, the cushion body is a continuous spiral structure, a support frame is arranged below the cushion body, the inner surface of the support frame is designed with a guide groove matching the cushion body, the support frame serves as an intermediary between the cushion body and the pipeline support point, the support frame is provided with a reserved hole, and the cushion body and the reserved hole of the support frame are detachably connected through a fastening assembly.

[0008] On the basis of the above technical solution, a pipeline entity protection device of the utility model can also be improved as follows:

[0009] Wherein, the number of spiral turns of the cushion body is not less than 3 turns.

[0010] The spiral pad body is directly wrapped around the outer surface of the pipeline due to its design. It does not involve a fixed connection in the traditional sense. Instead, it relies on its own spiral structure to fit the pipeline, achieving a physical wrapping and contact, thereby achieving a shock-absorbing effect.

[0011] Furthermore, the support frame is an annular structure, the support frame is composed of continuous circular rings, and the diameter of the support frame is increased by 5% to 10% based on the outer diameter of the pipeline.

[0012] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the annular structure is composed of a continuous circular ring without interrupted parts, and can evenly disperse various forces applied to the pipeline, such as gravity, vibration or impact. This design is particularly suitable for situations where the pipeline support points need to be fully protected, ensuring the continuity and balance of force transmission.

[0013] Furthermore, the support frame is a semi-annular structure, one side of the support frame is connected to the installation base through the fastening assembly, and the other side is in contact with the pipeline, and interface mechanisms are provided at both ends of the support frame.

[0014] Furthermore, there are multiple fastening assemblies, and the fastening assemblies include bolts, nuts and washers.

[0015] Furthermore, the bolts are distributed at equal intervals along the support frame, and the intervals do not exceed 1 / 8 of the circumference of the support frame.

[0016] Furthermore, the thickness of the pad body is between 20 and 50 mm.

[0017] Furthermore, the pad is made of rubber or foam material with a density of 0.1 to 0.5 g / cm 3 within the range.

[0018] The spiral pad is made of rubber or foam material with high shock absorption performance, including the following categories:

[0019] Polyurethane foam: Polyurethane foam is a very flexible material that can be adjusted in hardness and density as needed. It can be open-cell or closed-cell. Closed-cell structures are particularly good at waterproofing and insulation, while open-cell structures are better at sound absorption and vibration reduction. Polyurethane foam is widely used in the automotive, furniture, packaging and construction industries.

[0020] Rubber-based foams: This category includes materials such as natural rubber, EPDM and butyl rubber. They are often used to make weatherstrips, gaskets and shock absorbers, especially in environments that require resistance to ageing, chemicals and extreme temperatures. EPDM foam is particularly suitable for outdoor use because of its excellent weather resistance.

[0021] Polystyrene foam: Although polystyrene foam is mainly known for its thermal insulation properties, its light weight and certain shock absorption capabilities also make it a choice for packaging materials and certain shock absorption applications. XPS (extruded polystyrene) has higher compressive strength and water vapor barrier properties than EPS (expanded polystyrene).

[0022] Polyethylene and polypropylene foams: These two plastic foams are light, flexible, and have good chemical and water resistance. They can be designed with different densities to meet specific shock absorption or cushioning needs and are commonly used in packaging, sports equipment, and industrial shock absorption.

[0023] Silicone rubber foam: Silicone rubber foam materials are known for their superior heat resistance, cold resistance, weather resistance and good mechanical properties, and are suitable for high-end shock absorption and insulation applications such as aerospace, electronic equipment and medical equipment.

[0024] Furthermore, the support frame is made of stainless steel or high-strength aluminum alloy.

[0025] Furthermore, the interface mechanism includes a snap-on, a threaded connection or a quick-release pin.

[0026] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: for the semi-ring structure, both ends are designed with precise interface mechanisms, such as snap-fit, threaded connection or quick-release pins, to ensure that the two semi-rings can be quickly and firmly connected together to form a stable whole, while retaining a certain adjustment room to adapt to the fine-tuning requirements of on-site installation.

[0027] Compared with the prior art, the beneficial effects of the pipeline entity protection device provided by the utility model are:

[0028] Excellent shock absorption effect: The spiral pad design uses the elasticity of the material itself and the special structural form to effectively absorb and disperse external impact and vibration energy, significantly reducing the dynamic stress transmitted to the conductor and extending the service life of the pipeline. It is particularly suitable for high-level transmission systems that are sensitive to vibration;

[0029] Convenient installation and maintenance: The support frame is designed with a quick connection interface mechanism, such as snap-on, threaded connection or quick-release pin, so that the two semi-circular support frames can be quickly and firmly spliced ​​together, while leaving room for fine-tuning to meet the fine-tuning requirements of on-site installation, greatly reducing the difficulty and cost of installation and maintenance;

[0030] Wide range of environmental adaptability: The selected high shock-absorbing rubber or foam material has good temperature resistance, weather resistance and chemical corrosion resistance, and can maintain good performance even in harsh environments, improving the environmental adaptability and durability of the overall device.

[0037] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.

[0038] like Figure 1 , Figure 2As shown, it is a first embodiment of a pipeline entity protection device provided by the utility model. In this embodiment, it includes a pipeline 10, wherein a cushion body 20 is wrapped on the outside of the support point of the pipeline 10, and the cushion body 20 is a continuous spiral structure. A support frame 30 is arranged below the cushion body 20, and the inner surface of the support frame 30 is designed with a guide groove matching the cushion body 20. The support frame 30 serves as an intermediary between the cushion body 20 and the support point of the pipeline 10. The support frame 30 is provided with a reserved hole, and the reserved holes of the cushion body 20 and the support frame 30 are detachably connected through a fastening assembly 40.

[0039] When in use, the pipeline body is located in the center, the spiral pad body is close to the pipeline surface and surrounds the key support points, and the support frame follows closely below, providing a stable installation platform for the spiral pad body, while the fastening assembly is like a bridge, firmly connecting the spiral pad body, the support frame and even the pipeline body with the external fixed structure. This multi-level structural design ensures that when the pipeline is subjected to external vibration or impact, the buffering effect of the spiral pad body can effectively disperse the energy and protect the pipeline from damage.

[0040] Among them, in the above technical solution, the number of spiral turns of the pad body 20 is not less than 3 turns.

[0041] Furthermore, in the above technical solution, the support frame 30 is an annular structure, the support frame 30 is composed of continuous circular rings, and the diameter of the support frame 30 increases by 5% to 10% based on the outer diameter of the pipeline 10.

[0042] When in use, first wrap the spiral gasket around the pipeline and place it on the support frame, then pass the bolts through the support frame, spiral gasket (if the design allows penetration) and possible pipeline fixing brackets through the pre-set fastening points, and tighten them with nuts after adding gaskets. This not only fixes the spiral gasket, but also ensures the tight combination of the entire device and the pipeline body, forming a solid overall structure that effectively resists external forces.

[0043] Furthermore, in the above technical solution, there are multiple fastening assemblies 40, and the fastening assemblies 40 include bolts, nuts and washers.

[0044] Furthermore, in the above technical solution, the bolts are distributed at equal intervals along the support frame 30 , and the intervals do not exceed 1 / 8 of the circumference of the support frame 30 .

[0045] Furthermore, in the above technical solution, the thickness of the pad body 20 is between 20 and 50 mm.

[0046] Furthermore, in the above technical solution, the pad body 20 is made of rubber or foam material with a density of 0.1 to 0.5 g / cm 3 within the range.

[0047] Furthermore, in the above technical solution, the support frame 30 is made of stainless steel or high-strength aluminum alloy.

[0048] Furthermore, in the above technical solution, the interface mechanism includes a snap-on, a threaded connection or a quick-release pin.

[0049] 1. Snap-on interface mechanism:

[0050] Design description: Each semi-circular support frame is designed with a complementary flange and groove structure at the end, that is, a raised buckle at one end and a matching groove at the other end. The buckle and the groove match in size, and the two can fit tightly and are easy to connect manually.

[0051] Implementation details: The snap-fit ​​design includes a preset elastic element, such as a built-in spring or an elastic plastic sheet, to provide the necessary clamping force to ensure a secure connection. The snap-fit ​​also has a locking mechanism, such as a rotating lock or a push-pull locking pin, which can be locked once in place to prevent accidental separation.

[0052] 2. Threaded connection interface:

[0053] Design description: The edges of both ends of the semi-circular support frame are equipped with internal and external threads, one end is an external thread and the other end is a corresponding internal thread. Through the rotation operation, the two semi-rings can be screwed together.

[0054] Implementation details: The thread design uses a self-locking thread type, such as trapezoidal thread or serrated thread, to improve the reliability of the connection. To facilitate installation, the threaded part can be pre-lubricated and equipped with positioning pins or guide holes to ensure accurate alignment. In addition, the fastening device can be designed with a handle or a wrench to facilitate force application.

[0055] 3. Quick-release pin interface:

[0056] Design description: There are corresponding small holes at both ends of the semi-circular frame for inserting quick-release pins. The pins are designed with barbs or expansion heads at both ends. After being inserted into the holes, they are expanded by rotation or hammering, so that they are fixed in the holes.

[0057] Implementation details: The hole design needs to take into account the expansion size of the pin to ensure that the frame will not be damaged while being tightened. The pin material is selected from high-strength alloy to ensure sufficient tensile strength and durability. In addition, the quick-release pin can be designed to be detachable and equipped with special tools for easy on-site adjustment or disassembly.

[0058] like Figure 1 , Figure 3As shown, it is a second embodiment of a pipeline entity protection device provided by the utility model. In this embodiment, it includes a pipeline 10, wherein a cushion body 20 is wrapped on the outside of the support point of the pipeline 10, and the cushion body 20 is a continuous spiral structure. A support frame 30 is arranged below the cushion body 20, and the inner surface of the support frame 30 is designed with a guide groove matching the cushion body 20. The support frame 30 serves as an intermediary between the cushion body 20 and the support point of the pipeline 10. The support frame 30 is provided with a reserved hole, and the reserved holes of the cushion body 20 and the support frame 30 are detachably connected through a fastening assembly 40.

[0059] When in use, the pipeline body is located in the center, the spiral pad body is close to the pipeline surface and surrounds the key support points, and the support frame follows closely below, providing a stable installation platform for the spiral pad body, while the fastening assembly is like a bridge, firmly connecting the spiral pad body, the support frame and even the pipeline body with the external fixed structure. This multi-level structural design ensures that when the pipeline is subjected to external vibration or impact, the buffering effect of the spiral pad body can effectively disperse the energy and protect the pipeline from damage.

[0060] Among them, in the above technical solution, the number of spiral turns of the pad body 20 is not less than 3 turns.

[0061] The support frame 30 is a semi-annular structure. One side of the support frame 30 is connected to the installation base through a fastening assembly 40 , and the other side is in contact with the pipeline 10 . Interface mechanisms are provided at both ends of the support frame 30 .

[0062] When a semi-ring structure is used, the support frame is in the shape of a half ring, designed for specific installation environments or pipeline layouts, such as when the pipeline passes by the edge of a wall or an existing structure. One side of the semi-ring structure is connected to the installation base (such as a wall, bracket or other fixed structure) through a fastening component, and the other side is directly or indirectly in contact with the pipeline, and is connected to another semi-ring support frame that may exist through a carefully designed interface to form a closed protection circle. The semi-ring design is more flexible and facilitates installation and maintenance in confined spaces.

[0063] Furthermore, in the above technical solution, there are multiple fastening assemblies 40, and the fastening assemblies 40 include bolts, nuts and washers.

[0064] Furthermore, in the above technical solution, the bolts are distributed at equal intervals along the support frame 30 , and the intervals do not exceed 1 / 8 of the circumference of the support frame 30 .

[0065] Furthermore, in the above technical solution, the thickness of the pad body 20 is between 20 and 50 mm.

[0066] Furthermore, in the above technical solution, the pad body 20 is made of rubber or foam material with a density of 0.1 to 0.5 g / cm 3 within the range.

[0068] Furthermore, in the above technical solution, the interface mechanism includes a snap-on, a threaded connection or a quick-release pin.

[0069] Specifically, the principle of the utility model is:

[0070] Material selection and design: By selecting materials with high elasticity and high shock absorption performance, such as polyurethane foam with specific density and hardness, these materials can effectively absorb and dissipate energy when subjected to external forces, converting it into heat energy or internal strain energy, thereby reducing the transfer of energy to the conductors;

[0071] Mechanical advantages of spiral pads: The spiral structure not only increases the surface area in contact with the wire, but also utilizes the continuous support points on the spiral path to form a multi-point load dispersion mechanism. When external forces act, the spiral pad absorbs energy through local deformation while maintaining the stability of the overall structure. This nonlinear shock absorption mechanism effectively reduces the direct impact of the wire;

[0072] Structural reinforcement of the support frame: As a load-bearing skeleton, the support frame ensures the rigidity and stability of the entire device through precisely calculated cross-sectional dimensions and material selection. The combination of the frame and the spiral pad body utilizes the principle of force transmission and distribution in mechanics to reasonably distribute external loads and avoid damage caused by concentrated stress.
