They ensure the efficient and stable transmission of materials and energy, greatly promoting the operation and development of society.
[0003] Currently, to ensure stable temperature of the substances inside pipelines and reduce heat loss or the impact of external temperature on the medium, most pipelines use insulation layers for heat preservation. However, the materials used in traditional insulation layers, such as asbestos, cause serious environmental pollution during production, use, and post-treatment. Once released into the air, asbestos fibers are not only difficult to degrade but also spread with air currents, causing long-term and incalculable damage to the ecological environment. They also pose a serious threat to human health, easily leading to a series of health problems such as lung diseases. Therefore, developing an environmentally friendly, efficient, and practical pipeline insulation device is urgently needed. Utility Model Content

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :
[0035] Example 1:
[0036] This embodiment provides a pipe insulation device, including a pipe body 1, and further including:
[0037] The assembled protective cover 2 is detachably covered on the outside of the tube body 1;
[0038] The split-type heat insulation sleeve is located inside the assembled protective cover 2. The split-type heat insulation sleeve includes multiple heat insulation sleeves 30 that wrap around the outside of the tube body 1 and are evenly arranged along the length of the tube body 1, an inlet pipe 31 and an outlet pipe 32 that are respectively connected to the two outermost heat insulation sleeves 30, and a magnetic suction assembly 33 for detachable connection between the heat insulation sleeves 30. The heat insulation sleeve 30 has a dual structure design.
[0039] The inlet pipe 31 and outlet pipe 32 are regulated by external temperature control equipment to regulate the internal temperature of the pipes.
[0040] The assembled protective cover 2 protects the pipe body 1 and the split heat insulation sleeve, preventing damage from external factors such as mechanical damage and rainwater erosion, and also helps to maintain the stability of the heat insulation sleeve.
[0041] The split-type heat insulation sleeve is used to reduce heat transfer between the pipe body 1 and the external environment, thus playing a role in heat insulation and heat preservation. At the same time, the internal temperature of the pipe can be adjusted as needed.
[0042] The heat insulation sleeve 30 is the core component for achieving pipe insulation. It directly wraps around the outside of the pipe body 1, reducing heat exchange between the pipe body 1 and the external environment, thus providing insulation or cold insulation. Simultaneously, its internal structure can accommodate temperature-controlled fluids, assisting in regulating the temperature of the pipe body 1. The heat insulation sleeve 30 adopts a dual-structure design, generally ring-shaped, which can tightly fit the circumference of the pipe body 1 to ensure good insulation performance. The heat insulation sleeves 30 are evenly arranged along the length of the pipe body 1, completely wrapping around the outside of the pipe body 1, achieving full-length heat insulation protection for the pipe body 1.
[0043] Inlet pipe 31 and outlet pipe 32 are channels connecting the insulation sleeve 30 to external temperature control equipment, used to transport temperature-controlled fluids such as hot water, cold water, or other coolants. By controlling the inflow and outflow of the temperature-controlled fluid, precise temperature regulation of the internal temperature of the pipe body 1 is achieved. Inlet pipe 31 and outlet pipe 32 are typically tubular structures, connected to the two outermost insulation sleeves 30 respectively, ensuring that the temperature-controlled fluid can enter and flow out of the split-type insulation sleeve. Inlet pipe 31 and outlet pipe 32 can be sealed to the insulation sleeve 30 using methods such as welding, flange connection, or sealant to prevent leakage of the temperature-controlled fluid.
[0044] The magnetic assembly 33 is used to achieve a detachable connection between the heat insulation sleeves 30. It makes the installation and removal of the heat insulation sleeves 30 simpler and faster, while ensuring a tight connection between the heat insulation sleeves 30 and reducing heat leakage.
[0045] Example 2:
[0046] This embodiment provides a pipe insulation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0047] The assembled protective cover 2 includes:
[0048] The first cover 20 has an assembly structure 22 for both the fixing part and the docking part;
[0049] The second cover 21 has a fixing part and a docking part that are engaged with the assembly structure 22 of the first cover 20.
[0050] An elastic bending portion 23 is provided between the fixing portions of the first cover 20 and the second cover 21. The elastic bending portion 23 allows for elastic deformation during installation to wrap around the tube body 1.
[0051] The first cover 20 is part of the assembled protective cover 2. It cooperates with the second cover 21 to jointly wrap around the tube 1 and the heat insulation sleeve, providing protection. The assembly structure 22 of its fixing part and docking part is used to connect with the second cover 21. The first cover 20 is usually a semi-cylindrical structure. Its fixing part and docking part have specific assembly structures 22, which correspond to the second cover 21 and together wrap around the outside of the tube 1. After the two are spliced together, they form a complete cylindrical protective cover.
[0052] The second cover 21 symmetrically fits with the first cover 20 to form an assembled protective cover 2, protecting the tube 1 and the heat insulation sleeve. Its fixing and docking parts have a snap-fit structure that engages with the assembly structure 22 of the first cover 20 to achieve connection between the two. The second cover 21 is also a semi-cylindrical structure, complementary in shape to the first cover 20, and its fixing and docking parts are adapted to the assembly structure 22 of the first cover 20.
[0053] The elastic bending portion 23 connects the fixing portions of the first cover 20 and the second cover 21. During installation of the protective cover, elastic deformation is allowed, enabling the first cover 20 and the second cover 21 to open and wrap around the tube 1. After installation, it returns to its elasticity, ensuring a tight fit of the protective cover. The elastic bending portion 23 is typically a columnar structure with a certain degree of elasticity and can be connected to the fixing portions of the first cover 20 and the second cover 21 by means of bonding, vulcanization, etc.
[0054] This embodiment utilizes the elastic deformation characteristics of the elastic bending portion 23 to allow the first cover 20 and the second cover 21 to open during installation, facilitating the wrapping of the tube 1. After installation, the elastic bending portion 23 returns to its elasticity, and the first cover 20 and the second cover 21 are snapped together by the assembly structure 22 to form a stable protective cover that protects the tube 1 and the heat insulation sleeve.
[0055] Example 3:
[0056] This embodiment provides a pipe insulation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0057] The assembly structure 22 includes:
[0058] Assembly table 220 is located at the fixing part of the first cover 20;
[0059] The mounting slot 221 is located at the docking part of the first cover 20;
[0060] The second cover 21 is provided with a structure that engages with the assembly plate 220 and the assembly slot 221.
[0061] The assembly structure 22 is used to achieve a detachable connection between the first cover 20 and the second cover 21, ensuring sufficient stability and sealing of the protective cover after installation. The assembly structure 22 includes an assembly latch 220 located at the fixing part of the first cover 20 and an assembly slot 221 at the mating part. The assembly latch 220 is typically a raised structure, and the assembly slot 221 is a corresponding recessed structure. The second cover 21 has a structure that engages with the assembly latch 220 and the assembly slot 221, thereby connecting the first cover 20 and the second cover 21 through this engagement.
[0062] Example 4:
[0063] This embodiment provides a pipe insulation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0064] Both the first cover 20 and the second cover 21 adopt a double-layer composite structure consisting of an inner foamed resin insulation layer 4 and an outer non-foamed resin coating 5.
[0065] The internal foamed resin insulation layer 4 has good thermal insulation performance, which can effectively reduce the heat transfer between the pipe body 1 and the external environment, reduce heat loss or absorption, thereby maintaining the relative stability of the pipe temperature, playing a heat preservation role, and meeting the pipeline's temperature control requirements.
[0066] The external non-foamed resin coating 5 can provide a certain mechanical strength and wear resistance, protecting the internal foamed resin insulation layer 4 from damage by external physical factors, such as scratches and collisions. It can also prevent the insulation layer from being corroded by chemical substances, extending the service life of the entire assembled protective cover 2.
[0067] Example 5:
[0068] This embodiment provides a pipe insulation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0069] The heat insulation sleeve 30 includes:
[0070] A temperature control layer 300 is wrapped around the tube body 1, and a fluid channel 301 for temperature-controlled fluid to pass through is provided inside the temperature control layer 300;
[0071] A vacuum insulation layer 302 is wrapped around the temperature control unit, and a vacuum chamber 303 is provided inside the vacuum insulation layer 302 after vacuuming and sealing.
[0072] Both the inlet pipe 31 and the outlet pipe 32 are connected to the fluid channel 301.
[0073] A temperature control layer 300 surrounds the outside of the pipe body 1 and has an internal fluid channel 301 for the passage of temperature-controlled fluid. Through heat exchange between the temperature-controlled fluid and the pipe body 1, the temperature of the pipe body 1 is regulated and maintained within the desired range. The temperature control layer 300 is a structure that fits tightly against the pipe body 1. Its internal fluid channel 301 can be designed in various shapes, such as spiral or serpentine, to increase the contact area and heat exchange time between the temperature-controlled fluid and the pipe body 1. The temperature control layer 300 fits tightly against the pipe body 1 and is connected to the inlet pipe 31 and the outlet pipe 32, ensuring smooth inflow and outflow of the temperature-controlled fluid.
[0074] The vacuum insulation layer 302 surrounds the temperature control layer 300. The internal vacuum chamber 303 effectively reduces heat conduction and convection, further enhancing the insulation effect and reducing heat loss. The vacuum insulation layer 302 is a sealed structure surrounding the temperature control layer 300, forming a relatively independent vacuum space. The vacuum insulation layer 302 is tightly bonded to the temperature control layer 300, and the vacuum level of the vacuum chamber 303 is ensured through a sealing process.
[0075] Example 6:
[0076] This embodiment provides a pipe insulation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0077] The fluid channel 301 of the temperature control unit is provided with a number of slow-flow protrusions 6 for extending the heat exchange time between the temperature control fluid and the tube 1.
[0078] The flow-slowing protrusions 6 are disposed within the fluid channel 301 of the temperature control layer 300. Their main function is to prolong the heat exchange time between the temperature-controlled fluid and the tube body 1. When the temperature-controlled fluid flows through the flow-slowing protrusions 6, it changes its flow direction and velocity, increasing the contact time with the tube body 1, thereby improving heat exchange efficiency. The flow-slowing protrusions 6 are generally raised structures, and their shapes can be columnar, spherical, or sheet-like, etc., and they are evenly distributed within the fluid channel 301 to ensure that the temperature-controlled fluid is subjected to a flow-slowing effect throughout the entire channel. The flow-slowing protrusions 6 are integrally formed with the temperature control layer 300 or fixed within the fluid channel 301 by welding, bonding, or other methods.
[0079] Example 7:
[0080] This embodiment provides a pipe insulation device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0081] The magnetic attraction component 33 includes:
[0082] The first magnetic suction plate 330 is located at the end of the heat insulation sleeve 30;
[0083] The second magnetic plate 331 attracts the first magnetic plate 330. The second magnetic plate 331 is located on the end of the adjacent heat insulation sleeve 30 opposite to the first magnetic plate 330.
[0084] The first magnetic plate 330, as part of the magnetic assembly 33, primarily functions to generate a magnetic attraction with the second magnetic plate 331, thereby connecting two adjacent heat insulation sleeves 30 together. This ensures the integrity and stability of the heat insulation sleeve, achieving a good heat insulation effect. The first magnetic plate 330 typically consists of a magnetic material layer and a mounting layer. The magnetic material layer is the core component generating the magnetic force, while the mounting layer is used to fix the magnetic plate to the heat insulation sleeve 30. The first magnetic plate 330 is generally a rectangular or circular thin plate. This shape increases the contact area with the second magnetic plate 331, thereby enhancing the magnetic connection effect and facilitating installation at the end of the heat insulation sleeve 30. The first magnetic plate 330 is installed at one end of the heat insulation sleeve 30, typically in a specific mounting groove on the outer surface or inside the end of the heat insulation sleeve 30, to correspond with the second magnetic plate 331 on the adjacent heat insulation sleeve 30. The first magnetic plate 330 can be fixed together with the heat insulation sleeve 30 by means of adhesive, bolt connection or snap-fit, etc.
[0085] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
