Description

Technical Field

[0001] This invention relates to the field of building water supply and drainage pipe technology, and more specifically, to a self-heating anti-icing composite water pipe. Background Technology

[0002] In cold regions, where winter temperatures remain below freezing for extended periods, PVC (polyvinyl chloride) water pipes used for water transport outdoors or in uninsulated spaces face a severe risk of freezing. Once PVC pipes freeze, several problems arise: First, the expansion of frozen water can crack the pipes, causing leaks that disrupt water supply and potentially damage surrounding buildings, facilities, and equipment, leading to economic losses. Second, after the pipes thaw, damage to the inner walls can affect water quality, causing inconvenience and health risks for users.

[0003] Currently, conventional techniques for preventing PVC water pipes from freezing mainly fall into two categories: The first is passive insulation, which involves wrapping the outer wall of the pipe with insulation materials such as rock wool, glass wool, or polyurethane foam sleeves. While this method can delay heat loss to some extent, its insulation effect is limited in prolonged extremely cold weather. It cannot actively replenish heat, ultimately making it difficult to prevent the pipes from freezing. Furthermore, insulation materials are prone to absorbing water and failing in humid environments, and their fire resistance varies, posing certain safety hazards. The second category is active external heating, typically represented by laying electric heating tape. This method involves attaching or wrapping the electric heating tape tightly to the outer wall of the pipe, providing a heat source by applying electricity. However, this method has obvious drawbacks: First, the installation process is complicated, requiring additional fixing, and the fit between the electric heating cable and the water pipe wall is difficult to guarantee, which can easily lead to uneven heating and local overheating or cold spots; Second, the electric heating cable itself requires an additional protective layer, resulting in low system integration, large space occupation, and poor aesthetics; Third, the traditional electric heating cable control system is relatively simple, with weak precise temperature control capabilities, which may lead to energy waste.

[0004] Therefore, there is an urgent market demand and significant practical value in developing an integrated PVC water pipe that combines efficient, uniform, and self-controlled heating functions with good heat preservation and fire resistance. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a self-heating anti-icing composite water pipe, which aims to solve the problems existing in the prior art.

[0006] According to the present invention, a self-heating, anti-icing composite water pipe is provided, comprising a water pipe body and an intelligent temperature control device disposed on the water pipe body; wherein, The water pipe body comprises, from the inside out, an inner pipe, a heating layer, a heat insulation layer, a fire-retardant layer, and an outer protective layer, arranged sequentially; the heating layer is made of a conductive polymer composite material and is used to generate Joule heat when energized.

[0015] Preferably, the intelligent temperature control device integrates a wireless communication module for remote monitoring and control.

[0016] The self-heating anti-icing composite water pipe provided by this invention can directly heat the water inside the pipe by setting a heating layer on the outside of the inner pipe, effectively preventing the water from freezing. The heating layer is made of conductive polymer material, ensuring uniform heat distribution. The intelligent temperature control device can monitor the temperature of the inner pipe in real time and automatically control the power supply and disconnection of the heating layer to achieve "on-demand heating." Combined with the insulation layer, energy consumption is reduced.

[0024] Various embodiments of the invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0025] This invention provides a self-heating, anti-icing composite water pipe, see [link / reference]. Figure 1 and Figure 2 The self-heating, anti-icing composite water pipe includes a pipe body 1 and an intelligent temperature control device 2 mounted on the pipe body 1. The pipe body 1 comprises, from the inside out, an inner pipe 11, a heating layer 12, an insulation layer 13, a fire-retardant layer 14, and an outer protective layer 15, arranged sequentially. The heating layer 12 is made of conductive polymer composite material and generates Joule heat when energized. The intelligent temperature control device 2 includes a temperature sensor 21 and an intelligent controller 22. The temperature sensor 21 is located between the inner pipe 11 and the heating layer 12 and is used to detect the temperature at the inner pipe 11. The intelligent controller 22 is connected to the temperature sensor 21 and the heating layer 12 and automatically controls the energization or de-energization of the heating layer 12 based on the detected temperature at the inner pipe 11. This self-heating, anti-icing composite water pipe can achieve self-heating through the heating layer 12, effectively preventing the water pipe from freezing in low-temperature environments and ensuring normal use.

[0026] The inner pipe 11 is made of PVC material, which has good corrosion resistance and water resistance, ensuring normal water delivery. The inner diameter of the inner pipe 11 is determined according to actual usage requirements, with common specifications including DN150-DN200. The wall thickness of the inner pipe 11 is designed based on the working pressure of the water pipe and the usage environment. Preferably, the wall thickness of the inner pipe 11 is 2-5mm to ensure sufficient strength and durability. In this embodiment, the wall thickness of the inner pipe 11 is 3mm.

[0027] Specifically, during the fabrication of the inner tube 11, suitable PVC raw materials are selected according to the required water pipe specifications, and the inner tube 11 is manufactured through an extrusion molding process. During the extrusion process, parameters such as temperature, pressure, and extrusion speed are strictly controlled to ensure that the inner tube 11 has a uniform wall thickness and that its inner diameter meets design requirements. For example, for a DN50 water pipe, the extrusion temperature is set to 180-200℃, the pressure to 5-8MPa, and the extrusion speed to 1-2m / min, resulting in an inner tube 11 with a wall thickness of 3mm.

[0028] The heating layer 12 is disposed on the outside of the inner tube 11, tightly wrapping the inner tube 11. The heating layer 12 is made of a conductive polymer composite material. This conductive polymer composite material can generate heat when electricity is applied. Specifically, the conductive polymer composite material includes a polymer matrix and conductive fillers dispersed therein. The conductive fillers form conductive pathways in the polymer matrix, generating heat when current passes through. It has self-limiting temperature characteristics; the resistance increases as the temperature rises, limiting the current and heat generation. It has good flexibility and processability, and can be made into coatings of various colors and shapes. It has good insulation properties and is safe to use. This conductive polymer composite material can be used for local heating and heat preservation of electronic devices, such as battery heating in mobile phones and computers; it can also be used in building insulation, pipe antifreeze, and other fields. Preferably, the thickness of the heating layer 12 is 1-3mm. In this embodiment, the designed thickness of the heating layer 12 is 2mm. Electrodes are provided at both ends of the heating layer 12, which are connected to a power source through wires. The power source can be a stable DC power supply provided by transforming and rectifying mains electricity. The voltage is generally within a safe voltage range, such as 12V-36V, to ensure safe use. Specifically, heating is achieved by connecting a safe low-voltage DC power supply of 12V, 24V, or 36V to both ends of the heating layer 12, utilizing its conductivity to generate Joule heating. An insulated wire is provided between the heating layer 12 and the insulation layer 13 to connect the two ends of the heating layer 12 to the power supply.

[0029] Specifically, during the preparation of the heating layer 12, conductive particles are mixed with polymer materials in a certain proportion, and a conductive polymer composite material is produced through processes such as stirring and kneading. The prepared conductive polymer composite material is then uniformly coated or extruded onto the outer side of the inner tube 11 to form the heating layer 12. Electrodes are installed at both ends of the heating layer 12, and wires are led out from them. Figure 3 As shown, in this embodiment, the metal electrode 204 is fixedly connected to the electrode base 203 and connected to the heating layer 12. The electrode base 203 extends out of the water pipe body 1. The wire is connected to the electrode base 203 and electrically connected to the metal electrode 204. The other end of the wire is connected to an external 12-36V low-voltage DC power supply.

[0030] The insulation layer 13, located outside the heating layer 12, is made of polyurethane foam. Polyurethane foam has excellent insulation properties and extremely low thermal conductivity, effectively reducing heat loss from the heating layer 12 and improving heating efficiency. The thermal conductivity of the polyurethane foam ranges from 0.02 to 0.03 W / (m·K). The thickness of the insulation layer 13 is determined based on the actual operating environment and insulation requirements; preferably, the thickness is 7-15 mm. In this embodiment, the designed thickness of the insulation layer 13 is 10 mm. The insulation layer 13 is tightly wrapped around the heating layer 12 through on-site foaming, ensuring a seamless connection and achieving good insulation performance.

[0031] Specifically, during the construction of the insulation layer 13, the raw materials of polyurethane foam are mixed in a certain proportion, and the mixed raw materials are injected into the inner tube 11, which encloses the heating layer 12, through foaming equipment for on-site foaming. During the foaming process, the foaming time and temperature are controlled to ensure that the polyurethane foam is evenly wrapped around the heating layer 12, forming the insulation layer 13.

[0032] The fire-retardant layer 14 is made of inorganic intumescent fire-retardant material. Specifically, an inorganic intumescent fire-retardant coating is applied to the outside of the insulation layer 13. This fire-retardant coating has good stability at room temperature. When exposed to high temperatures or open flames, the coating expands rapidly, forming a dense foam insulation layer that effectively prevents heat transfer and flame spread. The thickness of the fire-retardant material layer depends on the fire rating requirements. Preferably, the thickness of the fire-retardant layer 14 is 1-3 mm. In this embodiment, the designed wall thickness of the fire-retardant layer 14 is 2 mm. The fire-retardant layer 14 undergoes special processing to ensure a tight bond with both the insulation layer 13 and the outer protective layer 15 without affecting the overall structural performance.

[0033] Specifically, during the application of the fire-retardant layer 14, first, according to the instructions for the inorganic intumescent fire-retardant coating, mix the components in the specified proportions and stir thoroughly to ensure uniformity and absence of lumps. Application can be done by spraying or brushing to form a coating of a certain thickness. After application, place the water pipe in a well-ventilated environment at 20-30℃ for 24-48 hours to allow it to dry and cure completely.

[0034] The outer protective layer 15 is made of HDPE material. As the outermost structure, the outer protective layer 15 is made of high-density polyethylene (HDPE) material. The density of HDPE material is 0.941-0.965 g / cm³. 3 HDPE material possesses excellent wear resistance, weather resistance, and mechanical strength, effectively protecting the internal heating layer 12 and insulation layer 13 from external environmental damage, such as ultraviolet radiation and mechanical impact. Preferably, the thickness of the outer protective layer 15 is 2-5 mm. In this embodiment, the designed wall thickness of the outer protective layer 15 is 3 mm. In specific implementation, the outer protective layer 15 can be tightly bonded to the fire-retardant layer 14 through co-extrusion or other effective processes. The surface of the outer protective layer 15 can be treated with an anti-slip coating to increase the stability of the water pipe during installation and use.

[0035] Specifically, during the molding and construction of the outer protective layer 15, a suitable HDPE raw material is selected and extruded to form the outer protective layer 15. The outer protective layer 15 is then fitted over the fire-retardant layer 14 and bonded tightly to it using hot-melt or adhesive methods. For example, HDPE granules are extruded at a temperature of 220-240℃ to form an outer protective layer 15 with a thickness of 3mm, which is then bonded to the fire-retardant layer 14 using a hot-melt process.

[0036] The intelligent temperature control device 2 includes a temperature sensor 21 and an intelligent controller 22, enabling precise control of the heating process. The temperature sensor 21 is installed between the inner pipe 11 and the heating layer 12, and can monitor the water temperature inside the inner pipe 11 in real time. The intelligent controller 22, based on a microcontroller, automatically controls the power supply to or off of the heating layer 12 according to the temperature detected by the temperature sensor 21. When the temperature sensor 21 detects that the water temperature inside the inner pipe 11 is lower than a set threshold (e.g., 5°C), the intelligent controller 22 automatically turns on the power to the heating layer 12, causing it to start working. When the water temperature rises to a set upper limit (e.g., 10°C), the intelligent controller 22 automatically cuts off the power to the heating layer 12, stopping heating. This allows for automatic adjustment of the heating process based on the actual water temperature, achieving energy saving and precise control. Preferably, the intelligent temperature control device 2 integrates a wireless communication module for remote monitoring and control, allowing users to manage the water pipe status anytime, anywhere, thus improving the user experience.

[0037] In practical implementation, the temperature sensor 21 can be installed at a suitable position between the inner pipe 11 and the heating layer 12 to ensure that it can accurately detect the temperature of the water inside the inner pipe 11; the intelligent controller 22 can be installed in a location that is easy to operate and maintain, such as near the valve of the water pipe or in a dedicated control box. Figure 3 As shown, in another embodiment, a heating temperature control device can also be used connected to the water pipe body 1. The heating temperature control device includes an electrode base 203, a metal electrode 204, a bimetallic thermostat 202, and a bimetallic thermostat probe 201. The metal electrode 204 is disposed on the electrode base 203, which is disposed on the water pipe body 1. The metal electrode 204 is connected to the heating layer 12 and is electrically connected to an external low-voltage DC power supply through a wire. The bimetallic thermostat 202 is connected to the power supply circuit of the heating layer 12. The end of the bimetallic thermostat probe 201 is disposed on the outer surface of the inner tube 11 to detect the temperature at the inner tube 11. The bimetallic thermostat 202 can automatically turn on or off the power supply of the heating layer 12 according to the temperature change at the surface of the inner tube 11.

[0038] Furthermore, the self-heating anti-icing composite water pipe also includes a connecting device 3, which is disposed on the water pipe body 1 and used to connect the ends of two adjacent sections of the water pipe body 1, and to maintain an electrical connection between the heating layers 12 of the two adjacent sections of the water pipe body 1. See also Figure 4 and Figure 5 The connecting device 3 includes: a flange 31, a conductive adhesive layer 32, and a sealing gasket (not shown in the figure); wherein, the flange 31 is made of engineering plastic and is fixed to the end of the water pipe body 1; the conductive adhesive layer 32 is coated on the mating surface of the flange 31 to realize the electrical connection between the heating layers 12 of two adjacent sections of the water pipe body 1; the sealing gasket is made of elastic rubber material and is disposed on the mating surface of the flange 31 to realize the sealing at the connection of the flange 31 of the two connected sections of the water pipe body 1.

[0039] Specifically, flange 31 is made of engineering plastic (PVC), which has advantages such as light weight and low cost. Flange 31 has bolt holes for fastening the flanges 31 of two water pipes together with flange bolts 311. When connecting flanges 31, they are first heat-fused to the water pipe body 1. A conductive adhesive layer 32 is coated on the contact surface of flange 31. This conductive adhesive layer 32 contains conductive material (carbon conductive adhesive) and has a low volume resistivity (≤1×10⁻⁶). -3 It has a high shear strength (≥10MPa) and a high shear strength (Ω·cm). It not only enables conductive connections between the heating layers 12 but also enhances the adhesion between the flanges 31, improving connection reliability. A sealing gasket, made of rubber (such as silicone rubber or EPDM rubber), is placed between the two flanges 31. These rubber materials have good elasticity and sealing performance, a thickness of 1-3mm, and a compression set ≤15%. The sealing gasket effectively prevents liquid leakage from the water pipes, ensuring the normal operation of the water pipe system.

[0040] The operation steps for connecting two adjacent sections of the water pipe body 1 using the connecting device 3 are as follows: Pipe preparation: Use sandpaper to sand the connection ends of the two water pipe bodies 1 (heating layer 12) to remove the oxide layer and stains, exposing the conductive polymer material layer. Then wipe with a cleaning agent to ensure the surface is clean and dry, laying the foundation for subsequent operations.

[0041] Install flange 31: Place the matching flange 31 on the two water pipe bodies 1 respectively, so that the sealing surface is in contact with the outer surface of the water pipe body 1, and place a water-resistant and heat-resistant rubber sealing gasket in the middle.

[0042] Apply adhesive: Thoroughly mix the conductive adhesive and apply it evenly to the connection end of the heating layer 12 of one tube using a brush or dropper. The thickness should be controlled at 0.2-0.5mm to ensure uniform distribution of conductive particles.

[0043] Pipe connection: Quickly and accurately connect the connecting end of the other water pipe body 1 to the glued end, apply pressure and hold for a while to make the heating layer 12 fit tightly, expel air from the gaps, and at the same time ensure that the axis of the water pipe body 1 is aligned.

[0044] Adhesive curing: Follow the adhesive instructions and allow it to cure at a suitable temperature and humidity. Avoid external forces or vibrations during the curing process to ensure optimal curing results.

[0045] Fasten flange 31: Pass flange bolts 311 through the bolt holes and install nuts, tighten them gradually in a diagonal sequence, control the torque, so that the flange is evenly stressed, and ensure that the sealing gasket is compressed in place to achieve a good seal and a firm connection.

[0046] The self-heating, anti-icing composite water pipe provided by this invention has the following beneficial effects: Highly efficient anti-icing: By setting a heating layer inside the water pipe body, the water inside the inner pipe can be heated directly, effectively preventing the water from freezing. Compared with traditional insulation methods, the anti-icing effect is more reliable, ensuring the normal operation of the water pipe even in extremely cold weather.

[0047] Uniform heating: The heating layer made of conductive polymer composite material can achieve uniform heating, avoiding local overheating or undercooling, ensuring the consistency of water temperature throughout the water pipe, and improving heating efficiency and effect.

[0048] Energy-saving and intelligent: The combined use of temperature sensors and intelligent controllers enables automatic adjustment of the heating process based on water temperature, avoiding unnecessary energy consumption and achieving energy savings. Simultaneously, wireless communication capabilities allow for remote monitoring and control, enabling users to manage water pipe status anytime, anywhere, thus enhancing the user experience.

[0049] Compact and durable: The integrated design of the inner pipe, heating layer, insulation layer, fire-retardant layer, and outer protective layer makes the water pipe structure compact and easy to install. The materials selected for each layer are carefully chosen, possessing excellent corrosion resistance, weather resistance, fire retardancy, and mechanical strength, enabling it to adapt to various harsh outdoor environments and extending the service life of the water pipe.
