Description

Technical Field

[0001] This utility model relates to a pipe, specifically, to a spliced ​​outdoor antifreeze pipe. Background Technology

[0002] In low-temperature environments, ordinary metal or plastic pipes, lacking effective insulation, are prone to freezing of their internal media (such as water or oil) due to heat dissipation, leading to blockages or even ruptures and affecting fluid transport. Existing pipe antifreeze methods mainly fall into two categories: one is wrapping the pipe with insulation layers such as cotton, linen, or foam, but this method is not very effective in extreme low temperatures; the other is installing cable or steam tracing on the outside of the pipe, but this method consumes a lot of energy and it is not easy to find power or steam sources in the field.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a scientifically designed, heat-tracing, low-energy-consumption, highly effective, and practical spliced ​​outdoor antifreeze pipe.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a spliced ​​outdoor antifreeze pipe, comprising a delivery pipe, an outer sleeve fitted over the delivery pipe, and an electric heating assembly. The delivery pipe has corresponding socket interfaces at both ends. The inner walls of both ends of the outer sleeve are sealed to the outer walls of both ends of the delivery pipe via sealing plates. The outer sleeve, the delivery pipe, and the two sealing plates form a heat storage cavity, which is filled with a phase change energy storage material. The electric heating assembly passes through the heat storage cavity, and its terminals extend from both ends of the heat storage cavity. The outer sleeve has wiring space corresponding to the terminals of the electric heating assembly to provide electric heating for the phase change energy storage material and the fluid in the delivery pipe.

[0006] Beneficial effects: By setting socket interfaces at both ends of the conveying pipe, pipes of different lengths can be spliced ​​according to site requirements, facilitating mass production and field construction; the heat storage chamber is set between the conveying pipe and the outer casing, and the phase change energy storage material is filled in the heat storage chamber; after the electric heating component is connected to the power supply, it can heat the liquid in the pipe. When the temperature is high, the phase change energy storage material can absorb excess heat and turn into liquid, reducing heat loss. When the temperature of the liquid in the pipe is low, the phase change energy storage material can turn back into solid, releasing heat and playing an auxiliary heating role, thereby reducing the energy consumption of the electric heating component.

[0007] Based on the above, the electric heating assembly includes two main wires connected together and several electric heating branch wires spaced apart. The two main wires are arranged axially through the heat storage chamber, and each end of the two main wires is provided with corresponding terminals. Each electric heating branch wire is wound in a ring around the outer wall of the delivery pipe and its two ends are respectively connected to the two main wires.

[0008] Beneficial effects: The terminal block design facilitates the connection of the main wires in series or to the power supply. The two main wires are used to connect the positive and negative poles respectively. Several heating branches are connected in parallel to the two main wires. After the power is turned on, the heating is generated, which not only increases the contact area and speeds up the heating, but also makes the heating more uniform.

[0009] Based on the above, the phase change energy storage material is paraffin wax.

[0010] Based on the above, it also includes a photovoltaic panel and a battery, wherein the photovoltaic panel charges the battery and the battery supplies power to the electric heating component.

[0011] Beneficial effects: Utilizing solar energy for power generation solves the problems of difficulty in finding power sources in the wild and environmental protection.

[0012] Based on the above, the outer wall of the outer sleeve is wrapped with an insulation layer.

[0013] Beneficial effects: The insulation layer can reduce the loss of heat from the phase change energy storage material to the outside cold air, further reducing energy consumption. Attached Figure Description

[0019] The technical solution of this utility model will be further described in detail below through specific embodiments. Example 1

[0020] like Figure 1 and Figure 2 As shown, a spliced ​​outdoor antifreeze pipe includes a delivery pipe 1, an outer sleeve 2 sleeved on the outside of the delivery pipe 1, and an electric heating assembly. The two ends of the delivery pipe 1 are provided with corresponding socket interfaces, which are composed of a socket 11 and a spigot 12 for pipe splicing. The inner walls of the two ends of the outer sleeve 2 are respectively sealed to the outer walls of the two ends of the delivery pipe 1 through sealing plates 4. The outer sleeve 3, the delivery pipe 2, and the two sealing plates 4 form a heat storage cavity 5, which is filled with a phase change energy storage material. In this embodiment, the phase change energy storage material is paraffin wax (not shown in the figure).

[0021] The electric heating assembly specifically includes two main wires 3 connected together and several electric heating branch wires 9 spaced apart. The two main wires 3 are arranged axially through the heat storage chamber 5, and their two ends exit from both ends of the heat storage chamber 5. Specifically, they can exit from the two sealing plates 4, or from both ends of the outer tube 3, or one end can exit from the sealing plate 4 and the other end from one end of the outer tube 3. The electric heating branch wires 9 are made of high-resistance alloy materials (such as nickel-chromium alloy, copper-nickel alloy, carbon fiber), and the outer layer is covered with insulating material (such as silicone, PVC, Teflon). Heat is generated when current passes through them. Each electric heating branch wire 9 is wound in a ring around the outer wall of the conveying pipe 1, and its two ends are respectively connected to the two main wires 31 to form a parallel connection. This can increase the contact area, accelerate the heating speed, and make the heating more uniform.

[0022] To facilitate wiring, the two main wires 3 are provided with corresponding terminals 31 at both ends. The outer sleeve 2 is provided with wiring space at both ends of the electric heating component 3. For example, the outer sleeve 2 can be shorter to open up the space outside the socket 11, so as to facilitate the connection between the main wires 3 or the connection between the main wires 3 and the power cord.

[0023] Working principle:

[0024] By setting socket interfaces at both ends of the conveying pipe 1, pipes of different lengths can be spliced ​​together according to site requirements. Specifically, the spliced ​​outdoor antifreeze pipe can be set to a fixed specification of 1m, 2m or 3m, which is convenient for mass production and field construction. The conveying pipe 1 is used to transport water. When the weather is cold, the electric heating component can heat the liquid in the pipe after being connected to the power supply. When the temperature is high, the phase change energy storage material can absorb the excess heat and turn into liquid, reducing heat loss. When the temperature of the liquid in the pipe is low, the phase change energy storage material can turn back into solid and release the heat, playing an auxiliary heating role, thereby reducing the energy consumption of the electric heating component.

[0025] To further reduce energy consumption, the outer wall of the outer jacket 2 is wrapped with an insulation layer 6, which can be made of cotton, linen or foam, thus reducing the loss of heat from the phase change energy storage material to the outside cold air. Example 2

[0026] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the spliced ​​outdoor antifreeze pipe also includes a photovoltaic panel 7 and a storage battery 8. The photovoltaic panel 7 charges the storage battery 8, and the storage battery 8 supplies power to the electric heating component. In this embodiment, the photovoltaic panel 7 and the pipe are separated from each other, and one photovoltaic panel 7 supplies power to multiple sections of the pipe, which solves the problems of inconvenience in finding power sources in the wild and environmental protection. Example 3

[0027] like Figure 4 As shown, the difference between this embodiment and embodiment 2 is that a small-sized photovoltaic panel 7 is used. The photovoltaic panel 7 is installed on the pipe through a support, and each photovoltaic panel 7 only supplies power to the electric heating component on this section of the pipe.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
