Description

Technical Field

[0001] The utility model relates to the field of pipelines for water supply projects, and particularly relates to an anti-freezing pipeline for water supply projects. Background Technique

[0002] Water conservancy projects are basic livelihood projects. Water diversion pipelines are connected from the water source, and water is introduced into a reservoir through the pipelines for static settlement. Some neutralizing agents are added to neutralize and precipitate the water in the reservoir. Whether it is irrigation water or domestic water, it is necessary to divert the stored water to the place of use through pipelines. Therefore, pipelines are used very frequently. Especially in some residential areas on the Qinghai-Tibet Plateau, there will be a long-term low-temperature environment in winter. In severe cases, the pipelines are prone to icing, which will cause problems for the lives of nearby herdsmen and livestock breeding.

[0003] An anti-freezing pipeline for water conservancy and hydropower projects disclosed in a Chinese utility model (publication number: CN217634516U) includes a pipe body. An installation cavity is provided on the side wall of the pipe body. A plurality of heat conduction pipes are fixedly connected to the inner side wall of the installation cavity. An electric heating wire is fixedly connected to the inner side wall of the heat conduction pipe. One end of the plurality of electric heating wires extending to the outside of the heat conduction pipe is electrically connected to a storage battery. A temperature sensor is electrically connected to the side wall of the storage battery. The pipe body includes a corrosion-resistant layer, an anti-seepage layer, a foaming layer, a heat-insulating layer and a heat-conducting layer. In this utility model, through the mutual cooperation of the heat conduction pipe, the electric heating wire, the storage battery, the temperature sensor, the heat-insulating layer and the heat-conducting layer, the temperature sensor receives the environmental temperature signal. When the temperature is low, it sends a signal to the storage battery for power supply. The storage battery heats the electric heating wire, and the heat is conducted through the heat conduction pipe to heat the pipeline, which can effectively prevent the pipeline from cracking and blocking in cold weather and reduce the maintenance burden of the operators on the pipeline.

[0004] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology. Since the electric heating wire is installed inside the heat conduction pipe, and the heat conduction pipe is fixedly installed inside the installation cavity on the side wall of the pipe body, when the electric heating wire fails due to long-term use or other reasons, it is not convenient to maintain or replace the electric heating wire. Therefore, an anti-freezing pipeline for water supply projects is now proposed. Content of the Utility Model

[0005] In order to improve the problem that the electric heating wire is installed inside the pipe body in the prior art and it is not convenient to maintain or replace the electric heating wire when the electric heating wire fails due to long-term use or other reasons, the present utility model provides an anti-freezing pipeline for water supply projects.

[0031] The following is combined with the attached drawings in the embodiments of the present utility modelFigures 1 - 3 The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1 - 3 Figures 1 - 3 , an anti-freezing pipeline for a water supply project, includes a pipe body 1 and a protection mechanism installed on the surface of the pipe body 1. An anti-corrosion coating 2 is coated on the inner wall of the pipe body 1. The anti-corrosion coating 2 is an epoxy resin composite material coating, which improves the anti-corrosion effect of the inner wall of the pipe body 1. An electric heating tape 3 is arranged between the pipe body 1 and the protection mechanism. The electric heating tape 3 is a prior art, which realizes heating of the pipe body 1, so that the water inside the pipe body 1 is not easily frozen. The electric heating tape 3 is spirally wound around the surface of the pipe body 1, which is beneficial to realizing uniform heating of the pipe body 1. By winding the electric heating tape 3 around the outside of the pipe body 1 to realize heating of the pipe body 1, the inside of the pipe body 1 is not easily frozen. When the electric heating tape 3 fails after long-term use, the electric heating tape 3 is easily separated from the pipe body 1, which is beneficial to the maintenance or replacement of the electric heating tape 3.

[0033] Please refer to Figures 1 - 3 Figures 1 - 3 , the protection mechanism includes an upper semi-circular shell 4, a lower semi-circular shell 5 and a connection component. The upper semi-circular shell 4 and the lower semi-circular shell 5 are combined into a cylindrical shape. The pipe body 1 is located between the upper semi-circular shell 4 and the lower semi-circular shell 5. The upper semi-circular shell 4 and the lower semi-circular shell 5 are connected by a connection component. Through the settings of the upper semi-circular shell 4 and the lower semi-circular shell 5, the protection of the pipe body 1 is realized. Moreover, the electric heating tape 3 is prevented from being directly exposed to the external environment, which is beneficial to the long-term use of the electric heating tape 3. The connection component includes a first connecting plate 6 fixedly installed on both sides of the upper semi-circular shell 4 and a second connecting plate 7 fixedly installed on both sides of the lower semi-circular shell 5. The first connecting plate 6 and the second connecting plate 7 are fixedly connected by a connecting bolt 8. The connection between the upper semi-circular shell 4 and the lower semi-circular shell 5 is realized by means of bolt connection, which is convenient for disassembly and assembly.

[0034] Refer to Figures 1 - 3, heat insulation pads 9 are fixedly connected to the inner walls of the upper semi-circular housing 4 and the lower semi-circular housing 5. The heat insulation pads 9 are connected to the upper semi-circular housing 4 and the lower semi-circular housing 5 by means of bonding. The heat insulation pads 9 are polyurethane heat insulation pads. The setting of the heat insulation pads 9 effectively reduces the influence of the external low-temperature environment on the pipe body 1 and is not likely to cause the heat generated by the electric tracing band 3 to be lost to the external environment. A groove 10 is provided at the bottom of the first connecting plate 6, and a convex strip 11 is fixedly connected to the upper surface of the second connecting plate 7. The convex strip 11 is inserted into the inside of the groove 10. The settings of the groove 10 and the convex strip 11 shield the joint between the first connecting plate 6 and the second connecting plate 7, thereby reducing the heat loss of the pipe body 1 in the heating state. A limiting component for limiting the electric tracing band 3 is fixedly installed on the surface of the pipe body 1. The number of the limiting components is several, and several limiting components are arranged at equal intervals along the length direction of the pipe body 1. The limiting component includes two limiting plates 12 fixedly installed on the surface of the pipe body 1. A limiting groove 13 is formed between the two limiting plates 12, and the electric tracing band 3 is located inside the limiting groove 13. Through the setting of the limiting plates 12, when the electric tracing band 3 is wound around the pipe body 1, it is beneficial to ensure the constancy of the winding pitch of the electric tracing band 3.

[0035] Referring to Figure 3 , a positioning bolt 14 is threadedly connected to one of the limiting plates 12. Through the setting of the positioning bolt 14, by rotating the positioning bolt 14, one end of the positioning bolt 14 abuts against one side of the electric tracing band 3. At this time, in cooperation with the limiting plate 12 on the opposite side, the fixing of the electric tracing band 3 is realized, which is beneficial to the winding of the electric tracing band 3 on the pipe body 1.

[0036] The implementation principle of the present utility model is as follows:

[0037] During construction, the electric tracing band 3 is spirally wound around the surface of the pipe body 1. And when the electric tracing band 3 passes through a limiting groove 13, rotate the positioning bolt 14 so that one end of the positioning bolt 14 abuts against one side of the electric tracing band 3. At this time, in cooperation with the limiting plate 12 on the opposite side, the fixing of the electric tracing band 3 is realized. In this way, after the electric tracing band 3 is installed, the upper semi-circular housing 4 and the lower semi-circular housing 5 with heat insulation pads 9 are surrounded around the surface of the pipe body 1. Since the heat insulation pads 9 are polyurethane heat insulation pads and have a certain compressibility, the limiting components on the pipe body 1 do not affect the installation of the upper semi-circular housing 4 and the lower semi-circular housing 5. Grooves can also be provided at the positions corresponding to the limiting components on the heat insulation pads 9. Finally, the upper semi-circular housing 4 and the lower semi-circular housing 5 are connected by the connecting bolts 8;

[0038] Compared with the prior art, in the present application, an electric tracing band 3 is wound around the outside of the pipe body 1 to heat the pipe body 1, and it is not easy for the inside of the pipe body 1 to freeze. When the electric tracing band 3 fails after long-term use, it is easy to separate the electric tracing band 3 from the pipe body 1, which is beneficial to the maintenance or replacement of the electric tracing band 3. Moreover, through the arrangement of the upper semi-circular shell 4 and the lower semi-circular shell 5, the protection of the pipe body 1 is realized, and the electric tracing band 3 is prevented from being directly exposed to the external environment, which is beneficial to the long-term use of the electric tracing band 3. At the same time, heat preservation pads 9 are fixedly connected to the inner walls of the upper semi-circular shell 4 and the lower semi-circular shell 5, effectively reducing the influence of the external low-temperature environment on the pipe body 1, and it is not easy for the heat generated by the electric tracing band 3 to be lost to the external environment, improving the heating effect of the electric tracing band 3 on the pipe body 1. Further, the first connecting plate 6 and the second connecting plate 7 on the upper semi-circular shell 4 and the lower semi-circular shell 5 are fixedly connected by connecting bolts 8, which is convenient for disassembly and assembly. Immediately afterwards, a groove 10 is opened at the bottom of the first connecting plate 6, and a rib 11 is fixedly connected to the upper surface of the second connecting plate 7. The rib 11 is inserted into the inside of the groove 10. The arrangement of the groove 10 and the rib 11 realizes the shielding of the joint between the first connecting plate 6 and the second connecting plate 7, thereby reducing the heat loss of the pipe body 1 in the heating state.
