[0025] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] Please refer to Figures 1 to 5 The utility model provides a pipeline protection device, including a first arc-shaped protective plate 1, a second arc-shaped protective plate 2, an elastic support assembly 3, a fixing assembly 4 and a protective canvas 5, wherein both ends of the first arc-shaped protective plate 1 are fixedly mounted on the second arc-shaped protective plate 2, the elastic support assembly 3 is fixedly mounted on the inner wall of the first arc-shaped protective plate 1, the elastic support assembly 3 is fixedly mounted on the inner wall of the second arc-shaped protective plate 2, the rolling end of the elastic support assembly 3 is pressed on the outer surface of the pipeline, the elastic support assembly 3 enables the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 to be displaced along the length direction of the pipeline, the fixing assembly 4 is fixedly mounted on the outer wall of the first arc-shaped protective plate 1, the fixing assembly 4 is fixedly mounted on the outer wall of the second arc-shaped protective plate 2, the fixing assembly 4 is used to fix the protective canvas 5, both ends of the protective canvas 5 are mounted on the fixing assembly 4, and the protective canvas 5 is used to shade and keep out the cold.

[0027] Specifically, the first arc-shaped protective plate 1 is fixedly provided with a first mounting plate 1.1 at both ends, and a first threaded hole 1.2 is provided on the outer surface of the first mounting plate 1.1; the second arc-shaped protective plate 2 is fixedly provided with a second mounting plate 2.1 at both ends, and a second threaded hole 2.2 is provided on the outer surface of the second mounting plate 2.1; it also includes a bolt 6, both ends of the bolt 6 are threadedly connected to the first threaded hole 1.2 of the first mounting plate 1.1, and both ends of the bolt 6 are threadedly connected to the second threaded hole 2.2 of the second mounting plate 2.1, and the bolt 6 is used to threadably connect the two ends of the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 to fix the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 together.

[0028] Furthermore, the bolt 6 passes through the first mounting plate 1.1 and the first threaded hole 1.2 of the first arc-shaped protective plate 1 and the second mounting plate 2.1 and the second threaded hole 2.2 of the second arc-shaped protective plate 2 to threadably fix the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 together, and one of the first arc-shaped protective plate 1 or the second arc-shaped protective plate 2 is passed through the bottom of the pipeline to dock with the first arc-shaped protective plate 1 or the second arc-shaped protective plate 2 above the pipeline. The elastic support assembly 3 is continuously fixed by the bolt 6 to compress the elastic support assembly 3, and the rolling end of the elastic support assembly 3 is attached to the outer wall of the pipeline. The first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 can be displaced along the length direction of the pipeline through the elastic support assembly 3. The fixing assembly 4 is used to fix the protective canvas 5, so that the protective canvas 5 protects the pipeline to prevent the pipeline on the ground surface from being directly exposed to the sun, resulting in temperature increase. The principle of thermal expansion and contraction makes the fluid temperature inside the pipeline too high, which will cause significant thermal expansion of the pipeline. If there is no sufficient expansion compensation device or expansion room, the pipeline may be deformed or ruptured due to excessive stretching or compression, thereby reducing the sealing effect.

[0029] The utility model can be displaced along the length direction of the pipeline, has the function of adjusting the protection length distance, and is convenient for recovering the shielding protection canvas 5, and is easy to install and disassemble.

[0030] More specifically, the elastic support assembly 3 includes an elastic spring 3.1, a mounting seat 3.2, a wheel frame 3.3 and a roller 3.4, wherein the top of the elastic spring 3.1 is fixedly mounted on the inner wall of the first arc-shaped protective plate 1, and the top of the elastic spring 3.1 is fixedly mounted on the inner wall of the second arc-shaped protective plate 2. The elastic spring 3.1 enables the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 to connect pipes of different types. The bottom of the elastic spring 3.1 is fixedly mounted on the top of the mounting seat 3.2, the top of the wheel frame 3.3 is fixedly mounted on the bottom of the mounting seat 3.2, and the roller 3.4 is rotatably mounted in the wheel frame 3.3. The roller 3.4 can be displaced along the length direction of the pipe to facilitate adjustment of the interval distance.

[0031] Two elastic springs 3.1 are arranged in the same group of elastic support components 3, and the two elastic springs 3.1 are arranged symmetrically, which facilitates maintaining balance. Six rollers 3.4 are arranged in the same group of elastic support components 3, and each of the six rollers 3.4 is a group of three. The two groups of rollers 3.4 are arranged symmetrically, which facilitates the rollers 3.4 to stick to the outer surface of the pipe.

[0032] More specifically, the fixing assembly 4 includes a threaded column 4.1 and a threaded cap 4.2. The bottom of the threaded column 4.1 is fixedly mounted on the outer walls of the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2. The threaded column 4.1 is connected to the outer surfaces of the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 by welding, and the threaded cap 4.2 is threadedly mounted on the bottom of the threaded column 4.1.

[0033] Both ends of the protective canvas 5 are provided with mounting holes 5.1, and the protective canvas 5 is sleeved on the threaded column 4.1 through the mounting holes 5.1.

[0034] More specifically, by respectively attaching the first arc-shaped protective plate 1 or the second arc-shaped protective plate 2 to the outer surface of the pipe, the roller 3.4 of the elastic support assembly 3 of the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 is attached to the outer surface of the pipe, and the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 are threadedly connected together through the first threaded hole 1.2 of the first arc-shaped protective plate 1 and the second threaded hole 2.2 of the second arc-shaped protective plate 2 by the bolt 6. When the bolt 6 connects the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2, the elastic spring 3.1 in the elastic support assembly 3 is compressed, so that the roller 3.4 is more closely attached to the outer surface of the pipe.

[0035] By pushing the first arc-shaped protective plate 1 or the second arc-shaped protective plate 2, the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2 are displaced back and forth on the outer surface of the pipeline through the rollers 3.4 in the elastic support assembly 3, so that the position of the utility model on the pipeline can be adjusted.

[0036] The protective canvas 5 is fastened by the fixing components 4 on the first arc-shaped protective plate 1 and the second arc-shaped protective plate 2, the threaded cap 4.2 of the fixing component 4 is removed from the threaded column 4.1, and then the protective canvas 5 is put on the threaded column 4.1 through the mounting hole 5.1, and then the threaded cap 4.2 is screwed on to fix the protective canvas 5. The pulled-up protective canvas 5 is covered on the pipeline to protect the pipeline and avoid possible creep of the pipeline material under high temperature, that is, the material slowly extends over time under constant stress. Long-term accumulation will lead to loss of pipeline strength and plastic deformation, resulting in poor sealing performance, causing fluid to flow out of the pipeline, or affecting the fluid in the pipeline to cause temperature rise. For some sensitive fluids such as certain chemicals, medicines or refrigerants, abnormal temperature changes may affect their properties, such as accelerating reactions, reducing activity or changing viscosity, thereby affecting the process and product quality.

[0037] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
