[0003] Chinese patent CN221704813U discloses a prefabricated pipe shell for cold and heat insulation of pipelines. The key technical points are: it includes a transport pipeline, an upper pipe shell, and a lower pipe shell. The upper and lower pipe shells are fixed to the outer side of the transport pipeline. Positioning protrusions are welded to the outer sides of the ends of the upper and lower pipe shells. An annular connector is fixedly pressed onto the surface of the positioning protrusion. A sealing gasket is glued to the inner side of the annular connector. Cold and heat insulation liners are attached to the inner sides of both the upper and lower pipe shells. The cold and heat insulation liners are bonded to the inner walls of the upper and lower pipe shells through a cellulose lining. A mineral wool lining and a rubber-plastic protective plate are fixed to the inner side of the cellulose lining. The transport pipeline is wrapped inside the rubber-plastic protective plate by a sponge pad. This invention solves the problem in the prior art where the prefabricated pipe shell is hardened and shaped to wrap around the outside of the pipeline, making it easy to damage the outer prefabricated pipe shell during pipeline maintenance and affecting the cold and heat insulation effect.

[0030] Reference Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a technical solution: a device for extending the cold insulation time of a cooler pipe, comprising an upper cold insulation shell 1 and a lower cold insulation shell 2. Two first connecting plates 4 and two second connecting plates 5 are fixedly connected to the sides of the upper cold insulation shell 1 and the lower cold insulation shell 2, respectively. The two first connecting plates 4 and the two second connecting plates 5 are symmetrically distributed about the upper cold insulation shell 1. Several connecting bolts 6 are threaded through the inner walls of the two first connecting plates 4 and the two second connecting plates 5. The inner walls of the upper cold insulation shell 1 and the lower cold insulation shell 2 are... A cold-insulating liner 3 is fixedly connected. Two grooves are formed on the lower surfaces of the two second connecting plates 5. Slider blocks 7 are slidably connected to the surfaces of the grooves on all four second connecting plates 5. An "L"-shaped plate 8 is fixedly connected to the lower surface of the slider 7, and the "L"-shaped plate 8 fits tightly against the surface of the second connecting plate 5. A movable plate 9 is fixedly connected to the side of the "L"-shaped plate 8 closest to the first connecting plate 4. Two insertion rods 10 are fixedly connected to the side of the movable plate 9 closest to the first connecting plate 4, and both insertion rods 10 are slidably connected to the inner wall of the first connecting plate 4. The sliders 7 slidably connected to the groove surfaces of the second connecting plates 5 can move, thus ensuring that the movable plate 9 and the insertion rods 10 can move relative to the first connecting plate 4. The insertion rods 10 can be used to connect the first connecting plate 4 and the second connecting plate 5.

[0031] The following is a detailed explanation of its overall setup and function.

[0032] Reference Figures 1-5As shown in this embodiment: A first fixing plate 11 is fixedly connected to the lower surface of each of the two second connecting plates 5. A fixing rod 13 is fixedly connected to the side of the first fixing plate 11 near the "L"-shaped plate 8. A control plate 12 is sleeved on the surface of the fixing rod 13, and the control plate 12 is fixedly connected to the "L"-shaped plate 8. The first fixing plate 11 allows the fixing rod 13 to be installed, thereby guiding the movement of the "L"-shaped plate 8 using the fixing rod 13 and the control plate 12. A first spring 14 is sleeved on the surface of the fixing rod 13, and both ends of the first spring 14 are fixedly connected to the first fixing plate 11 and the control plate 12, respectively. The first spring 14, in conjunction with the fixing plate, restricts the position of the control plate 12.

[0033] Two arc-shaped blocks 18 are installed on the side of each of the two second connecting plates 5 near the control plate 12. The side of the two arc-shaped blocks 18 near the control plate 12 is curved. After the control plate 12 is moved, the position of the control plate 12 can be restricted by the arc-shaped blocks 18, thereby facilitating the installation of the cold insulation device. A second fixing plate 15 is fixedly connected to the side of each of the two second connecting plates 5 near the control plate 12. A slide rod 17 is slidably connected to the inner wall of the second fixing plate 15, and the slide rod 17 is fixedly connected to the arc-shaped blocks 18. The slide rod 17, which is slidably connected to the inner wall of the second fixing plate 15, can move relative to the second connecting plate 5, thereby ensuring the mobility of the arc-shaped blocks 18. A slide plate 16 is fixedly connected to the surface of the slide rod 17. The slide plate 16 is slidably connected to the lower surface of the second connecting plate 5. A guide rod 20 is fixedly connected to the side of the slide plate 16 near the second fixing plate 15, and the guide rod 20 is slidably connected to the inner wall of the fixing plate. The sliding plate 16 and guide rod 20 guide the movement of the sliding rod 17, improving its stability. A second spring 19 is fitted onto the surface of the sliding rod 17, with its two ends fixedly connected to the sliding plate 16 and the second fixed plate 15, respectively. When the sliding plate 16 does not need to be moved, the second spring 19 can restrict its position, and it can also control the sliding plate 16 to return to its original position after it has moved.

[0034] Working principle: When the upper cold insulation shell 1 and the lower cold insulation shell 2 need to be installed on the air cooler pipe, firstly, the moving plate 9 and the insert rod 10 are moved away from the second connecting plate 5. The movement of the moving plate 9 causes the "L"-shaped plate 8 to slide on the surface of the fixed rod 13. At the same time, the slider 7 slides on the sliding groove surface on the second connecting plate 5. When the control plate 12 contacts the arc-shaped block 18, the control plate 12 pushes the arc-shaped block 18 to move closer to the second fixed plate 15. After the control plate 12 moves away from the arc-shaped block 18, under the action of the elastic force of the second spring 19, the sliding plate 16 drives the sliding rod 17 and the guide rod 20 on the second fixed plate 15. The inner wall of plate 5 slides, causing the arc-shaped block 18 to move back to its original position. At this time, the arc-shaped block 18 restricts the position of the control plate 12. Then, the second connecting plate 5 moves closer to the first connecting plate 4, and the arc-shaped block 18 moves away from the control plate 12. Under the action of the spring force of the first spring 14, the control plate 12 moves closer to the first fixed plate 11, and the plug rod 10 moves closer to the first connecting plate 4 and is inserted into the first connecting plate 4. Then, the first connecting plate 4 and the second connecting plate 5 are connected by the connecting bolt 6 to complete the installation of the cold insulation device. Thus, the cold insulation liner 3 can play a role in cold insulation for the air cooler pipe. By using the slider 7, "L"-shaped plate 8, movable plate 9, and insert rod 10, the first connecting plate 4 on the upper cold insulation shell 1 and the second connecting plate 5 on the lower cold insulation shell 2 can be connected during the installation of the pipe insulation device. This restricts the relative position between the upper cold insulation shell 1 and the lower cold insulation shell 2, improving the convenience of installing the connecting bolt 6. By using the second fixed plate 15, sliding rod 17, and arc-shaped block 18, the position of the control plate 12 can be restricted after the "L"-shaped plate 8 is moved, thereby restricting the position of the insert rod 10. This releases the connection between the insert rod 10 and the first connecting plate 4 and the second connecting plate 5, facilitating the disassembly and maintenance of the insulation structure.
