[0004] Therefore, it is necessary to propose a corrosion-resistant pipeline compensator for use in hazardous environments to solve the above problems. Utility Model Content

[0007] Preferably, sealing gaskets are fixed to the bottom and top ends of the first transparent semicircular sleeve and the second transparent semicircular sleeve, and the inner sides of the sealing gaskets are attached to the outer sides of the pipe body.
[0008] Preferably, reflective stickers are fixed on the sides of the first transparent semicircular sleeve and the second transparent semicircular sleeve that are away from each other.
[0009] Preferably, both ends of the first transparent semicircular sleeve are fixedly connected with protruding ends, and a snap-in groove is provided on the side where the two protruding ends are close to each other.

[0013] 1. In the actual operation of the utility model, the first transparent semicircular sleeve and the second transparent semicircular sleeve are both made of transparent corrosion-resistant plastic material.

Personnel can determine the leaking location by observing the color of the anhydrous copper sulfate test paper from the outside, which is convenient for personnel to conduct detection.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model provides Figure 1 - Figure 3 The corrosion-resistant pipeline compensator for hazardous environments shown in the figure includes a compensation mechanism and a pipeline body 12. The compensation mechanism includes a first transparent semicircular sleeve 1 and a second transparent semicircular sleeve 2. The first transparent semicircular sleeve 1 and the second transparent semicircular sleeve 2 are snap-connected, and the first transparent semicircular sleeve 1 and the second transparent semicircular sleeve 2 are sleeved on the outside of the pipeline body 12. The first transparent semicircular sleeve 1 and the second transparent semicircular sleeve 2 can be directly snap-connected to the outside of the pipeline body 12 to complete the installation work and protect the outside of the pipeline body 12. Due to the snap-connection, the installation and removal of the first transparent semicircular sleeve 1 and the second transparent semicircular sleeve 2 are relatively simple.
[0021] The specific installation method is that both ends of the first transparent semicircular sleeve 1 are fixedly connected with protruding ends 4, and the sides where the two protruding ends 4 are close to each other are provided with engaging grooves 5. Both ends of the first transparent semicircular sleeve 1 are fixedly connected with protruding blocks 6, and the two protruding blocks 6 are respectively engaged with the corresponding inner parts of the engaging grooves 5. The lengths and widths of the first transparent semicircular sleeve 1 and the second transparent semicircular sleeve 2 are respectively consistent, and the connection can be completed by the matching connection of the protruding blocks 6 and the engaging grooves 5.
[0022] A plurality of semicircular shells 8 are fixed inside the first transparent semicircular sleeve 1 and the second transparent semicircular sleeve 2. Leakage holes are opened on the outer sides of the plurality of semicircular shells 8. The interiors of the plurality of semicircular shells 8 are filled with water-cured materials 9. The arc surfaces of the plurality of semicircular shells 8 are in contact with the outer sides of the pipe body 12. Fixed semicircular disks 10 are connected between the plurality of semicircular shells 8 that correspond vertically to each other. The fixed semicircular disks 10 are attached to the outer sides of the pipe body 12.

When the pipeline body 12 is damaged and the transported water source leaks, the water source will contact the anhydrous copper sulfate test paper 11, causing the anhydrous copper sulfate test paper 11 to change color. People from the outside can determine the leak by observing the color of the anhydrous copper sulfate test paper 11, which is convenient for people to detect.
[0025] Furthermore, when water leaks out, the water will come into contact with the water-solidified material 9 through the leakage hole and the interior of the multiple semicircular shells 8, react with the water-solidified material 9, and become solid, thereby blocking the leakage of the pipeline body 12 and preventing the discharge of water, thereby playing a waterproof role. Since multiple fixed semicircular disks 10 are provided, the leaking area can be isolated and at the same time can play a supporting role, thereby increasing the contact area of the water-solidified material 9 and improving the curing strength.
[0026] It should be noted that the water-curable solidifying material 9 may be made of materials such as gypsum, expanded graphite cement, silicate, etc., and any material that can produce a curing effect when in contact with water may be used.
[0027] Reflective stickers 3 are fixed on the sides of the first transparent semicircular cover 1 and the second transparent semicircular cover 2 that are away from each other, so as to facilitate personnel to detect positions.
