[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a water supply pipe structure for urban pipeline reconstruction, comprising a protective pipe sleeve 1, a water supply pipe 2, a buffer protection device 3 and a connecting device. The water supply pipe 2 is sleeved inside the protective pipe sleeve 1. The buffer protection device 3 for supporting and protecting the water supply pipe 2 is arranged in the gap between the protective pipe sleeve 1 and the water supply pipe 2. The end of the protective pipe sleeve 1 is provided with a connecting device with a telescopic positioning function.

[0023] The buffer protection device 3 includes an inner support ring 31, a support spring bar 32, a support seat 33 and a support ball 34. The inner support ring 31 is sleeved on the inner side of the protective tube sleeve 1, the support spring bar 32 is installed on the inner wall of the inner support ring 31, the support seat 33 is installed on the inner end of the support spring bar 32, and the support ball 34 is movably embedded in the inner arc surface of the support seat 33. The outer side of the water supply pipe 2 is protected by the buffer protection device 3.

[0024] Furthermore, the connecting device includes a regulating sleeve 4, a control socket 5, a support kit 6, a flange 7, an installation screw hole 8, a positioning column 9, a guide cone 10 and a positioning socket 11. A threaded groove is provided on the outer wall of the protective tube sleeve 1 near the end position, and a threaded ring is provided on the inner wall of the regulating sleeve 4. The regulating sleeve 4 is connected to the protective tube sleeve 1 through a threaded connection. The control socket 5 is provided on the outer wall of the regulating sleeve 4, the support kit 6 is installed with the left end of the regulating sleeve 4 through a bearing, the flange 7 is installed with the left end of the support kit 6, the installation screw hole 8 is provided on the surface of the flange 7, the positioning column 9 is installed with the left side wall of the flange 7, and the guide cone 10 is installed with the left end of the positioning column 9. The connecting device can automatically position the connector during docking, which facilitates the docking work.

[0025] Furthermore, there are two flanges 7, which are respectively arranged at the left and right ends of the protective tube sleeve 1. The positioning column 9 and the guide cone 10 are installed on the surface of the flange 7 near the left end, and the positioning hole 11 is opened on the surface of the flange 7 near the right end. The sharp end of the guide cone 10 is inserted into the interior of the positioning hole 11 to align the mounting screw holes 8 of the two flanges 7 to facilitate the installation of the bolts.

[0026] Furthermore, the edge of the inner support ring 31 close to the outer wall is formed into an inclined surface, so that the inner support ring 31 can be easily installed inside the protective sleeve 1 through the inclined surface.

[0027] Furthermore, the diameter of the positioning column 9 is equal to the diameter of the positioning hole 11. After the positioning column 9 is inserted into the positioning hole 11, the two flanges 7 are aligned, so that the mounting screw holes 8 on the surface of the flanges 7 are aligned, making it easier for the bolts to be inserted into the mounting screw holes 8 for fixed connection.

[0028] Furthermore, the support spring bar 32 is made of spring steel, and the support spring bar 32 provides elastic supporting force to support and protect the protective pipe sleeve 1 and the water supply pipe 2. When receiving external force, it buffers and unloads the force by deformation. The support spring bar 32 can be deformed so that water supply pipes 2 of different diameters can be installed inside, thereby improving applicability.

[0029] When in use, the water supply pipe structure is placed underground through the lifting equipment, the water supply pipe 2 is first hot-melt-jointed through the docking equipment, and then the iron rod is inserted into the inside of the control socket 5, and the regulating sleeve 4 is rotated by the iron rod. When the regulating sleeve 4 rotates, it moves toward the end of the protective pipe sleeve 1 under the action of the thread, and the movement of the regulating sleeve 4 pushes the support kit 6 to move, and the support kit 6 pushes the flange 7 to move, and the flange 7 drives the positioning plug 9 and the guide cone 10 to move, and the end of the guide cone 10 is inserted into the positioning socket 11 on the surface of the adjacent flange 7, and then the flange 7 is continued to be controlled to move outward, and the guide cone 10 and the positioning plug are pushed by the flange 7. The column 9 is fully inserted into the positioning socket 11. As the insertion depth of the guide cone 10 increases, the flange 7 is offset to align the mounting screw hole 8. After the mounting screw hole 8 is aligned, the bolt is inserted into the mounting screw hole 8 to connect and fix the two flanges 7 that are tightly attached, and then it can be buried. In the subsequent use process, when the local soil settles or shifts, the soil presses the protective pipe sleeve 1 to move. When the protective pipe sleeve 1 moves, the support spring bar 32 is compressed and deformed, so that the water supply pipe 2 still maintains its original buried position, thereby preventing the pipe from being offset due to the pressure along the vertical axis of the burial, causing the water supply pipe 2 to be damaged.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
