[0050] The specific embodiment shown below is intended to be a description of the various configurations of the subject technology of the present invention, and is not intended to represent that the subject technology of the present invention can be put into practice. The specific embodiment includes that specific details are intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and apparent to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be put into practice without these specific details.

[0051] Reference Figures 1 to 6 As shown, in a first aspect: a vertical pipeline settlement compensation device comprises an upper section pipe 1 and a lower section pipe 2 matched with the upper section pipe 1;

[0052] The upper tube section 1 is plugged into the lower tube section 2, and a portion of the upper tube section 1 extends into the lower tube section 2;

[0053] A sleeve 3 is provided on the outside of the upper tube section 1, and a compensation space 4 is formed between the sleeve 3 and the upper tube section 1. A portion of the lower tube section 2 extends into the compensation space 4. An upper sealing ring 21 is provided on the upper end of the lower tube section 2. The upper sealing ring 21 divides the compensation space 4 into a compensation chamber 41 and a stuffing chamber 42. The upper sealing ring 21 is provided with a through hole 22 that connects the stuffing chamber 42 with the compensation chamber 41.

[0054] The lower end of the sleeve 3 is provided with a lower sealing ring 5 for sealing the lower end of the stuffing cavity 42 . The lower sealing ring 5 is provided with a material injection port 51 , and a sealing head 52 is provided in the material injection port 51 .

[0055] The filling cavity 42 can be filled with polyurethane flexible sealing material, which is used to seal the gap in the compensation cavity 41, for example, the gap between the upper section pipe 1 and the lower section pipe 2 or the gap between the upper section pipe 1 and the sleeve 3, so that the compensation cavity 41 has certain sealing properties to prevent rainwater leakage.

[0056] The sealing head 52 can be fixed in the injection port 51 by bonding, or the sealing head 52 can be fixed in the injection port 51 by other means. The sealing head 52 and the injection port 51 should have sealing properties to prevent leakage of the polyurethane flexible sealing material.

[0057] During the assembly process, the lower sealing ring 5 is first sleeved on the lower tube section 2 by elastic deformation, and then the upper tube section 1 is assembled with the sleeve 3, and then the lower tube section 2 is assembled with the upper tube section 1.

[0058] After the upper section pipe 1 and the lower section pipe 2 are assembled, the lower sealing ring 5 and the sleeve 3 are assembled. In order to facilitate the assembly of the upper section pipe 1, the lower section pipe 2 and the sleeve 3.

[0059] Reference Figures 1 to 6In some embodiments, a one-way valve is arranged in the through hole 22 to allow the filler in the filler cavity 42 to enter the compensation cavity 41, and the one-way valve is opened when the lower section pipe 2 moves downward relative to the upper section pipe 1 to make the pressure in the compensation cavity 41 lower than the pressure in the filler cavity 42.

[0060] The one-way valve can also be omitted, and the through hole 22 can be left open when the filler in the filler cavity 42 does not need to be sealed, for example, when the filler is a water-solidified material.

[0061] In some embodiments, the sleeve pipe 3 is fixed to the upper section pipe 1 by a connecting block 6.

[0062] The connecting block 6 is adhered to the inner wall of the sleeve pipe 3, and the connecting block 6 is adhered to the outer wall of the upper section pipe 1.

[0063] The connecting block 6 is at least three, and the at least three connecting blocks 6 are evenly arranged along the circumferential direction of the sleeve pipe 3.

[0064] The connecting block 6 can also be replaced by a connecting ring. When a connecting ring is used, the connecting ring has a larger contact area with the upper section pipe 1 and the sleeve pipe 3, thereby increasing the connection strength between the sleeve pipe 3, the connecting block 6, and the upper section pipe 1.

[0065] Referring to Figures 1 to 6 In some embodiments, the upper sealing ring 21 is adhered to the lower section pipe 2, and the upper end surface of the upper sealing ring 21 is flush with the upper end surface of the lower section pipe 2.

[0066] The polyurethane flexible sealing material in the compensation cavity 41 is easy to enter the gap between the upper section pipe 1 and the lower section pipe 2, and can effectively seal the gap between the upper section pipe 1 and the lower section pipe 2, so that rainwater is not easy to leak.

[0067] In some embodiments, the lower sealing ring 5 is adhered to the lower end of the sleeve pipe 3.

[0068] The lower end of the sleeve pipe 3 is provided with a fixing rib 31 for fixing the lower sealing ring 5, and the lower sealing ring 5 is provided with a fixing groove matched with the fixing rib 31.

[0069] The outer wall of the sleeve pipe 3 and the inner wall of the sleeve pipe 3 are both provided with a fixing rib 31, the fixing rib 31 is an integral structure with the sleeve pipe 3, and the cross-sectional shape of the fixing rib 31 is an arc shape larger than a semicircle.

[0070] By arranging the fixing rib 31, the lower sealing ring 5 and the sleeve pipe 3 have higher connection strength, and the lower sealing ring 5 and the sleeve pipe 3 are not easy to separate.

[0071] In one or more embodiments, a groove 53 is provided on the surface of the lower sealing ring 5 that contacts the lower tube section 2 , and the groove 53 is recessed into the surface of the lower sealing ring 5 that contacts the lower tube section 2 .

[0072] By providing the groove 53 , the lower sealing ring 5 can be easily sleeved on the lower pipe section 2 , so that the upper pipe section 1 , the sleeve 3 and the lower pipe section 2 can be easily assembled.

[0073] Reference Figures 7 to 13 As shown, in the second aspect: a vertical pipeline settlement compensation device includes an upper pipeline 7 and a lower pipeline 8 matched with the upper pipeline 7;

[0074] The upper pipe 7 is plugged into the lower pipe 8, and a portion of the upper pipe 7 extends into the lower pipe 8;

[0075] An upper outer tube 71 is provided outside the upper pipe 7, and a compensation chamber 9 is formed between the upper outer tube 71 and the upper pipe 7. The upper outer tube 71 is fixed to the upper pipe 7 by an upper connecting piece 72. The upper connecting piece 72 separates the compensation chamber 9 into an upper chamber 91 and a lower chamber 92 that are independent of each other. The upper connecting piece 72 is provided with a hole portion 73, and the upper chamber 91 and the lower chamber 92 are communicated through the hole portion 73. The upper chamber 91 is filled with a flexible sealing material.

[0076] A portion of the lower pipe 8 extends into the lower cavity 92. The portion of the lower pipe 8 located in the lower cavity 92 is provided with a sealing ring 81. When the lower pipe 8 moves downward relative to the upper pipe 7, the volume of the lower cavity 92 increases so that the pressure in the lower cavity 92 is lower than the pressure in the upper cavity 91. The flexible sealing material in the upper cavity 91 enters the lower cavity 92 under the action of atmospheric pressure.

[0077] In practice, rainwater pipes are usually installed outside high-rise buildings. Therefore, the rainwater pipes should be easy to assemble, that is, the upper pipe 7 and the lower pipe 8 should be easy to splice.

[0078] Specifically, since the upper pipe 7 is plugged into the lower pipe 8, and a portion of the lower pipe 8 extends into the lower cavity 92, the sealing ring on the lower pipe 8 has a certain elastic deformation ability. During assembly, it is only necessary to plug the upper pipe 7 and the lower pipe 8, and the assembly of the upper pipe 7 and the lower pipe 8 is very convenient.

[0079] The sealing ring 81 on the lower pipe 8 forms a piston-like structure in the lower cavity 92. When the lower pipe 8 sinks, that is, when the lower pipe 8 moves downward relative to the upper pipe 7, the sealing ring 81 located in the lower cavity 92 moves downward at the same time, and the volume of the lower cavity 92 increases. At this time, the pressure in the lower cavity 92 is less than the pressure in the upper cavity 91. Under the action of atmospheric pressure, the flexible sealing material in the upper cavity 91 is squeezed into the lower cavity 92. The flexible sealing material entering the lower cavity 92 seals the gap between the upper pipe 7 and the lower pipe 8, making it difficult for rainwater to leak.

[0080] The upper pipe 7 and the upper connecting piece 72 may be an integral structure, and the upper connecting piece 72 and the upper outer pipe 71 may be an integral structure.

[0081] Reference Figures 7 to 13 As shown, in some embodiments, there are at least three circles of the sealing ring 81 , and at least three circles of the sealing ring 81 are evenly arranged along the length direction of the lower pipe 8 , and at least three circles of the sealing ring 81 are bonded to the lower pipe 8 .

[0082] In some embodiments, a lower outer tube 82 is provided outside the lower pipe 8, and the lower outer tube 82 is fixed to the lower pipe 8 by a lower connecting piece 83. The lower connecting piece 83 is provided at the lower end of the lower outer tube 82. A portion of the upper outer tube 71 extends into the lower outer tube 82. A sealed cavity 84 is formed between the upper outer tube 71 and the lower outer tube 82. A floating sealing ring 85 is provided in the sealed cavity 84 to prevent rainwater leakage. The width of the sealed cavity 84 gradually narrows from bottom to top, and the density of the floating sealing ring 85 is less than the density of rainwater.

[0083] When the flexible sealing material located in the lower cavity 92 cannot effectively seal the lower cavity 92, rainwater leaked from the lower cavity 92 will enter the sealing cavity 84. At this time, when too much rainwater enters the sealing cavity 84 and accumulates, the liquid level in the sealing cavity 84 rises, causing the floating sealing ring 85 to rise with the liquid level. Since the width of the sealing cavity 84 gradually narrows from bottom to top, at this time, the floating sealing ring 85 is tightly attached to the upper outer tube 71 and the lower outer tube 82 respectively to form an effective seal, thereby preventing rainwater from leaking.

[0084] The lower outer tube 82 and the lower connecting piece 83 are an integrated structure, and the lower connecting piece 83 and the lower pipe 8 can also be an integrated structure.

[0085] Reference Figures 7 to 13As shown, in some embodiments, the floating sealing ring 85 is provided with a groove body 851, and the floating sealing ring 85 is also provided with a mouth 852 communicated with the groove body 851, the mouth 852 is set downward, and the width of the groove body 851 is greater than the width of the mouth 852. Rainwater leaked into the sealing cavity 84 enters the groove body 851 through the mouth 852, and the rainwater in the groove body 851 squeezes the floating sealing ring 85 so that the floating sealing ring 85 contacts the outer wall of the upper outer tube 71 and the inner wall of the lower outer tube 82 respectively.

[0086] The rainwater in the sealing cavity 84 enters the groove body 851 through the mouth 852. When the rainwater in the sealing cavity 84 has a certain pressure, the pressure of the rainwater in the groove body 851 is equal to the pressure of the rainwater in the sealing cavity 84. At this time, the pressure formed by the rainwater in the groove body 851 squeezes the floating sealing ring 85, so that the side walls of the floating sealing ring 85 are respectively tightly attached to the upper outer tube 71 and the lower outer tube 82, further making the floating sealing ring 85 have better sealing performance and rainwater is not easy to leak.

[0087] The above describes the subject technical solution and corresponding details of the present invention. It can be understood that the above description is only some implementation plans of the subject technical solution of the present invention, and some details may be omitted during its specific implementation.

[0088] In addition, in some embodiments of the above invention, multiple embodiments may be implemented in combination. Due to space limitations, various combination schemes are not listed one by one. Those skilled in the art can freely combine and implement the above embodiments as needed in specific implementation to obtain a better application experience.

Obviously, these details still fall within the scope covered by the subject technical solution of the present invention without departing from the subject technical solution of the present invention.
