[0001] The utility model relates to the technical field of pipeline anti-seepage, in particular to a pipeline wall-penetrating anti-seepage casing. Background Art

[0002] When underground pipelines pass through the walls of valve wells and compensator wells, groundwater with high water pressure often penetrates from the penetration point, causing chemical, electrochemical bacterial corrosion to valve wells, compensator wells, etc. At present, flexible casing anti-seepage technology is adopted, in which the filler is oil-impregnated asbestos rope. This kind of filler is easy to dissolve when immersed in water for a long time, especially when the medium temperature is higher than 80C. The engine oil in the asbestos rope is easy to evaporate, which aggravates the dissolution of the asbestos rope. Water seepage occurs in less than one year of use, and the filler needs to be replaced every year, and the service life is short.

[0003] In order to solve the above problems, a Chinese utility model with publication number "CN2630604Y" discloses a pipeline wall seepage prevention casing, which mainly solves the problems of poor corrosion resistance and short service life of existing pipeline wall seepage prevention casings; it is characterized in that: a pressure cap (5) is placed between the pipeline (2) and the casing (1); a plurality of packings (4) made of polytetrafluoroethylene are clamped between the pressure cap (5) and the clamping table (3) in the casing (1); the pressure cap (5) is fixed to the embedded iron part (6). It has the characteristics of corrosion resistance and long service life

[0004] Although the above-mentioned prior art can achieve good anti-leakage effect, in actual use, the diameter (outer diameter) of the wall-penetrating pipe that can be installed is fixed, and it cannot be used for wall-penetrating pipes of different models (different outer diameters). It has certain limitations, and therefore a pipe wall-penetrating anti-seepage casing is needed. Utility Model Content

[0005] The purpose of the present application is to provide a pipeline wall-penetrating anti-seepage casing to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a pipeline wall-penetrating anti-seepage casing, comprising an anti-seepage casing, a wing ring embedded in the wall is fixed on the outside of the anti-seepage casing, a wall-penetrating pipe is installed on the inside of the anti-seepage casing, and the inside of the anti-seepage casing is provided with an inner convex portion protruding toward the central axis, and the protruding distance of the inner convex portion is the largest in the middle and the smallest at both ends;

[0007] A slide rail that is consistent with the direction of the inner convex part is fixed on the inner wall of the anti-seepage casing, and a trapezoidal wedge is slidably connected to the slide rail. The trapezoidal wedge slides and fits with the inner convex part against the side wall of the inner wall of the anti-seepage casing at the same angle. The trapezoidal wedge is arc-shaped away from the side wall of the anti-seepage casing and is coaxially arranged with the central axis of the anti-seepage casing.

[0008] Preferably, at least three trapezoidal wedges are provided and distributed in a circular array along the central axis of the anti-seepage casing, and at least three slide rails are also provided and correspond one-to-one to the plurality of trapezoidal wedges respectively.

In the utility model, through the arrangement of the trapezoidal wedge and the slide rail, when the through-wall pipe passes through the anti-seepage casing, the user can push the trapezoidal wedge to make the trapezoidal wedge move along the slide rail toward the middle of the inner convex part, and finally make the side wall of the trapezoidal wedge press against the outer wall of the through-wall pipe, so as to limit and fix the through-wall pipe. At the same time, because the slide rail and the inner convex part have the same direction, the distance between the trapezoidal wedge and the through-wall pipe is gradually reduced during the sliding process, so as to facilitate the fixation of different types of through-wall pipes, expand the application range of the pipeline through-wall anti-seepage casing, and make it have good universality.

[0017] 2. In the utility model, through the arrangement of the adjusting ring, the connecting column and the stretching spring, when the user needs to adjust multiple trapezoidal wedges at the same time, the user only needs to push and pull the adjusting ring.

The multiple connecting columns drive the multiple trapezoidal wedges to move synchronously through multiple operating rods, so that the user can adjust the multiple trapezoidal wedges at the same time and achieve synchronous adjustment of the multiple trapezoidal wedges so that the multiple trapezoidal wedges can synchronously clamp, support and limit the wall-penetrating pipes, which is more convenient to use. In this process, the connecting column gradually moves toward the central axis of the anti-seepage casing under the action of the stretching spring, so as to ensure that the trapezoidal wedge can slide smoothly along the slide rail.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0025] Example: Reference Figure 1-4 The pipe wall penetration anti-seepage casing shown comprises an anti-seepage casing 1, a wing ring 11 embedded in the wall is fixed on the outside of the anti-seepage casing 1, a wall penetration pipe 9 is installed on the inside of the anti-seepage casing 1, and an inner convex portion 12 protruding toward the central axis is arranged on the inside of the anti-seepage casing 1, and the inner convex portion 12 has the largest protruding distance in the middle and the smallest protruding distance at both ends;

[0026] A slide rail 4 that is consistent with the inner convex portion 12 is fixed to the inner wall of the anti-seepage sleeve 1, and a trapezoidal wedge 2 is slidably connected to the slide rail 4. The trapezoidal wedge 2 can be made of hard material (hard metal material, hard non-metal material, etc.) or soft material (rubber, etc.) according to actual use requirements. It is mainly used to fit with the wall-penetrating pipe 9 to form a limit. The trapezoidal wedge 2 is slidably fitted with the inner convex portion 12 against the side wall of the inner wall of the anti-seepage sleeve 1 and the angle is consistent. The trapezoidal wedge 2 is arc-shaped away from the side wall of the anti-seepage sleeve 1 and is coaxially arranged with the central axis of the anti-seepage sleeve 1.

[0027] Based on the above structure, after the wall-penetrating pipe 9 passes through the anti-seepage sleeve 1, the user can push the trapezoidal wedge 2 to make the trapezoidal wedge 2 move along the slide rail 4 toward the middle of the inner protrusion 12, and finally make the side wall of the trapezoidal wedge 2 press against the outer wall of the wall-penetrating pipe 9, thereby limiting and fixing the wall-penetrating pipe 9. At the same time, since the slide rail 4 and the inner protrusion 12 have the same direction (both protrude from the middle toward the central axis of the anti-seepage sleeve 1), the distance between the trapezoidal wedge 2 and the wall-penetrating pipe 9 gradually decreases during the sliding process, thereby facilitating the fixation of wall-penetrating pipes 9 of different models (outer diameters), thereby expanding the scope of application of the pipe wall-penetrating anti-seepage sleeve and making it have good universality.

[0028] Furthermore, at least three trapezoidal wedges 2 are provided and distributed in a circular array along the central axis of the anti-seepage casing 1, and at least three slide rails 4 are also provided and correspond one-to-one to the multiple trapezoidal wedges 2 respectively. Through the provision of multiple (at least three) trapezoidal wedges 2 and multiple (at least three) slide rails 4, the user can move the multiple trapezoidal wedges 2 to jointly clamp, support, and limit the wall-penetrating pipe 9, so that the wall-penetrating pipe 9 is coaxial with the anti-seepage casing 1.

[0029] Furthermore, an operating rod 3 is fixed to one end of the multiple trapezoidal wedges 2 away from the middle of the anti-seepage sleeve 1, and the length of the operating rod 3 is greater than half the length of the anti-seepage sleeve 1. Through the setting of the operating rod 3, it is convenient for the user to move the trapezoidal wedge 2, and at the same time, it is convenient to pull out the trapezoidal wedge 2 that is tightly pressed against the wall-penetrating pipe 9, thereby facilitating multiple debugging during the installation of the wall-penetrating pipe 9 to achieve an ideal installation effect.

[0030] Furthermore, an adjustment ring 5 is provided on one side of the anti-seepage casing 1, and the ends of the plurality of operating rods 3 away from the trapezoidal wedge 2 are connected to the adjustment ring 5 through a connecting piece, and the connecting piece includes a connecting column 6, the upper end of the connecting column 6 slides through the adjustment ring 5, the lower end of the connecting column 6 is fixed to one end of the operating rod 3, and a tension spring 7 is fixed to the upper end of the adjustment ring 5, and the upper end of the tension spring 7 is fixed to the upper end of the connecting column 6 through a fixing block;

[0031] Through the arrangement of the adjusting ring 5, the connecting column 6 and the tension spring 7, when the user needs to adjust multiple trapezoidal wedges 2 at the same time, the user only needs to push and pull the adjusting ring 5. When the adjusting ring 5 moves, it drives the multiple connecting columns 6 to move synchronously. The multiple connecting columns 6 drive the multiple trapezoidal wedges 2 to move synchronously through the multiple operating rods 3, so that it is convenient for the user to adjust the multiple trapezoidal wedges 2 at the same time, and realize the synchronous adjustment of the multiple trapezoidal wedges 2 so that the multiple trapezoidal wedges 2 can synchronously form a clamping, supporting and limiting effect on the wall-penetrating pipe 9, which is more convenient to use. During this process, the connecting column 6 gradually moves toward the central axis of the anti-seepage casing 1 under the action of the tension spring 7, so as to ensure that the trapezoidal wedge 2 can slide smoothly along the slide rail 4.

[0032] Furthermore, a cavity 13 is provided in the anti-seepage sleeve 1, and the cavity 13 divides the anti-seepage sleeve 1 into closed inner and outer double-layer sleeves. The anti-seepage sleeve 1 is set as an inner and outer double-layer sleeve, which can further improve the anti-seepage effect of the pipeline wall-penetrating anti-seepage sleeve compared with the existing single-layer anti-seepage sleeve.

[0033] Furthermore, a movable rod 8 is fixed to one side of the adjustment ring 5 close to the anti-seepage sleeve 1. The end of the movable rod 8 away from the adjustment ring 5 slides through one end of the anti-seepage sleeve 1 and is located in the cavity 13. Through the setting of the movable rod 8, the adjustment ring 5 maintains a straight line during movement, thereby avoiding damage to the trapezoidal wedge 2 caused by the displacement of the adjustment ring 5.

[0034] It should be noted that in order to ensure the stability of the wall-penetrating pipe 9 in the anti-seepage casing 1, a trapezoidal wedge 2 that slides along the slide rail 4 can also be set at the other end of the anti-seepage casing 1. The rear end of the trapezoidal wedge 2 is also installed with an operating rod 3, an adjustment ring 5, a connecting column 6, a tension spring 7, a movable rod 8 and other structures. At this time, a blocking block 41 is also provided in the middle of the slide rail 4 to avoid the two trapezoidal wedges 2 from influencing each other, and is used to provide support, clamping and limiting for the other end of the wall-penetrating pipe 9, so as to ensure that the wall-penetrating pipe 9 is coaxially arranged with the anti-seepage casing 1.

[0035] Working principle of the utility model: in daily use, after the wall-penetrating pipe 9 passes through the anti-seepage sleeve 1, the user can push the adjusting ring 5 to make the adjusting ring 5 move toward the side close to the anti-seepage sleeve 1. At this time, the adjusting ring 5 drives the multiple connecting columns 6 to move synchronously, and the multiple connecting columns 6 drive the multiple trapezoidal wedges 2 to move synchronously through the multiple operating rods 3. The multiple trapezoidal wedges 2 move along the multiple slide rails 4 toward the middle of the inner protrusion 12 respectively, and finally make the side walls of the multiple trapezoidal wedges 2 press against the outer wall of the wall-penetrating pipe 9, thereby limiting and fixing the wall-penetrating pipe 9. At the same time, because the slide rail 4 and the inner protrusion 12 have the same direction, the distance between the trapezoidal wedge 2 and the wall-penetrating pipe 9 is gradually reduced during the sliding process, so as to facilitate the fixation of different types of wall-penetrating pipes 9, expand the application range of the pipe wall-penetrating anti-seepage sleeve, and make it have good universality.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
