Description

Technical Field

[0001] The utility model relates to the technical field of pipeline interfaces, in particular to a grouting anti-leakage blocking device for an inspection well pipeline interface. Background Art

[0002] Grouting technology is a method of injecting specific materials into formations or structures to improve their physical and mechanical properties. Grouting at inspection well pipe joints typically uses materials such as cement slurry and chemical slurries, which are injected into the cracks and pores at the joints to fill and consolidate, thereby achieving the purpose of sealing and reinforcement.

[0003] At present, in the existing technology, some tiny leaks may not be discovered in time by other conventional methods, and these tiny leaks may gradually expand during long-term operation, eventually leading to serious leakage problems. Injecting gas and monitoring the changes in air pressure can provide a quantitative evaluation method to determine the sealing performance of the sealing device. In view of this, we propose a grouting anti-leakage sealing device for the inspection well pipeline interface. Utility Model Content

[0006] Slide rail, the support frame is fixedly connected to the slide rail, and the slide rail is provided with a sliding limit assembly;

[0007] A fixed seat is provided on the sliding limit assembly, the fixed seat is fixedly connected to the gas injection leak detector, and the gas injection leak detector is fixedly connected to the connecting shell through a connecting pipe.

[0008] Preferably, the sliding limit assembly includes a sliding plate, a sliding plate is provided on the outer side of the slide rail, a support seat is fixedly connected to the sliding plate, and the fixed seat provided on the sliding limit assembly is used to fix the gas injection leak detector to ensure that the gas injection leak detector maintains a stable position during the operation of the device.

[0009] Preferably, the support seat is elastically connected to the pulling plate through a spring, and the pulling plate is fixedly connected to the limit plate. By pushing the pulling plate outward, the limit plate is driven to stretch outward and clamped with the slide rail to achieve sliding limit locking.

[0010] Preferably, the clamping device includes a clearance groove, and the clearance groove is provided on the surface of the connecting shell.

[0011] Preferably, the outer wall of the connecting shell is fixedly connected with a folding clip plate, and the folding clip plate is clipped into the clearance groove.

[0012] Preferably, a thread groove is provided on the surface of the connecting shell, and the thread groove is threadedly connected to the threaded rod. The threaded connection between the thread groove and the threaded rod can provide additional fastening force, making the connection more firm and reliable.

[0013] The utility model provides a grouting and leak-proof plugging device for inspection well pipeline interface. It has the following beneficial effects:

[0014] (1) The grouting and leak-proof sealing device for the inspection well pipeline interface uses a sliding detection device to push the pulling plate outward, drive the limit plate to stretch outward and release the clamping limit with the slide rail, so that it is easy to slide and use in multiple scenarios. After determining the detection position, the force of pushing the pulling plate is released, and the limit plate is clamped and limited with the slide rail under the reset of the spring. By injecting gas into the interface and monitoring the change in air pressure, it can be accurately judged whether there is a leak at the interface. If there is a leak, the air pressure will drop.

[0015] (2) The grouting and leak-proof sealing device for the inspection well pipe interface flips the connection shell and closes it through the provided clamping device. The clamping of the folding clamping plate and the clearance groove can provide an accurate and firm connection, which can be quickly positioned during installation.

The outer wall of the support frame 1 is provided with a sliding detection device 5, and the sliding detection device 5 is provided with a clamping device 6. The sliding detection device 5 includes a slide rail 51.

The cam 524 is fixedly connected to the support frame 1 and the cam 525 is fixedly connected to the support frame 1. Stretching outward releases the clamping limit of the slide rail 51, making it easy to slide and use in multiple scenarios. A fixed seat 53 is provided on the sliding limit assembly 52, and the fixed seat 53 is fixedly connected to the gas injection leak detector 54. The gas injection leak detector 54 is fixedly connected to the connecting shell 56 through the connecting pipe 55. The gas injection leak detector 54 is specially used to detect leakage at the inspection well pipeline interface, and has high detection accuracy and sensitivity. By injecting gas into the interface and monitoring the air pressure change, it can be accurately determined whether there is a leak at the interface. If there is a leak, the air pressure will drop, and the gas injection leak detector 54 can detect this change and issue an alarm or display relevant information, as well as the degree and location of the leak.

The threaded connection between the threaded groove 63 and the threaded rod 64 can provide additional tightening force, making the connection more firm and reliable, ensuring the accuracy of the connection and avoiding problems such as loose connection or leakage caused by inaccurate installation.

[0031] Push the pull plate 524 outward, and the limit plate 525 is pulled outward to release the clamping limit with the slide rail 51, which is convenient for sliding to achieve multi-scene use. After determining the detection position, release the force of pushing the pull plate 524, and the limit plate 525 is clamped and limited with the slide rail 51 under the reset of the spring 523. By injecting gas into the interface and monitoring the air pressure change, it is possible to accurately determine whether there is a leak at the interface. If there is a leak, the air pressure will drop, and the gas injection leak detector 54 can detect this change and issue an alarm or display relevant information, as well as the degree and location of the leak.
