Description

Technical Field

[0001] The present invention relates to the technical field of sealing detection, and in particular to a sealing detection device for a prefabricated pipe gallery. Background Art

[0002] Prefabricated pipe gallery is an underground engineering structure used in urban infrastructure construction, which is used to centrally lay municipal utility pipelines (such as electricity, telecommunications, water supply, drainage, gas, heat, etc.). Compared with the traditional pipeline laying method, prefabricated pipe gallery has many advantages, including improving pipeline safety, reducing the number of road excavation, and facilitating maintenance and management.

[0003] The joints and seams of the prefabricated pipe gallery are the weak points of the prefabricated and assembled integrated pipe gallery, and the waterproof performance of the joints is a key technical issue that affects the structural safety and durability of the prefabricated and assembled integrated pipe gallery. After the installation of the pipe gallery, once leakage occurs, sealing inspection will be a very difficult task. Regarding the sealing detection of the joints of the pipe gallery, the air tightness detection method of inflation and pressurization can be used, or the water tightness detection method of water injection and pressurization can be used. When using the above methods for on-site operations, it is necessary to carry out artificial lighting, pressurization control, operation video recording, multi-compartment inspection and other work simultaneously, and at least three inspection personnel are required. The quality of manual inspection mainly depends on the experience, responsibility and carefulness of the workers. The work process is boring and requires a lot of personnel input. By delivering gas or liquid to the air injection hole or water injection hole of the prefabricated pipe gallery to detect air tightness or water tightness, the water after use cannot be recycled, resulting in a waste of water resources. At the same time, water remains at the connection, which is easy to affect the connection of the prefabricated pipe gallery for a long time. Summary of the invention

[0059] Working principle: In order to conduct water tightness detection, after the driving vehicle 1 is moved to a suitable position in the prefabricated pipe gallery, the position of the connecting pipe 63 is adjusted by the moving component 61 on the adjusting frame 6, and the connecting pipe 63 is driven to be located directly above the water injection hole of the prefabricated pipe gallery, and the connecting pipe 63 is driven to descend by the push of the lifting hydraulic cylinder 62, and the plug-in pipe 64 of the connecting pipe 63 is plugged into the water injection hole, and after the adsorption electromagnet 75 is energized, the electromagnetic ring group 73 at the upper end is adsorbed, and the electromagnetic ring group 73 drives the internal magnetically connected conveying pipe 71 to descend, and the connecting spring 72 and the reset spring 74 are stretched;

[0060] After the movable pin 8 in the conveying pipe 71 contacts the connecting block in the plug-in pipe 64 and is pressed, it stretches and contracts, and the moving spring 81 is compressed. At the same time, the push handle 82 on the conveying pipe 71 presses the pressing ring 85 below. After the pressing ring 85 drops, the pressing spring 86 is compressed, and the pressing ring 85 drives the connecting rod 87 to drop, and pulls the sealing arc block 83 hinged with the pin shaft of the connecting rod 87 to deflect and fit the connection between the conveying pipe 71 and the plug-in pipe 64 to seal the connection. The elastic force of the annular spring 84 presses the sealing arc block 83, and the conveying water pump 7 sucks the liquid in the stirring tank 2 and then conveys it into the conveying pipe 71. After entering the plug-in pipe 64 through the conveying pipe 71, it enters the connection of the prefabricated pipe gallery through the water injection hole for water tightness detection. After the water injection is completed, wait for a period of time and observe the reaction of the pressure gauge. The drop in the pressure gauge indicates that there is a leak. The leak is judged by observing whether there is a colored solution flowing out of the connection.

[0061] After the detection is completed, the adsorption electromagnet 75 is powered off and reset under the action of the connecting spring 72 and the reset spring 74. After the movable pin 8 is reset, the water supply is cut off, and the plug-in pipe 64 is connected with the connecting pipe 63. After the recovery water pump 65 is sucked, the water detected at the connection of the prefabricated pipe gallery can be sucked into the water outlet of the recovery water pump 65, filtered through the filter plate 51 and then enters the collection tank 5, and then enters the mixing tank 2 through the collection tank 5 to complete the circulation. After the drive motor 3 is started, the drive shaft 31 is driven to rotate, and the drive shaft 31 drives the drive sleeve 32 to rotate. After the worm on the stirring tank 2 drives the worm gear meshing with it to rotate, it drives the lifting gear 43 to rotate back and forth, drives the rack set 42 to lift, drives the gear on the driving screw 45 to rotate, drives the driving screw 45 to rotate back and forth, drives the driving slider 46 on the driving screw 45 to move back and forth, and drives the driving electromagnet 47 on the driving slider 46 to be magnetically connected with the stirring rack 23, drives the stirring rack 23 to move back and forth, drives the stirring gear 22 to rotate, and the stirring paddle 21 in the stirring tank 2 deflects left and right to stir the water in the stirring tank 2, the dye and the recovered solution;

[0062] When it is necessary to process the impurities on the filter plate 51, the hydraulic cylinder 33 is adjusted to pull the driving sleeve 32 down, so that the gear on the driving sleeve 32 is meshed with the gear on the rotating sleeve 41, and the worm and the worm wheel are disengaged. After the rotating sleeve 41 rotates, the limit frame 44 is driven to rotate and move to the top of the filter plate 51. After the driving electromagnet 47 is magnetically connected to the upper surface of the scraper 52, the movement of the driving slider 46 drives the scraper 52 to move, and the impurities on the filter plate 51 are pushed to the partition 53. After the partition 53 is deflected, the impurities enter the dirt collecting tank 54 below.

[0063] After the air tightness test is performed, air is transported into the air pipeline 91 through the air compressor 9, and then transported into the air injection hole through the air pipeline 91 for air tightness test, which is observed by a pressure gauge.
