Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pipeline maintenance equipment, in particular to a water conservancy pipeline repair device. Background Technique

[0002] Water conservancy pipelines play important roles in guiding water flow, such as water diversion and drainage. They are important building materials in water conservancy projects. Due to the easy occurrence of cracking and damage during long-term use of water conservancy pipelines, special pipeline repair devices are needed for their maintenance.

[0003] Traditional water conservancy pipeline repair devices mainly repair the outer surface of pipelines. The repair of the pipeline interior is relatively inconvenient. Generally, special drivable repair devices are used to move inside the pipeline and perform repairs. However, the specifications and shapes of some repair devices are mostly fixed, and they can only repair pipelines with specific specifications and sizes, resulting in low usage diversity. Moreover, when the fixed support shape moves inside the pipeline, it is easy to cause secondary damage to the inner wall during collisions, which instead reduces the usage effect. At the same time, when repairing the inner wall, the impurities existing in the pipeline are easily mixed with the repair adhesive, reducing the repair effect of the device.

[0004] Therefore, we propose a water conservancy pipeline repair device to solve the above problems. Content of the Utility Model

It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments may be combined with each other.

[0030] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0031] The following describes a water conservancy pipeline repair device provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0032] Embodiment 1:

[0033] Combined with Figures 1 - 3 As shown, a water conservancy pipeline repair device provided by the present utility model

[0034] Specifically, it includes an installation box body 1 and a pipeline main body 2. Four groups of support pads 7 are symmetrically arranged near the inner side walls of the upper and lower ends of the installation box body 1 close to the pipeline main body 2. A plurality of moving wheels 12 are rotatably installed on the inner sides of the support pads 7. At one end of the four groups of support pads 7 close to the outer side surface of the installation box body 1, a first connection block 9 is installed. In the middle of the interior of the installation box body 1, an installation sleeve plate 11 is installed. There are multiple first rods 8 between the installation sleeve plate 11 and the first connection block 9. In the middle of the multiple first rods 8, a second connection block 22 is installed. One end of the second connection block 22 is rotatably connected to a second rod 18. A repair guide joint 3 and an airbag sleeve 4 are respectively arranged on the left and right sides of the installation box body 1. A liquid injection compression box 14 and an air injection compression barrel 10 respectively penetrate through the left and right side surfaces of the installation box body 1. One end of each of the liquid injection compression box 14 and the air injection compression barrel 10 is penetrated and embedded with an extrusion rod 17. One end of the extrusion rod 17 is connected with a limit sliding rod 20. The limit sliding rod 20 not only facilitates the sleeving of the extrusion spring 21 and the installation connection sleeve 19, but also limits the movement of the installation connection sleeve 19 and plays a role of connecting and pushing the extrusion rod 17. An extrusion spring 21 is sleeved on the outer side of the limit sliding rod 20. On one side of the extrusion spring 21, an installation connection sleeve 19 is slidably sleeved on the outer side of the limit sliding rod 20. The other end of the extrusion rod 17 is connected with a compression plunger 16 inside the liquid injection compression box 14 and the air injection compression barrel 10. Sealing cotton plugs 15 are respectively embedded at the joints of the outer side surface of the installation box body 1 and the multiple first rods 8. The two ends of the multiple first rods 8 are respectively rotatably sleeved on the inner sides of the first connection block 9 and the installation sleeve plate 11. The other end of the second rod 18 is rotatably connected to the outer side of the installation connection sleeve 19. The two ends of the extrusion spring 21 respectively abut against the side end surfaces of the extrusion rod 17 and the installation connection sleeve 19. With the use of the above-mentioned components, the multiple first rods 8 rotate and adjust along the installation sleeve plate 11, which also drives the movement of the second rod 18 and enables the installation connection sleeve 17 to squeeze the extrusion spring 21. In this way, the first rod 8 drives the support pad 7 to stretch and contract, playing an adjusting role and facilitating the movement of the repair device in pipeline main bodies 2 of various different specifications. This not only improves the diversity of the overall use of the repair device but also expands the application range.

[0035] Embodiment 2:

[0036] Combined with Figure 2 and Figure 3 as shown, on the basis of Embodiment 1,

[0037] Specifically, through the use of the components in Embodiment 1, due to the elastic effects of the support pad 7, the airbag sleeve 4, and the extrusion spring 21, when being squeezed by the pipeline main body 2, their elastic forces slow down the friction during the movement of the repair device and also reduce the damage to the pipeline main body 1, improving the use effect.

[0038] Embodiment 3:

[0039] Combined Figures 1 - 3 As shown, in the above embodiments,

[0040] Specifically, one end of the repair guide joint 3 is connected to the left end face of the installation box body 1 and abuts against the left end face of the liquid injection compression box 14. A liquid guide hole groove 13 is formed inside the repair guide joint 3. The liquid guide hole groove 13 is mainly used to facilitate the introduction of the repair liquid into the repair liquid guide cotton 5. A repair liquid guide cotton 5 that abuts against the inner side face of the pipeline main body 2 is sleeved on the outer side face of the repair guide joint 3. One end of the liquid guide hole groove 13 is communicated with the liquid injection compression box 14, and the other end is communicated with the repair liquid guide cotton 5. An airbag sleeve 4 is sleeved on the outer side of the air injection compression barrel 10. A cleaning brush plate 6 that abuts against the inner side face of the pipeline main body 2 is sleeved on the outer side face of the airbag sleeve 4. Air injection ducts 23 are symmetrically penetrated and installed at the abutting position of the airbag sleeve 4 and the air injection compression barrel 10. The use of each of the above components includes the components in the first embodiment. Through the movement and extrusion of the second rod 18 and through each component, the compression plunger 16 is compressed inside the liquid injection compression box 14 and the air injection compression barrel 10, so that the repair liquid is introduced into the repair liquid guide cotton 5. At the same time, gas is filled into the airbag sleeve 4 to make the cleaning brush plate 6 fit with the pipeline main body 1, and cleaning and repair are carried out one after the other, avoiding the mixing of the repair liquid and impurities and improving the overall repair effect of the repair device.

[0041] Working principle and usage process of the present utility model: Firstly, during use, the repair device is inserted into the pipeline main body 2 through an external transmission mechanism. The driving mechanism inside the mounting sleeve plate 11 drives the transmission shaft to drive a plurality of first rods 8 to rotate and adjust along the mounting sleeve plate 11, so that the second rod 18 connected to the middle of the first rod 8 by the second connection block 22 pushes the mounting connection kit 17 to squeeze the compression spring 21 along the limit sliding rod 20. In this way, the first rod 8 drives the support backing plate 7 to stretch and contract, playing an adjustment role, facilitating the movement of the repair device in pipeline main bodies 2 of various different specifications. This pull-rod type stretching and adjusting structure improves the overall diversity of the repair device and expands its application range. Secondly, during use, when the above components operate, due to the elastic effects of the support backing plate 7 sleeved outside the moving wheel 12, the airbag sleeve 4 in the middle of the cleaning brush 6, the repair liquid guide cotton 5 outside the repair adapter, and the compression spring 21, when being squeezed by the pipeline main body 2 during the movement of the repair device, their elastic acting forces slow down the friction during movement and also reduce the damage to the pipeline main body 1, improving the usage effect. Finally, during use, when the above components operate, the second rod 18 pushes the mounting connection kit 19 to squeeze the compression spring 21 along the limit sliding rod 20, which also squeezes the extrusion rod 17, and compresses the compression plunger 16 inside the liquid injection compression tank 14 and the gas injection compression barrel 10, guiding the repair liquid into the repair liquid guide cotton 5 through the liquid guide hole groove 13. At the same time, gas is filled into the airbag sleeve 4 through the gas injection conduit 23 to make the cleaning brush 6 fit with the pipeline main body 1. In this way, cleaning and repair are carried out one after the other, avoiding the mixing of the repair liquid and impurities and improving the overall repair effect of the repair device.

[0042] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
