[0002] In recent years, the construction projects of industrial industrial parks have gradually increased, the demand for various box-shaped water tanks has gradually increased, and batches of box-shaped water tanks have been put into use. As a box-shaped water tank, the stored water is used for industrial production or the recycling of industrial wastewater. Therefore, extremely strict requirements are imposed on the self-waterproof performance of the water tank structure. On the one hand, it is necessary to prevent industrial water from being polluted by the outside world, and on the other hand, it is also necessary to prevent the industrial water in the tank from polluting the surrounding soil and water bodies due to leakage. Therefore, before the box-shaped water tank is handed over, a strict water tightness test must be carried out to ensure the tightness of the pipeline part of the water tank.

[0023] The following embodiments can be understood as a detailed explanation of the partial structure or related working principle of the new technical solution, or can also be understood as explaining the structure or working principle of a larger scope of the new type through the combination of embodiments.
[0024] Embodiment 1
[0025] A fixture for temporarily plugging pipe fittings in a box-shaped water tank, as Figures 1-3 shown, includes a first plugging system. The first plugging system includes a fixing plate 1, a moving plate 5, a through-threaded screw 3, and a nut 9. The middle of the inner surface of the fixing plate 1 is welded to one end of the through-threaded screw 3. A threaded hole is provided in the middle of the moving plate 5. The through-threaded screw passes through the threaded hole and is screwed to the moving plate 5. A rubber cushion layer 2 is provided at the inner end of the fixing plate 1, and a wear-resistant layer 6 is provided at the inner end of the movable plate. A nut 9 is screwed on the rod body of the through-threaded screw 3 located outside the moving plate 5.
[0026] As Figure 2 、 3 shown, both the fixing plate 1 and the moving plate 5 are circular plate structures. A plurality of first stiffening plates 4 are uniformly welded between the inner end of the fixing plate 1 and between the inner surface of the fixing plate 1 and the outer wall of the through-threaded screw 3. The first stiffening plates 4 are used to improve the structural stability between the fixing plate and the through-threaded screw.
[0027] As Figure 1 、 3 shown, a boss 10 is welded to the middle of the outer end of the fixing plate 1. A plurality of second stiffening plates 11 are uniformly welded around the axis between the boss 10 and the outer surface of the fixing plate 1.
[0028] As Figure 1 、 2 shown, a sleeve 8 is welded to the middle of the outer end of the moving plate 5. The through-threaded screw 3 passes through the sleeve 8. A plurality of third stiffening plates 7 are welded around the axis between the sleeve 8 and the outer surface of the moving plate 5.
[0029] In this embodiment, when in use, as Figure 1 shown, the through-threaded screw is passed through the pipe fitting 12. The rubber cushion layer 2 on the inner surface of the fixing plate 1 is pressed against one end of the pipe fitting 12. The moving plate is rotated so that the wear-resistant layer 6 on it presses against the other end of the pipe fitting 12, thereby achieving the closure of both ends of the pipe fitting. Finally, the nut is tightened so that it presses against the end of the sleeve. Among them, the first stiffening rib plate, the second stiffening rib plate, the third clamping rib plate, the boss, the sleeve, and the nut are all force-bearing structures of the first plugging system, and the purpose is to improve its structural stability and avoid deformation or local damage during use.
[0030] Embodiment 2
[0031] It should be noted that the pipe fittings can achieve the sealing effect only through the rubber cushion layer. However, due to the possible unevenness of the pipe fitting ports, there may also be leakage caused by the poor contact between the rubber cushion layer and the pipe fitting ports. Based on this, this embodiment discloses:
[0032] As Figure 4 shown, the fixture further includes a second sealing system, and the second sealing system includes an airbag sealing mechanism that is screwed to the through-threaded screw 3 and is located between the fixed plate 1 and the moving plate 5.
[0033] As Figure 4 shown, the airbag sealing mechanism includes a fixed seat 14 screwed on the through-threaded screw 3. The cross-section of the fixed seat 14 is a "convex" structure, and an annular airbag 15 is fixedly connected to the fixed seat 14.
[0034] Embodiment 3
[0035] Based on Embodiment 2, as Figure 4 shown, a gas injection nozzle (not shown in the figure) is connected to the root of the outer surface of the annular airbag 15. The sealing can be achieved by inflating to press the outer wall of the annular airbag against the inner wall of the pipe fitting.
[0036] Embodiment 4
[0037] Based on Embodiments 2 and 3, as Figure 4 shown, the annular airbag 15 is provided with an extrusion device.
[0038] As Figure 4 shown, the extrusion device is an extrusion cylinder 16 coaxially arranged with the through-threaded screw 3 and sleeved outside the through-threaded screw 3. One end of the extrusion cylinder 16 is screwed or welded to the inner surface of the moving plate 5, and an annular pressing plate 17 is welded to the other end of the extrusion cylinder 16. The annular pressing plate 17 is used in cooperation with the annular airbag 15.
[0039] In this embodiment, after the moving plate 5 is pressed against the end of the pipe fitting 12, the annular pressing plate 17 presses the annular airbag 15 to achieve the sealing of the inner wall of the pipe fitting 12 by the annular airbag 15.
[0040] Embodiment 5
[0041] Based on Embodiments 2 - 4, as Figure 4 shown, the fixed seat 14 and the annular airbag 15 fixed thereon are provided with multiple models according to the differences in the inner diameters of the pipe fittings 12 to be sealed. Before use, the corresponding fixed seat and annular airbag 15 can be replaced according to the model of the pipe fitting.
