[0022] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" does not mean the same embodiment at different places in this specification, nor is it an embodiment that is independent of or mutually exclusive of other embodiments. The utility model provides the following embodiments.

[0025] As shown by Figure 1 and Figure 2 , it is a structure schematic view of the water testing device in the embodiment, the device includes an outer frame 1, a positioning frame 2, a sealing plate 3 and an injection pressure pipe 4, the outer frame 1 is symmetrically provided with the positioning frame 2, the outer frame 1 is provided with the sealing plate 3 on the side of the positioning frame 2, the sealing plate 3 is provided with the injection pressure pipe 4 at the end, the sealing plate 3 is provided with the sealing mechanism 5 on the side opposite to the side of the injection pressure pipe 4.

[0026] During use, the steel pipe to be tested is hoisted and transported onto the outer frame 1. Then, the positioning frame 2 is used to support and position the steel pipe. After that, as the sealing plate 3 moves, the two sides of the steel pipe are sealed and shielded. Finally, water is injected into the steel pipe through the injection pipe 4. As the pressure increases, after reaching the predetermined pressure and maintaining it for a certain period of time, the steel pipe is observed to see if there is any leakage. This is used to judge the pressure resistance and sealing performance of the steel pipe.

[0027] From the appendix Figure 3 As shown, this is a structural schematic diagram of the sealing mechanism 5 in this embodiment. The sealing mechanism 5 includes a mounting plate 51, an airbag 52, an air injection port 53, a fixing member 54, and a support member 55. The mounting plate 51 is mounted on the side of the sealing plate 3, and the airbag 52 is mounted on the surface of the mounting plate 51.

The fixing bracket is equidistantly mounted on the surface of the mounting plate 51, and a support spring is mounted on one side of the end of the fixing bracket.

[0028] During use, when the sealing plate 3 approaches the end of the steel pipe, the outer edge of the airbag 52 fits against the inner wall of the steel pipe. As the sealing plate 3 moves, the mounting plate 51 and the sealing plate 3 compress the entire steel pipe, enhancing the sealing performance when the sealing plate 3 and the mounting plate 51 fit against the steel pipe. Then, due to the presence of gas inside the airbag 52, the airbag 52 expands as a whole. The support member 55 defines the overall shape of the airbag 52, making the cross-section of the airbag 52 trapezoidal. When the water pressure inside the steel pipe rises, the water source first compresses the trapezoidal surface of the airbag 52, causing the support spring to deform and driving the outer wall of the airbag 52 to fit tightly against the inner wall of the steel pipe, thus achieving a seal at the openings at both ends of the steel pipe.
