[0023] The present invention will be further described and illustrated below in conjunction with the accompanying drawings and specific embodiments. The technical features of each embodiment of the present invention can be combined accordingly without conflict.

[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The technical features of the various embodiments of the present invention may be combined accordingly, provided that there is no conflict between them.

[0025] In the description of the present invention, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or indirectly connected, that is, there are intermediate elements. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0026] In the description of this utility model, it should be understood that the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0027] Example

[0028] Combine Figure 1 As shown, this embodiment provides a fixing device for blocking an airbag, comprising a bracket assembly, a buckle assembly, and a support assembly. The buckle assembly is mounted on the top of the bracket assembly, and the support assembly is mounted on the bottom of the bracket assembly. It should be noted that the device is made of steel.

[0029] In some embodiments, the bracket assembly includes at least four telescopic members, and the four telescopic members are arranged vertically, and the adjacent members are preferably connected to form a rectangular parallelepiped shape. Specifically, each telescopic member includes a first telescopic rod 1, a second telescopic rod 2, and a third telescopic rod 3, wherein the first telescopic rod 1, the second telescopic rod 2, and the third telescopic rod 3 are installed and arranged in sequence from top to bottom, and the first telescopic rod 1 is movable and retractable inside the second telescopic rod 2, and the third telescopic rod 3 is also movable and retractable inside the second telescopic rod 2. Furthermore, two adjacent telescopic members are connected by a transverse fixing rod 4, which is specifically installed on two adjacent second telescopic rods 2. This arrangement is to avoid affecting the telescopic effect of the first telescopic rod 1 and the third telescopic rod 3 during the telescopic process. The first telescopic rod 1 and the second telescopic rod 2 of the same telescopic member are provided with a connecting sleeve 5 on the outside of the telescopic movable position. The connecting sleeve 5 is soft in nature. The contact positions of the connecting sleeve 5 with the first telescopic rod 1 and the second telescopic rod 2 can be rotated or other power to generate friction between the first telescopic rod 1 and the connecting sleeve 5, and between the second telescopic rod 2 and the connecting sleeve 5. At the same time, the rotation causes a relative displacement between the first telescopic rod 1 and the second telescopic rod 2. This relative displacement can be pulled upward or pressed downward, thereby adjusting the overall height of the first telescopic rod 1 and the second telescopic rod 2. Similarly, the third telescopic rod 3 and the second telescopic rod 2 of the same telescopic member are provided with a connecting sleeve 5 on the outside of the telescopic movable position. The connecting sleeve 5 has a flexible nature. The contact position between the connecting sleeve 5 and the third telescopic rod 3 and the second telescopic rod 2 can generate friction between the third telescopic rod 3 and the connecting sleeve 5, and between the second telescopic rod 2 and the connecting sleeve 5 through rotation or other dynamic forces. At the same time, the rotation causes a relative displacement between the third telescopic rod 3 and the second telescopic rod 2. This relative displacement can be pulled up or pressed down, thereby adjusting the overall height of the third telescopic rod 3 and the second telescopic rod 2. It should be noted that without using external force to rotate any telescopic rod, no relative displacement will occur between the first telescopic rod 1 and the second telescopic rod 2, or between the second telescopic rod 2 and the third telescopic rod 3. This telescopic structure can adjust the height of the entire fixing device according to the depth of the pipe 14 to be suitable for various types of large pipes 14. Furthermore, the telescopic structure can also select other existing telescopic devices that can be extended and retracted, which will not be described in detail here.

[0030] In this embodiment, at least one snap assembly is provided on the top of each telescopic member, and the snap assembly includes a snap ring 7, a slot 8, and an elastic member, wherein the snap ring 7 is snapped onto the upper end of the first telescopic rod 1, and the snap ring 7 is also provided above the connecting sleeve 5. The snap ring 7 is connected to the slot 8 through a connecting block. Preferably, the slot 8 is a U-shaped structure, and the elastic member is movably connected to the slot 8. Specifically, the U-shaped slot 8 includes a first side, a second side, and a third side. The second and third sides are respectively connected to the first side, and the connecting block is connected to the first side. The tensioner includes a pressure block 9, a push rod 10, and a handle 11. The handle 11 is mounted on the top of one end of the push rod 10, and the pressure block 9 is mounted on the bottom of the other end of the push rod 10. The pressure block 9 is located within the slot of the U-shaped structure. The second side has a threaded hole, and the push rod 10 has a threaded structure. The push rod 10 is threadedly connected to the threaded hole. By rotating the handle 11, the push rod 10 is driven into the slot 8, which in turn drives the pressure block 9 at the bottom of the push rod 10 to squeeze close to the pipe 14. At this time, the third side is located inside the pipe 14, and the second side is located outside the pipe 14. The two sides are fixed to the upper and lower surfaces of the sidewall of the pipe 14. It should be noted that because the connecting sleeve 5 is provided between the first and second telescopic rod sections 1 and 2, the clamping ring 7 clamped on the connecting sleeve 5 will not fall off. The connecting sleeve 5 also serves to limit the clamping ring 7.

[0031] In this embodiment, the support assembly is composed of several self-adhesive foot supports 6, one of which is mounted below the third telescopic rod section 3 at the bottom of each telescopic member. Specifically, the foot supports 6 are preferably trapezoidal in shape. The foot supports 6 at the bottom of the same telescopic member are located below the connecting sleeve 5 at the point where the second and third telescopic rod sections 2 and 3 are extended.

[0032] In this embodiment, a support frame 12 can also be installed on the side of the bracket assembly facing the airbag 13. The support frame 12 can have multiple rods intersecting to form a cross-shaped structure or other shapes, which can generate resistance to the airbag 13. It should be noted that the support frame 12 is located between the transverse fixing rods 4, that is, the upper and lower ends of the support frame 12 are respectively fixed to the fixing frames above and below it.

[0033] Reference Figure 2 and Figure 3As shown, this device needs to add valves, flow meters and other components on the basis of the already running pressurized pipeline 14. In order to ensure that the impact on sewage operations is reduced during the entire construction process, measures such as blocking air bags 13 need to be taken at the upstream and downstream positions of the additional device to ensure that the construction of the additional valves and other components is in a dry land state. After the pressure of the pressurized pipeline 14 of the upstream pump station project is stopped and the water pressure of the existing sewage pipeline 14 tends to be stable, a circular hole 15 of appropriate size is opened above the pipeline 14 at the location of the blocking air bag 13 according to actual needs. After the opening is completed, the air bag 13 is blocked and a frogman is used to go down the well to block the air bag 13. After the air bag 13 is blocked and inflated, a blocking air bag 13 fixing device is added at the rear end to fix the air bag 13 to prevent the air bag 13 from slipping under the pressure of the upstream.

[0034] During the blocking operation, the foot support 6 is located at the bottom of the pipe 14, and the end of the telescopic member with the buckle assembly is extended outside the circular hole 15. At this time, the third side surface is located inside the pipe 14, and the second side surface is located outside the pipe 14. By rotating the handle 11, the push rod 10 is driven into the slot 8, which in turn drives the pressure block 9 at the bottom of the push rod 10 to press close to the pipe 14, thereby fixing the entire fixing device at the position corresponding to the circular hole 15 of the pipe 14, thereby fixing the blocking airbag 13.

[0035] The above is only an embodiment of the present invention, and its description is relatively specific and detailed, but it should not be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, various modifications and improvements can be made without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
