[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a new type of building fire protection pipeline anti-seepage device, including a pipe body 1, which serves as a transportation channel for fire protection media, and transports fire protection resources from a water source or storage facility to various areas in the building that require fire protection. A flange 2 is fixedly connected to the outside of the pipe body 1, providing an interface for the connection between the pipes, and is connected with bolts, and a sealing strip is used for connection and sealing. The pipe body 1 and the flange 2 are provided with two groups, and the two groups of pipe bodies 1 and flanges 2 are symmetrically arranged. A protective mechanism is provided on the outside of the flange 2, and the protective mechanism includes a protective component and a fixing component. The protective component includes a retaining ring 31, which plays a role of blocking and guiding. It cooperates with the installation frame to prevent the fire protection medium from leaking at the connection of the flange 2 and flowing freely, and limits the possible seepage of the medium to a certain range. At the same time, it provides a fitting basic structure for the seal 1 34 and the seal 2 35, so that the seal can better play a sealing role and facilitates the positioning and installation of the seal.
[0033] Reference Figure 3 - Figure 5The retaining ring 31 is provided with two groups, and the two groups of retaining rings 31 are respectively provided on the outside of the two groups of flanges 2. The retaining ring 31 is fixedly connected to the outside of the flange 2. A seal 34 is provided on the outer side of the upper part of the retaining ring 31. The inclined surface on the inner side of the seal 34 can increase the contact area and the degree of fit with the retaining ring 31. After installation, the seal 34 can effectively fill the possible gap between the retaining ring 31 and the upper mounting frame 32 to prevent the fire-fighting medium from seeping from above. A groove is provided on the lower side of the seal 34, and an upper mounting frame 32 is provided on the outer wall of the upper side of the seal 34, which cooperates with the lower mounting frame 33 to form a closed protective space, wrapping the seal inside, providing an installation position for the seal 34, and through the rotation connection with the lower mounting frame 33, the entire protective assembly can be stably installed on the outside of the connection between the two groups of flanges 2.
[0034] Reference Figure 4 - Figure 6 The upper mounting frame 32 is rotatably connected to the lower mounting frame 33 at the rear side, and a protective space is constructed together with the upper mounting frame 32. The inner wall of the lower mounting frame 33 is clamped with a seal 2 35. A protrusion is provided on the upper part of the seal 2 35. The protrusion provided on its upper part cooperates with the groove of the seal 1 34, further enhancing the sealing effect and preventing the fire-fighting medium from seeping out from below. It works together with the seal 1 34 to fully guarantee the sealing of the connection between the flange 2 and reduce the aging degree of the sealing strip. The inner side of the seal 2 35 covers the outer wall of the lower part of the retaining ring 31 to ensure that the seal 2 35 can be accurately positioned and in close contact with the retaining ring 31. The inner sides of the seal 1 34 and the seal 2 35 are inclined surfaces.
[0035] Reference Figure 1 The fixing assembly includes a fastening bolt 41, which is arranged through the front inner wall of the upper mounting frame 32 and the lower mounting frame 33. The lower part of the fastening bolt 41 is threadedly connected with a nut 42, and the upper part of the nut 42 is fitted on the lower part of the lower mounting frame 33, thereby connecting the upper mounting frame 32 and the lower mounting frame 33. Through the threaded connection with the nut 42, the upper mounting frame 32 and the lower mounting frame 33 can be tightly fixed together, so that the seal 1 34 and the seal 2 35 maintain a stable sealing state on the outside of the flange 2, reducing the aging degree of the sealing strip and ensuring that the protective assembly can effectively perform its anti-water seepage function.
[0036] Reference Figure 1 - Figure 3, an observation component is provided on the outside of the upper mounting frame 32 and the lower mounting frame 33, and the observation component includes an observation window 5, which is respectively provided on the inner wall of the upper mounting frame 32 and the lower mounting frame 33, and is set to a transparent material, so that the inspection personnel can directly observe the situation of the flange 2 connection without removing the protective component. During daily inspection or when water seepage is suspected, the observation window 5 can be used to quickly determine whether water seepage occurs in the fire protection pipe, and potential safety hazards can be discovered in time so that corresponding maintenance or treatment measures can be taken to ensure the normal operation of the fire protection pipe system.
[0037] Working principle: When in use, the retaining ring 31 cooperates with the upper mounting frame 32 and the lower mounting frame 33 to block and guide the firefighting medium that may leak out, and confines it to the range defined by the retaining ring 31.
[0038] Then, seal 1 34 and seal 2 35 fit tightly with retaining ring 31 through their inner inclined surfaces. At the same time, the groove on the lower side of seal 1 34 and the protrusion on the upper part of seal 2 35 fit together, increasing the sealing contact area and improving the sealing effect, sealing the connection of flange 2 and effectively preventing the leakage of fire-fighting medium.
[0039] By tightening the nut 42, the upper mounting frame 32 and the lower mounting frame 33 are tightly fixed together, thereby applying stable pressure to the seal 1 34 and the seal 2 35 to ensure that they always maintain a good sealing state on the outside of the flange 2. Even when the fire protection pipe is affected by external factors such as pressure fluctuations and vibrations, the sealing effect can be effectively maintained to prevent water seepage.
[0040] During routine maintenance and inspection, inspectors can directly observe the flange 2 connection through the observation window 5 without disassembling the protective components. If water seepage occurs in the fire protection pipe during operation, the inspectors can discover it in time through the observation window 5, and then quickly determine the problem and take corresponding maintenance or treatment measures to ensure that the fire protection pipe system is always in a normal and reliable operating state, providing solid protection for the building fire safety.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
