It can quickly provide fire-fighting water sources in the initial stage of a fire, contain the spread of the fire, and ensure personal and property safety. However, the tunnel environment is complex and the space is narrow, and the installation and maintenance of water supply pipelines face many challenges, especially the design and use of support devices. Traditional support devices often require a large number of tools, the installation process is complex and time-consuming, and they are not suitable for rapid deployment and adjustment in the narrow tunnel space.

[0003] In order to improve the installation efficiency, reduce the dependence on professional tools, and adapt to the narrow operation space of the tunnel, the prior art requires a support device for tunnel fire-fighting water supply pipelines that is convenient, simple to operate, and occupies little space. This device should be able to provide reliable support in a limited space to ensure the stability and safety of the pipeline, while simplifying the installation and maintenance process, reducing construction time and labor intensity. This need has spawned the research and development of new support devices to meet the efficient and reliable requirements of the tunnel fire-fighting system.

[0004] In summary, it is particularly necessary to develop a new type of support device for tunnel fire-fighting water supply pipelines that does not require a large number of tools, is convenient to operate, and is suitable for installation in a narrow space. Summary of the Invention

[0024] For the purpose of facilitating the solution of problems, an embodiment of the present utility model provides a support device for a tunnel fire fighting water supply pipeline. The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-3 , this embodiment provides a support device for a tunnel fire fighting water supply pipeline, including

[0026] a sheath 100 that can be installed on the tunnel wall. The support sleeve 200 is arranged on the sheath 100 through a connecting mechanism. The sheath 100 is installed on the wall, and the sheath 100 and the support sleeve 200 are spliced together through the connecting mechanism, so as to fix the pipeline between the two.

[0027] The connecting mechanism includes a screw 301 arranged at the connecting end of the support sleeve 200, and a rotatable thread groove 302 arranged at the connecting end of the sheath 100. The screw 301 can be threadedly combined with the thread groove 302 to complete the connection action of the support sleeve 200 and the sheath 100. By inserting the screw 301 into the thread groove 302, the thread groove 302 is driven to rotate under the combined action of extrusion and threads, and then the threaded connection between the screw 301 and the thread groove 302 is realized, and the connection between the two is realized by means of the threads.

[0028] Specifically, there are two screws 301 at each connecting end of the support sleeve 200, and two thread grooves 302 at each connecting end of the sheath 100. The thread directions of adjacent thread grooves 302 are opposite. In this way, when the screw 301 and the thread groove 302 are combined with each other, two forces in two directions will be generated to make the connection between the sheath 100 and the support sleeve 200 tighter.

[0029] Specifically, a gear 400 is arranged at the end of each thread groove 302, and a blocking block 500 that can move horizontally back and forth and can be meshed with the gear 400 is arranged at each connecting end of the sheath 100. By means of the meshing of the gear 400 and the blocking block 500, the thread groove 302 on the surface of the gear 400 is locked, and then the connection between the thread groove 302 and the screw 301 is locked.

[0030] Specifically, the connection ends of the sheath 100 and the support sheath 200 are wrapped with elastic pads. When the sheath 100 and the support sheath 200 are connected, the elastic pads on their surfaces will squeeze each other, thereby deforming, and generating elastic force under the action of the deformation, thereby making the screw 301 and the thread groove 302 fit more closely, further increasing the overall strength.

[0031] Specifically, the outer thread of the screw 301 is provided with a notch, and the notch on the thread can increase the friction of the threaded connection, thereby improving the anti-loosening performance. The notch design can provide a self-locking function to a certain extent, preventing the nut from rotating and loosening without external force.

[0032] When using:

[0033] First install the sheath 100 on the wall of the area to be installed. At this time, place the water supply pipe on the inner circumference of the sheath 100, pull out the blocker 500, let it detach from the surface of the gear 400, align the screw 301 on the sheath 200 with the thread groove 302, and insert it upward. During the insertion process, the threads of the screw 301 and the inner threads of the thread groove 302 contact and squeeze each other. Under the action of the threads and squeezing, the thread groove 302 begins to rotate. During the rotation process, the threads of the two are combined. After the support sheath 200 is installed to the specified position, push the blocker 500 to make it mesh with the gear 400 again, thereby locking the thread groove 302, and the connection is completed.

[0034] Although the embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
