Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, specifically to a cleanroom embedded fire hydrant structure. Background Technology

[0002] The recessed fire hydrant structure in cleanrooms is an innovative fire protection facility design. It cleverly embeds traditional fire hydrants into the walls or floor, thereby minimizing the occupation of valuable cleanroom space while maintaining the cleanliness and aesthetics of the environment. Fire hoses are also carefully designed and stored, usually made of high-quality pressure-resistant materials and neatly wound in a box for quick deployment when needed. This design not only improves the efficiency of fire hydrant use but also ensures that the environmental requirements of the cleanroom are met, making it a practical and aesthetically pleasing fire protection solution.

[0003] The layout and functional area division of a cleanroom may vary depending on different usage needs, and the location of embedded fire hydrants after installation will also vary accordingly. For example, in some cleanrooms, fire hydrants may need to be installed near the experimental area, while in other cleanrooms, they may need to be installed near the production or storage area. Therefore, in order to ensure that fire hydrants can effectively serve their respective areas, the layout of the pipes must be adjusted accordingly based on the specific installation location of the fire hydrants.

[0004] While the space utilization efficiency of embedded fire hydrants in cleanrooms has been significantly improved during installation, the connection between the built-in valves and pipes and the external water pipes cannot be ignored. Traditional fixing methods, such as the use of rigid brackets or fixing clamps, can provide a certain degree of stability, but they also expose obvious defects. These fixing methods greatly limit the flexibility of the pipes. Once it is necessary to adjust the pipe layout according to the specific usage environment, the operation becomes extremely difficult, which not only increases the installation difficulty, but also significantly increases the workload of subsequent maintenance. Therefore, a new embedded fire hydrant structure for cleanrooms is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-7 This utility model provides a technical solution:

[0030] A cleanroom embedded fire hydrant structure includes a fire hydrant body 1, a fixed pipe 2 fixedly connected to the inner side of the fire hydrant body 1, an angle adjustment component 5 bolted to the right end of the fixed pipe 2, an internal water pipe assembly 3 installed inside the angle adjustment component 5, and an external water pipe assembly 4 slidably connected to the outer side of the internal water pipe assembly 3. The internal water pipe assembly 3 includes a first telescopic pipe body 31, which is integrally fixed with an extension pipe 32. A first rubber ring 33 is fixedly connected to the outer side of the extension pipe 32. The inner side of the retractable tube body 31 is provided with a first connecting channel 34. A ball tube 35 is fixedly connected to the left side of the first telescopic tube body 31. An annular groove 36 is provided on the outside of the ball tube 35. A second rubber sealing ring 37 is fixedly connected to the inner side of the annular groove 36. The external water pipe assembly 4 includes a second telescopic tube body 41. A second connecting channel 42 is provided on the inner side of the second telescopic tube body 41. An extension tube 43 is fixedly connected to the right end of the second telescopic tube body 41. The angle adjustment assembly 5 includes a spherical shell 51. A spherical groove 52 is provided on the inner side of the spherical shell 51.

[0031] As a further implementation of this scheme, a spacer pipe 53 is fixedly connected to the left side of the spherical shell 51, and a flange 54 is fixedly connected to the left side of the spacer pipe 53. Through the above settings, a stable connection base is formed, providing reliable support for the entire device and ensuring the stability of the connection between the fire hydrant and the external water pipe.

[0032] As a further implementation of this solution, flange 54 is fixed to fixed pipe 2 with bolts, and flange 54 is sealed to fixed pipe 2 with a gasket. The interior of spacer pipe 53 is connected to spherical groove 52 and the interior of spacer pipe 53 is connected to the interior of fixed pipe 2. Through the above settings, the bolt fixing method combined with the sealing design of gasket not only ensures the firmness of the connection, but also effectively prevents water leakage, ensuring the sealing and reliability of fire hydrant during use. At the same time, the internal connection design ensures smooth water flow and improves the efficiency of fire hydrant use.

[0033] As a further implementation of this solution, the expansion tube 32 is embedded inside the second connecting channel 42. The outer sides of the expansion tube 32 and the first rubber ring 33 are both in contact with the inner side of the second connecting channel 42. The shape of the ball tube 35 is a hollow sphere. The outer sides of the ball tube 35 and the second rubber sealing ring 37 are both in contact with the inner side of the spherical groove 52. One-third of the volume of the right end of the ball tube 35 protrudes from the outside of the spherical groove 52. The inside of the ball tube 35 is a hollow structure and is connected to the spherical groove 52. Through the above settings, not only is the flexibility and angle adjustment range of the device increased, but the partially protruding design also prevents excessive rotation, ensuring the stability and reliability of the device during the adjustment process. At the same time, it effectively prevents water overflow and ensures the sealing performance of the fire hydrant.

[0034] As a further implementation of this solution, the extension pipe 43 is connected to the second connecting channel 42. The structure of the end of the extension pipe 43 away from the second telescopic pipe body 41 is the same as the structure of the left end of the first telescopic pipe body 31. Through the above settings, it can be fixed to the connection end of the water pipe, ensuring smooth water flow.

[0035] Workflow: When flexibly connecting the fire hydrant body 1 to the water pipe, based on the position between the fire hydrant body 1 and the pipe, hold the second telescopic tube 41 and adjust its position. Adjust the angle of the second telescopic tube 41 according to the position of the water pipe structure. The second telescopic tube 41 will drive the first telescopic tube 31 and the extension tube 32 to move accordingly. During this process, the first telescopic tube 31 will drive the ball tube 35 to rotate around its center. Since the shape of the ball tube 35 and the spherical groove 52 are both spherical, this improves the range and convenience of adjusting the angle of the second telescopic tube 41 and the second telescopic tube 41. The ball tube 35 partially protrudes from the outside of the spherical shell 51 to prevent excessive rotation of the ball tube 35, which would cause the second rubber sealing ring 37 to protrude from the outside of the spherical groove 52. The rubber sealing ring 37 serves to seal the space between the spherical shell 51 and the spherical tube 35, preventing water from overflowing during flow. The sliding arrangement of the first telescopic tube 31 and the extension tube 32 inside the second telescopic tube 41 allows for flexible adjustment based on the distance between the fire hydrant body 1 and the water pipe installation section. When the angle adjustment component 5 at one end of the extension tube 43 is aligned with the installation end of the water pipe, the rubber gasket is placed on the right side of the flange 54 at the right end. At this point, the flange 54 at the right end is fixed to the water pipe with bolts, thus completing the installation. Based on the above principles, the device changes the traditional way of connecting the fire hydrant body 1 and the water pipe. It allows for flexible adjustment of the angle and length of the connection mechanism based on the distance between the fire hydrant body 1 and the water pipe, reducing the difficulty of installation and the workload of subsequent maintenance. It is suitable for fire hydrant installation in clean rooms.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
