Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, specifically to an outdoor fire-resistant fire hydrant. Background Technology

[0002] Existing outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings. They mainly provide water for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network for fire fighting. They can also be directly connected to fire hoses and nozzles to extinguish fires. They are one of the important fire-fighting facilities for extinguishing fires. Chinese patent discloses an outdoor fire hydrant (publication number CN207959360U), which has already described the fire hydrant in detail, so it will not be repeated here. However, existing outdoor fire-resistant fire hydrants have a problem in use: the sealing cap and the water outlet are connected by threads. In the event of an emergency fire, the sealing cap needs to be turned multiple times, which affects the water output efficiency and makes it difficult to control the fire in a timely manner. This is inconvenient to use and has room for improvement. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in this embodiment, an outdoor fire-resistant hydrant includes a hydrant body 1, a hydrant cap 2 installed on the top of the hydrant body 1, multiple water outlets 3 provided on the top surface of the hydrant body 1, a sealing cap 4 provided at the opening of the water outlet 3, an automatic drain valve 6 provided at the bottom of the hydrant body 1, a flange B8 fixed to the outer side of the end of the automatic drain valve 6, a flange A7 fixed to the outer side of the bottom of the hydrant body 1, mounting bolts 9 provided at equal angles on the surface of the flange A7, the outer diameters of the flanges B8 at both ends of the automatic drain valve 6 are not equal, and the middle of the outer surface of each sealing cap 4 is flush with the water outlet. Chains 5 are installed between the bottom of the outer surface of the water outlet 3. A connecting assembly is provided inside the opening of the water outlet 3. The connecting assembly includes an installation rod 11 installed inside the opening of the water outlet 3. The top of the installation rod 11 is located on the outer top of the water outlet 3. An installation insertion hole 22 for the installation rod 11 to pass through is opened on the top surface of the water outlet 3. A connecting groove 13 for the installation rod 11 to engage is symmetrically opened on the top and bottom of the outer surface of the sealing cover 4 facing the inside of the water outlet 3. The cross-section of the installation rod 11 is "T" shaped. The vertical end of the installation rod 11 is... The diameter of the mounting rod 11 is equal to the width of the opening of the connecting slot 13. A limiting spring 12 is sleeved on the top outer side of the mounting rod 11. A connecting plate 15 is symmetrically fixed on the top outer side of the mounting rod 11 inside the outlet 3. The inner wall of the connecting slot 13, which is opened on the top surface of one end of the sealing cover 4, is symmetrically provided with a first limiting slot 14 for the connecting plate 15 to engage. The connecting plate 15 is set perpendicular to the mounting rod 11. The surface width of the connecting plate 15 is greater than the inner wall depth of the first limiting slot 14. An installation groove 1 is opened at the bottom of the inner wall of the opening of the outlet 3. 7. A metal spring 18 is installed inside the mounting groove 17. A second limiting groove 16 is opened on the bottom surface of one end of the sealing cover 4. The second limiting groove 16 communicates with the connecting groove 13 on the bottom surface of one end of the sealing cover 4. One end of the metal spring 18 is engaged inside the second limiting groove 16, which facilitates the installation and connection of the sealing cover 4 and the water outlet 3. In case of emergency fire fighting, the sealing cover 4 can also be quickly opened for drainage. It is convenient and quick to operate, which can improve the operating efficiency of firefighters and facilitate timely control of the fire. It has good practicality.

[0022] like Figure 1 and Figure 5As shown, a protective component is provided at the bottom outer side of the hydrant body 1. The protective component includes a protective sleeve 10 fitted onto the bottom outer side of the hydrant body 1. A through groove 20 is symmetrically opened on the top outer surface of the protective sleeve 10. Limiting protrusions 21 are symmetrically installed on the bottom outer surface of the hydrant body 1. The side surface of the limiting protrusions 21 is slidably connected to the inner wall of the through groove 20. The bottom of the protective sleeve 10 is engaged with the outside of the flange A7 and flange B8. A rubber ring 19 is installed in the middle of the inner surface of the protective sleeve 10. The surface of the rubber ring 19 is pressed and adhered to the surface of the hydrant body 1. The top surface of the protective sleeve 10 is inclined. The cross-section of the rubber ring 19 is a right-angled trapezoid, which facilitates the external protection of the connection between the hydrant body 1 and the automatic drain valve 6. This prevents the mounting bolts 9 on the surface of the flange A7 from being exposed to the outside, avoiding erosion by rainwater. This also makes it less likely for the mounting bolts 9 to rust or rot. This facilitates the disassembly and relocation of the fire hydrant by firefighters in the future, resulting in good practical effect.

[0023] This utility model provides an outdoor fire-resistant hydrant. Its working principle is as follows: When needed for emergency firefighting, the sealing cover 4 needs to be quickly opened for connection and drainage. First, press the top of the mounting rod 11. The limiting spring 12 on the outer side of the top of the mounting rod 11 will generate a certain rebound force under pressure. Simultaneously, the bottom of the mounting rod 11 will move towards the second limiting slot 16, exerting pressure on the metal spring 18 engaged in the second limiting slot 16. The metal spring 18 will deform and move towards the mounting groove 17. When the bottom of the mounting rod 11 moves towards the second limiting slot 16, the connecting plate 15 on the outer side of the top of the mounting rod 11 will disengage from the first limiting slot 14. At this point, the sealing cover 4 can be pulled towards the outside of the outlet 3, causing the mounting rod 11 to separate from the connecting slot 13 on one end of the sealing cover 4. The sealing cover 4 is then removed, allowing firefighters to quickly connect the water pipe for drainage and firefighting. The operation is convenient and quick, facilitating easy access. High operational efficiency, timely fire control, and good practicality; after the bolt body 1 and automatic drain valve 6 are installed and connected to flange A7 and flange B8 through flange A7, the exterior of flange A7 and flange B8 needs to be protected. First, push the protective sleeve 10 outside the bolt body 1 to move outward to the exterior of flange A7 and flange B8. At the same time, the side surface of the limiting protrusion 21 will slide and connect with the inner wall of the through groove 20 opened on the surface of the protective sleeve 10 until the protective sleeve 10 is completely engaged with the flange. The outer surface of flange A7 and flange B8 is protected by the rubber ring 19 in the middle of the inner wall of the protective sleeve 10, which will press against the surface of the hydrant body 1. The limiting protrusion 21 will engage with the top of the inner wall of the through groove 20. This allows the protective sleeve 10 to protect the outer surface of flange A7 and flange B8, preventing the mounting bolts 9 on the surface of flange A7 from being corroded by rainwater and avoiding rust or rotten threads on the mounting bolts 9. This makes it easier for firefighters to disassemble and move the fire hydrant later, and the practical effect is good.

[0024] 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.
