Description

Technical Field

[0001] The utility model relates to a fire hydrant, in particular to a fire hydrant for municipal engineering. Background Art

[0002] A fire hydrant, a fixed fire fighting facility, mainly functions to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. Fire hydrants can be found everywhere in the city. Most of the fire hydrants for municipal engineering are installed on sidewalks and roadsides to provide fire-fighting water for firefighters during the rescue process.

[0003] With the rapid development of modern industry, the greenhouse effect and the urban heat island effect are becoming more and more serious. Especially in summer, the weather is hot and the temperature rises. Some flammable substances are extremely likely to cause fires in a high-temperature environment. Once a fire breaks out in the city, it will cause great losses. Generally, the existing fire hydrant and the fire hose are connected by threaded rotation. When connecting, generally, firefighters thread the connection end of the fire hose with the docking port of the fire hydrant and rotate the connection end of the fire hose to effectively connect it with the connection end of the fire hydrant. This method has certain drawbacks in use, such as slow connection efficiency and firefighters having to exert more effort.

[0004] Therefore, we need to design a fire hydrant for municipal engineering with an efficient connection between the fire hose and the fire hydrant. Summary of the Utility Model

[0005] In order to overcome the drawback that the existing fire hydrant is connected by threaded rotation and the connection efficiency of rotating the connection end of the fire hose and the connection end of the fire hydrant is slow, the technical problem of the utility model is to provide a fire hydrant for municipal engineering with an efficient connection between the fire hose and the fire hydrant.

[0006] To solve the above technical problem, the utility model provides such a fire hydrant for municipal engineering, which includes a fire hydrant body, a water outlet pipe, a threaded sleeve, and a tightening mechanism. A plurality of water outlet pipes are installed around the fire hydrant body. One end of each water outlet pipe is rotatably installed with a threaded sleeve, and a tightening mechanism for accelerating the tightening of the water pipe is arranged around the threaded sleeve.

[0007] Preferably, the tightening mechanism includes a mounting ring, a first gear, a second gear, and a toothed ring. The first gear is installed on the outer wall of the threaded sleeve. The mounting ring is installed outside the water outlet pipe. The second gear is installed in the mounting ring through a central shaft. The toothed ring is rotatably installed at one end of the mounting ring. The toothed ring meshes with the second gear, and the second gear meshes with the first gear.

[0008] Preferably, it further includes a protective shell, a mounting block, a wedge block, a connecting rod and an elastic member. A protective shell is provided on the gear ring. One side of the top of the protective shell is provided with a mounting block. A wedge block is slidably mounted in the mounting block. One end of the wedge block away from the protective shell is provided with an elastic member. There are several connecting rods around the elastic member, and the connecting rods all slidably penetrate through one side of the wedge block.

[0009] Preferably, it further includes a rotating shaft and a protective cover. The protective cover is rotatably mounted on one side of the top of the protective shell through the rotating shaft.

[0010] Preferably, it further includes a rotating handle. A rotating handle is mounted outside the gear ring.

[0011] The beneficial effect of the present utility model is that by rotating the rotating handle, the gear ring is driven to rotate. Through the meshing of the gear ring with the second gear and the meshing of the second gear with the first gear, the first gear drives the threaded sleeve to rotate, so that the threaded sleeve is quickly connected to the interface end of the fire hose, realizing the function of quickly and efficiently connecting the fire hydrant and the fire hose.

[0019] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0020] A fire hydrant for municipal engineering, as Figure 1 and Figure 2 shown, includes a fire hydrant body 1, a water outlet pipe 101, a threaded sleeve 2 and a tightening mechanism. Three water outlet pipes 101 are installed on the side of the fire hydrant body 1. One end of each water outlet pipe 101 is rotatably installed with a threaded sleeve 2, and a tightening mechanism for accelerating the tightening of the water pipe is arranged around the threaded sleeve 2.

[0021] As Figure 2 and Figure 3 shown, the tightening mechanism includes a mounting ring 201, a first gear 3, a second gear 4 and a toothed ring 5. The first gear 3 is installed on the outer wall of the threaded sleeve 2, and the mounting ring 201 is installed on the outside of the water outlet pipe 101. The second gear 4 is installed in the mounting ring 201 through a central shaft. A toothed ring 5 is rotatably installed at one end of the mounting ring 201 away from the water outlet pipe 101. The toothed ring 5 meshes with the second gear 4, and the second gear 4 meshes with the first gear 3.

[0022] As Figure 4 and Figure 6 shown, it further includes a protective shell 7, a mounting block 8, a wedge block 9, a connecting rod 10 and an elastic member 11. A protective shell 7 is arranged on the top of the toothed ring 5. A mounting block 8 is installed on one side of the top of the protective shell 7. A wedge block 9 is slidably installed in the mounting block 8. The wedge block 9 plays a certain role in fixing the water pipe. One end of the wedge block 9 away from the protective shell 7 is installed with an elastic member 11. The second elastic member 11 is a spring or elastic rubber. Here it is a spring. There are 4 connecting rods 10 around the elastic member 11, and the connecting rods 10 all slidably penetrate through one side of the wedge block 9.

[0023] As Figure 4 and Figure 5 shown, it further includes a rotating handle 6, a rotating shaft 12 and a protective cover 13. The rotating handle 6 is installed outside the toothed ring 5. The rotating handle 6 is convenient for better rotating and tightening the water pipe. The protective cover 13 is rotatably installed on one side of the top of the protective shell 7 through the rotating shaft 12. The protective cover 13 plays a role in preventing other items from falling into the water outlet pipe 101.

[0024] The staff rotates to uncover the protective cover 13, inserts the water pipe. Under the elastic force of the elastic member 11, the elastic member 11 is compressed, and the wedge block 9 moves outwards along the connecting rod 10 until the thread on the water pipe can contact the threaded sleeve 2. Hold the water pipe and rotate the rotating handle 6. The rotating handle 6 drives the gear ring 5 to rotate. At this time, the gear ring 5 meshes with the second gear 4, and the second gear 4 meshes with the first gear 3, driving the first gear 3 to rotate. The threaded sleeve 2 inside the first gear 3 rotates in the opposite direction to the thread on the water pipe, so that the water pipe and the water outlet pipe 101 are quickly tightened. After the water pipe is completely inserted and tightened, the elastic member 11 rebounds, and the wedge block 9 returns to its original position to clamp the water pipe.

[0025] When the staff needs to remove the water pipe 101, pull the conical body with a hole dug on the wedge block 9. At this time, the wedge block 9 is pulled out, rotate the rotating handle 6 to separate the thread on the water pipe from the threaded sleeve 2, take out the water pipe, and cover the protective cover 13.

[0026] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
