Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection, specifically a high airtight fire protection pipeline. Background Technology
[0002] Firefighting pipelines refer to pipeline materials used in firefighting to connect firefighting equipment and materials and to transport firefighting water, gas or other media. Due to special requirements, firefighting pipelines have special requirements for thickness and material, and are painted red. They transport firefighting water. During use, personnel usually need to connect the firefighting pipelines and fire hoses before carrying out firefighting operations.
[0003] Currently, when connecting fire hoses, if the fire hose has poor airtightness, it will increase the pressure loss in the system, resulting in a decrease in water pressure. This will affect the water spraying effect, especially when long-distance water spraying is required. The drop in water pressure may reduce the spraying range, making it difficult to effectively extinguish the fire. In addition, it may also cause leakage between the fire hose and the fire hose, resulting in waste of water resources. Therefore, a high airtight fire hose is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of existing technologies and avoid the problem that poor airtightness of fire-fighting pipelines affects the fire-fighting effect, this utility model proposes a high airtightness fire-fighting pipeline.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a high airtight fire pipe, including a fire hydrant, a fire pipe body is fixedly connected to the right side of the fire hydrant, a fire hose is clamped to the side of the fire pipe body away from the fire hydrant, a sealing plate is fixedly installed on the surface of the fire pipe body, and a sealing component is provided inside the sealing plate.
[0006] The sealing assembly includes a driven rod slidably connected inside the fire hydrant body. A connecting plate is fixedly connected to the side of the driven rod near the fire hydrant. A pressure spring is fixedly connected to the surface of the connecting plate near the center of the fire hydrant body. A push rod is fixedly connected to the surface of the connecting plate away from the center of the fire hydrant body. A steel cable is fixedly connected to the surface of the push rod away from the connecting plate. A groove is formed on the surface of the sealing plate away from the center of the fire hydrant body. A rotating rod is rotatably connected inside the groove. Winding wheels are fixedly connected to the surfaces at both ends of the rotating rod. A rotating plate is fixedly connected to the middle of the rotating rod surface. A torsion spring is fixedly connected to the rotating rod surface.
[0007] Preferably, the sealing plates are in four sets and are circumferentially distributed on the surface of the fire pipe body. The four sealing plates contact each other in turn, and the four sealing plates contact the surfaces of the fire pipe body and the fire hose to seal the connection between the fire pipe body and the fire hose.
[0008] Preferably, the two ends of the driven rod are located on the left and right sides of the fire pipe body, respectively, and the end face of the driven rod is adapted to contact the end face of the fire hose. When the fire hose is engaged with the surface of the fire pipe body, the fire hose will push the driven rod to move.
[0009] Preferably, the end of the pressure spring away from the connecting plate is fixedly installed on the surface of the fire pipe body, and the push rod is slidably connected inside the sealing plate. When the driven rod is pushed by the fire hose, it will cause the connecting plate to stretch the pressure spring.
[0010] Preferably, the end of the steel cable away from the push rod is wound and connected to the surface of the winding wheel, the rotating plate is located inside the groove, the rotating plate is adapted to abut against the fire hose, and when the push rod moves inside the sealing plate, the push rod will pull the steel cable, causing the steel cable to pull the rotating rod to rotate.
[0011] Preferably, the driven rod has an inner groove on the side near the fire-fighting pipe body, and an abutment rod is rotatably connected inside the inner groove. A return spring is fixedly connected to one end of the abutment rod near the inside of the inner groove.
[0012] Preferably, the abutment rod and the end face of the fire-fighting pipe body on the side away from the fire hose are adapted to make contact. When the driven rod is pushed by the fire hose until the inner groove moves to the outside of the fire-fighting pipe body with the driven rod, the abutment rod rotates under the action of the return spring and abuts against the inner wall of the fire-fighting pipe body, thereby limiting the position of the driven rod.
[0013] The advantages of this utility model are:
[0014] This invention connects the fire hose and the fire pipeline body. A sealing plate then seals the connection point. A rotating plate abuts against the side of the fire hose furthest from the fire pipeline body, ensuring a stable connection and improving airtightness. Simultaneously, a contact rod abuts against the end face of the fire pipeline body, limiting the position of the driven rod and consequently the position of the rotating plate. This further stabilizes the fire hose, enhancing the airtightness of the connection and ensuring water pressure during spraying, thus guaranteeing the safety of fire suppression.

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 scope of protection of the present utility model.
[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0025] This application discloses a highly airtight fire-fighting pipeline. (Refer to...) Figure 1 and Figure 2A high airtight fire-fighting pipeline includes a fire hydrant 1, a fire-fighting pipeline body 2 fixedly connected to the right side of the fire hydrant 1, a fire hose 3 clamped to the side of the fire-fighting pipeline body 2 away from the fire hydrant 1, a sealing plate 4 fixedly installed on the surface of the fire-fighting pipeline body 2, four sets of sealing plates 4 distributed circumferentially on the surface of the fire-fighting pipeline body 2, the four sealing plates 4 contacting each other in turn, the four sealing plates 4 contacting the surfaces of the fire-fighting pipeline body 2 and the fire hose 3 to seal the connection between the fire-fighting pipeline body 2 and the fire hose 3, and a sealing component 5 is provided inside the sealing plate 4;
[0026] Reference Figures 3-6 The sealing assembly 5 includes a driven rod 51 slidably connected inside the fire hydrant 1 body 2. The two ends of the driven rod 51 are located on the left and right sides of the fire hydrant 1 body 2, respectively. The end face of the driven rod 51 is adapted to contact the end face of the fire hose 3. When the fire hose 3 is engaged with the surface of the fire hydrant 1 body 2, the fire hose 3 will push the driven rod 51 to move. A connecting plate 52 is fixedly connected to the side of the driven rod 51 closest to the fire hydrant 1. A pressure spring 53 is fixedly connected to the surface of the connecting plate 52 closest to the center of the fire hydrant 1 body 2. A push rod 54 is fixedly connected to the surface of the connecting plate 52 furthest from the center of the fire hydrant 1 body 2. The end of the pressure spring 53 furthest from the connecting plate 52 is fixedly installed on the surface of the fire hydrant 1 body 2. The push rod 54 is slidably connected inside the sealing plate 4. The driven rod 51 is engaged with the fire hose 3. When pushed, the connecting plate 52 will stretch the pressure spring 53. A steel cable 55 is fixedly connected to the surface of the push rod 54 away from the connecting plate 52. A groove 56 is opened on the surface of the sealing plate 4 away from the center of the fire pipe body 2. A rotating rod 571 is rotatably connected inside the groove 56. A winding wheel 572 is fixedly connected to both ends of the rotating rod 571. A rotating plate 573 is fixedly connected to the middle of the surface of the rotating rod 571. A torsion spring 574 is fixedly connected to the surface of the rotating rod 571. The end of the steel cable 55 away from the push rod 54 is wound and connected to the surface of the winding wheel 572. The rotating plate 573 is located inside the groove 56. The rotating plate 573 and the fire hose 3 are adapted to abut against each other. When the push rod 54 moves inside the sealing plate 4, the push rod 54 will pull the steel cable 55, so that the steel cable 55 pulls the rotating rod 571 to rotate.
[0027] Reference Figures 3-4The driven rod 51 has an inner groove 581 on the side near the fire pipe body 2. An abutment rod 582 is rotatably connected inside the inner groove 581. A return spring 583 is fixedly connected to one end of the abutment rod 582 near the inside of the inner groove 581. The abutment rod 582 and the end face of the fire pipe body 2 away from the fire hose 3 are adapted to contact each other. When the driven rod 51 is pushed by the fire hose 3 until the inner groove 581 moves to the outside of the fire pipe body 2 with the driven rod 51, the abutment rod 582 rotates under the action of the return spring 583 and abuts against the inner wall of the fire pipe body 2, thereby limiting the position of the driven rod 51.
[0028] Working principle: The user can interlock the fire hose 3 and the fire pipe body 2. Since the driven rod 51 extends to the outside of the fire pipe body 2, as the fire hose 3 approaches the fire pipe body 2, it will push the driven rod 51 to move away from the fire hose 3. At this time, the driven rod 51 will drive the connecting plate 52 to move accordingly. The connecting plate 52 will then stretch the pressure spring 53, and simultaneously drive the push rod 54 to move. At this time, the push rod 54 slides inside the sealing plate 4 away from the fire hose 3. When moving, the steel cable 55 is pulled, which in turn pulls the winding wheel 572 to rotate. At this time, the winding wheel 572 drives the fixedly connected rotating rod 571 to rotate. When the rotating rod 571 rotates, it pulls the torsion spring 574 and accumulates elastic force. At this time, the rotating rod 571 drives the rotating plate 573 to rotate. The rotating plate 573 rotates to the outside of the push rod 54 until the rotating plate 573 rotates to abut against the side of the fire hose 3 away from the fire pipe body 2. At this time, under the action of the rotating plate 573, the fire hose 3 is more firmly connected to the fire pipe body 2 and will not fall off.
[0029] During the process of the driven rod 51 being pushed by the fire hose 3, when the inner groove 581 of the driven rod 51 moves to the inside of the fire pipe body 2, the abutment rod 582 no longer contacts the inside of the fire pipe body 2. Therefore, the abutment rod 582 will rotate under the action of the return spring 583 until the abutment rod 582 abuts against the inner wall of the fire pipe body 2. At this time, under the limitation of the return force of the pressure spring 53 and the abutment rod 582, the positions of the driven rod 51 and the push rod 54 are limited, that is, the position of the rotating plate 573 is also limited, so that the rotating plate 573 stably supports the fire hose 3.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
