Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, specifically to a fire hydrant with intelligent flow monitoring to prevent jetting. Background Technology

[0002] Fire hydrants are fixed fire-fighting facilities whose main function is to control combustibles, isolate oxidizers, and eliminate ignition sources. They are divided into indoor and outdoor fire hydrants. Outdoor fire hydrants are mainly used by fire trucks to draw water from municipal water supply networks or outdoor fire water supply networks for firefighting. They can also be directly connected to hoses and nozzles for firefighting. Therefore, indoor and outdoor fire hydrant systems are also one of the important fire-fighting facilities for extinguishing fires.

[0003] According to CN221118650U, a fire hydrant with intelligent flow monitoring for preventing water jetting is provided. It includes a base and a hydrant body located on top of the base. A connecting flange is fixedly connected to the bottom of the hydrant body, and a flange is provided at the top of the base. The connecting flange and the flange are correspondingly connected and fixed with bolts. A monitoring component is fixedly connected to the surface of the hydrant body. A sliding groove is formed on the inner wall of the hydrant body, and an elastic telescopic rubber sheet is slidably connected inside the sliding groove. Springs are fixedly connected to both the upper and lower ends of the elastic telescopic rubber sheet, with one end of the spring fixedly connected to the hydrant body. A hydrant cap is fixedly connected to the top of the hydrant body, and a rotating shaft is threaded to the top of the hydrant cap. A movable plug is provided at the bottom of the rotating shaft, passing through the hydrant cap. The movable plug is movably adapted to the elastic telescopic rubber sheet. The movable plug can resist the elastic telescopic rubber sheet from sliding to both sides to block the water flow or squeeze the water flow to both sides to buffer it, reducing the water hammer effect and protecting the equipment and pipelines.

[0004] Because of their simple structure, existing fire hydrants cause water to gush out of the outlet pipe when opened by staff due to the sudden pressure of the water rushing upwards, making them inconvenient to use. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1 , Figure 3 and Figure 4 This utility model provides a technical solution: a fire hydrant with intelligent flow monitoring for preventing water jetting, including a main pipe 1 and a water outlet pipe 2. To prevent water jetting from the fire hydrant, a water outlet pipe 2 is fixedly connected to the right side of the outer wall of the main pipe 1. A rotating assembly is provided on the inner wall of the water outlet pipe 2. The rotating assembly includes a flow-blocking cylinder 301. A fixing block 302 is provided at the connection between the outer wall of the flow-blocking cylinder 301 and the inner wall of the water outlet pipe 2. A flow-blocking ring 303 is provided on the right side of the outer wall of the flow-blocking cylinder 301. A moving pipe 304 is provided on the inner wall of the flow-blocking ring 303. A water outlet hole 305 is opened on the right side of the outer wall of the moving pipe 304. A fixing rod 306 is fixedly connected to the inner wall of the outer wall of the moving pipe 304. A movable rod 307 is rotatably connected to the top, and a rotating rod 308 is rotatably connected to the left side of the outer wall of the movable rod 307. A rotating shaft 309 is fixedly connected inside the rotating rod 308. The rotating shaft 309 is rotatably connected to the water outlet pipe 2 and to the flow-blocking cylinder 301. The flow-blocking ring 303 is fixedly connected to the inner wall of the water outlet pipe 2, and the movable pipe 304 is slidably connected to the flow-blocking ring 303. By setting the rotating component, the operator can manually rotate the rotating block 4 during the use of the fire hydrant to adjust the flow rate of the water inside the fire hydrant, so that the water inside will not gush out, protecting the equipment and pipelines and facilitating the operation of the operator.

[0023] Please see Figure 1 , Figure 2 and Figure 3 To facilitate the opening of fire hydrants by staff, a rotating block 4 is fixedly connected to the front end of the outer wall of the rotating shaft 309. A water outlet 5 is provided at the corresponding position of the outer wall of the flow-blocking cylinder 301 and the inner wall of the water outlet pipe 2. A screw rod 6 is rotatably connected inside the main pipe 1. A rotating disk 7 is fixedly connected to the top of the outer wall of the screw rod 6. A baffle 8 is fixedly connected to the bottom of the outer wall of the screw rod 6. An installation disk 9 is provided at the lower part of the outer wall of the main pipe 1. A fixing ring 10 is provided above the installation disk 9. A controller 11 is fixedly connected to the outer wall of the fixing ring 10. By setting the screw rod 6 and the rotating disk 7, it is convenient for staff to open and close the fire hydrants. The fixing ring 10 and the controller 11 can monitor the water flow. The fixing ring 10 is installed and easy for staff to disassemble.

[0024] Working principle: When the staff uses the fire hydrant, they manually rotate the rotating block 4 to the left, which drives the rotating shaft 309 to move. The rotating rod 308 rotates counterclockwise. At this time, the moving rod 307 moves to the left, which drives the fixed rod 306 to move to the left. The moving tube 304 moves to the left in the flow-blocking cylinder 301 at the same time. When the moving tube 304 continues to move to the left to the appropriate position, the water outlet 5 and the water outlet 305 correspond. When the water flows through the water outlet pipe 2, it is blocked by the flow-blocking cylinder 301. After passing through the water outlet 5 and the water outlet 305, it enters the moving tube 304. At this time, the moving tube 304 collects the water bubbles in the center of the flow channel and eliminates energy through collision, which can effectively prevent water from gushing.

[0025] When the staff wants to open the fire hydrant, the staff manually rotates the rotating disk 7, which drives the lead screw 6 to rotate. At this time, the baffle 8 moves upward with the rotation of the lead screw 6. When the baffle 8 moves upward, the water flows through the main pipe 1 and flows out through the outlet pipe 2. At the same time, the controller 11 monitors the internal flow rate. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] 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.
