Description

Technical Field

[0001] The utility model belongs to the technical field of fire hydrants, and in particular relates to a fire hydrant with a detection mechanism. Background Art

[0002] Fire hydrants, also known as fire hydrants, are a type of fixed fire-fighting facility. Their main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. Fire hydrants are divided into indoor fire hydrants and outdoor fire hydrants. Indoor fire hydrants are used to supply water to the fire scene through indoor pipe networks. They are indoor fixed fire-fighting facilities in factories, warehouses, high-rise buildings, public buildings, and ships. They are usually installed in fire hydrant boxes and are used in conjunction with equipment such as fire hoses and water guns. Outdoor fire hydrants are water supply facilities installed on the fire-fighting water supply network outside the building. They are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire-fighting water supply network to extinguish fires. They can also be directly connected to water hoses and water guns to discharge water for fire extinguishing. Fire hydrants are simple and convenient to operate. Due to the cold weather in winter, the fire-fighting water in the fire hydrant body is easy to freeze, or when the water supply end is blocked, when a fire occurs, if the hydrant body with frozen fire-fighting water is connected to the drainage water hose, it will affect the normal water supply of the fire hydrant, delay the time for disaster relief and rescue, and cause unnecessary losses. Therefore, it is necessary to detect the water pressure of fire hydrants on a daily basis. However, the existing fire hydrant pressure detection method is usually to slowly open the fire hydrant to observe whether there is water flowing out of the fire hydrant. This method is easy to wet the ground, causing inconvenience, and it is impossible to observe the water pressure well. If there is a lack of pressure, it cannot be detected. Another detection method is to install a pressure gauge between the water supply pipe and the fire hydrant to detect the pressure between the water supply pipe, so as to judge whether the pressure in the pipe is sufficient. Referring to Chinese Patent Publication No. CN219558602U, a fire hydrant pressure detection device is provided, including a detection component, a display component and a linkage component; the detection component includes a pipe section, an inner pipe, an outer pipe and a first spring; the inner pipe, the outer pipe and the first spring are located in the pipe section, and the two ends of the outer pipe are an open end and a blocked end respectively; The outer end of the inner tube is fixed to the side wall of the tube segment, and the inner end of the inner tube slides in the outer tube from the open end, and a first spring is arranged between the outer tube and the inner tube to push the inner tube toward the open end; the display component includes a shell, a pointer and a rack, the shell is rotatably fitted with a rotating shaft, the outer end of the rotating shaft extends to the outside of the shell, the outer end of the rotating shaft is radially provided with the pointer, the shell is provided with a pressure scale corresponding to the pointer, the inner end of the rotating shaft is provided with a gear, a rack is slidably fitted in the shell, and the rack is meshed with the gear; the linkage component includes a wire tube and a linkage line, the two ends of the wire tube are respectively connected to the shell and the outer end of the inner tube, the linkage line is arranged in the wire tube, and the two ends of the linkage line are respectively connected to the rack and the outer tube. In this solution, the detection component is set on the water pipe underground or in the wall, and the display component is set on the ground or wall. The overall structure will not affect the existing fire hydrant structure, the modification cost is lower, and the water pressure can be detected in real time. However, when there is air pressure in the water supply pipe, it will affect the detection accuracy, and there may even be a situation where there is no water in the water supply pipe but the air pressure is normal.

The plug body 11 is connected to the water receiving channel 15, the valve seat 12 is arranged in the plug body 11, one end of the valve stem 13 is connected to the valve flap 14, and is used to drive the valve flap 14 to approach or move away from the valve seat 12, and the pressure relief valve 16 is arranged on one side of the plug body 11 and is located above the valve seat 12. The detection device 20 is arranged on one side of the fire hydrant body 10, and one end of the detection device 20 is connected to the water receiving channel 15, and the other end is connected to the plug body 11, and the valve seat 12 and the pressure relief valve 16 are located between the two connection points. In this embodiment, when inspection is required, the opening of the connection end between the detection device 20 and the water receiving channel 15 is opened. By observing the water flow in the detection device 20, it can be determined whether the water pressure and water flow in the water receiving channel 15 are normal. When the inspection is completed, the opening of the connection end between the detection device 20 and the bolt body 11 is opened, so that the water in the detection device 20 can flow out from the pressure relief valve 16 in the bolt body 11. During the inspection process, no water flows to the ground, which prevents water from splashing onto the inspectors or affecting the road. At the same time, the specific water flow in the detection device 20 can be observed to prevent the water receiving channel 15 from being filled with only gas, thereby preventing the traditional pressure gauge from making errors in inspections so that no water is available when the fire hydrant body 10 is really needed, thereby affecting the rescue progress.

[0022] Specifically, refer to Figure 1~Figure 2 As shown, the detection device 20 includes a water inlet pipe 21, a detection box 22 and a water outlet pipe 23.
