Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a fire hydrant with an alarm function. Background Art

[0002] Outdoor fire hydrants are water supply facilities installed on the fire 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 water supply network to extinguish fires. They can also be directly connected to water hoses and water guns to discharge water for fire extinguishing. Therefore, the outdoor fire hydrant system is also one of the important fire fighting facilities for fire fighting.

[0003] Existing outdoor fire hydrants will age due to long-term exposure to sunlight and rain. The aging of the rubber sealing ring will cause the seal to fail, resulting in water leakage. If the relevant personnel cannot be informed in time, it will cause a waste of water resources. Based on this, we propose an improved fire hydrant with an alarm function. Utility Model Content

[0004] The main purpose of the utility model is to provide a fire hydrant with an alarm function, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A fire hydrant with an alarm function comprises a valve body, a wireless alarm and a foam board, and is characterized in that: a guide cylinder is fixedly sleeved on the valve body, a mounting seat is fixedly sleeved in the guide cylinder near the upper end, the wireless alarm is fixedly connected to the upper end of the mounting seat, a pressure sensor is fixedly connected to the middle of the lower end of the mounting seat, and the foam board is arranged directly below the pressure sensor.

[0007] As a further solution of the present utility model, the pressure sensor includes a communication module, an alarm module and a controller module, and the pressure sensor is electrically connected to the controller module.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a fire hydrant with an alarm function includes a valve body 1, a wireless alarm 9 and a foam board 12, and is characterized in that: a guide cylinder 7 is fixedly sleeved on the valve body 1, a mounting seat 8 is fixedly sleeved in the guide cylinder 7 near the upper end, the wireless alarm 9 is fixedly connected to the upper end of the mounting seat 8, a pressure sensor 10 is fixedly connected to the middle of the lower end of the mounting seat 8, and the foam board 12 is arranged directly below the pressure sensor 10.

[0023] In this embodiment, the pressure sensor 10 includes a communication module, an alarm module and a controller module. The pressure sensor 10 is electrically connected to the controller module. The communication module is used to send alarm signals to terminals such as mobile phones and computers, and the alarm module is used to control the flashing of the alarm light.

[0024] In this embodiment, a pressing sheet 17 is fixedly connected to the upper end of the foam board 12, and a foam column 13 is fixedly connected to the lower end of the foam board 12. The weight of the pressing sheet 17 is less than that of the foam column 13, so as to avoid the foam board 12 being unable to rise due to buoyancy due to the pressing sheet 17 being too heavy.

[0025] In this embodiment, sliding rods 11 are fixedly connected to both sides of the lower end surface of the mounting seat 8. A circular plate is fixedly sleeved on the lower end of the sliding rod 11 to limit the maximum downward movement distance of the foam board 12. The foam board 12 is slidably sleeved on the outer wall of the sliding rod 11, and the sliding rod 11 is used to limit and guide the movement of the foam board 12.

[0026] In this embodiment, a valve stem 2 is threadedly sleeved on the valve body 1, the upper end of the valve stem 2 passes through the valve body 1 and is fixedly sleeved with a handwheel 3, the lower end of the valve stem 2 is fixedly sleeved with a valve plate 4, a plug 5 is threadedly sleeved at one end of the valve body 1, and a hanging chain 6 is fixedly connected between the outer walls of the valve body 1 and the plug 5.

[0027] In this embodiment, a protective cover 14 is sleeved on the outer end of the mounting base 8 . The protective cover 14 is made of a transparent material, and the wireless alarm 9 is protected by the protective cover 14 .

[0028] In this embodiment, a clamping plate 15 is fixedly connected to the upper end of the protective cover 14, and a locking plate 16 is rotatably connected to the outer wall of the valve body 1. The locking plate 16 and the clamping plate 15 are engaged with each other. The protective cover 14 can be fixed on the mounting seat 8 by sleeve-connecting the locking plate 16 with the clamping plate 15, and quick and convenient disassembly is also possible. The sliding friction between the locking plate 16 and the clamping plate 15 is greater than the weight of the locking plate 16 itself, thereby preventing the locking plate 16 from easily sliding out of the clamping plate 15.

[0029] It should be noted that the utility model is a fire hydrant with an alarm function. When in use, the plug 5 is opened to connect the water gun, and then the valve stem 2 is driven to rotate by the hand wheel 3 to drive the valve plate 4 to rise, and the valve body 1 is opened to supply water to the water gun for fire extinguishing. When the device is not in use, the sealing ring ages with time, leakage occurs at the valve plate 4, and the liquid gradually fills the inside of the valve body 1. At this time, as the liquid increases, the foam column 13 will drive the foam plate 12 to rise, and then under the guidance of the slide rod 11, the pressing piece 17 will eventually press against the pressure sensor 10, and then convert the pressure signal into an electrical signal and send it to the wireless alarm 9 to alarm and remind relevant personnel to repair the device.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
