DETAILED DESCRIPTION

[0022] The embodiments of the present application will be described in detail below with the accompanying drawings and examples, so that the realization process of how to apply technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

[0023] As Figure 1 - Figure 5As shown, the fire hydrant with intelligent fire alarm function provided in this embodiment includes a fire hydrant box 1, an alarm component 7, and a triggering component 3. A fire hydrant box door 4 is installed on the front of the fire hydrant box 1. A push plate 5 is fixedly installed on the side of the fire hydrant box door 4 near the fire hydrant box 1. The triggering component 3 is fixed to the inner side of the fire hydrant box 1. The triggering component 3 includes a fixing block 301, a first spring 302, and a rotating plate 303. The fixing block 301 is fixedly connected to the inner side of the box. The first spring 302 is a torsion spring, and the rotating plate 303... One end of the rotating plate 302 is rotatably connected to the fixed block 301, and the other end of the spring 302 is fixedly connected to the rotating plate 303. A safety component 6 is fixedly connected to the side of the fire hydrant box 1. The safety component 6 is used to limit the rotation of the rotating plate 303. An alarm component 7 is provided on the top surface inside the fire hydrant box 1. A pressure sensor 8 is provided on one side of the alarm component 7. The pressure sensor 8 is electrically connected to the alarm component 7. A pressure block 9 is fixedly connected to one end of the rotating plate 303. The pressure sensor 8 is located on the positive side of the pressure block 9. Above, the push plate 5 is slidably connected to the upper surface of the rotating plate 303. The push plate 5 is an arc-shaped elastic sheet. The upper surface of the rotating plate 303 has a groove that matches the surface of the push plate 5. When the fire hydrant box is closed, the push plate 5 is stuck in the groove on the upper surface of the optional plate. At this time, the rotating plate 303 is restricted by the push plate 5 and cannot rotate, and does not contact the pressure sensor 8. When the fire hydrant box is opened, the rotating plate 303 rotates under the elastic force of the first spring 302, which then causes the pressure block 9 to trigger the pressure sensor. When the fire hydrant box door 4 is closed, the push plate 5... The rotating plate 303 slides against the upper surface of the rotating plate 303, causing the rotating plate 303 to drive the pressure block 9 to disengage from the pressure sensor 8. When the pressure block 9 triggers the pressure sensor 8, the alarm component 7 is triggered synchronously. When the pressure block 9 disengages from the pressure sensor 8, the alarm component 7 de-alarms. When operated by personnel, the personnel insert the key into the safety component 6 to restrict the rotation of the rotating plate 303. When the fire hydrant box door 4 is opened, the alarm component 7 does not alarm, thus allowing the personnel to inspect the fire hydrant.

[0024] Furthermore, such as Figure 4 As shown, the alarm assembly 7 includes a siren 701, a battery 702, a transmitter 703, a controller 704, and a housing 705. The housing 705 is fixedly connected to the top surface inside the fire hydrant box 1. The siren 701, battery 702, transmitter 703, and controller 704 are all fixed inside the housing 705. The siren 701 and transmitter 703 are electrically connected to the controller 704. When the pressure sensor 8 is pressurized, it transmits an electrical signal to the controller 704. The controller 704 controls the siren 701 to sound an alarm and then sends the information through the transmitter 703. The battery 702 serves as a backup power source for the controller 704, the siren 701, and the transmitter 703.

[0025] Wherein, as shown in Figure 3 The safety assembly 6 includes a lock head 601 and a cam 602. The fire hydrant box body 1 is provided with a lock hole 10 near the side close to the trigger assembly 3. The lock head 601 is installed in the lock hole 10. The cam 602 is fixedly connected to the inner side of the lock head 601. The side surface of the rotating plate 303 is provided with a limiting hole 11. The cam 602 is inserted into the limiting hole 11. The key is inserted into the lock hole 10 to twist the lock head 601, so that the cam 602 rotates. When the cam 602 is transversely rotated, the rotating plate 303 can be turned to the top to trigger the pressure sensor. When the protruding part of the cam 602 is downward, the rotating plate 303 is limited to rotate by the cam 602, so that the rotating plate 303 cannot contact the pressure sensor, thereby causing the alarm assembly 7 to be unable to trigger. The lock head 601 only locks the cam 602 and does not lock the fire hydrant door.

[0026] Wherein, as shown in Figure 1 And Figure 5 The lower bottom surface of the fire hydrant box body 1 is provided with a rotating water head 12. The fire hydrant is an ultra-thin box body. The outer side of the fire hydrant door is provided with an embedded handle 13. The rotating water head 12 can be rotated to the front surface in use and rotated to the side surface in non-use. The ultra-thin box body and the embedded door handle make the fire hydrant occupy less space in the corridor or stairwell.

[0027] As shown in Figure 1 - Figure 5 The principle of the fire hydrant with intelligent fire alarm function provided by the embodiment is as follows: when the fire hydrant box is in the closed state, the push plate 5 is clamped in the groove on the upper surface of the optional plate. At this time, the rotating plate 303 is limited to rotate by the push plate 5 and cannot contact the pressure sensor 8. When the fire hydrant box is opened, the rotating plate 303 is rotated under the elastic force of the first spring 302, and then the pressing block 9 triggers the pressure sensor. When the fire hydrant box door 4 is closed, the push plate 5 abuts against and slides on the upper surface of the rotating plate 303, so that the rotating plate 303 drives the pressing block 9 to be separated from the pressure sensor 8. When the pressing block 9 triggers the pressure sensor 8, the alarm assembly 7 is synchronously triggered. When the pressing block 9 is separated from the pressure sensor 8, the alarm assembly 7 is released from the alarm. When operated by the staff, the staff inserts the key into the safety assembly 6, so that the safety assembly 6 limits the rotation of the rotating plate 303. When the fire hydrant box door 4 is opened, the alarm assembly 7 does not alarm, thereby enabling the staff to maintain the fire hydrant. When the fire hydrant is operated by the staff, the alarm assembly 7 is not alarmed by operating the safety assembly 6, thereby facilitating the staff to maintain the fire hydrant. When a fire occurs, the fire hydrant box can still be opened by the nearby crowd to extinguish the fire in time. When the fire hydrant box is opened by the non-staff, the pressing block 9 triggers the pressure sensor, thereby causing the alarm assembly 7 to issue an alarm. At the same time, the information of opening and closing is issued, which is checked by the staff in time to avoid the misuse and damage of the fire-fighting facilities.

[0028] Certain terminology can also be used in the summary or detailed description of the present application for the purpose of brevity but are intended to be in no way limiting of the application. For example, the terms "right," "left," "rear," "front," "up," "down," "under" and the like as can be referenced herein can mean such terms only in the context of the particular view being referred to and can not necessarily be intended to refer to similar terms in other drawings.

[0029] It should be noted that, as used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise. Thus, for example, reference to "a component" can include a combination of two or more components, and the term "an element" can mean a combination of two or more elements.

[0030] The above specification and examples provide a complete description of the application. Since they fully disclose the application, they describe and define it sufficiently to communicate a practical, useful, and industrial application of the application to others skilled in the art. Many modifications and variations of the application can be possible in light of the above teachings without departing from the spirit and scope of the application, which is defined by the claims.
