Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, and in particular to a tamper-proof alarm structure and an intelligent fire hydrant. Background Technology

[0002] Outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings. They are mainly used by fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network for fire fighting. They can also be directly connected to fire hoses and nozzles to extinguish fires. They are one of the important fire-fighting facilities for fighting fires.

[0003] Existing fire hydrants are generally installed above ground level, making them susceptible to impacts from vehicles and other objects, which can cause deformation or even breakage. This can easily lead to the spraying of fire water, wasting water resources and damaging surrounding property. Furthermore, existing fire hydrants lack active alarm structures, making it difficult for fire departments to obtain accurate information about hydrant damage in a timely manner, resulting in untimely repairs. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a tamper-proof alarm structure and an intelligent fire extinguishing and water supply hydrant.

[0005] The technical solution of this utility model is as follows: On the one hand, this utility model proposes an anti-vandalism alarm structure, including a host, a controller installed inside the host, and the controller being electrically connected to a tilt sensor and a warning light;

[0006] A protective cover with a cylindrical cavity inside, and a conductive ring coaxial with the arc-shaped inner wall of the cylindrical cavity.

[0007] The cylindrical cavity has a conductive metal ball, and a vertically downward cable is installed on the upper wall of the cavity. The conductive metal ball is connected to the lower end of the cable, and the main unit is powered on after the conductive metal ball comes into contact with the conductive ring.

[0008] Preferably, a wireless signal transmitter is installed inside the host, and the wireless signal transmitter is electrically connected to the controller.

[0009] Preferably, the host computer is equipped with a GPS module for auxiliary positioning.

[0010] On the other hand, this utility model also proposes an intelligent fire hydrant using the above-mentioned anti-vandalism alarm structure, including a ground stake, a sub-control valve, a fire hydrant, and a drive assembly. A water inlet pipe communicating with the interior of the ground stake is installed on the ground stake. The sub-control valve is installed inside the ground stake. The fire hydrant is connected to the ground stake and communicates with its output end. A water outlet pipe communicating with the interior of the fire hydrant is installed on the fire hydrant. A detachable sealing cap is installed at the opening of the water outlet pipe. The main unit, tilt sensor, and warning light are all connected to the fire hydrant. A protective cover is movably installed inside the fire hydrant. The drive assembly is installed on the fire hydrant and drives the protective cover. When the protective cover moves downwards, it gradually opens the sub-control valve, and when the protective cover moves upwards, it closes the sub-control valve.

[0011] Preferably, a main control valve is installed on the water inlet pipe to control the on / off state of its internal components.

[0012] Preferably, the control valve includes an annular valve seat, a valve cover, and a float. The annular valve seat is disposed inside the ground pile and between its input and output ends. A telescopic rod is disposed below the annular valve seat inside the ground pile. The valve cover is connected to the movable end of the telescopic rod and is coaxial with the annular valve seat. The float is connected to the end of the valve cover away from the telescopic rod, and the outer diameter of the float is not greater than the inner diameter of the channel of the annular valve seat.

[0013] Preferably, the drive assembly includes a slide rod and a lead screw. A waterproof pipe is vertically installed downward on the upper wall of the inner cavity of the fire hydrant. A positioning block is installed inside the lower opening of the waterproof pipe. A sliding channel is provided between the side of the positioning block and the inner wall of the waterproof pipe. A slider is installed inside the waterproof pipe and slides along its axis. The upper end of the slide rod is inserted into the waterproof pipe along the sliding channel and connected to the slider. A protective cover is connected to the lower end of the slide rod. The main body of the lead screw is located inside the waterproof pipe. The lower end of the lead screw is rotatably connected to the positioning block. The upper end of the lead screw extends out of the fire hydrant and is rotatably connected to it. The lead screw passes through the slider and is helically connected to it. An anti-theft end is provided at the end of the lead screw away from the positioning block.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] By incorporating warning lights, a wireless signal transmitter, and a GPS module, the warning lights illuminate at night, forming a marker light structure on the fire hydrant to help alert oncoming vehicles to avoid it. The warning lights also flash frequently in response to impacts, while the wireless signal transmitter, in conjunction with the GPS module, promptly sends alarm information and location data to professionals when the fire hydrant is damaged. A oscillating conductive metal ball and a conductive ring surrounding it automatically trigger the main unit when the ball collides with the ring upon impact. This design allows the main unit to remain in standby mode under normal conditions, saving energy and extending its lifespan. Furthermore, ground stakes house a sub-control valve consisting of a ring valve seat, valve cover, telescopic rod, and float. A drive assembly inside the fire hydrant operates this sub-control valve, preventing a sudden gush of fire water even after the hydrant is damaged. Attached Figure Description

[0023] Example 1

[0024] like Figure 5 and Figure 6As shown, this utility model proposes an anti-vandalism alarm structure, including a main unit 1, a protective cover 4, and a conductive metal ball 7. The main unit 1 houses a controller, which is a PLC controller electrically connected to a tilt sensor 2 and an alarm light 3. A light sensor electrically connected to the controller is mounted on the main unit 1. A flashing relay controlling the flashing frequency of the alarm light 3 is also installed within the main unit 1. A wireless signal transmitter is installed within the main unit 1, electrically connected to the controller and communicating with a professional's terminal equipment. A GPS module for auxiliary positioning is also installed within the main unit 1. A cylindrical cavity is formed within the protective cover 4, with a conductive ring 5 coaxially mounted on its arc-shaped inner wall. A vertically downward cable 6, a flexible cable, is mounted on the upper wall of the cylindrical cavity at its center. The conductive metal ball 7 is connected to the lower end of the cable 6. The cable 6 and the conductive ring 5 are connected to the corresponding ends of a delay switch on the main unit 1, and the main unit 1 is energized when the conductive metal ball 7 contacts the conductive ring 5.

[0025] In this embodiment, the structure is installed on the object under test and connected to mains power. The warning light 3 flashes at a low frequency at night to provide a contour reminder of the object under test. The warning light 3 does not flash during the day, saving energy. The protective cover 4 is installed with its axis in a vertical position. In this state, the conductive metal ball 7 and the conductive ring 5 do not contact each other. When the protective cover 4 is tilted, the conductive metal ball 7 swings and contacts the conductive ring 5, causing the delay switch to close, thereby activating the host 1. The host 1 activates and controls the wireless signal transmitter to send signals to the professional's terminal device (such as a mobile phone) in real time. At this time, the warning light 3 flashes at a high frequency to warn the surrounding crowd. At the same time, the tilt sensor 2 is activated and detects the tilt state of the object under test. If the object under test is tilted after being hit, the wireless signal transmitter sends the tilt angle of the object under test to the professional. If the tilt angle is within a reasonable range, the warning light 3 returns to its original state.

[0026] Example 2

[0027] like Figures 1-6As shown, the intelligent fire hydrant of this utility model, which adopts the anti-vandalism alarm structure described in Embodiment 1, further includes a ground stake 8, a sub-control valve, a fire hydrant 16, and a drive assembly. A water inlet pipe 9 communicating with the interior of the ground stake 8 is provided on the ground stake 8. A main control valve 10 controlling the on / off state of the water inlet pipe 9 is provided on the water inlet pipe 9. The main control valve 10 includes, but is not limited to, a butterfly valve. The sub-control valve is located inside the ground stake 8 and includes an annular valve seat 12, a valve cover 14, and a float 15. The annular valve seat 12 is located inside the ground stake 8 and at its input end... Between the output ends, an annular plate 11 is installed inside the ground pile 8. Several studs are arranged in a circular array around the axis of the annular plate 11. The annular valve seat 12 rests on the annular plate 11 and is connected to the annular plate 11 by nuts and studs. A telescopic rod 13 is installed inside the ground pile 8 below the annular valve seat 12. The valve cover 14 is connected to the movable end of the telescopic rod 13 and is coaxial with the annular valve seat 12. The float ball 15 is connected to the end of the valve cover 14 away from the telescopic rod 13, and the outer diameter of the float ball 15 is not greater than the inner diameter of the channel of the annular valve seat 12. Fire hydrant 16 is connected to ground stake 8 and communicates with the output end of ground stake 8. Fire hydrant 16 is provided with water outlet pipe 17 communicating with its interior. A sealing cover is detachably installed at the opening of water outlet pipe 17. Main unit 1, tilt sensor 2 and warning light 3 are all connected to fire hydrant 16. Protective cover 4 is movably installed inside fire hydrant 16. Drive component is installed on fire hydrant 16 and drives protective cover 4. Protective cover 4 gradually opens the sub-control valve when it moves down and closes the sub-control valve when it moves up. The drive assembly includes a slide rod 19 and a lead screw 20. A waterproof pipe 18 is vertically installed downwards on the upper wall of the inner cavity of the fire hydrant 16. A positioning block is installed inside the lower opening of the waterproof pipe 18. A sliding channel is provided between the side of the positioning block and the inner wall of the waterproof pipe 18. A slider is installed inside the waterproof pipe 18 and slides along its axis. The upper end of the slide rod 19 is inserted into the waterproof pipe 18 along the sliding channel and connected to the slider. A protective cover 4 is connected to the lower end of the slide rod 19. A top rod 41 is installed at the lower end of the protective cover 4, and the top rod 41 is located directly above the float 15. The main body of the lead screw 20 is located inside the waterproof pipe 18. The lower end of the lead screw 20 is rotatably connected to the positioning block. The upper end of the lead screw 20 extends out of the fire hydrant 16 and is rotatably connected to it. The lead screw 20 passes through the slider and is helically connected to it. An anti-theft end is provided at the end of the lead screw 20 away from the positioning block. The anti-theft end is, but is not limited to, a stylized cap with a column.

[0028] In this embodiment, during actual use, the fire hydrant 16 is connected to the ground stake 8, and the ground stake 8 is buried underground. The main control valve 10 is kept in the normally open state (when it is necessary to replace the annular valve seat 12 or the valve cover 14, the main control valve can be closed). Since the water inlet pipe 9 is directly connected to the fire pipeline, the ground stake will be filled with water. At this time, the float will be pushed up and drive the valve cover 14 to move upward. Under the pressure of the water below, the valve cover 14 will maintain a sealed fit with the annular valve seat 12. When water needs to be taken, the sealing cover is opened and the fire pipeline end is connected to the water outlet pipe 17. The anti-theft end is driven to rotate with the help of a special tool, thereby driving the screw 20 to rotate. The screw 20 drives the slider to slide and presses down the protective cover 4 and the top rod 41 through the sliding slide rod 19. The top rod 41 presses down the float 15 until the valve cover 14 opens and the water rises and enters the fire pipeline along the water outlet pipe 17 under high pressure. When the water usage ends, the protective cover 4 is driven to slide up and reset and the sealing cover is closed. When the fire hydrant 16 is impacted and tilted, the float ball 15 remains sealed to the annular valve seat 12, preventing water jetting. Upon impact, the conductive metal ball 7 swings and contacts the conductive ring 5, triggering the main unit 1 to enter an alarm state. At this time, the warning light 3 flashes at high frequency, and the wireless signal transmitter sends the impact information of the fire hydrant 16 to the terminal equipment of professionals. Simultaneously, the tilt sensor 4 detects the state of the impacted fire hydrant 16. If its tilt is within a safe range, the warning light 3 returns to its original state, and the tilt angle and direction information of the fire hydrant 16 are transmitted back to the terminal equipment. The main unit 1 then returns to standby mode, achieving energy saving.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
