[0002] A fire hydrant water pressure detection device is a device installed in a fire hydrant system to monitor and measure the water pressure in the fire hydrant system. It can monitor the water pressure in the fire hydrant system in real time to ensure that the system can provide sufficient water pressure when needed to respond to fires and other emergencies. This device usually alerts firefighters or system operators to ensure that they can take appropriate measures to maintain the system and ensure its normal operation.

[0003] The water pressure detection device of the fire hydrant in the prior art usually directly detects the water pressure in the fire hydrant through a water pressure detector. During the detection, the probe of the detector needs to be in direct contact with the water in the fire hydrant. There are many hard impurities in the water in the fire hydrant. When the probe is in contact with water for a long time, the hard impurities may collide with the probe, causing damage to the probe, affecting the water pressure detection, and causing economic losses.

[0004] To this end, we provide a water pressure detection device for a fire hydrant to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0030] See also Figure 1-5 The utility model is a water pressure detection device for a fire hydrant, comprising a fire hydrant body 1, and a detection cylinder 2 is connected to the top of one side of the fire hydrant body 1;

[0031] The inner cavity of the detection tube 2 is provided with a detection assembly, which includes a moving plate 3, which is slidably connected to one side of the inner cavity of the detection tube 2, a collision rod 4 is fixedly connected to one side of the moving plate 3, and a contact plate 5 is slidably connected to the inner cavity of the detection tube 2, and a buffer is provided on one side of the contact plate 5;

[0032] The inner cavity of the detection tube 2 is provided with a protection component, which includes a collision sensor 6 . The collision sensor 6 is fixed to the top and bottom of one side of the inner cavity of the detection tube 2 . An alarm 7 is fixedly connected to one side of the surface of the detection tube 2 .

[0033] Specifically: one end of the inner cavity of the detection cylinder 2 is connected to the top of one side of the inner cavity of the fire hydrant, and the other end is in a closed state. The movable disk 3 is located on the right side of the inner cavity of the detection cylinder 2, the contact disk 5 is located in the center, and the buffer disk 9 is located on the left side of the detection cylinder 2. When one side of the contact disk 5 contacts one end of the collision rod 4, the movable disk 3 will be driven to move. In the initial state, there is a certain gap between one end of the collision rod 4 and one side of the contact disk 5 to prevent the water flow from driving the movable disk 3 to move at the moment of spraying, thereby affecting the water pressure detection result. The alarm 7 can sound an alarm when the air pressure display state in the controller 10 is higher than the set value. Specific embodiment 2

[0035] See also Figure 1-5 On the basis of the specific embodiment 1, the buffer member includes a telescopic rod 8, the telescopic rod 8 is fixed to one side of the contact plate 5, one end of the telescopic rod 8 is fixedly connected to the buffer plate 9, one end of the detection tube 2 is fixedly connected to the controller 10, one side of the inner cavity of the detection tube 2 is fixedly connected to the air pressure detector 11, the output end of the air pressure detector 11 is unidirectionally electrically connected to the input end of the controller 10, one side of the surface of the detection tube 2 is connected to a water outlet pipe 12, one side of the surface of the water outlet pipe 12 is sleeved with a valve 13, and the bottom end of the water outlet pipe 12 is fixedly connected to a flange 14.

[0036] Specifically: one end of the telescopic rod 8 is fixed to one side of the contact plate 5, and the other end is fixed to one side of the buffer plate 9, so as to produce a certain buffering effect on the movement of the contact plate 5. The controller 10 can detect the air pressure state in the detection tube 2 through the air pressure detector 11, so as to detect the water pressure of the fire hydrant, and display the air pressure state through the air pressure detector 11, and control the electric control valve 16 through the air pressure display. The water outlet pipe 12 is located at the bottom left side of the surface of the detection tube 2. The flange 14 at the bottom can be connected to the nozzle or the joint of the connecting pipe to facilitate water spraying. When not detecting, the electric control valve 16 is controlled to release the internal air pressure to reset the buffer plate 9, the movable plate 3 and the contact plate 5. Specific embodiment three

[0038] See also Figure 1-5On the basis of the specific embodiment 1 and the specific embodiment 2, an air outlet pipe 15 is connected to the bottom of one end of the detection cylinder 2, and an electric control valve 16 is sleeved on the surface of the air outlet pipe 15. The input end of the electric control valve 16 is unidirectionally electrically connected to the output end of the controller 10. A sealing ring 17 is fixedly connected to the surface of the buffer disk 9, and the surface of the sealing ring 17 is in contact with the inner cavity of the detection cylinder 2. A spring 18 is sleeved on one side of the surface of the telescopic rod 8. The number of the telescopic rods 8 is four. One end of the spring 18 is fixed to one side of the buffer disk 9. A fixed base 19 is fixedly connected to the bottom of the fire hydrant body 1. The inner cavity of the fixed base 19 is provided with mounting holes, and the number of the mounting holes is six.

[0039] Specifically: the air outlet pipe 15 makes the air pressure on one side of the detection tube 2 with the air pressure detector 11 equal to the external air pressure in the initial state to avoid affecting the detection, and during the detection, the air outlet pipe 15 can be sealed by the electric control valve 16 to increase the internal air pressure to facilitate the measurement of the air pressure state. After the internal air pressure reaches the set value, the electric control valve 16 can be automatically opened to release the internal air pressure to avoid damage to the detection device. The sealing ring 17 prevents water from entering the rear half of the detection tube 2 during impact and ensures that the internal air pressure will not leak. The spring 18 allows the buffer disk 9 to automatically reset.

[0040] The working principle of the utility model is as follows: when it is necessary to detect the water pressure of the fire hydrant, firstly, the electric control valve 16 is closed by controlling the controller 10, and the air pressure inside the detection tube 2 is consistent with the external atmospheric pressure, then the water in the fire hydrant is passed into the detection tube 2, and the moment the water flows into the detection tube 2, it impacts the buffer plate 9, and the impact force of the water flow is buffered by the telescopic rod 8 and the spring 18, and then when the water pressure of the water flow is basically stable, it will push the moving plate 3 and the contact plate 5 to move, so that one side of the contact plate 5 contacts one end of the collision rod 4, and push the moving plate 3 to move, so that the gas in the rear section of the moving plate 3 and the inner cavity of the detection tube 2 is compressed, and when the water pressure is stable, the moving plate 3 no longer moves, and the air pressure inside the detection tube 2 is detected by the air pressure detector 11, so that the water pressure can be judged by the air pressure, and the water flow and the external nozzle are passed by controlling the valve on the water outlet pipe;

[0041] When the water pressure is too high, the movable disk 3 will contact the collision sensor 6, and the collision sensor 6 will convert the collision signal into an electrical signal and transmit it to the controller 10. The controller 10 controls the alarm 7 to sound an alarm to remind the user, and the controller 10 can open the electric control valve 16 to release the air pressure inside the detection tube 2 to prevent the air pressure inside the detection tube 2 from being too high and damaging the detection equipment.
