Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fire protection equipment technology, specifically a mechanical fire hydrant water pressure abnormality warning device. Background Technology
[0002] Firefighting equipment is an important infrastructure for ensuring public safety and preventing and extinguishing fires. It comes in many types and has different functions. Among them, fire hydrant water pressure warning is an important measure to ensure the normal operation of fire water systems and improve fire prevention and control capabilities.
[0003] The existing fire hydrant water pressure early warning system can monitor the fire water pressure in real time to ensure that the water pressure meets the standard requirements. When the water pressure is lower or higher than the set threshold, the system will immediately issue an alarm to notify relevant personnel to handle the situation. Overall, the system predicts potential fire safety hazards through data analysis and reduces fire extinguishing delays caused by insufficient water pressure.
[0004] Currently, mechanical devices rely on flags or pointers, resulting in low visibility in low light conditions. Additionally, some illuminated devices use pressure sensors in conjunction with circuit control, which makes overall installation difficult and leads to low visibility when water pressure is abnormal, thus requiring improved inspection efficiency.
[0005] Therefore, a mechanical fire hydrant water pressure abnormality warning device is proposed to address the above problems. Utility Model Content

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A mechanical fire hydrant water pressure abnormality warning device of this utility model includes a warning device housing; a siphon tube is connected to one side of the warning device housing; a support column is fixedly connected between the top and bottom of the inner wall of the warning device housing; a piston plate is slidably connected to the surface of the support column; a return spring is sleeved on the surface of the support column; the two ends of the return spring are fixedly connected to the top of the inner wall of the warning device housing and the top of the piston plate, respectively; sliding insulating light rods are fixedly connected to both sides of the top of the piston plate; a trigger conductive block is fixedly connected to the top of the sliding insulating light rod; an insulating sealing block is fixedly connected to the top of the trigger conductive block; conductive plug blocks adapted to the trigger conductive blocks are fixedly connected to both sides of the top of the warning device housing; a conductive wire is fixedly connected to the surface of the conductive plug block; and a warning light is fixedly connected to the top of the warning device housing, with the surface of the warning light communicating with the conductive wire.
[0008] Preferably, a battery box is fixedly connected to the top of the alarm housing on the side away from the siphon tube, and a storage battery is fixedly connected inside the battery box, with the top of the storage battery connected to a conductive wire.
[0009] Preferably, the number of sliding insulating light rods is set to two, and the top ends of both sliding insulating light rods penetrate through the alarm housing and extend to the top of the alarm housing. The two sliding insulating light rods are fixedly connected to the bottom of the trigger conductive block at the top of the alarm housing.
[0010] Preferably, a connecting base is fixedly connected to the bottom of the alarm housing, and a transparent scale is provided on the surface of the alarm housing and on the side of the siphon tube.
[0011] Preferably, a square frame is fixedly connected to the inner wall of the alarm housing, and the square frame is set higher than the height of the siphon tube.
[0012] Preferably, a discharge port is provided at the bottom of one side of the warning device housing.

When water enters the warning device housing via a piston plate, the water causes the piston plate to rise. When the water pressure exceeds a threshold, the piston plate moves upward, causing the sliding insulating rod and trigger conductive block to move away from the conductive plug, disconnecting the circuit and extinguishing the warning light. When the water pressure falls below the threshold, a reset spring causes the piston plate to move downward, triggering the conductive block to move into the conductive plug, reconnecting the circuit and illuminating the warning light. The overall structure is simple, installation is easy, and thus improves inspection efficiency.
[0015] This utility model provides a mechanical fire hydrant water pressure abnormality warning device. By setting an electric telescopic rod and a sealing plate, the water inside the warning device housing can be quickly discharged, making it convenient to keep the warning device housing for backup or maintenance, thereby improving its adaptability.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figures 1-5This utility model provides a mechanical fire hydrant water pressure abnormality warning device, including a warning device housing 1; a siphon tube 2 is connected to one side of the warning device housing 1; a support column 3 is fixedly connected between the top and bottom of the inner wall of the warning device housing 1; a piston plate 4 is slidably connected to the surface of the support column 3; a return spring 5 is sleeved on the surface of the support column 3; the two ends of the return spring 5 are fixedly connected to the top of the inner wall of the warning device housing 1 and the top of the piston plate 4, respectively; sliding insulating light rods 6 are fixedly connected to both sides of the top of the piston plate 4; a trigger conductive block 7 is fixedly connected to the top of the sliding insulating light rod 6; an insulating sealing block 8 is fixedly connected to the top of the trigger conductive block 7; conductive plug blocks 9 adapted to the trigger conductive block 7 are fixedly connected to both sides of the top of the warning device housing 1; and conductive wires 10 are fixedly connected to the surface of the conductive plug blocks 9. The top of the warning device housing 1 is fixedly connected to a warning light 11, and the surface of the warning light 11 is connected to the conductive wire 10. During operation, the siphon tube 2 is set at the bottom of one side of the warning device housing 1. Using the siphon principle, water is drawn into the warning device housing 1. When the amount of water entering is less than the threshold, the piston plate 4 will not move upward. When the water pressure is greater than the threshold, the piston plate 4 moves upward, thereby driving the sliding insulating light rod 6 and the trigger conductive block 7 away from the conductive plug block 9. The circuit is disconnected and the warning light 11 is extinguished. When the water pressure is less than the threshold, the reset spring 5 drives the piston plate 4 downward, and the trigger conductive block 7 moves into the conductive plug block 9. The circuit is connected, and the warning light 11 lights up. The conductive wire 10 is used to clear the circuit. The insulating sealing block 8 supports and protects the trigger conductive block 7 at the bottom and does not conduct electricity. The overall structure is simple and easy to install, thereby improving the efficiency of inspection.
[0027] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, a battery box 12 is fixedly connected to the top of the alarm housing 1 on the side away from the siphon tube 2. A storage battery 13 is fixedly connected inside the battery box 12, and the top of the storage battery 13 is connected to the conductive wire 10. Two sliding insulating rods 6 are provided, and the top ends of both sliding insulating rods 6 penetrate the alarm housing 1 and extend to the top of the alarm housing 1. One end of each sliding insulating rod 6 located at the top of the alarm housing 1 is fixedly connected to the bottom of the trigger conductive block 7. During operation, the alarm housing 1 supports and fixes the battery box 12. The inside of the battery box 12 is used to protect and support the storage battery 13, which provides power. The two sliding insulating rods 6 support the two trigger conductive blocks 7. Using two sliding insulating rods 6 and trigger conductive blocks 7, compared to using a single rod, ensures the stability of both sides of the piston plate 4 during movement and prevents lateral deviation.
[0028] Furthermore, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a connecting base 14 is fixedly connected to the bottom of the alarm housing 1, and a transparent scale 15 is provided on the surface of the alarm housing 1 and on one side of the siphon tube 2; a square frame 16 is fixedly connected to the inner wall of the alarm housing 1, and the square frame 16 is set higher than the height of the siphon tube 2; a discharge port 17 is opened at the bottom of one side of the alarm housing 1, a sealing plate 18 is slidably connected inside the discharge port 17, a sliding support rod 19 is slidably connected to the surface of the sealing plate 18, the two ends of the sliding support rod 19 are fixedly connected to the inner wall of the discharge port 17, and an electric telescopic rod 20 is fixedly connected to the top of the sealing plate 18, and the top of the electric telescopic rod 20 is fixedly connected to the top of the inner wall of the discharge port 17. During operation, the connecting base 14 is fixed to the bottom of the alarm housing 1 for connection to the ground or wall. The transparent scale 15 allows for real-time monitoring of the water level inside the alarm housing 1. The square frame 16 is fixed inside the alarm housing 1, with its height slightly higher than the height of the siphon tube 2 inside the alarm housing 1. This height is also set as the threshold critical point. The discharge port 17 is used for drainage. After the electric telescopic rod 20 is in operation, it can drive the sealing plate 18 to rise and fall along the sliding support rod 19, thereby controlling the discharge port 17 to be blocked, and thus quickly draining the water inside the alarm housing 1. This allows the alarm housing 1 to be easily kept on standby or repaired, thereby improving its adaptability.
[0029] Working principle: First, the siphon tube 2 is set at the bottom of one side of the alarm housing 1. Using the siphon principle, water is drawn into the alarm housing 1. When the amount of water entering is less than the threshold, the piston plate 4 will not move upward. When the water pressure is greater than the threshold, the piston plate 4 moves upward, thereby driving the sliding insulating light rod 6 and the trigger conductive block 7 away from the conductive plug block 9. The circuit is broken and the alarm light 11 is turned off. When the water pressure is less than the threshold, the reset spring 5 drives the piston plate 4 downward, and the trigger conductive block 7 moves into the conductive plug block 9. The circuit is connected and the alarm light 11 lights up. The conductive wire 10 is used to clear the circuit. The insulating sealing block 8 supports and protects the trigger conductive block 7 at the bottom and does not conduct electricity. The overall structure is simple and easy to install, thereby improving the efficiency of inspection. In addition, the alarm housing 1 supports and fixes the battery box 12. The battery box 12 is used to protect and support the storage battery 13, which provides power. Two sliding insulating light rods 6 are set to support two trigger conductive blocks 7. The use of two sliding insulating light rods 6 and trigger conductive blocks 7, compared to a single rod, can ensure the stability of both sides when the piston plate 4 moves, preventing lateral deviation. Finally, the connecting base 14 is fixed to the bottom of the alarm housing 1 for connection to the ground or wall. The transparent scale 15 allows for real-time monitoring of the water level inside the alarm housing 1. The square frame 16 is fixed inside the alarm housing 1, and its height is slightly higher than the height of the siphon tube 2 inside the alarm housing 1. This height is also set as the threshold critical point. The discharge port 17 is used for drainage. After the electric telescopic rod 20 is activated, it can drive the sealing plate 18 to rise and fall along the sliding support rod 19, thereby controlling the discharge port 17 to block it and quickly draining the water inside the alarm housing 1. This allows the alarm housing 1 to be easily kept on standby or repaired, thus improving its adaptability.
