Description

Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to a fault diagnosis device for an automatic sprinkler fire-extinguishing system of a building. Background Art

[0002] The building automatic sprinkler fire extinguishing system is a highly efficient automatic fire extinguishing system that is widely used in various types of buildings for preventing and controlling fires. The system can automatically start at the early stage of a fire, quickly spray water to extinguish the fire, effectively reduce fire losses, and ensure personnel safety. In order to ensure that the system can be detected by management personnel in a timely manner when a failure occurs, the system fault diagnosis device can be used to alarm. The building automatic sprinkler fire extinguishing system fault diagnosis activates the alarm device through the flow of water through the alarm valve, and uses the sensor to sense the situation inside the water pipe, and then feeds back the abnormal situation to the alarm. The alarm notifies the management personnel that the system has failed so that the system can be repaired in time. When the valve fails, the existing single sprinkler pipe network is prone to cause the system to fail to operate normally due to a single failure, which may affect the normal operation of fire fighting.

[0003] In view of the above problems, a fault diagnosis device for a building automatic sprinkler fire extinguishing system is developed. Utility Model Content

[0004] In order to overcome the disadvantage that when a valve fails, the existing single sprinkler pipe network may easily cause the system to fail to operate normally due to a single failure, which may affect the normal operation of fire fighting, the utility model provides a fault diagnosis device for a building automatic sprinkler fire extinguishing system.

[0005] The technical solution of the present utility model is: a fault diagnosis device for an automatic sprinkler fire extinguishing system of a building, comprising an alarm valve, a first water pipe being threadedly connected to the lower portion of the alarm valve, a second water pipe being threadedly connected to the right side of the first water pipe, a third water pipe being threadedly connected to the upper side of the alarm valve, a screen being installed on the front side of the alarm valve, sensors being provided inside the first water pipe, the second water pipe and the third water pipe, a solenoid valve being provided on the upper right side of the second water pipe, a pressure gauge being provided on the upper right side of the third water pipe, an alarm being installed on the upper left side of the third water pipe, and a vibration detection mechanism being provided on the left side of the alarm valve.

[0006] As an optimal technical solution of the present invention, the vibration detection mechanism includes a first mounting part, the first mounting part is installed on the left side of the alarm valve, and a second mounting part symmetrical in upper and lower directions is installed on the right side of the alarm valve. The second mounting part and the first mounting part are fixed with screws, and a detector is installed on the left side of the first mounting part.

[0007] As an optimal technical solution of the present invention, a protective mechanism is also included, which includes a third mounting member. The third mounting member is installed on the upper side of the screen, a protective plate is rotatably connected to the third mounting member, and a clamping plate is connected to the rear of the protective plate.

[0008] As a preferred technical solution of the present invention, the second water pipe is a detachable connection structure.

[0009] As a preferred technical solution of the present invention, the third water pipe is a T-shaped structure.

[0010] As a preferred technical solution of the present invention, the clamping plate is clamped to the front side of the alarm valve.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model uses a sensor to sense the internal conditions of the water pipe. When the sensor senses an abnormal condition inside the water pipe, it transmits an alarm message to the alarm, indicating that the system has failed or is damaged, thereby notifying the management personnel to promptly repair the building's automatic sprinkler fire extinguishing system, and setting the second water pipe as a bypass valve. When there is a problem with the main valve or the sprinkler network, the second water pipe can be used as a backup path to ensure that the water flow can continue to reach the sprinkler head, thereby reducing the impact of failures in the first and third water pipes on the normal operation of the system. In the non-working state, the second water pipe can automatically drain the accumulated water in the pipe to prevent corrosion caused by accumulated water when not in use for a long time. When the system pressure is too high, the solenoid valve automatically opens to release excess pressure in the water pipe, protecting the system from damage and preventing pipe rupture or equipment damage caused by system overpressure.

[0013] 2. The utility model is provided with a vibration detection mechanism, which can detect the vibration degree of the alarm valve through the detector, so as to prevent the strong water flow from impacting the water pipe, causing the water pipe connection to loosen and the water pipe to rupture. At the same time, the protective mechanism protects the screen. When the management personnel views the system data, the protective plate can be flipped upwards until the card plate is connected to the front side of the alarm valve, thereby preventing the protective plate from falling off, so that the management personnel can view the system data intuitively.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] A fault diagnosis device for a building automatic sprinkler fire extinguishing system, such as Figure 1 and Figure 2 As shown, it includes an alarm valve 1, the lower part of the alarm valve 1 is threadedly connected to the first water pipe 11, the right side of the first water pipe 11 is threadedly connected to the second water pipe 12, the second water pipe 12 is a detachable connection structure, the upper side of the alarm valve 1 is threadedly connected to the third water pipe 13, the third water pipe 13 is a T-shaped structure, a screen 2 is installed on the front side of the alarm valve 1, the first water pipe 11, the second water pipe 12 and the third water pipe 13 are all equipped with sensors 3, the upper right side of the second water pipe 12 is provided with a solenoid valve 4, the upper right side of the third water pipe 13 is provided with a pressure gauge 5, the upper left side of the third water pipe 13 is installed with an alarm 6, and the left side of the alarm valve 1 is provided with a vibration detection mechanism 7.

[0022] It should be noted that the building automatic sprinkler fire extinguishing system is a highly efficient automatic fire extinguishing system, which is widely used in various types of buildings for preventing and controlling fires. The system can automatically start at the early stage of a fire, quickly spray water to extinguish the fire, effectively reduce fire losses, and ensure the safety of personnel. In order to ensure that the system can be detected by management personnel in a timely manner when a fault occurs, the system fault diagnosis device can be used to alarm, and the sensor 3 is installed inside the first water pipe 11, the second water pipe 12 and the third water pipe 13 to timely sense the internal conditions of the water pipes. Data such as the internal conditions of the water pipes will be displayed on the screen 2. Then the first water pipe 11, the second water pipe 12 and the third water pipe 13 are connected to the drain pipe. Among them, the first water pipe 11 and the third water pipe 13 are main valves, which are used for the main water spraying fire extinguishing work, and the second water pipe 12 is a bypass valve, which plays an auxiliary drainage role for the main valve. When the system is working, water flowing through the alarm valve 1 will activate the alarm device to notify the management personnel that the system has been activated. When the sensor 3 senses When an abnormal situation is detected inside the water pipe, an alarm message will be transmitted to the alarm 6, and then the alarm 6 will sound an alarm, indicating that the system has failed or been damaged. The alarm 6 reminds the management personnel to repair the building's automatic sprinkler fire extinguishing system in time. At the same time, the pressure gauge 5 can display the water pressure inside the water pipe so that the maintenance personnel can observe the water pressure inside the water pipe in real time. When there is a problem with the main valves or the sprinkler network such as the first water pipe 11 and the third water pipe 13, the second water pipe 12 can be used as a bypass valve as a backup path to ensure that the water flow can continue to reach the sprinkler head so as to continue to spray water outward to extinguish the fire, thereby reducing the impact of a single failure of the main valves such as the first water pipe 11 and the third water pipe 13 on the normal operation of the system. In the non-working state, the accumulated water in the pipe can be automatically discharged through the second water pipe 12 to prevent corrosion caused by accumulated water when not in use for a long time. When the system pressure is too high, the solenoid valve 4 automatically opens to release excess pressure in the water pipe to protect the system from damage and prevent pipe rupture or equipment damage caused by system overpressure.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1 and Figure 3 As shown, the vibration detection mechanism 7 includes a first mounting member 71. The first mounting member 71 is installed on the left side of the alarm valve 1, and a second mounting member 72 symmetrically installed on the right side of the alarm valve 1. The second mounting member 72 and the first mounting member 71 are fixed with screws, and a detector 73 is installed on the left side of the first mounting member 71.

[0025] like Figure 1 and Figure 4 As shown, it also includes a protective mechanism 8, which includes a third mounting member 81. The third mounting member 81 is installed on the upper side of the screen 2. A protective plate 82 is rotatably connected to the third mounting member 81. The rear of the protective plate 82 is connected to a clamping plate 83, and the clamping plate 83 is clamped to the front side of the alarm valve 1.

[0026] It should be noted that when the automatic sprinkler fire extinguishing system is working, the water fills the water pipes, and the strong water flow may cause an impact on the water pipes. Excessive water flow impact will cause the water pipe connections to loosen, and the water pipes may rupture, which will affect the system. The detector 73 can detect the degree of vibration of the alarm valve 1 so that the water pipes can be inspected and repaired in time to avoid safety hazards. In order to prevent the screen 2 from being damaged by external factors, the protective plate 82 can protect the screen 2. When the management personnel views the system data, the protective plate 82 can be flipped upwards until the snap-on plate 83 is aligned with the front side of the alarm valve 1, thereby preventing the protective plate 82 from falling off, so that the management personnel can view the system data intuitively.
