Description

Technical Field

[0001] The invention belongs to the technical field of fire protection, and in particular relates to a three-in-one fire protection system. Background Art

[0002] Mercury sprinkler heads are often used in fire sprinkler systems. The operating temperature of mercury sprinkler heads is 68°C. When the fire environment reaches 68°C, the high temperature causes the mercury inside the glass container to expand and burst the glass container, causing the water outlet at the end of the mercury sprinkler head to lose its seal, allowing the water flow inside the fire pipe to spray out from the mercury sprinkler head outlet to extinguish the fire.

[0003] Although mercury sprinkler heads can play a certain role in firefighting, they have some defects in use. For example, the starting temperature is high. When the sensing temperature of the mercury sprinkler heads installed at a high place on the scene reaches 68°C, the ground at the scene is already raging with fire, and the ambient temperature of 68°C has already exceeded the tolerance limit of the trapped people at the fire scene. It cannot be started in time before the ambient temperature reaches the tolerance limit of the trapped people. Moreover, after the temperature reaches 68°C, the temperature of the fire water sprayed by the mercury sprinkler heads will be higher than 68°C. The high-temperature water will scald the fire rescue personnel entering the fire scene for rescue. It can be seen that mercury sprinkler heads violate the firefighting work principles of both fast and accurate in some firefighting places, and cannot effectively protect the personal safety and property safety of on-site personnel. Summary of the invention

[0004] The object of the present invention is to provide a three-in-one fire fighting system to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] Trinity fire protection system, including:

[0007] An emergency light, wherein the emergency light is connected to a backup power supply, the backup power supply is connected to the mains, and the backup power supply is electrically connected to a power supply port;

[0008] A smoke alarm, the smoke alarm being electrically connected to the power supply port;

[0009] A water pipe, the water pipe being connected to a mercury-type sprinkler head and an open sprinkler head arranged in parallel, the open sprinkler head being connected to a normally closed electric valve, and the electric valve being electrically connected to the power supply port;

[0010] A controller is electrically connected to the power supply port, and the smoke alarm and the electric valve are both electrically connected to the controller.

[0011] Preferably, the three-in-one fire protection system further comprises a manual switch, the manual switch is electrically connected to the power supply port, and the manual switch and the smoke alarm are electrically connected to the controller in parallel, and the manual switch is used to simulate the activation of the smoke alarm.

[0012] Preferably, the manual switch is connected to the side wall of the emergency light.

[0013] Preferably, the backup power supply is fixedly mounted on the inner wall of the emergency light, and the power supply port is arranged on the side wall of the emergency light.

[0014] Preferably, the three-in-one fire protection system further includes a filter valve, and the filter valve and the electric valve are arranged in sequence along the water flow direction.

[0015] Preferably, the filter valve is a brass filter ball valve.

[0016] Preferably, the electric valve is electrically connected in parallel with a fire control room alarm.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention arranges a backup power supply inside the emergency light, and arranges an open type sprinkler head in parallel with the mercury sprinkler head, the opening and closing of the open type sprinkler head is controlled by an electric valve, the electric valve is connected in series with the smoke alarm, and the controller controls the opening of the electric valve according to the alarm signal feedback of the smoke alarm. When a fire occurs at the installation site, the smoke alarm senses the fire smoke and then gives an alarm, and transmits the signal to the controller, which controls the electric valve to open. At this time, the fire water inside the fire hose is directly sprayed from the open type sprinkler head to extinguish the fire, which can effectively avoid the spread of fire caused by the delayed opening of the mercury sprinkler head. The three fire fighting equipments of the emergency light, the smoke alarm and the sprinkler head are connected together to form an integrated fire fighting system, which can effectively deal with fire.

[0019] The backup power supply and the emergency light are connected to the mains power supply. The mains power supply charges the emergency light power supply and the backup power supply at the same time. The emergency light provides sufficient installation space for the backup power supply. The backup power supply can also be charged through the mains power connection of the emergency light, without the need for additional power supply. It is also convenient for operators to check the emergency light power supply and the backup power supply at the same time. The backup power supply supplies power to the smoke alarm and the electric valve. Even if the power is cut off at the fire scene, the smoke alarm and the electric valve can still work normally, helping the open sprinkler to open and spray water in time. When the temperature at the fire scene is high and the circuit of the electric valve is disconnected, the high temperature will also cause the mercury sprinkler head to work. The cooperation of the mercury sprinkler head and the open sprinkler head can effectively broaden the prevention scope of the fire protection system and start the fire sprinkler for protection before the fire spreads. In order to ensure that the electric valve can work normally, the maintenance personnel can manually close the manual switch to simulate the alarm signal of the smoke alarm. At this time, the controller will control the electric valve to open, and verify whether the electric valve is operating normally by observing whether the open sprinkler head sprays water.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1 - Figure 3 As shown, the three-in-one fire protection system includes:

[0027] An emergency light 1, wherein a backup power supply 2 is fixedly connected to the inner wall of the emergency light 1, and the emergency light 1 is a common model on the market. The emergency light 1 itself has a built-in backup energy storage power supply, and the backup power supply 2 is independent of the backup energy storage power supply of the emergency light 1. The emergency light 1 and the backup power supply 2 are electrically connected in parallel and are both electrically connected to the mains. A power supply port 3 is fixedly connected to the side wall of the emergency light 1, and a manual switch 4 is fixedly connected to the side wall of the emergency light 1;

[0028] Smoke alarm 5, the smoke alarm 5 can be selected from common models on the market, the manual switch 4 is electrically connected in parallel with the smoke alarm 5, and the manual switch 4 is used to simulate the start of the smoke alarm 5;

[0029] A water pipe 6, to which a mercury-type sprinkler head 7 and an electric valve 9 are fixedly connected, the electric valve 9 is in a normally closed state, an open sprinkler head 10 is fixedly connected at the end of the electric valve 9, the water flow inside the water pipe 6 passes through the electric valve 9 and the open sprinkler head 10 in sequence, the backup power supply 2 is connected to the power supply port 3 by wire, and is electrically connected to the smoke sensor 5 and the electric valve 9 through the power supply port 3, the mercury-type sprinkler head 7 and the open sprinkler head 10 are connected in parallel, and the open sprinkler head 10 is normally open;

[0030] A controller, the controller is electrically connected to the power supply port 3, and the smoke alarm 5 and the electric valve 9 are both electrically connected to the controller;

[0031] The power supply port 3 is electrically connected to the smoke alarm 5. When the smoke alarm 5 senses smoke, the circuit of the electric valve 9 is connected, and a feedback signal is transmitted to the controller, and the controller controls the electric valve 9 to open.

[0032] As can be seen from the above, when a fire occurs at the fire protection system site, the smoke generated by the fire is transmitted to the smoke alarm 5. After the smoke alarm 5 senses the smoke, it sends an alarm signal to the controller. The controller connects the circuit of the electric valve 9, so that the electric valve 9 is powered on and opened. Since the open nozzle 10 is normally open, the opened electric valve 9 connects the open nozzle 10 with the water pipe 6, and the open nozzle 10 sprays fire water outward to extinguish the fire. When the fire causes the mains power to be cut off, the backup power supply 2 continues to supply power to the smoke sensor 5 and the electric valve 9 to ensure that the smoke sensor 5 and the electric valve 9 can continue to function. As the fire spreads, the backup power supply 2 continues to supply power to the smoke sensor 5 and the electric valve 9 to ensure that the smoke sensor 5 and the electric valve 9 can continue to function. When the delay causes the smoke sensor 5 or the electric valve 9 to be powered off, even if the electric valve 9 is closed and the open sprinkler 10 is cut off from water, the high temperature will cause the mercury sprinkler head 7 to open at the same time. The opened mercury sprinkler head 7 will take over the work of the open sprinkler head 10 to spray fire water to the fire scene to extinguish the fire, thereby maintaining the continuous operation of the fire sprinkler. In daily maintenance work, in order to ensure that the electric valve 9 can operate normally, the user can turn on the manual switch 4, which will turn on the power supply of the electric valve 9, so that the maintenance personnel can check whether the electric valve 9 can operate normally and cause the open sprinkler 10 to spray fire water.

[0033] Embodiment 2:

[0034] See also Figure 1 - Figure 3 As shown, the three-in-one fire protection system includes:

[0035] An emergency light 1, wherein a backup power supply 2 is fixedly connected to the inner wall of the emergency light 1, and the emergency light 1 is a common model on the market. The emergency light 1 itself has a built-in backup energy storage power supply, and the backup power supply 2 is independent of the backup energy storage power supply of the emergency light 1. The emergency light 1 and the backup power supply 2 are electrically connected in parallel and are both electrically connected to the mains. A power supply port 3 is fixedly connected to the side wall of the emergency light 1, and a manual switch 4 is fixedly connected to the side wall of the emergency light 1;

[0036] Smoke alarm 5, the smoke alarm 5 can be selected from common models on the market, the manual switch 4 is electrically connected in parallel with the smoke alarm 5, and the manual switch 4 is used to simulate the start of the smoke alarm 5;

[0037] A water pipe 6, to which a mercury-type sprinkler head 7 and an electric valve 9 are fixedly connected, the electric valve 9 is in a normally closed state, an open sprinkler head 10 is fixedly connected at the end of the electric valve 9, the water flow inside the water pipe 6 passes through the electric valve 9 and the open sprinkler head 10 in sequence, the backup power supply 2 is connected to the power supply port 3 by wire, and is electrically connected to the smoke sensor 5 and the electric valve 9 through the power supply port 3, the mercury-type sprinkler head 7 and the open sprinkler head 10 are connected in parallel, and the open sprinkler head 10 is normally open;

[0038] A controller, the controller is electrically connected to the power supply port 3, and the smoke alarm 5 and the electric valve 9 are both electrically connected to the controller;

[0039] The power supply port 3 is electrically connected to the smoke alarm 5. When the smoke alarm 5 senses smoke, the circuit of the electric valve 9 is connected, and a feedback signal is transmitted to the controller, and the controller controls the electric valve 9 to open. The controller can be a single-chip microcomputer or other control elements. The function of the controller is to receive the alarm signal of the smoke alarm 5 and send an opening instruction to the electric valve 9.

[0040] As can be seen from the above, when a fire occurs at the fire protection system site, the smoke generated by the fire is transmitted to the smoke alarm 5. After the smoke alarm 5 senses the smoke, it sends an alarm signal to the controller. The controller connects the circuit of the electric valve 9 to control the electric valve 9 to open. Since the open nozzle 10 is normally open, the opened electric valve 9 connects the open nozzle 10 with the water pipe 6. The open nozzle 10 sprays fire water outward to extinguish the fire. When the fire causes the mains power to be cut off, the backup power supply 2 continues to supply power to the smoke sensor 5 and the electric valve 9 to ensure that the smoke sensor 5 and the electric valve 9 can continue to function. When the smoke sensor 5 or the electric valve 9 is powered off, even if the electric valve 9 is closed and the open sprinkler 10 is cut off from water, the high temperature will cause the mercury sprinkler head 7 to open. The opened mercury sprinkler head 7 will take over the work of the open sprinkler head 10 to spray fire water to the fire scene to extinguish the fire, thereby maintaining the continuous operation of the fire sprinkler. In daily maintenance work, in order to ensure that the electric valve 9 can operate normally, the user can turn on the manual switch 4, which will turn on the power supply of the electric valve 9, making it convenient for the maintenance personnel to check whether the electric valve 9 can operate normally and cause the open sprinkler 10 to spray fire water.

[0041] The electric valve 9 is electrically connected in parallel with the fire control room alarm 11. After the electric valve 9 is opened, the circuit of the fire control room alarm 11 is connected and an alarm is sounded, so that the personnel of the fire control room can understand the fire situation in time.

[0042] The filter valve 8 is a brass filter ball valve, which is installed between the water pipe 6 and the open nozzle 10. It can effectively filter out impurities in the fire water in the water pipe 6, prevent the impurities in the fire water from flowing into the electric valve 9 and affecting the operation of the electric valve 9, and ensure that the electric valve 9 can function stably for a long time.
