Description

Technical Field

[0001] This invention relates to the field of emergency lighting controller technology, and more specifically to a power failure self-test device for a fire emergency lighting system. Background Technology

[0002] The emergency lighting controller is the core of a fire emergency lighting system, possessing functions such as self-testing, power failure triggering, fault alarm, and linkage control. Its hardware architecture includes a main control unit, power module, communication interface, and display panel. In settings such as schools and pharmaceutical companies, emergency lighting controllers effectively improve fire safety levels and protect the lives and property of personnel.

[0003] Technical Problem: A search revealed Chinese Patent Publication No. CN116944144A, which discloses an easy-to-maintain emergency lighting controller, relating to the field of emergency lighting dust removal and cooling. The controller includes a base plate, with a controller housing fixedly connected to the top surface of the base plate. A rotating bolt is fixedly connected to the outer surface of the controller housing, and a control door is fixedly connected to the rotating shaft of the rotating bolt. A battery plate is fixedly connected to the inner surface of the controller housing, and a CPU processor is fixedly connected to the upper surface of the battery plate. A button panel is fixedly connected to the left side of the CPU processor. A ball screw mechanism is fixedly connected to the side of the battery plate away from the controller housing. A rotary dust collection mechanism is rotatably connected to the end of the ball screw mechanism away from the battery plate, and a brush plate mechanism is fixedly connected to the end of the ball screw mechanism away from the rotary dust collection mechanism. A pressing mechanism is fixedly connected to the side of the water collection mechanism away from the button panel. This invention utilizes the gravity of water to drive the blade shaft, generating wind to cool the device.

[0004] In practical use, the following problems still exist: First, the emergency lighting controller, with its internal circuit connections and multiple components, uses a water spray method for heat dissipation, which poses a significant safety hazard and fails to address the high temperatures and burns caused by fire. Furthermore, while the device includes a dust extraction mechanism to handle internal dust, the lack of any treatment on the heat dissipation vents on the controller's casing means that the device not only absorbs gases from inside the controller but also from the external environment. If used in dusty and humid environments, the dust extraction mechanism will draw in large amounts of moist dust from the external environment, clogging the heat dissipation vents and affecting the device's cooling performance. This moisture will also adhere to the electronic components, creating a significant safety hazard. Therefore, this application proposes a power-off self-test device for a fire emergency lighting system to solve the above problems. Summary of the Invention

The top spray head and the side spray heads are all connected to the cavity of the outer shell through an outlet pipe.

[0010] A further improvement of the technical solution of the present invention is that: a piston plate is movably connected to the top of the inner cavity of the outer shell, the piston plate can slide up and down along the inner cavity of the outer shell, the opening position of the water outlet pipe inside the outer shell is located at the bottom of the piston plate, the opening position of the outlet pipe inside the outer shell is located at the top of the piston plate, and there is a height difference between the water outlet pipe, the outlet pipe and the piston plate.

[0011] A further improvement of the technical solution of the present invention is that valves are movably connected to both the water outlet pipe and the outlet pipe.

[0012] A further improvement of the technical solution of the present invention is that: a plurality of telescopic rods are fixedly connected to the upper surface of the piston plate, and springs are sleeved on the outer surface of the telescopic rods.

[0013] A further improvement of the technical solution of the present invention is that: a trigger block is fixedly connected to the top of the inner cavity of the outer shell. When the piston plate moves up and abuts against the trigger block, the opening position of the outlet pipe inside the outer shell is at the bottom of the piston plate. At this time, the valve on the water outlet pipe is closed and the valve on the outlet pipe is opened. The cooling water in the outer shell is sprayed out through the outlet pipe, the top spray head and the side spray head to cool the outer surface of the outer shell and play a role in preventing scorching.

[0014] A further improvement of the technical solution of the present invention is that: a sealing plate is fixedly connected to one side of the door panel; when the door panel is closed, the sealing plate is movably connected to the inner wall of the outer shell; a slot is provided in the middle of the sealing plate; and a sealing ring is movably connected to the inner wall of the slot.

[0015] A further improvement of the technical solution of the present invention is that: a connecting air pipe is fixedly connected to the bottom of the outer shell, one end of the connecting air pipe is in through communication with the cavity inside the outer shell located between the top of the piston plate, and the other end of the connecting air pipe extends through the rotating shaft to the cavity of the door panel and the slot, and is in through communication with the inside of the sealing ring.

[0016] A further improvement of the technical solution of the present invention is that the sealing ring is made of a soft, elastic material.

[0017] A further improvement to the technical solution of the present invention is that: a water pump is fixedly connected to one end of the water inlet pipe, the input end of the water pump is connected to a water storage mechanism through a pipe, and the output end of the water outlet pipe is fixedly connected to the top of the water storage mechanism.

[0018] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0019] 1. This invention provides a power failure self-test device for a fire emergency lighting system. During normal use, cooling water is injected into the cavity of the outer casing through the water inlet pipe. As the water in the cavity gradually increases, it is discharged to the outside of the outer casing when it reaches the opening of the water outlet pipe. At this time, the water in the cavity of the outer casing can be used to cool the heat generated by the controller body during normal use. This avoids the problem of opening heat dissipation holes on the device casing, which would cause a large amount of damp dust to be sucked into the device in a relatively hot environment and adhere to the surface of electronic components, creating a significant safety hazard. When water is injected into the outer casing through the water inlet pipe, some of the cooling water will enter the door panel through the connecting water pipe, and simultaneously dissipate heat at the door panel. Combined with the action of the spray mechanism, it can effectively reduce the high temperature and scorching problems generated on the equipment in the event of a fire.

[0020] 2. This invention provides a power failure self-test device for a fire emergency lighting system. Cooling water inside the housing cavity is discharged through an outlet pipe to the top spray head and side spray heads, and then sprayed out. The water sprayed from the top spray head can form an annular water curtain that covers the housing. At the same time, multiple side spray heads located at the top of the housing are tilted inward, so that the cooling water sprayed from the side spray heads can flow along the outer surface of the housing. The top spray head and side spray heads work together to effectively reduce the high temperature and burning effects on the housing and controller body during a fire.

[0021] 3. This invention provides a power failure self-test device for a fire emergency lighting system. When a fire generates high temperatures, the water in the cavity of the outer shell will evaporate due to the heat, causing the air pressure in the cavity between the cooling water surface inside the outer shell and the piston plate to increase. This pushes the piston plate to gradually move upward, increasing the amount of cooling water evaporation. The piston plate continues to move upward to the top of the outlet pipe, at which point the cooling water can flow out from the outlet pipe to the top spray head and the side spray head, producing a spray cooling effect.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example:

[0026] like Figure 1-7 As shown, the present invention provides a power failure self-test device for a fire emergency lighting system, including a controller body 1. The controller body 1 is the prior art and includes a main control unit, a power module, a communication interface and a display panel, etc. It can realize functions such as self-testing, power failure triggering, fault alarm and linkage control of the fire lighting system. The controller body 1 is covered by a shell 2, which is hollow inside. The outer surface of the shell 2 is movably connected to a door panel 3 through a pivot, which is also hollow inside.

[0027] A water inlet pipe 4 is fixedly connected to the bottom of the outer shell 2. One end of the water inlet pipe 4 is connected to a water injection structure to inject cooling water into the cavity of the outer shell 2. A water outlet pipe 7 is fixedly connected to the upper side of the outer shell 2 to drain the water in the outer shell 2. A drain hole is also provided at the bottom of the outer shell 2. It is closed during normal use. When it is necessary to completely drain the cooling water in the cavity of the outer shell 2, the cooling water can be drained through the drain hole.

[0028] A water pipe 14 is fixedly connected to the bottom of the outer shell 2, and one end of the water pipe 14 is connected to the inside of the door panel 3 through a pivot.

[0029] A spraying mechanism is provided at the top of the outer casing 2.

[0030] During normal use, cooling water is injected into the cavity of the outer casing 2 through the water inlet pipe 4. The water in the cavity gradually increases and is discharged to the outside of the outer casing 2 when it reaches the opening of the water outlet pipe 7. At this time, the water in the cavity of the outer casing 2 is in a flowing state, which can be used to cool the heat generated by the controller body 1 during normal use. This avoids the problem of opening heat dissipation holes on the equipment casing, which would cause a large amount of damp dust to be sucked into the equipment in a relatively hot environment and adhere to the surface of electronic components, creating a significant safety hazard. When the water inlet pipe 4 injects water into the outer casing 2, some of the cooling water will enter the door panel 3 through the connecting water pipe 14, and simultaneously dissipate heat at the door panel 3. With the help of the spray mechanism, it can effectively reduce the high temperature and burning problems of the equipment in the event of a fire.

[0031] Furthermore, the spraying mechanism includes a top spray head 12 fixedly connected to the upper surface of the outer shell 2 and multiple side spray heads 13 fixedly connected to the top perimeter of the outer shell 2. The top spray head 12 and the side spray heads 13 are all connected to the cavity of the outer shell 2 through the outlet pipe 11. The cooling water in the cavity of the outer shell 2 is led out through the outlet pipe 11 to the top spray head 12 and the side spray heads 13 and sprayed out. The water sprayed out by the top spray head 12 can form an annular water curtain that covers the outer shell 2. At the same time, the multiple side spray heads 13 located at the top of the outer shell 2 are all tilted inward, so that the cooling water sprayed out by the side spray heads 13 can flow along the outer surface of the outer shell 2. The top spray head 12 and the side spray heads 13 cooperate with each other to effectively reduce the high temperature and burning effect on the outer shell 2 and the controller body 1 when a fire occurs.

[0032] Furthermore, a piston plate 8 is movably connected to the top of the inner cavity of the outer shell 2. The piston plate 8 can slide up and down along the inner cavity of the outer shell 2. The opening of the water outlet pipe 7 inside the outer shell 2 is located at the bottom of the piston plate 8, and the opening of the outlet pipe 11 inside the outer shell 2 is located at the top of the piston plate 8. There is a height difference between the water outlet pipe 7, the outlet pipe 11 and the piston plate 8. When the fire generates high temperature, the water in the cavity of the outer shell 2 will be heated and evaporated, which will increase the air pressure in the cavity between the cooling water surface inside the outer shell 2 and the piston plate 8, pushing the piston plate 8 to gradually move upward. The amount of cooling water evaporation increases, and the piston plate 8 continues to move upward to the top of the outlet pipe 11. At this time, the cooling water can flow out from the outlet pipe 11 to the top spray head 12 and the side spray head 13 to produce a spray cooling effect.

[0033] Furthermore, valves are movably connected to both the water outlet pipe 7 and the outlet pipe 11. When the piston plate 8 gradually rises to the top of the outlet pipe 11 under the action of increased air pressure, the valve on the water outlet pipe 7 closes and the valve on the outlet pipe 11 opens, so that the cooling water in the cavity of the outer shell 2 can be sprayed out through the outlet pipe 11. The valve is existing technology and can be an electrically controlled valve, etc.

[0034] Furthermore, multiple telescopic rods 9 are fixedly connected to the upper surface of the piston plate 8, and springs 10 are sleeved on the outer surface of the telescopic rods 9. When the piston plate 8 moves upward, the telescopic rods 9 and springs 10 are compressed. When the high temperature generated by the fire gradually disappears, the piston plate 8 will gradually return to its original position to ensure that subsequent use is not affected.

[0035] Furthermore, a trigger block 19 is fixedly connected to the top of the inner cavity of the outer shell 2. When the piston plate 8 moves upward and abuts against the trigger block 19, the opening position of the outlet pipe 11 inside the outer shell 2 is at the bottom of the piston plate 8. At this time, the valve on the water outlet pipe 7 is closed, and the valve on the outlet pipe 11 is open. The cooling water in the outer shell 2 is sprayed out through the outlet pipe 11, the top spray head 12, and the side spray head 13 to cool the outer surface of the outer shell 2 and prevent burning. When the piston plate 8 is not abutting against the trigger block 19, the high temperature generated by the external environment can be cooled by the cooling water flowing inside the outer shell 2, which can ensure that the use of the controller body 1 is not affected by the high temperature. As the temperature rises, the air pressure inside the outer shell 2 increases. When the piston plate 8 gradually moves upward and abuts against the trigger block 19, it indicates that the high temperature generated by the fire in the external environment is high, and protection and cooling are required by the spraying action of the top spray head 12 and the side spray head 13.

[0036] Furthermore, a sealing plate 16 is fixedly connected to one side of the door panel 3. When the door panel 3 is closed, the sealing plate 16 is movably connected to the inner wall of the outer casing 2. A slot 17 is provided in the middle of the sealing plate 16, and a sealing ring 18 is movably connected to the inner wall of the slot 17. When the top spray head 12 and the side spray head 13 spray water, by inflating the sealing ring 18, the sealing performance at the connection between the sealing plate 16 and the inner wall of the outer casing 2 can be enhanced, preventing the sprayed cooling water from entering the interior of the outer casing 2, which could cause the controller body 1 to short-circuit when exposed to water.

[0037] Furthermore, a connecting vent pipe 15 is fixedly connected to the bottom of the outer casing 2. One end of the connecting vent pipe 15 is connected to the cavity inside the outer casing 2 between the top of the piston plate 8 and the cavity inside the door panel 3 and the slot 17 via a rotating shaft, and is connected to the inside of the sealing ring 18. The connecting vent pipe 15 connects the sealing ring 18 with the cavity between the top of the outer casing 2 and the upper surface of the piston plate 8. Under high temperature, the piston plate 8 gradually moves upward, and the gas in the cavity between the upper surface of the piston plate 8 and the outer casing 2 is forced into the sealing ring 18 through the connecting vent pipe 15, causing the sealing ring 18 to be inflated and collide, thereby enhancing the sealing performance at the connection between the sealing plate 16 and the outer casing 2.

[0038] Furthermore, the sealing ring 18 is made of a soft, elastic material, which facilitates the inflation and deflation of the sealing ring 18.

[0039] Furthermore, a water pump 5 is fixedly connected to one end of the water inlet pipe 4. The input end of the water pump 5 is connected to a water storage mechanism 6 through a pipe. The output end of the water outlet pipe 7 is fixedly connected to the top of the water storage mechanism 6. The water storage mechanism 6 can store a certain amount of cooling water for regular heat dissipation or for cooling, protection, and prevention of burns when a fire occurs and high temperatures are reached.
