[0018] 1.

[0020] 3. A fire warning device based on multi-parameter fusion judgment. The drive motor and swing arm enable the fire extinguishing component to swing, expanding the fire extinguishing range. By adjusting the swing angle and speed of the swing arm, it can flexibly respond to fire sources of different sizes and locations, improving the flexibility and adaptability of fire extinguishing.

[0021] 4. A fire warning device with multi-parameter fusion judgment, in which the various components cooperate efficiently through a transmission mechanism and rationally distribute fire water, not only improves the stability and durability of the device, but also facilitates subsequent maintenance and upkeep. The modular design of the various components also makes replacement and repair more convenient.

DETAILED DESCRIPTION

[0033] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0034] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Example 1:

[0036] A fire warning device with multi-parameter fusion judgment, such as Figures 1 to 9 As shown, it includes a spray module, a temperature sensing module and a smoke warning module. The spray module includes a support and a fire extinguishing assembly fixed on the support. The fire extinguishing assembly includes a top seat 23 and a bottom cover 18. A sliding sleeve 27 is welded to the bottom of the top seat 23, and a sliding frame 28 is welded to the top of the bottom cover 18. A leakage hole 35 is opened on the circumferential outer wall of the sliding frame 28, and the sliding frame 28 and the top seat 23 are slidably connected. A spring 21 is clamped between the bottom outer wall of the top seat 23 and the top outer wall of the bottom cover 18. A nozzle 19 is fixed to the bottom of the bottom cover 18. The side wall of the top seat 23 A connecting plate 1 36 is welded to the bottom cover 18, and a connecting plate 2 37 is welded to the side wall of the bottom cover 18. A sliding sleeve 16 is welded to the bottom outer wall of the connecting plate 1 36, and a sliding frame 17 is welded to the top outer wall of the connecting plate 2 37. The sliding frame 17 and the sliding sleeve 16 are slidably connected. A permanent magnet 24 is fixed to the top outer wall of the sliding frame 17 by screws, and an electromagnet 22 used in conjunction with the permanent magnet 24 is fixed to the top inner wall of the sliding sleeve 16 by screws. The outer cover 2 10 is fixed to the bottom outer wall of the top seat 23, and the outer cover 15 slidably connected to the outer cover 2 10 is fixed to the top outer wall of the bottom cover 18.

[0037] When a fire occurs, a fire extinguishing assembly can be provided to spray toward the fire point to extinguish the fire. By providing multiple groups of fire extinguishing assemblies and arranging the multiple groups of fire extinguishing assemblies in a straight line, the range of the spray fire extinguishing can be increased.

[0038] By setting a sliding connection between the sliding frame 28 and the sliding sleeve 27 and opening a leakage hole 35 on the sliding frame 28, when the flow rate during the spraying needs to be adjusted, the distance that the sliding frame 28 slides along the sliding sleeve 27 is set, thereby adjusting the opening size of the leakage hole 35, and thus achieving the adjustment of the spraying flow rate. During the adjustment, the electromagnet 22 is provided to generate an attraction to the permanent magnet 24 after being energized. During the process of the permanent magnet 24 being attracted, the sliding frame 17 moves upward along the sliding sleeve 16. This ensures that the leak hole 35 is completely covered by the second sliding sleeve 27 in the initial stage. When spraying fire extinguishing is required, after the attraction of the permanent magnet 24 weakens, the first sliding frame 17 moves downward along the first sliding sleeve 16 under the action of the rebound force of the spring 21. During this process, the second sliding frame 28 also moves downward relative to the second sliding sleeve 27, causing the leak hole 35 to gradually extend from the bottom of the second sliding sleeve 27. The fire-fighting water enters the second outer cover 10 and the first outer cover 5 through the second sliding sleeve 27 and the leak hole 35, and is finally sprayed out through the sprinkler 19 to extinguish the fire.

[0039] The temperature sensing module and smoke warning module are used to sense the temperature and smoke concentration data at the fire scene respectively. By inputting the data into the processing terminal, the processing terminal comprehensively analyzes the parameters to make more accurate fire warning decisions. When the temperature rises sharply and the smoke concentration reaches or exceeds the preset threshold at the same time, the processing terminal outputs a higher fire probability or a more urgent warning signal. When the sprinkler module is started, its usage process is combined with the smoke concentration data. When the control terminal determines that a fire is about to occur or has occurred through the smoke warning module, it controls the sprinkler module to spray and extinguish the fire.

[0040] The temperature sensing module includes a shielding plate 26 and a circular hole 25. The shielding plate 26 is slidably connected to the side wall of the sliding sleeve 16, and the circular hole 25 is opened on the surface of the shielding plate 26. The top outer wall of the connecting plate 36 is welded with a receiving tube 30, and the inner wall of the receiving tube 30 is slidably connected to a push plate 32. The outer wall of one side of the push plate 32 is fixed with a connecting plate 13, and the end of the connecting plate 13 away from the push plate 32 is fixed to the top outer wall of the shielding plate 26. An airbag 29 is installed between the outer wall of one side of the push plate 32 and the inner wall of one side of the receiving tube 30.

[0041] In the initial stage when there is no fire, the circular hole 25 and the electromagnet 22 are in a facing position with the permanent magnet 24. At this time, the magnetic force generated by the electromagnet 22 acts on the surface of the permanent magnet 24 through the circular hole 25, so that the electromagnet 22 attracts the permanent magnet 24. When a fire occurs, the temperature around the fire point will rise sharply. When the airbag 29 is heated, the gas stored inside it will expand after being heated. In this embodiment, the gas stored in the airbag 29 is preferably one of hydrogen, oxygen or nitrogen. After the gas is heated and expanded, the airbag 29 gradually deforms. After the deformation of the airbag 29, it drives the push plate 32 and the connecting plate 13 to move laterally along the accommodating tube 30. During the movement, the connecting plate 13 drives the shielding plate 26 to slide along the sliding sleeve 16. During the sliding process, the position of the circular hole 25 relative to the electromagnet 22 will also change. When the circular hole 25 gradually moves away from the sliding sleeve 16, due to the shielding effect of the shielding plate 26, the attraction of the electromagnet 22 to the permanent magnet 24 will gradually decrease under the shielding of the shielding plate 26. The sliding frame 28 gradually moves away from the sliding sleeve 27 under the rebound force of the spring 21, so that the fire water eventually enters the outer cover 2 10 and the outer cover 1 5 through the sliding sleeve 27 and the leakage hole 35, and is finally sprayed out through the nozzle 19 to extinguish the fire.

[0042] By using the airbag 29 as a temperature-sensing trigger, the sliding frame 28 can move downward relative to the sliding sleeve 27 in the area where the fire occurs, thereby ensuring that the fire-fighting water is sprayed out through the nozzle 19 to extinguish the fire. The temperature in the area where no fire occurs will not rise, and the airbag 29 will not be deformed. The sliding sleeve 27 will cover the leakage hole 35 so that the fire-fighting water will not enter the outer cover 2 10 and the outer cover 1 5 and be sprayed out through the nozzle 19. This structural design ensures that when a fire occurs, the fire-fighting water is concentrated on the area near the fire point to extinguish the fire, avoiding the waste of fire-fighting water while preventing the fire-fighting components where there is no fire from diverting the fire-fighting water, thereby improving the fire-fighting efficiency.

[0043] The support member includes a suspension frame 1 and a connecting rod 2, the connecting rod 2 is welded between the two suspension frames 1, and a support plate 4 is welded to the outer wall of one side of the suspension frame 1 through a fixing plate 38, a through hole opened in the side wall of the support plate 4 is rotatably connected to the rotating shaft 1, and a swing arm 7 is fixed to the outer wall of the circumference of the rotating shaft 1, and the surface of the swing arm 7 is rotatably connected to the moving arm 31 through the rotating shaft 2, a mounting seat 6 is welded to the side wall of the swing arm 7, and a pipe 20 is welded between the mounting seat 6 and the top outer wall of the top seat 23, a drive motor 8 is fixed to the outer wall of one side of the support plate 4 by bolts, and the output end of the drive motor 8 is connected to one end of one of the rotating shafts through a coupling;

[0044] When the fire extinguishing assembly sprays to extinguish a fire, in order to increase the spraying range, a drive motor 8 is provided to synchronously drive the swing arm 7 to rotate during the rotation of the drive shaft. During the rotation, the swing arm 7 drives the fire extinguishing assembly fixed thereon to swing, thereby adjusting the spraying angle and spraying range of the nozzle 19 and expanding the fire extinguishing range. By providing a movable arm 31, the drive motor 8 indirectly drives multiple groups of fire extinguishing assemblies to swing synchronously.

[0045] The top of the pipe 20 is connected to a multi-way pipe 9 through a joint, and a solenoid valve 3 is fixed to the end of the multi-way pipe 9 away from the pipe 20;

[0046] By providing a multi-way pipe 9, fire-fighting water can be introduced into the fire-fighting assembly, and by providing a solenoid valve 3, the use of fire-fighting water can be controlled.

[0047] The smoke warning module includes a connecting plate 13 and a top cover 14. The connecting plate 13 is welded to the outer wall of one side of the connecting rod 2, and the top cover 14 is welded to the bottom of the connecting plate 13. A smoke alarm 33 is fixed to the bottom of the top cover 14.

[0048] When a fire occurs, the smoke alarm 33 will sound an alarm after sensing that the smoke concentration has reached a certain value. In this embodiment, the solenoid valve 3, the smoke alarm 33 and the control terminal are electrically connected. When the smoke alarm 33 senses that the smoke concentration has reached a certain value, the signal is fed back to the control terminal. After receiving the signal, the control terminal controls the solenoid valve 3 to open. With this operation method, the opening of the solenoid valve 3 needs to be judged in combination with the smoke concentration monitored by the smoke alarm 33, thereby avoiding the situation where there is no fire but the airbag 29 is deformed due to the high ambient temperature, resulting in the fire extinguishing component spraying by mistake, thereby ensuring the accuracy of the fire warning and the safety of use.

[0049] The bottom of the top cover 14 is fixed with a mounting box 11 by screws, and the side wall of the mounting box 11 is provided with a filter screen 34, and the side wall of the movable arm 31 is fixed with a brush plate 15 used in conjunction with the filter screen 34;

[0050] In order to avoid false alarms caused by excessive dust accumulation on the surface of the smoke alarm 33, the smoke alarm 33 can be covered by providing an installation box 11, and the dust and other particulate matter in the environment can be filtered and intercepted by the filter 34. At the same time, the smoke alarm 33 can be protected to prevent the smoke alarm 33 from being damaged by external impact or collision. When the surface of the filter 34 needs to be cleaned, the driving motor 8 is used to indirectly drive the moving arm 31 to swing, so that the brush plate 15 cleans the dust attached to the surface of the filter 34, thereby preventing the dust from clogging the mesh of the filter 34.

[0051] The same multi-way pipe 12 is fixed on the top of the two installation boxes 11, and the end of the multi-way pipe 12 away from the installation box 11 is connected to the negative pressure fan;

[0052] By connecting the multi-way pipe 2 12 and the negative pressure fan, the air flow rate is accelerated when the negative pressure fan is started, thereby accelerating the absorption rate of smoke when a fire occurs, so that the smoke alarm 33 can sense the smoke more quickly.

[0053] When in use, the temperature-sensing airbag 29, as a temperature-sensing trigger, maintains its original shape under normal conditions and does not interfere with the attraction of the electromagnet 22 to the permanent magnet 24. It maintains the relative position of the sliding frame 28 and the sliding sleeve 27, ensuring that the leakage hole 35 is completely covered to prevent the leakage of fire water. When a fire occurs, the temperature around the fire point rises sharply, and the airbag 29 expands due to the heat, pushing the push plate 32 and the connecting plate 13 to move, thereby driving the shielding plate 26 to slide. The circular hole 25 on the shielding plate 26 gradually moves away from the electromagnet 22, weakening the attraction of the electromagnet to the permanent magnet 24. As the electromagnetic attraction weakens, the rebound force of the spring 21 drives the sliding frame 28 downward relative to the sliding sleeve 27, and the leakage hole 35 is gradually exposed, allowing the fire water to pass through. The fire water is introduced from the pipeline 20 through the multi-way pipe 1 9. After receiving the fire signal, the solenoid valve 3 opens to allow water to flow through. The fire water enters the outer cover 2 10 and the inner part of the outer cover 1 5 through the sliding sleeve 27 and the leakage hole 35. The smoke is sprayed out by the nozzle 19 to extinguish the fire point. In order to improve the fire extinguishing efficiency, the device uses a driving motor 8 to drive the swing arm 7 to rotate. The swing arm 7 drives multiple groups of fire extinguishing components to swing synchronously through the movable arm 31 connected to the second rotating shaft, thereby adjusting the spraying angle and range of the nozzle 19. When a fire occurs, the smoke concentration in the air gradually increases. Once the smoke concentration reaches the preset alarm threshold, the smoke alarm 33 will send an alarm signal, which is then transmitted to the control terminal. After receiving the signal, the control terminal starts the solenoid valve 3 to control the fire extinguishing component to spray. By combining the opening of the solenoid valve 3 with the monitoring results of the smoke alarm 33, the accidental spraying caused by the deformation of the airbag 29 due to the high ambient temperature is effectively avoided, thereby ensuring the accuracy and safety of the fire warning. When the negative pressure fan is started, the suction force generated accelerates the flow rate of the surrounding air, quickly absorbs the smoke when a fire occurs, and enables the smoke alarm 33 to sense the smoke faster, thereby shortening the alarm response time.

[0054] The above is a preferred specific embodiment of the present invention, and the scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions and improvements made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with existing technologies or public common sense, within the spirit and principles of the present invention, should be covered by the scope of protection of the present invention.
