Description

Technical Field

[0001] This invention relates to the field of fire monitoring technology, and specifically discloses a fire alarm device with a fire extinguishing structure. Background Technology

[0002] Modern society places great emphasis on fire prevention and control. It is crucial to detect fires as early as possible through fire alarm devices, alerting personnel so they can quickly deploy firefighting resources to extinguish the blaze and prevent its spread and economic losses. In outdoor locations with flammable materials, such as substations, the impact of fires is extremely severe, yet the means of limiting and detecting them are limited. Typically, substations rely on flame detectors installed at multiple fixed locations. This method has limited coverage and fails to fully utilize the detectors' detection radius. Furthermore, when the ignition point is in the detector's blind spot, it cannot be detected promptly, delaying the discovery of the fire and its location, thus hindering alarm activation and allowing the fire to spread further, increasing the difficulty of subsequent firefighting. Summary of the Invention

[0003] To overcome the shortcomings of existing flame detectors in terms of insufficient monitoring range, a fire alarm device with a fire extinguishing structure is provided.

[0004] The technical solution is as follows: A fire alarm device with a fire extinguishing structure includes a housing, on which uniformly distributed filter screens are fixedly connected. A first filter screen is fixedly connected to the bottom side of the housing, and a rotating ring is rotatably connected to the first filter screen. A second filter screen is fixedly connected to the inner side of the housing via a support rod, and the second filter screen is rotatably connected to the rotating ring. A first electric shaft is rotatably connected to the side of the rotating ring away from the filter screen. A support rod is fixedly connected to the first electric shaft. A servo motor is fixedly connected to the support rod via a bracket. A transmission gear is fixedly connected to the output shaft of the servo motor. A gear ring that meshes with the transmission gear on the output shaft of the servo motor is fixedly connected to the second filter screen. A second electric shaft is rotatably connected to the side of the support rod away from the first electric shaft. A flame detector is fixedly connected to the second electric shaft. A smoke sensor is fixedly connected inside the housing. A buzzer is fixedly connected to the outer side of the housing. A climbing mechanism for climbing and falling is provided on the outer side of the housing. A cleaning mechanism for cleaning itself and the flame detector is provided on the housing.

[0005] Furthermore, the climbing mechanism includes symmetrically distributed support frames, all of which are fixed to the outer side of the outer shell. Symmetrically distributed electric friction wheels are mounted on the side of the outer shell near the support frames via brackets. A sliding block is slidably connected to the support frame, and a symmetrically distributed clamping block is hinged to the sliding block. A first electric push rod is hinged between the symmetrically distributed clamping blocks. A symmetrically distributed fixing plate is fixed to one of the sliding blocks, and a first elastic element is fixed between the symmetrically distributed fixing plate and the sliding block near the outer shell. One of the support frames is provided with a windproof assembly for shielding the filter screen.

[0006] Furthermore, the cleaning mechanism includes an L-shaped fixing frame, which is fixed to the side of the support rod away from the servo motor. A pneumatic telescopic rod is fixed to the side of the L-shaped fixing frame near the first filter screen. A second elastic element is fixed between the telescopic end of the pneumatic telescopic rod and the L-shaped fixing frame. A pneumatic piston rod communicating with the pneumatic telescopic rod is fixed to the side of the L-shaped fixing frame near the flame detector. The first filter screen is fixed with symmetrically distributed extrusion protrusions that cooperate with the telescopic end of the pneumatic telescopic rod. The outer casing is provided with a dust removal assembly for cleaning the filter screen, the first filter screen, and the second filter screen.

[0007] Furthermore, the dust removal assembly includes a rotating cleaning plate fixedly connected to the rotating ring, a rotating cleaning column rotatably connected to the rotating cleaning plate, a uniformly distributed bristle fixedly connected to the rotating cleaning column, a fixed gear ring fixedly connected inside the housing, a transmission gear meshing with the fixed gear ring fixedly connected to the rotating cleaning column, a symmetrically distributed movable frame slidably connected to the rotating cleaning plate, a third elastic element fixedly connected between the movable frame and the rotating cleaning plate, a uniformly distributed bristle fixedly connected to the movable frame, and a fixed cam fixedly connected to the second filter screen, which cooperates with the symmetrically distributed movable frame.

[0008] Furthermore, the fixed gear ring is located on the side of the rotating cleaning column near the fixed cam, so that the rotation direction of the rotating cleaning column is consistent with the rotation direction of the rotating ring.

[0009] Furthermore, the fixed cam has evenly distributed protrusions on its outer side. The width between two adjacent protrusions on the fixed cam that are closer to the movable frame is greater than the width of the movable frame that is farther away from the fixed cam. The distance between two adjacent movable frames is not an integer multiple of the distance between adjacent protrusions on the fixed cam.

[0010] Furthermore, both the first filter screen and the second filter screen are fixedly connected to a cleaning scraper, which cooperates with the bristles on the rotating cleaning plate and the bristles on the movable frame.

[0011] Furthermore, the wind deflector assembly includes a second electric push rod, which is fixedly connected to one of the support frames on the side away from the housing. A wind deflector plate is fixedly connected to the telescopic end of the second electric push rod. The wind deflector plate is slidably connected to the housing. A wind vane is fixedly connected to the wind deflector plate via a support plate. The height of the wind deflector plate is greater than the height of the housing.

[0012] Furthermore, it also includes a fire extinguishing guide mechanism for assisting fire extinguisher calibration. The fire extinguishing guide mechanism is located on the side of the flame detector away from the outer casing. The fire extinguishing guide mechanism includes a fixing block, which is fixedly connected to the flame detector. A fire extinguishing nozzle is fixedly connected to the fixing block. The fire extinguishing nozzle is connected to the fire extinguishing device via a hose. A sliding ring is rotatably connected to the side of the second filter screen away from the outer casing. The sliding ring is rotatably connected to symmetrically distributed telescopic sliding rods via a rotating shaft. A fixing rod is fixedly connected to the telescopic end of the telescopic sliding rod. A sliding plate is slidably connected to the fixing rod. The sliding plate is rotatably connected to the fire extinguishing nozzle via a rotating shaft. The fire extinguishing nozzle is rotatably connected to symmetrically distributed rotating shafts. The rotating shafts penetrate the fire extinguishing nozzle, and a fourth elastic element is fixedly connected between them. A baffle is fixedly connected to the rotating shaft. The baffle is located inside the fire extinguishing nozzle and the two are sealed together. A connecting rope is fixedly connected between the baffle and the adjacent fixing rod. The connecting rope penetrates the adjacent sliding plate.

[0013] Furthermore, the fire extinguishing nozzle is approximately T-shaped, and the width of the inner wall of the fire extinguishing nozzle is greater than its height, while the height of the baffle is equal to the height of the inner wall of the fire extinguishing nozzle.

[0014] Compared with the prior art, the technical effects achieved by the present invention are as follows: The present invention drives the support rod to rotate through the rotating ring, controls the flame detector to rotate left and right and flip up and down through the first electric rotating shaft and the second electric rotating shaft, and drives the flame detector to move up and down through the climbing mechanism, so that the flame detector can move freely within the detection range, making full use of the monitoring range of the flame detector, monitoring multiple targets in the surrounding area from multiple angles, and improving the utilization rate of the flame detector.

[0015] This invention utilizes the fact that the flame detector needs to rotate frequently during monitoring. When the rotating ring rotates, it synchronously drives the rotating cleaning plate and the pneumatic telescopic rod to rotate. When the flame detector is working, it automatically cleans the filter screen, the first filter screen, the second filter screen, and the end of the flame detector, avoiding the accumulation of dust on the above parts for a long time, which would interfere with the normal operation of the flame detector and the smoke sensor.

[0016] This invention uses a wind vane to detect whether there is wind. When there is wind, the wind deflector moves down to cover the lower part of the filter screen and the first and second filters. The device is then moved up by a climbing mechanism to prevent the wind from carrying dust and causing the smoke sensor to give a false alarm.

[0017] This invention aligns the fire extinguishing nozzle and the flame detector, while simultaneously controlling the fire extinguishing nozzle. This allows the nozzle to spray a larger coverage area when aimed directly below it, and a smaller spray area when flipped upwards to a horizontal position. Simultaneously, the spray distance is increased while the spray area is reduced. This allows the device to adapt to the position of the fire relative to the fire extinguishing nozzle, thereby improving the overall fire extinguishing effect of the fire extinguishing nozzle.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as "upper," "lower," "front," "inner," and "outer" appearing or about to appear in this text are solely for the purposes of the accompanying drawings. Figure 1 This is a reference, and not a specific limitation of the invention.

[0031] Example 1: A fire alarm device with a fire extinguishing structure, such as Figures 1-5As shown, the device includes a housing 101. It is equipped with multiple shared remote control devices and control terminals. By mounting the device on a detection rod, fire detection is achieved, facilitating user operation. The sidewalls of the housing 101 have multiple evenly distributed through holes to increase the area for smoke to enter the housing 101. A filter screen 102 is fixedly connected to each through hole in the housing 101. A first filter screen 103 is fixedly connected to the bottom side of the housing 101. A rotating ring 104 is rotatably connected to the inner side of the first filter screen 103. A second filter screen 105 is fixedly connected to the middle of the inner side of the housing 101 via a support rod. The second filter screen 105 and the first filter screen 103 are in the same plane, and the second filter screen 105 is rotatably connected to the rotating ring 104. A first electric rotating shaft 106, electrically connected to the remote control devices, is rotatably connected to the lower side of the rotating ring 104. A support rod 107 is fixedly connected to the lower side of the first electric rotating shaft 106. When the first electric rotating shaft 106 rotates, it drives the support rod 107 to rotate. The support rod 107 is fixedly connected to a servo motor 108 electrically connected to a remote control device via a bracket. A gear ring is fixedly connected to the lower side of the second filter 105. A transmission gear meshing with the gear ring is fixedly connected to the output shaft of the servo motor 108. When the servo motor 108 is working, it drives the rotating ring 104 to rotate along the gear ring via the transmission gear. A second electric rotating shaft 109 electrically connected to the remote control device is rotatably connected to the lower side of the support rod 107. A flame detector 110 electrically connected to the remote control device is fixedly connected to the second electric rotating shaft 109. When the second electric rotating shaft 109 is working, it drives the flame detector 110 to rotate up and down. A smoke sensor 111 electrically connected to the remote control device is fixedly connected to the upper side of the inner wall of the outer shell 101. A buzzer 112 electrically connected to the remote control device is fixedly connected to the upper part of the outer side of the outer shell 101. A climbing mechanism for climbing and falling is provided on the upper part of the outer side of the outer shell 101. A cleaning mechanism for cleaning itself and the flame detector 110 is provided on the outer shell 101.

[0032] like Figure 3 and Figure 6As shown, the climbing mechanism includes two symmetrically distributed support frames 201, both of which are fixed to the outside of the outer shell 101. Two symmetrically distributed electric friction wheels 202 are mounted on the upper side of the outer shell 101 via brackets. Both electric friction wheels 202 are electrically connected to a remote control device. A sliding block 203 is slidably connected to the support frame 201 via a sliding groove. Two symmetrically distributed clamping blocks 204 are hinged to the middle of the sliding block 203. Adjacent clamping blocks 204 do not directly contact each other, and their middle sections are arc-shaped. A first electric push rod 205, electrically connected to the remote control device, is hinged between the two clamping blocks 204. The first electric push rod 205 is hinged to the adjacent clamping block 204 at a position away from the arc shape. When the first electric push rod 205... When an electric push rod 205 extends, two adjacent clamping blocks 204 rotate along their respective rotating connection points and clamp the detection rod in the middle through their arcs. Two symmetrically distributed fixing plates 206 are fixedly connected to the lower side of the upper sliding block 203. A first elastic element 207 is fixedly connected between the two fixing plates 206 and the lower sliding block 203. The first elastic element 207 is a spring. The clamping blocks 204 on the upper and lower sides clamp alternately, which, together with the electric friction wheel 202, drives the device to rise. Because there is always a set of symmetrical clamping blocks 204 clamping during this process, it is ensured that the device will not slip or rotate during movement. The support frame 201 on the right side is provided with a windproof component for blocking the filter screen 102.

[0033] like Figures 2-5 As shown, the cleaning mechanism includes an L-shaped fixing frame 301, which is fixed to the support rod 107 on the side away from the servo motor 108. A pneumatic telescopic rod 302 is fixed to the upper side of the L-shaped fixing frame 301. A second elastic element 303, which is a spring, is fixed between the telescopic end of the pneumatic telescopic rod 302 and the L-shaped fixing frame 301. A pneumatic piston rod 304 is fixed to the lower side of the L-shaped fixing frame 301. The pneumatic piston rod 304 has two cavities and a piston inside. One of the cavities is connected to the pneumatic telescopic rod 302 through a hose. Another cavity is connected to the outside air. When the pneumatic telescopic rod 302 compresses the gas against the pneumatic piston rod 304, the pneumatic piston rod 304 discharges the gas in the cavity connected to the outside to the flame detector 110 through the piston. Two symmetrically distributed extrusion protrusions 305 are fixed to the lower side of the first filter screen 103. The extrusion protrusions 305 have two inclined surfaces. Both inclined surfaces of the extrusion protrusions 305 are used to extrude the telescopic end of the pneumatic telescopic rod 302. The outer shell 101 is provided with a dust removal assembly that simultaneously cleans the filter screen 102, the first filter screen 103 and the second filter screen 105.

[0034] like Figure 3 , Figure 7 and Figure 8As shown, the dust removal assembly includes a rotating cleaning plate 306, which is fixed to the upper side of the rotating ring 104. A rotating cleaning column 307 is rotatably connected to the side of the rotating cleaning plate 306 near the inner wall of the housing 101. The rotating cleaning column 307 is fixed with evenly distributed bristles for cleaning the filter screen 102. A transmission gear is fixed to the upper side of the rotating cleaning column 307. A fixed gear ring 308 is fixed to the upper side of the inner wall of the housing 101, meshing with the transmission gear on the rotating cleaning column 307. The fixed gear ring 308 is located on the side of the rotating cleaning column 307 near the fixed cam 311. When the rotating cleaning column 307 rotates clockwise following the rotating ring 104, the rotating cleaning column 307 rotates clockwise through the meshing of the transmission gear and the fixed gear ring 308. The rotating cleaning plate 306 is slidably connected to two symmetrically distributed movable frames 309. A third elastic element 310, which is a spring, is fixedly connected between each of the two movable frames 309 and the rotating cleaning plate 306. Evenly distributed bristles are fixedly connected to the lower side of each movable frame 309 for cleaning the first filter screen 103 and the second filter screen 105. The second filter screen 105 is fixedly connected to a component that simultaneously engages with the two movable frames 309. A fixed cam 311 has evenly distributed protrusions on its outer side. The width between two adjacent protrusions on the fixed cam 311 near the movable frame 309 is greater than the width of the movable frame 309 away from the fixed cam 311. Therefore, the movable frame 309 can be inserted into the center of two adjacent protrusions on the fixed cam 311. The distance between two adjacent movable frames 309 is not an integer multiple of the distance between adjacent protrusions on the fixed cam 311. When one movable frame 309 is located at the protrusion point of a protrusion on the fixed cam 311, the other movable frame 309 is positioned... Between two adjacent protrusions on the fixed cam 311, the two movable frames 309 are moved in a staggered manner to increase the effective dust removal area of ​​the two movable frames 309. The first filter screen 103 and the second filter screen 105 are both fixedly connected to cleaning scrapers 312, and the cleaning scraper 312 on the first filter screen 103 is L-shaped. The cleaning scraper 312 is used to move the bristles on the rotating cleaning plate 306 and the movable frame 309 to clean the bristles on the rotating cleaning plate 306 and the movable frame 309, so as to avoid dust accumulation on the bristles on the rotating cleaning plate 306 and the movable frame 309.

[0035] like Figure 2 and Figure 9As shown, the wind deflector assembly includes a second electric push rod 401 electrically connected to a remote control device. The second electric push rod 401 is fixed to the upper side of the right support frame 201. The telescopic end of the second electric push rod 401 faces downward and is fixed to a wind deflector 402. The inner wall of the wind deflector 402 is slidably connected to the outer wall of the outer casing 101. The upper side of the wind deflector 402 is fixed to a wind vane 403 electrically connected to the remote control device via a support plate. When the wind vane 403 detects strong wind, the second electric push rod 401 controls the wind deflector 402 to move downward, blocking the filter screen 102. The height of the wind deflector 402 is greater than the height of the outer casing 101. The lower side of the wind deflector 402 can move downward to a height lower than the lower side of the first filter screen 103, reducing the impact of strong wind on the outer casing 101.

[0036] According to the monitoring plan, staff erected detection rods near important equipment in each substation. Then, they assembled the device at the bottom of the detection rods, positioning the detection rods in the middle of the device. After assembly, staff activated the device via remote control to climb to the top of the detection rods. The specific climbing process is as follows: The remote control extends the upper first electric push rod 205, which presses against the hinged clamping block 204. The two upper clamping blocks 204 rotate along their rotatable connection to clamp the detection rod in the middle. Then, the remote control activates the electric friction wheel 202, which drives the outer casing 101 and its components to climb upwards along the detection rod. The two first elastic elements 207 are compressed and stored, while the upper sliding block 203 moves downwards relative to the adjacent support frame 201 until the first elastic elements 207 are compressed to their maximum extent.

[0037] When the first elastic element 207 is compressed to its maximum extent, the remote control device controls the electric friction wheel 202 to stop moving, and at the same time controls the lower first electric push rod 205 to extend. The lower clamping block 204 rotates according to the same principle and clamps the detection rod in the middle. After the lower clamping block 204 clamps the detection rod, the remote control device controls the upper first electric push rod 205 to shorten. The two upper clamping blocks 204 rotate along their hinge and release the detection rod in the middle. At this time, the two first elastic elements 207 push the upper sliding block 203 to reset, so that the upper sliding block 203 drives its upper components to be repositioned at the top of the adjacent support frame 201. Then the control terminal repeatedly repeats the above process until the device climbs to a height suitable for observing the important equipment of the substation below.

[0038] Once the device has climbed to a suitable observation height, the staff can use a remote control to extend the first electric push rods 205 on both the upper and lower sides simultaneously, causing the clamping blocks 204 on both sides to clamp the detection rod in the middle, thereby fixing the relative position of the outer casing 101. After the staff has installed the device near each set of important equipment in the substation, the installation of the device is complete, and the staff can then control the device to begin its daily early warning work.

[0039] During routine (i.e., when no fire or other abnormal situation occurs) early warning operation, this device automatically repeats the following steps in a loop, except that the smoke sensor 111 remains active:

[0040] The remote control device controls the rotation of the first electric rotating shaft 106, causing the support rod 107 to drive the flame detector 110 to rotate along the first electric rotating shaft 106 as the axis, assisting the flame detector 110 in performing a lateral scan within a range of 30 degrees to the left and right. The remote control device controls the rotation of the second electric rotating shaft 109, causing the flame detector 110 to rotate up and down along the second electric rotating shaft 109 as the axis, assisting the flame detector 110 in performing a longitudinal scan within a range of 30 degrees upward and 50 degrees downward in the horizontal direction. By repeatedly alternating between assisting the flame detector 110 in performing lateral and longitudinal scans, the remote control device expands the scanning range of the flame detector 110, enabling the flame detector 110 to cover important equipment of the substation on one side of the nearby location.

[0041] After the flame detector 110 performs a full scan of the current direction, the remote control device controls the flame detector 110 to return to its initial position and starts the servo motor 108. The output shaft of the servo motor 108 drives the rotating ring 104 to rotate around the gear ring on the lower side of the second filter 105 through gear meshing. The rotating ring 104 drives the flame detector 110 to rotate to face the important substation equipment that has not been scanned on the other side. Then the remote control device turns off the servo motor 108 and controls the flame detector 110 to repeat the above process to perform a full scan of the current important substation equipment.

[0042] After the servo motor 108 drives the flame detector 110 to rotate 360 ​​degrees, the flame detector 110 completes a comprehensive scan of all nearby important equipment. After a certain period of rest, the device reverses its operation and repeats the above scanning process.

[0043] During the operation of the servo motor 108, which drives the flame detector 110 to rotate via the rotating ring 104, the rotating ring 104 synchronously drives the rotating cleaning plate 306 to rotate inside the housing 101. As the rotating cleaning plate 306 rotates with the rotating ring 104, it also drives the components on it to move together. During the rotation of the rotating cleaning column 307 with the rotating ring 104, the transmission gear on it meshes with the fixed gear ring 308, causing the rotating cleaning column 307 to rotate. The direction of rotation of the rotating cleaning column 307 is the same as its direction of movement. That is, when the rotating cleaning column 307 rotates clockwise with the rotating ring 104, the rotating cleaning column 307 also rotates clockwise. When it comes into contact with the filter screen 102, the bristles on the rotating cleaning column 307 quickly clean the filter holes of the filter screen 102, keeping the filter screen 102 clean.

[0044] When the rotating cleaning plate 306 rotates with the rotating ring 104 inside the housing 101, the movable frame 309 is pressed against the fixed cam 311. When the movable frame 309 is located at the gap of the protrusion on the fixed cam 311, the movable frame 309 is pressed against the gap of the protrusion on the fixed cam 311 by the elastic force of the adjacent third elastic element 310. Subsequently, as the movable frame 309 rotates with the rotating cleaning plate 306, it is pressed against the protrusion on the fixed cam 311. When the movable frame 309 moves outward from the fixed cam 311, it compresses the adjacent third elastic element 310. After the movable frame 309 rotates with the rotating cleaning plate 306 and passes the protrusion on the fixed cam 311, the movable frame 309 is reset by the elastic force of the adjacent third elastic element 310, continues to be in contact with the protrusion on the fixed cam 311, and moves towards the center of the fixed cam 311. The above process is repeated as the movable frame 309 rotates with the rotating cleaning plate 306, so that the bristles on the movable frame 309 are... Not only does the circumferential rotation clean the first filter screen 103 and the second filter screen 105, but the moving frame 309 also moves laterally repeatedly, allowing for a more thorough cleaning of the first filter screen 103 and the second filter screen 105. Dust is swept out of the outer casing 101 by the moving frame 309 from the first filter screen 103 and the second filter screen 105. As the moving frame 309 and the rotating cleaning column 307 rotate with the rotating ring 104, they pass over the cleaning scraper 312, and the cleaning scraper 312 interacts with the bristles on the moving frame 309. The bristles on the moving frame 309 and the rotating cleaning column 307 are squeezed together, causing them to bend. After the moving frame 309 and the rotating cleaning column 307 pass the cleaning scraper 312, the bristles on the moving frame 309 and the rotating cleaning column 307 vibrate and return to their original positions. During this process, the bristles on the moving frame 309 and the rotating cleaning column 307 are cleaned, preventing dust accumulation on the bristles on the moving frame 309 and the rotating cleaning column 307.

[0045] Because the rotating ring 104 rotates frequently during the monitoring process, that is, the rotating cleaning plate 306 drives the moving frame 309 and the rotating cleaning column 307 to rotate frequently to carry out cleaning work, so that the filter screen 102, the first filter screen 103 and the second filter screen 105 will not accumulate dust due to not being cleaned for a long time. Even if a small amount of dust is raised, it will not trigger the smoke sensor 111 alarm.

[0046] During the rotation of the flame detector 110 driven by the rotating ring 104, the support rod 107 drives the L-shaped fixing frame 301 to rotate together. When the L-shaped fixing frame 301 drives the pneumatic telescopic rod 302 past the extrusion protrusion 305, the telescopic end of the pneumatic telescopic rod 302 is squeezed by the inclined surface of the extrusion protrusion 305, moves downward and compresses the second elastic element 303. At this time, the gas inside the pneumatic telescopic rod 302 is squeezed into the chamber connected to the pneumatic piston rod 304 through the hose, squeezing the piston inside the pneumatic piston rod 304 to move. The piston movement causes the pneumatic piston rod 302 to move. 4. The space of the chamber connected to the outside becomes smaller, and the gas inside is squeezed out. The ejected gas impacts the surface of the flame detector 110, cleaning the floating dust on it. When the telescopic end of the pneumatic telescopic rod 302 passes the inclined surface of the extrusion protrusion 305, the telescopic end of the pneumatic telescopic rod 302 continues to rotate and moves upward under the reset extrusion of the second elastic element 303. At this time, the pneumatic telescopic rod 302 draws gas from the chamber connected to the pneumatic piston rod 304, so that the piston in the pneumatic piston rod 304 resets, and the chamber connected to the outside of the pneumatic piston rod 304 draws air from the outside to reset.

[0047] When this device is performing routine early warning operations, if strong winds blow due to weather changes, and these winds typically carry a large amount of dust, to reduce the impact of flying dust entering the housing 101 on the smoke sensor 111 alarm, when the wind vane 403 detects strong winds, the remote control device controls the second electric push rod 401 to operate. The telescopic end of the second electric push rod 401 extends downwards, causing the wind deflector 402 to move downwards. After the wind deflector 402 covers the filter screen 102, it continues to move downwards until the lower side of the wind deflector 402 is a certain distance below the lower side of the first filter screen 103. Simultaneously, the remote control device controls this device to climb upwards as described above. The device climbs up the detection rod to a higher position, minimizing dust kicked up from the ground while increasing the monitoring range of the flame detector 110. At this time, the outer casing 101 is vertically enclosed on all sides, reducing the impact of lateral winds. However, when a fire occurs in important equipment in the substation below the device, the strong wind blows the smoke around, making it more difficult for the smoke detector 111 to be triggered. In this case, the device mainly relies on the flame detector 110 to monitor the important equipment in the substation below. When the wind speed decreases, the device automatically resets and resumes the above monitoring process under the control of the remote control device.

[0048] When a fire breaks out, there are two situations: when the ignition point is within the monitoring range of the flame detector 110, and when the ignition point is in the blind zone of the monitoring range of the flame detector 110.

[0049] When the ignition point is within the monitoring range of the flame detector 110, and the smoke detector 111 alarms but the flame detector 110 fails to locate the ignition point, the remote control device controls the buzzer 112 to sound an alarm. At the same time, it controls the flame detector 110 to quickly scan the important equipment of the substation around the smoke detector 111 according to the above working principle to search for the ignition point. Once the ignition point is found, the remote control device notifies the staff and controls the automatic fire extinguishing machine to extinguish the fire.

[0050] If the ignition point is small and produces little smoke, the remote control device will directly control the buzzer 112 to sound an alarm after the flame detector 110 detects the ignition point during routine operation. Subsequently, the remote control device will notify the staff and control the automatic fire extinguishing machine to extinguish the fire.

[0051] When the ignition point is located in the blind spot of the flame detector 110's monitoring range, the remote control device, upon triggering the smoke sensor 111, first controls the flame detector 110 to perform a circumferential full scan. Then, if no ignition point is found, it controls the housing 101 to move its components downwards using the aforementioned principle, changing the height of the flame detector 110 and thus altering its detection range. The flame detector 110 is then controlled to perform a rapid full scan again to search for the ignition point. If the above process is repeated multiple times and no ignition point is found after downward movement, and the smoke sensor 111 de-alarms after downward movement, then the ignition point is not within the monitoring range of the flame detector 110. Subsequently, the remote control device controls the device to move upwards to the initial position to continue fire monitoring.

[0052] When the device repeatedly moves downwards without finding the ignition point, but the smoke sensor 111 does not deactivate its alarm during the movement, it indicates that the ignition point is indeed within the monitoring range of the flame detector 110. At this time, the buzzer 112 will sound an alarm, and the remote control device will simultaneously notify the staff and control the device to reset and continue fire monitoring.

[0053] The remote control device collects information from multiple flame detectors 110 and smoke detectors 111 to comprehensively determine the actual fire range and spread, making it convenient for users to coordinate firefighting resources for firefighting.

[0054] Example 2: Based on Example 1, such as Figure 2 , Figure 3 , Figure 10 and Figure 11As shown, it also includes a fire extinguishing guide mechanism for assisting fire extinguisher calibration. The fire extinguishing guide mechanism is located below the flame detector 110. The fire extinguishing guide mechanism includes a fixing block 501, which is fixed to the lower side of the flame detector 110. A fire extinguishing nozzle 502 is fixed to the fixing block 501. The width of the inner wall of the fire extinguishing nozzle 502 is greater than its height, that is, the fire extinguishing nozzle 502 is flat, which facilitates the modification of the spray area of ​​the fire extinguishing nozzle 502. The fire extinguishing nozzle 502 is connected to the fire extinguishing device through a hose. A sliding ring 503 is rotatably connected to the lower side of the second filter screen 105. The sliding ring 503 is rotatably connected to two symmetrically distributed telescopic sliding rods 504 through a rotating shaft. The telescopic ends of the two telescopic sliding rods 504 are both downward and fixed to a fixing rod 505. The fire extinguishing nozzle 502 is rotatably connected to two symmetrically distributed rotating shafts. Sliding plates 506 are fixed to the rotating shafts on both sides of the fire extinguishing nozzle 502. The sliding plate 506 is slidably connected to the adjacent fixed rod 505. The fire extinguishing nozzle 502 is rotatably connected to two symmetrically distributed rotating shafts 507. Both rotating shafts 507 penetrate the fire extinguishing nozzle 502. A fourth elastic element 508 is fixed between the rotating shaft 507 and the fire extinguishing nozzle 502. The fourth elastic element 508 is set as a torsion spring. A baffle 509 is fixedly connected to the rotating shaft 507 on the inner side of the fire extinguishing nozzle 502. The fire extinguishing nozzle 502 is approximately T-shaped, and the height of the baffle 509 is equal to the height of the inner wall of the fire extinguishing nozzle 502. The two are sealed together to increase the influence of the baffle 509 on the spray area of ​​the fire extinguishing nozzle 502 when it swings. A connecting rope 510 is fixedly connected between the baffle 509 and the adjacent fixed rod 505. The connecting rope 510 penetrates the adjacent sliding plate 506. When the sliding plate 506 moves, it drives the adjacent connecting rope 510 to move together, thereby controlling the swing direction of the two baffles 509.

[0055] When the flame detector 110 swings vertically, the fire extinguishing nozzle 502 swings up and down synchronously with it. Taking the downward swing of the fire extinguishing nozzle 502 as an example, the fire extinguishing nozzle 502 and the flame detector 110 rotate downwards along the second electric rotating shaft 109. At this time, the fire extinguishing nozzle 502 drives the two sliding plates 506 to slide along the fixed rod 505 towards the adjacent telescopic sliding rod 504. The telescopic end of the telescopic sliding rod 504 retracts upwards. At this time, the connecting rope 510 is driven by the sliding plate 506, pulling the adjacent baffle 509 to rotate. The baffle 509 drives the rotating shaft 507 to rotate. As the fire extinguishing nozzle rotates, the adjacent fourth elastic element 508 stores power. At this time, the two adjacent baffles 509 open in opposite directions, increasing the spray area of ​​the fire extinguishing nozzle 502 and enabling it to more effectively cover the fire point below. When the fire extinguishing nozzle 502 swings upward, the two baffles 509 operate in opposite directions according to the above principle and close in opposite directions under the reset action of the adjacent fourth elastic element 508, reducing the spray area of ​​the fire extinguishing nozzle 502. By reducing the spray area of ​​the fire extinguishing nozzle 502, the spray pressure is increased, allowing the fire extinguishing nozzle 502 to more effectively extinguish the fire point relatively far away from itself.

[0056] When the flame detector 110 rotates around the rotating ring 104, the fire extinguishing nozzle 502 drives the two sliding plates 506 and the two fixed rods 505 to rotate together. The two fixed rods 505 drive the two telescopic sliding rods 504 to rotate along the sliding ring 503 and follow the rotating ring 104, so that the fire extinguishing nozzle 502 adapts to the rotation of the rotating ring 104 and does not get stuck.

[0057] When the flame detector 110 rotates via the first electric rotating shaft 106, the fire extinguishing nozzle 502 drives the two fixed rods 505 to rotate together around the first electric rotating shaft 106 via the two sliding plates 506. At this time, the two fixed rods 505 drive the two telescopic sliding rods 504 to rotate around the first electric rotating shaft 106. The two sliding plates 506 slide along the two fixed rods 505, and the two telescopic sliding rods 504 rotate along their rotational connection with the rotating ring 104, causing the rotating ring 104 to rotate at a certain angle to adapt to the rotation of the first electric rotating shaft 106, so that the fire extinguishing nozzle 502 adapts to the rotation of the rotating ring 104 and does not get stuck.

[0058] When a fire occurs, the flame detector 110 detects the ignition point and moves to an angle directly facing the ignition point. Since the fire extinguishing nozzle 502 is fixedly connected to the flame detector 110 and both face the same direction, the staff can remotely activate the fire extinguishing device, causing it to spray ultra-fine extinguishing powder towards the ignition point through the fire extinguishing nozzle 502. At this time, the fire extinguishing nozzle 502 automatically adjusts the spray range and distance according to the location of the ignition point and automatically switches to a more reasonable spray mode for more effective fire extinguishing.
