A first electric rotating shaft 106 electrically connected to the remote control device 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, the first electric rotating shaft 106 drives the support rod 107 to rotate. The support rod 107 is fixedly connected with a servo motor 108 electrically connected to the remote control device through a bracket, a gear ring is fixedly connected to the lower side of the second filter screen 105, and the output shaft of the servo motor 108 is fixedly connected with a transmission gear meshed with the gear ring. When the servo motor 108 is working, the transmission gear drives the rotating ring 104 to rotate along the gear ring. The lower side of the support rod 107 is rotatably connected with a second electric shaft 109 electrically connected to the remote control device, and the second electric shaft 109 is fixedly connected with a flame detector 110 electrically connected to the remote control device. When the second electric shaft 109 is working, the second electric shaft 109 drives the flame detector 110 to flip 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 shell 101, and a buzzer 112 electrically connected to the remote control device is fixedly connected to the upper part of the outer side of the shell 101. A climbing mechanism for climbing and falling is provided on the upper part of the outer side of the shell 101, and a cleaning mechanism for cleaning itself and the flame detector 110 is provided on the shell 101.
[0032] like Figure 3 and Figure 6As shown, the climbing mechanism includes two symmetrically distributed support frames 201, the two support frames 201 are fixed to the outside of the shell 101, and two symmetrically distributed electric friction wheels 202 are installed on the upper side of the shell 101 through a bracket. The two electric friction wheels 202 are electrically connected to the remote control device. The support frames 201 are slidably connected to a sliding block 203 through a sliding groove. The middle part of the sliding block 203 is hinged with two symmetrically distributed clamping blocks 204, and the two adjacent clamping blocks 204 are not in direct contact, and the middle parts of the two are set to be 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 on the adjacent clamping blocks 204 at a position away from the arc shape. When the first electric push rod 205 When an electric push rod 205 is extended, the two adjacent clamping blocks 204 rotate along their respective rotating connections and are clamped toward the central detection long rod through the arcs of the two. Two symmetrically distributed fixed plates 206 are fixedly connected to the lower side of the upper sliding block 203. A first elastic member 207 is fixedly connected between the two fixed plates 206 and the lower sliding block 203. The first elastic member 207 is configured as a spring. The clamping blocks 204 on the upper and lower sides are clamped alternately, and the electric friction wheel 202 is used to drive the device to rise. Because there is always a group of symmetrical clamping blocks 204 clamping during this process, it is ensured that special situations such as slipping and rotation will not occur during the movement of the device. The support frame 201 on the right is provided with a windshield component for shielding the filter 102.
[0033] like Figure 2-Figure 5 As shown, the cleaning mechanism includes an L-shaped fixing frame 301, which is fixed to the side of the support rod 107 away from the servo motor 108, and a pneumatic telescopic rod 302 is fixed to the upper side of the L-shaped fixing frame 301, and a second elastic member 303 is fixed between the telescopic end of the pneumatic telescopic rod 302 and the L-shaped fixing frame 301, and the second elastic member 303 is set as a spring, and a pneumatic piston rod 304 is fixed to the lower side of the L-shaped fixing frame 301, and the pneumatic piston rod 304 is provided with two cavities and a piston, and one of the cavities is connected to the pneumatic telescopic rod 302 through a hose. The other cavity is connected to the outside air. When the pneumatic telescopic rod 302 squeezes the gas toward 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 103. The extrusion protrusions 305 are provided with two inclined surfaces. The two inclined surfaces of the extrusion protrusions 305 are both used to squeeze the telescopic end of the pneumatic telescopic rod 302. The outer shell 101 is provided with a dust removal component for simultaneously cleaning the filter 102, the first filter 103 and the second filter 105.
[0034] like Figure 3 , Figure 7 and Figure 8As shown, the dust removal assembly includes a rotating cleaning plate 306, which is fixedly connected to the upper side of the rotating ring 104. The rotating cleaning plate 306 is rotatably connected to a rotating cleaning column 307 on one side close to the inner wall of the housing 101. The rotating cleaning column 307 is fixedly connected with evenly distributed bristles for cleaning the filter 102. A transmission gear is fixedly connected to the upper side of the rotating cleaning column 307. A fixed gear ring 308 meshing with the transmission gear on the rotating cleaning column 307 is fixedly connected to the upper side of the inner wall of the housing 101. The fixed gear ring 308 is located on the side of the rotating cleaning column 307 close to 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, and the rotating cleaning plate 306 is slidably connected to two symmetrically distributed moving frames 309, and the two moving frames 309 and the rotating cleaning plate 306 are fixedly connected with a third elastic member 310, and the third elastic member 310 is set as a spring. The lower side of the moving frame 309 is fixedly connected with uniformly distributed bristles for cleaning the first filter screen 103 and the second filter screen 105, and the second filter screen 105 is fixedly connected with a brush that cooperates with the two moving frames 309 at the same time. The fixed cam 311 has evenly distributed protrusions on the outer side of the fixed cam 311. The width between two adjacent protrusions on the fixed cam 311 close to 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 the two adjacent protrusions on the fixed cam 311, and the distance between the two adjacent movable frames 309 is not equal to an integer multiple of the distance between the adjacent protrusions on the fixed cam 311. When one of the movable frames 309 is located at the protrusion point of a protrusion on the fixed cam 311, the other movable frame 309 is located at the protrusion point of a protrusion on the fixed cam 311. The two movable frames 309 are moved in an offset manner between two adjacent protrusions on the fixed cam 311 to increase the effective dust sweeping area of the two movable frames 309. The first filter 103 and the second filter 105 are both fixedly connected with a cleaning scraper 312, and the cleaning scraper 312 on the first filter 103 is L-shaped. The cleaning scraper 312 is used to move the bristles on the rotating cleaning plate 306 and the bristles on the movable frame 309 to clean the bristles on the rotating cleaning plate 306 and the bristles on the movable frame 309 to avoid dust accumulation on the bristles on the rotating cleaning plate 306 and the bristles on the movable frame 309.
[0035] like Figure 2 and Fig. 9As shown, the windshield assembly includes a second electric push rod 401 electrically connected to the remote control device, the second electric push rod 401 is fixedly connected to the upper side of the right support frame 201, the telescopic end of the second electric push rod 401 is downward and fixedly connected to a windshield 402, the inner wall of the windshield 402 is slidably connected to the outer wall of the outer shell 101, and the upper side of the windshield 402 is fixedly connected to a weather vane 403 electrically connected to the remote control device through a support plate. When the wind vane 403 detects strong wind, the second electric push rod 401 controls the windshield 402 to move downward to block the filter 102. The height of the windshield 402 is greater than the height of the outer shell 101, and the lower side of the windshield 402 can move downward to a height lower than the lower side of the first filter 103, thereby reducing the impact of strong wind on the outer shell 101.
[0036] The staff erects a detection pole near each important equipment of the substation according to the monitoring plan, and then assembles the device at the bottom of the detection pole so that the detection pole is located in the middle of the device. After the assembly is completed, the staff starts the device through the remote control device to climb to the upper end of the detection pole. The specific crawling process is as follows: the remote control device controls the extension of the first electric push rod 205 on the upper side, and the first electric push rod 205 on the upper side extends to squeeze the clamping block 204 hinged thereto, and the two clamping blocks 204 on the upper side rotate along their rotating connection to clamp the middle of the detection pole, and then the remote control device starts the electric friction wheel 202, and the electric friction wheel 202 drives the housing 101 and its components to crawl upward along the detection pole, and the two first elastic members 207 are compressed and stored, and at the same time, the upper sliding block 203 moves downward relative to the adjacent support frame 201 until the first elastic member 207 is compressed to the maximum extent.
[0037] When the first elastic member 207 is compressed to the maximum extent, the remote control device controls the electric friction wheel 202 to stop moving, and at the same time controls the first electric push rod 205 on the lower side to extend, and the lower clamping block 204 rotates and clamps the middle detection long rod according to the same principle as mentioned above. After the lower clamping block 204 clamps the detection long rod, the remote control device controls the upper first electric push rod 205 to shorten, and the two upper clamping blocks 204 rotate along their hinges and loosen the middle detection long rod. At this time, the two first elastic members 207 push the upper sliding block 203 to reset, so that the upper sliding block 203 drives the components on it to be re-located at the top of the adjacent support frame 201, and then the control terminal repeatedly repeats the above process until the device climbs to a height suitable for observing important equipment in the substation below.
[0038] When the device climbs to a suitable observation height, the staff controls the first electric push rods 205 on the upper and lower sides to extend simultaneously through the remote control device, so that the clamping blocks 204 on the upper and lower sides simultaneously clamp the middle detection long rod, so as to fix the relative position of the shell 101. When the staff has installed the device near each group of important equipment in the substation, the installation of the device is completed, and the staff controls the device to start daily early warning work.
[0039] During the daily warning operation of the device (i.e. when no abnormal situation such as fire occurs), the smoke sensor 111 is always in an activated state, and the following steps are automatically repeated:
[0040] The remote control device controls the rotation of the first electric shaft 106 so that the support rod 107 drives the flame detector 110 to rotate along the first electric shaft 106 as the axis, and the auxiliary flame detector 110 performs a horizontal scan within a range of 30 degrees to the left and right. The remote control device controls the rotation of the second electric shaft 109 so that the flame detector 110 flips up and down along the second electric shaft 109 as the axis, and the auxiliary flame detector 110 performs a longitudinal scan within a range of 30 degrees upward in the horizontal direction and 50 degrees downward in the horizontal direction. The remote control device expands the scanning range of the flame detector 110 by repeatedly and alternately repeating the process of the auxiliary flame detector 110 performing horizontal scanning and longitudinal scanning, so that the scanning range of the flame detector 110 covers important equipment of the substation on one side at a close distance.
[0041] After the flame detector 110 performs a comprehensive scan of the current direction, the remote control device controls the flame detector 110 to restore the 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 transmission. The rotating ring 104 drives the flame detector 110 to rotate to the direction facing the important substation equipment on the other side that has not been scanned. 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 comprehensive scan of the important equipment in the current substation.
[0042] When the servo motor 108 drives the flame detector 110 to rotate 360 degrees, the flame detector 110 completes a comprehensive scan of all important equipment nearby. After a certain period of rest, the device runs in reverse to repeat the above scanning process.
[0043] When the servo motor 108 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. The rotating cleaning plate 306 drives the components thereon to move together with the rotating ring 104. The rotating cleaning column 307 rotates with the rotating ring 104, and the transmission gear thereon meshes with the fixed gear ring 308, so that the rotating cleaning column 307 rotates, and the rotation direction of the rotating cleaning column 307 is the same as its movement direction, that is, when the rotating cleaning column 307 rotates clockwise with the rotating ring 104, the rotating cleaning column 307 rotates clockwise at the same time, so that when it contacts the filter 102, the bristles on the rotating cleaning column 307 quickly clean the filter holes of the filter 102 to keep the filter 102 clean.
[0044] When the rotating cleaning plate 306 follows the rotating ring 104 to rotate inside the shell 101, the movable frame 309 is squeezed and matched with the fixed cam 311. When the movable frame 309 is located at the gap between the protrusions on the fixed cam 311, the movable frame 309 is subjected to the elastic force of the adjacent third elastic member 310 and is squeezed to the gap between the protrusions on the fixed cam 311. Subsequently, in the process of the movable frame 309 following the rotation of the rotating cleaning plate 306, the movable frame 309 is squeezed and matched with the protrusions on the fixed cam 311. When the movable frame 309 moves toward the outside of the fixed cam 311, the adjacent third elastic member 310 is compressed. After the movable frame 309 follows the rotation of the rotating cleaning plate 306 and passes through the protrusions on the fixed cam 311, the movable frame 309 is reset by the elastic action of the adjacent third elastic member 310, and continues to fit with the protrusions on the fixed cam 311 and moves toward the center direction of the fixed cam 311. The above process is repeated when the movable frame 309 follows the rotation of the rotating cleaning plate 306, so that the bristles on the movable frame 309 The first filter screen 103 and the second filter screen 105 are not only cleaned by the circumferential rotation, but also the movable frame 309 is repeatedly moved horizontally, so that the movable frame 309 can clean the first filter screen 103 and the second filter screen 105 more fully. The dust is swept out of the housing 101 from the first filter screen 103 and the second filter screen 105 by the movable frame 309. When the movable frame 309 and the rotating cleaning column 307 rotate with the rotating ring 104, they pass through the cleaning scraper 312, and the cleaning scraper 312 and the bristles on the movable frame 309 are The bristles on the movable frame 309 and the rotating cleaning column 307 are squeezed against each other, causing the bristles on the movable frame 309 and the rotating cleaning column 307 to bend, and after the movable frame 309 and the rotating cleaning column 307 pass through the cleaning scraper 312, the bristles on the movable frame 309 and the rotating cleaning column 307 are shaken and reset, and in this process the bristles on the movable frame 309 and the rotating cleaning column 307 are cleaned, thereby preventing the bristles on the movable frame 309 and the rotating cleaning column 307 from accumulating dust.
[0045] Because the rotating ring 104 rotates frequently during the monitoring process, that is, the rotating cleaning plate 306 drives the movable frame 309 and the rotating cleaning column 307 to rotate frequently for cleaning, so that the filter 102, the first filter 103 and the second filter 105 will not accumulate dust due to being not cleaned for a long time. Even if a small amount of dust floats, the smoke sensor 111 will not be mistakenly triggered to alarm.
[0046] In the process of the rotating ring 104 driving the flame detector 110 to rotate, 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 to pass through 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 member 303. At this time, the gas in the pneumatic telescopic rod 302 is squeezed into the chamber connected to the pneumatic piston rod 304 and the pneumatic telescopic rod 302 through the hose, squeezing the piston in the pneumatic piston rod 304 to move, and the movement of the piston causes the pneumatic piston rod 302 to move. The space of the chamber connected to the outside world becomes smaller, and the gas therein is squeezed and ejected, and the ejected gas impacts the surface of the flame detector 110 to clean the dust thereon. After the telescopic end of the pneumatic telescopic rod 302 passes the inclined surface of the extrusion convex block 305, the telescopic end of the pneumatic telescopic rod 302 continues to rotate and moves upward under the reset squeeze of the second elastic member 303. At this time, the pneumatic telescopic rod 302 extracts gas from the chamber connected to the pneumatic piston rod 304, so that the piston in the pneumatic piston rod 304 is reset, and the chamber connected to the pneumatic piston rod 304 and the outside world is re-absorbed from the outside world to reset.
[0047] When the device is performing daily warning work, the weather changes and strong winds blow. Because strong winds usually carry a lot of dust, in order 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 work, and the telescopic end of the second electric push rod 401 extends downward to move the wind shield 402 downward. After the wind shield 402 blocks the filter 102, it continues to move downward until the lower side of the wind shield 402 is a certain distance lower than the lower side of the first filter 103. At the same time, the remote control device controls the device to climb according to the above principle. The device climbs up to a higher position along the detection pole to avoid dust raised from the ground to the greatest extent while increasing the monitoring range of the flame detector 110. At this time, the outer shell 101 is in a closed state in the vertical direction on all sides to reduce the influence of lateral wind. However, when a fire occurs in important equipment of the substation below the device, the smoke is blown away by strong wind, making it more difficult for the smoke to trigger the smoke sensor 111. At this time, the device mainly relies on the flame detector 110 to monitor the important equipment of the substation below. When the wind speed becomes smaller, 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 fire point is located within the monitoring range of the flame detector 110, and when the fire point is located in a blind spot of the monitoring range of the flame detector 110.
[0049] When the fire point is within the monitoring range of the flame detector 110, the smoke sensor 111 alarms but the flame detector 110 cannot find the fire point, the remote control device controls the buzzer 112 to alarm, and at the same time controls the flame detector 110 to quickly scan the important equipment of the substation around the smoke sensor 111 according to the above working principle, searching for the fire point. Once found, the remote control device notifies the staff and controls the automatic fire extinguishing machine to extinguish the fire.
[0050] If the fire point is small and produces less smoke, the remote control device directly controls the buzzer 112 to alarm after discovering the fire point during the daily operation of the flame detector 110. The remote control device then notifies the staff and controls the automatic fire extinguishing machine to extinguish the fire.
[0051] When the fire point is located in the blind spot of the monitoring range of the flame detector 110, the remote control device controls the flame detector 110 to perform a circumferential full scan when the smoke sensor 111 is triggered. Then, if no fire point is found, the housing 101 is controlled by the above principle to drive the components thereon to move downward, thereby changing the height of the flame detector 110, thereby changing the detection range of the flame detector 110, and the flame detector 110 is controlled again to perform a quick and full scan to search for the fire point. When the above process is repeated for multiple downward movements and no fire point is found, and the smoke sensor 111 releases the alarm after moving downward, the fire point is not located within the monitoring range of the flame detector 110 here, and then the remote control device controls the device to move upward to the initial position to continue fire monitoring.
[0052] When the device repeats the above process and moves downward for several times without finding the fire point, the smoke sensor 111 never stops the alarm during the movement, indicating that the fire point is indeed located within the monitoring range of the flame detector 110. At this time, the buzzer 112 sounds an alarm, and the remote control device notifies the staff and controls the device to reset and continue fire monitoring.
[0053] The remote control device collects information from multiple flame detectors 110 and smoke sensors 111 to comprehensively determine the actual fire scope and spread, making it convenient for users to comprehensively dispatch fire-fighting resources to extinguish the fire.
[0054] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 3 , Fig.10 and Fig.11As shown, a fire extinguishing guide mechanism for assisting the calibration of the fire extinguisher is also included. The fire extinguishing guide mechanism is arranged on the lower side of the flame detector 110. The fire extinguishing guide mechanism includes a fixed block 501. The fixed block 501 is fixedly connected to the lower side of the flame detector 110. The fixed block 501 is fixedly connected to a fire extinguishing nozzle 502. The inner wall width of the fire extinguishing nozzle 502 is greater than the inner wall height, that is, the fire extinguishing nozzle 502 is flat, which is convenient for changing the spraying area of the fire extinguishing nozzle 502. The fire extinguishing nozzle 502 is connected to the fire extinguishing device through a hose. The lower side of the second filter screen 105 is rotatably connected to a sliding ring 503. The sliding ring 503 is rotatably connected to two symmetrically distributed telescopic slide rods 504 through a rotating shaft. The telescopic ends of the two telescopic slide rods 504 are downward and fixedly connected to the fixed rod 505. The fire extinguishing nozzle 502 is rotatably connected to two symmetrically distributed rotating shafts, and the rotating shafts on both sides of the fire extinguishing nozzle 502 are fixedly connected to sliding plates 506. The sliding plate 506 is slidably connected to the adjacent fixed rod 505, and the fire sprinkler 502 is rotatably connected to two symmetrically distributed rotating shafts 507, and the two rotating shafts 507 both penetrate the fire sprinkler 502. A fourth elastic member 508 is fixedly connected between the rotating shaft 507 and the fire sprinkler 502, and the fourth elastic member 508 is configured as a torsion spring. The rotating shaft 507 is fixedly connected to a baffle 509 on the inner side of the fire sprinkler 502. The fire sprinkler 502 is approximately T-shaped, and the height of the baffle 509 is equal to the height of the inner wall of the fire sprinkler 502 and the two are sealed to increase the influence of the baffle 509 on the spraying area of the fire sprinkler 502 when it swings. A connecting rope 510 is fixedly connected between the baffle 509 and the adjacent fixed rod 505, and 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 swinging direction of the two baffles 509.
[0055] When the flame detector 110 swings in the vertical direction, the fire extinguishing nozzle 502 swings up and down synchronously with the flame detector 110. Taking the downward swing of the fire extinguishing nozzle 502 as an example, the fire extinguishing nozzle 502 and the flame detector 110 flip downward along the second electric rotating shaft 109 as the axis. At this time, the fire extinguishing nozzle 502 drives the two sliding plates 506 to slide along the fixed rod 505 toward the direction of the adjacent telescopic sliding rod 504, and the telescopic end of the telescopic sliding rod 504 retracts upward. At this time, the connecting rope 510 is driven by the sliding plate 506 to pull the adjacent baffle plate 509 to rotate, and the baffle plate 509 drives the rotating shaft 507 to rotate. When the fire extinguishing nozzle 502 is swung upward, the two baffles 509 operate in the opposite direction according to the above principle, and are closed towards each other under the action of the reset of the adjacent fourth elastic member 508, so that the spraying area of the fire extinguishing nozzle 502 becomes smaller. By reducing the spraying area of the fire extinguishing nozzle 502, its spraying pressure is increased, so that the fire extinguishing nozzle 502 can be more effectively aimed at the fire point that is relatively far away from itself for extinguishing.
[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, and the two fixed rods 505 drive the two telescopic sliding rods 504 to rotate along the sliding ring 503 following the rotating ring 104, so that the fire extinguishing nozzle 502 adapts to the rotation of the rotating ring 104 and will not get stuck.
[0057] When the flame detector 110 rotates by the first electric shaft 106, the fire extinguishing nozzle 502 drives the two fixed rods 505 to rotate together with the first electric shaft 106 through the two sliding plates 506. At this time, the two fixed rods 505 drive the two telescopic slide rods 504 to rotate with the first electric shaft 106 as the axis. The two sliding plates 506 slide along the two fixed rods 505, and the two telescopic slide rods 504 rotate along the rotating connection between them and the rotating ring 104, and make the rotating ring 104 rotate a certain angle to adapt to the rotation of the first electric shaft 106, so that the fire extinguishing nozzle 502 adapts to the rotation of the rotating ring 104 and will not get stuck.
[0058] When a fire occurs, the flame detector 110 finds the fire point and moves to an angle facing the fire point. Since the fire extinguishing nozzle 502 is fixedly connected to the flame detector 110 and the two face the same direction, the staff remotely controls the fire extinguishing device to directly start the fire extinguishing device, so that the fire extinguishing nozzle 502 sprays ultra-fine fire extinguishing powder toward the fire point. At this time, the fire extinguishing nozzle 502 automatically adjusts the spraying range and distance according to the position of the fire point and automatically switches to a more reasonable spraying mode, so as to carry out more effective fire extinguishing.
