Description

Technical Field

[0001] The present invention relates to the technical field of mountain fire monitoring, and in particular to a mountain fire monitoring device based on infrared thermal imaging technology. Background Art

[0002] Forest fire prevention is the key task of forest protection. The causes of forest fires are mostly various human factors or abnormal weather that lead to accidental damage to power lines. Therefore, areas near mountain villages and areas near the installation of power lines are key areas for monitoring forest fires. The existing way to monitor forest fires is usually to use infrared thermal imagers. During use, existing infrared thermal imagers need to be placed at high places to ensure a wide field of view, so as to monitor more places. However, where there are human traces, there are usually also a lot of white garbage. White garbage can easily be blown into the sky by strong winds and eventually hang on the infrared thermal imagers installed at high places, causing the infrared thermal imagers to be unable to monitor the mountains and forests normally, which can easily delay the time to discover fires. Existing infrared thermal imagers are difficult to automatically peel off white garbage, and they cannot block flying white garbage. When white garbage hangs on the infrared thermal imager, the inspection personnel can only go to the installation site to remove the white garbage that blocks the infrared thermal imager's line of sight, resulting in additional workload for the inspection personnel.

The convex surface of the wind blocking shell 6 is fixedly connected with two equally distributed wind guide shells 61, which are arc-shaped plates, and the opening directions of the two wind guide shells 61 are facing the same side, which is used to ensure that the wind blocking shell 6 can still be blown by the wind when the convex surface is exposed to wind. A support plate 7 is fixedly connected to the left side of the second rotating ring 5, and a sliding frame 8 is slidably connected to the left side of the support plate 7. The sliding frame 8 and the support plate 7 are both provided with slides of equal width. The slides on the sliding frame 8 and the slides on the support plate 7 are slidably connected with the first baffle 9. When the first baffle 9 moves horizontally, the first baffle 9 drives the sliding frame 8 to move together, and the slides on the sliding frame 8 are staggered with the slides on the support plate 7. The first baffle 9 is a rectangle, and its left side area is smaller than its front and rear side areas, which is used to reduce the area affected by wind and reduce the area blocked by the infrared thermal imaging camera 3. The first rotating ring 4 is provided with a locking mechanism to lock itself.

[0035] refer to Figure 1 and Figure 4-Figure 7The locking mechanism includes a fixed plate 10 fixedly connected to the lower middle side of the first rotating ring 4, a rotating shaft 11 is rotatably connected to the left side of the fixed plate 10, a turbofan 12 and a fixed ring 13 are fixedly connected to the left side of the rotating shaft 11, the fixed ring 13 is fixedly connected to symmetrically distributed support rods, the fixed ring 13 is slidably connected to two weight blocks 14 through two support rods, the rotating shaft 11 is slidably connected to a sliding ring 15, a first steel wire rope 151 is fixedly connected between the weight block 14 and the sliding ring 15, the first steel wire rope 151 penetrates the fixed ring 13, when the weight block 14 is moved by centrifugal force, the weight block 14 pulls the sliding ring 15 to move to the left through the first steel wire rope 151, so as to achieve the purpose of unlocking the first rotating ring 4 and the second rotating ring 5, a second elastic member 152 is installed between the sliding ring 15 and the fixed plate 10, the second elastic member 152 Component 152 is a tension spring, and the outer side of the sliding ring 15 is rotatably connected to a moving plate 16. When the sliding ring 15 moves, the moving plate 16 moves along with the sliding ring 15. A moving ring 17 is fixedly connected to the upper side of the moving plate 16. The moving ring 17 is slidably connected to the first rotating ring 4. A limiting block 171 is fixedly connected to the right side of the moving ring 17. The frame 1 is provided with grooves evenly distributed in the circumferential direction. The grooves on the frame 1 are used to cooperate with the limiting block 171 to ensure that the first rotating ring 4 and the frame 1 remain in a relatively fixed state when in the switching state. The first rotating ring 4 and the second rotating ring 5 are both provided with grooves on the opposite sides, and the grooves of the two are combined into a limiting groove. When the limiting block 171 is inserted into the limiting groove, the first rotating ring 4 and the second rotating ring 5 cannot produce relative rotation, and the second rotating ring 5 is provided with a telescopic component.

[0036] refer to Figure 1 and Figure 8-Figure 11The telescopic assembly includes a rotating gear 18 rotatably connected to the lower side of the first rotating ring 4, the rotating gear 18 is provided with a slide groove, and the limit block 171 is provided with a convex column that is squeezed and matched with the slide groove on the rotating gear 18. The inner diameter of the front side of the rotating gear 18 gradually increases to avoid the lateral movement of the moving plate 16. The rotation angle of the slide groove on the rotating gear 18 is greater than 90°. When the limit block 171 moves, the limit block 171 squeezes the rotating gear 18 through the convex column to rotate. The first reel 19 is rotatably connected to the second rotating ring 5. The first reel 19 is fixedly connected to the transmission gear. The first reel 19 is connected to the rotating gear through the transmission gear. 18 is meshed, the support plate 7 is rotatably connected to the second reel 20 connected to the first reel 19 through a rope through a rotating shaft, when the first reel 19 rotates, the first reel 19 pulls the second reel 20 to rotate through the rope, the lower side of the support plate 7 is rotatably connected to the third reel 21 through a rotating shaft, a third elastic member 211 is installed between the third reel 21 and the second reel 20, the third elastic member 211 is a torsion spring, a fourth elastic member 91 is installed between the first baffle plate 9 and the sliding frame 8, the fourth elastic member 91 is a tension spring, the upper side of the first baffle plate 9 is rotatably connected to the rotating wheel 92, and the upper side of the rotating wheel 92 is fixedly connected to the second The fence 93, the slideway on the sliding frame 8 and the slideway on the support plate 7 are all slidably connected to the second fence 93. The shape of the second fence 93 is the same as that of the first fence 9. A second steel wire rope 212 is fixedly connected between the second fence 93 and the third reel 21. The elastic coefficient of the third elastic member 211 is greater than the elastic coefficient of the fourth elastic member 91. When the second reel 20 pulls the third reel 21 to rotate through the third elastic member 211, and the fourth elastic member 91 reels the second steel wire rope 212 to move the first fence 9 downward, the fourth elastic member 91 cannot prevent the first fence 9 from moving downward by its own elastic force. The support plate 7 is provided with a second elastic member 212 fixedly connected to the first reel 21. The baffle plate 9 has through holes with the same cross-sectional shape. When the first baffle plate 9 and the second baffle plate 93 slide in the through holes on the support plate 7, the first baffle plate 9 and the second baffle plate 93 are horizontally limited by the support plate 7. When the first baffle plate 9 and the second baffle plate 93 are separated from the horizontal limiting relationship with the support plate 7, when the first baffle plate 9 moves horizontally, the first baffle plate 9 is staggered with the through holes on the support plate 7, and the first baffle plate 9 is limited in the vertical direction of the support plate 7. The second steel wire rope 212 passes through the through holes on the support plate 7. The first baffle plate 9 is provided with an auxiliary interception component to assist in intercepting floating objects, and the support plate 7 is provided with a rotating component to deflect the second baffle plate 93.

[0037] refer to Fig.10 and Fig.11The auxiliary intercepting component includes a first pneumatic push rod 22 fixedly connected to the lower side of the first baffle 9, the telescopic end of the first pneumatic push rod 22 is squeezed and matched with the support plate 7, the first baffle 9, the rotating wheel 92, the second baffle 93 and the first pneumatic push rod 22 are fixedly connected and connected with a ventilation pipe 221, and the first baffle 9 and the second baffle 9 are both provided with uniformly distributed elastic air bags 23, the elastic air bags 23 are fixedly connected and connected with the ventilation pipe 221, and the upper side of the elastic air bags 23 is fixedly connected with spikes, which are inclined upward from the horizontal direction to facilitate the hanging of white garbage. The spikes on the elastic air bags 23 are slidably connected with the first baffle 9. When the telescopic end of the first pneumatic push rod 22 retracts, the gas therein rushes into all the elastic air bags 23, and the elastic air bags 23 expand to make the adjacent spikes protrude outward.

[0038] refer to Fig.12 : The rotating component includes a wedge block 24 fixed to the left side of the support plate 7, and the first baffle plate 9 is slidably connected to the extrusion column 25 which slides up and down. When the first baffle plate 9 drives the extrusion column 25 to move horizontally, the extrusion column 25 is squeezed by the wedge block 24 and moves upward. The rotating wheel 92 is provided with a spiral groove. When the extrusion column 25 moves upward, it squeezes the spiral groove on the rotating wheel 92 to make the rotating wheel 92 rotate 90°. A fifth elastic member 251 is installed between the extrusion column 25 and the first baffle plate 9, and the fifth elastic member 251 is a tension spring.

[0039] The staff installed the device on a high tower in the forest, and rotated the pan / tilt 2 to drive the infrared thermal imaging camera 3 to rotate to monitor the forest and nearby areas 24 hours a day to prevent the occurrence of fire.

[0040] When the wind blows, there are the following two situations: when the surface of the wind blocking shell 6 that is blown by the wind is concave, the wind blocking shell 6 is affected by the wind force, driving the second rotating ring 5 to gradually rotate in the direction of the wind force until the wind blocking shell 6 rotates to the leeward side. At this time, the wind blocking shell 6 and the second rotating ring 5 remain stationary.

[0041] When the surface of the wind-blocking shell 6 that is blown by the wind is convex, it is difficult for the wind to directly drive the wind-blocking shell 6 to rotate. The wind gradually blows into the concave surface of the wind-guiding shell 61. The concave surface of the wind-guiding shell 61 is affected by the wind force, driving the wind-blocking shell 6 to gradually rotate toward the leeward side until the wind-blocking shell 6 rotates to its concave surface that is blown by the wind. Then the wind-blocking shell 6 moves according to the same principle as mentioned above, and finally stops at the leeward side as well, so as to determine the wind direction.

[0042] In the initial state, the limit block 171 cooperates with the first rotating ring 4 and the second rotating ring 5 at the same time. In the process of the wind blocking shell 6 driving the second rotating ring 5 to rotate, the second rotating ring 5 drives the first rotating ring 4 to rotate together through the limit block 171. Therefore, when the wind blocking shell 6 stops rotating, the first rotating ring 4 drives the adjacent components to be located in the upwind direction through the fixed plate 10, and the second rotating ring 5 drives the adjacent components to be located in the upwind direction through the support plate 7. In the initial state, the first baffle plate 9 and the second baffle plate 93 are both located below the sliding frame 8, the fourth elastic member 91 is in a stretched and force-accumulating state, and the second steel wire rope 212 is in a state of being wound up by the third reel 21. At this time, the turbofan 12 is facing the wind, and the turbofan 12 begins to drive the rotating shaft 11 and the adjacent components to rotate under the action of wind force.

[0043] When the wind force is low and the turbofan 12 rotates slowly, the sum of the centrifugal forces acting on the two weight blocks 14 is smaller than the elastic force of the second elastic member 152 , and the second elastic member 152 and the sliding ring 15 do not move.

[0044] When the wind force gradually increases, the centrifugal force on the weight block 14 gradually increases to be greater than the elastic force of the second elastic member 152, and the weight block 14 moves in the direction away from the rotating shaft 11. The two weight blocks 14 jointly pull the sliding ring 15 to the upwind side through the adjacent first steel wire rope 151, and the second elastic member 152 stretches and accumulates force. The sliding ring 15 drives the moving ring 17 to move synchronously through the moving plate 16, and the moving ring 17 drives the limit block 171 to move synchronously. In this process, the limit block 171 gradually releases the limit on the upper limit grooves of the first rotating ring 4 and the second rotating ring 5. When the limit block 171 is separated from the upper limit grooves of the first rotating ring 4 and the second rotating ring 5, the limit block 171 is gradually inserted into the adjacent grooves on the frame 1. At this time, the first rotating ring 4 and the frame 1 are in a relatively fixed state, and when the second rotating ring 5 rotates, it no longer drives the first rotating ring 4 to rotate together.

[0045] When the limit block 171 moves following the moving ring 17, the limit block 171 squeezes the sliding groove on the rotating gear 18 through the convex column, thereby driving the rotating gear 18 to rotate. When the limit block 171 stops moving, the limit block 171 keeps the rotating gear 18 in a relatively fixed state through the convex column. When the rotating gear 18 rotates, the wind shield 6 is acted upon by the wind force to keep the second rotating ring 5 stationary. The rotating gear 18 drives the first reel 19 and the transmission gear thereon to rotate together. The rotation of the first reel 19 drives the second reel 20 to rotate. The second reel 20 drives the first reel 19 to rotate through the third elastic member 211. The third winding wheel 21 rotates, and the second steel wire rope 212 is released when the third winding wheel 21 rotates. At this time, the first baffle 9 moves upward under the action of the fourth elastic member 91, and the first baffle 9 drives the adjacent components to move upward together. When the rotating gear 18 stops rotating, the first baffle 9 stops moving upward, and the first baffle 9 just moves to a position where the through hole on the support plate 7 is out of lateral limit cooperation, and the fourth elastic member 91 is completely released and no elastic force is stored. At this time, the first baffle 9 and the second baffle 93 block the upwind side of the infrared thermal imaging camera 3 to block the white garbage blown by the wind.

[0046] When the first baffle 9 stops moving upward, because the wind-receiving areas of the first baffle 9 and the second baffle 93 are small, the wind force received by the first baffle 9 is smaller than the elastic force of the fifth elastic member 251, and when facing the lens of the infrared thermal imaging camera 3, the shielding area of ​​the infrared thermal imaging camera 3 is very small. Therefore, when the infrared thermal imaging camera 3 rotates for patrol, the wide-angle field of view of the infrared thermal imaging camera 3 is not affected.

[0047] During the upward movement of the first baffle 9, the first baffle 9 drives the first pneumatic push rod 22 to move upward together. When the first baffle 9 is close to the support plate 7, the telescopic end of the first pneumatic push rod 22 first contacts the support plate 7, and then the telescopic end of the first pneumatic push rod 22 is squeezed by the support plate 7 and gradually compressed. The gas in the first pneumatic push rod 22 flows into all the elastic air bags 23 through the ventilation pipe 221. The expansion of the elastic air bags 23 drives the spikes thereon to protrude out of the outer surfaces of the first baffle 9 and the second baffle 93, making it convenient for the white garbage floating in the wind to be hung on the outside of the first baffle 9 and the second baffle 93.

[0048] During the operation of the infrared thermal imaging camera 3, when the white garbage floats in the air with the wind and approaches the infrared thermal imaging camera 3, the white garbage first contacts the first baffle 9 and the second baffle 93. At this time, the white garbage is hooked by the spikes on the first baffle 9 and the second baffle 93 and cannot continue to float with the wind, thereby ensuring that the white garbage will not get hung on the infrared thermal imaging camera 3.

[0049] When the white garbage is hooked by the spikes, although the white garbage can no longer float with the wind, it is still affected by a large wind force. The white garbage applies a pulling force to the first baffle 9 and the second baffle 93 in the direction of the infrared thermal imaging camera 3 through the spikes, so that the first baffle 9 drives the extrusion column 25 to move in the direction of the wedge block 24. When the pulling force on the first baffle 9 and the second baffle 93 is greater than the pulling force of the fifth elastic member 251 on the extrusion column 25, the first baffle 9 and the second baffle 93 move toward the infrared thermal imaging camera 3 through the sliding frame 8, and the extrusion column 25 is squeezed by the wedge block 24 and moves upward, and the fifth elastic member 251 is stretched by the force. When the extrusion column 25 moves upward, the rotating wheel 92 rotates through the convex column extrusion, and the rotating wheel 92 drives the second baffle 93 to rotate together, so that the side of the second baffle 93 is turned to the windward side, thereby increasing the area of ​​the second baffle 93 affected by the wind force, so that the first baffle 9 and the second baffle 93 are affected by a greater wind force. When the wind force exerted on the first baffle 9 and the second baffle 93 is greater than the wind force exerted on the wind blocking shell 6 and the elastic force of the first elastic member 51, the first baffle 9 and the second baffle 93 drive the white garbage and the second rotating ring 5 to rotate toward the leeward side, thereby preventing the white garbage from always staying on the upwind side and affecting the monitoring range of the infrared thermal imaging camera 3.

[0050] When the first baffle 9 and the second baffle 93 drive the white garbage and the second rotating ring 5 to rotate, the second rotating ring 5 gradually rotates counterclockwise (from top to bottom), the first elastic member 51 is stretched by force, and the first baffle 9 and the second baffle 93 gradually rotate to the leeward side. In this process, the transmission gear on the first reel 19 rotates along the rotating gear 18, and the second reel 20 rotates together with the first reel 19 through the rope. However, when the first baffle 9 drives the sliding frame 8 to move into the second rotating ring 5, the first baffle 9 is staggered with the through holes on the support plate 7. Therefore, the first baffle 9 is limited in the vertical direction of the support plate 7 and cannot move downward, that is, the third reel 21 cannot reel in the second steel wire rope 212. At this time, the second reel 20 drives the third elastic member 211 to twist and accumulate force during rotation.

[0051] When the second rotating ring 5 rotates counterclockwise (from top to bottom) to an angle close to 90°, the direction of the wind force applied by the white garbage on the first baffle 9 and the second baffle 93 is misaligned with the direction in which the first baffle 9 drives the extrusion column 25 to squeeze the wedge block 24. The first baffle 9 is no longer subjected to the force driving the extrusion column 25 to squeeze the wedge block 24. The extrusion column 25 moves downward and resets under the action of the elastic force of the fifth elastic member 251. The second baffle 93 and the rotating wheel 92 rotate and reset under the drive of the extrusion column 25 according to the same principle as above. At this time, the side surfaces of the first baffle 9 and the second baffle 93 are both wind-receiving surfaces, so that the first baffle 9 and the second baffle 93 are subjected to greater wind force to ensure that the first baffle 9 and the second baffle 93 continue to drive the white garbage to rotate to the leeward side, so that the second rotating ring 5 continues to rotate.

[0052] During the process of the second baffle plate 93 rotating and resetting, the first baffle plate 9 and the sliding frame 8 move and reset synchronously, so that the first baffle plate 9 is aligned with the through hole on the support plate 7 again, so that the first baffle plate 9 is released from the state of being vertically limited by the support plate 7. At this time, the first baffle plate 9 can move downward along the through hole on the support plate 7, and the third elastic member 211 drives the third winding wheel 21 to rotate and rewind the second steel wire rope 212 under the action of its own elastic force. The second steel wire rope 212 pulls the first baffle plate 9, the rotating wheel 92 and the second baffle plate 93 to move downward together, and the fourth elastic member 91 stretches and accumulates force. When the first baffle plate 9 moves downward, the telescopic end of the first pneumatic push rod 22 stops being squeezed, and all elastic airbags 23 contracts and squeezes the gas inside it back into the first pneumatic push rod 22, and the spikes on the elastic airbag 23 are simultaneously retracted into the first baffle 9 and the second baffle 93. At this time, the white garbage is no longer dragged by the spikes. If the white garbage is not entangled with the first baffle 9 and the second baffle 93, the white garbage will break away from the first baffle 9 and the second baffle 93 under the action of wind and float away. At this time, the white garbage is completely away from the infrared thermal imaging camera 3 and will no longer hinder the observation range of the infrared thermal imaging camera 3. In addition, because the floating position of the white garbage is on the leeward side of the first rotating ring 4, the white garbage will no longer cover the infrared thermal imaging camera 3 or the rotating gimbal 2.

[0053] If the spikes on the elastic airbag 23 retract into the first baffle 9 and the second baffle 93, the white garbage is still entangled on the first baffle 9 and the second baffle 93, and the first baffle 9 and the second baffle 93 are still dragged by the white garbage in the direction of the wind, so the first baffle 9 and the second baffle 93 continue to shrink downward, and the sliding frame 8 scrapes the white garbage off during the continued shrinkage of the first baffle 9 and the second baffle 93, preventing the white garbage from moving downward with the first baffle 9 and the second baffle 93. When the top of the second baffle 93 moves downward into the sliding frame 8, the white garbage is detached from the entanglement with the first baffle 9 and the second baffle 93 and floats away with the wind.

[0054] When the white garbage is separated from the first baffle 9 and the second baffle 93, the first baffle 9 and the second baffle 93 are no longer subjected to the pulling force of the white garbage, and the wind blocking shell 6 drives each component to rotate and reset according to the above-mentioned principle of driving the second rotating ring 5 to rotate.

[0055] When the white garbage is very small (i.e., even if the white garbage is hung on the first baffle 9 and the second baffle 93, the second baffle 93 still cannot be rotated), the size of the white garbage will not affect the field of view of the infrared thermal imaging camera 3. When the wind weakens or stops blowing, the turbofan 12 stops rotating, and the limit block 171 drives the adjacent components to reset together. In the process of the first baffle 9 and the second baffle 93 shrinking to the initial state, the small area of ​​white garbage is separated from the first baffle 9 and the second baffle 93 by the same principle as mentioned above. Because the wind has weakened at this time, it is difficult for the white garbage to float upward after it has separated from the first baffle 9 and the second baffle 93, so it will not be hung on the infrared thermal imaging camera 3.

[0056] Example 2: Based on Example 1, Fig.13 and Fig.14 : It also includes a blowing assembly that is simultaneously arranged on the fixed plate 10 and the infrared thermal imaging camera 3. The blowing assembly is used to assist in cleaning dust on the infrared thermal imaging camera 3. The blowing assembly includes a second pneumatic push rod 26 fixedly connected to the right side of the fixed plate 10. The telescopic end of the second pneumatic push rod 26 penetrates the fixed plate 10. The telescopic end of the second pneumatic push rod 26 is inserted into the rotating shaft 11. The telescopic end of the second pneumatic push rod 26 is fixedly connected to a reciprocating screw 27. The reciprocating screw 27 is located in the rotating shaft 11. The reciprocating screw 27 is threaded with the rotating shaft 11 through a ball. The infrared thermal imaging camera 3 is connected with two air jets 28 symmetrically distributed up and down, and the air jets 28 are connected with the second pneumatic push rod 26 through a hose (the hose is not shown). The second pneumatic push rod 26 is provided with a one-way valve connected with the outside world. When the telescopic end of the second pneumatic push rod 26 is extended, the second pneumatic push rod 26 absorbs air from the outside world through the adjacent one-way valve. A one-way valve is provided in the air jet 28. When the telescopic end of the second pneumatic push rod 26 is contracted, the second pneumatic push rod 26 ejects the gas inside from the air jet 28 through the hose.

[0057] After the turbofan 12 rotates to the upwind side, the turbofan 12 drives the reciprocating screw 27 to move back and forth through the ball bearing during the rotation process, so that the telescopic end of the second pneumatic push rod 26 is repeatedly extended and retracted. When the telescopic end of the second pneumatic push rod 26 is extended, the second pneumatic push rod 26 absorbs external air through the one-way valve thereon. When the telescopic end of the second pneumatic push rod 26 is contracted, the second pneumatic push rod 26 conveys the gas inside it to the two jet heads 28 through the hose. The two jet heads 28 spray gas to clean the dust adhering to the lens of the infrared thermal imaging camera 3 to prevent dust from accumulating on the lens of the infrared thermal imaging camera 3. Because the turbofan 12 rotates faster when the wind is strong, the telescopic end of the second pneumatic push rod 26 repeatedly extends and retracts faster at this time, which increases the impact force of the gas sprayed by the two jet heads 28, thereby ensuring sufficient wind power to blow off more stubborn dust.
