Description

Technical Field

[0001] The invention discloses a power transmission line infrared thermal imaging forest fire prevention system, which relates to the technical field of infrared thermal imaging. Background Art

[0002] Transmission towers of transmission lines are sometimes located in mountains and forests. Once a forest fire occurs, the transmission lines will be damaged. Traditional optical monitoring is difficult to implement at night and under thick smoke conditions. For this reason, people use infrared thermal imaging technology to monitor the surrounding environment of the transmission tower and conduct real-time remote monitoring. However, after the existing infrared thermal imaging device is installed on the transmission tower, if there is extreme weather such as heavy rain or strong winds, the infrared thermal imaging device will be washed by rain for a long time, which can easily lead to a decrease in the imaging quality of the infrared thermal imaging device or even damage it, affecting the normal operation of the instrument. Similarly, in windy weather, impurities such as sand and gravel carried by the strong wind will scratch and wear the casing and lens of the infrared thermal imaging device, affecting the normal operation and service life of the thermal imager. Therefore, it is necessary to invent an infrared thermal imaging device with self-protection in extreme weather. Summary of the invention

The second electric push rod 302 is electrically connected to the instrument cleaning module, ensuring that the device can perform targeted cleaning of the infrared thermal imager 101 in different weather conditions, thereby improving the cleaning effect of the device.

[0037] like Figure 5-Figure 8 As shown, the drying component 4 includes two first fixed cylinders 401 with left and right mirror images, the first fixed cylinder 401 is fixedly connected to the rear side of the mounting plate 201, the first fixed cylinder 401 is slidably connected to a sliding curved rod 402, a damper is arranged between the first fixed cylinder 401 and the adjacent sliding curved rod 402, for slowing down the moving speed of the first fixed cylinder 401 relative to the adjacent sliding curved rod 402, a through hole is arranged in the sliding curved rod 402, and five linearly distributed air outlets are arranged on the horizontal part of the sliding curved rod 402, the fixed shell 202 is provided with two first through holes with left and right mirror images and two connecting holes with left and right mirror images, the fixed shell 202 is fixedly connected to a heater 403, and the heater 40 3 is connected and matched with the corresponding connection hole of the fixed shell 202, and the airflow passing through the connection hole of the fixed shell 202 will be heated by the heater 403.

[0038] like Figure 5-Figure 8As shown, the water stain removal component 5 includes a support frame 501, the support frame 501 is fixedly connected to the upper side of the mounting plate 201, the support frame 501 is slidably connected to two first sliding blocks 502 of left and right mirror images, the left side of the support frame 501 is fixedly connected to a first motor 503, the output shaft of the first motor 503 is fixedly connected to a first lead screw 504, the first lead screw 504 is rotatably connected to the support frame 501, the two first sliding blocks 502 are both threadedly connected to the first lead screw 504, the first lead screw 504 is provided with a bidirectional thread, the two first sliding blocks 502 are respectively located at different threads of the first lead screw 504, the first sliding block 502 is slidably connected to an electric roller 505, and a groove is provided at the rear of the electric roller 505. A protrusion is provided at the corner of the sliding curved rod 402, and the groove of the electric roller 505 is limitedly matched with the protrusion of the adjacent sliding curved rod 402. A damping is provided between the groove of the electric roller 505 and the protrusion of the adjacent sliding curved rod 402 to prevent the electric roller 505 and the sliding curved rod 402 from sliding relative to each other. When the electric roller 505 is aligned with the adjacent sliding curved rod 402, the sliding curved rod 402 drives the adjacent electric roller 505 to move up synchronously. The first motor 503 and the electric roller 505 are both electrically connected to the instrument cleaning module. The rainwater on the outer side of the infrared thermal imager 101 is cleaned together by the electric roller 505 and the sliding curved rod 402, thereby enhancing the cleaning effect and working efficiency of the device.

[0039] like Fig. 9 As shown, the waste discharge mechanism 6 includes two sliding shells 601 with left and right mirror images, the two sliding shells 601 are both located in the side wall of the fixed shell 202, the two sliding shells 601 are respectively fixed to the left and right sides of the mounting plate 201, and the mounting plate 201 is provided with a mirror image inclined surface on the side close to the infrared thermal imager 101, which is used to guide the rainwater on the mounting plate 201 into the sliding shell 601, the two sliding shells 601 are both slidably connected to the fixed shell 202, the sliding shell 601 is set to be L-shaped, and an L-shaped chamber for rainwater and gas to pass through is provided in the sliding shell 601, the sliding shell 601 is located in the side wall of the fixed shell 202, the L-shaped chamber of the sliding shell 601 is connected to the second through hole corresponding to the fixed shell 202, and the fixed shell 202 Two second through holes of left and right mirror images are provided on the lower side of the fixed shell 202.

The rotating baffle 603 is sealed and cooperated with the second through hole corresponding to the fixed shell 202. The fixed shell 202 is provided with a groove for limiting the rotation of the rotating baffle 603, which is used to limit the rotation range of the corresponding rotating baffle 603. The fixed shell 202 limits the rotating baffle 603 so that the gas on the outside can only enter the lower side of the fixed shell 202, thereby ensuring the stable compression of the gas between the mounting plate 201 and the fixed shell 202 and the stable operation of the device.

[0040] When the device is used to monitor whether a wildfire occurs around a transmission line, the operator installs the fixed shell 202 of the device at a high place of the transmission tower and wirelessly connects the control panel to the remote control terminal. The operator then sends a signal to the control panel through the remote control terminal, and the instrument cleaning module starts the first electric push rod 203. The telescopic end of the first electric push rod 203 moves upward, and the blind hole at the telescopic end of the first electric push rod 203 drives the sliding ring 207 to move upward synchronously through the limit pin 208. The sliding ring 207 pulls the two first sliding plates 204 to both sides under the support of the corresponding fixed bent rod 205 through two reset ropes 206, and the first sliding plates 204 are connected to the first sliding plates 204. The tension spring connected to the plate 204 is stretched, and as the telescopic end of the first electric push rod 203 moves upward, the telescopic end of the first electric push rod 203 contacts the bottom of the fixed shell 202, and the telescopic end of the first electric push rod 203 pushes the mounting plate 201 to move upward in the fixed shell 202. The tension spring between the mounting plate 201 and the fixed shell 202 is stretched, and as the mounting plate 201 moves upward in the fixed shell 202, the second through holes on both sides of the lower part of the fixed shell 202 suck air into them, and the airflow passing through the second through holes in the lower part of the mounting plate 201 blows the rotating baffle 603 to rotate around the adjacent fixed block 602, and at the same time, the mounting plate 201 drives the parts connected to it to move synchronously.

[0041] When the two first sliding plates 204 move to the limit on both sides, the first sliding plates 204 are blocked by the corresponding fixed bent rods 205 and cannot be pulled by the corresponding reset ropes 206. As the telescopic end of the first electric push rod 203 moves upward, the limit pin 208 disengages from the limit of the blind hole of the telescopic end of the first electric push rod 203, the limit pin 208 compresses the spring connected to it, the sliding ring 207 stops moving and falls to the initial position due to gravity. When the mounting plate 201 moves upward, the mounting plate 201 releases the squeezing of the second sliding plate 210. When the limit block 209 is aligned with the blind hole corresponding to the first sliding plate 204, the first sliding plate 204 is moved upward and inserted into the blind hole corresponding to the first sliding plate 204 under the elastic force of the spring connected to it. The first sliding plate 204 is limited, and the limit block 209 moves upward and drives the second sliding plate 210 to move synchronously through the connecting rope.

[0042] When the mounting plate 201 drives the parts thereon to move upward, the telescopic end of the first electric push rod 203 drives the electric roller 505 through the mounting plate 201 to contact the lower side of the corresponding first sliding plate 204 and then stops. Then the operator enables the monitoring module to start the infrared thermal imager 101 through the remote control terminal. The infrared thermal imager 101 shoots and monitors the environment around the power transmission line. The infrared thermal imager 101 transmits the data captured within the monitoring range back to the remote control terminal.

[0043] When the humidity sensor of the mounting plate 201 detects that the humidity in the air reaches the rated threshold, the speed sensor on the mounting plate 201 feeds back a signal to the remote control terminal, and the remote control terminal makes a judgment based on the relevant data. If it rains, the remote control terminal starts the first electric push rod 203 through the instrument cleaning module, and the telescopic end of the first electric push rod 203 moves downward. Under the tension of the tension spring between the mounting plate 201 and the fixed shell 202, the mounting plate 201 moves downward synchronously with the telescopic end of the first electric push rod 203, and all parts on the mounting plate 201 move downward synchronously. At the same time, the rainwater falling on the mounting plate 201 flows to the left and right sides along its inclined surface, and the rainwater on the mounting plate 201 eventually flows out of the device through the sliding shell 601 and the second through hole of the fixed shell 202.

[0044] As the mounting plate 201 moves downward, the mounting plate 201 squeezes the two second sliding plates 210 to move them downward, and the second sliding plates 210 pull the corresponding limit blocks 209 downward through the connected pull ropes, and the limit blocks 209 compress the springs connected thereto, and the limit blocks 209 release the limit on the adjacent first sliding plates 204, and the two first sliding plates 204 approach each other under the tension of the tension springs connected thereto, and finally the two first sliding plates 204 merge to seal the upper side of the fixed shell 202, so as to prevent external rainwater from entering and damaging the infrared thermal imager 101, thereby extending the service life of the infrared thermal imager 101.

[0045] When the mounting plate 201 squeezes the two second sliding plates 210, the mounting plate 201 squeezes the sliding baffle 301, and the sliding baffle 301 moves downward. The two through holes of the sliding baffle 301 are respectively aligned with the adjacent first through holes and the adjacent connecting holes on the corresponding fixed shell 202. When blocked by the third sliding plate 303, the two through holes of the sliding baffle 301 are not connected with the first through holes and the connecting holes of the corresponding fixed shell 202. Since the two rotating baffles 603 can only rotate inwardly under the limitation of the fixed shell 202, the gas between the mounting plate 201 and the fixed shell 202 cannot be discharged from the device. Therefore, when the mounting plate 201 moves downward, the gas between the mounting plate 201 and the fixed shell 202 is compressed.

[0046] Because it is raining, when the two first sliding plates 204 are merged, the instrument cleaning module starts the two second electric push rods 302 and the two heaters 403, and the telescopic end of the second electric push rod 302 pushes the adjacent third sliding plate 303 to slide on the adjacent sliding baffle 301, and the through hole of the third sliding plate 303 is connected with the through hole on the front side of the adjacent sliding baffle 301, and the compressed gas on the lower side of the mounting plate 201 enters the corresponding connecting hole of the fixed shell 202 through the through hole connecting the sliding baffle 301 and the third sliding plate 303, and the gas flowing in the connecting hole of the fixed shell 202 enters the first fixed cylinder 401 through the corresponding gas transmission hole 404 after being heated by the heater 403, and the high-temperature gas accumulates in the first fixed cylinder 401. Since only the sliding bent rod 402 has a through hole, the gas in the first fixed cylinder 401 is discharged from the air outlet through the through hole of the adjacent sliding bent rod 402, and the sliding bent rod 402 moves upward under the action of the gas pressure in the adjacent first fixed cylinder 401.

[0047] When the two first sliding plates 204 are combined, the instrument cleaning module starts the first motor 503, and the output shaft of the first motor 503 drives the first lead screw 504 to rotate so that the two first sliding blocks 502 are close to each other along the support frame 501. When the electric roller 505 is aligned with the adjacent sliding curved rod 402, the first motor 503 stops. When the sliding curved rod 402 moves upward under the action of the gas pressure in the first fixed cylinder 401, the sliding curved rod 402 drives the electric roller 505 to move upward synchronously, and the electric roller 505 slides upward out of the adjacent first sliding block 502. At the same time, the instrument cleaning module starts the two electric rollers 505. It is made to rotate. Due to the damping between the sliding curved rod 402 and the adjacent electric roller 505, the electric roller 505 cleans the water drops on the infrared thermal imager 101 by rotating upward, and the electric roller 505 and the sliding curved rod 402 do not move relative to each other. Then, the high-temperature gas ejected from the sliding curved rod 402 dries the infrared thermal imager 101. The gas ejected from the sliding curved rod 402 eventually carries water vapor through the two sliding shells 601 and is discharged to the outside from the two second through holes at the bottom of the fixed shell 202, thereby preventing water vapor from entering the infrared thermal imager 101 and causing short-circuit damage to the camera, thereby enhancing the protection effect of the device.

[0048] When encountering strong winds, the wind speed monitoring device transmits a signal to the control panel, and the above operation is repeated. After the second electric push rod 302 is started, its telescopic end pushes the adjacent third sliding plate 303 to move, and the through hole of the third sliding plate 303 is connected with the through hole on the rear side of the adjacent sliding baffle 301, and the compressed gas on the lower side of the mounting plate 201 enters the first through hole corresponding to the fixed shell 202 through the through holes of the sliding baffle 301 and the third sliding plate 303, and the gas entering the first through hole corresponding to the fixed shell 202 is finally ejected from its upper side to impact the infrared thermal imager 101 with airflow, and the infrared thermal imager 101 is formed. The sand and dust on the imager 101 and the upper part of the fixed shell 202 are rolled up by the impact airflow, and the airflow carrying the sand and dust is finally discharged to the outside of the device through the two second through holes at the lower part of the two sliding shells 601 and the fixed shell 202. When the humidity sensor or the wind speed monitoring device detects that the external weather conditions are stable, the reverse operation is performed, and the infrared thermal imager 101 is extended again for monitoring, and all parts are reset, thereby protecting the safety and working stability of the infrared thermal imager 101, avoiding damage and destruction to the infrared thermal imager 101 by extreme weather, and extending the service life of the device.

[0049] Embodiment 2: Based on embodiment 1, Fig. 9 and Fig.10 As shown, it also includes a debris removal mechanism 7, which is arranged on the fixed shell 202. The debris removal mechanism 7 is used to clean up the debris attached to the infrared thermal imager 101. The debris removal mechanism 7 includes a second fixed cylinder 701 with a mirror image. The second fixed cylinder 701 is fixedly connected to the bottom surface of the fixed shell 202. A sliding column 702 is slidably connected in the second fixed cylinder 701. The sliding column 702 is fixedly connected to the mounting plate 201. The second fixed cylinder 701 is connected to a gas pipe 703. A one-way valve is arranged on the lower side of the second fixed cylinder 701 to replenish the missing gas in the second fixed cylinder 701. The mounting plate 201 is rotatably connected to two groups of rotating nozzles 704 with left and right mirror images. Each group of rotating nozzles 704 consists of two front and rear mirror images. A cylindrical block is arranged on the side of the rotating nozzle 704 close to the inner wall of the fixed shell 202 The fixed shell 202 is provided with two groups of serpentine grooves of front and rear mirror images, and each group of serpentine grooves is composed of two left and right mirror images. The serpentine groove of the fixed shell 202 is limited by the cylindrical block of the adjacent rotating nozzle 704. During the rising process of the rotating nozzle 704 along with the mounting plate 201, the cylindrical block of the rotating nozzle 704 slides in the adjacent serpentine groove on the fixed shell 202. Due to the limitation of the cylindrical block of the rotating nozzle 704 by the serpentine groove of the fixed shell 202, the rotating nozzle 704 continuously swings during the rising process of the mounting plate 201, and the rotating nozzle 704 is connected with the adjacent air supply pipe 703. The serpentine groove of the fixed shell 202 is limited by the cylindrical block of the rotating nozzle 704 to achieve the effect of swinging and blowing, thereby achieving the purpose of removing debris attached to the infrared thermal imager 101 and enhancing the cleaning effect of the device.

[0050] Due to strong winds, some debris may be rolled up. If these debris fall on the infrared thermal imager 101, it will not only affect its monitoring effect, but also make it difficult to clean the infrared thermal imager 101. Therefore, in the process of driving the infrared thermal imager 101 to move down for protection, it is necessary to clean the debris on it. The specific operation is as follows: when the mounting plate 201 moves up to drive the infrared thermal imager 101 to extend out of the fixed shell 202, the mounting plate 201 drives the sliding column 702 to move up in the adjacent second fixed cylinder 701, and the gas between the mounting plate 201 and the fixed shell 202 enters the second fixed cylinder 701 through the one-way valve at the bottom of the second fixed cylinder 701. When the mounting plate 201 moves up to drive the infrared thermal imager 101 to extend out of the fixed shell 202, the sliding column 702 moves up in the adjacent second fixed cylinder 701. 01 moves downward, the mounting plate 201 presses the gas in the adjacent second fixed cylinder 701 into the corresponding gas pipe 703 through the sliding column 702, and finally sprays it upward through the two adjacent rotating nozzles 704. At the same time, when the mounting plate 201 moves downward, the four rotating nozzles 704 move downward synchronously, and the cylindrical blocks on the rotating nozzles 704 slide in the serpentine grooves on the inner walls of the corresponding fixed shells 202, so that the rotating nozzles 704 swing continuously during the descent process. The rotating nozzles 704 swing continuously during the process of jetting away the debris on the infrared thermal imager 101, thereby preventing the blown-away debris from falling back into the fixed shell 202, thereby ensuring the cleaning effect of the device.

[0051] Embodiment 3: Based on embodiment 2, Figure 1 and Figure 11-13As shown, it also includes a lens cleaning mechanism 8, which is arranged on the infrared thermal imager 101. The lens cleaning mechanism 8 is used to regularly clean the dust and gravel on the lens surface of the infrared thermal imager 101. The lens cleaning mechanism 8 includes a second motor 801, the control panel is electrically connected to the lens cleaning module, the second motor 801 is electrically connected to the lens cleaning module, the second motor 801 is fixedly connected to the lower side of the infrared thermal imager 101, the output shaft of the second motor 801 is fixedly connected to the second lead screw 802, the second lead screw 802 is rotatably connected to the infrared thermal imager 101, the second lead screw 802 is threadedly connected to the second sliding block 803, and the second lead screw 802 is threadedly connected to the second sliding block 803. The second sliding block 803 is limited in position with the infrared thermal imager 101. The second sliding block 803 is limited by the infrared thermal imager 101, and the second lead screw 802 rotates to drive the second sliding block 803 to move. A gas cylinder 804 is fixedly connected to the right side of the infrared thermal imager 101. A piston rod 805 is sealed and slidably connected in the gas cylinder 804. A tension spring is fixedly connected between the piston rod 805 and the second sliding block 803. A rotating block 806 is rotatably connected to the upper side of the second sliding block 803. A cylindrical wheel is provided on the lower side of the rotating block 806. The cylindrical wheel of the rotating block 806 is pressed and matched with the infrared thermal imager 101. When the second sliding block 803 moves, Due to the friction force at the contact point between the cylindrical wheel of the rotating block 806 and the infrared thermal imager 101, the rotating block 806 rotates on the second sliding block 803. The upper part of the rotating block 806 is provided with two centrally symmetrical inclined surfaces. The two inclined surfaces on the upper part of the rotating block 806 are arc-shaped in the horizontal direction. The second sliding block 803 is fixedly connected with a gas guide rod 807. The gas guide rod 807 penetrates the rotating block 806 and is rotatably connected thereto. The gas guide rod 807 is provided with through holes distributed in a linear array. The gas guide rod 807 is slidably connected with a sliding rod 808. The sliding rod 808 is extruded and matched with the inclined surface of the rotating block 806. As the rotating block 806 rotates, the inclined surface of the rotating block 806 is squeezed. The sliding rod 808 is pressed to make it move up and down continuously. The through hole of the air guide rod 807 is connected to a hose, which is used to cooperate with the sliding rod 808 to achieve the purpose of swinging and blowing. The sliding rod 808 moves up and down to squeeze the hose of the air guide rod 807, so that the direction of the hose mouth of the air guide rod 807 is continuously changed up and down. The second sliding block 803 is rotatably connected to the cleaning cylinder 809. The air guide rod 807 is connected to the air delivery cylinder 804 through the air guide tube. The purpose of swinging and blowing is achieved through the air guide rod 807 and the sliding rod 808, thereby cleaning the gravel on the surface of the lens of the infrared thermal imager 101, avoiding scratches on the lens during later wiping, and ensuring the effectiveness and stability of cleaning.

[0052] In windy weather, when the wind speed is not high, the infrared thermal imager 101 continues to work. However, after the infrared thermal imager 101 has worked for a period of time or in daily use, a layer of dust and sand particles will accumulate on the lens surface, which needs to be cleaned. The specific operation is as follows: when the image quality detected by the infrared thermal imager 101 decreases, the remote control terminal starts the second motor 801 through the lens cleaning module, and the output shaft of the second motor 801 drives the second lead screw 802 to rotate, and the second lead screw 802 drives the second sliding The block 803 moves to the right, and the second sliding block 803 pulls the piston rod 805 to slide into the gas cylinder 804 through the tension spring. The gas in the gas cylinder 804 enters the through hole of the gas guide rod 807 through the gas guide pipe and is finally ejected from its hose. As the second sliding block 803 drives the rotating block 806 to move to the right, the cylindrical wheel at the bottom of the rotating block 806 is frictionally driven by the infrared thermal imager 101, and the rotating block 806 rotates. The inclined surface at the top of the rotating block 806 pushes the sliding rod 808 to move upward. The continuous inclined plane, as the rotating block 806 moves to the right, the sliding rod 808 moves up and down continuously, and the sliding rod 808 pushes the hose of the air guide rod 807 to swing up and down, and the swing of the hose of the air guide rod 807 cleans the surface of the lens of the infrared thermal imager 101 to remove gravel and dust, and the cleaning cylinder 809 wipes the lens of the infrared thermal imager 101 after blowing and cleaning. When the lens of the infrared thermal imager 101 is cleaned once, the lens cleaning module reverses the second motor 801 to make the second sliding block 80 3 moves to the left to reset. Due to the limitation of the hose and the sliding rod 808, the rotating block 806 does not rotate during the left movement. At the same time, the gas cylinder 804 replenishes gas through the gas pipe and the gas rod 807. After the second sliding block 803 returns to its original position, the second motor 801 repeats the above operation. When the lens is cleaned, the second motor 801 stops, and the piston rod 805 re-accumulates gas through the one-way valve of the gas cylinder 804, thereby ensuring the detection accuracy of the infrared thermal imager 101 and improving the accuracy of the work.
