Description

Technical Field

[0001] The invention belongs to the technical field of special vehicles, and in particular to a monitoring and early warning device and an early warning system for preventing special vehicles from touching high-voltage lines. Background Art

[0002] Special vehicles refer to various wheeled or tracked special vehicles used for towing, obstacle removal, cleaning, lifting, loading and unloading, lifting, mixing, excavation, bulldozing, road rolling, etc., or vehicles equipped with fixed special instruments and equipment inside, engaged in professional work such as monitoring, fire fighting, cleaning, medical treatment, TV broadcasting, radar, X-ray inspection, etc., such as aerial platforms, cranes, dump trucks, sweepers, cementing trucks, fracturing trucks, highway tow trucks, etc.

[0003] There are also some technical solutions for special vehicles in the prior art, such as a Chinese patent with application number 2017114568945, which discloses a hybrid arm type aerial work vehicle with multiple degrees of freedom movement, including a vehicle body, a horizontal rotation unit installed on the vehicle body, and a hybrid arm installed on the horizontal rotation unit; the end of the hybrid arm is connected to the working platform; it also includes: a crank arm, a crank arm rotation mounting seat, a swing unit and a crank arm variable amplitude telescopic mechanism, wherein one end of the crank arm is connected to the hybrid arm through the crank arm rotation mounting seat, and the swing unit provides horizontal rotation power for the crank arm rotation mounting seat; the crank arm is variable in amplitude within the amplitude plane through the crank arm variable amplitude telescopic mechanism; and the working platform rotation device and the working platform lifting device are arranged between the other end of the crank arm and the working platform. The working vehicle has multiple functions such as the vertical lifting action of the linked folding arm, the variable amplitude of the crank arm and the rotation of the crank arm, and the lifting and rotation of the working platform, which solves the current problems of the single function and limited working range of aerial work vehicles.

[0004] In the above technology, the telescopic arm is likely to touch the high-voltage line during movement, causing accidents and seriously threatening the lives of operators. Previous monitoring equipment and sensors only have the function of feedback on high-voltage lines and cannot stop the vehicle operating equipment from working.

[0005] To this end, the present invention provides a monitoring and early warning device and an early warning system for preventing special vehicles from touching high-voltage lines. Summary of the invention

[0006] In order to make up for the shortcomings of the existing technology and solve the problem that the telescopic arm is easy to touch the high-voltage line during movement, causing accidents and seriously threatening the life safety of the operators, the previous monitoring equipment and sensors only have the function of feedback of the high-voltage line and cannot stop the vehicle operating equipment from working. The present invention proposes a special vehicle anti-touching high-voltage line monitoring and early warning device and early warning system.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a special vehicle anti-touching high-voltage line monitoring and early warning device described in the present invention comprises a camera, a sleeve arm and a telescopic arm, and the telescopic arm is slidably connected in the sleeve arm; the sleeve arm is fixedly connected with a mounting shell at a position close to the telescopic arm; a voltage proximity sensor is installed on the outside of the mounting shell; an electric cylinder is arranged on the inside of the mounting shell, and the output rod of the electric cylinder faces the telescopic arm; a plurality of grooves are evenly arranged on the side of the telescopic arm close to the electric cylinder; the early warning device can be installed on special vehicles with telescopic arms such as aerial platforms and cranes. The model of the voltage proximity sensor is KDS-01, which can be detected in a non-contact situation. During the movement or operation of the special vehicle, the camera takes real-time pictures of the operation scene on site. If the voltage proximity sensor detects that there is a high-voltage line nearby, the electric cylinder starts to work and inserts the output rod into the groove, so that the telescopic arm is locked and can no longer slide in the sleeve arm, thereby prohibiting the telescopic arm from moving again, avoiding accidents caused by touching the high-voltage line, and ensuring the safety of the operators.

[0008] Preferably, a No. 1 slide groove is opened on the inner side of the mounting shell near the electric cylinder; a slider is slidably connected in the No. 1 slide groove, and the electric cylinder is fixedly connected to the slider; a No. 1 magnet is fixedly connected to the output rod; a No. 2 magnet is fixedly connected to the bottom of the groove; because the special vehicle needs to frequently slide the telescopic arm in the socket arm during operation, the position of the telescopic arm in the socket wall is uncertain, and the output rod and the groove may not be aligned. At this time, through the attraction between the No. 1 magnet and the No. 2 magnet, when the telescopic arm moves, it will drive the electric cylinder to move slightly, thereby aligning the output rod with the groove, so that the subsequent output rod can be smoothly inserted into the groove, ensuring that the early warning device can operate normally.

[0009] Preferably, a cavity is provided in the mounting shell near the No. 1 slide groove; a plurality of sliding holes are evenly provided between the cavity and the No. 1 slide groove; a locking rod is slidably connected in the sliding hole; a tension spring is fixedly connected between the locking rod and the inner wall of the cavity; an airbag is fixedly connected to the free end of the output rod; the airbag and the cavity are connected by a hose; after the output rod is inserted into the groove, since the slider can be displaced slightly in the No. 1 slide groove, the telescopic rod can still move slightly, which involves certain risks. At this time, the airbag is squeezed by the groove, and the gas in the airbag enters the cavity through the hose and pushes multiple locking rods into the No. 1 slide groove, so that the locking rod clamps the slider, restricts the movement of the slider and the electric cylinder, thereby avoiding the problem that the telescopic rod can still move slightly.

[0010] Preferably, the mounting shell is rotatably connected to a turntable near the end of the telescopic arm, and the turntable is fitted with the surface of the telescopic arm; a stopper is fixedly connected to the position of the mounting shell near the turntable through a bracket; a plurality of elastic bags are evenly distributed on the outer circumference of the turntable; an ash inlet and an ash outlet are provided on the elastic bag, and a one-way valve is provided in the ash inlet and the ash outlet; since the groove is exposed to the air at the construction site, dust can easily enter the groove, and over time, excessive accumulation of dust will affect the engagement between the output rod and the groove, and in the process of the telescopic arm sliding into the sleeve arm, the turntable will be driven to rotate, and the elastic bag will be squeezed and contracted by the stopper, and then the elastic bag will break away from the stopper and enter the groove, at this time, the elastic bag recovers and sucks the dust in the groove into the elastic bag through the ash inlet, and when the elastic bag is rotated to the position of the stopper again, it will be squeezed and contracted again, and then the air inside it together with the dust will be sprayed out through the ash outlet, thereby cleaning the groove and ensuring that the output rod can be normally inserted into the groove.

[0011] Preferably, a plurality of tooth blocks are evenly distributed on the outer circumference of the turntable; a plurality of tooth grooves are evenly opened on the side of the telescopic arm close to the turntable, and the tooth blocks mesh with the tooth grooves; by providing the tooth blocks and tooth grooves, the coupling efficiency between the turntable and the telescopic arm is improved, ensuring that the telescopic arm can smoothly drive the turntable to rotate, avoiding the problem that the elastic bag cannot smoothly enter the groove due to slipping between the telescopic arm and the turntable, thereby allowing the work of cleaning the groove to proceed smoothly.

[0012] Preferably, a rubber pad is provided inside the installation shell; a plurality of elastic strips are fixedly connected to the position of the rubber pad in the installation shell through a support plate; an inclined baffle No. 1 is provided on the support plate below the elastic strip; some gravel will inevitably fall into the groove, and when the elastic bag inhales dust, it will adsorb the gravel to the outside of the ash inlet and drive the gravel to rotate together. When the elastic bag rotates to the position of the elastic strip, friction is generated with the elastic strip, and then the elastic strip peels off the gravel adsorbed on the elastic bag, and rolls along the baffle No. 1 to the position of the rubber pad, and finally adheres to the rubber pad to complete the collection of the gravel. This operation can avoid the problem that after the gravel rotates to the position of the block with the elastic bag, the gravel is peeled off by the block and falls back into the groove or hits pedestrians.

[0013] Preferably, baffle No. 1 is hinged to the support plate through a torsion spring; baffle No. 2 is hinged on the inner wall of the mounting shell above the elastic strip through a torsion spring; the mounting shell is rotatably connected to a guide wheel through a bracket near baffle No. 2; a connecting rope is fixed to baffle No. 1, and the other end of the connecting rope passes around the guide wheel and is fixed to baffle No. 2; after the elastic bag is separated from the elastic strip, it continues to rotate and move baffle No. 2, and baffle No. 2 rotates and pulls baffle No. 1 through the connecting rope, so that baffle No. 1 rotates in the direction of the rubber pad, and the gravel on its upper side is bounced onto the rubber pad, so that the rubber pad absorbs the gravel more firmly, avoiding the problem that the gravel cannot roll smoothly onto the rubber pad after falling on baffle No. 1.

[0014] Preferably, an external plate is slidably connected to the installation shell through the No. 2 slide groove, and the external plate extends to the outside of the installation shell; the rubber pad is adhered to the side of the external plate close to the turntable; by setting the external plate, after the early warning device has been used for a period of time, if there is too much gravel accumulation on the rubber pad, the staff can regularly pull out the external plate together with the rubber pad, and then replace the rubber pad, so that the slag removal work can be carried out continuously, ensuring the normal use of the early warning device.

[0015] Preferably, a small hole is provided on the elastic strip; the connecting rope passes through the small hole and is slidably connected to the elastic strip; a plurality of spring sheets are evenly fixed on the connecting rope; during the frictional contact between the elastic strip and the elastic bag, dust on the outside of the elastic bag will remain on the elastic strip, and by providing the small hole and a plurality of spring sheets, the connecting rope can slide back and forth in the small hole during the up and down movement of the connecting rope, and at the same time, the spring sheet will drive the elastic strip to shake when passing through the small hole, thereby shaking off the dust adhered to the elastic strip, and finally bounce the dust onto the rubber pad through the No. 1 baffle, thereby increasing the self-cleaning effect of the elastic strip and ensuring the normal progress of the slag removal work.

[0016] A special vehicle anti-touch high-voltage line monitoring and early warning system, the system is applicable to the above-mentioned special vehicle anti-touch high-voltage line monitoring and early warning device, including a monitoring module, a data processing module and a locking module;

[0018] The data processing module includes a processor, a memory and a cloud service platform; the camera saves the captured images to the local memory and uploads them to the cloud service platform. When there is a problem with the local memory, it is convenient to retrieve the data directly from the cloud service platform later;

[0019] The locking module includes an electric cylinder, an output rod and a groove; if the voltage proximity sensor detects the presence of a high-voltage line nearby, it will transmit a signal to the processor. The processor analyzes the shooting scene and calculates the distance to the high-voltage line. If the distance is less than a certain threshold, the processor controls the electric cylinder to insert the output rod into the groove, so that the telescopic arm is locked and cannot move anymore.

[0020] The beneficial effects of the present invention are as follows:

The early warning device can be installed on special vehicles with telescopic arms such as aerial platforms and cranes. When the special vehicle is moving or working, the camera takes real-time photos of the on-site operation screen.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figures 1 to 6 As shown, a monitoring and early warning device for preventing a special vehicle from touching a high-voltage line according to the present invention comprises a camera 1, a sleeve arm 2 and a telescopic arm 3, and the telescopic arm 3 is slidably connected in the sleeve arm 2; a mounting shell 4 is fixedly connected to the sleeve arm 2 near the telescopic arm 3; a voltage proximity sensor 5 is mounted on the outside of the mounting shell 4; an electric cylinder 6 is arranged on the inside of the mounting shell 4, and an output rod 7 of the electric cylinder 6 faces the telescopic arm 3; a plurality of grooves 8 are evenly arranged on one side of the telescopic arm 3 near the electric cylinder 6; the early warning device can be installed on a special vehicle with a telescopic arm 3 such as a climbing vehicle and a crane, the model of the voltage proximity sensor 5 is KDS-01, and detection can be performed in a non-contact manner. During the movement or operation of the special vehicle, the camera 1 takes real-time pictures of the operation scene on site. If the voltage proximity sensor 5 detects that there is a high-voltage line nearby, the electric cylinder 6 starts to work and inserts the output rod 7 into the groove 8, so that the telescopic arm 3 is locked and can no longer slide in the sleeve arm 2, thereby prohibiting the telescopic arm 3 from moving again, avoiding accidents caused by touching the high-voltage line, and ensuring the safety of the operator.

[0036] A No. 1 slide groove 9 is provided on the inner side of the mounting shell 4 near the electric cylinder 6; a slider 10 is slidably connected in the No. 1 slide groove 9, and the electric cylinder 6 is fixedly connected to the slider 10; a No. 1 magnet 11 is fixedly connected to the output rod 7; a No. 2 magnet 12 is fixedly connected to the bottom of the groove 8; since the special vehicle often needs to let the telescopic arm 3 slide in the socket arm 2 during operation, the position of the telescopic arm 3 in the socket wall is uncertain, and the output rod 7 and the groove 8 may not be aligned. At this time, through the attraction between the No. 1 magnet 11 and the No. 2 magnet 12, when the telescopic arm 3 moves, it will drive the electric cylinder 6 to move slightly, so that the output rod 7 is aligned with the groove 8, so that the subsequent output rod 7 can be smoothly inserted into the groove 8, ensuring the normal operation of the early warning device.

[0037] A cavity 13 is provided in the mounting shell 4 near the No. 1 slide groove 9; a plurality of sliding holes 14 are evenly provided between the cavity 13 and the No. 1 slide groove 9; a locking rod 15 is slidably connected in the sliding hole 14; a tension spring 16 is fixedly connected between the locking rod 15 and the inner wall of the cavity 13; an air bag 17 is fixedly connected to the free end of the output rod 7; the air bag 17 and the cavity 13 are connected through a hose 18; after the output rod 7 is inserted into the groove 8, since the slider 10 can be displaced slightly in the No. 1 slide groove 9, the telescopic rod can still move slightly, which involves certain risks. At this time, the air bag 17 is squeezed by the groove 8, and the gas in the air bag 17 enters the cavity 13 through the hose 18, and pushes multiple locking rods 15 to extend into the No. 1 slide groove 9, and then the locking rod 15 clamps the slider 10, restricts the movement of the slider 10 and the electric cylinder 6, thereby avoiding the problem that the telescopic rod can still move slightly.

[0038] The end of the mounting shell 4 near the telescopic arm 3 is rotatably connected with a turntable 19, and the turntable 19 is in contact with the surface of the telescopic arm 3; the mounting shell 4 is fixed with a stopper 20 near the turntable 19 through a bracket; a plurality of elastic capsules 21 are evenly distributed on the outer circumference of the turntable 19; an ash inlet 22 and an ash outlet 23 are provided on the elastic capsule 21, and a one-way valve is provided in the ash inlet 22 and the ash outlet 23; since the groove 8 is exposed to the air at the construction site, dust can easily enter the groove 8, and over time, excessive dust accumulation will affect the gap between the output rod 7 and the groove 8 When the telescopic arm 3 slides into the sleeve arm 2, the turntable 19 is driven to rotate, and the elastic bag 21 is squeezed by the block 20 and then contracts, and then the elastic bag 21 breaks away from the block 20 and enters the groove 8. At this time, the elastic bag 21 recovers and sucks the dust in the groove 8 into the elastic bag 21 through the ash inlet 22. When the elastic bag 21 is rotated to the position of the block 20 again, it is squeezed and contracts again, and then the air inside it together with the dust is ejected outward through the ash outlet 23, thereby cleaning the groove 8 and ensuring that the output rod 7 can be normally inserted into the groove 8.

[0039] A plurality of tooth blocks 24 are evenly distributed on the outer circumference of the turntable 19; a plurality of tooth grooves 25 are evenly opened on the side of the telescopic arm 3 close to the turntable 19, and the tooth blocks 24 mesh with the tooth grooves 25; by providing the tooth blocks 24 and the tooth grooves 25, the coupling efficiency between the turntable 19 and the telescopic arm 3 is improved, ensuring that the telescopic arm 3 can smoothly drive the turntable 19 to rotate, avoiding the problem that the elastic bag 21 cannot smoothly enter the groove 8 due to slipping between the telescopic arm 3 and the turntable 19, thereby allowing the work of cleaning the groove 8 to proceed smoothly.

[0040] A rubber pad 26 is provided inside the installation shell 4; a plurality of elastic strips 28 are fixedly connected to the position near the rubber pad 26 in the installation shell 4 through a support plate 27; an inclined No. 1 baffle plate 29 is provided on the support plate 27 below the elastic strip 28; some gravel will inevitably fall into the groove 8, and the elastic bag 21 will absorb the dust while adsorbing the gravel on the outside of the ash inlet 22, and drive the gravel to rotate together, and when the elastic bag 21 rotates to the position of the elastic strip 28, friction is generated with the elastic strip 28, and then the elastic strip 28 peels off the gravel adsorbed on the elastic bag 21, and rolls to the position of the rubber pad 26 along the No. 1 baffle plate 29, and finally adheres to the rubber pad 26, completing the collection of the gravel, and this operation can avoid the problem that after the gravel rotates to the position of the block 20 with the elastic bag 21, the gravel is peeled off by the block 20, falls into the groove 8 again or hits pedestrians.

[0041] The No. 1 baffle 29 is hinged to the support plate 27 through a torsion spring; the No. 2 baffle 30 is hinged on the inner wall of the mounting shell 4 above the elastic strip 28 through a torsion spring; the mounting shell 4 is rotatably connected to a guide wheel 31 at a position close to the No. 2 baffle 30 through a bracket; the No. 1 baffle 29 is fixedly connected to the No. 1 baffle 29, and the other end of the connecting rope 34 passes around the guide wheel 31 and is fixedly connected to the No. 2 baffle 30; after the elastic bag 21 is separated from the elastic strip 28, it continues to rotate and moves the No. 2 baffle 30, and the No. 2 baffle 30 rotates and pulls the No. 1 baffle 29 through the connecting rope 34, so that the No. 1 baffle 29 rotates toward the rubber pad 26, and the gravel on its upper side is bounced onto the rubber pad 26, so that the rubber pad 26 absorbs the gravel more firmly, avoiding the problem that the gravel cannot roll smoothly onto the rubber pad 26 after falling on the No. 1 baffle 29.

[0042] The installation shell 4 is slidably connected with an external plate 32 through a No. 2 slide groove, and the external plate 32 extends to the outside of the installation shell 4; the rubber pad 26 is adhered to the side of the external plate 32 close to the turntable 19; by setting the external plate 32, after the early warning device has been used for a period of time, if there is too much gravel accumulation on the rubber pad 26, the staff can regularly pull out the external plate 32 together with the rubber pad 26, and then replace the rubber pad 26, so that the slag removal work can be carried out continuously, ensuring the normal use of the early warning device.

[0043] Embodiment 2

[0044] like Figure 7As shown, compared with Example 1, as another implementation of the present invention, a small hole is opened on the elastic strip 28; the connecting rope 34 passes through the small hole and is slidably connected to the elastic strip 28; a plurality of spring pieces 33 are evenly fixed on the connecting rope 34; during the friction contact between the elastic strip 28 and the elastic bag 21, the dust on the outside of the elastic bag 21 will remain on the elastic strip 28. By providing a small hole and a plurality of spring pieces 33, the connecting rope 34 can slide back and forth in the small hole during the up and down movement of the connecting rope 34. At the same time, the spring piece 33 will drive the elastic strip 28 to shake when passing through the small hole, thereby shaking off the dust adhered to the elastic strip 28, and finally bounce the dust onto the rubber pad 26 through the No. 1 baffle 29, thereby increasing the self-cleaning effect of the elastic strip 28 and ensuring the normal progress of the slag removal work.

[0045] like Figure 8 As shown, a special vehicle anti-touching high-voltage line monitoring and early warning system described in the present invention is applicable to the above-mentioned special vehicle anti-touching high-voltage line monitoring and early warning device, including a monitoring module, a data processing module and a locking module;

[0046] The monitoring module includes a camera 1 and a voltage proximity sensor 5; the camera 1 is used to capture the monitoring scene in real time, and the voltage proximity sensor 5 detects whether there is a high-voltage line nearby;

[0047] The data processing module includes a processor, a memory and a cloud service platform; the camera 1 saves the captured images to the local memory and uploads them to the cloud service platform. When there is a problem with the local memory, it is convenient to retrieve the data directly from the cloud service platform later;

[0048] The locking module includes an electric cylinder 6, an output rod 7 and a groove 8; if the voltage proximity sensor 5 detects the presence of a high-voltage line nearby, it will transmit a signal to the processor, and the processor will analyze the shooting scene and calculate the distance to the high-voltage line. If the distance is less than a certain threshold, the processor will control the electric cylinder 6 to work and insert the output rod 7 into the groove 8, so that the telescopic arm 3 is locked and cannot move anymore.

[0049] Working principle: This early warning device can be installed on special vehicles with telescopic arms 3, such as aerial platforms and cranes. The voltage proximity sensor 5 is of model KDS-01, which can detect without contact. When the special vehicle is moving or working, the camera 1 takes real-time pictures of the working scene. If the voltage proximity sensor 5 detects the presence of a high-voltage line nearby, the electric cylinder 6 starts to work and inserts the output rod 7 into the groove 8, so that the telescopic arm 3 is locked and can no longer slide in the sleeve arm 2, thereby prohibiting the telescopic arm 3 from moving again, avoiding accidents caused by touching the high-voltage line, and ensuring the safety of the operators. Since special vehicles need to be in the process of work, The telescopic arm 3 needs to be frequently slid in the sleeve arm 2, so the position of the telescopic arm 3 in the sleeve wall is uncertain, and the output rod 7 may not be aligned with the groove 8. At this time, through the attraction between the No. 1 magnet 11 and the No. 2 magnet 12, when the telescopic arm 3 moves, it will drive the electric cylinder 6 to move slightly, so that the output rod 7 is aligned with the groove 8, so that the subsequent output rod 7 can be smoothly inserted into the groove 8, ensuring that the early warning device can operate normally; after the output rod 7 is inserted into the groove 8, since the slider 10 can be slightly displaced in the No. 1 slide groove 9, the telescopic rod can still move slightly, which poses a certain risk. At this time, the airbag 17 is squeezed by the groove 8, and the airbag 17 The gas in the cavity 13 enters the cavity 13 through the hose 18, and pushes the multiple locking rods 15 to extend into the No. 1 slide groove 9, and then the locking rods 15 clamp the slider 10, limiting the movement of the slider 10 and the electric cylinder 6, thereby avoiding the problem that the telescopic rod can still move slightly; because the groove 8 is exposed to the air at the construction site, dust easily enters the groove 8, and over time, excessive dust accumulation will affect the engagement between the output rod 7 and the groove 8. In the process of the telescopic arm 3 sliding into the sleeve arm 2, it will drive the turntable 19 to rotate, and the elastic capsule 21 will be squeezed by the block 20 and then contracted, and then the elastic capsule 21 will break away from the block 20 and enter the groove 8, and the elastic capsule 21 will recover at this time. The dust in the groove 8 is sucked into the elastic capsule 21 through the ash inlet 22. When the elastic capsule 21 is rotated to the position of the stopper 20 again, it is squeezed and contracted again, and then the air inside it together with the dust is ejected outward through the ash outlet 23, thereby cleaning the groove 8 and ensuring that the output rod 7 can be normally inserted into the groove 8. The tooth block 24 and the tooth groove 25 are provided to improve the coupling efficiency between the turntable 19 and the telescopic arm 3, ensuring that the telescopic arm 3 can smoothly drive the turntable 19 to rotate, avoiding the problem that the elastic capsule 21 cannot smoothly enter the groove 8 due to slipping between the telescopic arm 3 and the turntable 19, thereby making it possible to smoothly clean the groove 8.Some gravel will inevitably fall into the groove 8. When the elastic bag 21 absorbs dust, it will adsorb the gravel to the outside of the ash inlet 22 and drive the gravel to rotate together. When the elastic bag 21 rotates to the position of the elastic strip 28, it rubs with the elastic strip 28, and then the elastic strip 28 peels off the gravel adsorbed on the elastic bag 21, and rolls along the first baffle 29 to the position of the rubber pad 26, and finally adheres to the rubber pad 26 to complete the collection of gravel. This operation can avoid crushing After the slag rotates to the position of the stopper 20 with the elastic bag 21, the crushed slag is peeled off by the stopper 20 and falls back into the groove 8 or hits pedestrians; after the elastic bag 21 is separated from the elastic strip 28, it continues to rotate and moves the second baffle 30, and the second baffle 30 rotates and pulls the first baffle 29 through the connecting rope 34, so that the first baffle 29 rotates toward the rubber pad 26 and bounces the crushed slag on its upper side onto the rubber pad 26, so that the rubber pad 26 absorbs the crushed slag more firmly. The problem that the gravel slag cannot be smoothly rolled onto the rubber pad 26 after falling onto the first baffle plate 29 is avoided; by setting the external plate 32, after the early warning device has been used for a period of time, if there is too much gravel slag on the rubber pad 26, the staff can regularly pull out the external plate 32 together with the rubber pad 26, and then replace the rubber pad 26, so that the slag removal work can be carried out continuously, ensuring the normal use of the early warning device; during the friction contact between the elastic strip 28 and the elastic capsule 21, the dust on the outside of the elastic capsule 21 will remain on the elastic strip 28, and by setting the small hole and a plurality of spring pieces 33, the connecting rope 34 can slide back and forth in the small hole during the up and down movement of the connecting rope 34, and at the same time, the spring piece 33 will drive the elastic strip 28 to shake when passing through the small hole, so as to shake off the dust adhering to the elastic strip 28, and finally bounce the dust onto the rubber pad 26 through the first baffle plate 29, thereby increasing the self-cleaning effect of the elastic strip 28 and ensuring the normal progress of the slag removal work. ;
