Coal is often transported continuously by conveyor belts. Compared with other operating systems in thermal power plants, the operating environment of the fuel transportation system is relatively harsh, the operating line is long, and the equipment structure is relatively simple.

Although this processing method can monitor and process abnormal areas of the belt in a timely manner, it cannot effectively identify the abnormal data parts, and cannot confirm on-site whether it is a problem with the belt itself or a problem of interference from the external environment. The method of using alarms and notifying manual on-site processing undoubtedly increases the time for handling crises, increases the damage time and degree of continuous operation of the conveyor belt, and is prone to safety accidents caused by the breakage of the coal conveyor belt, reducing the emergency response capabilities and intelligent level of safe production of the power plant.

[0035] 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.

[0036] The embodiment of the present invention provides an intelligent monitoring device for a coal conveyor belt, thereby solving the problem that it is difficult to monitor the damage of the conveyor belt in real time and issue an early warning, thereby reducing the emergency response capability and intelligent level of safe production of the power plant.

[0037] like Figures 1 to 13As shown, a preferred embodiment of the present invention proposes an intelligent monitoring device for a coal conveyor belt, comprising a track frame 1, a conveyor belt 2, a conveyor roller 3 and a detection component, wherein the conveyor belt 2 and the conveyor roller 3 are both mounted on the track frame 1, and the conveyor roller 3 is in rolling contact with the conveyor belt 2, the detection component is mounted in the track frame 1, and the detection component includes two visual monitoring components with the same structure and function, wherein the area close to the unloading point of the conveyor belt 2 is set as a first visual monitoring component 4, and the area away from the unloading point of the conveyor belt 2 is set as a second visual monitoring component 5, the first visual monitoring component 4 and the second visual monitoring component 5 both include a laser and a camera for detecting belt tearing, the laser in the first visual monitoring component 4 emits a light beam pointing to the front of the conveying surface of the conveyor belt 2, and the laser in the second visual monitoring component 5 emits a light beam pointing to the back of the conveying surface of the conveyor belt 2, and the laser is directed toward the conveyor belt 2. A laser is emitted, which is collected by the camera after being reflected on the surface of the conveyor belt 2, and the center of the laser stripe is automatically extracted. The height and depth parameters of the cross section of the conveyor belt 2 are analyzed through the laser stripe patterns and light reflection parameters collected by the host. When the surface parameters of the conveyor belt 2 are detected to be abnormal, the conveyor belt 2 is controlled to stop for processing. A third visual monitoring component 10 for detecting the conveying and stacking conditions of the coal gangue is installed at the top position of the coal gangue conveying channel. In addition, it also includes a lifting roller 6, which is rotatably installed in the track frame 1. The lifting roller 6 is corresponding to the conveying roller 3. The lifting roller 6 is located below the conveying roller 3 and the lifting roller 6 is in rolling contact with the conveying surface of the conveyor belt 2. The lifting roller 6 is provided with a insertion slot 61 for inserting bristles. The first visual monitoring component 4, the second visual monitoring component 5 and the third visual monitoring component 10 share a set of edge algorithm hosts.

[0038] During operation, the third visual monitoring component 10 is used to monitor in real time the accumulation height of the coal gangue transported on the upper part of the conveyor belt 2. The second visual monitoring component 5 is used to detect the belt deformation and belt tearing condition of the conveyor belt 2 when it carries coal gangue. The first visual monitoring component 4 is used to detect the belt tearing condition of the conveyor belt 2 when it is unloaded after unloading. The main engine comprehensively judges the data collected by the first visual monitoring component 4, the second visual monitoring component 5 and the third visual monitoring component 10 to judge the belt tearing condition of the conveyor belt 2. In order to avoid the recognition error caused by the adhesion of coal gangue dust, the lifting roller 6 is used to continuously clean the coal gangue bearing surface of the conveyor belt 2 during operation, thereby eliminating errors and improving the stability of the monitoring of the operation condition of the conveyor belt 2.

[0039] Machines are used to replace human eyes to measure and judge, so that what you see is what you know. A large amount of real scene image data is automatically received and intelligently analyzed and processed to achieve the positioning, detection, measurement, identification and judgment of objects. Through "perception intelligence + data processing and analysis + decision-making judgment", identification is done first and then judgment is made, and abnormal situations are actively warned.

[0040] Further, such as Figure 4 and Figure 5 As shown, a waist-shaped groove is provided at the support rod position of the track frame 1, a dust reduction block 11 is slidably installed in the waist-shaped groove, and a dust reduction spring 12 is connected between the dust reduction block 11 and the track frame 1, a dust reduction rod 13 is fixedly installed on the dust reduction block 11, the dust reduction rod 13 is located at the end position of the lifting roller 6, and the dust reduction rod 13 is "V"-shaped and extends obliquely to both sides of the lifting roller 6.

[0041] In order to further improve the dust removal effect on the surface of the conveyor belt 2, during operation, the dust reduction block 11 is maintained at a predetermined staying height on the track frame 1 under the elastic support of the dust reduction spring 12. At this time, the dust reduction rod 13 maintains a predetermined fitting distance from the surface of the conveyor belt 2. When the conveyor belt 2 moves to this area, the dust removal effect is achieved through the blocking effect of the dust reduction rod 13.

[0042] Further, such as Figures 3 to 5 As shown, the dust suppression rods 13 are provided in multiple groups, and a pair of dust suppression rods 13 in the same group are respectively located at the two end positions of the same lifting roller 6 and have opposite inclination directions. The multiple groups of dust suppression rods 13 are arranged in sequence along the conveying direction of the conveyor belt 2, and the spacing between the multiple groups of dust suppression rods 13 and the surface of the conveyor belt 2 is gradually reduced in the direction away from the coal gangue dropping point, and the surfaces of the dust suppression rods 13 are all spirally wound with annular belts.

[0043] The multiple sets of dust reduction rods 13 are gradually approached to the surface of the conveyor belt 2 by gradually increasing their height, thereby achieving a step-by-step cleaning effect of large particles attached to coal gangue. Through the inclination of the installation posture of the dust reduction rods 13 themselves, it is possible to block and clean the dust or particles while gradually transferring the cleaning object from the center position of the conveyor belt 2 to the edge position, thereby reducing the accumulation of dust or particles at the bottom of the track frame 1 during the dust removal operation, avoiding secondary pollution, and improving the stripping and cleaning effect of adsorbed stubborn particles through the spirally wound ring belt.

[0044] Further, such as Figure 6 , Fig. 9 and Fig.10 As shown, a rectangular frame-type repair bracket 7 is fixedly installed in the middle of the track frame 1, the repair bracket 7 is located between the first visual monitoring component 4 and the second visual monitoring component 5, and the return section of the conveyor belt 2 passes through the repair bracket 7, and an elastic strap 71 is fixedly installed in the middle of the repair bracket 7, the strap 71 is located above the return section of the conveyor belt 2, and thickened gaskets 72 are evenly arranged on the strap 71.

[0045] When the second visual monitoring component 5 detects that a section of the conveyor belt 2 is in an abnormal condition, the host machine marks the position of this area and records its running conveying distance. When the conveyor belt 2 in this area completes the unloading operation and passes through the lifting roller 6 area, the dust or particles on the surface of the belt are cleaned by the bristles on the lifting roller 6 and the dust removal function of the dust reduction rod 13. Subsequently, the conveyor belt 2 continues to run and passes through the position of the first visual monitoring component 4. The first visual monitoring component 4 performs a secondary inspection on the marked abnormal area on the conveyor belt 2, and compares the previous inspection results of the second visual monitoring component 5 to determine whether the conveyor belt 2 is in an abnormal condition. The tearing condition of the belt body of belt 2 is checked. Subsequently, when the conveyor belt 2 in this area runs to the position of the repair bracket 7, the main engine is shut down and staff are sent to perform on-site inspection and maintenance operations. During the maintenance, the staff pulls the strap 71 to deform it away from the conveyor belt 2 and loosens it. Subsequently, the strap 71 recovers its deformation and forms a flapping effect on the surface of the conveyor belt 2, thereby driving the conveyor belt 2 to vibrate. Through the inertial effect, accurate dust removal operations are achieved in the abnormally torn area on the surface of the conveyor belt 2. The gasket 72 set can enhance the vibration effect of the conveyor belt 2 when flapping and reduce dust residue.

[0046] Further, such as Figures 6 to 10 As shown, a plurality of follower columns 9 are rotatably installed on the track frame 1, and the plurality of follower columns 9 are distributed around the repair bracket 7. A follower rod 91 is slidably installed on the follower column 9. A serrated groove 14 is provided on the track frame 1, and the end of the follower rod 91 engages with the serrated groove 14 in an inclined state. A follower cylinder 92 is commonly installed between the two correspondingly installed follower rods 91. The follower cylinder 92 is located above the return section of the conveyor belt 2. An air groove 93 is provided on the side of the follower cylinder 92 facing the repair bracket 7. A valve port 94 connected to the air groove 93 is provided on the follower rod 91. A light belt 75 is fixedly installed on the repair bracket 7.

[0047] During the maintenance work of the conveyor belt 2, after using the binding belt 71 to remove dust from the surface of the conveyor belt 2, the light belt 75 is lit to illuminate the maintenance area. Then, the follower cylinder 92 is pulled to slide above the conveyor belt 2, and the valve port 94 is evacuated by an external air pump, thereby forming a negative pressure in the air groove 93, thereby achieving dust removal in the maintenance area of ​​the conveyor belt 2, improving the cleanliness of the maintenance space for the staff, and improving safety. In addition, by using the irradiation of the light belt 75, the maintenance personnel can judge the tearing direction of the belt according to the light-transmitting area on the conveyor belt 2. and tearing area, thereby realizing complete replacement or repair operation. After the preliminary dust suction treatment is completed, the staff rotates the follower rod 91 to make it move in an inclined posture toward the coal conveying section of the conveyor belt 2 until it fits with the conveyor belt 2. Subsequently, the bottom of the follower rod 91 is clamped to the corresponding position. At this time, the follower rod 91 and the follower cylinder 92 are used to achieve the bottom support effect of the conveying section of the conveyor belt 2, and while supporting, continuous dust suction operation is carried out in the inspection and maintenance area. The bottom support can improve the working safety and stability of the inspection and maintenance area, and avoid the falling of coal gangue caused by accidental vibration during maintenance operations.

[0048] Further, such as Figure 6 , Figure 7 and Fig. 9 As shown, a repair plate 8 is symmetrically installed in the middle of the repair bracket 7 in a hinged manner. The repair plate 8 is located below the return section of the conveyor belt 2. Plug holes are symmetrically opened at both ends of the repair bracket 7 and the repair plate 8, and latches 81 are slidably installed in the plug holes of the repair plate 8. An elastic diaphragm 73 is fixedly installed in the middle of the repair bracket 7. The diaphragm 73 is located between the two repair plates 8, and the lower half of the diaphragm 73 is in an arc shape and abuts against the side wall of the repair plate 8. The inclination angle of the repair plate 8 at its hinged position is maintained in the range of 0 to 45 degrees. A bonding strip 82 is provided at the end position of the repair plate 8. When the repair plate 8 is in a horizontal position, the bonding strip 82 contacts the front side of the conveying surface of the conveyor belt 2. A pressing plate 74 cooperating with the bonding strip 82 is provided at the end position of the repair bracket 7. The pressing plate 74 contacts the back side of the conveying surface of the conveyor belt 2. The bonding strips 82 are arranged at intervals at the ends of the repair plate 8, and a downwardly recessed arc groove is provided in the middle of the bonding strip 82.

[0049] Under normal operating conditions, the repair plate 8 stays in the repair bracket 7 in an inclined posture. When the conveyor belt 2 needs to be inspected and maintained, the staff will rotate the repair plate 8 to make it horizontal to support the bottom of the conveyor belt 2. Then, the horizontal posture of the repair plate 8 is fixed by the pin 81. At this time, under the clamping action of the bonding strip 82 and the pressure plate 74, the conveyor belt 2 located in the repair bracket 7 area is in a stationary state and its position is relatively fixed. Then, the staff will repair or replace the conveyor belt 2 in this area. During this process, the repair plate 8 acts as a repair work surface to provide flatness support during the repair process of the conveyor belt 2, thereby improving the convenience of maintenance and inspection operations.

[0050] Further, such as Fig. 9 and Fig.11 As shown, a through slot is opened in the middle of the repair plate 8, and a shaping plate 83 is slidably installed in the slot. A shaping plate 84 is fixedly installed on the side of the repair plate 8 away from the conveyor belt 2. A rotating rod 85 is installed on the shaping plate 84 by threaded cooperation. The end of the rotating rod 85 is rotatably connected to the shaping plate 83. A pointing rod 86 is slidably installed on the shaping plate 84, and the end of the pointing rod 86 is fixedly connected to the shaping plate 83.

[0051] In order to further highlight the scope of the tearing area of ​​the conveyor belt 2 and simulate the collapse under the condition of coal gangue ballasting, when the repair plate 8 is horizontally unfolded, the staff twists the rotary rod 85. Under the action of the thread, the rotary rod 85 pushes the shaping plate 83 to protrude and extend toward the upper part of the repair plate 8, and through the contact with the conveyor belt 2, the middle area of ​​the conveyor belt 2 produces a collapse deformation similar to that under the coal gangue accumulation state, thereby highlighting the scope and direction of the tearing area, which is more conducive to the judgment of the operating personnel and the subsequent repair process, improves convenience, and also improves the overall efficiency and stability of the coal conveyor belt operation and maintenance process.
