Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and specifically to an underground conveying device based on sonar monitoring. Background Art

[0002] As is well known, belt conveyors are one of the important electrical equipment in coal mining enterprises. Belt conveyors have the advantages of long transportation distance, large transportation capacity, small working resistance, easy installation, low power consumption, and less wear. The length of belt conveyors in coal mine shafts is relatively long (long belt conveyors can reach dozens of kilometers). When the belt conveyor is transporting coal, it may be damaged, and regular inspections by workers are required. This regular inspection method for belt conveyors is rather cumbersome.

[0003] Sonar is a technology that uses the propagation and reflection characteristics of sound waves in the air to detect through electro-acoustic conversion and information processing. It also refers to the technology of detecting targets (existence, position, nature, movement direction, etc.) and the detection effect using this technology. Then, sonar and electronic equipment analyze and process the monitored data. Sonar is an important means to observe and measure the belt conveyor through sound waves.

[0004] For example, in the patent with the publication number CN117800039B and the publication date of May 14, 2024, titled "Belt Deviation Detection System for Belt Conveyor", this patent relates to a belt deviation detection system for belt conveyors and belongs to the technical field of conveyor detection. It includes a belt conveyor body. Slide rails are fixedly connected to both sides of the belt conveyor body. Slide shoes are slidably connected inside the slide rails. An inverted U-shaped suspension is fixedly connected between the two slide shoes. The middle of the bottom surface of the suspension is fixedly connected with an infrared and visible light fusion device. The infrared and visible light fusion device is electrically connected to a computing device. A fault discovery area is provided on each side of the belt of the belt conveyor body. A number of copper alloy wires are embedded in the belt in the fault discovery area, and the copper alloy wires are fixed in the belt through vulcanized glue. This patent provides a belt deviation detection system that can obtain the precursor information of belt deviation and overcomes the drawback of the existing detection method having hysteresis.

[0005] The deficiencies of the prior art are that the inspection of belt conveyors often relies on inspection workers to regularly walk along the belt conveyor and discover problems through means such as visual inspection, listening, and knocking. The time consumed for one inspection is long, and the limited energy of workers leads to a high false detection rate, low efficiency, and the inability to trace the root cause of problems in real time. Once the operator fails to detect a damaged bearing in time, the long-term friction causes the belt conveyor to catch fire, resulting in equipment shutdown and heavy losses. For existing belt conveyors with a length in the range of dozens of kilometers, there is a lack of a global, automated, and intelligent belt inspection system. Summary of the Invention

[0006] The object of the present invention is to provide an underground conveying device based on sonar monitoring to solve the technical problems in the related art.

[0007] To achieve the above object, the present invention provides the following technical solution: An underground conveying device based on sonar monitoring, including a belt conveyor body for conveying coal, and further including a monitoring unit. The monitoring unit includes a sonar body. A plugging slot is opened at the bottom end of the belt conveyor body, and a positioning rod is plugged and installed in the plugging slot. The sonar body is fixedly installed on the positioning rod. The detachable installation between the sonar body and the belt conveyor body is realized through the plugging and positioning of the positioning rod and the plugging slot.

[0008] As described above, the belt conveyor body includes a frame body and a conveyor belt body. A plurality of conveying rollers are installed between the inner walls of the frame body in a rotational fit manner, and the conveyor belt body is jointly installed between the conveying rollers.

[0009] As described above, a plurality of support rollers are evenly arranged between the top side walls of the frame body in a rotational fit manner, and each support roller performs a supporting operation on the conveyor belt body.

[0010] As described above, a plurality of auxiliary rollers are evenly arranged between the bottom side walls of the frame body in a rotational fit manner.

[0011] As described above, the plugging slot is opened on the outer side wall of the frame body, a blocking block is arranged in the plugging slot, and a locking rod is rotatably arranged on the positioning rod.

[0012] As described above, a right-angle groove is opened on the locking rod, and the right-angle groove and the blocking block are arranged in mutual cooperation.

[0013] As described above, a square groove is opened on the positioning rod.

[0014] As described above, an auxiliary round rod is arranged in the plugging slot, and a square rod is arranged on the auxiliary round rod.

Detailed implementation manners

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will further introduce the present invention in detail in conjunction with the attached drawings Figure 1 to Figure 18 attached drawings.

[0040] An embodiment provided by the present invention relates to an underground conveying device based on sonar monitoring, including a belt conveyor body for conveying coal, and also including a monitoring unit, wherein the monitoring unit includes a sonar body 1, and a plug-in groove 2 is opened at the bottom end of the belt conveyor body, a positioning rod 3 is plugged and installed in the plug-in groove 2, and the sonar body 1 is fixedly installed on the positioning rod 3, and the detachable installation between the sonar body 1 and the belt conveyor body is realized by plugging and positioning the positioning rod 3 and the plug-in groove 2.

[0041] Specifically, the belt conveyor body is a device for transporting coal underground. The belt conveyor body can transport coal out of the mine. During the use of the belt conveyor, gear damage, oil shortage, bearing burning, falling off and other problems are often encountered. Therefore, it is necessary to monitor the faults of the belt conveyor in time. The sonar body 1 passively receives the noise generated on the belt conveyor body to determine the direction of the damaged target of the belt conveyor body. The sonar body 1 can collect the noise generated on the belt conveyor body, and then analyze and track the sound wave data obtained on the sonar body 1 through a computer. Different types of sounds are automatically judged as prior art. No further details are given. The sonar body 1 collects abnormal noise on the belt conveyor body. The belt conveyor body includes a frame 4 and a conveyor belt body 5. A plurality of conveying rollers 6 are installed between the inner walls of the frame 4 in a rotating manner. Each of the conveying rollers A conveyor belt body 5 is installed between the rollers 6; a plurality of support rollers 7 are evenly arranged between the top side walls of the frame body 4 in a rotationally matched manner, and each of the support rollers 7 supports the conveyor belt body 5; a plurality of auxiliary rollers 8 are evenly arranged between the bottom side walls of the frame body 4 in a rotationally matched manner, and a plurality of support rods (not shown in the figure) are evenly arranged at the bottom end of the frame body 4, and the frame body 4 is supported by the support rods. It can be known to those skilled in the art that a power mechanism is arranged on the frame body 4, and the power mechanism is used to drive the conveyor rollers 6 to rotate, so that the conveyor rollers 6 can drive the conveyor belt body 5 to rotate, so that the conveyor belt body 5 can transport the coal, and each support roller 7 provides support for the conveyor belt body 5 to transport the coal, so that the conveyor belt body 5 can stably transport the coal, and the conveyor belt body 5 forms an inward concave structure (such as Figure 8As shown), to prevent coal from leaking from the side of the conveyor belt body 5, each auxiliary roller 8 performs auxiliary support operation for the bottom of the conveyor belt body 5, so that the conveyor belt body 5 is in a taut state to prevent the conveyor belt body 5 from breaking. It is common knowledge in the field that the belt conveyor body transports coal through the conveyor belt body 5, conveying rollers 6, support rollers 7 and auxiliary rollers 8, and will not be repeated. However, the belt conveyor body may be damaged when transporting coal. When the belt conveyor body is damaged, it will emit abnormal noise. A sonar body 1 is arranged on the belt conveyor body to collect abnormal noise on the belt conveyor body, so as to timely and accurately determine the damaged position of the belt conveyor body, which is convenient for the staff to timely repair. The existing technology for detecting the belt conveyor body is that the staff patrols by visual, auditory, knocking and other means Inspection work is performed, but this inspection method consumes a long time and has limited human energy, resulting in a high false detection rate. In this embodiment, the insertion slot 2 and the positioning rod 3 are plugged in and adapted to each other to achieve the quick insertion and installation of the positioning rod 3 and the sonar body 1 on the frame 4. By installing the sonar body 1 on the frame 4, the abnormal noise on the belt conveyor body is analyzed and the location of the abnormal noise is determined, so that the staff can determine the location of the abnormal noise on the belt conveyor body. The staff can promptly perform maintenance work on the location of the abnormal noise on the belt conveyor body to prevent major accidents. It is known to those skilled in the art that a plurality of insertion slots 2 can be evenly opened at the bottom of the frame 4 to achieve the insertion and positioning of a plurality of positioning rods 3 and the insertion slots 2 to achieve the detachable installation between the sonar body 1 and the belt conveyor body.

[0042] The shortcomings of the existing technology are that the inspection of belt conveyors often relies on inspection workers to regularly walk along the belt conveyor and find problems through visual, auditory, and knocking methods. The inspection takes a long time and the human energy is limited, resulting in a high false detection rate, low efficiency, and the inability to trace the root cause of the problem in real time. Once the operator fails to find the damaged bearing in time, the long-term friction will cause the belt conveyor to catch fire, causing the equipment to stop working and causing heavy losses. The existing belt conveyors are tens of kilometers long and lack a global, automated, and intelligent belt inspection system.

[0043] The beneficial effect of this embodiment is that the sonar body 1 is installed on the belt conveyor body through the positioning rod 3, and the sonar body 1 is fixedly installed on the belt conveyor body so that the sonar body 1 can collect the noise generated on the belt conveyor body, and then the sound wave data obtained on the sonar body 1 is analyzed and tracked by a computer, and the noise is analyzed to determine the direction of the damaged target of the belt conveyor body and release a signal, so that the staff can know the damaged position of the belt conveyor body in time and carry out repairs.

[0044] Preferably, the insertion slot 2 is formed on the outer side wall of the frame body 4. A stopper 9 is arranged in the insertion slot 2, and a locking rod 10 is rotatably arranged on the positioning rod 3. A right-angle groove 11 is formed on the locking rod 10, and the right-angle groove 11 and the stopper 9 are arranged in a matching manner. A square groove 12 is formed on the positioning rod 3. An auxiliary round rod 13 is arranged in the insertion slot 2, and a square rod 14 is arranged on the auxiliary round rod 13. A spring body 15 is sleeved on the outer wall of the auxiliary round rod 13. The square rod 14 is inserted into the square groove 12.

[0045] Specifically, when the sonar body 1 needs to be installed on the frame body 4, the staff inserts the positioning rod 3 into the insertion slot 2. During the process of inserting the positioning rod 3 into the insertion slot 2: when the positioning rod 3 is inserted into the insertion slot 2, under the action of the self-gravity of the locking rod 10, the locking rod 10 and the positioning rod 3 are perpendicular to each other, and the right-angle groove 11 on the locking rod 10 and the stopper 9 are on the same side. When the positioning rod 3 gradually enters the insertion slot 2, the locking rod 10 and the stopper 9 are in mutual contact, and the locking rod 10 is blocked by the stopper 9 and rotates on the positioning rod 3, so that the locking rod 10 and the positioning rod 3 are parallel to each other (as Figure 5 shown), until the right-angle groove 11 on the locking rod 10 overlaps with the stopper 9. Synchronously, the square rod 14 and the auxiliary round rod 13 are inserted into the square groove 12 on the positioning rod 3, and the positioning rod 3 squeezes the spring body 15 (i.e., a device with elastic force, such as a helical spring), so that the spring body 15 provides elastic support for the positioning rod 3. At this time, the staff releases the thrust on the positioning rod 3. Under the rebounding action of the spring body 15, the spring body 15 pushes the positioning rod 3 to move towards the outer end of the insertion slot 2 until the right angle of the right-angle groove 11 on the locking rod 10 abuts tightly against the stopper 9. Since the right angle of the right-angle groove 11 on the locking rod 10 abuts tightly against the stopper 9, the stopper 9 positions the locking rod 10, and the stopper 9 and the locking rod 10 insert the positioning rod 3 into the insertion slot 2 (as Figure 3 shown), so that the positioning rod 3 and the sonar body 1 can be quickly installed on the frame body 4, and the sonar body 1 can be stably installed on the frame body 4 through the mutual insertion and cooperation of the positioning rod 3 and the insertion slot 2; when the sonar body 1 needs to be removed from the frame body 4, the staff pushes the positioning rod 3 to move towards the inner end of the insertion slot 2, and the positioning rod 3 drives the locking rod 10 to move towards the inner end of the insertion slot 2 on the stopper 9 until the locking rod 10 and the stopper 9 are separated from each other. After the locking rod 10 and the stopper 9 are separated from each other, under the action of the self-gravity of the locking rod 10, the locking rod 10 rotates on the positioning rod 3, so that the locking rod 10 and the positioning rod 3 are perpendicular to each other (as Figure 4As shown, synchronously, the positioning rod 3 squeezes the spring body 15. After the locking rod 10 and the stopper 9 are disengaged from each other, the staff releases the thrust on the positioning rod 3. Under the resilience of the spring body 15, the spring body 15 pushes the positioning rod 3 to move towards the outer end of the insertion slot 2. The positioning rod 3 drives the locking rod 10 to move from the top end of the stopper 9, so that the positioning rod 3 and the locking rod 10 can be taken out of the insertion slot 2, and the sonar body 1 can be taken out from the frame body 4, enabling the sonar body 1 to be detachably installed on the frame body 4.

[0046] In another embodiment provided by the present invention, a hollow groove 21 is provided on the frame body 4. A flat rod 22 is slidably arranged in the hollow groove 21. An auxiliary circular groove 16 is formed on the flat rod 22. A threaded groove 17 is formed on the inner wall of the auxiliary circular groove 16 along its circumferential direction. A driven circular rod 18 is rotatably installed in the auxiliary circular groove 16. A passive circular rod 19 is arranged on the outer wall of the driven circular rod 18. The passive circular rod 19 is slidably installed in the threaded groove 17. A driven groove 20 is formed at the top end of the driven circular rod 18. A plurality of grooves 23 are evenly formed on the flat rod 22 along its circumferential direction. A first wedge-shaped block 24 is slidably installed in each of the grooves 23. A first elastic member 25 is connected between each of the first wedge-shaped blocks 24 and the inner wall of the corresponding groove 23. A plurality of straight grooves 26 are evenly formed on the inner wall of the hollow groove 21. A second wedge-shaped block 27 is slidably installed in each of the straight grooves 26. And a wedge-shaped fit is provided between each of the first wedge-shaped blocks 24 and the corresponding second wedge-shaped block 27. A square frame groove 28 is formed on the frame body 4, and the square frame groove 28 is connected to each of the straight grooves 26. A square frame 29 is slidably installed in the square frame groove 28. The square frame 29 is connected to each of the second wedge-shaped blocks 27. A plurality of second elastic members 30 are evenly arranged between the square frame 29 and the square frame groove 28. A switch plate 31 is arranged on the square frame 29 at the outer side of the frame body 4. A plurality of clamping rods 32 are evenly arranged at the bottom of the flat rod 22 in a sliding fit manner. A flat plate 33 is commonly installed at the bottom ends of the clamping rods 32. The sonar body 1 is installed on the flat plate 33. The bottom end of the driven circular rod 18 is rotatably installed on the flat plate 33.

[0047] Specifically, when the sonar body 1 needs to be installed on the frame 4, the staff inserts the flat rod 22 into the hollow groove 21. Since the first wedge-shaped blocks 24 are arranged in the grooves 23 on the flat rod 22, the flat rod 22 can drive each first wedge-shaped block 24 to slide into the hollow groove 21. The first wedge-shaped blocks 24 move towards the inner end of the groove 23 under the extrusion of the hollow groove 21, so that the first wedge-shaped blocks 24 perform extrusion operations on the first elastic members 25 (the first elastic members 25 are components that can be telescopically reset, preferably springs), causing the first elastic members 25 to be in a compressed state until the flat rod 22 drives each first wedge-shaped block 24 to move to the straight groove 26 position. When the first wedge-shaped blocks 24 move to the straight groove 26 position, under the rebounding action of the first elastic members 25, the first elastic members 25 push the first wedge-shaped blocks 24 to slide into the straight groove 26, so that the first wedge-shaped blocks 24 perform positioning operations on the flat rod 22 in the straight groove 26. Synchronously, under the pulling force of the second elastic members 30 (the second elastic members 30 are components that can be telescopically reset, preferably springs), the second elastic members 30 pull the square frame 29 so that the second wedge-shaped blocks 27 on the square frame 29 and the first wedge-shaped blocks 24 are arranged in a wedge-shaped fit with each other, enabling the first wedge-shaped blocks 24 to insert and install the flat rod 22 in the hollow groove 21. Since the passive round rod 19 is slidably installed in the threaded groove 17, the threaded groove 17 has a certain positioning effect on the passive round rod 19, enabling the driven round rod 18 to perform a certain positioning operation on the flat plate 33, so that the sonar body 1 installed on the flat plate 33 can be stably installed in the hollow groove 21 through the flat rod 22, realizing the stable installation of the sonar body 1. Those skilled in the art can know that the sonar body 1 is fixedly connected (such as welding) to the flat plate 33, so that the sonar body 1 can be stably installed on the flat plate 33 and move synchronously with the flat plate 33.

[0048] When the sonar body 1 needs to be removed from the frame 4, the staff uses a tool to press the switch plate 31 outside the frame 4, so that the switch plate 31 drives the square frame 29 to slide towards one end close to the first wedge-shaped block 24 in the square frame groove 28, so that the square frame 29 drives each second wedge-shaped block 27 to move synchronously towards one end close to the first wedge-shaped block 24. Since the second wedge-shaped blocks 27 and the first wedge-shaped blocks 24 are arranged in a wedge-shaped fit with each other, the second wedge-shaped blocks 27 push the first wedge-shaped blocks 24 to slide out of the straight groove 26, so that the first wedge-shaped blocks 24 and the straight groove 26 are disengaged from each other. Then the staff takes out the flat rod 22 from the hollow groove 21, so that the flat rod 22 and the sonar body 1 are taken out from the hollow groove 21, realizing the removal of the sonar body 1 from the frame 4.

[0049] In another embodiment provided by the present invention, a driven gear 34 is rotatably provided at the top end of the hollow groove 21. A driving rod 35 is provided on the driven gear 34. The driving rod 35 and the driven groove 20 at the top end of the driven round rod 18 are inserted and matched with each other, so that the driving rod 35 can drive the driven round rod 18 to rotate through the driven groove 20. A sliding groove 36 is formed at the top of the hollow groove 21 on the frame body 4. A driven rack 37 is slidably installed in the sliding groove 36. The driven rack 37 and the driven gear 34 are meshed with each other. One end of the driven rack 37 is provided with a hollow rod 38. A sliding rod 39 is slidably installed in the hollow rod 38. The sliding rod 39 penetrates through the hollow rod 38. Third wedge-shaped blocks 40 are respectively arranged at both ends of the sliding rod 39 located in the hollow rod 38. A fourth wedge-shaped block 41 is arranged on the bottom side of the conveyor belt body 5. The third wedge-shaped block 40 and the fourth wedge-shaped block 41 are wedge-shaped and matched with each other. Two insertion slots 42 are formed on the inner wall of the hollow rod 38. The distance between the two insertion slots 42 is the same as the sliding distance of the wedge-shaped fit between the third wedge-shaped block 40 and the fourth wedge-shaped block 41. A flat groove 43 is formed on the sliding rod 39. A plug rod 44 is slidably installed in the flat groove 43. The plug rod 44 and the inner wall of the flat groove 43 are connected by a third elastic member 45. The plug rod 44 and the insertion slot 42 are inserted and matched with each other. The end of the plug rod 44 is in an isosceles trapezoid shape. The side wall of the flat groove 43 and the end of the plug rod 44 are wedge-shaped and matched with each other. A relief ring groove is formed on the outer wall of each conveying roller 6. The relief ring groove is used to make way for the conveyor belt body 5 to drive the fourth wedge-shaped block 41 to rotate synchronously, so that the fourth wedge-shaped block 41 can pass through the conveying roller 6.

[0050] Specifically, since the position of the sonar body 1 on the frame 4 is relatively fixed, there may be certain data anomalies when the sonar body 1 collects noise at the same position all the time. Therefore, it is necessary to adjust the position of the sonar body 1 on the frame 4 at intervals to ensure the accuracy of the noise data collected by the sonar body 1. Since the conveyor belt body 5 has been performing coal conveying operations, the conveyor belt body 5 drives the fourth wedge block 41 to move. Since relief ring grooves (not shown in the figure) are provided on the outer walls of the respective conveyor rollers 6, the fourth wedge block 41 can pass through the conveyor roller 6 from the position of the relief ring groove. When the fourth wedge block 41 moves to the position of the third wedge block 40, due to the mutual plug-in setting between the insertion rod 44 and the slot 42, the sliding rod 39 is positioned in the hollow rod 38. During the process of the conveyor belt body 5 driving the fourth wedge block 41 to move, the fourth wedge block 41 drives the third wedge block 40 to move, so that the third wedge block 40 drives the driven rack 37 to slide in the sliding groove 36. Since the driven rack 37 and the driven gear 34 are meshed with each other, the driven rack 37 can drive the driven gear 34 to rotate clockwise, so that the driven gear 34 drives the driving rod 35 to rotate. Since the driving rod 35 and the driven groove 20 at the top of the driven round rod 18 are mutually plugged and matched, the driving rod 35 can drive the driven round rod 18 to rotate through the driven groove 20. Since the passive round rod 19 is provided on the outer wall of the driven round rod 18 and the passive round rod 19 is slidably installed in the threaded groove 17, the passive round rod 19 is driven to rotate during the rotation of the driven round rod 18. Since the passive round rod 19 is slidably installed in the threaded groove 17, the passive round rod 19 can move along the track of the threaded groove 17, so that the passive round rod 19 drives the driven round rod 18 to move away from the driven gear 34 at one end in the auxiliary circular groove 16. Since the driven round rod 18 is rotatably installed on the flat plate 33 and a plurality of clamping rods 32 are uniformly arranged at the bottom of the flat rod 22 in a sliding fit manner, and the bottom ends of the respective clamping rods 32 are jointly installed with a flat plate 33, the driven round rod 18 can drive the flat plate 33 to move away from the driven gear 34 at one end, and the flat plate 33 drives the sonar body 1 to move away from the driven gear 34 at one end until the fourth wedge block 41 drives the third wedge block 40 and the driven rack 37 to slide to the end of the sliding groove 36, so that the driven rack 37 no longer slides, and the fourth wedge block 41 and the third wedge block 40 are mutually wedge-fitted, so that the fourth wedge block 41 forcibly pushes the third wedge block 40 to move to one end at the bottom of the conveyor belt body 5 (that is, the end away from the driven gear 34 or the end away from the support roller 7), so that the third wedge block 40 drives the sliding rod 39 to move away from the driven gear 34 at one end in the hollow rod 38. Synchronously, the sliding rod 39 drives the insertion rod 44 to move from the slot 42 near the driven gear 34 to the slot 42 away from the driven gear 34. Under the elastic force of the third elastic member 45 (the third elastic member 45 is an element capable of telescopic reset, preferably a spring),Enable the third elastic member 45 to push the plug rod 44 to move into the slot 42, so that the plug rod 44 can position the sliding rod 39 after sliding, so that the sliding rod 39 can be in a positioned state within the hollow rod 38. When the fourth wedge block 41 drives the third wedge block 40 and the driven rack 37 to slide to the end of the sliding groove 36, the passive round rod 19 slides to the end of the stroke of the thread groove 17 (i.e., the bottom of the thread groove 17), so that the passive round rod 19 and the driven round rod 18 drive the flat plate 33 and the sonar body 1 to move to the end of the stroke away from one end of the driven gear 34, so that the flat plate 33 and the sonar body 1 are at the bottommost end on the frame 4. At this time, the flat plate 33 and the sonar body 1 are in a positioned state, and the sonar body 1 collects and processes abnormal noises on the belt conveyor body.

[0051] When the fourth wedge block 41 abuts against the third wedge block 40 from one end at the bottom of the conveyor belt body 5 (i.e., the end of the fourth wedge block 41 away from the support roller 7 or the end close to the auxiliary roller 8), the fourth wedge block 41 drives the third wedge block 40 to move. The third wedge block 40 drives the driven rack 37 to slide in the sliding groove 36, so that the driven rack 37 can drive the driven gear 34 to rotate counterclockwise, and the driven gear 34 drives the driving rod 35 to rotate. The driving rod 35 drives the driven round rod 18 to rotate through the driven groove 20. The driven round rod 18 drives the driven round rod 19 to move along the track of the thread groove 17, so that the driven round rod 19 drives the driven round rod 18 to move towards one end close to the driven gear 34 in the auxiliary round groove 16, so that the driven round rod 18 can drive the flat plate 33 to move towards one end close to the driven gear 34. The flat plate 33 drives the sonar body 1 to move towards one end close to the driven gear 34 until the fourth wedge block 41 drives the third wedge block 40 and the driven rack 37 to slide to the end of the sliding groove 36, so that the driven rack 37 no longer slides. The fourth wedge block 41 and the third wedge block 40 are in wedge fit with each other, so that the fourth wedge block 41 forcibly pushes the third wedge block 40 towards one end at the top of the conveyor belt body 5 (i.e., the end close to the driven gear 34 or the end close to the support roller 7), so that the third wedge block 40 drives the sliding rod 39 to move towards one end close to the driven gear 34 in the hollow rod 38. Synchronously, the sliding rod 39 drives the insertion rod 44 to move from the insertion slot 42 at the end away from the driven gear 34 to the insertion slot 42 at the end close to the driven gear 34. Under the elastic force of the third elastic member 45, the third elastic member 45 can push the insertion rod 44 into the insertion slot 42, so that the insertion rod 44 can position the sliding rod 39 after sliding, so that the sliding rod 39 can be in a positioned state in the hollow rod 38. When the fourth wedge block 41 drives the third wedge block 40 and the driven rack 37 to slide to the end of the sliding groove 36, the driven round rod 19 slides to the end of the stroke of the thread groove 17 (i.e., the top of the thread groove 17), so that the driven round rod 19 and the driven round rod 18 drive the flat plate 33 and the sonar body 1 to move to the end of the stroke close to the driven gear 34, so that the flat plate 33 and the sonar body 1 are at the topmost position on the frame 4. At this time, the flat plate 33 and the sonar body 1 are in a positioned state, and the sonar body 1 collects and processes abnormal noises on the belt conveyor body. Through the movement of the conveyor belt body 5 and the fourth wedge block 41, the position of the sonar body 1 on the frame 4 can be changed when the conveyor belt body 5 rotates half a circle. Especially when the sonar body 1 detects abnormal noises, and the conveyor belt body 5 does not stop moving, the conveyor belt body 5 can change the detection position of the sonar body 1 through the fourth wedge block 41. When the sonar body 1 detects abnormal noises emitted from the same position at two different positions, it indicates that the belt conveyor body is damaged, and the staff needs to carry out maintenance and repair in time, ensuring the safety of the operation of the belt conveyor body.
