[0023] It should be noted that the terms “first”, “second” and the like in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or chronological order.

[0024] The terms “include” and “have” and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] The present application will be further described below in conjunction with the drawings:

[0026] As Figures 1 to 4As shown, the application provides a conveying belt detection device, which comprises a support frame 2 and a detection device body 3. The support frame 2 is adapted to be erected above the conveying belt 1. Specifically, the support frame 2 is adapted to be erected in the form of a gantry on both sides of the conveying belt 1. At least part of the support frame 2 passes above the conveying belt 1. The detection device body 3 is adapted to be arranged on the support frame 2 above the conveying belt 1. The detection device is adapted to detect the conveying belt 1 and feed back the state of the conveying belt 1 to the background central control. When an abnormality occurs, the background can timely control the conveying belt 1 to stop.

[0027] The detection device body 3 comprises a visual detection module 31 and a dust suction module 32. The visual detection module 31 identifies whether the state of the conveying material of the conveying belt 1 is normal by image acquisition of the material on the conveying belt 1 and analysis and comparison of the image, so as to identify situations such as material blocking and material piling and timely processing. It can be understood that the visual detection module 31 is prone to external environmental interference during operation. During the conveying of the material by the conveying belt 1, dust and other situations may occur, which leads to a decrease in the detection stability and accuracy of the visual detection module 31. At this time, the dust in front of the visual detection module 31 can be sucked by the dust suction module 32, so as to improve the visual field clarity in front of the visual detection module 31, thereby ensuring the detection stability and accuracy.

[0028] Specifically, the dust suction module 32 comprises an air inlet 321, an air outlet 322 and a fan 323. The air inlet 321 is arranged on the detection side of the visual detection module 31. The air outlet 322 is arranged on the non-detection side of the visual detection module 31. The fan 323 is adapted to make the air inlet 321 inhale air. The fan 323 is adapted to make the air outlet 322 exhale air. The air inlet 321 can suck the dust on the detection side of the visual detection module 31, and then discharge the dust from the non-detection side of the visual detection module 31 through the air outlet 322, so as to reduce the interference of the dust on the detection process of the visual detection module 31.

[0029] In some embodiments, the visual detection module 31 is a spectrum camera.

[0030] As shown in the embodiments of Figure 1 and 3 , the detection device body 3 comprises a temperature detection module 33. The temperature detection module 33 is arranged above the visual detection module 31. The detection direction of the temperature detection module 33 is parallel to the detection direction of the visual detection module 31. The temperature detection module 33 can detect the temperature of the material on the conveying belt 1 and the temperature around the material. When the temperature is too high, the temperature detection module 33 can send an alarm to the background, so as to control the conveying belt 1 to stop in time, thereby reducing the possibility of accidents when the high-temperature state and the dust concentration are too high.

[0031] In some embodiments, the temperature detection module 33 comprises an infrared light source receiving sensor.

[0032] As Figure 3 shown in the embodiment, the conveying belt 1 includes a coal conveying belt 12 and a coal conveying passage 11, the coal conveying belt 12 is suitable for passing through the coal conveying passage 11, the detection device body 3 is arranged above the coal conveying belt 12 at the end of the coal conveying passage 11, the detection device body 3 is suitable for detecting the state at the end of the coal conveying passage 11, and the detection device body 3 is suitable for detecting the conveying state of the coal conveying belt 12 after leaving the coal conveying passage 11. It can be understood that in the field of coal conveying equipment, the function of the coal conveying passage 11 is mainly to suppress dust raising, but due to the influence of material falling, the airflow carrying dust will be ejected from the end along the coal conveying passage 11. Although various blocking devices will be arranged in the coal conveying passage 11, if the blocking device fails, the airflow carrying dust will be extremely likely to be ejected from the coal conveying passage 11 to the external environment. In addition to being able to detect the material state on the coal conveying belt 12, the detection device can also detect the airflow state at the end of the coal conveying passage 11. When the airflow carrying dust is ejected, the visual detection module 31 can timely identify the appearance of dust and issue a reminder and an alarm, and the dust attracting module 32 can effectively reduce the dust impacting the visual detection module 31, thereby improving the detection accuracy of the visual detection module 31 and prolonging the effective detection time of the visual detection module 31 in this case.

[0033] In some embodiments, since the visual detection module 31 is easily blocked and obscured by dust, leading to detection failure, in order to further verify the occurrence of this unexpected situation, a dust concentration sensor is arranged in the dust attracting module 32. The dust concentration sensor can confirm the dust carrying state of the ejected airflow in the coal conveying passage 11 in combination with the visual detection module 31, or the dust concentration sensor can confirm the dust carrying state of the ejected airflow in the coal conveying passage 11 when the visual detection module 31 fails, so as to timely send a reminder or an alarm to the background, facilitate timely troubleshooting, and reduce accidents and losses.

[0034] As Figure 4 shown in the embodiment, the air inlet 321 is arranged below the visual detection module 31, and the direction of the air inlet 321 is parallel to the detection direction of the visual detection module 31, so that the main dust suction position of the air inlet 321 can be at the lower position in front of the visual detection module 31. When the airflow carrying dust is ejected from the coal conveying passage 11, it usually diffuses from bottom to top. Therefore, the air inlet 321 can first perform the operation of attracting dust, thereby reducing the dust diffused to the visual detection module 31.

[0035] As Figure 4In the embodiment shown, a first guide section 3211 is provided on the side of the air inlet 321 near the vision inspection module 31. The first guide section 3211 is adapted to guide the dust on the upper front side of the vision inspection module 31 into the air inlet 321. The first guide section 3211 is used to guide the airflow on the upper front side of the vision inspection module 31 into the air inlet 321. By increasing the flow rate, the dust on the upper front side of the vision inspection module 31 is more easily sucked in.

[0036] like Figure 4 In the embodiment shown, a second guide section 3212 is provided on the side of the air inlet 321 away from the vision detection module 31. The second guide section 3212 is adapted to guide the dust on the lower front side of the vision detection module 31 into the air inlet 321. The second guide section 3212 is used to guide the airflow on the lower front side of the vision detection module 31 into the air inlet 321. By increasing the flow rate, the dust on the lower front side of the vision detection module 31 is more easily sucked in.

[0037] like Figure 4 In the embodiment shown, the first guide section 3211 and the second guide section 3212 are arc-shaped structures. The arc area of ​​the first guide section 3211 is larger than the arc area of ​​the second guide section 3212. Since the visual inspection module 31 is above the air inlet 321, a greater guiding effect is needed above the air inlet 321 to reduce the dust that diffuses to the visual inspection module 31.

[0038] like Figure 2 In the embodiment shown, the air outlet 322 is located on the bottom side of the vision inspection module 31 away from the inspection side. The air outlet 322 is adapted to discharge the dust sucked in by the air inlet 321 to the conveyor belt 1 below. The dust discharged from the air outlet 322 can be discharged to the conveyor belt 1, reducing its diffusion in the external environment and improving the environmental protection effect.

[0039] In some embodiments, the fan 323 is a centrifugal fan. The fan 323 is arranged close to the rear of the vision inspection module 31, which makes the structure more compact, reduces the overall volume, and facilitates the arrangement.
