Description

Technical Field

[0001] The present invention relates to the technical field of noise monitoring equipment, and in particular provides a noise monitoring equipment for mining. Background Art

[0002] In the mining sector, noise pollution has become a key factor restricting the industry's development. Operations such as rock drilling, blasting, and machinery operation generate high-intensity noise (80-120 decibels or even higher).

[0003] However, the current construction of smart mines focuses more on scheduling and operation management systems, and there are still deficiencies in the research and development of intelligent equipment and safety risk warning and detection technologies for actual working conditions. Especially in the noise monitoring link, the mining area has complex terrain and a large area. Fixed monitoring points have coverage blind spots. Mobile monitoring by manual inspections poses safety risks and is difficult to achieve continuous monitoring. The noise generated by the operation of unmanned inspection equipment itself further exacerbates the complexity of noise source identification and monitoring. Therefore, there is an urgent need to develop a new type of equipment that integrates automatic mobile monitoring, drone remote sensing collaboration, and intelligent dust reduction to achieve full coverage and high-precision monitoring of mine noise and dust environments, and promote the development of the mining industry.

The suppression buffer 344 is a magnetorheological shock absorber. A position sensor is installed at the bottom end of the intermediate longitudinal plate 362, away from the mounting vertical plate 331, for monitoring the position of the limit block 371.

A visual monitoring probe and an acoustic probe are installed at the bottom of the monitoring drone 47.

[0042] For example, in one embodiment: before monitoring driving, the rotating motor 31 is started, thereby driving the longitudinal rotator 32 to rotate, and then the adjusting connecting plate 33, the suppressing element 34, the adjusting linkage element 35 and the two spraying elements 38 follow the movement until the adjusting abutting wheel 356 is located in the middle of the front wheel of the mobile body 10, and its direction is the same as the forward direction of the front wheel. Then, the longitudinal rotator 32 is started, so that the suppressing spray barrel 343 and the adjusting abutting wheel 356 are abutted on the ground, and then the monitoring driving is started. At the same time, the atomizing equipment will start and form a dust suppression spray to be transported to the suppression spray barrel 343 and the two conical sprayers 382, ​​so that the dust suppression spray flows out from the suppression spray barrel 343 and the two conical sprayers 382 to reduce dust in the forward direction of the mobile vehicle 10. At the same time, the two acoustic noise sensors 22 and the bottom vibration acoustic noise sensor will continuously collect mine noise on the move to obtain multi-dimensional information of the noise, and link the microphone array panel 14 to comprehensively process the signals from different sensors to improve the signal-to-noise ratio and recognition accuracy of the noise signal. The time difference measurement technology (TDOA) is used to measure the time difference or phase difference between the sound waves reaching each sensor, combined with the sound source positioning algorithm (such as beamforming, time difference estimation, sound intensity measurement, etc.) to calculate the spatial position of the noise source, realize the estimation and dynamic tracking of the noise source direction, realize the separation and identification of multiple sound sources, clarify the specific location of the noise, detect abnormal noise in time, and assist mine safety management and environmental protection.

[0043] For example, in one embodiment, when the vehicle encounters an undulating terrain, the terrain will cause the suppression spray barrel 343 to follow the movement, thereby causing the suppression frame 342 and the suppression shaft 341 to follow the rotation and movement, causing the mounting inclined plate 345 to follow the rotation and movement, causing the suppression buffer 344 to follow the movement. At this time, since the adjustment abutment wheel 356 is located at the rear and has not yet contacted the undulating terrain, the movement of the suppression buffer 344 will compress the inclined abutment slide plate 365 to move, causing the two elastic curved strips 346 to deform, causing the elastic curved strips 346 to follow the movement, thereby pulling the push-pull vertical strip 372 to follow the movement, and thus The adjustment slide 354 follows the movement, the adjustment slide 354 follows the movement, the push spring 373 follows the movement, the push bent plate 374 is pushed, the two spray elements 38 are pushed, the two spray racks 381 rotate outward and expand, the two conical sprayers 382 follow the movement, and the dust reduction spray sprayed by the conical sprayers 382 is sprayed outward synchronously. At the same time, the position sensor will send a signal to the atomizing device to increase the spraying volume of the atomizing device to ensure that there will be no excessive dust during movement, and to prevent dust from adhering to the bottom vibration acoustic noise sensor and the acoustic noise sensor 22. At the same time, the position sensor will send signals to the two telescopic adjustment cylinders 21, the monitoring rotating motor 23, the bottom rotating motor 25 and the suppression buffer 344, so that the damping of the magnetorheological fluid in the suppression buffer 344 will decrease, making the suppression buffer 344 "soft", and reducing the shock of the undulating terrain passed by, and starting the telescopic adjustment cylinder 21 to retract the telescopic adjustment cylinder 21, so that the acoustic noise sensor 22 follows the movement and becomes tilted. At the same time, the bottom rotating motor 25 will start, so that the bottom vibration acoustic noise sensor moves synchronously, changing the detection position of the acoustic noise sensor 22 and the bottom vibration acoustic noise sensor, and preventing the movement noise from affecting the collection of noise monitoring.

[0044] For example, in one embodiment: when the terrain of the mine is too undulating or even has a "cliff-like" change, or when drilling, blasting, mining, transportation, soil discharge and other operations are being carried out, and it is inconvenient to move the vehicle body 10 to enter, the clamping motor 464 is started, driving the two ruler bars 462 to move outward, so that the two clamping charging seats 465 follow the movement, and the clamping of the monitoring drone 47 disappears. At the same time, the monitoring drone 47 will be started to perform remote sensing monitoring of the mining area.

[0045] When the monitoring drone 47 completes the monitoring, the clamping motor 464 will start again, causing the two clamping charging seats 465 to clamp the monitoring drone 47 inward. At the same time, the two-axis conveyor 43 will also start, and the transport plug-in component 48 will move toward the plug-in connector 45, so that the plug-in rack 481 is covered on one of the plug-in connectors 45, and the connecting sliding head 483 is inserted into the plug-in connector 45 to supply electricity to the monitoring drone 47.
