Detailed Description
The utility model discloses a distributed oil centralized detection device (which can be simply referred to as a centralized detection device), which comprises an upper computer display 30 and a plurality of ball type centralized sensor units 10 as shown in figures 1-4. The ball type centralized sensor unit comprises a bearing support 1060, an oil quality sensor 1030, an oil temperature sensor 1040, an oil level sensor 1050 and a photoelectric conversion and signal processing device 1020 which are installed on the bearing support. The signal output ends of the oil quality sensor, the oil temperature sensor and the oil level sensor are connected with the signal input end of the photoelectric conversion and signal processing device through an information exchange wire harness 1010, and collected signals are transmitted to the photoelectric conversion and signal processing device. The photoelectric conversion and signal processing device integrates the functions of multi-channel signal collection, conversion, signal processing and signal transmission. And the signal output end of the photoelectric conversion and signal processing device is used as the signal output end of the corresponding ball type centralized sensor unit and outputs information related to detection results such as oil quality, oil temperature, oil level and the like. And the signal output ends of all the ball type centralized sensor units are connected with the signal input end of the upper computer display through a line. The photoelectric conversion and signal processing device transmits the processed information to an upper computer display through a line to directly perform centralized itemized display, namely, oil quality, oil temperature and oil level detection results output by each ball type centralized sensor unit are directly displayed on the upper computer display.
The ball-type centralized sensor units can be arranged at different positions of a certain device with oil to be detected, each ball-type centralized sensor unit is equivalent to one detection point, and therefore, aiming at any parameter, the distributed oil centralized detection device can simultaneously obtain the detection results of a plurality of detection points, the real condition of the oil can be more objectively reflected, and the reliability of judging the state of the related device and the oil therein is higher according to the results. When the centralized detection device is applied to the rocker arm of the coal mining machine, even if the rocker arm of the coal mining machine is positioned at different inclination angles, accurate detection results can be obtained for the oil temperature, the oil level and the like of different chambers.
The on-site operator can judge the condition of the oil in the equipment where the distributed oil centralized detection device is located currently according to the information displayed on the upper computer display, and further judge whether the working state of the corresponding equipment is abnormal. When needed, the output end of the ball type centralized sensor unit can also be connected with an upper computer controller or a related equipment host so as to facilitate automatic judgment of the upper computer or the related equipment host according to set conditions, algorithms and the like, or the judgment can be carried out by combining the upper computer or the equipment host with manual work. According to the specific situation, the judgment can be performed by comparing the detection result of each position with the corresponding set value, or by performing certain data operation according to the detection results of a plurality of different positions to obtain a calculated value, and then comparing the calculated value with a comprehensive set value determined after comprehensively considering the weight of the influence factors of the different positions.
The centralized detection device can provide a basis for protection of related equipment under sudden working conditions. Taking the application to a rocker arm of a coal mining machine as an example, the oil quality sensor can detect iron filings in gear oil and make a signal response, and when the amount of the iron filings reaches a set value, the rocker arm motor needs to be controlled to stop. Generally, iron chips in gear oil are caused by gear damage, so that the emergency of gear damage can be timely alarmed and responded according to the detection result of the oil quality sensor. In addition, when oil leakage occurs (for example, oil leakage of a rocker cavity or oil leakage of a rocker shell due to dropping of a gear shaft end cover), the oil level is lowered, the heat dissipation and lubrication performance of the oil are correspondingly lowered, and the oil temperature is also raised, so that according to the detection result of the oil temperature sensor and/or the oil level sensor, if the abnormal condition is judged to occur, the rocker motor needs to be controlled to stop.
The fuel level sensor may employ a pressure altimetry principle sensor.
In this embodiment, the supporting frame is an elongated hollow shell structure, and the lower end of the supporting frame is hemispherical. The oil quality sensor, the oil temperature sensor and the oil level sensor are arranged at the lower end part of the hemisphere, and the photoelectric conversion and signal processing device is arranged in an inner cavity of the middle upper part of the bearing support. And information exchange wiring harnesses 1010 between the oil quality sensor, the oil temperature sensor and the oil level sensor and the photoelectric conversion and signal processing device are wired from the inner cavity of the bearing bracket.
The number of the oil sensors, the oil temperature sensors and the oil level sensors in each ball type centralized sensor unit is not limited, and the number of any one sensor can be one or more. The fuel level sender is preferably located at the lowermost end of the lower end portion of the hemisphere (i.e., at the apex of the hemisphere). The oil quality sensor is preferably as close as possible to the photoelectric conversion and signal processing device than other sensors so as to maintain a better state in terms of shortening the signal transmission distance, reducing signal interference, attenuation and the like. In this embodiment, the oil temperature sensor and the oil quality sensor are arranged on the upper edge of the hemispherical lower end part and are distributed at intervals in the circumferential direction. When a plurality of oil temperature sensors are arranged in the ball type centralized sensor unit, the positions of the oil temperature sensors are far away from each other as much as possible so as to adapt to monitoring occasions with the same detection point and different positions having larger temperature difference. In the ball type centralized sensor unit shown in fig. 2, the oil quality sensor, the oil temperature sensor and the oil level sensor are respectively provided with one, two and one, wherein the two oil temperature sensors are respectively positioned at two ends of a certain diameter at the upper edge of the lower end part of the hemisphere, and the arithmetic mean value of the detection values of the two oil temperature sensors can be taken as the oil temperature detection value of the corresponding ball type centralized sensor unit to be output.
When the ball type centralized sensor unit is installed on certain equipment, the ball type centralized sensor unit is generally vertically installed in the equipment in the state shown in fig. 2, and the lower end part of the hemisphere is ensured to be immersed in oil when the corresponding equipment is in different states or poses.

The upper computer display 30 is mounted on the body of the coal mining machine, preferably at the electric cabinet of the coal mining machine.
When the rocker arm of the coal mining machine is in various inclination angle states, the oil temperature and oil level of different chambers can be changed greatly, if the existing single-measuring-point and single-parameter monitoring is adopted, the monitoring result is usually inaccurate, but the oil centralized detection device can be used for respectively detecting multiple chambers, different chambers can set different judgment standards, and the detection result of the same parameter of each chamber can be calculated by a certain algorithm to obtain a calculation value comprehensively considering the factors such as the equipment posture, the detection point position and the like and further judge according to the calculation value, so that the corresponding detection can better meet the actual requirement.
