[0030] Specifically, such as Figure 1As shown, a first oil inlet 211 is provided on a side surface of the shell 21 adjacent to the heat exchanger 22, and a second oil outlet 212 is further provided below the first oil inlet 211. A first oil outlet 221 and a second oil inlet 222 are provided on one side surface of the heat exchanger 22. The first oil outlet 221 and the second oil inlet 222 are respectively located at two opposite corners on the same side of the heat exchanger 22; a water inlet 223 is provided at a position adjacent to the second oil inlet 222, and a water outlet 224 is provided at a position adjacent to the first oil outlet 221.

That is, the water inlet 223, the water outlet 224, the first oil outlet 221, and the second oil inlet 222 are respectively located at the four corners on the same side surface of the heat exchanger 22. The first oil inlet 211 is connected to the first oil outlet 221 via a first oil pipe 26, and the second oil inlet 222 is connected to the second oil outlet 212 via a second oil pipe 27. The output end of the pumping motor 23 is connected to the second oil outlet 212 and the second oil inlet 222, respectively, via a second oil pipe 27, allowing the pumping motor 23 to extract lubricating oil from the housing 21 through the second oil pipe 27. An L-shaped partition 28 is provided between the pumping motor 23 and the heat exchanger 22. Both the pumping motor 23 and the heat exchanger 22 are secured to the outer surface of the housing 21 via the partition 28. Furthermore, a first bearing and a second bearing are sleeved on the outer surface of the input shaft 24. The first bearing is located on the side of the housing 21 near the heat exchanger 22, and the second bearing is located on the side of the housing 21 away from the heat exchanger 22.

[0031] In conjunction with the above, an oil temperature sensor 4 is disposed at the bottom of the housing 21 and is used to monitor the temperature of the lubricating oil in the gearbox 2. An electric heater 8 is disposed at the bottom of the housing 21 near the oil temperature sensor 4 and is used to heat the lubricating oil. A water saturation sensor 3 is disposed on the first oil pipe 26 and is used to monitor the water saturation of the lubricating oil. A filter 5 is disposed on the second oil pipe 27 and is used to filter impurities in the lubricating oil. A first bearing temperature sensor 6 is disposed on the housing 21 near the first bearing and in contact with the first bearing, and a second bearing temperature sensor 7 is disposed on the housing 21 near the second bearing and in contact with the second bearing. The first bearing temperature sensor 6 is used to monitor the temperature of the first bearing, and the second bearing temperature sensor 7 is used to monitor the temperature of the second bearing.

[0032] In summary, combined Figures 1 to 3The principle of the present invention is as follows: when the gear box 2 is ready to start working, the temperature of the lubricating oil in the housing 21 is first monitored by the oil temperature sensor 4. When the temperature is detected to be lower than 0°C, the signal is transmitted to the electric control box 1, and the electric control box 1 controls the electric heater 8 to heat the lubricating oil; when the oil temperature sensor 4 detects that the lubricating oil is heated to above 0°C, the signal is transmitted to the electric control box 1, and the electric control box 1 controls the electric heater 8 to be turned off. Only then can the gear box 2 be started and work can be carried out, effectively avoiding damage to the gears caused by the cold start of the gear box 2.

[0033] After the gearbox 2 is started, the gears begin to work and the internal temperature gradually rises. When the oil temperature sensor 4 detects that the lubricating oil temperature rises to above 65°C, it transmits a signal to the electronic control box 1; the electronic control box 1 controls the oil pumping motor 23 to start working, and the oil pumping motor 23 pumps the lubricating oil in the shell 21 through the second oil pipe 27 and transmits it to the heat exchanger 22; the heat exchanger 22 inputs cooling water through the water inlet 223 to heat and cool the lubricating oil, and discharges the used cooling water from the water outlet 224. When the lubricating oil is cooled to below 55°C, it is input into the shell 21 again through the first oil pipe 26, and the oil pumping motor 23 is controlled to stop working by the electronic control box 1, thereby achieving the effect of real-time control of the lubricating oil temperature, so that the lubricating oil temperature is always maintained in the optimal range of 55°C-65°C, ensuring that the gearbox 2 is always in the best working condition.

[0034] As lubricating oil is transferred into housing 21 through first oil pipe 26, water saturation sensor 3 monitors the water saturation of the lubricating oil in first oil pipe 26 in real time. When the water saturation of the lubricating oil exceeds the specified level, a signal is transmitted to electrical control box 1, causing indicator light 13 on electrical control box 1 to illuminate and issue an alarm, prompting staff to promptly replace the lubricating oil to prevent emulsification and the impact of lubricating oil on the normal operation of gearbox 2. As lubricating oil is transferred into heat exchanger 22 through second oil pipe 27, filter 5 removes impurities from the lubricating oil in second oil pipe 27. When impurities in filter 5 become clogged, filter element 51 transmits a signal to electrical control box 1, causing indicator light 13 on electrical control box 1 to illuminate and issue an alarm, prompting staff to promptly replace filter element 51 and remove impurities.

[0035] When the gearbox 2 is operating normally, if the first bearing temperature sensor 6 or the second bearing temperature sensor 7 detects that the temperature of the first bearing or the second bearing is too high, a signal will be sent to the electric control box 1, and the indicator light 13 of the electric control box 1 will light up and issue an alarm, reminding the staff to check the first bearing or the second bearing in time to avoid damage caused by excessive temperature. If the first bearing or the second bearing is found to be damaged after inspection, it needs to be replaced in time to avoid affecting the normal operation of the gearbox 2.

[0036] It can be seen that the utility model discloses a lubricating oil monitoring system for monitoring a gear box, comprising an electronic control box and a moisture saturation sensor. The electronic control box is electrically connected to the moisture saturation sensor through a water control line. The electronic control box is used to monitor the gear box and alarm. The moisture saturation sensor is used to monitor the moisture saturation of the lubricating oil in the gear box. The gear box comprises a shell and a heat exchanger arranged on the outer surface of the shell. A first oil inlet is provided on a side surface of the shell adjacent to the heat exchanger. A first oil outlet is provided on one side surface of the heat exchanger. The first oil inlet is connected to the first oil outlet through a first oil pipe. The moisture saturation sensor is arranged on the first oil pipe. The present application sets a water saturation sensor on the first oil pipe of the gear box, and cooperates with the electronic control box to monitor the water saturation of the lubricating oil in the first oil pipe in real time when the gear box and the heat exchanger are working; when the water saturation exceeds the predetermined standard, the electronic control box will alarm to remind the staff to replace the lubricating oil in time, thereby avoiding the problem of water content in the lubricating oil exceeding the standard, which will damage the oil film, cause the additive to fail, and cause corrosion of the metal parts inside the gear box, effectively extending the service life of the gear box, reducing economic losses, and improving the safety of the gear box operation process.
