[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific diagrams.

[0026] The intelligent monitoring system for power equipment provided in this solution is a device applied to the silent box of the generator set, which integrates multiple functions such as coolant detection, fuel detection, engine oil detection, waste liquid collection and discharge, etc. All maintenance work is integrated into one interface operation. The status of coolant, fuel, engine oil and waste liquid can be detected and maintained through the monitoring system and maintenance system.

[0027] Specifically, the intelligent monitoring system of the power equipment in this solution includes a monitoring and maintenance system, a control system, a coolant treatment module, a fuel treatment module, an engine oil detection module and a waste liquid treatment module.

[0028] Further, see Figure 1-Figure 3 The coolant processing module is composed of a cooling water level maintainer 110 and a water heater 120. Through the cooperation of the cooling water level maintainer 110, the water heater 120 and the control system, the observation and detection of the coolant position, the replenishment and heating of the coolant can be realized.

[0029] Specifically, the cooling water level maintainer 110 is used in conjunction with a water level detector; the water level detector is connected to a monitoring and maintenance system; and the cooling water level maintainer 110 is connected in conjunction with a control system.

[0030] Among them, the cooling water level maintainer 110 is connected with the engine water tank 130, which can measure the height of the liquid in the engine water tank 130 and transmit the measured data to the monitoring and maintenance system in the form of electrical signals; the monitoring and maintenance system drive control system controls the cooling water level maintainer 110 to replenish the coolant in the engine water tank 130 through the water filling port 140.

[0031] The detection scheme of the liquid level in the engine water tank 130 is not limited here. As an example, the U-tube principle can be adopted to measure the pressure difference between the two tubes of the U-tube. If the liquid level in the engine water tank 130 is lower than the set value, a pressure difference will be generated between the two tubes of the U-tube. At this time, the monitoring and maintenance system will give an alarm signal after receiving the data, prompting to add water. The engine water tank 130 will be replenished with coolant through the control system until the pressure values ​​in the U-tube are the same.

[0032] At the same time, the cooling water level maintainer 110 is provided with a balancing air pipe 111 for balancing the air pressure inside the cooling water level maintainer 110 and the external air pressure to improve stability during operation; in addition, the cooling water level maintainer 110 is also provided with an air vent pipe 112 for discharging excess air introduced into the cooling water level maintainer 110.

[0033] The water heater 120 is used to heat the coolant, and is cooperatively connected with the water tank 100 .

[0034] The water heater 120 is used in conjunction with a temperature detector. The temperature detector in the water heater 120 is connected to the monitoring and maintenance system; the temperature detector can measure the temperature of the coolant transmitted from the water tank 100 to the engine water tank 130, and transmit the measured data to the monitoring and maintenance system.

[0035] When the temperature of the coolant in the engine water tank 130 sensed by the temperature sensor is lower than the set value, the water heater 120 is started by the control system to heat the coolant, and the heated coolant is transmitted to the engine water inlet.

[0036] The coolant can be heated by the water heater 120, which can improve the reliability of engine starting when used in high-cold areas.

[0037] Furthermore, the fuel processing module includes a fuel-air detector 210 , an oil-water separator 220 , a fuel-water specific gravity detector 230 , and a fuel level sensor 330 .

[0038] The fuel level sensor 330 is used to detect the liquid level value of the fuel in the fuel tank, and is connected to the monitoring and maintenance system for data.

[0039] The fuel level sensor 330 is connected with the fuel tank 200 to measure the height of the liquid in the fuel tank 200 and transmit the measured data to the monitoring and maintenance system in the form of an electrical signal; the fuel in the fuel tank can be replenished through the fuel filling port 350.

[0040] The fuel air detector 210 can detect the air discharge from the fuel line.

[0041] The fuel air detector 210 is connected to the fuel pipeline on the fuel tank 200; when the fuel tank 200 transports fuel through the fuel pipeline, the fuel air detector 210 detects the air in the pipeline and simultaneously drives the exhaust valve 211 to discharge excess air.

[0042] A heating plug 212 is also provided on the fuel air detector, and the fuel is heated by the heating plug 212 on the fuel air detector 210 to prevent the fuel from waxing when used in high-altitude cold areas.

[0043] In this solution, three oil-water separators 220 are connected in parallel to form an oil-water pre-filtration structure. The exhausted or heated fuel is pre-filtered through the oil-water separator 220, and the pre-filtered fuel is transmitted to the fuel water specific gravity detector 230.

[0044] The fuel water specific gravity detector 230 is used to detect the water content in the input fuel; it is connected to the oil-water separator 220 and the waste liquid tank 400 respectively.

[0045] The fuel water specific gravity detector 230 detects the water content of the input fuel. If the water content exceeds the set value, the solenoid valve 231 is opened to discharge the water into the waste liquid tank 400, thereby separating and discharging the water in the fuel. The separated fuel is transported to the engine through a pipeline.

[0046] Furthermore, the engine oil processing module includes an engine oil level maintainer 310 and an engine oil quality observer 320. The engine oil level maintainer 310 and the engine oil quality observer 320 cooperate with each other to realize the replenishment and replacement of the engine oil.

[0047] The oil level maintainer 310 is used to replenish the oil in the oil tank in time; the oil level maintainer 310 is connected to the monitoring and maintenance system; and is connected to the control system.

[0048] The oil level maintainer 310 is connected with the oil tank to measure the height of the liquid in the oil tank and transmit the measured data to the monitoring and maintenance system in the form of electrical signals.

[0049] The control system controls the oil level maintainer 310. If the oil level in the oil tank is lower than the set value, the monitoring and maintenance system gives an alarm signal to prompt refueling. The control system then drives the oil level maintainer 310 to transfer the oil in the supplementary tank or the new tank to the oil tank.

[0050] The detection scheme of the oil level in the oil tank is not limited here. As an example, the U-tube principle can be adopted to measure the pressure difference between the two tubes of the U-tube. If a pressure difference occurs between the two tubes, the oil is replenished into the oil tank through the control system.

[0051] The oil quality observer 320 is used to observe the state of the engine pan. If the oil in the engine pan is unqualified, the data is transmitted to the monitoring and maintenance system. The control system can drive the oil pump 340 to extract the oil from the engine pan and transmit it to the filter box. The oil is synchronously delivered to the engine pan through the oil level maintainer 310 to realize the oil change function.

[0052] In addition, the fuel tank is connected to a pipeline between an electric pre-supply pump 360 and a second one-way valve 362. The electric pre-supply pump 360 draws fuel from the fuel tank through the second one-way valve 362. After the fuel is pressurized by the electric pre-supply pump 360, it flows to the fuel-air detector 210, or flows to the fuel-air detector 210 through the second pipeline first one-way valve 361 for fuel-air detection, etc.

[0053] The waste liquid treatment module includes a waste liquid tank 400 and a number of pipelines; one end of each of the pipelines is connected to the waste liquid tank 400, and the other end is respectively connected to the coolant treatment module, the fuel treatment module and the engine oil treatment module; the waste gas, waste liquid, water and impurities generated in the coolant treatment module, the fuel treatment module and the engine oil treatment module are transmitted to the waste liquid tank 400 through the pipelines.

[0054] A liquid pump 410 is provided on the pipeline of the waste liquid tank 400, and a liquid level detector is provided inside. When the liquid level detector detects that the waste liquid tank 400 is almost full, the liquid pump 410 is driven by the control system to discharge the waste liquid in the waste liquid tank.

[0055] The following example illustrates its working process in a specific application:

[0056] See also Figure 4 First, the coolant maintainer 110 detects the liquid level in the water tank, and controls the water tank to replenish the coolant into the engine water tank 130 through the control system; if the temperature of the coolant is lower than the set value, the control system drives the water heater 120 to heat the cooling water delivered to the engine water inlet.

[0057] Secondly, the fuel in the fuel tank 200 enters the pipeline, and the excess air in the pipeline is first discharged through the exhaust valve 211 by the fuel air detector 210, and then the fuel is pre-filtered for oil-water separation by the oil-water separator 220; the pre-filtered fuel is filtered again by the fuel-water specific gravity detector 230, and the fuel with excessive water content is separated from the oil, and the excess water, waste oil and impurities are discharged to the waste liquid tank 400; the filtered fuel is transported to the engine.

[0058] In addition, the oil quality observer 320 observes the oil in the engine oil pan. If the oil quality in the engine oil pan is unqualified, the oil in the engine oil pan is extracted through the oil pump 340 and transported to the filter box with filtration; at the same time, the oil level maintainer 310 replenishes oil into the engine oil pan through the control system and transports it to the engine oil pan.

[0059] The intelligent monitoring system for power equipment formed by the above scheme integrates all maintenance work into one working interface, and can realize the processing of coolant, fuel, engine oil and waste liquid on one interface, thereby greatly improving work efficiency.
