Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a water turbine lubricating cooling oil monitoring device. Background Art

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbine machinery in fluid machinery. As early as around 100 BC, China had a prototype of water turbines, which were used for irrigation and driving grain processing equipment. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, water from the upstream reservoir is led to the water turbine through a water diversion pipe, which drives the turbine runner to rotate and drives the generator to generate electricity. The water that has done work is discharged downstream through the tailwater pipe. The higher the water head and the greater the flow rate, the greater the output power of the water turbine. When the water turbine is running, a lubricating cooling oil monitoring device is required. The existing cooling oil monitoring device still has some defects, such as:

[0003] For example, the announcement number CN219911237U is an online monitoring device for fan lubricating oil, which relates to the field of lubricating oil detection system, including a monitoring unit, a lubricating oil circulation component and a cooling water circulation component. The monitoring unit is electrically connected to the lubricating oil circulation component and the cooling water circulation component. The lubricating oil circulation component includes an oil tank for fan lubrication and an electronic liquid level gauge and a thermistor sensor installed on the oil tank for detecting the oil quality in the oil tank. The electronic liquid level gauge and the thermistor sensor are electrically connected to the monitoring unit. A circulation pipeline for heat exchange is also connected to one side of the oil tank. The cooling water circulation component includes a cooling box. The circulation pipeline is connected to the inside of the cooling box. A conductivity sensor for detecting the conductivity of circulating water is also installed on the return pipe of the cooling box. The conductivity sensor is electrically connected to the monitoring unit, thereby realizing real-time monitoring of the lubricating oil condition.

[0004] The above technical solution has the following problems:

[0005] The fan lubricating oil online monitoring device is not provided with a mechanism that facilitates disassembly and assembly, which makes it inconvenient to replace parts of the fan lubricating oil online monitoring device when in use. When parts are damaged, it is troublesome to replace them, the maintenance cost is high, and the maintenance is time-consuming and labor-intensive, which increases the production cost and reduces the service life of the device;

[0006] In addition, the fan lubricating oil online monitoring device is not equipped with multiple stabilizing mechanisms, which makes it impossible for the fan lubricating oil online monitoring device to protect the parts when in use. External vibrations can easily affect the operation of the device or damage the parts, thereby increasing the maintenance frequency, increasing the maintenance cost, and reducing production efficiency.

[0007] Therefore, we propose a turbine lubrication cooling oil monitoring device to solve the above problems. Utility Model Content
