[0024] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1 To be continued Figure 4 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0025] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] Example 1: An oil quality detection module for a hydraulic station, comprising:

[0027] Oil storage tank 1, with a detection port connected to the inside of oil storage tank 1 on one side, and an oil outlet pipe 101 installed on the detection port.

[0028] Specifically, the oil storage tank 1 includes a high-temperature tank 102 and a low-temperature tank 103. The high-temperature tank 102 is located on one side of the low-temperature tank 103, and the detection port is located on the side wall of the low-temperature tank 103. The bottom of the high-temperature tank 102 and the low-temperature tank 103 are provided with an integrally formed base 104. A row of connecting pipes 105 is provided between the high-temperature tank 102 and the low-temperature tank 103, and the two ends of the connecting pipes 105 are respectively connected to the interior of the high-temperature tank 102 and the low-temperature tank 103.

[0029] The entire oil storage tank 1 has improved structural stability and reduced vibration interference through an integrally molded base 104. The hydraulic oil can be stored in separate zones. The high-temperature tank 102 is used to directly connect to an external hydraulic system. The high-temperature hydraulic oil in the high-temperature tank 102 is not used for testing and sampling. The low-temperature tank 103 is used to store the cooled hydraulic oil at room temperature. The two are connected by a connecting pipe 105 to achieve oil transportation. The detection port is located on the side wall of the low-temperature tank 103, and oil samples can be extracted from this port.

[0030] The oil testing unit includes an oil inlet pipe 2, a testing base pipe 3, an oil outlet pipe 4, and a laser testing module. The oil inlet pipe 2 is connected to the oil outlet pipe 101 of the oil tank. The testing base pipe 3 is located between the oil inlet pipe 2 and the oil outlet pipe 4. The testing base pipe 3 is a transparent square pipe. The laser testing module is located on the outside of the testing base pipe 3, and the laser testing path in the laser testing module passes through the testing base pipe 3.

[0031] Specifically, the laser detection module includes a transmitter 5 and a receiver 6, which are respectively located on both sides of the detection base tube 3. The transmitter 5 includes a transmitter base 501, a sensor mounting block 502, a laser sensor 503, and a mounting cover 504. The transmitter base 501 is located on one side of the detection base tube 3, and the sensor mounting block 502 is located on the upper end of the transmitter base 501. There are two sets of laser sensors 503, which are located inside the sensor mounting block 502. The number of mounting covers 504 corresponds to the number of laser sensors 503. The mounting covers 504 are fixed to the upper end of the sensor mounting block 502 by screws. The receiver 6 includes a receiver base 601, a mounting plate 602, and a receiver 603. The receiver base 601 is located on the other side of the detection base tube 3, the mounting plate 602 is fixedly located between the receiver bases 601, and the receiver 603 is located at the front end of the mounting plate 602.

[0032] When the oil flows through the detection base tube 3, the transmitter 5 emits a laser, and the receiver 6 analyzes the signal attenuation and provides real-time feedback on the oil data. The detection base tube 3 is a transparent square tube used for oil to flow through and receive laser detection. The entire laser detection module consists of two parts: the transmitter 5 and the receiver 6. The transmitter 5 emits a laser that passes through the detection base tube 3, and the receiver 6 captures the laser signal after it has passed through the detection base tube 3. The transmitter 5 and the receiver 6 work together to analyze the oil quality in real time, that is, to judge the oil deterioration by the changes in laser scattering and transmission. This non-contact detection method can avoid contaminating the oil circuit. The transparent square tube itself reduces optical distortion and improves the detection quality. Two sets of laser sensors 503 are set, and multiple parameters can be set for synchronous monitoring of the two sets of sensors. For example, one set of laser sensors 503 detects turbidity, and the other set of laser sensors 503 detects particle concentration.

[0033] A first solenoid valve 7 is installed between the detection oil inlet pipe 2 and the oil tank outlet pipe 101. A return oil pipe 12 is installed at the other end of the detection oil outlet pipe 4. A second solenoid valve 8 is installed at one end of the return oil pipe 12. The other end of the second solenoid valve 8 is connected to the inside of the oil storage tank 1. An oil outlet port is installed at the top of the low temperature chamber 103. An oil extraction pipe 10 is installed at the oil outlet port. A third solenoid valve 9 is installed in the oil extraction pipe 10.

[0034] A pressure sensor 11 is installed at the upper end of the return oil pipe 12.

[0035] In the above three sets of solenoid valves, the first solenoid valve 7 controls the detection of oil inlet, the second solenoid valve 8 controls the return oil, and the third solenoid valve 9 controls the main system oil outlet. The pressure sensor 11 monitors the pressure of the return oil pipe 12. When the first solenoid valve 7 is opened, the oil sample enters the detection base pipe 3, and returns to the oil storage tank 1 through the detection oil outlet pipe 4 and the second solenoid valve 8. When the third solenoid valve 9 is opened, the oil in the cryogenic chamber 103 is supplied to the hydraulic system through the oil extraction pipe 10. When the oil quality is poor, the third solenoid valve 9 cuts off the oil outlet passage of the cryogenic chamber 103.

[0036] The above description is a further detailed explanation of the present utility model in conjunction with specific embodiments, and it should not be considered that the specific implementation of the present utility model is limited to this. For those skilled in the art to which the present utility model pertains and related fields, any extensions, operation methods, and data substitutions made based on the technical solution concept of the present utility model should fall within the protection scope of the present utility model.
