TECHNICAL FIELD

[0001] The present application relates to the field of EH fire-resistant oil, in particular to an electrochemical sensing device for online monitoring of EH fire-resistant oil. BACKGROUND

[0002] At present, the EH fire-resistant oil system is the main control component of the action of thermal power machinery equipment, and it is necessary to monitor the state of the fire-resistant oil quality and pollution. Early detection of particle pollution, water pollution, and abnormal high temperature of the fire-resistant oil can effectively improve the reliability of the bearing and the hydraulic system, and ensure the safe operation of the unit.

[0003] However, the existing fire-resistant oil detection is usually directly connected with a sensing device on the fire-resistant oil pipeline for detection, which affects the flow rate of the fire-resistant oil. In addition, the fire-resistant oil does not need to be detected all the time, which affects the normal use of the fire-resistant oil. Moreover, the existing detection device is not firm enough, and the detection device will shake with the oil detection guide pipe when the vehicle moves. CONTENT OF THE UTILITY MODEL

[0009] Preferably, the electric control valve is fixed with a timing switch on one side, and the timing switch is used to control the opening and closing of the electric control valve.

[0010] By adopting the technical scheme, the electric control valve is controlled by the timing switch, the timing switch controls the opening of the electric control valve, and the electric control valve is automatically closed after the timing switch controls the opening of the electric control valve for a period of time.

[0011] Preferably, the first extrusion plate and the second extrusion plate are both fixed with a first connecting block at the top, and a through hole is formed in the middle of the first connecting block.

[0012] By adopting the technical scheme, the two first connecting blocks are fixed by using the threads and nuts to pass through the first connecting blocks of the first extrusion plate and the second extrusion plate, so that the first extrusion plate and the second extrusion plate are fixed to the outer wall of the main conduit.

[0013] Preferably, the first extrusion plate and the second extrusion plate are both arranged in a hollow semicircular ring shape, and the first extrusion plate and the second extrusion plate are connected by a hinge seat at the bottom.

[0015] Preferably, the Bluetooth transmitter is provided with a USB interface at the top, and the Bluetooth transmitter is used to connect with an external Bluetooth receiver.

[0016] By adopting the technical scheme, after long-term use, the detection signal recorded by the Bluetooth transmitter can be transmitted through the USB structure, which is convenient for judging the long-term use of the fire-resistant oil.

[0017] In summary, the present application has the following at least beneficial technical effects:

[0018] 1. The present application controls the electric control valve through the timing switch, the timing switch controls the opening of the electric control valve, and the electric control valve is automatically closed after the timing switch controls the opening of the electric control valve for a period of time, so that when detection is needed, the part of the fire-resistant oil opened by the electric control valve can enter the secondary conduit for detection, and after the detection is completed, the electric control valve is closed, which does not affect the normal oil guiding of the main conduit, thereby achieving the effect of reducing the influence of the normal use of the fire-resistant oil, and the detection device can be quickly fixed.

[0019] 2. In this application, the first and second extrusion plates are attached to the main tube. By using threads and nuts to pass through the first connecting blocks of the first and second extrusion plates, the two first connecting blocks are fixed, thereby fixing the first and second extrusion plates to the outer wall of the main tube. Subsequently, by rotating the threaded sleeve rod to change the distance between the two ends of the threaded rod and the threaded sleeve rod, the secondary tube and the main tube with different distances can be adapted, so that the main tube can support the secondary tube well and keep the secondary tube horizontal, thereby achieving the effect of convenient and firm device fixation.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0026] This application discloses an electrochemical sensing device for online monitoring of EH fire-resistant oil, including a main tube 1. A secondary conduit 2 is connected through the top of one side of the main tube 1. The secondary conduit 2 is U-shaped. An electrically controlled valve 8 is fixed at one end of the secondary conduit 2 at the interface with the main tube 1. A support tube 17 is movably sleeved on the outer wall of the secondary conduit 2. A threaded rod 16 is fixed at the bottom of the support tube 17. A threaded sleeve 15 is rotatably connected to the outer wall of the threaded rod 16. By rotating the threaded sleeve 15, the distance between the two ends of the threaded rod 16 and the threaded sleeve 15 can be changed to adapt to different distances between the secondary conduit 2 and the main tube 1, so that the main tube 1 can effectively support the secondary conduit 2 and maintain the horizontal state of the secondary conduit 2. This allows for better detection. The outer wall of the main tube 1 is detachably equipped with a first extrusion plate 10 and a second extrusion plate 11. A second connecting block 14 is fixed to the top of the middle part of the second extrusion plate 11. The second connecting block 14 is rotatably connected to the threaded sleeve rod 15. A wire 5 is sealed and connected through the middle of the secondary tube 2. A Bluetooth transmitter 3 is fixed to the top of the wire 5. A connecting rod 6 is fixed to the bottom of the wire 5. A sensor 7 is fixed to the bottom of the connecting rod 6. The sensor 7 detects the fire-resistant oil inside the secondary tube 2 and then transmits the signal through the wire 5 to the Bluetooth transmitter 3. The Bluetooth transmitter 3 connects to an external Bluetooth receiver and displays real-time data on an external display screen.

[0027] Reference Appendix Figure 4 The system includes six sensors 7, which, from left to right, are a viscosity sensor, a moisture sensor, a temperature sensor, an acid value sensor, a dielectric sensor, and a contaminant sensor. Viscosity is the resistance between molecules when a liquid flows under external force; it is used to evaluate the fluidity of the liquid. Reducing the water content of EH fire-resistant oil can significantly extend the fatigue life of rolling bearings. Dielectric constant is an indicator reflecting the overall quality of the oil.

[0028] Reference Appendix Figure 1 and 2 The electric valve 8 is equipped with a timer switch 9 on one side. The timer switch 9 is used to control the opening and closing of the electric valve 8 at regular intervals. The electric valve 8 is opened by the timer switch 9 at regular intervals, and then automatically closes after the electric valve 8 has been open for a period of time.

[0029] Reference Appendix Figure 3 The first extrusion plate 10 and the second extrusion plate 11 are both fixed with a first connecting block 13 at their top. The first connecting block 13 has a through hole in the middle. By using threads and nuts to pass through the first connecting block 13 of the first extrusion plate 10 and the second extrusion plate 11, the two first connecting blocks 13 are fixed, thereby fixing the first extrusion plate 10 and the second extrusion plate 11 to the outer wall of the main tube 1.

[0030] Reference AppendixFigure 3 The first extrusion plate 10 and the second extrusion plate 11 are both hollow semi-circular rings, and the bottoms of the first extrusion plate 10 and the second extrusion plate 11 are connected by a hinge seat 12. The semi-circular first extrusion plate 10 and the second extrusion plate 11 can fit better with the main tube 1 through the hinge seat 12, and can be adapted to use with main tubes 1 of different sizes.

[0031] Reference Appendix Figure 4 The Bluetooth transmitter 3 has a USB interface 4 on its top. The Bluetooth transmitter 3 is used to connect to an external Bluetooth receiver. After long-term use, the detection signal recorded by the Bluetooth transmitter 3 can be transmitted through the USB interface 4, which is convenient for judging the overall long-term use condition of the fuel.

[0032] The implementation principle of an electrochemical sensing device for online monitoring of EH fire-resistant oil according to an embodiment of this application is as follows: First, a semi-circular first extrusion plate 10 and a second extrusion plate 11 are placed on both sides of the main tube 1, and rotated by the hinge seat 12. The first extrusion plate 10 and the second extrusion plate 11 fit against the main tube 1. By using threads and nuts passing through the first connecting blocks 13 of the first extrusion plate 10 and the second extrusion plate 11, the two first connecting blocks 13 are fixed, thereby fixing the first extrusion plate 10 and the second extrusion plate 11 to the outer wall of the main tube 1. Subsequently, by rotating the threaded sleeve 15, the distance between the threaded rod 16 and the two ends of the threaded sleeve 15 is changed to adapt to the secondary conduit 2 and the main tube 1 with different distances, so that the main tube 1 can provide good support for the secondary conduit 2. Maintaining the secondary conduit 2 in a horizontal position, the electronically controlled valve 8 is opened by a timer switch 9. The timer switch 9 controls the electronically controlled valve 8 to open at regular intervals, and after a period of time, the electronically controlled valve 8 automatically closes. This allows the fire-resistant oil to partially enter the secondary conduit 2 for testing when necessary. After entering, the electronically controlled valve 8 closes, without affecting the normal oil flow of the main conduit 1. The fire-resistant oil is detected by a viscosity sensor, a moisture sensor, a temperature sensor, an acid value sensor, a dielectric sensor, and a contaminant sensor. Sensor 7 detects the fire-resistant oil inside the secondary conduit 2 and then transmits the signal through wire 5 to a Bluetooth transmitter 3. The Bluetooth transmitter 3 connects to an external Bluetooth receiver, and real-time data is displayed on an external screen.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
