Description

Technical Field

[0001] This utility model belongs to the field of oil level sensor technology, and in particular relates to a monitoring device for an online oil monitoring module. Background Technology

[0002] An oil level sensor is a device used to detect the height of a liquid level. Capacitive oil level sensors, as one type, are based on the principle of capacitance. By detecting changes in capacitance, the oil level can be determined.

[0003] Oil level sensors play an important role in the detection of oil in the gearbox of electric locomotives. However, when using existing oil level sensors, high-viscosity oil may adhere to or accumulate on the surface of the sensor electrodes, affecting the capacitance change between the electrodes and the medium, resulting in inaccurate measurement results.

[0004] Therefore, it is necessary to improve the existing oil level sensors. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a monitoring device for an online oil monitoring module, which improves the detection accuracy of the oil level sensor.

[0006] To achieve the above objectives, the specific technical solution of the monitoring device of the online oil monitoring module of this utility model is as follows:

[0007] A monitoring device for an online oil monitoring module includes a main body and a probe rod fixedly connected to each other. Multiple guide rods are arranged on the main body along the extension direction of the probe rod, and each guide rod is distributed around the axis of the probe rod. Each guide rod has a protrusion. A sliding member is slidably engaged with each guide rod, and the sliding member is connected to a striking block via an elastic connector. When the sliding member slides along the guide rod under buoyancy, the striking block and the protrusion collide with each other.

[0008] Preferably, a threaded sleeve is provided on the side of the main body near the probe rod, and the threaded sleeve is threadedly connected to an installation ring. The top end of each guide rod is fixedly connected to the installation ring, and the bottom end of each guide rod is fixedly connected to each other.

[0009] Preferably, each of the guide rods has multiple protrusions, and the protrusions are evenly distributed along the extension direction of the guide rod.

[0010] Preferably, the sliding element is a buoyancy ring, and the probe and each of the guide rods are disposed through the buoyancy ring, the buoyancy ring having a hollow, sealed inner cavity.

[0011] Preferably, the inner wall of the buoyancy ring is provided with a guide groove that slides with the guide rod.

[0012] Preferably, the striking block is spherical in shape.

[0013] Preferably, a filter screen is provided between two adjacent guide rods, and the main body and each of the filter screens enclose a cavity for accommodating the probe rod.

[0014] Preferably, the buoyancy ring is coaxially and detachably connected to an annular cleaning brush.

[0015] Preferably, the main body is provided with a sealing cap.

[0016] The monitoring device of the online oil monitoring module of this utility model has the following advantages: When the sliding member slides along the guide rod, the striking block and the protrusion collide with each other, causing the oil level sensor to vibrate. This causes the oil adhering to the probe rod to fall off under the action of vibration, thereby keeping the probe rod clean and improving the detection accuracy of the oil level sensor. The sliding member moves along the guide rod under the action of oil buoyancy, eliminating the need for an additional drive mechanism to provide power, reducing the production cost of the oil level sensor, and improving the energy-saving performance of the oil level sensor.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the oil level sensor and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] like Figure 1-3 As shown, a monitoring device for an online oil monitoring module includes a main body 101 and a probe 102 fixedly connected to each other. Multiple guide rods 202 are arranged on the main body 101 along the extension direction of the probe 102. Each guide rod 202 is distributed around the axis of the probe 102, and each guide rod 202 is provided with a protrusion 204. A sliding member is slidably engaged with the guide rod 202. The sliding member is connected to a striking block 302 through an elastic connector 303. When the sliding member slides along the guide rod under the action of buoyancy, the striking block and the protrusion collide with each other.

[0026] This oil level sensor is suitable for detecting the oil level in the gearbox of electric locomotives. During use, the sensor needs to be installed vertically so that the probe 102 extends into the oil. The oil level is detected by the change in capacitance between the electrodes of the probe 102. The guide rod 202 supports the sliding member, allowing it to slide along the guide rod 202. The elastic connector 303 is a spring. As the sliding member slides along the guide rod 202, the elasticity of the elastic connector 303 causes the striking block 302 to repeatedly impact the protrusion 202. When the two collide, the probe 102 vibrates, reducing oil adhesion to the probe 102, improving its cleanliness, and thus enhancing the detection accuracy of the oil level sensor.

[0027] Compared with existing oil level sensors, the sliding component floats on the surface of the oil under the buoyancy of the oil. During the operation of the electric locomotive, the oil flows inside the gearbox, thereby driving the sliding component to slide along the guide rod 202. This eliminates the need for an additional power mechanism for the sliding component, reducing the production cost of the oil level sensor and improving its energy-saving effect.

[0028] Further improvements include, for example Figure 2 As shown, a threaded sleeve 104 is provided on the side of the main body 101 near the probe rod 102. The threaded sleeve 104 is threadedly connected to the mounting ring 201. The top end of each guide rod 202 is fixedly connected to the mounting ring 201, and the bottom end of each guide rod 202 is fixedly connected to each other.

[0029] Specifically, after fixing the ends of each guide rod 202, the guide rods 202 are assembled into a whole, thereby improving the firmness of each guide rod 202. The threaded sleeve 104 is connected to the mounting ring 201 by threads, which makes it easy to remove the mounting ring 201 from the main body 101, thereby improving the ease of disassembly and assembly of the guide rods 202 and the ease of maintenance of the oil level sensor.

[0030] Further improvements include, for example Figure 3 As shown, each guide rod 202 has multiple protrusions 204, and each protrusion 204 is evenly distributed along the extension direction of the guide rod 202.

[0031] Specifically, the multiple protrusions 204 can repeatedly collide with the striking block 302, thereby generating continuous vibration when the sliding member moves, which improves the cleaning effect on the oil adhering to the probe rod 102.

[0032] Further improvements include, for example Figure 4 As shown, the sliding element is a buoyancy ring 301, and the probe rod 102 and each guide rod 202 are all installed through the buoyancy ring 301. The buoyancy ring 301 has a hollow, sealed inner cavity.

[0033] Specifically, the hollow buoyancy ring 301 can float better on the surface of the oil, and can reduce the weight of the buoyancy ring 301, improve the driving ability of the oil on the buoyancy ring 301, and make the buoyancy ring 301 slide more smoothly.

[0034] Further improvements include, for example Figure 4 As shown, the inner wall of the buoyancy ring 301 is provided with a guide groove 304 that slides with the guide rod 202.

[0035] Specifically, the guide groove 304 and the guide rod 202 cooperate with each other to achieve mutual limiting between each guide rod 202 and the buoyancy ring 301, improve the stability of the connection of each component, thereby improving the stability of the buoyancy ring 301 when it moves and reducing the failure rate of the oil level sensor.

[0036] Further improvements include, for example Figure 4 As shown, the striking block 302 is spherical in shape.

[0037] Specifically, when the striking block 302 contacts the protrusion 204, the spherical structure is smoother, which reduces the resistance generated when the two come into contact, so that the buoyancy ring 301 can slide smoothly along the guide rod 202.

[0038] Further improvements include, for example Figure 2 As shown, a filter screen 203 is provided between two adjacent guide rods 202, and the main body 101 and each filter screen 203 enclose a cavity for accommodating the probe rod 102.

[0039] When the oil level sensor is in use, impurities may be present inside the gearbox oil. These impurities mix with the oil, affecting its dielectric constant. Changes in the dielectric constant directly affect the capacitance value, thus impacting measurement accuracy. To address this, a filter 203 is installed to remove impurities from the oil, keeping it clean. This minimizes changes in the oil's dielectric constant, allowing the probe 102 to more accurately detect the oil level, improving the sensor's detection accuracy. Furthermore, filtering out impurities by the filter 203 reduces their adhesion to the probe 102, slowing its wear and further enhancing the sensor's measurement accuracy and extending its lifespan.

[0040] Further improvements include, for example Figure 5 As shown, the buoyancy ring 301 is coaxially and detachably connected to an annular cleaning brush 305.

[0041] Specifically, the cleaning brush 305 is connected to the buoyancy ring 301 by bolts, which facilitates the disassembly and replacement of the cleaning brush 305. During the movement of the buoyancy ring 301, the bristles of the cleaning brush 305 can clean the filter screen 203, reducing the chance of the filter screen 203 becoming clogged, allowing the oil to pass through the filter screen 203 more smoothly, ensuring that the oil level is consistent inside and outside the filter screen 203, thereby improving the accuracy of the oil level sensor.

[0042] Further improvements include, for example Figure 2 As shown, the main body 101 is provided with a sealing cover 103.

[0043] Specifically, the sealing cover 103 can be installed at the opening of the gearbox. While covering the gearbox opening, it can achieve mutual fixation between the oil level sensor and the gearbox, improving the ease of installation of the oil level sensor on the gearbox.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
