Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0029] The following reference Figures 1 to 6 The present application describes an oil moisture detector 100 according to some embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this application proposes an oil moisture detector 100, comprising: a body 110, the body 110 including a cavity; an oil storage tank 120 disposed in the cavity, the oil storage tank 120 storing the oil to be tested; a mounting box 130 disposed in the cavity and spaced apart from the oil storage tank 120, the mounting box 130 having a first assembly port 132 on its side wall; a sensor disposed in the first assembly port 132 for detecting the oil in the oil storage tank 120; a pressure cap 150 detachably disposed on the outside of the mounting box 130, the pressure cap 150 having a second assembly port 152 corresponding to the first assembly port 132, the sensor being clamped and fixed between the mounting box 130 and the pressure cap 150 through the first assembly port 132 and the second assembly port 152; and a flow guiding assembly 160, one end of the flow guiding assembly 160 being connected to the sensor, and the other end of the flow guiding assembly 160 being connected to the oil storage tank 120.

[0031] The oil moisture detector 100 provided in this application includes a main body 110, an oil reservoir 120, a mounting box 130, a sensor, a pressure cap 150, and a flow guiding assembly 160. The sensor is clamped and fixed between the mounting box 130 and the pressure cap 150 through the cooperation of the first mounting port 132 and the second mounting port 152, simplifying the installation process and facilitating subsequent disassembly.

[0032] The sensor and the oil tank 120 are placed in separate installation boxes 130 and oil tank 120 spaces, and the detection medium is connected through the flow guide assembly 160. This avoids the sensor from being directly immersed in the oil, which could lead to contamination or mechanical damage, and also makes it easy to repair the sensor separately without affecting the sealing of the oil tank 120.

[0033] The clamping structure of the pressure cap 150 and the mounting box 130 forms a uniform circumferential clamping force on the sensor. Compared with screw fixing, it can effectively reduce the risk of loosening caused by vibration, while improving the sealing reliability of the sensor interface and the flow guide assembly 160 and preventing oil leakage.

[0034] The flow guiding component 160 serves as a directional transmission channel between the sensor and the oil tank 120, which can optimize the flow path of the oil sample, ensure the representativeness of the test data, and reduce cross-contamination of oil residues to subsequent tests.

[0035] The oil moisture detector 100 provided in this application allows the sensor to be removed simply by disconnecting the connection between the pressure cap 150 and the mounting box 130 when the sensor needs to be repaired or replaced. This does not require opening the oil tank 120, thereby improving the maintenance efficiency of the equipment, significantly simplifying the replacement process of faulty sensors, and reducing maintenance time and labor costs.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, optionally, the pressure cap 150 includes: a fixing cap 154, the fixing cap 154 ​​having a first mounting notch on the side facing the sensor; a fixing plate 156, disposed on one side of the fixing cap 154, the fixing plate 156 having a second mounting notch on the side facing the sensor, the first mounting notch and the second mounting notch combining to form a second assembly port 152; and a pressure plate 158, disposed on the other side of the fixing cap 154, the pressure plate 158 having a third mounting notch on the side facing the flow guide assembly 160.

[0037] In this embodiment, the pressure cap 150 includes a fixing cap 154, a fixing plate 156, and a pressure plate 158. The fixing cap 154 ​​and the fixing plate 156 are respectively provided with a first mounting notch and a second mounting notch. The combined design of the two mounting notches forms an adjustable second mounting opening 152, which can accommodate the mounting and fixing requirements of sensors of different sizes. A third mounting notch on the pressure plate 158 can limit and fix the flow guiding assembly 160.

[0038] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, the number of sensors is multiple, including at least one of oil water content sensor 140, oil viscosity sensor 142 and oil density sensor 146.

[0039] In this embodiment, there are multiple sensors. Correspondingly, the first mounting port 132 and the second mounting port 152 include multiple corresponding mounting notches, which are arranged side by side, and each mounting notch is used to install one type of sensor. By integrating multiple sensors such as water content, viscosity, and density, multiple key indicators of the oil can be detected simultaneously, improving detection efficiency, avoiding the accumulation of errors from step-by-step measurements, and ensuring data consistency and accuracy.

[0040] The sensor is connected to the oil tank 120 via the flow guide assembly 160, avoiding direct immersion in the oil. This reduces the impact of oil contamination on the sensor and prevents signal interference between different sensors, thus improving detection accuracy. Multiple sensors are centrally arranged on the mounting box 130 and fixed via the first assembly port 132 and the second assembly port 152, making the overall structure more compact, reducing the size of the detector, and facilitating standardized production and assembly.

[0041] like Figure 1 and Figure 3As shown, in some embodiments, optionally, the flow guiding assembly 160 includes: a liquid extraction pipe 162, one end of which is connected to a sensor, and the other end of which is connected to an oil storage tank 120, and the liquid extraction pipe 162 is disposed on the outside of the mounting box 130; and a liquid discharge pipe 166, one end of which is connected to a sensor, and the other end of which is connected to an oil storage tank 120, and the liquid discharge pipe 166 is disposed on the outside of the mounting box 130.

[0042] In this embodiment, the flow guiding assembly 160 includes a suction pipe 162 and a discharge pipe 166. The suction pipe 162 is responsible for directionally transporting the oil to be tested in the oil storage tank 120 to the sensor, and the discharge pipe 166 guides the tested oil back to the oil storage tank 120, forming a closed-loop flow, avoiding oil stagnation or contamination of the sensor, and improving the continuity and reliability of the detection results.

[0043] Both the suction pipe 162 and the drain pipe 166 are located on the outside of the mounting box 130, making the pipe connection points visible and tangible, facilitating the inspection of blockages or leaks, and enabling quick cleaning or replacement of the pipes, thus reducing maintenance difficulty.

[0044] To avoid occupying internal space of the mounting box 130, the sensors are arranged more compactly; the external pipeline facilitates oil flow and heat dissipation, preventing long-term contact of high-temperature oil with the sensors from affecting measurement accuracy.

[0045] like Figure 3 As shown, in some embodiments, the oil moisture detector 100 may optionally include: a pump 164 disposed in the pumping pipe 162; and a pump disposed in the draining pipe 166.

[0046] In this embodiment, the oil moisture detector 100 also includes a pump 164 and a pump 164. The pump 164 draws oil from the oil storage tank 120 and delivers it to the sensor. The pump 164 returns the detected oil to the oil storage tank 120, forming a closed-loop flow system to prevent oil stagnation or deposition from affecting the subsequent detection accuracy of the sensor.

[0047] By adjusting the power of the pump 164 and the discharge pump, the oil flow rate can be controlled as needed to adapt to the detection requirements of different sensors. For high-viscosity or impurity-containing oils, pumping can overcome flow resistance, ensuring that the oil continuously passes through the sensor and expanding the range of applicable oils for the detector.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the oil moisture detector 100 further includes: an inlet pipe 170 disposed on the body 110 and connected to the oil storage tank 120; and an outlet pipe 172 disposed on the body 110 and connected to the oil storage tank 120.

[0049] In this embodiment, the oil moisture analyzer 100 further includes an inlet pipe 170 and an outlet pipe 172. The inlet pipe 170 is used to input external oil into the oil storage tank 120, allowing for the replenishment of the oil sample to be tested without opening the tank, thus improving testing efficiency. The outlet pipe 172 is used for the rapid discharge or replacement of oil after testing, avoiding the risk of contamination from manual oil pouring and simplifying the operation process. By continuously injecting different oil samples through the inlet pipe 170, automated multi-batch testing of oil can be achieved.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the oil moisture detector 100 may optionally include: an inlet pump 174 disposed in the inlet pipe 170; and an outlet pump 176 disposed in the outlet pipe 172.

[0051] In this embodiment, the oil moisture analyzer 100 further includes an inlet pump 174 and an outlet pump 176. The inlet pump 174 controls the injection flow rate and speed of the oil to be tested, injecting the oil to be tested into the oil storage tank 120 through the inlet pipe 170. The outlet pump 176 discharges the tested oil or waste liquid, working in conjunction with the inlet pump 174 to achieve a fully automated liquid replacement process, completely eliminating manual operation.

[0052] like Figure 1 As shown, in some embodiments, optionally, the mounting box 130 is provided with ear plates 180 on both sides, and the cover 150 is provided with clamping plates 182 corresponding to the ear plates 180 on both sides, and the ear plates 180 and clamping plates 182 are connected by bolts.

[0053] In this embodiment, the mounting box 130 and the cover 150 are fixed by bolting the ear plate 180 and the clamping plate 182. By adopting the corresponding structure of the ear plate 180 and the clamping plate 182, there is no need to reposition during replacement. When disassembling the sensor, simply loosen the bolts to separate the cover 150 from the mounting box 130. Compared with the traditional screw fixing method, this saves sensor replacement time.

[0054] like Figure 5 and Figure 6 As shown, in some embodiments, the oil moisture detector 100 may optionally include a cover plate 190, which is detachably disposed on the body 110, and the cover plate 190 is used to open or close the cavity.

[0055] In this embodiment, the oil moisture detector 100 also includes a cover plate 190. The cover plate 190 is detachably connected to the main body 110. When the cover plate 190 is closed, it can prevent external dust / liquids from entering the contents of the main body 110. When the cover plate 190 is open, it can enable immediate maintenance of core components such as sensors and flow guiding components 160.

[0056] like Figure 1 and Figure 6 As shown, in some embodiments, the oil moisture detector 100 may optionally include: a locking block 192 disposed on one side of the body 110; and a locking plate 194 disposed on the cover plate 190, wherein the locking plate 194 can be locked inside the locking block 192 to restrict the movement of the cover plate 190 relative to the body 110.

[0057] In this embodiment, the oil moisture detector 100 further includes a locking plate 194 and a locking block 192. The locking plate 194 and the locking block 192 are respectively disposed on the cover plate 190 and the body 110. Through the locking engagement of the locking block 192 and the locking plate 194, the cover plate 190 can be quickly aligned and locked in place, and the opening and closing operation can be completed without tools, ensuring that the cover plate 190 and the body 110 fit tightly together and preventing loosening or displacement caused by vibration.

[0058] like Figure 5 As shown, in some embodiments, optionally, the oil moisture detector 100 further includes: an operation panel 200 disposed on the body 110, the operation panel 200 being used to control the sensor; and a display screen 210 disposed on the body 110, spaced apart from the operation panel 200, the display screen 210 being used to display the sensor's detection information.

[0059] In this embodiment, the oil moisture detector 100 also includes an operation panel 200 and a display screen 210. The spacing between the operation panel 200 and the display screen 210 forms the human-machine interface of the oil moisture detector 100. Users can directly control the sensor start / stop, mode switching, and other functions through the operation panel 200, and view the detection data in real time, realizing integrated operation of "detection-control-display".

[0060] The operation panel 200 has a built-in control module that allows programmable settings for detection parameters (such as sampling frequency and alarm threshold), while the display screen 210 provides synchronous feedback on the dynamic changes of key indicators such as oil water content, upgrading the detection process from manual operation to a configurable automated process.

[0061] In addition to displaying routine test data, the display screen 210 can also indicate the sensor status (such as calibration reminders and fault alarms) through color coding or icons. Combined with the debugging buttons on the panel, it can quickly locate the cause of abnormalities and greatly improve maintenance efficiency.

[0062] In specific embodiments, such as Figures 1 to 6As shown, this application provides an oil moisture detector 100, including a detector body, an operation panel 200 on the front side of the detector body, a rear cover plate on the rear side of the detector body, four sets of clamping plates 194 on the front side of the rear cover plate, all four sets of clamping plates 194 are clamped and installed inside the clamping blocks 192, all four sets of clamping blocks 192 are set on the left and right inner walls of the detector body, and the rear cover plate is fixedly installed on the rear side of the detector body by four sets of bolts. The detector body has an internal oil storage tank 120. The top of the oil storage tank 120 is connected to the inlet pipe 170 via an inlet pump 174, and the bottom of the oil storage tank 120 is connected to the outlet pipe 172 via an outlet pump 176. The oil storage tank 120 is located on the front inner wall of the detector body. The top of the detector body has an installation box 130. The left and right sides of the installation box 130 are provided with ear plates 180, and clamping plates 182 are provided at the positions corresponding to the two sets of ear plates 180. The two sets of ear plates 180 and clamping plates 182 are fixedly connected by bolts.

[0063] In this design, the operation panel 200 and display screen 210 are located on the front of the detector body for easy operation and data viewing. The rear cover is secured to the detector body via four sets of locking plates 194 and locking blocks 192, as well as bolts, ensuring a stable connection and improving overall sealing and durability. The oil tank 120 smoothly introduces oil through a first liquid pump and an inlet pipe 170, and discharges oil through a second liquid pump and an outlet pipe 172, ensuring oil recycling during the testing process. The oil tank 120 is located on the front of the detector body for easy connection with subsequent detection sensors via liquid circuits.

[0064] The mounting box 130 is equipped with an oil moisture content sensor 140, an oil viscosity sensor 142, and an oil density sensor 146. The outer surfaces of the oil moisture content sensor 140, oil viscosity sensor 142, and oil density sensor 146 are fitted with mounting notches on the fixing cover 154 and the fixing plate 156. The top of the fixing cover 154 is provided with a pressure plate 158 corresponding to the oil moisture content sensor 140, oil viscosity sensor 142, and oil density sensor 146. The outer surfaces of the oil moisture content sensor 140, oil viscosity sensor 142, and oil density sensor 146 are all connected to the bottom of the oil storage tank 120 through the liquid extraction pipe 162 and the liquid extraction pump 164. The rear side of the oil storage tank 120 is connected to the top of the oil moisture content sensor 140, oil viscosity sensor 142, and oil density sensor 146 through the liquid drain pipe 166. The liquid extraction pipe 162 and the liquid drain pipe 166 are interconnected with the oil storage tank 120.

[0065] In this design, the mounting box 130 serves as a supporting structure. The lugs 180 and clamping plate 182 are bolted together, ensuring stable installation of multiple sensors. A closed-loop liquid path is formed between the liquid extraction pipe 162 and the third liquid pump, connecting to the oil storage tank 120. This ensures that the oil sample flows uniformly and continuously through each sensor, enabling comprehensive detection of various oil properties. Furthermore, the design of the fixing cover 154 and fixing plate 156 on the sensor's outer surface, along with the reinforcement of the pressure plate 158, further enhances the sensor's stability, preventing shaking or displacement during detection and ensuring the accuracy of the detection data.

[0066] The working principle of this application is as follows: First, the user operates the instrument via the control panel 200 on the front side of the instrument body to start the instrument and prepare for oil testing. A rear cover plate is provided on the rear side of the instrument body. The rear cover plate is secured to the instrument body by a snap-fit ​​structure of four sets of clamping plates 194 and clamping blocks 192, as well as additional bolts, ensuring a stable connection between the rear cover plate and the instrument body, thereby guaranteeing the instrument's sealing and durability. When an oil sample needs to be introduced, the inlet pump 174 starts, introducing the oil sample into the oil storage tank 120 through the inlet pipe 170. The bottom of the oil storage tank 120 is connected to the outlet pipe 172 via the outlet pump 176, used to discharge the oil after testing, ensuring the recycling of the oil during the testing process. The oil reservoir 120 is located at the front of the detector body for easy liquid circuit connection with subsequent detection sensors. The mounting box 130 houses the oil water content sensor 140, oil viscosity sensor 142, and oil density sensor 146. The outer surfaces of these sensors fit snugly against the mounting notches on the fixing cover 154 and fixing plate 156, and are further reinforced by the pressure plate 158 to ensure sensor stability during detection. During detection, the oil sample in the reservoir 120 is evenly drawn and transported to each sensor via the extraction pipe 162 and the extraction pump 164. The sensors detect properties such as water content, viscosity, and density of the oil. After detection, the oil flows back to the reservoir 120 through the drain pipe 166, ensuring a continuous and even flow of the oil sample through each sensor, thereby improving the accuracy and reliability of the detection.
