Description

Technical Field

[0001] This utility model relates to the field of oil viscosity detection technology, specifically to a self-cleaning oil sensor for a camera condenser. Background Technology

[0002] In the fields of industrial hydraulic lubricating oil or petroleum industry, viscosity sensors are used to detect the viscosity of oil. They can reflect the changes in kinematic viscosity of oil in real time, providing an important basis for judging changes in oil quality.

[0003] When using a viscosity sensor to detect the oil in a synchronous condenser, the viscosity sensor is usually installed in the oil tank and oil pipeline of the synchronous condenser. Due to long-term use, the sensing end of the viscosity sensor may be affected by impurities in the oil, resulting in contamination or blockage of the sensing end. In order to improve the sensing accuracy of the viscosity sensor, it is necessary to backwash the viscosity sensor after use.

[0004] However, current methods for backwashing viscosity sensors typically involve blowing gas onto the sensor's sensing end surface or rinsing it with liquid. Simple blowing or rinsing can only remove surface debris, and it is not easy to remove firmly deposited substances that have been deposited on the sensor surface for a long time. This affects the cleaning effect of the sensor and makes the monitoring accuracy of the viscosity sensor inaccurate. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning oil sensor for a camera condenser. The sensor sprays oil onto the surface of a viscosity sensing sheet using a first pulse nozzle. Simultaneously, the sprayed oil drives a first scraping component to scrape away particles or dust deposited on the surface of the viscosity sensing sheet. The scraped particles or dust are then washed away by the flowing oil, making the surface of the viscosity sensing sheet clean, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning sensor for a camera condenser oil, comprising a sensor body installed on the camera condenser oil pipeline, a viscosity sensing sheet disposed on the sensor body, a protective cover fixed to the upper end of the sensor body, and the viscosity sensing sheet located inside the protective cover;

[0007] The upper inner part of the protective cover is equipped with a first scraping component for cleaning the surface of the viscosity sensor and a first pulse nozzle for rinsing the surface of the viscosity sensor. When the first pulse nozzle sprays, it provides rotational power to the first scraping component, causing the first scraping component to rotate. The first pulse nozzle is connected to the oil pipeline of the camera condenser through a liquid supply pipeline.

[0008] Preferably, the first scraping assembly includes a rotating shaft rotatably mounted inside a protective cover, with multiple connecting plates fixed at equal angles on the outer periphery of the rotating shaft, and a rubber scraper for contacting the viscosity sensing sheet fixed at one end of the connecting plate near the viscosity sensing sheet.

[0009] Preferably, the first pulse nozzle is fixed to the inner wall of the protective cover at an angle toward the viscosity sensing sheet, and the first pulse nozzle sprays toward one of the connecting plates.

[0010] Preferably, the protective cover is cylindrical, and the four sides of the protective cover are a grid formed by multiple uprights, with the first pulse nozzle located on one of the uprights.

[0011] Preferably, a temperature sensor is disposed below the viscosity sensing sheet, and a second scraping assembly for scraping the surface of the temperature sensor and a second pulse nozzle for rinsing the surface of the temperature sensor are installed at the sensor body located at the temperature sensor. The second pulse nozzle provides rotational power to the second scraping assembly when spraying, and the second pulse nozzle is connected to the liquid supply pipeline.

[0012] Preferably, the viscosity sensing sheet is connected to the upper end of the sensor body via a connecting shaft, the sensing surface of the temperature sensor is distributed in a ring around the connecting shaft, and multiple second scraping components are provided and evenly distributed on the outer periphery of the connecting shaft, with each second scraping component corresponding to a second pulse nozzle.

[0013] Preferably, the second scraping assembly includes a column rotatably mounted on the upper surface of the sensor body, with multiple support plates fixed at equal angles on the outer wall of the column, and Z-shaped rubber scrapers fixed on the side walls of the support plates, the rubber scrapers abutting against the sensing surface of the temperature sensor.

[0014] Preferably, the second pulse nozzle is obliquely fixed to the upper surface of the sensor body via a rigid tube, and the second pulse nozzle sprays oil in the direction of contact between the support plate and the temperature sensor.

[0015] Preferably, the liquid supply pipeline includes a ring pipe, which is embedded inside the sensor body. The ring pipe is connected to a second connecting pipe for connecting to the second pulse nozzle, a first connecting pipe for connecting to the first pulse nozzle, and an inlet pipe for connecting to the hydraulic pipeline of the camera adjustment device.

[0016] Preferably, one end of the inlet pipe is connected to two external connectors via a three-way pipe. One external connector is connected to the hydraulic oil line of the camera condenser, and the other external connector extends to the outside. A solenoid valve is installed on the external connector.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model utilizes the cooperation of a first pulse nozzle and a first scraping component. The first pulse nozzle is connected to the oil supply of the camera condenser via a liquid supply pipeline. When the oil supply is being transmitted through the camera condenser's oil pipeline, the first pulse nozzle sprays oil onto the surface of the viscosity sensor. Simultaneously, the sprayed oil drives the first scraping component to scrape away particles or dust deposited on the surface of the viscosity sensor. The scraped particles or dust are then flushed away by the flowing oil, keeping the surface of the viscosity sensor clean and achieving the purpose of self-cleaning the sensor, thereby improving the monitoring accuracy of the viscosity sensor.

[0037] Please see Figure 1-9 This utility model provides a technical solution: a self-cleaning sensor for a camera condenser oil, including a sensor body 1 installed on the camera condenser oil pipeline 7, a viscosity sensing sheet 2 provided on the sensor body 1, a protective cover 3 fixed to the upper end of the sensor body 1, and the viscosity sensing sheet 2 located inside the protective cover 3. The protective cover 3 can protect the viscosity sensing sheet 2, prevent damage to the viscosity sensing sheet 2 during sensor body 1 installation, and improve the service life of the sensor.

[0038] The upper inner part of the protective cover 3 is equipped with a first scraping assembly 4 for cleaning the surface of the viscosity sensor 2 and a first pulse nozzle 5 for rinsing the surface of the viscosity sensor 2. The pulse nozzle design generates stronger impact force, improving cleaning efficiency. Simultaneously, the pulsed impact method reduces damage to the sensor's sensing end, extending the sensor's lifespan. The first pulse nozzle 5 provides rotational power to the first scraping assembly 4 during spraying, causing the first scraping assembly 4 to rotate. The first pulse nozzle 5 is connected to the camera oil line 7 via a liquid supply line 6. Through the cooperation of the first pulse nozzle 5 and the first scraping assembly 4, and the first pulse nozzle 5... A pulse nozzle 5 is connected to the phase condenser oil via a liquid supply line 6. During self-cleaning, the first pulse nozzle 5 is turned on, and the oil transmitted from the phase condenser oil line 7 is sprayed onto the surface of the viscosity sensor 2 through the liquid supply line 6. At the same time, the sprayed oil pushes the connecting plate 42 of the first scraping assembly 4, so that the connecting plate 42 can rotate around the axis of the rotating shaft 41. When the connecting plate 42 rotates, it scrapes off the particles or dust deposited on the surface of the viscosity sensor 2. The scraped particles or dust are then washed by the flowing oil, so that there are no particles or dust deposits on the surface of the viscosity sensor 2, thereby achieving the purpose of self-cleaning the sensor and improving the monitoring accuracy of the viscosity sensor 2.

[0039] The first scraping assembly 4 includes a rotating shaft 41 rotatably mounted inside the protective cover 3. Multiple connecting plates 42 are fixed at equal angles on the outer periphery of the rotating shaft 41. A rubber scraper 43 for contacting the viscosity sensing sheet 2 is fixed at one end of the connecting plate 42 near the end of the viscosity sensing sheet 2. When the first pulse nozzle 5 sprays, the sprayed liquid pushes the connecting plate 42, providing rotational power to the connecting plate 42, so that the multiple connecting plates 42 rotate around the axis of the rotating shaft 41. At the same time, the connecting plate 42 drives the rubber scraper 43 to scrape and clean the surface of the viscosity sensing sheet 2 while rotating, reducing the deposition of particles or dust on the viscosity sensing sheet 2 and improving the sensing accuracy of the viscosity sensing sheet 2.

[0040] The first pulse nozzle 5 is tilted and fixed to the inner wall of the protective cover 3 in the direction of the viscosity sensing sheet 2, and the first pulse nozzle 5 sprays towards one of the connecting plates 42, which facilitates the provision of a pushing force to the edge of the connecting plate 42, so that the connecting plate 42 can rotate around the rotating shaft 41 without the need for an additional power source, thereby improving the cleaning effect on the viscosity sensing sheet 2.

[0041] The protective cover 3 is cylindrical, and its four sides are surrounded by a grid formed by multiple uprights 31. The first pulse nozzle 5 is located on one of the uprights 31. The grid structure ensures that the liquid transmitted by the camera oil pipeline 7 is not blocked and can pass through the surface of the viscosity sensor 2, so that the viscosity sensor 2 can accurately monitor the viscosity of the liquid and improve the sensor's sensing accuracy.

[0042] A temperature sensor 8 is disposed below the viscosity sensing sheet 2. A second scraping assembly 9 for scraping the surface of the temperature sensor 8 and a second pulse nozzle 10 for rinsing the surface of the temperature sensor 8 are installed at the sensor body 1 located at the temperature sensor 8. The second pulse nozzle 10 provides rotational power to the second scraping assembly 9 when spraying. The second pulse nozzle 10 is connected to the liquid supply pipeline 6. The second scraping assembly 9 scrapes the surface of the temperature sensor 8, and the second pulse nozzle 10 rinses the surface of the temperature sensor 8. The cooperation of the two improves the sensing accuracy of the temperature sensor 8.

[0043] The viscosity sensing sheet 2 is connected to the upper end of the sensor body 1 via the connecting shaft 21. The sensing surface of the temperature sensor 8 is distributed in a ring around the connecting shaft. Multiple second scraping components 9 are provided and evenly distributed around the outer periphery of the connecting shaft 21. Each second scraping component 9 corresponds to a second pulse nozzle 10. By setting multiple second scraping components 9, it is convenient to perform scraping actions on different positions of the temperature sensor 8, so as to increase the cleaning effect of the temperature sensor 8.

[0044] The second scraping assembly 9 includes a column 91 rotatably mounted on the upper surface of the sensor body 1. Multiple support plates 92 are fixed at equal angles on the outer wall of the column 91. Z-shaped rubber scrapers 93 are fixed on the side walls of the support plates 92. The rubber scrapers 93 abut against the sensing surface of the temperature sensor 8. When the second pulse nozzle 10 sprays liquid, the sprayed liquid provides a pushing force to the support plates 92, enabling the support plates 92 to rotate about the axis of the column 91. The rotation of the support plates 92 drives the rubber scrapers 93 to scrape the surface of the temperature sensor 8, thereby improving the cleanliness of the surface of the temperature sensor 8.

[0045] The second pulse nozzle 10 is obliquely fixed to the upper surface of the sensor body 1 through the rigid tube 11. The second pulse nozzle 10 sprays oil in the direction of contact between the support plate 92 and the temperature sensor 8, so that the liquid sprayed by the second pulse nozzle 10 can wash the surface of the temperature sensor 8, and at the same time use the sprayed liquid to provide rotational power for the support plate 92.

[0046] The liquid supply line 6 includes a ring pipe 61, which is embedded inside the sensor body 1. The ring pipe 61 is connected to a second connecting pipe 62 for connecting to the second pulse nozzle 10, a first connecting pipe 63 for connecting to the first pulse nozzle 5, and an inlet pipe 64 for connecting to the hydraulic line 7 of the camera adjuster. The ring pipe facilitates the supply of spray liquid to the first and second pulse nozzles, ensuring the stable operation of the self-cleaning function.

[0047] One end of the inlet pipe 64 is connected to two external connectors 65 via a three-way pipe. One external connector 65 is connected to the synchronous condenser oil line 7, and the other external connector 65 extends to the outside. A solenoid valve 66 is installed on the external connector 65. Through the three-way pipe and the solenoid valve 66, the source and flow of liquid can be flexibly controlled. When it is necessary to connect external flushing fluid, the solenoid valve 66 on the external connector 65 connected to the synchronous condenser oil line 7 is closed, and the solenoid valve 66 on the other external connector 65 is opened. External liquid is introduced into the sensor through the external connector 65 for self-cleaning, improving the flexibility of use.

[0048] The upper end of the sensor body 1 is integrally formed with an annular protrusion 12. The outer side wall of the protrusion 12 is provided with an external thread section. The oil pipe 7 of the camera condenser is provided with a thread for screwing the protrusion 12. A sealing ring 13 is provided on the side where the protrusion 12 connects to the oil pipe 7 and on the opposite side. The sealing ring 13 increases the sealing performance of the connection between the protrusion 12 and the oil pipe 7 of the camera condenser to avoid leakage.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
