Description

Technical Field

[0001] This invention provides an online cleaning device for an insertion probe, belonging to the field of online monitoring technology. Background Technology

[0002] With the continuous improvement of industrial automation and intelligence, the insertion sensors deployed in modern production systems are showing a trend of high density and precision. However, in complex working conditions, the measurement accuracy of sensor probes is easily affected by contamination problems such as media adhesion and scaling. Especially for pressurized operating conditions, traditional maintenance methods require cleaning operations such as system shutdown, pressure release, and equipment disassembly. This not only causes direct economic losses due to production interruption, but also restricts the continuous operation requirements of industrial processes.

[0003] Based on this, Chinese invention patent (CN102980982A) proposes a water quality sensing device with an automatic cleaning function. This device mounts a cleaning structure onto the sensing device via a vertical support. The cleaning structure includes a cleaning roller with flexible cleaning materials such as cloth, cotton, or a brush on it. As the cleaning roller rotates, its surface wipes and cleans the sensing probe. To extend the lifespan of the cleaning materials, the cleaning structure is installed above the water surface. When cleaning the sensing device is needed, a motor drives a drive rod to lift the probe out of the water. The sensing drive structure then rotates around a rotating axis, moving the probe to the cleaning structure for wiping and cleaning. However, the aforementioned water quality sensing device with an automatic cleaning function has a complex structure, a cumbersome cleaning process, and cannot provide continuous monitoring during the cleaning process.

[0006] The outer wall of the second fixing device is fixedly connected to the monitoring platform, and the inner wall of the second fixing device is connected to a cleaning component through a fixing member. The cleaning component cooperates with the probe fixed on the first fixing device.

[0007] Furthermore, a groove is provided on the end face of the first fixing device connected to the movable part, and a sealing element is provided in the groove, the sealing element cooperating with the movable part.

[0008] Furthermore, the structure of the inner wall of the movable component is adapted to the structure of the probe, and the structure of the inner wall of the second fixing device is adapted to the structure of the probe.

[0009] Furthermore, the cleaning component employs a flexible scraper.

[0010] Furthermore, the movable part and the second fixing device are connected as one unit by the first nut.

[0011] Furthermore, the first fixing device is a flange, and the movable part is fixed to the first fixing device by bolts and a second nut.

[0012] Furthermore, the sealing element is a rubber sealing ring.

[0013] The advantages of this utility model over the prior art are as follows:

[0014] 1. The movable part, the second fixing device and the cleaning part of this utility model cooperate with each other to realize the cleaning of the probe. Moreover, during the cleaning process, it is not necessary to remove the probe from the monitored medium to realize online monitoring, thus avoiding the loss caused by downtime cleaning and having economic value.

[0015] 2. The present invention has a simple structure and a simple cleaning process. The purpose of online cleaning of the probe can be achieved simply by rotating the movable part. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0018] In the diagram: 1 is the movable part, 2 is the first fixing device, 3 is the second fixing device, 4 is the fixing part, 5 is the cleaning part, 6 is the probe, 7 is the sealing part, 8 is the first nut, 9 is the bolt, and 10 is the second nut. Detailed Implementation

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate relative orientations or positional relationships and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown, this utility model provides an online cleaning device for an insertion probe, including a hollow movable component 1, which is a columnar structure. One end of the movable component 1 is fixedly connected to a first fixing device 2, specifically, the first fixing device 2 is a flange, and the movable component 1 is fixed to the first fixing device 2 by bolts 9 and a second nut 10. The other end of the movable component 1 is movably connected to a hollow second fixing device 3, which is coaxially arranged with the movable component 1 and connected to the movable component 1 by a first nut 8. The movable component 1 and the second fixing device 3 can rotate relative to each other.

[0022] The end face of the second fixing device 3 connected to the movable part 1 has a groove, and a sealing element 7 is placed in the groove. The sealing element 7 is a rubber sealing ring. The sealing element 7 and the movable part 1 cooperate with each other to achieve the purpose of sealing.

[0023] The outer wall of the second fixing device 3 is welded to the monitoring platform. The inner wall of the second fixing device 3 is connected to the cleaning component 5 through the fixing component 4. The cleaning component 5 is a flexible scraper. The cleaning component 5 cooperates with the probe 6 fixed on the first fixing device 2. Specifically, the structure of the inner wall of the movable component 1 is adapted to the structure of the probe 6, the structure of the inner wall of the second fixing device 3 is adapted to the structure of the probe 6, and the end face of the cleaning component 5 that fits with the probe 6 is adapted to the probe 6. During the process of the movable component 1 driving the probe 6 to rotate, the probe 6 and the cleaning component 5 are in contact. The cleaning component 5 rotates relative to the outer wall of the probe 6, thereby achieving the purpose of online cleaning of the probe 6. Compared with the traditional device for cleaning the probe 6, it is not necessary to remove the probe 6 from the monitoring medium to clean the probe 6. That is, while cleaning the probe 6, it does not affect the real-time monitoring of the environment by the probe 6, and the monitoring and cleaning are carried out simultaneously.

[0024] The working principle of this utility model is as follows:

[0025] The online cleaning device for the insertion probe of this utility model achieves the insertion of the probe 6 into the medium to be monitored by fixing the second fixing device 3 to the monitoring platform. When the probe 6 needs to be cleaned, the external force is applied to the movable part 1 through the first fixing device 2, causing the movable part 1 to rotate. The movable part 1 drives the probe 6 to rotate. Since the probe 6 and the cleaning part 5 are in close contact with each other, the cleaning part 5 can rotate relative to the outer side wall of the probe 6 when the probe 6 rotates, so that the cleaning part 5 can clean the adhering substances on the surface of the probe 6, thereby achieving the purpose of cleaning the probe 6.
