Description

Technical Field

[0001] The utility model relates to the technical field of rod-shaped sensor cleaning, in particular to a rod-shaped sensor cleaning device. Background Art

[0002] Sensors are the basis of automated monitoring and are widely used in various industries. Many sensors need to be tested by contacting the substance to be detected. In order to increase the contact surface size, many sensors are designed as flat rods or round rods. Since many substances to be detected are sticky, during the detection process, the substance to be detected may remain at the detection position of the sensor, and long-term accumulation will lead to a decrease in the detection accuracy of the sensor.

[0003] In response to this problem, some sensor cleaning devices have been developed on the market. For example, Chinese patent CN220028023U discloses a material level sensor cleaning device, which cleans the dust on the sensor surface through an external air source, but it is difficult to completely clean the sticky substances on the sensor surface only by blowing the gas. Chinese patent CN116197154B discloses a sand and gravel moisture content detector sensor cleaning device, which completes the sensor cleaning through a cleaning ring that is tightly attached to the side wall of the sensor, but its structure is relatively complex, difficult to install and disassemble, and has strong limitations in use.

[0004] Therefore, on the basis of not moving or moving the rod-shaped sensor as little as possible, there is an urgent need for a rod-shaped sensor cleaning device with a simple structure, strong adaptability, good cleaning effect for different detected substances, and easy installation and disassembly.

[0007] Furthermore, the driving device is fixed on the rod-shaped sensor through a clamp, and the nozzle is fixed on the top of the driving device through a clamp.

[0008] Furthermore, the driving device is a cylinder push rod, an electric push rod or a hydraulic push rod.

[0009] Furthermore, the cleaning plate is a brush, a hard baffle, or a combination of a brush and a hard baffle.

[0011] Furthermore, the driving device is connected to a host computer.

[0012] Furthermore, the air pipe is provided with a solenoid valve, and the solenoid valve is connected to a host computer.

[0013] Compared with the existing technology, the beneficial effects of the utility model are:

[0014] 1. The utility model uses a cleaning plate to clean the detected object on the rod-shaped sensor from the sensor surface, and then sprays gas through the nozzle to clean the residual detected substance. The structure is simple and easy to install and use.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] The utility model provides a cleaning device for cleaning the detected substance on the surface of a rod-shaped sensor, such as Figure 1As shown, the rod-shaped sensor cleaning device includes a cleaning plate 2, a driving device 3 and a nozzle 4. The cleaning plate 2 is fixedly connected to the driving device 3. Generally, the detected substance will only adhere to a part of the rod-shaped sensor. Therefore, the driving device 3 is installed on the side where the attachment of the rod-shaped sensor 1 is located, and is used to drive the cleaning plate 2 to reciprocate along the axial direction of the rod-shaped sensor 1. In this embodiment, the rod-shaped sensor is a flat rod, the surface of the attachment part is a plane, and the cleaning plate 2 is a flat plate. The cleaning plate 2 can also be an arc plate, which is used for cleaning the surface of the attachment part of the round rod-shaped sensor. The nozzle 4 is installed on the top of the driving device 3, and the nozzle 4 is connected to the air compressor 6 through the air pipe 5.

[0023] In this embodiment, the cleaning plate 2 is a hard baffle, and may also be a brush or a combination of a brush and a hard baffle. The driving device 3 is a cylinder push rod, an electric push rod or a hydraulic push rod, and the push rod of the driving device 3 extends in a direction parallel to the axial direction of the rod-shaped sensor 1. The nozzle 4 is tilted downward and faces the attachment part of the rod-shaped sensor 1, and the angle between the nozzle 4 and the surface of the attachment part of the rod-shaped sensor 1 is 10°-60°.

[0024] When connecting with the rod-shaped sensor 1, in order not to make changes to the structure of the rod-shaped sensor 1 itself, as an improvement, the present embodiment uses a clamp to fix the nozzle 4 to the power source of the driving device 3, and then uses a clamp to fix the power source of the driving device 3 to the rod-shaped sensor 1. The driving device 3 drives the cleaning plate 2 to move back and forth to clean the detected substance on the surface of the rod-shaped sensor 1, and then sprays gas through the nozzle 4 to thoroughly clean the detected substance remaining on the surface of the rod-shaped sensor 1.

[0025] As a further improvement, the driving device 3 is connected to the host computer, the air pipe 6 is provided with a solenoid valve, and the solenoid valve is connected to the host computer. After the host computer reads that the rod-shaped sensor 1 has been working for a certain period of time, it controls the driving device 3 to drive the cleaning plate 2 for cleaning, and then controls the solenoid valve to open, allowing the nozzle 4 to spray for cleaning.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
