Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to an inductive water quality sensor. Background Technology

[0002] An inductive water quality sensor is a non-contact conductivity detection device based on the principle of electromagnetic induction. When in use, water flows through the induction coil. Because the conductivity of the water body is different, the induced current is different, and the water quality can be analyzed based on the conductivity of the water body.

[0003] When using an inductive water quality sensor, the internal inductive element is sealed at the bottom of the housing. Non-contact detection is performed by inserting the bottom of the housing into the water. However, during long-term monitoring, microorganisms and impurities in the water will adhere to the surface of the housing, which will affect the conductivity measurement and cause errors in water quality detection. Therefore, an inductive water quality sensor is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an inductive water quality sensor that solves the problem that microorganisms and impurities in the water can adhere to the surface of the housing during long-term monitoring, thus affecting the conductivity measurement and causing errors in water quality detection.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an inductive water quality sensor, comprising a sealed housing and an inductive element installed inside the bottom end of the sealed housing, wherein an end cleaning unit is provided outside the sealed housing, and the end cleaning unit includes;

[0006] A sliding tube, which is slidably disposed on the outer wall of the top end of the sealed housing;

[0007] A rotating component, the rotation of which is located at the bottom end of the sliding tube;

[0008] A cleaning component is fixedly installed on the inner side of the bottom end of the rotating component;

[0009] An externally threaded tube is fixedly disposed on the outer wall of the sealing housing and is threadedly engaged with the rotating component;

[0010] When the sliding tube pushes the rotating component up and down, the external threaded tube causes the cleaning component to move spirally to clean the outer wall of the bottom end of the sealing housing.

[0011] Preferably, an electric telescopic cylinder is fixedly installed on the inner top of the sealed housing, and the output end of the electric telescopic cylinder is fixedly connected to the sliding tube.

[0012] Preferably, a support sleeve is provided at the top of the sealing housing, and the sliding tube is slidably disposed on the inner wall of the support sleeve.

[0013] Preferably, a fixing block is fixedly connected between the inner bottom sides of the support sleeve and the sealing shell, and a sliding groove is provided on both sides of the sliding tube, through which the fixing block passes.

[0014] Preferably, a wire is installed in the side wall of the support sleeve, and the wire extends into the interior of the sealed housing.

[0015] Preferably, the inner wall of the rotating component is provided with a threaded groove that is compatible with the external threaded pipe.

[0016] Preferably, the cleaning component includes a hollow tube integrally formed at the bottom end of the rotating component, the bottom end of the hollow tube is tapered inward to fit against the outer wall of the sealing housing, and the inner wall of the hollow tube is provided with brush heads and sponge wipes at intervals.

[0017] This utility model discloses an inductive water quality sensor, which has the following beneficial effects: By installing a timer switch to control the electric telescopic cylinder, the output end of the electric telescopic cylinder retracts at regular intervals. When the output end of the electric telescopic cylinder retracts, it drives the sliding tube to slide downwards. At this time, the sliding tube pushes the rotating component downwards. The rotating component, through the threaded groove on its inner wall, cooperates with the external threaded tube, causing the rotating component to rotate as it slides down. This causes the brush head and sponge to spiral downwards. By controlling the repeated extension and retraction of the electric telescopic cylinder, the outer wall of the bottom of the sealed housing is cleaned, preventing impurities and microorganisms in the water from affecting the accuracy of the monitoring data during long-term monitoring. Simultaneously, after cleaning, the output end of the electric telescopic cylinder extends, causing the brush head and sponge to detach from the water, preventing impurities and microorganisms from adhering to the brush head and sponge.

When the sliding tube 21 pushes the rotating component 22 to move up and down, the cleaning component 23 moves spirally through the externally threaded tube 24 to clean the outer wall of the bottom end of the sealed housing 1.

[0028] An electric telescopic cylinder 25 is fixedly installed on the inner top of the sealed housing 1. The output end of the electric telescopic cylinder 25 is fixedly connected to the sliding tube 21. A support sleeve 13 is provided at the top of the sealed housing 1. The sliding tube 21 is slidably disposed on the inner wall of the support sleeve 13. Fixing blocks 15 are fixedly connected between the inner bottom sides of the support sleeve 13 and the sealed housing 1. Sliding grooves 26 are provided on both sides of the sliding tube 21. The fixing blocks 15 pass through the sliding grooves 26. The output end of the electric telescopic cylinder 25 retracts at regular intervals. When the output end of the electric telescopic cylinder 25 retracts, it drives the sliding tube 21 to slide downward. At this time, the sliding tube 21 pushes the rotating part 22 to move downward.

[0029] A wire 14 is installed in the side wall of the support sleeve 13. The wire 14 extends into the interior of the sealed housing 1. A signal processing circuit board is also installed inside the sealed housing 1. The signal processing circuit board processes the information collected by the inductive element 12 and connects the wire 14 to the external control box for collecting and remotely transmitting the water quality data collected by the entire inductive water quality sensor.

[0030] The inner wall of the rotating part 22 is provided with a threaded groove 27 that is compatible with the external threaded tube 24.

[0031] The cleaning component 23 includes a hollow tube 231 integrally formed at the bottom end of the rotating component 22. The bottom end of the hollow tube 231 is tapered inward and fits against the outer wall of the sealing housing 1. A brush head 232 and a sponge 233 are spaced apart on the inner wall of the hollow tube 231, so that the hollow tube 231 can move up and down while keeping close to the sealing housing 1, and the brush head 232 and the sponge 233 can scrape and clean the impurities on the bottom outer wall of the sealing housing 1.

[0032] Working principle: In use, the support sleeve 13 is fixed above the monitored water area, allowing the bottom end of the sealed housing 1 to be inserted into the water. Then, the wire 14 is connected to an external control box to collect and remotely transmit the water quality data acquired by the inductive water quality sensor. Simultaneously, a timer switch controls the electric telescopic cylinder 25, causing its output end to retract periodically. When the output end of the electric telescopic cylinder 25 retracts, it drives the sliding tube 21 to slide downwards. At this time, the sliding tube 21 pushes the rotating component 22 downwards. The rotating component 22, through its… The inner wall threaded groove 27 engages with the outer threaded tube 24, causing the rotating part 22 to rotate as it slides down, thereby causing the brush head 232 and sponge 233 to spiral downwards. By controlling the electric telescopic cylinder 25 to repeatedly extend and retract, the bottom outer wall of the sealed housing 1 is cleaned, preventing impurities and microorganisms in the water from affecting the accuracy of monitoring data during long-term monitoring. After cleaning, the output end of the electric telescopic cylinder 25 extends, causing the brush head 232 and sponge 233 to detach from the water, preventing impurities and microorganisms from adhering to the brush head 232 and sponge 233.
