Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring sensor technology, and in particular to a telescopic detection probe structure for a smart water hardness sensor. Background Technology

[0002] Water hardness is a key indicator of water quality, primarily determined by the concentration of calcium and magnesium ions in the water, and has a significant impact on industrial boilers, agricultural irrigation, aquaculture, and daily water use. Online water hardness sensors monitor water hardness in real time through contact between their probes and the water. However, existing fixed-installation probes have significant drawbacks in practical applications: long-term immersion in water makes them susceptible to contamination by algae, microbial films, scale, and other pollutants, leading to passivation of the detection membrane surface, decreased response sensitivity, and distorted measurement data. This necessitates frequent manual cleaning and maintenance, affecting the continuity and accuracy of monitoring. Furthermore, during sensor calibration, maintenance, or long-term shutdown, the probe cannot be retracted for protection, leaving it exposed to complex aquatic environments, accelerating corrosion and aging, and shortening its lifespan. Therefore, those skilled in the art provide a retractable detection probe structure for a smart water hardness sensor to address the problems mentioned in the background. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a telescopic detection probe structure for a smart water hardness sensor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A telescopic detection probe structure for a smart water hardness sensor includes a sensor body, a mounting frame fixedly installed at the detection end of the sensor body, a positioning frame fixedly installed on one side inside the mounting frame, an adjustment component fixedly installed on the surface of the positioning frame, a probe threadedly connected to the inside of the adjustment component, a cleaning component fixedly installed inside the mounting frame, a mounting ring fixedly installed at the edge inside the mounting frame, a guide ring fixedly installed inside the mounting ring, and a probe penetrating through the inside of the guide ring.

[0005] As a further embodiment of this utility model, the adjustment component includes a servo motor fixedly installed at the bottom of the positioning frame, a meshing wheel fixedly installed at the output end of the servo motor, a threaded cylinder meshing with the surface of the meshing wheel, and a probe connected to the internal thread of the threaded cylinder.

[0006] As a further embodiment of this utility model, the surface of the threaded cylinder is provided with an adjustment groove, the size of which is adapted to the size of the meshing wheel, and meshing stripes are provided inside the adjustment groove and on the surface of the meshing wheel.

[0007] As a further embodiment of this invention, the probe has a threaded groove on its surface, the size of which is adapted to the size of the inside of the threaded cylinder.

[0008] As a further embodiment of this utility model, the cleaning component includes a positioning ring fixedly installed inside the mounting frame, telescopic rods fixedly installed on both sides inside the positioning ring, a spring sleeved on the surface of the telescopic rods, and an arc-shaped plate fixedly installed at one end of the telescopic rods.

[0009] As a further embodiment of this utility model, the surface of the arc-shaped plate is provided with an embedding groove, and a cleaning sponge pad to improve cleaning efficiency is embedded inside the embedding groove.

[0010] As a further embodiment of this utility model, mounting grooves are provided on both sides of the surface of the positioning frame, and positioning bolts for positioning and installation are provided inside the mounting grooves.

[0011] As a further improvement of this invention, one end of the probe is provided with a power cord, and one end of the power cord is connected to the input end of the sensor body.

[0012] The beneficial effects of this utility model are as follows: 1. A servo motor drives a meshing wheel that engages with a threaded cylinder, causing the probe to extend or retract precisely under the guidance of a guide ring. During non-detection periods, the probe can be completely retracted into the mounting frame, avoiding prolonged immersion in water, significantly reducing contaminant adhesion and equipment corrosion, and extending the probe's service life.

[0013] 2. During retraction, the probe automatically passes through a cleaning channel formed by the cleaning assembly. The curved plates on both sides, spring-loaded, continuously clamp the probe surface, while the cleaning sponge pads effectively wipe away dirt and water stains, keeping the detection window clean. This ensures the accuracy and stability of the measurement data and significantly reduces the frequency of manual cleaning and maintenance costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0017] Reference Figures 1-4 A telescopic detection probe structure for a smart water hardness sensor includes a sensor body 1. A mounting frame 2 is fixedly installed at the detection end of the sensor body 1. A positioning frame 3 is fixedly installed on one side inside the mounting frame 2. Mounting grooves are provided on both sides of the surface of the positioning frame 3. Positioning bolts for positioning are provided inside the mounting grooves. An adjustment component 4 is fixedly installed on the surface of the positioning frame 3. A probe 5 is threadedly connected inside the adjustment component 4. A power cord is provided at one end of the probe 5. One end of the power cord is connected to the input end of the sensor body 1. A cleaning component 6 is fixedly installed inside the mounting frame 2. A mounting ring 7 is fixedly installed at the edge inside the mounting frame 2. A guide ring 8 is fixedly installed inside the mounting ring 7. The probe 5 passes through the inside of the guide ring 8.

[0018] In this utility model, the adjustment component 4 includes a servo motor 41 fixedly installed at the bottom of the positioning frame 3. A meshing wheel 42 is fixedly installed at the output end of the servo motor 41. A threaded cylinder 43 meshes with the surface of the meshing wheel 42. A probe 5 is threadedly connected inside the threaded cylinder 43. An adjustment groove is provided on the surface of the threaded cylinder 43. The size of the adjustment groove is adapted to the size of the meshing wheel 42. Meshing stripes are provided inside the adjustment groove and on the surface of the meshing wheel 42. A threaded groove is provided on the surface of the probe 5. The size of the threaded groove is adapted to the size inside the threaded cylinder 43.

[0019] In particular, when water hardness testing is required, the sensor control system starts the servo motor 41. The output of the servo motor 41 drives the meshing wheel 42 to rotate. The meshing wheel 42 drives the threaded cylinder 43 to rotate through the meshing stripes. When the threaded cylinder 43 rotates, it will drive the probe 5 to extend and retract outward inside the sensor body 1, thereby improving the efficiency of rapid extension and retraction and response of the probe 5.

[0020] In this utility model, the cleaning component 6 includes a positioning ring 61 fixedly installed inside the mounting frame 2. Telescopic rods 62 are fixedly installed on both sides inside the positioning ring 61. A spring 63 is sleeved on the surface of the telescopic rod 62. An arc plate 64 is fixedly installed on one end of the telescopic rod 62. An embedding groove is opened on the surface of the arc plate 64. A cleaning sponge pad to improve cleaning efficiency is embedded inside the embedding groove.

[0021] In particular, when the probe 5 completes its detection and extends inward, the probe 5 will squeeze the arc plate 64 to both sides. After the arc plate 64 is squeezed, it will squeeze the spring 63 through the telescopic rod 62. After the spring 63 is squeezed, it will drive the arc plate 64 to move towards the center through the telescopic rod 62. The cleaning sponge pad on the surface of the arc plate 64 will clean and scrape the foreign objects on the surface of the probe 5.

[0022] Working principle: First, when water hardness testing is required, the sensor control system starts the servo motor 41. The output end of the servo motor 41 drives the meshing wheel 42 to rotate. The meshing wheel 42 drives the threaded cylinder 43 to rotate through the meshing stripes. When the threaded cylinder 43 rotates, it will drive the probe 5 to extend and retract outward inside the sensor body 1. After the probe 5 completes the test, when it extends and retracts inward, the probe 5 will squeeze the arc plate 64 to both sides. After the arc plate 64 is squeezed, it will squeeze the spring 63 through the telescopic rod 62. After the spring 63 is squeezed, it will drive the arc plate 64 to move towards the middle through the telescopic rod 62. The cleaning sponge pad on the surface of the arc plate 64 will clean and scrape away foreign objects on the surface of the probe 5.
