Description

Technical Field

[0001] This invention relates to the field of sensor technology, and in particular to an intelligent four-electrode conductivity sensor. Background Technology

[0002] An electrode is a component in electronic or electrical devices or equipment, used as two ends for inputting or outputting current in a conductive medium (solid, gas, vacuum, or electrolyte solution); while conductivity can be called electrical conductivity. In a medium, the product of this quantity and the electric field strength E equals the conduction current density J. For isotropic media, conductivity is a scalar; for anisotropic media, conductivity is a tensor. Conductivity is a parameter used to describe the ease with which charge flows in a substance; while a sensor is a detection device that can sense the measured information and transform the sensed information into an electrical signal or other required form of information output according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording, and control.

[0003] Existing methods for comparing the conductivity of different electrodes often involve measuring the conductivity of different electrodes using different methods and then comparing the results. This process is cumbersome and inefficient. Furthermore, this method requires laboratory equipment for testing, which limits the testing location. In addition, existing electrodes are easily contaminated by impurities during conductivity testing, leading to a deterioration in their conductivity and affecting the test results, resulting in inaccurate experimental data. To address these issues, we propose an intelligent four-electrode conductivity sensor. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent four-electrode conductivity sensor that addresses the shortcomings of the prior art. This sensor enables the detection of conductivity of electrodes of different materials and sizes, greatly facilitating the comparison of conductivity values ​​of different electrodes and eliminating the cumbersome conductivity measurement process.

[0005] The technical solution of this invention to solve the above technical problems is: an intelligent four-electrode conductivity sensor, comprising a housing and relay boxes fixedly disposed at both ends of the housing, each relay box being electrically connected to a power line, a measuring chamber recessed in the upper wall of the housing, a sliding cavity disposed in the lower wall of the measuring chamber, two conductive plates tightly fitted on the lower wall of the measuring chamber, a transmission mechanism disposed between the conductive plates and the sliding cavity, conductive plates fixedly disposed on each of the two conductive plates, a conduit fixedly disposed between the sliding cavity and the relay box, a conductive wire disposed inside the conduit, a reaction mechanism disposed in the lower wall of the measuring chamber, the reaction mechanism being disposed at the center of the lower wall of the measuring chamber, a rotating rod rotatably disposed on the upper wall of the housing, a cover plate fixedly disposed on the rotating rod, the cover plate being disposed correspondingly to the measuring chamber, and a locking mechanism disposed between the end of the cover plate away from the rotating rod and the upper wall of the housing.

[0006] The technical solution further defined in this invention is:

[0007] Preferably, the transmission mechanism includes an electric slider slidably disposed in a sliding cavity, the electric slider being electrically connected to a conductive wire, a return spring being fixedly disposed on the side wall of the electric slider, the other end of the return spring being fixedly connected to the side wall of the sliding cavity, a conductive rod being fixedly disposed on the upper end of the electric slider, and the upper end of the conductive rod being fixedly connected to a conductive sheet.

[0008] Preferably, the reaction mechanism includes a vacuum chamber fixedly disposed in the lower wall of the measuring chamber, a support base fixedly disposed on the lower wall of the vacuum chamber, a rotating shaft rotatably disposed on the upper end of the support base, a highly sensitive magnetic needle fixedly disposed on the rotating shaft, a light spring fixedly disposed on each of the two side walls of the highly sensitive magnetic needle, and the other ends of the two light springs fixedly disposed on the opposite side walls of the vacuum chamber.

[0009] Preferably, the engaging mechanism includes a rubber plug fixedly disposed on the lower wall of the cover plate, with one end of the rubber plug away from the rotating rod, and the upper wall of the housing having a matching engaging cavity, with the rubber plug engaging within the engaging cavity.

[0010] Preferably, the cover plate is made of insulating material, and the cover plate and the housing are tightly fitted together.

[0011] Preferably, the rubber stopper is made of natural rubber, and the cavity and the rubber stopper are ellipsoidally shaped to match.

[0012] The beneficial effects of this invention are: through the cooperation of the measuring chamber, the electric slider, the conductive sheet and the conductive plate, we can directly put electrodes of different specifications into the measuring chamber and then conduct them. Due to the different conductivity, the magnitude of the current passing through them will be different, and the magnitude of the magnetic field generated around them will also be different. By observing and reflecting the magnitude of the magnetic field, we can compare the conductivity of different electrodes.

[0013] The present invention, through the setting of the transmission mechanism, when electrodes of different sizes are placed in, the conductive sheet and conductive plate clamp the electrodes under the action of the return spring, and can conduct the current process of the electrodes through the conductive sheet and conductive plate, so that electrodes of different sizes can be stably clamped in the measuring chamber, and at the same time, the electrodes can always be in the middle of the measuring chamber.

[0014] This invention, through the setting of the reaction mechanism, makes the current flowing through the electrodes different when a magnetic field is generated around the electrodes, resulting in different magnetic field strengths. This further causes different directional forces of the magnetic needle. With the resistance of a light spring, the conductivity of the electrodes can be determined by observing the rotation angle of the highly sensitive magnetic needle, which is very convenient and saves a lot of time and labor.

[0015] The present invention, through the setting of the locking mechanism, can isolate the measuring chamber from the outside world when the cover is placed on the measuring chamber, so as to prevent impurities from entering the measuring chamber and causing changes in the conductivity of the electrodes, and at the same time effectively prevent leakage.

[0023] Example 1

[0024] This embodiment provides an intelligent four-electrode conductivity sensor, the structure of which is as follows: Figure 1-6As shown, the device includes a housing 1 and relay boxes 2 fixedly mounted at both ends of the housing 1. Power lines 3 are electrically connected to both relay boxes 2. A measuring chamber 4 is recessed in the upper wall of the housing 1. A sliding cavity 5 is provided in the lower wall of the measuring chamber 4. Two conductive plates 6 are also tightly fitted onto the lower wall of the measuring chamber 4. A transmission mechanism is provided between the conductive plates 6 and the sliding cavity 5. Through the transmission mechanism, when electrodes of different sizes are placed in, the conductive plates 6 and conductive plates 7 clamp the electrodes under the action of the return spring 14, and the electrodes can be energized through the conductive plates 6 and conductive plates 7. This ensures that electrodes of different sizes are securely clamped in the measuring chamber 4, and that the electrodes are always positioned in the center of the measuring chamber 4. The transmission mechanism includes components that are slidably mounted within the sliding cavity 5. An electric slider 11 is electrically connected to a conductive wire 12. A return spring 14 is fixedly installed on the side wall of the electric slider 11, and the other end of the return spring 14 is fixedly connected to the side wall of the sliding cavity 5. A conductive rod 13 is fixedly installed at the upper end of the electric slider 11, and the upper end of the conductive rod 13 is fixedly connected to a conductive sheet 6. A conductive plate 7 is fixedly installed on each of the two conductive sheets 6. Through the cooperation of the measuring chamber 4, the electric slider 11, the conductive sheet 6 and the conductive plate 7, electrodes of different specifications can be directly placed into the measuring chamber 4 and then made conductive. Due to the different conductivity, the current passing through them will be different, and the magnetic field generated around them will also be different. By observing and reflecting the magnitude of their magnetic field, the conductivity of different electrodes can be compared.

[0025] A conductor tube 8 is fixed between the sliding cavity 5 and the relay box 2. A conductive wire 12 is installed inside the conductor tube 8. A reaction mechanism is also installed inside the lower wall of the measuring chamber 4. Through the setting of the reaction mechanism, when a magnetic field is generated around the conductive electrode, different electrodes will have different currents flowing through them, resulting in different magnetic field strengths. This further causes different directional forces on the magnetic needle 18. Under the resistance of the light spring 19, the electrode conductivity can be determined by observing the rotation angle of the highly sensitive magnetic needle 18, which is very convenient and saves a lot of time and labor. The reaction mechanism includes a vacuum chamber 15 fixedly installed inside the lower wall of the measuring chamber. A support base 16 is fixedly installed on the lower wall of the vacuum chamber 15. A rotating shaft 17 is rotatably installed on the upper end of the support base 16. A highly sensitive magnetic needle 18 is fixedly installed on the rotating shaft 17. A light spring 19 is fixed on each of the two side walls. The other ends of the two light springs 19 are fixed on the opposite side walls of the vacuum chamber 15. The reaction structure is set at the center of the lower wall of the measuring chamber 4. A rotating rod 9 is rotatably set on the upper wall of the shell 1. A cover plate 10 is fixed on the rotating rod 9. The cover plate 10 is made of insulating material and is tightly fitted to the shell 1. Since the conductivity of some electrodes is easily affected by external impurities, the cover plate 10 effectively prevents external impurities from contacting the electrodes, thereby affecting the conductivity of the electrodes and making the detection data inaccurate. At the same time, if the electrodes have weak connections with the outside, it will also have an adverse effect on the detection data. Therefore, the insulating cover plate 10 effectively prevents this from happening. The cover plate 10 is set correspondingly to the measuring chamber 4.

[0026] A locking mechanism is provided between the end of the cover plate 10 away from the rotating rod 9 and the upper wall of the housing 1. This locking mechanism isolates the measuring chamber 4 from the outside environment when the cover plate 10 is placed on it, preventing impurities from entering the measuring chamber 4 and causing changes in the conductivity of the electrodes. It also effectively prevents leakage. The locking mechanism includes a rubber plug 20 fixedly mounted on the lower wall of the cover plate 10. The end of the rubber plug 20 away from the rotating rod 9 is located. The upper wall of the housing 1 has a matching locking cavity 21, in which the rubber plug 20 is locked. The material of the rubber plug 20 is... The material is natural rubber, and the shapes of the cavity 21 and the rubber plug 20 are matched with an ellipsoidal shape. Because natural rubber has excellent resilience, insulation, water resistance and plasticity, and after proper treatment, it also has valuable properties such as oil resistance, acid resistance, alkali resistance, heat resistance, cold resistance, pressure resistance and wear resistance. Therefore, the use of natural rubber for the rubber plug 20 can greatly increase its service life and increase the tightness of the device. At the same time, the ellipsoidal shape of the cavity 21 and the rubber plug 20 prevents the rubber plug 20 from falling out of the cavity 21 at will, increasing the stability of the device structure.

[0027] In this invention, when using the device, first open the cover plate 10 to disengage the rubber stopper 20 from the clamping cavity 21. Then, place the electrode to be tested into the measuring chamber 4, and then close the cover plate 10. When the cover plate 10 is placed on the measuring chamber 4, it isolates the measuring chamber 4 from the outside environment, preventing impurities from entering the measuring chamber 4 and causing changes in the conductivity of the electrode. It also effectively prevents leakage. Then, power is supplied to the device through the power cord 3 and the relay box 2. Under the action of the return spring 14, the conductive sheet 6 and the conductive plate 7 clamp the electrode, and the electrode can be energized through the conductive sheet 6 and the conductive plate 7, allowing electrodes of different sizes and specifications to be tested. The electrodes can be securely clamped within chamber 4, ensuring they remain in the center of the measuring chamber. Due to differences in conductivity, the magnitude of the current flowing through them varies, resulting in different magnetic field strengths. By observing and assessing the magnitude of these magnetic fields, the conductivity of different electrodes can be compared. When an electrode conducts electricity and generates a magnetic field, different electrodes result in different currents flowing through them, leading to different magnetic field strengths. This, in turn, causes different directional forces on the magnetic needle 18. With the resistance of the light spring 19, the conductivity of the electrodes can be determined by observing the rotation angle of the highly sensitive magnetic needle 18. This method is very convenient and saves a significant amount of time and labor.

[0028] In addition to the embodiments described above, the present invention may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
