Description

Technical Field

[0001] The utility model relates to the technical field of conductivity sensors, in particular to a flushing type range - adjustable conductivity sensor. Background Technique

[0002] Conductivity sensors can be divided into electrode - type conductivity sensors, inductive conductivity sensors, and ultrasonic conductivity sensors according to different measurement principles and methods. The electrode - type conductivity sensor uses the resistance measurement method according to the electrolytic conduction principle to measure conductivity. Its conductance measurement electrode behaves as a complex electrochemical system during the measurement process. The existing electrode - type conductivity sensor has an unchangeable measurement range and cannot adapt to the measurement of different conductivities. Electrode polarization is likely to occur during the measurement process. Since the measurement object is a liquid, a fixing device needs to be additionally set during measurement, which is inconvenient to operate.

[0003] The prior art discloses a flushing type range - adjustable conductivity sensor of CN202223382538.2, which includes a probe head, a range adjustment device, and a flushing device. The probe head includes a probe head housing, electrodes, leads, and a circuit board. The range adjustment device includes a driving mechanism, a hollow rod, and an adjustment block. A liquid - passing hole is arranged in the probe head housing, and the electrodes are symmetrically arranged on both sides of the liquid - passing hole. The adjustment block can move along the extension direction of the liquid - passing hole under the drive of the driving mechanism. The flushing device includes a pipeline and an extrusion mechanism for driving the measured liquid in the pipeline to flow. The flushing type range - adjustable conductivity sensor of the utility model has an adjustable range, can adapt to the measurement of different conductivities, and changing its measurement range can make the measurement more accurate; it has flushing and stirring, can make the liquid to be measured uniform, so the electrode polarization phenomenon can be reduced; it can float freely on the liquid surface without fixation, and the operation is convenient.

[0004] The above - mentioned prior art has the following disadvantages: Since the position of the water inlet pipe is fixed, it is impossible to detect the conductivity of liquids at different depths, which is inconvenient for actual use; for this reason, this application proposes a flushing type range - adjustable conductivity sensor.

[0020] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0021] AsFigures 1 - 3 As shown in the figure, an embodiment of the utility model provides a flushing type range-adjustable conductivity sensor, which includes:

[0022] A conductivity sensor body 1, and a water inlet pipe 2 is installed at the bottom of the conductivity sensor body 1;

[0023] A water inlet assembly capable of adjusting the water inlet depth; the water inlet assembly includes a connecting pipe 5 that can be detachably connected to the water inlet pipe 2. A rubber ring is fixed on the outer wall of the connecting pipe 5. The connecting pipe 5 is slidably connected in the water inlet pipe 2 and the rubber ring is slidably abutted against the inner wall of the water inlet pipe 2, so as to ensure the sealing performance between the connecting pipe 5 and the water inlet pipe 2;

[0024] An explanation of the detachable connecting pipe 5: A plug pin 7 that is slidably connected to the water inlet pipe 2 is provided through the water inlet pipe 2, and a jack is provided on the water inlet pipe 2. The plug pin 7 is slidably connected in the jack; A locking groove 8 is provided through the connecting pipe 5, and the plug pin 7 is slidably connected in the locking groove 8 to connect the connecting pipe 5 and the water inlet pipe 2. A pulling block 6 is fixedly connected to the plug pin 7, and a spring 9 is fixed on the pulling block 6. The other end of the spring 9 is connected to the water inlet pipe 2. The spring 9 is sleeved outside the plug pin 7. In this way, the spring 9 generates a pulling force on the pulling block 6, and further generates a pulling force on the plug pin 7, so that the plug pin 7 is stably stuck in the locking groove 8, thereby ensuring the stability of the connection between the water inlet pipe 2 and the connecting pipe 5;

[0025] When it is necessary to disassemble the water inlet pipe 2 and the connecting pipe 5, the staff manually pulls the pulling block 6, and the movement of the pulling block 6 drives the movement of the plug pin 7, so that the plug pin 7 disengages from the locking groove 8. At this time, the connecting pipe 5 is no longer locked, and the connecting pipe 5 can be moved downward to be disassembled from the water inlet pipe 2;

[0026] Among them, the rubber ring is arranged above the locking groove 8. Such a setting also has a sealing effect on the part where the locking groove 8 and the plug pin 7 slide, and further improves the stability of water inlet;

[0027] The other end of the connecting pipe 5 is installed with an adjusting pipe 3 that can adjust its shape and can maintain the adjusted shape. A short pipe 4 is installed on the adjusting pipe 3. The adjusting pipe 3 is a shaped flexible pipe. By adjusting the shape of the adjusting pipe 3, the position of the short pipe 4 can be adjusted, so that the conductivity of liquids at different depths can be adjusted. The adjusting pipe 3 is convenient to adjust and can be shaped, which can meet the use requirements and is also convenient to disassemble for storage.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
