Description

Technical Field

[0001] This utility model relates to the technical field of conductivity measurement, and in particular to a device for measuring the conductivity of pure water. Background Technology

[0002] In numerous fields such as industrial production, scientific research experiments, and water quality monitoring, the conductivity of pure water is a key indicator. It reflects the ion content in water, thereby demonstrating the purity of the water. Therefore, accurate measurement of pure water conductivity is crucial, leading to the development of pure water conductivity measuring devices. These devices, through precise sensors and advanced electronic technology, can quickly and accurately detect the ion concentration in water, thereby assessing water purity. In high-precision fields such as semiconductor manufacturing, pharmaceutical production, and laboratory analysis, the conductivity of pure water directly affects product quality and experimental results, making the application of such devices particularly important. Modern conductivity measuring devices typically have temperature compensation functions to eliminate the influence of temperature changes on measurement results, while also supporting data recording and transmission for real-time monitoring and long-term analysis, providing strong technical support for water quality control in various industries.

[0003] Currently, in traditional pure water conductivity measuring devices, the power supply provides electrical energy for the entire measurement process, while the transformer is used to adjust the voltage to meet the electrical conditions required for the measurement. Electrode rods are inserted into the pure water, and the conductivity of the pure water is measured by combining the conductive circuit formed by the electrodes and the pure water with a multimeter.

[0004] The aforementioned existing technical solutions have the following drawbacks: Since the measurement process involves electrical equipment such as power supplies and transformers, if operators directly contact the electrical equipment, especially the electrode rods, without adequate preparation, there is a high possibility of electric shock accidents. Utility Model Content

[0005] The purpose of this invention is to provide a pure water conductivity measuring device to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A pure water conductivity measuring device comprises a power supply, a transformer, a positive metal rod, a negative metal rod, and a multimeter. The power supply and the transformer are electrically connected via wires. The positive and negative metal rods are respectively wired to the positive and negative output terminals of the transformer. A safety detection module is provided on the negative metal rod. The safety detection module includes a mounting sleeve, an insulating handle, a capacitance sensing diaphragm, and an insulating cover. The sleeve has a shaft hole for mounting one end of the negative metal rod. The insulating handle is sleeved on the outside of the mounting sleeve, the capacitance sensing diaphragm is covered on the outside of the insulating handle, and the insulating cover is sleeved on the outside of the capacitance sensing diaphragm.

[0008] By adopting the above technical solution, when someone holds the insulated handle, it will press the capacitive sensing membrane. Through the sensing of the pressing area, it can know whether it is in the state of being held by a person. If it is in the state of being held by a person, the feedback is sent to the control system to prevent the equipment from starting, especially the transformer, thus providing a safer and more reliable guarantee for the measurement of pure water conductivity.

[0009] In a further embodiment, the transformer includes a housing and a boost module disposed inside the housing. The input terminal of the boost module is connected to a power source, and the output terminal of the boost module is connected to a positive metal rod and a negative metal rod.

[0010] In a further embodiment, the multimeter is provided with a positive test probe and a negative test probe, both of which are metal clips. The positive test probe is clipped to the bottom end of the positive metal rod, and the negative test probe is clipped to the bottom end of the negative metal rod.

[0011] In a further embodiment, an electric field sensing lamp is provided on the top of the transformer, which lights up when it senses that the transformer is working.

[0012] By adopting the above technical solution, the safety of this device is further increased.

[0013] In a further embodiment, the positive electrode metal rod is provided with a safety detection module identical to that of the negative electrode metal rod.

[0014] In a further embodiment, the positive electrode metal rod and the negative electrode metal rod are made of the same material.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting safety detection modules on the negative and positive metal rods, when someone holds the insulated handle, the capacitive sensing membrane will be pressed. The sensing of the pressed area can detect whether a person is holding the handle. If a person is holding the handle, the feedback is sent to the control system to prevent the equipment from starting, especially the transformer. This reduces the risk of electric shock from the source and provides a safer and more reliable guarantee for the measurement of pure water conductivity.

[0017] 2. By installing an electric field induction device on the top of the transformer and then debugging the device, it is easier to observe the transformer's operation, which can further improve the safety of the device. Attached Figure Description

[0023] Example 1:

[0024] like Figures 1-2 As shown, a pure water conductivity measuring device comprises a power supply 1, a transformer 2, a positive metal rod 3, a negative metal rod 4, and a multimeter 5. The power supply 1 and the transformer 2 are electrically connected via wires. The positive metal rod 3 and the negative metal rod 4 are respectively wired to the positive and negative terminals of the transformer 2. A safety detection module 6 is provided on the negative metal rod 4. The safety detection module 6 includes a mounting sleeve 61, an insulating handle 62, a capacitance sensing membrane 63, and an insulating covering sleeve 64. The sleeve 61 is provided with a shaft hole for mounting one end of the negative metal rod 4. The insulating handle 62 is sleeved on the outside of the mounting sleeve 61, and the capacitance sensing membrane 63 covers the outside of the insulating handle 62.

[0025] An insulating sheath 64 is fitted over the outside of the capacitive sensing film 63; the transformer 2 includes a housing and a boost module located inside the housing, the input terminal of the boost module is connected to the power supply 1, and the output terminal of the boost module is connected to the positive metal rod 3 and the negative metal rod 4; the multimeter 5 is equipped with a positive test pen and a negative test pen, both of which are metal clips, the positive test pen is clipped to the bottom end of the positive metal rod 3, and the negative test pen is clipped to the bottom end of the negative metal rod 4; an electric field sensing lamp is installed on the top of the transformer 2, which lights up when it senses that the transformer 2 is working; a safety detection module 6 identical to that of the negative metal rod 4 is installed on the positive metal rod 3, and the positive metal rod 3 and the negative metal rod 4 are made of the same material.

[0026] Specific implementation process: First, connect power supply 1 and transformer 2 electrically via wires to ensure stable power transmission. Next, install the positive metal rod 3 and negative metal rod 4 onto the positive and negative terminals of transformer 2's output, respectively. Install the safety detection module 6 on the negative metal rod 4. Insert one end of the negative metal rod 4 into the shaft hole of the mounting sleeve 61 to fix it inside the sleeve. Then, sequentially install the insulating handle 62, the capacitor sensing film 63, and the insulating cover 64, ensuring that all components are installed in place and fit tightly to prevent electric shock to the operator during measurement. In the same way, install the same safety detection module 6 on the positive metal rod 3 as on the negative metal rod 4. Clamp the positive and negative test leads of the multimeter 5 to the bottom ends of the positive and negative metal rods 3 and 4, respectively, to prepare for subsequent measurements. After assembly, the device is debugged. Power supply 1 is turned on, and transformer 2 starts working. Observe whether the electric field induction light on the top of transformer 2 is lit. If it is lit, it means that transformer 2 is working normally. At the same time, check whether the safety detection module 6 is working normally. The operator holds the insulated handle 62 of the positive metal rod 3 and the negative metal rod 4 and presses the capacitive sensing membrane 63. Through the sensing of the pressing area, the system is fed back to the control system when the hand is held, ensuring that the system can prevent the transformer 2 from starting when the hand is sensed, ensuring operational safety and not affecting the completion of subsequent measurement work. After confirming that the device is assembled and debugged correctly, the conductivity of pure water can be measured. Insert the positive metal rod 3 and the negative metal rod 4 into the pure water to be tested, and read the corresponding conductivity value through the multimeter 5 to complete the measurement of the conductivity of pure water.
