Description

Technical Field

[0001] This new type generally relates to the field of instruments and meters, and specifically relates to an on-line water quality conductivity and pH integrated sensor. Background Art

[0002] Currently, there are two methods for testing the conductivity and pH of water quality, namely the laboratory analysis method and the in-situ electrode measurement method.

[0003] If the laboratory analysis method is adopted, a conductivity meter and a pH meter are respectively required to measure the conductivity and pH of water quality. Both the conductivity meter and the pH meter are laboratory instruments with high measurement accuracy, but the test cycle is relatively long. Using two devices not only occupies space but also has a high monitoring cost.

[0004] If the in-situ electrode measurement method is adopted, a pH electrode and a conductivity electrode need to be respectively connected to the corresponding analysis instrument system. Since the two are two independent systems, there are also problems of large space occupation and high monitoring cost. Summary of the Utility Model

[0005] In view of the problems existing in the above-mentioned prior art according to this new type, an on-line water quality conductivity and pH integrated sensor is provided, including: a transmitter and an integrated electrode connected to the transmitter. The integrated electrode includes an electrode housing with one end open; a glass bulb composite electrode fixed inside the electrode housing; and a probe, with at least two probes fixed inside the battery housing. The glass bulb composite electrode and the probe are both electrically connected to the transmitter. By having the above technical features, the integrated electrode integrates both a glass bulb composite electrode that can measure the pH of water quality and a probe for measuring the conductivity of water quality. The integrated electrode sends the two signals into the transmitter, and the transmitter processes the two signals and finally transmits them to a data collector or a controller. Due to the design of the integrated sensor, compared with the traditional laboratory analysis method or the in-situ electrode measurement method, the integration of multiple systems is realized, not only the volume is small, but also the cost is saved, and the monitoring efficiency is greatly improved.

[0006] In some embodiments, the glass bulb composite electrode is coaxially arranged inside the electrode housing, the probe is arranged in the gap between the glass bulb composite electrode and the inner wall of the electrode housing, and adjacent probes are arranged at intervals. Thus, while realizing the synchronous operation of the glass bulb composite electrode and the probe, they do not interfere with each other, ensuring the independent and normal operation of the two sensors, and it is not easy to be damaged.

[0007] In some embodiments, a plug electrically connected to the internal chip is provided at one end of the transmitter, a jack for accommodating the plug is provided at the end of the electrode housing facing away from the outlet, and a contact point electrically connected to the probe and the glass bulb composite electrode is provided on the inner wall of the jack. Thus, the integrated setting of the transmitter and the integrated electrode is realized by the mutual plugging of the transmitter and the electrode housing, which not only has a compact structure and eliminates the unstable factor of line connection damage, but also improves the maintenance efficiency if the integrated electrode is damaged, facilitates the replacement of parts, and improves the maintenance efficiency.

[0008] In some embodiments, the transmitter is provided with a receiving groove at the end of the plug, the plug is fixed at the bottom of the receiving groove, and the electrode housing is positioned at the peripheral side of the jack and is provided with a limiting groove that cooperates with the receiving groove for mutual insertion. Thus, through the mutual insertion of the receiving groove and the limiting groove, the force on the plug is greatly reduced, and it is not easy to cause damage to the plug, and the tightness of the insertion of the transmitter and the integrated electrode is also guaranteed, and it also has a certain water-blocking effect.

[0009] In some embodiments, the electrode housing further includes an upper fixing plate and a lower fixing plate, the upper fixing plate and the lower fixing plate are spaced apart and fixed on the inner wall of the electrode housing, and the probe and the glass bulb composite electrode are both inserted through the upper fixing plate and the lower fixing plate. Thus, the stability of the separate fixation of the probe and the glass bulb composite electrode is ensured by the structure of the upper fixing plate and the lower fixing plate arranged at intervals, and the two fixing plates have a water-blocking effect at the same time, ensuring the stability of the normal operation of the probe and the glass bulb composite electrode.

[0010] In some embodiments, the end of the plug is located in the receiving groove and does not exceed the edge of the receiving groove, thereby protecting the plug from being bumped by the surrounding environment and improving the durability of the transmitter.

[0011] In some embodiments, the outer contour of the housing of the transmitter is the same as the outer contour of the housing size of the electrode. Therefore, when the transmitter and the integrated electrode are plugged into each other, the outer contour transition is smoother and less likely to be scratched by foreign objects, thereby ensuring the accuracy of the monitoring indicators of the integrated electrode.

[0012] In some embodiments, the transmitter is integrated with a temperature sensor. Thus, the transmitter is integrated with the integrated electrode, and needs to be immersed in water when working. The temperature sensor can not only monitor the temperature, but also improve the accuracy of water quality temperature monitoring.

[0013] In some embodiments, a waterproof sealing ring is provided on the peripheral side of the plug, thereby ensuring the stability of signal transmission between the integrated electrode and the transmitter.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. It is convenient to replace damaged parts. Since the transmitter and the integrated electrode are detachably connected, if the integrated electrode is damaged, the damaged parts can be easily replaced by plugging, improving the maintenance efficiency;

[0016] 2. Ensure the stability of the sensor operation. Since a waterproof sealing ring is provided on the periphery of the plug, it is not easy for water to enter at the plugging part of the transmitter and the integrated electrode, ensuring the normal transmission of signals between the integrated electrode and the transmitter;

[0017] 3. Low cost. Since the integrated electrode integrates a glass bulb composite electrode and a probe, the integrated electrode has the function of simultaneously monitoring the conductivity and the pH value of water quality.

[0018] It should be understood that the content described in the new content part is not intended to limit the key or important features of the embodiments of the present disclosure, nor to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Hereinafter, preferred embodiments (or implementation manners) of the present invention will be described in detail with reference to the drawings.

[0026] The utility model provides an on-line water quality conductivity and pH integrated sensor, which includes a transmitter 1 and an integrated electrode 2 connected to one end of the transmitter 1. A plurality of probes 21 and a glass bulb composite electrode 22 are integrated inside the integrated electrode 2, and both the probes 21 and the glass bulb composite electrode 22 are electrically connected to the transmitter 1 at the tail, so as to transmit the pH data and water quality conductivity data of the monitored water quality to the inside of the transmitter 1 in real time, realizing the monitoring of multi-category parameters through a single sensor. Compared with the traditional monitoring method, it not only saves costs but also improves the monitoring efficiency.

[0027] The following refers to Figures 1-4 to describe an on-line water quality conductivity and pH integrated sensor of the utility model.

[0028] Figure 1 Fig. shows the overall structural schematic diagram of an on-line water quality conductivity and pH integrated sensor provided by an embodiment of the utility model. Refer to Figure 1 As shown, an on-line water quality conductivity and pH integrated sensor provided by this embodiment includes a transmitter 1 and an integrated electrode 2 connected to one end of the transmitter 1. The transmitter 1 adopted in this new type is an electric transmitter 1, which receives the conductivity signal and pH signal collected by the integrated electrode 2, processes the signals, and transmits them to the subsequent data collector or controller connected to the transmitter 1 in the form of characteristic signals.

[0029] Figure 2 Fig. shows the cross-sectional view of the integrated electrode 2 in an on-line water quality conductivity and pH integrated sensor provided by an embodiment of the utility model; Figure 3 Fig. shows the structural schematic diagram of the integrated electrode 2 in an on-line water quality conductivity and pH integrated sensor provided by an embodiment of the utility model. Refer to Figure 2 and Figure 3 As shown, the integrated electrode 2 includes a cylindrical electrode housing 23 with a cavity inside, and one end is a plug-in part 231 connected to the transmitter 1, and the other end is provided with an opening 232 communicating with the inner cavity of the electrode housing 23; the integrated electrode 2 also includes a glass bulb composite electrode 22 and probes 21. The glass bulb composite electrode 22 is mainly used to monitor the pH value in the water quality, and is coaxially arranged inside the electrode housing 23, and its root is fixedly connected to the electrode housing 23. The probes 21 can be set in the form of double probes 21 or in the form of four probes 21, and are mainly used to monitor the conductivity in the water quality. They are arranged along the length direction of the electrode housing 23 and are located in the gap between the middle glass bulb composite electrode 22 and the inner wall of the electrode housing 23, and are arranged at intervals around the glass bulb composite electrode 22.

[0030] In order to firmly fix the glass bulb composite electrode 22 and the probe 21 in the integrated electrode 2 while ensuring the stability of their respective operations, an upper fixing plate 3 and a lower fixing plate 4 are further provided inside the electrode housing 23. The upper fixing plate 3 and the lower fixing plate 4 are arranged at intervals and are both tightly fixed on the inner wall of the electrode housing 23. The above-mentioned glass bulb composite electrode 22 and multiple probes 21 penetrate through the upper fixing plate 3 and the lower fixing plate 4 and are tightly connected to the upper fixing plate 3 and the lower fixing plate 4, thereby realizing the separate fixing of the glass bulb composite electrode 22 and multiple probes 21. Moreover, since the upper fixing plate 3, the lower fixing plate 4, the glass bulb composite electrode 22 and the probe 21 are all tightly connected, it is not easy to generate gaps at the connection part. Therefore, when the integrated electrode 2 is placed in water, the liquid is not easy to penetrate into the interior of the electrode housing 23, ensuring the stable operation of the integrated electrode 2.

[0031] Figure 4 The cross-sectional view of the transmitter 1 in an on-line water quality conductivity and pH integrated sensor provided by the embodiment of the present invention is shown. Refer to Figure 4 As shown, the transmitter 1 is a cylindrical device. One end thereof inserted into the integrated electrode 2 is provided with a plug 11. The plug 11 can be a 2.5 mm headphone plug 11, which is coaxially fixed at the end of the transmitter 1 and is electrically connected to the chip circuit inside the transmitter 1. On the end face of the insertion part 231 of the electrode housing 23 in the integrated electrode 2, a jack 233 matching the plug 11 is opened. The jack 233 is coaxially arranged with the electrode housing 23, and a plurality of electrical contact points electrically connected to the glass bulb composite electrode 22 and multiple probes 21 are arranged on the inner wall of the jack 233. Thus, through the mutual insertion of the transmitter 1 and the integrated electrode 2, the signal transmission between the monitoring data of the integrated electrode 2 and the transmitter 1 is realized. Moreover, a ring-shaped waterproof sealing ring 5 is embedded on the circumferential side of the root of the plug 11, ensuring the stability of signal transmission after the transmitter 1 and the integrated electrode 2 are mutually inserted. The other end of the transmitter 1 is provided with a waterproof socket 12 for electrically connecting to a data collector or a controller.

[0032] In order to improve the stability of the mutual insertion between the transmitter 1 and the integrated electrode 2, a circular receiving groove 13 is provided at the end of the plug 11 of the transmitter 1. The end of the plug 11 is fixed on the bottom arm of the receiving groove 13, and the head of the plug 11 is located inside the receiving groove 13 and does not exceed the edge of the receiving groove 13, thus playing a protective role for the plug 11. For the insertion part 231 of the electrode housing 23 in the integrated electrode 2, a limiting groove 234 matching the receiving groove 13 is provided on its circumferential side. After the transmitter 1 and the integrated electrode 2 are mutually inserted, while ensuring the tightness of the insertion between the transmitter 1 and the integrated electrode 2, it also reduces the force on the overall structure by the plug 11 and improves the firmness of the connection between the plug 11 and the transmitter 1. Moreover, the diameter of the outer contour of the transmitter 1 is the same as that of the outer contour of the integrated electrode 2, so that after the transmitter 1 and the integrated electrode 2 are mutually inserted, the connection part is smoother, not easily rubbed against the external environment, and reduces the influence of foreign matter aggregation at the opening 232 of the electrode housing 23 on the monitoring data. And due to the adoption of the insertion connection method, if the integrated electrode 2 or the transmitter 1 is damaged, it is also convenient for personnel to maintain and replace, greatly improving the maintenance efficiency.

[0033] Moreover, the chip circuit in the transmitter 1 adopts measures such as time-sharing measurement and circuit isolation, so that when the integrated electrode 2 works, the pH measurement is not easily interfered, ensuring the accuracy of the pH acidity and alkalinity measurement. And a temperature sensor is also integrated on the chip circuit, so that when the transmitter 1 and the integrated electrode 2 are inserted and immersed in water, it can not only monitor the conductivity and pH acidity and alkalinity in the water quality, but also monitor parameters such as the water temperature.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

[0035] The above are only the preferred embodiments of this application and are not used to limit this application.
