Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example one
Referring to fig. 3, the water quality detecting apparatus of the first embodiment includes an installation pipe 9 and a water quality detecting probe. The installation pipe 9 comprises a water inlet pipe section 901, a water outlet pipe section 903 and a connecting pipe section 902 which is communicated with the water inlet pipe section and the water outlet pipe section. The cross-sectional area of the water inlet pipe segment 901 is larger than the cross-sectional area of the connecting pipe segment 902. The water quality detection probe is arranged on the connecting pipe section and extends into the connecting pipe section.
The water quality detecting device is connected into a pipeline through a mounting pipeline 9 instead of being combined with a water tank. Because the joint of the water quality detection device and the water tank is easy to leak in the traditional technology, the water quality detection device is prevented from being combined with the water tank, and further the leakage at the joint can be avoided. In addition, this kind of water quality testing device, because the cross sectional area of the pipeline section of intaking is greater than the cross sectional area of connecting the pipeline section, and then the velocity of flow in the middle of the connecting pipe section is greater than the velocity of flow of the pipeline section of intaking, rivers in the middle of the connecting pipe section have realized local acceleration for the water quality testing probe that stretches into in the connecting pipe section receives rivers and erodees, avoids producing the impurity deposit on water quality testing probe surface, with the detection precision that improves water quality testing device. Wherein, to rivers acceleration at connecting pipe section department, the water current that main aim at assurance water quality testing probe department has big velocity of flow. In addition, the water quality detection probe is not affected by impurity accumulation, so that the service life of the water quality detection device can be prolonged.
Wherein, the water quality detection probe is arranged on the connecting pipe section and extends into the connecting pipe section, and the water quality detection probe can contact with the liquid in the connecting pipe section, including the condition that the end part of the water quality detection probe is flush with the inner wall of the connecting pipe section and the condition that the end part of the water quality detection probe protrudes relative to the inner wall of the connecting pipe section.
Referring to fig. 3, the water quality detecting probe is an electrode pair 3, and the electrode pair 3 is coaxially disposed. In this case, the two electrodes are subjected to the same scouring, thereby preventing the upstream electrode from being more easily damaged.
In fig. 3, the electrode pair 3 is connected to the circuit through a lead 1.
It is also found from fig. 3 that the connecting tube section is locally outwardly convex forming a mounting recess for the electrode pair 3. The electrode pair 3 is mounted into mounting recesses, wherein the electrode pair 3 includes a positive electrode and a negative electrode, and the number of the mounting recesses is two, for mounting the positive electrode and the negative electrode, respectively. In this case, the electrode pair 3 is reliably installed, hardly affected by water flow scouring, and further the service life of the water quality detection device can be prolonged.
In fig. 3, the ends of the positive and negative electrodes of the electrode pair 3 protrude from the inner wall of the connecting pipe section. This kind of condition can guarantee that electrode pair 3 fully contacts with rivers to carry out accurate measuring to quality of water. Of course, the end of the positive electrode and the end of the negative electrode of the electrode pair 3 can be flush with the inner wall of the connecting pipe section, so that the electrode pair 3 can be prevented from being washed by water flow, and the service life of the water quality detection device is ensured.
In fig. 3, the inner walls of the water inlet pipe section and the water outlet pipe section are both provided with a first groove and a second groove. Wherein, a clamping ring 5 is fixed in the first groove, and a sealing ring 8 is fixed in the second groove.

Wherein, the function of rand 5 mainly lies in locking installation pipeline 9 and pipeline, and the function of sealing washer 8 mainly lies in realizing installing the sealed between pipeline 9 and the pipeline, prevents the hourglass.
According to a first embodiment of the invention, the first recess is located on a side of the second recess remote from the connecting pipe section. In this case, for installation pipeline 9, first recess is located the outside of second recess, also is that rand 5 is located the outside of sealing washer 8, and then can be better the sealed effect of assurance sealing washer 8. Wherein, when the cross sections of the water inlet pipe section and the water outlet pipe section are circular (neglecting the wall thickness of the water inlet pipe section and the water outlet pipe section), the sealing ring 8 can be an O-shaped sealing ring 8.
Of course, the installation pipe 9 and the pipeline may be connected by other clamping, screwing, welding or bonding methods, besides the above mentioned sealing connection by the collar 5 and the sealing ring 8. For example, when other clamping methods are used, the installation pipe 9 and the pipe section of the pipeline which is matched with the installation pipe 9 can be clamped by a clamp. For another example, when the threaded connection mode is adopted, the ends of the water inlet pipe section and the water outlet pipe section are both provided with internal threads/external threads, and the pipeline is provided with external threads/internal threads matched with the internal threads/external threads.

The difference from the first embodiment is that in the third embodiment, referring to fig. 5, in order to make the flow rate of the connecting pipe section 902 greater than that of the water inlet pipe section 901 when water flows into the installation pipe 9, the water inlet pipe section 901 and the connecting pipe section 902 extend along different axes, and the water inlet pipe section 901 and the connecting pipe section 902 satisfy the following conditions: when water flow is introduced into the installation pipeline 9, the gravitational potential energy of the reclaimed water in the water inlet pipe section is higher than that of the reclaimed water in the connecting pipe section. Here, "the gravitational potential energy of the water in the water inlet pipe section is higher than that of the water in the connecting pipe section" is for the same amount of material of water.
From this, in fig. 5, when rivers flowed to the connection pipeline section from the intake pipe section, the partial gravitational potential energy of water converted into the kinetic energy of water, and then made the speed of rivers increase in the middle of the connection pipeline section to make the quality of water measuring probe that stretches into in the connection pipeline section receive rivers to erode, avoid producing the impurity deposit on quality of water measuring probe surface, with the detection precision that improves quality of water measuring device.

Furthermore, even if a small amount of impurities are carried in the water flow or a small amount of organic matters are bred, the impurities or the organic matters are only cut off in the water inlet pipe section, and further the organic matters are prevented from being deposited at the water quality detection probe when the water flow passes through the connecting pipe section. And, because the pipeline section of intaking designs into the curve pipeline section, and then the velocity of flow in the middle of the connecting pipe section can be greater than the velocity of flow in the middle of the pipeline section of intaking for rivers wash water quality testing probe, further avoid organic matter deposit in water quality testing probe department.
