Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a water quality monitoring device for a municipal pipe network system. Background Technique

[0002] The water quality monitoring device of the municipal pipe network system is a key water service management tool, which is composed of a variety of sensors, a data acquisition unit, a communication module and a data processing unit. The sensors are responsible for measuring key parameters of the water body, such as pH value, dissolved oxygen and conductivity. The data acquisition unit transmits this data to the data processing unit, and the communication module realizes real-time remote monitoring. Its working principle is based on physical, chemical and biological measurement methods, and different sensors use different technologies to detect water quality parameters. The data processing unit performs data filtering, calibration and merging to generate information that can be used for reporting, alarming and decision support. However, when the current water quality monitoring device is installed at the end of the drainage pipe of the municipal pipe network system for use, due to the large drainage pressure of the drainage pipe of the municipal pipe network system, the water source directly generates a large impact force on the sensor probe of the water quality monitoring device. At this time, the sensor probe is affected by high water pressure for a long time, and each component of the probe may not withstand the erosion of the pressure, resulting in the equipment being more prone to failure, reducing the reliability of the entire water quality monitoring system. Moreover, the water flow velocity in the drainage pipe is large and the drainage pressure fluctuates significantly, which will cause some parameters in the water body, such as dissolved oxygen, to fluctuate violently instantaneously, affecting the accuracy of the monitoring data. Content of the Utility Model

[0003] The purpose of the utility model is to provide a water quality monitoring device for a municipal pipe network system, and a buffer device is adopted at the connection between the sensor probe of the water quality monitoring device and the drainage pipe to slow down the drainage impact force, so as to solve the problems put forward in the above background technique.

An internally threaded pipe is fixed in the annular structure formed by the lower pipe holder and the holding ring. A drainage cavity is arranged between the upper hoop and the holding ring. An externally threaded water guide pipe is installed inside the internally threaded pipe in a threaded manner. One end of the externally threaded water guide pipe away from the internally threaded pipe is fixed with a rear housing. An internally hollow protective shell is fixed on the outer wall of the externally threaded water guide pipe close to the rear housing. A water quality sensor is installed inside the internally hollow protective shell.

[0005] Preferably, a bottom plate is fixed on the outer wall of one side of the lower support seat close to the inner threaded pipe, and a water quality monitor is installed at the bottom end of the bottom plate. The input end of the water quality monitor is electrically connected to the output end of the water quality sensor.

[0006] Preferably, the lower support seat, the lower holding pipe, the upper hoop and the holding ring are all made of components made of aluminum alloy material.

[0007] Preferably, four water passing holes communicating with the rear housing are arranged inside the external threaded water pipe.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-4 , an embodiment provided by the present invention: a water quality monitoring device for a municipal pipe network system, including a lower support base 1 and a lower pipe clamp 2 fixed to the top of the lower support base 1, and an upper pipe hoop 3 is installed on one side of the top of the lower pipe clamp 2. The upper pipe hoop 3 and the lower pipe clamp 2 are bolted through a positioning pin 4. The device is fixedly connected to the end of the drain pipe through the lower pipe clamp 2, the upper pipe hoop 3 and the positioning pin 4. Its installation is quick and convenient, facilitating the installation and use by the staff. The staff can firmly hold the device through the lower pipe clamp 2 and the upper pipe hoop 3 at the end position of the drain pipe in the municipal pipe network system, and then use the positioning pin 4 to bolt the lower pipe clamp 2 and the upper pipe hoop 3;

[0018] A holding ring 5 is fixed to the other side of the top of the lower pipe clamp 2. An internal threaded pipe 7 is fixed in the annular structure formed by the lower pipe clamp 2 and the holding ring 5. The lower support base 1, the lower pipe clamp 2, the upper pipe hoop 3 and the holding ring 5 are all made of components of aluminum alloy material;

[0019] A drainage cavity 6 is arranged between the upper pipe hoop 3 and the holding ring 5. An external threaded water guide pipe 10 is threadedly installed inside the internal threaded pipe 7. One end of the external threaded water guide pipe 10 away from the internal threaded pipe 7 is fixed with a rear housing 11. The drainage cavity 6 can directly remove most of the water source impact force; the water passing hole 1001 serves the purpose of guiding the water source, enabling the water source to smoothly enter the external threaded water guide pipe 10 and the rear housing 11;

[0020] An internal hollow protective shell 16 is fixed to the outer wall of one side of the external threaded water guide pipe 10 close to the rear housing 11. A water quality sensor 15 is installed inside the internal hollow protective shell 16. A valve stem 13 for blocking the opening end of the internal hollow protective shell 16 is elastically installed inside the rear housing 11;

[0021] When the drain pipe drains water, the water source discharged from the drain pipe in the municipal pipe network system enters the internal threaded pipe 7 and the external threaded water guide pipe 10 through the drainage cavity 6. During this process, the drainage cavity 6 can discharge most of the water flow, thereby initially slowing down the impact force and water flow rate of the water flow. At this time, some water sources still enter the external threaded water guide pipe 10 and the rear housing 11. The remaining water source impact force of this part will force the helical spring 12 to be compressed, then the valve stem 13 and the retaining cap 14 will move to the right, and further make the end of the internal hollow protective shell 16 in an open state, that is, the water source enters the internal hollow protective shell 16 through the opening of the internal hollow protective shell 16. At this time, the water quality sensor 15 measures various key parameters of the water body;

[0022] A bottom plate 8 is fixed on the outer wall of one side of the lower support base 1 close to the internal thread pipe 7, and a water quality monitor 9 is installed at the bottom end of the bottom plate 8. The input end of the water quality monitor 9 is electrically connected to the output end of the water quality sensor 15. The water quality sensor 15 measures various key parameters of the water body, such as pH value, dissolved oxygen, and conductivity, etc. The detected numerical information is sent into the water quality monitor 9 for analysis and display;

[0023] Four water passing holes 1001 communicating with the rear housing 11 are arranged inside the external thread water pipe 10;

[0024] A spiral spring 12 is installed on the inner wall of one side of the rear housing 11. One end of the surface of the valve stem 13 is fixed with a retaining cap 14. One end of the spiral spring 12 is fixedly connected to the outer wall of one side of the retaining cap 14. One end of the valve stem 13 extends into the interior of the inner hollow protective shell 16, and the other end of the valve stem 13 penetrates to the outside of the rear housing 11 and is fixed with a retaining disc;

[0025] Round holes are formed on the outer walls around the inner hollow protective shell 16. The water source generates an impact force on the retaining cap 14, and causes the retaining cap 14 to drive the valve stem 13 to move rightward. At this time, the spiral spring 12 is in a compressed state. When the water source pressure decreases, the spiral spring 12 resets and causes the valve stem 13 to re-enter the inner hollow protective shell 16. At this time, the inner hollow protective shell 16 is in a closed state. After the inner hollow protective shell 16 is closed, the water source retained in the inner hollow protective shell 16 can be discharged through the round holes.

[0026] When the embodiment of the present application is in use, first, the staff makes the device firmly held at the end position of the drainage pipe in the municipal pipe network system through the lower pipe holder 2 and the upper pipe hoop 3, and then uses the positioning pin 4 to bolt the lower pipe holder 2 and the upper pipe hoop 3. Then, the staff takes out the external thread water guide pipe 10 again and thread-assembles the external thread water guide pipe 10 into the internal thread pipe 7, thus completing the installation of the device and the drainage pipe in the municipal pipe network system. When the drainage pipe drains water, the water discharged from the drainage pipe in the municipal pipe network system enters the internal thread pipe 7 and the external thread water guide pipe 10 through the drainage cavity 6. In this process, the drainage cavity 6 can discharge most of the water flow, thereby initially reducing the impact force and water flow rate of the water flow. At this time, some water still enters the external thread water guide pipe 10 and the rear housing 11. The impact force of this part of the remaining water source will force the helical spring 12 to be compressed, so that the valve stem 13 and the retaining cap 14 move to the right, and then the end of the inner hollow protective shell 16 is in an open state, that is, the water source enters the inner hollow protective shell 16 through the opening of the inner hollow protective shell 16. At this time, the water quality sensor 15 measures various key parameters of the water body, such as pH value, dissolved oxygen, and conductivity, etc. The detected numerical information is sent to the water quality monitor 9 for analysis and display. In this process, the settings of components such as the drainage cavity 6 and the helical spring 12 can reduce the water flow impact force at the connection between the water quality sensor 15 and the drainage pipe, effectively protecting the sensor components and preventing them from being damaged due to excessive pressure. Moreover, in this process, the water quality sensor 15 can measure the water quality parameters more accurately in a relatively stable environment without being interfered by external impacts, thereby improving the stability and reliability of the monitoring system.
