Description

Technical Field

[0001] This utility model relates to the field of municipal water supply monitoring technology, and more specifically, to an integrated monitoring device for water quality detection and water metering. Background Technology

[0002] A water quality monitor for water supply pipelines is a device used to monitor water quality parameters in water supply pipelines in real time to ensure water supply safety and quality. It is widely used in urban water supply networks, especially at key locations such as water inlets, outlets, and pipeline junctions.

[0003] Chinese patent CN221993441U discloses an online monitoring device for water quality parameters in water supply pipelines, including a main pipeline with a main flow channel formed inside. Both ends of the main pipeline have connection portions for connecting to water supply pipelines. A branch pipe is provided on the main pipeline, with a detection flow channel formed inside. The two ends of the detection flow channel are connected to the main flow channel and serve as an inlet and outlet, respectively. A protrusion is provided inside the main flow channel at the outlet of the detection flow channel to create negative pressure within the detection flow channel and allow water to enter from the inlet. A water quality sensor is provided on the side wall of the branch pipe for detecting the water in the detection flow channel. This utility model's online monitoring device for water quality parameters in water supply pipelines is compact, small in size, flexible in installation, requires no pump for diversion, and has low power consumption and cost.

[0004] This device uses one or more water quality sensors to detect the water quality in the flow channel. However, during daily use, the water quality sensors need to be maintained to ensure the accuracy of their measurement data. However, when the water quality sensors are removed from the device, water leaks from the sensor joints in the flow channel. Therefore, water needs to be shut off before maintenance, which affects the municipal water supply and leads to high operation and maintenance costs. In addition, the device does not have the function of measuring the water flow in the pipeline, so it is not convenient for staff to adjust the water flow in a timely manner to ensure the stability of the municipal water supply. Utility Model Content

[0005] This invention provides an integrated water quality detection and water metering monitoring device, which solves the technical problems of existing technologies where water quality detection sensors need to be disassembled for maintenance, which requires water outages and affects municipal water supply, resulting in high operation and maintenance costs, and lacks the function of measuring water flow in pipelines.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: An integrated water quality detection and water metering monitoring device includes a main pipeline connected to a branch pipe. Both ends of the branch pipe bend towards the main pipeline and connect to it. A water quality sensor is installed on the branch pipe. An ultrasonic flow meter is installed at the rear end of the main pipeline. A sliding cavity is provided on the branch pipe. An arc-shaped retaining ring is provided at the top of the sliding cavity. A sealing ball is provided inside the sliding cavity, and the sealing ball fits the bottom contour of the arc-shaped retaining ring. A spring is also provided in the sliding cavity, located below the sealing ball and in a compressed state. A detection probe is provided at the bottom of the water quality sensor. A first threaded connector extending above the sliding cavity is provided at the top of the arc-shaped retaining ring. A first cap that threadedly engages with the first threaded connector is provided at the bottom of the water quality sensor.

[0007] Furthermore, the branch pipe is parallel to the axis of the main pipe, and the diameter of the branch pipe is 0.3-0.5 times the diameter of the main pipe.

[0008] Furthermore, a second threaded connector is provided at the bottom of the sliding cavity, and a second cap is threadedly connected to the second threaded connector, with the bottom end of the spring connected to the second cap.

[0009] Furthermore, the bottom surface of the arc-shaped retaining ring is made of magnetic material, and the sealing ball is made of cast iron.

[0010] Furthermore, a protective sleeve is nested on the outside of the detection probe, and the surface of the protective sleeve is distributed with water-permeable holes.

[0011] Furthermore, a valve is installed on the main pipeline, and the valve is located between the inlet and outlet ends of the branch pipe.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: By setting up a main pipe, branch pipes, a water quality sensor, and an ultrasonic flow meter, some of the water flowing into the main pipe can form a tributary and circulate inside the branch pipe. The water quality sensor detects the water quality flowing through the branch pipe. When the water flow converges and flows to the rear end of the main pipe, the ultrasonic flow meter can monitor the water flow in real time. Therefore, it has both water quality detection and water flow measurement functions. Through the setting of structures such as a sliding cavity, an arc-shaped retaining ring, a sealing ball, and a spring, when the water quality sensor is removed from the branch pipe, the sealing ball can automatically seal the arc-shaped retaining ring, preventing water leakage from the branch pipe after the water quality sensor is removed. During the disassembly and maintenance of the water quality sensor, it is no longer necessary to seal the branch pipe. At this time, the water flow can still circulate inside the branch pipe without leakage. Therefore, it is easier to disassemble and maintain the water quality sensor, eliminating the need for water outages and effectively reducing operation and maintenance costs.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5An integrated water quality detection and water metering monitoring device includes a main pipe 1 with flanges at both ends, allowing the main pipe 1 to be connected to a water supply pipeline. Water flows in from the front end of the main pipe 1 and out from the rear end. A branch pipe 2 is connected to the main pipe 1, with its axis parallel to the main pipe 1 and its diameter 0.3-0.5 times that of the main pipe 1. Both ends of the branch pipe 2 bend towards the main pipe 1 and connect to it, allowing some of the water flowing into the main pipe 1 to form a tributary that circulates within the branch pipe 2. The tributary flows out from the rear end of the branch pipe 2. After exiting the main pipe, the water flow merges with the water flow in the main pipe 1 and flows together to the rear end of the main pipe 1. A water quality detection sensor 4 is installed on the branch pipe 2. In this device, the water quality detection sensor 4 includes a fluorescence dissolved oxygen sensor, a pH value measurement sensor, a turbidity sensor, and a temperature / conductivity composite sensor, which can be used to detect multiple water quality parameters of the water flow, so that the branch pipe 2 forms a water quality detection channel. An ultrasonic flow meter 5 is installed at the rear end of the main pipe 1. When the water flow merges and flows to the rear end of the main pipe 1, the ultrasonic flow meter 5 can monitor the water flow in real time, so that the device has the functions of water quality detection and water flow measurement at the same time.

[0019] In this device, a sliding cavity 6 is provided on the branch pipe 2, and an arc-shaped retaining ring 7 is provided at the top of the sliding cavity 6. A sealing ball 8 is provided inside the sliding cavity 6, and the sealing ball 8 fits the bottom contour of the arc-shaped retaining ring 7. A spring 9 is also provided in the sliding cavity 6, which is located below the sealing ball 8 and is in a compressed state. It can provide an upward elastic pushing force to the sealing ball 8, so that the sealing ball 8 can abut against the bottom of the arc-shaped retaining ring 7 under the elastic force of the spring 9. At this time, the sealing ball 8 can block the arc-shaped retaining ring 7. A detection probe 10 is provided at the bottom of the water quality detection sensor 4. When the detection probe 10 passes through the arc-shaped retaining ring 7 and extends into the interior of the sliding cavity 6, the sealing ball 8 used to block the arc-shaped retaining ring 7 will be pressed down by the detection probe 10 to the bottom of the sliding cavity 6. At this time, the detection probe 10... The probe 10 at the bottom of the water quality sensor 4 can then come into contact with the water flow in the branch pipe 2. At this time, the water quality sensor 4 can detect the water quality of the water flow in the branch pipe 2. The top of the arc-shaped retaining ring 7 is provided with a first threaded connector 11, which extends above the sliding cavity 6. The bottom of the water quality sensor 4 is provided with a first cap 12 that is threaded to the first threaded connector 11. The detection probe 10 at the bottom of the water quality sensor 4 can be inserted into the interior of the sliding cavity 6 through the first threaded connector 11, and the first cap 12 can be threaded to the top of the first threaded connector 11. At this time, the water quality sensor 4 can be fixedly installed at the top of the sliding cavity 6, and the first threaded connector 11 can be sealed, so that the water flow in the branch pipe 2 will not leak out from the first threaded connector 11 at the top of the sliding cavity 6.

[0020] During use, when it is necessary to disassemble and maintain the water quality sensor 4 installed on the branch pipe 2, simply rotate the bottom first cover 12 of the water quality sensor 4 to unscrew it from the first threaded connector 11. After the first cover 12 is separated from the first threaded connector 11, the detection probe 10 at the bottom of the water quality sensor 4 can be pulled out from the inside of the sliding cavity 6. At the same time, the arc-shaped retaining ring 7 inside the sliding cavity 6 will move upward under the elastic force of the spring 9 and abut against the bottom of the ultrasonic flow meter 5, thus automatically sealing the arc-shaped retaining ring 7. The water flow can still circulate inside the branch pipe 2 without leakage. Therefore, this device is more convenient for the disassembly and maintenance of the water quality sensor 4, eliminating the need to shut down the water supply and effectively reducing the cost of operation and maintenance.

[0021] For further details, please refer to Figure 1-5 The bottom of the sliding cavity 6 is provided with a second threaded connector 13, and a second cover 14 is threadedly connected to the second threaded connector 13. The bottom end of the spring 9 is connected to the second cover 14. The second cover 14 can be rotated off the second threaded connector 13, so that the spring 9 can be replaced. This prevents the spring 9 from losing its elasticity after long-term use, which would cause the sealing ball 8 to fail to make tight contact with the arc-shaped retaining ring 7, thus ensuring the sealing effect of the arc-shaped retaining ring 7. In addition, the bottom surface of the arc-shaped retaining ring 7 is made of magnetic material, and the sealing ball 8 is made of cast iron material. When the sealing ball 8 contacts the bottom of the arc-shaped retaining ring 7 to seal the arc-shaped retaining ring 7, the magnetic force generated by the arc-shaped retaining ring 7 will firmly attract the sealing ball 8, so that the two can make tight contact, thereby further ensuring the sealing effect of the sealing ball 8 on the arc-shaped retaining ring 7.

[0022] For further details, please refer to Figure 1-5 The detection probe 10 is nested with a protective sleeve 15. The surface of the protective sleeve 15 is distributed with water-permeable holes 16. The protective sleeve 15 can protect the detection probe 10. When the detection probe 10 is inserted into the sliding cavity 6, it can prevent the detection probe 10 from being touched by other parts, avoid damage to the detection probe 10 and ensure its working performance. In addition, the water-permeable holes 16 on the surface of the protective sleeve 15 can prevent the protective sleeve 15 from affecting the contact between the water flow and the detection probe 10.

[0023] For further details, please refer to Figure 1-5A valve 3, preferably a stepping solenoid valve, is installed on the main pipe 1. The valve 3 is located between the inlet and outlet of the branch pipe 2. The valve 3 is electrically connected to the ultrasonic flow meter 5. The identification code of the ultrasonic flow meter 5 can be used as a network address code. The corresponding command set is used as a communication protocol. The opening degree of the stepping solenoid valve is controlled by the current loop and its OCT output. When the water flow in the main pipe 1 is small, the ultrasonic flow meter 5 controls the opening degree of the valve 3 to decrease to ensure that the water flow can be diverted to the inside of the branch pipe 2. When the water flow in the main pipe 1 is large, the ultrasonic flow meter 5 controls the opening degree of the valve 3 to increase to ensure the smooth flow of water.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
