Description

Technical Field

[0001] This utility model relates to the field of triangular weir metering technology, specifically a pipeline discharge structure suitable for triangular weir metering. Background Technology

[0002] In industrial production, agricultural irrigation, and municipal drainage, flow measurement is a core component for achieving rational water resource allocation, process parameter monitoring, and compliant discharge management. The triangular weir method is a common technical solution in traditional flow measurement scenarios. However, its practical application is highly dependent on hardware conditions, requiring strict constraints such as specific slopes and precise alignment with the flow direction to ensure flow stability. This limits its use in complex terrains and areas with limited spatial variation. Furthermore, the triangular weir method necessitates the construction of specialized structures such as weir channels and water level observation platforms, making its implementation prohibitively expensive in cost-sensitive scenarios. Additionally, because it relies on a fixed conversion relationship between water level and flow rate, external interference such as blockages and flow fluctuations can lead to inaccurate measurement units, making it inconvenient and prone to measurement errors. Utility Model Content

[0003] The purpose of this utility model is to provide a pipeline discharge structure suitable for triangular weir metering, so as to solve the problems of inconvenient installation, high installation cost and inaccurate measurement of the triangular weir metering method mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipeline discharge structure suitable for triangular weir metering, comprising an input pipeline, one end of which is fixed to the outer surface of a channel, and a buffer pool is provided on the ground on the side of the input pipeline away from the channel. The input pipeline is inclined between the buffer pool and the channel. One end of the input pipeline is inserted into the buffer pool. A water outlet pipe is installed through the side surface of the buffer pool, and a first bend is inserted and pasted at one end of the water outlet pipe. A second bend is inserted and pasted at one end of the first bend. A T-shaped tee is fixedly pasted on the side of the second bend away from the buffer pool, and a sensor housing is fixedly pasted on one side of the T-shaped tee. A discharge terminal is fixedly pasted on the end of the sensor housing away from the first bend.

[0005] Preferably, an intelligent flow stabilizing valve is installed between the input pipes, and both ends of the input pipes are fixedly connected to the channel and the buffer pool, respectively. The buffer pool is provided with a weir crest at the end near the outlet pipe, and the height of the weir crest exceeds the discharge terminal.

[0006] By adopting the above technical solution, the water in the channel can be discharged into the buffer pool through the input pipe by using an intelligent flow stabilizing valve, so that the water flow rate discharged from the input pipe can be stabilized at the required rated value. At the same time, the design of the weir crest height can allow the buffer pool to discharge in one direction when it is severely overloaded.

[0007] Preferably, an air tube is threaded onto the side of the T-shaped three-way pipe away from the second bend and the sensor housing, and the air tube is tightly fitted to the outer surface of the T-shaped three-way pipe. The air tube is a tubular body made of transparent material, and the diameter of the air tube is smaller than the diameter of the water outlet pipe.

[0008] By adopting the above technical solution, the water level and flow rate can be directly observed through the transparent material of the air tube. The air tube can also be used to discharge and create eddies in the pipeline, ensuring the stability of the pipeline discharge structure during measurement and reducing the impact of gas on the measurement values.

[0009] Preferably, a water level clamp is attached to the outer surface of the air tube, and a screw is provided on the outer surface of the water level clamp. The outer surface of the water level clamp is in close contact with the air tube. Indicator needles are fixedly provided on both sides of the water level clamp, and the outer surface of the indicator needles is in contact with the outer surface of the air tube. The water level clamp and indicator needles are at the same height as the discharge terminal.

[0010] By adopting the above technical solution, the water level line clip can be easily installed and fixed, and the water level line inside the air tube can be directly observed through the use of the indicator needle, providing an intuitive indicator standard for the air tube and greatly improving the convenience of installation and use.

[0011] Preferably, a filter screen is threadedly installed on the side of the buffer pool near the outlet pipe, and the filter screen is cylindrical in design, and the filter screen and the outlet pipe are concentrically designed.

[0012] By adopting the above technical solution, the cylindrical design of the filter screen can effectively prevent impurities discharged into the buffer pool from being discharged through the outlet pipe and causing blockage of subsequent pipes, while increasing the effective area of ​​the filter screen, improving the convenience of use, and making it easy to replace the filter screen.

[0013] Preferably, an ultrasonic meter is threadedly mounted on the outer surface of the sensor housing, and a protective box is threadedly mounted on the outer surface of the ultrasonic meter. A wireless data switch is fixedly installed inside the protective box, and the wireless data switch is connected to the intelligent flow stabilizing valve and the ultrasonic meter respectively.

[0014] By adopting the above technical solution, the internal electronic components can be protected by the use of a protective box, reducing damage caused by water splashing from the discharge terminal. At the same time, the water flow velocity passing through the sensor housing can be monitored by an ultrasonic meter, and the data detected by the ultrasonic meter can be transmitted to the user terminal through a wireless data exchange, improving the convenience of use and enabling remote real-time measurement data.

[0015] Preferably, a charge / discharge battery pack is fixedly installed inside the protective box at one end near the input pipe, and a pipe generator is fixedly installed on the outer surface of the input pipe, and the pipe generator is connected to the charge / discharge battery pack.

[0016] Using the above technical solution, the difference in height between the water discharged from the input pipe and the buffer pool can drive the pipeline generator to rotate and generate electricity through the water flow. The electricity is stored in a rechargeable battery pack and used by the intelligent flow stabilizing valve, ultrasonic meter, and wireless data exchange, so that it can continue to be used even in the event of an unexpected power outage, reducing energy consumption during use.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the pipeline discharge structure suitable for triangular weir metering is as follows:

[0018] 1. By constructing a buffer pool, water in the channel can be quantitatively discharged and sent into the buffer pool through the input pipe and the use of an intelligent flow stabilizing valve. This ensures that the water flow can enter the buffer pool in a quantitative manner, reducing the impact caused by unstable water flow. The pasting and fixing of the outlet pipe, first bend pipe, second bend pipe, T-shaped tee pipe, sensor housing, and discharge terminal make it easy and convenient to set up the pipeline discharge structure, improving the convenience and stability of the installation, and reducing the cost and site requirements.

[0019] 2. During use, the air pipe, which is threaded onto the outer surface of the T-shaped tee, allows for effective and intuitive viewing of the water level between the buffer tank, the outlet pipe, and the discharge terminal. The water level clamp can be easily fixed onto the outer surface of the air pipe, and its height can be easily adjusted. The highest and lowest water levels can be clearly seen using the indicator needle, allowing users to view the water level intuitively and accurately.

[0020] 3. When in use, impurities in the buffer pool can be filtered through the filter screen, and the water flow discharged through the input pipe can drive the pipeline generator to generate electricity. The height difference between the input pipe and the buffer pool increases the power generation, and the generated current can be stored in the rechargeable battery pack for continuous use, achieving self-sufficiency and reducing the need for external power supply. At the same time, the water flow rate through the sensor housing can be monitored by an ultrasonic meter, and the real-time data is transmitted to the user terminal through a wireless data exchange, allowing the user to remotely monitor the water volume through the pipeline discharge structure.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6This utility model provides a technical solution: a pipeline discharge structure suitable for triangular weir metering, including an input pipeline 1, one end of which is fixed to the outer surface of a channel, and a buffer pool 3 is provided on the ground on the side of the input pipeline 1 away from the channel. The input pipeline 1 is inclined between the buffer pool 3 and the channel. One end of the input pipeline 1 is inserted into the buffer pool 3. A water outlet pipe 4 is installed through the side surface of the buffer pool 3, and a first bend pipe 5 is inserted and pasted at one end of the water outlet pipe 4. A second bend pipe 6 is inserted and pasted at one end of the first bend pipe 5. A T-shaped tee pipe 7 is fixedly pasted on the side of the second bend pipe 6 away from the buffer pool 3, and a sensor housing 9 is fixedly pasted on one side of the T-shaped tee pipe 7. A discharge terminal 11 is fixedly pasted on the end of the sensor housing 9 away from the first bend pipe 5.

[0030] Firstly, during use, the water in the channel will enter the buffer tank 3 through the input pipe 1, and be controlled by the intelligent flow stabilizing valve 2 so that the water flow rate discharged into the buffer tank 3 can be stabilized within the approved value. This ensures the stability of the amount of water discharged from the outlet pipe 4, the first bend pipe 5, the second bend pipe 6, the T-shaped tee pipe 7, the sensor housing 9, and the discharge terminal 11, greatly improving the stability of the discharge flow rate of the pipeline discharge structure.

[0031] During construction, it is only necessary to construct a buffer pool 3 with dimensions of 80*120*50cm using concrete, and to build the outlet pipe 4 20cm below the water level. Then, the outlet pipe 4, the first bend pipe 5, the second bend pipe 6, the T-shaped tee pipe 7, the sensor housing 9, and the discharge terminal 11 are bonded and fixed together to quickly install and manufacture the pipeline discharge structure.

[0032] A smart flow stabilizing valve 2 is installed between the input pipes 1 and the input pipes 1. The two ends of the input pipes 1 are fixedly connected to the channel and the buffer pool 3 respectively. A weir crest 13 is set at the end of the buffer pool 3 near the outlet pipe 4. The height of the weir crest 13 exceeds the discharge terminal 11. A filter screen 14 is threadedly installed on the side of the buffer pool 3 near the outlet pipe 4. The filter screen 14 is cylindrical and concentric with the outlet pipe 4.

[0033] Secondly, after the water is discharged into the buffer pool 3, the filter screen 14 will filter the water, so that impurities in the water will not be discharged from the outlet pipe 4 and cause blockage of the subsequent pipes. At the same time, the construction of the weir top 13 can effectively improve the range of the verification values ​​during testing, greatly reduce the probability of the pipeline discharge structure being blocked and unusable, and improve the range of the verification values ​​during testing.

[0034] An air pipe 8 is threaded onto the side of the T-shaped three-way pipe 7 away from the second bend pipe 6 and the sensor housing 9, and the air pipe 8 is tightly fitted to the outer surface of the T-shaped three-way pipe 7. The air pipe 8 is a tubular body made of transparent material, and the diameter of the air pipe 8 is smaller than the diameter of the water outlet pipe 4. A water level clamp 12 is fitted to the outer surface of the air pipe 8, and a screw is provided on the outer surface of the water level clamp 12. The outer surface of the water level clamp 12 is tightly fitted to the air pipe 8. Indicator needles 15 are fixedly installed on both sides of the water level clamp 12, and the outer surface of the indicator needles 15 is fitted to the outer surface of the air pipe 8. The water level clamp 12 and the indicator needles 15 are at the same height as the discharge terminal 11.

[0035] Furthermore, the water level inside the outlet pipe 4, first bend pipe 5, second bend pipe 6, T-shaped tee pipe 7, sensor housing 9, and discharge terminal 11 can be easily observed through the installed transparent air pipe 8. With the use of water level line card 12 and the indication of indicator needle 15, staff can effectively grasp the water level inside the pipeline discharge structure when they come to check, greatly improving the convenience of use.

[0036] An ultrasonic meter 10 is threaded onto the outer surface of the sensor housing 9, and a protective box 17 is threaded onto the outer surface of the ultrasonic meter 10. A wireless data switch 19 is fixedly installed inside the protective box 17. The wireless data switch 19 is connected to the intelligent flow stabilizing valve 2 and the ultrasonic meter 10. A rechargeable battery pack 18 is fixedly installed at one end of the protective box 17 near the input pipe 1. A pipe generator 16 is fixedly installed on the outer surface of the input pipe 1 and is connected to the rechargeable battery pack 18.

[0037] Furthermore, the ultrasonic meter 10 can monitor the water flow through the sensor housing 9 in real time, and transmit the measured data to the wireless data exchange 19 and send it to the user terminal. This allows staff to remotely and in real time know the flow rate of water discharged from the pipeline discharge structure. At the same time, the pipeline generator 16 can generate electricity in real time by inputting the water discharged from the pipeline 1 and the height difference. The generated electricity can be stored in the rechargeable battery pack 18. The protective box 17 protects the rechargeable battery pack 18 and the wireless data exchange 19, allowing the pipeline discharge structure to continue to work for a period of time when the power is off. This greatly improves the stability during use and allows for real-time monitoring of the measured data.

[0038] Working principle: During use, water in the channel enters the input pipe 1 through the water flow channel and is discharged into the buffer tank 3 by the intelligent flow stabilizing valve 2 to maintain the water volume in the buffer tank 3 within a certain range. The water in the buffer tank 3 is then filtered through the filter screen 14 and discharged from the outlet pipe 4. The water then passes through the first bend pipe 5, the second bend pipe 6, the T-shaped tee pipe 7, and the sensor housing 9 before finally being discharged from the discharge terminal 11. During the water flow, air mixed in with the water can be discharged through the air pipe 8. The air pipe 8, in conjunction with the water level gauge 12 and the indicator needle 15, facilitates the discharge through the pipeline. The structure utilizes the principle of communicating vessels, allowing for a direct view of the water level in the buffer pool 3 and inside the pipe, facilitating observation. Simultaneously, the water discharged from the input pipe 1 accelerates through the height difference, driving the pipe generator 16 to generate electricity, which can be stored in the rechargeable battery pack 18 for self-sufficiency and use during power outages. Furthermore, the ultrasonic meter 10 monitors the water flow through the sensor housing 9 and transmits real-time data to the user terminal via the wireless data exchange 19, enabling users to remotely and in real-time access to the flow data discharged from the pipe discharge structure, significantly improving the convenience of its use and installation.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
