[0002] During the exploitation of natural gas such as shale gas, gas-liquid two-phase flow appears. After exploitation, it is necessary to measure the two-phase flow. Using a two-phase flowmeter for measurement is a way to save exploitation measurement costs, reduce land use and save labor costs.

[0003] When gas-liquid two-phase flow is flowing, gas and liquid are easy to mix, so it is inconvenient to detect liquid and gas, and the measurement is rather cumbersome. Therefore, a gas-liquid two-phase flow metering device is provided. Summary of the Utility Model

A transparent plate is installed on the inner wall of the storage tank, and a scale is engraved on the outer wall of the transparent plate. Two guide rods are fixedly installed on the inner bottom wall of the storage tank. A floating wood is slidably installed on the outer walls of the two guide rods. A water level sensor is installed at the lower end of the floating wood. A vertical movement mechanism is arranged on the outer wall of the storage tank. A camera is arranged inside the vertical movement mechanism. The horizontal position of the camera corresponds to the horizontal position of the water level sensor. A gas-liquid two-phase flow mechanism is arranged outside the storage tank.

[0006] By adopting the above technical solution, through the design of the transparent plate and the scale, the staff can intuitively observe the liquid level change in the storage tank. Combined with the water level sensor on the floating wood, the liquid level data can be obtained in real time and accurately, so as to realize the accurate measurement of gas-liquid two-phase flow. The camera arranged inside the vertical movement mechanism, its horizontal position corresponds to the water level sensor. Through the real-time shooting of the camera, the liquid level change can be remotely monitored and compared with the data of the water level sensor to ensure the accuracy and reliability of the data. This intelligent monitoring method not only improves the work efficiency, but also reduces the error of manual operation. The sliding installation design of the guide rod and the floating wood enables the floating wood to freely rise and fall with the change of the liquid level, so as to realize the dynamic monitoring of the flow under different liquid level conditions. This design improves the adaptability and flexibility of the device, enabling it to be widely used in various gas-liquid two-phase flow scenarios, and the camera can record the height difference between the liquid and the gas according to the scale, so as to calculate the flow of the liquid and the gas.

[0010] By adopting the above technical solution, the liquid pipeline can play a role in connecting the storage tank and the tee joint.

[0014] By adopting the above technical solution, since both ends of the T-shaped channel are tapered, when the liquid pipeline drains water, the pressure will be reduced and the speed will increase, flowing through at an extremely high speed, thus having the ability to suck. Therefore, the gas at a position where the water level in the storage tank is lower than the connecting pipe can be sucked in through the connecting pipe, and the steam-water mixture can be discharged through the drain pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Please refer to Figures 1-4, the present utility model provides a technical solution: a novel gas-liquid two-phase flow metering device, which includes a storage tank 1. A transparent plate 2 is installed on the inner wall of the storage tank 1, and a scale is engraved on the outer wall of the transparent plate 2. Two guide rods 9 are fixedly installed on the inner bottom wall of the storage tank 1. A floating wood 8 is slidably installed on the outer walls of the two guide rods 9. A water level sensor 10 is installed at the lower end of the floating wood 8. A vertical movement mechanism is arranged on the outer wall of the storage tank 1. A camera 6 is arranged inside the vertical movement mechanism. The horizontal position of the camera 6 corresponds to the horizontal position of the water level sensor 10. A gas-liquid two-phase flow mechanism is arranged outside the storage tank 1. The movement mechanism includes a motor 3. The motor 3 is installed on the outer wall above the storage tank 1. The output shaft of the motor 3 is fixedly connected with a reciprocating lead screw 4. The lower end of the reciprocating lead screw 4 is rotatably installed with a fixed block 7. The fixed block 7 is fixedly installed with the storage tank 1. The reciprocating lead screw 4 is threadedly installed with a threaded block 5.

[0028] In the technical solution of the present utility model, through the design of the transparent plate 2 and the scale, the staff can intuitively observe the liquid level change in the storage tank 1. Combining with the water level sensor 10 on the floating wood 8, the liquid level data can be obtained in real time and accurately, so as to realize the accurate measurement of the gas-liquid two-phase flow. The camera 6 arranged inside the vertical movement mechanism, its horizontal position corresponds to the water level sensor 10. Through the real-time shooting of the camera 6, the liquid level change can be remotely monitored and compared with the data of the water level sensor 10 to ensure the accuracy and reliability of the data. This intelligent monitoring method not only improves the work efficiency but also reduces the error of manual operation. The sliding installation design of the guide rods 9 and the floating wood 8 enables the floating wood 8 to freely rise and fall with the change of the liquid level, so as to realize the dynamic monitoring of the flow under different liquid level conditions. This design improves the adaptability and flexibility of the device, enabling it to be widely applied to various gas-liquid two-phase flow scenarios. And the camera 6 can record the height difference between the liquid and the gas according to the scale, so as to calculate the flow of the liquid and the gas.

[0029] In addition, the storage tank 1 can play a role in fixing the motor 3, and the motor 3 can drive the reciprocating lead screw 4 to rotate, so that the reciprocating lead screw 4 drives the threaded block 5 to move vertically.

[0030] In the technical solution of the present utility model, such as Figure 1 , Figure 2 and Figure 4As shown, a connecting pipe 13 is installed on the side of the storage tank 1 away from the camera 6, and a three-way head 14 is installed on the side of the connecting pipe 13 away from the storage tank 1. The storage tank 1 can play a role in fixing the connecting pipe 13, and the connecting pipe 13 can play a role in installing the three-way head 14. The gas-liquid two-phase flow mechanism includes a liquid pipeline 12, which is installed at the lower end of the middle part of the storage tank 1. The side of the liquid pipeline 12 away from the storage tank 1 is fixedly installed with the side end of the three-way head 14. The liquid pipeline 12 can play a role in connecting the storage tank 1 and the three-way head 14. A discharge pipe 15 is installed on the side of the three-way head 14 away from the liquid pipeline 12. The liquid and gas provided inside the three-way head 14 can be discharged through the discharge pipe 15. An inverted T-shaped channel 17 is opened inside the three-way head 14. The two ends of the T-shaped channel 17 are tapered, and the large conical openings at both ends of the T-shaped channel 17 are arranged on the outer wall of the three-way head 14. Since the two ends of the T-shaped channel 17 are tapered, when the liquid pipeline 12 drains water, the pressure will be reduced and the speed will increase, flowing through at an extremely high speed, thus having the ability to suck. Therefore, the gas at a position where the water level in the storage tank 1 is lower than the connecting pipe 13 can be sucked in through the connecting pipe 13, and the steam-water mixture can be discharged through the drain pipe. An air extraction pipeline 11 is installed on the outer wall of the storage tank 1 above the connecting pipe 13. Solenoid valves 16 are respectively installed inside the air extraction pipeline 11, the liquid pipeline 12, the connecting pipe 13 and the discharge pipe 15. The solenoid valves 16 can play a role in closing and opening the air extraction pipeline 11, the liquid pipeline 12, the connecting pipe 13 and the discharge pipe 15.

[0031] During use, first, both ends of the T-shaped channel 17 are tapered. Thus, when the liquid pipeline 12 drains water, the pressure will be reduced and the speed will increase, flowing through at an extremely high speed, thereby having the ability to suck. As a result, the gas below the position of the connecting pipe 13 in the storage tank 1 can be sucked in through the connecting pipe 13, and the steam-water mixture can be discharged through the drain pipe. With the design of the transparent plate 2 and the scale, the staff can visually observe the liquid level change in the storage tank 1. Combined with the water level sensor 10 on the floating log 8, the liquid level data can be obtained in real time and accurately, thereby realizing the precise measurement of the gas-liquid two-phase flow. The camera 6 installed inside the vertical moving mechanism has its horizontal position corresponding to that of the water level sensor 10. Through the real-time shooting of the camera 6, the liquid level change can be remotely monitored and compared with the data of the water level sensor 10 to ensure the accuracy and reliability of the data. This intelligent monitoring method not only improves work efficiency but also reduces the error of manual operation. The sliding installation design of the guide rod 9 and the floating log 8 enables the floating log 8 to freely rise and fall with the change of the liquid level, thereby realizing the dynamic monitoring of the flow rate under different liquid level conditions. This design improves the adaptability and flexibility of the device, enabling it to be widely applied to various gas-liquid two-phase flow scenarios. Moreover, the camera 6 can record the height difference between the liquid and the gas according to the scale, thereby calculating the flow rates of the liquid and the gas. The entire device is made of high-strength and corrosion-resistant materials, having good durability and stability. At the same time, all functional components have undergone strict quality control and testing to ensure that the device can maintain stable performance and reliable working conditions during long-term operation.
