Description

Background Art

During the exploitation and utilization of geothermal water, due to water demand or poor installation position of the flow meter sensor, the liquid in the measuring tube cannot be filled, and a small amount of gas flows in the water pipe in a stratified flow or wavy flow. The fault phenomenon is manifested as an increase in error, that is, the flow measurement value does not match the actual value; if the flow is a bubble flow or a plug flow, in addition to the measurement value not matching the actual value, the output will also appear due to the gas phase momentarily covering the electrode surface. Shaking; if the gas phase part of the flow cross-sectional area in the stratified flow of the horizontal pipeline increases, that is, the degree of liquid underfilling the tube increases, output shaking will also occur. If the liquid underfilling the tube is serious, so that the liquid level is below the electrode, the output will appear overfull. Therefore, a flow measurement device that can be used under different working conditions is proposed to solve the above problems.

Specifically, the geothermal water pipe 1 is a pipe for transmitting geothermal water, which is usually used in heat transfer systems from geothermal sources to buildings. The geothermal wellhead device 7 is used to connect the underground geothermal energy with the pipeline on the surface. The flange 6 is used to connect the two parts of the pipeline, fix them together by bolts, and allow easy disassembly and maintenance. The flow meter 5 is used to measure the flow rate of the fluid in the pipeline, which is very important for monitoring and adjusting the operation of the system. The steel pipe reducer 4 may be a part of the pipeline system used to connect pipelines of different diameters to ensure a smooth transition of the fluid. The butterfly valve 3 is a valve used to adjust the flow rate of the pipeline. The amount of fluid passing through is adjusted by changing the degree of opening and closing of the valve. The exhaust valve 2 is used to discharge air in the pipeline system to ensure that there are no bubbles that hinder the flow of fluid when the system is running.

Referring to Figures 2-3, each of the two groups of installation components includes two installation frames 11, and the multiple installation frames 11 are fixedly connected to the outer periphery of the flow meter 5. The upper and lower ends of the two installation frames 11 are fixedly connected with installation shafts 10, and the tops of the multiple installation frames 11 are fixedly connected with a protective block 8, and the top of the protective block 8 is slidably connected with an observation plate 9. The disassembly component includes a spring 14, the spring 14 is fixedly connected inside the protective block 8, one end of the spring 14 is fixedly connected with an L-shaped block 15, and the end of the L-shaped block 15 away from the spring 14 is fixedly connected with a connecting rod 13, a slide groove 17 is opened inside the right side of the observation plate 9, and the connecting rod 13 is slidably connected inside the slide groove 17, a slot 16 is opened inside the protective block 8, and the L-shaped block 15 is slidably connected inside the slot 16, and the end of the connecting rod 13 away from the L-shaped block 15 is fixedly connected with a pull rod 12.

Specifically, the mounting frame 11 provides a structure for supporting and installing components of the pipeline system to ensure the stability of the system. The mounting shaft 10 is a shaft used to support and fix some components so that they can rotate or move freely. The protective block 8 is used to protect some key parts in the pipeline system to prevent external impact or damage. The observation plate 9 provides a window for checking the internal condition of the pipeline to facilitate inspection and maintenance. The spring 14 is used to provide elastic support. The L-shaped block 15 is a special design for fixing or connecting components in an "L" shape. The connecting rod 13 is used to connect the pull rod 12 and the L-shaped block 15 so that they can transmit motion to each other. The pull rod 12 is used to transmit motion. The slot 16 is a slot-shaped structure used to fix or adjust the position of the L-shaped block 15. The slide groove 17 provides a structure that allows components to slide relative to each other, which is usually used to adjust the position of the connecting rod 13 or to achieve specific motion.

Working principle: Place one end of the geothermal water pipe 1 into the wellhead device 7 of the geothermal well, and detect the flow rate by secretly rotating a flow meter 5 in the middle of the geothermal water pipe 1. Reserve a distance of ten times the pipe diameter at the front end of the flow meter 5 and a distance of five times the pipe diameter at the rear end to ensure the stability of the fluid state and the measurement environment.

Push the pull rod 12, compress the spring 14 through the connecting rod 13, and the L-shaped block 15 moves in the direction of the spring 14. When the bottom of the observation plate 9 fits the top of the protection block 8, put the L-shaped block 15 into the slot 16, release the pull rod 12, and the spring 14 resets. The installation of the observation plate 9 is completed. While protecting the flow meter 5, the device can observe the flow meter 5 through the observation plate 9.
