Description

Technical Field

[0001] The present application relates to the technical field of flow velocity detection, and in particular to a flow meter detection device. Background Art

[0002] The importance of water resources is self-evident. It is the foundation for the existence and reproduction of life on Earth and has a crucial impact on natural ecosystems, human socio-economic development, and human health. Water resources play an irreplaceable role in maintaining ecological balance, promoting economic development, safeguarding human health, and social stability. Accurately measuring water flow velocity is crucial for understanding the flow characteristics of water bodies, assessing water resource status, and formulating effective water resource management strategies. Traditional flow velocity measurement methods include buoys and mechanical rotor flowmeters, but these methods suffer from limited measurement accuracy, susceptibility to environmental influences, and complex operation.

[0003] The existing technology still has the following problems:

[0004] 1. The existing flow meter detection device cannot simulate flow velocity measurement, which requires real-time measurement at multiple locations, making it difficult to grasp the large flow velocity of the river. In addition, it is impossible to collect the content of impurities in the water flow. In the water resource assessment, other instruments are needed for detection, so the evaluation effect of the flow meter detection device is limited.

[0005] 2. Existing flowmeters cannot quickly adjust the water flow height difference to meet actual conditions. This necessitates data collection at multiple locations. This complicates data collection in scenarios requiring local, short-term measurements, such as reservoirs and sluice gates. However, under certain conditions, such as extremely low water velocity or obstacles in the ultrasonic signal propagation path, excessive external interference can lead to inaccurate measurement data.

[0006] 3. The existing flow meter detection device requires measurement to know the water level height at the measurement point, which makes it difficult to control the flow rate of the water at a specific height, making it difficult to accurately control the height difference of the water level of the detection device, and it is difficult to detect changes in the water level in time, resulting in errors in the detection data.

A screen 11 is provided on the outer surface of the inner cavity of the second water pipe 10. The screen 11 is used to dissipate the kinetic energy of the water. A water pump is provided in the inner cavity of the water reservoir 2. The end of the second water pipe 10 away from the water tank 6 is connected to the first water tank 3. A rectangular weir is provided on the side of the second water tank 4 away from the partition assembly 8. The rectangular weir is connected to the water reservoir 2. The middle part of the screen 11 is a honeycomb structure and is located in the second water pipe 1 0 cavity. This detection device is a simulation device that is convenient for collecting water flow in scenarios requiring local, short-term measurements, such as water flow in reservoirs and sluices. It is usually used to collect water in water areas where flow rate detection is required. Water is injected into the cavity of the water reservoir 2 and transported to the cavity of the water tank 6 by a water pump. The water in the water tank 6 flows into the cavity of the first water tank 3 through the second water pipe 10. The first water tank 3 flows into the cavity of the second water tank 4 through the baffle assembly 8. The second water tank 4 flows into the cavity of the water reservoir 2 through the rectangular weir to form a water cycle. The baffle assembly 8 forms a height difference between the first water tank 3 and the second water tank 4, thereby measuring the water flow velocity. The filter assembly 7 is used to filter impurities in the collected water sample for measuring the impurity content and facilitating water quality analysis. The baffle assembly 8 can control the water level difference. A corresponding flow rate measuring instrument is placed in the cavity of the second water tank 4 to facilitate simulation of water flow velocity under different height differences. The water level assembly 9 is used to quickly obtain the water levels in the cavities of the first water tank 3 and the second water tank 4, and can promptly issue an alarm when the water level exceeds the set value.

[0040] See also Figure 2 As shown, the filter assembly 7 includes a slide plate 71, which is slidably connected to the water tank 6. The inner cavity of the slide plate 71 is slidably connected to a buffer mechanism 72. The bottom end of the buffer mechanism 72 is fixedly connected to a conduit 73. The outer surface of the conduit 73 is sleeved with a connecting clip 74. The bottom end of the connecting clip 74 is provided with a collecting box 75. A filter mechanism 76 is provided below the conduit 73. The slide plate 71 is moved to place the buffer mechanism 72 below the first water pipe 5, so that water falls from the inner cavity of the conduit 73 through the conduit 73 into the water tank 6. The filter mechanism 76 is used to filter the water. The connecting clip 74 and the collecting box 75 are plug-in connected and are used to place impurities collected by the filter mechanism 76. At the same time, when there is no need to filter the water, the slide plate 71 is moved to make the water in the first water pipe 5 fall directly into the inner cavity of the water tank 6 without passing through the filter assembly 7.

[0041] See also Figure 2and Figure 3 As shown, the buffer mechanism 72 includes a collecting bucket 721, a fixing plate 722 is fixedly installed on the outer surface of the lower end of the collecting bucket 721, a conduit 73 is sleeved on the bottom end of the collecting bucket 721, an insertion rod 723 is fixedly installed on the lower surface of the fixing plate 722, and a first spring 724 is sleeved on the outer surface of the insertion rod 723.

The first spring 724 is located between the fixing plate 722 and the slide 71. When water in the first water pipe 5 falls into the collecting bucket 721, the fixing plate 722 is driven to move downward, thereby driving the first spring 724 to compress, causing the insertion rod 723 to swing in the inner cavity of the slide 71, thereby reducing the impact force of the water flow and preventing the water flow from splashing.

[0042] See also Figure 2 、 Figure 4 and Figure 5As shown, the filter mechanism 76 includes a connecting cylinder 761, which is fixedly connected to the conduit 73.

The water flow passing through the inner cavity of the guide tube 73 is filtered by the filter screen cylinder 762, so that impurities remain at the bottom end of the filter screen cylinder 762. After the water circulation is completed, the filter screen cylinder 762 is disassembled in the connecting cylinder 761, and the sliding plate 71 is moved to make the water in the first water pipe 5 fall directly into the water tank 6. The second spring 768 is compressed by pulling the movable ring 767. At this time, the movable ring 767 and the card slot 7611 are disengaged, and the first threaded rod 764 is rotated to drive the limiting ring 766 to slide on the first The inner cavity of the groove 765 moves, so that the limit ring 766 is disengaged from the receiving groove 7610. At this time, the filter mesh cylinder 762 can be taken out from the inner cavity of the connecting cylinder 761, and the impurities in the inner cavity of the filter mesh cylinder 762 are placed in the collection box 75 for collection. When the impurities need to be used, the collection box 75 is pulled out from the connecting card strip 74 for subsequent use. By measuring the flow rate of water to collect impurities, it is possible to analyze whether the flow rate changes under the influence of impurities and detect the content of impurities in the water, which is convenient for evaluating the flow characteristics of the water body, assessing the water resource status and formulating effective water resource management.

The connecting bar 87 and the connecting block 89 are rotatably connected, and the second threaded rod 84 is rotatably connected to the first water tank 3 and the second water tank 4. The partition block 81 is partially hollowed out, and the hollowed out part is blocked by the movable plate 82. The flow hole 83 is used to form a height difference for the circulation of water in the first water tank 3 and the second water tank 4. The water flow under different conditions is simulated by changing the height of the flow hole 83. The rotation of the hand lever 85 drives the second threaded rod 84 to rotate, and the rotation of the second threaded rod 84 drives the adjusting block 86 to move on the second threaded rod 84. The movement of the adjusting block 86 drives the connecting bar 87 to rotate on the adjusting block 86. The rotation of the adjusting block 86 drives the height of the connecting block 89 to change. The change in the height of the connecting block 89 drives the height of the connecting plate 88 to change. The change in the height of the connecting plate 88 drives the height of the movable plate 82 to change. The change in the height of the movable plate 82 drives the flow hole 83 to move up and down in the inner cavity of the partition block 81, so that the movable plate 82 slides up and down on the partition block 81. The water flow height difference describes the height change of the water flow in the vertical direction, and can also be understood as the height change per unit length. When the liquid flows from a higher point to a lower point through the pipe, this height difference will accelerate the water flow. The essence of the siphon phenomenon is to use the force of the liquid level height difference. Through this change in height difference, the flow rate of different waters can be better simulated and the interference of external weather and environment can be avoided.

The height of the protrusion 986 can be adjusted by moving the movable piece 981 on the water level cylinder 91. At this time, the protrusion 986 squeezes the third spring 987 to move the slide bar 984 outward. The movement of the slide bar 984 drives the pressure ring 985 to move. The movement of the pressure ring 985 drives the pressure ring 985 to squeeze the button 983. After the button 983 is squeezed, it drives the alarm 96 to sound an alarm, thereby reminding the staff to correct the water level, improve the precision of controlling the height difference of the water level of the detection device, and avoid errors in the detection data.

[0046] In summary, this detection device is an analog device, which is convenient for collecting scenes that require local and short-term measurements, such as water flow in reservoirs, sluices, etc. It usually collects water in water areas where flow rate detection is required at fixed points, injects water into the inner cavity of the water reservoir 2, and transports water to the inner cavity of the water tank 6 through a water pump. The water in the water tank 6 flows into the inner cavity of the first water tank 3 through the second water pipe 10, and the first water tank 3 flows into the inner cavity of the second water tank 4 through the partition assembly 8. The second water tank 4 flows into the inner cavity of the water reservoir 2 through the rectangular weir to form a water cycle, and a height difference is formed between the first water tank 3 and the second water tank 4 by the partition assembly 8, so as to measure the water flow rate. The filter assembly 7 is used to filter impurities in the collected water sample and is used to measure the impurity content, which is convenient for analyzing the water quality. Component 8 can control the water level difference. A corresponding flow rate measuring instrument is placed in the inner cavity of the second water tank 4 to simulate the water flow rate under different height differences. The water level component 9 is used to quickly obtain the water level in the inner cavity of the first water tank 3 and the second water tank 4. At the same time, an alarm can be issued in time when the water level exceeds the set value. The sliding plate 71 is moved to place the buffer mechanism 72 below the first water pipe 5, so that the water falls from the inner cavity of the conduit 73 through the conduit 73 into the water tank 6. The filtering mechanism 76 is used to filter the water. The connecting strip 74 and the collecting box 75 are plugged in and out for placing impurities collected by the filtering mechanism 76. At the same time, when the water does not need to be filtered, the sliding plate 71 is moved to make the water in the first water pipe 5 fall directly into the inner cavity of the water tank 6 without passing through the filtering component 7. The water flow rate under different conditions is simulated by changing the height of the flow hole 83, that is, rotating the hand lever 85 drives the second threaded rod 84 to rotate, the rotation of the second threaded rod 84 drives the adjustment block 86 to move on the second threaded rod 84, the movement of the adjustment block 86 drives the connecting bar 87 to rotate on the adjustment block 86, the rotation of the adjustment block 86 drives the height of the connecting block 89 to change, the change in the height of the connecting block 89 drives the height of the connecting plate 88 to change, the change in the height of the connecting plate 88 drives the height of the moving plate 82 to change, the change in the height of the moving plate 82 drives the flow hole 83 to move up and down in the inner cavity of the partition block 81, so that the moving plate 82 slides up and down on the partition block 81, and the water height difference is a description of the water flow. The height change in the vertical direction can better simulate the flow rate of different water areas through this change in height difference, and avoid interference from external weather and environment. The water level component 9 is used to measure the liquid level in the first water tank 3 and the second water tank 4. The water flows into the inner cavity of the water level cylinder 91 from the water inlet 92, causing the float 94 to float and rise. The rise of the float 94 drives the measuring ruler 93 to move in the inner cavity of the water level cylinder 91, causing the pointer 95 to point to the data on the measuring ruler 93 to change, which is convenient for quickly measuring the height of the liquid level. An alarm liquid level can be set by the alarm mechanism 98 and the moving mechanism 99, so that when changes occur, the pressure plate 97 can pass through the alarm mechanism 98 to make the alarm 96 sound an alarm, providing measurement personnel with water level correction.
