Description

Technical Field

[0001] This utility model relates to the field of water flow velocity measurement technology, and in particular to a water flow velocity measurement device for water conservancy monitoring. Background Technology

[0002] The measurement of fluid velocity is of great significance for studying the motion law of fluids and the interaction mechanism between particles inside the fluid. A flow meter is an instrument for measuring the flow velocity of water bodies such as rivers, lakes and canals. Currently, there are four main types: mechanical, kinetic energy conversion, electrical and ultrasonic. They are further divided into propeller flow meters, Pitot tube average point flow meters, electromagnetic flow meters and ultrasonic flow meters.

[0003] In the prior art, Chinese Patent Publication No. CN218240080U discloses a safe water flow velocity measuring device. The safe water flow velocity measuring device includes a base; a bracket fixedly installed on the top of the base; a crossbar fixedly installed on one side of the bracket; a first threaded rod rotatably installed on the bracket; a sliding seat threadedly installed on the first threaded rod; a detection mechanism disposed on the sliding seat; four support leg mechanisms symmetrically arranged on both sides of the base; and a second motor disposed on one side of the bracket, with the output shaft of the second motor fixedly connected to one end of the first threaded rod. The safe water flow velocity measuring device provided by this utility model has the advantages of being able to detect water flow at different positions through electric adjustment, requiring less effort, and offering higher safety.

[0004] However, existing water flow velocity measuring devices for water conservancy monitoring involve installing the flow velocity meter inside the pipe to detect the water flow velocity. But the water will generate impact force and water pressure during the flow process, which the flow velocity meter cannot detect, resulting in inaccurate water flow velocity measurement. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a water flow velocity measuring device for water conservancy monitoring, which has the effect of improving the accuracy of water flow velocity measurement.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water flow velocity measuring device for water conservancy monitoring, comprising a water inlet tank, an outer pipe provided at the end of the water inlet tank, a gap provided between the water inlet tank and the outer pipe, a first flange fixedly installed inside the gap, the water inlet tank and the outer pipe being movably connected through the first flange, an inner cavity fixedly connected to the inner wall of the outer pipe, a pressure sensor fixedly installed inside the inner cavity, a water flow velocity meter fixedly connected to the bottom of the inner cavity, a spring provided inside the pressure sensor, the spring being electrically connected to the output end of the pressure sensor, the pressure sensor and the water flow velocity meter being bidirectionally electrically connected, an insulating outer plate fixedly connected to the other end of the spring, a foldable pipe provided inside the insulating outer plate, an inner pipe provided at one end of the foldable pipe, a gap provided between the foldable pipe and the inner pipe, a second flange fixedly installed inside the gap, the foldable pipe and the inner pipe being movably connected through the second flange.

[0007] By adopting the above technical solution, the inlet tank and the outer pipe are installed at the dam's gate. Water inside the dam is discharged through the inlet tank, and the outer pipe is fixed to the end of the inlet tank through the first flange, allowing water to enter the inlet tank and then be discharged through the outer pipe. During this process, water penetrates the interior of the foldable pipe, and the impact of the water flow causes the foldable pipe to extend. The insulating outer plate is fixed to the outside of the foldable pipe, and the edge of the insulating outer plate is supported by springs. The impact of the water flow causes the springs to deform and contract. The pressure sensor detects the water pressure on the springs, and the water flow velocity meter detects the water flow velocity. This allows the staff to determine the water flow rate based on the water pressure in megapascals, improving the accuracy of water flow velocity measurement. The inner pipe is connected to the foldable pipe through the second flange, allowing the water inside the foldable pipe to be discharged to the outside of the outer pipe.

[0008] A further feature of this invention is that a first limiting block is fixedly connected to the outside of the water inlet tank, and a second limiting block is provided on one side of the first limiting block.

[0009] By adopting the above technical solution, the first limiting block is fixed on the outside of the water inlet tank, and the second limiting block is installed at the gate of the dam, with the first limiting block and the second limiting block overlapping.

[0010] A further feature of this invention is that a limiting groove is formed inside the first limiting block, and a limiting protrusion is fixedly connected to one side of the second limiting block.

[0011] By adopting the above technical solution, the limiting protrusion extends into the limiting groove, so that the first limiting block and the second limiting block can be separated from each other, which can not only fix the water inlet tank, but also prevent the water inlet tank from being washed away by the water flow.

[0012] A further feature of this invention is that the inner side of the second limiting block is threaded with a bolt, which extends through to the outside of the second limiting block.

[0013] By adopting the above technical solution, the second limiting block is installed to the gate of the dam with bolts, which not only has a good fixing effect, but is also easy to disassemble.

[0014] A further feature of this invention is that there are two first limiting blocks, and the two first limiting blocks are distributed on the left and right sides of the water inlet tank.

[0015] By adopting the above technical solution, there are two first limiting blocks and two second limiting blocks, which can improve the limiting effect on the water inlet tank.

[0016] A further feature of this invention is that: an inlet is provided inside the water inlet tank, a threaded shaft is rotatably connected inside the inlet, a sleeve is threadedly connected to the middle of the threaded shaft, and a grid is fixedly connected to one side of the sleeve.

[0017] By adopting the above technical solution, the inside of the water inlet is blocked by a grid to prevent impurities from entering the inside of the water inlet tank. Twisting the threaded shaft causes the sleeve and the grid to move, and the grid moves to the outside of the water inlet tank, thus allowing the staff to use the grid flexibly.

[0018] A further feature of this invention is that one end of the threaded shaft extends through to the top of the water inlet tank, and a handle is fixedly connected to one end of the threaded shaft.

[0019] By adopting the above technical solution, it is relatively convenient to twist the threaded shaft by holding the handle.

[0020] A further feature of this invention is that a slide rail is fixedly connected to the other side of the water inlet, and a slider is slidably connected inside the slide rail.

[0021] By adopting the above technical solution, the slider is fixedly connected to the outside of the grille. When the grille moves, the slider will slide inside the slide rail, which can not only support the other side of the grille, but also not affect the movement of the grille.

[0022] A further feature of this invention is that a rectangular groove is provided on the top of the water inlet tank, and the grille extends into the interior of the rectangular groove.

[0023] By adopting the above technical solution, the bar is moved to the outside of the water inlet tank through the rectangular groove.

[0024] A further feature of this invention is that an anti-slip layer is fixedly connected to the bottom of the water inlet tank, and anti-slip particles are provided at the bottom of the anti-slip layer.

[0025] By adopting the above technical solution, the anti-slip layer at the bottom of the water inlet tank comes into contact with the gate, and the anti-slip effect is improved by the anti-slip particles.

[0026] The beneficial effects of this utility model are:

This utility model, through the arrangement of an inlet tank, an outer pipe, a first flange, an inner cavity, a pressure sensor, a water flow velocity meter, a spring, an insulating outer plate, a foldable pipe, and an inner pipe and a second flange, installs the inlet tank and outer pipe at the gate of a dam. Water inside the dam is discharged through the inlet tank. The outer pipe is fixed to the end of the inlet tank through the first flange, allowing water to enter the inlet tank and then be discharged through the outer pipe. During this process, water penetrates the interior of the foldable pipe, and the impact of the water flow causes the foldable pipe to extend. The insulating outer plate is fixed to the outside of the foldable pipe, and the edge of the insulating outer plate is supported by a spring. The impact of the water flow causes the spring to deform and contract. The pressure sensor detects the water pressure on the spring, and the water flow velocity meter detects the water flow rate. This allows the operator to determine the water flow rate based on the water pressure in megapascals, improving the accuracy of water flow velocity measurement. The inner pipe is connected to the foldable pipe through the second flange, allowing the water inside the foldable pipe to be discharged to the outside of the outer pipe.

This utility model, through the arrangement of a first limiting block, a second limiting block, a limiting groove, a limiting protrusion, a bolt, a threaded shaft, a sleeve, a grid, a handle, a slide rail, a slider, and a rectangular groove, fixes the first limiting block to the outside of the water inlet tank, and installs the second limiting block at the dam's gate. The first and second limiting blocks overlap, and the limiting protrusion extends into the limiting groove, allowing the first and second limiting blocks to separate each other. This not only fixes the water inlet tank but also prevents it from being washed away by the water flow. The inside of the water inlet is blocked by the grid to prevent impurities from entering the inside of the water inlet tank. Twisting the threaded shaft causes the sleeve and grid to move, displacing the grid to the outside of the water inlet tank, thus allowing the operator to use the grid flexibly.

[0036] Reference Figure 1-4A water flow velocity measuring device for water conservancy monitoring includes a water inlet tank 1, an outer pipe 2 at one end of the water inlet tank 1, a gap between the water inlet tank 1 and the outer pipe 2, a first flange 3 fixedly installed inside the gap, the water inlet tank 1 and the outer pipe 2 being movably connected via the first flange 3, an inner cavity 4 fixedly connected to the inner wall of the outer pipe 2, a pressure sensor 5 fixedly installed inside the inner cavity 4, a water flow velocity meter 6 fixedly connected to the bottom of the inner cavity 4, a spring 7 installed inside the pressure sensor 5, the spring 7 being electrically connected to the output end of the pressure sensor 5, the pressure sensor 5 and the water flow velocity meter 6 being bidirectionally electrically connected, an insulating outer plate 8 fixedly connected to the other end of the spring 7, a foldable pipe 9 installed inside the insulating outer plate 8, an inner pipe 10 installed at one end of the foldable pipe 9, and a foldable outer plate 8 being fixedly connected to the other end of the spring 7. A gap is provided between the foldable pipe 9 and the inner pipe 10. A second flange 11 is fixedly installed inside the gap. The foldable pipe 9 and the inner pipe 10 are movably connected through the second flange 11. The inlet tank 1 and the outer pipe 2 are installed at the gate of the dam. Water inside the dam is discharged through the inlet tank 1. The outer pipe 2 is fixed to the end of the inlet tank 1 through the first flange 3, so that water flows into the interior of the inlet tank 1 and then out through the outer pipe 2. During this process, water penetrates the interior of the foldable pipe 9. The impact of the water flow causes the foldable pipe 9 to extend. The insulating outer plate 8 is fixed to the outside of the foldable pipe 9, and the edge of the insulating outer plate 8 is supported by a spring 7. The impact of the water flow causes the spring 7 to deform and contract. The pressure sensor 5 monitors the water pressure on the spring 7. Pressure is tested, and the water flow velocity meter 6 detects the water flow velocity, allowing staff to determine the water flow rate based on the water pressure in megapascals, thus improving the accuracy of water flow velocity measurement. The inner pipe 10 is connected to the foldable pipe 9 via the second flange 11, allowing the water inside the foldable pipe 9 to be discharged outside the outer pipe 2. A first limiting block 12 is fixedly connected to the outside of the water inlet tank 1, and a second limiting block 13 is provided on one side of the first limiting block 12. The first limiting block 12 is fixed to the outside of the water inlet tank 1, and the second limiting block 13 is installed at the gate of the dam. The first limiting block 12 and the second limiting block 13 overlap. A limiting groove 14 is opened inside the first limiting block 12, and a limiting protrusion 15 is fixedly connected to one side of the second limiting block 13. 15 extends into the limiting groove 14, allowing the first limiting block 12 and the second limiting block 13 to separate each other. This not only secures the water inlet tank 1 but also prevents it from being washed away by the water flow. A bolt 16 is threaded onto the inner side of the second limiting block 13, extending through to its outer surface. The second limiting block 13 is then installed at the dam's gate via the bolt 16, providing excellent fixation and easy disassembly. There are two first limiting blocks 12, distributed on the left and right sides of the water inlet tank 1. The number of both first and second limiting blocks 13 is two, further enhancing the limiting effect on the water inlet tank 1. An inlet is provided inside the water inlet, with a threaded shaft 17 rotatably connected inside.A sleeve 18 is threadedly connected to the middle of the threaded shaft 17. A grille 19 is fixedly connected to one side of the sleeve 18. The interior of the water inlet is blocked by the grille 19 to prevent impurities from entering the interior of the water inlet tank 1. Twisting the threaded shaft 17 causes the sleeve 18 and the grille 19 to move, moving the grille 19 to the outside of the water inlet tank 1, thus allowing the operator to use the grille 19 flexibly. One end of the threaded shaft 17 extends to the top of the water inlet tank 1, and a handle 20 is fixedly connected to one end of the threaded shaft 17. Twisting the threaded shaft 17 by holding the handle 20 is convenient. A slide rail 21 is fixedly connected to the other side of the water inlet. A slider 22 is slidably connected inside the slide rail 21. The slider 22 is fixedly connected to the outside of the grille 19. When the grille 19 moves, the slider 22 will slide inside the slide rail 21, which not only supports the other side of the grille 19 but also does not affect the movement of the grille 19. A rectangular groove 23 is opened at the top of the water inlet tank 1, and the grille 19 extends into the rectangular groove 23. The grille 19 moves to the outside of the water inlet tank 1 through the rectangular groove 23. An anti-slip layer is fixedly connected to the bottom of the water inlet tank 1. Anti-slip particles are provided at the bottom of the anti-slip layer. The anti-slip layer at the bottom of the water inlet tank 1 contacts the gate, and the anti-slip particles enhance the anti-slip effect.

[0037] In this invention, the inlet tank 1 and the outer pipe 2 are installed at the sluice gate of the dam. Water inside the dam is discharged through the inlet tank 1. The outer pipe 2 is fixed to the end of the inlet tank 1 by the first flange 3, so that water flows into the inlet tank 1 and then out through the outer pipe 2. During this process, water enters the interior of the foldable pipe 9, and the impact of the water flow causes the foldable pipe 9 to extend. The insulating outer plate 8 is fixed to the outside of the foldable pipe 9, and the edge of the insulating outer plate 8 is supported by the spring 7. The impact of the water flow causes the spring 7 to deform and contract. The pressure sensor 5 detects the water pressure on the spring 7, and the water flow velocity meter 6 detects the water flow velocity, so that the operator can determine the water flow rate based on the water pressure in megapascals, thus improving the accuracy of water flow velocity measurement. The inner pipe 10 is connected to the foldable pipe 9 by the second flange 11, so that the water inside the foldable pipe 9 can be discharged to the outside of the outer pipe 2. The first limiting block 12 is fixed at the inlet. On the outside of tank 1, the second limiting block 13 is installed at the sluice gate of the dam. The first limiting block 12 and the second limiting block 13 overlap. The limiting protrusion 15 extends into the limiting groove 14, so that the first limiting block 12 and the second limiting block 13 can block each other. This not only fixes the water tank 1, but also prevents the water tank 1 from being washed away by the water flow. The second limiting block 13 is installed at the sluice gate of the dam by bolts 16. This not only provides a good fixing effect, but also makes it easy to disassemble. The inside of the water inlet is blocked by the grid 19 to prevent impurities from entering the inside of the water tank 1. Twisting the threaded shaft 17 causes the sleeve 18 and the grid 19 to move. The grid 19 moves to the outside of the water tank 1, so that the staff can use the grid 19 flexibly. The slider 22 is fixedly connected to the outside of the grid 19. When the grid 19 moves, the slider 22 will slide inside the slide rail 21. This not only supports the other side of the grid 19, but also does not affect the movement of the grid 19.
