Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to an intelligent method for measuring flow in water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources.

[0003] In order to obtain accurate water conservancy information, people have developed various types of flow meters. However, existing flow meters need to be installed and fixed in the pipeline during the measurement process. Often, due to the fast water flow, the flow meter becomes loose in the pipeline, resulting in inaccurate water flow data. Moreover, existing flow meters are difficult to disassemble after measurement and will remain in the pipeline for a long time, thus increasing the project cost. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose an intelligent method for measuring flow in water conservancy projects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A method for intelligent flow measurement in water conservancy projects includes the following steps:

[0007] S1: Connect the flow measurement device to the end of the pipe so that the flow measurement device and the central axis of the pipe are on the same axis;

[0008] S2: Assemble the flow measurement device at the end of the pipe to seal the connection between the flow measurement device and the pipe;

[0009] S3: Utilize the intelligent flow meter within the flow measurement device to measure the amount of water flowing at the end of the pipe.

[0010] Preferably, the flow measurement device includes an annular plate and a rotating seat rotatably connected to the annular plate. The intelligent flow meter is disposed in the rotating seat. A first sealing gasket is fixedly provided on the annular plate. The side of the first sealing gasket opposite to the annular plate abuts against the flange at the pipe port. Several support plates are evenly arranged circumferentially on the annular plate. A screw is rotatably connected to each support plate. A first sleeve is threadedly connected to the screw. A transmission part is provided on the first sleeve. A push plate is provided on the transmission part. The push plate abuts against the flange at the pipe port.

[0011] Preferably, the rotating seat includes a rotating ring rotatably connected to the annular plate and a gear ring fixedly connected to the rotating ring, and the screw is provided with a driven gear that meshes with the gear ring.

[0012] Preferably, the transmission part includes a connecting plate fixedly connected to the first sleeve, a threaded rod rotatably connected to the connecting plate, a driven bevel gear provided at the top of the threaded rod, a driving bevel gear meshing with the driven bevel gear rotatably connected to the first sleeve, the driving bevel gear being slidably connected to the screw, a second sleeve being threadedly connected to the threaded rod, and the push plate being fixedly connected to the second sleeve.

[0013] Preferably, a second guide bar is fixedly provided on the inner sidewall of the drive bevel gear, and a second groove for sliding the second guide bar is provided on the screw.

[0014] Preferably, each of the push plates is arc-shaped, and multiple push plates are displaced along the axial direction of the threaded rod to form a ring, with adjacent push plates moving against each other.

[0015] Preferably, the rotating seat further includes a threaded tube slidably connected within the rotating ring, the outer wall of the threaded tube being fixed with an external thread, and the inner wall of the pipe port being fixed with an internal thread that is threadedly connected to the external thread.

[0016] Preferably, a first guide bar is fixedly provided on the inner sidewall of the rotating ring, and a first groove for sliding the first guide bar is provided on the outer sidewall of the threaded tube.

[0017] Preferably, both the inner wall of the pipe and the outer wall of the threaded pipe are provided with extrusion bevels, and a second sealing gasket is fixed on the extrusion bevel of the threaded pipe.

[0018] Preferably, a third sleeve is threaded onto the screw, a connecting plate is fixedly mounted on the third sleeve, a tail plate fixedly mounted on the end of the connecting plate away from the third sleeve is connected to the tail plate, a third sealing gasket is fixedly mounted on the tail plate, and the third sealing gasket moves against the end of the rotating ring away from the annular plate.

[0019] Compared with existing technologies, the present invention provides an intelligent method for measuring flow in water conservancy projects, which has the following beneficial effects:

[0020] 1. The intelligent flow measurement method for water conservancy projects involves a push plate contacting the flange at the pipe port. As the push plate moves towards the annular plate, the annular plate, in conjunction with the push plate, applies a thrust to the flange and the first sealing gasket. The flow measurement device is then assembled with the pipe port. Furthermore, when the first sealing gasket deforms, it seals the flow measurement device with the pipe port. This ensures that the flow measurement device is stably installed at the pipe end and guarantees a seal at the connection between the pipe port and the flow measurement device, thereby improving the accuracy of the flow measurement results.

[0021] 2. The intelligent flow measurement method for this water conservancy project involves moving a pusher plate towards an annular plate. The annular plate, in conjunction with the pusher plate, applies a pushing force to the flange and the first sealing gasket. As the first sealing gasket is continuously squeezed and deformed, multiple annular pusher plates eventually enclose and form an annular shape. This ensures that the pusher plate can apply pressure to all positions on the flange, avoiding uneven force on the first sealing gasket caused by the pusher plate only applying force to a few positions on the flange, which would affect the sealing effect between the annular plate and the flange at the pipe port.

[0022] 3. The intelligent flow measurement method for this water conservancy project further improves the stability of the connection between the flow measurement equipment and the pipeline by screwing the threaded pipe into the pipeline. When the end of the threaded pipe is screwed into the pipeline, the second sealing gasket on the extrusion slope of the end of the threaded pipe abuts against the extrusion slope of the inner wall of the pipeline, ensuring the sealing of the connection between the flow measurement equipment and the pipeline.

[0023] 4. In this intelligent flow measurement method for water conservancy projects, when the threaded pipe is moved by the tail plate, the third sealing gasket on the tail plate abuts against the end of the rotating ring to ensure the sealing of the flow measurement equipment itself, thereby ensuring the accuracy of the flow measurement results.

[0035] Example: Refer to Figure 1 and Figure 2 A method for intelligent measurement of flow in water conservancy projects includes the following steps:

[0036] S1: Connect the flow measuring device to the end of pipe 1, so that the flow measuring device and the central axis of pipe 1 are on the same axis;

[0037] S2: Assemble the flow measurement device at the end of pipe 1 to seal the connection between the flow measurement device and pipe 1;

[0038] S3: Use the intelligent flow meter 2 in the flow measurement device to measure the amount of water flowing at the end of the pipe 1.

[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the flow measurement device includes an annular plate 3 and a rotating seat 4 rotatably connected to the annular plate 3. The intelligent flow meter 2 is installed in the rotating seat 4. A first sealing gasket 301 is fixed on the annular plate 3. The side of the first sealing gasket 301 facing away from the annular plate 3 is movably abutted against the flange 101 at the port of the pipe 1. Several support plates 5 are evenly arranged in a circle on the annular plate 3. A screw 501 is rotatably connected to each support plate 5. A first sleeve 502 is threadedly connected to the screw 501. A transmission part 6 is provided on the first sleeve 502. A push plate 7 is provided on the transmission part 6. The push plate 7 is movably abutted against the flange 101 at the port of the pipe 1.

[0040] Furthermore, the rotating seat 4 includes a rotating ring 401 rotatably connected to the annular plate 3 and a gear ring 402 fixedly connected to the rotating ring 401. The screw 501 is provided with a driven gear 5011 that meshes with the gear ring 402.

[0041] Furthermore, the transmission unit 6 includes a connecting plate 8 fixedly connected to the first sleeve 502. A threaded rod 801 is rotatably connected to the connecting plate 8. A driven bevel gear 802 is provided at the top of the threaded rod 801. A driving bevel gear 5021 that meshes with the driven bevel gear 802 is rotatably connected to the first sleeve 502. The driving bevel gear 5021 is slidably connected to the screw 501. A second sleeve 803 is threadedly connected to the threaded rod 801. The push plate 7 is fixedly connected to the second sleeve 803.

[0042] Furthermore, a second guide bar 10 is fixedly provided on the inner wall of the active bevel gear 5021, and a second slide groove 1001 for sliding the second guide bar 10 is provided on the screw 501.

[0043] Specifically, when assembling the flow measurement device at the port of pipe 1, firstly, the first sealing gasket 301 on the annular plate 3 abuts against the flange 101 at the port of pipe 1, so that the annular plate 3 and the central axis of pipe 1 are aligned. At this time, the push plate 7 is placed on the side of the flange 101 at the port of pipe 1 away from the annular plate 3. Then, the rotating ring 401 is rotated, causing the rotating ring 401 to drive the gear ring 402 to mesh with the driven gear 5011 on the screw 501. The driven gear 5011 drives the screw 501 to rotate. When the screw 501 rotates, the first sleeve 502 moves along its axial direction. It should be noted that a guide rod should be provided on the support plate 5 to limit the movement direction of the first sleeve 502. The movement of the second sleeve 803 is similar. This is common knowledge in the field and will not be elaborated here. When the first sleeve 502 moves, it drives the threaded rod 801 to move through the connecting plate 8. When the first sleeve 502 moves, it drives the active bevel gear 5021 to move. Under the action of the second guide bar 10, the active bevel gear 5021 rotates with the screw 501. When the active bevel gear 5021 rotates, it meshes with the driven bevel gear 802 on the threaded rod 801, causing the threaded rod 801 to rotate as the first sleeve 502 moves. The second sleeve 803 moves axially along the threaded rod 801, causing the second sleeve 803 to drive the push plate 7 to move towards the central axis of the pipe 1. During this period, the push plate 7 will abut against the flange 101 at the port of the pipe 1. As the push plate 7 moves towards the annular plate 3, the annular plate 3 cooperates with the push plate 7 to apply a thrust to the flange 101 and the first sealing gasket 301. The flow measurement device is assembled with the port of the pipe 1, which is convenient for subsequent quick disassembly. At the same time, when the first sealing gasket 301 deforms, it seals the flow measurement device and the port of the pipe 1.

[0044] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, each push plate 7 is arc-shaped, and multiple push plates 7 are displaced along the axial direction of the threaded rod 801 to form a ring. Adjacent push plates 7 move and abut against each other. Specifically, the threaded rod 801 rotates as the first sleeve 502 moves, and the second sleeve 803 moves along the axial direction of the threaded rod 801, so that the second sleeve 803 drives the push plate 7 to move towards the central axis of the pipe 1. During this period, the push plate 7 will abut against the flange 101 at the port of the pipe 1. As the push plate 7 moves towards the annular plate 3, the annular plate 3 cooperates with the push plate 7 to apply a pushing force to the flange 101 and the first sealing gasket 301. As the first sealing gasket 301 is continuously squeezed and deformed, multiple annular push plates 7 eventually form a ring, so that the push plate 7 can apply pressure to all positions of the flange 101, avoiding the push plate 7 only applying force to a few positions of the flange 101, which would cause uneven force on the first sealing gasket 301 and affect the sealing effect between the annular plate 3 and the flange 101 at the port of the pipe 1.

[0045] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As a preferred technical solution of the present invention, the rotating seat 4 further includes a threaded tube 403 that is slidably connected in the rotating ring 401. The outer wall of the threaded tube 403 is fixed with an external thread 4031, and the inner wall of the port of the pipe 1 is fixed with an internal thread 102 that is threadedly connected to the external thread 4031.

[0046] Furthermore, a first guide bar 4011 is fixedly provided on the inner wall of the rotating ring 401, and a first groove 4032 for sliding the first guide bar 4011 is provided on the outer wall of the threaded tube 403.

[0047] Furthermore, both the inner wall of pipe 1 and the outer wall of threaded pipe 403 are provided with extrusion bevels, and a second sealing gasket 4033 is fixed on the extrusion bevel of threaded pipe 403.

[0048] Furthermore, a third sleeve 503 is threadedly connected to the screw 501, and a connecting plate 5031 is fixedly mounted on the third sleeve 503. The end of the connecting plate 5031 away from the third sleeve 503 is connected to a tail plate 9 fixedly connected to the threaded tube 403. A third sealing gasket 901 is fixedly mounted on the tail plate 9, and the third sealing gasket 901 moves against the end of the rotating ring 401 away from the annular plate 3.

[0049] Specifically, when the rotating ring 401 rotates, it drives the threaded tube 403 to rotate via the first guide bar 4011. When the screw 501 rotates, the third sleeve 503 moves axially along the screw 501. The third sleeve 503 drives the tail plate 9 at the end of the threaded tube 403 to move via the connecting plate 5031, so that the threaded tube 403 can move into the pipeline 1 when it rotates, and the threaded tube 403 is screwed into the pipeline 1 through the thread, which further improves the stability of the connection between the flow measuring device and the pipeline 1. When the end of the threaded tube 403 is screwed into the pipeline 1, the second sealing gasket 4033 on the extrusion slope at the end of the threaded tube 403 abuts against the extrusion slope on the inner wall of the pipeline 1, ensuring the sealing of the connection between the flow measuring device and the pipeline 1. When the tail plate 9 drives the threaded tube 403 to move, the third sealing gasket 901 on the tail plate 9 abuts against the end of the rotating ring 401, ensuring the sealing of the flow measuring device itself. Thus, the flow measuring device can be stably installed at the end of the pipeline 1, and the connection between the pipeline 1 port and the flow measuring device is sealed, improving the accuracy of the flow measurement results.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
