Description

Technical Field

[0001] This utility model is a flow measurement device for irrigation area construction, belonging to the field of water conservancy facilities. Background Technology

[0002] Flow measurement, as a core component of irrigation district water resource management, provides crucial data support for the scientific planning, optimized allocation, and rational scheduling of irrigation water by accurately measuring water flow. During irrigation, the amount and timing of irrigation water are adjusted in real time based on flow measurement data. By precisely controlling the water consumption in each irrigation area, precision irrigation is achieved, meeting the needs of crop growth while preventing over-irrigation that leads to soil salinization and water waste. In the flow measurement work of irrigation district construction, flow meters, as one of the commonly used flow measurement devices, play a vital role. They are usually installed inside the water pipeline, enabling real-time monitoring of water flow within the pipeline and providing key data for the rational allocation and management of water resources.

[0003] Currently, the connection between the flow meter and the pipe body mainly relies on a connecting pipe, which is generally fixed to the pipe body by welding. While this welding connection method ensures a stable connection between the connecting pipe and the pipe body, it also has certain drawbacks. After welding, the connecting pipe will protrude from the pipe body surface. During actual transfer or transportation, the pipeline is inevitably subjected to various external forces. At this time, the protruding connecting pipe is easily deformed due to impacts, which will affect the normal use of the flow meter, reduce the accuracy of flow measurement, and even cause the flow meter to malfunction, affecting the flow measurement work and water resource management of the entire irrigation area. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flow measurement device for irrigation area construction to solve the problems mentioned in the background technology. This utility model realizes that the connecting pipe connecting the flow meter and the pipe body is connected to the pipe body in an assembled manner.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a flow measurement device for irrigation area construction, comprising a pipe body, a circular opening at the middle of the outer surface of the pipe body, an arc-shaped cover plate on the outer side of the circular opening, a connecting pipe that mates with the circular opening installed at the middle of the outer surface of the arc-shaped cover plate, a flow meter installed at the end of the connecting pipe away from the arc-shaped cover plate, arc-shaped plates hinged to both ends of the arc-shaped cover plate, the ends of the two arc-shaped plates away from the arc-shaped cover plate being connected by a fastener formed by a first screw and a first nut, a sealing gasket provided in the space formed by the arc-shaped cover plate and the two arc-shaped plates, the sealing gasket wrapping around the pipe body, the end of the connecting pipe away from the flow meter passing through the sealing gasket, and two sets of anti-displacement components installed between the arc-shaped cover plate and the pipe body.

[0006] Furthermore, the anti-displacement component includes a connecting plate, and the connecting plate is installed on both parallel sides of the arc-shaped cover plate. The end of the connecting plate away from the arc-shaped cover plate is provided with a positioning ear. The positioning ear is connected and fixed to the pipe body. The connecting plate is connected to the positioning ear by a fastener formed by a second screw and a second nut.

[0007] Furthermore, the side of the positioning ear facing the connecting plate has a first small hole, and the side of the connecting plate facing the positioning ear has a second small hole aligned with the first small hole. An L-shaped plate is provided on the side of the second small hole away from the first small hole. One end of the L-shaped plate is connected and fixed to the connecting plate. A third small hole aligned with the second small hole is provided on one side of the L-shaped plate. There is a gap between the third small hole and the second small hole. One end of the second screw passes through the first small hole, the second small hole and the third small hole in sequence and is then threaded to connect to the second nut.

[0008] Furthermore, flanges are fitted at both ends of the pipe body, and the flanges are connected and fixed to the pipe body. Multiple fixing holes are equidistantly spaced on one side of the flange in a ring shape.

[0009] Furthermore, each of the two arc-shaped plates has an ear plate fixedly connected to the end away from the arc-shaped cover plate. Each of the two ear plates has two first circular holes on its opposite surface. A first screw is inserted into the channel formed by the two corresponding first circular holes, and a first nut is threaded to one end of the first screw.

[0010] Furthermore, one end of the arc-shaped plate near its ear plate is equipped with a support lug for limiting the position of the first nut. The support lug is arranged parallel to the corresponding ear plate, and there is a gap between the support lug and the corresponding ear plate. One side of the support lug is provided with a second round hole that is aligned with the first round hole. One end of the first screw passes through the second round hole and is threadedly connected to the first nut.

[0011] Furthermore, the ear plate and the arc-shaped plate are integrally formed, and the two ear plates are fitted together.

[0012] The beneficial effects of this utility model are:

[0013] 1. The connecting pipe and the pipe body are assembled and fixed by a combination of arc-shaped cover plate, arc plate and sealing gasket. The connecting pipe no longer protrudes from the surface of the pipe body, reducing the possibility of deformation due to bumps during transfer or transportation, ensuring the normal use of the flow meter and the accuracy of flow measurement, and reducing maintenance costs.

[0014] 2. By using the connecting plate, positioning ear, second screw and second nut in combination, the displacement of the arc-shaped cover plate is restricted, ensuring a stable connection between the connecting pipe and the pipe body, reducing the impact of device shaking and displacement on the flow measurement accuracy, and improving the reliability of the flow measurement device in complex environments.

[0015] 3. After the first screw passes through both lugs and the support lug in sequence, tighten the first nut. This leaves the portion of the first screw between the support lug and the lug exposed, providing space for later cutting off the first screw. Similarly, after the second screw passes through the connecting plate, the positioning lug, and the L-shaped plate, tighten the second nut. This leaves the portion of the second screw between the positioning lug and the L-shaped plate exposed, providing space for later cutting off the second screw. This reduces the difficulty of disassembling the pipe body and flow meter, especially if the first screw and first nut, and the second screw and second nut, are difficult to separate due to corrosion.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-4This utility model provides a technical solution: a flow measurement device for irrigation area construction, including a pipe body 1, with flanges 4 fitted at both ends of the pipe body 1, the flanges 4 being connected and fixed to the pipe body 1, and a plurality of fixing holes being equidistantly arranged in an annular pattern on one side of the flanges 4, a circular opening 16 being opened at the middle of the outer surface of the pipe body 1, an arc-shaped cover plate 5 being provided on the outside of the circular opening 16, a connecting pipe 15 being installed at the middle of the outer surface of the arc-shaped cover plate 5 to cooperate with the circular opening 16, a flow meter 6 being installed at the end of the connecting pipe 15 away from the arc-shaped cover plate 5, and arc-shaped plates 2 being hinged to both ends of the arc-shaped cover plate 5, the ends of the two arc-shaped plates 2 away from the arc-shaped cover plate 5 being connected by a fastener formed by a first screw 12 and a first nut 13, a sealing gasket 3 being provided in the space formed by the arc-shaped cover plate 5 and the two arc-shaped plates 2, the sealing gasket 3 being wrapped around the pipe body 1, and the end of the connecting pipe 15 away from the flow meter 6 passing through the sealing gasket 3, the connecting pipe 15 and the pipe body 1 abandon the traditional welding method and innovatively adopt an assembly form for connection. This connection method achieves stable fixation through the coordinated combination of the arc-shaped cover plate 5, the arc-shaped plate 2, and the sealing gasket 3. Specifically, the arc-shaped cover plate 5 is located outside the circular opening 16 of the pipe body 1, with the connecting pipe 15 installed in the middle of its outer surface. The two ends of the arc-shaped cover plate 5 are hinged to the arc-shaped plates 2. The ends of the two arc-shaped plates 2 furthest from the arc-shaped cover plate 5 are connected by a fastener formed by the first screw 12 and the first nut 13. Within the space enclosed by these fasteners, the sealing gasket 3 tightly wraps around the pipe body 1, and the end of the connecting pipe 15 furthest from the flow meter 6 passes through the sealing gasket 3. This design offers significant advantages. The connecting pipe 15 no longer protrudes from the surface of the pipe body 1 as in traditional methods, greatly reducing the possibility of deformation due to impacts or other external forces during transfer or transportation. This effectively ensures the normal operation of the flow meter 6 and guarantees the accuracy of the flow measurement data. Because the probability of damage to the connecting pipe 15 is reduced, the frequency of maintenance and replacement is also reduced, thereby lowering the maintenance cost of the entire flow measurement device and improving economic efficiency and usage efficiency.

[0024] See Figures 1-4A connecting plate 8 is installed on each of the two parallel sides of the arc-shaped cover plate 5. A positioning ear 7 is provided at the end of the connecting plate 8 away from the arc-shaped cover plate 5. The positioning ear 7 is connected and fixed to the pipe body 1. The connecting plate 8 is connected to the positioning ear 7 by a fastener formed by a second screw 11 and a second nut 10. The connecting plate 8, positioning ear 7, second screw 11, and second nut 10 cooperate to form a stable limiting system. During installation, the second screw 11 passes through the first small hole on the positioning ear 7, the second small hole on the connecting plate 8, and then through the third small hole on the L-shaped plate 9 on one side of the connecting plate 8, and finally tightens with the second nut 10. This connection method firmly fixes the arc-shaped cover plate 5 to the pipe body 1, effectively limiting the displacement of the arc-shaped cover plate 5. When the flow measuring device is in a complex environment, such as when it is subjected to external forces causing the device to shake or displace, this limiting system plays a crucial role. It ensures that the connecting pipe 15 and the pipe body 1 always maintain a stable connection, avoiding the impact of relative position changes on the flow measuring accuracy. This enables the flow measurement device to work stably even in complex environments, greatly improving its reliability and providing strong support for the accurate monitoring of water resources in irrigation areas.

[0025] See Figures 1-3The positioning ear 7 has a first small hole on the side facing the connecting plate 8. The connecting plate 8 has a second small hole on the side facing the positioning ear 7, which is aligned with the first small hole. An L-shaped plate 9 is provided on the side of the second small hole away from the first small hole. One end of the L-shaped plate 9 is connected and fixed to the connecting plate 8. A third small hole is provided on one side of the L-shaped plate 9, which is aligned with the second small hole. There is a gap between the third small hole and the second small hole. One end of the second screw 11 passes through the first small hole, the second small hole and the third small hole in sequence and is then threaded to the second nut 10. Two arc-shaped plates 2 are each fixedly connected to an ear plate 17 at the end furthest from the arc-shaped cover plate 5. The ear plate 17 and the arc-shaped plate 2 are integrally formed, and the two ear plates 17 fit together. Two first circular holes are opened on the opposite surfaces of the two ear plates 17. A first screw 12 is inserted into the channel formed by the two corresponding first circular holes. One end of the first screw 12 is threadedly connected to a first nut 13. An ear 14 for limiting the position of the first nut 13 is installed on the end of one arc-shaped plate 2 near its ear plate 17. The ear 14 is arranged parallel to the corresponding ear plate 17, and there is a gap between the ear 14 and the corresponding ear plate 17. A second circular hole aligned with the first circular hole is opened on one side of the ear 14. One end of the first screw 12 passes through the second circular hole and is threadedly connected to the first nut 13. The first screw 12 is passed through the corresponding first circular holes on the two ear plates 17 and the second circular hole aligned with them on the ear 14 in sequence, and then the first nut 13 is screwed on. Under the constraint of the lug 14, the portion of the first screw 12 located between the lug 14 and the ear plate 17 is exposed. This design provides space for subsequent operations, facilitating the cutting off of the first screw 12 if necessary. Similarly, when installing the second screw 11, it is sequentially passed through the second small hole on the connecting plate 8, the first small hole on the positioning lug 7, and the third small hole on the L-shaped plate 9, before the second nut 10 is screwed on. In this way, the portion of the second screw 11 located between the positioning lug 7 and the L-shaped plate 9 is also exposed, similarly facilitating the later cutting off of the second screw 11. In actual use, the first screw 12 and the first nut 13, and the second screw 11 and the second nut 10 are exposed to the external environment for a long time, and may become difficult to disassemble due to corrosion. The aforementioned exposed portion plays an important role in this situation. When corrosion makes disassembly difficult, the difficulty of disassembling the tube body 1 and the flow meter 6 can be greatly reduced by cutting off the exposed portion of the screw, facilitating maintenance and component replacement of the flow measuring device.
