Description

Technical Field

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

[0002] An irrigation district refers to an irrigated area with a reliable water source and a system of water diversion, transportation, and distribution channels and corresponding drainage ditches. It is a product of human economic activities and develops along with the development of the social economy.

[0003] However, traditional irrigation area flow measurement devices still have the following shortcomings: Traditional irrigation area flow measurement devices adopt a fixed installation method. Once the installation location is determined, it is difficult to make flexible adjustments according to actual needs. Irrigation areas have a wide distribution of channels and complex terrain. The water flow conditions and measurement requirements in different locations may vary greatly. Traditional irrigation area flow measurement devices cannot effectively adjust the measurement height and direction according to the actual situation of the channels, making it difficult to obtain accurate flow data in practical applications and limiting their wide application in different irrigation area scenarios. Therefore, we have introduced an irrigation area flow measurement device. Utility Model Content

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this utility model, the lifting mechanism drives the lead screw to rotate through the second rotary motor, thereby driving the measuring component to adjust its height. This allows the flow sensor to flexibly adjust to the optimal measuring height position according to the actual situation of the irrigation area water flow, such as channel depth and water level changes. Whether the measurement is carried out in a shallow irrigation ditch or a deep water pipeline, the flow sensor can always be in the most suitable measuring position by precisely controlling the operation of the second rotary motor. This ensures that the flow velocity, flow rate and other data of the water flow can be accurately collected, improving the adaptability and measurement accuracy of the measuring device and effectively avoiding data errors caused by improper measuring height.

[0020] 2. In this utility model, the rotating mechanism utilizes the transmission combination of the first rotating motor, worm gear, and worm wheel to realize the overall rotation of the base plate and its components. This allows for convenient adjustment of the measurement direction of the measuring components. In irrigation areas, the water flow direction may change due to factors such as channel orientation and diversion gate settings. In this case, the rotating mechanism can quickly and accurately align the flow sensor with the water flow direction, ensuring the authenticity and validity of the measurement data. This flexible measurement direction adjustment function enables the device to adapt to various complex water flow conditions, greatly improving its versatility and practicality, and providing a strong guarantee for the comprehensive and accurate measurement of irrigation area flow.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A flow measurement device for irrigation area includes a base 1. Locking casters 2 are fixedly installed at the four corners of the lower end of the base 1. Mounting plates 3 are fixedly connected to the front and rear of the upper end of the base 1. A rotating mechanism 4 is inserted and installed at the rear end of the rear mounting plate 3. A base plate 5 is fixedly connected to the upper end of the rotating mechanism 4. A vertical plate 6 is fixedly connected to the rear of the upper end of the base plate 5. A sliding groove 7 is opened at the front end of the vertical plate 6. A fixing plate 8 is fixedly connected to the middle of the upper end of the base plate 5. A lifting mechanism 9 is fixedly connected to the lower end of the fixing plate 8.

[0031] In this embodiment, the lifting mechanism 9 includes a second rotary motor 91. A lower coupling 92 is fixedly mounted on the output end of the second rotary motor 91. A lead screw 93 is fixedly connected to the upper end of the lower coupling 92. An upper coupling 94 is fixedly connected to the upper end of the lead screw 93. A measuring component 95 is threaded onto the outer surface of the lead screw 93. The lower end of the second rotary motor 91 is fixedly connected to the upper end of the base plate 5. The upper end of the second rotary motor 91 is fixedly connected to the lower end of the fixed plate 8. The output end of the second rotary motor 91 passes through the lower end of the fixed plate 8 and extends to the upper end of the fixed plate 8. The upper end of the lead screw 93 is movably connected to the lower end of the vertical plate 6 via a rotating shaft. The measuring component 95 includes a transmission block 951. A slider 952 is fixedly connected to the rear end of the transmission block 951. A limit block 953 is fixedly connected to the rear end of the slider 952. A measuring component 951 is fixedly connected to the front end of the transmission block 951. A horizontal plate 954 has a flow sensor 955 fixedly installed at its front end. The inner wall of the transmission block 951 is threadedly connected to the outer surface of the lead screw 93. A slider 952 is movably sleeved in the slide groove 7. The rotating mechanism 4 includes a first rotating motor 41, a worm gear 42 fixedly installed at the output end of the first rotating motor 41, a worm wheel 43 connected to the outer surface of the worm gear 42, a base rod 44 fixedly connected to the middle of the upper end of the worm wheel 43, the front end of the first rotating motor 41 fixedly connected to the rear end of the rear mounting plate 3, and the output end of the first rotating motor 41 passing through the rear end of the rear mounting plate 3 and extending to the front end of the rear mounting plate 3. The front end of the worm gear 42 is movably connected to the rear end of the front mounting plate 3 through a rotating shaft, the lower end of the worm wheel 43 is movably connected to the upper end of the base 1 through a rotating shaft, and the upper end of the base rod 44 is fixedly connected to the lower end of the base plate 5.

[0032] It should be noted that this utility model is a flow measurement device for irrigation areas. During use, the device is pushed to the vicinity of the measurement point in the irrigation area. The locking casters 2 at the four corners of the lower end of the base 1 are used to fix the casters by locking devices on the casters 2 to prevent unnecessary movement of the device during measurement. The second rotary motor 91 of the lifting mechanism 9 is started. The output end of the second rotary motor 91 drives the lower coupling 92 to rotate, which in turn causes the lead screw 93 to start rotating. Since the transmission block 951 in the measuring component 95 is threadedly connected to the lead screw 93, and the slider 952 at the rear end of the transmission block 951 is movably sleeved in the groove 7 at the front end of the vertical plate 6, the measuring component 95 will move up and down along the axis of the lead screw 93 when the lead screw 93 rotates, thereby realizing the initial adjustment of the measurement height. According to the actual situation of the irrigation area water flow and the measurement requirements, the height of the measuring component 95 is adjusted by controlling the forward and reverse rotation and the rotation angle of the second rotary motor 91, so that the flow sensor 955 at the front end of the horizontal plate 954 is in a suitable measurement position. The location should generally ensure that the flow sensor 955 can accurately sense the flow velocity and flow rate information of the water, while avoiding collisions with obstacles such as the inner wall of the channel or pipe. When it is necessary to adjust the measurement direction, the first rotary motor 41 of the rotating mechanism 4 is started. The output end of the first rotary motor 41 drives the worm 42 to rotate. The worm 42 is connected to the worm wheel 43, so that the worm wheel 43 rotates around its axis. Since the bottom rod 44 at the middle of the upper end of the worm wheel 43 is fixedly connected to the lower end of the base plate 5, the base plate 5 and its vertical plate 6 and measuring component 95 will rotate as a whole around the axis of the worm wheel 43, thereby changing the measurement direction to adapt to the water flow measurement needs of different flow directions. According to the actual water flow direction, the direction of the measuring device is adjusted by controlling the rotation direction and angle of the first rotary motor 41 so that the flow sensor 955 faces the water flow direction, ensuring the accuracy of the measurement data. After the measurement height and direction are adjusted, the flow sensor 955 starts to work and collects relevant data on the flow velocity and water level in real time.
