However, the width and depth of different irrigation canals vary greatly, and fixed brackets are difficult to adjust flexibly, which makes it impossible for the measuring equipment to be accurately aligned with the optimal flow measurement section, thus affecting the accuracy of the data. Utility Model Content

[0005] The purpose of this invention is to provide a lifting and lowering support platform for multi-parameter flow velocity in irrigation canals, which solves the problem that the fixed support is difficult to adjust flexibly due to the large differences in width and depth of different irrigation canals, which makes it impossible for the measuring equipment to be accurately aligned with the optimal flow measurement section and affects the accuracy of the data.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting support platform with multiple parameters for irrigation canal flow velocity, comprising a crossbeam, with a wide-spacing adjustment mechanism provided at both ends of the crossbeam, an adjustment sleeve installed inside the crossbeam via bearings, an adjustment column connected inside the adjustment sleeve via threads, and the adjustment column penetrating the adjustment sleeve, a base plate fixedly connected to the bottom of the adjustment column, and an installation plate installed at the bottom of the base plate via bolts, the installation plate having an installation hole.

[0007] Preferably, a retaining pin is slidably connected inside the flange of the adjusting sleeve, and the retaining pin engages with the bottom of the crossbeam.

[0008] Preferably, one end of the spring is fixedly connected to the locking pin, and the other end of the spring is fixedly connected to the inner surface of the adjusting sleeve. The spring force can act on the locking pin, allowing it to be tightly engaged into the crossbeam.

[0009] Preferably, the bottom of the crossbeam has multiple slots arranged in a circular array, and the arc-shaped end of the locking pin is located within the slot. The multiple slots facilitate the locking pin's engagement with the bottom of the crossbeam after it rotates with the adjusting sleeve.

[0010] Preferably, a guide rod is fixedly connected to the upper end of the base plate. The guide rod passes through the crossbeam and is slidably connected to the crossbeam. A travel limit block is fixedly connected to the top of the guide rod.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 A multi-parameter liftable hoisting support platform for irrigation canal flow velocity includes a crossbeam 1. An adjusting sleeve 3 is mounted inside the crossbeam 1 via bearings. An adjusting column 4 is threadedly connected inside the adjusting sleeve 3, and the adjusting column 4 penetrates the adjusting sleeve 3. A base plate 5 is fixedly connected to the bottom of the adjusting column 4. A mounting plate 6 is bolted to the bottom of the base plate 5, and mounting holes are provided on the mounting plate 6. A guide rod 7 is fixedly connected to the upper end of the base plate 5, penetrating the crossbeam 1 and slidably connected to it. A travel limit block 8 is fixedly connected to the top of the guide rod 7. The guide rod 7 provides lifting guidance for the base plate 5 and the open channel flow meter mounted on the mounting plate 6, while the travel limit block 8 limits the lifting stroke of the open channel flow meter.

[0023] Please see Figures 3-4A locking pin 9 is slidably connected inside the flange of the adjusting sleeve 3, and the locking pin 9 engages with the bottom of the crossbeam 1. A spring 10 is installed inside the flange of the adjusting sleeve 3. The locking pin 9 provides a certain degree of protection against loosening after the adjusting sleeve 3 rotates. One end of the spring 10 is fixedly connected to the locking pin 9, and the other end of the spring 10 is fixedly connected to the inner surface of the adjusting sleeve 3. The elastic force of the spring 10 can act on the locking pin 9, allowing it to be tightly engaged in the crossbeam 1. The bottom of the crossbeam 1 has multiple slots arranged in a circular array, and the arc end of the locking pin 9 is located in the slot. The multiple slots facilitate the locking pin 9 to engage with the bottom of the crossbeam 1 after rotating with the adjusting sleeve 3.

[0024] Please see Figure 1 , Figure 3 Both ends of the crossbeam 1 are equipped with width adjustment mechanisms 2. These mechanisms facilitate adjustment of the overall span, making it suitable for irrigation canals of varying widths. Each width adjustment mechanism 2 includes a sliding column 21 slidably connected inside the crossbeam 1. The sliding column 21 is horizontally positioned. A support leg 22 is fixedly connected to one end of the sliding column 21 outside the crossbeam 1. An adjustment block 23 is fixedly connected to the sliding column 21, passing through and slidably connecting to the crossbeam 1. A fixing block 24 is fixedly connected to the crossbeam 1. A threaded rod 25 is mounted on the fixing block 24 via a bearing. The threaded rod 25 passes through the adjustment block 23 and is threadedly connected to it. A knob 26 is fixedly connected to the end of the threaded rod 25, and the knob 26 and the threaded rod 25 are integrally formed. The knob 26 facilitates rotation of the threaded rod 25.

[0025] The specific implementation process of this utility model is as follows: In use, the flow meter is first installed on the mounting plate 6, and then the whole assembly is placed on the irrigation canal. Adjustment is then made according to the width of the irrigation canal. Simply rotate the threaded rod 25 using the knob 26, and the adjusting block 23 moves to the sliding column 21 through the threaded engagement with the threaded rod 25, allowing the spacing of the support legs 22 to be adjusted. This achieves rapid adaptation to irrigation canals of different widths and improves the versatility of the device. Furthermore, the threaded connection of the adjusting column 4 and the bearing-supported adjusting sleeve 3 enables stepless lifting. Combined with the vertical limiting of the guide rod 7, the flow meter installed on the mounting plate 6 at the bottom of the adjusting column 4 can be accurately positioned to the optimal flow measurement section. Simultaneously, the spring force of the spring 10 presses the locking pin 9 into the slot at the bottom of the crossbeam 1, forming a mechanical self-locking mechanism. Even under water flow impact or vibration, the fixed height of the adjusting column 4 can be maintained, ensuring the accuracy of the measurement data.
