detailed description

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present utility model, and are not intended to limit the present utility model.

Please refer to Fig. 1, the following technical solutions are adopted in this specific embodiment: a floating gate irrigation device, which comprises a filter screen 1, a sedimentation tank 2, a gate 3, a lever 4, and a buoy 5; the filter screen 1 rear side is provided with a sedimentation tank 2. A gate 3 is provided on the rear side of the sedimentation tank 2, a lever 4 is provided on the rear side of the gate 3, and a buoy 5 and the gate 3 are respectively connected to the lower end of the lever 4.

The filter screen 1: In the small-scale farmland irrigation system, in order to prevent channel blockage, a simple filter screen can be designed. The filter screen material can be made of plastic or stainless steel, and the mesh size can be controlled to 2ⅹ2cm. It mainly filters larger floating objects (weeds, garbage, etc.).

The sedimentation tank 2 can settle larger particles in the water to prevent impacts on other components of the irrigation system.

The gate 3 can be closed by its own weight, and the gate 3 is connected with the lever 4. With the change of the water level in the farmland, the gate 3 can be opened by the buoy 5 at one end of the lever 4 for irrigation.

The lever 4 is located at the entrance of the farmland, connects the gate 3 and the buoy 5, and can be composed of a steel rod, a pulley and a wire rope.

The buoy 5 is located on one side of the farmland and can be filled with waste plastic bottles (barrels). When the water level is low, the lever 4 can be driven by gravity to open the gate 3 (the size of the opening also changes with the water level) to achieve automatic Control effect.

Example:

First, arrange the filter screen 1, choose 2ⅹ2cm plastic net and place it at 50m from the end of the canal to simply filter the channel water, block floating objects and garbage (weeds), and prevent channel blockage and impact on component functions. A sedimentation tank 2 is excavated at the bottom of the channel 20m away from the end of the canal. The vertical section is trapezoidal, allowing the particles in the water to settle to the bottom of the tank, further purifying the water quality, and preventing blockage from causing normal operation of the components. The gate 3 is set at 5m from the water inlet of the irrigation area, and the material is stainless steel with moderate density. The sealing effect between the gate 3 and the channel should be better to prevent leakage when closed; the frictional resistance between the gate 3 and the channel wall should be small (especially upward When it is opened), it prevents the situation that it cannot be opened due to high friction. The gate 3 is connected to one end of the lever 4 (channel side) through a wire. The base of the lever 4 can be poured with concrete. The material of the lever 4 is stainless steel. The length of the pulley and the layout of the pulley can be roughly calculated by force analysis. Finally, by controlling the quality of the buoy 5 (adding water or sand), it is obtained through calculation and experimentation.

The irrigation water is introduced through the irrigation canal first through the filter screen 1 to filter the larger impurities (branches, weeds, etc.); then through the sedimentation tank 2 to settle the larger particles; Descend, pull the lever 4, the gate 3 slowly opens, and the irrigation water flows into the farmland until reaching the optimal water level, the buoy 5 floats up, the gate 3 slowly descends under its own gravity, and finally closes. It can control the irrigation amount of farmland and save manpower and material resources.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
