[0002] Farmland water conservancy construction refers to the water conservancy undertakings that serve the development of agricultural production. Its basic task is to change the natural conditions that are not conducive to the development of agricultural production through water conservancy engineering and technical measures. Using water conservancy construction to irrigate farmland is a very important task. During the irrigation process, a water retaining plate is needed to control the flow of water into the farmland during irrigation.

[0027] Example 1

[0028] like Figure 2-6As shown, the utility model provides a water baffle for farmland water conservancy irrigation, including a U-shaped frame 1, two frames protruding out of the U-shaped frame 1 are respectively provided with opposite plug-in grooves 2, a positioning plate 9 connected by a fixing wire 10 is provided at the opening on the top of the U-shaped frame 1, and an inflatable baffle door 4 plugged into the plug-in groove 2 is connected to the opposite side of the positioning plate 9 and the U-shaped frame 1, and the side area of ​​the inflatable baffle door 4 is not less than the side area of ​​the U-shaped opening of the U-shaped frame 1, and an air supply head 7 and an air outlet head 8 are connected to the top of the positioning plate 9. 7. The air outlet head 8 is connected to the inflation baffle door 4 through the ventilation pipe 6 respectively. The outer sides of the air supply head 7 and the air outlet head 8 are respectively sleeved with a protective tube 13 connected to the positioning plate 9, and the top of the protective tube 13 is connected with a sealing cover 12. The front side of the U-shaped frame 1 is connected to a front filter mesh baffle 15, and the rear side of the U-shaped frame 1 is connected to a rear filter mesh baffle 14. The bottom surface inside the U-shaped frame 1 is an inclined surface, the high end of the inclined surface corresponds to the front filter mesh baffle 15, and the low end of the inclined surface corresponds to the rear filter mesh baffle 14.

[0029] The design of the plug-in groove 2 not only facilitates the positioning and plugging of the inflatable baffle door 4, but also, the inflatable baffle door 4 is limited and squeezed by the plug-in groove 2. The inflatable baffle door 4 in the fully inflated state can seal the gap between the plug-in groove 2 and the inflatable baffle door 4, thereby improving the sealing of the inflatable baffle door 4 to block the U-shaped frame 1.

[0030] The inclined surface design of the inner bottom surface of the U-shaped frame 1 allows the side of the inflatable baffle door 4 close to the front filter mesh baffle 15 to be squeezed when the inflatable baffle door 4 is in a fully inflated state, so that the inflatable baffle door 4 in a fully inflated state can fit tightly against the front filter mesh baffle 15, so that the inflatable baffle door 4 blocks the U-shaped opening of the U-shaped frame 1. At the same time, when water is flowing through the U-shaped opening, the mud and sand on the inner bottom surface of the U-shaped frame 1 can quickly flow out of the U-shaped frame 1 under the guidance of the inclined surface, effectively preventing the mud and sand from affecting the sealing work of the inflatable baffle door 4.

[0031] The design of the sealing cover 12 and the protective tube 13 can effectively protect the air supply head 7 and the air outlet head 8 from being damaged by the external environment, and can effectively improve the working efficiency and working effect of the air supply head 7 and the air outlet head 8 when they are used.

[0032] How it works

[0033] The U-shaped frame 1 is pre-buried in the excavated water outlet, and the side of the inflatable baffle door 4 is inserted into the plug-in groove 2 of the U-shaped frame 1. The positioning plate 9 is attached to the U-shaped frame 1 and connected to the U-shaped frame 1 through the fixing wire 10. The sealing cover 12 on the outside of the air supply head 7 is opened to expose the air supply head 7, and air is supplied to the inflatable baffle door 4 through the air supply head 7. The inflatable baffle door 4 in the full air state can squeeze the plug-in groove 2 and the inclined surface of the bottom surface of the inner side of the U-shaped frame 1, so that the inflatable baffle door 4 fills the gap between the U-shaped frame 1 and the positioning plate 9, so that the inflatable baffle door 4 effectively completes the blocking work of the U-shaped mouth of the U-shaped frame 1, that is, completes the blocking work of the water baffle; when draining water, the sealing cover 12 on the outside of the air outlet head 8 is opened to expose the air outlet head 8 is exposed, the sealing head of the air outlet head 8 is opened, and the inflatable baffle door 4 quickly completes the exhaust work through the air outlet head 8 under water pressure. The inflatable baffle door 4 can quickly break away from the fit with the U-shaped frame 1 during the deflation process, and the inflatable baffle door 4 in the deflated state cannot seal the U-shaped mouth of the U-shaped frame 1. At the same time, the inflatable baffle door 4 can be quickly withdrawn from the U-shaped frame 1 through the positioning plate 9, so that the U-shaped mouth of the U-shaped frame 1 is in an open state, that is, the water passing work of the water baffle is completed. When passing water, the rear filter mesh baffle 14 and the front filter mesh baffle 15 can effectively filter large particles of impurities in the water to prevent impurities from filling the gap between the U-shaped frame 1 and the positioning plate 9, effectively improving the sealing of the inflatable baffle door 4 in the full air state.
