[0029] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0030] See also Figure 1 This embodiment introduces a highly efficient irrigation device for rice cultivation, primarily comprising an irrigation box 1, a partition 2, and a shielding mechanism 3. The irrigation box 1 includes a box body 11, a water inlet pipe 12, a drain outlet 13, and support columns 14. One side of the box body 11 is open, i.e., it lacks a side panel. The opposite side is provided with a connected water inlet pipe 12, which is connected to a corresponding water supply pipeline. The drain outlet 13 is offset from the orientation of the water inlet pipe 12 and is located at the bottom of the side of the box body 11 that lacks an opening and water inlet pipe 12, communicating with the bottom end of the interior of the box body 11.

[0031] In order to avoid the water in the water inlet pipe 12 from flowing out from the opening side and affecting the shielding mechanism 3, a partition plate 2 is arranged at the bottom end inside the box 11 and close to the opening of the irrigation box 1, the height of the partition plate 2 is less than the height of the box plate, so that the space above the partition plate 2 is not shielded by the box 11, and the inside of the box 11 can be seen through the gap between the partition plate 2 and the box 11, but the partition plate 2 and the box 11 together enclose a cavity, and the drain 13 is in communication with the cavity. In this way, the water in the water inlet pipe 12 enters the cavity and is discharged from the drain 13. The support columns 14 are arranged at the bottom four corners of the box 11, for installation in the rice field and to ensure that the bottom of the box 11 has a certain distance from the rice field.

[0032] The shielding mechanism 3 includes a baffle 31, an adjusting member 32 and a floating plate 33. The baffle 31 is located inside the box 11 and adheres to the inner side of the box 11, and shields the communication between the water inlet pipe 12 and the box 11, when the baffle 31 completely covers the end of the water inlet pipe 12, the water is not easy to enter the inside of the box 11, when the baffle 31 moves down to expose the end of the water inlet pipe 12, the external water source can enter the box 11 through the water inlet pipe 12, and can be discharged from the drain 13.

[0033] The floating plate 33 is located below the box 11 and at the middle segment position of the support column 14, in actual use, after the box 11 is installed in the rice field, the bottom thereof is not planted with rice, but is in communication with the rice field, that is, the bottom of the box 11 has a water pool consistent with the water level of the rice field, and the floating plate 33 is placed on the water pool, when the water level of the rice field drops, the floating plate 33 will move down with the water level of the water pool. In order to avoid impurities in the rice field entering the water pool through the water flow and affecting the floating of the floating plate 33, a filter screen (not shown in the figure) is arranged around the support column 14 and close to the floating plate 33, which surrounds the floating plate 33 and blocks the impurities from entering, to ensure the normal floating of the floating plate 33.

[0034] As Figure 2 and Figure 4As shown, the adjusting member 32 connects the floating plate 33 and the baffle 31, and is mainly composed of a horizontal rod one 321, a horizontal rod two 322, a longitudinal rod 323 and a limiting nut 324. The horizontal rod one 321 and the horizontal rod two 322 are horizontally arranged, the number of the horizontal rod one 321 is preferably two, one end of which is connected with the baffle 31, and the other end is horizontally and vertically connected with the horizontal rod two 322, the surface of the horizontal rod two 322 is provided with a hole through which the longitudinal rod 323 passes, the upper half of the longitudinal rod 323 is a threaded part, and the lower half is a smooth part, so that the threaded part passes through the horizontal rod two 322, in order to fix the relative position between the longitudinal rod 323 and the horizontal rod two 322, the limiting nut 324 is screwed with the threaded part at the top and the bottom of the horizontal rod two 322, and is used for limiting the longitudinal rod 323. The bottom of the box body 11 is provided with a hole through which the smooth part passes, the bottom end of the smooth part is located below the box body 11 and is connected with the floating plate 33, the height of the floating plate 33 is changed, and the baffle 31 can be changed by the adjusting member 32. In order to improve the stability of the longitudinal movement, the end of the horizontal rod two 322 can be in contact with the side wall of the box body 11, and it is emphasized that the position of the longitudinal rod 323 passing through the box body 11 is located outside the partition plate 2, so as not to affect the sealing of the bottom of the chamber of the box body 11, and to facilitate the change of the relative position between the longitudinal rod 323 and the horizontal rod two 322.

[0035] When the highest water level of the rice field changes, the relative position between the longitudinal rod 323 and the horizontal rod two 322 can be changed by rotating the limiting nut 324, so that the distance between the floating plate 33 and the bottom of the box body 11 is changed, so as to adapt to the change of the highest water level.

[0036] In order to ensure that the baffle 31 can completely cover the end of the water inlet pipe 12 when the floating plate 33 is located at the highest water level and cannot continue to move upward, the water inlet pipe 12 can be arranged at the top of the side wall of the box body 11, and the top end of the baffle 31 is in contact with the top end of the box body 11 when the baffle 31 completely covers the water inlet pipe 12, so as to achieve the purpose of not being able to continue to move upward. It can also be realized by the telescopic cylinder one 4 and the limiting plate one 5, that is, when there is still a distance between the top of the baffle 31 and the top end of the box body 11 after the baffle 31 completely covers the water inlet pipe 12, the top of the horizontal rod one 321 is attached to the limiting plate one 5. The movable end of the telescopic cylinder one 4 is connected with the limiting plate one 5, and the fixed end is installed at the top of the box body 11, at this time, under the limiting of the limiting plate one 5, the baffle 31 cannot continue to move upward when it is completely covered with the end of the water inlet pipe 12, and the floating plate 33 is at the highest water level. When the floating plate 33 moves downward, the baffle 31 moves downward, indicating that the water level of the rice field decreases, and the end of the water inlet pipe 12 is exposed to irrigation operation.

[0037] When the floating plate 33 cannot normally move up and down due to external factors and the like, the up and down movement of the baffle plate 31 can be realized through the telescopic cylinder two 6 and the limiting plate two 7 and the telescopic cylinder one 4 and the limiting plate one 5. The limiting plate two 7 is located on the side of the limiting plate one 5 and is connected with the movable end of the telescopic cylinder two 6, and the fixed end of the telescopic cylinder two 6 is connected with the top of the box body 11. When the floating plate 33 is in a normal state, the limiting plate two 7 is located below the horizontal rod one 321 and has a fixed interval, and the interval is at least consistent with the diameter of the end of the water inlet pipe 12. When the floating plate 33 cannot normally float up and down, if the water level of the paddy field reaches the highest water level, the limiting plate two 7 is driven through the telescopic cylinder two 6 to move the baffle plate 31 to a position completely covering the end of the water inlet pipe 12, and vice versa. When the water level of the paddy field decreases, the limiting plate one 5 is driven through the telescopic cylinder one 4 to move downward, pushes the horizontal rod one 321 to move the baffle plate 31 downward, and performs corresponding irrigation operation. In order to know the water level of the water hole where the floating plate 33 is located in time, corresponding water level sensors (not shown in the figure) are arranged on the outside of the box body 11, and the water level of the liquid surface where the floating plate 33 is located can be known in time through the water level sensors.

[0038] Therefore, when the floating plate 33 is in a normal state, the interval between the floating plate 33 and the bottom of the box body 11 is adjusted after the highest water level of the paddy field is determined, so that the baffle plate 31 completely covers the end of the water inlet pipe 12 when the floating plate 33 is in the highest water level state (that is, the initial interval between the floating plate 33 and the bottom of the box body 1). When the water level decreases, the floating plate 33 moves downward to drive the baffle plate 31 to move downward, the water source can enter the box body 11 from the water inlet pipe 12 and be discharged from the drain 13 to perform irrigation, until the baffle plate 31 completely covers the end of the water inlet pipe 12 again when the water level reaches the highest water level. When the floating plate 33 is in an abnormal state and cannot normally float up and down, the baffle plate 31 is pushed downward through the telescopic cylinder one 4 and the limiting plate one 5, and the baffle plate 31 is pushed upward through the telescopic cylinder two 6 and the limiting plate two 7, so that normal irrigation can be maintained and maintenance personnel can be given maintenance time.

[0039] The water release can be self-adaptively adjusted according to the water level through the shielding mechanism 3, without the need of additionally arranging an electric control valve to remotely control the water release, so that the equipment cost is reduced, the water release can be effectively realized in time, and the irrigation efficiency is improved. When the floating plate 33 fails, the telescopic cylinder one 4, the limiting plate one 5, the telescopic cylinder two 6 and the limiting plate two 7 can be used to adjust the water release, so that the water level of the paddy field is kept at the highest water level state, and the personnel can be given time for troubleshooting and maintenance.

[0040] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various modifications and changes to the above embodiment without departing from the technical thought of the utility model, and these modifications and changes should all belong to the protection scope of the utility model.
