DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following is combined with the attached Figures 1-4A further detailed description of the present application is provided.

[0033] An embodiment of the present application discloses an irrigation and drainage channel for farmland. Referring to Figure 1 , the irrigation and drainage channel includes a main drainage channel 1 and secondary drainage channels 2. The main drainage channel 1 is arranged on the edge of the farmland and is formed by concrete pouring. Its cross-section is U-shaped and mainly functions as water storage. The secondary drainage channels 2 are vertically and horizontally arranged in the farmland to introduce the water in the main drainage channel 1 into the secondary drainage channels 2, so that the farmland can be irrigated along the secondary drainage channels 2.

[0034] Furthermore, in this embodiment, the irrigation and drainage channel further includes a base 3, a water suction pipe 4, a water suction pump 41, a drainage pipe 5, a telescopic adjustment pipe 6, and an adjustment device 7. Among them, the base 3 is arranged beside the main drainage channel 1 and can be formed by cement pouring or can be built by means such as wooden boards and steel plates; the water suction pump 41 is arranged on the base 3. The water suction pipe 4 includes two sections. The first section of the water suction pipe 4 is connected to the water inlet end of the water suction pump 41, and the other end extends downward to the lower end of the main drainage channel 1. The second section of the water suction pipe 4 is connected to the water outlet end of the water suction pump 41, and the other end extends to the secondary drainage channel 2. Thus, by starting the water suction pump 41, the water in the main drainage channel 1 can be pumped into the secondary drainage channel 2 and sent to the farmland through the secondary drainage channel 2.

[0035] Referring to Figure 1 and Figure 2 , in this embodiment, one end of the drainage pipe 5 extends into the main drainage channel 1, and the other end passes through the side wall of the main drainage channel 1 and extends into the secondary drainage channel 2 and is located at the lower end of the secondary drainage channel 2; one end of the drainage pipe 5 extending into the secondary drainage channel 2 is connected to the telescopic adjustment pipe 6. The main part of the telescopic adjustment pipe 6 extends upward, and the height of the upper end pipe orifice of the telescopic adjustment pipe 6 can be adjusted by the adjustment device 7. When in use, the water flow in the farmland flows into the main drainage channel 1 along the drainage pipe 5 from the pipe orifice of the telescopic adjustment pipe 6, which can guide the water flow in the farmland and reduce the water level height in the farmland; in order to improve the drainage efficiency of the farmland when needed, multiple drainage pipes 5 can be arranged at intervals between the main drainage channel 1 and the secondary drainage channel 2 along the extension direction of the main drainage channel 1.

[0036] Referring to Figure 1 and Figure 2 , in this embodiment, the irrigation and drainage channel further includes a water level tester 8 and a controller. Among them, the water level tester 8 is arranged in the farmland to detect the height of the water level in the farmland. The controller is connected to the water level tester 8 and can receive the signal of the water level tester 8; at the same time, the controller is also respectively connected to the water suction pump 41 and the adjustment device 7. Thus, after the water level tester 8 judges the water level height, it can transmit the signal to the controller. The controller compares it with the preset water level height and can choose to start the water suction pump 41 for irrigation or start the adjustment device 7 to adjust the height of the pipe orifice of the telescopic adjustment pipe 6 to the corresponding height for drainage.

[0037] Referring to Figure 2 and Figure 3 In this embodiment, the telescopic adjusting pipe 6 includes a first pipe 61 disposed on the drain pipe 5 and a second pipe 62 slidably disposed up and down on the first pipe 61. The adjusting device 7 can drive the second pipe 62 to slide up and down. Specifically, the upper end of the first pipe 61 can be inserted into the second pipe 62. A guiding block 611 is fixed on the outer side wall of the first pipe 61. The guiding block 611 can be a rectangular block and is symmetrically arranged on the outer side wall of the upper end of the first pipe 61. A guiding groove 621 for the guiding block 611 to slide up and down is formed on the inner side wall of the second pipe 62. Through the cooperation of the guiding block 611 and the guiding groove 621, the up and down sliding of the second pipe 62 can be guided.

[0038] Referring to Figure 2 and Figure 3 In this embodiment, the adjusting device 7 includes an adjusting screw 71, a power member 72 and an adjusting ring 73. Among them, the lower end of the first pipe 61 is connected to the drain pipe 5, and the upper end portion bends upward and extends. A positioning plate is arranged inside the first pipe 61. The positioning plate and the pipe wall are connected and fixed by a rectangular rod. The lower end of the adjusting screw 71 is rotatably connected to the positioning plate. The upper end of the adjusting screw 71 extends upward along the vertical direction. The adjusting ring 73 is coaxially sleeved outside the adjusting screw 71, and the adjusting ring 73 is threadedly connected with the adjusting bolt. A connecting rod is fixed between the outer side wall of the adjusting ring 73 and the inner side wall of the second pipe 62, and the connecting rod is fixed at the upper end position of the second pipe 62.

[0039] During use, the power member 72 drives the adjusting screw 71 to rotate. Due to the mutual cooperation of the guiding block 611 and the guiding groove 621, the second pipe 62 and the adjusting ring 73 are restricted from rotating. Therefore, the adjusting screw 71 can drive the adjusting ring 73 and the second pipe 62 to slide up and down, so as to adjust the height position of the upper end opening of the second pipe 62 and adjust the length of the telescopic adjusting pipe 6, thereby adjusting the water surface height in the farmland.

[0040] Referring to Figure 2 and Figure 4, in this embodiment, the power member 72 includes a worm gear 721, a worm 722, and a motor 723. Among them, the motor 723 is fixedly installed on the base 3, the worm 722 is rotatably arranged on the base 3 by means of a support, etc., and the output end of the motor 723 is connected to the worm 722; in order to improve the stability of the adjusting screw 71, a connecting ring can be preset on the base 3 for the adjusting screw 71 to pass through and can be rotatably connected to the adjusting screw 71. The worm gear 721 is coaxially fixed to the upper end of the adjusting screw 71, the worm gear 721 meshes with the worm 722, and the motor 723 is connected to the controller; in other embodiments, the motor 723 can also be directly used to control the rotation of the worm 722. When in use, the water surface height of each time period can be set through the controller, and the motor 723 can be controlled to start to adjust the height of the nozzle of the telescopic adjusting pipe 6 so as to adjust the water surface height of the farmland.

[0041] Referring to Figure 2 and Figure 3 , in other embodiments, the telescopic adjusting pipe 6 may further include a third pipe 63. The third pipe 63 is slidably arranged up and down at the upper end of the second pipe 62, and is connected to the first pipe 61 and the second pipe 62 in the same way; a guide block 611 and a guide groove 621 are also arranged between the second pipe 62 and the third pipe 63 for guiding, and an adjusting ring 73 is arranged to cooperate with the adjusting screw 71 to control the up and down sliding of the third pipe 63. Thus, when the adjusting screw 71 rotates, the second pipe 62 and the third pipe 63 can slide up and down simultaneously, so as to further increase the adjustment range of the telescopic adjusting pipe 6. Similarly, the telescopic adjusting pipe 6 can further be formed by connecting more pipe bodies according to actual needs.

[0042] Referring to Figure 2 and Figure 3 , in an alternative embodiment, a filter screen 9 is further arranged at the upper end of the telescopic adjusting pipe 6. The filter screen 9 is arranged along the circumferential direction of the telescopic adjusting pipe 6. The water flow can be filtered through the filter screen 9 to prevent impurities from flowing into the telescopic adjusting pipe 6 and affecting the operation of the adjusting device 7. At the same time, the filter screen 9 can also be set to be detachably connected to facilitate the cleaning or replacement of the filter screen 9. Specifically, a connection groove for inserting the filter screen 9 is opened on the upper end face of the telescopic adjusting pipe 6. The connection groove is annularly opened and provided with fixing bolts. When the filter screen 9 is inserted into the connection groove, the fixing bolts can pass through the telescopic adjusting pipe 6 and the filter screen 9 in sequence and be threadedly connected to the side wall of the telescopic adjusting pipe 6, so as to lock the filter screen 9.

[0043] The implementation principle of a farmland irrigation and drainage channel in an embodiment of this application is as follows: According to the requirements for the water level height of the farmland at different time periods, the water level height requirements can be set in the controller, and the motor 723 can be started through the controller to adjust the height of the nozzle of the telescopic adjustment pipe 6, so as to drain the farmland in time and ensure the water level height of the farmland; at the same time, when the water level tester 8 detects that the water level of the farmland is too low, the water pump 41 can be started to pump the water in the main drainage channel 1 into the secondary drainage channel 2 for irrigating the farmland.

[0044] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
