The water inlet pipe, the water outlet pipe and the closed pipe are arranged at a certain angle and communicate with each other. On the outer surface of the end of the water inlet pipe 11, there are three annular bosses 14 of equal height arranged side by side. There is a certain interval between the three annular bosses to form two annular grooves. The annular groove at the port is the outer groove 15. , the groove formed by the interval between the inner two annular bosses is an inner groove 16; more than two openings 17 are distributed on the annular boss at the port of the water inlet pipe 11, and the radial position distribution of the openings is irregular That is, the distances between adjacent openings are not equal; the width of the inner groove 16 is the required width of a rubber sealing ring with the same diameter, and the depth of the inner groove 16 is the required depth of the rubber sealing ring. It is used to place the rubber sealing ring to ensure the sealing of the water after installation; the outlet pipe 12 has a round or square mouth, and the length should be greater than the height of the field ridge and there is a lateral screw-shaped boss 18 on its outer surface. It is used to install the floating ball body 3; the closed tube 13 is sealed for the port, so that this end is a section of closed tube that does not communicate with the outside.

With reference to accompanying drawing 3, tetrahedron frame 2 is the tetrahedron frame that has a rectangular bottom surface and three vertical sides to form, and the middle facade of three facades is positioned at the long side end of bottom surface, and other two vertical surfaces are the short side ends of both sides, There is a circular opening 21 on the middle elevation, and there is a section of extension pipe 22 extending outwards on the opening. The inner diameter of the extension pipe 22 is the same as the outer surface diameter of the annular boss 14 on the water inlet pipe 11 of the water level control pipe fitting. , so that the water inlet pipe 11 can be socketed in the extension pipe 22 of the tetrahedron frame; there is a group of bosses 23 protruding toward the axial direction on the inner wall of the extension pipe, and the number and distribution of the bosses 23 are related to the water inlet pipe of the water level control pipe fitting The number and distribution position of the openings 17 on the annular boss at the 11 ports are the same, and the width of each boss 23 is the same as the width of the corresponding opening 17 on the annular boss of the inlet pipe 11, and its axial length is the same as that of the tee pipe. The width of the outer groove 15 on the port of the water inlet pipe 11 is the same, and the radial height is equal to or slightly smaller than the depth of the outer groove 15 on the port of the water inlet pipe of the three-way pipe, so that the water inlet pipe 11 of the three-way pipe is sleeved in the extension pipe 22 , when each boss 23 on the inner wall of the extension pipe is aligned with the corresponding opening 17 on the outer annular boss on the tee pipe inlet pipe, the cuboid boss 23 can pass through the outer annular boss opening 17 and enter into the outer groove 15 and can rotate along the groove.

Referring to accompanying drawing 4, the connection block is a rectangular block with a circular hole 51 and a screw hole 52, the axes of the circular hole 51 and the screw hole 52 are perpendicular to each other and the two holes do not intersect.

Referring to accompanying drawings 1, 2, 3, 4, the floating ball body 3 for sensing water level is a hollow airtight thin-walled ball body 32 with a screw rod 31 . The screw is fixed on the outer wall and extends radially outward. Put the round hole 51 of the connection block into the screw-shaped boss 18 on the side of the outlet pipe 12 of the tee pipe and lock it with a nut to fix the tee pipe outlet pipe 12, and then screw the float screw 31 into the connection block The screw hole 52 on the float is connected with the water level control pipe 1. Rotate the installation angle of the connection block 5 and the length of the screw rod 31 to adjust the relative position of the floating ball and the outlet pipe 12 of the tee. Through the different installation positions of the connection block, the water outlet and the water level sensing part can be at a certain angle, and the angle adjustable. The floating ball body 3 is rigidly connected with the water outlet pipe 12 , that is, the water outlet pipe 12 moves together with the movement of the floating ball body 3 . Add a matching rubber sealing ring to the inner groove of the water inlet pipe of the three-way pipe and insert the water inlet pipe 11 of the three-way pipe into the extension pipe 22 of the tetrahedral frame, and make the outer annular boss opening 17 of the water inlet pipe correspond to the inside of the extension pipe The corresponding bosses 23 are aligned and pass through, so that the bosses 23 enter into the outer groove 15 of the water inlet pipe, and can relatively rotate in the annular outer groove 15 to assemble a paddy field irrigation and drainage device. Because the radial position of the opening 17 on the annular boss of the water inlet pipe is distributed on the ring, the distance between each adjacent opening is unequal and corresponds to the boss in the extension pipe on the tetrahedron frame 2 one by one. , so that the tee pipe and the tetrahedral frame can only be connected and separated at only one position on the entire circumference.

With reference to accompanying drawing 5,6,7, the paddy field drainage and irrigation water device that will assemble is installed on the paddy field ridge opening that is used for drainage and irrigation water, and the outlet pipe 12 of tee is in horizontal state when entering water, and closed pipe 13 is in vertical state. As the water intake increases the water level 6 in the paddy field, the floating ball lifts the outlet pipe 12 and the closed pipe 13 descends. Due to the falling of the closed pipe, water begins to enter the closed pipe. When the water level rises to the set water level, the floating ball The lifting makes the outlet pipe axis and the horizontal form an included angle of more than 45 degrees, and the water in the closed pipe is more than the water in the outlet pipe. Down, the three-way pipe still continues to rotate towards the closed pipe. With the rotation of more water in the closed pipe and less water in the outlet pipe, it rotates faster until the axis of the closed pipe is horizontal, the axis of the outlet pipe is vertical, and the outlet pipe When the water outlet is higher than the water level of the canal, the irrigation to the paddy field is stopped, and the irrigation operation is automatically stopped.

The weight of the outlet pipe and the closed pipe is equal. When the outlet pipe and the closed pipe are rotated to be symmetrical in the vertical direction, the critical condition is reached at this time. The weight of the water in the two pipes is the same. When the outlet pipe continues to rise, the water in the outlet pipe Water flows to the closed pipe, and one end of the closed pipe is closed, so that the weight of water in the closed pipe is greater than that of the water inlet pipe. At this time, the closed pipe continues to fall until a new balance is reached, and the three-way pipe stops rotating.

By adopting the technical solution of the present invention, the assembled paddy field irrigation and drainage device is installed on the opening of the paddy field ridge for drainage and irrigation, so that the tetrahedron frame extension pipe faces the water channel outside the field ridge, and the water level control pipe is located in the direction of the paddy field. For the case where the three pipes are perpendicular to each other, adjust the installation angle of the connecting block and the length of the screw screw to adjust the float to the point where the float will rise when the water reaches the set irrigation water level and drive the tee to rotate along the axis of the water inlet. , to reach the position where the axis of the outlet pipe and the horizontal form an angle of more than 45 degrees. After the installation and adjustment are completed, rotate the tee pipe around the axis of the outlet pipe so that the axis of the outlet pipe is in a horizontal position and the axis of the closed pipe is in a vertical state, then the water in the canal enters through the inlet pipe and flows out through the outlet pipe into the paddy field When the paddy field is filled with water, as the water level in the paddy field rises, the floating ball floats up, driving the three-way pipe to rotate, causing the outlet pipe to rise, and the closed pipe to fall. Due to the falling of the closed pipe, water begins to enter the closed pipe. When the water level is fixed, the lifting of the floating ball makes the axis of the outlet pipe and the horizontal form an angle of more than 45 degrees, and the water in the closed pipe is more than the water in the outlet pipe. At this time, due to the imbalance of water at both ends of the three-way pipe When the floating ball leaves the water surface, the tee pipe continues to rotate towards the closed pipe. With the rotation, the water in the closed pipe becomes more and the water in the outlet pipe is less, so the rotation is faster until the axis of the closed pipe is horizontal. At this time The three-way pipe stops rotating, the axis of the water outlet pipe is vertical, and the water outlet of the water outlet pipe is higher than the water level of the water channel, so that the irrigation of the paddy field is stopped, and the automatic irrigation operation is realized.

The above-mentioned embodiments only illustrate the principles and effects of the present invention, but are not intended to limit the present invention. Anyone skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention should still be covered by the claims of the present invention.
