Problems solved by technology

[0003] In water conservancy irrigation, when the diameter of the input pipe is larger than the diameter of the output pipe, the output pipe is prone to bursting caused by high pipe pressure. For this phenomenon, the water pressure is mostly adjusted by controlling the main valve, but in actual water conservancy irrigation Among them, most of them are temporarily assembled irrigation systems, and the utilization rate of valves in irrigation systems is extremely low. Therefore, based on the above phenomenon, under the premise of no valves to control water pressure, float ball control is used to solve the current problems.

Embodiment 1

[0024] Such as Figure 1-4 As shown in the figure, a water conservancy irrigation device for floating ball overflow of internal pipeline liquid level self-decreasing includes a surge tank 2 and a partition, a partition is arranged in the surge tank 2, and holes are arranged at the partition; One side of the partition is vertically fixed with a trigger assembly 6 inside the surge tank 2. The trigger assembly 6 includes a taper rod 61, a spherical cylinder 62 and a floating ball 63. The spherical cylinder 62 penetrates into the surge tank from top to bottom. 2, a floating ball 63 is set in the ball cylinder 62, and a tapered rod 61 is sleeved inside the floating ball 63. The top of the tapered rod 61 is fixed with the actuator assembly 4, and the actuator assembly 4 extends into the cavity on the other side of the partition from top to bottom. In the body, the diameter of the upper end surface of the tapered rod 61 is greater than the diameter of the lower end surface, a tapered...

Embodiment 2

[0028] Such as Figure 1-4 As shown, a water conservancy irrigation device used for floating ball overflow of internal pipeline liquid level self-decreasing, executive assembly 4 includes connecting rod 41, U-shaped rod 42, vertical rod 43 and baffle plate 44, and the top of surge tank 2 A U-shaped rod 42 is provided, and the two sides of the U-shaped rod 42 are respectively fixed with a vertical rod 43 and a connecting rod 41 at a vertical position, the connecting rod 41 is connected with the tapered rod 61, and the vertical rod 43 extends into the other side of the partition Inside the cavity, a baffle plate 44 is connected to the bottom end of the vertical rod 43 .

[0029] In this embodiment, the process of moving the executive assembly 4 up and down relative to the surge tank 2 is the process of covering and unmasking the holes at the partition with the baffle plate 44 in the executive assembly 4, and the covering and unmasking Covering these two actions is based on the ...

Embodiment 3

[0031] Such as Figure 1-5 As shown, a water conservancy irrigation device used for floating ball overflow of internal pipeline liquid level self-decreasing, under the U-shaped rod 42, an adjustment assembly 3 is fixed on the top of the surge tank 2, and the adjustment assembly 3 is vertically inserted into the U-shaped At the center of the rod 42; wherein the adjustment assembly 3 includes a nut 31, a screw 32 and a sleeve 33, the top of the voltage stabilizer box 2 is fixed with a sleeve 33, and the sleeve 33 is bolted with a screw 32, and the screw 32 is vertically inserted to the U The shape bar 42 ; the nut 31 is arranged under the U-shaped bar 42 , and the nut 31 is bolted to the screw 32 .

[0032] In this embodiment, the user can adjust the base height of the executive assembly 4 relative to the surge tank 2 based on the rotation of the nut 31 relative to the screw 32 according to the usage conditions in use, and shrink the base height when the base height is clear. D...

Abstract

The invention provides a floating ball overflowing type water conservancy irrigation device for self-descending of the liquid level of an inner pipeline, and relates to the field of water conservancyirrigation. The floating ball overflowing type water conservancy irrigation device comprises a pressure stabilizing box and a partition plate. According to the invention, the partition plate is arranged in the pressure stabilizing box; a hole site is arranged on the partition plate; a trigger assembly is vertically fixed to the portion, located in the pressure stabilizing box, of one side of the partition plate and comprises a conical rod, a ball cylinder and a floating ball; the ball cylinder penetrates through the pressure stabilizing box from top to bottom and stretches into the pressure stabilizing box; the floating ball is arranged in the ball cylinder; the conical rod is sleeved with the floating ball; and after the water liquid pressure in an output cavity is reduced, covering of anexecution assembly to the hole site on the partition plate is removed, and in the covering and covering removal processes, the water pressure in the pressure stabilizing box is dynamically adjusted,so that the phenomenon that an output pipe is pressed to be burst due to the fact that the pipe diameter of the output pipe is smaller than that of an input pipe is avoided.

Description

technical field [0001] The invention relates to the field of water conservancy irrigation, in particular to a water conservancy irrigation device used for the overflow of a floating ball in which the liquid level of an inner pipeline drops automatically. Background technique [0002] Water conservancy irrigation is a comprehensive science and technology that develops irrigation and drainage, regulates regional water regimes, improves farmland water conditions, prevents drought, waterlogging, salt, and alkali disasters, and promotes stable and high agricultural production.
