Description

Technical Field

[0001] The utility model relates to the field of water pump irrigation, in particular to a non-powered water pump irrigation device. Background Art

[0002] Generally speaking, the water level of the riverbed or river is lower than the height of the farmland. At the same time, due to the characteristic of "water flows to the lower place", it is necessary to use water conservancy projects to guide river water into the farmland.

[0003] At present, for large-scale farmland, water conservancy projects are often used to provide river water. However, for smaller farmland or independent farmland, the cost of using water conservancy projects is often not worth the cost. Therefore, research on water pump irrigation devices that do not rely on additional external power is of practical significance. Utility Model Content

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] A non-powered water pump irrigation device according to an embodiment of the utility model will be described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, a non-powered water pump irrigation device includes: a first piston pipeline 1, a second piston pipeline 2, a water inlet pipeline 3, a water hammer pipeline 4, a first piston 5, a second piston 6, a first piston rod 7, a second piston rod 8, a first check valve 9, a second check valve 10 and a third check valve 11, one end of the first piston pipeline 1 is connected, the other end of the first piston pipeline 1 is closed, and both ends of the second piston pipeline 2 are closed, wherein,

[0031] One end of the water inlet pipe 3 is arranged at one end of the first piston pipe 1 and is connected to the first piston pipe 1. The first one-way valve 9 is arranged at the other end of the water inlet pipe 3. The first one-way valve 9 restricts the water in the water inlet pipe 3 from flowing outward.

[0032] One end of the water hammer pipeline 4 is arranged at the closed end of the first piston pipeline 1 and is connected to the first piston pipeline 1;

[0033] The first piston 5 and the first piston rod 7 are respectively arranged in the first piston pipe 1, and the first piston 5 is sleeved on the first piston rod 7;

[0034] The second piston pipe 2 is arranged on the first piston pipe 1, the second piston 6 is arranged in the second piston pipe 2, the second piston rod 8 passes through the first piston pipe 1 and the second piston pipe 2, and the two ends of the second piston rod 8 are connected to the first piston 5 and the second piston 6 respectively;

[0035] The second one-way valve 10 and the third one-way valve 11 are respectively arranged on the second piston pipe 2. The second one-way valve 10 restricts the water in the second piston pipe 2 from flowing outward, and the third one-way valve 11 restricts the water outside the second piston pipe 2 from flowing inward.

[0036] In the embodiment of the utility model, the relevant staff set the non-powered water pump irrigation device in the river water, wherein the first one-way valve 9 on the water inlet pipe 3 is connected to the river water through a water pipe, the end of the water hammer pipe 4 away from the first piston pipe 1 is connected to the river water through a water pipe, the third one-way valve 11 on the second piston pipe 2 is connected to the farmland through a water pipe, and the second one-way valve 11 on the second piston pipe 2 is connected to the river water through a water pipe;

[0037] Specifically, the first piston pipe 1 in the non-powered water pump irrigation device is arranged in the vertical direction, with the open end of the first piston pipe 1 facing upward and the closed end of the first piston pipe 1 facing downward;

[0038] The water inlet pipe 3 and the water hammer pipe 4 are arranged in the horizontal direction;

[0039] The relevant staff installed the device on the river bank. It should be noted that the water inlet pipe 3 is half immersed in the river water;

[0040] When river water enters the water inlet pipe 3 along the first one-way valve 9, it will flow into the first piston pipe 1 and the water hammer pipe 4 in sequence. In this process, when the river water flows, it will drive the first piston 5 to move downward along the first piston rod 7 until the first piston 5 completely blocks the connection between the water inlet pipe 3 and the first piston pipe 1. At this time, the river water in the water hammer pipe 4 moves in a direction away from the first piston pipe 1 under the action of inertia, which causes the air pressure inside the water hammer pipe 4 to gradually decrease until it is balanced with the movement inertia of the river water inside the water hammer pipe 4 and drops to 0;

[0041] When the inertia of the river water in the water hammer pipe 4 drops to 0, it will move toward the direction close to the first piston pipe 1 again under the influence of the low pressure in the water hammer pipe 4 and push the first piston 5 upward under the action of the water hammer. At this time, the connection between the water inlet pipe 3 and the first piston pipe 1 is reopened, and the water inlet pipe 3 flows into the first piston pipe 1 through the first one-way valve 9 again. The first piston 5 reciprocates up and down during this process;

[0042] During the up and down reciprocating motion of the first piston 5, the second piston 6 is driven to reciprocate in the second piston pipe 2 through the second piston rod 8, and river water is extracted through the second one-way valve 10 and discharged through the third one-way valve 11, thereby extracting the river water into the farmland.

[0043] In summary, the unpowered water pump irrigation device disclosed in this embodiment can automatically pump water and transport it to farmland for irrigation only by relying on the flow of river water.
