Description

Technical Field

[0001] The utility model relates to the technical field of irrigation pipelines, in particular to a water outlet of a low-pressure irrigation pipeline. Background Art

[0002] Low-pressure irrigation water pipeline is a pipeline system used for farmland irrigation. Its characteristic is that it can transport irrigation water at a relatively low pressure. This system is usually composed of water source, water pipeline, pipe fittings, water supply and distribution devices and protective equipment. The water source can be a well, river, canal, reservoir, pond, etc. The supporting water-lifting power is mostly a pump. The water pipeline and pipe fittings are connected to form a water channel. The water supply and distribution device is generally called a water outlet, which is used to distribute water in the underground water pipeline to the field.

[0003] In the prior art, the outlet of a low-pressure irrigation pipe is usually directly opened on the main irrigation pipe. There is usually water pressure in the main irrigation pipe for conveying water, which causes the water in the main pipe to have a large impact force when it is discharged from the outlet. When the water flows into the farmland, it will impact the soil in the farmland, which will not only affect the flatness of the farmland, but also affect the normal growth of plants in the farmland. Therefore, a low-pressure irrigation pipe outlet is designed to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a low-pressure irrigation pipe water outlet.

[0005] The technical problem to be solved by the utility model is to provide a low-pressure irrigation pipe water outlet, which can reduce the water flow speed for irrigation, prevent the water flow from impacting farmland soil, ensure the flatness of the farmland, and has high practicality.

[0006] The technical problem to be solved by the utility model is to provide a low-pressure irrigation pipe water outlet, comprising an irrigation pipe, a water outlet pipe, a connecting rod and a flow-slowing cylinder, wherein the irrigation pipe is threadedly connected with the water outlet pipe, the end surfaces of the water outlet pipe are fixedly provided with connecting rods on both sides, and the connecting rod is fixedly provided with a flow-slowing cylinder.

[0007] Preferably, the water outlet pipe is L-shaped, and the inner diameter of the water outlet pipe is larger than the inner diameter of the irrigation pipe.

[0008] Preferably, the end of the water outlet pipe away from the irrigation pipe faces downward, the opening of the slow flow cylinder faces upward, and the horizontal height of the end of the water outlet pipe away from the irrigation pipe is lower than the horizontal height of the upper surface of the slow flow cylinder.

[0009] Preferably, the water outlet pipe includes a fixed plate, a rotating shaft, turbine blades and a crushing knife. The fixed plate is fixedly arranged at the inner end of the water outlet pipe, a rotating shaft is rotatably arranged at the center of the fixed plate through a bearing, turbine blades are fixedly arranged on the top of the rotating shaft, and crushing knives are fixedly arranged on both sides of the bottom of the rotating shaft.

[0010] Preferably, the upper part of the rotating shaft is in the water outlet pipe, the lower part of the rotating shaft is in the slow flow cylinder, the turbine blades are in the water outlet pipe, and the crushing knife is in the slow flow cylinder.

[0011] Preferably, the crushing knife has a double-sided blade body structure.

[0012] Preferably, the bottom of the slow-flow tube is funnel-shaped, and a sealing cover is threadedly connected to the bottom of the slow-flow tube.

[0013] Preferably, a hydrophobic ring is fixedly provided above the outer surface of the slow flow tube.

[0014] Preferably, the hydrophobic ring is made of rubber, and is in an umbrella shape with a higher level near the center and lower levels around it.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] 1. The utility model is provided with a water outlet pipe and a slow flow cylinder. When water in the irrigation pipe flows into the water outlet pipe, the diameter of the water outlet pipe is larger than the diameter of the irrigation pipe, so as to achieve the effect of slowing down the water flow speed. The water discharged from the water outlet pipe flows into the slow flow cylinder and then overflows from the top of the slow flow cylinder for irrigation, thereby further reducing the water flow speed and the impact force of the water flow, preventing the impact force of the water flow from impacting the soil in the farmland and causing the farmland to be uneven.

[0017] 2. The utility model is provided with turbine blades and crushing knives. The water flow from the water outlet pipe impacts the turbine blades, so that the rotating shaft rotates, driving the crushing knives to rotate. The crushing knives crush the impurities in the slow flow tube to prevent the impurities from clogging the gap between the water outlet pipe and the slow flow tube, ensuring that water overflows from the slow flow tube normally. The rotation of the crushing knives can stir the soil in the slow flow tube, making it convenient for the soil to overflow from the slow flow tube with the water, preventing the soil from gathering in the slow flow tube.

[0018] 3. The utility model is provided with a sealing cover. When there are too many gravels in the slow-flow tube, the bottom of the slow-flow tube is funnel-shaped, so the gravels are gathered in the center of the bottom of the slow-flow tube. The sealing cover can be unscrewed to facilitate the discharge of the gravels in the slow-flow tube, and the inside of the slow-flow tube can be cleaned conveniently, thereby ensuring the slow-flow effect of the slow-flow tube.

[0019] 3. The utility model is provided with a hydrophobic ring. When the water in the slow-flow tube overflows, it flows onto the hydrophobic ring, diffuses to the surroundings through the hydrophobic ring, and then falls, further reducing the impact of the water flow on the soil in the farmland. The hydrophobic ring can prevent the water flow from contacting the outer surface of the slow-flow tube, prevent the outer surface of the slow-flow tube from getting wet, prevent the slow-flow tube from rusting, and ensure the service life of the slow-flow tube.

[0027] Example:

[0028] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a low-pressure irrigation pipe outlet, including an irrigation pipe 1, a water outlet pipe 2, a connecting rod 3 and a flow-slowing cylinder 4. The water outlet pipe 2 is threadedly connected to the irrigation pipe 1, and the connecting rod 3 is fixedly provided on the left and right side surfaces of the end of the water outlet pipe 2, and the flow-slowing cylinder 4 is fixedly provided on the connecting rod 3.

[0029] During actual use, when the water in the irrigation pipe 1 flows into the water outlet pipe 2, since the diameter of the water outlet pipe 2 is larger than the diameter of the irrigation pipe 1, the water flow speed is slowed down, and the water discharged from the water outlet pipe 2 flows into the slow flow tube 4, and then overflows from the top of the slow flow tube 4 for irrigation, further reducing the water flow speed, reducing the impact force of the water flow, preventing the impact force of the water flow from impacting the soil in the farmland, and preventing the farmland from being uneven.

[0030] In this embodiment, the water outlet pipe 2 is L-shaped, and the inner diameter of the water outlet pipe 2 is larger than the inner diameter of the irrigation pipe 1 , so that the water outlet pipe 2 can slow down the flow of water in the irrigation pipe 1 .

[0031] In the present embodiment, the end of the water outlet pipe 2 away from the irrigation pipe faces downward, the opening of the slow flow tube 4 faces upward, and the horizontal height of the end of the water outlet pipe 2 away from the irrigation pipe is lower than the horizontal height of the upper surface of the slow flow tube 4, so that the water in the water outlet pipe 2 can enter the slow flow tube 4 conveniently, and the slow flow tube 4 can slow the flow of the water discharged from the water outlet pipe 2.

[0032] In this embodiment, the water outlet pipe 2 includes a fixed plate 201, a rotating shaft 202, a turbine blade 203 and a crushing knife 204. The fixed plate 201 is fixedly arranged at the inner end of the water outlet pipe 2. The rotating shaft 202 is rotatably arranged at the center of the fixed plate 201 through a bearing. The turbine blade 203 is fixedly arranged on the top of the rotating shaft 202. The crushing knives 204 are fixedly arranged on both sides of the bottom of the rotating shaft 202.

[0033] In this embodiment, the upper part of the rotating shaft 202 is located in the water outlet pipe 2, the lower part of the rotating shaft 202 is located in the slow flow tube 4, and the turbine blades 203 are located in the water outlet pipe 2, and the crushing knife 204 is located in the slow flow tube 4, so that the water flow in the water outlet pipe 2 can impact the turbine blades 203, so that the rotating shaft 202 rotates, driving the crushing knife 204 to rotate, thereby achieving the effect of crushing the impurities in the slow flow tube 4.

[0034] In this embodiment, the crushing blade 204 is a double-sided blade structure, and the debris in the slow flow tube 4 can be crushed regardless of whether the rotating shaft 202 rotates clockwise or counterclockwise.

[0035] By providing turbine blades 203 and crushing knives 204, water flow from the water outlet pipe 2 impacts the turbine blades 203, causing the rotating shaft 202 to rotate, driving the crushing knives 204 to rotate, and the crushing knives crush the impurities in the slow flow tube 4 to prevent the impurities from clogging the gap between the water outlet pipe 2 and the slow flow tube 4, ensuring that water can overflow from the slow flow tube 4 normally, and the rotation of the crushing knives 204 can stir the soil in the slow flow tube 4, making it convenient for the soil to follow the water to overflow outside the slow flow tube 4, preventing the soil from gathering in the slow flow tube 4.

[0036] In this embodiment, the bottom of the slow flow tube 4 is funnel-shaped, and a sealing cover 401 is threadedly connected to the bottom of the slow flow tube 4 .

[0037] By providing a sealing cover 401, when there are too many gravels in the slow flow tube 4, since the bottom of the slow flow tube 4 is funnel-shaped, the gravels can be gathered in the center of the bottom of the slow flow tube 4, and by unscrewing the sealing cover 401, the gravels in the slow flow tube 4 can be discharged conveniently, and the inside of the slow flow tube 4 can be cleaned conveniently, thereby ensuring the slow flow effect of the slow flow tube 4.

[0038] In this embodiment, a hydrophobic ring 402 is fixedly disposed above the outer surface of the slow flow tube 4 .

[0039] In this embodiment, the hydrophobic ring 402 is made of rubber and is in an umbrella shape with a higher level near the center and lower levels around it, so that water overflowing from the top of the slow flow tube 4 can flow around and fall off.

[0040] By providing a hydrophobic ring 402, when the water in the slow-flow tube 4 overflows, it flows onto the hydrophobic ring 402, diffuses to the surroundings through the hydrophobic ring 402, and then falls, further reducing the impact of the water flow on the soil in the farmland. The hydrophobic ring 402 can prevent the water flow from contacting the outer surface of the slow-flow tube 4, prevent the outer surface of the slow-flow tube 4 from getting wet, prevent the slow-flow tube 4 from rusting, and ensure the service life of the slow-flow tube 4.

[0041] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
