Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy and irrigation, and particularly relates to a water conservancy and irrigation diversion device. Background Art

[0002] Irrigation primarily refers to the irrigation of agricultural land. Irrigation methods can be generally categorized as traditional surface irrigation, sprinkler irrigation, and micro-irrigation. Irrigation often requires the use of diversion pipes to control the direction of water flow and the area irrigated.

[0003] The existing diversion device mainly relies on sealing rings to achieve sealing when connected to external pipes. However, the current sealing rings are placed directly at the connection position and have no connection with the device or the external pipe. Therefore, deviations are prone to occur, resulting in poor sealing effects in the later stage. In addition, the current sealing effect of the sealing rings is average, and there is also a risk of leakage during long-term use. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a water conservancy irrigation diversion device to solve the problems of unstable installation position and poor sealing effect of the existing diversion device proposed in the above background technology during use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water conservancy irrigation diversion device, comprising a main pipe with a plurality of branch pipes connected to the top thereof; during irrigation, water will first enter the main pipe and then be discharged from the branch pipe to the corresponding pipe, thereby achieving the purpose of diversion irrigation; it also includes a sealing assembly, consisting of a first sealing member and a second sealing member; the bottom end of the first sealing member is engaged with the top of the branch pipe, and the second sealing member is sleeved on the middle part of the sealing assembly and bulges outward. When connected to an external pipe, it will abut against the inner wall of the pipe through the second sealing member, thereby achieving a sealing effect.

[0006] Preferably, a positioning groove is provided at an equal angle on the top surface of the branch pipe; the first sealing member is a rubber ring, and a protrusion is fixed on the bottom surface of the rubber ring to be snapped into the positioning groove. The rubber ring and the branch pipe are snapped together and installed through the protrusion, and there will be no problem of change in the position of the rubber ring in the later connection.

[0007] Preferably, a clamping column is fixed inside at least one of the positioning grooves. The clamping column is conical and is clamped into the inside of the protrusion. Through embedded installation, the installation stability of the rubber ring and the branch pipe can be further improved.

[0008] Preferably, a ring groove is provided in the middle of the rubber ring, and the second sealing member is an annular airbag sleeved in the ring groove. When the annular airbag is connected to the external pipe, it will abut against the inner wall of the pipe, thereby achieving secondary sealing.

[0009] Preferably, a permeable mesh is fixed to the inner wall of the opening of the branch pipe, and a downward-inclined closed ring is provided at the inner bottom end of the branch pipe. A blocking ball is also placed between the closed ring and the permeable mesh. When the water source is discharged through the branch pipe, the water source will push the blocking ball toward the permeable mesh. At this time, the hole on the closed ring can be opened, and the water flows through the holes of the permeable mesh and is discharged again. Conversely, when drainage is not required, the blocking ball descends under gravity and seals the closed ring.

[0010] Preferably, the diameter of the blocking ball is larger than the aperture of the closed loop, and the blocking ball is a hollow metal sphere, so that it can be pushed out by the water flow and can also have a certain gravity drop to achieve the blocking of the closed loop.

[0011] Preferably, the closed ring and the permeable mesh plate are fixed by welding, and the thickness of the two is equal.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The designed sealing component can not only ensure the stability of installation and avoid misalignment during connection, but also achieve a double sealing effect. During long-term use, there will be no leakage. The sealing component has a simple structure, is easy to process and produce, has high practicality, and improves the shortcomings of the existing diversion device in the sealing function.
