Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural water-saving irrigation technology, specifically to a rotary diversion drip irrigation tape with anti-clogging drippers. Background Technology
[0002] In arid and semi-arid regions where water resources are scarce, drip irrigation and fertigation technologies offer good economic benefits. However, irrigation water often contains impurities such as fine sand particles and undissolved fertilizers, which can easily cause blockage of the drip irrigation tape with long-term use, leading to uneven water distribution and decreased operational performance of the drip irrigation system.
[0003] Common drip irrigation tapes include labyrinth drip tape and patch drip tape. When using labyrinth drip tape for integrated water and fertilizer irrigation, the fertilizer- and sand-containing water flowing through the labyrinth can easily accumulate and cause blockages at the 90° corners of the flow channel. Furthermore, when the pump shuts off at the end of irrigation, a negative pressure phenomenon occurs within the pipe, causing reverse osmosis at the outlet interface with the soil, leading to soil particles clogging the drippers. When using patch drip tape, the smaller inlet and narrower flow channel of the patch cause fertilizer- and sand-containing water to flow at a slower speed, easily leading to fertilizer flocculation and deposition, blocking the inlet and flow channel. This results in random blockages in the drip tape, affecting the operation of the drip irrigation system.
[0004] Therefore, a new type of rotating diverting drip irrigation tape suitable for use in arid and semi-arid regions was designed to solve the problem of easy clogging of drip irrigation tape in fertigation and extend the service life of drip irrigation tape; the dripper used in conjunction with it is not only anti-clogging but also has a self-cleaning function. Utility Model Content
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a rotating diversion drip irrigation tape with anti-clogging drippers, including a main channel and a wing channel disposed on one side of the main channel. An array of S-shaped turbulence structures are arranged at intervals along the length of the main channel. The S-shaped turbulence structures are respectively disposed at the upper top and lower bottom of the main channel. A diversion channel is arranged along the length of the wing channel. The inlet end of the diversion channel is connected to the main channel through a spiral inlet structure. The outlet end of the diversion channel is connected to the outside through an anti-clogging dripper.
[0006] Furthermore, the spiral water inlet structure includes an inclined pipe wall with protruding spiral guide strips on the pipe wall, forming a spiral water inlet channel between the spiral guide strips.
[0007] Furthermore, the diversion channel includes a primary diversion channel, a secondary diversion channel, a primary merging structure, and a secondary merging structure, which are sequentially connected from the spiral inlet structure end to the anti-clogging dripper end.
[0008] Furthermore, the primary diversion channel forms multiple secondary diversion channels after primary diversion, and the secondary diversion channels form multiple tertiary diversion channels after secondary diversion; the primary merging structure gathers the tertiary diversion channels diverted by each secondary diversion channel, and the secondary merging structure gathers the secondary diversion channels.
[0009] Furthermore, the connections between the primary diversion channel, the secondary diversion channel, the primary merging structure, and the secondary merging structure are all rounded arc-acute angle transition connections.
[0010] Furthermore, the anti-clogging dripper includes a main flow channel, a secondary flow channel, and a jet secondary flow channel arranged in a clockwise direction, with a D-shaped flow divider wall between the main flow channel, the secondary flow channel, and the jet secondary flow channel; the main flow channel is arc-shaped, with one end connected to the flow divider channel and the other end connected to the secondary flow channel; the secondary flow channel is straight, with the end furthest from the main flow channel connected to the outside of the pipe wing channel; and the jet secondary flow channel is connected between the main flow channel and the secondary flow channel.
[0011] Furthermore, the inner diameter of the jet secondary channel is smaller than the inner diameter of the main channel, and the inner diameter of the main channel is smaller than the inner diameter of the secondary channel.
[0012] Furthermore, the connection between the main flow channel and the secondary flow channel is a circular arc transition connection, and the secondary flow channel is arranged at a 45° angle at the outlet of the anti-clogging dripper.
[0013] The advantages of this utility model compared with the prior art are as follows: (1) This utility model uses an S-shaped turbulence structure and a spiral inlet to re-disturb and dissolve the sediment and flocculated fertilizer particles in the fertilizer and sand-containing water flow, thereby reducing the deposition and blockage of fertilizer and sediment in the main channel.
[0014] (2) This utility model reduces the flow speed of fertilizer- and sand-containing water during the flow process by diverting the flow channel, thereby reducing the generation of vortices and avoiding the sedimentation of mud and sand and the accumulation of fertilizer flocculation caused by vortices.
[0015] (3) This utility model uses a new type of anti-clogging dripper to make the fertilizer and sand-containing water flow form a main outflow channel and a jet secondary channel at the outlet position, which flushes the outflow dripper channel and avoids dripper blockage caused by negative pressure sucking in external mud and sand.

[0023] Example
[0024] Referring to the accompanying drawings, this embodiment discloses a rotating diversion drip irrigation tape with an anti-clogging dripper 6, including a main channel 1 and a wing channel 3 disposed on one side of the main channel 1. An array of S-shaped turbulence structures 2 are spaced apart along the length of the main channel 1. The S-shaped turbulence structures 2 are respectively disposed at the upper top 2-1 and lower bottom 2-2 within the main channel 1, and the upper top 2-1 and lower bottom 2-2 are disposed on the side wall 2-3 of the main channel 1. A diversion channel 5 is disposed along the length of the wing channel 3. The inlet end of the diversion channel 5 is connected to the main channel 1 through a spiral inlet structure 4, and the outlet end of the diversion channel 5 is connected to the outside through the anti-clogging dripper 6. The spiral inlet structure 4 includes an inclined pipe wall 4-2, on which protruding spiral guide strips 4-1 are disposed, forming a spiral inlet channel between the spiral guide strips 4-1.
[0025] The diversion channel 5 includes a primary diversion channel 5-1, a secondary diversion channel 5-2, a primary merging structure 5-4, and a secondary merging structure 5-5, which are sequentially connected from the spiral inlet structure 4 to the anti-clogging dripper 6. The primary diversion channel 5-1 forms multiple secondary diversion channels 5-2 after primary diversion, and the secondary diversion channels 5-2 form multiple tertiary diversion channels 5-3 after secondary diversion. The primary merging structure 5-4 collects the tertiary diversion channels 5-3 diverted by each secondary diversion channel 5-2, and the secondary merging structure 5-5 collects the primary merging structure 5-4. The connection points of the primary diversion channels 5-1, secondary diversion channels 5-2, primary merging structure 5-4, and secondary merging structure 5-5 are all rounded acute-angle transition connections.
[0026] The anti-clogging dripper 6 includes a main flow channel 6-2, a secondary flow channel 6-4, and a jet secondary flow channel 6-3 arranged clockwise. A D-shaped flow divider wall is provided between the main flow channel 6-2, the secondary flow channel 6-4, and the jet secondary flow channel 6-3. The main flow channel 6-2 is arc-shaped, with one end connected to the flow divider channel 5 and the other end connected to the secondary flow channel 6-4. The secondary flow channel 6-4 is straight, with its end away from the main flow channel 6-2 connected to the outside of the pipe wing channel 3. The jet secondary flow channel 6-3 connects the main flow channel 6-2 and the secondary flow channel 6-4. The inner diameter of the jet secondary flow channel 6-3 is smaller than the inner diameter of the main flow channel 6-2, and the inner diameter of the main flow channel 6-2 is smaller than the inner diameter of the secondary flow channel 6-4. The connection between the main flow channel 6-2 and the secondary flow channel 6-4 is a rounded transition connection. The secondary flow channel 6-4 is arranged at a 45° angle at the outlet of the anti-clogging dripper 6.
[0027] Specific implementation process: When implementing integrated water and fertilizer drip irrigation in arid and semi-arid regions, the fertilizer- and sand-containing water flows into the main channel 1. Passing through the S-shaped turbulence structure 2, the fertilizer- and sand-containing water flows, under the action of the S-shaped turbulence structure, form a vertical vortex flow, which carries the already deposited sediment and flocculated fertilizer back to move and dissolve, flowing into the spiral inlet 4. The spiral guide strips 4-2 further amplify the back-moving and dissolved fertilizer- and sand-containing water flow into a transverse vortex flow, flowing into the diversion channel 5. It is then divided into two channels by the primary diversion channel 5-1, and further divided into four channels by the secondary diversion channel 5-2, before converging by the primary merging structure 5- 3. The two-channel, two-stage merging structure 5-4 merges into one channel. The first and second-stage diversion channels and the first and second-stage merging structure reduce the flow velocity of the water. At the same time, the generation of water vortices is reduced by the sharp-angled bifurcation part of the arc. After the accumulation of silt is reduced, the water flows into the anti-clogging dripper 6. The D-shaped diversion channel 6-1 of the anti-clogging dripper 6 divides the water flow into a coarse jet that passes through the main channel 6-2 and a fine jet that passes through the secondary channel 6-3. The coarse jet and the fine jet collide and clean the wall in the secondary channel 6-4, and the silt blocking the secondary channel 6-4 is washed away with the water flow.
