Description

Technical Field

[0001] This invention relates to the field of irrigation technology, and more particularly to a patch-type irrigation device with anti-clogging function. Background Technology

[0002] Drip irrigation is a highly efficient and water-saving irrigation method widely used in agricultural production. The commonly used drip irrigation emitters in existing systems have a relatively simple structure, mostly with only one outlet. Because irrigation water often contains impurities of varying sizes, although drip irrigation systems are usually equipped with filtration devices, some debris can still enter the emitter.

[0003] In practical use, large particles of debris often cannot pass through the outlet hole alone and tend to remain at the opening, while small particles can enter the gaps around the opening with the water flow. When large particles of debris partially block the outlet hole, small particles accumulate around them, further filling and compacting the gaps, creating a synergistic blockage. This synergistic effect exacerbates the blockage, making the outlet hole more easily and completely sealed. Furthermore, the interlocking of large and small particles at the outlet hole makes it even harder for the water flow to clear the blockage, leading to frequent clogging of the emitter and severely affecting the normal operation and irrigation effect of the drip irrigation system. Summary of the Invention

[0004] To solve or partially solve the problems existing in related technologies, the present invention provides a patch-type water dispenser with anti-clogging function, which aims to solve the technical problem of severe blockage of the water outlet caused by the interlocking of large and small particles.

[0005] The above-mentioned patch-type water emitter with anti-clogging function includes a water emitter body 1; The water dispenser body 1 is provided with a sand separating trough 101, and a sand separating component 108 for separating impurities of different sizes is provided in the sand separating trough 101 along its length direction; the sand separating component 108 divides the sand separating trough 101 into an upper flow channel 1011 and a lower flow channel 1012. The sand separating trough 101 is provided with a water inlet trough 102 on the left side, and the water inlet trough 102 is connected to the left end of the downstream channel 1012 through a first connecting channel 105. The right side of the sand separating trough 101 is provided with a coarse sand outlet trough 103 and a fine sand outlet trough 104, with the fine sand outlet trough 104 located above the coarse sand outlet trough 103. The right end of the lower channel 1012 is connected to the coarse sand outlet channel 103 through the second connecting channel 106, and the right end of the upper channel 1011 is connected to the fine sand outlet channel 104 through the third connecting channel 107. The water emitter body 1 is attached to the inner wall of the drip irrigation pipe 2 and the drip irrigation pipe 2 has water outlet holes corresponding to the positions of the coarse sand outlet 103 and the fine sand outlet 104.

[0006] In some designs, the sand separating component 108 employs a filter screen structure.

[0007] In some embodiments, the sand-dividing component 108 includes sand-dividing plates 1081 spaced apart along the length of the sand-dividing trough 101; The upper end of the sand-dividing plate 1081 is inclined to the left and includes a first inclined section 10811 and a second inclined section 10812 located below it; the angle between the second inclined section 10812 and the water flow direction is smaller than the angle between the first inclined section 10811 and the water flow direction.

[0008] In some schemes, in two adjacent sand-dividing sections 1081, the lower end of the second inclined segment 10812 of the left sand-dividing section 1081 is located to the right of the upper end of the second inclined segment 10812 of the right sand-dividing section 1081.

[0009] In some embodiments, part of the sand-dividing plate 1081 further has a third inclined section 10813, which is located above the first inclined section 10811, and the angle between the third inclined section 10813 and the water flow direction is smaller than the angle between the first inclined section 10811 and the water flow direction. The sand-dividing plate 1081 with the third inclined section 10813 and the sand-dividing plate 1081 without the third inclined section 10813 are alternately arranged along the length direction of the sand-dividing trough 101.

[0010] In some designs, the height of the upper sidewall of the first connecting groove 105 is lower than the height of the upper end of the second inclined section 10812.

[0011] In some designs, the left end of the water inlet trough 102 extends through the water dispenser body 1.

[0012] In some designs, the bottom of the water inlet tank 102 is provided with water inlet holes 1021, which are inclined to the right.

[0013] In some designs, the lower sidewall of the downflow channel 1012 is corrugated.

[0014] In some embodiments, the upper sidewall of the upper flow channel 1011 is corrugated, and the peak height, trough depth and amplitude of the corrugations on the upper sidewall are all smaller than the peak height, trough depth and amplitude of the corrugations on the lower sidewall of the lower flow channel 1012, thus matching the water flow velocity in the upper flow channel 1011.

[0015] The technical solution provided by this invention may include the following beneficial effects: This application separates large and small particles in the water flow by setting a water distribution component inside the emitter, and the particles flow out of the drip irrigation pipe from different outlets. This effectively reduces the interlocking of large and small particles in the same outlet, making it easier for the water flow to clear blockages caused by large particles, thus effectively reducing the technical problem of clogging the emitter outlet.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0020] like Figure 1 and Figure 2 and Figure 8 As shown in the figure, the water emitter with anti-clogging function provided in this embodiment of the invention mainly consists of an emitter body 1, a sand-dividing trough 101, an upper flow channel 1011, a lower flow channel 1012, a water inlet trough 102, a coarse sand outlet trough 103, a fine sand outlet trough 104, a first connecting trough 105, a second connecting trough 106, a third connecting trough 107, and a sand-dividing plate 1081. The emitter body 1 is a rectangular plate structure and is the main basic component, made of rigid plastic.

[0021] For ease of description, the vertical and horizontal directions of the watering device body 1 are defined as shown in the figure, and the length direction of the watering device body 1 is from left to right.

[0022] The water dispenser body 1 is provided with a sand separating trough 101. The sand separating trough 101 is rectangular in shape and its length direction is from left to right. The sand separating trough 101 is provided with a sand separating component 108 along its length direction for separating impurities of different sizes. The sand separating component 108 divides the sand separating trough 101 into an upper flow channel 1011 and a lower flow channel 1012. The sand separating trough 101 is provided with a water inlet trough 102 on the left side, and the water inlet trough 102 is connected to the left end of the downstream channel 1012 through a first connecting channel 105. The right side of the sand separating trough 101 is provided with a coarse sand outlet trough 103 and a fine sand outlet trough 104, with the fine sand outlet trough 104 located above the coarse sand outlet trough 103. The right end of the lower channel 1012 is connected to the coarse sand outlet channel 103 through the second connecting channel 106, and the right end of the upper channel 1011 is connected to the fine sand outlet channel 104 through the third connecting channel 107. During installation, the irrigator is attached to the inner wall of the drip irrigation pipe 2, ensuring that the side with the sand-dividing groove 101 is in contact with the inner wall of the drip irrigation pipe 2. This seals the side of the irrigator with the sand-dividing groove 101 through the inner wall of the drip irrigation pipe 2, thereby forming a relatively closed cavity with the inlet groove 102, the sand-dividing groove 101, the coarse sand outlet groove 103, and the fine sand outlet groove 104. At the same time, water outlet holes corresponding to the positions of the coarse sand outlet groove 103 and the fine sand outlet groove 104 are opened on the drip irrigation pipe 2, so that water and debris can flow out from the corresponding outlet holes after flowing to the coarse sand outlet groove 103 and the fine sand outlet groove 104, thus drip irrigating the crops.

[0023] During drip irrigation, drip water flows through drip irrigation pipe 2 to this irrigator, and then flows into the inlet tank 102. Subsequently, the water in the inlet tank 102 enters the lower channel 1012 through the first connecting channel 105. Under the action of water pressure, some water enters the upper channel 1011 through the sand separating component 108. During this process, the sand separating component 108 leaves large particles of debris in the lower channel 1012. These large particles of debris, after flowing through the lower channel 1012 with the water, enter the coarse sand outlet tank 103 through the second connecting channel 106, and finally flow out from the corresponding outlet hole. Small particles of debris entering the upper channel 1011, after flowing through the upper channel 1011 with the water, enter the fine sand outlet tank 104 through the third connecting channel 107, and finally flow out from the corresponding outlet hole.

[0024] This application uses a sand-separating component 108 to separate large and small particles in the water flow, which then flow out of the drip irrigation pipe 2 from different outlets. This effectively reduces the interlocking of large and small particles in the same outlet, making it easier for the water flow to clear blockages caused by large particles, thus effectively reducing the technical problem of blockage in the irrigation outlet.

[0025] In some embodiments, the sand-dividing component 108 includes sand-dividing plates 1081 spaced apart along the length of the sand-dividing trough 101. The upper end of each sand-dividing plate 1081 is inclined to the left and includes a first inclined section 10811 and a second inclined section 10812 located below it. The angle between the second inclined section 10812 and the water flow direction (from left to right) is smaller than the angle between the first inclined section 10811 and the water flow direction. The angle A between the second inclined section 10812 and the water flow direction (from left to right) is between 2 and 25 degrees, and the angle B between the first inclined section 10811 and the water flow direction is between 50 and 60 degrees.

[0026] The gap between two adjacent sand-dividing plates 1081 forms a structure similar to filter holes.

[0027] Fluid simulation of this structure is as follows: Figure 3 As shown in Figure 5, when the water flow carries large and small particles of debris through the lower channel 1012, under the action of water pressure, some water and small particles of debris can enter the upper channel 1011 through the gap between the two adjacent sand separating plates 1081. Larger particles of debris, due to their greater inertia, will bounce back into the lower channel 1012 after impacting the lower side of the second inclined section 10812, thus remaining in the lower channel 1012 and effectively separating large and small particles of debris.

[0028] Meanwhile, as can be seen from the figure, a vortex will be formed between the second inclined section 10812 of the two adjacent sand-dividing plates 1081, which can effectively prevent debris from accumulating here and effectively reduce the technical problem of blockage of the sand-dividing component 108.

[0029] In this embodiment, in two adjacent sand-dividing plates 1081, the lower end of the second inclined segment 10812 of the left sand-dividing plate 1081 is located to the right of the upper end of the second inclined segment 10812 of the right sand-dividing plate 1081.

[0030] In this way, after the water flows through the gap between two adjacent sand-dividing plates 1081, the water flow direction will be slightly to the left, and large particles of debris will not easily enter the gap between the two adjacent sand-dividing plates 1081 with the water flow, further avoiding the technical problem of blockage of the sand-dividing component 108.

[0031] In this embodiment, some of the sand-dividing plates 1081 also have a third inclined section 10813, which is located above the first inclined section 10811, and the angle between the third inclined section 10813 and the water flow direction is smaller than the angle between the first inclined section 10811 and the water flow direction; the angle C between the third inclined section 10813 and the water flow direction is between 35 and 45 degrees.

[0032] The sand-dividing plate 1081 with the third inclined section 10813 and the sand-dividing plate 1081 without the third inclined section 10813 are alternately arranged along the length direction of the sand-dividing trough 101.

[0033] Fluid simulation, such as Figures 3-5 As shown, this design allows the water flow to form a vortex in two adjacent third inclined sections 10813, effectively reducing the possibility of blockage in the water distribution components. At the same time, it can guide the water flow, causing the water flow to flow slightly to the left, so that the water flow is opposite to the water flow direction in the upper channel 3 to impact and dissipate energy, and guide the flow of debris.

[0034] In this embodiment, the height of the upper sidewall of the first connecting channel 105 is lower than the height of the upper end of the second inclined section 10812, so that the water flowing in from the first connecting channel 105 will not directly impact the first inclined section 10811 and flow directly into the upper channel 1011, so that all the water will first flow into the lower channel 1012.

[0035] In some designs, the left end of the water inlet trough 102 is provided through the water irrigator body 1 to form a water inlet, so that the water flow in the drip irrigation pipe 2 can enter the water inlet trough 102.

[0036] In some designs, the bottom of the water inlet trough 102 is evenly distributed with water inlet holes 1021. The water inlet holes 1021 are tilted to the right, which helps to reduce the amount of debris in the drip irrigation pipe 2 entering the irrigation device, thereby effectively reducing the problem of irrigation device blockage.

[0037] In some designs, the lower sidewall of the lower flow channel 1012 is corrugated, as shown in fluid simulation. Figure 3 As shown, the water flow will form a vortex on the corrugated lower side, which effectively reduces the possibility of debris adhering to the side wall of the lower channel 1012, thereby further reducing the possibility of water clogging. It also has an energy dissipation effect on the water flow, which is conducive to the stability of the water flow.

[0038] In this embodiment, the upper sidewall of the upper flow channel 1011 is corrugated, which can effectively reduce the possibility of debris adhering to the sidewall of the upper flow channel 1011, thereby further reducing the possibility of water emitter blockage. The crest height, trough depth, and amplitude of the ripples on the upper sidewall are all smaller than those on the lower sidewall of the lower flow channel 1012, and are matched with the water flow velocity in the upper flow channel 1011.

[0039] In some schemes, such as Figure 7 As shown, the water separation component employs a filter screen structure. During the flow of water from the lower channel 1012 into the upper channel 1011, the filter screen effectively removes large particles, retaining them in the lower channel 1012, while small particles can pass through the mesh and enter the upper channel 1011. Although this solution achieves initial separation of large and small particles, after long-term use, the filter screen's mesh is prone to clogging due to debris accumulation, leading to obstructed water flow or reduced separation efficiency. Frequent cleaning or replacement of the filter screen may even be necessary, increasing system maintenance workload and operating costs. Therefore, the solution using a filter screen as the water separation component still suffers from technical problems such as clogging and inconvenient maintenance, requiring further optimization.
