Description

Technical Field

[0001] The utility model relates to the technical field of irrigation, in particular to a patch type drip irrigation tape. Background Art

[0002] Due to its good water-saving performance, drip irrigation tape is widely used in farmers' greenhouse farmland. Drip irrigation tapes are divided into patch type drip irrigation tapes, embedded cylindrical drip irrigation tapes, labyrinth drip irrigation tapes, etc., each with its own characteristics. However, both patch type drip irrigation tapes and other types are prone to blockage. Once blocked, it will affect the water output, and thus affect the irrigation of agricultural plants.

[0003] In order to solve the blockage problem, Chinese Patent CN215223661U, a patch type drip irrigation tape, points out that to avoid the accumulation of impurities in water and block the water outlet holes, water inlet, flow channel and water outlet, a slidable filter cover is installed on the patch. The impurities in water are filtered in advance through the through holes opened on the filter cover to avoid blockage. And by pressing the filter cover, the filter cover slides inside the water storage tank. The convex posts arranged inside the water storage tank move into the through holes opened on the filter cover to extrude the impurities inside the through holes of the filter cover, improving the service life of the filter cover and avoiding the situation that no water drops out from the water outlet holes of the device.

[0004] Although the above document can solve the problem of blockage to a certain extent, there are still certain technical problems. Although the filtration is carried out in advance, the situation of blockage of the filter cover occurs relatively frequently in this way. If pressing is required every time, it is too troublesome. And the filter cover can be installed, that is, two structural parts need to be molded during manufacturing, so the cost is relatively high. Therefore, although this document can solve the problem of filtration and blockage prevention, it is not applicable in production and manufacturing.

[0005] Therefore, in order to prevent blockage by sand and gravel and facilitate manufacturing, a patch type drip irrigation tape is hereby provided. Summary of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a patch type drip irrigation tape, which solves the problem that the patch in the existing patch type drip irrigation tape is prone to blockage.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A patch type drip irrigation tape, comprising a drip irrigation tape and a drip patch. The drip patch is embedded in the inner surface of the drip irrigation tape. Grooves are formed on the surface of the drip patch, and water dripping holes are formed on the surface of the drip irrigation tape. Water inlets are formed on the surface of the grooves. The grooves are divided into three regions a, b, and c. A rib is formed between region a and region b on the surface of the grooves. A filtering structure capable of blocking and filtering sand and gravel in water is provided on the surface of the grooves. The filtering structure is divided into a first filtering structure and a second filtering structure. The first filtering structure is arranged on the surface of region b, and the second filtering structure is arranged on the surface of region a. The first filtering structure includes first blocking plates equidistantly installed in region b. Baffles are provided on the surface of the first blocking plates. First filtering grooves corresponding to the baffles are formed on the surface of region b. A second diversion plate is arranged on the surface of region b in front of the first blocking plates. The second filtering structure includes first diversion plates equidistantly installed on the surface of region a. Second filtering grooves are formed on the surface of region a near the rear sides of the first diversion plates. A second blocking plate is arranged on the surface of region a behind the first diversion plates, and openings are formed on the surface of the second blocking plate. Region a, region b, and region c are communicated, and region c is correspondingly arranged with the water dripping holes.

[0008] Through the above technical solutions, further, the first blocking plates are arranged in a wavy shape in region b, and the ends face the side of the second diversion plate. The baffles are bent backward in a curved shape and correspond to the first filtering grooves, and the ends of the baffles extend to the surface of the first filtering grooves.

[0009] Further, the second diversion plate is arranged in a curved shape, and the end of the second diversion plate faces the side of the rib.

[0010] As a preferred technical solution, an included angle is formed at the connection between the first blocking plate and the baffle.

[0011] Further, the first diversion plates are arranged in a semi-circular arc shape, and both ends of the first diversion plates do not contact the rib and the side wall of the grooves. An arc-shaped protrusion is provided on the rear end surface of the first diversion plates, and the end of the protrusion faces the opening on the surface of the second blocking plate. One end of the second blocking plate is fixedly connected to one side of the rib, and the other end is fixedly connected to the side wall of the grooves.

[0012] As a preferred technical solution, the radius of the first diversion plate is smaller than the radius of the second blocking plate, and included angles are formed at both ends of the second blocking plate.

[0013] Further, the water inlets are arranged at an inclination angle of 45°.

[0014] Compared with the prior art, the present utility model provides a patch type drip irrigation tape, which has the following beneficial effects:

[0015] 1. The patch in this drip irrigation tape can greatly prevent blockage caused by sand and gravel through the double filtration of the first filtration structure and the second filtration structure. Refer to Figure Figure 2 、 Figure 5 (the water flow direction)、 Figure 7 、 Figure 8 It can be seen that when water enters the b area through the water inlet, first, due to the action of the first baffle, the water flow direction is changed. The water flow contacts the baffle and enters the first filtration tank along the orientation of the baffle, forming a vortex, so that the sand and gravel in the water precipitate. Then, a vortex is formed again at the angle between the first baffle and the baffle connection, and the sand and gravel in the water are further precipitated. The precipitated sand and gravel will move forward along the surface of the groove in the b area, and then precipitation will occur at the second diversion plate and the side wall of the groove in the b area. When the precipitation gradually increases, the sand and gravel will be driven by the water to move to the right end, and then will be brought into the angle between the first baffle and the side wall of the groove in the b area for precipitation. The main flow channel continues to move along the groove in the b area to the groove in the a area. When the water enters the groove in the a area, the sand and gravel content in the water is relatively low, and most of the sand and gravel have precipitated in the first filtration tank. At this time, through the action of the first diversion plate, the water is introduced to both ends of the surface of the second baffle, and then a vortex phenomenon (sand and gravel precipitation) is formed. At this time, due to the impact force, the water flows towards the rear side of the first diversion plate, and then flows out through the arc-shaped protrusion towards the opening on the surface of the second baffle. When flowing, the water is precipitated again through the second filtration tank, and then flows sequentially. Through the above description, the problem of blockage prevention is achieved by adopting the method of multiple precipitation and multiple filtration, thus solving the problem that the patch in the existing patch-type drip irrigation tape is prone to blockage.

[0026] Embodiment

[0027] Please refer to Figures 1 - 8 , the present utility model provides the following technical solutions: A patch type drip irrigation tape, including a drip irrigation tape 1 and a water dripping patch 3. The water dripping patch 3 is embedded in the inner side surface of the drip irrigation tape 1. A groove 4 is opened on the surface of the water dripping patch 3. A water dripping hole 2 is opened on the surface of the drip irrigation tape 1. A water inlet 5 is opened on the surface of the groove 4. The groove 4 is divided into three regions a, b, and c. A convex strip is formed between region a and region b on the surface of the groove 4. A filtering structure capable of blocking and filtering sand and gravel in water is provided on the surface of the groove 4. The filtering structure is divided into a first filtering structure and a second filtering structure. The first filtering structure is arranged on the surface of region b. The second filtering structure is arranged on the surface of region a. The first filtering structure includes first baffles 6 installed at equal intervals in region b. A baffle 7 is provided on the surface of the first baffle 6. A first filter tank 8 corresponding to the baffle 7 is provided on the surface of region b. A second diversion plate 11 is arranged on the surface of region b in front of the first baffle 6. The second filtering structure includes first diversion plates 9 installed at equal intervals on the surface of region a. A second filter tank 12 is opened at a position near the rear side of the first diversion plate 9 on the surface of region a. A second baffle 10 is arranged on the surface of region a behind the first diversion plate. An opening is provided on the surface of the second baffle 10. Region a, region b, and region c are communicated. Region c is correspondingly arranged with the water dripping hole 2

[0028] In this implementation, the specific working principle is as follows: Water enters the groove 4 in area b through the water inlet 5, and then, under the action of the first baffle 6, the water flow direction is changed. The water flow contacts the baffle 7 and enters the first filter tank 8 along the orientation of the baffle 7, forming a vortex, thereby causing the sand and gravel in the water to precipitate. Then, another vortex is formed at the angle between the first baffle 6 and the baffle 7, and the sand and gravel in the water are further precipitated. The precipitated sand and gravel will move forward along the surface of the groove 4 in area b, and thus precipitation will occur at the second diversion plate 11 and the side wall of the groove 4 in area b. When the precipitation gradually increases, the sand and gravel will be driven by the water to move to the right end, and then will be carried into the angle between the first baffle 6 and the side wall of the groove 4 in area b for precipitation, while the main flow channel continues to move along the groove 4 in area b to the groove 4 in area a. When the water enters the groove 4 in area a, the sand and gravel content in the water is relatively low, and most of the sand and gravel have precipitated in the first filter tank 8. At this time, under the action of the first diversion plate 9, the water is introduced to both ends of the surface of the second baffle 10, and then a vortex phenomenon (sand and gravel precipitation) is formed. At this time, due to the impact force, the water flows towards the rear side of the first diversion plate 9, and then flows out through the opening on the surface of the second baffle 10 facing the arc-shaped protrusion. When flowing, the water is precipitated again through the second filter tank 12 and then flows sequentially.

[0029] In order to filter the sand and gravel in the water, according to the above, specifically refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 It can be seen that the first baffle 6 is arranged in a wavy shape in area b, and the end faces the side of the second diversion plate 11. The baffle 7 is bent backward in a curved shape and corresponds to the first filter tank 8, and the end of the baffle 7 extends to the surface of the first filter tank 8. This can cause the water to form a vortex phenomenon locally under the action of the baffle 7 when it contacts the first baffle 6 (refer to Figure 5 It can be seen). Then, along the baffle 7, the water flows into the first filter tank 8, and then the sand and gravel in the water are precipitated, and then continue to flow forward through the first baffle 6.

[0030] According to the above, when the water flows forward through the first baffle 6, in order to further filter the sand and gravel in the water and change the water flow direction, specifically refer to Figure 5 It can be seen that the second diversion plate 11 is arranged in a curved shape, and the end of the second diversion plate 11 faces the side of the rib. The water flow contacts the second diversion plate 11, and then the water flow flows towards the side of the rib. When flowing, the water flow will spread, and thus part of the water flow will flow to the front side of the first baffle 6 and form a vortex phenomenon with the side wall of the groove 4 in area b, realizing further sand and gravel precipitation.

[0031] In order to achieve the eddy current phenomenon of water to precipitate the sand and gravel in the water, refer to Figure 5 and Figure 8 It can be seen that an included angle is formed at the connection between the first baffle 6 and the baffle 7.

[0032] In order to improve the filtration of sand and gravel in the groove 4 in area a, specifically refer to Figure 5 It can be seen that the first diversion plate 9 is arranged in a semi-circular arc shape, and both ends of the first diversion plate 9 do not contact the convex strip and the side wall of the groove 4. Moreover, an arc-shaped protrusion is provided on the rear end surface of the first diversion plate 9, and the end of the protrusion faces the opening on the surface of the second baffle 10. One end of the second baffle 10 is fixedly connected to one side of the convex strip, and the other end is fixedly connected to the side wall of the groove 4. The water flow is divided into two parts of flow directions through the first diversion plate 9 and flows towards the front side of the second baffle 10. At this time, the included angle between the second baffle 10 and the side wall of the groove 4 causes the water flow to form an eddy current phenomenon, thereby realizing the precipitation of sand and gravel in the water, and then flowing reversely towards the arc-shaped protrusion. Through the action of the arc surface, the water flow changes direction and flows towards the opening. When flowing towards the arc-shaped protrusion, part of the water flow will flow into the second filter tank 12 for further precipitation.

[0033] Among them, refer to Figure 5 It can be seen that the radius of the first diversion plate is smaller than the radius of the second baffle 10, and both ends of the second baffle 10 form an included angle. Such a setting can realize the change of the water flow direction and the impact of the water flow, and realize the eddy current phenomenon.

[0034] In order to facilitate the water in the drip irrigation tape to enter area b, specifically refer to Figure 3 It can be seen that the water inlet 5 is arranged at an inclination angle of 45°.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
