[0001] The invention relates to the technical field of sub-membrane irrigation, and in particular to a farmland water conservation and water-saving sub-membrane drip irrigation water pipe connecting device. Background Art

[0002] In modern farmland water conservancy projects, sub-membrane drip irrigation is a common method of crop planting and cultivation. Its drip irrigation method is to connect multiple drip irrigation pipes, open drip irrigation ports on each branch pipe, and then use a connecting device to connect the drip irrigation pipes for fixed-point fertilization and irrigation of crops.

[0003] The existing drip irrigation pipe connection devices have a single function, such as water pipe connection elbows, male and female pipe joints, etc., which are mostly connected by hot melt or threaded male and female heads to connect the drip irrigation pipes to play the role of connecting branch pipes of drip irrigation water resources.

[0004] Drip irrigation pipes used under water-saving film for farmland irrigation have drip outlets on each branch pipe. The water inlet, through a connecting device, delivers water to each drip irrigation pipe. Water drips through the drip outlets to irrigate crops. Due to the small diameter of the drip outlets, the incoming water contains a high concentration of impurities and suspended matter, making it prone to clogging. Existing connection devices, whether using elbows to melt-connect the drip irrigation pipes or threaded male and female connectors, can only deliver water to each branch pipe and are prone to clogging the drip outlets of the drip irrigation pipes. Summary of the Invention

A plurality of separation tubes are arranged on the separation component of the present invention. Each separation tube is provided with a filtering component. The filtering is performed through a single tube in each separation tube, and the filtered impurities are accumulated in a separation chamber. Since the separation chamber and the sewage pipe are connected, when the impurities in the separation chamber accumulate to a certain amount, the valve of the sewage pipe is opened to discharge the water carrying a large amount of impurities, so as to reduce the problem of clogging of each separation tube. At the same time, the filtering of the drip irrigation water is achieved by the filtering component in each separation tube, thereby preventing the clogging of the drip irrigation port of the drip irrigation water pipe.

[0029] like Figure 1-Figure 5 As shown, the present embodiment discloses a water pipe connection device for drip irrigation under film for agricultural water conservation, including a separation component 1 and a sewage pipe 21. A separation chamber 12 is provided inside the separation component 1, and a plurality of separation pipes 11 are further provided on the separation component 1. Each separation pipe 11 is arranged circumferentially along the separation chamber 12 and is communicated with the separation chamber 12. The sewage pipe 21 is arranged below the separation chamber 12 and is communicated with the separation chamber 12. A valve 211 is provided on the sewage pipe 21, and a plurality of filter components 112 are provided in each separation pipe 11. The separation pipe 11 in the present embodiment is a PPR material pipe in the prior art. For example, Figure 1 As shown, the separation assembly 1 includes four separation tubes 11, each of which is arranged circumferentially along the separation chamber 12 and is connected to the separation chamber 12, so that each separation tube 11 can serve as a water inlet. The sewage pipe 21 is arranged below the separation chamber 12 and serves as a place for accumulating and discharging impurities filtered by the separation chamber 12. A valve 211 is provided on the sewage pipe 21 to facilitate regular cleaning. Each of the filter components 112 in this embodiment includes:

[0030] The filter plate 1121 is disposed inside the separation tube 11. The outer edge of the filter plate 1121 is fully fitted with the inner wall of the separation tube 11. The top of the filter plate 1121 is fixedly connected with a threaded column 11211.

[0031] The rotating impeller 1123 includes a rotating disk 11231, a power element 11212, and a plurality of rotating pieces 11232. The plurality of rotating pieces 11232 are fixed to the circumference of the rotating disk 11231. The rotating disk 11231 is connected to the output end of the power element 11212. The power element 11212 is fixed to the filter plate 1121.

[0032] The toggle switch 1124 is located outside the separation tube 11 and is connected to the end of the threaded column 11211 extending out of the separation tube 11 .

[0033] The filter component 112 of the water pipe connection device for water conservation under film drip irrigation in this embodiment includes: a filter plate 1121, a rotating impeller 1123 and a toggle switch 1124. Figure 1 As shown, the filter plate 1121 is arranged inside the separation tube 11, and the outer edge of the filter plate 1121 is fully matched with the inner wall of the separation tube 11 to ensure the sealing of the filter component 112 when filtering water. Figure 2 As shown, the top of the filter plate 1121 is fixedly connected with a threaded column 11211, as shown in FIG. Figure 4 As shown, the structural diagram of the power element 11212 of this embodiment is disclosed. The power element 11212 can be a motor, which is fixedly connected to the filter plate 1121. Figure 3 As shown, the filter membrane 1122 is fixed around the outer surface of the filter plate 1121 to block impurities in the water source. The rotating impeller 1123 includes a rotating disk 11231 and a plurality of rotating pieces 11232. The plurality of rotating pieces 11232 are fixed on the circumference of the rotating disk 11231. The rotating disk 11231 is connected to the output end of the power element 11212. When the power element 11212 rotates, it drives the rotating disk 11231 to rotate. When the rotating disk 11231 rotates, the rotating pieces 11231 rotate at the same time. Each rotating piece 11231 is close to one end of the filter membrane 1122, covering and contacting the filter membrane 1122, forming a scraping action for impurities accumulated on the filter membrane 1122, reducing the accumulation of impurities, improving the filtering performance of the device, ensuring the cleanliness of the water source inlet of the drip irrigation pipe, and thus reducing the blockage of the drip irrigation outlet.

[0034] Using the above technical solution of this embodiment, when connecting the drip irrigation pipe, the separation pipe 11, the separation chamber 12, the guide pipe 3 and the sewage pipe 21 are used as the whole device. Each separation pipe 11 is arranged along the circumference of the separation chamber 12 and is connected to the separation chamber 12. By twisting the toggle switch 1124 on the separation pipe 11, the filter plate 1121 connected thereto can be controlled, so that either end of the device can be used as the inlet of the drip irrigation water source. After the water source enters the separation pipe 11, the filter component 112 is fixed in the filter plate 112. The filter membrane 1122 on the outer surface of the filter plate 1121 intercepts impurities, suspended matter and other objects that are easy to clog the drip irrigation port from the incoming water source. At the same time, the rotation of the power element 11212 drives the rotating impeller 1123 to rotate. In addition, the impact force of the water source at the water inlet end on the rotating pieces 11232 on the rotating impeller 1123 enables the rotating impeller 1123 to rotate better underwater, and the rotating pieces 11232 scrape off the accumulated impurities generated by filtration on the filter membrane 1122.

[0035] As a preferred embodiment, a filter screen 23 is provided at the connection between the drain pipe 21 and the separation chamber 12. A slag discharge groove is provided on the inner wall of the separation pipe on the outer periphery of the water-facing surface of the filter plate 1121. The slag discharge groove is connected to the drain pipe 21 via a guide pipe 3. The guide pipe 3 is arranged at an angle, with the high end connected to the slag discharge groove and the low end connected to the drain pipe 21 between the filter screen 23 and the valve 211. After the accumulation reaches a saturated state, it is discharged into the guide pipe 3 through the slag discharge groove and flows into the drain pipe 21. The filter screen 23 can prevent large particles of impurities from entering the drain pipe 21 and entering the separation chamber 12, making the internal part of the device less prone to clogging. In this embodiment, the large particles of impurities filtered by the filter component 112 on the filter plate 1121 are accumulated in the slag discharge groove under the impact of the water flow on the upstream side. At the same time, the scraped impurities are accumulated in the center of the separation chamber 12 and enter the slag discharge groove under the impact of the incoming water flow. The impurities entering the slag discharge groove are inclined, and the high end is connected to the slag discharge groove, and the low end is connected to the guide pipe 3 on the sewage pipe 21 between the filter screen 23 and the valve 211. The large particles of impurities concentrated in the separation chamber 12 flow into the sewage pipe 21 through the guide pipe 3. As a preferred embodiment, an adsorption wheel 22 is provided under the sewage pipe 21. The adsorption wheel 22 simultaneously adsorbs impurities, so that the impurities are concentrated in the sewage pipe, which is convenient for cleaning after closing the valve 211, thereby improving the cleanliness of the water source in the drip irrigation pipe and ensuring the patency of the drip irrigation port of the drip irrigation pipe during drip irrigation of crops. A sealing plate can be provided at the bottom of the sewage pipe 21 so that when the amount of impurities is low, the adsorption wheel 22 can adsorb and accumulate impurities. When the amount of impurities increases, the sealing plate at the bottom is opened to discharge the impurities, thereby avoiding the problem of large water waste caused by the bottom of the sewage pipe 21 being always open. The discharged water containing impurities can be directly discharged into farmland for irrigation.

[0036] As a preferred embodiment, each rotating piece 11232 is designed to be bent at a 45° angle relative to the axis of the rotating disk 11231. The 45° bend of the rotating pieces 11232 allows the impact force of the water flow on the incoming surface to act on each rotating piece 11232, thereby minimizing the rotational resistance and effectively driving the rotating pieces 11232 to rotate.

[0037] Preferably, the plurality of rotating blades 11232 on the rotating impeller 1123 are provided with a flexible layer at one end near the circular surface of the filter plate 1121. During rotation, the plurality of rotating blades 11232 on the rotating impeller 1123 simultaneously scrape impurities from the filter membrane 1122 at one end near the circular surface of the filter plate 1121, thereby covering and contacting the filter membrane 1122. The flexible layer design reduces damage to the filter membrane 1122 and improves the durability of the filter membrane 1122.

[0038] Preferably, the blades on the adsorption wheel 22 are all made of activated carbon, and the projected area of ​​the wheel surface facing the water inlet direction covers the entire surface of the adsorption wheel 22. An activated carbon adsorption layer is provided on the blades covering the entire surface of the adsorption wheel 22, which can adsorb impurities in the sewage pipe 21 over a maximum area.

[0039] Preferably, the valve 211 is located between the lower end of the guide pipe 3 and the adsorption wheel 22. The valve 211 can be opened and closed to block the connection between the adsorption wheel 22 and the guide pipe 3, making it easier to clean impurities in the sewage pipe 21. The adsorption wheel 22 can be detachably connected to the sewage pipe 21, and closing the valve 211 also facilitates cleaning of the adsorption wheel 22.

[0040] Preferably, a filter membrane 1122 is fixedly connected to the outer surface of the filter plate 1121. The filter membrane 1122 is made of a hollow fiber ultrafiltration membrane. The hollow fiber tube wall of the hollow fiber ultrafiltration membrane is covered with micropores, which can block suspended matter and impurities in the water. It also has strong antioxidant properties, corrosion resistance, and is not easy to deform.

[0041] As a preferred embodiment, the separation tube 11, separation chamber 12, flow guide tube 3 and sewage pipe 21 are made of PPR material. Considering factors such as material cost, corrosion resistance, and toughness, PPR material is more suitable for this type of device.

[0042] The agricultural water conservancy and water-saving sub-membrane drip irrigation pipe connection device of this embodiment is provided with a separation component and a sewage pipe. The separation component is connected to the water supply pipeline and is used to separate impurities from the supplied water source. A plurality of separation tubes are provided on the separation component. Each separation tube is provided with a filtering component. The single tube in each separation tube is filtered, and the filtered impurities are accumulated in the separation chamber. Since the separation chamber and the sewage pipe are connected, when the impurities in the separation chamber accumulate to a certain amount, the water carrying a large amount of impurities is discharged by opening the valve of the sewage pipe to reduce the problem of clogging of each separation tube. At the same time, the filtering component in each separation tube also realizes the filtration of the drip irrigation water, thereby preventing the clogging of the drip irrigation port of the drip irrigation pipe.

[0043] The filter component of the present invention controls the water inlet end through a toggle switch threadedly connected to the threaded column on the filter plate, so that each separation tube can be connected to the water supply pipeline as a water inlet pipe. The filter plate is connected to a rotating disk, which rotates under the action of a power element fixed to the filter plate, and at the same time drives the rotating piece fixed on the outer surface of the rotating disk to rotate. When the drip irrigation water enters the separation tube, the filter component in each separation tube intercepts impurities and suspended matter, and the rotation of the rotating piece on the rotating impeller can scrape off impurities attached to the filter plate, thereby achieving filtration of the drip irrigation water quality and preventing clogging of the filter plate.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
