Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of irrigation equipment, and in particular to a water-saving irrigation structure. BACKGROUND

[0002] Hill or hilly land is a terrain with a height difference between plains and mountains, and is formed by numerous small hills. Considering the complexity of the hilly terrain, additional consideration is also needed for water pressure pressurization and other needs. The equipment of the traditional pipe irrigation method is complex. At the same time, due to the water resource shortage in dry farming areas, even if there is water conservancy infrastructure, its role is relatively limited.

[0003] The water-saving device for hilly land irrigation disclosed in the publication No. CN221152331U includes a water storage tank and a water supplement tank located at the top of the water storage tank. The top of the water supplement tank is open. The bottom wall of the water supplement tank is provided with a water leakage hole communicating with the water storage tank. The water entering the water supplement tank flows into the water storage tank through the water leakage hole and is stored in the water storage tank. The bottom side of the water storage tank extends a plurality of irrigation pipes. Each irrigation pipe is in communication with the inside of the water storage tank. The side of the irrigation pipe facing the ground is provided with a first irrigation micro-pore. The water in the water storage tank can penetrate into the soil near the crop root system through the first irrigation micro-pore to achieve irrigation and water saving.

[0004] However, due to the open top of the water supplement tank for easy collection of rainwater, a large amount of dirt, sand and other impurities can accumulate in the water supplement tank over a long period of time. The impurities flow into the water storage tank through the water leakage hole. Over a long period of time, the impurities can easily block the first irrigation micro-pore on the irrigation pipe, ultimately reducing the irrigation effect of the water supplement tank on the soil. Content of the utility model

[0005] In order to reduce the blocking probability of the irrigation micro-pore over a long period of time, the present application provides a water-saving irrigation structure.

[0006] The water-saving irrigation structure provided by the present application adopts the following technical solution:

[0007] A water-saving irrigation structure includes a water storage tank and a water supplement tank located at the top of the water storage tank. The top of the water supplement tank is open. A filter element for preliminary filtering of rainwater is arranged in the water supplement tank. A drain pipe for discharging the rainwater after preliminary filtering into the water storage tank is arranged on the water supplement tank. A separation assembly for re-separating impurities in the drain pipe is arranged in the water storage tank. The separation assembly includes:

[0008] A cyclone separator is arranged on the water storage tank. The water inlet end of the cyclone separator is in communication with the drain pipe.

[0009] A water outlet pipe is arranged on the water outlet end of the cyclone separator and is in communication with the inside of the water storage tank.

[0010] A filter screen is installed at the outlet end of the hydrocyclone separator and is used to filter the water discharged from the hydrocyclone separator.

[0011] By adopting the above technical solution, the filter element performs preliminary filtration of the rainwater in the water supply tank. Then, the drain pipe discharges the pre-filtered rainwater into the hydrocyclone separator. The rainwater rotates in the hydrocyclone separator, causing larger impurities in the rainwater to collide with the side wall of the hydrocyclone separator under the action of centrifugal force and eventually slide into the bottom of the hydrocyclone separator. At the same time, the filter screen further filters the rainwater entering the outlet pipe, thereby reducing the content of impurities entering the water storage tank and reducing the probability of clogging of the irrigation micropores during long-term use.

[0012] Furthermore, the water storage tank is equipped with a cleaning component for automatically cleaning the filter screen, the cleaning component comprising:

[0013] A rotating rod is rotatably mounted on a water storage tank, and the rotating rod extends through a filter screen into a hydrocyclone separator;

[0014] Worm gear blades, which are mounted on a rotating rod and located inside the cyclone separator;

[0015] A scraper assembly is mounted on a rotating rod and pressed against the filter screen. The scraper assembly rotates with the rotating rod and cleans the filter screen.

[0016] By adopting the above technical solution, the rainwater discharged from the drain pipe drives the liquid inside the hydrocyclone separator to rotate. The rotating fluid drives the rotating rod to rotate through the worm gear blades, so that the scraper cleans the bottom of the filter screen, thereby reducing the probability of filter screen clogging.

[0017] Furthermore, the scraper component includes:

[0018] The mounting plate is mounted on the rotating rod and rotates with the rotating rod. The mounting plate has a mounting groove on the side near the filter screen.

[0019] A scraper blade, which is slidably disposed in a mounting groove and abuts against the filter screen;

[0020] A compression spring is provided in the mounting groove and is used to push the scraper blade toward the direction of the filter screen.

[0021] By adopting the above technical solution, the mounting plate rotates with the rotating rod, and the compression spring pushes the scraper to press against the bottom of the filter screen, so that the scraper and the filter screen are always pressed together, thereby ensuring that the scraper has a good scraping effect on the filter screen.

[0022] Furthermore, a cleaning brush is provided on the rotating rod, and the cleaning brush and the scraper are spaced apart at the same height on the rotating rod. The cleaning brush has bristles on the side near the filter screen for brushing the filter screen.

[0023] By adopting the above technical solution, the filter screen is brushed and cleaned by a cleaning brush with bristles, thereby cleaning the filter screen pores. The surface of the filter screen is scraped by a scraper. The cleaning brush and scraper work together to improve the cleaning effect of the filter screen.

[0024] Furthermore, the cyclone separator is detachably equipped with a collection box for collecting impurities.

[0025] By adopting the above technical solution, the impurities separated in the hydrocyclone separator are collected by the collection box, and the collection box is periodically removed and the impurities inside are cleaned.

[0026] Furthermore, the bottom of the water supply tank has an inverted conical structure, the drain pipe is located at the bottom of the inverted conical structure, and the filter element includes multiple sets of filter rings coaxially arranged on the bottom of the water supply tank for multi-stage filtration of the water entering the drain pipe. The height of the multiple sets of filter rings is lower than the internal height of the water supply tank, which facilitates some rainwater in the water supply tank to pass over the filter rings and enter the drain pipe.

[0027] By adopting the above technical solution, the bottom of the inverted cone-shaped water tank facilitates the guidance of rainwater to the drain pipe and timely discharge. Multiple sets of filter rings perform multi-stage filtration of the rainwater entering the drain pipe, reducing the impurity content of the rainwater entering the inlet pipe. At the same time, when the amount of rainwater in the water tank is large or the filter rings are clogged, the rainwater in the water tank can pass through the filter rings and enter the water supply pipe after it reaches a certain amount, thereby reducing the probability of rainwater being prevented from entering the drain pipe when the filter rings are clogged.

[0028] Furthermore, a guide top is provided on the top of the water replenishment tank. The guide top has a conical structure and is used to guide the water entering the water replenishment tank to the outermost filter ring.

[0029] By adopting the above technical solution, the guide top directs the rainwater entering the water supply tank to the outermost filter ring, thereby facilitating the rainwater to enter the drain pipe after being filtered through multiple sets of filter rings.

[0030] Furthermore, a float valve is installed on the water outlet pipe. The float valve floats on the water surface in the water storage tank and is used to control the opening and closing of the water outlet pipe.

[0031] By adopting the above technical solution, when the water storage tank reaches the set value, the float valve closes the outlet pipe, thereby allowing rainwater to be temporarily stored in the water replenishment tank.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. The rainwater in the water supply tank is initially filtered through a multi-stage filter ring. Then, the drain pipe discharges the initially filtered rainwater into the hydrocyclone separator. The rainwater rotates in the hydrocyclone separator, causing larger impurities in the rainwater to collide with the side wall of the hydrocyclone separator under the action of centrifugal force. Finally, they slide into the bottom of the hydrocyclone separator and are collected by the collection box. At the same time, the filter screen filters the rainwater entering the outlet pipe again, thereby reducing the content of impurities entering the water storage tank and reducing the probability of clogging of the irrigation micropores during long-term use.

[0034] 2. Rainwater discharged through the drain pipe drives the liquid inside the hydrocyclone separator to rotate. The rotating fluid drives the rotating rod to rotate through the worm gear blades, which causes the scraper and cleaning brush to clean the bottom of the filter screen, thereby reducing the probability of filter screen clogging.

[0041] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0042] This application discloses a water-saving irrigation structure.

[0043] Reference Figure 1 and Figure 2A water-saving irrigation structure includes a water storage tank 1 and a replenishment tank 2 located on top of the water storage tank 1. The top of the replenishment tank 2 is open. A filter element 3 for preliminary filtration of rainwater is installed inside the replenishment tank 2. A drain pipe 22 is installed on the replenishment tank 2 to discharge the pre-filtered rainwater into the water storage tank 1. A separation component 4 is installed inside the water storage tank 1 to further separate impurities within the drain pipe 22.

[0044] Reference Figure 1 The top of the water tank 2 is open to facilitate the collection of external rainwater. To reduce the probability of larger impurities entering the water tank 2, a screen 21 is fixedly installed on the top of the water tank 2 to initially block larger impurities. The bottom of the water tank 2 has an inverted conical structure, and the drain pipe 22 is fixedly installed on the bottom of the inverted conical structure to facilitate the timely drainage of water accumulated in the water tank 2 into the drain pipe 22. The filter element 3 consists of multiple sets of filter rings 31 coaxially fixedly installed on the bottom of the water tank 2. The multiple sets of filter rings 31 are used for multi-stage filtration of the water entering the drain pipe 22. The pore size of the multiple sets of filter rings 31 is smaller the closer they are to the drain pipe 22. The height of the multiple sets of filter rings 31 is lower than the height of the water tank 2. When the amount of rainwater in the water tank 2 is large or the filter rings 31 are blocked, the rainwater in the water tank 2 can pass through the filter rings 31 and enter the water tank 2 after a certain amount is measured, thereby reducing the probability of rainwater being prevented from entering the drain pipe 22 when the filter rings 31 are blocked.

[0045] Reference Figure 2 A guide top 23 is fixedly installed on the top of the water supply tank 2. The guide top 23 has a conical structure and is used to guide the rainwater entering the water supply tank 2 to the outside of the outermost filter ring 31. This allows the rainwater entering the water supply tank 2 to be filtered through multiple sets of filter rings 31, thereby improving the filtration effect of rainwater in the water supply tank 2 and reducing the impurity content entering the drain pipe 22.

[0046] Reference Figure 2 , Figure 3 and Figure 4The separation component 4 includes a hydrocyclone separator 41, a water outlet pipe 42, and a filter screen 43. The hydrocyclone separator 41 is fixedly installed on the water storage tank 1. The water inlet of the hydrocyclone separator 41 is connected to the inside of the drain pipe 22, so that the water discharged from the drain pipe 22 flows into the hydrocyclone separator 41 tangentially, causing the water entering the hydrocyclone separator 41 to rotate. This causes the impurities in the water to collide with the side wall of the hydrocyclone separator 41 under the action of centrifugal force, and finally slide down the side wall of the hydrocyclone separator 41 to the bottom. The bottom of the hydrocyclone separator has a conical structure to collect the impurities in the hydrocyclone. At the same time, a collection box 5 is detachably installed at the bottom of the hydrocyclone separator 41 by threads. The collection box 5 is used to collect the impurities settled in the hydrocyclone separator 41, and the collection box 5 is removed periodically to discharge the impurities inside.

[0047] Reference Figure 2 and Figure 4 The water outlet pipe 42 is fixedly installed on the water outlet end of the hydrocyclone separator 41. The water outlet pipe 42 is connected to the inside of the water storage tank 1, so that the water discharged from the hydrocyclone separator 41 is discharged into the water storage tank 1 for storage. In order to avoid the water volume in the water storage tank 1 being too large, a float valve 421 is fixedly installed on the water outlet pipe 42. The float valve 421 floats on the water surface of the water storage tank 1 and is used to control the opening or closing of the water outlet pipe 42. When the water volume in the water storage tank 1 reaches the set value, the float valve 421 closes the water outlet pipe 42, so that the rainwater is temporarily stored in the water replenishment tank 2. The filter screen 43 is fixedly installed on the water outlet end of the hydrocyclone separator 41. The filter screen 43 is used to filter the water discharged from the hydrocyclone separator 41, so as to reduce the probability of impurities entering the water storage tank 1.

[0048] Reference Figure 3 and Figure 4The water storage tank 1 is equipped with a cleaning component 6 for automatically cleaning the filter screen 43. This cleaning component 6 reduces the probability of the filter screen 43 becoming clogged due to impurities accumulated over long-term use. The cleaning component 6 includes a rotating rod 61, a worm gear blade 62, and a scraper 7. The rotating rod 61 is rotatably mounted on the water storage tank 1, extending through the filter screen 43 into the cyclone separator, with the center line of the rotating rod 61 coinciding with that of the filter screen 43. The worm gear blade 62 is fixedly mounted on the rotating rod 61 and is located inside the cyclone separator 41. When the water flow inside the cyclone separator 41 rotates, the worm gear blade 62 drives the rotating rod 61 to rotate. The scraper 7 is mounted on the rotating rod 61 and presses against the bottom of the filter screen 43. The scraper 7 rotates with the rotating rod 61 and cleans the bottom of the filter screen 43. The part is rotated for cleaning. The scraper component 7 includes a mounting plate 71, a scraper blade 72, and a compression spring 73. One end of the mounting plate 71 is fixedly mounted on the side wall of the rotating rod 61. The mounting plate 71 rotates with the rotating rod 61. A mounting groove 711 is opened on the end of the mounting plate 71 near the filter screen 43. The scraper blade 72 is slidably mounted in the mounting groove 711 and abuts against the filter screen 43. The compression spring 73 is fixedly mounted on the bottom of the mounting groove 711. The compression spring 73 is used to push the scraper blade 72 to move closer to the filter screen 43, so that the scraper blade 72 is always abutting against the bottom of the filter screen 43.

[0049] Reference Figure 4 In order to improve the cleaning effect on the filter screen 43, a cleaning brush 8 is also fixedly installed on the rotating rod 61. The cleaning brush 8 and the scraper are installed at the same height on the rotating rod 61 at intervals. The cleaning brush 8 has bristles fixedly installed on the side of the filter screen 43 near the filter screen 43 for brushing the filter screen 43. In this embodiment, the cleaning brush 8 and the scraper 7 are installed on the rotating rod 61 at a distance of 180 degrees.

[0050] Reference Figure 1 The water storage tank 1 is provided with a protruding section 11 that protrudes from the water replenishment tank 2. The top of the protruding section 11 has an opening, which facilitates cleaning of the inside of the water storage tank 1. A cover 12 is fixedly installed on the protruding section 11 to seal the opening. There is a certain gap between the cover 12 and the opening, which allows excess gas in the water storage tank 1 to be discharged through the gap between the cover 12 and the opening. An observation window 14 is provided on the side wall of the water storage tank 1, which facilitates observation of the water level in the water storage tank 1.

[0051] Reference Figure 1 and Figure 5 Multiple sets of irrigation pipes 13 are fixedly installed on the side wall near the bottom of the water storage tank 1. Multiple sets of irrigation microholes 131 are opened at intervals on the bottom of the water storage tank 1 and the bottom of the multiple sets of irrigation pipes 13 for slowly permeating the water accumulated in the water storage tank 1 into the soil.

[0052] Reference Figures 1-5The rainwater entering the water supply tank 2 is initially filtered by the screen 21 to prevent larger impurities from entering. Then, the rainwater is guided by the guide top 23 into the outermost filter ring 31. This multi-stage filtration by multiple filter rings 31 reduces the impurity content entering the drain pipe 22. Furthermore, when the water supply tank 2 is heavy or the filter rings 31 are clogged, the rainwater can bypass the filter rings 31 and enter the next stage of filter rings, further reducing the probability of clogging and facilitating timely storage in the water storage tank 1. When the drain pipe 22 discharges the rainwater from the water supply tank 2 into the cyclone separator 41, the tangential flow of the rainwater causes the liquid flow within the cyclone separator 41 to rotate. This causes impurities in the rainwater to impact the side wall of the cyclone separator 41 under centrifugal force, eventually sliding down the side wall into the collection box 5. Meanwhile, the filter screen 43 filters the separated rainwater again, and finally discharges it into the water storage tank 1 through the outlet pipe 42 for storage, so that the impurity content in the water storage tank 1 is low, reducing the probability of impurities clogging the irrigation micropores 131; when the water volume in the water storage tank 1 reaches the set value, the float valve 421 closes the outlet pipe 42, so that the excess rainwater is temporarily stored in the water replenishment tank 2; when the rainwater discharged from the drain pipe 22 drives the liquid in the cyclone separator 41 to rotate, the rotating fluid drives the rotating rod 61 to rotate through the worm gear blades 62, so that the scraper 72 and the cleaning brush 8 clean the bottom of the filter screen 43, thereby reducing the probability of the filter screen 43 clogging.

[0053] The working principle of this application embodiment is as follows:

[0054] The rainwater in the water supply tank 2 is initially filtered by the multi-stage filter ring 31. Then, the drain pipe 22 discharges the initially filtered rainwater into the cyclone separator 41. The rainwater rotates in the cyclone separator 41, causing larger impurities in the rainwater to collide with the side wall of the cyclone separator 41 under the action of centrifugal force. Finally, they slide into the bottom of the cyclone separator 41 and are collected by the collection box 5. At the same time, the filter screen 43 filters the rainwater entering the outlet pipe 42 again, thereby reducing the content of impurities entering the water storage tank 1 and reducing the probability of clogging of the irrigation micropores 131 during long-term use.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
