Description

Technical Field

[0001] The invention relates to an irrigation system, and more particularly to an irrigation system for collecting and filtering rainwater. Background Art

[0003] Irrigation is a difficult problem to solve when planting in mountainous areas. For example, when planting yam, yam has a high requirement for water, but yam is mostly planted in the mountains, where it is difficult to store water, and most farmers basically rely on the weather for harvest. Generally speaking, the rainy season in the south is relatively long, and yam can basically meet its growth needs with rainwater during its growth period. However, in recent years, there have been many abnormal weather phenomena. One year, there was almost no rain throughout the summer, and the weather was too dry, resulting in a significant decrease in yam yield and quality. In order to avoid the impact of abnormal weather, collecting rainwater for use in drought is an effective solution, but the existing rainwater collection methods mostly let the rainwater fall to the ground on rainy days and let it naturally gather in low-lying areas before being collected. There will be a lot of impurities (dead branches, rotten leaves, weeds, mud, etc.) mixed in, which is not convenient for direct irrigation. Summary of the invention

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] Reference Figure 1-6 As shown, a rainwater collection and filtration irrigation system includes a controller 1, a collection device 2 for collecting rainwater, a water inlet device 3 for extracting rainwater, a water storage device 4 for accumulating rainwater and a water supply device 5 for water supply irrigation, the water inlet device 3 is equipped with a water pump 32 for pumping water and a first filtering mechanism 31 for coarse filtering, the water supply device 5 is equipped with a second filtering mechanism 51 for secondary filtering and a water supply mechanism 52 for water supply, the second filtering mechanism 51 includes an arc tube 57, a first electric valve 571 is installed at the water inlet end of the arc tube 57, a second filter core 511 is installed at the water outlet end of the arc tube 57, the second filter core 511 is connected to a return pipe 572, a waste outlet 573 is installed at the bottom of the arc tube 57, the waste outlet 573 is detachably connected to a second electric valve 574, the second electric valve 574 is connected to a waste outlet pipe 575, the water pump 32, the first electric valve 571 and the second electric valve 574 are all electrically connected to the controller 1.

[0021] Through the above scheme, the controller 1 sets the preset water volume. When it rains, the rainwater flowing down from the mountain will accumulate in the collection device 2 to a sufficient amount of water, and the water pump 32 will be started to extract the water in the collection device 2, and remove impurities through the first filtering mechanism 31 to prevent dead branches, rotten leaves, weeds, mud, etc. from mixing in. The rainwater after the first filtration enters the water storage device 4 for storage to prevent evaporation and loss, and precipitates fine impurities that cannot be filtered in the water storage device 4. When the weather is continuously dry and irrigation is required, the water supply device 5 will filter the water in the water storage device 4 for the second time through the second filtering mechanism 51 and then provide it to the water supply mechanism 52 for use, ensuring that the supplied water quality can be directly used for drip irrigation, and it is not easy to be blocked by impurities.

[0022] In order to prevent the second filter mechanism 51 from being blocked, or to enable self-cleaning when blocked, since drip irrigation is used, the water supply is relatively low, and the inverted arc tube 57 allows the filtered impurities to accumulate at the arc-shaped bottom waste outlet 573, which is not easy to be blocked. The second electric valve 574 is opened regularly to discharge waste water mixed with impurities to ensure long-term operation. Even when the water supply device 5 is blocked, the controller 1 can control the first electric valve 571 to close to avoid the backflow of impurities, and the second electric valve 574 is opened to smoothly discharge the waste water mixed with impurities. A return pump or other mechanism that can return water is installed on the return pipe 572 to return the water flow to flush the second filter element 511. After self-cleaning is completed, the first electric valve 571 is opened and the second electric valve 574 is closed. The device can be operated again, reducing maintenance requirements and can operate for a long time.

[0023] As an improved specific implementation method, the water supply mechanism 52 includes a dripper 521, the dripper 521 is connected to a main valve 522, the main valve 522 is connected to a drip irrigation pipe 523, a plurality of branch valves 524 are installed on the drip irrigation pipe 523, the plurality of branch valves 524 are all connected to a branch pipe 54, the main valve 522 and the plurality of branch valves 524 are each provided with a flow monitoring sensor 525, the main valve 522, the branch valves 524 and the flow monitoring sensor 525 are all electrically connected to the controller 1.

[0024] Through the above scheme, the rainwater that has passed through the secondary filtration can be directly supplied to the drip irrigation device 521 for use, and the water flow of the main valve 522 and the multiple sub-valves 524 can be monitored by the flow monitoring sensor 525 to ensure stable water supply. The main valve 522 and the multiple sub-valves 524 are all electric valves, which are electrically connected to the controller 1, and can be used to regulate the water supply drip irrigation through the controller 1 to improve the utilization efficiency of water resources.

[0025] As an improved specific implementation method, the drip irrigator 521 is also connected to a water and fertilizer tank 53 for supplying water and fertilizer, and rainwater mixed with water and fertilizer can be drip-irrigated. The height of the water storage device 4 and the water and fertilizer tank 53 are both higher than the drip irrigator 521, reducing the water supply power of the drip irrigator 521, or using unpowered water supply drip irrigation through the height difference of mountain terrain. The water and fertilizer tank 53 is provided with a water and fertilizer detector 531 for monitoring the water and fertilizer content, a mixing valve 532 for mixing different water and fertilizers, and a plurality of water and fertilizer chambers 533 for accommodating non-water and fertilizer.

[0026] Through the above scheme, different water and fertilizer mixtures are mixed with rainwater for drip irrigation, which reduces the pressure of fertilization and improves planting efficiency.

[0027] As an improved specific implementation, the branch pipe 54 is connected to a shallow growth groove 541 for guiding the directional growth of yam. A drip pipe 542 is arranged in the shallow growth groove 541. The drip pipe 542 is provided with multiple drip holes 543. The tail end of the drip pipe 542 is closed.

[0028] Through the above solution, the built-in drip irrigation technology can directly provide the yam with water and utilize water resources with maximum efficiency.

[0029] As an improved specific implementation, the shallow soil trough 541 is also equipped with a humidity sensor 544 for monitoring soil humidity, and the humidity sensor 544 is electrically connected to the controller 1.

[0030] Through the above solution, the humidity sensor 544 monitors the soil humidity in real time, and the controller 1 maintains the soil humidity within a preset range based on the feedback.

[0031] As an improved specific implementation method, the water inlet device 3 includes a water inlet pipe 33, the water supply device 5 includes a water supply pipe 55, the water pump 32 is installed on the water inlet pipe 33, the water storage device 4 includes a water storage tank 42, and the water storage tank 42 is provided with a water inlet 421 and a water supply port 422, the water inlet 421 is arranged at the top of the water storage tank 42, the water supply port 422 is arranged at the bottom of the water storage tank 42, the water inlet 421 is used to connect with the water inlet pipe 33, the water inlet pipe 33 is installed with a water inlet sensor 34 for monitoring the water inlet amount, the water supply port 422 is used to connect with the water supply pipe 55, the water supply pipe 55 is installed with a water supply sensor 56 for monitoring the water supply amount, and the water inlet sensor 34 and the water supply sensor 56 are both electrically connected to the controller 1.

[0032] Through the above scheme, the water inlet and water outlet of the water storage tank 42 are monitored in real time through the water inlet sensor 34 and the water supply sensor 56 to ensure stable water storage.

[0033] As an improved specific implementation method, the collection device 2 is equipped with a rainwater sensor 21 electrically connected to the controller 1, a float plate 441 is installed in the water tank 42, and a water storage monitor 41 electrically connected to the controller 1 is installed on the float plate 441 for monitoring the water level. When the rainwater sensor 21 senses that the rainwater in the collection device 2 reaches a preset amount of water, the controller 1 controls the water pump 32 to start until the water flow in the collection device 2 drops to a preset value or the water storage monitor 41 senses that the water storage amount in the water storage device 4 reaches a preset target, and then the water pump 32 stops working.

[0034] Through the above scheme, when the water flow in the collection device 2 drops to the preset value, it means that the rain has stopped, the rainwater is insufficient, and water can no longer be stored. When the water storage monitor 41 senses that the water storage amount in the water storage device 4 has reached the preset target, it means that the water storage amount has reached the maximum amount that can be accumulated in the system, and no more water storage work is required. Through the automatic water storage of the controller 1, the system automatically operates, ensuring that rainwater can be maximized and avoiding the risk of manual operation errors.

[0035] As an improved specific embodiment, the collecting device 2 includes a collecting pool 22, in which a filtering pool 23 for filtering branches and dead leaves, a separation pool 24 for separating mud and sand, a sedimentation pool 25 for precipitating impurities, and a reservoir 26 for accumulating rainwater are arranged, and a rainwater sensor 21 is installed in the reservoir 26.

[0036] Through the above scheme, the rainwater entering the water reservoir 26 undergoes preliminary multiple filtrations, which can avoid the presence of excessive impurities and effectively reduce the filtering pressure of the first filtering mechanism 31.

[0037] As an improved specific implementation method, a collecting pipe 43 connected to the water supply pipe 55 through the water supply port 422 is also installed in the water storage tank 42, and the collecting pipe 43 is connected to the collecting head 44, and the collecting head 44 is installed on the floating plate 441, and the floating plate 441 is provided with a detection hole 442. The water storage monitor 41 is installed in the detection hole 442 and is provided with a sensing sheet 411.

[0038] Through the above scheme, the water level height can be monitored by the sensor to monitor the water storage in real time. When the water storage is completed, the upper end of the detection rod 45 will touch the top inner wall of the water storage tank 42, thereby driving the induction sheet 411 in the induction slot 451 to bend, and the water storage monitor 41 sends a signal of water storage completion to the controller 1. When the water level in the water storage tank 42 drops to the bottom, the upper end of the detection rod 45 will touch the bottom of the water storage tank 42, thereby driving the induction sheet 411 in the induction slot 451 to bend, and the water storage monitor 41 sends a signal of water exhaustion to the controller 1. The design of the floating plate 441 is to realize physical auxiliary monitoring of the two key water levels of the water volume to ensure the accuracy of the key signals.

[0039] As an improved specific embodiment, the first filter mechanism 31 is provided with a first filter element 311 and a first filter monitoring sensor 312 for monitoring the state and filtering effect of the first filter element 311, and the second filter mechanism 51 is provided with a second filter monitoring sensor 512 for monitoring the state and filtering effect of the second filter element 511.

[0040] Through the above solution, the first filter monitoring sensor 312 is electrically connected to the controller 1, and the first filter element 311 is ensured to filter normally through monitoring. The second filter monitoring sensor 512 is electrically connected to the controller 1, and the second filter element 511 is ensured to filter normally through monitoring.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
