Description

Technical Field

[0001] The invention relates to agricultural irrigation facilities, in particular to a zero-power consumption automatic sprinkler irrigation system. Background Art

[0002] At present, the irrigation of crops is gradually tending towards regular and quantitative automatic irrigation. Generally, the regular and quantitative automatic irrigation equipment is costly and power-consuming, and is only suitable for large-scale farmland. Sprinkler irrigation is one of the energy-saving and water-saving irrigation methods. There are three main types of existing sprinkler devices: 1. Walking sprinkler irrigation equipment, 2. Winding sprinkler equipment, and 3. Underground sprinkler modules. Walking sprinkler irrigation equipment has a complex structure and is subject to geographical and environmental restrictions; winding sprinkler equipment requires equipment to be towed and transported during use, which causes many inconveniences during work; the underground sprinkler module is lifted by a special soil breaker and then the nozzle is replaced for irrigation, which requires a large water supply pressure. As for the above automatic irrigation, electric drive is often used, which greatly increases energy consumption, and there is no good energy-saving and environmentally friendly automatic irrigation device. Summary of the invention

[0003] The purpose of the present invention is to provide a zero-power consumption automatic sprinkler irrigation system, which can solve one or more of the above-mentioned technical problems.

[0004] In order to achieve the above object, the technical solution proposed by the present invention is as follows:

[0005] The zero-power automatic sprinkler irrigation system includes a water storage module, a timing module, a precipitation regulation module, and a water spray module in sequence according to the height difference.

[0006] The water storage module is connected to a first water outlet pipe, a flow rate regulator is installed on the first water outlet pipe, and a water outlet of the first water outlet pipe is communicated with the timing module.

[0007] The flow rate regulator can control the water flow rate, thereby controlling the time when the water flows into the timing module.

[0008] The timing module is a tilting device, which is lower than the water storage module. The tilting device is installed above the precipitation regulating module through a bracket, and the opening of the tilting device is directly opposite to the water outlet of the first water outlet pipe.

[0009] After the water collector has collected a certain amount of water, all the water inside will be poured into the water collecting bucket to achieve timed and quantitative irrigation.

[0010] The precipitation regulation module includes a water receiving bucket, a base, a cross bar, a water collecting trough, a support rod, a second water outlet pipe, and a drain pipe; the base is installed in the water receiving bucket, the cross bar is swingably installed on the base, the water collecting trough is installed at one end of the cross bar through the support rod, and the second water outlet pipe is fixed at the other end of the cross bar; the other end of the second water outlet pipe passes through the side wall of the water receiving bucket and goes out of the water receiving bucket to guide the water in the water receiving bucket into the water spray module; the drain pipe is installed at the bottom end of the water receiving bucket wall.

[0011] The second water outlet pipe enables the water in the water receiving bucket to flow out to the water spraying module. The second water outlet pipe is sealed between the wall of the water receiving bucket. The second water outlet pipe is a flexible conduit with an unlimited length. When the cross bar swings, it is ensured that the movement of the second water outlet pipe will not damage the seal between it and the wall of the water receiving bucket, ensuring that the wall of the water receiving bucket does not leak water.

[0012] The water discharged by the drain pipe can be stored in a water receiving container for later reuse, or directly discharged into a river, canal, etc. to the water storage module below.

[0013] The usage process of the precipitation adjustment module is as follows: During normal operation: The water in the second water outlet pipe uses the siphon principle to directly discharge the water in the water receiving bucket to the water spraying module; When the water receiving amount in the rainwater collection trough reaches a certain amount, the second water outlet pipe will tilt upward. After the tilting device pours water, the liquid level in the water receiving bucket is lower than the top end of the second water outlet pipe, and water will no longer be supplied to the water spraying module. The water in the water receiving bucket will slowly flow out from the drain pipe until it is emptied. When the water in the collection trough decreases due to evaporation, one end of the second water outlet pipe on the cross bar drops, and after the tilting device pours water, water is supplied to the water spraying module.

[0014] The diameter ratio between the second water outlet pipe and the drain pipe is not limited. The diameter of the drain pipe is much smaller than that of the second water outlet pipe, and it is adjusted according to actual irrigation needs.

[0015] The water spraying module includes a sprinkler pipe, a nozzle, and a sprinkler frame; A nozzle is provided at the front end of the sprinkler pipe. The nozzle includes a first pipe, a second pipe, and a through hole; The second pipe can telescopically move inside the first pipe without falling off. The front end of the second pipe is closed, and the through hole is opened on the side wall of the second pipe. The second pipe connects the sprinkler pipe and the first pipe so that the water in the sprinkler pipe is sprayed from the through hole; The sprinkler pipe is installed on the sprinkler frame through a rotating shaft. The nozzle faces upward (there are many ways for the nozzle to face upward here. For example, the bottom of the sprinkler pipe is heavier than the front end, so that the initial state of the sprinkler pipe is tilted backward; Or directly install the rotating shaft near the nozzle, making the weights at both ends of the rotating shaft different and naturally tilting); The sprinkler pipe is connected to the water receiving bucket through a conduit. Here, the upper end of the conduit is connected to the second water outlet pipe and then connected to the water receiving bucket; The conduit can be directly removed, and the second water outlet pipe can be directly connected to the sprinkler pipe.

[0016] The number of water spraying modules is not limited here. According to the actual situation, multiple water spraying modules can be set, and the spraying angles and positions of multiple water spraying modules are arranged and combined according to actual irrigation needs.

[0017] The sprinkler pipe is constantly filled with water. When the liquid level in the sprinkler pipe reaches a certain height, the sprinkler pipe will rotate and flip around the rotating shaft, and the second pipe will be thrown out, and the water in the sprinkler pipe will be sprayed out from the through hole.

[0018] The present invention mainly utilizes the gravitational potential energy of water to convert water into sprinkler pressure in the process of gradual outflow; a timing module and a precipitation regulation module are added during the sprinkler irrigation process, the timing module controls the rhythm and water volume of the sprinkler irrigation, and the precipitation regulation module adjusts the sprinkler irrigation according to precipitation and evaporation conditions.

[0019] The flow rate regulator in the present invention is a ball valve, a butterfly valve, or a flow rate regulating control switch, etc., which is not limited here.

[0020] Further: it also includes a precipitation adjustment counterweight module, the counterweight module includes an arc tube and a metal block; the arc tube is fixed on the cross bar with its opening upward, and the metal block rolls in the arc tube. Preferably, the lowest end of the arc tube and the swing point of the cross bar are arranged on the same vertical line. There is no limitation on whether the two ends of the arc tube 51 are open or closed, and it is best to be closed to prevent debris from entering and to prevent water from entering, while ensuring that the counterweight block does not separate.

[0021] A counterweight module is set in the precipitation regulation module. Through the movement of the center of gravity of the metal ball and the design of the curved arc, the starting conditions for the left and right tilting of the crossbar are different, so that there is a difference between the precipitation water level and the evaporation water level of the water collection tank.

[0022] Further: the metal block is a metal ball, which is convenient for rolling and smoother for adjustment.

[0023] Furthermore, the diameter of the second water outlet pipe is larger than the diameter of the drain pipe, which effectively ensures that the water in the water receiving bucket is mainly used for sprinkler irrigation.

[0024] Further: a rain shelter is arranged above the said device to prevent the influence of rainfall on the sprinkler irrigation time.

[0025] Further: the water storage module is a water source located at a high place (a reservoir, a river or a lake, etc.) or a water storage barrel located at a high place.

[0026] Further, it also includes a sprinkler irrigation bucket, which is lower than the water receiving bucket and higher than the sprinkler irrigation pipe; the sprinkler irrigation bucket receives water output from the second water outlet pipe; the bottom of the sprinkler irrigation bucket is connected to the sprinkler irrigation pipe through a conduit, and the conduit is connected between the rotating shaft and the sprinkler head.

[0027] Furthermore: a first annular protrusion is provided at the front end of the second tube, a second annular protrusion is provided at the rear end of the first tube, the first annular protrusion is located in front of the second annular protrusion to prevent the first tube from falling off from the second tube; a dynamic seal is provided between the first tube and the second tube.

[0028] The technical effects of the present invention are:

[0029] The present invention can realize timed and quantitative fully automatic watering with a long range. The precipitation regulation module can adjust irrigation according to rainfall, and self-pressure sprinkler irrigation is implemented by using the water drop. It does not consume electricity and does not require chemical energy. It has the advantages of saving labor, water and environmental protection. The equipment is low in cost and easy to use.

DETAILED DESCRIPTION

[0043] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, wherein the illustrative embodiments and descriptions are only used to explain the present invention but are not intended to be improper limitations of the present invention.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0046] The zero-power automatic sprinkler irrigation system includes a water storage module 1, a timing module 2, a precipitation adjustment module 3, and a water spray module 4 in sequence according to the height difference.

[0047] The water storage module 1 is connected to a first water outlet pipe 11, a flow rate regulator 12 is installed on the first water outlet pipe 11, and the water outlet of the first water outlet pipe 11 is connected to the timing module 2. The water storage module is a water source located at a high place (river reservoir or lake, etc.) or a water storage barrel located at a high place.

[0048] The timing module 2 is a tilting device, which is lower than the water storage module, and is installed above the precipitation adjustment module through a bracket, and the opening of the tilting device faces the outlet of the first outlet pipe. A rain shelter is arranged above the tilting device (not shown in the figure).

[0049] exist Figure 1The timing module 2 in it is a qì vessel. The qì vessel is a container with an open upper end. The side wall of the container can be hung with a rope (or axially connected to a bracket). The bottom of the container has uneven thickness (causing eccentricity and can be timed to turn over). Water drips evenly at the upper open end of the container. In addition, a rain shelter is placed above the qì vessel. When the device is not filled with water, it tilts slightly forward. After being filled with water, the tank body stands up a little. When it is full of water, the tank overturns, pours out the water, and then automatically restores to wait for watering again. This device can achieve timed and quantitative watering. The cycle can be 12 hours, 24 hours, 48 hours... The thickness of the pipe diameter and the capacity of the qì vessel control the watering frequency and the amount of water poured at one time. The flow rate regulator 12 here uses a flow rate adjustment control switch. The thickness of the pipe diameter is adjusted by a roller. During implementation, first select the qì vessel according to the amount of water poured at one time, and then adjust the flow rate regulator to select the corresponding flow rate. One overturn of the qì vessel is one cycle. The device can be adjusted according to needs (for example, plants are watered at 6 am and 6 pm in summer. Select a qì vessel with a 12-hour cycle and start uniform water dripping on it at 6 am on a certain day; plants are watered at 1 pm in winter. Select a qì vessel with a 24-hour cycle and start uniform water dripping on it at 1 pm on a certain day). It can also be equipped with two or more qì vessels (for example, water is watered twice a day, at 7 am and 5 pm. Select two qì vessels with a 24-hour cycle, numbered A and B respectively. A starts uniform water dripping on it at 7 am on a certain day, and B starts uniform water dripping on it at 5 pm on the same day. Since then, the device realizes automatic watering at 7 am and 5 pm every day. If you want the amount of water poured at 7 am to be more than that at 5 pm, then the capacity of A is larger and the diameter of the thin pipe on it is thicker).

[0050] As Figure 2 shown, the precipitation adjustment module 3 includes a water receiving bucket 31, a base 32, a cross bar 33, a water collecting trough 34, a support rod 35, a second water outlet pipe 36, and a drain pipe 37; the base is installed in the water receiving bucket, the cross bar 33 is swingably installed on the base 32, a water collecting trough 34 is installed at one end of the cross bar 33 through the support rod 35, the other end of the cross bar is fixed with the second water outlet pipe 36, and the second water outlet pipe 36 is attached to the cross bar 33; the other end of the second water outlet pipe 36 passes through the side wall of the water receiving bucket and extends outside the water receiving bucket to introduce the water in the water receiving bucket 31 into the spraying module; the drain pipe 37 is installed at the bottom end of the wall of the water receiving bucket 31. The opening where the second water outlet pipe 36 extends out of the wall of the water receiving bucket is the water outlet hole 38.

[0051] As Figure 3 shown, generally, after the qì vessel of the timing module 2 pours water, the water outlet hole 38 and the second water outlet pipe 36 are under the liquid level, the second water outlet pipe 36 stores water, and the second water outlet pipe 36 introduces the water into the spraying module 4. When the liquid level drops below the water outlet hole 38, because the second water outlet pipe 36 is full of water, this module continues to convey water;

[0052] As Figure 4As shown, in case of rainfall, when the water in the water collecting tank 34 reaches a certain amount, the crossbar swings, and the second water outlet pipe 36 is lifted and positioned above the liquid surface; after the water is poured out of the water collecting tank, the water cannot be delivered through the water outlet hole 38, and the water will slowly flow out from the drain pipe 37;

[0053] When the water in the water collection tank 34 is reduced to a certain extent due to evaporation (for example, the time required for evaporation of 10 mm of 20 mm precipitation varies from ten to several dozen hours depending on the temperature and wind speed), the second water outlet pipe 36 descends and supplies water to the water spray module 4 after the water is poured out of the water dispenser.

[0054] The precipitation regulating device can promote crop growth in accordance with climate change, so as not to over-water or under-water. The greater the rainfall, the longer the watering time will be stopped; the greater the evaporation, the shorter the time to resume watering.

[0055] It also includes a precipitation adjustment counterweight module 5, which includes an arc tube 51 and a metal block 52; the arc tube 51 is fixed on the cross bar 33 with its opening upward, and the metal block 52 rolls in the arc tube. The metal block 52 is a metal ball. The diameter of the second outlet pipe 36 is greater than that of the drain pipe 37.

[0056] In this module, by moving the center of gravity of the metal ball and designing the arc of the curved pipe, the starting conditions for the left and right tilting of the crossbar are different, so that there is a difference between the precipitation water level and the evaporation water level of the water collection tank 34.

[0057] like Figure 5 As shown, the water spray module 4 includes a sprinkler pipe 41, a nozzle 42, and a sprinkler frame 43; a nozzle is arranged at the front end of the sprinkler pipe, and the nozzle includes a first tube 421, a second tube 422, and a through hole 423; the second tube is retracted and does not fall off in the first tube, the front end of the second tube is closed, and the through hole is opened on the side wall of the second tube, and the second tube connects the sprinkler pipe and the first tube so that water in the sprinkler pipe can be sprayed from the through hole; the sprinkler pipe 41 is installed on the sprinkler frame 43 through a rotating shaft 44; the sprinkler pipe 41 is connected to the water receiving bucket 31 through a conduit 45.

[0058] It also includes a sprinkler bucket 46 , which is lower than the water receiving bucket 31 and higher than the sprinkler pipe 41 ; the sprinkler bucket 46 receives water output from the second water outlet pipe 36 ; and the bottom of the sprinkler bucket 46 is connected to the sprinkler pipe 41 through a conduit 45 .

[0059] The sprinkler pipe 41 is connected to the water receiving bucket 31 by a guide tube 45 and a sprinkler bucket 46 at the upper end or by a second water outlet pipe 36; the sprinkler pipe 41 is installed on the sprinkler frame 43 through a rotating shaft 44, and a nozzle 42 (retractable) is mounted on the front end, which retracts and retracts as the sprinkler pipe 41 swings back and forth. The device uses the center of gravity movement and lever balance to achieve long-range sprinkler irrigation. Before irrigation begins, Figure 6As shown, irrigation starts, water is injected into the device, the liquid level in the sprinkler barrel 46 rises, and the sprinkler head 42 itself is heavy enough and will not be pushed open at this time. When the liquid level reaches a certain height, the sprinkler pipe 41 swings forward and the sprinkler head 42 extends forward. Figure 7 After the irrigation is finished, the sprinkler pipe 41 swings back and the sprinkler head 42 retracts to restore to Figure 6 The higher the liquid level in the sprinkler barrel 46 is, the greater the initial velocity of the water when it is sprayed out, and thus the longer the range is.

[0060] A first annular protrusion 4221 is provided at the front end of the second tube 422, and a second annular protrusion 4211 is provided at the rear end of the first tube 421. The first annular protrusion is located in front of the second annular protrusion to prevent the first tube from falling out of the second tube; a dynamic seal is provided between the first tube and the second tube.

[0061] The present invention can be flexibly adjusted, and the following are several embodiments of flexible use.

[0062] Embodiment 1:

[0063] Here, the water storage module 1 is a high reservoir (generally speaking, the liquid level in the water storage module is maintained constant to ensure accurate watering time). The first water outlet pipe 11 draws water from the water storage module 1 using the siphon principle, and the flow rate regulator 12 adjusts the flow rate, so that the water in the first water outlet pipe 11 drips at a uniform speed above the timing module 2. When the water in the timing module 2 is full, it overturns and pours the water into the precipitation regulation module 3.

[0064] like Figure 3 As shown, in general, water from the precipitation regulating module 3 flows into the water spraying module 4 through the second water outlet pipe 36 for irrigation;

[0065] like Figure 4 As shown, shortly after the rainfall, water from the precipitation regulating module 3 flows into the water container 6 through the drainage pipe 37; the water container 6 can be a low-lying reservoir, a river, etc.

[0066] If fertilization is required, a water storage container is set between the water storage module and the first water outlet pipe. Diluted fertilizer is placed in the water storage container to achieve automatic fertilization. The water in the water container 6 can be manually poured back into the water storage container at any time.

[0067] If the plants require a lot of water, such as trees and tall plants, or the area is windy and sunny and not suitable for sprinkler irrigation, the sprinkler module 4 can be omitted, and the second water outlet pipe 36 can be placed near the roots of the plants for direct irrigation.

[0068] Embodiment 2:

[0069] Used for watering indoor plants and flowers or in arid areas, the water storage module 1 is a water storage container (the liquid level in the water storage container is maintained constant to ensure accurate watering time) or tap water, the precipitation regulation module 3 and the water container 6 are omitted, the timing module 2 pours water into the sprinkler bucket 46, and the water flows into the sprinkler pipe 41.

[0070] In addition, the first water outlet pipe 11 can be connected to the top of the sprinkler barrel 46 (directly omitting the timing module 2, precipitation adjustment module 3, and water container 6 in the middle), and the flow rate regulator 12 adjusts the flow rate to drip water at a uniform speed above the sprinkler barrel 46. When the liquid level in the sprinkler barrel 46 reaches a certain height, the sprinkler pipe 41 flips forward to perform sprinkler irrigation, and resumes after the sprinkler irrigation is completed. The sprinkler barrel 46 and the sprinkler pipe 41 are adjusted periodically according to specific irrigation needs. During sprinkler irrigation, as the liquid level in the sprinkler barrel 46 drops, the range is from far to near.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
