Description

Technical Field

[0001] The present invention relates to a new siphon water conveyance system and its usage method, belonging to the technical field of farmland water conservancy. Background Art

[0002] Irrigation of fields along the Yellow River by diverting the water from the elevated river usually requires huge investments in building drainage and irrigation stations. In the case of reclaiming fields from lakes, the fields reclaimed for irrigation can only use motor pumps to extract lake water for irrigation due to the interception by dams, resulting in high energy consumption and a small range of water flow regulation. For fields with different water flow requirements, the effect of water diversion for irrigation is poor and the efficiency is low; moreover, in the way of using motor pumps for extraction and irrigation, the outlet pipe is generally a thick pipe, and the water flow is relatively concentrated, which is likely to cause damage to crops due to long-term watering of the same position by a large water flow.

[0003] In addition, during the flood season, in order to prevent the key protected dike sections from bursting or overflowing, the dikes are usually blown up or dug up at the non-key protected dike sections to release flood water, which makes it impossible to control the size of the breach and easily leads to a large post-disaster reconstruction project.

[0004] For farmland and vegetable plots, wells are often dug to draw water for watering crops. Generally, very deep wells need to be dug to reach the water, which is time-consuming and laborious. And for low-lying farmland, draining rainwater usually requires digging ditches to drain into the river, which is time-consuming, laborious and occupies farmland area.

[0005] In the prior art, there are also some siphon irrigation devices or flood discharge devices that use the siphon principle to draw water out, reducing the energy consumption required for flood discharge or irrigation. For example, the utility model patent with the application number CN201020272476.8 discloses a siphon type simple gravity irrigation device, which mainly includes an exhaust device, an inlet pipe, an outlet pipe and a stop valve. The structure is relatively simple, and both the inlet pipe and the outlet pipe are conventional thick pipes, and there is also the problem that the water flow of the outlet pipe used by the above-mentioned motor pump is relatively concentrated;

[0006] The utility model patent with the application number CN201721463837.5 discloses a siphon type drainage and flood discharge device that can be quickly installed, including an inlet mechanism, a diversion mechanism, a first drain pipe, a second drain pipe and an outlet mechanism. Its first drain pipe and second drain pipe are also conventional thick pipes, and there is also the problem that the water flow of the outlet pipe used by the above-mentioned motor pump is relatively concentrated.

[0007] More importantly, the siphon effect requires that the air in the pipe be exhausted, but some siphon irrigation devices or flood discharge devices in the prior art mostly use a spliced ​​hard pipe structure, which occupies a large storage space when not in use and is not easy to move when needed. In addition, it cannot be laid over long distances during use, and the hard pipe must be connected and changed direction with a turning joint when the ground slope changes, which can easily lead to air leakage at the pipe connection and destroy the siphon effect; the device cannot be moved after it is fixed; in addition, the drainage pipe and water inlet pipe used in the device are non-transparent pipes, and the accumulation in the pipe cannot be checked in real time during use. Gas situation: when a lot of gas accumulates in the pipe and is not discharged in time, it will also affect the normal operation of the siphon effect. In addition, the siphon body used in the existing device is generally directly arranged on the pipe, and its volume is small, which leads to the siphon body being prone to tilting or falling during use. Once the siphon body tilts or falls, it will directly affect the normal operation of the siphon effect. In order to avoid its tilt, the prior art often needs to separately set up a corresponding structure to fix the siphon body, which increases the cumbersomeness of use and the complexity of the structure of the device to a certain extent, and also increases the manufacturing cost of the device.

[0008] Therefore, there is an urgent need for a new type of low-energy or zero-energy, portable siphon water delivery system that is suitable for both farmland irrigation and flood discharge and drainage. Summary of the invention

[0009] The present invention aims to solve the problems that the existing siphon device is easily affected by air leakage in the pipeline or the gas in the pipeline is not discharged in time, which affects the normal siphon effect and thus affects the irrigation or flood discharge efficiency, and the existing siphon device is a hard pipe that is inconvenient to carry and cannot be moved, thereby providing a new siphon water delivery system and a method of use.

[0010] The technical solution adopted by the present invention to solve the above technical problems is:

[0011] A new type of siphon water delivery system includes a siphon tower, a filter cage, a water inlet manifold, a plurality of water inlet pipes and a plurality of water outlet pipes, wherein:

[0012] One end of a plurality of water inlet pipes and one end of a plurality of water outlet pipes are respectively connected to the water inlet side and the water outlet side of the siphon pagoda.

[0013] The other ends of the several water inlet pipes are connected to the water inlet manifold.

[0014] The water inlet manifold is provided with a first valve.

[0015] A second valve is installed at the other end of each water outlet pipe.

[0016] The filter cage is connected to the water inlet side of the water inlet manifold.

[0017] The siphon pagoda includes a siphon main body and an exhaust chamber connected to the top of the siphon main body. A third valve and a fourth valve are respectively arranged at the top inlet and the bottom outlet of the exhaust chamber.

[0018] The siphon pagoda is a visible structure, and each water inlet pipe and each water outlet pipe are visible flexible hoses.

[0019] Further, the other ends of a plurality of water outlet pipes are all connected to a water outlet water distributor, and a fifth valve is arranged on the water outlet water distributor.

[0020] Further, the outlet end of the water outlet water distributor is connected with a water outlet elbow, and the water outlet of the water outlet elbow is arranged upward.

[0021] Further, a plurality of first water inlet connecting pipes are connected to the water inlet side of the siphon pagoda in a communicating way, a plurality of first water outlet connecting pipes are connected to the water outlet side of the siphon pagoda in a communicating way, a plurality of second water outlet connecting pipes are connected to the water outlet side of the water inlet water distributor in a communicating way. One ends of a plurality of water inlet pipes are hermetically communicated with a plurality of first water inlet connecting pipes correspondingly, the other ends of a plurality of water inlet pipes are hermetically communicated with a plurality of second water outlet connecting pipes correspondingly, and one ends of a plurality of water outlet pipes are hermetically communicated with a plurality of first water outlet connecting pipes correspondingly.

[0022] Further, the lengths of every two adjacent first water inlet connecting pipes are different, the lengths of every two adjacent first water outlet connecting pipes are different, and the lengths of every two adjacent second water outlet connecting pipes are different.

[0023] Further, a plurality of second water inlet connecting pipes are connected to the water inlet side of the water outlet water distributor in a communicating way, and the other ends of a plurality of water outlet pipes are hermetically communicated with a plurality of second water inlet connecting pipes correspondingly.

[0024] Further, the lengths of every two adjacent second water inlet connecting pipes are different.

[0025] Further, the filter cage includes a support frame and a filter screen sleeved outside the support frame, and the water inlet of the water inlet water distributor extends into the middle of the filter cage.

[0026] Further, the third valve is a quick-connect ball valve.

[0027] A method of using the above new siphon water conveyance system, by adjusting the positions of the water inlet and the water outlet of the siphon water conveyance system, making the siphon water conveyance system applicable to different water diversion requirements. Among them, when used to divert water from a high-level water source across a dam to a low-level water source, the water inlet of the new siphon water conveyance system is set higher than the water outlet of the new siphon water conveyance system; when used to divert water from a low-level water source across a bank to a dam field, a storage pool is dug in advance in the dam field, then the water inlet of the new siphon water conveyance system is set below the water surface of the low-level water source, and the water outlet of the new siphon water conveyance system is set in the storage pool and the water outlet is set lower than the water inlet; when used to drain the low-lying water in the field, first dig a pit pool at the deepest part of the low-lying water in the field, then place a water bucket on the slope of the river ditch on the other side of the dam, set the water inlet of the new siphon water conveyance system below the water level in the pit pool, and set the water outlet of the new siphon water conveyance system in the water bucket. When the water levels in the pit pool and the water bucket are level, the siphon pauses. When the water accumulation in the pit pool increases, the siphon starts automatically.

[0028] The present invention has the following effects compared with the prior art:

[0029] Each water inlet pipe and each water outlet pipe are both transparent or semi-transparent flexible hoses, making the siphon water conveyance system have the convenience of coiling and transporting, effectively overcoming the problem of inconvenient carrying and transporting of traditional rigid pipes; at the same time, the flexible hose structure can be used without joints over a long distance, effectively avoiding air leakage at the joints and ensuring the smooth progress of the siphon; and, by using transparent or semi-transparent visible flexible hoses, the gas accumulation situation inside the pipe can be observed in real time during use, so as to discharge the accumulated gas in time and further ensure the smooth progress of the siphon.

[0030] By setting a certain number of water inlet pipes and a certain number of water outlet pipes, the water flow rate per unit time can be unrestricted by the pipe diameter while having the characteristics of being coiled and portable for transportation.

[0031] By setting a number of water outlet pipes, different areas can be irrigated simultaneously, greatly improving the irrigation efficiency. At the same time, it avoids the damage to the crops caused by large water flow irrigating the same point, and also avoids the defect of being bulky and not easy to tow and move when multiple pipes are bundled.

[0032] The present invention can achieve zero energy consumption, is easy to start and can be automatically started and stopped repeatedly. Starting does not consume any energy, which is both energy-saving and applicable to remote areas without energy sources;

[0033] The siphon water conveyance system of the present invention has a lower cost compared with the existing drainage and irrigation stations.

[0034] When the present invention is in use, it will not cause any damage to the dam. No water diversion channels are dug or construction is carried out on the dam. The water flow does not pass through the dam and will not scour the dam. It does not affect the traffic on the dam. Because no water diversion channels are dug or construction is carried out on the dam, it does not affect the traffic on the dam. Description of the Drawings

[0046] Detailed implementation manner one: In combination with Figures 1 to 8 Describe this implementation manner. A novel siphon water conveyance system includes a siphon pagoda 1, a filter cage 2, a water inlet water distributor 3, several water inlet pipes 4 and several water outlet pipes 5. Among them,

[0047] One ends of several water inlet pipes 4 and one ends of several water outlet pipes 5 are respectively and correspondingly connected to the water inlet side and the water outlet side of the siphon pagoda 1,

[0048] The other ends of a plurality of water inlet pipes 4 are all connected to a water inlet distributor 3.

[0049] A first valve 6 is arranged on the water inlet distributor 3.

[0050] A second valve 7 is installed at the other end of each water outlet pipe 5.

[0051] The filter cage 2 is connected and arranged on the water inlet side of the water inlet distributor 3.

[0052] The siphon pagoda 1 includes a siphon main body 1-1 and an exhaust chamber 1-2 connected and arranged at the top of the siphon main body 1-1. A third valve 1-3 and a fourth valve 1-4 are respectively arranged at the top inlet and the bottom outlet of the exhaust chamber 1-2.

[0053] The siphon pagoda 1 is a visible structure, and each water inlet pipe 4 and each water outlet pipe 5 are all visible flexible hoses.

[0054] The siphon main body 1-1 has a structure that is narrower at the top and wider at the bottom, greatly increasing the stability of the siphon pagoda 1 and preventing the siphon pagoda 1 from tipping over.

[0055] The top inlet of the exhaust chamber 1-2 is the water filling port.

[0056] The valves described in the present invention are all quick-connect valves.

[0057] During use, first close the first valve 6 and the second valve 7, then open the third valve 1-3 and the fourth valve 1-4, and add water from the water filling port. During the water filling process, gradually empty the gas in the water inlet pipe 4 and the water outlet pipe 5 until the water overflows from the water filling port; at this time, close the third valve 1-3 and the fourth valve 1-4, then first open the first valve 6, and then open the second valve 7, and the siphon effect can be formed, and the water smoothly passes through the siphon water delivery system and flows out after crossing the dam.

[0058] During the use process, in order to ensure the smooth formation of the siphon effect, the following two conditions need to be met:

[0059] The vertical height h between the bottom surface of the siphon pagoda 1 and the water surface of the water source is less than the height of the water column corresponding to one atmospheric pressure, which is 10.3 meters.

[0060] The vertical height H between the water surface of the water source and the water outlet of the siphon water delivery system is greater than 0, that is, the water surface of the water source is higher than the water outlet of the siphon water delivery system.

[0061] Each water inlet pipe 4 and each water outlet pipe 5 are transparent or semi-transparent visible hoses, which makes the siphon water conveyance system have the convenience of being coiled for transportation, effectively overcoming the problem of inconvenient carrying and transportation of traditional rigid pipes. At the same time, the hose structure can be used over a long distance without joints, effectively avoiding air leakage at the joints and ensuring the smooth progress of siphon. Moreover, by using transparent or semi-transparent visible hoses, the gas accumulation situation inside the pipe can be observed in real time during use, so as to timely discharge the accumulated gas and further ensure the smooth progress of siphon.

[0062] The siphon pagoda 1 is a visible structure, and its specific material can be the same as that of the water inlet pipe 4 or the water outlet pipe 5. When flowing water, both the bubbles in the siphon pagoda 1 can be seen and the vacuum pumping or 1 atmospheric pressure negative pressure can be ensured without collapsing or cracking.

[0063] When the water flow rate requirement per unit time is not high, only one water inlet pipe 4 and one water outlet pipe 5 can be selected to be connected; or the number of connected water inlet pipes 4 and water outlet pipes 5 can be adjusted at any time according to the change of the water flow rate requirement per unit time.

[0064] By setting a certain number of water inlet pipes 4 and a certain number of water outlet pipes 5, the water flow rate per unit time can be unrestricted by the pipe diameter while having the characteristics of being coiled and portable for transportation. The pipe materials of the water inlet pipe 4 and the water outlet pipe 5 can not only withstand negative pressure but also have a certain degree of coiling property.

[0065] The siphon water conveyance system of the present invention has a lower cost compared with the existing drainage and irrigation stations.

[0066] When the present invention is in use, it will not cause any damage to the dam. No diversion channels are dug or construction is carried out on the dam. The water flow does not pass through the dam and will not scour the dam. It does not affect the dam traffic. Since no diversion channels are dug or construction is carried out on the dam, the traffic on the dam is not affected. The flow rate can be infinitely large.

[0067] Due to the coiling and portability of the water inlet pipe 4 and the water outlet pipe 5, the water inlet pipe 4 and the water outlet pipe 5 can be laid along the ground over a long distance according to the changes in the height of the terrain, avoiding the inability of rigid pipes such as steel pipes to be laid over a long distance without joints, and also avoiding the necessity of using turning joints to connect and change directions when the rigid pipes encounter changes in the ground slope. The possibility of air leakage at too many joints damaging the siphon effect is avoided.

[0068] By setting a number of water outlet pipes 5, different areas can be irrigated simultaneously, greatly improving the irrigation efficiency. At the same time, the damage to crops caused by large water flow pouring on the same point is avoided, and the defect of the multi-pipe cluster being bulky and not easy to tow and move is also avoided.

[0069] The present invention can achieve zero energy consumption, is easy to start and can be repeatedly automatically started and stopped. Starting does not consume any energy, which is both energy-saving and applicable to remote areas without energy sources.

[0070] Such as Figure 2In the first application scenario shown, during flood drainage, it can be automatically started and stopped repeatedly according to the drainage situation.

[0071] Such as Figure 3 The second application scenario shown: Use a new siphon water delivery system to transport the water in the pond across the field to the reservoir 11 dug in the field, and then pump the water up from the reservoir 11 for irrigation, saving the trouble of transporting water from the pond to the field. It starts and stops automatically repeatedly according to the amount of water pumped, and transports the water in the pond to the reservoir 11 dug in the field.

[0072] Such as Figure 4 In the third application scenario shown, it starts and stops automatically repeatedly according to the accumulated water volume. The water outlet is immersed in a full water container placed at an appropriate height on the slope of the ditch. When the water level of the accumulated water is higher than the water level of the upper edge of the container, the new siphon water delivery system automatically starts draining, and the water in the container can automatically overflow to keep the water level unchanged. When the water level of the accumulated water is flush with the water level of the upper edge of the container, the new siphon water delivery system automatically pauses draining and keeps the new siphon water delivery system airtight, so that when the accumulated water increases and the water level of the accumulated water is higher than the water level of the upper edge of the container, the new siphon water delivery system can automatically start draining again.

[0073] When gas accumulates in the siphon main body 1-1, it will affect the water flow rate per unit time of the siphon effect and even stop the siphon effect. At this time, the third valve 1-3 can be closed and the fourth valve 1-4 can be opened to make the accumulated gas rise into the exhaust chamber 1-2, and at the same time, the water in the exhaust chamber 1-2 flows into the siphon main body 1-1, so as to complete the gas-liquid exchange and achieve the purpose of discharging the gas from the siphon main body 1-1 and the water inlet pipe 4 and the water outlet pipe 5. Then close the fourth valve 1-4, and the siphon efficiency is restored. Then open the third valve 1-3, add water from the water filling port, empty the gas in the exhaust chamber 1-2 until the water overflows from the water filling port. Close the third valve 1-3 to prepare for the next exhaust.

[0074] The water inlet pipe 4 and the water outlet pipe 5 can be semi-transparent PE polyethylene pipes or HDPE high-density polyethylene pipes or transparent steel wire hoses. They have good flexibility, so that the pipes can be coiled and supplied in a relatively long length, avoiding a large number of joints and pipe fittings and reducing the possibility of air leakage.

[0075] Scope of application of the siphon water conveyance system of the present invention: It is applicable to irrigation where the water surface is higher than the irrigated fields, and also applicable to irrigation where the water source surface is lower than the irrigated fields. It can also be used for non-destructive flood discharge and drainage during flood disasters. It can also be used as a toy project integrating fun entertainment, knowledge and technology in families, scenic spots, children's playgrounds, parks, and science and technology parks. Specifically, for example: 1. Irrigate the Yellow River water from the above-ground river in the Yellow River Basin. When reclaiming fields from lakes, irrigate the reclaimed fields by diverting lake water, and irrigate mountain farmland. 2. For drought-resistant watering, water from a high water source can be diverted across a dam to a place lower than the water source surface for drought-resistant watering. Or the new siphon water conveyance system of the present invention can be used to transport the water in the pond across the high fields to the storage pool 11 dug in the fields, and then pump the water up from the storage pool 11 for irrigation, saving the trouble of transporting water from the pond to the fields. 3. During the flood season, in order to prevent the key protected dike sections from bursting or overtopping, the new siphon water conveyance system of the present invention is used for flood discharge in the non-key protected dike sections, and the new siphon water conveyance system of the present invention is stored as a common flood control tool in the flood discharge dike sections prone to flood. 4. For farmland drainage, the new siphon water conveyance system of the present invention is generally used and stored as a common tool. 5. In scenic spots, children's playgrounds, parks, and science and technology parks, the new siphon water conveyance system of the present invention is used as a project integrating entertainment, technology, and knowledge. 6. The new siphon water conveyance system of the present invention can be used to produce family children's, students' toys and teaching aids integrating entertainment and knowledge.

[0076] The other ends of a plurality of water outlet pipes 5 are all connected to a water outlet water distributor 8, and a fifth valve 9 is arranged on the water outlet water distributor 8. With such a design, by setting the water outlet water distributor 8, the water flow in the water outlet pipes 5 is concentrated and discharged, which is convenient for centrally diverting water into the pit pool 12 for water storage or other containers. Through the fifth valve 9, it is convenient to achieve centralized control of the water outlet. When it is necessary to centrally discharge the water flow, the fifth valve 9 and the second valves 7 on each water outlet pipe 5 are all normally open. When it is necessary to control the water flow rate per unit time, the second valves 7 on some of the water outlet pipes 5 can be selected to be normally open, and the second valves 7 on the remaining water outlet pipes 5 are closed, so as to reduce the water flow, and thus flexibly control the water flow rate per unit time.

[0077] The outlet end of the water outlet water distributor 8 is connected with a water outlet elbow 10, and the water outlet of the water outlet elbow 10 is arranged upward. With such a design, by setting the water outlet elbow 10 with an upward water outlet, air is prevented from entering from the water outlet, thereby ensuring the smooth progress of the siphon. The water outlet can be vertically upward or obliquely upward, and the bending angle of the water outlet elbow 10 is between 0 - 180°.

[0078] A number of first water inlet connecting pipes 1-5 are connected to the water inlet side of the siphon pagoda 1 in a communicating manner, and a number of first water outlet connecting pipes 1-6 are connected to the water outlet side of the siphon pagoda 1 in a communicating manner. A number of second water outlet connecting pipes 3-1 are connected to the water outlet side of the water inlet water distributor 3 in a communicating manner. One ends of a number of water inlet pipes 4 are hermetically connected to the corresponding first water inlet connecting pipes 1-5, the other ends of the number of water inlet pipes 4 are hermetically connected to the corresponding second water outlet connecting pipes 3-1, and one ends of a number of water outlet pipes 5 are hermetically connected to the corresponding first water outlet connecting pipes 1-6. With such a design, it is convenient for the connection between the water inlet pipe 4 and the water inlet water distributor 3, between the water inlet pipe 4 and the siphon pagoda 1, and between the water outlet pipe 5 and the siphon pagoda 1.

[0079] The lengths of every two adjacent first water inlet connecting pipes 1-5 are different, the lengths of every two adjacent first water outlet connecting pipes 1-6 are different, and the lengths of every two adjacent second water outlet connecting pipes 3-1 are different. With such a design, the connection interfaces of every two adjacent pipes are arranged in a staggered manner, effectively avoiding interference between the water inlet pipe 4 or the water outlet pipe 5 and the adjacent pipes during installation, and thus making it more convenient for the installation of the water inlet pipe 4 and the water outlet pipe 5. Preferably, as Figure 1 shown, the lengths of the number of first water outlet connecting pipes 1-6 gradually decrease from the middle to both sides, and the length distributions of the number of first water inlet connecting pipes 1-5 and the number of second water outlet connecting pipes 3-1 are the same as those of the number of first water outlet connecting pipes 1-6.

[0080] A number of second water inlet connecting pipes 8-1 are connected to the water inlet side of the water outlet water distributor 8 in a communicating manner, and the other ends of the number of water outlet pipes 5 are hermetically connected to the corresponding second water inlet connecting pipes 8-1.

[0081] The lengths of every two adjacent second water inlet connecting pipes 8-1 are different. With such a design, the connection interfaces of every two adjacent pipes are arranged in a staggered manner, effectively avoiding interference between the water outlet pipe 5 and the adjacent pipes during installation, and thus making it more convenient for the installation between the water outlet pipe 5 and the water outlet water distributor 8.

[0082] The filter cage 2 includes a support frame and a filter screen sleeved outside the support frame. The water inlet of the water inlet water distributor 3 extends into the middle of the filter cage 2. With such a design, the water inlet is inserted from the mouth of the filter cage 2 to the middle of the filter cage 2, preventing leaves and weeds in the water from blocking the water inlet pipe 4, and at the same time enabling the water inlet to be at a certain height from the mud at the bottom of the water, preventing the mud from being sucked into the water inlet pipe 4. Compared with the ordinary flat filter head tightly covering the water inlet, the advantage of the filter cage 2 of the present invention is that the filtering area is large, the distance between the water inlet in the middle of the filter cage 2 and the mesh holes is far, and even if some mesh holes are blocked, the entire water inlet can still be filled with water at full caliber, without affecting the water inlet efficiency of the water inlet. The support frame is preferably of a foldable structure, which can be erected during use and folded and stored when not in use.

[0083] The third valve 1-3 is a quick-connect ball valve. With such a design, it is prevented that when the exhaust chamber 1-2 exhausts, the siphon tower 1 is directly communicated with the atmosphere, resulting in water flowing out from the water inlet and outlet of the new siphon water delivery system and causing the siphon to terminate.

[0084] A number of first water inlet connecting pipes 1-5, a number of first water outlet connecting pipes 1-6 and a number of second water outlet connecting pipes 3-1 are all distributed in a single row, rectangular array or circular array. With such a design, the distribution mode of the water inlet pipe 4 is more diverse and the water outlet adjustment range is wider. The arrangement mode of a number of second water inlet connecting pipes 8-1 is the same as that of a number of first water outlet connecting pipes 1-6. The number of the first water inlet connecting pipe 1-5, the first water outlet connecting pipe 1-6, the second water outlet connecting pipe 3-1 and the second water inlet connecting pipe 8-1 can all be one, that is, single-pipe arrangement.

[0085] A using method of the above new siphon water delivery system, by adjusting the positions of the water inlet and outlet of the siphon water delivery system, the siphon water delivery system is made applicable to different water diversion requirements. Among them, when it is used to divert high-level water sources across the dam to low-level water sources (such as during flood discharge), the water inlet of the new siphon water delivery system is set higher than the water outlet of the new siphon water delivery system; when it is used to divert low-level water sources across the bank to the dam fields, a storage pool 11 is dug in advance in the dam fields, then the water inlet of the new siphon water delivery system is set below the water surface of the low-level water source, and the water outlet of the new siphon water delivery system is set in the storage pool 11 and the water outlet is set lower than the water inlet (the low-level water source can be a pond, a lake, a river, etc. It is more convenient to take water from the storage pool 11 near the dam fields, that is, the siphon water delivery system is used to transport the water in the low-level water source across the fields to the pre-dug storage pool 11, and then the water is lifted from the storage pool 11 for irrigation, saving the heavy labor of transporting water from the low-level water source to the fields. According to the amount of water lifted, the new siphon water delivery system can automatically start and stop repeatedly to transport the water in the low-level water source into the storage pool 11 in the fields); when it is used to drain the low-lying water in the fields, first a pit pool 12 is dug at the deepest part of the low-lying water in the fields, then a water bucket 13 is placed on the slope of the river ditch on the other side of the dam, the water inlet of the new siphon water delivery system is set below the water level in the pit pool 12, and the water outlet of the new siphon water delivery system is set in the water bucket 13. When the water levels in the pit pool 12 and the water bucket 13 are level, the siphon pauses. When the water accumulation in the pit pool 12 increases, the siphon starts automatically.
