Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment technology, and more specifically, to a siphon-type vegetable planting water replenishment system that adapts to soil moisture conditions. Background Technology

[0002] In modern agriculture, vegetables are an important agricultural product, and the precise supply of water during their growth process plays a decisive role in their yield and quality. Soil moisture, or soil water content, directly affects the absorption of water and nutrients by vegetable roots. Different growth stages and different varieties of vegetables have significantly different soil moisture requirements, making it crucial to ensure high-quality and high-yield vegetables by supplementing water as needed.

[0003] Traditional methods of watering vegetable cultivation, such as flood irrigation and sprinkler irrigation, suffer from serious water waste, soil compaction, and vegetable pests and diseases because they cannot detect changes in soil moisture in real time. While existing smart drip irrigation systems can achieve a certain degree of precision irrigation, they rely heavily on complex sensor networks and external power sources. This results in high equipment costs, difficult maintenance, and inability to operate stably in remote areas or environments with unstable power supplies, thus affecting the watering effect.

[0004] Meanwhile, the siphon principle has been applied in water conservancy projects and small irrigation devices. However, traditional siphon irrigation devices lack the ability to adaptively adjust soil moisture and cannot dynamically adjust the amount and timing of water replenishment according to the needs of vegetable growth and the actual soil moisture content. With the increasing attention paid to green agriculture and water-saving agriculture, and the development of vegetable planting towards large-scale and intelligent methods, the development of a siphon vegetable planting water replenishment system that can sense soil moisture in real time and automatically adjust the amount of water replenishment has become an urgent need to solve the current water replenishment problem in vegetable planting and promote the innovation of agricultural irrigation technology. Utility Model Content

[0005] The purpose of this invention is to provide a siphon-type water supply system for vegetable cultivation that adapts to soil moisture conditions, in order to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adaptive soil moisture siphon-type vegetable planting irrigation system includes a storage cylinder. A main pipe is fixedly installed on the bottom of the storage cylinder. A siphon valve is fixedly installed on the end of the main pipe that extends into the storage cylinder. A second flow control valve is fixedly installed on the pipe outside the storage cylinder. Multiple auxiliary pipes are fixedly installed on the main pipe, and multiple drip irrigation heads are fixedly installed on the auxiliary pipes. A humidity sensor for detecting soil moisture is installed on one side of the main pipe. A control host is installed on one side of the storage cylinder. A water inlet pipe is fixedly installed on the top of the storage cylinder, and a first flow control valve is fixedly installed on the water inlet pipe.

[0008] Preferably, a plurality of support legs are fixedly installed at the bottom of the storage cylinder, and a support base is fixedly installed at the bottom end of the support legs.

[0009] Preferably, the top of the storage cylinder is provided with an exposure hole that communicates with the outside world, and the exposure hole is located for manual operation.

[0010] Preferably, a dust cover is hinged to the top surface of the storage cylinder. When the dust cover is closed, it covers the top surface of the storage cylinder and seals the exposed holes.

[0011] Preferably, a handle is fixedly installed on the back of the dust cover, and the handle has an arc-shaped cross-section.

[0012] Preferably, the outlet end of the water inlet pipe inserted into the storage cylinder can also be detachably fitted with a filter bag, which is used for water filtration.

[0013] Preferably, a threaded pipe is fixedly installed at the outlet end of the inlet pipe, and a threaded connector is fixedly installed at the top end of the filter bag. The threaded connector is fitted onto the threaded pipe and threadedly connected to the threaded pipe.

[0014] This feature facilitates the loading and unloading of filter bags.

[0015] Preferably, a limiting ring is fixedly installed on the top end of the threaded tube, and a sealing ring is embedded in the top surface of the threaded joint, with the sealing ring abutting against the bottom surface of the limiting ring;

[0016] This setting improves the sealing effect and prevents leakage.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a humidity sensor to detect soil moisture in real time and transmits the data to the control host. The control host controls the opening and closing of the flow control valve according to the preset threshold, and then uses the siphon principle of the siphon valve to deliver water. This achieves the effect of automatically adjusting the amount and timing of water replenishment according to the soil moisture, thereby achieving precise irrigation, avoiding water waste, and reducing the probability of vegetable diseases and pests.

[0019] 2. This utility model uses the siphon principle for water replenishment, eliminating the need for a complex external power source to drive the water pump. The irrigation structure consisting of the main pipe, secondary pipe, and drip irrigation head is simple and practical, reducing equipment costs and maintenance difficulty, and achieving stable operation even in remote areas or environments with unstable power.

[0020] 3. This utility model achieves effective filtration of water entering the storage tank by setting a detachable filter bag at the water outlet end of the inlet pipe, combined with a threaded connection structure, preventing the drip irrigation head from clogging, and thus ensuring the long-term stable operation of the water replenishment system and improving irrigation efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 This utility model provides a technical solution: an adaptive soil moisture siphon-type vegetable planting water replenishment system, including a storage cylinder 1. A main pipe 3 is fixedly installed on the bottom cylinder of the storage cylinder 1. A siphon valve 31 is fixedly installed on the end of the main pipe 3 that extends into the storage cylinder 1. A second flow control valve 30 is fixedly installed on the pipe of the main pipe 3 located outside the storage cylinder 1. Multiple auxiliary pipes 32 are fixedly installed on the main pipe 3. Multiple drip irrigation heads 33 are fixedly installed on the auxiliary pipes 32. A humidity sensor for detecting soil moisture is provided on one side of the main pipe 3. The device 14 has a control host 15 on one side of the storage cylinder 1. A water inlet pipe 2 is fixedly installed on the top of the storage cylinder 1. A first flow control valve 20 is fixedly installed on the water inlet pipe 2. The soil moisture is detected in real time by the humidity sensor 14 and the data is transmitted to the control host 15. The control host 15 controls the opening and closing of the second flow control valve 30 according to the preset threshold, so that the system can automatically adjust the amount and timing of water replenishment according to the actual soil moisture, avoid over- or under-irrigation, and achieve the effects of precise irrigation, water conservation, and promotion of healthy vegetable growth.

[0031] like Figure 1 As shown, multiple support legs 10 are fixedly installed at the bottom of the storage cylinder 1, and a support base 11 is fixedly installed at the bottom end of the support legs 10, so that the storage cylinder 1 stands firmly on the ground, ensuring that the entire water replenishment system remains stable during operation and avoiding the impact of shaking on the normal operation of the system and the life of the components.

[0032] like Figure 1 As shown, the top of the storage cylinder 1 is provided with an exposure hole 12 that connects to the outside, which facilitates manual operation by staff, such as checking internal components and cleaning debris, making system maintenance more convenient and efficient.

[0033] like Figure 1 As shown, a dust cover 13 is hinged to the top surface of the storage cylinder 1. When the dust cover 13 is closed, it covers the top surface of the storage cylinder 1 and seals the exposed hole 12. When no manual operation is performed, the exposed hole 12 is sealed to prevent dust, debris and other objects from entering the storage cylinder 1, reduce the risk of internal component contamination and ensure the normal operation of the system.

[0034] like Figure 1As shown, a handle 131 is fixedly installed on the back of the dust cover 13. The cross-section of the handle 131 is arc-shaped, which conforms to the ergonomic design and makes it convenient for staff to open and close the dust cover 13, thereby improving the convenience and comfort of operation.

[0035] like Figure 1 and Figure 2 As shown, the outlet end of the water inlet pipe 2, which is inserted into the storage cylinder 1, can also be detachably installed with a filter bag 23. The filter bag 23 is used for water filtration. It can effectively filter the water entering the storage cylinder 1, intercept impurities in the water, and prevent impurities from entering the main pipe 3, the secondary pipe 32 and the drip head 33 and causing blockage, thus ensuring a stable water supply to the system.

[0036] like Figure 1 and Figure 2 As shown, a threaded pipe 21 is fixedly installed at the outlet end of the water inlet pipe 2, and a threaded connector 24 is fixedly installed at the top of the filter bag 23. The threaded connector 24 is fitted onto the threaded pipe 21 and threadedly connected to the threaded pipe 21, which facilitates quick disassembly and installation of the filter bag 23. When the filter bag 23 needs to be cleaned or replaced, the operation is simple and convenient, saving maintenance time and labor costs.

[0037] like Figure 2 and Figure 3 As shown, a limiting ring 22 is fixedly installed on the top end of the threaded pipe 21, and a sealing ring 241 is embedded in the top surface of the threaded joint 24. The sealing ring 241 abuts against the bottom surface of the limiting ring 22, which enhances the sealing performance at the connection between the water inlet pipe 2 and the filter bag 23, effectively preventing water leakage at the connection and ensuring the normal water storage and supply of the storage cylinder 1.

[0038] It is worth noting that the inner diameter of the threaded connector 24 is between 3cm and 6cm. When impurities accumulate inside the filter bag 23, the filter bag 23 can be passed through the threaded connector 24 from the inside and turned over before cleaning.

[0039] It is worth noting that the humidity sensor 14 can be a high-precision capacitive sensor, which can monitor soil moisture content in real time. The control host 15 has a corresponding control circuit board with a built-in control algorithm. This algorithm can automatically adjust the first flow control valve 20 and the second flow control valve 30 according to the water requirements of different vegetable varieties and growth stages, achieving precise water replenishment. Specifically, the humidity sensor 14 first detects the soil moisture and transmits the moisture value data to the control host 15. By comparing this value with the value set in the control host 15, it is determined whether the current soil environment needs water replenishment. When no water replenishment is needed, the first flow control valve 20 and the second flow control valve 30 do not operate. When water replenishment is needed, the control host 15 controls the first flow control valve 20 to open to the corresponding size. At this time, external water can enter the storage tank 1 through the water inlet pipe 2. At the same time, the control host 15 also controls the opening and closing size of the second flow control valve 30. When the amount of water stored in the storage tank 1 reaches the amount that the siphon valve 31 can open, the siphon valve 31 automatically opens, and the water in the storage tank 1 can flow out through the main pipe 3, the secondary pipe 32 and the drip irrigation head 33, realizing the adaptive siphon water replenishment operation based on soil moisture.

[0040] The working principle of the siphon valve 31 is as follows: when the water level in the storage tank 1 rises, the float ball of the siphon valve 31 rises accordingly, and drives the valve core to move upward through the linkage mechanism, so that the siphon valve 31 opens. The water in the storage tank 1 flows out through the main pipe 3 under the siphon effect. As the water level drops, the float ball falls, and under the action of the reset spring, the valve core moves downward to close the siphon valve and stop water replenishment. The whole process does not require external energy drive. It automatically controls the water flow by utilizing water level changes and the siphon principle, so as to realize the automation and energy saving of water replenishment.

[0041] Finally, it should be noted that the control host 15, humidity sensor 14, first flow control valve 20 and second flow control valve 30 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0042] When using the adaptive soil moisture siphon vegetable planting water replenishment system of this utility model, firstly, the storage cylinder 1 is securely installed at a position higher than the vegetable planting area by the support leg 10 and the support base 11, and water is injected into the storage cylinder 1 through the water inlet pipe 2. When injecting water, the first flow control valve 20 is in the open state, and the water flows into the storage cylinder 1 after being filtered through the filter bag 23.

[0043] During system operation, the humidity sensor 14 detects soil moisture in real time and transmits the data to the control host 15. The control host 15 compares the received humidity value with an internal preset threshold. If the soil moisture is lower than the lower threshold, the control host 15 controls the first flow control valve 20 to open, replenishing the water in the storage tank 1. At the same time, it controls the second flow control valve 30 to adjust to a suitable opening. When the water in the storage tank 1 reaches the activation condition of the siphon valve 31, the siphon valve 31 automatically opens, and the water in the storage tank 1 flows sequentially through the main pipe 3 and the secondary pipe 32, dripping from the drip irrigation head 33 to the soil around the vegetable roots. As irrigation progresses, when the soil moisture reaches the upper threshold, the control host 15 controls the second flow control valve 30 to close, and the siphon valve 31 also stops working, pausing water replenishment.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
