Description

Technical Field

[0001] This utility model relates to the field of irrigation devices, and in particular to a water-saving irrigation device for drought relief in water conservancy. Background Technology

[0002] In modern agriculture, water conservancy and drought-resistant irrigation devices are core equipment, covering types such as drip irrigation, sprinkler irrigation, and seepage irrigation. They deliver water directly to the crop roots, significantly reducing evaporation and seepage losses, effectively alleviating water shortages, and ensuring agricultural production in arid regions.

[0003] Existing water-saving irrigation devices for drought relief are irrigation equipment that maintains crop growth by efficiently utilizing water resources under arid and water-scarce conditions. The core function is to reduce water consumption through technical means, while improving irrigation uniformity and water resource utilization. Most irrigation devices use drip irrigation, which delivers water directly to the crop roots, reducing evaporation and seepage losses. However, during peak crop water demand periods or when soil moisture is insufficient, drip irrigation systems, due to the small flow rate of a single dripper, cannot quickly meet the water needs of large-area crops, easily leading to insufficient water supply. In arid regions, the high-temperature season is a critical growth period for crops, and crop yield reduction can occur due to water stress. Utility Model Content

[0004] The purpose of this utility model is to provide a water-saving irrigation device for drought relief in order to solve the problems mentioned in the background art.

An installation rod is fixedly connected to the vertical connecting pipe in the middle position. Multiple sets of high-pressure nozzles are installed on the installation rod. A flow control mechanism is installed at the bottom of the vertical connecting pipe in the middle position. The flow control mechanism is used to control the direction of water flow.

[0011] The technical effects and advantages of this utility model are as follows: This water-saving irrigation device for drought relief adopts a combined drip and sprinkler irrigation mode. Multiple sets of vertical and horizontal connecting pipes form a drip irrigation network. Through drip irrigation, precise water supply to the crop root zone can be maintained, avoiding deep seepage and surface evaporation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] This utility model provides, for example Figure 1 - Figure 3 The water-saving irrigation device for drought relief shown includes a support foot 3 fixedly installed on the ground. The support foot 3 serves as the fixed base of the device, which securely installs the vertical connecting pipe 1 on the ground to prevent the pipe from tilting or shifting due to water flow impact or external force during irrigation. The support foot 3 is made of concrete and is embedded 30cm into the ground to ensure that the vertical connecting pipe 1 remains vertically stable when the high-pressure nozzle 6 is working.

[0016] Multiple sets of vertical connecting pipes 1 are installed on the supporting foot 3. Multiple sets of horizontal connecting pipes 2 are fixedly connected to the multiple sets of vertical connecting pipes 1. The vertical connecting pipes 1 and the horizontal connecting pipes 2 form the main framework of the drip irrigation network. Water is continuously delivered to the crop root layer through drip irrigation holes 4 to maintain precise irrigation. The vertical connecting pipes 1 and the horizontal connecting pipes 2 are manufactured as a single piece to reduce the risk of water leakage at the connection. The horizontal connecting pipes 2 are connected to the vertical connecting pipes 1. Both the horizontal connecting pipes 2 and the vertical connecting pipes 1 are provided with drip irrigation holes 4. The drip irrigation holes 4 are evenly distributed on the surface of the vertical connecting pipes 1 and the horizontal connecting pipes 2, allowing water to slowly seep in at a low flow rate of 2-4 L / h, avoiding surface runoff and deep seepage, ensuring uniform soil moisture around the roots of each crop, reducing fruit cracking caused by local drought, and improving water use efficiency. An installation rod 5 is fixedly connected to the vertical connecting pipe 1 in the middle position. Multiple sets of high-pressure nozzles 6 are installed on the installation rod 5. The high-pressure nozzles 6 can spray quickly at a high flow rate of 200-300L / h during peak water demand periods to replenish the moisture of the surface soil. A flow control mechanism 7 is installed at the bottom of the vertical connecting pipe 1 in the middle position. The flow control mechanism 7 is used to control the water flow to switch between drip irrigation and sprinkler irrigation modes.

[0017] The flow control mechanism 7 includes: The first guide pipe 701 is fixedly connected to the bottom of the mounting rod 5 at its upper end. The first guide pipe 701 is connected to the mounting rod 5 and guides the water flow to the high-pressure nozzle 6. The second guide pipe 702 is fixedly connected at its upper end to the bottom of the vertical connecting pipe 1. The second guide pipe 702 is connected to the vertical connecting pipe 1 and supplies water to the drip irrigation network through the guide hole 10. The three-way valve body 703 is installed at one end of the first guide pipe 701 and the second guide pipe 702. The three-way valve body 703 can switch the water flow path. As the core component of the flow control mechanism 7, the three-way valve body 703 achieves dynamic switching of the water flow path through the rotation or sliding of the internal valve core: when the valve core turns to the direction of the first guide pipe 701, the water flow is guided to the high-pressure nozzle 6 on the mounting rod 5, and the sprinkler mode is turned on to quickly replenish the surface soil moisture; when the valve core turns to the direction of the second guide pipe 702, the water flow is evenly distributed through the guide hole 10 to the drip irrigation network composed of the vertical connecting pipe 1 and the horizontal connecting pipe 2 to achieve precise water supply to the root layer; when the valve core is in the middle position, it can connect the two paths at the same time to form the coordinated operation of drip irrigation and sprinkler irrigation. This design allows the device to flexibly adjust the irrigation method according to the crop's water requirement stage, ensuring water-saving efficiency and improving emergency water replenishment capacity. It enables drip irrigation and sprinkler irrigation to operate independently or in combination. During drought warnings, the second guide pipe 702 is closed by the three-way valve body 703, and the first guide pipe 701 is opened, so that all water flows through the high-pressure nozzle 6 for emergency water replenishment.

[0018] A fixed pipe 8 is installed at the end of the three-way valve body 703 away from the first guide pipe 701 and the second guide pipe 702. A connecting flange 9 is fixedly connected to the fixed pipe 8. The connecting flange 9 facilitates quick disassembly and assembly of the pipe and adapts to different irrigation scenarios. The fixed pipe 8 is connected to the water pump outlet through the connecting flange 9 to realize the rapid deployment of the device.

[0019] The second guide pipe 702 is provided with a guide hole 10 at a position inside the vertical connecting pipe 1. The guide hole 10 is used to connect multiple sets of vertical connecting pipes 1 and multiple sets of horizontal connecting pipes 2.

[0020] Multiple sets of vertical connecting pipes 1 and multiple sets of horizontal connecting pipes 2 are manufactured as a single piece, effectively reducing the risk of water leakage at the connection points.

[0021] Both the vertical connecting pipe 1 and the horizontal connecting pipe 2 are made of polyvinyl chloride (PVC). PVC pipes are highly corrosion-resistant and can transport aqueous solutions containing fertilizers for extended periods.

[0022] Example 1: This water-saving irrigation device for drought relief effectively solves the water supply contradiction during the peak water demand period of crops in arid regions through the coordinated design of drip irrigation and sprinkler irrigation. The drip irrigation network composed of vertical connecting pipe 1 and horizontal connecting pipe 2 can maintain precise water supply to the crop root layer for a long time and avoid water waste. The high-pressure sprinkler 6 can quickly switch irrigation modes through the flow control mechanism 7, and quickly replenish the surface soil moisture with a large flow rate for a short time when the soil moisture is insufficient, shortening the time of crop water shortage. This combination mode not only ensures water-saving efficiency, but also enhances emergency moisture replenishment capacity. It is especially suitable for the critical growth period of cash crops in arid regions and effectively reduces the risk of yield reduction caused by drought.

[0023] Example 2: When it is necessary to switch irrigation modes, the irrigation mode can be quickly switched by controlling the valve core of the three-way valve body 703: When it is necessary to start the sprinkler mode, turn the valve core to the direction of the first guide pipe 701. At this time, all the water flow is directed to the high-pressure nozzle 6 on the mounting rod 5 to achieve rapid humidification with a large flow rate; When it is necessary to switch to the drip irrigation mode, turn the valve core to the direction of the second guide pipe 702. The water flow is evenly distributed to the drip irrigation network of the vertical connecting pipe 1 and the horizontal connecting pipe 2 through the guide hole 10 to maintain precise water supply to the root layer; If it is necessary to run the two modes at the same time, the valve core can be placed in the middle position so that part of the water flow enters the nozzle for surface humidification, and the other part continuously permeates through the drip irrigation hole 4 to meet the complex needs of different growth stages of crops. The entire switching process does not require disassembling the pipes and only requires a few seconds of operation to complete the mode adjustment.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
