Description

Technical Field

[0001] This utility model relates to a water-saving irrigation device. Background Technology

[0002] Water-saving irrigation is an irrigation method aimed at improving the efficiency of water resource utilization and achieving optimal crop growth and yield with minimal water consumption. It integrates various measures such as engineering, agriculture, and management to meet the water requirements of crops while minimizing water waste and achieving sustainable water resource utilization.

[0003] However, some irrigation systems have relatively simple water storage facilities, generally using open irrigation canals to supply water, resulting in a large evaporation rate. When the water level in the irrigation canals drops, they cannot effectively store water. In addition, some areas still use traditional irrigation methods such as flood irrigation, which leads to serious waste of water resources and low irrigation efficiency. During the irrigation process, the water source is exposed to the air for a long time, resulting in significant evaporation losses.

[0004] Chinese invention patent publication number CN120548959A discloses a water-saving irrigation device for agricultural technology promotion, including a water storage tank, a water supply hole on one side of the water storage tank, a water supply pipe connected inside the water supply hole, a diversion box connected to one side of the water supply pipe, a water pump connected inside the water storage tank, one end of the water pump connected to the water supply pipe; several mounting holes, all located on one side of the diversion box; and an irrigation component, located on one side of the diversion box, used for irrigating farmland. This patent aims to solve problems such as uneven irrigation, lack of intelligent control, and ineffective rainwater recovery, but does not involve improving the effectiveness of stored water sources. Utility Model Content

[0005] The technical problem this invention aims to solve is that water sources exposed to air for extended periods experience significant evaporation losses. To address this, a water-saving irrigation device is provided.

[0006] The technical solution of this utility model is: a water-saving irrigation device, comprising: an irrigation canal; a water storage well; a connecting pipe connecting the irrigation canal and the water storage well; a water supply component installed in the water storage well for supplying water to the outside; and a backflow prevention component comprising: a support rod, one end of which is fixedly connected to the outside of the end of the connecting pipe located in the water storage well, and the other end of which is provided with two support arms forming a T-shape with the support rod; two rotating frames, one end of which is provided with mounting holes that cooperate with the two support arms; a torsion spring, which is sleeved on the two support arms and connected between the corresponding rotating frame and the support rod; and a valve plate, one side of which is fixedly connected to the other end of the two rotating frames and adapted to the end face of the connecting pipe.

[0007] In the above scheme, the connecting pipe is provided with an upwardly curved elbow at one end of the water storage well, and the support rod is fixed to the elbow.

[0008] The water supply components described in the above scheme include: a submersible pump located at the bottom of a water storage well; a water delivery pipe, one end of which is connected to the submersible pump and the other end of which extends outside the water storage well; a connecting pipe, one end of which is connected to the water delivery pipe; a drip irrigation tape, one end of which is connected to the other end of the connecting pipe; and water outlet nozzles, which are spaced apart along the extension direction of the drip irrigation tape.

[0009] An improvement to the above solution is that a filter cover is provided at one end of the connecting pipe located in the irrigation canal.

[0010] A further improvement to the above scheme is that the top of the water storage well is provided with a well cover, the end face of the well cover is a downward-concave arc-shaped groove, the surface of the arc-shaped groove is provided with several guide grooves, and the center of the well cover is provided with a through hole for the water supply pipe to pass through.

[0011] A further improvement to the above solution is that the well cover is covered with a protective cover, the protective cover has several guide holes, and the center of the protective cover has a through hole for the water pipe to pass through.

[0012] The end face of the protective cover described in the above scheme is an upward-convex arc shape.

[0013] Another improvement to the above scheme is that a sealing ring is provided on the side of the valve plate that contacts the connecting pipe.

[0014] The beneficial effects of this utility model are that by using irrigation canals, water storage wells, and connecting pipes in combination, irrigation water or rainwater can be stored. Simultaneously, with the cooperation of water supply components, the stored water can be precisely irrigated to the fields, effectively reducing irrigation water evaporation and ensuring accurate water delivery. The check valve component, with its support rod and rotating frame, allows the check valve plate to rotate. Under the counterweight rotation of the check valve plate, when the water level in the irrigation canal cavity is lower than that in the water storage well cavity, the connecting pipe can be sealed, preventing water from the water storage well cavity from flowing back into the irrigation canal cavity. The protective cover covers the top of the well cover, reducing water evaporation in the water storage well cavity. Simultaneously, the protective cover's interception function prevents foreign objects from entering the water storage well cavity. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments implemented by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] A water-saving irrigation device includes: an irrigation canal 1; a water storage well 2; a connecting pipe 3 connecting the irrigation canal and the water storage well; a water supply component 7 installed in the water storage well for supplying water to the outside; and a backflow prevention component 8, comprising: a support rod 81, one end of which is fixed to the outside of the connecting pipe at one end of the water storage well, and the other end of which has two support arms forming a T-shape with the support rod; two rotating frames 83, one end of which has mounting holes that mate with the two support arms; a torsion spring 84, which is sleeved on the two support arms and connected between the corresponding rotating frames and the support rod; and a valve plate 82, one side of which is fixed to the other end of the two rotating frames and adapted to the end face of the connecting pipe.

[0019] In one embodiment of this utility model, the water supply assembly may include: a submersible pump 72, which is located at the bottom of a water storage well; a water delivery pipe 71, one end of which is connected to the submersible pump and the other end extends outside the water storage well; a connecting pipe 73, one end of which is connected to the water delivery pipe; a drip irrigation tape 74, one end of which is connected to the other end of the connecting pipe, and there may be multiple drip irrigation tapes; and water outlet nozzles 75, which are spaced apart along the extension direction of the drip irrigation tape. Alternatively, the connecting pipe may be omitted, and the water delivery pipe may be directly connected to the drip irrigation tape.

[0020] In one embodiment of this utility model, the connecting pipe has an upwardly curved elbow at one end located in the water storage well, and the support rod is fixed to the elbow. The elbow creates an inclined angle to facilitate valve plate repositioning. Alternatively, the elbow can be omitted, and the connecting pipe can be a straight structure.

[0021] As an embodiment of this utility model, the connecting pipe is provided with a filter cover 9 at one end of the irrigation canal, which can filter large particulate impurities.

[0022] In one embodiment of this utility model, the top of the water storage well is provided with a well cover 4, the end face of the well cover is a downwardly recessed arc-shaped groove 5, and the surface of the arc-shaped groove is provided with a plurality of guide channels 6, which are distributed in a ring. The center of the well cover is provided with a through hole for a water supply pipe to pass through. Rainwater can be introduced into the water storage well through the arc-shaped groove and the guide channels.

[0023] In one embodiment of this utility model, a protective cover 10 is fitted over the well cover. The end face of the protective cover is an upwardly convex arc shape; a flat protective cover is also acceptable. The protective cover has several guide holes, and a through hole for a water pipe to pass through is located in the center of the protective cover. By providing the protective cover 10, the top of the well cover 4 is covered, thereby reducing the evaporation of water from the inner cavity of the water storage well 2. Simultaneously, the protective cover 10 intercepts and prevents foreign objects from entering the inner cavity of the water storage well 2.

[0024] In one embodiment of this utility model, a sealing ring 85 is provided on the side of the valve plate that contacts the connecting pipe. The sealing ring ensures that the valve plate prevents leakage when it contacts the connecting pipe.

[0025] The above embodiments can be combined arbitrarily as needed, and as long as the resulting technical solutions do not conflict, they all fall within the protection scope of this utility model.

[0026] The working principle of this utility model is as follows: When using this utility model, the user pours water into the inner cavity of the connecting pipe 3 through the irrigation canal 1 and into the inner cavity of the water storage well 2. Simultaneously, under the pressure of the water source, the valve plate 82 rotates around the rotating frame 83 and the torsion spring 84 as the rotation center, causing the valve plate 82 to release the blockage on the left end of the connecting pipe 3 and replenish water to the inner cavity of the water storage well 2. After the water level in the inner cavity of the irrigation canal 1 decreases, under the action of gravity, the torsion force of the torsion spring 84, and the water pressure in the inner cavity of the water storage well 2, the valve plate 82 resets, sealing the left end of the connecting pipe 3, thereby preventing… The water source in the inner cavity of the water storage well 2 is recharged into the inner cavity of the irrigation canal 1. On rainy days, rainwater enters the inner cavity of the water storage well 2 through the guide holes on the surface of the protective cover 10 and the inner cavity of the guide groove 6, replenishing the water volume in the inner cavity of the water storage well 2. When irrigation is needed in the field, the submersible pump 72 is turned on to extract the water source in the inner cavity of the water storage well 2 and, under the action of the water delivery pipe 71, enters the inner cavity of the connecting pipe 73. Finally, the water source enters the inner cavity of multiple drip irrigation tapes 74 and is sprayed out from the water outlet nozzles 75, reducing the time the water source is exposed to the outside world, thereby reducing the evaporation of the water source.

[0027] In summary, this water-saving irrigation equipment, through the combined use of irrigation canal 1, water storage well 2 and connecting pipe 3, stores irrigation water or rainwater. At the same time, with the cooperation of water supply component 7, the stored water is precisely irrigated to the fields, thereby effectively reducing the evaporation of irrigation water and ensuring accurate water delivery.
