Technical Field
[0001] This utility model relates to the field of greenhouse planting technology, specifically a water-saving irrigation device. Background Technology
[0002] Greenhouse cultivation is a modern agricultural technology that utilizes artificially constructed, heat-insulating, and light-transmitting facilities (such as plastic greenhouses and glass greenhouses) to regulate the internal environment and achieve off-season or high-efficiency cultivation of crops. By using covering materials to isolate the crops from external climate influences, the greenhouse can maintain stable temperature, humidity, and light conditions, extending the crop's growing season or enabling year-round production. This technology is widely used in the cultivation of high-value-added crops such as vegetables, flowers, and fruits, effectively protecting against natural risks such as frost, heavy rain, and pests, thereby improving yield and quality. Simultaneously, greenhouses can be combined with precision agriculture technologies such as drip irrigation and hydroponics to conserve water and fertilizer resources.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4This utility model provides an embodiment of a water-saving irrigation device, including a planting greenhouse 1. Rainwater collection boxes 2 are fixedly connected to the lower ends of both sides of the planting greenhouse 1. A barrier net 201 is fixedly connected to the upper middle part of the interior of the rainwater collection box 2. The barrier net 201 blocks debris and leaves falling into the rainwater collection box 2, allowing rainwater to pass through the barrier net 201 and enter the rainwater collection box 2 for storage. Guide rods 3 are fixedly installed inside the rainwater collection box 2 on both sides of the upper middle part of the barrier net 201, with the two guide rods 3 connected together at the middle. A scraper 302 is attached, and the two guide rods 3 are fixedly connected to the inner wall of the rainwater collection tank 2 via a crossbar 301 at both ends. The lower end of the scraper 302 is in contact with the upper end of the barrier net 201. When there is a lot of debris on the upper end of the barrier net 201, the scraper 302 is pulled longitudinally to scrape off the debris and move it to the front or rear end of the rainwater collection tank 2. Guide tubes 303 are fixedly connected to both sides of the middle part of the scraper 302. The two guide rods 3 pass through the two guide tubes 303 respectively. When the scraper 302 moves, it moves along the guide tubes 303. The rod 3 slides for guidance. Discharge ports 202 are provided on both the front and rear ends of the rainwater collection box 2 and on the upper end of the barrier net 201. Baffles 203 are provided on the outer side of each discharge port 202. The upper end of the baffle 203 is connected to the rainwater collection box 2 via a hinge 204. When the scraper 302 moves debris to the front or rear end of the rainwater collection box 2, the baffle 203 is opened upwards via the hinge 204, allowing the debris to be discharged through the discharge ports 202. A common outlet 205 is provided between the lower middle part of the inner side of both rainwater collection boxes 2 and the planting greenhouse 1. Inside the greenhouse 1, control valves 206 are fixedly connected to both water outlets 205. Diversion pipes 6 are installed on both sides of the lower end of the greenhouse 1. Multiple irrigation pipes 601 are fixedly connected between the two diversion pipes 6. The two control valves 206 are connected to the two diversion pipes 6 through connecting pipes 207. The diversion pipes 6 and irrigation pipes 601 are buried underground. During the water shortage season, the control valves 206 are opened to allow rainwater in the two rainwater collection tanks 2 to be transported to the diversion pipes 6 and irrigation pipes 601 through the connecting pipes 207, thus achieving irrigation.
[0024] Please see Figure 2 and Figure 4The upper part of the rainwater collection box 2 is rotatably connected to a rotating plate 4. A rotating pipe 401 is fixedly connected to the middle of the rotating plate 4. A fixed shaft 402 is rotatably connected inside the rotating pipe 401. The front and rear ends of the fixed shaft 402 are fixedly connected to the front and rear end faces of the rainwater collection box 2, respectively. When it rains, the rainwater falling on the planting greenhouse 1 flows to both sides of the outer side of the planting greenhouse 1 and enters the upper part of the rainwater collection box 2. Then, the rainwater flows to one side of the upper part of the rotating plate 4. The upper part of the rotating plate 4 is rotated by the gravity of the rainwater, which opens the upper part of the rainwater collection box 2, allowing the rainwater to flow into the rainwater collection box 2. When the rain stops, the rotating plate 4 returns to its original position through its own gravity balance, closing the upper part of the rainwater collection box 2 and reducing the evaporation of the rainwater collected inside the rainwater collection box 2.
[0025] Please see Figure 2 and Figure 3 Both rainwater collection boxes 2 are fixedly connected to the side of the planting greenhouse 1 with triangular guide strips 5. Both sides of the inside of the planting greenhouse 1 are provided with pressing strips 101. The triangular guide strips 5 and the pressing strips 101 are fixedly connected by multiple screws 102. The triangular guide strips 5 are attached to the outside of the planting greenhouse 1 to guide rainwater into the rainwater collection box 2, preventing rainwater from falling through the gap between the rainwater collection box 2 and the planting greenhouse 1 and affecting rainwater collection.
[0026] Working Principle: During operation, rainwater flows along the roof of the planting greenhouse 1 to both sides and is guided by the triangular guide strips 5 into the rainwater collection tank 2. The rainwater impacts one side of the rotating plate 4, causing it to rotate downwards and opening the water inlet channel. After entering the tank, the barrier net 201 filters out leaves, debris, etc., and the clean rainwater is stored in the lower part of the tank. After the rain stops, the rotating plate 4 returns to its original position due to gravity, sealing the tank to reduce evaporation. When debris accumulates on the barrier net 201, the scraper 302 is manually pushed along the guide rod 3 to scrape the debris to the discharge port 202, and the baffle 203 can be opened for cleaning. When irrigation is needed, the control valve 206 is opened, and the stored rainwater flows through the connecting pipe 207 into the diversion pipe 6 and the irrigation pipe 601, permeating into the soil for precise water-saving irrigation. This device effectively avoids pipe blockage and improves rainwater utilization efficiency through its filtration, anti-evaporation, and debris removal functions.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
