Description

Technical Field

[0001] This application relates to the technical field of irrigation equipment, and in particular to a water-saving irrigation device for vegetation restoration. Background Technology

[0002] Vegetation restoration is one of the core aspects of ecological environment governance and is widely used in desertification control, mine ecological restoration, highway and railway slope protection, and reforestation. These scenarios often face common problems such as water scarcity, uneven rainfall distribution, and complex terrain. Therefore, water-saving irrigation technology has become a key support for ensuring the survival and growth of vegetation.

[0003] The current vegetation restoration irrigation mainly relies on fixed-volume water storage tanks or direct access to municipal water sources. Fixed-volume water storage tanks cannot flexibly adjust the water storage space according to rainfall. When there is heavy rainfall, rainwater is easily lost due to insufficient space inside the tank. During dry periods, it is difficult to maintain continuous irrigation due to limited water storage. Especially in ecological restoration areas with unstable rainfall, the contradiction between water waste and insufficient supply is prominent. Furthermore, in vegetation restoration scenarios, natural precipitation often contains impurities such as mud, sand, dead branches, fallen leaves, and insect excrement; existing irrigation devices are mostly fixed integrated designs, and impurities easily accumulate on the filter screen, making them difficult to disassemble and clean. Utility Model Content

[0004] In order to achieve automatic adaptive adjustment of water storage space, efficient use of water resources, and alleviate the problem of supply and demand contradiction, this application provides a water-saving irrigation device for vegetation restoration.

[0005] This application provides a water-saving irrigation device for vegetation restoration, which adopts the following technical solution: it includes a water tank and a top cover.

A float is installed at the lower end of the inner side of the top cover. A guide plate is provided at the upper end of the top cover. A filter component is installed inside the guide plate.

[0006] Optionally, the telescopic component includes a folded fabric, the two ends of which are fixedly connected to the upper end of the water tank and the lower end of the top cover with sealant, respectively, and the top cover and the outside of the water tank are provided with guides.

[0007] Optionally, the guide component includes a guide rod and a limiting plate. The upper end of the guide rod is fixedly installed on the top cover; the limiting plate is installed on the water tank; the lower end of the guide rod is slidably disposed with the limiting plate; multiple guide rods and limiting plates are provided, and the multiple guide rods and limiting plates are evenly distributed.

[0008] Optionally, the limiting plate is provided with scale lines, and a pointer is provided on one side of the scale lines. The pointer is installed at the lower end of the guide rod and is slidably disposed with the limiting plate. An observation window is provided on the water tank on one side of the limiting plate.

[0009] Optionally, the guide plate is tapered, and one side of the lower end of the guide plate is rotatably connected to the top cover via a hinge, while the other side of the lower end of the guide plate is provided with a buckle between it and the top cover.

[0010] Optionally, the filter assembly includes a filter box, a filter plate is provided inside the filter box, a positioning groove is provided on the outside of the filter box, a positioning block is installed on the inner wall of the guide plate at the corresponding position of the positioning groove, the positioning block is inserted into the positioning groove, and the positioning block and the positioning groove are fixedly connected by fixing bolts.

[0011] Optionally, a flow regulating valve is installed on the water outlet pipe, and the end of the water outlet pipe away from the water storage tank is connected to a drip irrigation pipe, which has several drip irrigation heads spaced apart along its length.

[0012] In summary, this application includes the following beneficial technical effects: 1. This utility model forms an adaptive adjustment structure through the telescopic component between the water tank and the top cover, and the float on the inner side of the top cover: when it rains, the water level in the tank rises, causing the float to float up, and the top cover moves up accordingly. The folded cloth unfolds to expand the water storage volume, preventing rainwater from overflowing and being lost due to limited space; during dry periods, the water level drops, the top cover sinks with the float, and the folded cloth contracts, reducing the water storage space synchronously, reducing the contact area between the stored water and the air, and reducing water evaporation loss; balancing rainfall collection and drought water supply needs, alleviating the problem of water waste and insufficient supply in vegetation restoration scenarios, and improving water resource utilization efficiency.

[0013] 2. This utility model adopts a modular filtration design. The filter box is connected to the positioning groove on the inner wall of the guide plate by a positioning block and reinforced with fixing bolts. At the same time, the guide plate is rotatably connected to the top cover by a hinge and is opened and closed by a buckle. When cleaning the surface, it is only necessary to open the buckle and rotate the guide plate to rotate the filter box, which facilitates cleaning by the staff. By removing the fixing bolts, the filter box can be removed for internal impurity cleaning or component replacement, reducing the maintenance cost and operation difficulty of the device in complex vegetation restoration scenarios.

The drip irrigation pipe is provided with several drip irrigation heads at intervals along its length. A telescopic component is provided between the water tank 1 and the top cover 3. The telescopic component includes a folded cloth 6, which is made of PVC coated nylon cloth.

[0018] See Figure 2 As shown, the two ends of the folded cloth 6 are fixedly connected to the upper end of the water tank 1 and the lower end of the top cover 3 with sealant. The top cover 3 and the outside of the water tank 1 are provided with guide components, including guide rod 7 and limiting plate 8. The upper end of the guide rod 7 is fixedly installed on the top cover 3; the limiting plate 8 is installed on the water tank 1, and the lower end of the guide rod 7 is slidably set with the limiting plate 8. The guide rod 7 and the limiting plate 8 are made of 304 stainless steel. The sliding contact surface of the guide rod 7 and the limiting plate 8 is coated with silicone-based grease and replenished once every 3 months to prevent sand and dust from entering and causing jamming.

[0019] See Figure 1 As shown, there are multiple guide rods 7 and limiting plates 8. The multiple guide rods 7 and limiting plates 8 are evenly distributed. The limiting plate 8 is provided with a scale line 9. A pointer 10 is provided on one side of the scale line 9. The pointer 10 is installed at the lower end of the guide rod 7 and slides with the limiting plate 8. An observation window 11 is provided on the water tank 1 on one side of the limiting plate 8. The observation window 11 is made of transparent acrylic sheet with a scratch-resistant film coated on the surface.

[0020] See Figure 2 , Figure 3 , Figure 4As shown, a float 17 is installed on the lower inner side of the top cover 3. The float 17 is made of closed-cell EVA foam. A guide plate 4 is provided on the upper part of the top cover 3. The guide plate 4 is conical. One side of the lower end of the guide plate 4 is rotatably connected to the top cover 3 by a hinge 12. A buckle 13 is provided between the other side of the lower end of the guide plate 4 and the top cover 3. A filter assembly is installed inside the guide plate 4. The filter assembly includes a filter box 5. A filter plate is provided inside the filter box 5. The filter plate adopts a multi-layer composite structure, with an outer nylon mesh, a middle activated carbon, and an inner PP cotton.

[0021] See Figure 2 , Figure 3 , Figure 4 As shown, a positioning groove 15 is provided on the outside of the filter box 5. A positioning block 14 is installed on the inner wall of the guide plate 4 at the corresponding position of the positioning groove 15. The positioning block 14 is inserted into the positioning groove 15. The positioning block 14 and the positioning groove 15 are fixedly connected by a fixing bolt 16. The fixing bolt 16 and the hinge 12 are made of 316 stainless steel.

[0022] The implementation principle of a water-saving irrigation device for vegetation restoration according to an embodiment of this application is as follows: During non-rainfall and non-irrigation periods, the device is in standby mode. At this time, the water tank 1 contains a certain initial amount of water. The top cover 3 is in a low position due to the low water level inside the tank and the gravity of the float 17 and its own weight. When it rains, the rain falls onto the conical guide plate 4, guiding the rainwater to converge at the center of the guide plate 4. After the converged rainwater is intercepted by the filter plate in the filter box 5, impurities such as mud, sand, dead branches, fallen leaves, and insect excrement mixed in the rainwater are blocked on the surface of the filter plate. The filtered clean rainwater flows into the water tank 1 through the filter box 5. As clean rainwater continues to be injected, the water level in the storage tank 1 gradually rises, and the float 17 floats upward under the action of buoyancy, which in turn drives the top cover 3 to move upward in sync. During the upward movement of the top cover 3, the guide rod 7 connected to its outer side slides vertically along the limiting plate 8, and the pointer 10 moves with the guide rod 7. The staff can visually read the water level change through the scale line 9 on the limiting plate 8, and at the same time, they can use the observation window 11 of the storage tank 1 to help observe the water level in the tank. According to the needs of vegetation growth, the staff adjusts the flow regulating valve on the water outlet pipe 2 to control the irrigation water flow rate; the clean water stored in the water tank 1 flows into the drip irrigation pipe through the water outlet pipe 2, and then through the drip irrigation heads set at intervals along the length of the drip irrigation pipe, it is slowly and evenly delivered to the roots of the vegetation in the form of drip irrigation; as irrigation continues, the water level in the water tank 1 gradually decreases, the buoyancy of the float 17 decreases and sinks with the water level, causing the top cover 3 to move down synchronously; during the downward movement of the top cover 3, the guide rod 7 slides down along the limiting plate 8, the folded cloth 6 gradually contracts as the top cover 3 descends, and the water storage space of the water tank 1 decreases synchronously; When initial cleaning of the filter box 5 is required, the operator first uses clip 13, then drives the guide plate 4 to rotate outward around hinge 12 to directly clean the impurities attached to the inner wall of the guide plate 4 and the surface of the filter box 5. For deep cleaning and replacement, unscrew the fixing bolt 16; pull the filter box 5 out of the positioning groove 15 on the inner wall of the guide plate 4, remove the filter plate inside the filter box 5 for thorough cleaning, or directly replace it with a new filter plate; after cleaning or replacement, align and insert the positioning groove 15 of the filter box 5 with the positioning block 14 of the guide plate 4, and tighten the fixing bolt 16; then rotate the guide plate 4 back to its original position around hinge 12 and fasten clip 13 to complete the maintenance.

[0023] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
