Description

Technical Field

[0001] This utility model relates to the field of environmental engineering technology, and in particular to a rainwater harvesting and irrigation device. Background Technology

[0002] Irrigation devices mainly refer to devices that apply irrigation water to water the vegetation in photovoltaic projects. They are widely used and play a significant role in the field of vegetation restoration in photovoltaic projects.

[0003] However, existing irrigation systems have low rainwater collection efficiency. In most cases, rainwater is directly lost and cannot be effectively collected and stored. Even if some collection facilities exist, they lack effective filtration and purification of the collected rainwater, making it unusable for irrigation and resulting in a waste of water resources. In addition, rainwater in photovoltaic project areas may carry impurities such as sand and dust and pollutants. The filtration systems of ordinary irrigation devices are simple and difficult to effectively remove these impurities. Long-term use of unfiltered water for irrigation will lead to clogged irrigation nozzles and scale buildup in pipes, reducing the service life and operating efficiency of the irrigation system, while also affecting the normal growth of vegetation.

DETAILED DESCRIPTION

[0036] Exemplary embodiments of the present application will be described hereinafter with reference to the accompanying drawings. While exemplary embodiments of the present application are illustrated, it should be understood that the present application can be embodied in many forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0037] As Figure 1 shown, the embodiment of the utility model provides a rainwater collection irrigation device, comprising:

[0038] Water tank 1, the inside fixed connection of water tank 1 has multilayer filter device,

[0039] A filter box 2 is fixedly connected to the water tank 1 via a guide pipe 302, and the filter box 2 is provided with multiple sets of filter components 3;

[0040] The acquisition component 4 is located on the top of the filter box 2 and is fixedly connected to the filter box 2.

[0041] In this embodiment, the collection component 4 collects rainwater and transports it to the filter box 2. The filter box 2 is equipped with multiple sets of filter components 3, which filter the received rainwater multiple times to remove impurities. The filtered rainwater is then sent to the water tank 1 through the guide pipe 302. Simultaneously, the multi-layer filtration device inside the water tank 1 filters the received rainwater again, obtaining rainwater suitable for irrigation. This irrigation-grade rainwater is then discharged through the outlet device at the bottom of the water tank 1 for irrigation. This rainwater collection and irrigation device effectively solves the problems of low rainwater collection and utilization rates and low filtration efficiency in existing irrigation devices. It improves rainwater collection and utilization rates and the quality of irrigation water, which is beneficial for energy conservation, environmental protection, and promoting normal vegetation growth.

[0042] In an optional embodiment of this utility model, the acquisition component 4 includes:

[0043] Collection trough 401, which is formed by multiple side walls, and the top and bottom of collection trough 401 are open;

[0044] An expansion plate 402 is connected to each side wall of the collection tank 401 via a telescopic assembly, and the number of expansion plates 402 is equal to the number of side walls of the collection tank 401;

[0045] A second filter 409 is rotatably connected to the top of one of the side walls of the collection tank 401.

[0046] In this embodiment, as Figure 2 As shown, the collection trough 401 is preferably formed by four side walls, forming an inverted truncated pyramid shape. The top of the collection trough 401 is open, and a second filter screen 409 covers it. The bottom of the collection trough 401 is connected to the filter box 2, allowing the collected rainwater to flow into the filter box 2. The inverted truncated pyramid design of the collection trough 401 allows rainwater to naturally slide down the inclined side walls of the collection trough 401 into the filter box 2, thereby improving rainwater collection efficiency. Figure 1As shown, the sidewall of each collecting groove 401 is connected with an expansion plate 402 through a telescopic assembly, and the inclination angle of the expansion plate 402 can be adjusted through the telescopic assembly. When the inclination angle of the expansion plate 402 relative to the vertical plane becomes larger, the opening angle of the collecting assembly 4 becomes larger, and more rainwater can be collected. Conversely, when the inclination angle of the expansion plate 402 relative to the vertical plane becomes smaller, the opening angle of the collecting assembly 4 becomes smaller, and the range of collected rainwater becomes smaller.

[0047] The second filter screen 409 is arranged on the top of the collecting groove 401 and is used for filtering the rainwater collected by the expansion plate 402. The second filter screen 409 can be opened in rotation, and impurities on the surface of the second filter screen 409 can be removed conveniently.

In the initial state, the expansion plate 402 is close to the outer surface of the collecting groove 401. When it is needed to expand the rainwater collecting area, the electric push rod 405 is elongated, the expansion plate 402 is pushed to rotate downward around the connecting point with the collecting groove 401, the caliber of the expansion plate 402 is lifted, and the effect of increasing the collecting range is realized. When it is needed to reduce the rainwater collecting area, the electric push rod 405 is shortened, the expansion plate 402 is pushed to rotate upward around the connecting point with the collecting groove 401, the caliber of the expansion plate 402 is lowered, and the effect of reducing the collecting range is realized.

[0053] In an optional embodiment of the utility model, the filtering device comprises:

[0055] An activated carbon 304 arranged in the double-layer partition plate 303 and having the size of the cross section equal to that of the double-layer partition plate 303.

[0056] In the embodiment, as shown in Figure 3 and Figure 4As shown, the filter device in the water tank 1 comprises a double-layer partition plate 303 and activated carbon 304 arranged inside the double-layer partition plate 303. The double-layer partition plate 303 and the activated carbon 304 are arranged in a sandwich structure.

[0060] In the embodiment, as shown in the figure, Figure 3 Preferably, two groups of filter assemblies 3 are arranged in the filter box 2, and each group of filter assemblies 3 is in sliding connection with the inner wall of the filter box 2. When the rainwater collected by the collection assembly 4 enters the inside of the filter box 2, the first filter screen 301 of the upper and lower filter assemblies 3 preliminarily filters and intercepts the impurities in the rainwater. The first filter screen 301 can be pulled out for cleaning after long-time use. Meanwhile, the closed end of the first filter screen 301 is provided with a flexible pad 308, which plays a sealing role, prevents the rainwater not filtered by the first filter screen 301 from directly leaking from the end, and ensures that the rainwater can be effectively filtered by the first filter screen 301.

One end of the electric telescopic rod 307 is fixedly connected to the lower surface of the fixing plate 306, and the output end of the electric telescopic rod 307 is fixedly connected to the upper surface of the blocking plate 305. The blocking plate 305 extends into the guide pipe 302, and when the output end of the electric telescopic rod 307 moves up and down, the blocking plate 305 is driven to move up and down in the guide pipe 302, so that the cross-sectional area of the guide pipe 302 through which rainwater flows changes. When the electric telescopic rod 307 is elongated or shortened, the blocking plate 305 is driven to move up and down in the guide pipe 302, thereby achieving control of the water flow in the guide pipe 302. The speed and flow of rainwater flowing into the water tank 1 can be adjusted according to actual needs, thereby achieving the effect of adjusting the flow.

[0067] In an optional embodiment of the utility model, the rainwater collecting and irrigating device further comprises:

[0068] A handrail 801 and a plurality of support columns 5 fixedly connected to the top of the water tank 1;

[0076] The working principle of this utility model is described in detail below with reference to the accompanying drawings:

[0077] like Figure 1 As shown, when the rainwater harvesting irrigation device is in use, rainwater is first collected using the collection trough 401. Before the rainwater falls into the collection trough 401, the second filter screen 409 outside the collection trough 401 initially filters out larger impurities in the rainwater. When it is necessary to expand the collection area, the electric push rod 405 extends, pushing the expansion plate 402 to rotate and open around the connection point with the collection trough 401, increasing the diameter of the collection trough 401 and thus increasing the collection range. After collecting rainwater for a long time, the first motor 408 can be started to drive the rotating rod 407 to rotate the second filter screen 409, causing impurities on the second filter screen 409 to slide off, thus cleaning the second filter screen 409. During this process, the expansion plate 402, which rotates in a direction similar to that of the second filter screen 409, can be appropriately retracted towards the side surface of the collection trough 401 to avoid motion interference. Filtered rainwater flows from the output of collection tank 401 into filter box 2, where it is filtered again by the first filter screen 301. It then temporarily settles within the filter box 2. Afterward, the electric telescopic rod 307 is activated to raise the baffle plate 305, allowing the rainwater to flow through the guide pipe 302 to water tank 1. The flow rate can be controlled by adjusting the fit between the baffle plate 305 and the guide pipe 302. The rainwater flowing into water tank 1 is further purified by the activated carbon 304 between the double-layer partitions 303 before being stored. Once the rainwater is treated, the second motor 702 is activated to drive the tires 703, moving the device to the irrigation area. Alternatively, the device can be pushed to the irrigation area via the handle 801. Upon reaching the irrigation area, water from water tank 1 can be used for irrigation. Throughout the entire process, the solar panel 6 provides some energy for the device's operation, achieving energy-saving and environmentally friendly irrigation using new energy sources.

[0078] The above embodiment of the utility model, through the expansion plate 402 and electric push rod 405 in acquisition subassembly 4, can flexibly expand the caliber of collecting groove 401, improve the rainwater collection range. The second screen 409 on collecting groove 401 can not only filter larger impurities before the rain, but also can rotate and slide impurities to realize self-cleaning under the drive of first motor 408, and the cooperation of the two not only improves the collection and utilization rate of rainwater, reduces water resource waste, provides more sufficient water source for vegetation irrigation, and improves the problem of insufficient rainwater collection of the existing device. The first screen 301 in the filter box 2 is connected with sliding for easy cleaning, the flexible pad 308 at the closed end connection ensures effective rainwater filtration, the blocking plate 305 in the guide pipe 302 below the first screen 301 cooperates with the electric telescopic rod 307 to accurately adjust the speed and flow of rainwater flowing into the water tank 1, the activated carbon 304 in the water tank 1 further purifies the rainwater, improves water quality, realizes efficient filtration of impurities in rainwater and accurate control of water flow, ensures clean irrigation water, avoids impurities from blocking the irrigation system, and improves the promoting effect of irrigation water on vegetation growth.

[0079] The above is the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the protection scope of the utility model.
