Description

Technical Field

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

[0002] With the continuous advancement of urbanization, the efficient collection and recycling of rainwater resources are becoming increasingly important in alleviating urban water pressure and mitigating urban flooding disasters.

[0003] Existing traditional rainwater harvesting devices on the market generally adopt an open collection structure, which has certain shortcomings in actual use: 1. The inlet of traditional collection devices is mostly a flat or simple inclined structure. It is acceptable for collecting vertical rainfall, but it is prone to splashing and loss of oblique rainfall under the action of wind, resulting in a significant decrease in collection efficiency; 2. Rainwater often carries solid impurities such as leaves, mud, and dead branches. The filter screen of existing devices is mostly set in a flat or fixed angle, and impurities are easily trapped and accumulated, causing the filter screen to become clogged, requiring frequent manual cleaning. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rainwater harvesting and utilization device, and the technical solution adopted is as follows:

[0005] A rainwater harvesting and utilization device includes a collection cylinder, a water storage chamber for collecting water is provided inside the collection cylinder, a circular opening is provided at the center of the collection cylinder, a rain-blocking plate is provided at the upper end of the collection cylinder, a connecting rod is provided at the center below the rain-blocking plate that can penetrate into the central opening of the collection cylinder, a spiral frame is provided at the lower end of the connecting rod, and a filter screen is laid on top of the spiral frame.

[0006] The cross-section of the spiral frame at a single location is a U-shaped structure. The outer side of the spiral frame is hollowed out, and a water inlet groove for connecting to the water storage chamber is opened in the opening of the collection cylinder. The water inlet groove corresponds to the hollowed-out position on the outer side of the spiral frame.

[0007] Furthermore, a funnel-shaped chamfer is provided at the upper end of the opening inside the collection cylinder, and the funnel-shaped opening can increase the rainwater collection area.

[0008] Furthermore, an outwardly expanding conical base is provided at the lower end of the collection cylinder, and a pull-out garbage bin is provided on one side inside the base. Multiple through holes are opened at the bottom of the garbage bin. The garbage bin can be used to collect impurities and debris intercepted by the filter screen. Under the action of the through holes, rainwater accumulated in the garbage bin can be drained, thereby reducing the moisture content in the garbage bin and reducing the risk of odor generation and mosquito and fly breeding.

[0009] Furthermore, the rain-blocking plate adopts a cross-shaped structure, and each side of the vertical plate in the rain-blocking plate is provided with a concave arc-shaped groove. The concave arc-shaped groove can utilize the principle of curved surface guidance to collect the obliquely impacting rainwater along the groove surface to the funnel-shaped opening in the center of the collection cylinder, reducing the rebound and loss of rainwater on the surface of the rain-blocking plate.

[0010] Furthermore, one end of the rain-blocking plate is provided with a protruding plate, which is connected to the collecting cylinder by bolts, so as to realize the installation and fixation of the rain-blocking plate. Using the openings for installing bolts on the upper surface of the collecting cylinder and the protruding plate as a reference, it can be ensured that the hollow side of the spiral frame corresponds strictly with the position of the water inlet groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention increases the rainwater collection area through the funnel-shaped opening at the top of the collection cylinder. Simultaneously, the rain-blocking plate installed at the top of the collection cylinder, with its cross-shaped structure and concave arc-shaped side plates, guides rainwater from any direction, allowing it to slide down the surface of the rain-blocking plate to the funnel-shaped opening. This prevents rainwater from splashing and being lost due to wind, and guides more rainwater to slide down the plate surface to the funnel-shaped opening, creating a synergistic effect with the funnel structure to further improve rainwater collection efficiency.

[0013] This invention features a filter screen installed above a spiral frame that effectively intercepts larger particles and debris in rainwater. The filter screen, like the spiral frame, has a spiral structure. When rainwater carrying impurities impacts the filter screen, the spiral shape guides the intercepted impurities to slide automatically downwards along the spiral trajectory, ultimately falling into the trash can below. This prevents impurities from accumulating and clogging the filter screen. Furthermore, during this process, rainwater continuously passes through the filter screen into the water storage chamber, achieving efficient separation of impurities and rainwater and improving water resource utilization.

[0014] In cases of heavy rainfall, even if rainwater is not fully filtered, some of it can still drain through the holes at the bottom of the trash can after entering the lower trash can. This reduces the moisture content inside the trash can and lowers the risk of odor and mosquito / fly breeding.

[0015] This invention achieves stable fixing of the rain-blocking plate by setting a protruding plate at one end of the cross-shaped rain-blocking plate and connecting it to the collection cylinder with bolts. It also ensures the accurate positioning of the connecting rod and the spiral frame connected to it, so that the outer hollow of the spiral frame can accurately correspond to the water inlet groove, ensuring that rainwater can flow smoothly into the water storage cavity through the water inlet groove.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As attached Figure 1-7 As shown.

[0027] A rainwater harvesting and utilization device includes a circular collection cylinder 1, with an outwardly expanding conical base at the lower end of the collection cylinder 1, which can enhance the stability of the entire collection cylinder when placed.

[0028] As attached Figure 2 As shown, a water storage cavity 11 for collecting water is provided inside the collecting cylinder 1. A circular opening that is open from top to bottom is opened at the center of the collecting cylinder 1. A funnel-shaped chamfer is provided at the upper end of the opening. Based on this structure, the funnel-shaped opening can increase the rainwater collection area.

[0029] Furthermore, a cross-shaped rain-blocking plate 4 is provided at the upper end of the collection cylinder 1, and a connecting rod 5 is provided at the center position below the rain-blocking plate 4, which can penetrate into the central opening inside the collection cylinder 1. A spiral bracket 6 is provided at the lower end of the connecting rod 5, as shown in the attached figure. Figure 2 , 4 As shown, the cross-section of the spiral frame 6 at a single position is a U-shaped structure. The outer side of the spiral frame 6 is hollowed out. A water inlet trough 12 is provided in the center opening of the collecting cylinder 1 and corresponding to the hollowed-out position of the spiral frame 6 for connecting the water storage chamber 11. Specifically, the water inlet trough 12 corresponds to the hollowed-out position on the outer side of the spiral frame 6.

[0030] As attached Figure 5 , 7 As shown, a filter screen 7 is laid above the spiral frame 6. Based on the above structure, the working principle of this device is as follows: when rainwater falls vertically, the water flow can directly enter the opening inside the collection cylinder 1 through the funnel-shaped opening at the top of the collection cylinder 1; when rainwater falls obliquely under the action of wind, the cross-shaped rain-blocking plate 4 can block most of the oblique rainwater, allowing the rainwater to slide down the rain-blocking plate to the funnel-shaped opening of the collection cylinder 1.

[0031] The collected rainwater flows downwards and falls onto the filter screen 7 on the spiral frame 6. Larger particles of impurities or debris are blocked by the filter screen 7 and can rotate downwards along the surface of the filter screen 7, eventually falling into the garbage bin 2 located at the lower end of the collection cylinder 1. The garbage bin 2 has a pull-out structure and can be removed periodically for cleaning.

[0032] Rainwater filtered by the filter screen 7 falls into the inner side of the spiral frame 6. Since the outer side of the spiral frame 6 is hollow and corresponds to the water inlet trough 12, the rainwater can flow into the water storage chamber 11 inside the collection cylinder 1 through the water inlet trough 12 and be stored. When the collected rainwater needs to be used, the rainwater in the water storage chamber 11 can be drawn out and used through the drain pipe 3 connected to the lower end of the collection cylinder 1.

[0033] Further details are attached. Figure 2 As shown, a through hole is provided at the bottom of the trash can 2 to facilitate the drainage of rainwater accumulated inside the trash can 2, and to prevent rainwater from soaking the trash inside the trash can for a long time, which could breed bacteria and mosquitoes.

[0034] Furthermore, each side of the central plate of the rain barrier 4 is designed with a concave arc structure. This structural design can reduce the splashing of oblique rainwater hitting the surface of the rain barrier and improve the rainwater collection efficiency.

[0035] Furthermore, to ensure that the cutouts on the outer side of the spiral frame 6 correspond to the water inlet trough 12 during installation, a protruding plate is provided at one end of the cross-shaped rainproof plate 4, as shown in the attached figure. Figure 6As shown, the convex plate is connected to the collecting cylinder 1 by bolts, and corresponding openings for installing bolts are provided on the upper surface of the collecting cylinder 1 and inside the convex plate.

[0036] During installation, bolts are passed through the openings of the convex plate and fixed to the corresponding positions of the collecting cylinder 1, which can fix the rainproof plate 4 and ensure that the connecting rod 5 and the spiral frame 6 connected to it are accurately positioned, so that the outer hollow of the spiral frame 6 corresponds precisely to the water inlet trough 12.

[0037] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
