Description

Technical Field

[0001] The utility model relates to the field of rainwater collection devices, in particular to a rainwater collection device for landscape gardening. Background Art

[0002] Landscape architecture, a discipline that integrates science, technology, and art, creates a safe, comfortable, healthy, and efficient living environment for humans by planning land, its materials, and spaces. During the greening process of landscape architecture, cultivated plants require regular watering and irrigation to ensure their normal growth. However, water resources are relatively scarce in some areas, with extremely uneven temporal and spatial distribution. Water resources vary greatly from year to year, with precipitation and runoff concentrated in the summer months. Consecutive years of high and low water levels alternate, resulting in frequent droughts and prominent water supply and demand imbalances in some areas. Therefore, a rainwater collection device is urgently needed to alleviate water pressure.

[0003] Patent CN218713490U discloses a rainwater collection device for landscape gardening, including a water collecting tank, a drain pipe, a water inlet limiting mechanism, a water collecting trough and a drain valve. A water inlet limiting mechanism is set between the water collecting tank and the water collecting trough, and a water gate structure is set in the water inlet limiting mechanism. The water inlet of the water collecting tank is limited by a gate plate inside the water gate structure, and a control mechanism is set on the left side of the water inlet limiting mechanism. A float is set at the bottom of the control mechanism. The position of the float is controlled by the water volume inside the water collecting tank, so that the float floats upward when the water volume inside the water collecting tank reaches a certain level, and the two gate plates are driven to close through the cooperation between the connecting rods to limit the water inlet of the water collecting tank. When the water volume in the water collecting tank reaches a certain level, the water inlet of the water collecting tank is automatically limited, thereby reducing the user's manual operation and increasing the automation effect of the rainwater collection device. The above patent sets a water inlet limiting mechanism between the water collecting tank and the water collecting trough, and a water gate structure is set in the water inlet limiting mechanism. The water inlet of the water collecting tank is limited by a gate plate inside the water gate structure, and a control mechanism is set on the left side of the water inlet limiting mechanism. A float is set at the bottom of the control mechanism, and the position of the float is controlled by the water volume inside the water collecting tank, so that the float floats upward after the water volume inside the water collecting tank reaches a certain level, and the two gate plates are driven to close through the cooperation between the connecting rods to limit the water inlet of the water collecting tank. After the water volume in the water collecting tank reaches a certain level, the water inlet of the water collecting tank is automatically limited, reducing the manual operation of the user and increasing the automation effect of the rainwater collection device. However, the filter used in the patent for filtering water is prone to algae after long-term use, which clogs the filter holes, making it inconvenient for rainwater to pass through the filter and flow through the pipe, thereby affecting the rainwater collection effect.

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0033] Example 1

[0034] In order to maintain the collection efficiency of the rainwater collection device for a long time, this embodiment provides a rainwater collection device for landscape gardening. Figure 1-6 ,include:

[0035] The infusion bin 1 is provided with a water inlet on the top and a water outlet on the bottom side. A water outlet pipe 5 is provided at the water outlet. The infusion bin 1 is connected to an external water reservoir through the water outlet pipe 5.

[0036] A coarse filter assembly is provided above the water inlet to remove debris;

[0037] A fine filter component installed in the water inlet is used to remove impurities and pollutants;

[0038] The cleaning component provided on the fine filter component is used to ensure the smooth flow of the fine filter component.

[0039] In order to remove larger debris, such as leaves, branches, etc., in this embodiment, the coarse filtering component includes a leaf net 3 arranged on the top of the infusion bin 1; the middle part of the leaf net 3 is arched to avoid accumulation of debris.

[0040] In this embodiment, a collecting bucket 2 is provided between the infusion bin 1 and the fallen leaf net 3 to connect the two. The large-diameter end of the collecting bucket 2 is connected to the fallen leaf net 3, and the small-diameter end is connected to the top of the infusion bin 1.

[0041] In order to remove smaller impurities and pollutants, in this embodiment, the fine filtration component includes a filter screen 7 arranged in the water inlet, and the filter screen 7 is abutted against the inner wall of the water inlet on all sides.

[0042] In order to clean the impurities and pollutants accumulated on the filter 7 and ensure the smooth flow of the filter 7, in this embodiment, the cleaning assembly includes: a fixed shell 4 arranged on the outer wall of the infusion bin 1, and a sealing plate 14 is provided on the side of the fixed shell 4 near the infusion bin 1; a reciprocating screw 9 arranged on the fixed shell 4 along the length direction of the fixed shell 4; a drive motor 8 arranged at the end of the reciprocating screw 9; a slider 11 sleeved on the reciprocating screw 9; a moving ring 10 arranged on the outer wall of the slider 11, an adapter column 13 passing through the sealing plate 14, a transmission gear 16 is provided in the middle of the adapter column 13, and the transmission gear 16 is meshed with a rack plate 17 arranged on the bottom surface of the fixed shell 4. One end of the adapter column 13 is connected to the cleaning wheel 15 arranged on the upper surface of the filter 7, and the other end is rotatably connected to the moving ring 10.

[0043] Specifically, when the filter 7 needs to be cleaned, the drive motor 8 is first started to drive the connected reciprocating screw 9 to rotate. As the reciprocating screw 9 rotates, the slider 11 starts to move, thereby driving the moving ring 10 fixed on the slider 11 to reciprocate inside the fixed shell 4. During the movement of the adapter column 13 of the moving ring 10, the transmission gear 16 connected to the adapter column 13 starts to rotate. The transmission gear 16 further drives the cleaning wheel 15 to rotate through the action of the rack plate 17. At the same time, the sealing plate 14 ensures the sealing between the fixed shell 4 and the infusion bin 1 to prevent moisture or impurities from leaking out. While the cleaning wheel 15 moves, it continues to rotate to effectively clean the algae, dirt and other impurities on the filter 7, thereby keeping the filter 7 unobstructed and ensuring that its filtering effect is not affected.

[0044] In this embodiment, the rainwater collection device further includes a support assembly arranged on the bottom surface of the infusion bin 1 , and the support assembly includes a support column 24 arranged at the bottom of the infusion bin 1 , and a reinforcing rib 25 arranged between the infusion bin 1 and the support column 24 .

[0045] In this embodiment, the rainwater collection device further includes a clamping assembly, and the support column 24 has a mounting cavity;

[0046] The clamping assembly includes: a screw 6, which extends into the installation cavity along the length direction of the support column 24; a movable plate 18 arranged in the installation cavity, and the movable plate 18 is threadedly connected to the screw 6; a plurality of cone plates 19 arranged on the side of the movable plate 18; a plurality of clamping structures, and the plurality of clamping structures are arranged at intervals from top to bottom, and the clamping structure includes: a connecting shell 12 arranged on the outer side of the support column 24; a return spring 23 arranged on the side of the connecting shell 12 facing the support column 24; a tooth plate 20 arranged on the side of the return spring 23 facing the support column 24, and the tooth plate 20 extends into the installation cavity with one end being conical and abutting against the corresponding cone plate 19; two gear columns 21 respectively arranged on both sides of the connecting shell 12, and the two gear columns 21 are respectively meshed and connected with the tooth plate 20; two clamping semi-rings 22 respectively arranged on the side of the two gear columns 21 away from the tooth plate 20, and the concave surfaces of the two clamping semi-rings 22 are arranged opposite to each other to form a clamping space.

[0047] Specifically, during the installation process, when the screw 6 rotates, it will drive the movable plate 18 to move in the specified direction. As the movable plate 18 moves, the cone plate 19 acts on the toothed plate 20, pushing it to move in the connecting shell 12. The movement of the toothed plate 20 then drives the gear column 21 to rotate. As the gear column 21 rotates, the clamping ring 22 gradually opens to both sides. At this time, the clamping ring 22 can be sleeved on the target installation position to ensure that the device is accurately positioned. Once the clamping ring 22 is successfully fixed on the installation position, the screw 6 is rotated in the opposite direction. At this time, the screw 6 will drive the movable plate 18 to move in the opposite direction. The return spring 23 pushes the toothed plate 20 to move in the opposite direction under the action of the elastic force. The reverse movement of the toothed plate 20 drives the clamping ring 22 to retract through the gear column 21, thereby firmly clamping the installation position to ensure the stable installation of the equipment.

[0048] Working principle: When it rains, rainwater passes through the leaf net 3 and falls into the collection bucket 2, then flows into the infusion bin 1, and is filtered again by the filter screen 7, so that the rainwater flows out to the external water tank through the drain pipe 5, so that the rainwater can be used by users. When the filter screen 7 needs to be cleaned, the drive motor 8 is started to drive the reciprocating screw 9 to rotate, so that the reciprocating screw 9 drives the moving ring 10 to move back and forth along the fixed shell 4 through the slider 11, and the transmission gear 16 connected to the adapter column 13 at the moving ring 10 rotates during the movement of the adapter column 13. The transmission gear 16 rotates the cleaning wheel 15 through the rack plate 17, and the sealing plate 14 maintains a seal between the fixed shell 4 and the infusion bin 1, so that the cleaning wheel 15 rotates while moving. The algae or other impurities at the filter screen 7 are cleaned, thereby ensuring the use effect of the filter screen 7. During the installation process, when the screw 6 rotates, the screw 6 drives the movable plate 18 to move, so that the movable plate 18 allows the tooth plate 20 to move in the connecting shell 12 through the cone plate 19, thereby driving the gear column 21 to rotate through the movement of the tooth plate 20, so that the gear column 21 allows the clamping ring 22 to open to both sides. After the clamping ring 22 is sleeved on the installation location, the screw 6 is rotated in the opposite direction again, so that the screw 6 drives the movable plate 18 to move back, so that the reset spring 23 allows the tooth plate 20 to move in the opposite direction through the elastic force, so that the tooth plate 20 drives the clamping ring 22 to clamp the installation location through the gear column 21, thereby facilitating the installation of the device.

The initially filtered rainwater then flows to an infusion bin 1 for further storage and processing. A filter 7 is installed within the infusion bin to provide a more detailed filtration, removing smaller impurities and contaminants. The filtered rainwater then flows out through a drain pipe 5 and enters the water storage system or is directly supplied to users.

[0053] Specifically: when the filter 7 needs to be cleaned, the drive motor 8 is first started to drive the connected reciprocating screw 9 to rotate. As the reciprocating screw 9 rotates, the slider 11 starts to move, thereby driving the moving ring 10 fixed on the slider 11 to reciprocate inside the fixed shell 4. During the movement of the adapter column 13 of the moving ring 10, the transmission gear 16 connected to the adapter column 13 starts to rotate. The transmission gear 16 further drives the cleaning wheel 15 to rotate through the action of the rack plate 17. At the same time, the sealing plate 14 ensures the sealing between the fixed shell 4 and the infusion bin 1 to prevent moisture or impurities from leaking out. While the cleaning wheel 15 moves, it continues to rotate to effectively clean the algae, dirt and other impurities on the filter 7, thereby keeping the filter 7 unobstructed and ensuring that its filtering effect is not affected.

[0055] Specifically: during the installation process, when the screw 6 rotates, it will drive the movable plate 18 to move in the specified direction. As the movable plate 18 moves, the cone plate 19 acts on the toothed plate 20, pushing it to move in the connecting shell 12. The movement of the toothed plate 20 then drives the gear column 21 to rotate. As the gear column 21 rotates, the clamping half ring 22 gradually opens to both sides. At this time, the clamping half ring 22 can be sleeved on the target installation position to ensure that the device is accurately positioned. Once the clamping half ring 22 is successfully fixed on the installation position, the screw 6 is rotated in the opposite direction. At this time, the screw 6 will drive the movable plate 18 to move in the opposite direction.

Algae or other impurities are cleaned, thereby ensuring the use effect of the filter 7. During the installation process, when the screw 6 rotates, the screw 6 drives the movable plate 18 to move, so that the movable plate 18 allows the tooth plate 20 to move in the connecting shell 12 through the cone plate 19, thereby driving the gear column 21 to rotate through the movement of the tooth plate 20, so that the gear column 21 allows the clamping half ring 22 to open to both sides.
