Description

Technical Field

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

[0002] Rainwater harvesting and reuse systems are widely used in homes, agriculture, industry, and urban management to collect, store, and utilize rainwater. They not only save water resources but also reduce rainwater runoff and alleviate urban flooding problems.

[0003] Currently, in order to conserve water resources and reduce reliance on tap water for greening irrigation, landscape water replenishment, and road cleaning, rainwater harvesting equipment is generally installed on hard surfaces (such as squares and roads) in landscape parks. Rainwater from hard surfaces collects and flows into the rainwater harvesting equipment. However, due to the abundance of flowers, trees, soil, and gravel in parks, fallen leaves, gravel, or other garbage may enter the rainwater collection tank through the rainwater collection inlet over time, causing the rainwater collected in the tank to be easily contaminated, thus affecting the normal collection of rainwater. To prevent leaves, gravel, or garbage from entering the rainwater collection tank and contaminating the collected rainwater, a grille or filter is generally installed inside the rainwater collection inlet to intercept fallen leaves, gravel, or garbage, thus preventing them from entering the rainwater collection tank.

[0004] However, after prolonged use, rainwater harvesting devices accumulate a large amount of leaves, gravel, or garbage on top of the grille or filter, causing blockages that prevent rainwater from flowing through the collection inlet into the rainwater collection tank. This affects the normal collection of rainwater. Before the rainy season, the blockages on top of the grille or filter are often removed manually or with tools, which requires a lot of time and effort and reduces the efficiency of cleaning the blockages. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rainwater harvesting and reuse device, which aims to improve the problems in the prior art.

[0008] The filter screen is fixedly installed inside the collection box;

[0009] The backing plate is fixedly connected to the top of the storage box at one end. An anti-clogging component is fixedly installed on one side of the backing plate to prevent the filter screen from clogging. A negative pressure chamber can be formed inside the anti-clogging component. The negative pressure chamber can clean the leaves, gravel and garbage accumulated on the top of the filter screen and provide a flow channel for rainwater collection.

[0010] As a further description of the above technical solution:

[0011] The anti-clogging component includes a mounting box and a collecting roller. The mounting box is slidably installed in the inner cavity of the collecting box and is located directly above the filter screen. The collecting roller is rotated and installed in the inner cavity of the mounting box via a rotating shaft. Multiple rows of cleaning bristles for cleaning the top of the filter screen are fixedly installed on the outer wall of the collecting roller along its own axis. A drive motor for rotating the collecting roller is fixedly installed in the inner cavity of the mounting box.

[0012] As a further description of the above technical solution:

[0013] The top of the installation box is fixedly installed with a connecting hose that communicates with its own inner cavity.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-5 One embodiment of this utility model is a rainwater harvesting and reuse device, comprising:

[0032] The storage tank 1 for storing rainwater has a collection tank 9 for collecting rainwater fixedly installed on one side of its top. When using the storage tank 1 to collect rainwater, the storage tank 1 is first buried underground, while the collection tank 9 extends above the ground. When the rainy season arrives, rainwater on the ground and rainwater falling from the ground enter the inner cavity of the storage tank 1 through the water inlet of the collection tank 9, thus providing a flow channel for rainwater to enter the inner cavity of the storage tank 1, thereby realizing the collection of rainwater (this is existing technology and will not be described in detail here).

[0033] The filter screen 10 is fixedly installed in the inner cavity of the collection box 9. When leaves, gravel, or garbage enter the inner cavity of the collection box 9 with the airflow, the filter screen 10 can trap the leaves, gravel, or garbage at its top, preventing them from entering the inner cavity of the storage box 1 through the collection box 9 and causing continuous pollution of the rainwater in the storage box 1. It can also prevent leaves, gravel, or garbage from accumulating in the inner cavity of the storage box 1 and reducing the amount of rainwater collected by the storage box 1.

[0034] The anti-clogging component includes a mounting box 3 and a collecting roller 12. The mounting box 3 is slidably installed in the inner cavity of the collecting box 9 and is located directly above the filter screen 10. The collecting roller 12 is rotatably installed in the inner cavity of the mounting box 3 via a rotating shaft. Multiple rows of cleaning bristles for cleaning the top of the filter screen 10 are fixedly installed on the outer wall of the collecting roller 12 along its own axis. A drive motor for rotating the collecting roller 12 is fixedly installed in the inner cavity of the mounting box 3. The power output end of the drive motor is fixedly connected to one end of one of the rotating shafts away from the collecting roller 12. When removing leaves, gravel, or garbage accumulated on the top of the filter screen 10, the mounting box 3 is moved along the top of the filter screen 10, and the drive motor is started to rotate the collecting roller 12. The cleaning bristles rotate with the collecting roller 12. The rotating cleaning bristles continuously beat the top of the filter screen 10, applying a pushing force away from the mounting box 3 to the garbage, gravel, or leaves in contact.

[0035] The space between the cleaning brush bristles and the inner wall of the installation box 3 is used for the movement of leaves, gravel, or garbage, thus forming a movement channel for leaves, gravel, or garbage, making it easier for leaves, gravel, or garbage to enter the inner cavity of the installation box 3.

[0036] The cleaning bristles located at the bottom of the collecting roller 12 contact the top of the filter screen 10. As the collecting roller 12 continues to rotate, the cleaning bristles continuously beat the top of the filter screen 10, thereby applying a pushing force to the small gravel, broken leaves, and debris stuck in the holes of the filter screen 10, sweeping them out of the holes and into the inner cavity of the mounting box 3 or dropping them into the inner cavity of the storage box 1 (the gravel that falls into the inner cavity of the storage box 1 is small in size and quantity and will not have a significant impact on the normal collection of rainwater). This prevents a large amount of small gravel, broken leaves, and debris from accumulating in the holes of the filter screen 10, which would affect the rainwater passing through the filter screen 10 and entering the interior of the storage box 1, thus increasing the rate at which rainwater enters the interior of the storage box 1.

[0037] A baffle plate 2 is fixedly installed on one side of the bottom of the mounting box 3 to prevent debris from splashing. The baffle plate 2 is inclined away from the mounting box 3. At the same time, side plates connected to the side walls of the baffle plate 2 are fixedly installed on both sides of the mounting box 3. The bottom of the side plates is parallel to the bottom of the baffle plate 2. Garbage, gravel, or leaves that come into contact with the cleaning brush bristles are pushed between the baffle plate 2 and the two side plates. As the collecting roller 12 continues to rotate, the garbage, gravel, or leaves accumulated between the two side plates and the baffle plate 2 are continuously transferred into the inner cavity of the mounting box 3. The two side plates and the baffle plate 2 can effectively prevent garbage, gravel, or leaves from being rolled into the inner cavity of the mounting box 3 and scattering around the mounting box 3.

[0038] A connecting hose 4, which communicates with the inner cavity of the installation box 3, is fixedly installed on the top. A top plate, which connects to the top of the storage box 1, is fixedly installed on the outer wall of the connecting hose 4. A discharge pipe is fixedly installed at the other end of the connecting hose 4. A negative pressure pump is fixedly installed in the inner cavity of the discharge pipe. When the drive motor is started, the vacuum pump is also started. The vacuum pump creates a negative pressure chamber between the connecting hose 4 and the interior of the installation box 3, thereby quickly sucking the garbage, gravel, or leaves sucked into the inner cavity of the installation box 3 into the inner cavity of the connecting hose 4. The garbage, gravel, or leaves are transported through the connecting hose to the inner cavity of the discharge pipe and then discharged through the connecting hose. This achieves the cleaning of leaves, gravel, or garbage accumulated on the top of the filter screen 10. When the rainy season comes, rainwater can quickly enter the inner cavity of the storage box 1 through the collection box 9, reducing the time and effort required to clean the blockage and improving the efficiency of blockage removal.

[0039] The connecting hose 4 is composed of a corrugated pipe. When the installation box 3 moves away from the discharge pipe, the end of the connecting hose 4 connected to the installation box 3 moves together with the installation box 3, which extends the connecting hose 4 and allows leaves, gravel or garbage to enter the inner cavity of the connecting hose 4 in real time. At the same time, when the installation box 3 moves in the opposite direction, the connecting hose 4 retracts and continues to collect leaves, gravel or garbage.

[0040] A garbage bin or garbage collection pool can be installed directly below the end of the discharge pipe away from the connecting hose 4 to collect the leaves, gravel, or garbage discharged from the discharge pipe. This prevents the discharged leaves, gravel, or garbage from re-entering the inner cavity of the collection box 9 when washed by rain or when the surrounding air velocity is high, thus preventing the filter screen 10 from being blocked by the removed leaves, gravel, or garbage again.

[0041] The collection roller 12, mounting box 3, connecting hose 4 and vacuum pump can form an anti-clogging component for cleaning leaves, gravel or garbage. The anti-clogging component can quickly clean the blockage on the top of the filter screen 10. Before the rainy season, the leaves, gravel or garbage accumulated on the top of the filter screen 10 can be sucked to the outside of the collection box 9, thus achieving rapid cleaning of leaves, gravel or garbage.

[0042] A backing plate 5 is fixedly installed on one side of the top of the storage box 1. The top of the backing plate 5 is located above the collection box 9. A synchronous belt 11 is fixedly and rotatably installed on the side of the backing plate 5 near the collection box 9. A connecting plate 7 is fixedly installed on the top of the installation box 3. The end of the connecting plate 7 away from the synchronous belt 11 is fixedly connected to the bottom of the synchronous belt 11. A drive motor for rotating the synchronous belt 11 is fixedly installed on the side of the backing plate 5 away from the synchronous belt 11. After the drive motor is started, the synchronous belt 11 can be rotated. When the synchronous belt 11 rotates, the connecting plate 7 connected to it rotates together, which can provide power for the movement of the installation box 3, allowing the installation box 3 to move back and forth along the top of the filter screen 10.

[0043] As the mounting box 3 and connecting plate 7 move with the synchronous belt 11, the bottom of the synchronous belt 11 deforms due to its own weight. At the same time, the operation of the dust pump and drive motor causes the mounting box 3 to vibrate. The vibration of the mounting box 3 obstructs the movement of the synchronous belt 11, and the deformation becomes more severe. Over time, the synchronous belt 11 separates from the synchronous roller, which adversely affects the normal movement of the mounting box 3.

[0044] To solve the above technical problems, a guide rail 13 is fixedly installed on the side of the back plate 5 near the collection box 9. A support plate 8 is slidably installed in the inner cavity of the guide rail 13. One end of the support plate 8 is fixedly connected to the top of the mounting box 3. When the mounting box 3 moves with the synchronous belt 11, the support plate 8 moves with the mounting box 3. At the same time, the other end of the support plate 8 moves along the guide rail 13, thereby limiting the movement trajectory of the mounting box 3 and supporting the mounting box 3, preventing the mounting box 3 from shaking significantly and improving the stability of the movement of the mounting box 3.

[0045] A protective cover 6 for protecting the synchronous belt 11 is fixedly installed on one side of the back plate 5. The protective cover 6 can protect the synchronous belt 11, prevent the synchronous belt 11 from being exposed for a long time and causing serious aging, and extend the service life of the synchronous belt 11.

[0046] The bottom of the protective cover 6 and the side near the mounting box 3 are provided with sliding grooves for the movement of the connecting plate 7 and the support plate 8. The sliding grooves on the bottom and side walls can limit the movement trajectory of the connecting plate 7 and the support plate 8, protecting the synchronous belt 11 without hindering the movement of the connecting plate 7 and the support plate 8.

[0047] It should be noted that if the gravel on the filter screen 10 is relatively large, the suction provided by the dust pump may not be able to suck up the gravel. However, when the collecting roller 12 and the baffle plate 2 move horizontally, they will push the large gravel particles to one side of the filter screen 10 for manual collection and processing.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
