Description

Technical Field

[0001] This application belongs to the field of rainwater harvesting technology, specifically relating to a wall-mounted rainwater harvesting device. Background Technology

[0002] Rainwater harvesting systems are devices used to collect and store natural precipitation, typically consisting of collection, filtration, and storage components. By utilizing rainwater resources, these systems can effectively reduce dependence on traditional water sources, lower water costs, and promote the sustainable use of water resources. They have broad application prospects in areas such as homes, agriculture, and urban greening, contributing to the achievement of energy conservation and environmental protection goals.

[0003] In existing technologies, some rainwater harvesting devices employ a wall-mounted design to save floor space and facilitate installation on building exteriors or other vertical surfaces. These devices are typically fixed to the wall via brackets, bolts, or suspension structures, with the water collection components exposed to the environment to collect rainwater and guide it into a storage container.

[0004] The inventors discovered that because the rainwater harvesting device is wall-mounted externally, it is difficult for people to directly clean the impurities (such as leaves and debris) that accumulate on its surface. In cases of heavy leaf fall and heavy rainfall, these impurities can easily clog the water collection channels or filter components, leading to a decrease in rainwater collection efficiency and even damage to the device or waste of water resources. Summary of the Invention

[0005] This application provides a wall-mounted rainwater harvesting device designed to automatically clean impurities from its surface, thereby ensuring rainwater harvesting efficiency and preventing device damage and water waste.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A wall-mounted rainwater harvesting device is provided, comprising: The water storage tank has a hollow interior and an open top structure, and is used to fix it to the exterior wall of the building. The bottom of the water storage tank is connected to a water outlet pipe, which is connected to a water outlet valve and is used to connect to a rainwater purification module or an indoor water module. A reserved hole is also provided on the outer wall of the water storage tank. The water collection tank has a hollow interior and an open exterior, and its open area is larger than that of the water storage tank. The water collection tank is hinged to the outside of the water storage tank, and its inner side is provided with a primary filter hole. When the water collection tank swings to the point where its open side faces upward, the primary filter hole communicates with the open side of the water storage tank. A sliding member is slidably disposed on the outside of the water collection tank along the axial direction of the reserved hole, and a partition is hinged to the sliding member; when the partition swings to a horizontal state, the sliding member can slide until the partition inserts into and fills the reserved hole; furthermore, the partition has secondary filter holes, the diameter of which is smaller than that of the primary filter holes; and The discharge pipe is used to be fixed on the outer wall of the building. Its top is connected to the sliding member through the material collection component, and the material collection component has a material collection cavity that communicates with the discharge pipe and is open to the upward side. The water collection tank can swing so that its open surface is tilted, allowing impurities inside to fall out; the sliding member can drive the partition to move outside the water storage tank, and the partition can swing to an inclined state outside the water storage tank, allowing impurities on its upper side to fall into the collection cavity; and the water collection tank and the partition in the inclined state are aligned to form an inclined surface for guiding impurities.

[0007] In one possible implementation, the inner wall of the water tank has a U-shaped boss, the boss is aligned with the reserved hole on the horizontal plane, and the outer periphery of the partition is fitted with a sealing strip suitable for filling the gap between the boss and the partition.

[0008] In one possible implementation, the boss has a slot on the side facing the reserved hole, and the swing end face of the partition has a mating post suitable for insertion into the slot.

[0009] In one possible implementation, a sinking groove is provided on the outer side of the water collection tank, and the sinking groove extends through the open surface of the water collection tank, so that when the water collection tank and the partition are aligned, the docking post is embedded in the sinking groove.

[0010] In one possible implementation, the aggregate component includes: A material collecting plate is disposed on the lower side of the sliding member and is fixedly connected to the sliding member; the material collecting plate has a material passage extending in the vertical direction; and The feed pipe is made of flexible material and is fixedly installed on the lower side of the collecting plate. Its upper end is connected to the feed port and its lower end is connected to the discharge pipe to form the collecting cavity. The feed tube has a structure in which the inner diameter gradually decreases from top to bottom.

[0011] In one possible implementation, the partition has a through-hole along the thickness direction, and a filter screen is embedded in the through-hole; The filter screen has mesh openings that form the secondary filtration holes; the thickness of the filter screen is less than the thickness of the partition plate, so that a groove structure for accommodating impurities is formed between the surfaces of the filter screen and the partition plate.

[0012] In one possible implementation, a linear cylinder is fixedly installed on the outside of the water tank, and the power output end of the linear cylinder is connected to the sliding member in a transmission manner. The water storage tank is also equipped with a sealed protective cover that covers the outside of the linear cylinder to prevent rainwater from entering the interior of the linear cylinder.

[0013] In one possible implementation, the water collection tank has an outwardly extending connecting plate that is hinged to the water storage tank, and a driven gear is fixedly connected to its hinge shaft. The upper rotating motor is fixedly installed on the outside of the water storage tank; the power output axis of the upper rotating motor is parallel to the hinge axis of the connecting plate, and the power output end of the upper rotating motor is connected to a driving gear that meshes with the driven gear.

[0014] In one possible implementation, the partition has an outwardly extending convex shaft, the slider has a receiving cavity suitable for inserting the convex shaft, and a downward rotating motor connected to the convex shaft is fixedly disposed in the receiving cavity.

[0015] In one possible implementation, a grille is embedded in the opening of the water tank; When the water collection tank swings to its open side facing upwards, the primary filter holes communicate with the grid holes on the grille.

[0016] In this embodiment, the coordinated design of the water collection tank, sliding component, baffle, and discharge pipe achieves the collection, guidance, and automatic discharge of impurities. Specifically, the water collection tank can swing to an inclined state to empty large particles (such as fallen leaves) accumulated inside. Simultaneously, the sliding component can drive the baffle to slide out of the water tank and swing to an inclined state. This not only allows fine impurities intercepted on its surface to slide off under gravity, but more importantly, the inclined water collection tank and the inclined baffle are aligned at this time, forming a continuous guiding inclined surface. This guiding inclined surface smoothly guides the impurities poured out of the water collection tank into the collection cavity of the collecting component, and finally all impurities are discharged uniformly through the discharge pipe. This series of actions achieves automated cleaning of impurities in the core filtration area of ​​the device, effectively solving the clogging problem caused by impurity accumulation.

[0017] The wall-mounted rainwater harvesting device provided in this embodiment has the following significant advantages compared with the prior art: Firstly, the combination of a swingable water collection tank and a sliding, swingable baffle enables automated and centralized cleaning of impurities from the primary and secondary filters, eliminating the need for personnel to climb high for dangerous and tedious manual cleaning, thus greatly improving the safety and convenience of maintenance operations.

[0018] Secondly, by establishing a continuous impurity-guiding inclined surface, it is ensured that impurities can be efficiently and reliably recovered and discharged during the cleaning process, fundamentally avoiding the problem of reduced rainwater collection efficiency caused by debris such as fallen leaves clogging the filter holes, and ensuring the stable operation of the device under severe weather conditions.

[0019] Thirdly, while achieving automatic cleaning, all moving parts of the device are based on simple hinge and sliding structures, resulting in a compact structure, simple drive method, and low manufacturing and maintenance costs. This effectively overcomes the market penetration bottleneck of existing wall-mounted devices, which are prone to clogging and difficult to maintain, and enhances the product's practicality and market competitiveness.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] Please refer to the following: Figures 1 to 12 The wall-mounted rainwater harvesting device provided in this application will now be described. The wall-mounted rainwater harvesting device proposed in this application includes a water storage tank 1, a water collection tank 2, a sliding component 3, and a discharge pipe 4.

[0027] The water storage tank 1 has a hollow interior and an open top; the water storage tank 1 is used to fix to the exterior wall of the building, specifically by supporting the water storage tank 1 with brackets pre-fixed to the wall.

[0028] The bottom of the water storage tank 1 is connected to a water outlet pipe 11, and a water outlet valve 12 is connected to the water outlet pipe 11 to control whether the water outlet is open or closed. In actual use, the water outlet pipe 11 is used to connect to the rainwater purification module or the indoor water module, and the discharge of liquid in the water storage tank 1 is regulated by controlling the state of the water outlet valve 12.

[0029] Meanwhile, a reserved hole 13 communicating with the interior is also provided on the outer wall of the water storage tank 1. In this embodiment, for ease of description, the axial direction of the reserved hole 13 is defined as the front-to-back direction; correspondingly, the length direction of the reserved hole 13 on the horizontal plane is defined as the left-to-right direction. Based on this, the inner wall of the reserved hole 13 facing the left-to-right direction is aligned with the inner wall of the water storage tank 1 facing the left-to-right direction, so that the structure inserted into the reserved hole 13 can cooperate with the inner wall of the water storage tank 1 to achieve vertical separation of the internal space of the water storage tank 1.

[0030] The water collection tank 2 has a hollow interior and an open exterior, with an open area larger than that of the water storage tank 1. This allows the water collection tank 2 to swing to an upward-facing position, increasing the water inflow area for the water storage tank 1 and ensuring efficient rainwater collection per unit time. Specifically, the water collection tank 2 is hinged to the outside of the water storage tank 1, and a primary filter hole 21 is provided on its inner side (the side opposite the open side). When the water collection tank 2 swings to an upward-facing position, the primary filter hole 21 connects with the open side of the water storage tank 1, enabling directional discharge of collected rainwater and preliminary filtration of impurities.

[0031] The sliding member 3 is slidably disposed on the outer side of the water collection tank 2 facing the left and right directions along the axial direction (i.e., the front-back direction) of the reserved hole 13; in this embodiment, there are two sliding members 3, and the two sliding members 3 are respectively disposed on the left and right sides of the water collection tank 2.

[0032] A partition 5 is hinged to the sliding member 3; in this embodiment, there is a single partition 5, and the left and right sides of the partition 5 are respectively hinged to two sliding members 3. Based on this, when the partition 5 swings to a horizontal state, the sliding member 3 can slide to allow the partition 5 to be inserted into and fill the reserved hole 13.

[0033] The partition 5 is provided with a secondary filter hole. The diameter of the secondary filter hole is smaller than that of the primary filter hole 21, so as to achieve secondary filtration of impurities and ensure that there are no impurities in the liquid entering the outlet pipe 11.

[0034] The discharge pipe 4 is used to fix it to the outer wall of the building; the top of the discharge pipe 4 is connected to the sliding member 3 through the collecting member 6; the collecting member 6 is provided with an upward-opening collecting cavity, which is connected to the discharge pipe 4.

[0035] The water collection tank 2 can be tilted so that the open side is tilted, allowing the impurities accumulated inside to slide out.

[0036] The sliding member 3 can move the partition 5 to the outside of the water storage tank 1; the partition 5 can swing to an inclined state outside the water storage tank 1, so that impurities on its surface fall into the collection cavity.

[0037] Furthermore, the inclined water collection tank 2 and the partition 5 are aligned and parallel to each other, together forming a continuous inclined surface that guides impurities.

[0038] This design enables automatic guidance and collection of impurities. During the cleaning process, impurities slide down the inclined surface of the water collection tank 2 to the surface of the baffle 5, and then are guided into the material collection channel through the baffle 5. Finally, they are discharged through the discharge pipe 4, effectively preventing the inconvenience and safety risks of manual cleaning.

[0039] In this embodiment, the coordinated design of the water collection tank 2, the sliding member 3, the partition 5 and the discharge pipe 4 enables the collection, guidance and automatic discharge of impurities.

[0040] Specifically, the water collection tank 2 can swing to an inclined state to empty large particles (such as fallen leaves) accumulated inside. Simultaneously (when there is no residue inside the water storage tank 1 or the water level is below the pre-drilled hole 13), the sliding member 3 can drive the partition 5 to slide out of the water storage tank 1 and swing to an inclined state. This not only allows the fine impurities intercepted on its surface to slide off under gravity, but more importantly, at this time, the inclined water collection tank 2 and the inclined partition 5 are aligned, forming a continuous guiding inclined surface. This guiding inclined surface can smoothly guide the impurities poured out from the water collection tank 2 into the collection cavity of the collection component 6, and finally all impurities are discharged uniformly through the discharge pipe 4. This series of actions achieves automated cleaning of impurities in the core filtration area of ​​the device, effectively solving the clogging problem caused by impurity accumulation.

[0041] The wall-mounted rainwater harvesting device provided in this embodiment has the following significant advantages compared with the prior art: Firstly, by combining the swingable water collection tank 2 and the sliding and swingable baffle 5, the system achieves automated and centralized cleaning of impurities from the primary and secondary filters, eliminating the need for personnel to climb high for dangerous and tedious manual cleaning, thus greatly improving the safety and convenience of maintenance operations.

[0042] Secondly, by establishing a continuous impurity-guiding inclined surface, it is ensured that impurities can be efficiently and reliably recovered and discharged during the cleaning process, fundamentally avoiding the problem of reduced rainwater collection efficiency caused by debris such as fallen leaves clogging the filter holes, and ensuring the stable operation of the device under severe weather conditions.

[0043] Thirdly, while achieving automatic cleaning, all moving parts of the device are based on simple hinge and sliding structures, resulting in a compact structure, simple drive method, and low manufacturing and maintenance costs. This effectively overcomes the market penetration bottleneck of existing wall-mounted devices, which are prone to clogging and difficult to maintain, and enhances the product's practicality and market competitiveness.

[0044] In some embodiments, such as Figure 4 and Figure 10 As shown, the inner wall of the water storage tank 1 is provided with a door-shaped protrusion 14, which is aligned with the reserved hole 13 on the horizontal plane; specifically, the upper and lower sides of the protrusion 14 are aligned with the inner top surface and inner bottom surface of the reserved hole 13, respectively, and the inner walls of the protrusion 14 facing left and right are aligned with the inner walls of the reserved hole 13 facing left and right.

[0045] Based on the foregoing, a sealing strip 51 is fitted around the outer periphery of the partition 5. After the partition 5 is inserted into the reserved hole 13, the sealing strip 51 is used to fill the gap between the boss 14 and the partition 5.

[0046] This structure improves the sealing between the partition 5 and the water storage tank 1, preventing unfiltered rainwater from directly entering the water storage tank 1 and ensuring the cleanliness of the collected rainwater.

[0047] In some embodiments, such as Figure 4 and Figure 10 As shown, the boss 14 has a slot 141 on the side facing the reserved hole 13; the swing end face of the partition 5 has a docking post 52, which is suitable for insertion into the slot 141.

[0048] The docking column 52 plays a positioning and reinforcement role when the partition 5 is closed, enhancing the stability of the partition 5 in the filtration state and preventing displacement caused by water flow impact.

[0049] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 and Figure 10 As shown, a sinking groove 22 is provided on the outer side of the water collection tank 2; the sinking groove 22 passes through the open surface of the water collection tank 2; when the water collection tank 2 is aligned with the partition 5, the connecting post 52 is embedded in the sinking groove 22.

[0050] The design enables the water collection tank 2 and the baffle 5 to be smoothly connected in the cleaned state, forming a continuous guide surface, preventing impurities from being stuck at the joint, and ensuring that impurities slide smoothly into the collection cavity.

[0051] In some embodiments, such as Figure 1 , Figure 2 and Figure 9 As shown, the material collection component 6 includes a material collection plate 61 and a material passage pipe 62.

[0052] The collecting plate 61 is located on the lower side of the sliding member 3 and is fixedly connected to the sliding member 3; the collecting plate 61 has a material passage 611 that runs through the vertical direction.

[0053] The feed pipe 62 is made of flexible material and is fixedly installed on the lower side of the collecting plate 61. The upper end of the feed pipe 62 is connected to the feed port 611 and the lower end is connected to the discharge pipe 4, together forming a collecting cavity. The feed pipe 62 adopts a structure in which the inner diameter gradually decreases from top to bottom.

[0054] The tapered structure accelerates the fall of impurities and prevents blockages at bends or joints; the flexible feed tube 62 can adapt to positional changes caused by the movement of the sliding member 3, keeping the channel unobstructed.

[0055] In some embodiments, such as Figure 10 and Figure 11 As shown, the partition 5 has a through mounting hole 53 extending along the thickness direction; a filter screen 54 is embedded in the mounting hole 53.

[0056] The mesh of filter screen 54 forms a secondary filtration pore; the thickness of filter screen 54 is less than the thickness of partition plate 5, so that a groove structure for accommodating impurities is formed between the surface of filter screen 54 and partition plate 5.

[0057] The tank structure can temporarily retain the intercepted fine impurities, preventing them from immediately clogging the filter screen 54. During cleaning, these impurities move to the outside of the water tank 1 as the baffle 5 moves horizontally, and slide out as the baffle 5 tilts, improving the self-cleaning effect.

[0058] In some embodiments, such as Figure 8 As shown, a linear cylinder 7 is fixedly installed on the outside of the water storage tank 1. The power output axis of the linear cylinder 7 is parallel to the front and rear direction, and the power output end of the linear cylinder 7 is connected to the sliding member 3 for transmission.

[0059] Based on the foregoing, a sealing protective cover 71 is also provided on the outside of the water storage tank 1. The sealing protective cover 71 is placed on the outside of the linear cylinder 7 to prevent rainwater from entering the interior of the linear cylinder 7.

[0060] The sealed protective cover 71 ensures the long-term reliable operation of the linear cylinder 7 in a humid outdoor environment, preventing the linear cylinder 7 from jamming or being damaged due to rainwater erosion.

[0061] In some embodiments, such as Figures 5 to 7 As shown, the water collection tank 2 is provided with an outwardly extending connecting plate 23; the connecting plate 23 is hinged to the water storage tank 1, and a driven gear 24 is fixedly connected to its hinge shaft.

[0062] An upper rotating motor 8 is fixedly installed on the outside of the water storage tank 1; the power output axis of the upper rotating motor 8 is parallel to the hinge axis of the connecting plate 23; the power output end of the upper rotating motor 8 is connected to a drive gear 81, which meshes with the driven gear 24.

[0063] The gear transmission structure provides stable torque, ensuring that the water collection tank 2 can reliably swing to the specified angle to complete the alignment with the partition 5 at the material discharge position and complete the dumping of impurities.

[0064] In some embodiments, such as Figure 10 and Figure 12 As shown, the partition 5 has an outwardly extending convex shaft 55; the sliding member 3 has a receiving cavity 31, and the convex shaft 55 is inserted into the receiving cavity 31.

[0065] Based on this, a lower rotating motor 32 is fixedly installed inside the receiving cavity 31, and the power output shaft of the lower rotating motor 32 is coaxially connected to the cam shaft 55.

[0066] This built-in drive structure makes the swing control of the partition 5 more precise, while keeping the external structure clean and avoiding interference or safety hazards caused by exposed moving parts.

[0067] In some embodiments, such as Figure 4 and Figure 7 As shown, a grille 9 is embedded in the opening of the water storage tank 1.

[0068] When the water collection tank 2 swings to the point where the open side faces upward, the primary filter hole 21 connects with the grid hole on the grille 9.

[0069] As primary protection, the grating 9 can intercept large falling objects (such as plastic bags and large tree branches), reducing the burden on subsequent filtration structures and extending the maintenance cycle of the device.

[0070] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
