Description
Technical Field
[0001] This application relates to the field of water resource recycling and reuse technology in building construction projects, specifically a rainwater collection device for building construction. Background Technology
[0002] In the process of modern urban construction, with the increasing environmental awareness and technological advancements, the concept of "sponge city" has gradually gained popularity. To achieve this goal, the construction industry has begun to emphasize the effective management and rational utilization of natural rainfall, especially roof runoff—the so-called "green roof"—using rainwater harvesting devices to collect and reuse rainwater from rooftops. However, many existing stormwater management systems on the market, while capable of initial filtration, often lack effective long-term maintenance mechanisms, leading to high subsequent operating costs and susceptibility to clogging, damage, or even failure.
[0003] Although existing rainwater harvesting devices are equipped with filter plates to filter rainwater collected from the roof, after a long period of use, a large amount of filtered debris will accumulate on the filter plates, affecting the normal water flow rate of the filter plates and causing rainwater to overflow from the filter plates, thus affecting the rainwater harvesting effect. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a rainwater harvesting device for building construction. This device has the advantages of cleaning debris adhering to a filter plate, ensuring unobstructed water flow through the filter plate's holes, preventing debris accumulation from affecting the normal water flow rate, and preventing rainwater overflow. This improves the rainwater harvesting effect and solves the problem that while existing rainwater harvesting devices have filter plates to filter rainwater collected from the roof, a large amount of filtered debris accumulates on the filter plate after prolonged use, affecting the normal water flow rate and causing rainwater overflow, thus impacting the rainwater harvesting effect.
[0005] To achieve the above-mentioned goal of cleaning debris attached to the filter plate, ensuring unobstructed water passage holes on the filter plate, preventing debris accumulation from affecting the normal water passage speed of the water passage holes, preventing rainwater overflow, and improving the rainwater collection effect, this application provides the following technical solution: A rainwater collection device for building construction includes a collection box, a filter plate is installed inside the collection box, rotating rollers are rotatably installed on both sides of the inner wall of the collection box via two rotating shafts, a connecting plate is installed on the outer surface of the middle part of the rotating rollers, a cleaning brush is installed at the end of the connecting plate away from the rotating rollers, the middle part of the filter plate is arc-shaped, the arc-shaped plate in the middle of the filter plate is concentric with the rotating rollers, the outer surface of the middle part of one side of the filter plate is slidably connected to the outer surface of one side of the cleaning brush, a water pipe is installed above the filter plate, the outlet of the water pipe is located on the left side above the rotating rollers, and the outlet of the water pipe is located above the connecting plate.
[0006] The above solution utilizes rainwater from natural rainfall and water pipes to fall onto the connecting plate, pushing the plate and causing it to rotate via a rotating roller. This rotation drives a cleaning brush to scrape against the filter plate, removing debris from one side of the filter plate's outer surface. This effectively removes debris from the filter plate, ensuring unobstructed water flow through the filter holes, preventing debris accumulation from affecting the normal water flow rate, and preventing rainwater overflow. This improves the efficiency of rainwater collection.
[0007] Furthermore, a water inlet is provided in the middle of the connecting plate, and a gravity water collection bucket is provided on one side of the connecting plate, with the gravity water collection bucket located at the water inlet of the connecting plate.
[0008] The above scheme allows rainwater to be collected by a gravity water collection bucket. The collected rainwater then powers the connecting plate, causing it to rotate stably. This allows the connecting plate to reliably drive the cleaning brush to clean the filter plate.
[0009] Furthermore, a protective shell is provided on the top of the collection box, and one edge of the protective shell is located on the left side of the rotating roller.
[0010] The above solution prevents rainwater from washing onto the back of the connecting plate and the gravity water collection hopper by setting up a protective shell. This allows rainwater to drive the connecting plate through only one side of the connecting plate and the gravity water collection hopper, enabling the connecting plate to rotate counterclockwise stably via the rotating roller.
[0011] Furthermore, the outer surface of the middle part of the water pipe is fixedly installed inside the inner wall of one end of the support frame, the support frame is installed on the top of the protective shell, and one end of the water pipe is connected to a pipe connection assembly.
[0012] The above solution allows the water pipe to be fixed in place by setting up a support frame. The pipe connection component at one end of the water pipe can be connected to an external drainage pipe, which can be easily connected to the roof drainage pipe. In this way, rainwater can be collected from the roof by using the water pipe in conjunction with the roof drainage pipe.
[0013] Furthermore, the inside of the collection box is provided with a debris collection box, one side of which is connected to one end of the filter plate, and the debris collection box has a drainage hole on the side near the filter plate.
[0014] The above solution allows for the collection of debris cleaned by the cleaning brush on the filter plate through a debris collection box inside the collection box. This allows the cleaning brush to directly scrape the debris from the filter plate into the debris collection box. A drainage hole on one side of the debris collection box allows rainwater to be discharged into the collection box.
[0015] Furthermore, a measuring plate is slidably disposed inside the debris collection box, and a connecting rod is disposed on the top of the measuring plate. The connecting rod extends to the top of the protective shell, and the outer surface of one end of the connecting rod is slidably connected to the inner wall of the top of the protective shell. A fixing plate is disposed at the end of the connecting rod away from the measuring plate, and a spring is disposed at the bottom of the fixing plate. The end of the spring away from the fixing plate is disposed at the top of the protective shell.
[0016] With the above method, when debris enters the debris collection box, it will fall onto the measuring plate. The increasing weight of the debris on the measuring plate will gradually overcome the spring force, causing the measuring plate to move downwards as the debris accumulates. This, in turn, will cause the connecting rod to move downwards. The amount of debris collected in the debris collection box can be determined by the distance the connecting rod moves above the protective shell, thus determining whether the debris in the debris collection box needs to be cleaned.
[0017] Furthermore, a cleaning port is provided on one side of the collection box, and a box door is hinged to one side of the collection box, with the box door located at the cleaning port on one side of the collection box.
[0018] With the above solution, the debris inside the collection box can be easily cleaned by opening the door at the cleaning port on one side of the collection box.
[0019] Furthermore, the number of connecting plates is three, and the three connecting plates are arranged in a uniform ring array on the outer surface of the middle part of the rotating roller.
[0020] The above scheme allows the three connecting plates to move continuously and alternately with the rainwater, thereby continuously cleaning the debris on the filter plates and ensuring that the filter plates can stably perform filtration and drainage work.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This rainwater harvesting device for building construction utilizes rainwater from natural rainfall and water pipes. The rainwater falls onto a connecting plate, pushing the plate and causing it to rotate via a rotating roller. This rotates the roller, causing a cleaning brush to scrape against a filter plate, removing debris from one side of the filter plate's outer surface. This effectively removes debris from the filter plate, ensuring unobstructed water flow through the filter holes, preventing debris accumulation from affecting the normal water flow rate, and preventing rainwater overflow. This significantly improves the rainwater harvesting efficiency. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 3 and Figure 4This embodiment of a rainwater collection device for building construction includes a collection box 1, a filter plate 2 inside the collection box 1, and rotating rollers 3 rotatably mounted on both sides of the inner wall of the collection box 1 via two rotating shafts. A connecting plate 4 is mounted on the outer surface of the middle part of the rotating roller 3, and a cleaning brush 5 is mounted on the end of the connecting plate 4 away from the rotating roller 3. The middle part of the filter plate 2 is arc-shaped, and the arc-shaped plate in the middle part of the filter plate 2 is concentric with the rotating roller 3. The outer surface of the middle part of one side of the filter plate 2 is slidably connected to the outer surface of the cleaning brush 5 on one side. Through the arc-shaped design of the middle part of the filter plate 2, the cleaning brush 5 can completely clean the arc-shaped outer surface of the middle part of one side of the filter plate 2 when it moves. A water pipe 9 is mounted above the filter plate 2. The outlet of the water pipe 9 is located on the left side above the rotating roller 3, and the outlet of the water pipe 9 is located above the connecting plate 4.
[0033] Please see Figure 3 , Figure 4 and Figure 6 A water inlet is provided in the middle of the connecting plate 4, and a gravity water collection bucket 6 is provided on one side of the connecting plate 4. The gravity water collection bucket 6 is located at the water inlet of the connecting plate 4. The gravity water collection bucket 6 can collect rainwater, and then the gravity water collection bucket 6 can apply power to the connecting plate 4 through the collected rainwater, causing the connecting plate 4 to rotate stably, so that the connecting plate 4 can stably drive the cleaning brush 5 to clean the filter plate 2.
[0034] Please see Figure 1 , Figure 2 and Figure 4 The top of the collection box 1 is provided with a protective shell 7. One edge of the protective shell 7 is located on the left side of the rotating roller 3. The protective shell 7 prevents rainwater from washing onto the back of the connecting plate 4 and the gravity water collection hopper 6, so that rainwater can only drive the connecting plate 4 through the one side of the connecting plate 4 and the gravity water collection hopper 6, so that the connecting plate 4 can be stably rotated counterclockwise by the rotating roller 3.
[0035] Please see Figure 1 , Figure 2 and Figure 4 The outer surface of the middle part of the water pipe 9 is fixedly installed inside the inner wall of one end of the support frame 8. The support frame 8 is set on the top of the protective shell 7. One end of the water pipe 9 is connected to a pipe connection component 16. The position of the water pipe 9 can be fixed by the support frame 8. The pipe connection component 16 at one end of the water pipe 9 can be connected to an external drain pipe, which can be easily connected to the roof drain pipe. Then, the rainwater on the roof can be collected by the water pipe 9 in conjunction with the roof drain pipe.
[0036] Please see Figure 3 and Figure 4The collection box 1 is equipped with a debris collection box 10 inside. One side of the debris collection box 10 is connected to one end of the filter plate 2. The debris collection box 10 has a drainage hole on the side near the filter plate 2. The debris collected by the cleaning brush 5 on the filter plate 2 can be collected through the debris collection box 10 inside the collection box 1. The cleaning brush 5 can directly scrape the debris on the filter plate 2 into the debris collection box 10. The drainage hole on one side of the debris collection box 10 can discharge the rainwater in the debris collection box 10 into the collection box 1.
[0037] Please see Figure 3 , Figure 4 and Figure 5 A measuring plate 11 is slidably installed inside the debris collection box 10. A connecting rod 12 is installed on the top of the measuring plate 11 and extends to the top of the protective shell 7. The outer surface of one end of the connecting rod 12 is slidably connected to the inner wall of the top of the protective shell 7. A fixing plate 13 is installed at the end of the connecting rod 12 away from the measuring plate 11. A spring 14 is installed at the bottom of the fixing plate 13. The end of the spring 14 away from the fixing plate 13 is installed at the top of the protective shell 7. When debris enters the debris collection box 10, it will fall onto the measuring plate 11. The increasing weight of the debris on the measuring plate 11 will gradually overcome the elastic force of the spring 14, causing the measuring plate 11 to move downwards gradually due to the increasing amount of debris above. This, in turn, will drive the connecting rod 12 to move downwards gradually. The amount of debris collected in the debris collection box 10 can be determined by the movement distance of the connecting rod 12 above the protective shell 7, and thus it can be determined whether the debris in the debris collection box 10 needs to be cleaned.
[0038] Please see Figure 1 , Figure 3 and Figure 4 A cleaning opening is provided on one side of the collection box 1. A door 15 is hinged to one side of the collection box 1. The door 15 is located at the cleaning opening on one side of the collection box 1. By opening the door 15 at the cleaning opening on one side of the collection box 1, the debris in the debris collection box 10 can be easily cleaned.
[0039] Please see Figure 3 , Figure 4 and Figure 6 There are three connecting plates 4, which are arranged in a uniform ring array on the outer surface of the middle part of the rotating roller 3. Through the cooperation of the three connecting plates 4, the three connecting plates 4 can move continuously and alternately through rainwater, thereby continuously cleaning the debris on the filter plate 2 and ensuring that the filter plate 2 can stably perform filtration and water diversion work.
[0040] In this embodiment, a rainwater collection device for building construction utilizes rainwater from natural rainfall and water discharged through pipe 9 to fall onto a connecting plate 4. This pushes the connecting plate 4, causing it to rotate via a rotating roller 3. This, in turn, drives a cleaning brush 5 to scrape across a filter plate 2, cleaning debris adhering to one side of the outer surface of the filter plate 2. This effectively removes debris from the filter plate 2, ensuring the unobstructed flow of water through the filter plate 2's holes. It prevents debris accumulation from affecting the normal flow rate of the water through the holes, thus preventing rainwater overflow and improving the rainwater collection efficiency.
[0041] The working principle of the above embodiment is as follows: the pipe connection assembly 16 at one end of the water pipe 9 is connected to the roof drain pipe. The rainwater collected by the roof drain pipe is discharged onto the filter plate 2 through the water pipe 9. The impurities in the rainwater are filtered by the filter plate 2. At the same time, the rainwater discharged from the water pipe 9 and the rainwater from natural rainfall fall onto the connecting plate 4, and the rainwater enters the gravity collection bucket 6. The gravity collection bucket 6, together with the gravity of the rainwater and the gravity of the rainwater falling on the connecting plate 4, drives the connecting plate 4 to move counterclockwise, causing the rotating roller 3 to rotate counterclockwise. When the connecting plate 4 rotates counterclockwise, it drives the cleaning brush 5 to brush and clean the surface of the filter plate 2. The brushing of the cleaning brush 5 washes the impurities attached to the filter plate 2 into the impurity collection box 10. The three connecting plates 4 cooperate with each other and alternate continuously. The corresponding cleaning brush 5 cleans the filter plate 2. When debris enters the debris collection box 10, it falls on the top of the measuring plate 11. The weight of the debris overcomes the elastic force of the spring 14, causing the measuring plate 11 to move downward in the debris collection box 10 to a distance that matches the weight of the debris. This causes the measuring plate 11 to move the connecting rod 12 downward, and the connecting rod 12 to gradually squeeze the spring 14 through the fixing plate 13. The amount of debris collected in the debris collection box 10 can be determined by the movement distance of the connecting rod 12 above the protective shell 7. This allows it to be determined whether the debris in the debris collection box 10 needs to be cleaned. When it is necessary to clean the debris in the debris collection box 10, the box door 15 is opened, and the debris in the debris collection box 10 is cleaned through the cleaning port on one side of the collection box 1.
