Description

Technical Field

[0001] The present invention relates to the technical field of roof rainwater collection, and specifically to a roof rainwater collection and utilization structure for green building design. Background Art

[0002] With the acceleration of the urbanization process and the improvement of people's awareness of environmental protection, green buildings have gradually become the development trend in the construction field. Green buildings emphasize maximizing resource conservation (energy conservation, land conservation, water conservation, and material conservation), environmental protection, and pollution reduction throughout the entire life cycle of a building, providing people with healthy, applicable, and efficient usage spaces, and coexisting harmoniously with nature. In green buildings, the rainwater collection and utilization system is an important resource conservation technology. It can effectively collect, store, and utilize rainwater, reduce dependence on the urban water supply system, relieve the urban drainage pressure, and at the same time provide non-drinking water sources such as irrigation and toilet flushing for the building, with significant economic and environmental benefits.

[0003] However, there are still some problems in the actual application of existing roof rainwater collection and utilization systems. On the one hand, rainwater is prone to carrying a large amount of impurities during the collection process, such as leaves, dust, sediment, etc. These impurities will clog the filtering device, reduce the rainwater collection efficiency, and affect the normal operation of the system. On the other hand, most traditional filtering devices require manual cleaning or replacement of the filter screen at regular intervals, which not only increases the maintenance cost and workload, but also, in the case of untimely cleaning, is likely to lead to a decline in the filtering effect, and even allow pollutants to enter the water storage system, affecting the water quality of the rainwater and the subsequent utilization effect. In addition, when the filtering element of the existing system is clogged, it often cannot be self-cleaned in a timely and effective manner, further exacerbating the operation problems of the system and reducing the efficiency and reliability of rainwater collection and utilization.

[0004] Therefore, there is an urgent need for a roof rainwater collection and utilization structure for green building design that can effectively solve the above problems, so as to improve the filtering effect and self-cleaning ability of the rainwater collection system, reduce the maintenance cost, enhance the stability and sustainability of the system, and better meet the requirements of green buildings for the efficient utilization of rainwater resources. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides a roof rainwater collection and utilization structure for green building design.

Through the setting of the driving element, the water storage driving force and the gravity of the filter element itself when the filter element is blocked can be utilized to realize the self-cleaning work of the filter element. Effectively, the blocked water source is used to realize the self-cleaning work of the filter element, which not only improves energy conservation and environmental protection, but also enables the filter element to self-start only when it is completely blocked or the filtration efficiency is lower than the rainwater collection rate, preventing frequent cleaning of the filter element, resulting in loosening between components and service life problems, and preventing the problem that the filter element is not cleaned in time, affecting its rainwater collection and utilization effect.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a rooftop rainwater collection and utilization structure designed for green buildings, which has the following beneficial effects:

[0022] 1. The present invention can filter rainwater entering the treatment box by arranging a filter element inside the treatment box, and treat the filtered filter residue by the filter element's own cleaning method. By setting a driving element, the water storage driving force generated when the filter element is blocked and the gravity of the filter element after water storage can be used to achieve self-cleaning of the filter element, which is effective in blocking the collected water source to achieve self-cleaning of the filter element, which not only improves energy conservation and environmental protection, but also makes the filter element self-start only when it is completely blocked or the filtering efficiency is lower than the rainwater collection rate, thereby preventing the filter element from being frequently cleaned, resulting in looseness between components and service life problems, and preventing the filter element from being untimely cleaned, affecting its rainwater collection and utilization effect.

[0023] 2. In the present invention, the filter plate is rotatably connected to the inside of the processing tank through a rotating shaft, and the bottom of the filter plate is supported by a supporting plate, which not only ensures the normal filtering work of the filter plate, but also facilitates the cleaning of the top of the filter plate by the cleaning block. When the cleaning block moves to the end point, with the continuous downward pressure of the driving plate, the filter plate and the supporting plate can be driven to move downward in a fan shape, so that the filter residue on one side of the collection enters the slag discharge frame, realizing the function of automatically discharging the filter residue. Through the elastic extrusion of the supporting plate by the elastic member, the supporting plate and the filter plate can be automatically reset, preventing the rainwater collected inside the processing tank from being discharged through the slag discharge frame and affecting the rainwater collection effect.

[0024] 3. When the filter plate is blocked in the present invention, the water level in the upper layer of the processing tank gradually rises. When the floating frame is submerged, due to the self-locking of the spherical block, the floating frame will not rise. When the water level reaches the floating ball, through the total floating force of the floating ball and the floating frame, the floating frame can be driven to break away from the self-locking of the spherical block, so that the floating frame rises rapidly, forming an ascending energy storage operation, which further improves the cleaning effect of the filter plate; it solves the problem that when using the floating frame rising method for self-cleaning work, when the filter plate is blocked, the liquid level gradually rises, resulting in the floating frame can only rise gradually. When a part of the filter plate is cleaned, the blocked water source can be filtered out through this position, and a comprehensive cleaning of the filter plate cannot be formed.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1:

[0040] Refer to the appendix Figures 1 to 8 , a roof rainwater collection and utilization structure for green building design, including a water storage tank 1, a T-shaped collecting pipe 2 is fixedly connected to the water storage tank 1, and a row of collection mechanisms 3 are fixedly connected to the T-shaped collecting pipe 2;

[0041] By fixedly connecting a T-shaped collecting pipe 2 to the water storage tank 1 and installing a row of collection mechanisms 3 on the T-shaped collecting pipe 2, it is convenient to increase the rainwater collection range, and the rainwater is uniformly collected into the interior of the water storage tank 1 for storage through the T-shaped collecting pipe 2;

[0042] It should be noted here that the roof adopts a pitched roof design with a slope of 5-10 degrees to ensure that rainwater can quickly flow to the collection port

[0043] The collection mechanism 3 includes a processing tank 31 and a filter element 35 disposed inside the processing tank 31. The bottom of the processing tank 31 is internally connected to the T-shaped collecting pipe 2 through a drainage pipe. One side of the processing tank 31 is fixedly connected to an inclined slag discharge frame 32, and the bottom of the slag discharge frame 32 is fixedly connected to a slag discharge pipe 33;

[0044] By providing a filter element 35 inside the processing tank 31, it is used to filter the rainwater entering the inside of the processing tank 31, and the filtered filter residue is processed through the self-cleaning method of the filter element 35 itself, and is released and exported through the slag discharge frame 32 and the slag discharge pipe 33;

[0045] The top of the processing tank 31 is fixedly connected to a collecting pipe 34, and a driving member 36 is disposed inside the collecting pipe 34. The driving member 36 is used to self-clean the filter element 35 by utilizing the buoyancy and gravity of the water source;

[0046] Through the setting of the collecting pipe 34, it is used to collect the rainwater on the roof into the inside of the processing tank 31. Through the setting of the driving member 36, the self-cleaning work of the filter element 35 can be realized by utilizing the water storage driving force and the self-gravity after water storage when the filter element 35 is blocked;

[0047] It is effectively beneficial to block and collect the water source to realize the self-cleaning work of the filter element 35, which not only improves the energy conservation and environmental protection performance, but also enables the filter element 35 to self-start only when it is completely blocked or the filtration efficiency is lower than the rainwater collection rate, preventing the filter element 35 from being frequently cleaned, resulting in problems such as loosening between components and service life, and preventing the problem that the filter element 35 is not cleaned in time, affecting its rainwater collection and utilization effect.

[0048] Refer to the appendix Figure 7 and Figure 8 On the water storage tank 1, a water pump 4 is installed, and the suction port of the water pump 4 is fixedly connected to the inside of the water storage tank 1 through a suction pipe;

[0049] The water pump 4 is connected to an external power supply and control system, and is used to pump the rainwater stored inside the water storage tank 1 and transport it to the required position to form a rainwater utilization work;

[0050] One side of the water storage tank 1 is fixedly connected to a U-shaped scale tube 5 for displaying the water storage volume inside the water storage tank 1;

[0051] Through the setting of the U-shaped scale tube 5, it is convenient for users to intuitively understand the water storage volume situation inside the water storage tank 1;

[0052] A cleaning component is provided inside the water storage tank 1;

[0053] Through the setting of the cleaning component, it is used to clean the inside of the water storage tank 1 to improve the subsequent rainwater storage effect and the subsequent rainwater utilization range.

[0054] Refer to the attached Figure 7 and Figure 8 The dirt cleaning assembly includes a rotating shaft 6 rotatably connected to both sides of the inner wall of the water storage tank 1. A U-shaped scraper 7 is fixedly connected between the opposite ends of the two rotating shafts 6. One end of one of the rotating shafts 6 is equipped with a driving handle. The bottom of the water storage tank 1 is fixedly communicated with a collecting cover 8, and the bottom of the collecting cover 8 is fixedly communicated with a first sewage discharge pipe 9;

[0055] The two rotating shafts 6 are rotatably connected to the inside of the water storage tank 1 through the U-shaped scraper 7, so that by rotating the driving handle by the staff, the U-shaped scraper 7 can be driven to move along the inner surface of the water storage tank 1 to form the internal cleaning work of the water storage tank 1;

[0056] Through the setting of the collecting cover 8, it is used to collect and store the cleaned sewage, and is discharged and exported through the first sewage discharge pipe 9, further improving the internal cleaning effect of the water storage tank 1.

[0057] Refer to the attached Figure 7 and Figure 8 A cleaning block 10 is slidably connected inside the U-shaped scale tube 5, and a floating plate is fixedly connected to the bottom of the cleaning block 10. The bottom of the U-shaped scale tube 5 is fixedly communicated with a second sewage discharge pipe 11. Switch valves are installed on both the first sewage discharge pipe 9 and the second sewage discharge pipe 11;

[0058] By arranging the cleaning block 10 inside the U-shaped scale tube 5 and a floating plate at the bottom of the cleaning block 10, it is used to drive the cleaning block 10 to move up and down through the floating plate, realizing the self-cleaning work of the cleaning block 10 on the U-shaped scale tube 5, and preventing the problem of moss blockage inside the U-shaped scale tube 5, which affects subsequent water volume monitoring;

[0059] Through the setting of the second sewage discharge pipe 11, it is used to export the sewage removed inside the U-shaped scale tube 5.

[0060] Refer to the attached Figure 3 and Figure 4 The filter element 35 includes a filter plate 351 arranged in an inclined shape inside the treatment tank 31 and a driving plate 352 slidably connected inside the treatment tank 31 in a vertical sliding manner. The bottom of the driving plate 352 is slidably connected with a cleaning block 353 through a connecting frame, and the bottom of the cleaning block 353 is in contact with the top of the filter plate 351. The top end of the collecting pipe 34 is fixedly communicated with a hemispherical filter cover 356;

[0061] The filter plate 351 is provided to filter the rainwater entering the treatment box 31, thereby improving the subsequent rainwater utilization effect. The driving plate 352 is slidably connected to the treatment box 31 in an up-and-down sliding manner, so that the cleaning block 353 is driven to move downward by applying a downward driving force to the driving plate 352. Since the filter plate 351 is inclined, the cleaning block 353 slidably connected to the bottom of the driving plate 352 moves along the inclined surface of the filter plate 351, thereby performing a filter residue scraping and cleaning operation.

[0062] It should be noted here that the driving force for applying downward force to the driving plate 352 includes any electric mechanism or manual mechanism such as an electric telescopic rod and a motor that can drive the driving plate 352 up and down;

[0063] The hemispherical filter cover 356 is provided to filter large garbage such as leaves and branches at the rainwater collection port, and is provided in a hemispherical shape to increase the filtering range, thereby avoiding complete blockage and improving the water treatment performance.

[0064] See attached Figures 3 to 6 The driving member 36 includes a floating frame 361 and a gear member disposed inside the collecting tube 34, and the floating frame 361 is transmission-connected to the driving plate 352 via the gear member;

[0065] The driving member 36 includes a floating frame 361 and a gear member, so that the filter plate 351 is blocked to form a water accumulation force, so that the floating frame 361 rises, and the rising driving force of the floating frame 361 is transmitted to the driving plate 352 in the filter member 35 through the gear member, so that the cleaning block 353 automatically performs self-cleaning.

[0066] Embodiment 2: Based on embodiment 1, the difference is that;

[0067] See attached Figure 3 and Figure 4 One side of the filter plate 351 is rotatably connected to the inside of the processing box 31 through a rotating shaft, and the inside of the processing box 31 is rotatably connected with an inclined supporting plate 354, the top of the supporting plate 354 is used to support the other side of the filter plate 351, and the port of the slag discharge frame 32 is located between the filter plate 351 and the supporting plate 354, and an elastic member 355 is connected between the bottom of the supporting plate 354 and the bottom of the processing box 31, and the elastic member 355 includes a spring, a metal elastic sheet or other elastic material with elastic function;

[0068] The filter plate 351 is rotatably connected to the inside of the processing box 31 through a rotating shaft, and the bottom of the filter plate 351 is supported by a supporting plate 354. This not only ensures the normal filtering work of the filter plate 351 but also facilitates the cleaning of the top of the filter plate 351 by the cleaning block 353. When the cleaning block 353 moves to the end point, with the continuous downward pressure of the driving plate 352, the filter plate 351 and the supporting plate 354 can be driven to move downward in a fan shape, so that the filter residue on the converging side enters the slag discharge frame 32, realizing the function of automatically discharging the filter residue. Through the elastic extrusion of the elastic member 355 on the supporting plate 354, the supporting plate 354 and the filter plate 351 can be automatically reset, preventing the rainwater collected inside the processing box 31 from being exported through the slag discharge frame 32 and affecting the rainwater collection effect.

[0069] Embodiment 3: Different from Embodiment 1;

[0070] Refer to the appendix Figure 3 、 Figure 5 and Figure 6 , the gear member includes a conversion gear 362 rotatably connected to the inside of the collection pipe 34 through a rotating shaft, an upper layer plate 363 and a lower layer plate 364 slidably connected to the inside of the collection pipe 34. Tooth plates 365 meshing with the outer surface of the conversion gear 362 are fixedly connected to the bottom of the upper layer plate 363 and the top of the lower layer plate 364. The lower layer plate 364 is fixedly connected to the driving plate 352 through a first support rod, and the upper layer plate 363 is fixedly connected to the floating frame 361 through a second support rod;

[0071] When the filter plate 351 is blocked, the water level of the blockage will gradually rise. When the water level submerges the floating frame 361, the floating frame 361 can move upward, indirectly driving the upper layer plate 363 to rise. Since both tooth plates 365 mesh with the conversion gear 362 and the two tooth plates 365 are respectively connected to the upper layer plate 363 and the lower layer plate 364, when the upper layer plate 363 moves upward, the lower layer plate 364 can move downward, thereby driving the driving plate 352 in the filter member 35 to move downward. Cooperating with the cleaning block 353, the filter plate 351 can be self-cleaned. This effectively facilitates the self-cleaning of the filter member 35 by using the blocked and converged water source. It not only improves energy conservation and environmental protection but also enables the filter member 35 to self-start only when it is completely blocked or the filtering efficiency is lower than the rainwater collection rate, preventing problems such as loosening between components and service life due to frequent cleaning of the filter member 35, and preventing problems such as untimely cleaning of the filter member 35 affecting the rainwater collection and utilization effect;

[0072] The bottom of the floating frame 361 is fixedly connected with an annular gravity block 366, and at least one hemispherical card slot 367 is formed on the outer surface of the annular gravity block 366. At least one elastic telescopic rod 368 is fixedly connected to the inner surface of the collection pipe 34, and a spherical block 369 for inserting into the hemispherical card slot 367 is fixedly connected to the telescopic end of the elastic telescopic rod 368;

[0073] Through the arrangement of the annular gravity block 366, it is used to increase the gravity of the floating frame 361, so as to facilitate the subsequent rapid reset work of the floating frame 361. Here, it should be noted that the buoyancy of the floating frame 361 is greater than the gravity of the annular gravity block 366;

[0074] Through the arrangement of the elastic telescopic rod 368, it is used to drive the spherical block 369 to extend, so that the spherical block 369 is inserted into the hemispherical card slot 367, forming a self-locking of the annular gravity block 366 and the floating frame 361. Since both the spherical block 369 and the hemispherical card slot 367 are spherical in shape, not only can they be clamped, but also the clamping can be released by applying a driving force;

[0075] The top of the floating frame 361 is fixedly connected with a floating ball 3610 through a connecting rod. An annular auxiliary block 3611 is fixedly connected to the inner surface of the collection pipe 34. The floating frame 361 is conical, and a conical hole for the floating frame 361 to insert is formed inside the annular auxiliary block 3611;

[0076] Through the arrangement of the floating ball 3610, it is used to further increase the buoyancy of the floating frame 361, so that the floating frame 361 breaks away from the self-locking of the spherical block 369, forming a high-speed upward movement, thereby facilitating the rapid movement of the cleaning block 353 in the filter element 35 and improving the self-cleaning effect of the filter plate 351;

[0077] The specific principle is as follows: When the filter plate 351 is blocked, the water level in the upper layer of the treatment tank 31 gradually rises. When the floating frame 361 is submerged, due to the self-locking of the spherical block 369, the floating frame 361 will not rise. When the water level reaches the floating ball 3610, through the total buoyancy of the floating ball 3610 and the floating frame 361, the floating frame 361 can be driven to break away from the self-locking of the spherical block 369, so that the floating frame 361 rises rapidly, forming an upward energy storage work, and further improving the cleaning effect of the filter plate 351;

[0078] It solves the problem that when the self-cleaning work is carried out by using the rising method of the floating frame, when the filter plate is blocked, the liquid level gradually rises, resulting in the floating frame can only rise gradually. When a part of the filter plate is cleaned, the blocked water source can pass through this position for filtration, and the filter plate cannot be comprehensively cleaned;

[0079] Through the setting of the annular auxiliary block 3611, it is not only convenient to limit the floating frame 361 after rising, but also can form a water isolation operation in combination with the floating frame 361, which is not only convenient for storing the upper-layer water source in the collection pipe 34. When the water is stored to a certain pressure, and after the water source and filter residue inside the treatment tank 31 are cleaned, the water pressure can quickly lower the floating frame 361, forming the re-self-locking operation of the floating frame 361 and the reset operation of the cleaning block 353, improving the convenience of subsequent cyclic operations.

[0080] It should be noted that the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising said element.

[0081] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
