[0021] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0022] Please see Figure 1-7 As shown in the figure, this embodiment provides a green building rainwater harvesting device, such as... Figure 1 As shown, it includes a rainwater storage chamber 1, and a buffer mixing chamber 2 is connected to the top of the rainwater storage chamber 1.
[0023] Combination Figure 2 As shown, a primary purification filter assembly 4 is fixedly installed at the connection between the rainwater storage chamber 1 and the buffer mixing chamber 2, and a secondary purification filter assembly 5 is fixedly installed on the top of the primary purification filter assembly 4; a primary recycling mechanism 3 is provided on the top of the buffer mixing chamber 2.
[0024] Combination Figure 3 As shown, the primary recycling mechanism 3 includes a circular cover ring 31 that is slidably connected to the top of the buffer mixing chamber 2. A flow equalization and stabilizing baffle 32 is fixedly connected to the upper inner side of the circular cover ring 31. Specifically, the circular cover ring 31 and the flow equalization and stabilizing baffle 32 enclose a certain water storage space in the upper part.
[0025] The bottom of the flow equalization and stabilizing baffle 32 is fixedly connected to a plurality of columnar filters 33, each of which has an opening at its top, and each of the columnar filters 33 has a piston-type spring float plate 34 installed inside in a sliding up-and-down state; in the initial state, the piston-type spring float plate 34 covers the opening of the columnar filter 33; when it rains, the piston-type spring float plate 34 slides downward, allowing rainwater to flow into the columnar filter 33.
[0026] Specifically, under normal conditions, multiple piston-type spring-loaded support plates 34 cover the top opening of the columnar filter 33 and are flush with the upper surface of the flow equalization and stabilization baffle 32. When rainwater enters the top of the circular cover ring 31 and the flow equalization and stabilization baffle 32, as the weight of the rainwater increases, it can press the piston-type spring-loaded support plates 34 downward to the interior of the columnar filter 33, allowing the rainwater to flow through the columnar filter 33 into the interior of the buffer mixing chamber 2, achieving preliminary impurity filtration of the rainwater. At the same time, after the rainwater enters the inner cavity of the buffer mixing chamber 2 after preliminary filtration, it is filtered again by the secondary purification filtration assembly 5 and the dynamic control mechanism 6, so that the double-filtered rainwater enters the interior of the rainwater storage chamber 1 for storage, improving the overall rainwater collection filtration effect; the above technical solution, through the flow equalization and stabilization baffle... Multiple columnar filters 33 are installed on the filter 32. Under normal conditions, the openings of the multiple columnar filters 33 are covered by piston-type spring float plates 34, preventing large debris such as leaves from entering the inner cavity of the columnar filters 33 and thus avoiding clogging. When it rains, rainwater first accumulates in the upper water storage space formed by the circular cover ring 31 and the flow equalization and stabilization baffle 32. At this time, if there are large debris such as leaves above the piston-type spring float plates 34 at the opening of the columnar filters 33, they will float up under the buoyancy of the rainwater, preventing the opening of the columnar filters 33 from being blocked. Even if some debris cannot float completely, a certain gap can be created between the debris and the opening to facilitate the flow of rainwater. In addition, setting the number of columnar filters 33 to multiple can also prevent all columnar filters 33 from being covered at the same time.
[0027] Furthermore, each of the multiple columnar filters 33 is provided with a lifting adjustment plate 35 at its bottom. The piston-type spring float plate 34 is fixedly connected to the lifting adjustment plate 35 through a connecting rod passing through the bottom of the columnar filter 33. When the piston-type spring float plate 34 slides up and down inside the columnar filter 33, the lifting adjustment plate 35 can slide up and down synchronously. When one end of the lifting adjustment plate 35 is in contact with the columnar filter 33, the piston-type spring float plate 34 is located above the opening of the columnar filter 33.
[0028] Specifically, a lifting adjustment plate 35 is fixedly connected to one end of the piston-type spring float plate 34 extending to the bottom of the columnar filter 33.
[0029] It should be noted that although the above technical solution can effectively avoid clogging, the method is relatively passive, and the effect is not ideal in the case of severe clogging. In addition, the recovered rainwater usually has a low oxygen content, which is not conducive to dissolving organic matter and various toxic substances, resulting in poor self-purification ability of the water body. At the same time, it is also not conducive to its use for water exchange for aquatic animals and irrigation of green plants. Therefore, a dynamic control mechanism 6 can be specifically designed, as detailed below:
[0030] Furthermore, referring to Figure 3-4 As shown, a dynamic control mechanism 6 is fixedly installed inside the rainwater storage chamber 1. The dynamic control mechanism 6 includes a hollow drive sleeve 61 fixedly installed at the bottom of the rainwater storage chamber 1. An electrically controlled telescopic drive rod 64 is fixedly installed inside the hollow drive sleeve 61. A load-bearing connecting bracket 65 is fixedly connected to the top of the electrically controlled telescopic drive rod 64. The top of the load-bearing connecting bracket 65 is fixedly connected to the flow equalization and stabilization baffle 32. The electrically controlled telescopic drive rod 64 can drive the load-bearing connecting bracket 65 to slide up and down, thereby driving the circular cover ring 31 to slide up and down in the buffer mixing chamber 2, and driving the piston-type spring float plate 34 to move up and down in and out of the columnar filter 33.
[0031] Understandably, when the electrically controlled telescopic drive rod 64 is activated for telescopic movement, it synchronously drives the load-bearing connecting bracket 65 to move up and down, thereby causing the circular cover ring 31 and the flow equalization stabilizing baffle 32 to move up and down synchronously. As the circular cover ring 31 slides down, the lifting adjustment plate 35 at the bottom of the columnar filter 33 comes into contact with the secondary purification filter assembly 5, stopping the lifting adjustment plate 35 from moving down. Simultaneously, this stops the piston-spring floating support plate 34, which is fixedly connected to it, from moving down. At this point, the circular cover ring 31 continues to slide down. When the circular cover ring 31 reaches its lowest point, the piston-spring floating support plate 34 is positioned above the opening of the columnar filter 33. When the circular cover ring 31 rises, the piston-spring... The float plate 34 then falls back into the cylindrical filter 33, thus achieving the reciprocating movement of the piston-spring float plate 34 inside and outside the cylindrical filter 33. During this process, the piston-spring float plate 34 not only actively lifts impurities from the inner cavity of the cylindrical filter 33 to the outside, preventing them from clogging the interior of the cylindrical filter 33, but also actively pushes open debris at the opening of the cylindrical filter 33, preventing blockage. Furthermore, during the reciprocating movement of the piston-spring float plate 34, fresh air from outside is continuously drawn into the buffer mixing chamber 2 through the cylindrical filter 33, allowing rainwater to continuously mix with fresh air and increasing the oxygen content in the rainwater.
[0032] Furthermore, the top of the hollow drive sleeve 61 is rotatably connected to the power transmission cylinder 62, the bearing connection bracket 65 passes through the power transmission cylinder 62, the bearing connection bracket 65 can slide up and down inside the power transmission cylinder 62, and the power transmission cylinder 62 can rotate around the bearing connection bracket 65.
[0033] Furthermore, referring to Figure 2-3 As shown, the outer wall of the power transmission cylinder 62 is provided with an elliptical trajectory circulation groove 63.
[0034] Combination Figure 5 As shown, the outer wall of the hollow drive sleeve 61 is provided with a plurality of through-type limiting sliding grooves 67. An L-shaped transmission plate 68 is slidably connected in one of the limiting sliding grooves 67. The lower end of the L-shaped transmission plate 68 is fixedly connected to the bottom of the bearing connecting bracket 65, and the upper end of the L-shaped transmission plate 68 is fixedly connected to a trajectory drive rod 69. The trajectory drive rod 69 is slidably connected in the elliptical trajectory circulation groove 63.
[0035] At the same time, refer to Figure 3 As shown, the top of the power transmission cylinder 62 is rotatably connected to a fluid drive blade 66 located above the secondary purification filter assembly 5. When the bearing connecting bracket 65 slides up and down, it can simultaneously drive the fluid drive blade 66 to rotate.
[0036] It can be understood that when the supporting bracket 65 moves up and down under force, it can also drive the L-shaped transmission plate 68 to move up and down simultaneously, thereby driving the trajectory drive rod 69 to slide in the inner cavity of the elliptical trajectory circulation groove 63. This allows the power transmission cylinder 62 to rotate synchronously, which in turn drives the fluid drive blade 66 above the power transmission cylinder 62 to rotate. In this process, the rotating fluid drive blade 66 can not only scrape off the impurities accumulated on the surface of the secondary purification filter component 5, preventing impurities from covering the surface and affecting the filtration efficiency of the primary purification filter component 4 and the secondary purification filter component 5, but also stir the rainwater in the buffer mixing chamber 2, causing the rainwater to form a vortex in the buffer mixing chamber 2. This allows the rainwater to mix more fully with the constantly replenished fresh air, further increasing the oxygen content in the rainwater and greatly improving the quality of the recycled rainwater.
[0037] More preferably, refer to Figure 5 and Figure 7 As shown, a spraying mechanism 7 is also fixedly installed inside the rainwater storage chamber 1. The spraying mechanism 7 includes multiple primary balance support frames 71 fixedly installed on the outer wall of the electrically controlled telescopic drive rod 64. The multiple primary balance support frames 71 are slidably installed inside the limiting sliding groove 67, and a secondary balance support frame 72 is fixedly installed on one side of the multiple primary balance support frames 71 extending out of the outer wall of the hollow drive sleeve 61.
[0038] Specifically, the purpose of this design is that when the electrically controlled telescopic drive rod 64 is activated to perform telescopic movement, the mutual limiting of multiple primary balance support frames 71 and limit sliding grooves 67, combined with the synchronous connection of secondary balance support frames 72, makes the overall up-and-down reciprocating movement of the load-bearing connecting bracket 65 more stable and smooth.
[0039] At the same time, combined Figure 7As shown, multiple liquid storage cylinders 74 are fixedly installed on the inner wall of the rainwater storage chamber 1. Multiple drive piston rods 73, which are slidably connected to the liquid storage cylinders 74, are fixedly installed on the top of the secondary balance support frame 72. The inner cavities of the multiple liquid storage cylinders 74 are filled with chemical agents. The tops of the liquid storage cylinders 74 are respectively connected to liquid inlet pipes 75 and liquid outlet pipes 76.
[0040] Specifically, the liquid inlet pipe 75 is connected to the external chemical agent replenishment port, which facilitates the timely replenishment of chemical agents into the inner cavity of the liquid storage cylinder 74. The chemical agents may include coagulants, coagulant aids, pH adjusters, oxidizing disinfectants, etc., which are not limited in this application.
[0041] Meanwhile, one-way valves are fixedly installed at the connection points between the liquid inlet pipe 75 and the liquid outlet pipe 76 and the liquid storage cylinder 74.
[0042] Specifically, in actual use, when the electrically controlled telescopic drive rod 64 drives the primary balance support frame 71, the secondary balance support frame 72, and multiple drive piston rods 73 to move up and down reciprocally, the chemical agent in the inner cavity of the liquid storage cylinder 74 can be quantitatively sprayed from the liquid outlet pipe 76 into the inner cavity of the rainwater storage chamber 1, and external chemical agents can be drawn from the liquid inlet pipe 75 to replenish the inner cavity of the liquid storage cylinder 74 in a timely manner. Thus, during the rainwater collection process, chemical agents are added to the inner cavity of the rainwater storage chamber 1 in a quantitative manner to mix with the rainwater, thereby improving water quality and treatment effect.
[0043] Furthermore, the plurality of liquid storage cylinders 74 and the driving piston rod 73 are arranged in a one-to-one correspondence, and the plurality of liquid storage cylinders 74 are arranged in a ring-shaped, equidistant manner around the inner circumferential surface of the rainwater storage chamber 1.
[0044] Specifically, the purpose of this design is to ensure that the chemical agent sprayed by the up-and-down movement of the drive piston rod 73 can be evenly sprayed from multiple directions within the inner cavity of the rainwater storage chamber 1, so that the chemical agent can come into more comprehensive contact with the rainwater, thereby facilitating the full integration of the rainwater and the chemical agent.
[0045] At the same time, combined Figure 5 As shown, the secondary balance support frame 72 has multiple threaded drive rods 77 internally threaded, and the bottom of each of the multiple threaded drive rods 77 is fixedly installed with mixing and stirring blades 78 that are rotatably connected to the rainwater storage chamber 1.
[0046] Specifically, under normal conditions, the secondary balance support frame 72 moves to the top position of multiple threaded drive rods 77. When the electrically controlled telescopic drive rod 64 retracts and drives the secondary balance support frame 72 to move downward, the threaded drive rods 77 can drive the mixing and stirring blades 78 to rotate as a whole. This causes the mixing and stirring blades 78 to stir the rainwater in the inner cavity of the rainwater storage chamber 1, so that it can be fully mixed with the chemical agent and improve the overall rainwater quality.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
