[0016] The beneficial effects of the present application are as follows: 1.

A cover plate 36 is rotatably disposed on one side of the upper end face of the auxiliary cylinder 13. The cover plate 36 is used to cover the opening.

[0024] In this embodiment, as Figure 2, Figure 3 , Figures 5-9 As shown, a connecting pipe 6 is fixedly connected to one side of the bottom of the storage tank 1, and a deodorizing box 5 is fixedly connected to one end of the connecting pipe 6. A drain pipe 8 is provided on one side of the deodorizing box 5, an activated carbon adsorption plate 7 is fixedly connected to one side of the inner wall of the deodorizing box 5, and a filter screen 2 is fixedly connected to one side of the top of the inner wall of the storage tank 1.

[0025] A motor 38 is fixedly connected to one side of the bottom of the storage tank 1, and the output end of the motor 38 is fixedly connected to one end of the stirring rod 37.

[0026] A motor 29 is fixedly connected to the middle of the upper surface of the support plate 12. The output end of the motor 29 is fixedly connected to the middle of the upper end of the auxiliary cylinder 13. A motor 30 is fixedly connected to one side of the upper end of the auxiliary cylinder 13. The output end of the motor 30 is fixedly connected to one end of the cover plate 36.

[0027] A gear 19 is rotatably mounted on one side of the outer wall of the auxiliary cylinder 13. The gear 19 meshes with the tooth blocks on the outer ring of the gear ring 20. A motor 18 is fixedly connected to one side of the outer wall of the auxiliary cylinder 13. The output end of the motor 18 is fixedly connected to the gear 19.

[0028] A spring 35 is fixedly connected to one side of the lifting ring 31, and the other end of the spring 35 is fixedly connected to the bottom of the auxiliary cylinder 13. An eccentric block 34 is rotatably set on one side of the lower end of the auxiliary cylinder 13. The eccentric block 34 is in contact with the lower surface of the lifting ring 31. A motor 6 33 is fixedly connected to one side of the lower end of the auxiliary cylinder 13. The output end of the motor 6 33 is fixedly connected to the middle of the eccentric block 34.

[0029] Specifically, in existing technologies, rainwater harvesting may involve acidic or alkaline conditions, requiring the addition of additives such as citric acid or baking soda for stirring and neutralization. However, this method has two drawbacks that affect efficiency: firstly, solid additives are usually added from a fixed location, which can easily lead to accumulation on the water surface, requiring prolonged stirring to achieve uniform mixing; secondly, additives may become damp and clump during storage, causing some additives to be trapped inside, making it difficult for them to come into contact with rainwater, resulting in low additive utilization and ultimately affecting the neutralization efficiency.

[0030] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Place the device in the designated position. Since the filter screen 2 is detachable, you can first remove the filter screen 2, put the appropriate amount of acidic additive and alkaline additive into the two additive boxes 11 respectively, and then put the filter screen 2 back in.

[0031] When it rains, rainwater falls into the storage tank 1, and the filter screen 2 filters out impurities in the rainwater. After the rainwater falls into the storage tank 1, the pH sensor 14 detects the acidity or alkalinity of the rainwater, and the system can automatically add acidic or alkaline additives based on the detection results. The auxiliary cylinder 13 is rotated by the motor 29, so that the top opening of the auxiliary cylinder 13 is aligned with the left or right feed port 28. Then the cover plate 36 is rotated by the motor 30, so that the opening is opened and the valve at the feed port 28 is opened, allowing the corresponding additive to fall into the auxiliary cylinder 13. Then the valve is closed, the cover plate 36 is reset, and each baffle 21 in the initial state covers a discharge hole 24, so the additive will not flow out of the auxiliary cylinder 13.

[0032] Then, motor 29 drives auxiliary cylinder 13 to rotate at high speed. When auxiliary cylinder 13 reaches a certain speed, motor 2 drives gear 19 to rotate, causing gear ring 20 and multiple baffles 21 to move away from discharge hole 24. The additive inside auxiliary cylinder 13 will then pass through discharge hole 24 under centrifugal force and be thrown towards the inner wall of storage tank 1. Since discharge hole 24 has multiple rows, the additive will be dispersed to various positions inside storage tank 1. Furthermore, when the additive passes through discharge hole 24, it will collide with blade 39, causing blade 39 to... The additives are cut to disperse any clumps until all additives are discharged from the auxiliary cylinder 13. Then, the motor 7 38 drives the stirring rod 37 to mix the additives and rainwater. Because the additives are dispersed throughout the storage tank 1, the stirring rod 37 only needs a short time to evenly mix the additives and rainwater. Furthermore, the cutting of clumps increases the contact area between the additives and rainwater, ensuring the utilization rate of the additives and thus improving the neutralization efficiency of the rainwater. The above operation is then repeated according to the change in the rainwater pH value, adding alkaline or acidic additives until the rainwater is neutral.

[0033] Then, the valve on the connecting pipe 6 is opened, allowing rainwater to enter the deodorization box 5 through the connecting pipe 6. After being deodorized by the activated carbon adsorption plate 7, it can be discharged from the drain pipe 8, thus realizing the reuse of rainwater.

[0034] However, in the above scheme, although the additive can be cut by the combined action of centrifugal force and blade 39, when the additive is adhesive, it may adhere to the surface of blade 39 during the throwing process, which will affect the subsequent cutting effect of blade 39. Therefore, in order to avoid this situation, while the auxiliary cylinder 13 is rotating, the motor 33 can drive the eccentric block 34 to rotate. When the distal end of the eccentric block 34 contacts the bottom of the lifting ring 31, the lifting ring 31 is at its highest point; when the proximal end of the eccentric block 34 contacts the bottom of the lifting ring 31, the lifting ring 31 will be at its lowest point under the action of spring 35. This makes the lifting ring 31 move up and down, and the additives adhering to the surface of blade 39 can be removed by the friction between blade 39 and the wall of discharge hole 24, thereby realizing the self-cleaning work of blade 39 and ensuring the subsequent cutting effect of blade 39.

[0035] In this embodiment, as Figures 2-4 As shown, it also includes a throw-out range control component; The throw range control assembly includes multiple traction rods 15, which are slidably connected to the storage tank 1 in the circumferential direction. One end of each traction rod 15 is fixedly connected to a traction plate 10, and a blocking pad 9 is fixedly connected between two adjacent traction plates 10. The blocking pad 9 is made of elastic material.

[0036] A rotating ring 3 is rotatably sleeved on one side of the outer wall of the storage tank 1. A connecting rod 4 is rotatably mounted on one end of the traction rod 15. One end of the connecting rod 4 is rotatably mounted on the rotating ring 3. A threaded rod 17 is threadedly connected to one end of the traction rod 15. One end of the threaded rod 17 is rotatably mounted on the storage tank 1. A motor 16 is fixedly connected to one side of the outer wall of the storage tank 1. The output end of the motor 16 is fixedly connected to one end of the threaded rod 17.

[0037] Specifically, in the above embodiments, although centrifugal force can be used to throw the additive out of the auxiliary cylinder 13 and disperse it in the inner cavity of the storage tank 1, when the rotation speed of the auxiliary cylinder 13 is constant, the distance the additive moves when it is thrown out will be fixed within a certain range, making it difficult for the additive to evenly cover the entire water surface diameter; on the other hand, if an attempt is made to control the throwing distance by reducing the rotation speed of the auxiliary cylinder 13, the additive may not be effectively thrown out due to insufficient centrifugal force, which will also affect the dispersion and cutting effect.

[0038] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: During the high-speed rotation of the auxiliary cylinder 13, the motor 16 drives the threaded rod 17 to reciprocate regularly, causing one side of the traction rod 15 to slide back and forth. The remaining traction rods 15 will also slide back and forth under the transmission of the connecting rod 4 and the rotating ring 3, thereby controlling the distance between the traction plate 10 and the axis of the storage tank 1. Since multiple blocking pads 9 cooperate to form a barrier, the size of the barrier changes when the traction plate 10 moves. When the additive is thrown out, it is first intercepted by the blocking pads 9, and then falls along the surface of the blocking pads 9 onto the water surface. This changes the falling range of the additive in real time, ensuring that the additive can evenly cover the entire diameter of the water surface, further guaranteeing the uniformity of additive dispersion and improving subsequent stirring efficiency.

[0039] In this embodiment, as Figures 9-11 As shown, it also includes an integrated scraping and unblocking component; The integrated scraping and unblocking component includes a rotating plate 23 rotatably disposed at the bottom of the inner cavity of the auxiliary cylinder 13. A scraper 22 is fixedly connected to one end of the rotating plate 23. The edge of the scraper 22 is in contact with the inner wall of the auxiliary cylinder 13. A cylinder 25 is fixedly connected to one side of the inner wall of the scraper 22. A connecting plate 27 is fixedly connected to the piston end of the cylinder 25. Multiple push blocks 26 are distributed longitudinally and fixedly connected to one side of the connecting plate 27. The push blocks 26 are matched with the specifications of the discharge hole 24, and multiple grooves matching the thickness of the blade 39 are provided on the push blocks 26.

[0040] A motor 32 is fixedly connected to the middle of the lower end face of the auxiliary cylinder 13, and the output end of the motor 32 is fixedly connected to one end of the rotating plate 23.

[0041] Specifically, in the above embodiments, although the additive can be thrown out by centrifugal force, when the additive has strong adhesion, the additive may stick firmly to the inner wall of the auxiliary cylinder 13. It is difficult to effectively discharge the additive by centrifugal force alone. In addition, the additive may stick to the wall of the discharge hole 24, thereby blocking the discharge hole 24 and affecting the subsequent discharge of the additive.

[0042] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: While the auxiliary cylinder 13 rotates, the motor 32 drives the rotating plate 23 to rotate, causing the scraper 22 to move in a circular motion along the inner wall of the auxiliary cylinder 13 to continuously scrape off the additives adhering to the inner wall of the auxiliary cylinder 13. This causes the additives to separate from the inner wall of the auxiliary cylinder 13, allowing the additives to be smoothly ejected. Furthermore, whenever the scraper 22 is aligned with a discharge hole 24, the scraper 22 stops moving, and the cylinder 25 drives the connecting plate 27 to move laterally, causing multiple push blocks 26 to pass through the discharge hole 24 simultaneously, pushing out the additives adhering to the hole wall of the discharge hole 24. This avoids the additives clogging the discharge hole 24 and ensures the smooth discharge of subsequent additives. Moreover, since the end of the push block 26 is provided with a groove that matches the thickness of the blade 39, the push block 26 will not interfere with the blade 39 when passing through the discharge hole 24.

[0043] Working principle: Place the device in the designated position. Since the filter screen 2 is detachable, it can be removed first. Place appropriate amounts of acidic and alkaline additives into the two additive boxes 11 respectively, and then reinstall the filter screen 2. When it rains, rainwater will fall into the storage tank 1. The filter screen 2 can filter impurities in the rainwater. After the rainwater falls into the storage tank 1, the pH sensor 14 can detect the acidity or alkalinity of the rainwater. The system can automatically add acidic or alkaline additives according to the detection results. The auxiliary cylinder 13 is rotated by motor 39, so that the top opening of the auxiliary cylinder 13 is aligned with the left or right feed port 28. Then, motor 430 drives the cover plate 36 to rotate, opening the opening and opening the valve at the feed port 28, allowing the corresponding additive to fall into the auxiliary cylinder 13. Then, the valve closes, the cover plate 36 returns to its original position, and each baffle 21 in the initial state covers a discharge hole 24, so the additive will not flow out of the auxiliary cylinder 13. Then, motor 29 drives auxiliary cylinder 13 to rotate at high speed. When auxiliary cylinder 13 reaches a certain speed, motor 2 drives gear 19 to rotate, causing gear ring 20 and multiple baffles 21 to move away from discharge hole 24. The additive inside auxiliary cylinder 13 will then pass through discharge hole 24 under centrifugal force and be thrown towards the inner wall of storage tank 1. Since discharge hole 24 has multiple rows, the additive will be dispersed to various positions inside storage tank 1. Furthermore, when the additive passes through discharge hole 24, it will collide with blade 39, causing blade 39 to... The additives are cut to disperse any clumps until all additives are discharged from the auxiliary cylinder 13. Then, motor 738 drives stirring rod 37 to mix the additives and rainwater. Because the additives are dispersed throughout the storage tank 1, stirring rod 37 only needs a short time to evenly mix the additives and rainwater. Furthermore, the cutting of clumps increases the contact area between the additives and rainwater, ensuring the utilization rate of the additives and improving the neutralization efficiency of the rainwater. The above operation is repeated according to the change in the rainwater pH value, adding alkaline or acidic additives until the rainwater is neutral. Then, the valve on connecting pipe 6 is opened, allowing the rainwater to enter the deodorization box 5 through connecting pipe 6. After deodorization by activated carbon adsorption plate 7, it can be discharged from drain pipe 8, thus realizing the reuse of rainwater.However, in the above scheme, although the additive can be cut by the combined action of centrifugal force and blade 39, when the additive is adhesive, it may adhere to the surface of blade 39 during the throwing process, which will affect the subsequent cutting effect of blade 39. Therefore, in order to avoid this situation, while the auxiliary cylinder 13 is rotating, the motor 33 can drive the eccentric block 34 to rotate. When the distal end of the eccentric block 34 contacts the bottom of the lifting ring 31, the lifting ring 31 is at its highest point; when the proximal end of the eccentric block 34 contacts the bottom of the lifting ring 31, the lifting ring 31 will be at its lowest point under the action of spring 35. This makes the lifting ring 31 move up and down, and the additives adhering to the surface of blade 39 can be removed by the friction between blade 39 and the wall of discharge hole 24, thereby realizing the self-cleaning work of blade 39 and ensuring the subsequent cutting effect of blade 39. During the high-speed rotation of the auxiliary cylinder 13, the motor 16 drives the threaded rod 17 to reciprocate regularly, causing one side of the traction rod 15 to slide back and forth. The remaining traction rods 15 will also slide back and forth under the transmission of the connecting rod 4 and the rotating ring 3, thereby controlling the distance between the traction plate 10 and the axis of the storage tank 1. Since multiple blocking pads 9 cooperate to form a barrier, the size of the barrier changes when the traction plate 10 moves. When the additive is thrown out, it is first intercepted by the blocking pads 9, and then falls along the surface of the blocking pads 9 onto the water surface. This changes the falling range of the additive in real time, ensuring that the additive can evenly cover the entire diameter of the water surface, further guaranteeing the uniformity of additive dispersion and improving subsequent stirring efficiency. While the auxiliary cylinder 13 rotates, the motor 32 drives the rotating plate 23 to rotate, causing the scraper 22 to move in a circular motion along the inner wall of the auxiliary cylinder 13 to continuously scrape off the additives adhering to the inner wall of the auxiliary cylinder 13. This causes the additives to separate from the inner wall of the auxiliary cylinder 13, allowing the additives to be smoothly ejected. Furthermore, whenever the scraper 22 is aligned with a discharge hole 24, the scraper 22 stops moving, and the cylinder 25 drives the connecting plate 27 to move laterally, causing multiple push blocks 26 to pass through the discharge hole 24 simultaneously, pushing out the additives adhering to the hole wall of the discharge hole 24. This avoids the additives clogging the discharge hole 24 and ensures the smooth discharge of subsequent additives. Moreover, since the end of the push block 26 is provided with a groove that matches the thickness of the blade 39, the push block 26 will not interfere with the blade 39 when passing through the discharge hole 24.
