Description

Technical Field

[0001] This application relates to the field of rainwater pretreatment technology, and in particular to a multifunctional rainwater pretreatment device. Background Technology

[0002] With the increasing scarcity of water resources, people are gradually realizing the importance of rainwater harvesting and reuse. After rainwater is collected, it needs to be pre-treated to meet usage requirements.

[0003] In related technologies, rainwater pretreatment devices include a well casing with an inlet and an outlet on each side. A diversion outlet is located at the lower part of the well casing's sidewall, and an overflow outlet is located at the upper part of the sidewall. A baffle is also installed inside the well casing, vertically connected to the bottom, with the baffle positioned near the outlet. One end of the baffle is connected to a perforated plate, which is inclined towards the inlet. When it rains, rainwater enters the well casing through the inlet. Initially, rainwater is diverted through the diversion outlet until the designed diversion volume is reached, at which point the diversion outlet is closed. When the water level inside the well casing exceeds the baffle level, rainwater flows out through the perforated plate and is collected at the outlet. If the water volume is too large and the water level rises to the overflow outlet height, excess rainwater is discharged from the overflow outlet.

[0004] Regarding the aforementioned technologies, when rainwater passes through the perforated plate, the perforated plate can filter and intercept garbage and floating objects in the rainwater, but toxic substances in the rainwater are not easily removed. Summary of the Invention

[0005] To facilitate the addition of disinfectant into the well casing and achieve the effect of disinfecting rainwater, this application provides a multi-functional rainwater pretreatment device.

[0006] The multi-functional rainwater pretreatment device provided in this application adopts the following technical solution:

[0007] A multi-functional rainwater pretreatment device includes a well shaft, an inlet on one side of the well shaft, and an outlet on the side of the well shaft away from the inlet. A storage tank for storing disinfectant is installed on the well shaft. An outlet is provided on the top wall of the well shaft, and the outlet is connected to the storage tank. An opening / closing plate for opening and closing the outlet is slidably installed inside the well shaft. A conveyor chain is installed inside the well shaft, located below the outlet. A receiving box is installed on the conveyor chain and is conveyed by the conveyor chain. An adjusting component is provided on the receiving box for adjusting the opening / closing plate to open and close the outlet. A driving component for driving the conveyor chain is installed inside the well shaft.

[0008] By adopting the above technical solution, the drive component drives the conveyor chain to work. The conveyor chain transports the receiving box. When the opening of the receiving box is below the dispensing port, the adjustment component drives the opening and closing plate to open the dispensing port. The disinfectant in the storage tank falls into the receiving box through the dispensing port. Then, the adjustment component adjusts the opening and closing plate to close the dispensing port. When the conveyor chain transports the receiving box to the end of the conveyor chain, the receiving box tilts and pours the disinfectant inside into the well, which helps to disinfect rainwater. At the same time, by using the conveyor chain to transport the receiving box, it moves to the dispensing port after one round, which helps to intermittently add disinfectant into the well, so that the disinfectant in the well is not too high and wasteful, nor too low and can ensure the disinfection effect.

[0009] Preferably, the sliding direction of the opening and closing plate is parallel to the transmission direction of the conveyor chain. The adjusting assembly includes an abutment plate slidably disposed on the receiving box, a magnet disposed inside the well shaft, an iron block disposed on the side of the abutment plate near the conveyor chain, a pushing member disposed on the receiving box, and a pulling member disposed on the well shaft. The abutment plate is located on the side of the receiving box near the transmission direction of the conveyor chain, and the side of the abutment plate away from the receiving box is used to abut against the opening and closing plate. The abutment plate slides in a direction close to or away from the conveyor chain. The magnet is located between the conveyor chains and is used to attract and cooperate with the iron block to drive the abutment plate to slide in a direction close to the conveyor chain. The pushing member is used to push the abutment plate to slide in a direction away from the conveyor chain, and the pulling member is used to pull the opening and closing plate to slide in a direction opposite to the transmission direction of the conveyor chain.

[0010] By adopting the above technical solution, when the conveyor chain moves the receiving box to the side of the opening and closing plate away from the conveyor chain's direction, the abutment plate on the receiving box abuts against the opening and closing plate. As the receiving box continues to move, the abutment plate pushes the opening and closing plate to slide away from the outlet to open the outlet. At this time, the receiving box is located below the outlet to receive the dropped disinfectant. When the receiving box moves the abutment plate to the magnet, the magnet attracts the iron block, causing the iron block to move the abutment plate towards the conveyor chain. The abutment plate separates from the opening and closing plate. At this time, the pulling component pulls the opening and closing plate towards the outlet to close the outlet. As the receiving box continues to move, it causes the iron block on the abutment plate to separate from the magnet. At this time, the pushing component pushes the abutment plate to slide away from the conveyor chain to reset. Then, the conveyor chain transports the receiving box to the end, and the receiving box tilts to drop the disinfectant into the well, thus achieving disinfection of rainwater.

[0011] Preferably, the pushing member includes a spring for pushing the abutment plate to slide in a direction away from the conveyor chain. One end of the spring is disposed on the medicine receiving box, and the other end is disposed on the abutment plate. The attraction force between the magnet and the iron block is greater than the pushing force of the spring.

[0012] By adopting the above technical solution, the spring pushes the abutment plate to slide away from the conveyor chain, so as to reset the abutment plate and facilitate the next sliding of the opening and closing plate by the abutment plate.

[0013] Preferably, the pulling component includes a tension spring, which is used to pull the opening and closing plate to slide toward a side opposite to the conveying direction of the conveyor chain. One end of the tension spring is disposed on the well shaft, and the other end is disposed on the opening and closing plate.

[0014] By adopting the above technical solution, the opening and closing plate is pulled by the tension spring to slide towards the direction of the medicine outlet, so that the opening and closing plate closes the medicine outlet and the disinfectant in the medicine storage box is not easy to leak.

[0015] Preferably, the magnet is slidably disposed on the inner wall of the well shaft, and the sliding direction of the magnet is parallel to the sliding direction of the opening and closing plate. A float is slidably disposed inside the well shaft, and the sliding direction of the float is arranged in the vertical direction. A first transmission component is disposed inside the well shaft to drive the magnet to move when the float slides. When the float moves upward, the sliding direction of the magnet is consistent with the transmission direction of the conveyor chain.

[0016] By adopting the above technical solution, when the amount of rainwater in the well is large and the water level rises, the rainwater drives the float to move upward. At this time, the first transmission component drives the magnet to move in the same direction as the transmission chain, so that when the magnet attracts the iron block on the contact plate, the sliding distance of the opening and closing plate is large, which increases the degree of opening of the outlet. This is conducive to increasing the amount of disinfectant, so that the amount of disinfectant added can be adjusted in time according to the amount of rainwater in the well, ensuring the disinfection effect while reducing waste, and providing convenience for disinfecting rainwater.

[0017] Preferably, the first transmission component includes a screw rotatably disposed inside the wellbore, a gear sleeved on the screw, and a rack disposed on the float. The rotation axis of the screw is parallel to the sliding direction of the magnet. A fixed rod is connected to the magnet and threadedly connected to the screw. The rack and the gear mesh.

[0018] By adopting the above technical solution, when the float slides, it drives the rack to move up and down. The rack drives the gear to rotate, which in turn drives the screw to rotate. The screw drives the fixed rod to slide the magnet, so as to adjust the opening degree of the medicine outlet according to the amount of rainwater in the well, that is, to adjust the amount of disinfectant in the medicine receiving box, which helps to ensure the disinfection effect and reduce waste.

[0019] Preferably, the conveyor chain includes two drive rollers rotating inside the well shaft, sprockets respectively sleeved at both ends of the drive rollers, and a chain wound around the sprockets on the same side. The rotation axis of the drive rollers is perpendicular to the sliding direction of the opening and closing plate. The medicine receiving box is disposed on the opposite chain. The drive assembly includes a first impeller rotatably disposed at the water outlet and a second transmission component disposed on the well shaft. The rotation axis of the first impeller is parallel to the rotation axis of the drive rollers. The second transmission component is used to drive the drive rollers to rotate when the first impeller rotates.

[0020] By adopting the above technical solution, when rainwater flows out of the outlet in the well, it drives the first impeller at the outlet to rotate. The second transmission component causes the first impeller to rotate, which in turn drives the transmission roller to rotate, thereby realizing the transmission of the chain so that the chain can drive the medicine receiving box to move. The first impeller is used to realize the operation of the conveyor chain so that the conveyor chain can be started in time when it rains, and disinfectant can be added into the well in time.

[0021] Preferably, a rotating shaft is coaxially arranged on the first impeller, and the rotating shaft rotatably passes through the well casing. A connecting rod is coaxially arranged on any of the transmission rollers, and the connecting rod rotatably passes through the well casing. The second transmission component includes a first pulley sleeved on the rotating shaft and the connecting rod at one end outside the well casing, and a first belt wound around the first pulley. The two first pulleys are connected by the first belt drive.

[0022] By adopting the above technical solution, when the first impeller rotates, it drives the rotating shaft to rotate. Through the transmission of the first pulley and the first belt, the connecting rod and the transmission roller are rotated, thereby enabling the sprocket to drive the chain transmission, so that the chain can drive the medicine receiving box to move, which helps to sprinkle the disinfectant into the rainwater in the well.

[0023] Preferably, a stirring shaft is rotatably installed inside the wellbore, the axis of rotation of the stirring shaft is perpendicular to the sliding direction of the float, the stirring shaft is provided with stirring blades, and a rotating component for driving the stirring shaft to rotate is provided inside the wellbore.

[0024] By adopting the above technical solution, the rotating component drives the stirring shaft to rotate, and the stirring shaft drives the stirring blades to rotate, which stirs the rainwater in the well, thereby facilitating the mixing of disinfectant and rainwater and improving the disinfection effect.

[0025] Preferably, the rotating component includes a second impeller rotatably disposed at the water inlet, a rotating rod coaxially connected to the second impeller, a second pulley sleeved on the rotating rod and the stirring shaft, and a second belt wound around the second pulley. The rotation axis of the second impeller is parallel to the rotation axis of the stirring shaft, and the two second pulleys are connected by a second belt drive.

[0026] By adopting the above technical solution, when rainwater enters the well shaft from the inlet, it drives the second impeller to rotate. At this time, through the transmission of the second pulley and the second belt, the second impeller drives the stirring shaft to rotate, so that the stirring blades can mix the disinfectant and rainwater evenly and improve the disinfection effect.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] The drive component drives the conveyor chain to work, and the conveyor chain transports the medicine receiving box. When the opening of the medicine receiving box is below the medicine outlet, the adjustment component drives the opening and closing plate to open the medicine outlet. The disinfectant in the medicine storage tank falls into the medicine receiving box through the medicine outlet. Then the adjustment component adjusts the opening and closing plate to close the medicine outlet. When the conveyor chain transports the medicine receiving box to the end of the conveyor chain, the medicine receiving box tilts and pours the disinfectant inside into the well, which helps to disinfect the rainwater.

[0029] When the amount of rainwater in the well is large and the water level rises, the rainwater causes the float to move upward. At this time, the first transmission component drives the magnet to move in the same direction as the transmission chain, so that when the magnet attracts the iron block on the contact plate, the sliding distance of the opening and closing plate is large, which increases the degree of opening of the discharge port. This helps to increase the amount of disinfectant, so that the amount of disinfectant added can be adjusted in time according to the amount of rainwater in the well, ensuring the disinfection effect while reducing waste, and providing convenience for disinfecting rainwater.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a multifunctional rainwater pretreatment device. (Refer to...) Figure 1 and Figure 2 The rainwater multi-functional pretreatment device includes a well shaft 1, an inlet 2 located on one side of the well shaft 1, and an outlet 3 located on the side of the well shaft 1 away from the inlet 2. A well hole 19 is provided on the top wall of the well shaft 1, and a well cover 20 is provided on the well hole 19 to facilitate maintenance by workers. A baffle 21 is fixedly connected to the bottom wall of the well shaft 1 near the outlet 3, and a perforated plate 22 is fixed above the baffle 21. A sedimentation tank 23 is fixedly installed on the side of the well shaft 1 near the outlet 3. The sedimentation tank 23 is connected to the well shaft 1 through the outlet 3. A water outlet pipe 24 is connected to the side of the sedimentation tank 23 away from the outlet 3 to facilitate rainwater collection. A medicine storage tank 4 for storing disinfectant is fixedly connected to the well shaft 1. The medicine storage tank 4 is located on the top wall of the well shaft 1 near the outlet 3. A medicine inlet pipe 25 is connected to the top wall of the medicine storage tank 4, and a screw cap 26 is screwed onto the medicine inlet pipe 25 to facilitate the addition of disinfectant to the medicine storage tank 4.

[0038] Reference Figure 2 and Figure 3The top wall of the well shaft 1 has a medicine outlet 5 communicating with the medicine storage tank 4. The medicine outlet 5 has a rectangular cross-section. An opening / closing plate 6 for opening and closing the medicine outlet 5 is slidably installed on the inner side of the top wall of the well shaft 1. The sliding direction of the opening / closing plate 6 is parallel to the arrangement direction of the water inlet 2 and the water outlet 3. A guide block 27 is fixedly attached to the side of the opening / closing plate 6 closest to the medicine storage tank 4. Two guide blocks 27 are located on both sides of the medicine outlet 5. The longitudinal section of the guide block 27 is T-shaped. Guide grooves 28 that slide and engage with the guide blocks 27 are respectively opened on the top wall of the well shaft 1. Two sets of support plates 29 are fixedly connected to the top wall of the well shaft 1. The two sets of support plates 29 are located on both sides of the medicine outlet 5. A conveyor chain 7 is fixedly installed inside the well shaft 1. The conveyor chain is located above the water-passing perforated plate 22 and below the opening / closing plate 6. The conveyor chain 7 includes two rotating sections... The transmission roller 71 between the support plates 29, the sprockets 72 respectively fixedly sleeved at both ends of the transmission roller 71, and the chain 73 wound around the sprocket 72 on the same side are arranged in a manner that is as follows: the rotation axis of the transmission roller 71 is perpendicular to the sliding direction of the opening and closing plate 6, and the transmission direction of the chain 73 is parallel to the sliding direction of the opening and closing plate 6. In this embodiment, the chain 73 is transmitted in the direction close to the water inlet 2. A medicine receiving box 8 is fixed between the two opposing chains 73. The medicine receiving box 8 is an elastic plastic box to facilitate transmission of a full circle. The medicine receiving box 8 is located below the medicine outlet 5. The cross-section of the medicine receiving box 8 is rectangular, and the cross-sectional area of ​​the medicine receiving box 8 is larger than the cross-sectional area of ​​the medicine outlet 5. An adjustment component 9 for adjusting the opening and closing of the medicine outlet 5 by the opening and closing plate 6 is provided on the medicine receiving box 8. A drive component 10 for driving the transmission roller 71 to rotate is provided inside the well shaft 1.

[0039] Reference Figure 2 and Figure 4To facilitate the rotation of the transmission roller 71, the drive assembly 10 includes a first impeller 101 rotatably mounted on the inner wall of the outlet 3 and a second transmission component 102 mounted on the well shaft 1. The rotation axis of the first impeller 101 is parallel to the rotation axis of the transmission roller 71. When rainwater from the outlet 3 impacts the first impeller 101, the first impeller 101 rotates towards the direction closer to the inlet 2. An L-shaped baffle 37 is fixed on the inner wall of the well shaft 1 on the side closer to the outlet 3. The baffle 37 covers the upper side of the first impeller 101 to ensure that rainwater pushes the first impeller 101 to rotate towards the direction closer to the inlet 2. A rotating shaft 14 is coaxially fixed to the first impeller 101, and the rotating shaft 14 rotatably passes through the well shaft 1. The second transmission component 102 is used to drive the transmission roller 71 to rotate when the first impeller 101 rotates. A connecting rod 15 is coaxially fixed to the transmission roller 71 near the outlet 3, and the connecting rod 15 rotatably passes through the well shaft 1. The second transmission component 102 includes a first pulley 1021 respectively sleeved on the rotating shaft 14 and the connecting rod 15 at the outer end of the well shaft 1, and a first belt 1022 wound around the first pulley 1021. The two first pulleys 1021 are connected by the first belt 1022. In other embodiments, the drive component 10 can be replaced by a motor installed in the well shaft. The motor drives the transmission roller 71 to rotate, which can also drive the chain 73 to move the medicine box 8.

[0040] When it rains, rainwater enters the well shaft 1 through inlet 2. Initially, the rainwater is diverted through the diversion outlet, which is then closed. When the water level in the well shaft 1 is higher than the baffle 21, the rainwater flows out through the perforated plate 22 from the outlet 3. At this time, the rainwater passing through the outlet 3 drives the first impeller 101 to rotate. The first impeller 101 drives the rotating shaft 14 to rotate. Through the transmission of the first pulley 1021 and the first belt 1022, the connecting rod 15 drives the transmission roller 71 to rotate, thereby causing the chain 73 to drive the medicine receiving box 8 towards the direction closer to the inlet 2. When the medicine receiving box 8 moves to the side of the opening and closing plate 6 near the outlet 3, the opening and closing plate 6 is slid towards the direction closer to the inlet 2 by the adjusting component 9, opening the medicine outlet 5. At this time, the medicine storage tank 4 contains... Disinfectant falls into the receiving box 8. As the receiving box 8 continues to move away from the outlet 5, the adjusting component 9 adjusts the opening and closing plate 6 to slide towards the outlet 3, sealing the outlet 5 and preventing leakage of disinfectant from the storage tank 4. Then, the chain 73 moves the receiving box 8 to the drive roller 71 near the inlet 2. The receiving box 8 tilts, and the disinfectant inside is sprayed into the well shaft 1, thus helping to disinfect the rainwater in the well shaft 1. The disinfected rainwater then enters the sedimentation tank 23 through the perforated plate 22 and the outlet 3 for sedimentation. The perforated plate 22 filters out scum from the disinfected rainwater, thus achieving the device's multi-functionality. The settled rainwater then flows out from the outlet pipe 24 for collection. Using the chain 73 to move the receiving box 8 helps to intermittently spray disinfectant into the well shaft 1, ensuring disinfection effectiveness while reducing waste.

[0041] Reference Figure 2 and Figure 3To facilitate the adjustment of the opening and closing plate 6 in the direction of sliding towards or away from the medicine outlet 5, the adjustment assembly 9 includes an abutment plate 91 slidably disposed on the outer wall of the medicine receiving box 8, a magnet 92 disposed in the well shaft 1, an iron block 93 disposed on the side of the abutment plate 91 near the conveyor chain 7, a pusher 94 disposed on the medicine receiving box 8, and a puller 95 disposed in the guide groove 28. When the opening of the medicine receiving box 8 is upward, the abutment plate 91 is located on the side of the medicine receiving box 8 near the water inlet 2, and the side of the abutment plate 91 away from the medicine receiving box 8 is used to abut against the side of the opening and closing plate 6 near the water outlet 3. The abutment plate 91 slides towards or away from the chain 73. When the opening of the medicine receiving box 8 is upward, the sliding direction of the abutment plate 91 is set in the vertical direction. Two telescopic rods 30 are fixed on the side of the abutment plate 91 near the chain 73. The extension direction of the telescopic rods 30 is parallel to the sliding direction of the abutment plate 91. The side of the telescopic rods 30 away from the abutment plate 91 is fixed to the side wall of the medicine receiving box 8. Above, magnet 92 is located between chains 73. A fixing rod 13 is fixedly connected to one side of magnet 92. The fixing rod 13 is connected to the inner wall of well 1. The length direction of the fixing rod 13 is parallel to the rotation axis of transmission roller 71. Iron block 93 is located between the two telescopic rods 30. Magnet 92 is used to attract and cooperate with iron block 93 to drive the abutment plate 91 to slide towards the direction closer to the transmission chain 7. When the opening of medicine box 8 is upward and the abutment plate 91 is away from magnet 92, the horizontal plane of iron block 93 near chain 73 is a certain distance from the horizontal plane of magnet 92 near opening and closing plate 6. A fixing block 38 is fixed on the side of magnet 92 away from medicine storage box 4, so that when medicine box 8 is transmitted to the lower side of transmission roller 71, magnet 92 is not easy to attract iron block 93. Pushing member 94 is used to push abutment plate 91 to slide away from transmission chain 7. Pulling member 95 is used to pull opening and closing plate 6 to slide towards the direction closer to water outlet 3, that is, away from the transmission direction of chain 73.

[0042] Reference Figure 2 and Figure 3 The pushing component 94 includes a spring 941 for pushing the abutment plate 91 to slide away from the conveyor chain 7. The spring 941 and the telescopic rod 30 correspond one-to-one. The spring 941 is movably sleeved on the corresponding telescopic rod 30. The extension direction of the spring 941 is parallel to the sliding direction of the abutment plate 91. One end of the spring 941 is fixedly connected to the medicine box 8, and the other end is fixedly connected to the side of the abutment plate 91 near the chain 73. The attraction force of the magnet 92 and the iron block 93 is greater than the pushing force of the spring 941.

[0043] Reference Figure 2 and Figure 3 The pulling component 95 includes a tension spring 951 for pulling the opening and closing plate 6 to slide towards the water outlet 3. The tension spring 951 and the guide block 27 correspond one-to-one. One end of the tension spring 951 is fixed to the side wall of the guide groove 28 near the water outlet 3, and the other end is fixedly connected to the guide block 27 near the water outlet 3.

[0044] When chain 73 moves the medicine receiving box 8 to the side of the opening and closing plate 6 near the outlet 3, the side of the abutment plate 91 away from the medicine receiving box 8 abuts against the opening and closing plate 6, pushing the opening and closing plate 6 to gradually open the medicine outlet 5. At this time, the tension spring 951 is stretched, and the disinfectant in the medicine storage tank 4 falls into the medicine receiving box 8. When chain 73 moves the medicine receiving box 8 and the abutment plate 91 to the magnet 92, the magnet 92 attracts the iron block 93, causing the abutment plate 91 to slide towards the conveyor chain 7, compressing the spring 941, and the abutment plate 91 and The opening and closing plate 6 disengages, and then the tension spring 951 pulls the opening and closing plate 6 to slide towards the water outlet 3, closing the medicine outlet 5. Then, as the chain 73 continues to drive, it drives the iron block 93 and magnet 92 on the abutment plate 91 to disengage. At this time, the spring 941 pushes the abutment plate 91 to slide away from the chain 73 to reset, thereby realizing the adjustment of the opening and closing plate 6 to open and close the medicine outlet 5. This makes it convenient for the medicine outlet 5 to open when the medicine receiving box 8 moves below the medicine outlet 5, providing convenience for disinfecting rainwater in the well shaft 1.

[0045] Reference Figure 3 and Figure 4 A slider 31 is fixed to the end of the fixed rod 13 away from the magnet 92. The slider 31 slides on the inner wall of the well shaft 1. A groove 32 is provided on the inner wall of the well shaft 1 to slide with the slider 31. The sliding direction of the slider 31 is parallel to the sliding direction of the opening and closing plate 6. A float 11 is slidably arranged inside the well shaft 1. The sliding direction of the float 11 is set vertically. The float 11 is located at the water-passing perforated plate 22 (refer to...). Figure 2 On the side away from the outlet 3, a counterweight 33 is fixedly connected to the bottom wall of the float 11, and a protrusion 34 is fixedly connected to the counterweight 33. A groove 35 is provided on the inner wall of the well shaft 1 to slide with the protrusion 34 (see reference). Figure 2 The well shaft 1 is equipped with a first transmission component 12 for moving the magnet 92 when the float 11 slides. When the float 11 moves upward, the sliding direction of the magnet 92 is consistent with the transmission direction of the chain 73.

[0046] Reference Figure 3 and Figure 4 To facilitate the sliding of the float 11 and the magnet 92, the first transmission component 12 includes a screw 121 rotatably disposed inside the well casing 1, a gear 122 fixedly sleeved on the screw 121, and a rack 123 fixedly connected to the top wall of the float 11. The rotation axis of the screw 121 is parallel to the sliding direction of the magnet 92. The fixing rod 13 is threadedly connected to the screw 121. The rack 123 and the gear 122 mesh. An extension cylinder 36 is connected to the top wall of the well casing 1. The position of the extension cylinder 36 corresponds to the position of the rack 123, providing space for the rack 123 to slide upward.

[0047] When the water level in well 1 is higher than that at baffle 21, rainwater causes float 11 to lift counterweight 33. At this time, rack 123 moves upward, driving gear 122 to rotate, which in turn rotates screw 121. The rotation of screw 121 drives fixed rod 13 to slide magnet 92 towards the direction closer to inlet 2, that is, towards the side consistent with the transmission direction of chain 73. This increases the horizontal distance from the side of medicine outlet 5 near water outlet 3 to magnet 92. As a result, when medicine receiving box 8 drives abutment plate 91 past below medicine outlet 5, the abutment plate 91 pushes the opening and closing plate 6 a greater distance, thus increasing the degree to which medicine outlet 5 opens. More disinfectant falls into the collection box 8, which helps ensure the disinfection effect. When the water level in the well 1 drops, the counterweight 33 drives the float 11 to move down. At this time, the rack 123 drives the gear 122 and the screw 121 to rotate in opposite directions, so that the screw 121 drives the fixed rod 13 to slide the magnet 92 towards the direction closer to the outlet 3, reducing the horizontal distance between the magnet 92 and the side of the outlet 5 closer to the outlet 3. That is, reducing the distance that the abutment plate 91 pushes the opening and closing plate 6 to move, so that less disinfectant falls into the collection box 8. This makes it easier to adjust the amount of disinfectant added according to the amount of rainwater in the well 1, so as to reduce waste.

[0048] Reference Figure 2 and Figure 5 A stirring shaft 16 is rotatably installed inside the well shaft 1. The rotation axis of the stirring shaft 16 is perpendicular to the sliding direction of the float 11 and parallel to the rotation axis of the first impeller 101. The stirring shaft 16 is located on the side of the float 11 near the inlet 2. A stirring blade 17 is fixedly connected to the stirring shaft 16. A rotating component 18 for driving the stirring shaft 16 to rotate is installed inside the well shaft 1. The rotating component 18 includes a second impeller 181 rotatably installed on the inner wall of the inlet 2, a rotating rod 182 coaxially connected to the second impeller 181, a second pulley 183 sleeved on the rotating rod 182 and the stirring shaft 16, and a second belt 184 wound around the second pulley 183. The rotation axis of the second impeller 181 is parallel to the rotation axis of the stirring shaft 16. The two second pulleys 183 are connected by the second belt 184.

[0049] When rainwater enters the well shaft 1 through the inlet 2, the rainwater drives the second impeller 181 to rotate. At this time, the rotation of the stirring shaft 16 is achieved through the transmission of the second pulley 183 and the second belt 184. During the rotation of the stirring blade 17 driven by the stirring shaft 16, the stirring blade 17 stirs the rainwater and disinfectant in the well shaft 1, so that the rainwater and disinfectant are fully mixed, which helps to improve the disinfection effect.

[0050] The implementation principle of this application embodiment is as follows: When it rains, rainwater enters the well shaft 1 from the inlet 2. Initially, the rainwater is discharged through the diversion outlet, and then the diversion outlet is closed. The rainwater entering from the inlet 2 drives the second impeller 181 to rotate, and through the transmission of the second pulley 183 and the second belt 184, the stirring shaft 16 drives the stirring blade 17 to rotate. When the water level in the well shaft 1 is higher than the position of the baffle 21, the rainwater flows out from the outlet 3 through the water-passing perforated plate 22. At the same time, the rainwater drives the float 11 and the counterweight 33 to move upward. At this time, the rack 123 moves upward, driving the gear 12 2. Rotation of screw 121 causes the fixed rod 13 to slide magnet 92 toward the direction closer to water inlet 2, increasing the horizontal distance from the side of medicine outlet 5 near water outlet 3 to magnet 92; rainwater at water outlet 3 drives the first impeller 101 to rotate, the first impeller 101 drives the rotating shaft 14 to rotate, and then through the transmission of the first pulley 1021 and the first belt 1022, the connecting rod 15 drives the transmission roller 71 to rotate, thereby causing the chain 73 to drive the medicine box 8 toward the direction closer to water inlet 2.

[0051] When the receiving box 8 moves the abutment plate 91 to the side of the opening and closing plate 6 near the outlet 3, the side of the abutment plate 91 away from the receiving box 8 abuts against the opening and closing plate 6, pushing the opening and closing plate 6 to slide towards the inlet 2, gradually opening the outlet 5. At this time, the disinfectant in the storage tank 4 falls into the receiving box 8. When the chain 73 moves the receiving box 8 and the abutment plate 91 to the magnet 92, the magnet 92 attracts the iron block 93, causing the iron block 93 to move the abutment plate 91 towards the chain 73, compressing the spring 941, separating the abutment plate 91 from the opening and closing plate 6. Then, the tension spring 951 pulls the opening and closing plate 6 to slide towards the outlet 3, sealing the outlet 5. Close; then, as the chain 73 continues to drive, it causes the iron block 93 and magnet 92 on the abutment plate 91 to disengage. At this time, the spring 941 pushes the abutment plate 91 to slide away from the chain 73 to reset. When the chain 73 drives the medicine receiving box 8 containing disinfectant to the transmission roller 71 near the water inlet 2, the medicine receiving box 8 tilts, and the disinfectant in the medicine receiving box 8 falls into the well shaft 1. The stirring shaft 16 drives the stirring blade 17 to stir the rainwater and disinfectant evenly, thereby disinfecting the rainwater in the well shaft 1. After disinfection, the rainwater enters the sedimentation tank 23 through the water perforated plate 22 and the water outlet 3 for sedimentation, and then flows out from the water outlet pipe 24 for collection.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
