Description

Technical Field

[0001] The present invention relates to the technical field of rainwater recycling, and in particular to an underground rainwater collection and utilization device. Background Art

[0002] Rainwater recycling is an effective way of water resource management, which involves multiple links such as rainwater collection, storage, treatment and reuse. Generally, rainwater recycling is mainly used for green irrigation, industrial water and flushing toilets in daily life.

[0003] The most commonly used existing rainwater collection device is to bury a rainwater collection box underground, and rely on a sewer well to connect the rainwater collection box, so that the rainwater can be drained into the rainwater collection box through the sewer well. During the introduction process, the rainwater entering the collection box is filtered by the set filtering component, and finally the rainwater in the collection box is pumped out by a water pump and transported to the corresponding location for use.

[0004] The shortcomings of the existing rainwater collection device are: although the existing rainwater collection device can be directly set up underground and collect water at any time when it rains, and can rely on the filter components set on the pipeline to filter impurities, the newly collected rainwater generally contains acidic gases, tail gas and some tiny impurities that are not easy to filter, and it needs to be placed for a period of time to reduce the content of these gases and allow the impurities to settle before it can be used. After collecting rainwater, the existing underground rainwater collection device is not convenient for standing the rainwater for treatment, because sometimes after the rain stops for a period of time, it will rain again, and new rainwater will enter the collection device, causing the rainwater that has been stood and settled to be polluted again, thus affecting its use. In addition, the existing rainwater collection device is not convenient for treating the sediment in the rainwater storage process. When the water pump is pumping rainwater for use, it is easy to pump away the sediment together, thereby reducing the quality of rainwater recycling. Summary of the Invention

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention collects rainwater through a rainwater well and introduces it into the water cavity of the underground collection box. After the rain stops and the rainwater has been standing for a period of time, the rotating partition plate arranged in the water cavity can be controlled to deflect to a horizontal position.

[0037] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1-12As shown, an underground rainwater collection and utilization device includes a rainwater well 1, a collection box 2 and a return water pump 9. The rainwater well 1 and the collection box 2 are both buried underground, and the wellhead of the rainwater well 1 is equipped with a manhole cover and exposed on the surface to facilitate rainwater to enter the rainwater well 1 and realize drainage and collection of rainwater. The collection box 2 is used to store rainwater introduced into the rainwater well 1; the return water pump 9 is used to pump the collected rainwater stored in the collection box 2 and transport it to the point where it needs to be utilized through the delivery pipe 4 to realize rainwater recycling. The device also includes a storage chamber, a bottom valve mechanism and a separation and sealing mechanism. The storage chamber includes a water chamber 7 and a cache chamber 6. The water chamber 7 and the cache chamber 6 are both arranged in the collection box 2, and a partition is passed between the two. Separated, a connecting hole 15 is provided between the water chamber 7 and the buffer chamber 6, and the bottom of the buffer chamber 6 is higher than the bottom of the water chamber 7 and flush with the connecting hole 15. The connecting hole 15 is at the middle height of the water chamber 7. It should be noted that the height position of the connecting hole 15 is the highest water level stored in the water chamber 7. A sliding closing valve mechanism is provided at the connecting hole 15. The return water pump 9 is provided in the water chamber 7. A switching valve mechanism is installed on the outer wall of the collection box 2. The water chamber 7 and the buffer chamber 6 are both connected to the rainwater well 1 through the switching valve mechanism. The switching valve mechanism is used to make the water chamber 7 and the buffer chamber 6 alternately connected to the rainwater well 1, so that the rainwater drained from the rainwater well 1 can enter the water chamber 7 or the buffer chamber 6;

[0039] The bottom valve mechanism is provided at the bottom of the collection box 2. The bottom valve mechanism is used to control the opening or closing of the bottom of the water chamber 7 and the buffer chamber 6; it is convenient for the discharge of the dirt settled at the bottom to avoid affecting the effect of rainwater recycling;

[0040] The partitioning and blocking mechanism includes a rotating partition plate 18, which is rotatably arranged on one side of the water chamber 7. When the rotating partition plate 18 is in a vertical position, the conversion valve mechanism connects the rainwater well 1 and the water chamber 7, which facilitates the rainwater collected during rain to enter the water chamber 7 for storage directly. When the rotating partition plate 18 is rotated to a horizontal position, the water chamber 7 is divided into a bottom space and an upper space. A transmission mechanism is provided on the rotating partition plate 18. When the rotating partition plate 18 rotates to a horizontal position, the transmission mechanism is used to open the bottom valve mechanism, and the transmission mechanism also drives the sliding closing valve mechanism to block the connecting hole 15 and make The conversion valve mechanism is used to connect the rainwater well 1 and the cache chamber 6, so that the water with precipitated pollutants at the bottom of the water chamber 7 can be discharged, leaving only the relatively clean rainwater in the upper space, which is convenient for reuse, and the cache chamber 6 is not connected with the water chamber 7 at this time. Since the cache chamber 6 is connected with the rainwater well 1 through the conversion valve mechanism at this time, the rainwater collected during the next rain can directly enter the cache chamber 6 for temporary storage, avoiding the precipitation of rainwater in the water chamber 7 before it is used up and mixed with new rainwater, which is polluted again and needs to be re-precipitated before it can be used, which will affect the overall recycling effect of rainwater.

[0041] In some embodiments, combined Figure 2 and Figure 3 As shown, the separation and sealing mechanism also includes a rotary drive mechanism and a separation frame 10. The separation frame 10 is fixedly connected to the water chamber 7 near the bottom. The rotary partition plate 18 cooperates with the separation frame 10, and the rotary partition plate 18 is rotatably connected to the side of the separation frame 10 near the cache chamber 6 through the rotary drive mechanism. The width of the rotary partition plate 18 is slightly smaller than the internal size of the water chamber 7. The rotary drive mechanism drives the rotary partition plate 18 to rotate clockwise to a horizontal position, and covers and docks with the separation frame 10, and is combined with the separation frame 10 to form a sealed separation plate body. In order to ensure the sealing performance, a sealing gasket 22 can be installed on the rotary partition plate 18. In addition, it should be noted that the return water pump 9 can be fixedly installed on the upper surface of one side of the partition frame 10, and in order to avoid the return water pump 9 interfering with the rotation of the rotating partition plate 18, a notch 11 can be dug out at the corresponding position of the rotating partition plate 18. The notch 11 facilitates the return water pump 9 to pass through the rotating partition plate 18, and a plate that can be spliced at the position of the notch 11 is set at the bottom of the position where the return water pump 9 is located, ensuring that the sealing can still be guaranteed after the rotating partition plate 18 is rotated to a horizontal position.

[0042] Among them, combined Figures 8 to 10 As shown, the above-mentioned rotation drive mechanism includes a servo motor 28 and a connecting shaft 37. The connecting shaft 37 is rotatably connected to one side of the partition frame 10, and one side of the rotating partition plate 18 is fixedly connected to the connecting shaft 37. One end of the connecting shaft 37 is provided with a steering bevel gear set that cooperates with the main shaft end of the servo motor 28.

[0043] In addition, the above-mentioned steering bevel gear group includes a first steering bevel gear 27, a second steering bevel gear 26 and a third steering bevel gear 29. The first steering bevel gear 27 is coaxially fixedly connected to one end of the connecting shaft 37, and the second steering bevel gear 26 is meshed with one side of the first steering bevel gear 27. A mounting groove 31 is opened in the partition between the water chamber 7 and the cache chamber 6. The servo motor 28 is fixedly installed in the mounting groove 31. The main shaft end of the servo motor 28 is fixedly connected to the fourth steering bevel gear 30. One side of the fourth steering bevel gear 30 is meshed with the third steering bevel gear 29, that is, the third steering bevel gear 29 is also in the mounting groove 31, and is rotatably connected to the inner wall of the mounting groove 31 through the rotating shaft. The third steering bevel gear 29 is coaxially connected to the second steering bevel gear 26.

[0044] The servo motor 28 drives the fourth steering bevel gear 30 to rotate, and the fourth steering bevel gear 30 drives the third steering bevel gear 29 to rotate. Then the third steering bevel gear 29 and the second steering bevel gear 26 rotate coaxially, and the second steering bevel gear 26 drives the meshed first steering bevel gear 27 to rotate, thereby rotating the connecting shaft 37 and realizing the rotation of the rotating partition plate 18.

[0045] It should be noted that an electronic liquid level meter 39 is provided inside the water chamber 7 for controlling the rotation of the rotary drive mechanism. The electronic liquid level meter 39 is used to detect the water level inside the water chamber 7. When the water usage in the water chamber 7 is lower than the set value, the electronic liquid level meter 39 detects that the corresponding water level value is lower than the set threshold, and relies on the matching data acquisition module to collect the corresponding liquid level data, and then performs logical judgment through the control system, and then issues a control instruction based on the judgment result to control the operation of the rotary drive mechanism, driving the rotary partition plate 18 to rotate and reset, so as to facilitate the collection and utilization of rainwater again.

[0046] In some embodiments, combined Figure 6 and Figure 7 As shown, the transmission mechanism includes a boss 20 and a traction rope 17, and the sliding closing valve mechanism is longitudinally slidingly arranged on the side of the connecting hole 15 close to the water chamber 7, one end of the traction rope 17 is connected to one side of the rotating partition plate 18, and the other end is connected to the top of the sliding closing valve mechanism, and a steering fixed pulley 25 cooperating with the traction rope 17 is arranged above the sliding closing valve mechanism, the boss 20 is fixedly connected to the other side of the rotating partition plate 18, and the bottom valve mechanism is horizontally slidingly arranged at the bottom of the collecting box 2, and a first sewage pipe 12 connected to the water chamber 7 is provided on one side of the bottom of the collecting box 2, and a second sewage pipe 13 connected to the cache chamber 6 is provided on the other side, and the first sewage pipe 12 and the second sewage pipe 13 are connected to a main sewage pipe 5 together. When the rotating partition plate 18 rotates to a horizontal position, the boss 20 pushes the bottom valve mechanism, so that the bottom valve mechanism slides horizontally to open the first sewage pipe 12 and close the second sewage pipe 13.

[0047] Among them, the bottom valve mechanism includes a first blocking block 36 and a second blocking block 14, and a first connecting groove 21 is opened at the inner bottom of the water chamber 7. The first blocking block 36 is slidably connected to the first connecting groove 21, and a compressible first connecting spring is connected between the first blocking block 36 and the first connecting groove 21. It should be noted that the upper surface of the first blocking block 36 is raised and cylindrical, which is convenient for being squeezed by the convex column 20. The second blocking block 14 is slidably set at the port of the second sewage pipe 13, and a linkage rod 23 is fixedly connected between the second blocking block 14 and the first blocking block 36. When the first connecting spring is in its original state, the first blocking block 36 blocks the port of the first sewage pipe 12 connected to the water chamber 7, and the second blocking block 14 deviates from the port of the second sewage pipe 13.

[0048] When the rotating partition plate 18 rotates clockwise to the horizontal position, the rotating partition plate 18 is pulled by the traction rope 17 to slide the sliding closing valve mechanism upward and gradually close the connecting hole 15. When the sliding closing valve mechanism slides to the limit position of its stroke and is blocked, the rotating partition plate 18 is still rotating. It should be noted that the traction rope 17 is an elastic rope. At this time, since the sliding closing valve mechanism is limited, the traction rope 17 itself is stretched under the action of the pulling force to avoid hindering the rotation of the rotating partition plate 18. At the same time, it can also keep the sliding closing valve mechanism in the position of blocking the connecting hole 15. It should be noted that when the traction rope 17 starts to pull the sliding closing valve mechanism to slide, the traction rope 17 has not yet completely undergone stretching deformation, and can overcome the weight of the sliding valve mechanism to pull it up; when the rotating partition plate 18 is about to dock with the partition frame 10, the boss 20 begins to contact and squeeze the first blocking block 36. During the rotation process, the boss 20 is The lateral thrust makes it easier to push the first blocking block 36 to slide horizontally along the first connecting slide groove 21 and compress the first connecting spring. After the rotating partition plate 18 is docked with the partition frame 10, so that the water chamber 7 is divided into the bottom space and the upper space, the top port of the first sewage pipe 12 is just opened. At this time, the sediment in the bottom space of the water chamber 7 is discharged through the first sewage pipe 12 along with part of the water, avoiding the return water pump 9 from sucking in the sediment during suction, affecting the quality of rainwater recycling. When the first blocking block 36 slides horizontally to open the top opening of the first sewage pipe 12, the first blocking block 36 drives the second blocking block 14 to slide horizontally through the linkage rod 23, blocking the top opening of the second sewage pipe 13. In this way, the buffer chamber 6 and the water chamber 7 are separated, making it convenient to use the rainwater that has been settled. The rainwater recovered during this period is temporarily stored through the buffer chamber 6 to avoid entering the water chamber 7 and affecting the previously collected rainwater.

[0049] In some specific embodiments, the sliding closing valve mechanism includes a connecting guide rail 24 and a sliding valve plate 16. The connecting guide rail 24 is fixedly connected to the inner wall of the water chamber 7, and there are two connecting guide rails 24, which are distributed on both sides of the connecting hole 15. The sliding valve plate 16 is slidingly connected to the connecting guide rail 24, and the sliding valve plate 16 is connected to the traction rope 17. An elastic sealing gasket is distributed on the side of the sliding valve plate 16 close to the connecting hole 15. When pulled by the traction rope 17, the sliding valve plate 16 slides upward along the connecting guide rail 24 to facilitate closing the connecting hole 15. When the traction rope 17 is loose, the sliding valve plate 16 can slide down and out of the connecting hole 15 by its own gravity.

[0050] In some embodiments, combined Figure 11 and Figure 12As shown, the conversion valve mechanism includes a U-shaped connecting tube 3 and a sliding valve core. The U-shaped connecting tube 3 is fixedly arranged on the outer wall of the collection box 2, and one end is connected to the cache chamber 6, and the other end is connected to the water chamber 7. The U-shaped connecting tube 3 is also connected to the bottom of the rainwater well 1 through a pipeline. The sliding valve core is arranged in the U-shaped connecting tube 3, and the sliding valve core cooperates with the rotating partition plate 18.

[0051] Among them, the sliding valve core includes a third blocking block 19, a blocking ball 32 and a traction wire 33. A second connecting groove 35 is opened on the inner wall of the water chamber 7, and near the port position where the U-shaped connecting pipe 3 is connected to the water chamber 7, the third blocking block 19 is slidably connected to the second connecting groove 35, and a compressible second connecting spring is connected between the third blocking block 19 and the second connecting groove 35. At this time, the U-shaped connecting pipe 3 and the water chamber 7 are in a connected state, and the blocking ball 32 is cooperatively arranged at the port where the U-shaped connecting pipe 3 is connected to the cache chamber 6, and the blocking ball 32 and the third blocking block 19 are connected by a traction wire 33. A fixed pulley group 34 that is coordinated with the traction wire 33 is distributed on the inner wall of the U-shaped connecting pipe 3.

[0052] When the rotating partition plate 18 is in the vertical position, the third blocking block 19 is between the rotating partition plate 18 and the inner wall of the water chamber 7, and the second connecting spring is in a compressed state. At this time, the traction wire 33 is pulled, thereby pulling the blocking ball 32 to resist the connecting port between the U-shaped connecting pipe 3 and the buffer chamber 6, thereby ensuring that the incoming rainwater can only enter the water chamber 7. When the rainwater stored in the water chamber 7 reaches a certain amount, the rotating partition plate 18 deflects from the vertical position to the horizontal position. At this time, the rotating partition plate 18 is separated from the third blocking block 19, and the third blocking block 19 slides along the second connecting groove 35 close to the U-shaped connecting pipe 3 under the action of the rebound force of the second connecting spring and the gravity of the blocking ball 32. The connecting port between the U-shaped connecting pipe 3 and the water chamber 7 is finally blocked. During this process, since the third blocking block 19 is close to the port of the U-shaped connecting pipe 3, the traction wire 33 is relaxed, which facilitates the blocking ball 32 at the other end of the U-shaped connecting pipe 3 to fall out of the port, thereby realizing the connection between the U-shaped connecting pipe 3 and the cache chamber 6, and facilitating the flow and storage of rainwater into the cache chamber 6. When the rotating partition plate 18 rotates to the vertical position, its edge squeezes and pushes the third blocking block 19, pushing it to slide along the second connecting slot 35 out of the corresponding port of the U-shaped connecting pipe 3. During this process, the third blocking block 19 pulls the traction wire 33, thereby pulling the blocking ball 32 to block the corresponding port of the U-shaped connecting pipe 3.

[0053] It should be noted that the third blocking block 19 can be a T-shaped block, so that the edge of the rotating partition plate 18 can be used to push the third blocking block 19 .

[0054] In some specific embodiments, a sedimentation tank 8 is provided at the inner bottom of the cache chamber 6, and the position of the sedimentation tank 8 is lower than the position of the connecting hole 15. The sedimentation tank 8 is also connected to the second sewage pipe 13, so that the rainwater temporarily stored in the cache chamber 6 can be discharged through the second sewage pipe 13 to avoid the initial rainwater or sediment that falls into the bottom sedimentation tank 8 from flowing into the water chamber 7.

[0055] In some specific embodiments, in order to facilitate the effective control of rainwater recycling, the device includes a main recycling control system, which includes a rainwater detection unit, a timing module 1, a timing module 2, a timing module 3, a control module and a drive module. The rainwater detection unit can be used to detect whether rainwater has passed through the rainwater well 1. If so, the control module resets the timing of the timing module 1 to zero, otherwise, the control module starts timing from the beginning; when the timing of the timing module 1 reaches the set time, it means that the rain has stopped for a long time. The set time can be set based on the intermittent rain situation, for example, it can be set to two days. After the timing of the timing module 1 reaches the set time, the control module controls the timing module 2 to start timing after detecting that the timing module 1 has reached the set time. The timing process is the sedimentation time of the rainwater collected and separated in the water chamber 7, and the water delivery end of the return water pump 9 is installed with a solenoid valve. The control module can control the opening and closing of the solenoid valve. During the timing process of the timing module 2, the solenoid valve is in a closed state to prevent the rainwater that has not been settled and settled from being used. When the timing of the timing module 2 reaches the set time, it means that the rainwater collected and separated in the water chamber 7 has been settled for the set time. Then the control module detects that the timing module 2 reaches the set time threshold, and controls the solenoid valve to open, and sends a control instruction to the drive module. The drive module starts the rotary drive mechanism, so that the rotary drive mechanism drives the rotary partition plate 18 to rotate clockwise to a horizontal position, so that the connecting hole 15 between the buffer chamber 6 and the water chamber 7 is closed, and the sediment at the bottom of the water chamber 7 is discharged.

[0056] It should be noted that the water chamber 7 can be vented by connecting to the external environment near the top, so that the harmful gases emitted by the rainwater in the water chamber 7 during the period of settling and standing can be discharged.

[0057] In addition, an electric-controlled valve 38 is installed on the rotating partition plate 18. After the timing module 2 reaches the set time, the control module starts to start the timing module 3. The timing process is the shelf life of the rainwater after sedimentation and static. After the timing module 3 reaches the set time, the control module monitors that the timing module 3 has reached the set time, and sends a control instruction to control the electric-controlled valve 38 to open, so that the deteriorated rainwater can pass through the electric-controlled valve 38 from the upper space of the water chamber 7 to enter the lower space. Since the first sewage pipe 12 is in an open state at this time, it is convenient to discharge the deteriorated rainwater, and when the water level drops below the set value, the electronic liquid level meter 39 detects feedback, so that the rotary drive mechanism drives the rotating partition plate 18 to rotate and reset, so as to facilitate the collection and utilization of rainwater again.

[0058] It should be noted that when rainwater is stored in the buffer chamber 6, another set of auxiliary recovery control systems can also be used to monitor the static sedimentation of the temporarily stored rainwater. After the rainwater in the water chamber 7 is discharged and the connecting hole 15 is blocked, the corresponding main recovery control system will feedback a signal to the auxiliary recovery control system, so that the auxiliary recovery control system performs rain monitoring. During this time period, if it rains, the auxiliary recovery control system will perform timing monitoring on the rainwater entering the buffer chamber 6 according to the process of the main control system monitoring the rainwater in the water chamber 7, but will not feedback control the operation of the rotary drive mechanism. After the timing of the timing module 2 reaches the set time, it will directly enter the timing module 3 timing the warranty time, that is, the auxiliary recovery control system will start to monitor the rain. The control system also includes another set of timing module 1, timing module 2, timing module 3 and control module, but does not include a drive module, and when the connecting hole 15 is opened, the rainwater in the buffer chamber 6 enters the water chamber 7, and at this time the main control system synchronously collects the duration data of the timing module 3 of the auxiliary recovery control system and inputs it into the timing module 3 in the main control system, that is, the timing module 3 of the main control system continues to time according to the time reached by the timing module 3 of the auxiliary recovery control system. If the timing reaches the warranty time, an alarm is directly issued to the background, and a remote control valve can also be installed at the bottom of the water chamber 7, which can be opened by manual remote operation to discharge the water.

[0059] It should be noted that, in the above solution, the pipe connecting the rainwater well 1 and the collection box 2 can be equipped with a filter assembly to filter out some large debris and avoid pipe blockage.

[0060] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios:

[0061] When it rains, rainwater is drained through the rainwater well 1 and enters the water chamber 7 through the open side of the U-shaped connecting pipe 3. When the rain stops, the rainwater in the water chamber 7 is allowed to settle for a period of time, which facilitates the precipitation of impurities in the rainwater to the bottom and the discharge of harmful gases mixed in the rainwater, such as acidic gases, tail gas, etc. During this process, the solenoid valve provided at the water delivery end of the return water pump 9 can be kept in a closed state. When the set set time is reached, the solenoid valve is opened by the control module of the control system, and the servo motor 28 is controlled to operate. The servo motor 28 drives the fourth steering bevel gear 30 to rotate, and the fourth steering bevel gear 30 drives the third steering bevel gear 29 to rotate. Then, the third steering bevel gear 29 and the second steering bevel gear 26 rotate coaxially, and the second steering bevel gear 26 drives the meshed first steering bevel gear 27 to rotate, thereby causing the connecting shaft 37 to rotate clockwise, and the rotating partition plate 18 rotates accordingly.

[0062] When the rotating partition plate 18 rotates clockwise to a horizontal position, it covers and docks onto the partition frame 10, and is combined with the partition frame 10 to form a sealed partition plate body, which divides the water cavity 7 into an upper space and a bottom space. When the swivel plate 18 is in the process of rotating clockwise to the horizontal position, the swivel plate 18 is pulled by the traction rope 17 to slide the sliding valve plate 16 upward along the connecting guide rail 24, so as to close the connecting hole 15. When the sliding valve plate 16 reaches the limit position of its stroke, it is blocked. At this time, the swivel plate 18 is still rotating. It should be noted that the traction rope 17 is an elastic rope. Since the sliding valve plate 16 is limited, the traction rope 17 itself is stretched under the action of the pulling force to avoid hindering the rotation of the swivel plate 18. At the same time, it can also keep the sliding valve plate 16 in the position of blocking the connecting hole 15. It should be noted that when the traction rope 17 starts to pull the sliding valve plate 16 to slide, the traction rope 17 has not yet completely stretched and deformed, and can overcome the weight of the sliding valve plate 16 and pull it up. When the swivel plate 18 is about to dock with the partition frame 10, the boss 20 starts The first sealing block 36 is contacted and squeezed, and the convex column 20 has a lateral thrust during the rotation process, thereby facilitating the first sealing block 36 to slide horizontally along the first connecting slide groove 21 and compressing the first connecting spring. After the rotating partition plate 18 is docked with the partition frame 10, so that the water chamber 7 is divided into the bottom space and the upper space, the top port of the first sewage pipe 12 is just opened. At this time, the sediment in the bottom space of the water chamber 7 is discharged through the first sewage pipe 12 along with part of the water, avoiding the sediment being sucked into the return water pump 9 during suction, which affects the quality of rainwater recycling. When the first sealing block 36 slides horizontally to open the top opening of the first sewage pipe 12, the first sealing block 36 drives the second sealing block 14 to slide horizontally through the linkage rod 23, blocking the top opening of the second sewage pipe 13. In this way, the buffer chamber 6 and the water chamber 7 are separated, making it convenient to use the rainwater that has been settled.

[0063] The rotating partition plate 18 deflects from the vertical position to the horizontal position, and at this time the rotating partition plate 18 disengages from the third blocking block 19. The third blocking block 19 slides along the second connecting groove 35 under the action of the rebound force of the second connecting spring and the gravity of the blocking ball 32, close to the connecting port between the U-shaped connecting pipe 3 and the water chamber 7, and finally blocks it. In this process, since the third blocking block 19 is close to the port of the U-shaped connecting pipe 3, the traction wire 33 is relaxed, which facilitates the blocking ball 32 at the other end of the U-shaped connecting pipe 3 to fall and disengage from the port, thereby realizing the connection between the U-shaped connecting pipe 3 and the cache chamber 6, facilitating the flow and storage of rainwater into the cache chamber 6, and avoiding entering the water chamber 7 to affect the quality of the rainwater collected before.

[0064] When the rainwater in the water chamber 7 is used up, the electronic liquid level meter 39 detects that the liquid level is lower than the set value, and relies on the main control system to feedback control the servo motor 28 of the rotary drive mechanism to drive the rotating partition plate 18 to rotate and reset. At this time, the connecting hole 15 between the buffer chamber 6 and the water chamber 7 is opened, which facilitates the rainwater temporarily stored in the buffer chamber 6 to pass into the water chamber 7, so as to facilitate subsequent reuse.

[0065] The above describes several embodiments of the present invention in detail, but the embodiments of the present invention are not limited to these and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
