Description

Technical Field

[0001] This invention relates to the field of farmland water conservancy engineering technology, specifically to a multifunctional rainwater collection cellar. Background Technology

[0002] Currently, water conservancy is an important project in agricultural planting. In some agricultural areas with little rainfall, water storage ponds or rainwater collection pits are generally used to collect rainwater during the rainy season and then use it during droughts. Because rainwater in water storage ponds evaporates quickly, rainwater collection pits are gradually being promoted and used.

[0003] The existing multifunctional rainwater collection silos generally include a rainwater collection silo body and an arched plate. A water collection hopper is inserted into the interior of the top of the rainwater collection silo body, and supports are fixedly installed at the bottom of both sides of the outer wall of the rainwater collection silo body. A drive motor is fixedly installed at the bottom of the rainwater collection silo body.

[0004] The aforementioned rainwater collection cistern can filter rainwater and clean sediment inside the cistern, but it still has the following drawbacks: when using a water pipe to pump water, it is always easy to draw out the turbid water from the lower layer, and the debris filtered down from the arched plate will clog the filter holes, affecting the continuous flow of rainwater into the rainwater collection cistern. Summary of the Invention

[0005] The technical problem this invention aims to solve is to overcome the shortcomings of existing systems and provide a multifunctional rainwater collection cistern. This cistern employs a clean water extraction position control mechanism and a multifunctional clean water extraction mechanism, ensuring that clean water is always extracted from the upper layer during pumping, avoiding the use of turbid water from the lower layer and preventing turbid water from clogging the pipes. The collected rainwater undergoes two filtrations, resulting in excellent filtration efficiency. Furthermore, it allows for the cleaning of debris left on the filter screen, reducing the frequency of manual intervention due to filter clogging. This ensures a continuous and stable collection of filtered rainwater. A single set of pipes located inside the rainwater cistern can pump water and remove sludge, eliminating the need for external sludge pipes. The pipe layout is simple and convenient, effectively solving the problems described in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional rainwater collection cistern, comprising a rainwater cistern body, wherein the rainwater cistern body has a spherical structure, and further comprising:

[0007] The rainwater cellar water inlet mechanism includes an inlet cylinder, an overflow annular trough, and an overflow channel. The bottom end of the inlet cylinder is fixedly connected to the round opening at the top of the rainwater cellar. The overflow annular trough is fixedly connected to the outer periphery of the bottom of the inlet cylinder. The top horizontal position of the inlet cylinder is higher than the bottom horizontal position of the overflow annular trough. Multiple overflow channels are arranged in a ring array at the top of the overflow annular trough.

[0008] The mud and water extraction mechanism includes an installation rod, a waterproof bearing, a common extraction vertical pipe, a mud extraction control solenoid valve, a clean water extraction port, and a water extraction control solenoid valve. The installation rod is installed inside the water inlet cylinder. The middle of the installation rod is rotatably connected to the common extraction vertical pipe through the waterproof bearing. The center of the common extraction vertical pipe coincides with the center of the water inlet cylinder. The bottom end of the common extraction vertical pipe extends to the bottom of the rainwater cellar. The mud extraction control solenoid valve is installed at the bottom of the common extraction vertical pipe. Four clean water extraction ports are arranged in a circular array above the mud extraction control solenoid valve. Each clean water extraction port is equipped with a water extraction control solenoid valve.

[0009] The clean water extraction position control mechanism is vertically slidably installed on the common extraction vertical pipe, and the clean water extraction position control mechanism is connected to two clean water extraction ports.

[0010] The rainwater silo, inlet cylinder, and overflow annular trough are buried in the soil layer of the low-lying area. The bottom of the overflow trough is flush with the soil surface. The specific number of overflow troughs is selected according to needs. For ease of installation, the rainwater silo can be divided into upper and lower halves, connected by interlocking connecting rings and grooves to form a stable and sealed rainwater silo. After rain, rainwater collects in the low-lying area and then flows into the overflow annular trough through the overflow trough. Large debris, such as leaves, cannot pass through the overflow trough and is blocked on the outside of the overflow annular trough. Rainwater overflows the top of the inlet cylinder and enters the inlet cylinder, then collects in the rainwater silo through the round opening at the top of the silo. After a period of sedimentation, the sediment in the rainwater forms sludge at the bottom of the silo. The four pumping control solenoid valves are then closed. Open the sludge removal control solenoid valve, and connect the sludge pump to the top of the common extraction riser. This allows the sludge at the bottom of the rainwater cisterns to be removed via the common extraction riser. Close the sludge removal control solenoid valve, and open the two clean water extraction ports connected to the two clean water extraction position control mechanisms via the water extraction control solenoid valve. The clean water pump is connected to the top of the common extraction riser and operates. The clean water extraction position control mechanism draws clean water from the upper layer of the rainwater cisterns. This clean water then enters the common extraction riser through the two clean water extraction ports and the two water extraction control solenoid valves, and is finally extracted and used by the clean water pump. The clean water extraction position control mechanism ensures that water from the upper layer of the rainwater cisterns can always be extracted, reducing the chance of drawing turbid rainwater and improving the cleanliness of the water used. The sludge removal control solenoid valve and the water extraction control solenoid valve allow you to choose whether to extract sludge or clean water.

[0011] Furthermore, the water inlet mechanism of the cellar also includes an overflow channel cleaning component. The overflow channel cleaning component is installed on the top of the overflow annular channel and can clean the leaves and other debris blocking the outer end of the overflow channel.

[0012] Furthermore, it also includes a primary rainwater filtration mechanism, which comprises an annular cleaning tank, an annular filter screen, and sand-blocking rings. The annular cleaning tank is disposed within the overflow annular tank, and an annular filter screen is disposed on the top outer side of the annular cleaning tank. The top surface of the annular filter screen is flush with the top surface of the overflow annular tank. The top inner surface of the annular cleaning tank is flush with the top surface of the inlet cylinder. Multiple sand-blocking rings are disposed on the bottom inner surface of the annular cleaning tank. There can be three sand-blocking rings, and the three sand-blocking rings, the annular cleaning tank, and the inlet cylinder are arranged concentrically. Rainwater flowing through the overflow channel passes through the filter holes on the annular filter screen. Some small debris in the rainwater is filtered by the annular filter screen. The filtered rainwater falls to the bottom of the annular cleaning tank. Sand carried in the rainwater is blocked by the sand-blocking ring and remains at the bottom of the annular cleaning tank. The rainwater in the annular cleaning tank overflows the inner top surface of the annular cleaning tank and the top surface of the inlet cylinder, and then enters the inlet cylinder.

[0013] Furthermore, it also includes a lifting control mechanism, which comprises a lifting platform and a lifting assembly. The lifting platform is mounted on the outer side of the overflow annular trough via the lifting assembly, and the lifting platform is located above the center of the overflow annular trough. The lifting assembly is used to control the lifting of the lifting platform, thereby controlling the up-and-down movement of the components mounted on the lifting platform.

[0014] Furthermore, the mud and water extraction mechanism also includes a pipe joint, a rotating pipe, a rotary joint, a selection solenoid valve, a T-shaped tee joint, a clean water extraction component, and a sludge extraction component. A vertical rotating pipe is inserted into the circular hole in the middle of the lifting platform. A pipe joint is provided at the bottom end of the rotating pipe. The pipe joint and the extraction share a vertical pipe and are arranged vertically and vertically. The top end of the rotating pipe is connected to the bottom end of the T-shaped tee joint through the rotary joint. The top left end of the T-shaped tee joint is connected to the sludge extraction component, and the top right end of the T-shaped tee joint is connected to the clean water extraction component. Two selection solenoid valves are respectively installed on the top left and right ends of the T-shaped tee joint.

[0015] Furthermore, it also includes a sludge scraping mechanism, which includes a support bearing, connecting rods and sludge scrapers. The rotating pipe is rotatably installed in the circular hole in the middle of the lifting platform through the support bearing. The support bearing is a tapered roller bearing. The top of the rotating pipe is connected to a rotating power assembly. The bottom of the extraction common vertical pipe is equipped with a sludge suction hood. The left and right sides of the sludge suction hood are respectively connected to two sludge scrapers through two connecting rods.

[0016] Furthermore, the clean water extraction position control mechanism includes a slip ring, a float plate, spokes, a fixed ring, a water inlet 1, and a water suction hose 1. A slip ring is vertically slidably installed on the common extraction vertical pipe, and a float plate is installed on the outer periphery of the slip ring. The bottom front and rear sides of the slip ring are respectively connected to two fixed rings through two spokes. Two water inlets 1 are detachably installed in the two fixed rings, and the two water inlets 1 are set downwards. The tops of the two water inlets 1 are respectively connected to two clean water extraction ports through two water suction hoses 1.

[0017] Furthermore, it also includes a multi-functional clean water extraction mechanism, which comprises a movable shaft, a swing arm, two water suction hoses, two water intake ports, and a floating water box. The middle of the common extraction vertical pipe is movably connected to one end of the two swing arms through a longitudinal movable shaft. The movable shaft is located at the center of the rainwater cellar. Two water intake ports are detachably installed in the middle of the two swing arms, with the two water intake ports facing downwards. The tops of the two water intake ports are connected to two clean water extraction ports through two water suction hoses. Two installation slots are opened at the ends of the two swing arms away from the movable shaft, and two floating water boxes are installed in the two installation slots respectively.

[0018] Furthermore, the multifunctional clean water extraction mechanism also includes arc-shaped baffles, bolts, and cleaning plates for the inner wall of the rainwater cellar. Two cleaning plates for the inner wall of the cellar are respectively bolted to the ends of the two swing arms away from the movable axis. An arc-shaped baffle is positioned at the bottom of each swing arm between the second water inlet and the cleaning plate. As the water level in the rainwater cellar changes, the swing arms oscillate relative to the movable axis. At this time, the cleaning plates for the inner wall of the cellar also move with the swing arms. When the swing arms move, they can scrape off the deposits on the inner wall of the rainwater cellar, thus cleaning the inner wall. The arc-shaped baffles can block the turbidity generated during cleaning, preventing debris from falling off the inner wall of the rainwater cellar from entering the second water inlet and preventing this debris from being extracted and used with the clean water.

[0019] Furthermore, it also includes a secondary rainwater filtration mechanism, which comprises a filter screen mounting ring, a conical filter screen, a filter screen insert ring, and a filter screen cleaning assembly. The top of the water inlet cylinder is equipped with a filter screen mounting ring, which is connected to the bottom of the conical filter screen. A filter screen insert ring is provided at the top center of the conical filter screen. The top of the extraction common vertical pipe passes through the filter screen insert ring, and two filter screen cleaning assemblies are respectively installed on the extraction common vertical pipe at positions above and below the filter screen insert ring.

[0020] Compared with existing technologies, the beneficial effects of this multifunctional rainwater harvesting cellar are:

[0021] 1. The floating tray floats continuously with the rainwater collected in the rainwater cellar. The buoyancy of the floating tray also causes the slip ring to slide along the common vertical pipe for extraction. The slip ring drives the movement of the first suction port through the spokes and the fixed ring. Therefore, the floating tray keeps the first suction port below the water surface. The clean water extraction port draws clean water from below the water surface through the first suction hose and the first suction port. The buoyancy of the floating tray causes the end of the swing rod away from the moving axis to swing upward as the water level in the rainwater cellar rises and downward as the water level in the rainwater cellar falls. This also keeps the second suction port below the water surface. The clean water extraction port draws clean water from below the water surface through the second suction hose and the second suction port. Therefore, the use of a clean water extraction position control mechanism and a multi-functional clean water extraction mechanism can always extract clean water from the upper layer during pumping, avoiding the use of the turbid water in the lower layer and preventing the turbid water from clogging the pipes.

[0022] 2. Rainwater flowing through the overflow trough passes through the filter holes on the annular filter screen. Small debris in the rainwater is filtered by the annular filter screen. The filtered rainwater falls to the bottom of the annular cleaning tank. Sand carried in the rainwater is blocked by the sand-blocking ring and remains at the bottom of the annular cleaning tank. The rainwater in the annular cleaning tank overflows the inner top surface of the annular cleaning tank and the top surface of the inlet cylinder, and then enters the inlet cylinder. The conical filter screen filters the water entering the inlet cylinder, and the filtered debris remains in the conical filter screen. When the shared vertical pipe is rotated at the top of the filter screen, it drives the filter screen cleaning component to rotate. When the filter screen cleaning component rotates, it brushes the upper and lower sides of the conical filter screen. The debris filtered down from the upper part of the conical filter screen falls into the annular cleaning tank, preventing the debris from quickly clogging the filter holes on the conical filter screen and avoiding the need for frequent manual cleaning of the conical filter screen. The collected rainwater is filtered twice, which has a good filtration effect on rainwater and can clean the debris left on the filter screen, reducing the frequency of manual intervention due to filter screen clogging.

[0023] 3. Close the pumping control solenoid valve and the selection solenoid valve on the right side of the T-type tee connector, and open the sludge pumping control solenoid valve and the selection solenoid valve on the left side of the T-type tee connector. This will control the sludge extraction component to work, allowing the sludge deposited at the bottom of the rainwater cellar to be extracted through the shared vertical pipe, thus cleaning the sludge in the rainwater cellar. Open the pumping control solenoid valve and the selection solenoid valve on the right side of the T-type tee connector, and close the sludge pumping control solenoid valve and the selection solenoid valve on the left side of the T-type tee connector. This will control the clean water extraction component to work, allowing water to be extracted from the rainwater cellar for use. A single pipeline located inside the rainwater cellar can be used for both pumping water and extracting sludge, eliminating the need for sludge pipes to be laid outside the rainwater cellar. The pipeline layout is simple and convenient. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1, please refer to Figures 1 to 12 This embodiment provides a multifunctional rainwater collection cistern, including a rainwater cistern body 1, which is a spherical structure, and also includes a cistern body water inlet mechanism 2, a mud and water selection and extraction mechanism 4, and a clean water extraction position control mechanism 6.

[0039] The water inlet mechanism 2 of the rainwater cellar includes an inlet cylinder 21, an overflow annular trough 22 and an overflow channel 24. The bottom end of the inlet cylinder 21 is fixedly connected to the round opening at the top of the rainwater cellar 1. The overflow annular trough 22 is fixedly connected to the outer periphery of the bottom of the inlet cylinder 21. The top horizontal position of the inlet cylinder 21 is higher than the horizontal position of the bottom of the overflow annular trough 22. Multiple overflow channels 24 are arranged in a ring array at the top of the overflow annular trough 22.

Multiple handles 27 are arranged in a circular array at the top of the rotating ring 26, and multiple overflow channel cleaning brushes 28 are arranged in a circular array at the bottom of the rotating ring 26. The bristles of the overflow channel cleaning brushes 28 face outwards from the overflow annular channel 22. The specific number of handles 27 and overflow channel cleaning brushes 28 is set as needed. The handles 27 facilitate the rotation of the rotating ring 26 relative to the top retaining ring 25, thereby allowing the multiple overflow channel cleaning brushes 28 to rotate relative to the overflow annular channel 22. The overflow channel cleaning brushes 28 clean leaves and other debris clogging the overflow channel 24, preventing the overflow channel 24 from becoming blocked and difficult to clean.

[0043] The mud and water extraction mechanism 4 includes an installation rod 41, a waterproof bearing 42, a common extraction vertical pipe 43, a mud extraction control solenoid valve 45, a clean water extraction port 46, and a water extraction control solenoid valve 47.

[0044] The clean water extraction position control mechanism 6 is vertically slidably installed on the common extraction vertical pipe 43, and the clean water extraction position control mechanism 6 is connected to two clean water extraction ports 46.

[0045] The multi-functional rainwater collection silo also includes a primary rainwater filtration mechanism 3.

[0046] Rainwater flowing through the overflow channel 24 passes through the filter holes on the annular filter screen 32. Some small debris in the rainwater is filtered by the annular filter screen 32. The filtered rainwater falls to the bottom of the annular cleaning tank shell 31. Sand carried in the rainwater is blocked by the sand-blocking ring 34 and remains at the bottom of the annular cleaning tank shell 31. The rainwater in the annular cleaning tank shell 31 overflows the inner top surface of the annular cleaning tank shell 31 and the top surface of the water inlet cylinder 21, and then enters the water inlet cylinder 21.

[0047] The primary rainwater filtration mechanism 3 also includes a second annular filter screen 33.

The bottom end of the lead screw 85 is rotatably connected to one of the ear seats 84 via a bearing. A lead screw nut 86 is embedded in the support plate 82 at the position corresponding to the lead screw 85. The lead screw nut 86 is connected to the lead screw 85. A handwheel 87 is installed at the top of the lead screw 85. By rotating the lead screw 85 clockwise with the handwheel 87, the lead screw 85 and the lead screw nut 86 cooperate to allow the support plate 82 and the lifting platform 81 to move upward along the column 83. By rotating the lead screw 85 counterclockwise with the handwheel 87, the support plate 82 and the lifting platform 81 move downward along the column 83.

[0050] The lifting assembly is used to control the lifting platform 81 to move up and down, thereby controlling the up and down movement of the components installed on the lifting platform 81.

[0051] The lifting control mechanism 8 also includes an equipment protection box 88, which is fixedly connected to the top of the lifting platform 81 by screws.

[0052] The mud and water extraction mechanism 4 also includes a pipe joint 48, a rotating pipe 49, a rotary joint 410, a selection solenoid valve 411, a T-shaped tee joint 416, a clean water extraction component, and a sludge extraction component. A vertical rotating pipe 49 is inserted into the round hole in the middle of the lifting platform 81. A pipe joint 48 is provided at the bottom end of the rotating pipe 49. The pipe joint 48 is arranged vertically and vertically with the extraction common vertical pipe 43. The top end of the rotating pipe 49 is connected to the bottom end of the T-shaped tee joint 416 through the rotary joint 410. The top left end of the T-shaped tee joint 416 is connected to the sludge extraction component, and the top right end of the T-shaped tee joint 416 is connected to the clean water extraction component. Two selection solenoid valves 411 are installed on the top left and right ends of the T-shaped tee joint 416, respectively. The equipment protection box 88 can shield and protect the rotary joint 410, the selection solenoid valve 411, the T-shaped tee joint 416, the clean water extraction component, and the sludge extraction component.

The other end of the sludge discharge pipe 415 extends to the outside of the equipment protection box 88.

[0055] The lifting assembly controls the lowering of the lifting platform 81. The lifting platform 81 drives the pipe joint 48, the rotating pipe 49, the rotary joint 410, the selection solenoid valve 411, the T-type tee joint 416, the clean water extraction assembly, and the sludge extraction assembly to descend. The bottom of the pipe joint 48 is fixedly connected to the top of the extraction common vertical pipe 43. Closing the water extraction control solenoid valve 47 and the selection solenoid valve 411 on the right end of the T-type tee joint 416, and opening the sludge extraction control solenoid valve 45 and the selection solenoid valve 411 on the left end of the T-type tee joint 416, controls the sludge extraction assembly to work, which can extract the sludge deposited at the bottom of the rainwater cellar 1 through the extraction common vertical pipe 43, thereby cleaning the sludge in the rainwater cellar 1. Open the pumping control solenoid valve 47 and the selection solenoid valve 411 on the right end of the T-type tee connector 416, and close the sludge pumping control solenoid valve 45 and the selection solenoid valve 411 on the left end of the T-type tee connector 416. This controls the operation of the clean water extraction component, allowing water to be extracted from the rainwater cellar 1 for use. Open the two pumping control solenoid valves 47 connected to the clean water extraction position control mechanism 6, and close the other two pumping control solenoid valves 47. This ensures that the clean water from the upper layer of the rainwater cellar 1 is extracted through the clean water extraction position control mechanism 6, ensuring the cleanliness of the extracted water and avoiding the extraction of turbid water from the lower layer. Disconnect the pipe connector 48 from the common extraction vertical pipe 43. The lifting component controls the lifting platform 81 to rise, allowing the pipe connector 48 to move upward and detach from the top of the common extraction vertical pipe 43. This facilitates the removal of the annular cleaning tank shell 31 from the overflow annular tank 22, making it easier to clean the sand inside the annular cleaning tank shell 31 and the clogged annular filter screen 32.

[0056] In addition, it also includes a sludge scraping mechanism 9, which includes a support bearing 91, a connecting rod 95 and a sludge scraper 96. The rotating pipe 49 is rotatably installed in the round hole in the middle of the lifting platform 81 through the support bearing 91. The support bearing 91 is a tapered roller bearing. The top of the rotating pipe 49 is connected to the rotating power component. The bottom of the extraction common vertical pipe 43 is equipped with a sludge suction cover 44. The left and right sides of the sludge suction cover 44 are respectively connected to two sludge scrapers 96 through two connecting rods 95. The equipment protection box 88 can shield and protect the rotating power component.

[0057] The rotary power assembly includes a driven gear 92, a driving gear 93, and a power motor 94. The driven gear 92 is fixedly connected to the top of the rotating tube 49, and the power motor 94 is installed on the lifting platform 81. The output shaft of the power motor 94 is fixedly connected to the driving gear 93. The driving gear 93 meshes with the driven gear 92. The power motor 94 is a servo motor. The power motor 94 drives the driving gear 93 to rotate, and drives the rotating tube 49 to rotate through the transmission of the driven gear 92.

[0058] A rotary power assembly drives the rotating pipe 49 to rotate. The rotary joint 410 ensures that the rotating pipe 49 maintains stable connection with the T-shaped tee joint 416 while rotating relative to it. The rotating pipe 49 drives the extraction common vertical pipe 43 to rotate via the pipe joint 48. The extraction common vertical pipe 43 drives the sludge scraper 96 to rotate relative to the rainwater cistern 1 via the sludge suction hood 44 and connecting rod 95. This scrapes the sludge at the bottom of the rainwater cistern 1, removing it from the inner wall of the cistern 1, making it easier to extract the sludge from the cistern 1 using the sludge suction hood 44 and the extraction common vertical pipe 43. The sludge suction hood 44 increases the extraction area of ​​the extraction common vertical pipe 43, allowing for better sludge extraction. Because the common extraction riser 43 rotates, controlling the sludge extraction control solenoid valve 45 and the water extraction control solenoid valve 47 on the common extraction riser 43 becomes complicated, as the cables connecting the sludge extraction control solenoid valve 45 and the water extraction control solenoid valve 47 will become tangled. Therefore, after the rotary power assembly controls the common extraction riser 43 to rotate clockwise once, it is necessary to control the common extraction riser 43 to rotate counterclockwise once. If the rotary power assembly needs to control the common extraction riser 43 to rotate continuously, a conductive slip ring needs to be installed on the rotating pipe 49. The conductive slip ring is connected to the sludge extraction control solenoid valve 45 and the water extraction control solenoid valve 47 through a follower cable. The follower cable connecting the sludge extraction control solenoid valve 45 and the water extraction control solenoid valve 47 can be built into a wire hole in the inner wall of the common extraction riser 43. The conductive slip ring is set using existing technology, and waterproof measures are also required.

[0059] The clean water extraction position control mechanism 6 includes a slip ring 61, a float plate 62, spokes 63, a fixed ring 65, a water inlet 66, and a water suction hose 67. The slip ring 61 is vertically slidably installed on the common extraction vertical pipe 43. The float plate 62 is installed on the outer periphery of the slip ring 61. The bottom front and rear sides of the slip ring 61 are connected to two fixed rings 65 through two spokes 63 respectively. Two water inlets 66 are detachably installed in the two fixed rings 65. The two water inlets 66 are set downwards. The tops of the two water inlets 66 are connected to two clean water extraction ports 46 through two water suction hoses 67 respectively.

[0060] The water extraction position control mechanism 6 also includes a retaining sleeve 64. Two retaining sleeves 64 are provided at the bottom of the float plate 62. The two retaining sleeves 64 are respectively connected to two spokes 63. The retaining sleeves 64 are used to connect the float plate 62 and the spokes 63, making the installation of the float plate 62 more stable.

[0061] The floating plate 62 floats continuously with the help of the rainwater collected in the rainwater cellar 1. The buoyancy of the floating plate 62 also allows the slip ring 61 to slide along the common extraction vertical pipe 43. The slip ring 61 drives the water inlet 66 to move through the spokes 63 and the fixed ring 65. Therefore, the floating plate 62 keeps the water inlet 66 below the water surface. The clean water extraction port 46 draws clean water below the water surface through the water suction hose 67 and the water inlet 66, without drawing water from the bottom of the rainwater cellar 1, thus avoiding drawing turbid water. The floating plate 62 is a hollow plate filled with air.

[0062] In use, the rainwater silo 1, the inlet cylinder 21, and the overflow annular trough 22 are buried in the soil layer of the low-lying area. The bottom of the overflow trough 24 is flush with the soil surface, and the specific number of overflow troughs 24 is selected according to the needs. To facilitate the installation of the rainwater silo 1, the rainwater silo 1 can be divided into two halves, and the two halves are connected by interlocking connecting rings and connecting grooves to form a stable and sealed rainwater silo 1. After rain, rainwater gathers in the low-lying area and then enters the overflow annular trough 22 through the overflow trough 24. Large debris such as leaves cannot pass through the overflow trough 24 and are blocked on the outside of the overflow annular trough 22. The rainwater overflows the top of the inlet cylinder 21 and enters the inlet cylinder 21. Then, it collects in the rainwater silo 1 through the round opening at the top of the rainwater silo 1. After a period of sedimentation, the sediment in the rainwater forms sludge at the bottom of the rainwater silo 1. Close the four water pumping control solenoid valves 47 and open the sludge pumping control solenoid valve 45. Connect the sludge pump to the top of the common extraction riser 43 to pump away the sludge at the bottom of the rainwater cistern 1. Close the sludge pumping control solenoid valve 45 and open the two clean water extraction ports 46 connected to the two clean water extraction position control mechanisms 6 via the water pumping control solenoid valve 47. Connect the clean water pump to the top of the common extraction riser 43 and operate. The clean water pumping position control mechanism 6 draws in the upper layer of clean water from the rainwater cistern 1. The upper layer of clean water then enters the common extraction riser 43 through the two clean water extraction ports 46 and the two water pumping control solenoid valves 47, and is finally pumped out by the clean water pump. Using the clean water extraction position control mechanism 6 ensures that the upper layer of water in the rainwater cistern 1 can always be pumped, reducing the chance of pumping turbid rainwater and improving the cleanliness of the water. The sludge pumping control solenoid valve 45 and the water pumping control solenoid valve 47 allow you to choose whether to pump sludge or clean water.

[0063] Example 2, please refer to Figures 1 to 12 This embodiment provides a technical solution: a multifunctional rainwater collection cistern. This embodiment has a roughly the same structure as Embodiment 1, the difference being:

[0064] It also includes a multi-functional clean water extraction mechanism 7, which includes a movable shaft 71, a swing rod 72, a second water suction hose 73, a second water suction port 74, and a floating water box 75. The middle part of the common extraction vertical pipe 43 is movably connected to one end of the two swing rods 72 through the longitudinal movable shaft 71. The movable shaft 71 is located at the center of the rainwater cellar 1. The middle part of the two swing rods 72 is detachably equipped with two second water suction ports 74. The two second water suction ports 74 are set downwards, and the top of the two second water suction ports 74 are respectively connected to two clean water extraction ports 46 through two second water suction hoses 73. Two installation slots are opened at the ends of the two swing rods 72 away from the movable shaft 71, and two floating water boxes 75 are installed in the two installation slots respectively.

[0065] The multi-functional clean water extraction mechanism 7 also includes an arc-shaped baffle 76, bolts 77, and a cleaning plate 78 for the inner wall of the rainwater collection cellar. Two cleaning plates 78 are installed at the ends of the two swing rods 72 away from the movable shaft 71 via bolts 77. An arc-shaped baffle 76 is positioned at the bottom of each swing rod 72 between the second water inlet 74 and the cleaning plate 78. As the water level in the rainwater collection cellar 1 changes, the swing rods 72 swing relative to the movable shaft 71. The cleaning plates 78 also move with the swing rods 72. When the swing rods 72 move, they can scrape away the deposits on the inner wall of the rainwater collection cellar 1, thus cleaning the inner wall. The arc-shaped baffle 76 can block the turbidity generated during cleaning, preventing debris from falling into the second water inlet 74 and thus preventing it from being extracted with the clean water. This multi-functional and comprehensive mechanism can meet the needs of rainwater collection cellars in agricultural planting.

[0066] A multi-functional clean water extraction mechanism 7 can replace the clean water extraction position control mechanism 6. If both the clean water extraction position control mechanism 6 and the multi-functional clean water extraction mechanism 7 exist, the slip ring 61 will always be located above the movable shaft 71. The buoyancy of the float box 75 causes the end of the swing rod 72 away from the movable shaft 71 to swing upward as the water level in the rainwater cellar 1 rises and downward as the water level in the rainwater cellar 1 falls, thereby also causing the second suction port 74 to always be located below the water surface. The clean water extraction port 46 extracts clean water below the water surface through the second suction hose 73 and the second suction port 74, without extracting the turbid water at the bottom of the rainwater cellar 1. The float box 75 is a plastic box filled with air.

[0067] Example 3, please refer to Figures 1 to 12 This embodiment provides a technical solution: a multifunctional rainwater collection cistern. This embodiment is structurally similar to Embodiment 2, with the difference being:

[0068] It also includes a secondary rainwater filtration mechanism 5, which includes a filter screen mounting ring 51, a conical filter screen 53, a filter screen insert ring 54, and a filter screen cleaning assembly. The filter screen mounting ring 51 is installed on the top of the water inlet cylinder 21 and is connected to the bottom of the conical filter screen 53. The filter screen insert ring 54 is set at the top center of the conical filter screen 53. The top of the extraction common vertical pipe 43 passes through the filter screen insert ring 54, and two filter screen cleaning assemblies are installed on the upper and lower sides of the extraction common vertical pipe 43, respectively.

[0069] The secondary rainwater filtration mechanism 5 also includes positioning posts 52. The bottom of the filter screen mounting ring 51 is provided with four positioning posts 52 in a circular array. The four positioning posts 52 are respectively connected to the four positioning holes at the top of the water inlet cylinder 21. The filter screen mounting ring 51 is installed on the top of the water inlet cylinder 21 by means of the positioning posts 52 and the positioning holes.

[0070] The filter cleaning assembly includes a ring 55, an oblique cleaning brush 56, and fastening bolts 57. Two rings 55 are respectively fitted onto the upper and lower sides of the common vertical tube 43, which is located above and below the filter insert ring 54. Two fastening bolts 57 are threaded to the sides of the two rings 55, and the fastening bolts 57 press against the common vertical tube 43. The rings 55 and the common vertical tube 43 are detachably connected by the fastening bolts 57. Two oblique cleaning brushes 56 are installed on both sides of each ring 55. The bristles of the oblique cleaning brushes 56 are all facing the conical filter 53. The oblique cleaning brushes 56 located above and below the conical filter 53 can clean the debris filtered by the conical filter 53.

[0071] The filter screen mounting ring 51 is used to install the conical filter screen 53. The conical filter screen 53 can filter the water entering the water inlet cylinder 21. The filtered debris is left on the top of the conical filter screen 53. When the common vertical pipe 43 is rotated, it will drive the filter screen cleaning component to rotate. When the filter screen cleaning component rotates, it brushes the upper and lower sides of the conical filter screen 53. The debris filtered down from the upper layer of the conical filter screen 53 falls into the annular cleaning tank 31, which prevents the debris from quickly clogging the filter holes on the conical filter screen 53 and avoids the need for frequent manual cleaning of the conical filter screen 53, thus reducing the frequency of manual intervention.

[0072] It is worth noting that the sludge pumping control solenoid valve 45, water pumping control solenoid valve 47, selection solenoid valve 411, clean water pump 412, sludge pump 414, and power motor 94 disclosed in the above embodiments are all controlled by an external PLC controller, and the control method adopts the method commonly used in the prior art.
