[0002] With the acceleration of urbanization and the promotion of the concept of sponge city construction, parks and green spaces, as an important part of the urban ecosystem, are receiving increasing attention for their efficient utilization of rainwater resources and their drainage and flood control functions. Traditional park rainwater management models often adopt a "rapid discharge" strategy, directly discharging rainwater into the municipal system through surface runoff or pipe networks. This approach not only leads to a large waste of water resources but may also exacerbate urban non-point source pollution due to pollutants such as sediment, fallen leaves, and oil carried by rainwater, causing blockages that prevent rainwater collection. In addition, the high sediment content in the water makes it difficult to filter. Utility Model Content

This mechanism has the advantage of reducing sediment during collection and solves the problem that traditional garden rainwater management often adopts a "rapid discharge" strategy, directly discharging rainwater into the municipal system through surface runoff or pipe networks. This method not only leads to a large waste of water resources but may also exacerbate urban non-point source pollution due to pollutants such as sediment, fallen leaves, and oil carried by rainwater, causing blockages that prevent rainwater collection. In addition, the high sediment content in the water makes filtration difficult.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a water tank, a cover plate, a cylinder, a connecting pipe, a movable ring, and a movable shaft. The cover plate is installed on the top of the water tank, the connecting pipe is installed on the top of the cover plate, and a cylinder located outside the connecting pipe is installed on the top of the cover plate. The movable ring is sleeved on the top surface of the connecting pipe, and the movable shaft is installed on the top of the movable ring. Several movable shafts are provided, and the several movable shafts are evenly distributed. A collection mechanism is installed on the inner wall of the movable shaft, and a purification component is installed on the bottom of the inner wall of the water tank.

[0005] In a preferred embodiment of this invention, the collecting mechanism includes a connecting rod, which is movably mounted to the inner wall of the movable shaft. A folded cloth is installed on the surface of the connecting rod, and the surface of the folded cloth has a waterproof coating. A baffle is installed on the top of each connecting rod.

[0006] As a preferred embodiment of this utility model, a movable groove is provided on one side of the baffle, a spring is installed on one side of the movable groove, and a push block is installed on the other end of the spring.

[0007] As a preferred embodiment of this utility model, limiting grooves are provided on both sides of the inner wall of the cylinder, the two sides of the movable ring are movably connected to the inner wall of the limiting groove, a lead screw is movably installed on the left side of the top of the inner wall of the limiting groove, one side of the movable ring is threadedly connected to the lead screw, an upper motor is installed on the inner wall of the cover plate, and the output end of the upper motor is fixedly connected to the bottom of the lead screw.

[0008] As a preferred embodiment of this utility model, the purification component includes a grid plate, which is installed at the bottom of the inner wall of the water tank. A water pumping pipe is installed on the right side of the inner wall of the water tank, and a drain trough is provided at the bottom of the inner wall of the water tank.

[0009] As a preferred embodiment of this utility model, a water purification device is installed on the right side of the water pumping pipe, and a sewage pipe is connected to the right side of the bottom of the sewage discharge tank, with a solenoid valve installed on the surface of the sewage pipe.

[0010] As a preferred embodiment of this invention, a lower motor is installed at the bottom of the inner wall of the sewage trough, and a screw rod is installed at the output end of the lower motor.

[0011] As a preferred embodiment of this invention, a BOD water quality sensor is installed at the bottom of the left side of the inner wall of the water tank, an ultrasonic water level sensor is installed at the top of the left side of the inner wall of the water tank, and a control device is installed at the top of the right side of the inner wall of the water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model incorporates a water tank for rainwater storage. A cover seals the top of the tank, and a connecting pipe transports the collected rainwater into the tank for storage. A movable ring moves up and down on the surface of a cylindrical container. During use, the portion below the cylinder can be buried in the soil to reduce space usage, or it can be installed directly on the ground. A suitable installation method can be chosen based on requirements. During rain, the movable ring drives the collection mechanism upwards, unfolding to collect rainwater and transport it to the water tank. This reduces impurities and sediment in the water, solving the problem of traditional garden rainwater management methods that often employ a "rapid discharge" strategy, directly discharging rainwater into the municipal system via surface runoff or pipe networks. This method not only wastes a large amount of water resources but may also exacerbate urban non-point source pollution due to pollutants such as sediment, fallen leaves, and oil carried by the rainwater, leading to blockages that prevent rainwater collection. Furthermore, the high sediment content in the water makes filtration difficult. This utility model offers the advantage of reducing sediment during collection.

[0014] 2. This utility model, by setting up a collection mechanism, allows the connecting rod to break free from the cylinder's limitation when it rains, and unfold under the limitation of the movable shaft. During the unfolding process, the folded cloth unfolds, collecting rainwater through the folded cloth. This reduces the amount of sediment in the rainwater, alleviates the pressure on water purification, and eliminates the need for frequent replacement of filter materials. At the same time, the waterproof material prevents the folded cloth from absorbing rainwater when it falls on it, causing raindrops to converge towards the center and flow into the connecting pipe.

[0015] 3. This utility model uses a movable groove spring and push blocks. After the moving ring moves to the top, it releases the limit on the connecting rod. At this time, the spring pushes the push blocks, and under the push of multiple push blocks, the connecting rods move away from each other and unfold the folded cloth. The movable shaft limits the angle of the connecting rods. After the rain ends, the moving ring moves downward and the connecting rods are merged and reset under the limit of the cylinder. At the same time, the folded cloth is folded, and the push blocks squeeze each other and are stored in the movable groove. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, the present invention includes a water tank 1, a cover plate 2, a cylinder 3, a connecting pipe 4, a movable ring 5, and a movable shaft 6. The cover plate 2 is installed on the top of the water tank 1, the connecting pipe 4 is installed on the top of the cover plate 2, the cylinder 3 located outside the connecting pipe 4 is installed on the top of the cover plate 2, the movable ring 5 is sleeved on the top of the surface of the connecting pipe 4, the movable shaft 6 is installed on the top of the movable ring 5, and there are several movable shafts 6, which are distributed at equal distances. A collection mechanism 7 is installed on the inner wall of the movable shaft 6, and a purification component 8 is installed on the bottom of the inner wall of the water tank 1.

[0024] refer to Figure 3 The collecting mechanism 7 includes a connecting rod 71, which is movably installed on the inner wall of the movable shaft 6. A folded cloth 72 is installed on the surface of the connecting rod 71, and the surface of the folded cloth 72 has a waterproof coating. A baffle 73 is installed on the top of the connecting rod 71.

[0025] As a technical optimization of this utility model, by setting up a collection mechanism 7, when it rains, the moving ring 5 moves upward, so that the connecting rod 71 is freed from the limitation of the cylinder 3, and the connecting rod 71 unfolds under the limitation of the movable shaft 6. During the unfolding process, the folded cloth 72 unfolds, and the rainwater is collected by the folded cloth 72, reducing the silt in the rainwater, reducing the pressure of water purification, and eliminating the need to frequently replace the filter material. At the same time, the waterproof material can prevent the folded cloth 72 from absorbing the rainwater when it falls on it, so that the rainwater droplets gather in the middle and flow into the connecting pipe 4.

[0026] refer to Figure 5 A movable groove 9 is provided on one side of the baffle 73. A spring 10 is installed on one side of the movable groove 9, and a push block 11 is installed on the other end of the spring 10.

[0027] As a technical optimization of this utility model, by setting the movable groove 9, spring 10 and push block 11, after the moving ring 5 moves to the top, the limit on the connecting rod 71 is released. At this time, the spring 10 pushes the push block 11. Under the push of multiple push blocks 11, the connecting rod 71 moves away from each other and unfolds the folded cloth 72. The movable shaft 6 limits the angle of the connecting rod 71. After the rain ends, the moving ring 5 moves downward and the connecting rod 71 is merged and reset under the limit of the cylinder 3. At the same time, the folded cloth 72 is folded, and the push blocks 11 squeeze each other and are stored in the movable groove 9.

[0028] refer to Figure 3 Limiting grooves 12 are provided on both sides of the inner wall of the cylinder 3. The two sides of the moving ring 5 are movably connected to the inner wall of the limiting groove 12. A lead screw 13 is movably installed on the left side of the top of the inner wall of the limiting groove 12. One side of the moving ring 5 is threadedly connected to the lead screw 13. An upper motor 14 is installed on the inner wall of the cover plate 2. The output end of the upper motor 14 is fixedly connected to the bottom of the lead screw 13.

[0029] As a technical optimization of this utility model, by setting a limiting groove 12, a lead screw 13 and an upper motor 14, and controlling the rotation direction of the upper motor 14 by the control device 25, the moving direction of the moving ring 5 is controlled. Under the drive of the upper motor 14, the lead screw 13 is rotated, and the lead screw 13 pushes the moving ring 5 to move through the thread.

[0030] refer to Figure 2 The purification component 8 includes a grid plate 81, which is installed at the bottom of the inner wall of the water tank 1. A water pumping pipe 82 is installed on the right side of the inner wall of the water tank 1, and a sewage discharge trough 83 is provided at the bottom of the inner wall of the water tank 1.

[0031] As a technical optimization of this utility model, by setting the purification component 8, the grid plate 81 can block the water at the bottom of the water tank 1 to form turbulence, preventing the sediment from floating up due to the turbulence. The water tank 1 allows the water to settle, causing the sediment in the water to settle downwards. After settling, the water with less impurities at the top of the grid plate 81 in the water tank 1 is extracted through the water pipe 82. The water tank 1 can perform preliminary purification of the water, and the sewage trough 83 can gather the sediment at the bottom towards the middle.

[0032] refer to Figure 2 A water purification device 18 is installed on the right side of the water pumping pipe 82, and a sewage pipe 19 is connected to the bottom right side of the sewage tank 83. A solenoid valve 20 is installed on the surface of the sewage pipe 19.

[0033] As a technical optimization of this utility model, by setting up a water purification device 18, a drain pipe 19, and a solenoid valve 20, water from multiple water tanks 1 is transported to the water purification device 18 through a water pumping pipe 82 for purification and then discharged. Because the content of sediment and impurities in the water is reduced, the pressure of the water purification device 18 can be reduced, avoiding frequent replacement of filter media. The drain pipe 19 can discharge sediment from the tank. The solenoid valve 20 can control the opening and closing of the drain pipe 19. During sewage discharge, the solenoid valve 20 is controlled by the control device 25.

[0034] refer to Figure 2 A lower motor 21 is installed at the bottom of the inner wall of the sewage trough 83, and a screw rod 22 is installed at the output end of the lower motor 21.

[0035] As a technical optimization of this utility model, by setting a lower motor 21 and a screw rod 22, when sewage needs to be discharged, the lower motor 21 is started by the control device. The lower motor 21 drives the screw rod 22 to push the mud and sand downwards and into the sewage pipe 19. The mud and sand are discharged through the sewage pipe 19. The screw rod 22 can prevent the mud and sand from clogging the bottom of the sewage trough 83.

[0036] refer to Figure 2 A BOD water quality sensor 23 is installed at the bottom left side of the inner wall of water tank 1, an ultrasonic water level sensor 24 is installed at the top left side of the inner wall of water tank 1, and a control device 25 is installed at the top right side of the inner wall of water tank 1.

[0037] As a technical optimization of this utility model, by setting up a BOD water quality sensor 23, an ultrasonic water level sensor 24 and a control device 25, the BOD water quality sensor 23 can detect the water quality in the water tank 1, the ultrasonic water level sensor 24 can detect the water level, and the control device 25 can control the upper motor 14, the lower motor 21, the solenoid valve 20, the BOD water quality sensor and the ultrasonic water level sensor 24.

[0038] The working principle and usage process of this utility model are as follows: During use, the water tank 1 stores rainwater, the cover plate 2 seals the top of the water tank 1, and the connecting pipe 4 transports the collected rainwater into the water tank 1 for storage. The moving ring 5 can move up and down on the surface of the cylinder 3. During use, the part below the cylinder 3 can be buried in the soil to reduce space occupation, or it can be directly installed on the ground. A suitable installation method can be selected according to requirements. When it rains, the moving ring 5 moves upward, causing the connecting rod 71 to break free from the limitation of the cylinder 3. The connecting rod 71 unfolds under the limitation of the movable shaft 6, and during the unfolding process, it drives the folding cloth 72 to unfold, collecting rainwater through the folding cloth 72. This reduces sediment in rainwater, alleviating the pressure on water purification and eliminating the need for frequent filter material replacements. The waterproof material prevents rainwater from being absorbed by the folded fabric 72, causing raindrops to converge and flow into the connecting pipe 4. After the moving ring 5 reaches the top, the limiting position on the connecting rod 71 is released. At this point, the spring 10 pushes the push block 11, causing the connecting rod 71 to move away from each other and unfold the folded fabric 72. The movable shaft 6 limits the angle of inclination of the connecting rod 71. After the rain ends, the moving ring 5 moves downwards, and the connecting rod 71 rejoins and resets under the limiting position of the cylinder 3. Simultaneously, the folded fabric... The cloth 72 is folded, and the push blocks 11 are squeezed together and stored in the movable groove 9. The rotation direction of the upper motor 14 is controlled by the control device 25, which controls the movement direction of the moving ring 5. Driven by the upper motor 14, the lead screw 13 rotates. The lead screw 13 pushes the moving ring 5 through the thread. The grid plate 81 can block the water at the bottom of the water tank 1 from forming turbulence, preventing the sediment from floating up due to turbulence. The water tank 1 allows the water to settle, allowing the sediment in the water to settle downwards. After settling, the water with less impurities at the top of the grid plate 81 in the water tank 1 is pumped out through the water pipe 82. The water tank 1 can perform preliminary purification of the water. The sewage tank 83 can collect the sediment at the bottom towards the middle. Water from multiple water tanks 1 is transported to the water purification equipment 18 through the water pumping pipe 82 for purification, and then discharged. Because the content of sediment and impurities in the water is reduced, the pressure on the water purification equipment 18 can be reduced, avoiding frequent replacement of filter media. The sewage pipe 19 can discharge sediment from the tank. The solenoid valve 20 can control the opening and closing of the sewage pipe 19. During sewage discharge, the solenoid valve 20 is controlled by the control device 25. When sewage discharge is required, the lower motor 21 is started by the control device. The lower motor 21 drives the screw rod 22 to push the sediment downward and into the sewage pipe 19, where it is discharged. The screw rod 22 can prevent sediment from clogging the bottom of the sewage tank 83.

[0039] In summary, this garden rainwater collection, drainage, and purification mechanism stores rainwater in a water tank 1. A cover plate 2 seals the top of the water tank 1, and a connecting pipe 4 transports the collected rainwater into the water tank 1 for storage. A moving ring 5 can move up and down on the surface of a cylinder 3. During use, the portion below the cylinder 3 can be buried in the soil to reduce space occupation, or it can be installed directly on the ground. The appropriate installation method can be selected according to needs. When it rains, the moving ring 5 drives the collection mechanism 7 to move upward and then unfold to collect rainwater, which is then transported into the water tank 1. This reduces impurities and sediment in the water, solving the problem that traditional garden rainwater management often adopts a "rapid discharge" strategy, directly discharging rainwater into the municipal system through surface runoff or pipe networks. This method not only leads to a large waste of water resources but may also exacerbate urban non-point source pollution due to pollutants such as sediment, fallen leaves, and oil carried by the rainwater, causing blockages that prevent rainwater collection. At the same time, the high sediment content in the water makes filtration difficult.
