Description

Technical Field

[0001] The utility model belongs to the technical field of recycling and purification, and in particular relates to a rainwater recycling device for urban park green land. Background Art

[0002] When the park is designed and constructed, rainwater collection ports are set up on the road surface. Rainwater washes foreign objects on the road surface along the rainwater collection ports and enters the rainwater recycling device. Although the rainwater recycling device is equipped with a filter to pre-filter the rainwater, the filter is very easy to get clogged, requiring workers to frequently clean the leaky net, which is time-consuming and labor-intensive.

[0003] Prior art, such as the document with authorization announcement number CN217580380U, discloses a rainwater collection, purification and reuse device for an urban park, including a box body and a controller. A water purification chamber is opened in the box body, and a filter assembly is arranged in the water purification chamber. The filter assembly includes two groups of screw rods, one end of the screw rod passes through the outside of the box body and is provided with bevel gear 1, and a shaft rod is rotatably arranged on one side of the box body, and bevel gear 2 is arranged at both ends of the shaft rod, and bevel gear 2 is meshed with bevel gear 1. Brush plates are arranged on the two groups of screw rods, and a filter plate parallel to the screw rod is arranged under the brush plate. The controller is electrically connected to a water immersion sensor, a motor, a water pump and a water level sensor.

[0004] The working principle of the above structure is as follows: after rainwater flows into the device through the water inlet pipe, the water immersion sensor detects the presence of water flow and sends an electrical signal to the controller. The controller controls the motor to drive the screw, and the brush plate threaded on the screw will slide repeatedly. The brush plate cleans the dirt on the filter plate while moving, and the dirt falls into the dirt collection basket through the sewage outlet. At the same time, the filtered rainwater falls onto the fixed plate, and is filtered twice by multiple groups of purification pipes installed on the fixed plate, and finally flows into the water collection chamber. When the water level in the water collection chamber exceeds the installation height of the water level sensor, the water level sensor sends an electrical signal to the controller, and the controller controls the water pump to transport the rainwater in the water collection chamber to the external water storage tank for centralized storage.

[0005] However, the device still has the following problems: the filter assembly composed of the screw, bevel gear, shaft, pulley and the like has a complex structure, and the threaded connection structure is easily corroded under water erosion, which has the disadvantage of high maintenance cost.

[0032] The utility model provides a rainwater recycling device for urban park green land, comprising a cylinder 11, a first feed port 12 arranged at one side of the upper end of the cylinder 11, a water outlet 13 arranged at one side of the lower end of the cylinder 11, a rotating column 21 rotatably mounted on the inner top wall of the cylinder 11, a filter plate 22 arranged at the end of the rotating column 21 and slidably connected to the inner side wall of the cylinder 11, a cleaning block 23 arranged on the inner top wall of the cylinder 11 away from the end of the first feed port 12 and located at the upper end of the filter plate 22, a waste box 24 arranged in the cylinder 11 and located at the lower end of the cleaning block 23, a receiver 25 arranged on the inner wall of the cylinder 11, a transmitter 26 arranged at the end of the filter plate 22 and used for transmitting a signal to the receiver 25, a purification plate 27 arranged in the cylinder 11, a plurality of purification members 28 detachably mounted on the purification plate 27, and a water level sensor 29 arranged on the inner wall of the cylinder 11 and located at the lower end of the purification plate 27.

[0033] The first feed port 12 is provided with a valve for controlling the opening and closing of the first feed port 12, and the valve is connected to a controller (not shown in the figure). The water outlet 13 is provided with a water pump (not shown in the figure), which is also connected to the controller and is used to transport the purified water in the cylinder 11 out of the cylinder 11. The filter plate 22 rotates in the cylinder 11 driven by the rotating column 21, and the filter plate 22 is located between the cleaning block 23 and the waste box 24 in the vertical direction. The receiver 25 is located at the lower end of the first feed port 12, and the transmitter 26 is installed at the edge of the filter plate 22 and rotates with the rotation of the filter plate 22. When the transmitter 26 is driven to the lower end of the receiver 25, the receiver 25 can receive the signal sent by the transmitter 26 and transmit the signal to the controller to control the opening and closing of the valve.

[0034] In this embodiment, the purification plate 27 is tiltedly arranged in the cylinder 11, and the vertical height of the end of the purification plate 27 located at the lower end of the first feed port 12 is greater than the end of the purification plate 27 located at the lower end of the waste box 24. This arrangement can ensure that the water body can pass through the entire purification plate 27 to ensure the purification effect; the purification component 28 is an existing structure, and the interior can be filled with filter materials such as activated carbon, so it is not repeated in this embodiment.

[0035] The working principle of this embodiment is as follows: rainwater with impurities enters the cylinder 11 from the first feed port 12, and the impurities are intercepted on the filter plate 22, and the water flows into the lower part of the cylinder 11; after a period of time, the impurities accumulated on the filter plate 22 are too much to affect the filtering effect, and the rotating column 21 drives the filter plate 22 to rotate so that the impurities rotate to the other side of the cylinder 11. During the process of the filter plate 22 rotating one circle, the impurities are intercepted by the cleaning block 23 and cannot rotate with the filter plate 22, and finally fall into the waste box 24. The water initially filtered by the filter plate 22 falls to the purification plate 27 and is filtered again by the purification member 28, and finally falls to the lower end of the cylinder 11 for storage. When the water level sensor 29 detects that the water level at the lower end of the cylinder 11 reaches the critical value, the water level sensor 29 sends a signal to the controller, and the controller controls the water pump to start and discharge the purified water out of the cylinder 11.

[0036] It should be noted that the projection area of ​​the filter plate 22 cannot exceed 2 / 3 of the projection area inside the cylinder 11, so as to ensure that the filter plate 22 will not block the opening of the waste box 24 for receiving waste during the rotation process, and ensure that the waste can smoothly enter the waste box. In addition, because only when the transmitter 26 is located at the lower end of the receiver 25, the receiver 25 can receive the signal and transmit it to the controller, and the controller controls the valve of the first feed port 12 to open / close. When the receiver 25 does not receive the signal, it means that the filter plate 22 is not completely at the lower end of the first feed port 12, so the valve is closed at this time.

[0037] In this embodiment, the filter plate 22 includes a semicircular plate body 221, a filter hole 222 arranged on the semicircular plate body 221, and a ball 223 arranged on the end of the semicircular plate body 221; an annular groove 224 connected to the ball 223 is arranged on the inner wall of the cylinder 11. The purpose of such a setting is that the design of the semicircular plate body can not only ensure that the filter plate 22 is fully fitted with the inner wall of the cylinder 11 to avoid affecting the filtering effect, but also reduce the friction loss between the filter plate 22 and the inner wall of the cylinder 11 to ensure the service life and stability of the structure; the filter hole 222 has an aperture range of 0.1~1cm, which is used to filter large particles of impurities mixed in rainwater; the setting of the ball 223 and the annular groove 224 is used to further reduce the wear between the filter plate 22 and the inner wall of the cylinder 11, and also improve the tightness and stability of the connection between the two.

[0038] In this embodiment, the cleaning block 23 includes a block body 231, a mounting cavity 232 disposed in the block body 231, and a driving assembly 233 disposed in the mounting cavity 232 and used to drive the rotating column 21 to rotate; the vertical height of the lower surface of the block body 231 gradually increases along the rotation direction of the filter plate 22. The inclined surface of the lower surface of the block body 231 makes the space through which the filter plate 22 passes narrower from wide, ensuring that all impurities enter the waste box 24, and preventing impurities from being stuck in the space between the block body 231 and the waste box 24.

[0039] In this embodiment, the driving assembly 233 includes a motor 2331 arranged in the installation cavity 232, a rotating rod 2332 connected to the output end of the motor 2331 and passing through the block 231, a first bevel gear 2333 arranged on the end of the rotating rod 2332, and a second bevel gear 2334 arranged on the rotating column 21 and meshing with the bevel gear 2333.

[0040] In this embodiment, the waste box 24 is provided with a second feed port 241 at the upper end, and a discharge port 242 is provided at the side end of the waste box 24. A sealing door 243 is provided on the discharge port 242, and a handle (not shown in the figure) is provided on the sealing door 243. The discharge port 242 penetrates the inner wall of the cylinder 11, and the sealing door 243 can simultaneously block the opening on the inner wall of the cylinder 11 and the discharge port 242. When impurities accumulate in the waste box 24, the impurities in the waste box 24 can be cleaned by opening the sealing door 243.

[0041] Compared with the prior art, the recovery device provided in this embodiment has the following advantages: first, the device has only one power source, namely the driving assembly, and has a simple structure. The key transmission parts (motor, bevel gear, etc.) in the driving assembly are not in direct contact with rainwater, which can avoid rust and increase the service life of the device. Second, large particles of impurities in the rainwater are removed by the filter plate, and small particles of impurities in the rainwater are filtered again by the purification plate, thereby ensuring the purification effect of rainwater, and the two-layer plate body is not easy to be blocked, which has the advantages of long service life and low maintenance cost.

[0042] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
