Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, specifically to a device for collecting, purifying, and reusing rainwater from urban roads. Background Technology

[0002] Rainwater harvesting is the process of collecting rainwater, treating it, and then reusing it. It refers to the collection and utilization of rainwater runoff from building roofs and hardened surfaces such as roads and squares. The rainwater is then collected, transported, purified, and stored through various channels. The rainwater is used for greening, landscape water features, washing, and replenishing groundwater sources, in order to achieve the goal of comprehensive utilization of rainwater resources and water conservation.

[0003] A search revealed that CN222456245U discloses a rainwater harvesting, purification, and reuse device for urban roads. The device includes a base, a protective structure at the top of the base, a conduit on one side of a water tank, and a water pump on the other side of the conduit. An agitator is installed inside the tank. A support bracket is mounted at the top of the base, allowing the protective plate to be installed. This support bracket ensures stable installation of the bracket, and the protective plate protects the device from damage due to impact. An elastic rubber pad on one side of the protective plate, made of rubber material, further enhances the plate's elasticity and cushions impacts. At night, the reflector reflects light from vehicle headlights, making the device visible to drivers and preventing collisions. This design achieves the goal of providing convenient protection for the rainwater harvesting, purification, and reuse device for urban roads.

[0004] The aforementioned urban road rainwater harvesting, purification, and reuse device utilizes a water tank and internal filter to filter and collect rainwater. However, in practical applications, it still suffers from the following drawbacks: 1. The filter is located inside the water tank to filter solid impurities, which leads to a large accumulation of solid impurities on the top of the filter. These impurities must be manually removed, making the cleaning operation inconvenient and inefficient. 2. During prolonged filtration, impurities inevitably become trapped in the filter pores, causing blockage. Since the filter is horizontally installed inside the water tank, cleaning is difficult, and there is a lack of convenient and efficient cleaning and unblocking mechanisms, resulting in poor ease of use and efficiency of the device. Therefore, this application proposes an urban road rainwater harvesting, purification, and reuse device to solve the above problems. Utility Model Content

The vortex drive assembly is used to drive the flow sleeve to rotate, and the rotation of the flow sleeve drives the conical stainless steel filter screen and the conical fine filter screen to rotate. The rotation of the conical fine filter screen throws the solids filtered on its outside outwards, and performs preliminary shaking and cleaning work. The backflush cleaning assembly is installed on the water collection tank and mates with the inside of the conical stainless steel filter screen. The backflush cleaning assembly is used to thoroughly backflush and clean the conical stainless steel filter screen and the conical fine filter screen from the inside out as they rotate.

[0017] 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.

[0018] Example 1 like Figure 1 As shown: This embodiment proposes a rainwater collection, purification and reuse device for urban roads, which includes a rainwater collection, purification and reuse device body. The rainwater collection, purification and reuse device body includes a base 1, a protective structure 103 fixed to the top of the base 1, a mixing tank structure 101 fixed to the top of the base 1 and located in the protective structure 103, and a water collection tank 102. A water pump is connected between the bottom right side of the water collection tank 102 and the left side of the mixing tank structure 101 through a pipe.

[0019] In this implementation plan: The existing device {publication (announcement) number}: CN222456245U discloses an urban road rainwater collection, purification and reuse device. The protective structure 103 and the mixing tank structure 101 in this application document adopt the same technical means as in this prior art. These technical means will not be described in detail here. Regarding the main body of this existing device, this application makes further improvements. For details, please refer to the following disclosure. To solve the technical problems existing in this prior art, such as "1. The filter screen is set inside the water tank to filter solid impurities, which will lead to solid impurities being filtered out by the filter screen inside the water tank ... 1. Impurities accumulate on the top of the filter screen, requiring manual removal, which makes the cleaning process inconvenient and inefficient. 2. During long-term filtration, impurities inevitably become trapped in the filter holes, causing blockage. Since the filter screen is installed horizontally inside the water tank, cleaning is difficult and lacks a convenient and efficient cleaning mechanism, resulting in poor usability and efficiency of the device. In summary, this problem is a real and difficult-to-solve issue. Therefore, to address this technical problem, a quick-cleaning and unblocking filter mechanism that does not require disassembly has been added to this application.

[0020] It should be noted that: the protective structure 103 and the mixing tank structure 101 are technologies already disclosed in the prior art, therefore the internal structure is not fully described. The accessories used are disclosed in publication number CN222456245U, and their performance can be referred to publication number CN222456245U (that is, the "protective structure, protective plate, rubber pad, reflector, bracket, support frame; tank body, mixing mechanism, servo motor, mixing shaft, mixing, through hole, water outlet, material box and pump components" disclosed in this prior art).

[0021] Furthermore: like Figures 1 to 3 As shown, a quick-cleaning and unblocking filter mechanism that does not require disassembly is installed on the water collection tank 102; The quick-cleaning, non-disassembly filtration system includes: Support sleeve 2 is connected and fixed to the top of water collection tank 102; The flow sleeve 201 is rotatably fitted inside the support sleeve 2, and its inner top is set as a bowl-shaped structure that is larger at the top and smaller at the bottom; two first bearings are fixedly fitted inside the support sleeve 2, and the inner ring of the first bearing is fixedly fitted to the outer side of the flow sleeve 201, so as to achieve the effect of rotating the flow sleeve 201. A conical stainless steel filter screen cover 205 is fixedly connected to the top of the flow sleeve 201, and a conical fine filter screen cover 2051 is fixedly connected to its outer side. The conical stainless steel filter screen cover 205 is used to support the conical fine filter screen cover 2051. The conical fine filter screen cover 2051 is used to filter and intercept solids in rainwater. The filtered rainwater flows downward into the flow sleeve 201 through the filter holes of the conical fine filter screen cover 2051, and then flows into the water collection tank 102 for collection and utilization. U-shaped baffle 202 is fixedly connected to the top right side of water collection tank 102; The vortex drive assembly is installed on the right side of the water collection tank 102 and fixedly sleeved on the outside of the flow sleeve 201. The vortex drive assembly is used to drive the flow sleeve 201 to rotate. The rotation of the flow sleeve 201 drives the conical stainless steel filter screen 205 and the conical fine filter screen 2051 to rotate. The rotation of the conical fine filter screen 2051 throws the solids filtered on its outside outwards, performing preliminary shaking and cleaning work. The back-flushing cleaning assembly is installed on the water collection tank 102 and cooperates with the inner side of the conical stainless steel filter screen 205. The back-flushing cleaning assembly is used to thoroughly back-flush and clean the conical stainless steel filter screen 205 and the conical fine filter screen 2051 from the inside to the outside when they rotate. In this embodiment, a conical guide cover 204 is fixedly fitted on the top of the outer side of the flow sleeve 201, and the supporting circular sleeve 2 is located inside the conical guide cover 204 and does not contact its inner side; the diameter of the filter hole of the conical fine filter screen cover 2051 is smaller than the diameter of the filter hole of the conical stainless steel filter screen cover 205.

[0022] Furthermore, such as Figure 2 and 3 As shown, the rotary drive assembly includes an umbrella-shaped gear ring 203 fixedly sleeved on the outside of the flow sleeve 201, an umbrella-shaped gear 2031 meshing on the right side of the umbrella-shaped gear ring 203, and a drive motor 2032 located inside the U-shaped baffle 202 fixedly installed on the top right side of the water collection tank 102. The output shaft of the drive motor 2032 extends into the water collection tank 102 and is fixedly connected to the right side of the umbrella gear 2031. In this embodiment, an annular partition 207 is fixedly sleeved inside the water collection tank 102. The annular partition 207 is rotatably sleeved on the bottom outer side of the flow sleeve 201. The bevel gear ring 203 and the bevel gear 2031 are both located above the annular partition 207. The annular partition 207 serves to safely shield the bevel gear ring 203 and the bevel gear 2031. A sealed bearing is fixedly sleeved inside the annular partition 207. The inner ring of the sealed bearing is fixedly sleeved on the bottom outer side of the flow sleeve 201, which serves to seal the flow sleeve 201 for rotational installation on the outside. In this embodiment, the bevel gear 203, bevel gear 2031, and drive motor 2032 work together. The drive motor 2032 drives the bevel gear 2031 to rotate, and the bevel gear 2031 drives the bevel gear 203 to rotate. The bevel gear 203 drives the conical stainless steel filter screen 205 and the conical fine filter screen 2051 to rotate through the flow sleeve 201. The rotation of the conical fine filter screen 2051 throws the solids filtered on its outside away, performing a preliminary shaking and cleaning operation.

[0023] Furthermore, such as Figure 2 and 3 As shown, the backflushing cleaning assembly includes an L-shaped branch pipe 206 embedded and fixed on the inner wall of the right side of the water collection tank 102. The top end of the L-shaped branch pipe 206 is connected to an L-shaped pipe 2061 that is inclined and located inside a conical stainless steel filter screen 205. The left end of the L-shaped pipe 2061 is set as a sealing structure. Multiple nozzles 2062 are connected and fixed on the right side and top of the L-shaped pipe 2061. The multiple nozzles 2062 are located inside the conical stainless steel filter screen 205 and are adapted to its inner right side and inner top. An air pump 2063 is fixedly installed on the inner wall of the right side of the U-shaped baffle 202. The air outlet of the air pump 2063 is connected and fixed to the right end of the L-shaped branch pipe 206 with the same one-way valve 2064 with the left side as the outlet. In this embodiment, a reinforcing rib is fixedly connected between the left inner side of the L-shaped branch pipe 206 and the right inner wall of the water collection tank 102. The L-shaped branch pipe 206 is located inside the flow sleeve 201 and does not contact its inner side. The reinforcing rib provides a strengthening support for the L-shaped branch pipe 206. In this implementation scheme, the L-shaped branch pipe 206, L-shaped pipe 2061, nozzle 2062, air pump 2063, and one-way valve 2064 work together. The air pump 2063 supplies air unidirectionally into the L-shaped branch pipe 206 through the one-way valve 2064. The air is supplied into the L-shaped pipe 2061 and then sprayed outward through multiple nozzles 2062. With the rotation of the conical stainless steel filter screen 205 and the conical fine filter screen 2051, the rotating conical stainless steel filter screen 205 and the conical fine filter screen 2051 are thoroughly back-blown from the inside to the outside to clean and unclog the blockage. This further blows out residual small particulate impurities, further improving the cleaning and unclogging effect.

[0024] It should be noted that the air pump 2063 and drive motor 2032 can be used with an external time control switch. Personnel can use the time control switch to start and stop the air pump 2063 and drive motor 2032 at set times. The preferred time control switch is the Delixi KG316T microcomputer time control switch, which is preferably installed inside the U-shaped baffle 202 and directly electrically connected to the air pump 2063 and drive motor 2032 via wires. Regarding power supply, since urban roads have various power facilities such as lighting equipment and traffic signal power supply, and are equipped with mains power supply facilities, they have complete power supply conditions. Therefore, the electrical components of this device can be connected to the on-site mains power. Specifically, they are connected to the power input interface of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules (not marked in the figure) to form a complete power supply circuit. This power supply scheme adopts the conventional power distribution and switch operation wiring method of municipal equipment, which is a conventional and mature known technology in this field and will not be described in detail here.

[0025] The usage method of this embodiment is as follows: When the urban road rainwater collection, purification and reuse device is used, the conical stainless steel filter screen cover 205 supports the conical fine filter screen cover 2051, the conical fine filter screen cover 2051 filters and intercepts solids in the rainwater, and the filtered rainwater flows downward into the flow sleeve 201 through the filter holes of the conical fine filter screen cover 2051, and then flows into the water collection tank 102 for collection and reuse; During cleaning, personnel turn on the drive motor 2032 and air pump 2063. When the drive motor 2032 starts, it drives the bevel gear 2031 to rotate. The bevel gear 2031 drives the flow sleeve 201 to rotate through the bevel gear ring 203 that meshes with it. The flow sleeve 201 drives the conical stainless steel filter screen cover 205 and the conical fine filter screen cover 2051 to rotate. The rotation of the conical fine filter screen cover 2051 throws the solids filtered on its outside away, performing the initial shaking cleaning work. The rotation quickly throws away the external solids, and the conical fine filter screen cover 2051 is protruding at the top, which makes it convenient and quick to discharge solid impurities without the need for personnel to manually pick up and remove impurities, improving the convenience and efficiency of the slag cleaning operation. When the air pump 2063 starts, it supplies air unidirectionally to the L-shaped branch pipe 206 through the one-way valve 2064. The air is supplied into the L-shaped pipe 2061 and then sprayed outward through multiple nozzles 2062. With the rotation of the conical stainless steel filter screen 205 and the conical fine filter screen 2051, the rotating conical stainless steel filter screen 205 and the conical fine filter screen 2051 are thoroughly back-blown from the inside to the outside to clean and unclog. This further blows out small particulate impurities remaining in the filter holes. No personnel are required to disassemble and remove them for cleaning and unclogging, which improves the efficiency and convenience of cleaning and unclogging.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
