Description

Technical Field

[0001] This utility model relates to the technical field of rainwater storage devices, specifically to an in-well type rainwater storage device. Background Technology

[0002] With the significant increase in the area of ​​paved roads, the permeability of paved surfaces is extremely poor, which severely blocks the natural rainwater infiltration channels. The amount of rainwater infiltration has decreased by more than 80% compared to the natural landform period, leading to increasingly prominent urban flooding problems. Therefore, cities often use rainwater wells to achieve rainwater storage and regulation.

[0003] However, traditional water storage devices mostly use a single filter screen or sand and gravel filtration layer, which cannot effectively intercept pollutants of different particle sizes. Large particles such as leaves, plastic bags, dead branches, and gravel often carried in the initial rainwater flow can easily adhere to the surface of the filter screen and form a blockage, directly obstructing the rainwater drainage channel. Not only can they not achieve the water storage function, but they can also exacerbate the risk of waterlogging and cause poor drainage. Moreover, cleaning requires manual entry into the well, which is time-consuming, labor-intensive, and poses safety hazards.

[0004] Therefore, this utility model proposes an in-well loading rainwater storage device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an in-well rainwater storage device to solve the problems in the prior art where debris easily forms blockages, leading to poor drainage and time-consuming and laborious cleaning.

[0006] The technical solution adopted by this utility model to solve its technical problem is: An in-well type rainwater storage device includes a drainage ditch, a drainage well cover connected to the top of the drainage ditch, a filter well connected to one side of the drainage ditch, a drainage well connected to the other side of the drainage ditch, a drainage pipe connected to the bottom of the drainage well, and the drainage pipe communicating with a water storage tank; a first filter screen is detachably connected inside the drainage ditch, the first filter screen is located at the upper end of the drainage ditch and is inclined towards the filter well, a first water outlet communicating with the filter well is opened at the upper end of the drainage ditch corresponding to the first filter screen, a second filter screen is connected inside the filter well and is located at the lower end of the first filter screen, a second water outlet communicating with the filter well is opened at the bottom of the drainage ditch, and a third water outlet communicating with the drainage well is opened at the upper end of the drainage ditch.

[0007] Furthermore, a third filter screen is detachably connected between the drainage ditch and the drainage well.

[0008] Furthermore, a fourth filter screen is detachably connected to the drainage well corresponding to the drainage pipe.

[0009] Furthermore, both the drainage well and the filter well are provided with a cover on top, and a pull ring is connected to the cover.

[0010] Furthermore, a first locking block is connected to the first filter screen in the drainage ditch, and a first locking groove is opened in the first filter screen corresponding to the first locking block; a second locking block is connected to the second filter screen in the filter well, and a second locking groove is opened in the second filter screen corresponding to the second locking block.

[0011] Furthermore, the pore sizes of the first filter, second filter, third filter, and fourth filter decrease sequentially.

[0012] Furthermore, the surfaces of the first, second, third, and fourth filter screens are all coated with a wear-resistant and corrosion-resistant coating, the coating being made of polytetrafluoroethylene, while the first, second, third, and fourth filter screens are made of stainless steel.

[0013] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: The first filter screen of this utility model intercepts large particles of debris and guides them to the filter well through an inclined design. The debris eventually falls into the filter well for temporary storage, preventing the accumulation of debris from clogging the main channel of the drainage ditch. When the water flow is too large, the third water outlet at the upper end of the drainage ditch flows to the drainage well, preventing the drainage ditch from overflowing. At the same time, it can settle rainwater, ensuring that the rainwater drainage channel is unobstructed and avoiding waterlogging.

[0014] The first, second, third, and fourth filter screens of this invention have progressively smaller pore sizes, allowing for targeted interception of pollutants of different particle sizes. This avoids clogging of a single filter screen due to the adhesion of mixed pollutants.

[0015] The cover of this utility model is equipped with a pull ring, and the first filter screen has a first slot corresponding to the first locking block, and the second filter screen has a second slot corresponding to the second locking block. The detachable structure allows the first and second filter screens to be directly removed for cleaning or replacement. Workers can quickly remove the filter screens for cleaning or replacement without entering the well, which can quickly restore the operation of the device in an emergency, save labor costs, improve maintenance efficiency, and avoid the safety risks of downhole operations.

[0016] The first, second, third, and fourth filters of this utility model are made of stainless steel and coated with a wear-resistant and corrosion-resistant polytetrafluoroethylene coating, which can resist rainwater erosion and pollutant corrosion, reduce filter wear and replacement frequency, and reduce long-term use costs.

[0017] This invention achieves rapid rainwater collection and step-by-step purification through a graded filtration and flow guidance design, ensuring the cleanliness of rainwater entering the storage tank while preventing channel blockage and ensuring stable storage function.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0021] like Figure 1-5As shown, an in-well type rainwater storage device includes a drainage ditch 1, a drainage well cover 2 connected to the top of the drainage ditch 1, a filter well 3 connected to one side of the drainage ditch 1, a drainage well 4 connected to the other side of the drainage ditch 1, a drainage pipe 5 connected to the bottom of the drainage well 4, and the drainage pipe 5 communicating with a water storage tank; a fourth filter screen 6 is detachably connected to the drainage well 4 corresponding to the drainage pipe 5. Both the drainage well 4 and the filter well 3 are topped with a cover 7, and a pull ring 8 is connected to the cover 7.

[0022] Furthermore, a first filter screen 9 is detachably connected inside the drainage ditch 1. The first filter screen 9 is located at the upper end of the drainage ditch 1 and is inclined towards the filter well 3. A first water outlet 10 communicating with the filter well 3 is opened at the upper end of the drainage ditch 1 corresponding to the first filter screen 9. A second filter screen 11 is connected inside the filter well 3 and is located at the lower end of the first filter screen 9. A second water outlet 12 communicating with the filter well 3 is opened at the bottom of the drainage ditch 1. A third filter screen 13 is detachably connected between the drainage ditch 1 and the drainage well 4. A third water outlet 14 communicating with the drainage well 4 is opened at the upper end of the drainage ditch 1.

[0023] Furthermore, a first locking block 15 is connected to the first filter screen 9 in the drainage ditch 1, and a first locking groove 16 is opened in the first filter screen 9 corresponding to the first locking block 15; a second locking block 17 is connected to the second filter screen 11 in the filter well 3, and a second locking groove 18 is opened in the second filter screen 11 corresponding to the second locking block 17.

[0024] Furthermore, the pore sizes of the first filter screen 9, the second filter screen 11, the third filter screen 13, and the fourth filter screen 6 decrease sequentially. The surfaces of the first filter screen 9, the second filter screen 11, the third filter screen 13, and the fourth filter screen 6 are all coated with a wear-resistant and corrosion-resistant coating made of polytetrafluoroethylene, while the first filter screen 9, the second filter screen 11, the third filter screen 13, and the fourth filter screen 6 are made of stainless steel.

[0025] The working process of this utility model is as follows: First, rainwater flows into drainage ditch 1 through drainage well cover 2. After entering drainage ditch 1, the rainwater first comes into contact with the first filter screen 9, which is inclined at the top. The first filter screen 9 has the largest pore size and prioritizes intercepting large particles of debris such as leaves, plastic bags, and dead branches. Guided by the inclined angle, the intercepted debris will naturally slide towards the first water outlet 10 and eventually fall into the filter well 3 for temporary storage, so as to avoid the accumulation of debris and blockage of the main channel of drainage ditch 1. Rainwater, initially filtered by the first filter screen 9, flows downwards along the drainage ditch 1. Some of the rainwater separates from the debris temporarily stored in the filter well 3, and is then filtered again by the second filter screen 11 to remove medium-sized pollutants such as gravel. It then enters the filter well 3 through the second inlet 12 at the bottom. The filtered rainwater then flows to the drainage well 4 through the third filter screen 13, where finer pollutants are further intercepted, ensuring improved cleanliness of the rainwater entering the drainage well 4. When the water flow is too large, the third inlet 14 at the top of the drainage ditch 1 directs the water to the drainage well 4, preventing overflow and allowing for rainwater sedimentation. Finally, the rainwater in the drainage well 4 is filtered by the removable fourth filter screen 6 and then flows into the storage tank through the bottom drainage pipe 5, achieving rainwater regulation and storage.

[0026] When contaminants adhere to the filter screens, workers do not need to enter the well; they can simply open the covers 7 of the filter well 3 and the drainage well 4 using the pull ring 8 on the cover 7. The first filter screen 9 has a first slot 16 corresponding to the first locking block 15, and the second filter screen 11 has a second slot 18 corresponding to the second locking block 17. These are detachable structures, allowing the first filter screen 9 and the second filter screen 11 to be directly removed for cleaning or replacement, thus enabling the device to be quickly restored to operation in emergencies.
