Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a rapid drainage grid filtration device for sunken ground in a park. Background Technology

[0002] With the acceleration of urbanization, the design of sunken green spaces in public areas such as parks and squares has become increasingly popular. These spaces, created by the subsidence of the terrain, form natural water storage areas and can effectively alleviate urban flooding during heavy rains. However, traditional sunken ground drainage systems generally have functional defects: existing devices mostly use a single grille or simple filter structure, which is easily clogged by leaves, silt, and other debris during drainage, leading to a sharp drop in drainage efficiency; although some devices have added filter layers, they lack backflow protection design, allowing debris to easily re-enter the filtration system with the backflowing sewage, exacerbating the risk of clogging; in addition, the inspection ports of traditional devices are not well sealed, requiring complete disassembly for maintenance, which is cumbersome, time-consuming, and labor-intensive.

[0003] Chinese patent discloses a novel park drainage guiding structure (Publication No.: CN 212866246 U), which includes a supporting water trough. Several seepage holes are formed in the middle of both sides of the bottom surface of the supporting water trough. Several fixed spiked tubes are fixedly connected to the bottom surface of the outer wall of the supporting water trough near the seepage holes. The advantage of this invention is that it uses a supporting water trough with seepage holes in the middle of both sides of the bottom surface and fixed spiked tubes fixedly connected to one side of the bottom surface of the outer wall. However, this park drainage guiding structure is simple, lacks gradient filtration and backflow protection design, resulting in low drainage efficiency, easy clogging, and inconvenient maintenance. Therefore, a rapid drainage grid filtration device for recessed park surfaces is needed. Utility Model Content

[0004] The purpose of this invention is to address the problems of traditional ground drainage devices in the prior art, which suffer from low drainage efficiency, easy clogging, and inconvenient maintenance due to their simple structure, lack of gradient filtration and backflow protection design. Therefore, this invention proposes a rapid drainage grid filtration device for recessed ground in parks.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A rapid drainage grid filtration device for sunken park surfaces, comprising a ground layer, characterized in that: a filtration structure is provided inside the ground layer; a water intake module is provided on one side of the ground layer; and an inspection port is provided at the top of the ground layer. This achieves rapid drainage of sunken surfaces, preventing water accumulation; the integrated filtration structure intercepts debris, preventing pipe blockage; the water intake module facilitates rainwater collection or debris removal; and the inspection port provides a convenient access for equipment maintenance. Preferably, the top edge of the inspection port is provided with a triangular cover plate, and there are two corresponding triangular cover plates, each with a quincunx-shaped groove. The triangular cover plate structure allows for quick positioning of the opening position, facilitating maintenance operations; the quincunx-shaped groove design enhances the stability of the cover plate, preventing accidental sliding or misalignment; the symmetrically distributed cover plates improve the sealing of the inspection port, reducing the risk of foreign objects entering. Preferably, the filter structure includes a linear cover plate made of 304 stainless steel, with a linear drainage groove at its center. The linear drainage groove provides an efficient water flow channel, accelerating drainage; the 304 stainless steel material is corrosion-resistant and suitable for long-term outdoor use; the modular cover plate design facilitates individual replacement or cleaning.

[0006] Preferably, the linear cover plate has a honeycomb filter plate at its bottom, and the honeycomb filter plate has a U-shaped water guide channel at its bottom. The top edges of both sides of the U-shaped water guide channel have stepped steps with a height difference of 5-10mm. The honeycomb filter plate intercepts larger debris to prevent pipe blockage; the U-shaped water guide channel guides the water flow smoothly, reducing turbulence and noise; the stepped steps form a physical barrier to prevent debris or sewage from flowing back into the filter layer.

[0007] Preferably, the honeycomb filter plate has a pore size of 3-8mm and a porosity ≥60%, and is made of ABS engineering plastic or stainless steel by stamping to balance filtration accuracy and water flow efficiency. Reasonable pore size and porosity balance filtration efficiency and drainage speed, avoiding excessive clogging; ABS or stainless steel materials are suitable for different environmental needs (such as scenarios prioritizing cost or durability); the stamping process ensures structural strength and extends service life. Preferably, the water intake module includes a water intake cover plate with a water intake port. The water intake port facilitates direct collection of rainwater for irrigation or cleaning; the cover plate design prevents foreign objects from entering the water intake system, maintaining water quality cleanliness; the modular water intake module can be independently disassembled and maintained without affecting the overall drainage function.

[0008] The advantages of this utility model are: This application provides a rapid drainage grid filtration device for sunken ground in parks. Through the integrated design of the ground layer, filtration structure, water intake module, and inspection port, it achieves both efficient drainage and convenient maintenance. The filtration structure within the ground layer rapidly guides water flow through a linear drainage channel at the center of a linear cover plate. Combined with the gradient interception of the bottom honeycomb filter plate (honeycomb pore size 3-8mm, porosity ≥60%), it efficiently separates debris such as leaves and sediment while avoiding the clogging problems common in traditional single-layer filters. The stepped design on both sides of the U-shaped water guide channel forms a physical barrier, effectively preventing debris or sewage from flowing back into the filter layer, significantly improving the drainage system's anti-clogging capability. The independent water intake module makes rainwater collection or debris removal more convenient, allowing operation without disassembling the entire device. The double triangular cover plate at the top of the inspection port, combined with a quincunx-shaped slot, not only enables quick positioning and opening but also enhances the sealing of the inspection port, reducing the risk of foreign objects entering. In addition, the linear cover is made of 304 stainless steel, and the honeycomb filter plate can be made of ABS engineering plastic or stainless steel stamping, which takes into account both corrosion resistance and structural strength, and meets the needs of long-term outdoor use.

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 scope of protection of the present utility model. Example

[0016] Please see Figure 1-4 As shown, a rapid drainage grid filtration device for sunken areas in a park includes a ground layer 4. The device is characterized by: a filtration structure inside the ground layer 4; a water intake module on one side of the ground layer 4; and an inspection port on the top of the ground layer 4. This device enables rapid drainage of sunken areas, preventing water accumulation; the integrated filtration structure intercepts debris, preventing pipe blockage; the water intake module facilitates rainwater collection or debris removal; and the inspection port provides convenient access for equipment maintenance. In this embodiment, a triangular cover plate 2 is provided on the top edge of the inspection port. There are two triangular cover plates 2, which are arranged correspondingly. Each triangular cover plate 2 has a quincunx-shaped groove 1. The triangular cover plate 2 structure can quickly locate the opening position, which is convenient for maintenance operations. The quincunx-shaped groove 1 design enhances the stability of the cover plate and prevents accidental sliding or misalignment. The symmetrically distributed cover plates improve the sealing of the inspection port and reduce the risk of foreign objects entering. In this embodiment, the filter structure includes a linear cover plate 3, which is made of 304 stainless steel. A linear drainage groove 7 is located at the center of the linear cover plate 3. The linear drainage groove 7 provides an efficient water flow channel, accelerating drainage; the 304 stainless steel material is corrosion-resistant and suitable for long-term outdoor use; the modular cover plate design facilitates individual replacement or cleaning.

[0017] In this embodiment, the bottom of the linear cover plate 3 is provided with a honeycomb filter plate 9, and the bottom of the honeycomb filter plate 9 is provided with a U-shaped water guide channel 8. The top edges on both sides of the U-shaped water guide channel 8 are provided with stepped steps 10 with a height difference of 5-10mm. The honeycomb filter plate 9 intercepts larger debris to prevent pipe blockage; the U-shaped water guide channel 8 guides the water flow smoothly, reducing turbulence and noise; the stepped steps 10 form a physical barrier to prevent debris or sewage from flowing back into the filter layer.

[0018] In this embodiment, the honeycomb filter plate 9 has a pore size of 3-8mm and a porosity ≥60%, and is made of ABS engineering plastic or stainless steel by stamping to balance filtration accuracy and water flow efficiency. The reasonable pore size and porosity balance filtration efficiency and drainage speed, avoiding excessive clogging; ABS or stainless steel materials are suitable for different environmental needs (such as scenarios prioritizing cost or durability); the stamping process ensures structural strength and extends service life. In this embodiment, the water intake module includes a water intake cover 6, on which a water intake port 5 is provided. The water intake port 5 facilitates direct collection of rainwater for irrigation or cleaning; the cover design prevents foreign objects from entering the water intake system, maintaining water quality cleanliness; the modular water intake module can be independently disassembled and maintained without affecting the overall drainage function.

[0019] The implementation principle of this embodiment is as follows: After rainfall occurs on the sunken ground, rainwater first quickly collects through the linear drainage channel 7 in the center of the linear cover plate 3 of the ground layer 4. The channel design of the linear drainage channel 7 (with its width and depth adapted) can increase the water flow contact area, accelerate the initial drainage speed, and prevent the formation of surface water accumulation.

[0020] The initially collected rainwater flows into the honeycomb filter plate 9 at the bottom through the linear drainage channel 7. The honeycomb filter plate 9, with its honeycomb pore size (3-8mm) and high porosity (≥60%), forms a graded filtration system: larger debris (such as branches and leaves) is intercepted on the surface by the honeycomb pores, while smaller particles (such as silt) fall through the pores into the U-shaped water guide channel 8. The honeycomb plate, made of stainless steel or ABS material, combines strength and corrosion resistance, allowing for long-term stable operation. The rainwater filtered by the honeycomb plate enters the U-shaped water guide channel 8 and flows along the channel towards the water intake module. The stepped steps 10 (height difference 5-10mm) at the top of both sides of the U-shaped channel form a physical barrier: if a small amount of debris or sewage attempts to flow back due to turbulence, the stepped steps can prevent it from flowing back to the honeycomb filter plate, avoiding secondary pollution of the filter layer; at the same time, the arc-shaped bottom design of the U-shaped channel can slow down the water flow speed, further reducing the risk of debris deposition.

[0021] The filtered clean rainwater flows through the U-shaped water channel 8 to the water intake 5 of the water intake module, and can be directly used for park irrigation or cleaning systems. When it is necessary to clean up debris or perform maintenance, the double triangular cover 2 of the inspection port can be quickly opened through the quincunx-shaped slot 1 (the symmetrical design facilitates positioning) without damaging the ground structure; the independent cover design of the water intake module allows for individual disassembly and cleaning, avoiding the high cost of overall disassembly and assembly.
