Description

Technical Field

[0001] This utility model belongs to the field of courtyard drainage technology, and specifically relates to an anti-clogging drainage device for villa courtyards. Background Technology

[0002] As an outdoor space that combines landscape viewing and daily activities, the drainage system of a villa courtyard must simultaneously meet the dual requirements of reliability in preventing blockages and aesthetic appeal. In this scenario, fallen leaves, dead branches, tree roots, and a small amount of household waste are the main causes of drainage blockages. Existing technologies have developed two main solutions to prevent blockages, but both have significant shortcomings. The linear drainage system uses long, linearly opening drainage channels to directly intercept debris such as stones and large leaves, preventing them from entering the lower drainage pipes, aiming to reduce the risk of blockages. However, this solution is insufficient at intercepting small impurities, which can easily penetrate the linear openings: tree roots, leaf stalks, small pieces of dead branches, and other small materials can flow with the water through the linear openings into the lower pipes, accumulating over time and causing blockages on the inner walls of the pipes.

[0003] The maintenance of the lower pipes is costly and complicated: when the pipes are blocked, it is necessary to use professional equipment or dig up the yard to clean them. This not only consumes labor and equipment costs, but may also damage the yard paving and greenery. After repair, the landscape needs to be re-arranged, which further increases the maintenance costs and time costs.

[0004] The rectangular panel covering solution uses a rectangular cover with drainage holes at the drain outlet to allow water to flow into the pipes, while trapping leaves and debris on the cover surface for easy cleaning. Its core design principle is to simplify the debris removal process. However, the accumulation of debris detracts from the aesthetics of the courtyard: the trapped leaves and dead branches are directly exposed on the rectangular panel surface, and even a small amount can create a visual clash with the carefully designed landscape (such as lawns, flowers, and paving), compromising the overall cleanliness and aesthetics, and contradicting the original intention of the villa courtyard's landscape design.

[0005] Even in light rain, although the amount of debris intercepted is small, users still need to frequently check and clean the debris on the cover surface in a timely manner to avoid affecting the aesthetics, which increases the burden of daily maintenance. If not cleaned in time, a small amount of debris may also be blown by the wind to other areas of the yard, further expanding the cleaning scope. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-clogging drainage device for villa courtyards.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a drainage device for anti-clogging in villa courtyards, including an external mounting component, a circular filter element centrally disposed on the inner side of the external mounting component, and one end of the circular filter element forming an arc-shaped end. A connecting frame and a receiving frame, both located inside the external mounting component, are sequentially fitted on the surface of the circular filter element, with the connecting frame located at the end of the circular filter element surface away from the arc-shaped end, and the receiving frame located at the end of the circular filter element surface near the arc-shaped end. The receiving frame has an inner sleeve ring that is snapped on and installed in the center, and the inner sleeve ring is movably fitted onto the surface of the circular filter element.

[0008] Preferably, the socket frame is snapped together with the circular filter element, and two sliders are snapped together on both sides of the socket frame, with the ends of the two sliders near the receiving frame forming an inclined surface that is inclined toward the opposite side.

[0009] Preferably, a receiving cavity is formed between the receiving frame and the inner sleeve, and sliders are snapped onto both sides of the receiving frame, with sliders located on one side of the inclined surface.

[0010] Preferably, both ends of the two sliders are formed with inclined surfaces two that are inclined toward the opposite surface, and the inclined surface two of the slider two near the end of the slider one is in contact with the inclined surface one for use.

[0011] Preferably, the inner side of the receiving frame is provided with symmetrically arranged sliding grooves, and both slider one and slider two are used in sliding cooperation with the sliding grooves.

[0012] Preferably, a pull ring is snapped onto the inclined surface of the second slider away from the first slider, and the two pull rings are designed symmetrically.

[0013] Preferably, each of the four circumferential surfaces on the inner side of the outer mounting component has an embedded cavity, the height of the embedded cavity is less than the height of the receiving frame, and the inner side of the embedded cavity near the socket frame has an inclined surface.

[0014] Preferably, the end of the inner ring near the arc-shaped end is designed to be inclined, and the inclination angles of the inner ring end, inclined surface one, inclined surface two, and inclined surface three are all designed to be uniform.

[0015] In summary, this utility model has the following beneficial effects: 1. Addressing different impact conditions of rainwater carrying debris, the external mounting component utilizes an arc-shaped end structure to smoothly guide the debris. When the impact force of rainwater on debris is significant, the debris is carried by the water flow to the arc-shaped end of the external mounting component. Because the end of the arc-shaped structure has no sharp edges or protrusions, it avoids jamming or obstruction of the debris, ensuring its continuous movement with the water flow. When the impact force of rainwater on debris is less, the debris, aided by its own weight and the weak water flow, can naturally slide down the inner wall of the external mounting component and eventually fall into the receiving frame for storage. This design adapts to the debris handling needs under different water flow impact intensities, effectively ensuring smooth flow of debris and its direct placement into the designated storage component under various conditions. 2. Under normal operating conditions, debris is collected into the receiving cavity of the receiving frame under the combined action of its own weight and the impact force of rainwater. At this time, rainwater can penetrate the mesh frame structure of the receiving frame, enter the inside of the socket frame, and then be collected and discharged by the external drainage pipe after passing through the socket frame, completing the normal rainwater discharge process. However, when the debris accumulates to a certain threshold inside the receiving frame, the debris layer causes a significant reduction in the infiltration efficiency of rainwater at the mesh frame of the receiving frame. At this time, the rainwater will form two diversion paths along the outer wall of the receiving frame and the outer wall of the inner ring. The multi-path rainwater flow structure can specifically solve the problem of decreased infiltration efficiency caused by debris accumulation, effectively ensuring the smooth flow of rainwater under the condition of excessive debris accumulation, and avoiding the risk of local water accumulation or blockage caused by rainwater retention. 3. Rainwater flowing along the outer wall of the receiving frame enters the embedded cavity, where it is guided and converged by the pre-set inclined surface three at the bottom of the embedded cavity. The rainwater can flow smoothly towards the socket frame along the slope of inclined surface three, eventually flowing into the inner side of the socket frame and being discharged through the external pipe. This path can improve the flow rate of rainwater in the area around the receiving frame, and also shorten the contact and retention time between debris and rainwater by accelerating rainwater discharge. 4. The inner diameter of the mesh openings of the sleeve frame and the circular filter element in this device is smaller than that of the mesh openings of the receiving frame, forming a filtration stage of coarse and fine filtration. The receiving frame, as the primary filtration component, mainly intercepts large debris such as leaves and twigs; the sleeve frame and the circular filter element, as the secondary filtration component, further intercept finer impurities not caught by the receiving frame, such as silt particles and small fibers, preventing these tiny impurities from entering the external drainage pipes with rainwater. This multi-stage filtration structure reduces the total amount of impurities entering the pipes at the source, effectively reducing the risk of siltation on the inner walls of the pipes, ensuring the long-term stable operation of the external drainage pipes, extending the pipe maintenance cycle, and reducing the cost and workload of subsequent pipe dredging. 5. When cleaning the device is required, the operator can directly insert their fingers into the inside of the pull ring and press them against the inner wall of the slide groove, then lift the pull ring upwards along the extension direction of the slide groove to remove the receiving frame. The circular filter element can then be directly removed from the receiving frame. The pull ring's wall-mounted design has two advantages: firstly, it minimizes the space occupied in the area used to receive leaves and other debris, ensuring effective storage capacity; secondly, it avoids the difficulty of grasping the pull ring caused by leaves and other debris covering it, ensuring good operability even in scenarios with accumulated leaves. 6. During the removal of the receiving frame and the socket frame from the external mounting component, the inclined surface one of slider one and the inclined surface two of slider two will simultaneously clean and scrape away impurities from the inner wall of the chute as the receiving frame and the socket frame move. This inclined structure design can guide impurities to tilt towards the inside of the receiving frame or the socket frame, providing a self-cleaning function for the long-term service of the external mounting component, and effectively ensuring that slider one and slider two can accurately return to the preset position during reinstallation.

Detailed Implementation

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example

[0020] refer to Figures 1-5 A drainage device for villa courtyards that prevents blockage includes an external mounting component 100. A circular filter element 200 is centrally located on the inner side of the external mounting component 100, and one end of the circular filter element 200 forms an arc-shaped end 201. A connecting frame 300 and a receiving frame 500, both located inside the external mounting component 100, are sequentially fitted on the surface of the circular filter element 200. The connecting frame 300 is located at the end of the circular filter element 200 away from the arc-shaped end 201, and the receiving frame 500 is located at the end of the circular filter element 200 close to the arc-shaped end 201. An inner collar 501 for snap-fit ​​installation is provided in the center of the inner side of the receiving frame 500, and the inner collar 501 is movably sleeved on the surface of the circular filter element 200.

[0021] Specifically, for different impact conditions of rainwater carrying debris, the external mounting component 100 uses an arc-shaped end 201 structure to smoothly guide the debris. When the impact force of rainwater on debris is large, the debris is impacted by the water flow to the arc-shaped end 201 of the external mounting component 100. Because the end of the arc-shaped end 201 adopts an arc-shaped structure design, without sharp edges or protrusions, it can avoid jamming or obstructing the debris, ensuring that the debris continues to move with the water flow. When the impact force of rainwater on debris is small, the debris can slide naturally along the inner wall of the external mounting component 100 under its own weight and with the assistance of the weak water flow, and finally fall into the receiving frame 500 for storage. This design adapts to the debris handling needs under different water flow impact intensities, effectively ensuring that debris can flow smoothly and be guided to the designated storage component under various working conditions.

[0022] The socket frame 300 is snapped into the circular filter element 200. Slider 1 301 is snapped into both sides of the socket frame 300. The ends of the two sliders 1 301 near the receiving frame 500 form inclined surfaces 1 302 that are inclined towards the opposite surface. A receiving cavity 502 is formed between the receiving frame 500 and the inner ring 501. Slider 2 600 is snapped into both sides of the receiving frame 500. Slider 2 600 is located on one side of the inclined surface 1 302. The ends of the two sliders 2 600 form inclined surfaces 2 601 that are inclined towards the opposite surface. The inclined surface 2 601 of slider 2 600 near the end of slider 1 301 contacts and cooperates with the inclined surface 1 302. The inner side of the receiving frame 500 has symmetrically arranged sliding grooves 400. Both slider 1 301 and slider 2 600 slide and cooperate with the sliding grooves 400.

[0023] Specifically, during the assembly process of the socket frame 300 and the inner side of the outer mounting part 100, the pre-positioning between the socket frame 300 and the outer mounting part 100 can be initially completed by the matching and snapping of the slider 301 and the slide groove 400; when the end of the slider 301 and the end of the slide groove 400 are locked in a limiting snapping, the longitudinal positioning of the socket frame 300 inside the outer mounting part 100 can be achieved. This dual positioning structure provides a reliable guarantee for the stable placement of the socket frame 300 inside the outer mounting part 100.

[0024] During the assembly process of the receiving frame 500 and the inner side of the outer mounting part 100, the snap-fit ​​positioning method of the second slider 600 and the slide groove 400 is initially consistent with the positioning logic of the first slider 301. At the same time, when the inclined surface 601 of the receiving frame 500 and the inclined surface 302 of the sleeve frame 300 make contact and fit, the first slider 301 can provide stable support for the second slider 600, further improving the structural stability of the receiving frame 500 after assembly.

[0025] A pull ring 700 is snapped onto the inclined surface 601 of slider 2 600, which is away from slider 1 301, and the two pull rings 700 are designed symmetrically.

[0026] Specifically, the pull ring 700 is designed to facilitate the movement of the slider 600 and the receiving frame 500. When the receiving frame 500 is assembled inside the outer mounting part 100, one side of the pull ring 700 is tightly fitted against the inner wall of the slide groove 400. When the operator needs to pick up or put down the receiving frame 500, he / she can directly insert his / her finger into the inside of the pull ring 700 and fit it against the inner wall of the slide groove 400, and lift the pull ring 700 upward along the extension direction of the slide groove 400 to pick up or put down the receiving frame 500.

[0027] This wall-mounted design has two advantages: on the one hand, it can minimize the space occupied in the area used to receive leaves and other debris, ensuring effective storage capacity; on the other hand, it can avoid the problem of difficult operation and grasping caused by leaves and other debris covering the pull ring 700, ensuring that the pull ring 700 still has good operability in the scenario of accumulated leaves.

[0028] The four circumferential surfaces of the outer mounting component 100 are provided with embedded cavities 800. The height of the embedded cavity 800 is less than the height of the receiving frame 500. The inner side of the embedded cavity 800 near the socket frame 300 forms an inclined surface 3 801. The end of the inner ring 501 near the arc end 201 is designed to be inclined. The inclination angles of the end of the inner ring 501, the inclined surface 1 302, the inclined surface 2 601 and the inclined surface 3 801 are all designed to be uniform.

[0029] Specifically, in the actual application of the external mounting component 100, its circular filter element 200, inner ring 501, receiving frame 500, and socket frame 300 all adopt a mesh frame structure that can filter impurities, possessing basic impurity interception functions. Among them, the inner cavity 800 of the receiving frame 500 is mainly used to support and collect larger debris such as leaves and dead branches; in this scenario, rainwater can pass through the mesh structure of the receiving frame 500, with some seeping into the inner cavity 800 from the outer wall of the receiving frame 500, and the other part directly seeping into the debris and passing through the receiving frame 500 under the action of gravity.

[0030] The guiding design of the inclined surface 801 allows rainwater in the embedded cavity 800 to converge towards the socket frame 300 along the slope of the inclined surface 801, eventually flowing smoothly into the inner side of the socket frame 300. This design effectively improves the infiltration efficiency and flow rate of rainwater within the receiving frame 500, and reduces the residence time of debris within the receiving frame 500 by accelerating rainwater discharge, thereby enhancing the overall anti-clogging performance of the device. Furthermore, the uniform design of the inclined surface ensures the consistency of the rainwater diversion rate.

[0031] The working principle of this utility model is as follows: In the actual application of this drainage device, the external mounting component 100 is embedded in the ground, and its bottom is received and collected by the drainage pipe to form a drainage channel. The courtyard ground has a preset slope, and rainwater can flow and collect towards the inside of the external mounting component 100 along the slope direction of the ground. This installation method is a conventional installation method and belongs to the known technology in the field, so it will not be described in detail here.

[0032] To address different impact conditions caused by rainwater carrying debris, the external mounting component 100 utilizes an arc-shaped end 201 structure to smoothly guide the debris. When the impact force of rainwater on debris is significant, the debris is carried by the water flow to the arc-shaped end 201 of the external mounting component 100. Because the end of the arc-shaped end 201 is designed with an arc shape, without sharp edges or protrusions, it avoids jamming or obstructing the debris, ensuring its continuous movement with the water flow. When the impact force of rainwater on debris is relatively small, the debris, aided by its own weight and the weak water flow, can naturally slide down the inner wall of the external mounting component 100 and eventually fall into the receiving frame 500 for storage.

[0033] Under normal operating conditions, debris is collected into the receiving cavity 502 of the receiving frame 500 under the combined action of its own gravity and the impact force of rainwater. At this time, rainwater can penetrate the mesh frame structure of the receiving frame 500, enter the interior of the socket frame 300, and then be collected and discharged by the external drainage pipe after passing through the socket frame 300, completing the conventional rainwater discharge process. However, when debris accumulates to a certain threshold inside the receiving frame 500, the debris layer will hinder rainwater infiltration, resulting in a significant reduction in the infiltration efficiency of rainwater at the mesh frame of the receiving frame 500. At this time, the rainwater will form two diversion paths along the outer wall of the receiving frame 500 and the outer wall of the inner ring 501: Rainwater flowing along the outer wall of the receiving frame 500 enters the inner cavity 800, where it is guided and converged by the inclined surface 3 801 at the bottom of the inner cavity 800. The rainwater flows smoothly towards the socket 300 along the slope of the inclined surface 3 801, eventually flowing into the inner side of the socket 300 and being discharged through an external pipe. This path increases the flow rate of rainwater around the receiving frame 500 and, by accelerating rainwater discharge, shortens the contact time between debris and rainwater, further enhancing the device's anti-clogging performance. Rainwater flowing along the outer wall of the inner ring 501 directly enters the circular filter element 200. After being filtered by the circular filter element 200, it can be directly connected to the discharge stage without secondary guidance, simplifying the rainwater discharge path while ensuring rapid discharge.

[0034] Meanwhile, the inner diameter of the mesh of the socket frame 300 and the circular filter element 200 is smaller than that of the receiving frame 500. The receiving frame 500, as a primary filtration component, mainly intercepts large debris such as leaves and twigs. The socket frame 300 and the circular filter element 200, as secondary filtration components, can further intercept fine impurities that the receiving frame 500 fails to intercept, such as mud and sand particles and small fibers, thus preventing such tiny impurities from entering the external drainage pipe with rainwater.

[0035] When the device needs to be cleaned, the operator can directly insert their fingers into the inside of the pull ring 700 and press them against the inner wall of the slide groove 400, and lift the pull ring 700 upwards along the extension direction of the slide groove 400 to remove and place the receiving frame 500. Then, the circular filter element 200 can be directly removed and the socket frame 300 can be taken out. At the same time, during the process of removing the receiving frame 500 and the socket frame 300 from the outer mounting part 100, the inclined surface 302 of the slider 1 301 and the inclined surface 601 of the slider 2 600 will simultaneously clean and scrape off the impurities on the inner wall of the slide groove 400 as the receiving frame 500 and the socket frame 300 move.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
