Description

Technical Field

[0001] This utility model relates to the field of garden drainage anti-blocking technology, specifically a garden ditch anti-blocking device. Background Technology

[0002] A garden refers to a beautiful natural environment and recreational space created within a specific area using engineering techniques and artistic methods, such as modifying the terrain, planting trees and flowers, constructing buildings, and arranging garden paths. In garden construction, the garden's water supply and drainage system is a crucial component ensuring its drainage capacity. It mainly includes surface drainage ditches and underground pipe networks. Besides its daily sewage discharge function, it also plays a role in promptly draining rainwater, reducing the likelihood of flooding, and thus ensuring the integrity and aesthetics of surface facilities and green spaces.

[0003] In gardens, open drainage channels are prone to blockages caused by debris such as fallen leaves and branches, which are difficult to clean. Therefore, culverts or covered channels are more suitable to prevent debris from entering. To allow surface water into the channels, drainage wells can be installed at intervals along the channels. Anti-clogging devices can be installed at the drainage wells to filter and collect any debris entering, effectively preventing blockages. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a garden ditch anti-clogging device. The technical solution adopted is to design a sludge collection well, with an inlet and an outlet respectively opened in the middle of the side wall of the sludge collection well. A pressing groove is opened on the inner edge of the top opening. A ditch inlet connection end is fixedly connected to the outer wall of the sludge collection well at the position corresponding to the inlet, and a ditch outlet connection end is fixedly connected at the position corresponding to the outlet. The ditch inlet connection end is connected to the upstream section of the ditch, and the ditch outlet connection end is connected to the downstream section of the ditch. The inlet is higher than the outlet, thereby ensuring that the water flowing into the sludge collection well from the ditch inlet connection end can flow smoothly out from the outlet and into the ditch outlet connection end, and backflow is not likely to occur. The top opening of the sewage collection well is covered with a well cover. The well cover has a water leakage groove in the middle and a cover groove on the lower circumferential edge. The cover groove snaps onto the edge of the upper opening of the sewage collection well, allowing water to flow into the sewage collection well from the water leakage groove. The elongated groove design facilitates water flow and avoids blockage. The bottom of the inner cavity of the sludge collection well is placed with a lower sludge collection cage. The bottom of the lower sludge collection cage is a sedimentation box. The upper edge of the sedimentation box is lower than the bottom of the water inlet. A debris-blocking cage is fixedly connected to the upper part of the sedimentation box. The debris-blocking cage has a sludge inlet, which corresponds to the water inlet. Water and debris flowing in the ditch enter the sludge collection well through the ditch inlet and the water inlet. They will directly enter the lower sludge collection cage through the debris-blocking cage. Heavier debris such as mud and sand will sink into the sedimentation box. The water flows out from the outlet after being filtered by the debris-blocking cage. Larger floating objects such as dead branches and leaves that are prone to clogging will be intercepted by the debris-blocking cage to prevent them from entering the ditch and causing blockage. An upper sludge collection cage is installed above the lower sludge collection cage. The bottom of the upper sludge collection cage presses against the upper end of the lower sludge collection cage. The upper edge of the upper sludge collection cage is bent outward to form a hook-shaped bend, which hooks onto the pressing groove. The manhole cover is placed over the upper sludge collection cage. Drainage holes are evenly distributed on the bottom plate of the upper sludge collection cage. Debris entering through the drainage slots of the manhole cover is intercepted and collected by the upper sludge collection cage. Water carrying silt and other debris enters the lower sludge collection cage through the drainage holes, while heavier silt and other debris are deposited in the sedimentation box.

[0005] As a preferred embodiment of this utility model, a positioning groove is provided on the inner side of the sludge collection well, and a positioning block is fixedly connected to the outer side of the sedimentation box. Only when the positioning block is slidably inserted into the positioning groove can the lower sludge collection cage be placed into the sludge collection well, thereby ensuring that the position orientation of the lower sludge collection cage remains unchanged after it is placed in, so that the sludge inlet corresponds to the water inlet.

[0006] As a preferred embodiment of this utility model, both the lower and upper sludge collection cages are made of stainless steel, which is more robust and corrosion-resistant, and allows for easy removal and emptying after the cages are full of debris.

[0007] The beneficial effects of this utility model are as follows: This utility model provides a sludge collection well for ditches, facilitating the flow of surface water into the ditch for drainage. The upper sludge cage inside the well collects debris flowing in from the well cover, while the lower sludge cage further filters the water flowing through the ditch. Heavier debris such as silt is collected in a sedimentation box, and larger floating objects that could easily cause blockages are intercepted. Multiple sludge collection wells can be installed along the ditch, depending on its length and drainage location, not only meeting drainage needs but also filtering the water multiple times to prevent debris accumulation and blockages. Both the upper and lower sludge cages are snap-fitted into the sludge collection wells for easy removal and cleaning. The entire device has a simple structure, is easy to install, provides good debris removal and anti-blockage effects, is easy to maintain and manage, and has low application costs.

[0015] Example 1

[0016] like Figures 1 to 6As shown, this utility model discloses a garden ditch anti-clogging device, which includes a sludge collection well 1. An inlet 101 and an outlet 102 are respectively provided in the middle of the side wall of the sludge collection well 1. A pressing groove 103 is provided on the inner edge of the top opening. A positioning groove 104 is provided on the inner side of the sludge collection well 1. A ditch inlet connection end 3 is fixedly connected to the outer wall of the sludge collection well 1 at a position corresponding to the inlet 101, and a ditch outlet connection end 4 is fixedly connected to the outer wall of the sludge collection well 1 at a position corresponding to the outlet 102. The ditch inlet connection end 3 is connected to the upstream section of the ditch, and the ditch outlet connection end 4 is connected to the downstream section of the ditch. The inlet 101 is higher than the outlet 102, thereby ensuring that water flowing into the sludge collection well 1 from the ditch inlet connection end 3 can flow smoothly out of the outlet 102 and into the ditch outlet connection end 4, preventing backflow. The top opening of the sewage collection well 1 is covered by a well cover 2. The well cover 2 has a water leakage groove 201 in the middle and a cover groove 202 on the lower circumferential edge. The cover groove 202 snaps onto the upper opening edge of the sewage collection well 1. Water can flow into the sewage collection well 1 from the water leakage groove 201. The long groove design facilitates water flow and avoids blockage.

[0017] The lower sludge cage 5 is placed at the bottom of the inner cavity of the sludge collection well 1. The bottom of the lower sludge cage 5 is a sedimentation box 501. The upper edge of the sedimentation box 501 is lower than the bottom of the inlet 101. A sludge-blocking cage body 502 is fixedly connected to the upper part of the sedimentation box 501. A sludge inlet 503 is opened on the sludge-blocking cage body 502. A positioning block 504 is fixedly connected to the outer side of the sedimentation box 501. Only when the positioning block 504 is slidably inserted into the positioning groove 104 can the lower sludge cage 5 be placed into the sludge collection well 1, thereby ensuring that the lower sludge cage 5 is placed in the sludge collection well 1. After the sludge collection cage 5 is placed, its position and orientation remain unchanged, so that the sludge inlet 503 corresponds to the water inlet 101. Water and debris flowing in the ditch enter the sludge collection well 1 through the ditch inlet connection end 3 and the water inlet 101, and will directly enter the lower sludge collection cage 5 through the sludge inlet 503. Heavier debris such as mud and sand will sink into the sedimentation box 501. The water flows through the sludge trap body 502 for filtration and flows out from the water outlet 102. Larger floating objects such as dead branches and leaves that are prone to clogging will be intercepted by the sludge trap body 502 to prevent them from entering the ditch and causing blockage.

[0018] An upper sludge collection cage 6 is positioned above the lower sludge collection cage 5. The bottom of the upper sludge collection cage 6 presses against the upper end of the lower sludge collection cage 5. The upper edge of the upper sludge collection cage 6 is bent outward to form a hook bend 601, which hooks onto the pressing groove 103. The manhole cover 2 covers the upper sludge collection cage 6. Drainage holes 602 are evenly distributed on the bottom plate of the upper sludge collection cage 6. Debris entering through the drainage slot 201 of the manhole cover 2 is intercepted and collected by the upper sludge collection cage 6. Water carrying mud and sand enters the lower sludge collection cage 5 through the drainage holes 602. Heavier mud and sand will settle in the sedimentation box 501. Both the lower sludge collection cage 5 and the upper sludge collection cage 6 are made of stainless steel, making them more robust and corrosion-resistant. After being filled with debris, they can be easily pulled out for dumping and cleaning. During the routine maintenance of garden ditches, it is only necessary to inspect the sewage collection well 1. If there is too much debris collected in the lower sewage collection cage 5 and the upper sewage collection cage 6, it can be removed and cleaned directly. There is no need to inspect or clean the entire ditch, which effectively reduces the workload of preventing clogging and cleaning the ditch.
