Description

Technical Field

[0001] This utility model relates to the field of municipal drainage, and in particular to anti-clogging drainage ditches. Background Technology

[0002] Drainage ditches are structures used to collect and guide water flow, designed to prevent water from accumulating in specific areas, thereby protecting soil, improving safety, and improving water quality. Drainage ditches are mainly used for surface drainage and are usually set up along roads, buildings, or other ground structures to quickly drain surface water such as rainwater and wastewater.

[0003] In existing drainage ditches, solid dirt and impurities from the road can easily enter the drainage ditches under the impact of water flow, causing blockages and preventing water from flowing out, resulting in water accumulation on the road.

[0004] Therefore, to address the problem that solid dirt and impurities on the aforementioned roads can easily enter the drainage ditches and cause blockages due to the impact of water flow, an anti-blockage drainage ditch can be designed. By designing the drainage ditch in layers, dirt entering the drainage ditch is intercepted by the upper layer, while water flows out from the lower layer. When the water volume is large, the impact force of the large water flow will drive the dirt out from the upper layer. Utility Model Content

[0005] To overcome the problem that solid dirt and impurities on the road can easily enter the drainage ditches during the drainage process, causing blockages and preventing water from flowing out, resulting in water accumulation on the road.

[0006] The technical solution of this utility model is as follows: a drainage ditch for preventing blockage, including a U-shaped drainage ditch, a U-shaped anti-blockage frame and a water tank cover; the U-shaped drainage ditch is provided with a U-shaped anti-blockage frame inside to prevent drainage blockage, and a primary drainage trough is provided between the U-shaped drainage ditch and the U-shaped anti-blockage frame to ensure normal water flow; a water tank cover is installed at the upper end of the U-shaped drainage ditch to prevent clumps of dirt from entering the drainage ditch; a secondary drainage trough is provided inside the U-shaped anti-blockage frame, and multiple sets of strip-shaped seepage holes are evenly provided at the bottom of the secondary drainage trough; the primary drainage trough and the secondary drainage trough are connected through multiple sets of strip-shaped seepage holes.

[0007] Preferably, this application combines a U-shaped drainage channel with a U-shaped anti-clogging frame, so that after the water flows into the U-shaped drainage channel, the solid sediments in the water are intercepted by the U-shaped anti-clogging frame in the secondary drainage channel, while the water flows through multiple sets of strip-shaped seepage holes at the bottom of the secondary drainage channel to the primary drainage channel for normal drainage. When the drainage volume is large, the water seeps from the primary drainage channel to the secondary drainage channel, providing buoyancy to the solid sediments while the impact force of the large water flow washes away the solid sediments.

[0008] Preferably, support bars are installed on both sides of the outer end of the U-shaped drainage channel, and mounting grooves for installing water tank covers are opened on the upper ends of both sides of the U-shaped drainage channel. Multiple sets of mounting holes are linearly opened inside the mounting grooves.

[0009] Preferably, multiple sets of corresponding mounting holes are linearly opened on both sides of the sink cover, and multiple sets of strip-shaped drainage holes are evenly opened on the surface of the sink cover.

[0010] Preferably, the lower ends of the multiple sets of strip-shaped drainage holes are provided with water-guiding chamfers on both sides.

[0011] Preferably, mounting slots are provided at the upper edges of both sides of the primary drainage channel, and limit strips are installed on both sides of the opening of the mounting slots.

[0012] As a preferred option, mounting strips are installed on the upper ends of both sides of the U-shaped anti-blocking bracket, and the mounting strips match and engage with the mounting slots.

[0013] Preferably, an inner connecting groove is provided on the inner side of one end of the U-shaped drainage channel, and an outer connecting groove is provided on the outer side of the other end of the U-shaped drainage channel, with the inner connecting groove and the outer connecting groove being matched and configured to match each other.

[0014] The beneficial effects of this utility model are as follows: Compared with the drainage ditches currently on the market, solid dirt and impurities on the road are easily drawn into the drainage ditches by the impact of water flow, causing blockages. This application combines a U-shaped drainage ditch with a U-shaped anti-blocking frame, so that after the water flows into the U-shaped drainage ditch, the solid sediments in the water are intercepted by the U-shaped anti-blocking frame in the secondary drainage channel, while the water flows through multiple sets of strip-shaped seepage holes at the bottom of the secondary drainage channel to the primary drainage channel for normal drainage. When the drainage volume is large, the water seeps from the primary drainage channel to the secondary drainage channel, providing buoyancy to the solid sediments while the impact force of the large water flow washes away the solid sediments. Through this vertical diversion method, the problem of solid dirt and impurities on the road easily clogging the drainage ditches is effectively solved. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of an anti-clogging drainage ditch, including a U-shaped drainage ditch 1, a U-shaped anti-clogging frame 2, and a water tank cover 4; the U-shaped drainage ditch 1 is provided with a U-shaped anti-clogging frame 2 to prevent drainage blockage, and a primary drainage trough 3 is provided between the U-shaped drainage ditch 1 and the U-shaped anti-clogging frame 2 to ensure normal water flow; a water tank cover 4 is installed at the upper end of the U-shaped drainage ditch 1 to prevent clumps of dirt from entering the drainage ditch; a secondary drainage trough 13 is provided inside the U-shaped anti-clogging frame 2, and multiple sets of strip-shaped seepage holes 14 are evenly provided at the bottom of the secondary drainage trough 13; the primary drainage trough 3 and the secondary drainage trough 13 are connected through the multiple sets of strip-shaped seepage holes 14.

[0022] Please see Figures 1-2 In this embodiment, an inner connecting groove 11 is provided on the inner side of one end of the U-shaped drainage ditch 1, and an outer connecting groove 10 is provided on the outer side of the other end of the U-shaped drainage ditch 1. The inner connecting groove 11 and the outer connecting groove 10 are matched and set together. By combining the inner connecting groove 11 and the outer connecting groove 10, when laying the drainage ditch, the workers can connect and lock multiple U-shaped drainage ditches 1 in sequence through the inner connecting groove 11 and the outer connecting groove 10 to complete the laying. Support strips 5 are installed on both sides of the outer end of the U-shaped drainage ditch 1. Mounting grooves 6 for mounting the water tank cover plate 4 are opened on both sides of the upper end of the U-shaped drainage ditch 1. Multiple sets of mounting holes 7 are linearly opened inside the mounting grooves 6. By means of the support strips 5, when laying the drainage ditch, after the workers put the U-shaped drainage ditch 1 into the pre-dug trench, the support strips 5 on both sides of the outer end of the U-shaped drainage ditch 1 can support and fix the U-shaped drainage ditch 1.

[0023] Please see Figures 2-3In this embodiment, mounting slots 8 are provided on the upper edges of both sides of the primary drainage ditch 3. Limiting strips 9 are installed on both sides of the opening of the mounting slots 8. Mounting strips 12 are installed on the upper ends of both sides of the U-shaped anti-blocking frame 2. The mounting strips 12 match and engage with the mounting slots 8. Usually, the mounting strips 12 and the mounting slots 8 are combined so that when assembling the drainage ditch, the workers can install the U-shaped anti-blocking frame 2 by engaging the mounting strips 12 on both sides along the mounting slots 8, and the limiting strips 9 prevent the mounting strips 12 from detaching from the mounting slots 8.

[0024] Please see Figures 3-4 In this embodiment, multiple sets of strip holes 15 corresponding to mounting holes 7 are linearly opened on both sides of the sink cover plate 4. Multiple sets of strip drainage holes 16 are evenly opened on the surface of the sink cover plate 4. By combining the strip holes 15 with the mounting holes 7, the operator can pass the bolts through the strip holes 15 and tighten them into the mounting holes 7 to install the sink cover plate 4 at the upper end of the U-shaped drainage channel 1, preventing larger solid dirt from entering the drainage channel. Water-guiding chamfers 17 are opened on both sides of the lower end of the multiple sets of strip drainage holes 16. By combining the strip drainage holes 16 with the water-guiding chamfers 17, smaller solid dirt in the water flow will not clog the drainage holes during drainage, which helps to reduce the accumulation of debris at the drainage holes, reduce the risk of clogging, and improve the durability of the sink.

[0025] During the work, after the workers put the U-shaped drainage channel 1 into the pre-dug trench, the support strips 5 on both sides of the outer end of the U-shaped drainage channel 1 can support and fix the U-shaped drainage channel 1. At the same time, the workers can connect and lock multiple U-shaped drainage channels 1 in sequence through the inner docking groove 11 and the outer docking groove 10 to complete the laying.

[0026] When assembling the drainage ditch, the workers can install the U-shaped anti-blocking bracket 2 by engaging the mounting clips 12 on both sides along the mounting slots 8, and prevent the mounting clips 12 from detaching from the mounting slots 8 by the limiting strips 9. Then, the bracket is combined with the mounting hole 7 through the strip hole 15, so that the workers can pass the bolt through the strip hole 15 and tighten it into the mounting hole 7. The water tank cover plate 4 is then installed at the upper end of the U-shaped drainage ditch 1 to prevent large solid dirt from entering the drainage ditch.

[0027] Through the above steps, this application combines a U-shaped drainage channel 1 with a U-shaped anti-blocking frame 2, so that after the water flows into the U-shaped drainage channel 1, the solid sediment in the water is intercepted by the U-shaped anti-blocking frame 2 and trapped in the secondary drainage trough 13. The water then flows through multiple sets of strip-shaped seepage holes 14 at the bottom of the secondary drainage trough 13 to the primary drainage trough 3 for normal drainage. When the drainage volume is large, the water seeps from the primary drainage trough 3 to the secondary drainage trough 13, providing buoyancy to the solid sediment while the impact force of the large water flow washes away the solid sediment. Through this method of splitting the flow, the problem of solid dirt and impurities on the road easily clogging the drainage ditch is effectively solved.
