Abstract
Description
Technical Field
[0001] This utility model relates to the field of road drainage technology, and in particular to a drainage structure. Background Technology
[0002] Road drainage typically utilizes the cross and longitudinal slopes of the road surface to quickly guide rainwater into roadside drainage structures. Currently, the most common drainage structure is a drainage ditch covered with a mesh cover. However, over time, debris such as stones, litter, and leaves from the road surface can enter the drainage ditch through the mesh cover. In sections with low rainfall and narrow drainage channels, debris can easily accumulate, affecting drainage efficiency.
[0003] The related technology proposes a highway drainage ditch, including a drainage frame, a grid cover, and a filter assembly. The grid cover is detachably installed on the top of the drainage frame. The filter assembly includes a connecting plate and two filter plates inclined inside the drainage frame. The addition of filter plates on top of the grid cover enables secondary filtration of waste entering the drainage frame, reducing the risk of drainage interruption.
[0004] However, in the aforementioned highway drainage ditches, fixing blocks are fixedly installed on both sides of the bottom of the grating plate. The fixing blocks are engaged with the fixing grooves opened on the upper part of the drainage frame. When the impact of rainwater is strong or when heavy objects crush the drainage ditch, the connection between the grating plate and the drainage frame may become loose or shift, resulting in poor connection strength and overall integrity of the drainage ditch. Utility Model Content
[0005] The purpose of this utility model is to provide a drainage structure that can improve the connection strength and overall integrity of the drainage structure components, reduce the risk of blockage in the drainage channel, and ensure the smooth progress of the drainage process.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] This utility model proposes a drainage structure, including:
[0008] The tank has drainage channels along its height, with the openings of the drainage channels facing upwards.
[0009] A drainage auxiliary support includes an overlapping member, a connecting member, and a flow guide member that are connected in sequence and are all arranged at an angle. The overlapping member overlaps the top surface of the trough, the connecting member abuts against the wall of the drainage trough, and at least a portion of the flow guide member is arranged at an angle with the bottom of the drainage trough and has a plurality of first drainage holes, all of which are connected to the drainage trough.
[0010] A cover plate is positioned above the drainage auxiliary support and is detachably connected to the overlapping component. The cover plate has multiple second drainage holes, all of which are connected to the first drainage hole. The diameter of the second drainage hole is larger than that of the first drainage hole.
[0011] Optionally, the guide member includes a first guide section and a second guide section connected to each other. The first guide section and the second guide section are both set at an angle to the bottom of the drainage trough and are each provided with a plurality of first drainage holes. A connector is connected to each side of the first guide section and the second guide section that are far apart from each other.
[0012] Specifically, the guide also includes a support, the first guide is connected to the second guide through the support, and the support is in contact with the bottom surface of the cover plate.
[0013] Optionally, the drainage auxiliary support also includes a support member, which is disposed at one end of the guide member near the wall of the drainage trough and parallel to the bottom of the drainage trough. One end of the support member is connected to the guide member, and the other end is connected to the connector.
[0014] For example, the top of the groove has an installation groove along its length, the connecting piece overlaps the bottom of the installation groove, the cover plate abuts against the groove wall of the installation groove and the top surface of the cover plate is flush with the groove opening of the installation groove.
[0015] Specifically, the drainage structure includes a seal that is sandwiched between the overlap and the bottom of the mounting groove.
[0016] Optionally, one of the overlapping member and the cover plate has a connecting hole, and the other has a connecting protrusion that engages with the connecting hole.
[0017] Optionally, the drainage structure also includes a handle, which is detachably mounted on the top surface of the cover.
[0018] The beneficial effects of this utility model are:
[0019] This invention proposes a drainage structure. The trough has a drainage channel, and an overlapping member overlaps the top surface of the trough and is detachably connected to the cover plate. A connecting member abuts against the wall of the drainage channel. Compared to the single snap-fit method between the drainage frame and the cover plate in the prior art, the connection strength and overall integrity between the trough, drainage auxiliary support, and cover plate in the proposed drainage structure are improved. The cover plate has multiple second drainage holes, and the guide member has multiple first drainage holes. Both the second and first drainage holes are connected to the drainage channel, and the diameter of the second drainage holes is larger than that of the first drainage holes. Rainwater can enter the drainage channel sequentially through the second and first drainage holes. The second and first drainage holes perform a two-stage filtration process on the rainwater carrying waste, reducing the risk of clogging in the drainage channel and ensuring smooth drainage. In addition, the cover plate and the overlapping parts are detachably connected, and the drainage auxiliary support and the tank are connected in a coordinated manner through overlapping and abutting. When some waste accumulates in the cover plate, drainage auxiliary support or drainage tank due to long-term use of the drainage structure, workers can remove the cover plate or drainage auxiliary support in time and clean it. The overall cleaning and disassembly difficulty of the drainage structure is relatively low. Attached Figure Description

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0031] Road drainage typically utilizes the cross and longitudinal slopes of the road surface to quickly guide rainwater into roadside drainage structures. Currently, the commonly used drainage structure is a drainage ditch covered with a mesh cover. Over time, debris such as stones, litter, and leaves on the road surface can be washed into the drainage ditch by rainwater through the mesh cover. In sections with low rainfall and narrow drainage ditches, this debris can easily accumulate, causing blockages and hindering effective drainage. This allows rainwater to seep into the road base and damage the road surface.
[0032] To ensure the smooth progress of the drainage process, such as Figures 1-3As shown, this embodiment provides a drainage structure, including a tank 1, a drainage auxiliary support 2, and a cover plate 3. The tank 1 has a drainage trough 11 along its height, with the opening of the drainage trough 11 facing upwards. The drainage auxiliary support 2 includes a connecting member 21, a connecting member 22, and a guide member 23 connected in sequence and arranged at an angle. The connecting member 21 overlaps the top surface of the tank 1, the connecting member 22 abuts against the wall of the drainage trough 11, and at least a portion of the guide member 23 is arranged at an angle to the bottom of the drainage trough 11 and has multiple first drainage holes 234, all of which are connected to the drainage trough 11. The cover plate 3 is disposed above the drainage auxiliary support 2 and is detachably connected to the connecting member 21. The cover plate 3 has multiple second drainage holes 31, all of which are connected to the first drainage holes 234. The diameter of the second drainage holes 31 is larger than the diameter of the first drainage holes 234. Understandably, multiple drainage auxiliary supports 2 are spaced apart along the length of the drainage channel 11 to improve the overall filtration effect of rainwater carrying waste.
[0033] In this embodiment, the tank 1 has a drainage groove 11. The overlapping member 21 overlaps the top surface of the tank 1 and is detachably connected to the cover plate 3. The connecting member 22 abuts against the wall of the drainage groove 11. Compared with the single snap-fit method between the drainage frame and the cover plate 3 in the prior art, the connection strength and overall integrity between the tank 1, the drainage auxiliary support 2, and the cover plate 3 in the drainage structure proposed in this embodiment are improved. The overlapping member 21 can also improve the adaptability of the drainage auxiliary support 2 to tanks 1 of different sizes, and improve the versatility of the drainage auxiliary support 2. The cover plate 3 has multiple second drainage holes 31, and the guide member 23 has multiple first drainage holes 234. Both the second drainage holes 31 and the first drainage holes 234 are connected to the drainage trough 11, and the diameter of the second drainage hole 31 is larger than that of the first drainage hole 234. Rainwater can enter the drainage trough 11 after passing through the second drainage holes 31 and the first drainage holes 234 in sequence. The second drainage holes 31 and the first drainage holes 234 can perform a two-stage filtration process on the rainwater carrying waste, preventing large waste from entering the drainage trough 11 and affecting the drainage efficiency. Compared with the prior art that only has second drainage holes 31, the addition of first drainage holes 234 reduces the risk of blockage in the drainage trough 11, ensures the smooth progress of the drainage process, and avoids the damage to the road base caused by rainwater accumulation on the road surface. Furthermore, the cover plate 3 and the overlapping member 21 are detachably connected, and the drainage auxiliary support 2 and the trough 1 are connected in a coordinated manner through overlapping and abutment. When some waste accumulates in the cover plate 3, drainage auxiliary support 2, or drainage trough 11 due to long-term use of the drainage structure, workers can promptly remove the cover plate 3 or drainage auxiliary support 2 for cleaning. The overall cleaning and disassembly difficulty of the drainage structure is relatively low. Compared with the prior art of checking the blockage of drainage trough 11 in each section one by one, workers only need to clean the drainage structure in this embodiment periodically, reducing the cost of manpower and equipment.
[0034] Optionally, the guide member 23 includes a first guide section 231 and a second guide section 232 connected to each other. Both the first guide section 231 and the second guide section 232 are angled to the bottom of the drainage trough 11 and each has multiple first drainage holes 234. A connector 22 is connected to each side of the first guide section 231 and the second guide section 232 that are away from each other. The angled arrangement of the first guide section 231 and the second guide section 232 with the bottom of the drainage trough 11 improves the overall rainwater guiding effect of the guide member 23. The connector 22 abuts against the wall of the drainage trough 11. The connector 22 and the wall of the drainage trough 11 provide stable support for the guiding process of the first guide section 231 and the second guide section 232, limiting the deformation of the first guide section 231 and the second guide section 232 during the guiding process and improving the structural stability of the guide member 23.
[0035] Specifically, the guide member 23 also includes a support portion 233. The first guide portion 231 is connected to the second guide portion 232 through the support portion 233, and the support portion 233 is in contact with the bottom surface of the cover plate 3. The support portion 233 can share the load borne by the first guide portion 231 and the second guide portion 232 during the flow diversion process. Furthermore, the support portion 233 increases the contact area between the guide member 23 and the cover plate 3, reducing the displacement of the cover plate 3 relative to the tank 1 or the drainage auxiliary support 2 caused by rainwater erosion. Compared to a direct connection between the first guide portion 231 and the second guide portion 232, the support portion 233 also reduces the risk of stress concentration at the connection point. For example, the first guide portion 231 and the second guide portion 232 are symmetrically arranged relative to the support portion 233, and the ends of the first guide portion 231 and the second guide portion 232 that are furthest from each other both extend downwards along the direction close to the wall of the drainage tank 11.
[0036] For example, such as Figure 2 As shown, one of the connecting piece 21 and the cover plate 3 has a connecting hole 32, and the other has a connecting protrusion 211 that engages with the connecting hole 32. With the help of the engaging connection of the connecting hole 32 and the connecting protrusion 211, the cover plate 3 and the connecting piece 21 can be quickly assembled, and the assembly and disassembly process is simple and easy to implement.
[0037] Optionally, such as Figure 1 and Figure 3 As shown, the drainage auxiliary support 2 also includes a support member 24. The support member 24 is located at one end of the guide member 23 near the wall of the drainage trough 11 and parallel to the bottom of the drainage trough 11. One end of the support member 24 is connected to the guide member 23, and the other end is connected to the connector 22. The guide member 23 is connected to the connector 22 through the support member 24. The support member 24 can support waste in the rainwater that passes through the second drainage hole 31 but cannot pass through the first drainage hole 234, thus preventing waste from clogging the first drainage hole 234 and affecting the guiding effect of the guide member 23. The support member 24 not only ensures the normal filtration effect of the first drainage hole 234, but also facilitates the subsequent waste cleaning operation by workers.
[0038] Optionally, the drainage structure also includes a handle, which is detachably mounted on the top surface of the cover plate 3. Before installation, the handle is mounted on the cover plate 3 to provide a point of leverage for manual installation or tool-assisted installation, thus improving the installation operation of the cover plate 3. After installation, the handle is removed to avoid the risk of bumping or knocking when personnel or vehicles pass by.
[0039] For example, the top of the trough 1 has an installation groove along its length. The overlapping member 21 overlaps the bottom of the installation groove, and the cover plate 3 abuts against the wall of the installation groove, with the top surface of the cover plate 3 flush with the opening of the installation groove. The installation groove improves the connection stability of the cover plate 3, the overlapping member 21, and the trough 1, reducing the risk of swaying of the cover plate 3 or the drainage auxiliary support 2 relative to the trough 1 during heavy rain, thus improving the overall integrity and reliability of the drainage structure. The flush alignment of the top surface of the cover plate 3 with the opening of the installation groove enhances the structural stability of the drainage structure, preventing potential collisions when vehicles or personnel pass by.
[0040] Specifically, the drainage structure includes a seal, which is sandwiched between the overlap 21 and the bottom of the mounting groove. The seal enhances the sealing effect at the connection between the overlap 21 and the bottom of the mounting groove, and also improves the connection strength between the overlap 21 and the bottom of the mounting groove. The seal can be a gasket or a sealing ring, etc.
[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
