Description

Technical Field

[0001] This utility model relates to the field of drainage technology, and in particular to a drainage ditch structure. Background Technology

[0002] In drainage systems of construction projects such as building engineering and municipal engineering, drainage ditches play a vital role. Typically located along roadsides, they collect and drain surface water from road surfaces, shoulders, and slopes, maintaining roadbed stability, preventing soil erosion, and ensuring environmental cleanliness and hygiene. However, existing drainage ditches and related facilities have revealed numerous problems in practical applications, severely impacting their functionality and the quality of the surrounding environment.

[0003] Currently, to prevent pedestrians from slipping and falling into drainage ditches, a cover is usually installed at the top of the ditch, with drainage holes on the cover for drainage. However, garbage, leaves, or other debris on the road can be washed into the drainage ditch by surface water through the drainage holes. Under long-term soaking conditions, this produces an unpleasant odor. Since the drainage holes on the cover are open to the outside air, the odor produced in the drainage ditch will spread into the air, which not only seriously affects the surrounding air quality but may also cause environmental hygiene and safety problems. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage ditch structure to solve the problem that odors in drainage ditches in the prior art can easily be emitted into the outside air, affecting air quality and easily causing environmental hygiene and safety issues.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A drainage ditch structure, comprising:

[0007] A drainage channel and a cover plate, wherein the cover plate is installed over the drainage channel; the cover plate has an installation groove for connecting the drainage channel to the external road surface; a blocking structure is installed in the installation groove.

[0008] The blocking structure includes a baffle installed in a mounting groove. The baffle is configured to rotate within the mounting groove to open the mounting groove, connecting the drainage ditch to the external road surface for drainage; or / and close the mounting groove, preventing the drainage ditch from connecting to the external road surface to prevent the spread of odors from the drainage ditch.

[0009] Based on the aforementioned technical means, by setting an installation groove on the cover plate and cooperating with a blocking structure, the functions of flexible and effective drainage and prevention of odor from the drainage trough from spreading to the outside air are achieved. Specifically, when drainage is needed, surface water on the road surface flows into the installation groove and presses against the baffle. Under the weight of the water, the baffle rotates and opens the installation groove, connecting the drainage trough with the external road surface, thus ensuring the smooth flow of surface water into the drainage trough. When drainage ends, the baffle rotates and closes the installation groove, preventing the drainage trough from being connected to the external road surface. This effectively prevents the odor generated by long-term soaking of debris in the drainage trough from spreading to the outside air, improving the surrounding air quality, and avoiding environmental hygiene and safety problems that may be caused by odor diffusion. The structure is simple and easy to operate and maintain.

[0010] Furthermore, the blocking structure also includes a panel, which is installed in the mounting groove and located above the baffle. At least one drainage groove is formed on the panel, and each drainage groove is used to connect the mounting groove with the external road surface.

[0011] Based on the aforementioned technical means, by installing the panel above the baffle, not only can pedestrians be prevented from stepping into the mounting groove, but the baffle can also be protected and its service life extended. Furthermore, the drainage grooves formed by the panel not only ensure smooth drainage of the road surface, but also, due to its groove structure, can more effectively intercept larger debris compared to ordinary drainage holes, reducing the possibility of debris entering the drainage groove and causing blockage. The compact structure not only improves the drainage ditch's ability to prevent odors and blockages, but also enhances its overall stability and durability, better meeting actual usage needs.

[0012] Furthermore, the blocking structure also includes an annular mounting beam, which is fixed to the inner wall of the mounting groove. The panel is supported on the annular mounting beam, and the baffle is located below the annular mounting beam.

[0013] Based on the aforementioned technical means, the ring-shaped mounting beam provides a stable support platform for the panel, ensuring not only the flatness and stability of the panel but also its load-bearing capacity. It prevents pedestrians from slipping and enhances the protection of the baffle. When it is necessary to clean debris in the drainage channel or install and maintain the baffle, the panel can be quickly disassembled and assembled, improving work efficiency and ease of disassembly and assembly. This enhances the overall reliability, durability, drainage and odor prevention performance of the drainage ditch structure and reduces subsequent maintenance costs.

[0014] Furthermore, a rotating shaft is fixed on the centerline of the baffle, and the end of the rotating shaft away from the baffle is rotatably mounted on the inner wall of the mounting groove. The rotating shaft is configured to rotate circumferentially, thereby driving the baffle to rotate within the mounting groove to open and / or close the mounting groove.

[0015] Based on the aforementioned technical means, the baffle is rotatably installed in the mounting slot via a pivot on the center line, achieving flexible and stable rotation of the baffle. This allows for easy and reliable opening and closing of the mounting slot. Furthermore, the pivot is located on the center line of the baffle, meaning that during drainage, the baffle can open the mounting slot by rotating in both forward and reverse directions along the pivot, making drainage more convenient and smooth. The design is simple, easy to install, stable, and reliable in operation. It reduces friction and the failure rate of the baffle rotation, extends the baffle's service life, facilitates maintenance and replacement, and enhances the convenience and practicality of the drainage ditch.

[0016] Furthermore, it also includes a reset drive structure, which is connected to one end of the rotating shaft. The reset drive structure is configured to drive the rotating shaft to rotate the baffle to close the mounting slot.

[0017] Based on the above technical means, the reset drive structure provides reliable power support for the automatic reset of the baffle to the initial state after drainage to close the installation slot. Specifically, in practical applications, after drainage, the reset drive structure can drive the rotating shaft to rotate the baffle to the initial state, thereby quickly and accurately closing the installation slot without additional manual operation, improving the convenience and efficiency of use, and avoiding the failure of the baffle to close in time due to human negligence or external factors. It has high reliability and good stability.

[0018] Furthermore, the reset drive structure includes a mounting plate, a toggle member, and an elastic member. The mounting plate is mounted on the inner wall of the mounting groove, the toggle member is mounted on one end of the rotating shaft, and one end of the elastic member is fixed to the mounting plate, while the other end is connected to the toggle member. The toggle member is configured to swing to deform the elastic member when the rotating shaft rotates to open the mounting groove with the baffle; when the elastic member is reset, the toggle member can swing to drive the rotating shaft to rotate, thereby closing the mounting groove with the baffle.

[0019] Based on the above technical means, in practical applications, when the baffle opens the installation slot to drain water, the actuating component rotates with the shaft, causing the elastic component to deform and thus store energy; when the drainage ends, the elastic component resets and releases energy, thereby driving the actuating component to swing and drive the shaft to rotate, thus enabling the baffle to close the installation slot accurately and quickly. The structure is compact, and it uses the elastic potential energy of the elastic component to achieve automated operation without the need for additional energy drive, reducing the cost of use. It also operates stably and responds quickly, improving the odor prevention performance and ease of use of the drainage ditch structure.

[0020] Furthermore, the reset drive structure also includes a guide rod, which is slidably mounted on the mounting plate. One end of the guide rod is rotatably mounted with a disk, and the other end is connected to the other end of the elastic element. The disk abuts against the actuating element. The guide rod is configured to move along its length when the actuating element swings, so as to compress or stretch the elastic element.

[0021] Based on the aforementioned technical means, the guide rod provides precise and stable guidance for the deformation process of the elastic element. Specifically, in practical applications, when the actuating component swings, it squeezes the disc. The rotating disc reduces the friction between itself and the actuating component, thereby pushing the guide rod to move smoothly along its length, compressing or stretching the elastic element. This avoids instability such as displacement or twisting of the elastic element during the stress process, ensuring the uniformity and reliability of the elastic element's deformation. This, in turn, guarantees a continuous and stable output of power, allowing the baffle to smoothly complete the opening and closing actions, improving the stability and durability of the entire drainage ditch structure, reducing potential failures, extending service life, and lowering maintenance costs.

[0022] Furthermore, the elastic element is a hook spring, the length of which is set along the length direction of the guide rod. One end of the hook spring is fixed to the mounting plate by a positioning post, and the other end is connected to the other end of the guide rod.

[0023] Based on the above technical means, using a hook spring as an elastic element has good elasticity and fatigue resistance. The hook spring is arranged along the length of the guide rod, which can more directly and effectively transmit the elastic force to the guide rod, ensuring that the hook spring can be accurately and evenly compressed or stretched when the actuating part swings, generating a stable and reliable restoring force.

[0024] Furthermore, it also includes a limiting collar, which is fixed on the mounting plate, and one end of the rotating shaft is rotatably sleeved inside the limiting collar.

[0025] According to the above technical means, one end of the rotating shaft is rotatably connected to the mounting plate through a limiting collar. The limiting collar provides precise and stable rotational support and limit for the rotating shaft, which can constrain the rotation trajectory of the rotating shaft and prevent it from deviating or shaking during rotation. This ensures that the rotating shaft always rotates smoothly along the predetermined axis, thereby ensuring that the baffle connected to the rotating shaft can accurately open and close the mounting slot, improving the accuracy and reliability of the baffle movement.

[0026] Furthermore, the number of the mounting slots is two or more, each mounting slot is evenly distributed along the length of the drainage channel, and each mounting slot is equipped with a blocking structure.

[0027] Based on the above technical means, by setting two or more installation slots that are evenly distributed along the length of the drainage channel and each equipped with a blocking structure, the drainage channel can be protected in a more comprehensive and detailed manner. This not only ensures the smooth drainage of the filter cotton, but also blocks the emission of odors that may be generated in different locations, greatly enhancing the odor prevention effect. In addition, the evenly distributed drainage channel is subjected to uniform stress in each part, reducing the risk of structural damage caused by excessive local pressure.

[0028] The beneficial effects achieved by this utility model are:

[0029] This utility model achieves flexible and effective drainage and prevents odors from spreading from the drainage ditch to the outside air by setting an installation groove on the cover plate and using a blocking structure. Specifically, when drainage is needed, surface water on the road flows into the installation groove and presses against the baffle. Under the weight of the water, the baffle rotates and opens the installation groove, connecting the drainage ditch to the outside road surface, thus ensuring smooth drainage. When drainage ends, the baffle rotates and closes the installation groove, preventing the drainage ditch from being connected to the outside road surface. This effectively prevents odors caused by long-term soaking of debris in the drainage ditch from spreading to the outside air, improving the surrounding air quality and avoiding environmental hygiene and safety problems that may be caused by odor diffusion. The structure is simple and easy to operate and maintain. Attached Figure Description

[0042] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0043] This embodiment relates to a drainage ditch structure, such as Figure 1 and Figure 2 As shown, it includes: a drainage channel 1 and a cover plate 2, with the cover plate 2 covering the drainage channel 1; an installation groove 21 is formed on the cover plate 2, which is used to connect the drainage channel 1 with the external road surface; a blocking structure is installed in the installation groove 21; the blocking structure includes a baffle 31, which is installed in the installation groove 21 and is configured to rotate within the installation groove 21 to open the installation groove 21, so that the drainage channel 1 is connected to the external road surface for drainage; or / and close the installation groove 21, so that the drainage channel 1 is not connected to the external road surface to prevent the spread of odor from the drainage channel 1.

[0044] In this embodiment, by setting an installation groove 21 on the cover plate 2 and cooperating with a blocking structure, flexible and effective drainage and prevention of odor from the drainage ditch 1 from spreading to the outside air are achieved. Specifically, in practical application, the baffle 31 is in its initial state when the installation groove 21 is closed. When drainage is needed, surface water on the road surface flows into the installation groove 21 and presses against the baffle 31. Under the weight of the water, the baffle 31 rotates and opens the installation groove 21, connecting the drainage ditch 1 with the outside road surface, thus ensuring the smooth drainage of the road surface. When drainage ends, the baffle 31 rotates back to its initial state to close the installation groove 21, preventing the drainage ditch 1 from being connected to the outside road surface. This effectively prevents the odor generated by long-term soaking of debris in the drainage ditch 1 from spreading to the outside air, improving the surrounding air quality, and avoiding environmental hygiene and safety problems that may be caused by odor diffusion. The structure is simple, easy to operate and maintain. Those skilled in the art will understand that the drainage ditch structure in this utility model can be applied to projects that require drainage, such as roads, slopes, and shoulders.

[0045] like Figure 2 As shown, in this embodiment, the blocking structure also includes a panel 32, which is installed in the mounting groove 21 and located above the baffle 31. At least one drainage groove 321 is formed on the panel 32, and each drainage groove 321 is used to connect the mounting groove 21 with the external road surface.

[0046] In this embodiment, the panel 32 is installed above the baffle 31, which not only prevents pedestrians from falling into the mounting groove 21, but also protects the baffle 31 and extends its service life. Furthermore, the drainage grooves formed by the panel 32 not only ensure the smooth drainage of the road surface, but also, due to their groove structure, can more effectively intercept larger debris compared to ordinary drainage holes, reducing the possibility of debris entering the drainage channel 1 and causing blockage. The compact structure not only improves the drainage ditch's ability to prevent odors and blockages, but also enhances the overall stability and durability, better meeting the actual use needs.

[0047] like Figure 3 As shown, in this embodiment, the blocking structure also includes an annular mounting beam 33, which is fixed on the inner wall of the mounting groove 21. The panel 32 is supported on the annular mounting beam 33, and the baffle 31 is located below the annular mounting beam 33.

[0048] In this embodiment, the annular mounting beam 33 provides a stable support platform for the panel 32, which not only ensures the flatness and stability of the panel 32, but also ensures the load-bearing capacity of the panel 32. It prevents pedestrians from stepping into the hole and improves the protection of the baffle 31. When it is necessary to clean the debris in the drainage channel 1 or install and maintain the baffle 31, the panel 32 can be quickly disassembled and assembled, which improves work efficiency and ease of disassembly and assembly, enhances the overall reliability, durability and drainage and odor prevention performance of the drainage ditch structure, and reduces the later maintenance cost.

[0049] like Figure 3 and Figure 4 As shown, in this embodiment, a rotating shaft 311 is fixed on the center line of the baffle 31. The end of the rotating shaft 311 away from the baffle 31 is rotatably mounted on the inner wall of the mounting groove 21. The rotating shaft 311 is configured to rotate circumferentially, thereby driving the baffle 31 to rotate within the mounting groove 21 to open and / or close the mounting groove 21.

[0050] In this embodiment, the baffle 31 is rotatably installed in the mounting groove 21 via a rotating shaft 311 on the center line. This enables the baffle 31 to rotate flexibly and stably, allowing for easy and reliable opening and closing of the mounting groove 21. The rotating shaft 311 is located on the center line of the baffle 31, ensuring that during drainage, the baffle 31 can open the mounting groove 21 by rotating in both forward and reverse directions along the rotating shaft 311. This makes drainage more convenient and smooth. The structure is simple, easy to install, stable, and reliable in operation. It reduces the friction and failure rate of the baffle 31 during rotation, extends the service life of the baffle 31, facilitates maintenance and replacement of the baffle 31, and improves the convenience and practicality of the drainage ditch.

[0051] like Figure 2 , Figure 3 and Figure 4As shown, this embodiment also includes a reset drive structure, which is connected to one end of the rotating shaft 311. The reset drive structure is configured to drive the rotating shaft 311 to rotate the baffle 31 to close the mounting slot 21.

[0052] This embodiment provides reliable power support for the automatic reset of the baffle 31 to its initial state after drainage to close the mounting slot 21 through the reset drive structure. Specifically, in practical applications, after drainage, the reset drive structure can drive the rotating shaft 311 to rotate the baffle 31 to reset to its initial state, thereby quickly and accurately closing the mounting slot 21 without the need for additional manual operation, improving the convenience and efficiency of use, and avoiding the failure of the baffle 31 to close in time due to human negligence or external factors. It has high reliability and good stability.

[0053] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the reset drive structure includes a mounting plate 41, a toggle member 42, and an elastic member 43. The mounting plate 41 is mounted on the inner wall of the mounting groove 21. The toggle member 42 is mounted on one end of the rotating shaft 311. One end of the elastic member 43 is fixed on the mounting plate 41, and the other end is connected to the toggle member 42. The toggle member 42 is configured to swing to deform the elastic member 43 when the rotating shaft 311 rotates to open the mounting groove 21 with the baffle 31. When the elastic member 43 is reset, the toggle member 42 can swing to drive the rotating shaft 311 to rotate, so that the baffle 31 closes the mounting groove 21.

[0054] In this embodiment, during practical application, when the baffle 31 opens the mounting slot 21 to drain water, the actuating element 42 rotates with the rotating shaft 311, causing the elastic element 43 to deform and store energy. When the drainage ends, the elastic element 43 resets and releases energy, thereby driving the actuating element 42 to swing and drive the rotating shaft 311 to rotate, thus enabling the baffle 31 to accurately and quickly close the mounting slot 21. The structure is compact, and the elastic potential energy of the elastic element 43 is used to achieve automated operation without the need for additional energy drive, reducing the cost of use. It also operates stably and responds quickly, improving the odor prevention performance and ease of use of the drainage ditch structure.

[0055] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the reset drive structure also includes a guide rod 44, which is slidably mounted on the mounting plate 41. One end of the guide rod 44 is rotatably mounted with a disk 45, and the other end is connected to the other end of the elastic member 43. The disk 45 abuts against the actuating member 42. The guide rod 44 is configured to move along its length direction when the actuating member 42 swings, so as to compress or stretch the elastic member 43.

[0056] This embodiment provides precise and stable guidance for the deformation process of the elastic element 43 through the guide rod 44. Specifically, in practical applications, when the actuating element 42 swings, it squeezes the disc 45. The rotating disc 45 reduces the friction between itself and the actuating element 42, thereby pushing the guide rod 44 to move smoothly along its length, compressing or stretching the elastic element 43. This avoids instability such as displacement or twisting of the elastic element 43 during the force process, ensuring the uniformity and reliability of the deformation of the elastic element 43, and thus guaranteeing a continuous and stable output of power. This allows the baffle 31 to smoothly complete the opening and closing action, improving the overall efficiency of the entire process. The stability and durability of the drainage ditch structure reduce potential failures, extend service life, and lower maintenance costs. Among them, the actuating element 42 is a V-shaped structure, with the tip of the V-shaped structure fixed to one end of the rotating shaft 311. The open end of the V-shaped structure faces the disc 45, and the outer circumferential surface of the disc 45 abuts against the inner wall of the V-shaped structure. When the rotating shaft 311 drives the V-shaped structure to swing, the disc 45 always maintains contact with one inner wall of the V-shaped structure and slides relative to it within the V-shaped structure as it swings. This converts the swing of the V-shaped structure into the linear movement of the guide rod 44, thereby achieving the compression or stretching of the elastic element 43.

[0057] Furthermore, as a preferred embodiment of this invention, the elastic element 43 is a hook spring, the length of which is set along the length direction of the guide rod 44. One end of the hook spring is fixed to the mounting plate 41 by the positioning post 431, and the other end is connected to the other end of the guide rod 44. In this embodiment, the hook spring is used as the elastic element 43, which has good elasticity and fatigue resistance. The hook spring is arranged along the length direction of the guide rod 44, which can more directly and effectively transmit the elastic force to the guide rod 44, ensuring that when the actuating element 42 swings, the hook spring can be accurately and evenly compressed or stretched to generate a stable and reliable restoring force.

[0058] like Figure 4 As shown, in this embodiment, a limiting collar 46 is also included. The limiting collar 46 is fixed on the mounting plate 41, and one end of the rotating shaft 311 is rotatably sleeved in the limiting collar 46.

[0059] In this embodiment, one end of the rotating shaft 311 is rotatably connected to the mounting plate 41 via a limiting collar 46. The limiting collar 46 provides precise and stable rotational support and limiting for the rotating shaft 311, which can constrain the rotation trajectory of the rotating shaft 311 and prevent it from deviating or shaking during rotation. This ensures that the rotating shaft 311 always rotates smoothly along the predetermined axis, thereby ensuring that the baffle 31 connected to the rotating shaft 311 can accurately open and close the mounting groove 21, thus improving the accuracy and reliability of the movement of the baffle 31.

[0060] Furthermore, as a preferred embodiment of this example, the number of mounting slots 21 is two or more, each mounting slot 21 is evenly distributed along the length of the drainage channel 1, and each mounting slot 21 is equipped with a blocking structure. By setting two or more mounting slots 21 that are evenly distributed along the length of the drainage channel 1 and are equipped with blocking structures, the drainage channel 1 can be protected in a more comprehensive and detailed manner. This not only ensures the smooth drainage of the filter cotton, but also blocks the emission of odors that may be generated at different locations, greatly enhancing the odor-proof effect. Moreover, the evenly distributed drainage channel 21 is subjected to uniform stress in each part, reducing the risk of structural damage caused by excessive local pressure.

[0061] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
