Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, specifically to a municipal road drainage structure. Background Technology

[0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, and equipment set up within the planned construction area of ​​urban areas and towns to provide paid or free public goods and services to residents based on the government's responsibility and obligation. The construction of various public infrastructure supporting urban life falls under the scope of municipal engineering. Examples include common urban roads, bridges, subways, and various pipelines closely related to daily life: rainwater, sewage, water supply, greywater, electricity (outside the red line), telecommunications, heating, gas, etc. The construction of squares and urban green spaces also falls under the scope of municipal engineering. The drainage structure commonly seen along roads is a concrete structure poured into water... Square drainage covers on muddy roads utilize water on their surface for drainage. Because pedestrians frequently walk on and step on these covers, the concrete they are cast into provides strong support. However, this design also has drawbacks. To ensure sufficient drainage, the drainage channel is quite wide. When the channel is too wide, items like cell phones, keys, and earphones can easily fall directly into the channel. In such cases, the concrete base cast into the surface of the drainage cover needs to be broken to remove it, and then the cover needs to be resealed with concrete. This process is very troublesome. Furthermore, if the channel becomes clogged, manual unblocking is required; otherwise, it will severely affect the drainage capacity.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN218479285U discloses a municipal road drainage structure, comprising a drainage channel, an installation frame, and a fixing plate. The installation frame is located inside the drainage channel, and the fixing plate is fixedly installed on the front and rear sides of the drainage channel. A drainage cover is hinged to the right side of the upper surface of the installation frame, and a fastening stud is fixedly installed on the left side of the upper surface of the installation frame. A fastening nut is threaded onto the outer surface of the fastening stud.

[0004] Although the existing technical solution mentioned above allows users to open the drain cover and retrieve dropped items by loosening the fastening nut and separating it from the drain cover, it still requires personnel to rotate the corresponding fastening bolt and fastening nut one circle at a time when unlocking the drain cover. The disassembly and assembly process is cumbersome and time-consuming, increasing the workload of personnel and the efficiency of retrieving items. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figures 1-3This utility model provides a technical solution:

[0023] A municipal road drainage structure includes a drainage channel 1, an installation frame 2 installed on the inner side of the drainage channel 1, a drainage groove at the top of the installation frame 2, a drainage cover 3 rotatably connected to the inner side of the drainage groove, a sealing gasket 4 embedded in one side of the drainage cover 3, an operating groove at the top of the installation frame 2 on one side of the drainage groove, and the drainage cover 3 being snapped into the installation frame 2 by an installation mechanism. The installation mechanism includes a pushing component and a spring-loaded positioning component. The pushing component is used to initially align the drainage cover 3 and the installation frame 2, and the spring-loaded positioning component is used to lock or unlock the positional relationship between the drainage cover 3 and the installation frame 2. In use, the device can initially align the drainage cover 3 and the installation frame 2 through the pushing component, and lock or unlock the positional relationship between the drainage cover 3 and the installation frame 2 through the spring-loaded positioning component. The structure is simple and easy to operate, allowing personnel to quickly lock and unlock the drainage cover 3, reducing the workload of personnel and saving disassembly and assembly time.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the pushing assembly includes a synchronization groove 5 formed at the bottom of the inner wall of the operating groove. A synchronization block is slidably connected to the inner side of the synchronization groove 5. The cross-section of the synchronization block and the synchronization groove 5 is T-shaped. A fixing plate 6 is installed at the other end of the synchronization block. A docking block 7 is installed on one side of the fixing plate 6. A rubber pad 9 is installed on one side of the fixing plate 6. A docking hole is opened inside the rubber pad 9. The inner wall of the docking hole fits with the outer wall of the docking block 7. An installation seat 10 is installed on the side of the sealing gasket 4 away from the drain cover 3. A docking groove is opened on one side of the installation seat 10 to slidably connect with the docking block 7. The length and width dimensions of the cross-section of the sealing gasket 4 are both larger than the length and width dimensions of the cross-section of the operating groove. First, the drain cover 3 is flipped inside the drain groove, allowing the installation seat 10 to enter the inner side of the operating groove. The sealing gasket 4 fits against the inner wall of the drain groove. Then, one side of the fixing plate 6 is pressed down to cooperate with the synchronization groove 5 and the synchronization block to push the rubber pad 9 and the docking block 7 towards the installation seat 10. The docking block 7 will fit with the docking groove.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the spring-loaded positioning assembly includes a mounting groove located inside the mounting base 10 on one side of the docking groove. A first movable rod 8 is rotatably connected to one end of the mounting groove. A spring-loaded block 11 is sleeved on the outer side of the first movable rod 8. The opposing surfaces of the spring-loaded block 11 and the docking block 7 are both provided with inclined surfaces. The two sets of inclined surfaces fit together. Then, the docking block 7 will fit into the docking groove. Subsequently, the fixing plate 6 is pressed to compress the rubber pad 9. The docking block 7 gradually moves towards the inside of the mounting groove. After contacting the spring-loaded block 11, it is forced to fit together and compress. This forces the spring-loaded block 11 and the first movable rod 8 to rotate around the center of the first movable rod 8, thus stretching the fixing spring 13.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a retraction groove is provided inside the spring-loaded block 11 at its inclined surface. A retraction rod 14 is rotatably connected to the inside of the retraction groove. A retraction plate 15 is installed on the outside of the retraction rod 14. A slope 16 that fits against the inclined surface is provided on one side of the retraction plate 15. A torsion spring 17 is installed between one end of the retraction rod 14 and the inner wall of the retraction groove. Further, as the downward movement progresses, the inclined surface on the docking block 7 contacts the slope 16 on the retraction plate 15, forcing the retraction rod 14 to rotate. The torsion spring 17 and the retraction plate 15 then retract to the inside of the retraction groove. After the abutment groove on the docking block 7 is pushed to the retraction groove, the torsion spring 17 will drive the retraction plate 15 to spring into the abutment groove. At this time, the compression is no longer applied, and the rubber pad 9 will spring back a short distance. The abutment groove moves upward and abuts against one side of the retraction plate 15, completing the quick locking of the drainage cover 3.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a fixing groove is provided inside the spring-loaded block 11 on one side of the inclined surface. A fixing spring 13 is installed between the fixing groove and the inner wall of the mounting groove. The other end of the fixing spring 13 is fixedly connected to the inner wall of the mounting groove. A knob 12 is installed at the end of the first movable rod 8 that extends to the outside of the mounting base 10. The outer wall of the knob 12 should have anti-slip texture. A sliding connection limiting groove is provided on the inner wall of the mounting groove. A limiting plate 18 is installed at the end of the spring-loaded block 11 away from the inclined surface. The limiting plate 18 is slidably connected to the limiting groove. The mating block 7 The outer wall has an abutment groove on its slope. Furthermore, when it is necessary to open the drain cover 3, the knob 12 can be squeezed to drive the first movable rod 8 to rotate. In conjunction with the limiting plate 18 and the limiting groove, the spring block 11 can be driven to rotate actively, allowing the retractable plate 15 to disengage from the inside of the abutment groove. After disengagement, the rubber pad 9 will fully rebound, causing the abutment groove to move upward away from the retractable plate 15 and the retractable groove, thus releasing the position fixation of the drain cover 3. Then the drain cover 3 can be lifted to pick up the dropped items.

[0028] The implementation principle of a municipal road drainage structure according to an embodiment of this application is as follows: The drainage cover 3 is flipped inside the drainage trough, allowing the mounting base 10 to enter the operating trough. The sealing gasket 4 adheres to the inner wall of the drainage trough. Then, one side of the fixing plate 6 is pressed down, and in conjunction with the synchronous groove 5 and synchronous block, the rubber gasket 9 and the connecting block 7 are pushed towards the mounting base 10. The connecting block 7 will then align with the connecting groove. Subsequently, the fixing plate 6 is further squeezed, causing the rubber gasket 9 to retract. The connecting block 7 gradually moves towards the inner side of the mounting groove, and upon contact with the spring-loaded block 11, it is forced to engage. The two sets of inclined surfaces are pressed together, forcing the spring-loaded block 11 and the first movable rod 8 to rotate around the center of the first movable rod 8, stretching the fixing spring 13. As the downward movement increases, the inclined surface on the connecting block 7 contacts the slope 16 on the retraction plate 15, forcing the retraction rod 14 to rotate. The torsion spring 17 and the retraction plate 15 retract into the retraction groove. After the abutment groove on the docking block 7 is pushed into the retraction groove, the torsion spring 17 will cause the retraction plate 15 to spring into the abutment groove. At this time, the pressure will stop, and the rubber pad 9 will spring back a short distance. The abutment groove moves up and abuts against one side of the retraction plate 15, completing the quick locking of the drain cover 3. When the drain cover 3 needs to be opened, the knob 12 can be pinched to drive the first moving rod 8 to rotate. With the help of the limiting plate 18 and the limiting groove, the spring block 11 can be driven to rotate actively, allowing the retraction plate 15 to disengage from the abutment groove. After disengagement, the rubber pad 9 will fully spring back, causing the abutment groove to move up away from the retraction plate 15 and the retraction groove, releasing the position fixation of the drain cover 3. Then the drain cover 3 can be lifted to pick up the dropped items.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
