Description

Technical Field

[0001] This application relates to the technical field of drainage structures, and in particular to a municipal road drainage structure. Background Technology

[0002] Currently, municipal road drainage structures are an important component of urban infrastructure, and their design and construction quality directly affect the city's flood control and drainage capabilities, traffic safety, and environmental protection.

[0003] Drainage ditches are an important component of municipal road drainage systems, primarily used to collect and guide surface water, prevent water accumulation from damaging road structures, and ensure traffic safety. Drainage ditches are typically located on both sides of roads. To ensure the safety of pedestrians and vehicles, drainage ditches are usually topped with covers. These covers prevent pedestrians or objects from accidentally falling into the ditches and reduce the risk of blockages caused by debris entering the ditches. To facilitate cleaning by construction workers, the covers are often simply laid on top of the ditches. This installation method makes the covers prone to shifting under external forces. As the shift increases, the probability of the covers falling into the ditches also increases, thus posing a certain safety hazard. Utility Model Content

Detailed Implementation

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a municipal road drainage structure.

[0028] Reference Figure 1 , Figure 2 The municipal road drainage structure includes a drainage ditch 1 and a cover plate 2 laid at the top opening of the drainage ditch 1. Multiple spaced-apart holes 20 are provided on the cover plate 2, allowing rainwater from the road surface to drain into the drainage ditch 1. Four vertically oriented insertion rods 21 are fixedly installed at the bottom of the cover plate 2, arranged circumferentially around the holes 20. Four corresponding insertion slots 11 are provided on the inner top wall of the drainage ditch 1, with the insertion rods 21 inserted into their respective slots from top to bottom. The interlocking of the insertion rods 21 and the insertion slots 11 restricts the horizontal displacement of the cover plate 2, thereby improving its stability and strengthening the connection between the cover plate 2 and the drainage ditch 1.

[0029] like Figure 2 , Figure 3 as well as Figure 4As shown, two mounting seats 3 are fixedly installed at the bottom of the trench cover 2, and the mounting seats 3 are symmetrically arranged on the left and right sides of the trench cover 2. A pin 30 is slidably installed in the mounting seat 3 along the horizontal direction. One end of the pin 30 is limited inside the mounting seat 3, and the other end extends from inside the mounting seat 3 to the outside of the mounting seat 3. The inner wall of the drainage ditch 1 is provided with pin holes 10 for the ends of the opposing pins 30 to be inserted horizontally into the drainage ditch 1.

[0030] like Figure 2 , Figure 4 as well as Figure 5 As shown, a locking spring 5 is sleeved on the outside of the pin 30 inside the mounting base 3. The locking spring 5 extends and retracts along the sliding direction of the pin 30. One end of the locking spring 5 abuts against the pin 30, and the other end abuts against the inner sidewall of the mounting base 3. The locking spring 5 is used to push the pin 30 to be inserted tightly into its respective corresponding pin hole 10. Through the mutual insertion and cooperation of the pin 30 and the pin hole 10, the trench cover 2 can be locked in the drainage ditch 1, preventing the trench cover 2 from detaching from the drainage ditch 1, and further improving the connection reliability between the trench cover 2 and the drainage ditch 1.

[0031] like Figure 5 , Figure 6 As shown, a lifting member 4 is rotatably mounted on the pin rod 30. A sliding groove 300 is formed on the outer wall of the mounting base 3, allowing the lifting member 4 to slide along the length of the pin rod 30. The length of the sliding groove 300 extends along the sliding direction of the pin rod 30. The lifting member 4 extends from the upper trench cover hole 20 to the outside of the trench cover plate 2. A clearance groove 200 is provided on the trench cover plate 2, located on the rotation path of the top of the lifting member 4. The lifting member 4, extending to the outside of the trench cover plate 2, can rotate around its own rotation axis into the clearance groove 200. When the pin rod 30 is tightly inserted into the pin hole 10, by rotating the top of the lifting member 4 into the clearance groove 200, the top of the lifting member 4 can be hidden, thereby reducing the inconvenience caused to pedestrians and protecting the lifting member 4.

[0032] When it is necessary to release the lock on the trench cover 2, the lifting member 4 is rotated out of the relief groove 200, and then the pin rod 30 is pulled away from the pin hole 10 by the lifting member 4 until the end of the pin rod 30 is moved out of its respective pin hole 10. At this time, the trench cover 2 can be easily removed from the drainage ditch 1. The operation is convenient and quick. The lifting members 4 on both sides can also provide the construction personnel with a point of leverage, making it easy to remove the trench cover 2 smoothly.

[0033] like Figure 2 , Figure 3As shown, multiple circumferentially arranged hooks 6 are fixedly installed at the bottom of the trench cover 2. An intercepting frame 7, directly opposite the trench cover hole 20, is suspended from the bottom of the trench cover 2 via each hook 6. A drainage channel 70 runs through the outer wall of the intercepting frame 7, and the width of the drainage channel 70 is smaller than the width of the trench cover hole 20. The intercepting frame 7 is used to intercept solid waste that flows into the drainage ditch 1 from the trench cover hole 20 along with rainwater, while rainwater can smoothly drain into the drainage ditch 1 through the drainage channel 70. The length of the hooks 6 can be appropriately extended according to the height of the pin 30 to ensure that the intercepting frame 7 can be easily removed from the bottom of the trench cover 2.

[0034] like Figure 3 , Figure 4 as well as Figure 5 As shown, a vertically arranged support rod 9 is threaded onto the trench cover 2. A support plate 90 is rotatably mounted at the bottom of the support rod 9, abutting against the inner bottom wall of the intercepting frame 7. The support plate 90 and the support rod 9 are coaxially arranged. A countersunk hole is provided on the upper surface of the trench cover 2. An operating handle 91 is rotatably mounted on the top of the support rod 9, located within the countersunk hole. The rotation axis of the operating handle 91 is horizontal. By rotating the operating handle 91 to a horizontal position, it is concealed within the countersunk hole, thus reducing the inconvenience to pedestrians. When it is necessary to rotate the support rod 9, first rotate the operating handle 91 to a vertical position, and then the support rod 9 can be rotated via the operating handle 91.

[0035] The interception frame 7 is pressed down by the support rod 9. At this time, the interception frame 7 will be pressed and fixed on the hook 6, ensuring the stability and reliability of the interception frame 7 and preventing the interception frame 7 from coming off the hook 6.

[0036] like Figure 2 , Figure 3 As shown, a garbage collection seat 8 is detachably installed at the bottom of the interception frame 7, which is set inside the drainage ditch 1. The outer wall of the garbage collection seat 8 is in contact with the inner wall of the drainage ditch 1. By having one side opening of the garbage collection seat 8 facing the water flow direction of the drainage ditch 1, and an interception net 800 for intercepting solid garbage in the water flow within the garbage collection seat 8 on the other side, the garbage collection seat 8 effectively prevents upstream garbage from flowing downstream and ensures the effectiveness of garbage interception.

[0037] like Figure 2 , Figure 3As shown, an adjusting member 80 extending towards the upper intercepting frame 7 is fixedly installed on the outer wall of the garbage collection seat 8. The adjusting members 80 are symmetrically arranged on the front and rear sides of the garbage collection seat 8. There are two adjusting members 80 on the same side, and an adjusting groove 81 runs through the adjusting member 80. The length of the adjusting groove 81 extends along the height direction of the garbage collection seat 8. Fastening bolts 71 are installed on the outer wall of the intercepting frame 7 facing the adjusting groove 81, and fastening nuts 72 are threaded to the ends of the fastening bolts 71. The fastening nuts 72 are used to tighten and fix the garbage collection seat 8 onto the intercepting frame 7.

[0038] The adjusting component 80 can adjust the height of the garbage collection seat 8 up and down, so as to adapt to the garbage interception work of the drainage ditch 1 at different heights, and ensure that the bottom wall of the garbage collection seat 8 fits in close contact with the inner bottom wall of the drainage ditch 1.

[0039] like Figure 2 , Figure 3 As shown, baffles 82 are inclinedly installed on both the front and rear outer walls of the garbage collection seat 8, and the baffles 82 are symmetrically arranged on the front and rear sides of the garbage collection seat 8. The baffles 82 extend upward to the outside of the interception frame 7. The baffles 82 are used to guide the upstream garbage to be discharged more smoothly into the garbage collection seat 8, further improving the interception effect of the upstream garbage.

[0040] The implementation principle is as follows: the mutual insertion and engagement of the plug rod 21 and the plug slot 11 can limit the horizontal displacement of the trench cover 2, thereby improving the stability of the trench cover 2 and enhancing the connection between the trench cover 2 and the drainage ditch 1. The mutual insertion and engagement of the pin rod 30 and the pin hole 10 can lock the trench cover 2 within the drainage ditch 1, preventing the trench cover 2 from detaching from the drainage ditch 1, further improving the reliability of the connection between the trench cover 2 and the drainage ditch 1.

[0041] When it is necessary to release the lock on the trench cover 2, the lifting element 4 is rotated out of the relief groove 200, and then the pin rod 30 is pulled away from the pin hole 10 by the lifting element 4 until the end of the pin rod 30 is moved out of its respective pin hole 10. At this time, the trench cover 2 can be easily removed from the drainage ditch 1. The operation is convenient and quick. The lifting elements 4 on both sides also provide a point of leverage for the construction personnel to facilitate the smooth removal of the trench cover 2. The garbage collection seat 8 intercepts the upstream garbage, thereby effectively preventing the garbage from flowing downward and spreading, ensuring the garbage interception effect.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
