It includes a main body with a drainage cover on its front, a filter device fixedly installed on one side of the main body, an adjustment device on one side of the filter device, and a flood control device fixedly installed on one side of the main body. This invention allows for device adjustment during operation. The device is fixed using pins, and its height is adjusted via a hydraulic cylinder and hydraulic rod to control its internal dimensions. Shock-absorbing springs and dampers reduce vibrations generated during height adjustment. Municipal sewage flows into the device through drainage holes and is further filtered by a first and second filter screen to remove impurities and prevent blockages in underground pipes.
[0005] Existing drainage devices for municipal road construction lack flexibility in adapting to different terrains to receive and filter water from various locations, failing to meet the diverse drainage requirements of modern municipal road construction. This results in limitations in their use, and the cited patent documents do not offer solutions to these problems. Therefore, this paper proposes a drainage device for municipal road construction to address these issues. Utility Model Content

[0028] The embodiments of this application are described in detail below with reference to the accompanying drawings; however, this application may be implemented in a variety of different ways as defined and covered below.

[0030] A road drainage device includes a drainage frame 1, a filter assembly 2, and an adjustment mechanism 3.
[0031] The top of the drainage frame 1 is provided with an inlet and the bottom of the drainage frame 1 is provided with a drain outlet. The drain outlet is used to connect to an external drainage pipe. The filter assembly 2 is installed inside the drainage frame 1 and is used to filter impurities in the sewage entering the drainage frame 1.
[0032] The adjustment mechanism 3 is located at the bottom of the drainage frame 1. The adjustment mechanism 3 includes a height adjustment component and an angle adjustment component. The angle adjustment component is located between the height adjustment component and the drainage frame 1. The angle adjustment component is used to adjust the tilt angle of the drainage frame 1, and the height adjustment component is used to adjust the height of the drainage frame 1.
[0033] This application's road drainage device incorporates a filter assembly 2 within the drainage frame 1. This filter assembly 2 filters wastewater entering the drainage frame 1 before discharge, preventing blockages in the external drainage pipes at the bottom of the drainage frame 1. Simultaneously, an adjustment mechanism 3 is installed at the bottom of the drainage frame 1. The adjustment mechanism 3 includes a height adjustment component and an angle adjustment component. The angle adjustment component is located on top of the height adjustment component and connected to the bottom of the drainage frame 1. The height adjustment component allows for height adjustment of both the angle adjustment component and the drainage frame 1, while the angle adjustment component allows for adjustment of the angle between the drainage frame 1 and the height adjustment component. This enables flexible adjustment of both the height and angle of the drainage frame 1, facilitating the overall layout and adjustment of the drainage device to adapt to various drainage conditions and meet the diverse drainage requirements of modern municipal road construction.
[0034] Preferably, please refer to Figure 3 As shown, the height adjustment assembly includes an outer cylinder 31, an inner rod 32, and a locking member 34. The inner rod 32 is slidably disposed inside the outer cylinder 31 along the vertical direction. A locking through hole is provided on the side wall of the outer cylinder 31. A plurality of limiting holes 33 are provided at intervals along the vertical direction on the side wall of the inner rod 32. The locking member 34 is used to pass through the locking through hole and then insert into one of the limiting holes 33 to lock and limit the inner rod 32 and the outer cylinder 31.
[0035] It is understandable that the inner rod 32 can be raised and lowered within the outer cylinder 31, and after the inner rod 32 is adjusted to a certain height, it can be locked and limited by the locking member 34. Specifically, the locking member 34 passes through the locking through hole on the side wall of the outer cylinder 31 and is inserted into the limiting hole 33 on the inner rod 32, thereby realizing the locking and limiting of the inner rod 32 and the outer cylinder 31. The overall operation is very simple and facilitates the rapid adjustment of the overall height of the height adjustment component, so as to quickly change the height of the drainage frame 1.
[0036] Optionally, the locking element 34 can be made of bolts or screws, which can reduce the overall procurement cost of the device and facilitate maintenance and replacement.
[0037] Preferably, please refer to Figure 3 As shown, the height adjustment assembly also includes a limiting sleeve 35. Two locking through holes are opened on the side wall of the outer cylinder 31, and the two locking through holes are symmetrically arranged. The limiting hole 33 is a through hole structure. The first end of the locking member 34 is used to pass through the locking through hole on one side, the limiting hole 33 and the locking through hole on the other side in sequence and then connect to the limiting sleeve 35. The second end of the locking member 34 is provided with a limiting platform. The limiting sleeve 35 is used to cooperate with the limiting platform to limit the two ends of the locking member 34.
[0038] Understandably, by using the locking member 34 to pass through the outer cylinder 31 and the inner rod 32 to lock and limit their movement, the stability of the limiting position of the outer cylinder 31 and the inner rod 32 can be ensured, thereby guaranteeing the stable support effect of the height adjustment component on the drainage frame 1 and ensuring the continuous and normal operation of the drainage device. The limiting sleeve 35, fitted onto the first end of the locking member 34, can cooperate with the limiting platform at the second end of the locking member 34 to limit both ends of the locking member 34, reducing slippage and ensuring the overall stability of the height adjustment component.
[0039] In this preferred embodiment, the inner hole of the limiting sleeve 35 is provided with an internal thread, the outer wall of the first end of the locking member 34 is provided with an external thread, and the limiting sleeve 35 is sleeved on the first end of the locking member 34 and threadedly connected to the locking member 34.
[0040] Understandably, the second end of the limiting sleeve 35 and the locking member 34 are connected by threads, which allows the limiting sleeve 35 to be easily adjusted on the locking member 34. Then, the limiting sleeve 35 abuts against the side wall of the outer cylinder 31, and the limiting platform abuts against the outer cylinder 31, thereby limiting the two ends of the locking member 34 and ensuring the stable limiting of the locking member 34 on the inner rod 32.
[0041] Preferably, please refer to Figure 1 and 4 As shown, the road drainage device also includes a rotating component 4. The top surface of the rotating component 4 is provided with a rotating hole, and the bottom end of the adjusting mechanism 3 is inserted into the rotating hole and used to rotate along the rotating hole.
[0042] In this preferred embodiment, the rotating component 4 is disposed at the bottom of the height adjustment component. The rotating component 4 includes a base 42 and a movable block 44. A limiting countersunk hole is provided on the base 42. The limiting countersunk hole is used to limit the bottom end of the outer cylinder 31. A movable groove 43 is provided on the inner wall of the limiting countersunk hole. The movable block 44 is disposed at the bottom of the outer cylinder 31. The movable block 44 is rotatably disposed in the movable groove 43. The movable groove 43 is used to limit the movable block 44.
[0043] It is understandable that the outer cylinder 31 is rotatably connected to the base 42 through the movable block 44, and the outer cylinder 31 can be rotated to adjust the angle. Since the connecting seat 37 of the angle adjustment component can only drive the drainage frame 1 to adjust the angle along a vertical plane, the angle of the connecting seat 37 can be adjusted by rotating the outer cylinder 31 before the angle adjustment component is installed on the drainage frame 1. This allows the drainage frame 1 to be adjusted in different directions, such as adjusting the angle of the drainage frame 1 in the left-right or front-back directions, to adapt to the drainage needs of more different working conditions.
[0044] Preferably, please refer to Figure 4As shown, the road drainage device also includes a flexible pad 41, which is disposed at the bottom of the rotating assembly 4. Specifically, the flexible pad 41 is disposed at the bottom of the base 42.
[0045] Understandably, by setting a flexible pad 41 at the bottom of the base 42, not only can a cushioning effect be provided, but the friction between the base 42 and the bottom surface can also be increased, which is beneficial to improving the overall placement stability of the drainage device.
[0046] Optionally, the flexible pad 41 is made of anti-slip rubber, which can effectively increase its friction with the ground and prevent the drainage device from shaking or shifting.
[0047] Preferably, please refer to Figure 3 As shown, the angle adjustment assembly includes a connecting seat 37 and a rotating shaft 36. The connecting seat 37 includes a body, the top of which is connected to the bottom of the drainage frame 1. The bottom of the body is provided with connecting plates at intervals. The rotating shaft 36 is rotatably inserted into a pre-set mounting hole at the top of the height adjustment assembly. The two ends of the rotating shaft 36 are respectively connected to the connecting plates on both sides of the bottom of the body. The connecting plates have limit screw holes along the direction toward the telescopic rod assembly. The limit screw holes are used to install limit bolts.
[0048] It is understood that the connecting seat 37 is connected to the top of the height adjustment component via the rotating shaft 36. Specifically, the connecting seat 37 is connected to the mounting hole at the top of the inner rod 32 via the rotating shaft 36. The connecting seat 37 can rotate around the mounting hole. The top of the body of the connecting seat 37 is connected to the drainage frame 1, thereby enabling the connecting seat 37 to drive the drainage frame 1 to rotate together and change the angle of the drainage frame 1, so as to adapt to road construction in different terrains, improve the versatility and adaptability of the drainage device, and enhance its practicality.
[0049] Preferably, please refer to Figure 1 and 2 As shown, the filter assembly 2 includes a support member 21 and a filter plate 22. The support member 21 is a frame structure with openings at the top and bottom. The support member 21 is disposed inside the drainage frame 1, and the filter plate 22 is disposed at the bottom of the support member 21.
[0050] It is understandable that the filter plate 22 is installed through the support member 21. The filter plate 22 can filter out the debris that enters the drainage frame 1 and the support member 21, and prevent the drainage hole 27 of the drainage frame 1 and the drainage pipe connected to the bottom from becoming blocked.
[0051] In this preferred embodiment, an inclined support plate is provided inside the drainage frame 1. The support plate is used to support the carrier 21 and the filter plate 22. A drainage hole 27 is provided on the support plate. The filter plate 22 is inclinedly disposed at the bottom of the carrier 21, and the bottom surface of the filter plate 22 abuts against the support plate.
[0052] It is understandable that the support plate is inclined inside the drainage frame 1, and the filter plate 22 inside the bearing member 21 is also inclined accordingly. The support plate supports the filter plate 22, and drainage holes 27 are provided on the support plate. Preferably, multiple drainage holes 27 are arranged at intervals. The whole can realize that after sewage enters the drainage frame 1, it is quickly filtered and drained through the filter plate 22 and drainage holes 27 under the action of gravity, which is beneficial to improving the overall filtration and drainage performance of the drainage device.
[0053] Preferably, please refer to Figure 1 and Figure 2 As shown, a fixing block 23 is provided on the outer side of the side wall of the bearing member 21. A connecting screw hole 24 is provided on the fixing block 23. The connecting screw hole 24 is used to install the connector 25. A fixing groove 26 is provided on the top of the side wall of the drainage frame 1. The fixing groove 26 is used to limit the fixing block 23. A locking screw hole is provided at the bottom of the fixing groove 26. The connector 25 is used to pass through the connecting screw hole 24 and cooperate with the locking screw hole to lock and limit the fixing block 23 in the fixing groove 26.
[0054] Understandably, the support member 21 is engaged with the drainage frame 1 by the fixing block 23, thus facilitating the disassembly and assembly of the support member 21 for subsequent cleaning of the filter plate 22. Simultaneously, after the fixing block 23 is positioned by the fixing groove 26, the connecting member 25 locks and limits the fixing block 23 to the side wall of the drainage frame 1, thereby strengthening the stable connection of the support member 21.
[0055] Optionally, the connector 25 can be made of bolts or screws, which can be easily installed and removed using conventional tools to improve the overall ease of use of the drainage device.
