Description

Technical Field

[0001] This utility model belongs to the field of highway maintenance technology, and in particular relates to a system for removing silt from highway subgrade drainage ditches. Background Technology

[0002] Cleaning of roadbed drainage ditches is an important part of highway maintenance. The main function of drainage ditches is to drain surface water within the roadbed area in a timely manner and prevent water accumulation from damaging the highway and roadbed.

[0003] Over time, debris accumulates in drainage ditches, which then flows into the drainage pipes as water flows, causing blockages at the drainage ports. To avoid this blockage, we propose a roadbed drainage ditch silt removal system to solve the problem of blockages in existing drainage ditches. Utility Model Content

[0004] The purpose of this invention is to provide a system for removing silt from roadbed drainage ditches, which filters and cleans debris to prevent blockage of drainage pipes, thereby solving the aforementioned technical problems.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model filters debris flowing down through a filter cover. When cleaning is required, simply rotate the threaded cylinder. The threaded cylinder rotates on the inner surface of the bearing seat and slides on the inner surface of the guide groove through the guide block, causing the threaded rod to move upward, thereby moving the filter cover upward. After moving a certain distance, the debris can be cleaned. By setting the above structure, the debris can be filtered and cleaned, thus avoiding blockage of the drain pipe.

[0012] 2. This utility model features a rotating plate fixedly connected to the surface of the threaded cylinder for rotating the cylinder, which facilitates the operation of the operator and thus facilitates the rotation of the threaded cylinder, thereby driving the up and down movement of the threaded rod.

[0013] 3. This utility model sets the top end face of the initial position of the threaded rod to be flush with the top end face of the drainage ditch, thus avoiding the situation where the top of the threaded rod is too high and obstructs the passage of vehicles on the road.

[0014] 4. This utility model has a scraper fixedly connected to the surface of the connecting plate. When the filter cover moves up and down, it drives the connecting plate to move, thereby scraping and dispersing the sludge accumulated on the inner wall of the drain pipe through the scraper.

[0022] In the following description, embodiments of the silt removal system for roadbed drainage ditches of this utility model will be described with reference to the accompanying drawings. Example

[0023] Figure 1-4 This invention illustrates a roadbed drainage ditch silt removal system according to an embodiment of the present invention. The system is installed inside a drainage ditch 2, which is located on both sides of the top of the roadbed 1. A through hole is formed at the bottom of the inner cavity of the drainage ditch 2, and a drain pipe 12 is embedded and fixedly connected to the inner surface of the through hole. The system includes a support frame 3 fixedly connected to the top of the drain pipe 12. A threaded cylinder 8 is rotatably connected to the top of the inner cavity of the support frame 3 via a bearing seat 7. A threaded rod 9 is threadedly connected to the inner surface of the threaded cylinder 8. Guide blocks 11 are fixedly connected to both sides of the surface of the threaded rod 9. Guide grooves 10, which are adapted to slide and fit the guide blocks 11, are formed on the front and rear sides of the inner cavity of the support frame 3. A filter cover 4 is fixedly connected to the bottom of the guide blocks 11. The filter cover 4 is embedded inside the drain pipe 12. The top end face of the filter cover 4 has a convex edge design, and the surface of the filter cover 4 is a filter screen. A connecting plate 5 with a hollow structure is fixedly connected to the bottom. Multiple scrapers 6 are fixedly connected to the outer surface of the connecting plate 5. The outer surface of the scrapers 6 is in close contact with the inner surface of the drain pipe 12. By fixing the scrapers 6 to the surface of the connecting plate 5, the connecting plate 5 is moved when the filter cover 4 moves up and down. This allows the scrapers 6 to scrape and disperse the sludge accumulated on the inner wall of the drain pipe 12. The filter cover 4 filters the debris flowing down. When cleaning is required, simply rotate the threaded cylinder 8. The threaded cylinder 8 rotates on the inner surface of the bearing seat 7 and slides on the inner surface of the guide groove 10 through the guide block 11, causing the threaded rod 9 to move upward. This moves the filter cover 4 upward. After moving a certain distance, the debris can be cleaned. By setting up the above structure, the debris can be filtered and cleaned, thereby avoiding blockage of the drain pipe. Example

[0024] Figure 1-4This invention illustrates a roadbed drainage ditch silt removal system according to an embodiment of the present invention. The system is installed inside a drainage ditch 2, which is located on both sides of the top of the roadbed 1. A through-hole is formed at the bottom of the inner cavity of the drainage ditch 2, and a drain pipe 12 is embedded and fixedly connected to the inner surface of the through-hole. The system includes a support frame 3 fixedly connected to the top of the drain pipe 12. A threaded cylinder 8 is rotatably connected to the top of the inner cavity of the support frame 3 via a bearing seat 7. A rotating plate for rotating the threaded cylinder 8 is fixedly connected to the surface of the threaded cylinder 8. This arrangement facilitates operation by the operator. The threaded cylinder 8 is threaded to facilitate its rotation, thereby driving the threaded rod 9 to move up and down. The inner surface of the threaded cylinder 8 is threaded with the threaded rod 9. The top end face of the threaded rod 9 at its initial position is flush with the top end face of the drainage ditch 2. By setting the top end face of the threaded rod 9 at its initial position to be flush with the top end face of the drainage ditch 2, the top of the threaded rod 9 is not too high and may obstruct the movement of vehicles on the road. Guide blocks 11 are fixedly connected to both sides of the surface of the threaded rod 9. The front and rear sides of the inner cavity of the support frame 3 are provided with guide grooves 10 that are adapted to slide with the guide blocks 11. The bottom of the guide blocks 11 is fixedly connected to the filter cover 4.

[0025] Working principle: The filter cover 4 filters the debris flowing down. When cleaning is needed, simply rotate the threaded cylinder 8. The threaded cylinder 8 rotates on the inner surface of the bearing seat 7 and slides on the inner surface of the guide groove 10 through the guide block 11, driving the threaded rod 9 to move upward, thereby moving the filter cover 4 upward. After moving to a certain distance, the debris can be cleaned. By setting the above structure, the debris can be filtered and cleaned, thereby avoiding the purpose of clogging the drain pipe. When the filter cover 4 moves up and down, it drives the connecting plate 5 to move, thereby scraping and scattering the sludge accumulated on the inner wall of the drain pipe 12 through the scraper 6. When the filter cover 4 needs to be reset, simply rotate the threaded cylinder 8 in the opposite direction, thereby driving the threaded rod 9 to move downward, and then placing the filter cover 4 on the inner surface of the drain pipe 12.
