Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway bridge construction, and more specifically to a self-locking anti-blocking device for a drain hole in an expressway. Background Art
[0002] Quality control of drainage construction of municipal roads and bridges helps to ensure the strength of pavement materials. If the pavement of roads and bridges is in a water-soaked environment for a long time, the strength performance of the materials will inevitably be reduced, and various diseases will be more likely to occur. Therefore, strengthening the drainage construction of municipal roads and bridges is more critical. Only by applying scientific methods and effectively controlling the quality of drainage construction can it help protect the strength of pavement materials and extend the service life of the pavement.
[0003] The shortcomings of the existing technology: At present, the drainage holes of highway bridges are set as open drainage holes. Garbage scattered by passing vehicles on the road often falls into the drainage holes, especially plastic garbage, domestic garbage, and large particles of construction waste, which are easily blown into the open drainage holes by the wind and vehicles, causing the drainage holes to be blocked. Especially in the rainy season, heavy rainfall cannot be discharged from the bridge deck in time, resulting in long-term water accumulation on the bridge deck, forming erosion damage to the bridge deck. Long-term water accumulation on the bridge deck will cause a major safety hazard to passing vehicles running over the accumulated water. To this end, we propose a self-locking anti-blocking device for highway drainage holes to solve the above problems. Utility Model Content

[0010] Preferably, a baffle is fixedly connected to the upper surface of the sealing ring, and raised blocks are arranged in a ring shape and at equal intervals on the upper surface of the baffle. The raised blocks on the upper surface of the baffle are all adapted to the inner wall of the second drainage hole, and the baffle is cast from rubber material.

[0014] 2. The utility model is provided with a filter plate, which can prevent external debris from entering the interior of the highway drain hole, thereby preventing the highway drain hole from being blocked, and when water flows through the interior of the installation cylinder, the kinetic energy generated by the water flow will drive the propeller to rotate.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solutions in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The self-locking and anti-blocking device for the highway drain hole involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0023] The utility model provides a self-locking anti-blocking device for a drain hole on a highway, comprising a top tube 1, a mounting tube 2 fixedly connected to the lower surface of the top tube 1, a drainage tube 3 fixedly connected to the bottom end of the mounting tube 2, a filter plate 4 provided on the inner wall of the top tube 1, and a sealing ring 5 provided at the bottom end of the drainage tube 3;
[0024] Among them: mounting grooves 201 are equidistantly provided on the side of the mounting cylinder 2, and locking blocks 202 are movably connected to the inner walls of the mounting grooves 201. One end of the locking blocks 202 located on the inner wall of the mounting grooves 201 is fixedly connected to a spring 1 203, and the other end of the spring 1 203 is fixedly connected to the inner wall of the mounting groove 201. First drainage holes 301 are equidistantly provided on the side of the drainage cylinder 3, and second drainage holes 302 are equidistantly provided in a ring-shaped manner on the lower surface of the drainage cylinder 3. When in use, the spring 1 203 will push the locking block 202 through its own elastic force, so that one end of the locking block 202 is offset against the inside of the highway drain hole. By having multiple locking blocks 202 offset against the inside of the highway drain hole, the self-locking fixation of the device is achieved, which is beneficial to improving the stability of the device.
[0025] Furthermore, a scraper 101 is fixedly connected to the top of the inner wall of the top tube 1. The scraper 101 is cross-shaped, and the lower surface of the scraper 101 fits against the upper surface of the filter plate 4. The lower surface of the filter plate 4 is fixedly connected to a driving rod 401. The other end of the driving rod 401 extends to the inner wall of the mounting tube 2 and is fixedly connected to a propeller 402. The side of the driving rod 401 is fixedly connected to a mounting bracket 403 through a bearing. The mounting bracket 403 is fixedly installed on the top of the inner wall of the mounting tube 2. When in use, the filter plate 4 is fixedly connected to the top of the inner wall of the mounting tube 2. It can prevent external debris from entering the interior of the highway drain hole, thereby preventing the highway drain hole from being blocked. When water flows through the interior of the mounting tube 2, the kinetic energy generated by the water flow will drive the propeller 402 to rotate. When the propeller 402 rotates, it will drive the filter plate 4 to rotate through the driving rod 401. When the filter plate 4 rotates, it will scrape off debris attached to the surface of the filter plate 4 through the scraper 101, thereby preventing the filter plate 4 from being blocked, which is conducive to improving the stability of the device.
[0026] When the water level is too high, the second spring 504 will push the top plate 503 downwards to close the second drain hole 302.
[0027] The working principle of the present invention is as follows: when the device is used, the device is inserted into a drain hole on a highway. At this time, the spring 1 203 pushes the locking block 202 by its own elastic force, so that one end of the locking block 202 abuts against the inside of the drain hole on the highway. By a plurality of locking blocks 202 abutting against the inside of the drain hole on the highway, the device is self-locked and fixed, which is beneficial to improving the stability of the device.
[0028] The filter plate 4 is provided to prevent external debris from entering the interior of the highway drain hole, thereby preventing the highway drain hole from being blocked. When water flows through the interior of the installation cylinder 2, the kinetic energy generated by the water flow drives the propeller 402 to rotate. When the propeller 402 rotates, it drives the filter plate 4 to rotate through the driving rod 401. When the filter plate 4 rotates, the scraper 101 scrapes off the debris attached to the surface of the filter plate 4, thereby preventing the filter plate 4 from being blocked, which is conducive to improving the stability of the device.
[0029] Through the first drainage hole 301 and the second drainage hole 302, during use, when the water volume is small, the accumulated water is discharged through the first drainage hole 301. When the water volume is large, the weight of the accumulated water itself will push the sealing ring 5 downward. At this time, the second drainage hole 302 starts to drain. After the drainage is completed, the second spring 504 will push the top plate 503 through its own elastic force, so that the sealing ring 5 drives the baffle 501 to reset, thereby blocking the second drainage hole 302 and completing the self-locking function, thereby improving the flexibility of the device.
