Description

A water retaining earth wall drainage structure for water conservancy projects

Technical Field

The utility model relates to the technical field of water conservancy projects, and more specifically to a water retaining earth wall drainage structure of a water conservancy project.

Background Art

Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Retaining walls are one of the ways. Gravity retaining walls refer to walls that rely on their own weight to resist the lateral pressure of the soil. Gravity retaining walls can be built with stone or concrete, and are generally made into simple trapezoids.

Chinese Patent Authorization Announcement No.: CN215906682U provides a drainage structure for a retaining wall of a water conservancy project. The solution drives a scraper to move through a cleaning mechanism to scrape off other garbage remaining on the filter net to prevent other garbage from adhering to the filter net, thereby improving the drainage efficiency. Through the fan-shaped gear, when opening the baffle, the upper baffle can be opened first, and the water is discharged from the upper drainage hole first. When the drainage hole is blocked, the drainage hole is blocked from the bottom first, so that drainage can be carried out from top to bottom in sequence, thereby controlling the water level.

However, this solution uses a pair of scrapers to scrape off the garbage trapped on the filter. This arrangement will cause the scraped garbage to fall back into the water, polluting the water source, and the garbage that falls into the water may quickly adhere to the filter again under the impact of the water flow, reducing the cleaning effect. Therefore, a water retaining earth wall drainage structure for a water conservancy project is proposed to address the above problems.

Example:

Please refer to Figures 1-2, a drainage structure of a retaining earth wall of a water conservancy project includes a wall 1, a collecting trough 2 is opened at the edge of the upper end of the wall 1, a plurality of drainage holes are opened at one end of the wall 1, and a filter screen 3 is installed at the outer end of the drainage hole, a pair of limiting plates 4 are inlaid at one end of the wall 1, and the plurality of filter screens 3 are all located between the pair of limiting plates 4, a cleaning component 5 is arranged on one side of the limiting plate 4, the cleaning component 5 includes a bracket 501 and a cleaning plate 502, a sliding groove is opened at one end of the limiting plate 4, the bracket 501 and the cleaning plate 502 are both slidably connected to the sliding groove, and the cleaning plate 502 abuts against the wall 1.

Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Building retaining earth walls is one of the ways. Retaining earth walls can be built with stone or concrete, and are generally made into simple trapezoids. Existing retaining earth walls will choose to open drainage holes on the wall surface that are connected to the rear soil, so that the water in the soil can be discharged to the reservoir through the drainage holes to avoid soil loosening caused by excessive water accumulation in the soil. Garbage in the water flow may enter the drainage holes and cause the drainage holes to be blocked. Therefore, this solution installs a filter 3 on the drainage hole to block the garbage, but the garbage is retained in the filter. The net 3 will still cause the filter 3 to be blocked, so the present solution is provided with a cleaning component 5 on one side of the wall 1, and the user can regularly control the bracket 501 to move upward through the servo motor 506, and the bracket 501 drives the cleaning plate 502 to slide on the limit plate 4. During the sliding process of the cleaning plate 502, the garbage trapped on multiple filter screens 3 can be scraped away and transported to the top of the wall 1, so that the garbage finally falls into the collection trough 2 and is collected. Such a setting can effectively prevent the filter 3 from being blocked by garbage, ensure the drainage efficiency of the drainage hole, and also prevent the garbage from returning to the reservoir, thereby protecting the water quality.

Please refer to Figure 2, the cleaning component 5 also includes a pair of mounting blocks 505, the pair of mounting blocks 505 are both installed on the upper end of the wall 1, and a servo motor 506 is installed on the mounting block 505. The pair of servo motors 506 are symmetrical to each other, and the output ends of the pair of servo motors 506 are respectively fixedly connected to rollers 507 and cams 508, and ropes are wrapped around the outer ends of the rollers 507. The end of the rope away from the rollers 507 is fixedly connected to the bracket 501, and a pair of limiting columns 503 are fixedly connected to the bottom end of the cleaning plate 502, and the limiting columns 503 are slidably connected to the bracket 501.

When the staff needs to clean the garbage on the filter screen 3 through the cleaning plate 502, the servo motor 506 equipped with the roller 507 is started to rotate, driving the roller 507 to reel in the rope, so that the rope pulls the bracket 501 to move upward, and then the bracket 501 pushes the cleaning plate 502 to move upward. During the upward movement of the bracket 501 and the cleaning plate 502, they both slide in the sliding groove on the limiting plate 4, wherein the cleaning plate 502 is in contact with the surface of the wall 1 throughout the entire process, which can effectively scrape off the garbage trapped on the filter screen 3. After the cleaning plate 502 moves to the top of the limiting plate 4, the position of the cleaning plate 502 is higher than the collecting tank 2. Due to the inclined setting of the cleaning plate 502, the garbage in the cleaning plate 502 will slide from the cleaning plate 502 into the collecting tank 2 at this time, thereby realizing the concentration of garbage, which can facilitate the staff to centrally process the garbage.

Please refer to FIG. 3 , a spring 504 is sleeved on the outer end of the limiting column 503 , and both ends of the spring 504 are fixedly connected to the bracket 501 and the cleaning plate 502 respectively.

After the cleaning plate 502 moves to the top of the limiting plate 4, one end of the cleaning plate 502 will abut against the cam 508. In order to prevent the garbage on the cleaning plate 502 from adhering to the inner side of the cleaning plate 502 and being unable to fall off, the present solution is arranged that when the cleaning plate 502 abuts against the cam 508, the servo motor 506 equipped with the cam 508 will automatically start and drive the cam 508 to rotate several circles. During the rotation process, the cam 508 continuously squeezes and pushes the cleaning plate 502, so that the cleaning plate 502 drives the limiting column 503 to rotate. The bracket 501 slides on the cleaning plate 502 and repeatedly squeezes the spring 504. Under the repeated push of the cam 508 and the elastic action of the spring 504, the cleaning plate 502 is vibrated, forcing the garbage in the cleaning plate 502 to fall off quickly during the vibration. When the garbage is cleaned, the staff can start the servo motor 506 equipped with the roller 507 to reverse, so that the roller 507 releases the rope, thereby making the bracket 501 and the cleaning plate 502 slide downward under the action of gravity and return to the original position.

Working principle:

When the garbage on the filter screen 3 needs to be cleaned, the staff can start the servo motor 506 equipped with a roller 507 to rotate, drive the roller 507 to reel in the rope, so that the rope pulls the bracket 501 to move upward, and then the bracket 501 pushes the cleaning plate 502 to move upward. During the upward movement of the bracket 501 and the cleaning plate 502, they both slide in the slide groove on the limit plate 4, wherein the cleaning plate 502 abuts against the surface of the wall 1 throughout the entire process, and can effectively scrape off the garbage trapped on the filter screen 3. After the cleaning plate 502 moves to the top of the limit plate 4, one end of the cleaning plate 502 will abut against the cam 508, and the position of the cleaning plate 502 is higher than the collecting tank 2. At this time, the servo motor 506 equipped with the cam 508 will automatically start and drive The cam 508 rotates several times, and the cam 508 continuously squeezes and pushes the cleaning plate 502 during the rotation process, so that the cleaning plate 502 drives the limiting column 503 to slide on the bracket 501, and repeatedly squeezes the spring 504. Under the repeated push of the cam 508 and the elastic action of the spring 504, the cleaning plate 502 will be vibrated, forcing the garbage in the cleaning plate 502 to fall off quickly during the vibration, and the garbage in the cleaning plate 502 will slide from the cleaning plate 502 into the collecting trough 2, thereby achieving the collection of garbage. Then the staff can start the servo motor 506 equipped with the roller 507 to reverse, so that the roller 507 releases the rope, thereby making the bracket 501 and the cleaning plate 502 slide downward under the action of gravity and return to their original positions.

The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
