Description

Technical Field

[0001] The present invention relates to the technical field of road engineering silt removal, and in particular to a municipal road engineering anti-blocking and silt removal device and method. Background Art

[0002] Road engineering refers to the entire process of planning, design, construction, maintenance, and management of roads, as well as the engineering entities involved. Drainage ditches are typically dug along the sides of existing municipal roads. These ditches connect to sewers and are used to drain sewage and rainwater. However, dust from the road surface, mixed with solid and liquid waste, accumulates in the ditches, generating a large amount of sludge that can clog the ditches and hinder drainage.

[0003] In order to prevent roadside drains from being blocked, they need to be cleaned regularly. Existing drains are divided into open channels and culverts. Open channels are easier to clean. You only need to remove the cover on the upper side of the drain and then clean it. Culverts are more inconvenient to clean. They are generally flushed through water pipes. Since a lot of sludge has become hardened, it is difficult to clean it with the impact of water flow alone. The cleaning effect is poor and the efficiency is low. Summary of the Invention

[0015] The present invention also provides a method for preventing blockage and clearing silt in a municipal road project, comprising the following steps:

[0016] S1. Preliminary Survey: Use video acquisition equipment to collect information about the internal conditions of the culvert to determine whether the internal environment of the culvert meets the requirements for vehicle use. At the same time, measure the length, width, and height of the culvert.

[0017] S2. Preliminary treatment: Use a high-pressure water truck to pump water into the culvert to soften and dilute the compacted silt in the culvert. At the same time, flush out some light debris in the culvert so that the vehicle body can move more conveniently in the culvert.

[0018] S3. Cleaning: Open the covers at both ends of the culvert, then place the vehicle body into the culvert. The vehicle moves in the culvert. During its movement, the scraper scoops up the silt at the corners of the culvert, and the first and second rake teeth rake away the silt at the bottom of the culvert. The treated silt is flushed into slurry through the water supply pipe and nozzle, and finally the slurry is sucked away through the sewage pipe and sent out of the culvert.

[0019] S4. Auxiliary traction: When there is a lot of silt in the culvert, tie one end of the wire rope to the traction device and the other end of the wire rope to the hook at the end of the fixed arm. Use the traction device to drag the vehicle body to assist its movement.

[0020] The present invention has the following beneficial effects:

[0021] 1. This municipal road engineering anti-blocking and silt removal equipment and method is provided with a first cleaning mechanism, a second cleaning mechanism, and a third cleaning mechanism on the vehicle body. The first cleaning mechanism is provided with a first rake tooth. The first rake tooth can rake away the silt compacted at the bottom of the ditch. In this way, when the ditch is flushed with high-pressure water flow, the compacted silt can be better cleaned;

[0022] 2. A scraper is provided at the second cleaning mechanism. Since sludge tends to accumulate at the corners of the ditch, scrapers are provided on both sides of the fixed arm. The scrapers can shovel up the sludge at the corners of the ditch. The existence of the scraper enables the device to clean the places in the ditch where sludge is likely to accumulate more specifically, and the cleaning effect is better.

[0023] 3. The second cleaning mechanism is located in front of the first cleaning mechanism. When working, the second cleaning mechanism will first shovel up the silt at the corners of the ditch, then break it up, and then move the silt to the middle of the ditch. Subsequently, the first rake teeth will further process the silt. In this way, the first cleaning mechanism and the second cleaning mechanism jointly process the silt in the ditch, making the subsequent cleaning work simpler and the cleaning effect better.

[0024] 4. The third cleaning mechanism is located on the rear side of the first cleaning mechanism, which includes a first fixed seat. A second rake tooth is provided on the first fixed seat. The second rake tooth is a hollow structure. A water outlet is provided on the second rake tooth. When in use, the second rake tooth is connected to a water supply pipe. After the water enters the second rake tooth, it will be sprayed out through the water outlet. In actual use, the first rake teeth and the second rake teeth complement each other and work together to rake away the silt. At the same time, the silt can be further flushed away through the water outlet at the second rake tooth, and the cleaning effect is better.

[0025] 5. When the vehicle body is moving, the transmission mechanism can be used to drive the second fixed seat to move back and forth. When the second fixed seat moves, it will move with the nozzle and the water supply pipe. In this way, the ditch can be flushed by the movable nozzle, which can achieve a better cleaning effect. At the same time, the second fixed seat will move with the first fixed seat when it moves, and the first fixed seat will move with the second rake teeth. In this way, when the vehicle body is moving, the movement trajectory of the second rake teeth is wavy, which can process more silt and achieve a better cleaning effect.

[0026] 6. The present invention is provided with a first crushing mechanism, which includes a transmission shaft, a stirring wheel and a first guide wheel. During the movement of the vehicle, the first guide wheel will contact the inner wall of the ditch and rotate. Since the first guide wheel and the stirring wheel are fixedly connected to the transmission shaft, when the first guide wheel rotates, the transmission shaft and the stirring wheel will rotate together. When the scraper scoops up the silt, the silt will move along the scraper to the stirring wheel. The stirring wheel can not only crush the scooped silt, but also move the silt on both sides of the ditch to the middle of the ditch, and then the first rake teeth and the second rake teeth are used to process the silt, thereby achieving a better cleaning effect.

When working, the water supply pipe 15 is connected to an external water pipe, and water flows into the water supply pipe 15 and is sprayed out through the nozzle 16. When the vehicle body 1 is moving, the ditch can be flushed through the water supply pipe 15 with the nozzle 16.

[0045] A support seat 18 is provided on the lower side of the fixed arm 3, and a transmission mechanism is provided at the support seat 18. The transmission mechanism includes a fixed shaft 19, a cam 20 is provided in the middle of the fixed shaft 19, and a transmission wheel 21 is provided at one end of the fixed shaft 19. The transmission wheel 21 is fixedly connected to the fixed shaft 19, and a first movable rod 22 is provided in the support seat 18, and one end of the first movable rod 22 is slidably connected to the support seat 18.

[0046] A second movable rod 23 and a slider 24 are provided in the fixed arm 3. The second movable rod 23 is elastically connected to the fixed arm 3 through a second spring 25, and a first protrusion 26 is provided on the lower side of the second movable rod 23. A protrusion 27 is provided on one side of the second movable rod 23. The slider 24 is located on one side of the protrusion 27, and a bevel is provided on one side of the slider 24.

[0047] A fixed shaft 19 is provided at the support seat 18, and a transmission wheel 21 is provided on the fixed shaft 19. When the vehicle body 1 is moving, the transmission wheel 21 will rotate, and the fixed shaft 19 will rotate synchronously with the transmission wheel 21. A cam 20 is provided on the fixed shaft 19, and a first movable rod 22 is provided on the upper side of the cam 20.

[0048] When the vehicle body 1 is moving, the transmission mechanism can be used to drive the second fixed seat 14 to reciprocate. When the second fixed seat 14 moves, it will move with the nozzle 16 and the water supply pipe 15. In this way, the ditch can be flushed by the movable nozzle 16, and a better cleaning effect can be obtained. At the same time, the second fixed seat 14 will move with the first fixed seat 10 when moving, and the first fixed seat 10 will move with the second rake teeth 11. In this way, when the vehicle body 1 is moving, the movement trajectory of the second rake teeth 11 is wavy, which can process more silt and achieve a better cleaning effect.

[0049] A first crushing mechanism is provided on the upper side of the scraper 8, and the first crushing mechanism includes a transmission shaft 30, a stirring wheel 31 and a first guide wheel 32.

[0050] In order to further improve the sludge cleaning effect, the present technical solution also provides a first crushing mechanism at the scraper 8. The first crushing mechanism includes a drive shaft 30, a stirring wheel 31 and a first guide wheel 32. During the movement of the vehicle, the first guide wheel 32 will contact and rotate with the inner wall of the ditch. Since the first guide wheel 32 and the stirring wheel 31 are both fixedly connected to the drive shaft 30, when the first guide wheel 32 rotates, it will rotate with the drive shaft 30 and the stirring wheel 31. After the scraper 8 shovels up the silt, the silt will move along the scraper 8 to the stirring wheel 31. The stirring wheel 31 can not only crush the scooped silt, but also the stirring wheel 31 can move the silt on both sides of the ditch to the middle of the ditch, and then the first rake teeth and the second rake teeth are used to process the silt, so that the cleaning effect is better.

[0051] Example 2

[0052] This example is an explanation based on Example 1. For details, please refer to Figure 2 and Figure 5 A squeezing plate 33 is provided on one side of the scraper 8, and a second connecting rod 34 and a movable column 35 are provided on the upper side of the squeezing plate 33.

[0053] A second protrusion 28 is formed at one end of the second movable rod 23 , and the second protrusion 28 is tapered.

[0054] One end of the movable column 35 is in conflict with the second protrusion 28. When the second movable rod 23 moves, it will move with the second protrusion 28. Under the conflict of the second protrusion 28, the movable column 35 opens to both sides of the fixed arm. When the movable column 35 moves, it will move with the second connecting rod 34 and the extrusion plate 33. A bending portion that bends outward is provided at one end of the extrusion plate 33. In actual use, the extrusion plate 33 can play a guiding role, so that the silt can be better gathered on the scraper 8, which can improve the crushing effect of the stirring wheel 31. At the same time, the extrusion plate 33 is movable. The compacted silt can be squeezed by the extrusion plate 33 to be crushed more thoroughly. In this way, when it is flushed by water, the silt can be more conveniently flushed into mud, thereby facilitating the sewage pipe 2 to suck it out.

[0055] Example 3

[0056] See also Figures 1 to 6 The present invention also provides a method for preventing and clearing silt in a municipal road project, comprising the following steps:

[0057] S1. Preliminary Survey: Use video acquisition equipment to collect information about the internal conditions of the culvert to determine whether the internal environment of the culvert meets the requirements for vehicle use. At the same time, measure the length, width, and height of the culvert.

[0058] S2. Preliminary treatment: Use a high-pressure water truck to pump water into the culvert to soften and dilute the compacted silt in the culvert. At the same time, flush out some light debris in the culvert so that the vehicle body can move more conveniently in the culvert.

[0059] S3. Cleaning: Open the covers at both ends of the culvert, then place the vehicle body 1 into the culvert. The vehicle body 1 moves in the culvert. During its movement, the scraper 8 scoops up the silt at the corners of the culvert, and the first and second rake teeth 7 and 11 rake away the silt at the bottom of the culvert. The treated silt is flushed into slurry through the water supply pipe 15 and the nozzle 16. Finally, the slurry is sucked away through the sewage pipe 2 and sent out of the culvert.

[0060] S4. Auxiliary traction: When there is a lot of silt in the culvert, tie one end of the wire rope to the traction device, and tie the other end of the wire rope to the hook 4 at the end of the fixed arm 3. Use the traction device to drag the vehicle body 1 to assist its movement.

[0061] This technical solution cleans the culvert by providing a vehicle body 1 with a scraper 8, a first rake tooth 7, a second rake tooth 8 and a water supply pipe 15. The scraper 8 can shovel up the silt at the corners of the culvert, and the first rake teeth 7 and the second rake teeth 11 can rake away the silt at the bottom of the culvert. The treated silt can be flushed into mud through the water supply pipe 15 and the nozzle 16 to facilitate its discharge. When there is a lot of silt, auxiliary traction can be used to tow the vehicle body 1. It can be applied to a variety of situations and can quickly and efficiently complete the cleaning of the culvert.

At the same time, flush out some light debris in the culvert so that the vehicle can move more conveniently in the culvert. S3. Cleaning: Open the covers at both ends of the culvert, then place the vehicle body into the culvert. The vehicle moves in the culvert. During its movement, the scraper scoops up the silt at the corners of the culvert, and the first and second rake teeth rake away the silt at the bottom of the culvert. The treated silt is flushed into slurry through the water supply pipe and nozzle, and finally the slurry is sucked away through the sewage pipe and sent out of the culvert. S4. Auxiliary traction: When there is a lot of silt in the culvert, tie one end of the wire rope to the traction device and the other end of the wire rope to the hook at the end of the fixed arm. Use the traction device to drag the vehicle body to assist its movement.
