Description

Technical Field

[0001] This utility model relates to the field of drainage and dredging technology, specifically a dredging device for road drainage projects. Background Technology

[0002] Road drainage engineering is an important part of urban infrastructure, undertaking the important task of draining urban rainwater and sewage, ensuring smooth roads and a clean living environment for residents. However, with the rapid advancement of urbanization and the increase in population density, road drainage systems are facing increasingly severe challenges. Over the long term, drainage ditches often become blocked due to the deposition and siltation of various pollutants. This not only affects drainage efficiency but may also trigger natural disasters such as flooding, threatening the lives and property safety of urban residents.

[0003] Traditional ditch drainage and dredging methods mainly rely on manual shoveling or the use of simple mechanical equipment for dredging. These methods are not only inefficient and require a large investment of manpower and resources, but also often fail to effectively handle hardened silt. This hard silt is difficult to extract directly, which brings great difficulties to the dredging work. Therefore, a dredging device for road drainage projects is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a dredging device for road drainage projects to overcome the deficiencies of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dredging device for road drainage engineering includes a base plate and a storage box fixedly installed on the top of the base plate. A silt breaking mechanism is provided on the left side of the base plate, a flushing structure is provided on the left side of the silt breaking mechanism, and a silt pumping structure is provided between the silt breaking mechanism and the storage box.

[0007] The sludge breaking mechanism includes two hollow plates fixedly installed on the left side of the base plate. A connecting frame is slidably installed inside the hollow plates. Four limiting vertical rods are fixedly installed inside the hollow plates. The connecting frame slides up and down outside the four limiting vertical rods. A breaking cover is fixedly installed at the bottom of the connecting frame. A breaking rod is rotatably installed inside the breaking cover, extending to its back. A first conical tooth located on the back of the breaking cover is fixedly installed outside the breaking rod. A motor is fixedly installed inside the connecting frame near its back. A second conical tooth meshing with the first conical tooth is fixedly installed at the bottom output end of the motor. The sludge pumping structure is located on the right side of the breaking cover. A power component for controlling the lifting and lowering of the breaking cover is arranged between the two hollow plates.

[0008] The beneficial effects of this invention are as follows: By activating the flushing structure, the moisture in the sludge is increased, aiding in its loosening. Simultaneously, the motor drives the second bevel gear to rotate, meshing with the first bevel gear to rotate the breaking rod within the breaking hood, effectively breaking up the sludge. With the flushed water, the hardened sludge is further diluted. At this point, the sludge extraction structure begins operation, easily removing the diluted sludge. Furthermore, as the breaking rod rotates, the power component can also raise and lower the breaking hood and the breaking rod, enabling the device to handle sludge of different depths, thus improving the flexibility and efficiency of sludge treatment. The entire process achieves effective breaking and extraction of the sludge.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the flushing structure includes a water pump installed above the knot-breaking hood. The pump's extraction end is fixedly equipped with a water suction pipe that extends into the storage tank and is close to the bottom of the storage tank. The pump's output end is fixedly equipped with a drain pipe. A long strip nozzle is fixedly installed on the left side of the knot-breaking hood, with the spray direction of the long strip nozzle pointing downwards. The bottom of the drain pipe is fixedly connected to the water inlet of the long strip nozzle.

[0011] Furthermore, the sludge removal structure includes a sludge pump fixedly installed on the top of the base plate. The suction end of the sludge pump is fixedly installed with a telescopic pipe that extends to the bottom of the base plate. A sludge suction hood that extends to the inside of the knot-breaking hood is fixedly installed on the left side of the telescopic pipe. The sludge suction hood is located near the bottom of the knot-breaking hood. A sludge discharge pipe is fixedly installed at the output end of the sludge pump. The discharge end of the sludge discharge pipe faces the inside of the storage tank.

[0012] Furthermore, the power assembly includes a support plate fixedly installed between two open plates, a water pump fixedly installed on the top of the support plate, and three electric push rods fixedly installed inside the support plate. The bottom telescopic ends of the three electric push rods are all fixedly connected to the top of the knot-breaking hood.

[0013] Furthermore, a partition plate is fixedly installed inside the storage box, the water pump pipe is located at the back of the partition plate, and the sewage pipe is located at the front of the partition plate.

[0014] Furthermore, a filter screen is fixedly installed inside the storage box in front of the partition plate. The filter screen is close to the bottom of the storage box. The outside of the partition plate is concave, and the concave part of the partition plate is located below the filter screen. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1, as Figures 1-5 As shown, a dredging device for road drainage engineering includes a base plate 1 and a storage box 2 fixedly installed on the top of the base plate 1. A silt breaking mechanism is provided on the left side of the base plate 1, a flushing structure is provided on the left side of the silt breaking mechanism, and a silt pumping structure is provided between the silt breaking mechanism and the storage box 2.

[0024] Specifically, the sludge breaking mechanism includes two open plates 3 fixedly installed on the left side of the base plate 1. A connecting frame 4 is slidably installed inside the openings of the two open plates 3. Four limiting vertical rods 401 are fixedly installed inside the openings of the two open plates 3. The connecting frame 4 slides up and down outside the four limiting vertical rods 401. A breaking cover 5 is fixedly installed at the bottom of the connecting frame 4. A breaking rod 6 is rotatably installed inside the breaking cover 5, extending to its back. A first conical tooth 7 located on the back of the breaking cover 5 is fixedly installed outside the breaking rod 6. A motor 8 is fixedly installed inside the connecting frame 4 near its back. A second conical tooth 9 that meshes with the first conical tooth 7 is fixedly installed at the bottom output end of the motor 8. A sludge pumping structure is located on the right side of the breaking cover 5. A power component for controlling the lifting and lowering of the breaking cover 5 is provided between the two open plates 3.

[0025] In use, the connecting frame 4 is restricted to rise and fall within the two open plates 3 by the four limit rods 401. When encountering compacted sludge, the flushing structure on the left side of the sludge breaking mechanism is activated. This flushing structure discharges water, increasing the moisture content of the compacted sludge and thus helping to loosen it. Simultaneously, the motor 8 is started to drive the second bevel gear 9 to rotate. During the rotation of the second bevel gear 9, through meshing with the first bevel gear 7, it drives the breaking rod 6 to rotate inside the breaking cover 5. The rotation of the breaking rod 6 is key to breaking up the compacted sludge. It effectively breaks up the sludge, and the flushed water further dilutes the compacted sludge. Subsequently, the sludge suction structure on the right side of the breaking cover 5 starts to operate, easily removing the diluted sludge. In addition, while the breaking rod 6 rotates, the operation of the power component can also drive the breaking cover 5 and the breaking rod 6 inside the breaking cover 5 to rise and fall. This feature enables the device to break up sludge of varying depths, improving the flexibility and efficiency of sludge treatment.

[0026] Example 2, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0027] The flushing structure includes a water pump 10 installed above the clotting hood 5. The pump 10 has a water suction pipe 11 fixedly installed at its extraction end, which extends into the storage tank 2 and is close to the bottom of the storage tank 2. The pump 10 has a drain pipe 12 fixedly installed at its output end. A long strip nozzle 13 is fixedly installed on the left side of the clotting hood 5. The long strip nozzle 13 sprays water downwards. The bottom of the drain pipe 12 is fixedly connected to the inlet of the long strip nozzle 13.

[0028] With this setup, the water pump 10 can draw water stored inside the storage tank 2 through the water pumping pipe 11, and then discharge it into the elongated nozzle 13 through the drain pipe 12. The water inside the elongated nozzle 13 is sprayed downwards, increasing the moisture content of the hardened sludge, which helps to loosen the sludge.

[0029] Example 3, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0030] The sludge removal structure includes a sludge pump 14 fixedly installed on the top of the base plate 1. A telescopic pipe 15 is fixedly installed at the extraction end of the sludge pump 14, extending through to the bottom of the base plate 1. A sludge suction hood 16 is fixedly installed on the left side of the telescopic pipe 15, extending through to the inside of the knot breaking hood 5. The end of the sludge suction hood 16 is close to the bottom of the knot breaking hood 5. A sludge discharge pipe 17 is fixedly installed at the output end of the sludge pump 14, with the discharge end of the sludge discharge pipe 17 facing the inside of the storage tank 2.

[0031] With this configuration, the suction pump 14 can extract the diluted sludge inside the sludge-breaking hood 5 by operating through the telescopic pipe 15 and the suction hood 16. After that, it is discharged into the storage tank 2 for storage through the discharge pipe 17.

[0032] Example 4, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0033] The power assembly includes a support plate 18 fixedly installed between two open plates 3, a water pump 10 fixedly installed on the top of the support plate 18, and three electric push rods 19 fixedly installed inside the support plate 18. The bottom telescopic ends of the three electric push rods 19 are all fixedly connected to the top of the knot-breaking cover 5.

[0034] With this configuration, the three electric push rods 19 can be supported and restricted between the two open plates 3 by the installed support plate 18. The operation of the three electric push rods 19 can drive the breaking cover 5 to rise and fall.

[0035] Example 5, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0036] A partition plate 20 is fixedly installed inside the storage box 2. The water pump pipe 11 is located at the back of the partition plate 20, and the sewage pipe 17 is located at the front of the partition plate 20.

[0037] With this configuration, the interior of the storage box 2 is divided into two spaces by the installed partition plate 20. The space behind the partition plate 20 can store water, and the water pump 11 draws water from the space behind the partition plate 20. The space in front of the partition plate 20 can store sludge, and the sludge discharged by the drain pipe 17 is stored in the space in front of the partition plate 20.

[0038] Example 6, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 5, and its specific details are as follows:

[0039] Inside the storage box 2, a filter screen 21 is fixedly installed in front of the partition plate 20. The filter screen 21 is close to the bottom of the storage box 2. The outside of the partition plate 20 is concave, and the concave part of the partition plate 20 is located below the filter screen 21.

[0040] With this configuration, the sludge enters the storage tank 2 and is filtered by the filter screen 21. The precipitated water falls into the bottom of the filter screen 21 and then passes through the groove of the partition plate 20, which can connect with the water storage space inside the storage tank 2. This allows the water pump 10 to directly pump away the precipitated water when it is running, thus achieving the effect of saving water.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
