Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, specifically dredging equipment for river regulation projects. Background Technology

[0002] Silt deposited in river channels is caused by a variety of factors, the main ones being: River water carries large amounts of particulate matter such as silt and gravel during its flow. These particles are transported by the water flow and deposited in areas where the flow slows or stagnates, forming silt. The geological conditions along the river's course also influence silt formation. For example, weathering products of rocks, soil erosion, and riverbank scouring all contribute to the entry of more particulate matter into the river channel. Human activities are also a significant cause of silt formation.

[0003] A search revealed that this utility model relates to a dredging device for river regulation projects, with Chinese patent document number CN 222758988 U. This environmentally friendly dredging device is mounted on a hull, with a silt-piercing section at the bottom of the hull. The silt-piercing section includes: a first height adjustment component longitudinally positioned at the bottom of the hull; a piercing gear rotatably connected to the telescopic end of the first height adjustment component, the teeth of which strike the silt to create cracks; and a piercing gear drive unit for driving the piercing gear to rotate, comprising: a transmission gear coaxially connected to the piercing gear; a rack longitudinally positioned below the bottom of the hull and meshing with the transmission gear; and a reciprocating assembly longitudinally positioned on the hull and fixedly connected to the rack, used to move up and down via the reciprocating assembly to drive the transmission gear to rotate. This utility model improves dredging efficiency and enables rapid dredging of rivers.

[0004] The dredging equipment in the aforementioned patent still has certain shortcomings. In actual use, the existing dredging equipment for river regulation mostly uses excavators and wheelbarrows to dredge large rivers, while for small rivers, the main dredging method is still manual excavation and transportation of silt. This is time-consuming, labor-intensive, and the overall dredging rate is slow, which cannot meet the dredging needs of users. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides dredging equipment for river regulation projects. It solves the problem that existing dredging equipment for river regulation often uses excavators and wheelbarrows for large rivers, while for small rivers, the main dredging method is still manual excavation and transportation of silt. This is time-consuming, labor-intensive, and has a slow overall dredging rate, which cannot meet the dredging needs of users.

[0006] This utility model provides the following technical solution: a dredging equipment for river regulation projects, including a floating hull, wherein a dredging suction component is provided on the floating hull, and a silt dispersion component is provided on the bottom side of the dredging suction component;

[0007] The dredging and suction assembly includes a suction pump located on the top side of the end of the floating vessel. The bottom side of the suction pump is fixedly connected to the floating vessel via a mounting base plate. The input end of the suction pump is connected to a buffer pipe, and two suction pipes are symmetrically connected to the side of the buffer pipe. Each suction pipe has a dredging cover at its bottom end, and the output end of the suction pump is connected to a sewage discharge pipe.

[0008] The sludge dispersion assembly includes fixed connecting plates symmetrically fixed on both sides of the end of the floating vessel. Each fixed connecting plate has an installation slot at its end. A connecting crossbar is provided between the two fixed connecting plates. The end of the connecting crossbar passes through the installation slot. Two connecting collars are symmetrically fitted at both ends of the connecting crossbar. Two fixing screw sleeves are symmetrically fitted at both ends of the connecting crossbar. A bottom mounting plate is provided on the bottom side of the connecting crossbar. A pulling connecting rod is connected to each connecting collar. The end of each pulling connecting rod is rotatably connected to the side of the bottom mounting plate through a bearing. Several sludge dredging plowshares are uniformly fixed at the bottom end of the bottom mounting plate. Two counterweight plates are provided at the top end of the bottom mounting plate.

[0009] Preferred technical solution 1: Two connecting studs are symmetrically arranged on both sides of the top of the bottom mounting plate, and the connecting studs pass through both ends of the counterweight plate.

[0010] Preferred technical solution 2: The top of each connecting stud is fitted with a connecting nut, and two limiting brackets are symmetrically fixed on the side of the bottom mounting plate.

[0011] Preferred technical solution 3: A filter screen is provided on the bottom side of the sludge suction hood.

[0015] Preferred technical solution five: A limiting groove is provided at the top of the limiting frame, and all suction tubes pass through the limiting groove.

[0016] This design allows the suction pipe to be safely placed on the side of the dredging plowshare through the limiting groove.

[0017] Compared with existing technologies, this utility model provides dredging equipment for river regulation projects, which has the following beneficial effects: This utility model has a dredging suction component and a silt dispersion component installed at the end of the floating vessel. The suction pump in the dredging suction component can suck up the silt in the river through the dredging hood and discharge it into the floating vessel's storage compartment through the sewage pipe, thus completing the dredging operation. The bottom mounting plate of the silt dispersion component has evenly arranged dredging plowshares at its bottom, which can plow and disperse the silt attached to the bottom of the river as the floating vessel moves. The limiting frame can limit the suction pipe on the dredging hood, so that the dredging hood is located on the side of the dredging plowshares, which can better suck up the dispersed silt. This device can quickly suck up the silt in the river into the floating vessel's storage compartment, thereby completing the cleaning operation of the obtained silt. This device can adapt to small rivers, speed up the silt cleaning efficiency, effectively reduce the labor intensity of workers, and better meet the dredging needs of users.

[0025] Please see Figure 1-4 ,

[0026] Example 1: Dredging equipment for river regulation projects includes a floating hull 1, a dredging and suction assembly 2 installed on the floating hull 1, and a silt dispersion assembly 3 installed on the bottom side of the dredging and suction assembly 2.

[0027] The dredging and suction assembly 2 includes a suction pump 201 installed on the top side of the end of the floating vessel 1. The bottom side of the suction pump 201 is fixedly connected to the floating vessel 1 through a mounting base plate 202. The input end of the suction pump 201 is connected to a buffer pipe 203. Two suction pipes 204 are symmetrically connected to the side of the buffer pipe 203. The bottom end of each suction pipe 204 is provided with a dredging cover 205. The output end of the suction pump 201 is connected to a sewage discharge pipe 206.

[0028] The sludge dispersion component 3 includes fixed connecting plates 301 symmetrically fixed to both sides of the end of the floating vessel 1. Each end of the fixed connecting plate 301 has a mounting slot 302. A connecting crossbar 303 is provided between the two fixed connecting plates 301. Each end of the connecting crossbar 303 passes through the mounting slot 302. Two connecting collars 304 are symmetrically fitted at both ends of the connecting crossbar 303. Two fixing screws 305 are symmetrically fitted at both ends of the connecting crossbar 303. A bottom mounting plate 306 is provided on the bottom side of the connecting crossbar 303. Pulling devices are connected to each of the connecting collars 304. The connecting rod 307 is pulled and its end is rotatably connected to the side of the bottom mounting plate 306 through bearings. Several dredging plowshares 308 are evenly fixed at the bottom end of the bottom mounting plate 306. Two counterweight plates 309 are provided at the top of the bottom mounting plate 306. Two connecting studs 310 are symmetrically provided on both sides of the top of the bottom mounting plate 306. The connecting studs 310 pass through both ends of the counterweight plates 309. The top of the connecting studs 310 is fitted with connecting nuts 311. Two limit brackets 312 are symmetrically fixed on the side of the bottom mounting plate 306.

[0029] Example 2: The difference between this example and Example 1 is that a filter screen is provided on the bottom side of the sludge suction hood 205.

[0030] It effectively prevents large particles of impurities in the sludge from being sucked in.

[0031] Example 3: The difference between this example and Example 1 is that the ends of the connecting column 303 are all provided with threads, and the fixing screw sleeve 305 is engaged with the threads on the connecting column 303.

[0032] This allows the fixing screw sleeve 305, which is fitted onto the connecting crossbar 303, to fix the connecting crossbar 303 to the fixing connecting plate 301.

[0033] Example 4: The difference between this example and Example 1 is that the top of the limiting frame 312 is provided with a limiting groove, and the suction tubes 204 all pass through the limiting groove.

[0034] This allows the suction tube 204 to be safely placed on the side of the dredging plow 308 through the limiting groove.

[0035] In this embodiment, existing dredging equipment for river regulation mostly uses excavators and wheelbarrows for dredging large rivers, while for small rivers, the main dredging method is still manual excavation and transportation of silt. This is time-consuming, labor-intensive, and the overall dredging rate is slow, which cannot meet the dredging needs of users.

[0036] In summary, in specific implementation, in order to make the work more convenient for cleaning the silt at the bottom of small river channels, and at this time there is still a certain depth of water flow in the river channel, so that the floating boat 1 can float on the water surface, a dredging and suction component 2 and a silt dispersion component 3 are set at the end of the floating boat 1. The bottom mounting plate 306 in the silt dispersion component 3 is rotatably connected to the connecting crossbar 303 by pulling the connecting rod 307.

[0037] The connecting column 303 is fixed to the floating vessel 1 by the fixed connecting plate 301. By evenly arranging several dredging plowshares 308 at the bottom of the bottom mounting plate 306, the dredging plowshares 308 can fit against the bottom of the river when the floating vessel 1 is in motion. This allows the dredging plowshares 308 to plow the silt at the bottom of the river as the floating vessel 1 moves, thus better dispersing the silt attached to the bottom and clearing larger obstacles.

[0038] Simultaneously, the suction pump 201 is activated, allowing it to pump the silt dispersed by the sludge plow 308 through the sludge suction cover 205 on the suction pipe 204. This facilitates the suction and cleaning of the silt. The pumped silt is then injected into the hold of the floating vessel 1 through the sewage pipe 206 for temporary storage, which facilitates the subsequent transfer of the silt.

[0039] The device disperses the silt at the bottom of the riverbed using the dredging plowshare 308 in the silt dispersion component 3, and then, under the suction of the suction pump 201, the silt in the riverbed can be quickly pumped into the floating hull 1 by the sludge suction hood 205 in the dredging suction component 2, thereby completing the silt cleaning operation. This device can adapt to small rivers, speed up the silt cleaning efficiency, effectively reduce the labor intensity of workers, and better meet the silt cleaning needs of users.
