Description

Technical Field

[0001] The present invention relates to the field of dredging, and in particular to an irrigation area dredging device and a use method thereof. Background Art

[0002] Canal siltation not only slows water flow but also increases pressure on culverts and dams, leading to damage to water conservancy projects. Furthermore, canal siltation can lead to reduced water flow, shallower water levels, and poorer water quality, negatively impacting agricultural irrigation, the ecological environment, and water supply for people. Over time, canals can accumulate silt containing debris such as sand, rocks, plastic bottles, iron, aquatic plants, and ropes. These pollutants are a significant source of environmental problems. Dredging boats are one of the fastest and most economical ways to clear silt. However, existing dredging boats have difficulty clearing silt. For objects such as stones and bottles that are larger than the filter holes, the boats use a stirring device to mix the silt and debris, and then centrally extract the silt through a sludge suction pipe. This method is difficult to clean in sections, and it cannot effectively clean debris such as plastic bottles, iron metal, aquatic plants, and ropes. Plastic bottles and iron metals pollute the water quality or soil environment during subsequent silt treatment. Large amounts of aquatic plants or ropes may become entangled in the stirring device or block the filter holes, causing damage or wear to the equipment, increasing additional processing costs, and affecting overall efficiency. To this end, we propose an irrigation area dredging device and its use method to solve the above problems. Summary of the Invention

[0018] S2. Water diversion for irrigation area cofferdam construction: Woven bags of clay were used for construction, and excavators were used to build the cofferdam in layers. Areas that could not be filled by the excavators were filled manually. The cofferdam was built above the normal water level and protected with waterproof colored strips. A double layer of woven bags of clay was installed at the toe of the slope for counterpressure to ensure that the cofferdam was watertight.

Discharge of ferromagnetic materials from silt: Stop the dredging boat and drive the fourth cylinder on one side of the plugboard to move the silt-pushing plate to discharge the ferromagnetic materials on the iron-absorbing rod and the silt in the impurity removal mechanism into the sludge collection tank. The three-way valve is reversed to drive the pump on the silt guide pipe to discharge the ferromagnetic materials driven by the silt.

[0023] S7. After the silt in the cofferdam is cleared, the slope protection is maintained by using two levels of slope protection: chain-type vegetation block slope protection and grass slope protection.

[0024] The present invention provides an irrigation area dredging device and a method for using the same. A winch is driven to rotate a connecting plate relative to the connecting plate to adjust the height of a mud bucket. A rotating motor on a rotating mechanism is driven to rotate a rotating seat to adjust the horizontal angle of the mud bucket, thereby increasing the dredging range of the mud bucket.

[0025] The second motor of the winding mechanism is driven to rotate the main shaft so that the water plants or rope are wound around the winding mechanism.

After a period of operation, the mechanism is opened, the dredging vessel stops, and the silt-pushing plate is moved to allow the ferromagnetic material on the iron-absorbing rod and the silt in the debris removal mechanism to be discharged into the sump tank. The three-way valve is then switched to activate the pump on the silt guide pipe, allowing the ferromagnetic material to be discharged along with the silt. This prevents ferrous metals from contaminating the water or soil. The entire device can effectively remove debris such as plastic bottles, ferrous metals, aquatic plants, and ropes, making it suitable for widespread use. BRIEF DESCRIPTION OF THE DRAWINGS

With this structure, a winch 10 is driven to rotate a connecting plate 13 relative to the connecting plate 13 to adjust the height of the hopper 2. The rotating motor on the rotating mechanism 8 is driven to rotate a rotating seat 801 to adjust the horizontal angle of the hopper 2, thereby expanding the dredging range of the hopper 2.

[0046] The second motor 404 of the winding mechanism 4 is driven to rotate the main shaft 401 so that the water plants or rope are wound around the winding mechanism 4. At the same time, the hook shaft 402 of the winding mechanism 4 hits or pushes the large stones and plastic bottles to push the large stones and plastic bottles to the side of the filter port 208 so that the large stones and plastic bottles are on the salvage device 5.

[0047] When the winding mechanism 4 winds around a lot of water plants or rope, the first cylinder 405 is driven to move the winding mechanism 4 horizontally along the mud bucket 2, so that the winding mechanism 4 is located on the side of the second row of forks 502, so that the blades 5022 abut against the blades 5022 of the second row of forks 502, so that the blades 5022 cut the water plants or rope, and the cut debris falls on the first row of forks 501.

The salvage device 5 moves back and forth to discharge the debris out of the mud bucket 2.

[0048] The screw rod 302 of the conveying mechanism 3 is driven to move the U-shaped scraper 303 , which is then driven to insert the hanging plate 304 , and the screw rod 302 is rotated in the opposite direction to allow the hanging plate 304 to transport the debris to the dredging vessel 1 .

Simultaneously, the hook shaft 402 of the winding mechanism 4 strikes or pushes large rocks or plastic bottles toward the filter port 208, where they are trapped on the salvage device 5. This prevents large amounts of aquatic plants or rope from becoming entangled in the agitator or clogging the filter holes, thus preventing damage or wear to the equipment, reducing additional processing costs, and improving overall efficiency.

[0057] In the preferred embodiment, the salvage device 5 includes a first row of forks 501, a second row of forks 502 and two racks 503.

[0063] Example 2:

[0064] Further explanation is given in conjunction with Example 1: A method for using a silt removal device in an irrigation area includes the following steps: cleaning the main canal in the irrigation area: clearing the slope protection, transplanting or felling trees, and clearing tree roots and weeds on the slope protection;

[0065] Water diversion for irrigation area cofferdam construction: Woven bags of clay were used for construction, and excavators were used to build the cofferdam in layers. Areas that could not be filled by the excavators were filled manually. The cofferdam was built above the normal water level and protected with waterproof colored strips. A double layer of woven bags of clay was installed at the slope foot for counterpressure to ensure that the cofferdam was watertight.

[0066] Drainage within the cofferdam: Use a submersible pump to pump out the water from the main channel in the desilting section until the silt at the bottom of the main channel is exposed, which facilitates subsequent desilting operations;

[0067] The dredging vessel 1 is driven to the silt in the cofferdam, and the winch 10 and the rotating mechanism 8 are driven to adjust the horizontal angle and height of the mud bucket 2; the winding mechanism 4 is driven to wind the weeds and the rope mechanism in the silt that cannot pass through the filter port 208 around the winding mechanism 4, and the winding mechanism 4 is moved to cut the weeds through the second row of forks 502 of the salvage device 5;

[0068] Mud removal: driving the salvage device 5 to transport the debris that cannot pass through the filter port 208 and the objects on the cutting and winding mechanism 4 to the collecting box 9 through the conveying mechanism 3, and the impurity removal mechanism 6 absorbs the ferromagnetic substances in the sludge;

[0069] Discharge of ferromagnetic substances from silt: Stop the dredging vessel 1 and drive the fourth cylinder on the side of the plug plate 207 to move the silt pushing plate 603 so that the ferromagnetic substances on the iron suction rod 602 and the silt in the impurity removal mechanism 6 are discharged into the sludge collecting tank 7. The three-way valve 11 is then switched to drive the pump on the silt guide pipe 12 so that the ferromagnetic substances are discharged along with the silt.

[0070] After the silt within the cofferdam is cleared, the slope protection is maintained using two levels of slope protection: interlocking plant blocks and grass-planted slope protection. After the slope protection is refined, slope protection construction begins. The first level of slope protection utilizes interlocking plant blocks, with a non-woven geotextile and sand and gravel cushion layer serving as a filter layer from bottom to top. The first level of slope protection is manually laid from channel bottom to bottom. Due to the interlocking structure between the interlocking plant blocks, the interlocking plant blocks are laid in a single direction, from side to side. After the interlocking plant blocks are installed, soil is evenly spread between the plant blocks. Fertilizer, auxin, and adhesive are then mixed and applied to the surface, followed by hydraulic seeding. The first level of slope protection is capped with concrete using wooden formwork. The capping construction is consistent with the plant block protection, with expansion joints inserted every 15-20 meters. The second level of slope protection adopts grass planting, and the grass seeds are hydraulically sprayed on the slope. After the spraying is completed, it is covered with non-woven fabric to prevent rain erosion. The germination coverage rate can reach more than 90% in 2 months. After the lawn is formed, the number of watering can be gradually reduced.

The embodiments and features in the embodiments of this application may be arbitrarily combined with each other unless they conflict. The scope of protection of the present invention shall be the technical solutions described in the claims, including equivalent replacements of the technical features of the technical solutions described in the claims.
