Description

Technical Field

[0001] The present invention relates to the technical field of water silt removal, and in particular to a water silt removal device for substandard water bodies. Background Art

[0002] Sediment desilting is a common practice in the management of rivers, lakes, and oceans. The process involves draining the water from the body, excavating and cleaning the sediment, and then introducing water back into the water. Large-scale desilting projects completely alter the aquatic habitat, and the restoration and reconstruction of the aquatic ecosystem takes a long time. Therefore, timely cleaning of heavily contaminated sediment in the early stages of substandard water bodies, especially those with black and odorous water or algal blooms, is crucial for preventing and controlling substandard water pollution.

[0003] Currently, most of the water dredging devices / equipment used for black and smelly water bodies that do not meet the standards only have the functions of sucking and storing silt (such as the Chinese utility model patent with application number 202320318326.3, named "A River Dredging Device"), but do not have the functions of dredging, filtering, and external transportation, which brings great inconvenience to the dredging work.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be further specifically described below through examples and in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1-13 As shown, this embodiment is used for water dredging of substandard rivers, comprising: a dredging vessel hull 1, a silt cleaning unit 2, a filtering unit 3, a pushing unit 4, a transport unit 5 and a folding bridge unit 6;

[0033] A sludge cleaning unit 2 is fixed on the bracket at the bow position of the dredging boat hull 1, and the sludge cleaning unit 2 is arranged on the side of the dredging boat hull 1. A sludge discharge pipe 205 is provided in the sludge cleaning unit 2, and the sludge discharge pipe 205 is fixed on the column of the dredging boat hull 1. A filtering unit 3 is provided below the sludge discharge pipe 205, and the filtering unit 3 is fixed on the dredging boat hull 1. A transport unit 5 is provided behind the filtering unit 3. The four universal wheels 503 in the transport unit 5 are stuck in the groove of the folding bridge unit 6. A pushing unit 4 is provided on the side of the transport unit 5. After the transport unit 5 is full of silt, the pushing unit 4 will push the transport unit 5 to move and provide it with power. The pushing unit 4 is fixed on the protruding bracket of the dredging boat hull 1, and the folding bridge unit 6 is fixed at the stern position of the dredging boat hull 1 and can be folded and unfolded at any time;

[0034] When the dredging ship hull 1 moves to the location where dredging is required, the sludge cleaning unit 2 stirs the sludge and sucks it into the sludge discharge pipe 205, and then the sludge is discharged from the sludge discharge pipe 205 into the filter unit 3. The filter unit 3 removes the moisture in the sludge and transfers the remaining sludge to the transport unit 5. When the transport unit 5 is full of sludge, the folding bridge unit 6 is manually cooperated to open the folding bridge unit 6, and then the pushing unit 4 pushes the transport unit 5 to move an end distance on the folding bridge unit 6. Then the transport unit 5 moves to the ground by its own kinetic energy and dumps the sludge onto the ground beside the river channel or onto a transport vehicle.

[0035] In an optional implementation of the embodiment of the present invention, Figure 3-6 As shown, the sludge cleaning unit 2 includes: a screw moving subunit 201, an electric cylinder 202, a shielding cylinder 203, a sludge suction pump 204, a sludge discharge pipe 205, a motor A206, a fixed ring 207, a fixed sleeve 208, a stirring blade 209 and an annular internal gear 210;

[0036] The screw moving subunit 201 is fixed on the hull 1 of the dredging vessel through a bracket, and two electric cylinders 202 are fixed on the slider of the screw moving subunit 201. The telescopic end of the electric cylinder 202 is fixed to the top of the shielding cylinder 203, and a mud suction pump 204 is fixed in the middle of the shielding cylinder 203. The mud suction pump 204 extends into the interior of the shielding cylinder 203, and the mud outlet of the mud suction pump 204 is fixed to the mud discharge pipe 205. A fixed ring 207 and a fixed sleeve 208 are fixed to the interior of the shielding cylinder 203. The motor A206 is fixed to the top of the shielding cylinder 203, and the motor shaft of the motor A206 passes through the shielding cylinder 203 and the fixed ring 207 and a horizontal The bevel gears are fixed together, and a plurality of transverse bevel gears and vertical bevel gears are rotatably mounted on the fixed ring 207. Each transverse bevel gear is respectively meshed with a vertical bevel gear. An annular internal gear 210 is rotatably mounted on the fixed ring 207. The annular internal gear 210 is meshed with all the transverse bevel gears. Each vertical bevel gear is connected to a stirring blade 209 group through a belt. Each stirring blade 209 group includes two stirring blades 209. The stirring blade 209 is rotatably mounted on the fixed sleeve 208. The stirring blade 209 is detachable. When one of the stirring blades 209 is damaged, only one stirring blade 209 can be replaced.

[0037] During the dredging process, the lead screw moving subunit 201 first drives the electric cylinder 202, the shielding cylinder 203 and the dredge pump 204 to move left and right, thereby adjusting the dredge at different positions for cleaning. Then, the electric cylinder 202 pushes the shielding cylinder 203 and the dredge pump 204 down into the water body. Then, the motor A 206 is started to drive the stirring blade 209 to rotate, stirring the dredge to break up the agglomerated dredge. After the stirring is completed, the dredge pump 204 sucks the dredge into the dredge discharge pipe 205.

[0038] The function of the shielding cylinder 203 is to prevent other floating objects on the water surface from entering the mixing area when the sludge is being stirred, thereby damaging the mixing blade 209 .

[0039] In an optional implementation of the embodiment of the present invention, Figure 7-8 As shown, the filter unit 3 includes: a hydraulic cylinder A301, a water storage tank 302, a water outlet pipe 303, a conveyor belt 304, a filter box 305 and a rotating shaft 306;

[0040] The bottom of the hydraulic cylinder A301 is hinged to the hull 1 of the dredging vessel. The telescopic end of the hydraulic cylinder A301 is fixed to the filter box 305. The water storage tank 302 is fixed to the hull 1 of the dredging vessel. The end of the water storage tank 302 is rotatably mounted with a rotating shaft 306. The rotating shaft 306 is fixed to the end of the filter box 305. The side of the water storage tank 302 is provided with an opening, and the opening is fixed to the water outlet pipe 303.

[0041] The sludge will fall from the sludge discharge pipe 205 into the filter box 305, and the sludge will be filtered by the filter box 305, and the muddy water will leak into the water storage tank 302, and flow into the water body through the outlet pipe 303. When the filtration is completed, the hydraulic cylinder A301 will lift the filter box 305 and dump the sludge therein onto the conveyor belt 304, and the conveyor belt 304 will carry the sludge to the next link.

The middle position of the push plate 403 is slidably mounted on the frame of the screw slider group 401.

[0044] The silt will enter the transport unit 5 along with the transmission of the conveyor belt 304. Since the silt is heavy, in order for the transport unit 5 to leave, the screw slider group 401 needs to drive the push plate 403 to push the transport unit 5.

[0045] In an optional implementation of the embodiment of the present invention, Figure 10-11 As shown, the transport unit 5 includes: a box 501, a turnover box 502, universal wheels 503 and a hydraulic cylinder B504;

[0047] The four universal wheels 503 under the box 501 drive the box 501 to move in the groove of the folding bridge unit 6. After the box 501 moves to the land, the hydraulic cylinder B504 is extended and retracted to drive the flip box 502 to flip, so that the silt inside the flip box 502 is poured onto the land or other vehicles for transporting silt.

[0048] In an optional implementation of the embodiment of the present invention, Figure 12-13 As shown, the folding bridge unit 6 includes: a motor B601, a winding wheel 602, a bottom plate 603, a column 604, a pulley 605, a wire rope 606, a first folding plate 607, a second folding plate 608, a third folding plate 609, a fourth folding plate 610, a first connecting rod 611, a second connecting rod 612, a supporting claw 613 and a connecting plate 614;

[0049] The bottom plate 603 is fixed on the hull 1 of the dredging boat. Two columns 604 are fixed on the bottom plate 603. A motor B601 is fixed to the bottom of each column 604. The motor shaft of the motor B601 passes through the column 604 and is fixed to the winding wheel 602. A pulley 605 is rotatably installed on the top of the column 604. A wire rope 606 is wound around the winding wheel 602. The wire rope 606 passes through the pulley 605 in the middle and is finally fixed to the second connecting rod 612. The first folding plate 607 is fixed on the bottom plate 603. The second folding plate 608 and the front end of the first connecting rod 611 are rotatably installed on the bottom plate 603.

[0050] In order to allow the transport unit 5 to leave the dredging ship hull 1 and run to land, the motor B601 drives the winding wheel 602 to rotate, so that the winding wheel 602 drives the wire rope 606 to reel in and release the line, and then pulls the second connecting rod 612. Since the second connecting rod 612 and the connecting plate 614 are fixed, the second folding plate 608, the third folding plate 609 and the fourth folding plate 610 will be driven to fold or spread flat on land at the same time. When spread flat on land, the support claw 613 will first contact the ground, and the claw on the support claw 613 will be inserted into the ground, so that it is firmly fixed to the ground.
