Description

TECHNICAL FIELD

[0001] The present application relates to the field of environmental protection, in particular to the technical field of riverway cleaning device, and particularly relates to a riverbed cleaning system for riverway management. BACKGROUND

[0002] During a long drainage process, the riverbed is continuously raised due to the continuous accumulation of impurities and silt, which affects the drainage capacity of the riverway and the normal functioning of flood control, drainage, irrigation, water supply, navigation and other functions. Therefore, the riverbed needs to be cleaned in a timely manner. In the prior art, a excavator is usually operated manually for cleaning. This cleaning method is not only labor-intensive but also low in efficiency.

[0003] A riverbed silt cleaning assembly is disclosed in Chinese Utility Model Patent No. CN218437244U, which includes a boat plate body and a suction tube.

[0041] The screening assembly includes a first screening plate 103, a second screening plate 104, a storage box 105, and a third screening plate 106. The storage box 105 is detachably installed inside the hull 101.

The third screening plate 106 is positioned below the first screening plate 103, and the second screening plate 104 is inclinedly positioned above the first screening plate 103. There are two second screening plates 104, distributed on both sides of the storage box 105. The first screening plate 103 and the second screening plate 104 each have a first screening hole, and the third screening plate 106 has a second screening hole.

A water pump 102 passes through the second screening plate 104 and the third screening plate 106, with the bottom of the water pump 102 positioned above the bottom of the storage box 105. Figure 5 Its structural composition is clearly visible.

[0042] When the linear motion component is working, such as Figure 6 As shown, the output shaft of motor 108 drives the bidirectional lead screw 107 to rotate. When the bidirectional lead screw 107 rotates, it drives the two mounting brackets 111 on the same side of the hull 101 to move towards each other on the track plate 109. When the position adjustment component is working, if the movement of mounting base 113 needs to be adjusted, the output shaft of motor 210 drives the lead screw 212 to rotate. When the lead screw 212 rotates, it drives the mounting base 113 to move. When the mounting base 113 moves, it drives the first sludge suction component to move, which in turn drives the second sludge suction component, the telescopic component, and the electromagnetic adsorption box 501 to move. When mounting base 3209 needs to rotate, the output shaft of motor 3208 drives the mounting base 3209 to rotate through the connecting shaft on the mounting base 3209, causing the first sludge suction component to rotate around the axis of the output shaft of motor 3208, which in turn drives the second sludge suction component, the telescopic component, and the electromagnetic adsorption box 501 to rotate.

[0043] When the mud suction pipe 204, the second mud suction assembly, the telescopic assembly, and the electromagnetic adsorption box 501 need to rotate around the axis of the mud suction pipe 204, the output shaft of the motor 210 drives the rotating shaft 207 to rotate. The rotating shaft 207 drives the gear 205 to rotate through the gear 206. The gear 205 drives the mud suction pipe 204 to rotate, which in turn drives the telescopic assembly, the second mud suction assembly, and the electromagnetic adsorption box 501 to rotate.

[0044] When the telescopic assembly works, the piston rod of the electric cylinder 302 drives the telescopic pipe two 303 to slide in the telescopic pipe one 301, thereby driving the second mud pumping assembly and the electromagnetic suction box 501 to move. When the connecting barrel 402 and the electromagnetic suction box 501 need to rotate, the output shaft of the motor five 408 drives the gear four 407 to rotate through the mounting shaft, the gear four 407 drives the mounting seat four 405 to rotate through the gear three 406, the mounting seat four 405 drives the connecting barrel 402 to rotate, and the connecting barrel 402 drives the obstacle avoidance unit and the electromagnetic suction box 501 to rotate. When the electromagnetic suction box 501 needs to move, the output shaft of the motor six 410 drives the lead screw three 403 to rotate, and the lead screw three 403 drives the electromagnetic suction box 501 to slide on the connecting barrel 402.

[0045] When the riverbed cleaning system of the present application works, the ship body 101 needs to be driven to move in the river channel by the towing ship. If the riverbed needs to be cleaned, the linear motion assembly is adjusted to drive the position adjusting assembly, the first mud pumping assembly, the second mud pumping assembly, the telescopic assembly and the electromagnetic suction box 501 to move to the position where the riverbed needs to be cleaned. Then the position adjusting assembly drives the first mud pumping assembly, the second mud pumping assembly, the telescopic assembly and the electromagnetic suction box 501 to descend until they descend to the height of the riverbed that needs to be cleaned. Here, the program control assembly is used for control, so that the electromagnet in the electromagnetic suction box 501 is electrified to generate magnetic force, and the electromagnetic suction box 501 rotates to adsorb the metal on the riverbed that can be adsorbed by the magnetic force into the magnetic adsorption port. After a period of magnetic adsorption (the time is set according to actual use), the output shaft of the motor six 410 drives the lead screw three 403 to rotate, and the lead screw three 403 drives the electromagnetic suction box 501 to ascend on the connecting barrel 402. Then the obstacle avoidance unit continues to descend into the silt on the riverbed, and when an obstacle (such as a large stone) is encountered, the obstacle plate 404 cannot continue to descend, the support head 412 is driven by the stirring rod 411 to slide in the sliding groove, and the spring 413 is compressed (the appropriate spring 413 is selected in advance according to the silt condition of the riverbed), when the sensor one 414 contacts the sensor two 415, an alarm signal is generated, and the position adjusting assembly and the gear one 205 are rotated to adjust the angle of the second mud pumping assembly. If no obstacle is encountered, although the spring 413 will be compressed to a small extent under the influence of the silt resistance, because of the elasticity of the spring 413, the sensor one 414 and the sensor two 415 will not contact at this time.

[0046] When the sludge needs to be extracted, the sludge pump on the sludge extraction pipe one 201 is started, and the stirring rod 411 rotates (the rotating principle is referred to the rotating principle of the obstacle avoidance unit), so that the stirring rod 411 can stir the sludge at the same time when the sludge is extracted, so as to facilitate the dispersion of the sludge and efficient extraction. The sludge enters the telescopic pipe two 303 through the sludge extraction pipe four 401, passes through the telescopic pipe two 303 to reach the electric cylinder 302 and then reaches the sludge extraction pipe three 204, and is sequentially introduced into the sludge extraction pipe one 201. Under the blocking of the air permeable baffle, the sludge will not enter the sludge pump, but will fall into the ship body 101 through the sludge extraction pipe two 202. When falling, the sludge falls onto the sieve plate one 103 through the sieve plate two 104, which is inclinedly arranged, and the large pieces of garbage in the sludge that cannot pass through the sieve hole one are left on the sieve plate one 103 through the filtration of the sieve plate one 103 and the sieve plate two 104. The sludge passing through the sieve hole of the sieve plate three 106 makes the water flow below the sieve plate three 106, which is extracted to the river through the water pump on the water extraction pipe 102, thereby completing the classification of different garbage on the riverbed, so that the garbage can be quickly classified after landing.

[0047] After the sludge on the upper layer of the riverbed is cleaned, the second sludge extraction assembly is driven to continue to descend by the position adjusting assembly (the movement principle is referred to the foregoing) to clean the riverbed, so that the riverbed can be cleaned more thoroughly. When different width rivers are used, the width is adjusted by the telescopic assembly to adapt to the cleaning of the riverbed of different rivers and the riverbed at different positions of the same river.

[0048] It should be particularly noted that the start and stop operations of the above-mentioned power elements in the present application are controlled by the program control assembly arranged in the ship body 1, and the program control assembly belongs to conventional control technology, which will not be described here.

[0049] It is undoubtedly that the above is only a limited structure design and working mode of the riverbed cleaning system for river management of the present application, and in addition to this, other feasible structure composition designs and working processes based on the design are also included. In summary, the protection scope of the present application also includes other transformations and substitutions obvious to those skilled in the art.
