River and lake silt environmental protection dredging construction device

Abstract

This invention relates to the field of dredging equipment technology, and in particular to an environmentally friendly dredging construction device for rivers and lakes. The device includes a base, on which a rotating adjustment mechanism is mounted. A gantry frame is mounted at one end of the rotating adjustment mechanism. A conveying mechanism is vertically and movably mounted on the gantry frame, and a mud-collecting mechanism is mounted at the bottom of the conveying mechanism. A negative pressure suction mechanism is mounted on the rotating adjustment mechanism and is connected to the conveying mechanism. The mud-collecting mechanism is semi-enclosed. By using a semi-enclosed mud-collecting mechanism in conjunction with a low-speed cutting component, the mud-collecting mechanism, during operation, covers the silt layer at the bottom of the river or lake, isolating the cutting and crushing area from the external water body. This effectively inhibits the diffusion of silt particles into the surrounding water body, avoiding the problem of large-area turbidity caused by the agitation of traditional high-speed stirring blades. The low-speed cutting component operates at a lower speed, reducing disturbance to the original soil below the silt layer during the cutting process.

Description

Technical Field

[0001] This invention relates to the field of dredging equipment technology, and in particular to an environmentally friendly dredging construction device for rivers and lakes. Background Technology

[0002] The problem of silt deposited in water bodies such as rivers and lakes is becoming increasingly serious. It not only affects the aquatic ecological environment, but also restricts the functioning of navigation channels and flood control. When the siltation is severe, it will greatly reduce the original flood discharge and navigation capacity of the river and cause serious damage to the overall ecological environment of the river. In order to deal with the adverse effects of siltation, dredging operations are widely used as a basic management method.

[0003] Existing equipment for dredging is usually equipped with a high-suction air pump and a fast-moving agitator to stir the bottom of the river. For shallow rivers, less than 3 meters deep, this can easily cause the water to become turbid and generate a lot of noise, which affects the dredging process.

[0004] To address these issues, those skilled in the art have proposed an environmentally friendly dredging device for rivers and lakes. Summary of the Invention

[0005] Therefore, the technical problem to be solved by this invention is that it easily causes water turbidity and generates a lot of noise, which affects the dredging work.

[0006] The above-mentioned technical problems are solved by the following technical solution: This invention proposes an environmentally friendly dredging construction device for rivers and lakes, which includes: A base, on which a rotation adjustment mechanism is provided, and a gantry frame is provided at one end of the rotation adjustment mechanism; A conveying mechanism is vertically and movably installed on the gantry frame, and a mud-removing mechanism is installed at the bottom end of the conveying mechanism; The rotation adjustment mechanism is equipped with a negative pressure suction mechanism, which is connected to the conveying mechanism; The mud-collecting mechanism is semi-enclosed and contains a low-speed cutting component.

[0007] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake silt of the present invention, the rotating adjustment mechanism includes a mounting frame installed on the side wall of the base, a motor installed at one end of the mounting frame, a turntable installed at one end of the motor, the turntable being rotatably mounted on the base, and a pushing component being provided at one end of the turntable.

[0008] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake siltation of the present invention, the pushing component includes an electric cylinder installed on the side wall of the turntable, a central fixing plate is installed at one end of the electric cylinder, the gantry frame is installed on the fixing plate, and the negative pressure suction mechanism is installed on the outer shell of the electric cylinder.

[0009] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake silt of the present invention, the gantry frame has a strip groove, an electric slide rail is provided on the inner side of the strip groove, a slider is slidably arranged on the electric slide rail, a connecting rod is fixed between adjacent sliders, a connecting seat is installed on one side of the connecting rod, and one end of the connecting seat is installed on the outer wall of the conveying mechanism.

[0010] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake silt of the present invention, the conveying mechanism includes a conveying cylinder installed inside the connecting seat, a conveying component is provided inside the conveying cylinder, and the sludge removal mechanism is installed at the bottom end of the conveying cylinder.

[0011] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake silt of the present invention, the silt-collecting mechanism includes a clamping cover, the cross-section of which is larger than the cross-section of the conveying cylinder, and two low-speed cutting components are respectively arranged on both sides of the clamping cover near the conveying cylinder, and the conveying components extend into the interior of the clamping cover.

[0012] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake silt of the present invention, the conveying component includes a housing first disposed above the conveying cylinder, a motor first disposed inside the housing first, a transmission shaft first disposed at the output end of the motor first, and a spiral feeding disc disposed on the outer wall of the transmission shaft first.

[0013] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake silt of the present invention, the low-speed cutting component includes a housing two disposed on the surface of the cover, a motor two installed inside the housing two, a transmission shaft two installed at one end of the output shaft of the motor two, and a spiral cutting blade disposed on the outer wall of the transmission shaft two.

[0014] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake siltation of the present invention, the two sets of spiral cutting blades have opposite spiral directions, which are used to gather the silt on both sides of the cover towards the middle and push it to the lower end of the conveying cylinder.

[0015] As a preferred embodiment of the environmentally friendly dredging construction device for river and lake silt of the present invention, the negative pressure suction mechanism includes a silt box, an air pump and a telescopic pipe. The silt box is installed on the outer shell of the electric cylinder, the air pump is installed on the surface of the silt box, and the two ends of the telescopic pipe are respectively connected to the air pump and the conveying cylinder.

[0016] The beneficial effects of the environmentally friendly dredging construction device for river and lake silt of the present invention are as follows: By setting up a semi-enclosed mud-collecting mechanism in conjunction with a low-speed cutting component, the mud-collecting mechanism's cover is positioned above the silt layer at the bottom of the river or lake during operation, isolating the cutting and crushing area from the external water body. This effectively inhibits the diffusion of silt particles into the surrounding water body and avoids the problem of large-scale turbidity caused by the agitation of traditional high-speed mixing blades. At the same time, the low-speed cutting component operates at a lower speed, which reduces the disturbance to the original soil below the silt layer during the cutting process and significantly reduces mechanical operating noise. This allows the device to maintain good operational adaptability in dredging conditions that are sensitive to noise and turbidity, such as shallow rivers, water depths of less than 3 meters, and urban landscape lakes.

[0017] The cross-section of the clamp is larger than that of the conveyor cylinder, and two low-speed cutting components are respectively set on both sides of the clamp near the conveyor cylinder. The spiral directions of the two spiral cutting blades are opposite. During operation, they can gather the sludge on both sides of the clamp towards the middle and push it to the lower end of the conveyor cylinder, which significantly improves the sludge collection efficiency and suction fullness, and avoids the problems of missed collection and repeated cutting caused by the traditional single-sided cutting method.

[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] The terminology used in this invention is that which is currently widely used in the art in view of the function of the invention. However, these terms may vary according to the intentions of those skilled in the art, precedents or new technologies in the art. In addition, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in the specification should not be construed as simple names, but rather as based on the meaning of the terms and the overall description of the invention.

[0026] Reference Figures 1 to 5 This embodiment provides an environmentally friendly dredging construction device for rivers and lakes, including: A base 1 is provided, and a rotation adjustment mechanism 2 is provided on the base 1. A gantry frame 4 is provided at one end of the rotation adjustment mechanism 2. A conveying mechanism 5 is vertically and movably installed on the gantry frame 4, and a mud-removing mechanism 6 is installed at the bottom of the conveying mechanism 5; The rotation adjustment mechanism 2 is equipped with a negative pressure suction mechanism 3, which is connected to the conveying mechanism 5; The mud-collecting mechanism 6 is semi-enclosed and contains a low-speed cutting component.

[0027] When the device is in operation, it is first positioned on a suspended platform in the river and lake dredging area or on a boat via the base 1. The base 1 provides a stable support foundation for each functional unit.

[0028] The rotation adjustment mechanism 2 is started, which drives the gantry frame 4 to adjust its angle in the horizontal direction and extend it outward, so that the vertically movable conveying mechanism 5 on the gantry frame 4 is aligned with the silt layer to be dredged. At the same time, the conveying mechanism 5 can be vertically raised and lowered along the gantry frame 4 to adapt to different water depths and riverbed topography.

[0029] When the mud-collecting mechanism 6 at the bottom of the conveying mechanism 5 descends to contact the silt layer at the bottom of the river or lake, the semi-enclosed cover of the mud-collecting mechanism 6 covers the silt layer, isolating the cutting and crushing area from the external water body. Then, the low-speed cutting component of the mud-collecting mechanism 6 operates at a low speed to cut and crush the silt layer at a low speed, effectively suppressing the diffusion of silt particles into the surrounding water body, and at the same time greatly reducing the operating noise.

[0030] While the cutting is in progress, the negative pressure suction mechanism 3 on the rotating adjustment mechanism 2 is activated. The negative pressure suction mechanism 3 is connected to the conveying mechanism 5, and a negative pressure suction force is formed inside the conveying mechanism 5. The sludge cut and crushed by the mud-collecting mechanism 6 is sucked into the conveying mechanism 5 under the action of the negative pressure suction force, and is then lifted and transported upward by the conveying mechanism 5. Finally, it is collected and stored by the negative pressure suction mechanism 3, thus completing the dredging operation.

[0031] Throughout the operation, the rotating adjustment mechanism 2 can adjust the working posture of the conveying mechanism 5 and the mud-taking mechanism 6 in real time, ensuring that the mud-taking mechanism 6 always contacts the silt layer in the best posture, so as to achieve continuous, efficient and environmentally friendly dredging construction.

[0032] Specifically, the rotation adjustment mechanism 2 includes a mounting bracket 201 installed on the side wall of the base 1. A motor 202 is installed at one end of the mounting bracket 201, and a turntable 203 is installed at one end of the motor 202. The turntable 203 is rotatably mounted on the base 1, and a pushing component is also provided at one end of the turntable 203.

[0033] Starting the motor 202 will drive the turntable 203 and the pushing component to rotate, which in turn drives the conveying mechanism 5 and the mud-collecting mechanism 6 to rotate.

[0034] Furthermore, the pushing component includes an electric cylinder 204 mounted on the side wall of the turntable 203, with a central fixing plate 205 mounted on one end of the electric cylinder 204, a gantry 4 mounted on the fixing plate 205, and a negative pressure suction mechanism 3 mounted on the outer shell of the electric cylinder 204.

[0035] The gantry 4 can be extended or retracted by the electric cylinder 204.

[0036] The gantry 4 has a strip groove, and an electric slide rail 401 is provided on the inner side of the strip groove. A slider 402 is slidably mounted on the electric slide rail 401. A connecting rod 403 is fixed between adjacent sliders 402. A connecting seat 404 is installed on one side of the connecting rod 403. One end of the connecting seat 404 is installed on the outer wall of the conveying mechanism 5.

[0037] Activating the electric slide rail 401 causes the slider 402 to move the conveying mechanism 5 downward, thereby facilitating the mud-collecting mechanism 6 to extend into the bottom of the river channel.

[0038] It should be noted that the conveying mechanism 5 includes a conveying cylinder 501 installed inside the connecting seat 404, a conveying assembly is provided inside the conveying cylinder 501, and a mud-taking mechanism 6 is installed at the bottom end of the conveying cylinder 501.

[0039] Specifically, the mud-collecting mechanism 6 includes a cover 601, the cross-section of which is larger than the cross-section of the conveying cylinder 501, and two low-speed cutting components are respectively arranged on both sides of the cover 601 near the conveying cylinder 501, with the conveying components extending into the interior of the cover 601.

[0040] During operation, the two low-speed cutting components operate synchronously at low speed, respectively cutting and crushing the silt on both sides of the cover 601, and then gathering and pushing the cut silt towards the middle to the lower end of the conveyor cylinder 501.

[0041] The conveying component inside the conveying cylinder 501 extends into the interior of the clamp 601, that is, the lower end of the conveying component extends into the interior of the clamp 601 and is close to the mud intake port, so as to lift and convey the cut mud gathered at the lower port of the conveying cylinder 501 in a timely manner, and prevent the mud from accumulating inside the clamp 601.

[0042] Furthermore, the conveying assembly includes a housing 502 disposed above the conveying cylinder 501, a motor 502 disposed inside the housing 502, a drive shaft 503 disposed at the output end of the motor 502, and a spiral feeding disc 504 disposed on the outer wall of the drive shaft 503.

[0043] Starting motor one will drive the spiral feeder disc 504 to rotate, thereby feeding the sludge from the cover 601 into the conveying cylinder 501 and slowly conveying it upwards, thus facilitating the sludge to enter the interior of the negative pressure suction mechanism 3.

[0044] The low-speed cutting assembly includes a housing 602 disposed on the surface of the cover 601. A motor is installed inside the housing 602. A transmission shaft 603 is installed at one end of the output shaft of the motor. A spiral cutting blade 604 is disposed on the outer wall of the transmission shaft 603.

[0045] It should be noted that the two sets of spiral cutting blades 604 have opposite spiral directions, which are used to gather the sludge on both sides of the cover 601 towards the middle and push it to the lower port of the conveyor cylinder 501.

[0046] Start motor 2 to drive the spiral cutting blade 604 to rotate slowly, lift out the sludge and push it towards the center, thus facilitating the subsequent removal of the sludge.

[0047] The negative pressure suction mechanism 3 includes a sludge tank 301, an air pump 302, and a telescopic pipe 303. The sludge tank 301 is mounted on the outer shell of the electric cylinder 204, the air pump 302 is mounted on the surface of the sludge tank 301, and the two ends of the telescopic pipe 303 are connected to the air pump 302 and the conveying cylinder 501, respectively.

[0048] Start the air pump 302 to suck the sludge into the sludge tank 301 for subsequent centralized treatment.

[0049] When in use, the entire device is positioned in the river and lake dredging area. The turntable 203 is driven to rotate in the horizontal plane by the motor 202. At the same time, the electric cylinder 204 extends and drives the gantry 4 to adjust, so that the vertically movable conveying mechanism 5 on the gantry 4 is aligned with the silt layer to be dredged.

[0050] The electric slide rail 401 drives the slider 402 to rise and fall along the strip groove. The connecting rod 403 drives the connecting seat 404 and the conveying cylinder 501 fixed inside the connecting seat 404 to move in the vertical direction, thereby adjusting the working depth of the conveying mechanism 5 and the mud-taking mechanism 6 to adapt to different water depths and riverbed topography.

[0051] When the mud-collecting mechanism 6 at the bottom of the conveying mechanism 5 descends to contact the silt layer at the bottom of the river or lake, the semi-enclosed cover 601 of the mud-collecting mechanism 6 is placed above the silt layer, relatively isolating the cutting and crushing area from the external water body.

[0052] Motor 2 drives transmission shaft 2 603 to rotate at low speed, which drives the spiral cutting blade 604 on the outer wall of transmission shaft 2 603 to rotate synchronously, cutting and crushing the sludge layer on both sides of the cover 601 at low speed. At the same time as the cutting is in progress, the negative pressure suction mechanism 3 is started. The air pump 302 is connected to the conveying cylinder 501 through the sludge box 301 and the telescopic pipe 303, forming a negative pressure suction force inside the conveying cylinder 501.

[0053] The motor drives the transmission shaft 503 to rotate, which in turn drives the spiral feeding disc 504 on the outer wall of the transmission shaft 503 to rotate. The sludge collected at the lower end of the conveying cylinder 501 is lifted and conveyed upward along the conveying cylinder 501, and finally enters the sludge box 301 through the telescopic pipe 303 for collection and storage, thus completing the sludge removal operation.

[0054] It should be understood that during the development of any practical implementation, such as in any engineering or design project, numerous specific implementation decisions may be made. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without much experimentation.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
