Description

Technical Field

[0001] This invention relates to the field of sludge cleaning technology in river construction, and particularly to a sludge cleaning device and its usage method for river construction. Background Technology

[0002] In slow-flowing river channels, large amounts of sludge rich in organic matter tend to accumulate. Excessive sludge accumulation can lead to disasters such as riverbed rise, levee breaches, and even river course changes. However, the sludge in the river channel is rich in organic matter and can be used as natural fertilizer or for brick making. Therefore, the utilization of river sludge has multiple benefits, and sludge cleaning devices are now widely used to clean river channels.

[0003] There are many existing technologies for sludge cleaning devices. However, when using existing sludge cleaning devices, they usually use a sludge pump to clean the sludge by suction. However, during the cleaning process, the water in the river and the sludge are sucked out together, which reduces the water volume in the river and affects the river's ecological environment. Moreover, after the sludge is cleaned, it cannot be quickly dewatered and collected, resulting in low sludge collection efficiency.

[0004] For example, Chinese Patent Publication No. CN214194713U discloses a combined extraction device for river sludge treatment, relating to the field of extraction devices. It includes a sludge extraction device, a rotating device, a supporting device, a filtering device, and a water pumping device. The sludge extraction device includes a sludge pump and a hose. The rotating device includes a swing rod, a connecting plate, and rotating balls. One side of the sludge pump is welded to one end of the swing rod. The upper surface of the connecting plate has a first through hole. The supporting device includes a hull, a baffle, and a support column. The upper end of the support column is connected to the surface of the rotating balls, and the lower surface of the baffle is connected to the upper surface of the hull. The filtering device includes a sedimentation tank with a second through hole on one side. One end of the hose is installed in the second through hole. The water pumping device includes a water pump with its lower surface connected to the upper surface of the baffle. This invention allows the sludge pump to move up, down, left, and right underwater by manually manipulating the swing rod in the rotating device. However, it has the following drawbacks:

[0005] Cleaning efficiency and blind spots:

[0006] The lack of sufficient consideration for water separation in the sludge resulted in high water content in the collected sludge, increasing the difficulty of subsequent treatment. At the same time, the limited range of movement of the sludge suction pump underwater may create blind spots in the cleaning process, preventing comprehensive cleaning.

[0007] Ecological protection:

[0008] The process of cleaning up sludge may also drain water from the river, reducing the water volume in the river and affecting the river's ecological environment.

[0009] Level of automation:

[0010] Relying on manual manipulation of the swing arm in the rotating device to move the sludge pump reduces the level of automation and increases labor costs and operational complexity.

[0011] Sludge collection and sealing:

[0012] The lack of an effective sealing mechanism to ensure that the collected sludge does not leak during transportation or treatment could lead to sludge spillage and environmental pollution.

[0013] Secondary collection capability:

[0014] The lack of a secondary collection design may result in low sludge collection efficiency.

[0015] To address the above problems, this invention proposes a sludge cleaning device and its usage method for river construction. Summary of the Invention

[0016] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, the present invention provides a sludge cleaning device and a method for using it in river construction.

[0017] The technical solution is as follows: a sludge cleaning device for river construction includes a floating seat that floats on the river surface. A control cabin is located at the top of the floating seat to control its movement path. Collection boxes are located on the side walls of the floating seat. Power source components are located at both ends of the floating seat. Each power source component includes a moving control arm and a rotating control shaft. A support plate is rotatably mounted at the end of the rotating control shaft. Several collection tanks are located on the surface of the support plate. The collection tanks have a hollow interior and a stepped surface that is wider at the top and narrower at the bottom. When the moving control arm drives the rotating control shaft to move towards the sludge in the river, the collection tanks on the support plate press against the sludge at the bottom of the river, causing the sludge to be collected into the collection tanks. A groove is located near the bottom inner wall of each collection tank, and a sliding component is located within the groove. An adaptive sealing component is located at the bottom of the sliding component to seal the end of the collected tank after collection.

[0018] As a further improvement to this technical solution, the side wall of the collection tank is provided with several through holes, and the inner wall of the collection tank is provided with a filter layer. The filter layer is used to separate the water in the sludge. By rotating the control shaft, the support plate is rotated, causing the collection tank on the surface of the support plate to rotate. The sludge inside the collection tank undergoes centrifugal motion, and the water in the sludge is thrown out from the filter layer by centrifugal force and flows into the river through the filter layer.

[0019] As a further improvement to this technical solution, the sliding assembly includes a cylindrical column disposed on the inner wall of the sliding groove, a sliding column slidably disposed on the inner wall of the cylindrical column, a first elastic element disposed between the cylindrical column and the sliding column, and an adaptive sealing assembly disposed at the bottom of the sliding column.

[0020] As a further improvement to this technical solution, the adaptive sealing assembly includes an arc plate located at the bottom of the collection tank. The surface of the arc plate is bowl-shaped, and a T-shaped plate is provided at the bottom of the arc plate. Symmetrical support columns are provided on both sides of the inner wall of the T-shaped plate. An arc-shaped baffle is rotatably connected to the surface of the support column. The arc edge of the arc-shaped baffle fits against the inner wall of the arc plate. When the arc-shaped baffle rotates on the surface of the support column, it can only rotate vertically downwards.

[0021] As a further improvement to this technical solution, the surface of the support column is provided with a second elastic element, and the two ends of the second elastic element are respectively connected to a T-shaped plate and an arc-shaped baffle. In the natural state, the arc-shaped baffle is horizontal under the force of the second elastic element, and a sealed space is formed between the arc-shaped baffle and the inner wall of the arc plate.

[0022] As a further improvement to this technical solution, symmetrical limiting blocks are provided on both sides of the top of the arc plate. The top of the limiting blocks is fixedly connected to the bottom of the sliding column. In its natural state, the arc plate is sealed to the bottom of the collection tank by the force of the sliding component.

[0023] As a further improvement to this technical solution, a feeding component is provided on the top of the collection tank. The feeding component is used to squeeze the inside of the collection tank after collection is completed, so that the sludge inside the collection tank is discharged and collected.

[0024] As a further improvement to this technical solution, the feeding assembly includes a cylinder located at the top of the collection tank. The piston rod at the end of the cylinder passes through the top of the collection tank and has a squeezing plate at its end. The outer wall of the squeezing plate is attached to the inner wall of the collection tank. By pushing the cylinder, the squeezing plate is moved to squeeze the sludge inside the collection tank, so that the sludge is automatically fed through the squeezing adaptive sealing assembly to open the arc-shaped baffle.

[0025] The method of using a road surface cleaning device for road construction includes the following steps:

[0026] S1. The floating seat is controlled by the control cabin to move the power source assembly along the planned path. The rotating control axis is inserted into the river channel by the moving control arm. The support plate at the end of the rotating control axis and the collection tank on the surface of the support plate are inserted and collected by the moving control arm to collect the sludge at the bottom of the river channel.

[0027] S2. By opening through holes in the outer wall of the collection tank, when the moving control arm drives the rotating control shaft to move into the river channel, the support plate at the end of the rotating control shaft drives the collection tank to be inserted into the sludge in the river channel. The sludge in the river channel is collected inside the collection tank under the pressure of compression. When the collection is completed, the bottom of the collection tank is automatically sealed by the adaptive sealing component. The rotating control shaft drives the support plate to rotate coaxially. Since there are through holes on the surface of the collection tank, when the sludge in the collection tank rotates, the water in the sludge is subjected to centrifugal force. The density of the water is less than that of the sludge, so the water is thrown out from the chute and flows out into the river channel through the through holes. This avoids the water being carried out during the sludge cleaning process, thus protecting the river channel ecology. After the water is thrown out, some storage space is released inside the collection tank. By inserting the collection tank into the sludge in the river channel again, the sludge is collected a second time. The rotating control shaft drives the support plate to rotate coaxially, so that the collection tank rotates coaxially to perform centrifugal dewatering.

[0028] S3. The control arm moves the control shaft to the top of the collection box. The piston rod at the end of the cylinder pushes the squeezing plate. Since the squeezing plate is in contact with the inner wall of the collection tank, the squeezing plate pushes the sludge inside the collection tank during the movement. After being squeezed, the sludge is squeezed against the arc-shaped baffle. The arc-shaped baffle rotates on the surface of the support column, so that the arc-shaped baffle and the bottom of the arc plate form an opening, so that the dewatered sludge falls into the collection box, which facilitates the collection of dewatered sludge.

[0029] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows:

[0030] In this sludge cleaning device for river construction, a control shaft drives a support plate to rotate coaxially. Because the collection tank has through holes, when the sludge inside rotates, the water in the sludge is subjected to centrifugal force. Since the water density is less than the sludge density, the water is thrown out from the chute and flows into the river through the through holes. This prevents water from being carried out during sludge cleaning, thus protecting the river's ecosystem. After the water is thrown out, some storage space is released inside the collection tank. The collection tank is then inserted back into the river sludge area for secondary collection. The control shaft drives the support plate to rotate coaxially, causing the collection tank on the support plate to rotate coaxially for centrifugal dewatering, allowing the water to flow into the river and preventing water loss, thus protecting the river's healthy ecosystem.

[0031] In this sludge cleaning device for river construction, when the collection tank is inserted into the sludge, the sludge squeezes the bottom of the adaptive sealing component due to the interaction force. Because the T-shaped plate limits the top of the arc-shaped baffle, the arc-shaped baffle pushes the limiting block upward when it is subjected to the squeezing force. During the upward movement of the arc plate, an opening is formed with the bottom of the collection tank, allowing the sludge to enter the collection tank from the opening for collection. After collection is completed, the squeezing of the sludge stops. After the external force on the adaptive sealing component disappears, the sliding component pushes the limiting block in the opposite direction, causing the limiting block to drive the arc plate to seal the opening at the bottom of the collection tank, preventing the sludge from falling out during the collection process, thereby improving the sludge collection efficiency.

[0051] Example 1

[0052] like Figures 1-9As shown, a sludge cleaning device for river construction includes a floating seat 100 that floats on the river surface. A control cabin 101 is located at the top of the floating seat 100, controlling its movement path. Collection boxes 102 are located on the side walls of the floating seat 100. Power source assemblies 200 are located at both ends of the floating seat 100. Each power source assembly 200 includes a moving control arm 201 and a rotating control shaft 202. A support plate 300 is rotatably mounted at the end of the rotating control shaft 202. Several collection tanks 400 are located on the surface of the support plate 300. The interior is hollow, and the surface of the collection tank 400 is stepped, wider at the top and narrower at the bottom. When the moving control arm 201 drives the rotation control shaft 202 to move towards the river sludge, the collection tank 400 on the surface of the support plate 300 presses the sludge at the bottom of the river. The sludge is collected into the collection tank 400 under pressure. The inner wall of the collection tank 400 near the bottom is provided with a sliding groove 401. A sliding component 404 is provided in the sliding groove 401. An adaptive sealing component 500 is provided at the bottom of the sliding component 404. The adaptive sealing component 500 is used to seal the end of the collection tank 400 after collection.

[0053] Considering that the collection and cleaning of sludge may easily carry away water from the river, resulting in a significant reduction in water volume and affecting the river's ecology, the collection tank 400 has several through holes 403 on its side wall, and a filter layer 402 is provided on the inner wall of the collection tank 400. The filter layer 402 is used to separate water from the sludge. By rotating the control shaft 202, the support plate 300 is driven to rotate, causing the collection tank 400 on the surface of the support plate 300 to rotate. The sludge inside the collection tank 400 undergoes centrifugal motion, and the water in the sludge is thrown out from the filter layer 402 by centrifugal force and flows into the river through the filter layer 402.

[0054] Considering that when the collection tank 400 finishes collecting sludge, during the centrifugal discharge of the sludge-water mixture inside the collection tank 400, sludge is prone to flow out from the bottom of the collection tank 400. To improve the sealing performance of the collection tank 400, the sliding assembly 404 includes a column 4041 disposed on the inner wall of the slide groove 401. A sliding column 4043 is slidably disposed on the inner wall of the column 4041. A first elastic element 4042 is disposed between the column 4041 and the sliding column 4043. An adaptive sealing assembly 500 is disposed at the bottom of the sliding column 4043. The sliding column 4043 slides on the inner wall of the column 4041. In its natural state, the sliding column 4043 is squeezed by the force of the first elastic element 4042, so that the adaptive sealing assembly 500 disposed at the bottom of the first elastic element 4042 seals the bottom of the collection tank 400, thereby preventing sludge leakage during the centrifugal drainage of the collection tank 400 and improving the sealing performance of the collection tank 400.

[0055] When collecting sludge from the collection tank 400, to prevent the adaptive sealing assembly 500 from blocking the collection port and affecting the sludge collection efficiency, the adaptive sealing assembly 500 includes an arc-shaped plate 501 at the bottom of the collection tank 400. The surface of the arc-shaped plate 501 is bowl-shaped, and a T-shaped plate 502 is provided at the bottom of the arc-shaped plate 501. Symmetrical support columns 503 are provided on both sides of the inner wall of the T-shaped plate 502. An arc-shaped baffle 504 is rotatably connected to the surface of the support column 503. The arc edge of the arc-shaped baffle 504 fits against the inner wall of the arc-shaped plate 501. When the arc-shaped baffle 504 rotates on the surface of the support column 503, it can only rotate vertically downwards. Symmetrical limiting blocks 506 are provided on both sides of the top of the arc-shaped plate 501. The top of the limiting blocks 506 is fixedly connected to the bottom of the sliding column 4043. In its natural state, the arc-shaped plate 501 is subject to the sliding assembly. The force of component 404 seals the bottom of the collection tank 400. When the collection tank 400 is inserted into the sludge, the sludge squeezes the bottom of the adaptive sealing component 500 due to the interaction force. Since the T-shaped plate 502 limits the top of the arc-shaped baffle 504, the arc-shaped baffle 504 pushes the limiting block 506 upward when it is subjected to the squeezing force. During the upward movement of the arc plate 501, an opening is formed with the bottom of the collection tank 400, allowing the sludge to enter the collection tank 400 for collection. After collection is completed, the squeezing of the sludge stops. After the external force on the adaptive sealing component 500 disappears, the force of the sliding component 404 pushes the limiting block 506 in the opposite direction, causing the limiting block 506 to drive the arc plate 501 to seal the opening at the bottom of the collection tank 400, thereby improving the sludge collection efficiency.

[0056] Considering that during the sealing process of the bottom of the arc plate 501, the arc baffle 504 rotates on the surface of the support column 503 due to the weight of the sludge, causing an opening between the arc baffle 504 and the arc plate 501, resulting in sludge falling out of the collection tank 400 and affecting the sludge collection efficiency, the support column 503 is provided with a second elastic element 505. The two ends of the second elastic element 505 are respectively connected to the T-shaped plate 502 and the arc baffle 504. In its natural state, the arc baffle 504 is horizontal under the force of the second elastic element 505, and a sealed space is formed between the arc baffle 504 and the inner wall of the arc plate 501. The second elastic element 505 limits the arc baffle 504, thereby preventing sludge from leaking out from the bottom of the arc baffle 504 and improving the sludge collection efficiency.

[0057] To facilitate the collection of dewatered sludge inside the collection tank 400 and improve cleaning efficiency after sludge collection is completed, a feeding assembly 600 is provided at the top of the collection tank 400. The feeding assembly 600 is used to squeeze the inside of the collection tank 400 after collection, so that the sludge inside the collection tank 400 is discharged and collected. The feeding assembly 600 includes a cylinder 601 located at the top of the collection tank 400. The piston rod at the end of the cylinder 601 passes through the top of the collection tank 400 and has a squeezing plate 602 at the end. The outer wall of the squeezing plate 602 is attached to the inner wall of the collection tank 400. By pushing the cylinder 601, the squeezing plate 602 is moved to squeeze the sludge inside the collection tank 400, so that the sludge is automatically discharged through the squeezing adaptive sealing assembly 500, which opens the arc-shaped baffle 504.

[0058] In summary, the working principle of this invention is as follows: The control cabin 101 controls the floating seat 100 to drive the power source assembly 200 to move along a predetermined path. The moving control arm 201 drives the rotating control shaft 202 to insert into the river channel. The end of the rotating control shaft 202 is provided with a support plate 300. The collection tank 400 provided on the surface of the support plate 300 is inserted into and collected from the bottom of the river channel under the control of the moving control arm 201. When the collection tank 400 is inserted into the sludge, due to the interaction force, the sludge squeezes the bottom of the adaptive sealing assembly 500. Since the T-shaped plate 502 limits the top of the arc-shaped baffle 504, the arc-shaped baffle 504 is pushed upward by the squeezing force, causing the arc-shaped baffle 504 to move upward. During the upward movement of the arc plate 501, an opening is formed with the bottom of the collection tank 400, allowing the sludge to enter the collection tank 400 from the opening. The sludge in the river is collected by compression inside the collection tank 400. After collection, the compression of the sludge stops. After the external force on the adaptive sealing component 500 disappears, the sliding component 404 pushes the limiting block 506 in the opposite direction, causing the limiting block 506 to drive the arc plate 501 to seal the bottom opening of the collection tank 400, preventing the sludge from falling out of the opening. The rotation control shaft 202 drives the support plate 300 to rotate coaxially. Since the surface of the collection tank 400 has through holes 403, when the sludge in the collection tank 400 rotates, the water in the sludge is subjected to centrifugal force. The density of the water is less than that of the sludge, so the water is thrown out from the chute 401 and flows out of the through holes 403 into the river, preventing the water from being carried out during the sludge cleaning process, thus protecting the river ecology.

[0059] A method for using a road surface cleaning device for road construction includes the following steps:

[0060] S1. The control cabin 101 controls the floating seat 100 to drive the power source assembly 200 to move along the planned path. The moving control arm 201 drives the rotation control shaft 202 to insert into the river channel. The support plate 300 at the end of the rotation control shaft 202 and the collection tank 400 on the surface of the support plate 300 are inserted and collected by the moving control arm 201 to collect the sludge at the bottom of the river channel.

[0061] S2. By opening a through hole 403 on the outer wall of the collection tank 400, when the moving control arm 201 drives the rotation control shaft 202 to move into the river channel, the support plate 300 at the end of the rotation control shaft 202 drives the collection tank 400 to insert into the sludge in the river channel. The sludge in the river channel is collected inside the collection tank 400 under pressure. When the collection is completed, the bottom of the collection tank 400 is automatically sealed by the adaptive sealing component 500. The support plate 300 is driven to rotate coaxially by the rotation control shaft 202. Since the surface of the collection tank 400 has a through hole 403, when the sludge in the collection tank 400 rotates... During the process, the water in the sludge is subjected to centrifugal force. Since the density of the water is less than that of the sludge, the water is thrown out from the chute 401 and flows out into the river through the through hole 403. This avoids carrying water out during the sludge cleaning process, thus protecting the river's ecology. After the water is thrown out, some storage space is released inside the collection tank 400. By inserting the collection tank 400 back into the sludge in the river, the sludge is collected a second time. The control shaft 202 drives the support plate 300 to rotate coaxially, which in turn causes the collection tank 400 to rotate coaxially for centrifugal dewatering, improving the efficiency of sludge collection.

[0062] S3. The control arm 201 drives the rotation control shaft 202 to move above the collection box 102. The piston rod at the end of the cylinder 601 pushes the extrusion plate 602. Since the extrusion plate 602 is in contact with the inner wall of the collection tank 400, the extrusion plate 602 pushes the sludge inside the collection tank 400 during the movement. After being subjected to the extrusion force, the sludge is squeezed against the arc-shaped baffle 504. The arc-shaped baffle 504 rotates on the surface of the support column 503, so that the arc-shaped baffle 504 and the bottom of the arc plate 501 form an opening, so that the dewatered sludge falls into the collection box 102, which facilitates the collection of dewatered sludge and improves the cleaning efficiency.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

9. A method for using a road cleaning device for road construction according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1. The floating seat (100) is controlled by the control cabin (101) to drive the power source assembly (200) to move along a planned path, and the rotating control shaft (202) is driven to be inserted into the river channel by the moving control arm (201). The support plate (300) provided at the end of the rotating control shaft (202) and the collection tank (400) provided on the surface of the support plate (300) are inserted to collect the sludge at the bottom of the river channel under the control of the moving control arm (201); S2. By opening a through hole (403) on the outer wall of the collection tank (400), when the movable control arm (201) drives the rotating control shaft (202) to move into the river channel, the support plate (300) provided at the end of the rotating control shaft (202) drives the collection tank (400) to be inserted into the sludge in the river channel. The sludge in the river channel is squeezed and collected inside the collection tank (400). When the collection is completed, the bottom of the collection tank (400) is automatically sealed by the adaptive sealing component (500). The rotating control shaft (202) drives the support plate (300) to rotate coaxially. Since the through hole (403) is opened on the surface of the collection tank (400), when During the rotation of the sludge in the collecting tank (400), the water in the sludge is subjected to the centrifugal force, and the water density is less than the sludge density, so that the water is thrown out from the chute (401), and the water flows out from the through hole (403) into the river channel, thereby avoiding the water being brought out during the sludge cleaning process, thereby protecting the river channel ecology. After the water is thrown out, part of the storage space inside the collecting tank (400) is released, and the collecting tank (400) is inserted into the river channel sludge again to collect the sludge for a second time, and the support plate (300) is driven to rotate coaxially by rotating the control shaft (202), so that the collecting tank (400) rotates coaxially to perform centrifugal water removal; S3. The control arm (201) is moved to drive the rotating control shaft (202) to move to the top of the collection box (102). The piston rod at the end of the cylinder (601) pushes the squeezing plate (602). Since the squeezing plate (602) is in contact with the inner wall of the collection tank (400), the squeezing plate (602) pushes the sludge inside the collection tank (400) during the movement. After being subjected to the squeezing force, the sludge squeezes the arc baffle (504). The arc baffle (504) rotates on the surface of the support column (503), so that an opening is formed between the arc baffle (504) and the bottom of the arc plate (501), so that the dehydrated sludge falls into the collection box (102), thereby facilitating the collection of the dehydrated sludge.
