Description

Technical Field

[0001] The invention relates to the technical field of river channel silt clearing, and more specifically, to a river channel silt clearing device. Background Art

[0002] River silt refers to unconsolidated soft fine or very fine soil that is deposited in a still or slow-flowing water environment and formed by physical, chemical and biochemical processes. It is a modern recent sediment. The accumulation of river silt will affect the normal functioning of flood control, drainage, irrigation, water supply, navigation and other functions. In order to restore the normal function of the river, it is necessary to clean up the river silt. In the curved part of the river, the water flow is relatively slow. Therefore, the particles and suspended matter contained in the river water flow are very easy to be deposited in the curved part of the river, causing the riverbed height in the curved part of the river to rise, thereby reducing the drainage and flood discharge in the curved part of the river.

[0003] In the invention patent with patent publication number: CN112982527A, a river silt cleaning device is disclosed, which includes: a mounting plate, a retention box is arranged at the bottom of the mounting plate, the retention box is a box body with an opening downward, the retention box is vertically slidably connected to the mounting plate, a mud discharge pipe is connected to the retention box, a sludge pump is fixedly connected to the mounting plate, the sludge pump is connected to the mud discharge pipe, a corrugated pipe is connected between the sludge pump and the mud discharge pipe, and a stirring component for stirring the sludge is arranged in the retention box.

[0004] Although this type of river channel silt cleaning device has the effect of improving dredging efficiency, this type of river channel silt cleaning device is achieved by covering the bottom of the river channel with an interception box, stirring the silt under the interception box, and then pumping it out with a sludge pump. When the interception box is downwardly covered on the silt at the bottom of the river channel, aquatic organisms such as fish and shrimp that have not escaped from the bottom of the river channel in time, as well as some organisms existing in the river channel silt, will also be retained in the retention box. In the process of stirring the silt, the life safety of the aquatic organisms retained in the retention box will also be threatened, thereby affecting the life safety of some aquatic organisms.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. In the present invention, the salvage box is pushed toward the arc-shaped plate by the flow of river water. In the process of the salvage box driving the salvage teeth to move, the salvage teeth scrape up the silt, and the salvage box scrapes the silt into the salvage box, while the arc-shaped plate blocks the scraped silt, so that in the process of the first chain driving the salvage box to move upward, the salvage box scrapes the silt into the salvage box. At the same time, in the process of the first chain driving the salvage box to move upward, when the salvage teeth pass through the pollution blocking plate, the salvage teeth salvage the pollutants intercepted by the pollution blocking plate, such as leaves floating on the water surface. As the salvage box moves upward, the pollutants salvaged by the salvage teeth slide into the salvage box through the inclined surface of the salvage teeth.

[0032] 2. In the present invention, the sludge treatment plate is heated by a heater, and the sludge treatment plate transfers heat to the sludge, thereby promoting the evaporation of water in the sludge, making the sludge semi-solidified. During the rotation of the rotating shaft, one of the rotating shafts drives the driving shaft to rotate through the cooperation of the second sprocket and the second chain, and drives the sludge pushing plate to rotate, so that the semi-solidified sludge is pushed into the discharge tube through the sludge pushing plate, and then discharged to the outer bank of the river bend, thereby reinforcing the height of the river bank.

[0033] 3. In the present invention, the bottom of the salvage box at the bottom of the first chain provides resistance to the flow of river water, so that the river water pushes the salvage box to one side during the flow, thereby driving the first chain to rotate. The salvage box at the bottom of the first chain salvages the silt at the bottom of the river channel during the movement, thereby achieving the cleaning of the silt at the bottom of the river channel. At the same time, the resistance of the salvage box at the bottom of the first chain to the flow of river water reduces the flow velocity of the river water, thereby reducing the impact force of the river water flow on the river bank at the curved part of the river channel, thereby reducing the erosion of the river bank outside the curved part of the river channel.

[0034] 4. In the present invention, the connecting plate is supported by the support rod, so that a certain gap is formed between the lower end surface of the connecting plate and the trash retaining plate and the upper end surface of the first baffle plate, so that aquatic organisms such as fish and shrimp can swim downstream through the gap between the trash retaining plate and the first baffle plate, thereby ensuring the life safety of the organisms in the water in the river.

[0047] A sludge treatment plate 4 is provided with a heater 5, and a sludge pushing plate 6 is rotatably connected to the sludge treatment plate 4. The rotating unit cooperates with the sludge pushing plate 6, and the rotating unit is used to drive the sludge pushing plate 6 to rotate, so that the sludge pushing plate 6 pushes the sludge on the sludge treatment plate 4 to the end of the sludge treatment plate 4, and the end of the sludge treatment plate 4 is fixedly connected with a discharge cylinder 43, and the discharge cylinder 43 is fixedly connected to the side wall of the support plate 2 in an inclined manner, and the lower end of the discharge cylinder 43 passes through the side wall of the support plate 2 and extends to one side of the support plate 2, and the discharge cylinder 43 facilitates the discharge of the sludge on the sludge treatment plate 4 to the river bank.

[0048] The power storage mechanism includes an outer box body 7, a speed increaser 8 is fixedly connected to the inner wall of the outer box body 7, one end of the speed increaser 8 is matched with the rotating unit, a generator 9 is fixedly connected to the output shaft of the speed increaser 8, the generator 9 is fixedly connected to the inner wall of the outer box body 7, the wires on the generator 9 are electrically connected to the battery 10, the battery 10 is fixedly connected to the bottom of the outer box body 7, and the wires on the heater 5 are electrically connected to the battery 10. During the rotation of the rotating unit, the speed increaser 8 is driven, and the output shaft on the speed increaser 8 drives the rotating shaft on the generator 9 to rotate, so that the generator 9 generates electricity, and the generator 9 transmits the electricity to the battery 10 and stores it, so as to facilitate the battery 10 to transmit electricity to the heater 5.

[0049] The pollution blocking plate 11 is slidably connected to the side wall of the support plate 2, and the pollution blocking plate 11 cooperates with the salvage box 3. The lower half of the pollution blocking plate 11 is located in the river water, and the upper half of the pollution blocking plate 11 is located on the upper side of the river water surface, so as to intercept pollutants such as leaves and aquatic plants suspended on the surface of the river water and below the surface of the river water.

[0050] The cleaning brush 12 is rotatably connected to the support plate 2 and is located on the upper side of the salvage mechanism. The cleaning brush 12 cooperates with the salvage box 3. The rotation direction of the cleaning brush 12 is opposite to the rotation direction of the rotating unit, so that the cleaning brush 12 can clean the attachments on the surface of the salvage box 3.

[0051] A vertically arranged first baffle 13 is fixedly connected to the upper surface of the fixing frame 1, and an arc-shaped plate 14 is fixedly connected to the lower end of the first baffle 13, and the arc-shaped plate 14 cooperates with the salvage box 3. A support rod 15 is fixedly connected to the upper surface of the first baffle 13, and the support rod 15 cooperates with the trash-blocking plate 11. The end of the first baffle 13 is fixedly connected to the side wall of the support plate 2. The first baffle 13 can not only block the water flow and reduce the flow speed of the water near the fixing frame 1, but also block the silt when the salvage box 3 salvages the silt at the bottom of the river channel, thereby preventing the silt at the bottom of the river channel from flowing downstream.

[0052] The rotating unit includes a rotating shaft 16, and there are multiple rotating shafts 16. Both ends of the rotating shaft 16 are rotatably connected to the side walls of the support plate 2, and the rotating shaft 16 is close to the four corners of the support plate 2. There are two groups of rotating shafts 16, and the two groups of rotating shafts 16 are distributed up and down, and each group has two horizontally arranged rotating shafts 16. The two groups of rotating shafts 16 are connected to form a rectangle. The sludge processing plate 4 is located between the two groups of rotating shafts 16 and close to the rotating shaft 16 located on the upper side. When the salvage box 3 moves to the top of the upper rotating shaft 16, at this time, the open end of the salvage box 3 is located on the side of the salvage box 3, and the sludge salvaged in the salvage box 3 flows downward through the opening on the side of the salvage box 3 to the sludge processing plate 4, thereby realizing the collection and processing of the salvaged sludge.

[0053] The first sprocket 17 is fixedly connected to the two ends of the rotating shaft 16. The first sprocket 17 is sleeved with a first chain 18. The first chain 18 is fixedly connected to a plurality of connecting blocks 19. The ends of the salvage box 3 are fixedly connected to the connecting blocks 19. The salvage box 3 is located below the rotating shaft 16 and close to the lower end of the support plate 2. Its opening direction is consistent with the flow direction of water in the river channel. Therefore, when the salvage box 3 is located below the first chain 18, the side wall of the salvage box 3 is opposite to the flow direction of water. Therefore, in the water During the flow, water pushes the salvage box 3 toward the arc-shaped plate 14. During the movement of the salvage box 3, since the opening of the salvage box 3 is on the side, the bottom of the salvage box 3 salvages the silt at the bottom of the river channel through the opening end. As the water flow continuously pushes the salvage box 3, the first chain 18 is driven to rotate. The first chain 18 is engaged with the first sprocket 17, which drives the first sprocket 17 and the rotating shaft 16 to rotate, thereby realizing the upward transportation of the silt salvaged by the salvage box 3 to the silt treatment plate 4.

[0054] When the opening of the salvage box 3 is placed upward, the width of the salvage box 3 is greater than the height. When the salvage box 3 moves to the lower side of the first chain 18, the bottom of the salvage box 3 is located on one side, thereby increasing the contact area between the bottom of the salvage box 3 and the water flow, making it easier for the water flow to push the salvage box 3 to one side.

[0055] A salvage tooth 20 is fixedly connected to the side wall of the salvage box 3, and the salvage tooth 20 is arranged opposite to the first chain 18. The salvage tooth 20 can not only be inserted into the silt, but also reduce the resistance between the side wall of the port end of the salvage box 3 and the silt, so as to facilitate the salvage box 3 to salvage the silt at the bottom of the river channel. At the same time, when the first chain 18 drives the salvage box 3 to move upward, when the salvage box 3 and the salvage tooth 20 move upward through the pollution blocking plate 11, the salvage tooth 20 can salvage pollutants such as leaves, floating water plants, etc. intercepted by the pollution blocking plate 11, thereby facilitating the cleaning of pollutants floating in the river channel.

[0056] A discharge port 21 is provided on one side of the salvage box 3 adjacent to the open end. The discharge port 21 is close to the first chain 18 and is arranged opposite to the first chain 18. A cover plate 22 is slidably connected to the side wall of the discharge port 21. A limiting mechanism is provided on the side wall of the support plate 2, and the limiting mechanism cooperates with the cover plate 22.

[0057] A fixing block 23 is fixedly connected to the lower surface of the cover plate 22, and a limiting rod 24 is fixedly connected to the side wall of the fixing block 23. One end of the limiting rod 24 passes through the side wall of the connecting block 19 and is fixedly connected to the limiting block 25. A first spring 26 is fixedly connected to the limiting block 25, and one end of the first spring 26 is fixedly connected to the side wall of the connecting block 19. The limiting block 25 cooperates with the limiting mechanism, and a circular through hole is provided on the connecting block 19. The end of the limiting rod 24 passes through the circular through hole and is connected to the limiting block 25. During the movement of the cover plate 22, the limiting rod 24 can prevent the position of the cover plate 22 from shifting to the side, and the elastic force of the first spring 26 can facilitate the restoration of the position of the cover plate 22.

[0058] The limiting mechanism includes a baffle rod 27, a limiting cavity 28 is provided on the inner wall of the support plate 2, a sliding plate 29 is elastically connected to the bottom of the limiting cavity 28, the baffle rod 27 is horizontally fixedly connected to the side wall of the sliding plate 29, and one end of the baffle rod 27 extends to the outside of the support plate 2 and is arranged opposite to the limiting block 25.

[0059] The push block 30 is fixedly connected to the side wall of the sliding plate 29, and the push block 30 is located below the stop rod 27. The push block 30 cooperates with the connecting block 19. The push block 30 is located at an end face of the outer side of the limit cavity 28 and is inclined. The inclined surface on the push block 30 is arranged opposite to the connecting block 19, and the push block 30 is located at the lower side of the limit block 25. When the first chain 18 drives the salvage box 3 loaded with silt to move to the upper side of the rotating shaft 16, the open end of the salvage box 3 is located at the side. When the stop rod 27 contacts the limit block 25, the first chain 18 drives the salvage box 3 loaded with silt to move to the upper side of the rotating shaft 16. At this time, the opening end of the salvage box 3 is located at the side. The box 3 continues to move, and the blocking rod 27 prevents the limit block 25, the fixed block 23 and the cover plate 22 from moving with the salvage box 3. Therefore, during the movement of the salvage box 3, the cover plate 22 is blocked by the blocking rod 27, so that the cover plate 22 moves to one side of the salvage box 3. At this time, the discharge port 21 is in an open state, and the sludge salvaged in the salvage box 3 flows downward from the discharge port 21 to the sludge processing plate 4. At the same time, during the process of the cover plate 22 moving in the opposite direction to the open end of the salvage box 3, the side of the salvage box 3 pushes the sludge on the cover plate 22 to one side, thereby facilitating the sludge in the salvage box 3 to flow out.

[0060] The second spring 31, one end of the second spring 31 is fixedly connected to the side wall of the limiting cavity 28, and the other end of the second spring 31 is fixedly connected to the side wall of the sliding plate 29. Through the elastic force of the second spring 31, the second spring 31 pushes the sliding plate 29 in the direction of the push block 30, thereby facilitating the pushing block 30 and the blocking rod 27 to be pushed out of the limiting cavity 28.

[0061] The longitudinal section of the sludge treatment plate 4 is arc-shaped, and a drying chamber 32 is opened in the sludge treatment plate 4. The heater 5 is fixedly connected to the top of the drying chamber 32. The sludge treatment plate 4 is made of a heat-conducting material. The heater 5 heats the sludge treatment plate 4 so that the sludge treatment plate 4 transfers heat to the sludge, thereby promoting the evaporation of water in the sludge, reducing the water content in the sludge, making the sludge semi-solidified, reducing the fluidity of the sludge, and facilitating the accumulation of sludge on the river bank, thereby increasing the height of the river bank.

[0062] The sludge pushing plate 6 is a spiral stripping plate, and the circumferential wall of the sludge pushing plate 6 is in contact with the inner arc wall of the sludge treatment plate 4, and a driving shaft 33 is fixedly connected to the sludge pushing plate 6, and the end of the driving shaft 33 is rotatably connected to the side wall of the support plate 2, and one end of the driving shaft 33 passes through the side wall of the support plate 2 and the outer box body 7 and extends into the outer box body 7.

[0063] The end of the rotating shaft 16 located at the upper end of the support plate 2 passes through the side walls of the support plate 2 and the outer box body 7 and is fixedly extended into the outer box body 7. A second sprocket 34 is arranged in the outer box body 7. The second sprocket 34 is respectively fixedly connected to one of the rotating shafts 16 and the end of the driving shaft 33. A second chain 35 is sleeved on the second sprocket 34. In the process of the first chain 18 driving the first sprocket 17 and the rotating shaft 16 to rotate, the rotating shaft 16 drives the driving shaft 33 to rotate through the cooperation of the second sprocket 34 and the second chain 35, thereby driving the sludge pushing plate 6 to rotate through the driving shaft 33, so that the sludge pushing plate 6 pushes the sludge on the sludge processing plate 4 into the discharge tube 43, thereby facilitating the processing and discharge of the salvaged sludge.

[0064] The end of the other rotating shaft 16 is fixedly connected to the rotating shaft of the speed increaser 8, the lower surface of the speed increaser 8 is fixedly connected to the fixing plate 36, the fixing plate 36 is horizontally fixedly connected to the inner wall of the outer box body 7, and the generator 9 is fixedly connected to the fixing plate 36, so as to facilitate the conversion of the flow force of the water into electricity, and store the converted electricity through the battery 10, and at the same time transmit the electricity to the heater 5 through the battery 10, so as to facilitate the heating treatment of the salvaged silt and reduce the heat contained in the silt.

[0065] Working principle: The fixing frame 1 is fixed to the bottom of the river channel and located upstream of the curved part of the river channel. At the same time, the first baffle 13 and the trash retaining plate 11 are opposite to the flow direction of the water in the river channel, and the discharge tube 43 is located just above the outer bank of the curved part of the river channel.

[0066] When the river water flows downstream and passes through the fixed frame 1, the flow of the river water pushes the salvage box 3 in the direction of the arc plate 14. During the movement of the salvage box 3, the first chain 18 is driven to rotate, thereby driving the first sprocket 17 and the rotating shaft 16 to rotate through the engagement of the first chain 18 with the first sprocket 17. During the rotation of the rotating shaft 16, one of the rotating shafts 16 drives the rotation of the rotating shaft on the speed increaser 8, and drives the rotation of the rotating shaft on the generator 9 through the output shaft of the speed increaser 8, so that the generator 9 generates electricity and transmits the electricity to the battery 10 for storage, so as to convert the thrust generated by the water on the salvage box 3 when flowing into electricity, and at the same time facilitate the transmission of electricity to the heater 5 through the battery 10.

[0067] The salvage teeth 20 are inserted into the silt at this time. In the process of the salvage box 3 driving the salvage teeth 20 to move, the salvage teeth 20 scrape up the silt, and the salvage box 3 scrapes the silt into the salvage box 3, while the arc plate 14 blocks the scraped silt, so that it is convenient for the salvage box 3 to scrape the silt into the salvage box 3 in the process of the first chain 18 driving the salvage box 3 to move upward. At the same time, in the process of the first chain 18 driving the salvage box 3 to move upward, when the salvage teeth 20 pass through the pollution blocking board 11, the salvage teeth 20 salvage the pollutants intercepted by the pollution blocking board 11, such as leaves floating on the water surface. As the salvage box 3 moves upward, the pollutants salvaged by the salvage teeth 20 slide into the salvage box 3 through the inclined surface of the salvage teeth 20. At the same time, the blocking of the salvage teeth 20 can prevent the salvaged leaves from flowing out of the salvage box 3 with the water flow, thereby realizing the salvage treatment of the pollutants on the water surface of the river.

[0068] When the first chain 18 drives the salvage box 3 to move the upper side of the rotating shaft 16, the pollutants such as leaves and water plants salvaged by the salvage teeth 20 and the silt salvaged in the salvage box 3 slide down to the silt treatment plate 4. When the limit block 25 contacts the baffle 27, the baffle 27 blocks the limit block 25, so that the salvage box 3 slides on the cover plate 22. As the connecting block 19 approaches the limit block 25, the first spring 26 gradually contracts. When the first spring 26 contracts to the minimum length value, the discharge port 21 on the salvage box 3 is opened, and the silt remaining in the salvage box 3 slides down to the silt treatment plate 4 through the discharge port 21. At the same time, during the sliding process of the salvage box 3, its side wall The push block 30 slides on the cover plate 22, thereby pushing the sludge remaining on the cover plate 22 away from the cover plate 22 through the discharge port 21, thereby preventing the sludge from remaining in the cover plate 22 and the salvage box 3. When the connecting block 19 contacts the pushing block 30, the connecting block 19 pushes the inclined surface of the pushing block 30, thereby pushing the pushing block 30 into the limiting cavity 28. In the process of the pushing block 30 moving into the limiting cavity 28, the pushing block 30 pushes the sliding plate 29 to one side of the limiting cavity 28, and drives the blocking rod 27 to move into the limiting cavity 28. When the end of the pushing block 30 is flush with the side wall of the support plate 2, the end of the blocking rod 27 is also flush with the side wall of the support plate 2, thereby facilitating the first chain 18 to drive the salvage box 3 to continue to move.

[0069] When the limit block 25 is separated from the obstruction of the stop rod 27, the first spring 26 pushes the limit block 25 in the direction away from the connecting block 19 through the elastic force of the first spring 26, thereby driving the cover plate 22 and the fixing block 23 to be pulled in the direction of the connecting block 19, so as to facilitate the restoration of the position of the cover plate 22 and facilitate the cover plate 22 to cover the discharge port 21. When the connecting block 19 moves to one side of the push block 30, the push block 30 is separated from the pushing of the connecting block 19, and through the elastic force of the second spring 31, the second spring 31 pushes the sliding plate 29 to one side, and pushes the push block 30 and the stop rod 27 out of the limit cavity 28 through the sliding plate 29, so as to facilitate the restoration of the position of the sliding plate 29, the push block 30 and the stop rod 27.

[0070] The heater 5 is started to heat the sludge treatment plate 4, and the sludge treatment plate 4 transfers heat to the sludge, thereby promoting the evaporation of water in the sludge, making the sludge semi-solidified. During the rotation of the rotating shaft 16, one of the rotating shafts 16 drives the driving shaft 33 to rotate through the cooperation of the second sprocket 34 and the second chain 35, and drives the sludge pushing plate 6 to rotate, so that the semi-solidified sludge is pushed into the discharge tube 43 through the sludge pushing plate 6, and then discharged from the discharge tube 43 to the outer bank of the river bend, thereby reinforcing the river bank height.

[0071] Among them, the upper end surface of the support plate 2 is horizontally fixedly connected with a protective plate 44, one end surface of the protective plate 44 is fixedly connected with a vertical plate 45, the vertical plate 45 is fixedly connected to the side wall of the support plate 2, and the other end of the protective plate 44 is fixedly connected with an inclined plate 46. The sludge treatment plate 4 is located between the vertical plate 45 and the inclined plate 46. The vertical plate 45, the inclined plate 46 and the protective plate 44 can effectively prevent rainwater from entering the sludge treatment plate 4, thereby preventing rainwater from directly washing the dried sludge on the sludge treatment plate 4.

[0072] Embodiment 2

[0073] The following technical features are added on the basis of the first embodiment:

[0074] A river channel silt cleaning device, the cleaning brush 12 includes a rotating rod 37 and bristles 38, the bristles 38 are distributed on the circumferential wall of the rotating rod 37, the end of the rotating rod 37 is rotatably connected to the side wall of the support plate 2, and one end of the rotating rod 37 penetrates the side wall of the support plate 2 and the outer box body 7 and extends into the outer box body 7, the top of the outer box body 7 is fixedly connected with a driving motor 39, the output shaft of the driving motor 39 is fixedly connected to the end of the rotating rod 37, and the wire on the driving motor 39 is electrically connected to the battery 10, there are at least two cleaning brushes 12, and multiple cleaning brushes 12 are horizontally distributed, wherein the rotation direction of the rotating rod 37 on the cleaning brush 12 is opposite to the rotation direction of the rotating shaft 16, and the output shaft of the driving motor 39 is fixedly connected to the end of one of the rotating rods 37, and a third sprocket 47 is fixedly connected to the rotating rod 37, and two adjacent third sprockets 47 are connected by a third chain 48 for transmission, so that the bristles 38 can clean the pollutants such as leaves and water plants remaining on the salvage teeth 20.

[0075] A plurality of water filtering holes are provided on the pollution blocking plate 11, and a connecting plate 40 is fixedly connected to the side wall of the pollution blocking plate 11, and a sliding block 41 is fixedly connected to the side wall of the connecting plate 40, and a sliding groove 42 is provided on the side wall of the support plate 2, and the sliding block 41 is slidably connected in the sliding groove 42, wherein the connecting plate 40 is a buoyancy plate, and the lower end surface of the connecting plate 40 cooperates with the support rod 15, and the buoyancy of the connecting plate 40 makes the connecting plate 40 float on the water surface, and due to the gravity of the pollution blocking plate 11, the lower half of the pollution blocking plate 11 and the connecting plate 40 are located in the river water, and the upper half of the connecting plate 40 and the pollution blocking plate 11 are located on the upper side of the river water surface, so as to facilitate the interception of suspended matter on the river water surface and near the lower half of the pollution blocking plate 11, so that the salvage teeth 20 can salvage some of the suspended matter floating in the river water and the floating matter on the water surface.

[0076] Working principle: When the river water flows, the bottom of the salvage box 3 at the bottom of the first chain 18 has resistance to the river water flow, so that the river water pushes the salvage box 3 to one side during the flow, thereby driving the first chain 18 to rotate. The salvage box 3 at the bottom of the first chain 18 salvages the silt at the bottom of the river channel during the movement, thereby cleaning the silt at the bottom of the river channel. At the same time, the resistance of the salvage box 3 at the bottom of the first chain 18 to the river water flow reduces the flow velocity of the river water, thereby reducing the impact force of the river water flow on the river bank at the curved part of the river channel, thereby reducing the erosion of the river bank outside the curved part of the river channel.

[0077] When the first chain 18 drives the salvage box 3 and the salvage teeth 20 to pass through the trash blocking plate 11, the salvage teeth 20 salvage the floating objects and suspended objects intercepted by the trash blocking plate 11. When the first chain 18 drives the salvage box 3 to move to the upper side of the rotating shaft 16, the drive motor 39 is started at this time. The output shaft of the drive motor 39 drives one of the rotating rods 37 to rotate the plate, and drives the adjacent rotating rod 37 to rotate through the cooperation of the third sprocket 47 and the third chain 48, thereby driving the bristles 38 to rotate. Since the rotation direction of the bristles 38 is opposite to the rotation direction of the rotating shaft 16, during the rotation process of the bristles 38 In the process, the bristles 38 sweep the floating objects and suspended objects remaining on the salvage teeth 20 toward the open end of the salvage box 3, so that the floating objects and suspended objects remaining on the salvage teeth 20 slide down through the open end of the salvage box 3 onto the sludge processing plate 4. Since the sludge salvaged in the salvage box 3 also slides down through the open end of the salvage box 3 onto the sludge processing plate 4, the salvaged floating objects and suspended objects are mixed with the sludge on the sludge processing plate 4. When the sludge is dried by the heater 5, the floating objects and suspended objects are bonded to the sludge, thereby increasing the adhesion and stability between the mud blocks after the sludge is dried.

[0078] When the river water level rises, the buoyancy of the connecting plate 40 drives the trash blocking plate 11 to move upward. When the river water level drops, the connecting plate 40 drives the trash blocking plate 11 to slide downward, so that the height of the trash blocking plate 11 can be adjusted according to the river water level. When the river water level is low and the lower end of the connecting plate 40 contacts the upper end surface of the support rod 15, the support of the supporting rod 15 on the connecting plate 40 creates a certain gap between the lower end surfaces of the connecting plate 40 and the trash blocking plate 11 and the upper end surface of the first baffle 13, so that aquatic organisms such as fish and shrimp can swim downstream through the gap between the trash blocking plate 11 and the first baffle 13.

[0079] Among them, at least two second baffles 49 are arranged on the side wall of the fixing frame 1, one of the second baffles 49 is fixedly connected to the upper surface of the fixing frame 1, and the other second baffle 49 is fixedly connected to the upper surface of the fixing frame 1 through a connecting rod 50, and the connecting rod 50 is located at one end of the fixing frame 1 away from the support plate 2, and a sedimentation box 51 is arranged on the side of the second baffle 49 close to the support plate 2, and the sedimentation box 51 is connected to the fixing frame 1 through existing technical means such as snap buckles, and the second baffle 49 is located downstream of the river channel. During the process of salvaging the silt at the bottom of the river channel by the salvage box 3, the silt at the bottom of the river channel will be stirred, and part of the silt will melt in the flowing water and flow downstream. When the flowing water passes through the second baffle 49, the water flow is blocked by the second baffle 49, thereby reducing the flow speed of the water flow, causing the river water to approach the bottom of the river channel. The flow speed of the water in the lower part is relatively slow, so that the silt dissolved in the water flow is deposited in the sedimentation box 51, and at the same time, the flow speed of the water near the bottom of the river channel is further reduced, and the erosion of the river bank outside the curved part by the water at the bottom of the river channel is further reduced. When there is a lot of silt deposited in the sedimentation box 51, the staff uses existing technical equipment, such as a crane, to lift the sedimentation box 51 and transfer it to the river bank, so that the staff can clean the silt in the sedimentation box 51. By setting two second baffles 49 staggered up and down, not only can the flow speed of the water near the bottom of the river channel be reduced, and the suspended particles contained in the water at the bottom of the river channel be precipitated, but also it is convenient for organisms in the river water, such as fish and shrimp, to swim downstream through the upper side of the second baffle 49 and the lower side of the other second baffle 49, so as to facilitate the survival of aquatic organisms in the river water.

[0080] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
