Description

Technical Field

[0001] The invention belongs to the field related to reservoir management technology, and more specifically relates to a reservoir bottom mud purification treatment device. Background Art

[0002] The reservoir sediment purification treatment device is a device for cleaning the silt at the bottom of the reservoir. Reservoir desilting removes the silt and debris at the bottom of the reservoir, restores the water storage space to improve flood control, water supply and power generation capabilities, while reducing pollutant release, improving water quality and repairing aquatic ecology, ensuring the safety of dams and water transfer facilities, extending the life of the project, and ultimately achieving sustainable use of water resources.

[0003] The patent document with announcement number CN111364544A records a reservoir dredging device, including a hull, a lifting and contracting pipe and a separation cylinder. The top of the lifting and contracting pipe is connected to one end of the water inlet pipe through a shaft seal, and the other end of the water inlet pipe is connected to the separation cylinder. The middle position of the bottom of the separation cylinder is connected to a mud outlet pipe, and the middle position of the top of the separation cylinder is connected to a mounting cylinder. A driving motor is fixedly installed on the outer top of the mounting cylinder, and a water pump is connected to the side wall of the mounting cylinder. A vertical rotating shaft is arranged inside the separation cylinder and the mounting cylinder. The fixing bolts pass through the radial position of the filter plate to fix the filter plate to the bottom of the mounting cylinder. A spring is nested on the fixing bolts below the filter plate, and a number of pressing rods are fixedly arranged on the side wall of the rotating shaft above the filter plate, and a number of protruding blocks are fixedly arranged on the radial position of the upper surface of the filter plate below the pressing rods.

[0004] The above-mentioned reservoir dredging device has certain shortcomings when in use. The traditional reservoir dredging device directly uses extraction to clean the bottom silt. During operation, the silt will diffuse during the extraction process, making the water turbid and affecting the water quality. At the same time, affected by the density of the silt itself, the resistance of the bottom extraction structure of the reservoir dredging device during movement is increased. At the same time, the silt extraction depth cannot be flexibly controlled, and the functionality is single. Summary of the invention

[0005] The purpose of the present invention is to provide a reservoir sediment purification treatment device which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. Traditional reservoir dredging devices directly use extraction to clean the bottom silt. During operation, the silt will diffuse during the extraction process, making the water turbid and affecting the water quality. At the same time, due to the influence of the silt's own density, the reservoir dredging device increases the resistance of its bottom extraction structure when moving. At the same time, it cannot flexibly control the silt extraction depth and has a single functionality.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] A reservoir sediment purification treatment device comprises a floating boat and a dredging cover, wherein the dredging cover is hoisted at the lower part of the floating boat, and the floating boat and the dredging cover are connected to each other by four hoisting ropes, one end and the bottom of the dredging cover are open structures, two groups of side rotating plates are movably installed at one end of the dredging cover, and the two groups of side rotating plates are symmetrically arranged, and the outer surfaces of one side of the two groups of side rotating plates are both arranged in a V-shape and inclined, and adjustment plates are movably installed on the outer surfaces of both sides of the dredging cover, and both ends of the adjustment plates are acute-angle structures, a suction port is arranged at the middle position of the inner side of the dredging cover, and a first capstan and a second capstan are respectively arranged on both sides of the suction port in the dredging cover, and the first capstan and the second capstan are symmetrically arranged.

[0010] As a further technical solution of the present invention, a driver is installed at one end of the first capstan and the second capstan, the outer surfaces of the first capstan and the second capstan are in a spiral structure, and one end of the first capstan and the second capstan are in a conical structure, and two groups of motors are arranged inside the driver, and the first capstan and the second capstan are driven independently by the two groups of motors. When the dredging hood sinks into the silt, the rotation of the first capstan and the second capstan is utilized to drive the dredging hood through the spiral structure, so that the dredging hood moves in the silt, and at the same time, the first capstan or the second capstan is controlled separately to complete the steering operation of the dredging hood.

[0011] As a further technical solution of the present invention, a material conveying turntable is movably installed at the middle position of the inner side of the dredging hood, a pump body used in conjunction with the dredging hood is arranged inside the floating boat, the dredging hood and the pump body are connected by a silt extraction pipe, a docking socket is installed on one side of the adjusting plate, the adjusting plate and the docking socket are movably connected by a rotating rod, and the state of the dredging hood during movement can be adjusted by the setting of the adjusting plate. When the dredging hood sinks into the silt, the suction port of the dredging hood generates suction by starting the pump body and utilizing the setting of the silt extraction pipe, thereby absorbing the silt at the bottom of the reservoir. The setting of the dredging hood can effectively limit the suction range, so that the suction is concentrated inside the dredging hood, which can effectively improve its silt suction effect, avoid diffusion during the silt suction process, and prevent water turbidity.

[0012] As a further technical solution of the present invention, a fixed backing plate is movably installed at one end of the side rotating plate, the side rotating plate and the side wall of the dredging cover are connected and fixed by the fixed backing plate, and the side rotating plate and the fixed backing plate are movably connected by a hinge, and a docking ear used in conjunction with a lifting rope is provided at the upper end of the dredging cover. The user can switch the use state of the side rotating plate by controlling the use angle of the side rotating plate. When the side rotating plate and the dredging cover are in a vertical state, the side rotating plate faces the silt head-on, and the side edge of the side rotating plate is in a V-shaped state. The silt cleaning cover has a shaped inclined structure. When the side rotating plates move, the side rotating plates can be broken away from the silt, so that the silt is separated up and down from the sides of the side rotating plates. When the silt cleaning cover moves, the silt cleaning cover can be stabilized within a fixed depth of the silt to prevent the silt cleaning cover from tilting up or down. Secondly, when the side rotating plates and the silt cleaning cover are at an obtuse angle, an eight-shaped structure is formed between the two groups of side rotating plates, which gathers the silt in the front section of the side rotating plates, thereby guiding the silt on both sides into the interior of the silt cleaning cover, thereby improving the silt cleaning effect of the silt cleaning cover.

[0013] As a further technical solution of the present invention, an electric strut is movably installed between the side rotating plate and the fixed support plate. The side rotating plate and one end of the electric strut as well as the fixed support plate and the electric strut are movably connected. The electric strut can be used to drive the side rotating plate, so that the side rotating plate rotates under the action of the hinge, thereby adjusting the angle between the side rotating plate and the fixed support plate.

[0014] As a further technical solution of the present invention, a conical head is spliced ​​and installed on the outer surface of one end of the side rotating plate, and the side rotating plate and the conical head are docked and fixed by a docking block. When the electric support rod drives the side rotating plate so that the sides of the side rotating plate and the dredging cover are in a straight state, the setting of the conical head can reduce the resistance at the end of the side rotating plate and improve the movement effect of the side rotating plate in the silt.

[0015] As a further technical solution of the present invention, a docking slot for cooperating with a docking block is provided at the middle position of one end of the side rotating plate, and a fixing rod is provided on the outer surface of the side edge of the fixed support plate. The fixed support plate and the dredging cover are fixed by the fixing rod, and the docking slot fixes the docking block, thereby completing the splicing and fixation of the conical head.

[0016] As a further technical solution of the present invention, the middle part of the floating boat is a rectangular hollow structure, and a support frame is fixedly installed on the outer surface of the upper end of the floating boat, and two groups of winders used in conjunction with the lifting ropes are arranged on the upper end of the support frame. The two groups of winders are used to control the two lifting ropes respectively, so that the use state of the dredging cover can be controlled. When the two lifting ropes at the front end are longer and the two lifting ropes at the rear end are shorter, one end of the dredging cover is tilted downward, and the dredging cover can be inserted into the silt when the dredging cover moves. When the two lifting ropes at the front end are shorter and the two lifting ropes at the rear end are longer, one end of the dredging cover is tilted upward, and the dredging cover can be moved out of the silt when the dredging cover moves.

[0017] As a further technical solution of the present invention, a silt discharge pipe is arranged at the middle position of the rear end of the floating boat, and a reel for cooperating with the silt discharge pipe is arranged at the upper end of the floating boat. The user can complete the winding or releasing operation of the silt discharge pipe by rotating the reel. One end of the silt discharge pipe is connected to the discharge end of the pump body. When the silt extraction pipe extracts the silt, the pump body is used to discharge the silt outward through the silt discharge pipe.

[0018] As a further technical solution of the present invention, a plurality of groups of floaters are fixedly installed on the outer surface of the silt discharge pipe, and the interior of the floaters is a hollow structure. The plurality of groups of floaters are evenly distributed on the outer surface of the silt discharge pipe. By utilizing the arrangement of the plurality of groups of floaters, the silt discharge pipe floats on the water surface, thereby preventing the silt discharge pipe from sinking.

[0019] Beneficial effects of the present invention:

[0020] 1. By setting up a dredging cover and a suspension rope, the reservoir bottom mud purification treatment device has a semi-closed sludge cleaning structure when in use, so as to avoid the diffusion of sludge during cleaning, prevent secondary pollution of the water body, and improve its cleaning effect;

[0021] During operation, two groups of motors are used to independently drive the first capstan and the second capstan. When the dredging cover sinks into the silt, the rotation of the first capstan and the second capstan is used to drive the dredging cover through the spiral structure, so that the dredging cover moves in the silt. At the same time, the first capstan or the second capstan can be controlled separately to complete the steering operation of the dredging cover. The user can complete the winding or releasing operation of the silt discharge pipe by rotating the unwinding drum. The silt discharge pipe is floated on the water surface by the setting of several groups of floaters to prevent the silt discharge pipe from sinking. One end of the silt discharge pipe is connected to the discharge end of the pump body. When the silt extraction pipe extracts silt, the silt is discharged outward through the silt discharge pipe by the pump body. By starting the pump body and using the setting of the silt extraction pipe, the silt discharge pipe The suction port of the silt hood generates suction, thereby absorbing the silt at the bottom of the reservoir. The setting of the silt cleaning hood can effectively limit the suction range, so that the suction is concentrated inside the silt cleaning hood, which can effectively improve its silt suction effect, avoid diffusion during the silt suction process, and prevent water turbidity. Two sets of winders are used to control the two lifting ropes respectively, so that the use status of the silt cleaning hood can be controlled. When the two lifting ropes at the front end are longer and the two lifting ropes at the rear end are shorter, one end of the silt cleaning hood is tilted downward, and when the silt cleaning hood moves, the silt cleaning hood can be inserted into the silt. When the two lifting ropes at the front end are shorter and the two lifting ropes at the rear end are longer, one end of the silt cleaning hood is tilted upward, and when the silt cleaning hood moves, the silt cleaning hood can be moved out of the silt.

[0022] 2. By setting up the side rotating plate, when the reservoir sediment purification treatment device is used, the use of the dredging cover is optimized, the sludge gathering effect is improved, and the dredging cover is kept in a stable moving state;

[0023] When in use, the user can switch the use state of the side rotating plate by controlling the use angle of the side rotating plate. The side rotating plate can be driven by the electric strut to make the side rotating plate rotate under the action of the hinge, thereby adjusting the angle between the side rotating plate and the fixed support plate. When the side rotating plate and the dredging cover are in a vertical state, the side rotating plate faces the silt head-on, and the side edges of the side rotating plate are in a V-shaped inclined structure. When the side rotating plate moves, the side rotating plate can be broken from the silt, so that the silt is separated up and down by the side edges of the side rotating plate. When the dredging cover moves, the dredging cover can be stabilized within a fixed depth of the silt to prevent the dredging cover from tilting up or down. Secondly, when the side rotating plate and the dredging cover are in an obtuse angle state, the two sets of side rotating plates are in an eight-shaped structure, which gathers the silt in the front section of the side rotating plate, thereby guiding the silt on both sides into the interior of the dredging cover, thereby improving the silt cleaning effect of the dredging cover.

[0024] 3. By setting the adjustment plate, when the reservoir sediment purification device is used, the movement effect of the dredging cover in the silt is improved, and the influence of the silt at different depths on the dredging cover is reduced;

[0025] During operation, the dredging hood is placed in the silt to carry out silt extraction operations. When the sling rope directly lifts the dredging hood, the silt resistance will affect the lifting effect of the dredging hood. By controlling the angle of the adjusting plate, the dredging hood can be moved out of the silt when the dredging hood moves. When it is lifted, the motor in the docking seat is used to drive the rotating rod, so that the rotating rod drives the adjusting plate to rotate. When one end of the adjusting plate is in an upward tilted state, the adjusting plate drives the dredging hood to tilt upward in the silt, so that the dredging hood is quickly moved out of the silt. Secondly, when the dredging hood moves, the adjusting plate can be rotated to a horizontal state, so that the dredging hood can move stably within the corresponding depth. When the dredging hood is stuck in the silt, the high-speed rotation of the adjusting plate can boost the dredging hood and quickly get it out of trouble. BRIEF DESCRIPTION OF THE DRAWINGS

When the dredging hood 4 sinks into the silt, the rotation of the first reel 2 and the second reel 16 is utilized to drive the dredging hood 4 through the spiral structure, so that the dredging hood 4 moves in the silt, and at the same time, the first reel 2 or the second reel 16 is controlled separately to complete the steering operation of the dredging hood 4.

[0039] A material conveying rotating plate 17 is movably installed at the middle position of the inner side of the dredging hood 4, and a pump body used in conjunction with the dredging hood 4 is arranged inside the floating boat 8. The dredging hood 4 and the pump body are connected by a silt extraction pipe 5. A docking card seat 19 is installed on one side of the adjusting plate 3, and the adjusting plate 3 and the docking card seat 19 are movably connected by a rotating rod 18. The setting of the adjusting plate 3 can be used to adjust the state of the dredging hood 4 when it moves. When the dredging hood 4 sinks into the silt, by starting the pump body and using the setting of the silt extraction pipe 5, the suction port 15 of the dredging hood 4 generates suction, thereby absorbing the silt at the bottom of the reservoir. The setting of the dredging hood 4 can effectively limit the suction range, so that the suction is concentrated inside the dredging hood 4, which can effectively improve its silt suction effect, avoid diffusion during the silt suction process, and prevent water turbidity.

[0040] To improve the sludge cleaning effect, Figure 5 As shown, a fixed backing plate 22 is movably installed at one end of the side rotating plate 1, and the side rotating plate 1 and the side wall of the dredging cover 4 are connected and fixed by the fixed backing plate 22, and the side rotating plate 1 and the fixed backing plate 22 are movably connected by a hinge 21. The upper end of the dredging cover 4 is provided with a docking ear 13 used in conjunction with the lifting rope 6. The user can switch the use state of the side rotating plate 1 by controlling the use angle of the side rotating plate 1. When the side rotating plate 1 and the dredging cover 4 are in a vertical state, the side rotating plate 1 faces the silt head-on, and the side of the side rotating plate 1 is inclined in a V shape. Structure, when the side rotary plate 1 moves, the side rotary plate 1 can be broken from the silt, so that the silt is separated up and down from the side of the side rotary plate 1. When the dredging cover 4 moves, the dredging cover 4 can be stabilized in a fixed depth of the silt to prevent the dredging cover 4 from tilting up or down. Secondly, when the side rotary plate 1 and the dredging cover 4 are in an obtuse angle state, the two groups of side rotary plates 1 form an eight-shaped structure, which has a gathering effect on the silt in the front section of the side rotary plate 1, thereby guiding the silt on both sides into the interior of the dredging cover 4, thereby improving the silt cleaning effect of the dredging cover 4.

[0041] like Figure 6As shown, an electric strut 23 is movably installed between the side rotating plate 1 and the fixed support plate 22, and the side rotating plate 1 and one end of the electric strut 23 as well as the fixed support plate 22 and the electric strut 23 are all movably connected. The electric strut 23 can be used to drive the side rotating plate 1, so that the side rotating plate 1 rotates under the action of the hinge 21, thereby adjusting the angle between the side rotating plate 1 and the fixed support plate 22.

[0042] like Figure 7 As shown, a conical head 20 is spliced ​​and installed on the outer surface of one end of the side rotary plate 1, and the side rotary plate 1 and the conical head 20 are docked and fixed by a docking block 24. When the electric support rod 23 drives the side rotary plate 1, so that the side edges of the side rotary plate 1 and the dredging cover 4 are in a straight state, the setting of the conical head 20 can reduce the resistance at the end of the side rotary plate 1 and improve the movement effect of the side rotary plate 1 in the silt.

[0043] A docking slot 26 for cooperating with the docking block 24 is provided at the middle position of one end of the side rotating plate 1, and a fixing rod 25 is provided on the outer surface of the side edge of the fixed support plate 22. The fixed support plate 22 and the dredging cover 4 are fixed by the fixing rod 25, and the docking slot 26 fixes the docking block 24, so as to complete the splicing and fixation of the conical head 20.

[0044] The middle part of the floating boat 8 is a rectangular hollow structure, and a support frame 12 is fixedly installed on the outer surface of the upper end of the floating boat 8, and two groups of winders 7 used in conjunction with the lifting ropes 6 are arranged on the upper end of the support frame 12. The two groups of winders 7 are used to control the two lifting ropes 6 respectively, so that the use state of the dredging cover 4 can be controlled. When the two lifting ropes 6 at the front end are longer and the two lifting ropes 6 at the rear end are shorter, one end of the dredging cover 4 is tilted downward, and when the dredging cover 4 moves, the dredging cover 4 can be inserted into the silt. When the two lifting ropes 6 at the front end are shorter and the two lifting ropes 6 at the rear end are longer, one end of the dredging cover 4 is tilted upward, and when the dredging cover 4 moves, the dredging cover 4 can be moved out of the silt.

[0045] A silt discharge pipe 11 is provided at the middle position of the rear end of the floating boat 8, and a reel 9 used in conjunction with the silt discharge pipe 11 is provided at the upper end of the floating boat 8. The user can complete the winding or releasing operation of the silt discharge pipe 11 by rotating the reel 9. One end of the silt discharge pipe 11 is connected to the discharge end of the pump body. When the silt extraction pipe 5 extracts silt, the silt is discharged outward through the silt discharge pipe 11 by using the pump body.

[0046] A plurality of groups of floaters 10 are fixedly installed on the outer surface of the silt discharge pipe 11, and the interior of the floaters 10 is a hollow structure. The plurality of groups of floaters 10 are evenly spaced and distributed on the outer surface of the silt discharge pipe 11. By setting the plurality of groups of floaters 10, the silt discharge pipe 11 floats on the water surface, preventing the silt discharge pipe 11 from sinking.

[0047] When in use, by setting the dredging cover 4 and the suspension rope 6, the reservoir bottom mud purification treatment device has a semi-closed sludge cleaning structure when in use, so as to avoid the diffusion of sludge during cleaning, prevent secondary pollution of the water body, and improve its cleaning effect;

[0048] During operation, two groups of motors are used to independently drive the first capstan 2 and the second capstan 16. When the dredging cover 4 sinks into the silt, the rotation of the first capstan 2 and the second capstan 16 is used to drive the dredging cover 4 through the spiral structure, so that the dredging cover 4 moves in the silt. At the same time, the first capstan 2 or the second capstan 16 is controlled separately to complete the steering operation of the dredging cover 4. The user can complete the winding or releasing operation of the silt discharge pipe 11 by rotating the unwinding drum 9. By setting up several groups of floaters 10, the silt discharge pipe 11 floats on the water surface to prevent the silt discharge pipe 11 from sinking. One end of the silt discharge pipe 11 is connected to the discharge end of the pump body. When the silt extraction pipe 5 extracts silt, the silt is discharged outward through the silt discharge pipe 11 by the pump body. By starting the pump body, the silt extraction pipe 5 is used to extract silt. The suction port 15 of the silt cleaning hood 4 is configured to generate suction, thereby absorbing the silt at the bottom of the reservoir. The configuration of the silt cleaning hood 4 can effectively limit the suction range, so that the suction is concentrated inside the silt cleaning hood 4, which can effectively improve its silt suction effect, avoid diffusion during the silt suction process, and prevent water turbidity. Two sets of winders 7 are used to control the two suspension ropes 6 respectively, so that the use state of the silt cleaning hood 4 can be controlled. When the two suspension ropes 6 at the front end are longer and the two suspension ropes 6 at the rear end are shorter, one end of the silt cleaning hood 4 is tilted downward. When the silt cleaning hood 4 moves, the silt cleaning hood 4 can be inserted into the silt. When the two suspension ropes 6 at the front end are shorter and the two suspension ropes 6 at the rear end are longer, one end of the silt cleaning hood 4 is tilted upward. When the silt cleaning hood 4 moves, the silt cleaning hood 4 can be moved out of the silt.

[0049] By providing the side rotating plate 1, when the reservoir bottom mud purification treatment device is used, the use of the dredging cover 4 is optimized, the dredging hood 4 is improved, the dredging hood 4 is kept in a stable moving state;

[0050] When in use, the user can switch the use state of the side rotating plate 1 by controlling the use angle of the side rotating plate 1. The side rotating plate 1 can be driven by the electric support rod 23. The wire structure of the electric support rod 23 is bundled with the silt extraction pipe 5. A generator is installed on the upper end of the floating boat 8, so that the side rotating plate 1 rotates under the action of the hinge 21, thereby adjusting the angle between the side rotating plate 1 and the fixed support plate 22. When the side rotating plate 1 and the silt removal cover 4 are in a vertical state, the side rotating plate 1 faces the silt head-on, and the side of the side rotating plate 1 is in a V-shaped inclined structure. When the side rotary plate 1 moves, the side rotary plate 1 can be broken from the silt, so that the silt is separated from the upper and lower sides of the side rotary plate 1. When the silt cleaning cover 4 moves, the silt cleaning cover 4 can be stabilized in a fixed depth of the silt to prevent the silt cleaning cover 4 from tilting up or down. Secondly, when the side rotary plate 1 and the silt cleaning cover 4 are in an obtuse angle state, the two groups of side rotary plates 1 form an eight-shaped structure, which plays a role in gathering the silt in the front section of the side rotary plate 1, thereby guiding the silt on both sides into the interior of the silt cleaning cover 4, and improving the silt cleaning effect of the silt cleaning cover 4;

[0051] By setting the adjustment plate 3, when the reservoir bottom mud purification treatment device is used, the moving effect of the dredging cover 4 in the sludge is improved, and the influence of the sludge at different depths on the dredging cover 4 is reduced;

[0052] When the silt cleaning cover 4 is moved, the silt cleaning cover 4 can be lifted up by the lifting rope 6. When the silt cleaning cover 4 is lifted up, the silt resistance can affect the lifting effect of the silt cleaning cover 4. By controlling the angle of the adjusting plate 3, the silt cleaning cover 4 can be moved out of the silt when the silt cleaning cover 4 moves. When the silt cleaning cover 4 is lifted up, the silt cleaning cover 4 can be lifted up by the lifting rope 6.
