Description

Technical Field

[0001] This invention relates to the field of water conservancy restoration technology, specifically to a river ecological restoration device for water conservancy projects. Background Technology

[0002] With the continuous advancement of urbanization and rapid industrial development, a large amount of pollutants rich in nutrients, organic matter and heavy metals are gradually deposited at the bottom of the riverbed, forming thick and complex bottom silt. This silt not only seriously weakens the flood control and water storage capacity of the river, but also acts as an internal pollution source to continuously release harmful substances into the water, causing the river water to become black and smelly, and the water quality to deteriorate, seriously damaging the fragile water ecological balance. Therefore, the precise dredging and cleaning of bottom silt has become a crucial part of the current river ecological restoration project. However, in actual sludge dredging operations, traditional excavation or dredging equipment often operates roughly when working underwater, which can easily cause violent agitation of underwater sediment. Once toxic and harmful substances that were originally deposited at the bottom are stirred up over a large area, they will quickly spread to the surrounding areas along the water flow. This will not only make the originally acceptable water body instantly become turbid, but also cause secondary damage to the surrounding unpolluted areas. Secondly, there is the issue of the deployment of water-based equipment. River environments are complex and changeable, and the water surface is easily affected by waves and undercurrents. This requires water-based operation platforms to have extremely high stability and the ability to deploy quickly. Traditional dredging equipment often requires multiple sets of power to control the lowering of the working pipes or robotic arms. It is easy for the mechanical structure to twist, rub, or even jam and interfere with each other due to the inconsistent lowering speeds on the left and right sides. This unsmooth deployment process not only seriously slows down the deployment efficiency of the equipment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a river ecological restoration device for water conservancy projects. It solves the problems that traditional dredging equipment is prone to causing large-scale secondary pollution due to violent stirring of bottom sediment during operation, and the deployment efficiency is often severely slowed down by the structure caused by multiple power controls.

[0007] Preferably, the parallel linkage mechanism includes an auxiliary rocker arm that rotates along both sides of the ship's frame. A stationary guide tube is fixed to the outside of the auxiliary rocker arm, and an embedded screw is embedded inside the stationary guide tube. While the nut end of the nut assembly moves along the side wall of the stationary guide tube, its nut sleeve end is sleeved on the embedded screw.

[0008] Preferably, the extension embedding frame includes an extension synchronization frame, which extends along the interior of the main extension rocker and the auxiliary rocker, and the traction shaft is fixed to the top of the extension synchronization frame.

[0009] Preferably, the synchronous compaction mechanism includes a bidirectional synchronous rod, the two ends of which are hinged to the traction shafts of the extended synchronous frames on both sides, so that the main extended rocker, the auxiliary rocker, and the two sets of extended synchronous frames can move synchronously and in parallel.

[0014] This invention provides a river ecological restoration device for water conservancy projects. It has the following beneficial effects: 1. The device of this invention does not use complex electronic synchronization control, but uses physical structural hard connection to achieve interlocking. When the main hydraulic drive pushes open the main extension rocker on one side, the rocker flips down and directly pulls the traction shaft on it. The traction shaft is connected to the bidirectional synchronization rod in the middle.

Then, the strong suction generated by the pump above flows down the pipe and removes all the silt in these closed spaces, avoiding and reducing the degree of secondary pollution to the water body during the repair operation.

[0016] 3. When the equipment of this invention is retrieved and withdrawn, it also operates in the reverse of mechanical logic. The motor pulls back, the compaction table and the cutter head are smoothly pulled out of the mud pit, the hydraulic rod retracts, the two side frames fold down simultaneously, and finally it is stably stacked on the bow of the ship. The whole process has no unnecessary movements, reducing the operating volume of the equipment and improving deployment portability. Attached Figure Description

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a river ecological restoration device for water conservancy projects, including: a ship frame 1, used for fixing and assembling the structure of the river ecological restoration device for water conservancy projects; The main hydraulic drive unit 2 is located on the hull frame 1 and is used for traction control of the dredging and repair structure deployment. The main hydraulic drive unit 2 is rotatably mounted on the top bow of the hull frame 1. The main hydraulic drive unit 2 is mainly responsible for outputting the driving force for the structure deployment, directly pushing the parallel traction mechanism 4 in front, and driving the repair structure to deploy and retract. The sludge pumping element 3 is located on the hull frame 1 and is used to generate the negative pressure suction required for river sludge suction and output it to the receiving vessel following behind. The sludge pumping element 3 is mounted on the stern of the hull frame 1.

[0021] Please see the appendix Figure 3 - Appendix Figure 7 The parallel traction mechanism 4 is located on the hull frame 1 and is used to form a traction structure on one side of the parallel extension of the cutter suction structure. The parallel traction mechanism 4 is rotatably mounted on the hull frame 1 and close to the sludge pumping element 3. Please see the appendix Figure 3 - Appendix Figure 7 The parallel traction mechanism 4 includes a main extension tilting frame 41, which rotates along the side of the hull frame 1. The prying part at the top is controlled by the telescopic end of the main hydraulic drive 2. The stationary conveying pipe 42 is located inside the main extension tilting frame 41 and below the hull frame 1. The synchronous hose 43 is installed and connected to the bottom end of the main extension tilting frame 41. The prying part at the top of the main extension tilting frame 41 receives the thrust and pull of the telescopic end of the main hydraulic drive 2, causing the main extension tilting frame 41 to flip and unfold downwards to the water surface. At the same time, the stationary conveying pipe 42 inside is unfolded synchronously to provide an overall channel for the mud. The synchronous hose 43 sinks down with the end of the main extension tilting frame 41. The synchronous hose 43 uses its own flexible deformation ability to bend when the main extension tilting frame 41 unfolds and contracts, maintaining the normal use of the mud suction channel and the smooth unfolding and retraction. Please see the appendix Figure 5 - Appendix Figure 7The top end of the stationary conveying pipe 42 is connected to the input end of the sludge pumping element 3 through a conveying hose structure. The stationary conveying pipe 42 is responsible for receiving the high-speed sludge flow pumped up from below and guiding it upward. The conveying hose structure smoothly guides the sludge delivered by the stationary conveying pipe 42 into the input end of the sludge pumping element 3. The conveying hose structure, through its deformable properties, ensures the movement and displacement state between the stationary conveying pipe 42 and the sludge pumping element 3.

[0022] Please see the appendix Figure 3 - Appendix Figure 7 The parallel linkage mechanism 5 is located on the hull frame 1 and works with the main extension tilting frame 41 to form the other side traction structure of the parallel extension of the cutter suction structure. The parallel linkage mechanism 5 is rotatably mounted on the hull frame 1 and moves synchronously with the parallel traction mechanism 4. The parallel linkage mechanism 5 mainly completes the synchronous flipping action on the other side through passive traction. When the parallel traction mechanism 4 is subjected to force and flips, the parallel linkage mechanism 5 performs synchronous rotation and unfolding operation to ensure the stability of the cutter suction structure when it extends into the depth of the silt. Please see the appendix Figure 5 - Appendix Figure 7 The parallel linkage mechanism 5 includes an auxiliary rocker arm 51, which rotates along both sides of the ship frame 1. A stationary guide tube 52 is fixed on the outside of the auxiliary rocker arm 51, and an embedded screw 53 is embedded and rotated inside the stationary guide tube 52. While the nut end of the nut assembly 54 moves along the side wall of the stationary guide tube 52, its nut sleeve end is sleeved on the embedded screw 53. After the auxiliary rocker arm 51 is subjected to traction force, it drives the stationary guide tube 52 to tilt downward as a whole. When the embedded screw 53 starts to rotate, it drives the nut end of the nut assembly 54 to slide down along the side wall of the stationary guide tube 52 to form a linearly controlled extended driving force. Please see the appendix Figure 7 The embedded screw 53 is controlled to rotate by a motor element sealed inside the stationary guide tube 52.

[0023] Please see the appendix Figure 4 - Appendix Figure 7 The extended embedding frame 6 is located on the hull frame 1. Together with the main extended rocker arm 41, the auxiliary rocker arm 51 and the nut assembly 54, it forms a suction and pushing structure that can extend downward or be retracted. There are two sets of extended embedding frames 6, which are respectively mounted on the parallel traction mechanism 4 and the parallel linkage mechanism 5. The two sets of extended embedding frames 6 are responsible for the pressing and pushing operation. When the nut assembly 54 applies a downward sliding thrust, the two sets of extended embedding frames 6 will drive the embedding suction mechanism 8 to descend and rise stably in the form of rectangular points. Please see the appendix Figure 6 - Appendix Figure 7The extended embedding frame 6 includes an extended synchronous frame 61, which extends along the interior of the main extended rocker 41 and the auxiliary rocker 51 respectively. The traction shaft 62 is fixed to the top of the extended synchronous frame 61. After the traction shaft 62 receives the thrust, the extended synchronous frame 61 slides along the internal guide rails of the main extended rocker 41 and the auxiliary rocker 51, converting the displacement force into a thrust on the underlying structure. As the extended synchronous frame 61 slides deeper into the structure.

[0024] Please see the appendix Figure 6 - Appendix Figure 8 The synchronous compaction mechanism 7 is located on the hull frame 1 and works with the traction shaft 62 to pull the synchronous movement of the two sets of parallel extended embedding frames 6. It can also perform synchronous compaction on the silt surface. The synchronous compaction mechanism 7 is correspondingly set between the two sets of extended embedding frames 6 and always remains parallel to the hull frame 1. The synchronous compaction mechanism 7 plays a dual role of synchronous constraint and flattening compaction between the two sets of extended embedding frames 6, and indirectly drives the synchronous movement of the parallel traction mechanism 4 and the parallel linkage mechanism 5. Please see the appendix Figure 7 - Appendix Figure 8 The synchronous compaction mechanism 7 includes a bidirectional synchronous rod 71. The two ends of the bidirectional synchronous rod 71 are hinged to the traction shafts 62 of the extended synchronous frames 61 on both sides, enabling the main extended rocker arm 41, the auxiliary rocker arm 51, and the two sets of extended synchronous frames 61 to move synchronously and parallel. A compaction platform 72 is provided on the outer side of the extended synchronous frame 61, and the compaction platform 72 itself has multiple evenly distributed seepage holes and seepage grooves, while maintaining a horizontal position with the ship's frame 1. The two sides of the compaction platform 72 have an upper inclined plate structure, and the displacement direction is forward. The square is fixed with an arc-shaped end 73. The two ends of the bidirectional synchronous rod 71 are pulled by the two traction shafts 62 on both sides, which transmits the displacement force on one side to the other side, forcing the main extension rocker 41, the auxiliary rocker 51 and the two sets of extension synchronous frames 61 to move synchronously. When the compaction table 72 is pressed down by the bidirectional synchronous rod 71 and comes into contact with the silt, the silt is squeezed and discharged along the seepage hole structure on the surface of the compaction table 72 to remove excess water. The arc-shaped end 73 in front of the compaction table 72 cuts into the mud first when it is displaced, splitting the stubborn mud blocks encountered to both sides and diverting them.

[0025] Please see the appendix Figure 9 - Appendix Figure 10 The embedded cutter suction mechanism 8 is located on the hull frame 1. Together with the stationary conveying pipe 42 and the extended synchronous frame 61, it forms a cutter suction structure that can be embedded deep into the river silt. The embedded cutter suction mechanism 8 is mounted at the bottom of the extended embedded frame 6. The embedded cutter suction mechanism 8 is located at the bottom of the equipment and is responsible for the silt extraction and repair operation. When the extended synchronous frame 61 transmits a huge downward thrust to the embedded cutter suction mechanism 8, the embedded cutter suction mechanism 8 uses its own sharp front end to directly insert into the silt surface and make the entire cutter suction mechanism 8 embedded in the deep viscous silt. Please see the appendix Figure 9 -Appendix Figure 10 The embedded suction mechanism 8 includes a conical base 81, which is hinged to the bottom of two sets of extended synchronous frames 61 and always remains parallel to the hull frame 1. The bottom of the conical base 81 has a pointed conical base plate structure to facilitate easy embedding into the silt. An input sleeve 82 is fixed inside the conical base 81, and a stabilizing arc plate 83 is provided at the front end of the input sleeve 82, so that the stabilizing arc plate 83 and the front end of the conical base 81 form a semi-enclosed flow stabilization area. A suction cutter head 84 is rotatably installed in the flow stabilization area, and a top guide pipe 85 is provided at the top end of the input sleeve 82. The top of the guide tube 85 is connected to the input end of the synchronous hose 43. The conical base 81 remains horizontal under the constraint of the hinge point. The pointed conical base plate at the bottom facilitates the whole body to penetrate deep silt. The high-speed rotation of the cutter head 84 refines the silt. The stabilizing arc plate 83 at the front end of the input sleeve 82 is spliced ​​with the conical base 81 to form a semi-enclosed stabilizing area, which alleviates the water vortex stirred up by the rotation of the cutter head 84 and prevents the silt from splashing and spreading outward. Then, it is forcibly pulled into the input sleeve 82 by negative pressure and enters the synchronous hose 43 upward along the internal channel of the top guide tube 85. Please see the appendix Figure 9 -Appendix Figure 10 The input sleeve 82 has a sealing sleeve 86 fixed inside, and a drive shaft 87 is embedded inside the sealing sleeve 86. The drive shaft 87 is fixed to the output shaft of the suction head 84. At the same time, the sealing sleeve 86 is driven to rotate by a motor element that is sealed and fixed at the tail of the input sleeve 82. When the motor element at the tail of the input sleeve 82 is energized, it outputs rotational torque to the drive shaft 87 inside the input sleeve 82. The drive shaft 87 is sealed by the sealing sleeve 86 to avoid direct contact with the silt and to prevent mud and water from entering the motor.

[0026] Please see the appendix Figure 1 -Appendix Figure 3 The parallel floats 9 are located on the hull frame 1 and are used to provide buoyancy for the entire repair device. The parallel floats 9 are distributed on both sides of the hull frame 1 and mainly use the cavity volume to obtain buoyancy, supporting the hull frame 1 on both sides so that the hull frame 1 floats on the water surface.

[0027] Based on the above technical solution, this embodiment of the invention also provides a working principle of a river ecological restoration device for water conservancy projects: The two sides of the hull frame 1 are supported by the upward buoyancy applied by the parallel floats 9, causing the hull frame 1 to detach from the bottom of the river and float on the surface of the river. The hull frame 1 is displaced on the water surface. The telescopic end of the main hydraulic drive component 2 pulls the prying part at the top of the main extension tilting frame 41. Under this rotational torque, the main extension tilting frame 41 unfolds and flips downwards. The unfolding and flipping action of the main extension tilting frame 41 drives the stationary conveying pipe 42 and the synchronous hose 43 it carries to unfold together. While the main extension tilting frame 41 is rotating and unfolding, the main extension tilting frame 41 drags the extension synchronous frame 61 on one side to flip downwards synchronously. The extension synchronous frame 61 pulls the displacement force The force is applied to the traction shaft 62, which, after being pulled, transmits the tensile force to one end of the bidirectional synchronizing rod 71. The other end of the bidirectional synchronizing rod 71 applies the same tension to the other traction shaft 62, which then transmits the tension to the other extension synchronizing frame 61. Under the tension, the other extension synchronizing frame 61 causes the auxiliary tilting frame 51 of the parallel linkage mechanism 5 to rotate. The auxiliary tilting frame 51 is constrained by the synchronous compaction mechanism 7 and performs an unfolding action around the hull frame 1 in sync with the main extension tilting frame 41. After the parallel traction mechanism 4 and the parallel linkage mechanism 5 have completed their unfolding, the motor component installed in the stationary guide cylinder 52 drives the embedded screw 53 to rotate. After receiving the rotational power, the embedded screw 53... The nut assembly 54 is driven to slide downwards along the side wall of the stationary guide cylinder 52. During the sliding process, the nut assembly 54 directly presses the downward linear thrust it bears onto the two sets of extension embedding frames 6. The extension synchronization frames 61 of the two sets of extension embedding frames 6 are pushed downwards along the interior of the main extension rocker 41 and the auxiliary rocker 51. As the two sets of extension synchronization frames 61 continue to slide downwards, the traction shaft 62 at the top of the extension synchronization frame 61 sinks accordingly. The two sets of traction shafts 62 transmit the downward physical displacement to the bidirectional synchronization rod 71 and the compaction table 72. The compaction table 72 is driven downwards by the bidirectional synchronization rod 71. The compaction table 72 maintains a horizontal posture throughout the entire downward process until it touches the riverbed. The surface of the bottom layer of silt is directly compressed. The arc-shaped end 73 of the compaction platform 72, positioned in front of the platform, first contacts the silt layer. The bottom surface of the compaction platform 72 then presses against the silt surface to compact it. Under pressure, the water inside the silt surges upward, penetrating the multiple seepage holes and channels in the structure of the compaction platform 72 and draining away from the silt layer, forming a temporary compacted state. During the same time that the compaction platform 72 is pressing and compacting the silt surface, two sets of extended synchronous frames 61 extend downward, transmitting the downward thrust to the embedded suction mechanism 8 at the bottom of the extended embedded frame 6. The conical base 81 of the embedded suction mechanism 8 bears the huge downward load, and its pointed conical base plate structure pierces through the surface silt, entering the viscous silt and then completely sinking into the bottom layer of the riverbed.When the conical base 81 enters the deep silt, the motor component sealed at the tail of the input sleeve 82 starts. The output shaft of this motor component transmits torque to the drive main shaft 87 nested inside the sealing sleeve 86. The blades of the suction head 84 cut and crush the deep silt blocks. The stabilizing arc plate 83 installed at the front end of the input sleeve 82 is connected to the front end of the conical base 81, forming a semi-enclosed flow stabilization zone, which slows down the water vortex caused by the cutting of the suction head 84 and prevents the silt from spreading indiscriminately. The upper part fits... The compression barrier formed by the compaction platform 72 also prevents deep agitation from spreading to the water body. At the same time, the sludge pumping element 3 starts to operate, and the suction force it generates flows into the top port of the stationary conveying pipe 42 along the conveying hose structure. The negative pressure suction force extends along the cavity of the stationary conveying pipe 42 to the bottom end, and the synchronous hose 43 guides this suction force into the top guide pipe 85. The top guide pipe 85 then transmits the negative pressure suction force into the interior of the input sleeve 82, and the suction port of the input sleeve 82 releases a vacuum. The suction continuously draws in the mixed slurry cut by the cutter head 84, drawing it into the input sleeve 82. The slurry then flows along the guide of the input sleeve 82 into the top guide pipe 85, then through the flexible channel of the synchronous hose 43, into the internal channel of the stationary conveying pipe 42 and the conveying hose structure, and finally into the chamber of the sludge pumping element 3. Finally, the slurry is transported along the discharge pipe to the following receiving vessel. When structural retraction and removal are required, the extended synchronous frame 61 extends along the main extended frame. The guide rails of 41 and auxiliary rocker arm 51 retract upwards. As the extended synchronous frame 61 slides upwards, it causes the traction shaft 62, bidirectional synchronous rod 71, and compaction platform 72 to detach from the silt surface and silt layer. The upward pulling force of the extended synchronous frame 61 also pulls the conical base platform 81 out of the deep silt pit. The main hydraulic drive component 2 pushes the prying part of the main extended rocker arm 41, causing the main extended rocker arm 41 and auxiliary rocker arm 51 to be pulled forward and retract. All components return to their original positions and remain stationary at the front end of the hull frame 1.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
