[0001] The invention relates to the technical field of river management, in particular to a cyclone sediment separation device used for river management. Background Art

[0002] With the rapid economic development and the continuous increase of human activities, rivers are facing more and more serious sedimentation problems. Factors such as soil erosion, river sand mining, and construction have caused a large amount of sediment to enter the river, causing the riverbed to rise continuously, the river channel to narrow, and the water flow to be blocked. This not only affects the ecological environment of the river and reduces the river's flood discharge capacity, but also poses a threat to the surrounding infrastructure and the safety of people's lives and property.

[0003] At present, traditional river management methods mainly include manual dredging, mechanical dredging and embankment construction for flood control. However, these methods have many limitations. Manual dredging is inefficient, labor-intensive, and costly, and can only be carried out in a small area, which cannot meet the needs of large-scale river management. Although mechanical dredging is more efficient, the equipment is large and the operation is complicated, which can easily cause damage to the river channel. At the same time, it will also generate a lot of noise and dust pollution. Embankment construction for flood control can only temporarily alleviate the threat of floods, but cannot fundamentally solve the problem of river siltation.

[0004] Therefore, in order to solve the problem of river siltation and improve the efficiency and effect of river management, a new type of cyclone silt separation device for river management is urgently needed. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-9 The present invention provides a technical solution: a cyclone sediment separation device for river management, comprising a main floating ship 1 and an auxiliary floating ship 2, a plurality of brackets 11 are fixedly installed on the top of the main floating ship 1, a sediment processing mechanism is arranged on the top of the bracket 11, and the sediment processing mechanism comprises: A traction assembly 4 is arranged between the bracket 11 and the top of the auxiliary floating vessel 2; A suspension component 5, arranged on the outer surface of the traction component 4; A limit assembly 6 is arranged on the outer surface of the suspension assembly 5; The sand suction component 7 is arranged on the top of the bracket 11. The sand suction component 7 includes a pipe rack 71 and a sand suction pump 710. A hollow tube 72 is rotatably installed on the inner wall of the pipe rack 71. A connector 74 is installed on the outer wall of the hollow tube 72. One end of the connector 74 is connected to the inside of the hollow tube 72. A hose 76 is fixedly connected to the other end of the connector 74. The hose 76 is wound on the surface of the hollow tube 72. One end of the hose 76 is fixedly connected to a sand suction head 77. A pipe disc 73 for limiting the hose 76 is symmetrically installed on the outer wall of the hollow tube 72. One end of the hollow tube 72 passes through the inner wall of the pipe rack 71 and extends outward. A sand suction pipe 711 is installed at the water inlet of the sand suction pump 710. A swivel joint 712 is provided at one end of the sand suction pipe 711. The swivel joint 712 is connected to one end of the hollow tube 72. The cyclone separation component 8 is arranged on the top of the bracket 11; The liquid supply assembly 9 is arranged on the top of the bracket 11 .

[0023] The water-sand mixture in the riverbed can be extracted by the sand suction pump 710, and the water-sand mixture first enters the sand suction head 77, then passes through the hose 76, the hollow tube 72, the sand suction pipe 711 in sequence, and finally output to the coarse filtering section at the rear of the main floating ship 1 through the water outlet of the sand suction pump 710 and the sand outlet pipe 713. The hollow tube 72 can still maintain a good connection with the sand suction pipe 711 during the rotation process through the rotating joint 712, ensuring the smooth transportation of the water-sand mixture. The flexibility and the characteristics of the hose 76 that can be released and retracted enable the sand suction head 77 to adapt to different riverbed terrains and depths, thereby improving the sand suction efficiency.

[0024] like Figure 1-3 As shown, thrusters 3 are provided at the bottom of the main pontoon 1 and the auxiliary pontoon 2. The main pontoon 1 and the auxiliary pontoon 2 are arranged in parallel. The thrusters 3 at the bottom of the main pontoon 1 and the auxiliary pontoon 2 enable the device to move freely in the river to reach the area to be treated.

[0025] like Figure 3 As shown, a filter plate 12 is installed at the rear position of the inner wall of the main floating vessel 1, and a partition plate 13 is installed at the front position of the inner wall of the main floating vessel 1. The filter plate 12 and the partition plate 13 divide the interior of the main floating vessel 1 into three sections, namely a coarse filtration section at the rear, which is used to receive the water-sand mixture output by the sand suction component 7, a section to be processed in the middle, which is used to receive the water-sand mixture filtered by the coarse filtration section, and a sediment collection section at the front, which is used to receive the sediment processed by the cyclone separation component 8. The water-sand mixture flows to the section to be processed through the pores on the filter plate 12 for preliminary filtration. Some relatively large sediment particles that are easy to clog subsequent processing equipment are isolated in the coarse filtration section by the filter plate 12, thereby reducing the possibility of hard impurities entering subsequent equipment.

[0026] like Figure 4As shown, the traction assembly 4 includes two fixing frames 41, one of which is installed on the top of the bracket 11, and the other fixing frame 41 is installed on the top of the auxiliary floating boat 2. A rotating shaft 42 can be rotatably installed between the inner walls of the two fixing frames 41, and two steel cables 45 are wound together between the outer walls of the two rotating shafts 42, that is, the two rotating shafts 42 are connected by the two steel cables 45, and the outer wall of the rotating shaft 42 is installed with a plurality of rollers 43 for limiting the steel cables 45. A first motor 44 is installed on the outer wall of the fixing frame 41 for driving the rotating shaft 42 to rotate, and the main floating boat 1 and the auxiliary floating boat 2 are connected through the two rotating shafts 42 and the steel cables 45. The length of the steel cables 45 is adjusted under the drive of the first motor 44 to achieve traction of the suspension assembly 5, and at the same time, it can drive the suspension assembly 5 to move horizontally on the river surface, so that the sand suction head 77 can shuttle back and forth between the main floating boat 1 and the auxiliary floating boat 2 when sucking sediment, so as to ensure the cleaning effect of sediment at the bottom of the river.

[0027] like Figure 5 As shown, the suspension assembly 5 includes two connecting plates 51, the tops of the two connecting plates 51 are symmetrically fixedly connected with connecting columns 52, the top of each connecting column 52 is fixedly connected with a clamp 53, the clamp 53 is sleeved on the outer surface of the steel cable 45, the connecting plates 51 and the suspension frame 54 are vertically distributed, the bottoms of the two connecting plates 51 are fixedly installed with the suspension frame 54, the inner wall of the suspension frame 54 is fixedly installed with a U-shaped frame 55 near the bottom, the inner wall of the U-shaped frame 55 is rotatably installed with an extension shaft 56, and the extension shaft 56 is distributed parallel to the connecting plates 51, the two ends of the extension shaft 56 respectively penetrate the inner wall of the U-shaped frame 55 and extend outward, the outer wall of the extension shaft 56 is fixedly sleeved with a pulley 57 near the middle, when the sand suction head 77 sinks or rises, the extension shaft 56 rotates due to the friction generated by the contact between the hose 76 and the pulley 57, thereby driving the winding roller 61 to rotate, so as to realize the release or reeling of the limiting rope 64 without the need for an additional power source.

[0028] like Figure 5 As shown, the limiting assembly 6 includes a winding roller 61 and a support rod 62, and the number of the winding roller 61 and the support rod 62 is set to two. The two winding rollers 61 are respectively fixed on the two end faces of the extension shaft 56, and the two support rods 62 are respectively fixed on the two side surfaces of the U-shaped frame 55, and the support rods 62 are distributed in parallel with the extension shaft 56. The end of the support rod 62 is fixedly connected to the limiting ring 63, and the limiting ring 63 is arranged below the winding roller 61. A limiting rope 64 is wound inside the winding roller 61, and one end of the limiting rope 64 passes through the limiting ring 63 and extends downward. The traction of the limiting rope 64 on the sand suction head 77 can effectively prevent the sand suction head 77 from rotating during movement, ensuring that the sand suction head 77 always contacts the mud on the riverbed at a suitable angle, thereby improving the sand suction efficiency and stability.

[0029] like Figure 6 and Figure 7 As shown, a second motor 75 is installed on the outer surface of the pipe rack 71 for driving the hollow pipe 72 to rotate, a sand suction pump 710 is fixedly installed on the top of the bracket 11, a sand outlet pipe 713 is installed at the water outlet of the sand suction pump 710, and the sand outlet pipe 713 is connected to the coarse filtering section at the rear of the main floating ship 1, and the sand suction head 77 is in direct contact with the silt on the riverbed. Under the strong suction force of the sand suction pump 710, the water-sand mixture can be sucked in quickly and effectively.

[0030] like Figure 6-8 As shown, the other end of the hose 76 passes through the inner side of the U-shaped frame 55 and naturally hangs down, and the surface of the hose 76 contacts the pulley 57, the sand suction head 77 is vertically distributed with the extension shaft 56, and the top of the sand suction head 77 is symmetrically fixedly connected with a column 78 near the edge, and the top of the column 78 is fixedly connected with a ring 79, and the ring 79 is fixedly connected to one end of the limiting rope 64. The connection between the sand suction head 77 and the limiting rope 64 is realized by the ring 79, so that the sand suction head 77 can maintain a stable posture.

[0031] like Fig. 9 As shown, the cyclone separation assembly 8 includes a cylindrical shell 81, a feed pipe 82 is installed on the outer surface of the cylindrical shell 81 along the tangential direction, one end of the feed pipe 82 is connected to the inside of the cylindrical shell 81, an overflow pipe 85 is installed on the top of the cylindrical shell 81, the bottom end of the overflow pipe 85 is connected to the inside of the cylindrical shell 81, the top of the overflow pipe 85 is fixedly connected to a drain pipe 86, the end of the drain pipe 86 extends to the outside of the main floating ship 1, and the bottom end of the cylindrical shell 81 is fixedly connected to a conical container 83, and the bottom end of the conical container 83 is provided There is a sand discharge port 84, and the sand discharge port 84 is located above the front sediment collection section inside the main floating ship 1. The outer surface of the cylindrical shell 81 is fixedly connected to a plurality of legs 87, and the legs 87 are fixedly installed on the top of the bracket 11. The water-sand mixture enters along the tangential direction of the cylindrical shell 81 at a certain speed, and a strong rotating flow field is formed in the cylindrical shell 81, which can perform cyclone separation on the water-sand mixture, separate the heavier sediment particles and collect them in the front sediment collection section inside the main floating ship 1, and discharge the lighter water onto the river surface.

[0032] like Fig. 9 As shown, the liquid supply component 9 includes a pump 91 fixedly installed on the top of the bracket 11, a water inlet of the pump 91 is installed with a water suction pipe 92, and one end of the water suction pipe 92 is connected with the middle section to be treated inside the main floating ship 1, and a water outlet pipe 93 is installed at the water outlet of the pump 91, and one end of the water outlet pipe 93 is connected with the feeding pipe 82. Through the pump 91, the water suction pipe 92 and the water outlet pipe 93, the water-sand mixture is extracted from the middle section to be treated inside the main floating ship 1 and fed into the feeding pipe 82 of the cyclone separation component 8, so as to provide the water-sand mixture for the cyclone separation component 8 and ensure the continuous cyclone separation.

[0033] Working principle of the device: First, the main pontoon 1 and the auxiliary pontoon 2 move in the river under the push of the bottom propeller 3 and arrive at the predetermined area to be treated. At this time, the main pontoon 1 is close to one side of the river bank, and the auxiliary pontoon 2 is away from the main pontoon 1 and close to the other side of the river bank. When the auxiliary pontoon 2 is away from the main pontoon 1, the first motor 44 on the auxiliary pontoon 2 is started to drive the corresponding rotating shaft 42 to rotate and adjust the length of the steel cable 45. When the steel cable 45 is released, the auxiliary pontoon 2 can be smoothly moved to the other side of the river bank, opening up space for subsequent operations.

[0034] Next, the second motor 75 in the sand suction assembly 7 is operated to drive the hollow tube 72 to rotate and release the hose 76. At this time, under the action of the gravity of the sand suction head 77 itself, the released hose 76 is pulled to sink into the riverbed until the sand suction head 77 contacts the mud on the riverbed. At this point, the preparation process for the operation is completed. During the sinking or rising process of the sand suction head 77, due to the contact between the hose 76 and the pulley 57, the pulley 57 rotates under the action of friction. When the pulley 57 rotates, the winding roller 61 is driven to rotate through the extension shaft 56, and the limiting rope 64 on the winding roller 61 will follow the sinking or rising of the sand suction head 77 to achieve releasing or winding. Since the limiting rope 64 has a certain upward pulling force on the sand suction head 77, the sand suction head 77 can always be kept at a relatively fixed angle, thereby avoiding the situation that the sand suction head 77 rotates during the movement, thereby improving the stability of the operation of the sand suction head 77.

[0035] When sucking the riverbed sediment, the sand suction pump 710 is started, and the impeller in the pump starts to rotate at a high speed. The rotation of the impeller generates negative pressure in the pump, thereby forming a strong suction force. Since the sand suction head 77 is located in the riverbed, under the suction force generated by the sand suction pump 710, the water-sand mixture in the riverbed first enters the sand suction head 77, and then passes through the hose 76, the hollow tube 72, the sand suction pipe 711 in sequence, and finally outputs to the coarse filtering section at the rear of the main floating ship 1 through the water outlet of the sand suction pump 710 and the sand outlet pipe 713. Here, the water-sand mixture will flow to the to-be-treated section through the pores on the filter plate 12 for preliminary filtration. Some relatively large sediment particles that are easy to clog subsequent treatment equipment are isolated in the coarse filtering section by the filter plate 12, thereby reducing the possibility of hard impurities entering subsequent equipment, reducing the degree of wear of the equipment, and extending the service life of the equipment. At the same time, the subsequent separation burden of the cyclone separation component 8 is reduced, and the working efficiency is improved.

[0036] After that, the pump 91 in the liquid supply component 9 is started, and the water-sand mixture is extracted from the to-be-treated section through the water suction pipe 92, and then sent to the feeding pipe 82 of the cyclone separation component 8 through the water outlet pipe 93. The water-sand mixture enters along the tangential direction of the cylindrical shell 81 at a certain speed, and a strong rotating flow field is formed in the cylindrical shell 81. Due to the action of centrifugal force, the heavier sediment particles are thrown to the inner wall of the cylindrical shell 81 and move downward, and finally fall into the front sediment collection section inside the main floating ship 1 through the sand discharge port 84 of the conical container 83, while the lighter water forms an upward vortex, flows out from the overflow pipe 85, and is discharged to the river surface through the drainage pipe 86, thereby achieving the effect of circulation treatment.

[0037] In the process of sucking riverbed sediment, the two first motors 44 on the main pontoon 1 and the auxiliary pontoon 2 are controlled to operate, so as to drive the two shafts 42 to rotate synchronously. At the same time, the second motor 75 is controlled to operate so as to have the same direction of rotation as the first motor 44. When the shafts 42 on both sides rotate in one direction, the steel cable 45 on one side of the shaft 42 will be released and the shaft 42 on the other side will be retracted. At this time, the suspension assembly 5 will be driven to move horizontally on the river surface. At the same time, due to the operation of the second motor 75, the hose 76 is released or retracted, so that the hose 76 and the suspension assembly 5 move synchronously on the river surface, so that the sand suction head 77 can shuttle back and forth between the main pontoon 1 and the auxiliary pontoon 2 when sucking sediment, thereby ensuring the cleaning effect of the sediment at the bottom of the river.
