Description

Technical Field

[0001] The present invention specifically relates to the technical field of river ecological restoration, and specifically is a river ecological management and restoration process. Background Art

[0002] The silt in the river channel is caused by natural phenomena such as rainfall, river scouring, etc., which will cause the soil on the river bank and in the basin to be eroded. The washed-down soil flows into the river channel with the water flow and gradually settles to form silt. The growth, reproduction and death of aquatic plants in the river channel will produce a large amount of residues. The feces and corpses of aquatic animals will also accumulate at the bottom of the river channel. These organic substances will decompose under the action of microorganisms. Some of them will become nutrients and re-participate in the ecological cycle, and the other part will be mixed with sediment to form silt. The silt inside the river channel will continue to accumulate at the bottom of the river channel, and the water section of the river channel will decrease and the water depth will become shallower. During the flood period, the river channel cannot accommodate the flood of normal flow, and the water level will rise rapidly, increasing the risk of flooding. The organic matter in the silt will consume oxygen in the water during the decomposition process, resulting in a decrease in the dissolved oxygen content of the water body, causing the death of aquatic organisms due to lack of oxygen.

[0003] Traditional river management will cause serious interference to the river ecosystem. When sludge is transferred and repaired, it will directly destroy the habitats of aquatic plants and benthic animals at the bottom of the river. The stirring of sludge by equipment may bury or injure benthic organisms at the bottom of the river, resulting in a decrease in their number. At the same time, the root system of aquatic plants is destroyed, affecting their growth and reproduction, and thus destroying the entire aquatic ecological chain. Now, in order to ensure the ecological environment in the river, people adopt the method of spraying drugs into the river to improve the quality of sludge in the river. Although this effectively protects the ecological environment in the river, the drugs can only be sprayed on the water surface, so the process of waiting for the degradation of drugs is long. During the degradation of drugs, along with the water flow, the drugs are not ideal for the treatment of sludge in the river.

[0004] In the existing treatment of silt, the plants in the river channel are first cut by a cutting disc, so a large number of plants will cause clogging of the hose, so that the silt cannot be effectively pumped into the silt collection tank, affecting the efficiency of silt treatment; after the silt is pumped into the silt collection tank through the hose, the extraction mechanism needs to stop extracting, and then add additives into the collection tank through the additive dosing device, and then stir and mix, which greatly reduces the work efficiency in ecological treatment. Summary of the invention

[0005] The purpose of the present invention is to provide a river ecological management and restoration process. In this structure, the driving component is driven to realize the spiral conveyor to swing a certain amplitude along the supporting shaft when extracting the sludge, so that the sludge of a larger area can be extracted and transmitted. During the swinging of the support frame, the sludge is transmitted to the two mixing chambers inside the box body through the feeding port through the transmission pipe, so as to effectively avoid the accumulation of a large amount of sludge in the same chamber, so that the added medicine is mixed unevenly. During stirring, the first screw is driven to rotate by the second driving motor, so that the first slide drives the first driving motor and the stirring shaft to move along the first guide rod. During the movement of the first slide, the first tooth plate is meshed with the gear, and the gear drives the inner tank to rotate through the shaft.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When the present invention is used, the carrier is placed in the river channel, and the electric push cylinder installed inside the support frame drives the connecting block to insert one end of the suction hole on the screw conveyor into the silt in the river channel. The dragon roller inside the screw conveyor transmits the silt to be treated through the connecting pipe and the transmission pipe to the feed port on one side of the box body. When treating silt in different river channels, the electric push cylinder installed inside the support frame can realize the insertion depth of one end of the suction hole of the screw conveyor according to the depth of the silt;

[0024] 2. In the process of the screw conveyor extracting sludge, the stepper motor drives the first connecting shaft to rotate. At this time, the first cam on the first connecting shaft fits with the roller at the bottom of the first slide bar.

The second bevel gear drives the second cam through the second connecting shaft to cooperate with the roller at the bottom of the second slide bar. The second cam rotates upward to realize the upward sliding of the second slide bar along the C-shaped frame.

[0025] 3. In the present invention, the first cam and the second cam are in opposite directions, so that when the first slide bar and the second slide bar inside the C-shaped frame are pushed up, the first slide bar and the second slide bar slide up and down alternately, and when the first slide bar moves upward, it also drives the second inclined block to move upward, so as to achieve contact between the second inclined block and the support frame, and the bottom of the support frame rotates along the support shaft, so as to achieve the end of the screw conveyor with the suction hole being swung to one side, and at the same time, the second slide bar drives the first inclined block to move downward under the action of the second cam, so as to avoid interference with the swing of the support frame. Similarly, when the second slide bar drives the first inclined block to slide upward, the first slide bar drives the second inclined block to slide downward;

[0026] 4. In the present invention, when the support frame drives the spiral conveyor to swing left and right, the end of the conveying pipe away from the support frame swings left and right inside the feed port, so as to realize the transmission of sludge to different mixing chambers, which effectively avoids the accumulation of a large amount of sludge and causes the unsatisfactory stirring effect of the drug adding clamp. When stirring, the first screw rod is driven to rotate by the second driving motor, so that the first slide drives the first driving motor and the stirring shaft to reciprocate along the first guide rod. During the sliding process of the first slide, a first tooth plate is installed on the first slide through a fixed block, and the first tooth plate is located below the fixed frame, so that no interference will be caused during the sliding process of the first slide;

[0027] 5. In the present invention, during the process of the first slide driving the first tooth plate to move, the first tooth plate meshes with the gear at the bottom of the rotating shaft, and the gear drives the inner tank to rotate inside the outer tank through the rotating shaft. When the first circular hole opened at the bottom of the inner tank coincides with the second circular hole opened at the bottom of the outer tank, the medicine in the inner tank is added to the sludge in the mixing chamber, and the harmful components in the sludge are improved through the medicine. According to the needs of improvement, the medicine can be selected from flocculants, oxidants or curing agents, etc. At the same time, the first slide drives the stirring shaft to stir reciprocally, and effectively realizes sufficient stirring and mixing between the medicine and the sludge. After the stirring is completed, the sludge in the two mixing chambers is effectively discharged back to the river channel through the first discharge port and the second discharge port respectively. Through the addition of medicine, the properties of the sludge in the river channel are improved and the improvement of the water quality in the river channel is achieved.

During the rotation of the inner tank 60, when the second circular hole 64 and the first circular hole 65 coincide, the added medicine is sprinkled on the sludge in the mixing chamber, and then the stirring shaft 511 is driven by the first drive motor 54 to achieve stirring and mixing between the sludge and the medicine;

[0066] S4, the sludge after the medicine is added into the two mixing chambers is effectively discharged through the first discharge port 57 and the second discharge port 58 installed on the box body 50;

[0067] By adopting the above technical scheme, when the first slide 53 drives the first tooth plate 510 to move, the first tooth plate 510 meshes with the gear 63 at the bottom of the rotating shaft 62, and the gear 63 drives the inner tank 60 to rotate inside the outer tank 61 through the rotating shaft 62. When the first circular hole 65 opened at the bottom of the inner tank 60 coincides with the second circular hole 64 opened at the bottom of the outer tank 61, the medicine in the inner tank 60 is added to the sludge in the mixing chamber, and the harmful components in the sludge are improved by the medicine. According to the needs of improvement, the medicine can be selected from flocculants, oxidants or curing agents, etc. At the same time, the first slide 53 drives the stirring shaft 511 to stir reciprocally, effectively realizing sufficient stirring and mixing between the medicine and the sludge. After the stirring is completed, the sludge in the two mixing chambers is effectively discharged back to the river channel through the first discharge port 57 and the second discharge port 58 respectively. By adding the medicine, the properties of the sludge in the river channel are improved and the improvement of the water quality in the river channel is achieved.

[0068] The working principle of the present invention is as follows: when in use, the carrier 1 is placed in the river channel, and the electric push cylinder 24 installed inside the support frame 22 drives the connecting block 28 to insert one end of the suction hole 21 on the screw conveyor 20 into the silt in the river channel, and the silt to be treated is transmitted to the feed port 51 on one side of the box body 50 through the connecting pipe 25 and the transmission pipe 26 by the dragon roller inside the screw conveyor 20. When treating silt in different river channels, the depth of insertion of one end of the suction hole 21 of the screw conveyor 20 can be achieved according to the depth of the silt through the electric push cylinder 24 installed inside the support frame 22;

[0069] During the process of the screw conveyor 20 extracting the sludge, the first connecting shaft 712 is driven to rotate by the stepper motor 72. At this time, the first cam 73 on the first connecting shaft 712 is fitted with the roller 78 at the bottom of the first slide bar 74. When the top of the first cam 73 rotates downward, the first cam 73 realizes the downward movement of the first slide bar 74 along the C-shaped frame at the top of the fixed frame 70 through the roller 78. At the same time, the first bevel gear 79 installed on the first connecting shaft 712 drives the second bevel gear 710 at the end of the second connecting shaft 713 to rotate. The second bevel gear 710 drives the second cam 711 through the second connecting shaft 713 to cooperate with the roller 78 at the bottom of the second slide bar 75. The second cam 711 rotates upward to realize the second slide bar 75 sliding upward along the C-shaped frame.

[0070] The first cam 73 and the second cam 711 are in opposite directions. In this way, when the first slide bar 74 and the second slide bar 75 inside the C-shaped frame are pushed up, the first slide bar 74 and the second slide bar 75 slide up and down alternately. When the first slide bar 74 moves upward, it also drives the second inclined block 77 to move upward to achieve contact between the second inclined block 77 and the support frame 22. The bottom of the support frame 22 rotates along the support shaft 4, so that the end of the screw conveyor 20 with the suction hole 21 is swung to one side. At the same time, the second slide bar 75 drives the first inclined block 76 to move downward under the action of the second cam 711 to avoid interference with the swing of the support frame 22. Similarly, when the second slide bar 75 drives the first inclined block 76 to slide upward, the first slide bar 74 drives the second inclined block 77 to slide downward.

[0071] When the support frame 22 drives the screw conveyor 20 to swing left and right, the end of the transmission pipe 26 away from the support frame 22 swings left and right inside the feed port 51, so as to realize the transmission of sludge to different mixing chambers, which effectively avoids the accumulation of a large amount of sludge and causes the unsatisfactory stirring effect of the drug addition clamp. When stirring, the first screw rod 52 is driven to rotate by the second drive motor 59, so that the first slide 53 drives the first drive motor 54 and the stirring shaft 511 to reciprocate along the first guide rod 55. During the sliding process of the first slide 53, a first tooth plate 510 is installed on the first slide 53 through a fixed block 512, and the first tooth plate 510 is located below the fixed frame 56, so that during the sliding process of the first slide 53, no interference will be caused;

[0072] When the first slide 53 drives the first tooth plate 510 to move, the first tooth plate 510 meshes with the gear 63 at the bottom of the rotating shaft 62, and the gear 63 drives the inner tank 60 to rotate inside the outer tank 61 through the rotating shaft 62. When the first circular hole 65 opened at the bottom of the inner tank 60 coincides with the second circular hole 64 opened at the bottom of the outer tank 61, the medicine in the inner tank 60 is added to the sludge in the mixing chamber, and the harmful components in the sludge are improved by the medicine. According to the needs of improvement, the medicine can be selected from flocculants, oxidants or curing agents, etc. At the same time, the first slide 53 drives the stirring shaft 511 to stir reciprocally, effectively realizing sufficient stirring and mixing between the medicine and the sludge. After the stirring is completed, the sludge in the two mixing chambers is effectively discharged back to the river channel through the first discharge port 57 and the second discharge port 58 respectively. By adding the medicine, the properties of the sludge in the river channel are improved and the water quality can be improved.
