Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of river ecological restoration, and particularly relates to a river ecological management and restoration process. BACKGROUND

[0002] The silt in the river is caused by natural phenomena such as precipitation, river erosion, etc. The soil on the river bank and in the river basin is eroded, and the silt formed by the siltation of the silt and the growth, reproduction and death of the aquatic plants in the river, the feces and carcasses of aquatic animals, etc. accumulate at the bottom of the river. The organic matter is decomposed by microorganisms, part of which becomes nutrient substances and participates in ecological circulation, and the other part is mixed with silt to form silt. The silt in the river continuously accumulates at the bottom of the river, the water section of the river is reduced, and the water depth is shallower. During the flood period, the river cannot accommodate the normal flow of flood, the water level rises rapidly, and the risk of flood is increased. The organic matter in the silt consumes oxygen in the water during the decomposition process, which reduces the dissolved oxygen content of the water and causes the aquatic organisms to die due to lack of oxygen.

[0003] Traditional river management will cause serious disturbance to the ecological system of the river. When the silt is transferred and repaired, the habitat of the aquatic plants and benthic animals at the bottom of the river is directly destroyed. The silt is stirred by the equipment, which may bury or injure the benthic organisms at the bottom of the river, resulting in a decrease in the number of the benthic organisms. At the same time, the root system of the aquatic plants is destroyed, which affects the growth and reproduction of the aquatic plants and further destroys the entire aquatic ecological chain. In order to protect the ecological environment in the river, people use to spray medicine into the river to improve the quality of the silt in the river. Although this method effectively protects the ecological environment in the river, the medicine can only be sprayed on the water surface, and the degradation process of the medicine is relatively long. During the degradation process of the medicine, the medicine is carried away by the water flow, which makes the treatment of the silt in the river unsatisfactory. When the silt is treated, the plants in the river are cut by a cutting cutter. A large amount of plants will cause blockage of the hose, so that the silt cannot be effectively pumped into the silt collection tank, which affects the efficiency of the silt treatment. After the silt is pumped into the silt collection tank through the hose, the pumping mechanism needs to stop pumping, the additive adding device is used to add additives into the collection tank, and then the additives are mixed. The working efficiency of the ecological management is greatly reduced. SUMMARY

[0004] The purpose of this invention is to provide a river ecological management and restoration process. In this structure, the screw conveyor is driven by a drive component to swing along the support shaft at a certain amplitude when extracting silt. This allows for the extraction and transmission of silt over a large area. During the swinging of the support frame, the silt is transferred through the inlet to two mixing chambers inside the housing via a transfer pipe. This effectively avoids the accumulation of large amounts of silt in the same chamber, which could lead to uneven mixing of the added chemicals. During stirring, the second drive motor drives the first lead screw to rotate, causing the first slide to move along the first guide rod, along with the first drive motor and the stirring shaft. During the movement of the first slide, the first toothed plate meshes with the gear, which drives the inner tank to rotate via the shaft. When the first circular hole on the inner tank coincides with the second circular hole on the outer tank, the chemicals are added to the silt in the mixing chamber. The stirring shaft achieves mixing between the chemicals and the silt, ensuring the treatment effect of the chemicals on the silt. This solves the problems mentioned in the background technology.

[0020] As a further technical scheme of the present application, the support frame, the mixing assembly and the driving assembly are all fixedly installed on the carrier frame.

[0021] Compared with the prior art, the present application has the following advantages:

[0022] 1. In use, the carrier frame is placed in the river channel, the connecting block is driven by the electric push cylinder installed in the support frame to insert one end of the suction hole of the screw conveyor into the sludge in the river channel, the sludge to be treated is conveyed to the inlet on one side of the box through the connecting pipe and the conveying pipe by the screw conveyor inside the screw conveyor, and in the sludge treatment of different river channels, the depth of the sludge can be adjusted by the electric push cylinder installed in the support frame to adjust the depth of the inserted end of the suction hole of the screw conveyor.

[0023] 2. In the process of extracting the sludge by the screw conveyor, the first connecting shaft is rotated by the stepping motor, at this time, the first cam on the first connecting shaft is in contact with the roller at the bottom of the first sliding rod, when the top of the first cam rotates downward, the first sliding rod moves downward along the C-shaped frame at the top of the fixed frame through the roller by the first cam, at the same time, the first bevel gear installed on the first connecting shaft drives the second bevel gear at the end of the second connecting shaft to rotate, the second bevel gear drives the second cam to cooperate with the roller at the bottom of the second sliding rod through the second connecting shaft, and the second sliding rod slides upward along the C-shaped frame by the upward rotation of the second cam.

[0024] 3. The first cam and the second cam are in opposite directions, so that the first sliding rod and the second sliding rod slide alternately upward and downward when the first sliding rod and the second sliding rod in the C-shaped frame are jacked, the first sliding rod moves upward at the same time, the second sliding block moves upward, the contact between the second sliding block and the support frame is realized, the support frame bottom rotates along the support shaft, so that the end of the screw conveyor with the suction hole swings to one side, at the same time, the second sliding rod drives the first inclined block to move downward under the action of the second cam, so as to avoid the interference caused by the swing of the support frame, and the same is true when the second sliding rod drives the first inclined block to slide upward, the first sliding rod drives the second inclined block to slide downward.

[0025] 4. In this invention, when the support frame drives the screw conveyor to swing left and right, the end of the conveying pipe away from the support frame swings left and right inside the feed inlet, thereby conveying the sludge to different mixing chambers. This effectively avoids the accumulation of large amounts of sludge, which could lead to unsatisfactory mixing effects when adding drugs. During mixing, the second drive motor drives the first lead screw to rotate, causing the first slide to drive the first drive motor and the stirring shaft to reciprocate along the first guide rod. During the sliding of the first slide, a first toothed plate is mounted on the first slide via a fixed block. This first toothed plate is located below the fixed frame, thus preventing interference during the sliding of the first slide. In this invention, during the movement of the first slide and the first toothed plate... The first toothed plate meshes with the gear at the bottom of the rotating shaft. The gear drives the inner tank to rotate inside the outer tank via the rotating shaft. When the first round hole at the bottom of the inner tank coincides with the second round hole at the bottom of the outer tank, the agent in the inner tank is added to the sludge in the mixing chamber. The agent improves the harmful components in the sludge. Depending on the improvement needs, the agent can be a flocculant, oxidant, or solidifier. At the same time, the first slide drives the stirring shaft to reciprocate, effectively achieving thorough mixing between the agent and the sludge. After mixing, the sludge in the two mixing chambers is effectively discharged back into the river through the first and second discharge ports, respectively. The addition of the agent improves the properties of the sludge in the river and improves the water quality. Attached Figure Description
