Description

TECHNICAL FIELD

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

[0002] Dredging is an important and basic technical means in river ecological restoration, and its core role is to directly improve the physical environment of the river by removing the long-term accumulated silt in the river, and to create necessary conditions for subsequent ecological restoration.

[0003] After the hardening treatment of the river, thick silt is accumulated on the river bottom over the years, and the texture of the silt will also harden from top to bottom. River bottom vegetation with river purification effect will be formed on the surface of the silt. These river bottom vegetation may also be planted during water body improvement construction. During the silt cleaning process, these vegetation cannot be damaged to avoid affecting the water purification effect.

[0004] Chinese patent (CN201811457183.4) discloses a caterpillar chassis cutter suction dredging robot with self-correction function, which can realize harmless continuous movement and rapid dredging underwater, and has self-correction function of travel trajectory, so that it can travel straight. The dredging robot comprises a platform frame, a caterpillar chassis, a silt suction mechanism, a dredging mechanism, an anti-collision guide device, a self-correction unit, a control unit and a vision unit arranged on the platform frame.

[0005] Chinese patent (CN202011135721.5) discloses a sludge cleaning equipment capable of protecting river bottom vegetation from damage, which comprises a support pulling frame, a power driving assembly, a speed reduction driving assembly, a water grass vegetation folding assembly and the like. The support pulling frame is provided with a power driving assembly at the top, the power driving assembly is connected with a speed reduction driving assembly, the speed reduction driving assembly is arranged on the support pulling frame, and the support pulling frame is provided with a water grass vegetation folding assembly on both sides of the lower part. Through the speed reduction driving assembly, the sludge digging frame can dig sludge at a faster speed, and multi-stage speed reduction transmission is realized.

[0006] At present, the existing dredging robot swing type dredging operation has unified dredging parameters, which makes the multi-level silt cleaning effect poor. After the silt is dredged, the river bottom vegetation on the upper layer will collapse downward to cause the root stem to separate from the soil. Although the water grass vegetation folding assembly can fold the water grass to one side to avoid being damaged by dredging, the river bottom vegetation after the root stem separation needs a long period of time to fall on the new silt accumulation layer and take root, which affects the water purification effect and purification efficiency of the river bottom vegetation. SUMMARY

[0007] The present application aims to solve the above-mentioned problems and provides a river ecological restoration device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a river ecological restoration device, comprising:

[0009] Tracked vehicle base;

[0010] A fixed cover is located at the front end of the tracked vehicle base, and the fixed cover is slidably connected to the fixed cover.

[0011] The first electric cylinder is fixedly connected to the tracked vehicle base, and the telescopic end of the first electric cylinder is connected to and drives the fixed cover.

[0012] Two-stage crushing mechanisms are symmetrically arranged and mounted on the fixed cover;

[0013] A support plate is fixedly connected to the top of the tracked vehicle base. A sedimentation groove is provided on the top surface of the support plate, and the sedimentation groove extends to the rear end of the support plate.

[0014] A compression mechanism is mounted on the support plate and extends into the sedimentation tank;

[0015] A slurry pump is fixedly connected to the bottom of the tracked vehicle base, and the slurry pump is connected to the fixed cover via a hose;

[0016] A shovel plate is located above the support plate and is slidably connected to the support plate;

[0017] The second electric cylinder is fixedly connected to the support plate, and the telescopic end of the second electric cylinder is connected to and drives the shovel plate;

[0018] A waterproof lithium battery pack is fixedly connected to the base of the tracked vehicle.

[0019] The controller is fixedly connected to the tracked vehicle base and is electrically connected to the waterproof lithium battery pack, the tracked vehicle base, the first electric cylinder, the grading and crushing mechanism, the compression mechanism, the slurry pump, and the second electric cylinder.

[0020] As a further description of the above technical solution:

[0021] The tracked vehicle base is provided with multiple first guide posts, the fixed cover is slidably connected to the multiple first guide posts, and the shovel plate is provided with multiple second guide posts, which are slidably connected to the support plate.

[0022] As a further description of the above technical solution:

[0023] The grading and crushing mechanism includes a support roller, a first rotary motor, multiple augers, and multiple second rotary motors. The support roller is mounted on the fixed cover via bearing seats. The first rotary motor is fixedly connected to the fixed cover, and its output end is connected to and drives the support roller. The multiple augers are mounted on the support roller via bearing seats and are arranged in a circular array along the axis of the support roller. The multiple second rotary motors are fixedly connected to the support roller, and each of the multiple second rotary motors corresponds to one of the multiple augers. The output end of each second rotary motor is connected to and drives the auger. The spiral specifications of each auger are different.

[0024] As a further description of the above technical solution:

[0025] The compression mechanism includes a flat pressure plate, a third electric cylinder, a filter screen plate, and a fourth electric cylinder. The flat pressure plate is slidably connected to the sediment accumulation groove. The third electric cylinder is fixedly connected to the support plate, and its telescopic end is connected to and drives the flat pressure plate. The filter screen plate is slidably connected to the support plate and blocks the rear end of the sediment accumulation groove. The fourth electric cylinder is fixedly connected to the tracked vehicle base, and its telescopic end is connected to and drives the filter screen plate.

[0026] As a further description of the above technical solution:

[0027] The top of the shovel plate is provided with multiple parallel guide grids, which extend above the silt accumulation trough.

[0028] As a further description of the above technical solution:

[0029] The width of the flat plate and the width of the filter screen are both the same as the width of the sedimentation tank.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] 1. In this invention, the height of the shovel is adjusted by extending and retracting the second electric cylinder. When the tracked vehicle base moves, the shovel inserts into the uppermost layer of silt to separate the riverbed vegetation. The height of the fixing cover is adjusted by extending and retracting the first electric cylinder. The graded crushing mechanism crushes the silt of different hardness and then pumps it out through the slurry pump, resulting in a good cleaning effect on the deep silt layer. The silt layer below the riverbed vegetation collapses, and the roots and stems of the riverbed vegetation and a small amount of silt from the upper layer enter the silt accumulation trough. The compression mechanism compacts the silt onto the roots and stems of the riverbed vegetation, so that the riverbed vegetation can take root as soon as it is thrown into the water, which greatly improves the water purification effect and purification efficiency of the riverbed vegetation.

[0032] 2. In this invention, the spiral specifications of each of the augers are different. The first rotating motor drives the support roller to rotate, and the rotation of the support roller switches the position of the auger, so that different augers are used for silt with different hardness layers. The second rotating motor drives the auger to rotate, and the rotation of the auger stirs the silt layer, so that the silt is diluted and mixed with the river water and then pumped out by the slurry pump, resulting in a good silt cleaning effect.

[0033] 3. In this invention, the third electric cylinder extends to drive the flat pressure plate to slide in the siltation trough. The flat pressure plate pushes the silt and riverbed vegetation roots to move in the siltation trough. The filter screen has the function of filtering water and compacts the silt onto the riverbed vegetation roots. The fourth electric cylinder retracts to remove its obstruction in the siltation trough. The riverbed vegetation with compacted silt is pushed back into the river water, so that the riverbed vegetation can have a rooting environment as soon as it is thrown into the water, which greatly improves the water purification effect and purification efficiency of the riverbed vegetation.

The tracked vehicle base 1 is placed on the hardened layer, and a camera is installed on the tracked vehicle base 1 to monitor the underwater conditions. Based on the position of the riverbed vegetation observed by the camera, the height of the shovel 9 is adjusted by extending and retracting the second electric cylinder 10. Under the control of the controller 12, the tracked vehicle base 1 moves forward. As the tracked vehicle base 1 moves, the shovel 9 inserts into the uppermost layer of silt to separate the riverbed vegetation. Second, the first rotary motor 42 rotates, driving the support roller 41 to rotate. The rotation of the support roller 41 switches the position of the auger 43, allowing different augers 43 to be used for different hardness layers of silt. The second rotary motor... The motor 44 rotates, driving the auger 43 to rotate. The auger 43 agitates the silt layer, diluting and mixing the silt with the river water before it is pumped out by the slurry pump 8, resulting in a good silt removal effect. Next, the third electric cylinder 72 extends, driving the flat pressure plate 71 to slide in the silt accumulation trough 6. The flat pressure plate 71 pushes the silt and riverbed vegetation roots within the silt accumulation trough 6. The filter screen 73 has a water filtration function, compacting the silt onto the riverbed vegetation roots. The fourth electric cylinder 74 retracts, removing its obstruction within the silt accumulation trough 6. The compacted riverbed vegetation is then pushed back into the river water, providing a rooting environment for the riverbed vegetation. Finally, the above operations are repeated to dredge the riverbed, restoring the river's ecology.
