On one hand, the algae breeding reduces the transparency of the water body, so that sunlight is difficult to penetrate through a permeable layer, the photosynthesis of plants in water is influenced, the supersaturated state of dissolved oxygen is possibly caused, aquatic animals are harmful, and a large amount of fishes die. On the other hand, harmful gases generated by the decomposition of organic substances accumulated on the bottom layer under anaerobic conditions and biological toxins generated by some plankton can also damage fishes; in addition, secondary substances formed by mass propagation of algae cause odor in water, increase the corrosivity of the water, and easily cause 'yellow water' in a pipe network under the condition of high water temperature in summer.
For major water transfer engineering carried out by adopting a channel mode, the quality of a water body is seriously influenced by the breeding of a large amount of underwater algae on the side slope of the channel, the algae in the water body can cause the water body to be fishy, green and black, the odor of most lakes and ponds is caused by substances such as hydrogen sulfide, sulfur, ammonia and the like generated by the death of algae and the oxygen deficiency of the water body, the dead algae are deposited on the side slope to seriously influence the quality of the water body, and more seriously, harmful substances such as algae toxin and the like can be generated to impact the treatment process of water plants along the line, so that the water supply cost is increased. Therefore, the method has the advantages of clearing the underwater long algae on the side slope, improving the water body conveying quality, reducing the treatment difficulty of the water plant, becoming a technical problem which needs to be solved urgently, and having important ecological and environmental significance.
At present, in the algae removal technology at home and abroad, in order to avoid the problem of secondary pollution to water quality, physical removal methods are usually adopted, and the methods mainly comprise manual cleaning, algae harvesting ship cleaning and the like. The manual cleaning is adopted, so that the labor intensity is high, the efficiency is low, and a large amount of dirt is diffused into water to cause secondary pollution. The algae harvesting boat has wide application and obvious effect, and can directly remove the algae in the water body. However, the existing algae harvesting ship can be used in water with flat terrain, and algae on the channel side slope cannot be removed.

After the working angles of the algae conveying mechanism 6 and the cutting knife assembly 7 are adjusted, a propelling motor and a motor reducer 23 are started, the propelling motor drives an impeller 10 to rotate at a high speed through a first chain transmission mechanism to push the ship body 1 to move forwards, the driving direction of the ship body 1 is adjusted through a steering control rod 12 in the moving process of the ship body 1, a guide wheel 32 is always kept in rolling contact with a channel side slope 31 in the algae harvesting operation process, meanwhile, the motor reducer 23 drives a driving roller to rotate through a second chain transmission mechanism, the driving roller drives a driven roller to rotate through two chains 24, a connecting rod 25 between the two chains 24 and a conveyer net move from front to back, the driven roller drives a movable knife part to reciprocate from left to right through a third chain transmission mechanism, algae growing on the side slope 31 are harvested through the reciprocating motion from left to right in the forward process of the ship body 1, the harvested algae move backwards to the moving conveyer net and are conveyed backwards through the conveyer net, and finally automatically fall onto the ship body 1 at the rear side of the driving roller.
The propeller 2 is used as power for advancing the hull 1, and the steering lever 12 is operated to rotate the impeller 10 in the direction to steer the entire hull 1. The top of the impeller 10 is provided with a cover 35 which can prevent the impeller 10 from generating splash upwards when rotating.
The invention adjusts the inclination angle of the mounting rack 4 by manually operating the worm screw lifter 14, so that the plane of the mounting rack 4 is parallel to the channel side slope 31, thereby adapting to the slope 31 of different channels or different river sections. The inclination angle of the algae conveying mechanism 6 is supported and positioned by adopting the two supporting and adjusting rod pieces 8, so that a small gap is kept between the cutting knife assembly 7 and the channel side slope 31, and the cutting knife assembly 7 can harvest algae more thoroughly. The cutter assembly 7 adopts a cutter similar to a wheat combine harvester, and comprises a fixed cutter part and a movable cutter part, wherein the movable cutter part moves left and right on the surface of the fixed cutter part in a reciprocating manner to cut algae.
The front side of the support adjusting rod 8 is provided with a plurality of positioning slots 28 along the height direction, so that after the support wheel 33 is contacted with the channel side slope 31, the positioning pin 29 can be clamped into one corresponding positioning slot 28, and the support rod and the material guide baffle 21 are fastened and connected into a whole through a locking nut.
After the harvested algae fall onto the ship body 1, the algae can be adhered to the conveying net, the cleaning roller brush is driven to rotate by the cleaning motor, the surface of the conveying net which rotates to the lower half is cleaned, and therefore the phenomenon that the algae are immersed into water along with the conveying net to affect water quality can be avoided.
Because the conveying net and the cutting knife assembly 7 are high at the left and low at the right, the harvested algae slides off at the right side of the cutting knife assembly 7, and therefore, the front end of the guide baffle 21 at the right side extends forwards to the right side of the cutting knife assembly 7, and the harvested algae can be prevented from sliding off to the right.
A spring can be arranged between the supporting wheel 33 and the conveying frame 19, after the supporting wheel 33 is contacted with the channel side slope 31, the clearance between the cutting knife assembly 7 and the surface of the channel side slope 31 can be adjusted through the clamping matching of the positioning pin shaft 29 and different positioning clamping grooves 28, even the bottom surface of the fixed knife part can be directly in sliding contact with the channel side slope 31, and after the movable knife part harvests algae, the fixed knife part can further thoroughly remove the root of the algae on the side slope 31.
The ship body 1 of the invention adopts a flat plate type structure, the left side and the right side are parallel to the channel side slope 31, the ship body can more easily guide when moving along the channel side slope 31, and the ship body has good stability.
The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
