Description

Technical Field

[0001] The present invention relates to the technical field of river management, and in particular to a floating object cleaning and collection device and method based on smart city river management. Background Art

[0002] Due to the slow flow of urban rivers, suitable water temperature and sufficient sunlight, duckweed and water plants grow rapidly in the river, making them one of the main floating objects in urban rivers. They not only affect the living space of aquatic organisms and pose a threat to their health, but also promote the growth of harmful microorganisms, further deteriorating the water quality of the river. Therefore, regularly cleaning and collecting duckweed and water plants floating objects in the river is an important measure to maintain the ecological environment of the river water.

[0003] A waterweed cleaning and collecting device for river management disclosed in the patent application with reference publication number CN222412931U is used in conjunction with a plug rod, a mounting block, a tooth plate, a gear, a transmission rod, a rotating block and a limit frame. After the waterweed in the collection box is cleaned, the bottom plate is disassembled for cleaning and maintenance to prevent the filter holes thereon from being clogged with fine waterweeds, which affects subsequent use. The structure is simple and easy to operate. The partition is used to protect the gear and the tooth plate to prevent the fallen waterweed from falling on the gear or the tooth plate and being entangled on the gear or the tooth plate, which affects its use or causes damage to the device. The above-mentioned prior art waterweed cleaning and collecting device for river management has the following defects in actual use: 1. After the waterweeds in the river are collected by the waterweed cleaning and collecting device for river management, the waterweeds are in a fluffy state and occupy a large storage space, so the waterweed cleaning and collecting device for river management needs to frequently dock to clean the stored waterweeds before it can clean the riverweeds again, resulting in low waterweed collection efficiency. In addition, a large amount of river water remains on the surface of the newly collected waterweeds, which significantly increases the deadweight of the waterweeds, thereby increasing the energy loss of the waterweed cleaning and collecting device for river management; 2. After being collected, aquatic plants are generally discarded as garbage. However, aquatic plants are high-quality fodder and fuel. Not only will this cause a waste of fodder, but directly discarding them will also increase the cost of later treating the aquatic plants as garbage.

[0004] Therefore, the present invention proposes a floating object cleaning and collection device and method based on smart city river management to solve the above problems. Summary of the invention

[0024] The embodiment of the present invention further provides a floating object cleaning and collection method based on smart city river management, which is used for a floating object cleaning and collection device based on smart city river management. The method comprises the following steps: Step 1: The electric boat 1 travels in the river of the smart city. The information processing component transmits the image information in the river to the terminal device, and the terminal device remotely controls the driving trajectory of the electric boat 1 through the feedback information. The specific process is as follows: a command is sent to the electric boat 1 by means of a terminal device, and the signal receiving antenna 3 drives according to the command after receiving the command, and the camera 4 sends the real-time captured image to the terminal device by wireless transmission, and the remote operator makes targeted processing based on the feedback image; After entering the water grass area, the water grass is guided by the two guide plates 6 and gathered in the middle position, so that the water grass is transported upward along the top of the conveyor belt 5. During the transportation process, part of the water on the surface of the water grass flows into the river channel through the gaps on the surface of the conveyor belt 5. After the water grass is transported to the highest position on the top of the conveyor belt 5, the water grass falls into the water grass crusher 71 located directly below under the action of gravity. The high-speed cutting knife in the water grass crusher 71 crushes the water grass into small particles, and falls into the No. 1 water grass dehydration forming component 72 and the No. 2 water grass dehydration forming component 73 through the discharge port at the bottom of the water grass crusher 71 respectively; The crushed waterweed particles slide into the filter cartridge 721 through the receiving hopper 725, and are pushed and squeezed by the dehydration auger 724. The remaining water in the waterweed particles flows into the gap between the outer cylinder 722 and the filter cartridge 721 through the filter holes on the surface of the filter cartridge 721, and is discharged into the river through the drainage pipe 723 to reduce the weight of the waterweed itself. The dehydrated waterweed particles are pushed into the inner heat preservation cylinder 728 by the dehydration auger 724. The electric heating wire 7210 heats the heat transfer oil in the heating gap after being energized. The heat is transferred to the surface of the waterweed particles inside the inner heat preservation cylinder 728. The waterweed particles are constantly turned over during the transportation process, and the heat is evenly transferred. After being heated at high temperature, the waterweed particles can kill the parasites and bacteria in the waterweed. After the water grass particles that have been heated and sterilized are pushed to the position of the forage forming mold 7212, the outlet space is sharply reduced, and the water grass is subjected to a large extrusion pressure at the position of the forage forming mold 7212. The water grass discharged from the forage forming mold 7212 is formed into strips due to the extrusion pressure. The rotating cutting blade 747 regularly cuts the strips of water grass that flow out of the forage forming mold 7212, so that the water grass is formed into particles of the same specification. The cut water grass particles slide along the inner wall of the storage hopper 1 751 to the storage hopper 2 753 for storage. After the storage hopper 2 753 is full, the storage hopper 2 753 can be separated from the storage hopper 1 751, and the water grass particles in the storage hopper 2 753 can be taken out and used as livestock feed or as fuel after drying; Step 2: The bottom end of the conveyor belt 5 is located below the water surface, and the two guide plates 6 gather the waterweeds on both sides to the middle position. The waterweeds are gradually collected on the top of the conveyor belt 5 as it runs, and are transported to the direction of the waterweed processing mechanism 7; Step three, the water grass transported by the conveyor belt 5 falls into the water grass crusher 71 under the action of its own gravity, and is crushed into small particles by the water grass crusher 71. The small particles of water grass enter the No. 1 water grass dehydration and molding component 72 and the No. 2 water grass dehydration and molding component 73, and are squeezed and dehydrated, and then are heated and sterilized and compressed to shape. The shaped water grass is cut into water grass particles of the same specifications and with some water to form livestock feed or fuel.
