The invention discloses a mobile adsorption device used under a high-flow-velocity water area. The adsorption module is fixedly installed in the middle of the fluid guiding module, the rolling contact module is fixedly connected to the bottom of the fluid guiding module, and swirl vanes in the adsorption module are used for guiding water flow to flow to form high-speed swirl and performing underwater adsorption on a wall surface to be adsorbed through pressure difference caused by the swirl. When the mobile adsorption device is adsorbed on a to-be-adsorbed wall surface, the rolling contact module is attached to the to-be-adsorbed wall surface in a rolling manner, and a flow guide area is arranged in the fluid guide module and is used for counteracting external water flow and maintaining the stability of a rotational flow field generated by the rotational flow blades in a high-flow-speed water area; and therefore, stable adsorption of the to-be-adsorbed wall surface by the movable adsorption device is realized. The device is simple in structure, convenient to install, high in durability, particularly suitable for rivers, lakes and coastal areas with high water flow speed, and capable of generating enough suction force in large-flow-speed water areas.

The utility model discloses sharpening equipment for bamboo chopstick processing, which relates to the technical field of bamboo chopstick processing, and adopts the technical scheme that the sharpening equipment comprises a processing table, a supporting block fixedly connected to the top of the processing table, a motor I fixedly connected to one side of the supporting block, a rotating shaft I fixedly connected to an output shaft of the motor I, and the rotating shaft I penetrates through the supporting block; a polishing block fixedly sleeves outside one end of the rotating shaft I; the bamboo chopstick polishing device has the advantages that the distance between the two threaded blocks can be reduced through rotation of the two-way threaded rod, so that a bamboo chopstick body can be clamped, then the shell can move downwards through work of the electric push rod, and the bamboo chopstick body can be polished through the shell. The bamboo chopsticks can be sharpened, the bamboo chopsticks do not need to be manually held by hands during sharpening, the contact time of workers and equipment can be shortened, people are prevented from being hurt by the machine, and the safety coefficient is high.

The utility model provides a kind of cleaning accessory and scraping strip component with scraping strip component, it includes the accessory seat with air inlet and dust suction chamber and can move on a plane, and the scraping strip component is arranged in accessory seat bottom and located dust suction chamber one side, wherein the scraping strip component includes scraping strip base, a plurality of first scraping strip piece located scraping strip base one side and along the length direction interval arrangement of scraping strip base, and a plurality of second scraping strip piece located scraping strip base other side and along the length direction interval arrangement of scraping strip base, wherein the second scraping strip piece at least partially exists two position changes: wherein when first position, second scraping strip piece is close to first scraping strip piece;While in second position, second scraping strip piece is then away from first scraping strip piece.The utility model advantage is: through single movement, ground cleaning processing can be realized, both can guarantee the cleaning of large particle garbage, also can guarantee enough suction, save cleaning time simultaneously, improve efficiency.
