The invention relates to the technical field of the Internet of Things, in particular to a wrap-type easy-to-clean dust device controlled by the Internet of Things. The technical problem to be solved by the present invention is that the existing camera cleaning mechanism has limited cleaning area, is easy to block the field of view and is inconvenient for stable cleaning. In order to solve the above technical problems, the present invention provides a wrap-type easy-to-clean dust device based on the control of the Internet of Things, which includes an inclined strut of the mounting seat, and a fixed piece of the inclined strut is welded on the top of the inclined strut of the mounting seat. Both sides of the top of the fixed sheet tilting strut are respectively fixedly connected to both sides of the bottom of the side surface of the U-shaped tilting strut through the strut tilting strut, and one end of the U-shaped tilting strut is fixedly connected to a camera tilting strut . The tilting movable wrapping mechanism of the present invention can conveniently cover the camera or move it to a position away from the camera, so that the cleaning of the camera can be completed conveniently without affecting the monitoring field of view of the camera.

The invention discloses an intelligent detection system for a direct-current tubular bus. The intelligent detection system comprises a tubular bus, the tubular bus is sleeved with a first arc sleeve and a second arc sleeve, and the two opposite sides of the first arc sleeve and the second arc sleeve butt joint; clamping blocks are fixedly connected to the two sides of the top of the first arc sleeve and connected into clamping grooves formed in the two sides of the bottom of the second arc sleeve in a sleeved mode respectively, through grooves are formed in the inner walls of one sides of theclamping grooves, sliding grooves are formed in the tops and the bottoms of the inner walls of the through grooves, and the two sides of the inner walls of the sliding grooves are connected through first sliding rods. According to the intelligent detection system for the direct-current tubular bus, a detector is improved, and when two shifting rods are oppositely pushed, the shifting rods can drive two pressing plates to oppositely move through installing blocks, and therefore the two pressing plates can be separated; at this moment, the detector is conveniently taken out of installing grooves, and is put into the installing grooves, then the shifting rods are loosened, and under the effect of resilience force of clamping springs, the pressing plates can clamp the detector through rubber blankets.

The invention relates to the technical field of stationery, and particularly relates to a special wrapping sleeve for a round eraser for removing eraser crumbs and a using method. The special wrappingsleeve is formed by combining a round sleeve and a sealing cover, cylindrical cavities are formed in the upper side and the lower side of the interior of the round sleeve correspondingly, pistons aremovably sleeved with the cylindrical cavities, and one sides of the pistons are fixedly connected with one ends of universal driving shafts, the other ends of the two universal driving shafts penetrate through one side of the round sleeve and are fixedly connected with the upper end and the lower end of one side of the sealing cover, a hollow shaft is inserted into a bearing embedded in one sideof the inner wall of the round sleeve, a hollow sleeve is welded to one side of the bearing, one end of the hollow shaft penetrates through the hollow sleeve, and a gear is sleeved with the hollow shaft and located in the hollow sleeve. According to the special wrapping sleeve for the round eraser for removing the eraser crumbs and the using method, the eraser is partially exposed out of the roundsleeve and is directly pushed on the paper surface, at the moment, the eraser can rotate while erasing wrongly written characters, when the eraser rotates, the surface of the eraser can rub a wrapping piece, therefore, eraser crumb strips can be removed in time, and the defects caused by digging with hands and reusing are avoided.

The invention discloses a portable dual-purpose tongue depressing and scraping device for pediatric clinical use, which comprises a main body, a disposable tongue depressing cover and a disposable tongue scraping cover. Slidingly connected with a slider, the outer surface of the slider is provided with a connecting rod, a cross bar is provided between the connecting rods, and a handle is provided on the side surface of the cross bar. The size of the disposable tongue depressor is the same as that of the disposable tongue scraper The sizes are all matched with the main body, and the upper surface of the disposable tongue scraper is uniformly provided with bumps, and the upper surface of the main body is provided with an illuminating device. This portable dual-purpose device for tongue depressor and tongue scraping for clinical use in pediatrics uses disposable products to be socketed on the main body, which avoids cross-infection and also saves the trouble of cleaning and disinfection, improves hygiene, and is beneficial to children's health , and has rich functions, easy to observe, simple to operate, easy to use, and can meet different needs of use.
