80results about How to "Reduce personal safety risks" patented technology

The present invention relates to the field of intelligent inspection technology, in particular to an intelligent inspection system for a photovoltaic power station drone, including: an impeller cover, an impeller, a damping shaft, an upper casing, a lower casing, a connecting seat, a bracket, a connecting arm, a fixing seat, Connecting frame, micro motor, camera, folding frame; the bottom side of the upper shell is provided with a lower shell, and the lower shell is connected with the upper shell through bolts; the left and right sides of the outer wall of the lower shell are provided with a damping shaft, and the damping The rotating shaft is connected with the lower shell through the support arm; a folding frame is arranged under the outer wall of the damping rotating shaft, and one end of the folding frame is connected with the damping rotating shaft through a movable connection; the other end of the folding frame is provided with an impeller, and the impeller passes through The impeller cover is connected with the folding frame. Through structural improvement, the present invention has the advantages of small inspection difficulty, high efficiency, low labor cost, and low personal safety risk, thereby effectively solving the problems and deficiencies in the prior art.

Disclosed are a building structure and a construction method. The building structure comprises upright columns, prefabricated plates or prefabricated frames and columnar connecting parts. Each prefabricated plate or prefabricated frame comprises reinforced beams or section crossbeams and embedded connecting parts, wherein the reinforced beams or section crossbeams are embedded in the prefabricated plates or prefabricated frames, and the embedded connecting parts are arranged at connecting joints for connecting the reinforced beams or section crossbeams; the columnar connecting parts are mounted at connecting joints of the prefabricated plates or prefabricated frames; the number of the columnar connecting parts is smaller than or equal to that of the embedded connecting parts; each embedded connecting part comprises a first positioning mechanism; each columnar connecting part comprises one to four second positioning mechanisms matching with the corresponding first positioning mechanisms in a one-to-one correspondence manner; and the first positioning mechanisms and the corresponding second positioning mechanisms are vertically connected in an inserted manner, and the columnar connecting parts are fixed with the one to four embedded connecting parts at the connecting joints. The building structure and the construction method have the advantages that various portions of the building structure can be mechanically assembled and disassembled, can be reused, and are convenient in assembly and disassembly, and the connecting joints are firm and reliable in connection and fine in load-carrying capability.

The invention relates to the technical field of aquaculture, in particular to a trawl net for double-surface spring-tooth benthonic shellfish which is a full symmetric structure. The structure is new, and the structure can normally work while any one surface touches the seabed, so the problem that the normal shellfish net cannot catch caused by that the abdominal net faces upside and the back net faces downside while operates in the large deep-water area, especially rational and stable catching efficiency of the trawl net on underwater posture is showed while the trawl net is used in the large deep-water areas and the heavy storm areas. The invention not only saves the work time and the energy consumption, but also reduces the personal safety risk during the work period, improves the safety coefficient of releasing net, and saves the energy consumption. The invention has important significance for upgrading the benthonic shellfish breeding equipment and has wide popularization and use values.
