This invention relates to the field of bookshelf technology, and more specifically discloses an adjustable shelf spacing library book anti-tipping storage bookshelf, including a bookshelf component. The bookshelf component includes a bookshelf body, with T-shaped grooves on both side walls of the bookshelf body. The bookshelf body is divided into a book placement layer and an adjustable top layer. Multiple arrays of moving components are slidably connected between the T-shaped grooves. A detection box and a control unit are fixedly connected to the outer side wall of the moving components. A monitor is fixedly connected to the outer side of the top wall of the bookshelf body. This invention, by including the bookshelf component, moving components, and detection box, facilitates the setting of an adjustable top layer and adopts a mechanism where the movement of one layer drives the linkage of all upper layers. Combined with timed center of gravity monitoring, it ensures a safety margin when adjusting the shelf spacing, achieving the optimal center of gravity position. When the center of gravity is too high, the lower layers are appropriately reduced to decrease the safety margin of the lower layers, effectively preventing the bookshelf from tipping over due to imbalance of the center of gravity.

The application discloses a kind of air purifiers with whole house cruise function, it is related to air purifier technical field, including purifier main body and the cruise base being installed to its bottom;The purifier main body is sequentially distributed with fan cavity, purification cavity, drive cavity from top to bottom, the inside of the purification cavity is sequentially distributed with activated carbon filter screen, photocatalytic cylinder and multiple ultraviolet lamps from outside to inside;The photocatalytic cylinder is drivenly connected by with intermittent drive mechanism in the drive cavity, the intermittent drive mechanism drives the photocatalytic cylinder intermittent rotation around multiple ultraviolet lamps;The outside of the photocatalytic cylinder is provided with multiple brushes that are slid with it and adhere;The outside of the purifier main body is provided with protection mechanism, and the protection mechanism includes unfolded state and folded state.The application uses intermittent drive mechanism to cooperate brush, prolongs air reaction time while realizing the automatic dust removal of photocatalytic cylinder and effect.

The application relates to the technical field of building engineering monitoring, in particular to a building construction safety monitoring method and system based on sensors, which comprises the following steps: collecting real-time displacement monitoring data of each monitoring point of a building structure through a displacement sensor array, calculating the displacement value difference between each sensor node and its adjacent sensor node based on the real-time displacement monitoring data, and obtaining the displacement gradient value between the nodes; comparing the displacement gradient value between the nodes with a preset gradient threshold value, and activating the sensor array reconstruction mechanism when the displacement gradient value exceeds the preset gradient threshold value. In the monitoring process, the displacement gradient is used as a trigger signal to drive the idle nodes to automatically migrate to the high deformation gradient area, the dynamic matching of the sensor density and the deformation intensity is realized, the deformation capturing capability and the response speed of the monitoring area are improved, the corrected set is generated by fusing the strain and displacement data, the noise is filtered by using the time sequence correlation degree, the environmental interference is eliminated, and the stability of the monitoring data is ensured.

The utility model relates to the technical field of fermented bean curd, specifically relates to a multilayer fermented bean curd fermentation frame, including multigroup vertical interval arrangement's through -and -through tray, the inside lower side wall fixed limit strip for supporting embedded hole -like board of tray, the both sides of hole -like board are equipped with pull rope and is convenient for to extract, the rotating plate of rotating groove is fixed in the middle of tray one end, the rotating bearing installed in the groove is arranged on the outside of support column and forms the rotating pivot, need to operate when horizontally pulling tray, rotating bearing rotates along the support column and makes the layer to slide outward, through pull rope to take out hole -like board and its carried bean curd blank, complete detection or replacement operation in open space, after reset, hole -like board returns to limit strip fixed, multilayer tray keeps vertical ventilation state, the structure will traditional longitudinal operation change into horizontal operation, eliminate the need of interlayer reserved arm operating space, make interlayer distance need only satisfy the thickness of bean curd blank and bearing structure, significantly improve the stacking density and capacity in the same space.

The invention relates to multifunctional in-situ repair hydrogel based on a modified dermal matrix as well as a preparation method and application of the hydrogel. The hydrogel is formed by crosslinking a first polymer precursor and a second polymer precursor through dynamic covalent bonds of boric acid ester, the first polymer precursor is carboxymethyl chitosan grafted with a phenylboronic acid group and an epsilon-polylysine chain segment; the second polymer precursor is a soluble acellular dermal matrix which is grafted with a 3, 4-dihydroxyphenyl propionic acid group and is subjected to enzymolysis treatment. The hydrogel disclosed by the invention has good biocompatibility, moldability and potential self-healing capability.
