This invention belongs to the field of prefabricated building technology and discloses a prefabricated ceiling and its installation method. A supporting component is provided between the keel component and the panel. The supporting component includes a hanger connecting the keel component and a supporting rod for connecting the panel. The panel has a bearing groove formed by bending at least two opposite sides. The bearing groove extends along the edge of the panel and has an open structure design at the corner of the panel to facilitate the lateral sliding or insertion of the supporting rod. This invention provides an independent supporting component composed of hangers and supporting rods between the keel component and the panel, so that the support of the decorative panel no longer depends on the continuous passage of the secondary keel. When the secondary keel path encounters electromechanical pipelines such as fire sprinkler pipes, it can be directly bypassed without on-site cutting; while the panel obtains effective support through adjustable supporting rods.

This utility model discloses an intelligent monitoring manhole cover for settlement, comprising a manhole cover body, a warning element within the manhole cover body, a rotating shaft within the manhole cover body, an actuating element fixed to the side of the rotating shaft, an end of the actuating element extending outward away from the rotating shaft, and a transmission element hinged to the top of the rotating shaft. The manhole cover body has an opening and a sealing element for closing the opening; the end of the sealing element away from the opening is hinged to the end of the transmission element away from the rotating shaft. A support element is also fixed within the manhole cover body, with an extension element inside and a telescopic spring sleeved on the outside. The warning element is fixed to the upper end of the extension element and abuts against the sealing element. This utility model connects the relatively stationary manhole cover groove and the movable manhole cover body through the actuating element, utilizing the difference in settlement displacement between the two to automatically trigger a mechanism. No power supply or sensors are required; when the manhole cover settles, a highly visible warning element immediately pops up, preventing pedestrians from falling, vehicles from bumping, or tires from bursting.

The utility model relates to an electric release door lock inner opening double-pull unlocking mechanism through transition piece drive relates to the field of automobile door lock, and the unlocking mode is as follows: when the door lock is in the armed state, first pull the inner opening pull rod rotates around the hole, sequentially drive the inner opening double-pull transition piece, the central control transmission transition rod, the central control transmission rod, the central control transmission gear, the double-pull transmission rod, the double-pull release transition rod and the inner opening transition rod movement, thereby realize the inner opening transition rod place and mechanical solution central control insurance of armed state, the second pull inner opening pull rod can directly rotate the electric opening release rod through the inner opening transition rod, the electric opening release rod rotates and promotes the outer opening release rod, and the outer opening release rod rotates and releases the ratchet pawl through the ratchet pawl release rod, and completes the unlocking. The utility model can realize the same inner opening double-pull unlocking with mechanical lock, and solves the technical defects that the existing electric opening lock system cannot mechanically remove the central control lock under the power-off working condition.

The invention provides a business processing method and system based on database data change driving, and the method comprises the steps: obtaining data change information in a database log through Debezium, and analyzing the data change information into a structured event message; adopting Kafka to carry out receiving, persistence processing and flow peak clipping processing on the event message; distributing the event message processed by the Kafka to a downstream service layer according to a preset configuration rule by adopting an intelligent router; and the downstream service layer receives the event message and carries out corresponding service processing.

This invention relates to the field of electromagnetic gun technology and discloses a multifunctional electromagnetic gun for firing tranquilizer darts, comprising a gun mount, an electromagnetic coil, a tranquilizer dart, and a propulsion assembly. The electromagnetic coil includes a first coil and a second coil fixedly connected to the top of the gun mount and horizontally arranged. The tranquilizer dart is installed inside the first coil, and the propulsion assembly slides through the second coil. The tranquilizer dart includes a hollow shell, a needle, a check plug, and a piston. The needle is fixedly connected to one end of the hollow shell, and the check plug is fixedly connected to the end away from the needle. The piston slides inside the hollow shell, and the piston and needle are filled with anesthetic. In this invention, the first and second coils, coaxially arranged and with the same magnetic direction, form a dual electromagnetic drive structure. After being energized, they can simultaneously generate electromagnetic thrust on the tranquilizer dart and the propulsion assembly, significantly increasing the initial velocity and kinetic energy of the tranquilizer dart and effectively extending the effective range of the device.
