The invention discloses an automatic fire extinguishing device suitable for a large high-rise building. The automatic fire extinguishing device comprises a fixed base fixedly arranged on the edge of aroof. A first motor is fixedly arranged in the upper end face of the fixed base, the upper end of the first motor is in power connection with a rotary arm, a lifting device is arranged at the right end of the rotary arm, a supporting block is arranged on the lower side of the lifting device, a storage cavity with a leftward opening is formed in the supporting block, an adsorption fixing device isarranged in the upper wall of the storage cavity, and a fire extinguishing device is arranged between the front wall and the rear wall of the storage cavity. The automatic fire extinguishing device can be used for firefighting work of floors exceeding the fire extinguishing height of a firefighting truck, under the condition that the building height of a city becomes higher and higher, due to thelimitation of current firefighting equipment, firefighting work at the high position cannot be completed from the ground, the device is mounted on the tops of the floors, the descending height can befreely controlled through a steel rope, then firefighting work of the different floors is completed, and the weakness of ground firefighting work is overcome.

The invention relates to a construction method for an integrated external wall masonry system, which includes the following construction steps: 1), prefabricating a precast concrete slab in a factory; 2), selecting a suitable spreader according to the component form and lifting height; 3), placing the precast concrete Lift the slab to the construction position; 4), stop the lowering of the precast concrete slab when it is 50cm away from the installation position, and check whether the front and back of the precast concrete slab are consistent with the drawings; 5), initially fix the position of the precast concrete slab according to the position of the embedded anchor bolt; 6 ), accurately adjust the position of the pre-embedded anchor bolt according to the control line, which coincides with the position of the measuring line; 7), the precast concrete slab is in place; the precast concrete slab is fixed by the fixing nut, so that the precast concrete slab is fixed on the column; 8), The reserved tie reinforcement of the prefabricated concrete slab and the outer wall of the block are built together; 9), the other side of the column is left with a joint with the outer wall of the block. The invention has the advantages of convenient construction, can reduce the thickness of the column-wrapped wallboard, reduce the risk of convex beams and convex columns, and the like.

The invention provides a self-adsorbable flexible battery and a preparation method thereof. Cyclodextrin is grafted as a main body to a gel electrolyte polymer monomer to form a polymer monomer matrix carrying main molecules; The monomer matrix is ​​in-situ polymerized with the ungrafted gel electrolyte polymer monomer to generate a gel electrolyte incorporating host molecules; adamantane or ferrocene is grafted as a guest to the binder polymer monomer The polymer monomer matrix carrying the guest molecules is formed on the polymer monomer matrix; the prepared polymer monomer matrix carrying the guest molecules is polymerized with the ungrafted binder polymer monomer to generate a binder incorporating the guest molecules. ; Add the binder doped with guest molecules into the positive and negative electrodes, and encapsulate it with the gel electrolyte doped with host molecules to form a self-adsorbing sandwich flexible battery. Compared with the existing flexible batteries, the flexibility is improved while extending the The service life of the battery makes up for the shortcomings of the existing flexible battery technology.

The invention provides a task dispatching method and system. Because of the adoption of message queues, tasks are processed by multiple servers simultaneously, the throughput capacity of the tasks isincreased, and meanwhile, the defect of serial processing of a single task by a single server is avoided; moreover, when the failure rate of task processing is increased, the message queues corresponding to different computer rooms can be switched, and the disaster tolerance capability of the task dispatching system is improved. The method comprises the steps that a saving module saves associationrelations between the message queues and an execution module; when a task needs to be processed, a generation module generates a task message of the task; according to a preset message storing rule,a determination module determines the message queue which the task message belongs to and then stores the task message into the message queue; the execution module monitors a notification message of the message queue which has the association relation with the execution module, obtains the task message in the message queue after the notification message is monitored and then sends the task messageto a vendor after the task message is obtained.
