The invention relates to the field of hooks, in particular to an anti-dropping device for a hook which is convenient for installation and disassembly. Each triangular support plate of the present invention is composed of a short board and a long board, and the angle between the short board and the long board ranges from 50 degrees to 70 degrees; the bottoms of the two short boards are connected by a bayonet, and the bottoms of the two long boards pass through Pin connection; the intersection of the short and long plates of the two triangular support plates is connected by a pin. The device of the invention can effectively improve the safety of the hoisting operation, and can satisfy the long-term high-intensity use, is easy to recover after the device fails, and can effectively reduce the labor intensity of the operators.

The invention discloses a solar steam heating method and a self-contained heat source system for implementing the same. The self-contained heat source system comprises a solar collecting unit, an energy storage tank and a steam heating device which are sequentially connected with one another. The solar steam heating method and the self-contained heat source system have the advantages that steps of the method are simple, the method is easy to implement and low in cost, and solar energy can be collected, stored and utilized at terminals and is optimally integrated, so that heat energy is utilized to the greatest extent, the bottleneck in the aspect of civil use of intermediate-temperature solar energy is broken through, and rural solar utilization markets are broadened; the self-contained heat source system is smart and reasonable in structural design, the solar energy can be sufficiently utilized to supply a heat source quickly and continuously, materials can be quickly heated as needed, the self-contained heat source system is additionally provided with an electric auxiliary heating device, and the solar collecting unit and the electric auxiliary heating device are smartly and organically combined with each other, so that the all-day heat source supplying quality is effectively guaranteed, requirements of people on heat sources in life are met, and the self-contained heat source system brings convenience for people in life and production, and is favorable for wide popularization and application and particularly suitable for families.

The invention provides a data transmission method, device and system. The data transmission method comprises the steps of, by a relay, obtaining configuration information sent by an upper-end device,wherein the configuration information at least comprises a master-slave relationship among multiple vehicle detectors matched with the relay and a reception time bucket used for receiving event information sent by each vehicle detector; if the event information sent by a master vehicle detector is received in a first reception time bucket corresponding to the main vehicle detector based on the configuration information, waking up a second reception time bucket corresponding to a slave vehicle detector which is associated with the master vehicle detector so as to receive the event information sent by the slave vehicle detector in the second reception time bucket; sending the received event information to the upper-end device; and enabling the first reception time bucket of the master vehicle detector to be opened in real time, and determining whether to wake up the second reception time bucket based on the data received in the first reception time bucket. Through the way abovementioned,the accuracy and comprehensiveness of the received data can be guaranteed, the battery consumption can be saved, and the purpose of low power consumption is realized.
