4results about How to "Safe and Efficient Storage" patented technology

The application discloses a cover plate assembly, a battery monomer, a battery device and an energy storage device, and belongs to the technical field of batteries. The cover plate assembly is applied to a battery monomer and comprises a cover plate and a pressure relief structure. The cover plate is provided with a pressure relief hole, and the pressure relief structure is mounted on the cover plate. The pressure relief structure comprises a plurality of valve opening bodies which are distributed at intervals along a first direction. The valve opening bodies are connected to the cover plate and close the pressure relief hole. The valve opening bodies are provided with a plurality of notches. In the technical scheme of the application, the plurality of valve opening bodies can reduce the risk of deformation of the pressure relief structure and the battery monomer shell caused by excessive pressure change, and reduce the influence of deformation of the valve opening bodies on the normal work of the whole pressure relief structure after long-term use.

The application discloses a method for constructing an internal dumping site based on a fly ash-based cementing material carbon dioxide storage, and utilizes the cementing properties of fly ash of a pit mouth coal-fired power plant to prepare a fly ash-based cementing material with super high content, and utilizes the high-strength fly ash-based cementing material to construct a carbon dioxide storage, and utilizes a cement-free low-strength fly ash-based cementing material to backfill an open-pit mine pit, so that the resource utilization and efficient collaborative disposal of fly ash solid waste are realized; the carbon dioxide storage is constructed in the internal dumping site space, the open-pit mining space is effectively utilized, and the problem of insufficient material for land reclamation backfilling in the late mining stage is solved; the carbon dioxide storage reinforced by the anchor rod prestress has high strength and large internal space, the mine pit bottom plate impermeable layer and the overlying clay cover layer increase the airtightness, and the safe and efficient large-scale storage of critical state carbon dioxide is realized; the fly ash-based cementing material can mineralize carbon dioxide in a humid environment, increases the carbon dioxide storage amount, and improves the carbon dioxide storage strength and airtightness.

The invention belongs to the technical field of hydrogen energy storage, and particularly relates to a liquid hydrogen well hanging and supporting device. The liquid hydrogen well hanging and supporting device is arranged at the bottom of an inner shaft, the inner shaft is located in an outer shaft, and the liquid hydrogen well hanging and supporting device comprises a load bearing support and a supporting rod, the multiple hanging ropes are evenly arranged in the circumferential direction of the bearing support, and the end, away from the bearing support, of each hanging rope is connected with the shaft wall of the outer shaft. The invention can reduce the loss of liquid hydrogen.

The invention discloses a scenic spot management interactive method and system based on big data, and particularly relates to the technical field of tourism management and intelligent scenic spots, an access control gate machine, an electronic ticket card reader and a tourist information management terminal are arranged to record incoming and outgoing data of tourists, and a ticket system is connected with a database to realize real-time transmission and storage of the data; high-definition monitoring cameras and visitor flow counting equipment are installed at main entrances and exits of scenic spots and important scenic spots, the number of tourists is monitored in real time and accurately counted, and RFID equipment is configured for recognizing and tracking the identities and positions of the tourists; the system is provided with an access control gate machine, a monitoring camera, RFID equipment and the like, acquires tourist data in real time, models by using multiple algorithms such as linear regression, random forest and LSTM, processes in real time and combines multiple algorithms to inform management personnel to take measures in time, so that excessive concentration of tourists is avoided, and the operation efficiency and safety of scenic spots are improved; and meanwhile, data support is provided for management decisions.
