The application belongs to the technical field of steel structure roof truss installation, in particular to a quick installation auxiliary device for steel structure roof truss installation, comprising a plurality of vertical steel beams and a crane, the vertical steel beams are arranged in linear array on the ground, the upper end surfaces of all vertical steel beams are jointly provided with a frame-shaped plate, a composite truss is arranged above the frame-shaped plate, the composite truss is hoisted to above the frame-shaped plate by the crane, a fastening mechanism is arranged at the bottom of the crane, the fastening mechanism is used for fastening the two side surfaces of the frame-shaped plate, the fastening mechanism comprises a connecting rope installed above the crane; the fastening mechanism can automatically take out the connecting rope from the surface of the composite truss, without the need for workers to manually untie the connecting rope, the operation is relatively safe, convenient and fast, which is beneficial to the installation of the composite truss, and the hoisting mode of the remaining composite trusses is also the same, so that they are arranged in linear array above the frame-shaped plate, so that the roof truss can be quickly installed.

The application provides an organic lithium-iodine battery based on a two-electron transfer mechanism and a manufacturing method and application thereof. The organic lithium-iodine battery comprises a positive electrode, a negative electrode and an organic electrolyte. The positive electrode active material used by the positive electrode comprises iodide and / or bromide, and the organic electrolyte comprises an organic solvent containing a chlorine-containing additive. The organic lithium-iodine battery uses iodide as the positive electrode active material, thereby avoiding the instability and safety hazards existing in the current I2 positive electrode. The organic solvent containing the chlorine-containing additive is used as the organic electrolyte, and excellent electrochemical performance is provided through a two-electron conversion mode. Compared with a traditional lithium-iodine battery, the organic lithium-iodine battery has higher capacity, energy density and higher output voltage. In addition, the organic lithium-iodine battery has excellent low-temperature insensitivity. At-25 DEG C, the battery realizes 2500 cycles at the cost of 20% capacity decay, and can still work stably at a low temperature of-30 DEG C.

The application discloses a navigation three-screen interactive control method and system, a vehicle and a storage medium, and relates to the technical field of vehicle control. The method comprises the following steps: in response to detecting that an automatic screen projection function has been activated, a long-time application trigger, and the fact that the instrument screen can execute navigation screen projection, the instrument screen displays full-screen navigation; in response to detecting that the automatic screen projection function has been activated, the long-time application trigger, and the fact that the instrument screen cannot execute navigation screen projection, but the third screen can execute navigation screen projection, the third screen displays full-screen navigation; in response to detecting that the automatic screen projection function has been activated, a short-time application trigger or the fact that the car machine screen is switched from desktop one to desktop two, and the fact that the third screen can execute navigation screen projection, the third screen displays full-screen navigation; and in response to detecting that the automatic screen projection function has been activated, the short-time application trigger or the fact that the car machine screen is switched from desktop one to desktop two, and the fact that the third screen cannot execute navigation screen projection, but the instrument screen can execute navigation screen projection, the instrument screen displays full-screen navigation. The application realizes automatic switching of navigation information among the car machine screen, the instrument screen and the third screen.

This utility model discloses a foldable, storage-friendly cylindrical children's play tunnel, relating to the field of children's toy technology. It includes a crawling tunnel toy, an inner tunnel cylinder, decorative leaves, and side support plates. The inner tunnel cylinder is fitted to the inner wall of the crawling tunnel toy. When in use, the inner wall of the inner tunnel cylinder features various patterns, making it easy for infants to observe and judge the shapes while crawling, thus enhancing their cognitive abilities. The inner tunnel cylinder is composed of multiple sections, each made of different materials, which can exercise the infant's tactile senses. Furthermore, the inner tunnel cylinder, through a component controller, can drive a twisting tube to make the crawling tunnel toy twist, increasing the enjoyment for the infant while crawling. Simultaneously, the chip inside the component controller has recording and voice-controlled playback functions, enhancing the infant's auditory and visual perception abilities and increasing the tunnel toy's fun and cost-effectiveness.
