The invention provides a grounding device for a falling-type fuse. An aim of reliable grounding can be fulfilled by connecting a grounding suspension ring to a grounding bar at the lower end of a falling-type fuse main body by a fixing nut.

Disclosed is a manufacturing process for an antistatic hard coating plastic film, comprising a first step of coating an antistatic hard coating onto the surface of a plastic film substrate and a second step of irradiating the antistatic hard coating with ultraviolet rays so as to react organosilicon with multifunctional acrylate monomers under the condition of an initiator. The antistatic hard coating plastic film provided in the invention has not only excellent antistatic performance, but also good sharpness and scratch resistance. Therefore, such antistatic hard coating plastic films can be used in liquid crystal display devices or be used as films for the protection of various image display devices.

The invention relates to a method for reducing coal consumption by cyclic utilization of waste heat of a Webster furnace. According to the method, heat generated by the exothermic reaction process is collected for the endothermic reaction process by means of the reaction principle of smelting zinc oxide by a direct method in production of the Webster furnace, so that heat is recycled, the use level of coal required for the endothermic process is reduced, the fuel coal and reducing coal required in the reaction process are saved, and the power consumption can be reduced by 30%. From the oxidizing chamber of the Webster furnace, cooling and settling processes of zinc oxide smoke are performed, and heat exchanged in the processes can be used for drying agglomerates. The agglomerates are prepared from mixtures of zinc-containing materials, coal and the like which are pressed to pellets through a ball press machine. Before the agglomerates enter into the hearth to be smelted, the agglomerates can be aired till the moisture is lower than 8%. By using the method, the drying time of the agglomerates can be accelerated, and the production efficiency is improved by over 10%.

A method for optimizing a track planning algorithm, comprising: S1. According to the current position of the ship and the position of the target point, the track planning algorithm is used to obtain the node set O used to determine the waypoint in the track planning and the node set that has already determined the waypoint C; S2. For each node in the set C, use the Dijkstra search method to obtain the target bounding box of each node; S3. When traversing the neighborhood of each node in the set C to search for the next feasible node, select the current node within the neighborhood of The node in the non-obstacle area and within the target bounding box of the current node is used as the next feasible node; according to the next feasible node, the set O is updated to judge the waypoint; S4, traverse the set C, and obtain the optimal track route. It not only avoids the path planning algorithm to explore redundant and invalid nodes, but also prevents the path planning algorithm from exploring nodes to expand in the wrong direction, thereby speeding up the speed of path finding and improving the efficiency of algorithm operation.

The invention discloses a neutral buoyancy trimming device for realizing a wrist structure of an underwater mechanical arm. The neutral buoyancy trimming device for realizing the wrist structure of the underwater mechanical arm comprises a wrist joint, a silicone shell, chambers and valves; N grooves (N is a natural number which is greater than or equal to 2) are formed in a shell of the wrist joint, the N grooves form the chambers, and the chambers are uniformly distributed along the circumference to form semi-circular and circular closed cavities; and the shell of the wrist joint is coveredwith the silicone shell; the valves are located on the silicone shell and are arranged directly above each chamber for enabling the chambers to be filled with gas or non-Newtonian fluid to adjust volume and density to achieve neutral buoyancy trimming. According to the neutral buoyancy trimming device for realizing the wrist structure of the underwater mechanical arm, the internal structure is notchanged, only the density and volume on the shell are changed to achieve equal gravity and buoyancy, and the center of gravity coincides with the center of buoyancy. The silicone of the device is resistant to corrosion, and the corrosion resistance of the wrist structure is improved; the trimming method is simple, the weight of the device is reduced, and the design cost is reduced; and the tightness of the device is improved, the number of the underwater equipment is effectively reduced, and the entire simulated weightlessness training process is enabled to be more convenient.
