The utility model belongs to the technical field of road paving, and particularly relates to a permeable pavement structure of a road, which comprises a roadbed layer, road edge stones and curbs are respectively arranged on two sides of the roadbed layer, a permeable surface layer is arranged above the roadbed layer and between the road edge stones and the curbs, and a water diversion structure is arranged in the permeable surface layer. A water storage ditch is formed in the side, close to the curb, of the water diversion structure, a drainage ditch is arranged above the water storage ditch, and the water diversion structure is used for introducing water flowing through the permeable surface layer into the water storage ditch; the water storage ditches are formed in the side face of the permeable surface layer, the situation that settlement and sinking of the road surface are found due to the conditions of heavy-weight vehicle driving and the like is avoided, the service life of the road is guaranteed, and the working intensity of maintenance is reduced; on the other hand, water vapor can conveniently penetrate through the permeable surface layer through the water diversion structure at continuous high temperature, and the effect of cooling the surface of the road is achieved.

This invention discloses a mobile firefighting equipment specifically designed for lithium battery fires, comprising an autonomous firefighting robot, a guide hose, and a trailer. Based on multi-sensor data fusion, it achieves automatic fire source identification and location, automatic mapping, autonomous navigation, and automatic firefighting, making it suitable for scenarios requiring rapid response and safe firefighting. The mobile chassis houses an industrial control computer, a GNSS navigation module, a mobile power supply module, and a heat dissipation module. Sensors and signal receiving equipment are located on top of the chassis. A thermal imager identifies the fire source, and combined with lidar and a depth camera, it achieves environmental modeling and autonomous obstacle avoidance in complex fire scenes. The industrial control computer calculates the target pose in real time based on sensor data and controls the high-pressure water cannon to aim at the fire. The trailer integrates a high-pressure water pump to provide continuous firefighting power. This solves the problem of limited perception in dense smoke and high-temperature environments. While ensuring a high water capacity, it enhances the robot's intelligence level and has extremely high practical application value.

The invention provides a horizontal liquid helium container. The horizontal liquid helium container comprises an outer container, a suspension supporting structure, an inner container, a cold shield and a reinforcing ring, a vacuum cold insulation layer is formed between the outer container and the inner container; the cold shield is arranged between the outer container and the inner container; the outer container is connected with the cold shield through the suspension supporting structure, and the inner container is connected with the cold shield through the suspension supporting structure; the outer wall of the inner container is wrapped with a winding type heat insulation layer; and a plurality of groups of reinforcing rings are arranged on the outer wall of the outer container at intervals. The vacuum cold insulation layer is arranged, the cold shield is arranged in the vacuum cold insulation layer, the inner container, the cold shield and the outer container are connected through the suspension supporting structure, and the winding type heat insulation layer is arranged outside the inner container, so that the cold leakage phenomenon is reduced. By arranging multiple groups of reinforcing rings on the outer container at intervals, the structural strength and stability of the outer container are enhanced, and the phenomena of fatigue and failure of equipment can be effectively prevented.
