The invention relates to the technical field of internet-of-things monitoring devices, in particular to a pipeline liquid level internet-of-things monitoring device based on a pressure sensor, which comprises a container, a placing box is arranged on the front side of the container, and the placing box can be adsorbed in front of the container through a sucker or hung in front of the container through a rope. The placing box is connected with a power plug, the container is connected with a pipeline, the pipeline is connected with a tee joint, a drying agent is placed in the storage box before the box cover is connected with the placing box, the drying agent is beneficial for preventing moisture from being generated in the placing box, and when the box cover is connected with the placing box, a pressing plate on the inner side of the box cover enters a groove, so that moisture is prevented from being generated in the placing box; the diameter of the pressing plate is one third of that of the groove, when the pressing plate enters the groove, the pressing plate presses the air bag, then a part of the air bag is extruded out of the groove, the extruded part is beneficial to filling a gap at the joint of the box cover and the placing box, and dust or moisture can be prevented from entering from the gap.

The utility model relates to the technical field of commodity vending machine discloses a cylindrical helical self -gravity compensation position commodity vending machine, including, bearing mechanism, including the cylinder and the hinge in the cylinder outside by solenoid valve control openable and closable baffle, gravity compensation position mechanism, including the cylindrical cylinder of installation in the inner chamber of cylinder, the utility model discloses a double helix conveying system that constitutes by first spiral guide rail and second spiral guide rail, and the rotation clamping of first variable -pitch compression spring and second variable -pitch compression spring are matched, realize the helical self -gravity compensation of commodity, and the efficiency of replenishment is effectively promoted, and the cylindrical modeling of cylinder and customizable shell break through the traditional square cabinet body limit, make the equipment have functional and design aesthetic feeling, and the multistage buffer system that buffer block and spacing baffle constitute ensures the reduction of breakage rate when the special-shaped commodity is transported, and the gravity compensation position mechanism of modular design supports 3 5 layer flexible configuration, and can adapt to the different scene demand such as shopping mall, scenic spot.
