This invention belongs to the field of supercapacitor technology, specifically relating to a molybdenum oxide-molybdenum disulfide@polytannic acid electrode material, its preparation method, and its applications. Using molybdenum foil as the current collector and electrode, this invention prepares a molybdenum oxide-molybdenum disulfide electrode using electrochemical oxidation and hydrothermal methods. A polytannic acid coating is deposited on its surface to prepare a biodegradable molybdenum oxide-molybdenum disulfide@polytannic acid electrode. This electrode is then sandwiched with a biodegradable gel electrolyte and encapsulated with a biodegradable encapsulation material to construct a biodegradable supercapacitor with self-discharge suppression capabilities. By depositing a polytannic acid coating on the surface of the supercapacitor electrode, its self-discharge behavior is suppressed. The polytannic acid coating can prevent parasitic Faraday reactions of impurity ions on the electrode surface and prevent charge transfer, thereby suppressing the capacitor's self-discharge behavior. Simultaneously, the electrode, electrolyte, and encapsulation material can all degrade in simulated body fluids, potentially opening up applications in implantable medical electronic devices.

This utility model discloses a building fire simulation training device, including an upper simulation area and a lower simulation area, both constructed using shipping containers. The lower simulation area includes a furniture fire simulation training room, a kitchen fire simulation training room, an electrical fire simulation training room, and an oil fire simulation training room. The outer wall of the oil fire simulation training room has a gas storage chamber, and a gas delivery pipeline is installed on the gas storage chamber, one end of which is connected to the gas storage chamber. The gas delivery pipeline surrounds the outer wall of the lower simulation area. A bed fire model is installed in the furniture fire simulation training room directly opposite the igniter; a kitchen fire model is installed in the kitchen fire simulation training room directly opposite the igniter; and an electrical fire model is installed in the electrical fire simulation training room directly opposite the igniter. This utility model provides a variety of training scenarios and good training results, with the upper simulation area used for comprehensive fire simulation training and the lower simulation area used for real fire simulation training.

This invention discloses a waste filtration and collection device for a swimming pool underwater cleaning robot, comprising: a shell with an inlet channel and an outlet channel; the inlet channel having a confluence channel and two suction channels; the two suction channels are located at the bottom of the shell and converge to the lower end of the confluence channel; the upper end of the confluence channel extends into the inner cavity of the shell and divides the inner cavity into front and rear waste compartments; the outlet channel has a drain channel and two filter channels; the drain channel is located at the top of the shell, with a water pump impeller installed at the drain outlet at the upper end of the drain channel, and its lower end confluences and connects to the upper ends of the two filter channels; the lower ends of the two filter channels are equipped with filter screens, which correspond to the inlets of the front and rear waste compartments respectively; both ends of the confluence channel are gradually expanding openings, with the upper end guiding the flow direction towards the front and rear filter screen areas respectively. This invention can effectively reduce the flow resistance of the entire channel, reduce the power consumption of the swimming pool cleaning robot, and thus extend the effective working time of the robot.

This invention relates to the field of electrostatic powder coating technology and discloses a powder coating device, including a spray gun nozzle, a plurality of spray gun nozzles arranged at intervals, and a baffle plate disposed between two adjacent spray gun nozzles. The baffle plates on both sides of the spray gun nozzles are symmetrically arranged, and each spray gun nozzle is installed on the same horizontal plane. The ends of two adjacent baffle plates are connected, and the ends of each baffle plate are located on the same horizontal plane, which is parallel to the horizontal plane where the spray gun nozzles are located. The powder sprayed from the spray gun nozzles passes through the ends of the baffle plates on both sides and can perform spraying on the material to be coated in a manner that meets the spraying requirements. Its advantage is that it can intercept uneven powder spray and improve the uniformity of powder coating.
