According to the passivation tool, the smearing uniformity of passivation liquid medicine is better, the liquid medicine is saved, and the passivation effect is improved.

The invention relates to a composite solid electrolyte membrane as well as a preparation method and application thereof. The composite solid electrolyte membrane comprises the following components: polyvinylidene fluoride-hexafluoropropylene, oxide powder, lithium salt and ethyl 3-triethoxy silane propionate. Through reasonable compatibility of the components, the coating uniformity is high, the problems of discoloration and gelation in the preparation process of the composite electrolyte can be obviously improved, and meanwhile, the composite electrolyte has relatively low impedance, relatively high ionic conductivity and excellent performance, and has relatively great application potential in preparation of a solid-state battery. In addition, according to the preparation method of the composite solid electrolyte membrane, repeated washing and long-time treatment are not needed, the process is simple and environmentally friendly, the production time and energy consumption are reduced, and the preparation method is suitable for industrial large-scale application.

The utility model discloses a paper barrel bottom pasting machine, and belongs to the technical field of paper barrel bottom pasting equipment. The paper barrel bottom pasting machine comprises a first rack, a second rack and a support, the first rack is provided with an adjustable storage frame used for containing paper sheets, and the support is provided with a moving module used for adsorbing the paper sheets and driving the paper sheets to move; the second rack is provided with a glue spreading roller mechanism used for spreading glue on paper sheets. The glue spreading roller mechanism comprises an upper glue spreading roller, a lower glue spreading roller and a glue disc used for containing glue. According to the utility model, the paper sheet is directly glued and then is adhered to the bottom of the barrel, so that the problem of glue waste caused by the fact that a gluing area is larger than the paper sheet is avoided, and the gluing roller is adopted to replace a brush to carry out gluing operation, so that the problem of frequent cleaning or replacement of the brush can be avoided; therefore, the problems that in the prior art, a gluing brush is prone to being damaged and needs to be cleaned frequently, and paper cannot completely cover a gluing area possibly are solved.

The invention discloses a helicobacter pylori rapid detection test bar which comprises a base box, a first cavity is formed in the right side of the base box, a second cavity is formed in the left side of the base box, a sliding cover is arranged at the front end of the second cavity and arranged in the left side of the front end wall of the base box in a limited sliding mode, and a top plate is installed at the top end of the base box. Mounting boxes are arranged in the base box at equal intervals, a third cavity is formed in the left side of each mounting box, a fourth cavity is formed in the right side of each mounting box, a liquid box is vertically and slidably connected to the inner side of each third cavity through a first spring, a sealing plate is mounted at the top of each liquid box, and a pressing block is slidably arranged at the upper end of each sealing plate in a limiting mode; by arranging the paper placing assembly, the rotating assembly and the paper placing assembly are matched and linked, so that samples on sampling labels can be uniformly smeared on test paper, and by arranging a plurality of mounting boxes in the base box, single-time single-area detection of multiple persons can be realized during use.

This invention provides a pesticide spraying flow control system based on multi-sensor information fusion, comprising a multi-sensor information acquisition unit, a central control unit, and an execution drive unit. The multi-sensor information acquisition unit is used to collect data in real time on the travel speed, terrain slope, pesticide viscosity, and pipeline flow rate during pesticide spraying operations. The central control unit is configured to: perform parallel advance prediction; generate feedforward control quantities based on the advance prediction results and a dynamic compensation model; the dynamic compensation model is configured to perform coupled compensation based on the terrain slope angle and its rate of change, and compensation based on the temperature-calibrated pesticide viscosity; adaptively tune control parameters online and generate feedback control quantities based on the deviation between the real-time pipeline flow rate and the target flow rate; and weightedly fuse the feedforward control quantities and feedback control quantities to generate a total control command. The execution drive unit is used to adjust the opening of the flow regulating valve according to the total control command to achieve closed-loop control of the spraying flow rate.

This invention relates to cement pole inspection and discloses a cement pole quality inspection device, including a tripod. A positioning mechanism for auxiliary positioning is installed on the front side of the tripod. Above the positioning mechanism is a detection mechanism for detecting defects in the cement pole. A cleaning mechanism for cleaning the inner wall of the cement pole is located at the front end of the positioning mechanism. The positioning mechanism includes three diagonal braces. Each diagonal brace has a support rod hinged to its end away from the sliding block. A wall-supporting wheel is rotatably connected to the end of the support rod away from the tripod. A central shaft is rotatably connected to the axis of the tripod. A shaft groove is provided at the rear end of the central shaft. This invention provides stable, centered support through adaptive tightening, extends the detection depth through threaded extension, and ensures precise control over long distances through shaft-connected transmission, thereby significantly improving the adaptability to cement poles of different specifications and the efficiency of inspection operations.
