The utility model discloses a movable spraying device for a working face, and relates to the technical field of coal mining equipment. The working face movable type spraying device comprises two adjusting type moving structures, a driving structure is arranged between the two adjusting type moving structures, dust falling nozzles are arranged on the inner sides of the adjusting type moving structures, a water storage structure is arranged on the outer side of the adjusting type moving structure on the right side, and the water storage structure is connected with the dust falling nozzles; according to the spraying device with the movable working face, by arranging the adjusting type moving structures and the driving structures, the adjusting type moving structures can adjust the lengths of the adjusting type moving structures so as to change the dust falling height of the dust falling spray head, and then the driving mechanisms are matched to adjust the interval between the two adjusting type moving structures so as to adjust the dust falling range of the dust falling spray head; the size of the spraying device can be flexibly adjusted according to the requirements of the actual working environment, and water mist sprayed in the spraying process can evenly cover the whole working face.

The invention relates to the technical field of food safety detection, and discloses an immunochromatography kit for rapidly detecting rice yeast acid in food, which comprises a test strip and an extracting solution. The test strip is in lap joint with a sample pad, a combination pad, a nitrocellulose membrane and a water absorption pad in sequence; the nitrocellulose membrane is provided with a detection line coated with a rice yeast acid conjugate and a quality control line coated with an anti-mouse IgG antibody. The sample pad is pretreated by polyvinylpyrrolidone to intercept impurities; introducing a steric hindrance protective agent into the combination pad probe; the extracting solution contains methanol and a surfactant. Through a specific formula and process, the technical problems that in a lipid-containing and high-viscosity complex matrix, rice yeast acid is difficult to extract, chromatography is prone to blockage and false positive is caused by an organic solvent are solved, and the method has the advantages of being high in sensitivity, high in anti-interference capacity and rapid in detection and is particularly suitable for food poisoning site emergency disposal and daily rapid screening.

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.

The invention belongs to the technical field of underground construction engineering, and particularly relates to an overpass existing subway tunnel protection structure which comprises isolation piles. A plurality of isolation piles are arranged, and the plurality of isolation piles are divided into three groups; the multiple isolation piles are arranged as main supporting components, the overall stability of the structure is enhanced, the isolation piles serve as anti-floating piles of the underground transportation hub structure, the anti-floating capacity of the structure is improved, and due to the arrangement mode of the three sets of isolation piles, when the structure bears loads, force can be more evenly dispersed, local stress concentration is avoided, and the service life of the structure is prolonged. The four inserting holes formed in the fixing frame provide accurate positions for inserting of the inserting plates, it is ensured that the conversion raft plate can be stably hoisted on the fixing frame, the conversion raft plate serves as a bottom plate of the underground transportation hub structure, the upper load is borne, the load is transmitted to the multiple isolation piles through connection with the fixing frame, and therefore the conversion raft plate is prevented from being damaged. And the bearing capacity of the structure is further enhanced.

The utility model discloses intelligent control spraying device, including the bottom plate, two diffuse reflection switches and a controller are fixedly installed to the bottom plate upper end surface through the mounting panel, the bottom plate outer wall is fixedly installed with frequency conversion water pump through the support mechanism, the bottom plate upper end surface is fixedly installed with dust concentration detector through the support rod, the bottom plate upper end surface is fixedly installed with the connecting pipe of frequency conversion water pump export end connection through the mounting groove, the bottom plate upper end surface is fixedly installed with a plurality of with the connecting pipe cooperation's clamp through the bolt. The utility model discloses through setting diffuse reflection switch, dust detector, first spraying pipe and second spraying pipe etc. component, under the cooperation of two diffuse reflection switches, can determine the in and out of vehicle, thereby can control the opening and closing of the washing water, and through the setting of dust concentration detector, the concentration of dust can be accurately detected, so that the first spraying pipe and second spraying pipe can be cooperated to realize the effective settlement of dust.
