The disclosure provides a cleaning device and a substrate cleaning method. The cleaning device includes a driving part, a plurality of gripping parts, a plurality of telescopic rods and a cleaning part, the driving part includes a driving motor, a guide rail and a plurality of sliders arranged at intervals on the guide rail, and the gripping part is used for grabbing and placing To clean the substrate, one end of the telescopic rod is connected to one or more grasping parts, and the other end of the telescopic rod is connected to the slider. The telescopic rod is used to adjust the distance between the grasping part and the driving part. The cleaning part is set on The gripping part is away from the side of the driving part, so that the surface to be cleaned of the substrate faces the cleaning part, and the bottom-up cleaning of the substrate is realized. The cleaning liquid generated by the cleaning part drops due to the influence of gravity, so as to solve the cleaning problem. For the problem of device liquid backflow, the pollutants attached to the surface of the substrate to be cleaned will not cause secondary adhesion due to gravity, thereby improving the cleaning effect of the cleaning device for cleaning the substrate.

The invention relates to an integrative cooking utensils of lampblack absorber and cooker, comprising a cabinet body, a plurality of cylindrical sunken stove holes are formed in the panel of the body, a cooker is provided on the soleplate of the stove holes, a handle hole in one side of the stove holes faces person, the air inlet of a blower is set in the gas collecting tank. The blower is connected with an exhaust pipe; a lifting ring can be connected to the outer face of wall of the cooking stove sleeve in sliding way, and the cavity of the lifting ring is connected with the gas collecting tank; when the lifting ring lifts, inside part exposed from wall of the cylindrical stove holes is opened with an air suction port, and the lifting ring is connected with a driving mechanism so as to avoid the outside air from flowing back.

The invention relates to a multitube convergence inspection well with tube tops in flush joint. The multitube convergence inspection well comprises a well shaft, a well base, and a bell mouth which is arranged on the well base and connected with a main pipeline, wherein a well lid base and a well lid are arranged on the well shaft; at least two interfaces connected with branch pipelines are further arranged on the well base in parallel; each interface comprises a pipeline bell mouth integrated with the main pipeline; pipe joints of two or three pipe diameters in a small hole, a medium hole and a big hole are coaxially arranged on the well base; and central lines of the pipe joints are arranged above the central line of the well base. The multitube convergence inspection well disclosed by the invention is novel in conception, the pipe joints of the most three common specifications are coaxially arranged and can be machined on site according to actual needs in a construction site, the operation is simple and convenient, and the multitube convergence inspection well in such a structure is more beneficial to large-batch manufacture, so that the production cost is lowered and the production cycle is reduced; and the upper edge of the pipe joint with the maximal pipe diameter is parallel and level to the upper edge of the well base, so that falling is formed due to water level rise during pollution or water discharge, and thus, the flow rate of discharged pollution or water is increased and the problem of downstream backward flowing is solved.

The invention relates to a rainwater and sewage flow converging and intercepting device. The device is characterized by comprising a well body, an isolation plate, an overflow weir and a louvered valve. The well body is made of high molecular material in an integrated injection molding mode. A flow converging tube, an overflow tube and a flow intercepting tube are arranged on the well body. The interior of the well body is divided into a water inlet cavity, a water drainage cavity and an overflow cavity through the overflow weir, the louvered valve and the isolation plate. The flow converging tube is communicated with the water inlet cavity, the overflow tube is communicated with the overflow cavity, and the intercepting tube is communicated with the water drainage cavity. According to the rainwater and sewage flow converging and intercepting device, the well body is made of the high molecular material in the integrated injection molding mode, so that the leakage problem of a traditional bricked well is solved, and secondary pollution is eradicated; through reasonably arranging the water inlet cavity, the water drainage cavity and the overflow cavity, the device achieves rainwater and sewage flow converging and intercepting, and meanwhile the problem that external water bodies flow backward is solved.

This application relates to the technical field of nuclear auxiliary systems of nuclear power plants, and discloses a nuclear island exhaust and water delivery pipe network system for mega-kilowatt nuclear power plants, including a first pump set, a first drain pipeline, a second pump set, a Two drain pipelines and containment drain pits. The first pump group includes a first water pump and a first drain pan, one end of the first drain line communicates with the first drain pan, and the leakage water in the first drain pan is discharged into the first drain line. The second pump set includes a second water pump and a second water receiving pan, and one end of the second drainage pipeline communicates with the second water receiving pan. The other end of the first drainage pipeline and the second drainage pipeline converge into one pipeline and extend to the containment drainage pit. In the improved nuclear island exhaust and water delivery pipe network system, an independent drainage line is formed between the first drain line and the second drain line and the containment drain pit, which can meet the requirements of the first drain line and the second drain line. The pipeline's demand for drainage volume and drainage speed is conducive to solving the problem of wastewater backflow.
