The invention discloses an automatic hydraulic control leaping weir initial rainwater catch basin and a flow closure method. The automatic hydraulic control leaping weir initial rainwater catch basin and the flow closure method are suitable for the improvement of a bypass flow rainwater pipeline. The catch basin comprises a catch basin body, a flow inlet pipe, a water closure pipe, an automatic hydraulic control weir body, four limiting blocks, a floating cylinder, sector flow side baffles, flow discharging small holes, a separation wall, an overflowing pipe, a manhole, steps, a weir plate shaft and the like. The flow closure method is conducted by the catch basin and when it rains, flow of the water inlet pipe is enlarged along with the enlargement of rainfall. When the flow of the water inlet pipe is enlarged to a certain degree, a flow-jetting outer curve crosses the automatic control weir. According to the automatic control weir, a weir plate is opened under the buoyancy of the floating cylinder and the water flow in the flow inlet pipe is completely abandoned until the amount of the water flow of the flow inlet pipe is nearly zero. Due to the flow discharging action of the flow discharging small holes, the floating cylinder descends, the weir plate is reset, and clean rainwater can enter a water receiving body at the later period. The catch basin is completely controlled through hydraulic power, other control devices are not needed, operation is stable, maintenance is simple, and management is convenient.

The invention concerns a motor vehicle comprising a structure with a first floor (10), the first floor (10) including a substantially flat raised first zone (11) and a low zone (12) adjacent the first zone (11). The low zone (12) is surrounded by a raising frame (14), a second floor (15) being mechanically fixed on the frame (14) in a plane aligned with that of the first zone (11).

The invention provides a device for shoveling fallen leaves on a community lawn with deformable local parts and a using method, and relates to the field of garden equipment. The device for shoveling the fallen leaves on the community lawn with the deformable local parts comprises a leaf fishing treatment box, wherein side boxes are bonded to the side walls of the leaf fishing treatment box, a lever lifting mechanism is arranged at the top of the leaf fishing treatment box, a top fixing plate is arranged above the leaf fishing treatment box, side feet are welded to the four corners of the bottom of the top fixing plate, side bottom rods are bonded to the bottoms of the side feet, and the bottoms of the side bottom rods are inserted into the tops of side bottom cylinders. According to the device for shoveling the fallen leaves on the community lawn with the deformable local parts, when an end arc rod makes contact with a heavy object, a close connecting rod making contact with the heavy object is bent in the clockwise direction, meanwhile, the end arc rod and the close connecting rod can also be bent, the fallen leaves are shoveled by other parts not making contact with the heavy object normally, therefore, by means of the device, heavy objects such as stones and the like can be removed, operation of the device is prevented from being affected, and meanwhile, the fallen leaves in some narrow positions can be conveniently fished out.

The invention relates to the field of lung capacity training equipment, in particular to a medical lung capacity training equipment and its working method, comprising an air blowing mechanism, a lung capacity detection mechanism, a booster mechanism and an anti-suckback device, the anti-suckback device includes a branch pipe, a standpipe, an oxygen tank, a horizontal pressing mechanism, an opening and closing mechanism, two lifting mechanisms and a connecting mechanism, and the two connecting mechanisms are respectively fixedly installed on both sides of the branch pipe. Oxygen undergoes transitional pollution. When the patient is inhaling, the anti-suckback device can allow the patient to inhale the oxygen in the oxygen tank in time, and the patient's mouth does not need to be removed from the flat mouthpiece during the inhalation process. , and the blown gas will not return to the patient's lungs, preventing germs from returning to the patient's lungs along the blown gas, reducing the possibility of the patient's illness and improving the enthusiasm of the patient.

The invention provides a composite fabric with built-in medicine powder, its production method and application. The composite fabric includes a water-repellent and antibacterial outer layer, a nanofiltration layer, an antibacterial fabric layer and a unidirectional moisture-conducting layer that are sequentially stacked, and the antibacterial fabric layer is a woven fabric layer containing a built-in drug powder yarn. With such a setting, on the one hand, the nano-filtration layer is used to block the invasion of nano-scale viruses from the outside; on the other hand, the moisture vapor of the virus on the population side is guided into the woven fabric layer to kill the virus through the one-way moisture-conducting layer. The invention adopts strip-type orderly stacking to produce composite fabrics, creatively integrates the integrated processing of non-woven, woven and knitted fabrics, and synergistically exerts the properties and functions of each fabric. The composite fabric prepared by the invention has good bactericidal, antibacterial, anti-virus functions and good sterilization persistence, and can prevent the virus on the composite fabric from returning to the air, solve the problem of secondary damage, and can be used for haze prevention, sterilization, Composite fabrics such as antibacterial or antivirus materials.
