The present invention provides an earthquake early warning system emergency handling interface device, which mainly includes: a first microprocessor and a second microprocessor which are mutually set in a master-slave mode, output to the corresponding first special relay group and second special relay group through a bus output interface, the control coils of the first railway special relay and the second railway special relay adopt a rated voltage control mode, and the control coils of the third railway special relay and the fourth railway special relay adopt an instantaneous high voltage control mode. The present invention optimizes and dynamically adjusts the working voltage of the relay control coil, improves the pull-in speed of the railway special relay, effectively reduces the alarm output delay time, and further overcomes the technical problem of poor real-time performance of the existing interface device.

The invention discloses a sediment suction device, and particularly relates to the technical field of channel sediment cleaning, the sediment suction device comprises a sediment transportation device, a supporting plate is mounted on the sediment transportation device, a plurality of sediment suction pipes connected with one another are arranged on one side of the supporting plate, and the bottom end of the sediment suction pipe at the bottom is connected with a mud mixing frame; and a rotating rod is rotationally connected to the interior of the fixed mounting frame, and a spiral blade is fixedly arranged at the outer end of the rotating rod. A silt layer is stirred through a plurality of rotating connecting rods, thick silt is conveyed into a silt mixing frame through spiral blades to be mixed with water, silt suction is easy and convenient, the suction speed can be increased, the situation that a silt suction pipe is blocked due to the fact that the silt is too thick is avoided, and the silt suction efficiency is improved. Suction and cleaning of silt can be continuously carried out, the silt suction and cleaning efficiency is effectively improved, and the overall suction and cleaning effect is good.

This utility model discloses a fast-absorbing three-dimensional suspended sanitary napkin, relating to the field of sanitary product technology. It includes a bottom film, a lower core, an upper core, and a top layer. The bottom film includes an adhesive portion and wing portions. The lower core is fixed to the adhesive portion. The wing portions are located around the adhesive portion, and their backs are provided with adhesive for attaching to the user's underwear. Arched elastic sheets parallel to the length of the sanitary napkin are fixed to both sides of the top surface of the lower core. The upper core is fixed to the lower core only at both ends. Elastic cords are fixed to the sides of the upper core, with the other end of the elastic cords fixed to the wing portions. The top layer is fixed to the upper core. This three-dimensional suspended sanitary napkin has excellent anti-leakage and absorbency.

The utility model relates to the technical field of tea leaf packaging, in particular to a vacuum packaging machine for preventing oxidation of tea leaves, which comprises an equipment box body and is characterized in that the right side of the equipment box body is fixedly connected with an object placing plate, the position, close to the left end, of the upper surface of the object placing plate is fixedly connected with an abutting plate, and a suction mechanism is arranged in the equipment box body. The suction mechanism comprises a first air cylinder, a push plate, a suction pipeline and a connecting pipeline, multiple sets of suction holes are formed in the surface of the suction pipeline, a sealing mechanism is arranged on the upper side of the storage plate, and the sealing mechanism comprises a supporting column, a supporting plate, a second air cylinder, a mounting plate and a pressing plate. A telescopic rod in a first air cylinder pushes a suction pipeline into a packaging bag through a push plate, meanwhile, a telescopic rod in a second air cylinder pushes a pressing plate downwards, an opening of the packaging bag is pressed and sealed, tea leaves are effectively prevented from being scattered, meanwhile, the suction pipeline is inserted into the packaging bag for suction, and the packaging bag is more convenient to use. And the speed of sucking air in the packaging bag is effectively increased.
