This utility model discloses an integrated knitting and sewing machine for socks, including a knitting station and a sewing station. The knitted sock blank is transferred from the knitting station to the sewing station. The sewing station has a downward-opening tubular mechanism into which the sock blank enters from bottom to top. A sock-pressing component is provided between the knitting and sewing stations. This component is a slender rod, rotatably mounted on the machine frame at one axial end. The rotation direction of the pressing rod is vertical and perpendicular to the line connecting the knitting and sewing stations. This utility model facilitates the extraction of the sock blank from the needle cylinder in the knitting station and is suitable for sock sewing machines with a downward-opening tubular mechanism.

The present invention provides an elevator safety alarm device, which belongs to the technical field of elevators; it includes an elevator car and a left door and a right door installed at the opening of the elevator car, the left door and the right door are both fixed with frames, an audible and visual alarm is installed in the elevator car, and it also includes: a shell, the number of the shells is two, the two shells are respectively arranged on the side of the left door and the right door away from the elevator car, and the two shells are both provided with a detection component and a driving component. The driving component, the detection component and the audible and visual alarm of the present invention, when there is transparent glass between the left door and the right door, the contact sensor is triggered under the reaction force applied by the transparent glass, and then the left door and the right door can be opened, and when a rope-like object is detected, the driving component drives the infrared transmitter and the infrared receiver to descend at the same time, and the rope-like object in the blind spot can be detected, and then the left door and the right door are opened, so as to realize the safe operation of the elevator.

The application discloses an anti-internal-flooding urban drainage device, and belongs to the technical field of drainage equipment. The technical scheme is as follows: the anti-internal-flooding urban drainage device comprises a water passing pipe arranged in a road shoulder and communicating with the outside at one end, a transition groove communicating with the water passing pipe, and a water storage pool located below the transition groove, the water storage pool communicates with the transition groove through a first connecting pipe, a filtering assembly is connected in the water passing pipe, the filtering assembly comprises a mounting plate abutting against an opening of the water passing pipe close to the outside, a fixing rod connected with the mounting plate, and a plurality of branch rods connected with the fixing rod, a plurality of water passing holes communicating with the water passing pipe are horizontally formed in the side wall of the mounting plate, the ends, away from the fixing rod, of the plurality of branch rods abut against the inner wall of the water passing pipe, and the ends, away from the fixing rod, of the plurality of branch rods are inclined towards the outside, so that the occurrence of urban internal flooding is reduced.
