An aircraft tail section comprises: - a vertical tail; - an aft fuselage section attached to the vertical tail and comprising a skin and internal stiffening members; - a horizontal tail comprising two lateral torsion boxes and a frame structure between the two lateral torsion boxes, the frame structure comprising a front spar, a rear spar and two ribs extending between the front spar and the rear spar, and each rib being adjacent a lateral torsion box. The frame structure encloses a portion of the vertical tail along a spanwise direction of the vertical tail. The aircraft tail section comprises an attachment assembly attaching the frame structure to the aft fuselage section, the attachment assembly crossing the skin and extending between the internal stiffening members of the aft fuselage section and the frame structure.

This utility model discloses a pipeline rescue and safety device, belonging to the field of pipeline repair. It includes a pipe tube with a main baffle fixedly connected to its top. A sealing gasket is placed between the pipe tube and the main baffle. A secondary baffle, coaxially arranged with the main baffle, is connected to the top of the main baffle via connecting bolts. The main baffle has a first drain port, and the secondary baffle has a second drain port corresponding to the first drain port and of the same size. The secondary baffle can rotate around the connecting bolts, and the rotation of the secondary baffle controls the opening and closing of the first and second drain ports. A sealing ring groove is provided on the main baffle at the edge of the first drain port. This pipeline rescue and safety device replaces traditional methods of using airbags and bricks to block water, avoiding safety accidents caused by water leakage due to airbag rupture, and also solving the accident risk caused by sudden water gushing out when removing brick plugs, thus ensuring the safety of personnel working in manholes or pipes.

The invention discloses a composite spinning box for superfine denier ES fiber production, the composite spinning box comprises a box body and a spinning assembly, the box body is provided with a spinning chamber, and the spinning assembly is installed in the spinning chamber; the spinning assembly comprises a spinneret plate and a partition plate; the spinneret plate comprises a first plate body and a second plate body, the first plate body and the second plate body are connected into a whole, a skin component circulation gap is reserved between the first plate body and the second plate body, the first plate body is provided with a composite spinneret hole, a core spinneret body is arranged on the side, away from the first plate body, of the second plate body, and the core spinneret body and the installation hole are kept concentric. The core spinneret body is provided with a core spinneret hole communicated with the composite spinneret hole; the spinneret plate is located on one side of the partition plate, the partition plate is provided with a skin component supply hole and a core component supply hole, and the core component supply hole communicates with a gap between the second plate body and the partition plate; and the spinneret plate is provided with a skin component drainage hole communicated with the skin component supply hole.

The utility model discloses an aquaculture pond outside shellfish shell collecting device through circulating water pipeline collection, be applicable to factory shrimp culture field. The shrimp pool bottom outlet is used to realize the separation of shrimp manure and shellfish shell with shellfish live shrimp baffle, and the shellfish shell is blocked at the shellfish live shrimp baffle, and the smaller solid dirt such as shrimp manure is filtered through the baffle filter hole after using the circulating water flow, and then is discharged to the shellfish shell collecting basket in the pool side water level tank through the circulating pipeline, and then flows to the microfiltration machine after the filter hole of the shellfish shell collecting basket. When the shellfish shell accumulates to a certain number at the shellfish live shrimp baffle, the shellfish live shrimp baffle is lifted by using the rope, and the gap below the baffle is formed than the shellfish shell, and the shellfish shell is driven by the circulating water flow and flows to the shellfish shell collecting basket through the pipeline, and since the volume of the shellfish shell is larger than the shellfish shell collecting basket blowoff drain hole, the shellfish shell is blocked in the shellfish shell collecting basket. Thus, a single pipeline can satisfy the circulating water flow and the shellfish shell collection. In addition, the shellfish shell collecting basket is full of shellfish shell, and the shellfish shell can be easily taken out from the pool side water level tank and poured.
