The present invention discloses an optical cable branching protection structure. The optical cable branching protection structure comprises: a main optical cable, a plurality of sub-optical cables formed by branching the main optical cable, and a deconcentrator sleeved at the outside of the branching of the main optical cable and a plurality of sub-optical cables. A junk ring bush compressing a coating layer sleeves the outside of the main optical cable section, and the sub-optical cable sections have no a junk ring bush. Aramid fibers are located between the coating layer and the steel pipe, and the movement of the aramid fibers may be effectively utilized to make optical fibers in the main optical cable have enough free activity space, so that the optical fibers have enough length to satisfy various usage environment and the optical performance and signal transmission effect of the optical fibers are ensured. According to the invention, single core fibers and aramid fibers are located in the steel pipe, the steel pipe and the coating layer are integrated into one body to fix with a thermoplastic pipe, and the length of the outer coating layer may be determined; and when a branching is made, length of each single core sub-optical fiber is controllable, and the length consistency of the branch sub-optical fiber may be effectively ensured.

The invention discloses a super-hydrophilic and gradient hole structured hollow fiber membrane. The surfaces of the hollow fiber membrane and gradient holes contain super-hydrophilic amphipathic block polyether modified organosilicon; the gradient holes adopt a micro-nano ball-shaped network structure, namely, the gradient of hole diameters is increased from the outer surface layers to the inner surface layers along the radial cross section of the hollow fiber membrane. According to the invention, through adjusting and controlling the length and relative proportion of hydrophobic chain segments and hydrophilic chain segments in the amphipathic block polyether modified organosilicon, the graded distribution of the amphipathic block polyether modified organosilicon in the radial cross section of the membrane yarn is accurately controlled, and water increment speed difference at different parts can be realized, so that the hollow fiber membrane with the gradient hole structure is prepared; as a very strong hydrophobic interaction is formed between the hydrophobic parts of the amphipathic block polyether modified organosilicon and the polymer material, the hydrophily attenuation is avoided; according to the invention, the membrane hole structure of the hollow fiber membrane can be accurately controlled, the super / microfiltration water treatment membrane with super strength, super hydrophilia, ultra-low pressure or zero membrane pressure, ultrahigh water flux and ultrahigh antifouling property is obtained, the adjustment and control range is high, and the technology is simple.

The invention relates to the technical field of water pumps, in particular to an efficient submersible pump. The efficient submersible pump comprises a first parent, second parents, daughters, an endcover, a motor, a motor sealing box and a controller; the motor is used for providing power to the first parent; the first parent is used for transferring power of the motor to two daughters connectedwith the first parent and the second parents; one ends of the second parents are connected with the first parent, and the other ends of the second parents are connected with the end cover; two sidesof the second parents are connected with the daughters; two adjacent second parents are serially connected through clamping groove structures and couplings; at least two second parents are provided; the daughters are used for absorbing external water into the first parent and the second parents; and a water outlet pipe is arranged on the first parent. The serial connecting number of the second parents can be increased through a clamping mode to increase the length of the submersible pump, so that the use environment of synchronously pumping water in multiple pits of a pond is met, and the pumped water quantity can be increased.

The invention provides an anti-splashing device and an air conditioner. The anti-splashing device comprises a water collecting plate assembly. The water collecting plate assembly comprises a bearing plate and a surrounding plate arranged on the bearing plate. A supporting plate is arranged on the bearing plate. A water collecting tank is formed between the supporting plate and the surrounding plate. The anti-splashing device further comprises a water blocking structure. The water blocking structure surrounds the water collecting plate assembly. According to the anti-splashing device, the waterblocking structure is newly added to the periphery of the water collecting plate assembly. Through the depositing effect of airflow and the blocking effect of the water blocking structure, the splashing phenomenon caused when accumulated water in the water collecting tank is splashed is effectively avoided. The normal use environment is met, the failure problem is avoided, and the poor experienceof a user caused by the splashing phenomenon is avoided.
