The invention relates to a lower animal breeding device, particularly to a lower animal breeding device having an inflating influent switching function, comprising a cabinet arranged with drain air holes, a breeding carrier is arranged in the cabinet, an inflating and intake conduit switching device is arranged in the breeding carrier of the cabinet, comprising a central main conduit arranged vertically, a gas tube and a gas inlet pipe are arranged on top of the central main conduit, two-five tapping points are arranged on the central main conduit; a branch pipe is respectively connected on two sides of the main conduit of each tapping point; a secondary branch pipe is respectively connected on two sides of the end of the branch on the second or the third tapping point; a small hole of 0.5-1.5 mm is arranged every 3-5 cm on the conduit wall of the branch pipe and the secondary branch pipe. The invention releases air bubbles and water vapor up and down, backwards and forwards, left and right in turn in the middle of the solid breeding carrier, evenly keeps carrier breeding humidity and ventilation which is suitable for breeding bloodsuckers.

The invention discloses a single and double mounting point device for a cross arm of a steel pipe pole. The single and double mounting point device comprises the cross arm, a single-mounting point suspension plate I, a single-mounting point suspension plate II and double-mounting point suspension plates, wherein the single-mounting point suspension plate I and the single-mounting point suspension plate II are arranged at the front end of the cross arm; the double-mounting point suspension plates are respectively connected with the lower parts of the single-mounting point suspension plate I and the single-mounting point suspension plate II; the single-mounting point suspension plate I is parallel to the single-mounting point suspension plate II; and the single-mounting point suspension plate II is arranged behind the single-mounting point suspension plate I in the length direction of the cross arm. The single and double mounting point device has the beneficial effects that the single and double mounting point device is attractive in appearance, flexible and convenient; lead suspension plates are movably connected; the appearance is attractive; the problem that double suspension plates which are relatively large and relatively bulky in appearance are adopted when single-mounting point connection is required is avoided; standardization of the cross arm is facilitated; the lead suspension plates are movably connected; the form of the cross arm can be reduced; the standardization of the cross arm is facilitated; and installation, marking, construction and the like are facilitated.

This invention is to resolve the question that the heat exchanging efficiency of existing heating radiator is low. It is a air exchanging radiator, which has body case and fluid channel inside of the body case. Heating fluid channel and heated air channel, which are separated by conductor, are arranged inside of the body case. The air channel has fan and joint with fan. The air in the heated air channel flows to exchange heat. The air is driven by the fan. It greatly increases the effect of heat exchanging and heating. It increases the heat efficiency.

The invention relates to a 1000 MW reactor coolant pump lifting hook conversion device. The device is characterized in that plug pins penetrate into holes in the upper portion of a conversion seat, cargo booms are arranged on the plug pins, hexagonal head screws are matched with stop washers to penetrate through threaded holes in lock plates to be fixed with the plug pins, the hexagonal head screws are matched with hexagonal head nuts to penetrate through the threaded holes in the lock plates to be fixed with the cargo booms, guide sleeves are connected with the cargo booms through the hexagonhead screws and the lock washers, small shafts penetrate into the guide sleeves, and moving rods are arranged in threaded holes of the small shafts. By applying the device, the rapid conversion use of a 1000 MW reactor coolant pump lifting hook can be achieved, the controllability is high, the required manpower is less, the operation is simple, and mounting and dismounting are convenient; and thedevice is convenient to manufacture and is beneficial to saving the cost.
