The invention relates to the technical field of livestock breeding equipment, and discloses a breeding auxiliary frame for livestock cattle and sheep, the breeding auxiliary frame comprises a rack, and vertical fences are fixedly assembled on the outer walls of the two sides of the rack; two limiting mechanisms are arranged at the position, located between the two vertical bars, of the top of the rack. Each limiting mechanism comprises a transverse guide rail, two sliding frames slidably connected to the transverse guide rail in a sleeving mode and a lifting bottom plate arranged on the inner wall of the sliding frame. Side clamping plates are arranged on the opposite surfaces of the two groups of sliding frames; the inner wall of the top of the lifting bottom plate is slidably sleeved with a breeding stock pedal. By arranging the breeding stock pedal, during mating, the weight of the breeding stock is independently borne by the breeding stock pedal and transmitted to the rack through the lifting bottom plate and the sliding frame, direct transmission of the weight of the breeding stock to the female stock is thoroughly blocked, it is ensured that the female stock can stably stand for a long time, and the risk that the back of the female stock is injured in the artificial auxiliary breeding process is effectively eliminated.

This invention discloses a method for controlling the main steam temperature of an ultra-supercritical unit. An extraction valve is added to the extraction steam pipeline of the high-pressure heater to achieve precise extraction steam throttling adjustment. Thermodynamic parameters of the boiler and turbine systems are collected and cleaned. The feedwater heating insufficiency and reheat steam flow rate changes corresponding to the unit extraction steam throttling flow rate under different high-pressure heater extraction steam throttling schemes are calculated. Furthermore, the heat absorption changes of the economizer and part of the superheater heating surfaces after the reheater are calculated. Finally, the predicted value of the main steam temperature change corresponding to the unit extraction steam throttling flow rate under different high-pressure heater extraction steam throttling schemes is obtained. Based on the real-time deviation of the main steam temperature, the high-pressure heater extraction steam throttling scheme and the required extraction steam throttling flow rate are selected. By adjusting the extraction steam throttling flow rate of each high-pressure heater, more precise control of the main steam temperature is achieved, alleviating the problem of main steam overheating that easily occurs during rapid load increases. This is of great significance for improving the operational flexibility of ultra-supercritical units.

The utility model discloses a bathtub fixing structure and a bathtub. The bathtub fixing structure comprises a connecting piece and a fixing piece. The fixing piece is suitable for being installed on the ground and provided with a face cover and a containing groove, and the face cover extends in the first direction. A first notch of the accommodating groove faces a first direction, and the side wall of the accommodating groove extends along a second direction and is connected with the surface cover; the connecting piece is provided with an abutting surface, the connecting piece is suitable for being inserted into the containing groove from the first notch in the first direction so as to be fixedly connected with the fixing piece, and the abutting surface is matched with the surface cover in an abutting mode; the connecting piece is suitable for being fixedly connected with the bathtub in the second direction. By adopting the fixing structure, compared with the prior art, the bathtub can be fixedly mounted by translating the bathtub to fix the connecting piece in the accommodating groove no matter whether the bathtub has or is provided with a skirt edge, or is provided with a split skirt edge or an integrated skirt edge, so that the bathtub is relatively labor-saving and convenient.
