This utility model discloses a bathtub with a built-in shelf. A seat is provided on the side wall of the water storage chamber, and a shelf is located within the water storage chamber. The shelf includes a support pipe and a shelf panel. A water pump is included, with its inlet connected to the water storage chamber and its outlet connected to the support pipe. Multiple circumferentially arranged lateral water jets are located on the upper end of the support pipe, each facing the side edge of the shelf panel. A guide ring extends downwards from the side edge of the shelf panel to guide the water flow. In use, the water pump draws water from the water storage chamber and pumps it into the support pipe. The water flows upwards along the support pipe and is then sprayed laterally from the multiple circumferentially arranged water jets at its upper end. The water sprayed laterally from the water jets diffuses along the bottom wall of the shelf panel towards its side edge, and finally flows downwards under the action of the guide ring, thus forming a surrounding water curtain landscape around the shelf panel. This bathtub shelf not only has basic storage functions but also serves as a scenic feature, significantly enhancing the user experience.

The invention discloses a large-size section pipeline installation auxiliary device and a using method thereof. The large-size section pipeline installation auxiliary device comprises an equipment base, a lifting assembly, a lifting base, an angle adjusting base and a pipeline containing device. A lifting assembly is installed on the equipment base, the lifting base is movably connected with the lifting assembly and can ascend and descend under the action of the lifting assembly, the lifting base is horizontally arranged, an angle adjusting base is installed on the lifting base, and one side of the lifting base is connected with the angle adjusting base through a rotating pair. An angle adjusting device acting in the vertical direction is installed on the other side of the lifting base, the end, away from the lifting base, of the angle adjusting device is fixed to an angle adjusting base, and a pipeline containing device used for containing a pipeline is fixed to the angle adjusting base. The auxiliary device for installing the large-size section pipeline is reasonable in structural design, capable of completing efficient and safe installation of the pipeline without cooperation of hoisting equipment, good in adaptability, flexible to operate, high in adjusting precision and good in application prospect.
