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 application provides a pipeline detection system, belonging to the pipeline detection field, and the system comprises a sensor construction device, a signal generator and a data acquisition instrument, the sensor construction device is used for importing pipeline basic parameters and a plurality of sensor parameters, and an electromagnetic simulation model is constructed; the pipeline basic parameters, the electromagnetic simulation model and the plurality of sensor parameters are used to select a sensor meeting the requirements; the sensor is arranged in a pipeline to be detected, and is electrically connected with the signal generator and the data acquisition instrument respectively; and the signal generator is used for generating an alternating excitation signal. The application can improve the accuracy of a detection result, does not need to be in direct contact with a pipeline wall, has relatively strong lift-off capability, does not have a component such as a steel brush affecting passability in structure, has relatively strong equipment deformation capability, has consistent sensitivity to defects of an inner wall and an outer wall of the pipeline, and can be suitable for pipelines on which a conventional inner detector cannot operate.

The utility model relates to a drilling rod grabbing manipulator, and belongs to the technical field of coal mine automatic drilling equipment. The manipulator is mainly composed of a fixing mechanism, a horizontal displacement mechanism, a lifting joint, an overturning joint, a telescopic joint and a gripper joint. The fixing mechanism is connected with the moving platform through connecting points arranged at intervals, the horizontal displacement mechanism achieves accurate horizontal movement through a linear guide assembly, and all joints work cooperatively through modular design. The mechanical arm is characterized in that the mechanical arm and the drill rod box are completely separated, the drill rod box can be independently and rapidly replaced, and the mechanical arm does not need to be adjusted. By means of the design, the adaptability of equipment to drill rods of different specifications is remarkably improved, the drill rod replacement process is simplified, meanwhile, the stability of the mechanical arm under the heavy load working condition is enhanced, accurate control over drill rod grabbing, lifting, overturning and conveying is achieved, and the mechanical arm is suitable for large-specification drill rod loading and unloading operation of a high-power directional drilling machine. The device has the technical advantages of compact structure, convenient operation and high reliability.
