The present invention discloses a sleeping cabin with a monitoring function, which relates to the field of brain health, including a sleeping cabin, a signal transmitter is fixedly connected to the upper surface of the sleeping cabin, a cabin door is hinged at the front surface of the sleeping cabin, the lower end of the inner surface of the sleeping cabin is fixedly connected to a bed body, a wire harness collecting device is arranged at the upper end of the inner surface of the sleeping cabin, and a wire harness adjusting device is arranged inside the wire harness collecting device. When the present invention is in use, the user is required to push the electroencephalogram sensor upward as a whole after use, at which time the placement seat will form adsorption with the magnetic metal on the upper surface of the electroencephalogram sensor below through the magnet inside the groove, and at the same time, the groove on the side surface of the placement seat can be opened by independently rotating the baffle, at which time an independent electrode sheet can be placed inside the groove, thereby avoiding the risk of entanglement and damage caused by the natural drooping of the electrode sheet and the electroencephalogram sensor cable.

The utility model discloses an impeller and power cavity structure of an energy-saving water pump, which relates to the field of water pumps and comprises an impeller body, an arc-shaped surface is arranged at one end of the impeller body, a plurality of large blades and small blades are arranged on the outer side of the arc-shaped surface at equal intervals, the small blades and the large blades are alternately arranged, two pressure relief holes are formed in each large blade in a penetrating manner, and the pressure relief holes are communicated with the arc-shaped surface. Through the arrangement of the pressure reducing holes, part of liquid can naturally flow along with the vortex phenomenon after passing through the pressure reducing holes, the conveying efficiency of the liquid is guaranteed, meanwhile, the load of the large blades is reduced, then the load of the driving motor is reduced, and the service life of the driving motor is prolonged. And the liquid passing through the pressure reducing holes can be in contact with the small blades and the corresponding large blades to push the passing liquid, so that the load is reduced, and meanwhile, the conveying of the liquid is ensured.

This invention relates to the field of rock and soil exploration technology, and discloses a rock and soil drilling exploration device for engineering construction. The device includes a main body with a support frame rotatably connected inside. A drill rod is mounted on the side wall of the support frame. When two arc-shaped plates form a cross shape around the outer surface of the drill rod, the invention enhances the rotational force of the motor, causing the motor to drive the drill rod to rotate and disengage from a jammed state via a threaded shaft. After disengagement, the hydraulic rod retracts to its output end. As the hydraulic rod retracts, it resets the two arc-shaped plates, allowing them to fit onto the outer surface of the drill rod, enabling normal operation. This reduces the likelihood of the drill rod jamming when encountering harder rock layers during rotation within the rock and soil strata, thus improving the exploration quality of the device.

The utility model relates to the field of lithium battery diaphragms, and discloses a liquid scraping device which comprises a speed reducing motor, a coupler, a liquid scraping roller, two first bearing seats, two linear moving mechanisms and two support plates, the speed reducing motor drives the liquid scraping roller to rotate through the coupler; the two ends of the liquid scraping roller penetrate through the first bearing seats correspondingly, and the first bearing seats rotationally support the liquid scraping roller through bearings. Each support plate is provided with a linear moving mechanism, and the two linear moving mechanisms drive the bearing seats to move and drive the liquid scraping rollers to be away from or close to the thin film. According to the liquid scraping roller, the rotating function is added, and the technical problems that a traditional liquid scraping roller is unpowered, and precipitates can be generated on the surface of the roller after long-time use are solved. Precipitates cannot be attached to the surface of the thin film, and the quality of the thin film is improved.

This utility model relates to the technical field of paper feeding and processing, and discloses an adjustable pressure feeding mechanism for an automatic feeding flatbed machine. It includes two parallel supports, with an adjusting rod between the lower parts of the supports. A sleeve is provided on one side of each support facing each other, and a connecting shaft is provided on one side of each sleeve. The connecting shaft passes through the supports and has an adjusting structure at its end for adjusting the rotational resistance of the sleeve. This utility model adjusts the rotational resistance of the connecting shaft through the adjusting structure, thereby adjusting the rotational speed of the sleeve. The adjusting structure works by rotating a threaded sleeve, which, through a compression spring, presses against a compression sleeve, causing the compression sleeve to abut against a fixed seat. This increases the resistance of the sleeve, reducing the power transmitted to the connecting shaft, thus limiting the rotational speed of the sleeve and preventing stacking.
