The invention discloses a multifunctional nursing bed which comprises an opening and closing bed with the surface capable of being opened and a sunken bed changing assembly capable of controlling the opening and closing degree of the opening and closing bed. By means of the sinking type bed changing assembly, when bed changing needs to be conducted on a bedridden person or a sickbed needs to be cleaned, an opening and closing control part can control an opening and closing plate to be gradually opened, a linkage bag gradually puts the bedridden person to the surface of an auxiliary bed from an opened passing opening, at the moment, the linkage bag is separated from a connecting rope, and then the bed can be changed. The auxiliary bed can smoothly take out a patient from the lower portion of the bed body, a single person can quickly and safely complete bed changing work of the patient, meanwhile, the opening and closing plate can achieve the turning-over function of a bedridden person together with the linkage bag under the control of the opening and closing control part, and in the process of using the massage mattress, the opening and closing plate and the linkage bag can achieve the turning-over function of the bedridden person together through the air purification assembly. The function of purifying air on the surface of the bed body is achieved, fresh air moves towards the bed head, and the workload of nursing staff is effectively reduced.

This invention discloses an integrated braking and grounding device for a semi-direct-drive wind turbine, comprising a motor brake disc and a grounding slip ring. The motor brake disc and the grounding slip ring are detachably connected as one unit in the axial direction via a stop and bolts to shorten the axial space. Simultaneously, the axial cross-section of the grounding slip ring is an "L-shaped" structure, consisting of an outer friction ring and an inner mounting plate made of different materials, to significantly reduce costs. Furthermore, this invention installs a speed sensor on the motor brake disc and machines its outer circumference into a gear shape to achieve single-blade turning function. This invention fully utilizes the space at the rear end of the motor by axially integrating the motor brake disc and the grounding slip ring, and significantly reduces manufacturing costs while maintaining performance by changing the material of the grounding slip ring.

The present application relates to the technical field of fire-fighting maintenance, and particularly relates to an automatic jigger device and method for a fire-fighting water pump, which comprises a mounting unit, the mounting unit comprising a fixed pipe and a mounting box, a switch valve arranged on the fixed pipe, a connecting assembly arranged between the fixed pipe and the mounting box, and a drain pipe arranged at the bottom of the mounting box; and a jigger unit, the jigger unit comprising a rotating shaft rotatably arranged in the mounting box, a fixing assembly arranged in the rotating shaft, and a plurality of blades arranged on the rotating shaft; the connecting assembly is matched with the blades. The automatic jigger device and method for the fire-fighting water pump, by fixing and welding the fixed pipe with the outlet main pipe network of the fire-fighting water pump, high-pressure water in the main pipe network is used to impact the blades through the connecting assembly to drive the rotating shaft to rotate, the fixing assembly is connected with the driving pump shaft of the fire-fighting water pump to drive the driving pump shaft to rotate, and the jigger function is realized.

The invention relates to the technical field of microbial fertilizer manufacturing equipment, in particular to a device for a microbial organic fertilizer manufacturing technology, which solves the problem of low production efficiency caused by poor working connectivity among a plurality of equipment products for fertilizer fermentation, and comprises a main fermentation box, an after-ripening box, a screen and a discharge rotating plate positioned below the screen, the upper end and the lower end of the main fermentation box are both of an open structure, the after-ripening box is fixedly connected to the lower end of the main fermentation box, the upper end of the after-ripening box is of an open structure, an upper opening of the after-ripening box is communicated with a lower opening of the main fermentation box, a discharging channel is arranged on the side face of the after-ripening box, and outer supports are fixedly connected into the after-ripening box in a linear array mode. According to the machine disclosed by the invention, a main fermentation process, a block screening process, a discharging process and an after-ripening process can be carried out on a fertilizer, a pile turning function is correspondingly carried out, and the working connectivity between the main fermentation box and the after-ripening box is relatively high, so that the production efficiency is relatively high.
