The present application relates to the technical field of coal mine underground transportation equipment, and particularly relates to a fully mechanized coal mining face crossheading single rail train system and advancing method, wherein the fully mechanized coal mining face crossheading single rail train system comprises a trailer, a train set and a pipe cable telescopic device connected in sequence, the tail of the pipe cable telescopic device is connected with a reversed loader, a track is laid under the train set, the train set travels along the track, the trailer is connected with the track through a cross connector and drags the track to advance; the advancing method comprises the steps of pulling and moving the track, pulling and moving the train set, advancing the working face and cyclically advancing. The present application realizes the rapid and continuous movement of the train through the long-distance alternate movement of the track and the train, without the need of frequently disassembling and laying tracks and the need of winch steel wire rope traction, can effectively reduce the labor intensity and operation time of workers and improve the safety of train operation.

This utility model discloses a lifting device for PT connecting sleeves, relating to the field of installation equipment technology. The lifting device for PT connecting sleeves includes a base and a hanger located in the middle of the top surface of the base. It also includes a slider slidably connected to the top left side of the hanger, with a fixing mechanism fixedly connected to the bottom of the slider. Through the fixing mechanism, when the device is to be used, the external PT connecting sleeve is first passed through a suspension rope, and then secured using the rope loops and fixing buckles inside the suspension rope. Next, the lifting hydraulic rod is raised, allowing the sleeve to rise with the fixing plate for further transportation. This facilitates the securing and lifting of the connecting sleeve during transportation, preventing tilting and detachment during transport due to inadequate or insufficient securing, which reduces transportation efficiency and increases the damage rate of the connecting sleeve.

The utility model relates to the technical field of sewage filtering, and discloses a textile sewage filtering device which comprises a filtering tank, a water outlet is formed in one end of the filtering tank in a penetrating mode, the other end of the filtering tank is connected with a transmission mechanism, and the output end of the transmission mechanism penetrates into the filtering tank and is connected with a filtering assembly. The other end of the filtering assembly is connected with the water outlet, and the outer portion of the filtering assembly is connected with a hair collecting assembly. According to the textile sewage filtering device, the transmission mechanism, the filtering assembly and the hair collecting assembly are arranged in the filtering tank, so that when textile sewage is coarsely filtered through the filtering tank, the transmission mechanism can drive the filtering assembly and the hair collecting assembly to rotate together; sewage in the filter tank can be actively hooked through rotation of the hair collecting assembly, so that the filtering effect is improved.

The embodiment of the invention discloses a new energy grid-connected harmonic suppression regulation and control method and device, electronic equipment and a medium. A specific embodiment of the method comprises the following steps: performing variable window Fourier transform on a power instantaneous value sequence set, and then performing impedance compensation to obtain a compensated power harmonic spectrum diagram set; performing critical point identification on the new energy grid-connected power region to obtain a harmonic resonance critical point set; performing early warning grade division on the harmonic resonance critical point set to obtain an early warning grade critical point set; performing harmonic time sequence prediction on the compensated power harmonic spectrogram and the inverter power information to obtain a harmonic prediction amplitude oscillogram; and performing harmonic suppression control on the early warning grade critical point to obtain grid-connected harmonic regulation and control information, and performing equipment regulation and control processing on the power equipment. According to the embodiment, the early warning accuracy of the harmonic resonance risk and the efficiency of suppressing the harmonic resonance can be improved, the equipment delay is reduced, the safety of the new energy grid-connected equipment is improved, and the power loss is reduced.

The utility model relates to the technical field of building construction, in particular to an ALC light partition wall used in a modular building and a building module with the ALC light partition wall. The partition wall comprises a plurality of partition wall bodies which are sequentially connected, a grouting space used for grouting is arranged at the joint of every two adjacent partition wall bodies, and grouting materials used for connecting every two adjacent partition wall bodies can be poured into the grouting spaces; the grouting space is formed by a grouting through groove formed in the side wall of the partition wall body in the vertical direction; chamfers are arranged at the four corners of the partition wall body. According to the ALC light partition wall, the grouting space is formed between the adjacent partition wall bodies, and the grouting material is used for filling and fixing, so that the structural strength and stability of the ALC light partition wall are effectively improved, the displacement or damage risk caused by external factors is reduced, and joint cracking caused by inertia force in the transportation process of the ALC light partition wall and the dead weight of modules in the hoisting process is avoided; and the overall quality of the modular building is improved.
