The application discloses a material changing mechanism of a beveler, which comprises a mounting frame, a beveling assembly arranged on the surface of the mounting frame, the beveling assembly being used for beveling plate materials, a weighing assembly arranged on the lower side wall of the mounting frame, a placing plate arranged in the mounting frame through the weighing assembly, a U-shaped plate fixedly arranged on the side of the placing plate, and a storage box fixedly arranged between the opposite surfaces of the U-shaped plate. The beveling assembly drives the backward movement of a material changing plate in the material changing assembly. When the beveling assembly is separated, the beveling assembly drives the forward movement of the material changing plate in the material changing assembly, so that the material changing plate pushes the plate materials without beveling into the lower mold. The beveling assembly continuously bevels the plate materials, so that the material changing assembly continuously drives the plate materials into the beveling assembly and pushes the plate materials formed in the beveling assembly out, thereby avoiding manual feeding and discharging of the beveler, and making the beveler more convenient to use.

The utility model relates to a kind of automatic start-stop sewage submersible pump of drainage equipment technical field, comprising: buoyancy tank, it is fixedly installed on the inner wall of pit, the bottom of buoyancy tank is equipped with water inlet hole, slidingly connected with buoyancy block in buoyancy tank, the edge of buoyancy block lower surface is fixedly connected with scraper, and the end of scraper away from buoyancy block is contacted with the inner wall of buoyancy tank;Water pump, it is installed in pit, and the water outlet of water pump is communicated with water guide pipe, and the water outlet end of water guide pipe extends to drainpipe;Control mechanism, it includes controller and two liquid level sensors, two liquid level sensors are electrically connected with controller, two liquid level sensors are respectively arranged in the upper portion and lower portion of the inner wall of buoyancy tank, and the detection surface of liquid level sensor and the inner wall of buoyancy tank are on the same vertical plane;The water pump is electrically connected with controller. The present scheme is used to solve the problem that the current automatic drainage device may cause the failure of drainage system due to the solidification of slurry in accumulated water.

The invention relates to the field of low-temperature shield pumps, in particular to a low-temperature shield pump bearing supporting structure and a low-temperature shield pump. The shield pump comprises a pump shell, a stator and a rotor, and the rotor is supported through bearings arranged at the two ends of the stator. The bearing on at least one side comprises a bearing support fixedly arranged on the stator and a sliding bearing installed in the bearing support. A mounting surface for mounting the sliding bearing is arranged on the bearing support, the mounting surface is a concave spherical surface, and the outer surface of the sliding bearing is a convex spherical surface matched with the concave spherical surface, so that a spherical matching structure is formed, and the angle of the sliding bearing can be adjusted relative to the bearing support within a limited range. By means of the structure, when the bearing support deforms under the low-temperature working condition, the sliding bearing can be kept coaxial with the axis of the rotor through posture self-adaption adjustment, and abnormal abrasion or failure of the bearing caused by axis deflection is avoided.

This application discloses a control system, control method, storage medium, and vehicle for a vehicle steering motor, belonging to the field of vehicle control technology. The control system includes a first control device and a second control device connected to the first control device. The first and second control devices are respectively connected to the vehicle steering motor. When at least one of the first and second control devices fails, the vehicle steering motor is driven by the control device with the lower fault level. Thus, even if some system components fail, the motor can still be effectively controlled, avoiding the situation where the entire control system cannot work due to the failure of some system components. This improves the fault tolerance and reliability of motor control, and enables fine-grained control and management of the motor according to different fault conditions, with high flexibility.

The application discloses a power distribution network source and load regulation method, device and equipment and medium in a weak measurement environment, and belongs to the field of power distribution network source and load scheduling. The method is: acquiring the node importance and node measurement data of the power distribution network respectively, constructing a complete data set by using the node measurement data and determining a power distribution network source and load scene, wherein the complete data set is complete measurement information containing all observation nodes of the power distribution network; dividing the complete data set into a plurality of hierarchical training subsets according to the node importance and the power distribution network source and load scene; calculating a missing measurement parameter by using the hierarchical training subsets and determining a safety constraint index by using the node measurement data; performing progressive training according to the missing measurement parameter, the safety constraint index and the hierarchical training subsets to obtain a weak measurement environment regulation model; and calling the weak measurement environment regulation model to perform power distribution network source and load regulation processing. The application can call the model to perform power distribution network source and load regulation in a weak measurement environment, and improves the regulation precision.
