The application relates to a bearing damage positioning method based on Lamb wave dispersion mode matching of acoustic emission signals, wherein different frequency band components of original acoustic emission signals with the same frequency interval are obtained; a time of arrival curve is obtained; a theoretical dispersion curve of Lamb wave propagation in a bearing is solved, then a coordinate system is unified with the signal time of arrival curve; the dispersion curve and the time curve are matched through a Pearson correlation coefficient index; a formula is established according to a speed difference and a time difference, and a bearing damage distance is calculated; the sensor is moved by a certain distance to be measured again, and the damage position is determined through the two results. The method of matching the Lamb wave propagation mode can determine the propagation speed of the acoustic emission signals with different frequencies, the accuracy of the time difference positioning method is greatly improved, the bearing damage position can be directly found through a single sensor, the bearing fault diagnosis can be realized without depending on the bearing rotating speed, the installation difficulty can be effectively reduced, and the detection cost can be reduced.

The utility model discloses a multi-angle adjustable automatic locking connector which comprises a first connecting pipe, a second connecting pipe, a third connecting pipe and two groups of limiting mechanisms, wherein the first connecting pipe, the second connecting pipe and the third connecting pipe are axially connected in series. The top ends and the bottom ends of the connecting pipes are provided with inserting parts with anti-skid lines, the tops of the second connecting pipe and the third connecting pipe are provided with vertically-crossed penetrating type assembling grooves, and the bottom ends of the first connecting pipe and the second connecting pipe are provided with tooth-shaped assembling heads meshed with the first connecting pipe and the second connecting pipe. The limiting mechanism is composed of a buckle assembly, a button assembly and a spring reset system, the buckle assembly is engaged with the assembling head through a locking tooth groove to achieve locking, and unlocking is completed through cooperation of the button assembly and the spring reset system. In addition, a long screw is arranged between the assembling groove and the assembling head for fastening, the button assembly is provided with a guide boss, and the inserting part is provided with a sealing groove. According to the connector, multi-angle flexible adjustment can be realized, and the requirements of complex scenes are met; the automatic locking function is combined with the long screw to ensure stable and reliable connection; and the structure is compact, operation is convenient and fast, the installation efficiency and the equipment operation safety are effectively improved, and the wide application value is achieved.

The utility model provides an expandable fastening fitting for electric power engineering construction, which comprises a fastening plate and side lugs, the fastening plate is of a U-shaped structure, the two ends of the fastening plate are fixedly connected with the side lugs, the middle part of the fastening plate is hollow, the top surface and the bottom surface of the fastening plate are fixedly connected with insulators, and the side lugs are provided with positioning holes. The utility model has the advantages that the fitting capable of expanding and shrinking inside and outside has stronger adaptation performance and better use flexibility, the problem of difficult installation caused by size mismatching is reduced, the safe clamping of a cable is ensured by a stable locking mechanism and a flexible adjusting design, and the service life of the cable is prolonged. And the risk caused by improper installation or cable looseness is reduced, and hardware fittings with different sizes do not need to be customized for different installation environments, so that the production and purchase costs are saved. No matter in a preparation stage before installation or in an adjustment stage in the installation process, the fitting shows high flexibility, so that an operator can perform rapid and accurate adjustment according to actual conditions.

This invention discloses an automatic backwashing filtration device with a dual centrifugal and dual-net structure, including a water storage cylinder with a second connecting pipe fixedly connected to it. This invention employs an innovative architecture of centrifugal sedimentation + dual-net graded filtration: high-speed rotation inside the filter cylinder generates centrifugal force to separate large particles such as silt and organic matter from the water; the double-layer stainless steel filter inside the filter cylinder precisely intercepts suspended solids, adapting to different water qualities; the operation of the first and second cylinders respectively drives the movement of the first and second support columns, thereby adjusting the height of the water storage cylinder and providing flexibility for different installation scenarios; the first sliding plate slides into the groove of the second sliding plate, and the first connecting plate and the enclosed cavity form a closed space, preventing the second solenoid valve from being affected by environmental dust, moisture, or electromagnetic interference, avoiding abnormal control signals, and improving the stability and reliability of the equipment operation.
