The utility model discloses wireless access equipment, and relates to the technical field of wireless access equipment. The device comprises a shell, a sealing assembly is arranged in the shell, a mounting groove is formed in the shell, and a driving assembly is rotationally connected into the mounting groove. The driving assembly is rotated to drive the clamping assembly to move in the opposite direction, so that clamping of the clamping assembly is relieved, the sealing assembly is pulled to move, the sealing assembly moves in the shell and is separated from the interior of the shell, and then the sealing assembly is disassembled. When the wireless access equipment needs to be installed, the sealing assembly is inserted into the shell to drive the clamping assembly to move, and then the reset assembly is matched to drive the clamping assembly to complete clamping, so that the wireless access equipment is convenient to disassemble and install; and thus, the detection and maintenance efficiency of the wireless access equipment is improved.

The invention provides railway track fastener state detecting and fastening equipment. Comprising a working vehicle, a power system, a fastener cleaning device, a bolt fastening device, a telescopic pressing strip device, a sensor system, a data collecting and processing device, a control system, a data storage device and the like. The fastener cleaning device is used for cleaning a fastener bolt and an elastic strip. The data collecting and processing device obtains fastener state information through machine vision, and a convolutional neural network model is used for training and predicting the friction coefficient of a fastener bolt and a friction wheel in the bolt fastening device and obtaining the relative position relation between the fastener bolt and the fastener. The telescopic pressing strip device is used for reducing the torque required for fastening a bolt through a telescopic elastic strip; and the bolt fastening device is used for controlling and applying the bolt fastening torque by adjusting the distance between a friction wheel and a rolling wheel. Therefore, the state detection of the railway track fastener and the automatic fastening of the fastener are realized, and the manual and field operation procedures required by on-site fastener state detection and fastener fastening are greatly reduced.

This application provides a railway bridge health monitoring system and method based on infrared thermal imaging. The data acquisition device uploads the collected monitoring data to the monitoring center via a local monitoring module. The monitoring center sets a disease alarm threshold; if the difference between the average temperature of the monitored area and the ambient temperature exceeds the alarm threshold, it is determined that there is a potential disease in the monitored area. Then, sensor data from the monitored area is acquired to determine the type of disease, and the disease level is determined based on the bridge temperature data in the monitored area. An alarm is issued and a handling plan is displayed. Simultaneously, the monitoring center performs machine learning on the monitoring data to predict potential disease risks, issue early warnings, and display handling strategies. The technical solution provided in this application comprehensively analyzes the bridge temperature data acquired by the infrared thermal imaging camera and the sensor data acquired by the sensors to determine the type and level of disease and display handling plans, thereby improving the efficiency of detection and maintenance.

The invention belongs to the technical field of power grid maintenance, and discloses an auxiliary fixing device which comprises a wearing assembly, an adjusting assembly, a fixing assembly and a balancing assembly. The wearing assembly is used for being detachably fixed to a human body; the adjusting assembly comprises a first telescopic piece and a second telescopic piece which are matched to adjust the position of the end of the second telescopic piece in a damping mode. The fixing assembly is arranged at the end of the second telescopic piece and used for fixing detection equipment. The balance assembly comprises a motion conversion mechanism and a balance weight piece, and the motion conversion mechanism can drive the balance weight piece to move in the direction opposite to the motion direction of the first telescopic piece under the action of the first telescopic piece. By using the auxiliary fixing device, an operator does not need to continuously hold the detection equipment and arrange the detection equipment at a proper position in the repair and maintenance process of the intelligent distribution network through the adjusting assembly and the fixing assembly, so that the efficiency of detection and maintenance is improved; and the stability and the operation experience of the auxiliary fixing device during use are improved through the balance assembly.
