Description

Technical Field

[0001] This utility model relates to the field of fans for railway locomotives. Background Technology

[0002] During operation, ventilation fans may vibrate due to mechanical wear, imbalance, loosening, and other reasons. Prolonged vibration not only affects the performance of the fan but can also lead to serious safety accidents. Simultaneously, the temperature inside the fan or in the surrounding environment can fluctuate due to various factors, potentially causing equipment failure due to overheating. Therefore, installing vibration and temperature detection devices to monitor the fan's vibration status in real time plays a crucial role in preventing malfunctions and improving equipment reliability and safety. Providing data support for equipment operation and optimizing ventilation not only improves the fan's operating efficiency and reliability but also provides essential data support for equipment maintenance and management. However, there are shortcomings in the intelligent health diagnosis of ventilation fan units used in rail transit locomotives; fan efficiency is low due to installation space limitations; and the high noise generated by the fans is unfriendly to drivers, passengers, and the environment. Summary of the Invention

[0003] The technical problem solved by this utility model is to provide an intelligent and efficient ventilator that can monitor fan vibration and motor bearing temperature rise in real time, and intelligently diagnose the health status of the ventilation unit.

[0004] This utility model employs a smart and efficient ventilator, comprising a housing and a motor within the housing, as well as vibration and temperature sensors. Both the vibration and temperature sensors are mounted on the upper part of the ventilator motor at the fan head. A data acquisition box is also mounted on the housing, located at the lower outer end of the housing. Signals from the vibration and temperature sensors are transmitted to the data acquisition box via internal data cables. The bottom of the housing is a traction air duct, on which a wind speed sensor is installed; the wind speed sensor's signal is also transmitted to the data acquisition box.

[0005] The upper end of the motor is also equipped with a guide joint, which connects and fixes the internal data cable.

[0006] It also includes a connecting ring plate, which is installed on the outside of the housing to facilitate the installation of the ventilator.

[0007] It also includes a decorative panel, which is installed on the outside of the housing. Second mounting holes are provided at the four corners of the decorative panel for bolting the panel to the ventilator. Through slots are provided in the decorative panel for the ventilator's mounting structure to pass through.

[0008] The beneficial effects of this utility model are that it uses a health diagnosis system based on temperature, vibration and wind speed sensors to intelligently diagnose the operating health status of ventilation units during railway locomotive operation in real time, including the condition of the motor bearings, abnormal noise, and the judgment of ventilation air volume, thus solving the problem of failure to detect or diagnose faults in a timely manner during fan operation; at the same time, it optimizes the impeller structure and aerodynamic profile through finite element flow field analysis, and combined with soundproof decorative doors, it significantly reduces the noise generated by the ventilation fan during operation, thus improving environmental friendliness.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] The overall structure of the traction ventilation fan in this application is as follows: Figures 1-4 As shown, the term "fan" will be used as a shorthand for "traction ventilation fan" in the following text. The motor 25 is located inside the housing 1, with the impeller assembly 2 at the upper end and the air inlet assembly 19 at the upper end of the housing. Vibration sensors 36 and 35 are installed at the head section of the fan motor to monitor the vibration frequency and temperature in the horizontal (X), vertical (Y), and axial (Z) directions of the fan. Monitoring in these three directions allows for a more comprehensive assessment of the fan's operating status. Timely detection and handling of vibration anomalies prevent fan malfunctions and improve equipment safety.

[0018] A guide connector is also provided at the top of the motor to secure the internal data cable, preventing it from becoming loose and also making the internal structure of the housing neater. The wire connectors of the vibration sensor 36 and temperature sensor 35 are located on the same plane, with an angle between them between 10° and 20°. The angle between the oil pipe 40 connected to the bottom of the motor and the wire connector of the temperature sensor is 10° ± 1°. This arrangement makes the overall performance of the ventilation fan more balanced and more stable.

[0019] The traction air duct 112 is located at the bottom of the housing 1. A wind speed sensor 114 is installed on the traction air duct 112. All measured signals are transmitted to the data acquisition box 13 through an internal data line. The data acquisition box 13 is installed on the lower part of the housing 1 to avoid the influence of vibration and high temperature. The data acquisition box 13 is provided with 3 sets of plug-in pins, which are connected to vibration and temperature sensors. When more sensors are needed, the number of plug-in pins is increased accordingly.

[0020] The control system adjusts the fan's operating parameters, such as speed and airflow, based on temperature data to optimize ventilation or prevent overheating. In case of abnormal temperatures, the control system can issue an alarm to alert operators for maintenance or other measures. Fans with integrated temperature sensors enable intelligent management, improving equipment automation and reducing the cost of manual intervention.

[0021] A decorative door 11 is also connected to the outside of the housing 1. The decorative door 11 has the function of reducing noise. A second mounting hole 113 is opened at the four corners of the decorative door 11 to facilitate bolt connection with the ventilation fan.

[0022] The outer casing 1 is equipped with a connecting ring plate for easy connection and fixation of the fan. A through slot is provided for the fan's fixing structure to pass through. The fan can be wall-mounted, facilitating the installation and positioning of vibration and temperature sensors.

[0023] The fan described in this application can detect potential faults in a timely manner by monitoring the vibration and temperature status of the fan in real time. Adjusting the fan's operating parameters based on the monitored temperature can optimize ventilation and improve the equipment's efficiency. Furthermore, temperature monitoring can promptly detect overheating within the fan, preventing equipment failures caused by overheating and extending the equipment's service life.
