Description

Technical Field

[0001] This application relates to the field of locomotive maintenance and monitoring, and in particular to an HXD3CA type electric locomotive fan speed monitoring device. Background Technology

[0002] The HXD3CA electric locomotive is one of the main types of locomotives used for freight transport on main railway lines. The stable operation of its composite cooling system is crucial to the locomotive's power system. The composite cooler fan is responsible for forced air cooling of the cooling medium. If the fan malfunctions or its efficiency decreases, it can cause the main converter and main transformer to overheat, which may lead to a mechanical failure and affect train operation safety in severe cases.

[0003] Currently, routine monitoring of locomotive fan wind speed mainly relies on handheld anemometers. However, the composite cooler ducts of the HXD3CA locomotive, especially those located inside the locomotive and under the car, are compactly designed, structurally concealed, and extremely narrow in space, often obstructed by surrounding pipes and the car body structure. This leads to at least the following significant difficulties for traditional wind speed monitoring devices and manual handheld measurements: (1) Poor accessibility: It is difficult for measurement personnel to directly enter or approach the air duct outlet, especially the air duct under the vehicle is in a tricky position, and conventional anemometer probes cannot be stably extended or aligned.

[0004] (2) Unsafe operation: Maintenance personnel often have to crouch or bend over in the pit under the vehicle, which is unstable and poses safety risks such as bumps and slips. At the same time, the fan is under load when being measured, which poses a risk of injury from fan discharge.

[0005] (3) Large reading error: Due to space limitations and insufficient light, it is difficult to look at the anemometer screen, which can easily lead to reading errors; when measuring by hand, it is easy to shake, making it difficult to ensure that the probe is perpendicular to the wind direction, which affects the accuracy of the measurement.

[0006] Therefore, in the daily maintenance and condition monitoring of locomotives, there is an urgent need for a wind speed monitoring method that can adapt to narrow and concealed spaces and facilitate remote operation and reading, so as to improve measurement efficiency, data reliability and operational safety. Summary of the Invention

[0007] The purpose of this application is to provide an HXD3CA type electric locomotive fan speed monitoring device, which can improve measurement efficiency, data reliability and operational safety.

[0008] To achieve the above objectives, this application provides the following solution: In the first aspect, this application provides an HXD3CA type electric locomotive fan speed monitoring device, including: a support base, an angle adjustment-fixing unit, a measurement unit and a visual monitoring unit; The support base is used to mount the angle adjustment-fixing unit and the visual monitoring unit; the measuring unit is fixed on the angle adjustment-fixing unit; the measuring unit is electrically connected to the visual monitoring unit. The angle adjustment-fixing unit is used to adjust the angle and position of the measuring unit to align it with the air duct outlet of the HXD3CA electric locomotive fan; the measuring unit is used to detect the wind speed data at the air duct outlet of the HXD3CA electric locomotive fan. The visual monitoring unit is used to display wind speed data in real time.

[0009] According to the specific embodiments provided in this application, this application has the following technical effects: To address the difficulties in traditional wind speed measurement caused by the concealed location and confined space of the composite cooler duct in the HXD3CA electric locomotive, this application provides a wind speed monitoring device for the HXD3CA electric locomotive fan. By utilizing a support base, a stable measurement platform can be established in complex ground environments, improving the reliability of wind speed data measurement. The use of an angle adjustment-fixing unit allows for adjustment of the angle and position of the measuring unit, aligning it with the duct outlet, offering flexibility and adaptability. Through the combination of the support base, angle adjustment-fixing unit, measuring unit, and visual monitoring unit, wind speed data can be detected in real time, improving measurement efficiency and effectively enhancing the accuracy and safety of wind speed monitoring in confined spaces. This facilitates routine preventative maintenance and ensures safe locomotive operation. Attached Figure Description

[0010] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0011] Figure 1 This is a schematic diagram of the disassembled structure of an HXD3CA type electric locomotive fan speed monitoring device provided in an embodiment of this application.

[0012] Figure label: 1-Carbon fiber tube, 2-Camera, 3-Quick-connect kit, 4-Camera mounting device, 5-Flexible alloy rod, 6-Measuring unit, 7-Adjustable tripod, 8-Clamp. Detailed Implementation

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] In one exemplary embodiment, this application provides an HXD3CA type electric locomotive fan speed monitoring device, such as... Figure 1 As shown, the device includes: a support base, an angle adjustment and fixing unit, a measurement unit 6, and a visual monitoring unit.

[0016] The support base is used to mount the angle adjustment-fixing unit and the visual monitoring unit. The measuring unit 6 is fixed on the angle adjustment-fixing unit. The measuring unit 6 is electrically connected to the visual monitoring unit.

[0017] The angle adjustment and fixing unit is used to adjust the angle and position of the measuring unit 6 to align it with the air duct outlet of the HXD3CA electric locomotive's fan. The measuring unit 6 is used to detect the wind speed data at the air duct outlet of the HXD3CA electric locomotive's fan.

[0018] The visual monitoring unit is used to display wind speed data in real time.

[0019] In one exemplary embodiment of this application, to facilitate the stable extension of the measuring unit 6 to the target area, the HXD3CA type electric locomotive fan speed monitoring device provided in this application may further include an extension unit. The angle adjustment-fixing unit is fixed to the support base via the extension unit. The support base may be an adjustable tripod 7, such as... Figure 1 As shown, the opening angle and height of its three outriggers can be independently adjusted, providing stable support on uneven locomotive maintenance pits or complex ground. They can also be electrically extended and rotated in a circular motion. In practical applications, the adjustable tripod 7 is stably erected on the ground at the measurement location, and its height and outrigger angles are adjusted.

[0020] Furthermore, the support base used in this application may also include a connecting rod and a tripod. One end of the connecting rod is fixed to the tripod. The other end of the connecting rod is connected to the extension unit.

[0021] The extension unit can be a lightweight, high-strength carbon fiber tube 1 to reduce the weight of the device. The main function of the carbon fiber tube 1 is to act as a backbone, extending the measuring unit 6 further upwards or laterally from the support base to reach measuring points that are difficult to access directly. Figure 1 As shown, the carbon fiber tube 1 can be connected to the upper end of the support base via the quick-connect kit 3.

[0022] In one exemplary embodiment of this application, in order to select and replace the carbon fiber tube 1 according to the measurement distance requirements, the carbon fiber tube 1 used in this application may include various length specifications, such as: diameter The lengths are 6mm. 1000mm, 7mm 1100mm, 8mm 1200mm, etc.

[0023] In an exemplary embodiment of this application, in order to adjust the angle and position of the measuring unit 6 and accurately deliver the measuring unit 6 fixed on its top to the optimal measuring position and align it with the wind direction, the angle adjustment-fixing unit used in this application may include: a flexible alloy rod 4 and a clamp 8. The flexible alloy rod 4 may be a special alloy rod (such as a carbon steel spring or a nickel-titanium based metal rod) capable of rotating 360 degrees and locking at any bending angle within a flexible metal hose. The flexible alloy rod 4 can be connected to the upper end of the carbon fiber tube 1 via a quick-connect kit 3. For easy disassembly and storage, the quick-connect kit 3 uses a standard-sized quick-release plate and quick-release clamp to achieve quick docking and locking between units. After measurement, the units can be quickly disassembled using the quick-connect kit 3.

[0024] This clamp 8 is mounted on the top of the flexible alloy rod 4 to hold the measuring unit 6. In order to accommodate the installation of different types of anemometers, the clamp 8 used in this embodiment can be a universal mobile phone holder clamp or a universal action camera interface clamp.

[0025] In one exemplary embodiment of this application, to achieve convenient and accurate wind speed monitoring, the measurement unit 6 used is an anemometer. The visual monitoring unit is a camera 2 (such as a miniature high-definition camera that can be rotated and adjusted 360 degrees). Both the anemometer and the camera 2 are fixed on the angle adjustment-fixing unit. The camera 2 is aimed at the anemometer and the heat sink of the composite cooler of the HXD3CA electric locomotive fan. Specifically, by adjusting the posture of the flexible alloy rod 4, the probe of the anemometer is precisely positioned at the wind duct measurement point and aligned with the wind direction, and the wind speed data is remotely read and recorded via the camera 2. The camera 2 can be positioned as follows: Figure 1 The camera is fixed in place using the camera mounting device 4 shown.

[0026] In one exemplary embodiment of this application, to facilitate real-time viewing and archiving by operators, the HXD3CA electric locomotive fan speed monitoring device provided in this application also includes a remote display terminal (such as a mobile phone, tablet, or monitor). The remote display terminal is wirelessly connected to the camera 2. The remote display terminal is used to receive and display the video stream of wind speed data captured by the camera 2 in real time. By adjusting the viewing angle of the camera 2 to directly align with the anemometer and the heat sink of the composite cooler, the video signal is transmitted in real time via wired or wireless means to the mobile phone, tablet, or monitor in the hands of the maintenance personnel, thereby recording the operation process.

[0027] Furthermore, based on the above description, the core of the bendable alloy rod 4 relies on the selection of special materials and the design of an unconstrained connection structure, taking into account bending shape retention, rotational flexibility, and structural stability. The specific material structure settings and matching specifications are as follows: I. Core Materials and Structural Design.

[0028] 1. Special Flexible Alloy Rod Base Material: Utilizing a special flexible metal hose-type alloy rod capable of multi-directional bending, the base material possesses inherent flexibility, allowing for arbitrary adjustment of the bending angle and direction. After bending, it maintains stable shape, ensuring accurate positioning of the anemometer probe. The alloy material also boasts high strength, resisting airflow impact and operational forces, preventing rod deformation and breakage, making it suitable for on-site wind turbine speed measurement.

[0029] 2. Quick-connect kit with unlimited positioning: Both ends of the flexible alloy rod 4 are rigidly connected to the carbon fiber extension rod and the anemometer universal clamp respectively through quick-connect kit 3. The quick-connect structure has no fixed rotation limit, allowing the alloy rod to rotate 360° around the connection point without dead angles. Moreover, the rotation action and the multi-directional bending of the rod itself do not interfere with each other, ensuring full-dimensional adjustment of the measurement posture.

[0030] 3. Lightweight accessory arrangement: The flexible alloy rod 4 only carries the miniature rotating camera 2, without heavy load design, avoiding the extra weight from suppressing the flexibility of the rod and hindering rotation and bending adjustment, ensuring flexibility and adjustment accuracy during manual operation.

[0031] 4. Separation of rigid support and flexible adjustment: The bendable alloy rod 4 serves as an independent flexible adjustment unit. Its bottom is supported by a rigid support system formed by the carbon fiber extension rod and the adjustable tripod 7. The rigid extension rod only serves to extend closer to the measurement point and does not participate in bending and rotation. Structurally, this avoids interference with the adjustment of the alloy rod and ensures its independence in rotation and bending.

[0032] II. Alloy rod compatibility specifications and corresponding measurement parameters.

[0033] The specifications of the flexible alloy rod 4 can be designed according to length gradients to match the conventional usage length of the carbon fiber tube 1. The effective measurement distance is the actual distance from the anemometer probe at the top of the flexible alloy rod 4 to the center of the locomotive cooling fan duct outlet. All specifications support 360° full-range rotation and multi-directional bending at any angle. Specific parameters are shown in Table 1 below.

[0034] Table 1. Alloy Rod Compatibility Specifications and Corresponding Measurement Parameters

[0035] Furthermore, in practical applications, the specifications for the flexible alloy rod 4 adapted to different measurement distances (adapted to common working conditions) can be as follows: (1) Close range (1-3m): Single carbon fiber tube (1.2m) + 0.5m flexible alloy rod.

[0036] (2) Medium distance (3-6m): Two carbon fiber tubes (2.4m spliced) + 0.8m flexible alloy rod.

[0037] (3) Long distance (6-10m): Three carbon fiber tubes (3.6m spliced) + 1.0m flexible alloy rod.

[0038] In one exemplary embodiment of this application, the specific application process of the device provided in this application can be described as follows: First, an adjustable tripod 7 is erected at a suitable location near the HXD3CA electric locomotive (hereinafter referred to as the locomotive) (below the air outlet of the composite cooler fan) as a stable base. The legs and height of the tripod are adjusted according to the ground conditions to ensure its stability. The height is adjusted so that the overall extension angle of the carbon fiber tube 1 and the special alloy rod (i.e., the bendable alloy rod 4) is adapted to the position of the air duct outlet, making it easy to accurately align the anemometer probe with the center of the air duct outlet and with the wind direction.

[0039] The criteria for determining a suitable location may include: 1) The ground is solid and flat, without any hidden dangers such as collapse, slippage, or debris accumulation, which can provide stable support for the tripod.

[0040] 2) The horizontal / vertical distance from the locomotive air duct outlet meets the extension range of the carbon fiber tube + alloy rod, without the need for excessive stretching of the rod.

[0041] 3) The measurement path is not obstructed by equipment, pipelines or other obstacles, and the operator can safely adjust the pole.

[0042] Secondly, the carbon fiber tube 1 is installed on the tripod head as an extension rod using the quick-connect kit 3 (the slot is on the tripod and the buckle is on the carbon fiber tube 1) to get closer to the measurement point.

[0043] Next, a flexible alloy rod 4 is connected to the top of the carbon fiber tube 1 (near the wind turbine speed meter) via a quick-connect kit 3, and a universal clamp is installed at the top of the rod to hold the anemometer. At the same time, a miniature camera that can rotate 360 ​​degrees is installed on the flexible alloy rod 4 and adjusted to be aligned with the anemometer's display screen.

[0044] Then, by manually adjusting the bending angle and direction of the flexible alloy rod 4, the anemometer probe is precisely positioned at the center of the duct outlet and aligned with the wind direction.

[0045] Finally, the operator views the real-time footage transmitted from camera 2 through a remote display terminal, reads and records the wind speed data, and quickly disassembles and stores each unit after the measurement is completed.

[0046] Based on the above description, compared with the prior art, this application has at least the following advantages: 1. Improved measurement adaptability: This application, through unit combination and multi-level adjustment, can adapt to various complex spatial structures such as the bottom of locomotives, and achieve precise positioning.

[0047] 2. Ensure data accuracy: This application adopts a stable support and adjustable angle to ensure that the probe is aligned with the wind direction, and remote visual readings avoid human error.

[0048] 3. Enhanced operational safety: Operators can complete all operations from the ground without having to enter narrow or dangerous locations.

[0049] 4. Convenient and efficient operation: The quick-connect kit is designed for rapid assembly and disassembly, making it easy to carry and reuse.

[0050] 5. Facilitates preventative maintenance: Convenient and regular monitoring allows for timely detection of fan malfunctions and prevention of failures.

[0051] In summary, addressing the challenges of traditional wind speed measurement caused by the concealed location and confined space of the HXD3CA electric locomotive's composite cooler duct, this application achieves convenient and accurate wind speed monitoring through a modular device and remote vision-assisted operation. Specifically, an adjustable (extendable and rotatable) tripod is used to establish a stable measurement base in complex ground environments. A carbon fiber extension rod extends the measurement unit to the target area. A special alloy rod with a 360-degree adjustable, bendable, and lockable flexible metal hose is used to adjust the angle and position of the measurement unit, aligning it with the duct outlet. A 360-degree rotating camera remotely acquires real-time anemometer readings. The support base, extension unit, and angle adjustment / fixing unit are quickly assembled and disassembled using quick-connect kits, offering flexible operation and strong adaptability. This effectively improves the accuracy and safety of wind speed monitoring in confined spaces, facilitates routine preventative maintenance, and ensures safe locomotive operation.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
