Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle safety inspection equipment, specifically a miniaturized, low-maintenance railway freight car operation fault image detection device. Background Technology
[0002] The Freight Car Fault Trackside Image Detection System (TFDS) is an important component of the "5T" safety prevention and early warning system, and a crucial technological guarantee for upgrading my country's traditional manual inspection operation mode to machine inspection. Therefore, it is necessary to ensure that the trackside TFDS equipment can be used normally in any environment to ensure train operation safety.
[0003] However, since the TFDS equipment is located outdoors, raindrops and oil stains often accumulate on the lens surface during the rainy season and cannot be slid off. The dirt and dust accumulation on the lens in the bottom box of the TFDS equipment, especially when shooting the bottom of the vehicle (coupler buffer, bogie, and middle part) in rainy weather, has always been a difficult problem to solve. Even if the existing equipment is equipped with a blower dust removal device, it is difficult to remove oil stains, mud and water and other adhering substances. Therefore, the dirt on the lens and rainwater conditions prevent the operation department from passing the TFDS vehicle inspection normally.
[0004] To ensure the TFDS team in the operations department can perform normal vehicle inspections and reduce manual inspections, the dynamics workshop arranges for maintenance personnel to clean the mirrors on-site. However, due to rain, the image quality can only be maintained for a short time after cleaning. The dynamics department faces numerous hidden dangers in terms of personnel organization, operations, and traffic safety, and cannot fundamentally solve the problem of blurry photos.
[0005] With the cancellation of off-site operations in the vehicle department, the number of times vehicles need to be inspected manually will increase significantly if the lens is dirty or the equipment is "paralyzed" in rainy weather, which will seriously affect the production organization and production order of the workshop. In order to completely solve this problem, this patent has developed a miniaturized, low-maintenance railway freight car operation fault image detection device to solve the above problems. Utility Model Content
[0006] Therefore, the technical problem to be solved by this utility model is to provide a miniaturized, low-maintenance railway freight car operation fault image detection device, which effectively solves the existing problems that often occur during the rainy season when raindrops and oil stains accumulate on the lens surface and cannot be slid off, and the lens of the TFDS equipment bottom box is dirty and dusty, especially when taking pictures of the bottom of the vehicle (coupler buffer, bogie, and middle part) in rainy weather. This has always been a difficult problem to solve. Even if the existing equipment is equipped with a blower dust removal device, it is difficult to remove oil stains, mud and other adhering substances. Therefore, the lens dirt and rainwater conditions cause the operating department to be unable to carry out TFDS inspection operations normally.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] A miniaturized, low-maintenance railway freight car operation fault image detection device includes a main unit, which is equipped with a camera lens and a laser lens. A power supply connector and a signal connector are fixedly connected to one side of the main unit. A protective lens is fixedly installed on one side of the main unit to protect the camera lens and the laser lens. An automatic cleaning device for cleaning the protective lens is installed on the main unit.
[0009] The automatic cleaning device includes a cleaning scraper rotatably connected to one side of the main unit, a drive device for driving the cleaning scraper to swing is fixedly connected to one side of the main unit, and a wiper is installed on the side of the cleaning scraper near the protective lens.
[0010] Preferably, a nozzle is installed on one side of the main unit, and the nozzle is connected to the water storage tank through a pipe.
[0011] Preferably, an indicator light is installed on one side of the host.
[0012] Preferably, there are three indicator lights, and the three indicator lights are all different colors.
[0013] Preferably, handles are rotatably connected to both sides of the main unit, and torsion springs are provided between the handles and the main unit.
[0014] Preferably, the host has multiple spaced heat dissipation grooves on one side.
[0015] Preferably, the host has multiple mounting holes on the side opposite to the heat dissipation groove.
[0016] Preferably, the host is equipped with a waterproof and breathable valve.
[0017] The technical solution of this utility model has achieved the following beneficial technical effects:
[0018] Compared with existing image acquisition devices, this application adds an automatic cleaning device. The original image acquisition device only has a blower dust removal function. However, in the outdoor environment of railway lines, there will be sticky objects such as oil stains during long-term operation, which are difficult to clean the surface of the device. Therefore, this application adds an automatic cleaning device to clean the surface of the image acquisition device, thereby reducing the frequency of online maintenance. Attached Figure Description

[0025] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.
[0026] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0027] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.
[0028] Example 1: A miniaturized, low-maintenance railway freight car operation fault image detection device includes a main unit 1. The main unit 1 is equipped with a camera lens and a laser lens. The working principle is based on the advantages of high brightness and good directionality of laser, combined with a high-speed linear scan camera. Through the relative movement of the object and the device, image acquisition of surface information of the object being measured is achieved. The camera lens is used to capture images. A power supply connector 2 and a signal connector 3 are fixedly connected to one side of the main unit 1. The power supply connector 2 is used to provide power to the main unit 1, and the signal connector 3 is used to transmit signals. In use, the power supply connector 2 and the signal connector 3 are plugged into the car body. A protective lens 4 is fixedly installed on one side of the main unit 1. The protective lens 4 is used to protect the camera lens and the laser lens. The camera lens and the laser lens are installed inside the main unit 1. In use, the camera lens and the laser lens pass through the protective lens 4 to acquire image information. An automatic cleaning device for cleaning the protective lens 4 is installed on the main unit 1.
[0029] The automatic cleaning device includes a cleaning scraper 5 rotatably connected to one side of the main unit 1. A drive device for driving the cleaning scraper 5 to swing is fixedly connected to one side of the main unit 1. The drive device is used to control the swing of the cleaning scraper 5. The drive device uses a servo motor or a stepper motor to control the swing of the cleaning scraper 5. A wiper 6 is installed on the side of the cleaning scraper 5 near the protective lens 4. In use, the drive device controls the swing of the cleaning scraper 5 so that the wiper 6 swings synchronously to clean the protective lens 4.
[0030] A mounting plate is slidably connected to the cleaning scraper 5 near the protective lens 4. The mounting plate has a T-shaped locking groove inside. A T-shaped locking block that mates with the locking groove is fixedly connected to one end of the wiper 6 near the cleaning scraper 5. In use, the T-shaped locking block is slidably engaged with the locking groove to mount the wiper 6 onto the cleaning scraper 5, facilitating wiper 6 replacement. The cleaning scraper 5 has multiple evenly spaced limiting holes. A limiting shaft that slidably connects to the limiting holes is fixedly connected to one side of the mounting plate near the limiting holes. A compression spring is installed between the cleaning scraper 5 and the mounting plate. Initially, the compression spring pushes the mounting plate towards the protective lens 4, thereby pushing the wiper 6 towards the protective lens 4, ensuring a tight fit between the wiper 6 and the protective lens 4, thus improving the cleaning effect.
[0031] A nozzle 7 is installed on one side of the main unit 1. The nozzle 7 is connected to a water tank through a pipe. When in use, the water tank is filled with cleaning fluid. The water tank is equipped with a water pump. When it is necessary to clean the protective lens 4, the water pump is started to draw out the cleaning fluid from the water tank and spray it onto the protective lens 4 through the nozzle 7. The drive device is started to drive the cleaning scraper 5 to swing, and the wiper 6 cleans the protective lens 4, thereby cleaning the oil stains and other substances on the protective lens 4.
[0032] An indicator light 9 is installed on one side of the host 1; there are three indicator lights 9. When the three indicator lights 9 are lit, they respectively indicate that the camera is powered on, the laser is powered on, and the laser is emitting light. The three indicator lights 9 are all different colors, so as to facilitate the observation of whether the device is powered on.
[0033] Both sides of the main unit 1 are rotatably connected to handles 10. A torsion spring is provided between the handles 10 and the main unit 1. In the initial state, the torsion spring drives the handles 10 to swing towards the main unit 1, thereby controlling the handles 10 to fit against both sides of the main unit 1. In use, the handles 10 are rotated away from the main unit 1, so that the handles 10 will not shake randomly and thus affect the main unit 1.
[0034] The host 1 has multiple spaced heat dissipation grooves 11 on one side, thereby increasing the contact area with air and improving the heat dissipation effect.
[0035] The host 1 has multiple mounting holes 12 on the side away from the heat dissipation groove 11. In use, the host 1 is placed in the position to be installed, and the host 1 is fixed in a fixed position by fixing the bolts into the mounting holes 12 to prevent the host 1 from sliding.
[0036] The main unit 1 is equipped with a waterproof and breathable valve 13, which is used to balance the air pressure inside and outside the main unit 1 and to provide waterproof protection for the main unit 1.
[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
