Description

Technical Field

[0001] This utility model relates to the technical field of outdoor light sources, and in particular to a light source detection device for outdoor testing. Background Technology

[0002] Outdoor light source detection devices refer to light source modules plus camera detection modules, which enable the detection of outdoor scenes.

[0003] Light source detection in outdoor scenarios requires high-brightness light sources with large illumination areas, while also being able to withstand extreme weather conditions such as sun exposure and rain.

[0004] The following example of a specific outdoor application scenario illustrates the drawbacks of outdoor light source detection devices.

[0005] In outdoor applications, such as railway track infrastructure, the demand for intelligent inspection of track infrastructure is becoming increasingly urgent as railway transportation develops towards higher speeds, heavier loads, and higher density. Machine vision-based inspection systems (such as rail surface damage detection, sleeper condition recognition, and fastener missing inspection) have become core technologies for modern railway operation and maintenance. However, existing outdoor lighting inspection devices for railways have the following shortcomings in practical applications:

[0006] 1. Low integration and complicated assembly and debugging: The light source module and camera detection module of the outdoor light source detection device are usually purchased in batches and then assembled and debugged on site. This discrete combination design has low integration and complicated assembly and debugging.

[0007] 2. Insufficient lighting area and brightness: Outdoor light source detection devices are usually installed under the train or next to the track, and their installation space is limited. Therefore, existing outdoor light source devices usually use LED light strips for illumination, which leads to: (1) Narrow illumination area, making it difficult to cover the complete area of ​​the rail head, rail web, rail bottom, and even part of the track bed; (2) Low illumination brightness, as the brightness of the parallel light emitted by the LED light strips is low, resulting in unclear illumination imaging in dark scenes such as night or tunnels.

[0008] 3. Poor protection of the camera detection module, which can easily lead to camera lens contamination: Outdoors, it is easy for wind and rain to occur, or for dust to be generated by the friction between train wheels and rails. Dust and rain splashes can easily cause camera lens contamination, resulting in a decrease in camera detection performance. Utility Model Content

[0009] The purpose of this invention is to overcome the aforementioned defects in the prior art and provide a light source detection device for outdoor testing. This light source detection device integrates the camera component and the light source component inside the housing, achieving a high degree of integration. Users can use it directly after purchase, and assembly and debugging are simple. In addition, several surrounding light source components are arranged at a certain angle, which not only forms a large illumination area, but also creates a large illumination brightness due to the overlapping illumination between several light source components. Furthermore, the camera is protected by the camera window glass, and the light source components are protected by the light source window glass, thereby ensuring that the camera and light source components are not contaminated.

[0010] To achieve the above objectives, this utility model provides a light source detection device for outdoor testing, comprising a housing, an installation base inside the housing, a through hole in the center of the installation base, a camera assembly mounted on the installation base, the camera assembly including a camera extending out of the through hole, a plurality of inclined mounting surfaces at a certain angle surrounding the through hole of the installation base, a light source assembly mounted on the inclined mounting surfaces, a housing cover mounted on the top of the installation base, the housing cover covering the housing, a camera window glass corresponding to the camera in the center of the housing cover, and a plurality of inclined light source window glasses corresponding to the light source assemblies surrounding the camera window glass of the housing cover.

[0011] Preferably, the bottom of the housing is equipped with a mounting plate.

[0012] Preferably, a waterproof and breathable valve is installed on one side of the housing.

[0013] Preferably, one side of the housing is externally connected to a camera power cable electrically connected to the camera assembly and a light source power cable electrically connected to the light source assembly.

[0014] Preferably, the housing has a heat dissipation cavity inside, the top of the heat dissipation cavity is provided with a first annular support seat, and the bottom of the housing cover is provided with a second annular support seat. The first annular support seat and the second annular support seat are fixed together by bolts.

[0015] Preferably, the inner side of the first annular receiving seat is provided with an annular locking block, and the bottom of the mounting body is provided with an annular locking groove or an annular opening, and the annular locking block is inserted into the annular locking groove or annular opening.

[0016] Preferably, a waterproof sealing ring is installed between the first annular bearing seat and the second annular bearing seat.

[0017] Preferably, the camera assembly further includes a camera circuit board mounted on the bottom of the mounting base, and the camera is mounted on the camera circuit board.

[0018] Preferably, the light source assembly includes a light source circuit board and a plurality of LED light sources mounted on the light source circuit board.

The mounting base of this utility model is installed between the housing and the cover, and integrates the camera component and the light source component inside the housing and the cover respectively. It has the advantages of high integration, ready to use after purchase, and simple assembly and debugging.

[0022] 2. In this utility model, several light source components are inclined at a certain angle around the through hole of the mounting base. Firstly, the light source circuit board of the light source components inclined at a certain angle can carry more LED light sources (compared to parallel LED light strips), thereby making the illumination brightness higher. Secondly, the light source components inclined at a certain angle can form a larger illumination area. Thirdly, the light from the light source components inclined at a certain angle overlaps with each other, further improving the illumination brightness.

Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 6This utility model provides a light source detection device for outdoor testing, including a housing 2. A mounting base 3 is installed inside the housing 2. A through hole 31 is opened in the middle of the mounting base 3. A camera assembly 4 is installed on the mounting base 3. The camera assembly 4 includes a camera 41, which extends out of the through hole 31. A plurality of mounting inclined surfaces 32 are provided around the through hole 31 of the mounting base 3 at a certain angle. A light source assembly 5 is installed on the mounting inclined surfaces 32. A cover 30 is installed on the top of the mounting base 3. The cover 30 covers the housing 2. A camera window glass 6 corresponding to the camera 41 is provided in the middle of the cover 30. A plurality of light source window glass 7 corresponding to the light source assembly 5 are provided around the camera window glass 6 of the cover 30 at a certain angle.

[0036] The bottom of the housing 2 is equipped with a mounting plate 1, which facilitates the user to install the light source detection device for outdoor testing according to an embodiment of the present invention outdoors.

[0037] A waterproof and breathable valve 8 is installed on one side of the housing 2. The waterproof and breathable valve 8 prevents water vapor from entering the housing 2 and can discharge water vapor in time, thereby avoiding fogging of the camera 41 of the camera assembly 4 and the light source assembly 5, and avoiding a decrease in the light source detection quality.

[0038] One side of the housing 2 is externally connected to a camera power cable 45, which is electrically connected to the camera assembly 4, and a light source power cable 55, which is electrically connected to the light source assembly 5. The camera power cable 45 is electrically connected to the camera circuit board 40 mentioned below, and the light source power cable 55 is electrically connected to the light source circuit board 50 mentioned below.

[0039] The housing 2 has a heat dissipation cavity 20 inside, the top of the heat dissipation cavity 20 is provided with a first annular support 28, and the bottom of the housing cover 30 is provided with a second annular support 48. The first annular support 28 and the second annular support 48 are fixed together by bolts.

[0040] The inner side of the first annular receiving seat 28 is provided with an annular locking block 29, and the bottom of the mounting body 3 is provided with an annular groove or annular opening 39, with the annular locking block 29 inserted into the annular groove or annular opening 39. The annular groove or annular opening 39 and the annular locking block 29 ensure that the mounting body 3 is stably installed on the housing 2.

[0041] A waterproof sealing ring 91 is installed between the first annular bearing seat 28 and the second annular bearing seat 48. The waterproof sealing ring 91 ensures the waterproof protection performance between the housing 2 and the cover 30.

[0042] The camera assembly 4 also includes a camera circuit board 40 mounted on the bottom of the mounting base 3, and the camera 41 is mounted on the camera circuit board 40.

The light-emitting lens converts the point light source emitted by the LED beads into a surface light source with a certain light-emitting angle (such as 30 degrees, 45 degrees, 60 degrees, etc.).

[0044] Silicone pads 92 are provided on both the upper and lower sides of the camera window glass 6 and several light source window glass 7. The silicone pads 92 serve two purposes: firstly, to provide shock absorption for the camera window glass 6 and the light source window glass 7 (to prevent vibration caused by friction from outdoor trains), and secondly, to provide waterproof protection.

[0045] The working principle of a light source detection device for outdoor testing according to an embodiment of this utility model is as follows: Figure 6 As shown, light emitted from several light source components 5, which are tilted at a certain angle, passes through the light source window glass 7, forming a pattern as shown in the image. Figure 6 The camera 41, located in the center of the illumination field, takes pictures of the outdoor scene on the illumination field, such as the surface of the rails, the condition of the sleepers, or other railway facilities.

[0046] The technical advantages of a light source detection device for outdoor testing according to an embodiment of this utility model are as follows:

[0047] 1. This light source detection device for outdoor testing integrates camera component 4 and light source component 5 together, which has the advantages of high integration, ready to use after purchase, and simple assembly and debugging;

[0048] 2. Several light source components 5 are installed on the mounting slope 32 around the through hole 31 of the mounting base 3 and are set at a certain angle, so that the light source components 5 are also set at a certain angle. The light of the light source components 5 set at a certain angle overlaps with each other, further improving the lighting brightness. In addition, the light source components 5 set at a certain angle can form a larger lighting area.

[0049] 3. The camera 41 is protected by the camera window glass 6, and the light source assembly 5 is protected by the light source window glass 7, to prevent the lens of the camera 41 and the light source assembly 5 from being contaminated. At the same time, the silicone pad 92 and the waterproof sealing ring 91 ensure that the space between the housing 2 and the cover 30, the mounting point of the camera window glass 6 and the mounting point of the light source window glass 7 are waterproof. In addition, the heat dissipation cavity 20 ensures effective heat dissipation of the light source assembly 5, and the waterproof vent valve 8 prevents the lens of the camera 41 and the light source assembly 5 inside the space between the housing 2 and the cover 30 from fogging.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
