Description

Technical Field

[0001] This application relates to the technical field of field equipment protection, and in particular to a field infrared camera protection structure. Background Technology

[0002] In the field of wildlife conservation, infrared cameras are one of the important tools for ecological monitoring. However, when infrared cameras are deployed in the wild, they are easily affected by the external environment, such as dust, humidity, and collisions.

[0003] Therefore, a protective casing is installed around the infrared camera, with only the camera and sensors exposed, while the rest of the camera is protected. The lens is exposed for extended periods, inevitably accumulating dust and water stains, which cannot be cleaned promptly due to its location in the wild. Utility Model Content

[0004] To address the aforementioned technical issues, this application provides a protective structure for an outdoor infrared camera.

[0005] This application provides a protective structure for an outdoor infrared camera, employing the following technical solution: A protective structure for an outdoor infrared camera, comprising: The first main housing has a first through slot; The second main housing is detachably connected to the first main housing. There is space between the first main housing and the second main housing for the installation of an infrared camera. The lens of the infrared camera faces the first through slot. A protective film is installed inside the first main housing, and the protective film covers the first through groove; An automatic film-changing mechanism is installed inside the first main housing and is used to switch the protective film.

[0006] By adopting the above technical solutions, in the field environment, pollutants such as dust and rainwater adhere to the surface of the protective film rather than the lens, avoiding lens wear or optical performance degradation; when the protective film is contaminated to the point of affecting imaging, the automatic film replacement mechanism is activated to switch to a new protective film, without the need for personnel to arrive on site, achieving physical isolation between the lens and the harsh environment, and extending the camera's service life; through automated operation, the shortcomings of field maintenance are avoided, ensuring long-term stable imaging of the infrared camera.

[0007] Optionally, the automatic film changing mechanism includes a feeding shaft, a receiving shaft, and a driving component for rotating the receiving shaft and the receiving shaft. The feeding shaft and the receiving shaft are rotatably mounted on the first main housing. One end of the protective film is fixedly mounted on the feeding shaft, and the other end of the protective film is fixedly mounted on the receiving shaft.

[0008] By adopting the above technical solution, when the protective film is contaminated, the drive unit drives the take-up shaft to rotate, and the feed shaft releases new film accordingly. The take-up shaft wraps and recycles the waste protective film, and at the same time, the feed shaft releases unused new protective film until the new film completely covers the first through groove and then the drive unit stops.

[0009] Optionally, a positioning frame is installed on the first main housing, the positioning frame is located between the feeding shaft and the receiving shaft, the positioning frame is connected to the first through groove, and the protective film passes through the positioning frame.

[0010] By adopting the above technical solution, when the receiving shaft rotates and drives the protective film to move, the channel of the positioning frame always guides the protective film, further reducing the occurrence of left-right displacement or up-down wrinkles in the protective film.

[0011] Optionally, the positioning frame is formed by splicing two sub-frames in half, and the protective film is held between the two sub-frames.

[0012] By adopting the above technical solution, the two sub-frames are separated, the protective film is laid flat on the clamping surface of one of the sub-frames, and then the other sub-frame is aligned and spliced, so that the protective film is tightly clamped between the two sub-frames to form a complete positioning frame structure.

[0013] Optionally, a cleaning strip is installed on the sub-frame, and the cleaning strip is in contact with the protective film.

[0014] By adopting the above technical solution, when the receiving shaft drives the protective film to move, the surface of the protective film rubs against the cleaning strip, and automatic cleaning is achieved by relying on the film replacement action. The structure is simple and suitable for the field environment.

[0015] Optionally, the first main housing is detachably connected to a mounting base, the positioning frame is inserted into the mounting base, the mounting base is provided with a fixing member for fixing the positioning frame, and the automatic film changing mechanism is mounted on the mounting base.

[0016] By adopting the above technical solution, when it is necessary to replace the protective film roll or repair the drive component, simply loosen the connection structure between the mounting base and the main housing, detach the mounting base from the main housing as a whole, and then maintain the components thereon; after maintenance, simply reinstall the mounting base back into the main housing without moving the infrared camera.

[0017] Optionally, the mounting base has a first mounting cavity and two second mounting cavities. The positioning frame is installed in the first mounting cavity. The first through groove communicates with the first mounting cavity. The two second mounting cavities communicate with the first mounting cavity respectively. The feeding shaft and the receiving shaft are located in the second mounting cavities respectively.

[0018] By adopting the above technical solution, when the drive component drives the receiving shaft to rotate, the feeding shaft releases the protective film in its own cavity. The protective film moves along the fixed path of the second mounting cavity, the first mounting cavity, and the second mounting cavity. The side walls of each cavity limit the component and prevent the shaft from shaking or the film from shifting.

[0019] Optionally, the fastener is installed in the second mounting cavity. The fastener includes a fixing block and a bolt. A positioning block is fixedly connected to the inner wall of the second mounting cavity. The fixing block abuts against the positioning block. The bolt passes through the fixing block and is threadedly connected to the positioning block.

[0020] By adopting the above technical solution, the bolt connection structure is simple and reliable, and facilitates field maintenance operations.

[0021] In summary, this application includes at least one of the following beneficial effects: 1. The protective film replaces the lens for direct exposure, isolating dust, moisture, and minor impacts at the source; the automatic film changing mechanism solves the problem of cleaning the protective film after it becomes contaminated. 2. When releasing new membranes and recycling old membranes, the old membranes are automatically cleaned by the membrane replacement process, which improves the utilization rate of the protective membranes and extends their service life.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5This application will be described in further detail.

[0025] This application discloses a protective structure for an outdoor infrared camera.

[0026] Reference Figure 1 A protective structure for an outdoor infrared camera includes a first main housing 10 and a second main housing 20, which are assembled by a detachable connection using bolts 82. After assembly, an installation space adapted to the shape of the infrared camera is formed inside, facilitating the insertion and removal of the infrared camera. The front of the first main housing 10 has a circular or square first through slot 11. When the infrared camera is installed in the space between the two main housings, it must be ensured that the camera lens is precisely facing the first through slot 11 so that the field of view of the lens can extend to the outside through the first through slot 11.

[0027] Reference Figure 2 To avoid direct exposure of the lens, a transparent protective film 30 is detachably installed on the outside of the first main housing 10. The size of the protective film 30 is larger than the first through groove 11, and it can completely cover the area of ​​the first through groove 11, isolating pollutants such as dust, rainwater and mosquitoes in the wild from the source, while not affecting the penetration and imaging effect of infrared light.

[0028] Reference Figure 2 A positioning frame 50 and a mounting base 60 are also installed outside the first main housing 10, and a protective film 30 is installed between the mounting base 60 and the positioning frame 50. The mounting base 60 is fixedly installed on the first main housing 10 by an elastic rope or a clamp, and the first main housing 10 has a groove 12 for the mounting base 60 and the positioning frame 50 to be inserted.

[0029] Reference Figure 3 and Figure 4 The first main housing 10 also integrates an automatic film changing mechanism 40. This mechanism works in conjunction with the protective film 30 to automatically replace the protective film 30 without requiring on-site personnel operation. The automatic film changing mechanism 40 comprises a feeding shaft 41, a receiving shaft 42, and a drive component 43. One end of the protective film 30 is fixedly connected to the feeding shaft 41, and the other end is fixedly connected to the receiving shaft 42. The feeding shaft 41, receiving shaft 42, and drive component 43 of the automatic film changing mechanism 40 are all integrated and mounted on the mounting base 60. There are two drive components 43, specifically small motors, mounted on the mounting base 60 and connected to the feeding shaft 41 and receiving shaft 42 respectively, driving them to rotate synchronously. When the feeding shaft 41 rotates to release the film, the receiving shaft 42 rotates to collect the film.

[0030] Reference Figure 3The mounting base 60 features a chambered design, with a first mounting cavity 61 and two symmetrically distributed second mounting cavities 62. The first mounting cavity 61 is located in the center of the mounting base 60, corresponding to the first through slot 11 of the first main housing 10. The positioning frame 50 is inserted and fixed within the first mounting cavity 61, and both ends of the first mounting cavity 61 are connected to the two second mounting cavities 62. The feeding shaft 41 and the receiving shaft 42 are rotatably mounted within the two second mounting cavities 62, respectively. This chambered layout provides spatial isolation between the components, while the side walls of the chambers protect the internal components.

[0031] The inner channel of the positioning frame 50 is connected to the first through slot 11. After the protective film 30 is released from the feeding shaft 41, it will first pass through the inner channel of the positioning frame 50 and then connect to the receiving shaft 42. The inner wall of the channel of the positioning frame 50 is closely fitted with the edge of the protective film 30, forming a rigid constraint on the movement trajectory of the protective film 30, ensuring that the protective film 30 remains flat and aligned with the lens during the film replacement process, effectively reducing the imaging occlusion problem caused by wrinkles or offset.

[0032] Reference Figure 3 A fixing component 80 is installed on the mounting base 60 to fix the positioning frame 50. The fixing component 80 includes a fixing block 81 and a bolt 82. A positioning block 63 is pre-welded to the inner wall of the second mounting cavity 62. The positioning block 63 has an internal threaded hole. After the feeding shaft 41 or the receiving shaft 42 is installed in place, the fixing block 81 is abutted against the end of the shaft and fits against the positioning block 63. Then, the bolt 82 is passed through the through hole on the fixing block 81 and tightened into the internal threaded hole of the positioning block 63. The pre-tightening force of the bolt 82 causes the fixing block 81 to abut against the positioning frame 50 and the positioning block 63, fixing the positioning frame 50 on the mounting base 60. The feeding shaft and the unloading shaft 41 are respectively inserted into the fixing block 81 and are in rotatable contact with the fixing block 81.

[0033] Reference Figure 5 The positioning frame 50 is made up of two identical sub-frames spliced ​​together. The mating surfaces of the two sub-frames are respectively provided with matching slots 51 and protrusions 52. The protective film 30 is clamped between the mating surfaces of the two sub-frames. This splicing structure greatly simplifies the installation and replacement of the protective film 30. There is no need to thread the protective film 30 through one end of the positioning frame 50. The protective film 30 can be placed or removed directly by simply separating the two sub-frames.

[0034] Reference Figure 5 Flexible cleaning strips 70 are also embedded on the mating surfaces of the two sub-frames. The cleaning strips 70 are made of high-density brushes or chamois material. Their surfaces are in close contact with the upper and lower surfaces of the protective film 30 without causing damage. When the protective film 30 moves with the film replacement action, the cleaning strips 70 can simultaneously brush away the floating dust and light stains attached to the film surface, realizing the integrated function of film replacement and cleaning, and further improving the cleanliness of the protective film 30 entering the work area.

[0035] The implementation principle of a field infrared camera protection structure according to an embodiment of this application is as follows: First, install the drive unit 43, feed shaft 41, and take-up shaft 42 into the second chamber of the mounting base 60. Install the protective film 30 on the positioning frame 50, allowing it to move within the frame. Then, roll the protective film 30 onto the unloading shaft. When installing the positioning frame 50 onto the mounting base 60, the protective film 30 remains taut. Next, fix the entire mounting base 60 to the outside of the first main housing 10 using bolts 82, ensuring the positioning frame 50 is aligned with the first through-slot 11. Place the infrared camera into the space between the two housings and align the lens with the first through-slot 11. Assemble the first main housing 10 and the second main housing 20. In field use, the protective film 30 prevents contaminants from directly contacting the lens. The cleaning strip 70 cleans both the old and new films simultaneously during film replacement. When the protective film 30 becomes contaminated, the automatic film replacement mechanism 40 completes the replacement. Maintenance of the automatic film replacement mechanism 40 can be achieved simply by removing the mounting base 60.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
