Description

Technical Field

[0001] This utility model relates to the field of blackbody calibration, and in particular to a general-purpose blackbody calibration platform for photoelectric measurement equipment. Background Technology

[0002] Blackbody calibration is a crucial step in the calibration process of infrared thermal imagers. A blackbody is an object that completely absorbs all radiant energy, with an emissivity close to or equal to 1. In infrared thermal imaging, a blackbody is used as a reference point, equivalent to a zero point. Blackbody calibration involves comparing the difference between the blackbody temperature measured by the infrared thermal imager and the actual blackbody temperature. This allows for the adjustment of the imager's parameters, improving measurement accuracy. Through blackbody calibration, the parameters of the infrared thermal imager can be adjusted, reducing measurement errors and improving accuracy. Under different measurement environments and conditions, blackbody calibration ensures the consistency of temperature measurements by the infrared thermal imager. The principle of blackbody calibration is based on the blackbody radiation law, namely, the radiant power of a blackbody is proportional to the fourth power of its temperature (Stefant-Boltzmann law). By measuring the radiant power of a blackbody at different temperatures, the response curve of the photoelectric measurement equipment can be established, thereby calibrating the equipment. Blackbody calibration has wide applications in vehicle inspection, industrial inspection, environmental monitoring, and other fields.

[0003] In optoelectronic measurement equipment, blackbody calibration is a crucial process that ensures the accuracy and reliability of measurement results. The authorized Chinese utility model patent "Announcement No.: CN204871061U, Title: Blackbody Radiation Source for Rapid Calibration" utilizes multiple blackbodies as heat sources, allowing for multiple temperature settings and improving the efficiency of on-site personnel to achieve rapid temperature calibration. The blackbody used has a uniform rough surface, high thermal conductivity, and a large heat dissipation surface area. Simultaneously, its uniform and fine surface ensures even temperature distribution, effectively improving calibration results when calibrating infrared thermometers. However, the aforementioned application requires multiple blackbodies, and the distance between the blackbodies and the infrared thermometer is fixed. The calibration distance varies depending on the surrounding environment, which can affect the accuracy of the calibration and makes it difficult to adapt to different models of optoelectronic measurement equipment.

[0051] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0052] Figures 1 to 3 The diagram shown is a structural schematic of an embodiment of the universal blackbody calibration platform for photoelectric measurement equipment of this utility model. The universal blackbody calibration platform for photoelectric measurement equipment includes a support platform 1.

[0056] The movable component 6 is used to move the lifting component 5 and adjust the distance between the lifting component 5 and the mounting platform 3.

[0057] In this technical solution, the height of the artificial blackbody 4 can be adjusted by the lifting component 5, so that a single artificial blackbody 4 can be used to calibrate photoelectric measuring equipment of different sizes. The distance between the mounting platform 3 and the placement frame 2 can be adjusted by the moving component 6, which in turn adjusts the distance between the artificial blackbody 4 and the photoelectric measuring equipment. This allows the calibration distance to be adjusted according to different surrounding environments and different models of photoelectric measuring equipment. It is highly flexible in use and can adapt to the blackbody calibration of photoelectric measuring equipment of different models and in different environments, with high versatility.

[0058] The lifting assembly 5 includes a mounting housing 51, and two symmetrically distributed threaded shafts 52 are provided in the inner cavity of the mounting housing 51.

[0059] Both threaded shafts 52 are threadedly connected to movable plates 53, and a rotating bar 54 is provided above the movable plates 53.

[0060] Both ends of the rotating column 54 are rotatably connected to rotating frames 55. The lower rotating frame 55 is connected to the top of the movable plate 53, and the lower rotating frame 55 is connected to the mounting platform 3.

[0061] In this technical solution, the height of the artificial blackbody 4 can be adjusted using the lifting component 5.

[0062] The mounting housing 51 has a preset hole on its side, and one end of the threaded shaft 52 is rotatably connected to the side of the mounting housing 51 through the preset hole.

[0063] The two threaded shafts 52 are connected at their adjacent ends to the output end of the bidirectional power source 56, which is installed in the inner cavity of the mounting housing 51.

[0064] In this technical solution, the bidirectional power source 56 can provide driving force for the rotation of the threaded shaft 52.

[0065] The inner wall of the mounting housing 51 is connected to a plurality of fixed rails 57, and the surface of the fixed rails 57 is slidably connected to the movable plate 53.

[0066] In this technical solution, the movement trajectory of the moving plate 53 can be limited by using the fixed track 57.

[0067] In use, the bidirectional power source 56 drives the two threaded shafts 52 to rotate, thereby driving the two movable plates 53 to move along the fixed track 57 respectively, so that the two movable plates 53 can move towards each other or away from each other. At this time, under the action of the rotating frame 55, the rotating column 54 can rotate, thereby driving the mounting platform 3 to move up and down, and then driving the artificial blackbody 4 to move in the same direction, thus adjusting the height of the artificial blackbody 4.

[0068] The moving component 6 includes a bidirectional drive source 61, which is connected to the bottom of the mounting housing 51;

[0069] Both output ends of the bidirectional drive source 61 are connected to a drive shaft 62. The end of the drive shaft 62 away from the bidirectional drive source 61 is connected to a rotating gear 63. The bottom side of the rotating gear 63 is meshed with a fixed rack 64, and the fixed rack 64 is connected to the top of the support platform 1.

[0070] In this technical solution, the lateral distance of the artificial blackbody 4 can be controlled by the moving component 6.

[0071] The bottom of the mounting housing 51 is connected to two symmetrically distributed support side plates 65, and the surface of the drive shaft 62 is rotatably connected to the support side plates 65.

[0072] In this technical solution, the support side plate 65 can support the transmission shaft 62, and at the same time, the mounting housing 51 and other structures can move with the movement of the rotating gear 63.

[0073] The bottom of the support side plate 65 is connected to an anti-detachment slider 66, and the top surface of the support platform 1 has two symmetrically distributed track grooves. The anti-detachment slider 66 is slidably connected to the top side of the support platform 1 through the sliding groove.

[0074] In this technical solution, the movement trajectory of the support side plate 65 can be limited by using the anti-detachment slider 66.

[0075] In use, the bidirectional drive source 61 drives the transmission shaft 62 to rotate, which in turn drives the rotating gear 63 to rotate. At this time, under the action of the fixed rack 64, the rotating gear 63 can move, which can drive the anti-detachment slider 66 and the lifting component 5 to move in the same direction, and then drive the mounting platform 3 and the artificial blackbody 4 to move in the same direction, so that the distance between the artificial blackbody 4 and the placement platform 2 can be adjusted.

[0076] A synchronous locking component 7 is provided between the lifting component 5 and the moving component 6. The synchronous locking component 7 includes a follower gear 71 and a locking bar 72.

[0077] The follower gear 71 is connected to one end of the threaded shaft 52, and a locking strip 72 is provided between the follower gear 71 and the rotating gear 63;

[0078] A plurality of sliding posts 73 are connected to one side of the locking strip 72, and the sliding posts 73 are slidably connected to the bottom side of the mounting housing 51.

[0079] When the engaging strip 72 is in contact with the follower gear 71 and the rotating gear 63, it engages with both of them respectively.

[0080] In this technical solution, the synchronous locking component 7 can be used to lock the lifting component 5 and the moving component 6 simultaneously, thereby increasing the stability of the lifting component 5 and the moving component 6.

[0081] The mounting housing 51 has multiple sliding holes and slots on its bottom side, and the sliding column 73 moves within the sliding holes and slots.

[0082] One end of each of the sliding posts 73 away from the locking strip 72 is connected to the anti-detachment stabilizing plate 74, and the sliding posts 73 are sleeved on the surface of the drive shaft 62.

[0083] In this technical solution, the anti-detachment stabilizing plate 74 can increase the stability of the movement of structures such as the sliding column 73.

[0084] After the lifting assembly 5 and the moving assembly 6 are adjusted, the locking strip 72 can be pushed inward, thereby driving the sliding column 73 and the anti-detachment stabilizing plate 74 to move in the same direction, so that the locking strip 72 can engage with the rotating gear 63 and the follower gear 71, thereby limiting the angle of the transmission shaft 62 and the threaded shaft 52, and thus locking the lifting assembly 5 and the moving assembly 6.

[0085] When it is necessary to adjust the lifting assembly 5 and the moving assembly 6, simply pull out the locking strip 72 so that the locking strip 72 is away from the rotating gear 63 and the following gear 71 to release the locking of the lifting assembly 5 and the moving assembly 6.

[0086] The bidirectional power source 56 and bidirectional drive source 61 are dual-axis motors or other devices capable of outputting rotational kinetic energy.
