It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Please also read Figures 1 to 3 , the thermal radiation and infrared scanning imaging device provided by the utility model is now described.

The thermal radiation box 5 is mounted on one side of the mounting frame 1, and a light-transmitting hole is provided on the thermal radiation box 5. The connecting plate 6 is mounted on the thermal radiation box 5, and a plurality of through holes 8 with different inner diameters are provided on the connecting plate 6, and each through hole 8 is respectively used to connect with the light-transmitting hole for changing the amount of thermal radiation of the light-transmitting hole. The positioning plate 3 is connected to the mounting frame 1 and is arranged toward the thermal radiation box 5; a horizontal and vertical coordinate system is provided on the positioning plate 3. The sensor is adsorbed on the positioning plate 3 and is located between the positioning plate 3 and the thermal radiation box 5 for determining the amount of thermal radiation and infrared scanning imaging; the sensor is used to be positioned at a specified position of the positioning plate 3 with the aid of the coordinate system.

[0028] The beneficial effect of the thermal radiation and infrared scanning imaging device provided by the utility model is that: compared with the prior art, in the thermal radiation and infrared scanning imaging device of the utility model, the thermal radiation box 5 is installed on one side of the mounting frame 1, and a light-transmitting hole is provided on the thermal radiation box 5. The connecting plate 6 is installed on the thermal radiation box 5, and a plurality of through holes 8 with different inner diameters are opened on the connecting plate 6. The positioning plate 3 is connected to the mounting frame 1 and is arranged toward the thermal radiation box 5, and a horizontal and vertical coordinate system is provided on the positioning plate 3. The sensor is adsorbed on the positioning plate 3 and is located between the positioning plate 3 and the thermal radiation box 5.

[0029] In actual application, since a horizontal and vertical coordinate system is provided on the positioning plate 3, the sensor can be adjusted to a specified position through the coordinate system, and the heat radiation amount of the light-transmitting hole can be changed by connecting the through holes 8 with different inner diameters to the light-transmitting hole. The device provided by the present application is easy to operate, has a relatively simple structure, and is easy to carry.

[0030] In some embodiments of the thermal radiation and infrared scanning imaging device provided in this application, please refer to Figure 1 , the positioning plate 3 is vertically plugged into the mounting frame 1. The positioning plate 3 is adsorbed with a sensor, and the sensor itself needs to be vertically set on the positioning plate 3. When the position of the positioning plate 3 is determined, the position of the sensor is also determined. In the actual application process, it is necessary to adjust the position of the sensor relative to the positioning plate 3 many times. For the convenience of operation, the positioning plate 3 can be removed from the mounting frame 1 first, and then inserted into the mounting frame 1 after the sensor is positioned at the specified position.

[0031] In some embodiments of the thermal radiation and infrared scanning imaging device provided in this application, please refer to Figure 1 , a mounting seat 2 is slidably provided on the mounting frame 1, and a card slot is provided on the mounting seat 2 to be plugged with the positioning plate 3. The top of the mounting seat 2 is open, and the mounting seat 2 can be regarded as a U-shaped structure. The bottom of the mounting frame 1 is fixed on the mounting seat 2, and a card slot is provided on the top. In actual application, the positioning plate 3 can be directly inserted into the card slot to achieve the positioning of the sensor. By sliding the mounting seat 2, the distance between the mounting seat 2 and the heat radiation box 5 can be adjusted.

[0032] In some embodiments of the thermal radiation and infrared scanning imaging device provided in the present application, a permanent magnet is fixed to the end of the sensor, and the sensor is adsorbed on the positioning plate 3 with the help of the permanent magnet. The sensor needs to be stably adsorbed on the positioning plate 3. In order to achieve the above-mentioned technical effect, a permanent magnet is fixed to the end of the sensor, and the permanent magnet can be directly bonded to the sensor. At the same time, the positioning plate 3 is made of a magnetic metal material, which facilitates the adsorption of the permanent magnet. The coordinate system is set on the side of the positioning plate 3 facing the thermal radiation box 5, and the horizontal axis is set horizontally and the vertical axis is set vertically for easy identification.

[0033] In some embodiments of the thermal radiation and infrared scanning imaging device provided in the present application, a protective cover is buckled on the mounting frame 1. In order to ensure the accuracy of each imaging, that is, not to be affected by the surrounding environment, in the actual operation process, the protective cover needs to be buckled on the mounting frame 1, at which time the protective cover can be placed in a relatively closed environment. The protective cover itself is made of opaque material, and an operating door is hinged on the top of the protective cover, through which the sensor and the thermal radiation box 5 can be adjusted to a certain extent.

[0034] In some embodiments of the thermal radiation and infrared scanning imaging device provided in the present application, a temperature regulator is provided on the outside of the protective cover. In order to further ensure the accuracy of the final measurement, that is, to avoid the influence of the surrounding environment on the imaging result, a temperature regulator can be provided on the outside of the protective cover. First, the protective cover itself is made of heat-conducting material, and the temperature of the protective cover is adjusted by the temperature regulator, and finally the temperature of the space between the protective cover and the mounting frame 1 is adjusted by the protective cover.

[0035] In an embodiment, the temperature regulator may be a semiconductor cooling sheet. In practical application, a plurality of semiconductor cooling sheets may be attached to each side of the protective cover, and the temperature may be adjusted through unified control.

[0036] In some embodiments of the thermal radiation and infrared scanning imaging device provided in this application, please refer to Figure 1 and Figure 2 , a calibration component is provided on the positioning plate 3, and the calibration component is used to display the position of the sensor. A sensor is provided on the positioning plate 3. More importantly, the position of the sensor relative to the positioning plate 3 needs to be adjusted multiple times according to preset requirements. If there are no other limiting measures, it is necessary to ensure the accuracy of the position by visual inspection. However, it should be pointed out that the coordinate system may be far away from the position of the sensor. If there is no auxiliary positioning tool, it is difficult to place the sensor in the correct position. Based on the above reasons, a calibration component is provided on the positioning plate 3, and the calibration component can effectively read the coordinates of the sensor in the coordinate system at this time, thereby ensuring the accuracy of the position.

[0037] In some embodiments of the thermal radiation and infrared scanning imaging device provided in this application, please refer to Figure 1 and Figure 2, the calibration assembly includes a first rod 11 and a second rod 4 which is arranged perpendicular to the first rod 11; the first rod 11 and the second rod 4 are respectively slidably arranged on the positioning plate 3 and are respectively parallel to the X-axis and the Y-axis of the coordinate system. To explain in more detail, the calibration assembly consists of the first rod 11 and the second rod 4, and the first rod 11 and the second rod 4 are perpendicular. In the actual operation process, it is necessary to enable the first rod 11 and the second rod 4 to slide in a plane parallel to the positioning plate 3, and the first rod 11 and the second rod 4 to abut against the sensor. Since the first rod 11 and the second rod 4 are respectively parallel to the X-axis and the Y-axis of the coordinate system, by making the first rod 11 and the second rod 4 abut against the sensor and taking readings, the position of the sensor in the coordinate system and the corresponding readings can be read relatively quickly and accurately, thereby ensuring the accuracy of the final result.

[0038] In some embodiments of the thermal radiation and infrared scanning imaging device provided in this application, please refer to Figure 1 and Figure 2 , a first groove 10 and a second groove 9 are respectively provided along the side of the positioning plate 3, and the first rod 11 and the second rod 4 are respectively slidably arranged in the first groove 10 and the second groove 9. In order to explain in more detail, that is, to clarify the positions of the first rod 11 and the second rod 4 relative to the positioning plate 3, the first groove 10 and the second groove 9 are respectively opened on the vertical side edges of the positioning plate 3, the first groove 10 and the second groove 9 are vertically arranged, and the first rod 11 and the second rod 4 are respectively slidably arranged in the first groove 10 and the second groove 9, and can be prevented from slipping out of the groove by connecting nuts and the like. The first rod 11 is arranged to avoid the second rod 4, that is, the distance between the second rod 4 and the positioning plate 3 is greater than the distance between the first rod 11 and the positioning plate 3.

[0039] In some embodiments of the thermal radiation and infrared scanning imaging device provided in this application, please refer to Figure 3 , the connecting plate 6 is rotatably arranged on the heat radiation box 5; the ball head is connected with a support rod 7 between the heat radiation box 5 and the mounting frame 1. A rotating shaft is fixed on the heat radiation box 5, and the connecting plate 6 is rotatably arranged on the rotating shaft, and in order to facilitate the change of the position of the heat radiation box 5, a support rod 7 is connected between the heat radiation box 5 and the mounting frame 1, and the bottom end of the support rod 7 is connected to the ball head of the mounting plate, and the top end is connected to the ball head of the heat radiation box 5.
