[0029] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0030] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure proposes a foreign body detection device for an excitation system, including: a bracket 1, an infrared thermal imager 2 and a processing module (not shown in the figure), the bracket 1 includes: a first base 11, a second base 12, a first positioning assembly, a third base 13 and a second positioning assembly, the first base 11 is arranged on the bearing surface of the area to be measured in the excitation system, and the second base 12 is rotatably arranged on the first base 11 around a first rotation direction, the first positioning assembly is arranged between the first base 11 and the second base 12, the third base 13 is rotatably arranged on the second base 12 around a second rotation direction, the second positioning assembly is arranged between the second base 12 and the third base 13, the first rotation direction and the second rotation direction are at a preset angle, the infrared thermal imager 2 is arranged on the third base 13, and the detection end of the infrared thermal imager 2 is facing the area to be measured, and the communication end of the processing module is connected to the communication end of the infrared thermal imager 2.

[0031] It can be understood that since the second base support 12 is rotatably arranged on the first base support 11 around the first rotation direction, and the first positioning component is arranged between the first base support 11 and the second base support 12, the second base support 12 can adjust the angle around the first rotation direction, and the first positioning component is used to achieve positioning on the first base support 11, and since the third base support 13 is rotatably arranged on the second base support 12 around the second rotation direction, and the second positioning component is arranged between the second base support 12 and the third base support 13, the third base support 13 can adjust the angle around the second rotation direction, and the second positioning component is used to achieve positioning on the second base support 12.

[0032] Moreover, through the cooperation of the first base 11, the second base 12 and the third base 13, the infrared thermal imager 2 can be set on the bearing surface of the area to be measured in the excitation system using the bracket 1, and the angle adjustment in the first rotation direction and the second rotation direction can be achieved, so that the detection end of the infrared thermal imager 2 can be accurately directed to the area to be measured, and the infrared thermal imager 2 can accurately convert the invisible infrared energy emitted by foreign objects in the area to be measured into a visible thermal image. At the same time, since the communication end of the processing module is connected to the communication end of the infrared thermal imager 2, the infrared thermal imager 2 can send the thermal image to the processing module, so that the processing module can be used to process and analyze the foreign objects, thereby realizing the foreign object detection function.

[0033] Therefore, by utilizing the cooperation of the bracket 1, the infrared thermal imager 2 and the processing module, the automatic detection function of foreign objects is realized while avoiding human intervention, thereby effectively improving the detection efficiency and the detection effect, thereby meeting the requirements for safe operation of the excitation system.

[0034] It should be noted that the bracket 1 is used to set the infrared thermal imager 2 on the bearing surface of the area to be measured in the excitation system. For example, the infrared thermal imager 2 is set on the wall near the cabinet in the excitation system, and the detection end of the infrared thermal imager 2 is facing the cabinet door. The specific type of the bracket 1 can be set according to actual needs and is not limited to this.

[0035] Among them, the first base 11 is used to carry the second base 12, the third base 13, the infrared thermal imager 2, etc. The specific type of the first base 11 can be set according to actual needs and is not limited to this. For example, the first base 11 can be a base structure close to U-shaped.

[0036] The second base 12 is used to be set on the first base 11 to carry the third base 13, the infrared thermal imager 2, etc. The specific type of the second base 12 can be set according to actual needs and is not limited to this. For example, the second base 12 can be a base structure close to U-shaped.

[0037] The first positioning assembly is used to position the second base 12 on the first base 11. When the first positioning assembly releases the second base 12, the second base 12 can rotate along the first rotation direction to adjust the angle of the infrared thermal imager 2. When the first positioning assembly positions the second base 12, the second base 12 is fixed to ensure stable operation of the infrared thermal imager 2.

[0038] The third base bracket 13 is used to be set on the second base bracket 12 to carry the infrared thermal imager 2, etc. The specific type of the third base bracket 13 can be set according to actual needs and is not limited to this. For example, the third base bracket 13 can be a base bracket structure close to U-shape, and the two sides of the third base bracket 13 have ear plates connected to the second base bracket 12.

[0039] The second positioning assembly is used to position the third base 13 on the second base 12. When the second positioning assembly releases the third base 13, the third base 13 can rotate along the second rotation direction to adjust the angle of the infrared thermal imager 2. When the second positioning assembly positions the third base 13, the third base 13 is fixed to ensure stable operation of the infrared thermal imager 2.

[0040] The first rotation direction and the second rotation direction can be set according to actual needs without limitation. For example, the first rotation direction and the second rotation direction are perpendicular to each other, the rotation axis of the first rotation direction is parallel to the bearing surface, and the rotation axis of the second rotation direction is parallel to the bearing surface.

[0041] The infrared thermal imager 2 is also called a thermal imager. The infrared thermal imager 2 is used to convert the invisible infrared energy emitted by foreign objects in the detection area into a visible thermal image. For example, the detection end of the infrared thermal imager 2 is facing the cabinet door. When a foreign object is retained in the cabinet, the infrared thermal imager 2 can detect the foreign object in the cabinet and send the converted thermal image to the processing module. The specific type of the infrared thermal imager 2 can be set according to actual needs and is not limited to this.

[0042] The processing module is used for processing and analyzing thermal images, for example: comparing the basic thermal image with the thermal image detected by the infrared thermal imager 2, so as to determine whether there are foreign objects in the test area based on the comparison results. The specific type of the processing module can be set according to actual needs and is not limited to this. For example, the processing module may include: an industrial computer.

[0043] like Figure 1 and Figure 2 As shown, in some embodiments, the bracket 1 also includes: a guide rail 14, the guide rail 14 is arranged on the bearing surface, and the guide rail 14 is provided with a transverse displacement hole 141 arranged along the first straight line direction, the first base support 11 is located on the side of the guide rail 14 close to the bearing surface, the second base support 12 is located on the side of the guide rail 14 away from the bearing surface, and the first positioning component passes through the transverse displacement hole 141.

[0044] It is understandable that, since the first base 11 is located on the side of the guide rail 14 close to the bearing surface, and the second base 12 is located on the side of the guide rail 14 away from the bearing surface, the first positioning assembly passes through the transverse displacement hole 141, so that when the first positioning assembly releases the first base 11 and the second base 12, the first base 11 and the second base 12 can be adjusted in position along the first linear direction, and the second base 12 can be adjusted in angle along the first rotational direction. When the first positioning assembly positions the first base 11 and the second base 12, the second base 12 can be fixed to the first base 11, and the first base 11 and the second base 12 can be fixed to the guide rail 14. Thus, through the cooperation of the first base 11, the second base 12 and the guide rail 14, the infrared thermal imager 2 can achieve angular adjustment in the first rotational direction and the second rotational direction, and can also achieve position adjustment in the first linear direction, so that the detection end of the infrared thermal imager 2 can be accurately oriented.

[0045] It should be noted that the guide rail 14 is used to support the first base support 11, the second base support 12, etc., and is used for adjusting the position of the first base support 11 and the second base support 12 along the first straight line direction. The specific type of the guide rail 14 can be set according to actual needs and is not limited to this. For example, the guide rail 14 is a plate structure arranged along the first straight line direction, and ear plates are provided on both sides of the guide rail 14. Bolt holes for fixing to the bearing surface are provided on the ear plates, and bolt holes for fixing to the bearing surface are also provided at both ends of the guide rail 14.

[0046] The transverse hole 141 is used for the penetration of the first positioning component and for guiding the movement of the first base 11 and the second base 12. The specific type of the transverse hole 141 can be set according to actual needs and is not limited thereto.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the second base 12 is provided with a first rotation hole 121 arranged along the first rotation direction; the first positioning assembly includes: a first bolt 17, the head of the first bolt 17 abuts against the second base 12, and the threaded portion of the first bolt 17 is threadedly provided on the first base 11, and the threaded portion of the first bolt 17 passes through the first rotation hole 121 and the transverse hole 141 in sequence.

[0048] It is understandable that, because the head of the first bolt 17 abuts against the second base 12 and the threaded portion of the first bolt 17 is threadedly disposed on the first base 11, the threaded portion of the first bolt 17 sequentially passes through the first rotation hole 121 and the transverse displacement hole 141. Therefore, when the first bolt 17 is loosened, the first base 11, the second base 12, and the guide rail 14 can be released, thereby enabling the second base 12 to be angularly adjusted along the first rotational direction and the first base 11 and the second base 12 to be positionally adjusted along the first linear direction. Furthermore, when the first bolt 17 is tightened, the second base 12 can be fixed to the first base 11, and the first base 11 and the second base 12 can be fixed to the guide rail 14. Thus, the arrangement of the first bolt 17 on the first base 11, the second base 12, and the guide rail 14 makes the use of the infrared thermal imager 2 more flexible and convenient.

[0049] It should be noted that the first bolt 17 is used for the cooperation between the first base 11, the second base 12 and the guide rail 14 to achieve the angle adjustment of the infrared thermal imager 2, the position adjustment of the infrared thermal imager 2 and the positioning of the infrared thermal imager 2. The specific type of the first bolt 17 can be set according to actual needs and is not limited to this. For example, the first bolt 17 can be a butterfly bolt.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the bracket 1 further includes: a first rotating shaft 15 , the first rotating shaft 15 is disposed on the first base 11 , and the second base 12 is rotatably disposed on the first rotating shaft 15 , and the first rotating shaft 15 passes through the transverse hole 141 .

[0051] It can be understood that since the first rotating shaft 15 is set on the first base support 11, and the second base support 12 is rotatably set on the first rotating shaft 15, the second base support 12 uses the first rotating shaft 15 to realize rotation on the first base support 11, thereby ensuring stable angle adjustment of the second base support 12 on the first base support 11. At the same time, since the first rotating shaft 15 passes through the transverse hole 141, the first base support 11 and the second base support 12 can use the first rotating shaft 15 to realize movement on the guide rail 14, thereby ensuring stable position adjustment of the first base support 11 and the second base support 12 on the guide rail 14.

[0052] It should be noted that the first rotating shaft 15 is used for the rotation setting of the second base support 12 on the first base support 11, and the sliding setting of the first base support 11 and the second base support 12 on the guide rail 14. The specific type of the first rotating shaft 15 can be set according to actual needs and is not limited to this.

[0053] like Figure 1 and Figure 2As shown, in some embodiments, the second base 12 is provided with a second rotation hole 122 arranged along the second rotation direction; the second positioning assembly includes: a second bolt 18, the head of the second bolt 18 abuts against the second base 12, and the threaded portion of the second bolt 18 is threadedly provided on the third base 13, and the threaded portion of the second bolt 18 passes through the second rotation hole 122.

[0054] It is understandable that, because the head of the second bolt 18 abuts against the second base 12, and the threaded portion of the second bolt 18 is threadedly disposed on the third base 13, the threaded portion of the second bolt 18 passes through the second rotation hole 122. Therefore, when the second bolt 18 is loosened, the third base 13 can be released from the second base 12, thereby enabling the third base 13 to be angularly adjusted along the second rotation direction. Furthermore, when the second bolt 18 is tightened, the third base 13 can be fixed to the second base 12. Thus, the arrangement of the second bolt 18 on the third base 13 and the second base 12 makes the use of the infrared thermal imager 2 more flexible and convenient.

[0055] It should be noted that the second bolt 18 is used for the cooperation between the second base 12 and the third base 13 to achieve the angle adjustment and positioning of the infrared thermal imager 2. The specific type of the second bolt 18 can be set according to actual needs and is not limited to this. For example, the second bolt 18 can be a butterfly bolt.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the bracket 1 further includes: a second rotating shaft 16 , the second rotating shaft 16 is disposed on the second base 12 , and the third base 13 is rotatably disposed on the second rotating shaft 16 .

[0057] It can be understood that since the second rotating shaft 16 is set on the second base support 12, and the third base support 13 is rotatably set on the second rotating shaft 16, the third base support 13 uses the second rotating shaft 16 to realize rotation on the second base support 12, thereby ensuring stable angle adjustment of the third base support 13 on the second base support 12.

[0058] It should be noted that the second rotating shaft 16 is used for the rotation of the third base 13 on the second base 12. The specific type of the second rotating shaft 16 can be set according to actual needs and is not limited to this.

[0059] Among them, the second rotating shaft 16 can be set as two groups, respectively arranged between the U-shaped side plate of the second base 12 and the ear plate of the third base 13, and the second bolt 18 is set as one group, arranged between a U-shaped side plate of the second base 12 and an ear plate of the third base 13.

[0060] like Figure 1 and Figure 2 As shown, in some embodiments, the third base 13 is provided with a receiving groove, and the infrared thermal imager 2 is arranged in the receiving groove, and a wiring channel 131 is provided between the infrared thermal imager 2 and the bottom of the receiving groove, and the wiring channel 131 passes through the third base 13.

[0061] It can be understood that since the infrared thermal imager 2 is arranged in the accommodating groove, and a wiring channel 131 is provided between the infrared thermal imager 2 and the bottom of the accommodating groove, the wiring channel 131 passes through the third base 13, so that the infrared thermal imager 2 can be stably set on the third base 13, and the wiring channel 131 can be used to arrange the lines, thereby making the use of the foreign object detection device more flexible and convenient.

[0062] It should be noted that the receiving groove is used to accommodate the infrared thermal imager 2. The specific type of the receiving groove can be set according to actual needs and is not limited to this. For example, the third base 13 of the U-shaped structure forms a U-shaped receiving groove, and the wiring channel 131 is located at the bottom of the receiving groove.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, a plurality of heat dissipation holes 132 are provided on the third base 13 , and the heat dissipation holes 132 are communicated with the receiving groove.

[0064] It can be understood that since multiple heat dissipation holes 132 are provided on the third base 13, and the heat dissipation holes 132 are connected to the receiving groove, the infrared thermal imager 2 can dissipate heat by using the wiring channel 131 while also using the multiple heat dissipation holes 132, thereby ensuring the stable operation of the infrared thermal imager 2.

[0065] It should be noted that the heat dissipation holes 132 are used to dissipate heat for the infrared thermal imager 2. The specific type of the heat dissipation holes 132 can be set according to actual needs and is not limited to this. For example, the heat dissipation holes 132 are arranged on the side panels of the third base 13 of the U-shaped structure.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the third base 13 is provided with a plurality of waist-shaped holes 133 arranged along the second straight line direction; the bracket 1 also includes: a plurality of third bolts 19, the heads of the third bolts 19 abut against the third base 13, and the threaded portions of the third bolts 19 are threadedly provided on the infrared thermal imager 2, and the threaded portions of the third bolts 19 pass through the waist-shaped holes 133.

[0067] It can be understood that since the head of the third bolt 19 abuts against the third base 13, and the threaded portion of the third bolt 19 is threadedly arranged on the infrared thermal imager 2, the threaded portion of the third bolt 19 passes through the waist-shaped hole 133, so that the infrared thermal imager 2 can be fixed on the third base 13 by using the third bolt 19, and at the same time facilitates the disassembly and assembly of the infrared thermal imager 2, making the use of the foreign object detection device more flexible and convenient.

[0068] It should be noted that the third bolt 19 is used to fix the infrared thermal imager 2 on the third base 13. The specific type of the third bolt 19 can be set according to actual needs and is not limited to this.

[0069] Among them, by using the setting of the waist-shaped hole 133, the position of the infrared thermal imager 2 on the third base 13 can be adjusted within a smaller range. The specific type of the waist-shaped hole 133 can be set according to actual needs and is not limited to this.

[0070] In some embodiments, the foreign object detection device further includes: an alarm module, wherein an input end of the alarm module is connected to an output end of the processing module.

[0071] It is understandable that, since the input end of the alarm module is connected to the output end of the processing module, the processing module can use the alarm module to issue an alarm, thereby prompting the operator to deal with the foreign matter problem in a timely manner.

[0072] It should be noted that the alarm module is used to issue alarm information. The specific type of the alarm module can be set according to actual needs and is not limited to this. For example, the alarm module can be an alarm, and the alarm module can be arranged in locations such as the area to be tested and the monitoring platform.
