Description

Technical Field

[0001] This utility model relates to the field of high-voltage power equipment technology, and more specifically, to an explosion-proof magnetic lock infrared temperature measurement window. Background Technology

[0002] A temperature measurement window is an optical component that transmits visible light, infrared light, and ultraviolet light. By installing the infrared window on the casing of electrical cabinets such as high-voltage electrical cabinets and high-voltage switchgear, various non-destructive tests can be easily performed on the internal equipment of the electrical cabinet. This greatly facilitates online infrared inspection, improves the maintenance efficiency of power equipment, and ensures the safe operation of the equipment.

[0003] Currently, the method for detecting heat in high-voltage electrical cabinets, high-voltage switchgear, and other equipment is to use infrared detection equipment to measure the internal heat of the high-voltage electrical cabinet through an observation window that can transmit infrared waves. However, the surface of the infrared temperature measurement window is neither conductive nor has any grounding device. Therefore, the infrared temperature measurement window is installed on the switchgear (the switchgear door has good grounding), which cannot meet the requirements of good grounding. In addition, the existing infrared temperature measurement window does not have an explosion-proof cover, which cannot effectively resist arcing and protect the optical lens and personal safety. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an explosion-proof magnetic lock infrared temperature measurement window that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows:

[0006] This utility model provides an explosion-proof magnetic lock infrared temperature measurement window, including a flange frame. An installation ring is installed on the flange frame via an external thread. The installation ring has two first M4 grounding threaded holes that are symmetrically opened from front to back. A first M4 set screw is installed on the installation ring via the first M4 grounding threaded holes.

[0007] In a preferred embodiment, two second M4 grounding threaded holes are symmetrically provided on the flange bracket, and a second M4 set screw is installed on the flange bracket through the second M4 grounding threaded holes.

[0008] In a preferred embodiment, a rotating pin is rotatably fitted onto the flange frame, a cover is rotatably fitted onto the surface of the rotating pin, and a first spring pin is installed through the end face of the rotating pin, the first spring pin being in contact with the cover.

[0009] In a preferred embodiment, an explosion-proof cover is fixedly fitted onto the surface of the rotating pin, and the explosion-proof cover and the cap are respectively located at both ends of the flange frame.

[0010] In a preferred embodiment, the explosion-proof cover has two symmetrically arranged limiting holes about the axis of the rotating pin, and the flange bracket is fitted with a limiting pin on the side near the explosion-proof cover.

[0011] In a preferred embodiment, the cover has an arc-shaped groove, which is arranged in a ring around the center of the rotating pin, and the first spring pin is in contact with the inner wall of the arc-shaped groove.

[0012] In a preferred embodiment, the side wall of the flange frame is provided with a third M4 grounding threaded hole, and a second spring pin is installed on the flange frame through the third M4 grounding threaded hole.

[0013] In a preferred embodiment, the surface of the rotating pin is provided with an annular groove, and the second spring pin contacts the inner wall of the annular groove.

[0015] 1. By setting the first M4 set screw, the user can install the first M4 set screw through the first M4 grounding threaded hole, so that the first M4 set screw comes into contact with the cabinet.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-4 This utility model provides a technical solution: an explosion-proof magnetic lock infrared temperature measurement window, including a flange frame 1. An mounting ring 2 is installed on the flange frame 1 via an external thread. Two mounting holes are symmetrically opened on the mounting ring 2. Two first M4 grounding threaded holes are symmetrically opened on the mounting ring 2, extending from front to back. A first M4 set screw 3 is installed on the mounting ring 2 through the first M4 grounding threaded holes. By setting the first M4 set screw 3, a user can use a 110mm hole saw to drill a 110mm diameter circular hole in the cabinet door of the high-voltage switchgear, and then rotate the mounting ring 2 to... Remove the mounting ring 2, insert the end of the flange bracket 1 with the external thread into the round hole, and thread the mounting ring 2 onto the flange bracket 1 again through the mounting hole. At this time, the cabinet door of the high-voltage switchgear is clamped between the end face of the flange bracket 1 and the mounting ring 2. The user then installs the first M4 set screw 3 through the first M4 grounding threaded hole, so that the first M4 set screw 3 contacts the cabinet body. The set screw breaks the insulation layer on the surface of the cabinet body and contacts the metal, thereby achieving the grounding effect. The first M4 set screw 3 can further improve the fixing effect of the mounting ring 2.

[0025] Reference Figures 1-4 Two second M4 grounding threaded holes are symmetrically opened on the flange bracket 1. A second M4 set screw 4 is installed on the flange bracket 1 through the second M4 grounding threaded hole. By setting the second M4 set screw 4, when the flange bracket 1 is installed on the high voltage switchgear, the second M4 set screw 4 is installed through the second M4 grounding threaded hole, thereby achieving the grounding effect of the flange bracket 1 and the switchgear.

[0026] Reference Figures 1-4A rotating pin 5 is rotatably mounted on the flange bracket 1, and a cover 6 is rotatably mounted on the surface of the rotating pin 5. A first spring pin 7 is installed through the end face of the rotating pin 5. The first spring pin 7 is in contact with the cover 6. By setting the rotating pin 5, the user can rotate the rotating pin 5. Since the diameter of the cover 6 is the same as the diameter of the flange bracket 1, when the two are rotated to be completely overlapped, the cover 6 can cover and protect the flange bracket 1.

[0027] Reference Figures 1-4 An explosion-proof cover 8 is fixedly fitted onto the surface of the rotating pin 5. The explosion-proof cover 8 and the cover 6 are located at the two ends of the flange frame 1, respectively. Two limiting holes 9 are symmetrically opened on the explosion-proof cover 8 with the rotating pin 5 as the axis. A limiting pin 10 is installed on the side of the flange frame 1 near the explosion-proof cover 8 to limit the rotation angle of the explosion-proof cover 8. Since the explosion-proof cover 8 is provided with a stepped hole, the end of the rotating pin 5 is inserted into the interior of the stepped hole. When the rotating pin 5 rotates, it drives the explosion-proof cover 8 to rotate together. By setting the explosion-proof cover 8, the diameter of the explosion-proof cover 8 is the same as the diameter of the flange frame 1, thereby shielding the flange frame 1, playing a role in preventing arcing, and preventing damage to the surrounding environment and personal safety when the optical lens explodes due to high temperature. When it is necessary to open the explosion-proof cover 8, simply rotate the rotating pin 5 to drive the explosion-proof cover 8 and the flange frame 1 to be misaligned.

[0028] Reference Figures 1-4 The cover 6 has an arc-shaped groove 11, which is arranged in a ring around the center of the rotating pin 5. The first spring pin 7 is in contact with the inner wall of the arc-shaped groove 11. By setting the arc-shaped groove 11, the first spring pin 7 on the rotating pin 5 is always in contact with the cover 6 when the rotating pin 5 is rotated.

[0029] Reference Figures 1-4 The side wall of the flange bracket 1 is provided with a third M4 grounding threaded hole. A second spring pin 12 is installed on the flange bracket 1 through the third M4 grounding threaded hole. An annular groove 13 is provided on the surface of the rotating pin 5. The second spring pin 12 contacts the inner wall of the annular groove 13. By setting the annular groove 13 and the second spring pin 12, the user can thread the second spring pin 12 into the third M4 grounding threaded hole until the second spring pin 12 contacts the inner wall of the annular groove 13, thereby further fixing the rotating pin 5.

[0030] Specifically, the working process or principle of this explosion-proof magnetic lock infrared temperature measurement window is as follows: When in use, the user uses a 110mm hole saw to make a 110mm diameter round hole on the cabinet door of the high-voltage switchgear. The user rotates the mounting ring 2 to remove the mounting ring 2, inserts the end of the flange bracket 1 with external threads into the round hole, and threads the mounting ring 2 back onto the flange bracket 1 through the mounting hole. At this time, the cabinet door of the high-voltage switchgear is clamped between the end face of the flange bracket 1 and the mounting ring 2. The user then installs the first M4 set screw 3 through the first M4 grounding threaded hole, making the first M4 set screw 3 contact the cabinet body. The user then installs the second M4 set screw 4 through the second M4 grounding threaded hole, inserts the rotating pin 5 into the flange bracket 1, connects the rotating pin 5 and the cover 6 through the first spring pin 7, and fixes the rotating pin 5 through the second spring pin 12.
