Description

Technical Field

[0001] The utility model relates to the technical field of radiation temperature measurement of distribution equipment, in particular to a magnetic lock type full-band multi-spectral temperature measurement window. Background Technique

[0002] At present, for equipment such as high-voltage switch cabinets and high-voltage switchboards, the means of heat detection is to use infrared detection equipment to measure the internal heat condition of the high-voltage switch cabinet through an observation window that can transmit the infrared band. The temperature measurement window is an optical component that can transmit visible light, infrared rays, and ultraviolet rays. The infrared window is installed on the shell of electrical cabinets such as high-voltage switch cabinets and high-voltage switchboards, so that various non-destructive detections of the internal equipment of the electrical cabinet can be conveniently carried out through the infrared temperature measurement window, which greatly facilitates on-line infrared detection, improves the maintenance efficiency of power equipment, and ensures the safe operation of the equipment.

[0003] The magnetic buckle design makes the opening and closing of the protective cover more convenient. When temperature measurement is required, maintenance personnel can easily open the protective cover and quickly carry out observations and internal inspections, which brings great convenience to the temperature measurement work of electrical equipment. At the same time, due to the environment where the temperature measurement window is located and the frequent opening of the protective cover, the magnets on the protective cover and the window body will loosen to varying degrees, affecting the opening and closing of the protective cover and failing to effectively prevent foreign objects from entering the window, affecting the accuracy of measurement data. During the closing process of the protective cover, due to the suction force of the magnet, when the protective cover is completely closed, there is a certain impact force on the window body, causing loosening of the window body or damage to the optical lens. The temperature measurement window is installed on the high-voltage switchboard, and it is inevitable that the optical lens will be damaged during long-term use. Since it is installed on the live high-voltage cabinet, the installation difficulty during power outage is large and the waiting period is long, and it is not easy to replace the optical lens.

Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a magnetic lock type full-band multi-spectral temperature measurement window, including a flange frame 2. The flange frame 2 is arranged in a stepped circular ring shape. The inner wall of the ring hole of the stepped circular ring is provided with an internal thread section 14, and an installation portion 18 is formed at the end with a smaller outer diameter away from the outer cover 1. The inner wall of the port of the installation portion 18 is integrally formed with an annular limiting piece 19, and the inner diameter of the limiting piece 19 is smaller than the inner diameter of the ring hole of the stepped circular ring.

[0029] The glass lens 17 is screwed into the internal thread section 14 until it touches the limiting piece 19. The inner ring 12 is screwed into the internal thread section 14, and the inner ring 12 abuts against the edge of the glass lens 17 for fixation.

[0030] That is, by changing the existing lens fixing and installation method, the temperature measurement window can rotate, replace, and remove the lens even when energized, for quick maintenance.

[0031] In order to reduce the maintenance and replacement frequency of the glass lens 17:

[0032] On one side of the flange frame 2, an outer cover 1 for opening and closing the end window is rotatably connected. A magnetic absorption buffer component is arranged between the joint surfaces of the outer cover 1 and the flange frame 2, including at least three magnet blocks asymmetrically arranged on the outer cover 1 and the flange frame 2. Two of the mutually contacting magnet blocks repel each other, and the impact force during the rotational sealing contact of the outer cover 1 is reduced through the repulsive force.

[0033] Specific description: A counterbore 4 is opened on the edge of the outer cover 1, and a first threaded hole 7 corresponding to the counterbore 4 is opened on the edge of the flange frame 2. The outer cover 1 is threadedly connected to the first threaded hole 7 through a rotating pin 13 passing through the counterbore 4. The outer cover 1 rotates on the flange frame 2 with the rotating pin 13 as the pivot point. That is, the rotating outer cover 1 is arranged to seal and open / close the ring hole of the flange frame 2, and the ring hole is opened or sealed by rotation.

[0034] In this embodiment, the rotating pin 13 is set as a bolt. A threaded section is arranged at the tail end of the bolt rod, and the part near the bolt head is a smooth rod body. Therefore, the threaded section of the rod of the rotating pin 13 is threadedly installed in the first threaded hole 7 of the flange frame 2, the head of the rotating pin 13 is limited at the counterbore 4 of the outer cover 1, and the smooth rod section of the rotating pin 13 is used for the unobstructed rotation of the outer cover 1.

[0035] It should be noted that: after the rotating pin 13 is fully installed, there is a slight gap between the bolt head and the port of the counterbore 4, which will not overly fasten the outer cover 1, ensuring the smooth rotation of the outer cover 1.

[0036] In this way, the infrared temperature measurement window is provided with a rotating bolt fixing screw, which can prevent the outer cover 1 from loosening and falling off after multiple rotations. The rotational limit constraint can be achieved by quickly twisting the rotating pin 13, which is convenient and practical.

[0037] It should be noted that: the above bolt is a mature product on the market and is relatively common, and is not shown in the drawings of this application.

[0038] The magnetic absorption buffer assembly includes magnet block two 9 and magnet block three 10 which are adjacently inlaid on the edge of the end face of flange frame 2. Magnet block one 6 is inlaid on the edge of outer cover 1 corresponding to magnet block two 9. When outer cover 1 rotates to the same axis as flange frame 2, the central positions of magnet block one 6 and magnet block two 9 are 1 - 3 mm apart and have repulsive magnetism.

[0039] Setting multiple asymmetric magnet blocks at the window can effectively prevent the magnets from falling off and avoid affecting the magnetic absorption opening and closing of the lid. In addition, by setting reverse-acting magnet blocks, the impact caused by frequent opening of the lid is eliminated, and the loosening of the lens inside the window is improved.

[0040] As a further improvement of this embodiment, for the convenience of closing and using outer cover 1:

[0041] The bottom edge of flange frame 2 is integrally connected with a limit seat 11, which is in an arc structure and has an upper opening forming an arc groove. When outer cover 1 rotates to cover the window of flange frame 2, the bottom of outer cover 1 is inserted and abutted into the arc groove to limit the rotation position, facilitating the rotation and sealing of the window by outer cover 1.

[0042] In this embodiment, a stepped hole is opened on outer cover 1, and a threaded hole two 8 is opened on the end face of flange frame 2 corresponding to the stepped hole. On outer cover 1, fastening screw 5 passes through the stepped hole and is threadedly connected to threaded hole two 8 for screw fixation when outer cover 1 seals the window.

[0043] Among them, fastening screw 5 is set as a riveting plum blossom screw, which is convenient for using tools to unscrew.

[0044] That is, a riveting plum blossom screw is provided at the temperature measurement window, enhancing the explosion-proof ability of outer cover 1.

[0045] As a further improvement of this embodiment, for the convenience of installation and use of the temperature measurement window:

[0046] The outer diameter of the installation part 18 at one end of flange frame 2 away from outer cover 1 is smaller than the outer diameter of the ring body at the window of flange frame 2. An annular outer ring 3 is threadedly installed on installation part 18. Multiple threaded holes three 15 and threaded through holes 16 are opened on outer ring 3, and corresponding installation holes for combined fixation are opened on flange frame 2 for fixation during installation with screws.

[0047] A threaded through hole 10 is provided on the side of the above-mentioned outer ring 3, and the flange frame 2 is connected through the threaded through hole 10 by a screw to make outer ring 2 communicate with flange frame 2; a fixing screw hole 9 is provided on the end face of outer ring 3 to prevent outer ring loosening by contacting the surface of the cabinet through fixing screw hole 9.

[0048] The installation process of the present utility model:

[0050] 1. Use a hole cutter with a diameter of 110 mm to cut a round hole with a diameter of 110 mm;

[0051] 2. Remove the outer ring 3 of the infrared temperature measurement window, insert the flange frame 2 into the round hole from the outside to the inside, and then screw the outer ring 3 onto the external thread of the installation part 18 of the flange frame 2. At this time, the cabinet door of the high-voltage switchgear cabinet is clamped between the flange frame 2 and the outer ring 3;

[0052] 3. Use a self-tapping screw of M4 to pass through the threaded through-hole 16 and the cabinet door, connect the installation holes on the flange frame 2, and fix the combination of the flange frame 2 and the outer ring 3; use a self-tapping screw of M4 to connect the threaded hole three 15 and the cabinet door to make the outer ring 3 contact the cabinet surface to prevent the outer ring from loosening;

[0053] 4. Screw a rotating pin of M4 into the counterbore 4 and the threaded hole one 7 of the outer cover 1 and the flange frame 2 to connect the outer cover 1 and the flange frame 2 together to complete the rotating connection; use a fastening screw 5 of M4 to screw into the stepped hole and the threaded hole two 8 of the outer cover 1 and the flange frame 2 for explosion-proof fixation.

[0054] In the flange frame 2 of the present utility model, an O-ring nitrile rubber seal with dimensions of 100×3.1 mm is installed, and then an optical glass lens 17 with dimensions of 100×3 mm is placed into the internal thread section 14 of the flange frame 2. O-ring nitrile rubber seals with dimensions of 100×3.1 mm are placed above and below the optical lens, and then the inner ring 12 is screwed into the internal thread section 14 of the flange frame 2 to prevent the optical lens from loosening in the internal thread section 14;

[0055] When measuring the indoor temperature, the outer cover 1 needs to be opened. Use a plum blossom wrench to turn the riveted plum blossom fastening screw 5 on the cover, and then rotate the outer cover 1 to the fully open position, that is, without blocking the visual path of the temperature measurement window, and observe the internal situation of the equipment through the glass lens 17. After the temperature measurement is completed, rotate and close the outer cover 1 to block the visual path of the temperature measurement window and end the operation.
