Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figures 1-4 As shown, this utility model provides a technical solution: an adjustable knife switch status detection device for switchgear, comprising: The mounting backplate 1 is installed, and a mounting bracket 11 is welded to the outer wall of the mounting backplate 1. The knife switch body 12 is detachably connected to the side of the mounting bracket 11 away from the mounting backplate 1. Adjustable status detection mechanism 2 is installed on the mounting back plate 1. Adjustable status detection mechanism 2 is used to detect the closing position of the disconnector body 12. Temperature detection mechanism 3 is installed on the outer wall of the mounting back plate 1. Temperature detection mechanism 3 is used to detect the temperature of the knife switch body 12. The adjustable state detection mechanism 2 includes a connecting beam 21. A connecting block 22 is detachably connected to one end of the connecting beam 21. A light emitter 23 is fixedly mounted on the side of the connecting block 22. A connecting block 24 is detachably connected to the end of the connecting beam 21 away from the connecting block 22. A light receiver 25 is fixedly mounted on the side of the connecting block 24. A kit 26 is fixedly fitted onto the outer wall of the connecting beam 21. Through the design of the connecting beam 21, connecting block 22, and connecting block 24, the light emitter 23 and the light receiver 25 are fixedly connected. During production, the corresponding positions of the light emitter 23 and the light receiver 25 can be maintained. Therefore, during installation, there is no need for light aiming adjustments, simplifying the installation process and improving installation efficiency. The connecting block 22 is mounted on the connecting beam 21 with bolts, and the connecting block 24 is mounted on the connecting beam 21 with screws. The bolt is installed on the connecting beam 21. If either the light transmitter 23 or the light receiver 25 is damaged, it can be replaced accordingly. During use after accurate installation, the light emitted by the light transmitter 23 will be blocked by the gate of the knife switch body 12. When the gate of the knife switch body 12 is misaligned, causing poor contact, the blocking of the light transmitter 23 will be released, and the light receiver 25 will receive the light, thereby triggering an alarm. The light transmitter 23 and the light receiver 25 are existing technologies, and their structures have not been modified in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them skillfully. Therefore, this paper will not elaborate on them further, such as the light emission module and light receiving module involved in the patent with publication number CN204516623U.

[0016] As one implementation method in this embodiment, such as Figure 3 As shown, the adjustable state detection mechanism 2 also includes a support rod 27, which is fixedly installed on the inner wall of the mounting back plate 1. A fixed frame 271 is fixedly installed at the end of the support rod 27 away from the inner wall of the mounting back plate 1. A movable part 272 is detachably connected to the inner cavity of the fixed frame 271. A bolt No. 1 is threadedly connected to the outer wall of the fixed frame 271. The threaded end of the bolt No. 1 movably abuts against the outer wall of the movable part 272. When adjusting the front and rear position of the connecting beam 21 as a whole, first loosen the bolt No. 1 on the fixed frame 271, and then slide the movable part 272 back and forth in the inner cavity of the fixed frame 271. After the adjustment is completed, tighten the bolt No. 1.

[0017] As one implementation method in this embodiment, such as Figure 3 As shown, a frame 28 is fixedly installed at the end of the movable part 272. A vertical rod 281 is fixedly installed between the top and bottom of the inner wall of the frame 28. A lifting sleeve 282 is slidably connected to the outer wall of the vertical rod 281. By sliding the lifting sleeve 282 on the outer wall of the vertical rod 281, the overall height of the connecting beam 21 can be adjusted.

[0018] As one implementation method in this embodiment, such as Figure 3 As shown, the side thread of the lifting sleeve 282 is connected with a No. 2 bolt. The threaded end of the No. 2 bolt is in movable contact with the outer wall of the upright 281. The kit 26 is fixedly installed at the end of the lifting sleeve 282. If it is necessary to adjust the overall height of the connecting beam 21, first loosen the No. 2 bolt, then adjust it. After the adjustment is completed, tighten the No. 2 bolt.

[0019] As one implementation method in this embodiment, such as Figure 4 As shown, the temperature detection mechanism 3 includes a strip frame 31, which is fixedly installed on the outer wall of the mounting back plate 1. A movable strip 33 is movably inserted into the inner cavity of the strip frame 31. A magnetic block 32 is fixedly installed on the inner wall of the strip frame 31, and the magnetic block 32 and the movable strip 33 are magnetically connected. An internally threaded cylinder 34 is fixedly installed on the outer wall of the movable strip 33, and a connector 35 is threadedly connected to the inner wall of the internally threaded cylinder 34. Through the design of the strip frame 31, the magnetic block 32, the movable strip 33, the internally threaded cylinder 34, and the connector 35, the user can detect infrared temperature. The number of sensors 37 can be designed to be 0-3. When no infrared temperature sensor 37 is set, the movable strip 33 does not need to be installed. When 1-3 infrared temperature sensors 37 are set, the movable strip 33 is inserted into the inside of the strip frame 31. At this time, the magnetic block 32 will magnetically attract and fix the movable strip 33. Then, the corresponding number of connectors 35 can be rotated and installed in the internal threaded cylinder 34. In this way, the number of temperature measurement points on the knife switch body 12 can be designed. For knife switch bodies 12 that are inconvenient to measure temperature, the number of temperature measurement points can be reduced, thus reducing costs.

[0020] As one implementation method in this embodiment, such as Figure 4As shown, a gooseneck bar 36 is fixedly installed at the end of the connector 35. An infrared temperature sensor 37 is fixedly installed at the end of the gooseneck bar 36 away from the connector 35. The design of the gooseneck bar 36 allows for bending to adjust the position of the infrared temperature sensor 37, enabling adjustment of the temperature measurement position on the switch body 12 and improving operational flexibility. The temperature data detected by the infrared temperature sensor 37 is fed back to the controller, which can be installed on the outer wall of the internally threaded cylinder 34. When a threshold is exceeded, the controller activates the alarm device to provide a warning. It is worth noting that the infrared temperature sensor 37 and the controller in this solution are the work of those skilled in the art. The equipment can be purchased commercially, and its structure has not been modified in this paper. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it proficiently. Thus, this paper will not elaborate on it further. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposed processing circuit is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electronic control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0021] Working principle: The design of connecting beam 21, connecting block 1 22, and connecting block 24 fixes the light transmitter 23 and light receiver 25 together. During production, the corresponding positions of the light transmitter 23 and light receiver 25 are maintained. Therefore, during installation, there is no need to perform light aiming adjustment, simplifying the installation process. During assembly, the knife switch body 12 is installed on the mounting bracket 11, and then the overall position of the light transmitter 23 and light receiver 25 is adjusted back and forth and up and down to adapt to the position of the shutter on the knife switch body 12. In use, the light emitted by the light transmitter 23 will be blocked by the shutter on the knife switch body 12. When the shutter on the knife switch body 12 shifts and causes poor contact, it will release the blocking of the light transmitter 23, and the light receiver 25 will receive the light, thus triggering an alarm.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
