Description

Technical Field

[0001] This utility model relates to the field of smoke detection technology, specifically a smoke detection and inspection device for fire protection of the main transformer system in a substation. Background Technology

[0002] The smoke detection and inspection device for fire protection of the main transformer system in a substation is a fire protection device used to monitor the smoke concentration in the main transformer area in real time, detect fire hazards at an early stage, and trigger an alarm.

[0003] According to the patent titled "A Split-Type Track Inspection Smoke Detection Device" (Patent Publication No.: CN223019855U, Patent Publication Date: 2025-06-24), the device includes a track plate with an outer metal rail and an inner metal rail at the upper end. A smoke detector is mounted on the upper end of the track plate. In use, the smoke detector slides along the two tracks to detect smoke in different areas. During movement, a protective frame protects the smoke detector from direct external force, thus extending its lifespan. During operation, the protective plate can be rotated downwards to separate it from the protective frame, exposing the smoke detector for easy maintenance. Therefore, this device not only detects smoke in different areas but also protects and maintains the smoke detector, greatly improving ease of use.

[0004] Based on the aforementioned existing technology, current smoke detection and inspection devices for fire protection in substation main transformer systems still have the following problems: Smoke generated in the early stages of a fire, affected by hot air, will first rise and form a smoke layer below the ceiling or above the equipment. However, the height of existing fixed detectors is usually fixed, which means the detectors are either above or below the smoke layer, leading to alarm delays or even failure. Therefore, this invention provides a smoke detection and inspection device for fire protection in substation main transformer systems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a smoke detection and inspection device for fire protection in substation main transformer systems. It solves the following problems with existing smoke detection and inspection devices for fire protection in substation main transformer systems: Smoke generated in the early stages of a fire, influenced by hot air, rises first and forms a smoke layer below the ceiling or above the equipment. However, existing fixed detectors are usually installed at a fixed height, which can cause alarm delays or even failures due to the detectors being positioned above or below the smoke layer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a smoke detection and inspection device for fire protection of a substation main transformer system, comprising a mobile vehicle, wherein a detection mechanism is provided on the top of the mobile vehicle for raising and lowering the detection head to achieve adaptive detection at different heights, and the detection mechanism includes: The lifting unit is located on the top of the mobile vehicle and includes a frame box fixedly installed on the top of the mobile vehicle. A track rod is fixedly installed inside the frame box, and a convex groove is opened inside the track rod. A convex block is slidably installed inside the convex groove. The detector is lifted and lowered by a drive component set inside the frame box to make the convex block slide up and down. A rotating unit is positioned above the convex block and is used to rotate the detector.

[0007] Preferably, the drive assembly includes a rack fixedly mounted on one side of the convex block, a rotating shaft rotatably mounted inside the frame, and a gear fixedly mounted on the surface of the rotating shaft, with the gear meshing with the rack.

[0008] Preferably, a first worm gear is rotatably mounted inside the frame box, and a servo motor is fixedly mounted on the outside of the frame box, with the output end of the servo motor passing through the frame box and fixedly connected to the first worm gear.

[0009] Preferably, a first worm gear is fixedly mounted on the surface of the rotating shaft, and the first worm gear is meshed with the first worm.

[0010] Preferably, the rotating unit includes a fixed plate fixedly installed on the top of the convex block, a ring frame fixedly installed on the top of the fixed plate, a rotating column rotatably installed in the middle of the top of the fixed plate, a rotating plate fixedly installed at the top of the rotating column, and a smoke detector fixedly installed on the top of the rotating plate. The rotation of the smoke detector is achieved by rotating the rotating column and the rotating plate.

[0011] Preferably, a second worm gear is fixedly installed on the surface of the rotating column, and a second worm is rotatably installed inside the ring frame. A micro motor is fixedly installed on the outside of the ring frame, and the output end of the micro motor passes through the ring frame and is fixedly connected to the second worm. The second worm is meshed with the second worm gear.

[0012] This utility model provides a smoke detection and inspection device for fire protection in the main transformer system of a substation. Compared with the prior art, it has the following advantages: 1. The smoke detection and inspection device for fire protection of the main transformer system in this substation uses a servo motor to drive the first worm gear to rotate. The first worm gear meshes with the first worm wheel, causing the shaft and gear to rotate. The gear meshes with the rack, causing the convex block to slide up and down in the convex groove of the track rod, thereby raising or lowering the rotating unit and the smoke detector. This ensures that the detector can be accurately located in the smoke layer, avoiding alarm delays or failures caused by a fixed height, improving the timeliness and accuracy of fire detection, and enhancing the fire safety of the main transformer system in the substation.

[0013] 2. The smoke detection and inspection device for the main transformer system of this substation uses a micro motor to drive the second worm gear to rotate. The second worm gear meshes with the second worm wheel, causing the rotating column to rotate. The rotating column drives the rotating plate and the smoke detector to rotate, performing multi-directional smoke detection. This allows the detector to cover a wider area. Combined with the lifting function, it further enhances the environmental adaptability of the device, ensuring the rapid detection of fire hazards in the main transformer system of the substation and improving the overall fire protection efficiency and reliability.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: A smoke detection and inspection device for fire protection of a substation main transformer system includes a mobile vehicle 1. A detection mechanism 2 is installed on the top of the mobile vehicle 1 to raise and lower the detection head, enabling adaptive detection at different heights. The detection mechanism 2 includes: The lifting unit 21 is located on the top of the mobile vehicle 1 and includes a frame box 211 fixedly installed on the top of the mobile vehicle 1. A track rod 212 is fixedly installed inside the frame box 211, and a convex groove 213 is opened inside the track rod 212. A convex block 214 is slidably installed inside the convex groove 213. The convex block 214 is slid up and down by the drive component 3 set inside the frame box 211 to realize the lifting of the detector. The rotating unit 22 is disposed above the convex block 214 and is used to realize the rotation of the detector.

[0018] In this embodiment, the drive assembly 3 includes a rack 31 fixedly installed on one side of the convex block 214, a rotating shaft 32 rotatably installed inside the frame box 211, and a gear 33 fixedly installed on the surface of the rotating shaft 32, and the gear 33 meshes with the rack 31.

[0019] The meshing installation of rack 31 and gear 33 enables the convex block 214 to slide up and down, thereby providing a reliable transmission mechanism for lifting unit 21 and ensuring that smoke detector 4 can be raised and lowered smoothly.

[0020] In this embodiment, a first worm gear 36 is rotatably mounted inside the frame box 211, and a servo motor 35 is fixedly mounted on the outside of the frame box 211. The output end of the servo motor 35 passes through the frame box 211 and is fixedly connected to the first worm gear 36.

[0021] The servo motor 35 is model EDSMT-2T110-020A. The servo motor 35 drives the first worm gear 36 to rotate, providing the power source for the lifting unit 21. The first worm gear 36 makes the transmission smoother and more self-locking, preventing accidental slippage during the lifting process.

[0022] In this embodiment, a first worm gear 34 is fixedly mounted on the surface of the rotating shaft 32, and the first worm gear 34 is meshed with the first worm 36.

[0023] The meshing installation of the first worm gear 34 and the first worm 36 converts the rotational motion of the servo motor 35 into the rotation of the shaft 32, which in turn drives the rack 31 through the gear 33, thus realizing the precise control of the lifting unit 21.

[0024] In this embodiment, the rotating unit 22 includes a fixed plate 221 fixedly installed on the top of the convex block 214. A ring frame 222 is fixedly installed on the top of the fixed plate 221, and a rotating column 223 is rotatably installed in the middle of the top of the fixed plate 221. A rotating plate 227 is fixedly installed at the top of the rotating column 223, and a smoke detector 4 is fixedly installed at the top of the rotating plate 227. The rotation of the smoke detector 4 is achieved by rotating the rotating column 223 and the rotating plate 227.

[0025] The smoke detector 4 can be rotated by the fixed plate 221 installed on the top of the convex block 214 and the rotating column 223 connected to the rotating plate 227, thereby realizing multi-angle detection, expanding the monitoring range, and improving the comprehensiveness and flexibility of smoke detection.

[0026] The smoke detector 4 contains a light-emitting element and a photodetector. Under normal circumstances, the light emitted by the LED does not shine directly onto the photosensitive element. When smoke enters the detection chamber, the smoke particles scatter the light, causing some of the light to refract onto the photosensitive element, thus triggering the alarm.

[0027] In this embodiment, a second worm gear 224 is fixedly installed on the surface of the rotating column 223, and a second worm 226 is rotatably installed inside the ring frame 222. A micro motor 225 is fixedly installed on the outside of the ring frame 222, and the output end of the micro motor 225 passes through the ring frame 222 and is fixedly connected to the second worm 226. The second worm 226 is meshed with the second worm gear 224.

[0028] The micro motor 225, model KV3SF-8521F-WR, is electrically connected to an external power supply and is operated by a human-controlled control panel. The micro motor 225 drives the second worm gear 226 to rotate. The second worm gear 226 meshes with the second worm wheel 224, which drives the rotating column 223 to rotate, thereby realizing the smooth rotation of the smoke detector 4, ensuring the accuracy and self-locking of the rotation, and preventing the detector from shaking when it stops.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] During operation, firstly, the servo motor 35 drives the first worm gear 36 to rotate, the first worm gear 36 drives the first worm wheel 34 to rotate, the first worm wheel 34 drives the rotating shaft 32 and the gear 33 to rotate, the gear 33 drives the rack 31 to rise, and the rack 31 drives the convex block 214 to slide upward inside the convex groove 213, thereby realizing the upward movement of the rotating unit 22 and the smoke detector 4. Then, the micro motor 225 drives the second worm gear 226 to rotate, the second worm gear 226 drives the second worm wheel 224 to rotate, the second worm wheel 224 drives the rotating column 223 to rotate, and the rotating column 223 drives the rotating plate 227 and the smoke detector 4 to rotate, performing multi-range detection.
