[0003] The existing technology also includes monitoring and alarm functions, which requires testing the sensitivity of the lock body. High temperatures and dust can easily damage the internal circuitry of the lock body, thereby impairing its sensitivity. The existing technology lacks good heat dissipation and dust protection for the lock body. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic detection safety electronic control device for locomotive door and window locking to solve the problems mentioned in the background technology. This utility model has a novel structure. It protects the lock body itself from heat dissipation and dust through protective components and protective covers. Through the internal structure of the protective components, the filter plate and drying plate can be cleaned and replaced each time the protective cover is opened for use, so as to maintain efficient dust prevention and dehumidification and protect the sensitivity of the lock body.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic detection safety electronic control device for locomotive door and window locking, comprising a lock body, wherein a non-contact high-voltage sensor and a locomotive high-voltage transformer are installed inside the lock body, a mounting plate is fixed to one end of the lock body, and protective covers are rotatably mounted on both sides of the top of the lock body via a rotating shaft, the two protective covers being combined to cover the top of the lock body, a protective component is provided at one end of the lock body, the protective component including an air inlet box, the air inlet box being fixed to the end of the lock body away from the mounting plate, and air vents being provided on both sides of the air inlet box, a cooling fan is fixedly mounted on one side of the lock body corresponding to the rear air vent of the air inlet box, a ring-shaped belt is provided inside the air inlet box, and a drying sheet is attached to the outer surface of the belt, and filter plates are rotatably mounted on the bottom of the air vent and both sides of the belt via hinges and torsion springs.

[0006] Furthermore, a keyhole is provided on the top surface of the lock body, and a knob is provided on the surface of the lock body located on the side of the keyhole. A playback window is provided at the upper end of the knob and the keyhole, and an indicator light is provided on one side of the playback window. An alarm light is provided on one side of the knob.

[0007] Furthermore, a magnetic suction plate is fixed at the middle position on one side of each of the two protective covers, and the two magnetic suction plates are magnetically attracted to each other.

[0008] Furthermore, the protective assembly also includes wind deflectors. The air inlet box has two wind deflectors located on both sides of the belt. The top of the air inlet box is sealed with a top cover, and the wind deflectors are fixedly connected to the top cover. The top and bottom of the belt are provided with connecting shafts, and the connecting shafts are rotatably installed at the bottom of the top cover.

[0009] Furthermore, the belt is fixed with protruding posts at equal intervals on its side, the filter plate is fixed with an extension plate on the side facing the belt, and the extension plate is alternately pressed and contacted by the protruding posts, and the bottom of the air inlet box is sealed with a bottom cover.

[0010] Furthermore, a gear is fixed to one end of the connecting shaft that protrudes from the top cover, and a toothed plate is meshed with one side of the gear. A limiting frame is provided on the outer surface of the top cover corresponding to the position of the toothed plate, and the toothed plate is slidably inserted into the limiting frame.

[0011] Furthermore, an electric push rod is fixed to one side of the top cover located on the limiting frame, and the extended end of the electric push rod is fixedly connected to the limiting frame.

[0012] Furthermore, one end of the rotating shaft of the protective cover is provided with a groove, and a pull rope is connected inside the groove through a slider and a spring. The other end of the pull rope is fixedly connected to the bottom of the toothed plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. When the protective shell is opened, the pull rope is pulled a certain distance due to the rotation of the rotating shaft, causing the toothed plate to move downward along the limiting frame. Before this, the electric push rod pushes the limiting frame to move horizontally, bringing the toothed plate into contact with the gear. As the toothed plate moves and meshes with the gear, it drives the gear to rotate, and then the belt rotates to replace the part exposed at the bottom of the baffle plate over a certain distance, keeping the exposed drying sheet sufficiently dry. As the belt moves, the protrusion contacts the extension plate during the movement, thereby driving the filter plate to rotate. During the rotation, the dust is thrown to the lower end of the air inlet box by shaking. It can be cleaned by opening the bottom cover, or the drying sheet on the belt can be replaced by opening the top cover.

[0015] 2. This utility model uses a torsion spring to install the protective cover and the mounting plate. When opened, it can automatically spring open, and when closed, it is attracted together by two magnetic plates, protecting the components on the lock body from damage by external forces.

[0016] 3. In the process of the protective cover rotating and covering, a spring is connected between the toothed plate and the limiting frame, which allows the toothed plate to automatically return to its original position. The electric push rod drives the limiting frame and the toothed plate away from the gear, and the toothed plate moves upward. During this process, the gear will not rotate. The pull rope keeps the toothed plate and the limiting frame moving synchronously through the slide groove.

[0017] 4. Compared with the prior art, this utility model, through the internal structure of the protective component, allows for the cleaning and replacement of the filter plate and drying sheet each time the protective cover is opened for use, maintaining efficient dust prevention, heat dissipation, and dehumidification, and protecting the sensitivity of the lock body.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: an automatic detection safety electronic control device for locomotive door and window locking, comprising a lock body 1, characterized in that: a non-contact high-voltage sensor and a locomotive high-voltage transformer are installed inside the lock body 1; a mounting plate 11 is fixed to one end of the lock body 1, and protective covers 2 are rotatably mounted on both sides of the top of the lock body 1 via a rotating shaft; the two protective covers 2 are combined to cover the top of the lock body 1; a protective component 3 is provided at one end of the lock body 1; the protective component 3 includes an air inlet box 31, which is fixed to the end of the lock body 1 away from the mounting plate 11, and air vents 32 are provided on both sides of the air inlet box 31; a cooling fan vent 17 is fixedly installed on one side of the lock body 1 corresponding to the rear air vent 32 of the air inlet box 31; the air inlet box 31... An annular belt 36 is installed inside, and a drying sheet is attached to the outer surface of the belt 36. The air inlet box 31 is located at the bottom of the air window 32 and on both sides of the belt 36. Filter plates 37 are rotatably installed via hinges and torsion springs. When using the device, the protective cover 2 and the protective assembly 3 are installed on the outside of the lock body 1. The outlet end of the air inlet box 31 is connected to the cooling fan 17. The protective assembly 3 protects the lock body 1 from dust, heat dissipation, and drying of the gas. The protective shell protects the lock body 1 from impact. Each time the protective cover 2 is opened, the filter plates 37 and the drying box inside the air inlet box 31 are automatically cleaned and replaced to maintain their dust removal and drying performance. Air flows out from the rear air window 32 through the front air window 32 along the U-shaped bend inside the air inlet box 31, passing through the dust removal and drying area.

[0027] In this embodiment, a lock hole 13 is provided on the top surface of the lock body 1, and a knob 14 is provided on the surface of the lock body 1 on one side of the lock hole 13. A playback window 12 is provided at the upper end of the knob 14 and the lock hole 13, and an indicator light 15 is provided on one side of the playback window 12. An alarm light 16 is provided on one side of the knob 14. The components and functions on the lock body 1 are those of an existing smart electric lock. The principle is as follows: when the locomotive sunroof is closed after the roof work is completed, the electric lock of the device will lock the sunroof. The electric lock has a feedback function. At this time, if the knob 14 on the electric lock is turned, the electric lock cannot be opened and the locomotive sunroof cannot be opened. After the locomotive sunroof is closed, the electric lock is in a deadbolt state and the locomotive sunroof cannot be opened. When the overhead contact line on the locomotive is energized, if an unlocking operation is performed by pressing knob 14 on the control box, the electric lock will not activate, and the locomotive sunroof will remain closed. Each press of knob 14 will trigger a two-part voice alarm from the control box's horn, warning "Danger: Electricity - Do Not Approach." Simultaneously, the "Electrical" indicator light 15 on the control box will flash. If the locomotive sunroof is not closed or not properly closed, and the locomotive moves from a de-energized area to an energized area with energized overhead contact line, the horn in the control box will automatically and continuously issue a "Danger: Electricity - Do Not Approach" voice alarm to alert workers until the sunroof is properly closed and locked, at which point the alarm will stop. When the locomotive enters a disconnector section with de-energized overhead contact line, or when the locomotive is in a depot without overhead contact line, pressing knob 14 on the control box will immediately and quickly unlock the electric lock, allowing the sunroof to be opened for rooftop work. The device will not function properly when powered off. In this case, the key can be inserted into the electric lock 13 and rotated counterclockwise one turn, then the knob 14 on the electric lock can be turned to open the locomotive sunroof for roof work; when the high voltage status detected by the high voltage sensor is inconsistent with the high voltage status detected by the high voltage transformer, the device will display an indicator light to indicate that the sensor that did not detect a high voltage signal is abnormal, reminding the operator to check the high voltage sensor or voltage transformer; when the device's high voltage sensor detects a high voltage signal but the high voltage transformer does not detect a high voltage signal, the device will display an indicator light to indicate that the high voltage transformer is abnormal, and a communication interface is reserved to transmit the abnormal status of the high voltage transformer to other human-machine interaction devices such as the CTU host for alarm prompts.

[0028] In this embodiment, a magnetic suction plate 21 is fixed at the middle position of one of the two adjacent protective covers 2. The two magnetic suction plates 21 are magnetically attracted to each other. The protective cover 2 and the mounting plate 11 are installed by a torsion spring. When opened, it can automatically pop open. When closed, it is attracted together by the two magnetic suction plates 21 to protect the components on the lock body 1 and prevent them from being damaged by external forces.

[0029] In this embodiment, the protective component 3 further includes wind baffles 33. Two wind baffles 33 are located inside the air inlet box 31 on both sides of the belt 36. A top cover 39 is sealed and installed on the top of the air inlet box 31, and the wind baffles 33 are fixedly connected to the top cover 39. Connecting shafts 35 are provided at the top and bottom of the belt 36, and the connecting shafts 35 are rotatably mounted on the bottom of the top cover 39. Protrusions 314 are fixedly fixed at equal intervals on the side of the belt 36. An extension plate 315 is fixed to the side of the filter plate 37 facing the belt 36, and the extension plate 315 alternately contacts the protrusions 314. A bottom cover is sealed and installed at the bottom of the air inlet box 31. 34. A gear 38 is fixed to one end of the connecting shaft 35 that protrudes from the top cover 39. A toothed plate 310 is meshed with one side of the gear 38. A limiting frame 312 is provided on the outer surface of the top cover 39 corresponding to the position of the toothed plate 310, and the toothed plate 310 is slidably inserted into the limiting frame 312. An electric push rod 313 is fixed to one side of the top cover 39 located at the limiting frame 312, and the extended end of the electric push rod 313 is fixedly connected to the limiting frame 312. A sliding groove 316 is provided at one end of the rotating shaft of the protective cover 2, and a pull rope 311 is connected inside the sliding groove 316 through a slider and a spring. The other end of the pull rope 311 is connected to the toothed plate. The bottom of 310 is fixedly connected. When the protective shell is opened, the pull rope 311 is pulled a certain distance due to the rotation of the rotating shaft, causing the toothed plate 310 to move downward along the limiting frame 312. Before this, the electric push rod 313 pushes the limiting frame 312 to move horizontally, bringing the toothed plate 310 into contact with the gear 38. As the toothed plate 310 moves and meshes with the gear 38, it drives the gear 38 to rotate. In turn, the belt 36 rotates to replace the exposed part at the bottom of the baffle plate 33 over a certain distance, ensuring that the exposed drying sheet has sufficient dryness. As the belt 36 moves, the protrusion 314 contacts the extension plate 315 during the movement, thereby... The filter plate 37 is rotated, and during the rotation, the dust is shaken and thrown to the lower end of the air inlet box 31. It can be cleaned by opening the bottom cover 34, or the drying sheet on the belt 36 can be replaced by opening the top cover. During the rotation of the protective cover 2, a spring is connected between the toothed plate 310 and the limiting frame 312, which allows the toothed plate 310 to automatically return to its original position. The electric push rod 313 drives the limiting frame 312 and the toothed plate 310 away from the gear 38, and the toothed plate 310 moves upward. During this process, the gear 38 does not rotate. The pull rope 311 moves synchronously with the toothed plate 310 and the limiting frame 312 through the slide groove 316.

[0030] When using the device, the protective cover 2 and protective assembly 3 are installed on the outside of the lock body 1. The outlet end of the air inlet box 31 is connected to the cooling fan duct 17. The protective assembly 3 protects the lock body 1 from dust, heat dissipation, and drying gases, while the protective shell protects the lock body 1 from impact. Each time the protective cover 2 is opened, the filter plate 37 and drying box inside the air inlet box 31 are automatically cleaned and replaced to maintain their dust removal and drying performance. When the protective shell is opened, the pull rope 311 is pulled a certain distance due to the rotation of the rotating shaft, causing the toothed plate 310 to move downward along the limit frame 312. Before this, the electric push rod 313 pushes the limit frame 312 to move horizontally, bringing the toothed plate 310 into contact with the gear 38. As the toothed plate 310 moves and meshes with the gear 38, it drives the gear 38 to rotate, which in turn causes the belt 36 to rotate and replace the exposed part at the bottom of the baffle plate 33 a certain distance, keeping the exposed drying sheet intact. With sufficient drying properties, as the belt 36 moves, the protrusion 314 contacts the extension plate 315 during movement, thereby driving the filter plate 37 to rotate. During rotation, dust is thrown to the lower end of the air inlet box 31 by shaking. It can be cleaned by opening the bottom cover 34, or the drying sheet on the belt 36 can be replaced by opening the top cover. During the rotation of the protective cover 2, a spring connects the toothed plate 310 and the limiting frame 312, which allows the toothed plate 310 to automatically return to its original position. The electric push rod 313 drives the limiting frame 312 and the toothed plate 310 away from the gear 38, and the toothed plate 310 moves upward. During this process, the gear 38 does not rotate. The pull rope 311 moves synchronously with the toothed plate 310 and the limiting frame 312 through the slide groove 316. Air flows out from the rear air window 32 through the front air window 32 along the U-shaped bend in the air inlet box 31, passing through the dust removal and drying area.
