Detailed Implementation

[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Embodiments of the present invention provide an early warning device for smart stations, such as... Figures 1-6As shown, the early warning device includes a signal transmitter (not shown), a magnetic field generating mechanism 1, a controller (not shown), a drive mechanism 2, and an indicating mechanism 3. The signal transmitter is connected to the smart station and is used to emit a current signal after an accident occurs at the smart station. The duration of the current signal corresponds to the accident level of the smart station; the higher the accident level, the longer the duration of the current signal. The magnetic field generating mechanism 1 is used to generate a magnetic field. The controller is communicatively connected to the signal transmitter and the magnetic field generating mechanism 1, and is used to receive the current signal and control the magnetic field generating mechanism 1 to generate the magnetic field. The strength of the magnetic field corresponds to the duration of the current signal; that is, the longer the duration of the current signal, the stronger the magnetic field. The driving mechanism 2 includes a first moving rod 201 and a moving plate 202 movably inserted into the tube 101 of the magnetic field generating mechanism 1. The moving plate 202 is vertically arranged and fixed to the first moving rod 201. The warning device includes a housing 4, and a stepped cavity is formed inside the housing 4. The stepped cavity includes a first cavity 402 and a second cavity 403. The tube 101 is fixed by a support base and the bottom wall of the second cavity 403. The magnetic field generating mechanism 1 also includes an electromagnetic coil. 102, baffle 103, fixing plate 104, connecting plate 105, fourth spring 106, and second moving rod 107. An electromagnetic coil 102 is wound around the outside of the tube body 101. The warning device also includes a power supply that is communicatively connected to the controller. The electromagnetic coil 102 is electrically connected to the power supply. The baffle 103 is fixed to one end of the tube body 101. The first moving rod 201 passes through the baffle 103 and the tube body 101. The second moving rod 107 is arranged parallel to and spaced apart from the first moving rod 201. The two ends of the connecting plate 105 are respectively connected to the first moving rod 201 and the second moving rod 107. 202 is located on the lower side of the second moving rod 107, the fixing plate 104 is located at the end of the first moving rod 201 away from the connecting plate 105, the fourth spring 106 is sleeved on the first moving rod 201 and located between the tube body 101 and the fixing plate 104, and a sliding sleeve is radially extended on one side of the baffle 103. A through hole is formed on the sliding sleeve for the second moving rod 107 to pass through. The distance that the first moving rod 201 moves along the axial direction of the tube body 101 corresponds to the strength of the magnetic field. That is, the stronger the magnetic field, the longer the distance that the first moving rod 201 moves along the axial direction of the tube body 101.The indicating mechanism 3 includes multiple warning modules 301 positioned below the movable plate 202 and spaced apart along the moving direction of the movable plate 202. Each warning module 301, triggered by the movable plate 202, emits a warning signal corresponding to the accident level. The movable plate 202 has multiple preset positions along its moving direction, each corresponding to a distance the first movable rod 201 moves axially along the pipe body 101. Each time the movable plate 202 moves to a preset position, it triggers a corresponding warning module 301, which then emits a specific warning signal. This warning signal corresponds to the accident level of the smart station. Furthermore, the longer the first movable rod 201 moves axially along the pipe body 101, the higher the warning level of the warning signal emitted by the warning module 301. This warning device has a stable structure, fast response time, reliable signal transmission, and wide applicability. It can easily and clearly classify the accident levels occurring in the smart station, thereby providing targeted warnings to the staff of the smart station.

[0032] In this embodiment, after the power supply to the electromagnetic coil 102 is stopped, the first moving rod 201 is reset under the action of the fourth spring 106, thereby realizing the reset of the moving plate 202.

[0033] In one embodiment of the present invention, the warning module 301 includes a guide component 302, a transmission component 303, a drive component 304, and an auditory component 305. The guide component 302 is disposed below the moving plate 202 and is used to move vertically downward when triggered by the moving plate 202. The transmission component 303 includes a first transmission wheel 3031 connected to the guide component 302 and a second transmission wheel 3032 for transmission connection with the first transmission wheel 3031. The drive component 304 is disposed at intervals below the first transmission wheel 3031 and is used to provide driving force to the first transmission wheel 3031. The auditory component 305 includes a rigid protrusion 3051 disposed on the second transmission wheel 3032 and a rigid spring 3052 for emitting a warning sound when triggered by the rigid protrusion 3051. Specifically, the drive assembly 304 includes a drive motor 3041 communicatively connected to the controller and a drive roller 3042 connected to the drive end of the drive motor 3041. The drive roller 3042 is spaced below the first transmission wheel 3031 and is used to drive the first transmission wheel 3031. When the moving plate 202 does not trigger the guide assembly 302, there is a gap between the drive roller 3042 and the first transmission wheel 3031, and the drive roller 3042 cannot provide driving force to the first transmission wheel 3031. When the moving plate 202 triggers the guide assembly 302, the guide assembly 302 moves vertically downward, thereby moving the first transmission wheel 3031 downward, so that the first transmission wheel 3031 moves downward. The driving wheel 3031 meshes with both the driving roller 3042 and the second transmission wheel 3032. The driving roller 3042 then provides driving force to the first transmission wheel 3031, which in turn drives the second transmission wheel 3032 to rotate. The second transmission wheel 3032 has multiple rigid protrusions 3051 evenly distributed circumferentially on its side surface. The auditory component 305 also includes a mounting base 3053 on one side of the second transmission component. A rigid spring 3052 is located on the side surface of the mounting base 3053 facing the rigid protrusions 3051. After the second transmission wheel 3032 rotates, the multiple rigid protrusions 3051 on it collide sequentially with the rigid spring 3052, emitting a warning sound upon collision. Furthermore, the number of rigid protrusions 3051 in the auditory components 305 of each warning module 301 varies. The more rigid protrusions 3051 there are, the more frequent the warning sounds emitted by the auditory component 305, indicating a higher accident level.

[0034] In one embodiment of the present invention, a plurality of circular holes 404 are provided on the side wall of the housing 4 near the hearing component 305. The diameter of the circular holes 404 is in the range of 3mm-5mm. The arrangement of the circular holes 404 is conducive to the outward transmission of the warning sound.

[0035] In one embodiment of the present invention, the warning device further includes a housing 4 and a support plate 5 with one end fixed to the inner wall of the housing 4. The lower end of the movable plate 202 has a first inclined portion formed on the side facing the magnetic field generating mechanism 1. The guide assembly 302 includes a contact block 3021, a first guide post 3022, a first spring 3023 and a connecting rod 3024. The contact block 3021 is disposed below the movable plate 202 and has a second inclined portion 3025 for cooperating with the first inclined portion. The first guide post 3022 is disposed below the contact block 3021 and passes through the support plate 5. The first spring 3023 is sleeved on the first guide post 3022 and is located between the contact block 3021 and the support plate 5. The upper end of the connecting rod 3024 is connected to the first guide post 3022, and the first transmission wheel 3031 is connected to the lower end of the connecting rod 3024. Specifically, the connecting rod 3024 is L-shaped. When the guide assembly 302 is triggered, the first inclined part and the second inclined part 3025 contact each other and gradually apply downward pressure to the contact block 3021 through the second inclined part 3025. The contact block 3021 compresses the first spring 3023. After the first spring 3023 is compressed, the contact block 3021, the first guide post 3022 and the connecting rod 3024 move downward as a whole. The first transmission wheel 3031 connected to the connecting rod 3024 moves downward accordingly, thereby realizing the meshing of the first transmission wheel 3031 with the drive roller 3042 and the second transmission wheel 3032.

[0036] In one embodiment of the present invention, the transmission assembly 303 further includes a connecting shaft 3033 fixed to the lower end of the connecting rod 3024. The first transmission wheel 3031 is rotatably mounted on the connecting rod 3024. The circumferential wall of the first transmission wheel 3031 is provided with a plurality of strip-shaped protrusions 3034 (the strip-shaped protrusions 3034 are made of rubber) distributed circumferentially. The setting direction of the strip-shaped protrusions 3034 is consistent with the axial direction of the first transmission wheel 3031. The drive assembly 304 and the second transmission wheel 3032 are respectively provided with a first strip-shaped groove 3043 and a second strip-shaped groove 3035 for cooperating with the strip-shaped protrusions 3034. Specifically, the first strip groove 3043 is disposed on the drive roller 3042. Through the cooperation between the strip protrusion 3034 and the first strip groove 3043 and the second strip groove 3035 respectively, the power transmission between the drive roller 3042, the first transmission wheel 3031 and the second transmission wheel 3032 is realized. In addition, the first transmission wheel 3031 will not drive the connecting shaft 3033 to rotate when it rotates.

[0037] In one embodiment of the present invention, the guide assembly 302 further includes a first push block 3026 disposed at the lower end of the first guide post 3022. The first push block 3026 is provided with a third inclined portion. The warning device further includes a clamping member 6 disposed at intervals below the support plate 5 and a second spring 7 for pushing the clamping member 6 to move in the horizontal direction. The clamping member 6 includes a movable plate portion 601 abutting against one end of the second spring 7 and a plurality of clamping portions 602. The plurality of clamping portions 602 are all located above the movable plate portion 601 and are distributed at intervals along the axial direction of the movable plate portion 601. The clamping portion 602 is provided with a first inclined section 6021 for cooperating with the third inclined portion and a slot section 6022 for restricting the vertical movement of the first push block 3026. Specifically, the housing 4 is also provided with a first vertical plate 10 and a second vertical plate 11 at intervals. The first vertical plate 10 and the second vertical plate 11 are both fixed on the bottom wall of the first cavity 402. The clamping member 6 also includes a first columnar part and a second columnar part respectively provided at both ends of the movable plate part 601. The first columnar part passes through the first vertical plate 10, and the second columnar part passes through the second vertical plate 11. The second spring 7 is sleeved on the first columnar part. One end of the second spring 7 abuts against the first vertical plate 10 and the second spring 7 abuts against the movable plate part 601. The slot section 6022 is provided with a slot with an opening facing away from the second spring 7. When the contact block 3021, the first guide post 3022, and the connecting rod 3024 move downward as a whole, the first push block 3026 also moves downward. The third inclined part contacts the first inclined section 6021 and gradually applies a pushing force to the clamping member 6 through the first inclined section 6021. The clamping member 6 compresses the second spring 7. After the second spring 7 is compressed, the clamping member 6 moves in the direction of the second spring 7. The downward movement of the first push block 3026 and the lateral movement of the clamping member 6 occur simultaneously. After the first push block 3026 moves down into the slot, it stops, and the lateral movement of the clamping member 6 also stops.

[0038] In one embodiment of the present invention, the warning module 301 includes a visual component 8 for issuing visual warnings. The visual component 8 and the auditory component 305 cooperate to provide staff with visual and auditory warnings simultaneously, which is intuitive and accurate and improves warning efficiency.

[0039] In one embodiment of the present invention, the vision component 8 includes a rotating shaft 801 fixed inside the housing 4 and a coil spring 802 wound around the rotating shaft 801. One end of the coil spring 802 is fixed to the rotating shaft 801, and the other end of the coil spring 802 is fixed to the first push block 3026. A warning coating (not shown in the figure) is applied to the coil spring 802, and a viewing window 401 for observing the warning coating is provided on the housing 4. Specifically, the vision component 8 also includes a rotating shaft 801 mounting base 3053 for mounting the rotating shaft 801, which is disposed on the inner wall of the housing 4. In this embodiment, the warning coating refers to a colored coating. When the contact block 3021, the first guide post 3022, the connecting rod 3024, and the first push block 3026 move downward as a whole, the coil spring 802 is stretched and unfolded. The staff can observe the warning coating on the coil spring 802 through the viewing window 401 and thus receive a visual warning. Furthermore, the colors of the warning coatings on the coil springs 802 in the vision components 8 of each warning module 301 are different. The darker the color of the warning coating, the higher the accident level.

[0040] In one embodiment of the invention, the warning device further includes a reset component 9 for resetting the guide component 302 in order to deactivate the visual and auditory warnings.

[0041] In one embodiment of the present invention, the reset assembly 9 includes a stop block 901, a third spring 902, a second guide post 903 that penetrates the support plate 5 and can move up and down, and a second push block 904 disposed below the second guide post 903. The stop block 901 is disposed at the upper end of the second guide post 903. The third spring 902 is sleeved on the second guide post 903 and located between the stop block 901 and the support plate 5. The second push block 904 is provided with a fourth inclined portion. The clamping member 6 is also provided with a reset portion 603. The reset portion 603 is located above the movable plate portion 601 and near the end of the second spring 7. The reset portion 603 is provided with a second inclined section for cooperating with the fourth inclined portion. The inclined length of the second inclined section is greater than the inclined length of the first inclined section 6021. Specifically, when the stop block 901 is subjected to a downward force, the stop block 901 compresses the third spring 902. After the third spring 902 is compressed, the stop block 901, the second guide post 903, and the second push block 904 move downward as a whole. The fourth inclined part and the second inclined section contact each other and gradually apply a pushing force to the clamping member 6 through the second inclined section. The clamping member 6 compresses the second spring 7. After the second spring 7 is compressed, the clamping member 6 moves in the direction of the second spring 7 until the second push block 904 moves downward to the top of the movable plate part 601. Since the inclined length of the second inclined section is greater than the inclined length of the first inclined section 6021, when the second push block 904 stops moving downward, the first push block 3026 has exited the slot. The guide assembly 302 is reset under the action of the first spring 3023, and the visual warning and auditory warning are deactivated.

[0042] In one embodiment of the present invention, the stop block 901 is made of a magnet, and the reset assembly 9 further includes an electromagnet 905 spaced below the second push block 904, the electromagnet 905 being communicatively connected to the controller. Specifically, the warning device also includes a warning release button electrically connected to the controller, and the electromagnet 905 being electrically connected to a power source. When the operator presses the warning release button, the button sends a control command to the controller, which then controls the power source to supply power to the electromagnet 905. A magnetic force is generated between the electromagnet and the stop block 901, and the stop block 901 compresses the third spring 902 downward under the action of this magnetic force, thereby resetting the guide assembly 302 and deactivating both the visual and auditory warnings. This makes the warning device easy to operate.
