Abstract
Description
Technical Field
[0001] This utility model relates to the field of detectors, and more specifically, to a communication module for a pluggable fault identification fire detector for trains. Background Technology
[0002] High-speed trains have complex structures, carrying a large amount of electrical equipment and cables. The transportation environment is confined and densely populated, making evacuation and rescue difficult. In the event of a fire, failure to detect and handle it promptly can cause serious casualties and economic losses, thus requiring a reliable fire detection and alarm system. With the development of wireless technologies, such as LoRa and ZigBee, wireless communication technologies are increasingly being applied to train fire alarm systems. These technologies offer advantages such as flexible networking, long transmission distances, and strong anti-interference capabilities, solving some problems of traditional wired communication methods and providing technical support for the development of communication modules for pluggable fault-identifying fire detectors on trains.
[0003] A search revealed that Chinese patent CN106251556A discloses a "fire monitoring system," comprising a monitoring backend and multiple fire detectors. The fire detectors include a bus module, a signal amplification module, a control chip, a residual current acquisition unit, and a temperature acquisition unit. The control chip integrates a wireless communication module. The residual current acquisition unit collects the current value of external cables and sends the current signal to the control chip. The temperature acquisition unit collects the temperature of the external environment and sends the temperature signal to the control chip. The control chip obtains the current value based on the current signal and sends the detection signal to the wireless communication modules of other fire detectors via the wireless communication module and the signal amplification module, or sends the detection signal to the monitoring backend via the bus module. The advantage of this invention is the combination of wired and wireless communication connections, reducing wiring in the fire monitoring system. However, it still has the following drawbacks:
[0004] (1) When using the detector, the above application makes it difficult to protect the detector in the event of a fire, which may lead to problems such as electronic component failure and short circuit.
[0005] The aforementioned applications highlight the inherent risk of detectors detaching due to vibrations or bumps during train operation. Therefore, a pluggable fault-identifying fire detector communication module for trains is proposed. Utility Model Content
[0006] The purpose of this invention is to address the current problem that it is difficult to protect detectors during a fire, which can lead to electronic component failure and short circuits.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] The present invention is as follows: a communication module for a train pluggable fault identification fire detector, including a base plate, a support plate fixedly connected to the front side of the base plate, a detector rotatably connected to the bottom of the support plate, a communication module provided on the top of the detector, a wall provided on the back side of the base plate, and a protective device provided on the outside of the detector.
[0009] The protective device includes a motor, the back side of which is fixedly connected to the front side of the wall. The output shaft of the motor is fixedly connected to a bidirectional threaded rod. A threaded sleeve is threadedly connected to the circumferential surface of the bidirectional threaded rod. A push rod is fixedly connected to the circumferential surface of the threaded sleeve. A connecting rod is fixedly connected to the bottom of the push rod. A protective cover is fixedly connected to the side of the connecting rod.
[0010] As a preferred technical solution of this utility model, a limiting rod is fixedly connected to the side of the motor. The circumferential surface of the limiting rod rotates through the inner wall of the threaded sleeve. The function of the limiting rod is to limit the displacement trajectory of the threaded sleeve.
[0011] As a preferred technical solution of this utility model, the number of the threaded sleeve, push rod, connecting rod and protective cover is set to two, and they are symmetrical to each other along the vertical central axis of the detector. The function of the threaded sleeve is to drive the push rod, connecting rod and protective cover to move.
[0012] As a preferred technical solution of this utility model, a reverse locking device is provided on the outside of the base plate. The reverse locking device includes a through groove, which is opened on the front side of the base plate. A bolt is provided inside the through groove, and a nut is threaded to the top of the bolt. A groove is opened on the circumferential surface of the nut.
[0013] As a preferred technical solution of this utility model, a circular plate is fixedly connected to the front side of the base plate, and a rotating rod is fixedly connected to the front side of the circular plate. A pawl is rotatably connected to the circumference of the rotating rod, and the function of the rotating rod is to enable the pawl to rotate.
[0014] As a preferred technical solution of this utility model, the number of the slots is set to several and arranged in a circumferential array along the circumference of the nut. The number of the rotating rod and the pawl is set to two and arranged symmetrically along the vertical central axis of the circular plate. The function of the slots is to allow the pawl to be engaged.
[0015] As a preferred technical solution of this utility model, the number of the through groove, bolt, nut, circular plate, rotating rod and pawl is set to several, in pairs, and symmetrical to each other along the vertical central axis of the base plate. The function of the circular plate is to support the rotating rod and pawl.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. Through the protective device, when the motor is started, the output shaft of the motor rotates, which drives the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it drives the connecting rod to move. When the connecting rod moves, it drives the protective cover to move. Thus, when the protective cover moves, it protects the detector. In the event of a fire, high temperatures are generated. The protective cover can block some of the heat from being transferred to the communication module, preventing the module from failing due to high temperatures, causing electronic component failure, short circuits, and other problems. This ensures that the module can work normally for a certain period of time and continuously transmit fire-related signals.
[0018] 2. The reverse locking device ensures that when the nut is rotated clockwise, the pawl is pushed away by the back of the teeth, preventing the nut from rotating and thus fixing the base plate to the wall. When the nut is rotated counterclockwise, the pawl engages with the slot, preventing the ratchet from reversing. This effectively reduces system failures and false alarms caused by module loosening, ensuring the fire detection system can work reliably at critical moments and providing a guarantee for the safe operation of the train.

[0029] like Figure 1 , Figure 2 , Figure 4 As shown, this embodiment proposes a communication module for a train pluggable fault identification fire detector, including a base plate 1, a support plate 2 fixedly connected to the front side of the base plate 1, a detector 3 rotatably connected to the bottom of the support plate 2, a communication module 4 set on the top of the detector 3, a wall 5 set on the back side of the base plate 1, and a protective device 6 set on the outside of the detector 3.
[0030] The protective device 6 includes a motor 61, the back side of which is fixedly connected to the front side of the wall 5. The output shaft of the motor 61 is fixedly connected to a bidirectional threaded rod 62. A threaded sleeve 63 is threadedly connected to the circumferential surface of the bidirectional threaded rod 62. A push rod 64 is fixedly connected to the circumferential surface of the threaded sleeve 63. A connecting rod 65 is fixedly connected to the bottom of the push rod 64. A protective cover 66 is fixedly connected to the side of the connecting rod 65.
[0031] like Figure 2 , Figure 4 As shown, in a preferred embodiment, based on the above method, a limiting rod 67 is further fixedly connected to the side of the motor 61. The circumferential surface of the limiting rod 67 rotates through the inner wall of the threaded sleeve 63. The function of the limiting rod 67 is to limit the displacement trajectory of the threaded sleeve 63.
[0032] like Figure 2 , Figure 4As shown, in a preferred embodiment, based on the above method, the number of threaded sleeve 63, push rod 64, connecting rod 65 and protective cover 66 is set to two, and they are symmetrical to each other along the vertical central axis of detector 3. The function of threaded sleeve 63 is to drive push rod 64, connecting rod 65 and protective cover 66 to move.
[0033] like Figure 1 , Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, a reverse locking device 7 is further provided on the outside of the base plate 1. The reverse locking device 7 includes a through groove 71, which is opened on the front side of the base plate 1. A bolt 72 is provided inside the through groove 71, and a nut 73 is threadedly connected to the top of the bolt 72. A slot 74 is opened on the circumferential surface of the nut 73.
[0034] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, a circular plate 75 is fixedly connected to the front side of the base plate 1, a rotating rod 76 is fixedly connected to the front side of the circular plate 75, and a pawl 77 is rotatably connected to the circumferential surface of the rotating rod 76. The function of the rotating rod 76 is to enable the pawl 77 to rotate.
[0035] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, the number of slots 74 is set to several and arranged in a circumferential array along the circumference of the nut 73. The number of rotating rods 76 and pawls 77 is set to two and arranged symmetrically along the vertical central axis of the circular plate 75. The function of the slots 74 is to allow the pawls 77 to be engaged.
[0036] like Figure 3 , Figure 5 As shown, in a preferred embodiment, based on the above method, the number of through groove 71, bolt 72, nut 73, circular plate 75, rotating rod 76 and pawl 77 is set to several, in pairs, and symmetrical to each other along the vertical central axis of the base plate 1. The function of the circular plate 75 is to support the rotating rod 76 and pawl 77.
[0037] Specifically, when using this detector protection device: First, when it is necessary to protect the detector 3, the protection device 6 can be used. By starting the motor 61, when the output shaft of the motor 61 rotates, it will drive the bidirectional threaded rod 62 to rotate. When the bidirectional threaded rod 62 rotates, it will drive the two threaded sleeves 63 to move towards the middle. When the two threaded sleeves 63 move towards the middle, they will drive the push rod 64 to move. When the push rod 64 moves, it will drive the connecting rod 65 to move. When the connecting rod 65 moves, it will drive the protective cover 66 to move. Thus, when the protective cover 66 moves, it will protect the detector 3. Furthermore, when a fire occurs, high temperatures will be generated. The protective cover 66 can block some of the heat from being transferred to the communication module, avoiding problems such as electronic component failure and short circuits caused by high temperatures. This ensures that the module can work normally for a certain period of time and continuously transmit fire-related signals.
[0038] When the bolt 72 is installed in the through slot 71, the pawl 77 is pushed open by the back of the teeth when the nut 73 is rotated clockwise, so as not to obstruct the rotation of the nut 73. Thus, the base plate 1 can be fixedly connected to the wall 5. When the train is running, it will generate continuous vibration and impact. In order to prevent the bolt 72 from falling off the wall 5 during the operation of the train, which would cause the detector 3 to be unable to accurately and timely transmit the detected fire information and fault information to the train's central control system, the pawl 77 will lock the slot 74 when the nut 73 is rotated counterclockwise. Through the contact between the slot 74 in the nut 73 and the pawl 77, the nut 73 is prevented from reversing. This can effectively reduce the system failure and false alarm rate caused by module loosening, ensure that the fire detection system can work reliably at critical moments, and provide a guarantee for the safe operation of the train.
[0039] All technical features in this embodiment can be freely combined according to actual needs.
[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
