Description

Technical Field

[0001] This utility model relates to the technical field of traffic control tools, specifically to a railway signal flagpole structure with an integrated monitoring module. Background Technology

[0002] In railway transportation operations, railway signal flags are an important tool for station assistant duty officers and other staff to transmit instructions during operations such as receiving trains and shunting.

[0003] The railway line experiences extreme temperature differences (e.g., -30℃ in winter to 40℃ in summer in northern regions, with a diurnal temperature range exceeding 30℃). The existing sealant filling the flagpole has a different coefficient of thermal expansion than the flagpole tube and electronic components. Repeated thermal expansion and contraction can lead to stress concentration, causing the sealant to peel off from the component surface or crack, forming new leakage channels. This reduces the protection level of the railway signal flagpole, resulting in short circuits and corrosion of electronic components. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing railway signal flagpoles develop leakage channels during repeated thermal expansion and contraction, leading to short circuits and corrosion of electronic components, and reducing the protection level of the railway signal flagpoles. The purpose is to provide a railway signal flagpole structure with an integrated monitoring module. This structure uses the elastic buffer of high-viscosity adhesive to absorb vibration and temperature stress, and the dense sealing performance of low-viscosity adhesive to prevent moisture intrusion, enabling the module to withstand the environment of thermal cycling and meet the requirements for long-term outdoor operation with large temperature differences.

[0005] This utility model is achieved through the following technical solution:

[0006] A railway signal flagpole structure with an integrated monitoring module includes a flagpole tube, high-viscosity silicone rubber, and low-viscosity silicone rubber. An integrated control motherboard is installed on the inner side of the end of the flagpole tube away from the flag surface, and a battery is connected to the back of the integrated control motherboard. The high-viscosity silicone rubber fills the cavity between the back of the integrated control motherboard and the inner cavity of the flagpole tube. The low-viscosity silicone rubber fills the gap between the integrated control motherboard and the battery and other cavities inside the flagpole tube.

[0007] The beneficial effects of this utility model are as follows: Since the integrated control motherboard is the core computing unit of the module and needs to be kept stable inside the flagpole tube, the motherboard is quickly shaped after being filled with high-viscosity silicone rubber on the back of the motherboard and the tube wall, thus firmly fixing the motherboard to the inside of the tube wall. Because it has high elasticity after curing, it will not make hard contact like a metal bracket, thus avoiding direct collision between the motherboard and the tube wall due to vibration, extending the service life of the module. The gap between the motherboard and the battery and other cavities are sealed with low-viscosity adhesive. In the environment of repeated thermal expansion and contraction, the dense seal of the low-viscosity adhesive prevents moisture intrusion, while the elastic buffer of the high-viscosity adhesive absorbs vibration and temperature stress, enabling the module to withstand the environment of hot and cold cycles, so as to meet the requirements of long-term outdoor operation with large temperature differences.

[0008] In some embodiments, the flagpole tube is further provided with a charging interface, which is electrically connected to the integrated control motherboard. The charging port facilitates charging of the battery inside the flagpole tube.

[0009] In some embodiments, a signal receiving antenna is also included, which is electrically connected to the integrated control motherboard. By electrically connecting the signal receiving antenna to the integrated control motherboard, the core link of the "signal sensing-data processing" closed loop of the railway signal flagpole monitoring module is realized, accurately capturing external railway signals and forming a coordinated response with the integrated control core, thus becoming a reliable node in the railway signal sensing network.

[0010] In some embodiments, an antenna connector is further included, which is plugged into the signal receiving antenna, and the signal receiving antenna is electrically connected to the integrated control motherboard through the antenna connector. By using an antenna connector to electrically connect the signal receiving antenna to the integrated control motherboard, precise impedance matching can be achieved, reducing signal loss.

[0011] In some embodiments, a limiting part is provided on the inner side of the flagpole tube. The limiting part is annular, and the end of the signal receiving antenna away from the antenna connector abuts against the limiting part. By providing the limiting part, the signal receiving antenna is limited.

[0012] In some embodiments, a multi-function tail switch is also included, which is connected to the end of the flagpole tube furthest from the flag surface. Connecting the multi-function tail switch to the end of the flagpole tube furthest from the flag surface facilitates operation.

[0013] In some embodiments, the multi-functional tail switch is provided with an external thread, and the inner side of the flagpole tube is provided with an internal thread that mates with the external thread. The multi-functional tail switch is connected to the flagpole tube by providing the thread for easy replacement and maintenance.

[0014] In some embodiments, a silicone sealing ring is further included. A recessed platform is provided on the flagpole tube, and the silicone sealing ring is mounted on the recessed platform. Both sides of the silicone sealing ring abut against the recessed platform and the tail multi-function switch, respectively. By abutting both sides of the silicone sealing ring against the recessed platform and the tail multi-function switch, the sealing effect on the inner cavity of the flagpole tube is further improved.

[0015] In some embodiments, the multi-functional tail switch integrates a power switch, a power indicator light, and a status indicator light, all of which are electrically connected to the integrated control motherboard. This allows users to power on / off the device by operating the button on the multi-functional tail switch integrated at the bottom, and to understand the device status (such as power-on status, signal connection status) by observing the different colored indicator lights on the tail button. Furthermore, because the entire module is fully internal and sealed, it can operate stably in various harsh weather conditions.

[0016] In some embodiments, the viscosity of the low-viscosity silicone rubber is ≤800 cps, and the viscosity of the high-viscosity silicone rubber is 15000 cps to 20000 cps. By using the above-mentioned viscosities for both the low-viscosity silicone rubber (≤800 cps) and the high-viscosity silicone rubber (15000-20000 cps), the precise matching of fluid characteristics and mechanical properties can specifically address the two core requirements of filling micro-gaps and structural fixation and protection, thereby achieving long-term stable operation of electronic modules in outdoor, vibration, and large diurnal temperature range environments.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. After the cavity between the back of the motherboard and the tube wall is filled with high-viscosity silicone rubber, it is quickly shaped and firmly fixed to the inside of the tube wall. In the environment of repeated thermal expansion and contraction, the dense seal of the low-viscosity rubber prevents moisture intrusion, while the elastic buffer of the high-viscosity rubber absorbs vibration and temperature stress, so that the module can withstand the environment of hot and cold cycles and meet the requirements of long-term outdoor operation with large temperature difference.

[0019] 2. By abutting the two sides of the silicone sealing ring against the sinking platform and the tail multi-functional switch respectively, the sealing effect on the inner cavity of the flagpole tube is further improved. Attached Figure Description

[0031] Example

[0032] like Figures 1-4 As shown, this embodiment provides a railway signal flagpole structure with an integrated monitoring module, including a flagpole tube 2, high-viscosity silicone rubber 10, and low-viscosity silicone rubber 9. An integrated control motherboard 4 is installed on the inner side of the end of the flagpole tube 2 away from the flag surface 8, and a battery 5 is connected to the back of the integrated control motherboard 4. The high-viscosity silicone rubber 10 fills the cavity between the back of the integrated control motherboard 4 and the inner cavity of the flagpole tube 2. The low-viscosity silicone rubber 9 fills the gap between the integrated control motherboard 4 and the battery 5 and other cavities within the flagpole tube 2. After the high-viscosity silicone rubber 10 fills the cavity between the back of the motherboard and the tube wall, it quickly sets and firmly fixes the motherboard to the inner side of the tube wall. In an environment of repeated thermal expansion and contraction, the dense seal of the low-viscosity rubber prevents moisture intrusion, while the elastic buffer of the high-viscosity rubber absorbs vibration and temperature stress, allowing the module to withstand the environment of thermal cycling and meet the requirements for long-term outdoor operation with large temperature differences.

[0033] like Figures 1-3 As shown, the flagpole tube 2 is also equipped with a charging interface 6, which is electrically connected to the integrated control motherboard 4. The charging interface 6 facilitates the charging of the battery 5 inside the flagpole tube 2.

[0034] See Figures 1-4 It also includes a signal receiving antenna 1, which is electrically connected to the integrated control motherboard 4. By electrically connecting the signal receiving antenna 1 to the integrated control motherboard 4, the core link of the "signal perception-data processing" closed loop of the railway signal flagpole monitoring module is realized, accurately capturing external railway signals and forming a coordinated response with the integrated control core, thus becoming a reliable node in the railway signal perception network.

[0035] See Figures 1-4 It also includes an antenna connector 3, which is plugged into the signal receiving antenna 1. The signal receiving antenna 1 is electrically connected to the integrated control motherboard 4 through the antenna connector 3. By setting the antenna connector 3 to electrically connect the signal receiving antenna 1 and the integrated control motherboard 4, precise impedance matching can be achieved, reducing signal loss.

[0036] See Figure 4A limiting part 21 is provided on the inner side of the flagpole tube 2. The limiting part 21 is annular, and the end of the signal receiving antenna 1 away from the antenna connector 3 abuts against the limiting part 21. By providing the limiting part 21, the signal receiving antenna 1 is limited.

[0037] See Figures 1-4 It also includes a multi-functional tail switch 7, which is connected to the end of the flagpole tube 2 away from the flag surface 8. Connecting the multi-functional tail switch 7 to the end of the flagpole tube 2 away from the flag surface 8 facilitates operation.

[0038] See Figure 4 The multi-functional tail switch 7 is provided with an external thread, and the inner side of the flagpole tube 2 is provided with an internal thread that mates with the external thread. The multi-functional tail switch 7 is connected to the flagpole tube 2 by means of threads to facilitate replacement and maintenance.

[0039] See Figure 4 It also includes a silicone sealing ring 11. A recessed platform is provided on the flagpole tube 2, and the silicone sealing ring 11 is installed on the recessed platform. The two sides of the silicone sealing ring 11 abut against the recessed platform and the tail multi-function switch, respectively. By abutting the two sides of the silicone sealing ring 11 against the recessed platform and the tail multi-function switch, the sealing effect on the inner cavity of the flagpole tube 2 is further improved.

[0040] See Figures 1-4 The multi-functional tail switch 7 integrates a power switch, a power indicator light, and a status indicator light, all of which are electrically connected to the integrated control motherboard 4. This allows users to turn the device on and off by operating the button on the multi-functional tail switch 7 integrated at the bottom, and to understand the device status (such as power-on status and signal connection status) by observing the different colored indicator lights on the tail button. Furthermore, because the entire module is completely built-in and sealed, it can operate stably in various harsh weather conditions.

[0041] See Figures 1-4 The low-viscosity silicone rubber 9 has a viscosity of ≤800 cps, and the high-viscosity silicone rubber 10 has a viscosity of 15000 cps to 20000 cps. By using the above-mentioned viscosities for the low-viscosity silicone rubber 9 (≤800 cps) and the high-viscosity silicone rubber 10 (15000-20000 cps), the precise matching of fluid characteristics and mechanical properties is used to specifically address the two core requirements of filling micro-gaps and fixing and protecting the structure, thereby achieving long-term stable operation of electronic modules in outdoor, vibration, and large diurnal temperature range environments.

[0042] Specifically, the end of the flagpole tube 2 away from the multi-functional tail switch 7 is sealed.

[0043] In actual production, the installation drawings of each component are first assembled into the flagpole tube. Then, the cavity between the back of the motherboard and the tube wall is filled with high-viscosity silicone rubber 10 and quickly shaped. The gap between the motherboard and the battery and other cavities are sealed with low-viscosity adhesive 9. At this time, the low-viscosity silicone rubber 9 can also fill the gaps that the high-viscosity silicone rubber 10 does not fill.

[0044] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
