Description

Technical Field

[0001] This utility model relates to the field of sealing and waterproofing equipment technology, specifically to a smart light pole multi-functional communication gateway terminal device. Background Technology

[0002] In the application scenarios of smart light poles, the multi-functional communication gateway terminal equipment of smart light poles is usually installed in the outdoor environment and is subject to the long-term impact of natural factors such as rain and humidity.

[0003] Currently, the sealing structure of existing equipment casings is often inadequate, with gaps easily appearing at the joints, allowing rainwater and moisture to seep in, affecting the normal operation of electronic components and even causing equipment malfunctions. Moreover, most equipment lacks effective water immersion detection and response mechanisms, failing to issue timely warning signals when water immersion occurs, making it difficult for maintenance personnel to quickly detect and handle problems. The sealing performance at equipment interfaces is insufficient, easily reducing communication stability due to moisture intrusion. Furthermore, the casing struggles to balance heat insulation and waterproofing performance under different climatic conditions, further shortening the equipment's lifespan and failing to meet the requirements for long-term stable operation of smart light poles. Therefore, there is room for improvement. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a smart light pole multi-functional communication gateway terminal device.

[0005] The smart light pole multi-functional communication gateway terminal device provided in this application adopts the following technical solution:

[0006] A smart light pole multi-functional communication gateway terminal device includes a gateway housing, which comprises an inner shell and an outer shell, forming a vacuum insulation cavity filled with aerogel. A stepped sealing structure is provided at the joints of the gateway housing, comprising mutually adaptable bosses and grooves. An annular sealing groove is formed on the surface of the boss, and a water-swellable rubber ring is embedded in the annular sealing groove. A compression ring corresponding to the annular sealing groove is fixed to the inner wall of the groove. A drain hole is provided at the bottom of the gateway housing, and a one-way drain valve is installed in the drain hole. A water immersion sensor and a status indicator light are installed on the outer wall of the gateway housing. The water immersion sensor and the status indicator light are electrically connected to a water immersion fault circuit. The water immersion sensor is used to monitor the humidity inside the gateway housing in real time. If an abnormal humidity is detected, the status indicator light is triggered to illuminate, and the current status of the device is displayed intuitively through a flashing mode.

[0007] By adopting the above technical solution, the gateway housing uses an inner shell and an outer shell to form a vacuum insulation cavity filled with aerogel. This effectively blocks the influence of external temperature on internal components, improving the stability of the equipment under different temperature environments. The stepped sealing structure, combined with a water-swellable rubber ring with an expansion ratio of 150%-300%, forms multiple seals at the joints. When exposed to water, the rubber ring expands within a 5-10mm gap to achieve a complete seal, significantly improving the waterproof performance of the gateway housing. The bottom drain hole and one-way drain valve can promptly drain any small amount of water that seeps into the housing, preventing damage to internal components. The water immersion sensor works in conjunction with the water immersion fault circuit. The detection unit converts humidity parameters into voltage signals through a voltage divider circuit composed of a humidity-sensitive resistor, etc. After processing, amplification, and threshold comparison by the processing unit, the execution unit controls the status indicator light to output the corresponding status signal. This allows for real-time monitoring of whether the equipment is submerged in water and timely warnings, facilitating quick problem detection and handling by maintenance personnel. The overall structural design takes into account heat insulation, waterproofing, drainage, and water immersion detection functions, significantly improving the reliability and service life of the smart light pole communication gateway terminal equipment in complex outdoor environments and ensuring stable operation of the equipment.

[0008] Optionally, the expansion ratio of the water-swellable rubber ring is 150%-300%, which ensures a complete seal within a 5-10mm gap.

[0009] By adopting the above technical solution, the water-swellable rubber ring, with an expansion ratio of 150%-300%, can form a reliable sealing barrier when a 5-10mm gap appears at the splicing point of the gateway housing. This barrier is formed by the full expansion of the rubber ring after contact with water, allowing it to fully expand and tightly fit with the compression ring. This effectively prevents water from seeping into the interior of the gateway housing, ensuring the waterproof sealing performance of the equipment even in the presence of assembly gaps or slight deformation. It also provides a stable protective environment for internal components and reduces the risk of equipment failure due to water ingress.

[0010] Optionally, each interface of the gateway housing is equipped with a waterproof connector, which is made of high-density rubber material and has good sealing performance and corrosion resistance.

[0011] By adopting the above technical solution, the waterproof connector at the gateway housing interface is made of high-density rubber material. With its good sealing performance, it effectively prevents water from entering the device from the interface gaps, avoiding short circuits and component damage caused by water ingress. Its corrosion resistance can resist the erosion of corrosive substances such as acids and alkalis in the outdoor environment, extending the service life of the interface and ensuring that the device interface maintains stable connection and protection performance during long-term use.

[0012] Optionally, the top of the gateway housing is provided with an arc-shaped flow guide plate, and the surface of the arc-shaped flow guide plate is coated with a hydrophobic coating.

[0013] By adopting the above technical solution, the arc-shaped guide plate on the top of the gateway housing can guide rainwater with its arc structure, allowing rainwater to flow down quickly along the arc surface and reducing the residence time of rainwater on the top of the housing. The hydrophobic coating on the surface further reduces the adhesion between rainwater and the surface of the guide plate, accelerating the sliding of rainwater. The combination of the two effectively reduces the possibility of rainwater penetrating into the joints or interfaces of the housing, enhances the rainproof capability of the equipment, and provides additional protection for the internal components of the gateway housing.

[0014] Optionally, the water immersion fault circuit includes a detection unit, a processing unit, and an execution unit. The detection unit is connected to a water immersion sensor to acquire humidity parameters and output a detection signal. The processing unit is coupled to the detection unit to receive the detection signal and output a processing signal. The execution unit is coupled to the processing unit and a status indicator light and is used to control the status indicator light to output a corresponding status signal according to the processing signal, so that the status indicator light outputs a flashing signal corresponding to the degree of water immersion.

[0015] By adopting the above technical solution, the detection unit, processing unit and execution unit in the water immersion fault circuit work together to convert the humidity parameters obtained by the water immersion sensor into a processable detection signal. After analysis and processing by the processing unit, a corresponding processing signal is formed. Then, the execution unit drives the status indicator to output a flashing signal that matches the degree of water immersion. This enables real-time monitoring and accurate feedback of the equipment's water immersion status, ensuring that when water immersion occurs, it can be promptly transmitted to maintenance personnel through an intuitive flashing signal, facilitating quick detection and handling of the problem.

[0016] Optionally, the detection unit includes a humidity-sensitive resistor RS and a resistor R3. The humidity-sensitive resistor RS and the resistor R3 form a voltage divider circuit to output a voltage signal corresponding to the humidity. The humidity-sensitive resistor RS is arranged on the outside of the gateway housing. The output terminal of the voltage divider circuit is electrically connected to the non-inverting input terminal of the operational amplifier N1 in the processing unit, converting the humidity signal into a voltage signal and transmitting it to the processing unit.

[0017] By adopting the above technical solution, the voltage divider circuit composed of the humidity-sensitive resistor RS and resistor R3 in the detection unit can convert the humidity change on the outside of the gateway housing into a corresponding voltage signal. The humidity-sensitive resistor RS is arranged on the outside of the housing to directly sense the external humidity, ensuring the timeliness and accuracy of the detection. The converted voltage signal is transmitted to the non-inverting input of the operational amplifier N1 in the processing unit, which can realize the stable conversion and transmission of humidity signal to electrical signal. This provides a reliable signal basis for the subsequent processing unit to analyze and process the humidity information, enabling the water immersion fault circuit to accurately monitor humidity changes and providing effective data support for the water immersion protection and status indication of the equipment.

[0018] Optionally, the processing unit includes an operational amplifier N1 and a threshold adjustment module. The threshold adjustment module includes resistors R1 and R2. Resistors R1 and R2 form a voltage divider circuit to provide a threshold voltage to the inverting input terminal of the operational amplifier N1. The non-inverting input terminal of the operational amplifier N1 is coupled to the signal output terminal of the detection unit, and the inverting input terminal is connected to the output terminal of the threshold adjustment module.

[0019] By adopting the above technical solution, the operational amplifier N1 in the processing unit works in conjunction with the threshold adjustment module composed of resistors R1 and R2. The voltage divider circuit formed by the threshold adjustment module provides a stable threshold voltage to the inverting input terminal of the operational amplifier, while the non-inverting input terminal of the operational amplifier receives the humidity voltage signal from the detection unit. By comparing the two, it is possible to accurately determine whether the current humidity exceeds the preset threshold, thereby achieving effective processing and identification of the humidity signal. This provides an accurate signal basis for the subsequent execution unit to control the status indicator light according to the processing result, ensuring that the water immersion fault circuit can respond to different humidity conditions in a timely manner.

[0020] Optionally, the execution unit includes a transistor Q1, a relay KM1, a resistor R4, and a status indicator light. The base of the transistor Q1 is coupled to the output terminal of the processor through the resistor R4, the emitter is grounded, and the collector is coupled to one end of the coil of the relay KM1. The status indicator light is connected in series with the normally open contact of the relay KM1 and then connected to the power supply VCC. When the processing unit outputs a pulse signal, the transistor Q1 is intermittently turned on, and the relay KM1 is intermittently energized, causing the status indicator light to flash at the pulse frequency.

[0021] By adopting the above technical solution, the execution unit, through the cooperation of components such as transistor Q1 and relay KM1, will intermittently conduct with the pulse signal output by the processing unit, causing relay KM1 to intermittently close, so that the status indicator light connected in series with its normally open contact flashes at the pulse frequency, ensuring that the water immersion fault signal can be detected in time. The switching action of the transistor realizes effective control of the relay, improving the stability and reliability of the execution unit's operation, and allowing the status indication function to accurately respond to the signals of the processing unit.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The double-layer structure of the gateway shell, combined with the vacuum insulation cavity and aerogel, effectively improves the thermal insulation performance of the equipment.

[0024] 2. The multi-layered sealing structure and waterproof design significantly enhance the equipment's waterproof and moisture-proof capabilities, reducing the risk of malfunctions caused by water ingress.

[0025] 3. The water immersion fault circuit, through the coordinated work of the detection, processing and execution units, can monitor the water immersion status of the equipment in real time and issue timely warnings through status indicator lights, so that maintenance personnel can quickly find and deal with the problem.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a smart light pole multi-functional communication gateway terminal device.

[0032] Reference Figure 1 and Figure 2 A smart light pole multi-functional communication gateway terminal device has a gateway housing 1 with a double-layer structure design of inner shell 10 and outer shell 11. The vacuum heat insulation cavity 100 formed between the two is filled with aerogel. By utilizing the vacuum environment and the low thermal conductivity of aerogel, the influence of external high temperature / low temperature on internal components is effectively blocked, ensuring that the components work stably within a suitable temperature range.

[0033] The splicing joint of the gateway housing 1 adopts a carefully designed stepped sealing structure 12. The precise fit between the boss 120 and the groove 121 ensures that the contour of the boss 120 perfectly matches the inner cavity shape of the groove 121, forming a tight fit during splicing and structurally reducing gaps. The surface of the boss 120 is provided with an annular sealing groove 122. The depth and width of the groove are adapted to the size of the water-swellable rubber ring 123, ensuring that the water-swellable rubber ring 123 can fit tightly against the groove wall after being embedded, without loosening or shifting. When the gateway housing 1 is spliced ​​and assembled, the compression ring 124 pre-set on the inner wall of the groove 121 will be precisely aligned with the position of the annular sealing groove 122. As the gateway housing 1 is spliced ​​into place, the compression ring 124 will gradually embed into the annular sealing groove 122, forming a uniform and continuous compression force on the water-swellable rubber ring 123 in the groove, causing the water-swellable rubber ring 123 to deform to a certain extent and tightly fill the annular sealing groove. The space between the sealing groove 122 and the compression ring 124 forms the first reliable initial sealing barrier, effectively blocking most of the moisture intrusion. When encountering rain or moisture, the water-swellable rubber ring 123 embedded in the annular sealing groove 122 will respond quickly and expand in volume at an expansion ratio of 150%-300%, that is, the cross-sectional diameter increases to 9-18mm. This expansion can not only fill the small gaps between the rubber ring and the annular sealing groove 122 and the compression ring 124, but even if a larger gap of 5-10mm appears at the splice due to assembly errors, material aging or slight deformation after long-term use, the expanded rubber ring can fully fill these gaps, forming a tight fit with the contact surface of the boss 120 and the groove 121 without dead angles, achieving complete sealing, fundamentally blocking the path of moisture to seep into the interior of the housing through the splice, greatly improving the waterproof performance of the splice part of the gateway housing 1, and providing solid protection for the internal components.

[0034] A drain hole 13 is provided at the bottom of the gateway housing 1. A one-way drain valve 130 installed in the hole drains the small amount of water that has seeped into the gateway housing 1 outward, while preventing external water from flowing back in and avoiding water accumulation inside the housing that could damage the components.

[0035] The water immersion sensor 14 installed on the outer wall of the housing can sense changes in ambient humidity in real time, and the status indicator light 15 is used to provide feedback on the water immersion status of the device. Both are electrically connected to the water immersion fault circuit 3, and the water immersion fault circuit 3 manages the basic working mode of the status indicator light 15.

[0036] The gateway housing 1 is equipped with a waterproof connector 16 at the interface. The connector is made of high-density rubber material. While realizing the line connection, it prevents water vapor from entering from the interface through its good sealing performance and corrosion resistance, ensuring the long-term stable operation of the interface.

[0037] The surface of the arc-shaped guide plate 2 on the top of the gateway housing 1 is coated with a hydrophobic coating. When rainwater falls on the guide plate, it will quickly slide down the arc-shaped surface under the action of the hydrophobic coating, reducing the retention of rainwater on the top of the gateway housing 1 and reducing the possibility of rainwater seeping into the splice or interface.

[0038] Reference Figure 3 The detection unit 30 of the water immersion fault circuit 3 includes a humidity-sensitive resistor RS and a resistor R1, which together form a voltage divider circuit. The humidity-sensitive resistor RS is located on the outside of the gateway housing 1 and can directly sense changes in the humidity of the external environment. When there is a difference in the surrounding humidity, the resistance value of the humidity-sensitive resistor RS will change accordingly, thereby causing the voltage divider circuit to output a voltage signal corresponding to the current humidity. This voltage signal is transmitted as a detection signal to the non-inverting input of the operational amplifier N1 in the processing unit 31.

[0039] The processing unit 31 consists of an operational amplifier N1 and a threshold adjustment module. The threshold adjustment module includes two resistors R1 and R2. The voltage divider circuit formed by these two resistors provides a stable threshold voltage to the inverting input terminal of the operational amplifier N1. The operational amplifier N1 compares the voltage signal received from the detection unit 30 at the non-inverting input terminal with the threshold voltage at the inverting input terminal. When the humidity corresponding to the detected voltage signal exceeds the preset threshold, the operational amplifier N1 outputs a processing signal to the execution unit 32.

[0040] The execution unit 32 includes a transistor Q1, a relay KM1, a resistor R4, and a status indicator 15. The base of the transistor Q1 is connected to the output terminal of the processing unit 31 through the resistor R4, the emitter is grounded, and the collector is connected to one end of the coil of the relay KM1. The status indicator 15 is connected in series with the normally open contact of the relay KM1 and then connected to the power supply VCC. When the processing unit 31 outputs a pulse-type processing signal, the transistor Q1 will conduct intermittently with the pulse signal, causing the coil of the relay KM1 to be energized intermittently. The normally open contact of the relay KM1 will also be energized intermittently, thereby causing the status indicator 15 to flash according to the frequency of the pulse signal, thus outputting a status signal corresponding to the degree of water immersion, and accurately and clearly realizing the warning function of water immersion fault.

[0041] The implementation principle of a smart light pole multi-functional communication gateway terminal device in this application embodiment is as follows:

[0042] The vacuum insulation cavity 100 formed by the inner shell 10 and the outer shell 11, filled with aerogel, utilizes the insulation properties of vacuum and aerogel to block external temperature influences, providing a stable temperature environment for internal components. In the stepped sealing structure 12, the fitting of the boss 120 and the groove 121 with the water-swellable rubber ring 123 forms a basic seal during initial assembly through the compression ring 124. After contact with water, the rubber ring expands to achieve a complete seal of the gap. Combined with the waterproof joint 16 at the interface and the hydrophobic coating of the top arc-shaped guide plate 2, a comprehensive waterproof barrier is constructed, with drainage at the bottom. Hole 13 and one-way drain valve 130 can promptly drain any small amount of water that may seep in, further enhancing waterproofing and drainage capabilities. Water immersion sensor 14 monitors in real time. The detection unit 30 of water immersion fault circuit 3 converts the humidity signal into a voltage signal. After being compared with a preset threshold by processing unit 31, the execution unit 32 controls the status indicator 15 to output a corresponding flashing signal, ensuring that a timely warning is issued when water immersion occurs. The equipment achieves an organic combination of heat insulation, waterproofing, drainage and water immersion monitoring, thereby maintaining stable operation in complex outdoor environments and improving the reliability and service life of the equipment.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
