Description

Technical Field

[0001] This utility model relates to the field of intrinsically safe gateway technology, specifically to an intrinsically safe gateway for mining applications. Background Technology

[0002] Mining gateways are industrial-grade network devices specifically designed for the complex, high-risk, and highly interference-prone environments of mines. Their core function is to establish a data channel between underground mines and surface monitoring and management systems, solving the problem of data silos among heterogeneous underground equipment and enabling real-time acquisition, protocol conversion, and reliable transmission of data related to underground production, safety, and equipment status.

[0003] Existing intrinsically safe gateways, limited by intrinsically safe explosion-proof standards, mostly adopt a fully sealed structure design. However, when the gateway is running, its internal chips, protocol conversion modules and interface circuits will continuously generate heat. The sealed structure significantly blocks the effective heat dissipation path. As the gateway works continuously for a long time, the internal heat accumulates, causing the overall temperature of the gateway to rise continuously and leading to the performance degradation of core components. Therefore, an intrinsically safe gateway for mining is proposed. Utility Model Content

The heat exchanger is located on the outside of the fixed box and is used to guide the air. The air guide is located on the outside of the heat exchanger and is used to guide the airflow. The air guide works with the heat exchanger to cool the air.

[0009] Furthermore, the outer side of the fixing box is also provided with an interface, and there are multiple interfaces.

[0011] Furthermore, the air guide includes a heat-conducting frame, which is sleeved on the outside of the fixed box. A first heat sink is provided on the outside of the heat-conducting frame, and there are multiple first heat sinks. A fixed cover is sleeved on the outside of the first heat sink, and the fixed cover is connected to the fixed box. The fixed cover has at least one through groove on the side of the fixed box relative to the fixed box.

[0028] like Figures 1 to 6As shown, the intrinsically safe gateway for mining includes: a fixed box 1, which is open on one side, with a cover plate 101 rotatably connected to the open side of the fixed box 1; a connecting pipe 102 and a fixed plate 103 are respectively provided inside the fixed box 1; an air outlet 104 is opened on the outside of the connecting pipe 102, and a fan 106 is provided on the outside of the air outlet 104; one end of the connecting pipe 102 passes through the fixed box 1; and a heat dissipation assembly, which is located on the outside of the fixed box 1 and is used to dissipate heat from the air. The heat dissipation assembly includes an air guide 2 and a heat exchanger 3. The heat exchanger 3 is located on the outside of the fixed box 1 and is used to guide the air; the air guide 2 is located on the outside of the heat exchanger 3 and is used to guide the airflow. The air guide 2 works with the heat exchanger 3 to cool the air. Specifically, after use... During the process, the gateway is installed by the cooperation of the fixing box 1 and the fixing plate 103, so that the fixing box 1 and the cover plate 101 seal the gateway. During the use of the gateway, the air inside the fixing box 1 is dissipated by the cooperation of the air guide 2 and the heat exchanger 3 to ensure the temperature stability of the gateway during use. The connecting pipe 102 guides the air during use, so that the air can circulate inside the air guide 2 and the fixing box 1. A sealing strip is also provided between the fixing box 1 and the cover plate 101 to seal the gateway during use. The fan 106 can control the air during use, so that the air flows upward from the bottom of the fixing box 1. During use, the gateway is installed on the outside of the fixing plate 103 by bolts or clips.

[0029] like Figures 1 to 6 As shown, the outer side of the fixed box 1 is also equipped with multiple interfaces. Specifically, the interfaces adopt a mining-grade waterproof and explosion-proof structure design, and the number is set according to the gateway's functional requirements. They can be connected to underground sensors, actuators, and transmission cables to realize data access and command issuance for multiple types of equipment. Each interface is equipped with a dedicated sealing connector with a double sealing ring inside. When the wire is inserted into the interface, tightening the connector nut will make the sealing ring tightly wrap the outer sheath of the wire and the inner wall of the interface. This can prevent underground water and dust from seeping into the interface and causing a short circuit, and also avoid generating electrical sparks at the interface.

[0030] like Figures 1 to 6As shown, the heat exchanger 3 includes a fixed box 301, which is located on top of the fixed box 1. The fixed box 301 is hollow inside, and an air inlet groove 304 is provided inside the fixed box 301, which penetrates both the fixed box 301 and the fixed box 1. A guide plate 303 is provided inside the fixed box 301, and the guide plate 303 is located between the air inlet groove 304 and the connecting pipe 102. Specifically, the fixed box 301 is fixed to the top of the fixed box 1 by bolts. The sealing gasket between the two mating surfaces is made of flexible graphite material, which can effectively seal the assembly gap between the fixed box 301 and the fixed box 1, prevent circulating air leakage from affecting the heat dissipation efficiency, and isolate external impurities from entering the heat exchange system. The air inlet groove 304 penetrates the fixed box 301 and the fixed box 1 at an angle, and its channel... The walls are smoothed to reduce airflow resistance, ensuring that the hot air from the connecting pipe 102 can smoothly enter the fixed box 301. The guide plate 303 adopts a wave-shaped structure design and is inclinedly set at the junction of the air inlet slot 304 and the connecting pipe 102. On the one hand, it can guide the hot air to be evenly dispersed into the fixed box 301, avoiding local air accumulation. On the other hand, the guide plate 303 is made of aluminum alloy thermally conductive material and fits tightly against the inner wall of the fixed box 301. It can absorb some of the heat in the hot air and transfer it to the outer wall of the box to assist in cooling. When the hot air comes into contact with the guide plate 303, the airflow direction changes, which, together with the subsequently set disturbance plate 302, further prolongs the residence time of the air in the fixed box 301 and ensures sufficient heat exchange.

[0031] like Figures 1 to 6As shown, the air guide component 2 includes a heat-conducting frame 202, which is sleeved on the outside of the fixed box 301. Multiple first heat sinks 203 are provided on the outside of the heat-conducting frame 202. A fixing cover 201 is sleeved on the outside of the first heat sinks 203, and the fixing cover 201 is connected to the fixed box 1. The fixing cover 201 has at least one through slot 204 on the side opposite to the fixed box 1. Specifically, the heat-conducting frame 202 is an integrally formed copper alloy frame, tightly sleeved on the outside of the fixed box 301, and fixedly connected to the outer wall of the fixed box 301 and the end of the air guide plate 303 by welding, achieving rapid heat transfer and avoiding local heat accumulation. The first heat sinks 203 are sheet-like aluminum structures, and their number is evenly distributed on the outside of the heat-conducting frame 202 according to its size. The first heat sinks 203 ensure air energy transfer. The design ensures smooth airflow and maximizes the contact area between the heat-conducting frame 202 and the outside air. The fixed cover 201 is made of flame-retardant plastic and is connected to the top edge of the fixed box 1 by a buckle, forming a closed airflow channel. The through slot 204 is located on the side of the fixed cover 201 near the fixed box 1, which can guide the outside cold air to enter the airflow channel at a uniform speed from the bottom of the through slot 204. As the first heat sink 203 absorbs heat, the air in the channel is heated. The hot air flows upward because its density is reduced. The top of the fixed cover 201 has a gradually narrowing conical structure, which reduces the cross-sectional area of ​​the channel. According to the principle of fluid mechanics, the airflow speed will increase as the cross-sectional area decreases, accelerating the discharge of hot air. At the same time, it drives the outside cold air to continuously replenish from the through slot 204, forming efficient natural convection heat dissipation. Even in a windless environment underground, stable heat dissipation can be achieved.

[0032] like Figures 1 to 6 As shown, the fixed box 301 is also equipped with a disturbance plate 302. There are multiple disturbance plates 302. A heat conduction plate 305 is provided on the outside of the disturbance plate 302. At least one second heat sink 306 is provided on the outside of the heat conduction plate 305. Specifically, the disturbance plate 302 is made of thin aluminum alloy. When hot air enters the fixed box 301, the airflow will change its flow direction under the obstruction of the disturbance plate 302, forming a vortex, which prolongs the flow path of the air in the fixed box 301 and ensures that the hot air is in full contact with the disturbance plate 302 and the guide plate 303. The second heat sink 306 is a needle-shaped copper structure, which is evenly distributed on the side of the heat conduction plate 305 away from the disturbance plate 302. The needle-shaped structure can further increase the contact area with the air inside the fixed box 301, and quickly dissipate the heat transferred by the heat conduction plate 305 into the airflow inside the fixed box 301, and then be led out to the air guide 2 with the airflow, thereby improving the overall heat dissipation effect.

[0033] like Figures 1 to 6As shown, the fixed box 1 is also equipped with an air guide plate 105. Specifically, the air guide plate 105 is made of arc-shaped aluminum alloy plate and is detachably connected to the side of the fixed box 1 near the air inlet slot 304 by buckles or bolts. When the gateway is running, the air at the bottom of the fixed box 1 is driven upward by the fan 106 and becomes hot air after flowing through the core component area. At this time, the arc-shaped structure of the air guide plate 105 can guide the hot air, prevent the hot air from diffusing to both sides of the fixed box 1, and force the hot air to concentrate and flow towards the inlet of the air inlet slot 304, reducing the resistance when the airflow enters the air inlet slot 304 and ensuring that the hot air can enter the fixed box 301 with a stable flow rate.

[0034] like Figures 1 to 6 As shown, the working state of this intrinsically safe gateway for mining is as follows: When the gateway is in use, the core module of the gateway is first installed and fixed by bolts or buckles through the cooperation of the fixing box 1 and the fixing plate 103. At the same time, the fixing box 1 and the cover plate 101 are sealed by sealing strips, the fixing box 1 and the fixing box 301 are sealed by sealing gaskets, and each interface is sealed by special sealing joints, forming a closed structure that meets the intrinsically safe explosion-proof standard. Subsequently, the intrinsically safe fan 106 drives the air to flow upward from the bottom of the fixing box 1, which is guided by the connecting pipe 102 and distributed by the air outlet 104. Then, the air is concentrated and guided by the inclined air guide plate 105 to enter the air inlet slot 304 and enter the interior of the fixing box 301. The hot air entering the fixing box 301 forms a vortex under the action of the staggered disturbance plates 302. The air remains in contact with the wave-shaped guide plate 303 for initial heat exchange. Then, the heat absorbed by the disturbance plate 302 is transferred to the second heat sink 306 via the heat conduction plate 305 for further dissipation. The cooled air enters the heat conduction frame 202 fitted on the outside of the fixed box 301. The heat is transferred to the first heat sink 203 on the outside through the heat conduction frame 202. Under the guidance of the fixed cover 201, the outside cold air enters from the bottom of the channel 204 and exchanges heat with the first heat sink 203. The heated air accelerates upward and is discharged along the top constriction structure of the fixed cover 201. Finally, a closed-loop airflow circulation is formed, in which heat is absorbed inside the fixed box, cooled inside the heat exchange component 3, and dissipated outside the air guide component 2. This continuously removes heat from the core components, ensuring the gateway temperature is stable and avoiding performance degradation.

[0035] In summary, this utility model includes: a fixed box 1, which is open on one side, with a cover plate 101 rotatably connected to the open side of the fixed box 1; a connecting pipe 102 and a fixed plate 103 are respectively provided inside the fixed box 1; an air outlet 104 is provided on the outside of the connecting pipe 102; a fan 106 is provided on the outside of the air outlet 104; and one end of the connecting pipe 102 passes through the fixed box 1; a heat dissipation assembly is provided on the outside of the fixed box 1 for dissipating air heat, and the heat dissipation assembly includes an air guide 2 and a heat exchanger 3. The heat exchanger 3 is provided on the outside of the fixed box 1 for guiding air... The air guide 2 is located on the outside of the heat exchanger 3 to guide the airflow, and the air guide 2 works with the heat exchanger 3 to cool the air. This utility model, through the arrangement of the fixed box 1 and the heat exchanger 3, achieves the cooling of the air inside the fixed box 1 during use by cooperating with the cover plate 101, the connecting pipe 102, the air outlet 104, the fixed box 301, the disturbance plate 302, the guide plate 303, the air inlet slot 304, the heat conduction plate 305, and the second heat sink 306, thereby preventing the gateway temperature from rising continuously and causing the performance degradation of the core components.
