[0032] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present disclosure and should not be construed as a limitation of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0033] As Figure 1 、 Figure 2 、 Figure 5 and Figure 7 shown, an intrinsically safe waterproof mine gateway proposed by an embodiment of the present disclosure includes: a housing 1, a circuit board 2, a cover plate 3, a first flange 4 and a second flange 5. The housing 1 includes: a top plate 11 and a bottom plate 12 located opposite to each other and an opening 13 located between the top plate 11 and the bottom plate 12. The circuit board 2 is arranged inside the housing 1. The cover plate 3 is detachably covered on the opening 13. The first flange 4 is arranged at one end of the top plate 11 close to the opening 13, and the side surface of the first flange 4 close to the bottom plate 12 abuts against the first end of the cover plate 3. The second flange 5 is arranged at one end of the bottom plate 12 close to the opening 13, and the side surface of the second flange 5 close to the top plate 11 abuts against the second end of the cover plate 3.

[0034] It can be understood that since the cover plate 3 is detachably covered on the opening 13 and the circuit board 2 is arranged inside the housing 1, the gateway can utilize the circuit board 2 to realize the communication function, and at the same time, can utilize the closed structure formed by the cooperation of the housing 1 and the cover plate 3 to protect the circuit board 2, and is convenient for the disassembly, installation and maintenance of the circuit board 2.

[0035] Among them, since the first flange 4 is arranged at one end of the top plate 11 close to the opening 13, and the side surface of the first flange 4 close to the bottom plate 12 abuts against the first end of the cover plate 3, the assembly gap between the top plate 11 and the cover plate 3 is located on the opening 13 side of the housing 1, so as to ensure that the top of the housing 1 is a complete and closed plate structure. Moreover, since the second flange 5 is arranged at one end of the bottom plate 12 close to the opening 13, and the side surface of the second flange 5 close to the top plate 11 abuts against the second end of the cover plate 3, the assembly gap between the bottom plate 12 and the cover plate 3 is located on the opening 13 side of the housing 1, so as to ensure that the bottom of the housing 1 is a complete and closed plate structure. Thus, through the arrangement of the first flange 4 and the second flange 5, the assembly gaps at the top and bottom of the gateway are avoided. Therefore, when the gateway is applied outdoors, the water accumulation at the top and bottom of the gateway cannot seep in, further preventing the gateway from malfunctioning due to water seepage and ensuring high communication quality and efficiency.

[0036] It should be noted that the housing 1, as the main structure of the gateway, is used to carry components such as the circuit board 2. The specific type of the housing 1 can be set according to actual needs, and there is no limitation in this regard. For example, the housing 1 can be a structure close to a cuboid. The housing 1 has a top plate 11, a bottom plate 12, two side plates 14 and a back plate. The top plate 11 is located at the top of the housing 1, the bottom plate 12 is located at the bottom of the housing 1, the two side plates 14 are respectively located on the sides of the housing 1, the back plate is arranged opposite to the opening 13, and the back plate is located at the back of the housing 1; the housing 1 can be made of materials such as stainless steel.

[0037] The cover plate 3 is used to cover the opening 13 of the housing 1 to achieve the enclosure of the housing 1. The specific type of the cover plate 3 can be set according to actual needs, and there is no limitation in this regard. For example, the cover plate 3 can be a plate structure made of materials such as stainless steel, and the cover plate 3 can be detachably covered on the opening 13 by means such as bolt fixation or snap fixation.

[0038] Among them, in related embodiments, when the cover plate 3 covers the opening 13, the assembly gap between the cover plate 3 and the top plate 11 is located at the top of the housing 1, and the assembly gap between the cover plate 3 and the bottom plate 12 is located at the bottom of the housing 1. However, in this embodiment, due to the arrangement of the first flange 4 and the second flange 5, the assembly gap between the cover plate 3 and the top plate 11 and the assembly gap between the cover plate 3 and the bottom plate 12 are respectively transferred to the opening 13 side of the housing 1, thus realizing the waterproofing of the top and bottom of the gateway.

[0039] The circuit board 2 is used for signal reception, transmission, processing, conversion, etc. The specific type of the circuit board 2 can be set according to actual needs, and there is no limitation in this regard.

[0040] The first flange 4 is an extension structure of the top plate 11 for waterproofing the top of the gateway. The specific type of the first flange 4 can be set according to actual needs, and there is no limitation in this regard. For example, the first flange 4 can be integrally formed with the top plate 11.

[0041] The second flange 5 is an extension structure of the bottom plate 12 for waterproofing the bottom of the gateway. The specific type of the second flange 5 can be set according to actual needs, and there is no limitation in this regard. For example, the second flange 5 can be integrally formed with the bottom plate 12.

[0042] As Figure 1 、 Figure 5 and Figure 6 shown, in some embodiments, the gateway further includes: a plurality of bolts 6. The bolt 6 includes: a connected first threaded portion 61 and a first head 62. The first threaded portion 61 penetrates through the cover plate 3 and is threadedly arranged on the housing 1, and the first head 62 abuts against the side surface of the cover plate 3 away from the housing 1.

[0043] It can be understood that since the first threaded portion 61 penetrates through the cover plate 3 and is threadedly arranged on the housing 1, and the first head 62 abuts against the side surface of the cover plate 3 away from the housing 1, the cover plate 3 can be fixed on the housing 1 by means of a plurality of bolts 6, thus ensuring the stable closing of the opening 13. At the same time, it is also convenient for the disassembly of the cover plate 3, making the use of the gateway more flexible and convenient.

[0044] It should be noted that the first threaded portion 61 and the first head 62 of the bolt 6 cooperate to fix the cover plate 3 on the housing 1. The specific types of the first threaded portion 61 and the first head 62 can be set according to actual needs, and there is no limitation in this regard. For example, the first threaded portion 61 is provided with an external thread adapted to the threaded hole on the housing 1, the cover plate 3 is provided with a counterbore for the first threaded portion 61 to penetrate through, and the diameter of the first threaded portion 61 is smaller than the diameter of the first head 62.

[0045] The number of bolts 6 can be set according to actual needs, and there is no limitation in this regard. For example, the bolts 6 can be two, three, four, five, etc. Among them, a plurality of bolts 6 are evenly distributed along the circumference of the opening 13.

[0046] As Figure 6 shown, in some embodiments, the bolt 6 further includes: an intermediate rod 63 and a snap ring 64. The intermediate rod 63 is arranged between the first threaded portion 61 and the first head 62. The snap ring 64 is sleeved on the intermediate rod 63, and the inner diameter of the snap ring 64 is greater than the diameter of the intermediate rod 63 and smaller than the diameter of the first threaded portion 61.

[0047] It can be understood that since the intermediate rod 63 is disposed between the first threaded portion 61 and the first head 62, the first head 62, the intermediate rod 63 and the first threaded portion 61 form a bolt 6 of an integral structure. And since the snap ring 64 is sleeved on the intermediate rod 63, and the inner diameter of the snap ring 64 is greater than the diameter of the intermediate rod 63 and less than the diameter of the first threaded portion 61, the snap ring 64 can limit the first threaded portion 61, thereby preventing the bolt 6 from falling off the cover plate 3, and further making the disassembly and assembly of the gateway more efficient and convenient.

[0048] It should be noted that the intermediate rod 63 is used to connect the first threaded portion 61 and the first head 62, and to carry the snap ring 64. The specific type of the intermediate rod 63 can be set according to actual needs, and no limitation is imposed thereon.

[0049] The snap ring 64 is used to limit the bolt 6 on the cover plate 3. At the same time, by using the elasticity of the snap ring 64, the stable fixation of the bolt 6 to the cover plate 3 can also be ensured. The specific type of the snap ring 64 can be set according to actual needs, and no limitation is imposed thereon.

[0050] As Figure 5 and Figure 6 shown, in some embodiments, the housing 1 further includes: a middle frame 15 and a first sealing ring 16. The middle frame 15 is arranged along the circumference of the opening 13, and the first threaded portion 61 of the bolt 6 penetrates through the cover plate 3 and is threadedly arranged on the middle frame 15. The first sealing ring 16 is arranged along the circumference of the opening 13, and the first sealing ring 16 abuts between the cover plate 3 and the middle frame 15.

[0051] It can be understood that since the middle frame 15 is arranged along the circumference of the opening 13, and the first threaded portion 61 of the bolt 6 penetrates through the cover plate 3 and is threadedly arranged on the middle frame 15, the housing 1 can use the middle frame 15 to achieve stable bearing of the bolt 6, thereby ensuring the stable covering of the cover plate 3 on the opening 13. At the same time, since the first sealing ring 16 is arranged along the circumference of the opening 13, and the first sealing ring 16 abuts between the cover plate 3 and the middle frame 15, the cover plate 3 and the middle frame 15 can be sealed by using the first sealing ring 16, thereby effectively improving the waterproof performance of the gateway.

[0052] It should be noted that the middle frame 15 is used to achieve the bearing of the bolt 6. The specific type of the middle frame 15 can be set according to actual needs, and no limitation is imposed thereon. For example, the middle frame 15 can be an annular plate structure with a certain width, and the middle frame 15 is arranged on the top plate 11, the bottom plate 12 and the side plate 14 of the housing 1.

[0053] The first sealing ring 16 is used for sealing between the cover plate 3 and the middle frame 15. The specific type of the first sealing ring 16 can be set according to actual needs, and no limitation is imposed thereon. For example, the first sealing ring 16 can be a rubber washer.

[0054] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, in some embodiments, the gateway further includes: a first connector 7 and an antenna 8. The first connector 7 includes: a second threaded portion 71, a second head 72 and a first nut 73 that are connected. The second threaded portion 71 penetrates through the top plate 11 and is threadedly connected to the first nut 73, and the second head 72 abuts against the side of the top plate 11 close to the bottom plate 12, and the first nut 73 abuts against the side of the top plate 11 away from the bottom plate 12. The antenna 8 is threadedly sleeved on the second threaded portion 71 and abuts against the first nut 73. Wherein, the communication end of the circuit board 2 is connected to the second head 72, and the communication end of the antenna 8 is connected to the second threaded portion 71.

[0055] It can be understood that, since the second threaded portion 71 penetrates through the top plate 11 and is threadedly connected to the first nut 73, and the second head 72 abuts against the side of the top plate 11 close to the bottom plate 12, and the first nut 73 abuts against the side of the top plate 11 away from the bottom plate 12, the second threaded portion 71 realizes stable setting on the top plate 11 by the cooperation of the second head 72 and the first nut 73. At the same time, since the antenna 8 is threadedly sleeved on the second threaded portion 71 and abuts against the first nut 73, the antenna 8 can be stably set on the top plate 11 by the second threaded portion 71. And, since the communication end of the circuit board 2 is connected to the second head 72, and the communication end of the antenna 8 is connected to the second threaded portion 71, communication can also be realized between the antenna 8 and the circuit board 2 by the first connector 7. Thus, the installation of the antenna 8 is realized by the first connector 7, so that the gateway can realize high-performance wireless communication by the antenna 8.

[0056] It should be noted that the second threaded portion 71, the second head 72 and the first nut 73 of the first connector 7 are cooperatively fixed on the top plate 11. The specific types of the second threaded portion 71, the second head 72 and the first nut 73 can be set according to actual needs, and no limitation is made thereto. By way of example, the second threaded portion 71 is provided with an external thread adapted to the internal thread of the first nut 73, and the diameter of the second threaded portion 71 is smaller than the diameter of the second head 72.

[0057] The antenna 8 is used for the wireless communication of the gateway. The specific type of the antenna 8 can be set according to actual needs, and no limitation is made thereto. By way of example, the antenna 8 has a sleeve, and a pin is provided at the central axis of the sleeve. A jack is provided at the central axis of the second threaded portion 71. The sleeve is threadedly sleeved on the second threaded portion 71, and the pin is inserted into the jack.

[0058] As Figure 3As shown, in some embodiments, the top plate 11 is provided with a through hole 17, and a first cut surface 18 is provided on one side of the through hole 17. A second cut surface 74 is provided on one side of the second threaded portion 71. The second threaded portion 71 penetrates through the through hole 17, and the first cut surface 18 and the second cut surface 74 are in contact with each other.

[0059] It can be understood that since the second threaded portion 71 penetrates through the through hole 17, and the first cut surface 18 and the second cut surface 74 are in contact with each other, when the first joint 7 is installed on the top plate 11, circumferential limitation can be achieved by the cooperation of the first cut surface 18 and the second cut surface 74, thereby avoiding the synchronous rotation between the second threaded portion 71 and the first nut 73 and the synchronous rotation between the second threaded portion 71 and the antenna 8, and further ensuring the efficient installation of the antenna 8.

[0060] It should be noted that the cooperation of the first cut surface 18 and the second cut surface 74 to achieve the circumferential limitation of the second threaded portion 71 can not only avoid the slipping problem during the installation of the first joint 7, but also prevent the loosening of the first joint 7 while the antenna 8 realizes the rotation function. Among them, the first cut surface 18 makes the through hole 17 form a D-shaped hole, and the second cut surface 74 makes the second threaded portion 71 form a D-shaped threaded post.

[0061] As Figure 3 shown, in some embodiments, the first joint 7 further includes: a second sealing ring 76. A sealing groove 75 is provided on the side surface of the second head 72 close to the top plate 11, and the sealing groove 75 is arranged along the circumference of the second threaded portion 71. The second sealing ring 76 is arranged in the sealing groove 75 and abuts against the side surface of the top plate 11 close to the bottom plate 12.

[0062] It can be understood that since the sealing groove 75 is arranged along the circumference of the second threaded portion 71, and the second sealing ring 76 is arranged in the sealing groove 75 and abuts against the side surface of the top plate 11 close to the bottom plate 12, the second head 72 and the top plate 11 can be sealed by the second sealing ring 76, thereby ensuring the high waterproof performance of the top plate 11 while ensuring the stable installation of the antenna 8.

[0063] It should be noted that the sealing groove 75 is used to accommodate the second sealing ring 76, and the specific type of the sealing groove 75 can be set according to actual needs, and no limitation is imposed thereon.

[0064] The second sealing ring 76 is used for the sealing between the second head 72 and the top plate 11. The specific type of the second sealing ring 76 can be set according to actual needs, and no limitation is imposed thereon. By way of example, the second sealing ring 76 can be a rubber washer.

[0065] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 7As shown, in some embodiments, the housing 1 further includes: two side plates 14 located between the top plate 11 and the bottom plate 12 and opposite to each other, and the top plate 11, the side plates 14 and the bottom plate 12 are arranged along the circumference of the opening 13; the gateway further includes: a plurality of second connectors 9, and the second connector 9 includes: a third threaded portion 91, a third head 92 and a second nut 93 that are connected. The third threaded portion 91 penetrates through the side plate 14 and is threadedly connected to the second nut 93, and the third head 92 abuts against the outer side surface of the side plate 14, and the second nut 93 abuts against the inner side surface of the side plate 14. Wherein, the communication end of the circuit board 2 is connected to the third threaded portion 91.

[0066] It can be understood that, since the third threaded portion 91 penetrates through the side plate 14 and is threadedly connected to the second nut 93, and the third head 92 abuts against the outer side surface of the side plate 14, and the second nut 93 abuts against the inner side surface of the side plate 14, the third threaded portion 91 realizes stable setting on the side plate 14 by the cooperation of the third head 92 and the second nut 93. At the same time, since the communication end of the circuit board 2 is connected to the third threaded portion 91, the circuit board 2 can realize wired communication with external devices by using the second connector 9.

[0067] It should be noted that the third threaded portion 91, the third head 92 and the second nut 93 of the second connector 9 are cooperatively fixed on the side plate 14, and the specific types of the third threaded portion 91, the third head 92 and the second nut 93 can be set according to actual needs, and there is no limitation thereto. By way of example, the third threaded portion 91 is provided with an external thread adapted to the internal thread of the second nut 93, the diameter of the third threaded portion 91 is smaller than the diameter of the third head 92, the third head 92 has an interface structure connected to the communication cable, and a communication channel connecting the interface of the third head 92 and the circuit board 2 is provided inside the third threaded portion 91.

[0068] As Figure 7 shown, in some embodiments, a plurality of card slots 19 are provided on the outer side surface of the side plate 14, at least one corner is provided on the circumference of the card slot 19, and at least one rib groove is provided on the circumference of the third head 92. The third head 92 is clamped in the card slot 19, and the corner is clamped in the rib groove.

[0069] It can be understood that, since the third head 92 is clamped in the card slot 19 and the corner is clamped in the rib groove, the third head 92 can realize circumferential limit in the card slot 19 by the cooperation of the corner and the rib groove, thereby avoiding the synchronous rotation between the third threaded portion 91 and the second nut 93, and further ensuring the efficient installation of the second connector 9.

[0070] It should be noted that the card slot 19 is used to accommodate the third head 92 and, at the same time, cooperate with the rib groove to realize the circumferential limit of the second connector 9. The specific type of the card slot 19 can be set according to actual needs, and there is no limitation thereto.

[0071] The edges and corners cooperate with the edge grooves to achieve circumferential limitation of the second joint 9. The specific types of the edges and corners can be set according to actual needs, and there is no limitation thereto. By way of example, multiple edges and corners make the third head 92 form a hexagonal prism structure, and multiple edge grooves make the clamping groove 19 form a hexagonal groove structure.

[0072] In some embodiments, the second joint 9 further includes: a third sealing ring, which is arranged circumferentially along the third threaded portion 91, and the third sealing ring abuts between the second nut 93 and the side plate 14.

[0073] It can be understood that since the third sealing ring is arranged circumferentially along the third threaded portion 91 and the third sealing ring abuts between the second nut 93 and the side plate 14, the second nut 93 and the side plate 14 can be sealed by the third sealing ring, so as to ensure relatively high waterproof performance of the side plate 14 while realizing wired communication of the gateway.
