Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a portable wireless substation for mining. Background Art

[0002] The environment of non-coal mines is complex and changeable, and the traditional manual driving method has safety risks and efficiency limitations. Therefore, in the non-coal mine environment, communication and automation technologies are usually used to realize the intelligent operation and management of mining equipment to improve work efficiency, work safety and reduce the risk of human operation. At present, the intelligent driving system of non-coal mines not only includes remote driving and unmanned driving of vehicles, but also involves vehicle systems, wireless communication systems, and the management and control systems of the entire intelligent mine. Therefore, it is necessary to establish full coverage of underground wireless networks to ensure the real-time online operation of various intelligent devices and systems to support the intelligent operation of mines. As a result, the number of sensors used in non-coal mines is increasing, and a large amount of image and video data needs to be collected and transmitted.

[0003] However, in order to meet the needs of data transmission, the existing mine wireless substations usually contain a large number of electronic components and antenna arrays, which makes them bulky and heavy. In the limited space environment of mines, such bulky substations are obviously not conducive to layout and maintenance. For example, each time they are arranged, they need to be unpacked, wired and other preliminary preparations, which makes their layout extremely inconvenient. Moreover, due to the size and weight of the substations, they require a large floor space for installation and operation. In the complex environment of the mine, the available space is very valuable, so the substations with a large floor space will limit the space for other equipment and operations. Furthermore, the mine operation area often changes, and the substations need to be able to move flexibly to adapt to different operation requirements. However, the bulky characteristics of the existing substations limit their mobility, making it difficult to quickly arrange and reconfigure them in the mine. For example, when blasting underground, the wiring of the equipment needs to be removed in advance, the equipment needs to be stored and placed, and then the equipment needs to be moved out of the mine before the underground blasting can be carried out, which greatly reduces the underground operation efficiency. Therefore, it is necessary to improve it. Utility Model Content

Unless otherwise specified, the "connection" described in this article can be a direct connection or an indirect connection, that is, a connection through an intermediate.

[0055] In view of the problems existing in the existing technology, such as Figure 1 and Figure 2 As shown, in this example, the utility model provides a portable wireless substation for mining, which is a general type of wireless substation for mining, including: a bracket 10, an equipment box 20, an antenna 30, a power box 40, a first snap-in assembly 50, a second snap-in assembly 60 and a third snap-in assembly 70. Among them, the bracket 10 is used for detachable connection with the target wall; the equipment box 20 is detachably connected to the bracket 10 through the first snap-in assembly 50, so that the bracket 10 and the equipment box 20 can be conveniently disassembled or installed, thereby improving the convenience and mobility of the bracket 10 and the equipment box 20; the antenna 30 is communicatively connected to the equipment in the equipment box 20, and the antenna 30 is used to receive and send signals, that is, the antenna 30 transmits the signal to the equipment in the equipment box 20 after receiving the signal, or the antenna 30 sends the signal that the equipment in the equipment box 20 needs to send, and the antenna 30 sends the signal through The second snap-in assembly 60 is detachably connected to the bracket 10, so that the bracket 10 and the antenna 30 can be easily disassembled or installed, thereby improving the convenience and mobility of the bracket 10 and the antenna 30; the battery in the power box 40 is electrically connected to the equipment in the device box 20, so that the power box 40 supplies power to the equipment in the device box 20, and the power box 40 is detachably connected to the device box 20 through the third snap-in assembly 70, so that the device box 20 and the power box 40 can be easily disassembled or installed, thereby improving the convenience and mobility of the device box 20 and the power box 40. In an underground application environment, when installation is required, the bracket 10 is first hung on the underground wall, and then the device box 20 and the antenna 30 are snap-connected to the bracket 10, and finally the power box 40 is snap-connected to the device box 20, and the installation can be quickly completed. When disassembly is required, first separate the power box 40 from the equipment box 20, then separate the equipment box 20 and the antenna 30 from the bracket 10, and finally remove the bracket 10 from the underground wall, and disassembly can be completed quickly.

[0056] In a further example, if Figure 3 As shown, the bracket 10 has a mounting portion 11 and a connecting portion 12. Taking the underground application environment as an example, the mounting portion 11 has a mounting surface, which is parallel to the underground wall. The equipment box 20 is detachably connected to the mounting surface of the mounting portion 11 through a first clamping assembly 50, and the antenna 30 is detachably connected to the mounting surface of the mounting portion 11 through a second clamping assembly 60. Figure 1 As shown, the device box 20 is detachably connected to the lower end of the mounting surface of the mounting portion 11 through a first snap-fit ​​assembly 50, and the antenna 30 is detachably connected to the upper end of the mounting surface of the mounting portion 11 through a second snap-fit ​​assembly 60. This design allows the bracket 10 and the device box 20, as well as the bracket 10 and the antenna 30, to be easily disassembled or installed, thereby improving the ease of use and mobility of the device.

[0057] The connecting portion 12 has a connecting surface, which is perpendicular to the underground wall. A hanging ring 13 is arranged on the connecting surface of the connecting portion 12. The hanging ring 13 can be one or more. Figure 1 and Figure 2 A total of three hanging rings 13 are provided, and the hanging rings 13 and the connecting portion 12 can be fixedly connected, for example, by screws, or detachably connected, for example, by snaps, etc. When the hanger 10 needs to be hung on the underground wall, it is only necessary to put the hanging ring 13 on the hook on the underground wall. Such a design greatly facilitates the disassembly and hanging of the hanger 10 on the underground wall.

[0058] In this example, the first clamping assembly 50 includes a first clamping component 51 and a second clamping component 52. The first clamping component 51 is connected to the mounting surface of the mounting portion 11, and the second clamping component 52 is arranged on the equipment box 20. When the equipment box 20 needs to be installed on the mounting surface of the mounting portion 11, the second clamping component 52 and the first clamping component 51 are mutually clamped to realize that the equipment box 20 is detachably connected to the mounting surface of the mounting portion 11. Among them, the first clamping component 51 and the second clamping component 52 can be any components that can be clamped to each other, such as buckles, hooks, etc. For example, taking the application environment underground in a mine as the background, such as Figure 2 and Figure 7 As shown, the first clamping member 51 and the second clamping member 52 are both mountain-shaped hooks. When installation is required, the first clamping member 51 and the second clamping member 52 are clamped to each other, that is, the two mountain-shaped hooks are clamped to each other, so that the equipment box 20 can be detachably connected to the installation surface of the installation part 11.

[0059] In a further example, if Figure 8As shown, the first clamping member 51 includes a first fixing plate 511 and a first clamping plate 512. The first clamping plate 512 is disposed between the two first fixing plates 511, and both side ends of the first clamping plate 512 are fixedly connected to the two first fixing plates 511 respectively. Figure 2 As shown, the first fixing plate 511 is fixed to the mounting surface of the mounting portion 11 by screws, so that the first clamping member 51 is fixed to the mounting surface of the mounting portion 11. At this time, a first clamping groove (not shown) is formed between the first clamping plate 512 and the mounting surface of the mounting portion 11. Figure 7 As shown, the structure of the second clamping member 52 is similar to that of the first clamping member 51. The second clamping member 52 includes a second fixing plate 521 and a second clamping plate 522. The second clamping plate 522 is disposed between the two second fixing plates 521, and both side ends of the second clamping plate 522 are fixedly connected to the two second fixing plates 521. Figure 7 As shown, the second fixing plate 521 is fixed to the back of the device box 20 with screws, thereby fixing the second clamping member 52 to the outer shell of the device box 20. At this time, a second clamping groove (not shown) is formed between the second clamping plate 522 and the outer shell of the device box 20. When installation is required, the first clamping plate 512 is inserted into the second clamping groove, and the second clamping plate 522 is inserted into the first clamping groove, so that the first clamping member 51 and the second clamping member 52 are mutually clamped, so that the device box 20 can be detachably connected to the installation surface of the installation portion 11. In a further example, as Figure 3 As shown, the mounting surface of the mounting portion 11 is further provided with a plurality of mounting holes 111, and the first clamping member 51 is detachably connected to the mounting surface of the mounting portion 11 through the mounting holes 111, for example, by screws passing through the mounting holes 111 to mount the first clamping member 51 on the mounting surface of the mounting portion 11. According to actual installation requirements, the mounting holes 111 at different positions can also be selected for mounting the first clamping member 51, thereby changing the relative position between the bracket 10 and the equipment box 20 to meet the installation requirements.

[0060] In this example, the second clamping assembly 60 includes an antenna bracket 61 and a bracket fixing box 62. Figure 4 As shown, the antenna bracket 61 is connected to the antenna 30, and the bracket fixing box 62 is arranged on the mounting surface of the mounting portion 11, as shown in FIG. Figure 2 As shown, the bracket fixing box 62 is fixed to the upper end of the mounting surface of the mounting portion 11 by screws. When installation is required, the antenna bracket 61 is directly inserted into the bracket fixing box 62, so that the antenna 30 can be detachably connected to the mounting surface of the mounting portion 11, so that the antenna 30 and the bracket 10 can be easily disassembled or installed, thereby improving the convenience and mobility of the antenna 30 and the bracket 10. In a further example, Figure 5As shown, the bracket fixing box 62 also has an opening slot 621. When the antenna bracket 61 is inserted into the bracket fixing box 62, the antenna 30 passes through the opening slot 621 and extends out. This design can reduce the spatial restrictions of the bracket fixing box 62 on the antenna 30 after the components are installed, and the setting direction of the antenna 30 is also more flexible.

[0061] In this example, the third clamping assembly 70 includes a vertical limit assembly and a horizontal limit assembly. Among them, the vertical limit assembly is parallel to the bottom surface of the equipment box 20, and the vertical limit assembly is used to limit the movement of the power box 40 relative to the equipment box 20 in the vertical direction; the horizontal limit assembly is perpendicular to the bottom surface of the equipment box 20, and the horizontal limit assembly is used to limit the movement of the power box 40 relative to the equipment box 20 in the horizontal direction. With such a design, through the cooperation of the vertical limit assembly and the horizontal limit assembly, after the various components are installed, the movement of the power box 40 relative to the equipment box 20 in the horizontal and vertical directions is limited at the same time, that is, the positional relationship between the power box 40 and the equipment box 20 after connection is fixed, and the connection between the power box 40 and the equipment box 20 is realized. It should be noted that the vertical direction refers to the direction perpendicular to the bottom surface of the equipment box 20, and the horizontal direction refers to any direction within the plane where the bottom surface of the equipment box 20 is located.

[0062] In a further example, if Fig. 9 and Fig.11 As shown, the vertical limiter assembly includes a first limiter 71 and a second limiter 72. The first limiter 71 is arranged on the outer shell of the equipment box 20, and the second limiter 72 is arranged on the outer shell of the power box 40. The first limiter 71 and the second limiter 72 are mutually engaged, thereby limiting the movement of the power box 40 relative to the equipment box 20 in the vertical direction.

[0063] In a further specific example, for example Fig.10As shown, the first limiting member 71 includes a first mounting plate 711, a first connecting plate 712 and a first limiting plate 713. The first mounting plate 711 has a first side edge 7111, and the first mounting plate 711 is connected to the outer shell of the equipment box 20, for example, fixed to the bottom surface of the equipment box 20 by screws, adhesives, etc.; the first connecting plate 712 has a first side end 7121 and a second side end 7122, and the first side edge 7111 is connected to the first side end 7121, so that the first mounting plate 711 and the first connecting plate 712 are fixedly connected together; the first limiting plate 713 is arranged opposite to the first mounting plate 711, and the first limiting plate 713 is connected to the second side end 7122. Such a design allows the first mounting plate 711, the first connecting plate 712 and the first limiting plate 713 to form a first limiting groove 714 together. Similarly, the second stopper 72 is similar in structure to the first stopper 71, and includes a second mounting plate, a second connecting plate, and a second stopper plate. The second mounting plate has a second side edge, the second mounting plate is connected to the housing of the power supply box 40, the second connecting plate has a third side end and a fourth side end, the second side edge is connected to the third side end, the second stopper plate is arranged opposite to the second mounting plate, and the second stopper plate is connected to the fourth side end. Such a design allows the second mounting plate, the second connecting plate, and the second stopper plate to form a second stopper groove together. When the device box 20 and the power box 40 are installed, the first limit plate 713 is slid into the second limit slot, and at the same time, the second limit plate is slid into the first limit slot 714, so that the first limit plate 713 is stuck in the second limit slot, and the second limit plate is stuck in the first limit slot 714, so that the first limit member 71 and the second limit member 72 are mutually engaged. When the power box 40 wants to move away from the device box 20 in the vertical direction, the first limit plate 713 will press against the second limit plate, thereby limiting the vertical movement of the power box 40 relative to the device box 20. In a further example, Fig.10 As shown, a first stopper plate 715 is provided in the first limiting groove 714, and the first stopper plate 715 is fixedly connected to at least one of the first mounting plate 711, the first connecting plate 712 and the first limiting plate 713, so that when the second limiting plate is slidably inserted into the first limiting groove 714, it will not slide out of the first limiting groove 714. Similarly, a second stopper plate is provided in the second limiting groove, and the second stopper plate is fixedly connected to at least one of the second mounting plate, the second connecting plate and the second limiting plate, so that when the first limiting plate 713 is slidably inserted into the second limiting groove, it will not slide out of the second limiting groove.

[0064] In a further example, if Fig. 9 and Fig.12As shown, the horizontal limit assembly includes a latch 73 and a socket box 74. The latch 73 is arranged on the housing of the power box 40, and the latch 73 has a retractable latch head 731. The socket box 74 is arranged on the housing of the equipment box 20, and the socket box 74 has a latch hole 741 corresponding to the latch head 731. Taking the underground application of a mine as an example, when the equipment box 20 and the power box 40 are installed, the latch head 731 is aligned with the latch hole 741, and the latch head 731 extends into the latch hole 741 to limit the horizontal movement of the power box 40 relative to the equipment box 20.

[0065] In this example, if Figure 6 and Fig.11 As shown, the device box 20 includes a device power supply aviation socket 21, and the power box 40 also includes a battery power supply aviation socket 41. The device power supply aviation socket 21 and the battery power supply aviation socket 41 are connected by wires so that the battery in the power box 40 can power the device in the device box 20.
