Description

Technical Field

[0001] This invention relates to the field of base station technology, and in particular to an intrinsically safe base station for mining and its usage method. Background Technology

[0002] A base station, or public mobile communication base station, is an interface device for mobile devices to access the internet. It is also a type of radio station. Specifically, it refers to a mine-specific intrinsically safe base station used in areas with extremely poor signal coverage, such as mines. Intrinsically safe base stations are mainly suitable for wireless signal coverage within coal mine areas and underground tunnels, and are core network equipment for building wireless network coverage and establishing mine communication systems.

[0003] Currently, the intrinsically safe base stations used in mining applications typically have multiple sets of evenly distributed straight-through joints, feeder adapters, and aviation connectors. When some of these connectors are not in use, the unused connectors are not shielded from wiring, and dust and moisture from the mine directly adhere to these connectors, leading to moisture damage and poor contact. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the current intrinsically safe base station for mining and its usage method, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide an intrinsically safe base station for mining and its usage method, which is applicable to solving the problem that when some of the connectors are not in use, the unused connectors are not shielded, and dust and moisture from the mine directly adhere to these connectors, leading to moisture and poor contact of these connectors.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intrinsically safe base station for mining, comprising:

[0008] The main base station unit includes an explosion-proof enclosure, a main board installed inside the explosion-proof enclosure, and an optical fiber box. Corresponding straight-through sections and feeder adapters are installed on both sides of the explosion-proof enclosure.

[0009] The joint dustproof unit includes a fixed cover fixedly installed on both sides of an explosion-proof enclosure and an extended cover slidably connected to the fixed cover. The fixed cover and the extended cover are fixedly connected by multiple sets of evenly distributed electric telescopic rods. A drive box is fixedly installed on the side of the extended cover away from the explosion-proof enclosure. A drive motor is fixedly connected to one end of the extended cover. A bidirectional lead screw is fixedly connected to the output shaft of the drive motor. The end of the bidirectional lead screw away from the output shaft of the drive motor is rotatably connected to the inner end wall of the drive box. A symmetrically positioned moving block is threaded onto the bidirectional lead screw. The moving block is slidably connected to the drive box. Each moving block is fixedly connected to a corresponding pull rod. A connecting block is fixedly connected to the side of the pull rod away from the explosion-proof enclosure. Each connecting block is connected to a corresponding telescopic dustproof cloth on the inner side wall of the extended cover.

[0010] As a preferred embodiment of the intrinsically safe base station for mining and its usage method described in this invention, the base station further includes a rapid positioning unit, which includes a mounting base located on the lower side wall of an explosion-proof enclosure. The mounting base is configured as a hollow structure, and an adjusting rod is rotatably connected to one side of the mounting base. Multiple sets of evenly distributed first helical gears are fixedly sleeved on the adjusting rod. Multiple sets of second helical gears meshing with the first helical gears are provided inside the mounting base. Each second helical gear is rotatably connected to the inner side wall of the mounting base through a corresponding threaded rod. A corresponding movable nut is threaded onto the threaded rod. A corresponding connecting lug is fixedly connected to the upper side wall of each movable nut. A corresponding positioning plate is fixedly connected to the connecting lug through a corresponding tensioning rod. Each tensioning rod extends outward through the side wall of the mounting base. Multiple sets of positioning plates abut against the explosion-proof enclosure.

[0011] As a preferred embodiment of the intrinsically safe base station for mining and its usage method described in this invention, each of the positioning covers is fixedly connected to a plurality of uniformly distributed positioning protrusions at the end away from the support rod, and the explosion-proof housing is provided with positioning grooves that match the positioning protrusions.

[0012] As a preferred embodiment of the intrinsically safe base station for mining and its usage method described in this invention, wherein: a corresponding auxiliary support plate is fixedly installed inside the drive box, the bidirectional lead screw passes through the auxiliary support plate, and the bidirectional lead screw is rotatably connected to the auxiliary support plate.

[0013] As a preferred embodiment of the intrinsically safe base station for mining and its usage method described in this invention, the end of the pull rod away from the moving block is equipped with a corresponding guide wheel, and the drive box is provided with a guide groove that matches the guide wheel.

[0014] As a preferred embodiment of the intrinsically safe base station for mining and its usage method described in this invention, the tensioning rod is made of austenitic stainless steel and is U-shaped.

[0015] As a preferred embodiment of the intrinsically safe base station for mining and its usage method described in this invention, a layer of sealing rubber ring of uniform thickness is provided at the connection between the fixed cover and the extended cover, and the depth of the extended cover is one-third to one-half of the depth of the fixed cover.

[0016] A method for using an intrinsically safe base station for mining, the method being applicable to any of the above-mentioned base stations, and the method comprising the following steps:

[0017] S1: Place the explosion-proof enclosure on the side wall of the mounting base, rotate the adjusting rod in the forward direction, and the tensioning rod will drive the positioning plate to clamp the explosion-proof enclosure;

[0018] S2: When wiring is required for the straight section and feeder adapter, control the drive motor to move the pull rod and telescopic dustproof cloth to both sides and open the extension cover;

[0019] S3: After use, control the electric telescopic rod to extend the cover out of the fixed cover, and control the drive motor to pull the pull rod to close the telescopic dustproof cloth, providing dust protection for multiple straight sections and feeder adapters.

[0020] The beneficial effects of this invention are as follows: When the feeder adapter and straight-through joint on the explosion-proof enclosure are not in use, the output shaft of the control drive motor drives the bidirectional lead screw to rotate. The moving block, which is threadedly connected to the bidirectional lead screw, drives the pull rod and the connecting block to move closer to each other. The telescopic dustproof cloth gradually covers the corresponding protruding cover, providing dustproof and moisture-proof protection for the straight-through joint and feeder adapter inside. This effectively solves the defect that moisture or dust enters the straight-through joint and feeder adapter, causing the connector to become damp or have poor contact.

[0021] When installing the base station, rotating the adjusting rod forward causes the first helical gear fixed on it to drive the corresponding threaded rod to rotate through the second helical gear. The movable nut, which is threaded to the threaded rod, then drives the tensioning rod and the positioning plate to simultaneously position and clamp the explosion-proof enclosure. The base station can be installed simply by rotating the adjusting rod in both directions, without having to tighten multiple sets of bolts sequentially, which greatly improves the efficiency of base station installation and disassembly.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0035] Reference Figures 1-7 According to one embodiment of the present invention, an intrinsically safe base station for mining is provided, comprising: a main base station unit 100, a connector dustproof unit 200, and a fast positioning unit 300.

[0036] The main base station unit 100 includes an explosion-proof enclosure 101, a main board 102 installed inside the explosion-proof enclosure 101, and an optical fiber junction box 103. Corresponding straight-through joints 104 and feeder adapters 105 are respectively installed on both sides of the explosion-proof enclosure 101. The main board 102, the optical fiber junction box 103, the straight-through joints 104, and the feeder adapters 105 are inherent components of the base station. The side wall of the explosion-proof enclosure 101 is also provided with multiple sets of plugs, such as aviation plugs. Therefore, the structure of the present invention will not be described in detail.

[0037] The dustproof connector unit 200 includes a fixed cover 201 fixedly installed on both sides of the explosion-proof enclosure 101, and an extension cover 202 slidably connected to the fixed cover 201. A sealing rubber ring of uniform thickness is provided at the connection between the fixed cover 201 and the extension cover 202, and the depth of the extension cover 202 is one-third to one-half the depth of the fixed cover 201. The sealing rubber ring improves the sealing performance of the connection between the extension cover 202 and the fixed cover 201, effectively preventing dust and moisture from entering the wiring of the explosion-proof enclosure 101 through the gap between the two. The extension covers 202 are fixedly connected by multiple sets of evenly distributed electric telescopic rods 203. A drive box 204 is fixedly installed on the side of the extension cover 202 away from the explosion-proof enclosure 101. A drive motor 205 is fixedly connected to one end of the extension cover 202. This drive motor 205 is a servo motor, and its output shaft can rotate both forward and reverse. This is a very mature existing technology, and its working principle will not be described in detail here. A bidirectional lead screw 206 is fixedly connected to the output shaft of the drive motor 205. The end of the bidirectional lead screw 206 away from the output shaft of the drive motor 205 is connected to the drive box 204. The drive box 204 has a fixed auxiliary support plate 207, which is rotatably connected to the end wall. A bidirectional lead screw 206 passes through the auxiliary support plate 207 and is rotatably connected to the auxiliary support plate 207. The auxiliary support plate 207 effectively solves the defect of uneven force and eccentric deformation of the bidirectional lead screw 206. Symmetrically positioned moving blocks 208 are threaded onto the bidirectional lead screw 206. The moving blocks 208 are slidably connected to the drive box 204. Each moving block 208 is fixedly connected to a corresponding pull rod 209, which is located away from the moving block 204. One end of the 8 is equipped with a corresponding guide wheel 210. The drive box 204 has a guide groove that matches the guide wheel 210. Through the setting of the guide wheel 210 and the guide groove, the movement of the pull rod 209 in the extension cover 202 can be guided and limited. The guide wheel 210 is in rolling connection with the inner wall of the extension cover 202, and the friction is small, which makes it easy for the pull rod 209 to pull the telescopic dustproof cloth 212. A connecting block 211 is fixedly connected to the side of the pull rod 209 away from the explosion-proof box 101. Each connecting block 211 is connected to the inner wall of the extension cover 202 with a corresponding telescopic dustproof cloth 212.

[0038] The quick positioning unit 300 includes a mounting base 301 located on the lower side wall of the explosion-proof enclosure 101. The mounting base 301 has a hollow structure, and an adjusting rod 302 is rotatably connected to one side of the mounting base 301. Multiple sets of evenly distributed first helical gears 303 are fixedly sleeved on the adjusting rod 302. Multiple sets of second helical gears 304 meshing with the first helical gears 303 are provided inside the mounting base 301. Each second helical gear 304 is rotatably connected to the inner side wall of the mounting base 301 via a corresponding threaded rod 305. A corresponding movable nut 306 is threaded onto the threaded rod 305. A corresponding connecting ear is fixedly connected to the upper side wall of each movable nut 306. The connecting ear is fixedly connected to a corresponding tensioning rod 307. The corresponding positioning plate 308 and the tensioning rod 307 are made of austenitic stainless steel and are U-shaped. The tensioning rod 307 made of austenitic stainless steel not only has strong corrosion resistance but also meets its own strength requirements. Each tensioning rod 307 extends outward through the side wall of the mounting base 301. Multiple positioning plates 308 abut against the explosion-proof enclosure 101. Each positioning cover has multiple evenly distributed positioning protrusions 309 fixedly connected to the end away from the tensioning rod 307. The explosion-proof enclosure 101 has positioning grooves that match the positioning protrusions 309. The positioning effect of the positioning plate on the explosion-proof enclosure 101 is improved by the cooperation of the positioning protrusions 309 and the positioning grooves.

[0039] A method for using an intrinsically safe base station for mining applications, applicable to any of the above-mentioned base stations, and comprising the following steps:

[0040] S1: Place the explosion-proof enclosure 101 on the upper side wall of the mounting base 301, rotate the adjusting rod 302 in the forward direction, and the tensioning rod 307 will drive the positioning plate 308 to clamp the explosion-proof enclosure 101.

[0041] S2: When wiring is required for the straight section 104 and the feeder adapter 105, control the drive motor 205 to drive the pull rod 209 and the telescopic dustproof cloth 212 to retract to both sides and open the extension cover 202.

[0042] S3: After use, control the electric telescopic rod 203 to drive the extension cover 202 to extend the fixed cover 201, control the drive motor 205 to drive the pull rod 209 to pull the telescopic dustproof cloth 212 to close the extension cover 202, and provide dust protection for multiple straight sections 104 and feeder adapters 105.

[0043] During use, when the feeder adapter 105 and straight section 104 on the explosion-proof enclosure 101 are not in use, the output shaft of the control drive motor 205 drives the bidirectional lead screw 206 to rotate. The moving block 208, which is threadedly connected to the bidirectional lead screw 206, drives the pull rod 209 and the connecting block 211 to move closer to each other. The telescopic dustproof cloth 212 then gradually covers the corresponding protruding cover 202, providing dustproof and moisture-proof protection for the straight section 104 and feeder adapter 105 inside. This effectively solves the defect that moisture or dust enters the straight section 104 and feeder adapter 105, causing the connector to become damp or have poor contact.

[0044] When installing the base station, rotating the adjusting rod 302 in the forward direction causes the first helical gear 303, which is fixedly sleeved on it, to drive the corresponding threaded rod 305 to rotate through the second helical gear 304. The movable nut 306, which is threadedly connected to the threaded rod 305, then drives the tensioning rod 307 and the positioning plate 308 to simultaneously position and clamp the explosion-proof enclosure 101. The base station can be installed simply by rotating the adjusting rod 302 in both directions, without having to tighten multiple sets of bolts in sequence, which greatly improves the efficiency of base station installation and disassembly.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
