[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] like Figure 1 , Figure 4 , Fig.13 ,and Fig.18 As shown, a mining switch described in the present invention includes a protective shell 1, a switch body 7 is provided on the inner side of the protective shell 1, a connecting structure 2 is provided on the side of the protective shell 1, an exhaust structure 8 is connected between the connecting structure 2 and the protective shell 1, a fixing structure 3 is connected between the protective shell 1 and the switch body 7, a sealing structure 4 is provided on the fixing structure 3, a supporting structure 5 is provided on the bottom side of the protective shell 1, and a wire management structure 6 is provided on the supporting structure 5.

[0043] Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12As shown, the connection structure 2 includes a first connection groove 201, the top side of the protective shell 1 is provided with a first connection groove 201, the bottom side of the protective shell 1 is fixedly connected with an insert block 203, the insert block 203 is a hollow structure, the insert block 203 is an "L"-shaped structure, the protective shell 1 is slidably connected with a pushing block 205 on the inner side of the first connection groove 201, the end of the pushing block 205 is a slope structure, a first spring 206 is fixedly connected between the pushing block 205 and the protective shell 1, a sealing plate 204 is rotatably connected to the inner side of the protective shell 1, the side of the sealing plate 204 is in conflict with the protective shell 1, and a first torsion spring 206 is fixedly connected between the sealing plate 204 and the protective shell 1 9. The side of the protective shell 1 is rotatably connected with a locking rod 208, and the middle cross-section of the locking rod 208 is a semicircular structure. Two positioning grooves 207 are provided on the bottom side of the pushing block 205. The locking rod 208 conflicts with the pushing block 205 through the positioning grooves 207. The end of the locking rod 208 is fixedly connected with a positioning rod 202. The positioning rod 202 is rotatably connected to the protective shell 1. A ratchet groove 212 is provided on the side of the positioning rod 202. A ratchet block 210 is slidably connected to the inner side of the protective shell 1. A second spring 211 is fixedly connected between the ratchet block 210 and the protective shell 1, and the end of the ratchet block 210 is meshed with the positioning rod 202 through the ratchet groove 212;

[0044] The switch body 7 is installed on the inner side of the protective shell 1. The protective shell 1 can provide a protective effect for the switch body 7. At the same time, in order to separate the moist air and dust from the outside, a sealing plate 204 is provided in the first connection groove 201 on the top side of the protective shell 1. The sealing plate 204 will close the first connection groove 201 under the action of the first torsion spring 209. At the same time, when multiple switches need to be stacked, after the switch body 7 is placed in the protective shell 1, the protective shells 1 can be connected through the first connection groove 201 and the plug block 203. The plug block 203 is The "L"-shaped structure has an "L"-shaped structure. When the plug block 203 is inserted into the first connecting groove 201, the plug block 203 pushes the sealing plate 204 away and pushes the pushing block 205 back. When the plug block 203 completely slides into the first connecting groove 201, the plug block 203 slides a short distance laterally in the first connecting groove 201 under the push of the pushing block 205. At this time, the plug block 203 is fixed. In order to improve the fixing effect, the user can rotate the positioning rod 202 on the side of the protective shell 1 at this time, so that the locking rod 208 at the end of the positioning rod 202 is rotated to pass through the pushing block 20 The positioning groove 207 on the side conflicts with the pushing block 205, thereby preventing the pushing block 205 from returning to its position. At this time, the connection between the two protective shells 1 can be completed, wherein the positioning rod 202 can only be rotated in one direction through the meshing effect between the side ratchet block 210 and the ratchet groove 212, which is convenient for limiting the rotation position of the positioning rod 202 and can also prevent the locking rod 208 from being automatically released under the push of the pushing block 205. When the two protective shells 1 that have been connected need to be released, the positioning rod 202 needs to be rotated first so that the middle part of the locking rod 208 is aligned with the pushing block 205. 205 no longer conflicts, at this time the user needs to slide the two protective shells 1 relatively so that the end of the insert block 203 pushes the pushing block 205 to completely retract, and then rotate the positioning rod 202 again so that the locking rod 208 conflicts with another positioning groove 207 on the bottom side of the pushing block 205, thereby preventing the pushing block 205 from extending out, and the two protective shells 1 can be separated at this time. At the same time, due to the retraction of the pushing block 205, the sealing plate 204 can automatically seal the first connecting groove 201 under the traction of the first torsion spring 209, thereby ensuring the sealing effect inside the entire device.

[0045] Specifically, Figure 4 , Figure 5 , Figure 7 , Fig.11 , Fig.14As shown, the exhaust structure 8 includes an exhaust port 805, an exhaust port 805 is opened on the side of the protective shell 1, the exhaust port 805 is fixedly connected to the side of the protective shell 1, a plurality of exhaust fans 803 are installed on the inner side of the protective shell 1, a mesh plate 804 is fixedly connected to the end of the protective shell 1, a closing plate 801 is slidably connected to the inner side of the protective shell 1, the middle part of the closing plate 801 is slidably connected to the protective shell 1 through the exhaust port 805, a sixth spring 806 is fixedly connected between the closing plate 801 and the protective shell 1, and push blocks 802 are fixedly connected to both ends of the closing plate 801;

[0046] Since the protective shell 1 fully wraps the switch body 7, in order to provide a sufficient heat dissipation effect for the switch body 7, an exhaust fan 803 and a mesh plate 804 are arranged on the side of the protective shell 1, and an exhaust port 805 is opened on the inner side of the protective shell 1 of the exhaust fan 803. The exhaust port 805 is in an open state in a natural state. After the exhaust fan 803 is connected to the power supply, the air inside the protective shell 1 can be discharged by rotating the exhaust fan 803, and the heat dissipation effect is achieved through the flow of air. On the other hand, when multiple protective shells 1 are stacked, the plug under the protective shell 1 on the top side 203 will be fixed in the first connecting groove 201 of the bottom protective shell 1. At this time, the end of the plug 203 will push the closing plate 801 through the push block 802 at the end of the closing plate 801 to close the exhaust port 805 on the inner side of the bottom protective shell 1. In this way, when multiple protective shells 1 are stacked, only the exhaust port 805 at the end of the topmost protective shell 1 is in a closed state. When the exhaust fan 803 rotates, the airflow will flow from the middle part of the plug 203 of the bottommost protective shell 1 to the top side, thereby achieving the effect of heat dissipation for the switch body 7 inside all protective shells 1.

[0047] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.12 , Fig.13 , Fig.14 , Fig.15As shown, the fixed structure 3 includes a heat dissipation fin 303, and the heat dissipation fin 303 is fixedly connected to both sides of the switch body 7, and a guide groove 304 is provided on the side of the heat dissipation fin 303. A positioning plate 305 is slidably connected to the inner side of the protective shell 1, and a third spring 306 is fixedly connected between the positioning plate 305 and the protective shell 1. The positioning plate 305 is slidably connected to the heat dissipation fin 303 through the guide groove 304. A side cover 301 is slidably connected to the side of the protective shell 1, and a sealing gasket is fixedly connected to the inner side of the side cover 301. 307, the sealing gasket 307 is in conflict with the switch body 7, the side of the protective shell 1 is slidably connected with a release rod 302, a fourth spring 309 is fixedly connected between the release rod 302 and the protective shell 1, the end of the release rod 302 is a slope structure, a slot 310 is provided on the side cover 301, the end of the release rod 302 is engaged with the side cover 301 through the slot 310, and the other side of the protective shell 1 is provided with a spring piece 308, and the spring piece 308 is engaged with the side cover 301 through the slot 310 on the other side of the side cover 301;

[0048] In order to increase the heat dissipation area of ​​the switch, a heat dissipation fin 303 is provided on the side of the switch. The air flowing from bottom to top will pass through the heat dissipation fin 303 to dissipate heat for the switch. The switch body 7 is fixed by the guide groove 304 on the side of the heat dissipation fin 303 and the positioning plate 305 on the inner side of the protective shell 1, ensuring that there is sufficient space between the switch body 7 and the inner side of the protective shell 1 for heat dissipation. A third spring 306 is connected between the positioning plate 305 and the protective shell 1, and both sides of the positioning plate 305 are inclined structures, which is convenient for placing the switch body 7 into the inner side of the protective shell 1. At the same time, a detachable side cover 301 is provided for the interface panel on the side of the switch body 7. One side of the side cover 301 is positioned by a spring 308, and the other side is fixed by the engagement between the release rod 302 and the card slot 310. When the side cover 301 is installed, the sealing gasket 307 on the inner side of the side cover 301 will seal the outer side of the interface on the switch body 7, so that the interface of the switch body 7 is exposed, which is convenient for normal cable connection.

[0049] Specifically, Figure 1 , Fig.13 , Fig.15As shown, the sealing structure 4 includes a threading hole 405, and a plurality of threading holes 405 are provided on the side cover 301. A plurality of shielding plates 401 are rotatably connected to the side of the side cover 301. A second torsion spring 403 is fixedly connected between the shielding plate 401 and the side cover 301. The side of the shielding plate 401 is in conflict with the side cover 301. An opening rod 402 is rotatably connected to the inner side of the side cover 301. The end of the shielding plate 401 is rotatably connected to the opening rod 402. A limiting groove 404 is provided on the inner side of the shielding plate 401. The opening rod 402 is rotatably connected to the shielding plate 401 through the limiting groove 404.

[0050] During the use of the switch, some of its interfaces may be unused. In order to improve the sealing performance of the protective shell 1, a threading hole 405 corresponding to the interface position on the switch body 7 is opened on the side of the protective shell 1, and the connecting cable can be connected to the interface on the switch body 7 through the threading hole 405. At the same time, in order to seal and protect the interface, a shielding plate 401 is provided on one side of the threading hole 405. The shielding plate 401 will automatically block the threading hole 405 under the action of the second torsion spring 403 to provide a better sealing effect for the inner side of the protective shell 1. When the corresponding interface needs to be used, it is only necessary to rotate the shielding plate 401. At the same time, all the shielding plates 401 set on the same side are rotatably connected to the opening rod 402. Through the limiting groove 404 opened inside the shielding plate 401, the user can open all the closed plates on the same side at the same time by rotating the opening rod 402, so as to facilitate the viewing and inspection of the interface.

[0051] Specifically, Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig.11 , Fig.12 , Fig.16 , Fig.17 , Fig.18 As shown, the support structure 5 includes a base 501, the bottom side of the protective shell 1 is slidably connected to the base 501, an exhaust pipe 504 is opened on the inner side of the base 501, and the end of the exhaust pipe 504 is connected to the middle part of the plug block 203, and a plurality of support columns 503 are slidably connected to the bottom side of the base 501, and an adjusting rod 502 is threadedly connected to the inner side of the support column 503, and the adjusting rod 502 is rotatably connected to the base 501;

[0052] When the switch is installed in combination, a base 501 needs to be installed at the bottom. Support columns 503 with adjustable support heights are provided at the four corners of the base 501. The extension height of the support columns 503 can be changed by rotating the corresponding adjustment rods 502 to adapt to different fixed positions. At the same time, an exhaust pipe 504 is provided on the inner side of the base 501. When the plug-in blocks 203 of the protective shell 1 are placed on both sides of the base 501, the ends of the exhaust pipe 504 will be connected to the inner side of the protective shell 1, so that the user can introduce relatively dry and clean air or even refrigerant gas through the input end of the exhaust pipe 504 to cool the switch, thereby avoiding contact between the internal components of the switch and the humid air in the mine, thereby affecting the service life of the equipment.

[0053] Specifically, Figure 1 , Figure 5 , Figure 7 , Fig.14 , Fig.18 As shown, the wiring structure 6 includes a wiring board 601, a plurality of wiring boards 601 are provided on the base 501, a second connecting groove 604 is provided on the side of the wiring board 601, the wiring boards 601 are slidably connected through the second connecting groove 604, the wiring boards 601 at the ends are fixedly connected to the base 501, a fixing rod 602 is slidably connected to the top side of the wiring board 601, a fifth spring 603 is fixedly connected between the fixing rod 602 and the wiring board 601, and the end of the fixing rod 602 conflicts with the wiring board 601;

[0054] A plurality of cable management plates 601 are provided on the base 501, and the cable management plates 601 are slidably connected to each other via a second connecting groove 604 on the side, and the first cable management plate 601 on the side is fixedly connected to the base 501. The wires that need to be organized can be slid through the cable management plates 601 by sliding the fixing rod 602 on the side of the cable management plates 601, so as to achieve organization. When multiple cable management plates 601 are needed, only the other cable management plates 601 need to be lifted up, thereby improving the neatness of cable placement.

[0055] When the present invention is in use, first, the switch body 7 is installed on the inner side of the protective shell 1, and the protective shell 1 can provide a protective effect for the switch body 7. At the same time, in order to separate the moist air and dust from the outside, a sealing plate 204 is provided in the first connecting groove 201 located on the top side of the protective shell 1. The sealing plate 204 will close the first connecting groove 201 under the action of the first torsion spring 209. At the same time, when multiple switches need to be stacked, after the switch body 7 is placed in the protective shell 1, the protective shells 1 can be connected through the first connecting groove 201 and the plug-in block 203. The plug-in block 203 is in an "L"-shaped structure. When the plug-in block 203 is inserted into the first connecting groove 201, the plug-in block 203 pushes the sealing plate 204 open. At the same time, the pushing block 205 is pushed back. When the plug block 203 completely slides into the first connecting groove 201, the plug block 203 will slide horizontally for a short distance in the first connecting groove 201 under the push of the pushing block 205. At this time, the plug block 203 is fixed. In order to improve the fixing effect, the user can rotate the positioning rod 202 on the side of the protective shell 1 at this time, so that the locking rod 208 at the end of the positioning rod 202 rotates to the positioning groove 207 on the side of the pushing block 205 and conflicts with the pushing block 205, thereby preventing the pushing block 205 from returning to its position. At this time, the connection between the two protective shells 1 can be completed, wherein the positioning rod 202 can only be rotated in one direction through the meshing effect between the side ratchet block 210 and the ratchet groove 212, which is convenient for limiting. When the two protective shells 1 are connected, the positioning rod 202 needs to be rotated so that the middle part of the locking rod 208 no longer conflicts with the pushing block 205. At this time, the user needs to slide the two protective shells 1 relatively so that the end of the insert block 203 pushes the pushing block 205 to retract completely, and then rotate the positioning rod 202 again so that the locking rod 208 conflicts with another positioning groove 207 on the bottom side of the pushing block 205, thereby preventing the pushing block 205 from extending. At this time, the two protective shells 1 can be separated. At the same time, due to the retraction of the pushing block 205, the sealing plate 204 can be pulled by the first torsion spring 209. The first connection groove 201 is automatically sealed to ensure the sealing effect of the entire internal part of the device. Since the protective shell 1 fully wraps the switch body 7, in order to provide sufficient heat dissipation effect for the switch body 7, an exhaust fan 803 and a mesh plate 804 are arranged on the side of the protective shell 1. At the same time, the inner protective shell 1 of the exhaust fan 803 is provided with an exhaust port 805, and the exhaust port 805 is in an open state in a natural state. After the exhaust fan 803 is connected to the power supply, the air inside the protective shell 1 can be discharged by rotating the exhaust fan 803, and the heat dissipation effect is achieved by the flow of air. On the other hand, when multiple protective shells 1 are stacked, the plug 203 located below the protective shell 1 on the top side will be fixed in the first connection groove 201 of the bottom protective shell 1.At this time, the end of the plug block 203 will push the closing plate 801 to close the exhaust port 805 on the inner side of the bottom protective shell 1 through the push block 802 at the end of the closing plate 801. In this way, when multiple protective shells 1 are stacked, only the exhaust port 805 at the end of the topmost protective shell 1 is in a closed state. When the exhaust fan 803 rotates, the airflow will flow from the middle part of the plug block 203 of the bottommost protective shell 1 to the top side, thereby achieving the effect of heat dissipation for the switch body 7 inside all protective shells 1. In order to increase the heat dissipation area of ​​the switch, a heat dissipation fin 303 is provided on the side of the switch. The air flowing from bottom to top will pass through the heat dissipation fin 303 to dissipate heat for the switch. The switch body 7 passes through the side of the heat dissipation fin 303 The switch body 7 is fixed with the guide groove 304 and the positioning plate 305 on the inner side of the protective shell 1, ensuring that there is sufficient space between the switch body 7 and the inner side of the protective shell 1 for heat dissipation. A third spring 306 is connected between the positioning plate 305 and the protective shell 1, and the two sides of the positioning plate 305 are inclined structures, which is convenient for placing the switch body 7 into the inner side of the protective shell 1. At the same time, a detachable side cover 301 is provided for the interface panel on the side of the switch body 7. One side of the side cover 301 is positioned by a spring piece 308, and the other side is fixed by the engagement between the release rod 302 and the card slot 310. When the side cover 301 is installed, the sealing gasket 307 on the inner side of the side cover 301 will seal the outer side of the interface on the switch body 7, so that the switch body 7 can be easily connected to the protective shell 1. The interface of the switch body 7 is exposed to facilitate normal cable connection. During the use of the switch, its interface may be unused. In order to improve the sealing performance of the protective shell 1, a threading hole 405 corresponding to the interface position on the switch body 7 is opened on the side of the protective shell 1. The connecting cable can be connected to the interface on the switch body 7 through the threading hole 405. At the same time, in order to seal the interface, a shielding plate 401 is provided on one side of the threading hole 405. The shielding plate 401 will automatically block the threading hole 405 under the action of the second torsion spring 403 to provide a better sealing effect for the inner side of the protective shell 1. When the corresponding interface needs to be used, it is only necessary to rotate the shielding plate 401. At the same time, all shielding plates set on the same side The plates 401 are all rotatably connected to the opening rod 402. Through the limiting groove 404 provided inside the shielding plate 401, the user can simultaneously open all the closed plates on the same side by rotating the opening rod 402, so as to facilitate viewing and inspection of the interface. When the switch is installed in a modular manner, the base 501 needs to be installed at the bottom. The four corners of the base 501 are provided with support columns 503 with adjustable support heights. By rotating the corresponding adjustment rods 502, the extension height of the support columns 503 can be changed to adapt to different fixed positions. At the same time, an exhaust pipe 504 is provided on the inner side of the base 501. When the plug blocks 203 of the protective shell 1 are placed on both sides of the base 501, the ends of the exhaust pipe 504 will be connected to the inner side of the protective shell 1.The user can cool the switch by introducing relatively dry and clean air or even refrigerant gas through the input end of the exhaust pipe 504, so as to avoid the internal components of the switch from contacting the humid air in the mine, thereby affecting the service life of the equipment. A plurality of cable management boards 601 are arranged on the base 501, and the cable management boards 601 are slidably connected through the second connecting grooves 604 on the side, and the first cable management board 601 on the side is fixedly connected to the base 501. The wires that need to be organized can be passed through the cable management board 601 by sliding the fixing rod 602 on the side of the cable management board 601, so as to achieve organization. When multiple cable management boards 601 are needed, only other cable management boards 601 need to be lifted, so as to improve the neatness of cable placement.
