Description

Technical Field

[0001] The present invention belongs to the technical field of communication equipment, and in particular relates to a security device for communication equipment in a railway transportation system. Background Art

[0002] In modern railway transportation systems, communication equipment is a key link to ensure safe train operation and dispatching efficiency. These devices include switches, routers, servers and other network devices, which are usually installed in communication cabinets along the railway. However, during heavy rains, these communication devices often face the risk of being flooded, resulting in equipment damage and communication interruption, which in turn affects the normal operation of the entire railway transportation system.

[0003] Communication equipment generates a lot of heat during operation. Existing communication cabinets need to reserve air inlet / outlet holes to solve the heat dissipation problem. However, due to the existence of air inlet / outlet holes and inspection doors, when the base station is submerged due to heavy rain or flooding, water will enter the communication cabinet through the air inlet / outlet holes and inspection doors. When the liquid level reaches a certain height, the network equipment in the communication cabinet is prone to water intrusion. Water intrusion will not only cause short circuits in communication equipment and aging of components, but may also cause damage to communication equipment, posing a serious threat to the safety of railway transportation. At the same time, replacing new communication equipment will also greatly increase the time and cost of emergency repairs in the railway transportation system.

[0004] Based on the above problems, this application document proposes a security device for railway transportation system communication equipment to solve the water intrusion problem faced by railway transportation system communication equipment during heavy rain or flood. Summary of the invention

[0055] Please refer to the attached Figures 1 to 5 As shown in the figure, it is the first embodiment of the present invention, which provides a security device for communication equipment of a railway transportation system, including a cabinet 100, wherein a heat dissipation cavity 101 and a communication cavity 102 are sequentially provided inside the cabinet 100 from the upper end to the lower end, an integrated circuit board (not shown in the figure) is fixed inside the heat dissipation cavity 101, a plurality of beams 103 are fixed at both ends of the communication cavity 102, and the plurality of beams 103 are located at both ends of the lower end of the cabinet 100, a liquid level sensor 104 is fixed at the lower end of the communication cavity 102, and the liquid level sensor 104 and the integrated circuit board are electrically connected through a wire, and a cable access port 105 and a security cover are provided on one side of the cabinet 100. The cabinet 100 includes a protective shell 106, an inspection door 107 is rotatably connected to the other side of the cabinet 100, and the inspection door 107 is adapted to the communication cavity 102, a plurality of cooling fans 108 are installed inside the communication cavity 102, and the cooling fans 108 are electrically connected to the integrated circuit board through wires, a base 110 is installed at the lower end of the cabinet 100, and the base 110 is fixedly connected to the base, a plurality of water inlet grooves 111 are opened on the side wall of the base 110, and an avoidance hole 112 is opened at the upper end of the base 110, and the avoidance hole 112 and the liquid level sensor 104 are adapted in a clearance fit manner, and the sensing end of the liquid level sensor 104 extends to the inside of the base 110 through the avoidance hole 112, and also includes:

[0056] Two lifting parts 200, the two lifting parts 200 are respectively assembled at two ends of the cabinet 100;

[0057] Two cleaning parts 300, the cleaning parts 300 are assembled between the lifting part 200 and the cabinet 100, and the cleaning parts 300 and the lifting part 200 are adapted to each other;

[0058] A reel 400, which is mounted on one side of the cabinet 100, and has a cable wound inside the reel 400;

[0059] A plurality of tensioning parts 500 are assembled in an S shape at one end of the cabinet 100, and the tensioning parts 500 and the cable, the tensioning parts 500 and the protective shell 106, the winding part 400 and the protective shell 106, and the cable access port 105 and the protective shell 106 are all adapted to each other;

[0060] Among them, the monitoring threshold is set through the integrated circuit board. When the base is submerged in water and the distance between the liquid surface and the liquid level sensor 104 is less than or equal to the monitoring threshold, the lifting part 200 operates and drives the cabinet 100 to move away from the liquid surface.

[0061] It should be noted that, in this embodiment, the base refers to a raised platform built along the railway in order to keep the installed communication cabinet and communication equipment in a horizontal state. Pipelines are pre-buried inside the base, and communication cables are laid inside the pipelines. The base can be built in any of the following ways: concrete pouring, brick masonry or other construction methods. The base 110 and the base are fixedly connected by an expansion screw assembly.

[0062] Furthermore, in this embodiment, when laying communication cables, the cables pass through the pre-buried pipes inside the base station, pass through the winding section 400 and are wound by the winding section 400, and then enter the cabinet 100 through the cable access port 105 to be connected to the communication equipment.

[0063] In this embodiment, when a rainstorm or flood causes the water level along the railway to rise and the base is submerged, water enters the base 110 through the water inlet trough 111, and the water level is monitored by the liquid level sensor 104. When the water level inside the base 110 reaches the monitoring threshold, the liquid level sensor 104 transmits a signal to the integrated circuit board, which drives the lifting part 200 to operate, and drives the cabinet 100 and the communication equipment inside it to move upward through the lifting part 200 to prevent water from entering the cabinet 100. At the same time, the cabinet 100 drives the winding part 40 0 operation, stretching the wound cable to prevent the communication equipment and the cable from being separated due to the rise of the cabinet 100. When the water level gradually decreases, the water level is monitored by the liquid level sensor 104, and the cabinet 100 is driven to move downward for reset by the lifting part 200. At the same time, the reeling part 400 reels the stretched cable. The above-mentioned scheme can effectively prevent water from entering the cabinet 100 during heavy rain or flood, causing water intrusion to the communication equipment, thereby ensuring the safety of the railway transportation system and avoiding damage to the communication equipment.

[0064] Here, when the water level does not submerge the base 110, the water level inside the base 110 is monitored by the liquid level sensor 104, which can also avoid or reduce the impact of external environmental factors on the water level height inside the base 110 (such as liquid level fluctuation).

[0065] Next, please refer to Figure 6 to Figure 7 The lifting part 200 includes a motor 201, a worm 202, a threaded rod 203, a worm wheel 204, a card plate 205, a guide sleeve 206 and a guide shaft 207. The motor 201 is fixed inside the heat dissipation cavity 101, and the motor 201 and the integrated circuit board are electrically connected through a wire. The worm 202 is fixed to the output end of the motor 201, and the worm 202 and the cabinet 100 are rotatably connected. The threaded rod 203 is rotatably connected to the inside of the cabinet 100, and the upper end and the lower end of the threaded rod 203 extend to the heat dissipation cavity 101 and the communication cavity 101, respectively. 2, and the lower end of the outer side of the threaded rod 203 is provided with an external thread section, the worm wheel 204 is fixed to the upper end of the outer side of the threaded rod 203 and is located inside the heat dissipation cavity 101, and the worm wheel 204 and the worm 202 are meshed and connected, the clamping plate 205 is fixed to the outer side of the cross beam 103, the guide sleeve 206 is fixed to the inside of the clamping plate 205, the guide shaft 207 is fixed to the inside of the base 110, the guide shaft 207 is provided with an internal thread hole, and the guide shaft 207 and the threaded rod 203 are connected by the matching threads of the external thread section and the internal thread hole.

[0066] It should be noted that a flange seat 208 and a flange plate 209 are fixed inside the communication cavity 102 , and the worm 202 and the flange seat 208 as well as the threaded rod 203 and the flange plate 209 are rotatably connected via ball bearings.

[0067] In this embodiment, when a rainstorm or flood strikes, when the liquid level sensor 104 detects that the liquid level has reached the monitoring threshold, the motor 201 is started through the integrated circuit board, and the motor 201 and the worm 202 are fixedly connected, so that the motor 201 drives the worm 202 to rotate, and the worm 202 and the worm wheel 204 are meshed and connected, so that the worm 202 drives the worm wheel 204 to rotate, and the worm wheel 204 and the threaded rod 203 are fixedly connected, so that the worm wheel 204 drives the threaded rod 203 to rotate, and because the threaded rod 203 and the guide shaft 207 are threadedly connected and the guide shaft 207 and the base 110 are fixedly connected, the threaded rod 203 rotates relative to the guide shaft 207 and moves upward, and the threaded rod 203 and the cabinet body are connected. The rotating connection of 100 allows the threaded rod 203 to drive the cabinet 100 to move upward, and then drives the communication equipment inside it to move upward through the cabinet 100, thereby preventing water from entering the cabinet 100. At the same time, during the vertical movement of the cabinet 100, the cabinet 100 drives the cross beam 103 to move synchronously through the fixed connection between the cabinet 100 and the cross beam 103. Through the fixed connection between the cross beam 103 and the card plate 205 and the fixed connection between the card plate 205 and the guide sleeve 206, the cabinet 100 drives the card plate 205 and the guide sleeve 206 to move synchronously. Through the cooperation of the guide sleeve 206 and the guide shaft 207, multi-point support and guidance can be formed for the cabinet 100, thereby ensuring the stability of the cabinet 100 during movement.

[0068] Here, when the worm 202 and the worm wheel 204 are used together, they also have a self-locking property. After the height of the cabinet 100 is moved to a suitable position, the self-locking property of the worm 202 and the worm wheel 204 when used together can prevent the position of the cabinet 100 from being affected by external environmental factors and changing.

[0069] In a preferred embodiment, the lower end of the guide shaft 207 passes through the base 110 and extends to the inside of the abutment. The guide shaft 207 and the abutment are fixedly connected. A plurality of feet are provided at the lower end of the outer side of the guide shaft 207 and located inside the abutment.

[0070] It should be noted that, during the process of constructing the base, the guide shaft 207 needs to be placed in the base.

[0071] In this embodiment, the arrangement of the palm and foot facilitates maintaining a stable connection between the base and the guide shaft 207 , and at the same time facilitates the guide shaft 207 to guide the guide sleeve 206 and the cabinet 100 .

[0072] Next, please refer to Figure 5 as well as Figures 8 to 10As shown, guide surfaces 113 are inclined at both ends of the top of the base 110, and the guide surfaces 113 are matched with the guide shaft 207. The cleaning part 300 includes a dust removal block 301, which is fixed at the lower end of the communication cavity 102, and the dust removal block 301 is slidably connected to the guide shaft 207. A separation edge 302 is provided at the lower end of the dust removal block 301 and located at the lower end of the cabinet 100. The separation edge 302 is located at the lower end of the cabinet 100, and the separation edge 302 is matched with the guide shaft 207.

[0073] In this embodiment, after a rainstorm or flood occurs and the water level submerges the base 110, the mud and sand in the water will be retained on the surface of the guide shaft 207 during the process of water receding. During the process of the cabinet 100 driving the guide sleeve 206 to return to its original position, the guide sleeve 206 slides on the outside of the guide shaft 207. The mud and sand retained on the surface of the guide shaft 207 will cause the guide sleeve 206 and the guide shaft 207 to wear more, thereby causing the inner wall of the guide sleeve 206 and the outer side of the guide shaft 207 to wear, increasing the matching clearance between the guide sleeve 206 and the guide shaft 207, and affecting the guiding effect of the guide shaft 207 on the guide sleeve 206. In order to avoid the above problems, by fixing the dust removal block 301 at the lower end inside the cabinet 100, the cabinet 100 will drive the dust removal block 301 to move synchronously during the resetting process, and clean and remove the mud and sand on the outside of the guide shaft 207 through the separation edge 302, so as to avoid wear between the guide sleeve 206 and the guide shaft 207 and reduce the guiding effect of the guide shaft 207. At the same time, the mud and sand cleaned by the separation edge 302 falls onto the surface of the guide surface 113, so that the mud and sand can fall along the surface of the guide surface 113 to the outside of the base 110, so as to avoid the accumulation of mud and sand at the upper end of the base 110.

[0074] Please refer again Figures 8 to 10 As shown, an air cavity 310 is fixed to the upper end of the dust removal block 301, and a plurality of guide rods 311 are fixed between the dust removal block 301 and the air cavity 310. A piston plate 312 is slidably connected to the outside of the plurality of guide rods 311 and located inside the air cavity 310, and the air cavity 310 and the piston plate 312 are slidably connected. A coil spring 313 is installed between the piston plate 312 and the air cavity 310 and located at the upper end of the piston plate 312. A plurality of piston rods 314 are fixed to the lower end of the piston plate 312. The lower ends of the piston rods 314 extend through the dust removal block 301. To the lower end of the cabinet 100, the piston rod 314 and the dust removal block 301 are slidably connected, the piston rod 314 and the guide surface 113 are adapted to each other, an air inlet check valve 315 and an air outlet check valve 316 are fixed to the upper end of the air cavity 310, a plurality of nozzles 317 are fixed inside the dust removal block 301, an input end of the nozzle 317 and the air outlet check valve 316 are connected through a pipeline, and an output end of the nozzle 317 passes through the separation edge 302 and extends to the lower end of the cabinet 100, and a plurality of pressure regulating holes 318 are opened at the lower end of the outer side of the air cavity 310.

[0075] It should be noted that, in the initial state, the piston rod 314 and the base 110 are in contact, and the base 110 squeezes the coil spring 313 through the piston rod 314, and the coil spring 313 is always in a compressed state.

[0076] Here, the flow direction of the gas inside the air inlet check valve 315 is from the outside of the air cavity 310 to the inside of the air cavity 310 , and the flow direction of the gas inside the air outlet check valve 316 is from the inside of the air cavity 310 to the outside of the air cavity 310 .

[0077] In this embodiment, when a rainstorm or flood strikes, the water level is monitored by the liquid level sensor 104. When the water level reaches the monitoring threshold, the motor 201 operates and drives the cabinet 100 to move upward, so that the cabinet 100 and the base 110 move away from each other. During this process, the piston rod 314 moves downward relative to the cabinet 100 and the air cavity 310, and the gas outside the air cavity 310 flows into the air cavity 310 through the air inlet check valve 315. When the water recedes and the water level gradually decreases, the motor 201 drives the cabinet 100 to move toward the base 110 and reset. When the piston rod 314 contacts the guide surface 113, the cabinet 100 moves downward. , the piston rod 314 is driven to move upward relative to the air cavity 310 through the guide surface 113, and the piston rod 314 drives the piston plate 312 to move upward relative to the air cavity 310 through the fixed connection between the piston rod 314 and the piston plate 312, and the gas at the upper end of the air cavity 310 is squeezed by the piston plate 312, so that the gas at the upper end of the air cavity 310 flows out through the gas outlet check valve 316, and is blown to the top of the base 110 through the pipeline and the nozzle 317 in turn, so as to blow away the mud and sand deposited on the top of the base 110 and the surface of the guide surface 113, and clean the top of the base 110 and the surface of the guide surface 113.

[0078] In a specific embodiment, by adjusting the direction of the output end of the nozzle 317, the purpose of cleaning the mud and sand in different directions can be achieved. The number of nozzles 317 and the direction of the output end of the nozzle 317 can be adjusted according to actual use requirements, which does not constitute a specific limitation here.

[0079] Please refer again Fig.11 and Fig.12As shown, the winding portion 400 includes a winding shell 401, a winding shaft 402, a winding roller 403 and a spring spring 404. The winding shell 401 is fixed to one side of the cabinet 100, the winding shaft 402 is rotatably connected to the inside of the winding shell 401, the winding roller 403 is fixed to the outside of the winding shaft 402, and the winding shell 401 and the winding roller 403 are rotatably connected, the spring spring 404 is assembled between the winding shell 401 and the winding shaft 402, and the winding shaft 402 and the winding roller 403 are both provided with a cable through hole 405, wherein, in the initial state, the cable passes through the cable through hole 405 and is wound around the inside of the winding roller 403.

[0080] In this embodiment, when a rainstorm or flood strikes, the motor 201 drives the cabinet 100 to move upward, and through the fixed connection between the cabinet 100 and the winding shell 401, the cabinet 100 drives the winding shell 401 to move upward synchronously. At the same time, part of the cable pre-buried in the base will pull the cable wound on the winding roller 403, causing the winding roller 403 to rotate, thereby releasing the cable wound on the winding roller 403, so that the cable wound on the winding roller 403 is changed from a wound state to an extended state, thereby avoiding the cabinet During the rising process of the cabinet 100, the cable is pulled and the cable and the communication equipment are separated. At the same time, the winding roller 403 is fixedly connected with the winding shaft 402, so that the winding roller 403 drives the winding shaft 402 to rotate, and the winding shaft 402 compresses the clockwork spring 404. When the water level gradually decreases, the motor 201 drives the cabinet 100 to reset, and the compressed clockwork spring 404 drives the winding shaft 402 and the winding roller 403 to rotate and reset, and the cable in the extended state is rewound by the winding roller 403.

[0081] Please refer again Figure 4 , Fig.13 as well as Fig.14 As shown, the tensioning part 500 includes a tensioning shell 501, a guide block 502, a T-shaped tensioning rod 503 and a tensioning spring 504. The tensioning shell 501 is fixed to one side of the cabinet 100, the guide block 502 is slidably connected to the inside of the tensioning shell 501, the T-shaped tensioning rod 503 is fixed to one side of the guide block 502, and the T-shaped tensioning rod 503 and the tensioning shell 501 are slidably connected. The tensioning spring 504 is assembled between the tensioning shell 501 and the guide block 502. In the initial state, the tensioning spring 504 is in a stretched state.

[0082] It should be noted that the cable winding inside the winding roller 403 can be seen from the top view. Fig.12As shown, before the cable passing through the base station enters the cable access port 105, it needs to pass through the cable via 405 and be wound around the winding roller 403. In order to better describe the working process of the device, the cable portion between the cable via 405 and the cable access port 105 is recorded as the upper cable section, and the cable portion between the cable via 405 and the base station is recorded as the lower cable section.

[0083] Furthermore, in the initial state, the upper section of the cable and the lower section of the cable are both wound inside the winding roller 403, wherein, when the cabinet 100 moves upward, the distance between the cabinet 100 and the base gradually increases, and the lower section of the cable changes from a wound state to a stretched state. Since the distance between the winding roller 403 and the cable access port 105 remains unchanged, the upper section of the cable changes from a wound state to a loose state. Moreover, in the initial state, the upper end cable is in a wound state under the action of the clockwork spring 404, and the wound upper section of the cable drives the T-shaped tensioning rod 503 to move and stretch the tensioning spring 504, so that the tensioning spring 504 is in a stretched state.

[0084] It should be noted that the number of tensioning parts 500 can be adjusted according to actual usage requirements. In the present embodiment, the number of tensioning parts 500 is three, which does not constitute a specific limitation.

[0085] In this embodiment, when the cabinet 100 rises, since the distance between the winding roller 403 and the cable access port 105 remains unchanged, the upper section of the cable changes from a wound state to a loose state, and since the tensioning spring 504 is in a stretched state, the tensioning spring 504 drives the guide block 502 to reset, and the guide block 502 and the T-shaped tensioning rod 503 are fixedly connected, so that the guide block 502 drives the T-shaped tensioning rod 503 to move, and then through the cooperation of multiple T-shaped tensioning rods 503, the loose cable is tensioned, so that the upper section of the cable passes through the outside of multiple T-shaped tensioning rods 503 in an S-shaped shape, and through the cooperation of multiple T-shaped tensioning rods 503, the upper section of the cable is prevented from hanging down inside the protective shell 106, and the hanging upper section of the cable is prevented from being hooked (that is, the upper section of the cable is hooked by other components) during the resetting process of the cabinet 100, resulting in the upper section of the cable being unable to be reeled up.

[0086] The working principle of the present invention is:

[0087] During a rainstorm or flood, water enters the base 110 through the water inlet trough 111, and the water level is monitored by the liquid level sensor 104. When the water level reaches the monitoring threshold, the motor 201 drives the threaded rod 203 to rotate, so that the threaded rod 203 drives the cabinet 100 to move upward. At the same time, the lower section of the cable wound inside the winding roller 403 changes from a wound state to a stretched state, and the upper section of the cable is tensioned through the cooperation of multiple T-shaped tensioning rods 503 to prevent the upper section of the cable from sagging, and the communication equipment inside the cabinet 100 is driven to move upward to prevent water from entering the cabinet 100, causing the communication equipment to be damaged. When water intrusion occurs, when the water recedes and the water level gradually decreases, the cabinet 100 is driven downward to reset by rotating the motor 201. When the piston rod 314 contacts the base 110, the base 110 drives the piston rod 314 and the piston plate 312 to move, and the gas at the upper end of the air cavity 310 is squeezed, so that the gas at the upper end of the air cavity 310 is sprayed toward the surface of the base 110 through the nozzle 317, and the mud and sand deposited on the surface of the base 110 are cleaned. At the same time, the mud and sand retained on the surface of the guide shaft 207 are cleaned through the separation edge 302, thereby improving the guiding effect of the guide shaft 207.

[0088] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified and limited.
