[0026] 2. The present invention uses a cooling mechanism. When the water level in the heat pipe drops, the float follows the water level.

[0029] 4. The present invention uses a trigger component. After the water pump completes water replenishment to the heat pipe, the water level in the heat pipe rises. Under the buoyancy of the water in the heat pipe, the float pushes the movable rod to contact the contact switch, compressing the spring. The telescopic end of the electric push rod extends to flip the cover plate downward, shrinking the air flow channel of the air hole, and mainly using water cooling. When the water level in the heat pipe drops, the float moves downward, and the spring continues to extend, so that the movable rod continues to contact the contact switch. When the water level continues to drop, the spring is fully expanded, and the movable rod is disconnected from the contact switch. At this time, the telescopic end of the electric push rod retracts, flips the cover plate upward, and expands the air flow channel of the air hole, ensuring that the video front-end box can still dissipate heat through the air flow channel when the water cooling effect is lost.

[0041] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0042] like Figures 1 to 9 As shown, a monitoring video device applied to a high-speed railway line provided by an embodiment of the present invention includes a camera 1, a video front-end box 2, a monitoring system and a support frame 3 that can be detachably installed in the video front-end box 2, the support frame 3 is fixed to the ground with bolts, the camera 1 and the video front-end box 2 are both fixedly installed on the support frame 3, the camera 1 is electrically connected to the video front-end box 2, the video front-end box 2 is used to monitor the operating status of the camera 1, and the detection system includes a dynamic environment monitoring module, a power supply monitoring module, a data transmission module, a fault location module and a system terminal;

[0043] The dynamic environment monitoring module is used to monitor temperature and humidity, water immersion, tilt angle, vibration, impact and cabinet door status;

[0045] The fault location module is used to diagnose power supply faults, network faults and equipment faults and determine the fault location;

[0046] The data transmission module is connected to the system terminal signal, and the data transmission module is used to transmit the information collected by the system terminal to the control center;

[0047] The dynamic environment monitoring module, the power supply monitoring module and the fault location module are connected to the system terminal signal. The system terminal is used to receive information, organize the information, and then transmit it to the control center through the data transmission module.

[0048] By adopting the above scheme, through the use of the detection system, the components and camera 1 in the video front-end box 1 can be monitored, and the operating status of the monitoring equipment can be grasped in real time. When a fault occurs, the information of the faulty part can be reported in time, which can improve the work efficiency of the maintenance personnel and reduce the working time of the maintenance personnel.

[0049] In this embodiment, a cooling mechanism is installed in the video front-end box 2, and the cooling mechanism is used to cool the video front-end box 2;

[0050] The cooling mechanism includes a water tank 4, a water pump 5, a floating block 6 and a heat pipe 7, wherein the heat pipe 7 is fixedly connected to the inner wall of the video front-end box 2, and the end of the heat pipe 7 away from the water pump 5 passes through the side wall of the video front-end box 2, the water inlet end of the water pump 5 is connected to the water tank 4, and the water outlet end of the water pump 5 is connected to the heat pipe 7, the floating block 6 is slidably installed in the heat pipe 7, and the side of the end of the heat pipe 7 away from the water pump 5 is provided with an evaporation port 13, and a first proximity switch 8 is fixedly installed at the end of the heat pipe 7, and a second proximity switch 9 is fixedly installed on the pipe wall of the heat pipe 7, the first proximity switch 8 and the second proximity switch 9 can both sense the position of the floating block 6, the first proximity switch 8 is used to turn off the water pump 5, and the second proximity switch 9 is used to turn on the water pump 5;

[0051] When the water level in the heat pipe 7 drops, the second proximity switch 9 senses the float 6 and turns on the water pump 5, which then supplies the water in the water tank 4 to the heat pipe 7;

[0052] When the water level in the heat conducting pipe 7 rises, the first proximity switch 8 senses the float 6 and turns off the water pump 5, thereby stopping the water supply.

[0053] By adopting the above scheme, through the use of the cooling mechanism, when the water level in the heat pipe 7 drops, the float 6 follows the water level drop. When the float 6 moves to the position of the second proximity switch 9, the second proximity switch 9 senses the position of the float 6 and turns on the water pump 5. The water pump 5 pumps the water in the water tank 4 into the heat pipe 7.

[0054] After the water level in the heat pipe 7 rises, the water pump 5 is still in the on state. The rising water level drives the float 6 to move upward along the heat pipe 7. When the float 6 moves to the position of the first proximity switch 8, the first proximity switch 8 turns off the water pump 5.

[0055] In this embodiment, a ventilation hole 10 is opened on the side of the video front-end box 2 , a rotating rod 11 is rotatably installed in the ventilation hole 10 , and a cover plate 12 is fixedly connected to the rotating rod 11 .

[0056] By adopting the above scheme, through the use of the air vents 10, an air flow channel can be provided inside the video front-end box 2, the heat inside the video front-end box 2 can be exchanged, and the size of the air flow channel can be limited by the cooperation of the rotating rod 11 and the cover plate 12.

[0057] In this embodiment, a transmission mechanism is connected to the upper part of the floating block 6, and the transmission mechanism is used to pull the rotating rod 11 to rotate; the transmission mechanism includes a gear 14, a rack 15 meshing with the gear 14, a contact switch 16, an electric push rod 17 and a trigger member 18, and the trigger member 18 is installed on the floating block 6, and the trigger member 18 can contact the contact switch 16, and the contact switch 16 is electrically connected to the electric push rod 17, and the telescopic end of the electric push rod 17 is fixedly connected to the rack 15, the gear 14 is fixedly sleeved on the rotating rod 11, and the electric push rod 17 is fixedly installed in the air vent;

[0058] When the telescopic end of the electric push rod 17 is extended, the rack 15 is driven to move upward, thereby rotating the gear 14, driving the rotating rod 11 to rotate, and flipping the cover plate 12 downward;

[0059] When the telescopic end of the electric push rod 17 is retracted, the rack 15 is driven to move downward, thereby rotating the gear 14, driving the rotating rod 11 to rotate, and flipping the cover plate 12 upward.

[0060] In this embodiment, the trigger member 18 includes a movable rod 19, a fixed tube 20 and a spring 21. The movable rod 19 is slidably inserted in the fixed tube 20, one end of the spring 21 is fixedly connected to the inner wall of the fixed tube 20, and the other end of the spring 21 is fixedly connected to the movable rod 19. The bottom of the fixed tube 20 is fixedly connected to the upper surface of the floating block 6, and the end of the movable rod 19 away from the fixed tube 20 can contact the contact switch 16.

[0061] One end of the heat conducting pipe 7 is provided with a through hole 22 for the movable rod 19 to pass through.

[0062] It should be noted that when the movable rod 19 contacts the contact switch 16, the telescopic end of the electric push rod 17 is in an extended state;

[0063] When the movable rod 19 is disconnected from the contact switch 16, the telescopic end of the electric push rod 17 is retracted;

[0064] When the video front-end box 2 is used in winter, the power supply to the electric push rod 17 and the water pump 5 can be turned off.

[0065] By adopting the above scheme, through the use of the trigger member 18, after the water pump 5 completes the water replenishment of the heat conducting tube 7, the water level in the heat conducting tube 7 rises, and the float 6, under the buoyancy of the water in the heat conducting tube 7, pushes the movable rod 19 to contact the contact switch 16, compresses the spring 21, and the telescopic end of the electric push rod 17 extends, so that the cover plate 12 is flipped downward, and the air flow channel of the air vent 10 is reduced, and water cooling is mainly used. When the water level in the heat conducting tube 7 drops, the float 6 moves downward, and the spring 21 continues to extend, so that the movable rod 19 continues to contact the contact switch 16. When the water level continues to drop, after the spring 21 is fully expanded, the movable rod 19 is disconnected from the contact switch 16. At this time, the telescopic end of the electric push rod 17 retracts, and the cover plate 12 is flipped upward, so that the air flow channel of the air vent 10 is expanded, ensuring that the video front-end box 2 can still dissipate heat through the air flow channel when the water cooling effect is lost.

[0066] In this embodiment, a filter 23 for filtering dust is detachably installed in the air vent 10 .

[0067] It should be noted that the filter 23 is fixed with bolts. When the electric push rod 17 fails, the filter 23 can be disassembled, the electric push rod 17 can be disassembled and repaired, and the filter 23 can be cleaned regularly.

[0068] The above solution is adopted: Since there is a lot of dust on the railway line, the use of the filter 23 can effectively prevent dust from entering the video front-end box 2 through the air vent 10, and can provide dust protection for the internal components.
