[0070] Among them, in order to achieve the purpose of heat dissipation, the present device adopts the following technical solutions: a shell 30 is fixedly connected to the bottom of the shell 19, the shell 30 is arc-shaped, and a plurality of air outlets are opened on one side of the shell 30; a fan 31 is fixedly connected to the top of the shell 19, and a pipe 32 is fixedly connected to the air outlet of the fan 31, and one end of the pipe 32 is fixedly embedded in the other side of the shell 30; a support block 33 is fixedly connected to one side of the shell 19, and the support block 33 is fixedly sleeved on the outside of the pipe 32. When the camera body 18 is working, heat is generated. At this time, the fan 31 can be controlled to work, and then the camera body 18 can be blown by the action of the pipe 32, the shell 30 and the air outlet, so as to dissipate heat;

[0071] In order to achieve the purpose of installation, the device is implemented by the following technical solution: two mounting frames 34 are fixedly connected to the front and rear sides of the shell 19, and mounting holes 35 are opened inside the two mounting frames 34, which can facilitate the installation of the device.

[0072] The use process of the present invention is as follows: when using the present invention, the intelligent monitoring and shooting module 1 shoots the construction operation screen in real time, and then the video transmission module 3 transmits the video shot by the intelligent monitoring and shooting module 1, and then the operation action extraction module 4 receives the transmitted video, and extracts the video clip containing the operation action from the video, thereby realizing the extraction of the operation action. Since the illegal operation action storage library 2 stores the construction actions belonging to illegal operations, the intelligent comparison module 5 can then compare the extracted operation actions with the illegal operation actions stored in the illegal operation action storage library 2, so as to determine whether illegal operation actions occur during the construction operation. After the comparison result comes out, the comparison result transmission module 6 can transmit the comparison result to the central processing unit 7, and then the central processing unit 7 can control the alarm module 9 to perform the alarm work, and then the relevant personnel can stop it in time, thereby avoiding safety accidents caused by illegal operations, so that the safety monitoring of the construction operation can be realized;

[0073] The present invention designs a work punch-in and proofreading module 10, and employees can punch in when entering the construction site. At the same time, the real-time number of people in the construction site can be compared with the number of people punching in, so as to avoid the phenomenon of lack of people. When there is a lack of people, the alarm module 9 will also alarm, so as to timely remind relevant personnel to pay attention. Since the train approaching detection module 11 is designed, it can detect whether the train is close to the construction site. When the train is close, the intelligent push module 12 can transmit the information of the train approaching to the personal reminder module 13. Since each employee wears the personal reminder module 13, the personal reminder module 13 can receive the information pushed by the intelligent push module 12 and remind the employees to pay attention, thereby achieving the effect of early warning, and avoiding construction accidents.

[0074] The railway construction site is inside the tunnel. Harmful gases such as methane and carbon dioxide may be generated during construction inside the tunnel. At this time, the harmful gas concentration detection module 14 can detect the real-time concentration of the harmful gas. Since the safety value storage module 15 stores the safety value of the harmful gas, the over-standard comparison transmission module 16 can compare the concentration of the harmful gas detected by the harmful gas concentration detection module 14 with the safety value, so as to determine whether the concentration exceeds the standard. If it exceeds the standard, the alarm module 9 can issue an over-standard alarm. At this time, the intelligent ventilation module 17 can ventilate the inside of the tunnel, so as to avoid the harmful gas from affecting the health of employees;

[0075] After the intelligent monitoring shooting module 1 is used for a long time, the camera body 18 needs to be maintained. At this time, the camera body 18 needs to be disassembled. When disassembling, the knob 28 is turned so that the bidirectional screw 25 can be rotated. Since the bidirectional screw 25 has two threads with opposite spiral directions, the rotation of the bidirectional screw 25 can increase the distance between the two threaded blocks 26. At this time, the two card blocks 27 can be moved out of the two card slots, and then the camera body 18 is manually pushed upward, so that the connecting block 20 and the mounting plate 21 can be moved upward, and the pressure plate 22 and the prism 24 can be moved upward at the same time. At the same time, the spring 23 is compressed, and then the camera body 18 is rotated ninety degrees, so that the mounting plate 21 can overlap with the through groove, and then the camera body 18 can be removed, and then the camera body 18 can be maintained. After the maintenance is completed, the camera body 18 can be installed back by reverse operation;

[0076] The camera body 18 generates heat when it is working. At this time, the fan 31 can be controlled to work, and then the camera body 18 can be blown by the pipe 32, the shell 30 and the air outlet to dissipate the heat.

[0077] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention shall fall within the scope of protection claimed by the present invention.
