Engineering management can start from the feasibility study of the project and last until the end of the project, running through the entire process of the project.

[0003] In project management, the care of the project site and its construction assets is an indispensable item, which mainly reduces the occurrence of accidents of off-site personnel and protects project assets. At present, in addition to relying on manpower, the use of monitoring equipment is also indispensable for the care of the project site and its construction assets in project management. In order to ensure the long-term uninterrupted operation of the monitoring equipment, the heat dissipation of its working is one of the main ways. At present, the heat dissipation of the outdoor monitoring unit is mainly based on the heat dissipation of its own shell material and the natural ventilation heat dissipation of the bottom opening, and the heat dissipation effect is limited.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1-7 , a project management safety monitoring device, comprising a casing 1, a bottom and a rear opening of the casing 1, a bottom casing 2 is arranged at the bottom opening position, the bottom casing 2 extends into the casing 1 and abuts against the inner wall of the casing 1, the bottom casing 2 and the casing 1 are fixed by screws at the same time, a rear cover 6 is screwed to the rear opening position of the casing 1, a heat dissipation port 7 is opened on the rear cover 6, a fan 8 is screwed to the rear side surface of the rear cover 6 corresponding to the heat dissipation port 7, and the fan 8 is arranged to blow air toward the heat dissipation port 7;

[0029] An air inlet 14 is provided at the front bottom of the bottom shell 2, and a corner frame 15 is welded and installed on the bottom of the bottom shell 2 at the position of the air inlet 14. The corner frame 15 is filled with dust filter cotton 16 that blocks the air inlet 14. A plurality of inner support bars 9 are welded and installed on the inner walls of the casing 1 and the bottom shell 2 at equal intervals, and a ventilation duct 10 is formed between adjacent inner support bars 9. A monitoring body 4 is installed in the casing 1 on the inner side of the inner support bars 9, and a monitoring lens 5 at the front end of the monitoring body 4 is close to the front end of the casing 1. The front end of the casing 1 is transparently arranged at a position corresponding to the monitoring lens 5. A fixed base 23 is welded and installed on the bottom surface of the bottom shell 2, and a power cord of the monitoring body 4 passes through a power cord through-hole 24 on the bottom surface of the bottom shell 2.

[0030] When in use, the monitoring is installed from the fixed base 23. When in use, the monitoring body 4 and the fan 8 are powered on. The monitoring body 4 uses the monitoring lens 5 to shoot the monitoring field of view to complete the monitoring purpose. At the same time, the fan 8 is working and rotating, and the internal air is first blown out through the heat dissipation port 7. Under the internal low-pressure state, the external air will be filtered by the dust filter cotton 16 to filter dust and other foreign matter, and then enter the interior through the air inlet 14, and then be discharged by the fan 8 along the ventilation duct 10, thereby completing the forced circulation of air. When the air circulates through the interior, heat exchange is generated with the internal heat, and then the internal heat is dissipated through the circulation. The inner support bar 9 surrounds the monitoring body 4 to form a ventilation duct 10. When the air flows through the ventilation duct 10, the heat dissipation effect of the monitoring body 4 can be ensured.

[0031] In this embodiment, a protective cover 3 is provided above the casing 1, and both sides of the protective cover 3 extend downward to cover both sides of the casing 1. The length of the protective cover 3 is greater than the length of the casing 1. A rack 18 is welded and installed on the inner top wall of the protective cover 3 close to the top surface of the casing 1. The casing 1 and the back cover 6 have openings corresponding to the position of the rack 18. A motor 20 is installed in the casing 1 through a motor seat 21. The motor seat 21 is fixed to the top wall of the casing 1 by screws. A gear 19 is installed on the shaft of the motor 20 for transmission, and the gear 19 is meshed with the rack 18. In this embodiment, the motor 20 is a dual-axis stepping motor, so two gears 19 are also provided, and two groups of racks 18 are also provided on the protective cover 3.

[0032] The protective cover 3 provides top-to-bottom protection for the entire monitoring, and can also provide a sunshade effect for the monitoring lens 5. When the control motor 20 works and utilizes the meshing transmission relationship between the gear 19 and the rack 18 to push the protective cover 3 to extend toward the front side of the casing 1, the shielding surface above the field of view of the monitoring lens 5 is increased to enhance the sunshade effect. Conversely, when the protective cover 3 moves toward the rear side of the casing 1, the field of view of the monitoring lens 5 is restored, but the sunshade effect is reduced, and light is more likely to be obliquely projected onto the monitoring lens 5. The specific control is autonomously controlled according to the specific conditions on site.

[0033] In this embodiment, a fixing plate 22 is provided at the rear side of the monitoring body 4 in the casing 1, and a T-shaped block 11 is installed at each of the four sides of the rear side of the fixing plate 22. The T-shaped block 11 extends into the ventilation duct 10, and a baffle 12 is integrally formed on the top surface of the T-shaped block 11 and is installed to abut against the fixing plate 22. The T-shaped block 11 is threadedly connected with fixing bolts 13 that abut against the casing 1 and the bottom shell 2 at the position of the ventilation duct 10. A baffle bar 17 is installed in the casing 1 near the front end of the bottom shell 2, and the front end of the bottom shell 2 is tightly sealed against the baffle bar 17, and the baffle bar 17 is made of rubber.

[0034] The fixing plate 22 fixes the monitoring body 4 and also provides protection, while the blocking bar 17 increases the sealing of the connection between the bottom shell 2 and the bottom of the casing 1, reduces the possibility of rainwater infiltration through the gap, and improves the rainproof performance.
