[0002] The intelligent monitoring device for construction project management is a monitoring device designed for construction sites. It combines high-tech visual monitoring technology, data analysis and intelligent functions to improve the safety, efficiency and management level of the construction process. The intelligent monitoring camera can observe the construction site in real time to ensure that all activities are within the controllable range and detect potential problems in time. In addition, through the integrated artificial intelligence algorithm, the camera can automatically identify risky behaviors, such as not wearing a hard hat, crowded personnel, etc., and issue an alarm in time to ensure construction safety.

[0003] However, when the existing intelligent surveillance cameras are used for a long time, due to the distribution of internal electrical components and the structural design of the camera, the heat between the components is not effectively conducted and dissipated, causing the temperature of the components such as the processor or power module to rise significantly, resulting in local overheating of the camera module. This is especially obvious when operating under high load and the ambient temperature is high. Long-term high temperature will cause the performance of the equipment to decline and even damage the internal circuit. Although the existing surveillance cameras have built-in cooling fans, the cooling fans need to centrally dissipate the heat as a whole, so that most of the internal airflow cannot effectively contact the heat source, resulting in heat accumulation and affecting the cooling efficiency of the surveillance camera.

DETAILED DESCRIPTION

[0026] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0027] According to the attached Figure 1 and attached Figure 2 As shown, an intelligent monitoring device for construction project management includes a bracket 100 and a monitoring camera 200 arranged on the bracket 100; in specific implementation, the monitoring camera 200 is installed at the monitoring point through the bracket 100, and the installation angle of the monitoring camera 200 is adjusted, so as to complete the intelligent monitoring of construction project management. Among them, the monitoring camera 200 includes a rear end housing 201, a front end cover 202, a lens 203, a protective cover 204, a camera module 205 and a cooling fan 206; when working, the cooling fan 206 is driven to work, and the camera module 205 is cooled by air.

[0028] Specifically, the rear end shell 201 is fixedly connected to the front end cover 202, the lens 203 is installed on the front end cover 202, the protective cover 204 is located above the rear end shell 201 and the front end cover 202, the protective cover 204 is fixedly connected to the rear end shell 201 and the front end cover 202, the camera module 205 is installed inside the front end cover 202, the cooling fan 206 is installed inside the rear end shell 201, and the rear end shell 201 is provided with an air inlet 207 and an air outlet 208, the position of the air inlet 207 corresponds to the position of the cooling fan 206, and the position of the air outlet 208 corresponds to the position of the camera module 205.

[0029] It should be understood that when the cooling fan 206 is working, air is taken in through the air inlet 207 , the cooling fan 206 cools the camera module 205 , and discharges the hot air from the air outlet 208 to dissipate heat for the surveillance camera 200 .

[0030] In addition, according to the attached Figure 3 As shown, in order to reduce the heat accumulation generated inside the surveillance camera 200 and improve the internal heat dissipation efficiency of the surveillance camera 200, in the present embodiment, an air flow gap is provided between the protective cover 204 and the rear end shell 201, and an auxiliary heat dissipation mechanism is provided on the air flow gap, and the auxiliary heat dissipation mechanism includes a first heat dissipation fin 2011 and a first air duct 2012 installed on the rear end shell 201, thereby facilitating the heat dissipation of the rear end shell 201 and the front end cover 202.

[0031] Furthermore, according to the attached Figure 3 and attached Figure 4 As shown, the first air duct 2012 is provided with an air inlet end and an air outlet end, two groups of air collecting hoods 2013 are symmetrically installed on the air inlet end of the first air duct 2012, and a filter plate 2014 is installed on the air collecting hoods 2013, and a first partition plate 2015 is installed between the two groups of air collecting hoods 2013, which is used to separate the two groups of air collecting hoods 2013 and divert and guide the air entering the air collecting hoods 2013 so that the air enters the first air duct 2012, thereby dissipating the heat of the first heat dissipating fins 2011, and a gap is provided between each fin of the first heat dissipating fin 2011, and the gap corresponds to the air outlet end of the first air duct 2012, so that the heat dissipating airflow in the first air duct 2012 can pass through the first heat dissipating fins 2011, and the first heat dissipating fins 2011 are fully cooled.

[0032] In yet another embodiment, according to the attached Figure 2 , Attachment Figure 5 and attached Figure 6As shown, a guide mechanism 300 is provided in the rear end shell 201, and the guide mechanism 300 includes a second partition 301 installed in the rear end shell 201, and a heat dissipation channel is opened in the second partition 301, and a plurality of guide plates 302 are provided in the heat dissipation channel, and the guide plates 302 are initially arranged in parallel.

[0033] It should be noted that when the cooling fan 206 is driven to work, the cooling fan 206 drives the cooling airflow to enter from the air inlet 207, so that the cooling airflow passes through the inside of the cooling channel, and the cooling airflow is guided by the setting of the guide plate 302, thereby controlling the flow path of the cooling airflow. Subsequently, the cooling airflow flows toward the position of the camera module 205 through the cooling channel, and is discharged through the air outlet 208.

[0034] When the guide plate 302 is in a parallel state, the flow path of the heat dissipation airflow is in a normal state, and the heat dissipation airflow moves in parallel to dissipate heat for the camera module 205 as a whole.

[0035] When the guide plate 302 is tilted upward, the flow path of the heat dissipation airflow is tilted upward, and the heat dissipation airflow flows upward to dissipate heat for electronic components on the flow path, thereby locally dissipating heat for the upper layer of the camera module 205.

[0036] When the guide plate 302 is tilted downward, the flow path of the heat dissipation airflow is tilted downward, and the heat dissipation airflow flows downward to dissipate heat for electronic components on the flow path, thereby locally dissipating heat for the lower layer of the camera module 205.

[0037] Specifically, according to the attached Figure 7 As shown, connecting rods 304 are symmetrically provided on the second partition 301 , and a plurality of first swing arms 305 are rotatably connected to the connecting rods 304 via a rotating shaft. A first connecting shaft 306 is installed on the guide plate 302 , and the first connecting shaft 306 is connected to the bearing of the second partition 301 .

[0038] It should be noted that the first swing arm 305 is fixedly connected to the first connecting shaft 306. When the driving connecting rod 304 moves up and down, the connecting rod 304 drives the first swing arm 305 to move synchronously, so that the first swing arm 305 rotates around the connecting part of the rotating shaft, thereby forcing the guide plate 302 to move synchronously, adjusting the guide plate 302 to rotate upward or downward, thereby changing the flow path of the heat dissipation airflow, and facilitating the heat dissipation treatment of the camera module 205 locally.

[0039] Furthermore, a guide column 307 is installed on the connecting rod 304, and a guide sleeve 308 is slidably connected to the guide column 307. The sliding connection between the guide column 307 and the guide sleeve 308 facilitates the limiting of the up and down movement of the connecting rod 304, thereby improving the stability of the up and down movement of the connecting rod 304. The guide sleeve 308 is installed on the second partition plate 301. A spring 309 is also provided on the guide column 307. One end of the spring 309 is fixedly connected to the connecting rod 304, and the other end of the spring 309 is fixedly connected to the guide sleeve 308. Through the setting of the spring 309, when the spring 309 is squeezed or stretched, the spring 309 has a restoring force, thereby facilitating the driving of the connecting rod 304 to reset, so that the guide plate 302 is in a parallel state.

[0040] In addition, according to the attached Figure 5 As shown, two groups of second air ducts 303 are symmetrically installed on the second partition plate 301, and a boss 3031 is provided at one end of the second air duct 303 close to the camera module 205, an inclined surface is provided at the end of the boss 3031 facing the camera module 205, and a plurality of air flow holes 3032 are opened on the inclined surface, and an air flow port 3033 is provided at one end of the second air duct 303 close to the cooling fan 206, and the air flow holes 3032 and the air flow ports 3033 are both connected to the interior of the second air duct 303.

[0041] It should be understood that when the cooling fan 206 is driven to work, the cooling air flows into the second air duct 303 through the air flow port 3033, and is discharged outwardly through the air flow hole 3032, thereby cooling the camera module 205; in the present embodiment, through the action of the air flow hole 3032, the cooling air flow in the second air duct 303 is ejected from the air flow hole 3032, and the end of the camera module 205 away from the cooling fan 206 is cooled, and through the setting of the air flow hole 3032, the cooling air flow ejected from the air flow hole 3032 is opposite to the flow path of the cooling air flow in the cooling fan 206, thereby disturbing the internal flow path, so that the cooling air flow is fully in contact with the camera module 205, and the cooling air flow is discharged from the air outlet 208.

[0042] In another embodiment, according to the attached Figure 2 , Attachment Figure 8 , Attachment Fig. 9 , Attachment Fig.10 and attached Fig.11 As shown, a monitoring mechanism 400 is provided on the camera module 205, and the monitoring mechanism 400 includes two groups of second heat dissipation fins 401 symmetrically installed on the camera module 205, and a heat conducting plate 402 is installed on the second heat dissipation fins 401, and an electric push rod 403 is installed on the heat conducting plate 402, and a temperature sensor is also installed on the inner wall of the electric push rod 403, and the temperature sensor is fixedly connected to the heat conducting plate 402, and the electric push rod 403 is also provided with a telescopic end 405.

[0043] Specifically, a fixing frame 406 is provided between the two sets of second heat dissipation fins 401, and a second connecting shaft 407 is connected to the fixing frame 406 by a bearing, a second swing arm 408 is installed on the second connecting shaft 407, and a guide groove 409 is symmetrically provided on the second swing arm 408, a guide rod 410 is slidably connected in the guide groove 409, and the guide rod 410 is fixedly connected to the telescopic end 405. The fixing frame 406 is fixedly connected to the camera module 205.

[0044] It should be noted that according to the attached Fig. 9 , Attachment Fig.10 and attached Fig.11 As shown, when the camera module 205 is locally overheated, the heat is conducted to the second heat sink fin 401 at the heat source position, and through the setting of the heat conduction plate 402, the heat is synchronously conducted to the temperature sensor in the electric push rod 403, so that the temperature sensor detects the internal temperature.

[0045] When the temperature of the upper or lower part of the camera module 205 reaches the threshold set by the temperature sensor, the temperature sensor controls the electric push rod 403 to perform telescopic movement, pulling the telescopic end 405 to move toward the inside of the electric push rod 403, thereby controlling the second swing arm 408 to drive the second connecting shaft 407 to rotate. While the telescopic end 405 drives the second swing arm 408 to rotate, the setting of the guide groove 409 and the guide rod 410 provides space for the movement of the telescopic end 405, thereby improving the smoothness of the movement of the telescopic end 405 and avoiding jamming.

[0046] It should be noted that when one group of electric push rods 403 controls the telescopic end 405 to extend, the other group of electric push rods 403 controls the telescopic end 405 to retract, and when one group of electric push rods 403 controls the telescopic end 405 to retract, the other group of electric push rods 403 controls the telescopic end 405 to extend.

[0047] When the temperatures of the upper part and the lower part are both within the set threshold values ​​of the temperature sensors, the two sets of electric push rods 403 remain stationary and do not perform telescopic movements, thereby facilitating heat dissipation.

[0048] A gear 411 is also installed on the second connecting shaft 407 , and a rack plate 412 is meshedly connected to the gear 411 . A connecting plate 413 is installed on the rack plate 412 , and the connecting plate 413 is fixedly connected to the connecting rod 304 .

[0049] When the second connecting shaft 407 rotates, the driving gear 411 rotates synchronously, and the gear 411 is meshed with the rack plate 412 to drive the rack plate 412 to move, so that the rack plate 412 drives the connecting rod 304 to move synchronously to adjust the up and down direction of the guide plate 302.

[0050] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
