[0026] Example 1

[0027] A power safety monitoring device that is easy to maintain, such as Figures 1 to 4 As shown, the device includes a housing 1. Multiple positioning protrusions 4 are arranged in a ring array on the inner wall of the housing 1. A camera body 5 is located at one end of the inner wall of the housing 1. The outer wall of the camera body 5 contacts and engages with the multiple positioning protrusions 4. The intervals between the multiple positioning protrusions 4 and the outer wall of the camera body 5 form a heat dissipation channel 6. An air intake grille is located at the other end of the housing 1. A cooling fan 8 is located on the inner wall of the housing 1 near the air intake grille. A guide block 7 is located on the side of the cooling fan 8 near the camera body 5, with the tip of the guide block 7 facing the cooling fan 8. There is a gap between the guide block 7 and the inner wall of the housing 1, which communicates with the heat dissipation channel 6. An air jet 9, communicating with the heat dissipation channel 6, is opened at one end of the housing 1. The air jet 9 is perpendicular to the camera end of the camera body 5. A fixing bracket 3 is connected to the top of the housing 1 via a connecting mechanism 2.

[0028] The connecting mechanism 2 includes a rotating frame 10 and a rotating rod 11. The rotating frame 10 is rotatably connected to the bottom outer wall of the fixed frame 3. The rotating rod 11 is rotatably connected to the bottom of the rotating frame 10. An adjusting motor for driving the rotating rod 11 to rotate is installed on one side of the rotating frame 10. A connecting frame 12 is fixed on the outer wall of the housing 1. A slot for sliding cooperation with the connecting frame 12 is opened at the bottom of the rotating rod 11. A limiting component for fixing the connecting frame 12 is provided on the outer wall of the rotating rod 11. A driven gear 16 coaxial with the rotating frame 10 is connected to the top of the rotating frame 10. A driving gear 17 is driven and meshed on one side of the driven gear 16. A drive motor 18 is installed on the outer wall of the fixed frame 3. The output shaft of the drive motor 18 is connected to the driving gear 17.

[0029] The limiting assembly includes a positioning frame 13 and a limiting frame 14. The positioning frame 13 is fixed to the outer wall of the top end of the rotating rod 11. The limiting frame 14 is slidably fitted to the outer wall of the top end of the rotating rod 11. The bottom end of the limiting frame 14 is inserted into the connecting frame 12. A pulling rod 15 is slidably fitted to the outer wall of the top end of the positioning frame 13. The bottom end of the pulling rod 15 is connected to the limiting frame 14. A limiting spring is sleeved on the outer wall of the pulling rod 15. The two ends of the limiting spring are respectively connected to the positioning frame 13 and the limiting frame 14.

[0030] In use, the mounting bracket 3 is fixed to the installation position with bolts, and the camera body 5 monitors its orientation. The cooling fan 8 pours external airflow into the housing 1, and the guide block 7 diverts the airflow to the cooling channel 6. The gas flows along the cooling channel 6 to the jet nozzle 9 to cool the camera body 5. The airflow enters the jet nozzle 9 and is collected and ejected, forming an "air curtain" of airflow on the side of the lens of the camera body 5, preventing dirt and dust from approaching the lens. During monitoring, the drive motor 18 drives the drive gear 17 to rotate, which in turn drives the driven gear 16 to rotate, causing the housing 1 to rotate and changing the circumferential orientation of the camera body 5. At the same time, the motor drives the rotating rod 11 to rotate relative to the rotating frame 10, changing the tilt angle of the housing 1 and adjusting the vertical orientation of the camera body 5. When the camera body 5 needs to be removed for maintenance, the pull rod 15 is pulled upward, the limit spring is compressed and deformed, and the limit frame 14 is moved upward and disengaged from the connecting frame 12. At this time, the connecting frame 12 can be removed from the rotating rod 11, and the housing 1 can be removed.

[0031] By setting up positioning protrusions 4, heat dissipation channels 6, guide blocks 7 and jet nozzles 9, the heat dissipation airflow generated by the cooling fan 8 is gathered and sprayed out, forming an "air curtain" composed of airflow on the side of the lens of the camera body 5, which prevents dirt and dust from approaching the lens and avoids dirt and dust from gradually accumulating on the lens surface.

[0032] With the connection mechanism 2 in place, when the camera body 5 needs to be removed for maintenance, the housing 1 can be removed by pulling the lever 15 upwards, making it easy to remove the camera body 5 for maintenance.

[0033] Example 2

[0034] A power safety monitoring device that is easy to maintain. This embodiment is based on embodiment 1 and makes the following improvements, such as... Figure 1 As shown, an indicator and warning component 19 is fixed to the outer wall of the top of the housing 1. The indicator and warning component 19 includes a laser indicator module, a sound generation module, and a control module.

[0035] When damage or theft of the power system is observed in the background, the personnel can issue a warning sound through the sound module and emit a flashing indicator beam through the laser indicator module to warn the perpetrators that they have been discovered and to stop the damage or theft. When the outside environment is dark or the power system malfunctions and needs repair at night, the personnel can drive the housing 1 to move through the connecting mechanism 2 so that the laser indicator module points to the location to be repaired, making it easier for maintenance personnel to confirm the location to be repaired.

[0036] By incorporating the indicator and warning component 19, damage to or theft of the power system can be prevented, and the location of the power system can be indicated to maintenance personnel in dimly lit environments or at night.

[0037] Working principle: During use, the mounting bracket 3 is fixed to the installation position with bolts. The camera body 5 monitors the orientation of the camera. The cooling fan 8 draws external airflow into the housing 1. The guide block 7 diverts the airflow to the cooling channel 6. The gas flows along the cooling channel 6 to the nozzle 9, cooling the camera body 5. The airflow enters the nozzle 9, gathers, and is ejected, forming an "air curtain" of airflow on one side of the lens of the camera body 5, preventing dirt and dust from approaching the lens. During monitoring, the drive motor 18 drives the drive gear 17 to rotate, which in turn drives the driven gear 16 to rotate, causing the housing 1 to rotate and changing the circumferential orientation of the camera body 5. At the same time, the motor-driven rotating rod 11 rotates relative to the rotating frame 10, changing the tilt angle of the housing 1. Adjust the vertical orientation of the camera body 5; when the camera body 5 needs to be removed for maintenance, pull the pull rod 15 upward, the limit spring is compressed and deformed, and the limit frame 14 moves upward and disengages from the connecting frame 12. At this time, the connecting frame 12 can be removed from the rotating rod 11, and the housing 1 can be removed; when damage or theft of the power system is observed in the background, the background personnel can issue a warning sound through the sound module and emit a flashing indicator beam through the laser indicator module to warn the person who committed the damage or theft that he has been discovered and to stop the damage or theft; when the outside environment is dark or the power system malfunctions at night and needs maintenance, the background can drive the housing 1 to move through the connecting mechanism 2 so that the laser indicator module points to the location to be repaired, so that the maintenance personnel can confirm the location to be repaired.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
