Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-4 , Figure 7A building security monitoring device includes a bracket 1, with a camera body 9 fixedly connected to the top of the bracket 1. An annular groove 10 is provided on the upper side of the outer wall of the bracket 1. Protective covers 1-2 and 2-8 are respectively provided on the left and right sides of the outer wall of the camera body 9. A transparent window 3 is fixedly connected to the inner wall of the right end of protective cover 1-2. A fan shroud 5 is fixedly connected to the top left side of protective cover 1-2. Several cylinders 14 are fixedly connected to the inner wall of the left end of the fan shroud 5, penetrating both the inner and outer sides of the fan shroud 5. Exhaust pipes 6 are sequentially fixed to the right side of the cylinders 14 corresponding to the right side of the fan shroud 5. The other end of the exhaust pipe 6 is fixed... A wind chamber box 4 is connected. The left end of the wind chamber box 4 is fixedly connected to the upper right side of the protective cover 2. An air outlet 21 is opened at the bottom end of the wind chamber box 4. An inclined frame 22 is fixedly connected to the bottom end of the wind chamber box 4 and the inner wall of the bottom end outside the air outlet 21. A suction pipe 7 is fixedly connected to the left end of the cylinder 14. The other end of the suction pipe 7 is fixedly connected to the top left side of the protective cover 2 away from the cylinder 14. A cross 15 is fixedly connected to the middle of the inner wall of the cylinder 14. A motor 16 is fixedly connected to the middle of the left end of the cross 15. The drive end of the motor 16 passes through the right side of the cross 15 and is fixedly connected to an impeller 17.

[0031] To further explain, protective covers 1 2 and 2 8 are installed on the outside of the camera body 9. This provides reliable protection for the camera body 9 and effectively prevents external dust from directly covering the lens, thus avoiding affecting the shooting effect. After the motor 16 is powered on, the impeller 17 starts to rotate, generating wind. The wind is blown into the air chamber box 4 through the exhaust pipe 6 and then blown out from the air outlet 21. Due to the tilted setting of the inclined bracket 22, the blown air will blow towards the surface of the transparent window 3, blowing away the dust on the surface of the transparent window 3, preventing dust from adhering, and ensuring that the camera's shooting effect is not affected.

[0032] Example 2

[0033] Please see Figures 5-6 Further, based on Embodiment 1, the bottom end of Protective Cover 1 2 is fixedly connected to a ventilation box 11 outside the vent. A filter plate 12 is provided on the inner wall of the ventilation box 11. A limiting block 18 is fixedly connected to the middle of the front end of the filter plate 12. A sliding cylinder 13 is fixedly connected to the middle of the front side of the bottom end of the ventilation box 11. A sliding bolt 19 is slidably connected to the inner wall of the front side of the top end of the sliding cylinder 13. The shape of the rear side of the outer wall of the sliding bolt 19 matches the shape of the inner wall of the front end of the limiting block 18. A spring 20 is fixedly connected to the bottom end of the sliding bolt 19. The bottom end of the spring 20 is fixedly connected to the inner wall of the sliding cylinder 13. A square groove 23 is opened in the middle of the upper side of the right end of Protective Cover 2 8. An insert 29 is fixedly connected to the middle of the upper side of the left end of Protective Cover 1 2. The shape of the outer wall of the insert 29 matches the shape of the inner wall of the square groove 23. The shapes of the inner walls of the lower sides of the opposite ends of Protective Cover 1 2 and Protective Cover 2 8 both match the shape of one side of the inner wall of the annular groove 10.

[0034] To further explain, when the impeller 17 rotates, a negative pressure suction force is generated on one side of its back. Through the extension of the suction pipe 7, the air between the protective cover 1 2 and the protective cover 2 8 can be sucked in. At the same time, the outside air located at the bottom ventilation port of the protective cover 1 2 will continuously enter the space between the protective cover 1 2 and the protective cover 2 8, and then be sucked in from the bottom of the suction pipe 7. Before the outside air enters, it needs to pass through the filter screen 12. The filter screen part of the filter screen 12 can filter dust and impurities in the air. The filtered air enters the protective cover 1 2 and the protective cover 2 8, which can carry away the heat emitted by the camera body 9 during operation, and then is discharged through the bottom of the suction pipe 7.

[0035] To clean the filter screen 12, simply press the sliding bolt 19, causing the bottom of the sliding bolt 19 to squeeze the spring 20 and retract into the slide cylinder 13, thus releasing the limit block 18. The filter screen 12 can then be pulled out from the port box 11 for cleaning.

[0036] Example 3

[0037] Please see Figures 8-9 Based on Embodiment 1, the protective cover 2 is further provided with a horizontal plate 30 fixedly connected to the middle of the left side of both the front and rear ends. The horizontal plate 30 has a hole 31 on the left side of the inner wall of both the front and rear ends. The protective cover 8 is provided with a support block 27 fixedly connected to the upper side of the horizontal plate 30. The support block 27 has a plug 26 slidably connected to the right side of the inner wall of the support block 27. The shape of the bottom end of the plug 26 matches the shape of the inner wall of the hole 31. The top end of the plug 26 is fixedly connected with a pressure plate 24. The top end of the pressure plate 24 is fixedly connected with a pull rod 28. The bottom end of the pressure plate 24 is fixedly connected to a spring 25 outside the plug 26. The bottom end of the spring 25 is fixedly connected to the top end of the support block 27.

[0038] To further explain, when the camera body 9 needs to be inspected, pull up the lever 28 to move the pressure plate 24 upward, stretch the spring 25, and at the same time, the plug 26 moves upward with the pressure plate 24 and is pulled out from the socket 31, releasing the limit between the protective cover 2 and the protective cover 8. Then, these two protective covers can be removed from the outside of the camera body 9 to facilitate the maintenance of the camera body 9. When installing, simply reverse the above steps.

[0039] Working principle: First, the protective cover 2 and the protective cover 8 set on the outside of the camera body 9 can protect the camera body 9 and prevent external dust from directly covering the lens of the camera body 9 and affecting the camera body 9's shooting effect. The motor 16 is connected to the power supply, which makes the impeller 17 rotate, thereby generating wind. The wind is blown into the air chamber box 4 through the exhaust pipe 6, and then blown from the air outlet 21 towards the surface of the transparent window 3 with the tilt angle of the inclined bracket 22, thereby blowing away the dust attached to the surface of the transparent window 3 and preventing dust from adhering to the surface of the transparent window 3 and affecting the camera body 9's shooting effect.

[0040] While generating wind, the impeller 17 also generates negative pressure suction on its back side. Through the extension of the suction pipe 7, it draws in the air between the protective cover 1 2 and the protective cover 2 8. Outside air located at the bottom vent of the protective cover 1 2 will continuously enter the space between the protective cover 1 2 and the protective cover 2 8, and then continue to be drawn in from the bottom of the suction pipe 7. Before the outside air enters from the vent, it will pass through the filter plate 12. The filter part of the filter plate 12 will filter out dust and impurities in the air. The air that enters the protective cover 1 2 and the protective cover 2 8 will carry away the heat emitted by the camera body 9 during operation and be discharged from the bottom of the suction pipe 7 into the protective cover 1 2 and the protective cover 2 8. By pressing the sliding bolt 19, the bottom of it will squeeze the spring 1 20 and retract into the slide cylinder 13, thereby releasing the limit block 18. Then the filter plate 12 can be pulled out from the port box 11 to clean the filter part of the filter plate 12.

[0041] When the camera body 9 needs to be repaired, pull up the lever 28 to move the bottom of it along with the pressure plate 24 upwards and stretch the spring 25. At the same time, the plug 26 is pulled upwards by the pressure plate 24 and pulled out from the socket 31. This releases the limit between the protective cover 1 2 and the protective cover 2 8. Then, remove the protective cover 1 2 and the protective cover 2 8 to repair the camera body 9. When installing the protective cover 1 2 and the protective cover 2 8, simply reverse the above steps.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
