Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a perimeter-mounted monitoring system with a protective structure. Background Technology

[0002] A perimeter camera is a security device primarily used to monitor the boundaries or limits of a unit or place, such as walls, fences, gates, etc.

[0003] Currently, perimeter surveillance cameras are typically protected by adding protective covers to the outside of the cameras. However, these covers have simple structures and poor dust protection. Once dust adheres to the cover, it can affect the use of the cameras. Therefore, we propose an improved perimeter surveillance system with a protective structure. Utility Model Content

[0004] The main objective of this invention is to provide a perimeter monitoring system with a protective structure, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A perimeter monitoring system with a protective structure includes a mounting base and a perimeter camera. A mounting plate is fixedly connected to one side of the mounting base. A drive shaft is rotatably sleeved on the mounting plate. A cam is fixedly sleeved on the lower outer wall of the drive shaft. A fixing plate and a hanger are fixedly connected to the lower end of the mounting plate. A push rod is slidably sleeved on the fixing plate. A sleeve is fixedly sleeved inside the hanger. A push plate is fixedly connected to one end of the push rod, and a piston is fixedly connected to the other end through the sleeve. An annular nozzle is fixedly sleeved on the outer wall of the perimeter camera. An output pipe is fixedly connected between the annular nozzle and the sleeve. A small water collection tank is fixedly connected to one side of the upper end of the mounting plate. An input pipe is fixedly connected to the upper end of the sleeve near the output pipe. A water guide pipe is fixedly connected between the small water collection tank and the input pipe.

[0007] As a further embodiment of this utility model, a rotating rod is rotatably connected to one side of the middle part of the upper end of the mounting plate, and a driving blade is fixedly sleeved on the upper end of the rotating rod.

[0008] As a further embodiment of this utility model, a driven gear is fixedly sleeved on the outer wall near the lower end of the rotating rod, and a driving gear is fixedly sleeved on the outer wall of the drive shaft, with the driving gear and the driven gear meshing with each other.

[0009] As a further embodiment of this utility model, a servo motor is fixedly mounted on one side of the mounting base, the output end of the servo motor is fixedly connected to the drive shaft, and the lower end of the servo motor is fixedly mounted on the mounting plate.

[0010] As a further embodiment of this utility model, a spring is fixedly connected between the push plate and the fixed plate, and the spring is movably sleeved on the outer wall of the push rod.

[0011] As a further embodiment of this utility model, a filter screen is fixedly sleeved on the upper end of the small water collection tank, and solenoid valves are rotatably installed on the outer walls of both the water guide pipe and the input pipe.

[0012] As a further embodiment of this utility model, an outlet valve and an inlet valve are rotatably connected inside the output pipe and the input pipe, respectively. The outlet valve is rotatably located on the side away from the sleeve, and the inlet valve is rotatably located on the side closer to the sleeve.

[0013] The beneficial effects of this utility model are as follows:

[0014] By setting up a small water collection tank to filter and collect rainwater, when dust appears on the perimeter camera cover, the solenoid valve on the water guide pipe can be opened while the solenoid valve on the input pipe is closed. Clean water from the small water collection tank is introduced into the sleeve through the input pipe. At the same time, the servo motor is started, which drives the cam to rotate through the drive shaft. This, in turn, drives the pusher to move the push rod through the push plate, which in turn moves the piston inside the sleeve, sending the water flow into the output pipe. Finally, the water is sprayed onto the perimeter camera cover through the annular nozzle to clean the dust. After spraying, the solenoid valve on the water guide pipe is closed, and the solenoid valve on the input pipe is opened. At this time, the piston reciprocates under the action of the motor. In conjunction with the inlet and outlet valves, external airflow is sent into the sleeve through the input pipe and then into the annular nozzle through the output pipe. Finally, the airflow is blown out to dry the water on the camera. Generally, periodic air supply can prevent dust from adhering to the perimeter camera cover. If blowing alone cannot achieve the desired cleaning effect, water spraying can be used as an auxiliary cleaning method to improve the cleaning effect.

[0015] Through the meshing relationship between the driving gear and the driven gear, the rotation of the drive shaft will synchronously drive the rotating rod to rotate, which in turn drives the driving blades to rotate, thereby driving away the birds that are perched on the device and preventing the birds from affecting the use of the device, which is practical.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, a perimeter monitoring system with a protective structure includes a mounting base 1 and a perimeter camera 25. A mounting plate 2 is fixedly connected to one side of the mounting base 1. A drive shaft 4 is rotatably sleeved on the mounting plate 2. A cam 9 is fixedly sleeved on the lower outer wall of the drive shaft 4. A fixing plate 10 and a hanging piece 14 are fixedly connected to the lower end of the mounting plate 2. A push rod 11 is slidably sleeved on the fixing plate 10. A sleeve 15 is fixedly sleeved inside the hanging piece 14. A push plate 12 is fixedly connected to one end of the push rod 11, and a piston 16 is fixedly connected to the other end through the sleeve 15. An annular nozzle 26 is fixedly sleeved on the outer wall of the perimeter camera 25. An output pipe 17 is fixedly connected between the annular nozzle 26 and the sleeve 15. A small water collection tank 18 is fixedly connected to one side of the upper end of the mounting plate 2. An input pipe 21 is fixedly connected to the upper end of the sleeve 15 near the output pipe 17. A water guide pipe 20 is fixedly connected between the small water collection tank 18 and the input pipe 21.

[0023] In this embodiment, a rotating rod 3 is rotatably connected to one side of the upper middle part of the mounting plate 2. A driving blade 5 is fixedly sleeved on the upper end of the rotating rod 3. The driving blade 5 can be rotated by the rotating rod 3 to drive away birds.

[0024] In this embodiment, a driven gear 7 is fixedly sleeved on the outer wall near the lower end of the rotating rod 3, and a driving gear 8 is fixedly sleeved on the outer wall of the drive shaft 4. The driving gear 8 and the driven gear 7 mesh with each other. When the drive shaft 4 rotates, it drives the driving gear 8 to rotate, which in turn drives the driven gear 7 to rotate, and thus drives the rotating rod 3 to rotate.

[0025] In this embodiment, a servo motor 6 is fixedly installed on one side of the mounting base 1. The output end of the servo motor 6 is fixedly connected to the drive shaft 4. The lower end of the servo motor 6 is fixedly installed on the mounting plate 2, and the drive shaft 4 is driven to rotate by the servo motor 6.

[0026] In this embodiment, a spring 13 is fixedly connected between the push plate 12 and the fixed plate 10. The spring 13 is movably sleeved on the outer wall of the push rod 11. When the push plate 12 is not under the pressure of the cam 9, the spring 13 can drive the push plate 12 to rebound, thereby cooperating with the rotation of the cam 9 to form the reciprocating motion effect of the push plate 12.

[0027] In this embodiment, a filter screen 19 is fixedly sleeved on the upper end of the small water collection tank 18 to filter the collected rainwater. Solenoid valves 22 are rotatably installed on the outer walls of the water guide pipe 20 and the input pipe 21. The two solenoid valves 22 are in an open and closed state. Under normal circumstances, only the solenoid valve 22 on the input pipe 21 needs to be opened. The solenoid valve 22 on the water guide pipe 20 is opened only when cleaning water is needed.

[0028] In this embodiment, an outlet valve 23 and an inlet valve 24 are rotatably connected to the output pipe 17 and the input pipe 21, respectively. The outlet valve 23 is rotatably located on the side away from the sleeve 15, and the inlet valve 24 is rotatably located on the side close to the sleeve 15. When the piston 16 moves toward the output pipe 17, the outlet valve 23 automatically opens and the inlet valve 24 automatically closes under the action of air pressure. When the piston 16 moves away from the output pipe 17, the outlet valve 23 automatically closes and the inlet valve 24 automatically opens.

[0029] It should be noted that this utility model is a perimeter monitoring system with a protective structure. During use, the servo motor 6 is periodically activated to drive the drive shaft 4 to rotate, which in turn drives the cam 9 to rotate. Through the characteristics of the spring 13, the push plate 12 can drive the push rod 11 to reciprocate, which in turn drives the piston 16 to reciprocate within the sleeve 15. As the piston 16 reciprocates, the outlet valve 23 and the inlet valve 24 alternately open and close, thereby allowing external air to enter the sleeve 15 through the upper end of the input pipe 21 of the solenoid valve 22, and then enter the annular nozzle 2 through the output pipe 17. The air is sprayed from inside the 6th nozzle to blow off the dust adhering to the protective cover of the perimeter camera 25. When the dust removal by blowing alone cannot achieve the desired effect, the solenoid valve 22 on the input pipe 21 can be closed and the solenoid valve 22 on the water guide pipe 20 can be opened. The water in the small water collection tank 18 that collects rainwater in rainy days is introduced into the input pipe 21 through the water guide pipe 20 and enters the sleeve 15. Then, under the reciprocating motion of the piston 16, it is sprayed out from the nozzle of the annular nozzle 26 according to the same principle to wash the dust adhering to the perimeter camera 25, improve the cleaning effect, and ensure the normal use of the perimeter camera 25.

[0030] During the rotation of the drive shaft 4, the driven gear 7 is driven by the drive gear 8, which in turn drives the rotating rod 3 to rotate, and in turn drives the driving blade 5 to rotate. By periodically rotating the driving blade 5, birds can be driven away to prevent them from staying on the device and affecting its operation.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
