DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 and Figure 5 The present invention provides a technical solution: a monitoring device for multi-directional monitoring areas, comprising: a bracket 1 and a camera 6, a slider 2 is slidably connected to the middle of the bracket 1 through a slide groove, a rotating seat 3 is installed on the top of the slider 2, a connecting seat 4 is installed on the top of the rotating seat 3, a rotating shaft 5 is penetrated and connected in the middle of the connecting seat 4, and the camera 6 is installed on the top of the rotating shaft 5;

[0033] A red-hot external imaging sensor 7 and an induction radar module 8 are installed inside the camera 6. One side of the rotating shaft 5 is connected to a first motor 9 through a coupling. A rotating shaft 10 is installed at the bottom of the rotating seat 3 through a groove. A transmission gear set 11 is sleeved on the outer side of the rotating shaft 10. The transmission gear set 11 consists of two mutually meshing gears A and B. Gear A is connected to the rotating shaft 10, and an output shaft 12 that passes through the slider 2 is connected in the middle of gear B. The bottom of the output shaft 12 is connected to a second motor 13 through a coupling, and the bottom of the rotating shaft 10 is connected to the top of the slider 2 through a bearing.

[0034] In specific implementation, the monitoring device for the multi-directional monitoring area can monitor different angles through two groups of cameras 6 on the bracket 1 when it is necessary to monitor different directions. A red-hot external imaging sensor 7 and a sensing radar module 8 are installed inside each group of cameras 6. The red-hot external imaging sensor 7 mainly generates a thermal image by capturing infrared radiation emitted by an object. The sensing radar module 8 mainly senses surrounding objects. Through the cooperation of the red-hot external imaging sensor 7 and the sensing radar module 8, when the camera 6 detects a large rate of change in the distance of a person or object moving in other directions through the sensing radar module 8, the monitoring camera 6 will turn from the original angle to the specified direction for monitoring to achieve follow-up monitoring;

[0035] When following monitoring is performed, the second motor 13 can be started, and the second motor 13 will drive the top output shaft 12 to rotate through the coupling. The top of the output shaft 12 passes through the slider 2 and is connected to a transmission gear set 11. The transmission gear set 11 consists of two meshing gears A and gear B. Gear A is connected to the rotating shaft 10, and gear B is connected to the output shaft 12. Therefore, when the output shaft 12 rotates, it will cooperate with the transmission gear set 11 to drive the rotating shaft 10 to rotate. The rotating shaft 10 is installed in the groove at the bottom of the rotating seat 3, and the bottom of the rotating shaft 10 is connected to the top of the slider 2 through a bearing, so that the rotating shaft 10 can be more stable when rotating. 0 rotation can drive the rotating base 3 to rotate, the top of the rotating base 3 is connected to the camera 6 through the connecting base 4, at this time, the rotating base 3 can drive the camera 6 to rotate horizontally in the opposite direction, and at the same time, the camera 6 is connected to the connecting base 4 on the top of the rotating base 3 through the rotating shaft 5, and the rotating shaft 5 is connected to the first motor 9 through the coupling. At this time, starting the first motor 9 can rotate the rotating shaft 5, so that the rotating shaft 5 drives the camera 6 on the top to adjust the inclination angle. By adjusting the horizontal direction and the inclination angle of the camera 6, the function of multi-directional monitoring can be achieved. At the same time, cooperating with two groups of cameras 6 can avoid the situation of blind spots in monitoring.

[0036] See also Figure 1 , Figure 5 , Figure 7 and Fig. 9 It can be seen that when in use, the surrounding environment can be monitored through the red-hot external imaging sensor 7 and the induction radar module 8, and the angle of the camera 6 can be adjusted through the rotating seat 3 and the connecting seat 4, so as to achieve multi-directional monitoring of the surrounding environment.

[0037] A third motor 14 is installed inside the bracket 1 through a groove, and the output end of the third motor 14 is connected to a driving shaft 15 through a coupling. The outer side of the driving shaft 15 is sleeved with a first gear 16 and a second gear 17, and one side of the first gear 16 is meshed with a third gear 18. A driven shaft 19 is penetrated in the middle of the third gear 18, and a bevel gear set 20 is sleeved on the outer side of the driven shaft 19. The bevel gear set 20 consists of two mutually meshing bevel gears A and a bevel gear B. The bevel gear A is connected to the driven shaft 19, and a first screw rod 21 is penetrated in the middle of the bevel gear B. The first gear 16 is set on the side away from the third gear 18. There is a fourth gear 22, the middle of the fourth gear 22 is connected with a second screw rod 23, the bottom of the second gear 17 is meshed with a rack 24, the end of the drive shaft 15 is connected with a sliding block 25 through a bearing, guide blocks 35 are installed on both sides of the rack 24, the middle of the guide block 35 is connected with a guide rod 36, the outer side of the guide rod 36 is sleeved with a movable spring 37, and a movable tooth block 38 is connected between the two groups of guide rods 36. The first screw rod 21 and the second screw rod 23 are respectively threadedly connected to the slider 2 in the corresponding bracket 1 slide groove, and the sliding block 25 forms a sliding structure with the bracket 1 through the slide groove, and the bracket 1 is an "L"-shaped structure.

[0038] During specific implementation, when the monitoring device for the multi-directional monitoring area needs to adjust the position of the camera 6, the third motor 14 can be started, and the third motor 14 will drive the driving shaft 15 to rotate through the coupling. The rotation of the driving shaft 15 will drive the first gear 16 and the second gear 17 to rotate. The bottom of the second gear 17 is meshed with a rack 24. Since the rack 24 is fixedly installed in the groove of the bracket 1, and the second gear 17 rotates under the cooperation of the third motor 14 and the driving shaft 15, when the second gear 17 rotates, it will move along the rack 24, and through the driving shaft 15, the first gear 16 and the third motor 14 are moved synchronously, and at the same time, the sliding block 25 at the end of the driving shaft 15 slides along the slide groove of the bracket 1, thereby ensuring the stability of the entire driving shaft 15;

[0039] When the second gear 17 drives the first gear 16 to move in the direction of the third gear 18 through the driving shaft 15, the second gear 17 moves to one side of the rack 24. Since a movable tooth block 38 is provided on one side of the rack 24, when the second gear 17 rotates, the movable tooth block 38 will be squeezed. The movable tooth block 38 will be squeezed and move along the guide blocks 35 through the guide rods 36 on both sides, and the movable springs 37 on the outer sides of the guide rods 36 will be continuously in a compressed state. At this time, the second gear 17 will not be affected by the force of the rack 24 and will idle, so that the second gear 17 will not drive the driving shaft 15 to continue to move forward, and at the same time, the first gear 16 on the outer side of the driving shaft 15 will mesh with the third gear 18, and the third gear 18 will be meshed with each other. A driven shaft 19 is connected through it, so the driven shaft 19 will rotate with the cooperation of the first gear 16 and the third gear 18. A bevel gear set 20 is connected to one end of the driven shaft 19. The bevel gear set 20 consists of a bevel gear A and a bevel gear B. The bevel gear A is connected to the driven shaft 19. A first screw rod 21 is connected through the middle of the bevel gear B. With the cooperation of the bevel gear set 20, the first screw rod 21 can be rotated. The first screw rod 21 is threadedly connected to the slider 2, and the slider 2 is slidably connected to the slide groove of the bracket 1. Therefore, when the first screw rod 21 rotates, it can drive the slider 2 to slide along the slide groove of the bracket 1. The corresponding camera 6 can be moved by sliding the slider 2, so that the monitoring position of the camera 6 can be adjusted conveniently.

[0040] When another group of cameras 6 needs to be adjusted, the third motor 14 can drive the second gear 17 to rotate in the opposite direction. When the second gear 17 rotates in the opposite direction, the movable tooth block 38 is not squeezed by the second gear 17, and then the movable spring 37 will reset the guide rod 36 to drive the movable tooth block 38 to reset. At this time, when the second gear 17 continues to rotate, the second gear 17 will mesh with the movable tooth block 38, and the second gear 17 will rotate to the rack 24 through the movable tooth block 38, so that the rack 24 can drive the drive shaft 15, the second motor 13 and the first gear 16 to move in the opposite direction through the second gear 17, and the first gear 16 is separated from the third gear 18. The second gear 17 is connected to the fourth gear 22. When the second gear 17 is connected to the fourth gear 22, the second gear 17 will repeat the above-mentioned continuous squeezing of the movable tooth block 38 on the other side of the rack 24, so that the second gear 17 stops moving without being affected by the force of the rack 24. When the first gear 16 is connected to the fourth rack 24, the fourth gear 22 can be rotated. A second screw rod 23 is connected through the middle of the fourth gear 22. The second screw rod 23 is connected to another group of sliders 2. Through the second screw rod 23 and the slider 2, another group of cameras 6 can slide along the bracket 1, so as to facilitate the position adjustment of cameras 6 at different positions according to usage requirements to meet different usage requirements of users.

[0041] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Fig.10 It can be seen that when in use, the second gear 17 can be rotated along the rack 24, so that the driving shaft 15 drives the first gear 16 to dock with the corresponding third gear 18 or fourth gear 22, so that the position of the camera 6 at different positions can be adjusted, making it convenient for the user to quickly adjust the position of the camera 6.

[0042] A fixing frame 33 is installed on the outside of the camera 6, and a telescopic link 34 is connected to one side of the fixing frame 33 through a rotating shaft. The outside of the telescopic link 34 is connected to a tarpaulin 26 through a rotating shaft. The end of the telescopic link 34 away from the fixing frame 33 is connected to a movable frame 27 through a rotating shaft. The bottom of the telescopic link 34 is connected to a connecting block 28 through a rotating shaft. A screw sleeve 29 is installed at the bottom of the connecting block 28. A third screw rod 30 is connected through the middle of the screw sleeve 29. The input end of the third screw rod 30 is connected to a driving motor 31 through a coupling. The end of the third screw rod 30 away from the driving motor 31 is connected to a fixing block 32 through a bearing. The fixing block 32 is installed on the side of the camera 6.

[0043] During specific implementation, the monitoring device for the multi-directional monitoring area can start the driving motor 31 when it is necessary to shield the camera 6 from rain, and the output end of the driving motor 31 is connected to the third screw rod 30 through a coupling. At this time, the driving motor 31 can drive the third screw rod 30 to rotate, and the third screw rod 30 is installed on the side of the camera 6 through the fixing block 32, thereby increasing the stability of the third screw rod 30. A screw sleeve 29 is sleeved on the outer side of the third screw rod 30, and the top of the screw sleeve 29 is connected to the bottom of the telescopic connecting rod 34 through the connecting block 28 and the rotating shaft. Since the telescopic connecting rod 34 can only perform telescopic movement in the horizontal direction, the telescopic connecting rod 34 guides the connecting block 28, so that when the third screw rod 30 rotates, it will drive the screw sleeve 29 and the connecting block 28 to slide along the direction of the third screw rod 30. When the screw sleeve 29 slides, it will pull the telescopic connecting rod 34 to move through the connecting block 28 and the rotating shaft. The telescopic connecting rod 34 is composed of a plurality of connecting rods that are connected to each other. The structure is connected by a rotating shaft. When one end of the telescopic link 34 moves, the entire telescopic link 34 will be telescoped. Therefore, with the cooperation of the connecting block 28 and the screw sleeve 29, the telescopic link 34 can be rotated and unfolded. One end of the telescopic link 34 is connected to one side of the fixed block 32 through the rotating shaft. When the telescopic link 34 is unfolded, it can move in the direction of the movable frame 27, and the telescopic link 34 is connected to the tarpaulin 26 through the rotating shaft. When the telescopic link 34 is rotated and unfolded, the tarpaulin 26 can be unfolded. By unfolding the tarpaulin 26 from the top of the camera 6, the rainproof effect of the camera 6 can be increased, thereby avoiding the situation where a large amount of water droplets appear on the camera 6. Conversely, the drive motor 31 can be started in reverse, so that the drive motor 31 drives the connecting block 28 through the third screw rod 30 and the screw sleeve 29 to shrink and fold the telescopic link 34, so that the tarpaulin 26 can be pulled back onto the camera 6, and the normal use of the camera 6 will not be affected at this time.

[0044] See also Figure 3 , Figure 5 and Figure 8 It can be seen that when in use, the tarpaulin 26 on the top of the camera 6 can be unfolded through the telescopic connecting rod 34. At this time, the tarpaulin 26 can increase the rain-proof range of the camera 6, thereby making the rain-proof effect better and avoiding a large number of water droplets from adhering to the camera 6.

[0045] To sum up, when the monitoring device for the multi-directional monitoring area is in use, the entire bracket 1 can be installed on the corner of the wall by bolts, and the wires can be connected to the camera 6, and the camera 6 can be powered on at the same time so that the camera 6 can work normally. At this time, the two groups of cameras 6 can monitor the surrounding environment, and the horizontal and vertical angles of the camera 6 can be adjusted according to the monitoring needs, so as to facilitate monitoring in different directions and achieve better monitoring effects. This is the use feature of the monitoring device for the multi-directional monitoring area. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
