DETAILED DESCRIPTION

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 7 As shown, an embodiment of the present invention provides an intelligent security alarm device based on a smart park, including an alarm 1 and a security device 4. The alarm 1 is fixedly installed on the upper end of the adjustment mechanism 3, and the security device 4 is fixedly installed on the lower end of the adjustment mechanism 3. The security device 4 is provided with a sensor module, a data processing unit, a data acquisition unit, a communication unit, a storage unit and a power supply unit, and a dust removal mechanism 2 is provided on one side of the adjustment mechanism 3.

[0027] Specifically, the sensor module detects abnormal data in the environment and transmits the data to the data processing unit. The data processing unit analyzes and processes the received data and sends instructions to the alarm unit when it is determined that an abnormality exists. The image acquisition unit is a monitoring camera, which is used to obtain image information of the monitored area in real time and transmit it to the data processing unit for analysis. The communication unit is used to transmit the alarm information and related data to the remote control center or the receiving device of the designated personnel. The alarm unit sends an audible and visual alarm signal after receiving the instruction from the data processing unit. The storage unit is used to store monitoring data and alarm records. The power supply unit provides a stable power supply for the entire device. The modules and units cooperate with each other to complete the intelligent security work of the smart park.

[0028] Furthermore, the adjustment mechanism 3 includes an installation box 31, a motor 32 is fixedly installed at one end of the installation box 31, a lead screw 33 is rotatably installed in the installation box 31, one end of the lead screw 33 is fixedly connected to the output end of the motor 32, and movable blocks 34 are threadedly sleeved on the rod bodies at both ends of the lead screw 33, and the movable block 34 is slidably connected to the inner wall of the installation box 31. A transmission assembly 35 is arranged in the middle of the lead screw 33, and the transmission assembly 35 includes a worm 351 and a worm wheel 352. The worm 351 is fixedly sleeved in the middle of the lead screw 33. The worm gear 352 is meshedly connected to the upper part of the worm 351, and the bottom of the movable block 34 is fixedly connected to the support rod 36. The bottom of the support rod 36 is integrated with a limit plate 361, and the lower surface of the limit plate 361 abuts on the adjustment frame 38. A fastening screw 37 is movably provided inside the adjustment frame 38, and the fastening screw 37 is threadedly inserted into the bottom of the support rod 36. One end of the adjustment frame 38 is fixedly connected to the mounting frame 39, and the end of the mounting frame 39 away from the adjustment frame 38 is fixedly connected to the upper surface of the shell of the security device 4.

[0029] Specifically, the connecting rod 23 is arranged vertically to the lead screw 33. By setting the transmission assembly 35, the transmission direction can be changed so that the connecting rod 23 rotates along with the lead screw 33, and the movement of the security equipment 4 and the cleaning of the camera lens can be realized at the same time. A large transmission ratio can also be achieved, and more precise and significant motion adjustment can be achieved. The self-locking structure of the transmission assembly 35 can improve the stability of the connecting rod 23.

[0030] During the specific setting, the screw 33 is driven to rotate by the installation box 31, and the movable blocks 34 and the screw 33 cooperate with each other, so that the movable blocks 34 at both ends move left or right along the screw 33 at the same time, thereby driving the support rod 36 to move synchronously, and the support rod 36 is fixed to the adjustment frame 38 by fastening the screw 37, so that the support rod 36 drives the adjustment frame 38 and the security device 4 to move synchronously, thereby realizing the adjustment of the position of the security device 4.

[0031] Through the above technical solution, the position of the security device 4 can be adjusted after the equipment is installed, and the range of monitoring and shooting can be flexibly changed to cover a wider area and reduce monitoring blind spots. It can also prevent the security device 4 from being blocked, ensuring that the target is always within the monitoring range, thereby improving the effectiveness of monitoring.

[0032] In the specific setting, the adjustment frame 38 is hollow, and the middle part of the fastening screw 37 is located in the middle part of the adjustment frame 38. By making the fastening screw 37 and the bottom threaded connection of the support rod 36 tightly, the fastening screw 37 and the limit plate 361 clamp the adjustment frame 38, thereby realizing the connection between the support rod 36 and the adjustment frame 38. In order to further improve the adjustment range of the security equipment 4, the adjustment frame 38 is connected to the support rod 36. By adjusting the relative position of the support rod 36 and the adjustment frame 38, the position of the security equipment 4 is changed, so that when the driving adjustment mechanism 3 is used to adjust the security equipment 4, the adjustment range is changed to meet the use requirements in various environments.

[0033] Furthermore, the dust removal mechanism 2 includes a connecting rod 23, which is fixedly sleeved in the worm gear 352. One end of the connecting rod 23 is rotatably connected to the side wall of the mounting box 31, and the other end is fixedly installed with a mounting plate 21 through a fastener 24. A fixing frame 22 is provided on one side of the mounting plate 21, and both ends of the fixing frame 22 are fixedly connected to the outer wall of the mounting box 31. The first scraper strip 211 and the second scraper strip 221 are detachably installed on the side where the mounting plate 21 and the fixing frame 22 are close, and through holes 212 are provided at both ends of the mounting plate 21.

[0034] Specifically, the first scraper strip 211 abuts against the lens surface, the aperture of the through hole 212 is larger than the diameter of the lens, the first scraper strip 211 is made of silicone or other flexible materials, and is used to remove dust from the lens surface while ensuring that the lens surface is not damaged. During the rotation of the first scraper strip 211, it will contact the second scraper strip 221. Through the contact between the two, the dust on the first scraper strip 211 can be scraped off to avoid secondary pollution to the lens, and automatic cleaning is also achieved. In addition, the second scraper strip 221 and the first scraper strip 211 can be disassembled to facilitate subsequent cleaning or replacement.

[0035] During the specific setting, the mounting plate 21 rotates synchronously with the connecting rod 23, the position of the fixing frame 22 is fixed, and the mounting plate 21 is driven to rotate by the transmission assembly 35. During the rotation process, the mounting plate 21 scrapes the dust on the surface of the lens through the first scraper 211 to achieve automatic dust removal and ensure the clarity of the monitoring image. When the first scraper 211 rotates past the second scraper 221, the dust attached to it is cleaned off to avoid the situation where the scraping becomes dirtier.

[0036] In addition, in stormy and snowy weather, by setting the mounting plate 21 in front of the security equipment 4, on the one hand, it can limit the security equipment 4 and improve the stability of the security equipment 4, and on the other hand, it can prevent the security equipment 4 from being hit by objects. The through hole 212 opened on the mounting plate 21 can also ensure that the equipment can capture the scene normally, helping the staff to grasp the situation on the scene, especially in harsh environments.

[0037] Working principle of the present invention:

[0038] During use, if the position of the security device 4 needs to be adjusted, the starting motor 32 drives the lead screw 33 to rotate, so that the two movable blocks 34 slide in the same direction along the inner wall of the installation box 31, thereby making the security device 4 move synchronously. During this process, the lead screw 33 drives the connecting rod 23 to rotate through the transmission assembly 35, thereby making the mounting plate 21 rotate. During the rotation process, the first scraper 211 scrapes off the dust on the surface of the camera lens to ensure the clarity of the monitoring image. The first scraper 211 then rotates to the second scraper 221, and the dust on the first scraper 211 is intercepted by the second scraper 221 to achieve automatic cleaning and avoid secondary pollution to the lens. In stormy and snowy weather, the mounting plate 21 is blocked in front of the security device 4 to improve the stability of the security device 4, avoid impact, and ensure the normal operation of the equipment.

[0039] To sum up: this kind of intelligent security alarm device based on the smart park, by connecting the security equipment 4 to the adjustment mechanism 3, can adjust the position of the security equipment 4 after the equipment is installed, flexibly change the range of monitoring and shooting, so as to cover a wider area, reduce the monitoring blind spot, and avoid the security equipment 4 from being blocked, ensure that the target is always within the monitoring range, and improve the effectiveness of monitoring. By setting up the dust removal mechanism 2, when it rotates with the adjustment mechanism 3, it can remove dust from the security equipment 4 and ensure the clarity of the monitoring picture. In stormy and snowy weather, the mounting plate 21 blocks the security equipment 4, which can improve the stability of the security equipment 4, avoid impact, and ensure the normal operation of the equipment.
