Description

Technical Field

[0001] This utility model relates to the field of video surveillance facilities technology, and in particular to a behavior recognition device for video surveillance. Background Technology

[0002] With the rapid development of deep learning, artificial intelligence and computer vision technologies, significant progress has been made in behavior recognition and target tracking technologies in video surveillance systems. These technologies can automatically extract spatial and temporal features from videos and train on large-scale datasets, improving the accuracy and robustness of behavior recognition.

[0003] In existing technologies, traditional video surveillance behavior recognition devices typically use bolts to fasten the sealed housing together. This bolt-fastening design means that every time internal components need to be inspected or replaced, tools must be used to loosen and retighten the bolts. This process is not only time-consuming but also cumbersome for operators. Especially in emergencies, such as when equipment malfunctions require immediate repair, this design may delay problem-solving and affect the normal operation of the entire monitoring system. Frequent disassembly and installation of bolts may cause thread wear or damage, thereby reducing the reliability of the connection. Over time, this wear may become more severe, leading to bolt stripping and making replacement difficult. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a behavior recognition device for video surveillance.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a video surveillance behavior recognition device, comprising a device base, a connecting rod slidably connected inside the device base, a detection housing rotatably connected to the front end of the connecting rod, a detection camera electrically connected inside the detection housing, a sealing plate detachably connected to the bottom of the detection housing, a fixing rod fixed inside the detection housing, a fixing base fixed to the bottom of the sealing plate, a sliding ring slidably connected inside the fixing base, a support spring fixed to the bottom of the sliding ring, the top end of the support spring fixedly connected to the inside of the fixing base, a limiting inner ring fixed inside the fixing base, a sliding connection between the inside of the fixing base and the surface of the fixing rod, a limiting bead slidably connected inside the limiting inner ring, and an arc groove formed on the circumferential surface of the fixing rod.

[0006] Preferably, a limiting plate is slidably connected inside the device base, and the limiting plate is fixedly connected to a connecting rod. A damping sleeve is fixed inside the device base, and the inner wall of the damping sleeve is slidably connected to the circumferential surface of the connecting rod. A shock-absorbing spring is fixed to the surface of the limiting plate, and the side end of the shock-absorbing spring is fixedly connected to the inner wall of the device base. A damping air rod is fixed to the side wall of the limiting plate, and the side end of the damping air rod is fixedly connected to the inner wall of the device base. A thrust spring is fixed inside the damping sleeve, and a sealing ball is fixed to the upper end of the thrust spring. A ventilation channel is provided inside the damping sleeve. In the prior art, when traditional video surveillance behavior recognition devices are installed at a low position, they are susceptible to external impacts. Since these devices are generally fixed by rigid connections, they are easily damaged by external impacts or collisions. This design flaw not only affects the stability and reliability of the monitoring system, but also increases maintenance costs and frequency. When the behavior recognition device is located near the ground or at a height easily accessible to people, it faces the risk of being accidentally kicked or bumped. In addition, malicious acts may target these low-lying devices, further increasing security risks. To address these issues, this invention employs a shock-absorbing device. When the device is subjected to external impact, the connecting rod compresses into the damping sleeve, while the limiting plate compresses the damping spring. Simultaneously, the air pressure inside the damping sleeve compresses the sealing ball, causing it to move downwards. When the damping spring recovers, the air pressure pushes the sealing ball against the ventilation channel, reducing the gas flow rate and decreasing the recovery rate of the damping spring. This reduces the possibility of the device being damaged by external impacts, thereby improving the stability and reliability of the device.

[0007] Preferably, the sealing plate is installed at the bottom of the device base, thereby reducing the entry of moisture in rainy weather and further improving the stability of the device.

[0008] Preferably, the damping sleeve has an air groove on its circumference. The air groove accelerates gas exchange, thereby quickly converting the external impact into the potential energy of the damping spring, further reducing the damage caused by the external impact to the device.

[0009] Preferably, the damping spring is a double-strand spring. Due to the structure of two springs connected in parallel, the double-strand spring can effectively distribute the force and improve the overall stability. Compared with a single-strand spring, the double-strand spring can better maintain its shape and position when subjected to external impact, thus reducing equipment vibration.

[0010] Preferably, the bottom array of the damping sleeve has vent holes. By setting vent holes at the bottom of the damping sleeve, air inside the sleeve can be effectively removed, reducing the interference of air on the damping process, thereby improving the stability and response speed of the damper.

[0011] Preferably, the sliding ring has anti-slip texture on its circumferential surface. The anti-slip texture design enables the sliding ring to maintain good performance in different environments. In humid or rainy environments, the anti-slip texture can repel moisture and reduce slippage; in dry or dusty environments, the anti-slip texture can increase friction and prevent slippage.

[0012] Beneficial effects

[0013] 1. In existing technologies, traditional video surveillance behavior recognition devices typically use bolts to secure the sealed housing together. This bolt-fastening design means that every time internal components need to be inspected or replaced, tools must be used to loosen and retighten the bolts. This process is not only time-consuming but also cumbersome for operators. Especially in emergencies, such as when equipment malfunctions require immediate repair, this design may delay problem-solving and affect the normal operation of the entire monitoring system. Frequent disassembly and installation of bolts may cause thread wear or damage, thereby reducing the reliability of the connection. Over time, this wear may... This can worsen the problem, leading to stripped bolts and difficulty in replacement. To address this issue, this invention employs a disassembly structure. When maintenance or upgrades the identification device, the user simply presses the sliding ring to disengage the limiting bead from the arc groove on the surface of the fixing rod. The user can then use the fixing base to detach the sealing plate along the fixing rod. After maintenance, the user pushes the sealing plate back in along the fixing rod until the limiting bead reaches the arc groove. The user then releases the sliding ring, and the support spring pushes the sliding ring to position the limiting bead in the arc groove, thus completing the installation. This improves the ease of device maintenance and enhances the user experience.

[0014] 2. In existing technologies, traditional video surveillance behavior recognition devices are installed at low positions, making them susceptible to external impacts. Since these devices are typically fixed with rigid connections, they are easily damaged by external impacts or collisions. This design flaw not only affects the stability and reliability of the monitoring system but also increases maintenance costs and frequency. When behavior recognition devices are located near the ground or at easily accessible heights, they face the risk of being accidentally kicked or bumped. Furthermore, malicious acts may target these low-lying devices, further increasing security risks. To address these issues, this invention employs a shock-absorbing device. When the device is subjected to external impact, the connecting rod compresses into the damping sleeve, while the limiting plate compresses the damping spring. Simultaneously, the air pressure inside the damping sleeve compresses the sealing ball, causing it to move downwards. Afterwards, when the damping spring recovers, the air pressure pushes the sealing ball against the ventilation channel, reducing the gas flow rate and decreasing the spring's recovery rate, thereby reducing the likelihood of damage from external impacts and improving the device's stability and reliability.

The inside of the fixed base 201 is slidably connected to the surface of the fixed rod 2. A limiting bead 205 is slidably connected inside the limiting inner ring 204. An arc groove is formed on the circumference of the fixed rod 2. In existing technologies, traditional video surveillance behavior recognition devices typically use bolts to fix the sealing shell together. This bolt-fixing design means that every time internal components need to be inspected or replaced, tools must be used to loosen and retighten the bolts, a process that is not only time-consuming... The traditional design is lengthy and cumbersome for operators, especially in emergencies such as equipment malfunctions requiring immediate repair. This design can delay problem-solving and affect the normal operation of the entire monitoring system. Frequent disassembly and installation of bolts can lead to thread wear or damage, reducing the reliability of the connection.

The user then releases the sliding ring 202, and the support spring 203 pushes the sliding ring 202 to push the limiting bead 205 into the arc groove position for locking, thus completing the installation. This improves the ease of device maintenance and enhances the user experience.

Then, the user can use the fixing base 201 to disengage the sealing plate 104 along the fixing rod 2. After the staff finishes maintaining the identification device, the staff pushes the sealing plate 104 along the fixing rod 2 until the limiting bead 205 reaches the arc groove position.
