Technical Field

[0001] This invention relates to the field of video surveillance technology, specifically to a portable mobile video surveillance device. Background Technology

[0002] With the development and popularization of IoT technology, intelligent security monitoring systems have become an indispensable part of modern society. By combining IoT technology with traditional monitoring devices, users can obtain images captured by the monitoring devices in real time on terminal devices such as mobile phones or computers. They can also wirelessly control the monitoring devices to adjust the monitoring angle and change the monitoring perspective, helping people to monitor the places they need in real time and meet their security needs.

[0003] Publication No. CN209345294U discloses a novel handheld mobile video monitoring device. This modern, intelligent handheld terminal video monitoring device has been applied in power company marketing operations, including customer service, business expansion and maintenance, meter reading management, fee collection, marketing auditing, and customer management. The handheld terminal not only improves the efficiency and quality of marketing work but also enhances the informatization level of power companies in marketing, achieving digital management. Publication No. CN219611888U discloses a video monitoring device for substations, including a connecting base for installing and fixing the video monitoring device; a telescopic rod connected to the bottom of the connecting base for adjusting the position of the video monitoring device; and the main body of the video monitoring device, located below the telescopic rod, for video monitoring within the substation. The addition of a telescopic structure allows the video monitoring device to be adjusted as needed, changing its space occupancy and greatly ensuring space utilization. Furthermore, a backup power supply is provided in the main body of the video monitoring device to meet the needs of real-time video monitoring. However, this patent still has the following problems in practical use:

[0004] Although the video surveillance device for this substation can be adjusted as needed via a telescopic structure, its fixed location means that even with multi-directional adjustments, blind spots remain, leading to missed areas. Furthermore, the device cannot be disassembled or moved by hand. When handheld video surveillance is required, a handheld camera must be used, resulting in limited functionality and impacting the effectiveness of the surveillance camera.

[0005] Therefore, a portable mobile video surveillance device is proposed to solve the problems mentioned above. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This portable mobile video monitoring device, under the action of the inclined groove inside the mounting threaded sleeve, squeezes the unlocking sliding rod, causing the unlocking sliding rod to move the mounting sliding sleeve and the mounting limiting block inwards. Simultaneously, the mounting sliding sleeve drives the mounting pin to move. When the mounting pin separates from the mounting cover, the entire monitoring device can be disassembled from inside the mounting cover for handheld monitoring. By continuing to rotate the mounting threaded sleeve and squeeze the unlocking sliding rod, the clamping connecting rods on both sides move, simultaneously driving the clamping rotating rod to rotate. Under the action of the rotating support, the clamping claws can rotate, thus using the clamping claws to clamp objects or tools, facilitating the fixing of the monitoring device in one place and freeing workers' hands for monitoring operations. By expanding the adjustment range of the camera body, the monitoring range of the camera body is improved. The specific details are as follows:

[0022] 1. By setting up a monitoring disassembly mechanism, when it is necessary to disassemble the monitoring device, by grasping the monitoring housing and rotating the installation threaded sleeve, the inclined groove inside the installation threaded sleeve squeezes the unlocking sliding rod, causing the unlocking sliding rod to move the installation sliding sleeve and the installation limit block inward. At the same time, the installation sliding sleeve moves the installation pin. When the installation pin separates from the installation cover, the entire monitoring device can be disassembled from the inside of the installation cover. The monitoring operation can be carried out by hand. By continuing to rotate the installation threaded sleeve and squeeze the unlocking sliding rod, the clamping connecting rods on both sides move and drive the clamping rotating rod to rotate. Under the action of the rotating support, the clamping claw can rotate, thereby using the clamping claw to clamp objects or tools, making it easy to fix the monitoring device in one place, allowing workers to free their hands for monitoring operations. When the internal temperature of the camera body is high, the two cooling fans are activated. The system consists of two cooling fans: one for exhaust and the other for exhaust. The airflow from the cooling fans circulates within the protective housing, aided by an arc-shaped plate and a heat dissipation guide plate, and is then exhausted through ventilation holes, thus improving the heat dissipation of the camera body. Starting the first rotating motor drives the rotating connecting shaft and rotating gear. Utilizing the meshing connection between the rotating gear and the meshing gear ring, the meshing gear ring rotates the camera body, adjusting its angle and increasing its monitoring range. Simultaneously, the rotating connecting shaft drives the first linkage gear. The transmission connection between the first linkage gear, the transmission belt, and the second linkage gear drives the cleaning scraper, cleaning the surface of the protective housing. Cleaning the surface of the protective housing first improves the image clarity of the camera body.

[0023] 2. By setting up a lifting and adjusting mechanism, not only can the adjusting motor drive the adjusting threaded rod to rotate, causing the adjusting threaded sleeve to move on the outside of the adjusting threaded rod, but it can also drive the adjusting rotating rod to rotate, realizing the vertical rotation of the adjusting plate and the fixed plate. This allows for the adjustment of the vertical angle of the monitoring device. Simultaneously, starting the second rotating motor drives the rotating worm gear to rotate. Utilizing the meshing connection between the rotating worm gear and the rotating worm wheel, the longitudinal angle of the monitoring device can be adjusted. Combined with the rotation of the camera body driven by the first rotating motor, the adjustment range of the camera body can be expanded, thereby improving the monitoring range of the camera body. By starting the fixing bolts, the mounting plate can be fixed, facilitating the installation of the lifting I-beam in the designated position. At the same time, the bidirectional lifting motor can be activated. The machine drives the sprocket transmission assembly and the lifting gear to rotate. Utilizing the meshing connection between the lifting gear and the meshing rack, the height of the monitoring device can be adjusted, which not only increases the monitoring range of the device but also facilitates its handling and movement. The elastic force of the compression spring enables the movement of the compression sliding sleeve. Under the action of the compression bracket and the compression rotating rod, the compression roller and the lifting I-beam can be internally fitted together. At the same time, the spring-limiting roller limits the lifting bracket, thereby improving the lifting stability of the lifting bracket. The self-locking function of the bidirectional lifting motor enables the fixing of the lifting bracket. The bidirectional lifting motor adopts a bidirectional servo motor and uses the built-in mechanical structure and intelligent control system to achieve the self-locking function.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-5The present invention provides a technical solution: a portable mobile video surveillance device, including a monitoring disassembly mechanism 1 and a mounting bracket 103 installed on one side of the monitoring disassembly mechanism 1.

The monitoring disassembly mechanism 1 includes a mounting cover 101, and a through groove 102 is opened at the center of the interior of the mounting cover 101. A mounting sliding rod 104 is fixedly installed around the interior of the mounting bracket 103. A mounting sliding sleeve 105 is slidably connected to the outer side of the mounting sliding rod 104, and a mounting sliding sleeve 105 is fixedly installed on the outer side of the mounting sliding sleeve 105. A mounting limit block 106 is provided, wherein a mounting pin 107 is fixedly mounted on one side of the mounting limit block 106, and an unlocking sliding rod 108 is fixedly mounted on the side of the mounting sliding sleeve 105 away from the mounting limit block 106, wherein a return spring 109 is fixedly mounted on one side of the mounting sliding sleeve 105. Clamping connecting rods 110 are fixedly mounted on the sides of the mounting limit blocks 106 away from the mounting pins 107 on both sides. A clamping rotating rod 111 is rotatably connected to the end of the clamping connecting rod 110, and a clamping claw 112 is rotatably connected to the end of the clamping rotating rod 111.

The outer side of the mounting bracket 103 is threadedly connected to the mounting threaded sleeve 114. The mounting threaded sleeve 114 has an inclined groove 115 inside, which fits against the end of the unlocking sliding rod 108. When it is necessary to disassemble the monitoring device, by holding the monitoring housing 116 and rotating the mounting threaded sleeve 114, the inclined groove 115 inside the mounting threaded sleeve 114 squeezes the unlocking sliding rod 108, causing the unlocking sliding rod 108 to drive the mounting sliding sleeve 105 and the mounting limit block 106 to move inward. At the same time, the mounting sliding sleeve 105... 5. Move the mounting pin 107. When the mounting pin 107 separates from the mounting cover 101, the entire monitoring device can be disassembled from the inside of the mounting cover 101 and moved for monitoring by hand. By continuing to rotate the mounting threaded sleeve 114 and squeezing the unlocking sliding rod 108, the clamping connecting rods 110 on both sides move and drive the clamping rotating rod 111 to rotate. Under the action of the rotating support 113, the clamping claw 112 can be rotated, so that the clamping claw 112 can be used to clamp objects or tools, making it easy to fix the monitoring device in one place and freeing the workers' hands to carry out monitoring operations.

Heat dissipation guide plates 124 are fixedly installed on the surface of the arc-shaped plates 123. When the internal temperature of the camera body 129 is high, two heat dissipation fans 120 are activated. One heat dissipation fan 120 draws air in and the other heat dissipation fan 120 exhausts air. Under the action of the arc-shaped plates 123 and the heat dissipation guide plates 124, the air blown out by the heat dissipation fans 120 can circulate inside the monitoring protective cover 117 and be discharged through the heat dissipation holes 119, thereby improving the heat dissipation effect of the camera body 129.

[0039] Please see Figures 6-7 A first rotating motor 125 is fixedly installed on one side of the inside of the monitoring housing 116. A rotating connecting shaft 126 is fixedly connected to the output end of the first rotating motor 125. Rotating gears 127 are fixedly installed at both ends of the rotating connecting shaft 126. Meshing gear rings 128 are meshed on one side of each of the two rotating gears 127. A camera body 129 is fixedly installed inside the two meshing gear rings 128. A first linkage gear 130 is fixedly installed at one end of the rotating connecting shaft 126. A transmission belt 131 is driven to the outside of the first linkage gear 130. A second linkage gear 132 is driven to the inside of the transmission belt 131 on the side away from the first linkage gear 130. A cleaning scraper 133 is fixedly installed on the inside of the second linkage gear 132. The cleaning scraper 133 is rotatably connected to the camera body 129. Next, by starting the first rotating motor 125, the rotating connecting shaft 126 and the rotating gear 127 are driven to rotate. Utilizing the meshing connection between the rotating gear 127 and the meshing gear ring 128, the meshing gear ring 128 can drive the camera body 129 to rotate, thereby adjusting the angle of the camera body 129 and increasing the monitoring range of the camera body 129. At the same time, the rotating connecting shaft 126 drives the first linkage gear 130 to rotate. Utilizing the transmission connection between the first linkage gear 130, the transmission belt 131, and the second linkage gear 132, the second linkage gear 132 drives the cleaning scraper 133 to rotate, which can clean the surface of the monitoring protective cover 117. By cleaning the surface of the monitoring protective cover 117 first, the image clarity of the camera body 129 is improved.

[0040] Please see Figure 1 , Figures 7-9The lifting and adjusting mechanism 2 includes an adjusting bracket 201, with reinforcing brackets 202 fixedly installed on both sides of the adjusting bracket 201.

The bottom of the rotating worm gear 211 is meshed with a rotating worm wheel 212. The adjusting motor 203 drives the adjusting threaded rod 204 to rotate, so that the adjusting threaded sleeve 205 moves on the outside of the adjusting threaded rod 204 and drives the adjusting rotating rod 206 to rotate. This enables the vertical rotation of the adjusting plate 207 and the fixed plate 208, and can adjust the vertical angle of the monitoring device. At the same time, the second rotating motor 210 is started to drive the rotating worm gear 211 to rotate. Utilizing the meshing connection between the rotating worm gear 211 and the rotating worm wheel 212, the longitudinal angle of the monitoring device can be adjusted. In conjunction with the rotation of the camera body 129 driven by the first rotating motor 125, the adjustment range of the camera body 129 can be expanded, thereby improving the monitoring range of the camera body 129.

The bottom of the pressing bracket 225 is rotatably connected to... A clamping rotating rod 226 is rotatably connected to a lifting bracket 217. A clamping roller 227 is fixedly installed at the end of the clamping bracket 225.

The mounting plate 213 can be fixed by starting the fixing bolt 214, facilitating the installation of the lifting I-beam 215 to the designated position. Simultaneously, the bidirectional lifting motor 218 is started, driving the sprocket transmission assembly 219 and the lifting gear 221 to rotate. Utilizing the meshing connection between the lifting gear 221 and the meshing rack 216, the height of the monitoring device can be adjusted, not only increasing the monitoring range of the device, but also... The device is easy to handle and move, and the pressure spring 224 allows the sliding sleeve 223 to move. Under the action of the pressure bracket 225 and the pressure rotating rod 226, the pressure roller 227 can be internally fitted to the lifting I-beam 215. At the same time, the spring limiting roller 228 limits the lifting bracket 217, thereby improving the lifting stability of the lifting bracket 217. The self-locking function of the bidirectional lifting motor 218 can fix the lifting bracket 217. The bidirectional lifting motor 218 adopts a bidirectional servo motor and uses the built-in mechanical structure and intelligent control system to achieve the self-locking function.

[0042] Working principle: Before using this portable mobile video surveillance device, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 11As shown, firstly, when it is necessary to disassemble the monitoring device, by holding the monitoring housing 116 and rotating the mounting threaded sleeve 114, the unlocking sliding rod 108 is squeezed by the inclined groove 115 inside the mounting threaded sleeve 114. This causes the unlocking sliding rod 108 to move the mounting sliding sleeve 105 and the mounting limit block 106 inward. At the same time, the mounting sliding sleeve 105 moves the mounting pin 107. When the mounting pin 107 separates from the mounting cover 101, the entire monitoring device can be disassembled from the inside of the mounting cover 101. The monitoring operation can be performed by hand. By continuing to rotate the mounting threaded sleeve 114 and squeeze the unlocking sliding rod 108, the clamping connecting rods 110 on both sides move and drive the clamping rotating rod 111 to rotate. Under the action of the rotating support 113, the clamping claw 112 can be rotated. Thus, the clamping claw 112 can be used to clamp objects or tools, making it easy to fix the monitoring device in one place and freeing the workers' hands to perform monitoring operations.

[0043] Secondly, when the internal temperature of the camera body 129 is high, two cooling fans 120 are activated. One cooling fan 120 draws in air, and the other exhausts air. Under the action of the arc plate 123 and the heat dissipation guide plate 124, the air blown out by the cooling fans 120 can circulate inside the monitoring protective cover 117 and be discharged through the heat dissipation holes 119, thereby improving the heat dissipation effect of the camera body 129. The first rotating motor 125 is activated to drive the rotating connecting shaft 126 and the rotating gear 127 to rotate, and the rotating gear 127 is connected by meshing with the meshing gear ring 128. The features of the meshing gear ring 128 enable the camera body 129 to rotate, thereby adjusting the angle of the camera body 129 and improving the monitoring range of the camera body 129. At the same time, the rotating connecting shaft 126 drives the first linkage gear 130 to rotate. Utilizing the transmission connection between the first linkage gear 130, the transmission belt 131, and the second linkage gear 132, the second linkage gear 132 drives the cleaning scraper 133 to rotate, which can clean the surface of the monitoring protective cover 117. By cleaning the surface of the monitoring protective cover 117 first, the image clarity of the camera body 129 is improved.

[0044] Finally, the adjusting motor 203 drives the adjusting threaded rod 204 to rotate, causing the adjusting threaded sleeve 205 to move outward on the adjusting threaded rod 204, which in turn drives the adjusting rotating rod 206 to rotate. This enables the vertical rotation of the adjusting plate 207 and the fixed plate 208, allowing adjustment of the vertical angle of the monitoring device. Simultaneously, the second rotating motor 210 is activated, driving the rotating worm gear 211 to rotate. Utilizing the meshing connection between the rotating worm gear 211 and the rotating worm wheel 212, the longitudinal angle of the monitoring device can be adjusted. Combined with the rotation of the camera body 129 driven by the first rotating motor 125, the adjustment range of the camera body 129 can be expanded, thereby improving the monitoring range of the camera body 129. By activating the fixing bolt 214, the mounting plate 213 can be fixed, facilitating the installation of the lifting I-beam 215 to the designated position. At the same time, the bidirectional lifting motor 218 is activated... The rotating sprocket drive assembly 219 and the lifting gear 221, utilizing the meshing connection between the lifting gear 221 and the meshing rack 216, enable height adjustment of the monitoring device. This not only increases the monitoring range of the device but also facilitates its handling and movement. The elastic force of the compression spring 224 allows the movement of the compression sliding sleeve 223. Under the action of the compression bracket 225 and the compression rotating rod 226, the compression roller 227 and the lifting I-beam 215 are internally fitted together. Simultaneously, the spring-limiting roller 228 limits the lifting bracket 217, thereby improving its lifting stability. The self-locking function of the bidirectional lifting motor 218 enables the fixing of the lifting bracket 217. The bidirectional lifting motor 218 is a bidirectional servo motor that utilizes a built-in mechanical structure and intelligent control system to achieve the self-locking function.
