Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, in particular to a remote video monitoring device. Background Art

[0002] The remote monitoring device is an equipment system that integrates network, modem, wireless transmission and other technologies. It can transmit the video signal of the monitoring site to the designated monitoring center to realize remote imaging and real-time monitoring. The remote wireless digital video monitoring device is mainly composed of three parts: the front-end acquisition module, the wireless transmission link and the monitoring center. The front-end acquisition module is responsible for collecting video data, usually including high-definition cameras, video encoders and other equipment. The wireless transmission link uses wireless network technology (such as 4G, 5G, Wi-Fi, etc.) to transmit the video data processed by the front-end acquisition module to the remote monitoring center. The monitoring center receives and processes the video data from the front-end acquisition module, and restores the compressed video signal into a viewable image through the decoder.

[0003] Remote video surveillance devices are mainly used for real-time monitoring. In order to evade monitoring, conduct illegal activities or for other malicious purposes, criminals may deliberately destroy surveillance cameras. Most of the existing remote wireless digital video surveillance devices are unable to effectively protect surveillance cameras, making surveillance cameras extremely easy to damage. Many surveillance cameras have recording functions and can provide important video evidence when abnormal situations occur. Once the camera is damaged, these potential evidence materials will not be available, which will bring difficulties to subsequent investigations and evidence collection, resulting in the loss of video materials. In order to restore the monitoring function, it is necessary to purchase new cameras or repair them, which will incur additional repair and replacement costs.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention is equipped with a protective shell. When the monitoring camera is subjected to external impact, the pressure sensor detects the impact and sends a signal outward. After the electromagnet receives the impact signal, it will be powered off and lose the adsorption force on the magnetic plate. The mounting frame 1 will be released and the spring 1 will quickly push the mounting frame 1 to move upward. When the monitoring camera completely enters the protective shell, the two sets of electric telescopic rods electrically connected to the pressure sensor start to work. The output end of the electric telescopic rod pushes the baffle to move until it completely covers and blocks the opening on the protective shell through which the monitoring camera enters, so that the baffle and the protective shell can jointly form a closed protective space to provide all-round protection for the monitoring camera. The protective shell can automatically, quickly and effectively protect the monitoring camera in a very short time, thereby greatly reducing the risk of damage to the camera caused by external impact.

[0020] 2. The present invention is equipped with a reset plate, a lead screw and a first motor. As the first motor is started, the reset plate on the lead screw nut 1 outside the lead screw will move together with it. As the reset plate moves, it will push the mounting frame 1 to move downward. Under the continuous push of the reset plate, the mounting frame 1 and the monitoring camera thereon gradually return to their original positions. The magnetic plate outside the mounting frame 1 will move to a position capable of cooperating with the electromagnet. As the electromagnet is started, it will continue to fix the mounting frame 1, and the monitoring camera will be exposed to the outside again, ready to perform its monitoring task. The entire reset process realizes precise control and smooth movement of the monitoring camera, ensuring that it can quickly resume working after the emergency is resolved.

[0021] 3. The present invention is equipped with a buffer spring, a buffer plate and a buffer sponge, which can effectively absorb and disperse the impact energy when the surveillance camera is subjected to external impact and needs to be quickly pushed into the protective shell. This buffer design not only protects the surveillance camera and its mounting frame from damage, but also improves the reliability and durability of the entire protection mechanism.

[0022] 4. The present invention is installed with a shell 1. When the driving motor 1 is started, it will drive the rotating rod to rotate, and the second gear on the rotating rod will mesh with the first gear, thereby driving the screw 2 to rotate. Since the screw 2 is meshed with the screw nut 2, the screw nut 2 will make a linear motion along the axial direction of the screw 2. The first mounting frame is fixed on the screw nut 2, so it will also move with the movement of the screw nut 2, so that the nozzle on the first mounting frame can be moved to the outside of the shell 1. At the same time, the water pump will draw the flushing liquid in the water tank and transport it to the tube body through the retractable infusion tube, and finally it will be sprayed by the nozzle to the monitoring end of the monitoring camera to realize the cleaning function.

[0023] 5. The present invention is installed with a shell two. When the monitoring end of the surveillance camera is flushed and the position adjustment is completed, the height of the frame two is first adjusted by the electric telescopic column so that the wiping roller can be moved out of the shell two. Then, the driving motor two is started, which will drive the No. 2 gear to rotate. The No. 2 gear is meshed with the No. 1 gear, thereby driving the lead screw three to rotate. Since the lead screw three is meshed with the lead screw nut three, the lead screw nut three will make a linear motion along the axial direction of the lead screw three, thereby driving the second mounting frame and the wiping roller to move to the appropriate position, so that the wiping roller can contact the surface to be cleaned. Next, the driving motor three is started, which will drive the sprocket two to rotate. The sprocket two is connected to the sprocket one through a chain, so the sprocket one will also rotate, thereby driving the wiping roller to rotate. The rotation and movement of the wiping roller can achieve comprehensive cleaning of the monitoring end of the surveillance camera. BRIEF DESCRIPTION OF THE DRAWINGS

The monitoring center 2 receives the digital signal from the monitoring camera 1, stores, processes and analyzes it, and provides users with functions such as real-time monitoring images and video playback. The protective shell 3 is the monitoring The monitoring camera 1 is provided with physical protection, and the protective shell 3 is provided with fixings, the monitoring camera 1 can be installed and fixed through the protective shell 3, the monitoring camera 1 is installed on the protective shell 3 through the mounting frame 1 6 and the connecting frame 7, the pressure sensor 8 is a device that can detect physical pressure and convert it into a measurable signal, the electromagnet 5 is installed inside the protective shell 3 through the mounting frame 2 4, when the electromagnet 5 is energized, it can attract the magnetic plate 11 to fix the monitoring camera 1 on the mounting frame 6, when the monitoring camera 1 is subjected to external impact, this impact is sensed by the pressure sensor 8, the pressure sensor 8 detects the impact, it will send a signal outward, and it will be received by the electromagnet 5 electrically connected to the pressure sensor 8, and the received signal will be sent outward. After the impact signal, the electromagnet 5 will be powered off, thereby losing the attraction force on the magnetic plate 11. As the electromagnet 5 loses the attraction on the magnetic plate 11, the mounting frame 6 is released, and the spring 10 quickly pushes the mounting frame 6 to move upward. When the monitoring camera 1 completely enters the protective shell 3, the two sets of electric telescopic rods 9 electrically connected to the pressure sensor 8 start to work, and the output end of the electric telescopic rod 9 pushes the baffle 14 to move until it completely covers and blocks the opening on the protective shell 3 for the monitoring camera 1 to enter, so that the baffle 14 and the protective shell 3 can together form a closed protection space, which provides all-round protection for the monitoring camera 1, so that the protective shell 3 can automatically, quickly and effectively protect the monitoring camera 1 in a very short time.This greatly reduces the risk of damage to the camera caused by external impact.

[0037] See also Figure 4 and Figure 5 A plurality of guide rods 12 are arranged inside the protective shell 3, and a connecting piece 13 is movably arranged on the guide rod 12.

Under the continuous push of the reset plate 20, the mounting frame 6 and the monitoring camera 1 thereon gradually return to their original positions. The magnetic plate 11 outside the mounting frame 6 will move to a position where it can cooperate with the electromagnet 5.

When the mounting frame 6 is rapidly pushed by the spring 10, it will first contact the reset plate 20, and continue to move upward until it contacts the buffer spring 21 below. The buffer spring 21 will begin to compress after being impacted. This compression process is an energy conversion process. The elastic potential energy of the spring increases with the increase of the compression amount, and at the same time, it absorbs and disperses most of the impact energy generated by the upward movement of the mounting frame 6 and the surveillance camera 1. In this way, the buffer spring 21 The moving speed of the mounting frame 6 and the surveillance camera 1 is effectively slowed down, and the risk of collision between them and other components inside the protective shell 3 is reduced.

[0043] Working principle: the monitoring camera 1 is the core component of the whole system, responsible for capturing video images and converting them into digital signals, and transmitting them to the monitoring center 2 through the wireless network. The monitoring center 2 receives the digital signals from the monitoring camera 1, stores, processes and analyzes them, and provides users with functions such as real-time monitoring images and video playback. The protective shell 3 provides physical protection for the monitoring camera 1, and the protective shell 3 is provided with fixings.

The pressure sensor 8 is a device that can detect physical pressure and convert it into a measurable signal. The electromagnet 5 is installed inside the protective shell 3 through the mounting frame 2 4. When the electromagnet 5 is energized, it can attract the magnetic plate 11 to fix the surveillance camera 1 on the mounting frame 6. When the surveillance camera 1 is subjected to external impact, this impact is sensed by the pressure sensor 8. The pressure sensor 8 detects the impact and sends a signal to the outside, which is received by the electromagnet 5 electrically connected to the pressure sensor 8. After receiving the impact signal, the electromagnet 5 is powered off, thereby losing the adsorption force on the magnetic plate 11. As the electromagnet 5 loses the adsorption of the magnetic plate 11, the mounting frame 6 is released, and the spring 10 quickly pushes the mounting frame 6 to move upward. When the surveillance camera 1 completely enters the protective shell 3, the two sets of electric telescopic rods 9 electrically connected to the pressure sensor 8 start to work, and the output end of the electric telescopic rod 9 pushes the block The plate 14 moves until it completely covers and blocks the opening on the protective shell 3 through which the surveillance camera 1 enters, so that the baffle 14 and the protective shell 3 can together form a closed protective space, which provides all-round protection for the surveillance camera 1, and enables the protective shell 3 to automatically, quickly and effectively protect the surveillance camera 1 in a very short time, thereby greatly reducing the risk of damage to the camera caused by external impacts. Through the arrangement of multiple groups of guide rods 12 and connectors 13, the mounting frame 6 can be limitedly installed inside the protective shell 3. When the surveillance camera 1 enters the interior of the protective shell 3 with protection, the top of the mounting frame 6 will contact the bottom of the reset plate 20. When the surveillance camera 1 needs to be reset, the baffle 14 will first be removed from the protective shell. The opening on the body 3 through which the surveillance camera 1 enters is removed, and the first motor 17 is started. The first motor 17 starts to rotate and drives the gear 16 and the lead screw 15 to rotate through the gear 2 18. As the lead screw 15 rotates, the lead screw nut 19 meshing therewith starts to move along its axial direction. Since the lead screw nut 19 is fixedly connected to the reset plate 20, the reset plate 20 will also move therewith. As the reset plate 20 moves, it will push the mounting frame 6 to move downward. Under the continuous push of the reset plate 20, the mounting frame 6 and the surveillance camera 1 thereon gradually return to their original positions, and the magnetic plate 11 outside the mounting frame 6 will move to a position that can cooperate with the electromagnet 5. As the electromagnet 5 is started, it will continue to fix the mounting frame 6.The surveillance camera 1 is exposed to the outside again, ready to perform its surveillance task. The entire reset process achieves precise control and smooth movement of the surveillance camera 1, ensuring that it can quickly resume working after the emergency is lifted. When the mounting frame 6 is quickly pushed by the spring 10, it will first contact the reset plate 20 and continue to move upward until it contacts the buffer spring 21 below. The buffer spring 21 will begin to compress after being impacted. This compression process is an energy conversion process. The elastic potential energy of the spring increases with the increase in compression. At the same time, it absorbs and disperses most of the impact energy generated by the upward movement of the mounting frame 6 and the surveillance camera 1. In this way, the buffer spring 21 effectively slows down the mounting frame 6 and The moving speed of the surveillance camera 1 reduces the risk of collision with other components inside the protective shell 3. The buffer sponge 23 on the buffer plate 22 serves as an additional buffer layer with higher softness and elasticity. When the mounting frame 6 continues to move upward and compresses the buffer spring 21, the buffer sponge 23 will further absorb and disperse the remaining impact energy. Through the combined action of the buffer spring 21, the buffer plate 22 and the buffer sponge 23, it can effectively absorb and disperse the impact energy when the surveillance camera 1 is subjected to external impact and needs to be quickly pushed into the protective shell 3. This buffer design not only protects the surveillance camera 1 and its mounting frame 6 from damage, but also improves the reliability and durability of the entire protection mechanism. When the pressure sensor 8 is subjected to external impact, the monitoring camera 1 enters the protective shell 3 for protection. The alarm 24 electrically connected to the pressure sensor 8 will sound an alarm to the outside, and warn the operator or relevant personnel that an abnormal situation may occur and corresponding measures need to be taken. The shell 25 is the main body of the flushing mechanism, which provides a closed space to accommodate other components. The water tank 27 stores the liquid required for flushing. The frame 28 is used to support and install other components, such as the lead screw 29, the rotating rod 33, etc. The lead screw 29 is used to drive the linear motion of the first mounting frame 31 through the lead screw nut 230. The drive motor 35 provides power for the movement of the nozzle 36. The first mounting frame 31 is used to install and support the pipe body 37 and The nozzle 36 and the tube body 37 are used to transport the flushing liquid. One end of the nozzle 36 is connected to the liquid inlet end of the nozzle 36. The nozzle 36 is used to spray the flushing liquid onto the monitoring end of the monitoring camera 1 to achieve the cleaning function. The water pump 38 is fixed inside the housing 25, and its liquid inlet end extends to the inside of the water tank 27 to extract the flushing liquid in the water tank 27. The retractable infusion tube 39 is used to transport the flushing liquid during the flushing process. Since it is retractable, it can adapt to the movement of the first mounting bracket 31 during the flushing process. When the driving motor 35 is started, it will drive the rotating rod 33 to rotate, and the second gear 34 on the rotating rod 33 will mesh with the first gear 32, thereby driving the screw 29 to rotate. Since the screw 29 is meshed with the screw nut 230,Therefore, the screw nut 2 30 will make a linear motion along the axial direction of the screw 29. The first mounting frame 31 is fixed on the screw nut 2 30, so it will also move with the movement of the screw nut 2 30, so that the nozzle 36 on the first mounting frame 31 can move to the outside of the shell 1 25. At the same time, the water pump 38 will extract the flushing liquid in the water tank 27 and transport it to the tube body 37 through the retractable infusion tube 39. Finally, the nozzle 36 will spray it onto the monitoring end of the monitoring camera 1 to achieve the cleaning function. The shell 26 is the main body of the wiping mechanism, which provides a closed space to accommodate other components. The electric telescopic column 40 is used to adjust the height of the frame 2 41. The frame 2 41 is used to support and install other components, such as the screw 3 42, the drive motor 2 45, etc. The wiping roller 48 is used to clean the monitoring end of the monitoring camera 1. When the monitoring end of the monitoring camera 1 is flushed and the position is completed During adjustment, firstly, the height of the frame body 2 41 is adjusted by the electric telescopic column 40 so that the wiping roller 48 can be moved out of the housing 2 26 , and then, the driving motor 2 45 is started, which will drive the second gear 46 to rotate, and the second gear 46 is meshed with the first gear 44, thereby driving the lead screw 3 42 to rotate. Since the lead screw 3 42 is meshed with the lead screw nut 3 43, the lead screw nut 3 43 will make a linear motion along the axis direction of the lead screw 3 42, thereby driving the second mounting frame 47 and the wiping roller 48 to move to the appropriate position, so that the wiping roller 48 can contact the surface to be cleaned, and then, the driving motor 3 50 is started, which will drive the sprocket 2 51 to rotate, and the sprocket 2 51 is connected to the sprocket 1 49 through the chain 52, so the sprocket 1 49 will also rotate, thereby driving the wiping roller 48 to rotate, and the rotation and movement of the wiping roller 48 can achieve comprehensive cleaning of the monitoring end of the surveillance camera 1.
