Abstract
Description
Technical Field
[0001] This invention relates to the field of outdoor monitoring technology, and in particular to a video surveillance camera and a video surveillance system. Background Technology
[0002] The existing wiring structure at the tail end of the outdoor monitoring camera for water quality monitoring users makes it easy for the two types of cables to become tangled and stacked during installation and wiring. The power cord will continuously generate heat during operation, and the tangled and stacked cables will greatly hinder the heat dissipation, causing localized and continuous high temperatures in the cables. Long-term high temperature environment will accelerate the aging and cracking of the cable insulation layer, and significantly shorten the service life of the circuit and the internal components of the camera.
[0003] Meanwhile, water quality monitoring areas such as rivers and lakes are often humid and foggy. Outdoor scenes are easily affected by factors such as lightning, aging lines, and water ingress. If there is a lot of tangling between the power cord and data transmission line when the camera is installed, the heat dissipation effect will be poor. This will not only accelerate the aging of the line, but also make it difficult to dissipate heat in time. There is a risk of short circuit or spontaneous combustion. In case of sudden accidents, the data line will be burned in a very short time, and sometimes the critical images cannot be stored and transmitted in time. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a video surveillance camera and video surveillance system to solve the problems of poor heat dissipation efficiency of existing outdoor cameras, difficulty in timely dissipation of heat accumulated at the wiring points, risk of short circuits or spontaneous combustion, data cables being burned in a very short time, and sometimes critical images not being stored and transmitted in a timely manner.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a video surveillance camera, comprising a video surveillance device, a camera module housed inside the front end of the video surveillance device, side heat dissipation holes on both sides of the video surveillance device, a mounting bracket at the bottom of the video surveillance device, a honeycomb sound insulation panel installed on the inner wall of the video surveillance device, and a power cord and a data transmission line installed at the end of the camera module; an adjustable heat dissipation and sealing component installed inside the rear end of the video surveillance device, the adjustable heat dissipation and sealing component being used to dissipate heat from the camera module using natural wind; and a wire end protection component inserted into the outer wall of the rear end of the video surveillance device, the wire end protection component being used to protect the ends of the power cord and the data transmission line.
[0006] Optionally, the power lines are configured in two sets, and the data transmission line is positioned between the two sets of power lines.
[0007] Optionally, the adjustable heat dissipation and sealing assembly includes an air duct, which is disposed on the inner wall of the video surveillance equipment. An air collection plate is installed on the side wall of the air duct, and an air inlet is provided at the bottom of the air collection plate. An air guide plate is disposed on the inner side of the air collection plate, and an air guide strip is installed on the outer wall of the air guide plate.
[0008] Optionally, the air collection plate is V-shaped, the air guide plate is arc-shaped and positioned close to the bottom of the air collection plate, and the number of air collection plates and air guide plates is set to multiple sets, and they are installed around the side wall of the air guide tube.
[0009] Optionally, the air guide tube is sleeved on the outer surface of the camera module, the tail end of the camera module is provided with a mounting chuck, a sleeve is inserted into the outer surface of the mounting chuck, a multi-hole spool is installed at one end of the sleeve, a multi-hole interlayer is inserted into the inner side of the multi-hole spool, and a wire clamp is installed on one side of the multi-hole interlayer.
[0010] Optionally, the number of the porous interlayer and wire clamp is set to two, and the two porous interlayers and wire clamps respectively clamp the two sets of power lines. A misalignment protection box is inserted between the two porous interlayers. The surface of the misalignment protection box is in close contact with the inner wall of the porous interlayer. The data transmission line passes through the hole in the center of the mounting chuck and is inserted into the inner wall of the misalignment protection box.
[0011] Optionally, a pull plate is installed at the front end of the misalignment protection box, a miniature cylinder is installed on one side of the pull plate, and an elastic telescopic rod is provided on the other side of the pull plate. The other ends of the miniature cylinder and the elastic telescopic rod are installed on both sides of the multi-hole spool. A limit spring is installed at the tail of the multi-hole spool, and the other end of the limit spring is provided at the tail of the sleeve. The holes on both sides of the misalignment protection box are the same size and position as the holes on the surface of the multi-hole interlayer. The misalignment protection box slides in contact with the inner sides of the two multi-hole interlayers.
[0012] Optionally, the line end protection assembly includes a protective layer, which is installed at the rear of the housing of the video surveillance equipment. Three sealing cylinders are installed on the inner wall of the protective layer, and a square box is installed at the rear of the protective layer. A long strip box is inserted into the middle inner wall of the square box.
[0013] Optionally, the rear of the video surveillance equipment housing is detachably connected to a buckle. The protective layer is installed at the rear of the video surveillance equipment housing by the buckle. The power cord and data transmission line pass through the square box and the sealing cylinder and are connected to the wall. The data transmission line is separately inserted into the inside of the long box on the inner wall of the square box. One end of the long box is inserted into the rear of the video surveillance equipment housing. The end of the long box adjacent to the video surveillance equipment is aligned with the end of the misalignment protection box. The other end is sealed and connected to one end of the middle sealing cylinder among the three sealing cylinders.
[0014] This application also provides another technical solution: a video surveillance system, including a video surveillance camera, a back-end storage host, a power supply module and a backup power supply module; the power supply module supplies power to the camera module and miniature cylinder of the video surveillance camera through a power line, and the backup power supply module is electrically connected in parallel with the power line. When the mains power supply is normal, the backup power supply module maintains a standby energy storage state, and automatically switches to power supply to the whole machine when the mains power is interrupted or the main line is broken. The data transmission line of the video surveillance camera is led out separately through a long box and a middle sealed cylinder and connected to the back-end storage host. The camera module collects video images of the environmental monitoring area in real time and continuously transmits video monitoring data to the back-end storage host through the data transmission line. During the operation of the video surveillance camera, it relies on the natural airflow introduced by the side heat dissipation holes of the adjustable heat dissipation sealed component to complete passive heat dissipation. The honeycomb sound insulation board suppresses the noise of the equipment operation. The sealing cylinder, square box and long box of the line end protection component provide separate sealing protection for the two sets of power lines and data transmission lines. When the power cord shows signs of overheating or short circuit, the miniature cylinder pulls the pull plate, causing the misalignment protection box to slide and close inside the porous interlayer, isolating and protecting the data transmission line and preventing damage to the data transmission line due to power cord failure. The backup power module simultaneously ensures uninterrupted operation of the isolation action and video acquisition. The backend storage host continuously receives and stores the on-site water quality monitoring images, enabling 24 / 7 uninterrupted visual monitoring of the monitored scene.
[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, two sets of power cables are set on both sides of the data transmission line. The power cables are held by a multi-hole interlayer and wire clamps, and the lines are laid out in sections to avoid the local overheating caused by the tangling and accumulation of traditional cables. At the same time, by setting an adjustable heat dissipation and sealing component, external cold air is absorbed and enters the body through the side heat dissipation holes. Multiple sets of V-shaped air intake plates gather the airflow, and the arc-shaped air guide plate and air guide strip guide the cold air to evenly wrap around the camera module and the heat-generating circuit at the rear, which greatly improves the heat dissipation effect of the camera's rear wiring group. In addition, honeycomb sound insulation panels are laid on the inner wall of the body to absorb the noise generated by airflow and camera module operation.
[0016] If a short circuit or overheating fault occurs in the power line during operation, a miniature cylinder pulls the misalignment protection box to slide and seal it, isolating the data transmission line in an independent cavity. This isolates the high temperature and electrical sparks generated by the power line, protecting the data transmission line and ensuring timely transmission and storage of the final images. It prevents the data line from burning out and losing part of the environmental monitoring images due to overheating caused by line faults. The invention also features protective components, independent zoned wiring, and quick assembly / disassembly via snap-fit mechanisms. It uses three independent sealed cylinders with square and rectangular boxes, and separate channels for power and data lines. One end of the rectangular box is aligned with the misalignment protection box, and the other end is sealed to the middle sealed cylinder, forming independent zoned wiring. After sealing, the misalignment protection box is made of heat-resistant and fire-resistant material, effectively preventing open flames and preventing cascading losses caused by damage to a single line. Timely notification for emergency repairs can further reduce losses.
[0017] This invention uses a honeycomb soundproof panel to enclose the camera, preventing outdoor rain, fog, and dust from entering the camera's interior. Specifically designed for high-humidity outdoor monitoring areas, this effectively reduces camera image fogging and internal short circuits, lowering the frequency of field maintenance and replacements. A backup power module is also included; during normal mains power supply, the backup power supply stores energy in standby mode. In the event of a mains power outage or main line disconnection, the power supply circuit automatically switches to continuously power the camera module and miniature cylinder, ensuring normal operation of image acquisition and line fault isolation mechanisms. This reduces monitoring downtime caused by power outages and improves the stability of field environment monitoring. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.
[0021] like Figures 1 to 13As shown, an embodiment of the present invention provides a video surveillance camera, including a video surveillance device 1. A camera module 10 is housed inside the front end of the video surveillance device 1. Side heat dissipation holes 11 are provided on both sides of the video surveillance device 1. A mounting bracket 12 is provided at the bottom of the video surveillance device 1. A honeycomb sound insulation board 13 is installed on the inner wall of the video surveillance device 1. A power cord 14 and a data transmission line 15 are installed at the end of the camera module 10. An adjustable heat dissipation sealing component 2 is installed inside the rear end of the video surveillance device 1. The adjustable heat dissipation sealing component 2 is used to dissipate heat from the camera module 10 using natural wind. A wire end protection component 3 is inserted into the outer wall of the rear end of the video surveillance device 1. The wire end protection component 3 is used to protect the ends of the power cord 14 and the data transmission line 15. The power cord 14 is configured with two... The data transmission line 15 is positioned between the two sets of power lines 14. The adjustable heat dissipation and sealing assembly 2 includes an air duct 20, which is installed on the inner wall of the video monitoring equipment 1. An air collection plate 21 is installed on the side wall of the air duct 20. An air inlet 22 is opened at the bottom of the air collection plate 21. An air guide plate 23 is installed on the inner side of the air collection plate 21. An air guide strip 24 is installed on the outer wall of the air guide plate 23. Natural wind is introduced through the side heat dissipation hole 11 to complete the passive circulation heat dissipation in conjunction with the air duct 20, the air collection plate 21, and the air guide plate 23. The honeycomb sound insulation plate 13 absorbs the airflow noise of the equipment during operation. The two sets of power lines 14 and the middle data transmission line 15 are laid separately to avoid the cable tangling and heat accumulation from the source. The mounting bracket 12 can quickly complete the outdoor fixation of the whole machine, which is suitable for installation and use at open monitoring points such as rivers and lakes.
[0022] like Figures 7 to 13As shown, the air intake plate 21 is V-shaped, and the air guide plate 23 is arc-shaped and positioned close to the bottom of the air intake plate 21. Multiple sets of air intake plates 21 and air guide plates 23 are installed around the side wall of the air guide duct 20. The air guide duct 20 is sleeved on the outer surface of the camera module 10. A mounting chuck 26 is provided at the tail end of the camera module 10. A sleeve 27 is inserted into the outer surface of the mounting chuck 26. A perforated wire spool 28 is installed at one end of the sleeve 27. A perforated interlayer 29 is inserted into the inner side of the perforated wire spool 28. A wire clamp 290 is installed on one side of the multi-hole interlayer 29. Two multi-hole interlayers 29 and two wire clamps 290 are provided. The two multi-hole interlayers 29 and two wire clamps 290 respectively clamp two sets of power cables 14. A misalignment protection box 291 is inserted between the two multi-hole interlayers 29. The surface of the misalignment protection box 291 is in close contact with the inner wall of the multi-hole interlayer 29. The data transmission cable 15 passes through the hole in the center of the mounting chuck 26 and is inserted into the inner wall of the misalignment protection box 291. A pull plate 292 is installed at the front end of the misalignment protection box 291. A miniature cylinder 293 is installed on one side of the pull plate 292, and an elastic telescopic rod 294 is provided on the other side of the pull plate 292. The other ends of the miniature cylinder 293 and the elastic telescopic rod 294 are installed on both sides of the porous spool 28. A limit spring 295 is installed at the tail of the porous spool 28, and the other end of the limit spring 295 is located at the tail of the sleeve 27. The holes on both sides of the misalignment protection box 291 are the same size and position as the holes on the surface of the porous interlayer 29. The misalignment protection box 291 slides and fits against the inner side of the two porous interlayers 29. The V-shaped air intake plates 21 arranged in a ring can gather external cold air, and the arc-shaped air guide plate 23, together with the air guide strip 24, allows the airflow to evenly wrap around the camera module 10, improving the heat dissipation uniformity. The porous interlayer 29, together with the wire clamp 290, individually clamps the two sets of power cables 14 to achieve zoned wiring. The miniature cylinder 293 can pull the misalignment protection box 291 to slide misalignment seal, isolate the high temperature electric sparks generated by the short-circuited power cable, and the limit spring 295 buffers outdoor vibration, prevents the sleeve 27 and the porous wire spool 28 from loosening, and stabilizes the internal circuit clamping structure.
[0023] like Figure 5 , Figure 8 and Figure 13As shown, the line end protection component 3 includes a protective layer 30, which is installed at the rear of the housing of the video surveillance equipment 1. Three sealing cylinders 31 are installed on the inner wall of the protective layer 30. A square box 32 is installed at the rear of the protective layer 30, and a long strip box 33 is inserted into the middle inner wall of the square box 32. A snap fastener 34 is detachably inserted into the rear of the housing of the video surveillance equipment 1. The protective layer 30 is secured to the rear of the housing of the video surveillance equipment 1 via the snap fastener 34. The power cord 14 and the data transmission cord 15 both pass through the square box 32 and the sealing cylinders 31 and are connected to the wall. The data transmission cord 15 is separately inserted into the interior of the long strip box 33 on the inner wall of the square box 32. One end of the long strip box 33 is inserted into the rear of the housing of the video surveillance equipment 1, and the end of the long strip box 33 adjacent to the video surveillance equipment 1 is aligned with the end of the misalignment protection box 291. One end is sealed and connected to the middle sealing cylinder 31 among the three sealing cylinders 31. The snap buckle 34 enables quick installation and removal of the protective layer 30, facilitating field line maintenance. The three independent sealing cylinders 31, together with the square box 32 and the long box 33, isolate the power line 14 and the data transmission line 15 through separate channels. The long box 33 and the misalignment protection box 291 are precisely connected to form a complete sealed pipeline, preventing outdoor rainwater, fog, and dust from entering the equipment through the gaps in the cable outlet. This effectively reduces the probability of line corrosion and circuit board short circuit failure in high humidity outdoor environments. The protective layer 30 is made of glass fiber reinforced halogen-free flame-retardant PPS integral injection molding, with a composite flame-retardant silicone rubber sealing gasket layer on the inner wall. It can resist the penetration of high humidity fog and rainwater in the water quality monitoring area, while isolating the high temperature and electric sparks generated by the short circuit of the power line 14, taking into account the triple performance of fireproof, moisture-proof, and corrosion-resistant.
[0024] This application also provides another technical solution: a video surveillance system, including a video surveillance camera, a back-end storage host, a power supply module and a backup power supply module; the power supply module supplies power to the camera module 10 and the miniature cylinder 293 of the video surveillance camera through a power line 14, and the backup power supply module is electrically connected in parallel with the power line 14. When the mains power supply is normal, the backup power supply module maintains a standby energy storage state, and automatically switches to power supply for the whole machine when the mains power is interrupted or the main line is broken. The data transmission line 15 of the video surveillance camera is led out separately through the long box 33 and the middle sealing cylinder 31 and connected to the back-end storage host. The camera module 10 collects video images of the environmental monitoring area in real time and continuously transmits video monitoring data to the back-end storage host through the data transmission line 15. During the operation of the video surveillance camera, it relies on the natural wind introduced by the side heat dissipation hole 11 of the adjustable heat dissipation sealing component 2 to complete passive heat dissipation. The honeycomb sound insulation board 13 suppresses the noise of the equipment operation. The sealing cylinder 31, square box 32 and long box 33 of the line end protection component 3 provide separate sealing protection for the two sets of power lines 14 and data transmission lines 15. When the power line 14 shows an overheating or short-circuit fault signal, the miniature cylinder 293 pulls the pull plate 292, causing the misalignment protection box 291 to slide and misalign inside the porous interlayer 29 to isolate and protect the data transmission line 15, preventing the power line fault from damaging the data transmission line 15. The backup power module simultaneously ensures uninterrupted operation of the isolation action and video acquisition. The back-end storage host continuously receives and stores the on-site water quality monitoring images, realizing all-weather uninterrupted visual monitoring of the monitored scene.
[0025] The working principle of the technical solution provided by this invention is as follows: First, during the assembly and wiring work, the camera module 10 is installed inside the video surveillance equipment 1. The two sets of power cables 14 are placed on the left and right sides of the data transmission line 15. The mounting chuck 26 at the tail of the camera module 10 is fitted with a sleeve 27. The sleeve 27 is connected to a multi-hole cable tube 28. The two sets of multi-hole interlayers 29 inside the tube are paired with cable clamps 290 to clamp the two power cables 14 respectively, thereby separating and fixing the power supply lines and avoiding multiple cables from tangling and piling up from the source.
[0026] Subsequently, a misalignment protection box 291 is placed between the two porous sandwich panels 29, allowing the data transmission line 15 to pass through the center hole of the mounting chuck 26 and enter the misalignment protection box 291 separately, completely separating the power line from the data line; the front end of the misalignment protection box 291 is connected to a pull plate 292, one side of which is equipped with a miniature cylinder 293 and the other side with an elastic telescopic rod 294. The other ends of the cylinder and the telescopic rod are fixed to both sides of the porous cable drum 28. At the same time, the limiting spring 295 at the tail of the porous cable drum abuts against the tail of the sleeve 27, which can buffer outdoor vibration and prevent the internal circuit components from loosening and shifting.
[0027] Meanwhile, the rear of the video surveillance equipment 1 is protected by a connector terminal protection component 3 secured by a snap-fit 34. Inside the protective layer 30, there are three independent sealed cylinders 31. A square box 32 is installed at the rear, with a long strip box 33 inserted in the middle of the square box. Two sets of power cables 14 pass through the left and right channels of the square box and are connected to the left and right sealed cylinders 31. The data transmission cable 15 runs separately along the long strip box 33 and is connected to the middle sealed cylinder 31. The end of the long strip box close to the body is precisely aligned with the end of the misalignment protection box 291. The entire line forms a sealed channel, effectively preventing outdoor rainwater, fog, and dust from entering the equipment from the cable gaps, thus achieving moisture and dust protection.
[0028] During normal operation of the camera, the camera module 10 continuously collects outdoor water quality monitoring images, and the data transmission line 15 independently transmits video signals to the back-end storage host. The power supply module continuously supplies power to the camera module 10 and the miniature cylinder 293 via the power line 14. The backup power supply module is electrically connected in parallel with the power line. When the mains power is normal, the backup power supply is only in standby energy storage state. Once the mains power fails or the main line is broken, the backup power supply will instantly switch the power supply circuit to ensure the continuous operation of the whole machine.
[0029] In addition, the adjustable heat dissipation sealing component 2 will be activated synchronously throughout the operation of the equipment to dissipate heat. External natural airflow flows into the body from the side heat dissipation holes 11 on both sides of the video surveillance equipment 1. The side wall of the air duct 20 arranged around the camera module 10 is equipped with multiple sets of V-shaped air collection plates 21. After the air collection plates gather the airflow, it is sent into the duct through the bottom air inlet 22. The arc-shaped air guide plate 23, together with the air guide strip 24, adjusts the airflow direction so that the cool air evenly wraps the camera module 10 and fully removes the heat generated by the camera module and the power cord 14. At the same time, the honeycomb sound insulation plate 13 laid on the inner wall of the body will absorb the noise generated by the airflow and the operation of the camera module, reducing the noise diffusion to the outside.
[0030] Once the system detects an overheating or short-circuit fault signal in the power cord 14, it immediately triggers the micro cylinder 293 to operate. The cylinder pulls the pull plate 292, causing the misalignment protection box 291 to slide forward. The elastic telescopic rod 294 extends and retracts synchronously to ensure a smooth sliding process. After the misalignment protection box 291 moves forward, the holes on both sides and the holes in the porous interlayer 29 are misaligned and sealed, completely enclosing the data transmission line 15 in an independent cavity. This isolates the high temperature and electrical sparks generated by the faulty power cord, preventing the data cord from being burned out. Moreover, the airflow in the duct 20 can concentrate on dissipating heat from the faulty power cord area, slowing down the aging of the line.
[0031] Finally, the entire monitoring system operates in a coordinated manner. The camera module continuously captures images of the water environment, while the back-end storage host continuously receives and stores the monitoring videos. The branch line isolation, multiple sealing protections, and natural air cooling structure play their roles simultaneously. Even in the event of power outages, short circuits, or other emergencies, the backup power supply and misalignment protection mechanism can maintain video acquisition and line protection functions, enabling uninterrupted 24 / 7 visual monitoring of the outdoor water environment.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
