Description

Technical Field

[0001] This invention relates to the field of surveillance camera technology, specifically to an intelligent security surveillance camera. Background Technology

[0002] Security surveillance cameras are electronic devices used for security and video monitoring. By collecting images or video signals, they enable real-time monitoring, recording, early warning, and management of specific areas. They are widely used in public safety, commercial venues, homes, and industrial environments.

[0003] As disclosed in the prior art, Chinese patent application number CN202211306479.2 discloses a security monitoring camera, including a base, a connecting column, and a top plate, and further including: a camera body, which is mounted on the base; a protective cover, which is mounted on the base and located outside the camera body, the base having an annular groove, the bottom of the protective cover having a connecting ring, the connecting ring being installed in the annular groove, the protective cover being rotatably connected to the base through the connecting ring; a drive rod being provided on the top of the protective cover; a cleaning plate, the cleaning plate being connected to a movable rod, the movable rod being slidably mounted on the connecting column, the cleaning plate having a sponge on the side facing the protective cover; and a drive mechanism being provided on the top plate for driving the drive rod to rotate and driving the movable rod to slide.

[0004] For example, in the prior art, Chinese patent application number CN201710998913.0 discloses a security surveillance camera, including a fixed bracket, a connecting rod, a housing, and an infrared detector. The fixed bracket is installed on the wall, and the connecting rod is provided on the surface of the fixed bracket. A rotating seat is installed at the end of the connecting rod, and the housing is connected above the rotating seat. The housing is a cylindrical hollow structure, and a dust cover is provided on the top of the housing. A dustproof lens is installed on the inner end face of the housing, and an infrared detector is provided on the surface of the dustproof lens. A lens group is installed inside the dustproof lens, and a focusing motor is connected to the lens group. A filter is installed on the diagonal motor, and an image sensor is provided on the filter. The image sensor is connected to a circuit board through wires, and the circuit board is fixedly installed inside the housing.

[0005] For example, in the prior art, Chinese patent application number CN201711396184.8 discloses a security camera with good heat dissipation, including a fixing plate and a protective shell. A support frame is installed on the front upright plate of the fixing plate by bolts. A motor base is provided at the front end of the support frame. A motor base is provided above the motor base. A fixing seat is fixed above the motor base by a pin. A rotary motor is provided on the side of the rotating seat. The protective shell is provided above the fixing seat. A control panel is provided on the side of the protective shell. A human signal sensor is provided at the lower end of the front surface of the protective shell. A monitoring lens is provided above the human signal sensor. An image processor is provided behind the monitoring lens. A battery is provided inside the rear of the protective shell. A cooling fan is provided at the top inside the protective shell.

[0006] Based on the above information, it can be seen that existing surveillance cameras generate a certain amount of heat during operation, so they generally need to be equipped with heat dissipation structures to achieve the purpose of timely heat dissipation. However, in actual use, security surveillance cameras are generally installed outdoors. On rainy days, the air humidity is high, and heat dissipation will bring humid air into the casing, which can easily cause damage to internal components. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent security monitoring camera to solve the problem of damage caused by the entry of humid air mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an intelligent security monitoring camera, comprising a camera housing with a square structure, a protective cover fixedly installed on the top of the camera housing, the camera housing being mounted on a mounting bracket using a support frame, a camera body fixedly installed inside the camera housing, an air inlet slot on the top of the camera housing, and an air outlet slot on the rear side of the camera housing, and a cooling fan corresponding to the air outlet slot installed inside the camera housing, the cooling fan driving airflow, allowing external air to enter the camera housing through the air inlet slot and then exit through the air outlet slot, thereby dissipating heat through airflow. A protective lens is provided at the front end of the housing, and a partition plate is fixedly installed inside the camera housing, dividing the interior of the camera housing into left and right spaces. The drying cotton passes through the partition plate. A ring-shaped drying cotton is provided at the upper end of the camera housing. The drying cotton absorbs moisture from the air, reducing the risk of moisture entering the interior and damaging the components. A drive roller is rotatably installed inside the camera housing to rotate the drying cotton. A drying mechanism is provided inside the camera housing. The drying mechanism uses the heat inside the camera housing to dry the drying cotton. A motor drives the drive roller to rotate, thereby using the friction of the drive roller to rotate the drying cotton, rotating the dried cotton to the air inlet slot.

[0009] Preferably, the protective lens comprises a first lens and a second lens, and the cavity between the first lens and the second lens is a heating cavity. The upper surface of the camera housing is provided with an exhaust hole communicating with the heating cavity, and a horizontally arranged conveying pipe is fixedly installed at the lower end of the camera housing. The front end of the conveying pipe is connected to the heating cavity, and a conveying pump is fixedly installed at the rear end of the conveying pipe. The conveying pump delivers hot air from inside the camera housing to the heating cavity through the conveying pipe. The hot air is delivered to the heating cavity through the conveying pipe to achieve the purpose of heating the protective lens, maintaining the temperature of the protective lens, and avoiding water vapor on the protective lens due to large temperature differences, which would affect the image clarity.

[0010] Preferably, the drying mechanism includes a through hole in the middle of the partition plate and a squeezing roller located inside the drying cotton. The squeezing roller is installed below the mounting block. When the gas flows and carries away the heat, it passes through the through hole and reaches the right side of the drying cotton, where hot air dries the right side of the drying cotton.

[0011] Preferably, the extrusion roller has drying holes evenly spaced on its side, and the lower end of the mounting block extends into the extrusion roller. A sealing ring that fits against the outer surface of the mounting block is fixedly installed on the inner side of the extrusion roller. A return spring is fixedly installed between the mounting block and the inner wall of the extrusion roller. When air injection stops, the extrusion roller is driven to return to its original position under the action of the return spring. Heat-conducting fins with equal spacing are fixedly installed on the lower inner surface of the extrusion roller. There are two extrusion rollers symmetrically arranged on the left and right sides. A connecting pipe for injecting air into the extrusion roller is fixedly installed on the upper surface of the extrusion roller. The lower end of the connecting pipe is connected to a heat exchange pipe through a second control valve. The heat exchange pipe is located on the left side of the partition plate. The hot air on the left side of the partition plate is transported to the connecting pipe through the heat exchange pipe by a delivery pump. Then, it is transported to the inside of the extrusion roller through the connecting pipe and then discharged from the drying holes on the side of the extrusion roller. The hot air discharged from the drying holes, together with the hot air passing through the through holes, achieves the purpose of drying the cotton on both sides.

[0012] Preferably, the heat exchange tube has an overall bent structure, and the lower end of the heat exchange tube is connected to the delivery pipe through a first control valve.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This intelligent security monitoring camera adopts a novel structural design, the specific details of which are as follows: 1. The cooling fan drives the airflow, allowing external air to enter the camera housing through the air inlet and then exit through the air outlet. The airflow carries away heat to achieve the purpose of heat dissipation. A drying cotton is installed at the air inlet. When the air enters the camera housing, it passes through the drying cotton, which absorbs the moisture in the air and reduces the amount of moisture entering the interior and causing damage to the components. Furthermore, the camera housing is divided into two spaces, left and right, by a partition plate. When the gas flows and carries away the heat, it passes through the through hole to the right side of the drying cotton. The right side of the drying cotton is dried by hot air. The motor drives the drive roller to rotate, and the friction of the drive roller drives the drying cotton to rotate. The dried cotton is then rotated to the air inlet slot, which improves the long-term performance of the drying cotton.

[0014] 2. The hot air on the left side of the partition plate is transported to the connecting pipe through the heat exchange pipe using the conveying pump. Then it is transported to the inside of the extrusion roller through the connecting pipe and discharged from the drying hole on the side of the extrusion roller. The hot air discharged from the drying hole, together with the hot air passing through the through hole, achieves the purpose of drying the cotton on both sides, thereby improving the overall drying effect. Furthermore, the exhaust speed of the drying hole is less than the air injection speed of the connecting pipe. When the connecting pipe injects air into the squeezing roller, the air pressure inside the squeezing roller increases. The air pressure pushes the squeezing roller to move downward relative to the mounting block. When the air injection stops, the squeezing roller is driven to return to its original position under the action of the return spring. Thus, the squeezing roller intermittently squeezes the drying cotton (the two squeezing rollers on the left and right alternately rise and fall), thereby making the drying cotton move up and down to achieve a better drying effect.

[0015] 3. The first control valve controls the flow direction of the hot air delivered by the delivery pump. When the temperature difference between day and night is large, the hot air is delivered to the heating chamber through the delivery pipe to heat the protective lens, maintain the temperature of the protective lens, and avoid water fog on the protective lens due to large temperature differences, which would affect the clarity of the shot.

[0018] 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.

[0019] Example 1: Please refer to Figures 1-4 In order to achieve the purpose of drying the heat dissipation air, this embodiment provides the following technical solution, which specifically discloses: a camera housing 1 with a square structure, a protective cover 2 fixedly installed on the top of the camera housing 1, the camera housing 1 being mounted on the mounting bracket 4 using a support frame 3, a camera body 8 fixedly installed inside the camera housing 1, an air inlet slot 5 opened on the top of the camera housing 1, and an air outlet slot 6 opened on the rear side of the camera housing 1, and a cooling fan 7 corresponding to the air outlet slot 6 installed inside the camera housing 1, a protective lens 9 provided at the front end of the camera housing 1, a drying cotton 11 with a ring structure provided at the top of the camera housing 1, and a drive roller 12 rotatably installed inside the camera housing 1 to drive the drying cotton 11 to rotate.

[0020] When using the device, first use bolts and mounting bracket 4 to install the entire device in a designated outdoor location (such as a wall) and connect the circuit. Use the camera body 8 inside the camera housing 1 to perform shooting and monitoring operations. During the use of the device, turn on the cooling fan 7 inside the camera housing 1. The cooling fan 7 drives the airflow. At this time, the outside air enters the camera housing 1 through the air inlet slot 5 and then exits from the air outlet slot 6. In this process, the airflow carries away heat to achieve the purpose of heat dissipation. Before the air enters the camera housing 1, it first comes into contact with the drying cotton 11. The drying cotton 11 absorbs the moisture in the air to achieve the purpose of dehumidification and reduce the possibility of moisture entering and causing damage.

[0021] Example 2: Please refer to Figures 5-11 To achieve the goal of drying the cotton 11 and ensuring its long-term use, this embodiment provides the following technical solution: A partition plate 10 is fixedly installed inside the camera housing 1, and the cotton 11 passes through the partition plate 10. A drying mechanism is provided inside the camera housing 1. The drying mechanism uses the heat inside the camera housing 1 to dry the cotton 11. The drying mechanism includes a through hole 13 in the middle of the partition plate 10 and a squeeze roller 18 located inside the cotton 11. The squeeze roller 18 is installed below the mounting block 19. Drying holes 20 are evenly spaced on the side of the squeeze roller 18, and the lower end of the mounting block 19 extends into the squeeze roller 18. Furthermore, a sealing ring 21 that fits against the outer surface of the mounting block 19 is fixedly installed on the inner side of the extrusion roller 18. A return spring 22 is fixedly installed between the mounting block 19 and the inner wall of the extrusion roller 18. Heat-conducting fins 23 with equal spacing are fixedly installed on the lower inner surface of the extrusion roller 18. Two extrusion rollers are symmetrically arranged on the left and right sides. A connecting pipe 24 for injecting air into the extrusion roller 18 is fixedly installed on the upper surface of the extrusion roller 18. The lower end of the connecting pipe 24 is connected to the heat exchange pipe 26 through the second control valve 25. The heat exchange pipe 26 is located on the left side of the partition plate 10. The heat exchange pipe 26 has a bent structure. The lower end of the heat exchange pipe 26 is connected to the conveying pipe 14 through the first control valve 16.

[0022] During rainy weather, when the external air humidity is high, the motor inside the camera housing 1 periodically drives the drive roller 12 to rotate. The friction between the drive roller 12 and the drying cotton 11 causes the drying cotton 11 to rotate, moving the cotton 11 from its position corresponding to the air inlet slot 5 into the camera housing 1 (located at the right end of the partition plate 10). The unused portion of the drying cotton 11 then rotates to its corresponding position in the air inlet slot 5, ensuring its effectiveness. At this time, the airflow carrying heat from inside the camera housing 1 passes through the through hole 13 in the middle of the partition plate 10 to the drying cotton 11 (the portion of the drying cotton 11 that corresponds to the air inlet slot 5, i.e., already absorbed moisture). The heat dries the drying cotton 11. Simultaneously, the delivery pump 15 is activated, using it to deliver the hot air from the left side of the partition plate 10 to the heat exchange tube 26 (at this time, the first control valve 16 controls the opening of the heat exchange tube 26). The hot air then passes through the heat exchange... The air is conveyed through pipe 26 to connecting pipe 24 and finally injected into the squeeze roller 18 and discharged through the drying hole 20 on the side of the squeeze roller 18, achieving the purpose of drying both the upper and lower sides of the cotton 11 simultaneously. Since the speed of air injection through connecting pipe 24 is greater than the speed of air discharge through drying hole 20, the air pressure inside the squeeze roller 18 increases. Under other actions, the squeeze roller 18 is pushed downward, and the squeeze roller 18 squeezes the cotton 11 downward. Since two squeeze rollers 18 are symmetrically arranged on the left and right, and work alternately under the control of the second control valve 25 (i.e., air is injected into the two squeeze rollers 18 alternately, and the other squeeze roller 18 stops injecting air when one squeeze roller 18 is injected), the air pressure inside the squeeze roller 18 that stops injecting air continuously decreases. Under the elastic action of the return spring 22, the squeeze roller 18 is pulled upward to return to its original position, so that the two squeeze rollers 18 move up and down alternately, causing the cotton 11 to tilt left and right, thus improving the drying effect.

[0023] Example 3: Please refer to Figure 7 and Figure 12 In order to reduce water mist, this embodiment provides the following technical solution, which specifically discloses that: the protective lens 9 includes two parts, a first lens 901 and a second lens 902, and the cavity between the first lens 901 and the second lens 902 is a heating cavity 903. The upper surface of the camera housing 1 is provided with an exhaust hole 17 that communicates with the heating cavity 903. A horizontally arranged conveying pipe 14 is fixedly installed at the lower end of the camera housing 1. The front end of the conveying pipe 14 communicates with the heating cavity 903, and a conveying pump 15 is fixedly installed at the rear end of the conveying pipe 14. The conveying pump 15 conveys the hot air inside the camera housing 1 to the heating cavity 903 through the conveying pipe 14.

[0024] When the temperature difference between day and night is large, the first control valve 16 closes the heat exchange tube 26 channel and opens the delivery tube 14 channel. At this time, the hot air delivered by the delivery pump 15 is delivered through the delivery tube 14 to the heating chamber 903 between the first lens 901 and the second lens 902, and finally discharged from the exhaust hole 17 to achieve the purpose of heating the protective lens 9, keeping the protective lens 9 at a constant temperature, and avoiding water mist on the surface of the protective lens 9 due to temperature difference, which would affect the shooting effect.
