Description

Technical Field

[0001] The present invention relates to the technical field of surveillance cameras, and in particular to an anti-fog and waterproof all-weather intelligent surveillance camera. Background Art

[0002] With the wide application of security surveillance technology, outdoor intelligent surveillance cameras play an important role in urban management, traffic monitoring, environmental monitoring and other fields. However, the complex and changeable outdoor climate environment (such as high temperature and high humidity, rainfall and snowfall, day-night temperature difference, etc.) poses strict requirements on the anti-fog and waterproof performance of surveillance cameras.

[0003] Currently, traditional surveillance cameras mostly adopt a sealed structure and a hydrophobic coating to achieve the waterproof function. By setting rubber sealing rings at the joints of the housing and performing hydrophobic coating treatment on the lens or the cover, rainwater intrusion can be blocked to a certain extent. However, during long-term use, the sealing rings are prone to aging and deformation under the influence of ultraviolet rays and temperature changes, resulting in sealing failure; under the erosion of dust and oil stains, the hydrophobic performance of the hydrophobic coating will rapidly decay, causing rainwater to remain on the lens surface and form water marks, seriously affecting the imaging clarity.

[0004] In terms of anti-fog, in the prior art, such as a surveillance camera and its waterproof and anti-fog method with the patent authorization publication number CN115529402B, when fog appears on the surface of the glass cover, the method of using an electric heating sheet to raise the temperature to remove the fog is adopted. Although it can inhibit the condensation of water mist, from a thermodynamic perspective, this passive heating method has obvious defects. On the one hand, its heat conduction efficiency is low, and the power of the electric heating sheet needs to be increased to a relatively high level, resulting in high energy consumption; on the other hand, there is a time delay in the heat transfer from the electric heating sheet to the surface of the glass cover, and the response speed is slow. When the temperature difference changes violently, it is difficult to quickly remove the fog. More importantly, this heating method only acts on the surface of the glass cover and has no effect on the condensed water inside the device, such as the circuit board and the lens assembly. Long-term humidity is likely to cause circuit corrosion, and it is difficult to meet the requirements of all-weather stable monitoring. Summary of the Invention

[0005] In order to overcome the disadvantages mentioned in the background art, the present invention provides an anti-fog and waterproof all-weather intelligent surveillance camera.

[0006] The technical solution is as follows: An anti-fog and waterproof all-weather intelligent monitoring camera, which includes an adjustment bracket, a housing, a mounting frame, a protective lens, a rain shield, a top frame, a core module and a controller. The adjustment bracket is fixedly installed with the housing. The mounting frame is installed on the left side of the housing. The core module is integrated inside the mounting frame.

Through holes are spacedly opened on the circuit board, and the through holes communicate with the inside of the cylinder body. Notch openings are opened on the upper and lower sides of the circuit board, which communicate with the ventilation cavity.

[0008] As a further preferred solution, an anti-fog coating is provided on the surface of the protective lens and the surface of the lens in the core module.

[0009] As a further preferred solution, it also includes a rotating shaft, a rotating block, a rotating disk, a storage frame, a return spring and a wind guide wheel. The rotating block is rotatably connected to the right side of the cylinder body. The rotating shaft is spline-connected to the rotating block. The rotating disk is connected to the right side of the rotating shaft. The storage frame storing desiccant is rotatably connected to the outside of the rotating disk. The storage frame is rotatably connected to the rotating shaft. A plurality of scraping strips are circumferentially spacedly connected to the outside of the rotating disk, and these scraping strips are in close contact with the inner wall of the storage frame. A plurality of uniformly distributed through holes are opened on the outer side wall of the storage frame. The right end of the rotating shaft is connected with the wind guide wheel. The wind guide wheel is rotatably connected to the right side wall of the storage frame. A return spring is connected between the left side of the rotating disk and the rotating block, and the return spring is sleeved on the rotating shaft. In the initial state, the storage frame and the wind guide wheel are in close contact with the right port of the cylinder body to form a sealed state.

[0010] As a further preferred solution, it further includes a guide rod, a sealing ring, gears, fixed racks and rack rods. The upper and lower sides of the storage frame are respectively connected with rack rods. The two rack rods are slidably connected to the upper and lower sides inside the housing. Gears are respectively rotatably connected to the positions near the two rack rods inside the housing through mounting seats. The gears are engaged with the corresponding rack rods. A plurality of guide rods are slidably connected to the position of the housing in the ventilation cavity along the circumferential direction. A sealing ring is connected between the right ends of these guide rods. In the initial state, the sealing ring seals the channel through which the ventilation cavity flows through the exhaust groove. Fixed racks are respectively connected to the uppermost and lowermost guide rods. The fixed racks are engaged with the corresponding gears.

[0011] As a further preferred solution, it further includes a water collecting frame, a solenoid valve and a nozzle. The middle part of the top frame is designed as a concave structure. A water collecting hole is opened on the left side of the concave structure. A filter screen is installed at the water collecting hole. The left side of the bottom of the top frame is connected with a water collecting frame. The water collecting frame communicates with the water collecting hole. A solenoid valve is installed on the left side of the water collecting frame. A nozzle is installed at the bottom of the solenoid valve. The nozzle penetrates through the mounting frame, and its spraying direction faces the protective lens. Both the solenoid valve and the nozzle are electrically connected to the controller through wires.

[0012] As a further preferred solution, it further includes a motor, a first scraper and a second scraper. A motor is installed on the lower right side of the protective lens. The motor is located inside the mounting frame. The output shaft of the motor penetrates through the left side of the protective lens and is connected with the first scraper. A second scraper is slidably connected to the first scraper. The first scraper and the second scraper are closely attached to the wall surface of the protective lens. A guide groove is opened at the position on the lower left side of the protective lens outside the first scraper. A protrusion is arranged on the second scraper. The protrusion is in sliding fit with the guide groove. The motor is electrically connected to the controller.

[0013] As a further preferred solution, it further includes a sealing strip. The connection between the housing and the mounting frame and the connection between the rain shield and the housing are both sealed with sealing strips.

[0014] The present invention has the following advantages: 1. This solution adopts an active thermal convection defogging system, which has the following breakthrough improvements compared with the traditional passive heating method: The filtered air is sent into the cylinder by a fan for heating. After being quickly heated by the heating wire, the hot air forms a directional air flow through the through holes of the circuit board, and the fog inside the protective lens and the mounting frame can be quickly evaporated and removed in a short time; The thermal convection covers all areas inside the mounting frame, synchronously eliminating the condensed water on components such as the lens and the circuit board, preventing the electronic components from getting damp, effectively avoiding the water mist condensation caused by the temperature difference, and ensuring clear imaging of the camera in bad weather.

[0015] 2. Components such as the sealing ring, air guide wheel, and storage box work together. During the defogging operation, the circulation channel of the hot air can be automatically opened, and the desiccant is stirred by the rotating disk and the scraping strip, effectively contacting with moisture for dehumidification. When the defogging ends, the circulation channel can be automatically closed, effectively preventing external moisture or rain from entering, ensuring the stability of the internal environment, reducing manual intervention, and improving the convenience and reliability of equipment use.

[0016] 3. An integrated rainwater collection and automatic cleaning system is adopted. The sunken structure of the top frame, together with the water collection holes and filters, realizes rainwater collection. When the protective lens is contaminated with dust and water marks, the solenoid valve and nozzle can be started remotely, and the collected rainwater is used for spraying and cleaning. Subsequently, the motor drives the first scraper and the second scraper to automatically complete wiping, expanding the contact area to improve the cleaning effect, effectively reducing the manual maintenance cost, and keeping the monitoring vision clear.

[0017] 4. A multiple waterproof design is adopted. The rain shield has a streamlined structure that is wider at the top and narrower at the bottom, guiding rainwater to slide down quickly using the principle of fluid mechanics. Combined with the design of the water leakage groove, accumulated water is effectively discharged. Sealing strips are equipped at the joints between the outer shell and various components for sealing, which can prevent rainwater and water vapor from invading the interior of the equipment, providing reliable waterproof protection for the core module, and ensuring the normal operation of the equipment in extreme weather such as heavy rain and heavy snow.

Detailed implementation manners

[0034] Example 1: An anti-fog and waterproof all-weather intelligent monitoring camera, as Figures 1-6As shown, it includes an adjustment bracket 1, a housing 101, a mounting frame 102, a protective lens 103, a rain shield 104, a top frame 105, a core module 106, a controller 107, a cylinder 201, a heating wire 202, a fan 203, and a filter screen 204. The adjustment bracket 1 serves as the installation base, on which the housing 101 is fixedly installed. The mounting frame 102 is installed on the left side of the housing 101 by bolts. The core module 106 is integrated inside the mounting frame 102, and the controller 107 is installed on the core module 106 by bolts. A protective lens 103 is installed on the left side wall of the mounting frame 102 to protect the core module 106 from external physical damage and dust intrusion. The controller 107 is electrically connected to the remote control system. The adjustment bracket 1 is equipped with a steering module, which supports remotely adjusting the overall orientation of the housing 101 through the remote control system to meet the requirements of different monitoring perspectives. The rain shield 104 with a streamlined structure that is wider at the top and narrower at the bottom is installed on the right side of the housing 101 by bolts, and a water leakage groove 1041 is opened at its narrow end. This structural design can effectively prevent external rainwater from entering the interior of the housing 101. Even when water accumulates in the rain shield 104 due to the change in the camera angle, the accumulated water can quickly drain through the water leakage groove 1041. The top frame 105 is connected to the top of the housing 101. A cylinder 201 is connected to the middle part inside the housing 101. A ventilation cavity 205 is formed between the outside of the cylinder 201 and the inner wall of the housing 101. Exhaust slots 206 are opened on the right side, front side, and rear side of the top of the housing 101 to provide a discharge channel for the air in the ventilation cavity 205. The heating wire 202 is wound inside the cylinder 201. The fan 203 is installed on the left side inside the rain shield 104 by bolts, and the filter screen 204 is detachably installed at the position on the right side of the fan 203 inside the rain shield 104. The core module 106, the fan 203, and the heating wire 202 are all electrically connected to the controller 107 through circuits to realize the intelligent control of each component by the controller 107. The monitoring camera also includes a sealing strip 7. The connection between the housing 101 and the mounting frame 102 and the connection between the rain shield 104 and the housing 101 are both sealed with the sealing strip 7. The sealing strip 7 is made of a waterproof and aging-resistant rubber material, has good elasticity and sealing performance, and can effectively prevent external rainwater and water vapor from entering the interior of the housing 101 and the mounting frame 102 through the connection gaps, ensuring the use stability of the internal electronic components.

[0035] As Figure 2As shown, the core module 106 includes a circuit board, a lens, an imaging sensor, a chip processor, and two lamp bodies. The circuit board is installed in the mounting frame 102 by screws. The circuit board serves as the core carrier, and the lens, imaging sensor, chip processor, lamp bodies, and controller 107 are all installed on the circuit board. The lens is firmly connected to the circuit board through a lens mount, and its function is to focus external light onto the imaging sensor. The imaging sensor, as a key component for image information conversion, converts the optical image information collected by the lens into an electrical signal and transmits it to the controller 107. The chip processor is responsible for subsequent processing tasks such as analog-to-digital conversion, image signal processing, and encoding compression of the electrical signal. The two lamp bodies are symmetrically distributed on both sides of the lens, connected to the circuit board by wires, powered by the circuit board, and can automatically adjust the brightness and working mode according to the ambient light conditions under the control of the controller 107. For example, the infrared lamp or white lamp is automatically turned on in a dim environment to enhance the auxiliary lighting effect. In addition, through holes are spacedly opened on the circuit board, and the through holes are communicated with the inside of the cylinder body 201, providing a channel for the hot air inside the cylinder body 201 to enter the mounting frame 102. Notches are opened on the upper and lower sides of the circuit board, which are communicated with the ventilation cavity 205, facilitating the excess air in the mounting frame 102 to flow into the ventilation cavity 205 to form an air circulation path. Anti-fog coatings are provided on the surface of the protective lens 103 and the surface of the lens in the core module 106. It can form a smooth protective film on the surfaces of the protective lens 103 and the lens, making it difficult for water vapor to adhere, thus achieving the anti-fog effect.

[0036] In the device deployment stage, based on the multi-degree-of-freedom adjustment mechanism of the adjustment bracket 1, precise calibration of the pitch angle and horizontal angle can be achieved. In cooperation with the steering module, the orientation of the housing 101 can be accurately set through the remote control system, and the surveillance camera can be installed at the designated outdoor surveillance location. After the device is put into use, the components in the core module 106 work together. The lens collects external optical image information, which is converted into an electrical signal by the imaging sensor, and then processed by the chip processor. The processed data is transmitted to the remote control system through the controller 107 to achieve the functions of remote monitoring and management. When the camera detects abnormal situations such as motion detection and sound trigger, it will immediately send an alarm signal to the remote control system so that users can obtain information and handle it in a timely manner.

[0037] In the rainy season or winter, due to temperature differences, water mist is likely to form on the surface of the protective lens 103 inside the mounting frame 102, affecting the imaging clarity. At this time, the user sends an instruction to the controller 107 through the remote control system. After receiving the instruction, the controller 107 starts the heating wire 202 and the fan 203 to work according to a preset program. After the fan 203 starts, it pumps the external air filtered by the filter screen 204 into the interior of the cylinder body 201. Subsequently, the heating wire 202 starts to heat the air. The heated hot air enters the interior of the mounting frame 102 through the through holes on the circuit board in the core module 106 to evaporate and remove the mist on the surface of the protective lens 103 and the core module 106. The excess hot air in the mounting frame 102 flows into the ventilation cavity 205 through the circuit board notch and finally is discharged outside the device through the exhaust slot 206. Through the continuous collaborative work of the fan 203 and the heating wire 202, the water mist inside the protective lens 103 and the mounting frame 102 can be effectively removed, keeping the interior of the device dry and ensuring the normal and stable operation of each component. When the working time of the fan 203 and the heating wire 202 reaches the preset duration, the controller 107 automatically cuts off the power supply and stops their operation, realizing intelligent energy-saving control.

[0038] Embodiment 2: On the basis of Embodiment 1, as Figures 5-10 shown, it further includes a rotating shaft 301, a rotating block 302, a rotating disk 303, a storage frame 304, a return spring 305 and a wind guide wheel 306. The right side of the cylinder body 201 is rotatably connected to a rotating block 302. A rotating shaft 301 is splined to the rotating block 302. This connection method can not only effectively transmit torque but also allow the rotating shaft 301 to axially move within the rotating block 302. The right side of the rotating shaft 301 is connected to a rotating disk 303. The outside of the rotating disk 303 is rotatably connected to a storage frame 304 internally storing a desiccant. The desiccant is a montmorillonite desiccant, which has the characteristics of fast adsorption speed and strong adsorption capacity. In an environment with a relative humidity of 50%, the effective service life of the montmorillonite desiccant can reach 2 - 3 years. The storage frame 304 is rotatably connected to the rotating shaft 301. A plurality of scraping strips are adhesively bonded at intervals along the circumference on the outside of the rotating disk 303. The scraping strips are made of wear-resistant and elastic materials. These scraping strips are in close contact with the inner wall of the storage frame 304. A plurality of uniformly distributed through holes are provided on the outer wall of the storage frame 304. The size and number of the through holes are optimized to ensure both air circulation and prevent the leakage of desiccant particles. The right end of the rotating shaft 301 is welded with a wind guide wheel 306. The wind guide wheel 306 is rotatably connected to the right side wall of the storage frame 304. A return spring 305 is connected between the left side of the rotating disk 303 and the rotating block 302. The return spring 305 is sleeved on the rotating shaft 301. In the initial state, the storage frame 304 and the wind guide wheel 306 are in close contact with the right port of the cylinder body 201, forming a good sealing state to effectively prevent external moisture from entering the cylinder body 201.

[0039] As Figures 6-10As shown in the figure, it further includes a guide rod 401, a sealing ring 402, a gear 403, a fixed rack 404 and a rack rod 405. Rack rods 405 are respectively welded to the upper and lower sides of the storage frame 304. The two rack rods 405 are slidably connected to the upper and lower sides inside the housing 101. Gears 403 are respectively rotatably connected to the positions near the two rack rods 405 inside the housing 101 through mounting seats. The gears 403 are meshed with the corresponding rack rods 405. A plurality of guide rods 401 are circumferentially slidably connected to the position of the housing 101 located in the ventilation chamber 205. A sealing ring 402 is commonly connected between the right ends of these guide rods 401. The sealing ring 402 is made of silicone rubber with good elasticity and sealing performance. In the initial state, the sealing ring 402 seals the passage of the ventilation chamber 205 flowing through the exhaust slot 206, blocking the air flow passage between the ventilation chamber 205 and the outside. Fixed racks 404 are respectively welded to the uppermost and lowermost guide rods 401. The fixed racks 404 are meshed with the corresponding gears 403, and the transmission of force and motion is realized through the transmission of the gears 403.

[0040] The desiccant stored in the storage frame 304 can absorb the moisture inside the housing 101. When the controller 107 receives the demisting command, the fan 203 is started. The fan 203 forms a negative pressure area inside the cylinder 201. The external air is filtered by the filter 204 under the drive of the pressure difference and enters the cylinder 201. When the air flows through the wind guide wheel 306, according to the momentum moment theorem, the airflow generates a tangential force on the blades of the wind guide wheel 306, driving the wind guide wheel 306 to rotate. The wind guide wheel 306 drives the rotor The shaft 301 rotates. Since the shaft 301 and the rotating block 302 are splined, the rotation of the shaft 301 will drive the rotating block 302 to rotate synchronously. At the same time, the rotating disk 303 rotates together with the shaft 301, and the scraper on it closely adheres to the inner wall of the storage frame 304 to make a circular motion. Through this mechanical stirring effect, the scraper constantly moves the desiccant in the storage frame 304, so that the desiccant is fully in contact with the moisture. According to the principle of adsorption dynamics, the moisture inside the housing 101 is efficiently absorbed. Under the continuous action of the airflow, the desiccant is guided The impeller 306 is subjected to axial thrust, and the guide wheel 306 will move to the left while rotating, driving the rotating shaft 301, the rotating disk 303 and the storage frame 304 to overcome the elastic force of the return spring 305 and move to the left. The return spring 305 produces elastic deformation and stores elastic potential energy, and the rotating block 302 will remain in place. At this time, the storage frame 304 and the guide wheel 306 no longer block the right port of the cylinder 201, and the air can smoothly enter the cylinder 201. The axial movement of the storage frame 304 transmits power through the rack rod 405. The rack rod 405 is meshed with the gear 403, which will drive the gear 403 to rotate. The gear 403 then meshes with the fixed rack 404, driving the fixed rack 404 to make a linear motion, so as to drive the guide rod 401 and the sealing ring 402 to move to the left, thereby releasing the seal of the channel between the ventilation chamber 205 and the exhaust slot 206, and forming an air exhaust channel. In this process, the hot and humid air in the ventilation chamber 205 is quickly discharged through the exhaust slot 206 under the action of the pressure gradient generated by the fan 203, thereby achieving efficient defogger.

[0041] When the defog operation is completed and the fan 203 stops running, the air guide wheel 306, the rotating shaft 301 and other related components stop rotating, and the system enters the reset stage. The reset spring 305 releases elastic potential energy, generating a restoring force to push the rotating disk 303, the storage frame 304, the rotating shaft 301 and the air guide wheel 306 to move to the right to reset. The storage frame 304 and the air guide wheel 306 re-seal the right port of the cylinder 201 to block the entry of external moisture. At the same time, the rack rod 405 drives the gear 403 to reverse, so as to drive the fixed rack 404, the guide rod 401 and the sealing ring 402 to move to the right, thereby re-closing the channel of the ventilation cavity 205 flowing through the exhaust slot 206, effectively preventing external moisture and rainwater from invading the cylinder 201 and the interior of the installation frame 102, and ensuring the stable operation of the core module 106 in a dry environment.

[0042] like Figures 11-14As shown, it further includes a water collecting frame 502, a solenoid valve 503 and a sprinkler 504. The middle part of the top of the top frame 105 is designed as a concave structure, which is conducive to the collection of rainwater. A water collecting hole 501 is opened on the left side of the concave structure. A filter screen is installed at the water collecting hole 501, and the filter screen can effectively prevent impurities such as leaves and dust from entering the water collecting system. The left side of the bottom of the top frame 105 is connected to a water collecting frame 502, and the water collecting frame 502 communicates with the water collecting hole 501, and can collect and store the rainwater flowing in through the water collecting hole 501. A solenoid valve 503 is installed on the left side of the water collecting frame 502, and a sprinkler 504 is installed at the bottom of the solenoid valve 503. The sprinkler 504 penetrates through the installation frame 102, and its spraying direction is precisely oriented towards the protective lens 103. Both the solenoid valve 503 and the sprinkler 504 are electrically connected to the controller 107 through wires, facilitating the controller 107 to precisely control them.

[0043] As Figures 11-15 shown, it further includes a motor 601, a first scraper 602 and a second scraper 603. The motor 601 is installed on the lower right side of the protective lens 103 by bolts. The motor 601 is located inside the installation frame 102 to protect the motor 601 from the external environment. The output shaft of the motor 601 penetrates through the left side of the protective lens 103 and is connected to the first scraper 602. A second scraper 603 is slidably connected to the first scraper 602. The first scraper 602 and the second scraper 603 are in close contact with the wall surface of the protective lens 103. A guide groove 604 is opened at the position on the lower left side of the protective lens 103 outside the first scraper 602. A protrusion is provided on the second scraper 603, and the protrusion is slidably matched with the guide groove 604. The motor 601 is electrically connected to the controller 107.

[0044] When the monitoring camera is installed outdoors and encounters rainy weather, rainwater will fall on the top frame 105. Due to the concave structure design in the middle of the top of the top frame 105, the rainwater will temporarily accumulate in the concave area and then flow into the water collecting frame 502 through the water collecting hole 501. The filter screen at the water collecting hole 501 will filter the impurities carried in the rainwater to ensure that the rainwater flowing into the water collecting frame 502 is relatively clean and convenient for subsequent use.

[0045] When there is a lot of dust and water marks on the surface of the protective lens 103 after the monitoring camera has been used for a long time, a cleaning instruction can be sent to the controller 107 through the remote control system. After receiving the instruction, the controller 107 first controls the solenoid valve 503 to open and simultaneously starts the nozzle 504. The nozzle 504 uses the siphon principle or an internal micro water pump to pump out the rainwater in the water collection frame 502 and sprays the rainwater on the surface of the protective lens 103 at an appropriate pressure and flow rate. After completing the rainwater spraying operation, the controller 107 automatically closes the nozzle 504 and the solenoid valve 503. Then, the controller 107 controls the motor 601 to start, and the output shaft of the motor 601 starts to rotate, driving the first scraper 602 and the second scraper 603 to rotate synchronously. Since the second scraper 603 is in sliding fit with the guide groove 604, during the rotation process, the second scraper 603 will gradually extend according to the groove direction of the guide groove 604, thereby expanding the contact area with the protective lens 103. During the rotation process, the first scraper 602 and the second scraper 603 can effectively scrape and clean the accumulated water and dust on the surface of the protective lens 103. When the first scraper 602 and the second scraper 603 complete one round of cleaning, the controller 107 controls the motor 601 to reverse, so that the first scraper 602 and the second scraper 603 return to their initial positions. Subsequently, the motor 601 automatically stops running, and the entire cleaning process ends.
