A spherical camera for traffic management

Abstract

This invention discloses a spherical camera for traffic management, relating to the field of traffic camera technology. It includes a mounting base, a protective housing, and a detection controller. The mounting base is symmetrically fixedly connected to the outer wall of the protective housing. The detection controller is fixedly installed at the bottom of the protective housing.

Description

Technical Field

[0001] This invention relates to the field of traffic camera technology, specifically a spherical camera for traffic management. Background Technology

[0002] Traffic cameras are specialized video recording devices used for traffic management, monitoring, and law enforcement. They primarily capture and record traffic conditions on and around roads, providing evidence for maintaining traffic order, investigating violations, and handling accidents. Their main uses include automatically recording traffic violations such as running red lights, speeding, crossing solid lines, not driving in designated lanes, illegal parking, and failing to yield to pedestrians using high-definition imaging and intelligent algorithms (such as license plate recognition and trajectory analysis). These records serve as evidence for law enforcement. They also monitor real-time traffic and pedestrian flow, using video analysis technology to statistically analyze data such as traffic volume, speed, and congestion levels, providing reference for traffic signal control and road network planning (e.g., intelligently adjusting traffic light timings to alleviate congestion). Furthermore, they record images before and after traffic accidents, clearly reconstructing the accident process to help traffic police determine responsibility; and can also trace the trajectory of hit-and-run vehicles.

[0003] Chinese patent publication number CN113259555B discloses a "self-cleaning spherical camera for traffic management," comprising a main body, a mounting base, a PTZ camera, a power motor, a large gear, a protective cover, a gear ring, an upper liquid infusion chamber, a liquid storage tank, a pressure sensor, a guide strip, a support frame, a transmission rod, and a self-cleaning component. A horizontal mounting base is fixed to the upper rear end of the main body, and a vertical PTZ camera is fixed to the bottom end of the main body. This invention uses a rack and pinion to drive the small gear, thereby connecting the lower and upper liquid infusion chambers and allowing the wiper to rotate to the bottom of the protective cover. This allows liquid to drain through the upper and lower liquid infusion chambers from the cleaning hole. The pressure of the liquid energizes the pressure sensor to power the motor, causing the protective cover to rotate counterclockwise. This rotation, combined with the liquid draining from the cleaning hole and the wiper sponge, cleans the outer wall of the protective cover.

[0004] The above description of the device still has shortcomings, mainly including:

[0005] 1. This device mainly relies on a storage tank to collect rainwater and dew as cleaning liquid. However, the capacity of the storage tank is limited. In areas with prolonged drought or little rainfall, it may not be able to replenish enough liquid in time, causing the cleaning function to fail to function properly. In addition, if the liquid in the storage tank is not used for a long time, bacteria or impurities may grow, affecting the cleaning effect and even causing corrosion to the camera components.

[0006] 2. During the cleaning process, although the patent has designed a corresponding structure to minimize the impact on the monitoring screen, cleaning components such as windshield wipers may still briefly obstruct the lens during movement, causing the monitoring screen to become temporarily blurry or missing. This may affect the monitoring effect and data integrity in some scenarios that require continuous and stable monitoring.

[0007] Therefore, a spherical camera for traffic management is proposed. Summary of the Invention

[0008] The purpose of this invention is to provide a spherical camera for traffic management to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a spherical camera for traffic management, comprising a mounting base, a protective housing, and a detection controller. The mounting base is symmetrically and fixedly connected to the outer wall of the protective housing, the detection controller is fixedly installed at the bottom of the protective housing, a moisture-proof cleaning mechanism is provided on the top of the protective housing, and a drive adjustment mechanism is provided inside the protective housing.

[0010] The drive adjustment mechanism includes a protective shell fixedly connected to the inner wall of the bottom end of the protective shell, and a drive rod symmetrically and rotatably connected to the bottom end of the protective shell. A camera is fixedly connected between the two drive rods.

[0011] The moisture-proof cleaning mechanism includes a filter plate fixedly connected to the top of the protective housing. Fixed shells are symmetrically fixedly connected to the side wall of the filter plate. Fan blades are rotatably arranged inside the filter plate.

[0012] Furthermore, the drive adjustment mechanism also includes an annular sleeve rotatably connected to the outer wall of the drive rod, a transparent glass shell fixedly connected between the two annular sleeves, inclined toothed plates symmetrically fixedly connected to the side wall of the transparent glass shell, helical gears meshing on the outer wall of the inclined toothed plates, a first transmission rod symmetrically rotatably connected through the interior of the protective shell, a transmission wheel fixedly connected to the top end of the first transmission rod, a second transmission rod rotatably connected to the top end of the inner cavity of the first filter tank plate, and a conveyor belt drivingly connecting the second transmission rod and the transmission wheel.

[0013] Furthermore, the transmission rod is fixedly connected to the helical gear.

[0014] Furthermore, the two conveyor belts at the top of the two drive rods are not on the same horizontal plane, and the size of the camera is adapted to the transparent glass shell.

[0015] Furthermore, the transmission wheel is rotatably connected to the top of the inner cavity of the fixed shell.

[0016] Furthermore, the transmission rod two is electrically connected to the detection controller, and the transmission rod two is fixedly connected to the fan blade.

[0017] Furthermore, the moisture-proof cleaning mechanism also includes a rectangular trough plate fixedly connected to the lower surface of the filter trough plate. Several ventilation holes are symmetrically opened on the side wall of the rectangular trough plate. A water storage trough plate is fixedly connected to the inner wall of the rectangular trough plate. A second filter trough plate is fixedly connected to the top of the inner cavity of the water storage trough plate. A semiconductor cooling chip is fixedly connected to the middle of the inner cavity of the water storage trough plate. A first guide trough plate and a second guide trough plate are symmetrically fixedly connected to the bottom end of the rectangular trough plate. A heating rod is fixedly connected inside the first guide trough plate. A dryer is fixedly connected to the end of the first guide trough plate away from the rectangular trough plate. A cleaning brush is fixedly connected to the end of the second guide trough plate away from the rectangular trough plate.

[0018] Furthermore, the vent is located between the second filter plate and the thermoelectric cooler, and the thermoelectric cooler is electrically connected to the detection and control device.

[0019] Furthermore, the second guide plate is internally connected to the water storage tank plate, the heating rod is electrically connected to the detection controller, and the interior of the rectangular trough plate is connected to the interior of the protective shell through a vent hole.

[0020] Furthermore, the transparent glass shell is adapted to the size of the dryer, the bottom end of the rectangular groove plate is fixedly connected to the top of the protective shell, and the filter groove plate is composed of an external activated carbon support and a gauze in the middle.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By adapting the transparent glass shell to the size of the camera and through the meshing transmission of the inclined toothed plate and helical gear, the transparent glass shell can be rotated, allowing the contaminated part to be moved into the protective shell for cleaning. The cleaned part is simultaneously rotated out to the shooting position, without obstructing the camera's monitoring field of view, ensuring continuous and stable footage. In addition, the cleaning brush and dryer only work on the non-monitoring area of ​​the transparent glass shell that is moved into the protective shell. Combined with the precise transmission control of the drive wheel and conveyor belt, the cleaning action avoids interference with the real-time monitoring footage, ensuring the integrity of the video data required for traffic management.

[0023] 2. By employing a semiconductor cooling chip to liquefy the filtered air, combined with the dual filtration of activated carbon adsorbing impurities and gauze filtering particles in filter plate one and filter plate two, clean liquid can be stably obtained from the air, unaffected by weather or geographical location, ensuring liquid supply even in arid and low-rainfall areas. In addition, the water storage plate, together with guide plate one and guide plate two, achieves orderly storage and distribution of liquid, and the filtered liquid has high purity, avoiding problems such as bacterial growth or impurities corroding components. Through the airflow circulation design of fan blades and vents, basic cleaning can be achieved by heating the airflow when the liquid is insufficient, ensuring the continuous effectiveness of the cleaning function.

[0024] 3. The airflow inside the first guide plate is heated by the heating rod. After being discharged by the dryer, it can quickly dry the residual water stains on the surface of the transparent glass shell, avoiding the water stains from affecting the clarity of the picture after cleaning. In addition, when the equipment is running in reverse, the hot airflow can dry and clean the second filter plate, preventing it from being blocked due to moisture. At the same time, it dehumidifies the inside of the equipment, reduces the risk of component corrosion, and extends the service life of the equipment. Attached Figure Description

[0040] Preferably, the moisture-proof cleaning mechanism 3 further includes a rectangular groove plate 304 fixedly connected to the lower surface of the filter plate 301. The bottom end of the rectangular groove plate 304 is fixedly connected to the top of the protective shell 201. Several ventilation holes 305 are symmetrically opened on the side wall of the rectangular groove plate 304. The interior of the rectangular groove plate 304 is connected to the interior of the protective shell 102 through the ventilation holes 305. A water storage plate 306 is fixedly connected to the inner wall of the rectangular groove plate 304.

The bottom end of the rectangular plate 304 is symmetrically fixedly connected to the flow guide plate 1 309 and the flow guide plate 2 312.

The end of the flow guide plate 2 312 away from the rectangular plate 304 is fixedly connected to the cleaning brush 313.

[0041] It should be noted that the dryer 311 has a sponge block inside.

[0042] The working principle of the above implementation is as follows:

[0043] The operation steps are as follows:

[0044] The working steps of the moisture-proof cleaning mechanism 3 are as follows:

[0045] When the device operates in rainy weather, rainwater carrying dust particles can easily adhere to the camera, affecting the clarity of images and videos. Therefore, the device uses a detection controller to monitor the camera 203 in real time. When water stains and dust are detected on the surface of the camera 203, the detection controller controls the transmission rod 211 to rotate on the top of the inner wall of the filter plate 301. Simultaneously, the detection controller controls the semiconductor cooling chip 308 and the heating rod 310 to start working synchronously, causing the transmission rod 211 to drive the fan blade 303 to rotate synchronously on the filter plate 301. Inside the filter plate 301, the fan blades 303 drive the air outside the filter plate 301 through the filter plate 301 for preliminary filtration before entering the bottom of the fan blades 303. This allows the air inside the filter plate 301 to enter the water storage plate 306. As the air moves downwards inside the water storage plate 306, it comes into contact with the filter plate 307. The activated carbon in the filter plate 307 absorbs organic pollutants, odors, and some small molecules from the air. At the same time, the gauze in the middle of the filter plate 307 removes dust particles. In the filtration process, after air is absorbed and filtered through the second filter plate 307, it enters the bottom of the filter plate 307, allowing the filtered air to come into contact with the thermoelectric cooler 308. Under the action of the thermoelectric cooler 308, the air is liquefied and flows into the bottom of the water storage plate 306 under the guidance of the thermoelectric cooler 308. The liquefied air then flows through the water storage plate 306 into the interior of the second guide plate 312, and then into the sponge block inside the cleaning brush 313, where the sponge block absorbs the air. During the rotation of the heating rod 310 and the fan blade 303, part of the airflow filtered by the second filter plate 307 enters the interior of the rectangular slot plate 304 through the vent 305, and then enters the interior of the first guide plate 309 through the rectangular slot plate 304. The heating rod 310 installed inside the first guide plate 309 heats the airflow and then discharges it through the dryer 311. The dust and water stains on the outer wall of the transparent glass shell 204 are then wiped by the cleaning brush 313. The dryer 311 dries the water stains remaining after wiping by the discharged hot air.

[0046] The working steps of the drive adjustment mechanism 2 are as follows:

[0047] As shown above, when the transmission rod 211 rotates on the inner wall of the filter tank plate 301, it drives the transmission belt 210 connected to it to rotate synchronously. The transmission belt 210 drives the transmission wheel 209 connected to it to rotate synchronously inside the fixed shell 302. The transmission wheel 209 drives the transmission rod 208 to rotate synchronously inside the protective shell 201. The transmission rod 208 drives the helical gear 207 to rotate synchronously. The helical gear 207 drives the inclined toothed plate 206 that meshes with it. The synchronous rotation causes the inclined toothed plate 206 to drive the transparent glass shell 204 to rotate, which in turn causes the transparent glass shell 204 to drive the annular sleeve 205 to rotate on the outer wall of the drive rod 202. This causes the transparent glass shell 204 to rotate inside the protective shell 201, and the contaminated part of the transparent glass shell 204 to rotate into the protective shell 102. The dryer 311 and the cleaning brush 313 clean its outer surface, and the cleaned part inside the protective shell 201 rotates to the position where the camera 203 needs to take pictures.

[0048] By adapting the size of the transparent glass shell 204 to the camera 203, and through the meshing transmission of the inclined toothed plate 206 and the helical gear 207, the transparent glass shell 204 can be rotated, allowing the contaminated part to be moved into the protective shell 102 for cleaning. The cleaned part is simultaneously moved out to the shooting position, without obstructing the monitoring field of the camera 203, ensuring continuous and stable images. In addition, the cleaning brush 311 and the dryer 313 only work on the non-monitoring area of ​​the transparent glass shell 204 that is moved into the protective shell 102. With the precise transmission control of the transmission wheel 209 and the conveyor belt 210, the cleaning action avoids interference with the real-time monitoring image, ensuring the integrity of the video data required for traffic management.

[0049] When the rain stops, the controller controls the transmission rod 211 to rotate in the reverse direction, and simultaneously controls the semiconductor cooling chip 308 to stop working. This causes the transmission rod 211 to drive the fan blade 303 to rotate in the reverse direction inside the filter plate 301. During the reverse rotation of the fan blade 303, the airflow moves in the reverse direction, causing the airflow at the bottom of the dryer 311 to enter the guide plate 309. After being heated by the heating rod 310, the airflow enters the rectangular plate 304, and then enters the water storage plate 306 through the vent 305. The heated airflow... The air enters the bottom of filter plate 2 307, is filtered through filter plate 2 307, and finally exits the equipment through rectangular plate 304 and filter plate 1 301. In addition, when the hot air passes through filter plate 2 307, the dust particles with high humidity inside filter plate 2 307 are heated, and the dust particles inside filter plate 2 307 are discharged together under the action of airflow, ensuring the air permeability of filter plate 2 307. The heated airflow dries the dust particles as it flows inside the equipment, avoiding corrosion and other problems caused by high humidity inside the equipment.

[0050] By employing a semiconductor cooling chip 308 to liquefy the filtered air, combined with the dual filtration of activated carbon adsorbing impurities and gauze filtering particles through filter plate 301 and filter plate 307, clean liquid can be stably obtained from the air, unaffected by weather or geographical location, ensuring liquid supply even in arid and low-rainfall areas. Furthermore, the water storage plate 306, in conjunction with the flow guide plates 309 and 312, enables orderly storage and distribution of the liquid, and the filtered liquid has high purity, avoiding problems such as bacterial growth or impurities corroding components. Through the airflow circulation design of the fan blades 303 and vents 305, basic cleaning can be achieved through heated airflow when the liquid is insufficient, ensuring the continuous effectiveness of the cleaning function.

[0051] The airflow inside the guide plate 309 is heated by the heating rod 310. After being discharged through the dryer 311, it can quickly dry the residual water stains on the surface of the transparent glass shell 204, avoiding the water stains from affecting the clarity of the picture after cleaning. In addition, when the equipment is running in reverse, the hot airflow can dry and clean the filter plate 307, preventing it from being blocked due to moisture. At the same time, it dehumidifies the inside of the equipment, reduces the risk of component corrosion, and extends the service life of the equipment.
