Description

Technical Field

[0001] The invention relates to the technical field of road design, in particular to a traffic flow monitoring device for road design. Background Art

[0002] A traffic flow monitoring device is a device used to monitor and analyze vehicle driving conditions on the road in real time. It provides support for traffic management, road planning and traffic safety by collecting traffic flow data and conducting statistical analysis.

[0003] Existing traffic flow monitoring devices are usually composed of sensors and cameras, which are erected at high places or set up next to road green belts through poles. During the use of the camera, its internal components will generate accumulated heat. At the same time, during use in summer, direct sunlight will intensify the generation of internal heat, which will affect the use of the camera. Summary of the invention

[0004] The object of the present invention is to provide a traffic flow monitoring device for road design to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a traffic flow monitoring device designed for roads, comprising a housing, a support frame is installed on the outer wall of the housing, and a camera is installed on the upper surface of the support frame;

[0007] A plurality of guide grooves are arranged on the outer wall of the camera;

[0008] The top diameter of the shell is larger than the bottom diameter, and the shell forms a channel;

[0009] A filter ring net is installed at the top port of the support frame, and a flow guide component for guiding the airflow is installed on the inner side of the filter ring net;

[0010] The guide assembly is driven by the wind force generated by the flow of vehicles. When the wind force drives the guide assembly to operate, the airflow passes through the filtering annular net, passes through the inside of the shell, and flows from top to bottom to the inside of the plurality of guide grooves for heat exchange;

[0011] A conical top is installed on the top of the guide component. The bottom diameter of the conical top is larger than the diameter of the filtering annular net. The conical top is conical, which is convenient for guiding rain and snow to the outside of the shell.

[0012] In this embodiment, the purpose of the above-mentioned setting is to install the device beside the road green belt. When the vehicle is driving fast, the vehicle flow will generate wind force. This wind force serves as the starting power source of the airflow in the whole system. The guide component is located on the inner side of the filter ring net. When the wind drives the guide component to operate, it starts to guide the airflow. The airflow first passes through the filter ring net. The filter ring net can perform preliminary filtering on the incoming airflow to prevent larger impurities from entering. The filtered airflow enters the interior of the shell. The top diameter of the shell is larger than the bottom diameter to form a channel. The airflow flows from top to bottom along this channel. The airflow is more concentrated when it reaches the bottom of the shell and the top of the camera.

[0013] Finally, the airflow flows to the inner side of several guide grooves on the outer wall of the camera, where heat exchange is performed, thereby regulating the temperature of the camera.

[0014] A conical top is installed on the top of the guide component, and its bottom diameter is larger than the diameter of the filter ring net and is conical. When encountering rainy and snowy weather, the shape of the conical top can conveniently guide the rain and snow to the outside of the shell, preventing rain and snow from entering the inside of the device, thereby protecting the internal guide component, filter ring net, camera and other components, ensuring that the entire device can work normally. At the same time, the setting of the conical top and the shell has a sunshade effect on the top of the camera to prevent it from being directly exposed to the sun during work in summer.

[0015] Further, the diversion assembly includes a rotating shaft and a connecting plate, the connecting plate is installed on the inner wall of the filter ring net, the rotating shaft passes through the connecting plate and is rotatably connected, the outer wall of the rotating shaft is connected with a plurality of connecting through pipes, and one end of the connecting through pipe is connected with a diversion bucket;

[0016] A fan blade is installed at one end of the rotating shaft and is located on the inner side of the shell, and the bottom port of the rotating shaft faces the top of the camera.

[0017] In this embodiment, the purpose of the above arrangement is that the wind force generated by the vehicle flow acts on the concave inner wall of the diversion bucket, and the fan blade is installed at one end of the rotating shaft and is located on the inner side of the shell. The wind force drives the diversion bucket to rotate, thereby driving the rotating shaft to rotate;

[0018] The rotating shaft passes through the connecting plate and is rotatably connected thereto. The connecting plate is mounted on the inner wall of the filtering annular net to support the rotating shaft.

[0019] As the shaft rotates, several connecting pipes connected on its outer wall also rotate. A fan blade is installed at one end of the shaft. The fan blade rotates to pour the airflow passing through the filter ring net.

[0020] Under the action of the guide component, the airflow first passes through the filter ring net, and after the impurities are filtered out by the filter ring net, it enters the shell, flows from top to bottom along the shell, and finally flows to the inner side of the guide groove on the outer wall of the camera for heat exchange;

[0021] The bottom port of the rotating shaft faces the top of the camera. This structural design is that when the wind acts on the concave inner wall of the diversion bucket, a small amount of air flows through the connecting pipe. The connecting pipe has a smaller port to avoid weakening the wind acting on the concave inner wall of the diversion bucket. Then, the wind flows through the bottom port of the rotating shaft, which helps to more accurately guide the airflow to the diversion groove of the camera to achieve more effective heat exchange.

[0022] Furthermore, a brush plate for cleaning the surface of the filter annular net is installed on the outer wall of the rotating shaft.

[0023] In this embodiment, the purpose of the above arrangement is that when the shaft rotates, the brush plate installed on its outer wall also rotates. Since the brush plate is close to the surface of the filter ring net, when the brush plate rotates, the surface of the filter ring net will be cleaned.

[0024] As the airflow continuously passes through the filter ring net, dust, impurities, etc. may be filtered on the surface of the filter ring net. When the device is used for a long time, it will affect the filtering effect and the smoothness of the airflow. The rotation of the brush plate can clean these impurities in time, maintain the good filtering performance of the filter ring net, and ensure that the airflow can continuously and smoothly pass through the filter ring net into the interior of the shell.

[0025] Furthermore, a second bevel gear is installed at the bottom of the rotating shaft, a transmission assembly is connected to the outer wall of the bottom of the second bevel gear, two arc-shaped brush plates are slidably connected to the outer wall of the camera, and the transmission assembly is connected to the arc-shaped brush plates and drives the two arc-shaped brush plates;

[0026] A spray assembly for spraying liquid on the surface of the camera is installed on the bottom outer wall of the camera, and a liquid storage box for supplying liquid to the spray assembly is installed on the bottom outer wall of the shell.

[0027] In this embodiment, the purpose of the above arrangement is that when the rotating shaft rotates, the second bevel gear installed at the bottom thereof also rotates accordingly, the second bevel gear is connected to the transmission assembly, the second bevel gear drives the transmission assembly to operate, the transmission assembly drives the two arc-shaped brush plates to move up and down repeatedly, and the outer wall of the camera is slidably connected with two arc-shaped brush plates. Under the drive of the transmission assembly, the arc-shaped brush plates will slide on the outer wall of the camera to clean the outer wall of the camera, remove dust and dirt that may be attached to the outer wall of the camera, and keep the camera's shooting field of view clear;

[0028] The liquid storage box is installed on the bottom outer wall of the shell and is used to store cleaning liquid. When the camera surface needs to be cleaned, the liquid storage box provides cleaning liquid to the spray assembly;

[0029] The spray assembly is installed on the bottom outer wall of the camera. After the liquid storage box provides cleaning liquid to the spray assembly, the two arc-shaped brush plates move downward, pushing the spray assembly to run. The spray assembly sprays the cleaning liquid onto the surface of the camera, and cooperates with the cleaning of the arc-shaped brush plates. Under the action of hydraulic pressure, the cleaning liquid is sprayed out first, and the cleaning liquid is sprayed on the surface of the camera first, followed by the arc-shaped brush plates falling down to sweep away the dirt, thereby more effectively cleaning the surface of the camera.

[0030] Furthermore, the transmission assembly includes a first bevel gear and a connecting shaft, both ends of the connecting shaft are respectively connected to the inner wall of the shell, two first bevel gears are symmetrically installed on the outer wall of the connecting shaft, and the two first bevel gears are respectively meshed with the second bevel gear.

[0031] In this embodiment, the purpose of the above arrangement is that when the shaft rotates, the second bevel gear installed at the bottom of the shaft rotates accordingly;

[0032] The second bevel gear is meshed with the two first bevel gears respectively. Since the two first bevel gears are symmetrically mounted on the outer wall of the connecting shaft, when the second bevel gear rotates, the two first bevel gears will be driven to rotate.

[0033] Both ends of the connecting shaft are connected to the inner wall of the shell respectively, playing the role of supporting the first bevel gear and maintaining the stability of the first bevel gear during the rotation process.

[0034] Furthermore, the outer walls at both ends of the connecting shaft are rotatably connected with rotating disks, a push rod is connected between the rotating disk and the first bevel gear, and both ends of the push rod are rotatably connected with the first bevel gear and the rotating disk respectively;

[0035] The bottom of the push rod is rotatably connected with a connecting block, and the connecting block is connected with the arc-shaped brush plate.

[0036] In this embodiment, the purpose of the above arrangement is that when the first bevel gear rotates, the two ends of the push rod are respectively rotatably connected with the first bevel gear and the rotating disk, and the rotating disk is rotatably connected to the outer wall of the connecting shaft. As the first bevel gear rotates, the top end of the push rod makes a circular motion between the first bevel gear and the rotating disk, and there is a moving drop at the top end;

[0037] The bottom of the push rod is rotatably connected to a connecting block, and the bottom of the push rod is connected to the arc-shaped brush plate through the connecting block. When the top and bottom ends of the push rod move up and down, the two push rods respectively drive the arc-shaped brush plate to slide up and down on the guide groove of the outer wall of the camera, thereby realizing the cleaning function of the arc-shaped brush plate on the outer wall of the camera.

[0038] Furthermore, the spray assembly includes a telescopic tube, a connecting ring, a spray pipe and a one-way valve;

[0039] The connecting ring is installed on the bottom outer wall of the camera, a plurality of the nozzles are connected to the upper surface of the connecting ring, the two telescopic tubes are respectively connected to the two ends of the connecting ring, the two telescopic tubes are respectively connected to the liquid storage box, and the one-way valve is installed at the bottom of the telescopic tube.

[0040] In this embodiment, the purpose of the above-mentioned setting is that when the cleaning liquid in the liquid storage box is not working, the one-way valve prevents the cleaning liquid in the telescopic tube from flowing to the connecting ring, and the cleaning liquid flows into and fills the telescopic tube by itself. When the telescopic tube is squeezed by the arc-shaped brush plate, under the action of pressure, the cleaning liquid will flow through the telescopic tube to the connecting ring, and the connecting ring will evenly distribute the cleaning liquid to each nozzle. A number of small holes are set on the top of the nozzle, and the cleaning liquid is sprayed onto the surface of the camera in the form of a spray through the several small holes.

[0041] Furthermore, the upper surface of the liquid storage box is connected to a liquid inlet pipe.

[0042] In this embodiment, the purpose of the above arrangement is to add cleaning liquid into the interior of the liquid storage box.

[0043] Furthermore, the plurality of nozzles and the two arc-shaped brush plates are in the same vertical direction.

[0044] In this embodiment, the purpose of the above-mentioned arrangement is to coordinate the cleaning of the nozzle with that of the arc-shaped brush plate to maintain consistency in the cleaning of the camera.

[0045] Furthermore, the one-way valve includes a valve body, a valve core and a spring. The valve body is installed on the bottom inner wall of the telescopic tube and is connected. The bottom of the valve body is connected to a connecting ring. The spring is installed on the inner side of the bottom of the valve body. The valve core is slidably connected to the top inner wall of the valve body.

[0046] In this embodiment, the purpose of the above arrangement is that when the telescopic tube is squeezed by the arc-shaped brush plate, the cleaning liquid will push the valve core extrusion spring under the action of pressure to open the top port of the valve body, and the cleaning liquid will flow through the valve body to the connecting ring.

[0047] The present invention has the following beneficial effects:

[0048] (1) The present invention installs the device beside the road green belt by setting the guide component and the guide groove. When the vehicle is driving fast, the vehicle flow will generate wind force, which serves as the starting power source of the airflow in the whole system. The guide component is located on the inner side of the filter ring net. When the wind drives the guide component to operate, it starts to guide the airflow. The airflow first passes through the filter ring net. The filter ring net can perform preliminary filtering on the incoming airflow to prevent larger impurities from entering. The filtered airflow enters the shell. The top diameter of the shell is larger than the bottom diameter to form a channel. The airflow flows from top to bottom along this channel. When the airflow reaches the bottom of the shell and the top of the camera, it is more concentrated. Finally, the airflow flows to the inner side of several guide grooves on the outer wall of the camera, where heat exchange is performed, thereby playing a role in regulating the temperature of the camera.

[0049] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] This embodiment is a traffic flow monitoring device designed for a road, such as Figure 1 - Figure 4 As shown, it comprises a shell 1, a support frame 2 is mounted on the outer wall of the shell 1, and a camera 9 is mounted on the upper surface of the support frame 2;

[0064] A plurality of guide grooves 901 are provided on the outer wall of the camera 9;

[0065] The top diameter of the shell 1 is larger than the bottom diameter, and the shell 1 forms a channel;

[0066] A filter ring net 5 is installed at the top port of the support frame 2, and a flow guide component 3 for guiding the airflow is installed on the inner side of the filter ring net 5;

[0067] The guide assembly 3 is driven by the wind force generated by the flow of vehicles. When the wind force drives the guide assembly 3 to operate, the airflow passes through the filtering annular net 5, passes through the inside of the shell 1, and flows from top to bottom to the inside of the plurality of guide grooves 901 for heat exchange.

[0068] A conical top 4 is installed on the top of the guide component 3 . The bottom diameter of the conical top 4 is larger than the diameter of the filtering annular net 5 . The conical top 4 is conical, which facilitates guiding rain and snow to the outside of the shell 1 .

[0069] In this embodiment, the purpose of the above-mentioned setting is to install the device beside the road green belt. When the vehicle is driving fast, the vehicle flow will generate wind force, which serves as the starting power source of the airflow in the whole system. The guide component 3 is located on the inner side of the filter ring net 5. When the wind drives the guide component 3 to operate, it starts to guide the airflow. The airflow first passes through the filter ring net 5. The filter ring net 5 can perform preliminary filtering on the incoming airflow to prevent larger impurities from entering. The filtered airflow enters the interior of the shell 1. The top diameter of the shell 1 is larger than the bottom diameter to form a channel. The airflow flows from top to bottom along this channel. When the airflow reaches the bottom of the shell 1 and the top of the camera 9, it is more concentrated.

[0070] Finally, the airflow flows to the inner side of the plurality of guide grooves 901 on the outer wall of the camera 9, where heat exchange is performed, thereby playing a role in regulating the temperature of the camera 9;

[0071] A conical top 4 is installed on the top of the guide component 3, and its bottom diameter is larger than the diameter of the filter ring net 5 and is conical. When encountering rainy and snowy weather, the shape of the conical top 4 can conveniently guide the rain and snow to the outside of the shell 1, preventing rain and snow from entering the inside of the device, thereby protecting the internal guide component 3, filter ring net 5 and camera 9 and other components, ensuring that the entire device can work normally. At the same time, the setting of the conical top 4 and the shell 1 has a sunshade effect on the top of the camera 9 to prevent it from being directly exposed to the sun during work in summer.

[0072] As an implementation method, Figure 3 As shown, further:

[0073] The flow guide assembly 3 includes a rotating shaft 302 and a connecting plate 303. The connecting plate 303 is installed on the inner wall of the filter ring net 5. The rotating shaft 302 passes through the connecting plate 303 and is rotatably connected. The outer wall of the rotating shaft 302 is connected with a plurality of connecting pipes 301. One end of the connecting pipe 301 is connected with a flow guide bucket 304.

[0074] A fan blade 305 is installed at one end of the rotating shaft 302 and is located on the inner side of the shell 1 , and the bottom port of the rotating shaft 302 faces the top of the camera 9 .

[0075] In this embodiment, the purpose of the above arrangement is that the wind force generated by the vehicle flow acts on the concave inner wall of the diversion bucket 304, and the fan blade 305 is installed at one end of the rotating shaft 302 and is located on the inner side of the housing 1. The wind force drives the diversion bucket 304 to rotate, thereby driving the rotating shaft 302 to rotate;

[0076] The rotating shaft 302 passes through the connecting plate 303 and is rotatably connected thereto. The connecting plate 303 is mounted on the inner wall of the filtering annular net 5 to support the rotating shaft 302.

[0077] As the rotating shaft 302 rotates, a plurality of connecting pipes 301 connected on the outer wall thereof also rotate. A fan blade 305 is installed at one end of the rotating shaft 302. The fan blade 305 rotates to pour the airflow passing through the top of the filtering annular net 5 into the filter.

[0078] Under the action of the guide assembly 3, the airflow first passes through the filter ring net 5, and after the impurities are filtered out by the filter ring net 5, it enters the interior of the housing 1, flows from top to bottom along the housing 1, and finally flows to the inner side of the guide groove 901 on the outer wall of the camera 9 for heat exchange;

[0079] The bottom port of the rotating shaft 302 faces the top of the camera 9. This structural design is that when the wind acts on the concave inner wall of the guide bucket 304, a small amount of air flows through the connecting pipe 301. The port of the connecting pipe 301 is smaller, which avoids the weakening of the wind acting on the concave inner wall of the guide bucket 304. Then, the wind flows through the bottom port of the rotating shaft 302, which helps to more accurately guide the airflow to the guide groove 901 of the camera 9 to achieve more effective heat exchange.

[0080] As an implementation method, Figure 1 and Figure 3 As shown, further:

[0081] A brush plate 6 for cleaning the surface of the filtering annular net 5 is installed on the outer wall of the rotating shaft 302 .

[0082] In this embodiment, the purpose of the above arrangement is that when the rotating shaft 302 rotates, the brush plate 6 installed on its outer wall also rotates. Since the brush plate 6 is close to the surface of the filter ring net 5, when the brush plate 6 rotates, the surface of the filter ring net 5 is cleaned.

[0083] In the process of the airflow continuously passing through the filter ring net 5, dust, impurities, etc. may be filtered on the surface of the filter ring net 5. When the device is used for a long time, it will affect the filtering effect and the smoothness of the airflow. The rotation of the brush plate 6 can clean these impurities in time, maintain the good filtering performance of the filter ring net 5, and ensure that the airflow can continuously and smoothly pass through the filter ring net 5 into the interior of the shell 1.

[0088] The liquid storage box 7 is installed on the bottom outer wall of the housing 1 and is used to store cleaning liquid. When the surface of the camera 9 needs to be cleaned, the liquid storage box 7 provides cleaning liquid to the spray assembly 8;

[0089] The spray assembly 8 is installed on the bottom outer wall of the camera 9. After the liquid storage box 7 provides cleaning liquid to the spray assembly 8, the two arc-shaped brush plates 12 move downward, pushing the spray assembly 8 to run. The spray assembly 8 sprays the cleaning liquid onto the surface of the camera 9, and at the same time cooperates with the cleaning of the arc-shaped brush plates 12. Under the action of the hydraulic pressure, the cleaning liquid is sprayed out first, and the cleaning liquid is sprayed on the surface of the camera 9 first, followed by the arc-shaped brush plates 12 falling down to sweep away the dirt, thereby more effectively cleaning the surface of the camera 9.

[0092] In this embodiment, the purpose of the above arrangement is that when the rotating shaft 302 rotates, the second bevel gear 11 installed at the bottom of the rotating shaft 302 rotates accordingly;

[0093] The second bevel gear 11 is meshed with the two first bevel gears 1001 respectively. Since the two first bevel gears 1001 are symmetrically mounted on the outer wall of the connecting shaft 1004, when the second bevel gear 11 rotates, the two first bevel gears 1001 are driven to rotate.

[0094] Both ends of the connecting shaft 1004 are respectively connected to the inner wall of the housing 1 , so as to support the first bevel gear 1001 and maintain the stability of the first bevel gear 1001 during rotation.

[0099] The bottom of the push rod 1003 is rotatably connected to a connecting block, and the bottom of the push rod 1003 is connected to the arc-shaped brush plate 12 through the connecting block. When the top and bottom ends of the push rod 1003 move up and down, the two push rods 1003 respectively drive the arc-shaped brush plate 12 to slide up and down on the guide groove 901 on the outer wall of the camera 9, thereby realizing the cleaning function of the arc-shaped brush plate 12 on the outer wall of the camera 9.

[0100] As an implementation method, Figure 7 - Figure 8 As shown, further:

[0101] The spray assembly 8 includes a telescopic tube 801, a connecting ring 802, a spray pipe 803 and a one-way valve;

[0107] As an implementation method, Figure 7 As shown, further:

[0108] The plurality of nozzles 803 and the two arc-shaped brush plates 12 are in the same vertical direction.

[0109] In this embodiment, the purpose of the above arrangement is to coordinate the cleaning of the nozzle 803 with the arc-shaped brush plate 12 to maintain the consistency of cleaning of the camera 9.

[0110] As an implementation method, Figure 8 As shown, further:

[0111] The one-way valve includes a valve body, a valve core 804 and a spring 805. The valve body is installed on the bottom inner wall of the telescopic tube 801 and is connected. The bottom of the valve body is connected to the connecting ring 802. The spring 805 is installed on the bottom inner side of the valve body, and the valve core 804 is slidably connected to the top inner wall of the valve body.

[0112] In this embodiment, the purpose of the above arrangement is that when the telescopic tube 801 is squeezed by the arc-shaped brush plate 12, under the action of pressure, the cleaning liquid will push the valve core 804 to squeeze the spring 805, open the top port of the valve body, and the cleaning liquid flows through the valve body to the connecting ring 802.

[0113] When in use, the device is installed beside the road green belt. When the vehicle is driving fast, the vehicle flow will generate wind force, which serves as the starting power source of the airflow in the whole system. The guide component 3 is located on the inner side of the filter ring net 5. When the wind drives the guide component 3 to operate, it starts to guide the airflow. The airflow first passes through the filter ring net 5. The filter ring net 5 can perform preliminary filtering on the incoming airflow to prevent larger impurities from entering. The filtered airflow enters the interior of the housing 1. The top diameter of the housing 1 is larger than the bottom diameter to form a channel. The airflow flows from top to bottom along this channel. The airflow is more concentrated when it reaches the bottom of the housing 1 and the top of the camera 9.

[0114] Finally, the airflow flows to the inner side of the plurality of guide grooves 901 on the outer wall of the camera 9, where heat exchange is performed, thereby playing a role in regulating the temperature of the camera 9;

[0115] A conical top 4 is installed on the top of the guide component 3, and its bottom diameter is larger than the diameter of the filter ring net 5 and is conical. When encountering rainy and snowy weather, the shape of the conical top 4 can conveniently guide the rain and snow to the outside of the shell 1, preventing rain and snow from entering the inside of the device, thereby protecting the internal guide component 3, filter ring net 5 and camera 9 and other components, ensuring that the entire device can work normally. At the same time, the setting of the conical top 4 and the shell 1 has a sunshade effect on the top of the camera 9 to prevent it from being directly exposed to the sun during work in summer.
