This device includes a mounting base, a camera mounted on the bottom right side of the mounting base, a transparent cover covering the camera, and a rotating ring fixedly connected to the upper end of the transparent cover inside the mounting base. A worm gear is located on the left side of the rotating ring, and a cleaning rod is located on the left side of the transparent cover, with a dust collection component connected to the lower end of the cleaning rod. This invention uses a first motor to drive the transparent cover to rotate, which in turn contacts a brush for cleaning. A second motor drives a fan to rotate, drawing dust into a dust collection box through a suction hole. However, the above application has certain limitations in its use, specifically as follows:

[0004] The aforementioned application mainly uses mechanical bristles (brushes) and dust collection components (fan blades and dust collection box) for cleaning. Although this method can remove some dust, it requires frequent maintenance, which will increase maintenance costs to some extent. Since no dust prevention measures are mentioned, the camera cover is prone to rapid dust accumulation in dusty tunnel environments, affecting the monitoring effect. Therefore, the above document is mainly applicable to environments with less dust. For dusty tunnel environments, the cleaning effect may not be ideal. Utility Model Content

[0007] A mounting bracket is fixed to the lower surface of the mounting plate and near its left side, and the mounting bracket is provided with a cleaning mechanism for the maintenance of the camera body. The cleaning mechanism includes a dust removal component and a spray component.

[0008] The dust removal components include the following:

[0009] Miniature motor: It is fixed to the lower surface of the mounting bracket;

[0010] Connecting rod: It is rotatably connected to the upper surface of the mounting bracket via a bearing and fixed to one end of the micro motor output shaft;

[0012] Positioning rod: It is fixed to the top of the cleaning ring;

[0013] Miniature fan: It is fixed to the left side of the mounting bracket;

[0014] Air inlet box: It is fixed to the left side of the mounting bracket and located below the miniature fan;

[0015] Filter screen: It is installed on the air inlet box;

[0016] Ring tube: It is fixed to the lower surface of the mounting plate;

[0017] Internal mixing nozzles: There are no fewer than two of them, and they are all equidistantly connected and fixed to the lower surface of the annular tube.

[0018] Furthermore, a cleaning cotton is fixed inside the cleaning ring, and a ring-shaped positioning groove is provided on the lower surface of the mounting plate. The positioning rod is slidably connected inside the positioning groove and the two do not detach from each other.

[0019] Furthermore, the air inlet box is a hollow cuboid with partial gaps on its front, back, and left sides. The number of filters is three, and they are fixed to the gaps on the sides of the air inlet box.

[0020] Furthermore, the air inlet and air outlet of the micro fan are respectively connected and fixed with an air inlet pipe and an air outlet pipe, and the other end of the air inlet pipe is connected and fixed to the top surface of the air inlet box, and the other end of the air outlet is connected and fixed to the annular pipe.

[0023] Furthermore, the spray assembly also includes a control valve sleeved on the outside of the water outlet pipe, and the water storage tank is filled with cleaning fluid.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. This operation and maintenance management device for information collection cameras in highway tunnels integrates dust removal and spraying components to achieve automated cleaning and maintenance of the camera protective cover. A micro motor drives a cleaning ring to physically wipe the surface of the protective cover with cleaning cotton. At the same time, a micro water pump can spray the cleaning liquid in the water tank through atomizing nozzles to soften the dirt and improve the cleaning effect. This effectively solves the problem of blurred images caused by dust and dirt accumulation in tunnel cameras, ensuring the clarity and continuity of information collection.

[0026] 2. This operation and maintenance management device for information collection cameras in highway tunnels utilizes a miniature fan and filtration system to filter external air and form a clean airflow barrier around the protective cover through a ring pipe and nozzles. This airflow effectively blocks dust adhesion, significantly reduces the rate of contamination of the protective cover, and plays an active dust prevention role. In environments with severe dust, this airflow can also play a certain local dust reduction role, further optimizing the working environment of the camera, extending the cleaning cycle, and improving operation and maintenance efficiency.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-3 The operation and maintenance management device for a highway tunnel information collection camera in this embodiment includes a tunnel base 1, a mounting plate 2 fixed to the lower surface of the tunnel base 1 by bolts, a camera body 3 fixed to the lower surface of the mounting plate 2, and a protective cover 4 located outside the camera body 3 and providing dust protection fixed to the lower surface of the mounting plate 2.

[0033] Mounting bracket 5 is fixed on the lower surface of mounting plate 2 and near its left side, and a cleaning mechanism 6 for maintenance of camera body 3 is provided on mounting bracket 5. The cleaning mechanism 6 includes a dust removal component 61 and a spray component 62.

[0034] The dust removal component 61 includes the following components:

[0035] Miniature motor 6101: It is fixed to the lower surface of the mounting bracket 5;

[0036] Connecting rod 6102: It is rotatably connected to the upper surface of the mounting bracket 5 via a bearing and fixed to one end of the output shaft of the micro motor 6101;

[0037] Cleaning ring 6103: It is fixed to the top of the connecting rod 6102 and fits against the outer side of the protective cover 4;

[0038] Positioning rod 6104: It is fixed to the top of the cleaning ring 6103;

[0039] Miniature fan 6105: It is fixed to the left side of the mounting bracket 5;

[0040] Air inlet box 6106: It is fixed to the left side of the mounting bracket 5 and located below the micro fan 6105;

[0041] Filter 6107: It is installed on the air inlet box 6106;

[0042] Annular tube 6108: It is fixed to the lower surface of mounting plate 2;

[0043] Internal mixing nozzles 6109: There are no fewer than two of them, and they are equidistantly connected and fixed to the lower surface of the annular tube 6108.

[0044] It should be noted that the cleaning ring 6103 is driven to rotate by the micro motor 6101, and the atomized liquid sprayed by the micro fan 6105 and the internal mixing nozzle 6109 achieves efficient cleaning of the protective cover 4, effectively removing dust and dirt. At the same time, it has a dust reduction function, reducing the impact of dust on the camera body 3 and improving the monitoring quality. Its structure is simple, reducing the number of mechanical parts, reducing the risk of failure, and eliminating the need for an additional dust collection device, reducing maintenance workload and costs, and improving the ease of use and economy of the equipment.

[0045] The cleaning ring 6103 has a cleaning cotton fixed inside, and the mounting plate 2 has a ring-shaped positioning groove on its lower surface. The positioning rod 6104 is slidably connected inside the positioning groove and the two do not separate from each other.

[0046] It should be noted that the cleaning cotton fixed inside the cleaning ring 6103 enhances the cleaning effect on the protective cover 4, ensuring a cleaner surface. The sliding connection design between the ring-shaped positioning groove on the lower surface of the mounting plate 2 and the positioning rod 6104 ensures the stability of the cleaning ring 6103 during rotation, preventing it from shifting during cleaning, thereby improving the uniformity and reliability of cleaning, and further enhancing the cleaning efficiency and maintenance performance of the entire device.

[0047] The air inlet box 6106 is a hollow cuboid with partial gaps on its front, back, and left sides. There are three filters 6107, which are fixed to the gaps on the sides of the air inlet box 6106.

[0048] It should be noted that the air inlet box 6106 adopts an internally hollow cuboid structure, with its front, rear, and left sides missing. This design helps to increase the air intake area and improve air circulation efficiency. At the same time, three filters 6107 are fixed to the missing parts on the side of the air inlet box 6106, which can effectively filter the incoming air and prevent dust and impurities from entering the subsequent airflow system, thereby improving the cleaning effect and extending the service life of the equipment.

[0049] The micro fan 6105 has an air inlet pipe and an air outlet pipe respectively connected and fixed to the air inlet end and the air outlet end. The other end of the air inlet pipe is connected and fixed to the top surface of the air inlet box 6106, and the other end of the air outlet end is connected and fixed to the annular pipe 6108.

[0050] It should be noted that the air inlet of the micro fan 6105 is connected to the top surface of the air inlet box 6106 through the air inlet pipe, and the air outlet is connected to the annular pipe 6108 through the air outlet pipe, forming a complete airflow circulation system. This design ensures a stable supply of airflow. The micro fan 6105 draws the filtered air out of the air inlet box 6106 and then sprays it out through the annular pipe 6108 and the internal mixing nozzle 6109 to form atomized liquid, thereby achieving efficient cleaning and dust reduction of the protective cover 4.

[0051] The mounting bracket 5 includes a horizontal plate and a vertical plate, with the vertical plate being fixed vertically to the left side of the upper surface of the horizontal plate, and the cross-sectional shape of the mounting bracket 5 is L-shaped.

[0052] The spray assembly 62 includes a water storage tank 6201 fixed to the lower surface of the horizontal plate, a micro water pump 6202 fixed to the upper surface of the horizontal plate, a water inlet end of the micro water pump 6202 connected to a water suction pipe 6203, one end of the water suction pipe 6203 penetrating and extending into the interior of the water storage tank 6201, and a water outlet end of the micro water pump 6202 connected to a water outlet pipe 6204, one end of the water outlet pipe 6204 being connected to and fixed to an annular pipe 6108.

[0053] It should be noted that the spray assembly 62 includes a water storage tank 6201, which is fixed to the lower surface of the horizontal plate of the mounting bracket 5 for storing cleaning fluid. A micro water pump 6202 is fixed to the upper surface of the horizontal plate and draws cleaning fluid from the water storage tank 6201 through the water suction pipe 6203, and delivers it to the annular pipe 6108 through the water outlet pipe 6204. Finally, it is sprayed out through the internal mixing nozzle 6109 to achieve spray cleaning of the protective cover 4. This design not only improves the cleaning efficiency, but also reduces dust near the camera body 3, reduces the impact of dust on the camera, and improves the monitoring quality.

[0054] The spray assembly 62 also includes a control valve sleeved on the outside of the water outlet pipe 6204, and the water storage tank 6201 is filled with cleaning fluid.

[0055] It should be noted that the spray assembly 62 also includes a control valve, which is sleeved on the outside of the outlet pipe 6204 to control the flow rate of the cleaning fluid and the spraying state. The water storage tank 6201 is filled with cleaning fluid, which can effectively remove dust and dirt from the protective cover 4. By adjusting the control valve, the micro water pump 6202 draws the cleaning fluid from the water storage tank 6201, delivers it through the outlet pipe 6204 to the annular pipe 6108, and sprays it out through the internal mixing nozzle 6109 to form an atomized liquid, thereby achieving efficient cleaning of the protective cover 4. This design not only improves the cleaning effect, but also allows for adjustment of the spray intensity as needed, saving the use of cleaning fluid and further enhancing the economy and practicality of the equipment.

[0056] In this application, the internal mixing nozzle 6109 is a prior art technology. Its design allows the airflow to form a protective layer when no liquid is introduced, effectively preventing dust from adhering to the protective cover 4. When cleaning is required, the internal mixing nozzle 6109 can mix the airflow with the liquid to produce atomized liquid. This atomized liquid can not only reduce dust and reduce the impact of dust on the camera body 3, but also be evenly sprayed onto the upper side of the protective cover 4, making it easy for the cleaning ring 6103 to wipe and clean. This multi-functional design improves cleaning efficiency, reduces maintenance workload, and enhances the reliability and economy of the equipment.

[0057] The working principle of the above embodiment is as follows: The micro motor 6101 drives the connecting rod 6102, and the cleaning cotton on the cleaning ring 6103 contacts the protective cover 4 for dust removal. This is a conventional solution in the prior art. In order to keep the protective cover 4 free from dust for a long time, this application uses the micro fan 6105 to filter the outside air through the filter screen 6107 before it reaches the annular pipe 6108. The use of three filters 6107 avoids the need for frequent cleaning, reducing the maintenance cycle. Multiple internal mixing nozzles 6109 on the upper side of the annular tube 6108 spray out to form an airflow to protect the protective cover 4 from dust. This can prevent a large amount of dust from adhering to the upper side of the protective cover 4. After a long period of dust accumulation, the micro water pump 6202, after the control valve is opened, allows the cleaning liquid to reach the interior of the internal mixing nozzles 6109 and form an atomized liquid sprayed onto the upper side of the protective cover 4 to facilitate the cleaning work of the cleaning ring 6103. At the same time, in environments with poor dust quality, it can also reduce dust near the camera body 3 to prevent excessive dust from adhering to the protective cover 4.
