Description

Technical Field

[0001] This utility model belongs to the field of air monitoring technology, and specifically relates to a mobile outdoor air pollution monitoring device. Background Technology

[0002] Air monitoring refers to the process of monitoring the air environment at fixed points, at fixed times, or at irregular points and times. Some environments, such as industrial areas and densely populated areas, require long-term air monitoring at relatively fixed times and locations, so fixed monitoring points are usually set up. In some places, the air environment is relatively stable and does not require long-term fixed monitoring, so mobile monitoring agencies can be used to monitor the environment to save resources and improve efficiency. Most existing monitoring equipment is equipped with a display screen to facilitate the timely display and publication of monitoring results.

[0003] A search revealed an existing air pollution monitoring device with technical announcement number CN220040385U. The advantages of this invention are: when birds perch on the crossbar, their droppings fall onto the bottom baffle, which shields the display, effectively preventing bird droppings from damaging the screen. The bird droppings on the top of the baffle can be scraped off by squeezing the connecting plate and sliding the scraper, facilitating cleaning. However, this process has significant drawbacks. First, the air monitoring device requires a certain height for monitoring. Therefore, the process of cleaning bird droppings on the baffle by squeezing the connecting plate and sliding the scraper requires lowering the device to a reachable position, thus reducing the monitoring height and indirectly interrupting the monitoring process. The process is also complex and reduces work efficiency.

[0004] Further prolonged exposure to outdoor conditions will cause dust and dirt to accumulate on the display screen, affecting visibility; additionally, monitoring operations need to be conducted in the field. Therefore, in severe weather such as strong winds, tree branches and other debris can be blown up and damage the display screen.

[0005] A search revealed a micro-station for monitoring environmental air pollution with the existing technology announcement number CN220104983U. This invention uses a drive motor installed inside a support rod to rotate a threaded rod. In conjunction with an abutment rod on one side of the upper end of the positioning shaft, as well as a locking rod and a limiting rod, it can rotate a cleaning plate on one side of the display screen to clean dust and impurities adhering to the display screen, preventing dust from obscuring the values ​​on the display screen. However, this invention also fails to solve the problem of effectively protecting the display screen during severe weather. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a mobile outdoor air pollution monitoring device. The cleaning mechanism can effectively clean the dust on the display screen. At the same time, by pulling the cleaning arm and connecting rod, a grid mesh can be formed to cover the surface of the display screen, thereby effectively protecting the display screen. It can also reduce the height of the display screen and the monitoring equipment body, which is conducive to the protection effect.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A mobile outdoor air pollution monitoring device includes a base housing, a battery, a fixed pole, a lifting pole, a monitoring device body, a baffle, a cleaning mechanism, a display screen, and a mounting frame. One end of the fixed pole is fixedly connected to the base housing, the battery is housed inside the base housing, and the lifting pole is inserted into the fixed pole. The monitoring device body is fixed to the top of the lifting pole, the baffle is fixed to the lifting pole and located below the monitoring device body, the mounting frame is located below the baffle and fixed to the lifting pole, and the display screen and cleaning mechanism are located on the mounting frame. The monitoring device body is electrically connected to the battery and the display screen.

[0009] The cleaning mechanism includes a fixed frame, cleaning arms, and a second pull rope. The fixed frame is bolted to the mounting frame, and the fixed frame has second through slots on its upper and lower sides. Several cleaning arms are provided, and each cleaning arm has a through shaft at both ends, which is located in the second through slot. The cleaning arms have a third through slot and a fourth through slot. A brush strip is also provided on one side of the cleaning arm for brushing the display screen. Adjacent cleaning arms are connected by a connecting rod, and the connecting rod has pins at both ends. One pin of the connecting rod is hinged to the third through slot of the cleaning arm, and the other pin is located in the fourth through slot. The connecting rod at the fourth through slot is lower than the other end of the connecting rod, forming an inclined angle. When the cleaning arm is pulled in the opposite direction, the pin at the connecting rod can slide downward in the fourth through slot to achieve the convergence of the cleaning arm and the connecting rod. The outermost connecting rod is hinged to the fixed frame. A limiting block is provided at one end of the third through slot and at one end of the fourth through slot to push and limit the connecting rod.

[0010] The second pull rope passes through the through shaft at the end of the sweeping arm. The second pull rope consists of a first segment and a second segment. The first segment passes through the through shaft at the top of the sweeping arm, and the second segment passes through the through shaft at the bottom of the sweeping arm. The first segment and the second segment are fixedly connected to the through shaft on the outermost sweeping arm. The fixing method here is to tighten the first segment and the second segment by screwing bolts on the through shaft.

[0011] The fixed frame is provided with a second hook plate, a third hook plate, and a fifth hook plate at both ends, and a fourth hook plate at the bottom of the fixed frame for guiding the direction of the second pull rope; the application of the fourth hook plate and the fifth hook plate can make the pulling force on both ends of the sweeping arm uniform when it slides.

[0012] Furthermore, to facilitate pulling and ensure even force distribution, the first and second line segments extending from the fifth hook plate are combined into a single pull rope below the fourth hook plate, making pulling even easier.

[0013] The baffle is provided with a scraper, and the baffle is provided with first through grooves on both sides. The bottom of the baffle is provided with a connecting arm, and the two ends of the connecting arm are located in the first through groove and are fixedly connected to the scraper. The two ends of the baffle are also provided with first hook plates, and the connecting arm is provided with a first pull rope fixedly connected to it. The two ends of the first pull rope pass through the first hook plate and are slidably connected to each other.

[0014] By alternately pulling both ends of the first rope, the scraper slides back and forth along the baffle surface to clean and sweep, avoiding unnecessary operation of controlling the lowering of the lifting rod.

[0015] The base box is equipped with rollers at the bottom and anchor rods on both sides; a push handle is provided on one side of the base box; the anchor rods are used to insert into the bottom surface for anchoring when the base box is parked; a counterweight is provided inside the base box for stability.

[0016] The top of the lifting rod is equipped with a crossbar for installing the monitoring equipment body, and the lifting rod is equipped with a support rod for tightening and guiding the first and second pull ropes; the lifting rod is equipped with teeth on one side.

[0017] The fixed rod has a central hole inside that matches the lifting rod; the top of the fixed rod has a lifting mechanism, which includes a fixed box, inside which is a worm gear and a rotating shaft. The two ends of the worm gear are rotatably connected to the fixed box, and the rotating shaft has a turbine and a gear. The gear meshes with teeth, and the turbine meshes with the worm gear; by rotating the worm gear, the turbine and the gear are driven to rotate, thereby driving the lifting rod to rise and fall; a frame is provided on one side of the fixed box for locking the first pull rope and the second pull rope to prevent the scraper and the sweeping arm from sliding freely after work is completed;

[0018] Furthermore, the lengths of the second and first pull ropes are sufficient to lock the frame when the lifting rod is raised to its highest point, and the sufficient length ensures that the scraper and sweeping arm can be operated smoothly without raising or lowering.

[0019] The advantages of this utility model compared with the prior art are as follows:

[0020] 1) This invention includes a baffle that can shield the display screen from falling debris, such as bird droppings from birds perched on the crossbar. The baffle is equipped with a scraper with a connecting arm. The connecting arm has a first pull rope that is fixedly connected to it. By alternately pulling the two ends of the first pull rope, the scraper can be moved back and forth along the surface of the baffle to clean the surface. The above operation can be carried out normally in air monitoring work, avoiding the complicated operation of lowering the lifting rod to an accessible height and then manually pushing the scraper. This solution is simple to operate and structure, saves time and effort, and can be performed at any time.

[0021] 2) This solution includes a cleaning mechanism mounted on a mounting frame that covers the display screen. When not in use, it can be retracted to one side of the mounting frame. When in use, pulling one end of the second pull rope causes the cleaning arm to slide along the second through slot, which in turn pulls adjacent cleaning arms to slide in conjunction with the connecting rod. This utilizes the brush strips to clean debris from the display screen. Pulling the other end of the second pull rope resets the cleaning arm, completing the retraction. The connecting rod then retracts into the third and fourth through slots, saving storage space. Furthermore, in inclement weather such as strong winds, pulling the cleaning arms and connecting rods in the cleaning mechanism can form a grid covering the display screen surface, reducing the chance of the display screen being covered or damaged by branches or other debris blown by the wind. The number of cleaning arms, the spacing between adjacent cleaning arms, and the number of connecting rods between adjacent cleaning arms can be set according to needs and manufacturing requirements to create a suitable protective grid. The above operation and control process can be performed at any time, avoiding the drawback of needing to lower the lifting rod to a reachable height for processing. During display screen protection, the height can be appropriately lowered to improve the protective effect.

[0022] Furthermore, the second pull rope's turning and stretching at the fifth hook plate ensures uniform tension on the first and second segments at both ends of the sweeping arm, promoting smooth sliding of the sweeping arm. Attached Figure Description
