Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and more specifically, to an environmental monitoring device capable of continuous monitoring. Background Technology

[0002] Atmospheric environmental monitoring is an important means of assessing ambient air quality through qualitative and quantitative analysis of suspended particulate matter (such as PM2.5 and PM10) and gaseous pollutants in the air. In existing monitoring equipment, the sampling head, as the inlet for collecting gas samples, is usually equipped with a filter. This filter is mainly used to intercept large particulate impurities, dust, and fibrous debris in the air, preventing these foreign objects from entering the downstream precision detection gas path, thereby protecting the sensors and analytical instruments, and ensuring the accuracy of monitoring data and the long-term stable operation of the equipment.

[0003] For example, the specification of the "A Continuously Detectable Environmental Monitoring Device" disclosed in Chinese Utility Model Patent (Publication No.: CN220829239U) states that: by adjusting the height of the environmental monitoring device, it is convenient to detect environmental data at different heights. The user rotates a disc, which drives a metal worm gear to rotate, which in turn drives a metal worm wheel to rotate, which in turn drives a screw to rotate, which in turn moves a plastic lifting rod upwards, which in turn moves the environmental monitoring device. The movement of the environmental monitoring device allows for height adjustment, enabling the detection of the environment at different heights, thus achieving the effect of continuous detection. The existing technology has significant shortcomings in practical applications. The sampling pipeline on the environmental monitoring equipment lacks an automatic cleaning function, requiring manual periodic removal of the sampling head from the top of the station building and disassembly of the outer casing to remove the filter for cleaning or replacement. This maintenance process is cumbersome, labor-intensive, and frequent disassembly and assembly can easily lead to wear and aging of the sampling head's sealing ring, stripping of the thread structure, and subsequent secondary failures such as decreased gas circuit sealing and even leakage. This severely weakens the long-term reliability and data continuity of the equipment, and cannot meet the automated operation and maintenance requirements of unattended scenarios.

[0004] Therefore, we have made improvements to this and proposed an environmental monitoring device that can continuously detect environmental data. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a continuously detectable environmental monitoring device, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A continuously detectable environmental monitoring device includes a base, a pole fixedly installed on the top of the base, a monitor body fixedly installed on the top of the pole, a plurality of fixed rods fixedly installed on the top of the pole, a baffle plate fixedly installed on the top of the fixed rods, a sampling tube provided at the front end of the monitor body, and a filter screen fixedly installed at the front opening of the sampling tube. A liquid storage tank is fixedly installed on the outer wall of the upright, and a backwash pipe is fixedly installed on the top of the liquid storage tank. One end of the backwash pipe is fixedly connected to the sampling tube. A cleaning component is provided on the front side of the bottom of the shield, and a pump body is provided on the backwash pipe.

[0007] As a preferred technical solution of this application, the cleaning component includes a track fixedly installed on the front side of the bottom of the shield, a slider slidably installed on the track, a cleaning scraper fixedly installed at the bottom of the slider, the cleaning scraper slidingly contacting the front end of the sampling tube, and a driving mechanism provided on the front side of the bottom of the shield.

[0008] As a preferred technical solution of this application, the driving mechanism includes an electric telescopic rod fixedly installed on the front side of the bottom of the baffle plate, and the driving end of the electric telescopic rod is fixedly connected to the extension block on the back of the slider.

[0009] As a preferred technical solution of this application, the cleaning scraper is made of rubber.

[0010] As a preferred technical solution of this application, an electric valve is provided on the upper side of the sampling tube at the rear of the connection between the backwash pipe and the sampling tube.

[0011] As a preferred technical solution of this application, an addition pipe is fixedly installed on the upper side of one side of the liquid storage tank, and a discharge pipe is fixedly installed on the lower side of one side of the liquid storage tank.

[0012] As a preferred technical solution of this application, the front of the liquid storage tank is provided with a visualization window.

[0013] As a preferred technical solution of this application, a flow sensor is provided inside the sampling tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By installing a filter screen at the front end of the sampling tube to filter the air and installing a liquid storage tank on the outer wall of the pole, the cleaning liquid is pumped into the sampling tube for backwashing through the backwash pipe and pump body. At the same time, the electric valve cuts off the air passage between the sampling tube and the main body of the monitor during cleaning. This effectively solves the technical problems of cumbersome operation, high labor intensity, and secondary failures such as wear of sealing rings and stripping of threads caused by frequent disassembly and assembly, which are caused by manual disassembly and cleaning in the existing technology. It realizes the function of cleaning the filter screen online without disassembly, which significantly reduces maintenance costs and equipment failure rate.

[0015] 2. By setting a cleaning component at the bottom front of the baffle plate, the track, slider and cleaning scraper in the cleaning component cooperate with each other. Driven by the drive mechanism, the cleaning scraper moves back and forth along the track to clean the outer surface of the filter screen at the front end of the sampling tube. The cleaning scraper is made of rubber, which ensures cleaning power and avoids scratching the filter screen. The mechanical scraping of the cleaning scraper and the backwash liquid flow work together to effectively remove stubborn particles attached to the surface of the filter screen, greatly improving the thoroughness and effectiveness of cleaning and ensuring the long-term smooth operation of the filter screen.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example 1 Please refer to Figures 1-5 An environmental monitoring device capable of continuous detection includes a base 1, a pole 2 fixedly mounted on the top of the base 1, a monitor body 3 fixedly mounted on the top of the pole 2, several fixing rods 17 fixedly mounted on the top of the pole 2, a baffle plate 4 fixedly mounted on the top of the fixing rods 17, a sampling tube 9 provided at the front end of the monitor body 3, and a filter screen fixedly mounted at the front opening of the sampling tube 9; a liquid storage tank 5 fixedly mounted on the outer wall of the pole 2, a backwash pipe 6 fixedly mounted on the top of the liquid storage tank 5, one end of the backwash pipe 6 fixedly connected to the sampling tube 9, a cleaning component 11 provided on the front side of the bottom of the baffle plate 4, and a pump body 8 provided on the backwash pipe 6.

[0023] The main body of the monitor 3 and the shielding plate 4 are stably erected at a high place by the base 1, the upright 2 and the fixed rod 17, ensuring that the front opening of the sampling tube 9 is in full contact with the outside air, thereby improving the representativeness of the sampling. The setting of the liquid storage tank 5, the backwash pipe 6 and the pump body 8 forms the backwash liquid path, providing a structural basis for subsequent online cleaning.

[0024] Furthermore, an electric valve 10 is installed on the upper side of the sampling tube 9 at the rear of the connection between the backwash pipe 6 and the sampling tube 9.

[0025] By installing an electric valve 10 on the sampling tube 9 at the rear of the connection with the backwash pipe 6, the valve can be closed during backwashing cleaning to cut off the air path between the sampling tube 9 and the monitor body 3, effectively preventing cleaning waste liquid and impurities from being flushed into the monitoring equipment and avoiding secondary pollution and equipment damage.

[0026] Furthermore, an addition pipe 7 is fixedly installed on the upper side of one side of the liquid storage tank 5, and a discharge pipe 12 is fixedly installed on the lower side of one side of the liquid storage tank 5.

[0027] By installing an addition pipe 7 above and a discharge pipe 12 below the liquid storage tank 5, cleaning liquid can be easily added to the liquid storage tank 5, and waste liquid and impurities that have settled at the bottom of the tank can be discharged regularly, reducing maintenance difficulty and extending the service life of the cleaning system.

[0028] Furthermore, a viewing window is provided on the front of the liquid storage tank 5.

[0029] By setting a visualization window on the front of the liquid storage tank 5, maintenance personnel can intuitively observe the liquid level and cleanliness inside the liquid storage tank 5 at any time, which facilitates timely replenishment or replacement of liquid and avoids failure of the cleaning function due to insufficient cleaning fluid.

[0030] Furthermore, a flow sensor is installed inside the sampling tube 9.

[0031] By installing a flow sensor inside the sampling tube 9, the changes in the sampling airflow can be monitored in real time. When the flow drops to a preset threshold, a cleaning command is automatically triggered, enabling intelligent judgment of the cleaning timing and avoiding the impact of filter clogging on the accuracy of the sampling data.

[0032] Example 2 The environmental monitoring device for continuous detection provided in Embodiment 1 is further optimized. Specifically, the cleaning component 11 includes a track 13 fixedly installed on the front side of the bottom of the shield 4, a slider 14 slidably installed on the track 13, a cleaning scraper 15 fixedly installed on the bottom of the slider 14, the cleaning scraper 15 slidingly contacting the front end of the sampling tube 9, and a driving mechanism provided on the front side of the bottom of the shield 4.

[0033] Through the cooperative structure of track 13, slider 14 and cleaning scraper 15, the cleaning scraper 15 can reciprocate along track 13 under the drive mechanism to scrape and clean the filter screen at the front end of sampling tube 9. It works synergistically with the backwash liquid flow to effectively remove stubborn particles attached to the surface of the filter screen and significantly improve the cleaning effect.

[0034] Furthermore, the drive mechanism includes an electric telescopic rod 16 fixedly installed on the front side of the bottom of the baffle plate 4, and the drive end of the electric telescopic rod 16 is fixedly connected to the extension block on the back of the slider 14.

[0035] By using an electric telescopic rod 16 as the driving mechanism, its driving end is fixedly connected to the slider 14 through an extension block, which can realize the reciprocating linear motion of the cleaning scraper 15. The structure is simple, the control is convenient, and the telescopic action is stable and reliable, which helps to ensure the stability of the cleaning process.

[0036] Furthermore, the cleaning scraper 15 is made of rubber.

[0037] By making the cleaning scraper 15 a rubber material, it is possible to ensure that the scraper has sufficient cleaning force when it comes into contact with the filter screen surface, while avoiding hard scratches on the filter screen. At the same time, the rubber material has a certain degree of elastic deformation ability, which can better adapt to the micro-undulations of the filter screen surface, improve the cleaning fit and cleaning effect.

[0038] The usage process of the environmental monitoring device capable of continuous detection provided by this utility model is as follows: During normal atmospheric environmental monitoring, the main body 3 of the monitor collects outside air through the sampling tube 9 at its front end and delivers the sampled gas to the sensors and analysis unit inside the main body 3 for detection, thereby obtaining environmental quality data. Outside air enters through the opening at the front end of the sampling tube 9. A filter screen fixedly installed at the front end of the sampling tube 9 intercepts and filters large particulate impurities, dust, and fibrous debris in the air, preventing foreign objects from entering the monitor body 3 and thus protecting the downstream precision detection gas path and sensors. At this stage, the electric valve 10 located on the backwash pipe 6 behind the connection between the sampling tube 9 and the backwash pipe 6 is in the open state to ensure unobstructed sampling gas path; simultaneously, the pump 8 located on the backwash pipe 6 is in the closed state and does not perform backwashing operation. Furthermore, a flow sensor inside the sampling tube 9 monitors the sampling flow rate in real time. When the flow rate drops to a preset threshold, it is determined that the filter screen blockage has affected normal sampling, thus triggering a cleaning command and preparing to enter the cleaning stage.

[0039] Upon triggering the cleaning command, the system first closes the electric valve 10, cutting off the air connection between the sampling tube 9 and the monitor body 3 to prevent impurities from being flushed into the monitoring device during the cleaning process. Then, the pump 8 is activated, pumping the cleaning liquid, such as water or a special cleaning agent, stored in the storage tank 5 into the sampling tube 9 through the backwash pipe 6. The cleaning liquid flows from back to front within the sampling tube 9, backwashing the clogged filter screen and causing particles adhering to the filter screen surface to detach under the impact of the liquid flow. Simultaneously, the cleaning component 11, located at the bottom front of the baffle plate 4, is activated. Specifically, the electric telescopic rod 16 in the cleaning component 11 acts as a drive mechanism, extending and retracting. Its drive end, via an extension block, drives the slider 14 to reciprocate along the track 13. The cleaning scraper 15, fixedly installed at the bottom of the slider 14, moves along with the slider 14, sliding against the front end of the sampling tube 9 to reciprocate and scrape the outer surface of the filter screen. Combined with the backwash liquid flow, this thoroughly removes stubborn deposits from the filter screen surface. During the cleaning process, the impurities and waste liquid washed off are discharged from the opening at the front end of the sampling tube 9. After the set cleaning time is completed, the pump body 8 is turned off and the electric telescopic rod 16 stops moving. Then, the electric valve 10 is opened to restore the monitor body 3 to normal sampling operation. In addition, the liquid storage tank 5 can be replenished with cleaning liquid through the addition tube 7 located on its top, and the liquid level in the tank can be observed at any time through the visualization window on the front of the liquid storage tank 5.
