Description

Technical Field

[0001] This utility model relates to the field of pollution detection equipment technology, specifically to an environmental dust pollution detection device. Background Technology

[0002] Environmental monitoring involves detecting the content and emissions of various substances that affect humans and the environment to track changes in environmental quality, determine environmental quality levels, and provide a foundation and guarantee for environmental management and pollution control. Simply put, understanding the environmental level and conducting environmental monitoring are prerequisites for all environmental work. Environmental monitoring typically includes processes such as background investigation, scheme determination, optimized site selection, on-site sampling, sample transportation, experimental analysis, data collection, and data synthesis. In general, it is a process of obtaining information through planning, sampling, analysis, and synthesis.

[0003] For example, the application document with application number 202121007737.8 discloses an environmental dust pollution detection device with an adsorption structure. This utility model is equipped with a dust adsorption structure, which can further detect the dust pollution index in the environment over a wide range and effectively improve the accuracy of the detection results. However, this environmental dust pollution detection device uses a suction pump device when performing air adsorption. This device is an electrical device that requires power to operate, which will increase the manufacturing cost of the entire detection device and is not conducive to use and maintenance, thus reducing its practicality. Furthermore, the dust adsorbed by the suction pump and filter screen is detected inside the chamber, which is not convenient for discharge after the detection is completed, thus affecting the next detection.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose an environmental dust pollution detection device. Utility Model Content

[0005] The purpose of this invention is to provide an environmental dust pollution detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmental dust pollution detection device, comprising a detection body, a sampling cylinder fixedly installed on the upper surface of the detection body, four one-way air inlet valves evenly distributed around the lower surface of the sampling cylinder, a piston plate slidably disposed inside the sampling cylinder, a one-way air outlet valve penetrating through the upper right side of the piston plate, a connecting plug threaded to the upper end of the one-way air outlet valve, and a support mesh fixedly disposed on both the upper and lower ends of the inner surface of the connecting plug.

[0007] Preferably, the bottom of the sampling tube is connected to the detection head of the detection machine, and the middle of the support mesh is filled with activated carbon.

[0008] Preferably, a connecting rod is fixedly installed at the center of the upper part of the piston plate surface, and a movable shell is fixedly provided at the upper end of the connecting rod.

[0009] Preferably, the diameter of the movable shell is the same as the diameter of the detection body, and the height of the movable shell is slightly higher than that of the sampling cylinder.

[0010] Preferably, two damping sliders are fixedly provided on the lower front and rear sides of the inner surface of the movable shell. The corresponding positions of the damping sliders are provided with damping grooves on the surface of the sampling cylinder, and the damping sliders are slidably disposed inside the damping grooves.

[0011] Preferably, an iron sheet is fixedly provided at the bottom edge of the movable shell, and a magnetic suction sheet is fixedly installed below the iron sheet at the upper edge of the surface of the detection body.

[0012] Preferably, a display screen is fixedly installed on the front center of the outer surface of the detection body, and the display screen is connected to the internal electrical components of the detection body via a transmission line.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of a sampling cylinder, a one-way air inlet valve, a piston plate, a one-way air outlet valve, a connecting plug, and a support mesh, allows air to be drawn into the sampling cylinder through the one-way air inlet valve when the piston plate moves upward. This increases the air extraction range, enabling a wider range of dust pollution index detection and effectively improving the accuracy of the test results. When the piston plate moves downward, it compresses the air inside the sampling cylinder and discharges it through the one-way air outlet valve, thus emptying the sampling cylinder in preparation for the next test. The discharged air passes through the connecting plug, and the activated carbon filled inside the support mesh adsorbs particulate matter in the air, thereby purifying and filtering the discharged air and preventing environmental pollution.

[0015] 2. This utility model, through the arrangement of a connecting rod, a movable shell, a damping slider, a damping groove, an iron sheet, and a magnetic absorbing plate, allows manual adjustment of the movable shell, connected by the connecting rod, to move the piston plate up and down. When the movable shell moves upward to open, the piston plate moves upward for air intake detection; when the movable shell moves downward, the piston plate moves downward for exhaust and storage. During the movement of the movable shell, the damping slider slides along the damping groove, limiting the maximum upward movement of the movable shell and making its movement more stable. When the movable shell moves downward to store, the magnetic absorbing plate attracts the iron sheet, ensuring a tight and secure seal between the movable shell and the detection body, preventing the movable shell from shaking, stretching, or opening. This also reduces the overall size of the equipment, making it more portable and easier to use. Attached Figure Description

[0022] 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.

[0023] like Figures 1-5 As shown, an environmental dust pollution detection device includes a detection body 1. A sampling cylinder 2 is fixedly installed on the upper surface of the detection body 1. Four one-way air inlet valve ports 3 are evenly distributed around the lower surface of the sampling cylinder 2. A piston plate 4 is slidably installed inside the sampling cylinder 2. A one-way air outlet valve port 5 is provided through the upper right side of the piston plate 4. A connecting plug 6 is threaded to the upper end of the one-way air outlet valve port 5. Support nets 7 are fixedly installed on the upper and lower ends of the inner surface of the connecting plug 6.

[0024] By adopting the above technical solution, when the piston plate 4 moves upward, the gas cannot enter through the one-way outlet valve 5, but can only enter through the one-way inlet valve 3. Suction allows the equipment to monitor the dust pollution index of a wider range of environments. Conversely, when the piston plate 4 moves downward, the gas can only be discharged through the one-way outlet valve 5 and cannot be discharged through the one-way inlet valve 3. The air discharged through the one-way outlet valve 5 will enter the interior of the connecting plug 6. The threaded connecting plug 6 can be easily replaced with the one-way outlet valve 5.

[0025] Furthermore, the bottom of the sampling tube 2 is connected to the detection head of the detection body 1, and the middle of the support net 7 is filled with activated carbon.

[0026] By adopting the above technical solution, the gas drawn in from the sampling cylinder 2 can come into contact with the detection head of the detection body 1, thereby performing pollution index detection; the exhaust gas will pass through the activated carbon filter inside the connecting plug 6 to adsorb and remove particulate impurities, thereby improving the cleanliness of the exhaust air.

[0027] Furthermore, a connecting rod 8 is fixedly installed at the upper center of the piston plate 4, and a movable shell 9 is fixedly installed at the upper end of the connecting rod 8.

[0028] By adopting the above technical solution, the piston plate 4 can be moved up and down by adjusting the movable shell 9 and connecting it with the connecting rod 8. When the movable shell 9 moves up and opens, the piston plate 4 moves up to perform air intake detection. When the movable shell 9 moves down, the piston plate 4 moves down to perform exhaust collection.

[0029] Furthermore, the diameter of the movable shell 9 is the same as the diameter of the detection body 1, and the height of the movable shell 9 is slightly higher than that of the sampling cylinder 2.

[0030] By adopting the above technical solution, the edge of the movable shell 9 can be perfectly matched and connected with the detection body 1 to form a complete whole.

[0031] Furthermore, two damping sliders 10 are fixedly installed on the lower front and rear sides of the inner surface of the movable shell 9. The corresponding positions of the damping sliders 10 are provided with damping grooves 11 on the surface of the sampling cylinder 2, and the damping sliders 10 are slidably disposed inside the damping grooves 11.

[0032] By adopting the above technical solution, the damping slider 10 will slide along the damping groove 11, limiting the maximum upward movement of the movable shell 9, avoiding excessive upward movement and falling off, and making the movement of the movable shell 9 more stable.

[0033] Furthermore, an iron sheet 12 is fixedly installed at the bottom edge of the movable shell 9, and a magnetic suction sheet 13 is fixedly installed below the iron sheet 12 on the upper edge of the surface of the detection body 1.

[0034] By adopting the above technical solution, when the movable shell 9 is lowered and stored, the magnetic plate 13 will attract the iron plate 12, so that the movable shell 9 can be tightly and firmly attached to the detection body 1, preventing the movable shell 9 from shaking, stretching and opening. At the same time, it also reduces the overall size of the equipment, making it more convenient to carry and use.

[0035] Furthermore, a display screen 14 is fixedly installed on the front center of the outer surface of the testing body 1, and the display screen 14 is connected to the internal electrical components of the testing body 1 via a transmission line.

[0036] By adopting the above technical solution, the detected pollution index will be presented intuitively on the display screen 14, which is convenient for manual observation and judgment.

[0037] Working Principle: When using this environmental dust pollution detection equipment, firstly, when it is necessary to detect the pollution index of environmental dust, manually pull the movable shell 9 upwards to expand the entire device. The movable shell 9 moves upwards and opens, which in turn pulls the piston plate 4 upwards via the connecting rod 8. This creates a principle similar to that of a syringe, drawing air in through the one-way air inlet 3, drawing outside air into the sampling cylinder 2. This suction increases the air extraction range. Then, the air inside the sampling cylinder 2 comes into contact with the detection head of the detection body 1, thereby detecting the dust pollution index in the air. The detection result is displayed on the screen 14. After the detection is completed, the movable shell 9 moves downwards, and the piston plate 4 moves downwards. At this time, the piston plate 4 compresses the air in the sampling cylinder 2. Due to the single... Since exhaust cannot be completed through the air inlet valve 3, the compressed air can only be discharged through the one-way exhaust valve 5, thus emptying the air inside the sampling cylinder 2 in preparation for the next test. The discharged air will pass through the connecting plug 6, and the activated carbon filled inside the support mesh 7 will adsorb particulate matter in the air, thereby purifying and filtering the discharged air. When the movable shell 9 moves to the bottom, the piston plate 4 also moves to the bottom of the sampling cylinder 2, completely expelling the air. At the same time, the magnetic suction plate 13 will attract the iron plate 12, so that the movable shell 9 can be tightly and firmly sealed with the detection body 1, preventing the movable shell 9 from shaking, stretching and opening. At the same time, it also reduces the overall size of the equipment, making it more convenient to carry and use. This is the working principle of this environmental dust pollution detection equipment.
