Description

Technical Field

[0001] The utility model relates to an air pollution dynamic detection device, belonging to the technical field of environmental detection. Background Art

[0002] After long-term use, the existing air quality detection instruments often accumulate a lot of dust on the filter screen on the air inlet side, which seriously affects the air circulation and the accuracy of the test results. To solve this problem, the traditional method is to remove the filter screen, clean it, and then reinstall it. Unfortunately, since many filters are fixed by bolts, this disassembly and assembly process is often quite cumbersome and inconvenient.

[0003] In order to improve this situation, an atmospheric pollution dynamic detection device is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an atmospheric pollution dynamic detection device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a dynamic detection device for air pollution, comprising:

[0006] The detection box includes a box body, a ventilation pipe is sleeved inside the box body, and both ends of the ventilation pipe are open. A fan and a detector for detecting air pollution are arranged inside the ventilation pipe. When the fan is started, external gas can be sucked into the ventilation pipe from the air inlet. After the sucked gas contacts the detector, the detector performs dynamic detection of gas pollution. The detected gas will be discharged from the air outlet of the ventilation pipe, realizing a dynamic cycle of gas detection.

[0007] The filter assembly is installed at one end of the ventilation pipe where the air inlet is set, wherein the filter assembly includes a slide plate and a filter screen, the slide plate is set at the center position of the filter screen, and an end plate 1 is set at one end of the ventilation pipe where the air inlet is set, and the slide plate is installed on the end plate 1.

[0008] Preferably, the upper and lower sides of the slide plate are relatively bent into U-shaped clamping edges, and the slide plate is slidably buckled on the end plate one through the U-shaped clamping edge, and the end of the box body close to the air inlet of the ventilation pipe is fixedly connected to the end plate two. When the slide plate is installed on the end plate one and the ventilation pipe is slid into the interior of the box body, the end plate two and the edge of the slide plate are clamped together.

[0009] Preferably, a plurality of limit columns are evenly distributed on both sides of the slide plate, and a plurality of limit grooves cooperating with the limit columns are opened on the second end plate. When the first end plate and the second end plate clamp the slide plate, the limit columns are inserted into the corresponding limit grooves to prevent the slide plate from moving.

[0010] Preferably, a mounting frame 2 is fixedly installed in the ventilation duct and near the air outlet of the ventilation duct, and two dampers are symmetrically fixedly connected to the mounting frame 2. When the fan is running, the air in the ventilation duct flows, and the flowing air will push open the two dampers. In this way, the two dampers are opened to facilitate the circulation of air in the ventilation duct. When the fan stops, the two dampers are closed, which can prevent impurities from entering from the air outlet of the ventilation duct to ensure the cleanliness of the ventilation duct.

[0011] Preferably, a blocking rod for limiting the opening and closing angles of the two dampers is connected to the second mounting frame, and a cushion block is fixedly connected to the bottom of the box body, and the cushion block gradually becomes thicker from front to back.

[0012] Preferably, a mounting frame 1 is provided inside the ventilation duct, and the fan and the detector are installed on the mounting frame 1.

[0013] Preferably, side grooves are provided on both sides of the ventilation pipe, and the interiors of the two side grooves are rotatably connected to rotating rods through springs. Blocks are provided on the side walls of the rotating rods, and a slot is provided on the inner wall of the box.

[0014] Preferably, a controller for controlling the operation of the fan and the detector and a battery module for providing electrical energy are installed in the box, and the battery module is electrically connected to the fan, the detector and the controller.

[0015] Compared with existing technologies:

[0016] 1. The utility model is started by a fan, and external gas can be sucked in from the air inlet of the ventilation duct. After the sucked gas contacts the detector, the detector performs dynamic detection of gas pollution. The detected gas will be discharged from the air outlet of the ventilation duct, realizing the cyclic operation of gas detection.

[0017] 2. After the utility model is installed on the end plate through the slide plate, the filter screen faces the air inlet of the ventilation duct, and the filter screen can cover the air inlet of the ventilation duct. When the external air enters the ventilation duct from the air inlet of the ventilation duct, the gas is first filtered by the filter screen, so that the filter screen can intercept impurities in the gas and ensure the cleanliness of the ventilation duct.

DETAILED DESCRIPTION

[0027] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0028] Example 1

[0029] like Figure 1-Figure 5 As shown, in this embodiment, a dynamic detection device for atmospheric pollution is provided, comprising:

[0030] The detection box 1 includes a box body 101, and a ventilation pipe 102 is sleeved inside the box body 101. Both ends of the ventilation pipe 102 are open, wherein a fan 2 and a detector 3 for detecting air pollution are arranged inside the ventilation pipe 102. When the fan 2 is started, external gas can be sucked into the ventilation pipe 102 from the air inlet of the ventilation pipe 102. After the sucked gas contacts the detector 3, the detector 3 performs dynamic detection of gas pollution, and the detected gas is discharged from the air outlet of the ventilation pipe 102, thereby realizing a dynamic cycle of gas detection;

[0031] The filter assembly 5 is installed at one end of the ventilation pipe 102 where the air inlet is set, wherein the filter assembly 5 includes a slide plate 501 and a filter screen 502, the slide plate 501 is set at the center of the filter screen 502, and an end plate 6 is set at one end of the ventilation pipe 102 where the air inlet is set, and the slide plate 501 is installed on the end plate 6, such as Figure 2As shown, when the slide plate 501 is installed on the end plate 6, the filter 502 is opposite to the air inlet of the ventilation duct 102, and the filter 502 can cover the air inlet of the ventilation duct 102. When external air enters the ventilation duct 102 from the air inlet of the ventilation duct 102, the gas is first filtered by the filter 502, so that the filter 502 can intercept impurities in the gas, thereby ensuring the cleanliness of the ventilation duct 102.

[0032] Example 2

[0033] like Figure 3 As shown, on the basis of Example 1, in order to enable the slide plate 501 to be quickly installed on the end plate 106, the upper and lower sides of the slide plate 501 are relatively bent into U-shaped clamping edges, and the slide plate 501 is slidably buckled on the end plate 106 through the U-shaped clamping edge, and the end of the box body 101 close to the air inlet of the ventilation pipe 102 is fixedly connected with the end plate 27. When the slide plate 501 is installed on the end plate 106 and the ventilation pipe 102 is slid into the interior of the box body 101, the end plate 27 and the end plate 106 clamp the edge of the slide plate 501. When installing the slide plate 501, the air inlet end of the ventilation pipe 102 is slid out of the box body 101 for a section, and one side of the slide plate 501 is aligned with one side of the end plate 106, and the slide plate 501 is slid toward the end plate 106. 1. At this time, the U-shaped edge of the slide plate 501 is stuck in the side position of the end plate 16. As the slide plate 501 slides, when the slide plate 501 and the end plate 16 are in the overlapped state, the ventilation pipe 102 slides into the interior of the box body 101. At this time, the end plate 2 7 and the end plate 16 clamp the edge of the slide plate 501 to fix the position of the filter screen 502. Similarly, when removing, it is only necessary to slide the air inlet end of the ventilation pipe 102 out of the box body 101 for a while again, and then the end plate 2 7 and the end plate 16 eliminate the clamping of the edge position of the slide plate 501. In this state, the slide plate 501 is moved to one side, so that the slide plate 501 can be quickly disassembled to clean the filter screen 502, thereby improving the efficiency of disassembling and cleaning the filter screen 502.

[0034] like Figure 3 As shown, in order to further fix the slide plate 501 on the end plate 1 6, a plurality of limit posts 8 are evenly distributed on both sides of the slide plate 501, and a plurality of limit grooves 9 cooperating with the limit posts 8 are opened on the end plate 2 7. When the end plate 1 6 and the end plate 2 7 clamp the slide plate 501, the limit posts 8 are inserted into the corresponding limit grooves 9 to prevent the slide plate 501 from moving.

[0035] Example 3

[0036] like Figure 6-Figure 8As shown, on the basis of Example 1, in order to prevent impurities from entering through the air outlet of the ventilation duct 102 to ensure the cleanliness of the ventilation duct 102, this embodiment has a mounting frame 13 fixedly installed in the ventilation duct 102 and close to the air outlet of the ventilation duct 102. Two dampers 14 are symmetrically fixedly connected to the mounting frame 13. When the fan 2 is running, the air in the ventilation duct 102 flows, and the flowing air will push open the two dampers 14. In this way, the two dampers 14 are opened to facilitate the circulation of air in the ventilation duct 102. When the fan 2 stops, the two dampers 14 are closed. At this time, impurities can be prevented from entering through the air outlet of the ventilation duct 102 to ensure the cleanliness of the ventilation duct 102.

[0037] like Figure 6-Figure 8 As shown, in order to ensure that the two dampers 14 are closed after the fan 2 stops, a stopper 15 for limiting the opening and closing angles of the two dampers 14 is connected to the mounting frame 13, and a cushion block 16 is fixedly connected to the bottom of the box body 101, and the cushion block 16 gradually thickens from front to back. Figure 6 As shown, under the action of the cushion block 16, the detection box 1 is tilted as a whole, causing the air inlet of the ventilation duct 102 to be at a lower position and the air outlet to be at a higher position, and under the action of the blocking rod 15, the opening angle of the two dampers 14 is limited, and the rotation angle of the two dampers 14 is less than ninety degrees. In this way, when the fan 2 stops, the damper 14 resets and rotates under the action of its own gravity, thereby realizing automatic closing of the damper 14.

[0038] like Figure 2 As shown, in order to facilitate the installation of the fan 2 and the detector 3 inside the ventilation duct 102, a mounting frame 4 is provided inside the ventilation duct 102, and the fan 2 and the detector 3 are installed on the mounting frame 4, as shown in FIG. Figure 2 As shown, through the support of the mounting frame 4, the fan 2 is supported in the middle position of the ventilation duct 102, the air suction direction of the fan 2 is facing the air inlet position of the ventilation duct 102, and the support rod separated from the mounting frame 4 supports the detector 3 in the center position of the ventilation duct 102. At this time, it can be ensured that the detector 3 can fully contact the gas flowing in the ventilation duct 102.

[0039] like Figure 4 , Figure 5 As shown, in order to fix the ventilation pipe 102 inside the box body 101, side grooves 103 are provided on both sides of the ventilation pipe 102, and the insides of the two side grooves 103 are rotatably connected to the rotating rods 10 through springs 11, and a clamping block 12 is provided on the side wall of the rotating rod 10, and a clamping groove 104 is provided on the inner wall of the box body 101. When the ventilation pipe 102 is installed inside the box body 101, the clamping block 12 is clamped inside the clamping groove 104;

[0040] like Figure 5As shown, the front end of the rotating rod 10 is rotatably connected to the inside of the side groove 103, and the spring 11 presses the rear end of the rotating rod 10 toward the outside of the side groove 103. At this time, after the ventilation pipe 102 is installed in the inside of the box 101, the block 12 is clamped in the inside of the clamping groove 104, so that the ventilation pipe 102 can be quickly fixed in the box 101. When removing the ventilation pipe 102, it is only necessary to press the rear end of the rotating rod 10 into the side groove 103. In this state, the ventilation pipe 102 can be quickly pulled out of the box 101.

[0041] A controller 17 for controlling the operation of the fan 2 and the detector 3 and a battery module 18 for providing electric energy are installed in the box 101 . The battery module 18 is electrically connected to the fan 2 , the detector 3 and the controller 17 .

[0042] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents.
