Description

Technical Field

[0001] The present invention relates to the technical field of environmental detection, and specifically, it is a gas detection device for environmental detection. Background Art

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure the environmental quality status. Environmental monitoring is to monitor and measure the indicators reflecting environmental quality to determine the pollution status and the level of environmental quality. Among them, in environmental detection, the detection of gases in the environment is crucial and directly affects the level of environmental quality.

[0003] Most of the current gas detection devices for environmental detection collect air through a pump fan and then detect it through a detection chip. Since the air quality at each location in the environment may be different, when detecting the gases in the environment, the detector needs to move the detection device through a moving vehicle body to detect the air at multiple different locations. When the detector reaches the next detection location, due to the gas residue at the previous detection point, the detection data at the next location will be deviated. Summary of the Invention

[0027] Embodiment

[0028] As Figures 1 to 3 shown, a gas detection device for environmental detection includes: an air suction box 1, a sphere 2, a drive box 3, a first transmission gear 4, a second transmission gear 5, and a rotating cylinder 8. As Figure 1 shown, an air suction pipe 11 at the front end of the air suction box 1 is connected to an air suction head 14 through a hose 13. A first fan 12 is arranged inside the air suction box 1. A fan drive gear 121 is arranged on the output shaft of the first fan 12, and a connecting pipe 15 is connected to the bottom. The sphere 2 is rotatably arranged on a first bracket 21 at the top of the air suction box 1. The sphere 2 is embedded in the top of the first bracket 21 and can rotate. Connecting rods are oppositely arranged at both ends of the sphere 2. One end of the connecting rod is connected to the air suction head 14. When rotating, the air suction head 14 is controlled to start shaking, improving the air suction space and range. A sphere drive gear 22 is arranged on the connecting rod at the other end of the sphere 2. As Figure 2As shown in the figure, a driving rod 31 is arranged inside the driving box 3, and a driven rod 33 penetrates through the top. The driving rod 31 is used to drive the fan driving gear 121 and the driven rod 33. The driving rod 31 first drives the fan driving gear 121, and then drives the driven rod 33 through the fan driving gear 121. The first transmission gear 4 is arranged between the driven rod 33 and the sphere driving gear 22 through the second bracket 43. The first transmission gear 4 is driven by the driven rod 33, and the first transmission gear 4 drives the sphere driving gear 22 to make the sphere 2 rotate. The second transmission gear 5 is arranged on the side of the driven rod 33 away from the first transmission gear 4 through the third bracket 52. The rotating cylinder 8 is arranged on the support plate 10 through the fourth bracket 81. One end of the center is connected to one end of the rotating shaft 82, and the other end of the rotating shaft 82 is connected to the side surface of the driving box 3. A rotating cylinder gear 7 is sleeved on the rotating shaft 82. A plurality of air inlet pipes 83 are arranged inside the rotating cylinder 8, and one of the air inlet pipes 83 transmits gas to the detection box 9 through the communication pipe 15 for detection.

[0029] Specifically, the driving rod 31 includes a driving gear 32 arranged at the end of the driving rod 31. The driven rod 33 includes: a second driven gear 332 and a first driven gear 331. The second driven gear 332 is arranged at the top of the driven rod 33. The first driven gear 331 is arranged at the bottom of the driven rod 33. The first driven gear 331 meshes with the fan driving gear 121, and the fan driving gear 121 meshes with the driving gear 22.

[0030] Specifically, the second driven gear 332 drives the first transmission gear 4 to rotate. The first transmission gear 4 includes: a disk-shaped bevel gear 41 and a third driven gear 42. The sphere driving gear 22 meshes with the helical teeth on the periphery of the disk-shaped bevel gear 41. The third driven gear 42 meshes with the second driven gear 332.

[0031] Specifically, the second driven gear 332 is used to drive the second transmission gear 5. The second transmission gear 5 includes: a fourth driven gear 51 and a fifth driven gear 53. The fourth driven gear 51 meshes with the second driven gear 332. The fifth driven gear 53 is coaxially arranged with the fourth driven gear 51 and is used to drive the rotating cylinder gear 7. A reduction gear 6 is arranged between the fifth driven gear 53 and the rotating cylinder gear 7, and the reduction gear 6 and the rotating cylinder gear 7 are intermittently driven.

[0032] In use, an external motor is connected through the driving rod 31 to rotate the driving rod 31, causing the driving gear 32 to rotate. Therefore, the fan driving gear 121 rotates, causing the first fan 12 to start working. The first driven gear 331 rotates, causing the driven rod 33 to rotate, causing the second driven gear 332 to rotate, causing the third driven gear 42 to rotate, and thus the disk-shaped bevel gear 41 starts to rotate. Then, the sphere driving gear 22 starts to rotate around the periphery of the disk-shaped bevel gear 41. Since the position of the sphere 2 is restricted by the first bracket 21, as Figure 1 shown, the sphere 2 is rotated through the connecting rod, so that the connecting rod drives the suction head 14 to suck gas in a larger range;

[0033] When the second driven gear 332 rotates, the fourth driven gear 51 starts to rotate, that is, the coaxial fifth driven gear 53 rotates. Then, the speed is reduced through the reduction gear 6. Through the intermittent transmission of the reduction gear 6 and the drum gear 7, after the suction head 14 rotates a fixed number of turns, the drum gear 7 drives the drum 8 to rotate once through the rotating shaft 82, that is, the intake pipe 83 is replaced once. The connecting pipe 15 only aligns with and communicates with one of the intake pipes 83, as Figure 2 shown. The connecting pipe 15 only aligns with the intake pipe 83 at the lowest position. Therefore, when the rotating shaft 82 drives the drum 8 to rotate once and the intake pipe 83 is replaced, the device needs to be moved to the next detection point.

[0034] Preferably, in order to improve the detection effect and the accuracy of data, it further includes: a detection box 9. The detection box 9 is arranged on one side of the drum 8 and internally provided with a second fan 92. The second fan 92 rotates through an external motor, and the purpose of rotation is to suck the gas in the intake pipe 83. The second fan 92 is located at the end of one of the intake pipes 83. In Figure 2 it, the second fan 92 is located behind the intake pipe 83 at the lowest end, and a detection sensor 91 is arranged behind the second fan 92 to quickly detect the gas transmitted into the detection box 9.

[0035] Preferably, in order to more conveniently display data, the detection sensor 91 is connected to a display screen 93, and the display screen 93 is located outside the detection box 9.

[0036] Preferably, in order to detect the gas at different heights in the environment, the device further includes: a base 103 and a lifter 101. The base 103 is arranged below the support plate 10; the lifter 101 is arranged between the base 103 and the support plate 10.

[0037] Preferably, in order to improve the lifting stability and collect and detect the gas in different directions at the same height, the lifter 101 is a scissor lifter, and a turntable 102 is arranged between its bottom and the base 103.

[0038] Preferably, in order to retain samples of the collected gas, after the detection is completed, the data detected during real-time detection can be detected and examined to further improve the accuracy of the data. Then, based on the samples, the components at the positions with poor gas quality can be analyzed, and corresponding solutions can be taken to improve and enhance the air quality. The intake pipe 83 includes: a detection pipe 831 and a collection pipe 832. The detection pipe 831 is a straight pipe with a hollow interior; the collection pipe 832 is a straight pipe with a hollow interior and is provided with a plurality of adsorption balls 8321 arranged in an interleaved manner.

[0039] Preferably, to prevent gas leakage and inaccurate detection data when the rotary drum 8 rotates, as Figure 3 shown, an annular groove 84 is formed on the side of the rotary drum 8 close to the suction box 1. The intake port of the intake pipe 83 is located in the annular groove 84, and the outlet end of the connecting pipe 15 is also located in the annular groove 84. A sealing ring 841 is provided on the groove wall of the annular groove 84.

[0040] The above-disclosed are only several specific preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
