Description

Technical Field

[0001] This utility model belongs to the field of atmospheric pollution monitoring and sampling technology, specifically referring to an atmospheric pollution monitoring and sampling device. Background Technology

[0002] With the acceleration of urbanization and the emission of various pollutants exceeding standards, the air quality in cities is deteriorating. This has led people to pay more attention to urban air pollution control. The monitoring and control of air pollution requires the use of sampling devices to collect air samples.

[0003] Existing methods for air pollution monitoring and sampling primarily involve directly drawing air into sampling bottles via an intake structure. However, traditional sampling bottles have a simple structure that only stores air and lacks a sealing structure to prevent leakage after sampling. Furthermore, it is inconvenient to switch the support method according to sampling needs, allowing the sampling device to be supported on the ground or carried by the user. Additionally, it is difficult to monitor wind direction in real time and adjust the orientation of the sampling device to assist in air collection. Therefore, there is an urgent need for an air pollution monitoring and sampling device to solve the above problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that current atmospheric pollution monitoring sampling lacks a sealing structure for the sampling bottle to prevent air leakage. Furthermore, it is inconvenient to adapt the sampling device to various support methods for ground support, handheld portability, and real-time wind direction adjustment.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: an air pollution monitoring sampling device includes an air intake fan, an air supply pipe is fixedly connected to the air outlet of the air intake fan, a sampling bottle is threadedly connected to the air outlet of the air supply pipe, a sealing structure extending into the sampling bottle is fixedly connected to the bottom of the air supply pipe for opening and closing the air inlet of the sampling bottle, and the sealing structure includes a spring fixed in the middle of the bottom wall of the sampling bottle, and a sealing plate is fixedly connected to the upper end of the spring;

[0006] The lower end of the gas supply pipe is fixedly sleeved with a support structure located above the sampling bottle, which supports the sampling device for landing and holding it together. The support structure includes a fixed base fixedly sleeved on the lower end of the gas supply pipe, and support rods are rotatably connected to the four corners of the fixed base through a rotating shaft. The upper end of the gas supply pipe is fixedly sleeved with a wind measuring structure for determining the wind direction.

[0007] Furthermore, a connecting plate is fixedly connected to the air outlet at the lower end of the gas transmission pipe, and a top ring is fixedly connected to the bottom of the connecting plate, with the lower end face of the top ring abutting against the upper end face of the sealing plate.

[0008] Furthermore, a collar is fixedly sleeved at the lower end of the support rod, and a connecting rod perpendicular to the collar axis is fixedly connected to the side wall of the collar, and a support disc is fixedly connected to a set of the connecting rods.

[0009] Furthermore, the fixed base consists of a set of circular rings and four sets of square plates extending outward from the circular rings, with the pivot on the support rod connected to the end of the square plates. The side wall of the support plate has through holes evenly distributed in a circle to cooperate with the other three sets of connecting rods.

[0010] Furthermore, the wind measurement structure includes a sleeve fixedly fitted to the upper end of the gas transmission pipe, a support rod fixedly connected to the top of the sleeve, a limiting disc fixedly connected to the upper half of the support rod, and a flag rotatably fitted on the support rod between the two sets of limiting discs.

[0011] Preferably, a dust filter cover is fitted onto the air inlet of the suction fan, multiple sets of transparent shells are fixed to the side wall of the sampling bottle, an external thread is provided on the outer side wall of the air outlet of the air supply pipe, and an internal thread is provided on the inner side wall of the air inlet of the sampling bottle to match the external thread on the air supply pipe.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] 1. Rotate the sampling bottle on the gas supply tube. The top ring enters the sampling bottle and presses the sealing plate to open the air inlet of the sampling bottle. Turn on the suction fan to draw in the air and collect it into the sampling bottle. Remove the sampling bottle from the gas supply tube. The top ring leaves the sealing plate, causing the spring to rebound and drive the sealing plate to rise, sealing the air inlet of the sampling bottle. This achieves the purpose of sealing the sampling bottle to prevent the collected air from leaking.

[0014] 2. Rotate each set of support rods outward to tilt them and let their upper ends abut against the fixed base to support the device on the ground. Rotate each set of support rods together to insert each set of connecting rods into the support plate. The support rods are then brought together for easy hand-holding and portability by the user. This achieves the purpose of stabilizing and porting the device by switching between different support methods.

[0015] 3. After the flag is blown by the wind, it rotates on the support pole to adjust its direction, so that users can easily check the wind direction in real time and adjust the direction of the air intake fan to be opposite to the wind direction to accelerate air intake sampling.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 , 2 As shown in Figure 4, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: An air pollution monitoring sampling device includes an air intake fan 1, a dust filter cover for filtering dust particles in the air is sleeved at the air inlet of the air intake fan 1, an air supply pipe 2 is fixedly connected at the air outlet of the air intake fan 1, an external thread is provided on the outer side wall of the air outlet of the air supply pipe 2, a sampling bottle 3 is threadedly connected at the air outlet of the air supply pipe 2, a number of transparent shells for users to view the inside of the sampling bottle 3 are fixedly connected on the side wall of the sampling bottle 3, an internal thread is provided on the inner side wall of the air inlet of the sampling bottle 3 that matches the external thread on the air supply pipe 2, the air inlet of the sampling bottle 3 can be connected and fixed by rotating the air inlet of the sampling bottle 3 clockwise at the air outlet of the air supply pipe 2, and similarly, the sampling bottle 3 can be detached from the air supply pipe 2 by rotating it counterclockwise.

[0024] A sealing structure 4 for opening and closing the air inlet of the sampling bottle 3 is fixedly connected to the bottom of the gas supply pipe 2 and extends into the sampling bottle 3. The sealing structure 4 includes a spring 41 fixed to the middle of the bottom wall of the sampling bottle 3, a sealing plate 42 fixedly connected to the upper end of the spring 41, a connecting plate 43 fixedly connected to the lower end of the gas supply pipe 2, a top ring 44 fixedly connected to the bottom of the connecting plate 43, and the lower end face of the top ring 44 abutting against the upper end face of the sealing plate 42. When the sampling bottle 3 is rotated clockwise at the air outlet of the gas supply pipe 2, the top ring 44 gradually extends into the sampling bottle 3 and presses down the sealing plate 42. At the same time, the spring 41 also contracts, so after the suction fan 1 is turned on, air can be transported by the air supply pipe 2 and enter the sampling bottle 3 through the gap between the connecting plate 43 and the top ring 44 for collection. After collection, the sampling bottle 3 is rotated counterclockwise to detach from the air supply pipe 2, so the sealing plate 42 is detached from the top ring 44, which can cause the spring 41 to rebound, thereby lifting the sealing plate 42 to the air inlet of the sampling bottle 3. Since the shaft diameter of the sealing plate 42 is the same as the inner diameter of the air inlet of the sampling bottle 3, the air inlet of the sampling bottle 3 can be sealed, thereby preventing the collected air from leaking.

[0025] Example 2

[0026] like Figure 1-2 As shown, in order to achieve the purpose of switching between different support methods for the sampling device, such as ground support or handheld portability, a support structure 5 is fixedly sleeved at the lower end of the gas supply pipe 2, located above the sampling bottle 3, for both ground support and handheld use of the sampling device. The support structure 5 includes a fixed base 51 fixedly sleeved at the lower end of the gas supply pipe 2. Support rods 52 are rotatably connected to the four corners of the fixed base 51 via pivots. The fixed base 51 consists of a set of circular rings and four sets of square plates extending outward from the circular rings, with pivots on the support rods 52 connected to the ends of the square plates. A collar 53 is fixedly sleeved at the lower end of the support rod 52, and a ring is fixedly connected to the side wall of the collar 53. A connecting rod 54 is vertically arranged along axis 53. A support plate 55 is fixed to one set of connecting rods 54. The side wall of the support plate 55 has through holes evenly distributed around its circumference to cooperate with the other three sets of connecting rods 54. When each set of support rods 52 is rotated outward and tilted, the other three sets of connecting rods 54 are pulled out from the support plate 55. When the top of the support rod 52 abuts against the square plate, the device can be stably supported on the ground. When each set of support rods 52 is rotated inward and brought together, the other three sets of connecting rods 54 are inserted into the support plate 55 and brought together and fixed. This makes it convenient for the user to hold the support plate 55 and each set of support rods 52 to grip the device for subsequent carrying and transportation or hand-held sampling.

[0027] Example 3

[0028] like Figure 1-2As shown, in order to facilitate real-time monitoring of wind direction and adjustment of the sampling device orientation to match the wind direction, a wind measuring structure 6 for determining wind direction is fixedly sleeved at the upper end of the air supply pipe 2. The wind measuring structure 6 includes a sleeve 61 fixedly sleeved at the upper end of the air supply pipe 2, a support rod 62 fixedly connected to the top of the sleeve 61, and a limiting disc 63 fixedly connected to the upper half of the support rod 62. A flag 64 located between the two sets of limiting discs 63 is rotatably sleeved on the support rod 62. When the wind blows the flag 64, the flag 64 will rotate on the support rod 62 with the wind direction. The wind direction can be determined according to the swing direction of the flag 64. Then, the air intake fan 1 is adjusted to a position opposite to the wind direction. After turning on the air intake fan 1, the air can be easily and quickly drawn in and collected.
