Description

Technical Field

[0002] With the sustained and rapid development of my country's economy, the continuous expansion of urban construction, and the ongoing optimization and adjustment of urban functional layout and industrial structure, many cities have undergone significant changes in environmental conditions, built-up areas, population size and distribution. To ensure residents' respiratory health and the normal and orderly operation of urban life, it is necessary to systematically sample and monitor the atmosphere in different urban areas, thereby better maintaining stable air quality and ensuring the balance of the ecological environment.

[0003] In existing atmospheric sampling equipment, the sampling devices are often installed at high altitudes. After sampling, it is necessary to manually climb the support frame to remove the gas tank after sampling, and then replace it with a new gas tank for the next sampling and storage. The whole replacement process is cumbersome, time-consuming and labor-intensive, which reduces the efficiency of gas tank replacement. At the same time, when the equipment samples at a fixed height, it can only collect gas in a fixed direction at that height, which reduces the sampling accuracy and affects the accuracy of subsequent atmospheric detection results.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 14 As shown, an atmospheric environment detection and sampling device includes: a base 1, a support cylinder 2, a cylindrical cylinder 3, a cover 4, a sampling component 5, a transport component 6, a power motor 7, and a cylindrical shell 8; A support cylinder 2 is vertically fixedly installed on the base 1. A cylinder 3 is fixedly installed on the top of the support cylinder 2. A cover 4 is movably installed on the outer circumference of the cylinder 3, and the cover 4 is close to the top of the support cylinder 2. A sampling component 5 is fixedly installed on the top of the cylinder 3. A transport component 6 is fixedly installed inside the cylinder 3. A power motor 7 is fixedly installed on the inner circumference of the support cylinder 2, and the output end of the power motor 7 is fixedly connected to the sampling component 5. A circular shell 8 is fixedly installed on the outside of the sampling component 5. The power motor 7 drives the transport component 6 to move up and down inside the cylinder 3, and transports and unloads the gas tank. At the same time, the power motor 7 adjusts the sampling range of the sampling component 5.

[0035] The base 1 is made of high-strength, wear-resistant material, providing a stable support foundation for the entire device. A support cylinder 2 is vertically fixed to its top surface using bolts. The support cylinder 2 is made of lightweight alloy material, ensuring structural strength while effectively reducing the overall weight of the device. A cylindrical cylinder 3 is fixedly installed on the top of the support cylinder 2 via a flange connection.

[0036] A cover 4 is hinged to the outer circumference of the cylinder 3 near the top of the support cylinder 2. The connection between the cover 4 and the outer wall of the cylinder 3 is equipped with a sealing ring, which can ensure the airtightness of the inside of the cylinder 3 when closed and prevent external impurities from entering. A sampling component 5 is precisely fixed to the top of the cylinder 3 by a bolt group. The sampling component 5 is responsible for collecting atmospheric samples.

[0037] The round shell 8 is made of a sealed protective material and is fixed to the outside of the sampling component 5 by bolts, forming all-round protection for the sampling component 5. It can effectively resist the erosion of the sampling component 5 by external environmental factors such as wind, rain and dust, and ensure the sampling accuracy and service life of the component.

[0038] The power motor 7 provides the core driving force, which on the one hand drives the transport component 6 to move stably up and down in the vertical direction inside the cylinder 3, realizing the precise transport, loading and unloading of the sampling gas tank, and ensuring the stability and safety of the gas tank during the transfer process; on the other hand, the power motor 7 can adjust the extension distance of the sampling tube 56, thereby flexibly adapting to the sampling needs of different atmospheric environments.

[0039] like Figures 6 to 14 As shown, the sampling assembly 5 includes a rotating screw 51, a fixed disk 52, a sampling disk 53, a rotating disk 54, an air pump 55, a sampling tube 56, a fixing pin 57, a fixing cylinder 58, and a support column 59. The bottom of the rotating screw 51 is fixedly connected to the power motor 7. The rotating screw 51 is located inside the cylinder 3, and the transport component 6 is located outside the rotating screw 51. A connecting shaft 511 is provided at the top of the rotating screw 51, and a cylindrical iron block 512 is provided at the top of the connecting shaft 511. The fixed disk 52 is rotatably mounted on the connecting shaft 511, and the bottom of the fixed disk 52 is fixedly connected to the top of the cylinder 3. Multiple support columns 59 are arranged in a circular array around the axis at the top of the fixed disk 52. A sampling disk 53 is fixedly installed on the top of the multiple support columns 59. The rotating disk 54 is rotatably mounted on the fixed disk 52. Multiple air pumps 55 are arranged in a ring around the top of the fixed disk 52 with the axis as the center. The multiple air pumps 55 are arranged at intervals with the multiple support columns 59. Multiple sampling tubes 56 are arranged in a ring around the top of the sampling disk 53 with the axis as the center. Fixing pins 57 are vertically arranged on the outer circumference of the multiple sampling tubes 56. Multiple fixing cylinders 58 are arranged in a ring around the top of the sampling disk 53 with the axis as the center. The multiple fixing cylinders 58 are located at the inner ends of the multiple sampling tubes 56. The multiple sampling tubes 56 slide through the outer wall of the circular shell 8.

[0040] The rotating screw 51 serves as the core transmission component, with its bottom precisely fixed to the output end of the power motor 7 via a coupling, ensuring the stability and efficiency of power transmission. The cylindrical iron block 512 is used to cooperate with the subsequent magnetic linkage structure. The fixed disk 52 is rotatably mounted on the connecting shaft 511 via bearings, and its bottom end face is fastened to the top end face of the cylinder 3 with bolts, making the fixed disk 52 a stable support base. The support column 59 is used to achieve horizontal suspension support for the sampling disk 53.

[0041] The sampling tube 56 is made of a corrosion-resistant and airtight material; the fixing pin 57 is used to realize the linkage between the sampling tube 56 and the rotating disk 54. The fixing cylinder 58 is used to hold the elastic telescopic tube 581, ensuring that gas can enter the gas tank while ensuring that the sampling tube 56 can be flexibly extended and retracted to realize sampling operations in different ranges.

[0042] It should be noted that a sensor is fixedly installed at the bottom of the fixed plate 52 to detect the distance of the bottom support ring 63 rising and falling, so as to replace the gas tank in coordination with the movement of the support ring 63.

[0043] like Figure 7 and Figure 13As shown, the fixed disk 52 has multiple air holes 521 arranged in a circular array around its axis. A through circular hole 522 is formed at the center of the fixed disk 52, and the through hole 522 is rotatably engaged with the connecting shaft 511. Symmetrical circular grooves 523 are formed on the inner walls of the multiple air holes 521. First electromagnetic blocks 524 are respectively arranged on the inner walls of the symmetrical circular grooves 523. First sliding blocks 525 are slidably arranged inside the symmetrical circular grooves 523. A first compression spring 526 is provided on the outer side of the first electromagnetic block 524 and the first sliding block 525. An arc-shaped clamping block 527 is provided at the end of the first sliding block 525 away from the first electromagnetic block 524. The arc-shaped clamping blocks 527 are symmetrically located inside the air holes 521. A second compression spring 529 is provided inside the multiple air holes 521. One end of the multiple second compression springs 529 is fixedly connected to the end of the air hole 521, and the other end is provided with an elastic rubber ring 528. The elastic rubber ring 528 is located above the symmetrical arc-shaped clamping blocks 527.

[0044] The air vent 521 provides a channel for positioning and sealing the top of the gas tank, and the number of air vents 521 matches the number of gas tanks to be transported. To ensure that the gas tank can be fixed to the bottom of the fixing plate 52 after replacement, the opening of the gas tank needs to be fixed by symmetrical arc-shaped clamping blocks 527, and the gas tank is fixed by the elastic potential energy of the first compression spring 526. When the gas tank is removed, the magnetic field generated by the first electromagnetic block 524 attracts the first sliding block 525 to move, thereby causing the symmetrical arc-shaped clamping blocks 527 to move away from each other and disengage from the opening of the gas tank, thus realizing the disassembly of the gas tank.

[0045] It should be noted that the elastic rubber ring 528 slides in a sealed manner within the air hole 521. When installing the gas canister, the elastic potential energy of the second compression spring 529 pushes the elastic rubber ring 528 tightly against the gas canister opening, thereby ensuring the overall sealing performance. Simultaneously, the gas canister opening utilizes existing technology; the pressure from the air pump 55 can open the opening and allow gas to enter. After gas entry, the opening is sealed by its own structure. The elastic rubber ring 528 is made of aging-resistant, high-sealing rubber material, and its inner diameter matches the inner diameter of the gas canister opening. The inner wall of the arc-shaped clamping block 527 conforms to the outer contour arc of the gas canister opening, and the symmetrically positioned arc-shaped clamping blocks 527 are located inside the air hole 521, allowing for clamping and releasing of the gas canister opening under the action of the first sliding block 525.

[0046] like Figure 11 As shown, a circular hole 531 is provided at the center of the sampling disk 53, and multiple arc-shaped grooves 532 are arranged in a ring around the top of the sampling disk 53 with the axis as the center, and multiple sampling tubes 56 are respectively slidably located inside the multiple arc-shaped grooves 532.

[0047] The diameter of the circular hole 531 is matched with the outer diameter of the cylindrical iron block 512 at the top of the connecting shaft 511, providing clearance for the cylindrical iron block 512 without affecting the stable installation of the sampling plate 53. The number of arc-shaped grooves 532 corresponds one-to-one with the number of sampling tubes 56, and the width and depth of the arc-shaped grooves 532 are matched with the cross-sectional dimensions of the sampling tubes 56. The curvature of the grooves is precisely designed according to the preset sliding trajectory of the sampling tubes 56. Multiple sampling tubes 56 are slidably embedded in multiple arc-shaped grooves 532. The arc-shaped grooves 532 can guide and limit the sliding of the sampling tubes 56, ensuring that the sampling tubes 56 move smoothly along the preset trajectory and avoiding deviation or jamming.

[0048] like Figure 8 As shown, the rotating disk 54 has multiple arc-shaped through holes 541 arranged in a ring around the axis, and multiple fixing pins 57 are respectively slidably located inside the multiple arc-shaped through holes 541. An electromagnetic post 513 is provided at the center of the rotating disk 54. The electromagnetic post 513 is coaxial with the cylindrical iron block 512, and a gap is left between the electromagnetic post 513 and the cylindrical iron block 512.

[0049] The number of arc-shaped through holes 541 corresponds one-to-one with the number of fixing pins 57 on the sampling tube 56. Through the sliding engagement of the fixing pins 57 and the arc-shaped through holes 541, the rotational motion of the rotating disk 54 can be converted into the radial sliding motion of the sampling tube 56, achieving precise control of the extension and retraction of the sampling tube 56. At the same time, an electromagnetic post 513 is set at the center of the rotating disk 54 by bolt fastening. The electromagnetic post 513 is made of a material with excellent magnetic permeability, and its axis is completely coincident with the axis of the cylindrical iron block 512, that is, the two are arranged coaxially. A preset gap is left between the electromagnetic post 513 and the cylindrical iron block 512. This gap can ensure that the magnetic field generated by the electromagnetic post 513 after being energized can effectively attract the cylindrical iron block 512, so that the two can rotate simultaneously, and can also prevent the cylindrical iron block 512 from interfering with the electromagnetic post 513 during rotation when not energized, so that no mechanical collision occurs between the two, ensuring the smoothness of transmission and the service life of the components.

[0050] like Figure 10 and Figure 12 As shown, the tops of the plurality of air holes 521 are respectively connected to air pipes 551 via the air pump 55, and the plurality of air pipes 551 are connected to the plurality of fixed cylinders 58.

[0051] The top of the vent 521 is connected to the output end of the air pump 55 via a flange connection, and a sealing gasket is fitted at the connection to ensure airtightness. The air pump 55 is connected to the air pipe 551, which is connected to the elastic telescopic tube 581 to achieve precise docking of the air output of the air pump 55 with the elastic telescopic tube 581, providing a stable channel for the subsequent delivery of sampling gas.

[0052] like Figure 14 As shown, the sampling tube 56 is provided with a first filter screen 561, a second filter screen 562 and a third filter screen 563 at equal intervals. The mesh size of the first filter screen 561, the second filter screen 562 and the third filter screen 563 decreases step by step. The fixed cylinder 58 is provided with an elastic telescopic tube 581. One end of the elastic telescopic tube 581 is connected to the sampling tube 56 and the other end is connected to the air tube 551.

[0053] It is worth noting that the sampling tube 56 is internally fitted with a first filter screen 561, a second filter screen 562, and a third filter screen 563, which are equidistantly installed along the gas flow direction. All three are made of high-strength, corrosion-resistant polymer filter material, possessing excellent structural stability and filtration performance. The mesh size of the first filter screen 561, second filter screen 562, and third filter screen 563 decreases progressively, forming a multi-stage filtration structure from fine to coarse. This allows for the progressive trapping of impurities of different particle sizes in the air, significantly improving the gas purification effect. The elastic telescopic tube 581 is made of a foldable, flexible sealing material, possessing excellent extensibility and airtightness. It can adapt to the length changes during the radial sliding process of the sampling tube 56, ensuring that the gas transmission channel remains sealed and connected during the extension or retraction of the sampling tube 56, preventing air leakage.

[0054] like Figure 4 and Figure 5 As shown, the transport assembly 6 includes a chassis 61, a slide block 62, a bearing ring 63, a clamping plate 64, and a compression spring 65; The chassis 61 has a plurality of limiting blocks 611 arranged in a ring around its axis. A sliding cylinder block 62 is fixedly installed on the chassis 61. A bearing ring 63 is fixedly installed on the chassis 61 and is located outside the sliding cylinder block 62. The bearing ring 63 has a plurality of circular grooves 631 arranged in a ring around its axis. The plurality of circular grooves 631 are coaxial with the plurality of air holes 521. The inner circumference of the plurality of circular grooves 631 has symmetrically arranged mounting grooves 632. Compression springs 65 are fixedly installed inside the symmetrically arranged mounting grooves 632. Clamping plates 64 are fixedly installed on one end of the symmetrically arranged compression springs 65 inside the circular grooves 631.

[0055] The number of limiting blocks 611 corresponds one-to-one with the number of rectangular grooves 31 on the inner wall of the cylinder 3, and the cross-sectional dimensions of the limiting blocks 611 are precisely matched with the groove width of the rectangular grooves 31, allowing them to be embedded in the rectangular grooves 31 for sliding guidance. The first thread 621 meshes with the external thread of the rotating screw 51, forming a threaded transmission pair, providing a power transmission basis for the lifting and lowering of the transport component 6. The bearing ring 63 is fixedly connected to the chassis 61 by welding to ensure connection strength. The number of circular grooves 631 on the bearing ring 63 corresponds one-to-one with the number of air holes 521 on the fixed plate 52, and multiple circular grooves 631 are coaxially aligned with multiple air holes 521, ensuring that the gas tank can be accurately aligned with the air holes 521 to complete subsequent positioning and sealing during the lifting and lowering process. The clamping plate 64 is made of wear-resistant rubber and can fix the gas tank by compression spring 65, ensuring the stability of the gas tank during the lifting and lowering process. The surface of the clamping plate 64 near the center of the circular groove 631 is an arc-shaped surface that matches the outer wall of the gas tank, which can improve the fit with the gas tank.

[0056] like Figure 4 , Figure 5 and Figure 8 As shown, a first thread 621 is provided on the inner circumference of the sliding cylinder block 62, and the first thread 621 cooperates with the rotating screw 51.

[0057] By precisely engaging the first thread 621 with the external thread on the outer wall of the rotating screw 51, the rotational motion of the rotating screw 51 can be stably converted into the linear lifting motion of the slide block 62, providing a reliable power transmission basis for the lifting of the transport component 6. At the same time, the thread drive has a self-locking characteristic, which can effectively prevent the transport component 6 from accidentally sliding down when it is stationary or carrying a gas tank, thus improving the safety of the device operation.

[0058] like Figure 3 As shown, a plurality of rectangular grooves 31 are arranged in a ring around the axis on the inner circumference of the cylinder 3, and the plurality of rectangular grooves 31 cooperate with the plurality of limiting blocks 611 respectively.

[0059] The length of the rectangular groove 31 covers the maximum lifting stroke of the transport component 6. The number of rectangular grooves 31 corresponds one-to-one with the number of limiting blocks 611 on the chassis 61 of the transport component 6, and plays a sliding guiding role for the transport component 6. It can effectively limit the circumferential rotation of the chassis 61 and the entire transport component 6, ensuring that the transport component 6 only lifts and lowers in the vertical direction, avoiding the synchronous rotation of the sliding cylinder block 62 caused by the rotation of the rotating screw 51, and ensuring the positioning accuracy during the lifting and lowering of the gas tank.

[0060] The working principle of this invention is as follows: When changing the storage gas tank for sampling, firstly, the control unit controls the power motor 7 to start, and the power motor 7 transmits power to the rotating screw 51. The rotating screw 51 drives the connecting shaft 511 and the cylindrical iron block 512 to rotate in the circular through hole 522 of the fixed plate 52 and the circular hole 531 of the sampling plate 53. Since the first thread 621 inside the sliding cylinder block 62 meshes with the rotating screw 51, when the rotating screw 51 rotates, it will drive the axis of the sliding cylinder block 62 to move upward. The limiting block 611 on the bottom plate 61 of the sliding cylinder block 62 will slide in the rectangular groove 31 on the inner wall of the cylinder 3, thereby causing the entire bearing ring 63 to move upward.

[0061] When the support ring 63 moves to the bottom of the gas tank at the bottom of the fixed plate 52, as the support ring 63 continues to rise, the bottom of each gas tank will enter the circular groove 631. The outer wall of the gas tank will come into contact with the clamping plate 64 in the circular groove 631 and squeeze the clamping plate 64, causing the clamping plate 64 to move radially outward. The clamping plate 64 will compress the compression spring 65. When the sensor detects that the bottom of the gas tank is in contact with the bottom of the circular groove 631, the power motor 7 will stop rotating. The control unit controls the first electromagnetic block 524 to be energized and generate a magnetic field. The first electromagnetic block 524 will attract the first sliding block 525 to approach, thereby driving the mutually symmetrical arc-shaped clamping blocks 527 to disengage from the gas tank opening. At the same time, the first compression spring 526 inside the circular groove 523 will be compressed.

[0062] After the symmetrical arc-shaped clamping blocks 527 disengage from the gas cylinder, the second compression spring 529 will use its stored elastic potential energy to push the elastic rubber ring 528 downward and generate a downward thrust on the gas cylinder. Subsequently, the control unit controls the power motor 7 to rotate in the opposite direction and drive the bearing ring 63 to descend slowly. The second compression spring 529 will slowly return to its original position until the elastic rubber ring 528 disengages from the gas cylinder opening. When the bearing ring 63 descends to the cover 4 at the bottom of the cylinder 3, the operator can open the cover 4 and take out the sampled gas cylinders one by one.

[0063] The operator then places a new air canister in. Similarly, as the air canister is placed in, the clamping plate 64 moves outward, compressing the compression spring 65 to secure the air canister and prevent it from loosening during the ascent. After placement, the lid 4 is closed, and the control unit controls the power motor 7 to rotate, driving the entire support ring 63 to move slowly upward. When the top of the air canister contacts the elastic rubber ring 528 and continues to move upward a small distance, the second compression spring 529 will be compressed. At this point, the elastic rubber ring 528 and the air canister opening are sealed, the power motor 7 stops rotating, and the support ring 63 will no longer move upward. Subsequently, the control unit controls the first electromagnetic block 524 to be de-energized, the magnetic field disappears, and the first electromagnetic block 524 will no longer attract the first sliding block 525. The elastic potential energy stored in the first compression spring 526 pushes the symmetrical arc-shaped clamping block 527 and the first sliding block 525 outward, so that the symmetrical arc-shaped clamping block 527 contacts the outer wall of the air canister opening and clamps and secures the air canister.

[0064] Finally, the control unit controls the power motor 7 to rotate in the opposite direction, causing the bearing ring 63 to move downward. As the bearing ring 63 descends, the clamp 64 will detach from the outer wall of the air tank, and the compression spring 65 will return to its original position until the bearing ring 63 returns to the bottom of the cylinder 3, thus completing the entire replacement process.

[0065] During sampling, the control unit controls the electromagnetic column 513 to be energized and generate a large magnetic field according to the required sampling range. This causes the electromagnetic column 513 to attract the cylindrical iron block 512. Subsequently, the control unit controls the power motor 7 to start. By rotating the screw 51, the connecting shaft 511, the cylindrical iron block 512, and the electromagnetic column 513 rotate together at a certain angle. The electromagnetic column 513 will drive the rotating disk 54 to rotate. During the rotation of the rotating disk 54, the fixing pin 57 on the sampling tube 56 will slide in the arc-shaped through hole 541 on the rotating disk 54, thereby driving the sampling tube 56 to move radially outward. The distance of the sampling tube 56 extending is controlled according to the actual required sampling range. When the sampling tube 56 moves radially outward, it will drive the elastic telescopic tube 581 to extend. When the sampling tube 56 extends a certain distance, the power motor 7 stops working.

[0066] The control unit controls the air pump 55 to start and draws outside air into the air tank through the sampling tube 56 under negative pressure for storage. The gas will be filtered step by step through the third filter 563, the second filter 562 and the first filter 561 to remove impurities from the air. Then it enters the air tank through the air tube 551 for storage, thus completing the entire sampling process. After sampling is completed, the power motor 7 rotates in the opposite direction to drive the sampling tube 56 to retract and return to its original position.

[0067] It should be noted that when the first filter screen 561, the second filter screen 562, and the third filter screen 563 are clogged, air can be blown out by the air pump 55 to remove impurities from the first filter screen 561, the second filter screen 562, and the third filter screen 563, thereby improving the efficiency of gas sampling.
