Description

Technical Field

[0001] The present invention relates to the technical field of environmental detection, and particularly to a dynamic detection device and method for the environment of a purification workshop. Background Art

[0002] In high-tech industries such as semiconductor manufacturing, precision optical instrument production, and medical preparation research and development, the environmental quality inside a purification workshop is like the lifeline of the production process. Any slight change in the air quality may directly affect the product quality, and in severe cases, may even lead to production stagnation or safety accidents. Therefore, precise and dynamic detection of the purification workshop environment has become a core link to ensure production quality and safety.

[0003] Currently, the deficiencies of traditional purification workshop environment detection devices in terms of detection accuracy are becoming increasingly prominent. Among them, the air disturbance problem caused by the direct entry of the detection device into the detection area has become a key factor restricting the improvement of detection accuracy.

[0004] Most traditional detection devices directly enter the detection area to achieve multi-position detection. Their own volume and moving speed will form a physical barrier and impact on the air in the detection area. This not only changes the local air flow direction but also generates air turbulence, resulting in the air composition around the sampling not being able to truly reflect the original state of the workshop, the collected samples being distorted, and ultimately leading to deviations in the detection results.

[0005] When some portable detection devices are in use, the detection personnel need to hold the device and directly enter the detection area. The movement and breathing of the human body will interfere with the air in the detection area. Coupled with the operation of the detection device itself, the two will superimpose to cause more complex disturbances to the air in the detection area. The exhaled gas of the detection personnel may mix into the sampling area, affecting the purity of the sample. At the same time, the operation of the device may change the temperature and humidity of the surrounding air, making the detection data unable to accurately reflect the real environment of the workshop.

[0006] There are also some large detection devices that need to open the protective door when entering the detection area, which will cause an instant imbalance in the air pressure inside and outside the workshop. The unclean air outside the workshop may take the opportunity to enter, and at the same time, the air flow impact during the entry of the device will greatly change the air distribution in the detection area. The samples collected in this case cannot represent the real environment inside the purification workshop, and the data between different detection points lack consistency and comparability, making it difficult to accurately evaluate the workshop environment.

[0007] Due to the air disturbance caused by the direct entry of traditional detection devices into the detection area, not only the reliability of a single detection result is reduced, but also the long-term monitoring data loses continuity and reference value. This seriously hinders the scientific evaluation and effective regulation of the purification workshop environment.

[0008] Therefore, developing a new device and method that can avoid disturbing the air when entering the detection area and thus achieve high-precision detection has become a difficult problem that urgently needs to be solved in the field of purification workshop environment detection. The dynamic detection device and method for the purification workshop environment of the present invention are committed to resolving this dilemma and providing a more accurate and efficient solution for the purification workshop environment detection. Summary of the Invention

[0009] In order to solve the problem of air disturbance caused by the traditional detection device directly entering the detection area, the purpose of the present invention is to provide a dynamic detection device and method for the purification workshop environment.

[0011] Preferably, the position driving mechanism includes four suspension rods fixedly installed on the top of the workshop and symmetrically arranged. Sleeves are rotatably sleeved on the outer walls of the four suspension rods near the bottom. Four electric retractable winches are installed at the bottoms of the four sleeves. Four pull ropes are wound in the four electric retractable winches. The ends of the four pull ropes are commonly fixedly connected with a first electric push rod. The bottom of the first electric push rod is fixedly connected with the top of the U-shaped frame. The telescopic end of the top of the first electric push rod is fixedly connected with a lifting disc.

[0012] Preferably, a column is fixedly connected to the center of the bottom of the inner cylinder. A plurality of first connecting plates are fixedly connected to the outer wall of the column. A connecting block is fixedly connected to the top of the first connecting plate. An arc-shaped hole is opened on the side wall of the connecting block, and the arc-shaped hole is slidably sleeved on the outer wall of the spiral part of the spiral shape memory alloy tube. The axes of the cylindrical end of the horn-shaped heating tube, the multi-section telescopic tube, the fixed cylinder, the inner cylinder, and the column coincide.

[0013] Preferably, a second connecting plate is fixedly connected to the outer wall of the horn-shaped heating tube, and the second connecting plate is fixedly connected to the outer wall of the cylinder. The horn-shaped heating tube is arranged in a double layer, with the outer layer being a heat insulation layer and the inner layer being a heat conduction layer. A spiral heating rod is arranged between the heat insulation layer and the heat conduction layer.

[0014] Preferably, the adjusting mechanism includes a first motor fixedly installed in the U-shaped frame. The output end of the first motor is axially connected with a first gear. The first gear meshes with a gear ring rotatably sleeved on the outer wall of the fixed cylinder. The top surface of the gear ring slidably and rotatably penetrates through a driving rod. A limiting plate is fixedly arranged at the bottom of the driving rod, and a strip-shaped block is fixedly connected to the top of the driving rod. The bottom of the strip-shaped block is fixedly connected to the top surface of the inner cylinder.

[0015] Preferably, a connecting pipe is fixedly installed on the outer wall of the fixed cylinder. The two ends of the connecting pipe are respectively communicated with the air detector and the spiral shape memory alloy tube. The diameter of the spiral shape memory alloy tube is 3 - 6 mm.

[0016] Preferably, the conical pendulum mechanism includes a fixed pipe fixedly installed at the center of the bottom of the fixed cylinder. The bottom port of the fixed pipe is rotatably butted with a turntable. A strip-shaped hole is opened at the bottom of the turntable. A second electric push rod is fixedly installed on the inner wall of the strip-shaped hole. The telescopic end of the second electric push rod is fixedly connected with a rectangular block slidably connected to the inner wall of the strip-shaped hole. A guiding hole is opened at the bottom of the rectangular block. The outer walls of the straight pipe and the spiral shape memory alloy tube are slidably matched with the inner wall of the guiding hole. The conical pendulum mechanism further includes a second motor fixedly installed at the bottom of the fixed cylinder. The output end of the second motor is axially connected with a second gear. Tooth teeth are opened on the outer wall of the turntable, and the tooth teeth mesh with the second gear.

[0017] The using method of the purification workshop environment dynamic detection device includes the following steps:

[0018] Step 1, the position driving mechanism adjusts the position of the U-shaped frame so that it moves above the position to be detected;

[0019] Step 2, the horn-shaped heating tube heats up. The adjusting mechanism drives the inner cylinder to rotate and rise. The spiral part of the spiral shape memory alloy tube enters the horn-shaped heating tube for heating. Thermoelastic martensite phase transformation occurs inside the spiral shape memory alloy tube inside the horn-shaped heating tube and it becomes straight. As the inner cylinder rises, the straightened memory alloy tube passes through the bottom of the fixed cylinder, and the conical pendulum mechanism moves downward. After the straight pipe reaches the detection height, the adjusting mechanism stops driving the inner cylinder; at the same time, the horn-shaped heating tube stops heating;

[0020] Step 3, the air detector extracts the air at the detection position through the straight pipe and the spiral shape memory alloy tube. At the same time, the conical pendulum mechanism drives the straightened memory alloy tube below the fixed cylinder to make a conical swing; the air detector detects the extracted air.

[0021] Step 4: After the detection is completed, the horn-shaped heating tube continues to heat. The inner cylinder is rotated and lifted again by the adjusting mechanism, then the straight tube continues to descend to reach the next detection position in this vertical direction, and the detection continues;

[0022] Step 5: Repeat Step 4 to sample and detect the air at different heights in the vertical direction;

[0023] Step 6: After the detection is completed, the cold air blower blows cold air into the interior of the inner cylinder. The cold air enters the fixed cylinder from the bottom of the inner cylinder. The shape memory alloy tube in the straight state of the fixed cylinder returns to the spiral shape when it encounters cold. The straight tube rises until the shape memory alloy tube in the straight state completely returns to the spiral shape, then the spiral shape memory alloy tube is stored in the fixed cylinder. At the same time, the adjusting mechanism drives the inner cylinder to rotate and descend to its original position;

[0024] Step 7: The position driving mechanism adjusts the position of the U-shaped frame to move it above the next detection position, and repeat Steps 2 to 6.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0026] 1. In the present invention, by making the spiral shape memory alloy tube heat up and become straight and extend downward to reach different heights for air sampling, and at the same time, the vertical descent of the spiral shape memory alloy tube will not overly disturb the air in the detection area, making the detection more scientific and accurate.

[0027] 2. In the present invention, through the phase change between the spiral shape and the vertical shape of the spiral shape memory alloy tube, the spiral shape can be stored inside the relatively small fixed cylinder, but a relatively long vertical shape memory alloy tube can be obtained.

[0028] 3. In the present invention, the shape memory alloy tube below the fixed cylinder is driven by a conical pendulum mechanism to make a conical swing, realizing small-range dynamic sampling during the detection process and improving the comprehensiveness of the detection results.

[0029] 4. In the present invention, when the shape memory alloy tube makes a conical swing, due to its own characteristic of a relatively small pipe diameter and the slow swing, it can avoid disturbing the air. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiments

[0039] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0040] Please refer to Figures 1 to 7 . It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limiting conditions under which the present invention can be implemented. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear narration, and are not used to limit the scope under which the present invention can be implemented. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope within which the present invention can be implemented.

[0041] The present invention provides a technical solution: a dynamic detection device for the purification workshop environment, including a position driving mechanism 1, aiming to flexibly and stably adjust the position of the detection device. At the top of the workshop, four suspension rods 101 are symmetrically installed. On the outer wall of each suspension rod 101 near the bottom, a sleeve 102 is rotatably sleeved, thereby reducing friction and wear caused by the movement of the device. An electric retractable reel 103 is installed at the bottom of the four sleeves 102, and each electric retractable reel 103 winds a pulling rope 104. By controlling the retraction and release of the pulling ropes 104 by the four electric retractable reels 103, the horizontal position of the detection device in the workshop can be accurately adjusted.

[0042] The ends of the four pulling ropes 104 are commonly connected to a first electric push rod 105. The first electric push rod 105 can not only perform vertical adjustment, but also its bottom is fixedly connected to the top of the U-shaped frame 2. The telescopic end at the top of the first electric push rod 105 is connected to a lifting disc 106. When the device reaches the detection position, the lifting disc 106 is raised to abut against the top of the workshop, thereby greatly enhancing the stability during the detection process and preventing the device from shaking and affecting the detection result.

[0043] The bottom of the U-shaped frame 2 is fixedly penetrated with a fixed cylinder 3, and the top of the fixed cylinder 3 is threadedly penetrated with an inner cylinder 4. This threaded connection method, combined with the subsequent adjustment mechanism, realizes the lifting operation of the inner cylinder 4. A spiral shape memory alloy tube 5 is slidably sleeved on the outer wall of the inner cylinder 4. This alloy tube has unique thermoelastic martensitic phase transformation characteristics. When heated, it can change from a spiral shape to a straight shape, and when cooled, it returns to a spiral shape.

[0044] A horn-shaped heating tube 6 is installed at the bottom of the inner cylinder 4, and its end is cylindrical. The horn-shaped heating tube 6 has a double-layer structure. The outer layer is a heat insulation layer, and the inner layer is a heat conduction layer. A spiral heating rod is arranged between the two layers. This design can effectively transfer heat to the inside while preventing heat dissipation, ensuring that the spiral shape memory alloy tube 5 can be fully heated. The cylindrical end of the horn-shaped heating tube 6 is rotatably butted with a multi-section telescopic tube 7, which not only ensures the rotational flexibility between the two, but also when the horn-shaped heating tube 6 is lifted or lowered, the multi-section telescopic tube 7 can be correspondingly stretched or compressed.

[0045] A cold air blower 8 installed at the top of the inner cylinder 4 blows cold air into the inner cylinder 4 after the detection is completed, realizing the cooling and reset of the spiral shape memory alloy tube 5. A plurality of air outlet holes are opened at the bottom of the inner cylinder 4, which cooperate with the ventilation holes 9 on the outer wall of the fixed cylinder 3 below the U-shaped frame 2 to realize the circulation of cold air when the cold air blower 8 works.

[0046] The main function of the adjustment mechanism 10 is to drive the inner drum 4 to rotate, thereby achieving its elevation. A first motor 1001 is fixedly mounted within the U-shaped frame 2, its output end axially connected to a first gear 1002. The first gear 1002 meshes with a gear ring 1003, which is rotatably sleeved onto the outer wall of the fixed drum 3. The top surface of the gear ring 1003 slides and rotates through a drive rod 1004. A stop plate is provided at the bottom of the drive rod 1004 to prevent it from disengaging from the gear ring 1003. The top of the drive rod 1004 is fixedly connected to a bar block 1005, which is fixed to the top surface of the inner drum 4. When the first motor 1001 is activated, the gear ring 1003 rotates via the first gear 1002, causing the drive rod 1004 to move in a circular motion around the fixed drum 3, thereby rotating the bar block 1005 and the inner drum 4. Because the fixed drum 3 and the inner drum 4 are threaded together, the inner drum 4 is simultaneously raised and lowered as it rotates.

[0047] The top of the spiral memory alloy tube 5 is fixedly connected to the outer wall of the fixed cylinder 3 and is connected to the air detector 11 fixedly installed on the side wall of the U-shaped frame 2 through the connecting pipe 13. During the detection process, the air detector 11 extracts air from the detection position through the straight pipe 14 and the spiral memory alloy tube 5 and performs component analysis, thereby realizing the detection of the clean room environment.

[0048] The diameter of the spiral memory alloy tube 5 is 3-6 mm.

[0049] The conical pendulum mechanism 12 is used to drive the memory alloy tube below the fixed cylinder 3 to perform a conical swing to expand the detection range. A fixed tube 1201 is fixedly installed at the center of the bottom of the fixed cylinder 3, and its bottom port is rotatably docked with the turntable 1202. A strip hole 1203 is provided at the bottom of the turntable 1202, in which a second electric push rod 1204 is installed, and its telescopic end is connected to a rectangular block 1205, and the rectangular block 1205 can slide in the strip hole 1203. A guide hole 1206 is provided at the bottom of the rectangular block 1205, and the outer wall of the straight tube 14 and the spiral memory alloy tube 5 are slidably matched with the guide hole 1206. A second motor 1207 is also installed at the bottom of the fixed cylinder 3, and its output end is connected to the second gear 1208. The teeth on the outer wall of the turntable 1202 are engaged with the second gear 1208. A second electric push rod 1204 adjusts the position of rectangular block 1205, eccentrically positioning guide hole 1206 relative to the center of turntable 1202. A second motor 1207 then rotates turntable 1202, which in turn drives the memory alloy tube in a conical swing. During operation, the memory alloy tube must be swung slowly to avoid excessive air agitation, which could affect the accuracy of the test results.

[0050] How to use the device:

[0051] Detection position adjustment: Through the position driving mechanism 1, adjust the position of the U-shaped frame 2 to move the detection device above the position to be detected. Control the four electric winding reels 103 to wind and unwind the pull rope 104 to accurately position the horizontal position of the detection device, and then adjust the vertical height through the first electric push rod 105 to ensure that the detection device is aligned with the detection point.

[0052] Detection preparation: Start the horn-shaped heating tube 6, and the spiral heating rod inside it starts to work to heat the spiral shape memory alloy tube 5 inside the inner cylinder 4. At the same time, the adjustment mechanism 10 is started, and the first motor 1001 drives the inner cylinder 4 to rotate and rise. As the inner cylinder 4 rises, the spiral part of the spiral shape memory alloy tube 5 enters the horn-shaped heating tube 6, undergoes a thermoelastic martensitic transformation, and gradually straightens. As the inner cylinder 4 continues to rise, the straightened memory alloy tube passes through the bottom of the fixed cylinder 3 and moves downward through the conical pendulum mechanism 12. When the straight tube 14 reaches the preset detection height, the adjustment mechanism 10 stops working, and the horn-shaped heating tube 6 also stops heating.

[0053] Air detection: The air detector 11 extracts the air at the detection position through the straight tube 14 and the spiral shape memory alloy tube 5 and conducts detection and analysis. At the same time, the conical pendulum mechanism 12 is started, the second electric push rod 1204 adjusts the position of the rectangular block 1205 to make the guide hole 1206 eccentric, and the second motor 1207 drives the turntable 1202 to rotate, driving the memory alloy tube below the fixed cylinder 3 to make a conical swing, expanding the air extraction range and improving the comprehensiveness of detection.

[0054] Detection at different heights: After the detection is completed, start the horn-shaped heating tube 6 again, and the adjustment mechanism 10 drives the inner cylinder 4 to continue rising, so that the straight tube 14 descends to the next detection height, and repeat the air detection steps to realize the detection of air at different heights.

[0055] Device reset: After all detection tasks are completed, start the cold air blower 8 to blow cold air into the inner cylinder 4. The cold air enters the fixed cylinder 3 through the air outlet holes at the bottom of the inner cylinder 4, so that the straightened memory alloy tube returns to its spiral shape when it encounters cold, and the straight tube 14 rises accordingly. When the memory alloy tube completely returns to its spiral shape, it is stored in the fixed cylinder 3. At the same time, the adjustment mechanism 10 drives the inner cylinder 4 to rotate and descend to the initial position.

[0056] Detection of the next detection point: Through the position driving mechanism 1, move the detection device above the next position to be detected, and repeat the above steps to continue the detection.

[0057] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.

A method for using a dynamic detection device for the purification workshop environment, characterized in that, Using the purification workshop environment dynamic detection device according to any one of claims 1-7, comprising the following steps: Step 1, the position driving mechanism (1) adjusts the position of the U-shaped frame (2) to move it above the position to be detected; Step 2, the horn-shaped heating tube (6) is heated. The adjusting mechanism (10) drives the inner cylinder (4) to rotate and rise, and the helical part of the helical shape memory alloy tube (5) enters the horn-shaped heating tube (6) for heating. A thermoelastic martensite phase change occurs inside the helical shape memory alloy tube (5) inside the horn-shaped heating tube (6) and it becomes straight; as the inner cylinder (4) rises, the straightened memory alloy tube passes through the bottom of the fixed cylinder (3), and the conical pendulum mechanism (12) moves downward; after the straight pipe (14) reaches the detection height, the adjusting mechanism (10) stops driving the inner cylinder (4); at the same time, the horn-shaped heating tube (6) stops heating; Step 3: The air detector (11) extracts the air at the detection position through the straight pipe (14) and the spiral shape memory alloy pipe (5). Meanwhile, the cone pendulum mechanism (12) drives the straightening state memory alloy pipe below the fixed cylinder (3) to make a conical swing; the air detector (11) detects the extracted air. Step 4: After the detection is completed, the horn-shaped heating pipe (6) continues to heat. Then, the inner cylinder (4) is driven to rotate and rise again through the adjusting mechanism (10), so the straight pipe (14) continues to descend to reach the next detection position in the vertical direction and continue the detection. Step 5: Repeat Step 4 to sample and detect the air at different heights in the vertical direction. Step 6: After the detection is completed, the cold air blower (8) blows cold air into the interior of the inner cylinder (4). The cold air enters the fixed cylinder (3) from the bottom of the inner cylinder (4). The straightening state memory alloy pipe in the fixed cylinder (3) returns to the spiral shape when encountering cold. The straight pipe (14) rises until the straightening state memory alloy pipe completely returns to the spiral shape. Then, the spiral shape memory alloy pipe (5) is stored in the fixed cylinder (3). Meanwhile, the adjusting mechanism (10) drives the inner cylinder (4) to rotate and descend to its original position. Step 7: The position driving mechanism (1) adjusts the position of the U-shaped frame (2) to move it above the next position to be detected, and repeat Steps 2 to 6.
