Description

Technical Field

[0001] The present invention relates to the technical field of occupational disease hazard detection, and particularly to a simulation chamber for detecting occupational disease hazard factors. Background Art

[0002] The detection of occupational disease hazard factors refers to detecting and evaluating harmful substances, physical factors, working methods, etc. existing in the working environment to determine the types, concentrations, exposure paths of potential occupational disease hazard factors and the degree of influence on human health. It detects chemical substances, dust, smoke, odor, etc. existing in the air of the workplace, and analyzes by collecting air samples and using gas detector equipment.

[0003] For example, a simulation chamber for detecting occupational disease hazard factors with the publication number of CN220773021U includes a base. A test chamber is fixedly connected to the top of the base. An air flow control box is fixedly connected to the top of the test chamber. Two sliding plates are slidably connected inside the air flow control box. Two springs are fixedly connected between the two sliding plates. A threaded rod is threadedly connected to the top of the air flow control box. The beneficial effect of the present utility model is that by rotating the threaded rod, one of the sliding plates is driven to compress the spring, so that the other sliding plate blocks the air inlet pipe, and the air intake can be controlled. By disassembling and assembling the filter plate, the filtering amount of the filter plate can be controlled. By precisely controlling the size of the air intake, the inhalation behavior of workers in actual work can be simulated, and the exposure level can be evaluated more accurately. This helps to determine the degree of influence of potential occupational disease hazard factors on workers, and greatly improves the operation quality and use efficiency compared with traditional devices.

[0004] During actual detection, the distribution of gas and dust inside the simulation chamber may be uneven, resulting in a deviation between the sampling point data and the true exposure concentration. Summary of the Invention

The first rotating rod 412 penetrates through the simulation chamber body 1 and extends into its interior. A reciprocating thread groove 413 is formed on the outer wall of the first rotating rod 412. A thread sleeve 414 is threadedly connected to the outer wall of the reciprocating thread groove 413. The outer wall of the thread sleeve 414 is rotatably connected to a diffuser 415 through a bearing. By the rotation of the diffuser 415, centrifugal force is generated, and the gas and dust released from the center are radially thrown out from the small holes on the disk surface to form a three-dimensional eddy current, breaking the laminar state of static diffusion. The mixing efficiency is three to five times higher than that of static diffusion. A turntable 416 is fixedly connected to the outer wall of the first rotating rod 412. A telescopic rod 417 is fixedly connected to the outer wall of the turntable 416. The telescopic end of the telescopic rod 417 is fixedly connected to the top of the diffuser 415. The motor 411 drives the first rotating rod 412 to rotate. When the first rotating rod 412 rotates, it will drive the turntable 416 to rotate. By the rotation of the turntable 416, the telescopic rod 417 will be driven to rotate, thereby driving the diffuser 415 to rotate. And when the first rotating rod 412 rotates, it will drive the reciprocating thread groove 413 to rotate, thereby driving the thread sleeve 414 to move up and down. By the up and down movement of the thread sleeve 414, the diffuser 415 will be driven to move up and down, so that the gas diffuses evenly from the center to the surrounding, initially breaking the laminar state and improving the diffusion efficiency. A connecting plate 418 is fixedly connected to the inner wall of the simulation chamber body 1. A vertical rod 419 movably penetrates through the inside of the connecting plate 418 and extends to the upper and lower sides of the connecting plate 418.

By the up and down movement of the fixing block 420, the connecting rods 421 will be driven to move up and down. When the connecting rods 421 move, the toothed plate 422 will be driven to move up and down. The up and down movement of the toothed plate 422 drives the gear 424 and the second rotating rod 423 inside it to rotate, thereby driving the first guide plates 425 to rotate.By continuously rotating the first deflector 425, the flow direction of the air flow can be guided, enabling the gas to be more evenly distributed throughout the simulation chamber body 1, thereby making the gas-dust distribution uniform and improving the accuracy of detection.

[0030] Working principle: When the simulation chamber body 1 for detecting occupational disease hazard factors is operating, the gas and dust to be measured are introduced into the simulation chamber body 1 through the conveying pipe 3. The gas control box 2 adjusts the gas flow rate and pressure to ensure stable gas input. After the gas is introduced through the conveying pipe 3, the motor 411 is started. The motor 411 drives the first rotating rod 412 to rotate. When the first rotating rod 412 rotates, it drives the turntable 416 to rotate. Through the rotation of the turntable 416, the telescopic rod 417 is driven to rotate, thereby driving the diffuser 415 to rotate. And when the first rotating rod 412 rotates, it drives the reciprocating wire groove 413 to rotate, thereby driving the wire sleeve 414 to move up and down. Through the up and down movement of the wire sleeve 414, the diffuser 415 is driven to move up and down, enabling the gas to uniformly diffuse from the center to the surroundings, initially breaking the laminar flow state and improving the diffusion efficiency. When the wire sleeve 414 moves up and down, it drives the vertical rod 419 to move up and down. The up and down movement of the vertical rod 419 drives the fixed block 420 to move up and down. Through the up and down movement of the fixed block 420, the connecting rod 421 is driven to move up and down. When the connecting rod 421 moves, it drives the toothed plate 422 to move up and down. The up and down movement of the toothed plate 422 drives the gear 424 and the second rotating rod 423 inside it to rotate, thereby driving the first deflector 425 to rotate. By continuously rotating the first deflector 425, the flow direction of the air flow can be guided, enabling the gas to be more evenly distributed throughout the simulation chamber body 1, thereby making the gas-dust distribution uniform and improving the accuracy of detection.

[0031] Please refer to Figure 1-8On the basis of the above-mentioned embodiment, in another embodiment of the present invention, an anti-sinking mechanism 5 is arranged inside the simulation cabin body 1, and the anti-sinking mechanism 5 comprises an elastic support rod 511, and the outer wall of the elastic support rod 511 is sleeved with a spring 512, and the top of the elastic support rod 511 is fixedly connected with a vibration plate 513, and the bottom of the vertical rod 419 is fixedly connected with a longitudinal plate 514, and the bottom of the longitudinal plate 514 is fixedly connected with two resistance rods 515. When the vertical rod 419 moves downward, it will drive the longitudinal plate 514 and the resistance rod 515 at the bottom to descend, and the resistance rod 515 will resist the vibration plate 513 up and down. The vibration plate 513 can be made to vibrate in the vertical direction, so that the dust deposited thereon can be raised again, and the dust can be prevented from settling, and the dust can be prevented from settling and causing data deviation. The dust can also be evenly distributed in the simulation cabin body 1, and the accuracy of the detection result can be further improved. The bottom of the inner wall of the simulation cabin body 1 is fixedly connected to a third rotating rod 516 through a bearing. The third rotating rod 516 movably penetrates the vibration plate 513 and extends upward. The outer wall of the third rotating rod 516 is provided with an arc groove 517. The top of the vibration plate 513 is fixedly connected to a fixing ring 518, and the inner wall of the fixing ring 518 is fixedly connected to a fixing rod 519. The arc groove 517 The third rotating rod 516 is sleeved on the outside of the fixing rod 519, and a circular groove is provided inside the fixing ring 518. The inside of the circular groove is slidably connected with an arc block 520. The top of the arc block 520 is fixedly connected with a horizontal plate 521. The bottom of the horizontal plate 521 is fixedly connected with a first brush 522. The outer wall of the third rotating rod 516 is fixedly connected with a first push rod 523. The top of the horizontal plate 521 is fixedly connected with a blocking rod 524. The first push rod 523 is in contact with the blocking rod 524. When the vibration plate 513 descends, the fixing ring 518 is driven to descend, and the descending of the fixing ring 518 drives the fixing rod 519 on its inner wall to descend. The fixing rod 519 is in The up and down movement of the inside of the arc groove 517 will cause the third rotating rod 516 to rotate. When the third rotating rod 516 rotates, it will drive the first push rod 523 to rotate. Under the resistance of the first push rod 523, it will push the blocking rod 524 to rotate. When the blocking rod 524 rotates, it will drive the bottom cross plate 521 to rotate, so that the arc block 520 slides in the circular groove inside the fixed ring 518. The rotation of the cross plate 521 drives the first brush 522 to rotate. The settled dust is re-raised through the mechanical stirring of the first brush 522, thereby improving the uniformity of the gas dust and thus improving the accuracy of detection.

[0032] Working principle: When the vertical rod 419 moves downward, it drives the longitudinal plate 514 and the contact rod 515 at its bottom to descend. Through the up-and-down contact action between the contact rod 515 and the vibrating plate 513, the vibrating plate 513 can vibrate in the vertical direction, causing the dust deposited on it to be re-suspended, preventing dust settlement, preventing data deviation caused by dust settlement, and also making the dust evenly distributed in the simulation chamber body 1, further improving the accuracy of the detection result. Moreover, when the vibrating plate 513 descends, it drives the fixing ring 518 to descend. The descent of the fixing ring 518 drives the fixing rod 519 on its inner wall to descend. The up-and-down movement of the fixing rod 519 inside the arc-shaped groove 517 causes the third rotating rod 516 to rotate. When the third rotating rod 516 rotates, it drives the first push rod 523 to rotate. Under the contact action of the first push rod 523, the stop rod 524 is pushed to rotate. When the stop rod 524 rotates, it drives the horizontal plate 521 at the bottom to rotate, so that the arc-shaped block 520 slides in the circular groove inside the fixing ring 518. By rotating the horizontal plate 521, the rotation of the first brush 522 is driven. Through the mechanical agitation of the first brush 522, the settled dust is re-suspended, thereby improving the uniformity of the gas and dust to enhance the accuracy of the detection.

[0033] Please refer to Figure 1-8 , on the basis of the above embodiment, in another embodiment of the present invention, a rotating mechanism 6 is provided inside the simulation chamber body 1. The rotating mechanism 6 includes a second push rod 611. The second push rod 611 is fixedly connected to the top of the horizontal plate 521. The top inner wall of the simulation chamber body 1 is rotatably connected by bearings to two fourth rotating rods 612. Curved guide plates 613 are respectively fixedly connected to the outer walls of the two fourth rotating rods 612. When the horizontal plate 521 rotates, it drives the second push rod 611 to rotate, thereby driving the stopper 615 to rotate through the rotation of the second push rod 611. When the stopper 615 rotates, it drives the fourth rotating rod 612 to rotate. Through the rotation of the fourth rotating rod 612, the curved guide plate 613 is driven to rotate. By rotating the curved guide plate 613, the problem of uneven distribution of gas and dust inside the simulation chamber body 1 can be solved, especially for some hard-to-reach corners or dead-end areas. Through the angle adjustment and air flow guidance of the curved guide plate 613, a more comprehensive and uniform diffusion effect is achieved. Torsion springs 614 are respectively arranged on the outer walls of the two fourth rotating rods 612. Stoppers 615 are respectively fixedly connected to the bottoms of the two fourth rotating rods 612. Second brushes 616 are respectively fixedly connected to the outer walls of the two fourth rotating rods 612. The second brushes 616 are in contact with the inner wall of the simulation chamber body 1. When the fourth rotating rod 612 rotates, it drives the second brush 616 to rotate. By scraping the inner wall of the dead end with the second brush 616, the distribution of gas and dust inside the simulation chamber body 1 can be made more uniform, avoiding data deviation caused by dust on the inner wall and improving the reliability of the detection result.

[0034] Working principle: When the cross plate 521 rotates, it will drive the second push rod 611 to rotate, thereby driving the stopper 615 to rotate through the rotation of the second push rod 611. When the stopper 615 rotates, it will drive the fourth rotating rod 612 to rotate. Through the rotation of the fourth rotating rod 612, the curved deflector 613 will be driven to rotate. By rotating the curved deflector 613, the problem of uneven distribution of gas and dust inside the simulation cabin body 1 can be solved. Especially for some inaccessible corners or dead areas, through the angle adjustment and air flow guidance of the curved deflector 613, a more comprehensive and uniform diffusion effect can be achieved. And when the fourth rotating rod 612 rotates, it will drive the second brush 616 to rotate. By scraping the inner wall of the dead corner with the second brush 616, the distribution of gas and dust inside the simulation cabin body 1 can be made more uniform, avoiding data deviation caused by dust on the inner wall and improving the reliability of the detection results.
