[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 7 A building material volatility detection device includes a safety helmet 1, which includes a hat 11, a fixing rope 12 and a bottom plate 13. The bottom plate 13 is arranged on the hat 11 and separates the hat 11 into an upper part and a lower part. The fixing rope 12 is arranged on the hat 11. A detection board 2, a detection device 3, a driving device 4 and an air pumping device 5 are arranged on the bottom plate 13. A power supply is arranged on the detection board 2, and its two ends are respectively arranged on the hat 11 and the fixing rope 12. When an operator wears the safety helmet 1 correctly on his head, the hat 11 contacts the top of the operator's head, and the fixing rope 12 is hooked on the operator's chin, so that the human body becomes a conductor, and the positive and negative poles of the single power supply are connected, thereby supplying power to the detection board 2.

[0026] Only when the operator wears the safety helmet correctly can the detection board 2 be powered on and the detection operation be performed, thereby forcing the operator to wear the safety helmet before entering the construction site to perform radioactive substance detection on building materials.

[0027] The driving device 4 includes a guide sleeve 41, a sliding block 42, a first elastic member 43 and a second elastic member 44. The guide sleeve 41 is arranged on the bottom plate 13 and is provided with a longitudinal slide slot hole 411. The sliding block 42 is arranged in the slide slot hole 411 for guiding and sliding, and a gravity ball 422 is arranged in the middle. The first elastic member 43 and the second elastic member 44 are both arranged in the guide sleeve 41, and the two ends of the first elastic member 43 are respectively in contact with the upper end surface of the sliding block 42 and the top surface of the inner hole of the guide sleeve 41, and the two ends of the second elastic member 44 are respectively in contact with the lower end surface of the sliding block 42 and the bottom surface of the inner hole of the guide sleeve 41.

[0028] After the operator wears the safety helmet 1 correctly, when walking, the person's head will move up and down, thereby driving the safety helmet 1 to move up and down together, and the sliding block 42 remains in the original position due to the effect of inertia. After the action of the elastic member, it returns to the middle position. When the person walks, the person moves up and down, so at this time the sliding block 42 also slides up and down relative to the guide sleeve 41.

[0029] The sliding block 42 is extended outward through the slide slot hole 411, and a horizontal slide slot hole 421 is provided on the plate extended outward, and the pumping device 5 includes an impeller 51 and an outer cover 52, the outer cover 52 is arranged on the bottom plate 13, the impeller 51 is unidirectionally rotatably arranged on the outer cover 52, and an air inlet 521, a first air outlet 522 and a second air outlet 523 are arranged on the outer cover 52, wherein the impeller 51 rotates to inhale air from the air inlet 521 and press it out from the first air outlet 522 and the second air outlet 523, a turntable 511 is arranged on one end of the impeller 51, a crank handle 512 is arranged at the edge of the turntable 511, and it is slidably and rotatably arranged on the horizontal slide slot hole 421 of the sliding block 42.

[0030] The sliding block 42 slides downward, driving the crank handle 512 to move downward together, and the crank handle 512 is arranged on the turntable 511, and its downward movement drives the turntable 511 to rotate. The rotation of the turntable 511 drives the crank handle 512 to move in the horizontal direction, so that it slides in the horizontal slide slot hole 421. When the crank handle 512 reaches the bottom, the limiting sliding block 42 prevents it from sliding downward. When the sliding block 42 slides upward relative to the guide sleeve 41, it drives the crank handle 512 to move upward together, thereby causing the turntable 511 to rotate, and then continuous movement causes the rotating 511 to rotate. The impeller 51 is unidirectionally arranged on the outer cover 52, so the impeller 51 rotates in one direction. Therefore, when it is at the highest point or the lowest point, it does not rotate back, thereby driving the impeller 51 to rotate continuously, thereby sucking air from the air inlet 521 and discharging it from the first air outlet 522 and the second air outlet 523.

[0031] The detection device 3 includes an air cylinder 31, a piston ring 32 and a piston rod 33. The air cylinder 31 is arranged on the base plate 13, and is provided with a front air inlet 311, a rear air inlet 312, a front air outlet 313 and a rear air outlet 314. The rear air inlet 312 is connected to the second air outlet 523 through a hose, and the first air outlet 522 is connected to the front air inlet 311 through a hose. The detection plate 2 is arranged on the piston ring 32, and the piston ring 32 is slidably arranged in the air cylinder 31. The piston rod 33 is arranged on the piston ring 32, and is slidably arranged on one end of the air cylinder 31. The positive and negative poles of the power supply on the detection plate 2 are connected to the outside through the piston rod 33, and the air cylinder 31 is arranged on the safety helmet 1.

[0032] An air intake switch device 34 is arranged on the first air outlet 522 and the second air outlet 523, and a first slide 341 and a second slide 342 are arranged thereon, the first slide 341 has a long slot hole in the lower half, the second slide 342 has a long slot hole in the upper half, and the air intake switch device 34 is arranged on the sliding block 42, and an air outlet switch device 35 is slidably arranged on the front air outlet 313 and the rear air outlet 314, and a third slide 351 and a fourth slide 352 are respectively arranged thereon, the fourth slide 352 has a long slot hole in the lower half, the third slide 351 has a long slot hole in the upper half, and the air outlet switch device 35 is arranged on the sliding block 42.

[0033] In the initial state, the sliding block 42 is located in the middle position of the guide sleeve 41, and the air inlet switch device 34 and the air outlet switch device 35 are both in the closed state. When the sliding block 42 starts to slide up and down, it drives the impeller 51 to rotate, thereby sucking air from the outside and discharging it from the first air outlet 522 and the second air outlet 523. When the sliding block 42 is located in the upper half of the guide sleeve 41, it drives the air inlet switch device 34 and the air outlet switch device 35 to be located above the initial position. Therefore, the long slot hole on the first sliding plate 341 is aligned with the first air outlet 522, so that air can enter the air cylinder 31 from the front air inlet 311 through the hose, and at this time, the flat plate part of the second sliding plate 342 is aligned with the second air outlet 523, so that the second air outlet 523 is blocked.

[0034] The air outlet switch device 35 also follows the sliding block 42 and is located above the initial position. At this time, the long slot hole on the fourth sliding plate 352 on the rear air outlet 314 is aligned with the rear air outlet 314, so that the air is discharged from this port, and the flat plate on the third sliding plate 351 on the front air outlet 313 is aligned with the front air outlet 313, so that the front air outlet 313 is in a closed state.

[0035] Therefore, at this time, the air enters the air cylinder 31 from the front air inlet 311 through the hose. At this time, the front end of the air cylinder 31 is in a sealed state, so that after the air enters, it pushes the piston ring 32 to move backward, and the air at the rear end of the piston ring 32 is discharged from the rear end air outlet 314. The detection plate 2 is located on the front end surface of the piston ring, so the incoming air is detected to obtain a detection value.

[0036] When the sliding block 42 slides downward and is located at the lower half of the guide sleeve 41, the air inlet switch device 34 and the air outlet switch device 35 are driven to be located below the initial position, so that the flat plate on the first sliding plate 341 is aligned with the first air outlet 522, so that the first air outlet 522 is blocked, and the long slot hole of the second sliding plate 342 is aligned with the second air outlet 523, so that the air enters the air cylinder 31 from the second air outlet 523 through the hose from the rear end air inlet 312, and the flat plate on the fourth sliding plate 352 on the rear end air outlet 314 is aligned with the rear end air outlet 314, so that this air outlet is blocked, and the long slot hole on the third sliding plate 351 on the front end air outlet 313 is aligned with the front end air outlet 313, so that the air can be discharged from this hole.

[0037] Therefore, at this time, the air enters the air cylinder 31 from the rear end air outlet 314 through the hose. At this time, the rear end of the air cylinder 31 is in a sealed state. After the air enters, it pushes the piston ring 32 to move forward, and the air at the front end of the piston ring 32 is discharged from the front end air outlet 313, so that all the detected air is discharged from the air cylinder 31, so that the air detected next time is brand new air.

[0038] Its working principle or usage is as follows:

[0039] After the operator wears the helmet correctly, the human body becomes a conductor, and the power supply on the detection board 2 is connected, so that the detection board 2 is powered on, and then the detection operation can be carried out. When the operator enters the space that needs to be detected, the start switch is pressed to start the detection board 2 to start working.

[0040] At this time, the operator starts to walk around in the detection space. At the start and stop of each step of the operation, the person's head will first rise to the highest point and then drop to the initial position. The person's head can move up and down once at each step, thereby driving the safety helmet 1 to move up and down together. The sliding block 42 will remain in the original position for a certain period of time due to inertia, and then move together under the action of the elastic member. When the movement direction changes, the sliding block 42 will move in the original movement direction for a certain period of time due to inertia, and then move together under the action of the elastic member. Therefore, relatively, with the guide sleeve 41 as a reference, the sliding block 42 slides up and down and reciprocates with the guide sleeve 41.

[0041] When the sliding block 42 slides downward, it drives the crank 512 to move downward together. The crank 512 is set on the turntable 511, and its downward movement drives the turntable 511 to rotate. The rotation of the turntable 511 drives the crank 512 to move in the horizontal direction, so that it slides in the horizontal slide slot hole 421. When the crank 512 reaches the bottom, the sliding block 42 is limited so that it no longer slides downward. When the sliding block 42 slides upward relative to the guide sleeve 41, it drives the crank 512 to move upward together, so that the turntable 511 rotates, and then the continuous movement makes the rotating 511 rotate, thereby driving the impeller 51 to rotate, so that air is sucked in from the air inlet 521 and discharged from the first air outlet 522 and the second air outlet 523.

[0042] When the sliding block 42 is located at the upper half of the guide sleeve 41, it drives the air inlet switch device 34 and the air outlet switch device 35 to be located above the initial position, so that the long slot hole on the first sliding plate 341 is aligned with the first air outlet 522, so that air can enter the air cylinder 31 from the front air inlet 311 through the hose, and at this time, the flat plate part of the second sliding plate 342 is aligned with the second air outlet 523, so that the second air outlet 523 is blocked, and the air outlet switch device 35 also follows the sliding block 42 and is located below the initial position. At this time, the long slot hole on the fourth sliding plate 352 on the rear air outlet 314 is aligned with the rear air outlet 314, so that air is discharged from this port, and the flat plate on the third sliding plate 351 on the front air outlet 313 is aligned with the front air outlet 313, so that the front air outlet 313 is in a closed state.

[0043] Therefore, at this time, the air enters the air cylinder 31 from the front air inlet 311 through the hose. At this time, the front end of the air cylinder 31 is in a sealed state, so that after the air enters, it pushes the piston ring 32 to move backward, and the air at the rear end of the piston ring 32 is discharged from the rear end air outlet 314. The detection plate 2 is located on the front end surface of the piston ring, so the incoming air is detected to obtain a detection value.

[0044] When the sliding block 42 slides downward and is located at the lower half of the guide sleeve 41, the air inlet switch device 34 and the air outlet switch device 35 are driven to be located below the initial position, so that the flat plate on the first sliding plate 341 is aligned with the first air outlet 522, so that the first air outlet 522 is blocked, and the long slot hole of the second sliding plate 342 is aligned with the second air outlet 523, so that the air enters the air cylinder 31 from the second air outlet 523 through the hose from the rear end air inlet 312, and the flat plate on the fourth sliding plate 352 on the rear end air outlet 314 is aligned with the rear end air outlet 314, so that this air outlet is blocked, and the long slot hole on the third sliding plate 351 on the front end air outlet 313 is aligned with the front end air outlet 313, so that the air can be discharged from this hole.

[0045] Therefore, at this time, the air enters the air cylinder 31 from the rear end air outlet 314 through the hose. At this time, the rear end of the air cylinder 31 is in a sealed state. After the air enters, it pushes the piston ring 32 to move forward, and the air at the front end of the piston ring 32 is discharged from the front end air outlet 313, so that all the detected air is discharged from the air cylinder 31, so that the air detected next time is brand new air.

[0046] This cycle repeats itself, with each step the operator takes, the air is sampled once, and the measurement position changes due to the person walking, so each measurement is of new air at the new position.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
