In the description of the present invention, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0031] like Figure 1-Figure 7 As shown, the present invention provides a construction engineering environment detection device, including a base 10 and a controller, the bottom of the base 10 has a plurality of casters 11, the above contents are all prior art, and the specific structure is not repeated here. The device also includes a side plate 20, a sampling tube 30, an upper sealing cover 31, a lower sealing cover 32, a first motor 40 and a rotating assembly 50.

[0032] The two side panels 20 are symmetrically arranged, and both side panels 20 are fixedly mounted on the top of the base 10 .

[0033] The sampling barrel 30 is disposed between the two side plates 20 in the longitudinal direction. The sampling barrel 30 is provided with a plurality of sampling holes 33 penetrating along the axial direction thereof. The plurality of sampling holes 33 are arranged in sequence at equal intervals along the circumference thereof.

[0034] The upper sealing cover 31 and the lower sealing cover 32 are respectively arranged above and below the sampling barrel 30, and are both rotatably connected to the sampling barrel 30. The upper sealing cover 31 and the lower sealing cover 32 are both fixedly connected to the two side plates 20, and are both sealed with the sampling barrel 30. The upper sealing cover 31 is provided with an upper notch 34 that penetrates in the longitudinal direction, and the upper notch 34 can only expose one sampling hole 33 at a time. The lower sealing plate is provided with a lower notch 35 that penetrates in the longitudinal direction, and the lower notch 35 corresponds to the upper notch 34.

[0035] The first motor 40 is fixedly mounted on the upper sealing cover 31 or the lower sealing cover 32 and is electrically connected to the controller. The first motor 40 is used to control the rotation of the sampling tube 30 .

[0036] The rotating assembly 50 includes a rotating shaft 51, a first support plate 52, a second support plate 53 and a second motor 54. The rotating shaft 51 is arranged in the longitudinal direction and is rotatably connected to the base 10. The first support plate 52 is fixedly installed on the rotating shaft 51 in the transverse direction and is adapted to the upper notch 34. A high-speed camera 55 is fixedly installed on the first support plate 52. The lens of the high-speed camera 55 passes through the first support plate 52 and faces vertically downward. A first sealing ring 551 is fixedly installed at the lens of the high-speed camera 55. The second support plate 53 is fixedly installed on the rotating shaft 51 in the transverse direction and is adapted to the lower notch 35. The second support plate 53 is located directly below the first support plate 52. A projection plate 56 is fixedly installed on the second support plate 53. A second sealing ring 561 is arranged on the outer side of the projection plate 56. The second sealing ring 561 is fixedly connected to the second support plate 53. The second motor 54 is fixedly installed on the base 10 and is electrically connected to the controller. The second motor 54 is used to control the rotation of the rotating shaft 51.

[0037] In the initial state, one of the sampling holes 33 is located in the upper notch 34. At this time, the first sealing ring 551 contacts the upper end surface of the sampling tube 30, and the second sealing ring 561 contacts the lower end surface of the sampling tube 30. Therefore, dust particles in the outside air will not contaminate the lens of the high-speed camera 55 and the projection board 56.

[0038] The specific working process of this equipment is:

[0039] First, the staff moves the device to the construction project to be inspected and leaves it for more than twenty minutes. At this time, the sampling holes 33 located at the upper notch 34 and the lower notch 35 will be filled with the air in the environment, and the dust particle content in the air in the sampling holes 33 is very close to the dust particle content in the air in the environment.

[0040] Then, the staff sends instructions to the controller through a wireless device such as a remote control. The controller controls the second motor 54 to start, and the second motor 54 drives the rotating shaft 51 to rotate slowly, minimizing the disturbance to the surrounding air, until the first sealing ring 551 and the second sealing ring 561 are aligned with the sampling hole 33. At this time, the high-speed camera 55 and the projection plate 56 are aligned with the sampling hole 33.

[0041] Next, the controller controls the lens of the high-speed camera 55 to aim at the projection board 56 for flash photography, exposing the dust particles in the air in the sampling hole 33 to the projection board 56, and counting the number of dust particles in the air through the photos taken by the high-speed camera 55 to determine the ambient air quality, and finally the device can be taken away.

[0042] It is worth noting that after taking away the device, the staff can control the first motor 40 to rotate, and the first motor 40 drives the sampling tube 30 to rotate until the next clean sampling hole 33 moves to the upper notch 34 and the lower notch 35. Then the second motor 54 is controlled to rotate, and the second motor 54 drives the rotating shaft 51 to rotate until the first sealing ring 551 contacts the upper end surface of the sampling tube 30, and the second sealing ring 561 contacts the lower end surface of the sampling tube 30, and the device returns to the initial state. The staff can immediately move the device to the next construction project environment to continue testing.

[0043] In this device, the high-speed camera 55 and the projection plate 56 in the rotating assembly 50 cooperate with the different sampling holes 33 on the sampling tube 30 to sample and test the air in different construction engineering environments. Compared with traditional testing equipment that needs to be cleaned after testing before the next test, the testing efficiency of this device is higher. In addition, this device does not use an exhaust fan when collecting air samples, so the disturbance to the surrounding air is small, so the sampled air sample is more accurate and the detection accuracy is also higher.

[0044] In one embodiment, the rotating assembly 50 further includes a third support plate 57 and an air pump 58. The third support plate 57 is fixedly mounted on the rotating shaft 51 in the transverse direction and is adapted to the upper notch 34. The air pump 58 is fixedly mounted on the third support plate 57 and is electrically connected to the controller, and an air outlet of the air pump 58 passes through the third support plate 57 and extends downward.

[0045] The specific cleaning process of the sampling hole 33 is as follows: the controller controls the rotating shaft 51 to rotate until the air outlet of the air pump 58 is aligned with the sampling hole 33. Then the controller controls the air pump 58 to start, and the air pump 58 sprays high-pressure gas to blow out all the dust particles attached to the inner wall of the sampling hole 33.

[0046] It is worth noting that if the detection tasks are small and not urgent, the staff can clean the sampling holes 33 immediately after the detection is completed. If the detection tasks are large and urgent, the staff can clean each sampling hole 33 in turn after all the sampling holes 33 are used.

[0047] In one embodiment, a cleaning assembly 60 is further included, and the cleaning assembly 60 includes a first fixing plate 61 and a second fixing plate 62. The first fixing plate 61 and the second fixing plate 62 are both fixedly mounted on one of the side plates 20, and a first sponge pad 63 is fixedly mounted on the first fixing plate 61, and the first sponge pad 63 can contact the lens of the high-speed camera 55. A second sponge pad 64 is fixedly mounted on the second fixing plate 62, and the second sponge pad 64 can contact the projection plate 56.

[0048] When the controller controls the rotation of the rotating shaft 51, the lens of the high-speed camera 55 will contact the first sponge pad 63, and the projection plate 56 will contact the second sponge pad 64, so that the lens of the high-speed camera 55 and the projection plate 56 are wiped respectively to avoid contamination of the lens of the high-speed camera 55 and the projection plate 56 by dust particles in the previous detection process, thereby further improving the detection accuracy of the device.

[0049] In one embodiment, a first guide surface 631 is formed on the first sponge pad 63, and the first guide surface 631 can contact the lens of the high-speed camera 55. A second guide surface 641 is formed on the second sponge pad 64, and the second guide surface 641 can contact the projection plate 56.

[0050] The design of the first guide surface 631 can make the contact between the lens of the high-speed camera 55 and the first sponge pad 63 smoother, and the wiping effect on the lens of the high-speed camera 55 is better. The design of the second guide surface 641 can make the contact between the projection board 56 and the second sponge pad 64 smoother, and the wiping effect on the projection board 56 is better.

[0051] In one embodiment, the upper notch 34 and the lower notch 35 are arc-shaped notches. The first support plate 52, the second support plate 53 and the third support plate 57 are all formed with arc-shaped surfaces adapted to the arc-shaped notches. In this way, the operation of the device will be smoother and the interference between the above-mentioned components will be reduced.

[0052] In one embodiment, an upper annular sealing groove 36 and a lower annular sealing groove are respectively formed on the upper end surface and the lower end surface of the sampling tube 30 .

[0053] An upper arc-shaped sealing strip 37 is fixedly installed at the bottom of the upper sealing cover 31, and the upper arc-shaped sealing strip 37 is adapted to the upper annular sealing groove 36 to improve the sealing effect and prevent external dust particles from passing through the gap between the upper sealing cover 31 and the sampling barrel 30 to pollute the unused sampling holes 33. A lower arc-shaped sealing strip is fixedly installed at the bottom of the lower sealing cover 32, and the lower arc-shaped sealing strip is adapted to the lower annular sealing groove to improve the sealing effect and prevent external dust particles from passing through the gap between the lower sealing cover 32 and the sampling barrel 30 to pollute the unused sampling holes 33.

[0054] In one embodiment, the number of sampling holes 33 is six.
