Description

Technical Field

[0001] The present invention relates to the technical field of air quality monitoring equipment, and more specifically, to a satellite remote sensing gas quality monitoring device. Background Art

[0002] During the construction process of a construction site, there will be a large amount of dust, which affects the air quality. In order to ensure air quality, it is necessary to monitor the air in the construction site to facilitate sprinkling water into the construction site at any time, thereby reducing dust. An air detector can be used to monitor the air quality of the construction site. The air detector can detect the dust in the air through the principle of light scattering and transmit signals through satellites to remotely send the results detected by the air detector to the user's smartphone, enabling remote monitoring of air quality.

[0003] In the prior art, generally, the air detector is directly installed outside the construction site, and the air quality is detected by the detection light emitted by the air detector. However, when it is in use, there are some problems. The air detector is outdoors and is easily damaged by wind, sun and rain under natural conditions. However, it is not obvious from the outside whether it is damaged. Using a damaged air detector to monitor air quality will affect the accuracy of air detection. Moreover, due to different weather conditions, the external brightness is different, which will have a certain impact on the air quality detector, resulting in deviations in the detection results when detecting air quality.

One end of the two first reset springs 27 extends to the first outlet end 6 and the second outlet end 7, respectively.

[0033] The water changing mechanism includes a water outlet pipe 28 fixedly installed on one side of the lower surface of the purification tank 1. A first twisting valve 29 is installed at the outlet end of the water outlet pipe 28. The outlet end of the first twisting valve 29 is connected to a drain pipe 30.

One side of the lower surface of the purification tank 1 is installed with a first guiding slideway 36. A first guiding block 37 is provided below the purification tank 1. The upper end of the first guiding block 37 is located within the first guiding slideway 36. The lower surface of the first guiding block 37 is an inclined surface. One side surface of the first guiding block 37 is installed with a spring ejector pin 38. The other side surface of the first guiding block 37 is installed with a driving wheel 39. One side of the lower end of the lifting column 31 is installed with a triangular prism 40. One side surface of the upper end of the purification tank 1 is installed with a water inlet pipe 41. The water inlet pipe 41 is connected to a second twisting valve 42. The inlet end of the second twisting valve 42 is connected to the tap water pipe. The twisting end of the second twisting valve 42 is installed with a third return spring 43. The upper end of the second twisting valve 42 is installed with a fixing plate 44. The upper end of the third return spring 43 is fixedly connected to the lower surface of the fixing plate 44. One side of the third return spring 43 is installed with a supporting wheel 45. One side of the lifting column 31 is installed with an L-shaped moving rod 46. The upper end of the L-shaped moving rod 46 is installed with an inclined platform 47. Through the conversion of the outlet end of the three-way valve 4, normal air and purified air can be respectively introduced into the monitoring box 9, which is convenient for self-checking the air quality detector 10 and ensuring the detection result.

[0034] The shutter mechanism includes a fixed block 48 fixedly installed at the upper end of the exhaust pipe 20. One side of the fixed block 48 is connected with a rotating plate 49 through a hinge. A connecting plate 50 is installed at the lower end of the exhaust pipe 20. One side of the connecting plate 50 is installed with a fourth return spring 51. One end of the fourth return spring 51 is fixedly connected to the lower end of the rotating plate 49. Through the fourth return spring 51, the rotating plate 49 can be pulled towards the outlet end of the exhaust pipe 20, thereby closing the exhaust port 20 and preventing air from entering the monitoring box 9 when this device is not in use.

[0035] The support mechanism includes support legs 52 fixedly installed at the four corners of the lower surface of the purification tank 1. Both sides of the lower end of the support legs 52 are installed with support plates 53. A plurality of round holes 54 are opened on the support plates 53. Passing bolts through the round holes can facilitate the installation of this device.

[0036] The guiding mechanism includes a plurality of guiding rods 55 fixedly installed on one side surface of the purification tank 1. One end of the guiding rods 55 is installed with guiding wheels 56. Guiding grooves 57 are opened on both side surfaces of the lifting column 31. One end of the guiding wheels 56 is located within the guiding grooves 57, which can ensure the moving direction of the guiding rods 55.

[0037] The inspection mechanism includes an inspection window 58 located on the monitoring box 9. A transparent protective glass 59 is installed at the inspection window 58. Second guiding chutes 60 are installed on both sides of the transparent protective glass 59. A stop block 61 is installed at the lower end of the second guiding chutes 60. A protective plate 62 is provided on one side of the monitoring box 9. Both ends of the protective plate 62 are located within the second guiding chutes 60. A connecting handle 63 is installed at the upper end of the protective plate 62. By pulling the protective plate 62 upward, the internal condition of the monitoring box 9 can be observed through the transparent protective glass 59. When using this device, the transparent protective glass 59 is blocked by the protective plate 62, which can reduce the influence of external brightness on the detection result during the use of this device.

[0038] A square through-hole 64 is opened at the upper end of the purification box 1. A protective box 65 is installed at the lower end of the square through-hole 64. The square through-hole 64 is located below the lifting rod 23, which facilitates the lifting of the lifting rod 23.

[0039] A plurality of warning lights 66 are installed at the upper end of the monitoring box 9. When this device is damaged or the air quality is too poor, the warning lights 66 can be lit for reminder.

[0040] A liquid level sensor 67 is installed inside the purification box 1, and an optical turbidity meter 68 is installed on the upper surface inside the purification box 1, which can facilitate the detection of the water quality inside the purification box 1, so as to change the water.

[0041] In this implementation scheme, the electrical equipment of this device is controlled by an external controller, and the detection signal is transmitted through a satellite. This device can be remotely controlled and the detection result can be viewed. When in use, this device is moved to one side of the construction site. A hole is opened on the ground and expansion screws are installed. The lower end of the bolt is passed through the round hole 54 and screwed into the expansion screw, so that this device is installed through the support plate 53 and the support legs 52. The outlet end of the drain pipe 30 is placed on one side of the concrete mixer inside the construction site. The outlet end of the water supply pipe is connected to the inlet end of the second turning valve 42. The staff opens the second turning valve 42 to add an appropriate amount of water into the purification box 1, and makes the water surface above the outlet end of the second air inlet pipe 14. When the water surface reaches, the second turning valve 42 is released. Under the elastic force of the third return spring 43, the turning end of the second turning valve 42 is closed, thus stopping the water inlet.

[0042] After the power is turned on, the twist handle 5 on the three-way valve 4 is placed on the side of the first outlet end 6, and the toggle platform 24 at the lower end of the lifting rod 23 is used to support it to prevent it from falling back, thereby opening the first outlet end 6, starting the exhaust fan 3, extracting air, and letting it enter the monitoring box 9 through the first outlet end 6, the first air inlet pipe 12, and the first air inlet 11 on the three-way valve 4. The circulating air is continuously tested by the air quality detector 10, so that the air quality in this construction site can be monitored, and the test results can be transmitted to the user's smart phone in real time via satellite, so that the results can be known at any time. If the air quality is poor, the warning light 66 on one side of the monitoring box 9 will be turned on as a reminder. When monitoring the air, under the action of gravity, The protective plate 62 moves downward in the second guide slide 60 and falls on the stopper 61, thereby blocking the transparent protective glass 59 and reducing the influence of the brightness of the external environment on the detection result. When it is necessary to check the situation inside the monitoring box 9, the protective plate 62 is pulled upward using the connecting handle 63 to check through the transparent protective glass 59. The air entering the monitoring box 9 will be discharged through the exhaust pipe 20. The air will open the rotating plate 49 at the outlet end of the exhaust pipe 20, so that the rotating plate 49 rotates upward around the hinge to open, discharge the air, and stretch the fourth return spring 51. When this device is not used, under the action of the fourth return spring 51 and gravity, the rotating plate 49 will close the outlet end of the exhaust pipe 20 to prevent outside air from entering.

[0043] After using it for a period of time, in order to prevent the air quality detector 10 from being damaged and resulting in inaccurate detection results, it is necessary to detect the air quality detector 10. Turn off the exhaust fan 3, start the electric telescopic rod 22 to shorten, and drive the lifting platform 21 to descend. The lifting platform 22 is below the lifting plate 32. When the lifting platform 22 descends, the lifting plate 32 lands on the support platform 33 and does not move. When the lifting platform 21 moves downward, it will drive the lifting rod 23 to move downward into the protection box 65, and cause the two toggle platforms 24 to move downward. When the toggle platform 24 moves, by rotating the pulley 25 on one side of the twisting handle 5, the friction between the toggle platform 24 and the twisting handle 5 can be reduced. When the position between the two toggle platforms 24 moves to one side of the twisting handle 5, under the elastic force of the first return spring 27, one end of the twisting handle 5 is pushed into the space between the two toggle platforms 24. The toggle platform 24 descends as the lifting rod 23 descends, and pushes the twisting handle 5 downward, causing the first outlet end 6 to close and the second outlet end 7 to open, and the twisting handle 5 moves to one side of the lower first return spring 27 and compresses the lower first return spring 27. The twisting handle 5 rotates to one side of the upper toggle platform 24. Start the exhaust fan 3, draw air through the second outlet end 7 and the second intake pipe 14 to the lower part of the water surface in the purification box 1. Separate the soot in the air through water, so that the air moves to the upper end of the purification box 1, and enters the monitoring box 9 through the third intake pipe 18 and the second intake port 13. The one-way valve 19 allows air to enter the monitoring box 9 and prevents air from flowing back. When air flows into the monitoring box 9, the original air in the monitoring box 9 is discharged through the exhaust pipe 20, so that the air inside the monitoring box 9 is all purified air, and the air quality detector 10 detects the air. If the result is normal, it means that the air quality detector 10 is in a normal state. Start the electric telescopic rod 22 to extend, and drive the twisting handle 5 to rotate to close the second outlet end 7 and open the first outlet end 6 to continue monitoring the air. If the result is abnormal, it means that the air quality detector 10 has been damaged, and the warning light 66 on the other side of the monitoring box 9 lights up to remind the nearby staff to deal with it.

[0044] After the device has been used for a period of time, the water in the purification box 1 becomes turbid. The photoelectric turbidity meter 68 is used to detect the water quality in the purification box. When the water quality is poor, the electric telescopic rod 22 is started to rise, first driving the lifting platform 21, the lifting rod 23 and the toggle platform 24 to move upward, and the twist handle 5 is rotated to the side of the first outlet end 6, the first return spring 27 above is compressed, and one end of the twist handle 5 is located on the side of the toggle platform 24 below. As the lifting platform 21 continues to rise, the lifting platform 21 pushes the lifting plate 32 upward and pulls the lifting column 31 to move upward. The lifting column 31 has guide grooves 57 on both sides. The guide wheel 56 on one side of the guide rod 55 can ensure the moving direction of the lifting column 31 and reduce the friction force when the lifting column 31 rises. When the lifting column 31 rises, the triangular prism 40 at the lower end of the lifting column 31 moves upward and contacts the pushing wheel 39 on one side of the first guide block 37. The thrust of the inclined surface of the triangular prism 40 on the pushing wheel 39 can push the first guide block 37 to one side in the first guide slide 36 to compress the spring ejector pin 38. The lower surface of the first guide block 37 is an inclined surface. When the first guide block 37 moves, the fixed wheel 35 on the twisting end of the first twist valve 29 can be pushed downward. The rotation of the wheel 35 can reduce the friction force, open the first twist valve 29, close the electric telescopic rod 22, so that the water in the purification box 1 is discharged to the side of the concrete mixer through the outlet pipe 28, the first twist valve 29, and the drain pipe 30, so that the water resources are recycled. When the water in the purification box 1 is discharged, negative pressure is generated, and the outside air enters the purification box 1 through the connecting port 13. The dust in the air is intercepted by the filter 15 to ensure the cleanliness of the air inside the purification box 1. When the second outlet port 7 is opened for air detection, when air is drawn into the purification box 1, part of the air enters the monitoring box 9, and the other part of the air passes through the connecting port 13. The interface 13 is discharged, and the dust above the filter 15 is blown away to prevent clogging. The water level inside the purification box 1 is detected by the liquid level sensor 67. When there is no water in the purification box 1, the electric telescopic rod 22 is started to continue to extend, so that the lifting column 31 continues to rise, and the inclined surface of the upper end of the triangular prism 40 passes through the driving wheel 39, and the inclined surface of the lower end of the triangular prism 40 begins to pass through the driving wheel 39. When the lifting column 31 continues to rise, the first guide block 37 returns to its original position under the elastic force of the spring ejector 38, and the torsional end of the first twist valve 29 returns to its original position under the elastic force of the second return spring 34, and the first twist valve 29 is closed.

[0045] The lifting column 31 continues to rise, driving the L-shaped moving rod 46 and the inclined platform 47 to move upward. The upper end of the inclined platform 47 contacts the support wheel 45 at the twisting end of the second twisting valve 42. Under the action of the inclined plane, when the inclined platform 47 moves, a thrust can be given to the support wheel 45, pushing the support wheel 45 upward and opening the second twisting valve 42. The electric telescopic rod 22 is closed, compressing the third return spring 43. After the water pipe is connected, water is added to the purification tank 1 through the second twisting valve 42 and the water inlet pipe 41. The water level is detected by the liquid level sensor 67. When the specified depth is reached, the electric telescopic rod 22 is started to shorten, driving the lifting platform 21 to move downward. Under the action of gravity, the lifting column 31 moves downward, causing the inclined platform 47 to leave the support wheel 45. The twisting end of the second twisting valve 42 returns to its original position under the elastic force of the third return spring 43 and closes the second twisting valve 42. As the electric telescopic rod 22 shortens, the lifting column 31 returns to its original position under the action of gravity and supports the lifting plate 32 through the support platform 33 to prevent it from falling further. When the lifting column 31 returns to its original position, the first twisting valve 29 can be opened and closed once by the triangular prism 40. At this time, the water surface in the purification tank 1 is still higher than the outlet end of the second air inlet pipe 14. After the water change is completed, this device can continuously monitor the air quality in the construction site.

[0046] The above technical solution only reflects the preferred technical solution of the technical solution of the present invention. Some changes that may be made by those skilled in the art to some parts thereof all reflect the principle of the present invention and fall within the protection scope of the present invention.
