[0002] The beta-ray dust detection device is a high-precision instrument for environmental air quality monitoring, and its core principle is based on the beta-ray attenuation method. When the device is running, it extracts ambient air through a sampling pump, causing particulate matter (such as PM10 or PM2.5) to deposit on the filter tape. Subsequently, a beam of low-energy beta rays (usually from a safe radioactive source such as carbon-14) penetrates the filter tape, and the increased mass of particulate matter causes the intensity of the rays to attenuate, allowing the particulate matter mass concentration in unit volume of air (such as μg / m³) to be accurately calculated by measuring the degree of attenuation.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0024] Please refer to Figures 1-6 The present application provides the following technical solutions: A construction environment monitoring device includes: a housing 1, with a door 2 installed at the opening on the front side of the housing 1; a filter belt conveying mechanism 3, which is installed in the middle of the interior of the housing 1 and is used to rotate and convey the filter belt 10; the filter belt conveying mechanism 3 can install two or more rolls of filter belt 10, and according to the existing equipment housing size, it can usually install 6-8 rolls of filter belt 10, which facilitates improving the working time after a single maintenance of the equipment.

[0025] The filter belt conveying mechanism 3 includes a driven shaft 31, a driven shaft 32, and a conveying motor 33. The driven shaft 31 and the driven shaft 32 are rotatably connected to the inside of the housing 1 on both sides. An inner stop plate 34 and an outer stop plate 35 are connected to both the driven shaft 31 and the driven shaft 32. The inner stop plate 34 and the outer stop plate 35 are used to limit and fix the filter belt 10. The housing 1 is equipped with a conveying motor 33 for driving the driven shaft 32 to rotate. A guide roller 36 is provided on the upper side of the driven shaft 31 and the driven shaft 32. The guide roller 36 is used to guide the filter belt 10 so that the filter belt 10 passes between the air intake assembly 5 and the air intake support assembly 6.

[0026] A filter belt switching mechanism 4 is installed on the inner wall of the housing 1. The filter belt switching mechanism 4 is equipped with an air intake component 5 and an air intake support component 6, and is used to switch the working positions of the air intake component 5 and the air intake support component 6 to realize the switching of the filter belt 10. The filter belt switching mechanism 4 switches the positions of the air intake component 5 and the air intake support component 6 by rotation. Its arc-shaped switching trajectory covers all the conveying areas of the filter belt 10, realizing the switching of all filter belts 10, and saving more space compared with the linear movement switching method.

[0027] The filter belt switching mechanism 4 includes a mounting bracket 41, a switching shaft 42, and a switching frame 43. The mounting bracket 41 is fixedly connected to the inner wall of the housing 1. The switching shaft 42 is vertically rotatably connected to the mounting bracket 41. The switching frame 43 is keyed to the switching shaft 42. A switching motor 44 is installed at the bottom of the mounting bracket 41, which drives the switching shaft 42 to rotate. The switching frame 43 is designed with a "U" shape to facilitate the installation of the air intake assembly 5 and the air intake support assembly 6.

[0028] A brush 11 is installed on the upper crossbeam of the switching frame 43. During the switching process, the switching frame 43 can drive the brush 11 to move and clean the surface of the filter belt 10 to be used, so as to avoid the dust on the surface of the filter belt 10 from affecting the test results.

[0029] The air intake assembly 5 is installed on the upper side of the filter belt switching mechanism 4 and is used to press the upper end face of the filter belt 10. The air intake support assembly 6 is installed on the lower side of the filter belt switching mechanism 4 and is used to support the lower end face of the filter belt 10 and provide power for ambient air collection.

[0030] The air intake assembly 5 includes an air intake seat 51 and an air intake pressure head 52. The air intake seat 51 is mounted on the upper crossbeam of the switching frame 43. The lower end of the air intake seat 51 is slidably connected to the air intake pressure head 52. The air intake pressure head 52 is used to press the upper end face of the filter belt 10, allowing the collected air to pass through the filter belt 10. The air intake pressure head 52 can move up and down under the drive of the drive structure to press and release the filter belt 10, facilitating the transport of the filter belt 10. A partition 8 is installed on the upper side of the air pump 62. The partition 8 reduces the impact of the vibration of the air pump 62 during operation on the detection space above the housing 1.

[0031] An air inlet pipe 9 is installed on the top of the housing 1. The lower end of the air inlet pipe 9 is connected to the interface at the upper end of the air inlet seat 51 via a flexible hose. The upper surface of the air inlet pipe 9 is provided with a downwardly inclined flange structure to prevent rainwater from entering the air inlet pipe 9.

[0032] The air intake support assembly 6 includes a support base 61 and an air pump 62. The support base 61 is installed on the lower crossbeam of the switching frame 43, and the support base 61 and the air intake head 52 are arranged vertically and vertically respectively. The air pump 62 is installed on the lower side of the interior of the housing 1. The air intake port of the air pump 62 is connected to the interface on the support base 61 through a hose. After the air pump 62 is started, it can draw in air from the external environment and pass it through the filter belt 10 to sample the ambient air.

[0033] Detector 7 is installed on the lower side of the air intake support assembly 6 and is used to detect air quality. Detector 7 detects the mass concentration of particulate matter in the air by emitting beta rays and detecting the number of beta ray particles, thereby obtaining air quality.

[0034] The working process of this invention is as follows: When it is necessary to monitor the air quality in the construction environment, the monitoring device is installed in the construction environment, the box door 2 is opened, the outer stop plate 35 is removed, several wound filter belts 10 are installed on the driven rotating shaft 31, and the filter belts 10 are pulled out and pasted onto the winding reel of the driving rotating shaft 32 through the two guide rollers 36. Then the outer stop plate 35 is installed to complete the feeding of multiple filter belts 10.

[0035] Driven by the power structure, the intake pressure head 52 can move downward, pressing it against the surface of the filter belt 10. The air pump 62 is started, and the air pump 62 draws ambient air from the intake pipe 9, which then passes through the intake seat 51, the filter belt 10 and the support seat 61 in sequence, so that the particulate matter in the air is retained on the surface of the filter belt 10. The concentration of particulate matter can be detected by the detector 7, thereby measuring the air quality.

[0036] After one test is completed, the air intake head 52 moves upward to reset, and the conveying motor 33 drives the active rotating shaft 32 to rotate, realizing intermittent conveying of the filter belt 10, so that the clean area of ​​the filter belt 10 is located between the air intake assembly 5 and the air intake support assembly 6, in order to complete the next test.

[0037] When a roll of filter tape 10 is used up, the switching motor 44 drives the switching shaft 42 to rotate, which in turn drives the switching frame 43 to rotate. The switching frame 43 then moves the air intake assembly 5 and the air intake support assembly 6 on it to the position of the next filter tape 10, so that the next filter tape 10 can be used for continued testing. With the same size as the existing device, this device can increase the service life of the device after a single maintenance by 6-8 times, which greatly facilitates the use of the monitoring device.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
