Description

Technical Field

[0001] The present invention belongs to the technical field of dust detection at construction sites, and particularly relates to an on-line sampling and detection device for construction dust Background Art

[0002] Dust will be generated during outdoor construction of civil engineering. Especially in dry and windy weather, the dust at the construction site will spread to the surrounding areas, which will affect the surrounding production and living environments. Dust pollution has been included in the environmental protection governance project. In order to prevent dust pollution, it is required to install enclosures around the construction site, and washing facilities and spraying systems are installed at the construction site. In addition to the above means of controlling dust, dust monitoring equipment also needs to be installed to monitor in real time to prevent large-scale spread of dust. The dust monitoring equipment includes a control box, a wind speed sensor, a wind direction sensor, a PM sensor, etc., which are usually fixed on a column. However, due to the continuous progress of the project at the construction site, the monitoring points need to be changed frequently. It is very inconvenient to replace the originally column-fixed dust monitoring equipment at the site. Therefore, it has gradually become a movable device.

[0003] For example, patent application No. CN202321551187.5 discloses an on-line sampling and detection device for construction dust. A support pipe is installed on a movable base. Rollers are provided through the bottom of the movable base. A circuit control board and a storage battery are installed in the control box on the movable base. A connection pipe is installed along the top of the support pipe, and a PM sensor is installed on the connection pipe. A wireless communication module and a solar panel are installed on the connection pipe. The storage battery, the PM sensor and the wireless communication module are respectively electrically connected to the circuit control board through wires, and the solar panel is electrically connected to the storage battery through wires. The PM sensor can be used to detect PM10 and PM2.5 at the construction site. Through the wireless communication module, network connection with the terminal device can be realized, and remote monitoring can be achieved. The solar panel and the storage battery are used to provide electric energy, eliminating the work of erecting wires. The movable base can move on the construction site by relying on the rollers, and the sampling and detection device can be transferred conveniently and quickly.

[0004] In the prior art, through a movable base in cooperation with structures such as a solar panel and a storage battery, the dust collection device can not only move quickly but also reduce work such as erecting wires, and can be effectively used in projects. However, there are still some deficiencies:

[0005] First of all, in the civil engineering environment, in addition to fine dust, large particle debris will also be mixed in the air. The existing dust detectors are directly exposed to the air and are easily impacted and damaged by particle debris in a strong wind environment. Regular maintenance is required. The overall service life is not good, and the accuracy of dust monitoring data cannot be guaranteed at the same time. There are certain deficiencies in the monitoring effect;

[0006] Secondly, although the existing equipment achieves the effect of self-power supply through photovoltaic panels, on the one hand, the lighting angle of the photovoltaic panels is always unified, resulting in poor lighting efficiency. On the other hand, the photovoltaic panels themselves are relatively large, and the fixing structure is prone to looseness and shaking in harsh environments such as strong winds, causing large-area shaking of the overall photovoltaic panels. The existing technology lacks a structure that can shock-absorb and reinforce, and there are certain deficiencies in the safety of the equipment.

[0007] Finally, the construction site environment is complex. Not all areas have flat ground and dry environments for equipment use. Although the existing equipment is equipped with crawling wheels for movement, it lacks a good fixing structure, resulting in the equipment often requiring a large number of external structures for reinforcement. While the operation is cumbersome, the overall applicability has certain deficiencies, and it cannot quickly adapt to fixing in different complex environments, affecting the installation efficiency. Summary of the Invention

[0008] In order to overcome the deficiencies of the prior art, the present invention provides an on-line sampling and detection device for construction dust. Through the settings of the inner mesh surface arc sleeve, the lever, and the downward-facing detection end of the dust detector in the dust detection component, while ensuring the normal flow of gas, large particle debris can be prevented from damaging the dust detector, effectively improving its service life. In cooperation with structures such as the first spherical seat, the double-headed ball rod, and the elastic arc plate, and also taking advantage of the characteristics of the mesh surface arc sleeve made of flexible rubber material, shock-absorbing and stabilizing treatment can be carried out on the already tensioned and fixed photovoltaic frame, effectively improving the overall service life of the equipment. In cooperation with the support and reinforcement component, the equipment can be applied to a variety of complex building construction environments, effectively improving the overall practical effect of the equipment.

[0009] In order to achieve the above object, the present invention provides the following technical solution: An on-line sampling and detection device for construction dust, including a base and a hollow column. The upper end surface of the base is fixedly provided with a hollow column, and a detection table is fixedly provided above the hollow column. A dust detection component is arranged on the end surface of the detection table, and a support and reinforcement component is arranged at the bottom of the base.

[0010] A photovoltaic frame is rotatably arranged above the detection table, and a plurality of photovoltaic panels are arranged on the end surface of the photovoltaic frame. The photovoltaic frame rotates according to the light source direction.

[0011] The dust detection component includes: an annular plate fixedly arranged above the detection table, and a dust detector fixedly arranged on the bottom end surface of the annular plate.

[0012] A mesh surface arc sleeve is arranged in an arc shape on the bottom end surface of the annular plate outside the dust detector. A plurality of grid holes for blocking large particle debris are arranged on the arc surface of the mesh surface arc sleeve.

[0013] A plurality of levers are evenly arranged in a circular shape and rotatably arranged on the outer arc surface of the mesh surface arc sleeve.

[0014] A second spherical seat is suspended above the center of the annular plate, and a first spherical seat is coaxially arranged on the bottom end face of the photovoltaic frame above the second spherical seat;

[0015] A double-headed ball rod is rotatably arranged between the first spherical seat and the second spherical seat, and the outer circumferential surface of the second spherical seat and the mesh arc sleeve are connected to each other through a plurality of elastic arc plates.

[0016] Through the arrangement of the mesh arc sleeve and the dial rod, the dust detector with the detection end facing downwards and not easily adhering to dust can avoid the damage of large particle debris to it while ensuring the stable gas flow, effectively guaranteeing the detection quality and greatly improving the service life. The arrangement of the elastic arc plates and the second spherical seat and other structures enables the photovoltaic frame to absorb and release vibrations when the external wind is strong in both the rotating and fixed states, which can not only make the photovoltaic frame tend to be stable, but also shake off the particulate dirt on the grid holes of the mesh arc sleeve, improving the detection effect of the dust detector.

[0017] In the above-mentioned on-line sampling and detection equipment for construction dust, a sorting cylinder is arranged between the detection table and the hollow column, and a control unit is arranged inside the sorting cylinder;

[0018] A processing box is arranged at the bottom of the base, and a power supply unit is arranged inside the processing box;

[0019] A control screen is arranged on the outer circumferential surface of the hollow column, and the inside of the hollow column is arranged in a hollow shape.

[0020] Through the arrangement of the sorting cylinder and the processing box, etc., the control unit, the power supply unit and the corresponding wire bodies that were originally exposed outside can be protected and are not easily damaged, effectively improving the overall service life of the equipment.

[0021] In the above-mentioned on-line sampling and detection equipment for construction dust, two second supports are fixedly arranged on one side of the bottom of the detection table, and a winding shaft is rotatably arranged inside the second supports;

[0022] A second fastening belt has one end wound around the outside of the winding shaft, and the other end of the second fastening belt is fixedly connected to one end of the bottom of the photovoltaic frame.

[0023] Through the arrangement of the second fastening belt and the winding shaft, etc., when the photovoltaic frame and the photovoltaic panel detect the light source direction, the angle can be adjusted in time to improve the photovoltaic power generation efficiency. When the external wind is strong, the photovoltaic frame can also tilt stably to one side to complete fixation and protect the detection parts on the end face of the detection table to a certain extent.

[0024] In the above-mentioned on-site construction dust online sampling and detection equipment, there are material cylinders. Two of the material cylinders are fixedly arranged on the other side of the bottom of the detection table, and torsion springs are arranged at both ends inside the material cylinders;

[0025] Torsion spring shaft, which is connected between the two torsion springs;

[0026] The first fastening belt. One end of the first fastening belt is wound around the outer circumferential surface of the torsion spring shaft, and the other end of the first fastening belt is connected to the other end of the bottom of the photovoltaic frame.

[0027] Through the settings of the torsion spring shaft and the first fastening belt, etc., while making the overall angle adjustment of the photovoltaic frame more convenient, when the winding shaft has completed winding in strong wind weather, an elastic tension fixation can be formed at one end of the photovoltaic frame to absorb the vibration and shaking of the photovoltaic frame and improve the stability of the photovoltaic frame. Compared with the structure of directly driving the rotation of the photovoltaic frame by a traditional motor, through the settings of the material cylinder and the winding shaft and other structures, the overall stability of the photovoltaic frame can be effectively improved.

[0028] In the above-mentioned on-site construction dust online sampling and detection equipment, the dust detection component further includes:

[0029] Support frame, which is arranged on the upper end surface of the detection table, and an annular plate is fixedly connected to the middle of the support frame;

[0032] Rotating coupling shaft, which is rotatably arranged between the centers of the refraction plate and the connection disk.

[0033] Through the settings of the refraction plate and the rotating coupling shaft and other structures, while enabling the dust and dirt scraped off by the dial rods to be discharged in time, the detection accuracy of the dust detector can also be improved.

[0034] In the above-mentioned on-site construction dust online sampling and detection equipment, a wind direction detector, which is fixedly arranged on one side of the upper end surface of the detection table;

[0035] Wind speed detector, which is fixedly arranged on the other side of the upper end surface of the detection table;

[0036] Crawler wheels, and a plurality of the crawler wheels are rotatably arranged on both side walls of the processing box.

[0037] Through the settings of the wind direction detector and the wind speed detector, etc., the equipment can complete the acquisition and processing of various data.

[0038] In the above-mentioned on-site construction dust online sampling and detection equipment, the support and reinforcement assembly includes:

[0039] First opening holes, two of the first opening holes are arranged on the base end face above one side of the crawler wheels, and a baffle is slidably arranged in the first opening holes;

[0040] Rough panel, the rough panel is fixedly arranged on the bottom end face of the baffle;

[0041] First fixing nails, a plurality of the first fixing nails are arranged on one side of the bottom of the rough panel through a detachable structure;

[0042] Second fixing nails, a plurality of the second fixing nails are arranged on the other side of the bottom of the rough panel through a detachable structure.

[0043] Through the arrangement of structures such as the baffle, the rough panel and the first fixing nails, during the crawling process of the equipment, there is always a protective structure on the outside of the processing box and the crawler wheels, making the movement of the equipment safer. When the equipment is fixed, the processing box can also be lifted upward away from the ground, making it difficult for moisture, insects, birds and animals to enter. This effectively improves the service life inside the processing box, reduces the maintenance times, and at the same time ensures the overall fixing effect.

[0044] In the above-mentioned on-site construction dust online sampling and detection equipment, the support and reinforcement assembly further includes:

[0045] Second opening holes, two of the second opening holes are arranged on the base end face on one side of the first opening holes, a rotating bearing is arranged in the second opening holes, and a second rotating seat is arranged on the end face of the rough panel below the second fixing nails;

[0046] Rotating rod, the middle part of the rotating rod is rotatably arranged on the rotating bearing, and one end of the bottom of the rotating rod is connected to the second rotating seat;

[0047] Handle, the handle is arranged on one end of the top of the rotating rod.

[0048] Through the arrangement of structures such as the rotating rod and the handle, it enables the staff to complete the support and movement processing of the equipment only by swinging the inclination angle of the rotating rod. In this solution, there are no excessive restrictions on how the rotating rod swings. It can be swung manually or pushed by a mechanical structure.

[0049] In the above-mentioned on-site construction dust online sampling and detection equipment, the support and reinforcement assembly further includes:

[0050] Mounting seat, the mounting seat is arranged on the outer end face of the rotating rod, and a fixing bolt is slidably arranged in the mounting seat;

[0051] A bolt hole is provided on the base end face directly below the fixing bolt. When the fixing bolt is fitted with the bolt hole, the rough panel is supported.

[0052] Connectors, two of which are respectively arranged on one side wall of the handle and the end face of the base.

[0053] A connector, with both ends of the connector being threadedly fitted with the connectors. When the connection is completed, the rough panel is lifted upward.

[0054] Through the arrangement of the fixing bolt and the bolt hole, the overall fixing effect is ensured when the device is fixed. And the arrangement of the connectors and the connector enables the rough panel to be always separated from the ground during the movement of the device, so that the device can be effectively moved.

[0055] In the above-mentioned on-line sampling and detection equipment for construction dust, a push cylinder is inclinedly arranged on one side of the second support at the bottom end face of the detection table. The output end of the push cylinder is connected with a clamping head, and a limiting block is arranged on the clamping head. The outer end of the limiting block abuts against the coiled material formed by the second fastening belt. Through the arrangement of structures such as the push cylinder and the limiting block, after the second fastening belt is wound up, the outside can be effectively clamped and fixed, effectively improving the fixing effect on the photovoltaic frame.

[0056] To sum up, compared with the prior art, the beneficial effects of this solution are as follows:

[0057] (1) Through the arrangement of structures such as the mesh surface arc sleeve and the dust detector, and the lever and the refraction plate, the detection end of the dust detector faces downward and is not easily adhered to by dust and dirt. When the detection accuracy can be improved, while ensuring the gas flow efficiency, large particle debris can be blocked from damaging the dust detector, effectively improving the overall service life and reducing the maintenance frequency.

[0058] (2) Through structures such as the first spherical seat, the double-headed ball rod, and the elastic arc plate, when the photovoltaic frame is effectively tensioned and fixed by the first fastening belt, the second fastening belt, and the coiling shaft, etc., when the photovoltaic frame rotates or is in a fixed state, when there is strong wind outside, part of the vibration and shaking can be absorbed and released through the mesh surface arc sleeve, etc. While effectively improving the stability of the photovoltaic frame, the particulate dirt adhered to the mesh surface arc sleeve will also be shaken off, effectively improving the detection efficiency.

[0059] (3) Through the settings of structures such as the first fastening belt, the second fastening belt, the coiling shaft, and the limiting block, the present invention enables the photovoltaic frame to adjust the angle in a timely manner according to the light source to improve the photovoltaic power generation efficiency. At the same time, in an overall harsh environment, it can absorb and relieve vibrations, effectively improving the stability of the overall photovoltaic frame and photovoltaic panel, etc., and effectively ensuring the overall service life of the equipment.

[0060] (4) Through the settings of structures such as the baffle, the rough panel, and the first fixing nail, the present invention enables there to always be a protective structure on the outside of the processing box and the crawling wheels during the crawling process of the equipment, making the movement of the equipment safer. When the equipment is fixed, the processing box can also be lifted upward away from the ground, making it difficult for moisture, insects, birds, and beasts to enter. This effectively improves the service life inside the processing box, reduces the maintenance frequency, and at the same time ensures the overall fixing effect.

[0061] (5) Through the settings of the placement cylinder and the processing box, etc., the present invention enables the originally externally exposed control unit, power supply unit, and corresponding wire bodies to be protected, making them not easily damaged, and effectively improving the overall service life of the equipment.

Detailed implementation manners

[0077] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0078] Embodiment 1:

[0079] Refer to attached Figure 1 and attached Figure 2 and attached Figure 3 and attached Figure 4 and attached Figure 5, a dust online sampling and detection device for civil engineering construction. To facilitate the effective adaptation of the device to various construction sites, a base 10 and a processing box 39 are provided. The processing box 39 is arranged on the bottom end face of the base 10. A power supply unit 40 is placed inside the processing box 39. The power supply unit 40 is a prior art, including a storage battery and a wiring port. The specific structure is not elaborated in this solution. The power supply unit 40 is used to supply power to the whole device and store electricity. In this solution, the relatively heavy power supply unit 40 is placed in the processing box 39 at the bottom of the base 10, which can also make the overall center of gravity of the device move downward, improve the stability of the overall device, and also enable the device to work normally for a short time in the case of external power failure. A plurality of driving motors are arranged at both ends inside the processing box 39. The output ends of the plurality of driving motors extend out of the end face of the processing box 39. A detachable and replaceable crawler wheel 37 is arranged at the end of the driving motor extending out of the end face of the processing box 39. The crawler wheel 37 is driven to rotate by the output end of the driving motor, so as to complete the rapid movement processing of the device. Support and reinforcement components are arranged on both sides of the processing box 39. After the device completes the movement, the overall device can be fixed by the support and reinforcement components.

[0080] A fixing seat 19 is arranged on the upper end face of the base 10. A hollow column 11 is supported and fixed inside the fixing seat 19. The inside of the hollow column 11 is hollow. A sorting cylinder 31 is communicated and arranged at the top end of the hollow column 11. The control unit 41 is placed in the sorting cylinder 31. Multiple detection components in the device are uniformly controlled and allocated by the control unit 41, which is a prior art and not elaborated in this solution. The upper end face of the sorting cylinder 31 is open, and a conical cover plate 24 is arranged in internal thread fit. The conical cover plate 24 can seal the sorting cylinder 31. The staff can also open the conical cover plate 24 to maintain the control unit 41 inside the sorting cylinder 31. Since the inside of the hollow column 11 is hollow, the wires and signal lines required by the control unit 41 can be placed inside the hollow column 11 and led out downward to complete the wiring, so as to reduce the occurrence of flying wires and improve the overall safety of the device. In this relationship, a control screen 18 can be installed at any height outside the hollow column 11 to control the work of the whole device.

[0081] Refer to the appendix Figure 1 and the appendix Figure 5, a detection platform 12 is fixedly arranged outside the top of the placement cylinder 31. Above the detection platform 12, a dust detection component is arranged. The dust detection component will perform real-time detection and processing on the dust content in the air. On one side of the dust detection component, a wind direction detector 23 is arranged on the end face of the detection platform 12. The wind direction detector 23 is used to detect the flow direction of the wind. On the other side of the dust detection component and on the end face of the detection platform 12, a wind speed detector 22 is arranged. The wind speed detector 22 can perform real-time monitoring and processing on the wind speed. To ensure that the equipment can be used for a long time, a photovoltaic frame 13 is also rotatably arranged above the detection platform 12. On the end face of the photovoltaic frame 13, a plurality of photovoltaic panels 14 are arranged. The plurality of photovoltaic panels 14 and the photovoltaic frame 13 can generate electricity through photovoltaic means and supply the electric energy to the equipment for use, so that the equipment can be used for a short time without being connected to an external power supply, enabling the equipment to adapt to more complex construction environments and improving the applicable range.

[0082] Further, referring to Appendix Figure 6 and Appendix Figure 7 , the dust detection component includes a support frame 34 fixedly arranged on the end face of the detection platform 12. In the middle of the support frame 34, an annular plate 32 is fixedly arranged. On the bottom end face of the annular plate 32, a mesh surface arc sleeve 33 made of flexible rubber material is arranged. The bottom of the mesh surface arc sleeve 33 is open, and the middle part is arc-shaped. On the middle arc surface of the mesh surface arc sleeve 33, a plurality of grid holes for the flow of dust gas are arranged. In the middle of the mesh surface arc sleeve 33 and on the end face of the annular plate 32, a dust detector 49 is arranged. The detection end of the dust detector 49 faces downward. In this solution, the dust detector 49 is based on the principle of light scattering. A light beam is emitted by an LED lamp or a laser. When particulate matter in the air enters the light beam, the light beam will be scattered on the particulate matter. At this time, the detection end on the dust detector 49 determines the concentration and particle size of the particulate matter by detecting the intensity and angle of the scattered light, etc.;

[0083] The mesh surface arc sleeve 33 is arranged outside the dust detector 49, which can filter and block large-particle sand and gravel debris in the air, avoid damage to the dust detector 49 caused by large-particle sand and gravel debris, and improve the service life of the dust detector 49. At the same time, the detection end of the dust detector 49 faces downward. Compared with the traditional upward arrangement, the situation of dust and dirt accumulating on the detection end is reduced, and the use time after a single maintenance can be extended to a certain extent. The overall bottom of the mesh surface arc sleeve 33 is open, which is convenient for gas flow and the filtered particulate dirt can also quickly fall off, reducing the situation of accumulation inside the mesh surface arc sleeve 33.

[0084] Even further, referring to Appendix Figure 6 and Appendix Figure 7, To ensure the gas flow of the mesh arc sleeve 33 and prevent the grid holes from being blocked, a support plate 52 is fixedly connected inside the support frame 34 below the mesh arc sleeve 33. A dust removal motor 53 is fixedly arranged on the upper end surface of the support plate 52. A connection disk 47 is connected to the output end surface of the dust removal motor 53. A plurality of dial rods 48 are circumferentially connected to the outer circumferential surface of the connection disk 47. The plurality of dial rods 48 are arc-shaped and fit on the outside of the mesh arc sleeve 33. The arc surface where the dial rods 48 fit on the outside of the mesh arc sleeve 33 is roughened. After the mesh arc sleeve 33 is used for a long time, dust particles are likely to block the grid holes. At this time, the output end of the dust removal motor 53 can drive the connection disk 47 to rotate, thereby driving the plurality of dial rods 48 to rotate. The rotating dial rods 48 will continuously scrape the outer surface of the mesh arc sleeve 33, so as to scrape off the dust and dirt accumulated on the grid holes of the mesh arc sleeve 33. In this solution, the dial rods 48 are formed by braiding elastic metal wires, which have a certain toughness and elasticity at the same time. When scraping the outer surface of the mesh arc sleeve 33, when encountering particle protrusions, they can move and shake, so as to bounce the particle dust and make it fall smoothly to complete the cleaning process;

[0085] In this solution, to ensure that the dust detector 49 can smoothly collect data and the emitted light beam can be smoothly collected, a refraction plate 50 with a conical top is arranged below the mesh arc sleeve 33 to improve the collection effect. This is prior art. Making it conical is to ensure that the fallen dust and dirt can be smoothly discharged. There is a certain gap between the refraction plate 50 and the mesh arc sleeve 33 for the dust and dirt to be discharged. A rotating connecting shaft 51 is rotatably connected in the middle between the refraction plate 50 and the connection disk 47. When the connection disk 47 rotates, due to the rotational cooperation between the rotating connecting shaft 51 and the connection disk 47, the rotating connecting shaft 51 and the refraction plate 50 will not rotate, so that the refraction plate 50 can be lifted below the mesh arc sleeve 33 without blocking the bottom opening of the mesh arc sleeve 33, ensuring the refraction efficiency and improving the dust removal efficiency at the same time.

[0086] Further, referring to Appendix Figure 1 Appendix Figure 2 and Appendix Figure 3 , on both sides of the upper end surface of the detection table 12, brackets 25 are fixedly arranged. A first rotating seat 29 is fixedly arranged on the upper end surface of the bracket 25. A rotating block 30 is rotatably arranged in the first rotating seat 29. The upper end surfaces of the two rotating blocks 30 are fixedly connected to the photovoltaic frame 13, so that the photovoltaic frame 13 will rotate around the rotation connection point between the two rotating blocks 30 and the first rotating seat 29, so that the photovoltaic frame 13 can adjust the angle according to the rise and fall of the sun in sunny weather, so that the plurality of photovoltaic panels 14 can generate electricity better. A sensor for sensing light sources is arranged on the photovoltaic frame 13 to sense light sources. This is prior art and will not be elaborated in this solution.

[0087] Referring to AppendixFigure 8 and append Figure 9 and append Figure 10 , on both sides of the bottom side of the detection table 12, two second supports 36 are fixedly arranged. A coiling shaft 55 is rotatably arranged in each of the two second supports 36. On one side of the coiling shaft 55 outside the second support 36, a motor capable of automatically locking is arranged. The output end of the motor is connected to the end face of the coiling shaft 55. A second fastening belt 68 is wound around the outer circumferential surface of the coiling shaft 55. One end of the second fastening belt 68 is connected to the bottom end of the photovoltaic frame 13. On one side of the second support 36, a first support 21 is fixedly arranged on the bottom end face of the detection table 12. A cartridge 20 is fixedly arranged in the first support 21. A torsion spring shaft 54 is rotatably arranged in the cartridge 20. Torsion springs 67 are connected to both ends of the torsion spring shaft 54 inside the cartridge 20. A first fastening belt 26 is also wound around the outer circumferential surface of the torsion spring shaft 54. The other end of the first fastening belt 26 extends out of the cartridge 20 and is connected to the bottom end of the photovoltaic frame 13. Therefore, the first fastening belts 26 and the second fastening belts 68 wound around the two coiling shafts 55 and the two torsion spring shafts 54 form a state of mutual pulling at the bottom of the photovoltaic frame 13. In this solution, both the first fastening belt 26 and the second fastening belt 68 are internally flexible metal wires and externally anti-slip rubber layers, having a certain strength and toughness;

[0088] Therefore, when the photovoltaic frame 13 needs to rotate an angle, the motor on one side of the second support 36 will drive the coiling shaft 55 to rotate clockwise or counterclockwise, so as to drive the second fastening belt 68 outside the coiling shaft 55 to be wound or unwound, thereby pulling the entire photovoltaic frame 13 to tilt downward toward the coiling shaft 55 side to complete the angle adjustment process. At this time, the other side of the photovoltaic frame 13 will tilt upward, and the first fastening belt 26 outside the torsion spring shaft 54 will also be released outward, causing the torsion springs 67 on both sides of the torsion spring shaft 54 to be stressed, so there will also be tension at the tilting end of the photovoltaic frame 13, thereby improving the overall fixing effect of the photovoltaic frame 13. When the photovoltaic frame 13 needs to rotate toward the torsion spring shaft 54 side, the coiling shaft 55 will unwind, and the torsion springs 67 on both sides of the torsion spring shaft 54 will also release the pressure to drive the torsion spring shaft 54 to rotate, so as to wind the first fastening belt 26 outside the torsion spring shaft 54 inward, enabling the photovoltaic frame 13 to complete the flipping smoothly. In this solution, the connection method of the torsion springs 67 at both ends of the torsion spring shaft 54 is an existing structure, and the attached drawings do not show it in detail.

[0089] Furthermore, referring to append Figure 8 and append Figure 9 and append Figure 10, to ensure the stability of the photovoltaic frame 13, an inclined push cylinder 57 is fixedly arranged at the bottom of the inspection table 12 on one side of the second support 36. The push cylinder 57 is an electric drive cylinder body. A clamping head 58 is connected to the output end of the push cylinder 57. A detachable limit block 56 is arranged on the end face of the clamping head 58. The limit block 56 is made of anti-slip rubber material and its surface is roughened. After the angle adjustment of the photovoltaic frame 13 is completed, the output end of the push cylinder 57 will push the clamping head 58 to move outwards, so as to push the limit block 56 at one end of the clamping head 58 to abut against the outer circumference of the second fastening belt 68 wound around the winding shaft 55, so as to clamp and fix the second fastening belt 68, so that the second fastening belt 68 wound around the outside of the winding shaft 55 cannot be pulled continuously, and the photovoltaic frame 13 at one end of the second fastening belt 68 is fixed. In this solution, when strong winds occur outside, the winding shaft 55 in the second support 36 will completely wind the second fastening belt 68 inwards, making the whole photovoltaic frame 13 tilt completely towards the side of the winding shaft 55. Subsequently, the push cylinder 57 will also increase the power to press the pressure between the limit block 56 and the winding of the second fastening belt 68, so as to improve the overall stability of the photovoltaic frame 13, improve the durability of the photovoltaic frame 13 in the harsh environment of strong winds, reduce damage. At the same time, the overall tilt of the photovoltaic frame 13 can also protect the multiple detection parts on the end face of the inspection table 12, and can also reduce the damage of the detection parts on the end face of the inspection table 12, and improve the overall service life of the equipment.

[0090] Embodiment 2:

[0091] Reference appendix Figure 11 Appendix Figure 12 Appendix Figure 13 And appendix Figure 14, a dust online sampling and detection device for civil engineering construction. The support and reinforcement component includes first opening holes 27 arranged on both sides of the processing box 39 on the end face of the base 10. A baffle 15 is slidably arranged up and down in the first opening holes 27. A rough panel 16 is arranged on the bottom end face of the baffle 15. The whole bottom of the rough panel 16 is roughened. A plurality of detachable first fixing nails 59 are arranged on one side of the bottom end face of the rough panel 16, and a plurality of second fixing nails 60 are arranged on the other side of the bottom of the rough panel 16. When the device crawls, the baffle 15 and the rough panel 16 will move upward so that the bottom end face of the rough panel 16 will not contact the ground, enabling the device to crawl smoothly. However, the baffle 15 and the rough panel 16 as a whole will block the outside of the crawling wheels 37, thereby protecting the crawling wheels 37 and reducing the possibility of damage to the crawling wheels 37. When the device stops moving, at this time, the baffle 15 and the rough panel 16 will move downward. Subsequently, the whole bottom of the rough panel 16 will press on the ground. Then, as the rough panel 16 continues to move downward, it will lift the whole base 10 upward, making the crawling wheels 37, the processing box 39 and the ground move away from each other. And the baffle 15 will still block the outside of the processing box 39 and the crawling wheels 37 and protect them until the rough panel 16 is completely fixed. This setting can ensure that the crawling wheels 37 and the processing box 39 are less likely to be damaged by bumps, improving the overall service life of the device. Moving the processing box 39 away from the ground can reduce the entry of ground moisture or other insects, birds and animals into the processing box 39, enabling the power supply or control structure in the processing box 39 to operate stably, increasing the service life, reducing the maintenance frequency, and being better applicable to complex construction environments;

[0092] The first fixing nails 59 and the second fixing nails 60 on the bottom of the rough panel 16 are set according to the actual situation. The first fixing nails 59 are relatively short and suitable for short-term fixation, while the second fixing nails 60 are long and thick and suitable for long-term fixation processing. The staff set them according to actual needs. The detachable structure is prior art and will not be elaborated in this solution.

[0093] Further, referring to Att Figure 11 、Att Figure 12 、Att Figure 13 and Att Figure 14 , two second opening holes 28 are arranged on the end face of the base 10 on one side of the first opening holes 27. Rotating bearings 66 are arranged in both of the two second opening holes 28. A rotating rod 17 is rotatably connected to the outside of the rotating bearings 66. One end of the rotating rod 17 extends out of the upper end of the second opening hole 28. A handle 35 is connected to the end of the rotating rod 17 extending out of the upper end of the second opening hole 28. The other end of the rotating rod 17 extends out of the lower end of the second opening hole 28. A second rotating seat 38 is rotatably arranged at the end of the rotating rod 17 extending out of the lower end of the second opening hole 28. The bottom end of the second rotating seat 38 is fixedly arranged at the upper end of the rough panel 16.

[0094] When the rough panel 16 needs to move up and down, the staff only needs to grab the handle 35, and then push the rotating rod 17 to swing forward or backward on both sides. The rotating rod 17 will rotate at an angle with the rotating bearing 66 as the center, so as to drive one end of the bottom to tilt upward or downward, thereby driving the second rotating seat 38 to move up and down, and then driving the rough panel 16 and the baffle 15 to complete the up and down movement. In this solution, when the middle rotating rod 17 is centered vertically, the rough panel 16 completes the support and fixation state.

[0095] Embodiment Three:

[0096] Reference appendix Figure 12 and appendix Figure 13 and appendix Figure 14 Refer to appendix

[0097] On the outer end face side of the rotating rod 17 extending out of the base 10, a fixing bolt 62 is fixedly arranged. A fixing bolt 62 is slidably arranged in the fixing bolt 62. A bolt hole 65 is arranged on the end face of the base 10 below the fixing bolt 62. When the rough panel 16 completes the support and fixation, at this time the rotating rod 17 is in the centered state. The staff can screw the fixing bolt 62 downward so that one end of the fixing bolt 62 is screwed into the bolt hole 65, thereby fixing the rotating rod 17, preventing the rotating rod 17 from shaking, and fixing the baffle 15 and the rough panel 16 below the rotating rod 17 as a whole, and effectively fixing the whole device.

[0098] Embodiment Four:

[0099] Reference appendix Figure 6 and appendix Figure 7, an online sampling and detection device for dust from civil construction, a plurality of arc openings 42 are arranged on the upper end surface of the annular plate 32, a second spherical seat 45 is arranged coaxially with the annular plate 32 above the arc opening 42, a plurality of elastic arc plates 43 made of elastic material are connected and arranged on the outer circumferential surface of the second spherical seat 45, the other ends of the plurality of elastic arc plates 43 all pass through the arc opening 42 and are fixedly connected to the upper end surface of the mesh arc sleeve 33, a first spherical seat 44 is fixedly arranged on the bottom end surface of the photovoltaic frame 13 above the second spherical seat 45, and a double-headed ball rod 46 is rotatably connected to the ball head between the first spherical seat 44 and the second spherical seat 45.

[0100] When the photovoltaic frame 13 rotates toward the second support 36, the whole is relatively stable due to the relationship between the motor and the push cylinder 57. However, when it rotates toward the barrel 20, the photovoltaic frame 13 has certain instability due to the effect of only the torsion spring 67. When affected by external gas flow, the photovoltaic frame 13 will produce certain vibrations and shakes due to adapting to the gas flow. At this time, the torsion spring 67 in the barrel 20 can absorb certain shaking to ensure that the photovoltaic frame 13 does not shake too much, and the photovoltaic frame 13 will also drive the first spherical seat 44 at the bottom to produce certain vibrations and shakes, thereby driving the double-headed ball rod 46 and the second spherical seat 45 at the bottom of the double-headed ball rod 46 to shake up, down, left and right. At this time, the multiple elastic arc plates 43 outside the second spherical seat 45 and the mesh arc sleeve 33 at one end of the bottom of the elastic arc plate 43 will also transmit shaking or vibration and It is absorbed and released, so that although the photovoltaic frame 13 as a whole will have a slight shake, it will not produce vibration and shaking, etc., thereby ensuring its stability. When the mesh arc sleeve 33 absorbs the vibration, the mesh arc sleeve 33 is also receiving the vibration, so the mesh arc sleeve 33 will also produce a certain shake, thereby squeezing and shaking off the dust and dirt accumulated on the grid holes of the mesh arc sleeve 33, so that the gas in the mesh arc sleeve 33 is always guaranteed to circulate efficiently, and the dust detection efficiency can also be improved. In this scheme, the first spherical seat 44, the double-headed ball rod 46 and the second spherical seat 45 are arranged, so that the photovoltaic frame 13 can effectively transmit force no matter which direction it rotates, and the elastic elastic arc plate 43 also allows the suspended second spherical seat 45 to rise or fall appropriately to adjust the height, so that the vibration and shaking can be better absorbed and transmitted, thereby improving stability.
