Description

Technical Field

[0001] The invention belongs to the technical field of construction site dust detection, and in particular relates to an online sampling and detection device for civil construction dust. Background Art

[0002] Civil construction will generate dust when working outdoors, especially in dry and windy weather. The dust at the construction site will spread to the surrounding area, affecting the surrounding production and living environment. Dust pollution has been included in the environmental protection management project. In order to prevent dust pollution, it is required to install fences around the construction site, and install flushing facilities and sprinkler systems at the construction site. In addition to the above-mentioned means of controlling dust, dust monitoring equipment must also be installed for real-time monitoring to prevent large-scale spread of dust. Dust monitoring equipment includes control boxes, wind speed sensors, wind direction sensors, PM sensors, etc., which are usually fixed on columns. However, as the construction site project will continue to advance, the monitoring points also need to be replaced frequently. The original columnar fixed dust monitoring equipment is very inconvenient to change the site, so it has gradually become a movable device.

[0003] For example, patent application number CN202321551187.5 discloses an online sampling and detection device for dust in civil construction. A support tube is installed on a movable base, rollers are installed at the bottom of the movable base, and a circuit control board and a battery are installed in the control box on the movable base. A PM sensor is installed along the top of the connecting tube at the top of the support tube. A wireless communication module and a solar panel are installed on the connecting tube. The battery, PM sensor and wireless communication module are electrically connected to the circuit control board through wires, and the solar panel is electrically connected to the battery through wires. The PM sensor can be used to detect PM10 and PM2.5 at the construction site, and the wireless communication module can be used to connect to the terminal device to achieve network connection, so that remote monitoring can be achieved. Solar panels and batteries are used to provide electrical energy, eliminating the work of laying wires. The movable base can be moved around the construction site by rollers, and the sampling and detection device can be transferred conveniently and quickly.

[0004] In the prior art, the dust collection equipment can be moved quickly and reduce the work of laying wires by using a movable base in combination with solar panels and batteries, and can be effectively used in engineering projects. However, there are still some shortcomings: First, in civil engineering environments, the air contains not only fine dust but also large particles of debris. Existing dust detectors are directly exposed to the air and are easily hit and damaged by particles and debris in windy environments. They require regular maintenance, and their overall service life is poor. At the same time, the accuracy of dust monitoring data cannot be guaranteed, and the monitoring effect is somewhat insufficient. Secondly, although the existing equipment achieves the effect of self-power supply through photovoltaic panels, the lighting angle of photovoltaic panels is always uniform, and the lighting efficiency is poor. On the other hand, the photovoltaic panels themselves are large, and the fixed structure is easy to loosen and shake in severe environments such as strong winds, causing the entire photovoltaic panel to shake over a large area. The existing technology lacks a structure that can reduce shock and strengthen, and there are certain deficiencies in the safety of the equipment; Finally, the construction site environment is complex, and not all areas have flat ground and dry environment for equipment use. Although the existing equipment is equipped with crawler wheels to complete movement, it lacks a good fixing structure, which means that the equipment often requires a large amount of external structure for reinforcement. The operation is cumbersome and the overall applicability has certain shortcomings. It cannot quickly adapt to fixation in different complex environments, affecting the installation efficiency. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides an online sampling and detection device for dust in civil construction. The present invention arranges the mesh arc sleeve and the lever in the dust detection component and the detection end of the dust detector downward, which can avoid large particles of debris from damaging the dust detector while ensuring the normal flow of gas, effectively improving its service life. In combination with the first spherical seat, the double-headed ball rod, the elastic arc plate and other structures, the characteristics of the mesh arc sleeve made of flexible rubber material can also be used to perform shock-absorbing and stabilizing treatment on the photovoltaic frame that has been tensioned and fixed, effectively improving the overall service life of the equipment, and in combination with the support and reinforcement components, the equipment can be applied to a variety of complex construction environments, effectively improving the overall practical effect of the equipment.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an online sampling and detection device for dust in civil construction, comprising a base, a hollow column, a hollow column fixedly arranged on the upper end surface of the base, a detection platform fixedly arranged above the hollow column, a dust detection component arranged on the end surface of the detection platform, and a support reinforcement component arranged at the bottom of the base. A photovoltaic frame, which is rotatably arranged above the detection platform, and a plurality of photovoltaic panels are arranged on the end surface of the photovoltaic frame, and the photovoltaic frame rotates at an angle according to the direction of the light source; The dust detection assembly comprises: an annular plate, the annular plate is fixedly arranged above the detection platform, and a dust detector is fixedly arranged on the bottom end surface of the annular plate; A mesh arc sleeve, the mesh arc sleeve is arranged in an arc shape on the bottom end surface of the annular plate outside the dust detector, and a plurality of grid holes for blocking large particles of debris are arranged on the arc surface of the mesh arc sleeve; A plurality of levers are arranged in an annular shape and are evenly rotated on the outer arc surface of the mesh arc sleeve; A second spherical seat, wherein the second spherical seat is suspended above the center of the annular plate, and a first spherical seat is coaxially arranged on the bottom end surface of the photovoltaic frame above the second spherical seat; A double-headed golf club is rotatably arranged between a first spherical seat and a second spherical seat, wherein 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.

[0007] Through the arrangement of the mesh arc sleeve and the lever, the dust detector, which originally had its detection end facing downward and was not easily sticky to dust, can ensure the stability of gas flow while avoiding damage by large particles of debris, effectively ensuring the detection quality while greatly improving its service life. The arrangement of structures such as the elastic arc plate and the second spherical seat allows the photovoltaic frame to absorb and release vibrations when strong winds occur outside while it is rotating and fixed, which can not only stabilize the photovoltaic frame, but also shake off particles and dirt on the grid holes of the mesh arc sleeve, thereby improving the detection effect of the dust detector.

[0008] In the above-mentioned online sampling and detection equipment for civil construction dust, a return tube is arranged between the detection platform and the hollow column, and a control unit is arranged inside the return tube; A processing box, the processing box is arranged at the bottom of the base, and a power supply unit is arranged in the processing box; A control panel is arranged on the outer circumferential surface of the hollow column, and the interior of the hollow column is arranged in a hollow shape.

[0009] Through the settings of the storage tube and the processing box, the control unit, the power supply unit and the corresponding wires originally exposed to the outside can be protected so that they will not be easily damaged, thereby effectively improving the overall service life of the equipment.

[0010] In the above-mentioned civil construction dust online sampling and detection equipment, the second support, two of which are fixedly arranged on one side of the bottom of the detection platform, and a coiling shaft is rotatably arranged in the second support; A second fastening belt, one end of which is wound around the outside of the coiling shaft, and the other end of which is fixedly connected to one end of the bottom of the photovoltaic frame.

[0011] Through the settings of the second fastening belt and the winding shaft, the photovoltaic frame and the photovoltaic panel can adjust the angle in time when detecting the direction of the light source, thereby improving the efficiency of photovoltaic power generation. When strong winds appear outside, the photovoltaic frame can also be firmly tilted to one side to complete the fixation, and the detection parts on the end surface of the detection table are protected to a certain extent.

[0012] In the above-mentioned civil construction dust online sampling and detection equipment, the barrel, two of the barrels are fixedly arranged on the other side of the bottom of the detection platform, and torsion springs are arranged at both ends of the barrel; A torsion spring shaft connected between two torsion springs; A first tightening belt, one end of which is wound around the outer circumferential surface of the torsion spring shaft, and the other end of which is connected to the other end of the bottom of the photovoltaic frame.

[0013] Through the settings of the torsion spring shaft and the first tightening belt, the overall adjustment of the angle of the photovoltaic frame is more convenient. In windy weather, when the winding shaft has completed winding, 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 the traditional motor directly driving the photovoltaic frame to rotate, the overall stability of the photovoltaic frame can be effectively improved through the settings of the barrel and the winding shaft.

[0014] In the above-mentioned civil construction dust online sampling and detection equipment, the dust detection component also includes: A support frame, the support frame is arranged at the upper end surface of the detection platform, and the middle part of the support frame is fixedly connected to the annular plate; A connecting disk, the connecting disk is rotatably arranged below the mesh arc sleeve, and the outer circumferential surface of the connecting disk is interconnected with a plurality of levers; A refraction plate, wherein the refraction plate is fixedly arranged below the support frame, and a certain gap exists between the refraction plate and the bottom of the support frame; The rotating connecting shaft is rotatably arranged between the centers of the refraction plate and the connection disk.

[0015] By arranging structures such as the refraction plate and the rotating shaft, the dust and dirt scraped off by the lever can be discharged in time, and the detection accuracy of the dust detector can also be improved.

[0016] In the above-mentioned civil construction dust online sampling and detection equipment, a wind direction detector is fixedly arranged on one side of the upper end surface of the detection platform; A wind speed detector, which is fixedly arranged on the other side of the upper end surface of the detection platform; Crawling wheels, a plurality of the crawling wheels are rotatably arranged on the two side walls of the processing box.

[0017] Through the settings of wind direction detectors and wind speed detectors, the equipment can complete the collection and processing of various data.

[0018] In the above-mentioned civil construction dust online sampling and detection equipment, the support reinforcement component includes: First opening holes, two of which are arranged on the end surface of the base above the crawler wheel, and baffles are slidably arranged in the first opening holes; A rough panel, wherein the rough panel is fixedly disposed on the bottom end surface of the baffle; 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; Second fixing nails, a plurality of second fixing nails are arranged on the other side of the bottom of the rough panel through a detachable structure.

[0019] By setting up structures such as the baffle, the rough panel and the first fixing nail, there is always a protective structure on the outside of the processing box and the crawling wheel 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 animals to enter, effectively improving the service life of the inside of the processing box, reducing the number of maintenance times and ensuring the overall fixing effect.

[0020] In the above-mentioned civil construction dust online sampling and detection equipment, the support reinforcement component also includes: A second opening hole, wherein two of the second opening holes are arranged on the end surface of the base on one side of the first opening hole, a rotating bearing is arranged in the second opening hole, and a second rotating seat is arranged on the end surface of the rough panel below the second fixing nail; A rotating rod, wherein the middle portion of the rotating rod is rotatably disposed on a rotating bearing, and one end of the bottom of the rotating rod is connected to the second rotating seat; A handle is arranged on one end of the top of the rotating rod.

[0021] By setting up structures such as a rotating rod and a handle, the staff can complete the support and movement of the equipment by only swinging the tilt angle of the rotating rod. In this solution, there are no excessive restrictions on how the rotating rod swings, and it can be swung manually or pushed by a mechanical structure.

[0022] In the above-mentioned civil construction dust online sampling and detection equipment, the support reinforcement component also includes: A mounting seat, the mounting seat is arranged on the outer end surface of the rotating rod, and a fixing bolt is slidably arranged in the mounting seat; A bolt hole, wherein the bolt hole is arranged on the end surface of the base directly below the fixing bolt, and the rough panel completes the support when the fixing bolt and the bolt hole are matched; Connectors, two of which are respectively arranged on one side wall of the handle and the end surface of the base; The connector has two ends which are respectively threadedly matched with the connector head, and the rough panel is lifted upward when the connector is connected.

[0023] By setting the fixing bolts and bolt holes, the overall fixing effect of the equipment is guaranteed when it is fixed, and the setting of the connecting head and the connector ensures that the rough panel is always off the ground during the movement of the equipment, so that the equipment can be effectively moved.

[0024] In the above-mentioned online sampling and detection equipment for civil construction dust, a push cylinder is obliquely arranged on one side of the second support on the bottom end surface of the detection platform, and a clamping head is connected to the output end of the push cylinder, and a limit block is arranged on the clamping head, and one end of the limit block is abutted against the coil formed by the second fastening belt. Through the arrangement of the push cylinder and the limit block and other structures, the second fastening belt can be effectively clamped and fixed on the outside after winding, which effectively improves the fixing effect of the photovoltaic frame.

[0025] In summary, compared with the prior art, the beneficial effects of this solution are: (1) The present invention arranges the mesh arc sleeve, the dust detector, the lever, the refraction plate and other structures, so that the detection end of the dust detector is facing downward and is not easily adhered to dust and dirt, and the detection accuracy can be improved. Under the condition of ensuring the gas flow efficiency, large particles and debris can be prevented from causing damage to the dust detector, so that the overall service life is effectively improved and the maintenance frequency is reduced; (2) The present invention uses the first spherical seat, the double-headed ball rod, the elastic arc plate and other structures to ensure that the photovoltaic frame is effectively tensioned and fixed by the first fastening belt, the second fastening belt and the winding shaft.

At the same time, the whole can absorb and alleviate vibration in harsh environments, so that the stability of the photovoltaic frame and the photovoltaic panel as a whole is effectively improved, and the service life of the whole equipment is effectively guaranteed; (4) The present invention provides a baffle, a rough panel, a first fixing nail and other structures, so that when the equipment is crawling, there is always a protective structure on the outside of the processing box and the crawling wheel, making the movement of the equipment safer. When the equipment is fixed, the processing box can be lifted upward away from the ground, making it difficult for moisture, insects, birds and animals to enter, effectively improving the service life of the inside of the processing box, reducing the number of maintenance times and ensuring the overall fixing effect.

[0026] (5) The present invention protects the control unit and power supply unit and the corresponding wires that are originally exposed to the outside through the arrangement of the storage tube and the processing box, so that they will not be easily damaged, thereby effectively improving the service life of the entire equipment.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Embodiment 1: Reference Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 , an online sampling and detection device for dust from civil construction. In order to facilitate the device to be effectively adapted to various construction sites, a base 10 and a processing box 39 are set. The processing box 39 is set on the bottom end surface of the base 10, and a power supply unit 40 is placed inside the processing box 39. The power supply unit 40 is a prior art, including a battery and a wiring port. The specific structure is not elaborated in this scheme. The power supply unit 40 is used to supply power to the entire device and store electricity. In this scheme, the heavier power supply unit 40 is placed in the processing box 39 at the bottom of the base 10, which can also make the overall weight of the device lighter. The center of gravity moves downward, which improves the stability of the entire equipment. At the same time, the equipment can also work normally for a short time when the external power is off. Multiple driving motors are arranged at both ends of the inside of the processing box 39. The output ends of the multiple driving motors extend out of the end face of the processing box 39. A detachable and replaceable crawler wheel 37 is arranged at one 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, thereby completing the rapid movement of the equipment. Support and reinforcement components are arranged on both sides of the processing box 39. When the equipment completes the movement, the support and reinforcement components can be used to fix the entire equipment.

[0030] A fixing seat 19 is provided at the upper end surface of the base 10, and a hollow column 11 is supported and fixed in the fixing seat 19. The interior of the hollow column 11 is hollow, and a placement cylinder 31 is connected to one end of the top of the hollow column 11. A control unit 41 is placed in the placement cylinder 31. Multiple detection components in the device are uniformly controlled and deployed by the control unit 41. This is a prior art, and this solution will not be elaborated on in detail. The upper end surface of the placement cylinder 31 is open, and a conical cover plate 24 is provided in cooperation with the internal thread, and the conical cover plate 24 can be used to place the placement cylinder 31. 1 is sealed, and the staff can also open the conical cover plate 24 to perform maintenance on the control unit 41 inside the storage cylinder 31. Since the interior of the hollow column 11 is hollow, the wires and signal lines required by the control unit 41 can be placed in the hollow column 11 and led downward to complete the wiring, thereby reducing the occurrence of flying wires and improving the overall safety of the equipment. In this relationship, the control panel 18 can be installed at any height outside the hollow column 11, so that the overall operation of the equipment can be controlled.

[0031] Reference Figure 1 and attached Figure 5 A detection platform 12 is fixedly arranged on the outer side of the top of the storage cylinder 31, and a dust detection component is arranged above the detection platform 12. The dust detection component can perform real-time detection and processing of the dust content in the air. A wind direction detector 23 is arranged on the end face of the detection platform 12 on one side of the dust detection component. The wind direction detector 23 is used to detect the flow direction of the wind. A wind speed detector 22 is arranged on the other side of the dust detection component and on the end face of the detection platform 12. The wind speed detector 22 can perform real-time monitoring and processing of the wind speed. In order 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, and a plurality of photovoltaic panels 14 are arranged on the end face of the photovoltaic frame 13. The plurality of photovoltaic panels 14 and the photovoltaic frame 13 can generate photovoltaic electricity and supply electricity to the equipment, so that the equipment can be used for a short time without being connected to an external power supply, so that the equipment can adapt to more complex construction environments and improve the scope of application.

[0032] For further information, see Attachment Figure 6 and attached Figure 7 The dust detection component includes a support frame 34 fixed on the end face of the detection platform 12, an annular plate 32 is fixedly arranged in the middle of the support frame 34, and a mesh arc sleeve 33 made of flexible rubber material is arranged on the bottom end face of the annular plate 32, the bottom of the mesh arc sleeve 33 is open, the middle part is arc-shaped, and a plurality of grid holes for dust gas flow are arranged on the middle arc surface of the mesh arc sleeve 33, and a dust detector 49 is arranged on the end face of the annular plate 32 in the middle of the mesh arc sleeve 33, and the detection end of the dust detector 49 faces downward. In this scheme, the dust detector 49 is based on the principle of light scattering, and emits a light beam through an LED lamp or a laser. When particles in the air enter the light beam, the light beam will be scattered on the particles. At this time, the detection end on the dust detector 49 determines the concentration and particle size of the particles by detecting the intensity and angle of the scattered light. The mesh arc sleeve 33 is arranged on the outside of the dust detector 49, which can filter and block large particles of sand and gravel debris in the air, prevent large particles of sand and gravel debris from damaging the dust detector 49, and increase the service life of the dust detector 49. At the same time, the detection end of the dust detector 49 is facing downward, which reduces the accumulation of dust and dirt at the detection end compared to the traditional upward arrangement, and can extend the use time after a single maintenance to a certain extent. The bottom of the mesh arc sleeve 33 is open as a whole, which is convenient for gas flow and the filtered particulate dirt can also fall quickly, reducing the accumulation inside the mesh arc sleeve 33.

[0033] For further information, see Attachment Figure 6 and attached Figure 7In order 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 and arranged in the support frame 34 below the mesh arc sleeve 33, and a dust removal motor 53 is fixedly arranged on the upper end surface of the support plate 52. A connecting plate 47 is connected and arranged on the output end surface of the dust removal motor 53. A plurality of levers 48 are connected and arranged on the outer circumferential surface of the connecting plate 47 along the circumferential direction. The plurality of levers 48 are arc-shaped and fit on the outside of the mesh arc sleeve 33. The arc surface of the mesh arc sleeve 33 is roughened when the levers 48 fit on the arc surface of the outside of the mesh arc sleeve 33. When the mesh arc sleeve 33 is used for a long time, the grid holes The dust particles are easily blocked on the mesh surface. At this time, the output end of the dust removal motor 53 can drive the connecting plate 47 to rotate, thereby driving the multiple levers 48 to rotate. The levers 48 in the rotating state will continuously scrape the outer surface of the mesh arc sleeve 33, thereby scraping off the dust and dirt accumulated on the grid holes of the mesh arc sleeve 33. In this solution, the levers 48 are woven from elastic metal wires, which have a certain toughness and elasticity. When scraping the outer surface of the mesh arc sleeve 33, when encountering particle protrusions, they can generate moving jitters, thereby bouncing the particle dust so that it can fall smoothly, completing the cleaning process; In the present solution, in order 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. It is a prior art that the conical surface is made to ensure that the fallen dust and dirt can be discharged smoothly. A certain gap is left between the refraction plate 50 and the mesh arc sleeve 33 for the discharge of dust and dirt. A rotating coupling 51 is rotatably connected in the middle between the refraction plate 50 and the connecting disk 47. When the connecting disk 47 rotates, the rotating coupling 51 and the refraction plate 50 will not rotate because the rotating coupling 51 rotates with the connecting disk 47. Therefore, the rotating coupling 51 and the refraction plate 50 will not rotate, so that the refraction plate 50 can be lifted below the mesh arc sleeve 33 but will not block the bottom opening of the mesh arc sleeve 33, thereby ensuring the refraction efficiency and improving the dust removal efficiency.

[0034] For further information, see Attachment Figure 1 , Attachment Figure 2 and attached Figure 3 A bracket 25 is fixedly provided on both sides of the upper end surface of the detection table 12, and a first rotating seat 29 is fixedly provided on the upper end surface of the bracket 25. A rotating block 30 is rotatably provided 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 with the rotating connection point between the two rotating blocks 30 and the first rotating seat 29 as the center of the circle, so that the photovoltaic frame 13 can adjust the angle according to the rise and fall of the sun in a sunny environment, so that multiple photovoltaic panels 14 can generate electricity better. A sensor for sensing light sources is provided on the photovoltaic frame 13, which is used to sense the light source. It is a prior art and will not be elaborated in this scheme.

[0035] Reference Figure 8 , Attachment Fig. 9 and attached Fig.10 Two second supports 36 are fixedly arranged on both sides of one side of the bottom of the detection platform 12, and a winding shaft 55 is rotatably arranged in the two second supports 36. A motor capable of automatic locking is arranged on the outside of the second support 36 on one side of the winding shaft 55, and the output end of the motor is connected to the end surface of the winding shaft 55. A second fastening belt 68 is wound on the outer circumferential surface of the winding shaft 55, and one end of the second fastening belt 68 is connected to one end of the bottom of the photovoltaic frame 13. A first support 21 is fixedly arranged on the bottom end surface of the detection platform 12 on one side of the second support 36, and a barrel 20 is fixedly arranged in the first support 21. A torsion spring shaft 54 ​​is rotatably arranged in the barrel 20, and both ends of the torsion spring shaft 54 ​​are connected to torsion springs 67 in the barrel 20. A first fastening belt 26 is also wound on the outer circumferential surface of the torsion spring shaft 54. The other end of the first fastening belt 26 is connected to the bottom end of the photovoltaic frame 13 after extending out of the barrel 20. Therefore, the two winding shafts 55 and the first fastening belts 26 and the second fastening belts 68 wound on the two torsion spring shafts 54 form a mutually pulling state at the bottom of the photovoltaic frame 13. In this solution, the first fastening belt 26 and the second fastening belt 68 are both flexible metal wires inside and non-slip rubber layers outside, and have certain strength and toughness; Therefore, when the photovoltaic frame 13 needs to rotate an angle, the motor on one side of the second support 36 will drive the winding shaft 55 to rotate clockwise or counterclockwise, thereby driving the second fastening belt 68 on the outside of the winding shaft 55 to reel in or unwind, thereby pulling the photovoltaic frame 13 as a whole to tilt downward toward one side of the winding shaft 55 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 on the outside of the torsion spring shaft 54 ​​will also be released outward, so that the torsion springs 67 on both sides of the torsion spring shaft 54 ​​are stressed, Tension will be formed at the raised end of the photovoltaic frame 13, thereby improving the overall fixing effect of the photovoltaic frame 13. When the photovoltaic frame 13 needs to be rotated toward the torsion spring shaft 54, the winding shaft 55 will be unwound, and the torsion springs 67 on both sides of the torsion spring shaft 54 ​​will also release pressure to drive the torsion spring shaft 54 ​​to rotate, so that the first fastening belt 26 on the outside of the torsion spring shaft 54 ​​can be rolled inward, so that the photovoltaic frame 13 can be smoothly flipped. 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 accompanying drawings will not show it in detail.

[0036] For further information, see Attachment Figure 8 , Attachment Fig. 9 and attached Fig.10In order to ensure the stability of the photovoltaic frame 13, an inclined pushing cylinder 57 is fixedly arranged at the bottom of the inspection table 12 on one side of the second support 36. The pushing cylinder 57 is an electrically driven cylinder body. A clamping head 58 is connected to the output end of the pushing 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 non-slip rubber material with a roughened surface. When the photovoltaic frame 13 completes the angle adjustment, the output end of the pushing cylinder 57 will push the clamping head 58 to move outward, thereby pushing the limit block 56 at one end of the clamping head 58 to abut against the outer circumferential surface of the second fastening belt 68 wound around the outside of the coil shaft 55, so that the second fastening belt 68 can be clamped and fixed, so that the second fastening belt 68 outside the coil shaft 55 is not The method continues to pull, so that the photovoltaic frame 13 at one end of the second fastening belt 68 is fixed. In this solution, when strong winds appear outside, the winding shaft 55 in the second support 36 will completely reel the second fastening belt 68 inward, so that the photovoltaic frame 13 as a whole is completely tilted toward the side of the winding shaft 55, and then the pushing cylinder 57 will also increase the pressure of the power pressure limit block 56 and the second fastening belt 68 winding material, so that the overall stability of the photovoltaic frame 13 is improved, and the durability of the photovoltaic frame 13 in a harsh environment with strong winds is improved, and damage is reduced. At the same time, the overall tilting of the photovoltaic frame 13 can also protect multiple detection parts on the end face of the detection platform 12, and can also reduce damage to the detection parts on the end face of the detection platform 12, thereby increasing the overall service life of the equipment.

[0037] Embodiment 2: Reference Fig.11 , Attachment Fig.12 , Attachment Fig.13 and attached Fig.14, an online sampling and detection device for dust in civil construction, the supporting and reinforcing components include first opening holes 27 arranged on both sides of the processing box 39 on the end surface of the base 10, a baffle 15 is arranged to slide up and down in the first opening hole 27, a rough panel 16 is arranged on the bottom end surface of the baffle 15, the bottom of the rough panel 16 is roughened as a whole, a plurality of detachable first fixing nails 59 are arranged on one side of the bottom end surface 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 equipment is crawling, the baffle 15 and the rough panel 16 will move upward so that the bottom end surface of the rough panel 16 will not contact the ground, so that the equipment can crawl smoothly, but the baffle 15 and the rough panel 16 will block the outside of the crawling wheel 37 as a whole, so as to protect the crawling wheel 37 and reduce the possibility of damage to the crawling wheel 37 When the equipment stops moving, the baffle 15 and the rough panel 16 will move downward, and then the bottom of the rough panel 16 will be pressed on the ground as a whole. Then, the rough panel 16 will continue to move downward, and the base 10 will be propped up as a whole, so that the crawling wheel 37 and the processing box 39 are away from the ground. The baffle 15 will still block the outside of the processing box 39 and the crawling wheel 37 and protect them until the rough panel 16 is fixed. This setting can ensure that the crawling wheel 37 and the processing box 39 are less likely to be damaged by collision, so that the service life of the whole equipment is improved. Keeping the processing box 39 away from the ground can reduce the moisture on the ground or other insects, birds and animals from entering the processing box 39, so that the power supply or control structure in the processing box 39 can operate stably, improve the service life, reduce the number of maintenance times, and can be better applied to complex construction environments. The first fixing nail 59 and the second fixing nail 60 on the bottom of the rough panel 16 are set according to actual conditions. The first fixing nail 59 is shorter as a whole and is suitable for short-term fixation, while the second fixing nail 60 is long and strong as a whole and is suitable for long-term fixation.

[0039] 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 both sides to swing forward or backward. The rotating rod 17 will rotate around the rotating bearing 66, thereby driving one end of the bottom to tilt upward or tilt downward, thereby driving the second rotating seat 38 to move up and down, thereby driving the rough panel 16 and the baffle 15 to complete the up and down movement. In this solution, when the rotating rod 17 is centered and vertical, the rough panel 16 completes the support and fixed state.

[0040] Embodiment three: Reference Fig.12 , Attachment Fig.13 and attached Fig.14 , an online sampling and detection device for dust from civil construction, a fixing bolt 62 is fixedly arranged on one side of the outer end surface of the rotating rod 17 extending out of the base 10, a fixing bolt 62 is slidably arranged in the fixing bolt 62, and a bolt hole 65 is arranged on the end surface of the base 10 below the fixing bolt 62. When the rough panel 16 completes the support and fixation, the rotating rod 17 is in a 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, so that the rotating rod 17 can be fixed, so that the rotating rod 17 will not shake, so that the baffle 15 below the rotating rod 17 and the rough panel 16 are fixed as a whole, so that the equipment as a whole is effectively fixed.

[0041] Furthermore, a connector 64 is provided on one side wall of the handle 35 and on the end face of the base 10, and a connector 63 can be connected to the outside of the connector 64 by means of a thread. Threaded seats are provided at both ends of the connector 63, and a rigid rope is connected between the two threaded seats to form the connector 63. When the rough panel 16 needs to move outward, the fixing bolt 62 is unfastened and fixed from the bolt hole 65, and then the staff can tilt and swing the rotating rod 17 so that the rotating rod 17 tilts toward the end with the connector 64, so that the rough panel 16 moves upward, and then the staff can connect the two ends of the connector 63 to the two connectors 64, thereby fixing the rotating rod 17, so that the rotating rod 17 will be in a tilted state for a long time under the tension and fixation of the connector 63, so that the rough panel 16 will not contact the ground at all times when the device moves, so that the device can move smoothly.

[0042] Embodiment 4: Reference Figure 6 and attached 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.

[0043] 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.
