Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of gas analysis and detection instruments, and specifically to a multifunctional gas analysis and detection instrument. Background Art
[0002] Gas analysis and detection instruments are devices used to monitor the composition and concentration of gases in the environment. They are widely used in industrial safety, environmental monitoring, laboratory research, and other fields. Traditional gas detectors are typically fixed or handheld designs, capable of sampling and analyzing gases at specific locations.
[0003] In practical applications, especially in complex environments (such as high altitude, narrow space or multi-point monitoring scenarios), lateral movement mostly relies on manual slides or simple motor drives, which lack buffer protection and stroke limit functions and are easily damaged by collision; longitudinal adjustment often uses electric push rods or rope traction, which have high energy consumption and cannot maintain position after power failure, resulting in poor repeat positioning accuracy. Some detectors rely on manual operation and it is difficult to achieve automatic precise positioning. Therefore, a multifunctional gas analysis and detection instrument is provided to solve the above problems. Summary of the Invention
[0004] In order to solve the above problems, the present invention provides a multifunctional gas analysis and detection instrument to solve the above problems.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] A multifunctional gas analysis and detection instrument comprises a gas analysis and detection instrument body, a transverse adjustment member is provided above the gas analysis and detection instrument body, a transverse and longitudinal connecting member is mounted on the transverse adjustment member, and a longitudinal adjustment member is connected to the bottom of the transverse and longitudinal connecting member;
[0007] Wherein, the main body of the gas analysis detector is slidably connected to the front side of the longitudinal adjustment member.
[0008] Furthermore, the lateral adjustment member includes a slide rail, and wall positioning frames are installed on both sides of the slide rail. A threaded rotating rod is rotatably connected between the two wall positioning frames, and a first servo motor is installed on one of the wall positioning frames. The output shaft of the first servo motor is connected to the adjacent threaded rotating rod through a coupling.
[0009] Furthermore, a first buffer plate is provided on one adjacent side of the two wall positioning frames, and the two first buffer plates are connected to a first buffer spring, and the two first buffer plates are connected to the adjacent wall positioning frames through the first buffer spring.
[0010] Furthermore, the horizontal and vertical connecting parts include a base plate, a threaded ring is installed on the top of the base plate, the threaded ring is threadedly connected to the threaded rotating rod, and a first limiting slider is also installed on the top of the base plate, and the base plate is slidably connected to the slide rail through the first limiting slider.
[0011] Furthermore, a limiting frame is installed on the top of the base plate, a stop plate is inserted into the limiting frame, a positioning bolt is threadedly connected to the top of the limiting frame, and the bottom end of the positioning bolt passes through the limiting frame and fits and positions with the top of the stop plate.
[0012] Furthermore, the top end of the longitudinal adjustment member is inserted into the bottom plate, and two positioning blocks are provided on the bottom plate. The two positioning blocks pass through the longitudinal adjustment member and are inserted into the adjacent bottom plate.
[0013] Furthermore, the longitudinal adjustment member includes a support rod, an adjustment tooth is installed on the side of the support rod, and a sliding groove is provided on the support rod;
[0014] A second servo motor is installed on the top of the gas analysis and detection instrument body, and the output shaft of the second servo motor is connected to the driving gear through a coupling, and the driving gear is engaged with each other. A second limiting slider is also installed on the gas analysis and detection instrument body, and the second limiting slider is slidably connected to the slide groove.
[0015] Furthermore, a second buffer plate is slidably connected to the bottom of the support rod, and two second buffer springs are installed on the second buffer plate. The two second buffer springs are both connected to the bottom of the support rod.
[0016] Furthermore, a temporary limit block is rotatably connected inside the support rod, and a torsion spring is provided at the rotation connection portion between the temporary limit block and the support rod. The temporary limit block is kept tilted relative to the support rod by the torsion spring.
[0017] Furthermore, there are ten support rods, and the distance between two adjacent support rods is greater than the thickness of the second limiting sliding block.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. This gas analysis and detection instrument achieves multi-dimensional precise positioning of environmental gas sampling through an innovative mechanical structure and intelligent adjustment system. Its core advantage is reflected in the lateral adjustment system: it adopts a mechanical transmission method in which a servo motor drives a threaded rotating rod, combined with the dual guidance of the slide rail and the limit slider, to ensure that the main body of the detector can move smoothly in the horizontal direction. The unique combination design of the buffer device (first buffer plate + spring) and the adjustable limit mechanism (resistance plate + positioning bolt) not only realizes flexible buffer protection at the end point of movement, but also allows users to customize the travel range according to actual needs. The entire lateral adjustment system can be quickly installed through a wall positioning bracket, and the lowest position design ensures that the equipment never touches the ground, significantly improving the safety and adaptability of field operations.
[0020] 2. In terms of longitudinal adjustment, the instrument adopts an innovative design of gear meshing transmission and temporary self-locking. The servo motor drives the active gear to drive the adjustment rack up and down, and cooperates with the sliding structure of the support rod and the limit slider to form a stable vertical motion system. The specially designed temporary limit block mechanism uses a torsion spring to achieve gravity self-balancing. It can not only automatically lock the height position when the power is off, but also easily unlock and continue to adjust through the motor torque. This mechanical self-locking mechanism is more energy-efficient and reliable than pure electric maintenance. The entire system uses a modular design to achieve rapid assembly of horizontal and vertical components (fixed by positioning plugs), so that the equipment has both millimeter-level positioning accuracy and kilogram-level load capacity, which is perfectly adapted to the needs of multi-point gas sampling in complex environments.

[0028] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0029] Reference Figure 1-5 A multifunctional gas analysis and detection instrument includes a gas analysis and detection instrument body 4, a transverse adjustment member 1 is provided above the gas analysis and detection instrument body 4, a transverse and longitudinal connecting member 2 is installed on the transverse adjustment member 1, and a longitudinal adjustment member 3 is connected to the bottom of the transverse and longitudinal connecting member 2;
[0030] Among them, the gas analysis detector body 4 is slidingly connected to the front of the longitudinal adjustment member 3, and the transverse adjustment member 1 includes a slide rail 11. Wall positioning frames 14 are installed on both sides of the slide rail 11. A threaded rotating rod 13 is rotatably connected between the two wall positioning frames 14, and a first servo motor 12 is installed on one of the wall positioning frames 14. The output shaft of the first servo motor 12 is connected to the adjacent threaded rotating rod 13 through a coupling. A first buffer plate 15 is provided on the adjacent side of the two wall positioning frames 14, and the two first buffer plates 15 are connected to the first buffer spring 16. The two first buffer plates 15 are connected to the adjacent wall positioning frames 14 through the first buffer spring 16.
[0031] Specifically, when the horizontal position needs to be adjusted, the wall positioning frame 14 and the slide rail 11 have been fixed, and then the first servo motor 12 is started to drive the threaded rotating rod 13 to rotate. Under the limit of the slide rail 11 and the first limit slider 26, the threaded ring 22 on the base plate 21 will drive the entire horizontal and vertical connecting parts 2 to move left and right along the direction of the threaded rotating rod 13 when the threaded rotating rod 13 rotates, thereby realizing the adjustment of the horizontal position of the gas analysis detector body 4.
[0032] As an optimization solution, the horizontal and vertical connecting members 2 include a base plate 21, a threaded ring 22 is installed on the top of the base plate 21, and the threaded ring 22 is threadedly connected to the threaded rotating rod 13. A first limit slider 26 is also installed on the top of the base plate 21, and the base plate 21 is slidably connected to the slide rail 11 through the first limit slider 26. A limit frame 23 is installed on the top of the base plate 21, and a back plate 24 is inserted into the limit frame 23. The top of the limit frame 23 is threadedly connected with a positioning bolt 25, and the bottom end of the positioning bolt 25 passes through the limit frame 23 and is positioned in contact with the top of the back plate 24. The top end of the longitudinal adjustment member 3 is inserted into the base plate 21, and two positioning blocks 27 are provided on the base plate 21. The two positioning blocks 27 pass through the longitudinal adjustment member 3 and are inserted into the adjacent base plate 21.
[0033] Specifically, the first buffer plate 15 and the first buffer spring 16 can also cooperate with the abutment plate 24 to limit the maximum movement position of the gas analysis detector body 4. When the abutment plate 24 contacts the first buffer plate 15, the first buffer spring 16 will compress and buffer. At this time, the first servo motor 12 can be stopped, and the position of the abutment plate 24 can be adjusted by turning and loosening the positioning bolt 25 to limit the left and right movement lengths of the horizontal and vertical connecting member 2 as needed. After adjustment, the positioning bolt 25 can be tightened.
[0034] Furthermore, the connection between the transverse and longitudinal connecting members 2 and the longitudinal adjusting member 3 can be achieved by first inserting the support rod 31 into the bottom plate 21 and then fixing the support rod 31 and the bottom plate 21 stably through the positioning insert 27 .
[0035] The longitudinal adjustment member 3 includes a support rod 31, an adjustment tooth 32 is installed on the side of the support rod 31, and a sliding groove 34 is opened on the support rod 31;
[0036] A second servo motor 41 is installed on the top of the gas analysis detector body 4. The output shaft of the second servo motor 41 is connected to a driving gear 42 through a coupling. The driving gear 42 is meshed with the driving gear 42. A second limiting slider 42 is also installed on the gas analysis detector body 4. The second limiting slider 42 is slidably connected to the slide groove 34.
[0037] The bottom of the support rod 31 is slidably connected to a second buffer plate 35, and two second buffer springs 33 are installed on the second buffer plate 35. The two second buffer springs 33 are both connected to the bottom of the support rod 31. The internal rotation of the support rod 31 is connected to a temporary limit block 36. The rotation connection part between the temporary limit block 36 and the support rod 31 is provided with a torsion spring. The temporary limit block 36 is kept inclined to the support rod 31 by the torsion spring. There are ten support rods 31, and the distance between two adjacent support rods 31 is greater than the thickness of the second limit slider 42.
[0038] Specifically, starting the second servo motor 41 to drive the active gear 42 can make the gas analysis detector body 4 rise or fall under the meshing of the active gear 42 and the adjusting gear 32, and in this process, the sliding connection between the support rod 31 and the second limit slider 42 can support the meshing and sliding of the active gear 42 and the adjusting gear 32, and the lifting and lowering adjustment can be adjusted as needed;
[0039] After adding the temporary limit block 36, the second servo motor 41 can be turned off after the height of the gas analysis detector body 4 is adjusted, so that the second limit slider 42 is blocked by the temporary limit block 36 when it falls. The force of the torsion spring between the temporary limit block 36 and the support rod 31 can support the gravity of the gas analysis detector body 4 and prevent the gas analysis detector body 4 from falling. When it needs to move downward, the second servo motor 41 can work to overcome the elastic force of the torsion spring between the support rod 31 and the temporary limit block 36.
[0040] Working principle: When the device is in use, it uses the gas analysis detector body 4 to collect specific environmental information. Before adjustment, the slide rail 11 and the wall positioning bracket 14 can be fixed at the corresponding positions that need to be fixed using screws. They can be temporarily supported by a support frame or a wall, etc., to keep the gas analysis detector body 4 from touching the ground when it runs to the lowest point;
[0041] However, when collecting gas environment, it is impossible to collect gas from only one point, so adjustment is required;
[0042] When the lateral position needs to be adjusted, the wall positioning bracket 14 and the slide rail 11 are already fixed, and then the first servo motor 12 is started to drive the threaded rotating rod 13 to rotate. Under the limit of the slide rail 11 and the first limit slider 26, the threaded ring 22 on the bottom plate 21 will drive the entire horizontal and vertical connecting member 2 to move left and right along the direction of the threaded rotating rod 13 when the threaded rotating rod 13 rotates, thereby achieving the adjustment of the lateral position of the gas analysis detector body 4;
[0043] During the adjustment process, the first buffer plate 15 and the first buffer spring 16 can also cooperate with the abutment plate 24 to limit the maximum movement position of the gas analysis detector body 4. When the abutment plate 24 contacts the first buffer plate 15, the first buffer spring 16 will compress and buffer. At this time, the first servo motor 12 can be stopped, and the position of the abutment plate 24 can be adjusted by turning and loosening the positioning bolt 25. The different lengths of left and right movement of the horizontal and vertical connecting member 2 can be limited as needed. After adjustment, the positioning bolt 25 can be tightened.
[0044] The connection between the horizontal and vertical connecting member 2 and the longitudinal adjusting member 3 can be achieved by first inserting the support rod 31 into the bottom plate 21 and then fixing the support rod 31 and the bottom plate 21 stably through the positioning plug 27;
[0045] When the longitudinal position needs to be adjusted, the second servo motor 41 is started to drive the active gear 42 so that the gas analysis detector body 4 can be raised or lowered under the meshing of the active gear 42 and the adjusting gear 32. In this process, the sliding connection between the support rod 31 and the second limit slider 42 can support the meshing and sliding of the active gear 42 and the adjusting gear 32, so as to adjust the height as needed;
[0046] After adding the temporary limit block 36, the second servo motor 41 can be turned off after the height of the gas analysis detector body 4 is adjusted, so that the second limit slider 42 is blocked by the temporary limit block 36 when it falls. The force of the torsion spring between the temporary limit block 36 and the support rod 31 can support the gravity of the gas analysis detector body 4 and prevent the gas analysis detector body 4 from falling. When it needs to move downward, the second servo motor 41 can work to overcome the elastic force of the torsion spring between the support rod 31 and the temporary limit block 36.
[0047] Practical usage of the device:
[0048] The gas analysis and detection instrument needs to be installed and positioned before use. First, fix the slide rail 11 assembly to a supporting surface such as a wall or a bracket through the wall positioning bracket 14 to ensure that it is firmly installed. During installation, it is necessary to adjust the height so that the main body 4 of the gas analysis and detection instrument can still maintain a safe distance from the ground when it is in the lowest operating position. After completing the mechanical fixation, it is necessary to check whether all electrical connections are normal, including the connection of the power supply lines and the control system of the first servo motor 12 and the second servo motor 41. After the installation is completed, the main body 4 of the gas analysis and detection instrument should be initialized and calibrated to ensure the accuracy of the gas collection data.
[0049] When the horizontal position of the detector needs to be adjusted, the first servo motor 12 is activated through the control system. The motor drives the threaded rotating rod 13 to rotate, driving the threaded ring 22 on the base plate 21 to move along the slide rail 11. During the movement, the first limit slider 26 cooperates with the slide rail 11 to ensure smooth movement. The user can set the limit of lateral movement by adjusting the position of the abutment plate 24 according to actual needs. When the detector moves to the set position, the buffer device composed of the first buffer plate 15 and the first buffer spring 16 automatically absorbs the impact force. After the position adjustment is completed, the system automatically locks the current position to ensure stability during the detection process.
[0050] The vertical position is adjusted by driving the gear transmission system through the second servo motor 41. After starting the motor, the active teeth 42 engage with the adjustment teeth 32, driving the main body 4 of the gas analysis detector to rise and fall along the support rod 31. During the lifting process, the second limit slider 42 ensures the linearity of the motion trajectory. The specially designed temporary limit block 36 mechanism can achieve a self-locking function at any height. When the target height is reached, the detector can still maintain a stable position even if the motor is turned off. If you need to continue adjusting, you only need to restart the second servo motor 41 to overcome the elastic force of the torsion spring between the temporary limit block 36 and the support rod 31 to achieve smooth and continuous adjustment.
[0051] During the actual sampling process, the lateral and longitudinal adjustment functions can be combined to achieve multi-point sampling in three-dimensional space. The system supports programming control of preset sampling paths and can automatically complete continuous sampling of a series of points. After each use, the sampling port of the gas analysis detector body 4 should be cleaned, and the lubrication condition of each moving part should be checked regularly. When not in use for a long time, it is recommended to move the detector to its initial position and disconnect the power supply. When maintaining the system, special attention should be paid to the inspection of buffer devices such as the first buffer plate 15, the first buffer spring 16 and the second buffer spring 33, as well as the self-locking mechanism of the temporary limit block 36 to ensure their normal performance.
