Description

Technical Field

[0001] The present invention relates to the technical field of gas detection, and in particular to a multi-mode fusion portable intelligent gas detector and method. Background Art

[0002] A gas detector is an instrument used to detect the concentration of various gases in the air. It is mainly used to determine whether the air quality meets the standards. Gas detectors are widely used in industries, mining, environmental monitoring, laboratories, fire protection and other fields.

[0003] Existing gas detectors use a variety of methods to detect gas, such as a portable gas detector with a publication number of CN115078649A, which relates to the technical field of detection instruments. The portable gas detector includes a shell, a detection component and a portable component. The shell itself cooperates to enclose a containing chamber; the detection component includes a detection chamber and a sensor unit arranged in the detection chamber, the detection chamber is defined by a detection inner wall arranged in the containing chamber, and the detection chamber has an air inlet and an exhaust port, and a one-way valve is arranged at the exhaust port; the portable component includes a fixed platform and a ring member detachably connected to the fixed platform, and the fixed platform and the shell are fixedly connected or integrally formed.

[0004] When using existing gas detectors, operators usually need to hold the detector and place it in the detection area to inhale. This inhalation method is limited by the length of the operator's arm, which makes the detector's movement position limited, the detection area small, and it is impossible to achieve multi-mode synchronous detection at the same time;

[0005] For example, the prior art referred to above requires the operator to place the detector in the target area for inhalation and detection when the device is in use, which is cumbersome to operate and has a limited detection area. At the same time, the detection sensors in the device are all arranged in the same detection chamber. In order to avoid mutual influence between multiple detection sensors, only one gas can be detected each time when inhaling, and multiple gases cannot be accurately detected simultaneously. The detection efficiency is low and has certain limitations.

DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0055] Example 1: Reference Figure 1-Figure 2 A multi-mode fusion portable intelligent gas detector includes a detector body 1, and a detection handle 3 is fixedly installed on the side of the detector body 1. The detection handle 3 is used to realize the portable movement of the detector body 1, and the detection handle 3 is used to realize the rapid movement of the detector body 1, thereby realizing gas detection in multiple positions and multiple areas.

[0056] The detector also includes:

[0057] The elastic air inlet pipe 4 is arranged outside the detector body 1 and is used to absorb the external gas to be detected. The elastic air inlet pipe 4 can be extended and contracted, so that the position of its air inlet end can be flexibly adjusted, and then the air inlet detection is performed on different areas, thereby improving the overall detection range;

[0058] The air collection unit is arranged in the detector body 1, and is used to quickly suck the air in the area to be detected into the detector body 1 for detection, and the position and range of the air suction can be flexibly adjusted according to the detection requirements, thereby effectively improving the detection efficiency;

[0059] The detection unit is arranged in the detector body 1. The detection unit is used to evenly conduct and partition the air sucked in by the gas collection unit, and independently detect the air in different partitions, thereby realizing the simultaneous detection of multiple gas components and effectively improving the detection efficiency.

[0060] A control panel 2 is provided on the upper part of the detector body 1, and the opening and closing and operating states of the gas collection unit and the detection unit are controlled by the control panel 2 to realize automatic intelligent gas detection;

[0061] Example 2: Reference Figure 2-Figure 7 The technical solution of this embodiment is different from that of the first embodiment in that the gas collection unit includes an adjustment component and an air suction component, wherein the adjustment component is used to adjust the end position of the elastic air inlet pipe 4 to achieve multi-point targeted air suction, and the air suction component is used to suck the gas into the detector body 1 through the elastic air inlet pipe 4;

[0062] The air suction component includes a servo motor 8 fixedly installed in the detector body 1, a driving roller 13 is fixedly installed on the driving end of the servo motor 8, an air guide box 9 is fixedly installed on the detector body 1, and the air guide box 9 is connected to the elastic air inlet pipe 4, so that the air in the elastic air inlet pipe 4 can directly enter the air guide box 9. When the servo motor 8 is started, it will drive the driving roller 13 to rotate forward or reverse.

[0063] An air blowing mechanism is installed between the air guide box 9 and the driving roller 13, and the air blowing mechanism includes a one-way bearing rod 31 arranged on the driving roller 13, and the one-way bearing rod 31 rotates forward synchronously under the driving of the forward rotation of the driving roller 13, a reciprocating screw rod 14 is fixedly installed on the one-way bearing rod 31, and a ball nut plate 24 is matched with the reciprocating screw rod 14, a reciprocating air suction plate 21 is slidably installed in the air guide box 9, and a linkage rod 33 is fixedly installed between the reciprocating air suction plate 21 and the ball nut plate 24;

[0064] When the air is sucked, the servo motor 8 is started to drive the driving roller 13 to rotate in the forward direction. When the driving roller 13 rotates in the forward direction, the one-way bearing rod 31 is driven to rotate (when the driving roller 13 rotates in the reverse direction, the one-way bearing rod 31 does not rotate). When the one-way bearing rod 31 rotates, the reciprocating screw rod 14 is driven to rotate.

[0065] The reciprocating screw 14 cooperates with the ball nut plate 24, so that when the reciprocating screw 14 rotates, it will drive the ball nut plate 24 to move back and forth on the reciprocating screw 14. When the ball nut plate 24 moves to the right, it will drive the reciprocating air suction plate 21 to move to the right in the air guide box 9 through the linkage rod 33. When the ball nut plate 24 moves to the left, it will drive the reciprocating air suction plate 21 to move to the left in the air guide box 9 through the linkage rod 33. The reciprocating screw 14 rotates continuously to realize the reciprocating left and right movement of the reciprocating air suction plate 21 in the air guide box 9.

[0066] The cooperation between the reciprocating screw 14 and the ball nut plate 24 is a prior art, and the specific principle is as follows: the reciprocating screw 14 is a form of a three-dimensional cam pair, which is represented by two thread grooves with the same pitch and opposite rotation directions. The two ends of the screw are connected by a transition curve. Through the rotation of the screw, the side of the spiral groove pushes the ball placed in the spiral groove of the ball nut plate 24 to make axial reciprocating motion, thereby driving the ball nut plate 24 to reciprocate, that is, when the reciprocating screw 14 rotates unidirectionally, it can drive the ball nut plate 24 to make reciprocating linear motion on the reciprocating screw 14;

[0067] This part is the prior art and will not be described in detail here.

[0068] When the reciprocating air intake plate 21 moves to the left in the air guide box 9, the space on the right side of the reciprocating air intake plate 21 in the air guide box 9 can be increased, and the external air to be detected can be sucked into the air guide box 9 through the elastic air inlet pipe 4. When the reciprocating air intake plate 21 moves to the right, the gas sucked into the air guide box 9 can be automatically pressed out.

[0069] In a further embodiment, the adjustment assembly includes a moving ring 15 and a positioning ring 16 fixedly mounted at both ends of the elastic air inlet pipe 4, and a push spring rod 6 is fixedly mounted between the moving ring 15 and the positioning ring 16, and the push spring rod 6 is in a compressed state in the initial state;

[0070] A mounting frame 17 is fixedly mounted on the positioning ring 16, and a traction roller 18 is rotatably mounted on the mounting frame 17, and a traction rope 7 is fixedly connected between the traction roller 18 and the moving ring 15, a telescopic rocker 5 is rotatably mounted on the traction roller 18, a positioning pin 19 is fixedly mounted on the telescopic rocker 5, and a plurality of positioning holes 20 matching the positioning pin 19 are opened on the mounting frame 17;

[0071] When the length of the elastic air inlet pipe 4 needs to be increased, the telescopic rocker 5 can be pulled out first to drive the positioning pin 19 to move outward, so that the positioning pin 19 is separated from the positioning hole 20, thereby releasing the positioning of the telescopic rocker 5 and the traction roller 18, and then the telescopic rocker 5 is rotated to drive the traction roller 18 to rotate and release the traction rope 7. At this time, the push spring rod 6 will automatically extend when the tension is reduced, thereby driving the moving ring 15 to move away from the positioning ring 16. When the moving ring 15 moves, it will drive the elastic air inlet pipe 4 to move and extend it as a whole;

[0072] When the position of the elastic air inlet pipe 4 is adjusted, the telescopic rocker 5 can be pressed to drive the positioning pin 19 to move so that it is engaged with the positioning pin hole 20 in the mounting frame 17, and the traction roller 18 can be limited so that it cannot continue to rotate, that is, the traction rope 7 cannot be released further, thereby achieving the length limitation of the elastic air inlet pipe 4.

[0073] When the length of the elastic air inlet pipe 4 needs to be reduced, the telescopic rocker 5 only needs to be rotated in the opposite direction to drive the traction roller 18 to reversely reel in the traction rope 7, and the moving ring 15 can be directly pulled back by the traction rope 7, and then the elastic air inlet pipe 4 can be compressed by the moving ring 15 to shrink it, so as to shorten the elastic air inlet pipe 4;

[0074] Through the above operation, the length of the elastic air inlet pipe 4 can be flexibly controlled so that it can be moved to different areas and different environments for air inhalation, thereby effectively increasing the air inhalation range of the detector and improving the detection range of the detector.

[0075] Example 3: Reference Figure 2-Figure 5 as well as Figure 8-Figure 15 The technical solution of this embodiment is different from that of the second embodiment in that: the gas collection unit includes a partition detection component and a gas guide component, wherein the partition detection component is provided with a plurality of gas detection sensors 26, and the plurality of gas detection sensors 26 have different functions and can perform targeted inhalation detection on the content of different gas components in the air;

[0076] When the gas detection sensor 26 is started, it absorbs the air in the surrounding environment into the interior thereof by natural diffusion, and performs gas detection on the inhaled air through its internal components.

[0077] The partition detection component is used to partition the inhaled gas and perform multi-component detection on the partitioned gas through multiple gas detection sensors 26. The gas guide component is used to realize the introduction and complete removal of the gas in the partition detection component.

[0078] The partition detection assembly includes a plurality of detection boxes 10 fixedly mounted on the air guide box 9, each detection box 10 is fixedly connected to a gas distribution square tube 22, and each gas distribution square tube 22 is slidably connected to the reciprocating air suction plate 21;

[0079] When the reciprocating air suction plate 21 moves to the right, the air sucked into the air guide box 9 can be pressed into multiple air distribution square tubes 22, and the corresponding air can be injected into the detection box 10 through the air distribution square tubes 22, so as to complete the zoning storage of the air, and the whole air is divided into three parts and transmitted to the three detection boxes 10, and the air content in each detection box 10 is the same, that is, it will not affect the detection of the air composition.

[0080] Control valves are provided on the elastic air inlet pipe 4 and multiple air-dividing square tubes 22. The control valves are used to control the opening and closing states of the elastic air inlet pipe 4 and the air-dividing square tubes 22. When the reciprocating air intake plate 21 moves to the left to inhale air, the control valve on the elastic air inlet pipe 4 is opened, so that the elastic air inlet pipe 4 is in a connected state for inhalation, and at the same time, the control valve on the air-dividing square tube 22 is closed, so that the air in the air-dividing square tube 22 will not be sucked out. When the reciprocating air intake plate 21 moves to the right to compress air, the control valve on the elastic air inlet pipe 4 is closed to make it in a closed state, and the control valve in the air-dividing square tube 22 is opened to make it in a connected state, so that the air can be pressed into the air-dividing square tube 22 during compression, and will not be pressed out through the elastic air inlet pipe 4.

[0081] Each gas distribution square tube 22 is provided with a discharge mechanism, which includes a filter screen 32 fixedly installed in the gas distribution square tube 22 for filtering impurities in the gas, a ash lowering pipe is fixedly installed at the lower part of the gas distribution square tube 22, and a discharge pipe 23 for discharge impurities is provided between the gas guide box 9 and the detector body 1;

[0082] When the air enters the gas separation square tube 22, it will contact the filter screen 32 therein. At this time, the filter screen 32 can filter out the particulate impurities in the air. After the gas detection is completed, the lower ash pipe can be opened to allow the impurities in the gas separation square tube 22 to fall to the bottom of the air guide box 9 through the lower ash pipe, and then the impurity discharge pipe 23 can be opened to discharge the impurities at the bottom of the air guide box 9.

[0083] In a further embodiment, the gas guide assembly includes a linkage plate 34 fixedly mounted on the ball nut plate 24, a linkage push plate 35 is slidably mounted in each detection box 10, and the gas detection sensor 26 is fixedly mounted on the linkage push plate 35, a reset spring rod 27 is fixedly mounted between the linkage push plate 35 and the detection box 10, a linkage pull rope 30 is fixedly connected between the linkage plate 34 and the linkage push plate 35, and a wire pulley 36 matching the linkage pull rope 30 is provided at the lower part of the detection box 10;

[0084] When the ball nut plate 24 moves to the left (instruction manual attached Fig. 9 When the reciprocating air intake plate 21 is moved leftward (in the direction shown in the figure) to inhale, the ball nut plate 24 moves leftward to loosen the linkage pull rope 30, thereby reducing the tension of the reset spring rod 27. At this time, the reset spring rod 27 will automatically extend and push the linkage push plate 35 to move rightward, thereby driving the gas detection sensor 26 thereon to move rightward as a whole, and simultaneously reducing the distance between the right side of the linkage push plate 35 and the detection box 10, that is, through the movement of the linkage push plate 35, the storage space of the air in the detection box 10 is reduced when no air is inhaled.

[0085] When the ball nut plate 24 moves to the right and drives the reciprocating air suction plate 21 to move to the right to compress the air, the rightward movement of the ball nut plate 24 will pull the linkage pull rope 30 and the traction action of the linkage pull rope 30 will pull the linkage push plate 35 to move it to the left in the detection box 10, so that the storage space can be increased while the air is taken in inside the detection box 10, thereby increasing the storage space of the air in the detection box 10 and improving the air storage range.

[0086] When the detection box 10 does not take in air, the gas detection sensor 26 will start to detect the composition of the air in the detection box 10, and the movement of the linkage push plate 35 when the detection box 10 does not take in air will reduce the storage space of the air, thereby compressing the air in the storage space, that is, pressurizing the air in the storage space. When the air is compressed, the speed of its molecular movement is accelerated, that is, the fluidity is accelerated, and the speed of its entering the gas detection sensor 26 can be accelerated;

[0087] That is, the speed at which the gas detection sensor 26 absorbs air is increased by compressing the air, thereby accelerating the detection efficiency of the gas detection sensor 26 .

[0088] In a further embodiment, a plurality of detection boxes 10 are commonly equipped with an exhaust mechanism for exhausting gas, the exhaust mechanism comprising an air suction bellows 11 fixedly installed in the detector body 1, and the air suction bellows 11 is rotatably connected to the driving roller 13, a one-way bearing rod 2 37 is provided on the driving roller 13, and the one-way bearing rod 2 37 rotates synchronously in the opposite direction under the driving of the reverse rotation of the driving roller 13, a suction impeller 38 is fixedly installed on the one-way bearing rod 2 37, and the suction impeller 38 is located in the air suction bellows 11;

[0089] When the air in the detection box 10 is detected, the servo motor 8 can be started to drive the driving roller 13 to reverse. When the driving roller 13 reverses, it will drive the one-way bearing rod 2 37 to rotate (the one-way bearing rod 1 31 does not rotate at this time). The rotation of the one-way bearing rod 2 37 will drive the suction impeller 38 thereon to rotate.

[0090] The suction bellows 11 is fixedly connected to a suction main pipe 28 through a return suction pipe 29, and a suction branch pipe 12 for sucking out the gas in the detection box 10 is fixedly connected between each detection box 10 and the suction main pipe 28, and an exhaust pipe 25 for exhausting gas is fixedly connected between the suction bellows 11 and the detector body 1;

[0091] When the suction impeller 38 rotates, suction force is generated in the suction bellows 11, so that the air in the detection box 10 is sucked into the suction bellows 11 through the return suction pipe 29, the suction main pipe 28 and the suction branch pipe 12, and discharged through the exhaust pipe 25;

[0092] The air in the detection box 10 can be completely sucked out by the cooperation of the suction impeller 38, so as to avoid the residual air in the detection box 10 affecting the subsequent gas detection results, and further improve the accuracy of the gas detection results.

[0093] The working principle of this detector is as follows:

[0094] Before testing, the length of the elastic air inlet pipe 4 is adjusted by adjusting the assembly, and its end is placed in the area to be tested, completing the test preparation work;

[0095] Then start the servo motor 8 to drive the driving roller 13 to rotate in the forward direction, thereby driving the reciprocating screw 14 to rotate, and then driving the ball nut plate 24 to reciprocate on the reciprocating screw 14, thereby driving the reciprocating air intake plate 21 to reciprocate left and right in the air guide box 9. When the reciprocating air intake plate 21 moves left in the air guide box 9, the space on the right side of the reciprocating air intake plate 21 in the air guide box 9 can be increased, and the external air to be detected can be sucked into the air guide box 9 through the elastic air intake pipe 4;

[0096] When the reciprocating air suction plate 21 moves to the right, the air sucked into the air guide box 9 can be pressed into a plurality of air distribution square tubes 22, and the corresponding air can be injected into the detection box 10 through the air distribution square tubes 22, so that the partitioned storage of the air can be completed, and the whole air can be divided into three parts and transmitted to the three detection boxes 10. At this time, the gas detection sensor 26 can be started to detect the composition of the gas in the detection box 10;

[0097] When the detection box 10 does not take in air, the linkage push plate 35 moves to reduce the storage space and pressurize the air in the storage space. When the air is compressed, the speed at which it enters the gas detection sensor 26 will be accelerated, thereby accelerating the detection efficiency of the gas detection sensor 26.

[0098] The embodiment of the present invention further provides a multi-mode fusion portable intelligent gas detection method, which is used for the above-mentioned multi-mode fusion portable intelligent gas detector, comprising the following steps:

[0099] S1. When performing gas detection, the length of the elastic air inlet pipe 4 is adjusted by adjusting the assembly, and the end of the elastic air inlet pipe 4 is extended into the area to be detected;

[0100] S2, start the air suction component to absorb the gas into the detector body 1 through the elastic air inlet pipe 4;

[0101] S3, the partition detection component stores the inhaled gas in partitions in cooperation with the gas guide component, and simultaneously starts the corresponding multiple gas detection sensors 26 to perform component detection in different modes on the gas in each partition;

[0102] S4. After the detection is completed, the gas in each partition is completely exhausted through the gas guide component, and the gas detection of the next area is carried out after the exhaust is completed.

[0103] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
