Description

Technical Field

[0001] The present invention belongs to the technical field of gas detection, and particularly relates to a gas flow rate amplification device based on a mobile device. Background Art

[0002] In the prior art, devices for detecting gas leakage mostly adopt an exhaust fan design, where the internal pressure is reduced by the rotation of a motor to suck in air for detection. However, this technology is only applicable to large-scale detection, with high costs, large instruments, and the need for many analytical instruments, and it cannot be applied to various detection environments. In addition, there is also a fixed detection instrument (similar to an electronic nose). This detection method has a certain time delay, is affected by natural factors such as wind, and requires many instruments to be installed, resulting in high costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a gas flow rate amplification device based on a mobile device in view of the above deficiencies of the prior art.

[0004] To achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0005] A gas flow rate amplification device based on a mobile device, comprising: a flow rate amplifier, the flow rate amplifier having an open structure with a large intake port and a small outlet port, wherein the outlet port is inserted into an exhaust pipe. A groove is provided on one side of the exhaust pipe close to the flow rate amplifier, and a gas sensor is installed in the groove. The detection end of the gas sensor is close to the outlet port of the flow rate amplifier. A sealing component is provided above the groove, which covers the exposed part of the groove and forms a sealed structure with the exhaust pipe and the gas sensor. A detection analyzer is installed on the exhaust pipe, and the detection analyzer is electrically connected to the gas sensor. A fixed installation component is provided on the side of the exhaust pipe away from the flow rate amplifier, which is used to fix the exhaust pipe on the mobile device, and the fixed installation component can axially move and circumferentially rotate relative to the exhaust pipe.

[0006] To optimize the above technical solution, the specific measures taken further include:

[0007] The outer surface of the above flow rate amplifier is of a streamline structure, and the inner surface is of a hemispherical structure, thereby reducing the disturbance to the air.

[0008] The above sealing component includes a limiting rod and a sealing baffle. The limiting rod is provided on the exhaust pipe between the groove and the flow rate amplifier. The sealing baffle is movably provided between the limiting rod and the exhaust pipe and can slide to the right to abut against the gas sensor, thereby sealing the exposed part of the groove.

[0009] The above sealing baffle is provided with a convex block for moving the sealing baffle.

[0010] The above-mentioned fixed installation component includes an annular clamp and a fixing plate. One end of the annular clamp is bolted and fastened, and the other end is bolted to the fixing plate. The annular clamp is clamped on the exhaust pipe.

[0011] A plurality of mounting holes are provided on the above-mentioned fixing plate, and the fixing plate is bolted to the mobile device through the mounting holes.

[0012] A connecting plate is fixedly installed on the above-mentioned exhaust pipe, and the fixed end of the gas sensor is fixedly installed on the connecting plate through bolts.

[0013] The model of the above-mentioned gas sensor is the ZYMQ series.

[0014] The gases detected by the above-mentioned gas sensor are ethanol, methane, carbon monoxide and hydrogen.

[0015] The model of the above-mentioned detection analyzer is the STM32 single-chip microcomputer.

[0016] Advantages of the present invention:

[0017] Compared with the prior art, in which the direct contact reaction between the gas sensor and the gas has a small reaction amount and a slow reaction speed, through the streamline surface of the flow rate amplifier, the disruption of the gas components is reduced; through the combination of the flow rate amplifier and the exhaust pipe, the gas flow rate is increased, making the reaction speed of the gas sensor faster; through the design of the sealing structure, it is ensured that all the detected gases will pass through the detection part of the gas sensor for detection, greatly improving the detection efficiency and detection accuracy.

[0018] At the same time, it is also convenient to install on a variety of mobile devices, making it more convenient; in addition, for large-scale working area detection, by installing it on a tracing device, the work efficiency can be greatly improved, the workload of workers can be reduced, and the use of some fixed detection devices can also be reduced, thus reducing costs.

Detailed implementation manners

[0023] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] As Figure 1 shown, the present invention is a gas flow rate amplification device based on a mobile device, wherein: it includes a flow rate amplifier 1, and the flow rate amplifier 1 has an open structure with a large intake port and a small outlet port. The outlet port is inserted into an exhaust pipe 2. A groove is provided on one side of the exhaust pipe 2 close to the flow rate amplifier 1. A gas sensor 3 is installed in the groove. The detection end of the gas sensor 3 is close to the right end face of the flow rate amplifier 1. A sealing component 4 is provided above the groove. The sealing component 4 covers the exposed part of the groove and forms a sealed structure with the exhaust pipe 2 and the gas sensor 3. A detection analyzer 5 is installed on the exhaust pipe. The detection analyzer 5 is electrically connected to the gas sensor 3. A fixed installation component 6 is provided on the side of the exhaust pipe 2 away from the flow rate amplifier 1. The fixed installation component 6 is used to fix the exhaust pipe 2 on the mobile device, and the fixed installation component 6 can axially move and circumferentially rotate relative to the exhaust pipe 2.

[0025] Figure 2 It is a schematic semi-sectional view. As can be seen from the figure, the outer surface of the flow rate amplifier 1 is a streamlined structure, and the inner surface is a hemispherical structure. The left end face of the flow rate amplifier 1 is the intake port, and the right end face is the outlet port. This structure can reduce the disturbance to the gas. A limit rod 4-1 is provided on the exhaust pipe 2 between the groove and the flow rate amplifier 1. A sealing baffle 4-2 is movably arranged between the limit rod 4-1 and the exhaust pipe 2. The sealing baffle 4-2 can slide to the right and abut against the gas sensor 3. A convex block 4-3 is provided on the sealing baffle 4-2 for moving the sealing baffle 4-2. A connecting plate 7 is fixedly installed on the exhaust pipe 2. The gas sensor 3 is fixedly installed on the connecting plate 7 by bolts. First, air enters from the intake port of the flow rate amplifier 1 and then exits from the outlet port of the flow rate amplifier 1. At this time, the air flow rate increases and blows towards the detection part of the gas sensor 3. When passing through the gas leakage part, the gas sensor 3 sends the detected information to the detection analyzer 5, and the detection analyzer 5 analyzes the components of the air in real time to determine the specific position of the gas leakage. The excess gas is discharged from the exhaust pipe 2.

[0026] The gases to be detected are ethanol, methane, carbon monoxide and hydrogen. The model of the gas sensor 3 is the ZYMQ series, and the model of the detection analyzer 5 is the STM32 single-chip microcomputer.

[0027] As Figure 3The following is a schematic structural diagram of a fixed installation component. The fixed installation component 6 includes an annular clamp 6-1 and a fixing plate 6-2. One end of the annular clamp 6-1 is bolted and fastened, and the other end is connected to the fixing plate 6-2. The annular clamp 6-1 is clamped on the exhaust pipe 2. A number of mounting holes 6-3 are provided on the fixing plate 6-2. The fixing plate 6-2 is bolted to the mobile device through the mounting holes 6-3. By loosening or tightening the bolts of the annular clamp, the fixed installation component 6 can be axially moved and circumferentially rotated on the exhaust pipe. At the same time, by loosening or tightening the bolts between the annular clamp 6-1 and the fixing plate 6-2, the fixing plate 6-2 can be rotated relative to the annular clamp 6-1, so as to meet the requirements of multi-angle and multi-position installation and fixation on the mobile device.

All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and modifications made without departing from the principle of the present invention should be regarded as within the protection scope of the present invention.
