[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0026] Please refer to Figures 1-5 , the present utility model provides a technical solution: including an installation box 1. The installation box 1 is a small and portable rectangular structure. The bottom of the inner wall of the installation box 1 is fixedly connected by welding with a gas detector 6. The gas detector 6 is fixedly connected by a pipeline with an air extraction pump 7. One end of the air extraction pump 7 away from the gas detector 6 is fixedly connected by a pipeline with an air delivery pipe 8. The air delivery pipe 8 is in a C-shaped structure, and the two vertical pipes of the air delivery pipe 8 are perpendicular to the horizontal pipe. One end of the horizontal pipe of the air delivery pipe 8 is fixedly connected by welding with a first ball valve 9. The other end of the horizontal pipe of the air delivery pipe 8 is fixedly connected by welding with a second ball valve 10. One vertical pipe of the air delivery pipe 8 near the first ball valve 9 is fixedly connected by welding with an air inlet ring 11. The air inlet ring 11 is fixedly connected to the outer wall of the installation box 1 by welding. Gas then enters the air delivery pipe 8 from the air inlet ring 11 and finally enters the interior of the gas detector 6 through the air extraction pump 7. One vertical pipe of the air delivery pipe 8 near the second ball valve 10 is fixedly connected by threading with a hose 4. One end of the hose 4 away from the air delivery pipe 8 is fixedly connected by adhesion with a nozzle 16. A pipe orifice 12 is opened on the surface of the installation box 1. The hose 4 passes through the pipe orifice 12 to realize air circulation with the outside. Gas enters the hose 4 through the nozzle 16 and finally enters the interior of the gas detector 6 through the air delivery pipe 8;

[0027] Inside the installation box 1, there is a storage component 5. The storage component 5 is used to store the hose 4 to prevent the excessive length of the hose 4 from affecting its use. The storage component 5 includes a storage box 501. The storage box 501 is a cylindrical hollow structure. At the bottom of the inner wall of the storage box 501, a driving motor 505 is fixedly connected by means of bolts. The output end of the driving motor 505 is fixedly connected by welding with a rotating plate 504. The rotating plate 504 is a circular structure, and the radius length of the rotating plate 504 is less than the radius length of the inner wall of the installation box 1. The inner wall of the installation box 1 is fixedly connected by welding with a first baffle 502 and a second baffle 503. The first baffle 502 and the second baffle 503 are circular ring structures with the same shape, and the first baffle 502 is located above the rotating plate 504, and the second baffle 503 is located below the rotating plate 504. When the rotating plate 504 rotates with the driving motor 505, the first baffle 502 and the second baffle 503 can prevent the rotating plate 504 from shaking. The top of the rotating plate 504 is fixedly connected by welding with a limiting plate 506. The limiting plate 506 is composed of two concentric arc plates with different radii. The arc plate with a smaller arc is located on the inner circle, and the arc plate with a larger arc is located on the outer circle. An arc track is formed between the two arc plates to prevent the hose 4 from being wound when the hose 4 is stored. The surface of the storage box 501 is provided with an inlet pipe hole 507 and an outlet pipe hole 508. The inlet pipe hole 507 is located below the rotating plate 504, and the outlet pipe hole 508 is located above the rotating plate 504, and the outlet pipe hole 508 is on the same horizontal plane as the limiting plate 506. The included angle formed between the inlet pipe hole 507 and the outlet pipe hole 508 is 90 degrees. When the hose 4 enters the interior of the storage box 501 from the inlet pipe hole 507, it passes through the rotating plate 504, passes through the arc track between the limiting plates 506, and then passes through the outlet pipe hole 508. When the hose 4 is stored, the driving motor 505 drives the rotating plate 504 to rotate between the first baffle 502 and the second baffle 503, and uses circular motion to wind the hose 4 around the limiting plate 506, thereby realizing the storage of the hose 4;

[0028] At the bottom of the inner wall of the installation box 1, a display screen 3 is fixedly connected by means of adhesion. At the top of the display screen 3, control buttons 17 are fixedly connected by means of embedding. At the bottom of the inner wall of the installation box 1, a buzzer 13 is fixedly connected by means of adhesion. The buzzer 13 and the display screen 3 are electrically connected by means of wires. When the display screen 3 reads the value of the gas, the signal is transmitted to the buzzer 13, and the buzzer 13 gives an alarm according to the setting. At the bottom of the inner wall of the installation box 1, a storage battery 14 is fixedly connected by means of bolts. The storage battery 14 is electrically connected to the display screen 3, the gas detector 6, the air extraction pump 7, the buzzer 13 and the driving motor 505 by means of wires, and provides a power source for them;

[0029] One side of the installation box 1 is fixedly connected to the cover plate 2 by means of a hinge. The length of the cover plate 2 is the same as that of the installation box 1. The installation box 1 and the cover plate 2 are fixedly connected by welding with a buckle 15. An observation hole 18 is formed on the surface of the cover plate 2. The length of the observation hole 18 is greater than the length of the display screen 3. When the cover plate 2 is buckled to the installation box 1 through the buckle 15, the gas value can be observed and the control button 17 can be operated without opening the cover plate 2.

[0030] Working principle: When in use, this utility model collects gas through the gas nozzle 16 and the intake ring 11, then transports the gas to the inside of the gas detector 6 through the gas pipeline 8, so as to detect the gas. Finally, the display screen 3 and the buzzer 13 are used to achieve the purpose of gas detection. First, according to different gas detection modes, different collection methods are selected. When it is necessary to detect the gas concentration in the overall environment, the intake ring 11 is used to collect gas. First, close the second ball valve 10 to close the intake channel at the gas nozzle 16 end, and then form a closed space by connecting the cover plate 2 to the installation box 1 through the buckle 15. At this time, start the air pump 7 through the control button 17 on the display screen 3. Under the action of the air pump 7, the intake ring 11 starts to suck the gas in the environment. The gas enters the gas pipeline 8 through the intake ring 11, and then passes through the first ball valve 9 and the air pump 7, and finally enters the inside of the gas detector 6. Because the second ball valve 10 is in the closed state, the gas will not pass through the second ball valve 10. When the gas detection in the gas detector 6 is completed, the value is transmitted to the display screen 3 in the form of an electrical signal. The display screen 3 then transmits the value to the buzzer 13 in the form of an electrical signal. The buzzer 13 processes the gas value alarm according to the set program. When it is necessary to detect the gas in a narrow place and it is inconvenient for the alarm instrument to go deep, the gas nozzle 16 is selected to collect gas. First, pull out the hose 4 from the storage box 501. Because the hose 4 is rotatably fixed on the rotating plate 504, the hose 4 can be normally pulled out. The lengthened hose 4 is stretched to the outside through the nozzle 12, then open the second ball valve 10, close the first ball valve 9, cover the cover plate 2, and insert the gas nozzle 16 into the narrow place where the gas needs to be detected. After the gas nozzle 16 is installed, press the control button 17 to start the air pump 7. Under the action of the air pump 7, the gas nozzle 16 starts to collect gas. The gas enters the gas pipeline 8 through the hose 4, and then passes through the second ball valve 10 and the air pump 7, and finally enters the inside of the gas detector 6. Then the gas detector 6 transmits the value of the detected gas to the display screen 3 in the form of an electrical signal. The display screen 3 then transmits the value of the detected gas to the buzzer 13 in the form of an electrical signal. The buzzer 13 alarms the gas value according to the set program. When the gas detection is completed, open the cover plate 2, retract the hose 4 into the installation box 1, press the control button 17 to start the drive motor 505. Under the action of the drive motor 505, the rotating plate 504 starts to rotate under the restriction of the first baffle 502 and the second baffle 503. Due to the track restriction of the limit plate 506, the hose 4 starts to rotate and wind according to the track of the limit plate 506. When the hose 4 is completely retracted, press the control button 17 to pause the operation of the drive motor 505, and the hose 4 is completely retracted. Test by closing both the first ball valve 9 and the second ball valve 10, covering the cover plate 2, and the use of the gas alarm is completed.
