[0020] Please see Figure 1-6 This utility model provides the following technical solution: a gas alarm detection device, including a main body 1, a hose 2, a mounting block 3, and a detector 6, and also includes a mixing pipe 4 and an extension pipe 5. The main body 1 has two gas storage tanks 11 inside, with hoses 2 attached to each tank. The mounting block 3 has a gas delivery pipe 32 inside, with a valve on each section of the gas delivery pipe 32. The hoses 2 are connected to the mounting block 3. A threaded ring 31 is rotatably mounted on the mounting block 3, and the threaded ring 31 is threaded onto the main body 1. The mixing pipe 4 is mounted on the gas delivery pipe 32, and the mixing pipe 4 is threaded onto... The main body 1 is equipped with a detection tube 41, which contains a detector 6. A cap is threaded onto the detection tube 41. A storage trough 12 is provided on the side wall of the main body 1. An array of mounting rings 13 is provided inside the storage trough 12. An extension tube 5 is installed on the mounting rings 13. Both ends of the extension tube 5 are respectively provided with matching threaded cylinders and threaded grooves. The threaded cylinders on the extension tube 5 match the threaded grooves of the detection tube 41. Rubber pads are provided on the end faces of the mixing tube 4, the detection tube 41, and the extension tube 5. Matching annular protrusions and grooves are provided on the end faces of the detection tube 41 and the extension tube 5.

[0021] The main body 1 houses a power supply and controller. Two gas storage tanks 11 are used to store nitrogen and natural gas respectively. A hose 2 is connected to a gas pump installed on the gas storage tank 11. The hose 2 is used to transport the gas stored in the gas storage tank 11. The hose 2 is made of flexible material, and the user can bend the hose 2 according to the actual situation when using the device. The top surface of the main body 1 has a groove for accommodating the hose 2, ensuring that the hose 2 will not obstruct the installation of the mounting block 3. The main body 1 has a threaded groove that mates with the threaded ring 31. When installing the mounting block 3, the threaded ring 31 is rotated, and the threaded ring 31 is installed on the main body 1 through the threads. At this time, the mounting block 3 is fixed on the main body 1, and the threaded ring 31 is rotated and installed on the mounting block 3, ensuring that the mounting block 3 is securely installed by the user during the installation process. To ensure stability during the process, the bottom surface of the threaded ring 31 is provided with a groove, which provides a force application position for the user to rotate the threaded ring 31, facilitating rotation. The gas supply pipe 32 is used to supply gas. The gas supply pipe 32 has three openings. The gas supplied by the hose 2 is sent into the interior of the mixing pipe 4 through the gas supply pipe 32. The gases inside the mixing pipe 4 are mixed together, realizing the adjustment of the natural gas concentration. Each pipe of the gas supply pipe 32 is equipped with a valve. The user can control the closure and connection of each pipe of the gas supply pipe 32 through the valves, realizing the individual adjustment of the delivery speed of nitrogen and natural gas, facilitating the user to adjust the concentration of the mixed natural gas. The mixing pipe 4 is used for mixing gases and detection. Pipe 41 is used to install detector 6, which is used to detect the concentration of natural gas inside mixing pipe 4, allowing users to adjust the concentration. The detachable detection pipe 41 facilitates maintenance of detector 6. The sealing plug on detection pipe 41 seals the mixing pipe 4, preventing external debris from entering the mixing pipe 4 when the device is not in use. Extension pipe 5 extends the length of the outlet of detection pipe 41, making the device suitable for alarms of different heights. The end face of the outlet of detection pipe 41 and both ends of extension pipe 5 are provided with matching threaded sleeves and threaded grooves. The installation method of extension pipe 5 facilitates user adjustment of the outlet length. Sealing gaskets are provided on the end faces of mixing pipe 4, detection pipe 41, and extension pipe 5. The mounting block 3 serves to seal the gaps at the installation points of the mixing pipe 4, the detection pipe 41, and the extension pipe 5, preventing natural gas leakage during transportation. The annular grooves and protrusions on the end faces of the mixing pipe 4, the detection pipe 41, and the extension pipe 5 further enhance the sealing performance at their installation points. The storage trough 12 stores the extension pipe 5, and the mounting ring 13 secures the extension pipe 5 inside the storage trough 12, ensuring the stability of the extension pipe 5 during device use. The mounting block 3 is installed on the main body 1 via a threaded ring 31, and the extension pipe 5 is fixed to the storage trough 12 via the mounting ring 13. The mounting block 3 installed on the main body 1 and the extension pipe 5 fixed by the mounting ring 13 facilitate user carrying of the various components of the device.To facilitate user portability, a set of mounting rings 13 consists of two mating mounting rings 13. During use, the two mounting rings 13 securely fasten an extension tube 5, ensuring effective fixation of the extension tube 5.

[0022] Specifically, the extension tube 5 has a protrusion on the side wall of one end of the threaded cylinder, a movable ring 52 is slidably installed on the protrusion on the side wall of the extension tube 5, a liquid storage chamber 51 is provided on the protrusion on the side wall of the extension tube 5, a liquid storage frame 53 is provided on the side wall of the liquid storage chamber 51 and a limiting ring 54 that cooperates with the liquid storage frame 53 is provided on the side wall of the liquid storage chamber 51.

[0023] The storage tank 51 is used to hold soapy water. The moving ring 52 is slidably mounted on the side wall protrusion of the extension pipe 5. The side wall protrusion of the extension pipe 5 and the opposite side wall of the moving ring 52 are provided with matching annular grooves and protrusions. The cooperation between the side wall protrusion of the moving ring 52 and the matching groove ensures the stability of the moving ring 52 after it is mounted on the side wall protrusion of the extension pipe 5. The moving ring 52 acts as a seal for the storage tank 51 to prevent soapy water from leaking to the outside. The storage frame 53 is used to hold the soapy water stored inside the storage tank 51. When the user moves the moving ring 52, the storage frame 53 moves towards the end face of the extension pipe 5 with the soapy water stored inside. At this time, the soapy water will adhere to the detection pipe 41 and the extension pipe 5, as well as the connection between the two extension pipes 5, so that the user can quickly determine the natural gas being transported. To prevent leakage during the process, the limiting ring 54 acts as a stop, ensuring that the liquid storage frame 53 remains inside the liquid storage chamber 51 during movement. This ensures that the sealing of the liquid storage chamber 51 is not affected by the movement of the moving ring 52. A certain distance is maintained between the limiting ring 54 and the liquid storage frame 53 to facilitate the flow of soapy water. The opposite sidewalls of the liquid storage frame 53 and the limiting ring 54 are provided with matching protrusions and grooves. When the protrusion of the sidewall of the limiting ring 54 enters the matching groove, the liquid storage frame 53 is mounted on the limiting ring 54, ensuring the stability of the moving ring 52. The end face of the protrusion on the sidewall of the extension tube 5 is provided with a groove, which provides a force application position for the user to move the moving ring 52, making it convenient for the user to move the moving ring 52.

[0024] Specifically, the mounting ring 13 located above has an opening on its side wall, and the side wall of the opening of the mounting ring 13 is inclined outward.

[0025] The mounting ring 13 is elastic. When the extension tube 5 is inserted into the side wall opening of the mounting ring 13, the mounting ring 13 is pushed. At this time, the extension tube 5 can be installed on the upper mounting ring 13. Then, the extension tube 5 is moved down to move into the lower mounting ring 13, so that the extension tube 5 can be installed on both mounting rings 13. This realizes the quick installation of the extension tube 5 and improves the efficiency of the user in installing the extension tube 5. The side wall shape of the side wall opening of the mounting ring 13 makes it easy for the user to insert the extension tube 5 into the side wall opening of the mounting ring 13. The top of the inner wall of the lower mounting ring 13 is sloping. The sloping side wall of the mounting ring 13 plays a guiding role, making it easy for the user to move the extension tube 5 into the interior of the lower mounting ring 13.

[0026] Specifically, the distance between the two mounting rings 13 that match the array is different.

[0027] The distance between the two mounting rings 13 in each group is different, so that the mounting rings 13 can fix extension tubes 5 of different lengths while ensuring the fixing effect of the mounting rings 13 on extension tubes 5 of different lengths. Users can install extension tubes 5 of different lengths together according to the actual situation, so that the device can be used for alarms of different heights, thus improving the applicability of the device.

[0028] Specifically, the inside of the groove for mounting the hose 2 in the main body 1 is provided with two guide rollers 21 located at the top and bottom respectively. The hose 2 passes around the guide rollers 21, and the lower guide roller 21 is slidably mounted on the groove on the top surface of the main body 1. The side wall of the groove for mounting the guide roller 21 is provided with a self-rewinding spool 22 connected to the guide roller 21 by a pull wire.

[0029] By bypassing the guide roller 21, the hose 2 is neatly stored, preventing it from tangling during storage and affecting its gas delivery capacity. A sliding guide roller 21 is used; when the user pulls the hose 2, the guide roller 21 is pushed by the moving hose 2, allowing the hose 2 to unfold quickly and easily. During this pushing action, the pull cord on the self-rewinding spool 22 is pulled out. When the user retracts the hose 2, releasing the pull causes the self-rewinding spool 22 to rewind the cord, and the guide roller 21 moves rapidly downwards under its pull. This downward movement pushes the hose 2, achieving automatic storage and improving the efficiency of hose storage. As the hose 2 moves, the guide roller 21 rotates with it, reducing damage to the hose 2 during movement.

[0030] Specifically, the guide roller 21 located above has a limiting rod on its side wall that cooperates with the hose 2.

[0031] The upper guide roller 21 is fixed. The cooperation between the guide roller 21 and the limiting rod plays a limiting role, ensuring that the hose 2 will not detach from the upper guide roller 21 during the pulling process, thus ensuring the stability of the hose 2. When the moving guide roller 21 is used to retract the hose 2 under the action of the self-rewinding spool 22, the cooperation between the fixed guide roller 21 and the limiting rod ensures the stability of the hose 2 and ensures the effective retraction of the hose 2 by the guide roller 21.

[0032] Specifically, rollers are installed on the side wall of the groove through which the guide roller 21 is mounted and through which the pull line of the self-rewinding spool 22 passes.

[0033] The rollers on the side wall of the groove through which the pull wire wound on the self-rewinding spool 22 passes serve as guides, ensuring that the pull wire does not come into contact with the corner of the groove through which the pull wire passes during movement, reducing damage to the pull wire during movement and extending the service life of the pull wire.

[0034] The working principle and usage process of this utility model are as follows: Install extension tubes 5 of appropriate length according to the length of the alarm. Install the extended tubes 5 together on the detection tube 41. Move the moving ring 52, which moves the liquid storage frame 53. As the moving ring 52 and the liquid storage frame 53 move, the soapy water in the liquid storage frame 53 is applied to the installation points of the detection tube 41 and the extension tubes 5. Move the moving ring 52 back to its original position. Open the valve on the gas delivery pipe 32. The gas storage tank 11 delivers nitrogen and natural gas into the mixing pipe 4 through the hose 2 and the gas delivery pipe 32. The detector 6 detects the concentration of the mixed natural gas. Adjust the valve on the channel connecting the gas delivery pipe 32 and the hose 2 until the concentration of the mixed natural gas is reached. When the gas concentration reaches the required level, rotate the threaded ring 31. Under the action of the thread, the threaded ring 31 disengages from the main body 1, and the mounting block 3 is removed from the main body 1. Move the mounting block 3, which moves the hose 2. As the hose 2 moves, the guide roller 21 is also moved, thus unfolding the hose 2. This allows the opening of the extension tube 5, which is installed together, to approach the alarm, enabling the alarm to be detected. After the detection is completed, close the valve, remove the extension tube 5, and install the removed extension tube 5 on the mounting ring 13. Then, install the mounting block 3 on the main body 1 through the threaded ring 31. As the mounting block 3 is installed, the guide roller 21, which is pushed by the hose 2, moves back to its original position under the pull of the self-rewinding shaft 22, thus automatically retracting the hose 2.
