Technical Field

[0001] This utility model relates to the field of rescue equipment technology, and more specifically, to a silencer gas cylinder. Background Technology

[0002] In the event of underground rescue or collapse, the confined space underground may contain toxic gases, necessitating air replacement and providing breathing for trapped personnel. However, the exhaust noise of existing air respirators is loud, which can easily cause tension and panic among trapped personnel and disrupt communication for underground rescuers. Therefore, it is necessary to solve this problem. Utility Model Content

Therefore, one objective of this invention is to provide a silencer gas cylinder that uses a silencer to reduce noise and minimize interference and harm to people, thus facilitating smoother underground rescue operations.

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] like Figures 1 to 3 As shown, a silencer cylinder includes:

[0032] Bottle 1, which contains the gas needed for the rescue;

[0033] Silencer 2, which is detachably connected to the bottle mouth of the bottle body 1.

[0034] In this specific application, the silencer 2 is detachably connected to the bottle 1. When a rescue operation is needed in the well, the gas stored in the bottle 1 is released. The gas in the bottle 1 forms an airflow that is discharged through the silencer 2. The silencer 2 can reduce the noise of the airflow, significantly reducing the audible sound components in the spectrum, thereby reducing interference and harm to people and making the rescue operation in the well smoother.

[0035] In the above embodiment, the muffler 2 has a cylindrical structure, and a plurality of muffler holes 201 are provided on the side wall of the muffler 2, the diameter of the plurality of muffler holes 201 being less than or equal to 1 mm.

[0036] In practical applications, the aperture of the silencing hole 201 is less than or equal to 1 mm. When the sound waves of the airflow propagate to the surface of the material with the silencing hole 201, the silencing hole 201 can generate strong viscous loss for high-frequency noise. This can increase the friction between air molecules and the hole wall when the high-frequency sound waves pass through the silencing hole 201, converting sound energy into heat energy, thereby effectively reducing high-frequency noise and making the sound emitted when the airflow flows softer. From the perspective of resonance frequency, the silencing hole 201 will increase the resonance frequency of the silencer 2, making it easier for high-frequency sound to resonate and absorb, preventing high-frequency noise from propagating outward and improving quietness.

[0037] The silencing hole 201 can scatter sound, redistribute the incident sound wave in all directions, thereby reducing sound reflection. It can not only silence the sound, but also reduce the reverberation time in the well, making the sound clearer.

[0038] When the airflow passes through the silencer hole 201, the small size of the silencer hole 201 generates greater resistance, which can reduce the flow velocity of the fluid and thus reduce the noise generated by the gas flow. The silencer hole 201 can also precisely control the airflow rate, ensuring a stable micro-flow rate while reducing noise during the gas flow process. In addition, the silencer hole 201 can prevent particles and impurities from clogging the flow, making it more suitable for downhole rescue and keeping the airflow clean, thereby maintaining the long-term stability of the silencer 2.

[0039] In the above embodiments, such as Figure 2 and Figure 3 As shown, the sidewall of the muffler 2 is made of stainless steel plate, and the thickness of the sidewall of the muffler 2 is less than 1.0 mm.

[0040] In practical applications, the silencer 2 made of stainless steel plate can improve the stability of the silencer 2, resist corrosion, withstand high temperature, have high strength and hardness, can withstand certain pressure and impact, have a beautiful appearance and are easy to clean; it can effectively adapt to the harsh environment downhole and extend its service life; when the silencer 2 is used in conjunction with sound-absorbing materials, it can improve the noise reduction effect.

[0041] In the above embodiment, the muffler 2 is filled with soft metal filament cloth.

[0042] In practical applications, metal filament cloth typically has a complex mesh structure. When sound waves from the airflow enter, the sound propagates through the gaps and pores between the metal wires, causing air vibrations. These tiny vibrations convert some of the sound energy into heat energy, thus absorbing the sound. The sound waves interact with the rough surfaces of the metal wires, producing scattering and reflection. These reflected and scattered waves interfere with each other within the metal filament cloth, resulting in destructive interference, which weakens the sound energy and achieves a sound absorption effect. The metal filament cloth affects its response to sound frequencies; finer metal wires and higher wire density may have a better absorption effect on high-frequency sounds.

[0043] In the above embodiments, such as Figure 2 and Figure 3 As shown, one end of the muffler 2 is closed, and the other end is provided with an air inlet. An air inlet plate 202 is fixedly provided at the air inlet, and multiple air inlets 203 are provided on the air inlet plate 202.

[0044] In practical applications, multiple air inlets 203 precisely control the airflow, ensuring a stable flow of small amounts of gas while reducing noise during gas flow. Combined with the silencer holes 201 on the silencer 2, the noise reduction effect can be further enhanced.

[0045] In the above embodiments, such as Figure 2 and Figure 3 As shown, the bottle body 1 is provided with multiple bottle openings, one of which is detachably connected to the silencer 2, and the other bottle openings are detachably closed by the switch assembly 3.

[0046] In practical applications, the multiple openings of bottle 1 facilitate rapid inflation or deflation of bottle 1, improving the efficiency of downhole rescue.

[0047] In the above embodiments, such as Figure 1 As shown, the bottle body 1 is provided with a strap 4 wrapped around the bottle body 1.

[0048] In practical applications, the strap 4 facilitates the carrying of the bottle 1 and the silencer 2, enabling rapid rescue operations. During underground rescues, the strap 4 can be disassembled and used to rescue personnel in need. The strap 4 can also protect the bottle 1.

[0049] In the above embodiments, such as Figure 1 As shown, the bottom of the bottle body 1 is provided with a hook 5 that is movably connected to it. The hook 5 makes it easy to hang the bottle body 1 on the body or on the wall in the well, which is convenient for carrying and for underground rescue.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
