Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinder leakage detection, in particular to a gas cylinder leakage detection alarm device. Background Art

[0002] A gas cylinder is a pressure vessel used to store and transport gas. It is usually made of metal or a combination of metal and non-metallic materials. They have specific structural and design requirements. Gas cylinders can be classified according to different classification standards, such as purpose, gas type, pressure level, material, etc. When a gas cylinder leaks, a leak detection alarm device is required to detect the leak in time.

[0003] Through research and analysis, it is found that although the existing leakage detection alarm device can detect leakage, it still has the following shortcomings to a certain extent.

[0004] For example, when in use, it can only detect leakage of the gas cylinder, and it does not have the function of preventing the leaked gas from scattering, so the gas will diffuse in the air. Some gas cylinders contain toxic gases, which are easy to cause workers to inhale and cause harm to the workers. Moreover, the leaked gas directly diffuses in the air, and it does not have the function of conveniently collecting the leaked gas, thus causing gas waste and increasing the losses caused by the leakage. In order to solve the above technical problems, we have designed a gas cylinder leakage detection alarm device. Utility Model Content

[0005] The purpose of the utility model is to provide a gas cylinder leakage detection alarm device, which has the advantages of preventing the leaked gas from scattering and facilitating the collection of the gas leaked from the gas cylinder, thereby solving the problems of not being able to prevent the leaked gas from scattering and being inconvenient to collect the gas leaked from the gas cylinder.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gas cylinder leakage detection and alarm device, comprising a sealing shell, an exhaust assembly is installed on the top of the sealing shell, the exhaust assembly comprises a connecting shell and an exhaust fan, the bottom end of the connecting shell passes through the top of the sealing shell, the top of the connecting shell is fixedly connected to an exhaust valve, a sealing fixing assembly is installed on the bottom of the sealing shell, the sealing fixing assembly comprises a sealing ring and a clamping plate, the top of the sealing ring is fixedly connected to the bottom of the sealing shell by bolts, and the inner wall of the sealing shell and the inner wall of the sealing ring are respectively bonded with a second sealing ring and a first sealing ring.

[0007] Preferably, a short plate is welded to the inner wall of the connecting shell, the surface of the exhaust fan is fixedly connected to one end of the short plate by bolts, the top of the exhaust valve is fixedly connected to a telescopic hose, and the top end of the telescopic hose is fixedly connected to a connecting head.

[0008] Preferably, a vertical plate is connected to the left side of the top of the connecting shell via bolts, and an elastic clamping ring is welded to the top of the right side of the vertical plate.

[0009] Preferably, the left and right sides of the sealing ring are connected with U-shaped plates by bolts, a connecting plate is welded to the bottom of the U-shaped plate, a connecting threaded rod is penetrated through the surface of the connecting plate, and one side of the clamping plate is movably connected to one end of the connecting threaded rod through a bearing.

[0010] Preferably, a knob is welded on one end of the connecting threaded rod away from the clamping plate, and a connecting nut is threadedly sleeved on the surface of the connecting threaded rod.

[0011] Preferably, one side of the connecting nut is welded to the surface of the connecting plate, and one side of the clamping plate is welded with a guide rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model has the advantage of preventing leaked gas from scattering by matching a sealing cover shell, a sealing ring, a clamping plate, a first sealing ring, a second sealing ring, a guide rod, a knob, a connecting nut and a connecting threaded rod. The sealing ring is put on the gas cylinder so that the sealing shell can seal the top of the gas cylinder. By turning the knob, the connecting threaded rod is rotated. Under the guidance of the guide rod, the clamping plate is moved to clamp the gas cylinder, so that the sealing ring and the sealing shell can be fixed on the gas cylinder. Under the action of the first sealing ring and the second sealing ring, the sealing performance of the sealing ring and the sealing shell is improved, thereby preventing gas from scattering.

[0016] 2. The utility model has the advantage of facilitating the collection of gas leaked from the gas cylinder by cooperating with the connecting shell, the telescopic hose, the connecting head, the exhaust valve, the exhaust fan and the short plate. When the leaked gas needs to be collected, the telescopic hose is connected to the collection bottle, the exhaust valve is opened, and the exhaust fan is running to absorb the gas leaked in the sealed shell, so that the gas can be discharged into the collection bottle through the exhaust valve and the telescopic hose for collection, thereby preventing waste and reducing losses caused by leakage.
