The embodiment provides a gas extraction device, as shown in fig. 1 and 2, which comprises a gas collecting hood 1, a wind shielding assembly, a second air extraction unit and a blowing unit; specifically, the gas collecting channel 1 is arranged above the exhaust port of the workbench 300; the wind shielding assembly is arranged between the gas collecting hood 1 and the workbench 300, and the wind shielding assembly, the workbench 300 and the gas collecting hood 1 form an accommodating space; the second air draft unit is arranged on the wind shielding assembly, and an air inlet of the second air draft unit is communicated with the accommodating space; the air inlet of the blowing unit is communicated with the air outlet of the second air draft unit, the air outlet of the blowing unit is communicated with the accommodating space, the air outlet of the blowing unit faces the gas collecting hood 1, and the blowing unit and the second air draft unit are arranged on two sides of the air outlet of the workbench 300.

The holding space formed by the wind shielding assembly, the workbench 300 and the gas collecting hood 1 is used for holding substances such as harmful gas generated on the workbench 300, and can prevent the harmful gas from diffusing to the periphery. In the operation process, part of harmful gas automatically drifts into the gas-collecting hood 1; part of harmful gas close to the wind shielding assembly enters a second air draft unit arranged on the side, and the second air draft unit is communicated with a blowing unit, so that the harmful gas enters the blowing unit after passing through the second air draft unit, and the blowing unit blows out the harmful gas and can jet to enable the harmful gas to move to a gas collecting hood 1; harmful gas towards unit one side of blowing probably is not taken away by the second convulsions unit, when the unit of blowing blows, accessible efflux will not be driven to the gas collecting channel 1 in by the gas that the second convulsions unit took away to make harmful gas get into gas collecting channel 1 respectively, finally take out through first convulsions unit, effectively solved harmful gas to the problem of diffusion all around on workstation 300, improved the validity of collecting gas, and then improved and taken out the effect. The blowing unit and the second air draft unit are respectively arranged on two sides of the workbench 300, and can respectively collect gas from two sides of the workbench 300 into the gas collecting hood 1, so that the gas collecting effect is improved.

Optionally, as shown in fig. 1 and fig. 2, the blowing unit includes a centrifugal fan 2, the centrifugal fan 2 is disposed below the workbench 300, so that an air outlet of the centrifugal fan 2 is disposed opposite to the gas collecting channel 1, and an effect that the centrifugal fan 2 jets the gas collecting channel 1 to drive the harmful gas to flow to the gas collecting channel 1 is improved; in this embodiment, first through-hole 301 has been seted up on the mesa of workstation 300, and centrifugal fan 2's air outlet is less than workstation 300's gas vent through first through-hole 301 and accommodation space intercommunication, centrifugal fan 2's air outlet, can increase centrifugal fan 2 to the drive capacity of gas vent exhaust harmful gas, reduce to the harmful gas of diffusion all around. When in use, the centrifugal fan 2 needs to be started in advance.

Alternatively, as shown in fig. 1 and 2, the second air draft unit includes a bellows 4, and the bellows 4 is fixed to the wind shielding assembly, and since the bellows 4 has an advantage of small air intake resistance, the amount of air taken into the bellows 4 by the harmful gas is increased.

Because the harmful gas that is close to the reservation opening position diffuses to all around through the reservation opening more easily, the mouth of blowing of second convulsions unit and the unit of blowing is close to the reservation opening setting, can effectively reduce harmful gas and to the diffusion all around. Specifically, the first wind deflector 3 is provided with a second through hole 31, and the air box 4 is communicated with the accommodating space through the second through hole 31.

Alternatively, as shown in fig. 1 and fig. 2, the gas collecting channel 1 is funnel-shaped, and the large opening end of the gas collecting channel 1 is arranged towards the workbench 300, so as to improve the collection of harmful gas; the small opening end is communicated with the first air draft unit, so that the structure is connected with each other conveniently.

Specifically, first convulsions unit includes the air exhauster, and air exhauster and gas collecting channel 1 intercommunication because the air exhauster has advantages such as the amount of wind is big, the low noise, takes out the harmful gas of gas collecting channel 1 collection through the air exhauster, when effectively taking out harmful gas, avoids producing the noise and endangering relevant personnel. When in use, the exhaust fan needs to be started in advance; specifically, the exhaust fan is communicated with the gas collecting channel 1 through a connecting pipe 6.

The present embodiment further provides a ship, as shown in fig. 1 and 2, which includes a workbench 300 and the gas pumping device, and the gas pumping device is disposed on the workbench 300.

The holding space formed by the wind shielding assembly, the workbench 300 and the gas collecting hood 1 is used for holding substances such as harmful gas generated on the workbench 300, and can prevent the harmful gas from diffusing to the periphery. In the operation process, part of harmful gas automatically drifts into the gas-collecting hood 1; part of harmful gas close to the wind shielding assembly enters a second air draft unit arranged on the side, and the second air draft unit is communicated with a blowing unit, so that the harmful gas enters the blowing unit after passing through the second air draft unit, and the blowing unit blows out the harmful gas and can jet to enable the harmful gas to move to a gas collecting hood 1; harmful gas towards unit one side of blowing probably is not taken away by the second convulsions unit, when the unit of blowing blows, accessible efflux will not be driven to the gas collecting channel 1 in by the gas that the second convulsions unit took away to make harmful gas get into gas collecting channel 1 respectively, finally take out through first convulsions unit, effectively solved harmful gas to the problem of diffusion all around on workstation 300, improved the validity of collecting gas, and then improved and taken out the effect. The blowing unit and the second air draft unit are respectively arranged on two sides of the workbench 300, and can respectively collect gas from two sides of the workbench 300 into the gas collecting hood 1, so that the gas collecting effect is improved, the harm of harmful gas to personnel on the ship is prevented, and the use safety of the ship is improved.

More specifically, as shown in fig. 1 and 2, a deck 100 and a bulkhead 200 are arranged on the ship, and a blowing device and a workbench 300 are fixedly arranged on the deck 100, so that the structure is stably and reliably installed; specifically, the outlet end of the gas collecting channel 1 is arranged away from the bulkhead 200, preventing structural interference while improving the effect of exhausting the gas to the outside by the first exhaust unit.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
