Problems solved by technology
[0004] As far as the current practice is concerned, an independently arranged air supply pipe and an independently arranged exhaust pipe are respectively inserted into the confined space. As a result, the relative positioning of the air supply pipe and the exhaust pipe is not good, and the air supply And the exhaust effect will be affected, and the operation is more inconvenient
[0005] Furthermore, an air outlet end of the air supply pipe extending in the confined space may approach each other with an exhaust end of the exhaust pipe extending in the confined space, so that when the air supply pipe is activated for air supply and the exhaust When the trachea is pumping air, the fresh air sent in may have been drawn back by the exhaust pipe before it can supply air to the confined space, so that the concentration of toxic gases in the confined space cannot be effectively reduced. If the operator There is still a risk of poisoning when unaware and walking straight into a confined space

Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] refer to figure 1 and figure 2 , the first embodiment of the ventilation device of the present invention includes a base 10 , an air supply unit 20 , an exhaust unit 30 , a safety detection alarm unit 40 and a first aid kit 50 .
[0028] The base 10 has an accommodating space 11 and a power supply unit 12 that can be arranged in the accommodating space 11, the power supply unit 12 can supply power to the safety detection and alarm unit 40, and the power supply unit 12 can store electricity type or external power supply type.
[0029] The air supply unit 20 of this embodiment is detachable and connected to the base 10 by using screws or fasteners, and has an air supply fan 21 and an air supply pipe 22 connected to the air supply fan 21 . The blower fan 21 has a blower casing 211 that is hollow cylindrical and has air at both ends, a blower f...

A ventilation apparatus comprises an air supply unit and an exhausting unit, wherein the air supply unit has an air blower and an air supply pipe connected to the air blower, the exhausting unit is connected to the air supply unit and has an air exhausting blower and an air exhausting pipe. The air supply unit is capable of introducing fresh air into a confined space, and the exhausting unit is capable of pumping out harmful gas from the enclosed space or a pipe. Construction safety is ensured. The air supply unit and the exhausting unit are connected to each other, and the the purpose of easy operation is achieved.
Description
technical field [0001] The invention relates to industrial safety equipment, in particular to a ventilation device. Background technique [0002] Gas poisoning incidents often occur, for example, cleaning of chemical storage tanks, construction of underground pipelines... are all manual cleaning and maintenance operations in a confined space. Once toxic volatile gases remain in chemical storage tanks, or underground pipelines If there is methane gas, the operators who clean up and maintain in the confined space may become unconscious instantly due to inhalation of toxic gas, without even having the chance to ask for help from the outside world. [0003] Therefore, it is safer to pump air into the confined space before the operator enters the confined space for cleaning and maintenance operations, and at the same time, introduce fresh air into the confined space to reduce the concentration of toxic gases. And can effectively suppress the unfortunate industrial safety acciden...
