Korean Patent No. 10-0711603 (registered on Apr. 19, 2007), "sewage pipe manhole with ventilation device" is introduced.

The sewage pipe manhole to which the ventilation device is attached has a circular seating groove formed at the center of the upper surface thereof, a first fastening hole formed at the center of the seating groove, and a plurality of second fastening holes formed at the outer side of the first fastening hole. A lid; A solar cell plate formed in a circular plate shape and having a plurality of solar cells mounted on an upper surface thereof, a fastening bolt protruding from a central portion of the bottom surface thereof and seated in a seating groove of the manhole cover to fasten the fastening bolts to the first fastening holes; A battery is inserted to charge a power source supplied from a solar cell of the solar cell plate, a power source charged in the battery is operated, and a flange is formed on an upper end outer periphery to be engaged with a second fastening hole of the manhole cover motor; And a rotary vane bolted to the rotary shaft of the motor and rotated according to the rotation of the motor.

However, the sewer manhole to which the ventilation device is attached is continuously exposed to a harsh environment inside the manhole, so that it is likely to be damaged or broken by corrosion, etc., and the height of the manhole cover is the same as that of the ground, Therefore, there is a disadvantage that self-power generation through sunlight is substantially difficult.

In addition, the manhole in which the electric wire is embedded rather than the sewer manhole can not remove the toxic gas in the same manner as the above-mentioned technique because there is no sewer to which natural gas is discharged.

Therefore, it is an object of the present invention to provide an air conditioner which is light in weight and easy to carry, and can be easily installed in a manhole by pulling out a mounting stand mounted on the housing, and the ventilator is driven by battery power, It is an object of the present invention to provide a portable manhole gas ejector that can facilitate the worker working in a manhole and can prevent a choking accident.

According to an aspect of the present invention, there is provided a portable manhole gas ejector comprising: a housing having a triangular shape having three curved side surfaces, a mounting hole formed at a center of the housing, The power supply controller is mounted on the upper surface of the housing, the battery power supply is electrically connected to the power supply controller by electric wires, the operation of the fan is controlled by the power controller, and the flexible duct is connected to the housing, Wherein the housing is formed with three receiving portions so that the receiving portion is formed in a curved shape along the curved side surface on the inside of the curved side surface, a curved holding table is detachably mounted on each receiving portion, And an opening portion of the accommodating portion is formed on the side surface, And, the incision portion is formed to extend along a curved side, it characterized in that the knob on the holder through which the incision portion protrudes to the outside.

The housing and the ventilator are formed of a plastic material, and the flexible duct is formed in a bellows shape so that the length of the flexible duct can be adjusted.

Accordingly, the portable manhole gas ejector according to the present invention can be easily installed on the manhole by pulling out the cradle mounted on the housing, and the ventilator is driven by the battery power, Thus, the convenience of the operator working in the manhole can be improved, and it is possible to prevent the choking accident.

1 is a block diagram showing a portable manhole gas ejector according to the present invention.
2 and 3 are perspective views illustrating a portable manhole gas ejector according to the present invention. FIG. 2 is a state in which a cradle is pulled into a receiving portion of a frame, and FIG. 3 is a state in which a cradle is pulled out from a receiving portion of the frame.
FIG. 4 is a plan view of the portable manhole gas ejector of FIG. 3;
FIG. 5 is a schematic view illustrating a portable manhole gas ejector according to an embodiment of the present invention taken in a manhole to explain how the manhole is ejected. FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 to 4, a portable manhole gas ejector according to the present invention includes a housing 10 having a triangular shape having three curved side surfaces 12, a mounting hole 14 formed at the center of the housing 10, A fan 20 is mounted on the mounting hole 14 of the housing 10 and a power controller 30 is mounted on the upper surface of the housing 10 so that the power controller 30 is connected to the battery power source 40 are electrically connected to each other by the electric wire 41 so that the operation of the fan 20 is controlled by the power controller 30 and the flexible duct 50 is connected to the housing 10, The upper end of the flexible duct 50 is connected and three accommodating portions 16 are formed in the housing 10 so that the accommodating portion 16 is curved along the curved side on the inside of the curved side surface, A curved holding table 60 is detachably mounted on the receiving portion 16 and a cut portion 18 and a receiving portion 16 are provided on the curved side surface 12. [ The cutout 18 is formed long along the curved side face 12 and the knob 65 of the cradle 60 is formed to be longer than the curved side face 12, And protrudes outward through the cutout 18.

The housing 10 and the ventilator 20 are formed of a plastic material, and the flexible duct 50 is formed into a bellows shape so that the length of the flexible duct 50 can be adjusted.

Referring to FIG. 5, the portable manhole gas ejector constructed as described above is installed and operated in a manhole as follows.

The holder 60 is pulled out from the housing 10 and the holder 60 is put around the manhole 70. [ The lower end of the flexible duct 50 is lowered to the bottom surface of the manhole 70 and the operation of the ventilator 20 is controlled by connecting the battery power source 40 to the power source controller 30. At this time, the holder 60 can be easily taken out from the housing receiving portion 16 by using the knob 65 projected from the curved side surface 12 of the housing 10. When the ventilator 20 is operated, air and noxious gas are discharged to the manhole 70 through the flexible duct 50 in the vicinity of the bottom surface of the manhole 70 by the ventilator 20.

The portable manhole gas ejector according to the present invention as described above has a structure in which the housing 10 and the ventilator 20 are made of a light plastic material so that they are light and easy to carry and draw out the cradle 60 mounted on the housing 10, Since the ventilator 20 can be easily installed in the ventilator 70 and the problem of ventilating the ventilator can be easily solved by operating the ventilator 20 by the battery power source, the convenience of the operator working in the manhole can be improved, have.
