Specifically, as shown in fig. 5, the dust removing assembly includes a back-blowing fan 4, a first check valve 14, a tapered air duct 13, and a second check valve 16; the air outlet end of the back-blowing fan 4 is connected with an air guide shell 9, and the back-blowing fan 4 is arranged on the outer wall of the ventilation shell 1 through the air guide shell 9, the shape of the air guide shell 9 is not limited in the invention, the air guide shell 9 is communicated with a cavity in the ventilation shell 1 below the filter plate 15, the second check valve 16 is arranged in the air guide shell 9, in order to avoid the wind current blown by the draught fan 2 from blowing out of the air guide shell 9 to cause wind mixing, the second check valve 16 is conducted along the blowing direction of the back-blowing fan 4 and is reversely cut off, and the back-blowing fan 4 only plays a role in blowing out and dedusting, so the back-blowing fan 14 can select low power; the conical air duct 13 is distributed in the ventilation shell 1 in a shape of being wide at the top and narrow at the bottom, the conical air duct 13 is arranged above the filter plate 15, the first check valve 14 is arranged at the bottom of the conical air duct 13, and an air outlet 20 is formed in the side wall of the ventilation shell 1 opposite to the side wall provided with the back-blowing fan 4; the wind current that draught fan 2 introduced backs down first check valve 14 through filter 15 through the direction of this toper guide duct 13, the wind current after being filtered by filter 15 blows off from ventilation casing 1 bottom, when the during operation of blowback fan 4, draught fan 2 stops the operation, wind current backs down second check valve 16 and enters into ventilation casing 1 inside and blow to filter 15, first check valve 14 closes this moment, wind current drops the dust anti-blowing on the filter 15 and discharges from air exit 20 along with wind current, the realization is handled and is maintained the deashing of filter 15, and air exit 20 then can be through connecting tube with the air discharge that has the dust to outdoor.

As a preferred embodiment, a step counter bore 18 is formed at an opening at the top of the ventilation housing 1, and the air outlet end of the induced draft fan 2 is fixedly embedded into the step counter bore 18 to realize the sealing installation.

In addition, when the filter plate 15 is subjected to dust removal maintenance, the partition plate 3 needs to shield the air outlet of the ventilation housing 1, so that the partition plate 3 and the ventilation housing 1 are driven by an electric component to open and close.

As shown in fig. 3, the electric component in this embodiment includes a servo motor 10, a guide hook 7 bent inward in a "C" shape, and a rotary rubber wheel 8 connected to the guide hook 7 in a fitting manner; one end of a guide hook 7 is fixed on the side wall of the baffle 3 through a screw 21, a rotating shaft 6 is transversely and fixedly sleeved on the guide hook 7 close to the inward bending section in the middle, the rotating shaft 6 is movably sleeved on two rotating shaft fixing seats 5 at the bottom end of the rear wall of the ventilation shell 1, and the baffle 3 and the guide hook 7 are connected into a whole to rotate together along with the rotating shaft 6; and the base end of servo motor 10 is fixed on the side wall of ventilation housing 1, the output end of servo motor 10 is connected with power shaft 11, the tail end ring of power shaft 11 is distributed with two connecting rods 12, the tail end of each connecting rod 12 is rotatably installed with a rotating rubber wheel 8 for supporting the inner surface of guide hook 7, servo motor 10 drives rotating rubber wheel 8 to rotate by taking connecting rod 12 as the center, guide hook 7 is always in contact with rotating rubber wheel 18 under the action of gravity of baffle 3, rotating rubber wheel 8 can freely rotate, sliding friction between the rotating rubber wheel and the rotating rubber wheel is converted into rolling friction, and therefore abrasion of guide hook 7 is reduced.

In order to realize the intelligent operation of the ventilation device, a controller 19 is arranged on the outer wall of a ventilation shell 1, the signal input end of the controller 19 is connected with an oxygen concentration sensor arranged in a basement, the action range value of the oxygen concentration sensor is set, oxygen in the basement is monitored through the oxygen concentration sensor, when the oxygen concentration in the basement is lower than the lowest limit of a preset range value, the controller 19 receives a signal, the output end of the controller 19 is in control connection with a servo motor 10, and the controller 19 starts an induced draft fan 2 to supply air to the basement.

As shown in fig. 2, the cross section of the baffle 3 is larger than the cross section of the opening at the bottom of the ventilation casing 1, a groove 22 matched with the opening cross section of the ventilation casing 1 is formed in the end face of the baffle 3 contacted with the ventilation casing 1, a circle of sealing strip 17 is arranged in the groove 22, when ash removal maintenance is needed to be carried out on the filter plate 15, the servo motor 10 is started to drive the baffle 3 to rotate to block the bottom of the ventilation casing 1, the back blowing fan 4 introduces air flow into the ventilation casing 1 to complete back blowing to the filter plate 15, and the air flow with dust is finally blown out from the air outlet 20.

Further, the filter plate 15 of the present invention includes a rectangular outer frame, a grid plate disposed in the rectangular outer frame, and a composite fiber filter material clamped between the rectangular outer frame and the grid plate, wherein the grid plate blocks the lint in the air, and the composite fiber filter material filters the fine dust particles in the air.

The invention provides an intelligent ventilation device for building construction, which has the working principle that: install oxygen concentration sensor in the appropriate position of basement, and adopt controller 19 on signal line and the ventilation unit to be connected, when oxygen concentration sensor detects that the inside oxygen concentration of basement is less than the default, to controller 19 signaling, controller 19 starts 2 work of draught fan and supplies air to the inside of basement, support personnel are at the normal activity of basement, after draught fan 2 provides the amount of wind of sufficient volume for the basement is inside, oxygen concentration surpasss oxygen concentration sensor's the upper limit value of predetermineeing, controller 19 control stops draught fan 2, after oxygen concentration is less than predetermineeing the scope value, controller 19 secondary control draught fan 2 moves and supplies air to the basement, so circulation work guarantee basement lasts to have fresh air current. When the dust inside the filter 15 more needs the deashing to maintain, draught fan 2 stops the operation, and servo motor 10 starts the drive and separates baffle 3 and rotate and block up 1 bottom of ventilation casing, then blowback fan 4 blows in the wind stream to ventilation casing 1 inside, and the wind stream upwards flows in ventilation casing 1 and carries out the blowback to filter 15, and the wind stream that has the dust is discharged from air exit 20.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
