[0002] Large-scale fires and fires in narrow, enclosed spaces such as tunnels and subways are becoming increasingly common. These fires produce large amounts of smoke and dust, posing a significant threat to personnel at the fire scene. When a chemical plant fire occurs, the toxic smoke can change rapidly with the wind direction at the fire scene. Toxic gases may be blown towards rescue personnel as the wind direction changes, affecting their rescue efforts. Therefore, it is necessary to use ultra-high volume smoke exhaust fans for functions such as air supply and smoke exhaust in subway tunnels and large fire scenes, large-scale cooling and dust removal at fire scenes, decontamination of chemical fire scenes, dilution and purification of toxic gases, and changing the wind direction at the fire scene to provide support for the rescue site.

[0006] The technical problem to be solved by this utility model is to provide an integrated ultra-large flow lifting smoke exhaust mechanism, which solves the problem that the smoke exhaust fan of the existing ultra-large air volume smoke exhaust fan is usually fixed and the angle cannot be adjusted.

[0007] This utility model provides an integrated ultra-large flow lifting smoke exhaust mechanism, including a base, a double cross lifter installed on the upper surface of the base, a lifting platform installed above the double cross lifter, a flip plate rotatably mounted on the inner surface of the lifting platform via a hinge, a rectangular groove opened on the upper surface of the lifting platform, a hydraulic push rod fixedly mounted on the inner surface of the lifting platform, a transverse plate mounted on the output end of the hydraulic push rod, connecting rods rotatably mounted on both the left and right sides of the outer surface of the transverse plate, and the other end of the connecting rods rotatably mounted on the outer side of the bottom surface of the flip plate, an electrical distribution box mounted on the left side of the upper surface of the flip plate, and a ventilation duct mounted on the right side of the upper surface of the flip plate, with two sets of fans installed inside the ventilation duct.

[0025] Example:

[0026] like Figures 1-3As shown, an embodiment of this utility model provides an integrated ultra-large flow lifting smoke exhaust mechanism, including a base 1, a double cross lifter 2 installed on the upper surface of the base 1, a lifting platform 3 installed above the double cross lifter 2, a flip plate 4 rotatably mounted on the inner surface of the lifting platform 3 via a hinge, a rectangular groove 301 opened on the upper surface of the lifting platform 3, a hydraulic push rod 5 fixedly mounted on the inner surface of the lifting platform 3, a transverse plate 6 mounted on the output end of the hydraulic push rod 5, connecting rods 7 rotatably mounted on both the left and right sides of the outer surface of the transverse plate 6, and the other end of the connecting rod 7 rotatably mounted on the outer side of the bottom surface of the flip plate 4, an electrical distribution box 8 installed on the left side of the upper surface of the flip plate 4, and a duct 9 installed on the right side of the upper surface of the flip plate 4, with two sets of fans 10 installed inside the duct 9.

[0027] By incorporating a double cross lifter 2, the horizontal height of the lifting platform 3 can be easily adjusted, thereby achieving the effect of adjusting the horizontal height of the fan 10. By incorporating a hydraulic push rod 5, the hydraulic push rod 5 pushes the transverse plate 6 to slide inward and outward, and supports the tilting plate 4 through the connecting rod 7, making it convenient for the tilting plate 4 to rotate along the lifting platform 3 via the hinge, thereby achieving the effect of adjusting the tilt angle of the fan 10 and increasing the ease of use.

[0028] In this embodiment, the upper surface of the base 1 and the bottom surface of the lifting platform 3 are provided with storage slots for storing the double cross lifting device 2. When the double cross lifting device 2 is retracted to its minimum length, the bottom surface of the lifting platform 3 is in close contact with the upper surface of the base 1, making it convenient for the lifting platform 3 to be stored on the upper surface of the base 1.

[0029] In this embodiment, the length of the connecting rod 7 is less than the width of the rectangular groove 301, and when the hydraulic push rod 5 is retracted to its minimum length, the connecting rod 7 is horizontally stored in the rectangular groove 301, and the flip plate 4 is horizontally attached to the upper surface of the lifting platform 3, so that the flip plate 4 can be horizontally stored on the upper surface of the lifting platform 3.

[0030] In this embodiment, there is a distance between the two sets of fans 10, and there is a distance between the sides of the two sets of fans 10 and the inner surface of the air duct 9. The fans 10 are rotatably mounted on the air duct 9 via pins 901. A gear 902 is fixedly mounted above the pins 901. An adjustment assembly for adjusting the angle of the fans 10 is installed on the air duct 9. The adjustment assembly includes a mounting block 11, an adjustment screw 1101, a toothed plate 1102, and a rotating wheel 1103. The mounting block 11 is fixedly mounted on the air inlet end of the upper surface of the air duct 9. The adjustment screw 1101 is threadedly connected to the mounting block 11. The toothed plate 1102 is rotatably mounted on the inner end of the adjustment screw 1101 via a bearing. The rotating wheel 1103 is fixedly mounted on the outer end of the adjustment screw 1101.

[0031] In this embodiment, the bottom surface of the toothed plate 1102 is in close contact with the upper surface of the air duct 9.

[0032] In this embodiment, the left and right sides of the toothed plate 1102 are provided with locking teeth that match the gears 902, and the locking teeth on the left and right sides of the toothed plate 1102 respectively mesh with the two gears 902.

[0033] By configuring a pin 901, a gear 902, and an adjustment assembly, rotating the rotating wheel 1103 causes the adjusting screw 1101 to rotate. The adjusting screw 1101 drives the toothed plate 1102 to move along the upper surface of the air duct 9 in the inward and outward directions. The toothed plate 1102 drives the gear 902 and the pin 901 to rotate, thereby achieving the effect of driving the two fans 10 to rotate. This makes the two fans 10 form an inverted V-shape, which is convenient for the two fans to concentrate on exhausting air or disperse blowing air, further increasing the convenience of use.

[0034] In this embodiment, universal wheels 101 are fixedly installed at the four corners of the bottom surface of the base 1, and an installation groove 102 is opened in the center of the bottom surface of the base 1. An electric telescopic rod 103 is installed on the inner side of the installation groove 102, and a support plate 104 is fixedly installed on the bottom surface of the electric telescopic rod 103.

[0035] In this embodiment, when the electric telescopic rod 103 is extended to its minimum length, the bottom horizontal height of the support plate 104 is higher than the bottom horizontal height of the caster wheel 101. When the electric telescopic rod 103 is extended to its maximum length, the bottom horizontal height of the support plate 104 is equal to the bottom horizontal height of the caster wheel 101.

[0036] With the universal wheels 101 installed, the universal wheels 101 roll on the ground, which facilitates the movement of the base 1. When the base 1 needs to be positioned, the electric telescopic rod 103 extends. When the electric telescopic rod 103 extends to its maximum length, the support plate 104 contacts the ground, ensuring the stability of the base 1 when it is placed.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
