Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Example 1

[0027] The utility model provides a preferred embodiment of a construction engineering HVAC fire protection smoke exhaust pipe structure. Figure 1-4 As shown: A construction engineering HVAC fire smoke exhaust pipe structure, including a support frame 1, a fixed base 2, and a smoke exhaust pipe 6.

The inner wall of the smoke exhaust pipe 6 is equidistantly provided with arc-shaped sliding openings on both sides. The interior of the smoke exhaust pipe 6 is provided with a cavity, which is connected to the arc-shaped sliding opening. A fixing component 4 is provided between the support frame 1 and the smoke exhaust pipe 6. A cooling component 5 is provided inside the smoke exhaust pipe 6. The fixing component 4 includes: an L-shaped support plate 411, symmetrically fixedly installed on the surface of the support frame 1; a threaded rod 412, movable The top of the L-shaped support plate 411 is connected to the bottom end of the threaded rod 412 through a bearing, and the top of the threaded rod 412 is fixedly installed with a limit plate 413, and the top of the limit plate 413 is fixedly installed with a rotating block 414. The outer wall of the threaded rod 412 is threadedly connected with a movable plate 415, and the bottom of the movable plate 415 is symmetrically installed with a guide rod 416. The bottom end of the guide rod 416 movably passes through the top of the L-shaped support plate 411 and extends to the bottom of the L-shaped support plate 411, and is fixedly installed with a fixed clamping plate 417, and the bottom of the fixed clamping plate 417 is fixedly installed with a rubber pad 418.

[0028] Furthermore, in the embodiment, the threaded rod 412 is driven to rotate by rotating the rotating block 414. Since the threaded rod 412 is threadedly connected to the movable plate 415, and the guide rod 416 at the bottom of the movable plate 415 restricts it from moving up and down, when the threaded rod 412 rotates, the movable plate 415 moves downward along the threaded rod 412. When the movable plate 415 moves downward, it drives the guide rod 416 and the fixed clamping plate 417 at the bottom to move downward. The rubber pad 418 at the bottom of the fixed clamping plate 417 contacts the smoke exhaust pipe 6, clamping and fixing the smoke exhaust pipe 6.

[0029] Example 2

[0030] On the basis of Example 1, the present invention provides a preferred embodiment of a construction engineering HVAC fire smoke exhaust pipe structure. Figure 1-4 As shown: the cooling component 5 includes: a spraying component 51, which is arranged inside the smoke exhaust pipe 6; a driving component 52, which is arranged on one side of the spraying component 51; the spraying component 51 includes: a water tank 511, which is fixedly installed on the top of the smoke exhaust pipe 6; a heat insulation layer 513, which is arranged inside the smoke exhaust pipe 6; the front of the water tank 511 is connected to a water inlet pipe 512, and the bottom of the water tank 511 is connected to a water outlet pipe 514, the other end of the water outlet pipe 514 passes through the top of the outer wall of the smoke exhaust pipe 6 and extends to the top of the inner wall of the smoke exhaust pipe 6, and is connected to a pump 515, the output end of the pump 515 is connected to a connecting pipe 516, the other end of the connecting pipe 516 movably passes through the bottom of the inner wall of the smoke exhaust pipe 6 and extends to the bottom of the outer wall of the smoke exhaust pipe 6, and is connected to a connecting transverse pipe 519, and the bottom of the connecting transverse pipe 519 is equidistantly connected to nozzles 5111.

[0031] Furthermore, in the embodiment, when the smoke exhaust pipe 6 needs to be cooled, the pump 515 is started to pump out the water in the water tank 511 through the outlet pipe 514. The water enters the pump 515 through the outlet pipe 514. The pump 515 pressurizes the water and transports it to the connecting cross pipe 519 through the connecting pipe 516. The nozzle 5111 at the bottom of the connecting cross pipe 519 evenly sprays the water inside the smoke exhaust pipe. The insulation layer 513 can reduce the heat transfer to the outside and improve the cooling effect. The sprayed water comes into contact with the high-temperature flue gas and absorbs the heat of the flue gas, thereby reducing the temperature inside the smoke exhaust pipe.

[0032] Example 3

[0033] On the basis of Examples 1 and 2, the present invention provides a preferred embodiment of a construction engineering HVAC fire smoke exhaust pipe structure. Figure 1-4As shown: the driving component 52 includes: a connecting rod 521, which is symmetrically fixedly mounted on both ends of the connecting cross pipe 519; a fixed plate 522, which is fixedly mounted on one side of the inner wall of the smoke exhaust pipe 6; a motor 523, which is fixedly mounted on the outer side of the fixed plate 522; the other end of the connecting rod 521 passes through the arc-shaped sliding opening and is slidably connected to the smoke exhaust pipe 6 through the arc-shaped sliding opening, and the output end of the motor 523 is provided with a reciprocating screw rod 524, the other end of the reciprocating screw rod 524 movably passes through the outer side of the fixed plate 522 and the inner side of the fixed plate 522, and extends to the inner side of the other fixed plate 522, and is rotatably connected to the fixed plate 522 through a bearing, the outer wall of the reciprocating screw rod 524 is threadedly connected to a movable block 525, and a connecting base plate 526 is fixedly mounted on the top of the connecting base plate 526, and limiting rods 527 are symmetrically and equidistantly installed on the top of the connecting base plate 526, and a connecting rod 521 is movably connected between the two limiting rods 527.

[0034] Furthermore, in the embodiment, after the motor 523 is started, the reciprocating screw 524 is driven to rotate, and the movable block 525 threadedly connected to the reciprocating screw 524 performs reciprocating linear motion under the rotation of the reciprocating screw 524. The connecting base plate 526 on the top of the movable block 525 is connected to the connecting rod 521 through the limiting rod 527, and the connecting rod 521 is fixedly connected to the connecting cross pipe 519. When the movable block 525 moves, the connecting rod 521 is driven to slide in the arc-shaped sliding opening through the connecting base plate 526 and the limiting rod 527, thereby driving the connecting cross pipe 519 to move back and forth in the smoke exhaust duct 6. The movement of the connecting cross pipe 519 enables the nozzle 5111 to spray water more evenly, thereby improving the cooling effect.

[0035] When in use, the threaded rod 412 is driven to rotate by rotating the rotating block 414. Since the threaded rod 412 is threadedly connected to the movable plate 415 and the guide rod 416 at the bottom of the movable plate 415 restricts it from moving up and down, when the threaded rod 412 rotates, the movable plate 415 moves downward along the threaded rod 412. When the movable plate 415 moves downward, the guide rod 416 and the fixed clamping plate 417 at the bottom are driven to move downward. The rubber pad 418 at the bottom of the fixed clamping plate 417 contacts the smoke exhaust pipe 6. The smoke exhaust pipe 6 is clamped and fixed, and the rubber pad 418 increases friction and protects the smoke exhaust pipe 6. By adjusting the position of the fixed clamping plate 417, it can adapt to smoke exhaust pipes 6 of different sizes to ensure the stable installation of the smoke exhaust pipe 6 on the support frame 1. The water tank 511 is used to store cooling water. When the smoke exhaust pipe 6 needs to be cooled, the pump 515 is started to pump the water in the water tank 511 out through the outlet pipe 514. The water enters the pump 515 through the outlet pipe 514. The pump 515 pressurizes the water and transports it to the connecting cross pipe 519 through the connecting pipe 516. The nozzle 5111 at the bottom of the connecting cross pipe 519 sprays the water evenly inside the exhaust pipe. The heat insulation layer 513 can reduce the heat transfer to the outside and improve the cooling effect. The sprayed water contacts the high-temperature flue gas and absorbs the heat of the flue gas, thereby reducing the temperature inside the exhaust pipe. After the motor 523 is started, it drives the reciprocating screw 524 to rotate. The movable block 525 threadedly connected to the reciprocating screw 524 rotates when the reciprocating screw 524 rotates. The movable block 525 makes reciprocating linear motion downward, and the connecting base plate 526 on the top of the movable block 525 is connected to the connecting rod 521 through the limit rod 527. The connecting rod 521 is fixedly connected to the connecting cross pipe 519. When the movable block 525 moves, the connecting base plate 526 and the limit rod 527 drive the connecting rod 521 to slide in the arc-shaped sliding opening, thereby driving the connecting cross pipe 519 to move back and forth in the smoke exhaust duct 6. The movement of the connecting cross pipe 519 enables the nozzle 5111 to spray water more evenly, thereby improving the cooling effect.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
