It is impossible to control the opening and closing of the vents and the adjustment of the size of the vents. Therefore, the ventilation volume cannot be adjusted according to actual needs, which brings certain limitations to the use effect of the air tower. Therefore, in response to market demand, an adjustable ventilation air tower structure is proposed. Utility Model Content

DETAILED DESCRIPTION

[0018] Secondly, the present invention is described in detail with reference to the schematic diagram.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Figure 1-Figure 2 The following is a schematic diagram of the entire structure of an adjustable ventilation air tower structure of the utility model. Figure 1-Figure 2 , an adjustable ventilation air tower structure of the present embodiment includes a supporting main frame 100 fixed on both sides of the roof vent, a cross frame 110 is connected and fixed to the top of the supporting main frame 100, a rain shield 200 with return water slopes on both sides is installed on the upper end of the cross frame 110, and also includes a surrounding plate 300 arranged at the outermost side of the ventilation air tower and fixedly installed with the supporting main frame 100, and side air vents 310 are provided on both sides of the bottom of the surrounding plate 300 and at the edges of both sides of the roof vent, a valve plate 400 is arranged parallel to and located directly above the roof vent below the cross frame 110, and the valve plate 400 is vertically slidably connected to the cross frame 110, a servo motor 500 is arranged on the upper end of the cross frame 110, a threaded screw 510 is vertically connected to the output shaft end at the bottom of the servo motor 500, and the threaded screw 510 and the valve plate 400 are threadedly connected.

[0021] The supporting main frame 100 also has support ribs 120 on both sides for fixing the supporting enclosure 300, and a reinforcing beam 130 is fixedly connected between the bottom of the supporting main frame 100. Here, the supporting main frame 100 is the main supporting frame of the ventilation air tower, and its bottom is fixedly installed on the roof. At the same time, the supporting ribs 120 are not limited to a specific number. The purpose is to stabilize the enclosure 300, and the reinforcing beam 130 at the bottom can further enhance the overall rigidity and use stability of the supporting main frame 100 and the air tower skeleton system; there are also wind guide channels between the lower inclined ends on both sides of the rain shield 200 and the inner side of the enclosure 300. The rain shield 200 can also discharge rainwater laterally through the wind guide channel, and flow down to the roof through the enclosure 300 to achieve the effect of ventilation and drainage. This is a conventional structure in the field of ventilation air towers and will not be elaborated in detail.

[0022] A skylight 320 is also provided in the center of the top of the enclosure 300 along its length direction. The skylight 320 is connected to the side air vents 310 and the roof vents through air guide channels. The working principle of the ventilation air tower is utilized to form heat pressure or wind pressure through the cooperation of the skylight 320, the side air vents 310 and the roof vents, thereby promoting indoor and outdoor air circulation and achieving the effect of indoor ventilation circulation in the factory building.

[0023] A nut 520 matching the thread of the threaded screw 510 is also fixed at the center of the valve plate 400. Here, the nut 520 can adopt, for example, a ball-type thread, which has the characteristics of high adjustment accuracy, strong load-bearing performance, and good static locking performance. It is suitable for the technical measures used to lift the valve plate 400 in this device, so that the valve plate 400 is more stable when it is lifted; and during the lifting process, when the valve plate 400 rises, the ventilation volume of the roof vent will increase, and vice versa, it will decrease, thereby achieving the effect of ventilation volume regulation.

[0024] Sleeves 610 are fixed on both sides of the valve plate 400, and a guide rod 600 is vertically slidably matched inside the sleeve 610, and the upper end of the guide rod 600 is fixedly installed with the cross frame 110, and the bottom of the two guide rods 600 is connected to a base plate 700. Through the cooperation of the guide rod 600, the sleeve 610 and the base plate 700, the valve plate 400 is more stable during the lifting process, and the rotational force of the threaded screw 510 can be converted into a linear driving force, so that the valve plate 400 can be lifted and lowered smoothly.

[0025] Furthermore, a bearing seat 530 rotatably mounted to the lower end of the threaded screw 510 is provided at the center of the base plate 700. The cooperation between the base plate 700 and the bearing seat 530 can further improve the stability of the threaded screw 510.

[0026] It should be noted that the length of the valve plate 400 in this embodiment matches the actual size of the ventilation tower. If the valve plate 400 is longer, two or more lifting drive units can be set in the length direction of the valve plate 400 to allow the valve plate 400 to form a stable up and down movement.

[0027] In summary, in the adjustable ventilation air tower structure of the present embodiment, when the ventilation volume of the roof vent needs to be adjusted, the threaded screw 510 is driven to rotate by the servo motor 500, and the valve plate 400 is driven to rise or fall with the cooperation of the nut 520, the guide rod 600 and the sleeve 610. The higher the valve plate 400 is raised, the greater the ventilation volume of the roof vent becomes, and vice versa, if it is lowered, the ventilation volume will be compressed, which effectively solves the problem that the traditional ventilation air tower cannot adjust the ventilation volume according to actual needs, and improves the practicality and applicability of the ventilation air tower.

[0028] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
