Description

Technical Field

[0001] This utility model relates to the technical field of air handling unit installation equipment, specifically a base for roof mounting of an air handling unit. Background Technology

[0002] With increasing urban building density and stricter energy conservation and environmental protection requirements, air handling units are widely used in ventilation and air conditioning systems in commercial buildings, industrial plants, and other locations. To save floor space and optimize airflow, many air handling units are installed on building rooftops. This installation method not only reduces the space occupied by the equipment but also improves air handling efficiency and reduces energy consumption.

[0003] The shortcomings of existing technology:

[0004] Currently, air handling units are typically installed on concrete roofs using expansion bolts for direct fixing. While this method is simple in structure and low in cost, it has significant drawbacks in practical applications. Due to the strong winds on rooftops, especially in high-rise buildings where crosswinds are a major concern, strong winds can cause significant swaying of the air handling unit. Furthermore, the stress on the expansion bolts on the windward side of the unit increases with the wind force. This prolonged wind load can lead to bolt fatigue, even breakage or loosening, affecting the normal operation of the equipment and potentially posing a safety hazard at height. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified. Example

[0032] Please see Figure 1-5 As shown, this utility model provides a technical solution for a roof-mounted base for an air handling unit: A roof-mounted base for an air handling unit includes a base plate 1. A base body 2 for mounting the air handling unit is mounted on the upper surface of the base plate 1. Several positioning terminals are provided on the upper surface of the base body 2 for connecting and fixing with the air handling unit. A stabilizing mechanism 3 is installed inside the base body 2. A trigger component 4 for controlling the activation of the stabilizing mechanism 3 is installed on the upper end of the base body 2. A controller 5 is also embedded in the upper end of the base body 2.

[0033] The stabilizing mechanism 3 includes a motor 301, a counterweight 303, a telescopic plate 304, and a sensing strip 306. The motor 301 is centrally mounted on the inner wall of the base body 2 via a bracket, and a connecting shaft 302 is installed at the output end of the motor 301. The counterweight 303 is movably mounted inside the base body 2, with one side connected to the connecting shaft 302. The motor 301 drives the counterweight 303 to rotate within the base body 2 around the output shaft of the motor 301, adjusting the overall center of gravity of the base body 2. The telescopic plate 304 is circumferentially formed in a groove on the side wall of the base body 2. An electromagnet 305 is mounted on the side wall of the base body 2, located outside the telescopic plate 304. A permanent magnet matching the electromagnet 305 is mounted at the end of the telescopic plate 304. The sensing strip 306 is fixedly mounted on the side wall of the counterweight 303, and a proximity sensor 307 matching the sensing strip 306 is mounted on the inclined surface at the end of the telescopic plate 304.

[0034] When wind blows towards the air handling unit from a certain direction, the force on the air handling unit causes the center of gravity of the base body 2 to shift under the action of the wind. The stress on the bolts connecting the unit to the ground on the windward side increases significantly with the increase of wind force. At this time, the triggering component 4 is triggered. The controller 5 first controls the electromagnet 305 to be energized, so that the electromagnet 305 on the windward side of the base generates a repulsive force on the telescopic plate 304, pushing it out of the slide groove, while the other electromagnets 305 generate an attractive force on the telescopic plate 304, keeping it in the slide groove. Then, the controller controls the motor 301 to start, and the motor 301 drives the counterweight 303 to rotate until the sensing strip 306 comes into close contact with the corresponding proximity sensor 307. After receiving the signal from the proximity sensor 307, the controller 5 shuts off the motor 301. At this time, the counterweight 303 is located on the windward side of the base body 2 and the air handling unit, and the center of gravity has also shifted to this location.

[0035] By using the stabilizing mechanism 3, a counterweight 303 is added inside the base. When the wind is strong, the counterweight 303 is moved to the windward side to adjust the center of gravity, reducing or even eliminating the swaying of the base plate 1 on the windward side of the equipment relative to the roof. The stress on the connecting bolts is also reduced or even eliminated accordingly, which significantly improves the stability of the connection between the base plate 1 and the roof concrete. Furthermore, the position of the counterweight 303 inside the base body 2 can be adjusted according to the actual wind direction, making it more adaptable and practical. This ensures the normal operation of the equipment and eliminates potential safety hazards.

[0036] The trigger assembly 4 includes a mounting slot 401 and a fan rod 403. The mounting slot 401 is circumferentially formed at the outer edge of the upper surface of the base body 2. A touch switch 402 is fixedly installed on the inner side of the mounting slot 401. The number of touch switches 402 is the same as the number of proximity sensors 307. The controller 5 controls a set of electromagnets 305 and proximity sensors 307 through one touch switch 402. The fan rod 403 is rotatably connected in the mounting slot 401, and a return spring 404 connects the fan rod 403 and the mounting slot 401.

[0037] When wind blows towards the air handling unit from a certain direction, the wind vane 403 on that side, propelled by the wind, overcomes the spring force of the return spring 404 and rotates until it triggers the touch switch 402. The touch switch 402 then sends an electrical signal to the controller 5, which in turn controls the stabilizing mechanism 3 to adjust. The controller 5 determines the wind direction based on the position of the triggered touch switch 402, thereby controlling the motor 301 and electromagnet 305 to move the counterweight 303 to the windward side. Under normal circumstances, multiple touch switches 402 should be triggered simultaneously, and the controller 5 should use the electrical signal from the touch switch 402 located in the middle as the trigger.

[0038] By triggering component 4, the controller 5 can accurately judge the wind direction in various directions, thereby autonomously starting and driving the counterweight 303 to adjust its position in strong winds. This reduces the reliance on manual operation and further improves the adaptability and practicality of the base.

[0039] Ball grooves 201 are provided on the upper and lower end faces inside the base body 2. The upper and lower ends of the counterweight 303 are connected to the ball grooves 201 by rolling balls. The rolling connection can significantly reduce the friction force on the counterweight 303 when it moves, and also improve the stability of the counterweight 303 when it moves.

[0040] The proximity sensor 307 is movably mounted in the mounting hole on the telescopic plate 304 via a buffer spring. If the counterweight 303 fails to stop in time due to inertia and comes into contact with the proximity sensor 307, the proximity sensor 307 can retract into the telescopic plate 304 for self-protection. If the force on the telescopic plate 304 is greater than the repulsive force of the electromagnet 305, it will also retract into the groove.

[0041] The controller 5 is electrically connected to the motor 301, the electromagnet 305, the proximity sensor 307, and the touch switch 402 via wires. The controller 5 receives electrical signals from the proximity sensor 307 and the touch switch 402 via wires and controls the operation of the motor 301 and the electromagnet 305.

[0042] The end of the wind rod 403 is hemispherical. The hemispherical shape is greatly affected by wind force, which can improve the trigger sensitivity of the touch switch 402.

[0043] The working principle of this utility model is as follows:

[0044] When wind blows towards the air handling unit from a certain direction, the wind vane 403 on that side, propelled by the wind, overcomes the spring force of the return spring 404 and rotates until it triggers the touch switch 402. The touch switch 402 then sends an electrical signal to the controller 5. The controller 5 then energizes the electromagnets 305, causing the electromagnets 305 on the windward side of the base to exert a repulsive force on the telescopic plate 304, pushing it out of the slide groove. The other electromagnets 305 exert an attractive force on the telescopic plate 304, keeping it within the slide groove. Next, the controller starts the motor 301, which drives the counterweight 303 to rotate until the sensing strip 306 comes into contact with the corresponding proximity sensor 307. Upon receiving the signal from the proximity sensor 307, the controller 5 shuts off the motor 301. At this point, the counterweight 303 is located on the windward side of the base body 2 and the air handling unit, and the center of gravity shifts to this location. The stress on the connecting bolts on the windward side of the equipment is reduced or even eliminated.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
