[0002] In modern industrial and infrastructure construction, prefabricated cabins have been widely used as an efficient and convenient space for equipment integration and use. Prefabricated cabins are typically used to store various electrical equipment, control devices, etc. To ensure the normal operation of the equipment inside the cabin and the safety of the operators, good ventilation is essential.

[0003] Traditional prefabricated cabin ventilation systems present numerous challenges in installation and disassembly. Firstly, the installation process is often complex, requiring various tools such as screwdrivers and wrenches. This not only increases time and labor costs but also significantly limits installation in challenging environments, such as when tools are scarce or personnel cannot easily carry a large number of tools. Secondly, the complex installation structure makes disassembly cumbersome when cleaning or maintenance is needed. Frequent disassembly and installation can damage connections, reducing the system's lifespan. Furthermore, improper disassembly can damage the prefabricated cabin's structure, affecting its overall performance and sealing.

[0004] Therefore, a new ventilation device for prefabricated cabins that is easy to disassemble and clean is proposed to solve the above problems. 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 embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a ventilation device for prefabricated cabins that is easy to disassemble and clean.

[0029] Please see Figure 1-6 As shown, this embodiment is a ventilation device for a prefabricated cabin that is easy to disassemble and clean. It includes a prefabricated cabin 110, on which a ventilation opening is provided. A connecting groove 112 is provided on the ventilation opening. Two mounting cylinders 130 are installed at both ends of the connecting groove 112. A telescopic rod 131 is installed on each of the mounting cylinders 130. The end of the telescopic rod 131 near the mounting cylinder 130 is installed inside the mounting cylinder 130. A first connecting hole 120 is provided at the bottom end of each mounting cylinder 130. Two second connecting holes 121 are provided at both ends of the inner sidewall of the ventilation opening. A locking rod 122 is installed in each of the second connecting holes 121. An installation frame 210 is installed at the upper end of the prefabricated cabin 110. Locking holes 280 are provided at both ends of the installation frame 210. The diameter of each locking hole 280 is equal to that of the corresponding second connecting hole 121. Nitrogen gas is provided in the first connecting hole 120 and the second connecting hole 121.

[0030] The prefabricated cabin 110 has a first mounting groove 111 at its upper end. An air pump 154 ​​is installed at the bottom of the inner side wall of the first mounting groove 111. A control button 154 is installed at the upper end of the air pump 154. The output end of the control button 154 is connected to the input end of the air pump 154. Any one of the second connection holes 121 is connected to the air pump 154. This design allows the air pump 154 ​​to remove nitrogen from the first connection hole 120 and the second connection hole 121 when disassembly is required. When the nitrogen disappears, the internal air pressure decreases, and the locking rod 122 disengages from the locking hole 280. At this time, the mounting frame 210 can be easily detached from the mounting base.

[0031] The mounting slot 111 has a second sliding slot 150, and the first sliding slot 140 has a protective plate 151 installed in it. The protective plate 151 has a handle 152 installed at the end away from the air pump 154. This design can protect the air pump 154 ​​when it is not in use, and can also effectively prevent dust from entering it.

[0032] The connecting groove 112 has a first sliding groove 140 at both ends, and the mounting frame 210 has two sliders 230 at both ends. Each slider 230 is engaged with the corresponding first sliding groove 140. This design can effectively prevent the other end from being outside the prefabricated compartment 110 after one end is installed into the mounting frame 210, and can avoid the locking rod 122 from breaking when it is placed at an angle.

[0033] An installation column 220 is installed inside the installation frame 210. Multiple sets of bearings 240 are installed on the installation column 220. A rotating column 250 is installed inside any set of bearings 240. Blades 260 are installed at both ends of the rotating column 250. The rotating column 250 is driven by a motor. This design adopts a louver design, and the rotation angle of the blades 260 can be controlled by the motor, thereby achieving rapid adjustment of the ventilation volume.

[0034] Each louver 260 is equipped with multiple layers of electrostatic adsorption film 270, which uses electrostatic attraction to adsorb fine particles such as dust from the air. During ventilation, when airflow carrying dust passes through the louvers, the electrostatic adsorption film actively adsorbs the dust, greatly improving the filtration effect of the ventilation device. Moreover, cleaning is easier because the dust is mainly concentrated on the electrostatic adsorption film. A removable electrostatic adsorption film 270 can be used; once a certain amount of dust has been adsorbed, the film can be simply peeled off and replaced, eliminating the need for complex cleaning of the entire louver.

[0035] Working principle: When the mounting frame 210 needs to be installed, the four sliders 230 at the left and right ends of the mounting frame 210 are aligned with the first sliding groove 140 respectively, and then it is lowered. When the mounting frame 210 moves downward, it will squeeze the four telescopic rods 131 in the connecting groove 112 into the corresponding mounting cylinder 130. When the telescopic tubes squeeze the space in the mounting cylinder 130, they will squeeze nitrogen from the first connecting hole 120 into the second connecting hole 121, and squeeze the locking rod 122 into the locking hole 280, thereby fixing the mounting frame 210 tightly. When disassembly is required, the control button 154 is pressed directly, so that the air pump 154 ​​extracts the nitrogen in the first connecting hole 120 and the second connecting hole 121. When the internal air pressure decreases, the locking rod 122 retracts from the corresponding locking hole 280, and the disassembly operation is completed.

[0036] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
