Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated cabins, in particular to a prefabricated cabin with a wind and sand proof structure. Background Art

[0002] Economic development has led to new demands for efficiency in power generation. To further shorten the construction cycle, the "factory-based processing and prefabricated construction" model is becoming a trend in power generation. A key component of this approach is the prefabricated cabin. A prefabricated cabin is a carrier for power equipment. Its dimensions meet road transport requirements and can accommodate multiple units of power equipment. Prefabrication is completed in the factory, and after the internal equipment is installed and wired, the cabin is transported to the site of use. The cabin features pressure relief and internal environmental control capabilities. The internal environmental control provides optimal operating conditions for the internal equipment, while the pressure relief function provides excellent explosion protection in the event of a fire.

[0003] Patent (202122182099.X) discloses a prefabricated cabin-type substation for high-altitude photovoltaics, including a substation body, and a cabin roof is provided on the top of the substation body. This prefabricated cabin-type substation for high-altitude photovoltaics has the advantages of being windproof and easy to clean the cabin roof. It solves the problem that in Northwest my country, due to some harsh environmental conditions such as high altitude, strong wind and sand, and a lot of dust, these wind and sand and dust can easily enter the interior of the prefabricated cabin-type substation constructed from the air inlet end of the ventilation and heat dissipation device, thereby affecting the normal operation of the substation. At the same time, the top of the current prefabricated cabin-type substation is generally a flat cabin roof and an inclined flat cabin roof at a certain angle. The two cabin roofs are prone to sand retention and accumulation in a high wind and sand environment, which will cause damage to the cabin roof due to corrosion, so it needs to be cleaned regularly, but the existing cleaning process is more troublesome and inconvenient for the operator to use.

[0004] The ventilation and heat dissipation device of the above-mentioned patent is fixedly connected to the substation body, and does not take into account the need for regular maintenance and replacement of the ventilation and heat dissipation device in the harsh environment of the northwest region (high altitude, strong wind and sand, and a lot of dust). Therefore, during later maintenance and replacement, the ventilation and heat dissipation device cannot be easily removed and installed from the substation body, reducing the practicality of the equipment. At the same time, the local wind and sand volume is large, and the wind and sand net needs to be frequently cleaned or replaced. The wind and sand net in the above-mentioned patent is fixed to a fixed plate, and the fixed plate is fixed to the ventilation and heat dissipation device by bolts. This connection method cannot achieve quick disassembly and installation, reducing the convenience of the equipment. Utility Model Content

[0027] As attached Figure 5 The prefabricated cabin with a wind and sand proof structure shown in the figure includes a fixed frame 50 and a wind and sand proof mesh plate 51. One side of the prefabricated cabin body 1 is fixedly connected to the fixed frame 50 on the left side of the mounting groove 2. The wind and sand proof mesh plate 51 is inserted into the slide groove opened inside the fixed frame 50. The wind and sand proof assembly 5 also includes a limit plate 52. The top of the wind and sand proof mesh plate 51 is fixedly connected to the bottom of the limit plate 52 outside the fixed frame 50. The limit plate 52 is rotatably connected to the front and rear sides with a block 53. The block 53 is connected to the limit plate 52.

[0028] When the sand and dust screen panel 51 needs to be disassembled, cleaned or replaced, the two blocks 53 are rotated outward relative to each other and away from the second slots 54, thereby releasing the fixation of the limit plate 52 and the fixed frame 50. At the same time, the torsion spring 55 is deformed under the force. At this time, the staff pulls the limit plate 52 upward to separate the sand and dust screen panel 51 from the fixed frame 50. During installation, as in the above steps, the sand and dust screen panel 51 is inserted into the fixed frame 50. After that, the blocks 53 on the front and rear sides of the limit plate 52 are driven by the restoring elastic force of the torsion spring 55 to enter the second slots 54, thereby realizing rapid installation and disassembly of the sand and dust screen panel 51 and improving the convenience of the equipment.

[0029] The working principle of the utility model is as follows: when the wind and sand screen plate 51 needs to be disassembled, cleaned or replaced, the two clamping blocks 53 are rotated outwards relative to each other, away from the second clamping slot 54, thereby releasing the fixation of the limit plate 52 and the fixed frame 50. At the same time, the torsion spring 55 is deformed under the force. At this time, the staff pulls the limit plate 52 upward to separate the wind and sand screen plate 51 from the fixed frame 50.

When the ventilation and heat dissipation device 4 needs to be maintained and replaced, the wind and sand screen plate 51 is quickly removed first, and then the pressing plate 63 is pressed. The pressing plate 63 compresses the first spring 65 through the pressing plate 63. The compression of the first spring 65 provides power for the subsequent return of the pressing plate 63. During the movement of the pressing block 62, the trapezoidal groove 67 on its surface and the trapezoidal block 66 gradually tend to the same horizontal line. At this time, the second spring 68 pushes the pushing plate 64 under the force of restoring the deformation. The trapezoidal block 66 enters the trapezoidal groove 67, so that the positioning plate 69 is moved out of the first slot 40 under the drive of the push plate 64, thereby releasing the fixation of the ventilation and heat dissipation device 4. The staff removes the ventilation and heat dissipation device 4 from the prefabricated cabin body 1 through the handle 41 provided on the ventilation and heat dissipation device 4 for maintenance and replacement. When installing it, repeat the above steps and press the pressing block 62 so that the second spring 68 pushes the trapezoidal block 66 into the trapezoidal groove 67 through the push plate 64 under the action of restoring the deformation. At this time, the positioning plate 69 is completely located in the positioning groove 61 Inside, the ventilation and heat dissipation device 4 is placed into the installation groove 2, and then the pressing block 62 is released. The pressing block 62 returns to its initial state under the action of the recovery elastic force of the first spring 65. During the movement of the pressing block 62, the inclined trapezoidal groove 67 passes through the fixing mechanism 6 to realize an outward pushing force on the trapezoidal block 66, pushing the trapezoidal block 66 to move toward the ventilation and heat dissipation device 4, so that the propulsion plate 64 drives the positioning plate 69 to be inserted into the first card slot 40 to fix the ventilation and heat dissipation device 4, thereby realizing the rapid installation and disassembly of the ventilation and heat dissipation device 4 and improving the practicality of the equipment.
