Description

Technical Field

[0001] This utility model relates to the field of mechanical design technology, specifically to a ventilation and filtration device for prefabricated power equipment cabins. Background Technology

[0002] With the booming development of integrated substation construction in recent years, the demand for prefabricated substations has continued to rise. The market has put forward more stringent standards for the operating environment of the prefabricated power equipment modules used in prefabricated substations, such as being able to adapt to harsh environments such as the Gobi Desert or similar deserts.

[0003] In existing technologies, ventilation and filtration systems play a central role in prefabricated power equipment cabins, aiming to maintain good air quality within the cabin. However, when used in extreme environments such as the Gobi Desert or similar arid regions, these systems may be obstructed by dust accumulation, thus affecting effective ventilation within the cabin. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a ventilation and filtration device for prefabricated power equipment cabins that allows workers to easily and quickly clean the filters and prevents excessive sand accumulation in the filters from affecting cabin ventilation.

[0005] This utility model is achieved through the following technical solution: a ventilation and filtration device for a prefabricated power equipment cabin is provided, including a ventilation device assembly installed on the outer wall of the prefabricated cabin wall panel. A filter located inside the prefabricated cabin is connected to the air outlet of the ventilation device assembly. A horizontal bar is provided on the top of the filter, and vertical bars that fit against the left and right side walls of the filter are respectively fixed to the left and right ends of the horizontal bar. A connecting rod that is detachably fixed to the bottom of the two vertical bars is provided at the bottom of the filter. The inner side walls of the horizontal bar and the vertical bars are fixedly connected to the ventilation device assembly.

[0006] In use, this utility model features a ventilation assembly installed on the outer wall of a precast cabin wall panel. A filter located inside the precast cabin is connected to the air outlet of the ventilation assembly. A horizontal bar is installed at the top of the filter, with vertical bars fixed to the left and right ends of the horizontal bar, respectively, and attached to the left and right side walls of the filter. A connecting rod is detachably fixed to the two vertical bars at the bottom of the filter. The inner walls of both the horizontal and vertical bars are fixedly connected to the ventilation assembly. When in use, the ventilation assembly installed on the outer wall of the precast cabin wall panel needs to be turned on, allowing outside air to be delivered into the precast cabin through the filter, thus ventilating the cabin. After a period of use, if too much sand accumulates on the filter and affects ventilation, the connecting rod can be removed from the two vertical bars, the filter taken out between the two vertical bars for cleaning, and then the filter placed back between the two vertical bars. The connecting rod is then reinstalled on the two vertical bars. This allows workers to easily and quickly clean the filter, preventing excessive sand accumulation in the filter from affecting ventilation.

[0007] Preferably, the rear sidewalls of the horizontal bars, vertical bars, and connecting rods are sealed against the inner sidewalls of the prefabricated cabin wall panel, and the horizontal bars and vertical bars are fixedly connected to the ventilation device assembly via the prefabricated cabin wall panel. By sealing the rear sidewalls of the horizontal bars, vertical bars, and connecting rods against the inner sidewalls of the prefabricated cabin wall panel, and by fixing the horizontal bars and vertical bars to the ventilation device assembly via the prefabricated cabin wall panel, the sealing effect of the device during use can be improved, preventing unfiltered air from entering the prefabricated cabin, thereby improving the air quality inside the prefabricated cabin.

[0008] Preferably, a first sealing strip is fixedly connected to both the sidewall of the crossbar facing the filter and the sidewall of the vertical bar facing the filter, pressing against the filter. A second sealing strip is fixedly connected to the sidewall of the connecting rod facing the filter, also pressing against the filter. By fixing the first sealing strip to both the sidewall of the crossbar and the sidewall of the vertical bar facing the filter, and the second sealing strip to the sidewall of the connecting rod facing the filter, the sealing effect of the device during use can be further improved, preventing air leakage from the filter edge.

[0009] Preferably, a ventilation plate is provided on the front side of the filter, which fits against the front wall of the horizontal bar, vertical bar, and connecting rod. A first threaded rod is provided on the ventilation plate, and the horizontal bar, vertical bar, and connecting rod are fixedly connected to the ventilation plate via the first threaded rod. By providing a ventilation plate on the front side of the filter that fits against the front wall of the horizontal bar, vertical bar, and connecting rod, and by providing a first threaded rod on the ventilation plate, the horizontal bar, vertical bar, and connecting rod are fixedly connected to the ventilation plate. Using the ventilation plate and the first threaded rod not only ensures smooth airflow and improves filtration efficiency, but also facilitates the fixing of the ventilation plate to the horizontal bar, vertical bar, and connecting rod.

[0010] Preferably, the bottom of the connecting rod is provided with a second threaded rod that matches the vertical rod, and the connecting rod and the vertical rod are detachably fixed together by the second threaded rod. By providing a second threaded rod at the bottom of the connecting rod that matches the vertical rod, and by detachably fixing the connecting rod and the vertical rod together by the second threaded rod, the connecting rod and the vertical rod can be quickly disassembled and reassembled, simplifying the filter replacement and maintenance process, thereby improving the efficiency and convenience of the device.

[0011] The beneficial effects of this utility model are as follows: By installing a ventilation device assembly on the outer wall of the precast cabin wall panel, and connecting a filter located inside the precast cabin to the air outlet of the ventilation device assembly, a horizontal bar is installed on the top of the filter, and vertical bars that fit against the left and right side walls of the filter are fixed to the left and right ends of the horizontal bar, respectively. A connecting rod that is detachably fixed to the two vertical bars is installed at the bottom of the filter. The inner side walls of the horizontal bar and the vertical bars are fixedly connected to the ventilation device assembly. When the device is in use, the ventilation device assembly installed on the outer wall of the precast cabin wall panel needs to be turned on so that the ventilation device assembly sends outside air into the precast cabin through the filter, thereby ventilating the precast cabin. After the device has been used for a period of time, if too much sand accumulates on the filter and affects the ventilation inside the cabin, the connecting rod can be removed from the two vertical bars, the filter can be taken out between the two vertical bars for cleaning, and after cleaning, the filter can be put back between the two vertical bars, and the connecting rod can be reinstalled on the two vertical bars. This allows the staff to clean the filter conveniently and quickly, avoiding the problem of too much sand accumulating in the filter affecting the ventilation inside the cabin.

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0020] like Figures 1-5 The present invention discloses a ventilation and filtration device for a prefabricated power equipment cabin, comprising a ventilation assembly 1 installed on the outer wall of the prefabricated cabin wall panel 2. A filter 10 located inside the prefabricated cabin is connected to the air outlet of the ventilation assembly 1. A horizontal bar 8 is provided on the top of the filter 10. Vertical bars 4 that are attached to the left and right sides of the filter 10 are respectively fixed to the left and right sides of the horizontal bar 8. A connecting rod 6 that is detachably fixed to the bottom of the two vertical bars 4 is provided at the bottom of the filter 10. The inner side walls of the horizontal bar 8 and the vertical bars 4 are fixedly connected to the ventilation assembly 1.

[0021] By sealing the rear sidewalls of the horizontal bar 8, vertical bar 4, and connecting rod 6 against the inner sidewall of the prefabricated cabin wall panel 2, and by fixing the horizontal bar 8 and vertical bar 4 to the ventilation device assembly 1 via the prefabricated cabin wall panel 2, the sealing effect of the device during use is improved, preventing unfiltered air from entering the prefabricated cabin and thus improving the air quality inside the prefabricated cabin. Furthermore, by fixing first sealing strips 9 to the sidewalls of the horizontal bar 8 and vertical bar 4 facing the filter 10, and a second sealing strip 12 to the sidewall of the connecting rod 6 facing the filter 10, the sealing effect of the device during use is further improved, preventing air leakage from the edge of the filter 10. A ventilation plate 5, which fits against the front wall of the horizontal bar 8, vertical bar 4, and connecting rod 6, is provided on the front side of the filter 10. A first threaded rod 3 is provided on the ventilation plate 5, which securely connects the horizontal bar 8, vertical bar 4, and connecting rod 6 to the ventilation plate 5. The ventilation plate 5 and the first threaded rod 3 not only ensure smooth airflow and improve filtration efficiency but also facilitate the fixing of the ventilation plate 5 to the horizontal bar 8, vertical bar 4, and connecting rod 6. A second threaded rod 7, which matches the vertical bar 4, is provided at the bottom of the connecting rod 6. The connecting rod 6 and vertical bar 4 are detachably fixed together via the second threaded rod 7. The second threaded rod 7 allows for quick disassembly and reassembly of the connecting rod 6 and vertical bar 4, simplifying the replacement and maintenance process of the filter 10 and thus improving the efficiency and convenience of the device.

[0022] Combined with appendix Figure 1-5The method of using this utility model is as follows: First, the ventilation device assembly 1 located on the outer wall of the precast cabin wall panel 2 needs to be turned on, so that the ventilation device assembly 1 sends outside air into the precast cabin through the filter 10 and the ventilation plate 5, thereby ventilating the precast cabin. After the device has been used for a period of time, the device may affect the ventilation in the cabin due to too much sand accumulation on the filter 10. At this time, by rotating the first threaded rod 3, the first threaded rod 3 is disengaged from the ventilation plate 5, thereby removing the ventilation plate 5 from the horizontal rod 8, the vertical rod 4 and the connecting rod 6. Then, by rotating the first threaded rod 3, the ventilation plate 5 is removed from the horizontal rod 8, the vertical rod 4 and the connecting rod 6. The second threaded rod 7 is used to detach the second threaded rod 7 from the connecting plate, thereby removing the connecting rod 6 from the two vertical rods 4, so that the second sealing strip 12 is no longer pressing on the filter 10. Then, the filter 10 is removed from the first sealing strip 9 for cleaning. After cleaning, the filter 10 is put back into the first sealing strip 9 or a new filter 10 is put back into the first sealing strip 9. Then, the connecting rod 6 is reinstalled on the two vertical rods 4 through the second threaded rod 7, and the ventilation plate 5 is also reinstalled on the horizontal rod 8, the vertical rods 4 and the connecting rod 6 through the first threaded rod 3.
