Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prefabricated cabins for electrical equipment, in particular to an automatic dehumidification and anti-corrosion prefabricated cabin for electrical equipment. Background Art
[0002] A prefabricated cabin is a storage device used for the overall installation and transportation of electrical equipment. Users place the assembled electrical equipment in the prefabricated cabin in advance in the factory, and then transport the prefabricated cabin as a whole to the place of use and complete the installation, thereby achieving rapid installation of the electrical equipment.
[0003] A Chinese patent with the announcement number CN216750937U discloses a dehumidifying and anti-corrosion prefabricated cabin for electrical equipment used in offshore booster stations. This cabin not only ventilates the prefabricated cabin through a ventilation and drying device, but also improves the performance and service life of the electrical equipment inside. The cabin door device also improves the moisture and corrosion resistance of the device.
[0004] While the above solution reduces the ingress of salt mist and moisture-laden air into the cabin by designing two hatches, after hatch number one is closed, the salt mist and moisture enter the area between hatches one and two, posing a risk of corrosion to the equipment inside. Furthermore, direct sunlight from the sea can penetrate the cabin directly, resulting in poor thermal insulation. To address this issue, we developed a prefabricated electrical equipment cabin with automatic dehumidification and corrosion resistance. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] like Figure 1-4 As shown, the utility model provides a technical solution: an automatic dehumidification and anti-corrosion prefabricated cabin for electrical equipment, comprising an outer cabin shell 1, a pedestrian passage 17, an air inlet slot 20, a movable component and an air inlet and outlet component.
[0030] An inner shell 2 is fixedly connected to the outer shell 1, and a circulation cavity 3 for air circulation is formed between the outer shell 1 and the inner shell 2. Since there is a circulation cavity 3 between the outer shell 1 and the inner shell 2, the heat irradiated on the outer shell 1 will not be directly transferred to the inner shell 2, thereby having the effect of heat insulation for the inner shell 2. A top plate 11 is fixedly connected to the upper surface of the outer shell 1, and a base 12 is fixedly connected to the bottom surface of the outer shell 1. The top plate 11 can block rainwater dripping on the outer shell 1, and the base 12 supports the outer shell 1.
[0031] The pedestrian passage 17 is fixedly connected to the circulation cavity 3, a first through groove 13 is provided on the outer shell 1, and a second through groove 15 is provided on the inner shell 2. The pedestrian passage 17 is connected to the outer shell 1 and the inner shell 2 through the first through groove 13 and the second through groove 15. A first hatch 14 is installed in the first through groove 13, and a second hatch 16 is installed in the second through groove 15.
[0032] When the maintenance personnel inspect the equipment in the inner cabin shell 2, they need to first open the first hatch 14 to enter the pedestrian passage 17, then close the first hatch 14, and after the high humidity and high salt content air in the pedestrian passage 17 is discharged, enter the inner cabin shell 2 by opening the second hatch 16.
[0033] An air inlet slot 20 is provided on one side of the pedestrian passage 17. A receiving chamber 21 and a limiting chamber 22 are provided in the pedestrian passage 17. A baffle 23 is slidably connected to the receiving chamber 21, and the baffle 23 matches the limiting chamber 22. An air pump 18 is installed on the pedestrian passage 17. The input end of the air pump 18 is fixedly connected to the pedestrian passage 17, and the output end of the air pump 18 passes through the outer cabin shell 1 and is installed with a one-way valve 19.
[0034] The air in the pedestrian passage 17 can be extracted by the air extraction pump 18 and then discharged to the outside of the outer cabin shell 1 through the one-way valve 19, which can prevent high-humidity and high-salt air from directly entering the outer cabin shell 1.
[0035] The movable component is arranged in the circulation cavity 3, and is used to adjust the blocking size of the baffle 23 on the air inlet slot 20. The movable component includes an electric push rod 25 fixedly connected to the outer cabin shell 1, and the telescopic end of the electric push rod 25 is fixedly connected to the connecting plate 24. One end of the connecting plate 24 is fixedly connected to the baffle 23. Rubber pads are installed in the storage cavity 21 and the limit cavity 22, and the rubber pads are against the baffle 23.
[0036] Before the construction workers enter the pedestrian passage 17, the telescopic end of the electric push rod 25 can be moved on the baffle 23 through the connecting plate 24, so that the baffle 23 can completely block the air inlet slot 20. After the construction workers enter the pedestrian passage 17, the electric push rod 25 can be used to drive the baffle 23 to move and open the air inlet slot 20 to avoid the lack of air in the pedestrian passage 17 affecting the construction workers.
[0037] The air inlet and outlet components are arranged on the outer cabin shell 1, and are used to circulate the dehumidified air in the circulation cavity 3. The air inlet and outlet components include an air inlet frame 4 embedded in one side of the outer cabin shell 1, and an air exhaust frame 7 embedded in the other side of the outer cabin shell 1. The air inlet frame 4 is installed with a first steel wire mesh 5 and a filter 6, and the air exhaust frame 7 is installed with an exhaust fan 8 and a second steel wire mesh 9. Both sides of the outer cabin shell 1 are fixedly connected with rain shields 10, and the two rain shields 10 are respectively located above the air inlet frame 4 and above the exhaust frame 7.
[0038] After the exhaust fan 8 is started, suction is generated in the circulation cavity 3, so that the air in the external environment can enter the interior of the outer shell 1 after being filtered through the first steel mesh 5 and the filter 6. The filter 6 can filter moisture and salt in the air. The filter 6 is a HEPA filter.
