Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0037] like Figures 1-7 As shown, this utility model embodiment provides a secondary water supply control cabinet, including a cabinet body 1. The cabinet body 1 has a mounting cavity 1001. A power supply and a control device are provided in the mounting cavity 1001. The control device is electrically connected to the power supply and is used to supply power to the control device. The control device is an existing device and will not be described in detail. The power supply is installed at the bottom of the mounting cavity 1001 and the control device is located above the power supply.
[0038] Specifically, a top plate 2 is provided at the top of the cabinet 1 to enclose the mounting cavity 1001. A fan 3 is embedded in the top plate 2. Specifically, the top plate 2 has holes for the fan 3, and the fan 3 is installed in the holes by bolts. A top cover 4 is provided above the top plate 2, which covers the fan 3 and forms an air outlet cavity 5 with the top plate 2. The fan 3 connects the mounting cavity 1001 and the air outlet cavity 5, and can transport the air from the mounting cavity 1001 to the air outlet cavity 5. Furthermore, the lower part of the cabinet 1... Each side wall is provided with an air inlet 6 communicating with the mounting cavity 1001. In this embodiment, the cabinet 1 is a cuboid, that is, each of the four side walls at the bottom of the cabinet 1 is provided with an air inlet 6, and the top plate 2 is provided with an air outlet 7 communicating with the air outlet cavity 5. When the user starts the fan 3, the low-temperature air enters the mounting cavity 1001 from the air inlet 6 at the bottom of the cabinet 1 under the action of the fan 3. The air rises in the mounting cavity 1001 and passes through the power supply and control equipment in sequence, carrying away the heat dissipated by the power supply and control equipment. The heat is delivered to the air outlet 5 and then discharged through the air outlet 7 at the air outlet 5, thus stably transporting the heat inside the cabinet 1 to the outside of the cabinet 1, balancing the temperature inside and outside the cabinet 1, preventing excessive temperature difference between the inside and outside of the cabinet 1, reducing the generation of condensate, and thus preventing water from entering the mounting cavity 1001 and damaging the control equipment inside. Moreover, the air outlet 7 can be set downwards to prevent external condensate from dripping directly into the mounting cavity 1001 through the air outlet 7, further improving the waterproof performance. The control equipment of the secondary water supply generates a lot of heat and requires a large amount of heat dissipation. The air inlets 6 are set around the lower part of the cabinet 1 to increase the air intake and dissipate heat from all sides of the control equipment. This can evenly remove heat from all areas of the mounting cavity 1001, avoiding uneven heat dissipation and greatly reducing the possibility of excessive temperature difference between the inside and outside of the cabinet 1 due to excessive temperature in a certain area inside the cabinet 1, resulting in condensate on the outside of the cabinet 1, and improving heat dissipation efficiency.
[0039] Specifically, the top plate 2 includes a top cover plate 201 and a first ventilation plate 202. The top cover plate 201 is connected to the top of the cabinet 1 and serves as the cover plate of the cabinet 1 to enclose the mounting cavity 1001. Three ends of the top cover 4 are bolted to the top cover plate 201, and the last end protrudes from the outside of the cabinet 1 and has a certain gap with the top cover plate 201. The first ventilation plate 202 is located in the gap. Specifically, one end of the first ventilation plate 202 is detachably connected to the top cover plate 201, specifically in this embodiment by bolts. The other end of the first ventilation plate 202 abuts against the side wall of the top cover 4. The air outlet 7 is located on the ventilation plate. The first ventilation plate 202 can be removed for cleaning and replacement. In this embodiment, there are multiple air outlets 7 arranged side by side. Of course, dustproof nets and other dustproof components can be installed at the air outlets 7.
[0040] Specifically, each side wall of the lower part of the cabinet 1 has an installation port, and a second ventilation plate 8 is installed at the installation port. The second ventilation plate 8 is located on the outer side wall of the cabinet 1, with the installation mask inside. The air inlet 6 is located on the second ventilation plate 8. The end of the second ventilation plate 8 is detachably located on the outer side wall of the cabinet 1 at the installation port. Specifically, it can be connected by bolts, which facilitates the disassembly, replacement and cleaning of the second ventilation plate 8 in the future. Moreover, multiple air inlets 6 are evenly arranged on the second ventilation plate 8 to facilitate the uniform entry of low temperature air.
[0041] Specifically, each air inlet 6 is provided with a dust cover 9 that covers the air inlet 6. The dust cover 9 has a downward opening, so that low-temperature air enters the dust cover 9 from bottom to top, and then enters the installation cavity 1001 through the air inlet 6. This avoids the air inlet 6 being directly exposed to the air and can prevent dust and water to a certain extent. In this embodiment, the dust cover 9 can be an arc-shaped cover, which can be installed by bolts or integrally formed with the second ventilation plate 8.
[0042] Specifically, a filter assembly 10 is also provided at the installation port. The filter assembly 10 is located inside the second ventilation plate 8. Under the action of the filter assembly 10, the low-temperature air entering from the air inlet 6 can be further filtered, removing some dust and impurities in the air and preventing them from entering the installation cavity 1001, thus preventing the working environment of the control equipment from being polluted.
[0043] Specifically, in this embodiment, the filter assembly 10 includes filter cotton 101 and filter screen 102. Both filter cotton 101 and filter screen 102 are existing products. The end of the filter screen 102 is detachably disposed on the inner side wall of the cabinet 1 at the installation port. The filter cotton 101 is placed in the installation port and clamped and fixed by the filter screen 102 and the second ventilation plate 8. Of course, the filter assembly 10 can also be set as other existing products, as long as they can filter dust.
[0044] Specifically, the cabinet 1 has a cabinet door 11, with a first bend 12 at the upper end of the cabinet door 11. The top plate 2 has a second bend 13 at the end near the cabinet door 11. The end of the second bend 13 away from the top plate 2 is located below the first bend 12, and the end of the second bend 13 away from the top plate 2 abuts against the cabinet door 11. This allows the first bend 12 and the second bend 13 to work together with the cabinet door 11 to form a waterproof cavity, preventing external condensate and moisture from entering the mounting cavity 1001 through the gap at the top of the cabinet door 11, thus enhancing the waterproof performance of the control cabinet.
[0045] Specifically, in this embodiment, both the first bend 12 and the second bend 13 are L-shaped structures, which are easy to process and manufacture, and the resulting waterproof cavity has a rectangular cross-section. Furthermore, a sealing strip 14 is provided on the inner wall of the cabinet door 11, and the end of the second bend 13 abuts against the sealing strip 14. When the cabinet door 11 is closed, this reduces the impact force between the cabinet door 11 and the end of the second bend 13, and the sealing strip 14 is compressed, resulting in a better sealing effect. Furthermore, an abutment plate 15 is provided at the end of the second bend 13, and the abutment plate 15 is inclined... The angled design allows the abutment plate 15 to contact the sealing strip 14 when the second bend 13 abuts against the cabinet door 11. Specifically, the side wall of the abutment plate 15 near the sealing strip 14 abuts against the sealing strip 14. Compared to the end side wall of the second bend 13 abutting against the sealing strip 14, this increases the contact area with the sealing strip 14, allowing the sealing strip 14 to be utilized more fully. This further enhances the buffering capacity of the sealing strip 14, making the closing process smoother, and also provides a larger sealing surface and a better sealing effect.
[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
