[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] like Figures 1 to 3 As shown, an electrical automation PLC control cabinet according to one embodiment of the present invention includes a cabinet body 1, in which electrical components are installed. A cabinet door 11 is rotatably connected to the cabinet body 1. Because the cabinet body 1 is mounted on a tower crane at high altitude and unobstructed, the cabinet body 1 is well sealed to prevent rainwater from entering. However, exposure to sunlight in the summer can cause the cabinet body 1 to heat up, affecting the normal operation of the electrical components within.

[0036] In order to cool down the electrical components of the cabinet 1, Figures 2 to 3 As shown, a first fan 111 is installed on the cabinet door 11, which can extract the air in the cabinet 1 and preliminarily cool the electrical components in the cabinet 1. At the same time, a partition plate 12 is integrally formed in the cabinet 1, and an electrical installation space 13 is formed between the front panel of the partition plate 12 and the cabinet door 11, and the electrical components are installed in the electrical installation space 13. A cooling space 14 is formed between the rear panel of the partition plate 12 and the back panel of the cabinet 1. A second fan 121 is installed on the partition plate 12, and when the second fan 121 is working, it can blow the air in the cooling space 14 into the electrical installation space 13. A cooling component is also installed on the cabinet 1, a part of the cooling component passes through the upper panel of the cabinet 1, and a part is inside the cooling space 14, and an air inlet 141 matching the cooling space 14 is provided on the lower panel of the cabinet 1.

[0037] Specifically, the cooling assembly includes a water reservoir 2, the lower panel of which is threaded with bolts. The water reservoir 2 is then threadedly connected to the upper panel of the cabinet 1. A connecting pipe 21 is installed within the water reservoir 2. The connecting pipe 21 passes through the lower panel of the water reservoir 2 and the upper panel of the cabinet 1 and extends into the cooling space 14. Fins 212 are integrally formed on the connecting pipe 21.

[0038] Specifically, when the electrical automation PLC control cabinet is operating, it generates a significant amount of heat. This, combined with sunlight exposure, leads to a high temperature within the electrical installation space 13. Water flows through the connecting pipe 21, exchanging heat with the fins 212 to lower the temperature within the cooling space 14. The water is then blown into the electrical installation space 13 via the second fan 121, cooling the air within the space. The rotation of the second fan 121 simultaneously activates the first fan 111, enhancing air circulation within the space 13 and further reducing the air temperature within the space. This maintains a relatively low temperature within the space, protecting the electrical components within.

[0039] Furthermore, after the air in cooling space 14 is blown into electrical installation space 13, air from outside cabinet 1 enters cooling space 14 through air inlet 141 under the influence of atmospheric pressure. Because air inlet 141 is located on the lower panel of cabinet 1, the newly entered air in cooling space 14 must undergo heat exchange with multiple second fans 121 before being blown into electrical installation space 13. During this process, the heat exchange with second fans 121 significantly reduces the temperature of the newly entered air in cooling space 14.

[0040] At the same time, because the air outside cabinet 1 is relatively hot, when this hot air enters cooling space 14, it encounters the cooler air inside cooling space 14, liquefying and forming water droplets. These water droplets fall to the ground through air inlet 141. Furthermore, the humidity of the liquefied air is reduced, and when it is blown into electrical installation space 13 by second fan 121, it keeps the interior of electrical installation space 13 dry, providing better protection for the electrical components within.

[0041] Furthermore, the four sidewalls of the water storage box 2 are honeycomb-shaped, which can reduce the heat transfer when sunlight hits the water storage box 2. In addition, the water storage box 2 is white in color, which can reflect part of the sunlight and effectively reduce the water temperature in the water storage box 2.

[0042] It is worth noting that the water in the water storage box 2 will gradually decrease after evaporation after long-term use. The water can be hoisted up by a tower crane, and the cover of the water storage box 2 can be opened by holding the vent hole on the upper cover of the water storage box 2 to replenish the water in the water storage box 2.

[0043] At the same time, if it rains, rainwater flows into the water storage box 2 through the vent holes on the cover plate of the water storage box 2 to replenish the water in the water storage box 2.

[0044] like Figures 5 to 7 As shown, the connecting pipe 21 is U-shaped. This U-shape increases the number of external threads 211, enhancing heat exchange. One end of the connecting pipe 21, located within the water reservoir 2, protrudes from the lower panel of the water reservoir 2. Specifically, because the tower crane is located in a dusty construction environment, a small amount of dust will fall into the water reservoir 2 and accumulate on the bottom wall of the water reservoir 2. The upper end of the connecting pipe 21 protruding from the lower panel of the water reservoir 2 effectively prevents dust from entering the connecting pipe 21.

[0045] Furthermore, the connecting tube 21 is provided with an external thread 211, which is threadably connected to a limit ring 22. A rubber pad 221 is bonded to the lower panel of the limit ring 22, and a rocker 222 is integrally formed on the upper panel of the limit ring 22. Specifically, the connecting tube 21 is fixed to the lower panel of the water storage box 2 via the limit ring 22. The rubber pad 221 on the limit ring 22 provides a seal between the water storage box 2 and the connecting tube 21, preventing water from leaking from the connection between the water storage box 2 and the connecting tube 21.

[0046] Specifically, after the project is completed, the tower crane will be dismantled, and the electrical automation PLC control cabinet will also be removed from the tower crane and transported to the next construction site. At this time, the rocker 222 can be shaken to separate the limit ring 22 from the connecting pipe 21, and then the connecting pipe 21 can be removed from the air inlet 141, making it convenient to flush the inner wall of the connecting pipe 21 with a high-pressure water gun to wash away the scale on the inner wall of the connecting pipe 21 and prevent clogging of the connecting pipe 21.

[0047] like Figure 2 、 Figure 3 and Figure 8 As shown, a filter assembly matching the air inlet 141 is welded to the lower panel of the cabinet 1. This filter assembly is used to filter dust from the air. The filter assembly includes a protective frame 3, which is welded to the lower panel of the cabinet 1. A first protective plate 32 is mounted on the protective frame 3, and a filter screen 321 is provided on the first protective plate 32. A chute 31 matching the first protective plate 32 is defined in the protective frame 3. The chute 31 extends through a side wall of the protective frame 3, and the first protective plate 32 is slidably connected within the chute 31.

[0048] Specifically, the filter 321 can block dust in the air and ensure the cleanliness of the air entering the cooling space 14. When there is a lot of dust on the filter 321, the first protective plate 32 can be pulled to slide the first protective plate 32 out of the filter 321 to clean the dust on the filter 321.

[0049] It is worth noting that the water droplets generated by the liquefaction of the air in the cooling space 14 can also wash away some of the dust on the filter 321 , which can effectively reduce the frequency of cleaning the filter 321 .

[0050] like Figure 1 、 Figure 3 、 Figure 4 and Figure 9 As shown, a protective assembly for shielding the first fan 111 is installed on the cabinet door 11. The protective assembly includes a fixing plate 4, which is welded to the front panel of the cabinet door 11. The fixing plate 4 is provided with a through slot 41, and a second protective plate 42 is slidably connected to the through slot 41. The second protective plate 42 is provided with a first baffle 421 and a second baffle 422, and a magnet block 422 is fixedly connected to the second baffle 422.

[0051] Specifically, when the electrical automation PLC control cabinet is started, the first baffle 421 is pulled upward, and the magnet block 4221 on the second baffle 422 is magnetically attracted to the lower panel of the fixed plate 4. The first fan 111 rotates and exhausts the air in the electrical installation space 13. In rainy weather, the first baffle 421 is pressed downward, and the first baffle 421 falls on the upper panel of the fixed plate 4. The second protective plate 42 shields the first fan 111, preventing rainwater from entering the electrical installation space 13 through the first fan 111. This protects the electrical components in the electrical installation space 13 and also protects the first fan 111 from damage.

[0052] During operation, the second fan 121 rotates, blowing air from the cooling space 14 into the electrical installation space 13. Since the air in the cooling space 14 passes through the heat exchanger of the second fan 121, its temperature is relatively low, effectively reducing the temperature within the electrical installation space 13. Simultaneously, the first fan 111 rotates, enhancing air circulation within the electrical installation space 13 and achieving better heat dissipation for the electrical components within the electrical installation space 13.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
