Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical cabinets, in particular to a moisture-proof electrical cabinet for building electricity. Background Technique
[0002] In the field of building electricity, the moisture-proof performance of electrical cabinets has always been a key point in technology research and development. In traditional electrical cabinet designs, a leg structure is often used to elevate the cabinet body to reduce direct contact with the wet ground, thereby reducing the potential risk of moisture erosion to the cabinet body. However, such designs still cannot completely solve the damage problem suffered by the bottom of the cabinet body due to long-term exposure to a humid environment.
[0003] Chinese Patent CN220138989U discloses a moisture-proof electrical cabinet. A base with an internal heating plate is provided at the bottom of the cabinet body, and exhaust fans are symmetrically installed above the heating plate. When the heating plate works, it heats the air inside the base, and the exhaust fans discharge the heated air through exhaust holes, aiming to achieve the dehumidification function at the bottom of the electrical cabinet.
[0004] However, when the ground humidity is high and the ambient temperature is moderate, the moisture on the ground is easily evaporated and accumulates at the bottom of the electrical cabinet. At the same time, the electrical cabinet continuously generates and needs to dissipate heat during normal operation, and the heating plate in the base is also continuously working. Since the exhaust fans are located below the heat dissipation fans, the hot air discharged by the exhaust fans will rise. Under the action of the heat dissipation fans, this hot air may be inhaled into the electrical cabinet again, thereby having an adverse impact on the heat dissipation efficiency of the electrical cabinet. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problems raised in the above background technique, and then a moisture-proof electrical cabinet for building electricity is proposed.

Detailed implementation mode
[0022] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the present utility model.
[0023] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.
[0024] Please refer to Figures 1-6 , a moisture-proof electrical cabinet for building electricity provided by an embodiment of the present utility model, the moisture-proof electrical cabinet for building electricity includes:
[0025] An upper box body 1 and a lower box body 2, an insulating pad is provided between the upper box body 1 and the lower box body 2. Such a design can effectively isolate the heat transfer between the upper and lower box bodies 2, and at the same time prevent moisture from entering the upper box body 1. A number of heat absorption holes 121 are provided in the upper box body 1, and these heat absorption holes 121 can effectively absorb and conduct the heat generated inside the electrical cabinet, so as to maintain the working temperature of the electrical cabinet within a suitable range. A number of air extraction holes 21 are provided in the lower box body 2, and the heat absorption holes 121 and the air extraction holes 21 are connected through a connecting member to form an effective heat transfer and discharge system. At least one side of the lower box body 2 is provided with an air extraction fan 22. It can forcibly discharge the hot air and moisture in the lower box body 2, ensuring the drying and heat dissipation effects of the electrical cabinet.
[0026] A plurality of legs 3 are provided at the bottom of the lower box body 2. This can not only stably support the entire electrical cabinet, but also prevent the moisture on the ground from directly eroding the lower box body 2, improving the moisture-proof performance of the electrical cabinet.
[0027] The upper box body 1 includes a bottom plate 11, a back plate 12 is provided on the bottom plate 11, and a number of heat absorption holes 121 are provided on the back plate 12. Such a design enables the heat to be more evenly distributed on the back plate 12 and quickly conducted through the heat absorption holes 121, improving the heat dissipation efficiency.
[0028] Both ends of the backboard 12 are connected to side plates 13, and a top plate 14 is provided on the top of the backboard 12 and the side plates 13, forming a closed space, effectively protecting the internal electrical equipment from the influence of the external environment; a rotating door 15 is rotatably connected to the side plate 13, facilitating the inspection and maintenance of the interior of the electrical cabinet.
[0029] As Figure 2 and Figure 3 shown, the communication member includes a connecting pipe 42. One end of the connecting pipe 42 is connected to an air extraction hole 21, and the other end is connected to an air suction hood 41. The air suction hood 41 is fixedly connected to the backboard 12 such that the air extraction hole 21 communicates with the heat absorption hole 121. The working principle of this design is that the heat generated inside the electrical cabinet is first effectively absorbed by the heat absorption hole 121, and then these heats are guided into the air suction hood 41. Next, the heat is transmitted into the lower box body 2 through the connecting pipe 42 and the air extraction hole 21. During this transmission process, the heat continuously heats the air suction hood 41, the connecting pipe 42, and the lower box body 2, which not only helps with dehumidification but also actually consumes part of the heat. Finally, these processed air, although still carrying a certain amount of heat, has been discharged to the outside through the air extraction fan 22. It should be noted that compared with the hot air directly heated and discharged in the prior art, the heat in the air discharged in this way has been greatly reduced. Such a design not only improves the heat dissipation efficiency but also effectively controls the temperature of the discharged air, thus being more environmentally friendly and energy-saving.
[0030] As Figure 4 shown, the communication member includes a connecting pipe 42. The connecting pipe 42 is connected to a main air extraction pipe 43, and a number of heat absorption pipes 44 cooperating with the heat absorption hole 121 are provided on the main air extraction pipe 43. In this design, the heat generated inside the electrical cabinet is first efficiently extracted through the heat absorption hole 121 and immediately introduced into the corresponding heat absorption pipes 44. Subsequently, these heats will enter the main air extraction pipe 43 along the heat absorption pipes 44, and then be transmitted into the lower box body 2 through the connecting pipe 42 and the air extraction hole 21. In the lower box body 2, the heat plays a dual role: on the one hand, it heats the box body, helping to remove the internal moisture; on the other hand, it is gradually consumed during this process. Finally, the air after this series of treatments has its moisture effectively removed, and the remaining heat is also smoothly discharged to the outside through the air extraction fan 22.
[0031] As Figure 5 and Figure 6As shown, a plastic plate 23 is slidably fitted to the bottom of the lower box body 2. Specifically, the lower box body 2 includes a lower plate 24, on which a first vertical plate 241 and a second vertical plate 242 are formed. A guiding groove 243 is formed between the first vertical plate 241 and the second vertical plate 242. The plastic plate 23 includes a lower sealing plate 231, which is connected to an upper connecting plate 232. The upper connecting plate 232 is connected to an upper horizontal plate 233. A guiding sealing strip 234 that mates with the guiding groove 243 is formed at the bottom of the upper horizontal plate 233. Such a design not only enhances the sealing performance of the box body to prevent moisture intrusion, but also enables convenient disassembly and installation, facilitating the cleaning and maintenance of the interior of the lower box body 2.
[0032] A cylindrical notch is formed in the middle of the guiding groove 243, and a mating cylindrical strip that mates with the cylindrical notch is formed in the middle of the guiding sealing strip 234. This structure further improves the precision and stability of the sliding fit, and also enhances the sealing effect, providing a strong guarantee for the long-term stable operation of the electrical cabinet.
[0033] Working mode: Install the moisture-proof electrical cabinet in a proper position, ensure that the heat insulation pad between the upper box body 1 and the lower box body 2 is properly installed, and at the same time, ensure the sealing performance of all box body parts to prevent moisture intrusion. Connect power supplies to the exhaust fan 22 and other electrical equipment that may be required to ensure their normal operation. Ensure that the connecting components (such as connecting pipe 42, air suction hood 41, main exhaust duct 43, and heat absorption pipe 44, etc.) between the heat absorption holes 121 and the exhaust holes 21 are correctly installed and unobstructed, so as to effectively extract the heat from the heat absorption holes 121 and transfer it to the lower box body 2. Turn on the exhaust fan 22 to start extracting the heat and moisture inside the electrical cabinet. The heat will be transferred to the lower box body 2, and the moisture will be further removed by heating the lower box body 2. Regularly check the working status of the electrical cabinet, including parameters such as temperature and humidity, and adjust the operating speed of the exhaust fan 22 or other relevant settings according to the actual situation to ensure that the environment inside the electrical cabinet remains in the best state.
[0034] If condensation or dampness is found inside the electrical cabinet, immediately check whether components such as the heat insulation pad and the sealing strip are in good condition, and promptly replace the damaged components. When used in a humid season or a humid environment, increase the inspection frequency, and consider increasing the operating time or speed of the exhaust fan 22 to ensure the dryness inside the electrical cabinet. If maintenance or repair of the electrical cabinet is required, first turn off the power supply and ensure safety before proceeding with the operation.
[0035] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
