Description

Technical Field

[0001] This utility model belongs to the field of meter box technology, and in particular relates to an intelligent meter box that supports heat dissipation and dust prevention. Background Technology

[0002] As a key device at the end of the power system, smart meter boxes are widely used in residential communities, commercial buildings, industrial parks and other scenarios to protect electrical components such as meters and transformers from the influence of the external environment. As the functions of smart meters continue to be enriched, the heat generated during their operation is gradually increasing, and the internal space of the meter box is sealed, making heat dissipation increasingly urgent.

[0003] However, in the process of heat dissipation of the meter box, air inlets and outlets are opened on its exterior to allow air circulation and carry away the heat inside the box. However, in traditional air inlets, only a dust filter is installed for dust prevention. Since the air often carries a certain amount of dust, a single dust filter is difficult to effectively filter and intercept the dust in the air. At this time, the dust will enter the box with the air and adhere to the surface of the components, which not only affects the heat dissipation of the components, but also reduces the service life of the components. Therefore, a smart meter box that supports heat dissipation and dust prevention is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a smart meter box that supports heat dissipation and dust prevention. Specifically, by setting up a heat dissipation and dust prevention component, a negative pressure is created inside the box after the active heat dissipation component is activated. Outside air enters through the air inlet duct and first passes through a dust filter to intercept dust and impurities, reducing the possibility of dust entering the box and contaminating electrical components. Simultaneously, a wave-shaped baffle guides and diverts the airflow, creating a turbulent flow field and further trapping dust. Subsequently, the expansion structure of the air guide shroud ensures that the airflow is evenly distributed to all areas of the box, reducing heat dissipation dead zones. This solves the problem that traditional methods of heat dissipation for meter boxes involve opening air inlets and outlets on the outside to allow air circulation and generate heat inside the box. However, traditional air inlets only use a single dust filter for dust prevention. Since air often carries dust, a single dust filter is insufficient to effectively filter and intercept it. Dust then enters the box with the air and adheres to the surface of the components, affecting heat dissipation and reducing component lifespan.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a smart meter box that supports heat dissipation and dust prevention. It includes a box body, a rainproof roof fixedly connected to the top of the box body, a door hinged to the front of the box body, and a protective mechanism mounted on the box body. The protective mechanism includes a heat dissipation and dust prevention component mounted on the box body, and a disassembly and assembly component mounted on the heat dissipation and dust prevention component. The heat dissipation and dust prevention component includes a mounting plate fixed to the bottom of the box body. Two air inlet pipes are fixedly connected to the bottom of the heat dissipation and dust prevention component. The components connected to the two air inlet pipes are identical and symmetrically arranged. Several wave-shaped baffles are inserted inside the air inlet pipe on the right side. A dustproof net is fixedly connected to the right side of the wave spoiler. A support plate is fixedly connected to the outer ring of the dustproof net. The left side of the support plate contacts the right side of the air inlet pipe. A support frame is fixedly connected to the bottom of the air inlet pipe. A dust collection box is inserted into the support frame. An active heat dissipation component is installed on the top of the box. The dust collection box is correspondingly set at the bottom of several dustproof nets. The surfaces of several dustproof nets are all smooth. A sealing ring is set at the connection between the support plate and the air inlet pipe. An air guide hood is fixedly connected to the bottom of the inner wall of the box. A protective grille is fixedly connected to the inner side of the air guide hood. The air inlet at the bottom of the air guide hood is correspondingly set to the air outlet at the top of the mounting plate. The air guide hood gradually expands from bottom to top.

[0007] Furthermore, there are two sets of disassembly and assembly components. The two sets of disassembly and assembly components contain the same parts. The disassembly and assembly component located on the right side includes two side ears. The two side ears are fixed to the front and back of the support plate, respectively. Each of the two side ears is fixedly connected to a second locking block. Both second locking blocks are barbed. The side of the second locking block near the side ear is set with an angled surface.

[0008] Furthermore, the front and back of the air inlet pipe are fixedly connected to a limiting frame, and each of the two limiting frames is provided with a locking block 1. The left side of each locking block 1 contacts the inclined surface of locking block 2, and the contact surfaces of locking block 1 and locking block 2 are set as opposite inclined surfaces.

[0009] Furthermore, a pull rod is fixedly connected to the top of each of the two engaging blocks. The pull rod is n-shaped and slides through the limiting frame and extends to the top. The outer surface of the limiting frame has anti-slip texture. A sealing ring is provided at the connection between the pull rod and the limiting frame. Two springs are sleeved on the outer surface of the pull rod. The two springs are located inside the limiting frame. The bottom of the two springs is fixedly connected to the top of the engaging block, and the top of the two springs is fixedly connected to the top of the inner wall of the limiting frame.

[0010] Furthermore, the active heat dissipation component includes a protective grille fixed to the top of the inner wall of the box, an installation bracket provided on the inner side of the protective grille, two cooling fans installed on the installation bracket, a dustproof air outlet fixedly connected to the top of the box, the dustproof air outlet being located inside the rainproof top, and an air outlet being opened on the top of the box.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model incorporates a heat dissipation and dust prevention component. Specifically, after the active heat dissipation component is activated, a negative pressure is created inside the housing. Outside air enters through the air inlet pipe and first passes through a dust filter to intercept dust and impurities in the air, reducing the possibility of dust entering the housing and contaminating electrical components. At the same time, a wave-shaped baffle guides and diverts the airflow, creating a turbulent flow field and further trapping dust in the air. Subsequently, in conjunction with the expansion structure of the air guide shroud, the airflow is evenly diffused to all areas of the housing, reducing the occurrence of heat dissipation dead zones. The combination of active heat dissipation and multiple dust prevention measures not only improves heat dissipation efficiency but also enhances the operational stability of the equipment and extends the service life of components.

[0013] 2. This utility model features a disassembly and assembly component. Specifically, when disassembling the dustproof net, pulling the lever upwards moves the locking block one upwards, causing locking block one to disengage from locking block two, allowing the support plate and dustproof net to be quickly removed without additional tools. The operation is convenient and efficient. During installation, align the support plate with the air inlet pipe, and use the lever to make locking block two and locking block one form a stable engagement, completing the installation and fixing. The disassembly and assembly process is quick and labor-saving, greatly improving the efficiency of cleaning and replacing dustproof components and reducing maintenance costs.

[0024] Please see Figures 1-5As shown, this utility model is a smart meter box that supports heat dissipation and dust prevention. It includes a box body 111, a rainproof roof 113 fixedly connected to the top of the box body 111, a door 112 hinged to the front of the box body 111, and a protective mechanism 2 mounted on the box body 111. The protective mechanism 2 includes a heat dissipation and dust prevention component 21 mounted on the box body 111, and a disassembly and assembly component 22 mounted on the heat dissipation and dust prevention component 21. The heat dissipation and dust prevention component 21 includes a mounting plate 210 fixed to the bottom of the box body 111. 1. Two air inlet pipes 214 are fixedly connected to the bottom. The components connected to the two air inlet pipes 214 are identical and symmetrically arranged. Several wave-shaped baffles 2113 are inserted inside the air inlet pipe 214 on the right. A dustproof net 2112 is fixedly connected to the right side of the wave-shaped baffles 2113. A support plate 2111 is fixedly connected to the outer ring of the dustproof net 2112. The left side of the support plate 2111 contacts the right side of the air inlet pipe 214. A support frame 218 is fixedly connected to the bottom of the air inlet pipe 214. A dust collection box 219 is inserted inside the support frame 218. The top of the housing 111 is installed with... It has an active heat dissipation component. The dust collection box 219 is correspondingly set at the bottom of several dust filters 2112, and the surfaces of the dust filters 2112 are all smooth. A sealing ring is set at the connection between the support plate 2111 and the air inlet pipe 214. An air guide hood 212 is fixedly connected to the bottom of the inner wall of the box 111. A protective grille 213 is fixedly connected to the inner side of the air guide hood 212. The air inlet at the bottom of the air guide hood 212 is correspondingly set to the air outlet at the top of the mounting plate 210. The air guide hood 212 is gradually expanded from bottom to top. After the active heat dissipation component is activated, a negative pressure is formed inside the box 111, and the outside air... Air enters through the air inlet duct 214 and first passes through the dust filter 2112 to intercept dust and impurities in the air, reducing the possibility of dust entering the enclosure 111 and contaminating electrical components. At the same time, the wave baffle 2113 guides and diverts the airflow, creating a turbulent flow field and further trapping dust in the air. Subsequently, in conjunction with the expansion structure of the air guide shroud 212, the airflow is evenly diffused to all areas of the enclosure 111, reducing the occurrence of heat dissipation dead zones. The combination of active heat dissipation and multiple dust prevention measures not only improves heat dissipation efficiency but also enhances the stability of equipment operation and extends the service life of components.

[0025] There are two sets of disassembly and assembly components 22. Both sets of disassembly and assembly components 22 contain the same parts. The disassembly and assembly component 22 on the right side includes two side ears 225, which are fixed to the front and back of the support plate 2111, respectively. Each side ear 225 has a locking block 226 fixedly connected to its left side. Both locking blocks 226 are barbed, and the side of the locking block 226 near the side ear 225 is beveled. The air inlet pipe 214 is fixed to both the front and back. A limiting frame 221 is connected, and each limiting frame 221 has a locking block 223 inside. The left side of each locking block 223 contacts the inclined surface of a locking block 226. The contact surfaces of locking blocks 223 and locking blocks 226 are set as opposite inclined surfaces. A pull rod 222 is fixedly connected to the top of each locking block 223. The pull rod 222 is n-shaped and slides through the limiting frame 221 and extends to the top. The outer surface of the limiting frame 221 is... The surface is provided with anti-slip texture. A sealing ring is provided at the connection between the pull rod 222 and the limiting frame 221. Two springs 224 are sleeved on the outer surface of the pull rod 222. The two springs 224 are located inside the limiting frame 221. The bottom of the two springs 224 are fixedly connected to the top of the locking block 1 223. The top of the two springs 224 are fixedly connected to the top of the inner wall of the limiting frame 221. When removing the dustproof net 2112, pull the pull rod 222 upward to move the locking block 1 223 upward, so that the locking block 1 223 and the locking block 2 226 are disengaged. The support plate 2111 and the dustproof net 2112 can be quickly removed without additional tools. The operation is convenient and efficient. During installation, align the support plate 2111 with the air inlet pipe 214. Use the pull rod 222 to make the locking block 2 226 and the locking block 1 223 form a stable engagement to complete the installation and fixation. The disassembly and assembly process is quick and labor-saving, which greatly improves the cleaning and replacement efficiency of dustproof components and reduces maintenance costs.

[0026] The active heat dissipation component includes a protective grille cover 215 fixed to the top of the inner wall of the housing 111. A mounting bracket 216 is provided on the inner side of the protective grille cover 215. Two cooling fans 217 are installed on the mounting bracket 216. A dustproof air outlet 211 is fixedly connected to the top of the housing 111. The dustproof air outlet 211 is located inside the rainproof top 113. An air outlet is opened on the top of the housing 111.

[0027] One specific application of this embodiment is: when in use, the electrical components inside the smart meter box generate heat, which activates the two cooling fans 217 on the mounting bracket 216. The cooling fans 217 create a negative pressure environment inside the box 111, and outside air is drawn in through the air inlet pipe 214.

[0028] After air enters the air inlet duct 214, it first passes through the dustproof net 2112. The dustproof net 2112 intercepts dust, particulate matter and other impurities in the air, preventing them from entering the housing 111 and adhering to the surface of electrical components. Then the airflow passes through several wave baffles 2113. The wave baffles 2113 change the direction of the airflow, making the airflow form a turbulent flow field. At the same time, the wave baffles 2113 will trap dust in the air. Then the air enters the air guide hood 212 through the mounting plate 210. The air guide hood 212 has a structure that gradually expands from bottom to top, which guides the airflow evenly to various areas inside the housing 111 to achieve comprehensive heat dissipation. The protective grille 213 can reduce the situation of foreign objects entering the air guide hood 212.

[0029] After the hot air exchanged heat with the electrical components inside the enclosure 111, it was drawn out by the cooling fan 217 and discharged to the outside of the enclosure through the dustproof air outlet 211. The rainproof roof 113 can effectively reduce the intrusion of rainwater from the dustproof air outlet 211. The dust intercepted by the wave baffle 2113 falls into the dust collection box 219 inside the support frame 218 under the action of gravity, which is convenient for regular cleaning.

[0030] When the dustproof net 2112 needs to be cleaned or replaced, the worker holds the pull rod 222 on the limit frame 221 and pulls the pull rod 222 upward. The pull rod 222 drives the two locking blocks 1 223 to move upward in sync. The spring 224 is compressed, and the locking blocks 1 223 and the locking blocks 226 are disengaged. At this time, the support plate 2111 can be pulled outward directly to remove the support plate 2111, the dustproof net 2112 and the wave deflector 2113 together.

[0031] After cleaning, proceed with the installation. Align the support plate 2111 with the opening of the air inlet pipe 214, and push the support plate 2111 towards the air inlet pipe 214. Simultaneously, pull the lever 222 to move the locking block 223 upwards. During the movement of the locking block 223, it will compress the spring 224. Then, insert the locking block 226 into the limiting frame 221, and release the lever 222. At this point, the spring 224 will generate a certain rebound force and drive the locking block 223 to reset. During the reset process of the locking block 223, its inclined surface will interlock with the locking block 226. When the two locking blocks 226 are in contact with each other, they will move laterally toward the center of the housing 111 under the pressure of the locking blocks 223. During the movement of the locking blocks 226, the side ears 225 will simultaneously drive the support plate 2111 to move. At the same time, since the locking blocks 226 have a barbed design, the possibility of the locking blocks 226 falling off is reduced. The locking blocks 226 complete the installation and fixation of the dustproof net 2112 under the pressure of the locking blocks 223. The sealing ring at the connection between the support plate 2111 and the air inlet pipe 214 ensures the sealing effect and reduces airflow leakage and dust infiltration.

[0032] It should be noted that the cooling fan 217 in this application can be controlled by using a program set in the control panel, and by inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.
