Description

Technical Field

[0001] This application relates to the field of metering box technology, and in particular to an electricity metering box. Background Technology

[0002] Outdoor electricity metering boxes are exposed to the natural environment for extended periods, facing numerous challenges. Dust intrusion is a significant factor. Once inside the metering box, dust adheres to the surfaces of electrical components, affecting their heat dissipation, accelerating aging, and reducing insulation performance. This increases the risk of equipment failure and impacts the accuracy and stability of electricity metering.

[0003] Currently, to address this issue, some metering boxes achieve dust prevention by installing dustproof plates with screws at the air inlet or outlet.

[0004] However, installing the dust cover with screws makes it inconvenient to disassemble and clean it. Summary of the Invention

[0005] This application provides an electricity metering box to solve the problem that existing dustproof panels are installed with screws, which makes it inconvenient to disassemble and clean the dustproof panels.

[0006] This application provides an electricity metering box, including:

[0007] The enclosure has an air inlet and an air outlet; the enclosure also has a first fixing part located outside the air inlet.

[0008] A dustproof plate includes a filter element and a mounting element; the filter element covers the air inlet, the mounting element is arranged around the outside of the filter element, the dustproof plate is provided with a second fixing part, the second fixing part is inserted into and engaged with a first fixing part; a first suction element is provided at the end of the first fixing part, a second suction element is provided at the end of the second fixing part, at least one of the first suction element and the second suction element is a magnetic element, and the first suction element and the second suction element are magnetically engaged.

[0009] The fixing structure includes a first fixing member and a second fixing member that cooperate with each other. The first fixing member is disposed on the housing, and the second fixing member is disposed on the mounting member. The first fixing member and the second fixing member are detachably connected.

[0010] By adopting the above technical solution, the electricity metering box includes a box body, a dustproof plate, and a fixing structure. The box body includes a first fixing part, and the dustproof plate includes a second fixing part. The second fixing part and the first fixing part are inserted and matched. The fixing structure includes a first fixing member and a second fixing member that cooperate with each other. The first fixing member is disposed on the box body, and the second fixing member is disposed on the mounting part. The first fixing member and the second fixing member are detachably connected, thereby fixing the dustproof plate on the box body.

[0011] When the dust cover needs to be installed, simply insert the second fixing part of the dust cover into the first fixing part of the housing, and then secure it using the first and second fixing parts of the fixing structure. This allows for quick installation of the dust cover. Because the fixing structure uses a detachable connection method, removing and cleaning the dust cover is also more convenient.

[0012] In addition, the dustproof panel is secured to the enclosure through a combination of plug-in fitting and a fixed structure, which effectively prevents the dustproof panel from warping or deforming after long-term use, ensuring the airtightness between the dustproof panel and the enclosure and preventing dust and lint from entering the enclosure from the gaps.

[0013] It is easy to understand that, compared with the method of fixing the dustproof plate with screws or clips in related technologies, the power metering box of this application adopts a dual fixing method of plug-in and fixed structure. This not only enables the quick installation and removal of the dustproof plate, but also effectively prevents the dustproof plate from warping or deforming after long-term use, ensuring the sealing between the dustproof plate and the box body, thereby improving the dustproof effect and extending the service life of the power metering box.

[0021] When the second fastener is connected to the first fastener, at least a portion of the second fastener extends out of the dustproof plate, and the portion of the second fastener extending out of the dustproof plate engages with the first fastener.

[0022] In some possible implementations, the sliding seat is provided with a sliding groove having an opening toward the outside of the dustproof plate;

[0023] When the second fastener is connected to the first fastener, at least a portion of the second fastener extends out of the opening;

[0024] In some possible implementations, the sliding seat is provided with a push groove, which communicates with the sliding groove, and the extension direction of the push groove is the same as the extension direction of the sliding groove.

[0025] The second fixing member is provided with a pushing part, which is slidably disposed in the pushing groove along the extension direction of the pushing groove, and at least a portion of the pushing part extends out of the sliding seat away from the surface of the housing.

[0026] In some possible implementations, the slide seat is provided with an elastic element located within a sliding groove;

[0027] The first end of the elastic element is connected to the sliding seat, and the second end of the elastic element is connected to the second fixing element. The elastic element is used to apply a force to the second fixing element to extend the opening.

[0028] In some possible implementations, a mounting bracket and an exhaust fan are included;

[0029] The mounting bracket is located inside the housing, near the air outlet.

[0030] The exhaust fan is detachably mounted on the mounting bracket, with the air inlet of the exhaust fan facing the inside of the housing and the air outlet facing the air vent.

[0053] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] As described in the background section, outdoor electricity metering boxes are exposed to the natural environment for a long time, which can lead to dust intrusion. Once dust enters the electricity metering box, it adheres to the surface of electrical components, affecting the heat dissipation performance of the components, accelerating component aging, reducing their insulation performance, thereby increasing the risk of equipment failure and affecting the accuracy and stability of electricity metering.

[0055] To address this issue, some electricity metering boxes install dust covers with screws at the air inlet or vent to prevent dust intrusion. However, while screwing provides strong mechanical fixation, the complex disassembly and assembly process increases maintenance difficulty and time costs, and is not convenient for disassembling and cleaning the dust covers.

[0056] In contrast, the method of securing the dustproof panel to the electricity metering box by setting clips on both sides of the panel is more convenient because the clips are usually made of elastic materials, providing a degree of flexibility and allowing users to easily insert or remove the dustproof panel without tools. However, due to the aging of the clip materials, environmental factors, and frequent disassembly and assembly, the clips may lose their elasticity and fail to effectively maintain a seal.

[0057] Furthermore, dustproof panels are usually made of plastic, metal, or other synthetic materials. When these materials are exposed to the outdoor environment for a long time, they will be affected by factors such as ultraviolet radiation, temperature changes, and humidity, which will cause the materials to age, causing the dustproof panels to warp or deform. At this time, simply setting buckles on both sides of the dustproof panel for fixation cannot prevent dust and airborne lint from entering the interior of the box through the gap between the dustproof panel and the surface of the box.

[0058] To address the aforementioned technical problems, this application provides an electricity metering box, which includes a box body, a dustproof plate, and a fixing structure. The box body includes a first fixing part, and the dustproof plate includes a second fixing part. The second fixing part and the first fixing part are inserted into each other. The fixing structure includes a first fixing member and a second fixing member that cooperate with each other. The first fixing member is disposed on the box body, and the second fixing member is disposed on the mounting member. The first fixing member and the second fixing member are detachably connected, thereby fixing the dustproof plate to the box body.

[0059] When the dust cover needs to be installed, simply insert the second fixing part of the dust cover into the first fixing part of the housing, and then secure it using the first and second fixing parts of the fixing structure. This allows for quick installation of the dust cover. Because the fixing structure uses a detachable connection method, removing and cleaning the dust cover is also more convenient.

[0060] In addition, the dustproof panel is secured to the enclosure through a combination of plug-in fitting and a fixed structure, which effectively prevents the dustproof panel from warping or deforming after long-term use, ensuring the airtightness between the dustproof panel and the enclosure and preventing dust and lint from entering the enclosure from the gaps.

[0061] It is easy to understand that, compared with the method of fixing the dustproof plate with screws or clips in related technologies, the power metering box of this application adopts a dual fixing method of plug-in and fixed structure. This not only enables the quick installation and removal of the dustproof plate, but also effectively prevents the dustproof plate from warping or deforming after long-term use, ensuring the sealing between the dustproof plate and the box body, thereby improving the dustproof effect and extending the service life of the power metering box.

[0068] Reference Figures 1-3 The electricity metering box provided in this application embodiment includes a box body 100, a dustproof plate 200, and a fixing structure 300. The dustproof plate 200 and the box body 100 are fixed together by the fixing structure 300.

[0069] The enclosure 100 may be equipped with an air inlet 110 and an air outlet 120. The air inlet 110 is used to introduce fresh air from the outside and remove the heat generated by the various electronic components inside the power metering box during operation, preventing the equipment from overheating. The air outlet 120 is used to exhaust the hot air inside the enclosure 100, keeping the internal temperature of the equipment within a reasonable range and avoiding excessive temperature from affecting the working efficiency and lifespan of the electronic components. The air inlet 110 and the air outlet 120 work together to form an effective airflow path, promote the circulation of internal air, and improve the heat dissipation effect.

[0070] The dustproof plate 200 can be installed at the air inlet 110 of the enclosure 100, or at the air outlet 120 of the enclosure 100, or at both the air inlet 110 and the air outlet 120, to prevent dust from entering the interior of the enclosure 100.

[0071] For example, an electricity metering box may be provided with a box door 600 and an electricity metering device 700. The box door 600 is hinged to the surface of the box body 100, and the electricity metering device 700 is located inside the box body 100. The surface of the box door 600 may also be embedded with an observation window 610, through which the working status of the electricity metering device 700 inside the box body 100 and the information displayed on the display screen of the electricity metering device 700 can be observed.

[0072] For example, the electricity metering box may be equipped with a canopy 800, which is fixedly connected to the top of the box 100. The canopy 800 can protect the box 100 and prevent rainwater from entering the interior of the box 100, which could cause leakage and damage to the electronic components inside the electricity metering device 700.

[0073] Reference Figures 3-5 In some possible implementations, a first fixing part 111 may be provided on the outer side of the air inlet 110. The outer side of the air inlet 110 may refer to the side of the air inlet 110 away from the housing 100. The first fixing part 111 may be provided on the outer wall of the housing 100 near the outer side of the air inlet 110. The first fixing part 111 may be used to insert and cooperate with the second fixing part 211 on the dustproof plate 200.

[0074] The dustproof plate 200 may include a filter element 210 and a mounting element 220. The filter element 210 may refer to a component with the function of filtering dust, such as a metal mesh, non-woven fabric, activated carbon filter, or multi-layer composite filter material, etc. The mounting element 220 may be arranged around the outside of the filter element 210 for fixing the filter element 210.

[0075] In some possible implementations, a sealing gasket may be fixedly connected to the surface of the dustproof plate 200 near the housing 100. The sealing gasket is located between the dustproof plate 200 and the housing 100, which can improve the sealing performance between the dustproof plate 200 and the housing 100.

[0076] The dustproof plate 200 may also be provided with a second fixing part 211. The second fixing part 211 may be provided on the filter element 210 or on the mounting part 220. It is used to insert and cooperate with the first fixing part 111 on the housing 100 to realize the positioning of the dustproof plate 200 on the outer wall of the housing 100, as well as the quick installation and removal of the dustproof plate 200.

[0077] The fixing structure 300 may include a cooperating first fixing member 310 and a second fixing member 320. The first fixing member 310 may be disposed on the housing 100, and the second fixing member 320 may be disposed on the mounting member 220. The first fixing member 310 and the second fixing member 320 may be detachably connected. When the dustproof plate 200 is installed at the air inlet 110, the first fixing member 310 and the second fixing member 320 may be tightly connected and locked by means of pins, buckles or threads to ensure that the dustproof plate 200 is firmly fixed at the air inlet 110. When the dustproof plate 200 is removed from the air inlet 110, the first fixing member 310 and the second fixing member 320 are separated and unlocked.

[0078] For example, the first fixing part 111 can be configured as a groove facing the outside of the housing 100, and the second fixing part 211 can be configured as a plug-in part. The plug-in part is disposed on the first surface of the mounting member 220 or the first surface of the filter member 210. The extension direction of the plug-in part is perpendicular to the plane of the mounting member 220. The first surface of the mounting member 220 can refer to the side of the mounting member 220 close to the outer wall of the housing 100, and the first surface of the filter member 210 can refer to the side of the filter member 210 close to the outer wall of the housing 100. When it is necessary to fix the dustproof plate 200 to the housing 100, the dustproof plate 200 can be aligned with the air inlet 110, and the plug-in part can be aligned with the groove on the housing 100. The dustproof plate 200 can be gently pressed, and the plug-in part slides into the groove. When it is necessary to remove the dustproof plate 200 from the housing 100, the plug-in part can be pulled out from the groove.

[0079] Alternatively, the first fixing part 111 can be configured as a plug-in part, which is located on the outside of the air inlet 110 and extends perpendicularly to the plane of the air inlet 110. The second fixing part 211 can be configured as a groove, which faces the first surface of the mounting member 220.

[0080] For example, there can be multiple plug-in portions and multiple grooves. The number and position of the plug-in portions can correspond to the number and position of the grooves. At least some of the plug-in portions are located at the first surface edge of the mounting member 220 or the first surface edge of the filter member 210, and at least some of the grooves are located near the edge of the air inlet 110. The position near the edge of the air inlet 110 can be determined according to the size of the dustproof plate 200. Since some plug-in portions are located at the first surface edge of the mounting member 220 or the first surface edge of the filter member 210, and the mounting member 220 is arranged around the outside of the filter member 210, the filter member 210 can cover the air inlet 110. Therefore, the position of the groove corresponding to the plug-in portion located at the edge of the dustproof plate 200 is the position near the edge of the air inlet 110. Fixing the edges makes it easier to achieve a tight fit between the dustproof plate 200 and the housing 100, reducing gaps caused by thermal expansion and contraction of materials or long-term use, helping to prevent external pollutants such as dust and moisture from entering the equipment and improving the sealing effect.

[0081] When the dustproof plate 200 is polygonal in shape, some of the plug-in parts can also be set at the corners of the dustproof plate 200 edge. Correspondingly, some of the grooves can be set at the edge near the air inlet 110 corresponding to the plug-in parts. Since the corners are usually structurally more robust locations, fixing them at the corners with plug-in parts and grooves can distribute the external force more evenly between the dustproof plate 200 and the housing 100, reducing local stress concentration and lowering the risk of deformation.

[0082] For example, the end of the first fixing part may be provided with a first attraction member (not shown in the figure), and the end of the second fixing part may be provided with a second attraction member (not shown in the figure). At least one of the first attraction member and the second attraction member may be provided as a magnetic member, so as to realize the magnetic attraction between the first attraction member and the second attraction member, thereby enabling a more stable connection between the insertion part and the groove.

[0083] For example, the second attractor can be a magnetic element, which can be embedded inside the plug or pasted on the surface of the plug to provide magnetic attraction. The first attractor can be a metal element, which can be embedded in the bottom or side wall of the groove to generate a magnetic attraction with the magnetic element in the second attractor, ensuring that the plug can be stably inserted and fixed in the groove.

[0084] Alternatively, the second attractor can be a metal part, which can be embedded inside the plug or pasted on the surface of the plug. The first attractor can be a magnetic part, which can be embedded in the bottom or side wall of the groove to provide magnetic attraction. The second attractor can generate a magnetic attraction with the magnetic part in the first attractor.

[0085] Alternatively, both the first and second attracting elements can be magnetic, with opposite outward-facing magnetic poles. One can have its S pole facing outward, and the other its N pole facing outward. When the insertion part is inserted into the groove, the first and second attracting elements can be firmly joined together because the N pole and S pole attract each other.

[0086] For example, the first fixing member 310 can be fixedly connected to the housing 100, and the second fixing member 320 can be movably disposed on the second surface of the mounting member 220. The second surface of the mounting member 220 can refer to the side of the mounting member 220 away from the outer wall of the housing 100. When it is necessary to disassemble the fixing structure 300, the second fixing member 320 on the mounting member 220 is moved to release it from the locking of the first fixing member 310 on the housing 100. When the plug-in part is inserted into the groove, the first fixing member 310 and the second fixing member 320 are connected. The plug-in engagement between the plug-in part and the groove can limit the position of the dustproof plate 200 on the plane where the air inlet 110 is located. The connection between the first fixing member 310 and the second fixing member 320 can limit the position of the dustproof plate 200 on a plane perpendicular to the plane where the air inlet 110 is located, thereby achieving double fixation between the dustproof plate 200 and the housing 100 through plug-in engagement and fixing structure 300.

[0087] Alternatively, the first fixing member 310 can be movably mounted on the housing 100, and the second fixing member 320 can be fixedly connected to the second surface of the mounting member 220. When it is necessary to disassemble the fixing structure 300, the first fixing member 310 on the housing 100 can be moved to release it from the second fixing member 320 on the mounting member 220.

[0088] The number of first fixing members 310 and second fixing members 320 can be multiple, and the number and position of the first fixing members 310 and second fixing members 320 can be set accordingly. For example, there can be two first fixing members 310, and correspondingly, there can be two second fixing members 320. The positions of the second fixing members 320 can be symmetrically distributed on both sides of the middle of the mounting member 220. Correspondingly, the positions of the first fixing members 310 can be symmetrically distributed on both sides of the middle of the air outlet 120 of the housing 100. The first fixing members 310 and second fixing members 320 are aligned, which can improve the stability of the connection between the dustproof plate 200 and the housing 100, making the connection between the dustproof plate 200 and the housing 100 more secure.

[0089] The dustproof plate 200 can also be provided with a handle 230. The handle 230 can be fixedly connected to the surface of the dustproof plate 200. There can be multiple handles 230. In this embodiment, there can be two handles 230. The two handles 230 are respectively disposed between two second fixing blocks. By holding the handles 230, the convenience of disassembling and assembling the dustproof plate 200 is further improved.

[0090] For example, the dustproof plate 200 may be provided with a sliding seat 240, and the second fixing member 320 may be movable relative to the sliding seat 240. When it is necessary to connect the second fixing member 320 with the first fixing member 310, the second fixing member 320 may be moved so that part of the second fixing member 320 extends out of the dustproof plate 200 and the part extending out of the dustproof plate 200 is inserted and engaged with the first fixing member 310. By using the second fixing member 320, which is partly on the dustproof plate 200 and partly extends out of the dustproof plate 200 and engages with the first fixing member 310 on the housing 100, the dustproof plate 200 can be fixed on the housing 100.

[0091] The sliding seat 240 may be provided with a sliding groove 241, which may have an opening facing the outside of the dustproof plate 200. The second fixing member 320 can slide in the sliding seat 240 through the sliding groove 241, and when it is necessary to connect the second fixing member 320 with the first fixing member 310, it will partially extend out of the opening of the sliding groove 241.

[0092] The sliding seat 240 may also be provided with a push groove 242, which is connected to the sliding groove 241. The extension direction of the push groove 242 is the same as the extension direction of the sliding groove 241. The second fixing member 320 may be provided with a push part 321, which can be slidably disposed in the push groove 242 along the extension direction of the push groove 242. At least a portion of the push part 321 extends out of the surface of the sliding seat 240 away from the housing 100. Thus, when it is necessary to slide the second fixing member 320, the push part 321 extending out of the surface of the sliding seat 240 can be used to apply the force required for the second fixing member 320 to slide, so that the second fixing member 320 partially extends out of the opening of the sliding groove 241 or retracts into the sliding seat 240.

[0093] Alternatively, at least a portion of the pushing part 321 may extend out of the sliding seat 240 perpendicular to the surface of the housing 100, which may also serve to assist in applying the force required for sliding to the second fixing member 320.

[0094] For example, the sliding seat 240 may be provided with an elastic element 243, which is located within the sliding groove 241. The first end of the elastic element 243 is connected to the sliding seat 240, and the second end is connected to the second fixing member 320. The elastic element 243 can apply a force to the second fixing member 320 to extend its opening. The elastic element 243 can be a spring. The connection between the two ends of the elastic element 243 and the sliding seat 240 and the second fixing member 320 can include welding, bolting, or embedding. When the second fixing member 320 is connected to the first fixing member 310, the elastic element 243 continuously applies a force to the second fixing member 320 to extend its opening, ensuring that the second fixing member 320 is securely fixed to the first fixing member 310, preventing loosening or accidental detachment. When it is necessary to disassemble the second fixing member 320 from the first fixing member 310, the second fixing member 320 can be pushed back into the sliding seat 240 by pressing the pushing part 321 to overcome the force of the elastic element 243.

[0095] Reference Figure 3 and Figure 6 In some possible implementations, the electricity metering box may be equipped with a mounting bracket 400 and an exhaust fan 500. The mounting bracket 400 is used to fix the exhaust fan 500, and the exhaust fan 500 is used to exhaust the heat generated by the electronic components in the electricity metering box during operation from the inside of the equipment, maintain a suitable operating temperature, and thus extend the service life of the electronic components.

[0096] The mounting bracket 400 can be set inside the housing 100, near the air outlet 120, so that the exhaust fan 500 fixed on the mounting bracket 400 can quickly expel heat from the air outlet 120, accelerate heat dissipation, keep the temperature inside the housing 100 within the normal range, improve the reliability and service life of the power metering device 700, and reduce the risk of safety accidents caused by high temperature.

[0097] The exhaust fan 500 is detachably mounted on the mounting bracket 400, with the air inlet of the exhaust fan 500 facing the inside of the housing 100 and the air outlet of the exhaust fan 500 facing the air outlet 120. The detachable design allows the exhaust fan 500 to be easily removed from the housing 100 when maintenance or repair is required.

[0098] Furthermore, the mounting bracket 400 may include a first abutment portion 410 and a second abutment portion 420, which are spaced apart. The exhaust fan 500 may be provided with a fan bracket 510, which is disposed between the first abutment portion 410 and the second abutment portion 420, for fixing the exhaust fan 500 through the first abutment portion 410 and the second abutment portion 420.

[0099] The first abutting part 410 may be provided with a first mounting groove 411, which faces the second abutting part 420 and is used to accommodate at least part of the fan bracket 510. One end of the fan bracket 510 may be partially locked in the first mounting groove 411.

[0100] The first abutting part 410 may be provided with a first locking member 412. The first locking member 412 is movably disposed in the first abutting part 410 and achieves the locking function through threaded engagement and rotational movement.

[0101] The first locking element 412 may include a sleeve 4121, a screw 4122, and an adjusting knob 4123. The sleeve 4121 may have an internal thread and be fixed to the first abutment portion 410. The upper half of the screw 4122 may have an external thread that matches the internal thread of the sleeve 4121. The lower half of the screw 4122 may be a smooth rod for insertion into the limiting hole 511 of the fan bracket 510 to fix the fan bracket 510. The adjusting knob 4123 may be fixedly connected to one end of the screw 4122 near the upper half.

[0102] When it is necessary to fix the fan bracket 510, the adjustment knob 4123 can be rotated to drive the screw 4122 to move downward along the internal thread of the sleeve 4121. The smooth rod part of the screw 4122 is inserted into the limiting hole 511 of the fan bracket 510, and the first abutment part 410 and the fan bracket 510 are fixed by axial limiting.

[0103] When it is necessary to disassemble the fan bracket 510, the adjustment knob 4123 can be rotated in the opposite direction to disengage the external thread of the screw 4122 from the internal thread of the sleeve 4121, and the smooth rod part of the screw 4122 disengages from the limiting hole 511 of the fan bracket 510, thus achieving quick disassembly.

[0104] Alternatively, the second abutment portion 420 may be provided with a second mounting groove 421, which faces the first abutment portion 410 and is used to accommodate at least a portion of the fan bracket 510. One end of the fan bracket 510 may be partially engaged in the second mounting groove 421.

[0105] The second abutment portion 420 may be provided with a second locking member 422. The second locking member 422 is movably disposed in the second abutment portion 420 and achieves the locking function through threaded engagement and rotational movement.

[0106] Alternatively, the first abutment portion 410 and the second abutment portion 420 may be respectively provided with a first mounting groove 411 and a second mounting groove 421. The first mounting groove 411 and the second mounting groove 421 are arranged facing each other. One end of the fan bracket 510 is engaged in the first mounting groove 411, and the other end is engaged in the second mounting groove 421. The first abutment portion 410 may be provided with a first locking member 412, and the second abutment portion 420 may be provided with a second locking member 422. The first locking member 412 and the second locking member 422 may be arranged facing each other to form a bidirectional locking, fixing the first abutment portion 410, the second abutment portion 420, and the fan bracket 510.
