Description

Technical Field

[0001] This invention relates to the field of metering box technology, and more particularly to a metering box for power distribution networks. Background Technology

[0002] Metering boxes in power distribution networks are devices used in power systems, primarily for measuring and monitoring electricity usage. With the increasing prevalence of outdoor power equipment and rising electricity demand, and considering the growing threat posed by damp environments such as rain and fog to the normal operation of electrical components inside the metering boxes, the requirements for waterproofing have become increasingly stringent. Most existing electricity metering boxes have ventilation structures, and desiccants are commonly used to ensure dryness inside. However, desiccants have a very short lifespan and require frequent replacement to maintain drying effectiveness, ensure ventilation quality, and guarantee the stable and reliable operation of internal electrical components. This method is not energy-efficient or environmentally friendly, and replacement is cumbersome and complex, hindering device use. Furthermore, most existing electricity metering boxes are made of sheet metal, which can easily injure workers in the event of internal combustion or explosion, increasing the risk to their safety.

[0003] Therefore, we have made improvements to this and proposed a metering box for power distribution networks. Summary of the Invention

[0004] The purpose of this invention is to provide a metering box for a power distribution network to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, the present invention provides a metering box for a power distribution network, comprising a base, a box body mounted on the upper end of the base, a box top fixedly mounted on the top of the box body, metering devices mounted on the four sides of the base, a moisture-proof mechanism movably mounted on the upper end of the base, a rotating drive mechanism disposed in the middle of the base, a motor connected to the bottom end of the drive mechanism, and a glass plate rotatably connected to the upper end of the drive mechanism.

[0006] As a further embodiment of the present invention, the base includes a base plate, an mounting bracket and a ventilation pipe are fixedly mounted on the upper end of the base plate, a metering device is mounted on the side of the mounting bracket, a heat dissipation groove is provided between the mounting bracket and the ventilation pipe, and a partition is fixedly connected to the upper end of the mounting bracket and the ventilation pipe.

[0007] As a further embodiment of the present invention, the moisture-proof mechanism includes a tray with a discharge port in the middle of the tray, the discharge port being connected to the upper end of the ventilation pipe, and side plates hinged to the four sides of the tray, with a connecting piece pulled out between two adjacent side plates.

[0008] As a further embodiment of the present invention, the box body includes a frame, with a box door and an observation door respectively hinged to the left and right sides of the frame, and an installation opening is provided at the upper end of the frame, with the ventilation window installed inside the installation opening.

[0009] As a further embodiment of the present invention, the ventilation window includes a flap, a connector is fixedly installed in the middle of the flap, a push rod is connected to the connector, a connecting strip is connected to the bottom end of the push rod, the bottom end of the connecting strip is fixedly connected to the bottom surface of the moisture-proof mechanism, a sliding groove is installed in the middle of the push rod, a support frame is slidably installed in the middle of the sliding groove, the bottom end of the support frame is fixedly installed on the base, and connecting rods are hinged to both ends of the flap, with the other end of the connecting rods connected and fixed to the frame wall of the frame.

[0010] As a further embodiment of the present invention, a square through hole is provided in the middle of the top of the box, the edge of the through hole is bent upward, and the edge of the glass plate is bent downward and fastened above the square through hole on the top of the box. The upper end of the moisture-proof mechanism is set close to the bottom surface of the glass plate.

[0011] As a further embodiment of the present invention, the driving mechanism includes a screw, the upper end of which is connected to a connecting buckle, the connecting buckle being movably connected to a glass plate, a piston plate being threadedly connected to the middle of the screw, the piston plate being installed inside a ventilation pipe, and a gear being fixedly installed at the bottom of the screw, the gear being meshed with a motor.

[0012] As a further embodiment of the present invention, the ventilation pipe is a cylinder with fine holes on its sidewalls having a diameter smaller than that of the dry particles.

[0013] As a further embodiment of the present invention, the piston plate has the same diameter as the ventilation pipe and is also larger than the diameter of the discharge port.

[0014] The metering box for a power distribution network provided by this invention has the following advantages:

[0015] 1. By installing a movable moisture-proof mechanism at the top of the base, and placing a large amount of silica gel desiccant inside the moisture-proof mechanism and ventilation duct, the silica gel desiccant fills the inside of the ventilation duct to absorb the initial moisture inside the sealed metering box, preventing it from affecting the normal operation of the electrical components inside the metering box and causing the metering box to burn out or short-circuit. Furthermore, a drive mechanism is installed inside the ventilation duct. The piston plate, driven by the rotation of the screw, moves up and down inside the ventilation duct, causing the silica gel desiccant to move up and down, pushing it into the moisture-proof mechanism. As the piston plate rises, it pushes the moisture-proof mechanism upwards, lifting the glass plate along with the silica gel desiccant. After the moisture-proof mechanism is exposed above the top of the box, the side plate unfolds, exposing the silica gel desiccant above the metering device. This allows the silica gel desiccant to be exposed to high temperatures and sunlight, evaporating the moisture inside the desiccant and restoring it to its original state. This facilitates the reuse of the desiccant, reduces the frequency of silica gel desiccant replacement, and decreases workload.

[0016] 2. Since the flap is connected to the moisture-proof mechanism via the push rod, when the piston plate pushes the moisture-proof mechanism upward, the connecting belt is released. Therefore, the push rod swings and drives the flap to unfold to the outside of the box, opening the installation port. At the same time, the glass plate and the moisture-proof mechanism also open upward, which facilitates the rapid dissipation of heat from the metering box when it is hot or needs to dissipate heat, promotes airflow, and facilitates heat dissipation of the metering box.

[0017] 3. By installing the metering equipment on the mounting frame and installing a box on the outside of the mounting frame, the metering equipment is externally protected by the box. The electricity is read through the observation holes of the box door and observation door. Furthermore, a gap is set between the metering equipment and the box to effectively prevent external impacts from damaging the metering equipment. This ensures that the electricity meter and current transformer can work normally, reduces costs, and minimizes the loss of state-owned assets. Attached Figure Description

[0028] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] like Figures 1-8 As shown, this embodiment proposes a metering box for a power distribution network, including a base 1, a box body 3 installed on the upper end of the base 1, a box top 5 fixedly installed on the top of the box body 3, metering devices 2 installed on the four sides of the base 1, a moisture-proof mechanism 7 movably installed on the upper end of the base 1, a rotating drive mechanism 8 set in the middle of the base 1, a motor 9 connected to the bottom end of the drive mechanism 8, and a glass plate 6 rotatably connected to the upper end of the drive mechanism 8.

[0030] The base 1 includes a base plate 11. A mounting bracket 12 and a ventilation pipe 14 are fixedly installed on the upper end of the base plate 11. A metering device 2 is installed on the side of the mounting bracket 12. A heat dissipation groove 13 is provided between the mounting bracket 12 and the ventilation pipe 14. A partition 15 is fixedly connected to the upper end of the mounting bracket 12 and the ventilation pipe 14. By installing the metering device 2 on the mounting bracket 12, it is convenient to position and protect the metering device 2, avoid the metering device 2 being directly exposed to the outside of the metering box, and increase the risk resistance of the metering device.

[0031] The moisture-proof mechanism 7 includes a tray 71 with a discharge port 74 in the middle, which is connected to the upper end of the ventilation pipe 14. Each of the four sides of the tray 71 is hinged with a side plate 72, and a connecting piece 73 is pulled out between two adjacent side plates 72. The tray 71 is installed on the partition 15. Silica gel desiccant is filled through the tray 71 and the ventilation pipe 14, allowing the silica gel desiccant to dehumidify and absorb moisture inside the metering box, ensuring the normal operation of the metering equipment inside the metering box.

[0032] The housing 3 includes a frame 31, with a door 32 and an observation door 33 hinged to the left and right sides of the frame 31 respectively. The upper end of the frame 31 has an installation opening 34, and a ventilation window 4 is installed inside the installation opening 34. The door 32 and the observation door 33 are locked to the outside of the measuring device 2 for easy maintenance, and the observation openings on the door 32 and the observation door 33 also facilitate direct reading of the measuring device.

[0033] The ventilation window 4 includes a flap 41, a connector 42 fixedly installed in the middle of the flap 41, a push rod 43 connected to the connector 42, a connecting strap 47 connected to the bottom end of the push rod 43, and the bottom end of the connecting strap 47 fixedly connected to the bottom surface of the moisture-proof mechanism 7. A sliding groove 44 is installed in the middle of the push rod 43, and a support frame 45 is slidably installed in the middle of the sliding groove 44. The bottom end of the support frame 45 is fixedly installed on the base 1. Both ends of the flap 41 are hinged with connecting rods 46, and the other end of the connecting rods 46 is fixedly connected to the frame wall of the frame 31. The flap 41 is movably installed on the installation port 34 and moves in conjunction with the moisture-proof mechanism 7 to ensure ventilation and heat dissipation above the metering box and prevent heat accumulation inside the metering box.

[0034] A square through hole is provided in the middle of the top of the box 5. The edge of the through hole is bent upward, and the edge of the glass plate 6 is bent downward and fastened above the square through hole of the top of the box 5. The upper end of the moisture-proof mechanism 7 is set close to the bottom surface of the glass plate 6. The top of the box 5 is on the top of the metering box and together with the glass plate 6, it protects the metering box from rain. After the glass plate 6 is pushed upward and opened with the top of the box 5, it is convenient for the metering box to dissipate heat and for the moisture-proof mechanism 7 and the desiccant to be exposed to sunlight.

[0035] The drive mechanism 8 includes a screw 81, with a connecting buckle 82 connected to the upper end of the screw 81. The connecting buckle 82 is movably connected to the glass plate 6. A piston plate 83 is threadedly connected to the middle of the screw 81. The piston plate 83 is installed inside the ventilation pipe 14. A gear 84 is fixedly installed at the bottom of the screw 81. The gear 84 meshes with the motor 9. The bottom of the screw 81 is driven by the motor 9, causing the piston plate 83 to slide on the screw 81. When the piston plate 83 slides to the bottom of the ventilation pipe 14, all the desiccant inside the moisture-proof mechanism 7 enters the ventilation pipe 14. The ventilation pipe 14 evenly absorbs the moisture inside the metering box, keeping the metering box dry. When the screw 81 drives the piston plate 83 to move upward, the desiccant above the piston plate 83 will gradually be squeezed into the moisture-proof mechanism 7. Finally, as the moisture-proof mechanism 7 moves upward, it is exposed to the top of the metering box. After being baked at high temperature and exposed to the sun on the outside of the metering box, the moisture inside the desiccant evaporates, and the desiccant is restored.

[0036] The ventilation duct 14 is a cylinder with fine holes on its side wall that are smaller than the diameter of the dry particles. The ventilation duct 14 is filled with desiccant to treat the moisture inside the metering box and to prevent the desiccant from falling out.

[0037] The piston plate 83 has the same diameter as the ventilation pipe 14 and is larger than the diameter of the discharge port 74. After the piston plate 83 moves to the bottom of the discharge port 74, it drives the moisture-proof mechanism 7 to move upward to the top of the box 5. The side plate 72 is unfolded at the top of the box 5 to expand the contact area between the moisture-proof mechanism 7 and sunlight, so as to facilitate the evaporation of moisture from the desiccant inside the moisture-proof mechanism 7.

[0038] Specifically, when using the metering box of this power distribution network: a large amount of silica gel desiccant is placed inside the moisture-proof mechanism 7 and the ventilation pipe 14. The silica gel desiccant fills the inside of the ventilation pipe 14 to absorb the initial moisture inside the sealed metering box, ensuring the dryness of the inside of the metering box. When encountering hot and sunny weather, the screw 81 drives the piston plate 83 to move upward along the ventilation pipe 14, pushing the silica gel desiccant into the inside of the moisture-proof mechanism 7. As the piston plate 83 continues to rise, it pushes the moisture-proof mechanism 7 upward, lifting the glass plate 6 along with the silica gel desiccant. After the moisture-proof mechanism 7 is exposed above the top 5 of the box, the side plate 72 is unfolded, exposing the silica gel desiccant above the metering device. The silica gel desiccant is exposed to the high temperature and sunlight, causing it to evaporate. The desiccant is dehydrated and its moisture is reduced, facilitating its reuse and reducing the frequency of silica gel desiccant replacement. Since the flap 41 is connected to the moisture-proof mechanism 7 via the push rod 43, when the piston plate 83 pushes the moisture-proof mechanism 7 upwards, the connecting strap 47 loosens, and the push rod 43 swings, causing the flap 41 to unfold outwards from the housing 3, opening the mounting port 34. Simultaneously, the glass plate 6 and the moisture-proof mechanism 7 also open upwards, facilitating the rapid dissipation of heat from the metering chamber in high-temperature conditions or when heat dissipation is required, promoting airflow. The housing 3 provides external protection for the metering device 2. Electrical readings are performed through the observation holes on the door 32 and the observation door 33. Content not described in detail in this specification is prior art known to those skilled in the art.

[0039] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
