Description

Technical Field

[0001] The present invention relates to the technical field of meter boxes, and in particular to a meter box of a distribution network. Background Art

[0002] The meter box of the distribution network is a device used in the power system, mainly used to measure and monitor the use of electricity. With the popularization of outdoor power equipment and the increase in electricity demand, considering that the normal operation of the electrical appliances inside the meter box is increasingly threatened by humid environments such as rain and fog outdoors, the requirements for waterproofing of the meter box are gradually increasing. Most of the existing electricity meter boxes generally have a ventilation structure. To ensure the dryness inside the meter box, a common method is to use desiccant drying. However, due to the extremely short service life of the desiccant, it needs to be replaced frequently to ensure the drying effect, so as to ensure the quality of ventilation and the stable and reliable operation of the electrical components inside the box. It is not energy-saving and environmentally friendly, and the replacement is too cumbersome and complicated, which is not conducive to the use of the device. In addition, most of the existing electricity meter boxes are made of iron sheets. When the electricity meter box burns or explodes, it is easy to injure the staff, resulting in an increased risk factor for the staff and affecting personal safety.

[0003] Therefore, we make improvements to this and propose a metering box for the distribution network. Summary of the Invention

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

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

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

[0010] As a further solution of the present invention, a square through hole is opened in the middle of the box top, the edge of the through hole is bent upward, and the edge of the glass plate is bent downward and buckled above the square through hole in the box top, and the upper end of the moisture-proof mechanism is arranged close to the bottom surface of the glass plate.

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

[0012] As a further solution of the present invention, the ventilation pipe is a cylinder with a side wall provided with pores having a diameter smaller than that of the dry particles.

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

[0014] The meter box for a distribution network provided by the present invention has the following beneficial effects: 1. A movable moisture-proof mechanism is installed at the upper end of the base, and a large amount of silica gel desiccant is placed inside the moisture-proof mechanism and the ventilation pipe. The silica gel desiccant is filled inside the ventilation pipe to absorb moisture from the sealed meter box to avoid affecting the normal operation of the electrical appliances inside the meter box and causing the meter box to burn out or short-circuit. A driving mechanism is installed inside the ventilation pipe. The piston plate is driven by the rotation of the screw to move up and down inside the ventilation pipe, driving the silica gel desiccant to move up and down, pushing the silica gel desiccant into the moisture-proof mechanism. As the piston plate continues to rise, the piston plate pushes the moisture-proof mechanism upward, and the moisture-proof mechanism and the silica gel desiccant together lift the glass plate upward. After the moisture-proof mechanism is exposed above the top of the box, the side plate is unfolded to expose the silica gel desiccant above the meter, so that the silica gel desiccant can be baked by the external high temperature and exposed to the sun, evaporating the moisture inside the desiccant and restoring the desiccant. This facilitates the reuse of the desiccant, reduces the replacement frequency of the silica gel desiccant, and reduces the workload.

[0015] 2. Since the flap is connected to the moisture-proof mechanism through a push rod, when the piston plate pushes the moisture-proof mechanism up, the connecting belt is loosened, so the push rod swings and drives the flap to expand 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, making it easy to quickly dissipate the heat inside the metering box when it is high temperature or when heat dissipation is required, promoting air flow, and facilitating heat dissipation of the metering box.

[0016] 3. By installing the metering equipment on the mounting frame and installing the box body on the outside of the mounting frame, the metering equipment is externally protected by the box body, the power amount is read through the observation holes of the box door and the observation door, and a gap is set between the metering equipment and the box body, which effectively prevents external impact from damaging the metering equipment facilities, ensures that the electric energy meter and current transformer can work normally, reduces costs, and reduces the loss of state-owned assets.

[0020] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0022] The base 1 includes a bottom plate 11, and a mounting frame 12 and a ventilation pipe 14 are fixedly installed on the upper end of the bottom plate 11. The metering device 2 is installed on the side of the mounting frame 12. A heat dissipation groove 13 is provided in the middle of the mounting frame 12 and the ventilation pipe 14, and a partition 15 is fixedly connected to the upper end of the mounting frame 12 and the ventilation pipe 14. By installing the metering device 2 on the mounting frame 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.

[0023] The moisture-proof mechanism 7 includes a tray 71, and a discharge port 74 is opened in the middle of the tray 71. The discharge port 74 is connected to the upper end of the ventilation pipe 14. The four sides of the tray 71 are hinged with side panels 72, and a connecting piece 73 is pulled out and connected in the middle of two adjacent side panels 72. The tray 71 is installed on the partition 15, and the silica gel desiccant is filled through the tray 71 and the ventilation pipe 14, so that the silica gel desiccant dehumidifies and absorbs moisture inside the metering box, ensuring the normal operation of the metering equipment inside the metering box.

[0024] The box body 3 includes a frame 31, and the frame 31 is hinged with a box door 32 and an observation door 33 on the left and right respectively. A mounting opening 34 is opened at the upper end of the frame 31, and the air vent 4 is installed inside the mounting opening 34. The box 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 box door 32 and the observation door 33 are also convenient for directly taking readings of the measuring device.

[0025] The ventilation window 4 includes a flap 41, a connecting piece 42 is fixedly installed in the middle of the flap 41, a push rod 43 is connected to the connecting piece 42, the bottom end of the push rod 43 is connected to a connecting belt 47, the bottom end of the connecting belt 47 is fixedly connected to the bottom surface of the moisture-proof mechanism 7, a slide groove 44 is installed in the middle of the push rod 43, a support frame 45 is slidably installed in the middle of the slide 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 a connecting rod 46, the other end of the connecting rod 46 is connected and fixed to the frame wall of the frame 31, the flap 41 is movably installed on the mounting port 34, and is linked with the moisture-proof mechanism 7 to ensure ventilation and heat dissipation above the metering box and avoid heat accumulation inside the metering box.

[0026] A square through hole is opened in the middle of the box top 5, the edge of the through hole is bent upward, and the edge of the glass plate 6 is bent downward and buckled above the square through hole of the box top 5. The upper end of the moisture-proof mechanism 7 is arranged close to the bottom surface of the glass plate 6. The box top 5 is at 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 opened upward from the box top 5, it is convenient to dissipate heat of the metering box and to restore the moisture-proof mechanism 7 and the desiccant by exposure to the sun.

[0027] The driving mechanism 8 includes a screw 81, the upper end of which is connected to a connecting buckle 82, which is movably connected to the glass plate 6, and the middle thread of the screw 81 is connected to a piston plate 83, which is installed inside the ventilation pipe 14. A gear 84 is fixedly installed at the bottom of the screw 81, which is meshed with the motor 9. The bottom of the screw 81 is driven by the motor 9 to make the piston plate 83 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, and evenly absorbs the moisture inside the metering box through the ventilation pipe 14, keeping the inside of 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 squeeze into the moisture-proof mechanism 7, and finally, as the moisture-proof mechanism 7 moves upward, it is exposed to the top of the metering box. It is baked at high temperature and exposed to the sun on the outside of the metering box to evaporate the moisture inside the desiccant, thereby reducing the desiccant.

[0028] The ventilation pipe 14 is a cylinder with a side wall provided with pores having a diameter smaller than that of the dry particles. The ventilation pipe 14 is filled with a desiccant to process the moisture inside the metering box and prevent the desiccant from escaping.

[0029] 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 end of the discharge port 74, it drives the moisture-proof mechanism 7 to move upward from the box top 5 and unfolds the side plate 72 at the upper end of the box top 5 to expand the contact area between the moisture-proof mechanism 7 and sunlight, thereby facilitating the evaporation of moisture in the desiccant inside the moisture-proof mechanism 7.

[0030] Specifically, when the meter box of the power distribution network is in use: a large amount of silica gel desiccant is placed inside the moisture-proof mechanism 7 and the ventilation pipe 14, and the silica gel desiccant is filled inside the ventilation pipe 14 to absorb moisture from the sealed inside of the meter box to ensure the dryness of the inside of the meter 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, and as the piston plate 83 continues to rise, the piston plate 83 pushes the moisture-proof mechanism 7 upward, and the moisture-proof mechanism 7 together with the silica gel desiccant lifts the glass plate 6 upward, and after the moisture-proof mechanism 7 is exposed above the box top 5, the side plate 72 is unfolded to expose the silica gel desiccant above the meter, and the silica gel desiccant is subjected to external high temperature baking and sun exposure, and the steam The moisture inside the desiccant is released and the desiccant is restored, which facilitates the reuse of the desiccant and reduces the replacement frequency of the silica gel desiccant. In addition, since the flap 41 is connected to the moisture-proof mechanism 7 through the push rod 43, when the piston plate 83 pushes the moisture-proof mechanism 7 to rise, the connecting belt 47 is loosened, and the push rod 43 swings to drive the flap 41 to expand to the outside of the box body 3, opening the position of the installation port 34. At the same time, the glass plate 6 and the moisture-proof mechanism 7 are also opened upward, which is convenient for quickly dissipating the heat inside the metering box when high temperature or heat dissipation is required, promoting air flow, and the box body 3 provides external protection for the metering device 2. The power is read at the observation holes of the box door 32 and the observation door 33. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
