Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, in particular to a meter inlet wiring device of an electric power meter box. Background Art

[0002] At the user end of power transmission, an electric meter needs to be installed to measure the user's electricity consumption. This kind of electric meter often requires a corresponding meter box to cooperate with it. At the same time, a piece of equipment is usually required next to the electric meter to install the incoming switch and the outgoing switch, and to arrange the incoming and outgoing wiring of the electric meter.

[0003] The patent with the patent announcement number CN205210151U discloses a wiring device for the meter input of the electric meter box, including an electric meter, a mounting plate, a guide groove, a meter input wiring, a wire pressing device, a meter output wiring, a card slot, an on-off switch, a wiring terminal, an inlet switch connector, a fixing hole, a reinforcing plate and an outlet switch connector. The electric meter is installed on the upper part of the mounting plate through the guide groove; the meter input wiring or the meter output wiring is connected to the on-off switch through the wire pressing device; the on-off switch is installed in the middle of the mounting plate through the card slot; the wiring terminal is connected to the on-off switch through the inlet switch connector; and the fixing hole is set on the reinforcing plate. The setting of the guide groove, the meter output wiring and the wire pressing device of the patent is conducive to adjusting the installation structure, improving the installation efficiency, ensuring safety and reliability, and facilitating market promotion and application.

[0004] However, the device still has some shortcomings: the device effectively improves the installation efficiency between the wires and the meter box, but after installation in the factory area, the back of the meter box is against the wall. When acid rain comes, the corrosive rainwater remaining on the wall can easily corrode the meter box for a long time, causing excessive moisture inside the meter box, thereby corroding the surface of the wires and the exposed parts of the lines, increasing the risk of short circuit between the lines and the meter box. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a meter-in wiring device for an electric power meter box, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an inlet wiring device for an electric power meter box, comprising a device body, square grooves are arranged on the left and right sides of the device body, a wire entry hole is arranged at the bottom of the device body, a safety door is arranged on the front of the device body, a meter is arranged inside the device body, a power component is arranged at the bottom of the meter, and a mounting component is arranged at the bottom of the power component; An anti-falling device is arranged inside the device body, an anti-penetration device is arranged outside the anti-falling device, and an anti-drip device is arranged above the anti-penetration device; The anti-falling device comprises a circular frame, the bottom of which is fixedly mounted on the bottom of the inner wall of the device body, a plurality of support plates are arranged inside the circular frame, and the plurality of support plates are symmetrically and fixedly distributed inside the circular frame, an elastic telescopic plate is hinged on the top of the support plate, a torsion spring is arranged between the bottom of the elastic telescopic plate and the support plate, a limiting arc plate is fixedly mounted on the top of the telescopic end of the elastic telescopic plate, and the limiting arc plate is located between the mounting hole of the device body and the mounting assembly, two dehumidification assemblies are fixedly mounted on the bottom of the inner wall of the device body, the dehumidification assembly is located on the front of the circular frame, and the inner wall of the device body Two electric reciprocating screws are rotatably installed at the bottom, and sliding plates are movably installed on the outer walls of the two electric reciprocating screws. The sliding plates are slidably installed on the outer wall of the dehumidification component close to the axis of the device body. A round rod is fixedly installed on the inner wall of the square groove of the device body, and a sealing plate is hinged on the outer wall of the round rod through a torsion spring. A T-shaped arc block is fixedly installed on the side of the sealing plate close to the axis of the device body. The staff installs the back of the device body on the wall through the fixing assembly, and then inserts the wires into the inside of the device body through the wire entry hole at the bottom of the device body. When the outer wall of the wire contacts the inner wall of the limit arc plate, a resistance force is generated. At this time, the limit arc plate guides the wire vertically, and the wire pulls the limit arc plate upward through the resistance force, and the limit arc plate pulls the telescopic end of the elastic telescopic plate to move synchronously. The elastic telescopic plate is limited by the support plate, and the support plate is limited by the circular frame. Later, when the top of the wire enters the inside of the power component, the staff fixes the wire through the installation component, and then records the power consumption through the meter. When the wire is in the preset position of the limit arc plate, the limit arc plate causes the hinge shaft of the elastic telescopic plate to start rotating through the resistance force, and rotates away from the center of the installation component; at the same time, when acid rain comes , or the staff regularly turns on the dehumidification component through the intelligent signal transmission of the information module, and the dehumidification component draws out the moisture that has invaded the inside of the device body, and at the same time the electric reciprocating screw is started. When the electric reciprocating screw rotates, it limits the built-in block of the sliding plate through the reciprocating spiral groove on its own outer wall, and the electric reciprocating screw drives the sliding plate to slide upward along its own outer wall and reset. When the sliding plate slides upward, it hits the arc surface of the T-shaped arc block. At this time, the T-shaped arc block pushes the sealing plate to flip along the outer wall of the round rod away from the outer wall of the device body through the resistance of the sliding plate, and the sealing plate opens the cover to the inside of the device body, and then the sealing plate is reset by the torsion spring.

[0007] According to the above technical solution, the two dehumidification components are symmetrically distributed around the axis of the device body, the two electric reciprocating screws rotate in the same direction, and the T-shaped arc block is located on the movement trajectory of the sliding plate close to the axis of the device body.

[0008] According to the above technical scheme, the anti-infiltration device includes a contact plate, a vertical plate and a plurality of tough plates. The contact plate is fixedly installed on the back of the sliding plate on the side away from the back of the inner wall of the device body, and the vertical plate is fixedly installed on the outer wall of the circular frame on the side close to the axis of the device body. Several of the tough plates are equidistant and fixedly installed on the front of the vertical plate on the side close to the back of the inner wall of the device body. The tough plate is located on the movement trajectory of the contact plate. When the sliding plate moves upward, it drives the contact plate to move synchronously. The circular frame limits the vertical plate to force it to remain stationary. At the same time, the vertical plate limits the tough plate. When the contact plate moves upward, it contacts the edge of the tough plate. The two are guided by their own arc surfaces to cause the tough plate to bend and deform under the friction during the movement of the contact plate. When the contact plate passes over the tough plate, the tough plate will swing back and forth to generate vibration through its own toughness reset process, and the circular frame will vibrate through the transmission of force.

[0009] According to the above technical scheme, the anti-infiltration device also includes a U-shaped plate, a wave plate, a plurality of rotating rods and an extrusion wheel. The top of the U-shaped plate close to the back side of the device body is fixedly installed on the bottom of the resistance plate, the bottom of the wave plate is fixedly installed on the bottom of the inner wall of the U-shaped plate, and the ends of the plurality of rotating rods close to the axis of the device body are rotatably installed on the outer wall of the U-shaped plate. The extrusion wheel is fixedly installed on the outer wall of the rotating rod close to the axis of the device body. When the resistance plate drives the U-shaped plate to move upward, the U-shaped plate drives the wave plate to move synchronously. During the upward movement and resetting process of the wave plate, the air around the dehumidification component is disturbed by its own wave surface. At the same time, the U-shaped plate drives the rotating rod to move synchronously. The rotating rod drives the extrusion wheel to slide and rub along the outer wall of the sealing strip at the back edge of the safety door, that is, between the safety door and the device body, to generate a rotational force, thereby the extrusion wheel starts to rotate through friction.

[0010] According to the above technical solution, the U-shaped plate is located outside the dehumidification component, and the plurality of rotating rods are evenly distributed on the outer wall of the U-shaped plate, and the outer wall of the extrusion wheel contacts the edge of one side of the back of the safety door.

[0011] According to the above technical scheme, the anti-drip device includes a transmission plate, a support rod and a drying plate. The bottom of the transmission plate is hinged to the outer wall of the U-shaped plate through a torsion spring near the axis of the device body. Both ends of the support rod are fixedly installed on the inner wall of the device body. The transmission plate moves inside and penetrates the outer wall of the support rod. The drying plate is hinged to the inner wall of the transmission plate near the inner wall of the device body, and the top of the drying plate is slidably connected to the inner wall of the device body. The drying plate is hollow in design, and a desiccant is provided inside the drying plate. When the U-shaped plate moves upward, it drives the transmission plate to move synchronously. The transmission plate is limited by the support rod and pushed by the U-shaped plate, so that the support rod is flipped back to the back of the inner wall of the device body, so that the hinge shaft between the transmission plate and the drying plate starts to rotate, and the drying plate is prompted to slide backward along the top of the inner wall of the device body, and the drying plate slides and rubs against the top of the inner wall of the device body.

[0012] According to the above technical solution, the anti-drip device also includes a friction column, a screw, a sliding ring, a U-shaped guide plate, a plurality of hollow arc pieces and an elastic telescopic rod. The friction column is rotatably installed inside the drying plate on the side away from the axis of the device body, and both ends of the screw are fixedly installed on the side of the friction column close to the axis of the drying plate. The internal thread of the sliding ring is connected to the outer wall of the screw, and the bottom of the U-shaped guide plate is slidably installed on the bottom of the inner wall of the drying plate. The side of the plurality of hollow arc pieces away from the screw is fixedly installed on the outer wall of the U-shaped guide plate, and the side of the elastic telescopic rod close to the screw is fixedly installed on the U-shaped guide plate At the inner wall, the drying plate drives the friction column to slide along the top of the inner wall of the device body to generate friction. The friction column starts to rotate due to the friction and drives the screw to rotate. The screw drives the threaded sliding ring to slide along its own outer wall through the spiral groove. When the sliding ring slides, it contacts the arc surface of the hollow arc piece. At this time, the hollow arc piece generates a force moving away from the outer wall of the screw through the resistance force. The hollow arc piece pushes the U-shaped guide plate to slide synchronously along the bottom of the inner wall of the drying plate. At the same time, the U-shaped guide plate pushes the elastic telescopic rod to move synchronously. The telescopic end of the elastic telescopic rod contracts toward the inside of its fixed end through the limit of the drying plate.

[0013] According to the above technical solution, the outer wall of the friction column contacts the top of the inner wall of the device body, a plurality of the hollow arc pieces are equidistantly distributed on the outer wall of the U-shaped guide plate, the arc surface of the hollow arc piece is located on the motion trajectory of the sliding ring, and the telescopic end of the elastic telescopic rod is fixedly installed inside the drying plate.

[0014] The present invention provides a wiring device for an electric power meter box. It has the following beneficial effects: (1) The present invention ensures accurate wiring of the meter through the arrangement of an anti-falling device, through the coordination of a circular frame, a support plate, an elastic expansion plate, a limit arc plate, a dehumidification component, an electric reciprocating screw, a sliding plate, a round rod, a sealing plate and a T-shaped arc block, thereby reducing the number of times the wires collide and improving the wiring efficiency. At the same time, the limit arc plate and the elastic expansion plate are used to adaptively stabilize wires of different thicknesses, thereby reducing the risk of the wires falling off after being fixed inside the installation component and being disturbed by external forces; at the same time, the sealing plate is used to change the sealing environment inside the device body, so that the dehumidification component can quickly discharge moisture from the inside of the device body, thereby preventing the device body from being eroded by acid rain when it is backed against the wall, resulting in excessive moisture inside the device body, thereby eroding the wire skin and the exposed part of the wire, and increasing the risk of short circuit between the line and the meter.

[0015] (2) The present invention sets an anti-seepage device, and cooperates with a sliding plate, a contact plate, a vertical plate, a tough plate, a U-shaped plate, a wave plate, a rotating rod and an extrusion wheel to cause the circular frame to generate and slightly vibrate the limit arc plate through vibration force. The limit arc plate causes the wire to vibrate synchronously, so as to detect whether the wire and the installation component have a tendency to fall off due to loose connection. The staff can judge whether the device as a whole is operating normally through the change range of the power transmission curve to avoid abnormal measurement of the meter due to increased resistance; and rely on the wave plate to accelerate the circulation speed of air around the dehumidification component, effectively improve the dehumidification effect, and avoid moisture falling and depositing on the bottom of the inner wall of the device body under the influence of its own gravity. At the same time, the extrusion wheel rolls and squeezes the sealing strip, reducing the wear of the sealing strip while avoiding the sealing effect of the sealing strip due to aging of the safety door, which causes rainwater to penetrate into the inside of the device body.

[0016] (3) The present invention adopts the arrangement of an anti-drip device, and cooperates with a U-shaped plate, a transmission plate, a support rod, a drying plate, a friction column, a screw, a sliding ring, a U-shaped guide plate, a hollow arc plate and an elastic telescopic rod. The drying plate wipes off the heat generated by the operation of the meter and the cooling caused by rainwater on the top of the inner wall of the device body, thereby preventing the water droplets from dripping onto the outer wall surface of the wire for a long time, causing the wire to further accelerate the oxidation speed when it is heated during operation, thereby extending the service life of the wire and reducing the risk of exposure. At the same time, the U-shaped guide plate gathers the desiccant particles inside the drying plate, and the elastic telescopic rod stirs the desiccant particles back and forth, thereby ensuring that the desiccant can evaporate evenly and improving the desiccant's absorption and drying efficiency of water vapor, ensuring that the water vapor can be quickly neutralized by the desiccant to avoid the occurrence of excessive local use of the drying plate.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 8 One embodiment of the present invention is: a meter-in wiring device for an electric power meter box, comprising a device body 1, square grooves are arranged on the left and right sides of the device body 1, a wire-in hole is arranged at the bottom of the device body 1, a safety door 11 is arranged at the front of the device body 1, a meter 2 is arranged inside the device body 1, a power component 3 is arranged at the bottom of the meter 2, and a mounting component 31 is arranged at the bottom of the power component 3; An anti-dropping device 4 is provided inside the device body 1, an anti-penetration device 5 is provided outside the anti-dropping device 4, and an anti-drip device 6 is provided above the anti-penetration device 5; The anti-falling device 4 includes a circular frame 41, the bottom of the circular frame 41 is fixedly installed on the bottom of the inner wall of the device body 1, a plurality of support plates 42 are arranged inside the circular frame 41, and the plurality of support plates 42 are symmetrically and fixedly distributed inside the circular frame 41, an elastic telescopic plate 43 is hinged on the top of the support plate 42, a torsion spring is arranged between the bottom of the elastic telescopic plate 43 and the support plate 42, a limiting arc plate 44 is fixedly installed on the top of the telescopic end of the elastic telescopic plate 43, and the limiting arc plate 44 is located between the mounting hole of the device body 1 and the mounting component 31, two dehumidification components 45 are fixedly installed on the bottom of the inner wall of the device body 1, and the dehumidification components 45 are located on the front of the circular frame 41, and two electric reciprocating screws 46 are rotatably installed on the bottom of the inner wall of the device body 1, and the outer walls of the two electric reciprocating screws 46 are movably installed with sliding plates 47, and the sliding plates 47 are slidably installed on the side of the dehumidification component 4 close to the axis of the device body 1 5, a round rod 48 is fixedly installed on the upper inner wall of the square groove of the device body 1, and a sealing plate 49 is hinged on the outer wall of the round rod 48 through a torsion spring. A T-shaped arc block 410 is fixedly installed on the sealing plate 49 close to the axis of the device body 1. The above cooperation ensures the accurate wiring of the meter 2, reduces the number of collisions of the wires, and improves the wiring efficiency. At the same time, the limiting arc plate 44 and the elastic expansion plate 43 are adaptively stabilized to wires of different thicknesses, thereby reducing the risk of the wires falling off after being fixed inside the installation component 31 and being disturbed by external forces; through the above cooperation, the sealing environment inside the device body 1 is changed by relying on the sealing plate 49, which facilitates the dehumidification component 45 to quickly discharge the moisture inside the device body 1, and prevents the device body 1 from being eroded by acid rain when it is backed against the wall, resulting in excessive moisture inside itself, thereby corroding the wire skin and the exposed part of the wire, and increasing the risk of short circuit between the line and the meter 2.

[0021] The two dehumidification components 45 are symmetrically distributed around the axis of the device body 1 , the two electric reciprocating screws 46 rotate in the same direction, and the T-shaped arc block 410 is located on the movement track of the sliding plate 47 near the axis of the device body 1 .

[0022] When in use, the staff installs the back of the device body 1 on the wall through the fixing assembly, and then inserts the wires into the device body 1 through the wire entry hole at the bottom of the device body 1. When the outer wall of the wire contacts the inner wall of the limit arc plate 44, a resistance force is generated. At this time, the limit arc plate 44 guides the wire vertically, and the wire pulls the limit arc plate 44 upward through the resistance force, and the limit arc plate 44 pulls the telescopic end of the elastic telescopic plate 43 to move synchronously. The elastic telescopic plate 43 is limited by the support plate 42, and the support plate 42 is limited by the circular frame 41. Later, when the top of the wire enters After the electric power assembly 3 is inside, the staff fixes the wires through the installation assembly 31, and then records the power consumption through the meter 2. When the wires are in the preset position of the limit arc plate 44, the limit arc plate 44 causes the hinge axis of the elastic expansion plate 43 to start rotating through the resistance force, and rotates away from the center of the installation assembly 31. Through the above cooperation, the meter 2 is accurately wired, the number of wire collisions is reduced, and the wiring efficiency is improved. At the same time, the limit arc plate 44 and the elastic expansion plate 43 are adaptively stabilized to stabilize wires of different thicknesses, thereby reducing the wires fixed in the installation assembly. At the same time, when acid rain comes, or the staff regularly turns on the dehumidification component 45 through the intelligent signal transmission of the information module, the dehumidification component 45 draws out the moisture invading the inside of the device body 1, and at the same time the electric reciprocating screw 46 is started. When the electric reciprocating screw 46 rotates, the reciprocating spiral groove on its outer wall limits the built-in block of the sliding plate 47. The electric reciprocating screw 46 drives the sliding plate 47 to slide upward along its outer wall and reset. When the sliding plate 47 slides upward, it contacts the arc surface of the T-shaped arc block 410. At this time, the T-shaped arc block 41 The sealing plate 49 is pushed to flip along the outer wall of the round rod 48 away from the outer wall of the device body 1 through the resistance of the sliding plate 47, and the sealing plate 49 opens the shielding of the inside of the device body 1. Then the sealing plate 49 is reset by the torsion spring. Through the above cooperation, the sealing environment inside the device body 1 is changed by relying on the sealing plate 49, which facilitates the dehumidification component 45 to quickly discharge the moisture inside the device body 1, and prevents the device body 1 from being corroded by acid rain when it is backed against the wall, resulting in excessive moisture inside itself, thereby corroding the wire skin and the exposed part of the wire, and increasing the risk of short circuit between the line and the meter 2.

[0023] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-permeation device 5; The anti-seepage device 5 includes a contact plate 51, a vertical plate 52 and a plurality of flexible plates 53. The contact plate 51 is fixedly mounted on the back of the sliding plate 47 on the side away from the back of the inner wall of the device body 1, and the vertical plate 52 is fixedly mounted on the outer wall of the circular frame 41 on the side close to the axis of the device body 1. A plurality of flexible plates 53 are equidistantly mounted on the front of the vertical plate 52 on the side close to the back of the inner wall of the device body 1. The flexible plates 53 are located on the movement trajectory of the contact plate 51. Through the above coordination, the circular frame 41 causes the limiting arc plate 44 to generate and vibrate slightly through the vibration force, and the limiting arc plate 44 causes the wires to vibrate synchronously to detect whether the wires and the installation component 31 have a tendency to fall off due to loose connection. The staff judges whether the device as a whole is operating normally through the range of changes in the power transmission curve to avoid abnormal measurement of the meter 2 caused by increased resistance.

[0024] The anti-infiltration device 5 also includes a U-shaped plate 54, a wave plate 55, a plurality of rotating rods 56 and an extrusion wheel 57. The top of the U-shaped plate 54 close to the back of the device body 1 is fixedly installed on the bottom of the contact plate 51, the bottom of the wave plate 55 is fixedly installed on the bottom of the inner wall of the U-shaped plate 54, and the ends of the plurality of rotating rods 56 close to the axis of the device body 1 are all rotatably installed on the outer wall of the U-shaped plate 54. The extrusion wheel 57 is fixedly installed on the outer wall of the rotating rod 56 close to the axis of the device body 1. Through the above cooperation, the wave plate 55 is used to accelerate the circulation speed of the air around the dehumidification component 45, effectively improve the dehumidification effect, and prevent moisture from falling and depositing on the bottom of the inner wall of the device body 1 under the influence of its own gravity. At the same time, the extrusion wheel 57 rolls and squeezes the sealing strip, which reduces the wear of the sealing strip and prevents the sealing strip from affecting the sealing effect of the safety door 11 due to aging, causing rainwater to penetrate into the device body 1.

[0025] The U-shaped plate 54 is located outside the dehumidification assembly 45 , and a plurality of rotating rods 56 are evenly distributed on the outer wall of the U-shaped plate 54 . The outer wall of the squeezing wheel 57 contacts the edge of one side of the back side of the safety door 11 .

[0026] When in use, the sliding plate 47 moves upward and drives the contact plate 51 to move synchronously. The circular frame 41 limits the vertical plate 52 to keep it still. At the same time, the vertical plate 52 limits the tough plate 53. When the contact plate 51 moves upward, it contacts the edge of the tough plate 53. The two are guided by their own arc surfaces to cause the tough plate 53 to bend and deform under the resistance during the movement of the contact plate 51. After the contact plate 51 passes over the tough plate 53, the tough plate 53 will swing back and forth and vibrate due to its own toughness in the process of resetting. The transmission of force causes the circular frame 41 to vibrate. The above cooperation causes the circular frame 41 to generate and vibrate the limiting arc plate 44 through the vibration force. The limiting arc plate 44 causes the wires to vibrate synchronously to detect whether the wires and the installation component 31 have a tendency to fall off due to loose connection. The staff can judge whether the overall device is operating normally through the range of changes in the power transmission curve to avoid resistance. The increase causes abnormal measurement of the meter 2; when the contact plate 51 drives the U-shaped plate 54 to move upward, the U-shaped plate 54 drives the wave plate 55 to move synchronously. During the upward movement and resetting process of the wave plate 55, the air around the dehumidification component 45 is disturbed by its own wave surface, and at the same time, the U-shaped plate 54 drives the rotating rod 56 to move synchronously, and the rotating rod 56 drives the extrusion wheel 57 to slide along the edge of the back of the safety door 11, that is, the outer wall of the sealing strip between the safety door 11 and the device body 1 to generate a rotational force, thereby the extrusion wheel 57 starts to rotate due to friction. Through the above cooperation, the wave plate 55 is used to accelerate the circulation speed of the air around the dehumidification component 45, effectively improving the dehumidification effect, and preventing moisture from falling and depositing on the bottom of the inner wall of the device body 1 under the influence of its own gravity. At the same time, the extrusion wheel 57 rolls and squeezes the sealing strip, reducing the wear of the sealing strip while avoiding the sealing effect of the sealing strip due to aging of the safety door 11, which causes rainwater to penetrate into the inside of the device body 1.

[0027] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-drip device 6; The anti-drip device 6 includes a transmission plate 61, a support rod 62 and a drying plate 63. The bottom of the transmission plate 61 is hinged to the outer wall of the U-shaped plate 54 near the axis of the device body 1 through a torsion spring. Both ends of the support rod 62 are fixedly installed on the inner wall of the device body 1. The transmission plate 61 moves inside and penetrates the outer wall of the support rod 62. The drying plate 63 is hinged to the inner wall of the transmission plate 61 near the inner wall of the device body 1, and the top of the drying plate 63 is slidably connected to the inner wall of the device body 1. The drying plate 63 is hollow in design, and a desiccant is arranged inside the drying plate 63. Through the above cooperation, the drying plate 63 is used to wipe off the heat generated by the operation of the meter 2 on the top of the inner wall of the device body 1, and the cooling caused by rainwater, thereby atomizing and condensing into water droplets, thereby preventing the water droplets from dripping onto the outer wall surface of the wire for a long time, causing the wire to further accelerate the oxidation speed when it is hot during operation, thereby extending the service life of the wire and reducing the risk of exposure.

[0028] The anti-drip device 6 also includes a friction column 64, a screw 65, a sliding ring 66, a U-shaped guide plate 67, a plurality of hollow arc pieces 68 and an elastic telescopic rod 69. The friction column 64 is rotatably mounted inside the drying plate 63 at one side away from the axis of the device body 1. Both ends of the screw 65 are fixedly mounted on the side of the friction column 64 close to the axis of the drying plate 63. The internal thread of the sliding ring 66 is connected to the outer wall of the screw 65. The bottom of the U-shaped guide plate 67 is slidably mounted on the bottom of the inner wall of the drying plate 63. The plurality of hollow arc pieces 68 are fixedly mounted on the outer wall of the U-shaped guide plate 67 at one side away from the screw 65. The elastic telescopic rod 69 is fixedly mounted on the inner wall of the U-shaped guide plate 67 at one side close to the screw 65. Through the above cooperation, the desiccant particles inside the drying plate 63 are gathered by relying on the U-shaped guide plate 67, and the desiccant particles are reciprocated by relying on the elastic telescopic rod 69 to ensure that the desiccant can be volatilized evenly, while improving the desiccant's absorption and drying efficiency of water vapor, ensuring that the water vapor can be quickly neutralized by the desiccant to avoid the occurrence of excessive local use of the drying plate 63.

[0029] The outer wall of the friction column 64 contacts the top of the inner wall of the device body 1, and a plurality of hollow arc pieces 68 are evenly distributed on the outer wall of the U-shaped guide plate 67. The arc surface of the hollow arc piece 68 is located on the movement trajectory of the sliding ring 66, and the telescopic end of the elastic telescopic rod 69 is fixedly installed inside the drying plate 63.

[0030] When in use, the U-shaped plate 54 moves upward and drives the transmission plate 61 to move synchronously. The transmission plate 61 is limited by the support rod 62 and pushed by the U-shaped plate 54, so that the support rod 62 is turned back to the back of the inner wall of the device body 1, so that the hinge axis between the transmission plate 61 and the drying plate 63 starts to rotate, and the drying plate 63 is caused to slide backward along the top of the inner wall of the device body 1. The drying plate 63 performs sliding friction on the top of the inner wall of the device body 1. Through the above cooperation, the heat generated by the operation of the meter 2 and the cooling caused by rain on the top of the inner wall of the device body 1 are wiped off by the drying plate 63, so as to prevent the water droplets from dripping onto the outer wall surface of the wire for a long time, causing the wire to further accelerate the oxidation speed when it is hot during operation, thereby extending the service life of the wire and reducing the risk of exposure. At the same time, the drying plate 63 drives the friction column 64 to slide along the top of the inner wall of the device body 1 to generate friction. The screw 65 starts to rotate by friction and drives the screw 65 to rotate. The screw 65 drives the threaded sliding ring 66 to slide along its outer wall through the spiral groove. When the sliding ring 66 slides, it contacts the arc surface of the hollow arc piece 68. At this time, the hollow arc piece 68 generates a force moving away from the outer wall of the screw 65 through the contact force. The hollow arc piece 68 pushes the U-shaped guide plate 67 to slide synchronously along the bottom of the inner wall of the drying plate 63. At the same time, the U-shaped guide plate 67 pushes the elastic telescopic rod 69 to move synchronously. The telescopic end of the elastic telescopic rod 69 contracts toward the inside of its fixed end through the limit of the drying plate 63. Through the above cooperation, the desiccant particles inside the drying plate 63 are gathered by relying on the U-shaped guide plate 67, and the desiccant particles are reciprocated by relying on the elastic telescopic rod 69 to ensure that the desiccant can be volatilized evenly, while improving the absorption and drying efficiency of the desiccant to water vapor, ensuring that the water vapor can be quickly neutralized by the desiccant to avoid the occurrence of excessive use of the drying plate 63.
