Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, in particular to a meter-inlet wiring device for 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 type of electric meter often requires a corresponding meter box to cooperate with it. At the same time, a mounting plate is usually required next to the electric meter to install the incoming and outgoing line switches, and to arrange the incoming and outgoing wiring of the electric meter.

[0003] Patent publication number CN205210151U discloses an inlet wiring device for an electricity meter box, comprising an electricity meter, a mounting plate, a guide groove, inlet wiring, a wire crimping device, outlet wiring, a clamping slot, an on-off switch, wiring terminals, an inlet switch connector, fixing holes, a reinforcement plate, and an outlet switch connector. The electricity meter is mounted on the upper portion of the mounting plate via the guide groove; the inlet wiring or outlet wiring is connected to the on-off switch via the wire crimping device; the on-off switch is mounted in the middle of the mounting plate via the clamping slot; the wiring terminals are connected to the on-off switch via the inlet switch connector; and the fixing holes are provided on the reinforcement plate. The provision of the patented guide groove, outlet wiring, and wire crimping device facilitates adjustment of the installation structure, improves installation efficiency, ensures safety and reliability, and facilitates market promotion and application.

[0004] However, the device still has some shortcomings: it 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 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: a meter-in wiring device for an electric power meter box, comprising a device body, wherein square grooves are provided on the left and right sides of the device body, a wire entry hole is provided at the bottom of the device body, a safety door is provided on the front of the device body, a meter is provided inside the device body, a power component is provided at the bottom of the meter, and a mounting component is provided at the bottom of the power component;

[0007] An anti-falling device is provided inside the device body, an anti-penetration device is provided on the periphery of the anti-falling device, and an anti-drip device is provided above the anti-penetration device;

[0008] The anti-falling device includes a circular frame, the bottom of the circular frame is fixedly installed 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 installed on the top of the telescopic end of the elastic telescopic plate, and the limiting arc plate is located between the wire inlet hole of the device body and the mounting assembly, two dehumidification components are fixedly installed on the bottom of the inner wall of the device body, and the dehumidification component 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 above 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 limiting arc plate guides the wire vertically, and the wire pulls the limiting arc plate upward through the resistance force, and the limiting arc plate pulls the elastic expansion plate to move synchronously. The elastic expansion 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 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 limiting arc plate, the limiting arc plate causes the hinge axis of the elastic expansion 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 restricts 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. The sealing plate opens the cover to the inside of the device body, and then the sealing plate is reset by the torsion spring.

[0009] 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.

[0010] According to the above technical solution, the anti-infiltration device includes a contact plate, a vertical plate and several 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 conflicts with 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 interference during the movement of the contact plate. After 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 is caused to vibrate through the transmission of force.

[0011] The U-shaped plate is fixed on the bottom of the resistance plate at one end near the back of the device body, and the bottom of the wave plate is fixed on the bottom of the inner wall of the U-shaped plate. The ends of the wave plates are rotatably mounted on the outer wall of the U-shaped plate near the axis of the device body, and the extrusion wheel is fixed on the outer wall of the rotation rod near 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, and the rotating rod drives the extrusion wheel to slide 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. As a result, the extrusion wheel starts to rotate through friction.

[0012] According to the above technical solution, the U-shaped plate is located outside the dehumidification component, and several rotating rods are evenly distributed on the outer wall of the U-shaped plate. The outer wall of the extrusion wheel contacts the edge of one side of the back of the safety door.

[0013] The cam is hinged on the top of the U-shaped plate and is fixed on the inner wall of the device body, so that the cam can slide back and forth along the top of the U-shaped plate.

[0014] 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 mounted on the inside of the drying plate away from the axis of the device body. Both ends of the screw are fixedly mounted 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. The bottom of the U-shaped guide plate is slidably mounted 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 mounted on the outer wall of the U-shaped guide plate. The elastic telescopic rod is fixedly mounted on the side close to the screw. 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 force 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 resists the arc surface of the hollow arc piece. At this time, the hollow arc piece generates a force to move away from the outer wall of the screw rod 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 retracts toward the inside of its fixed end through the limit of the drying plate.

[0015] According to the above technical solution, the outer wall of the friction column contacts the top of the inner wall of the device body, several 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.

[0016] The present invention provides a wiring device for an electric power meter box. It has the following beneficial effects:

[0017] (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 limiting 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 limiting arc plate and the elastic expansion plate adaptively stabilize wires of different thicknesses, thereby reducing the risk of the wires falling off after being disturbed by external forces after being fixed inside the installation component; at the same time, the sealing plate changes the sealing environment inside the device body, facilitating the dehumidification component to quickly discharge moisture from the device body, preventing the device body from being eroded by acid rain when it is backed against the wall, resulting in excessive moisture inside the body, thereby eroding the surface of the wire and the exposed part of the wire, and increasing the risk of short circuit between the line and the meter.

[0018] (2) The present invention sets up 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 according to the range of change of the power transmission curve, so as to avoid abnormal measurement of the meter caused by increased resistance; and the wave plate is used to accelerate the circulation speed of the air around the dehumidification component, effectively improve the dehumidification effect, and avoid moisture falling and settling at 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 safety door due to aging of the sealing strip, which causes rainwater to penetrate into the inside of the device body.

[0019] (3) The present invention adopts the setting of the anti-drip device, and cooperates with the U-shaped plate, transmission plate, support rod, drying plate, friction column, screw, sliding ring, U-shaped guide plate, hollow arc plate and elastic telescopic rod. The drying plate wipes off the heat generated by the meter during operation and the cooling caused by rain, which atomizes and condenses into water droplets 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 rate 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, ensuring that the desiccant can evaporate evenly while improving the desiccant's absorption and drying efficiency of the water vapor, ensuring that the water vapor can be quickly neutralized by the desiccant to avoid the occurrence of local excessive use of the drying plate.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figures 1-8 One embodiment of the present invention is: a meter-in wiring device for an electric power meter box, comprising a device body 1, wherein square grooves are provided on the left and right sides of the device body 1, a wire entry hole is provided at the bottom of the device body 1, a safety door 11 is provided on the front of the device body 1, a meter 2 is provided inside the device body 1, a power component 3 is provided at the bottom of the meter 2, and a mounting component 31 is provided at the bottom of the power component 3;

[0031] An anti-falling device 4 is provided inside the device body 1, an anti-penetration device 5 is provided on the periphery of the anti-falling device 4, and an anti-drip device 6 is provided above the anti-penetration device 5;

[0032] The anti-falling device 4 includes a circular frame 41, the bottom of the circular frame 41 is fixedly mounted on the bottom of the inner wall of the device body 1, and a plurality of support plates 42 are arranged inside the circular frame 41. The plurality of support plates 42 are symmetrically and fixedly distributed inside the circular frame 41, and 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, and a limiting arc plate 44 is fixedly mounted on the top of the telescopic end of the elastic telescopic plate 43. The limiting arc plate 44 is located between the wire inlet hole of the device body 1 and the mounting assembly 31. Two dehumidification assemblies 45 are fixedly mounted on the bottom of the inner wall of the device body 1, and the dehumidification assembly 45 is located on the front of the circular frame 41. Two electric reciprocating screws 46 are rotatably mounted 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 mounted with sliding plates 47. The sliding plate 47 is slidably mounted on the dehumidification assembly 4 near the side of the axis of the device body 1 5. A round rod 48 is fixedly installed on the inner wall of the square groove of the device body 1. The outer wall of the round rod 48 is hinged with a sealing plate 49 through a torsion spring. A T-shaped arc block 410 is fixedly installed on the sealing plate 49 near the axis of the device body 1. The above cooperation ensures the accurate wiring of the meter 2, reduces the number of times the wires are bumped, and improves the wiring efficiency. At the same time, the limiting arc plate 44 and the elastic expansion plate 43 adaptively stabilize 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, preventing 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.

[0033] 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 on the side close to the axis of the device body 1 .

[0034] 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 elastic expansion plate 43 to move synchronously. The elastic expansion 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 power component 3 is inside, the staff fixes the wires through the installation component 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 component 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 fixed to stabilize wires of different thicknesses, thereby reducing the difficulty of fixing the wires in the installation component. 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 the outer wall of the electric reciprocating screw 46 restricts 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 interior of the device body 1. Thereafter, the sealing plate 49 is reset by the torsion spring. Through the above cooperation, the sealing plate 49 changes the sealing environment inside the device body 1, making it easier for the dehumidification component 45 to quickly discharge the moisture inside the device body 1, preventing the device body 1 from being corroded by acid rain when it is backed against the wall, resulting in excessive moisture inside the device body, 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.

[0035] See also Figures 1-8 , based on the above embodiment, another embodiment of the present invention further includes an anti-permeation device 5;

[0036] The anti-infiltration device 5 includes a contact plate 51, a vertical plate 52 and several tough plates 53. The contact plate 51 is fixedly installed 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 installed on the outer wall of the circular frame 41 close to the axis of the device body 1. Several tough plates 53 are equidistant from the back of the inner wall of the device body 1 and fixedly installed on the front of the vertical plate 52. The tough plates 53 are located on the movement trajectory of the contact plate 51. Through the above cooperation, the circular frame 41 is prompted to generate and vibrate the limiting arc plate 44 through vibration force, and the limiting arc plate 44 prompts 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, and 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.

[0037] 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 is fixedly installed on the bottom of the resistance plate 51 near the back of the device body 1. The bottom of the wave plate 55 is fixedly installed on the bottom of the inner wall of the U-shaped plate 54. The ends of the plurality of rotating rods 56 near 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 near 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, reducing the wear of the sealing strip while avoiding the sealing effect of the safety door 11 due to aging, which causes rainwater to penetrate into the interior of the device body 1.

[0038] The U-shaped plate 54 is located outside the dehumidification component 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 of the safety door 11 .

[0039] When in use, the sliding plate 47 drives the contact plate 51 to move synchronously when it moves upward, and the circular frame 41 limits the vertical plate 52 to keep it stationary. 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 interference 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, and the vibration of the circular frame 41 is caused by the transmission of force. Through the above cooperation, the circular frame 41 is caused to 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, and the staff judges 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 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, and the wave plate 55 moves upward and resets in the process to disturb the air around the dehumidification component 45 through its own wave surface. 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 safety door 11 due to aging, which causes rainwater to penetrate into the interior of the device body 1.

[0040] See also Figures 1-8 , based on the above embodiment, another embodiment of the present invention further includes an anti-drip device 6;

[0041] 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 passes through 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 slidingly connected to the inner wall of the device body 1. The drying plate 63 is hollow in design, and a desiccant is provided inside the drying plate 63. Through the above cooperation, the drying plate 63 is used to wipe off the heat generated by the meter 2 during operation and the cooling caused by rainwater on the top of the inner wall of the device body 1, thereby atomizing and condensing into water droplets, thereby preventing water droplets from dripping onto the outer wall surface of the wire for a long time, causing the wire to further accelerate the oxidation rate when it is hot during operation, thereby extending the service life of the wire and reducing the risk of exposure.

[0042] The anti-drip device 6 also includes a friction column 64, a screw rod 65, a sliding ring 66, a U-shaped guide plate 67, several hollow arc pieces 68 and an elastic telescopic rod 69. The friction column 64 is rotatably mounted inside the drying plate 63 on the side away from the axis of the device body 1. Both ends of the screw rod 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 rod 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. Several hollow arc pieces 68 are fixedly mounted on the outer wall of the U-shaped guide plate 67 away from the screw rod 65. The elastic telescopic rod 69 is fixedly mounted on the inner wall of the U-shaped guide plate 67 near the screw rod 65. Through the above cooperation, the U-shaped guide plate 67 is used to gather the desiccant particles inside the drying plate 63, and the elastic telescopic rod 69 is used to reciprocate and stir the desiccant particles, thereby ensuring that the desiccant can evaporate evenly and improving the desiccant's absorption and drying efficiency of water vapor, ensuring that water vapor can be quickly neutralized by the desiccant to avoid local excessive use of the drying plate 63.

[0043] The outer wall of the friction column 64 contacts the top of the inner wall of the device body 1, and a number 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.

[0044] When in use, the U-shaped plate 54 drives the transmission plate 61 to move synchronously when it moves upward. The transmission plate 61 is limited by the support rod 62 and pushed by the U-shaped plate 54, prompting the support rod 62 to flip back toward 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 prompts the drying plate 63 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, 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. 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 due to friction and drives the screw 65 to rotate. The screw 65 drives the threaded sliding ring 66 to slide along its own 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 to move away from the outer wall of the screw 65 through the resistance 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 is retracted 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 the U-shaped guide plate 67, and the desiccant particles are stirred back and forth by the elastic telescopic rod 69, so as to ensure that the desiccant can be evenly volatilized, improve the desiccant's absorption and drying efficiency of the water vapor, ensure that the water vapor can be quickly neutralized by the desiccant, and avoid the occurrence of local overuse of the drying plate 63.
