Description

Technical Field

[0001] This invention belongs to the technical field of electricity metering boxes, specifically relating to an outdoor waterproof electricity metering box. Background Technology

[0002] A metering box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy, including electricity meters, voltage and current transformers and their secondary circuits. It is also known as a meter box and is a widely used power distribution product in low-voltage power distribution systems for indoor and outdoor metering in urban areas.

[0003] Patent publication number CN222720950U discloses an outdoor waterproof electricity metering box, including a box body. A buffer assembly is located on the top of the box body, and a worm gear is also located on the top of the box body. The worm gear has a rotating assembly, and a threaded cylinder is fixedly connected to the bottom of the worm gear. The bottom end of the threaded cylinder passes through the top of the box body and extends into the interior of the box body. The threaded cylinder is rotatably connected to the box body. In this outdoor waterproof electricity metering box, the threaded cylinder is threadedly connected to a threaded rod, which drives a mounting plate to move upwards. The mounting plate, in turn, drives multiple U-shaped heat dissipation pipes upwards. At this point, the multiple U-shaped heat dissipation pipes move away from multiple stops. When the two cover plates contact the box body, the multiple U-shaped heat dissipation pipes also reach their positions, allowing continued heat dissipation to the interior of the box body. This structural design solves the problem of heat dissipation even when the heat dissipation windows are blocked, improving the practicality of the device.

[0004] However, this device also has shortcomings: while it achieves good heat dissipation for the cabinet through multiple U-shaped heat pipes, it is difficult to create a good ventilation environment inside the cabinet during the heat dissipation process. The cabinet is prone to condensation inside due to the temperature difference between the inside and outside on rainy days, which increases the internal humidity and interferes with electrical appliances. At the same time, during heavy rain, external moisture can easily penetrate into the cabinet through the gaps in the cabinet door. Furthermore, it is difficult to ensure that the internal wiring is always kept loose to avoid the phenomenon of many wires sticking together. Summary of the Invention

[0005] The purpose of this invention is to provide an outdoor waterproof electricity metering box to solve the problem mentioned in the background art that it is difficult to form a good ventilation environment inside the cabinet during the heat dissipation process, and the cabinet is prone to moisture generation inside due to the temperature difference between the inside and outside on rainy days.

[0006] To achieve the above objectives, this invention provides an outdoor waterproof electricity metering box, comprising: a cabinet, a mesh plate fixedly installed inside the cabinet's flow channel, a drain pipe fixedly installed through the bottom of the cabinet, two electric rotating rods symmetrically and rotatably installed at the bottom edge of the cabinet's inner wall, and a drive plate movably installed through the outer wall of the electric rotating rod's reciprocating spiral groove. Located in a factory area, the cabinet is susceptible to oxidation and damage from heavy and prolonged rain. Therefore, when rain occurs, the electric rotating rods are activated. As the electric rotating rods rotate at the bottom of the cabinet's inner wall, the non-self-locking reciprocating spiral groove on their outer wall guides the drive plate's internal locking block, causing the drive plate to reciprocate vertically along the back of the cabinet's inner wall. An anti-intrusion device is provided below the drive plate to prevent external moisture from entering the cabinet's interior. Around the anti-intrusion device are anti-sticking devices to prevent electrical wires from sticking together due to moisture. A hollow tube is fixedly installed on the front of the drive plate, with its top movably penetrating the top of the cabinet. A water-blocking plate is fixedly installed through the top of the hollow tube. A protective plate is slidably installed on the outer sidewall of the cabinet. The top of the protective plate is fixedly installed at the bottom of the baffle. A drive plate drives the hollow tube to move synchronously, and the hollow tube drives the baffle to move back and forth vertically. When the baffle rises, it causes the protective plate to slide vertically along the sidewall of the cabinet. At this time, the protective plate releases its obstruction of the ventilation slots of the cabinet, which facilitates the formation of a lateral ventilation space inside the cabinet. The mesh plate effectively prevents external dirt from entering the cabinet. A filter plate is fixedly installed inside the water inlet slot of the baffle, and a water storage tank is fixedly installed through and inside the bottom of the hollow tube. The water storage tank is equipped with several spiral hoses that are equidistantly installed inside. The baffle plate drives the filter plate to move synchronously. Under the protection of the filter plate, only rainwater enters the hollow tube through the water inlet groove at the top of the baffle plate. The rainwater inside the hollow tube enters the water storage tank and then flows downward into the spiral hoses connected to the water storage tank. Finally, it is discharged through the drain pipe. When the hollow tube drives the water storage tank to move vertically back and forth, the water storage tank will pull the spiral hoses to deform back and forth, thereby accelerating the flow speed of rainwater inside the spiral hoses.

[0007] In one possible implementation, the cabinet has flow channels at both the left and right ends, a base at the bottom of the cabinet, a mesh panel to prevent external dirt from entering when the cabinet is ventilated, a non-self-locking reciprocating spiral groove on the outer wall of the top of the electric rotating rod, and the back of the drive plate to be slidably installed on the back of the inner wall of the cabinet.

[0008] In one possible implementation, the baffle is designed with an sloping surface and has a water inlet groove at the top. The water inlet groove of the baffle is connected to the inside of the hollow tube. The protective plate is located at the flow groove of the cabinet. The filter plate effectively prevents external dirt from clogging the water inlet groove of the baffle. The bottom of the spiral hose is inserted through and fixedly installed inside the drain pipe.

[0009] In one possible implementation, the anti-intrusion device includes an L-shaped frame, the top of which is fixedly mounted on the bottom of a drive plate. A dryer is fixedly mounted inside the L-shaped frame, with the air outlet of the dryer facing the spiral hose. The dryer and the spiral hose work together to accelerate heat dissipation. When the drive plate reciprocates vertically, it drives the L-shaped frame to move synchronously. The L-shaped frame drives the dryer to reciprocate vertically. After the dryer is started, it blows air onto the spiral hose.

[0010] In one possible implementation, the anti-intrusion device further includes a circular groove frame. The bottom of the circular groove frame is slidably mounted on the bottom of the inner wall of the cabinet via a spring. The circular groove on the back of the circular groove frame is located on the movement trajectory of the L-shaped frame's arc surface. When the L-shaped frame moves vertically, it contacts and abuts against the circular groove of the circular groove frame, generating a thrust. The L-shaped frame causes the circular groove frame to slide horizontally along the bottom of the inner wall of the cabinet. Afterward, the circular groove frame returns to its original position due to the spring force. This process is repeated. A square telescopic frame is fixedly installed on the back of the circular groove frame. The square telescopic frame is elastically designed. A sealing strip is fixedly installed inside one end of the front of the cabinet. The circular groove frame drives the square telescopic frame to move synchronously. When the square telescopic frame moves forward, it contacts and abuts against the sealing strip, causing deformation. The sealing strip tightly seals the door seam on the front of the cabinet, preventing external moisture from entering the cabinet through the gaps. When the sealing strip no longer deforms, the telescopic end of the square telescopic frame is abutted and retracts. A hollow plate is fixedly installed on the back of the circular groove frame. A drying oven is fixedly installed inside the hollow plate. A connecting rod plate is provided at the air hole on the top of the drying oven.

[0011] In one possible implementation, the back of the sealing strip is located on the front movement trajectory of the telescopic end of the square telescopic frame, and the sealing strip is square in design. The bottom of the hollow plate is slidably installed on the bottom of the inner wall of the cabinet, and a friction groove is opened at the top edge of the hollow plate. The drying box contains desiccant particles, and an air hole is opened at the top of the drying box. The back of the connecting rod plate is fixedly installed on the back of the inner wall of the cabinet. At the same time, when the circular groove frame slides, it drives the drying box to move synchronously. When the drying box moves horizontally, the connecting rod plate, which is limited by the back of the inner wall of the cabinet, remains stationary. At this time, the connecting rod plate no longer blocks the air hole at the top of the drying box. The dry gas inside the drying box can be discharged and fill the interior of the cabinet. With ventilation inside the cabinet and the blowing of the air dryer, the dry gas can be quickly dispersed throughout the entire space inside the cabinet.

[0012] In one possible implementation, the anti-adhesion device includes a fixing plate, the back of which is fixedly installed on the back of the inner wall of the cabinet. A rotating wheel is rotatably installed on the side of the fixing plate away from the hollow board, and a lead screw is fixedly installed on the side of the rotating wheel away from the fixing plate. When the hollow board moves horizontally, it contacts and rubs against the circumferential surface of the rotating wheel, which is limited by the fixing plate, through a friction groove opened on its top. The rotating wheel starts to rotate due to friction, and the rotating wheel drives the lead screw to rotate. An L-shaped sliding plate is movably installed through the outer wall of the lead screw, and an absorbent cotton block is fixedly installed on the side wall of the L-shaped sliding plate.

[0013] In one possible implementation, the circumferential surface of the rotating wheel contacts the friction groove on the top of the hollow plate, the outer wall of the lead screw is a non-self-locking spiral groove, the bottom of the L-shaped sliding plate is slidably installed on the bottom of the inner wall of the cabinet, and the bottom of the absorbent cotton block contacts the bottom edge of the inner wall of the cabinet. When the lead screw rotates, it guides the internal locking block of the L-shaped sliding plate through the non-self-locking spiral groove on its outer wall. At this time, the L-shaped sliding plate slides horizontally along the inner wall of the cabinet, and the L-shaped sliding plate drives the absorbent cotton block to wipe horizontally along the bottom of the inner wall of the cabinet. The absorbent cotton block covers and absorbs the area on the bottom of the inner wall of the cabinet where moisture is likely to grow.

[0014] In one possible implementation, a slanted frame is hinged to one side wall of the back of the L-shaped sliding plate via a torsion spring. An abutment frame is hinged to the end of the slanted frame away from the L-shaped sliding plate. When the L-shaped sliding plate slides horizontally, it drives the slanted frame to move synchronously. The slanted frame is limited by the abutment frame, at which point the hinge axis of the slanted frame begins to rotate, and the slanted frame moves in an arc-shaped trajectory. The slanted frame pushes the abutment frame forward. A humidity detector is installed inside the abutment frame, which detects the surface humidity of the wire. The abutment frame drives the humidity detector to move synchronously, pushing the wire forward to prevent the wires from sticking together due to moisture. Simultaneously, the humidity detector detects the surface humidity of the wire and transmits the detection data to the operator to ensure the wire humidity is within a safe range.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by cooperating with the electric rotating rod, drive plate, hollow tube, water baffle, protective plate, filter plate, water tank and spiral hose, the water baffle, driven by the electric rotating rod, not only provides static rain protection but also increases dynamic movement. Its inclined design guides rainwater, enhancing the waterproof protection of the cabinet, extending its service life, and creating a good ventilation environment for the cabinet in humid weather to ensure internal cooling and drying. The reciprocating spiral hose prevents rainwater from accumulating or remaining inside. Simultaneously, as rainwater flows inside the spiral hose, it quickly removes heat from the cabinet, and in conjunction with the opened protective plate, accelerates the cooling speed inside the cabinet, preventing moisture buildup due to temperature differences between the inside and outside, and improving the protection of internal electrical components and wiring.

[0016] By incorporating an anti-intrusion device, and through the coordinated use of a drive plate, L-shaped frame, air dryer, round groove frame, square telescopic frame, sealing strip, hollow plate, drying chamber, and connecting rod plate, the L-shaped frame expands the air dryer's blowing range, accelerating the airflow speed inside the cabinet while simultaneously cooling the outside of the spiral hose. This prevents the spiral hose from aging and breaking due to prolonged temperature differences between the inside and outside. The round groove frame effectively fills the gaps in the cabinet door, preventing external moisture from intruding and corroding the electrical appliances and wires inside the cabinet. At the same time, the drying gas inside the drying chamber further enhances the dryness inside the cabinet, strengthening the waterproofing and protection of the precision components inside the cabinet, building upon the existing ventilation and cooling.

[0017] By employing an anti-adhesion device, a drying chamber, a fixed plate, a rotating wheel, a lead screw, an L-shaped sliding plate, absorbent cotton pads, a slanted frame, a contact frame, and a humidity detector are used. Wiping with absorbent cotton pads prevents moisture from lingering in the corners and edges of the cabinet, and avoids moisture adhering to the surface of the wires inside the cabinet. This reduces the insulation resistance between the wires and the surrounding medium, preventing excessive current loss in case of circuit leakage. The reciprocating movement of the contact frame loosens the numerous wires, allowing moisture on the wire surfaces to dry quickly during ventilation inside the cabinet and the desiccant's evaporation phase. This prevents moisture from affecting the accuracy of meter readings and also prevents short circuits caused by wires sticking together, which could lead to arcing and breakdown of surrounding circuits.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-8 As shown, one embodiment of the present invention is: an outdoor waterproof electricity metering box, comprising: a cabinet 1, a mesh plate 3 fixedly installed inside the flow channel of the cabinet 1, a drain pipe 4 fixedly installed through the bottom of the cabinet 1, two electric rotating rods 5 symmetrically and rotatably installed at the bottom edge of the inner wall of the cabinet 1, a drive plate 6 movably installed through the outer wall of the reciprocating spiral groove of the electric rotating rod 5, and an anti-intrusion device 13 provided below the drive plate 6 to prevent external moisture from entering the interior of the cabinet 1, and a retaining device 13 provided around the anti-intrusion device 13 to prevent the wires from getting wet. The device 14 prevents air from sticking together. A hollow tube 7 is fixedly installed on the front of the drive plate 6. The top of the hollow tube 7 moves through the inside of the top of the cabinet 1. A baffle plate 8 is fixedly installed through the top of the hollow tube 7. A protective plate 9 is slidably installed on the outer side wall of the cabinet 1. The top of the protective plate 9 is fixedly installed at the bottom of the baffle plate 8. A filter plate 10 is fixedly installed inside the water inlet groove of the baffle plate 8. A water storage tank 11 is fixedly installed through the bottom of the hollow tube 7. Several spiral hoses 12 are fixedly installed through the water storage tank 11 at equal intervals.

[0022] Both ends of the cabinet 1 are provided with flow channels. The bottom of the cabinet 1 is provided with a base 2. The mesh plate 3 prevents external dirt from entering when the cabinet 1 is ventilated. The top of the electric rotating rod 5 is provided with a non-self-locking reciprocating spiral groove. The back of the drive plate 6 is slidably installed on the back of the inner wall of the cabinet 1.

[0023] The baffle plate 8 is designed with a slope and has a water inlet groove at the top. The water inlet groove of the baffle plate 8 is connected to the inside of the hollow tube 7. The protective plate 9 is located at the flow groove of the cabinet 1. The filter plate 10 effectively prevents external dirt from clogging the water inlet groove of the baffle plate 8. The bottom of the spiral hose 12 is inserted through and fixedly installed inside the drain pipe 4.

[0024] Driven by the electric rotating rod 5, the water baffle 8 not only provides static rain protection but also increases dynamic movement. Its inclined design guides rainwater, enhancing the waterproof protection of the cabinet 1, extending its service life, and creating a good ventilation environment for the cabinet 1 in humid weather to ensure internal cooling and dryness. The reciprocating spiral hose 12 prevents rainwater from accumulating or remaining inside. As rainwater flows through the spiral hose 12, it quickly removes heat from the inside of the cabinet 1. Combined with the opened protective plate 9, this accelerates the cooling speed inside the cabinet 1, preventing moisture buildup due to temperature differences between the inside and outside, and improving the protection of the electrical appliances and wiring inside the cabinet 1.

[0025] During use, cabinet 1, located in the factory area, is prone to oxidation and damage if subjected to heavy and prolonged rain. Therefore, when rain occurs, the electric rotating rod 5 is activated. As the electric rotating rod 5 rotates at the bottom of the inner wall of cabinet 1, it guides the internal locking block of the drive plate 6 through the non-self-locking reciprocating spiral groove on its outer wall. This causes the drive plate 6 to reciprocate vertically along the back of the inner wall of cabinet 1. The drive plate 6 drives the hollow tube 7 to move synchronously, and the hollow tube 7 drives the water baffle 8 to reciprocate vertically. When the water baffle 8 rises, it causes the protective plate 9 to slide vertically along the side wall of cabinet 1. At this time, the protective plate 9 removes its obstruction of the ventilation slot of cabinet 1, facilitating the movement of the cabinet. The interior of the cabinet 1 is designed to be ventilated from both sides, and the mesh panel 3 effectively prevents external dirt from entering the interior of the cabinet 1. The baffle plate 8 drives the filter plate 10 to move synchronously. Under the protection of the filter plate 10, only rainwater enters the hollow tube 7 through the water inlet groove at the top of the baffle plate 8. The rainwater inside the hollow tube 7 enters the water storage tank 11. Then, the rainwater enters the spiral hose 12 connected to the water storage tank 11 and flows downward. After that, it is discharged through the drain pipe 4. When the hollow tube 7 drives the water storage tank 11 to move back and forth vertically, the water storage tank 11 will pull the spiral hose 12 to deform back and forth, thereby accelerating the flow speed of rainwater inside the spiral hose 12.

[0026] According to the above embodiment, the electric rotating rod 5 drives the baffle 8 to increase dynamic movement while statically providing rain protection. Its inclined design guides rainwater, enhancing the waterproof protection of the cabinet 1, extending its service life, and creating a good ventilation environment for the cabinet 1 in humid weather to ensure internal cooling and dryness. The reciprocating spiral hose 12 prevents rainwater from accumulating or remaining inside. Simultaneously, as rainwater flows through the spiral hose 12, it quickly removes heat from the cabinet 1. Combined with the opened protective plate 9, this accelerates the cooling speed of the cabinet 1, preventing moisture buildup due to temperature differences and improving the protection of the internal electrical components and wiring.

[0027] like Figures 1-8 As shown, based on the above embodiments, another embodiment of the present invention further includes an anti-intrusion device 13; The anti-intrusion device 13 includes an L-shaped frame 131. The top of the L-shaped frame 131 is fixedly installed at the bottom of the drive plate 6. A dryer 132 is fixedly installed inside the L-shaped frame 131. The air outlet of the dryer 132 is directly facing the spiral hose 12, and the dryer 132 and the spiral hose 12 cooperate to accelerate the heat dissipation.

[0028] The anti-intrusion device 13 also includes a circular groove frame 133. The bottom of the circular groove frame 133 is slidably installed on the bottom of the inner wall of the cabinet 1 by a spring. The circular groove on the back of the circular groove frame 133 is located on the arc movement trajectory of the L-shaped frame 131. A square telescopic frame 134 is fixedly installed on the back of the circular groove frame 133. The square telescopic frame 134 is elastically designed. A sealing strip 135 is fixedly installed inside one end of the front of the cabinet 1. A hollow plate 136 is fixedly installed on the back of the circular groove frame 133. A drying oven 137 is fixedly installed inside the hollow plate 136. A connecting rod plate 138 is provided at the air hole on the top of the drying oven 137.

[0029] The back of the sealing strip 135 is located on the front movement trajectory of the telescopic end of the square telescopic frame 134, and the sealing strip 135 is square. The bottom of the hollow plate 136 is slidably installed on the bottom of the inner wall of the cabinet 1, and a friction groove is opened at the top edge of the hollow plate 136. The drying box 137 contains desiccant particles, and an air hole is opened at the top of the drying box 137. The back of the connecting rod plate 138 is fixedly installed on the back of the inner wall of the cabinet 1.

[0030] The L-shaped frame 131 expands the blowing range of the air dryer 132, accelerating the air circulation speed inside the cabinet 1 while cooling the outside of the spiral hose 12, preventing the spiral hose 12 from aging and breaking due to the long-term temperature difference between the inside and outside. The push of the circular groove frame 133 effectively fills the gaps in the door of the cabinet 1, preventing external moisture from entering and corroding the electrical appliances and wires inside the cabinet 1. At the same time, with the help of the dry gas inside the drying box 137, the dryness inside the cabinet 1 is further improved on the basis of the original ventilation and cooling, strengthening the waterproofing and protection of the precision components inside the cabinet 1.

[0031] In use, the reciprocating vertical motion of the drive plate 6 drives the L-shaped frame 131 to move synchronously. The L-shaped frame 131 drives the air dryer 132 to move reciprocating vertically. After the air dryer 132 is started, it blows the spiral hose 12. When the L-shaped frame 131 moves vertically, it contacts and abuts the groove of the circular groove frame 133, generating a thrust. The L-shaped frame 131 causes the circular groove frame 133 to slide horizontally along the bottom of the inner wall of the cabinet 1. Then, the circular groove frame 133 returns to its original position due to the spring force. This process is repeated. The circular groove frame 133 drives the square telescopic frame 134 to move synchronously. When the square telescopic frame 134 moves forward, it contacts and abuts the sealing strip 135, causing deformation. The sealing strip 135 acts on the cabinet 1. The front door seam is tightly sealed to prevent external moisture from entering the cabinet 1 through the gap. When the sealing strip 135 no longer deforms, the telescopic end of the square telescopic frame 134 is resisted and retracts. At the same time, when the round groove frame 133 slides, it drives the drying box 137 to move synchronously. When the drying box 137 moves horizontally, the connecting rod plate 138, which is limited by the back of the inner wall of the cabinet 1, remains stationary. At this time, the connecting rod plate 138 no longer blocks the air hole at the top of the drying box 137. The dry gas inside the drying box 137 can be discharged and fill the interior of the cabinet 1. With ventilation inside the cabinet 1 and the blowing of the air dryer 132, the dry gas can be quickly dispersed throughout the entire space inside the cabinet 1.

[0032] According to the above embodiments, the L-shaped frame 131 expands the blowing range of the air dryer 132, accelerates the air circulation speed inside the cabinet 1, and cools the outside of the spiral hose 12, preventing the spiral hose 12 from aging and breaking due to the long-term temperature difference between the inside and outside. The push of the circular groove frame 133 effectively fills the gaps in the door of the cabinet 1, preventing external moisture from entering and corroding the electrical appliances and wires inside the cabinet 1. At the same time, with the help of the dry gas inside the drying box 137, the dryness inside the cabinet 1 is further improved on the basis of the original ventilation and cooling, and the waterproofing and protection of the precision components inside the cabinet 1 are strengthened.

[0033] like Figures 1-8 As shown, based on the above embodiments, another embodiment of the present invention further includes an anti-adhesion device 14; The anti-adhesion device 14 includes a fixing plate 141. The back of the fixing plate 141 is fixedly installed on the back of the inner wall of the cabinet 1. A rotating wheel 142 is rotatably installed on the side of the fixing plate 141 away from the hollow board 136. A lead screw 143 is fixedly installed on the side of the rotating wheel 142 away from the fixing plate 141. An L-shaped sliding plate 144 is movably installed through the outer wall of the lead screw 143. A water-absorbing cotton block 145 is fixedly installed on the side wall of the L-shaped sliding plate 144.

[0034] The circumferential surface of the rotating wheel 142 contacts the friction groove on the top of the hollow plate 136, the outer wall of the lead screw 143 is a non-self-locking spiral groove, the bottom of the L-shaped slide plate 144 is slidably installed on the bottom of the inner wall of the cabinet 1, and the bottom of the absorbent cotton block 145 contacts the bottom edge of the inner wall of the cabinet 1.

[0035] A slanted frame 146 is hinged to one side wall of the back of the L-shaped slide plate 144 via a torsion spring. An abutment frame 147 is hinged to the end of the slanted frame 146 away from the L-shaped slide plate 144. A humidity detector 148 is installed inside the abutment frame 147 to detect the humidity of the wire surface.

[0036] Wiping with absorbent cotton pads 145 prevents moisture from lingering in the corners and edges of the cabinet 1, and prevents moisture from adhering to the surface of the wires inside the cabinet 1, thereby reducing the insulation resistance between the wire surface and the surrounding medium and preventing large current from being generated when the circuit leaks, thus increasing losses. The reciprocating push of the contact frame 147 loosens the numerous wires, allowing the moisture on the surface of the wires to be ventilated inside the cabinet 1 and quickly dried during the desiccant gas evaporation stage, preventing moisture from affecting the accuracy of the meter readings, and also preventing the arc from breaking down the surrounding circuits when a short circuit occurs in a single wire due to the wires sticking together.

[0037] In use, when the hollow plate 136 moves horizontally, it contacts and rubs against the circumferential surface of the rotating wheel 142, which is limited by the fixed plate 141, through the friction groove on its top. The rotating wheel 142 starts to rotate due to friction, which drives the lead screw 143 to rotate. When the lead screw 143 rotates, it guides the internal locking block of the L-shaped slide plate 144 through the non-self-locking spiral groove on its outer wall. At this time, the L-shaped slide plate 144 slides horizontally along the inner wall of the cabinet 1. The L-shaped slide plate 144 drives the water-absorbing cotton block 145 to wipe the bottom of the inner wall of the cabinet 1 horizontally. The water-absorbing cotton block 145 covers the area on the bottom of the inner wall of the cabinet 1 where moisture is likely to grow. Covering and absorbing; When the L-shaped sliding plate 144 slides horizontally, it drives the inclined frame 146 to move synchronously. The inclined frame 146 is limited by the abutment frame 147. At this time, the hinge shaft of the inclined frame 146 begins to rotate, and the inclined frame 146 moves in an arc trajectory. The inclined frame 146 pushes the abutment frame 147 forward. The abutment frame 147 drives the humidity detector 148 to move synchronously. At this time, the abutment frame 147 pushes the wire forward to prevent the wires from sticking together due to moisture. At the same time, the humidity detector 148 detects the humidity on the surface of the wire and transmits the detection data to the information system so that the staff can understand whether the humidity of the wire is within the safe range.

[0038] According to the above embodiment, by wiping with the absorbent cotton block 145, moisture is prevented from remaining in the corners of the cabinet 1 for a long time, and moisture is prevented from adhering to the surface of the wires inside the cabinet 1, thereby reducing the insulation resistance between the wire surface and the surrounding medium and preventing the generation of a large current when the circuit leaks, thus increasing the loss; by the reciprocating push of the contact frame 147, the numerous wires are loosened, so that the moisture on the surface of the wires can be ventilated inside the cabinet 1 and quickly dried during the desiccant gas evaporation stage, avoiding the impact of moisture on the accuracy of the meter reading data, and at the same time preventing the arc from breaking down the surrounding circuits when a short circuit occurs in a single wire due to the wires sticking together.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
