Description

Technical Field

[0001] The invention relates to the technical field of metering boxes, and in particular to a metering box with a moisture-proof function. Background Art

[0002] In the prior art, the meter box is a closed box specially used to install and protect electric energy metering equipment (such as electric energy meters, mutual inductors, etc.). It is an important part of the power system. It not only provides a safe operating environment for the metering equipment, but also effectively prevents external factors (such as dust, moisture, external force impact, etc.) from causing direct damage to the metering equipment, thereby ensuring the accuracy of power metering and the safety of the system. However, during the use of the existing meter box, in order to help the internal electric energy metering equipment to effectively dissipate heat, a number of ventilation hole structures are usually opened on both sides of the meter box. Although these ventilation holes help to dissipate heat, they also provide a channel for external moisture to enter the interior of the box. Especially in an environment with high humidity, moisture is more likely to enter the meter box through the ventilation holes. In addition, the meter box is also prone to poor sealing or inadequate waterproofing during installation, which can also cause moisture inside the box. The existing meter box does not take corresponding measures to deal with this situation, resulting in long-term moisture retention inside the box. The moisture and corrosive substances in the moisture will corrode the electrical components in the meter box, causing the component performance to decline or fail, affecting the accuracy of the measurement, and reducing the insulation performance of the electrical equipment inside the meter box, thereby increasing the risk of electric shock and short circuit.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) Through the coordinated use of the drainage control mechanism and the uniform feeding mechanism, the calcium chloride particles placed on the placement plate can absorb and combine the moisture inside the metering box during use to form hydrates, which are accumulated in a short period of time and discharged in time through the dehumidification rack and the U-shaped water pipe, thereby effectively removing the moisture inside the box, maintaining a dry environment inside the box, and preventing the long-term retention of moisture inside the box from causing corrosion to the electrical components inside the metering box, thereby improving the performance of the components, ensuring the normal operation of the metering equipment, improving the accuracy of the measurement, and improving the insulation performance of the electrical equipment inside the metering box, thereby reducing the risk of electric shock and short circuit, and ensuring the safe operation of the power system.

[0016] (2) By setting up the drainage control mechanism, the weight of the calcium chloride particles placed on the placement plate is used to exert a gravitational force on the placement plate, and in combination with the elastic effect of the first reset spring, the use of the calcium chloride particles on the placement plate can be monitored in real time. After the calcium chloride particles are used up to form hydrates, the drainage process can be automatically sensed and started to discharge the formed hydrates from the inside of the dehumidification rack, thereby eliminating the need for manual intervention, regular inspections or manual drainage, reducing dependence on operators, and thus improving the degree of automation of the equipment. In addition, by monitoring the use of the calcium chloride particles in real time, the continuity of the dehumidification process can be ensured, and the retention time of hydrates in the dehumidification rack can be reduced, thereby avoiding a decrease in dehumidification efficiency due to the exhaustion of particles and failure to replace them in time; Among them, the design of the guide plate and U-shaped water pipe can guide the hydrate to flow quickly and concentratedly to the drain outlet, reducing the diffusion and residence time of the hydrate inside the dehumidification rack. In addition, since the upper surface of the guide plate is set as an inclined surface, it can provide a natural flow path for the hydrate, reducing the resistance to the hydrate flow, thereby improving the drainage effect.

[0017] (3) By setting up a uniform feeding mechanism, the slider moves upward to touch the switch, which can synchronously drive the reciprocating screw to rotate, drive the material-dispensing barrel to move horizontally above the dehumidification rack, and cooperate with the meshing connection between the gear and the toothed plate to make the material-dispensing plate arranged in an annular shape and equidistant on the outer surface of the linkage shaft rotate inside the material-dispensing barrel, and the calcium chloride particles in the storage bin are dispensed in batches, thereby intervening in the discharge action of the calcium chloride particles, so that the calcium chloride particles can be discharged one by one, avoiding the situation where the material is discharged too much and too fast and causes congestion, and at the same time, the discharge amount of the calcium chloride particles can be effectively controlled; Among them, the flow-aiding plate arranged below the material-dispensing cylinder, in combination with its inclined characteristics, can provide a guiding path for the outflow of the material, so that the calcium chloride particles can slide out from the upper surface of the flow-aiding plate and slowly fall onto the placement plate, thereby slowing down the feeding speed of the calcium chloride particles, avoiding the situation where the calcium chloride particles collide and splash due to the feeding speed being too fast, thereby maintaining the cleanliness of the internal environment of the box. At the same time, by slowing down the feeding speed of the calcium chloride particles, it can also be avoided that the feeding speed is too fast, causing the placement plate to be subjected to a sudden impact, thereby damaging the first return spring and affecting its return effect.

[0024] Embodiment 2 of the present invention: Please refer to Figures 1 to 8 As shown, the uniform feeding mechanism 4 also includes a side plate 401 fixedly connected to the inner bottom wall of the box body 1, and the side plate 401 is arranged on the right side of the dehumidification frame 301, and a U-shaped mounting frame 402 is symmetrically fixedly connected between the side plate 401 and the left inner wall of the box body 1, and a reciprocating screw rod 403 is rotatably connected to one of the U-shaped mounting frames 402, and the reciprocating screw rod 403 is fixedly connected to the output end of the external driving source, and a sliding rod 404 is fixedly connected to the other U-shaped mounting frame 402; The outer surfaces of the sliding rod 404 and the reciprocating screw rod 403 are both provided with a linkage block 405, and the sliding rod 404 is slidably connected with the linkage block 405, and the reciprocating screw rod 403 is threadedly connected with the linkage block 405; A material-dispensing cylinder 406 is fixedly connected between the linkage blocks 405, a material storage bin 407 is fixedly connected to the top of the material-dispensing cylinder 406, a top cover plate 415 is clamped on the top of the material storage bin 407, a linkage shaft 408 is rotatably connected to the material-dispensing cylinder 406, a material-dispensing plate 409 is arranged in the material-dispensing cylinder 406, and the material-dispensing plate 409 is annularly and equidistantly fixedly connected to the outer surface of the linkage shaft 408; Gears 410 are fixedly connected to the outer surfaces of both ends of the linkage shaft 408, and a toothed plate 411 is fixedly connected to the U-shaped mounting frame 402, and the toothed plate 411 is meshedly connected with the gears 410; A flow-aiding plate 412 is also fixedly connected between the linkage blocks 405, and the flow-aiding plate 412 is arranged below the material-dispensing cylinder 406.

[0025] Please refer to Figure 2 , Figure 7 as well as Figure 8 , better: the end of the reciprocating screw 403 facing the side plate 401 is fixedly connected to the output end of the external driving source, and the driving source is set as a driving motor, and the driving motor is fixedly set at the upper end of the right side of the side plate 401, and the driving motor is electrically connected to the switch 306 mentioned above. After the calcium chloride particles placed on the placement plate 302 are used up and hydrates are formed, the gravity effect on the placement plate 302 disappears, and the elastic force of the first return spring 305 can drive the slider 303 to cooperate with the placement plate 302 to slide upward synchronously inside the dehumidification rack 301, and finally make the slider 303 touch the switch 306 to start the driving motor to start running, and synchronously make the reciprocating screw 403 able to rotate on one of the U-shaped mounting frames 402.

[0026] The effects achieved by this embodiment are as follows: compared with the prior art, by setting the uniform feeding mechanism 4, the slider 303 moves upward to touch the switch 306, so that the reciprocating screw rod 403 can be synchronously driven to rotate, and the material-dispensing barrel 406 is driven to move horizontally above the dehumidification rack 301, and the meshing connection between the gear 410 and the toothed plate 411 can be coordinated, so that the material-dispensing plate 409 arranged in an annular shape and equidistantly on the outer surface of the linkage shaft 408 can be rotated inside the material-dispensing barrel 406, and the calcium chloride particles in the storage bin 407 are dispensed in batches, thereby intervening in the feeding action of the calcium chloride particle material, so that the calcium chloride particle material can be discharged one by one, avoiding the situation that the material is discharged too much and too fast and causes congestion, and at the same time, the feeding amount of the calcium chloride particles can be effectively controlled; The flow-aiding plate 412 provided below the material-dispensing cylinder 406 can provide a guiding path for the outflow of the material by cooperating with its inclined characteristics, so that the calcium chloride particles can slide out from the upper surface of the flow-aiding plate 412 and slowly fall onto the placement plate 302, thereby slowing down the feeding speed of the calcium chloride particles, avoiding the situation where the calcium chloride particles collide and splash due to the excessive feeding speed, thereby maintaining the cleanliness of the internal environment of the box 1. At the same time, by slowing down the feeding speed of the calcium chloride particles, it is also possible to avoid the situation where the placement plate 302 is suddenly impacted due to the excessive feeding speed, thereby damaging the first return spring 305 and affecting its return effect; Finally, through the coordinated use of the drainage control mechanism 3 and the uniform feeding mechanism 4, the calcium chloride particles placed on the placement plate 302 can absorb and combine the moisture inside the box body 1 during the use of the metering box to form hydrates, which are accumulated in a short period of time and discharged in time through the dehumidification rack 301 and the U-shaped water pipe 314, thereby effectively removing the moisture inside the box body 1, maintaining a dry environment inside the box body 1, and preventing the long-term retention of moisture inside the box body 1 and causing corrosion to the electrical components inside the metering box, thereby improving the performance of the components, ensuring the normal operation of the metering equipment, improving the accuracy of the measurement, and improving the insulation performance of the electrical equipment inside the metering box, thereby reducing the risk of electric shock and short circuit, and ensuring the safe operation of the power system.

[0027] The complete usage steps and working principle of the above embodiment are as follows: The following is the working process of the liquid discharge control mechanism 3 monitoring the weight of the calcium chloride particles placed on the placement plate 302 in real time and automatically discharging the hydrates when the calcium chloride particles on the placement plate 302 form hydrates: like Figure 3 and Figure 6As shown, in the initial state, calcium chloride particles are evenly placed on the placement plate 302. Since the placement plate 302 is slidably arranged on the inner wall of the dehumidification rack 301 through the slider 303 and the slide groove 304, and a first return spring 305 is fixedly arranged between the slider 303 and the inner bottom wall of the slide groove 304, the placement plate 302 can be driven to slide downward inside the dehumidification rack 301 through the gravity of the calcium chloride particles themselves, so that the first return spring 305 is compressed synchronously. At this time, the slider 303 keeps a certain distance from the switch 306 and will not trigger the switch 306. When the calcium chloride particles placed on the placement plate 302 form hydrates after a long period of use, it should be noted that a plurality of meshes are provided on the placement plate 302 for the hydrate to penetrate and flow out. At this time, as the hydrate penetrates downward, the gravity on the placement plate 302 disappears synchronously, and the first return spring 3 05, the slider 303 can be driven to slide upward inside the slide groove 304, so that the placement plate 302 is synchronously moved up and reset, and finally one of the sliders 303 is in contact with the switch 306. It should also be noted that this switch 306 is electrically connected to the external driving source connected to the reciprocating screw rod 403 in the uniform feeding mechanism 4. When this switch 306 is touched and turned on, the external driving source can be started to start running, so that the uniform feeding mechanism 4 starts to operate to replenish new calcium chloride particles. The specific process is shown below and will not be elaborated on here. In this process, the placement plate 302 is installed in the dehumidification rack 301 in an elastic connection mode, and the gravity of the calcium chloride particles on the placement plate 302 is combined to monitor and judge the use of the calcium chloride particles on the placement plate 302, thereby reflecting the consumption status of the calcium chloride particles in real time; When the calcium chloride particles placed on the placement plate 302 are used up, as the weight is reduced, the slider 303 can be pushed to slide upward inside the slide groove 304 under the elastic force of the first return spring 305, and the placement plate 302 is simultaneously moved upward and reset. Figure 3 and Figure 4 As shown, since the U-shaped slide plates 307 are symmetrically fixedly arranged at the front and rear ends of the placement plate 302, and the U-shaped slide plate 307 is vertically slidably arranged on the dehumidification rack 301, when the placement plate 302 moves upward, the U-shaped slide plate 307 can be synchronously driven to move upward on the dehumidification rack 301. In addition, since a bottom frame 309 is fixedly arranged between the dehumidification rack 301 and the inner bottom wall of the box body 1, and a fixed plate 310 is symmetrically fixedly arranged on the outer walls of the front and rear sides of the bottom frame 309, a connecting block 311 is slidably arranged on the fixing plate 310, and a linkage plate 308 is rotatably arranged between the connecting block 311 and the U-shaped slide plate 307, which can be referred to Figure 4Initially, calcium chloride particles are placed on the placement plate 302. When the placement plate 302 is driven downward by gravity, the inner top wall of the U-shaped slide plate 307 can be completely placed on the upper surface of the dehumidification rack 301. At this time, the connecting block 311 is also pushed by the linkage plate 308 and is set at the right end of the fixed plate 310. When the calcium chloride particles on the placement plate 302 are used up, the placement plate 302 drives the U-shaped slide plate 307 to move upward synchronously, and the connection of the linkage plate 308 can make the connecting block 311 move from the right end of the fixed plate 310 to the left. The end of the dehumidification rack 301 slides, and a push plate 312 is symmetrically fixed on the left side of the connection block 311. When the connection block 311 moves, the push plate 312 moves synchronously. When the placement plate 302 moves up to make the slider 303 contact the switch 306, since a U-shaped water pipe 314 is fixedly installed at the lower end of the dehumidification rack 301, and a notch 315 is vertically opened on the outer surface of the middle part of the U-shaped water pipe 314, the hydrate permeated on the placement plate 302 will flow toward the notch 315 and enter the interior of the U-shaped water pipe 314 through the notch 315; Because both ends of the U-shaped water pipe 314 are fixedly connected to the fixing frame 316, the lower end of the fixing frame 316 is fixedly connected to the drainage pipe 321, and the sealing plate 320 is slidably arranged inside the fixing frame 316, Figure 5 It can be seen that the sealing plate 320 is initially arranged between the U-shaped water pipe 314 and the drain pipe 321 to block the connection channel between the U-shaped water pipe 314 and the drain pipe 321. As the connection block 311 moves to the left, the left side of the push plate 312 contacts the right side of the sealing plate 320, and the sealing plate 320 is pushed out to the left from the fixing frame 316. At this time, the moving blocks 319 installed on both sides of the sealing plate 320 will synchronously slide to the left in the connecting grooves 317 opened on both sides of the fixing frame 316, and squeeze the second return spring 318 installed between the moving block 319 and the connecting groove 317. In this process, the pushing movement of the sealing plate 320 by the push plate 312 can remove the obstruction between the U-shaped water pipe 314 and the drain pipe 321, thereby realizing the connection between the U-shaped water pipe 314 and the drain pipe 321, and discharging the hydrate entering the U-shaped water pipe 314. Among them, Figure 3 and Figure 4As shown, drainage plates 313 are symmetrically fixedly arranged on the inner walls on both sides of the lower end of the dehumidification rack 301, and a U-shaped water pipe 314 is arranged between the two drainage plates 313, and the upper surface of the drainage plate 313 is arranged as an inclined surface, and the height of the drainage plate 313 toward one end of the U-shaped water pipe 314 is lower than the height of the drainage plate 313 away from one end of the U-shaped water pipe 314, that is, the drainage plate 313 can form a natural guiding path for hydrates through the action of the inclined surface when in use, and drain them toward the notch 315 opened on the upper surface of the U-shaped water pipe 314, so that the hydrates can flow into the U-shaped water pipe 314 more concentratedly and faster, thereby improving the drainage efficiency, reducing the retention time of the hydrates in the dehumidification rack 301, and helping to keep the inside of the dehumidification rack 301 dry and clean; At the same time, as the slider 303 moves upward, it touches the switch 306, and the uniform feeding mechanism 4 is started to operate synchronously, and the calcium chloride particles on the placement plate 302 are supplemented. With the continuous supplementation of calcium chloride particles, the number of calcium chloride particles on the placement plate 302 increases, and the placement plate 302 can be moved downward inside the dehumidification rack 301 under the action of gravity, and the slider 303 is synchronously driven to compress the first return spring 305, and the U-shaped slide plates 307 arranged on both sides of the placement plate 302 are synchronously moved downward on the dehumidification rack 301. Through the connection of the linkage plate 308, the connection block 311 can be driven to slide from the left end to the right end of the fixed plate 310, and the push plate 312 is moved from the fixed rack 3 16 is moved to the right, at this time, under the elastic force of the second return spring 318, the sealing plate 320 can be synchronously moved to the right with the withdrawal of the push plate 312, and finally reset to the inside of the fixing frame 316 (i.e., between the U-shaped water pipe 314 and the drainage pipe 321), and the communication channel between the U-shaped water pipe 314 and the drainage pipe 321 is blocked for the next use. Therefore, the set drainage control mechanism 3 can realize the real-time monitoring of the use status of the calcium chloride particles and the automatic discharge of the hydrate through a series of mechanical linkage and electrical control. When the calcium chloride particles form hydrates, the mechanism can automatically sense and start the drainage process without manual intervention, which greatly improves the automation of the equipment; In the above process, by setting the drainage control mechanism 3, the gravity exerted on the placement plate 302 by the weight of the calcium chloride particles placed on the placement plate 302 is utilized, and in combination with the elastic effect of the first reset spring 305, the use of the calcium chloride particles on the placement plate 302 can be monitored in real time, and after the calcium chloride particles are used up to form hydrates, the drainage process can be automatically sensed and started, and the formed hydrates are discharged from the dehumidification rack 301, thereby eliminating the need for manual intervention for regular inspections or manual drainage, reducing the dependence on operators, thereby improving the degree of automation of the equipment, and by real-time monitoring of the use of the calcium chloride particles, the continuity of the dehumidification process can be ensured, and the retention time of the hydrates in the dehumidification rack 301 can be reduced, thereby avoiding a decrease in dehumidification efficiency due to the exhaustion of particles and failure to replace them in time; Among them, the design of the guide plate 313 and the U-shaped water pipe 314 can guide the hydrate to flow quickly and concentratedly to the drain port, reducing the diffusion and retention time of the hydrate inside the dehumidification rack 301, and because the upper surface of the guide plate 313 is set as an inclined surface, a natural flow path can be provided for the hydrate, reducing the resistance of the hydrate flow, thereby improving the drainage effect; Please refer to the above working process Figures 1 to 8 .

[0028] The following is a working process of the uniform feeding mechanism 4 uniformly replenishing the calcium chloride particles on the placement plate 302 after the calcium chloride particles placed on the placement plate 302 are used up: It should be noted in advance that if Figure 2 As shown, one end of the reciprocating screw rod 403 is fixedly connected to the output end of an external driving source, and the external driving source can be a driving motor, which is used to drive the reciprocating screw rod 403 to rotate on the U-shaped mounting frame 402, and the driving motor can be fixedly arranged on the side plate 401 when in use; When the calcium chloride particles on the placement plate 302 are used up, as the weight is reduced, the slider 303 can be driven to cooperate with the placement plate 302 to move upward synchronously with the inside of the dehumidification rack 301 under the elastic force of the first return spring 305, and the slider 303 finally touches the switch 306. At this time, since the switch 306 is electrically connected to the driving source connected to the reciprocating screw 403, when the switch 306 is turned on, the driving source can be synchronously started to start running, driving the reciprocating screw 403 to rotate on one of the U-shaped mounting frames 402, as shown in FIG. Figure 2 , Figure 7 as well as Figure 8As shown, two U-shaped mounting brackets 402 are symmetrically fixedly arranged between the side plate 401 and the left inner wall of the box body 1, one of the U-shaped mounting brackets 402 is used to rotatably arrange the reciprocating screw rod 403, and the other U-shaped mounting bracket 402 is used to fix the sliding rod 404, and the outer surfaces of the sliding rod 404 and the reciprocating screw rod 403 are both provided with linkage blocks 405, and the linkage block 405 arranged on the outer surface of the reciprocating screw rod 403 is threadedly connected to the reciprocating screw rod 403, and the linkage block 405 arranged on the outer surface of the sliding rod 404 is slidably connected to the sliding rod 404, and a material dispensing cylinder 406 is fixedly arranged between the tops of the two linkage blocks 405, so when the driving source drives the reciprocating screw rod 403 to rotate on one of the U-shaped mounting brackets 402, through the threaded connection, The linkage block 405 threadedly connected to the outer surface of the reciprocating screw rod 403 can be driven to move synchronously with the outer surface of the reciprocating screw rod 403. Through the connection of the material-dispensing barrel 406, the two linkage blocks 405 can form a whole. When one of the linkage blocks 405 is driven to move by the thread, the other linkage block 405 arranged on the outer surface of the slide rod 404 can be synchronously driven to slide synchronously with the outer surface of the slide rod 404. In addition, because a linkage shaft 408 is rotatably provided in the middle of the material-dispensing barrel 406, and gears 410 are symmetrically fixedly provided at both ends of the linkage shaft 408, and tooth plates 411 meshing with the gears 410 are fixedly provided on the U-shaped mounting frame 402, when the two linkage blocks 405 move synchronously, the tooth plates 411 arranged on the two linkage blocks 405 The material-shifting cylinder 406 will also move synchronously, moving from the left side of the upper end of the dehumidification rack 301 to the right side of the upper end of the dehumidification rack 301, and then moving from the right side of the upper end of the dehumidification rack 301 to the left side of the upper end of the dehumidification rack 301. As the material-shifting cylinder 406 moves horizontally, the linkage shaft 408 installed through the material-shifting cylinder 406 will move synchronously, causing the gear 410 to move synchronously above the tooth plate 411. Through the meshing connection between the teeth of the tooth plate 411 and the gear 410, the gear 410 can be driven to rotate synchronously above the tooth plate 411 with the linkage shaft 408 as the axis while the gear 410 moves. Because the outer surface of the linkage shaft 408 is annular and equidistantly fixed with multiple material-shifting plates 409, and the material-shifting plates 409 is arranged inside the material-dispensing barrel 406. With the rotation of the linkage shaft 408, the material-dispensing plate 409 can be driven to rotate synchronously inside the material-dispensing barrel 406 with the linkage shaft 408 as the axis. Since the top of the material-dispensing barrel 406 is fixedly connected to the storage bin 407, and the bottom of the material-dispensing barrel 406 itself is provided with a discharge port, calcium chloride particles are stored inside the storage bin 407. Through the connection with the material-dispensing barrel 406, the calcium chloride particles can enter the material-dispensing barrel 406, that is, the gap between two adjacent material-dispensing plates 409 at the upper end of the material-dispensing barrel 406. With the rotation of the material-dispensing plate 409 inside the material-dispensing barrel 406, the calcium chloride particles can be rotated in batches inside the material-dispensing barrel 406 and finally discharged downward. In addition, according to the equidistant arrangement of the material-dispensing plates 409,It can intervene in the feeding action of calcium chloride granules, so that calcium chloride granules can be fed one by one, avoiding congestion caused by excessive and fast feeding of materials, and at the same time, it can also effectively control the feeding amount of calcium chloride granules; Among them, Figure 7 and Figure 8 As shown, a flow-aiding plate 412 is fixedly arranged between the bottoms of the two linkage blocks 405, and the flow-aiding plate 412 is inclined, and a connecting rod 413 is symmetrically fixedly arranged at its bottom end. Moving grooves 414 are symmetrically provided on the inner walls of the front and rear sides of the dehumidification rack 301, and the connecting rod 413 and the moving groove 414 are slidably connected. When the linkage block 405 moves and drives the material-diverting plate 409 to rotate to discharge the calcium chloride particles, the calcium chloride particles discharged by the material-diverting plate 409 can be assisted in discharging. By utilizing the inclined characteristics of the flow-aiding plate 412, The outflow of the material provides a guiding path, so that the calcium chloride particles can slide out from the upper surface of the flow-aiding plate 412 and slowly fall onto the placement plate 302, thereby slowing down the feeding speed of the calcium chloride particles, avoiding the situation where the calcium chloride particles collide and splash due to the excessive feeding speed, thereby maintaining the cleanliness of the internal environment of the box 1. At the same time, by slowing down the feeding speed of the calcium chloride particles, it is also possible to avoid the situation where the placement plate 302 is suddenly impacted due to the excessive feeding speed, thereby damaging the first return spring 305 and affecting its return effect; In the above process, by setting the uniform feeding mechanism 4, the slider 303 moves upward to touch the switch 306, so that the reciprocating screw rod 403 can be synchronously driven to rotate, and the material-dispensing barrel 406 is driven to move horizontally above the dehumidification rack 301, and the meshing connection between the gear 410 and the toothed plate 411 can be coordinated, so that the material-dispensing plate 409 arranged in an annular shape and equidistant on the outer surface of the linkage shaft 408 can be rotated inside the material-dispensing barrel 406, and the calcium chloride particles in the storage bin 407 are dispensed in batches, thereby intervening in the feeding action of the calcium chloride particle material, so that the calcium chloride particle material can be fed one by one, avoiding the situation that the material is fed too much and too fast and causes congestion, and at the same time, the feeding amount of the calcium chloride particles can be effectively controlled; The flow-aiding plate 412 provided below the material-dispensing cylinder 406 can provide a guiding path for the outflow of the material by cooperating with its inclined characteristics, so that the calcium chloride particles can slide out from the upper surface of the flow-aiding plate 412 and slowly fall onto the placement plate 302, thereby slowing down the feeding speed of the calcium chloride particles, avoiding the situation where the calcium chloride particles collide and splash due to the excessive feeding speed, thereby maintaining the cleanliness of the internal environment of the box 1. At the same time, by slowing down the feeding speed of the calcium chloride particles, it is also possible to avoid the situation where the placement plate 302 is suddenly impacted due to the excessive feeding speed, thereby damaging the first return spring 305 and affecting its return effect; In summary, through the coordinated use of the liquid discharge control mechanism 3 and the uniform feeding mechanism 4, the calcium chloride particles placed on the placement plate 302 can absorb and combine the moisture inside the box body 1 during the use of the metering box to form hydrates, which are accumulated in a short period of time and discharged in time through the dehumidification rack 301 and the U-shaped water pipe 314, thereby effectively removing the moisture inside the box body 1, maintaining a dry environment inside the box body 1, and preventing the long-term retention of moisture inside the box body 1 from corroding the electrical components inside the metering box, thereby improving the performance of the components, ensuring the normal operation of the metering equipment, improving the accuracy of the metering, and improving the insulation performance of the electrical equipment inside the metering box, thereby reducing the risk of electric shock and short circuit, and ensuring the safe operation of the power system; Please refer to the above working process Figures 1 to 8 .
