Description

Technical Field

[0001] The present invention relates to the technical field of electric meter box protection devices, and in particular to a customized electric meter box layered safety protection system. Background Art

[0002] With the continuous development and improvement of the power system, the safety and reliability of the meter box, as an important device for power distribution and metering, are receiving increasing attention. Traditional meter box designs often have problems such as insufficient safety protection, insufficient durability, and poor environmental adaptability. They cannot meet the high requirements of modern power systems for equipment safety and reliability. Therefore, the research and development of a customized layered safety protection system for meter boxes has emerged.

[0003] During the use of the meter box, since the overall structure of the meter box is closed, the heat generated when the meter is running cannot be discharged, which will cause the temperature inside the meter box to rise, which may not only cause the meter to short circuit, but also shorten the service life of the meter; the ventilation holes on the box body of some meter boxes are fixed in position, so that the heat emitted by the electrical components cannot be discharged in time, resulting in insufficient heat dissipation efficiency of the device, and dust and flying insects often enter the meter box. When it rains, rainwater may also drip in, which will also affect the normal operation of the meter. Summary of the Invention

[0021] As a further description of the above technology, a customized layered safety protection system for electric meter boxes:

[0022] A pushing column is fixedly installed on one side of the vertical portion of the L-shaped plate.

[0023] In summary, due to the adoption of the above-mentioned technology, a customized hierarchical safety protection system for electric meter boxes has the following beneficial effects:

[0024] 1. This device can discharge the heat of the inner cavity of the meter box while monitoring the temperature of the electrical components in the inner cavity of the meter box through the cooperation between the protective box, the meter box body, the servo motor, the monitoring components and the ventilation components, so as to avoid the problem of short circuit of the electrical components and shortening of the service life of the electrical components due to the temperature rise in the inner cavity of the meter box; by rotating the straight plate and the inclined plate, the gear one rotates along with the straight plate, and the gear two drives the gear one to rotate, so that the temperature sensor rotates eccentrically, and the straight plate rotates one circle, and the moving trajectory of the temperature sensor coincides with the installation position trajectory of multiple electrical components, so that the temperature of the electrical components installed in different positions can be monitored. At the same time, during the rotation of the straight plate, the pushing wheel rotates accordingly, and the pushing wheel will push the arc plate, and the circular plate and the protective box are separated by the sliding rod, so that the ventilation hole is opened, and the inner cavity of the meter box is ventilated and dissipated, so that the heat of the inner cavity of the meter box can be discharged, and the problem of the temperature rise in the inner cavity of the meter box affecting the electrical components is avoided.

[0025] 2. Through the cooperation between the ventilation components and the monitoring components, this device can seal the inner cavity of the protective box when heat dissipation is not required, preventing dust, flying insects and rainwater from entering the inner cavity of the meter box, thus avoiding the problem of dust, flying insects and rainwater entering the inner cavity of the meter box and causing damage to electrical components; by pushing the wheel to roll on the surface of the arc plate, the slide rod moves with the circular plate, separating the circular plate and the protective box, thereby opening the ventilation hole for heat dissipation. If the temperature of the inner cavity of the meter box is not high, the servo motor will not rotate. At this time, all ventilation components are in normal state, and the circular plate is also tightly attached to the protective box, which can prevent dust and other impurities from entering the inner cavity of the meter box, thus avoiding the problem of dust and rainwater entering the inner cavity of the meter box due to the ventilation holes being open for a long time and causing damage to electrical components.

[0026] 3. The positions of multiple ventilation components in this device correspond to those of the circuit breaker, power switch and multiple electricity meters, so that the temperature sensor can ventilate and dissipate heat around the electrical component when it monitors the electrical component, thereby improving the efficiency of heat discharge around the electrical component.

[0027] 4. When the temperature of the energy meter, circuit breaker or power switch in a certain area rises, the temperature sensor detects that the temperature at that location is too high, and the servo motor stops rotating, so that the driving wheel corresponds to the position where the temperature is too high, so that the circular plate releases the seal on the ventilation hole, and the position is cooled for a long time, thereby improving the efficiency of the device in dissipating heat and preventing the temperature increase from affecting the electrical components in the inner cavity of the meter box.

[0028] 5. Through the coordination among the monitoring components, matching components and disconnecting components, when the temperature in the inner cavity of the meter box rises to a level that may cause spontaneous combustion of the wires, the servo motor reverses to close the circuit breaker, thereby stopping the electrical components from working, thus preventing the problem of spontaneous combustion of the electrical components in the inner cavity of the meter box due to the temperature rise in the inner cavity of the meter box; when the temperature in the inner cavity of the meter box is too high, which may cause spontaneous combustion of the wires in the inner cavity of the meter box, when the temperature sensor detects this situation, the servo motor will reverse to make the connecting rod located in the inner cavity of the limit slot, and then the telescopic plate will continue to rotate with the mounting column, and the mounting column will rotate to push the connecting rod downward, and the connecting rod will move downward, causing the L-shaped plate to move the pushing column downward, pushing the switch handle on the circuit breaker downward, so that the electric energy meter and the power switch will stop working, thus avoiding the problem of fire in the inner cavity of the meter box due to excessively high temperature, thereby achieving the purpose of fire prevention.

[0056] The following, combined with the accompanying drawings, provides a clear and complete description of the technology in the embodiments of the present invention, a customized layered safety protection system for an electricity meter box. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0057] Example 1

[0058] like Figure 1-Figure 3 As shown, a customized layered safety protection system for an electric meter box includes a mounting frame 10. The mounting frame 10 is a square frame. Ventilation slots are provided on all end faces except the top end face. The top end face does not have ventilation holes to prevent rainwater from falling into the inner cavity of the mounting frame 10.

[0059] Next, a protective box 20 is fixed to one side of the mounting frame 10, and a servo motor 50 is fixed to one side of the protective box 20. The servo motor 50 is installed on the side close to the mounting frame 10 and is located in the middle of the inner cavity of the mounting frame 10. Since the upper end surface of the mounting frame 10 is closed, rainwater will not fall on the servo motor 50.

[0060] like Figure 4 and Figure 5 As shown, a monitoring component 60 and a matching component 90 are fixed to the output end of the servo motor 50. Both the monitoring component 60 and the matching component 90 are located in the inner cavity of the protective box 20. The matching component 90 is close to one side of the servo motor 50. A fixed gear 70 adapted to the monitoring component 60 is fixed to the inner cavity of the protective box 20 through a connecting plate. The connecting plate is fixed to the side wall of the inner cavity of the protective box 20. The fixed gear 70 is located in the middle of the inner cavity of the protective box 20. The center of the fixed gear 70 is on the same horizontal line as the center of the output end of the servo motor 50, so that the components in the monitoring component 60 can rotate around the fixed gear 70.

[0061] Among them, two sets of ventilation holes are opened on one side of the protective box 20. The two sets of ventilation holes are symmetrical and penetrate the protective box 20 for ventilation. Ventilation components 80 are fixed in the inner cavity of the two sets of ventilation holes. The ventilation components 80 can close the ventilation holes under normal conditions to prevent rain and dust from entering.

[0062] like Figure 11As shown, the plurality of ventilation components 80 are distributed in a ring shape, and the center of the ring-shaped distribution of the plurality of ventilation components 80 is on the same straight line as the center of the fixed gear 70, so that the plurality of ventilation components 80 can be opened accordingly during the rotation of the monitoring component 60 to ventilate and dissipate heat while preventing rainwater from entering;

[0063] Then, if Figure 2 As shown, the protection box 20 is fixed to the side away from the mounting frame 10 with an electric meter box 30, and the inner cavity of the electric meter box 30 is installed with a circuit breaker 32, a power switch 33 and a plurality of electric energy meters 31. The plurality of electric energy meters 31 are installed on one side of the inner cavity of the electric meter box 30, and the circuit breaker 32 and the power switch 33 are installed on the other side of the inner cavity of the electric meter box 30. Figure 12 As shown, the circuit breaker 32, the power switch 33 and the plurality of electric energy meters 31 are distributed in a square shape.

[0064] like Figure 12 As shown, multiple ventilation components 80 correspond to the circuit breaker 32, the power switch 33 and the multiple energy meters 31, which can dissipate heat in a certain area when the temperature rises, thereby improving the heat dissipation effect of the device.

[0065] The energy meter 31, the circuit breaker 32 and the power switch 33 are all electrical components installed in the inner cavity of the meter box 30.

[0066] Next, a disconnect component 40 is fixed in the inner cavity of the meter box 30. The disconnect component 40 can close the circuit breaker 32 when the temperature is too high and may cause the wires to spontaneously combust.

[0067] Further, if Figure 6 and Figure 7 As shown, the monitoring component 60 includes a straight plate 61 and an inclined plate 67 integrally formed with the straight plate 61. The straight plate 61 is fixed to the surface of the output end of the servo motor 50 and can rotate as the output end of the servo motor 50 rotates. The straight plate 61 and the inclined plate 67 are respectively rotatably installed on the side away from the output end of the monitoring component 60. Gear 1 62 and gear 2 65 are meshed with gear 1 62. Gear 1 62 is away from the fixed gear 70 and does not contact the fixed gear 70. Gear 2 65 is meshed with the fixed gear 70. The rotation of the straight plate 61 causes the inclined plate 67 to rotate with gear 2 65 outside the fixed gear 70. Since gear 2 65 is meshed with the fixed gear 70, gear 2 65 can rotate on its own, thereby rotating with gear 1 62.

[0068] Next, a driving wheel 66 is fixedly mounted on one side of the straight plate 61. The driving wheel 66 is adapted to the ventilation components 80. The rotation center of the driving wheel 66 is aligned with the center of the fixed gear 70. This allows the driving wheel 66 to always maintain contact with the multiple ventilation components 80 during the rotation of the straight plate 61 with the driving wheel 66, thereby driving the multiple ventilation components 80 to enable ventilation of the ventilation holes.

[0069] The monitoring component 60 further includes a temperature sensor 64, which is used to detect the temperature at the installation locations of the energy meter 31, the circuit breaker 32, and the power switch 33 to prevent excessive temperature and damage to the device due to failure to take appropriate measures. A cam plate 63 is fixedly mounted on one side of the gear 1 62 and is coaxial with the gear 1 62. The temperature sensor 64 is eccentrically mounted on the cam plate 63. When the gear 1 62 rotates, the cam plate 63 rotates with the temperature sensor 64. At the same time, the gear 1 62 itself also rotates with the straight plate 61.

[0070] Therefore, the trajectory of the temperature sensor 64 during the rotation of the gear 1 62 is approximately a cube, as shown in Figure 13 and Figure 14 As shown, the trajectory is similar to the distribution trajectory of the electric energy meter 31, the circuit breaker 32 and the power switch 33, so the temperature sensor 64 can monitor the temperature thereof.

[0071] Further, if Figure 8 As shown, the ventilation component 80 includes a mounting plate 81, which is fixed to the side wall of the ventilation hole. A slide rod 82 is slidably mounted on one side of the mounting plate 81. The slide rod 82 passes through the mounting plate 81 and is slidably mounted on the mounting plate 81. An arc-shaped plate 83 is fixedly mounted on one side of the slide rod 82. A circular plate 85 is fixedly mounted on the side of the slide rod 82 away from the arc-shaped plate 83. The diameter of the circular plate 85 is larger than the diameter of the ventilation hole.

[0072] In a normal state, the circular plate 85 is in close contact with the protective box 20, closing the ventilation hole to prevent rainwater and dust from entering the inner cavity of the meter box 30. Two symmetrical support springs 84 are fixedly installed between the mounting plate 81 and the curved plate 83. The two support springs 84 are used to support the curved plate 83 so that the curved plate 83 can be reset after being pushed.

[0073] The arc plate 83 is adapted to the driving wheel 66, as shown in FIG. Figure 9 and Figure 10 As shown, the driving wheel 66 rolls on the surface of the arc plate 83, which can push the arc plate 83, so that the slide rod 82 moves with the circular plate 85, and the ventilation hole is opened to ventilate and dissipate heat for the electrical components at the position of the driving wheel 66;

[0074] By rotating the monitoring component 60, the movement trajectory of the temperature sensor 64 coincides with the trajectory of the installation position of the energy meter 31, the circuit breaker 32, and the power switch 33, thereby monitoring the temperature of the energy meter 31, the circuit breaker 32, and the power switch 33. The movement trajectory of the temperature sensor 64 and the trajectory of the installation position of the energy meter 31, the circuit breaker 32, and the power switch 33 are all approximately square. At the same time, the temperature sensor 64 and the driving wheel 66 are on the same horizontal line. During the rotation of the driving wheel 66, the ventilation component 80 can be driven to move, so that the ventilation holes at the installation position of the ventilation component 80 are opened for ventilation and heat dissipation, thereby preventing dust and rainwater from entering the inner cavity of the meter box 30 and damaging electrical components due to the ventilation holes being open for a long time.

[0075] Next, when the temperature sensor 64 monitors the temperature of the installation location of the electricity meter 31, the circuit breaker 32 and the power switch 33, if the temperature in a certain area is too high, the temperature sensor 64 can stay for a long time. At the same time, the push wheel 66 at the same position also controls the ventilation component 80, so that the ventilation hole is in an open state for a long time, ventilating and dissipating heat at the location to avoid damage to electrical components due to excessive temperature.

[0076] Example 2

[0077] This embodiment further defines the matching component 90 and the disconnecting component 40 on the basis of the first embodiment, so as to achieve the purpose of reversing the servo motor 50 to turn off the power switch 33 when the temperature is too high.

[0078] Specifically, such as Figure 15 As shown, the mating component 90 includes a telescopic plate 91, which is fixedly mounted on the output end of the servo motor 50. A connecting block 92 is provided on one side of the telescopic plate 91. The connecting block 92 is rotatably mounted on the telescopic plate 91 through a one-way bearing. At the same time, a torsion spring is installed between the connecting block 92 and the telescopic plate 91 so that the connecting block 92 can be reset after rotation. A mounting column 93 is rotatably mounted on the side of the connecting block 92 away from the telescopic plate 91 through a torsion spring, and a limiting slot 94 is provided on one side of the mounting column 93.

[0079] Further, if Figure 16 and Figure 17 As shown, the disconnect component 40 includes a fixed block 41, which is fixedly mounted in the inner cavity of the meter box 30. An L-shaped plate 45 is slidably mounted on one side of the fixed block 41. One side of the horizontal portion of the L-shaped plate 45 is slidably connected to the fixed block 41. A connecting rod 46 that is adapted to the limiting groove 94 is fixedly mounted on one side of the vertical portion of the L-shaped plate 45. The inner cavity of the meter box 30 is also provided with a sliding groove for the connecting rod 46 to move downward.

[0080] Next, a fixing plate 43 is fixedly mounted on one side of the fixing block 41. A return spring 42 connected to the horizontal portion of the L-shaped plate 45 is fixedly mounted on the upper side of the fixing plate 43. The return spring 42 is used to support the L-shaped plate 45 so that the L-shaped plate 45 can automatically return to its original position after moving downward.

[0081] In addition, a push post 44 adapted to the circuit breaker 32 is fixedly mounted on one side of the vertical portion of the L-shaped plate 45. The push post 44 contacts the switch handle of the circuit breaker 32. When the push post 44 moves downward, the switch handle of the circuit breaker 32 can be pushed downward to turn off the circuit breaker 32, thereby turning off the energy meter 31, the circuit breaker 32 and the power switch 33.

[0082] During forward rotation of the servo motor 50, the mounting post 93 contacts the connecting rod 46, causing the connecting block 92 to rotate unidirectionally without affecting the operation of the device. During reverse rotation of the servo motor 50, the connecting rod 46 is located within the retaining groove 94. The connecting block 92 does not rotate either. As the telescopic plate 91 rotates, the connecting rod 46 moves downward, simultaneously pushing the post 44 downward and closing the circuit breaker 32, preventing the temperature inside the meter housing 30 from continuing to rise and causing the wires to spontaneously combust.

[0083] It should be noted that the meter box 30, energy meter 31, circuit breaker 32, power switch 33, servo motor 50, temperature sensor 64 and telescopic plate 91 in the present invention are all existing technologies, and their installation methods and control methods are also conventional designs, which will not be elaborated in detail in the present invention.

[0084] Working principle of the present invention: This device is a customized layered safety protector system for electric meter boxes. It can monitor the temperature of the electrical components in the inner cavity of the electric meter box 30. At the same time, it can provide targeted ventilation and heat dissipation for the electrical components at different positions, thereby dissipating the heat from the inner cavity of the electric meter box 30. It can also prevent rainwater and dust from entering the inner cavity of the electric meter box 30 due to the ventilation holes being left open for a long time, thereby achieving the purpose of dust and water prevention.

[0085] Specifically, when the device is operating normally, the servo motor 50 rotates forward, causing the straight plate 61 and the inclined plate 67 to rotate, so that the inclined plate 67 causes the gear 2 65 to rotate outside the fixed gear 70. Since the rotation center of the gear 2 65 is on the same straight line as the center of the fixed gear 70, the gear 2 65 rotates under the action of the fixed gear 70, thereby causing the gear 1 62 to rotate.

[0086] Then, the gear 1 62 causes the temperature sensor 64 to rotate eccentrically through the cam plate 63. The moving track of the temperature sensor 64 during one rotation coincides with the track of the installation position of the energy meter 31, the circuit breaker 32 and the power switch 33. Figure 13 and Figure 14 As shown, the electric energy meter 31, the circuit breaker 32 and the power switch 33 at different positions can be monitored to prevent the temperature inside the electric energy meter box 30 from being too high, causing damage to the device;

[0087] Among them, such as Figure 10 As shown, during the rotation of the straight plate 61, the driving wheel 66 rotates along with the straight plate 61, and the driving wheel 66 rolls on the surface of the curved plate 83. During the rotation of the driving wheel 66, the curved plate 83 can be pushed to separate the circular plate 85 from the protective box 20, thereby opening the ventilation holes to ventilate and dissipate heat in the inner cavity of the meter box 30. The multiple ventilation components 80 correspond to different electric energy meters 31, circuit breakers 32, and power switches 33.

[0088] While monitoring the energy meter 31, the circuit breaker 32, and the power switch 33, the arc-shaped plate 83 is pushed by the push wheel 66 to dissipate heat while monitoring the energy meter 31, the circuit breaker 32, and the power switch 33, thereby preventing the problem of dust and rainwater entering the inner cavity of the meter box 30 due to the ventilation holes being open for a long time and causing damage to the electrical components;

[0089] When the temperature of the energy meter 31, circuit breaker 32 or power switch 33 in a certain area rises, the temperature sensor 64 detects that the temperature at that location is too high, and stops the servo motor 50, causing the driving wheel 66 to correspond to the location where the temperature is too high, so that the circular plate 85 releases the seal of the ventilation hole, and the location is cooled for a long time, thereby improving the efficiency of the device in dissipating heat and preventing the temperature increase from affecting the electrical components in the cavity of the meter box 30;

[0090] When the temperature inside the meter box 30 is too high, which may cause the wires inside the meter box 30 to spontaneously combust, the temperature sensor 64 detects this situation and the servo motor 50 will reverse. Figure 17 As shown, the connecting rod 46 is located in the inner cavity of the limiting groove 94, and then the telescopic plate 91 rotates with the mounting column 93 continuously. The mounting column 93 rotates and pushes the connecting rod 46 downward. The connecting rod 46 moves downward, causing the L-shaped plate 45 to move downward with the pushing column 44, pushing the switch handle on the circuit breaker 32 downward, so that the electric energy meter 31 and the power switch 33 stop working, avoiding the problem of fire in the inner cavity of the electric meter box 30 caused by excessive temperature, thereby achieving the purpose of fire prevention.

[0091] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited to this. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes to a customized layered safety protection system for an electric meter box and its inventive concept according to the technology of the present invention, which should be covered by the scope of protection of the present invention.
