Description

Technical Field

[0001] The 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 increasingly valued. The traditional meter box design often has problems such as insufficient safety protection, insufficient durability and poor environmental adaptability, which cannot meet the high requirements of modern power systems for equipment safety and reliability. Therefore, the research and development of a customized meter box hierarchical safety protection system came into being;

[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 meter box layered safety protection system:

[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 an electric meter box has the following beneficial effects:

[0024] 1. Through the cooperation among the protective box, the electric meter box, the servo motor, the monitoring components and the ventilation components, the device can discharge the heat in the inner cavity of the electric meter box while monitoring the temperature of the electrical components in the inner cavity of the electric meter box, so as to avoid the problem of short circuit of the electrical components and shortening the service life of the electrical components due to the temperature rise in the inner cavity of the electric meter box; through the rotation of the straight plate and the inclined plate, the gear one rotates 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 activity 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 electric meter box is ventilated and heat is dissipated, so that the heat in the inner cavity of the electric meter box can be discharged, and the problem of the influence of the temperature rise in the inner cavity of the electric meter box on the electrical components is avoided.

[0025] 2. Through the cooperation between the ventilation components and the monitoring components, the device can seal the inner cavity of the protection box when heat dissipation is not required, thereby 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; the pushing wheel rolls on the surface of the arc plate to push the sliding rod to move the circular plate, so that the circular plate and the protection box are separated, thereby opening the ventilation holes for heat dissipation. If the temperature in 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 protection 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 the multiple ventilation components in the device correspond to those of the circuit breaker, the power switch and the multiple electric energy meters, so that the temperature sensor can ventilate and dissipate heat around the electrical component when it detects 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 will stop 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 avoiding the impact of the temperature increase on 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 the wires to spontaneously combust, the servo motor can reverse to close the circuit breaker, thereby stopping the electrical components from working, thereby preventing the problem of spontaneous combustion of the electrical components in the inner cavity of the meter box due to the increase in the inner cavity temperature of the meter box; when the inner cavity temperature of the meter box is too high, which may cause the wires in the inner cavity of the meter box to spontaneously combust, 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, stopping the electric energy meter and the power switch from working, thereby 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 will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a customized meter box layered safety protection system. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] Embodiment 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 upper end face. The upper end face does not have ventilation holes to prevent rainwater from falling into the inner cavity of the mounting frame 10.

[0059] Next, a protection box 20 is fixed to one side of the mounting frame 10, and a servo motor 50 is fixed to one side of the protection box 20. The servo motor 50 is installed on a side close to the mounting frame 10, and the servo motor 50 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 protection 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 protection box 20 through a connecting plate. The connecting plate is fixed on the side wall of the inner cavity of the protection box 20. The fixed gear 70 is located in the middle of the inner cavity of the protection 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 groups of ventilation holes are opened on one side of the protection box 20, and the two groups of ventilation holes are symmetrical. The ventilation holes penetrate the protection box 20 and can be ventilated. Ventilation components 80 are fixed in the inner cavities of the two groups of ventilation holes. The ventilation components 80 can close the ventilation holes in a normal state to prevent rain and dust from entering.

[0062] like Fig.11As shown, the plurality of ventilation components 80 are distributed in a ring shape, and the center of the plurality of ventilation components 80 is in the same straight line as the center of the fixed gear 70, so that the plurality of ventilation components 80 can be opened correspondingly 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, a meter box 30 is fixed to one side of the protection box 20 away from the mounting frame 10, and a circuit breaker 32, a power switch 33 and a plurality of electric energy meters 31 are installed in the inner cavity of the meter box 30. The plurality of electric energy meters 31 are installed on one side of the inner cavity of the 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 meter box 30. Fig.12 As shown, the circuit breaker 32, the power switch 33 and the plurality of electric energy meters 31 are arranged in a square shape.

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

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

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

[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 on the surface of the output end of the servo motor 50 and can rotate with the rotation of the output end of the servo motor 50. The straight plate 61 and the inclined plate 67 are respectively rotatably installed with a gear 1 62 and a gear 2 65 on the side away from the output end of the monitoring component 60. The gear 2 65 is meshed with the gear 1 62. The gear 1 62 is away from the fixed gear 70 and does not contact the fixed gear 70. The 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 the gear 2 65 outside the fixed gear 70. Since the gear 2 65 is meshed with the fixed gear 70, the gear 2 65 can rotate by itself, thereby rotating with the gear 1 62.

[0068] Next, a driving wheel 66 is fixedly installed on one side of the straight plate 61, and the driving wheel 66 is adapted to the ventilation component 80. The rotation center of the driving wheel 66 is on the same straight line as the center of the fixed gear 70, so that when the straight plate 61 rotates with the driving wheel 66, the driving wheel 66 always keeps in contact with the multiple ventilation components 80, drives the multiple ventilation components 80, and enables the ventilation holes to ventilate;

[0069] The monitoring component 60 further includes a temperature sensor 64, which is used to detect the temperature at the installation position of the electric energy meter 31, the circuit breaker 32 and the power switch 33, to prevent the temperature from being too high without taking measures, resulting in damage to the device due to excessive temperature. A cam plate 63 coaxial with the gear 1 62 is fixedly installed on one side of the gear 1 62, and the temperature sensor 64 is eccentrically installed on the cam plate 63. The rotation of the gear 1 62 causes the cam plate 63 to rotate with the temperature sensor 64, and 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, such as Fig.13 and Fig.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 on the side wall of the ventilation hole. A slide bar 82 is slidably mounted on one side of the mounting plate 81. The slide bar 82 penetrates the mounting plate 81 and is slidably mounted on the mounting plate 81. An arc plate 83 is fixedly mounted on one side of the slide bar 82. A circular plate 85 is fixedly mounted on the side of the slide bar 82 away from the arc 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 protection 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 arc plate 83. The two support springs 84 are used to support the arc plate 83 so that the arc plate 83 can be reset after being pushed.

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

[0074] By rotating the monitoring component 60, the activity 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, and the temperature of the energy meter 31, the circuit breaker 32 and the power switch 33 is monitored. The activity 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 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, which can prevent the ventilation holes from being opened for a long time, causing dust and rainwater to enter the inner cavity of the meter box 30 and damage the electrical components.

[0075] Next, when the temperature sensor 64 monitors the temperature of the installation location of the power 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 driving wheel 66 at the same position also controls the ventilation component 80 to keep the ventilation hole in an open state for a long time to ventilate and dissipate heat at the location to avoid damage to electrical components due to excessive temperature.

[0076] Embodiment 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, Fig.15 As shown, the matching component 90 includes a telescopic plate 91, which is fixedly installed at 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 installed 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 installed on the side of the connecting block 92 away from the telescopic plate 91 through a torsion spring, and a limiting groove 94 is provided on one side of the mounting column 93.

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

[0080] Next, a fixing plate 43 is fixedly installed on one side of the fixing block 41, and a return spring 42 connected to the horizontal portion of the L-shaped plate 45 is fixedly installed 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 column 44 adapted to the circuit breaker 32 is fixedly installed on one side of the vertical portion of the L-shaped plate 45. The push column 44 contacts the switch handle of the circuit breaker 32. The push column 44 moves downward to push the switch handle of the circuit breaker 32 downward, so that the circuit breaker 32 is turned off, and the energy meter 31, the circuit breaker 32 and the power switch 33 are turned off.

[0082] During the forward rotation of the servo motor 50, the mounting column 93 contacts the connecting rod 46, so that the connecting block 92 rotates in one direction, which will not affect the operation of the device. During the reverse rotation of the servo motor 50, the connecting rod 46 is located in the inner cavity of the limit groove 94. The connecting block 92 will not rotate either. As the telescopic plate 91 rotates, the connecting rod 46 moves downward, and at the same time, the column 44 moves downward to close the circuit breaker 32, preventing the temperature in the inner cavity of the meter box 30 from continuing to rise and causing the wires to spontaneously ignite.

[0083] It should be noted that the meter box 30, the energy meter 31, the circuit breaker 32, the power switch 33, the servo motor 50, the temperature sensor 64 and the telescopic plate 91 in the present invention are all prior arts, 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 meter box layered safety protector system, which can monitor the temperature of the electrical components in the inner cavity of the meter box 30, and can perform fixed-point ventilation and heat dissipation on the electrical components at different positions to discharge the heat in the inner cavity of the meter box 30, and can also prevent the ventilation holes from being opened for a long time to cause rainwater and dust to enter the inner cavity of the meter box 30, so as to achieve the purpose of dustproof and waterproof;

[0085] Specifically, when the device is operating normally, the servo motor 50 rotates forward, driving the straight plate 61 and the inclined plate 67 to rotate, so that the inclined plate 67 drives 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 driving 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 after one rotation coincides with the track of the installation position of the electric energy meter 31, the circuit breaker 32 and the power switch 33. Fig.13 and Fig.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, Fig.10 As shown, during the rotation of the straight plate 61, the driving wheel 66 rotates with the straight plate 61, and the driving wheel 66 rolls with the surface of the arc plate 83. During the rotation of the driving wheel 66, the arc plate 83 can be pushed to separate the circular plate 85 from the protection box 20, and the ventilation holes are opened to ventilate and dissipate heat in the inner cavity of the electric 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 plate 83 is pushed to move by the push wheel 66, so that the energy meter 31, the circuit breaker 32 and the power switch 33 can be cooled while being monitored, thereby avoiding the problem that dust and rainwater enter 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, so that the driving wheel 66 corresponds to the location where the temperature is too high, so that the circular plate 85 releases the sealing of the ventilation hole, and the location is cooled for a long time, thereby improving the efficiency of the device in discharging heat and preventing the temperature from affecting the electrical components in the inner 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 ignite, the temperature sensor 64 detects this situation and the servo motor 50 will reverse. Fig.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, and the mounting column 93 rotates to push the connecting rod 46 downward, and the connecting rod 46 moves downward, so that the L-shaped plate 45 moves downward with the pushing column 44, and the switch handle on the circuit breaker 32 is pushed 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 description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
