Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a JP cabinet. Background Art

[0002] JP cabinet is a new type of integrated control box that integrates power distribution, metering, protection, control and reactive power compensation, also known as JP integrated distribution box.

[0003] Most of the existing JP cabinets are installed outdoors, which are prone to leakage accidents due to weather factors. The existing JP cabinets are generally equipped with current sensors on the outer wall of the cabinet. When leakage occurs in the JP cabinet, the current sensor senses the leakage current and issues an alarm.

[0004] When the JP cabinet is installed outdoors and in an area with a lot of wind and sand, the external environment will carry sand and stones to contact the current sensor, and the yellow sand will contact the current sensor, resulting in poor heat dissipation, decreased sensitivity or false alarms in the current sensor. At the same time, the yellow sand will accumulate at the heat dissipation holes of the cabinet, resulting in poor air circulation inside the cabinet, causing the temperature inside the cabinet to rise. Or when the external humidity is heavy, the moisture will contact the current sensor through the heat dissipation holes. The high temperature causes the performance of the electronic components inside the current sensor to decline, causing the sensor to have errors when detecting leakage. At the same time, moisture will corrode and oxidize the metal parts inside the current sensor, affecting the service life of the current sensor. Summary of the invention

[0005] The purpose of the present invention is to propose a JP cabinet to solve the problem that the performance of electronic components of a current sensor is degraded due to high temperature or moisture, thereby causing errors in the sensor when detecting leakage.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technology: a JP cabinet: comprising a cabinet, a side wall of the cabinet is provided with a protective assembly, an inner wall of the cabinet is fixedly connected to a current sensor, the protective assembly comprises a filter plate fixedly connected to the inner wall of the cabinet, the filter plate is rotatably connected to a rotating rod inside, a blade is fixedly connected to the rotating rod, a plurality of scrapers are rotatably connected to the rotating rod, a second gear is fixedly connected to one side of the scraper, a support frame is fixedly connected to the inside of the cabinet, a first drive assembly is provided on the support frame, the first drive assembly comprises a rack assembly, the rack assembly comprises a first rack and a second rack, the first rack and the second rack are both meshed with the second gear;

[0007] It moves through the first rack and the second rack and meshes with the second gear, causing the scraper to rotate on its own. The scraper contacts the surface of the filter plate and cleans the dust on the surface of the filter plate. Or multiple scrapers are attached to each other to form a circular ring to block the filter plate. By driving the second rack to slide, part of the scraper rotates independently, thereby adjusting the wind force intensity entering the cabinet interior.

[0008] As a further description of a JP cabinet of the above technology:

[0009] The first driving assembly further includes a support plate fixedly connected to one side of the support frame. An electric cylinder is fixedly connected to one side of the support plate. The telescopic end of the electric cylinder is fixedly connected to a moving frame. A support rod is fixedly connected to the moving frame. A turntable is rotatably connected to the support rod. A plurality of connecting plates are fixedly connected to the turntable. The connecting plates are fixedly connected to the first rack and slidably connected to the second rack.

[0010] As a further description of a JP cabinet of the above technology:

[0011] A fixed rod is fixedly connected to one side of the support plate. The moving frame is slidably connected to the fixed rod.

[0012] As a further description of a JP cabinet of the above technology:

[0013] A chute is provided inside the connecting plate. The size of the chute matches the size of the rotating end of the scraper.

[0014] As a further description of a JP cabinet of the above technology:

[0015] A second driving assembly is provided inside the moving frame. The second driving assembly includes a lead screw rotatably connected inside the moving frame. A moving plate is threadedly connected to the lead screw. A connecting rod is fixedly connected inside the moving plate. One end of the connecting rod is fixedly connected to the inside of the second rack.

[0016] As a further description of a JP cabinet of the above technology:

[0017] The second driving assembly further includes a motor fixedly connected inside the moving frame. The output end of the motor is fixedly connected to one end of the lead screw.

[0018] As a further description of a JP cabinet of the above technology:

[0019] A limiting groove is provided on the support rod. The moving plate is slidably connected to the inner wall of the limiting groove.

[0020] As a further description of a JP cabinet of the above technology:

[0021] The shape of the filter plate is set as a frustum of a cone, and a protective ring is fixedly connected to the outer wall of the cabinet body, and the inner wall of the protective ring is in contact with one side of the scraper.

[0022] As a further description of a JP cabinet of the above technology:

[0023] A circuit breaker is fixedly connected inside the cabinet body, and an alarm is fixedly connected to the outer wall of the cabinet body. The alarm, the circuit breaker and the current sensor are electrically connected.

[0024] In summary, due to the adoption of the above technology of a JP cabinet, the beneficial effects of the present invention are:

[0025] 1. Through the current sensor, it can detect whether the cabinet body is leaking electricity, and through the alarm light, it can remind the staff to avoid the problem of electric shock. At the same time, by setting the filter plate, it can keep the air flowing for the current sensor, and can also prevent the cabinet body from being installed in an environment such as a desert where yellow sand is everywhere, and the yellow sand contacts the current sensor, resulting in problems such as poor heat dissipation, decreased sensitivity or false alarms of the current sensor.

[0026] 2. By setting a scraper and a first driving component, when it is sunny, the external wind blows the blades to rotate, and the blades drive the scraper to rotate. At this time, the scraper can be driven to rotate automatically, so that the scraper contacts the surface of the filter plate. Then, the rotating rod is driven to rotate, and the rotating rod drives the scraper to rotate on the surface of the filter plate. At this time, the scraper can clean the yellow sand attached to the filter plate, avoiding the problem that the internal air circulation efficiency of the cabinet body decreases due to the blockage of the filter plate by yellow sand, resulting in an increase in the internal temperature of the cabinet body, and thus causing damage to the electrical components and current sensors inside the cabinet body due to high temperature. When it is at night or in a rainy environment, the scraper can be driven to rotate, so that the scraper forms a circular ring and fits with the protective ring on the outer wall of the cabinet body. At this time, the filter plate can be sealed, and it can prevent external moisture from entering the inside of the cabinet body through the filter plate, thus causing damage to the cabinet body and current sensor due to moisture.

[0027] 3. By setting a scraper and a second driving component, when the scraper cleans the filter plate and the external wind force is relatively large, the lead screw can be driven to rotate. The lead screw drives the moving plate to slide, the moving plate drives the connecting rod to move, the connecting rod drives the second rack to slide, and the second rack meshes with the second gear, so that the second rack drives the scraper to rotate, and the air inlet gap between the two scrapers in contact with the filter plate can be adjusted. By controlling the air volume entering the cabinet body through the size of the air inlet gap, while ensuring the internal heat dissipation of the cabinet body, it can avoid the problem that the internal electrical components of the cabinet body are vibrated by the excessive wind force, resulting in loosening of the connections between the electrical components, thus ensuring the stable operation of the equipment.

[0043] The following will clearly and completely describe a JP cabinet in the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] As Figures 1-13 shown, the present invention provides: including a cabinet 10, a protection component 20 is arranged on the side wall of the cabinet 10, a current sensor 12 is fixedly connected to the inner wall of the cabinet 10, the protection component 20 includes a filter plate 23 fixedly connected to the inner wall of the cabinet 10, a rotating rod 24 is rotatably connected inside the filter plate 23, a blade 3 is fixedly connected to the rotating rod 24, a plurality of scrapers 25 are rotatably connected to the rotating rod 24, a second gear 251 is fixedly connected to one side of the scraper 25, a support frame 21 is fixedly connected inside the cabinet 10, a first driving component 40 is arranged on the support frame 21, the first driving component 40 includes a rack component 48, the rack component 48 includes a first rack 481 and a second rack 482, and both the first rack 481 and the second rack 482 are meshed with the second gear 251.

[0045] As Figures 7-10As shown, the first driving assembly 40 further includes a support plate 41 fixedly connected to one side of the support frame 21. An electric cylinder 43 is fixedly connected to one side of the support plate 41. A moving frame 42 is fixedly connected to the telescopic end of the electric cylinder 43. A support rod 45 is fixedly connected to the moving frame 42. A turntable 46 is rotatably connected to the support rod 45. A plurality of connecting plates 47 are fixedly connected to the turntable 46. The connecting plates 47 are fixedly connected to the first rack 481 and slidably connected to the second rack 482. The first driving assembly 40 includes a rack assembly 48. The rack assembly 48 includes a first rack 481 and a second rack 482. Both the first rack 481 and the second rack 482 are meshed with the second gear 251. A fixing rod 44 is fixedly connected to one side of the support plate 41. The moving frame 42 is slidably connected to the fixing rod 44. A chute is provided inside the connecting plate 47. The size of the chute matches the size of the rotating end of the scraper 25.

[0046] As Figures 2-4 shown, the shape of the filter plate 23 is set as a frustum of a cone. A protective ring 22 is fixedly connected to the outer wall of the cabinet body 10. The inner wall of the protective ring 22 is attached to one side of the scraper 25.

[0047] As Figure 1 shown, a circuit breaker 12 is fixedly connected to the inside of the cabinet body 10. An alarm 13 is fixedly connected to the outer wall of the cabinet body 10. The alarm 13, the circuit breaker 12 and the current sensor 11 are electrically connected.

[0048] Through the movement of the first rack 481 and the second rack 482 and their meshing with the second gear 251, the scraper 25 rotates self - rotatably. The scraper 25 contacts the surface of the filter plate 23 and cleans the dust on the surface of the filter plate 23. Or multiple scrapers 25 are attached to each other to form a circular ring to block the filter plate 23. By driving the second rack 482 to slide, part of the scrapers 25 rotate independently, thereby adjusting the wind force intensity entering the inside of the cabinet body 10.

[0049] Specifically, most existing JP cabinets are installed outdoors and are prone to leakage accidents due to weather factors. Generally, a current sensor 12 is provided on the outer wall of the existing JP cabinet. When the JP cabinet leaks electricity, the current sensor 12 senses the leakage current and issues an alarm.

[0050] When the JP cabinet is installed outdoors and in an area with a lot of wind and sand, the external environment will carry sand and stones to contact the current sensor 12, and the yellow sand will contact the current sensor 12, which will cause the current sensor 12 to have problems with poor heat dissipation, reduced sensitivity or false alarms. At the same time, the yellow sand will accumulate at the heat dissipation holes of the cabinet 10, resulting in poor air circulation inside the cabinet 10, causing the temperature inside the cabinet 10 to rise. Or when the external humidity is heavy, the moisture will contact the current sensor 12 through the heat dissipation holes. The high temperature causes the performance of the electronic components inside the current sensor 12 to decline, causing the sensor to have errors when detecting leakage. At the same time, the moisture will corrode and oxidize the metal parts inside the current sensor 12, affecting the service life of the current sensor 12.

[0051] In order to avoid the above problems, the use of the device is as follows: when the cabinet 10 leaks electricity during use, the current is transmitted to the surface of the cabinet 10, resulting in an imbalance in the current entering and leaving the cabinet 10. After the current sensor 12 detects the current imbalance, it converts it into an electrical signal output, and then transmits the electrical signal to the circuit breaker 12. The circuit breaker 12 disconnects the circuit and turns on the alarm 13. The alarm 13 sounds an alarm and flashes to remind the staff;

[0052] When the external environment is sunny, the external airflow enters the interior of the cabinet 10 through the filter holes on the filter plate 23 to reduce the heat inside the cabinet 10. At this time, the scraper 25 can be set to be in an inclined state and fit the surface of the filter plate 23. The external wind blows toward the blade 3, so that the blade 3 rotates and drives the rotating rod 24 to rotate synchronously. The rotating rod 24 drives a plurality of scrapers 25 to rotate synchronously. The scrapers 25 rotate and clean the impurities accumulated on the surface of the filter plate 23.

[0053] When the outside humidity is heavy or it is rainy weather, the electric cylinder 43 can be turned on to work, and the electric cylinder 43 drives the moving frame 42 to slide on the fixed rod 44, and the moving frame 42 drives the supporting rod 45 to move in the direction of the supporting plate 41, and the supporting rod 45 drives the rotating disk 46 to move synchronously, and the rotating disk 46 drives the connecting plate 47 to slide synchronously, and the sliding groove inside the connecting plate 47 slides on the surface of the rotating end of the scraper 25, and at the same time, the first rack 481 and the second rack 482 slide synchronously, and the first rack 481, the second rack 482 and the second gear 251 are engaged, so that the scraper 25 rotates, and the scraper 25 is away from the surface of the filter plate 23, and rotates to a horizontal level and forms a ring, and one side of the scraper 25 cooperates with the protective ring 22 to seal the filter plate 23 to prevent external rain and moisture from entering the interior of the cabinet 10 through the filter plate 23.

[0054] When the device is in sunny weather, it can drive the scraper 25 to rotate, so that the scraper 25 contacts the surface of the filter plate 23. The scraper 25 can clean the impurities on the surface of the filter plate 23, avoiding the problem that the internal air circulation efficiency of the cabinet 10 decreases due to the blockage of the filter plate 23 by yellow sand, resulting in an increase in the internal temperature of the cabinet 10, and thus causing damage to the electrical components and current sensor 12 in the cabinet 10 due to high temperature;

[0055] When in a night or rainy environment, it can drive the scraper 25 to rotate, so that the scraper 25 forms a circular ring and fits with the protective ring 22 on the outer wall. At this time, the filter plate 23 can be sealed, which can prevent external moisture from entering the interior of the cabinet 10 through the filter plate 23, thus causing damage to the cabinet 10 and the current sensor 12 due to moisture;

[0056] Through the current sensor 12, it can detect whether the cabinet 10 is leaking electricity, and the alarm 13 is used to remind the staff to avoid electric shock. At the same time, the filter plate 23 is set to keep air circulation for the current sensor 12, and it can also prevent the yellow sand in the desert or other yellow sand-filled environments where the cabinet 10 is installed from contacting the current sensor 12, resulting in problems such as poor heat dissipation, decreased sensitivity or false alarms of the current sensor 12.

[0057] As Figure 12 and Figure 13 shown, a second driving component 50 is arranged inside the moving frame 42. The second driving component 50 includes a lead screw 52 rotatably connected inside the moving frame 42. A moving plate 53 is threadedly connected to the lead screw 52. A connecting rod 54 is fixedly connected inside the moving plate 53. One end of the connecting rod 54 is fixedly connected to the inside of the second rack 482. The second driving component 50 further includes a motor 51 fixedly connected inside the moving frame 42. The output end of the motor 51 is fixedly connected to one end of the lead screw 52. A limiting groove is arranged on the support rod 45. The moving plate 53 is slidably connected to the inner wall of the limiting groove.

[0058] Specifically, when it is sunny, the scraper 25 will clean the filter plate 23. When in sunny weather, the external wind force is relatively large. The wind force enters the interior of the cabinet 10 through the gaps between the scrapers 25 and the filter plate 23. The relatively large wind force will blow the internal electrical components, and the electrical components will vibrate due to the wind force impact, resulting in loose connections between the electrical components, thus causing problems for the normal operation of the equipment. When the scraper 25 closes the filter plate 23, it will also cause the problem of decreased heat dissipation capacity of the cabinet 10 in sunny weather;

[0059] To solve the above problems, when the scraper 25 contacts the filter plate 23, the motor 51 can be turned on at this time. The motor 51 drives the lead screw 52 to rotate, and the lead screw 52 drives the moving plate 53 on its surface to move synchronously. The moving plate 53 slides in a limited manner on the support rod 45. The moving plate 53 drives the connecting rod 54 to move synchronously in the direction of the motor 51. The connecting plate 47 drives the second rack 482 to slide synchronously. The second rack 482 slides on the connecting plate 47 and meshes with the second gear 251, causing part of the scraper 25 to rotate. This scraper 25 is located between two scrapers 25 that contact the filter plate 23. After this scraper 25 rotates, the air inlet gap between the two scrapers 25 in contact with the filter plate 23 becomes smaller, reducing the flow rate of the outside air entering the interior of the cabinet 10, avoiding the problem that the electrical components vibrate due to the wind impact and the connections become loose. Although the rotation of the scraper 25 reduces the air inlet gap, it does not completely close the filter plate 23, and a certain heat dissipation capacity is still retained.

[0060] By adjusting the rotation of some of the scrapers 25 alone, the present device can adjust the size of the air inlet gap, thereby controlling the amount of air entering the cabinet 10. While ensuring heat dissipation inside the cabinet 10 and being able to drive the blade 3 to rotate, it can also avoid the problem that the electrical components inside the cabinet 10 are vibrated by excessive wind force, resulting in loose connections between the electrical components, thus ensuring the stable operation of the equipment.

[0061] Working principle: When the cabinet 10 leaks electricity during use, the current is transmitted to the surface of the cabinet 10, resulting in an imbalance in the current entering and leaving the cabinet 10. After detecting this current imbalance, the current sensor 12 converts it into an electrical signal and outputs it. Subsequently, the electrical signal is transmitted to the circuit breaker 12. The circuit breaker 12 disconnects the circuit and turns on the alarm 13. The alarm 13 emits an alarm and flashes to alert the staff.

[0062] When the external environment is sunny, the external air flow enters the interior of the cabinet 10 through the filter holes on the filter plate 23 to reduce the heat inside the cabinet 10. At this time, the scraper 25 can be set in an inclined state and attached to the surface of the filter plate 23. The external wind blows on the blade 3, causing the blade 3 to rotate and drive the rotating rod 24 to rotate synchronously. The rotating rod 24 drives several scrapers 25 to rotate synchronously. The scrapers 25 rotate and clean the impurities accumulated on the surface of the filter plate 23.

[0063] When the external humidity is relatively high or it is a rainy or cloudy day, the electric cylinder 43 can be turned on to work. The electric cylinder 43 drives the moving frame 42 to slide on the fixed rod 44. The moving frame 42 drives the support rod 45 to move in the direction of the support plate 41. The support rod 45 then drives the turntable 46 to move synchronously. The turntable 46 drives the connecting plate 47 to slide synchronously. The sliding groove inside the connecting plate 47 slides on the surface of the rotating end of the scraper 25. At the same time, the first rack 481 and the second rack 482 slide synchronously. The first rack 481, the second rack 482 and the second gear 251 are engaged, causing the scraper 25 to rotate. The surface of the scraper 25 away from the filter plate 23 rotates to be horizontal and forms a ring. One side of the scraper 25 cooperates with the protective ring 22, and the filter plate 23 can be sealed to prevent external rain and moisture from entering the interior of the cabinet 10 through the filter plate 23.

[0064] When the scraper 25 contacts the filter plate 23, the motor 51 can be turned on at this time. The motor 51 drives the lead screw 52 to rotate. The lead screw 52 drives the moving plate 53 on its surface to move synchronously. The moving plate 53 is limited to slide on the support rod 45. The moving plate 53 drives the connecting rod 54 to move synchronously in the direction of the motor 51. The connecting plate 47 drives the second rack 482 to slide synchronously. The second rack 482 slides on the connecting plate 47 and meshes with the second gear 251, causing part of the scraper 25 to rotate. This scraper 25 is between the two scrapers 25 in contact with the filter plate 23. After this scraper 25 rotates, the air inlet gap between the two scrapers 25 in contact with the filter plate 23 becomes smaller, reducing the flow rate of the external air entering the interior of the cabinet 10, avoiding the problem that the electrical components vibrate due to the wind impact and the connection becomes loose, and not completely closing the filter plate 23, still retaining a certain heat dissipation capacity and reducing the wind force.

[0065] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
