Description
A double-layer hollow grid-type JP cabinet Technical Field
[0001] This application relates to the technical field of JP cabinets, and in particular to a JP cabinet with a double-layer hollow fence structure. Background Technology
[0002] A JP switch is an integrated power distribution device that combines multiple functions such as power distribution, metering, protection, control, and reactive power compensation. It is usually installed on the low-voltage side of a distribution transformer or at an outdoor power distribution point. JP switches are widely used in various power grids.
[0003] In the relevant technology, the JP cabinet includes a cabinet body and a cabinet door. The cabinet body has a placement slot for placing power supply components. An isolation plate is provided on the outside of the cabinet body. An isolation cavity is provided on the isolation plate. A first heat dissipation hole is provided on the isolation plate to connect the isolation cavity. A second heat dissipation hole is provided on the cabinet body to connect the placement slot and the isolation cavity. A fan is provided in the isolation cavity. The fan is used to draw air from the outside into the isolation plate.
[0004] Since some JP cabinets are located outdoors, when it rains, the fan will draw rainwater directly into the second heat dissipation hole, resulting in high humidity inside the JP cabinet and affecting the normal use of the electrical components placed in the slot. Summary of the Invention
[0005] To address the issue that the fan might draw rainwater into the second heat dissipation hole, this application provides a JP cabinet with a double-layer hollow grid structure.
[0006] This application provides a double-layer hollow fence-type JP cabinet, which adopts the following technical solution: A double-layer hollow fence-type JP cabinet includes a cabinet body, a placement slot on the cabinet body, an isolation plate on the outside of the cabinet body, an isolation cavity on the isolation plate, a first heat dissipation hole on the isolation plate communicating with the isolation cavity, a first fixing hole on the cabinet body for a cable to pass through, the first fixing hole communicating with the isolation cavity and the placement slot, a waterproof ring on the first fixing hole, the waterproof ring being fitted onto the cable, and the waterproof ring abutting against the inner wall of the first fixing hole.
[0007] By adopting the above technical solution, the waterproof ring is fitted onto the cable and abuts against the inner wall of the first fixing hole, which restricts moisture from directly entering the placement groove from the direction of the first fixing hole, reducing the possibility of moisture directly entering the placement groove from the first fixing hole, and making it difficult for external moisture to directly enter the placement groove.
[0008] Optionally, a first fan is provided inside the isolation chamber, and a baffle is provided inside the isolation chamber, the baffle being used to drive air to flow in the direction of the first fixed hole.
[0009] By adopting the above technical solution, when the first fan draws outside air directly into the isolation chamber, the baffle drives the air to flow in the direction of the first fixed hole, so that the air can flow quickly and stably in the direction of the first fixed hole, further increasing the air flow speed in the placement tank and improving the heat dissipation efficiency in the placement tank.
[0010] Optionally, the cabinet is provided with an elastic sheet located on the side of the waterproof ring near the baffle, and the elastic sheet can deform in the direction of the waterproof ring.
[0011] By adopting the above technical solution, when the first fan blows air, the air flows in the direction of the first fixed hole. The air can squeeze the elastic sheet located on the side of the waterproof ring near the baffle. In addition, the elastic sheet can deform in the direction of the waterproof ring. Under high wind speed, the air can squeeze the elastic sheet, allowing the elastic sheet to further squeeze the waterproof ring, so that the waterproof ring can more stably restrict the moisture in the air from passing through the first fixed hole.
[0012] Optionally, the bottom of the cabinet is provided with a second heat dissipation hole that connects to the placement slot, the cabinet is provided with a second fan, the cabinet is provided with a support base, the support base is provided with a support cavity, and the support base is provided with a flow hole that connects to the support cavity. The second fan is used to drive air to pass through the flow hole, the support cavity, and the second heat dissipation hole in sequence.
[0013] By adopting the above technical solution, the second fan is started, and the second fan drives the air to pass through the flow hole, the support cavity and the second heat dissipation hole in sequence, so that the outside air can enter the placement slot from the bottom of the cabinet. This allows the outside cold air to enter the cabinet smoothly. Since hot air will flow upward, the cold air enters the placement slot from the bottom of the cabinet in the same direction as the rising hot air, thereby accelerating the air flow rate and allowing the hot air in the cabinet to flow more smoothly in the placement slot.
[0014] Optionally, a dustproof screen is provided on the flow hole, and the second fan is used to drive air to blow forward in sequence through the flow hole, the support cavity and the second heat dissipation hole, or to drive air to blow backward in sequence through the second heat dissipation hole, the support cavity and the flow hole.
[0015] By adopting the above technical solution, when the second fan drives air to blow forward through the flow hole, support cavity, and second heat dissipation hole in sequence, the airflow direction in the placement tank is from bottom to top, allowing the air in the placement tank to flow in accordance with the natural airflow direction and accelerating the airflow rate. When the second fan drives air to blow backward through the second heat dissipation hole, support cavity, and flow hole in sequence, the airflow direction in the placement tank is from top to bottom, allowing the air in the placement tank to break through the heat layer at the top of the placement tank, resulting in a more uniform temperature distribution in the placement tank and preventing excessive heat accumulation at the top of the placement tank that is difficult to dissipate. At the same time, during the backward blowing, air can be blown out from the flow hole, creating positive pressure inside the support cavity, making it difficult for external rainwater to directly enter the flow hole, reducing the possibility of external rainwater directly intruding into the support cavity, and enabling the support base to achieve a waterproof effect. Simultaneously, during the backward blowing, because the flow hole is equipped with a dustproof net, the air can be blown directly on the dustproof net, allowing the dust accumulated on the dustproof net to be removed, achieving a dustproof effect.
[0016] Optionally, the cabinet is equipped with a humidity controller, which is electrically connected to the second fan. The humidity controller is used to control the second fan to blow forward or backward. When the humidity controller detects that the humidity is too high, the second fan blows backward; when the humidity controller detects that the humidity is normal, the second fan blows forward.
[0017] By adopting the above technical solution, the humidity controller is electrically connected to the second fan and is installed inside the cabinet. This allows the humidity controller to detect the humidity inside the placement slot and control the second fan to blow forward and backward to control the humidity inside the placement slot. The second fan blows backward to prevent air from entering the placement slot from below the cabinet, thereby reducing the amount of rainwater entering the cabinet.
[0018] Optionally, a second fixing hole is provided on the cabinet body. The second fixing hole is located on the side of the first heat dissipation hole away from the first fixing hole. A support rod is provided in the isolation cavity. The baffle is rotatably connected to the support rod. The baffle is used to drive air to flow in the direction of the first fixing hole or the second fixing hole.
[0019] By adopting the above technical solution, the baffle is rotatably connected to the support rod, allowing the baffle to rotate in the direction of the first or second fixed hole, so that the baffle can drive the air to flow in the direction of the first or second fixed hole; when the second fan blows back, the second fixed hole is located on the side of the first heat dissipation hole away from the first fixed hole, so that the air at the first fan can flow from top to bottom, allowing the air to flow fully in the placement slot, further increasing the heat dissipation efficiency.
[0020] Optionally, a driving component is provided inside the isolation chamber, and the humidity controller is electrically connected to the driving component. The driving component is used to drive the baffle to rotate. When the humidity controller detects that the humidity is high, the baffle tilts towards the direction of the second fixing hole. When the humidity controller detects that the humidity is normal, the baffle tilts towards the direction of the first fixing hole.
[0021] By adopting the above technical solution, the humidity controller is electrically connected to the drive unit, allowing the humidity controller to control whether the drive unit is started, so that the drive unit can drive the baffle to rotate, allowing the baffle to tilt smoothly in the direction of the second fixing hole or the first fixing hole, so that the staff does not need to make manual adjustments.
[0022] In summary, this application includes at least one of the following beneficial technical effects: by fitting a waterproof ring onto the cable and abutting against the inner wall of the first fixing hole, the waterproof ring can restrict moisture from directly entering the placement groove from the direction of the first fixing hole, reducing the possibility of moisture directly entering the placement groove from the first fixing hole, making it difficult for external moisture to directly enter the placement groove.
[0023] When the second fan drives air to blow forward through the flow hole, support cavity, and second heat dissipation hole in sequence, the airflow direction in the placement tank is from bottom to top, allowing the air in the placement tank to flow in accordance with the natural airflow direction and accelerating the airflow rate. When the second fan drives air to blow backward through the second heat dissipation hole, support cavity, and flow hole in sequence, the airflow direction in the placement tank is from top to bottom, allowing the air in the placement tank to break through the heat layer at the top of the placement tank, resulting in a more uniform temperature distribution and preventing excessive heat accumulation at the top of the placement tank that is difficult to dissipate. At the same time, during the backward blowing, air can be blown out from the flow hole, creating positive pressure inside the support cavity, making it difficult for external rainwater to directly enter the flow hole, reducing the possibility of external rainwater directly intruding into the support cavity, thus achieving a waterproof effect for the support base. Simultaneously, during the backward blowing, because there is a dustproof net on the flow hole, the air can be blown directly on the dustproof net, allowing the dust accumulated on the dustproof net to be removed, achieving a dustproof effect.

[0026] The present application will be further described in detail below with reference to Figures 1-4.
[0027] This embodiment discloses a JP cabinet with a double-layer hollow fence structure. Referring to Figures 1 and 2, a JP cabinet with a double-layer hollow fence structure includes a cabinet body 1 and a cabinet door 11. The cabinet body 1 has a placement slot 12, in which electrical components are placed.
[0028] Referring to Figures 1 and 2, a mounting plate 2 is provided on the top of the cabinet 1, and mounting holes 21 are provided on the side of the mounting plate 2. A through hole 13 is provided on the top of the cabinet 1, and the through hole 13 connects the mounting hole 21 and the placement groove 12. The mounting hole 21 and the through hole 13 allow for gas exchange inside the cabinet 1.
[0029] Referring to Figure 2, an isolation plate 3 is fixedly connected to the outer surface of the cabinet 1. An isolation cavity 31 is formed on the surface of the isolation plate 3 near the cabinet 1. A first heat dissipation hole 32 is formed on the outer surface of the isolation plate 3, and the first heat dissipation hole 32 connects to the isolation cavity 31. A first fixing hole 14 is formed on the side of the cabinet 1, and the first fixing hole 14 connects to the placement slot 12 and the isolation cavity 31. The first fixing hole 14 allows cables to pass through, and the first fixing hole 14 extends to the side of the isolation plate 3 away from the cabinet 1.
[0030] Referring to Figure 2, the first fixing hole 14 allows the cable to pass through, and a waterproof ring 141 is fitted onto the cable. The waterproof ring 141 can restrict the passage of moisture and can abut against the inner wall of the first fixing hole 14. A first fan 33 is fixedly connected to the inner wall of the isolation chamber 31. The first fan 33 is located at the first heat dissipation hole 32 and drives outside air to be drawn into the isolation chamber 31.
[0031] Referring to Figure 2, a second fixing hole 142 is provided on the side of the cabinet 1. The second fixing hole 142 connects the placement slot 12 and the isolation cavity 31. The second fixing hole 142 is located on the side of the first heat dissipation hole 32 away from the first fixing hole 14. The second fixing hole 142 allows the cable to pass through, and the second fixing hole 142 extends to the side of the isolation plate 3 away from the cabinet 1.
[0032] Referring to Figures 2 and 3, a support rod 34 is fixedly connected inside the isolation chamber 31, and a baffle 341 is rotatably connected to the support rod 34. The baffle 341 is located on the side of the first fan 33 near the placement slot 12, and the baffle 341 can tilt towards the first fixing hole 14 or the second fixing hole 142. A driving component 35 is fixedly connected inside the isolation chamber 31. The driving component 35 includes a driving cylinder, and the driving shaft of the driving cylinder is rotatably connected to one end of the baffle 341. The driving cylinder drives the baffle 341 to rotate, allowing the baffle 341 to tilt towards the first fixing hole 14 or towards the second fixing hole 142, thereby concentrating the air flow towards the first fixing hole 14 or the second fixing hole 142.
[0033] Referring to Figure 2, two elastic sheets 143 are fixedly connected to the outer surface of the cabinet 1, and the two elastic sheets 143 are located on the upper and lower sides of the first fan 33, respectively. The elastic sheets 143 are located on the side of the waterproof ring 141 closer to the first fan 33, and the elastic sheets 143 can deform in a direction away from the first fan 33. When the airflow velocity at the first fan 33 increases, the elastic sheets 143 can compress the waterproof ring 141, making the connection between the waterproof ring 141 and the cable more compact and reducing the possibility of moisture passing through the waterproof ring 141.
[0034] Referring to Figures 2 and 4, a second heat dissipation hole 15 is provided on the bottom of the cabinet 1, and the second heat dissipation hole 15 is connected to the placement groove 12. A support base 4 is fixedly connected to the bottom of the cabinet 1. A support cavity 41 is provided on the support base 4, and the support cavity 41 is connected to the second heat dissipation hole 15. A second fan 42 is fixedly connected inside the support cavity 41. An airflow hole 43 is provided on the outer surface of the support base 4, and the airflow hole 43 is connected to the support cavity 41. A dustproof net 44 is also fixedly connected to the outer surface of the support base 4. The dustproof net 44 is located outside the airflow hole 43 and is used to prevent dust from entering the airflow hole 43.
[0035] Referring to Figures 2 and 4, when the second fan 42 blows air in the forward direction, it drives the air to pass sequentially through the flow hole 43, the support cavity 41, and the second heat dissipation hole 15. When the second fan 42 blows air in the reverse direction, it drives the air to pass sequentially through the second heat dissipation hole 15, the support cavity 41, and the flow hole 43.
[0036] Referring to Figures 2, 3, and 4, a humidity controller 16 is fixedly connected inside the cabinet 1. The humidity controller 16 is electrically connected to the second fan 42 and the drive cylinder. The humidity controller 16 is used to detect the humidity in the placement slot 12, and to control the second fan 42 to blow forward or backward, and to determine whether the drive cylinder is activated.
[0037] Referring to Figures 2, 3, and 4, when the humidity controller 16 detects that the humidity in the placement tank 12 is high, the humidity controller 16 controls the drive cylinder to start, causing the drive cylinder to rotate the baffle 341. The baffle 341 can tilt towards the direction of the second heat dissipation hole 15, so that the air blown by the first fan 33 can flow smoothly towards the direction of the second heat dissipation hole 15. At the same time, the humidity controller 16 controls the second fan 42 to back-blow, so that the air blown by the second fan 42 passes through the second heat dissipation hole 15, the support cavity 41, and the flow hole 43 in sequence, so that the air can clean the dust on the dustproof net 44, prevent rainwater from directly entering the support cavity 41 from the direction of the flow hole 43, and at the same time break the temperature distribution in the placement tank 12.
[0038] Referring to Figures 2, 3, and 4, when the humidity controller 16 detects that the humidity in the placement tank 12 is normal, the humidity controller 16 is not activated. At this time, the baffle 341 is tilted towards the first heat dissipation hole 32; and the second fan 42 blows air in the forward direction, allowing the air blown by the second fan 42 to pass through the flow hole 43, the support cavity 41, and the second heat dissipation hole 15 in sequence, so that the air flow in the placement tank 12 follows the natural rising of hot air, thereby accelerating the air flow rate in the placement tank 12.
[0039] The implementation principle of a double-layer hollow grid-type JP cabinet in this application embodiment is as follows: When the humidity controller 16 detects that the humidity in the placement slot 12 is high, the humidity controller 16 controls the drive cylinder to start, so that the drive cylinder drives the baffle 341 to rotate. The baffle 341 can tilt towards the direction of the second heat dissipation hole 15, so that the air blown by the first fan 33 can flow smoothly towards the direction of the second heat dissipation hole 15. At the same time, the humidity controller 16 controls the second fan 42 to back-blow, so that the air blown by the second fan 42 passes through the second heat dissipation hole 15, the support cavity 41 and the flow hole 43 in sequence, so that the air can clean the dust on the dustproof net 44, prevent rainwater from directly entering the support cavity 41 from the direction of the flow hole 43, and at the same time break the temperature distribution in the placement slot 12.
