Description

Technical Field

[0001] The invention relates to the technical field of branch box heat dissipation, and in particular to a cable branch box with high-efficiency heat dissipation. Background Art

[0002] A cable branch box design with efficient heat dissipation usually involves optimizing heat dissipation performance to ensure that the equipment can maintain good temperature control during long-term operation and avoid damage to electrical components due to overheating.

[0003] The patent with the patent announcement number CN110676778B relates to a cable branch box housing with high efficiency in heat dissipation. The housing surface is connected to a cabinet door by a hinge, and a top plate is installed on the top of the housing. The patent uses a de-icing device to remove ice and snow on the top of the cable branch box, reducing the possibility of the cable branch box being crushed by snow, and extending the service life of the cable branch box; the knocking block knocks on the top plate to break the ice, which is convenient for the metal shovel to directly shovel the ice and save the energy consumption of the drive motor. On the other hand, the knocking block knocks on the top plate without causing damage to the top plate, reducing the damage of the metal shovel to the paint surface of the top plate, and extending the service life of the cable branch box; the heat inside the cable branch box is reduced by external cold water, increasing the cooling effect of the cable branch box, and extending the service life of the cable connection.

[0004] In the above patent, external cold water is used to reduce the heat inside the cable branch box, increase the cooling effect of the cable branch box, and extend the service life of the cable connection. However, in areas with large temperature differences between day and night, the large temperature difference between the inside and outside of the branch box will cause condensation beads to form inside the box. The presence of moisture inside the box will cause leakage or discharge of internal components, posing a potential danger. Summary of the invention

[0015] The present invention provides a cable branch box with high efficiency in heat dissipation. It has the following beneficial effects:

[0016] (1) In the present invention, the scraper moves and contacts the inclined plate, and the inclined plate scrapes the water droplets on the scraper surface to the inside of the water storage box. When the temperature difference between day and night is large, the scraper scrapes the water droplets generated inside the outer shell and stores them inside the water storage box, preventing the existence of moisture inside the outer shell from causing the outer shell to deteriorate in electrical insulation, preventing discharge or leakage of the device, and reducing the probability of safety accidents. The vertical plate ensures that the scraper does not contact the outer shell when it moves to the bottom, preventing the back side of the scraper from driving the water droplets to the bottom of the outer shell when the scraper moves to the bottom, so that the water droplets cannot be driven to the inside of the water storage box when the scraper moves to the top, thereby ensuring the water removal efficiency and reducing the residual water.

[0017] (2) This invention drives the top cover to rotate toward the top through the flow of internal liquid, making it easier to open the top cover. Then, the cabinet door can be manually pulled to inspect and debug the device inside the shell, thereby improving the protection of the shell while ensuring the convenience of the device when in use. The horizontal plate moves inward and blocks the scraper moving toward the bottom, making it impossible for the scraper to move toward the bottom. When the staff opens the cabinet door, the device inside the shell is limited and cannot move further, preventing the staff from being injured when inspecting and debugging the device inside the shell, thereby improving the safety of the device when in use.

[0018] (3) The invention, by moving the sealing plate toward the bottom, squeezes the air inside the inflator and discharges it through the air outlet, so that the transmission column cannot continue to rotate toward the bottom before the air is completely discharged, slowing down the speed at which the top cover rotates toward the bottom, preventing the device from being damaged due to excessive inertia when the top cover rotates toward the bottom due to the top cover being too heavy, thereby improving the protection effect of the device. By moving the sealing rod toward the bottom, the air outlet is driven to move toward the top and to the bottom of the inflator, so that the air can flow into the interior of the inflator through the air outlet, so that when the top cover is closed, it will not be affected by the buffering effect, and the top cover can be closed quickly, thereby improving the practicality of the device.

[0030] A first torsion spring is provided between the arc rod 611 and the vertical plate 610. The vertical plate 610 contacts the arc block 69, and the arc rod 611 is driven to reset by the first torsion spring.

[0031] A No. 1 spring is arranged between the rotating shaft 65 and the sliding block 64, and the scraper 66 is in contact with the inclined plate 68, and the rotating shaft 65 is driven to reset by the No. 1 spring.

[0032] When the present embodiment is working: when the detection module detects that the internal temperature of the shell 2 is too high, the exhaust fan 61 is started. The rotation of the exhaust fan 61 will discharge the hot air inside the shell 2 to the outside of the shell 2, thereby reducing the temperature inside the shell 2. When the temperature difference between day and night is large, the temperature outside is low, and the bottom of the shell 2 is high, so that the inner wall of the shell 2 is fogged and water droplets are generated. The control module starts the output end of the rotating motor 62 to rotate. The rotation of the output end of the rotating motor 62 will drive the rotating rod 63 to rotate. The rotation of the rotating rod 63 will drive the reciprocating spiral groove to rotate. The rotation of the reciprocating spiral groove will drive the slider 64 to move up and down. The slider 64 moves toward the bottom and drives the rotating shaft 65 to move toward the top. The movement of the rotating shaft 65 drives the scraper 66 to move toward the top. The scraper 66 moves toward the top and scrapes the water droplets on the inner wall of the shell 2 away from the inner wall of the shell 2 and drives the water droplets to move toward the top. The scraper 66 moves and contacts with the inclined plate 68. The inclined plate 68 scrapes the water droplets on the surface of the scraper 66 to the inside of the water storage box 67, so that When the temperature difference between day and night is large, the scraper 66 will scrape the water droplets generated inside the housing 2 and store them in the water storage box 67 to prevent the existence of moisture inside the housing 2 from causing the electrical insulation of the housing 2 to deteriorate, prevent the device from discharging or leaking electricity, and reduce the probability of safety accidents. When the scraper 66 moves to the bottom, it will contact the arc rod 611, and the arc rod 611 is blocked by the blocking arc rod 612, so that the arc rod 611 cannot rotate to the bottom. Due to the arc design of the arc rod 611 itself, the scraper 66 and the arc rod 612 are in contact with each other. When the arc rod 611 contacts, the arc rod 611 will drive the scraper 66 to move away from the inner wall of the outer shell 2. After the scraper 66 moves, it will no longer contact the outer shell 2. The vertical plate 610 will ensure that the scraper 66 will never contact the outer shell 2 when it moves toward the bottom, preventing the back side of the scraper 66 from driving the water droplets to the bottom of the outer shell 2 when the scraper 66 moves toward the bottom, causing the water droplets to be unable to be driven into the water storage box 67 when the scraper 66 moves to the top, thereby ensuring the efficiency of water removal and reducing residual moisture.

The fixing rod 76 is fixedly installed on the surface of the shell 2, and the connecting rod 77 is rotatably installed on the surface of the fixing rod 76. One end of the connecting rod 77 is rotatably installed on the bottom of the inclined block 74, and the other end of the connecting rod 77 is rotatably installed on the top of the horizontal plate 75, so as to prevent the staff from being injured when inspecting and debugging the device inside the shell 2, thereby improving the safety of the device when in use.

[0034] A No. 2 torsion spring is provided between the fixing rod 76 and the connecting rod 77. The inclined surface block 74 contacts the scraper 66, and the connecting rod 77 is driven to reset by the No. 2 torsion spring.

[0035] The buffer device includes: a support plate 81, a triangular block 82, two connecting plates 83, an inflator 84, a sealing plate 85 and a transmission column 86. The support plate 81 is fixedly mounted on the surface of the outer shell 2, the triangular block 82 is fixedly mounted between the outer shell 2 and the support plate 81, the two connecting plates 83 are fixedly mounted on a side of the top cover 78 close to the support plate 81, the inflator 84 is fixedly mounted on the top of the support plate 81, the sealing plate 85 is slidably mounted on the inner wall of the inflator 84, and an air outlet is opened on the surface of the inflator 84. One end of the transmission column 86 is fixedly mounted on the top of the sealing plate 85, and the other end of the transmission column 86 is rotatably mounted between the connecting plates 83 to prevent the device from being damaged due to excessive inertia when the top cover 78 rotates toward the bottom due to the excessive weight of the top cover 78, thereby improving the protection effect of the device.

[0036] The buffer device also includes: a sealing arc plate 87, a No. 2 spring 88 and a sealing rod 89. The sealing arc plate 87 is fixedly installed on the circumferential surface of the transmission column 86. The No. 2 spring 88 is arranged between the sealing plate 85 and the inflation cylinder 84. The sealing rod 89 slides through the inner and outer walls of the inflation cylinder 84 and the support plate 81. An air outlet is opened on the circumferential surface of the sealing rod 89. The sealing rod 89 is fixedly installed on the bottom of the sealing plate 85, so that when the top cover 78 is closed, it will not be affected by the buffer effect, and the top cover 78 can be quickly closed, thereby improving the practicality of the device.

[0037] A No. 3 torsion spring is provided between the connecting plate 83 and the transmission column 86 , and the sealing arc plate 87 is in contact with the inflator 84 , and the transmission column 86 is driven to reset by the No. 3 torsion spring.

[0038] When the present embodiment is working, the scraper 66 moves and contacts the inclined surface block 74, and the movement of the scraper 66 drives the inclined surface block 74 to move in the direction of the U-shaped rod 73. After the inclined surface block 74 moves, it no longer contacts the outer shell 2, so that the top cover 78 is no longer limited, and the top cover 78 is rotated toward the top. The rotation of the top cover 78 drives the hydraulic rod 72 to rotate toward the bottom. The rotation of the hydraulic rod 72 toward the bottom drives the top cover 78 to rotate toward the top through the internal liquid flow, so that the top cover 78 can be opened more labor-savingly, and then the cabinet door 71 is manually pulled, so that the device inside the outer shell 2 can be inspected and debugged, thereby improving the protection of the outer shell 2. To ensure the convenience of the device when in use, the movement of the inclined block 74 will drive the top of the connecting rod 77 to rotate, and the rotation of the connecting rod 77 will drive the bottom of the connecting rod 77 to rotate toward the direction of the outer shell 2. The rotation of the connecting rod 77 will drive the cross plate 75 to move toward the inside of the outer shell 2. After the cross plate 75 moves inward, it will block the scraper 66 moving toward the bottom, so that the scraper 66 cannot move to the bottom. When the staff opens the cabinet door 71, the device inside the outer shell 2 is limited and cannot continue to move, preventing the staff from being injured when repairing and debugging the device inside the outer shell 2, thereby improving the safety of the device when in use.

[0039] The top cover 78 rotates toward the bottom, which drives the connecting plate 83 to rotate toward the bottom. The connecting plate 83 rotates toward the bottom, which drives the transmission column 86 to move toward the bottom. The transmission column 86 moves toward the bottom, which drives the sealing plate 85 to move toward the bottom. The sealing plate 85 moves toward the bottom, which squeezes the air inside the inflator 84 to be discharged through the air outlet, so that the transmission column 86 cannot continue to rotate toward the bottom before the air is completely discharged, thereby slowing down the speed of the top cover 78 when it rotates toward the bottom, preventing the top cover 78 from being damaged due to excessive inertia when it rotates toward the bottom due to the overweight of the top cover 78, thereby improving the protection effect of the device. The dynamic sealing arc plate 87 moves toward the bottom, and the movement of the sealing arc plate 87 toward the bottom will block part of the air outlet holes, further ensuring the buffering effect. The movement of the sealing plate 85 toward the bottom will drive the sealing rod 89 to move toward the bottom. The movement of the sealing rod 89 toward the bottom will drive the air outlet holes to move toward the bottom and move out of the interior of the inflation tube 84. When the sealing rod 89 moves toward the bottom, it will drive the air outlet holes to move toward the top and move to the bottom of the inflation tube 84, so that air can flow to the interior of the inflation tube 84 through the air outlet holes, so that when the top cover 78 is closed, it will not be affected by the buffering effect, and the top cover 78 can be quickly closed, thereby improving the practicality of the device.
