[0004] In the above patent, the outer shell of the distribution box is made of high-strength stainless steel plate, with high strength, anti-aging, corrosion resistance, and can resist accidental or malicious damage. The inner shell of the distribution box is made of high-strength glass fiber reinforced unsaturated polyester plastic, with a long service life, anti-aging, radiation resistance, and does not require any surface protection, and can withstand drastic climate and harsh working environments. However, in seasons with lower temperatures, due to the components inside the distribution box being in a low-temperature condition for a long time, some components are affected by low temperature, resulting in material fatigue, component aging, and component damage. Summary of the Invention

[0005] To overcome the above defects, embodiments of the present invention provide an anti-aging optical cable distribution box, which solves the technical problem in the prior art that due to the components inside the distribution box being in a low-temperature condition for a long time, some components are affected by low temperature, resulting in material fatigue, component aging, and component damage.

[0006] According to one aspect, at least one embodiment of the present invention provides an anti-aging optical cable distribution box, including a floor cabinet. A housing is fixedly installed on the top of the floor cabinet. A top cover is fixedly installed on the top of the housing. A rain shield is fixedly installed on the top of the top cover. A temperature control device is provided at the bottom of the inner wall of the housing, and the temperature control device discharges hot air to control the internal temperature of the housing to maintain a constant temperature; A connecting piece is fixedly installed on the top of the top cover; A driving fan, the driving fan being fixedly mounted on an end of the connecting member away from the top cover, the driving fan being used to blow hot air floating on the top toward the bottom, and the driving fan being electrically connected to the temperature control device; The outer ring is slidably mounted on the circumferential surface of the top cover, and the inner ring is rotatably mounted on the inner wall of the circumferential surface of the outer ring; a rotating shaft is fixedly mounted on the bottom of the output end of the driving fan, and a telescopic rod is rotatably mounted on the circumferential surface of the rotating shaft, and the free end of the telescopic rod is rotatably connected to the circumferential surface of the inner ring; a cleaning brush is slidably mounted on the circumferential surface of the rotating shaft, and the other end of the cleaning brush away from the rotating shaft is fixedly mounted on the inner wall of the circumferential surface of the inner ring; the temperature control device starts the driving fan, and the blades of the driving fan rotate, blowing the hot air floating on the top to the bottom and circulating the hot air, thereby improving the temperature control effect of the device; the rotation of the blades of the driving fan will contact the cleaning brush, and the cleaning brush will clean the blades of the driving fan.

[0007] For example, in an aging-resistant optical cable junction box provided by at least one embodiment of the present invention, a detection device is provided inside the temperature control device, and the detection device is used to detect the temperature inside the outer shell. The detection device is electrically connected to the temperature control device, and a collection frame is provided at the bottom of the top cover. The top of the floor cabinet is provided with a cleaning device for scraping off residual water vapor on the inner wall of the outer shell and a protective device for protecting components arranged inside the outer shell. The movement of the outer ring drives the cleaning brush to move to the bottom and no longer contacts the blades of the driving fan.

[0008] A torsion spring No. 1 is provided between the rotating shaft and the telescopic rod. The cleaning brush contacts the blades of the driving fan. The torsion spring No. 1 drives the telescopic rod to rotate toward the top when the telescopic rod is no longer restricted by centrifugal force.

[0009] The cleaning device includes: a ring 1, two ring 2s, a gear belt, a screw, a sliding block, a water shoveling plate and a slider. A water outlet is provided on the surface of the outer shell. The ring 1 is fixedly mounted on the circumferential surface of the rotating shaft. The two ring 2s are rotatably mounted on the bottom of the inner wall of the top cover. The ring 1 and the two ring 2s are connected by a gear belt transmission. The screw rotates and passes through the inner and outer walls of the outer shell and the top cover. A reciprocating spiral groove is provided on the circumferential surface of the screw. The screw is fixedly mounted on the inner wall of the circumferential surface of the ring 2. The sliding block is slidably mounted on the inner wall of the reciprocating spiral groove. The slider is slidably mounted on the inner wall of the outer shell. One end of the water shoveling plate is rotatably mounted on the surface of the sliding block, and the other end of the water shoveling plate is rotatably mounted on the surface of the slider. The water shoveling plate moves toward the bottom to remove the water condensation beads on the inner wall of the outer shell and discharge them through the water outlet.

[0010] According to another aspect, at least one embodiment of the present invention further provides an anti-aging optical cable distribution box. The cleaning device further includes: a fixed vertical rod, an arc-shaped rotating rod, a one-way baffle, and a limiting rod. The fixed vertical rod is fixedly installed on the inner wall of the housing. The arc-shaped rotating rod is rotatably installed at the top of the fixed vertical rod. The one-way baffle is fixedly installed on the surface of the fixed vertical rod. The limiting rod is fixedly installed at one end of the water shoveling plate close to the slider. The slider is blocked by the fixed vertical rod and rotates towards the bottom again, driving the water shoveling plate to reset and fit with the inner wall of the housing again, so that when the water shoveling plate moves upwards, it will not drive the water condensate beads to the top.

[0011] A second torsion spring is arranged between the arc-shaped rotating rod and the fixed vertical rod. The limiting rod contacts the fixed vertical rod. A reset torsion spring is arranged between the sliding block and the water shoveling plate. When the slider no longer contacts the fixed vertical rod, the reset spring drives the water shoveling plate to rotate. When the water shoveling plate no longer contacts the arc-shaped rotating rod, the second torsion spring drives the arc-shaped rotating rod to rotate upwards.

[0012] For example, in an anti-aging optical cable distribution box provided by at least one embodiment of the present invention, the protection device includes: a protection door, an air inflation cylinder, a sealing plate, a transmission rod, a through sliding rod, a connecting sleeve rod, a blocking plate, and a limiting rotating rod. The protection door is rotatably installed on the surface of the housing. The air inflation cylinder is fixedly installed at the bottom of the inner wall of the top cover. The sealing plate is slidably installed in the inner wall of the air inflation cylinder. The transmission rod slidably penetrates through the inner and outer walls of the top cover and the housing. The through sliding rod is fixedly installed at the top of the sealing plate. The through sliding rod slidably penetrates through the inner and outer walls of the air inflation cylinder. The connecting sleeve rod is slidably installed on the circumferential surface of the through sliding rod. The blocking plate is fixedly installed at the bottom of the connecting sleeve rod. The limiting rotating rod is rotatably installed on the side of the protection door close to the housing. Two air outlet holes are formed in the circumferential surface of the air inflation cylinder. After the limiting rotating rod rotates, it no longer limits the protection door. The movement of the connecting sleeve rod drives the blocking plate to move downwards. The movement of the blocking plate will block some of the air outlet holes, so that when the through sliding rod moves downwards, it can only move slowly.

[0013] A spring is arranged between the sealing plate and the air inflation cylinder. The top of the circumferential surface of the through sliding rod is polished. The spring drives the sealing plate to move upwards.

[0014] The beneficial effects of the embodiments of the present invention are as follows: In the present invention, when the detection device detects that the internal temperature of the housing is relatively low, the detection device activates the temperature control device. The temperature control device starts and blows hot air towards the inner wall of the housing, raising the temperature inside the housing, ensuring that the components inside the device are at an optimal constant temperature, preventing the device from being damaged due to frostbite caused by low temperature, which leads to material aging, improving the anti-aging property of the device, and extending its service life. When the temperature control device is activated, the driving fan is also activated, and the fan blades of the driving fan rotate, blowing the hot air floating at the top towards the bottom and making the hot air circulate, improving the temperature control effect of the device. When the fan blades of the driving fan rotate, they will come into contact with the cleaning brush. The cleaning brush will clean the fan blades of the driving fan, and the static electricity generated by the rotation will adsorb the swept impurities inside the collection box, preventing the accumulation of impurities on the surface of the fan blades after long-term use, which may lead to ineffective air circulation inside the housing, and improving the practicality of the device.

[0015] In the present invention, the outer ring moves to drive the cleaning brush to move downwards and no longer contact the fan blades of the driving fan, preventing the high-speed rotating fan blades from hitting the cleaning brush and improving the protection effect on the device. When the water scraping plate moves downwards, it will scrape off the water condensate beads on the inner wall of the housing and discharge them through the water outlet, preventing the excessive water condensate beads from causing too high humidity inside the housing, which may affect the normal operation of the internal components and improving the stability of the device when working in a low-temperature environment.

[0016] In the present invention, the slider is blocked by the fixed vertical rod and rotates downwards again, driving the water scraping plate to reset and fit the inner wall of the housing again, so that when the water scraping plate moves upwards, it will not drive the water condensate beads to the top, preventing some water from being blocked by the water scraping plate all the time and unable to be discharged through the water outlet holes, and improving the practicality of the device.

[0017] In the present invention, after the limit rotating rod rotates, it no longer limits the protective door, so that the device can be opened and inspected when the cleaning device stops working, ensuring the safety of the staff during work. When the connecting sleeve rod moves, it drives the blocking plate to move downwards. The movement of the blocking plate will block some of the air outlet holes, so that when the through sliding rod moves downwards, it can only move slowly, allowing the water scraping plate to have sufficient time to exhaust the device again, reducing the probability of accidents.

[0025] As Figures 1 to 8 shown, it shows an anti-aging optical cable cross-connect box in an embodiment of the present invention, including a floor cabinet 1, a housing 2 is fixedly installed on the top of the floor cabinet 1, a top cover 3 is fixedly installed on the top of the housing 2, and a rain shield 4 is fixedly installed on the top of the top cover 3; A temperature control device 5, the temperature control device 5 is arranged at the bottom of the inner wall of the housing 2, the temperature control device 5 discharges hot air, is used to control the internal temperature of the housing 2 to remain constant, ensure that the components inside the device are at the best constant temperature, prevent the device from being frostbitten due to low temperature, resulting in material aging and damage, improve the anti-aging property of the device, and the service life; A connecting member 61 is fixedly installed on the top of the top cover 3; A driving fan 62, the driving fan 62 is fixedly installed at one end of the connecting member 61 away from the top cover 3, the driving fan 62 is used to blow the hot air floating on the top to the bottom, and the driving fan 62 is electrically connected to the temperature control device 5; The circumferential surface of the top cover 3 is slidably mounted with an outer ring 63. The inner wall of the circumferential surface of the outer ring 63 is rotatably mounted with an inner ring 64. The bottom of the output end of the driving fan 62 is fixedly mounted with a rotating shaft 65. The circumferential surface of the rotating shaft 65 is rotatably mounted with a telescopic rod 66. The free end of the telescopic rod 66 is rotatably connected to the circumferential surface of the inner ring 64. The circumferential surface of the rotating shaft 65 is slidably mounted with a cleaning brush 67. The other end of the cleaning brush 67 away from the rotating shaft 65 is fixedly mounted on the inner wall of the circumferential surface of the inner ring 64, and adsorbs the swept impurities inside the collection box through the static electricity generated by rotation, preventing the accumulation of impurities on the surface of the fan blades due to long-term use, which may cause the inability to effectively drive the air circulation inside the housing 2, and improving the practicability of the device.

[0026] In some examples, a detection device is provided inside the temperature control device 5. The detection device is used to detect the temperature inside the housing 2. The detection device is electrically connected to the temperature control device 5. A collection box is provided at the bottom of the top cover 3 to prevent the high-speed rotating fan blades from hitting the cleaning brush 67 and improving the protection effect on the device.

[0027] A first torsion spring is provided between the rotating shaft 65 and the telescopic rod 66. The cleaning brush 67 contacts the fan blades of the driving fan 62, and drives the telescopic rod 66 to rotate upward through the first torsion spring when the telescopic rod 66 is no longer restricted by the centrifugal force.

[0028] For example, as Figures 1 to 8As shown, when in a low-temperature environment and the detection device detects that the internal temperature of the outer shell 2 is relatively low, the detection device activates the temperature control device 5. The temperature control device 5 starts and blows hot air towards the inner wall of the outer shell 2, raising the temperature inside the outer shell 2, ensuring that the components inside the device are at an optimal constant temperature, preventing the device from being damaged due to frostbite caused by low temperature, which may lead to material aging, improving the anti-aging property of the device and its service life. The temperature control device 5 activates the driving fan 62, and the fan blades of the driving fan 62 rotate, blowing the hot air floating at the top towards the bottom and making the hot air circulate, improving the temperature control effect of the device. When the fan blades of the driving fan 62 rotate, they will contact the cleaning brush 67. The cleaning brush 67 will clean the fan blades of the driving fan 62 and adsorb the swept impurities inside the collection box through the static electricity generated by rotation, preventing the accumulation of impurities on the surface of the fan blades after long-term use, which may cause the inability to effectively drive the air circulation inside the outer shell 2 and improving the practicality of the device. The rotation of the driving fan 62 drives the rotation of the rotating shaft 65, the rotation of the rotating shaft 65 drives the rotation of the telescopic rod 66, the rotation of the telescopic rod 66 drives the rotation of the inner ring 64. When the telescopic rod 66 reaches a sufficient rotation speed, due to the influence of centrifugal force, the telescopic rod 66 rotates towards the bottom. The telescopic rod 66 rotating towards the bottom drives the inner ring 64 to move towards the bottom. The movement of the inner ring 64 drives the outer ring 63 to move towards the bottom. The movement of the outer ring 63 drives the cleaning brush 67 to move towards the bottom and no longer contact the fan blades of the driving fan 62, preventing the high-speed rotating fan blades from damaging the cleaning brush 67 and improving the protection effect on the device.

[0029] As Figures 1 to 8 shown, it shows another embodiment of the present invention. A cleaning device for scraping off the residual water vapor on the inner wall of the outer shell 2 and a protection device for protecting the components arranged inside the outer shell 2 are provided on the top of the floor cabinet 1. Among them, the cleaning device includes: a first collar 71, two second collars 72, a gear belt 73, a lead screw 74, a sliding block 75, a water scraping plate 76 and a slider 77. A water outlet is provided on the surface of the outer shell 2. The first collar 71 is fixedly installed on the circumferential surface of the rotating shaft 65. Both of the two second collars 72 are rotatably installed at the bottom of the inner wall of the top cover 3. The first collar 71 and the two second collars 72 are connected by a gear belt 73. The lead screw 74 rotates through the inner and outer walls of the outer shell 2 and the top cover 3. A reciprocating spiral groove is provided on the circumferential surface of the lead screw 74. The lead screw 74 is fixedly installed on the inner wall of the circumferential surface of the second collar 72. The sliding block 75 is slidably installed on the inner wall of the reciprocating spiral groove. The slider 77 is slidably installed on the inner wall of the outer shell 2. One end of the water scraping plate 76 is rotatably installed on the surface of the sliding block 75, and the other end of the water scraping plate 76 is rotatably installed on the surface of the slider 77, preventing excessive water condensation beads from causing too high humidity inside the outer shell 2 and affecting the normal operation of the internal components, and improving the stability of the device when working in a low-temperature environment.

[0030] The cleaning device further includes: a fixed vertical rod 78, an arc-shaped rotating rod 79, a one-way baffle 710, and a limiting rod 711. The fixed vertical rod 78 is fixedly installed on the inner wall of the housing 2. The arc-shaped rotating rod 79 is rotatably installed on the top of the fixed vertical rod 78. The one-way baffle 710 is fixedly installed on the surface of the fixed vertical rod 78. The limiting rod 711 is fixedly installed at one end of the water shoveling plate 76 close to the slider 77, preventing some moisture from being blocked by the water shoveling plate 76 all the time and unable to be discharged through the water outlet holes, thus improving the practicability of the device. In some examples, a second torsion spring is provided between the arc-shaped rotating rod 79 and the fixed vertical rod 78. The limiting rod 711 contacts the fixed vertical rod 78. A return torsion spring is provided between the sliding block 75 and the water shoveling plate 76. When the slider 77 no longer contacts the fixed vertical rod 78, the return spring drives the water shoveling plate 76 to rotate. When the water shoveling plate 76 no longer contacts the arc-shaped rotating rod 79, the second torsion spring drives the arc-shaped rotating rod 79 to rotate upward.

[0031] The protection device includes: a protection door 81, an air inflation cylinder 82, a sealing plate 83, a transmission rod 84, a penetrating slide rod 85, a connecting sleeve rod 86, a blocking plate 87, and a limiting rotating rod 88. The protection door 81 is rotatably installed on the surface of the housing 2. The air inflation cylinder 82 is fixedly installed at the bottom of the inner wall of the top cover 3. The sealing plate 83 is slidably installed in the inner wall of the air inflation cylinder 82. The transmission rod 84 slidably penetrates through the inner and outer walls of the top cover 3 and the housing 2. The penetrating slide rod 85 is fixedly installed on the top of the sealing plate 83. The penetrating slide rod 85 slidably penetrates through the inner and outer walls of the air inflation cylinder 82. The connecting sleeve rod 86 is slidably installed on the circumferential surface of the penetrating slide rod 85. The blocking plate 87 is fixedly installed at the bottom of the connecting sleeve rod 86. The limiting rotating rod 88 is rotatably installed on the side of the protection door 81 close to the housing 2. Two air outlet holes are provided on the circumferential surface of the air inflation cylinder 82, so that the device can be opened and inspected when the cleaning device stops working, ensuring the safety of the staff during work, enabling the water shoveling plate 76 to have sufficient time to exhaust the device again, and reducing the probability of accidents.

[0032] A spring is provided between the sealing plate 83 and the air inflation cylinder 82. The top of the circumferential surface of the penetrating slide rod 85 is polished, and the spring drives the sealing plate 83 to move upward.

[0033] For example, as Figures 1 to 8As shown, due to the too low external temperature, after a temperature difference is generated between the inside and the outside of the outer shell 2, water condensation beads are generated on the inner wall of the outer shell 2. The rotation of the rotating shaft 65 drives the rotation of the first collar 71. The rotation of the first collar 71 drives the rotation of the second collar 72 through the gear belt 73. The rotation of the second collar 72 drives the rotation of the lead screw 74. The rotation of the lead screw 74 drives the rotation of the reciprocating spiral groove. The rotation of the reciprocating spiral groove drives the up-and-down reciprocating movement of the sliding block 75. The movement of the sliding block 75 towards the bottom drives the water scraping plate 76 to move towards the bottom. The movement of the water scraping plate 76 towards the bottom will scrape off the water condensation beads on the inner wall of the outer shell 2 and discharge them through the water outlet, preventing the excessive water condensation beads from causing too high humidity inside the outer shell 2 and affecting the normal operation of the internal components, and improving the stability of the device when working in a low-temperature environment. The movement of the water scraping plate 76 drives the slider 77 to move towards the bottom. After the slider 77 moves to the bottommost position, it no longer contacts the fixed vertical rod 78. The water scraping plate 76 is driven to rotate by the reset torsion spring. After the water scraping plate 76 rotates, it no longer contacts the inner wall of the outer shell 2. When the water scraping plate 76 moves to the topmost position and then moves towards the bottom again, it will contact the arc-shaped rotating rod 79 at the same time. The arc-shaped rotating rod 79 is blocked by the one-way baffle 710, so that the arc-shaped rotating rod 79 cannot rotate towards the bottom, so that the slider 77 is blocked by the fixed vertical rod 78 and rotates towards the bottom again, and drives the water scraping plate 76 to reset and fit the inner wall of the outer shell 2 again, so that when the water scraping plate 76 moves towards the top, it will not drive the water condensation beads to the top, preventing some moisture from being blocked by the water scraping plate 76 all the time and unable to be discharged through the water outlet holes, and improving the practicability of the device.

[0034] When the water scraping plate 76 moves towards the top, it will contact the transmission rod 84 and drive the transmission rod 84 to move towards the top. The movement of the transmission rod 84 drives the sealing plate 83 to move towards the top. The movement of the sealing plate 83 will squeeze the air inside the inflatable cylinder 82 to be discharged through the air outlet holes. After the water scraping plate 76 no longer contacts the transmission rod 84, the sealing plate 83 moves towards the bottom by the spring reset. The movement of the sealing plate 83 drives the through sliding rod 85 to move towards the bottom. The movement of the through sliding rod 85 towards the bottom will disengage from the limit rotating rod 88 and drive the limit rotating rod 88 to rotate. After the limit rotating rod 88 rotates, it no longer limits the protective door 81, so that the device can be opened and inspected when the cleaning device stops working, ensuring the safety of the staff during work. The movement of the through sliding rod 85 drives the connecting sleeve rod 86 to move towards the bottom. The movement of the connecting sleeve rod 86 drives the blocking plate 87 to move towards the bottom. The movement of the blocking plate 87 will block some of the air outlet holes, so that when the through sliding rod 85 moves towards the bottom, it can only move slowly, so that the water scraping plate 76 has sufficient time to exhaust the device again, reducing the probability of accidents.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
