Description

Technical Field

[0001] This invention relates to the field of optical cable junction box technology, and in particular to an optical cable junction box with integrated environmental monitoring. Background Technology

[0002] An optical fiber junction box is a type of junction device that provides termination and patching for backbone optical cables and distribution layer optical cables. Optical fiber junction devices generate a large amount of heat during operation, therefore requiring a specialized heat dissipation structure inside the junction box. For example, Chinese patent CN117687163A discloses a heat dissipation component for an outdoor optical fiber junction box. Since optical fiber junction boxes are often installed outdoors, they are susceptible to rain in open-air environments, necessitating waterproof protection. For instance, Chinese patent CN117555097A discloses a high-security communication optical fiber junction box. Existing junction boxes mostly rely on ventilation for internal heat dissipation, but this method easily introduces moisture from the air into the junction box during rainy weather, potentially causing short circuits in the optical fiber junction device. Summary of the Invention

[0003] The core of this invention lies in solving the problem in the prior art where the optical cable junction equipment inside the junction box is easily affected by moisture during the ventilation and heat dissipation process by adjusting the heat dissipation method of the junction box based on environmental monitoring results.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] An integrated environmental monitoring optical cable junction box includes a box body and optical cable junction modules disposed at the left and right ends inside the box body. A fan chamber is fixedly connected to the bottom of the box body, and a cold air chamber is fixedly connected between the two optical cable junction modules. The bottom end of the cold air chamber is connected to the fan chamber, and a heat transfer grid is fixedly connected between the outside of the cold air chamber and the optical cable junction modules. The top end of the cold air chamber is connected to the top end of the box body. The cold air chamber has cold air holes arranged in a matrix at both ends. The cold air holes are inclined and the top of the cold air holes face the optical cable junction module. A guide plate is fixedly connected to the upper part of the bottom of the cold air holes. A lifting bracket is movably connected inside the cold air chamber. Multiple parallel closed plates are fixedly connected to both ends of the lifting bracket. The closed plates are slidably connected to the bottom of the cold air holes, and the top of the closed plates is in contact with the bottom of the guide plate. The optical cable junction module includes an environmental monitoring module. The input end of the environmental monitoring module is connected to a temperature sensor and a humidity sensor. The bottom of the cold air chamber is fixedly connected to a lifting mechanism for driving the lifting support. The output end of the environmental monitoring module is connected to the opening and closing end of the lifting mechanism.

[0006] Furthermore, a herringbone plate is fixedly connected to the middle of the fan chamber, and the herringbone plate is vertically aligned with the bottom of the cold air chamber. Cooling fans are fixedly connected to both the left and right ends of the herringbone plate.

[0007] Furthermore, the lifting mechanism consists of a threaded shaft rotatably connected to the cold air chamber and a linkage bracket externally threaded to the threaded shaft. The top of the linkage bracket is hinged to the lifting bracket, and the bottom of the linkage bracket is hinged to the top of the herringbone plate. A drive motor is fixedly connected to the bottom of the optical cable junction module, and the output end of the drive motor is fixedly connected to the threaded shaft.

[0008] Preferably, a rainwater funnel is fixedly connected to the top of the housing, the bottom of the rainwater funnel is fixedly connected to the top of the cold air chamber, and a top cover is fixedly connected to the top of the lifting bracket, which is engaged with the top of the rainwater funnel.

[0009] Furthermore, the top of the guide eaves is curved to form a water collection trough, and end diaphragms are fixedly connected to both ends of the water collection trough. The end of the end diaphragm away from the water collection trough is fixedly connected to the lifting bracket.

[0010] Furthermore, an overflow hole is provided at the end of the water collection tank near the cold air chamber, and the bottom height of the overflow hole is less than the height of the end of the water collection tank away from the cold air chamber.

[0011] Furthermore, a seepage plug is fixedly inserted into the bottom of the overflow hole. The seepage plug is T-shaped and its bottom is in close contact with the surface of the cold air chamber. The seepage plug is made of sponge material. A sliding groove is opened at the end of the sealing plate near the cold air chamber, which is slidably connected to the seepage plug.

[0012] Compared with the prior art, the advantages of this invention are: (1) The present invention monitors the environment of the optical cable junction box through an environmental monitoring module and adjusts the opening and closing of the cold air hole according to the environmental monitoring results. In sunny weather, the cold air moving from bottom to top in the cold air chamber blows from the cold air hole to the optical cable junction module to cool the optical cable junction module. In rainy weather, the lifting bracket drives the sealing plate to rise and close the cold air hole. Heat is transferred and cooled through the cold air chamber and the optical cable junction modules at both ends, effectively preventing the cold air with high humidity from contacting the optical cable junction module, thereby effectively preventing the optical cable junction module from short-circuiting due to moisture.

[0013] (2) The invention opens the top cover by lifting the lifting bracket, and uses the rainwater funnel to send the collected rainwater into the cold air chamber, so that the rainwater wets the inner wall of the cold air chamber. Then, the cold air moving upward in the cold air chamber accelerates the evaporation of the rainwater, thereby realizing the water cooling heat dissipation of the optical cable junction module inside the box by the cold air chamber.

[0016] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0017] First implementation method: Please see Figures 1 to 3An integrated environmental monitoring fiber optic junction box includes a box body 1 and fiber optic junction modules 101 disposed at the left and right ends inside the box body 1. A fan chamber 102 is fixedly connected to the bottom of the box body 1. A cold air chamber 103 is fixedly connected between the two fiber optic junction modules 101. The bottom end of the cold air chamber 103 communicates with the fan chamber 102, and a heat transfer grid 104 is fixedly connected between the outside of the cold air chamber 103 and the fiber optic junction modules 101. Heat transfer and heat dissipation are achieved by rapidly flowing cold air in the cold air chamber 103 to the fiber optic junction modules 101 at the left and right ends of the cold air chamber 103. The heat transfer area is increased by using the heat transfer grid 104, thereby effectively improving the heat dissipation effect on the optical cable junction module 101. The top of the cold air chamber 103 is connected to the top of the housing 1. A herringbone plate 105 is fixedly connected to the middle of the fan chamber 102. The herringbone plate 105 is vertically corresponding to the bottom of the cold air chamber 103. Cooling fans 106 are fixedly connected to both the left and right ends of the herringbone plate 105. The cold air driven by the cooling fans 106 is guided by the herringbone plate 105 to turn and enter the cold air chamber 103, which facilitates the upward flow of cold air in the cold air chamber 103. When the optical cable junction box is cooled, the cold air driven by the cooling fan 106 is guided and turned by the herringbone plate 105 into the cold air chamber 103. The cold air flows rapidly from bottom to top in the cold air chamber 103, and performs heat transfer and cooling on the optical cable junction modules 101 at both ends of the cold air chamber 103. The heat transfer grid 104 increases the heat transfer area, thereby effectively improving the heat dissipation effect on the optical cable junction module 101.

[0018] Please see Figures 3 to 5 The cold air chamber 103 has cold air holes 2 arranged in a matrix at both its left and right ends. The cold air holes 2 are inclined, and their tops face the optical cable junction module 101. Cold air moving upwards in the cold air chamber 103 blows from the cold air holes 2 onto the optical cable junction module 101 to cool it. A guide plate 201 is fixedly connected to the upper part of the bottom of the cold air hole 2. The outwardly extending guide plate 201 guides the cold air moving upwards, thus guiding the cold air into the cold air hole 2 and the cold air chamber. The internal movable connection of 103 is a lifting bracket 202. Both ends of the lifting bracket 202 are fixedly connected with multiple parallel closed plates 203. The closed plates 203 are slidably connected to the bottom of the cold air hole 2, and the top of the closed plate 203 is in contact with the bottom of the guide eaves plate 201. When the optical cable junction box is not suitable for direct air cooling on rainy days, the lifting bracket 202 drives the closed plates 203 to seal the cold air hole 2. Through the close contact between the closed plates 203 and the guide eaves plate 201, the sealing effect of the cold air hole 2 is effectively improved. When the optical cable junction box uses air cooling, the lifting bracket 202 drives the sealing plate 203 to descend, opening the cold air vent 2. The cold air moving from bottom to top in the cold air chamber 103 blows from the cold air vent 2 onto the optical cable junction module 101, providing air cooling for the optical cable junction module 101. When the optical cable junction box switches to water cooling, the lifting bracket 202 drives the sealing plate 203 to rise and close the cold air vent 2, effectively preventing high humidity cold air from contacting the optical cable junction module 101, thereby effectively preventing the optical cable junction module 101 from short-circuiting due to moisture.

[0019] Please see Figure 6 The fiber optic cable junction module 101 includes an environmental monitoring module. The input of the environmental monitoring module is connected to a temperature sensor and a humidity sensor. The temperature sensor monitors the temperature of the external environment of the fiber optic cable junction box to determine its heat dissipation requirements. The humidity sensor monitors the humidity of the external environment of the fiber optic cable junction box to determine which heat dissipation method is suitable. A lifting mechanism for driving the movement of the lifting bracket 202 is fixedly connected to the bottom of the cold air chamber 103. The output of the environmental monitoring module is connected to the opening and closing end of the lifting mechanism. The lifting mechanism is rotatably connected to the cold air chamber 103. The air chamber 103 consists of a threaded shaft 204 and a linkage bracket 205 externally threaded to the threaded shaft 204. The top end of the linkage bracket 205 is hinged to the lifting bracket 202, and the bottom end of the linkage bracket 205 is hinged to the top end of the herringbone plate 105. A drive motor 206 is fixedly connected to the bottom of the optical cable junction module 101. The output end of the drive motor 206 is fixedly connected to the threaded shaft 204. The drive motor 206 drives the threaded shaft 204, which in turn drives the linkage bracket 205 to retract and expand, thereby realizing the lifting mechanism's adjustment of the lifting bracket 202. The external environment of the optical cable junction box is monitored in real time by the environmental monitoring module to determine whether the environment is sunny or rainy. In order to better monitor the external environment of the optical cable junction box, optical sensors can also be used to detect the lighting conditions and particulate matter sensors to detect the air pollution conditions. Based on the environmental monitoring results, the heat dissipation method of the optical cable junction box can be switched and adjusted to effectively protect the optical cable junction module 101 inside the optical cable junction box.

[0020] Second implementation method: Compared to the first embodiment, the main additions are a rainwater funnel 3 and a water collection trough 302. The specific additions are as follows, while the remaining structures are the same as in the first embodiment.

[0021] Please see Figures 7 to 11A rainwater funnel 3 is fixedly connected to the top of the housing 1. The bottom of the rainwater funnel 3 is fixedly connected to the top of the cold air chamber 103. A top cover 301 is fixedly connected to the top of the lifting bracket 202. The top cover 301 is engaged with the top of the rainwater funnel 3. When the optical cable junction box is in a rainy environment, the top cover 301 is opened by raising the lifting bracket 202. The rainwater falling on the top cover 301 enters the rainwater funnel 3 from the edge and is then concentrated and sent into the cold air chamber 103 by the rainwater funnel 3. This allows the rainwater to soak the inner wall of the cold air chamber 103. Combined with the rising cold air in the cold air chamber 103, the rainwater evaporates faster, thereby achieving the desired effect. For water cooling of the optical cable junction module 101 inside the housing 1, the top of the eaves 201 is curved to form a water collection trough 302. The water collection trough 302 effectively improves the retention capacity of rainwater, making it easier to maintain a suitable water volume on the inner wall of the cold air chamber 103. Both ends of the water collection trough 302 are fixedly connected to end diaphragms 303. The end of the end diaphragm 303 away from the water collection trough 302 is fixedly connected to the lifting bracket 202. The end diaphragm 303 rises and bends with the lifting bracket 202, thereby raising both ends of the water collection trough 302 and preventing rainwater from leaking from both ends. After the lifting bracket 202 is lowered and restored, the end diaphragm... 303 descends and returns to its original position following the lifting bracket 202, allowing rainwater in the water collection trough 302 to drain from both ends. An overflow hole 304 is provided at the end of the water collection trough 302 closest to the cold air chamber 103. The bottom height of the overflow hole 304 is less than the height of the end of the water collection trough 302 furthest from the cold air chamber 103. After rainwater enters the cold air chamber 103, the uppermost water collection trough 302 in the cold air chamber 103 is filled first. Once full, water is then pumped down to the next lower water collection trough 302 through the overflow hole 304, thus filling the water collection trough 302 from top to bottom. A seepage plug 30 is fixedly inserted into the bottom of the overflow hole 304. 5. The seepage plug 305 is T-shaped, and the bottom of the seepage plug 305 is in close contact with the surface of the cold air chamber 103. The seepage plug 305 is made of sponge material. The seepage plug 305 effectively reduces the water discharge efficiency of the overflow hole 304. The T-shaped design of the seepage plug 305 makes the overflowing rainwater evenly distributed on the inner wall of the cold air chamber 103, thereby effectively improving the rainwater wetting effect on the inner wall of the cold air chamber 103. The end of the sealing plate 203 near the cold air chamber 103 is provided with a sliding groove 306 that is slidably connected to the seepage plug 305. The sliding groove 306 effectively prevents the sealing plate 203 from affecting the seepage plug 305 during the lifting and lowering process. When the optical cable junction box relies on rainwater to dissipate heat from the optical cable junction module 101, the lifting bracket 202 rises to open the top cover 301. The rainwater falling on the top cover 301 enters the rainwater funnel 3 along the edge and is concentrated and sent into the cold air chamber 103 by the rainwater funnel 3, so that the rainwater wets the inner wall of the cold air chamber 103. Combined with the rising cold air in the cold air chamber 103, the evaporation of the rainwater is accelerated, thereby realizing the water cooling of the optical cable junction module 101 inside the box 1 by the cold air chamber 103. When rainwater enters the cold air chamber 103, the water collection trough 302 at the top of the cold air chamber 103 is the first to be filled with rainwater. After being filled, the water collection trough 302 transfers water to the water collection trough 302 at the next lower level through the overflow hole 304, thereby filling the water collection trough 302 from top to bottom. The seepage plug 305 effectively reduces the water discharge efficiency of the overflow hole 304, and the T-shaped setting of the seepage plug 305 makes the overflowing rainwater evenly distributed to the inner wall of the cold air chamber 103, thereby effectively improving the rainwater wetting effect on the inner wall of the cold air chamber 103.
