Description

Technical Field

[0001] The present invention relates to the field of electrical machinery and equipment manufacturing, and particularly to a gas-guiding and rain-proof cover plate and an intelligent temperature-controlled cable distribution box. Background Art

[0002] A cable distribution box is a key device for distributing electric energy in a power distribution system. Its main function is to safely and efficiently tap the electric energy of the main cable to multiple branch lines, reduce the risk of faults by reducing the number of direct joints of the main cable, and can integrate protection devices such as fuses to achieve short-circuit or overload protection. Its application scenarios are extensive, covering the main roads of urban distribution networks and the power distribution of residential communities, the multi-way power supply requirements of industrial and commercial areas, the independent power supply of public facilities (such as street lights and monitoring), and temporary power usage scenarios such as construction sites. As an outdoor device, it ensures the stability and reliability of power distribution.

[0003] However, the current outdoor cable distribution boxes still have certain deficiencies: First, the heat dissipation performance of the equipment is insufficient, and the heat generated during continuous operation is difficult to effectively discharge through the existing structure, resulting in a relatively high internal temperature. Moreover, the box is in a closed state, making it extremely easy for the temperature inside the box to be too high and cause a fire, posing a great safety hazard; Second, there is a risk of multi-path penetration. In a heavy rainfall environment, rainwater may directly invade the box body through the side heat dissipation holes due to strong winds, or a large amount of water may accumulate on the surface of the box body and penetrate into the internal space through structural gaps, easily causing damage to the inside of the cable distribution box; In addition, if professional maintenance is not carried out in a timely manner after the rain, the residual moisture on the surface of the box body will cause oxidation and rust of metal components. This corrosion phenomenon not only destroys the integrity of the equipment appearance but also significantly reduces the structural strength and service durability of the box body, significantly shortening the normal working time of the equipment. These problems will directly affect the reliability and safety of the power distribution system.

[0004] Therefore, those skilled in the art are committed to developing a gas-guiding and rain-proof cover plate and an intelligent temperature-controlled cable distribution box. Summary of the Invention

[0015] The beneficial effects of the present invention are as follows: Through the collaborative design of a dynamic sealing structure and an adaptive heat dissipation system, the present invention automatically closes the heat dissipation port and switches to the air curtain diversion heat dissipation mode in strong rainfall weather, and at the same time uses hot air flow to dry the surface of the box body, significantly improving the waterproof and moisture-proof performance (the humidity is reduced by more than 65%), avoiding the problems of excessive temperature rise (temperature rise ≤ 15K) caused by insufficient heat dissipation of traditional equipment and rust caused by rainwater penetration, taking into account all-weather efficient heat dissipation and sealing protection, reducing the fire risk and extending the service life of the equipment, and reducing the need for manual maintenance through intelligent control by sensors.

[0030] The present invention will be further described below with reference to the drawings and embodiments. It should be noted that in the description of the present invention, the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific manner, and therefore should not be construed as a limitation of the present invention. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0031] As Figures 1-6 shown, a kind of air guide and rainproof cover plate includes a cover plate body 1, and a communication groove 11 is provided on the cover plate body 1 as an installation basis. In this embodiment, the communication groove 11 is circular. In other embodiments, the communication groove 11 can also be set to other shapes according to actual needs, such as rectangular, square, oval or other special shapes. At least one air flow channel 12 is provided on the communication groove 11. In this embodiment, four air flow channels 12 are provided, and the four air flow channels 12 are circumferentially spaced along the communication groove 11. This setting can maximize the air flow efficiency. In other embodiments, the air flow channels 12 with other quantities or other distribution methods can also be set according to actual needs.

[0032] An air flow channel 12 is provided with an air guiding eaves 13 at one end far away from the communication groove 11. The air guiding eaves 13 is arranged along the circumferential direction of the cover plate body 1. One end of the air flow channel 12 is communicated with the air guiding eaves 13, and the relative other end is communicated with the communication groove 11. By arranging the air guiding eaves 13, the functions of exhausting air and blowing water are achieved. Specifically, at least one blowing groove 13a is formed on each inwardly inclined side wall of the air guiding eaves 13. In this embodiment, two blowing grooves 13a are arranged on each inwardly inclined side wall of the air guiding eaves 13, and the two blowing grooves 13a are arranged at intervals. By arranging the blowing grooves 13a, rainwater is blown and a wind curtain is formed to prevent rainwater from accumulating on the air guiding eaves 13. Further, a plurality of drying holes 13b are arranged at intervals on each outwardly inclined side wall of the air guiding eaves 13. By arranging the drying holes 13b, the surface of the box body 2 mentioned later in the present invention is dried, so as to further improve the moisture-proof performance of the equipment and ensure that the equipment can operate normally in a humid environment.

[0033] A blowing platform 14 protrudes from the top of the cover plate body 1, and a plurality of water blowing holes 14a (not shown in the figure) are circumferentially distributed on the side wall of the blowing platform 14. In this embodiment, the water blowing holes 14a are arranged to be 12, and the 12 water blowing holes 14a are circumferentially arranged at intervals on the side wall of the blowing platform 14. The water blowing holes 14a are communicated with the communication groove 11, and air can escape after flowing through the blowing holes along the communication groove 11. This design can blow rainwater to form a wind curtain, reduce the scouring of rainwater on the cover plate body 1, avoid the accumulation of rainwater on the cover plate, and reduce the influence of rainwater on the equipment.

[0034] As Figures 7-13 As shown, the present invention also provides an intelligent temperature-controlled cable branch box, which includes the air guiding and rain-proof cover plate as described in any one of the above. It also includes a box body 2, and a driving frame 21 is slidably fitted in the box body 2. In this embodiment, the sliding fit is a threaded fit. Specifically, an outlet box 3 is arranged outside the box body 2, a driving motor 31 is arranged in the outlet box 3, a driving screw 32 is connected to the output shaft of the driving motor 31, and the driving screw 32 is threadedly connected to the driving frame 21. When in use, the driving motor 31 drives the driving screw 32 to rotate as a power source, and the driving screw 32 is threadedly engaged with the driving frame 21 to drive the driving frame 21 to move up and down along the driving screw 32. Further, to improve the flatness of the inner side wall of the box body 2, a driving groove 33 can be arranged on the box body 2, and the driving screw 32 is arranged in the driving groove 33 to improve the flatness of the inner side wall of the box body 2 and expand the available space inside the box body 2.

[0035] At least one sliding frame 22 is arranged on the driving frame 21. In this embodiment, the sliding frame 22 is arranged to be two, and the two sliding frames 22 are respectively arranged at both ends of the driving frame 21. In other embodiments, the number of sliding frames 22 can also be set according to the size of the box body 2. Further, a connecting frame 4 can be arranged to connect the driving frame 21 and the sliding frame 22.

[0036] The sliding frame 22 serves as an installation base, on which a heat dissipation frame 23 is rotatably fitted. A plurality of heat dissipation fans 23a are provided on the heat dissipation frame 23 at intervals. The rotation of the heat dissipation fans 23a promotes the air exchange between the box body 2 and the outside, so as to achieve the functions of cooling and ventilation. In this embodiment, the rotational fit is a hinged fit. An articulated shaft 5 is provided between the sliding frame 22 and the heat dissipation frame 23. A torsion spring 51 is sleeved on the articulated shaft 5. In the freely extended state of the torsion spring 51, the sliding frame 22 and the heat dissipation frame 23 are vertically distributed.

[0037] A heat dissipation port 6 corresponding to the heat dissipation frame 23 is provided on the side wall of the box body 2. The provision of the heat dissipation port 6 facilitates the discharge of the hot air in the box body 2. A dust-proof net (not shown in the figure) is fixedly connected to the inner wall of the heat dissipation port 6 to prevent dust in the air from entering the interior of the box body 2.

[0038] In the initial state, the heat dissipation frame 23 is in a vertical state and cooperates with the heat dissipation port 6 for exhaust. When a weather change is detected, the sliding frame 22 can push the heat dissipation frame 23 to be converted from a vertical state to a horizontal state. Specifically, a guide groove 24 corresponding to the heat dissipation frame 23 is provided on the inner wall of the box body 2. The guide groove 24 includes a first guide section 24a and a second guide section 24b. Among them, the first guide section 24a extends in the vertical direction, the second guide section 24b extends in the horizontal direction, and the first guide section 24a and the second guide section 24b are connected by an arc-shaped edge for transition. The guide groove 24 plays a guiding role. A guide rod 25 is slidably connected in the guide groove 24. One end of the guide rod 25 away from the guide groove 24 is fixedly connected to the heat dissipation frame 23. During use, the sliding frame 22 pushes the heat dissipation frame 23 to displace in the vertical direction. When the heat dissipation frame 23 displaces, it runs along the track of the guide groove 24 driven by the guide rod 25, so as to realize the conversion from a vertical state to a horizontal state. This design can complete the conversion of the heat dissipation direction of the heat dissipation frame 23 when the weather changes.

[0039] A sealing plate 26 is slidably connected to the bottom of the sliding frame 22. The sealing plate 26 is arranged in parallel with the heat dissipation frame 23. By arranging the sealing plate 26, the heat dissipation port 6 is closed after the displacement of the heat dissipation frame 23. Specifically, at least one sliding rod 22a is provided at the bottom of the sliding frame 22. In this embodiment, two sliding rods 22a are provided, and the two sliding rods 22a are spaced apart. A limiting ring 22b is sleeved outside the sliding rod 22a. The limiting ring 22b is fixedly connected to the sealing plate 26. The inner diameter of the limiting ring 22b is larger than the outer diameter of the sliding rod 22a. The sliding rod 22a and the sealing plate 26 are slidably connected within the limiting ring 22b. A limiting plate 22c is provided at one end of the sliding rod 22a away from the sliding frame 22. The diameter of the limiting plate 22c is larger than the inner diameter of the limiting ring 22b. By arranging the limiting plate 22c, the limiting rod is prevented from slipping out of the limiting ring 22b. An elastic member 22d is provided on the limiting plate 22c. In this embodiment, the elastic member 22d is a straight spring. In other embodiments, other similar products can also be used, such as leaf springs, helical springs or gas springs, etc. One end of the elastic member 22d is connected to the limiting plate 22c, and the opposite end is connected to the limiting ring 22b. In the free extension state of the elastic member 22d, the top of the limiting ring 22b abuts against the bottom of the sliding frame 22.

[0040] Guide rails 27 are provided on both opposite sides of the sealing plate 26. The guide rails 27 are slidably connected to the sealing plate 26. The sealing plate 26 can slide up and down along the guide rails 27. A limiting protrusion (not shown in the figure) is provided on one side of the guide rail 27 close to the sealing plate 26. The bottom of the limiting protrusion is flush with the bottom of the heat dissipation port 6. A limiting block 26a matching the limiting protrusion is provided on the sealing plate 26. When the sealing plate 26 moves upward, the bottom of the limiting protrusion abuts against the top of the limiting hole, thereby realizing the limitation of the vertical movement of the sealing plate 26.

[0041] In this embodiment, a flow guide cover 7 is further provided inside the box body 2. The flow guide groove has a "conical" structure with a smaller upper part and a larger lower part. By arranging the flow guide cover 7, it is convenient for the air flow inside the box body 2 to enter the communication groove 11.

[0042] In this embodiment, a rubber pad 8 is further provided on the side of the driving frame 21 away from the box body 2. By arranging the rubber pad 8 to block the driving frame 21, the internal components of the box body 2 are protected from being affected, and the flatness inside the box body 2 is improved.

[0043] In this embodiment, a sensor 9 is further provided on the top of the cover body 1. By arranging the sensor 9 to sense rainfall, the corresponding sealing and heat dissipation programs are automatically started, which improves the automation and intelligence level of the equipment, reduces manual intervention, and improves the operation efficiency and safety of the equipment.

[0044] When in use, on sunny days or under normal weather conditions, the heat dissipation frame 23 is in a vertical state and cooperates with the heat dissipation port 6 to dissipate heat; in heavy rainy weather, the sensor 9 arranged on the top of the cover body 1 starts the drive motor 31 when it senses rain, and the drive motor 31, as a power source, drives the drive screw 32 to rotate, thereby driving the drive frame 21 and the sliding frame 22 to slide up and down along the inner wall of the box body 2. When the sliding frame 22 moves, the heat dissipation frame 23 arranged on the sliding frame 22 also moves synchronously, and the heat dissipation frame 23 slides along the guide groove 24 under the action of the guide rod 25, thereby realizing the conversion of the heat dissipation direction.

[0045] When the sliding frame 22 moves, the sliding rod 22a arranged at the bottom of the sliding frame 22 drives the sealing plate 26 to move synchronously through the elastic member 22d and the limiting ring 22b. When the sealing plate 26 reaches the specified position, the limiting protrusion arranged on the guide rail 27

[0046] The sealing plate 26 is in contact with the stop block 26a provided on the sealing plate 26. At this time, the sealing plate 26 is limited and stops moving to complete the blocking of the heat dissipation port 6. After the sealing plate 26 is limited, the sliding frame 22 pushes the heat dissipation frame 23 to continue moving along the guide groove 24. At this time, the elastic member 22d will be compressed, and the sliding frame 22 is out of contact with the sealing plate 26. When the guide rod 25 moves along the guide groove 24 to the tail of the guide groove 24, the heat dissipation frame 23 has completed the switch from the vertical state to the horizontal state. At this time, the heat dissipation fan 23a on the heat dissipation frame 23 blows the hot air in the box body 2 to the air guide cover 7, and the air guide cover 7 collects the hot air into the connecting groove 11. The hot air in the connecting groove 11 enters the air guide eaves 13 and the air blowing platform 14 along the air flow channel 12 and the water blowing hole 14a respectively, and the air guide eaves 13 and the air blowing platform 14 are used to realize the water blowing and drying of the box body 2 and the cover body 1. When the sensor 9 senses that the rain has stopped, the driving motor 31 is turned off, and the elastic member 22d drives the heat dissipation frame 23 to move back to the position of the heat dissipation port 6 under the effect of elastic recovery.

[0047] The present invention automatically closes the heat dissipation port 6 and switches to the wind curtain diversion heat dissipation mode in heavy rain weather through the coordinated design of the dynamic sealing structure and the adaptive heat dissipation system. At the same time, the hot air flow in the box 2 is used to dry the surface of the box 2, which significantly improves the waterproof and moisture-proof performance of the equipment (humidity is reduced by more than 65%), and avoids the temperature rise exceeding the standard (temperature rise ≤ 15K) and the rust caused by rainwater penetration caused by insufficient heat dissipation in traditional equipment. At the same time, the present application takes into account all-weather efficient heat dissipation and sealing protection, reduces the risk of fire and prolongs the life of the equipment, and reduces the need for manual maintenance through intelligent control of sensors.

[0048] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
